Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted mobile phone wireless chargers, and specifically discloses a vehicle-mounted mobile phone wireless charger. Background Art

[0002] In the prior art, due to the narrow space for the installation location of the in-vehicle mobile phone wireless charger, and the distance between the bottom of the mobile phone shell and the wireless charging coil is preferably between 2mm-8mm, the wireless charger volume cannot be designed to be too large, and the internal space is even smaller. However, the inductor and charging coil on the internal PCB will generate a lot of heat during operation. If the heat is not dissipated and cooled in time, the heat will be transferred to the mobile phone, causing the mobile phone temperature to be too high and the power to be reduced, resulting in slow charging speed and long charging time. In order to solve these problems, we reduce the internal components and optimize the structure within a limited space, which not only improves the charging efficiency, but also reduces the production cost and simplifies the assembly. In view of this, the inventor proposes a car-mounted mobile phone wireless charger. Utility Model Content

[0003] The utility model aims to solve the problem of low heat dissipation efficiency of a traditional vehicle-mounted wireless charger for mobile phones.

[0004] In order to achieve the above object, the utility model provides the following basic solutions:

[0006] The principles and effects of this basic solution are:

[0007] 1. Compared with the existing technology, this device has a simple structure and ingenious design. The appearance of this self-developed in-vehicle wireless charger is similar to that on the market. In terms of internal structure, the wireless chargers on the market are divided into an upper shell, a lower shell, thermal conductive hardware, a PCB board, and a coil. The later assembly needs to be fixed with screws. During the production process, a set of plastic molds and 2 sets of hardware molds need to be manufactured. At present, the in-vehicle mobile phone wireless charger structure developed by our company is divided into an upper shell, a lower shell and a heat insulation board. No screws are required for the later assembly. The internal space uses a heat insulation board to replace the traditional internal thermal conductive hardware, separating the coil and the PCB board equipped with the inductor into two independent spaces, and leaving a distance of 6MM, and there are heat dissipation holes around. In this way, the heat can be dissipated quickly, and the heat generated by the coil and the inductor will not be transmitted to each other, which can ensure that the mobile phone can be charged quickly for a longer time.

[0008] Furthermore, the outer surface of the upper shell near the wireless coil assembly is a plastic part. Considering the sturdiness of the mobile phone, setting it as a plastic part can better protect the mobile phone and thus prevent the mobile phone from being bumped.

[0009] Furthermore, both sides of the upper shell are fixedly connected with a card block, the card block is provided with a card slot, and the lower shell is fixedly connected with a protrusion at a position corresponding to the card block, and the card slot is buckled with the protrusion, so as to realize a detachable connection between the upper shell and the lower shell.

[0010] Furthermore, two ends of the lower shell are fixedly connected with connecting pieces, the connecting pieces are metal pieces, and a plurality of mounting holes are opened on the connecting pieces, so as to realize stable mounting of the lower shell.

[0011] Furthermore, the fixing assembly includes a heat insulation board fixing part, a PCB board fixing part and a wireless coil assembly fixing part. The heat insulation board, the PCB board and the wireless coil are fixed.

[0012] Furthermore, the heat insulation board fixing member is composed of a plurality of baffles fixedly connected to the interior of the upper shell, the plurality of baffles form a frame structure, and the heat insulation board is fixed in the frame structure, so that the heat insulation board forms an independent space, thereby isolating the heat transfer between the PCB board and the wireless coil.

[0013] Furthermore, the PCB board fixing member includes a receiving block and a clamping block, the receiving block is used to receive the PCB board, and the clamping block is used to clamp the PCB board.

[0014] Furthermore, the wireless coil assembly fixing member includes a wireless coil mounting groove and a bracket receiving block, and the bracket receiving block is used to receive the wireless coil supporting bracket of the wireless coil assembly.

[0015] Furthermore, heat dissipation holes are provided around both sides of the lower shell to enhance the heat dissipation effect of the lower shell. BRIEF DESCRIPTION OF THE DRAWINGS
