[0043] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0044] like Figures 1-5 As shown, a container battery pack with a stepped limiting device according to this utility model includes a bracket 2 and a battery pack 1 fixed on the bracket 2. A Z-direction limiting structure is provided between the battery pack 1 and the bracket 2 for Z-direction limiting after the battery pack 1 is installed.

[0045] The Z-direction limiting structure includes limiting posts 11 and baffles 21. Several limiting posts 11 are provided on the side of the battery pack 1, and the limiting posts 11 are arranged at intervals along the X-direction with decreasing heights, forming a stepped arrangement. At the same time, a baffle 21 is provided on the top of each limiting post 11. The baffle 21 and the limiting post 11 cooperate to form the Z-direction limiting structure. The baffle 21 is set on the bracket 2, and a 2mm gap is reserved between its top and the corresponding limiting post 11.

[0046] After the battery pack 1 is installed, it is supported by the limit stake 11 and the baffle 21 to achieve the Z-direction limit of the battery pack 1. After the limit is achieved, the vibration resistance and stability of the battery pack 1 can be improved, ensuring its safety and reliability during transportation and use, so that it can be used in large-capacity energy storage systems.

[0047] In the above structure, the battery pack 1 includes a cover 12 and a body 13, wherein the cover 12 is disposed on the body 13, the body 13 is disposed on the bracket 2, and the limiting post 11 is disposed on the body 13.

[0048] Specifically, a U-shaped opening 1201 is provided on the cover 12 at the position corresponding to the limiting post 11. The limiting post 11 passes through the U-shaped opening 1201 vertically, so the limiting post 11 does not contact the cover 12. At the same time, the limiting post 11 is welded to the housing 13. When limiting, the Z-direction force does not need to be transmitted through the cover 12, rivet nuts, sealing rings, etc., but acts directly on the housing 13. It has high strength and does not affect the sealing of the cover 12 or the torque of the locking bolt of the cover 12, which is beneficial to the protection of the battery pack 1.

[0049] In the above structure, limit posts 11 are provided on both sides of the housing 13. Correspondingly, two rows of baffles 21 are also provided on the bracket 2, so that both sides of the battery pack 1 can be limited in the Z direction, thereby improving the vibration resistance and stability of the battery pack 1.

[0050] In the above structure, the support 2 includes a column 22 and a bracket 23. The column 22 is welded into a frame structure by tubing. At least one bracket 23 is installed on the column 22 in a vertical direction to support the battery pack 1. A baffle 21 is installed on the bracket 23 and is located on the side of the battery pack 1.

[0051] Specifically, bracket 23 consists of two angle irons, one of which is supported on the bottom of one side of battery pack 1 and the other is supported on the bottom of the other side of battery pack 1. Bolts are screwed to the bottom of the angle irons, and the upper end of the bolts is screwed to the bottom of battery pack 1 to fix battery pack 1 to bracket 2.

[0052] The baffle 21 includes a vertical portion 2101, a horizontal portion 2102, and a guide portion 2103. The vertical portion 2101 is mounted on the bracket 23. The horizontal portion 2102 is located at the top of the vertical portion 2101. The guide portion 2103 is located on the side of the horizontal portion 2102, and the end of the guide portion 2103 away from the horizontal portion 2102 is bent upward in a skid shape.

[0053] Specifically, the vertical part 2101, the horizontal part 2102 and the guide part 2103 are integrally formed by sheet metal, and the formed baffle 21 is welded and fixed on the bracket 23.

[0054] like Figure 4 As shown, the arrow points in the X-axis direction, which is the direction in which battery pack 1 is pushed. That is, when installing battery pack 1, it is pushed into bracket 23 along the X-axis direction. During the pushing process, the guide part 2103 guides the limiting post 11 smoothly into the bottom of the horizontal part 2102. For this purpose, the guide part 2103 is set on the end of the horizontal part 2102 facing the pushing direction of battery pack 1. At the same time, the height of the baffles 21 is adapted to the height of the limiting posts 11, that is, the baffles 21 are also arranged at intervals along the X-axis and the height decreases, forming a stepped arrangement.

[0055] In the above structure, the bottom of the limiting post 11 is provided with a pin 1101, and the upper edge of the box 13 is provided with a pin hole 1301. The pin 1101 is embedded in the pin hole 1301 to improve the firmness of the connection between the limiting post 11 and the box 13.

[0056] The limiting post 11 is set as a rubber post or a metal post. When it is a rubber post, the limiting post 11 is glued and fixed to the box body 13. When it is a metal post, the limiting post 11 is welded and fixed to the box body 13.

[0057] The following is a method of using a container battery pack with a stepped limiting device according to this utility model:

[0058] Press battery pack 1 Figure 4The pushing direction shown pushes the bracket 23, after being in place, the limiting stake 11 and the baffle 21 are matched up and down to realize Z-direction limiting of the battery pack 1, then the battery pack 1 is fixed on the bracket 23 through bolts, finally the installation and fixation of the battery pack 1 are realized.

[0059] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
