Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, the present embodiment provides a lithium battery case structure, which includes a lithium battery case 1 and a metal top plate 2, wherein the metal top plate 2 is mounted on the top of the lithium battery case 1;
the bottom of the lithium battery box body 1 is sleeved with a protective bottom plate 3, and the protective bottom plate 3 is made of metal. A buffer soft rubber block 4 is padded between the bottom of the lithium battery box body 1 and the protective bottom plate 3; the thickness of one side of the buffer soft rubber block 4 is 3-4mm. The buffer soft rubber block 4 is of a hollow structure, and the hollow structure is filled with liquid.
The bottom of the lithium battery box body 1 is provided with a pressure relief groove; the pressure release grooves are positioned on two sides of the bottom of the lithium battery box 1 as shown in fig. 2. The number of the pressure relief grooves is two, and the two pressure relief grooves are respectively positioned on two side walls of the lithium battery box body 1.
A plurality of telescopic rods 5 are arranged on the metal top plate 2, the telescopic rods 5 are straight rods which slide and stretch in a sleeve, and the straight rods are output ends of the telescopic rods 5 and can also be elastic telescopic rods in the prior art. The output end of the telescopic rod 5 is connected with the protective bottom plate 3. When the telescopic rod 5 is in the limit stroke, the protective bottom plate 3 is sleeved at the bottom of the lithium battery box body 1, and the buffer soft rubber block 4 is in an uncompressed state
The buffer soft rubber block 4 is connected with two expansion soft rubber blocks 6 communicated with the inside of the buffer soft rubber block 4, and the thickness of one side of each expansion soft rubber block 6 is 3-4mm. The two expansion soft rubber blocks 6 are respectively inserted into the two pressure relief grooves.
Expansion boxes 7 are arranged on two sides of the lithium battery box body 1, and expansion ports which are communicated with the pressure relief grooves and the expansion boxes 7 are formed on two sides of the lithium battery box body 1. The expansion box 7 can also play a certain role in protecting the internal expansion soft rubber block 6, and the expansion soft rubber block 6 is prevented from being extruded, worn and broken when contacting with external muddy water and the like. When the protective bottom plate 3 is hit by the above-ground stone or sharp points, the protective bottom plate 3 extrudes the buffer soft rubber block 4, liquid in the buffer soft rubber block 4 is extruded into the expansion soft rubber blocks 6 at the two sides, the liquid in the expansion soft rubber blocks 6 is increased and expanded, and the expanded expansion soft rubber blocks 6 enter the space in the expansion box 7 to release pressure.
The bottom surface of metal roof 2 installs liquid cooling board 8, and liquid cooling board 8 can cover the open-top of lithium cell box 1. The lithium battery pack in the lithium battery case 1 is cooled by the liquid cooling plate 8.
In the actual use process, when the vehicle runs on uneven ground or raised ground with stones and the like, and then the protective bottom plate 3 collides with the protrusions, the protective bottom plate 3 moves upwards to squeeze the buffer soft rubber block 4, the buffer soft rubber block 4 plays a role in buffering the protective bottom plate 3, and the occurrence of local deformation of the protective bottom plate 3 caused by collision is reduced; in addition, when the protective bottom plate 3 extrudes the buffer soft rubber block 4, liquid in the buffer soft rubber block 4 is extruded into the expansion soft rubber block 6, the liquid in the expansion soft rubber block 6 is increased and expanded, and the expanded expansion soft rubber block 6 enters a space in the expansion box 7 for pressure relief. So that the buffer stroke of the shield floor 3 becomes long. (for example, if the basketball is played by a ball, the palm can collide with the basketball if the basketball is directly hard-connected by the hand, so that the palm can feel painful due to the collision, and the hand can move backwards for a certain distance along the movement of the basketball at the moment of contacting the basketball, so that the collision force between the basketball and the palm can be buffered, and the pain is reduced).
