[0034] [First embodiment]

[0035] See also Figures 1-3 An embodiment of the present invention provides a rotating shaft structure 10 , which includes, for example: a first straight segment 11 , a curved segment 12 and a second straight segment 13 .

[0036] Specifically, the two ends of the curved segment 12 are connected to the second straight segment 13 and the first straight segment 11 respectively. Figure 2 As shown, the curved segment forms an angle a1 between the first straight segment 11 and the second straight segment 13 .

[0037] Among them, the hinge structure 10 of this embodiment can be applied to a bracket structure, and the bracket structure can be connected to the back of an electronic device, such as a mobile phone, a power bank, a laptop computer, etc. The hinge structure 10 is, for example, a connecting rod structure, and the first straight segment 11 and the second straight segment 13 can be, for example, two structural parts of straight segments on the connecting rod structure. The first straight segment 11 and the second straight segment 13 are connected by a curved segment 12, which can also be understood as a part of the hinge structure bending upward, so that a certain inclination angle is formed between the first straight segment 11 and the second straight segment 13. Since the hinge structures in the prior art are all horizontal or straight connecting rod structures, and this connecting rod structure, when used as a rotating part in the bracket structure, makes it easy for the part where the connecting rod structure is connected to the bracket to be stressed when the connecting structure rotates, causing the connecting part to be easily broken. The present application sets a curved segment 12 to be connected to the first straight segment 11 and the second straight segment 13 respectively, so that the curved segment 12 can form an angle a1 between the first straight segment 11 and the second straight segment 13, so that the first straight segment 11 and the second straight segment 13 can be connected obliquely. The shaft structure 10 formed by this structure can distribute the force exerted on the shaft structure 10 during rotation to the first straight segment 11 and the second straight segment 13, thereby improving the overall force strength of the shaft structure 10, preventing the shaft structure 10 from being easily damaged during rotation, and improving the service life of the shaft structure 10.

[0038] In a preferred embodiment of this embodiment, if Figure 2 As shown, the bending angle a2 of the curved section 12 is greater than 90 degrees and less than 180 degrees; and / or the included angle a1 is greater than 90 degrees and less than 180 degrees. By limiting the bending angle a2 of the curved section and / or the included angle a1 to an obtuse angle, the hinge structure 10 can better fit the annular bracket, facilitating the bracket's rotation relative to the back of the electronic device.

[0039] Further, the curved section 12 is in an arc shape, the curved angle a2 of the curved section 12 is 152.5-160 degrees, and the length of the curved section 12 is 5-8 mm. The length of the curved section 12 is the length after the curved section 12 is straightened. By limiting the curved angle a2 of the curved section 12 and the length of the curved section, when the first straight section 11 is arranged in the support, the first straight section 11 can be prevented from being unable to rotate in the support.

[0040] Further, as shown in Fig. 1, the curved section 12 is in an arc shape, the curved angle a2 of the curved section 12 is 152.5-160 degrees, and the length of the curved section 12 is 5-8 mm. The length of the curved section 12 is the length after the curved section 12 is straightened. By limiting the curved angle a2 of the curved section 12 and the length of the curved section, when the first straight section 11 is arranged in the support, the first straight section 11 can be prevented from being unable to rotate in the support. Figure 1As shown, the first straight section 11 is provided with a first plane 111, the first plane 111 is arranged along the length direction of the first straight section 11 and extends from one end of the first straight section 11 to the other end; the curved section 12 is provided with a second plane 121, the second plane 121 is coplanar with the first plane 111; the second straight section 13 is provided with a third plane 131, the third plane 131 is arranged along the length direction of the second straight section 13 and extends from one end of the second straight section 13 to the other end, and the third plane 131 is parallel to the first plane 111. The first plane 111 can be formed by flattening a portion on the top of the first straight section 11, the second plane 121 can be formed by flattening a portion on the top of the curved section 12, and the first plane 111 and the second plane 121 can be flattened at the same time, that is, the first plane 111 and the second plane 121 are in the same plane. The third plane 131 can be formed by flattening a portion on the top of the second straight section 13. By arranging the first plane 111, the second plane 121 and the third plane 131 on the first straight section 11, the curved section 12 and the second straight section 13 respectively, the rotating shaft structure 10 can be conveniently assembled in the support, and the third plane 131 can cooperate with the hinge part in the support to generate a certain torsional resistance in the hinge part during rotation, thereby forming a certain damping force, which can realize support at any angle. The hinge part can be a curled portion, one end of which is fixedly connected with a connecting portion on the support, and the other end is curled and fixedly connected with the one end of the curled portion or the connecting portion and forms a shaft hole. The second straight section 13 of the rotating shaft structure 10 can be inserted into the shaft hole and rotated in the shaft hole. In other embodiments, the other end of the first straight section 11 opposite to the first plane 111 can also be provided with a plane portion, that is, the opposite two surfaces of the first straight section 11 are provided with planes, which can further facilitate the assembly of the first straight section 11 in the annular groove of the support. Of course, the planes on the first straight section 11 can be arranged according to actual conditions, which are not limited herein. At the same time, the curved section 12 and the second straight section 13 can also be provided with plane portions on both surfaces. By arranging the planes on both surfaces, the rotating shaft structure 10 can be conveniently assembled, and the second straight section 13 can be conveniently assembled in the curled portion of the support.

[0041] Specifically, as Figure 3As shown, the height of the second plane 121 is lower than the height of the third plane 131, and a step position 15 is formed between the second plane 121 and the third plane 131. When the height of the second plane 121 is lower than the height of the third plane 131, the step position 15 can be formed at the top of the second straight section 13 and the curved section 12. By forming the step position 15, the shaft structure 10 can be conveniently stressed at the step position 15, and the shaft structure 10 can be conveniently assembled in the support. The support can be provided with mounting holes and grooves, the first straight section 11 and the curved section 12 are inserted into the grooves through the mounting holes, and the second straight section 13 is clamped in the mounting hole at the end close to the curved section 12 through the step position 15. Thus, the shaft structure 10 can be conveniently clamped and assembled in the support.

[0042] Further, as shown, Figures 1-3 The shaft structure 10 further includes a third straight section 14 provided at the end of the second straight section 13 away from the curved section 12. The third straight section 14 can be another straight section of the shaft structure 10. By connecting the third straight section 14 with the second straight section 13, the stress on the entire shaft structure 10 can be more balanced, and the shaft structure 10 is less likely to break during rotation.

[0043] Further, the third straight section 14 is provided with a fourth plane 141, which is coplanar with or parallel to the first plane 111. The height of the fourth plane 141 is lower than the height of the third plane 131. By setting the height of the fourth plane 141 lower than the height of the third plane 131, i.e., the top of the second straight section 13 is higher than the top of the third straight section 14, the third straight section 14 of the shaft structure 10 can be conveniently assembled in the support, i.e., the first straight section 11 and the curved section 12 can be assembled on the left side of the support, the third straight section 14 can be assembled on the right side of the support, and the second straight section 13 can be inserted into the rounded portion of the support, so that the support can be conveniently assembled, rotated, and supported at any angle.

[0044] Further, as shown, Figure 3 The shaft structure 10 can be provided with an inclined surface 16. Since the height of the fourth plane 141 is lower than the height of the third plane 131, a step position 15 can be formed at the connection between the third plane 131 and the fourth plane 141. The inclined surface 16 is connected between the third plane 131 and the fourth plane 141, one end of the inclined surface 16 is connected to the end of the third plane 131 close to the fourth plane 141, and the other end of the inclined surface 16 is connected to the end of the fourth plane 141 close to the third plane 131. Figure 3, one end of the inclined surface 16 is connected with the right end of the third plane 131, the other end of the inclined surface 16 is connected with the left end of the fourth plane 141, and the inclined surface 16 is inclined from the one end of the third straight line segment 14 close to the second straight line segment 13 to the second straight line segment 13, that is, the inclined surface is inclined downward from the right end of the third straight line segment 14 to the left end of the second straight line segment 13. By arranging the inclined surface 16 to be connected between the third plane 131 and the fourth plane 141, the strength of the connection between the second straight line segment 13 and the third straight line segment 14 can be improved, so that the connection is not prone to breaking, and the service life of the rotating shaft structure 10 is improved.

[0045] Further, the fourth plane 141 includes two, and the two fourth planes 141 are symmetrically arranged on the third straight line segment 14. By arranging two fourth planes 141 symmetrically on both sides, the stress strength of the third straight line segment 14 can be further improved, thereby improving the service life of the rotating shaft structure 10.

[0046]

Second embodiment

[0047] Reference Figures 4-7 The utility model embodiment provides a support structure 1, for example, it includes: support piece 20, connecting piece 30 and rotating shaft structure 10.

[0048] The connecting piece 30 is rotationally connected with the support piece 20. The rotating shaft structure 10 is connected with the connecting piece 30 and rotationally connected with the support piece 20. The rotating shaft structure 10 is the rotating shaft structure described in the first embodiment, and the specific structure of the rotating shaft structure 10 can refer to the part described in the first embodiment, and details will not be repeated here. The support piece 20 is for example a support structure, which can be for example a ring-shaped support, which is used to support electronic devices, such as mobile phones, notebook computers, power banks, etc. The connecting piece 30 is for example a structure for connecting the support structure of the prior art with the electronic device, which is for example a ring-shaped connecting piece corresponding to the ring-shaped support, and the connecting piece 30 has the function of accommodating the ring-shaped support. The support structure 1 can be connected to the back of the electronic device or the back of the electronic device protective shell.

[0049] The connecting piece 30 is provided with a mounting portion 40, the rotating shaft structure 10 is fixedly mounted in the mounting portion 40, and the second straight section 13 of the rotating shaft structure 10 is rotationally connected with the support piece 20. In this embodiment, the mounting portion 40 is used to mount a mounting structure for clamping the rotating shaft structure 10. The mounting structure may, for example, include a groove portion for placing the first straight section 11 and the curved section 12, and a through hole portion for placing the second straight section. The mounting structure may be arranged according to the specific structure of the rotating shaft structure 10. The mounting portion may, for example, be arranged on the end portion, for example, the lower end portion, of the annular connecting piece. The mounting portion 40 may, for example, be arranged on the lower end portion of the connecting piece 30, and be a groove structure for placing the rotating shaft structure 10. The groove structure may, for example, be provided with a groove portion corresponding in size to the rotating shaft structure 10, and the groove portion may be used to mount the rotating shaft structure 10.

[0050] Since the rotating shaft structure in the prior art is a horizontal or straight connecting rod structure, when the connecting rod structure is used as a rotating portion in a support structure, the connecting structure is prone to being subjected to stress at the portion where the connecting rod structure is connected with the support piece, which causes the connecting portion to be prone to breaking. According to the present application, the curved section 12 is connected with the first straight section 11 and the second straight section 13, respectively, so that the curved section 12 forms an included angle a1 between the first straight section 11 and the second straight section 13, thereby enabling the first straight section 11 and the second straight section 13 to be connected at an inclination. The rotating shaft structure 10 formed by this structure can distribute the force acting on the rotating shaft structure 10 when the rotating shaft structure 10 is rotating to the first straight section 11 and the second straight section 13, thereby improving the overall stress strength of the rotating shaft structure 10. When the rotating shaft structure 10 is mounted on the connecting piece 30 and rotationally connected with the support piece 20, and the support piece 20 needs to be opened for support, the support piece 20 is rotated relative to the rotating shaft structure 10, so that the force acting during rotation is distributed by the first straight section 11, the curved section 12 and the second straight section 13 of the rotating shaft structure 10. This prevents the rotating shaft structure 10 from being easily damaged when the support piece 20 is rotated, improves the service life of the rotating shaft structure 10, and thereby improves the service life of the entire support structure 1.

[0051] Further, as shown in FIG. 1, the support structure 1 may, for example, include a plurality of support pieces 20, and the plurality of support pieces 20 may, for example, be arranged in parallel with each other. Figures 4-6As shown, the support piece 20 is provided with a roll part 21, the roll part 21 is sleeved on the second straight section 13, and the roll part 21 is rotationally connected with the second straight section 13. One end of the roll part 21 is fixedly connected with the end of the connecting piece 30, the other end of the roll part 21 is fixedly connected with the end of the connecting piece 30 after being curled, and an axle hole is formed, the second straight section 13 of the rotating shaft structure 10 can be inserted into the axle hole and rotate in the axle hole. Wherein, the second straight section 13 is provided with a third plane 131, the third plane 131 can be used for the support piece 20 to rotate relative to the rotating shaft structure 10, because the second straight section 13 is inserted into the axle hole of the roll part 21, at this time, the edge of the third plane 131 can be in contact with the inner wall of the axle hole of the roll part 21, so that a torsional resistance is generated to the support piece 20, so that the support piece 20 can be rotated to any angle through the resistance, and the resistance of any angle is realized through the cooperation of the third plane 131 and the roll part 21, so that the arbitrary angle supporting function of the support piece 20 is realized.

[0052] Further, as shown, Figures 5-7 As shown, the mounting portion 40 can for example include a first mounting hole 41, a groove 42 and a second mounting hole 43, the first straight section 11 of the rotating shaft structure 10 and the curved section 12 of the rotating shaft structure 10 are clamped in the groove 42, one end of the second straight section 13 close to the curved section 12 is inserted into the first mounting hole 41, the rotating shaft structure 10 further includes a third straight section 14, the third straight section 14 is inserted into the second mounting hole 43. The groove 42 can for example be a groove on the left side of the lower end of the connecting piece 30, the first mounting hole 41 can be located on the left side of the lower end of the connecting piece 30, the first mounting hole 41 can be in communication with the groove 42, the first straight section 11 and the curved section 12 can pass through the first mounting hole 41 and be clamped in the groove 42, the third straight section of the rotating shaft structure 10 can be inserted into the second mounting hole 43, the curved section 12 is assembled in the groove 42 to realize the gap assembly between the rotating shaft structure 10 and the connecting piece 30, so that the stress area of the rotating shaft structure 10 can be increased. The first straight section 11 of the rotating shaft structure 10 is installed in the groove 42 and cannot be loosened. The third straight section 14 can be tightly assembled in the connecting piece 30 to realize clamping, and at the same time, the second straight section 13 of the rotating shaft structure 10 cannot be loosened.

[0053] Further, the connecting piece 30 is circular or disc-shaped structure, the groove 42 is arranged on the side wall of the connecting piece 30 and extends along the circumference of the connecting piece 30, and the groove 42 is communicated with the first mounting hole 41. By arranging the groove 42 on the side wall of the connecting piece 30 and extending along the circumference of the connecting piece 30, the groove 42 can be matched with the first straight section 11 and the curved section 12, and the step position 15 can be formed by the height difference between the second plane 121 on the curved section 12 and the third plane 131 on the second straight section 13 of the rotating shaft structure 10, so that the first straight section 11 and the curved section 12 can be installed into the groove 42 through the first mounting hole 41, and the second straight section 13 can be clamped outside the first mounting hole 41. Further, the first straight section 11 and the curved section 12 can be hidden in the side wall of the connecting piece 30, so that the pushing and pulling force of the support piece 20 can be enhanced, and the stress of the connecting piece 30 after the rotating of the support piece 20 can be relieved, thereby reducing the deformation of the part connected with the rotating shaft structure 10.
