[0053] Furthermore, if Figure 3-Figure 6 As shown, the shoulder support mechanism 2 includes a support body 21 and a connection component 22, wherein the bottom surface of the support body 21 overlaps the shoulder of the human body, the connection component 22 is connected between the support body 21 and the shell 1, and the connection component 22 can adjust the relative position of the support body 21 and the shell 1 along the direction in which the support body 21 and the shell 1 are close to or away from each other. By setting the connection component 22 to adjust the relative position of the support body 21 and the shell 1 along the direction in which the support body 21 and the shell 1 are close to or away from each other, the wireless power supply device can meet the use needs of people of different body shapes, thereby improving the application range of the wireless power supply device.

[0054] Alternatively, if Figure 3 As shown, in this embodiment, the support body 21 is a C-shaped arc structure, thereby forming a space for surrounding the human neck, and the end of the C-shaped arc structure is bent downward at a certain angle along the direction in which the support body 21 and the shell 1 approach or move away from each other, so as to facilitate overlapping with the human shoulder.

[0055] Further, in this embodiment, the material of the shoulder support mechanism 2 is plastic, for example, ABS engineering plastic, PET or PBT, etc., preferably ABS engineering plastic. Optionally, in other embodiments, the support body 21 can be made of a flexible material at the joint with the human shoulder, so as to better overlap the human shoulder and be more comfortable to wear.

The arrangement of the convex strip 223 and the groove 224 makes the height adjustment operation simple and smooth. Optionally, in this embodiment, a plurality of convex strips 223 are provided, and in other embodiments, the number of convex strips 223 can be set to one.

[0057] Optionally, in the present embodiment, a groove 224 is formed between two adjacent ridges 223 on the first connecting plate 221, and a ridge 223 is sandwiched between two adjacent grooves 224 on the second connecting plate 222. The ridge 223 on the first connecting plate 221 can be selectively snap-fitted and fixed with any one of the grooves 224 on the second connecting plate 222, and correspondingly, the ridge 223 on the second connecting plate 222 can be selectively snap-fitted and fixed with the groove 224 on the first connecting plate 221.

[0058] Optionally, in other embodiments, the second connecting plate 222 may be provided with at least one convex strip 223 along the direction in which the support body 21 and the shell 1 approach or move away from each other, and the first connecting plate 221 may be provided with a plurality of grooves 224 at intervals along the direction in which the support body 21 and the shell 1 approach or move away from each other.

[0059] Optionally, in this embodiment, the first connecting plate 221 and the second connecting plate 222 are both arc-shaped plates, and the second connecting plate 222 is an arc-shaped plate, which can be adapted to the shape of the support body 21 and is more beautiful. In other embodiments, the first connecting plate 221 can be fixedly connected to the shoulder support mechanism 2, and the second connecting plate 222 can be fixedly connected to the shell 1.

[0060] Furthermore, if Figure 3-Figure 6As shown, in order to ensure the stability and smoothness of the relative sliding adjustment of the shell 1 and the shoulder support mechanism 2 along the direction in which the support body 21 and the shell 1 approach or move away from each other, the connection assembly 22 also includes a guide member 226, a guide hole 225 is provided on the first connection plate 221, the guide hole 225 extends along the direction in which the support body 21 and the shell 1 approach or move away from each other, the guide member 226 is fixedly connected to the second connection plate 222, and the guide member 226 can move along the guide hole 225.

[0061] Optionally, the number of guide holes 225 can be set to multiple, and the multiple guide holes 225 are arranged at intervals in the horizontal direction, and each guide hole 225 is correspondingly provided with a guide member 226, so that the height sliding adjustment of the housing 1 relative to the shoulder support mechanism 2 is more stable. In this embodiment, two guide holes 225 are provided, and the number of guide holes 225 in other embodiments can be set according to needs.

[0062] Furthermore, if Figure 7 As shown, the connecting assembly 22 also includes two limit plates 227, and the two limit plates 227 are respectively connected to the two ends of the second connecting plate 222 at an angle, and the first connecting plate 221 is located between the two limit plates 227. The setting of the limit plates 227 can avoid circumferential displacement during the process of adjusting the height of the shell 1 and the shoulder support mechanism 2, thereby further improving the stability of the height adjustment.

[0063] In addition, if Figure 7 As shown, the connecting component 22 also includes a protective plate 228, which is an arc-shaped plate, and its two ends are connected to the limiting plate 227. The protective plate 228, the limiting plate 227 and the second connecting plate 222 form a restricted space, which can prevent the guide member 226 from falling when it is loose, thereby playing a protective role, and at the same time will not expose the internal structure of the connecting component 22.

[0064] Furthermore, if Figure 8As shown, the wireless power supply device also includes a rotating mechanism 4, which is configured to adjust the relative angle between the shell 1 and the shoulder support mechanism 2, so as to achieve the effect of meeting the needs of people of different body shapes. Specifically, the rotating mechanism 4 can be a damping hinge, one end of which is connected to the shoulder support mechanism 2, and the other end is connected to the shell 1. The damping hinge can increase the friction force when the shell 1 and the shoulder support mechanism 2 rotate relative to each other, and by precisely controlling the friction force in the rotation direction of the damping hinge, the shell 1 and the shoulder support mechanism 2 maintain the adjusted angle, so as to meet the use needs of people of different body shapes. Specifically, one end of the damping hinge is connected to the first connecting plate 221, and the other end is connected to the inside of the annular portion 11. In addition, the damping hinge is a prior art, and the working principle and specific structure of the damping hinge are not described here.

[0065] Furthermore, if Figure 8 As shown, the wireless power supply device also includes a neck support mechanism 3, which is arranged on the shoulder support mechanism 2. The neck support mechanism 3 is used to support the neck of the human body, providing another support point for the wireless power supply device, thereby further improving wearing comfort.

[0066] Specifically, Figure 8 As shown, the neck support mechanism 3 includes a support component 31 and a telescopic component 32. The support component 31 is connected to the inner side of the shoulder support mechanism 2 and is located in the middle part of the C-shaped arc structure. The support surface of the support component 31 that fits the human neck is adapted to the human neck. The first end of the telescopic component 32 is connected to the support component 31, and the second end of the telescopic component 32 is connected to the support body 21. The telescopic component 32 extends along the front and back direction of the human head, which improves the adaptability of the wireless power supply device to different human body structures, makes the wireless power supply device more comfortable to wear, and meets the usage needs of different human bodies.

[0067] Furthermore, the material of the support component 31 is not limited, such as plastic, silicone or rubber, or a secondary injection molding material of plastic and rubber / silicone. Preferably, the side of the support component 31 close to the human neck is made of rubber material, and the side away from the human neck is made of plastic material.

[0068] Specifically, Fig. 9As shown, the telescopic assembly 32 includes a telescopic part, a first support plate 326 and a second support plate 327, and the telescopic part includes a first section of a circular tube 323, a second section of a circular tube 324 and a third section of a circular tube 325 which are sequentially plugged in, wherein the diameters of the first section of the circular tube 323, the second section of the circular tube 324 and the third section of the circular tube 325 are sequentially increased, and the three sections of the circular tube can be pulled apart to form a long rod connected end to end, so that the telescopic assembly 32 can be adjusted along the front and rear directions of the human head, one end of the first section of the circular tube 323 is fixed to the support body 21 by being connected to the first support plate 326, and one end of the third section of the circular tube 325 is fixed to the support assembly 31 by being connected to the first support plate 326, and the setting of the telescopic assembly 32 is used to adjust the position of the support assembly 31 and the human neck, so as to meet the use requirements of different human bodies.

[0069] Optionally, the telescopic portion of the telescopic component 32 can be provided with multiple sections of circular tubes. In the present embodiment, the telescopic portion of the telescopic component 32 is provided with three sections of circular tubes. In other embodiments, the number of sections of circular tubes can be set according to requirements.

[0070] Specifically, Fig. 9 As shown, the outer surfaces of the first section of the circular tube 323, the second section of the circular tube 324 and the third section of the circular tube 325 are all recessed inwardly along the radial direction to form a guide groove 321. Correspondingly, the inner surfaces of the first section of the circular tube 323, the second section of the circular tube 324 and the third section of the circular tube 325 form corresponding protrusions. The guide groove 321 of the first section of the circular tube 323 is slidably matched with the protrusion formed on the inner surface of the second section of the circular tube 324, and the guide groove 321 of the second section of the circular tube 324 is slidably matched with the protrusion formed on the inner surface of the third section of the circular tube 325. By setting the guide groove 321, the telescopic component 32 maintains stability and smoothness when sliding and telescoping.

[0071] Furthermore, if Fig. 9As shown, the first section of the circular tube 323 and the second section of the circular tube 324 are both elastically connected with a clamping protrusion 322, and the second section of the circular tube 324 and the third section of the circular tube 325 are both provided with a clamping hole 328, and the clamping protrusion 322 on the first section of the circular tube 323 can be clamped into the clamping hole 328 on the second section of the circular tube 324, and the clamping protrusion 322 on the second section of the circular tube 324 can be clamped into the clamping hole 328 on the third section of the circular tube 325. The above arrangement prevents the second section of the circular tube 324 from coming off the first section of the circular tube 323, and also prevents the third section of the circular tube 325 from coming off the second section of the circular tube 324, thereby ensuring the reliability of the structure. Taking the extension and retraction of the second section of the circular tube 324 relative to the first section of the circular tube 323 as an example, in the original state where it is not extended, the clamping protrusion 322 abuts against the inner wall of the second section of the circular tube 324. When the second section of the circular tube 324 slides and extends to the limit position relative to the first section of the circular tube 323, the clamping protrusion 322 will encounter the clamping hole 328 on the second section of the circular tube 324 and be clamped in the clamping hole 328 on the second section of the circular tube 324, thereby achieving the limited fixation between the first section of the circular tube 323 and the second section of the circular tube 324. When the second section of the circular tube 324 slides and retracts relative to the first section of the circular tube 323, the clamping protrusion 322 is slightly pressed inwardly to retract the clamping protrusion 322, thereby making the second section of the circular tube 324 sleeved on the first section of the circular tube 323, so that the extension length of the second section of the circular tube 324 and the first section of the circular tube 323 can be adjusted, thereby improving the stability of the wireless power supply device. The adjustment process of the second section of the round tube 324 and the third section of the round tube 325 is the same as the above adjustment process, and will not be repeated here. Furthermore, the telescopic component 32 is made of metal material to ensure the structural strength when the telescopic component 32 reaches the maximum length. It should be noted that after the two adjacent sections of the round tube are adjusted to the corresponding positions, they can be locked and fixed by bolts. Since the specific structure of the bolts for locking and fixing belongs to the prior art, it will not be repeated.

[0072] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
