According to the actuator 100 for adjusting the vehicle-mounted display terminal 1 of the embodiment of the invention, as shown in fig. 1-2, the axis of the gear 62 is coincident with the axis of the output shaft of the rotating mechanism 7, so that the gear 62 and the rotating mechanism 7 can be coaxially mounted, the mounting process is reduced, the mounting of the gear 62 and the rotating mechanism 7 is facilitated, the rotation center of the first sliding part 31 is positioned on the axis of the gear 62, the rotation center of the second sliding part 32 is positioned on the axis of the output shaft of the rotating mechanism 7, the gear 62 is meshed with the rack 63, the geometric center of the rack 63 changes along with the change of the meshing point, the driving force output by the rotating mechanism 7 is facilitated to drive the first sliding part 31, the second sliding part 32 and the display terminal 1 to rotate, the power consumption in the transmission process of the rotating mechanism 7 is reduced, the transmission efficiency between the rotating mechanism 7 and the second sliding part 32 is improved, and the center-changed rotation of the display terminal is realized, the gear 62 is coaxially arranged with the output shaft of the rotating mechanism 7, which is beneficial to the overall structural arrangement of the actuator 100, so that each part of the actuator 100 is compactly installed, and the space occupied by the actuator 100 is reduced.

The first engagement portion 73 and the second engagement portion 74 form a circumferential static friction force under the axial biasing force, and the circumferential static friction force forms an opening force for relative rotation of the first engagement portion 73 and the second engagement portion 74. When the torque applied to the first engaging portion 73 is larger than the opening force, the first engaging portion 73 and the second engaging portion 74 rotate relatively to change the engaging position; when the first engagement portion 73 receives a torque smaller than the opening force, the first engagement portion 73 and the second engagement portion 74 are kept engaged with each other to transmit the torque.

Specifically, during operation of the actuator 100, when the driving unit 75 is not operated and the first engaging portion 73 receives a torque greater than the opening force, the second engaging portion 74 rotates relative to the first engaging portion 73 to change the engaging position.

For example, a torque for rotating the display terminal 1 is manually applied to the display terminal 1, the torque is transmitted to the first engaging portion 73 through the rotating disk, the driving unit 75 is fixedly connected with the second engaging portion 74 because the driving unit 75 is locked when not operating, and when the torque is not greater than the opening force, the first engaging portion 73 is engaged with the second engaging portion 74, and the display terminal 1 does not rotate; when the torque is larger than the opening force, the first engaging portion 73 and the second engaging portion 74 rotate relatively to each other from the previous engaging position to the other engaging position, and when the first engaging portion 73 rotates from the first engaging position to the second engaging position with respect to the second engaging portion 74, the manual rotation of the display terminal 1 can be realized.
