The invention discloses an electric vehicle device for deflating a rear tire during emergency braking. The device comprises a vehicle frame, two rear wheel supporting frames are fixedly arranged at the lower end of the vehicle frame in a front-back symmetrical mode, a rear wheel rotating shaft is arranged between the rear wheel supporting frames in a rotating mode, an installation ring is fixedlyarranged on the rear wheel rotating shaft, and six rear wheel supports are fixedly arranged on the installation ring in an annular array mode. When an electric vehicle runs on a slippery road surfaceor runs at a high speed, the safety of a driver can be guaranteed only by shortening the braking distance during braking action, the device can deflate a rear tire while locking a brake disc, the contact area between the rear tire and the ground is increased, the braking effect is greatly improved, and the braking distance is shortened; in the continuous driving process, the vehicle can automatically inflate the rear tire, and the tire pressure is normal in the driving process.

    本发明公开了一种紧急刹车时后胎放气的电动车装置,包括车架,所述车架下端前后对称固定设有两个后轮支撑架,所述后轮支撑架间旋转设有后轮转轴,所述后轮转轴上固定设有安装环,所述安装环上环形阵列固定设有六根后轮支架,在电动车行驶过程中,遇到湿滑路面或者在高速行驶过程中,在进行刹车制动动作时,需要缩短制动距离才能保障驾驶员的安全,本设备在锁死刹车盘的同时会对后胎进行放气动作,增加了后胎与地面的接触面积,大大提高了制动效果,缩短制动距离,在继续行驶过程中,车辆会自动对后胎进行充气,保证行驶过程中的胎压正常。
