    The car door latch has a base plate on which a rotor is mounted. The rotor is fork shaped and engages with a stud on the door post. A spring loaded arm acts with a ratchet to prevent rotation of the rotor. The latch actuating arm (8) is pivoted on a hollow, internally threaded bush (16) secured to the base-plate (2). A screw (14) passes through the door panel (3), the rotor cover flange (17) and engages with the internally threaded bush. The strong mounting of the lever pivot eliminates distortion of the base plate for attempted forced opening.

    (54) SPLITTER MECHANISM FOR CAR DOOR
    one
    FIELD OF THE INVENTION The invention relates to a transport engineering, in particular to a locking mechanism for a car door.
    The closest technical solution to the invention is a locking mechanism for a car door, comprising a mounting element, a pivoting element mounted thereon associated with a latch, a ratchet rotatably attached to the pivoting element, and a pawl lever pivotally connected with the mounting element for locking the ratchet when releasing the latch when the door is closed, and the locking mechanism is attached to the door by means of mounting bolts, and the latch is attached to the door frame to interact with the door pivoted element.
    However, upon application of trial loads to the locking mechanism, the mounting member may be slightly bent, as a result of which the lever with the pawl disengages from the ratchet and the door opens. Theoretically, this bend can be prevented by positioning the fastening bolts around the axis of rotation of the lever with the pawl or by positioning the axis of the lever with the paw so that the force exerted by the ratchet on the lever is maintained with at least one bolt. However, in practice, the installation element should have minimal The dimensions for placing it inside the door, and the location of the locking mechanism, are dictated by 10 customer requirements, in which the axis of the lever with the dog cannot be positioned comfortably. Thus, in particular, for the locking mechanism of the rear door, the axis of the lever with the pawl should be very
    15 is close to the edge of the installation element and the forces generated apply the maximum bending stress to the latter. Bending can also be prevented by increasing the thickness of the installation element and making it with ribs, but this is relatively expensive.
    The purpose of the invention is. increase of service life of the locking mechanism.
    25
    The goal is achieved by the fact that the installation element is made in the form of a flat plate fixed to the door by means of bolts, an axis is set coaxially with one of the fixing bolts.
    30 on which the dog lever is mounted and connected to the ratchet, and the turnable element is connected to a tensioning handgun connected to the hook lever, the rotatable element is equipped with a lid, having a flat ixing part fixed on the outer surface of the plushina, and protruding the part, which is parallel to the locking part and is connected to the latter by its sides, except for the side that opposes said latch, and the rotatable element is mounted for rotation relative to the projecting part of the cover.
    In addition, the axis can be formed with a hole through which the said mounting bolt is passed,
    The axis can also be made hollow with internal thread, one end of the axis is attached to the mounting element, and the other end is provided with a head for mating with the inside of the lever of the pawl.
    The said flat plate and the fixing part of the cover are provided with holes for mounting said fixing bolts.
    The mechanism is provided with a pin, at one end of which a rotating element is fixed, and at the opposite end a plate is rigidly mounted, with which said tension is connected ;; on the spring.
    In addition, the mechanism is equipped with a locking device for fixing the rotary element and the drive T GO11, located; Enop is parallel to said plate for limited rotation around the axis, the latter, wherein said plate is made with a groove in which said traction bar is located, fixed in the groove by means of a leaf spring.
    The groove has an extended central part, and the ends of this groove are coupled with a thrust.
    The plate spring can be made of plastic and has a flat support part with two spaced ends, between which the plate part of the spring is located, with the said parts of the spring being made in one piece.
    The plate is fixed by a lid of the pivoting element fixed on the outer surface of the said flat plate and carrying a stop for a latch or a pivoting element to prevent the door from moving relative to the latch, while the stop is made of plastic and in one piece with the leaf spring.
    The groove for the lowering glass of the door is located in the area of the protrusion formed by the groove on the said flat plate.
    FIG. 1 shows an axonometric projection on one side of the locking mechanism of the rear door / FIG. 2 - then heh, on the other hand / in FIG. 3 - locking mechanism, side view; in fig. 4 is a section-dl in FIG. H; in fig. 5 is a section BB in FIG. 3; in fig. 6 - emphasis zshtselki, view in axonometry; Fig 7 - latch locking mechanism, view in axonometry; in fig. 8 - locking mechanism of the front door, a perspective view; in fig. 9 is a horizontal section BB in FIG. eight; in fig. 10 stop latch locking mechanism of the front door, a perspective view.
    The locking mechanism (Figs. 1-6) has an installation element 1 of an L-shaped cross section and includes a flat plate 2, which is screwed to the inner side of the side surface 3 (see Fig. 4) of the car door. A swivel element 4 in the form of a fork, made of plastic (polyamide) or made of metal with a rubber coating, is fixedly rotatable by means of a flat plate 2 and a cover 5, which is attached to the outside of said plate. The ratchet 7 is also secured to the pin 6, to which the pivot element 4 ,, j is attached. The flat plate 2 pivotally holds the lever 8 with the pawl engaging with the ratchet 7 to prevent it from turning and releasing the latch 9 i (see Fig. 7) from the rotary element 4 and the locking mechanism.
    The lever B with the pawl is acted upon by a conventional connecting mechanism (not shown) for unlocking the locking mechanism by means of an external button or other element, and for actuating the lever 8 with the pawl by means of the usual internal working member, a spring-loaded arm rotates on the supporting element 1. Step 10. Locking lever 11 is provided to prevent lever 10 from being misused or careless. To prevent lever 8 from moving with the pawl and to connect with a conventional internal locking element, such as a push button, instant locking lever 12 can be seen.
    The locking mechanism is attached to the inner side of the side surface 3 of the door with three fastening bolts 14 (Fig. 4) installed in the threaded holes 15 (see Fig. 3) in the locking mechanism. The bolts 14 are not concealed, as it has been found that this design avoids the formation of microcracks in the paint around the holes 15 and thereby increases the rust resistance. The cover 5 and the pivoting element 4 are passed through the hole in the side door 3, and this hole does not reach to the edge of the side surface, which prevents excessive exfoliation of the side surface of the door.
    The lever 8 with the pawl is mounted on the axis 16, the position of which allows the locking mechanism to be attached to the car door with fastening means in the form of a bolt 14 coaxially with the axis of rotation of the lever 8, thus securing the latter directly to the door (Fig. 5).
    The axis 16 is made in the form of a sleeve having a threaded hole through which the fastening bolt 14 can pass. One end of the sleeve is attached to the flat plate 2 by riveting its edge, and the other end is provided with a head that comes in contact with the inside of the lever 8 with the canine and keeps it in the absence of a locking mechanism and installed inside the door as a whole. After installing the locking mechanism inside the door, the fixing bolt 14 is screwed into the axial element 16. With this design of the locking mechanism, it is impossible to install the fixing bolts into the flat plate 2 to the right of the axis 16 and, thus, in the absence of the fixing bolt 14 entering the axle, large the force exerted on the pivoting element for opening leads the lever B with the pawl to the left (Fig. 3) and causes the flat plate 2 to bend beyond the plane of the drawing. This is avoided by inserting the fastening bolt 14 into the axis 16. The shape and location of the latter ensure that the lever 8 is not pressed while tightening the fastening bolt 14
    The pivot cap 5 contains a flat fastening part 17 and a pressed-out part 18, which runs parallel to the fastening part 17 at a certain distance from it and is connected to this fastening part by a cup 19 on all sides except for one, which includes a latch 9. Fastening part 17 is temporarily fastened to the flat plate 2 by rivets through the holes 20 (see FIGS. 3 and 4), and when installing the locking mechanism inside the door, the fasteners on the part 17 are permanently attached to the outside of the flat plate 2 by all three fastening bolts 14 The fastening part 17 has an opening in the axis 16 of the rotation of the lever with the pawl, which ensures the attachment of the lever 8 to the cover 5 of the rotating element. All three fastening bolts 14 attach the fastening part 17 and, thus, the pivot ring cap 5 directly to the door.
    With this design, the cover 5 of the rotary element fastener
    17 of the lid 5 strengthens the flat plate 2 .. It has been established that with such a design and special fastening of the axis 16 of the lever 8, the characteristic of the proposed locking mechanism can be improved by 40-50% compared to the known one, which established 1O tests under static load in accordance with with the standards a. UL (recommended practice of the Society of automotive and tractor engineers). In addition to
    0 of its high strength, the described locking mechanism is relatively compact and easily mounted in the door.
    The lever 8 with the pawl is brought into engagement with the temple 5 by the spring 7, and the rotatable element is in the position of release: it is fixed by means of one tension spring 21, which is connected to the protrusion 22, bent on the lever 8, and with the speaker 23, it is bent on the plate 24, riveted to the end of the trunnion 6, and thus connected to the rotation element 4 (see Fig. 1). Thus, the spiral spring 21 of linear action replaces the spiral
    5 is a compression spring of a possible action in a known device. It has been established that the spring 21 and the additional part (plate 24) can be made of approximately the same value. However, the spring / chin 21 takes up much less space in the direction of the axis 6. The fatigue strength of the spring 21 is relatively high and lasting, and it is better to use a spring that can withstand a large number of cycles with a less pronounced tendency to fatigue.
    An abutment is provided inside the cover 5 of the swivel member. In the specific case, the stop comes into contact with the head 25 of the latch 9 (see Fig. 7), however, it is possible to make this stop contact with the pivot member 4. In this case, the stop is intended to prevent the door from moving vertically relative to the latch 9. The stop is made of two parts - the outer ring 26 of plastic, which serves as a stop, and the inner rubber liner

    27. Oboyma 26 has a small protrusion
    28, which is clamped between the fastening part 17 of the cover 5 of the pivoting member and the flat plate 2, which ensures that the stop is held on
    5 place, and a small installation pin 29 (Fig. 5). The stop is part of the locking mechanism, not the latch assembly.
    In the locking mechanism for the front of the car door, the position of the axis 16 relative to the axis of the trunnion 6 is several. ko is different (Fig. 8-10). The second version of the locking mechanism does not have a locking lever that prevents actuation when careless
    five
    or inept handling, however, it has a pull 30 that runs parallel to the plane of the first plate 2 for limited rotation about its axis and actuating the locking element made in the form of locking lever 1 12. The other end of pulling 30 is connected in the usual way with outer car lock. The ha 30 is located in the channel 31, extruded in the flat plate 2, and is held in the position of the leaf spring 32. The channel 31 has a recessed central part 33 and therefore only the end portions of the channel 31 are in contact with the tension 30, which prevents the swings from swinging ti gi 30 with a large gap between the latter and channel 31 and pinching with a small gap or with insufficient straightness of the ty gi 30.
    Sheet Prune 32 is bent in its natural position and made of plastic, such as nylon, along with the sleeve 26, the stop (Fig. 10). The spring 32 is thus held in position by the lid 5 of the pivoting member. Sheet cover 32 has a flat rear part 34 and two protruding sections 35, at the intersection of which prrulsina 32 is located, departing from part 34 with the entire assembly as one unit. Leaf spring 32 firmly holds mr 30 in channel 31 and E,) () octkly prevents rattling. Listovna Prou :: {it has however (And not flat along bar 30, but snugly tightly to this bar at least r / iepe , its central part (Fig. 9).
    FIG. 8 and 9, the second function of the channel 31 is illustrated. The bulge 36 formed in the plate 2 by the channel 31 serves as a spacer element to prevent the closure mechanism from becoming contaminated through the guide channel 37 of the lowered side glass 38. The door structure may be such that the guide channel 37 is located at a distance of 2 to 3 mm from the bulge 36, however, the limits of the possible deflection or movement when used do not exclude the possibility of the contact of the guide channel 37 with the bulge 36.
    The options described can be widely modified. For example, axis 16 may have an enhanced head by extending this element (Fig. 5, dashed lines). In another case, due to the fact that the central part 33 of the channel 31 does not touch the grip 30, this section can be stamped to provide a gap.
    This design of the locking mechanism provides an increase in its service life.
