Locking mechanism, on-board battery swapping system and vehicle

By designing the roller and linkage structure of the locking mechanism, the lock hook is prevented from retracting under external impact, thus solving the problem of easy passive unlocking of the locking mechanism. This improves the safety of the vehicle battery swapping system and the reliability of the battery box's locking, and enables reliable locking status detection.

AI Technical Summary

Technical Problem

In existing technologies, locking mechanisms are easily unlocked passively under external impact, leading to locking failure, which poses a safety hazard, especially when the vehicle is bumpy or vibrating during operation.

Method used

A locking mechanism is designed, including a mounting base, a telescopic drive component, a connecting rod, a locking hook, and a roller. By changing the position of the roller and designing the connecting rod, the locking hook is ensured not to retract under external impact, preventing the locking mechanism from being passively unlocked. The status is detected by a Hall effect proximity switch to ensure the reliability of the locking mechanism.

Benefits of technology

It effectively prevents the locking mechanism from being passively unlocked under external impact, improving system safety and battery box locking reliability. At the same time, it has a simple structure, high reliability, convenient installation and maintenance, and low cost.

Abstract

This utility model discloses a locking mechanism, an on-board battery swapping system, and a vehicle. The locking mechanism includes a mounting base, a telescopic drive component, a connecting rod, a first pin, and a locking hook. The mounting base has a vertical groove. The telescopic drive component includes an output shaft. The bottom of the locking hook is rotatably connected to the mounting base. One end of the connecting rod is hinged to the locking hook, and the other end of the connecting rod is sleeved on the first pin. The output shaft is connected to the first pin, and a roller is sleeved on the first pin, rollingly connected to the vertical groove. The locking mechanism has a locked state and an unlocked state. In the locked state, the roller is in a first position; in the unlocked state, the roller is in a second position. The roller has a third position between the first and second positions. When the roller is in the third position, the extension direction of the connecting rod is perpendicular to the extension direction of the output shaft. In this embodiment of the utility model, the locking mechanism can be prevented from being passively unlocked in case of accidental events.
