Specifically, referring to fig. 2 to 4, the first damping assembly 2 is provided with a first transmission shaft 21, a first damping elastic member 22, and a first damping moving block 23. The first damping elastic member 22 and the first damping moving block 23 are both disposed in the first housing 24 having an extending axial direction, the first damping elastic member 22 can output elastic potential energy acting outwards along the extending axial direction of the first housing 24 when being deformed, and the first damping moving block 23 can slide in the first housing 24 along the extending axial direction thereof. Alternatively, the inner end of the first transmission shaft 21 may be provided with a shaft core extending in the first housing 24, the first damping moving block 23 is sleeved on the shaft core and can slide along the shaft core in an oriented manner, and the first housing 24 may be provided with a mounting ear for fixedly assembling the first housing 24 with the fixing surface.

The first damping elastic member 22 is axially connected to the first end of the first damping moving block 23 along the length of the first housing 24, for example, may be fixedly connected to the first end of the first damping moving block 23 or abut against the first end of the first damping moving block 23, and when the first damping elastic member 22 deforms in the first housing 24 to perform elastic potential energy action, the first damping elastic member can act to drive the first damping moving block 23 to directionally slide in the first housing 24.

The first end of the first transmission shaft 21 and the first housing 24 are coaxially assembled in the first housing 24 in a limiting manner, and the second end extends out of the first housing 24, so that the first transmission shaft 21 can rotate relative to the first housing 24.

Also, the second end of the first damping moving block 23 is inclined-fitted with the first end of the first transmission shaft 21. Specifically, the first end of the first transmission shaft 21 has a first inclined surface 211, and the second end of the first damping moving block 23 has a second inclined surface 231, where the first inclined surface 211 and the second inclined surface 231 are mutually corresponding inclined surfaces in the axial direction, even curved surfaces that are mutually engaged, and the second end of the first transmission shaft 21 is defined as an output end. When the first damping moving block 23 slides in the axial direction, the axial sliding is converted into a rotational driving of the first transmission shaft 21 by the cooperation of the second inclined surface 231 and the first inclined surface 211, so that the first transmission shaft 21 is caused to rotate relative to the first housing 24.

When the turnover driving piece 1 drives the compression springs to compress and deform, the elastic potential energy of the compressed compression springs acts on the first damping moving blocks 23, so that the first damping moving blocks 23 move close to the first transmission shaft 21, and the first damping moving blocks 23 are matched with the inclined planes of the first inclined planes 211 through the second inclined planes 231 in the process of moving close to the first transmission shaft 21, so that the first transmission shaft 21 is driven to rotate, and damping transmission output is realized.

When the damping action is performed, the second compression spring 222 can generate fine and rapid damping change, the first compression spring 221 can generate slow and rough damping change, and the damping changes of the second compression spring and the first compression spring are in synergistic action, so that the damping output of the first transmission shaft 1 is free from obvious pause, and sensitive and stable damping output can be realized.

Furthermore, the tumble drive 1 may be, but is not limited to, a motor, a cylinder or a hydraulic cylinder. Furthermore, the output of the tilting drive 1 can be connected to the first damping spring 22 in a transmission manner, either by direct action or by using other intermediate transmission mechanisms.

In a further preferred embodiment, a first position sensor 4 is arranged in connection with the first drive shaft 21, which first position sensor 4 is arranged in particular at the output of the first drive shaft 21, and can detect the rotational travel or position of the first drive shaft 21. The first position sensor 4 is in communication connection with the overturning driving piece 1 through the controller 8, and can feed back detected travel or position information to the controller 8, the overturning driving piece 1 is instructed to act by the controller 8 according to the feedback information, and the overturning driving piece 1 performs elastic deformation driving of the first damping elastic piece 22, so that automatic adjustment control of damping transmission output is realized.

When the turnover driving piece 1 drives the first push rod 3 to move along the direction close to the pressure spring, the pressure spring is compressed, the compressed pressure spring drives the first damping moving block 23 to move, and then the damping drives the first transmission shaft 21 to rotate so as to realize damping transmission output. When the turnover driving piece 1 resets, the first push rod 3 can be driven to reset, or the first push rod 3 can be driven to reset by the reverse action of the first damping moving block 23 and the first damping elastic piece 22 in the resetting process of the first transmission shaft 21.
