Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an electric tailgate drive gearbox housing with integrated PCBA board. Background Technology

[0002] A power tailgate is an intelligent feature that automatically opens and closes the tailgate of a vehicle via an electric drive system, commonly found in SUVs, MPVs, and luxury sedans. Some owners of vehicles without this feature install a power tailgate themselves to achieve the same effect. However, existing DIY power tailgates often use a motor and structure that rotate together, with the PCBA board typically mounted below the motor. This causes the wiring to shift during the opening and closing of the tailgate, which is unsightly and significantly impacts wiring routing and wire selection. Therefore, a power tailgate drive gearbox housing with an integrated PCBA board is designed to solve these problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an electric tailgate drive gearbox housing with an integrated PCBA board, comprising: a back plate 1 with mounting holes at four corners; a drive chamber housing 2 fixedly connected to the front surface of the back plate 1; a drive chamber housing 3 connected to the front end of the drive chamber housing 2 by bolts; a steering gearbox housing 4 fixedly connected to the right side of the drive chamber housing 3; the front side of the steering gearbox housing 4 fixedly connected to the right side of the drive chamber housing 2; and a steering gearbox housing 5 connected to the right side of the steering gearbox housing 4 by bolts. The front end of housing 2 3 is fixedly connected to a reduction gearbox housing 6. The front end of the reduction gearbox housing 6 and the steering gearbox housing 2 5 are connected by bolts to a reduction gearbox cover 7. The left side of the drive cavity housing 1 2, drive cavity housing 2 3, reduction gearbox housing 6 and reduction gearbox cover 7 are connected by bolts to an end cover 8. A PCBA board mounting groove is opened inside the left end of the end cover 8. A PCBA board 9 is fixedly connected inside the PCBA board mounting groove. A circuit interface 10 is fixedly connected to the upper end of the end cover 8. The circuit interface 10 is electrically connected to the PCBA board 9.

[0025] In use, the motor is snapped into the left side of the drive chamber housing 2. After closing the drive chamber housing 3, the motor output end is extended to the position of the steering gearbox housing 4 and snapped into the steering drive gear. Then, the other two transmission gears are snapped into the inside of the steering gearbox housing 4. After that, a series of reduction gears are snapped into the reduction gearbox housing 6. The transmission component is then connected to the leftmost side. The steering gearbox housing 5 and the reduction gearbox cover 7 are closed. The PCBA board 9 is electrically connected to the motor wires. Then, the upper cover 8 is connected by bolts. After installation, the back plate 1 is installed into the inside of the vehicle body by bolts. The control circuit and the circuit interface 10 are connected to complete the installation. When the motor rotates, it will drive the output gear to rotate. After steering, it will drive the reduction gear to rotate. Finally, the lifting mechanism will rotate. The position of the electric tailgate drive gearbox housing of the integrated PCBA board remains unchanged, and the wires connected to the upper circuit interface do not change.

[0027] Analysis of the above structure shows that bearings are fitted onto the outer sides of the buffer and the Hall sensor, and then snapped into the buffer and Hall sensor mounting slot 21. The motor, buffer and Hall sensor are connected by gears. When the motor suddenly rotates, the buffer can activate the buffering function to reduce the wear on the gears, while the Hall sensor records the number of rotations. The Hall sensor is then electrically connected to the control terminal to achieve the control function.
