Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted charging modules, and in particular relates to a vehicle-mounted charging module. Background Art

[0002] In the prior art, it is often necessary to charge mobile phones and smart mobile devices in cars or other means of transportation, and the general charging method is mainly to obtain power through two methods. One charging method is to directly connect the USB port from the circuit in the car and directly obtain 5V voltage. This method occupies the data interface, and the voltage provided is generally higher than the optimal voltage for mobile phone charging. Long-term use will damage the life of the battery. During the charging process, a longer wire is required to connect the mobile phone, generally about 0.5-1.5m. When using the mobile phone while driving, there may be a danger of the wire being entangled in the shift handle; another method is to use wireless charging, set the charging module inside the car body, and perform wireless charging through a traditional charging module. In this method, the charging coil is often set inside the car body, and different car body molds need to be set for different car models to pre-install the charging module, which is very unfavorable for the heat dissipation of the charging module. When the charging module is damaged, the car body needs to be completely disassembled before the charging module can be replaced or repaired, which is very inconvenient when maintaining the charging module.

[0003] The patent application number 201821001111.4 discloses a vehicle-mounted wireless charging device and a charging module, wherein the wireless charging device comprises a charging carrier plate, the outer peripheral wall structure of the charging carrier plate is customized according to the inner shell of the vehicle model, and a through hole is opened on the charging carrier plate; a wireless charging module, the upper and lower side surfaces of the wireless charging module are exposed at the opening surface of the through hole, and the wireless charging module is pre-produced as a standard size unit. When assembling the wireless charging device, it is only necessary to directly assemble the standardized wireless charging module with the charging carrier plate, and then assemble the vehicle, thereby realizing large-scale pre-production of wireless charging modules, high assembly production efficiency, and easier disassembly and replacement.

[0004] The above technical solution produces the charging module in a modular manner so that the charging module is suitable for installation in cars with different signals. However, since the charging module is still fixed to the mounting base, the car shell still needs to be completely disassembled when disassembling the battery module, which makes it very inconvenient to maintain the charging module.

[0007] (2) Technical solution

[0008] In order to solve the above technical problems, the utility model provides a vehicle-mounted charging module, which includes a mounting seat and a wireless charging plate that is detachably embedded and fixed in the mounting seat, the top of the mounting seat is provided with a mounting groove, and both ends of the mounting seat are embedded and fixed with heat sinks, the bottom end of the wireless charging plate is fixed with a charging module body that is fitted and plugged into the mounting groove, both ends of the charging module body are provided with positioning grooves, and the bottom end of the charging module body is embedded with a heat conducting plate that contacts the heat sink, telescopic grooves are provided on both sides of the inner wall of the mounting groove, a positioning block that is elastically arranged in the telescopic groove and is clamped with the positioning groove, and an electromagnetic plate for attracting the positioning block is fixed to the inner wall of the telescopic groove.

The spring in the telescopic groove pushes the positioning block to be inserted into the positioning groove, thereby keeping the charging module body fixed in the mounting groove. When disassembling the charging module body, the electromagnetic plate is started to attract the magnetic rod on the side wall of the positioning block, and the positioning block is driven to move out of the positioning groove and shrink into the telescopic groove during the attraction process, thereby improving the convenience of installing and disassembling the charging module body.

[0010] Preferably, a connection terminal electrically connected to the charging module body is fixed to the bottom wall of the mounting groove, and heat absorbing plates are fixed to both sides of the inner wall of the mounting groove.
