[0003] However, the existing tailgate support rods are large in size, making them inconvenient to install on car tailgates, and the connection structure between the controller and the motor is complex, making assembly difficult. Utility Model Content

This design solves the problem of the large size of the existing tailgate support rod, reduces the overall structural size, and makes it easier to install on the tailgate of the car. At the same time, it simplifies the connection between the drive motor and the controller and reduces the complexity of the assembly process.

[0008] Preferably, the PCB board is provided with a sensor for detecting the number of rotations of the motor output shaft to calculate the strut stroke, and the drive motor output shaft extends into the housing and is located close to the PCB board.

[0009] By adopting the above technical solution, the sensor can detect the number of rotations of the motor output shaft, and then calculate the stroke of the strut based on the number of rotations of the motor output shaft, and feed the information back to the controller; the controller can accurately control the operation of the drive motor based on the feedback data, thereby realizing the precise opening and closing of the car tailgate and preventing component damage or operational errors caused by excessive extension and retraction.

[0010] Preferably, the end of the drive motor output shaft near the PCB board is fitted with a detection ring for auxiliary sensor detection.

[0011] By adopting the above technical solution, the sensor can detect the number of rotations of the motor output shaft by detecting the number of rotations of the detection ring, making the data detection more accurate, ensuring the accuracy of the strut movement, realizing the precise opening and closing of the car tailgate, and preventing component damage or operational errors caused by excessive extension and retraction.

[0012] Preferably, a waterproof connector is installed at the end of the housing away from the drive motor, and a sealing ring is provided at the connection between the waterproof connector and the housing. The PCB board is located at the end of the housing near the waterproof connector. The waterproof connector has a mounting hole for introducing a wire harness to electrically connect with the PCB board.

[0013] By adopting the above technical solution, the waterproof connector initially seals the inside of the housing, and the sealing ring can effectively prevent external moisture, dust and other impurities from entering the housing, providing waterproof and dustproof protection for precision components such as PCB boards and drive motors, and extending the service life of the structure; the mounting holes of the waterproof connector provide a standardized interface for the connection between the wire harness and the PCB board, which facilitates the standardized installation of the wire harness and further simplifies the assembly process.

[0017] By adopting the above technical solution, the PCB board fits the cross-sectional contour of the housing, which can maximize the use of the space inside the housing, avoid space waste, and further optimize the compactness of the structure. The installation method perpendicular to the housing axis and the position close to the waterproof connector facilitate the connection between the PCB board and the wire harness introduced through the waterproof connector, reduce the length and complexity of the wire harness arrangement, and at the same time avoid spatial interference between the PCB board and the drive motor.

[0018] Preferably, the heat sink is a thermally conductive silicone pad, which is installed on the inner wall of the housing. One side of the heat sink is in contact with the mounting plate, and the other side of the heat sink is in contact with the PCB board.

[0019] By adopting the above technical solution, the thermally conductive silicone pad has excellent thermal conductivity and good flexibility, which can closely fit the surface of the PCB board and the housing, eliminating the gap between them. This allows the heat generated by the PCB board to be efficiently transferred to the housing and dissipated, improving heat dissipation efficiency. At the same time, the heat dissipation component provides support for the PCB board, making the PCB board installation more stable.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

This design solves the problem of the large size of existing tailgate support rods, reduces the overall structural size, and facilitates installation on the tailgate of a car. At the same time, it simplifies the connection between the drive motor and the controller and reduces the complexity of the assembly process.

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail.

[0028] This application discloses a tailgate strut structure with an integrated controller.

[0029] refer to Figure 1 and Figure 2 A tailgate strut structure with integrated controller 3 includes a housing 1, a drive motor 2, a controller 3, and a waterproof connector 4. The housing 1 is a cylindrical housing 1 cast from magnesium-aluminum alloy. The controller 3 is installed at one end of the housing 1. The drive motor 2 is bolted to the end of the housing 1 away from the controller 3 and its output shaft is coaxial with the housing 1. The waterproof connector 4 is snap-fitted and fixedly installed at the end of the housing 1 away from the drive motor 2. The controller 3 is located on the housing 1 near the waterproof connector 4.

[0030] refer to Figure 2 The controller 3 includes a PCB board 31 on which multiple components 311 are mounted. The PCB board 31 is a circular plate that fits the cross-sectional outline of the housing 1. The PCB board 31 is set perpendicular to the axis of the housing 1. A mounting plate 5 is fixed to one end of the housing 1 near the waterproof connector 4. The mounting plate 5 is also a circular plate and is perpendicular to the axis of the housing 1. A connecting post 6 is provided on the mounting plate 5. The connecting post 6 passes through the edge of the PCB board 31 and fixes the PCB board 31 to the mounting plate 5.

[0031] The core component PCB board 31 of the controller 3 is integrated with the drive motor 2 inside the same housing 1, realizing an integrated structural design. This design solves the problem of the large size of the existing tailgate support rod, reduces the overall structural size, and makes it easier to install on the tailgate of a car. At the same time, it simplifies the connection between the drive motor 2 and the controller 3 and reduces the complexity of the assembly process.

[0032] The PCB board 31 fits the cross-sectional contour of the housing 1, which can maximize the use of the space inside the housing 1, avoid space waste, and further optimize the compactness of the structure. The installation method perpendicular to the axis of the housing 1 and the position close to the waterproof connector 4 make it easy for the PCB board 31 to be connected to the wire harness introduced through the waterproof connector 4, reducing the length and complexity of the wire harness arrangement, while avoiding spatial interference between the PCB board 31 and the drive motor 2.

[0033] refer to Figure 2 The output shaft of the drive motor 2 passes through the mounting plate 5 and is rotatably connected to the mounting plate 5 via a bearing. A detection ring 7 is fitted on one end of the drive motor 2 near the PCB board 31. A sensor 8 is fixed and electrically connected on the PCB board 31 to detect the number of rotations of the motor output shaft in order to calculate the strut stroke. In this embodiment, the sensor 8 is a Hall sensor 8.

[0034] Sensor 8 can detect the number of rotations of the detection ring 7 and thus the number of rotations of the motor output shaft. It calculates the stroke of the strut based on the number of rotations of the motor output shaft and feeds the information back to controller 3. Controller 3 can accurately control the operation of drive motor 2 based on the feedback data, thereby achieving precise opening and closing of the car tailgate and preventing damage to components or operational errors caused by excessive extension or retraction.

[0035] A heat sink 9 is provided between the housing 1 and the PCB board 31 to help dissipate heat from the PCB board 31. In this embodiment, the heat sink 9 is a thermally conductive silicone pad. The heat sink 9 is applied to the inner wall of the housing 1. One side of the heat sink 9 contacts the mounting plate 5, and the other side of the heat sink 9 contacts the PCB board 31 and provides support for the PCB board 31, making the installation of the PCB board 31 more stable. The thermally conductive silicone pad has excellent thermal conductivity and good flexibility, and can closely fit the surfaces of the PCB board 31 and the housing 1, eliminating the gap between them, thereby efficiently transferring the heat generated by the PCB board 31 to the housing 1 and dissipating it, improving the heat dissipation efficiency.

[0036] A sealing ring 10 is fitted at the connection between the waterproof connector 4 and the housing 1. The sealing ring 10 can effectively prevent external moisture, dust and other impurities from entering the interior of the housing 1, and play a role in waterproofing and dustproofing the precision components such as the PCB board 31 and the drive motor 2, thus extending the service life of the structure.

[0037] The waterproof connector 4 has a mounting hole 11 at the end away from the housing 1, through which external wire harnesses can be connected to the PCB board 31. This provides a standardized interface, facilitates the standardized installation of wire harnesses, and further simplifies the assembly process.

[0038] The implementation principle of this application embodiment is as follows: the drive motor 2 and the controller 3 are installed on the housing 1 one after the other, and then the waterproof connector 4 is installed. The core component PCB board 31 of the controller 3 and the drive motor 2 are integrated on the housing 1, realizing the integrated design of the structure, solving the problem of the large size of the existing tailgate support rod, reducing the overall structural size, so as to facilitate installation on the car tailgate; at the same time, it simplifies the connection method between the drive motor 2 and the controller 3 and reduces the complexity of the assembly process.
