[0045] Figure 1 The structural schematic diagram of the hinge provided for the embodiment of the present disclosure. As Figure 1As shown in the figure, the hinge includes a hinge body 1, a first folding assembly 2, and a second folding assembly 3. The first folding assembly 2 and the second folding assembly 3 are respectively rotatably connected to opposite sides of the hinge body 1. The first folding assembly 2 includes a first swing arm 21, a first transmission rod 22, and a first connecting member 23. One end of the first swing arm 21 is rotatably connected to the hinge body 1, and the other end of the first swing arm 21 is slidably connected to the first connecting member 23.

One end of the first transmission rod 22 is rotatably connected to one end of the second swing arm 31 close to the hinge body 1, and the other end of the first transmission rod 22 is rotatably connected to the first connecting member 23. One end of the second transmission rod 32 is rotatably connected to one end of the first swing arm 21 close to the hinge body 1, and the other end of the second transmission rod 32 is rotatably connected to the second connecting member 33. When the first swing arm 21 and the second swing arm 31 rotate relative to the hinge body 1, the first transmission rod 22 drives the first connecting member 23 to slide relative to the first swing arm 21, and the second transmission rod 32 drives the second connecting member 33 to slide relative to the second swing arm 31.

[0046] In the hinge provided in the embodiment of the present disclosure, opposite sides of the hinge body 1 are respectively rotatably connected to the first folding assembly 2 and the second folding assembly 3. The first swing arm 21 is slidably connected to the first connecting member 23, and the second swing arm 31 is slidably connected to the second connecting member 33.
