Description

Technical Field

[0001] This utility model belongs to the field of battery mounting brackets, and in particular relates to a battery bracket and a battery guide. Background Technology

[0002] The battery box in the energy storage system is installed on a special bracket. The bracket generally includes a column, a tray, and a battery guide on the tray to guide and limit the battery box during the process of pushing it in. In traditional brackets, the tray and column are fixed by welding, and the battery guide is also fixed to the tray by welding. After the bracket is welded as a whole, an anti-corrosion coating is sprayed on.

[0003] To improve the structural performance of the support structure, the material needs to be changed from carbon steel to an alloy material with an anti-corrosion coating. The new material is not only stronger but also more corrosion-resistant, eliminating the need for the original painting process. However, if the internal components of the support structure are still connected by welding, the coating on the alloy material will be damaged during the welding process, which will affect the service life of the support structure.

[0004] The aforementioned problem of welding easily damaging the plating can be solved by changing the connection method between the internal components of the bracket. A Chinese utility model patent with authorization announcement number CN219959279U discloses a cabinet bracket in which the tray (i.e., the bracket beam) is connected to the uprights by bolts. However, due to space limitations, the battery guide on the tray is still welded to the tray. In this utility model patent, the battery guide is made of a long strip of sheet material. The two ends and the middle of the battery guide are bent to form a ramp. The two ends of the battery guide are attached and fixed to the side walls of the tray. During the process of pushing in the battery box, the two side walls of the battery box first contact the corresponding ramp. Guided by the ramp, the battery box gradually centers itself during the pushing process, finally reaching the center of the battery guide. If the two ends of the battery guide are also fixed to the tray by bolts, the bolts will inevitably obstruct the normal pushing in of the battery box. Therefore, how to connect the battery guide to the tray by bolts or other fasteners is a problem that must be solved when upgrading the bracket material. Utility Model Content

[0028] The present invention will be further described in detail below with reference to the embodiments.

[0029] To address the problems in the prior art, the basic concept of this utility model is to change the connection between the battery guide and the tray from welding to fastener connection, and to place the connection part for installing the fastener above and below the connection end, while ensuring that the fastener does not protrude from the limiting section, so as to avoid interference between the battery box and the fastener during the pushing process.

[0030] Specific embodiment 1 of the battery holder provided by this utility model:

[0031] A battery holder, see attached Figure 1 It includes a tray 1 and a battery guide 2, with the battery guide 2 mounted on the tray 1.

[0032] See appendix Figure 2 The tray 1 includes an integrally formed, mutually perpendicular upright plate 11 and a horizontal plate 12. During use, the horizontal plate 12 supports the battery box, while the upright plate 11 limits the movement of the battery box on its left and right sides. In this embodiment, the battery bracket is part of a support frame used to install the battery box in an energy storage system. The support frame also includes a column, and the battery bracket is fixedly connected to the column by bolts. The upright plate 11 of the tray 1 has four mating holes 17 spaced along its length, and one-way bolts 3 are installed in each of the mating holes 17. The tray 1 is installed onto the column by the one-way bolts 3.

[0033] In use, battery trays are arranged in pairs, and the battery box is installed between the two battery trays of the same pair. During the installation of the battery box, the left and right edges of the bottom of the battery box are first placed on the horizontal plates 12 of the two battery trays of the same pair, and then the battery box is pushed forward horizontally to enter the bracket. The end of the tray 1 along its length is provided with a connecting lug 13, which is used to fix the battery box to the corresponding connecting structure on the battery box by bolts after the battery box is pushed into the bracket. Moreover, after the battery box is pushed into the bracket, it is necessary to connect other pipelines, which requires the battery box to be centered in the left and right direction. A floating nut 3 is installed on the connecting lug 13 for cooperating with the bolt. The floating nut 3 can be snapped onto the connecting lug 13 without welding fixation.

[0034] The battery guide 2 is used to guide and limit the battery box during the process of pushing it in, so that the battery box is centered in the left-right direction. In this embodiment, two battery guides 2 are arranged at intervals along the length of a tray 1, which are used to guide and limit the two battery boxes respectively.

[0035] See appendix Figure 3 and attached Figure 4 The battery guide 2 specifically includes an integrally formed guide portion 21, a connecting portion 22, and a bending transition portion 23. The guide portion 21 includes a limiting section 211 and ramp sections 212 disposed at both ends of the limiting section 211 along its length. The limiting section 211 is parallel to the upright plate 11 and has a gap between it and the upright plate 11. The ramp sections 212 are used to guide the battery box from the upright plate 11 to the limiting section 211. During the process of the battery box being pushed in, it gradually centers under the action of the battery guides 2 on both sides. In this embodiment, two battery boxes can be installed on the same pair of battery brackets from the front and rear ends. Therefore, the ramp sections 212 are provided at both ends of the limiting section 211 along its length, so that the battery guide 2 can be used in both directions. Of course, in other embodiments, if only one battery box is installed on a pair of battery brackets, the ramp section 212 can be provided only at one end of the limiting section 211 along its length.

[0036] The connecting part 22 is located above the limiting section 211. The connecting part 22 is attached to the side wall of the upright plate 11 and connected to the upright plate 11 by fasteners, specifically bolts. The connecting part 22 is provided with connecting holes 24 for the fasteners to pass through, and the corresponding position of the upright plate 11 is also provided with openings 16 for the fasteners to pass through. The use of bolts as fasteners facilitates installation and also facilitates the disassembly and replacement of the battery guide 2. In other embodiments, the fasteners can also be rivets or other structures.

[0037] Three fasteners are spaced apart along the length of the connecting part 22. After the fasteners are installed, the height of the fasteners protruding from the upright plate 11 is less than the distance between the limiting section 211 and the upright plate 11. Moreover, the fasteners are all located between two vertical surfaces that pass through both ends of the limiting section 211 in the length direction and are perpendicular to the limiting section 211. That is, the fasteners do not exceed the limiting section 211 in the front-back direction, thereby avoiding collision and interference between the battery box and the fasteners during the process of being pushed in.

[0038] The lower side of the limiting segment 211 is provided with a downwardly protruding protrusion 25. Three protrusions 25 are spaced apart along the length of the limiting segment 211. The horizontal plate 12 of the tray 1 is provided with insertion holes 14 that correspond one-to-one with the protrusions 25 and are inserted into each other. During the installation of the battery guide 2, the protrusions 25 are first inserted into the corresponding insertion holes 14, and the lower side of the limiting segment 211 is made to fit against the upper surface of the horizontal plate 12 of the tray 1. Then, the connecting part 22 is fixed to the vertical plate 11 of the tray 1. The cooperation between the protrusions 25 and the insertion holes 14 facilitates the installation and positioning of the battery guide 2 and also provides support for the limiting segment 211 in the direction perpendicular to the vertical plate 11, preventing the limiting segment 211 from deforming due to unbalanced forces. Therefore, the cooperation between the protrusions 25 and the insertion holes 14 also constitutes a support structure between the limiting segment 211 and the tray 1.

[0039] The support structure in this embodiment is simple in form and easy to manufacture. Furthermore, it allows the lower edge of the limiting segment 211 to directly contact the horizontal plate 12 of the tray 1, maximizing the use of space on the tray 1 and ensuring the guiding effect of the battery guide 2 on the battery box. In other embodiments, if the strength of the battery guide 2 itself meets the usage requirements, a support structure may not be necessary.

[0040] The battery guide 2 is integrally processed from a long strip of sheet material through cutting and stamping. During processing, rectangular notches 26 are first machined at both ends of the sheet material along its length. Then, the portion of the sheet material between the two notches 26 is bent to form a bending transition portion 23. After bending, the two sides of the bending transition portion 23 are the guide portion 21 and the connecting portion 22, respectively. Then, the two ends of the guide portion 21, which are the parts corresponding to the notches 26, are bent inward to form a ramp section 212. The connecting hole 24 on the connecting portion 22 and the protruding structure 25 on the limiting section 211 are processed before bending.

[0041] In other embodiments, the length of the connecting portion 22 in the battery guide 2 can be less than the length of the limiting segment 211, so that the battery guide 2 can be bent and formed without processing the notch 26.

[0042] The battery holder in this embodiment also includes a support member 4, see Appendix. Figure 5The support member 4 provides support between the column and the horizontal plate 12 of the tray 1 to enhance the structural strength of the battery bracket. The support member 4 includes a mounting part 41 and a support part 42. The mounting part 41 has a mounting hole 43 for fixing the support member 4 to the column with bolts. The upper end of the support part 42 is provided with a positioning protrusion 44, and the corresponding position of the horizontal plate 12 is provided with a positioning hole 15 for the positioning protrusion 44 to be inserted.

[0043] The support member 4 is also made by stamping sheet metal. During processing, the outer contour of the support member 4 and the mounting hole 43 are first processed out. Then, the two sides of the sheet metal are bent to form the mounting part 41 in the middle and the support part 42 on both sides of the mounting part 41. The support part 42 is perpendicular to the mounting part 41 and the support part 42 is also perpendicular to the horizontal plate 12.

[0044] During the assembly of the bracket, the support component 4 is first fixedly installed on the column, and then the tray 1 is installed. The positioning holes 15 on the horizontal plate 12 of the tray 1 are first fitted onto the positioning protrusions 44, and then the tray 1 is fixed to the column. In this way, the support component 4, which is installed first, can position the tray 1 and improve the stability of the tray 1. During use, the support component 4 can also provide additional support for the tray 1, improving the structural strength of the battery bracket. Moreover, there is no welding between the support component 4 and the tray 1, which can effectively simplify the assembly steps and avoid damage to the plating.

[0045] Specific embodiment 2 of the battery holder provided by this utility model:

[0046] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the connecting part is located below the limiting section, and the limiting section is far away from the horizontal plate of the tray. Therefore, the support structure in this embodiment is also different from that in Embodiment 1.

[0047] Specifically, in this embodiment, the support structure is a support plate integrally formed on the vertical plate by stamping. The support plate is perpendicular to both the vertical plate and the horizontal plate. The support plate abuts against the side of the limiting section facing the vertical plate and provides support for the limiting section.

[0048] Specific embodiment 3 of the battery holder provided by this utility model:

[0049] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that there are two connecting parts. The two connecting parts are located above and below the limiting segment, respectively. A bending transition part is also provided between the two connecting parts and the limiting segment. Since the upper and lower sides of the limiting segment are supported by the bending transition part, there is no need to set up a separate support structure.

[0050] Specific embodiment 4 of the battery holder provided by this utility model:

[0051] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the support structure in this embodiment is a support part connected to the lower side of the limiting section. The support part is bent to be perpendicular to the limiting section, and the side of the support part away from the limiting section abuts against the upright plate.

[0052] Specific embodiment 5 of the battery holder provided by this utility model:

[0053] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the support structure in this embodiment is a support body set on the horizontal plate. The support body on the horizontal plate is formed by stamping. The support body is located on the side of the limiting part facing the vertical plate and abuts against the side of the limiting part facing the vertical plate, thereby providing support for the limiting part.

[0054] Specific embodiment 6 of the battery holder provided by this utility model:

[0055] This embodiment is based on embodiment 1. The difference between this embodiment and embodiment 1 is that the support member does not have a positioning protrusion. The horizontal plate of the pallet rests directly on the upper surface of the support member, and the support member can also provide support for the pallet.
