[0035] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Below, reference is made to Figures 1 - 3 Describe the tray 100 according to the embodiments of the present invention. The tray 100 includes: a tray body 10 and an adjusting assembly 20.

[0036] Specifically, as Figure 1 and Figure 2 shown, the tray body 10 includes a first accommodating portion 11 and a second accommodating portion 12; the adjusting assembly 20 is disposed between the first accommodating portion 11 and the second accommodating portion 12, and the adjusting assembly 20 is movably engaged with at least one of the first accommodating portion 11 and the second accommodating portion 12.

[0037] In this embodiment, the tray body 10 includes a first accommodating portion 11 and a second accommodating portion 12 arranged along the length direction of the tray body 10. The first accommodating portion 11 and the second accommodating portion 12 form the tray body 10 for accommodating battery cells. One end of the first accommodating portion 11 and one end of the second accommodating portion 12 are arranged adjacent to each other along the length direction of the tray body 10, and the other end of the first accommodating portion 11 and the other end of the second accommodating portion 12 extend away from each other along the length direction of the tray body 10 respectively. The adjusting assembly 20 is disposed between the adjacent ends of the first accommodating portion 11 and the second accommodating portion 12, and the adjusting assembly 20, the first accommodating portion 11 and the second accommodating portion 12 are all aligned along the length direction of the tray body 10. One end of the adjusting assembly 20 is fixedly connected to one of the first accommodating portion 11 and the second accommodating portion 12, and the other end of the adjusting assembly 20 is movably connected to the other of the first accommodating portion 11 and the second accommodating portion 12. The tray body 10 is adapted to accommodate battery cells, and the adjusting assembly 20 is adapted to adjust the distance between the first accommodating portion 11 and the second accommodating portion 12. For example, the said one end of the adjusting assembly 20 is fixedly connected to the first accommodating portion 11, and by adjusting the position of the adjusting assembly 20 and the second accommodating portion 12, the position adjustment of the first accommodating portion 11 and the second accommodating portion 12 in the length direction of the tray body 10 is realized, so that the tray 100 can be adjusted accordingly according to the required number of battery cells.

[0038] According to the tray 100 of the embodiment of the present utility model, by arranging the adjusting component 20 between the first accommodating part 11 and the second accommodating part 12, the adjusting component 20 can connect the first accommodating part 11 and the second accommodating part 12 and adjust the distance between the first accommodating part 11 and the second accommodating part 12, so that the size of the tray 100 can be changed, facilitating the accommodation of different numbers of battery cells, achieving the purpose of diversified use of the tray 100, improving the versatility of the tray 100 while reducing unnecessary mold opening consumption and saving production costs.

[0039] According to some embodiments of the present utility model, as Figure 3 shown, the adjusting component 20 includes: at least one first adjusting member 21, the first adjusting member 21 extends along the length direction of the tray body 10, one end of the first adjusting member 21 is adapted to be detachably connected to one of the first accommodating part 11 and the second accommodating part 12, and the other end of the first adjusting member 21 is in guiding cooperation with the other of the first accommodating part 11 and the second accommodating part 12.

[0040] For example, one end of the first adjusting member 21 is detachably connected to the end of the first accommodating part 11 adjacent to the second accommodating part 12, the other end of the first adjusting member 21 extends along the length direction of the tray body 10 in a direction away from the first accommodating part 11, and the other end of the first adjusting member 21 is movably cooperated with the end of the second accommodating part 12 adjacent to the first accommodating part 11. When adjusting the length of the tray body 10, through the guiding cooperation between the second accommodating part 12 and the first adjusting member 21, the second accommodating part 12 can move along the first adjusting member 21 towards the first accommodating part 11 to realize the design of tray bodies 10 of different specifications. The first adjusting member 21 is a tubular structural member, and the cross-sectional shape of the first adjusting member 21 includes but is not limited to a polygon or a circle.

[0041] Thus, one end of the first adjusting member 21 is detachably connected to one of the first accommodating part 11 and the second accommodating part 12, and the other end forms a guiding cooperation with the other of the first accommodating part 11 and the second accommodating part 12, which can improve the assembly accuracy of the first adjusting member 21 on the second accommodating part 12, facilitate the adjustment of the matching length of the first adjusting member 21 on the second accommodating part 12, enhance the practicability of the first adjusting member 21, and the structure of the first adjusting member 21 is simple. At the same time, it is convenient for the assembly and disassembly of the first adjusting member 21 on the tray body 10, improving the working efficiency of the adjusting component 20.

[0042] According to some embodiments of the present utility model, as Figure 3 shown, at least one first accommodating cavity is respectively formed at the ends of the first accommodating part 11 and the second accommodating part 12 adjacent to each other, and both ends of the first adjusting member 21 are respectively fitted in the opposite first accommodating cavities of the first accommodating part 11 and the second accommodating part 12.

[0043] The first accommodation cavity is respectively located at one end where the first accommodation part 11 and the second accommodation part 12 are adjacent to each other. The first accommodation cavity provided in the first accommodation part 11 and the second accommodation part 12 is adapted to commonly accommodate the first adjusting member 21. Both ends of the first adjusting member 21 respectively form a fit with the first accommodation cavity in the first accommodation part 11 and the second accommodation part 12. The cross-sectional shape of the first accommodation cavity is adapted to the cross-sectional shape of the first adjusting member 21. For example, the cross-sectional shape of the first adjusting member 21 is rectangular, and the cross-sectional shape of the first accommodation cavity is rectangular.

[0044] Thus, both ends of the first adjusting member 21 are respectively fitted in the opposite first accommodation cavities of the first accommodation part 11 and the second accommodation part 12, which can facilitate the fixation of the first adjusting member 21 on the first accommodation part 11 and the second accommodation part 12, and facilitate the guiding fit of the first accommodation part 11 and the second accommodation part 12 along the length direction of the first adjusting member 21, so as to be suitable for precisely adjusting the size of the tray 100. At the same time, the occupied space of the first adjusting member 21 in the tray 100 is saved, and the sealing performance of the tray 100 is increased.

[0045] According to some embodiments of the present invention, as Figure 3 shown, there are a plurality of first adjusting members 21, and the plurality of first adjusting members 21 are arranged at intervals along the height direction of the tray body 10; there are a plurality of first accommodation cavities, and the plurality of first adjusting members 21 respectively cooperate with the plurality of first accommodation cavities.

[0046] That is, the plurality of first adjusting members 21 all extend along the length direction of the tray body 10 respectively, and the plurality of first adjusting members 21 are arranged at intervals along the height direction of the tray body 10. There are a plurality of first accommodation cavities for cooperating with the first adjusting members 21. The arrangement positions and arrangement manners of the plurality of first accommodation cavities are the same as those of the plurality of first adjusting members 21, and the plurality of first accommodation cavities provided on the first accommodation part 11 and the second accommodation part 12 correspond one by one along the length direction of the tray body 10, so as to facilitate the first adjusting members 21 to be arranged in two first accommodation cavities opposite to each other along the length direction of the tray body 10.

[0047] Thus, by providing a plurality of first adjusting members 21, and the plurality of first adjusting members 21 are arranged at intervals along the height direction of the tray body 10, the structural strength of the connection between the first accommodation part 11 and the second accommodation part 12 can be improved, and the tray 100 can be prevented from being bent or broken when subjected to an external impact force during the connection of a single first adjusting member 21. The simultaneous arrangement of the plurality of first adjusting members 21 can improve the structural strength of the tray 100.

[0048] According to some embodiments of the present invention, as Figure 3As shown, the first accommodating portion 11 includes a first side plate 111, the second accommodating portion 12 includes a second side plate 121, the first side plate 111 and the second side plate 121 face each other along the length direction of the tray body 10, and a first accommodating cavity is formed in each of the first side plate 111 and the second side plate 121.

[0049] In this embodiment, there are two first side plates 111 and two second side plates 121. The two first side plates 111 are spaced apart from each other along the width direction of the tray body 10 on both sides of the first accommodating portion 11, and the two second side plates 121 are spaced apart from each other along the width direction of the tray body 10 on both sides of the second accommodating portion 12. That is, a plurality of first accommodating cavities are provided in the first side plates 111 and the second side plates 121 provided on both sides of the first accommodating portion 11 and the second accommodating portion 12. A plurality of first adjusting members 21 are disposed in two first accommodating cavities facing each other along the length direction of the tray body 10 to connect the first accommodating portion 11 and the second accommodating portion 12 and realize the adjustment between the first accommodating portion 11 and the second accommodating portion 12, facilitating the formation of trays 100 of different size specifications for accommodating different numbers of battery cells.

[0050] Thus, a first accommodating cavity is formed in each of the first side plate 111 and the second side plate 121, so that both ends of the first adjusting member 21 cooperating with the first accommodating cavity are respectively disposed at one end of the first side plate 111 and the second side plate 121 adjacent to each other, facilitating the adjustment of the position between the first side plate 111 and the second side plate 121. The first side plate 111 and the second side plate 121 face each other along the length direction of the tray body 10, which can facilitate the setting of the first adjusting member 21 between the first side plate 111 and the second side plate 121 and increase the adjustment accuracy of the tray 100.

[0051] According to some embodiments of the present invention, as Figure 1 shown, at least one fixing hole is formed in the first adjusting member 21, and the fixing hole is adapted for a fastener 212 to pass through to connect the tray body 10 and the first adjusting member 21.

[0052] For example, fixing holes are formed on the side surface of the first adjusting member 21 along the width direction of the tray body 10. The fixing holes penetrate through the two side walls of the first adjusting member 21 along the width direction of the tray body 10. An installation hole is provided at a position of the second accommodating portion 12 opposite to the fixing hole. When the installation hole and the fixing hole are opposite to each other along the width direction of the tray body 10, the first adjusting member 21 can be fixed to the second accommodating portion 12 by passing a fastener 212 through the installation hole and the fixing hole, ensuring that the first accommodating portion 11 and the second accommodating portion 12 can remain in the current position after adjustment. Thus, at least one fixing hole is formed on the first adjusting member 21, which can facilitate the connection between the first adjusting member 21 and the second side plate 121 of the second accommodating portion 12, improve the connection strength and stability between the first connecting member and the second side plate 121, and prevent the end of the first adjusting member 21 adjacent to the second side plate 121 from being not tightly connected to the second side plate 121, resulting in the loosening of the internal battery cells.

[0053] According to some embodiments of the present invention, there are multiple fixing holes, and the multiple fixing holes are arranged at intervals along the length direction of the tray body 10.

[0054] That is to say, the multiple fixing holes are respectively arranged at intervals along the length direction of the tray body 10 on the multiple first adjusting members 21, and at the same time, the multiple fixing holes are respectively arranged at intervals along the height direction of the tray body 10 on the multiple first adjusting members 21. For example, one installation hole is formed on the second accommodating portion 12, and multiple fixing holes are formed on the first adjusting member 21. Since the first adjusting member 21 and the second accommodating portion 12 can move relative to each other, the installation hole can be opposite to any one of the multiple fixing holes respectively to realize the fixation of the first adjusting member 21 and the second accommodating portion 12. The number of fixing holes can be determined according to the corresponding size types of the tray 100, and each fixing hole represents a different size.

[0055] Thus, there are multiple fixing holes, and the multiple fixing holes are respectively arranged at intervals along the length direction of the tray body 10. By adjusting the position where the fastener 212 is connected to the fixing hole of the first adjusting member 21, the distance between the first side plate 111 and the second side plate 121 can be adjusted, thereby adjusting the length of the tray body 10 to meet the requirements of battery cells with different capacities and quantities. The arrangement of the multiple fixing holes can realize the multi-stage adjustment between the first accommodating portion 11 and the second accommodating portion 12 to adapt to the wider size requirements of the tray 100.

[0056] In addition, the multiple fixing holes are respectively arranged along the height direction of the tray body 10 on different first adjusting members 21. Multiple fasteners 212 can be arranged on the second side plate 121 to respectively cooperate with the fixing holes arranged on the multiple first adjusting members 21, effectively improving the connection strength between the first adjusting member 21 and the second side plate 121 and enhancing the reliability of the connection between the first adjusting member 21 and the second side plate 121.

[0057] According to some embodiments of the present utility model, as Figure 1 and Figure 3 shown, at least one second receiving cavity is respectively formed at one end of the first receiving part 11 and the second receiving part 12 adjacent to each other; the adjusting assembly 20 includes at least one second adjusting member 22, and both ends of the second adjusting member 22 are respectively fitted in the second receiving cavities opposite to each other in the first receiving part 11 and the second receiving part 12 along the length direction of the tray body 10.

[0058] That is, the second receiving cavities are respectively located at one end of the first receiving part 11 and the second receiving part 12 adjacent to each other, and the second receiving cavities on one end of the first receiving part 11 and the second receiving part 12 adjacent to each other are arranged at intervals along the length direction of the tray body 10; one end of the second adjusting member 22 is fitted with the second receiving cavity at one end of the first receiving part 11 adjacent to the second receiving part 12, and the other end of the second adjusting member 22 extends in a direction away from the first receiving part 11 along the length direction of the tray body 10 and is fitted with the second receiving part 12 adjacent to one end of the first receiving part 11. In this embodiment, one end of the second adjusting member 22 is fixedly connected to the first receiving part 11, and the other end of the second adjusting member 22 is in guiding cooperation with the second receiving part 12.

[0059] Thus, both ends of the second adjusting member 22 are respectively fitted in the second receiving cavities opposite to each other in the first receiving part 11 and the second receiving part 12 along the length direction of the tray body 10. The second receiving cavity can provide a setting space for the second adjusting member 22, save the space occupied by the tray body 10, and at the same time avoid the height of the second adjusting member 22 in the height direction of the tray body 10 from being too high, which affects the placement of the battery inside the tray 100, and provides sufficient space for the battery.

[0060] According to some embodiments of the present utility model, as Figure 3 shown, the first receiving part 11 includes a first side plate 111 and a first bottom plate 112. The first bottom plate 112 is connected to the first side plate 111, and the first side plate 111 is arranged on both sides of the first bottom plate 112 along the width direction of the tray body 10; the second receiving part 12 includes a second side plate 121 and a second bottom plate 122. The second bottom plate 122 is connected to the second side plate 121, and the second side plate 121 is arranged on both sides of the second bottom plate 122 along the width direction of the tray body 10.

[0061] That is, one end of each of the two first side plates 111 is connected to both sides of the first bottom plate 112 along the width direction of the tray body 10, and the other ends of the two first side plates 111 extend upward along the height direction of the tray body 10. One end of each of the two second side plates 121 is connected to both sides of the second bottom plate 122 along the width direction of the tray body 10, and the other ends of the two second side plates 121 extend upward along the height direction of the tray body 10. The first bottom plate 112 and the second bottom plate 122 are configured as the bottom of the tray 100 in this embodiment, and at the same time define a cooling flow channel, that is, the first bottom plate 112 and the second bottom plate 122 act as cold plates. One end of the second adjusting member 22 is fixedly connected to the first bottom plate 112, and the other end of the second adjusting member 22 is movably connected to the second bottom plate 122. A cooling flow channel is formed in the second adjusting member 22, and the cooling flow channel in the second adjusting member 22 is communicated with the cooling flow channels in the first bottom plate 112 and the second bottom plate 122.

[0062] Thus, the first side plates 111 are arranged on both sides of the first bottom plate 112 along the width direction of the tray body 10, and the second side plates 121 are arranged on both sides of the second bottom plate 122 along the width direction of the tray body 10, so that both the bottom plate and the side plates of the tray body 10 can be adjusted, facilitating the synchronous adjustment of the first accommodating portion 11 and the second accommodating portion 12.

[0063] Optionally, a sealing arrangement is made at the connection between the second adjusting member 22 and the first bottom plate 112 and the second bottom plate 122.

[0064] According to some embodiments of the present invention, as Figure 3 shown, the first bottom plate 112 and the second bottom plate 122 are opposite to each other along the length direction of the tray body 10, and the first bottom plate 112 and the second bottom plate 122 respectively form a second accommodating cavity.

[0065] That is, the first bottom plate 112 and the second bottom plate 122 respectively form a second accommodating cavity, such that both ends of the second adjusting member 22 cooperating with the second accommodating cavity are respectively arranged at one end of the first bottom plate 112 and the second bottom plate 122 adjacent to each other. Thus, the first bottom plate 112 and the second bottom plate 122 are connected by the second adjusting member 22 and can be adjusted in the length direction of the tray body 10, so that when the tray 100 needs size adjustment, the bottom plate and the side plates can be synchronously adjusted.

[0066] According to some embodiments of the present invention, as Figure 3As shown, the tray 100 further includes: side beams 30 disposed on both sides of the tray body 10 in the width direction. The side beams 30 are connected to the tray body 10. The side beams 30 include a first connecting beam 31 and a second connecting beam 32. The first connecting beam 31 is connected to the first accommodating portion 11, and the second connecting beam 32 is connected to the second accommodating portion 12. The adjusting assembly 20 includes at least one third adjusting member 23 disposed between the first connecting beam 31 and the second connecting beam 32.

[0067] That is, the first connecting beam 31 is disposed on both sides of the tray 100 in the width direction and is connected to the first side plate 111. The second connecting beam 32 is disposed on both sides of the tray 100 in the width direction and is connected to the second side plate 121. The first connecting beam 31 and the second connecting beam 32 disposed on the same side in the width direction of the tray body 10 are spaced apart along the length direction of the tray body 10. One end of the third adjusting member 23 is connected to one end of the first connecting beam 31 adjacent to the second connecting beam 32, and the other end of the third adjusting member 23 is connected to one end of the second connecting beam 32 adjacent to the first connecting beam 31. In this embodiment, one end of the third adjusting member 23 is fixedly connected to the first connecting beam 31, and the fixed connection method can be fixed connection by riveting or bolts, etc. The other end of the third adjusting member 23 is movably connected to the second connecting beam 32. For example, the other end of the third adjusting member 23 is in guiding cooperation with the second connecting beam 32, and the second connecting beam 32 can move along the length direction of the tray body 10 towards the first connecting beam 31 along the third adjusting member 23 to realize the adjustment of the position of the side beam 30.

[0068] Thus, the third adjusting member 23 is disposed between the first connecting beam 31 and the second connecting beam 32, which can realize the connection between the first connecting beam 31 and the second connecting beam 32. At the same time, by adjusting the connection length between the third adjusting member 23 and the second connecting beam 32, the distance between the first connecting beam 31 and the second connecting beam 32 can be adjusted. When the distance between the first side plate 111 and the second side plate 121 changes, the distance between the first connecting beam 31 and the second connecting beam 32 can change synchronously, effectively improving the adjustment efficiency of the tray 100 between different sizes.

[0069] According to some embodiments of the present invention, as Figure 3 shown, third accommodating cavities are respectively formed at the ends of the first connecting beam 31 and the second connecting beam 32 adjacent to each other, and both ends of the third adjusting member 23 are respectively engaged with the opposite third accommodating cavities of the first connecting beam 31 and the second connecting beam 32.

[0070] That is, the third accommodation cavity is respectively located at one end of the first connecting beam 31 and the second connecting beam 32 adjacent to each other. One end of the third adjusting member 23 is engaged with the third accommodation cavity on the end of the first connecting beam 31 adjacent to the second connecting beam 32, and the other end of the third adjusting member 23 is engaged with the third accommodation cavity on the end of the second connecting beam 32 adjacent to the first connecting beam 31. Among them, the third adjusting member 23 and the third accommodation cavity of the first connecting beam 31 are in a fixed fit, and the third adjusting member 23 and the third accommodation cavity of the second connecting beam 32 are in a movably fit.

[0071] Thus, both ends of the third adjusting member 23 are respectively engaged with the opposite third accommodation cavities of the first connecting beam 31 and the second connecting beam 32, which can provide a setting space for the third adjusting member 23 at one end adjacent to the first connecting beam 31 and the second connecting beam 32, facilitating the positioning of both ends of the third adjusting member 23 on the first connecting beam 31 and the second connecting beam 32 respectively. At the same time, it provides a guiding effect for the cooperation of the third adjusting member 23 on the first connecting beam 31 and the second connecting beam 32.

[0072] According to some embodiments of the present invention, as Figure 1 shown, the tray 100 further includes: a cover plate and a seal 40. The cover plate is connected to the tray body 10; the seal 40 is disposed between the cover plate and the first adjusting member 21.

[0073] The cover plate and the tray body 10 are arranged along the height direction of the tray body 10. One side of the tray body 10 facing the cover plate is open, and the battery cells and the like are loaded into the tray body 10 from the open side, and the cover plate realizes the sealing of the tray body 10. Since the first accommodating portion 11 and the second accommodating portion 12 are connected by the first adjusting member 21, and the first adjusting member 21 is disposed in the first accommodation cavity of the first side plate 111 and the second side plate 121, when the cover plate is connected to the tray body 10, a gap is formed between the cover plate and the first adjusting member 21, and the seal 40 is disposed at the gap to realize the sealing of the tray 100. In this embodiment, since the first accommodating portion 11 and the second accommodating portion 12 are adjustable, the portion of the seal 40 and the first adjusting member 21 located outside the first accommodation cavity are opposite and cover each other.

[0074] Thus, the seal 40 is disposed between the cover plate and the first adjusting member 21, which can ensure that the upper surface after the connection of the first adjusting member 21 and the seal 40 is on the same horizontal plane as the upper surface of the side beam 30, and at the same time improve the sealing performance of the tray 100 during use.

[0075] According to some embodiments of the present invention, the tray 100 has a stretched state in which it faces each other and a contracted state in which it faces away from each other, and at least one relative adjustment assembly 20 of the first accommodating portion 11 and the second accommodating portion 12 moves between the stretched state and the contracted state.

[0076] For example, when the required number of batteries is small, the second receiving portion 12 in the tray 100 is in a contracted state relative to the adjusting assembly 20; when the required number of batteries is large, the second receiving portion 12 in the tray 100 is in a stretched state relative to the adjusting assembly 20. Thus, the tray 100 has a stretched state in which it moves towards each other and a contracted state in which it moves away from each other. At least one of the first receiving portion 11 and the second receiving portion 12 moves between the stretched state and the contracted state relative to the adjusting assembly 20. The second receiving portion 12 can adjust its relative position with respect to the first receiving portion 11 according to the required number of battery cells, thereby adjusting the length of the tray 100, which facilitates the formation of trays 100 of different specifications.

[0077] According to some embodiments of the present invention, at least one end of the adjusting assembly 20 is riveted to the tray body 10.

[0078] That is, after the size of the tray 100 is defined according to the required number of battery cells, the relative fixing holes on the adjusting assembly 20 are moved to the required length position, and the fixing holes at at least one end of the adjusting assembly 20 are cooperated with the fastener 212, and the length of the seal 40 is adjusted, then the length adjustment of the tray 100 can be completed. In this embodiment, the fastener 212 is a rivet.

[0079] Thus, at least one end of the adjusting assembly 20 being riveted to the tray body 10 can facilitate the positioning of the adjusting assembly 20 on the tray 100, ensure the fixed length of the adjusting assembly 20. At the same time, the riveting method can avoid the occurrence of stress concentration at the connection between the adjusting assembly 20 and the tray 100, making the connection part have higher strength and stiffness, making the connection between the adjusting assembly 20 and the tray 100 more efficient and reliable, and facilitating the installation and disassembly of the adjusting assembly 20.
