Description

Technical Field

[0001] This utility model relates to the technical field of anti-worm gear toothed automotive window lift motors, specifically an anti-worm gear toothed automotive window lift motor. Background Technology

[0002] The automotive window regulator motor is the core power source of the automotive electric window system. Its core function is to convert electrical energy into mechanical energy to drive the window regulator mechanism and realize the "automatic raising and lowering" of the automotive window glass.

[0003] For example, a car window lift motor with announcement number "CN202475161U" has an output end connected to a drive device and an input end connected to a socket via wires. The socket has a side-mounted isolation plate screwed onto the motor's input end. To remove the socket, simply unscrew the isolation plate, greatly simplifying socket replacement. However, during operation, the motor vibrates when powered on. Since the motor's output shaft connects to a worm gear, and the worm only rotates at its top, the vibrations are transmitted to the worm gear, which in turn transmits the vibrations to the worm wheel. This can cause the worm wheel to disengage from the glass's toothed plate, resulting in worm wheel tooth creep and affecting the motor's normal operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem of worm gear creep in automotive window lift motors, which affects the normal use of the motors, and to propose an anti-worm gear creep automotive window lift motor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design an anti-worm gear tooth-climbing automotive window lift motor, including a first curved plate, an automotive window lift motor fixedly connected to the end of the first curved plate, a support structure connected to the front of the automotive window lift motor, a circular groove machined on the front of the automotive window lift motor, and a control structure connected to the lower outer wall of the automotive window lift motor.

[0006] Preferably, the support structure includes a circular block and a bent rod. The rear end face of the circular block is fixedly connected to the front shaft of the automotive window lifting motor. The left and right sides of the circular block are respectively fixedly connected to the inner sides of the two bent rods. A circular wheel is rotatably connected to the rear of the outer wall of the bent rod.

[0007] Preferably, the outer wall of the wheel is slidably connected to the inner wall of the groove.

[0008] Preferably, a gear is fixed to the front side of the circular block.

[0009] Preferably, a second curved plate is fixedly connected to the front right side of the automotive window lift motor.

[0010] Preferably, a wire is electrically connected to the lower outer wall of the automotive window lift motor.

[0011] Preferably, the control structure includes a bent plate and a bracket, the inner wall of the bent plate is inserted into the lower part of the outer wall of the automotive window lifting motor, the right side slot of the bent plate is inserted into the outer wall of the bracket, and a protective pad is fixed to the inner wall of the bracket.

[0012] Preferably, the inner wall of the pad is in contact with the outer wall of the wire.

[0013] The present invention proposes an anti-worm gear creep car window lift motor, the beneficial effects of which are as follows: A rotating circular block in the support structure drives a gear to rotate, which in turn moves the lifting glass tooth plate upwards, thereby lifting the car window. As the circular block rotates, it also drives a bent rod to rotate, which in turn drives a circular wheel to rotate on the inner wall of the circular groove. The cooperation between the bent rod and the circular wheel increases the support points of the circular block, thereby increasing the support points at the end of the worm gear behind the circular block. This effectively reduces the impact of motor vibration on the worm gear, preventing worm gear creep in the car window lift motor and ensuring its normal operation. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-6 In this embodiment, an anti-worm gear tooth automotive window lifting motor includes a first curved plate 1, an automotive window lifting motor 4 fixedly connected to the end of the first curved plate 1, a support structure 2 connected to the front of the automotive window lifting motor 4, a circular groove 6 machined on the front of the automotive window lifting motor 4, the model of the automotive window lifting motor 4 is BY-LD-01, and a control structure 3 connected to the lower outer wall of the automotive window lifting motor 4.

[0017] The support structure 2 includes a circular block 201 and a bent rod 202. The rear end face of the circular block 201 is fixedly connected to the front shaft of the car window lifting motor 4. The left and right sides of the circular block 201 are fixedly connected to the inner sides of the two bent rods 202 respectively. A circular wheel 203 is rotatably connected to the rear of the outer wall of the bent rod 202. The circular wheel 203 rotates through the bearing at the rear of the outer wall of the bent rod 202 under force. The outer wall of the circular wheel 203 is slidably connected to the inner wall of the circular groove 6. The circular wheel 203 slides along the trajectory through the inner wall of the circular groove 6 under force. A gear 7 is fixedly connected to the front of the circular block 201. The rotating circular block 201 in the support structure 2 drives the gear 7 to rotate. At this time, the gear 7 moves the lifting glass tooth plate upward, thereby raising the car window. When the circular block 201 rotates, it will drive the bent rod 202 to rotate. The rotating bent rod 202 drives the wheel 203 to rotate on the inner wall of the circular groove 6. At this time, the cooperation between the bent rod 202 and the wheel 203 increases the support points of the circular block 201, thereby increasing the support points at the end of the worm gear behind the circular block 201. This reduces the impact of motor vibration on the worm gear and prevents the worm gear from creeping, ensuring the normal operation of the car window lifting motor.

[0018] A second curved plate 5 is fixedly connected to the front right side of the car window lifting motor 4. A wire 8 is electrically connected to the lower outer wall of the car window lifting motor 4. The control structure 3 includes a curved plate 301 and a bracket 302. The inner wall of the curved plate 301 is inserted into the lower outer wall of the car window lifting motor 4. The right side slot of the curved plate 301 is inserted into the outer wall of the bracket 302. Bolts are threaded to the round openings of the outer walls of the curved plate 301 and the bracket 302. A protective pad 303 is fixedly connected to the inner wall of the bracket 302. The protective pad 303 is made of fluororubber, which protects the wire 8 and has good corrosion resistance and oxidation resistance. The inner wall of the protective pad 303 is in contact with the outer wall of the wire 8.

[0019] Working principle: Car window lift motor installation: Connect the top connector of wire 8 to the bottom interface of the car window lift motor 4. Then, wire 8 is aligned with the outer wall of the car window lift motor 4. Next, the inner wall of the bending plate 301 is connected to the outer wall of the car window lift motor 4 from left to right. Then, the bracket 302 is connected to the right side of the bracket 302 from right to left. At this time, the pad 303 on the inner wall of the bracket 302 is aligned with the outer wall of wire 8. Then, the bolt is threaded from right to left through the bracket 302 and connected to the round thread on the outer wall of the bending plate 301, thus fixing the outer wall of wire 8 and preventing the top of wire 8 from bending at the connection.

[0020] Next, the outer wall of gear 7 meshes with the lifting gear plate of the car window. At this time, the first curved plate 1 and the second curved plate 5 will fit against the car installation location. Then, the bolt passes through the first curved plate 1 and the second curved plate 5 and is threaded to the car connection location. Then, the other end of the wire 8 is plugged into the car body power interface to complete the power supply of the car window lifting motor 4.

[0021] How the car window lift motor works: When the car window lifting motor 4 is powered on, the internal motor output shaft drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel drives the circular block 201 on the front to rotate, and the rotating circular block 201 drives the gear 7 to rotate. At this time, the gear 7 drives the lifting glass plate to move upward, thereby lifting the car window. When the circular block 201 rotates, it also drives the bent rod 202 to rotate. The rotating bent rod 202 drives the circular wheel 203 to rotate on the inner wall of the circular groove 6. At this time, the cooperation between the bent rod 202 and the circular wheel 203 increases the support point of the circular block 201, which in turn increases the support point of the end of the worm wheel behind the circular block 201, thus mitigating the impact of motor vibration on the worm wheel.

[0022] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
