Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a battery rack for an energy storage container. Background Technology

[0002] With the rapid development of the energy storage industry, energy storage containers have emerged as a new energy storage solution. Energy storage containers typically house lithium-ion battery packs, enabling them to efficiently store large amounts of electrical energy. The installation and securing of these battery packs are usually handled by battery racks, whose design must consider not only strength and transport reliability but also assembly efficiency.

[0003] After the battery pack is pushed and installed onto the guide rails of the battery rack, it needs to be secured to the rack in various directions (X, Y, Z) by limiting its position to maintain reliability and stability during transportation. In existing technologies, the installation of the battery pack onto the rack often suffers from insufficient limiting accuracy and inadequate limiting directions, leading to the battery pack being placed too far forward, too far back, too far to the left, or too far to the right. This results in insecure and unreliable fixing of the battery pack to the rack, and also affects the efficiency of battery pack fixing and assembly. Utility Model Content

[0004] Based on this, the present invention provides an energy storage container battery rack, which aims to solve the problems of low limiting accuracy, inaccurate limiting direction, deviation in placement position, unstable fixing, poor assembly reliability and low assembly efficiency in the existing battery rack assembly of battery packs.

[0005] To achieve the above objectives, the present invention proposes the following technical solution: an energy storage container battery rack, applicable to containers, comprising several first square tubes, several second square tubes, several layers of first guide rails, and several layers of second guide rails; the several first square tubes are arranged parallel to each other, and the several layers of first guide rails are arranged from top to bottom on the sides of the first square tubes near the second square tubes, each layer of first guide rails being connected to each first square tube through a first support plate; the several second square tubes are arranged parallel to each other, and the several layers of second guide rails are arranged from top to bottom on the sides of the second square tubes near the first square tubes, each layer of second guide rails being connected to each second square tube through a second support plate; the first square tubes and second square tubes are arranged symmetrically one to one; the first guide rails and second guide rails are arranged symmetrically one to one.

[0006] In a preferred embodiment, each layer of the first guide rail has a first support plate corresponding to a first square tube; each layer of the second guide rail has a second support plate corresponding to a second square tube. By welding the first guide rail to the first square tube using the first support plate and the second guide rail to the second square tube using the second support plate, the stress resistance of the first and second guide rails can be effectively increased.

[0007] In a preferred embodiment, each layer of the first guide rail is provided with a first U-shaped structure at one end near the back of the container, and the bottom of the first U-shaped structure abuts against the end of the first guide rail; each layer of the second guide rail is provided with a second U-shaped structure at one end near the back of the container, and the bottom of the second U-shaped structure abuts against the end of the second guide rail.

[0008] In a preferred embodiment, the first U-shaped structure and the second U-shaped structure are symmetrically arranged; the first U-shaped structure is adapted to the first guide rail; and the second U-shaped structure is adapted to the second guide rail.

[0009] In a preferred embodiment, the first guide rail and the second guide rail are respectively adapted to the battery pack they support.

[0010] In a preferred embodiment, a first stop is provided at the end of each layer of the first guide rail away from the back of the container, and the first stop is fixed to the first guide rail through a first stop fixing hole; the first stop is adapted to the first guide rail.

[0011] In a preferred embodiment, the top of the first stop is provided with a first limiting edge, which extends along the Z-axis. The first stop effectively restricts the movement of the battery pack in both the front-back and vertical directions, making the battery pack safer and more reliable during transportation.

[0012] In a preferred embodiment, a second stop is provided at the end of each layer of the second guide rail away from the back of the container, and the second stop is fixed to the second guide rail through a second stop fixing hole; the second stop is adapted to the second guide rail.

[0013] In a preferred embodiment, the top of the second stop is provided with a second limiting edge, which extends along the Z-axis. The second stop effectively restricts the movement of the battery pack in both the front-back and vertical directions, making the battery pack safer and more reliable during transportation.

[0014] In a preferred embodiment, a first limiting block is provided on the bottom surface of the battery pack near the end of the first U-shaped structure, and the first limiting block is adapted to the first guide rail; a second limiting block is provided on the bottom surface of the battery pack near the end of the second U-shaped structure, and the second limiting block is adapted to the second guide rail.

[0015] In a preferred embodiment, each end corner of the first limiting block and each end corner of the second limiting block are chamfered. By setting the first and second limiting blocks and making their end corners chamfered, they can cooperate with the side of the guide rail for limiting, allowing the battery pack to be pushed and installed smoothly.

[0016] In a preferred embodiment, several layers of third guide rails are also provided on the side of the first square tube away from the first guide rail; the third guide rails are symmetrically arranged with the first guide rails; the third guide rails have the same structure as the first guide rails.

[0017] In a preferred embodiment, several layers of fourth guide rails are also provided on the side of the second square tube away from the second guide rail; the fourth guide rails are symmetrically arranged with the second guide rails; the fourth guide rails and the second guide rails have the same structure.

[0018] When using the structure of this application, the first and second square tubes can be welded and fixed inside the container, and the battery pack can be installed and fixed by the battery rack.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0020] (1) The structure of this application makes the assembly gap of the battery pack more reasonable: a first limiting block and a second limiting block are set on the battery pack. The size of the two limiting blocks is wider than the liquid cooling base plate of the battery pack. The two limiting blocks and the side of the corresponding guide rails retain an installation gap of 2-3mm. At the same time, chamfering (introduction) design is made at the end corners (left, right and front) of each limiting block, which can transition from large gap to small gap, and can smoothly and accurately push and install the battery pack on the guide rail.

[0021] (2) Through the structure of this application, the battery pack can be fully limited in the three directions of X, Y and Z: the two sides of the two guide rails can limit the battery pack in the X direction, and the two U-shaped structures can limit the battery pack in the Y and Z directions; in addition, an M10 screw is provided at one end of the battery pack near the limiting block, and the battery pack can be limited in the Y and Z directions through the limiting block and the M10 screw.

[0022] (3) The structure of this application is simple and the cost is low: the battery rack structure is made of sheet metal bending and welding process, the guide rail is made of sheet metal bending and welding process, and the support plate is made of bending process. The manufacturing process is mature and reliable. Under the premise of ensuring product performance, the production cost is greatly reduced, which has obvious cost advantage, higher practicality and economy, and can be produced and used as a general product.

[0037] Currently, existing battery rack technologies have the following drawbacks: (1) Excessive assembly gap: When the battery pack is installed on the battery rack, the gap is too large, causing the battery pack to be offset to the left or right, which makes production and installation difficult and wastes production time. (2) Insufficient limiting direction: When the battery pack is installed on the battery rack, it is often only limited to two directions, which poses certain risks and safety hazards in actual transportation. (3) Complex structure and high cost: The battery rack guide rail structure is complex, the support plate is often a whole plate structure, and the guide rail is also fixed by screws and nuts, which is costly.

[0038] The following problems can be solved through the structure of this application:

[0039] (1) Solve the problem of excessive assembly gap: A limiting block is designed on the left and right sides of the rear end of the battery pack. The limiting blocks are designed with chamfer (introduction) structure on the left and right / front and back, which can meet the installation requirements from large gap to small gap.

[0040] (2) Solve the problem of insufficient limiting direction: In addition to a limiting block designed on the left and right sides of the rear end of the battery pack, a stop block is also designed on the left and right sides of the front end of the battery pack, which can simultaneously satisfy the limiting and installation of the battery pack in the X, Y and Z directions.

[0041] (3) Solve the problem of complex structure and high cost: The battery rack guide rail adopts a U-shaped structure for limiting, which is simple and reliable and can meet the transportation needs under different road conditions.
