Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0018] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the armrest damping connection rotation structure of the present invention in conjunction with the accompanying drawings.

[0019] See also Figures 1-4, an armrest damping connection rotation structure, including an armrest base 1, the upper end of the armrest base 1 is symmetrically connected to the left and right sides with an armrest cover 2, the lower end of the armrest cover 2 is provided with an inner cavity 5, the surface of the inner cavity 5 is clamped and covered with a cover plate 4, the left and right rear ends of the upper end of the armrest base 1 are fixed with an axle seat 3, the axle seat 3 is located inside the inner cavity 5, the front of the axle seat 3 is installed with a rotating shaft 7, the front side movable sleeve of the rotating shaft 7 is provided with a damping sleeve 9, the front end of the axle seat 3 is fixedly connected There is a shaft sleeve 8, the rear part of the rotating shaft 7 extends into the interior of the shaft sleeve 8 and is fixedly connected to the shaft sleeve 8, a fixing plate 6 is fixed to the inner wall of the inner cavity 5, the damping sleeve 9 is fixed to the rear end of the fixing plate 6, and the front part of the rotating shaft 7 is movably penetrated with the fixing plate 6. When the armrest cover 2 is rotated, the armrest cover 2 rotates with the rotating shaft 7 as the center of the circle. During this process, the rotating shaft 7 will be rotatably connected with the fixing plate 6, but the rotating shaft 7 itself will not rotate. In this way, the damping sleeve 9 movably sleeved on the outside of the rotating shaft 7 makes relative motion;

[0020] The damping sleeve 9 is internally and evenly fixedly connected with six to eight shafts 12 in an annular shape. The shafts 12 are externally rotatably connected with a damping member. One end of the damping member is in close contact with the outer wall of the rotating shaft 7. A second torsion spring 15 is installed on the outside of the shaft 12 and on one side of the damping member. The first and second ends of the second torsion spring 15 are respectively fixed to the outer wall of the shaft 12 and the side of the damping member. The damping member is composed of a rotating plate 13 and a damping pad 14. The rotating plate 13 is rotatably connected to the outside of the shaft 12, and the damping pad 14 is fixedly connected to the end of the rotating plate 13. The damping pad 14 is The outer wall of the rotating shaft 7 is in close contact with the damping pad 14, and the end surface of the damping pad 14 close to the rotating shaft 7 is an arc surface, which matches the arc surface of the outer wall of the rotating shaft 7. By arranging the damping sleeve 9 on the outside of the rotating shaft 7, and providing six to eight rotating plates 13 on the inner wall of the damping sleeve 9, the damping pad 14 of the rotating plate 13 is in close contact with the outer part of the rotating shaft 7, and the second torsion spring 15 is provided to give the damping pad 14 an elastic force, so that the damping pad 14 is always in close contact with the outer part of the rotating shaft 7.

A limiting seat 10 is fixed to the outside of the rotating shaft 7, and a limiting opening is opened on the surface of the limiting seat 10. The head end of the first torsion spring 11 extends into the inside of the limiting opening. When the armrest cover 2 rotates from a vertical state to a horizontal state, it rotates around the rotating shaft 7 as the center, but the rotating shaft 7 does not rotate by itself, so the first torsion spring 11 will be compressed. The setting of the first torsion spring 11 is used to make the armrest cover 2 automatically rotate from a horizontal state to a vertical state after being unlocked, and by arranging the limiting seat 10 on the outside of the rotating shaft 7, the first torsion spring 11 can be prevented from falling off.
