[0002] For foldable portable electronic terminals, such as mobile phones and laptops, there is a requirement for heavy opening and light closing, that is, the opening process from folding to the use angle (such as flattening) requires a heavier feel, and a lighter feel in the closing direction. This can be achieved by means of a reed tube. The reed tube clamps the shaft to generate a resistance torque. The reed tube is an open tube. By selecting the opening position, it can generate different clamping forces on the shaft in the positive and negative rotation directions to generate different resistance torques. However, the output torque of this torque output structure is relatively large. When it is required to have an automatic reset function in the flattened state, the driving torque of the reset mechanism cannot be made relatively large, which will affect the working effect of this reset mechanism.

[0020] Refer to the accompanying drawings. The utility model provides a hinge for a foldable portable electronic terminal, including an axis 1 and a connection structure, wherein the connection structure is used to connect the hinge and one of the two relatively rotating parties in the foldable portable electronic terminal (such as one of the shells in a foldable mobile phone). The hinge is provided with a first resistance torque providing mechanism and a second reset drive torque providing mechanism, wherein the first resistance torque providing mechanism provides different first resistance torques and second resistance torques for the rotation of the foldable portable electronic terminal in the opening direction and the closing direction, respectively, and the second reset drive torque providing mechanism provides a driving torque that overcomes the resistance torque within the reset drive angle range, and the first resistance torque providing mechanism is also provided with a resistance adjustment matching structure, and within the reset drive angle range, the first resistance torque and the second resistance torque are reduced.

[0021] In this embodiment, the first resistance torque providing mechanism uses a spring tube 2, which is provided with an opening 21. The spring tube 2 clamps the shaft, and the first resistance torque and the second resistance torque are different by adjusting the position of the opening 21; the second reset drive torque providing mechanism uses a cam pair and is pressed by an elastic element 4, wherein the first cam 31 is connected to the shaft 1 and is synchronized with the shaft 1 in the rotation direction, wherein the second cam 32 is sleeved on the shaft 1 and can rotate relative to the shaft 1, and the first cam 31 is also sleeved on the shaft 1 and is connected through flat position matching and rotates synchronously, and the elastic element can be a plurality of butterfly springs sleeved on the shaft 1. Through the matching of the first cam 31 and the second cam 32, for example, when the reset drive angle range is downhill matching, under the drive of the elastic element 4, the first cam 31 is driven to rotate, and the shaft 1 also rotates synchronously.

[0022] In this embodiment, the resistance adjustment cooperation structure includes a first non-circular portion 11 with a reduced diameter arranged on the shaft 1, and a second protruding portion 22 is arranged inside the reed tube 2. The angle range corresponding to the contact between the second protruding portion 22 and the first non-circular portion 11 corresponds to the reset drive rotation angle range. In the reset drive angle range, the first resistance torque and the second resistance torque are reduced by the cooperation between the second protruding portion 22 and the first non-circular portion 11.

[0023] In this embodiment, the first non-circular portion 11 is a plane on the shaft 1 that covers the length of the spring switch 2 .

[0024] In this embodiment, the foldable portable electronic terminal is a dual-axis foldable portable electronic terminal, the hinge is provided with two parallel axes 1, the reed pipe 2 on the first axis and the reed pipe 2 on the second axis are connected together, and are located at both ends of the same component 20, the axis 1 is the rotating side and the reed pipe 2 is regarded as the stationary side, the first axis and the second axis are connected with the connecting structure, and the connecting structure can be a connecting arm 5, and the connecting arm 5 can be connected to one side of the housing of the foldable mobile phone. The end of the connecting arm 5 is provided with a connecting flat hole 51, and the connecting flat hole 51 is sleeved on the axis 1, and the first cam 31 can be provided at the end of the connecting arm 5 and surround the end surface of the hole facing the second cam, so as to be connected to the axis 1. The second cam 32 on the first axis and the second axis is also connected together to remain stationary relative to the axis 1.

[0025] In this embodiment, the biaxial foldable portable electronic terminal is a foldable portable electronic terminal that can be rotated to open to flatten, and the reset drive is aimed at the flattened position as the reset target, and is automatically driven to the flattened state in the opening rotation direction and the closing rotation direction within the angle range close to the flattening, wherein, Figure 7 , label S is the reset starting point, and the reset driving angle can be around 10°.

[0026] In this embodiment, the operating feeling of heavy opening and light closing is achieved, that is, the first resistance torque in the rotation stroke in the opening direction is greater than the second resistance torque in the rotation stroke in the closing direction. For the first resistance torque to be greater than the second resistance torque, the opening 21 can be set on the side that has an opening tendency in the closing rotation direction, while in the opening rotation direction, the opening 21 has a tendency to shrink.

[0027] Therefore, although the clamping of the spring tube 2 on the shaft 1 causes its resistance torque to be relatively large in both the closing direction and the opening direction, the adjustment mechanism can be adjusted so that in the reset drive stage, the first resistance torque and the second resistance torque can be reduced through the cooperation of the second protruding portion 22 and the first non-circular portion 11 without adding any additional structure, and within the reset drive angle range, the reduced rear end first resistance torque and the second resistance torque are not only smaller than the driving torque provided by the second reset drive torque providing mechanism, but the difference is obvious, thereby improving the reset performance and providing a clear hand feel.
