[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] like Figures 1 to 5 As shown, the utility model is a self-priming actuator for automobile door locks, characterized in that it includes: a housing 1; a transmission mechanism 2, which is arranged in the housing 1, and the transmission mechanism 2 includes a self-priming wire assembly 20 and at least two groups of transmission members 21 that are movably engaged with each other, wherein one group of transmission members 21 is movably engaged with the output end of the transmission mechanism 2, and the self-priming wire assembly 20 is movably engaged with the other group of transmission members 21, and when the transmission mechanism 2 is started, it can drive the self-priming wire assembly 20 to move relative to the housing 1; a mounting plate detachably connected to the sheet metal The mounting plate 3 is provided with a plurality of buffer members 30 at the periphery thereof, and a buckle portion 300 is formed at the end of each buffer member 30. The two side walls of the shell 1 are respectively formed with a left door lock buckle groove 10 and a right door lock buckle groove 11, and the buckle portion 300 is movably buckled in the left door lock buckle groove 10 or the right door lock buckle groove 11; the buckle portion 300 can be detached from the shell 1 when sliding along the open end of the left door lock buckle groove 10, and when the buckle portion 300 slides into the right door lock buckle groove 11, the mounting plate 3 is connected to the sheet metal of the right door.

[0034] In this embodiment, when the transmission mechanism 2 is started, the self-priming wire assembly 20 can be driven to move through the transmission of multiple sets of transmission parts 21, and finally the rotation of the external self-priming pull rod (not shown in the figure) is realized. The self-priming actuator has a simple structure and uses multiple sets of transmission parts 21 to effectively increase the torque when driving the self-priming wire assembly 20 to move, thereby improving the stability during operation. Moreover, the present solution also forms a buffer member 30 on the mounting plate 3 outside the shell 1, and the buffer member 30 can be used to buffer the vibration generated during the operation of the self-priming actuator. At the same time, the formed snap-on portion 300 can be flexibly snap-fitted with the left door lock snap-on groove 10 or the right door lock snap-on groove 11 on the two side walls of the shell 1. That is to say, when the self-priming actuator is installed on the right door lock, the snap-on portion 300 can be detached from the left door lock snap-on groove 10, and then the snap-on portion 300 can be used again to cooperate with the right door lock snap-on groove 11, and vice versa, thereby realizing the free switching of the installation position of the self-priming actuator. Therefore, the structure can quickly realize the free switching of the left door lock and the right door lock during installation under the same self-priming actuator structure, which is convenient to operate and reduces the manufacturing cost of the self-priming actuator.

[0035] like Figure 2As shown, preferably, the buffer 30 is made of rubber material, which provides convenience for installation and disassembly, and can also have a certain shock-absorbing effect. In addition, a first buffer portion 301, a second buffer portion 302 and a third buffer portion 303 which are superimposed on each other are formed on the buffer 30. It should be noted that the diameters of the first buffer portion 301, the second buffer portion 302 and the third buffer portion 303 gradually decrease in a step-like manner. The vibration of the self-priming actuator during movement is effectively offset by the buffer portions with different diameters, thereby improving the stability of the self-priming actuator during operation.

[0036] Preferably, the present solution further provides a raised block 31 for connecting the sheet metal on the mounting plate 3, and the shape of the raised block 31 can adopt various styles to achieve stable connection with connecting holes of different shapes on the sheet metal (not shown in the figure).

[0037] A limiting block 304 is further disposed at the end of the buffer member 30 , and the limiting block 304 and the third buffer portion 303 together form a buckle portion 300 .

[0038] Further, if Figures 1 to 3 As shown, the limit block 304 and the third buffer portion 303 together form a buckle portion 300. During the installation process, the buckle portion 300 can be used to slide into the left door lock buckle groove 10 or the right door lock buckle groove 11 (both are stepped groove designs) along the open end direction. When the third buffer portion 303 and the limit block 304 are respectively pressed against the two side walls of the buckle groove, a stable connection between the mounting plate 3 and the shell 1 can be achieved. It should be added that in the present solution, the shell 1 is composed of an upper shell 1 and a lower shell 1 that are detachably connected together by screws or bolts, and the left door lock buckle groove 10 and the right door lock buckle groove 11 are respectively installed at the periphery of the upper shell 1 and the lower shell 1, and both have a certain deformation ability, so that when the buckle portion 300 slides into the buckle groove, the buckle groove can rely on its own elastic deformation to lock the buckle portion 300 inside it, thereby improving the stability during installation.

[0039] A stepped hole 32 is formed at the periphery of the mounting plate 3, and a mounting block 33 is formed at the end of the buffer member 30 away from the limit block 304. The mounting block 33 and the first buffer portion 301 together form a connecting groove 34, and the bottom wall of the connecting groove 34 is interference fit with the inner wall of the stepped hole 32, so that the mounting block 33 and the first buffer portion 301 are respectively pressed against the two side walls of the mounting plate 3.

[0040] Similarly, when the first buffer portion 301, the second buffer portion 302 and the third buffer portion 303 pass through the stepped hole 32, the mounting block 33 and the first buffer portion 301 can respectively press against the two side walls of the mounting plate 3, as shown in FIG. Figure 3As shown, the inner wall of the stepped hole 32 is inserted into the connecting groove 34, and combined with the above-mentioned tight contact with the two side walls, it can not only limit the installation of the buffer 30, but also ensure that the buffer 30 as a whole is in a vertical state with the shell 1, thereby providing a guarantee for the subsequent shock-absorbing effect of the buffer 30 on the shell 1.

[0041] The transmission member 21 includes a coaxially arranged small gear 210 and a large gear 211 , wherein one group of large gears 211 is movably meshed with the output end of the transmission mechanism 2 , and the small gear 210 is movably meshed with the other group of large gears 211 .

[0042] The transmission member 21 in this embodiment is composed of two groups, and each group is composed of a coaxially arranged small gear 210 and a large gear 211. Figure 5 As shown, by utilizing the active meshing of the large gear 211 with the output end of the transmission mechanism 2, the coaxial small gear 210 is engaged with another set of large gears 211, thereby realizing multi-stage transmission of the gears, increasing the torque while effectively ensuring the stability of the self-priming wire drawing assembly 20 during movement.

[0043] Preferably, the transmission mechanism 2 in this solution also includes a driving member 22, such as Figure 4 and Figure 5 As shown, the output end of the driving member 22 is coaxially connected with a worm 23, and the worm 23 is movably engaged with the above-mentioned large gear 211. When the driving member 22 drives the worm 23 to rotate, it can drive the above-mentioned two sets of movably engaged small gears 210 and large gears 211 to drive the self-priming wire assembly 20 to move during the rotation process, so as to complete the pulling of the external self-priming pull rod.

[0044] The self-priming pull wire assembly 20 includes: an arc cam 200, which is rotatably arranged in the shell 1, and the arc cam 200 is movably engaged with a small gear 210 away from the worm 23; a self-priming pull wire 201, one end of which is connected to an external self-priming pull rod, and the other end is movably connected to the arc cam 200, so that when the arc cam 200 rotates, it can drive the self-priming pull wire 201 to move relative to the shell 1, so as to realize the self-priming action of the car door lock.

[0045] Further, if Figure 4 and Figure 5 As shown, the design of the arc cam 200 reduces the use of materials and reduces manufacturing costs. At the same time, the rotation of the arc cam 200 drives the movement of the self-priming pull wire 201, and finally the self-priming action of the door lock is realized when the self-priming pull rod is pulled. The overall structure is simple and compact, which saves the overall space occupied by the car door lock and is also conducive to improving the convenience of operation.

[0046] Preferably, continue to refer to Figure 4A waist-shaped groove 200a is also formed on the arc cam 200, and a connecting block 201a is formed at the end of the self-priming wire 201. The connecting block 201a is movably connected to the waist-shaped groove 200a, which effectively prevents the self-priming wire 201 from getting stuck as the arc cam 200 rotates, thereby ensuring the smoothness and stability of the self-priming action of the car door lock.

[0047] Preferably, the present solution further provides a detection switch 4 in the housing 1, and an arcuate surface 200b is formed on the arcuate cam 200. Figure 4 As shown, when the arc cam 200 is in the initial position, the detection switch 4 is pressed against the groove of the arc cam 200. Since the arc surface 200b and the groove are not in the same arc, as the arc cam 200 rotates, the detection switch 4 can detect the rotation angle of the arc cam 200 by pressing against the arc surface 200b, thereby realizing the detection of the moving distance of the self-priming pull wire 201 driving the self-priming pull rod.

[0048] It should be noted that the driving member 22 in this solution can be replaced by other driving devices such as a stepping motor, a servo motor, etc. In addition, for the automatic resetting of the self-absorption pull wire 201, other structures such as a torsion spring can be used to achieve it.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0051] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
