Embodiment 1

[0023] like figure 1 The battery box shown is used to be installed at the bottom of the car, and includes a box cover 1 , a box body 2 , a connecting body 5 and a battery pool system 3 . The connecting body 5 is equipped with bolts (not shown in the figure), which are used to connect the battery box with the vehicle body. The bottom of the battery box is made of a hollow clamping wall structure composed of an inner wall 7 and an outer wall 8. The inner wall 7 is fixed and sealed with the box body 2 through a fixed body 12, and the battery box is divided into a box space 16 And two parts of the interwall space 10. The battery system 3 is installed on the inner wall 7 in the box space 16 . The box space 16 is not in communication with the sandwiched wall space 10 .

[0024] The connecting body 5 is located at a position corresponding to the boundary between the box space 16 and the clamping wall space 10, so that after the battery box is connected to the vehicle body through ...

Embodiment 2

[0030] like figure 2 The shown battery box is used to be mounted on the back of the car, and its difference from Embodiment 1 is that the bottom of the battery box and the back wall are both made of a hollow clamping wall structure composed of an inner wall 7 and an outer wall 8 . That is, the battery box includes two interwall spaces. After the battery box is connected with the vehicle body through the connecting body 5, except the bottom of the box, the wall surface at the back of the box is also exposed outside the vehicle body. The inner walls 7 of the two clamping walls are heat conduction walls made of metal materials. The two heat conduction walls are equipped with a metal heat dissipation plate 9 on one side of the interwall space. On the folder wall at the bottom of the battery box, there is an air intake hole in the direction of the car (the direction indicated by the arrow in the figure), that is, the ventilation hole 11 on the left side below the figure. On the...

Embodiment 3

[0033] like image 3The difference between the shown battery box and Embodiment 1 is that each wall of the battery box is a hollow clamping wall structure. Wherein the clamping wall at the bottom of the battery box is provided with a ventilation hole 11 to form a ventilation channel 10 . All the other walls are sealed and separated by the fixed body 12, so that they are not connected with the outside world, nor communicated with the air passage at the bottom. The fixed body 12 is made of a bolt damping connection part with a plastic sleeve, a spring and a rubber pad, and has the functions of buffering and heat insulation. The inner wall 7 of the battery box and the cooling fins 9 at the bottom are made of aluminum alloy, and the outer wall 8 is made of engineering plastics to reduce the weight of the whole box. Obviously, when the ventilation door 6 is closed, each clamping wall of the battery box in this example has the function of a heat insulating wall. And when the vent...

Abstract

The invention provides a multifunctional vehicle-borne battery box, which comprises a box cover, a box body, connecting bodies and a battery system. The multifunctional vehicle-borne battery box is characterized in that: at least one wall of the battery box is a hollow double-walled structure composed of an inner wall and an outer wall. The inner wall is a heat conduction wall, and is in fixed and sealing connection with the box body through fixation bodies, so that the battery box is divided into a box body space and a double-walled space that are not communicated mutually. The double-walled space is provided with ventilation holes that are equipped with ventilation doors. And the double-walled space can be communicated with the outside through the ventilation doors. The multifunctional vehicle-borne battery box provided in the invention can satisfy the heat preservation, waterproofness, shock resistance, impact resistance, heat dissipation and other technological requirements needed by an electric vehicle battery box, so that the reliability and service life of a battery system can be improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a design of a battery box of the electric vehicle. Background technique [0002] With the improvement of people's requirements for environmental protection, the research and application of electric vehicles have been paid more and more attention. Since the current single battery cannot meet the power requirements of electric vehicles, the power of electric vehicles is provided by a battery box with multiple batteries. In order to ensure that the electric vehicle can work safely and normally in various environments, the battery box usually needs to have the functions of waterproof, shockproof, impact resistance, heat dissipation and heat preservation. Obviously, there is a contradiction between these functional requirements, thus bringing challenges to the design of the battery box. Contents of the invention [0003] In order to meet the above-mentioned technical requirements ...
