Description

Technical Field

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

[0002] Energy storage containers, as a highly efficient energy storage device, have been widely used in various scenarios. In energy storage containers, battery packs are typically pushed into slides composed of battery brackets using loading and unloading tools, and then secured in predetermined positions by limiting structures on the battery brackets, thus providing a certain degree of vibration resistance. However, the reliability of existing battery bracket limiting structures is poor. During transportation, energy storage containers are often subjected to vibration and impact, which can easily cause battery packs to shift or fall, posing safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a battery bracket and an energy storage device, which aims to solve the problem of poor reliability of existing battery bracket limiting structures.

[0004] To solve the above-mentioned technical problems, the present invention provides a battery holder, comprising:

[0005] The bracket body extends along a first direction and includes a first bracket portion and a second bracket portion connected together. The first bracket portion and the second bracket portion are respectively used to abut against one side of the battery pack in a second direction and a third direction. A first limiting portion is provided on the first bracket portion, which is used to abut against the side of the battery pack away from the second bracket portion. The first direction, the second direction, and the third direction are perpendicular to each other.

[0006] A first limiting member is disposed on the bracket body and is used to connect one end of the battery pack in the first direction.

[0007] The second limiting member is disposed on the bracket body and is used to abut against the side of the battery pack away from the first limiting member;

[0008] Wherein, the second limiting member has a protruding insertion portion on its surface near the first limiting member, the insertion portion being used to be inserted into the slot of the battery pack; and / or, the first bracket portion has a protruding second limiting portion on its surface near the battery pack, so that the first bracket portion abuts against the battery pack through the second limiting portion.

[0009] To achieve the above objectives, this utility model also provides an energy storage device, comprising:

[0010] Battery holder, wherein the battery holder is the aforementioned battery holder;

[0011] The battery pack has two battery brackets at each end in the second direction.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The battery pack can be pushed in from the end of the two battery brackets away from the second limiting member, and slides between the two battery brackets along the second bracket portion of the bracket body until it contacts the second limiting member, so that the battery pack reaches a preset depth position. Then, the first limiting members of the two battery brackets are fixedly connected to the battery pack. At this time, the first bracket portions of the two battery brackets can limit the battery pack in a second direction, and the first and second limiting members can limit the battery pack in a first direction. The second bracket portion and the first limiting portion on the bracket body can limit the battery pack in a third direction. This battery bracket limiting structure has high reliability and simplifies the structural design and manufacturing complexity of the battery bracket. In addition, when the second limiting member is provided with a plug-in portion, the plug-in engagement between the plug-in portion and the slot of the battery pack can limit the battery pack in a third direction. When the first bracket portion is provided with a second limiting portion, the abutment engagement between the second limiting portion and the battery pack can not only limit the battery pack in a second direction, but also reduce the friction between the battery pack and the bracket body.

[0033] This utility model provides a battery bracket that can be used in energy storage devices such as energy storage containers. The following description will use the battery bracket in an energy storage container as an example. Figures 1 to 4 Various embodiments of the battery holder provided by this utility model are shown. Figures 5 to 12 Various embodiments of the energy storage device provided by this utility model are shown.

[0034] Please see Figures 1 to 6 In some embodiments, the battery holder 100 includes a holder body 1, a first limiting member 2, and a second limiting member 3. The holder body 1 extends along a first direction and includes a first holder portion 11 and a second holder portion 12 connected together. The first holder portion 11 and the second holder portion 12 are respectively used to abut against the battery pack 200 on one side in the second direction and the third direction. A first limiting portion 13 is provided on the first holder portion 11, which is used to abut against the side of the battery pack 200 away from the second holder portion 12. The first direction, the second direction, and the third direction are perpendicular to each other. The first limiting member 2 is provided on the holder body 1 and is used to connect one end of the battery pack 200 in the first direction. The second limiting member 3 is provided on the holder body 1 and is used to abut against the side of the battery pack 200 away from the first limiting member 2.

[0035] Specifically, the battery pack 200 is typically square-shaped, with one of the first, second, and third directions being the length direction of the battery pack 200, another being the width direction, and the remaining direction being the thickness direction. Optionally, please refer to... Figures 1 to 6In some embodiments, the first direction is the length direction of the battery pack 200, the second direction is the width direction of the battery pack 200, and the third direction is the thickness direction of the battery pack 200. Hereinafter, the first direction is defined as the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction.

[0036] The bracket body 1 is used to support the battery pack 200. The bracket body 1 extends along the front-to-back direction and includes a first bracket portion 11 and a second bracket portion 12 connected together. The first bracket portion 11 and the second bracket portion 12 are generally plate-shaped. The plate surface of the first bracket portion 11 is perpendicular to the left-right direction, and the plate surface of the second bracket portion 12 is perpendicular to the top-bottom direction. The lower end of the first bracket portion 11 is connected to the left or right end of the second bracket portion 12, and the first bracket portion 11 and the second bracket portion 12 are perpendicular, so that the cross-section of the bracket body 1 is L-shaped. The upper end of the first bracket portion 11 is provided with a first limiting portion 13 that is vertically spaced opposite to the second bracket portion 12. The bracket body 1 can be made of materials such as galvanized sheet, carbon steel sheet, or stainless steel sheet.

[0037] The first limiting member 2 and the second limiting member 3 are arranged at intervals on the bracket body 1. The second limiting member 3 is located on the side of the first bracket part 11 near the second bracket part 12, and the second limiting member 3 is located on the side of the second bracket part 12 near the first bracket part 11. The two battery brackets 100 arranged symmetrically on the left and right can form a slide rail. The battery pack 200 is pre-moved to a position that roughly matches the assembly position of the battery bracket 100 by a forklift or loading and unloading tool. It is gradually pushed between the two battery brackets 100 with the first limiting member 2 at one end and the second bracket part 12 of the bracket body 1. At this time, the bottom surface of the battery pack 200 contacts the two second bracket parts 12. The position of the battery pack 200 is finely adjusted according to the left and right limiting members (i.e., the first bracket parts 11 of the two battery brackets 100) to straighten the angle of the battery pack 200. When the battery pack 200 is pushed into the second limiting member 3 to a certain depth, the first limiting part 13 on the two battery brackets 100 will press down on the battery pack 200, restricting the battery pack 200 to a vertical position. During the process of pushing the battery pack 200 in, when the tail of the battery pack 200 contacts the second limiting member 3 on the two battery brackets 100, and the second limiting member 3 can restrict the battery pack 200 from being pushed in further, it means that the battery pack 200 has reached the preset depth position. At this time, the first limiting member 2 on the two battery brackets 100 and the end of the battery pack 200 are fixed, so that the first limiting member 2 and the second limiting member 3 can jointly restrict the displacement of the battery pack 200 in the depth direction (i.e., the first direction). Among them, the end of the battery pack 200 is the end of the battery pack 200 in the length direction that abuts against the first limiting member 2, and the tail of the battery pack 200 is the end of the battery pack 200 in the length direction that abuts against the second limiting member 3.

[0038] The specific shape and style of the second limiting member 3 can be set according to the actual situation. For example, the second limiting member 3 can be block-shaped, plate-shaped, or sheet-shaped. The following will take the second limiting member 3 as a limiting baffle as an example. In this case, the plate surface of the second limiting member 3 is perpendicular to the front-back direction. The second limiting member 3 can be integrally formed with the bracket body 1; the second limiting member 3 can also be fixed to the bracket body 1 by welding or bolting. Optionally, in some embodiments, the part of the second limiting member 3 that abuts against the battery pack 200 is provided with an elastic buffer layer. Foam or other elastic buffer material can be provided on the plate surface of the second limiting member 3 near the first limiting member 2, thereby forming an elastic buffer layer on the plate surface of the second limiting member 3 near the first limiting member 2. In this way, when the second limiting member 3 comes into contact with the battery pack 200, it can prevent the second limiting member 3 from damaging the surface of the battery pack 200.

[0039] Optionally, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figures 9 to 11 In some embodiments, the second limiting member 3 has a protruding insertion portion 31 on its surface near the first limiting member 2, and the insertion portion 31 is used to be inserted into the slot 210 of the battery pack 200.

[0040] Specifically, the second limiting member 3 has a protruding insertion portion 31 extending in the front-to-back direction on its surface near the first limiting member 2, and two slots 210 are provided on the end face of the tail of the battery pack 200. When the battery pack 200 is pushed into the preset depth position between the two battery brackets 100, the insertion portions 31 on the two battery brackets 100 are respectively inserted into the two slots 210 of the battery pack 200, thereby restricting the vertical displacement of the battery pack 200.

[0041] The first bracket portion 11 of the bracket body 1 is used to abut against the left or right side of the battery pack 200. The first bracket portion 11 can abut against the battery pack 200 through the plate surface of the first bracket portion 11 near the second bracket portion 12; the first bracket portion 11 can also abut against the battery pack 200 through other structural components provided on the plate surface of the first bracket portion 11 near the second bracket portion 12. Optionally, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 In some embodiments, a second limiting part 14 protrudes from the surface of the first bracket part 11 near the battery pack 200, so that the first bracket part 11 abuts against the battery pack 200 through the second limiting part 14.

[0042] Specifically, a second limiting part 14 is protruding from the plate surface of the first bracket part 11 near the second bracket part 12. When the battery pack 200 is pushed into the preset depth position between the two battery brackets 100, the second limiting parts 14 on the two battery brackets 100 respectively abut against the left and right sides of the battery pack 200, thereby restricting the displacement of the battery pack 200 in the left and right directions. By providing the second limiting part 14 on the first bracket part 11 of the bracket body 1, the contact area between the second limiting part 14 and the battery pack 200 can be reduced or direct contact between the second limiting part 14 and the battery pack 200 can be avoided, thereby reducing the friction between the battery pack 200 and the bracket body 1.

[0043] The battery tray 100 is provided with a plug-in portion 31 and / or a second limiting portion 14. It is possible to provide only the plug-in portion 31 on the battery tray 100 without providing the second limiting portion 14. For example, please refer to [link to relevant documentation]. Figure 1 In some embodiments, the battery tray 100 is a first battery tray 100a, which only has a plug-in portion 31; alternatively, only a second limiting portion 14 may be provided on the battery tray 100 without the plug-in portion 31. For example, please refer to [link to relevant documentation]. Figure 2 In some embodiments, the battery tray 100 is a second battery tray 100b, and the second battery tray 100b is only provided with the second limiting part 14; alternatively, the second limiting part 14 and the insertion part 31 may be provided on the battery tray 100 at the same time, for example, please refer to Figure 3 and Figure 4 In some embodiments, the battery holder 100 is a third battery holder 100c or a fourth battery holder 100d. The third battery holder 100c is provided with a second limiting part 14 and a plug-in part 31, and the fourth battery holder 100d is provided with a second limiting part 14 and a plug-in part 31.

[0044] In the battery holder 100 of this utility model, the battery pack 200 can be pushed in from the end of the two battery holders 100 away from the second limiting member 3, and slide along the second bracket part 12 of the holder body 1 into the space between the two battery holders 100 until it contacts the second limiting member 3, so that the battery pack 200 reaches a preset depth position. Then the first limiting member 2 of the two battery holders 100 is fixedly connected to the battery pack 200. At this time, the first bracket part 11 of the two battery holders 100 can limit the battery pack 200 in the second direction, and the first limiting member 2 and the second limiting member 3 can limit the battery pack 200 in the first direction. The second bracket part 12 and the first limiting part 13 on the holder body 1 can limit the battery pack 200 in the third direction. This limiting structure of the battery holder 100 has high reliability and simplifies the structural design and processing complexity of the battery holder 100. Furthermore, when the second limiting member 3 is provided with a plug-in part 31, the plug-in engagement between the plug-in part 31 and the slot 210 of the battery pack 200 can limit the battery pack 200 in the third direction; when the first bracket part 11 is provided with a second limiting part 14, the abutting engagement between the second limiting part 14 and the battery pack 200 can not only limit the battery pack 200 in the second direction, but also reduce the friction between the battery pack 200 and the bracket body 1.

[0045] A first limiting part 13 is provided at the upper end of the first bracket part 11. One first limiting part 13 can be provided between the first limiting member 2 and the second limiting member 3, or multiple first limiting parts 13 can be provided at intervals. The specific shape and style of the first limiting part 13 can be set according to the actual situation; for example, the first limiting part 13 can be a boss or a folded edge, etc. Optionally, please refer to... Figures 1 to 4 In some embodiments, the first limiting part 13 is a folded edge, which is formed by bending the first limiting part 13 at the upper end of the first bracket part 11 with a bending knife. This processing method of the first limiting part 13 is relatively simple.

[0046] Further, please refer to Figures 1 to 4 In some embodiments, the end of the first limiting portion 13 near the first limiting member 2 is inclined upwards, and the inclined portion of the first limiting portion 13 forms an inclined guide section 131. In the direction from the first limiting member 2 to the second limiting member 3, the distance between the inclined guide section 131 and the second bracket portion 12 gradually decreases, so that the inclined guide section 131 can guide the battery pack 200, which is beneficial for the battery pack 200 to enter between the first limiting portion 13 and the second bracket portion 12.

[0047] The second limiting member 3 may be provided with a plug-in portion 31. The specific shape and style of the plug-in portion 31 can be set according to the actual situation. For example, the plug-in portion 31 may be provided in the shape of a block, plate, or sheet. Optionally, please refer to Figure 1 In some embodiments, the insertion portion 31 is provided in a plate-like form. Optionally, please refer to... Figure 3 and Figure 4 In some embodiments, the cross-section of the plug portion 31 is L-shaped.

[0048] Optionally, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 9 and Figure 11 In some embodiments, in the direction from the first limiting member 2 to the second limiting member 3, the end of the insertion portion 31 near the first limiting member 2 is inclined toward the direction near the second bracket portion 12.

[0049] Specifically, the end of the plug portion 31 near the first limiting member 2 is inclined upwards, so that when the plug portion 31 on the battery bracket 100 is inserted into the slot 21 of the battery pack 200, the end of the plug portion 31 near the first limiting member 2 can more easily enter the slot 21 of the battery pack 200.

[0050] Optionally, please refer to Figure 9 In some embodiments, the slot 210 has an inclined groove sidewall 220 that abuts against the insertion portion 31 and is inclined, and the shape of the end of the insertion portion 31 near the first limiting member 2 is adapted to the shape of the inclined groove sidewall 220.

[0051] Specifically, the insertion part 31 is a wedge-shaped inclined limiting piece. The wedge-shaped inclined limiting piece is bent at a certain angle by a bending knife. The wedge-shaped structure of the wedge-shaped inclined limiting piece cooperates with the inclined groove side wall 220 of the slot 210, which can not only limit the vertical displacement of the battery pack 200, but also guide the insertion part 31 into the slot 21.

[0052] A second limiting part 14 may be provided on the first bracket part 11. One second limiting part 14 or multiple second limiting parts 14 arranged front to back may be provided between the first limiting member 2 and the second limiting member 3. The specific arrangement of the second limiting part 14 can be set according to the actual situation. Optionally, please refer to [reference needed]. Figure 2 and Figure 3 In some embodiments, the second limiting portion 14 is a convex hull 14a, and multiple convex hulls 14a are provided at intervals along the first direction.

[0053] Specifically, the second limiting part 14 is a protrusion 14a, and multiple protrusions 14a are provided at intervals between the first limiting member 2 and the second limiting member 3. The protrusions 14a are arranged on the side of the first bracket part 11 near the second bracket part 12, and the protrusions 14a can realize the left and right limiting of the battery pack 200.

[0054] The second limiting part 14 is typically a buffer limiting part, meaning that the second limiting part 14 has a certain buffering and limiting function. Optionally, please refer to... Figure 2 and Figure 3 In some embodiments, a portion of the first bracket portion 11 is recessed toward the battery pack 200, and the recessed portion of the first bracket portion 11 forms a protrusion 14a. The protrusion 14a can be formed by die stamping, so that the protrusion 14a has a certain left and right buffering and limiting function.

[0055] Further, please refer to Figure 2 and Figure 3 In some embodiments, a break 15 is provided between the upper and lower ends of the convex 14a and the first bracket portion 11. The convex 14a is generally arranged to extend in the front-back direction. The break 15 extending in the front-back direction between the upper and lower ends of the convex 14a and the first bracket portion 11 allows the upper and lower ends of the convex 14a to be disconnected from the first bracket portion 11, thereby further enhancing the left-right buffering and limiting function of the convex 14a.

[0056] Optionally, please refer to Figure 2 and Figure 3 In some embodiments, at least one end of the convex 14a in the first direction is provided with a guide slope 141. The guide slope 141 is provided at least at one end of the convex 14a near the first limiting member 2. Thus, during the process of the battery pack 200 contacting the convex 14a, the guide slope 141 can guide the pushing of the battery pack 200.

[0057] Optionally, please refer to Figure 4 In some embodiments, the second limiting part 14 is an anti-wear strip 14b, which extends along the first direction.

[0058] Specifically, the first bracket part 11 is provided with one or more anti-wear strips 14b. The anti-wear strips 14b are usually made of materials such as nylon. The anti-wear strips 14b can limit the left and right movement of the battery pack 200 and also reduce the friction between the battery pack 200 and the bracket body 1.

[0059] The battery holder 100 can be used for mounting either the short battery pack 200 or the long battery pack 200. Optionally, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, two first limiting members 2 are respectively disposed at both ends of the bracket body 1 in a first direction, and a second limiting member 3 is disposed between the two first limiting members 2.

[0060] Specifically, the front and rear ends of the bracket body 1 are respectively provided with two first limiting members 2, and the middle part of the bracket body 1 can be provided with one or two second limiting members 3, so that the two battery brackets 100 can be used to carry two short battery packs 200.

[0061] When two first limiting members 2 are respectively disposed at both ends of the bracket body 1 in a first direction, and a second limiting member 3 is disposed between the two first limiting members 2, the second limiting member 3 may or may not have a plug-in portion 31. Optionally, please refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, when two first limiting members 2 are respectively disposed at both ends of the bracket body 1 in the first direction, and a second limiting member 3 is disposed between the two first limiting members 2, the second limiting member 3 is provided with two insertion portions 31 on two opposite surfaces in the first direction.

[0062] Specifically, the battery tray 100 is arranged symmetrically front and back. The battery tray 100 is provided with a second limiting member 3 and two first limiting members 2. The front and rear surfaces of the second limiting member 3 are respectively provided with two insertion parts 31. Thus, when two short battery packs 200 are installed on the battery tray 100, the two insertion parts 31 on the second limiting member 3 respectively form an insertion engagement with the slots 210 of the two short battery packs 200.

[0063] Optionally, please refer to Figure 3 , Figure 4 and Figure 10 In some embodiments, the first limiting member 2 and the second limiting member 3 are respectively disposed at both ends of the bracket body 1 in the first direction.

[0064] Specifically, the front and rear ends of the bracket body 1 are respectively provided with a first limiting member 2 and a second limiting member 3, so that the two battery brackets 100 can be used to support a long battery pack 200.

[0065] When the first limiting member 2 and the second limiting member 3 are respectively disposed at both ends of the bracket body 1 in the first direction, the second limiting member 3 may or may not have a plug-in portion 31. Optionally, please refer to Figure 3 , Figure 4 , Figure 10 and Figure 11 In some embodiments, when the first limiting member 2 and the second limiting member 3 are respectively disposed at both ends of the bracket body 1 in the first direction, the second limiting member 3 is provided with a plug-in portion 31.

[0066] The first limiting member 2 connects the end of the battery pack 200 to the bracket body 1. The first limiting member 2 and the battery pack 200 can be fixedly connected by bolts or other means. Please refer to [link / reference]. Figure 1 , Figure 5 , Figure 6 and Figure 8 The first limiting member 2 can be used to abut against the side of the battery pack 200 away from the second limiting member 3, that is, the first limiting member 2 can be used to abut against the front or rear face of the battery pack 200; please refer to Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 12 The first limiting member 2 can be used to abut against the side of the battery pack 200 away from the first limiting part 13, that is, the first limiting member 2 can be used to abut against the bottom surface of the battery pack 200.

[0067] Optionally, please refer to Figures 1 to 4 In some embodiments, a support member 4 is provided on the bracket body 1. The support member 4 is usually located on the lower side of the bracket body 1, and the support member 4 can enhance the structural strength of the battery bracket 100.

[0068] This utility model also provides an energy storage device, which can be an energy storage container, etc. Figures 5 to 12 Various embodiments of the energy storage device provided by this utility model are shown.

[0069] Please see Figures 5 to 12 In some embodiments, the energy storage device 1000 includes a battery bracket 100 and a battery pack 200, with two battery brackets 100 respectively provided at both ends of the battery pack 200 in the second direction.

[0070] Specifically, the energy storage device 1000 includes two supports 300 spaced apart horizontally, with multiple battery packs 200 arranged vertically between the two supports 300.
