This application discloses an actuator, a cover assembly, and a vehicle. The drive mechanism includes a motor and a torque application assembly. The motor includes a motor shaft. The torque application assembly is configured to apply a first torque to the motor shaft when it rotates in a first rotational direction, and not to apply a torque to the motor shaft when it rotates in a second rotational direction; or, it is configured to apply a first torque to the motor shaft when it rotates in the first rotational direction, and apply a second torque to the motor shaft when it rotates in the second rotational direction. The first rotational direction is opposite to the second rotational direction. The first torque is greater than the second torque. Thus, when the motor is not energized, the motor shaft, which is conducive to rotation in the first rotational direction, is self-locked under the action of the first torque, while the motor shaft, which is conducive to rotation in the second rotational direction, is not resisted or continues to rotate under the action of a smaller second torque.

This utility model relates to the field of expansion joint technology, providing a force-transmitting expansion joint, including a sleeve, with an inner tube disposed on one side inside the sleeve. Self-locking fixing structures are fixed to the outer walls of both the sleeve and the inner tube. Each self-locking fixing structure includes adjusting blocks uniformly fixed to the outer wall of the inner tube, and positioning blocks uniformly fixed to the outer wall of the sleeve. By providing self-locking fixing structures, this utility model facilitates precise connection between the sleeve and the inner tube under the connection and guidance of the screw. The dual locking action of the first and second self-locking bolts increases the stability of the connection between the sleeve and the inner tube. The limiting action of the limiting bolts facilitates control of the expansion distance between the sleeve and the inner tube. This device achieves the functions of easy self-locking, easy fixing, and easy adjustment of the distance between the sleeve and the inner tube, improving the working efficiency and convenience of the force-transmitting expansion joint during use.

The utility model relates to rubber fender suspension technical field, and disclose a kind of for connecting rubber fender's hanger, including backplate, the top of backplate left side is fixedly connected with adjusting box, and the top and bottom of adjusting box inner cavity are rotatably connected with screw rod between through bearing, the outer surface of screw rod is connected with rectangular plate with screw thread, the left side of rectangular plate is fixedly connected with driving plate, the left side of backplate and located the outside of adjusting box are slidably connected with concave suspension frame, the utility model is connected with rectangular plate, driving plate, concave suspension frame, mounting hole and rocking handle by setting backplate, adjusting box, screw rod, can be suspended installation to rubber fender, simultaneously, it is convenient to carry out vertical adjustment to its installation position, by setting limiting component, rocking handle can be conveniently self-locked, avoid self-rotation movement, influence installation height, by setting above structure, can have installation adjustment function, to satisfy the use demand of customer, avoid that there is limitation in installation use.
