[0002] Explosion-proof electric trackless vehicles are used in coal mines or underground environments with explosive gases such as methane. The existing technology mainly switches the vehicle's high and low speeds by manually adjusting the shift handle according to the road conditions of the vehicle to meet different operating conditions.

The gearbox is also installed with a high-speed solenoid valve and a low-speed solenoid valve for controlling its high and low gear positions.
