Description

TECHNICAL FIELD

[0001] The utility model relates to electric automobile battery swap technical field especially relates to an angle measurement and angle reset device. BACKGROUND

[0002] With the vigorous development of electric vehicle market, the demand of consumers for improving vehicle endurance and shortening charging time is increasingly urgent. Under this background, battery swap technology as an innovative energy supply method is gradually becoming an important way to solve the endurance anxiety of electric vehicles and accelerate charging efficiency. Among them, the chassis battery swap technology occupies a dominant position in the market because of its high efficiency and convenience.

[0003] The core of the chassis battery swap technology lies in the efficient battery exchange process between the vehicle and the battery swap station. Specifically, when the electric vehicle enters the battery swap station, through guidance and positioning, the battery (or battery compartment) at the bottom of the vehicle can be smoothly unlocked and released from the bottom of the vehicle. Subsequently, the transfer trolley quickly picks up the battery (or battery compartment) and transports it to the battery swap cabinet in the battery swap station for charging or storage, while taking out a fully charged battery from the battery swap cabinet for reverse installation.

[0004] However, although the chassis battery swap technology shows great application potential, it still faces a key challenge in actual operation: parking accuracy problem. Since the parking of the vehicle in the battery swap station often cannot reach the completely standard angle, this small angle deviation is significantly amplified in the battery swap process, causing the transfer trolley to fail to successfully complete the exchange when trying to install the battery into the battery swap cabinet or install the fully charged battery back into the vehicle bottom due to the angle deviation of the battery, thereby affecting the battery swap efficiency and user experience.

[0005] Of course, such a problem is not limited to the field of battery swap alone, in real life, as long as the process involves handling, there may be a problem of inaccurate handling due to angle deviation. UTILITY MODEL CONTENT
