Description

Technical Field

[0001] The utility model belongs to the technical field of battery boxes, and particularly relates to a spliced ​​flameproof battery box with an internal injection molded part structure for reducing battery collision. Background Art

[0002] The internal injection molded parts of the spliced ​​flameproof battery box refer to a component used in electric vehicles or energy storage systems, usually made by an injection molding process. The component uses injection molding technology to inject materials directly into the mold to form a specific shape and structure. It is used to fix and isolate battery modules, battery cells or other battery components. These injection molded parts are usually responsible for fixing battery components, protecting batteries, isolating heat and providing structural strength, thereby ensuring safe and reliable operation of the battery.

[0003] The injection molded parts in some existing spliced ​​flameproof battery boxes have defects and are not equipped with sufficient locking and shock-absorbing structures. After the batteries have been used in the spliced ​​flameproof battery box for a period of time, the vibration and vibration of the batteries may cause the structure to loosen. There is a gap between the batteries and the injection molded parts, and the subsequent batteries are prone to collision with the injection molded parts. In the long run, it is easy to affect the safety and stability of the internal components of the battery box, and also reduce the service life of the battery itself. Therefore, we hope to design an internal injection molded parts structure of a spliced ​​flameproof battery box with a new structure to solve this problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a spliced ​​flameproof battery box with an internal injection molded structure to reduce battery collisions, thereby solving the problems raised in the above-mentioned background technology.

[0005] The utility model is realized by the following technical scheme: a spliced ​​flameproof battery box with an internal injection molding structure to reduce battery collision, comprising: a flameproof box body, a flameproof box plate, and a battery accommodating box, wherein a flameproof box plate is movably inserted at the front and rear sides of the flameproof box body, and a plurality of battery accommodating boxes are movably inserted inside the flameproof box body;

[0007] A plurality of vertical shock-absorbing partitions are integrally injection-molded inside the box body, and a plurality of limiting members are movably installed on the upper side of the inside of the box body through the vertical shock-absorbing partitions and the horizontal shock-absorbing partitions.

[0008] As a preferred embodiment, the front and rear sides of the explosion-proof box body are both designed to be open, and a slot is respectively provided on the left side and rear side of the front end and the left side and rear side of the explosion-proof box body from top to bottom.

By setting a reserved notch on the front and rear sides of the box, when the battery inside the box generates heat during operation, the heat can reach the air vent group on the explosion-proof box through the reserved notch, thereby quickly dissipating the heat.

[0011] As a preferred embodiment, the front and rear sides of the transverse shock-absorbing partition are respectively recessed inward to form a plurality of embedding grooves 1, and a shock-absorbing side panel 3 is glued into each of the embedding grooves 1, and the thickness of the shock-absorbing side panel 3 is twice the depth of the embedding groove 1.

[0012] As a preferred embodiment, a plurality of fixing holes are downwardly opened on the upper end of each of the vertical shock-absorbing partitions, and the left inner wall and the right inner wall of each of the vertical shock-absorbing partitions are recessed inward to form an embedded groove 2, and a shock-absorbing side panel 2 is glued in each of the embedded grooves 2, and the thickness of the shock-absorbing side panel 2 is twice the depth of the embedded groove 2.

A cantilever plate is integrally provided on the left and right sides of each mounting portion, and a plurality of linearly distributed elastic connecting blocks are fixed to the lower side of each cantilever plate. A shock-absorbing top plate is fixed to the lower side of each cantilever plate through a plurality of elastic connecting blocks. By arranging a shock-absorbing side plate one, a shock-absorbing side plate two, a shock-absorbing side plate three, a shock-absorbing bottom plate and a shock-absorbing top plate, the collision between the battery and the box, the horizontal shock-absorbing partition and the vertical shock-absorbing partition can be reduced.

[0014] As a preferred embodiment, the number of the mounting parts is the same as the vertical direction of the vertical shock-absorbing partition, and the mounting parts are fixed to the upper end of the vertical shock-absorbing partition through screws and fixing holes, and the height of the top of the cantilever plate is smaller than the height of the upper end of the box body.

[0015] After adopting the above technical solution, the utility model has the beneficial effects of: by providing a flameproof box body and cooperating with a detachable flameproof box plate, the heat generated by the battery during normal operation and the electric sparks and high temperature generated during a fault are confined in the battery container, thereby achieving a flameproof effect;

[0016] By setting the horizontal shock-absorbing partition and the vertical shock-absorbing partition, in conjunction with the box body, in actual use, the shock-absorbing side panel 1, the shock-absorbing side panel 2, the shock-absorbing side panel 3, the shock-absorbing bottom panel and the shock-absorbing top panel are all made of elastic material panels (flame-retardant rubber material can be selected, and the specific type of flame-retardant rubber can be selected according to actual use requirements). By setting the shock-absorbing side panel 1, the shock-absorbing side panel 2, the shock-absorbing side panel 3, the shock-absorbing bottom panel and the shock-absorbing top panel, the upper side, lower side, left side, right side, top and bottom of the battery can be surrounded (see the attached manual for details). Figure 3 The vertical shock-absorbing partition and the horizontal shock-absorbing partition divide the space inside the box into multiple cavities, each of which can be installed with a battery, and at the same time, the four sides, a bottom and a top of each cavity are surrounded by flame-retardant material panels). During installation, after the battery is placed in the corresponding installation space, the limiter is fixed on the vertical shock-absorbing partition, and the shock-absorbing top plate on the lower side is used to press the top of the battery. This allows the battery to be tightly abutted against the shock-absorbing side panel one, the shock-absorbing side panel two, the shock-absorbing side panel three, the shock-absorbing bottom plate and the shock-absorbing top plate after installation. The shock-absorbing side panel one, the shock-absorbing side panel two, the shock-absorbing side panel three, the shock-absorbing bottom plate and the shock-absorbing top plate produce a certain elastic deformation, thereby clamping the battery to ensure that the battery will not loosen due to vibration during subsequent use. Not only can the battery be shock-absorbing to a certain extent, but it can also protect the battery and reduce the collision between the battery and the box, the horizontal shock-absorbing partition and the vertical shock-absorbing partition.
