Description

Technical Field

[0001] This utility model relates to the field of mobile phone hinge technology, specifically, to a hinge structure for a rotating screen mobile phone. Background Technology

[0002] With the increasing popularity of foldable and rotating screen phones, the hinge structure needs to simultaneously meet the requirements of smooth rotation, multi-angle hovering, and long-term durability.

[0003] Traditional hinges often use multiple sets of torque modules stacked together. After long-term use, spring fatigue leads to a decrease in torque, making it impossible for the screen to hover stably. The rotation process lacks segmented damping control, resulting in a stiff feel when opening and closing the screen. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a rotating screen mobile phone hinge structure. It solves the problems that traditional hinges often use multiple sets of torque modules stacked together, which lead to spring fatigue and torque reduction after long-term use, resulting in the screen being unable to hover stably. The lack of segmented damping control during the rotation process also results in a stiff feel when opening and closing the screen.

[0005] To achieve the above objectives, this utility model provides a rotating screen mobile phone hinge structure, including an upper cover and a bottom plate. The upper cover and the bottom plate are respectively provided with a first circular opening and a second circular opening. A shaft is provided in the first circular opening and is rotatably connected to the upper cover. A fixing plate is provided in the second circular opening of the bottom plate. The lower end of the shaft extends into the fixing plate. A guide block is provided on the fixing plate. A connecting hole is provided in the guide block and a fixing pin is provided in the connecting hole. Two spring pins are fixedly connected to the guide block. One end of the two spring pins opposite to the guide block is fixedly connected to the fixing block. A spring is sleeved on each of the two spring pins. The two ends of the spring abut against the guide block and the fixing block respectively to provide elastic preload.

[0006] Preferably, a connecting shaft is fixedly connected to the fixing block, a pushing block is fixedly connected to the connecting shaft, and an opening is provided on the upper cover, through which the connecting shaft passes, and the opening is gourd-shaped.

[0007] Preferably, the fixing plate is provided with a protrusion, the guide block is provided with a limiting groove that cooperates with the protrusion, the side wall of the limiting groove abuts against the protrusion, the protrusion is provided with a pin hole, and the lower end of the fixing pin is disposed in the pin hole.

[0008] Preferably, the upper cover has two symmetrically arranged No. 1 mounting holes, and the bottom plate has two symmetrically arranged No. 2 mounting holes, with rivets provided in both the No. 1 and No. 2 mounting holes.

[0009] Preferably, the top cover, fixing plate, bottom plate, shaft, fixing pin and rivet are made of stainless steel; the guide block is made of wear-resistant plastic; the spring is made of high-elasticity metal; and the fixing block, connecting shaft and pushing block are made of corrosion-resistant stainless steel.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In the initial stage of rotation, the spring provides constant preload through the fixed block to ensure smooth screen opening and closing. After the 4° rotation, the push block enters the circular end of the gourd-shaped opening, and the spring is compressed a second time to generate peak damping, achieving precise hovering and locking to prevent screen shaking.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-5This embodiment provides a rotating screen mobile phone hinge structure, including an upper cover 1 and a bottom plate 3. Considering that traditional hinges often use multiple sets of torque modules stacked together, after long-term use, spring fatigue leads to a decrease in torque, the screen cannot be stably suspended, the rotation process lacks segmented damping control, and the screen opening and closing feels stiff, the upper cover 1 and the bottom plate 3 are respectively provided with a first circular opening and a second circular opening. A shaft 4 is provided in the first circular opening, and the shaft 4 is rotatably connected to the upper cover 1. A fixing plate 2 is provided in the second circular opening of the bottom plate 3. The lower end of the shaft 4 extends into the fixing plate 2. A guide block 7 is provided on the fixing plate 2. A connecting hole is provided in the guide block 7, and a fixing pin 6 is provided in the connecting hole. Two spring pins 8 are fixedly connected to the guide block 7. One end of the two spring pins 8 opposite to the guide block 7 is fixedly connected to a fixing block 10. A spring 5 is sleeved on each of the two spring pins 8. The two ends of the spring 5 abut against the guide block 7 and the fixing block 10 respectively to provide elastic preload.

[0015] In summary, the improvement of this embodiment lies in: In the initial stage of rotation, the spring 5 provides constant pre-pressure through the fixed block 10 to ensure smooth screen opening and closing. After the stroke is advanced by 4°, the push block 12 enters the circular end of the gourd-shaped opening 101. The spring 5 is compressed a second time to generate peak damping, achieving precise hovering and locking, and preventing screen shaking.

[0016] Based on the above, other structures also need to be disclosed in detail, such as: Please see Figure 2 and Figure 3 In order to facilitate the pushing of the compression spring 5, a connecting shaft 11 is fixedly connected to the fixed block 10, and a pushing block 12 is fixedly connected to the connecting shaft 11. An opening is provided on the upper cover 1, through which the connecting shaft 11 passes. The opening is gourd-shaped, and the pushing block 12 moves along the groove of the gourd-shaped opening 101.

[0017] Please see Figure 2 and Figure 3 In order to facilitate the rotation of the fixed plate 2, the fixed plate 2 is provided with a protrusion. The guide block 7 is provided with a limiting groove that cooperates with the protrusion. The side wall of the limiting groove abuts against the protrusion. The protrusion is provided with a pin hole. The lower end of the fixing pin 6 is set in the pin hole. The cooperation between the limiting groove on the guide block 7 and the protrusion facilitates the rotation of the fixed plate 2.

[0018] Please see Figures 1 to 3 In order to install the upper cover 1 and the base plate 3 together, two No. 1 mounting holes are symmetrically opened on the upper cover 1 and two No. 2 mounting holes are symmetrically opened on the base plate 3. Rivets 9 are provided in the corresponding No. 1 and No. 2 mounting holes, and the upper cover 1 and the base plate 3 are installed together by the rivets 9.

[0019] Please see Figures 1 to 3The top cover 1, fixing plate 2, bottom plate 3, shaft 4, fixing pin 6 and rivet 9 are made of stainless steel, specifically SUS304 stainless steel; the guide block 7 is made of wear-resistant plastic, specifically POM; the spring 5 is made of high-elasticity metal, specifically SWP; the fixing block 10, connecting shaft 11 and push block 12 are made of corrosion-resistant stainless steel, specifically SUS316L stainless steel.

[0020] In summary, the working principle of this solution is as follows: When the phone screen is rotated, the push block 12 moves along the groove of the gourd-shaped opening 101. In the initial stage of rotation, the spring 5 provides constant pre-pressure through the fixed block 10 to ensure smooth opening and closing of the screen. After the stroke is advanced, the screen rotates 4° and the push block 12 enters the circular end of the gourd-shaped opening 101. The spring 5 is compressed a second time to generate peak damping, achieving precise hovering and locking to prevent the screen from shaking.
