Battery protection device of a balancing car and a balancing car

Abstract

The invention relates to a battery protection device of a balancing car and a balancing car. The balancing vehicle comprises wheels, a vehicle shell, a base in the vehicle shell, a battery and a battery protection device, wherein the battery is fixedly arranged on the base through the battery protection device, the battery protection device comprises a cushioning material with cushioning functionand a fire-retardant refractory material, the cushioning material is wrapped outside the battery, and the refractory material is wrapped outside the cushioning material; the shape of the refractory material is a hollow cuboid, and the interior space of the refractory material is used for accommodating the battery. When the balancing car is impacted, the cushioning material can play a cushioning role, reduce the impact force on the battery, and protect the battery from being easily crashed or spontaneously ignited by the impact; at the same time, the outermost layer of refractory material can insulate the fire when the battery spontaneously combusts, play the role of flame retardant, and prevent the fire from spreading to the entire balance car and surrounding articles.

Description

technical field [0001] The solution relates to a self-balancing car, and more specifically, relates to a battery protection device for a self-balancing car and the self-balancing car. Background technique [0002] Balance car, also known as somatosensory car and thinking car, its operating principle is mainly based on a basic principle called "dynamic stability", using the gyroscope and acceleration sensor inside the car body to detect changes in the body posture , using the servo control system to precisely drive the motor to make corresponding adjustments to maintain the balance of the system. [0003] The balance car includes a car shell, a base located in the car shell, a battery, and a battery protection device, and the battery is fixedly arranged on the base through the battery protection device. The battery is the source of electric energy of the self-balancing car and one of the important components of the self-balancing car. The battery is mainly made of lithium-i...

AI Technical Summary

Problems solved by technology

[0004] The protection strength of the existing balance car battery protection device is not enough. In terms of structure, when it is hit, it cannot provide effective buffer to protect the battery; at the same time, the battery is easy to burn and catch fire when it is hit or the temperature reaches 100 ° C. The existing battery The protective device cannot be effectively flame-retardant from the material. When the battery catches fire, the fire will quickly spread to the entire self-balancing vehicle and surrounding items, causing damage to the entire self-balancing vehicle or surrounding items, and may even endanger the safety of users.
