Description

Technical Field

[0001] This utility model relates to the field of energy storage battery PACK installation technology, specifically to an energy storage battery PACK load-bearing guide rail with limiting and positioning. Background Technology

[0002] A battery storage pack is a modular unit that integrates multiple individual energy storage batteries through specific connection methods, structural designs, and auxiliary systems. It possesses complete energy storage, management, and output functions. It is the core component of an energy storage system, enabling efficient energy storage and flexible application; essentially, it combines the energy container and control center of the system. Currently, large-scale energy storage projects, industrial and commercial energy storage projects, and residential energy storage projects all involve battery storage cabinets. These cabinets need to house the battery packs. Since these cabinets have a certain height and depth, the guide rails supporting the battery packs are typically welded to both sides of the cabinet. The uprights lack lateral guidance on the guide rails and have no restrictive structure at the rear. Typically, during loading, a forklift is used to place the battery pack in a suitable position in front of the cabinet, and then manual adjustment of the angle and position is used to push the battery pack forward. Due to the large weight of the energy storage battery pack, the pushing force may vary, causing collisions, deformation, and positional deviations. This can damage the protective layers of the cabinet and the battery pack, leading to rust and posing a potential risk to the safe use of the equipment. Furthermore, it increases the time and difficulty of correcting the correct installation position of the pack, thereby reducing loading efficiency and the safety of personnel and equipment.

[0003] The following problems exist in the existing energy storage battery installation process: 1. The heavy weight of the energy storage battery pack can cause the guide rail to deform, making it inconvenient for battery pack installation and maintenance, and will also affect the connection and installation of electrical wiring harnesses. 2. The placement angle of the energy storage battery pack may be off. When the energy storage battery pack is installed and pushed in, it may collide with the column, causing damage to the protective layer of the cabinet and the battery pack itself, resulting in rust, deformation and other appearance defects, and even posing potential risks to the safe use of the equipment. 3. After the PACK is installed and pushed in, due to the lack of a limiting process at the tail of the guide rail, the battery PACK may be loaded too deeply, resulting in secondary or tertiary collisions. This requires a pull-back operation, which is laborious and time-consuming. This increases the time and difficulty of correcting the PACK's installation position, thereby reducing loading efficiency and the safety of personnel and equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a load-bearing guide rail for energy storage battery packs, which maintains the stability of device installation, avoids excessive loading of energy storage battery packs and collisions, thereby reducing the need for correcting the correct installation position of energy storage battery packs, lowering the difficulty, improving efficiency and equipment safety, and enhancing the stability of energy storage battery pack installation, thus solving the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a load-bearing guide rail for energy storage battery packs, comprising a load-bearing body welded to the inner wall of a cabinet, a guide rail mounting plate slidably mounted on the side of the load-bearing body, and a threaded groove for embedding bolts on the side of the guide rail mounting plate. The guide rail mounting plate is fixed to the side wall of the load-bearing body by bolt threads inside the threaded groove. The threaded grooves are arranged in groups of two, for a total of four groups, which are arranged opposite to each other on the sides of the two ends of the guide rail mounting plate. The outer side of the guide rail mounting plate is connected to the guide rail body. A guide plate is provided at the side end of the guide rail body away from the guide rail mounting plate. A limiting base plate is provided at the bottom end of the guide rail body near the inner wall of the cabinet. The inner side of the limiting base plate is covered with a rubber pad. A guide structure is provided at the top end of the guide rail body away from the inner wall of the cabinet. The guide structure is set as an inclined plate. A support structure is welded to the inner wall of the cabinet at the bottom of the load-bearing body.

[0006] Preferably, the supporting body includes a connecting end welded to the inner wall of the cabinet, with an upper mating end at the top of the connecting end on the side away from the inner wall of the cabinet, and a lower mating end at the bottom of the side away from the inner wall of the cabinet. The guide rail mounting plate includes an upper connecting tooth that mates with the upper mating end, and the guide rail mounting plate also includes a lower connecting tooth that mates with the lower mating end. The shape and size of the upper connecting tooth and the lower connecting tooth are respectively able to fit into the upper mating end and the lower mating end.

[0007] Preferably, the guide rail body is L-shaped, and the vertical end of the L-shaped guide rail body is welded to the outer side of the guide rail mounting plate to form a fixed structure.

[0008] Preferably, the support structure is triangular, and the top support surface of the support structure extends from the bottom of the load-bearing body to the bottom of the guide plate.

[0009] Preferably, the top of the inner side of the guide plate is provided with an arc.

[0010] Compared with the prior art, this utility model provides a load-bearing guide rail for energy storage battery packs, which has the following advantages: This invention supports and fixes the guide rail mounting plate and guide rail body through upper connecting teeth, lower connecting teeth, upper docking ends, and lower docking ends, maintaining the stability of the device installation. Rubber pads effectively isolate the energy storage battery pack from collisions with the limiting base plate, preventing the energy storage battery pack from being loaded too deeply and causing collisions. This reduces the need for correcting the correct installation position of the energy storage battery pack, lowers the difficulty, and improves efficiency and equipment safety. A triangular support structure supports the guide rail body; the inherent mutual constraints of the triangles prevent deformation under stress, increasing the stability from the bottom of the load-bearing body to the bottom of the guide plate, thus enhancing the stability of the energy storage battery pack installation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] A load-bearing guide rail based on an energy storage battery pack includes a load-bearing body 1 welded to the inner wall of a cabinet. A guide rail mounting plate 2 is slidably mounted on the side of the load-bearing body 1. The side of the guide rail mounting plate 2 has a threaded groove for embedding bolts. The guide rail mounting plate 2 is fixed to the side wall of the load-bearing body 1 by bolt threads inside the threaded groove. There are four sets of threaded grooves, each set consisting of two grooves. The four sets of threaded grooves are arranged opposite each other on the sides of the two ends of the guide rail mounting plate 2. The outer side of the guide rail mounting plate 2 is connected to the guide rail body 3. A guide plate 4 is provided at the side end of the guide rail body 3 away from the guide rail mounting plate 2. A limiting base plate 5 is provided at the bottom end of the guide rail body 3 near the inner wall of the cabinet. The inner side of the limiting base plate 5 is covered with a rubber pad. A guide structure 6 is provided at the top end of the guide rail body 3 away from the inner wall of the cabinet. The guide structure 6 is set as an inclined plate. A support structure 7 is welded to the inner wall of the cabinet at the bottom of the load-bearing body 1.

[0017] Furthermore, the supporting body 1 includes a connecting end 101 welded to the inner wall of the cabinet. The top of the connecting end 101 on the side away from the inner wall of the cabinet is provided with an upper mating end 102, and the bottom of the side away from the inner wall of the cabinet is provided with a lower mating end 103. The guide rail mounting plate 2 includes an upper connecting tooth 201 that mates with the upper mating end 102. The guide rail mounting plate 2 also includes a lower connecting tooth 202 that mates with the lower mating end 103. The shape and size of the upper connecting tooth 201 and the lower connecting tooth 202 can respectively fit into the upper mating end 102 and the lower mating end 103.

[0018] Furthermore, the guide rail body 3 is L-shaped, and the vertical end of the L-shaped guide rail body 3 is welded to the outer side of the guide rail mounting plate 2 to form a fixed structure.

[0019] Furthermore, the support structure 7 is triangular, and the top support surface of the support structure 7 extends from the bottom of the load-bearing body 1 to the bottom of the guide plate 4.

[0020] Furthermore, an arc 8 is provided at the top of the inner side of the guide plate 4.

[0021] Example 1 According to the instruction manual Figure 1-4 The supporting body 1, welded to the inner wall of the cabinet, provides installation space for the guide rail mounting plate 2 and supports it. Before use, the upper connecting teeth 201 of the guide rail mounting plate 2 are aligned with the upper mating end 102 of the supporting body 1, and the lower connecting teeth 202 of the guide rail mounting plate 2 are aligned with the lower mating end 103 of the supporting body 1. The guide rail mounting plate 2 is slid, so that the upper connecting teeth 201 and the lower connecting teeth 202 of the guide rail mounting plate 2 slide and advance inside the upper mating end 102 and the lower mating end 103 of the supporting body 1, respectively, to support and fix the guide rail mounting plate 2. At the same time, since the vertical end of the "L"-shaped guide rail body 3 is welded to the outside of the guide rail mounting plate 2, when the guide rail mounting plate 2 is installed inside the supporting body 1, the "L"-shaped guide rail body 3 is simultaneously supported and fixed, maintaining the initial stability of the "L"-shaped guide rail body 3.

[0022] When installing the energy storage battery pack, the energy storage battery pack needs to be equipped with a mounting rail that is compatible with this mounting guide rail. The mounting rail only needs to be able to mate with the guide rail body 3 and the guide plate 4. This technical solution can be designed based on the shape of the guide rail body 3 and the guide plate 4 in this mounting guide rail. At the same time, this part is not part of the technical points of this application, so it will not be described in detail here.

[0023] When installing the energy storage battery pack, align the bottom of the energy storage battery pack with the guide structure 6 of the inclined plate, and then push the energy storage battery pack. When pushing the energy storage battery pack manually, it can effectively correct the left and right position deviation of the energy storage battery pack and avoid collisions with the cabinet. Continue to push the energy storage battery pack, and under the guidance of the guide structure 6, the energy storage battery pack enters the guide rail body 3 until the top of the energy storage battery pack contacts the limiting base plate 5, thereby limiting the top of the energy storage battery pack. The rubber pad covering the inner side of the limiting base plate 5 is any publicly available rubber pad made of various rubber materials. When the top of the energy storage battery pack contacts the limiting base plate 5, the rubber pad effectively isolates the energy storage battery pack from the limiting base plate 5, which can avoid the energy storage battery pack being loaded too deep and collisions. This reduces the time required to correct the correct installation position of the energy storage battery pack, reduces the difficulty, improves efficiency and equipment safety.

[0024] After the energy storage battery PACK is installed, the guide rail body 3 is supported by the triangular support structure 7. The mutual restraint relationship of the triangles makes it difficult for the triangular support structure 7 to deform under force, thereby increasing the stability from the bottom of the load-bearing body 1 to the bottom of the guide plate 4 and improving the stability of the energy storage battery PACK installation.

[0025] Example 2 According to the instruction manual Figure 5-6 When the energy storage battery PACK is being pushed forward, the matching installation track slides inside the guide rail body 3 and the guide plate 4. The conical inner wall of the guide plate 4 causes a sudden change in geometry due to the sharp angles of the conical surface. During sliding, contact is only made through a few edges, resulting in a sharp increase in the pressure per unit area. Peak stress exceeding the yield strength of the material is easily generated at the sharp corners, accelerating fatigue and leading to crack initiation. To solve this problem, an arc 8 is set at the top of the inner side of the guide plate 4 to increase the force-bearing area. The smooth and continuous arc surface of the arc 8 can distribute the contact pressure to the entire surface, avoiding wear or deformation caused by local high pressure, thereby improving the service life of the device.

[0026] In use, firstly, align the upper connecting teeth 201 of the guide rail mounting plate 2 with the upper mating end 102 of the support body 1, and align the lower connecting teeth 202 of the guide rail mounting plate 2 with the lower mating end 103 of the support body 1. Slide the guide rail mounting plate 2 so that the upper connecting teeth 201 and lower connecting teeth 202 of the guide rail mounting plate 2 slide and advance inside the upper mating end 102 and lower mating end 103 of the support body 1, respectively, to support and fix the guide rail mounting plate 2 and the guide rail body. Align the bottom end of the energy storage battery PACK with the guide structure 6 of the inclined plate, and then push the energy storage battery PACK. When pushing the energy storage battery PACK manually, it can effectively correct the left and right position deviation of the energy storage battery PACK and avoid collisions with the cabinet. Continue to push the energy storage battery PACK, and the energy storage battery PACK will move along the guide structure 6. Guided by the guide plate 4, the battery pack enters the guide rail body 3 until the top of the battery pack contacts the limiting base plate 5, thus limiting the top of the battery pack. When the top of the battery pack contacts the limiting base plate 5, the rubber pad effectively isolates the battery pack from the limiting base plate 5, preventing collisions and avoiding excessive loading of the battery pack. This reduces the need to correct the correct installation position of the battery pack, lowers the difficulty, and improves efficiency and equipment safety. After the battery pack is installed, the guide rail body 3 is supported by the triangular support structure 7. The mutual restraint of the triangles makes it difficult for the triangular support structure 7 to deform under force, thereby increasing the stability from the bottom of the load-bearing body 1 to the bottom of the guide plate 4 and improving the stability of the battery pack installation.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
