Description

Technical Field

[0001] This utility model relates to a hinge for use in portable electronic devices, such as mobile phones and laptops. Background Technology

[0002] Portable electronic devices, such as laptops, need to maintain a certain resistance torque during opening and closing to ensure tactile feedback or provide a free-stopping function. Some applications also require the torque to be released at a specific angle to achieve locking at that angle, and this release process should be completed within a small rotational travel. Currently, there are two main methods for achieving resistance torque in hinges: one is to use a reed clamping the shaft to provide resistance torque, and the other is to use a disc spring to axially press against an end face cam to provide pressure between the friction structures. For the former, the change in torque requires a considerable rotational travel; for the latter, the wear caused by friction between the cam surfaces has a significant impact on the lifespan of the cam control. Utility Model Content

[0003] The purpose of this invention is to provide a hinge that achieves rapid torque release in a simple manner, providing instantaneous torque release while avoiding wear between cam surfaces that could affect service life. Therefore, this invention adopts the following technical solution: A hinge for rapid torque release is characterized by comprising a first connecting member and a second connecting member, and a friction structure. The first connecting member and the second connecting member are rotatably connected by a shaft. The friction structure includes a friction shaft and a first groove and a second groove eccentric to the shaft. The first groove and the second groove intersect, and the friction shaft passes through the first groove and the second groove. The first groove and the second groove are respectively matched with the first connecting member and the second connecting member. The friction shaft is pressed against the groove wall of the first groove to form a friction fit. The hinge is also provided with an elastic component that provides pressure for the friction. The first groove is provided with a recess corresponding to the angle at which the torque needs to be released, so that the potential energy provided by the elastic component is rapidly released.

[0004] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions: The friction shaft is connected to the elastic component.

[0005] The first connector and the second connector are respectively provided with a first groove and a second groove.

[0006] The hinge is provided with two sets of friction structures. The two ends of the elastic component are respectively connected to the friction shafts in the two pairs of friction structures. The first groove of the first set of friction structures is matched with the first connecting member, and the first groove of the second set of friction structures is matched with the second connecting member.

[0007] The rotating connection structure formed by the first connector and the second connector is a segment of the hinge.

[0008] The elastic component is a wire spring or a leaf spring.

[0009] Both the first connector and the second connector are plate-shaped parts, or parts with a plate as the main body.

[0010] The hinge is a hinge in a portable electronic device, including mobile phones and laptops, which are portable electronic devices that can be folded and unfolded.

[0011] Because of the technical solution of this utility model, this utility model not only has a simple structure, but also can provide the required friction torque and can quickly release torque and switch quickly during operation. In terms of control structure, there is almost no wear, and the problem of excessive wear of control surface caused by previous cam control will not occur. Attached Figure Description

[0017] Referring to the accompanying drawings, this utility model provides a hinge for rapid torque release, comprising a first connecting member 1, a second connecting member 2, and a friction structure. The first connecting member 1 and the second connecting member 2 are rotatably connected by a shaft 3. The friction structure includes a friction shaft 40 and a first groove 41 and a second groove 42 eccentric to the shaft 3. The first groove 41 and the second groove 42 intersect, and the friction shaft 40 passes through the first groove 41 and the second groove 42. The first groove 41 and the second groove 42 are respectively assigned to the first connecting member 1 and the second connecting member 2, which can be achieved by directly setting corresponding grooves on the first connecting member 1 and the second connecting member 2. The friction shaft 40 is pressed against the groove wall of the first groove 41 to form a friction fit. The hinge also includes an elastic component 5 that provides pressure for the friction. The first groove 41 has a recess 43 corresponding to the angle at which the torque needs to be released, so that the potential energy provided by the elastic component 5 is rapidly released. The elastic component 5 can be a wire spring or a leaf spring, such as the wire spring or leaf spring with a certain degree of curvature in this embodiment. The friction shaft 40 and the elastic component 5 are connected.

[0018] A preferred embodiment involves providing two sets of friction structures. The two ends of the elastic component 5 are respectively connected to the friction shafts 40 in the two pairs of friction structures. The first connecting member 1 has a first groove 41 in the first set of friction structures, and a second groove 42 in the first set of friction structures is located on the second friction plate 2. The second connecting member 2 has a first groove 41 in the second set of friction structures, and a second groove 42 in the second set of friction structures is located on the first friction plate 1. This significantly increases the friction torque without increasing the structural complexity, and the installation of the elastic component 5 is also optimally addressed.

[0019] Both the first connector 1 and the second connector 2 are plate-shaped parts, or parts with a plate as the main body.

[0020] If necessary, several first connectors 1 and second connectors 2 can be stacked alternately to provide a greater frictional torque. The rotating connection structure formed by the first connector 1 and the second connector 2 can be a segment of the hinge or the entire hinge.

[0021] The hinge is a hinge in a portable electronic device, including mobile phones and laptops, which are portable electronic devices that can be folded and unfolded.
