    Technical area
    The present invention relates to a watch module, including a watch module containing a watch movement for an electromechanical watch.
    State of the art
    There is generally for electromechanical watches a printed circuit board (or PCB for "Printed Circuit Board") carrying a part or all electronic and electrical components, such as motors, which can set in motion and adjust the clock movement and in particular the needles.
    Generally, this printed circuit board is attached to the watch plate and is specific to each model of the watch. In the case where the watch performs several functions, it is generally used several printed circuit boards, each circuit board can be dedicated to a particular function of the watch.
    Thus, the documents US 2004 240 323, US 2006 140 065, US 5 446 703 and US 2010 220 559 have a system for fixing the printed circuit board with screws on fixing studs.
    Still in EP 1 211 578 a system for fixing the printed circuit board by compression on the fixing lugs. Also, DE 20 2014 008 505 U1 discloses a system for fixing the printed circuit board by means of a latching system with hooks comprising an elastically deformable arm.
    In these systems, the withdrawal and the change of the printed circuit board is done by a manipulation requiring most of the time the use of a dedicated tool. In addition, in the case of use of screws, there is the risk of loss of these screws in particular in the housing, and in the case of elastic portions, there is a risk of breaking them, thus making their reuse impossible. It follows the loss of the part which carries these broken elastic portions, and in particular of the circuit board when it carries these elastic portions.
    Brief summary of the invention
    An object of the present invention is to provide a watch module with a printed circuit board free from the limitations of such known watch modules.
    Another object of the invention is to provide a watch module with a printed circuit board whose removal or change of printed circuit board is easy, and if possible without special tools.
    Another object of the invention is to provide a watch module with a single printed circuit board to carry the watch movement, making the watch module adaptable to a large number of configurations, including different configurations of the watch movement.
    Another object of the invention is to provide a watch module with a single circuit board for wearing the watch movement, making the watch module capable of performing several functions.
    According to the invention, these objects are achieved in particular by means of a watch module comprising a printed circuit board (PCB), a first platinum ring comprising a bottom wall and a cylindrical side wall delimiting a housing. said side wall extending orthogonal to the bottom wall and being provided with first locking elements, and a second ring equipped with second locking elements, wherein the printed circuit board is adapted to be retained in said housing when the first locking elements cooperate with the second locking elements in a locked position.
    It is understood that the first ring and the second ring form, when they cooperate in the locked position, a cage, in the sense of an enclosure with openings, enclosing and retaining the printed circuit board. Indeed, in this locked position, the printed circuit board is trapped in the housing formed between the first ring and the second ring: the printed circuit board is retained in this housing as long as the first locking elements are engaged with the second locking elements in the locked position. Then, to release the printed circuit board, simply disengage the first elements of the second locking elements, whereby the first ring and the second ring are separable and the circuit board is able to leave the housing, for be replaced, repaired or reconfigured (change of components carried by the printed circuit board).
    In the locked position, the first ring and the second ring leave free access to at least one of the two faces of the printed circuit board, and preferably to both sides of the printed circuit board. In addition, advantageously, the configuration is such that it is the greater part of the surface of one (or both) faces of the circuit board that is available to carry the required components, because not covered by the first ring and the second ring.
    This solution has the advantage over the prior art not to use a portion of the printed circuit board for attaching the printed circuit board to a support. In this way there is no risk of damaging the printed circuit board during its removal / change and moreover it frees the location or locations previously used for the fasteners, increasing the surface and the possibilities of arrangement of elements on the printed circuit board.
    Preferably, the watch module comprises a single printed circuit board (PCB). This single circuit board can advantageously carry all the elements of the watch movement. This single circuit board can advantageously fulfill all the functions of the electromechanical watch with the watch module according to the invention.
    The first locking elements and the second locking elements preferably form a reversible bayonet type locking system.
    In this way, the locking / unlocking operation between the first locking elements and the second locking elements, therefore between the first ring and the second ring, is effected by a relative movement between the first ring and the second ring. ring, which can be manual or automatic, without any particular tool. Indeed, this relative movement for locking / unlocking between the first ring and the second ring comprises a relative rotation between the first ring and the second ring about their radial axis of symmetry.
    Advantageously, said printed circuit board is reversible in that it can be mounted in said housing with one or the other of its faces directed towards the bottom wall of the first ring, in said locked position. . This provides a significant advantage since, thanks to this arrangement, the same printed circuit board can be used with the assembly formed by the first ring and the second ring, not only in the configuration where it is one of two faces. (use recto) which receives and carries the components, including electronic, including those of the watch movement, but also in the configuration where it is the other of its two faces (use back) which door receives and carries the components.
    According to a preferred arrangement, the bottom wall of the first ring comprises at least one first positioning element and the printed circuit board comprises at least one second positioning element capable of cooperating with said first positioning element in order to maintain the first ring and the printed circuit board in a predetermined relative angular position. In this way, it ensures the proper angular placement, and maintaining in this correct angular position of the printed circuit board in the housing, and therefore the circuit board printed with respect to the first ring.
    [0020] Preferably, the first positioning elements and the second positioning elements comprise either notches or tongues. In a first case, the first positioning elements are notches and the second positioning elements are tabs. In a second case, the first positioning elements are tabs and the second positioning elements are notches. In other cases, some of the first positioning elements are tabs and others are notches and some of the second locating elements are tabs and others are notches. Each time, the nature of each of the pair of elements comprising a first positioning element and a second positioning element is chosen so that the tabs cooperate with the notches by shape complementarity, that is to say a tongue housed in a notch. Thus, the radial position (polar coordinates) of the notch allows the reception of the corresponding tab. Preferably, the extent of the notch allows the reception of the corresponding tongue, with a possibility of relative movement between the tongue and the notch almost zero or very limited. In particular, the angular extent of the notch allows the reception of the corresponding tongue, with a possibility of relative angular movement between the tongue and the slot almost zero or very limited (less than 5 °).
    The second positioning elements may be located along the border of the printed circuit board. In this way, the entire surface of the printed circuit board available for other uses is retained.
    The present invention also relates to an electromechanical watch comprising a watch module as described in the present patent application.

    Example (s) of embodiment of the invention
    [0024] Referring to FIGS. 1 and 2, showing a watch module 10 according to the present invention, respectively assembled and disassembled. It comprises a printed circuit board 12 intended to carry the components of a watch and in particular all the electrical or electronic components, but also the elements of the watch movement if it is a watch module for an electromechanical watch. Elements of the watch movement include, inter alia, needles, calendar dials and / or other mechanisms capable of being included in a watch movement.
    A first ring 14 forming a plate is disposed below and around the periphery of the printed circuit board 12. In other words, the printed circuit board 12 is received in a housing 141 defined by the first ring. 14. More specifically, the first ring 14 comprises an annular bottom wall 142 and a side wall 143 of cylindrical shape and circular section. Thus, the printed circuit board 12 is able to be placed on the bottom wall 142, being surrounded by the side wall 143 (see Figure 2).
    The watchmaker module 10 further comprises a second ring 16, intended to cap the printed circuit board 12, while being partially disposed in the housing 141, namely with the side wall 143 of the first ring 14 which encircles the second ring (see Fig. 1). This second ring 16 is annular and comprises a side wall 163 of generally cylindrical shape of circular section, extended at one of its ends in a radially internal direction by a terminal wall 162 in the form of a flange.
    Thus, in the mounted position, the side wall 163 of the second ring 16 is located inside the side wall 143 of the first ring 14, forming a ring whose lower face corresponds to the bottom wall 142 of the first ring 14 and whose upper face corresponds to the end wall 162 of the second ring 16.
    To allow the locking, reversible, between the first ring 14 and the second ring 16, and thus make the printed circuit board 12 prisoner of the housing 141, is used a locking system. More specifically, the side wall 143 of the first ring 14 comprises first locking elements 1431 turned in radially internal direction. In the illustrated embodiment, as can be seen in FIG. 2, these first locking elements 1431 comprise tabs extending over an angular sector of a few degrees. In addition, the side wall 163 of the second ring 16 comprises second locking elements 1631 rotated radially externally. In the illustrated embodiment, as can be seen in FIG. 2, these second locking elements 1631 comprise grooves extending over an angular sector of a few degrees.
    A preferred locking system is bayonet, namely that the first locking elements 1431 cooperate with the second locking members 1631 to achieve reversible locking, in a relative rotational movement between the first ring 14 and the second ring 16, once the first ring 14 is mounted in the second ring 16. This is the case on the locking system shown in FIG. 2 in which the tabs cooperate in complementary form with the grooves, or more generally the first locking elements 1431 cooperate in complementary form with the second locking elements 1631. In an alternative embodiment, the first locking elements 1431 comprise grooves and the second locking members 1631 have tabs.
    As can be seen from the figures, and in particular from FIG. 2, the first ring 14 and the second ring 16 have a radial symmetry, their central axis, respectively A1 and A.2, forming the radial axis of symmetry, being coaxial with each other in the locked position. In addition, in the locked position, the bottom wall 142 of the first ring 14 and the end wall 163 of the second ring 16 are spaced from each other, on either side of the housing 141.
    According to one embodiment, and as seen in FIG. 2, the bottom wall 142 of the first ring 14 comprises a compression element 1421 against which the printed circuit board 12 (PCB) bears in said locked position. One can provide a single compression element 1421 as in the case shown, or at least one compression element 1421 or several compression elements 1421. With this compression element 1421 which bears on the underside of the circuit board printed 12 (PCB), the latter is locked in the axial direction (direction parallel to the axes A1 and A2) in the housing 141. This compression element 1421 is for example a compression pin, and is therefore used to ensure the locking force and limit the games of the assembly.
    The angular position of the printed circuit board 12 in the housing 141 is kept fixed. For this purpose, the transition zone between the bottom wall 142 and the side wall 143 of the first ring carries a plurality of first positioning elements 1422 each able to cooperate with one of several second positioning elements 121 of the border of the card. printed circuit 12 (PCB), in particular by complementarity of form. In the illustrated embodiment, as it appears in FIGS. 2 and 3, the first positioning elements 1422 are projections and the second positioning elements 121 are notches adapted to receive one of said projections.
    The printed circuit board 12 is thus locked in the housing 141 in the locked position of the rings 14 and 16 (see Figures 1, 7 and 8). For this purpose, as indicated above, the printed circuit board 12 is also locked vertically (in the axial direction by considering the direction of the axis of the needles) between the bottom wall 142 (and in particular on the support element). compression 1421) of the first ring 14 and the second ring 16.
    Also, the side wall 143 of the first ring 14 is provided with at least one opening 1432 for the passage of a rod of a maneuvering member, such as a push button or a winding. Depending on the height of the side wall 163, the second ring 16, the latter may also be provided with a lateral opening 1632 for the passage of a rod of a maneuvering member, in correspondence with the lateral opening 1432 of the first ring 14.
    Advantageously, the bottom wall 142 of the first ring 14 is annular and defines an opening 1423 adapted to receive a battery 18. In this way, said battery 18 is in physical and electrical contact with the underside of the card. printed circuit 12, when the latter is disposed in the housing 141 in the locked position between the first ring 14 and the second ring 16.
    [0036] Advantageously, as it appears partially in FIGS. 1 to 3, 7 and 8, the printed circuit board (PCB) 12 carries the elements of a watch movement. Preferably, the printed circuit board (PCB) 12 carries all the elements of a watch movement.
    For this purpose, at least one bidirectional motor 20a is mounted on the printed circuit board (PCB) 12. Such a motor 20a makes it possible to set in motion a mobile element of the watch movement, in particular according to a rotational movement around the a vertical axis. Preferably, at least two bidirectional motors 20a, 20b are mounted on the printed circuit board (PCB) 12.
    In the embodiments illustrated in FIGS. 1 to 3, 7 and 8, three bidirectional motors 20a, 20b and 20c make it possible to move each of one of three needles (not shown) (hour hand, minute hand and second hand). In these embodiments, two other bidirectional motors 20d and 20e make it possible to set in motion two other needles not represented and constituting calendar hands (respectively day and month).
    To facilitate the assembly of bidirectional motors 20a to 20e, the watchmaker module 10 further comprises at least one support 21, 22 or 23 receiving said one or one bidirectional motor (or several bidirectional motors), this support 21, 22 or 23 being mounted on said printed circuit board 12. According to a first variant shown in FIGS. 1 to 4, said support 21 has a star shape with three branches, forming between them preferably 120 °. According to a second variant visible in FIG. 5, said support 22 has a shape with two branches which form a V (the two branches forming between them preferably 120 °). According to a third variant visible in FIGS. 1 to 3 and 6, said support 23 has a tongue shape (single branch shape).
    These different forms possible for the support, can support as much bi-directional motor as branches, and thus allow to achieve multiple arrangement between these supports 21 and / or 22 and / or 23, distributed on the surface of the card printed circuit board 12, with one or more supports. For example, one can mount together a support 21 with three branches with one, two or three supports 23 to a branch. According to another possibility, two supports 22 with two branches can be mounted together. According to yet another possibility of arrangement, it is possible to mount together a support 22 with two branches with one, two, three or four supports 23 to a branch. According to yet another possibility of arrangement, it is possible to mount together from one to six supports 23 to a branch.
    Preferably, at least one first support is disposed on the printed circuit board and carries at least one bidirectional motor for controlling a first function and at least one second support is disposed on the printed circuit board and door at least one bidirectional motor for controlling a second function. According to another preferred embodiment, a first support is disposed on the printed circuit board and carries at least one bidirectional motor for controlling a first function and a second support is disposed on the printed circuit board and carries at least one motor. bidirectional for controlling a second function. Thus, in this case the watch module 10 according to the invention allows the implementation of a multifunction watch.
    Thus, for example, the first function is the indication of the time and the second function is a calendar.
    If one refers to the embodiments illustrated in FIGS. 1 to 3, 7 and 8, it is a watch module 10 or 10 having a single support 21 with three branches with two supports 23 to a branch. The support 21 with three branches forms a star centered in the middle of the printed circuit board 12 and which is dedicated to the control of three needles rotating around the central axis of the watch module (controlled by bidirectional motors 20a, 20b and 20c ). This three-star star shape delimits three free zones on the surface of the printed circuit board 12, one between each pair of branches of the support 21. In FIGS. 10 and 10, two of these three zones are occupied by a support 23 single-handed, each for a bidirectional motor 20d and 20th ordering a calendar needle.
    In the arrangement of the watch module 10 of FIG. 7, the support 21 with three branches is arranged with two branches in the upper part of the dial delimited by the watch module 10 and the two supports 23 with one branch are arranged in the lower part of the dial delimited by the watch module 10: this way, the calendar function is housed in the lower part of the dial delimited by the watchmaker module 10.
    In the arrangement of the watch module 10 of FIG. 8, the support 21 with three branches is arranged with two branches in the lower part of the dial delimited by the watch module 10 and the two supports 23 with one branch are arranged in the upper part of the dial delimited by the watch module 10: this way, the calendar function is housed in the upper part of the dial delimited by the watchmaker module 10.
    To allow such versatility of mounting of the supports 21 and / or 22 and / or 23 on the printed circuit board 12, the latter is equipped with a multiplicity of fixing holes 12 (see FIG. the fastening of these supports 21 and / or 22 and / or 23, themselves drilled, for example by means of fixing screws 123.
