[0026] See also Figure 1-Figure 7 As shown, the utility model provides a technical solution:

[0027] A two-stage armrest hinge includes a fixed seat 1, a movable seat 2 and a connecting component 3. Among them, the fixed seat 1 is fixedly installed inside the box body of the armrest box, and the movable seat 2 is fixedly installed on the armrest cover plate. First shaft holes 11 are symmetrically formed on both sides of the fixed seat 1, and second shaft holes 21 are symmetrically formed on both sides of the movable seat 2. The two sides of the fixed seat 1 and the two sides of the movable seat 2 are respectively rotationally connected through the connecting component 3. The connecting component 3 includes a rotating shaft 31, a shaft sleeve 32, a torsion spring 33, a damping piece 34, a damping baffle 35, and a fixed clamping spring 36. A stop post 37 is fixedly arranged at one end of the rotating shaft 31. The other end of the rotating shaft 31 sequentially passes through the shaft sleeve 32, the first shaft hole 11, the torsion spring 33, the second shaft hole 21, the damping piece 34, the damping baffle 35, and the fixed clamping spring 36. The connecting component 3 is fixed by the interference fit of the fixed clamping spring 36 and the rotating shaft 31. The torsion spring 33 is sleeved outside the rotating shaft 31. One end of the torsion spring 33 is clamped with the fixed seat 1, and the other end of the torsion spring 33 is clamped with the movable seat 2. The maximum opening and closing angle between the movable seat 2 and the fixed seat 1 is controlled by the torsion spring 33. By adjusting the damping of the damping piece 34, the movable seat 2 can be suspended at any time during the rotation process.

[0028] In this embodiment, the fixed seat 1 is in a "C" shape. A plurality of first fixing holes 14 are evenly formed in the middle of the fixed seat 1. The two ends of the fixed seat 1 are symmetrically provided with the first shaft holes 11. The plurality of first fixing holes 14 are used to fixedly install the fixed seat 1 inside the box body of the armrest box.

[0029] In addition, baffles 12 and limit plates 13 are symmetrically arranged at both ends of the fixed seat 1 respectively. The baffle 12 is located at a position slightly below the first shaft hole 11, and the baffle 12 is clamped with one end of the torsion spring 33. The limit plate 13 is located above the first shaft hole 11. The length of the limit plate 13 is greater than the distance between the first shaft hole 11 and the second shaft hole 21. A buffer sleeve 131 is sleeved outside the limit plate 13. The material of the buffer sleeve 131 is preferably latex. The limit plate 13 is used to limit the movement of the movable plate 12 during rotation to prevent the movable seat 2 from colliding with the fixed seat 1 during the rotation process.

[0030] In this embodiment, the movable seat 2 includes a movable plate 22 and hinge parts 23 symmetrically extending at one end of the movable plate 22. The hinge parts 23 are in a "J" shape. A second shaft hole 21 is formed at the end of the hinge part 23 far from the movable plate 22. The end of the hinge part 23 far from the movable plate 22 is clamped with one end of the torsion spring 33. A plurality of second fixing holes 221 are evenly formed on the movable plate 22. The plurality of second fixing holes 221 are used to fixedly install the movable seat 2 on the armrest cover plate.

[0031] When assembling the two-stage armrest hinge of this embodiment, first, the fixed seat 1 is fixedly installed on the inside of the armrest box through multiple first fixing holes 14, and the movable seat 2 is fixedly installed on the armrest cover through multiple second fixing holes 221. Then, the end of the rotating shaft 31 in the connecting component 3 away from the block column 37 passes through the shaft sleeve 32, the first shaft hole 11, the torsion spring 33, the second shaft hole 21, the damping plate 34, the damping baffle 35, and the fixed retaining spring 36 in sequence, and the connecting component 3 is fixed by the fixed retaining spring 36. The torsion spring 33 is sleeved on the outside of the rotating shaft 31, and one end of the torsion spring 33 is clamped with the baffle 12 at one end of the fixed seat 1, and the other end of the torsion spring 33 is clamped with the end of the hinged portion 23 of the movable seat 2 away from the movable plate 22, thereby completing the assembly of the two-stage armrest hinge.

[0032] The usage process of the two-stage armrest hinge of this embodiment is as follows: when the armrest box needs to be opened or closed, the armrest cover is directly opened. Under the action of the torsion spring 33, the movable seat 2 bounces up to a certain height. During the process of the movable seat 2 rotating around the connecting component, friction is generated between the movable seat 2 and the damping plate 34, so that the movable seat 2 and the armrest cover can hover at any time.

[0033] In this embodiment, the two-stage armrest hinge controls the maximum opening and closing angle of the movable seat 2 and the fixed seat 1 through the torsion spring 33, thereby controlling the height of the movable seat 2 when it rotates and bounces up; by adjusting the damping of the damping plate 34 between the fixed seat 1 and the movable seat 2, the movable seat 2 is controlled to hover at any time during the rotation process.

[0034] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
