[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-3 The utility model provides an embodiment: a hinge for an automobile armrest, comprising a chain plate 1 and a chain plate 2, wherein a fixed shaft 3 is fixedly connected inside the chain plate 1, a side plate 4 is fixedly connected to the side wall of the chain plate 22, a fixed shaft 2 5 is fixedly connected between the side plates 4, a swivel 1 6 is rotatably connected to the side wall of the fixed shaft 25, a round tube 7 is fixedly connected to the side wall of the swivel 16, a limiting column 8 is fixedly connected inside the round tube 7, a slide cylinder 9 is slidably connected to the side wall of the limiting column 8, a spring 10 is sleeved on the side wall of the limiting column 8, one end of the spring 10 is fixedly connected to the inside of the round tube 7, the other end of the spring 10 is fixedly connected to the side wall of the slide cylinder 9, a swivel 2 11 is fixedly connected to the side wall of the slide cylinder 9, the inner side wall of the swivel 2 11 is rotatably connected to the side wall of the fixed shaft 3, and a connecting component is provided at the bottom of the chain plate 1.

[0023] First, we fix the chain plate 2 to the inside of the hand box to ensure its firmness. Then, fix the chain plate 1 to the box cover so that it can move with the opening and closing of the box cover. When the box cover is opened, the chain plate 1 will move with it and drive the swivel 2 11 to rotate on the fixed shaft 3. It interacts with the fixed shaft 3 to keep the box cover stable during the opening process. At the same time, the swivel 16 also rotates on the fixed shaft 2 5, and this action pulls the slide 9 outward. The slide 9 slides outward inside the round tube 7 and stretches the spring 10. The spring 10 is deformed after being stretched, thereby enhancing the stability of the box cover. When the box cover is closed, the spring 10 will reset due to the loss of tension. At this time, the slide 9 is moved into the inside of the round tube 7 again. This process makes the box cover more stable when closed, avoiding possible shaking or loosening.

[0024] Reference Figure 4 The connecting assembly includes a connecting plate 12, the side wall of the connecting plate 12 is fixedly connected to the side wall of the chain plate 1, the side wall of the chain plate 2 is fixedly connected to the side frame 13, a sliding rod 14 is arranged between the connecting plate 12 and the side frame 13, the side wall of the sliding rod 14 is slidably connected inside the connecting plate 12 and the side frame 13, a thread groove 15 is opened in the middle of the side wall of the sliding rod 14, a fastening bolt 16 is arranged on the side wall of the sliding rod 14, the fastening bolt 16 is threadedly connected to the side wall of the sliding rod 14 through the thread groove 15, a gasket 17 is slidably connected to the side wall of the sliding rod 14, a thread groove 2 18 is opened inside the sliding rod 14, a fastening bolt 2 19 is arranged inside the sliding rod 14, and the fastening bolt 2 19 is threadedly connected to the inside of the sliding rod 14 through the thread groove 2 18.

[0025] When assembling the chain plate 1 and the chain plate 2, first, one end of the slide bar 14 is passed through one side of the side frame 13 and the connecting plate 12, and then the gasket 17 is slid on the slide bar 14. The gasket 17 plays a buffering role here, which can effectively reduce the vibration and impact generated by the equipment during use, thereby improving the stability and service life of the equipment. Then, the fastening bolt 16 is installed on the slide bar 14. This step is to further fix the position of the slide bar 14 between the side frame 13 and the connecting plate 12 to ensure that the assembled equipment can withstand sufficient pressure and vibration. Next, the slide bar 14 is passed through the other side of the connecting plate 12 and the side frame 13. By twisting the fastening bolt 16, it drives the gasket 17 to move until it is attached to the side wall of the connecting plate 12. Finally, the fastening bolt 2 19 is twisted inside the slide bar 14, and the connecting plate 12 and the side frame 13 are restricted on the slide bar 14 by the fastening bolt 2 19 and the fastening bolt 16. The assembly quality of the chain plate 1 and the chain plate 2 is ensured, making the equipment more stable and reliable during use. At the same time, various problems and failures caused by equipment deformation are avoided, and the service life of the equipment is increased.

[0026] Working principle: fix the chain plate 2 inside the hand box, and then fix the chain plate 1 on the box cover. When the box cover is opened, the chain plate 1 will move with it, and make the swivel 2 11 rotate on the fixed shaft 3, and make the swivel 16 rotate on the fixed shaft 2 5, and at the same time pull the slide 9 outward, so that it slides outward inside the round tube 7 and stretches the spring 10 to deform it. When closing the box cover, the spring 10 will reset due to the loss of tension, and move the slide 9 into the inside of the round tube 7 again, so as to achieve the effect of making the box cover more stable when opening and closing. When assembling the chain plate 1 and the chain plate 2, first pass one end of the slide rod 14 through the side frame 13 and one side of the connecting plate 12, this is to slide the gasket 17 on the slide bar 14, install the fastening bolt 16 on the slide bar 14, and then pass the slide bar 14 through the other side of the connecting plate 12 and the side frame 13, then twist the fastening bolt 16 to drive the gasket 17 to move until it fits on the side wall of the connecting plate 12, and finally twist the fastening bolt 2 19 inside the slide bar 14, and restrict the connecting plate 12 and the side frame 13 on the slide bar 14 by the fastening bolt 2 19 and the fastening bolt 16, so as to ensure the effect of consistent pressure during rotation and avoid the situation that the pressure on one side of the equipment is too large and the equipment is deformed and cannot be used.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
