Description

Technical Field

[0001] This application relates to the field of energy storage technology, specifically to a fixed component, support structure, and energy storage device. Background Technology

[0002] Currently, battery packs in energy storage devices are typically assembled onto container racks using screws and mounting plates. Specifically, the mounting plate has four through holes, and the rack has four corresponding first mounting holes on each side. The battery pack also has four corresponding second mounting holes on each side. During assembly, the battery pack is first placed on the rack, aligning the second mounting holes on the battery pack with the first mounting holes on the rack. Then, the mounting plate is held against the outside of the rack, aligning the through holes on the mounting plate with the first mounting holes on the rack. Finally, screws are threaded through the through holes on the mounting plate and the first mounting holes on the rack, connecting to the second mounting holes on the battery pack, thus securing the battery pack to the rack. Because a mounting plate is required on each side of the battery pack, a total of eight screws are needed to assemble and secure a single battery pack to the container rack. Furthermore, there are no pre-positioned stops during mounting, requiring manual support, making the battery pack assembly process cumbersome and resulting in low assembly efficiency for the energy storage device. Utility Model Content

[0003] In view of the above problems, this application provides a fixed component, a support structure, and an energy storage device.

[0004] Firstly, this application provides a fixing assembly for fixing a component to be fixed in an energy storage device. The fixing assembly includes a mounting bracket, a fixing plate, and a fixing member. The mounting bracket includes a guide rail, which has a first surface and a second surface facing away from each other in a first direction. The first surface is used to support the component to be fixed, and the guide rail has a insertion hole penetrating the first surface and the second surface. The fixing plate includes an insertion portion and limiting portions protruding away from the insertion portion from both sides in a second direction. The insertion portion passes through the insertion hole and has a fixing hole. The fixing hole penetrates the insertion portion in a third direction. In the first direction, the fixing hole is located on the side where the first surface is located, and the limiting portions are located on the side where the second surface is located and abut against the second surface. The first direction, the second direction, and the third direction are mutually perpendicular. The fixing member is used to pass through the fixing hole and the mounting hole on the component to be fixed, so as to fix the insertion portion and the component to be fixed together.

[0005] In the above technical solution, during the assembly of the component to be fixed onto the container, after the component is placed on the first surface of the guide rail, the insertion part of the fixing plate can be inserted through the insertion hole of the guide rail with one hand until the limiting part abuts against the second surface of the guide rail. At this time, the fixing hole is aligned with the mounting hole on the component to be fixed. Then, the fixing part is inserted through the fixing hole and locked into the mounting hole on the component to be fixed with the same hand, thus realizing the installation of the component to be fixed. On the one hand, the abutting design between the limiting part and the guide rail can realize the pre-limiting of the fixing plate, eliminating the need to use an extra hand to hold the fixing plate for fixing, and enabling one-person, one-handed operation. This greatly simplifies the assembly process of the component to be fixed and helps to improve the assembly efficiency of the component to be fixed onto the container. On the other hand, only one fixing hole needs to be set on the fixing plate. During the assembly of the component to be fixed onto the container, only two fixing parts need to pass through the fixing holes on the fixing plates on the left and right sides of the container to fix the component to the container. The number of fixing parts used is reduced from eight to two (one on each side), which greatly saves assembly costs.

[0006] As an optional technical solution of this application, the plug-in part includes a plug-in sub-part and a reinforcing sub-part. The plug-in sub-part is provided with a through hole and the fixing hole. The through hole penetrates the plug-in sub-part along the third direction. The reinforcing sub-part is disposed in the through hole. In the third direction, the reinforcing sub-part protrudes outward relative to the plug-in sub-part toward the outside of the through hole, and the height of the protrusion relative to the plug-in sub-part decreases after being pressed.

[0007] In the above technical solution, when the fixing plate fixes the part to be fixed, the fixing plate will cause the reinforcing part to be squeezed when the fixing part is locked into the mounting hole of the part to be fixed. The reinforcing part is compressed and a reaction force is generated, so that the fixing plate and the side beam of the part to be fixed generate an elastic fixing force, which can prevent the part to be fixed from shaking, and realize the stable fixing of the part to be fixed with one fixing part.

[0008] As an optional technical solution of this application, the reinforcing part is a spring, and at least part of the spring protrudes outward from the through hole to form a contact point. The contact point is used to abut against the part to be fixed. The fixing hole and the limiting part are respectively located on opposite sides of the through hole in the first direction.

[0009] In the above technical solution, when the component to be fixed is fully assembled on the fixing assembly, three fixing forces can be formed. The first force is the fixing force generated when the fixing component passes through the fixing hole and the mounting hole of the component to be fixed. The second force is the fixing force generated when the contact point of the spring contacts against the component to be fixed. The third force is the fixing force formed when the limiting part contacts the second surface of the guide rail. Since the fixing hole and the limiting part are located on opposite sides of the through hole in the first direction, the three positions that generate fixing forces are distributed sequentially along the first direction (the length direction of the plug-in part), which can improve the stability of fixing the component to be fixed.

[0010] As an optional technical solution of this application, the reed includes a first bend and a second bend. One end of the first bend is connected to a first side of the through hole in the first direction, and one end of the second bend is connected to a second side of the through hole in the first direction. The first side and the second side are opposite to each other. The other end of the first bend and the other end of the second bend are connected to form the contact point.

[0011] In the above technical solution, the first bend and the second bend can enhance the elasticity of the spring, strengthen the tightness of the spring in fixing the part to be fixed, prevent the part to be fixed from shaking, reduce the mechanical wear of the spring, and improve the service life of the fixing plate.

[0012] As an optional technical solution of this application, when the component to be fixed is not installed to the mounting bracket, in the third direction, the ratio between the height H of the reinforcing sub-part protruding relative to the plug sub-part and the thickness T of the reinforcing sub-part is greater than or equal to 0.3 and less than or equal to 0.8.

[0013] In the above technical solution, in the third direction, the ratio between the height H of the reinforcing part protruding relative to the plug-in part and the thickness T of the reinforcing part is greater than or equal to 0.3 and less than or equal to 0.8. This not only ensures that the plug-in part itself has sufficient strength to form a stable fixation to the fastener, but also ensures that the elasticity of the reinforcing part is appropriate and can generate sufficient reaction force to strengthen the fixation of the fastener.

[0014] As an optional technical solution of this application, the guide rail includes a main body and a guide part. The main body is used to support the component to be fixed and includes a first end and a second end that are opposite each other in the third direction. The guide part is connected to the first end of the main body. The insertion hole is provided at the connection between the guide part and the main body. The supplementary angle α between the first surface of the main body and the first surface of the guide part is greater than or equal to 20° and less than or equal to 35°.

[0015] In the above technical solution, since the supplementary angle α of the included angle is greater than or equal to 20° and less than or equal to 35°, the downward tilt of the guide portion relative to the main body is appropriate. The component to be fixed does not need to be at a high height in the height direction (first direction) of the energy storage device to be loaded onto the guide rail using the guide portion, without having to overcome a large gravity, and the component to be fixed will not collide with the guide portion. In addition, the component to be fixed can be pushed onto the main body without applying a large force, and the guide portion can play its maximum guiding role. Furthermore, the insertion hole is set at the connection between the guide portion and the main body. When the fixing plate fixes the component to be fixed, the fixing plate will not occupy the space on the main body used to support the component to be fixed, and the component to be fixed will not protrude from the first end of the main body to the outside of the cluster frame, which can prevent the component to be fixed from colliding with other objects in the external environment, thereby ensuring that the component to be fixed is not damaged.

[0016] As an optional technical solution of this application, the limiting part includes an extension sub-part and a limiting sub-part. The extension sub-part extends from the outer side wall of the insertion part in the second direction in a direction away from the insertion part. The limiting sub-part extends from the side of the extension sub-part that is the same as the fixing hole and bends away from the main body part. The limiting sub-part includes a limiting surface that abuts against the guide part. The angle b between the limiting surface and the first direction is greater than or equal to 55° and less than or equal to 70°.

[0017] In the above technical solution, the angle b between the limiting surface and the first direction is greater than or equal to 55° and less than or equal to 70°, which makes the angle between the limiting sub-part and the extension sub-part appropriate, and the slope formed by the limiting sub-part is also appropriate. The limiting sub-part with an appropriate slope and the guide part with an appropriate slope can form a good contact relationship, so that the fixing plate will not slide relative to the guide part, thereby allowing the part to be fixed to be stably fixed.

[0018] As an optional technical solution of this application, the mounting bracket further includes a first limiting part, the guide rail includes a main body part, the main body part is used to carry the component to be fixed, and includes a first end and a second end opposite to each other on the third side, the first limiting part is connected to the second end of the main body part, and includes a first sub-part and a second sub-part, the first sub-part extends from the first surface, the second sub-part bends and extends from the first sub-part toward the fixing plate and is spaced apart from the main body part, the second sub-part is used to restrict the movement of the component to be fixed.

[0019] In the above technical solution, when the fastener is installed on the mounting bracket, the first sub-part can restrict the forward movement of the fastener along a third direction, the second sub-part can restrict the forward movement of the fastener along a first direction, the first surface can restrict the reverse movement of the fastener along the first direction, and the fixing plate can further restrict the reverse movement of the fastener along a third direction, so that the fastener can be stably fixed by the fixing assembly.

[0020] As an optional technical solution of this application, the first sub-part includes a first limiting surface facing the fixed plate, and the second sub-part includes a second limiting surface facing the first surface. The included angle c between the first limiting surface and the second limiting surface is greater than or equal to 85° and less than or equal to 89°.

[0021] In the above technical solution, the included angle c between the first limiting surface and the second limiting surface is greater than or equal to 85° and less than or equal to 89°. The size of the included angle c is appropriate. On the one hand, it can ensure that the second sub-part can be easily inserted into the limiting hole on the part to be fixed. When the part to be fixed is installed on the cluster frame, the end of the part to be fixed (the second end of the main body near the guide rail) can be fixed by blind insertion, ensuring the stable and reliable assembly of the part to be fixed. On the other hand, the second sub-part can effectively restrict the positive movement of the part to be fixed along the first direction.

[0022] As an optional technical solution of this application, the second sub-part includes two side surfaces, an end surface, and two chamfered surfaces. Along the second direction, the two side surfaces are arranged opposite to each other, the end surface is located between the two side surfaces, and each chamfered surface is connected between a side surface and the end surface. The included angle d between the chamfered surface and the side surface is greater than or equal to 45 degrees and less than or equal to 88 degrees.

[0023] In the above technical solution, the included angle d between the chamfered surface and the side surface is greater than or equal to 45 degrees and less than or equal to 88 degrees. Thus, the included angle d is appropriate. On the one hand, the guiding effect of the chamfered surface is obvious when the second part is inserted into the limiting hole on the part to be fixed, and the blind insertion effect is better. On the other hand, the front end of the second part is not sharp, so it will not scratch the fourth surface of the part to be fixed when the second part is inserted into the limiting hole on the part to be fixed, thus ensuring the integrity of the appearance of the part to be fixed.

[0024] As an optional technical solution of this application, the mounting bracket further includes a second limiting part, which is disposed on one side of the main body and extends from the first surface. The second limiting part is used to restrict the movement of the component to be fixed in the second direction.

[0025] In the above technical solution, the first limiting part, the guide rail and the second limiting part together form an installation space. In this installation space, the first sub-part can restrict the forward movement of the member to be fixed along a third direction, the second sub-part can restrict the forward movement of the member to be fixed along a first direction, the first surface can restrict the reverse movement of the member to be fixed along the first direction, the second limiting part can restrict the forward / reverse movement of the member to be fixed along a second direction, and the fixing plate restricts the reverse movement of the member to be fixed along a third direction. In this way, all six degrees of freedom of the member to be fixed are limited, that is, it is stably fixed in the installation space by the fixing components.

[0026] As an optional technical solution of this application, the fixing component includes a first mounting bracket, a second mounting bracket, a first fixing plate, a second fixing plate, a first fixing member, and a second fixing member. In the second direction, the first mounting bracket and the second mounting bracket are spaced apart and arranged opposite to each other. The first fixing plate and the second fixing plate are both used to fix the member to be fixed. The insertion part of the first fixing plate can be inserted into the insertion hole of the first mounting bracket, and the insertion part of the second fixing plate can be inserted into the insertion hole of the second mounting bracket. The first fixing member is used to pass through the fixing hole of the first fixing plate and the first mounting hole of the member to be fixed, and is fixedly connected to the insertion part of the first fixing plate and the member to be fixed. The second fixing member is used to pass through the fixing hole of the second fixing plate and the second mounting hole of the member to be fixed, and is fixedly connected to the insertion part of the second fixing plate and the member to be fixed.

[0027] In the above technical solution, the first mounting bracket and the second mounting bracket are used to support the component to be fixed and to restrict the positive degree of freedom of the component to be fixed in the first direction. The first fixing plate, the second fixing plate, the first fixing member and the second fixing member are used to restrict the other five degrees of freedom of the component to be fixed, thereby ensuring the stable assembly of the component to be fixed.

[0028] Secondly, this application provides a support structure, which includes a cluster frame and a fixing component as described in any of the above embodiments. The cluster frame is provided with an assembly slot, and the mounting bracket of the fixing component is installed in the assembly slot.

[0029] In the aforementioned support structure, during the assembly of the component to be fixed onto the frame, after the component is supported on the first surface of the guide rail, the insertion part of the fixing plate can be inserted through the insertion hole of the guide rail with one hand until the limiting part abuts against the second surface of the guide rail. At this time, the fixing hole is aligned with the mounting hole on the component to be fixed. Then, the same hand is used to insert the fixing part through the fixing hole and lock it into the mounting hole on the component to be fixed, thus realizing the installation of the component to be fixed. On the one hand, the abutting design between the limiting part and the guide rail can realize the pre-limiting of the fixing plate, eliminating the need to use an extra hand to hold the fixing plate for fixing, and enabling one-person, one-handed operation. This greatly simplifies the assembly process of the component to be fixed and helps to improve the assembly efficiency of the component to be fixed onto the container. On the other hand, the number of fixing parts used is reduced from eight to two (one on each side), greatly saving assembly costs.

[0030] As an optional technical solution of this application, there are multiple assembly slots and multiple fixing components, with the mounting bracket of each fixing component installed in one assembly slot. In this way, a single container can assemble multiple components to be fixed, improving the integration of the components.

[0031] Thirdly, this application provides an energy storage device, which includes a support structure and a component to be fixed as described in any of the above embodiments. The component to be fixed is assembled on the guide rail and fixedly connected to the insertion part.

[0032] In the aforementioned energy storage device, during the assembly of the component to be fixed onto the support structure, after the component is supported on the first surface of the guide rail, the insertion part of the fixing plate can be inserted through the insertion hole of the guide rail with one hand until the limiting part abuts against the second surface of the guide rail. At this time, the fixing hole is aligned with the mounting hole on the component to be fixed. Then, the same hand is used to insert the fixing part through the fixing hole and lock it into the mounting hole on the component to be fixed, thus realizing the installation of the component to be fixed. On the one hand, the abutting design between the limiting part and the guide rail can realize the pre-limiting of the fixing plate, eliminating the need to use an extra hand to hold the fixing plate for fixing, and enabling one-person, one-handed operation. This greatly simplifies the assembly process of the component to be fixed and helps to improve the assembly efficiency of the component to be fixed onto the container. On the other hand, the number of fixing parts used is reduced from eight to two (one on each side), greatly saving assembly costs.

[0033] As an optional technical solution of this application, the component to be fixed includes a component body and a roller. The component body is provided with a mounting groove. The opening of the mounting groove is located on the surface of the component to be fixed facing the guide rail. The roller is mounted in the mounting groove and can roll relative to the guide rail within the mounting groove.

[0034] In the above technical solution, the component to be fixed can be installed or removed by the rolling friction between the roller and the first surface of the guide rail. This reduces the manual pressure during the installation and removal of the component, making the whole process convenient and quick, and also avoids the problem of maintenance failure due to the large size of the component to be fixed.

[0035] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0068] Please see Figure 1 and Figure 2, Figure 1 This is a three-dimensional structural diagram of the energy storage device 1000 provided in this application. Figure 2 yes Figure 1 The diagram shows a planar structure of the energy storage device 1000.

[0069] For ease of description, the height direction of the energy storage device 1000 is defined as the Z-axis direction, and is used as the first direction Z; the length direction of the energy storage device 1000 is defined as the X-axis direction, and is used as the second direction X; the width direction of the energy storage device 1000 is defined as the Y-axis direction, and is used as the third direction Y; wherein, the X-axis direction, the Y-axis direction and the Z-axis direction are mutually perpendicular.

[0070] The energy storage device 1000 includes a support structure 100 and a battery pack 200, with the battery pack 200 assembled within the support structure 100. The support structure 100 includes a cluster frame 20 and a fixing assembly 10. The length direction of the cluster frame 20 is the X-axis direction (second direction X), the width direction is the Y-axis direction (third direction Y), and the height direction is the Z-axis direction (first direction Z).

[0071] The cluster frame 20 includes a first side 21 and a second side 23. Along the width direction Y of the cluster frame 20, the first side 21 and the second side 23 are arranged opposite to each other. The cluster frame 20 is provided with a mounting groove 25 for assembling the battery pack 200. Specifically, the opening of the mounting groove 25 is located on the first side 21. The mounting groove 25 is recessed from the first side 21 towards the second side 23 (the width direction Y of the cluster frame 20). The mounting groove 25 includes two groove sidewalls (not shown in the figure), which are spaced apart and arranged opposite to each other along the width direction (the second direction X) of the mounting groove 25.

[0072] In this embodiment, there are multiple assembly slots 25, which form multiple assembly slot groups. These assembly slot groups are arranged sequentially at intervals along the length direction X of the frame 20. Each assembly slot group includes multiple assembly slots 25, which are arranged sequentially along the height direction Z of the support structure 100. For example, the multiple assembly slots 25 form four assembly slot groups, and each assembly slot group includes eight assembly slots 25.

[0073] The fixing component 10 is installed on the two side walls of the assembly slot 25 and is used to fix the component to be fixed. The component to be fixed can be any element that needs to be fixed. When the support structure 100 is applied in the energy storage device 1000, the component to be fixed can be a battery pack 200. When the support structure 100 is applied to other devices, the component to be fixed can also be other types of elements, which are not limited here. This application only uses a battery pack 200 as an example for the component to be fixed. In this embodiment, there are multiple fixing components 10 and multiple battery packs 200. Each fixing component 10 is installed on the side wall of one assembly slot 25 and is used to fix one battery pack 200. Multiple battery packs 200 form multiple battery pack groups, and each battery pack group is assembled in one assembly slot group. Each battery pack group includes multiple battery packs 200, and the multiple battery packs 200 of each battery pack group are respectively assembled in multiple assembly slots 25 of an assembly slot group. For example, multiple battery packs 200 form four battery pack groups, each battery pack group including eight battery packs 200, and the eight battery packs 200 are respectively assembled in eight assembly slots 25.

[0074] Please see Figure 3 and Figure 4 To facilitate the explanation of how the fixing component 10 fixes the battery pack 200, the specific structure of the battery pack 200 will be described below.

[0075] Please refer to the following: Figures 5 to 8 The battery pack 200 includes a battery pack body 40 and rollers 50, with the rollers 50 mounted on the battery pack body 40. The width direction of the battery pack body 40 is the X-axis direction (second direction X), the length direction is the Y-axis direction (third direction Y), and the thickness direction is the Z-axis direction (first direction Z). The battery pack body 40 includes a first surface 401, a second surface 402, a third surface 403, and a fourth surface 404. Along the thickness direction Z of the battery pack body 40, the first surface 401 and the second surface 402 are positioned opposite each other. The third surface 403 and the fourth surface 404 are located between the first surface 401 and the second surface 402, and are positioned opposite each other along the length direction Y of the battery pack body 40.

[0076] The battery pack body 40 is provided with a mounting groove 405, a mounting hole 406, and a limiting hole 407. Along the width direction X of the battery pack body 40, the mounting groove 405, mounting hole 406, and limiting hole 407 are all located on one side of the battery pack body 40. The opening of the mounting groove 405 is located on the second surface 402. The mounting groove 405 is recessed from the second surface 402 towards the first surface 401 (positive Z-axis direction in the figure). There are multiple mounting grooves 405, including first mounting grooves 405a and second mounting grooves 405b. Along the width direction of the battery pack body 40, the first mounting grooves 405a and second mounting grooves 405b are spaced apart. For example, there are multiple first mounting grooves 405a and multiple second mounting grooves 405b. Along the length direction of the battery pack body 40, multiple first mounting grooves 405a are spaced apart, and multiple second mounting grooves 405b are spaced apart.

[0077] The opening of the mounting hole 406 is located on the third surface 403. The mounting hole 406 is recessed from the third surface 403 toward the fourth surface 404 (in the positive Y-axis direction shown in the figure). There are two mounting holes 406, namely the first mounting hole 406a and the second mounting hole 406b, which are arranged alternately along the width direction X of the battery pack body 40.

[0078] The opening of the limiting hole 407 is located on the fourth surface 404. The limiting hole 407 is recessed from the fourth surface 404 toward the third surface 403 (in the negative Y-axis direction shown in the figure). The limiting hole 407 includes an abutment surface 408, which is the inner surface of the limiting hole 407 furthest from the second surface 402, and the distance between the abutment surface 408 and the second surface 402 is L1. In this embodiment, there are two limiting holes 407, namely a first limiting hole 407a and a second limiting hole 407b, which are arranged at intervals along the width direction X of the battery pack body 40.

[0079] In this embodiment, the battery pack body 40 includes a battery housing 41 and two side beams 42. Along the width direction X of the battery housing 41, the two side beams 42 are located on opposite sides of the battery housing 41. Each side beam 42 is provided with a mounting groove 405, a mounting hole 406, and a limiting hole 407. Specifically, the two side beams 42 are a first side beam 42a and a second side beam 42b. The first side beam 42a is provided with a first mounting groove 405a, a first mounting hole 406a, and a first limiting hole 407a, while the second side beam 42b is provided with a second mounting groove 405b, a second mounting hole 406b, and a second limiting hole 407b.

[0080] Rollers 50 are mounted in mounting slots 405 and exposed relative to the battery pack body 40, and can roll relative to the battery pack body 40 about an axis extending along the width direction X of the battery pack body 40. Rollers 50 include first rollers 50a and second rollers 50b. Multiple first rollers 50a (two or more) are mounted in multiple first mounting slots 405a. Multiple second rollers 50b are also mounted in multiple second mounting slots 405b. Each first roller 50a is mounted in one first mounting slot 405a, and each second roller 50b is mounted in one second mounting slot 405b.

[0081] The fixing component 10 will be described in detail below with reference to the accompanying drawings.

[0082] Please see Figure 5 , Figure 6 , Figure 9 and Figure 10 The fixing assembly 10 includes a mounting bracket 11, a fixing plate 13, and a fixing member 15. The mounting bracket 11 includes a guide rail 111, which has a first surface 1111 and a second surface 1112 opposite to each other in the thickness direction Z (first direction Z). The first surface 1111 is used to support the component to be fixed, such as a battery pack 200. The guide rail 111 is provided with a insertion hole 1110 that passes through the first surface 1111 and the second surface 1112. The fixing plate 13 includes a plug-in portion 131 and a limiting portion 133 extending from both sides of the plug-in portion 131 in the second direction X away from the plug-in portion 131. The plug-in portion 131 has a plug-in hole 1110 and a fixing hole 1310. The fixing hole 1310 penetrates the plug-in portion 131 along the thickness direction Y (third direction Y). In the length direction Z (first direction Z) of the plug-in portion 131, the fixing hole 1310 and the limiting portion 133 are located on opposite sides of the guide rail 111. Figure 12 (As shown), the limiting part 133 abuts against the second surface 1112 of the guide rail 111. The fixing member 15 is used to pass through the fixing hole 1310 and the mounting hole 406 on the battery pack 200 to fix the plug-in part 131 and the battery pack 200.

[0083] Mounting bracket 11 is a support structure in fixing assembly 10 for supporting battery pack 200. Mounting bracket 11 is mounted on the side wall of mounting slot 25. Mounting bracket 11 includes a guide rail 111, the length direction of guide rail 111 is the Y-axis direction (third direction Y), the width direction of guide rail 111 is the X-axis direction (second direction X), and the thickness direction (height direction) of guide rail 111 is the Z-axis direction (first direction Z). Guide rail 111 includes a first surface 1111 and a second surface 1112 opposite to each other in the thickness direction Z. When battery pack 200 is mounted on mounting bracket 11 of fixing assembly 10, battery pack 200 is supported on the first surface 1111. Guide rail 111 has a insertion hole 1110 penetrating the first surface 1111 and the second surface 1112. In one example, along the length direction Y of guide rail 111, insertion hole 1110 is located at one end of guide rail 111. In addition, the shape of the cross-section (the plane intercepted by the XY plane) of the insertion hole 1110 includes, but is not limited to, a rectangle, a circle, an ellipse, a triangle or other regular or irregular shape, depending on the shape of the cross-section of the fixing plate 13.

[0084] The fixing plate 13 is a structure in the fixing assembly 10 used to fix the battery pack 200 to the mounting bracket 11. The fixing plate 13 includes a plug-in portion 131 and a limiting portion 133. The plug-in portion 131 is a component in the fixing plate 13 for passing through the plug-in hole 1110. The length direction of the plug-in portion 131 is the Z-axis direction (first direction Z), the width direction of the plug-in portion 131 is the X-axis direction (second direction X), and the thickness direction (height direction) of the plug-in portion 131 is the Y-axis direction (third direction Y). In this embodiment, the plug-in portion 131 is a plate-shaped structure and passes through the plug-in hole 1110. That is, a part of the plug-in portion 131 (hereinafter referred to as: the first part) is located on the side where the first surface 1111 of the guide rail 111 is located, and the other part of the plug-in portion 131 (hereinafter referred to as: the second part) is located on the side where the second surface 1112 of the guide rail 111 is located. The first part and the second part are connected and together form a plate-shaped plug-in portion 131. The insertion portion 131 is provided with a fixing hole 1310, which penetrates the insertion portion 131 along the thickness direction Y. The limiting portion 133 is a component used to prevent the insertion portion 131 from dislodging from the side of the insertion hole 1110 near the first surface 1111. Specifically, the limiting portion 133 protrudes from both sides of the insertion portion 131 in the width direction Y, moving away from the insertion portion 131. In the length direction Z of the insertion portion 131, the limiting portion 133 and the fixing hole 1310 are located on opposite sides of the guide rail 111, that is, the fixing hole 1310 is located on the side of the guide rail 111 where the first surface 1111 is located, and the limiting portion 133 is located on the side of the guide rail 111 where the second surface 1112 is located. In other words, the fixing hole 1310 is located in the first part of the insertion portion 131, and the limiting portion 133 is located in the second part of the insertion portion 131. When the battery pack 200 is fully assembled into the fixing component 10, the limiting part 133 abuts against the second surface 1112 of the guide rail 111, thereby preventing the plug-in part 131 from coming out of the plug hole 1110 on the side near the first surface 1111.

[0085] The fastener 15 is a component used to prevent the plug portion 131 from dislodging from the side of the plug hole 1110 near the second surface 1112, and to securely connect the plug portion 131 and the battery pack 200. For example, the fastener 15 may be a screw or bolt. The fastener 15 may pass through the fixing hole 1310 on the plug portion 131 and the mounting hole 406 on the battery pack 200, and be fixedly connected to the fixing plate 13 and the battery pack 200 to secure the battery pack 200, thereby achieving a fixed connection between the battery pack 200 and the bracket structure 100.

[0086] The current mounting plate has four through holes, the cluster frame has four corresponding first mounting holes, and the battery pack has four corresponding second mounting holes. During assembly, screws pass through the through holes on the mounting plate and the first mounting holes on the cluster frame, and then screw into the second mounting holes on the battery pack. Since a mounting plate is required on both the left and right sides of the battery pack, a total of eight screws are needed to assemble and fix a battery pack to the cluster frame of the support structure. Moreover, there are no pre-positioned stops when installing the mounting plates, requiring manual support during installation. This makes the battery pack assembly process cumbersome and the assembly efficiency of the energy storage device low. In this embodiment, during the assembly of the battery pack 200 onto the bracket structure 100, after the battery pack 200 is mounted on the first surface 1111 of the guide rail 111, the insertion portion 131 of the fixing plate 13 can be inserted through the insertion hole 1110 of the guide rail 111 with one hand until the limiting portion 133 abuts against the second surface 1112 of the guide rail 111. At this time, the fixing hole 1310 is aligned with the mounting hole 406 on the battery pack 200. Then, the fixing member 15 is inserted through the fixing hole 1310 and locked onto the battery pack 200 with the same hand. The battery pack 200 can be installed in the mounting hole 406. On the one hand, the abutment design between the limiting part 133 and the guide rail 111 can achieve the pre-limiting of the fixing plate 13, eliminating the need to hold the fixing plate 13 with one hand for fixing. This allows for single-person, one-handed operation, which greatly simplifies the assembly process of the battery pack 200 and helps improve the assembly efficiency of the battery pack 200 on the bracket structure 100. On the other hand, the number of fasteners 15 used is reduced from eight to two (one on each side), which greatly saves assembly costs.

[0087] Please see Figure 10 and Figure 11 As an optional technical solution of this application, the plug-in portion 131 may include a plug-in sub-portion 1311 and a reinforcing sub-portion 1313. The plug-in sub-portion 1311 is provided with a through hole 1312 and a fixing hole 1310. The through hole 1312 penetrates the plug-in sub-portion 1311 along the thickness direction Y. The reinforcing sub-portion 1313 is disposed in the through hole 1312. In the third direction Y, the reinforcing sub-portion 1313 protrudes relative to the plug-in sub-portion 1311 toward the outside of the through hole 1312 (specifically toward the battery pack 200), and the height of the protrusion relative to the plug-in sub-portion 1311 decreases after being pressed.

[0088] The connector 1311 is a component for passing through the connector hole 1110. Specifically, the connector 1311 is provided with a through hole 1312 and a fixing hole 1310. The through hole 1312 penetrates the connector 1311 along the thickness direction Y. The shape of the longitudinal section (the plane intercepted by the XZ plane) of the through hole 1312 is, but is not limited to, a rectangle, a circle, an ellipse, a triangle or other regular or irregular shapes.

[0089] The reinforcing sub-part 1313 is a component used to reinforce the fixation of the battery pack 200 by contacting it. In some embodiments, the reinforcing sub-part 1313 is a micro-elastic body, that is, an elastic body capable of undergoing slight deformation (small deformation amount). The reinforcing sub-part 1313 is disposed in the through hole 1312. When not subjected to external force, the reinforcing sub-part 1313 protrudes relative to the insertion sub-part 1311 towards the battery pack 200, that is, it protrudes in the positive direction of the thickness direction Y of the insertion sub-part 131. When subjected to negative pressure in the thickness direction Y of the insertion sub-part 131, the reinforcing sub-part 1313 undergoes elastic deformation and moves in the negative direction of the thickness direction Y of the insertion sub-part 131, thereby reducing the height H of the protrusion relative to the insertion sub-part 1311.

[0090] In the above technical solution, when the fixing plate 13 fixes the battery pack 200, when the fixing member 15 is tightened (locked into the mounting hole 406 of the battery pack 200), the fixing plate 13 will cause the reinforcing part 1313 to be squeezed against the battery pack 200. The reinforcing part 1313 is compressed and generates a reaction force, so that the fixing plate 13 and the side beam 42 of the battery pack 200 generate an elastic fixing force, which prevents the battery pack 200 from shaking. Thus, the battery pack 200 can be stably fixed by one fixing member 15.

[0091] Please continue reading. Figure 10 and Figure 11 As an optional technical solution of this application, the reinforcing sub-part 1313 is a spring, and at least part of the spring protrudes outward toward the through hole 1312 (specifically toward the battery pack 200) to form a contact 13135. The contact 13135 is used to abut against the battery pack 200. In the length direction Z (first direction Z) of the plug-in sub-part 1311, the fixing hole 1310 and the limiting part 133 are respectively located on opposite sides of the through hole 1312.

[0092] The spring is a component made of elastic metal material, mainly used to provide reliable fixing contact force when the fixing component 10 is mated with the battery pack 200. The main purpose of the spring design is to maintain stable contact with the battery pack 200 through its own elastic deformation, thereby ensuring the stable fixation of the battery pack 200. The shape and design of the spring can be varied as needed, commonly including needle-shaped, perforated, or leaf-shaped, etc. The spring can be a single piece or a combination of multiple pieces. In this application, the reinforcing sub-part 1313 is mainly composed of square springs, which results in less material waste during processing, high production efficiency, and low cost. In addition, the spring is usually made of copper alloy or corrosion-resistant metals such as gold, silver, aluminum, or magnesium to ensure good durability. In this application, the spring has a contact 13135 protruding towards the battery pack 200, which is used to abut against the battery pack 200. This structure ensures the stable fixation of the battery pack 200. In addition, when the battery pack 200 is fully assembled onto the fixing component 10, three fixing forces are generated. The first is the fixing force generated when the fixing member 15 passes through the fixing hole 1310 and the mounting hole 406 of the battery pack 200. The second is the fixing force generated when the contact point 13135 of the spring contacts against the battery pack 200. The third is the fixing force generated when the limiting part 133 contacts the second surface 1112 of the guide rail 111. Since the fixing hole 1310 and the limiting part 133 are located on opposite sides of the through hole 1312 in the length direction Z (first direction Z) of the plug part 1311, the three positions that generate fixing forces are distributed sequentially along the length direction of the plug part 1311, which can improve the stability of fixing the battery pack 200.

[0093] Please continue reading. Figure 10 and Figure 11 As an optional technical solution of this application, the reed includes a first bend 13131 and a second bend 13133. One end of the first bend 13131 is connected to the first side of the through hole 1312, and one end of the second bend 13133 is connected to the second side of the through hole 1312. The first side and the second side of the through hole 1312 are opposite to each other. The other end of the first bend 13131 and the other end of the second bend 13133 are connected to form a contact 13135.

[0094] In one example, the spring is formed by stamping onto the connector portion 1311. That is, the opposite ends of the spring are respectively connected to the opposite sides of the through hole 1312. In this embodiment, the longitudinal section of the through hole 1312 is square. Therefore, the through hole 1312 includes a first side, a second side, a third side, and a fourth side, which are connected end to end in sequence. The first and second sides are the opposite sides of the through hole 1312 in the longitudinal direction Z of the connector portion 1311, and the third and fourth sides are the opposite sides of the through hole 1312 in the width direction X of the connector portion 1311. The opposite ends of the spring can be connected to the first and second sides of the through hole 1312 respectively, or they can be connected to the third and fourth sides of the through hole 1312 respectively. This application only uses the example of the opposite ends of the spring being connected to the first and second sides of the through hole 1312 respectively. One end of the first bend 13131 is connected to the first side of the through hole 1312, one end of the second bend 13133 is connected to the second side of the through hole 1312, and the other end of the first bend 13131 is connected to the other end of the second bend 13133, forming a contact 13135 at the connection. Viewed along the length Z of the connector 1311, the contact 13135 is within the through hole 1312. Viewed along the thickness Y of the connector 1311, the contact 13135 is located between the connector 1311 and the battery pack 200, thus clamping the battery pack 200. Simultaneously, the first bend 13131 and the second bend 13133 enhance the elasticity of the spring, strengthen the spring's grip on the battery pack 200, prevent the battery pack 200 from shaking, reduce mechanical wear of the spring, and improve the service life of the fixing plate 13.

[0095] Please continue reading. Figure 10 and Figure 11 As an optional technical solution of this application, when the battery pack 200 is not installed on the mounting bracket 11, the ratio between the height H of the reinforcing sub-part 1313 protruding relative to the plug sub-part 1311 and the thickness T of the reinforcing sub-part 1313 in the third direction Y is greater than or equal to 0.3 and less than or equal to 0.8.

[0096] In the third direction Y, the ratio between the height H of the reinforcing sub-part 1313 protruding relative to the plug-in sub-part 1311 and the thickness T of the reinforcing sub-part 1313 is greater than or equal to 0.3 and less than or equal to 0.8, that is, H = [0.3 ~ 0.8]T. The ratio between height H and thickness T can be any one of 0.3, 0.4, 0.43, 0.48, 0.5, 0.55, 0.57, 0.6, 0.66, 0.7, 0.76, and 0.8, or any value between any two. When the ratio between height H and thickness T is less than 0.3, the height H is too small relative to the thickness T, the elasticity of the reinforcing sub-part 1313 is insufficient, and it cannot generate enough reaction force to strengthen the fixation of the battery pack 200. When the ratio between height H and thickness T is greater than 0.8, the height H is too large relative to the thickness T. Not only is the strength of the plug part 1311 itself insufficient to form a stable fixation for the battery pack 200, but the elasticity of the reinforcing part 1313 is too large, and it cannot generate enough reaction force to strengthen the fixation of the battery pack 200.

[0097] Therefore, in this embodiment, the ratio between the height H of the reinforcing sub-part 1313 protruding relative to the plug sub-part 1311 and the thickness T of the reinforcing sub-part 1313 is greater than or equal to 0.3 and less than or equal to 0.8. This not only ensures that the plug sub-part 1311 itself has sufficient strength to form a stable fixation for the battery pack 200, but also ensures that the elasticity of the reinforcing sub-part 1313 is appropriate and can generate sufficient reaction force to strengthen the fixation of the battery pack 200.

[0098] Please refer to the following: Figure 6 and Figure 9 As an optional technical solution of this application, the guide rail 111 includes a main body 1113 and a guide part 1115. The main body 1113 is used to carry the battery pack 200 and includes a first end 11131 and a second end 11133 opposite to each other in the length direction Y. The guide part 1115 is connected to the first end 11131 of the main body 1113. The insertion hole 1110 is provided at the connection between the guide part 1115 and the main body 1113. The supplementary angle α between the first surface 1111 of the main body 1113 and the first surface 1111 of the guide part 1115 is greater than or equal to 20° and less than or equal to 35°.

[0099] The guide rail 111 comprises two parts: a main body 1113 for supporting the battery pack 200, and a guide part 1115 for guiding the battery pack 200 from the outside onto the first surface 1111 of the main body 1113. Specifically, the length direction of the main body 1113 is the Y-axis direction (third direction Y), the width direction of the main body 1113 is the X-axis direction (second direction X), and the thickness direction (height direction) of the main body 1113 is the Z-axis direction (first direction Z). Along the length direction Y of the main body 1113, the main body 1113 includes a first end 11131 and a second end 11133. The battery pack 200 is loaded onto the guide rail 111 from the first end 11131; therefore, the guide part 1115 is designed to connect to the first end 11131 of the main body 1113. The supplementary angle α between the first surface 1111 of the main body 1113 and the first surface 1111 of the guide part 1115 has a value greater than or equal to 20° and less than or equal to 35°. That is, the guide part 1115 is inclined downward relative to the main body 1113 to facilitate the loading of the battery pack 200 onto the guide rail 111. The supplementary angle α can be any one of 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34° and 35° or any value between any two. When the supplementary angle α is less than 20°, the downward tilt of the guide portion 1115 relative to the main body 1113 is too small, which is equivalent to a relatively gentle slope. The battery pack 200 still needs to be at a relatively high height in the height direction Z of the energy storage device 1000 in order to be loaded onto the guide rail 111 using the guide portion 1115. The gravity that needs to be overcome is large, and the battery pack 200 is also prone to collision with the guide portion 1115. When the supplementary angle α is greater than 35°, the downward tilt of the guide portion 1115 relative to the main body 1113 is too large. During the process of loading the battery pack 200 onto the guide rail 111 using the guide portion 1115, the slope is relatively steep. A large force needs to be applied to push the battery pack 200 onto the main body 1113, and the guiding effect of the guide portion 1115 is limited.

[0100] Therefore, since the value of the supplementary angle α is greater than or equal to 20° and less than or equal to 35°, the downward tilt of the guide portion 1115 relative to the main body 1113 is appropriate. The battery pack 200 does not need to be at a high height in the height direction Z of the energy storage system 1000 to be loaded onto the guide rail 111 using the guide portion 1115, without having to overcome a large gravity. At the same time, the battery pack 200 will not collide with the guide portion 1115. In addition, the battery pack 200 can be pushed onto the main body 1113 without applying a large force, and the guide portion 1115 can play its maximum guiding role. Furthermore, the insertion hole 1110 is provided at the connection between the guide portion 1115 and the main body portion 1113. When the fixing plate 13 fixes the battery pack 200, the fixing plate 13 will not occupy the space on the main body portion 1113 used to support the battery pack 200, and the battery pack 200 will not protrude from the first end 11131 of the main body portion 1113 to the outside of the cluster frame 20. This can prevent the battery pack 200 from colliding with other objects in the external environment, thereby ensuring that the battery pack 200 is not damaged.

[0101] Please refer to the following: Figures 10 to 12 As an optional technical solution of this application, the limiting part 133 includes an extension sub-part 1331 and a limiting sub-part 1333. The extension sub-part 1331 extends from the outer side wall 1315 of the insertion part 131 in the second direction X in a direction away from the insertion part 131. The limiting sub-part 1333 extends from the side of the extension sub-part 1331 that is the same as the fixing hole 1310 and bends away from the main body part 1113. The limiting sub-part 1333 includes a limiting surface 13331 that abuts against the guide part 1115. The included angle b between the limiting surface 13331 and the length direction Z (first direction Z) of the insertion part 131 is greater than or equal to 55° and less than or equal to 70°.

[0102] The limiting part 133 includes two parts: an extension sub-part 1331, which mainly extends from one side of the insertion part 131 in the width direction X; and a limiting sub-part 1333, which mainly abuts against the guide part 1115 to limit the fixing plate 13 from disengaging from the side where the first surface 1111 of the guide rail 111 is located. The included angle b can be any one of 55°, 56°, 57°, 59°, 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69°, and 70°, or any value between any two. When the included angle b is less than 55°, the included angle between the limiting sub-part 1333 and the extending sub-part 1331 is too small, which means that the slope formed by the limiting sub-part 1333 is relatively steep. It is difficult to form a good contact relationship with the guide part 1115. That is, there may be a gap between the limiting sub-part 1333 and the guide part 1115, which makes it easy for the fixing plate 13 to slide relative to the guide part 1115, thus causing the battery pack 200 to be unstable. When the included angle b is greater than 70°, the included angle between the limiting sub-part 1333 and the extending sub-part 1331 is too large, which means that the slope formed by the limiting sub-part 1333 is relatively gentle. It is also difficult to form a good contact relationship with the guide part 1115 with a suitable slope. That is, there may be a gap between the limiting sub-part 1333 and the guide part 1115, which makes it easy for the fixing plate 13 to slide relative to the guide part 1115, thus causing the battery pack 200 to be unstable. In addition, the included angle b is the angle between the limiting surface 13331 and the length direction Z of the insertion part 131, and the sum of the supplementary angle a of the aforementioned included angle is 90°.

[0103] Therefore, the angle b between the limiting surface 13331 and the insertion part 131 in the length direction Z is greater than or equal to 55° and less than or equal to 70°, which makes the angle between the limiting sub-part 1333 and the extension sub-part 1331 appropriate, and the slope formed by the limiting sub-part 1333 is also appropriate. The limiting sub-part 1333 with an appropriate slope and the guide part 1115 with an appropriate slope can form a good contact relationship, so that the fixing plate 13 will not slide relative to the guide part 1115, thereby allowing the battery pack 200 to be stably fixed.

[0104] Please refer to the following: Figure 6 , Figure 9 , Figure 13 and Figure 14As an optional technical solution of this application, the mounting bracket 11 further includes a first limiting part 113. The guide rail 111 includes a main body 1113 for carrying the battery pack 200. The main body 1113 includes a first end 11131 and a second end 11133 opposite to each other in its length direction Y (third direction Y). The first limiting part 113 is connected to the second end 11133 of the main body 1113 and includes a first sub-part 1131 and a second sub-part 1133. The first sub-part 1131 extends from the first surface 1111, and the second sub-part 1133 bends and extends from the first sub-part 1131 toward the fixing plate 13 and is spaced apart from the main body 1113. The battery pack 200 is provided with a limiting hole 407. When the battery pack 200 is installed on the mounting bracket 11, the second sub-part 1133 is used to insert into the limiting hole 407 and to limit the movement of the battery pack 200.

[0105] The explanation of the main body 1113 is the same as above and will not be repeated here. The first limiting part 113 is a component in the mounting bracket 11 used to limit the positive movement of the battery pack 200 along the length direction Y of the guide rail 111. In some embodiments, the first limiting part 113 and the guide rail 111 can be integrally formed. In other embodiments, the first limiting part 113 and the guide rail 111 can be separately formed, and after the first limiting part 113 and the guide rail 111 are each formed, they are connected together by a certain connection method. The connection method can be a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​or screw-fit, and non-detachable connection methods include, but are not limited to, welding and gluing connections.

[0106] Currently, the battery pack and the end of the cluster frame are not fixed. Since the end (rear end) of the battery pack cannot be operated, the end of the battery pack is not fixed. It can only be limited and fixed by the weight of the battery pack, which leads to unreliable fixation of the battery pack. In this application, the first limiting part 113 includes a first sub-part 1131 and a second sub-part 1133. The first sub-part 1131 extends from the first surface 1111, and the second sub-part 1133 bends and extends from the first sub-part 1131 toward the fixing plate 13 and is spaced apart from the main body 1113. When the battery pack 200 is installed on the mounting frame 11, the second sub-part 1133 is used to insert into the limiting hole 407. Thus, when the battery pack 200 is installed on the mounting bracket 11, a portion of the battery pack 200 will enter the restricted space enclosed by the first sub-part 1131, the second sub-part 1133, and the first surface 1111. Within this restricted space, the first sub-part 1131 can restrict the forward movement of the battery pack 200 along the length direction Y of the guide rail 111, the second sub-part 1133 can restrict the forward movement of the battery pack 200 along the thickness direction Z of the guide rail 111, and the first surface 1111 can restrict the reverse movement of the battery pack 200 along the thickness direction Z of the guide rail 111. In addition, the fixing plate 13 restricts the reverse movement of the battery pack 200 along the length direction Y of the guide rail 111, so the battery pack 200 can be stably fixed by the fixing assembly 10.

[0107] Please refer to the following: Figure 13 ,or Figure 16 and Figure 18 As an optional technical solution of this application, the first sub-part 1131 includes a first limiting surface 11311 facing the fixing plate 13, and the second sub-part 1133 includes a second limiting surface 11331 facing the first surface 1111. The included angle c between the first limiting surface 11311 and the second limiting surface 11331 is greater than or equal to 85° and less than or equal to 89°.

[0108] Specifically, the first limiting surface 11311 and the second limiting surface 11331 are the two inner surfaces of the aforementioned restricted space. When the first limiting surface 11311 and the second limiting surface 11331 are directly connected, the included angle c is the angle between the first limiting surface 11311 and the second limiting surface 11331. When the first limiting surface 11311 and the second limiting surface 11331 are connected by an arc transition, the included angle c is the angle between the extended surface of the first limiting surface 11311 and the extended surface of the second limiting surface 11331. Regardless of the connection method, the included angle c satisfies: 85°≤c≤90°. Specifically, the included angle c can be any one of 85°, 85.5°, 86°, 87°, 87.5°, 87.9°, 88°, 88.3°, 89°, or 90°, or any value between any two. When the included angle c is less than 85°, the included angle c between the first limiting surface 11311 and the second limiting surface 11331 is too small, which is equivalent to the slope formed by the second sub-part 1133 being relatively steep, making it difficult to insert into the limiting hole 407 on the battery pack 200; when the included angle c is greater than 90°, the included angle c between the first limiting surface 11311 and the second limiting surface 11331 is too large, which is equivalent to the slope formed by the second sub-part 1133 being relatively gentle, and the limiting effect on the inner wall of the limiting hole 407 is limited, resulting in the second sub-part 1133 having limited restriction on the positive movement of the battery pack 200 along the thickness direction Z of the guide rail 111.

[0109] Therefore, the included angle c between the first limiting surface 11311 and the second limiting surface 11331 is greater than or equal to 85° and less than or equal to 89°. In this way, the included angle c is appropriate, which on the one hand ensures that the second sub-part 1133 can be easily inserted into the limiting hole 407 on the battery pack 200. When the battery pack 200 is installed on the cluster frame 20, the end of the battery pack 200 (the second end 11133 of the main body 1113 near the guide rail 111) can be fixed by blind insertion, ensuring the stable and reliable assembly of the battery pack 200. On the other hand, the second sub-part 1133 can effectively limit the positive movement of the battery pack 200 along the thickness direction Z of the guide rail 111.

[0110] Please refer to the following: Figure 13 , Figure 14 and Figure 18As an optional technical solution of this application, the second sub-part 1133 also includes a supporting surface 11339 opposite to the second limiting surface 11331. The maximum distance between the supporting surface 11339 and the second surface is L2. The distance L1 between the abutting surface 408 and the second surface 402 is slightly greater than the maximum distance L2 between the supporting surface 11339 and the second surface 402. This allows the supporting surface 11339 to guide the second sub-part 1133 into the limiting hole 407 of the battery pack 200. In this way, the end of the battery pack 200 can be fixed by blind insertion, ensuring the stable and reliable assembly of the battery pack 200.

[0111] Please refer to the following: Figure 13 ,or Figure 16 and Figure 18 As an optional technical solution of this application, the second sub-part 1133 includes two side surfaces 11333, an end surface 11335, and two chamfered surfaces 11337. Along the width direction X (second direction X) of the second sub-part 1133, the two side surfaces 11333 are arranged opposite to each other, the end surface 11335 is located between the two side surfaces 11333, and each chamfered surface 11337 connects one side surface 11333 and the end surface 11335. The included angle d between the chamfered surface 11337 and the side surface 11333 is greater than or equal to 45 degrees and less than or equal to 88 degrees.

[0112] Specifically, the included angle d can be any one of 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55.5°, 56°, 59°, 60°, 63°, 65°, 67°, 70.5°, 77.9°, 80°, 83°, 85.3°, 87°, or 88°, or any value between any two of them. When the included angle d is less than 45°, the included angle between the chamfered surface 11337 and the side surface 11333 is too small, and the chamfer is not obvious. When the second sub-part 1133 is inserted into the limiting hole 407 on the battery pack 200, the guiding effect of the chamfered surface 11337 is not obvious, and the blind insertion effect is not good. When the included angle d is greater than 88°, the chamfer is relatively sharp. When the second sub-part 1133 is inserted into the limiting hole 407 on the battery pack 200, it is easy to scratch the fourth surface 404 of the battery pack 200, resulting in scratches on the fourth surface 404.

[0113] Therefore, the included angle d between the chamfered surface 11337 and the side surface 11333 is greater than or equal to 45 degrees and less than or equal to 88 degrees. In this way, the included angle d is appropriate. On the one hand, when the second sub-part 1133 is inserted into the limiting hole 407 on the battery pack 200, the guiding effect of the chamfered surface 11337 is obvious, and the blind insertion effect is better. On the other hand, the front end of the second sub-part 1133 is not sharp, so when the second sub-part 1133 is inserted into the limiting hole on the battery pack 200, it will not scratch the fourth surface 404 of the battery pack 200, thus ensuring the integrity of the appearance of the battery pack 200.

[0114] Please refer to the following: Figure 6 ,or Figure 13 and Figure 14 As an optional technical solution of this application, the mounting bracket 11 also includes a second limiting part 115. The second limiting part 115 is disposed on one side of the main body part 1113 and extends from the first surface 1111. The second limiting part 115 is used to limit the movement of the battery pack 200 in the width direction X (second direction X).

[0115] The second limiting part 115 is a component in the mounting bracket 11 that at least limits the movement of the battery pack 200 along the width direction X of the guide rail 111. In some embodiments, the second limiting part 115 and the guide rail 111 can be integrally formed. In other embodiments, the second limiting part 115 and the guide rail 111 are separately formed, and after the second limiting part 115 and the guide rail 111 are each formed, they are connected together by a certain connection method. The connection method can be a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​and screw-fit, while non-detachable connection methods include, but are not limited to, welding and gluing. The second limiting part 115 and the first limiting part 113 can be connected or separated. This application takes the separation of the second limiting part 115 and the first limiting part 113 as an example.

[0116] When the battery pack 200 is installed on the mounting bracket 11, a portion of the battery pack 200 will enter the installation space enclosed by the first sub-part 1131, the second sub-part 1133, the first surface 1111, and the second limiting part 115. In this installation space, the first sub-part 1131 can restrict the forward movement of the battery pack 200 along the length direction Y of the guide rail 111, the second sub-part 1133 can restrict the forward movement of the battery pack 200 along the thickness direction Z of the guide rail 111, the first surface 1111 can restrict the reverse movement of the battery pack 200 along the thickness direction Z of the guide rail 111, and the second limiting part 115 can restrict the forward / reverse movement of the battery pack 200 along the width direction X of the guide rail 111. In addition, the fixing plate 13 restricts the reverse movement of the battery pack 200 along the length direction Y of the guide rail 111. Thus, all six degrees of freedom of the battery pack 200 are restricted, i.e., it is stably fixed in the installation space by the fixing component 10.

[0117] Please refer to the following: Figure 5 , Figure 6 , Figure 9 , Figure 10 As an optional technical solution of this application, the fixing assembly 10 includes a first mounting bracket 11a, a second mounting bracket 11b, a first fixing plate 13a, a second fixing plate 13b, a first fixing member 15a, and a second fixing member 15b. Along the width direction X of the fixing assembly 10, the first mounting bracket 11a and the second mounting bracket 11b are spaced apart and arranged opposite to each other. Both the first fixing plate 13a and the second fixing plate 13b are used to fix the battery pack 200. The insertion portion 131 of the first fixing plate 13a can be inserted into the insertion hole 1110 of the first mounting bracket 11a, and the insertion portion 131 of the second fixing plate 13b can be inserted into the insertion hole 1110 of the second mounting bracket 11b. The first fixing member 15a is used to pass through the fixing hole 1310 of the first fixing plate 13a and the first mounting hole 406a of the battery pack 200, and is fixedly connected to the insertion portion 131 of the first fixing plate 13a and the battery pack 200. The second fastener 15b is used to pass through the fixing hole 1310 of the second fixing plate 13b and the second mounting hole 406b of the battery pack 200, and is fixedly connected to the insertion part 131 of the second fixing plate 13b and the battery pack 200.

[0118] In this embodiment, there are two mounting brackets 11, which are respectively mounted on the two side walls of the same assembly slot 25 and used for assembling the battery pack 200. Specifically, the two mounting brackets 11 are spaced apart and arranged opposite each other along the width direction X of the mounting bracket 11. The two mounting brackets 11 are respectively the first mounting bracket 11a and the second mounting bracket 11b. It should be noted that the first mounting bracket 11a and the second mounting bracket 11b have largely the same structure.

[0119] In this embodiment, there are two fixing plates 13, each of which can be inserted into the insertion hole 1110 of a mounting bracket 11. Specifically, the two fixing plates 13 are a first fixing plate 13a and a second fixing plate 13b. The first fixing plate 13a can be inserted into the insertion hole 1110 of the first mounting bracket 11a, and the second fixing plate 13b can be inserted into the insertion hole 1110 of the second mounting bracket 11b. It should be noted that the structures of the first fixing plate 13a and the second fixing plate 13b are largely the same.

[0120] In this embodiment, there are two fasteners 15, namely a first fastener 15a and a second fastener 15b. The first fastener 15a can pass through the fixing hole 1310 of the first fixing plate 13a and the first mounting hole 406a of the battery pack 200, and is fixedly connected to the first fixing plate 13a and the battery pack 200. The second fastener 15b can pass through the fixing hole 1310 of the second fixing plate 13b and the second mounting hole 406b of the battery pack 200, and is fixedly connected to the second fixing plate 13b and the battery pack 200.

[0121] Please combine Figures 15 to 18During the assembly of the battery pack 200 into the bracket structure 100, the battery pack 200 can first be guided by external equipment and the first surface 1111 of the guide part 1115 in the mounting frame 11. The rollers 50 of the battery pack 200 will fall on the first surface 1111 of the guide rail 111. Specifically, the first roller 50a will fall on the first surface 1111 of the guide rail 111 in the first mounting frame 11a, and the second roller 50b will fall on the first surface 1111 of the guide rail 111 in the second mounting frame 11b. Then, under the action of external force, the first roller 50a of the battery pack 200 rolls on the first surface 1111 of the guide rail 111 in the first mounting bracket 11a, and the second roller 50b rolls on the first surface 1111 of the guide rail 111 in the second mounting bracket 11b, until the first limiting part 113 in the first mounting bracket 11a is inserted into the first limiting hole 407a of the battery pack 200, and the first limiting part 113 in the second mounting bracket 11b is inserted into the second limiting hole 407b of the battery pack 200. Next, the insertion part 131 of the fixing plate 13 is inserted into the insertion hole 1110 of the mounting bracket 11. Specifically, the insertion part 131 of the first fixing plate 13a is inserted into the insertion hole 1110 of the first mounting bracket 11a, and the insertion part 131 of the second fixing plate 13b is inserted into the insertion hole 1110 of the second mounting bracket 11b. At this time, the limiting surface 13331 of the limiting part 133 in the fixing plate 13 engages and abuts against the second surface 1112 of the guide part 1115 in the mounting bracket 11. Finally, the fixing member 15 passes through the fixing hole 1310 and is screwed into the mounting hole 406 on the battery pack 200 to fix the battery pack 200 to the fixing assembly 10. Among them, the first fixing member 15a passes through the fixing hole 1310 of the first fixing plate 13a and is screwed into the first mounting hole 406a on the battery pack 200, and the second fixing member 15b passes through the fixing hole 1310 of the second fixing plate 13b and is screwed into the second mounting hole 406b on the battery pack 200.

[0122] In the above technical solution, the fixing component 10 includes a first mounting bracket 11a, a second mounting bracket 11b, a first fixing plate 13a, a second fixing plate 13b, a first fixing member 15a, and a second fixing member 15b. The first mounting bracket 11a and the second mounting bracket 11b are used to support the battery pack 200 and to restrict the positive upward degree of freedom of the battery pack 200 in the height direction Z of the energy storage device 1000. The first fixing plate 13a, the second fixing plate 13b, the first fixing member 15a, and the second fixing member 15b are used to restrict the other five degrees of freedom of the battery pack 200, thereby ensuring the stable assembly of the battery pack 200. In addition, the battery pack 200 can be installed or removed by the rolling friction between the roller 50 and the first surface 1111 of the guide rail 111, which can reduce the manual pressure during the installation and removal of the battery pack 200. The whole process is convenient and quick, and also avoids the problem of maintenance failure due to the excessive size of the battery pack 200.

[0123] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
