    [0002] EXTERIOR REAR VIEW MIRROR ROTATION MECHANISM FOR VEHICLES
    [0004] The present invention refers to a mechanism for rotating a rear-view mirror of the lateral exterior type, wherein said rotation mechanism makes it possible for the rear-view mirror to pass, at least, between the positions usually referred to as parking and driving in a motorized manner and / or or manual.
    [0006] Background of the invention
    [0008] The exterior side mirrors of vehicles, as vehicle components, are immersed within the requirements of minimizing production costs and assembly times / costs.
    [0010] These needs that the automotive sector shows in all its products related to the parts that make up the vehicle, mean that in the state of the art many sets of mirrors have been developed with designs that try to simplify both the parts and the number of said parts used, as well as the reliability and efficiency in their operation, and the ease and speed of assembly, in order to reduce the final cost of the rear-view mirror.
    [0012] The known rotation mechanisms and which, therefore, are considered to be part of the known state of the art, are based on an actuator that, through the operation of an electric motor and a kinematic chain, transmits the movement to the parts. of the axis of rotation of the mirror, achieving said displacement of rotation between the predetermined positions.
    [0014] To achieve the location of the mirror in said angular positions, at least, for driving and parking, there are anchor points between fixed parts and parts that have rotational movement with respect to the previous ones. In the state of the art, complementary ramps and protrusions are used between said pieces, which allow the exit from the anchoring position by the rotary movement.
    [0016] This system of ramps and protrusions causes a longitudinal displacement parallel to the axis of rotation, with which, to avoid the easy overcoming of the said ramps, as well as to keep the set of parts used in the rotation movement in a compact manner, there is an elastic element, usually a spring, which compresses the set of all the parts of the rotation mechanism and presses so that the anchoring of both the crown or pinion that transmits the movement of the kinematic chain is not saved, and so that the anchoring of the position on the fixed base of the rearview.
    [0018] This configuration, as it requires considerable pressure from the spring that exerts force on the entire assembly and its different anchorages of different sets of pieces, requires considerable energy consumption to be able to make these turning movements that have to save the ramps to its unmoored and therefore overcome the spring pressure.
    [0020] It is also known in the State of the Art to use parts with ramps that can be saved in two directions of rotation, which can create, in the event of an excess in the turning radius, a disengagement from the predetermined position or not correctly reaching she.
    [0022] Finally, known mechanisms also use different steps in the transmission of the rotary movement between pieces that form anchoring assemblies, having to carry out the passage to a predetermined anchoring position, there are intermediate pieces. This requires carrying out a first positioning of the piece that transmits the movement in said intermediate piece so that, later, it is the set of the two previous ones that moves to anchor or exit the anchoring of the piece that marks the predetermined positions of the rear view mirror operation.
    [0024] This implies the realization of at least two relative movements between two assemblies, translating into a greater possibility of malfunctions, greater energy consumption and a greater number of pieces, with the consequent increase in the cost of the final product.
    [0026] Description of the invention
    [0028] The objective of the present invention is to provide an exterior rear-view mirror rotation mechanism for vehicles, as well as to provide a rear-view mirror that includes said rotation mechanism, which manages to solve the aforementioned drawbacks, presenting other advantages that will be described below. .
    [0029] In the present description, elevation movement is understood to be the one corresponding to the longitudinal movement in a direction parallel to the axis of rotation, usually vertical due to the usual positioning of the rear-view mirrors and the usual systems for folding the rear-view mirror towards the body, wherein said movement Longitudinal movement is done by moving in the opposite direction to that of fixing the mirror on its base attached to the vehicle.
    [0031] In the same way, the usual operating positions of the rear-view mirror are understood to be those taken by the mirror when driving and at rest in the parking lot. In driving mode, of course, the mirror is deployed, in a safe locked position that allows viewing through it from inside the vehicle. In parking mode, the mirror is folded towards the body, protecting the mirror and reducing the overall width of the vehicle in that static mode in which it is not driven. There is the possible counter-parking position, in which there is the possibility of turning out in the opposite way to the turning of driving to parking, where this position is used mainly as safety against blows that the mirror may receive, or specific manual actions.
    [0033] According to this objective, according to a first aspect, the present invention provides a rotation mechanism of an exterior rear-view mirror for vehicles, of those that perform the motorized and / or manual movement of the mirror, at least, between the established functional positions of parking and driving, pivoting on an axis jointly fixed to the base of the rear-view mirror which is in turn fixed to the body / door of the vehicle.
    [0035] The rotation mechanism has a motorized device for the transmission of the rotation movement by a kinematic chain to the traction parts installed on the fixed shaft that acts as a pivot. In this rotational movement, lifting movements of different parts of the mechanism are available to unlock the mirror from the functional positions in which it is fixed. There is also a spring or elastic element for compression of the assembly, which exerts longitudinal pressure on the locking position of the crown, integral with the axis of rotation.
    [0037] The rotation mechanism is characterized by comprising, at least:
    [0038] - an envelope, or box, that pivots with respect to the axis of rotation of the mirror and contains the rotation mechanism, or at least, the elements that move in solidarity with the rotation of the rotation mechanism, wherein said envelope has a surface that has of protrusions or ramp-shaped recesses, which come into contact with a pivoting base integral with a piece / area for support located at the base of the rear-view mirror;
    [0039] - a piece or area for support that is fixed and attached to the base of the mirror, which has the pivoting base with which the surface of the casing comes into contact during its rotation, wherein said pivoting base has protrusions or recesses in the form of a ramp, in a complementary way to those located on the surface of the envelope;
    [0040] - a crown or pinion, which is part of the kinematic chain for the transmission of movement, where said crown or pinion has a contact surface for anchoring it in a retaining element or piece. This element or retaining piece does not have radial or longitudinal movement with respect to the crown or pinion, the anchoring being made between the contact surface of the crown, with the element or retaining piece, by means of protrusions or recesses in the form of ramp, in a complementary way between one piece and another;
    [0041] - an element or part for retaining a crown or pinion that is fixed to the axis of rotation without radial or longitudinal movement with respect to it, which has a surface in contact with the crown with protuberances or recesses in the form of a ramp, in a complementary manner to those arranged on said contact surface with the crown or pinion.
    [0043] In the previous configuration, it is characteristic that, between the casing or box that pivots on the axis of rotation and the element or part for retaining the crown or pinion, there is a gap that allows longitudinal displacement of the casing or casing. along said axis of rotation for unlocking, overcoming the corresponding ramps between surfaces in contact, having independent elastic means installed between them that exert pressure to maintain the original separation, without the elastic element or compression spring of the set intervening in the realization of pressure for the union of said two elements, without direct or indirect pressure on the envelope or box.
    [0045] It is also characteristic of the configuration of the invention that the unlocking movement between the casing or box that pivots on the axis of rotation and the piece or zone for support that is fixed is carried out directly without intermediate pieces that may have relative radial movement with respect to the envelope or box.
    [0046] Finally, it is also characteristic of the configuration of the invention that the ramp-shaped recesses that can be located in the casing or box that pivots on the axis of the rotation or located in the piece or area for support that is fixed, have a travel stop in the direction and direction of rotation of the enclosure or box towards the driving position, not salvageable by ramp, by way of interlocking in said position of conduction.
    [0048] This configuration allows the lifting movement of the casing or box to be free from the action of the spring or compression element of the assembly, with which the motorized rotation movement between parking lot and conduction does not have to save the pressure of said spring or compression element of the assembly, with which the energy consumed in said movements is lower, since whoever carries out this pressure in the anchoring position of the envelope at the base of the mirror is a single elastic element for said envelope and located between said surround and crown retainer.
    [0050] The spring acts by pressing the anchoring position of the crown or pinion on the part or retention element thereof, it maintains the pressure on the rest of the pieces and especially on the positioning of the crown or pinion on the element or retention piece, so that in motorized movements, it is not possible to unlatch said joint, while at the time of manually bringing the rear-view mirror to any of the positions, with the motorized device locked, it is by manual effort that the pressure of the compression spring is overcome , the crown and retaining piece joint is unlocked and allows manual movement of the rear-view mirror to any of the previous positions, parking and driving, as well as to the counter-parking position that is not normally reached in a motorized manner.
    [0052] In this way, there are independent pressure means for locking the crown and for locking the shell.
    [0054] Advantageously, it is also necessary that the configuration of the invention indicated, by performing a direct actuation between the casing or box that pivots on the axis of rotation and the piece or zone for support that is fixed, avoiding intermediate extra pieces with relative movement with them, simplifying the rotational movements between parts and therefore increasing simplicity and consequently reducing costs with respect to some known solutions.
    [0056] According to a possible embodiment of the invention, the elastic means arranged between the casing or box that pivots on the axis of rotation and the element or part for retaining the the crown or pinion, are formed by a wavy washer. This allows us to have the pressure element between the casing and its immediately superior piece, the crown retention piece, a pressure that can only be calculated for this joint of this set and be less than that necessary to join the entire mechanism set. as in the state of the art.
    [0058] According to one embodiment of the invention, the casing or box has a surface having protrusions that come into contact with the ramp-shaped recesses of the pivot base. This preferred configuration makes it possible to interlock the operating positions of the rear-view mirror, and allows movement to the other position, overcoming the ramps that make the rear-view mirror lifting movement.
    [0060] According to another embodiment of the invention, which can be combined with the previous ones, the element or piece of retention of the crown or pinion has a surface that has protrusions that come into contact and interlock with the ramp-shaped recesses of said crown or pinion. In the same way, this also preferred configuration allows manual movement of the rear-view mirror operating positions, with the motorized device locked.
    [0062] Preferably, the support surface on which the surface of the casing or box rotates can be a part independent of the axis of rotation and of the fixed base of the rear-view mirror, integrally coupled to at least one of them.
    [0064] As an alternative to the foregoing, the support surface on which the surface of the housing or box rotates can be a surface integrated in the axis of rotation and / or in the fixed base of the rear-view mirror.
    [0066] According to a second aspect, the present invention proposes a rear view mirror, which is characterized by the fact that it includes a rotation mechanism such as that indicated in the present description. The resulting rear-view mirror manages to carry out the lifting movement with a lower energy consumption, with greater simplicity of the parts that make up the mechanism and with the performance of direct movements and, therefore, with the need to perform fewer such movements. for each shift between positions.

    [0097] Description of a preferred embodiment
    [0099] Next, various embodiments of the vehicle exterior rear view mirror rotation mechanism are described, as well as the rear view mirror that includes said rotation mechanism of the present invention, with reference to the figures indicated above.
    [0101] In the operation of the rear-view mirror (100) of the present embodiment, its positioning is carried out in two positions in a motorized and manual way, the driving position and the parking position, and in a position exclusively with manual operation such as the counter position. parking lot, but you can return it to the driving position motorized.
    [0103] The passage from one position to another of the rear-view mirror (100) is carried out thanks to the rotation mechanism (10) that is integrated inside said rear-view mirror (100), as can be seen in figures 1 to 3 . This rotation mechanism (10) is mounted around a mounting assembly that is fixed to the base (13) of the rear-view mirror (100) and which in this case is formed by a rotation axis as a pivot element (12 ), or nipple, together with the fixed piece (11) that is integrated in said pivot element (12), which in turn is fixed to the base (13) of the rear-view mirror (100).
    [0104] The rotation mechanism (10) has an envelope (16) that contains inside the different elements that perform the function of the rotation mechanism (10). At the base of said envelope (16), as can be seen in Figures 4 to 9, there is a surface with protrusions (18) that come into contact with the surface of the support piece (11), which is It is fixed to the base (13) of the rear view mirror (100). The support piece (11) acts as a pivoting base with which the protrusions (18) come into contact during their rotation, having ramp-shaped recesses (19) in said pivoting base, in a complementary manner to the protrusions (18 ) on the surface of the casing (10).
    [0106] Between the casing (16) and the next piece mounted on it, which is a fixed retaining piece (14) of the crown (6), there is a gap (d) comprised in the longitudinal mounting axis (M), where said separation (d) allows the longitudinal displacement of the envelope (16), and therefore, of the elements that are fixed to it (16).
    [0108] This longitudinal displacement occurs at the moment in which the protrusions (18) of the casing (16) move in their rotation along the ramps (19) of the support piece (11).
    [0110] Between the casing (16) and the retaining piece (14) there is an elastic element in the form of a wavy washer (9) which, when the casing (10) moves in the longitudinal axis of the mounting (M), approaching the retaining piece (14), said washer (9) exerts a separation force between said pieces (16-14) that favors the original, separated position.
    [0112] The retention piece (14) is fixed, being fixed longitudinally and radially to the pivot element (12) by anchoring said retention piece (14) in the fixed support piece (11) which is also integral with the pivot element (12) and to the base (13) of the rear view mirror. This solidity is achieved by the coupling of the piece (14) in the protrusions (22).
    [0114] As can be seen in Figures 10 to 13, the retaining piece (14) has protrusions (30) into which the crown (6) fits, which (6) is pressed to keep it in place. engaged position with the retaining piece (14) by the pressure action of a spring (4). In order to unlock this locking position of the crown (6) in the retaining piece (14), the spring pressure must be overcome and the ramps formed by the protrusions (30) must be overcome.
    [0115] This action is carried out by manual means, since the turning movement by means of the motorized device and its kinematic chain (8), is blocked in said direction of rotation towards the counter-parking position, by means of a stop element (21) of the turn. When performing the manual action of rotating the rear-view mirror (100) towards the counter-parking position, it is necessary to have the envelope (16) locked in that direction of rotation, by overcoming the resistance of the spring (4) and the protuberances (30) of the retaining piece (14), the crown is unlocked by carrying out a lifting action of the casing (16), saving the stops (21) and proceeding to rotate the rear-view mirror to the counter-parking position.
    [0117] The pressure action of the spring (4) ends in the retention piece (14) since it is fixed and without longitudinal displacement, which means that it does not transmit pressure to the elements that are on the other side, such as the envelope (16) which, as seen, has its own pressure element to fix the operating positions of the rear-view mirror (100) by means of the wavy washer (9).
    [0119] In the motorized movement of the rear-view mirror (100), starting from the original driving position, as can be seen in Figures 4 and 5, the protrusions (18) of the casing (16) are in the most Lowering of the ramps (19) in which they have a direction of rotation blocked by stops (21) that prevent said rotation towards the counter-parking position, as indicated above. At that point, where the separation distance (d) between the casing (16) and the retaining piece (14) is maximum, the wave washer (9) is relaxed. Said washer (9), as the casing (16) moves along the ramp (19) in the direction of rotation towards the parking position, it will be pushed towards the retaining piece (14) with which the washer ( 9) will exert a pressure against said advance of the protrusions (18) of the casing (16) along the ramp (19).
    [0121] In the reverse movement, in which the motorized device (2, 8) rotates from the parking position to the driving position, the protrusions (18) the envelope (16) moves in its rotation through the ramps (19), until reaching its stop position (21).
    [0123] As an alternative to the previous embodiment, the corrugated washer (9) could be replaced by a similar elastic system that allows it to be located between the casing (16) and the retaining piece (14) of the crown (6).
    [0125] Also alternatively, it may be necessary that the pieces that have protrusions to engage in complementary recesses to fix positions, can be interchanged their configuration on the reverse and instead of having a protrusion, have complementary recesses and the other piece of protuberances instead of recesses.
    [0127] The support piece (11), alternatively, can form part of the pivot element itself (12) or of the base itself (13) of the rear-view mirror (100)
    [0129] Although reference has been made to a specific embodiment of the invention, it is evident for a person skilled in the art that the rotation mechanism of the exterior rear view mirror for vehicles, as well as the rear view mirror that includes said rotation mechanism described is susceptible of numerous variations and modifications, and that all the aforementioned details may be substituted by other technically equivalent ones, without departing from the scope of protection defined by the appended claims.
