[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] See Figures 1-10 This utility model embodiment provides an anti-displacement device for a battery pack in an energy storage box, used to limit and fix the battery pack. The device includes a limiting plate 1 and a pressure plate 3. The limiting plate 1 is installed on the mounting bracket 04 of the battery cabinet 03. The limiting plate 1 has a U-shaped structure. Multiple pairs of L-shaped openings 2 are opened on the two side walls of the limiting plate 1. The pressure plate 3 has a U-shaped structure that matches the inner wall of the U-shaped structure. Multiple pairs of claws 4 extend horizontally outward from the two side walls of the pressure plate 3. The claws 4 slide and engage in the L-shaped openings 2.

[0029] The energy storage box battery pack anti-displacement devices provided in this embodiment are used in pairs, with the two devices having a mirror-like structure. The limiting plate 1 is a long, rectangular square tube with openings at both ends and the top surface, and a U-shaped cross-section. The bottom surface of the limiting plate 1 is welded and fixed to the mounting bracket 04, or the limiting plate 1 and the mounting bracket 04 are integrally formed. The pressure plate 3 is a long, rectangular square tube with an open bottom surface, and a U-shaped cross-section. The width of the pressure plate 3 is smaller than the width of the limiting plate 1, allowing the pressure plate 3 to fall into the limiting plate 1.

[0030] In this embodiment of the utility model, the L-shaped opening 2 on the limiting plate 1 is provided with six pairs, and correspondingly, the claws 4 provided on the pressure plate 3 are provided with six pairs. When the pressure plate 3 falls into the limiting plate 1, the claws 4 on both sides of the pressure plate 3 fall into the vertical part of the L-shaped opening 2 until they are against the bottom surface. Then, the pressure plate 3 moves along its own length direction to make the claws 4 slide into the horizontal part of the L-shaped opening 2, so as to realize the sliding engagement of the claws 4 and the L-shaped opening 2.

[0031] The dimensions of the limiting plate 1, the L-shaped opening 2, the pressure plate 3, and the claw 4 are designed such that the distance between the bottom surface of the claw 4 and the top surface of the mounting bracket 04 matches the thickness of the connecting part 02 that extends horizontally outward from the outer shell of the battery pack 01. This ensures that after the battery pack 01 is placed on the mounting bracket 04 and fixed with bolts, when the claw 4 slides into the L-shaped opening 2, the bottom surface of the claw 4 is in contact with the top of the connecting part 02, and the claw 4 has no vertical movement space within the L-shaped opening 2. In this way, the limiting plate 1 and the pressure plate 3 limit the battery pack 01 vertically, and the bolts on the mounting bracket 04 limit the battery pack 01 horizontally, thus achieving a more stable limitation of the battery pack 01.

[0032] In addition, to ensure the effective fixation of the battery pack 01 on both sides, at least one pair of L-shaped openings 2 are provided at each end of the limiting plate 1, and at least one pair of claws 4 are provided at each end of the pressure plate 3. In this embodiment of the present invention, two pairs of the six pairs of L-shaped openings 2 are provided near the ends of the limiting plate 1, and correspondingly, two pairs of the six pairs of claws 4 are provided near the ends of the pressure plate 3.

[0033] In one embodiment of the present invention, a baffle 5 is connected to the front end of the limiting plate 1, and the front end of the baffle 5 is inclined away from the battery pack 01.

[0034] When the energy storage box is assembled in the factory, the battery pack 01 is delivered to the front of the battery cabinet 03 by a forklift and then placed on the mounting rack 04. The baffles 5 on the mounting racks 04 on both sides can help guide the battery pack 01 into the designated position on the mounting rack 04.

[0035] The tail end of the limiting plate 1 bends toward the battery pack 01 to form a limiting part 8, which facilitates limiting the depth of the battery pack 01 into the battery cabinet 01 when the battery pack 01 is delivered to the mounting frame 04 by a forklift.

[0036] In order to prevent the pressure plate 3 from slipping, in one embodiment of the present invention, the front end of the pressure plate 3 is bent inward towards the limiting plate 1 and a first limiting hole 6 is provided in the bent part, and a second limiting hole 7 is provided at the bottom of the limiting plate 1. The first limiting hole 6 and the second limiting hole 7 are aligned when the claw 4 slides and engages in the L-shaped opening 2.

[0037] When the first limiting hole 6 and the second limiting hole 7 at the front end of the pressure plate 3 coincide, a pin is inserted to limit the pressure plate 3 relative to the limiting plate 1 in the length direction of the pressure plate 3, thereby improving the snap-fit ​​stability between the pressure plate 3 and the limiting plate 1.

[0038] To facilitate the assembly of the pressure plate 3 and the limiting plate 1, the L-shaped opening 2 has a rounded corner structure at the L-shaped corner, making it easier for the claws 4 on the pressure plate 3 to slide and engage into the horizontal part of the L-shaped opening 2.

[0039] In an optional embodiment of this utility model, a handle 9 is connected to the top of the pressure plate 3. The handle 9 is a hollow round tube with both ends welded to the top surface of the pressure plate 3. The pressure plate 3 can be placed into the limiting plate 1 by holding the handle 9, so that the claw 4 falls into the bottom of the vertical part of the L-shaped opening 2. Then, the pressure plate 3 is pulled horizontally outward from the battery cabinet 03 by holding the handle 9, so as to realize the sliding engagement of the claw 4 with the L-shaped opening 2, thereby improving the ease of operation.

[0040] In summary, the energy storage box battery pack anti-displacement device provided in this embodiment of the present invention is used by welding a pair of mirror-image energy storage box battery pack anti-displacement devices onto the mounting frame 04. The battery pack 01 is transported to the front of the battery cabinet 03 by a forklift, and then into the battery cabinet 03 until it reaches the top of the mounting frame 04. During this process, the baffle 5 at the front end of the limiting plate 1 assists in guiding the battery pack 01 to be aligned and enter the battery cabinet 01. The forklift arm moves down to place the battery pack 01 on the mounting frames 04 on both sides and align it with the mounting holes on the mounting frame 04. Bolts are then inserted into the mounting holes. Then, the claws 4 of the pressure plate 3 are placed into the L-shaped opening 2 of the limiting plate 1, so that the claws 4 slide and engage with the horizontal part of the L-shaped opening 2. At the same time, the first limiting hole 6 at the front end of the pressure plate 3 is aligned with the second limiting hole 7 on the limiting plate 1. Pins are inserted into the first limiting hole 6 and the second limiting hole 7, thus completing the limiting and fixing of the battery pack 01 by the energy storage box battery pack anti-displacement device.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
