Drive mechanism for a glass lifter

Abstract

This utility model relates to a drive mechanism for a window regulator, belonging to automotive window regulator components. Wire rope one and wire rope two are respectively wound around a reel and have separate cable exits. The reel and reel seat are limited and rotatably connected by a snap-fit ​​mechanism. The reel seat has a drainage hole one, a drainage hole two, and an observation hole. The advantages are: novel structure; the separate cable exit mechanism of the reel seat effectively avoids abnormal noise between the wire ropes, reduces wear on parts, and thus reduces customer complaints; the observation hole in the reel seat facilitates observation of whether the reel is properly engaged, preventing the reel from detaching from the reel seat and improving product quality; the drainage outlet design at the wire rope routing point in the reel seat reduces the risk of parts corrosion and facilitates observation of whether the wire rope is tangled, increasing product lifespan.

Description

Technical Field

[0001] This utility model relates to automotive window regulator components, and more particularly to a drive mechanism for a window regulator. Background Technology

[0002] With the development of the automotive industry and the continuous improvement of consumer demands, automotive window regulators are no longer just simple functional components, but rather parts that directly affect user comfort, convenience, and the perceived quality of the vehicle. A typical window regulator consists of guide rails, window holders, a reel seat, a cable reel, a motor, cables, guide components, and a rotating wheel. The reel seat, cable reel, cables, and motor together form the drive mechanism. The reel seat's function is to fix the cable reel and, in conjunction with the sleeve cap, allow the wire rope to exit, thus achieving the function of raising and lowering the window.

[0003] The cable exit method of the traditional drive mechanism's reel seat is cross-type, such as... Figure 4 , 5 As shown, the gap between wire rope 3 and wire rope 4 allows for normal operation. However, due to space-saving design requirements, the thickness of the reel seat was reduced. This results in a smaller gap between wire rope 3 and wire rope 4 during operation, leading to overlap, abnormal noise, and wear on the wire ropes. Furthermore, the reel seat 1 lacks observation and drainage holes, increasing the risk of improper installation of the reel 2 and parts corrosion. Summary of the Invention

[0004] This utility model provides a drive mechanism for a glass lifter to solve the problems of easy splicing of steel wire ropes, abnormal noise and wear of steel wire ropes, and easy misinstallation of the winding wheel and corrosion of parts in cross-type cable reel seats.

[0005] The technical solution adopted by this utility model includes a reel seat, a winding reel, a first wire rope and a second wire rope, wherein the first wire rope and the second wire rope are respectively wound around the winding reel and are separately exited. The winding reel and the reel seat are limited and rotatably connected by a snap-fit ​​method. The reel seat has a first drainage hole, a second drainage hole and an observation hole.

[0006] The reel seat has a wire rope outlet 1 and a wire rope outlet 2. The joint ends of wire rope 1 and wire rope 2 are respectively clamped on the reel, and the other ends are discharged through wire rope outlet 1 and wire rope outlet 2. Wire rope 1 and wire rope 2 do not cross in the reel seat.

[0007] Drainage hole one and drainage hole two are respectively located on the body of the reel seat at the route of wire rope one and wire rope two.

[0008] The winding wheel seat is limited by the winding wheel seat boss and the winding wheel boss, and there is an observation hole behind the winding wheel seat boss.

[0009] The advantages of this utility model are its novel structure and the wire rope separation method of the reel seat, which can effectively avoid abnormal noise between wire ropes, reduce wear of parts, and thus reduce customer complaints; the addition of an observation hole in the reel seat makes it easy to observe whether the reel is properly engaged, preventing the reel from falling off the reel seat and improving product quality; the addition of a drainage outlet design at the wire rope routing point in the reel seat reduces the risk of parts corrosion and also makes it easy to observe whether the wire rope is tangled, increasing the product's service life.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0017] like Figure 1 , 2 As shown in Figure 3, the device includes a reel seat 1, a reel 2, a first wire rope 3, and a second wire rope 4. The first wire rope 3 and the second wire rope 4 are respectively wound around the reel 2 and are separately exited. The reel 2 and the reel seat 1 are limited and rotated by a snap-fit ​​connection. The reel seat 1 has a first drainage hole 103, a second drainage hole 104, and an observation hole 105.

[0018] like Figure 2As shown, the reel seat 1 has a wire rope outlet 101 and a wire rope outlet 102. The joint ends of wire rope 3 and wire rope 4 are respectively clamped on the reel 2, and the other ends are discharged through wire rope outlet 101 and wire rope outlet 102. Wire rope 3 and wire rope 4 do not cross in the reel seat 1.

[0019] like Figure 2 As shown, the main body of the reel seat 1 at the wire rope 3 and wire rope 4 has drainage hole 103 and drainage hole 2104 respectively.

[0020] like Figure 3 As shown, the winding wheel seat 1 is limited by the winding wheel seat boss 106 and the winding wheel boss 201, and there is an observation hole 105 behind the winding wheel seat boss 106. It is used to observe the connection between the winding wheel seat 1 and the winding wheel 2.

[0021] Working principle:

[0022] The cross-out structure of the two wire ropes is changed to a separate outgoing structure. This type of reel seat outgoing structure can prevent wire rope one and wire rope two from overlapping, avoid friction and abnormal noise, and also reduce wear between the two wire ropes, thus extending the product's service life.

[0023] Drainage holes 103 and 104 are added at the wire rope routing point on the reel seat to reduce the risk of parts corrosion and make it easier to observe whether the wire rope is tangled.

[0024] The observation hole 105 allows for easy observation of whether the winding reel 2 is installed in place.

[0025] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the scope of protection of the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, any equivalent substitutions or modifications made by those skilled in the art based on the technical solution and the inventive concept of the present invention within the scope of the technical concept disclosed in the present invention shall all fall within the scope of protection of the present invention.

[0026] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
