Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1-8 As shown, in a first aspect embodiment of the present invention, a mounting and fastening structure for an energy storage battery pack is provided, comprising a bracket 1 and a fixing component 2, wherein: The bracket 1 has an opening 11 in a direction perpendicular to the vertical direction, and the opening 11 is used for placing and removing the battery pack 100; The fixing assembly 2 includes a rotating shaft 21, a limiting member 22, and a plurality of clamping members 23. The rotating shaft 21 is fixedly installed on the bracket 1. The limiting member 22 is installed on the bracket 1 and can restrict the rotation of the rotating shaft 21. The plurality of clamping members 23 are arranged along the length direction of the rotating shaft 21. The clamping members 23 are fixed on the rotating shaft 21 and rotate together with the rotating shaft 21. The clamping members 23 extend radially along the rotating shaft 21. When the clamping member 23 abuts against and presses against the side 101 of the battery pack 100, the limiting member 22 is limitedly connected to the rotating shaft 21; When it is necessary to remove the battery pack 100, the limiting member 22 and the rotating shaft 21 are released, and the clamping member 23 and the rotating shaft 21 rotate together to the side 101 above the battery pack 100.

[0022] It should be noted that in this embodiment, the battery pack 100 is provided with side edges 101 on both sides. The bottom surface of the side edge 101 is placed on the bracket 1, and the clamping member 23 clamps the top surface of the side edge 101, thereby limiting the battery pack 100 in the Z direction.

[0023] The energy storage battery pack mounting and fastening structure proposed in this embodiment is fixedly mounted on the bracket 1 via the rotating shaft 21. The limiting member 22 is mounted on the bracket 1 and can restrict the rotation of the rotating shaft 21. Multiple clamping members 23 are arranged along the length direction of the rotating shaft 21. When the clamping member 23 abuts and presses against the side 101 of the battery pack 100, the limiting member 22 is connected to the rotating shaft 21 to limit and fix the battery pack 100. When it is necessary to remove the battery pack 100, the limiting member 22 is released from the limiting of the rotating shaft 21, and the clamping member 23 and the rotating shaft 21 rotate together to above the side 101 of the battery pack 100, so that the battery pack 100 can be taken out from the opening 11. While achieving the limiting, it also prevents the battery pack 100 from moving around and facilitates the installation of the battery pack 100.

[0024] In some embodiments, the cross-section of the clamping member 23 is an arc-shaped ring, and the outer wall of the arc-shaped ring is a minor arc. The arc-shaped cross-section of the clamping member 23 allows it to clamp and limit the contact of the battery pack 100 after rotating at a certain angle. The state can be switched by rotating the rotating shaft 21, which is convenient and quick, improving assembly and disassembly efficiency. In this embodiment, the central angle of the clamping member 23 is 90 degrees, which is a quarter arc.

[0025] In some embodiments, the limiting member 22 is a screw, and the rotating shaft 21 is provided with a plurality of limiting holes 211 along the circumferential direction on the same plane. The limiting member 22 is used to insert into one of the plurality of limiting holes 211. With the following structural configuration, after the rotating shaft 21 rotates at a certain angle, the rotating shaft 21 can be limited, so that the rotating shaft 21 is limited to a certain angle, which facilitates the insertion of the battery pack 100 and the limiting and fixing of the battery pack 100.

[0026] In some embodiments, one end of the rotating shaft 21 is provided with a baffle 24, which abuts against the bracket 1 to prevent the rotating shaft 21 from falling off the bracket 1 during rotation, thereby improving reliability. The other end of the rotating shaft 21 is connected to an actuator 25, the actuator 25 having a polygonal cross-section. The polygonal design of the actuator 25 facilitates the rotation of the rotating shaft 21, prevents slippage during rotation, and improves operational convenience and reliability.

[0027] In some embodiments, the actuator 25 is a hexagonal nut, and six limiting holes 211 are provided, evenly distributed circumferentially. This corresponding arrangement ensures that for every 60-degree rotation of the actuator 25, a limiting hole 211 corresponds to the limiting member 22, eliminating the need for alignment and thus improving reliability and stability. Of course, the number of limiting holes 211 can be set as needed, and the rotation angle of the actuator 25 can be adjusted arbitrarily, as long as the limiting holes 211 are aligned with the limiting member 22.

[0028] In some embodiments, the fixing assembly 2 further includes a plurality of buffer pads 26, which are fitted against the surfaces of the clamping members 23 that abut against the side edges 101 of the battery pack 100. Each clamping member 23 has a corresponding buffer pad 26. The buffer pads 26 cushion the space between the battery pack 100 and the clamping members 23, while also allowing for greater compressive force between the two, thus facilitating better fixation of the battery pack 100. The buffer pads 26 can be made of rubber or foam.

[0029] In some embodiments, the fixing component 2 is provided in two sets, and the clamping members 23 of the two sets of fixing components 2 are respectively used to clamp the two sides 101 of the battery pack 100. By clamping the two sides 101 of the battery pack 100 respectively by the clamping members 23 of the two sets of fixing components 2, the firmness of the battery pack 100 is further improved, and the reliability and stability are enhanced.

[0030] The working principle of this energy storage battery pack mounting and fastening structure is as follows: The clamping member 23 and the rotating shaft 21 are rotated together to a position above the side 101 of the battery pack 100, allowing the battery pack 100 to be placed onto the bracket 1 through the opening 11. The rotating shaft 21 is then rotated until the clamping member 23 presses against and tightens against the side 101 of the battery pack 100. The limiting member 22 is connected to the rotating shaft 21 to provide a limiting and fixing connection for the battery pack 100. When it is necessary to remove the battery pack 100, the limiting member 22 and the rotating shaft 21 are released, and the clamping member 23 and the rotating shaft 21 rotate together to a position above the side 101 of the battery pack 100, allowing the battery pack 100 to be removed from the opening 11. This energy storage battery pack mounting and fastening structure achieves limiting while also preventing the battery pack 100 from shifting, and facilitates the installation of the battery pack 100.

[0031] Based on the same concept, the second aspect of the present invention, combined with... Figures 6-8 As shown, a battery cluster is proposed, including a housing 200, a battery pack 100, and an energy storage battery pack mounting and fastening structure as described in the first aspect embodiment. The bracket 1 is fixed to the inner wall of the housing 200, and the battery pack 100 is placed on the bracket 1 through the opening 11.

[0032] The battery cluster proposed in this embodiment, the limiting member 22, not only achieves the limiting function, but also prevents the battery pack 100 from moving around, and facilitates the installation of the battery pack 100.

[0033] In some embodiments, one end of the rotating shaft 21 extends out of the housing 200, and the limiting member 22 is located outside the housing 200. Since both one end of the rotating shaft 21 and the limiting member 22 are located outside the housing 200, it is convenient to rotate the rotating shaft 21 via the actuator 25 and to use the limiting member 22 to limit the rotation of the rotating shaft 21. Operation can be performed without disassembling the housing 200, resulting in good operational convenience.

[0034] Based on the same concept, a third aspect of this utility model proposes an energy storage container, including a container body and a battery cluster as described in the second aspect embodiment, wherein the battery cluster is disposed within the container body.

[0035] In this embodiment of the Chuneng container, the battery pack 100 is located in the battery cluster. The limiting member 22 not only limits the movement of the battery pack 100, but also prevents it from moving around, and facilitates the installation of the battery pack 100.

[0036] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
