Description

Technical Field

[0001] This utility model relates to the field of glass lifter technology, and in particular to a waterproof and drainage structure for a glass lifter and a glass lifter. Background Technology

[0002] As a functional component of the car door interior, the main function of the window regulator is to ensure the smooth raising and lowering of the window glass, so that the doors and windows can be opened and closed smoothly at any time, and the glass can be stopped in any position without being affected by external forces or bumps in the car.

[0003] Currently, common window regulators are mainly divided into two types: single-arm and fork-arm. Single-arm window regulators (also known as coil-driven window regulators) have advantages such as simple structure, light weight, and small footprint. Driven by a motor assembly, they rotate a coil within a coil holder to wind a guide rope, thus moving the glass up and down on a guide plate to achieve the window's raising and lowering function.

[0004] During rain or car washes, water from the outside may splash, drip, or flow into the reel of the window regulator through the guide rope. If the temperature is below 0°C, this water may freeze inside the reel, forming ice and affecting the normal operation of the window regulator. In this case, the guide rope may freeze to the guide plate track or slip off during window regulator operation, causing the guide rope to derail and rendering the window regulator inoperable, thus preventing the window from raising or lowering. Utility Model Content

[0005] The main purpose of this utility model is to propose a waterproof and drainage structure for a glass lifter and a glass lifter in order to solve the problem of poor waterproof and drainage performance of existing glass lifters.

[0006] To achieve the above objectives, the waterproof and drainage structure of the glass lifter proposed in this utility model includes:

[0007] A drive assembly, the drive assembly including a drive element and a cover plate connected to each other;

[0008] A winding reel holder includes a fixed plate and a winding reel box. The winding reel box is mounted on the fixed plate and forms a receiving groove with one end open. A cover plate is placed over the opening. The receiving groove is used to place a winding reel. A drainage groove is provided on the side wall of the receiving groove. The drainage groove is located near the lower part of the fixed plate. A recess is also formed at the connection between the fixed plate and the winding reel box. The recess communicates with the drainage groove.

[0009] The guide rope and the fixing plate respectively form an inlet channel and an outlet channel that connect the receiving groove. The guide rope passes through the inlet channel and the outlet channel and is wound around the winding wheel.

[0010] A waterproof cap is provided, wherein a wire hole is provided, and a guide rope passes through the wire hole and is sleeved on the outside of the guide rope. The waterproof cap is positioned near the wire inlet of the wire inlet channel to cover the wire inlet of the wire inlet channel.

[0011] In one embodiment, the bottom wall of the drainage channel forms an inclined surface, which is inclined outward from the bottom wall of the receiving channel toward the opening of the receiving channel.

[0012] In one embodiment, the waterproof and drainage structure of the glass lifter further includes a waterproof cover, and the side wall of the receiving groove is provided with an oil injection hole. The oil injection hole is located near the top of the fixing plate. The waterproof cover is connected to the roller box, and the waterproof cover is provided corresponding to the oil injection hole and covers the oil injection hole.

[0013] In one embodiment, the waterproof cover is arched, one end of the waterproof cover is connected to the reel box, and the other end of the waterproof cover is bent away from the oil injection hole to form a guide section.

[0014] In one embodiment, the waterproof cap includes a water-blocking plate and a cap body. The water-blocking plate has the wire-passing hole. One end of the cap body is connected to the water-blocking plate, and the other end of the cap body covers the wire inlet of the wire inlet channel. The cap body is gradually widened in the direction away from the water-blocking plate. The guide rope passes through the water-blocking plate and the cap body in sequence and extends into the wire inlet of the wire inlet channel.

[0015] In one embodiment, the bottom wall of the receiving groove is further provided with a drain hole, which is located close to the drain groove.

[0016] In one embodiment, the cover plate is provided with a plurality of mounting ears at intervals along its circumference, and the fixing plate is provided with a plurality of first fixing holes, with the plurality of mounting ears corresponding one-to-one with the plurality of fixing holes.

[0017] In one embodiment, the fixing plate is provided with a plurality of second fixing holes spaced apart along its circumference, the second fixing holes being used for fixing to the door of the vehicle.

[0018] In one embodiment, the driving component and the cover plate are integrally formed components; the fixing plate and the winding box are integrally formed components.

[0019] This utility model also provides a glass lifter, which uses the above-mentioned waterproof and drainage structure.

[0020] In this invention, a drainage groove is provided on the side wall of the receiving groove, and the drainage groove is located on the side wall of the receiving groove near the lower part of the fixing plate. This allows water to flow out along the opening of the drainage groove due to gravity. To shorten the water flow distance in the receiving groove, a recess is provided at the connection between the fixing plate and the roller box. The recess communicates with the drainage groove. The recess reduces the height of the side wall of the receiving groove, allowing the water in the receiving groove to flow out more quickly, thus increasing the drainage performance of the glass lifter in this invention. By placing a waterproof cap over the guide rope and covering the inlet of the cable entry channel, and opening a cable passage hole on the waterproof cap so that the guide rope can pass through the cable passage hole, the cable passage hole can be interference-fitted with the guide rope. When water flows down the guide rope, the water flow is blocked at the cable passage hole of the waterproof cap, preventing the water from flowing directly into the receiving groove along the guide rope. Furthermore, by covering the cable entry channel with the waterproof cap, water can also be prevented from directly entering the receiving groove through the cable entry port, thus increasing the waterproof performance of the waterproof and drainage structure of the glass lifter in this utility model.

[0035] This utility model proposes a waterproof and drainage structure for a glass lifter and a glass lifter in general.

[0036] Please see Figures 1 to 4 In one embodiment of this utility model, the waterproof and drainage structure 100 of the glass lifter includes a drive assembly 1, a reel seat 2, a guide rope 3, and a waterproof cap 4. The drive assembly 1 includes a drive component 11 and a cover plate 12 connected to each other. The reel seat 2 includes a fixing plate 21 and a reel box 22. The reel box 22 is mounted on the fixing plate 21 and forms a receiving groove 221 with an opening 2211 at one end. The cover plate 12 covers the opening 2211. The receiving groove 221 is used to place the reel 222. A drainage groove 2212 is provided on the side wall of the receiving groove 221 to drain water. The water tank 2212 is located below the fixing plate 21. A recess 2213 is formed at the connection between the fixing plate 21 and the winding wheel box 22, and the recess 2213 is connected to the drainage tank 2212. The fixing plate 21 forms an inlet channel 31 and an outlet channel 32 that are connected to the receiving tank 221. The guide rope 3 passes through the inlet channel 31 and the outlet channel 32 and is wound around the winding wheel 222. The waterproof cap 4 has a wire hole 41. The guide rope 3 passes through the wire hole 41 and is sleeved on the outside of the guide rope 3. The waterproof cap 4 is located near the inlet of the inlet channel 31 to cover the inlet of the inlet channel 31.

[0037] In this embodiment, the driving component 11 can be an existing motor. A rotating shaft is provided on the cover plate 12, which covers the opening 2211. The rotating shaft on the cover plate 12 extends into the center of the winding wheel 222, so that the rotating shaft of the cover plate 12 is driven by the driving component 11 to drive the winding wheel 222 to rotate, thereby pulling the guide rope 3 to move through the winding wheel 222. The winding wheel seat 2 includes a fixing plate 21 and a winding wheel box 22. The fixing plate 21 is connected to the winding wheel box 22 and is used to fix it on the car door to fix the winding wheel box 22 firmly. The winding wheel box 22 forms a receiving groove 221, and the winding wheel 222 is disposed in the receiving groove 221. The fixing plate 21 forms an inlet channel 31 and an outlet channel 32 that communicate with the receiving groove 221, so that the guide rope 3 can pass through the inlet channel 31 and the outlet channel 32 and be wound on the winding wheel 222.

[0038] In the waterproof and drainage structure 100 of the glass lifter in the above embodiment, a drainage groove 2212 is provided on the side wall of the receiving groove 221. The drainage groove 2212 is located on the side wall of the receiving groove 221 near the bottom of the fixing plate 21, so that water can flow out along the opening of the drainage groove 2212 under the action of gravity. In order to shorten the water flow distance in the receiving groove 221, a recess 2213 is also provided at the connection between the fixing plate 21 and the roller box 22. The recess 2213 communicates with the drainage groove 2212. The setting of the recess 2213 reduces the height of the side wall of the receiving groove 221, so that the water in the receiving groove 221 can flow out faster, which increases the drainage performance of the glass lifter in this embodiment. Due to the setting of the inlet channel 31, external water Water may enter the receiving groove 221 through the inlet of the inlet channel 31 by attaching to the guide rope 3. In this embodiment, the waterproof cap 4 is sleeved over the guide rope 3 and covers the inlet of the inlet channel 31. A wire passage hole 41 is opened on the waterproof cap 4 so that the guide rope 3 can pass through the wire passage hole 41. The wire passage hole 41 can be interference-fitted with the guide rope 3. When water flows down the guide rope 3, the water flow is blocked at the wire passage hole 41 of the waterproof cap 4, which prevents the water flow from flowing directly into the receiving groove 221 along the guide rope 3. In addition, the waterproof cap 4 covers the inlet of the inlet channel 31, which can also prevent water from directly entering the receiving groove 221 through the inlet. This increases the waterproof performance of the waterproof and drainage structure 100 of the glass lifter in this embodiment.

[0039] In one embodiment, the bottom wall of the drainage trough 2212 forms an inclined surface 2212a, which is inclined outward from the bottom wall of the receiving trough 221 towards the opening 2211 of the receiving trough 2211. In this embodiment, the inclined surface 2212a on the bottom wall of the drainage trough 2212, which slopes outward from the bottom wall of the receiving trough 221 towards the opening 2211 of the receiving trough 221, effectively guides water flow and prevents water accumulation in the receiving trough 221. Simultaneously, the inclined surface 2212a helps improve drainage efficiency, ensuring that the reel 222 inside the receiving trough 221 always maintains good working condition and extends its service life.

[0040] In one embodiment, please refer to Figure 5 and Figure 6The waterproof and drainage structure 100 of the window regulator also includes a waterproof cover 5. An oil injection hole 6 is provided on the side wall of the receiving groove 221, located near the top of the fixing plate 21. The waterproof cover 5 is connected to the winding wheel box 22, and is positioned corresponding to and covering the oil injection hole 6. In this embodiment, the oil injection hole 6 allows the oiling device to add lubricating oil to the winding wheel 222 in the receiving groove 221, ensuring sufficient lubrication of the guide rope 3. The waterproof cover 5 is connected to the winding wheel box 22, ensuring its stable installation. The waterproof cover 5's alignment with the oil injection hole 6 effectively prevents water from entering the receiving groove 221 through the oil injection hole 6, thereby improving waterproof performance.

[0041] Based on the above embodiments, the waterproof cover 5 is arched, with one end connected to the roller box 22, and the other end bent away from the oil injection hole 6 to form a guide section 51. In this embodiment, the arched design of the waterproof cover 5 enhances its stability, and water located above the arch can flow more smoothly to the guide section 51. The connection of one end of the waterproof cover 5 to the roller box 22 and the bending of the other end away from the oil injection hole 6 to form the guide section 51 effectively guides rainwater or other water flow, further preventing water from flowing into the receiving groove 221 through the oil injection hole 6, thus further increasing the waterproof performance of the waterproof and drainage structure 100 of the glass lifter in this embodiment.

[0042] In one embodiment, please refer to Figure 7 The waterproof cap 4 includes a water-blocking plate 42 and a cap body 43. The water-blocking plate 42 has a wire-passing hole 41. One end of the cap body 43 is connected to the water-blocking plate 42, and the other end of the cap body 43 covers the wire inlet of the wire inlet channel 31. The cap body 43 is gradually widened in the direction away from the water-blocking plate 42. The guide rope 3 passes through the water-blocking plate 42 and the cap body 43 in sequence and extends into the wire inlet of the wire inlet channel 31. First, the water-blocking plate 42 effectively prevents water from entering the wire inlet channel 31, enhancing the overall waterproof performance. The size of the water-blocking plate 42 can be larger than the size of the wire inlet formed by the wire inlet channel 31. In addition, the gradually widening design of the cap body 43 improves the water guiding effect, ensuring that the water flow can be smoothly guided, thereby further reducing the risk of water flowing directly into the channel through the wire-passing hole 41. This further increases the waterproof capability of the waterproof and drainage structure 100 of the glass lifter.

[0043] In one embodiment, the bottom wall of the receiving tank 221 is further provided with a drain hole 2214, which is located close to the drain tank 2212. In this embodiment, the drain hole 2214 is provided on the bottom wall of the receiving tank 221, and the drain hole 2214 is located close to the drain tank 2212. Most of the water entering the receiving tank 221 can be discharged to the outside of the receiving tank 221 through the drain hole 2214, thereby reducing the drainage pressure of the drain tank 2212.

[0044] In one embodiment, the cover plate 12 is provided with a plurality of mounting ears 121 spaced apart along its circumference, and the fixing plate 21 has a plurality of first fixing holes 211, with each mounting ear 121 corresponding to one of the fixing holes. In this embodiment, the one-to-one correspondence between the plurality of mounting ears 121 and the plurality of first fixing holes 211 ensures that each mounting ear 121 can be installed in accordance with the fixing hole, effectively improving the connection strength and stability between the cover plate 12 and the fixing part. The evenly distributed mounting ears 121 help to evenly distribute the force, reducing the risk of deformation or damage caused by single-point force.

[0045] Based on the above embodiments, the fixing plate 21 is provided with a plurality of second fixing holes 212 at intervals along its circumference. The second fixing holes 212 are used for fixing to the car door. The second fixing holes 212 can be located close to the edge of the fixing plate 21, and the second fixing holes 212 can be installed on the car door by means of bolt connection, which is convenient for installation and disassembly.

[0046] In one embodiment, the drive component 11 and the cover plate 12 are integrally molded parts; the fixing plate 21 and the cable reel are integrally molded parts. In this embodiment, the integrally molded drive component 11 and cover plate 12, as well as the integrally molded fixing plate 21 and cable reel, are easy to manufacture, reduce the gap between components, help improve sealing performance, prevent dust and water intrusion, and increase their connection strength.
