[0072] The following will be described in combination withFigures 1-11 The technical solutions provided by the present application are described in more detail. The description of the exemplary embodiments is merely illustrative, and in no way limits the present disclosure and its applications or uses. The present disclosure can be implemented in many different forms, and is not limited to the embodiments introduced here. These embodiments are provided to make the present disclosure thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that: unless otherwise specified, the relative arrangement of components and steps, the composition of materials, numerical expressions and values set forth in these embodiments should be interpreted as merely exemplary, and not as a limitation.

[0073] The "first", "second", and similar words used in the present disclosure do not represent any order, number or importance, but are only used to distinguish different parts. "Include" or "contain" and similar words mean that the elements before the word cover the elements listed after the word, and do not exclude the possibility of also covering other elements.

[0074] In the present disclosure, when it is described that a specific device is located between a first device and a second device, there can be an intervening device between the specific device and the first device or the second device, or there can be no intervening device. When it is described that a specific device is connected to other devices, the specific device can be directly connected to other devices without an intervening device, or it can not be directly connected to other devices with an intervening device.

[0075] All terms used in the present disclosure, including technical terms or scientific terms, have the same meaning as understood by those skilled in the art to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted to have meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or excessively formalized sense, unless specifically defined here.

[0076] Techniques, methods and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods and devices are considered part of the specification.

[0077] The sizes of the various parts shown in the drawings are not drawn in actual proportion. Common structural elements or the same kind of structural elements are given the same reference numerals in the various drawings, and repeated description of them is appropriately omitted.

[0078] In the description of the specific embodiments hereinafter, for the convenience of explanation, the width direction of the battery frame is defined as the X direction, the length direction of the battery frame is defined as the Y direction, and the height direction of the battery frame is defined as the Z direction.

[0079] The inventor finds that at least the following problems exist in the prior art: In the wave of electrification of logistics equipment, the standardized design of the battery frame is becoming a key breakthrough for the industry's pain points. The traditional "customized fixed structure" battery frame can only adapt to a single capacity battery pack, resulting in the need for independent development of corresponding frames for different equipment, which not only increases the cost of a single project, but also prolongs the research and development cycle. In addition, the mode of independent development of each equipment cannot meet the rapid iteration demand of equipment. In addition, the weight of the battery pack is very large, and if multiple battery packs are simply assembled together, the installation and maintenance of the battery pack are too difficult. Therefore, the present application provides the following technical solutions to solve the problems existing in the prior art battery frame.

[0080] Referring to Figure 1 The embodiment of the present application provides a battery frame, which comprises a first support frame assembly 1, a second support frame assembly 2 and a third support frame assembly 3. The first support frame assembly 1 comprises a first opening 10 which can be opened and closed, and the first opening 10 is configured to allow the first battery pack to enter and exit the first support frame assembly 1. The second support frame assembly 2 comprises a second opening 20 which can be opened and closed, and the second opening 20 is configured to allow the second battery pack to enter and exit the second support frame assembly 2. The second support frame assembly 2 is detachably fixedly connected with the first support frame assembly 1. The third support frame assembly 3 comprises a third opening 30 which can be opened and closed, and the third opening 30 is configured to allow the third battery pack to enter and exit the third support frame assembly 3. The third support frame assembly 3 is detachably fixedly connected with the second support frame assembly 2; wherein the second support frame assembly 2 is located between the first support frame assembly 1 and the third support frame assembly 3. Wherein the first opening 10 is located on the side of the first support frame assembly 1 away from the second support component assembly, the second opening 20 is located on the top of the second support frame assembly 2, and the third opening 30 is located on the side of the third support component assembly away from the second support frame assembly 2.

[0081] The first opening 10 of the first support frame assembly 1, the second opening 20 of the second support frame assembly 2 and the third opening 30 of the third support frame assembly 3 are all openable and closable. When the battery pack needs to be placed into or taken out of the first support frame assembly 1, the second support frame assembly 2 and the third support frame assembly 3, the corresponding opening is opened, and after the operation of storing or taking out the battery pack is completed, the corresponding opening is closed.

[0082] Continuing to refer to Figure 1 In some embodiments, the number of second support frame assemblies 2 is at least two, and each second support frame assembly 2 is arranged side by side. The more the number of second support frame assemblies 2, the more the number of battery packs that can be placed in the second support frame assemblies 2. The more the total number of battery packs carried by the battery frame, the larger the total battery capacity.

[0083] Continuing to refer to Figure 1In some embodiments, the height of the second support frame assembly 2 is lower than the height of each of the first support frame assembly 1 and the third support frame assembly 3. The battery frame is high on both sides and low in the middle in the X direction. The layout of high on both sides and low in the middle can lower the center of gravity of the battery pack and make it biased to the bottom, thereby reducing the overall height of the center of mass of the battery frame and the battery pack. When the new energy vehicle or the logistics equipment encounters bumps during travel, this structure can reduce the shaking amplitude of the battery pack and reduce the risk of cell misalignment caused by inertial force. The middle recessed area forms a "flexible buffer zone". When the battery frame and the battery pack are subjected to a lateral impact (such as a side collision), the low recessed part in the middle can absorb energy through structural deformation to avoid direct impact load on the high stacked area on both sides.

[0084] The specific implementation of each of the first support frame assembly 1, the second support frame assembly 2, and the third support frame assembly 3 will be described in detail below.

[0085] Referring to Figures 2-4 In some embodiments, the first support frame assembly 1 includes a first support frame 11 (see Figure 1 , Figures 2-4 not shown), a first U-shaped assembly 12, and a second stand 13. The first U-shaped assembly 12 includes a first stand 121, a first cross beam 122, a second cross beam 123, and a plurality of first mounting members 124; the first cross beam 122 is fixedly connected to one end of the first stand 121; the second cross beam 123 is fixedly connected to the other end of the first stand 121; the second cross beam 123 is spaced apart from and parallel to the first cross beam 122; the first cross beam 122 and the second cross beam 123 each have a plurality of first mounting members 124 fixed thereto, and each first mounting member 124 is arranged intersecting the first cross beam 122. The second stand 13 is arranged spaced apart from the first stand 121, and the second stand 13 is detachably fixedly connected to the first cross beam 122 and the second cross beam 123. Among them, the first U-shaped assembly 12 and the second stand 13 are both mounted on the first support frame 11.

[0086] The first support frame 11 is a rectangular frame formed by welding and / or bolting a plurality of rod members, the first U-shaped assembly 12 and the second stand 13 surround a first through hole, and the first support frame 11 passes through the first through hole. Along the Y direction, i.e. the length direction of the first support frame 11, a plurality of groups of first U-shaped assemblies 12 and second stands 13 are arranged at intervals. The rectangular frame is supported by the plurality of groups of first U-shaped assemblies 12 and second stands 13 dispersed in multiple groups. The bottom edge of the rectangular frame and the first mounting members 124 of the first U-shaped assembly 12 jointly support the battery pack located in the rectangular frame, and the first mounting members 124 are also fixedly connected to the battery pack, so that the battery pack is better and more stably fixed, positioned and supported.

[0087] Since the battery pack can be taken out and put in via the first opening 10 of the first support frame assembly 1, the side of the first support frame 11 corresponding to the connection of the first U-shaped assembly 12 and the second column 13 cannot be welded, but bolted. When the battery pack needs to be taken out and put in, the part of the beam of the first support frame 11 is taken off first, and then the first U-shaped assembly 12 and the second column 13 are disassembled, so that the first opening 10 of the first support frame assembly 1 is formed, and in the position shown by the side A in the figure, the battery pack can be conveniently put into and taken out from the inside of the first support frame assembly 1 via the first opening 10. Figure 1

[0088] Continuing to refer to Figure 2 and Figure 3 In some embodiments, the first support frame assembly 1 further comprises a first connecting part 14, a second connecting part 15, a third connecting part 16 and a fourth connecting part 17. The first connecting part 14 is located at the end of the first cross beam 122 away from the first column 121, and is fixedly connected with or integrated with the first cross beam 122. The second connecting part 15 is located at the end of the second cross beam 123 away from the first column 121, and is fixedly connected with or integrated with the second cross beam 123. The third connecting part 16 is located at the second column 13, and is fixedly connected with or integrated with the second column 13; the third connecting part 16 is detachably fixedly connected with the first connecting part 14. The fourth connecting part 17 is located at the second column 13, and is fixedly connected with or integrated with the second column 13; the fourth connecting part 17 is detachably fixedly connected with the second connecting part 15.

[0089] The structures of the first connecting part 14, the second connecting part 15, the third connecting part 16 and the fourth connecting part 17 can be the same, and specifically can be an ear plate provided with a plurality of bolt holes, and the bolts are passed through the bolt holes to realize the detachable connection of the first connecting part 14 and the third connecting part 16 and the detachable connection of the second connecting part 15 and the fourth connecting part 17.

[0090] Continuing to refer to Figure 3 The first connecting part 14 is integrated with the first cross beam 122 and the first mounting member 124 located at the most edge of the first cross beam 122, and specifically can be cast into shape. Each first mounting member 124 is provided in the shape of a rod, and both ends of each first mounting member 124 are provided with a first through hole. A second through hole (not shown in the figure) is correspondingly provided on the battery pack, and the first through hole, the second through hole and the bolts and the like connecting members are used to realize the detachable fixed connection of the battery pack and the first support frame assembly 1. Each first support frame assembly 1 can be installed and fixed with one layer of battery pack, and specifically can be one or more battery packs, which is determined according to the specific structure and size of the battery pack.

[0091] Continuing to refer to Figure 3 ​The first U-shaped assembly 12 further comprises a first intermediate connecting part 125 and a second intermediate connecting part 126. The first intermediate connecting part 125 and the second intermediate connecting part 126 are fixedly connected with the first vertical column 121 or are integrated, and can be cast into shape. Correspondingly, the first C-shaped support 22 (to be described later) of the second support assembly 2 is provided with a third intermediate connecting part 221, and the second C-shaped support 23 (to be described later) of the second support assembly 2 is provided with a fourth intermediate connecting part 222.

[0092] After the first support assembly 1 and the second support assembly 2 are placed side by side, the first intermediate connecting part 125 and the third intermediate connecting part 221 are formed in an upper-lower stacking manner. The first intermediate connecting part 125 and the third intermediate connecting part 221 are each provided with a first connecting through hole a, and the first intermediate connecting part 125 and the third intermediate connecting part 221 are fixed by a connecting member such as a bolt passing through the first connecting through hole a, thereby realizing detachable fixed connection of the first support assembly 1 and the second support assembly 2.

[0093] The second intermediate connecting part 126 and the fourth intermediate connecting part 222 can be specifically ear plates, and each is provided with a second connecting through hole b. After the first support assembly 1 and the second support assembly 2 are placed side by side, the first intermediate connecting part 125 and the third intermediate connecting part 221 are formed in a left-right adhering manner. The second intermediate connecting part 126 and the fourth intermediate connecting part 222 are fixed by a connecting member such as a bolt passing through the second connecting through hole b, thereby realizing detachable fixed connection of the first support assembly 1 and the second support assembly 2.

[0094] It can be seen that in the above connection mode, the first support assembly 1 and the second support assembly 2 simultaneously adopt upper-lower adhering fixation and left-right adhering fixation in the plane, that is, positioning and fixation are realized in the Z direction and the X direction at the same time, the installation of the first support assembly 1 and the second support assembly 2 is more accurate, the realization mode of positioning and fixation is ingenious, the occupied space is extremely small, and the fixation and positioning effect is good.

[0095] Referring to Figure 1 , Figures 5-7 In some embodiments, the second support assembly 2 comprises a second support 21, a first C-shaped support 22, and a second C-shaped support 23. The second C-shaped support 23 is detachably fixedly connected with the first C-shaped support 22, and the second C-shaped support 23 and the first C-shaped support 22 form a second through hole 200 by splicing. The second support 21 passes through the second through hole 200, and the second support 21 is connected with the first C-shaped support 22 and the second C-shaped support 23. Along the length direction of the second support 21, that is, Figure 1The X direction is shown, and the first C-shaped support 22 and the second C-shaped support 23 are arranged in a dispersed manner, and the first C-shaped support 22 and the second C-shaped support 23 jointly support the second support frame 21. The first C-shaped support 22 and the second C-shaped support 23 are each fixed with a plurality of third mounting members 24. Among them, the first C-shaped support 22 and the second C-shaped support 23 are both mounted on the second support frame 21. The second support frame 21, the third mounting member 24 of the first C-shaped support 22, and the third mounting member 24 of the second C-shaped support 23 jointly support the battery pack. The third mounting member 24 is configured as a rod. The battery pack is detachably fixedly connected with the third mounting member 24.

[0096] The second support frame 21 is a rectangular frame formed by welding or bolt connection of angle steels. The angle steel at the top of the second support frame 21 is detachable. When it is necessary to place the battery pack inside the second support frame 21, the angle steel at the top of the second support frame 21 is first disassembled, and then the first C-shaped support 22 at the top is disassembled. The second C-shaped support 23 at the bottom does not need to be disassembled, at this time a second opening 20 is formed at the top of the second support frame assembly 2. The battery pack can be conveniently placed inside the second support frame assembly 2 through the second opening 20, and the battery pack can also be conveniently taken out.
