[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] Reference below Figure 1-Figure 15 A prefabricated battery compartment 100 according to an embodiment of the present invention is described.

[0039] like Figure 1-Figure 6 As shown, the battery prefabricated compartment 100 according to the embodiment of the utility model comprises: a box body 10, a tray assembly 20 and a guide rail 30. The box body 10 has a receiving cavity 101; the tray assembly 20 is used to receive a battery cluster, and the battery cluster includes a plurality of stacked battery packs. The bottom of the tray assembly 20 is provided with a roller assembly 21; the guide rail 30 is provided at the bottom of the receiving cavity 101, and the guide rail 30 is provided along a first direction (such as Figure 5 The roller assembly 21 extends in the front-to-rear direction as shown, and the guide rail 30 is in rolling engagement with the roller assembly 21.

[0040] In this embodiment, the battery cluster is accommodated in the tray assembly 20, so that when the battery prefabricated compartment 100 is assembled, multiple battery packs can be assembled and installed in the accommodating cavity 101 as a whole through the tray assembly 20, so that the battery prefabricated compartment 100 is more convenient and saves trouble during assembly. The battery cluster is arranged in the tray assembly 20, which can greatly reduce the number of structural parts used for supporting and fixing in the box body 10, so that the box body 10 has less work to do during production, so that the battery prefabricated compartment 100 has higher production efficiency during production and manufacturing, and the production cost is greatly reduced.

[0041] In this embodiment, the battery cluster refers to a battery unit composed of multiple battery packs connected in series, in parallel, or in a series-parallel hybrid manner to achieve higher voltage, larger capacity, or more complex functional requirements. In this embodiment, multiple battery packs stacked in the battery cluster are arranged in the tray assembly 20, which can facilitate the assembly of the battery prefabricated compartment 100, so that the multiple battery packs can be arranged more compactly, and the supporting structure in the accommodating cavity 101 is reduced, so that the space in the battery prefabricated compartment 100 can be more fully utilized.

[0042] It can be understood that since a plurality of battery packs are arranged in the tray assembly 20, the total volume and total mass of the tray assembly 20 are relatively heavy. In the present embodiment, a roller assembly 21 is arranged at the bottom of the tray assembly 20, and a guide rail 30 is arranged in the accommodating cavity 101 to roll with the roller assembly 21, so that when the tray assembly 20 is assembled into the accommodating cavity 101, the tray assembly 20 can cooperate with the guide rail 30 through the roller assembly 21, and can be stably and reliably assembled into the accommodating cavity 101 along the first direction. The roller assembly 21 converts hard sliding into rolling, so that the friction resistance received by the tray assembly 20 during the movement is greatly reduced, so that the tray assembly 20 can be moved lightly and easily for assembly, and then the battery cluster can be conveniently and easily assembled into the box body 10.

[0043] In this embodiment, a guide rail 30 is provided at the bottom of the accommodating cavity 101 to cooperate with the roller assembly 21, which can provide good support for the tray assembly 20, so that the tray assembly 20 can be stably and conveniently accommodated in the accommodating cavity 101 of the box body 10, with a simple structure and easy use.

[0044] According to the battery prefabricated compartment 100 of the embodiment of the utility model, by arranging multiple battery packs of the battery cluster in the tray assembly 20, the multiple battery packs can be assembled as a whole into the accommodating cavity 101 of the box body 10, thereby reducing the number of structural parts in the box body 10, so that the battery prefabricated compartment 100 has less workload and higher production efficiency during production. A roller assembly 21 is arranged at the bottom of the tray assembly 20, and a guide rail 30 is arranged in the accommodating cavity 101 of the box body 10. The roller assembly 21 cooperates with the guide rail 30, so that the tray assembly 20 can be conveniently and easily assembled into the accommodating cavity 101 of the box body 10, so that the battery cluster can be conveniently and easily assembled into the battery prefabricated compartment 100.

[0045] In some embodiments of the present invention, Fig. 9 and Fig.12 As shown, the tray assembly 20 may have at least two Fig. 9 The roller assemblies 21 are arranged at intervals in a left-right direction (as shown in the second direction), and the second direction is perpendicular to the first direction. The roller assembly 21 may include: a fixing member 211 and a roller group 212. The fixing member 211 extends along the first direction and is detachably mounted on the bottom of the tray assembly 20; the roller group 212 is mounted on the fixing member 211, and a plurality of roller groups 212 are provided. The plurality of roller groups 212 are arranged along the first direction and are in rolling cooperation with the guide rail 30.

[0046] In this embodiment, at least two roller assemblies 21 are arranged in the second direction, that is, two or more roller assemblies 21 can be arranged, and the roller assemblies 21 are arranged at intervals in the second direction, and can cooperate with the guide rails 30 to stably and reliably support and fix the tray assembly 20, so that the tray assembly 20 can be stably assembled in the accommodating cavity 101.

[0047] In this embodiment, the roller assembly 21 is provided with a fixing member 211 and a roller group 212. The fixing member 211 extends along a first direction and is installed at the bottom of the tray assembly 20. The structure is simple, and it is convenient for the installation and fixation of multiple roller groups 212, so that the roller group 212 is stably and reliably connected to the tray assembly 20. To a certain extent, the supporting effect of the roller assembly 21 on the tray assembly 20 can be improved, so that the tray assembly 20 can be more stably supported.

[0048] In this embodiment, a plurality of roller groups 212 are provided, and the plurality of roller groups 212 are arranged along the first direction and roll in cooperation with the guide rail 30, so that the tray assembly 20 can obtain the cooperation and support of the roller group 212 and the guide rail 30 within the extension range of the first direction, so that the tray assembly 20 can obtain more stable support, so that when the tray assembly 20 is assembled into the accommodating cavity 101 along the first direction, the plurality of roller groups 212 can roll in cooperation with the guide rail 30 stably, so that the tray assembly 20 can be assembled into the accommodating cavity 101 more stably and conveniently. For example, the roller groups 212 can be provided with two, three, four, five, six, etc., and the number of roller groups 212 can be reasonably set according to needs.

[0049] In one embodiment of the present invention, Fig.10 As shown, the roller assembly 212 may include: a mounting frame 2121 and a roller 2122 , the mounting frame 2121 is connected to the fixing member 211 , the roller 2122 is rotatably mounted on the mounting frame 2121 , and the roller 2122 is in rolling cooperation with the guide rail 30 .

[0050] In this embodiment, the roller group 212 is provided with a mounting frame 2121 and a roller 2122. The mounting frame 2121 is fixedly connected to the fixing member 211, so that the roller 2122 can be conveniently and stably mounted on the fixing member 211, and the roller 2122 is rollingly matched with the guide rail 30. Specifically, the roller 2122 can rotate along the first direction around the axis of the rotation axis fixed to the mounting frame 2121, so that when the tray assembly 20 is assembled into the accommodating cavity 101, the roller 2122 rotates along the extension direction of the guide rail 30, thereby driving the rolling assembly to move along the first direction, and then the tray assembly 20 moves along the first direction until it is completely in the accommodating cavity 101. In this embodiment, the mounting frame 2121 and the roller 2122 are provided in the roller group 212, which has a simple structure and is easy to use.

[0051] In some examples of the present invention, Fig. 9 and Fig.13 As shown, the cross-section of the fixing member 211 can be U-shaped, and the fixing member 211 is formed with a mounting groove 2111. The mounting frame 2121 is installed in the mounting groove 2111. In the second direction, the opening of the mounting groove 2111 faces the guide rail 30, and the guide rail 30 partially extends into the mounting groove 2111 and cooperates with the roller 2122.

[0052] In this embodiment, the cross section of the fixing member 211 is set to be U-shaped, and the fixing member 211 is formed with a mounting groove 2111 with an opening facing the guide rail 30. The structure is simple, which facilitates the installation and fixing of the mounting frame 2121 and the fixing member 211, so that the overall structure of the mounting frame 2121 and the fixing member 211 is relatively compact. The opening of the mounting groove 2111 faces the guide rail 30, which can facilitate the guide rail 30 to extend into the mounting groove 2111 and cooperate with the roller 2122, so that the assembly of the roller assembly 21 and the guide rail 30 is relatively convenient and easy, and the structure of the roller assembly 21 and the guide rail 30 is more compact. The roller 2122 can cooperate well with the guide rail 30, the mounting frame 2121 and the fixing member 211 in the up and down directions to support the tray assembly 20, so that the tray assembly 20 can be more stably and reliably installed in the accommodating cavity 101. Optionally, the fixing member 211 can be a channel steel member.

[0053] In one example of the present invention, reference Fig.10 As shown, in the first direction, the two roller groups 212 located at the two ends of the guide rail 30 form an end roller group, and the multiple roller groups 212 between the two end roller groups form a middle roller group. Two rollers 2122 are provided in the end roller group, and the two rollers 2122 are arranged at intervals in the up and down directions. The guide rail 30 has a guide portion 31 extending along the first direction, and the two rollers 2122 are respectively rollingly matched with the two side surfaces of the guide portion 31 in the up and down directions. The structure of the middle roller group is the same as that of the end roller group, or the middle roller group is provided with a roller 2122, and the roller 2122 is rollingly matched with one side surface of the guide portion 31 in the up and down directions.

[0054] In this embodiment, two rollers 2122 are arranged in an upper and lower interval in the roller group 212. The two rollers 2122 respectively roll with the two side surfaces of the guide portion 31, so that when the tray assembly 20 moves, the two rollers 2122 can increase the contact area between the roller group 212 and the guide rail 30, so that the roller group 212 and the guide rail 30 cooperate more reliably, and the rollers 2122 rotate more stably, so that the roller assembly 21 can move more stably along the guide rail 30, so that the tray assembly 20 can move smoothly along the first direction. After the tray assembly 20 is assembled in place, the two rollers 2122 can be clamped on the guide rail 30, so that the roller assembly 21 can better cooperate with the guide rail 30 to support the tray assembly 20 to a certain extent.

[0055] In this embodiment, the two roller groups 212 at both ends of the guide rail form an end roller group, and the roller group between the two end roller groups forms a middle roller group. The middle roller group can have the same structure as the end roller group, that is, the end roller group and the middle roller group are both provided with two rollers 2122, so that the multiple roller groups 212 can always stably roll with the guide portion 31 of the guide rail 30 through the two rollers 2122 in the first direction, so that the roller assembly 21 can more stably and reliably drive the tray assembly 20 to move along the first direction.

[0056] The middle roller group may also be provided with only one roller 2122. The roller 2122 may be arranged on the upper surface of the guide portion 31 in the up-down direction. The roller 2122 may also be arranged on the lower surface of the guide portion 31 in the up-down direction. In this way, the roller group 212 may have fewer parts when meeting the use requirements, thereby reducing the cost of the roller assembly 21 to a certain extent, thereby reducing the cost of the battery prefabricated compartment 100.

[0057] In some embodiments of the present invention, reference Figure 1-Figure 10 As shown, the tray assembly 20 may be provided in plurality, and the plurality of tray assemblies 20 are arranged along the second direction, and the guide rail 30 forms a guide portion 31 on one side or both sides of the second direction. When the guide portions 31 are formed on both sides of the guide rail 30, the guide rail 30 is suitable for rolling cooperation with two adjacent roller assemblies 21.

[0058] In this embodiment, multiple tray assemblies 20 are provided, which can well meet the use requirements of the battery prefabricated compartment 100, so that the battery prefabricated compartment 100 can have a larger capacity to be suitable for more application scenarios. In this embodiment, the guide rail 30 is formed with a guide portion 31 on one side or both sides of the second direction. The guide rail 30 can form the guide portion 31 on one side of the second direction, or the guide rail 30 can form the guide portion 31 on both sides.

[0059] It can be understood that when multiple tray assemblies 20 are arranged along the second direction, the roller assembly 21 at the bottom of the tray assembly 20 is also arranged along the second direction accordingly. In this embodiment, two guide portions 31 are provided on the guide rail 30, so that in two adjacent tray assemblies 20, two adjacent roller assemblies 21 can share the same guide rail 30, thereby reducing the number of guide rails 30 used, making the arrangement of multiple tray assemblies 20, roller assemblies 21 and guide rails 30 more compact and reasonable, reducing the number of parts of the battery prefabricated cabin 100, thereby reducing the workload and cost of the battery prefabricated cabin 100 during processing and production.

[0060] In one embodiment of the present invention, reference Figure 6 and Fig.10As shown, the guide rail 30 may be a channel steel member or an I-beam steel member, and a guide portion 31 is formed at the upper end of the guide rail 30. In this embodiment, the guide rail 30 is set as a channel steel member or an I-beam steel member, and a guide portion 31 is formed at the upper end of the guide rail 30. Specifically, when the guide rail 30 is a channel steel member, the opening of the groove of the guide rail 30 is arranged in the horizontal direction, and the upper end of the guide rail 30 is formed with the guide portion 31 on one side in the second direction. When the guide rail 30 is an I-beam steel member, the upper end of the guide rail 30 is formed with the guide portions 31 on both sides in the second direction.

[0061] In this embodiment, the guide rail 30 is set as a channel steel part or an I-beam steel part, which is easy to manufacture, has good bending and torsion resistance, high structural strength, and can play a good supporting role, so that the roller assembly 21 can stably and reliably move along the guide rail 30, and the tray assembly 20 can be stably supported on the guide rail 30 through the roller assembly 21. The groove structure in the channel steel part or the I-beam steel part can provide a good avoidance space when the roller assembly 21 and the guide rail 30 are assembled, so that the roller assembly 21 and the guide rail 30 are easy and convenient to use in combination.

[0062] In some embodiments of the present invention, reference Figure 3-Figure 6 As shown, the box body 10 may include: a frame 11 and a door panel 12, the frame 11 includes two side beams 111 extending along the second direction, the two side beams 111 are arranged at intervals along the first direction, the two ends of the guide rail 30 are respectively mounted on the side beams 111, and the door panel 12 is openably mounted on the frame 11 and is located on one side of the box body 10 in the first direction; the battery prefabricated cabin 100 may also include a limit plate 40, the limit plate 40 is arranged on the side of the tray assembly 20 facing the door panel 12, and the limit plate 40 is detachably connected to the side beams 111 and the tray assembly 20.
