Description

Technical Field

[0001] The invention relates to the technical field of hinges, and in particular to a hinge with adjustable torsion. Background Art

[0002] The torque in the hinge is generally generated by the elastic element arranged on it, specifically, the elastic force of the elastic element is used to prevent the hinge from rotating, thereby realizing the conversion of elastic force into torque; or by sleeved a number of springs on the hinge shaft, the friction of the springs on the hinge shaft prevents the hinge from rotating, thereby realizing the conversion of friction into torque. As electronic products develop towards miniaturization, lightness, and thinness, the supporting hinges are also required to develop towards miniaturization, which makes the space on the hinge for loading elastic elements or springs smaller and smaller. The outer diameter of the springs on the existing hinge shaft is greater than 3mm. When the loading space is less than 3mm, it is impossible to use multiple springs to adjust the torque. Therefore, the applicant proposes a hinge with adjustable torque to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a hinge with adjustable torsion to solve the above problems.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] It comprises a first hinged component and a second hinged component which are hinged to each other, wherein the first hinged component is provided with a sliding groove, and further comprises

[0006] A sliding component, slidably connected in the sliding groove;

[0007] A connecting component, one end of which is connected to the sliding component, and the other end of which is connected to the second hinge component, and when the second hinge component rotates, the connecting component is driven to make the sliding component slide along the sliding groove;

[0008] And an elastic component is arranged between the first hinge component and the sliding component; one end of the elastic component is fixedly connected to the first hinge component, and the other end elastically contacts the sliding component; or one end of the elastic component is fixedly connected to the sliding component, and the other end elastically contacts the first hinge component, and the friction force caused by the elastic contact hinders the sliding component from sliding in the sliding groove, thereby converting it into the torque of this hinge.

[0009] Furthermore, the first hinged component is provided with a hinged concave arc portion; the second hinged component is provided with a hinged convex arc portion matching the hinged concave arc; the hinged concave arc portion is provided with a travel slot; the hinged convex arc portion is provided with a travel block matching the travel slot.

[0010] Furthermore, a self-locking portion is provided on the first hinge component or the sliding component.

[0011] Furthermore, the sliding groove is a T-shaped groove, and a bearing boss is provided at the midline of the sliding groove.

[0012] Furthermore, a connecting slot is provided on the bearing boss, one end of which extends to the hinge of the first hinge component; and the connecting component is arranged in the connecting slot.

[0013] Furthermore, the bearing boss is provided with a placement groove, and the placement groove is provided with a notch communicated with the sliding groove; the elastic component is arranged in the placement groove.

[0014] Furthermore, the connecting component is a connecting rod, one end of which is connected to the sliding component via a bolt, and the other end of which is connected to the second hinged component via a fixing pin.

[0015] Furthermore, the elastic component includes at least one elastic element, a connecting piece and a contact portion; the connecting piece is used to support the elastic element; and the contact portion is arranged at the other end of the connecting piece relative to the elastic element.

[0016] Furthermore, the contact portion is a roller.

[0017] Furthermore, it also includes a fixing component; the fixing component covers the upper part of the hinge of the first hinge component and the second hinge component, and is connected to the first hinge component through bolts, so as to constrain the sliding of the second hinge component and the first hinge component.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Solve the problem that the hinge cannot increase torque in a small space. Compared with the existing method of using a spring sleeve on the hinge shaft to generate torque, this hinge generates friction through an elastic component and converts the friction into the torque of this hinge. It can be implemented in a smaller space (the space height is less than 3mm), so as to achieve the purpose of increasing torque in a small space, eliminate the phenomenon that the torque cannot be increased due to the space being less than 3mm, and can adjust the specifications of different torques by adjusting the spring specifications of the elastic element.

[0020] 2. Smooth rotation. The width of the sliding groove is 0.05mm larger than the width of the sliding component; the reserved 0.05mm gap can ensure that the sliding component slides smoothly in the sliding groove without getting stuck, making the hinge rotate more smoothly.

[0021] 3. Realize the self-locking function. A self-locking part is provided on the inner side of the lower part of the sliding groove. When the contact part in the elastic component passes through the self-locking part, it will be locked in the position to realize the self-locking function. By adjusting the number and position of the self-locking part, the self-locking of the hinge at different rotation angles can be realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] One end of the connecting component 400 is connected to the sliding component 300, and the other end is connected to the second hinge component 200. When the second hinge component 200 rotates, the connecting component 400 is driven to make the sliding component 300 slide along the sliding groove 110. In this embodiment, the connecting component 400 is a connecting rod, which is arranged in the connecting groove 131. One end of the connecting component 400 is connected to the sliding component 300 through a bolt, and the other end is connected to the second hinge component 200 through a fixing pin 410.

[0038] The elastic component 500 is arranged in the placement groove 132 of the first hinge component 100, and the elastic component 500 includes at least one elastic element 510, a connecting piece 520 and a contact portion 530; in this embodiment, the placement groove 132 is provided with a bearing groove 134 and a first alignment column 135 corresponding to the number of the elastic element 510, and the elastic element 510 is a spring, and three of them are provided; the front end of the connecting piece 520 is provided with a second alignment column 521 corresponding to the number of the elastic element 510 and used for aligning the elastic element 510, and the rear end is provided with an alignment seat 522, and the alignment seat 522 is located in the notch 133; the contact portion 530 is a roller, and is sleeved on the alignment seat 522, which can convert the friction force caused by the elastic element 510 on the sliding component 300 into rolling friction, thereby increasing the service life and making the hinge folding feel smoother;
