Technical Field
[0001] This utility model relates to the field of wireless charging device technology, and specifically to a high heat dissipation wireless charging device. Background Technology
[0002] Traditional wireless charging devices generally suffer from problems such as low heat dissipation efficiency and limited bracket orientation adjustment. Magnetic induction charging coils generate a lot of heat when working, and the heat accumulates in local areas, making it difficult to achieve uniform heat dissipation. If heat dissipation is only relied on the shell, it will easily lead to overheating of the device, affecting the charging rate and posing safety hazards, which in turn affects the charging stability and device lifespan. The traditional rigid bracket design makes it difficult for the charging device angle to adapt to different scenario requirements. Therefore, there is an urgent need for a wireless charging device with high heat dissipation to solve the above problems. Utility Model Content

The wireless charging housing includes a front cover, a front shell connected to the bottom of the front cover, and a rear shell connected to the front shell. The high-heat-dissipation wireless charging device also includes a flexible bracket, multiple thermally conductive adhesives, and a fixing base.

[0006] Furthermore, the flexible support and the fixed base are detachably connected by Velcro, and the fixed base has a removable adsorption element on the side facing away from the flexible support so that the position of the fixed base can be repeatedly adjusted.
[0007] Furthermore, the flexible support can be bent arbitrarily to move the wireless charging housing in any direction.
[0008] Furthermore, the outer edge of the front shell is provided with an annular groove, and an annular magnet is provided in the annular groove. The middle part of the front shell is provided with a receiving groove, and the magnetic induction charging coil is placed in the receiving groove.

[0009] Furthermore, the metal sheet has a clearance hole corresponding to the through hole, and the wires of the magnetic induction charging coil pass through the through hole and the clearance hole in sequence to be electrically connected to the wires of the PCB board.
[0010] Furthermore, the metal sheet is provided with multiple positioning holes, the front shell is provided with limiting holes corresponding to the positioning holes, and the wireless charging housing is also provided with limiting posts. The upper end of the limiting post is installed in the limiting hole, and the lower end of the limiting post is installed in the positioning hole so that the positioning hole and the limiting hole are aligned.

[0013] Furthermore, the edge of the fixing base has multiple strip-shaped notches in the circumferential direction to make the removable adsorption element adhere more firmly.
[0014] Compared with the prior art, the present invention has at least the following beneficial effects: First, this high-heat-dissipation wireless charging device uses a metal sheet bonded with thermally conductive adhesive. Heat is conducted from the magnetic induction charging coil to the metal sheet through the thermally conductive adhesive, and then diffused over a large area through the metal sheet. At the same time, the front shell is also equipped with multiple heat dissipation holes to accelerate air convection, avoid local heat accumulation, and achieve efficient heat dissipation.

The metal sheet 9 is used to achieve large-area uniform heat diffusion, and heat dissipation holes 21 are provided on the front shell 4 to accelerate air convection and thus accelerate heat dissipation.

More specifically, the metal sheet 9 is preferably an aluminum sheet.
[0023] Specifically, the front shell 4 is provided with a plurality of hooks 12, and the metal sheet 9 is provided with connecting holes 13 corresponding to the positions of each hook 12. The rear shell 5 is provided with grooves 14 corresponding to the positions of each hook 12. After the hook 12 passes through the corresponding connecting hole 13, it hooks and fixes itself with the corresponding groove 14 so that the front shell 4 and the rear shell 5 are fixedly connected.
[0024] Specifically, the flexible support and the fixed base 7 are detachably connected by Velcro 15. The fixed base 7 is provided with a removable adsorption element 16 on the side facing away from the flexible support so that the position of the fixed base 7 can be repeatedly adjusted.

The bottom of the fixed base 7 is provided with a removable adsorption element 16, which not only supports repeated adjustment of the position of the fixed base 7, but also allows the fixed base 7 to be firmly attached to the bedside, desktop, car center console, etc. The strip-shaped notches 26 of the fixed base 7 are designed so that when the fixed base 7 is pressed against the fixed surface, the removable adsorption element 16 can be squeezed into the strip-shaped notches 26, increasing the contact area between the removable adsorption element 16 and the fixed base 7, which can effectively prevent the removable adsorption element 16 from falling off.
