[0020] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0021] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.
[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] refer to Figure 1 - Figure 3 As shown, this utility model embodiment provides a wireless charging receiver structure, including a cover plate 1, a receiver assembly 2, and a heat dissipation assembly 3 for mounting and fixing an electric scooter on the receiver assembly 2.
[0024] The receiving end assembly 2 includes a U-shaped box 201 rotatably connected to the bottom end of the cover plate 1. A first U-shaped groove 202 is provided inside the U-shaped box 201. A charging coil 203 is provided inside the first U-shaped groove 202. A charging end 201a is provided on the outer surface of the U-shaped box 201.
[0025] When the scooter needs charging, firstly, the charging coil 203 is bent and placed into the first U-shaped groove 202 of the U-shaped box 201. Then, the scooter handlebar is fixed to the charging end 201a in the recess of the U-shaped box 201, so that the charging coil 203 placed inside the first U-shaped groove 202 is parallel to the external coil. Then, the charging coil 203 contacts the external transmitter through the charging end 201a, thereby receiving the electrical energy transmitted by the external transmitter in the form of electromagnetic waves. Then, the charging coil 203 charges the second U-shaped groove 3 through electrical connection. In the circuit board 4, the charging scooter is charged. During the charging process, the heat sink 5 begins to dissipate heat from the circuit board to ensure that the circuit board 4 does not accumulate heat and short-circuit. If the scooter cannot receive normal voltage to work when the head rotates, the handlebar of the charging scooter is rotated, which causes the handlebar of the charging scooter to drive the U-shaped box 201 to rotate. Then, when the U-shaped box 201 rotates to a certain angle within a 180° rotation range, because the charging end 201a has an arc structure and the charging coil 203 is placed inside the charging end 201a, it can still receive enough power to charge.
