As shown in connection with fig. 1-2, a battery holder is provided according to an embodiment of the present application.

The battery support includes: the support body 1, the support body 1 is connected with the battery box; the guide rail 2 is at least one, the guide rail 2 extends along the length direction of the support body 1, the bottom end of the guide rail 2 is connected with the support body 1, and the top end of the guide rail 2 extends along the direction away from the support body 1; wherein, the inside cooperation chamber structure 3 that forms of guide rail 2, cooperation chamber structure 3 form the opening on the top, and guide rail 2 is connected with electric core assembly detachably, and when guide rail 2 was connected with electric core assembly, the installation tooth structure of electric core assembly extended to in the cooperation chamber structure 3 through the opening.

Because the integrated installation is carried out without bonding the modules, the defect that the bonding part is possibly loosened is avoided, and the safety of the battery is improved. By adopting the technical scheme of the application, the problem that the installation and disassembly efficiency of the battery cell assembly is low due to the fact that the connection form between the battery cell assembly and the battery box body is complex in the prior art is effectively solved. The battery support is simple in design, can improve the safety of a power battery, and has higher assembly property and reliability. The battery holder can be applied to battery packs for all-electric vehicles and battery packs for hybrid vehicles.

The mounting tooth structure of the battery cell assembly extends into the matching cavity structure 3 through the opening, and means that the mounting tooth structure is located in the matching cavity structure 3, and in fact, the mounting tooth structure and the matching cavity structure 3 form a mortise-tenon-like structure, namely, the mounting tooth structure protrudes and enters the concave inner part of the matching cavity structure 3. The fact that the mounting tooth structure extends through the opening to the mating cavity structure 3 does not mean that the mounting tooth structure fits into the mating cavity structure 3 through the opening, the fitting steps of both are as follows: as shown in fig. 2, which is a schematic cross-sectional view of the mating cavity structure 3, the mounting tooth structure slides laterally from one of the ends of the guide rail in the length direction into the mating cavity structure 3, and meanwhile, the mounting tooth structure can be moved to a preset position (such as the middle part) in the guide rail by pushing and pulling the electric core assembly, at this time, part of the mounting tooth structure is located in the mating cavity structure 3, the other part of the mounting tooth structure is located outside the mating cavity structure 3, and the boundary part of the two parts is located at the opening.

Further, the cross section of the mating cavity structure 3 along the first direction is one of regular polygon, round and special-shaped, and the cross section is adapted to the outer contour of the mounting tooth structure. The cross-sectional shape of the mating cavity structure 3 in the first direction, i.e. the mating profile of the structure, may be triangular, rectangular, square or profiled. The special-shaped specific form can be obtained by carrying out simulation optimization design by taking modal frequency or noise as an evaluation target. The mating teeth may be arranged vertically or laterally.

As shown in fig. 1, two guide rails 2 are oppositely arranged, the two guide rails 2 are respectively positioned at two sides of the support body 1 along the width direction, the two guide rails 2 are matched and connected with corresponding mounting tooth structures, and a mounting space for accommodating the battery cell body of the battery cell assembly is formed between the two guide rails 2.

Preferably, the battery support is bolted to the bottom of the case, or is fixed to the bottom of the case by welding, riveting, or the like.

It should be noted that the support body 1 may be connected to the bottom wall of the case, and may also be connected to the inner side wall of the case. Correspondingly, the mounting tooth structure is also required to be correspondingly arranged on the side wall of the battery cell assembly.

That is, the guide rail 2 may be an integral type or a split type, and if the guide rail 2 is split type, different sections of the guide rail 2 are correspondingly provided with different battery cell assemblies.

Specifically, the top end surface of the guide rail 2 is higher than the top surface of the support body 1, so that the side wall of the guide rail 2 can be used for limiting the battery cell assembly, and the connection stability of the battery cell assembly is improved. When the guide rails 2 are arranged into a multi-section structure, the axes of the extending arrangement of the guide rails 2 of each section are arranged in a non-overlapping mode, namely, the guide rails 2 of each section are arranged in a staggered mode, and therefore the battery support can be used for adaptively mounting battery cores of different sizes. In another alternative embodiment, the guide rail 2 is provided in the form of an upper and lower split.

Further, a space is formed between two adjacent guide rails 2, and a battery accessory is arranged in the space, wherein the battery accessory at least comprises at least one of a heat conducting frame, a heat insulating plate and a liquid cooling plate. The arrangement can fully utilize the space in the battery pack, and further improve the energy storage density of the battery pack.

In an alternative embodiment, the cell assembly has a connection structure protruding from the outer wall surface, and the battery support is provided with an upper split portion and a lower split portion along the height direction, and is clamped and locked up by the upper split portion and the lower split portion, wherein the connection structure includes, but is not limited to, a protruding metal sheet, a rod-shaped member or a columnar structure. By adopting the scheme, the connection stability of the battery cell assembly and the battery support can be improved, and meanwhile, the assembly in the production process is convenient.

Alternatively, the holder body 1 is provided integrally with the guide rail 2. The arrangement improves the manufacturability of the two and reduces the production cost.

Further, the support body 1 is provided with a bolt hole 4, and the support body 1 is detachably connected with the battery box body through the bolt hole 4, or the support body 1 is fixed with the battery box body through welding. This arrangement enhances the stability of the connection of the holder body 1. The mounting seat is arranged at the bottom of the battery box body through the bolt hole 4 and can also be welded at the bottom of the box body. Only 3 are shown in fig. 1, and the number of bolt holes may be one, two or more. The number of the bolt holes can be adjusted according to requirements.

The arrangement can prevent the working state failure of the battery cell assembly caused by the fact that the battery cell assembly slides out of the guide rail. That is, the holder body 1 is provided at an end thereof with a battery cell movable limit hole.

Further, the bottom side wall of the installation space is arranged flush with the bottom surface of the inner side wall of the matching cavity structure 3. The positioning and the assembly of the tooth structure are convenient to install, and the assembly efficiency of the tooth structure and the tooth structure is improved.

As an alternative embodiment, the battery cell may be adhered to the case, but has the disadvantages of complex disassembly and poor installation stability. The battery cell is connected to the box body through the bolts after being packed into the module, but the problems of numerous parts and complex structure exist, and the disassembly steps are complex and complicated.
