[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] like Figures 1 to 4 As shown, a connecting shaft with rotation limit described in one embodiment of the utility model includes a first annular connector 1 connected to the first module 5 and a second annular connector 2 connected to the second module 6, the first module 5 and the second module 6 are in close contact with each other on one side, the second annular connector 2 is sleeved on the outside of the first annular connector 1, the through hole on the first annular connector 1 is used for wiring, and a limiting mechanism 3 is arranged between the first annular connector 1 and the second annular connector 2, and the limiting mechanism 3 is used to limit the rotation angle of the second annular connector 2 around the first annular connector 1.

[0029] During installation, first connect the first annular connector 1 to the first module 5, connect the second annular connector 2 to the second module 6, then dock the first module 5 and the second module 6, and ensure that the two connected sides are close to each other. At this time, the second annular connector 2 is sleeved on the first annular connector 1, and the second annular connector 2 can rotate relative to the first annular connector 1. The through hole on the first annular connector 1 is used for wiring, which is convenient for connecting the first module 5 and the second module 6 through wires to ensure smooth transmission of power or signals. The second annular connector 2 can rotate relative to the first annular connector 1, so as to adjust the relative position between the first module 5 and the second module 6. During the position adjustment process, the limit mechanism 3 between the first annular connector 1 and the second annular connector 2 will ensure that the rotation angle is within a predetermined range. Once the set angle is reached, the limit mechanism 3 will automatically prevent further rotation to ensure the stability and safety of the connecting shaft.

[0030] In this embodiment, the first module 5 and the second module 6 are tightly connected by the first annular connector 1 and the second annular connector 2, so that the first annular connector 1 and the second annular connector 2 are hidden in the first module 5 and the second module 6, so that the connecting shaft is not easy to be damaged, and dust and dirt are not easy to accumulate, and the whole mechanism is more beautiful. Secondly, since the first annular connector 1 is provided with a through hole, the cables can pass through in an orderly manner, avoiding the problem of cable confusion and damage, and improving the convenience and safety of use. Finally, by setting a limit mechanism 3 to control the rotation angle of the first annular connector 1 and the second annular connector 2, damage caused by excessive rotation is prevented, the service life of the equipment is guaranteed, and excessive rotation is prevented from causing the cables in the through hole to be repeatedly wound and damaged.

[0031] like Figures 1 to 3 As shown, in a preferred embodiment, the first and second limiting rings 101 and 102 are respectively provided on the two end surfaces of the first annular connector 1, the inner diameter of the first limiting ring 101 and the inner diameter of the second limiting ring 102 are equal to the inner diameter of the first annular connector 1, and the outer diameter of the first limiting ring 101 and the outer diameter of the second limiting ring 102 are larger than the inner diameter of the second annular connector 2.

[0032] When the second annular connector 2 is sleeved on the first annular connector 1, since the first two end surfaces of the first annular connector 1 are respectively provided with the first limiting ring 101 and the second limiting ring 102, and the outer diameters of the first limiting ring 101 and the second limiting ring 102 are larger than the inner diameter of the second annular connector 2, the axial movement of the second annular connector 2 is blocked by the two limiting rings. At this time, the second annular connector 2 is stably restricted on the first annular connector 1, thereby effectively preventing the second annular connector 2 from falling off the first annular connector 1.

[0033] In this embodiment, by setting the first limiting ring 101 and the second limiting ring 102 on the two end surfaces of the first annular connector 1, the outer diameters of the first limiting ring 101 and the second limiting ring 102 are larger than the inner diameter of the second annular connector 2, which effectively prevents the second annular connector 2 from accidentally falling off from the first annular connector 1, enhances the connection stability between the first module 5 and the second module 6, and ensures the safety and reliability of the entire connection system.

[0034] like Figure 2 As shown, in a preferred embodiment, the second limiting ring 102 is detachably connected to the first annular connector 1. Specifically, the second limiting ring 102 is connected to the first annular connector 1 by screws. A positioning column 103 is provided on the first annular connector 1, and a positioning hole 104 cooperating with the positioning column 103 is provided on the second limiting ring 102.

[0035] During installation, first put the second annular connector 2 on the first annular connector 1, then place the second limiting ring 102 on the first annular connector 1, align the positioning hole 104 on the second limiting ring 102 with the positioning column 103 on the first annular connector 1, and tighten the screws to firmly connect the second limiting ring 102 to the first annular connector 1, thereby limiting the axial movement of the second annular connector 2.

[0036] In this embodiment, by making the second limiting ring 102 detachably connected to the first annular connector 1, and equipping the positioning column 103 and the positioning hole 104 for precise alignment, it is convenient to sleeve the second annular connector 2 onto the first annular connector 1, thereby improving the flexibility and convenience of the installation process. In addition, by using the positioning column 103 and the positioning hole 104 in coordination, it is possible to ensure that the connection between the second limiting ring 102 and the first annular connector 1 is more stable and reliable, effectively preventing equipment failures and safety hazards caused by unstable connections, and improving work efficiency.

[0037] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the first limiting ring 101 and the second limiting ring 102 are respectively provided with a first wiring channel 105 and a second wiring channel 106 along the radial direction, the first wiring channel 105 runs through the inner and outer sides of the first limiting ring 101, and the second wiring channel 106 runs through the inner and outer sides of the second limiting ring 102.

[0038] During the assembly process, when the second annular connector 2 is sleeved onto the first annular connector 1 and is limited by the first limiting ring 101 and the second limiting ring 102, the user can start to arrange the cables as needed. First, the user can connect the first end of the cable to the device in the first module 5, and the second end passes through the first wiring channel 105 of the first limiting ring 101, and the cable smoothly passes into the through hole of the first annular connector 1. Then, it passes through the second wiring channel 106 of the second limiting ring 102, and finally connects to the device in the second module 6. The cables are neatly arranged between the first annular connector 1 and the second annular connector 2, and the cables are loosely connected between the first module 5 and the second module to prevent them from being torn off during the rotation process.

[0039] By respectively providing the first routing channel 105 and the second routing channel 106 on the first limiting ring 101 and the second limiting ring 102, the efficiency and safety of cable routing are improved. The cables can pass through the routing channels in an orderly manner, avoiding the confusion and potential safety hazards that may be caused by arranging the cables randomly inside the connector. At the same time, since the cables are arranged neatly and orderly, subsequent maintenance and repair work is also facilitated, thereby improving the reliability and maintainability of the entire system.

[0040] like Figures 1 to 4As shown, in a preferred embodiment, the limiting mechanism 3 includes a limiting groove 301 arranged on the outer edge of the first annular connecting member 1 and a limiting block 302 arranged on the inner wall of the second annular connecting member 2, the limiting block 302 is slidably connected to the limiting groove 301, and the length of the limiting groove 301 is the stroke of the limiting block 302.

[0041] When in use, the second annular connector 2 rotates relative to the first annular connector 1, and the limit block 302 arranged on the inner wall of the second annular connector 2 slides in the limit groove 301 on the outer edge of the first annular connector 1. As the rotation continues, the limit block 302 will slide along the trajectory of the limit groove 301. The stroke of the limit block 302 is controlled by the length of the limit groove 301. When the limit block 302 slides to one end of the limit groove 301, the second annular connector 2 reaches an extreme position; when the limit block 302 slides to the other end of the limit groove 301, the second annular connector 2 reaches another extreme position, thereby limiting the rotation angle of the first module 5 and the second module 6. In this embodiment, the center angle of the limit groove 301 is 90°, that is, the relative rotation range of the first module 5 and the second module 6 is 90°. In practical application, the center angle of the limit groove 301 can be set as needed.

[0042] In this embodiment, the relative rotation angle between the first annular connector 1 and the second annular connector 2 is precisely controlled by the cooperation of the limiting groove 301 and the limiting block 302, which not only improves the operation accuracy of the device, but also ensures the stability and safety of the device during the rotation process. At the same time, by adjusting the center angle of the limiting groove 301, the rotation angle range can be flexibly changed according to different usage requirements, so that the limiting mechanism 3 has a wide range of applicability.

[0043] like Figures 2 to 4 As shown, in a preferred embodiment, limiting grooves 303 are respectively provided at both ends of the limiting groove 301 , and limiting protrusions 304 are provided on the limiting block 302 , and the limiting protrusions 304 can be engaged with the limiting grooves 303 .

[0044] When in use, as the second annular connector 2 rotates relative to the first annular connector 1, the limit block 302 slides in the limit slot 301. When the second annular connector 2 rotates to the limit position, the limit protrusion 304 on the limit block 302 will just engage with the limit groove 303 at the end of the limit slot 301. During the engagement process, due to the close fit between the structures, the interaction between the mechanical structures will produce a crisp sound, which is used to give clear feedback to the user, prompting the user that the limit position of rotation has been reached.

[0045] In this embodiment, by setting the engaging limit protrusion 304 and the limit groove 303, the first module 5 and the second module 6 are effectively prevented from exceeding the preset rotation range. The crisp sound generated when engaging is also provided to provide the user with intuitive and immediate feedback, thereby enhancing the operational safety of the equipment and improving the user experience, so that the user can more accurately perceive and control the rotation angle during use, thereby improving work efficiency and operation accuracy.

[0046] like Figures 2 to 4 As shown, in a preferred embodiment, a rotation feedback mechanism 4 is provided between the first annular connector 1 and the second annular connector 2, and the rotation feedback mechanism 4 is used to make a sound when the first annular connector 1 and the second annular connector 2 rotate relative to each other.

[0047] The rotation feedback mechanism 4 includes a corrugated groove 401 disposed on the outer edge of the first annular connecting member 1 and a telescopic member 402 disposed on the second annular connecting member 2, an elastic member 403 is disposed between the telescopic member 402 and the second annular connecting member 2, and the telescopic member 402 can make a sound when sliding in the corrugated groove 401. The corrugated groove 401 and the limiting groove 301 have the same central angle.

[0048] The groove depths of the middle section of the corrugated groove 401 are the same, and the depths of the grooves at both ends are greater than the depth of the grooves in the middle section.

[0049] When in use, when the first annular connector 1 and the second annular connector 2 begin to rotate relative to each other, the telescopic member 402 disposed on the second annular connector 2 will slide in the corrugated groove 401 on the outer edge of the first annular connector 1. Since the groove depths in the middle section of the corrugated groove 401 are the same and the groove depths at both ends are larger, when the telescopic member 402 slides to the middle section of the corrugated groove 401, the sliding process is relatively smooth and the sound is uniform due to the consistent groove depths, providing real-time feedback for the rotation process. However, when the telescopic member 402 slides to both ends of the corrugated groove 401, due to the sudden increase in the groove depth, the telescopic member 402 will collide with the bottom of the groove under the action of the elastic member 403, thereby generating an obvious sound, prompting the user that the rotation limit position has been reached.

[0050] In this embodiment, by setting the rotation feedback mechanism 4, the rotation feedback mechanism 4 realizes real-time sound feedback during the rotation process under the action of the corrugated groove 401 and the telescopic member 402, enhances the intuitiveness of the user's operation, enables the user to more accurately perceive the progress and position of the rotation, and provides the user with a clear indication of whether the rotation has reached the limit position through the change of the sound. In addition, since the elastic member 403 is used to drive the telescopic member 402 to maintain contact with the corrugated groove 401, the reliability and durability of the rotation feedback mechanism 4 are guaranteed, and it can meet the needs of long-term and frequent use.

[0051] like Figures 4 to 6As shown, a wireless power supply device in one embodiment of the utility model comprises the above-mentioned connecting shaft with rotation limit, the first module 5 and the second module 6, and the first module 5 and the second module 6 are both provided with wireless charging positions. The first annular connecting member 1 can be integrally formed with the housing of the first module 5, or connected by buckles, fasteners, etc., and the second annular connecting member 2 and the second module 6 are also the same.

[0052] When using the wireless power supply device, first rotate the second module 6 to make it rotate relative to the first module 5, adjust the relative positions of the first module 5 and the second module 6, so that the second module 6 is partially offset from the first module 5 to unfold the wireless charging position on the second module 6. After fully unfolded, the user places the devices that need to be charged on the wireless charging positions of the first module 5 and the second module 6 respectively.

[0053] In this embodiment, by setting the connecting shaft, the user can adjust the relative position of the first module 5 and the second module 6 according to actual needs to expand the wireless charging position, thereby powering multiple devices. At the same time, by setting the limit mechanism 3, the device damage caused by excessive rotation is effectively prevented, bringing a more comfortable and convenient charging experience to the user.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
