[0025] Example:

[0026] See also Figure 1-5 , the utility model provides a technical solution:

[0027] A hub device includes two bases 21, an arc-shaped mounting member 22 and a torsion assembly 23. The two bases 21 are symmetrically arranged, and the arc-shaped mounting member 22 is arranged between the two bases 21. An installation space 211 is opened on the side close to the two bases 21. A first track 212 is opened inside the installation space 211 of the two bases 21. The base 21 includes a mounting plate 213, a stopper 214 and a half body 215. The two mounting plates 213 are located at the front end of the side away from the base 21, the two stoppers 214 are located at the rear end of the first track 212, and the two half bodies 215 are connected to the two mounting plates. The adjacent sides of the plates 213 are connected and fixed. The front ends of the two bases 21 are jointly provided with an assembly plate 216. A baffle 217 is fixed on the upper side of the assembly plate 216. The baffle 217 is clamped inside the limit stop groove. Positioning notches 218 are opened on the left and right sides of the assembly plate 216. Assembly protrusions 219 are fixed on the front sides of the two half bodies 215. The positioning notches 218 are clamped with the assembly protrusions 219. Symmetrical auxiliary protrusions 210 are fixed at the lower end of the first track 212 on the adjacent side of the two bases 21. The auxiliary protrusions 210 are slidably set inside the auxiliary track 227.

[0028] The arc-shaped mounting member 22 includes an arc-shaped portion 221 and a mounting portion 222. The mounting portion 222 can be used to mount the hub to the object to be supported (not shown) by setting a bracket, so that when the hub 20 is unfolded, the object to be supported can be maintained at a specific angle. Specifically, the object to be supported can be a tablet or a display, and the hub allows the object to be supported to be placed on a desktop, on the ground, or on any other plane, at an angle that is convenient for the user to view. In this embodiment, the base 21 has two mounting plates 213 for assembly with the object to be supported. In addition, the arc-shaped portion 221 can be formed by a semicircular body or an arc-shaped plate, which is not included in this article. Figure 2 and Figure 3 Due to illustration limitations, the arcuate portion 221 is located between the two bases, the mounting portion 222 is located at the rear end of one side adjacent to the two bases 21, the arcuate portion 221 is located at the front end of the mounting portion 222, and second rails 223 are defined on both sides of the mounting portion 222. The front end of the second rail 223 is a head end 224, and the rear end of the second rail 223 is a tail end 225. Protrusions 226 are fixed to the left and right sides of the arcuate portion 221, and auxiliary rails 227 are defined on the left and right sides of the arcuate portion 221, located below the protrusions 226.

[0029] The two torsion assemblies 23 are respectively arranged at the two ends of the two bases 21. The torsion assemblies 23 include a shaft 231, a torsion providing member 232, and a connecting rod 233. The ends of the two shafts 231 that are close to each other are fixed to the side away from the half body 215. The two connecting rods 233 are rotatably arranged on the outside of the shaft 231. The rod walls of the two connecting rods 233 are located at one end of the connecting rod 233 and the torsion providing member 232 is fixed. The sides of the two connecting rods 233 that are close to each other are fixed with connecting protrusions 234. The two connecting protrusions 234 are respectively slidably connected to the second rail 223. The connecting rod 233 and the torque providing member 232 are respectively provided with a first protrusion 235 on the opposite side. The first protrusion 235 and the second protrusion 236 are respectively formed on opposite sides of the connecting rod 233 and the torque providing member 232. The first protrusion 235 fits in the first concave 237, and the second protrusion 236 fits in the second concave 238. In this application, the two torsion assemblies 23 are symmetrically arranged on opposite sides of the arc-shaped mounting member 22. When the arc-shaped mounting member 22 rotates relative to the base 21, the torsion assemblies 23 both apply torque to the arc-shaped mounting member 22, so that the torsion on both sides of the arc-shaped mounting member 22 is equal. This is not achieved by applying torque to only one side of the arc-shaped mounting member 22 via a single torsion assembly 23, thereby increasing the structural stability of the hinge 20 during operation. Furthermore, the hinge 20 has a simple structure. During assembly, the connecting rod 233 is arranged on two opposite sides of the base 21. The connecting rod 233 contacts the torque providing member 232 and connects to the arc-shaped mounting member 22 at opposite ends of the connecting rod 233, making assembly of the hinge 20 easier.

[0030] The arc-shaped portion 221 of the arc-shaped mounting member 22 is in a closed state when it is received in the base 21 (eg Figure 4 As shown), the arc-shaped mounting member 22 is in the open state when it rotates away from the base 21 (as shown Figure 5As shown in the figure, the torque assembly 23 is used as an example. Assuming that the arc-shaped mounting member 22 is closed, the connecting protrusion 234 of the linkage rod 233 is located at the rear end 225 of the second track 223. When the hinge is opened, the mounting portion 222 of the arc-shaped mounting member 22 is subjected to force and displaced relative to the base 21, causing the arc-shaped portion 221 to rotate along the first track 212. This, in turn, causes the connecting protrusion 234 of the linkage rod 233 to displace, moving the connecting protrusion 234 from the rear end 225 toward the front end 224. During the movement of the connecting protrusion 234, the arc-shaped mounting member 22 continuously senses the torque generated between the linkage rod 233 and the torque-providing member 232, providing torque to the arc-shaped mounting member 22 through the connecting protrusion 234. When the arc-shaped mounting member 22 is no longer subjected to force, the torque temporarily positions the arc-shaped mounting member 22 at a specific angle. When the arc-shaped mounting member 22 is again subjected to a torque greater than or equal to the torque, the angle of the arc-shaped mounting member 22 is changed. The arc-shaped mounting member 22 continues to rotate until the connecting protrusion 234 is located at the head end 224, which is the maximum rotation angle of the arc-shaped mounting member 22. If the hinge is restored to the closed state, the mounting portion 222 of the arc-shaped mounting member 22 rotates in the opposite direction, and drives one end of the connecting rod 233 to move in the opposite direction, so that the connecting protrusion 234 moves from the head end 224 to the tail end 225 until the connecting protrusion 234 is located at the tail end 225, and the hinge is restored to the closed state.

[0031] The two arc-shaped portions 221 are both slidably disposed inside the first track 212 . The length of the base 21 and the linkage rod 233 does not need to be increased according to the length of the first track 212 , thereby reducing the volume occupied by the hinge when installed on the object to be supported.

[0032] The torque assembly 23 is symmetrically arranged on both sides of the arc-shaped mounting member 22, so that the torque felt by the arc-shaped mounting member 22 during rotation is more uniform and the force is consistent compared to a conventional hinge device, thereby improving the overall structural stability of the hinge device. The connecting rod 233 in the present application is arranged on the relatively outer side of the base 21, instead of being arranged in the installation space like a conventional hinge device, to improve the problem of the conventional hinge device being difficult to assemble.

[0033] The arc portion 221 has two protrusions 226 located on the first track 212. The base 21 has a stopper 214 located within the first track 212 to determine the range of movement of the arc-shaped mounting member 22. When the protrusions 226 move on the first track 212, the stopper 214 contacts the protrusions 226, limiting the displacement range of the protrusions 226 on the first track 212, thereby limiting the rotation angle of the arc portion 221.

[0034] The base 21 has symmetrically arranged half bodies 215, each corresponding to the other. The first rails 212 are disposed within each half body 215. The arc-shaped mounting member 22 can be assembled with the half bodies 215 after being assembled with the half bodies 215, facilitating assembly of the base 21 and the arc-shaped mounting member 22 before forming the mounting space 211.

[0035] The base 21 has a connecting plate 216 connecting the two halves 215, the connecting plate 216 shown in the drawings is only illustrative and is not intended to limit the position of the connecting plate 216. The connecting plate 216 has a baffle plate 217 extending towards the arc-shaped mounting member 22 and limiting the range of motion of the arc-shaped mounting member 22. The baffle plate 217 is located on the rotation track of the arc-shaped mounting member 22. When the arc-shaped portion 221 of the arc-shaped mounting member 22 rotates along the first track 212 towards the baffle plate 217, the arc-shaped portion 221 is blocked by the baffle plate 217 to avoid excessive rotation of the arc-shaped portion 221.
