An electric vehicle battery placement structure with cushioning effect

Abstract

The invention discloses a battery placement structure for an electric vehicle with a buffer effect, which includes a vehicle frame, a battery placement groove in the middle of the vehicle frame, a battery box protective case inserted and fixed in the battery placement groove, and a battery box protective case. There are multiple screw through holes on the side wall, and there are also multiple through holes on the side wall of the battery placement groove. The through holes correspond to the screw through holes one by one. The ball plunger is screwed into the screw through hole, and the battery The box is placed in the battery box protective case, the battery box has a ring-shaped positioning part on the outer wall of the middle part, the steel ball of the ball plunger is nested in the concave hole on the ring-shaped positioning part, and the bottom surface of the battery box protective case is fixed. A buffer spring, the buffer pad is placed on the buffer spring, and the battery box is pressed against the buffer pad. When the electric vehicle is running, it makes the battery box have a buffer effect and improves the service life. At the same time, the battery box has vent holes, which can discharge the heat in the battery box to a certain extent and improve safety.

Description

[0001] Technical field: [0002] The invention relates to the technical field of electric vehicle equipment, in particular to an electric vehicle battery placement structure with a buffer effect. [0003] Background technique: [0004] At present, electric vehicles have been very popular in China. Due to their convenient charging and simple operation, they have replaced bicycles in people's status. However, electric vehicles need electricity as power, that is, they must be powered by batteries, and the existing batteries It is installed in the battery box, and the battery box is fixed in the battery slot on the frame. It is generally fixedly connected, so that when the car vibrates, the battery box will also vibrate, and because the battery box is hard-connected to the car In the frame, there is no other buffer device. After a long time, it will have an impact on the use of the battery. It is easy to make the connecting wires welded in the battery detached, making the electric ...

[0004] At present, electric vehicles have been very popular in China. Due to their convenient charging and simple operation, they have replaced bicycles in people's status. However, electric vehicles need electricity as power, that is, they must be powered by batteries, and the existing batteries It is installed in the battery box, and the battery box is fixed in the battery slot on the frame. It is generally fixedly connected, so that when the car vibrates, the battery box will also vibrate, and because the battery box is hard-connected to the car In the frame, there is no other buffer device. After a long time, it will have an impact on the use of the battery. It is easy to make the connecting wires welded in the battery detached, making the electric car unable to open and affecting the use. Moreover, there is no What kind of ventilated structure, when the electric vehicle is used and charged, the temperature in the battery box will soar, and when the old battery is used for a long time, it will cause safety hazards such as explosion due to excessive temperature
