For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0026] A bracket hinge structure, such as Figure 1-Figure 6 As shown, it includes a base 1, an axle 2 and a base 2 3. The base 1 and the base 2 3 are connected by rotating the shaft 2. The base 1 includes an upper clamp 10 and a lower clamp 20 that are integrally bent and overlapped. The upper clamp 10 and the lower clamp 20 are symmetrical structures. There is an axial hole 12 between the upper clamp 10 and the lower clamp 20. The shaft 2 is set in the axial hole 12. A groove 201 is opened on the upper clamp 10 or the lower clamp 20. A fixing hook 101 is set on the lower clamp 10 or the upper clamp 20. The groove 201 is set corresponding to the fixing hook 101. The fixing hook 101 is bent and stuck in the groove 201, forming a fixing of the upper clamp 10 and the lower clamp 20. State and the clamping state of the rotating shaft 2, in this embodiment, the groove 201 is set at the opening on the upper clamping piece 10, and the fixed hook 101 is set at the opening on the lower clamping piece 20, and the groove 201 and the fixed hook 101 are arranged opposite to the shaft hole 12. In this way, in other embodiments, the groove 201 is arranged on the left and right sides or any side of the upper clamping piece 10, and the fixed hook 101 can be arranged on the corresponding left and right sides or any side of the lower clamping piece 20. A plurality of mounting holes 11 penetrating the upper clamping piece 10 and the lower clamping piece 20 are opened on the base 1, and the number of the mounting holes 11 is at least four, and the four mounting holes 11 are arranged in groups of two at both ends near the base 1.

[0027] As can be seen from the above, the utility model forms an axis hole 12 by the upper clamp 10 and the lower clamp 20, and utilizes the fixing hook 101 and the groove 201. The fixing hook 101 is bent and inserted into the groove 201, thereby forming a clamping and fixing state of the upper clamp 10 and the lower clamp 20, so that the upper clamp 10 and the lower clamp 20 tightly clamp the rotating shaft 2 in the axis hole 12, and are fixed to the assembled shell with screws or rivets in the mounting hole 11, effectively preventing the rotating shaft 2 from being worn and loosened due to long-term rotation, thereby affecting the user experience.

[0028] like Figure 1 , Figure 2 and Figure 4The two opposite sides of the base 2 3 are provided with shaft hole ears 31, and the two shaft hole ears 31 are provided with opposite shaft fixing holes. The shaft rod 2 passes through the shaft hole 12 and is fixedly connected to the shaft fixing holes on the shaft hole ears 31 on both sides of the base 2 3. The two opposite sides of the shaft rod 2 are provided with extrusion platforms 21, and the extrusion platform 21 is a plane formed on the shaft rod 2. The position corresponding to the shaft hole 12 and the extrusion platform 21 is provided with a plane groove 121 that engages with the extrusion platform 21. When the extrusion platform 21 is located in the plane groove 121, it is in the closed state or locked state of the hinge. The upper clamp 10 and the lower clamp 20 are made of plastic or metal material with a certain deformation reset effect. When the base 1 is rotated to the plane groove 121, it is separated from the extrusion platform 21. When the upper and lower clamps 10 and 20 are in a state of deformation, the extrusion platform 21 on the shaft 2 squeezes the shaft hole 12, and the shaft hole 12 is deformed to a certain extent. At the same time, the upper and lower clamps 10 and 20 are also in a deformed state. Since the openings of the upper and lower clamps 10 and 20 are fixed to each other by the groove 201 and the fixing hook 101, and are fixed by the screws or rivets between the mounting holes 11 at the left and right ends and the shell, the shaft hole 12 is in a contracted clamping state, so that the shaft hole 12 tightly clamps the shaft 2 in the shaft hole 12. There is a certain damping feeling when the base 1 and the base 2 3 rotate. When the base 1 rotates to the plane slot 121 and contacts the extrusion platform 21, the base 1 automatically rotates to the closed state or locked state of the hinge under the reset force of the shaft hole 12.

[0029] like Figure 4 and Figure 6 As shown, at least four fixing holes 33 are provided on the base 2 3, and an arched opening 34 is provided below the fixing hole 33. The four fixing holes 33 are evenly arranged along the shape of the opening 34. The base 2 3 is fixed to the mobile phone housing or the mobile power supply housing by screws or rivets through the fixing holes 33. When the base 1 rotates, the base 2 3 will generate a certain pulling force. The material reduction design of the arched opening 34 is used to disperse the pulling force to the left and right sides of the base 2 3. In this way, the bracket fixed on the base 1 can rotate more stably, and it can also prevent the middle position of the base 2 3 from being pulled by the pulling force. The two sets of shaft hole ears 31 are raised structures, and a avoidance opening 32 of a certain depth is formed between the two sets of shaft hole ears 31. The avoidance opening 32 is provided to facilitate the rotation of the base 1. In this embodiment, the base 1 is the rotating end of the 3D fixed end of the base 2, wherein the base 2 3 is fixed on the mobile phone shell or the mobile power shell, and the base 1 is fixed on the bracket. The distance from the center of the shaft hole of the rotating shaft fixing hole on the shaft hole ear 31 to the bottom of the avoidance opening 32 is set to 0.65MM, so that the hinge is more stable when it rotates as a whole.

[0030] like Figure 1 As shown, the base 1 is a waist-shaped structure, and the mounting holes 11 are arranged near the left and right ends of the waist-shaped structure.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
