Description

Technical Field

[0001] The utility model belongs to the component of an automobile window lifter, and particularly relates to a combined structure of a window lifter reel seat and a sleeve cap. Background Technique

[0002] As an important automobile component, the window lifter undertakes multiple functions, including adjusting the opening and closing degree of the automobile door and window, ensuring the smooth and stable lifting of the door glass, and enabling the glass to stay stably at any position when the lifter stops working. Through its design and functions, the window lifter not only improves the convenience of automobile use but also enhances the comfort and safety of passengers.

[0003] At present, most window lifters on the market adopt the rope-wheel type. As an important part of the window lifter, the winding seat mainly functions to fix the winding wheel and cooperate with the sleeve cap to provide support for the wire rope to exit. There is a gap between the sleeve cap 1 and the reel seat 2 used in the traditional double-rail window lifter, as Figure 5 shown, there is a play. When the lifter operates, the sleeve cap 1 collides with the reel seat 2, generating abnormal noises. In addition, after the motor is assembled with the reel seat 2, it will block the sleeve cap 1, making it impossible to confirm whether the sleeve cap 1 is installed in place. Summary of the Invention

[0004] The utility model provides a combined structure of a window lifter reel seat and a sleeve cap to solve the problems of a gap between the sleeve cap and the reel seat, play, abnormal noises generated, and inability to confirm whether the sleeve cap is installed in place.

[0005] The technical solution adopted by the utility model is that a boss is arranged in the sleeve cap connection port of the reel seat. The boss is in interference fit with the sleeve cap, and there is an observation hollow on the back of the reel seat inside the boss.

[0006] The sleeve cap includes a cap head and a tube body. The cap head is located in the sleeve cap interface, and their outer ends are flush. The tube body is in interference fit with the boss.

[0007] The sleeve cap is fixedly connected with the sleeve.

[0008] The advantages of the utility model are as follows: the structure is novel, which limits the collision between the sleeve cap and the reel seat, effectively avoids the generation of abnormal noises, and reduces customer complaints; the interference fit structure between the boss and the sleeve cap optimizes the connection mode between the sleeve cap and the reel seat, reduces part wear, improves the mechanical efficiency of the window lifter product itself, and increases the service life of the product; the observation hollow on the back is conducive to observing whether the sleeve cap is installed in place, and reduces the weight of the reel seat, saves materials, reduces costs, and improves the quality of the product.

[0014] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of description, only parts related to the present utility model rather than all structures are shown in the drawings.

[0015] As Figure 1 、 2 、and shown in Figure 3, a boss 4 is arranged in the sleeve cap connection port 201 of the reel seat 2. The boss 4 is in interference fit with the sleeve cap 1, and there is an observation hollow 5 on the back of the reel seat 2 inside the boss 4.

[0016] As Figure 2 、 4 shown, the sleeve cap 1 includes a cap head 101 and a tube body 102. The cap head 101 is located in the sleeve cap interface 201, and the outer ends of the two are aligned. The tube body 102 is in interference fit with the boss 4.

[0017] As Figure 1 、 2 shown, the sleeve cap 1 is fixedly connected to the sleeve 3.

[0018] Working principle

[0019] The sleeve cap 1 is in interference fit with the boss 4 of the reel seat 2. There is no gap between the sleeve cap 1 and the reel seat 2, which can limit the collision between the sleeve cap 1 and the reel seat 2, avoid abnormal noises, improve the user experience. At the same time, there is no relative movement between the sleeve cap 1 and the reel seat 2, which also reduces the wear of parts and increases the service life of the product; the observation hollow 5 on the back of the sleeve cap connection port of the reel seat is beneficial to observing whether the sleeve cap 1 is installed in place and reduces the weight of the reel seat, improving the quality of the product; shortening the length and reducing the diameter of the sleeve cap 1 can save materials and reduce costs.

[0020] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the protection scope of the present utility model is not limited to the specific details in the above embodiments. Within the technical concept of the present utility model, any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the technical concept of the present utility model, makes equivalent substitutions or changes, and these simple modifications all belong to the protection scope of the present utility model.
