[0002] The energy storage device generally includes a cluster frame and a plurality of energy storage modules, and the plurality of energy storage modules are mounted on the cluster frame. The cluster frame generally includes a support frame and a guide rail, and the guide rail is arranged on the cluster frame. However, currently, the energy storage module is easy to move after being assembled on the cluster frame. Summary of the invention

[0003] The embodiments of the present application provide a cluster rack, an energy storage device and an electrical device, which can limit the position of the energy storage module to prevent the energy storage module from moving on the cluster rack.

[0004] In the first aspect, an embodiment of the present application provides a cluster frame. The cluster frame includes a support frame and at least one set of guide rail assemblies. The at least one set of guide rail assemblies is fixed on the support frame, and the guide rail assembly includes two guide rails spaced apart along a first direction, and the two guide rails and the support frame form an installation space for installing an energy storage module, and at least one of the two guide rails includes a bearing portion, a limiting portion and a spring structure, the bearing portion extends along a second direction, the bearing portion is used to bear the energy storage module, the limiting portion is fixedly connected to one side of the bearing portion along the first direction, and the spring structure is fixedly connected to the limiting portion at one end in the second direction, and the limiting portion can abut against the energy storage module, and the other end of the spring structure in the second direction is a free end, and the spring structure is used to abut against the energy storage module.

[0005] In the cluster rack provided in the present application, the guide rail assembly is fixed on the support frame and can be used to carry the energy storage module. The guide rail assembly includes at least one guide rail, and the guide rail and the support frame form an installation space for installing the energy storage module. The guide rail includes a bearing portion, a limiting portion and a spring structure. Specifically, the bearing portion is used to carry the energy storage module. The guide rail assembly may include a guide rail in the present application and an ordinary guide rail, and the energy storage module can be limited in the first direction by the guide rail assembly to prevent the energy storage module from moving in the first direction. The spring structure is connected to the limiting portion at one end in the second direction, and the other end in the second direction is a free end. The spring structure is used to abut against the energy storage module, and the energy storage module can be limited in the second direction to prevent the energy storage module from moving in the second direction.

[0006] In a possible implementation, the guide rail assembly includes two guide rails spaced apart along the first direction.

[0007] In the cluster frame provided in the present application, the guide rail assembly includes two guide rails spaced apart along the first direction, which can make the structure more symmetrical and stable.

[0008] In a possible embodiment, the spring structure includes a protruding portion and a free portion connected along the second direction, the protruding portion is fixedly connected to the limiting portion, the protruding portion protrudes from the limiting portion toward the installation space, the protruding portion is used to abut against the energy storage module, and the free portion is a free end.

[0009] In the cluster frame provided by the present application, the protruding portion of the spring structure abuts against the energy storage module, which can play a role in fixing the energy storage module. When the energy storage module is installed on the guide rail, the protruding portion will abut against the energy storage module, and the free end can be squeezed in the opposite direction of the protruding direction, thereby reducing the pressure of the protruding portion on the energy storage module when installing the energy storage module, so that the energy storage module can be successfully installed on the guide rail.

[0010] In a possible implementation, the protruding portion includes a first guide portion and an abutment portion connected along the second direction, the first guide portion is connected between the limiting portion and the abutment portion, and the abutment portion is used to abut against the energy storage module.

[0011] In the cluster frame provided in the present application, the first guide portion is connected between the limiting portion and the abutting portion. When installing the energy storage module, after one end of the energy storage module passes through the limiting portion, the energy storage module is guided to the abutting portion via the first guide portion.

[0012] In a possible implementation manner, the protruding portion further includes a second guide portion, and the second guide portion is connected between the abutting portion and the free portion.

[0013] In the cluster frame provided in the present application, the second guide portion is connected between the abutment portion and the free portion. When installing the energy storage module, one end of the energy storage module can be guided to the free portion via the second guide portion after passing through the abutment portion.

[0014] In a possible implementation manner, a surface of the first guide portion along the first direction facing the energy storage module is an inclined surface.

[0015] In the cluster rack provided in the present application, the first guide portion is an inclined surface. When installing the energy storage module, after one end of the energy storage module passes through the limiting portion, the energy storage module can be more easily guided to the abutting portion via the first guide portion, making it easier to install the energy storage module.

[0016] In a possible implementation manner, the acute angle formed by the first guide portion and the limiting portion is in the range of [10°, 30°].

[0017] In the cluster rack provided in the present application, if the acute angle formed by the first guide portion and the limiting portion is less than 10°, the limiting effect will be lost due to the acute angle formed by the first guide portion and the limiting portion being too small. If the acute angle formed by the first guide portion and the limiting portion is greater than 30°, the acute angle formed by the first guide portion and the limiting portion is too large, which will hinder the energy storage module from being pushed into the installation space, thereby resulting in failure to successfully install the energy storage module on the guide rail. Therefore, the angle range of the acute angle formed by the first guide portion and the limiting portion is [10°, 30°], which can avoid the situation where the limiting effect is lost due to the acute angle formed by the first guide portion and the limiting portion being too small, and can avoid the situation where the energy storage module is hindered from being pushed into the installation space due to the acute angle formed by the first guide portion and the limiting portion being too large, thereby resulting in failure to successfully install the energy storage module on the guide rail.

[0018] In a possible implementation, the limiting portion includes: A first plate body, bent and connected to a side of the bearing portion away from the installation space in the first direction; A second plate body, bent and connected to a side of the first plate body away from the bearing portion; The third plate is bent and connected to a side of the second plate away from the first plate. The third plate is located on a side of the first plate facing the installation space. The protruding portion is fixedly connected to the third plate.

[0019] In the cluster frame provided in the present application, the first plate body is bent and connected to the side of the bearing part away from the installation space in the first direction, the second plate body is bent and connected to the side of the first plate body away from the bearing part, and the third plate body is bent and connected to the side of the second plate body away from the first plate body, so that the guide rail has a "J" shape structure, which makes the guide rail structure stronger.

[0020] In a possible implementation manner, a vertical distance range between the abutting portion and the third plate in the first direction is [2 mm, 5 mm].

[0021] In the cluster frame provided by the present application, if the vertical distance between the abutting portion and the third plate body in the first direction is less than 2mm, the limiting effect will be lost due to the small range of the vertical distance between the abutting portion and the third plate body in the first direction. If the vertical distance between the abutting portion and the third plate body in the first direction is greater than 5mm, the energy storage module cannot be successfully installed on the guide rail because the vertical distance range between the abutting portion and the third plate body in the first direction is too large and occupies too much installation space in the first direction. The vertical distance range between the abutting portion and the third plate body in the first direction is [2mm, 5mm], which can avoid the situation where the limiting effect is lost due to the small range of the vertical distance between the abutting portion and the third plate body in the first direction, and can avoid the situation where the energy storage module cannot be successfully installed on the guide rail because the vertical distance range between the abutting portion and the third plate body in the first direction is too large and occupies too much installation space in the first direction.

[0022] In a possible implementation, the spring structure is located at one end of the guide rail in the second direction, and one end of the guide rail away from the spring structure forms an opening of the installation space with the support frame, and the opening is used for loading the energy storage module.

[0023] In the cluster frame provided in the present application, compared with installing the energy storage module from the end of the guide rail close to the spring structure, installing the energy storage module from the end of the guide rail away from the spring structure and the opening of the support frame to form an installation space is free from the obstruction of the free end, and the installation of the energy storage module is more convenient.

[0024] In a second aspect, an embodiment of the present application provides an energy storage device, the energy storage device comprising at least one energy storage module and the cluster rack as described in the first aspect, wherein the energy storage module is mounted on a guide rail of the cluster rack.

[0025] In the energy storage device provided in the present application, the guide rail assembly is fixed on the support frame and can be used to carry the energy storage module. The guide rail assembly includes at least one guide rail, and the guide rail and the support frame form an installation space for installing the energy storage module.

The guide rail assembly may include a guide rail in the present application and an ordinary guide rail, and the guide rail assembly can be used to limit the energy storage module in the first direction to prevent the energy storage module from moving in the first direction. The spring structure is connected to the limiting portion at one end in the second direction, and the other end in the second direction is a free end. The spring structure is used to abut against the energy storage module, and can limit the energy storage module in the second direction to prevent the energy storage module from moving in the second direction.

[0026] In a possible implementation, a supporting portion is provided on an outer wall of the energy storage module, the spring sheet structure is at least partially accommodated in the supporting portion, and the spring sheet structure is supported against an inner wall of the supporting portion.

[0027] In the energy storage device provided in the present application, a supporting portion is provided on the outer wall of the energy storage module, so that at least part of the spring structure can be accommodated in the supporting portion, for example, the protruding portion is supported by the inner wall of the supporting portion, thereby fixing the energy storage module in the second direction.

[0028] In a third aspect, an embodiment of the present application provides an electrical device, the electrical device comprising the energy storage device as described in the second aspect.

[0029] In the electrical equipment provided in the present application, the guide rail assembly is fixed on the support frame and can be used to carry the energy storage module.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] The following descriptions of the various embodiments are made with reference to the attached drawings to illustrate specific embodiments that may be implemented in the present application. Directional terms mentioned herein, such as "upper", "lower", "front", "back", "left", "right", "inner", "outer", "side", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are intended to better and more clearly describe and understand the present application, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0035] In addition, the serial numbers assigned to the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] Since the energy people need is highly temporal and spatial, in order to rationally utilize energy and improve energy utilization, it is necessary to use a medium or device to store one form of energy in the same form or convert it into another form of energy, and then release it in a specific form of energy based on future application needs. As we all know, the main way to generate green electricity is to develop green energy such as photovoltaics and wind power to replace fossil energy. At present, the generation of green electricity generally relies on photovoltaics, wind power, water potential, etc., while wind and solar energy generally have problems of strong intermittency and large volatility, which will cause instability of the power grid, insufficient electricity during peak hours, too much electricity during low hours, and unstable voltage will also cause damage to electricity. Therefore, it may cause "wind and light abandonment" problems due to insufficient electricity demand or insufficient grid acceptance capacity. To solve these problems, energy storage must be relied on. That is, electrical energy is converted into other forms of energy by physical or chemical means and stored, and energy is converted into electrical energy and released when needed. In simple terms, energy storage is similar to a large "power bank". When photovoltaic and wind energy are sufficient, electrical energy is stored and the stored electricity is released when needed.

[0037] Taking electrochemical energy storage as an example, this solution provides an energy storage device 1000, which is equipped with a chemical battery. The chemical elements in the chemical battery are mainly used as energy storage media. The charging and discharging process is accompanied by chemical reactions or changes in the energy storage medium. Simply put, the electricity generated by wind energy and solar energy is stored in the chemical battery. When the use of external electricity reaches a peak, the stored electricity is released for use, or transferred to places where electricity is scarce for use.

[0038] At present, energy storage (i.e., energy storage) has a wide range of application scenarios, including power generation side energy storage, grid side energy storage, renewable energy grid-connected energy storage, and user side energy storage. The corresponding types of energy storage devices 1000 include: (1) Large energy storage containers used in grid-side energy storage scenarios can serve as high-quality active and reactive power regulation power sources in the grid, achieve load matching of electric energy in time and space, enhance the ability to absorb renewable energy, and are of great significance in grid system backup, relieving peak load power supply pressure, and peak and frequency regulation; (2) The main operating mode of small and medium-sized energy storage cabinets used in industrial and commercial energy storage scenarios (banks, shopping malls, etc.) on the user side and small household energy storage boxes used in home energy storage scenarios on the user side is "peak shaving and valley filling". Since there is a large price difference in electricity charges at peak and valley locations according to electricity demand, after users have energy storage equipment, in order to reduce costs, they usually charge the energy storage cabinets / boxes during the low electricity price period; during the peak electricity price period, the electricity in the energy storage equipment is discharged for use to achieve the purpose of saving electricity bills. In addition, in remote areas and areas prone to natural disasters such as earthquakes and hurricanes, the existence of household energy storage devices is equivalent to users providing themselves and the power grid with backup power, eliminating the inconvenience caused by frequent power outages due to disasters or other reasons.

[0039] The present application embodiment takes the household energy storage scenario in the user-side energy storage as an example to illustrate. Figure 1 This is a schematic diagram of a scenario of an energy storage device 1000 provided in an embodiment of the present application. The energy storage device 1000 of the present application is not limited to a household energy storage scenario.

[0040] like Figure 1 As shown, the present application provides a household energy storage system, which includes an electric energy conversion device (photovoltaic panel 2000), a user load (street lamp 3000a), a user load (household appliance 3000b), etc. and an energy storage device 1000, which is a small energy storage box that can be mounted on an outdoor wall by wall hanging. Specifically, the photovoltaic panel 2000 can convert solar energy into electric energy during the period of low electricity prices, and the energy storage device 1000 is used to store the electric energy and supply it to electrical equipment such as street lamps 3000a and household appliances 3000b for use during peak electricity prices, or to supply power when the power grid is out of power / power outage.

[0041] It is understandable that the energy storage device 1000 may include but is not limited to a single cell, a battery module, a battery pack, a battery system, etc. When the energy storage device 1000 is a single cell, it may be a square battery.

[0042] Please also read Figure 2 , Figure 3 and Figure 4 . Figure 2 A schematic diagram of the structure of an energy storage device 1000 provided in one embodiment of the present application. Figure 3 A schematic structural diagram of a cluster frame 20 provided in one embodiment of the present application. Figure 4 A schematic structural diagram of a guide rail 220 provided in one embodiment of the present application.

[0043] The energy storage device 1000 includes at least one energy storage module 10 and a cluster frame 20. The energy storage module 10 is installed on a guide rail 220 of the cluster frame 20. The cluster frame 20 includes a support frame 21 and at least one set of guide rail assemblies 22. The guide rail assembly 22 is fixed to the support frame 21, and the guide rail assembly 22 includes two guide rails 220 arranged at intervals along a first direction. The two guide rails 220 and the support frame 21 form an installation space 30 for installing the energy storage module 10. At least one of the two guide rails 220 includes a bearing portion 221, a limiting portion 222 and a spring structure 223. The bearing portion 221 extends along a second direction Y, and the bearing portion 221 is used to bear the energy storage module 10. The limiting portion 222 is fixedly connected to the bearing portion 221 on one side of the first direction X. The limiting portion 222 can resist the energy storage module 10. The spring structure 223 is fixedly connected to the limiting portion 222 at one end in the second direction Y. The other end of the spring structure 223 in the second direction Y is a free end 2234 . The spring structure 223 is used to abut against the energy storage module 10 .

[0044] The energy storage device 1000 generally includes a cluster frame 20 and a plurality of energy storage modules 10, and the plurality of energy storage modules 10 are mounted on the cluster frame 20. The cluster frame 20 generally includes a support frame 21 and a guide rail 220, and the guide rail 220 is arranged on the frame of the cluster frame 20. However, currently, the energy storage module is easily moved after being assembled on the cluster frame.

[0045] In the energy storage device 1000 and cluster frame 20 of the present application, the guide rail assembly 22 is fixed on the support frame 21 and can be used to carry the energy storage module 10. The guide rail assembly 22 includes two guide rails 220 arranged at intervals along the first direction X, and the two guide rails 220 and the support frame 21 form an installation space 30 for installing the energy storage module 10. Each guide rail 220 includes a bearing portion 221, a limiting portion 222 and a spring structure 223. Specifically, the bearing portion 221 can be used to carry the energy storage module 10. In a possible embodiment, the guide rail assembly 22 may include a guide rail 220 in the present application arranged at intervals along the first direction X and a common guide rail without a spring structure 223. A guide rail 220 in the present application arranged at intervals along the first direction X and a common guide rail without a spring structure 223 form an installation space 30 for installing the energy storage module 10 with the support frame 21. The movement of the energy storage module 10 in the first direction X can be limited by the guide rail assembly 22 to prevent the energy storage module 10 from moving in the first direction X, thereby achieving the limitation of the energy storage module 10 in the first direction X. The guide rail assembly 22 may also include two guide rails 220 in the present application. The limiting portion 222 can support the energy storage module 10. The spring structure 223 is fixedly connected to the limiting portion 222 at one end in the second direction Y, and the other end in the second direction Y is a free end 2234. The spring structure 223 is used to support the energy storage module 10, and the energy storage module 10 can be limited in the second direction Y to prevent the energy storage module 10 from moving in the second direction Y.

[0046] In the cluster frame 20, the guide rail assembly 22 can be fixed to the support frame 21 by welding, screw fixing, riveting and other connection methods. The guide rail assembly 22 includes two guide rails 220 arranged at intervals along the first direction X. Among them, the first direction X can be the width direction of the bearing portion 221. The interval between the two guide rails 220 and the support frame 21 form an installation space 30 in which the energy storage module 10 can be carried by the bearing portion 221 of the guide rail 220. Among them, the bearing portion 221 extends along a second direction Y different from the first direction X. The second direction Y can be the length direction of the bearing portion 221. The bearing portion 221 includes a first end in the first direction X. The limiting portion 222 is fixedly connected to one side of the bearing portion 221, and specifically can be fixedly connected to the first end of the bearing portion 221. The bearing portion 221 and the limiting portion 222 can be fixedly connected by welding, screw fixing, riveting and other connection methods. In addition, the bearing portion 221 and the limiting portion 222 can also be an integrally formed structure. The spring sheet structure 223 is fixedly connected to the limiting portion 222 at one end in the second direction Y. The spring sheet structure 223 and the limiting portion 222 can be fixedly connected by welding, screw fixing, riveting, etc. The other end of the spring sheet structure 223 that is not fixedly connected to the limiting portion 222 in the second direction Y is a free end 2234.

[0047] The cluster frame 20 can be made of metal materials such as aluminum, steel, or metal alloys, or can be made of non-metal materials such as wood and plastic. The material of the support frame 21 can be the same as that of the cluster frame 20, and this application does not impose any restrictions on this.

[0048] Please also read Figure 5 as well as Figure 6 , Figure 5 A schematic structural diagram of a spring structure provided in one embodiment of the present application. Figure 6 A top view of a spring structure provided in one embodiment of the present application.

[0049] In a possible embodiment, the spring structure 223 includes a protruding portion 2230 and a free portion connected along the second direction Y, the protruding portion 2230 is fixedly connected to the limiting portion 222, the protruding portion 2230 protrudes from the limiting portion 222 toward the installation space 30, the protruding portion 2230 is used to abut against the energy storage module 10, and the free portion is a free end 2234.

[0050] To ensure that the energy storage module 10 can be successfully installed on the guide rail 220, the length of the energy storage module 10 in the first direction X should not be greater than the vertical distance between the two limiting portions 222 of the two guide rails 220 in the first direction X, so as to prevent the energy storage module 10 from being too long in the first direction X or the vertical distance between the two limiting portions 222 of the two guide rails 220 in the first direction X being too small, resulting in the failure to successfully load the energy storage module 10 into the installation space 30. Also, the length of the energy storage module 10 in the first direction X should not be less than the shortest distance between the two bearing portions 221 of the two guide rails 220, so as to prevent the energy storage module 10 from being too short in the first direction X or the shortest distance between the two bearing portions 221 of the two guide rails 220 being too long, resulting in the failure to load the energy storage module 10 on the bearing portion 221. The protruding portion 2230 is fixedly connected to the limiting portion 222 in the second direction Y, and the protruding portion 2230 protrudes from the limiting portion 222 in the first direction X toward the installation space 30 formed by the guide rail 220 and the support frame 21. Therefore, the installation space 30 for installing the energy storage module 10 is squeezed. Thus, the energy storage module 10 installed in the installation space 30 can be abutted against the protruding portion 2230. The free end 2234 is not connected to other components. Therefore, when the energy storage module 10 is installed on the guide rail 220 and the protruding portion 2230 abuts against the energy storage module 10, the free end 2234 is squeezed in the opposite direction of the protruding direction (i.e., away from the installation space 30 in the first direction X), thereby reducing the pressure of the protruding portion 2230 on the energy storage module 10 when installing the energy storage module 10, so that the energy storage module 10 is successfully installed on the guide rail 220.

[0051] It can be seen that the protruding portion 2230 of the spring structure 223 abuts against the energy storage module 10, and can play a role in fixing the energy storage module 10. When the energy storage module 10 is installed on the guide rail 220, the protruding portion 2230 will abut against the energy storage module 10, and the free end 2234 can be squeezed in the opposite direction of the protruding direction, thereby reducing the pressure of the protruding portion 2230 on the energy storage module 10 when installing the energy storage module 10, so that the energy storage module 10 can be successfully installed on the guide rail 220.

[0052] In a possible implementation, the protruding portion 2230 includes a first guide portion 2231 and an abutting portion 2232 connected along the second direction Y, the first guide portion 2231 is connected between the limiting portion 222 and the abutting portion 2232 , and the abutting portion 2232 is used to abut the energy storage module 10 .

[0053] The first guide portion 2231 is connected between the limiting portion 222 and the abutting portion 2232, so when the energy storage module 10 is installed on the guide rail 220 along the second direction Y, the energy storage module 10 first passes through the limiting portion 222 in the second direction Y, and then the energy storage module 10 can be guided to the abutting portion 2232 via the first guide portion 2231. When the energy storage module 10 is removed from the guide rail 220 along the second direction Y, the energy storage module 10 first passes through the abutting portion 2232 in the second direction Y, and then the energy storage module 10 is guided to the limiting portion 222 via the first guide portion 2231.

[0054] In a possible implementation manner, the protruding portion 2230 further includes a second guide portion 2233 , and the second guide portion 2233 is connected between the abutting portion 2232 and the free portion.

[0055] The second guide portion 2233 is connected between the abutment portion 2232 and the free portion, so when the energy storage module 10 is installed on the guide rail 220 along the second direction Y, the energy storage module 10 first passes through the abutment portion 2232 in the second direction Y, and then the energy storage module 10 can be guided to the free portion via the second guide portion 2233. When the energy storage module 10 is removed from the guide rail 220 along the second direction Y, the energy storage module 10 first passes through the free portion in the second direction Y, and then the energy storage module 10 is guided to the abutment portion 2232 via the second guide portion 2233.

[0056] In a possible implementation manner, a surface of the first guide portion 2231 along the first direction X facing the energy storage module 10 is an inclined surface.

[0057] Since the protruding portion 2230 is protruding toward the installation space 30 , the inclined surface of the first guide portion 2231 along the first direction X toward the energy storage module 10 is the inclined surface inclined from the limiting portion 222 toward the installation space 30 in the second direction Y.

[0058] The first guide portion 2231 is an inclined surface. When installing the energy storage module 10, after one end of the energy storage module 10 passes through the limiting portion 222, the energy storage module 10 can be more easily guided to the abutting portion 2232 via the first guide portion 2231, making it easier to install the energy storage module 10 in the cluster frame 20.

[0059] In a possible implementation manner, the acute angle formed by the first guide portion 2231 and the limiting portion 222 is in the range of [10°, 30°].

[0060] For example, the acute angle formed by the first guide portion 2231 and the limiting portion 222 may be 10°, 12°, 15°, 19°, 26°, 30°, etc., which are within the range of [10°, 30°] and are not listed here one by one. Figure 6 In the top view of the spring structure 223 shown, the direction indicated by the dotted line is the extension direction of the limiting portion 222, and the angle of the acute angle α formed by the first guide portion 2231 and the limiting portion 222, that is, the angle of the acute angle α formed by the dotted line and the first guide portion 2231 is 25°. It should be noted that the angle of the acute angle formed by the first guide portion 2231 and the limiting portion 222, and the angle of the acute angle formed by the second guide portion 2233 and the limiting portion 222 can be the same or different, and the embodiment of the present application does not limit this.

[0061] If the acute angle formed by the first guide portion 2231 and the limiting portion 222 is less than 10°, the limiting effect will be lost due to the acute angle formed by the first guide portion 2231 and the limiting portion 222 being too small. If the acute angle formed by the first guide portion 2231 and the limiting portion 222 is greater than 30°, the energy storage module 10 will be blocked from being pushed into the installation space 30 due to the acute angle formed by the first guide portion 2231 and the limiting portion 222 being too large, resulting in failure to successfully install the energy storage module 10 on the guide rail 220. Therefore, the angle range of the acute angle formed by the first guide portion 2231 and the limiting portion 222 is [10°, 30°], which can avoid the situation where the limiting effect is lost due to the acute angle formed by the first guide portion 2231 and the limiting portion 222 being too small, and can also avoid the situation where the energy storage module 10 cannot be successfully installed on the guide rail 220 due to the acute angle formed by the first guide portion 2231 and the limiting portion 222 being too large, thereby hindering the energy storage module 10 from being pushed into the installation space 30.

[0062] In one possible implementation, please refer again to Figure 4 The limiting portion 222 includes a first plate 2221, a second plate 2222 and a third plate 2223, wherein: The first plate body 2221 is bent and connected to the side of the bearing part 221 away from the installation space 30 in the first direction X; the second plate body 2222 is bent and connected to the side of the first plate body 2221 away from the bearing part 221; the third plate body 2223 is bent and connected to the side of the second plate body 2222 away from the first plate body 2221, and the third plate body 2223 is located on the side of the first plate body 2221 facing the installation space 30, and the protruding portion 2230 is fixedly connected to the third plate body 2223.

[0063] The first plate 2221 is bent and connected to the side of the bearing part 221 away from the installation space 30 in the first direction X, and the first plate 2221 extends along the second direction Y. The second plate 2222 is bent and connected to the side of the first plate 2221 away from the bearing part 221, and the second plate 2222 extends along the second direction Y. In other words, the two ends of the first plate 2221 in the width direction (third direction Z) of the first plate 2221 are bent and connected to the bearing part 221 and the second plate 2222 respectively. The third plate 2223 is bent and connected to the side of the second plate 2222 away from the first plate 2221, and the third plate 2223 extends along the second direction Y. In other words, the two ends of the second plate 2222 in the width direction (first direction X) of the second plate 2222 are bent and connected to the first plate 2221 and the third plate 2223 respectively. Among them, the third plate 2223 is located on the side of the first plate 2221 facing the installation space 30 in the first direction X. The third plate 2223 can be located on the side of the second plate 2222 facing the bearing portion 221, or on the side of the second plate 2222 facing away from the bearing portion 221 in the third direction Z. The first plate 2221 and the second plate 2222, and / or the second plate 2222 and the third plate 2223, can be bent and connected by welding, screw fixing, riveting, etc. In addition, the first plate 2221 and the second plate 2222, and / or the second plate 2222 and the third plate 2223, can also be an integrally formed structure.

[0064] In the cluster frame 20 provided in the present application, the first plate body 2221 is bent and connected to the bearing portion 221, the second plate body 2222 is bent and connected to the side of the first plate body 2221 away from the bearing portion 221, and the third plate body 2223 is bent and connected to the side of the second plate body 2222 away from the first plate body 2221, so that the guide rail 220 has a "J" shape structure, which makes the structural strength of the guide rail 220 higher.

[0065] Furthermore, the second plate 2222 and the third plate 2223 are shorter in length in the second direction Y than the first plate 2221, which facilitates processing and molding. The third plate 2223 is mainly used to limit the energy storage module 10 in the second direction Y. The third plate 2223 is shorter in width in the third direction Z than the first plate 2221 and the second plate 2222, which can reduce the weight of the guide rail 220.

[0066] In a possible implementation manner, a vertical distance between the abutting portion 2232 and the third plate body 2223 in the first direction X is in a range of [2 mm, 5 mm].

[0067] For example, the vertical distance between the abutting portion 2232 and the third plate 2223 in the first direction X can be 2 mm, 2.5 mm, 3 mm, 4.4 mm, 5 mm, etc., which are within the range of [2 mm, 5 mm] and are not listed here one by one. Figure 6 In the top view of the spring structure shown in FIG. 1 , the vertical distance between the abutting portion 2232 and the third plate 2223 in the first direction X is represented as h, and the value range of h is [2 mm, 5 mm]. Figure 6 , the vertical distance h between the abutment 2232 and the third plate 2223 in the first direction X is 3.5 mm. If the thickness of the abutment is taken into account, the vertical distance h between the abutment 2232 and the third plate 2223 in the first direction X may refer to the shortest vertical distance between the abutment 2232 and the third plate 2223 in the first direction X, or may refer to the longest vertical distance between the abutment 2232 and the third plate 2223 in the first direction X, or may refer to the average of the shortest vertical distance and the longest vertical distance between the abutment 2232 and the third plate 2223 in the first direction X, and the embodiments of the present application do not limit this. If the thickness of the abutment is taken into account, Figure 6 The vertical distance h between the abutting portion 2232 and the third plate body 2223 in the first direction X shown in FIG. 2 refers to the longest vertical distance between the abutting portion 2232 and the third plate body 2223 in the first direction X.

[0068] If the vertical distance between the abutting portion 2232 and the third plate 2223 in the first direction X is less than 2 mm, the limiting function will be lost because the vertical distance range between the abutting portion 2232 and the third plate 2223 in the first direction X is too small. If the vertical distance between the abutting portion 2232 and the third plate 2223 in the first direction X is greater than 5 mm, the energy storage module 10 cannot be successfully installed on the guide rail 220 because the vertical distance range between the abutting portion 2232 and the third plate 2223 in the first direction X is too large and occupies too much installation space 30 in the first direction X. The vertical distance range between the abutment portion 2232 and the third plate body 2223 in the first direction X is [2mm, 5mm], which can avoid the situation where the limiting effect is lost due to the vertical distance range between the abutment portion 2232 and the third plate body 2223 in the first direction X being too small, and can also avoid the situation where the energy storage module 10 cannot be successfully installed on the guide rail 220 due to the vertical distance range between the abutment portion 2232 and the third plate body 2223 in the first direction X being too large and occupying too much installation space 30 in the first direction X.

[0069] In a possible implementation manner, the spring structure 223 is located at one end of the guide rail 220 in the second direction Y, and the end of the guide rail 220 away from the spring structure 223 forms an opening 40 of the installation space 30 with the support frame 21 (such as Figure 3 As shown in FIG. 1 ), the opening 40 is used for inserting the energy storage module 10 .

[0070] In the cluster rack 20 provided in the present application, compared with installing the energy storage module 10 from the end of the guide rail 220 close to the spring structure 223, installing the energy storage module 10 from the end of the guide rail 220 away from the spring structure 223 and the opening 40 forming the installation space 30 with the support frame 21 is free from the obstruction of the free end 2234, and the installation of the energy storage module 10 is more convenient.

[0071] See also Figure 7 , is a schematic diagram of the structure of an energy storage module 10 provided in one embodiment of the present application. In a possible embodiment, a supporting portion 101 is provided on the outer wall 102 of the energy storage module 10, and the spring sheet structure 223 is at least partially accommodated in the supporting portion 101, and the spring sheet structure 223 is supported against the inner wall of the supporting portion 101.

[0072] The abutting portion 101 may be a groove, or an opening provided on the outer wall 102 of the energy storage module 10. Figure 7 The abutting portion 101 shown is a groove.

[0073] In the energy storage device 1000 provided in the present application, a supporting portion 101 is provided on the outer wall 102 of the energy storage module 10, so that at least a portion of the spring structure 223 can be accommodated in the supporting portion 101, for example, the protruding portion 2230 is supported by the inner wall of the supporting portion 101, thereby achieving fixation of the energy storage module 10 in the second direction Y.

[0074] The present application provides an electric device, which includes an energy storage module 10 provided in any embodiment of the present application, and the energy storage module 10 supplies power to the electric device. The electric device may include but is not limited to battery vehicles, electric toys, electric tools, electric vehicles, ships and spacecraft, mobile phones, portable devices, PDAs, laptop computers, etc.

[0075] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
