Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a rear-wheel drive double-peak dust cover. Background Technology

[0002] The rear-wheel drive dust cover is a protective device installed at the gear shift lever position of a car to prevent dust and other contaminants from entering and affecting the normal shifting of gears. Under the current technology, common rear-wheel drive dust covers are single-peak dust covers and multi-peak dust covers. Single-peak dust covers are small in size and lightweight, while multi-peak dust covers have a larger limit swing angle when in use. Both types of dust covers have certain disadvantages. Therefore, the applicant provides a rear-wheel drive double-peak dust cover. Utility Model Content

[0003] To address the issue that existing rear-drive dust covers commonly come in single-peak and multi-peak designs, with single-peak dust covers being small and lightweight while multi-peak dust covers have a larger maximum swing angle during use, and both types of dust covers have certain drawbacks, the applicant proposes a rear-drive dual-peak dust cover, the specific solution of which is as follows.

[0004] A rear-wheel drive dual-peak dust cover includes a cover body. One end of the cover body is provided with a mating hole for mating with a gear shift seat. The other end of the cover body is provided with a positioning hole for the vehicle's gear shift lever to extend into. The cross-sectional area of ​​the mating hole is larger than that of the positioning hole. The cover body has two protruding peak segments that surround the circumference of the cover body and are spaced apart along the vertical direction of the cover body.

[0005] By adopting the above technical solution and setting two wave crests, the volume is greatly reduced compared to multi-crest dust covers, making them lighter and significantly reducing the amount of grease used. Compared to single-crest dust covers, the extreme swing angle is increased, combining multiple advantages and overcoming the two problems of the original dust covers.

[0006] Optionally, the cross-section of the crest segment is cone-shaped.

[0007] By adopting the above technical solution, the cone-shaped wave crests can precisely correspond to the force generated when the shift lever swings, improving the overall flexibility of the cover and effectively enhancing the cushioning effect.

[0008] Optionally, the distance from the cone apex to the axis of the cover of the wave crest located on the upper side of the cover is less than the distance from the cone apex to the axis of the cover of the wave crest located on the lower side of the cover.

[0009] By adopting the above technical solutions, the distance from the top of the cone to the axis of the cover is made smaller than the distance from the top of the cone to the axis of the cover. This optimizes the spatial layout and stress distribution of the dust cover, further improving its durability and practicality during the gear shifting process of a car.

[0010] Optionally, the outer wall of the cover is provided with a mounting ring groove, which is positioned corresponding to the mating hole, and the mounting ring groove is used to install a clamp.

[0011] By adopting the above technical solution, a mounting ring groove is set on the outer wall of the cover at the corresponding mating hole position and a clamp is installed, which can better fix the dust cover and the shift seat and prevent dust and other objects from entering and affecting the normal shifting of the car.

[0012] Optionally, the outer wall of the cover is also provided with a mounting ring groove corresponding to the positioning hole, and the mounting ring groove at the positioning hole is also used to install the clamp.

[0013] By adopting the above technical solution, an installation ring groove is also set at the corresponding positioning hole on the outer wall of the cover for installing clamps, which can further fix the connection between the cover and the shift lever, and ensure the stability of the rear-drive double-peak dust cover.

[0014] Optionally, a retaining edge is provided on one side of the mounting ring groove. The retaining edge protrudes from the cover and is equidistantly spaced along the circumference of the cover. The retaining edge is used to abut against the clamp.

[0015] By adopting the above technical solution, a retaining clamp with equal intervals along the circumference of the cover is set on one side of the installation ring groove, which restricts the displacement and slippage of the clamp, reduces the possibility of the clamp falling out of the installation ring groove, and ensures installation stability.

[0016] Optionally, the retaining edge is arranged in an arc shape.

[0017] By adopting the above technical solution and making the edge curved, the coverage area can be increased to a certain extent. Even if there is some displacement, it can still fit with the clamp, which can better fit the clamp, enhance the resistance effect of the clamp, ensure the clamp is installed stably, make the rear drive double wave peak dust cover more secure, and can better interfere with the clamp when it falls off, further reducing the chance of falling off.

[0018] Optionally, a limiting protrusion is provided on the side of the mounting ring groove away from the retaining edge. The limiting protrusion is positioned corresponding to the position of the retaining plate and is also used to abut against the clamp.

[0019] By adopting the above technical solution, the limiting protrusion set on the side of the installation ring groove away from the flange corresponding to the baffle position abuts the clamp, which can further enhance the stability and reliability of the clamp installation and better fix the dust cover.

[0020] Optionally, the cover body is further provided with a snap-fit ​​groove at the mounting ring groove, the snap-fit ​​groove being deeper than the mounting ring groove, and the snap-fit ​​groove being used to embed a clamp.

[0021] By adopting the above technical solutions, the snap-fit ​​groove can facilitate the installation of the clamp, further improve the stability of the clamp installation, and reduce the occurrence of clamp detachment.

[0022] In summary, this application has at least the following beneficial effects: This application addresses the problem that existing rear-drive dust covers commonly include single-peak and multi-peak dust covers. Single-peak dust covers are small and lightweight, while multi-peak dust covers have a larger maximum swing angle during use. Both types of dust covers have certain drawbacks. This application solves the problem by setting two sets of peak segments, which not only makes the dust cover lighter and reduces the use of grease, but also increases the maximum swing angle of the dust cover. It combines the advantages of the two types of dust covers in the prior art and can be used in more application environments. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] A rear-drive dual-wave dust cover, such as Figure 1 and Figure 2 As shown, the device includes a cover 1. One end of the cover 1 has a mating hole 2 for mating with a gear shift seat, and the other end has a positioning hole 3 for inserting the gear shift lever. The cross-sectional area of ​​the mating hole 2 is larger than that of the positioning hole 3. The cover 1 has two protruding wave crests 4, which are arranged circumferentially around the cover 1 and spaced apart along the vertical direction of the cover 1. In practice, using two wave crests 4 makes the dust cover lighter than a multi-crest dust cover. Since grease needs to be applied to the inner wall of each crest, the more crests there are, the more grease is needed. Therefore, the amount of grease used is greatly reduced when using two crests. Compared to a single-crest dust cover, the double crests have the same effect as multi-crests, both increasing the limit angle of rotation. During installation, the mating hole 2 is positioned corresponding to the gear shift seat, and the gear shift lever is inserted into and fixed in the positioning hole 3. The entire cover 1 is formed by rubber injection molding and has a certain degree of elasticity.

[0029] like Figure 1 As shown, the cross-section of wave crest segment 4 is cone-shaped. The distance from the cone apex to the axis of the cover 1 of the wave crest located on the upper side of the cover 1 is smaller than the distance from the cone apex to the axis of the cover 1 of the wave crest located on the lower side of the cover 1. In practice, the wave crest segment 4 closer to the handball is smaller, which better matches the force distribution during use.

[0030] like Figure 1 and Figure 3 As shown, the outer wall of the cover 1 is provided with a mounting ring groove 5, which is positioned corresponding to the mating hole 2, and is used to install a clamp. The outer wall of the cover 1 is also provided with a mounting ring groove 5 corresponding to the positioning hole 3, and the mounting ring groove 5 at the positioning hole 3 is also used to install a clamp. In specific implementation, the clamp at the bottom of the cover 1 can be connected to the shift seat, while the clamp at the top of the cover 1 can be fixed to the shift lever.

[0031] like Figure 1 and Figure 3 As shown, a retaining edge 6 is provided on one side of the mounting groove 5. The retaining edge 6 protrudes from the cover 1 and is evenly spaced along the circumference of the cover 1. The retaining edge 6 is used to abut against the clamp. In specific implementation, as follows: Figure 2 As shown, the retaining edge 6 is arc-shaped and is also made of rubber injection molding. It has a certain elasticity when it is removed and has a large friction force, which can limit the displacement and slippage of the clamp and improve stability.

[0032] like Figure 1 and Figure 3 As shown, a limiting protrusion 7 is also provided on the side of the mounting groove 5 away from the retaining edge 6. The limiting protrusion 7 is positioned corresponding to the position of the retaining plate and is also used to abut against the clamp. In actual implementation, the limiting protrusion 7 and the retaining edge 6 can simultaneously restrict the clamp from both sides, further reducing the possibility of the clamp falling off.

[0033] like Figure 1 and Figure 3 As shown, the cover 1 also has a snap-fit ​​groove 8 at the mounting ring groove 5. The snap-fit ​​groove 8 is deeper than the mounting ring groove 5 and is used to embed the clamp. In specific implementations, the snap-fit ​​groove 8 can be set to correspond to different shapes of the clamp, thereby further restricting the clamp.

[0034] Working principle: It features a dual-peak design, combining the advantages of traditional single-peak and multi-peak dust covers, effectively integrating the strengths of both, and making it suitable for a wider range of applications.

[0035] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
