Technical Field
[0001] The utility model relates to a personnel carrier in the field of new energy electric vehicles for coal mines underground, especially a mine-used pointed box-type electric vehicle for transporting personnel underground in coal mines. Background Art
[0002] The mine-used electric vehicle for transporting personnel underground in coal mines is a manned transportation device designed specifically for the complex environment underground in coal mines, and is mainly used for safely and efficiently transporting miners back and forth between the working face and the designated area above / below the well.
[0003] Among the existing mine-used electric vehicles for transporting personnel underground in coal mines, due to the limitations of the use environment of the vehicle underground, there are various types of vehicles. However, generally, the cab is flat-headed, and there is a safety hazard for the driver in case of collision; the cab is not connected to the passenger compartment, resulting in poor communication, and there is a safety hazard that passengers cannot communicate with the driver in time; the escape door of the passenger compartment is very small due to space limitations, and it is very difficult for passengers to escape in time in case of an accident; due to the limitations of the space underground in coal mines, the width of the passenger compartment is limited, and the depth of the two long benches is very small. When encountering a sharp turn, passengers are prone to slide forward; in the overall vehicle design, it is also restricted by the space underground in coal mines, and it is difficult to arrange some electrical components reasonably. Most of the battery boxes of the drive power supply are installed in the front or the back, which will cause either the front axle load or the rear axle load to be too large, affecting the handling performance of the whole vehicle, and the weight of the whole vehicle cannot be reasonably distributed, posing a safety hazard to the use performance of the whole vehicle.

The seats include seat cushions and backrests, and an included angle of 95 degrees is formed between the seat cushion and the backrest.
[0014] By adopting the above technical solution, an included angle of 95 degrees between the seat cushion and the backrest prevents passengers from sliding forward during sharp turns.
[0015] The present utility model is further configured as follows: The special-shaped longitudinal beam includes a front longitudinal beam, a middle longitudinal beam and a rear longitudinal beam. The middle longitudinal beam connects the front longitudinal beam and the rear longitudinal beam, and the horizontal plane height of the middle longitudinal beam is lower than the horizontal plane heights of the front longitudinal beam and the rear longitudinal beam. The transverse support beam is located on the middle longitudinal beam.
[0016] By adopting the above technical solution, the middle longitudinal beam is the lowest and the explosion-proof battery box body is arranged on the middle longitudinal beam, so that the vehicle center of gravity is reduced, the controllability and stability are improved, and it has the beneficial effects of simple structure, convenient installation, safety and reliability, and good versatility.
