Description

Technical Field

[0001] The utility model relates to a motor wheel cover structure for a window regulator. Background Art

[0002] The motor wheel cover of a traditional window regulator does not have a buffer structure. The guide pipe adapted to the motor wheel cover is of a cylindrical structure, and there are round holes on the motor wheel cover. As the spring extends and then tightens, the guide pipe will hit the outlet of the motor wheel cover, posing a risk of generating abnormal noises.

[0003] Based on the above problems, we designed a motor wheel cover structure for a window regulator that can eliminate the abnormal noise caused by impacts. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a motor wheel cover structure for a window regulator that can eliminate the abnormal noise caused by impacts.

[0005] To solve the above problems, the utility model adopts the following technical solutions:

[0006] A motor wheel cover structure for a window regulator includes a wheel cover body. The wheel cover body has a cable channel for a cable, and both ends of the cable channel form openings for assembling the guide pipe. A buffer device is detachably installed in the openings.

[0007] Preferably, a plurality of convex portions are annularly distributed on the inner wall of the opening, and the buffer device is positioned by the convex portions.

[0008] Preferably, the buffer device includes an elastic washer. Concave holes for cooperating with the convex portions are provided on the outer wall of the washer. The washer fits the inner wall of the opening. A through hole for passing the cable is provided at the center of the washer, and the diameter of the through hole is larger than the diameter of the cable channel.

[0009] Preferably, a concave hole is provided at the top of the washer. The lower part of the concave hole is a counterbore, and the diameter of the counterbore is larger than the diameter of the concave hole. A buffer column is fitted through the concave hole. A snap ring portion is provided at the bottom of the buffer column. After elastic deformation, the snap ring portion passes through the concave hole and enters the counterbore, and the upper end of the buffer column is exposed outside the washer.

[0010] Preferably, a spring is embedded in the counterbore. The spring acts on the snap ring portion. Under the action of the spring, the snap ring portion acts on the stepped surface formed by the concave hole and the counterbore, and at this time, the upper end of the buffer column is located outside the washer.

[0011] Preferably, an exhaust hole is communicated between the through hole and the counterbore.

[0012] Preferably, a conical inner hole is provided inside the buffer column, and the inner hole penetrates downward.

[0013] Preferably, the upper end of the buffer column has a spherical transition.

[0014] The beneficial effects of the present utility model are as follows:

[0015] In this technical solution, by installing a buffer device inside the opening of the wheel housing body, when the guide tube impacts, the buffer device bears the impact force, avoiding abnormal noises, making it more silent in use, and alleviating the impact force of the guide tube, which has a protective effect on both the guide tube and the wheel housing body and is suitable for popularization and use.

[0026] Refer to Figure 1 A motor wheel cover structure for a window regulator shown in the figure, which includes a wheel cover body 1. The wheel cover body 1 has a cable passage 101 for a cable. Both ends of the cable passage 101 form an opening 102 for assembling a guide tube 2, and a buffer device 3 is detachably installed in the opening 102.

[0027] Refer to Figure 2 As shown in the figure, a plurality of convex portions 111 are annularly distributed on the inner wall of the opening 102, and the buffer device 3 is positioned by the convex portions 111.

[0028] By clamping the buffer device 3 with the convex portions 111, the detachment of the buffer device 3 can be avoided.

[0029] Refer to Figure 2 , Figure 3 and Figure 4 As shown in the figure, the buffer device 3 includes an elastic washer 31. A concave hole 32 for cooperating with the convex portion is provided on the outer wall of the washer 31. The washer 31 fits the inner wall of the opening 102. A through hole 33 for passing a cable is provided at the center of the washer 31, and the diameter of the through hole 33 is larger than the diameter of the cable passage 101.

[0030] In the above technical solution, through the elastic deformation of the washer 31, the convex portion 111 is snapped into the concave hole 32 to complete the positioning of the washer 31, and this structure facilitates the installation and removal of the washer 31.

[0031] Refer to Figure 3 and Figure 4 As shown, a concave hole 34 is provided at the top of the washer 31. The lower part of the concave hole 34 is a counterbore 35, and the diameter of the counterbore 35 is larger than that of the concave hole 34. A buffer column 36 is fitted through the concave hole 34. A retaining ring portion 37 is provided at the bottom of the buffer column 36. After elastic deformation, the retaining ring portion 37 passes through the concave hole 34 and enters the counterbore 35, and the upper end of the buffer column 36 is exposed outside the washer 31.

[0032] In the above technical solution, the buffer column 36 first contacts the guide tube 2, and then the guide tube 2 compresses the buffer column 36 before contacting the washer 31, achieving a double buffering effect, being quieter and having a better buffering effect.

[0033] Refer to Figure 3 As shown, a spring 331 is embedded in the counterbore 35. The spring 331 acts on the retaining ring portion 37. Under the action of the spring 331, the retaining ring portion 37 acts on the stepped surface formed by the concave hole and the counterbore, and at this time the upper end of the buffer column 36 is located outside the washer 31.

[0034] In the above technical solution, buffering and rebound after buffering are achieved through the cooperation of the spring 331 and the buffer column 36.

[0035] Refer to Figure 3 and Figure 4 As shown, an exhaust hole 399 communicates between the through hole and the counterbore.

[0036] The setting of the exhaust hole 399 is to prevent the air pressure in the counterbore 35 from affecting the downward movement of the buffer column 36, achieving an exhaust effect.

[0037] Refer to Figure 4 As shown, a tapered inner hole 366 is provided inside the buffer column 36, and the inner hole 366 penetrates downward.

[0038] The setting of the inner hole 366 facilitates the deformation of the buffer column 36.

[0039] The upper end of the buffer column 36 has a spherical transition.
