Description

Technical Field

[0001] This utility model relates to the field of automotive window motor technology, specifically to a vibration damping module for a car window lifting motor. Background Technology

[0002] The door system is one of the most complex systems on a car body. The door window lifting system involves many parts. When the window lifting motor is working, it will generate vibration, which will cause noise. In order to improve the quality of the car, a vibration reduction module for the window lifting motor has been proposed.

[0003] The patent application with publication number CN211818900U, publication date October 30, 2020, entitled "Vehicle Window Lifting Motor Vibration Damping Module and Automobile," includes a vehicle window lifting motor, a vibration damping pad, and a vehicle window lifter. The vehicle window lifting motor includes a power unit for generating rotational kinetic energy and an output unit for outputting rotational kinetic energy. The output unit is fixedly connected to the vehicle window lifter and transmits the rotational kinetic energy generated by the power unit to the vehicle window lifter. The vibration damping pad is disposed between the power unit and the vehicle window lifter to absorb the vibration energy of the power unit and reduce vibration noise. The automobile provided by this utility model has the above-mentioned vehicle window lifting motor vibration damping module in the vehicle window lifting system, which can reduce the vibration noise of the vehicle window lifting system. It is simple, effective, low-cost, and does not affect the vehicle development cycle.

[0004] Existing window regulator motor vibration damping modules place damping pads between the power unit and the window regulator to prevent the motor from transmitting vibrations to the window regulator. However, it has been found that the window regulator motor requires transmission via a worm gear and worm shaft, and the motor and worm shaft are fixedly connected. This causes the motor to transmit vibrations to the worm shaft, resulting in vibrations in the worm shaft and noise from the worm gear, making it inconvenient to use. Therefore, we have proposed a window regulator motor vibration damping module to solve the problems mentioned above. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] The purpose of this utility model is to provide a vibration damping module for a car window lift motor to solve the problems currently found in the market as described in the background.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping module for a car window lift motor, comprising a vehicle frame, a lift motor mounted on one side of the vehicle frame, and a rubber pad installed between the lift motor and the vehicle frame, wherein...

[0009] A worm gear is rotatably connected to one side of the frame corresponding to the lifting motor, and a worm is rotatably connected to the outer side of the frame corresponding to the worm gear. The shaft end of the lifting motor is connected to the worm through a vibration damping drive shaft, and both ends of the vibration damping drive shaft are fixedly connected to the shaft end of the lifting motor and the worm through flanges.

[0010] Preferably, a spool is mounted on the shaft end of the worm gear.

[0011] Preferably, the pitch of the worm helix is ​​equal to the pitch of the worm wheel, and the worm and the worm wheel mesh with each other.

[0012] Preferably, the vibration damping drive shaft is formed by alternating stacking of metal sheets and rubber sheets, with slots symmetrically passing through the metal sheets and rubber sheets, and a rubber rod passing through the slot.

[0013] Preferably, the outer diameters of the metal sheet and the rubber sheet are equal, the slot positions of the metal sheet and the rubber sheet correspond one-to-one, and the metal sheet and the rubber sheet are fixedly connected by adhesive bonding.

[0014] Preferably, the rubber rod is a cylinder, and the outer diameter of the rubber rod matches the inner diameter of the slot.

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the vibration damping module for the car window lift motor of this utility model has the following specific details:

[0017] (1) The lifting motor forms a flexible connection between the frame and the worm gear through rubber pads and vibration damping drive shaft. When the window needs to be raised and lowered, the lifting motor will vibrate. The vibration is damped by the rubber pads and vibration damping drive shaft, which prevents the lifting motor from transmitting the vibration force to the frame and the worm gear. This effectively reduces the noise generated by the vibration when the lifting motor is working, and further improves the quietness of the lifting motor when it is working.

[0018] (2) When the lifting motor is working, it drives the worm gear to rotate through the vibration damping drive shaft. The vibration damping drive shaft is formed by alternating superposition of metal sheets and rubber sheets, and the rubber rod is inserted into the slot. The rubber rod supports the connection between the metal sheets and the rubber sheets, so that the vibration damping drive shaft has a vibration damping effect while ensuring the axial rigidity of the vibration damping drive shaft. This allows the lifting motor to carry out stable transmission through the vibration damping drive shaft and avoids the vibration damping drive shaft itself from twisting.

[0027] Please see Figures 1 to 3A vibration damping module for a car window lift motor includes a vehicle frame 1, a lift motor 2 mounted on one side of the vehicle frame 1, and a rubber pad 3 installed between the lift motor 2 and the vehicle frame 1.

[0028] A worm gear 4 is rotatably connected to one side of the frame 1 corresponding to the lifting motor 2, and a worm 6 is rotatably connected to the outer side of the frame 1 corresponding to the worm gear 4. The shaft end of the lifting motor 2 is connected to the worm 6 through a vibration damping transmission shaft 7, and both ends of the vibration damping transmission shaft 7 are fixedly connected to the shaft end of the lifting motor 2 and the worm 6 through flanges 8.

[0029] The lifting motor 2 is flexibly connected to the frame 1 and the worm gear 6 via the rubber pad 3 and the vibration damping drive shaft 7. When the window needs to be raised or lowered, the lifting motor 2 vibrates. The vibration is damped by the rubber pad 3 and the vibration damping drive shaft 7, which prevents the lifting motor 2 from transmitting the vibration force to the frame 1 and the worm gear 6. This effectively reduces the noise generated by the vibration when the lifting motor 2 is working, and further improves the quietness of the lifting motor 2 when it is working.

[0030] Please see Figures 1 to 3 A worm wheel 4 has a worm reel 5 mounted on its shaft end. The pitch of the worm 6 helical teeth is equal to the pitch of the worm wheel 4, and the worm 6 and the worm wheel 4 mesh with each other.

[0031] Please see Figures 1 to 3 The vibration damping drive shaft 7 is formed by alternating stacking of metal sheets 9 and rubber sheets 10. Slots 11 symmetrically penetrate the metal sheets 9 and rubber sheets 10, and rubber rods 12 pass through the slots 11. The outer diameters of the metal sheets 9 and rubber sheets 10 are equal, and the positions of the slots 11 on the metal sheets 9 and rubber sheets 10 correspond one-to-one. The metal sheets 9 and rubber sheets 10 are fixedly connected by adhesive bonding. The rubber rod 12 is cylindrical, and its outer diameter matches the inner diameter of the slot 11. When the lifting motor 2 is working, the vibration damping drive shaft 7 drives the worm gear 6 to rotate. The vibration damping drive shaft 7, formed by alternating stacking of metal sheets 9 and rubber sheets 10, with the rubber rods 12 inserted into the slots 11, supports the connection between the metal sheets 9 and rubber sheets 10. This ensures that the vibration damping drive shaft 7 has a vibration damping effect while maintaining its axial rigidity, allowing the lifting motor 2 to achieve stable transmission through the vibration damping drive shaft 7 and preventing the vibration damping drive shaft 7 from twisting.

[0032] Working principle: When using this window lift motor vibration damping module, if... Figures 1 to 3As shown, firstly, the lifting motor 2 is flexibly connected to the frame 1 and the worm gear 6 via the rubber pad 3 and the vibration damping drive shaft 7. When the window needs to be raised or lowered, the lifting motor 2 vibrates during operation. The vibration is damped by the rubber pad 3 and the vibration damping drive shaft 7, preventing the lifting motor 2 from transmitting the vibration force to the frame 1 and the worm gear 6. This effectively reduces the noise generated by the vibration of the lifting motor 2 during operation, further improving the quietness of the lifting motor 2. When the lifting motor 2 is working, it drives the worm gear 6 to rotate through the vibration damping drive shaft 7. The vibration damping drive shaft 7 is formed by alternating layers of metal sheet 9 and rubber sheet 10, with a rubber rod 12 inserted into the slot 11. The rubber rod 12 supports the connection between the metal sheet 9 and the rubber sheet 10, ensuring that the vibration damping drive shaft 7 has a vibration damping effect while maintaining the axial rigidity of the vibration damping drive shaft 7. This allows the lifting motor 2 to transmit power stably through the vibration damping drive shaft 7, preventing the vibration damping drive shaft 7 itself from twisting.
