Background technique

With the strengthening of the concept of environmental protection, electric vehicles have gradually become one of the main means of transportation for people to travel short distances. Among them, electric scooters are favored by people because of their small size and convenient riding. Due to the special structure of electric scooters, the bottom of the seat cushion of electric scooters is mostly designed as a rear storage box structure, and the battery of electric scooters is also installed in the rear storage box. The traditional rear storage box is an integral structure. At the same time, due to the special structure of the rear storage box, it cannot be stacked, so that the rear storage box needs to occupy a lot of space during storage and transportation. Come in great trouble. In order to fix the battery in the rear storage box, a battery pressure plate is arranged in the storage box. One side of the battery pressure plate is hinged with the rear storage box, and the other side is fixed with the rear storage box by locking bolts. The battery is installed in the rear storage box. Afterwards, the battery is pressed tightly by the rubber damping pad on the lower side of the pressure plate, but this brings inconvenience to people during the process of disassembling and assembling the battery. At the same time, the use of rubber shock pads to compress the battery has poor adaptability and poor shock absorption effect. Especially with the increase of use time, the rubber will gradually age, which will cause the compression effect and shock absorption effect to deteriorate, thus Affect the positioning and use of the battery.
