[0002] Currently, vehicles are equipped with actuator assemblies that power components such as the vehicle's thermal management system, windows, wipers, and power seats.
[0003] In the related art, since components such as the vehicle's thermal management system, windows, wipers and electric seats require a certain level of control accuracy, the control accuracy of the actuator assembly needs to be improved. However, in order to improve the control accuracy of the actuator assembly, the structure of the actuator assembly is relatively complex. Summary of the invention
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.
[0005] To this end, a first aspect of the present invention provides an actuator assembly.
[0006] A second aspect of the present invention provides a vehicle.
[0007] In view of this, a first aspect of the present invention provides an actuator assembly, including a shell, a circuit board, a detection component, a motor, a transmission rod and a magnetic component; the circuit board is connected to the shell and is arranged opposite to the bottom wall of the shell; the detection component is arranged on the circuit board and is located on the side of the circuit board facing the bottom wall of the shell; the motor is arranged in the shell, and the output shaft of the motor is parallel to the bottom wall of the shell; the transmission rod is connected to the output shaft of the motor; the magnetic component is arranged on the transmission rod and is opposite to the detection component, and the detection component is used to detect the change of the magnetic pole of the magnetic component.
[0008] The actuator assembly provided in the present application includes a housing and a motor. The motor is arranged in the housing. The motor can output power, thereby enabling the actuator assembly to output power to control the movement of matching components. The actuator assembly also includes a circuit board, a detection component and a magnetic component. The circuit board is arranged in the housing, and the circuit board is supported by the housing. The detection component is arranged on the circuit board, the transmission rod is connected to the output shaft of the motor, the magnetic component is arranged on the transmission rod, and the magnetic component is opposite to the detection component. When the motor outputs power, the motor can drive the magnetic component to move, and the detection component can detect the change of the magnetic pole of the magnetic component, thereby realizing the detection of the angle or position of the power output end of the actuator assembly. Since the angle or position of the power output end of the actuator assembly can be detected by the detection component, the circuit board can control the angle or position of the power output end of the actuator assembly, thereby improving the control accuracy of the actuator assembly; and the angle or position of the power output end of the actuator assembly can be controlled by the detection component in cooperation with the magnetic part, so that there are fewer components related to the control of the actuator assembly, and the structure of the actuator assembly is relatively simple. While improving the control accuracy of the actuator assembly, the structure of the actuator assembly is simplified, the volume of the actuator assembly is reduced, and the space occupied by the actuator assembly is reduced, which is conducive to the miniaturization of the actuator assembly; the structure of the actuator assembly is simplified, and the weight of the actuator assembly can also be reduced, thereby facilitating the lightweighting of the actuator assembly. In addition, since the structure of the actuator assembly is simplified, the production and manufacturing process of the actuator assembly can also be simplified, thereby reducing the manufacturing cost of the actuator assembly and improving the production efficiency of the actuator assembly.
[0009] The angle or position of the power output end of the actuator assembly is controlled by cooperating with the detection component and the magnetic component. While simplifying the structure of the actuator assembly, the stability of the angle or position of the power output end of the actuator assembly can be improved, thereby improving the stability of the actuator assembly during operation, making the working process of the actuator assembly more reliable.
[0010] Furthermore, the detection component may be a magnetic sensor, the magnetic component may be a magnet, the motor may be a motor, and the output end of the motor may be the output shaft of the motor. When the motor is working, the output shaft of the motor can drive the magnet to rotate. The rotation of the magnet driven by the output shaft of the motor will cause the magnetic field generated by the magnet to change accordingly. The magnetic sensor can detect the change in the magnetic field generated by the magnet, and then determine the angle or position of the output shaft of the motor according to the change in the magnetic field generated by the magnet, thereby realizing the control of the angle or position of the output end of the actuator assembly.
