[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the temperature in the battery box is detected by a temperature detector. When the temperature reaches a preset threshold, the temperature detector transmits a signal to the controller to start the heat dissipation fan. The operation of the heat dissipation fan allows external air to enter the battery box through the air inlet window and be discharged to the outside through the air outlet window. The air will take away the heat of the inner heat sinks of the first protective baffle, the second protective baffle, and the third protective baffle when passing through the inside of the battery box, so as to cool the battery. The heat generated by the battery during the operation of the electric vehicle is discharged in time, which plays a protective role for the battery. In cold weather, if the temperature detected by the temperature detector does not reach the preset threshold, the heat dissipation fan will not be started, which is convenient for ensuring the charging environment in cold weather, and is conducive to effective charging, avoiding the failure of charging at low temperature, thereby facilitating the detection of the temperature in the battery box and performing timely heat dissipation operations;

[0019] 2. In the present invention, when it is necessary to disassemble and replace the battery, the staff pulls the pull rods corresponding to the left and right sides of the fixed cover plate by hand, so that the pull rods move relative to each other, so that the pull rods drive the positioning rods to slide inwardly of the positioning member, thereby pulling the positioning rods out of the positioning sleeves, which is convenient for the staff to take out the fixed cover plate from the battery box to replace the battery. When installing the replaced new battery, the fixed cover plate is installed on the top of the battery. The staff loosens the pull rods, and the positioning rods are inserted into the adjacent positioning sleeves under the elastic action of the reset spring, so that the fixed cover plate positions and fixes the battery, which is convenient for the staff to install;

[0020] 3. In the present invention, when installing the battery, the first protective partition, the second protective partition, and the third protective partition at the bottom of the fixed cover plate are respectively installed in contact with the corresponding battery, so that the first protective partition, the second protective partition, and the third protective partition are installed between the batteries, so that the battery in the battery box is fixed, and the clamping block contacts and squeezes the battery. When the electric vehicle is traveling on a rough road, the first protective partition, the second protective partition, and the third protective partition can effectively prevent the batteries from colliding with each other due to bumps, thereby avoiding safety hazards such as short circuits and damages that may be caused thereby. The design not only extends the service life of the battery, but also improves the safety performance of the entire electric vehicle. The first protective baffle, the second protective baffle and the third protective baffle also have certain heat insulation and flame retardancy, which can reduce the fire risk caused by overheating of the battery to a certain extent. The first protective baffle, the second protective baffle and the third protective baffle at the bottom of the fixed cover plate can protect the battery, provide a strong guarantee for the safe driving of the electric vehicle, thereby preventing the batteries from colliding with each other, protecting the batteries during driving, reducing the spontaneous combustion caused by collision, and increasing the safety of electric vehicles.

During driving or charging, the battery box is checked by the temperature detector 14 2 is detected. When the temperature reaches the preset threshold, the temperature detector 14 transmits a signal to the controller to start the cooling fan 9. The operation of the cooling fan 9 allows external air to enter the battery box 2 through the air inlet window 7 and be discharged to the outside through the air outlet window 8. In the process of air passing through the inside of the battery box 2, the air will take away the heat of the inner heat sinks of the first protective baffle 16, the second protective baffle 19, and the third protective baffle 20, so as to cool the battery 10 and discharge the heat generated by the battery 10 in time, thereby protecting the battery 10.
