[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1 and Figure 2 As shown, the utility model discloses a composite rotating shaft, comprising: a first bracket 1, a first rotating shaft 2, a second bracket 3 and a second rotating shaft 4, wherein: the first rotating shaft 2 is arranged on the first bracket 1, and the first rotating shaft 2 can rotate along a first axis in space relative to the first bracket 1, the second bracket 3 is arranged on the first rotating shaft 2, and the second bracket 3 is driven to rotate by the first rotating shaft 2, and the second rotating shaft 4 is arranged on the second bracket 3, and the second rotating shaft 4 can rotate along a second axis in space relative to the second bracket 3, and the plane where the first axis is located is perpendicular to the plane where the second axis is located. In this embodiment, the first bracket 1 and the second bracket 3 are arranged to respectively support the first rotating shaft 2 and the second rotating shaft 4, so that the first rotating shaft 2 and the second rotating shaft 4 can respectively rotate along two different axes, and can realize composite rotation in two axes in space, which meets the design requirements of the opening and closing rotation of the screen and the bottom plate of the laptop computer, as well as the rotation of the screen itself.

[0030] Reference Figure 3As shown, the first bracket 1 has a connecting surface 11 and a supporting surface 12, and the connecting surface 11 and the supporting surface 12 are bent and connected to form an "L"-shaped bending structure. A through hole for the first rotating shaft 2 to pass through is opened on the connecting surface 11, and the end of the first rotating shaft 2 is bent toward the outer circumference after passing through the shaft hole, so that the end of the first rotating shaft 2 is riveted and fixed to the first bracket 1.

[0031] Specifically, after the first rotating shaft 2 passes through the through hole, a stop piece 5 is sleeved on the first rotating shaft 2, and the stop piece 5 rotates with the first rotating shaft 2. The stop piece 5 is provided with a stop protrusion 51 protruding toward the first bracket 1, and a stop groove 13 cooperating with the stop protrusion 51 is provided on the first rotating shaft 2. When the stop protrusion 51 enters the stop groove 13, the resistance to rotating the first rotating shaft 2 can be increased, thereby forming a fixed-angle rotation stop of the first rotating shaft 2 on the first bracket 1. For example, when using a laptop computer, when the computer screen is rotated to 90°, the stop protrusion 51 falls into the stop groove 13. At this time, the rotation resistance of the first rotating shaft 2 is increased, so that the computer screen can be relatively fixed at this angle position, which is convenient for users to use.

[0032] Specifically, in order to enable the stop protrusion 51 to be moved out of the stop groove 13, the stop member 5 needs to be able to move in the axial direction equivalent to the first bracket 1, and a certain moving space needs to be reserved. In order to prevent the stop member 5 from moving randomly in the moving space, in this embodiment, an elastic member 6 is also sleeved on the first rotating shaft 2, and the elastic member 6 abuts against the stop member 5. The elastic member 6 provides the stop member 5 with elastic moving space and elastic supporting force in the axial direction, so that it can provide the stop member 5 with moving space in the axial direction, and support the stop member 5 to prevent it from moving freely in the axial direction.

[0033] Specifically, after the first rotating shaft 2 passes through the through hole, a limiting member 7 is sleeved on the first rotating shaft 2. The limiting member 7 rotates with the first rotating shaft 2. The limiting member 7 has a limiting protrusion 71 extending outward. A limiting block 14 capable of resisting the rotation of the limiting member 7 is provided on the supporting surface 12 of the first bracket 1. The abutment and cooperation between the limiting protrusion 71 and the limiting block 14 can limit the rotation angle of the first rotating shaft 2 equivalent to the first bracket 1.

[0034] Reference Figure 4As shown, before the first rotating shaft 2 passes through the through hole, a guide member 8 is sleeved on the first rotating shaft 2, and a guide block 81 is provided on the guide member 8 and protrudes toward the first bracket 1. A guide groove 15 is also provided on the first bracket 1, and the guide block 81 can be inserted into the guide groove 15 and slide in the guide groove 15. Through the cooperation between the guide block 81 and the guide groove 15, not only can the relative connection position of the first rotating shaft 2 and the first bracket 1 be limited, but also it can be ensured that no axis deviation occurs during relative rotation.

[0035] Reference Figure 5 As shown, a platform plane is provided at the connection position between the first rotating shaft 2 and the second bracket 3, and the platform plane can support the second bracket 3. Threaded holes are opened at corresponding positions of the platform plane and the second bracket 3, and bolts are arranged to pass through the threaded holes in the second bracket 3 and the platform plane in turn, so that the second bracket 3 and the first rotating shaft 2 are locked and connected by the bolts.

[0036] Specifically, in this embodiment, the first rotating shaft 2 is detachably connected to the first bracket 1 and the second bracket 3. On the one hand, it is convenient for the separate production of each part and can improve the production efficiency. On the other hand, when one of the parts is damaged, it can also be replaced separately.

[0037] In this embodiment, the second rotating shaft 4 includes two shafts arranged on the second bracket 3, and the two shafts are arranged on the same straight line. A shaft frame 31 for the two shafts to pass through is arranged on the second bracket 3. Connecting plates are sleeved on the two shafts, and the two connecting plates are arranged on the same plane. The two connecting plates can be connected to the computer screen bracket through the two connecting plates, and the computer screen bracket is driven to rotate by the two shafts to ensure stability during rotation.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
