[0039] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.

[0040] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0041] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0042] Example 1

[0043] like Figure 1 As shown, the present invention provides a battery shelf 100 for supporting a battery compartment. The battery shelf 100 includes side beams 10. Specifically, the battery shelf 100 includes a front beam 20, a rear beam 30, and two side beams 10. The front beam 20, the rear beam 30, and the two side beams 10 form a rectangular frame 201 structure. The front beam 20 and the rear beam 30 are arranged opposite to each other, and the two side beams 10 are arranged opposite to each other. Preferably, the two side beams 10 have the same structure. The side beam 10 includes a body 11, wherein:

[0044] like Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, the body 11 is formed by bending sheet metal. The body 11 includes a top plate 111, a bottom plate 112, and a side plate 113. That is, the top plate 111, bottom plate 112, and side plate 113 are an integral structure. The top plate 111 is connected to the top of the side plate 113, and the bottom plate 112 is connected to the bottom of the side plate 113. The top plate 111 and bottom plate 112 are located on the same side of the side plate 113, meaning the body 11 is a hollow structure with one open side. In other words, the cross-section of the body 11 is C-shaped. This structure can improve the overall strength of the side beam 10. Figure 4 and Figure 9 As shown, the top plate 111 is stepped. Specifically, the top plate 111 includes a first stepped surface 1111, a second stepped surface 1112, and a transition connecting surface 1113 connecting the first stepped surface 1111 and the second stepped surface 1112. The first stepped surface 1111 is located above the second stepped surface 1112. The second stepped surface 1112 is configured to support the battery pack, that is, the battery pack can be placed on the second stepped surface 1112. The transition connecting surface 1113 can limit and guide the insertion operation of the battery pack, so as to prevent the battery pack from colliding with the energy storage rack 200 during the insertion process. Friction is generated between them, making it simple and convenient to insert the battery box into the energy storage rack 200, and also providing a buffer protection for the battery box to prevent external forces from directly impacting it. The first step surface 1111 ensures the overall strength of the side beam 10. The side plate 113 is configured to connect with the energy storage rack 200, that is, during use, the side plate 113 connects with the energy storage rack 200 to fix the battery shelf 100 to the energy storage rack 200. The battery box is placed on the top plate 111 of the side beam 10 to support it.

[0045] It should be noted that the number of reinforcing members 12 can be adapted to the actual weight of the battery compartment borne by the side beam 10. For example, when the weight of the battery compartment is large, multiple reinforcing members 12 can be connected in the main body 11 at intervals. When the weight of the battery compartment is small, only one reinforcing member 12 can be set in the middle of the side beam 10. This will not be elaborated further here.

[0046] The battery shelf 100 of the present invention improves the overall strength of the side beam 10 by bending the body 11 into a C-shaped cross-section using sheet metal.

[0047] Furthermore, such as Figure 4 As shown, a plastic plate is connected to the second step surface 1112, which is used to support the battery compartment. For example, the plastic plate is a polycarbonate board 13 (PC board). The polycarbonate board 13 has good wear resistance and a smooth surface, making it easier to move the battery compartment onto the battery shelf 100.

[0048] Of course, the plastic sheet can also be a polypropylene sheet (PP sheet) or a polyethylene terephthalate sheet (PET sheet), as long as it meets the requirement of reducing the friction between the battery compartment and the second step surface 1112.

[0049] Furthermore, the plastic sheet (polycarbonate sheet 13) is connected to the second step surface 1112 via a connector 14. The connector 14 can be a bolt, a fixing pin, or a rivet. In this embodiment, a bolt is preferred to facilitate the disassembly and installation of the polycarbonate sheet 13, thereby facilitating the replacement of the polycarbonate sheet 13.

[0050] Specifically, a groove is provided on the polycarbonate plate 13, and the head of the bolt is embedded in the groove to ensure that the bolt does not protrude from the polycarbonate plate 13, thereby ensuring the flatness of the surface of the polycarbonate plate 13, which facilitates the movement of the battery box to the battery shelf 100.

[0051] Furthermore, such as Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, the height of the transition connection surface 1113 is less than the height of the battery box, so that the overall size of the side beam 10 will not occupy too much space of the energy storage rack, thereby improving the utilization rate of the energy storage rack.

[0052] Furthermore, the height of the transition connection surface 1113 is less than the height of the side plate 113, so as to facilitate the assembly between the side plate 113 and the energy storage frame 200.

[0053] Preferably, the height of the transition connection surface 1113 is 2mm. This height facilitates the assembly between the side plate 113 and the energy storage frame 200, limits and guides the insertion of the battery box, and facilitates processing and manufacturing.

[0054] It should be noted that the height of the transition connection surface 1113 can be less than 2mm or greater than 2mm, such as 1.5mm, 3mm, etc., as long as the height of the transition connection surface 1113 is less than the height of the side plate 113.

[0055] In one embodiment, such as Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, the distance between the second step surface 1112 and the base plate 112 is less than or equal to three-quarters of the height of the battery box. That is, the vertical dimension of the opening of the C-shaped side beam 10 is less than or equal to three-quarters of the height of the battery box. Furthermore, the distance between the second step surface 1112 and the base plate 112 is greater than the maximum outer diameter of the connector (bolt) so that the bolt can be inserted into the interior of the side beam 10 without causing the overall size of the side beam 10 to be too large, thereby improving the space utilization of the energy storage rack.

[0056] Furthermore, the side beam 10 also includes a reinforcing member 12, which is disposed within the body 11. One end of the reinforcing member 12 is connected to the second step surface 1112, and the other end of the reinforcing member 12 is connected to the side plate 113 and / or the bottom plate 112. The reinforcing member 12 can further increase the strength of the side beam 10, thereby enabling the side beam 10 to have sufficient support strength to support the large battery box.

[0057] In one specific example of this embodiment, such as Figure 5 and Figure 6As shown, the reinforcing member 12 includes a first connecting plate 121, a second connecting plate 122, and a third connecting plate 123. The first connecting plate 121 and the second connecting plate 122 are connected to both ends of the third connecting plate 123, and the first connecting plate 121 and the second connecting plate 122 are located on both sides of the third connecting plate 123. Specifically, the third connecting plate 123 is arranged parallel to the side plate 113. The first connecting plate 121 is connected to the upper end of the third connecting plate 123, and the second connecting plate 122 is connected to the lower end of the third connecting plate 123. The first connecting plate 121 and the second connecting plate 122 are arranged parallel to each other. Preferably, the first connecting plate 121, the second connecting plate 122, and the third connecting plate 123 are arranged parallel to each other. The three connecting plates 123 are an integral structure. Specifically, the reinforcing member 12 is an integral structure formed by bending sheet metal. The first connecting plate 121 is connected to the second step surface 1112, and the second connecting plate 122 is connected to the base plate 112. Specifically, the first connecting plate 121 is welded to the second step surface 1112, and the second connecting plate 122 is welded to the base plate 112. The welding connection method is simple and reliable, which can ensure the reliability of the connection between the reinforcing member 12 and the body 11. Of course, the first connecting plate 121 can also be connected to the second step surface 1112 by rivets, and the second connecting plate 122 can also be connected to the base plate 112 by rivets.

[0058] Furthermore, such as Figure 5 and Figure 6 As shown, the third connecting plate 123 has folded edges 1231 on both sides. The folded edges 1231 are connected to the side plate 113. Specifically, the folded edges 1231 are welded to the side plate 113 to improve the reliability of the connection between the connector 14 and the body 11, thereby ensuring the overall strength of the side beam 10. Of course, the folded edges 1231 can also be glued to the side plate 113. The two folded edges 1231 can extend towards each other or backwards. Preferably, for ease of processing and manufacturing, the two folded edges 1231 extend backwards from each other.

[0059] In another specific example of this embodiment, such as Figure 10 and Figure 11 As shown, the reinforcing member 12 includes a horizontal plate 124 and two vertical plates 125. The two vertical plates 125 are respectively connected to both sides of the horizontal plate 124 and located below the horizontal plate 124. That is, the reinforcing member 12 is a frame structure with an open bottom. Specifically, the top surface of the two vertical plates 125 is in the same plane as the upper surface of the horizontal plate 124. The upper surface of the horizontal plate 124 abuts against the bottom surface of the second step surface 1112. Both vertical plates 125 are connected to the side plate 113, and the lower surface of the two vertical plates 125 abuts against the upper surface of the bottom plate 112. This allows the reinforcing member 12 to provide reinforcement support for the battery box placed on the second step surface 1112, thereby enabling the side beam 10 to stably support the large battery box.

[0060] Specifically, the two vertical plates 125 are welded to the side plate 113 to ensure the connection strength between the reinforcing member 12 and the side beam 10. Of course, the vertical plates 125 can also be connected to the side plate 113 by bolts or rivets, as long as the reinforcing member 12 is securely connected to the side beam 10.

[0061] Furthermore, such as Figure 10 and Figure 11 As shown, the end of the vertical plate 125 facing the side plate 113 is provided with a flange 1251. The flange 1251 is connected to the side plate 113. The flange 1251 can increase the connection strength between the vertical plate 125 and the side plate 113, thereby ensuring the reliability of the connection between the reinforcing member 12 and the body 11.

[0062] It should be noted that in this embodiment, the reinforcing member 12 is an integral structure formed by bending sheet metal. Such a structure can ensure the overall strength of the reinforcing member 12. Of course, the components of the reinforcing member 12 can also be an integral structure welded together, which will not be elaborated here.

[0063] Example 2

[0064] like Figure 12 As shown, the present invention also provides an energy storage rack 200, which includes at least one of the above-mentioned battery racks 100. Specifically, the energy storage rack 200 includes a frame 201, and the battery racks 100 are installed in the frame 201.

[0065] The energy storage rack 200 of the present invention has the battery shelf 100 described above, and therefore the energy storage rack 200 has the advantage of being able to stably place large battery boxes.

[0066] Furthermore, the energy storage rack 200 also includes a column 2011. Specifically, the frame 201 includes a column 2011, and the side beams 10 of the battery rack 100 are connected to the column 2011. When multiple battery boxes need to be placed, multiple battery racks 100 are connected from top to bottom on the column 2011. The internal space of the frame 201 is divided into multiple accommodating cavities by the multiple battery racks 100. Each accommodating cavity can hold a battery box, which is supported by the battery rack 100.

[0067] Example 3

[0068] like Figure 13 As shown, the present invention also provides a battery cluster, which includes the above-mentioned energy storage rack 200 and at least one battery box 300. The battery box 300 is inserted into the energy storage rack 200, and the number of battery boxes 300 can be adjusted according to actual use needs and the capacity of the energy storage rack 200.

[0069] The battery cluster of the present invention has the above-described energy storage rack, and thus has the advantage of stable placement of large battery packs.

[0070] In summary, the battery rack of the present invention improves the overall strength of the side beams by bending the body into a C-shaped cross-section using sheet metal parts. Furthermore, by setting reinforcing members within the body, the strength of the side beams is further improved, giving the side beams sufficient support strength so that they can stably support large battery boxes.

[0071] The battery rack of the present invention, by designing the top plate as stepped, ensures the overall strength of the side beams by making the first step surface of the top plate, and the battery pack can be placed on the second step surface of the top plate. The transition connection surface of the top plate can limit and guide the insertion operation of the battery pack, thereby avoiding friction between the battery pack and the energy storage rack during the insertion process, making the operation of inserting the battery pack into the energy storage rack simple and convenient, and also providing a buffer protection for the battery pack to prevent external forces from directly impacting the battery pack.

[0072] The battery shelf of the present invention, by connecting a polycarbonate plate to the second step surface, utilizes the relatively smooth surface of the polycarbonate plate to make it easier to move the battery pack onto the battery shelf;

[0073] The energy storage rack of the present invention has the above-mentioned battery rack, and therefore the energy storage rack has the advantage of being able to stably place large battery packs.

[0074] The battery cluster of the present invention has the above-described energy storage rack, and thus has the advantage of stable placement of large battery packs.
