Description

Wireless charging device and electric vehicle Technical Field The utility model relates to the technical field of wireless charging of electric vehicles, in particular to a wireless charging device and an electric vehicle. Background Along with the acceleration of the urban traffic greening and intelligent processes, the two-wheel electric vehicle has become an important tool for short-distance travel due to the characteristics of convenience and environmental protection. In recent years, wireless charging technology has been widely focused in the field of electric vehicles because of the advantages of no plugging and unplugging and high safety. However, the wireless charging scheme of the existing two-wheeled electric vehicle still faces a significant technical bottleneck. Currently, the mainstream wireless charging devices in the market generally adopt a split type design, that is, an induction coil of a charging receiver is separated from a receiving box, wherein the coil is integrated in a heel brace structure, and the receiving box needs to be built in a vehicle body. The design leads to the fact that a user has to structurally reform the vehicle (such as opening a vehicle shell, adjusting a circuit layout and the like) when installing, so that the vehicle is complex in operation, time-consuming and labor-consuming, the tightness and the original line safety of the vehicle can be possibly damaged, and when the user changes the vehicle due to the non-integrated design of the receiver and the heel support, the heel support and the receiving device which are adapted to a new vehicle model have to be synchronously replaced, so that the vehicle is poor in universality and high in cost. Disclosure of utility model The utility model mainly aims to provide a wireless charging device and an electric vehicle, and aims to solve the problems of complex wireless charging installation and poor suitability of the existing electric vehicle. To achieve the above object, the present utility model provides a wireless charging device, comprising: the mounting box is internally provided with a mounting cavity; the transformation module is fixedly arranged in the installation cavity; The wireless charging module is arranged in the installation cavity and is electrically connected with the transformation module. Optionally, wireless charging module includes roll-up device and wireless receiving box that charges, roll-up device includes rotation wheel and elastic cable, the one end of elastic cable is around locating rotation wheel, the other end with wireless receiving box that charges is connected, roll-up device is used for the drive wireless receiving box that charges is automatic to be rolled up and is received in the installation cavity or extend to the installation box outside. Optionally, be provided with charging coil and magnetism in the wireless receiving box that charges and inhale the piece, magnetism inhale the piece along wireless circumference setting of receiving box that charges, magnetism inhale the piece and be used for with outside wireless transmitting terminal magnetism of charging and inhale the alignment. Optionally, the magnetic attraction member is a ring magnet. Optionally, the front end both sides of installation cavity are provided with spacing portion, spacing portion is used for limiting the position of wireless charging receiving box. Optionally, a plurality of heat dissipation holes are formed in one surface of the mounting box. Optionally, the wireless charging device further comprises a plug, one end of the plug is electrically connected with the voltage transformation module, and the other end of the plug is electrically connected with an external power supply. In order to achieve the above object, the present utility model further provides an electric vehicle, which includes any one of the above wireless charging devices, wherein the wireless charging device is detachably connected to a vehicle body. The wireless charging device for the electric vehicle has the beneficial effects that the problems of complex installation and poor suitability of wireless charging of the existing electric vehicle are solved. The wireless charging module and the transformation module are integrated in the installation box, the detachable installation box is adopted to match with the telescopic adjusting function of the elastic cable, the vehicle is not required to be structurally modified, wireless charging can be realized through connection of the plug and an external power supply, the charging step is simplified, the installation convenience is improved, and secondly, the transformation module is adopted to meet the charging requirements of different vehicles, so that the device can be adapted to installation of different vehicle types, and the practicability of the device is enhanced.
