Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging devices, and in particular to an easily peelable adsorption-type wireless charging device. Background Art

[0002] Wireless charging devices have been widely accepted and recognized due to their convenience and speed. The principle of wireless charging is electromagnetic induction. Energy is transmitted between the wireless charging device and the electronic device to be charged via a magnetic field. No wire connection is required between the wireless charging device and the electronic device to be charged. It is highly intelligent and has been widely used in various fields such as smartphones and tablets, automobiles, homes and offices, and medical care.

[0003] Adsorption-type wireless charging devices are usually fixed to a fixed surface via a suction cup at the bottom. By pressing the suction cup on the fixed surface, the air inside the suction cup is squeezed out, forming a certain vacuum state. Under the action of the internal and external pressure difference, the edge of the suction cup is firmly adsorbed on the fixed surface. When removing the adsorption-type wireless charging device from the fixed surface, it is usually directly unplugged. Due to the strong suction force of the suction cup, removal is laborious and inconvenient. Utility Model Content

[0008] Furthermore, the through hole is a tapered structure that is larger on the outside and smaller on the inside, and the end of the sealing piece facing the blind hole column is a tapered plug corresponding to the tapered structure. When the release switch is pressed, the tapered plug translates in a direction away from the tapered structure, and a gap appears between the sealing piece and the through hole.

[0009] Furthermore, the blocking member and the suction cup are both flexible silicone bodies, the suction cup includes a suction cup seat and an arc-shaped suction cup edge integrally formed with the suction cup seat, and the suction cup seat is attached to the bottom surface of the shell.

[0013] Furthermore, a limiting enclosure is provided in the shell, and the limiting enclosure surrounds the periphery of the release switch, and the outer wall of the release switch contacts the inner wall of the limiting enclosure.

[0014] Furthermore, there is a movable gap between the other side of the blind hole column opposite to the through hole and the inner wall of the release switch.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] By pressing the release switch, the blocking piece moves away from the through hole, and a gap is formed between the blocking piece and the through hole. Air enters the blind hole column and the through hole through the gap and finally enters the suction cup, so that the pressure difference between the inside and the outside is balanced, so that the suction cup can be easily peeled off from the fixed surface. The release switch is connected to the elastic part. Only by releasing the release switch, the release switch will automatically reset under the action of the elastic force, and the blocking piece will block the through hole again, which will not affect the next installation on the fixed surface.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 3, shows an easily peelable adsorption-type wireless charging device provided by an embodiment of the present utility model, comprising a wireless magnetic induction charging coil and a shell 1, the adsorption-type wireless charging device also comprising a suction cup 2, a release switch 3, a blocking member 4 and an elastic member 5, the shell 1 is provided with a fixing block 13, the suction cup 2 is attached to the bottom surface of the shell 1, the suction cup 2 is provided with a through hole 21, the shell 1 is provided with a blind hole column 14 at a position corresponding to the through hole 21, one end of the release switch 3 extends out of the side of the shell 1, the other end of the release switch 3 extends into the shell 1 and is connected to one end of the elastic member 5, the other end of the elastic member 5 is connected to the fixing block 13, the blocking member 4 is fixed to the release switch 3, and a through hole 141 is defined on the side wall of the blind hole column 14. In a natural state, the blocking member 4 blocks the through hole 141 under the action of the elastic member 5, and the blocking of the through hole 141 by the blocking member 4 is released by pressing the release switch 3, so that gas enters the suction cup 2 through the blind hole column 14.

[0024] Specifically, the release switch 3 includes a pressing part and a transmission part connected together. The pressing part is exposed outside the shell 1 for pressing. The transmission part has a bending structure. The bending structure is arranged around the blind hole column 14 so that the pressing direction of the release switch 3 is consistent with the movement direction of the blocking part 4. When pressed, the blocking part 4 moves in a direction away from the through hole 141.

[0025] In some specific embodiments, when the suction cup 2 is adsorbed on the fixed surface, the release switch 3 is pressed and not released, the release switch 3 pushes the elastic part 5, the elastic part 5 contracts, and the release switch 3 drives the blocking part 4 to turn from blocking the through hole 141 to disengaging from the through hole 141 under the action of the elastic part 5. The outside air flows into the through hole 141 and then enters the adsorption chamber 22 of the suction cup 2 through the through hole 21. At this time, the atmospheric pressure difference between the inside and outside of the adsorption chamber 22 is balanced, and the wireless charging device can be easily removed from the fixed surface. After removal, the release switch 3 is released, and the elastic part 5 automatically recovers under the action of the elastic force, and the release switch 3 is reset. Under the action of the elastic part 5, the release switch 3 drives the blocking part 4 to turn from disengaging from the through hole 141 to blocking the through hole 141.

[0026] Specifically, one end of the blocking member 4 facing the inner wall of the release switch 3 is a round rod, and the inner wall of the release switch 3 has a round hole. The round rod and the round hole are interference fit to fix the blocking member 4 to the inner wall of the release switch 3.

[0027] Specifically, the through hole 141 is a tapered structure that is larger on the outside and smaller on the inside, and the end of the sealing member 4 facing the blind hole column 14 is a tapered plug corresponding to the tapered structure. When the release switch 3 is pressed, the tapered plug translates in a direction away from the tapered structure, and a gap appears between the sealing member 4 and the through hole 141.

[0028] In some specific embodiments, multiple groups of corresponding release switches 3, blocking members 4, blind hole columns 14, elastic members 5 and through holes 21 can be arranged along the circumferential edge of the lower shell 12. The specific assembly method of each group will not be repeated here. The purpose is to facilitate the release of the blocking member 4 on the through hole 141 by pressing the release switch 3 in other directions of the adsorption-type wireless charging device, so that the gas enters the suction cup 2 through the blind hole column 14, thereby being easily peeled off. It can be pressed in multiple directions, which is more convenient to use.

[0029] Specifically, the sealing member 4 and the suction cup 2 are both flexible silicone bodies. The suction cup 2 includes a suction cup seat and an arc-shaped suction cup edge integrally formed with the suction cup seat. The suction cup seat is attached to the bottom surface of the housing 1. Preferably, the suction cup seat is attached to the entire bottom surface or at least the central portion, and the arc-shaped suction cup edge and the suction cup seat form a suction cavity 22.

[0030] Specifically, the release switch 3 is provided with an elastic member slot 31, and the elastic member 5 is disposed within the elastic member slot 31. One end of the elastic member 5 abuts against the bottom of the elastic member slot 31, while the other end protrudes from the notch of the elastic member slot 31 and abuts against the fixed block 13 within the housing 1. In some specific embodiments, the elastic member 5 is preferably a spring, and preferably, two elastic member slots 31 are symmetrically arranged on the left and right sides of the release switch 3, respectively, with two sets of springs placed in corresponding elastic member slots 31.

[0031] Specifically, the housing 1 is further divided into an upper housing 11 and a lower housing 12 , and the upper housing 11 and the lower housing 12 are connected via a rotating shaft.

[0032] More specifically, the wireless magnetic induction charging coil is divided into a first wireless magnetic induction charging coil and a second wireless magnetic induction charging coil. The first wireless magnetic induction charging coil is located in the upper shell 11 and is used to charge the mobile phone. The second wireless magnetic induction charging coil is located in the lower shell 12 and is used to charge the earphones. The lower shell 12 also includes a charging interface 6, which is used to power the adsorption-type wireless charging device.

[0033] Specifically, a limiting enclosure 15 is further provided in the housing 1 . The limiting enclosure 15 surrounds the periphery of the release switch 3 , and the outer wall of the release switch 3 contacts the inner wall of the limiting enclosure 15 .

[0034] Specifically, there is a movable gap between the other side of the blind hole column 14 opposite to the through hole 141 and the inner wall of the release switch 3 so that the release switch 3 can move relative to the blind hole column 14 and thereby drive the blocking member 4 to move relative to the through hole 141 .

[0035] To sum up, by pressing the release switch 3, the blocking member 4 moves in the direction away from the through hole 141, and the blocking member 4 is separated from the through hole 141 to form a gap. The air enters the blind hole column 14 and the through hole 21 through the gap, and finally enters the adsorption chamber 22, so that the pressure difference inside and outside the adsorption chamber 22 is balanced, so that the suction cup 2 can be easily peeled off from the fixed surface, and the release switch 3 is connected to the elastic member 5. You only need to release the release switch 3. Under the action of the elastic force, the release switch 3 will automatically reset, and the blocking member 4 will block the through hole 141 again, which will not affect the next installation on the fixed surface. It is practical and easy to use.

[0036] It should be noted that the present invention is not limited to the above-mentioned embodiments. According to the creative spirit of the present invention, those skilled in the art can also make other changes. These changes made according to the creative spirit of the present invention should be included in the scope of protection required by the present invention.
