Description

Technical Field

[0001] The utility model belongs to the technical field of automobile locks, in particular to a waterproof structure of a suction driver. Background Art

[0002] With the development of the automotive industry and rising consumer spending, the use of self-priming door locks in passenger cars is increasing. These locks typically rely on a pull-in actuator to power the lock body and activate the lock. However, water droplets can occasionally enter the pull-in actuator through window gaps or connected actuators like exterior door handles during car washes or rainy days. This water intrusion can damage internal electrical components, causing the actuator to malfunction. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a waterproof structure of a suction driver, which utilizes a combination of sealing strips, compression ribs and waterproof rubber caps to achieve sealing and waterproofing, thereby effectively improving the waterproof performance of the suction driver.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a waterproof structure of an attraction driver, comprising:

[0005] A sealing strip is provided on the outer edge of the first housing of the driver and has a first open end and a second open end;

[0006] A compression rib is provided on the outer edge of the second housing of the driver and has a third open end and a fourth open end;

[0007] A waterproof rubber cap is provided at the cable output port formed by combining the first and second shells, and comprises a conical body covering the outer wall of the cable output port, a clamping rib at the end of the conical body, and a sealing section connected to the other end of the conical body;

[0008] The first open end, the second open end, the third open end and the fourth open end extend to a cable output port;

[0009] The sealing sleeve of the sealing section is arranged on the outer wall of the cable.

[0010] The utility model utilizes a combination of sealing strips, compression ribs and waterproof rubber caps to achieve good sealing performance of the entire suction drive, and the sealing section of the waterproof rubber cap is sealed on the outer wall of the cable to ensure the sealing performance of the cable position.

[0011] Furthermore, the snap-fit ​​rib seals the snap-fit ​​groove of the stretch output port, and the first, second, third, and fourth open ends extend beyond the snap-fit ​​groove. The waterproof rubber cap, the sealing strip, and the compression rib at least partially overlap to ensure the overall waterproof sealing performance of the pull-in actuator.

[0012] Furthermore, the sealing section includes a bellows section connected to the conical body and a contraction section connected to the bellows section. The contraction section has a minimum inner diameter that is smaller than the outer diameter of the cable. The bellows section is designed so that even if the cable moves to a certain extent, the contraction or expansion of the bellows section will not adversely affect the seal between the contraction section and the cable.

[0013] Furthermore, the cross section of the compression rib gradually decreases from the second shell toward the first shell, so that the cross section is trapezoidal.

[0014] Furthermore, the sealing strip is disposed within the groove of the first shell, and when the first shell and the second shell are assembled, the compression ribs are pressed against the end face of the sealing strip in an interference seal. The structural design of the sealing strip and the compression ribs ensures good sealing performance when the first shell and the second shell are assembled.

[0015] Furthermore, the opening width of the groove body is larger than the maximum width of the compression rib cross section, ensuring that the sealing strip forms a stable seal with the compression rib and also fits and seals with the inner walls of the second housing on both sides of the compression rib.

[0016] Furthermore, the sealing strip is made of elastic glue. When squeezed by the compression ribs, the deformed portion of the sealing strip can fill the groove, ensuring a sealed assembly of the two.

[0017] The beneficial effects of the present invention are: 1) the combination of the sealing strip, the compression rib and the waterproof rubber cap is used to achieve good sealing performance of the overall suction drive, and the sealing section of the waterproof rubber cap is sealed on the outer wall of the cable to ensure the sealing performance of the position where the cable is located; 2) the first open end, the second open end, the third open end and the fourth open end are at least partially overlapped with the waterproof rubber cap to avoid the problem of poor waterproof performance at the open ends of the sealing strip and the compression rib, and ensure the overall waterproof sealing performance of the suction drive; 3) the design of the waterproof rubber cap fits the shape of the cable output port, and has good sealing performance, and the design of the bellows section makes it possible that even if the cable moves to a certain extent, the contraction or extension of the bellows section will not have an adverse effect on the seal between the contraction section and the cable; 4) the structural design of the sealing strip and the compression rib ensures good sealing performance of the spliced ​​connection between the first shell and the second shell.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0027] like Figure 1-Figure 5 As shown, a waterproof structure of a suction driver includes a first shell 1 and a second shell 2. The waterproof structure includes a sealing strip 3 arranged on the outer edge of the first shell 1, a compression rib 4 arranged on the outer edge of the second shell 2, and a waterproof rubber cap 5.

[0028] The first and second shells 1 and 2 are assembled to form a cavity 12 for accommodating the transmission mechanism 8 and a cable output port 6 for extending the cable 7. The sealing strip 3 and the compression rib 4 are both located at the outer edge of the cavity 12, facing each other. The sealing strip 3 has a first open end 31 and a second open end 32, and the compression rib 4 has a third open end 41 and a fourth open end 42. These first, second, third, and fourth open ends 31, 32, 41, and 42 extend to the cable output port 6. A waterproof rubber cap 5 is provided over the cable output port 6.

[0029] like Figure 3As shown, the sealing strip 3 is disposed within the groove 11 of the first housing 1. The cross-sectional height of the sealing strip 3 is greater than the difference between the cross-sectional height of the groove 11 and the height of the compression rib 4. In this embodiment, the sealing strip 3 is a round strip of elastic rubber that is sealed into the groove 11. When squeezed by the compression rib 4, its deformed portion can fill the groove 11, ensuring a sealed assembly between the two. Of course, in other embodiments, continuous adhesive can be applied within the groove 11, and after the adhesive is formed, a sealing strip that can cooperate with the compression rib 4 is formed. This is not a specific limitation.

[0030] The cross-section of the compression rib 4 gradually decreases from the second shell 2 toward the first shell 1, resulting in a trapezoidal cross-section. Furthermore, the opening width of the groove 11 is greater than the maximum cross-sectional width of the compression rib 4. Therefore, when the first and second shells 1 and 2 are assembled, the compression rib 4 is entirely pressed against the sealing strip 3. The sealing strip 3 forms a stable seal with the compression rib 4 and also seals against the inner wall of the second shell 2 on both sides of the compression rib 4.

[0031] In order to ensure that the first shell 1 and the second shell 2 are tightly assembled, the first shell 1 and the second shell 2 are assembled in a locking manner using fasteners 13 , which are self-tapping screws.

[0032] like Figure 1 、 Figure 2 As shown, the waterproof rubber cap 5 comprises a conical body 51 covering the outer wall of the cable output port 6, a clamping rib 52 at the end of the conical body 51, and a sealing section 53 connected to the other end of the conical body 51. The shape of the conical body 51 is adapted to the shape of the cable output port 6, and both are trumpet-shaped, so that the inner and outer walls of the two fit together and seal. Figure 2 As shown, a snap-fit ​​groove 61 is formed at the cable output port 6. Specifically, the end portion of the frustum-shaped structure with a larger outer diameter is radially inwardly recessed to form the snap-fit ​​groove 61. The snap-fit ​​rib 52 of the waterproof rubber cap 5 is sealed and clamped in the snap-fit ​​groove 61. Figure 4 、 Figure 5 As shown, the first open end 31, the second open end 32, the third open end 41 and the fourth open end 42 extend beyond the engaging groove 61. In other words, as shown in FIG. Figure 2 As shown, the waterproof rubber cap 5, the sealing rubber strip 3 and the compression rib 4 are at least partially overlapped to ensure the waterproof sealing performance of the entire suction driver.

[0033] The sealing section 53 is provided on the outer wall of the cable 7. Figure 6 、 Figure 7As shown, the sealing section 53 includes a bellows section 531 connected to the conical body 51, and a contraction section 532 connected to the bellows section 531. The minimum inner diameter of the contraction section 532 is smaller than the outer diameter of the cable 7. Thus, while the contraction section 532 forms a stable seal with the cable 7, the bellows section 531 can also provide a certain sealing effect with the larger outer diameter portion of the cable 7. Furthermore, even if the cable 7 moves to a certain extent, the contraction or expansion of the bellows section 531 will not adversely affect the seal between the contraction section 532 and the cable 7.

[0034] The above specific implementation methods are used to illustrate the present invention rather than to limit the present invention. Any modifications and changes made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
