[0001] The utility model relates to the technical field of parts assembly, processing and application, and in particular to an inner bottom plate component and a fixing mechanism of an energy storage cabinet. Background Art

[0002] Energy storage cabinets, as important backup energy devices, can help solve numerous power consumption issues. Since their primary function is to properly house modules, provide a favorable and controllable working environment for their use, and facilitate collective control of individual modules, existing cabinet designs are designed to meet these functional requirements.

[0003] The inner bottom plate assembly is one of the main load-bearing mechanisms of the energy storage equipment. The load-bearing stability of the existing inner bottom plate assembly for the energy storage equipment needs to be improved. At the same time, the inner bottom plate assembly is welded, but the inner bottom plate assembly contains multiple parts. During welding, the positioning accuracy of the existing equipment is not high and cannot meet the needs of fast and high-precision welding production. Summary of the Invention

[0004] The embodiment of the present application provides an inner bottom plate assembly and a fixing mechanism for an energy storage cabinet. The inner bottom plate assembly is arranged reasonably, providing a stable support surface while making the wiring neater and more orderly, reducing failures and safety hazards caused by chaotic wiring. The fixing mechanism determines the position of the first mounting seat through the positioning structure, thereby determining the position of the second limiting structure to determine the position of the strip workpiece, thereby improving the positioning accuracy of the equipment and thus improving the product production quality.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an inner bottom plate assembly of an energy storage cabinet, the inner bottom plate assembly including a bottom plate, a strip workpiece, and an L-shaped workpiece, a through hole is provided at the center line of the bottom plate, the strip workpiece is provided at the front end of the through hole, the lower end of the strip workpiece is connected to the upper end of the bottom plate, a convex plate is provided at the front end of the bottom plate, two L-shaped workpieces are provided and are provided on both sides of the strip workpiece, and the lower end of the L-shaped workpiece is connected to the upper end of the bottom plate.

[0006] Compared with the prior art, the advantages of the present invention are:

[0007] As the foundation of the entire inner bottom plate assembly, the bottom plate provides a stable support surface, and the through-hole design at the center line of the bottom plate facilitates wiring or other functional requirements.

[0008] As an improvement, the L-shaped workpiece includes a vertical workpiece parallel to the strip workpiece and a horizontal workpiece perpendicular to the strip workpiece. One side of the horizontal workpiece is connected to one side of the vertical workpiece, and the other sides of the two horizontal workpieces are respectively connected to both sides of the strip workpiece. The width of the strip workpiece is greater than the width of the vertical workpiece. Due to the arrangement of the L-shaped workpiece and the strip workpiece, more space and convenience are provided for wiring. This design makes wiring neater and more orderly, reducing faults and safety hazards caused by chaotic wiring.

[0009] The locking mechanism is configured to lock the locking cam of the locking cam, wherein the locking cam is secured to the locking cam of the locking cam and secured to the bottom of the locking cam. The locking cam is secured to the bottom of the locking cam and secured to the bottom of the locking cam.

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] By providing a positioning column that abuts against the side wall of the through hole, the position of the base plate is determined and the rear end of the base plate is fixed. At the same time, the side wall of the upper end of the positioning column abuts against the side wall of the first groove provided in the positioning block, thereby determining the position of the positioning column, thereby determining the position of the first cylinder, thereby determining the position of the first mounting seat, and thereby determining the position of the second limiting structure. Since the lower end of the second limiting structure abuts against the strip workpiece and the outer wall of the positioning block abuts against the rear end of the strip workpiece, the position of the strip workpiece on the upper end of the base plate is determined, thereby improving the positioning accuracy of the equipment and thus improving the production quality of the product.

[0012] Since the strip workpiece is long, the second limiting structure is provided at the front and rear ends of the strip workpiece, which can better limit the strip workpiece and also better position the strip workpiece.

The fourth limiting structure is arranged on both sides of the second mounting seat. The front end of the fourth limiting structure is against the rear end of the vertical workpiece. The first limiting structure plays a limiting role by being against the base plate; since the third limiting structure is arranged on the first mounting seat, after the first mounting seat determines its position, the position of the third limiting structure is determined, and the lower end of the third limiting structure is against the L-shaped workpiece, thereby determining the position of the L-shaped workpiece, further improving the positioning accuracy of the equipment; since the front end of the fourth limiting structure is against the rear end of the vertical workpiece, the rear end of the vertical workpiece is limited and positioned.

The first limiting blocks are horizontally arranged and arranged on both sides of the base plate and below the corresponding strip workpiece. The second limiting blocks are vertically arranged and arranged below the corresponding vertical workpiece. Since the width of the strip workpiece is greater than the width of the vertical workpiece, in order to reduce the pressure between the first limiting block and the strip workpiece and the second limiting block and the vertical workpiece, the first limiting block is horizontally arranged and the second limiting block is vertically arranged, which increases the contact area between the first limiting block and the strip workpiece and the second limiting block and the vertical workpiece, thereby improving the stability of the strip workpiece and the vertical workpiece during spot welding with the base plate.

[0015] As an improvement, a limiting arm is provided on one side of the two first limiting blocks on both sides of the front end of the base plate, and the side walls of the limiting arms are abutted against the side walls of the convex plate. By abutting against the side walls of the limiting arms and the side walls of the convex plate, the first limiting blocks limit the front end of the base plate to prevent the base plate from moving, thereby improving the stability and accuracy during welding.

[0016] As an improvement, the second limiting structure includes a second cylinder, a second push rod, and a third limiting block. The second cylinder is connected to one end of the second push rod and drives the second push rod to move up and down.

The fourth limiting block is arranged at the front end of the third mounting seat, the fifth limiting block is arranged at the rear end of the third mounting seat, and the sixth limiting block is arranged on one side of the third mounting seat. The rear end of the fourth limiting block is against the front end of the horizontal workpiece, and the front end of the fifth limiting block is against the rear end of the horizontal workpiece. The ends are abutted, one side of the sixth limit block abuts against the other side of the front end of the vertical workpiece, the lower end of the third mounting seat is protruded with a seventh limit block, the lower end of the seventh limit block abuts against the upper end of the horizontal workpiece, the rear end of the fourth limit block abuts against the front end of the horizontal workpiece, the front end of the fifth limit block abuts against the rear end of the horizontal member, and the lower end of the seventh limit block abuts against the upper end of the horizontal workpiece, thereby realizing the positioning and limiting of the horizontal workpiece, and one side of the sixth limit block abuts against the other side of the front end of the vertical workpiece, thereby realizing the limiting of the front end of the vertical workpiece.

[0018] As an improvement, the fourth limiting structure includes a fourth cylinder, a fourth push rod, a fourth mounting seat, an eighth limiting block, a ninth limiting block, and a tenth limiting block. The fourth cylinder is connected to one end of the fourth push rod and drives the fourth push rod to move forward and backward. The other end of the fourth push rod is connected to the fourth mounting seat. The eighth limiting block and the ninth limiting block are arranged on both sides of the upper end of the fourth mounting seat. One side of the eighth limiting block and the ninth limiting block are respectively abutted against both sides of the rear end of the vertical workpiece. The tenth limiting block is arranged at the upper end of the vertical workpiece. The lower end of the tenth limiting block is abutted against the upper end of the vertical workpiece. The eighth limiting block and the ninth limiting block are respectively abutted against both sides of the rear end of the vertical workpiece. The lower end of the tenth limiting block is abutted against the upper end of the vertical workpiece, thereby limiting the two sides and the upper end of the vertical workpiece, thereby improving the stability of the vertical workpiece during welding.

[0019] As an improvement, the positioning structure also includes a protrusion and a concave block. The protrusion is arranged at the front end of the fourth mounting seat, and the concave block is arranged at the rear end of the second limiting block corresponding to the protrusion. The fourth cylinder drives the fourth push rod to move forward so that the concave block and the protrusion are offset against each other. The position of the fourth limiting structure is determined by the offset between the concave block and the protrusion, thereby determining the position of the rear end of the vertical workpiece, thereby determining the accuracy of the vertical workpiece welding.
