Problems solved by technology
However, electric vehicles currently on the market still have a common defect: the cruising range is relatively short. The scope of use of the car has been greatly limited
[0003] In order to solve the above problems, the main measures taken at present are to continuously improve the implementation of charging in various places and establish charging stations with power battery charging equipment. However, even if charging stations are used to charge the power batteries of electric vehicles, there is still the problem that the charging time is too long Question: It takes about 8 hours to fully charge in slow charging mode (i.e. civilian voltage 220V); it also takes about 3 hours in fast charging mode (i.e. industrial voltage 380V)
Therefore, when the battery pack is replaced with this bolt fixing structure, the operation is complicated and time-consuming

The invention provides a chassis-type power battery rapid locking mechanism. The chassis-type power battery rapid locking mechanism comprises a battery pack and a locking installation support frame arranged on an electric car chassis, wherein a first lateral surface and a second lateral surface of the battery pack are opposite and are respectively and fixedly provided with at least one locking buckle, each locking buckle is provided with a locking buckle hole, the locking installation support frame is provided with locking mechanisms with the same number as the locking buckles, and each locking mechanism is provided with a spring bolt matched with each locking buckle. When the battery pack is lifted and installed, the spring bolts can be buckled in the locking buckle holes, so that the battery pack is fixed. According to the chassis-type power battery rapid locking mechanism, the battery pack is fixed or released through the locking method that the spring bolts are matched with the locking buckles, compared with an existing battery pack replacing method, the replacement of the battery pack is low in complexity, and the replacement time is obviously shortened.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a chassis-type power battery quick-change locking mechanism. Background technique [0002] An electric vehicle refers to a vehicle that is powered by a vehicle-mounted power supply, uses a motor to drive the wheels, and meets the requirements of road traffic and safety regulations. It uses electricity stored in the power battery to start. Electric vehicles do not have an internal combustion engine, and will not produce exhaust pollution when the vehicle is running, which is very beneficial to environmental protection and air cleanliness, almost "zero pollution". In addition, the noise of electric motors is smaller than that of internal combustion engines. It can be seen that compared with traditional vehicles, electric vehicles have the advantages of environmental protection and cleanliness, low or no noise in operation, and their development prospects are very bright....
