[0032] A bracket is used to support a mobile phone or a tablet computer, etc. For the convenience of description, only the support of the mobile phone will be described hereinafter. The bracket includes a housing 1, a suction cup 2, a vacuum pump 3, a first circuit board 4, a turntable 5, a second circuit board 6 and a wireless charging coil 7. In some embodiments, the housing 1 is in the shape of a hollow cylinder, and of course, it can also be in other shapes, such as a polygon. The hollow part of the housing 1 forms a first accommodation cavity 101. The housing 1 has a first end 102 and a second end 103. In some embodiments, the housing 1 includes an upper housing 104 and a lower housing 105. The first end 102 is located at the lower housing 105, and the second end 103 is located at the upper housing 104. The upper housing 104 and the lower housing 105 are fixedly connected to form the first accommodation cavity 101. The design of the upper housing 104 and the lower housing 105 facilitates the arrangement of other components in the first accommodation cavity 101, such as the vacuum pump 3 and the first circuit board 4, etc. The suction cup 2 is provided at the first end 102. The suction cup 2 can adsorb on a desktop or a wall surface, etc., to fix the bracket on the wall or the desktop. The vacuum pump 3 is provided in the first accommodation cavity 101. The air extraction port of the vacuum pump 3 is communicated with the suction cup 2. When the suction cup 2 adsorbs on the wall or the desktop, the vacuum pump 3 can extract the air in the suction cup 2 to form a vacuum in the suction cup 2, so that the suction cup 2 stably adsorbs on the wall or the desktop. The first circuit board 4 is provided in the first accommodation cavity 101. The first circuit board 4 is electrically connected to the vacuum pump 3. The turntable 5 is provided at the second end 103. The turntable 5 is rotatably connected to the housing 1. The wireless charging coil 7 is used to charge the mobile phone.

The second circuit board 6 is provided with a first annular conductive track 601 and a second annular conductive track 602. The positive conductive head 401 abuts against the first annular conductive track 601, and the negative conductive head 402 abuts against the second annular conductive track 602. When it is necessary to adjust the viewing angle of the mobile phone, rotate the turntable 5. Since the turntable 5 is fixedly connected to the second circuit board 6 and the wireless charging coil 7, the rotation of the turntable 5 drives the second circuit board 6 and the wireless charging coil 7 to rotate together. The positive conductive head 401 slides on the first annular conductive track 601, and the negative conductive head 402 slides on the second annular conductive track 602, so that during the rotation of the turntable 5, the first circuit board 4 and the second circuit board 6 remain electrically connected.In this application, the design is adopted that the positive electrode conducting head 401 slides on the first annular conducting track 601, and the negative electrode conducting head 402 slides on the second annular conducting track 602. When the turntable 5 rotates relative to the housing 1 to adjust the viewing angle of the mobile phone, there is no situation where the bracket cannot be used due to the twisting and damage of the wire connecting the first circuit board 4 and the second circuit board 6, greatly extending the service life of the bracket. In some embodiments, the positive electrode conducting head 401 and the negative electrode conducting head 402 are made of PIN pins.

[0033] In some embodiments, a plurality of the positive electrode conducting heads 401 and the negative electrode conducting heads 402 are circumferentially arranged. On the one hand, when a certain positive electrode conducting head 401 or negative electrode conducting head 402 is damaged, since there are other good positive electrode conducting heads 401 or negative electrode conducting heads 402, the first circuit board 4 and the second circuit board 6 can still maintain electrical connection; on the other hand, compared with a group of positive electrode conducting heads 401 and negative electrode conducting heads 402, multiple groups of positive electrode conducting heads 401 and negative electrode conducting heads 402 can reduce the heat generation of the positive electrode conducting heads 401 and the negative electrode conducting heads 402 and extend the service life of the positive electrode conducting heads 401 and the negative electrode conducting heads 402.

[0034] In some embodiments, the second end 103 has a rotating shaft portion 106. The rotating shaft portion 106 is cylindrical. The turntable 5 is provided with a first through hole 501.

[0035] In some embodiments, the second circuit board 6 is disposed between the housing 1 and the turntable 5, that is, the second circuit board 6 is disposed on a surface of the turntable 5 close to the first end 102. The housing 1 is provided with a third through hole. The positive electrode conducting head 401 and the negative electrode conducting head 402 pass through the third through hole and abut against the second circuit board 6. In some embodiments, the second circuit board 6 is also fixedly connected to the turntable 5 by screws. In some embodiments, the second circuit board 6 is also adhered to the turntable 5 with glue.

During the rotation of the turntable 5 relative to the shell 1, the spring 9 expands and contracts, thereby pushing the steel ball 10 to hit the fixed disk 8, thereby generating sound feedback. In some embodiments, the surface of the fixed disk 8 in contact with the steel ball 10 is provided with a plurality of grooves, and when the turntable 5 rotates relative to the shell 1, the steel ball 10 is transferred from one groove to another groove, thereby generating a sense of stuck. In some embodiments, the fixed plate 8 is disposed between the wireless charging coil 7 and the rotating plate 5, and the bottom of the second receiving groove is higher than the fixed plate 8, that is, the bottom of the wireless charging coil 7 is higher than the fixed plate 8, and there is a gap between the bottom of the wireless charging coil 7 and the fixed plate 8. When the wireless charging coil 7 rotates following the rotating plate 5, the wireless charging coil 7 and the fixed plate 8 do not rub due to contact.

[0039] In some embodiments, a columnar fixing portion 107 is provided on the rotating shaft portion 106, and the fixing portion 107 is non-cylindrical. The fixing disk 8 is provided with a second through hole 801, and the second through hole 801 is connected to the fixing portion 107, so as to realize the connection between the fixing disk 8 and the housing 1. Because the fixing portion 107 is non-cylindrical, when the rotating disk 5 rotates relative to the housing 1, the fixing disk 8 does not rotate relative to the housing 1. In some embodiments, the fixing portion 107 is a quadrangular prism, and the second through hole 801 is a square hole adapted to the quadrangular prism.

[0040] In some embodiments, the fixed disk 8 includes a cover plate portion 802 and an annular portion 803 extending towards the first end 102.

[0041] The bracket further includes an ambient light 11. The second end 103 is provided with a fifth through hole, and the ambient light 11 is embedded in the fifth through hole, and the ambient light 11 is disposed around the rotating disk 5. The setting of the ambient light 11 can, on the one hand, increase the beauty of the bracket, and on the other hand, the bracket can also be used as a night light at night. In some embodiments, the ambient light 11 is electrically connected to the first circuit board 4.

[0042] In some embodiments, the bracket further includes a starting mechanism for starting the vacuum pump 3. In some embodiments, the starting mechanism includes a starting member 12.

In some embodiments, the bracket further includes a releasing mechanism 13. When it is desired to remove the suction cup 2 from the mobile phone or the wall surface, the releasing mechanism 13 is operated, and the releasing mechanism 13 introduces air into the suction cup 2, thereby balancing the pressure between the suction cup 2 and the outside. In some embodiments, the releasing mechanism 13 includes a push switch. When the push switch is pressed, the push switch introduces air into the suction cup 2, thereby balancing the pressure between the suction cup 2 and the outside.
