[0041] Figure 1 It is a schematic diagram of a structural explosion of a battery assembly provided by an embodiment of the utility model; Figure 2 It is a structural schematic diagram of a battery assembly provided by an embodiment of the utility model.

[0042] See also Figure 1 and Figure 2 The embodiment of the utility model first provides a mounting assembly, which is used to mount a battery box 200. The battery box 200 and the mounting assembly together constitute a battery assembly. The mounting assembly includes a mounting bracket 100 and a cover plate 300.

[0043] The mounting bracket 100 is the main body of the entire mounting assembly, and is mainly used to carry at least one battery box 200 and to connect to the vehicle body. The mounting bracket 100 includes a first frame 110 and a second frame 120 connected to each other, and the first frame 110 and the second frame 120 are arranged perpendicular to each other. The first frame 110 and the second frame 120 limit a receiving space 130, and at least one battery box 200 can be located in the receiving space 130.

[0044] It is equivalent to that the cross-section of the mounting bracket 100 is in an "L" shape, and the first frame 110, the second frame 120, and the connecting line between the first frame 110 and the second frame 120 enclose a virtual rectangular structure or a square structure, and the virtual structure of the accommodating space 130 is mainly determined according to the shape of at least one group of battery boxes 200. The accommodating space 130 is equivalent to a physical structure with a limit and a stopper on one half, and an open form on the other half. This arrangement facilitates the lifting of the battery box 200 into place and avoids interference between the battery box 200 and the mounting bracket 100 during installation.

[0045] The cover plate 300 is disposed on the top surface of the battery box 200, and the cover plate 300 is detachably connected to at least one of the first frame 110 and the second frame 120 through the connecting component 400, so as to limit the battery box 200 to the accommodating space 130. That is, the cover plate 300 can be detachably connected to the first frame 110 through the connecting component 400, or the cover plate 300 can be detachably connected to the second frame 120 through the connecting component 400, or the cover plate 300 can also be detachably connected to the first frame 110 through the connecting component 400, and at the same time be detachably connected to the second frame 120 through the connecting component 400.

[0046] The cover plate 300 is provided with a first fixing hole 310 for the connection member 400 to pass through, and the position and number of the first fixing hole 310 are set according to actual use requirements. A reinforcing plate or reinforcing rib may be provided on the cover plate 300, and the first fixing hole 310 is preferably provided at the position where the reinforcing plate or reinforcing rib is located.

[0047] During the assembly process, the battery box 200 is first stacked on the first frame 110 and the second frame 120, and then the cover 300 is covered on the topmost battery box 200. Finally, the cover 300 is connected to at least one of the first frame 110 and the second frame 120 through the connecting component 400 to form an integral battery assembly, and then the battery assembly is connected to the chassis of the vehicle body. This arrangement can simplify the installation method of the battery assembly and effectively improve the assembly efficiency of the battery assembly.

[0048] It can be understood that the installation assembly provided by the embodiment of the utility model, by setting the installation bracket 100 and the cover plate 300, limits at least one group of battery boxes 200 within the accommodating space 130 limited by the installation bracket 100, has a simple structure and low manufacturing cost. When assembly is required, the battery box 200 is first stacked on the first frame 110 and the second frame 120, and then the cover plate 300 is covered on the uppermost battery box 200, and finally the cover plate 300 is connected to at least one of the first frame 110 and the second frame 120 through the connecting component 400 to form an integral battery assembly, and then the battery assembly is connected to the chassis of the vehicle body. Such an arrangement can simplify the installation method of the battery assembly and effectively improve the assembly efficiency of the battery assembly.

[0049] Continue reading Figure 1 In some embodiments of the present invention, the connecting component 400 includes a first connecting member 410 and a second connecting member 420, the first connecting member 410 is connected to one of the first frame 110 and the second frame 120, and the second connecting member 420 is connected to the other of the first frame 110 and the second frame 120, so as to make the overall structure of the battery assembly more solid.

[0050] The first connecting member 410 may be a long screw rod of M16, and the second connecting member 420 may be a connecting member such as a segment bolt, a screw or a rivet.

[0051] The first frame 110 is provided with a first connection hole 140 for connecting the first connection member 410 or the second connection member 420 ; the second frame 120 is provided with a second connection hole 160 for connecting the first connection member 410 or the second connection member 420 .

[0052] For example, when two groups of battery boxes 200 are provided, the two groups of battery boxes 200 are stacked or stacked in the accommodating space 130, and the cover plate 300 is provided on the upper surface of the uppermost battery box 200. Long bolts (i.e., the first connecting member 410) are used to penetrate the cover plate 300, the upper battery box 200, the lower battery box 200, and the second frame 120 in sequence, and nuts are used to lock the end passing through the second frame 120.

[0053] Alternatively, when two groups of battery boxes 200 are provided, the two groups of battery boxes 200 are stacked or stacked in the accommodating space 130, the cover plate 300 is provided on the upper surface of the uppermost battery box 200, and a short bolt (i.e., the second connecting member 420) is used to penetrate the cover plate 300 and the first frame 110 in sequence, and a nut is used to lock the end that penetrates the first frame 110. Among them, an extension portion can be provided on the cover plate 300 to adapt to the position of the first frame 110.

[0054] Alternatively, when two groups of battery boxes 200 are provided, the two groups of battery boxes 200 are stacked or stacked in the accommodating space 130, and the cover plate 300 is provided on the upper surface of the uppermost battery box 200. First, a long bolt (i.e., the first connecting member 410) is used to sequentially penetrate the cover plate 300, the upper battery box 200, the lower battery box 200, and the second frame 120, and a nut is used to tighten the end that penetrates the second frame 120. Secondly, a short bolt (i.e., the second connecting member 420) is used to sequentially penetrate the extension of the cover plate 300 and the first frame 110, and a nut is used to tighten the end that penetrates the extension of the first frame 110.

[0055] In addition, the connecting component 400 can also be an integral structure that mainly plays a connecting role, that is, the connecting component 400 is arranged in an integrated manner. Therefore, the specific form of the connecting component 400 is not limited, as long as it can connect the cover plate 300, the battery box 200 and the mounting bracket 100 together.

[0056] It should also be noted that when the amount of electricity required by the vehicle increases and the number of battery boxes 200 needs to be increased, it is only necessary to adjust the height of the first frame 110, and the width of the second frame 120 remains unchanged. In this way, while accommodating more battery boxes 200 and improving the power density of the battery assembly, when the entire battery assembly is installed on the vehicle body, the width of the vehicle body will not be increased, and it is more practical.

[0057] Continue reading Figure 1 In some embodiments of the present invention, the first frame 110 includes a column 111 and a frame 112 , and the frame 112 is disposed between two adjacent columns 111 .

[0058] The first connection hole 140 is provided on at least one of the column 111 and the frame 112, that is, the first connection hole 140 can be provided on the column 111 or the frame 112. Since the structural strength of the column 111 is greater than the structural strength of the frame 112, it is preferred to provide the first connection hole 140 on the column 111, which can improve the reliability of the connection.

[0059] For example, when a long bolt (ie, the first connecting member 410 ) is used to connect with the second frame 120 , a short bolt is provided on the first frame 110 , and the first connecting hole 140 can be provided on the frame 112 .

[0060] In addition, a first hollow portion 113 is provided on the frame 112, which can not only reduce the weight of the first frame 110, but also be used to dissipate heat for the battery box 200. This prevents the heat generated by the battery assembly during operation from not being dissipated in time, and improves the heat dissipation efficiency of the battery assembly, that is, the battery assembly can not only be cooled by active heat dissipation components such as a water cooling unit, but can also be further cooled by air cooling.

[0061] It should be noted that the structure of the first frame 110 is not limited to the above structure, and any support structure is acceptable as long as it can achieve reliable connection and can achieve the purpose of weight reduction and heat dissipation.

[0062] Continue reading Figure 1 In some embodiments of the present invention, the second frame 120 includes two supporting members 121 and a plurality of beams 122 that are arranged opposite to each other, and the plurality of beams 122 are arranged between the two supporting members at intervals.

[0063] Two adjacent beams 122 and the support members 121 located on both sides of the beams 122 are jointly formed to form a second hollow portion 123. The function of the second hollow portion 123 is the same as that of the first hollow portion 113, that is, the second hollow portion 123 can not only reduce the weight of the second frame 120, but also be used to dissipate heat for the battery box 200. It is prevented that the heat generated by the battery assembly during operation cannot be dissipated in time, and the heat dissipation efficiency of the battery assembly is improved, that is, the battery assembly can not only use active heat dissipation components such as water cooling units to dissipate heat, but also can be further cooled by air cooling.

[0064] The second connection hole 160 is arranged at the intersection of the support member 121 and the cross beam 122. Since the structural strength of the intersection of the support member 121 and the cross beam 122 is higher, opening the second connection hole 160 at this position can improve the connection reliability of the battery assembly and avoid damage to the second connection hole 160.

[0065] Among them, the support member 121 can be a "U"-shaped profile, two support members 121 are arranged opposite to each other, and multiple beams 122 are arranged at intervals along the length direction of the support member 121, similar to the structure of a ladder, and the beams 122 and the support member 121 can be welded and fixed.

[0066] It should be noted that the structure of the second frame 120 is not limited to the above structure, and any support structure is acceptable as long as it can achieve reliable connection and can achieve the purpose of weight reduction and heat dissipation.

[0067] Figure 3 It is a top view of a battery assembly provided by an embodiment of the utility model; Figure 4 It is a side view of a battery assembly provided by an embodiment of the utility model.

[0068] Continue reading Figure 1 and Figure 2 , and also see Figure 3 and Figure 4 In some embodiments of the present invention, at least one of the first frame 110 and the second frame 120 is provided with a connection seat 150 for connecting to the vehicle body. That is, the connection seat 150 for connecting to the vehicle body can be provided on the first frame 110, the connection seat 150 for connecting to the vehicle body can be provided on the second frame 120, or the connection seat 150 for connecting to the vehicle body can be provided on both the first frame 110 and the second frame 120.

[0069] By providing the connection seat 150, the mounting bracket 100 can be detachably connected to the vehicle body, which can not only improve the connection reliability of the battery assembly; compared with directly connecting the first frame 110 or the second frame 120 to the vehicle body, providing the connection seat 150 can increase the installation space and facilitate the connection of the battery assembly.

[0070] Continue reading Figures 1 to 4 In some embodiments of the present invention, the mounting assembly further includes an end plate 500, which is respectively disposed at both ends of the first frame 110 or the second frame 120, and at least one of the first frame 110, the second frame 120 and the cover plate 300 is connected to the end plate 500.

[0071] That is, the end plate 500 can be connected to the cover plate 300, the end plate 500 can also be connected to the first frame 110, and the end plate 500 can also be connected to the second frame 120; in addition, the end plate 500 can be simultaneously connected to any two of the first frame 110, the second frame 120 and the cover plate 300, and the end plate 500 can also be simultaneously connected to the first frame 110, the second frame 120 and the cover plate 300.

[0072] Continue reading Figure 4 A hollow area 510 is provided on the end plate 500 for the liquid cooling interface of the battery box 200 to pass through. The hollow area 510 not only allows the liquid cooling interface of the battery box 200 to pass through, but also plays a role in weight reduction and heat dissipation.

[0073] The end plate 500 is also provided with a plurality of second fixing holes 530 , and the positions and numbers of the second fixing holes 530 are determined according to the objects to be connected. For example, when the end plate 500 and the first frame 110 need to be connected, the second fixing holes 530 are arranged on the side.

[0074] In addition, a flange 520 is provided below the end plate 500 , and a fixing hole is provided on the flange 520 as above, and the end plate 500 is connected to the second frame 120 through the fixing hole.

[0075] Figure 5 is a cross-sectional view of a battery assembly provided by an embodiment of the utility model; Figure 6 yes Figure 5 Enlarged view of part A in the middle.

[0076] Continue reading Figures 1 to 4 , and also see Figure 5 and Figure 6 In some embodiments of the present invention, the mounting assembly further includes a protective plate 600 , which is disposed on one side of the battery box 200 , and at least one of the cover plate 300 and the second frame 120 is connected to the protective plate 600 .

[0077] That is, the protective plate 600 can be a steel plate, which is mainly used to protect the battery box 200 and prevent the battery box 200 from being damaged. Since the commonly used battery box 200 body, that is, the skin of the standard box is mostly thin plate parts, such as SMC, aluminum alloy, DC06, etc., which have poor puncture resistance, a steel plate is provided to protect it in order to improve the overall firmness of the structure.

[0078] The protection plate 600 may be detachably connected to one of the cover plate 300 and the second frame 120 by means of screws, rivets or other fasteners, or may be detachably connected to both the cover plate 300 and the second frame 120 by means of screws, rivets or other fasteners.

[0079] In addition, in some embodiments of the present invention, the mounting assembly may include both the end plate 500 and the protective plate 600 . In this case, at least one of the cover plate 300 , the end plate 500 and the second frame 120 is connected to the protective plate 600 .

[0080] That is, the protective plate 600 can be detachably connected to one of the cover plate 300, the end plate 500 and the second frame 120 by means of screws, rivets and other connecting parts, or can be detachably connected to any two of the cover plate 300, the end plate 500 and the second frame 120 by means of screws, rivets and other connecting parts, or can be detachably connected to the cover plate 300, the end plate 500 and the second frame 120 at the same time by means of screws, rivets and other connecting parts.

[0081] Continue reading Figures 1 to 6 The utility model also provides a battery assembly, which includes at least one battery box 200 and the above-mentioned installation assembly, and at least one battery box 200 is arranged in the accommodating space of the installation assembly.

[0082] At least one group of battery boxes 200 is horizontally arranged in the accommodating space 130, and each battery box 200 includes a box body 210 and a battery module 220, and the battery module 220 is arranged in the box body 210; wherein, when there are at least two battery boxes 200, the battery boxes 200 can be stacked or layered in the accommodating space 130 in the thickness direction thereof.

[0083] Continue reading Figure 5 and Figure 6 In some embodiments of the present invention, the box body 210 is an aluminum alloy profile, and the box body 210 includes a bottom plate 211 and a side plate 212. The bottom plate 211 and the side plate 212 are both provided with a hollow structure, which can achieve the purpose of weight reduction.

[0084] The thickness of the side panel 212 is greater than that of the bottom panel 211, and the thickness of the side panel 212 is greater than 20 mm, so that the side panel 212 can directly bear the weight of the upper battery box 200. Therefore, when multiple groups of battery boxes 200 are arranged, the battery boxes 200 can be stacked or layered in the accommodating space 130 along their own thickness direction, and it can be avoided to set a fixed beam between two adjacent groups of battery boxes 200, so as to ensure that the ground clearance is increased by 50 mm.

[0085] In the prior art, when multiple battery boxes 200 are stacked, a fixed beam needs to be set between two adjacent battery boxes 200, so that there is a gap of 45mm between two adjacent battery boxes 200, and the overall height of the installation frame is about 658mm, resulting in a small ground clearance. The structure of the utility model can increase the ground clearance. At the same time, the thickness of the side plate 212 is relatively large, and it can directly bear the weight, so that the upper battery box 200 can be directly stacked on the lower battery box 200, without the need to set other fixed beams and other structures between two adjacent battery boxes 200, and can also simplify the installation method and improve the installation efficiency.

[0086] The utility model also provides a vehicle, comprising a vehicle body and the above-mentioned battery assembly, wherein the battery assembly is laterally mounted on the vehicle body.

[0087] When the battery assembly is hung on the chassis of the vehicle body, the battery assembly provided by the embodiment of the utility model is used for easy installation. When multiple battery boxes 200 are needed, multiple battery boxes 200 can be stacked to increase the energy density of the battery assembly without affecting the width of the vehicle.

[0088] The vehicle may include commercial vehicles, which may include buses, trucks, semi-trailer tractors, incomplete buses and incomplete trucks, etc. For example, common commercial vehicle models include pickup trucks, mini trucks, light trucks, micro buses, dump trucks, trucks, tractors, trailers, special vehicles, etc.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
