Description

Technical Field

[0001] This utility model relates to the field of rotating shaft technology, specifically a single-axis 360° rotating shaft. Background Technology

[0002] With the development of technology, various electronic products have emerged, bringing tremendous changes to people's lives. In particular, the use of computers has changed people's lifestyles and accelerated their pace of life. In order to improve the portability of devices and user experience, existing technologies often choose to make electronic devices such as laptops open and close 360°. In this process, the hinge is the core component in order to achieve the function of opening and closing the screen and the main body at multiple angles or even rotating 360 degrees.

[0003] It is generally known that mainstream devices capable of 360-degree rotation on the market generally adopt a dual-axis structure design. More specifically, a dual-axis design typically includes two independent rotating parts that work together through a complex linkage mechanism. In subsequent operation, the first set of rotating parts is responsible for the normal opening and closing of the screen, while the second set of rotating parts takes over and continues to complete the subsequent rotation after the screen has opened to a certain angle, such as from 180° to 360°.

[0004] While the aforementioned structure can meet the requirement of 360° rotation for electronic devices, it still has the following shortcomings. As is well known, a dual-axis structure needs to accommodate two independent rotating cores and their linkages. This inevitably leads to the rotating shaft module occupying more physical space in the width and thickness directions of the device. In order to accommodate this dual-axis structure, the existing technology has to widen the structure of the device body, which affects the user experience to some extent. Moreover, more shafts will increase the cost of materials and other equipment, making it unsuitable for widespread use. Utility Model Content

[0005] The purpose of this invention is to provide a single-axis 360° rotating shaft to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a single-axis 360° rotating shaft, comprising a shaft body, a first mounting bracket mounted on the shaft body, and an annular bracket sleeved on the shaft body, and a second mounting bracket fixedly connected to the annular bracket; a linkage unit is provided between the shaft body and the annular bracket to realize 360° rotational positioning of the first mounting bracket.

[0007] Furthermore, the linkage unit includes a gear fixedly connected to the shaft, and a rack fixedly connected to the inner wall of the ring frame, wherein the gear meshes with the rack; during the rotation of the first mounting frame, the shaft moves inside the ring frame through the cooperation of the gear and the rack.

[0008] Furthermore, an elastic positioning mechanism is provided on the side of the shaft away from the first mounting bracket.

[0009] Furthermore, the elastic positioning mechanism includes a nut, which is installed at the end of the shaft away from the first mounting bracket; a retaining ring is also provided between the nut and the ring bracket; and an elastic unit is also provided between the nut and the retaining ring.

[0010] Furthermore, the elastic unit includes a spring disposed between the retaining ring and the nut.

[0011] Furthermore, the elastic unit includes a torsion spring and a noise-reducing spring mounted on the shaft; the torsion spring is used to provide torsional cushioning, and the noise-reducing spring is used to reduce noise during rotation.

[0012] Furthermore, the shaft is connected to the first mounting bracket via an extension rod.

[0013] Furthermore, a connecting frame is also provided between the first mounting bracket and the extension rod.

[0014] Furthermore, a threaded section is provided at the end of the shaft away from the extension rod, and the nut is installed on the side of the shaft away from the extension rod through the threaded section.

[0015] Furthermore, both the first mounting bracket and the second mounting bracket are provided with locking slots.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: This single-axis 360° rotating shaft, through the cooperation of the shaft body, first mounting bracket, second mounting bracket, ring frame, and linkage unit, achieves 360° rotational positioning of the first mounting bracket during use. This is achieved by the shaft body moving within the ring frame via the linkage unit as the first mounting bracket rotates relative to the second mounting bracket. This effectively overcomes the problem of excessive physical space occupied by existing dual-axis structures, eliminating the need for additional widening of the device body structure, improving the compactness and portability of the device, and further enhancing the user experience. More specifically, the single-axis design significantly reduces material usage and the number of components, lowering production costs and making it suitable for widespread use.

[0021] Please see Figures 1-6 This utility model provides a technical solution: a single-axis 360° rotating shaft, including a shaft body 3, a first mounting bracket 1 mounted on the shaft body 3, and an annular bracket 4, which is sleeved on the shaft body 3 and a second mounting bracket 2 is fixedly connected to the annular bracket 4; a linkage unit is provided between the shaft body 3 and the annular bracket 4 to realize the 360° rotation positioning of the first mounting bracket 1.

[0022] Specifically, this single-axis 360° hinge includes a shaft body 3, on which a first mounting bracket 1 is mounted for connecting a part of the device, such as a screen. It also includes a ring frame 4, which is fitted onto the shaft body 3, and a second mounting bracket 2 is fixedly connected to the ring frame 4 for connecting another part of the device, such as the chassis. A linkage unit is provided between the shaft body 3 and the ring frame 4. This linkage unit achieves continuous 360° rotation and positioning of the first mounting bracket 1 relative to the second mounting bracket 2 through a mechanical structure, enabling the device to open and close in all directions. The single-axis design, replacing the traditional dual-axis structure, significantly reduces the space occupied by the hinge module in the width and thickness directions, making the device lighter and more portable. It also simplifies the number of components, reduces material costs and manufacturing complexity, and improves production efficiency and product reliability, making it suitable for electronic products requiring 360° rotation, such as laptops.

The gear 9 meshes with the rack 8. During the rotation of the first mounting frame 1, the shaft 3 moves inside the annular frame 4 through the cooperation of the gear 9 and the rack 8. More specifically, the movement of the shaft 3 is a composite movement of movement and rotation inside the annular frame 4. This achieves a 360° rotation trajectory for the first mounting frame 1.

[0024] In the embodiment provided by this utility model, an elastic positioning mechanism is provided on the side of the shaft 3 away from the first mounting bracket 1. The elastic positioning mechanism can provide a clear positioning feel when rotated to a specific angle, preventing the equipment from being over-rotated or loosened, and improving the stability and safety during use.

[0025] In the embodiments provided by this utility model, the elastic positioning mechanism includes a nut 5, which is installed at the end of the shaft 3 away from the first mounting bracket 1; a retaining ring 7 is also provided between the nut 5 and the ring bracket 4, and an elastic unit 6 is also provided between the nut 5 and the retaining ring 7. Through the cooperation of the nut 5 and the retaining ring 7, the preload of the elastic unit 6 can be easily adjusted to realize the customized adjustment of the rotational resistance and adapt to the opening and closing requirements of different equipment.

[0026] In the embodiment provided by this utility model, the elastic unit 6 includes a spring, which is disposed between the retaining ring 7 and the nut 5. When the shaft 3 rotates, the spring is compressed or released to generate elastic feedback, thereby meeting the user's needs.

[0027] In the embodiment provided by this utility model, the elastic unit 6 includes a torque spring 61 and a noise-dampening spring 62 mounted on the shaft 3. The torque spring 61 provides torsional buffering, and the noise-dampening spring 62 reduces noise during rotation. The torque spring 61 enhances the smoothness and controllability of rotation, preventing vibration when the equipment is flipped. Furthermore, the noise-dampening spring 62 effectively reduces operating noise and improves the user experience.

[0028] In the embodiment provided by this utility model, the shaft 3 is connected to the first mounting bracket 1 via an extension rod 31. The extension rod 31 provides additional installation space and flexibility, allowing the first mounting bracket 1 to be a certain distance from the shaft 3, adapting to the internal layout and design requirements of different equipment.

[0029] In the embodiment provided by this utility model, a connecting frame 10 is also provided between the first mounting frame 1 and the extension rod 31. The connecting frame 10 improves the rigidity and stability of the overall structure, prevents the connection from loosening or wearing due to frequent rotation, and improves the service life of the rotating shaft from the side.
