[0023] Please see Figures 1-6As shown, this utility model provides a technical solution:

[0024] A flexible, openable armrest hinge with a hovering function includes a movable support 1, a fixed support 2, and two sets of connecting components 3 located between the fixed support 2 and the movable support 1. The two sides of the fixed support 2 are rotatably connected to the two sides of the movable support 1 via a set of connecting components 3. The connecting components 3 are symmetrically distributed along the center lines of the movable support 1 and the fixed support 2. Each connecting component 3 includes a pivot, a first damping plate 34, a driving plate 35, and a second damping plate 36. A first stop post 37 is fixedly installed at the inner end of the pivot 31, and the other end of the pivot 31 passes sequentially through the movable support 1 and the fixed support 2. Between the movable support 1 and the fixed support 2, from the inside out, are arranged a second damping plate 36, a driving plate 35, and a first damping plate 34. A second stop post 32 is sleeved on the outermost side of the pivot 31, and a third damping plate 33 is provided between the second stop post 32 and the movable support 1. This armrest hinge controls the movable seat 2 to hover at any time during rotation around the pivot 31 by adjusting the damping of the damping plates.

[0025] In this embodiment, the movable bracket 1 has a plurality of first fixing holes 11 evenly provided in the middle for fixing the movable bracket 1 to the cover plate of the armrest box. The movable bracket 1 extends outward in a "J" shape on both sides, and a square drive groove 12 is provided at its tail end.

[0026] In this embodiment, the driving plate 35 has two driving teeth 351 at the top, a first spring clip interface 352 at the bottom, and a spring height limiting plate 353 extending from the middle towards the fixed bracket 2. The first damping plate 34 has a square driving post 341 on its outer side. The driving post 341 extends a distance to both sides along the axial direction of the first damping plate 34. One end of the driving post 341 is engaged in the driving groove 12 of the movable bracket 1, and the other end is movably disposed between the two driving teeth 351 at the top of the driving plate 35. The size of the driving post 341 is the same as the size of the driving groove 12.

[0027] In this embodiment, the fixing bracket 2 is generally in a "C" shape as a whole. The fixing bracket 2 extends obliquely upward along both sides to form tails with a certain dimension. A plurality of second fixing holes 21 are evenly formed in the middle of the fixing bracket 2. Second spring snap-in interfaces 22 are symmetrically formed on the upper edge of the fixing bracket 2. An elastic component 4 is provided on the side of the fixing bracket 2. The elastic component 4 includes a fixing shaft 41, a left driving spring 42 and a right driving spring 43. The fixing shaft 41 is inserted into the side of the fixing bracket 2. The left driving spring 42 and the right driving spring 43 are symmetrically sleeved on the fixing shaft 41. Both ends of the left driving spring 42 and the right driving spring 43 extend outward a certain distance along the vertical direction of the driving spring and are respectively snapped into the first spring snap-in interface 352 and the second spring snap-in interface 22. A first limiting plate 23 is provided on the upper side of the tail of the fixing bracket 2 to cooperate with the elastic height limiting plate 353 to limit the elastic height of the driving piece 35. A second limiting plate 24 is provided on the lower side to limit the position of the driving piece 35 when the hinge is closed. A buffer sleeve 231 is sleeved outside the first limiting plate 23. The material of the buffer sleeve 231 is preferably latex.

[0028] The use process of the armrest hinge with an elastic opening and hovering function in this embodiment is as follows: When the armrest is closed, the driving spring is compressed and undergoes elastic deformation, and the spring snap-in interface receives the elastic force exerted by the driving spring. When opening the armrest box, under the action of the elastic force, the driving piece 35 rotates. The driving teeth 351 on the driving piece 35 drive the driving column 341 to rotate. The driving column 341 drives the first damping piece 34 and the movable bracket 1 to move upward around the rotating shaft 31. After the driving piece 35 rotates a certain angle, it will be blocked by the first limiting plate 23, which blocks the rotation of the driving piece 35 and limits the elastic height of the movable bracket 1. Before the driving piece 35 contacts the first limiting plate 23, the driving spring has already restored to its original shape, the elastic force disappears, and the connecting component 3 is no longer subject to the elastic force. The movable bracket 1 is controlled to hover at any time only by the frictional force generated between the movable bracket 1, the fixing bracket 2 and the connecting component 3.

[0029] 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 by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
