Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted power supply reinforcement, and more specifically, to a vehicle-mounted reinforced integrated power supply. Background Art

[0002] The main function of the vehicle power supply is to convert the vehicle's DC power supply into AC power supply, providing a stable power supply for various electrical devices in the car. The vehicle power supply, also known as a power inverter, has the core function of converting the car's 12V DC power supply into a 220V AC power supply. In order to improve the stable power output during power supply, the vehicle power supply transmits the converted power to the battery pack after the DC and AC conversion is completed, and then the battery pack is used to stably supply power to the vehicle's electrical appliances.

[0003] In the prior art, the vehicle-mounted power supply usually needs to be fixed in the power supply chassis. However, in order to meet the endurance of the power supply, multiple battery packs are now mostly connected in series to increase the power reserve. However, long-term use will also cause some battery packs to be damaged. During maintenance, all battery packs need to be removed and tested in turn. The screws used for fixing will wear out due to continuous twisting, resulting in failure of fixation. Based on the above problems, we provide a vehicle-mounted reinforced integrated power supply. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a vehicle-mounted reinforced integrated power supply.

[0005] The vehicle-mounted reinforced integrated power supply provided by the present invention adopts the following technical solution:
