[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0035] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0036] See Figures 1 to 3 An embodiment of the present invention provides a hinge structure with damping, comprising a rotating shaft 1 and a rotating shaft screw 2. Rotating brackets 3 are provided at both ends of the rotating shaft 1. A first through-hole 11 is defined along the length of the rotating shaft 1. Second through-holes 31 are defined on the rotating brackets 3 at positions corresponding to the first through-holes 11, corresponding to the second through-holes 31. At least one of the second through-holes 31 is threaded. The rotating shaft screws 2 are inserted into the second through-holes 31 of the rotating brackets 3 at both ends of the rotating shaft 1, and the rotating shaft screws 2 pass through the first through-holes 11. A damping mechanism is mounted on the rotating brackets 3 to limit the rotation of the rotating shaft 1. The damping mechanism enables the flip door cover to stop at any position within the effective rotation angle.

[0037] Specifically, the damping mechanism includes a force-applying member 4 that applies force to the end of the rotating shaft 1. The rotating bracket 3 also has a mounting hole 32, into which the force-applying member 4 is secured. Placing the force-applying member 4 in the mounting hole 32 facilitates installation and helps reduce the size of the mechanism.

[0038] The force-applying member 4 includes an elastic force arm 41, one end of which is fixed on the rotating bracket 3, and the free end of the elastic force arm 41 extends toward the end of the rotating shaft 1, and the free end of the elastic force arm 41 contacts the end of the rotating shaft 1. A protrusion 42 is provided at the contact point between the free end of the elastic force arm 41 and the end of the rotating shaft 1. The elastic force arm 41 applies its elastic force to the end of the rotating shaft 1, thereby achieving a damping effect. The upper damping mechanism uses an elastic member to apply force to the end of the rotating shaft 1, increasing the friction when the rotating shaft 1 moves, thereby achieving a damping effect. The damping mechanism is mainly composed of an elastic force-applying member 4, and the above scheme is simple in structure and can be produced by general machinery manufacturers.

[0039] A screw locking mechanism is also provided, comprising a gear 5 and a resilient claw 6. The gear 5 is coaxially fixed to the shaft screw 2. One end of the resilient claw 6 is fixed to the rotating bracket 3, and the free end of the resilient claw 6 is inserted between the teeth of the gear 5. The screw locking mechanism secures the shaft screw 2, preventing it from loosening due to friction between the shaft screw 2 and the rotating shaft 1. Specifically, the screw locking mechanism locks the shaft screw 2 by engaging the resilient claw 6 with the gear 5, thereby preventing the shaft screw 2 from loosening. To remove the shaft screw 2, simply move the resilient claw 6 away from the gear 5 to disengage it.

[0040] The end of the rotating shaft 1 is provided with a protruding ring 12, which is coaxial with the rotating shaft 1 and contacts the rotating bracket 3. The protruding ring 12 can reduce the contact area between the rotating shaft 1 and the rotating bracket 3, helping to prevent abnormal noise caused by the large contact area.

[0041] The rotating shaft screw 2 is in a truncated cone shape, which can reduce the contact area between the rotating shaft 1 and the rotating shaft screw 2, thereby preventing the rotating shaft screw 2 from rotating and generating abnormal noise when the rotating shaft 1 rotates.

[0042] This technical solution features a simple structure, effectively saving costs and improving production efficiency. Composed of relatively simple parts, it can be manufactured by general machinery manufacturers, eliminating the need for specialized hinge manufacturers to design and manufacture. A simple damping mechanism allows the flip door cover to stop at any position within the effective rotation angle, while a screw locking mechanism prevents the pivot screw 2 from loosening due to friction between the pivot screw 2 and the rotating shaft 1. Furthermore, by designing the pivot screw 2 as a truncated cone, reducing the contact area between the rotating shaft 1 and the pivot screw 2, and by providing a protruding ring 12, reducing the contact area between the rotating shaft 1 and the rotating bracket 3, abnormal noise is reduced or prevented, addressing the problem of wear and abnormal rotation noise associated with conventional locking screws.

[0043] See Figures 1 to 3 An embodiment of the present invention provides a device housing comprising a main body and a cover, wherein the main body and the cover are movably connected via the aforementioned damping hinge structure, and the rotating shaft 1 and the rotating bracket 3 are fixedly connected to the main body and the cover, respectively. This type of device housing can possess the advantages of the aforementioned damping hinge structure.

[0044] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Furthermore, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
