Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass lift technology, and in particular to a glass lift motor protection device, a glass lift assembly, and a vehicle. Background Technology
[0002] Automotive window regulators are devices used to automatically raise and lower vehicle windows. An electric motor drives a winding wheel to rotate a steel cable, causing a slider fixed to the outside of the cable to move up and down, thus raising and lowering the car window. Existing window regulators, to prevent hands from being pinched, incorporate control equipment that detects the motor's current. Changes in current are used to determine if the resistance exceeds a threshold, triggering anti-pinch protection and achieving adaptive resistance adjustment.
[0003] Motors generate heat during use. To improve heat dissipation, holes are made on the outside of the motor. However, since the motor is installed inside the car door, rainwater can seep into the door through gaps during rainy or snowy weather. This water then drips onto the outer surface of the motor and enters the motor through the heat dissipation holes, causing corrosion to the rotor and other components inside the motor. This accelerates motor damage and reduces its lifespan. Utility Model Content

Detailed Implementation
[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] In related technologies, motors generate heat during use. To improve heat dissipation, holes are made on the outside of the motor. However, since the motor is installed inside the car door, rainwater can seep into the door through gaps during rainy or snowy weather. This water then drips onto the outer surface of the motor and enters the motor through the heat dissipation holes, causing corrosion to the rotor and other components inside the motor. This accelerates the damage to the motor and affects its lifespan.
[0031] In view of this, such as Figures 1-6 As shown in some embodiments of this utility model, a protective device for a glass lifting motor 11 is provided for waterproofing the lifting motor 11. The lifting motor 11 is mounted on a bracket. The protective device for the glass lifting motor includes a protective cover 1 and a shield 2. The protective cover 1 is connected to the bracket and covers the lifting motor 11. The protective cover 1 is provided with a plurality of heat dissipation holes 4, which penetrate the side wall of the protective cover 1. The shield 2 is connected to the protective cover 1 and is located on the side of the protective cover 1 away from the lifting motor 11. The shield 2 is used to block the heat dissipation holes 4 to prevent liquid from entering the protective cover 1 through the heat dissipation holes 4.
[0032] In the above embodiments, the protective cover 1 and the shield 2 can be integrally molded by injection molding or welded together. Both the protective cover 1 and the shield 2 can be made of plastic or a heat-conducting metal material, such as aluminum alloy. The lifting motor 11 can be vertically fixed to the upper surface of the bracket, which can be horizontally set. The bracket can be made of metal or plastic. One side of the protective cover 1 has an opening, and the protective cover 1 is fastened to the lifting motor 11 through the opening, so that the protective cover 1 abuts against the upper surface of the bracket and is connected. Thus, the protective cover 1 can protect the lifting motor 11 and prevent water droplets falling from above from contacting the lifting motor 11 and causing damage to the lifting motor 11. The protective cover 1 can be connected to the bracket by welding, bonding or bolting. Furthermore, multiple heat dissipation holes 4 can be provided on the side wall of the protective cover 1. The heat dissipation holes 4 can be circular or elongated and extend horizontally. Three heat dissipation holes 4 are provided on each side along the height direction of the protective cover 1. At the same time, the heat dissipation holes 4 on both sides are symmetrically arranged, so that the heat dissipation holes 4 on both sides can form a heat dissipation channel, increasing the heat dissipation efficiency of the lifting motor 11. A shield 2 is provided on each heat dissipation hole 4. The shield 2 can be connected to the side of the heat dissipation hole 4 away from the bracket. The shield 2 is used to prevent water droplets falling from above from entering the heat dissipation hole 4, thereby avoiding damage to the lifting motor 11.
[0033] Optionally, the heat dissipation hole 4 can be set at an angle, the axis of the heat dissipation hole 4 can be set at an angle with the axis of the lifting motor 11, and the heat dissipation hole 4 can be set downward, so as to prevent liquid from entering the heat dissipation hole 4.
[0034] The liquid can be rainwater, beverages, or other liquids that may damage the lifting motor 11.
[0035] Some embodiments of this utility model provide a protective device for a glass lift motor 11, used for waterproofing the lift motor 11. The lift motor 11 is mounted on a bracket and includes a protective cover 1 and a shield 2. The protective cover 1 is connected to the bracket and covers the lift motor 11. The protective cover 1 is provided with multiple heat dissipation holes 4, which penetrate the side wall of the protective cover 1. The shield 2 is connected to the protective cover 1 and is located on the side of the protective cover 1 away from the lift motor 11. The shield 2 is used to block the heat dissipation holes 4, preventing liquid from entering the protective cover 1 through the heat dissipation holes 4. This effectively prevents the lift motor 11 from coming into contact with liquid and causing a short circuit, solving the technical problem of rainwater entering the motor and causing damage in the prior art, and achieving the technical effect of the lift motor 11 being less prone to damage and having a long service life.
[0036] In an optional embodiment, a mounting foot 5 is provided on each side of the protective cover 1, and two fastening blocks 6 are provided on the bracket. Each fastening block 6 is engaged with a mounting foot 5 to connect the protective cover 1 to the bracket.
[0037] In an optional embodiment, a slot is provided on the mounting foot 5, the slot is provided through the mounting foot 5, and the fastening block 6 is inserted into the slot so that the mounting foot 5 is connected to the fastening block 6.
[0038] In the above embodiment, the mounting feet 5 can be integrally formed with the protective cover 1. The mounting feet 5 can be respectively set on the two opposite sides of the protective cover 1, with the two mounting feet 5 set on the same plane and symmetrically arranged. Two fastening blocks 6 are vertically arranged on the bracket, each fastening block 6 corresponding to one mounting foot 5. Each fastening block 6 is provided with a wedge, and each mounting foot 5 is provided with a slot. The cross-section of the slot can be rectangular. As the protective cover 1 approaches the bracket, the two mounting feet 5 on the protective cover 1 first contact the wedges of the two fastening blocks 6. The inner walls of the two slots begin to squeeze the two wedges, causing the two fastening blocks 6 to begin to deform. Then, after the wedges pass through the slots, the two fastening blocks 6 return to their original shape, so that the mounting feet 5 and the fastening blocks 6 are engaged, thereby fixing the protective cover 1.
[0039] In an optional embodiment, the distance between the shield 2 and the heat dissipation hole 4 is set to increase gradually along the direction of liquid flow.
[0040] In the above embodiment, the shield 2 is disposed on the side of the heat dissipation hole 4 away from the bracket and extends obliquely towards the bracket, so that the distance between the shield 2 and the opening of the heat dissipation hole 4 increases along the direction towards the bracket, so that when the liquid falls, the liquid can pass through the shield 2 away from the heat dissipation hole 4, and prevent the liquid from entering the protective cover 1 through the heat dissipation hole 4.
[0041] In an optional embodiment, a heat-absorbing component 3 is also included. The heat-absorbing component 3 is disposed on the inner wall of the protective cover 1 where the heat dissipation holes 4 are not opened. The heat-absorbing component 3 is used to absorb the heat emitted by the lifting motor 11.
[0042] In the above embodiments, the heat-absorbing component 3 can be fixed on the inner wall of the protective cover 1. The heat-absorbing component 3 can be set away from the bracket, so that the heat-absorbing component 3 can absorb the heat emitted by the lifting motor 11 inside the protective cover 1, and avoid the lifting motor 11 from overheating and being damaged. Furthermore, the protective cover 1 can be made of aluminum alloy, so that the heat-absorbing component 3 can effectively use the protective cover 1 for heat dissipation.
[0043] In an optional embodiment, the heat absorption assembly 3 includes a loading plate 301 and a heat absorber 302. The heat absorber 302 is installed on the side of the loading plate 301 near the lifting motor 11. A connector is provided on the side of the loading plate 301 away from the lifting motor 11.

[0044] In an optional embodiment, a chamber is provided inside the loading plate 301, and the heat absorber 302 includes paraffin wax, which is sealed and installed inside the chamber.
[0045] In the above embodiment, the loading plate 301 can be made of a metal material that is easy to conduct heat. The loading plate 301 can be provided with a chamber for fixing the heat absorber 302. The heat absorber 302 can be made of paraffin wax. The heat absorber 302 can be poured into the chamber so that the heat absorber 302 is connected to the loading plate 301. The paraffin wax can be used to absorb heat, and then the heat is dissipated through the loading plate 301 and the protective cover 1, thereby improving the heat dissipation efficiency in the protective cover 1.
[0046] One side of the chamber may have an opening, and a rubber plug may be provided at the opening. The rubber plug can seal the chamber for the replacement of the heat absorber 302. Alternatively, the loading plate 301 may be connected to the heat absorber 302. When the heat absorption efficiency of the heat absorber 302 decreases, the loading plate 301 and the heat absorber 302 may be replaced at the same time. The heat absorber 302 may also include a rock wool board.
[0047] In an optional embodiment, the connector includes a first Velcro 7 and a second Velcro 8. The first Velcro 7 is fixedly connected to the loading plate 301, and the second Velcro 8 is fixedly connected to the protective cover 1. The first Velcro 7 and the second Velcro 8 are bonded together.
[0048] In the above embodiment, the shape and size of the first hook and loop fastener 7 and the second hook and loop fastener 8 can be the same. One side of the first hook and loop fastener 7 can be fixed to the side of the loading plate 301 away from the bracket by adhesive. The second hook and loop fastener 8 can be fixed to the inner wall of the protective cover 1 by adhesive. By bonding the first hook and loop fastener 7 and the second hook and loop fastener 8, the loading plate 301 can be quickly fixed. At the same time, by separating the first hook and loop fastener 7 and the second hook and loop fastener 8, the loading plate 301 can be removed, making it easier to replace the loading plate 301.
