[0002] In recent years, explosion-proof electric rubber-tired vehicles have gained market favor in the field of auxiliary transportation in coal mines due to their zero emissions and compliance with environmental protection requirements. As the technology of explosion-proof electric vehicles matures, their market is gradually emerging. New explosion-proof lithium battery standards have also paved the way for the research and development of explosion-proof electric vehicles, and their proportion in the total number of trackless rubber-tired vehicles is increasing year by year, indicating a promising market prospect. Explosion-proof electric personnel transport vehicles, modified from existing diesel rubber-tired vehicle models, have a large overall weight, lack lightweight design, and some still use small-capacity batteries, resulting in insufficient range and failing to meet usage requirements. Vehicles modified from road passenger vehicles have significantly improved in terms of overall weight, but their low structural strength also makes them unsuitable for use in the special underground environment. Therefore, this utility model proposes an explosion-proof electric personnel transport vehicle for mining. Utility Model Content

[0014] The present invention will be further described in detail below with reference to specific embodiments.

[0015] Example:

[0016] like Figure 1 and Figure 2 As shown, this utility model discloses an explosion-proof electric personnel transport vehicle for mining, comprising a frame 1, a single-motor four-wheel drive system 2, a multi-link suspension system 3, a body 4, and an electrical system 5. The single-motor four-wheel drive system 2 is connected to the bottom of the frame 1 via the multi-link suspension system 3. The body 4 is located on the upper part of the frame 1, and the electrical system 5 is located on the frame 1. The body 4 is an integrated structure, including a driver's cab 41 and a passenger compartment 42 connected to the driver's cab 41. The electrical system includes a vehicle controller 51, a high-voltage controller 52, a motor control box 53, and a drive power supply box 54. The high-voltage controller 52 and the motor control box 53 are connected to the vehicle controller 51, and the drive power supply box 54 supplies power to the electrical system 5 and the single-motor four-wheel drive system 2. The body 4 adopts an integrated structure, and the driver's cab 41 and the passenger compartment 42 are connected. The body 4 has a more compact structure, a smaller turning radius, and is suitable for underground working environments.

[0017] There are four drive power boxes 54, which are symmetrically arranged on both sides of the middle part of the frame 1. Each drive power box 54 is installed in two layers, so as to balance the front and rear axle loads and the left and right loads are even, making the vehicle run more smoothly.
