Through battery box and vehicle with same

Abstract

The invention discloses a through battery box which comprises a box body enclosed by six box surfaces, wherein one box surface is a movable box door. The box body comprises two guide rails, a plurality of pin bushes and a plurality of bolt holes. According to the through battery box, batteries are conveniently replaced, time and labor are saved, the batteries in the battery box are safe and stable, damage caused by collision is avoided, and normal functions of the batteries are ensured. The invention further discloses a vehicle with the battery box. The vehicle comprises a bottom frame, a chassis, an interior flat bottom floor and a vehicle body, the bottom frame comprises a plurality of hollow rectangular tube frames with through battery boxes, a front frame and a rear frame, the battery boxes are positioned in the middle of the bottom frame, sufficient space is provided for arrangement of a control system, a cooling system and the like at the rear end of the vehicle, the capacity of the batteries is ensured, interior space is increased by the design of the interior flat bottom floor, the number of steps for passengers to get on or off the vehicle is decreased, walking of the passengers is facilitated, and the vehicle can contain more passengers.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and in particular relates to a through-type battery compartment and a vehicle with the battery compartment. Background technique [0002] With the development of the social economy and the improvement of the level of science and technology, as well as the strengthening of people's awareness of environmental protection and the improvement of the quality of life requirements, new energy vehicles have become the focus of people's attention. With the country's strong support for new energy vehicles in recent years, my country's new energy vehicles have developed rapidly and have leaped to the first place in the world in terms of total output; however, there is still a certain gap with foreign countries in terms of key cutting-edge technologies. The world's advanced technology is the only way to change from a big automobile country to a powerful automobile country. [0003] New energy vehicles refer ...

Problems solved by technology

According to the prior art, the battery compartments for loading the battery box are generally distributed on the rear and both sides of the car, but there is no enough space for the rear and both sides of the car when the battery box is sufficiently large. In order to solve this problem, the control system, auxiliary power system, cooling system and other devices have to reduce the interior space of the car; the battery compartment is placed in the rear part of the car and piled up with various system devices, which makes the heat dissipation effect not very good. And it is not very convenient to replace the battery; in the prior art, due to the structure and position of the battery compartment, when replacing the battery box, it is wasteful to drag or push the battery box out, and long-term friction will damage the battery compartment And the structure of the battery box affects the function of the battery and the protection effect of the battery compartment on the battery box

[0005] In the prior art, the space of the flat floor of a passenger car or a bus is small, and generally a convex hull for placing a drive system, a cooling system, etc. is provided at the front end of the flat floor, and the flat floor is provided with a wheel bag at the corresponding wheel. These designs make the interior of the car The flat space of the flat floor is greatly reduced. In order to avoid the impact, there are often seats on the wheel bag to reduce the waste of space, but it is not convenient for passengers to place their legs and feet.

Nowadays, there have been flat bottom plates with no convex hull at the front end, and a large number of devices such as batteries, power systems, auxiliary systems, and cooling systems are installed at the rear of the vehicle. Although the space at the front end of the car is increased, the rear end of the vehicle is concentrated. A large number of devices also reduce the space in the car. Although multi-level steps are set to meet the space for arranging various systems, this also greatly reduces the rear end space of the flat floor in the car, and it is not convenient for passengers to walk.
