[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] See Figures 1-11 This utility model provides an energy storage cabinet base that enables rapid positioning and installation, including a cabinet body 2, a lower base 1, and a locking mechanism 3. The cabinet body 2 is a rectangular structure and serves as an installation carrier for installing battery modules and other components. An upper base 21 is provided at the bottom of the cabinet body 2. The upper base 21 is a rectangular structure with its edges basically flush with the side walls of the cabinet body 2. First corner pieces 22 are provided at the four corners of the upper base 21. The first corner pieces 22 are rectangular structures with a hollow structure, and are cast in shape, similar to the corner pieces on a shipping container. An oblong hole (racetrack type) is provided on the bottom surface of the first corner piece 22. The oblong hole is a through hole that connects to the interior and forms a first locking hole 220. The first locking holes on the four first corner pieces face the same direction, that is, their length directions are parallel to each other. In this embodiment, they can be parallel to the length or width direction of the cabinet body.

[0035] The lower base 1 is embedded in the ground and is horizontal after embedding. It is used to connect with the upper base 21. In this embodiment, the lower base is a rectangular structure that matches the size of the upper base 21. Four second corner pieces 11 are provided at the four corners of the lower base 1, which correspond one-to-one with the first corner pieces 22 on the upper base. The structure of the second corner piece 11 is basically the same as that of the first corner piece. It is a cuboid structure with a hollow interior and is cast. A waist-shaped hole (racetrack type) is provided on the upper surface of the second corner piece 11 to form a second locking hole 110. The orientation and size of the second locking hole 110 are the same as those of the first locking hole 220 to ensure accurate alignment when the upper and lower bases are connected. The first corner piece and the second corner piece are connected by a locking mechanism to achieve rapid positioning and installation of the energy storage cabinet, thereby improving installation efficiency and stability.

[0036] Four locking mechanisms 3 are respectively arranged between each of the first corner pieces 22 and the second corner pieces 11 to connect the first corner pieces and the second corner pieces, thereby achieving rapid fixation of the upper and lower bases. Specifically, the locking mechanism 3 includes a housing 31, which is a rectangular parallelepiped structure with a relatively small thickness, made of high-strength metal. A first locking block 32 is rotatably mounted on the upper bottom surface of the housing 31. The rotation axis of the first locking block is perpendicular to the horizontal plane, and it can be axially inserted into the first locking hole 220. The cross-section of the first locking block 32 is oblong, matching the shape of the first locking hole 220, and its size is slightly smaller than that of the first locking hole 220. The top surface of the first locking block is an arc-shaped surface, forming a guide surface to achieve rapid positioning and installation. The bottom surface is a plane, serving as a support surface during locking, for contacting the inner wall of the first corner piece to achieve axial locking. A first locking mechanism 32 is provided inside the housing 31. A driving assembly is provided, which drives the first locking block 32 to rotate 90 degrees to lock and fix the first corner piece. A second locking block 35 is rotatably mounted on the lower bottom surface of the housing 31. The rotation axis of the second locking block is also perpendicular to the horizontal plane. In this embodiment, it is coaxial with the first locking block. The cross-section of the second locking block 35 is also waist-shaped, matching the shape of the second locking hole 110. Its size is slightly smaller than the second locking hole 110 to ensure smooth insertion. Its top surface (i.e., the lower end face) is also an arc-shaped surface, forming a guiding surface, which can realize quick positioning and installation. The upper bottom surface is a plane, which serves as a support surface during locking and is used to fit and contact the inner wall of the second corner piece to achieve axial locking. A second driving assembly is provided inside the housing 31. The second driving assembly drives the second locking block 35 to rotate 90 degrees to lock and fix the second corner piece, ensuring that the upper and lower bases can be quickly connected and improving assembly efficiency.

[0037] In this embodiment, the upper bottom surface of the housing 31 is the upper support surface, which can fit and contact the bottom surface of the first corner piece 22. A first positioning boss 311 is provided on the upper support surface, which can be axially inserted into the first locking hole 220. The thickness of the first positioning boss 311 is the same as the depth of the first locking hole 220, and the cross-section of the first positioning boss 311 is also waist-shaped, which perfectly matches the shape of the first locking hole 220 to ensure accurate insertion. In order to achieve rapid positioning, chamfers are provided on the edges of the first positioning boss 311 and the first locking hole 220. A first guiding surface is formed for rapid positioning during docking. A first locking block 32 is mounted on a first positioning boss 311. The lower bottom surface of the housing 31 is a lower support surface, which can fit and contact the top surface of the second corner piece 11. A second positioning boss 312 is provided on the lower support surface, which can be axially inserted into the second locking hole 110. The thickness of the second positioning boss 312 is the same as the depth of the second locking hole 110, and the cross-section of the second positioning boss 312 is also waist-shaped, which perfectly matches the shape of the second locking hole 110 to ensure accurate insertion. Chamfers are provided on the edges of the second positioning boss 312 and the second locking hole 110 to form a second guiding surface, which is used for rapid positioning during docking, improving assembly efficiency and accuracy. A second locking block 35 is mounted on the second positioning boss 312.

[0038] In this application, the housing 1 consists of an upper housing 31a and a lower housing 31b, which are fixed together by bolts, forming an internal mounting cavity for mounting the first and second drive components. Specifically, a first shaft and a second shaft are rotatably mounted inside the housing 1. The first shaft and the second shaft are coaxially arranged and perpendicular to the upper and lower bottom surfaces of the housing. The upper end of the first shaft extends outside the housing 1, and a first locking block 32 is fixed to the end of the first shaft. In this embodiment, the first locking block is integrally formed with the first shaft. The first drive component includes a first gear 33 and a first rack 34. The first gear 33 is fixed to the end of the first shaft, and its sidewall is provided with teeth. In this embodiment, the first gear 33 is an incomplete gear. The first rack 34 is horizontally slidably fitted inside the housing, and it is connected to the first shaft. The teeth of the first gear 33 mesh, and the sliding of the first rack drives the first gear to rotate, thereby driving the first locking block to rotate and realizing the locking function. The lower end of the second shaft extends to the outside of the housing 1, and the second locking block 35 is fixed to the end of the second shaft. In this embodiment, the second locking block is integrally formed with the second shaft. The second drive assembly includes a second gear 36 and a second rack 37. The second gear 36 is fixed to the end of the second shaft, and its side wall is provided with teeth. In this embodiment, the second gear 36 is an incomplete gear. The second rack 37 is horizontally slidably fitted in the housing and is parallel to the first rack. The teeth of the second rack 37 mesh with the teeth of the second gear 36. The sliding of the second rack drives the second gear to rotate, thereby driving the second locking block to rotate and realizing the locking function.

[0039] Meanwhile, in this application, a first elastic component is provided inside the housing 1. This first elastic component causes the first locking block and the second locking block to have a tendency to rotate in the locking direction. Even if the first locking block and the second locking block have a tendency to rotate radially by 90 degrees, so that they are in the locking angle, in the locked state, the angle between the length direction of the first locking block and the length direction of the first lock shell is 90 degrees, and the angle between the length direction of the second locking block and the length direction of the second lock hole is also 90 degrees. This state is the initial state. In this embodiment, the first elastic component includes a first compression spring 342 that causes the first rack 34 to have an inward movement tendency and a second compression spring 372 that causes the second rack 37 to have an inward movement tendency.

[0040] Meanwhile, a pulling part is provided at the end of the first rack and the second rack. The pulling part is used to pull the first or second rack to slide axially, thereby overcoming the spring force to move outward, driving the gear to rotate, and causing the first and second locking blocks to rotate in the unlocking direction. In the unlocked state, the length direction of the first (or second) locking block is parallel to the length direction of the first (or second) lock hole. At this time, the first (or second) locking block can be pulled out from the first (or second) lock hole to achieve unlocking. The pulling part is a pull block 371 or a steel wire rope. When it is a pull block, it is T-shaped or L-shaped to facilitate the application of force. When it is a steel wire rope, it can realize remote operation, similar to a brake cable.

[0041] A limiting structure is provided on the housing to limit the rotation angle of the first locking block and the second locking block, so that the maximum rotation angle is 90 degrees. In this embodiment, the limiting structure includes an arc-shaped limiting groove 350 provided on the end face of the first or second locking block. The central angle formed between the two ends of the limiting groove and the axis of the locking block is 90 degrees. At the same time, a limiting block is provided in the housing, which is fitted in the limiting groove to realize the limiting function and ensure that the rotation angle of the locking block is accurate.

[0042] Multiple fixing bolts 5 are vertically arranged on the lower base. Meanwhile, a strip-shaped mounting hole 2100, allowing the fixing bolts 5 to pass through axially, is provided on the bottom surface of the upper base. An operating window 210 is provided on the side wall of the upper base, facing the mounting hole 2100, for installing nuts. A cover plate 23 is detachably installed on the operating window 210 to cover it and improve aesthetics. In this embodiment, the lower and upper bases are welded from channel steel, with the opening of the channel steel facing inwards. The fixing nut 5 includes a rectangular positioning plate 52. A bolt body 51 is vertically fixed at the center of the positioning plate 52. At least three reinforcing ribs 53 are provided between the bolt body and the upper surface of the positioning plate 52 to improve overall strength and ensure the verticality of the bolt body. The positioning plate is placed on the bottom surface of the opening of the channel steel of the lower base and fixed by welding. A hole is provided on the top surface of the opening of the channel steel, allowing the bolt body to pass through, forming a connecting end for connection with the upper base.

It is also easy to disassemble, facilitating maintenance and upkeep. Corner fittings at the four corners enhance overall structural strength and compressive resistance, improving base stability, preventing deformation, extending service life, and ensuring stable cabinet installation.
