Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery bracket and a battery compartment. Background Art

[0002] A battery compartment is an energy storage device that includes multiple battery packs. Currently, the requirements for the volume energy density and mass energy density of energy storage battery compartments are becoming increasingly higher, and large battery pack solutions are gradually becoming the mainstream in the market.

[0003] In related art, the battery compartment includes a bracket assembly, which includes two L-shaped brackets. The two L-shaped brackets are symmetrically arranged on two opposite inner walls of the battery compartment to support the battery pack. The bracket assembly is arranged in layers along the height direction of the battery compartment to achieve stacking of the battery packs in the height direction. When installing the battery pack, the battery pack lifting fixture is positioned to the L-shaped bracket position, first positioning it in the width direction, then the battery pack to be installed and fixed is transferred to the lifting fixture, and then positioning it in the height direction. Finally, the battery pack is pushed horizontally into the battery compartment to complete the installation.

[0004] However, when the battery pack is positioned in height, the gap between the bracket components on different layers is small, and the positioning speed is slow. In addition, the end of the L-shaped bracket facing the lifting tool is an exposed steel structure, which is more likely to collide with the bottom of the battery pack, causing damage to the battery pack such as insulation damage, structural deformation, and cold plate cracking.

[0005] Accordingly, this field requires a new technical solution to solve the above problems. Utility Model Content

[0006] In order to solve at least one of the above-mentioned problems in the prior art, that is, to solve the problem in the related art that when the battery pack is positioned in the height direction, the gap between the different layers of bracket assemblies is small, and the positioning speed is slow; the L-shaped bracket is more likely to collide with the bottom of the battery pack, resulting in insulation damage, structural deformation, cold plate cracking and other damages to the battery pack.

[0007] In the first aspect, the present application provides a battery bracket for use in a battery compartment, the battery bracket comprising: a fixing plate for being fixedly connected to the inner wall surface of the battery compartment; a support plate vertically connected to the fixing plate to form an L-shaped structure, the support plate being used to support a battery pack; a guide plate arranged at the front end of the support plate, the guide plate being inclined downward and in a direction away from the support plate.

[0008] In some embodiments, the angle between the guide plate and the first direction is a first angle, and the value range of the first angle is 40° to 50°; wherein, the support plate also includes a rear end, and the first direction extends from the rear end to the front end.

[0009] In some embodiments, the length of the guide plate ranges from 12 cm to 16 cm.

[0010] In some embodiments, the thickness of the fixing plate is greater than or equal to 3 mm; and / or the thickness of the supporting plate is greater than or equal to 3 mm; and / or the thickness of the guide plate is greater than or equal to 3 mm.

[0011] In some embodiments, the support plate is further provided with one or more battery pack fixing holes.

[0012] In some embodiments, the support plate includes a bottom surface and a top surface that are relatively arranged, and the fixing plate is arranged on the top surface; wherein, the battery holder also includes a wedge-shaped support structure, and the wedge-shaped support structure is arranged on the bottom surface and is located on the side of the bottom surface close to the fixing plate.

[0013] In some embodiments, the guide plate and the support plate are connected by welding.

[0014] In the second aspect, the present application provides a battery compartment, which includes: a cabinet body, including a first inner wall and a second inner wall arranged opposite to each other; a battery bracket group, including two of the above-mentioned battery brackets, one of the two battery brackets is arranged on the first inner wall, and the other of the two battery brackets is symmetrically arranged on the second inner wall.

[0015] In some embodiments, the cabinet body further includes a cabinet opening, and the guide plate in the battery bracket is arranged close to the cabinet opening.

[0016] In some embodiments, the battery compartment includes a plurality of battery bracket groups, and the battery bracket groups are evenly arranged along the height direction of the battery compartment.

[0017] Based on the above technical solution, the battery holder in this application includes a fixing plate and a support plate. The fixing plate is fixedly connected to the inner wall of the battery compartment, fixing the battery holder to the inner wall of the battery compartment. When the battery pack is installed in the battery compartment, the battery pack is located on the upper surface of the support plate, so that the support plate supports the battery pack. In addition, a downwardly inclined guide plate is provided at the front end of the support plate. The guide plate can play a guiding role. When the battery pack is positioned in the height direction, as long as the bottom of the battery pack contacts the guide plate, the battery pack can be smoothly pushed into the battery compartment, which is conducive to improving the speed of the height positioning of the battery pack. In addition, because the guide plate is inclined, the bottom surface of the battery pack contacts the inclined surface of the guide plate, rather than contacting the end of the L-shaped bracket as in the related art. The inclined surface has a larger area and is easier to position, which greatly reduces the risk of collision between the battery pack and the battery holder, thereby reducing the risk of damage to the battery pack such as insulation damage, structural deformation, and cold plate cracking.

[0028] A battery compartment is an energy storage device that includes multiple battery packs. Currently, the requirements for the volume energy density and mass energy density of energy storage battery compartments are becoming increasingly higher, and large battery pack solutions are gradually becoming the mainstream in the market.

[0029] Combine Figure 1 As shown, in the related art, the battery compartment includes a bracket assembly, and the bracket assembly includes two L-shaped brackets 10. The two L-shaped brackets 10 are symmetrically arranged on the two opposite inner wall surfaces of the battery compartment to jointly support the battery pack. The bracket assembly is arranged in layers along the height direction of the battery compartment to achieve stacking of the battery pack in the height direction. When installing the battery pack, the lifting fixture of the battery pack is positioned to the position of the L-shaped bracket 10, first positioning in the width direction, and then the battery pack to be installed and fixed is transferred to the lifting fixture, and then positioning in the height direction is performed. Finally, the battery pack is pushed horizontally into the battery compartment to complete the installation.

[0030] However, when the battery pack is positioned in the height direction, the gap between the bracket components on different layers is small, and the positioning speed is slow; in addition, the end of the L-shaped bracket 10 facing the lifting tool is an exposed steel structure, which is more likely to collide with the bottom of the battery pack, causing damage to the battery pack such as insulation damage, structural deformation, and cold plate cracking.

[0031] The present application provides a battery bracket and a battery compartment, which are conducive to improving the speed of positioning the battery pack in the height direction and reducing the risk of collision between the battery pack and the battery bracket.

[0032] In a first aspect, the present application provides a battery holder.

[0033] The battery bracket provided in this application is applied to the battery compartment, combined with Figure 2 As shown, the battery holder provided in this application includes a fixing plate 100 , a support plate 200 and a guide plate 300 .

[0034] The fixing plate 100 is used to securely connect to the inner wall of the battery compartment. Using bolts, welding, or other fastening methods, the fixing plate 100 can be securely attached to the inner wall of the battery compartment, providing stable support for the battery holder.

[0035] The support plate 200 is connected to the fixed plate 100 in an L-shaped structure, which supports the battery pack. This L-shaped structure allows the support plate 200 to extend outward to support the battery pack. The support plate 200 needs to have a certain strength and rigidity to ensure that it does not deform or break when bearing the weight of the battery pack.

[0036] A guide plate 300 is provided at the front end of the support plate 200. The guide plate 300 is tilted downward and away from the support plate 200. The guide plate 300 primarily guides and positions the battery pack during installation, ensuring smooth and accurate installation onto the support plate 200. It also reduces direct impact between the battery pack and the support plate 200, protecting the battery pack from damage.

[0037] Based on the above technical solution, the battery holder in this application includes a fixing plate 100 and a support plate 200. The fixing plate 100 is fixedly connected to the inner wall of the battery compartment, securing the battery holder to the inner wall of the battery compartment. When the battery pack is installed in the battery compartment, the battery pack is positioned on the upper surface of the support plate 200, thereby supporting the battery pack. Furthermore, a downwardly inclined guide plate 300 is provided at the front end 201 of the support plate 200. The guide plate 300 serves as a guide. When the battery pack is positioned in the vertical direction, as long as the bottom of the battery pack contacts the guide plate 300, the battery pack can be smoothly pushed into the battery compartment, which helps to speed up the vertical positioning of the battery pack. Furthermore, because the guide plate 300 is tilted, the bottom surface of the battery pack contacts the inclined surface of the guide plate 300, rather than the end of the L-shaped bracket as in the related art. This larger inclined surface makes positioning easier, significantly reducing the risk of collision between the battery pack and the battery holder, thereby reducing the risk of damage to the battery pack, such as insulation damage, structural deformation, and cold plate cracking.

[0038] Optionally, the fixing plate 100 and the support plate 200 are integrally formed, or the fixing plate 100 and the support plate 200 are fixedly connected by welding. Integral molding is typically achieved by casting, injection molding, or other molding processes, directly combining the fixing plate 100 and the support plate 200 into a single unit during the production process. This offers advantages such as high structural strength and simple assembly. Connecting the fixing plate 100 and the support plate 200 by welding offers advantages such as high flexibility, low cost, and ease of maintenance.

[0039] Optionally, the support plate 200 and guide plate 300 are integrally formed, or they are fixedly connected by welding.

This offers advantages such as high structural strength and simplified assembly. Connecting the support plate 200 and guide plate 300 by welding offers advantages such as high flexibility, low cost, and ease of maintenance.

[0040] In some embodiments, combined Figure 3 As shown, the angle between the guide plate 300 and the first direction is the first angle θ, and the value of the first angle θ ranges from 40° to 50°. The support plate 200 also includes a rear end 202, and the first direction extends from the rear end 202 to the front end 201. By limiting the first angle θ to the above range, the battery pack can be smoothly pushed into the battery compartment along the guide plate 300.

[0041] For example, the first angle θ is 40°, 41°, 43°, 45°, 46°, 47°, 48° or 50°.

[0042] In some embodiments, combined Figure 3 As shown, the length of the guide plate 300 ranges from 12 cm to 16 cm. By limiting the length of the guide plate 300 to the above range, the height positioning of the battery pack is facilitated while avoiding interference with the battery pack.

[0043] For example, the length of the guide plate 300 is 12 cm, 13 cm, 14 cm, 15 cm or 16 cm.

[0044] In some embodiments, the thickness of the fixing plate 100 is greater than or equal to 3 mm. By limiting the thickness of the fixing plate 100 to the above range, the supporting strength of the fixing plate 100 can be ensured.

[0045] For example, the thickness of the fixing plate 100 is 3 mm, 4 mm, or 5 mm.

[0046] In some embodiments, the thickness of the support plate 200 is greater than or equal to 3 mm. By limiting the thickness of the support plate 200 to the above range, the support strength of the support plate 200 can be ensured.

[0047] For example, the thickness of the support plate 200 is 3 mm, 4 mm, or 5 mm.

[0048] In some embodiments, the thickness of the guide plate 300 is greater than or equal to 3 mm. By limiting the thickness of the guide plate 300 to the above range, the support strength of the guide plate 300 can be ensured.

[0049] For example, the thickness of the guide plate 300 is 3 mm, 4 mm, or 5 mm.

[0050] In some embodiments, the fixing plate 100, the support plate 200, and the guide plate 300 have the same thickness. This arrangement is beneficial to maintaining the appearance consistency and structural stability of the battery holder.

[0051] In some embodiments, the support plate 200 is further provided with one or more battery pack fixing holes (not shown). It is understood that corresponding connection holes are reserved at the bottom of the battery pack, and bolts are sequentially passed through the fixing holes and the connection holes to fix the battery pack to the support plate 200.

[0052] In some embodiments, combined Figure 4 As shown, the support plate 200 includes a bottom surface 203 and a top surface 204 that are relatively arranged, and the fixing plate 100 is arranged on the top surface 204. Among them, the battery holder also includes a wedge-shaped support structure 205, and the wedge-shaped support structure 205 is arranged on the bottom surface, and the wedge-shaped support structure 205 is located on the side of the bottom surface close to the fixing plate 100. The wedge-shaped support structure 205 can play a role in fixing and supporting the battery holder. Due to its unique shape, the wedge-shaped structure can produce better stability when subjected to pressure. By arranging the wedge-shaped support structure 205 on the bottom surface 203 of the support plate 200 and using the wedge-shaped support structure 205 to support the battery holder, the strength and stability of the battery holder can be enhanced to prevent shaking or falling off under the weight of the battery pack.

[0053] Combine Figure 4 As shown, the wedge-shaped support structure 205 includes a first right-angled side and a second right-angled side. When the battery bracket is installed, the first right-angled side is connected to the bottom surface 203 of the support plate 200, and the second right-angled side is connected to the inner wall surface of the battery compartment.

[0054] In a second aspect, the present application provides a battery compartment.

[0055] Combine Figure 4 As shown, the battery compartment cabinet (not shown in the figure) and battery bracket group provided by this application.

[0056] The cabinet includes a first inner wall 403 and a second inner wall 404 that are oppositely arranged.

[0057] The battery holder assembly includes the two aforementioned battery holders, one of which is disposed on the first inner sidewall 403 , and the other of which is symmetrically disposed on the second inner sidewall 404 .

[0058] The two battery brackets are symmetrically arranged to support the battery pack.

[0059] Under the premise of adopting the above technical solution, the battery pack can be supported by the cooperation of two battery brackets. In addition, the battery bracket is provided with the aforementioned downwardly inclined guide plate 300. The guide plate 300 can serve as a guide. When the battery pack is positioned in the height direction, as long as the bottom of the battery pack contacts the guide plate 300, the battery pack can be smoothly pushed into the battery compartment, which helps to increase the speed of the battery pack's height positioning. In addition, because the guide plate 300 is set at an angle, the bottom surface of the battery pack contacts the inclined surface of the guide plate 300, rather than contacting the end of the L-shaped bracket as in the related art. The inclined surface has a larger area and is easier to position, greatly reducing the risk of collision between the battery pack and the battery bracket, thereby reducing the risk of damage to the battery pack such as insulation damage, structural deformation, and cold plate cracking.

[0060] In some embodiments, the cabinet body further includes a cabinet opening (not shown) and a guide plate in the battery bracket is arranged near the cabinet opening, so as to facilitate the insertion of the battery pack into the battery compartment.

[0061] In some embodiments, the battery compartment includes multiple battery bracket groups that are evenly arranged along the height direction of the battery compartment. In this way, the battery compartment is configured as a multi-layer structure in the height direction, so that the battery packs can be arranged in the battery compartment along the height direction.

[0062] Thus far, the technical solutions of the present application have been described in conjunction with the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
