[0035] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.
[0036] like Figure 1 to Figure 2 As shown, an angular connector with a biaxial hinge structure includes a biaxial hinge structure 1, a first connection part 2 and a second connection part 3 hingedly connected by the biaxial hinge structure 1; the biaxial hinge structure 1 includes a hinge bracket 11 and at least two groups of rotating shafts arranged parallel to each other and rotatably connected to the hinge bracket 11, and the rotating shafts include a first rotating shaft 12 connected to the first connection part 2 and a second rotating shaft 13 connected to the second connection part 3.
[0037] like Figure 3 to Figure 4As shown, the hinge bracket 11 includes a cam structure 111, and the first connection part 2 and the second connection part 3 both have an articulated body. The articulated body is provided with a profiling groove 4 near the cam structure 111. The cam structure 111 can be accommodated in the profiling groove 4, and the profiling groove 4 provides sufficient rotation space for the cam structure 111 during the rotational folding and rotational unfolding of the first connection part 2 and the second connection part 3. Connecting ears 5 are formed on both sides of the profiling groove 4 at both ends of the articulated body, and the connecting ears 5 are provided with a connecting through hole 6 that is transmission-connected to the first rotating shaft 12 or the second rotating shaft 13. At the same time, the cam structure 111 is provided with a hinge through hole 7 coaxial with the connecting through hole 6, so that the first rotating shaft 12 or the second rotating shaft 13 can pass through.
[0038] The hinge through hole 7 is a hollow cylindrical through hole. The resistance, i.e., the torque, required by the biaxial hinge structure can be adjusted through the hollow cylindrical through hole 7 to meet various working force requirements.
[0039] In this embodiment, the hinge bracket 11 is a symmetrical structure, and two ends of the hinge bracket 11 have symmetrically arranged cam structures 111 .
[0040] like Figure 5 As shown, the structures of the first connection part 2 and the second connection part 3 can be the same or different. In the present embodiment, the first connection part 2 and the second connection part 3 have the same structure and both include a rotation limiting part 8 and a folding bonding part 9 which can respectively abut against each other after rotation. The rotation limiting part 8 and the folding bonding part 9 are connected by a preset rotation angle θ and are located at the connection to form a hinge angle Φ. The hinge bracket 11 is arranged at the connection between the rotation limiting part 8 and the folding bonding part 9.
[0041] The preset rotation angle θ is the angle at which the first connection portion 2 rotates relative to the second connection portion 3. For example, if the preset rotation angle θ is 120 degrees, then the hinge angle Φ is 120 degrees.
[0042] Taking the rotation angle θ of 120 degrees as an example, during the rotational folding process, by applying appropriate force to the first connection part 2 and the second connection part 3, after the first connection part 2 rotates 120 degrees relative to the second connection part 3, the folding and bonding parts 9 of the first connection part 2 and the second connection part 3 abut and fit each other, and the folding action is completed; during the rotational unfolding process, by applying force in opposite directions to the first connection part 2 and the second connection part 3, after the first connection part 2 rotates 120 degrees in the opposite direction relative to the second connection part 3, the rotation limiting parts 8 of the first connection part 2 and the second connection part 3 abut each other, that is, the first connection part 2 and the second connection part 3 are both limited and fixed, and the unfolding action is completed.
[0043] Furthermore, the folding and fitting portion 9 is transitionally connected to the rotation limiting portion 8 through the outer arc surface 10, so that the first connecting portion 2 and the second connecting portion 3 are smoother, more barrier-free and more labor-saving during the rotational folding and rotational unfolding process.
[0044] Further, such as Figure 6 The cam structure 111 includes a damping arc slope portion 1111 and a buffer arc slope portion 1112 which protrude outward and are smoothly connected to each other. The curvature radius of the damping arc slope portion 1111 is greater than the curvature radius of the buffer arc slope portion 1112, and the contoured groove 4 is located at the damping arc slope portion 1111 and has an inner arc surface 41 that fits the damping arc slope portion 1111, so that during the rotational folding and rotational unfolding of the first connecting portion 2 and the second connecting portion 3, the damping arc slope portion 1111 protruding outward has a damping effect on the first connecting portion 2 and the second connecting portion 3, that is, it has a certain buffering effect to achieve a slow and stable rotation process, and the force applied during manual operation is easier to control, which improves the safety of operation and provides a better experience.
[0045] In this embodiment, the hinge bracket 11 is provided with a plurality of groups, and the plurality of groups of hinge brackets 11 are evenly distributed on the hinged body, and the plurality of groups of hinge brackets 11 all have coaxial hinge through holes 7, and the first rotating axis 12 or the second rotating axis 13 is sequentially passed through the plurality of hinge through holes 7. By providing the plurality of groups of hinge brackets 11, the first connecting part 2 and the second connecting part 3 are subjected to more uniform force during relative rotational movement, and each working force value is easier to adjust.
[0046] In this embodiment, the connecting through hole 6 can be a polygonal hole, or a threaded hole.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
