[0028] With the development of mobile phone charging functions, wireless charging has gradually become popular. In order to improve the user experience, vehicles are usually equipped with wireless charging devices for wireless charging of mobile phones. At present, the wireless charging device in the vehicle includes an upper shell, a PCB (Printed Circuit Board) board, a cast aluminum lower shell, a power interface and a PCB board mounting structure, and the power interface and the PCB board mounting structure are both located inside the shell. However, the structure of the above-mentioned wireless charging device is complex, and the PCB board mounting structure will occupy more space in the height direction, resulting in a larger overall volume of the wireless charging device, which occupies a large space and is not conducive to being arranged in the back row of the vehicle. In order to solve the above problems, the embodiment of the utility model proposes a wireless charging device and a car.

[0029] First, refer to Figure 1 , Figure 3 and Figure 4 The embodiment of the utility model proposes a wireless charging device, including an upper cover 1, a base 4, a circuit board 5 and a lower shell 6, the base 4 is located between the upper cover 1 and the lower shell 6, the upper cover 1 is provided with a first ear 11, and the lower shell 6 is provided with a second ear 61 corresponding to the first ear 11; the first ear 11 is provided with a clamping hole 111, the second ear 61 is provided with a clamping portion 611, the clamping hole 111 is clamped with the clamping portion 611, the base 4 is provided with a limiting protrusion 41 protruding away from the second ear 61, and the edge of the circuit board 5 is provided with a limiting notch 52 matched with the limiting protrusion 41.

[0030] Specifically, the wireless charging device can be installed in a car, that is, the wireless charging device is a vehicle-mounted wireless charging device. The upper cover 1 and the lower shell 6 together constitute the outer shell of the wireless charging device. The upper cover 1 is made of plastic, the base 4 can be made of aluminum, and the base 4 is manufactured by casting. Electronic components and circuits related to wireless charging are arranged on the circuit board 5. The first ear 11 and the second ear 61 are both arranged vertically. The position of the limiting protrusion 41 corresponds to the position of the first ear 11 and the second ear 61, refer to Figure 4 The second ear 61 is located between the limiting protrusion 41 and the first ear 11, and the first ear 11 is located at the outermost side. Figure 1 The limiting protrusion 41 cannot be seen from the outside, so that the appearance of the wireless charging device is simple.

[0031] The number and position of the first ears 11 on the upper cover 1 can be set according to actual needs. For example, four first ears 11 can be set on the upper cover 1, and the four first ears 11 are respectively located on both sides of the width direction of the wireless charging device. Figure 1 and Figure 4 The direction indicated by the arrow B in the figure. Each first support ear 11 is provided with a clamping hole 111. The number of second support ears 61 is equal to the number of first support ears 11, and the position of the second support ears 61 corresponds to the position of the first support ears 11, and each second support ear 61 is provided with a clamping portion 611. The number of limiting protrusions 41 is equal to the number of second support ears 61, and the position of the limiting protrusions 41 corresponds to the position of the second support ears 61.

[0032] The number of the limiting protrusions 41 can be four, and the four limiting protrusions 41 are respectively located on both sides of the width direction of the wireless charging device. At this time, the number of the limiting notches 52 is also four, and the four limiting notches 52 are respectively located on both sides of the width direction of the wireless charging device. The limiting protrusions 41 cooperate with the limiting notches 52 to achieve the limiting of the circuit board 5. The limiting protrusions 41 are specifically used to limit the movement of the circuit board 5 in the horizontal direction. The base 4 can achieve the matching of the circuit board 5 through the limiting protrusions 41 thereon, and the structure is simple, so that the mold design for manufacturing the base 4 is simple, reducing the difficulty of the die-casting process.

[0033] In the embodiment of the utility model, the limiting protrusion 41 cooperates with the limiting notch 52 on the edge of the circuit board 5 to realize the limiting of the circuit board 5. The limiting protrusion 41 protrudes away from the second ear 61, that is, the limiting protrusion 41 and the limiting notch 52 cooperate in the horizontal direction, so that the limiting structure of the circuit board 5 does not occupy the space in the height direction, and because the position of the limiting protrusion 41 corresponds to the position of the first ear 11 and the position of the second ear 61, and the limiting protrusion 41 is protruding inward, it will not occupy the space in the length and width direction, thereby making the overall volume and occupied space of the wireless charging device smaller, thereby facilitating the arrangement of the wireless charging device in the front and rear rows in the vehicle. In addition; the position of the limiting protrusion 41 on the base 4 corresponds to the position of the first ear 11 and the position of the second ear 61, and the limiting protrusion 41 is not visible from the appearance, so that the appearance of the wireless charging device is simple; the upper cover 1 is snapped with the lower shell 6, which is convenient for the installation and removal of the upper cover 1 and the lower shell 6.
