[0025] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0026] Example 1

[0027] refer to Figure 1-3 , an energy storage battery module rack provided with a grounding mechanism, comprising:

[0028] The box body 1 is composed of three sides of the enclosure connected in sequence and two upper and lower bottom plates, and the front side of the box body 1 is provided with an opening;

[0029] A plurality of support mechanisms are arranged and installed in the box body 1 at intervals up and down and are used to support and install the battery module 2. The support mechanism includes a group of support plates 3 that are symmetrically arranged and fixedly installed on the two side panels respectively. The rear side of the installation side plate of the battery module 2 is fixedly provided with a grounding crimping bearing portion 4 that is electrically connected to the battery module 2, and the front side thereof is fixedly connected with a wedge-shaped member 5 whose outer side surface is in the shape of an inclined surface, and the grounding crimping bearing portion 4 is located on the inner side of the wedge-shaped member 5;

[0030] A grounding mechanism is correspondingly installed on the support plate 3, and is used for limiting and fixing the battery module 2 and electrically connecting the battery module 2 to the outside. The grounding mechanism includes a limiting plate 6 swingably installed in the middle of the support plate 3. The middle part of the limiting plate 6 is hinged to the support plate 3, and its two ends are bent outward and protruded. The rear end of the limiting plate 6 is installed with a corresponding grounding crimping portion 7; when the battery module 2 is installed, its installation side plate pushes the front end of the limiting plate 6 to swing inward and the rear end to swing outward, so that the grounding crimping portion 7 abuts against the grounding crimping bearing portion 4.

[0031] The utility model can improve the convenience and stability of assembling the battery module 2 on the basis of ensuring smooth installation of the battery module 2, and can also realize the rapid connection and rapid grounding installation of the battery module 2, effectively solving the disadvantages of the traditional rack and improving the practical performance.

[0032] The grounding crimping portion 7 is electrically connected to the outside through a limiting plate 6 having metallic conductivity, and the battery module 2 is electrically connected to the outside through the connection between the grounding crimping portion 7 and the grounding crimping bearing portion 4 .

[0033] The limiting plate 6 is an L-shaped structure in longitudinal section composed of an integrally formed longitudinal vertical plate and a transverse bottom plate. The middle part of the longitudinal vertical plate is recessed inwardly and provided with a corresponding notch groove. The limiting plate 6 is rotatably installed in the notch groove, and its front and rear ends are arranged on the outside of the notch groove.

[0034] A supporting elastic member 8 with conductive properties is connected and installed between the rear end portion of the limiting plate 6. When the battery module 2 is installed, the supporting elastic member 8 is set in a stretched state. The initial positioning of the limiting plate 6 can be achieved through the supporting elastic member 8, and the restoring of the limiting plate 6 is promoted when the battery module 2 is pulled out.

[0035] The front end of the limiting plate 6 is bent outward and the rear end thereof is configured to be spherical and matched with the wedge-shaped member 5 , and the inclined surface of the wedge-shaped member 5 is configured to be gradually inclined downward from front to back.

[0036] The utility model proposes a grounding mechanism of a new structure, which includes a limiting plate 6 swingably mounted on a box body 1, and a grounding crimping portion 7 mounted on the limiting plate 6, and a grounding crimping bearing portion 4 is fixedly mounted on a mounting side plate of a battery module 2; during the installation of the battery module 2, the mounting side plate of the battery module 2 pushes the front end of the limiting plate 6 to swing inward and the rear end to swing outward, so that the grounding crimping portion 7 is connected to the grounding crimping bearing portion 4, and the two ends of the limiting plate 6 are respectively crimped with the mounting side plate of the battery module 2, thereby improving the convenience and stability of assembly of the battery module 2 and realizing the rapid connection of the battery module 2 and the rapid operation of grounding installation.

[0037] Furthermore, the swing installation of the limit plate 6 is realized by a hinged manner, and the bufferable compression installation of the grounding crimping part 7 is realized by a supporting elastic part 8 with conductive properties, so as to ensure the assembly stability; furthermore, a wedge-shaped part is arranged on the side plate of the battery module 2 for mounting the side plate, and the wedge-shaped part is utilized to drive the rear side of the limit plate 6 to swing outward, so that the front end of the limit plate 6 swings inward, so that the grounding crimping part 7 is connected to the grounding crimping bearing part 4 as the limit plate 6 swings inward.

[0038] Example 2

[0039] The difference from Example 1 is that the limiting plate 6 is an elastic metal plate with conductive properties. When the battery module 2 is installed, its installation side plate pushes the front end of the limiting plate 6 to swing inward and the rear end to swing outward, so that the grounding crimping portion 7 abuts against the grounding crimping bearing portion 4, and the front and rear ends of the limiting plate 6 are both arranged in an inward pushing shape.

[0040] The limiting plate 6 of the utility model can be an elastic metal plate with conductive properties. The adaptability of the elastic metal plate is used to ensure that the grounding crimping part 7 and the grounding crimping bearing part 4 are pressed and electrically connected to ensure the connection stability. In addition, its elastic effect promotes the resetting of the limiting plate 6 when the battery module 2 is pulled out.

[0041] Example 3

[0042] The difference from Example 1 lies in that: a plurality of positioning rods 9 are fixedly welded at intervals up and down on the enclosure of the support plate 3 of the box body 1, and the longitudinal section of the positioning rod 9 is circular, trapezoidal or rectangular, and the outer wall of the support plate 3 is recessed inward from top to bottom and is provided with a plurality of embedding grooves 601 adapted to the positioning rod 9, and the support plate 3 can be detachably mounted on the enclosure by correspondingly inserting the positioning rod 9 into the embedding grooves 601, and the outer end portion of the positioning rod 9 is locked and fixed with a corresponding bolt, and the head diameter of the bolt is larger than the width of the embedding groove 601.

[0043] By interlacing the positioning rod 9 and the embedding groove 601 to cooperate with the detachable installation plate 3, and locking and fixing it with a bolt whose head diameter is larger than the width of the embedding groove 601, the support plate 3 can be easily disassembled and replaced, thereby improving its ease of use, and the spacing between the support plates 3 can be flexibly adjusted to adapt to the installation of battery modules 2 of different heights, thereby improving the scope of application.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
