[0036] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] refer to Figures 1 to 3 The embodiment of the utility model provides a vehicle (not shown), including a vehicle body (not shown), a seat (not shown), a support member 40 and a battery pack 1000 in the embodiment of the utility model. The battery pack 1000 is connected to the vehicle body, the seat is connected to the support member 40, and the support member 40 cooperates with the longitudinal beam 30 of the battery pack 1000 and slides relatively.

[0038] The specific structure of the vehicle body is not limited. The seats are arranged in the vehicle body, and the seats can be arranged as needed, for example, one row, two rows or even three rows of seats are arranged, and each row can be arranged with two or three seats side by side. Taking the four-door five-seat model as an example, the seats include front seats and rear seats, the front seats are two side by side and spaced, and the rear seats are three connected as one. The specific structure of the support member 40 is not limited, and the support member 40 is connected to the bottom of the seat, and the connection method can be an integrated type or a split type, which is not limited. The battery pack 1000 is the battery pack 1000 in any embodiment of the utility model. The longitudinal beam 30 of the battery pack 1000 not only serves as a support and fixation structure of the tray 100 and a fixed and pressed structure of the battery cell, but also serves as a support and guide structure of the support member 40, so that the support member 40 cooperates with the longitudinal beam 30 and can slide relatively, so that the seat can slide along the longitudinal beam 30, that is, the longitudinal beam 30 integrates the functions of the longitudinal beam 30 of the traditional battery pack 1000 and the seat slide rail of the vehicle.

[0039] The vehicle of the embodiment of the utility model is a vehicle with a battery pack 1000, which can be a pure electric vehicle, a plug-in hybrid electric vehicle, an extended-range hybrid electric vehicle, etc., without limitation. Among them, the vehicle body and the battery pack 1000 of the embodiment of the utility model adopt integrated integration technology, and the battery pack 1000 is no longer simply connected to the vehicle body. Specifically, the battery pack 1000 is connected to the vehicle body, and the support member 40 connected to the seat can slide along the longitudinal beam 30 of the battery pack 1000, that is, the longitudinal beam 30 of the battery pack 1000 plays the role of the seat slide rail, which improves the integration of the battery pack 1000 and the vehicle body.

[0040] Please refer to Figures 1 to 3 The embodiment of the present invention further provides a battery pack 1000, the battery pack 1000 includes the longitudinal beam 30 in any embodiment of the present invention, or the battery pack 1000 includes the longitudinal beam assembly in any embodiment of the present invention, or the battery pack 1000 includes the tray 100 in any embodiment of the present invention.

[0041] The battery pack 1000 further includes a battery cell (not shown) and a cover plate 200. The tray 100 of the battery pack 1000 has a receiving space 101, in which the battery cell is received, and the cover plate 200 is connected to the side of the frame 20 of the tray 100 that is away from the bottom plate 10. The cover plate 200 is formed with an installation seam 201, which corresponds to the slide groove 31 of the longitudinal beam 30.

[0042] The specific structure of the battery cell is not limited. Optionally, the battery cell is a soft-pack battery cell, which is fixed by the tray 100. Compared with the solution of first loading the battery cell into the shell and then installing it on the tray 100, the battery cell is a soft-pack battery cell and is directly fixed to the tray 100, which saves the step of loading the battery cell into the shell, eliminates the shell, and improves space utilization.

[0043] The tray 100 is the tray 100 in the embodiment of the present invention, and is not limited here. The cover plate 200 is connected to the frame 20 of the tray 100 and closes the receiving space 101, so that the battery cell is in an environment isolated from the outside world, ensuring the safety of the battery cell.

[0044] The cover plate 200 can be a whole piece with a mounting seam 201 formed thereon, or a plurality of cover plates 200 can be arranged in sequence at intervals, with the gap between two adjacent pieces forming the mounting seam 201, without limitation. The mounting seam 201 corresponds to the slide groove 31 of the longitudinal beam 30, that is, the support member 40 can pass through the mounting seam 201 and cooperate with the slide groove 31 of the longitudinal beam 30, so as to avoid interference between the cover plate 200 and the support member 40.

[0045] Optional, reference Figures 1 to 3 The cover plate 200 is connected to the longitudinal beam 30, and the battery pack 1000 further includes a seal, which is disposed between the cover plate 200 and the longitudinal beam 30. The seal may be a rubber pad, a sealant, or the like, and is not limited thereto.

[0046] Optionally, the longitudinal beam 30 includes a top surface 34, the top surface 34 faces the seat, the seal is disposed on the top surface 34, and the cover plate 200 is disposed on the surface of the seal facing away from the longitudinal beam 30. In other words, the cover plate 200 is indirectly connected to the longitudinal beam 30, that is, the cover plate 200 is connected to the longitudinal beam 30 through the seal.

[0047] Optionally, the cover plate 200 may be directly connected to the top surface 34 of the longitudinal beam 30 , and the sealing member is connected to the side surface of the longitudinal beam 30 and the surface of the cover plate 200 facing the longitudinal beam 30 to close the joint between the cover plate 200 and the longitudinal beam 30 .

[0048] By providing the sealing member, the receiving space 101 cannot be connected to the outside through the gap between the longitudinal beam 30 and the cover plate 200, thereby ensuring that the battery cell is in a closed environment and meeting the sealing requirements for its normal operation.

[0049] In addition, the seal may have a certain elastic deformation capability, and may absorb a certain impact to protect the battery pack 1000 .

[0050] Optional, reference Figure 1 The battery pack 1000 may further include a fastener 300, which may be a rivet, a screw or the like. The fastener 300 connects and fixes the cover plate 200 to the longitudinal beam 30, thereby making the connection and fixation between the cover plate 200 and the longitudinal beam 30 more stable and reliable. The fastener 300 may be disposed at an edge of the cover plate 200 close to the mounting seam 201, and there may be a plurality of fasteners 300 disposed at intervals along the first direction X.

[0051] refer to Figures 1 to 3The embodiment of the utility model further provides a tray 100, comprising a bottom plate 10 and a frame 20. The frame 20 is connected to the bottom plate 10, and together with the bottom plate 10, forms a receiving space 101.

[0052] The frame 20 may include a first side beam 21 and a second side beam 22 that are arranged opposite to each other, and a third side beam 23 and a fourth side beam 24 that are arranged opposite to each other. The first side beam 21 and the second side beam 22 both extend along the first direction X and are arranged at intervals in the second direction Y. The third side beam 23 and the fourth side beam 24 both extend along the second direction Y and are arranged at intervals in the first direction X. One end of the first side beam 21 is connected to one end of the third side beam 23, the other end of the first side beam 21 is connected to one end of the fourth side beam 24, one end of the second side beam 22 is connected to the other end of the third side beam 23, and the other end of the second side beam 22 is connected to the other end of the fourth side beam 24. The first direction X intersects with the second direction Y and may be perpendicular to each other. For example, the first direction X is the length direction of the tray 100, and the second direction Y is the width direction of the tray 100. After the battery pack 1000 is installed on the vehicle body, the first direction X may be the same as the front-to-rear direction of the vehicle (the length direction of the vehicle), and the second direction Y may be the same as the left-right direction of the vehicle (the width direction of the vehicle). In this way, the frame 20 forms a ring structure connected end to end. The frame 20 is arranged on one side surface of the bottom plate 10, so that the bottom plate 10 and the frame 20 enclose a receiving space 101, and the receiving space 101 is open. After the battery pack 1000 is installed, the cover plate 200 is connected to the side of the frame 20 facing away from the bottom plate 10, and the cover plate 200 and the bottom plate 10 are opposite in the thickness direction of the battery pack 1000 (i.e., the third direction Z, the third direction Z intersects with the first direction X and the second direction Y in pairs, and can be further perpendicular to each other), so that the cover plate 200 closes the receiving space 101.

[0053] Optional, reference Figures 1 to 3 The pallet 100 of one embodiment of the utility model further includes the longitudinal beam 30 in any embodiment of the utility model, and the longitudinal beam 30 is accommodated in the accommodation space 101. In this embodiment, the longitudinal beam 30 and the supporting member 40 are independently provided, and the longitudinal beam 30 and the supporting member 40 are two parts, which are transported and installed as two materials. When the longitudinal beam 30 is installed, the longitudinal beam 30 is first placed in the accommodation space 101 and then connected. Specifically, the two ends of the longitudinal beam 30 can be connected to the third side beam 23 and the fourth side beam 24, and can be connected to the bottom plate 10. After the longitudinal beam 30 is installed, the supporting member 40 is installed.

[0054] Optional, reference Figures 1 to 3The pallet 100 of another embodiment of the utility model further includes the longitudinal beam assembly of any embodiment of the utility model, and the longitudinal beam assembly is accommodated in the accommodation space 101. In this embodiment, the longitudinal beam 30 and the supporting member 40 are one component, and are transported and installed as one material. With reference to the installation method of the longitudinal beam 30 described above, after the longitudinal beam 30 is installed, since the supporting member 40 is already one component with the longitudinal beam 30, there is no need to install the supporting member 40 again.

[0055] Optional, reference Figure 1 and Figure 2 There are multiple longitudinal beams 30 and they are arranged at intervals along the second direction Y. One of the seats of the vehicle corresponds to at least two longitudinal beams 30. The second direction Y intersects with the first direction X.

[0056] The number of longitudinal beams 30 can be 2, 3, 4, etc., without limitation. Among the multiple longitudinal beams 30, one longitudinal beam 30 can be arranged closely to the first side beam 21, and one longitudinal beam 30 can be arranged closely to the second side beam 22. The remaining longitudinal beams 30 are all located between the first side beam 21 and the second side beam 22. The multiple longitudinal beams 30 can be arranged at equal or unequal intervals in the second direction Y without limitation. When the longitudinal beam 30 is arranged closely to the first side beam 21 and / or the second side beam 22, it can reinforce the first side beam 21 and / or the second side beam 22 and enhance its structural strength. The other longitudinal beams 30 arranged between the first side beam 21 and the second side beam 22 and having a gap with the first side beam 21 and the second side beam 22 can enhance the overall structural strength of the tray 100, and can divide the receiving space 101 of the tray 100 into multiple subspaces, each of which can be provided with a battery cell to enhance the fixing effect on the battery cell.

[0057] The seat of the vehicle corresponds to at least two longitudinal beams 30, for example, one seat corresponds to two longitudinal beams 30, so that one seat is connected to two support members 40, and the two support members 40 slide relative to the two longitudinal beams 30 in a one-to-one correspondence, so as to enhance the support stability of the seat. Of course, the seat can correspond to three or even more longitudinal beams 30 to further enhance the support stability thereof.

[0058] When the vehicle has two front seats, the two front seats are arranged at intervals along the left-right direction of the vehicle, and each front seat corresponds to at least two longitudinal beams 30. When the vehicle has three rear seats, the three rear seats are arranged at intervals along the left-right direction of the vehicle, and two of the three rear seats can share the same longitudinal beam 30 with the two front seats.

[0059] Alternatively, there may be one longitudinal beam 30, which is disposed in the middle between the first side beam 21 and the second side beam 22, and the longitudinal beam 30 may be equidistant from the first side beam 21 and the second side beam 22. One longitudinal beam 30 may also function as a seat rail, which will not be described in detail.

[0060] The pallet 100 may further include structures such as a crossbeam 50 and a lifting lug 60. The crossbeam 50 is received in the receiving space 101 and is disposed between the third side beam 23 and the fourth side beam 24 and extends along the second direction Y. The crossbeam 50 may be provided with a groove in which the longitudinal beam 30 is received. The lifting lug 60 may be connected to the outer side of the side beam (i.e., the side surface away from the receiving space 101), and may be specifically connected to the first side beam 21 and the second side beam 22. Regarding other structures of the pallet 100, there is no limitation in the embodiments of the utility model.

[0061] refer to Figures 1 to 3 The embodiment of the utility model further provides a longitudinal beam 30 of a battery pack 1000 , the longitudinal beam 30 extends along a first direction X, and the longitudinal beam 30 is provided with a slide groove 31 extending along the first direction X. The slide groove 31 is suitable for cooperating with a support member 40 connected to a seat of a vehicle, so that the support member 40 slides along the slide groove 31 .

[0062] The slide groove 31 can be provided at any position of the longitudinal beam 30 , and the specific shape of the slide groove 31 is not limited, as long as the support member 40 can slide in the slide groove 31 along the first direction X, and the longitudinal beam 30 can support the support member 40 .

[0063] In the embodiment of the utility model, the longitudinal beam 30 of the battery pack 1000 is improved, so as to enhance the integration degree between the battery pack 1000 and the vehicle body.

[0064] Specifically, the longitudinal beam 30 provided in the embodiment of the utility model has a slide groove 31 provided on the longitudinal beam 30, and the slide groove 31 is used to cooperate with the support member 40, and the support member 40 is used to connect with the seat of the vehicle, so that the seat can slide in the slide groove 31 of the longitudinal beam 30 through the support member 40. The longitudinal beam 30 plays the role of a seat slide rail, and the longitudinal beam 30 itself serves as a component of the tray 100 of the battery pack 1000, which plays the role of strengthening the structural stability and fixing the battery cells, thereby improving the integration of the battery pack 1000 and the vehicle body.

[0065] In addition, since the longitudinal beam 30 is provided with a slide groove 31 and the support member 40 extends into the slide groove 31 to slide, compared with the method of directly installing the slide rail on the cover plate 200 of the battery pack 1000, the solution of this embodiment can reduce the space occupied in the height direction of the vehicle and improve the utilization rate of the space inside the vehicle.

[0066] Optional, reference Figure 3The longitudinal beam 30 includes a first surface 32 and a top surface 34 . The first surface 32 is suitable for facing the battery cells of the battery pack 1000 , and the top surface 34 is suitable for facing the seat. The slide groove 31 is connected to the outside from the top surface 34 .

[0067] The longitudinal beam 30 further includes a second surface 33, which is disposed opposite to the first surface 32, and a top surface 34 connects the first surface 32 and the second surface 33. In combination with the aforementioned embodiment in which the receiving space 101 of the tray 100 may have multiple longitudinal beams 30, for the longitudinal beam 30 that is in close contact with the first side beam 21 or the second side beam 22, the second surface 33 of the longitudinal beam 30 is in close contact with the first side beam 21 or the second side beam 22, and the first surface 32 is used to be in close contact with the battery cell, that is, the first surface 32 faces the battery cell, and the second surface 33 faces away from the battery cell. For the longitudinal beam 30 that is not in close contact with the first side beam 21 and the second side beam 22, the first surface 32 and the second surface 33 both face the battery cell. It should be understood that the battery cells that the first surface 32 and the second surface 33 face are the battery cells contained in different subspaces separated by the longitudinal beam 30, rather than the battery cells in the same subspace. For the embodiment with only one longitudinal beam 30 , since the longitudinal beam 30 is spaced apart from the first side beam 21 and the second surface 33 , the first surface 32 and the second surface 33 of the longitudinal beam 30 both face the battery cells.

[0068] The slide groove 31 is connected to the outside from the top surface 34, that is, the slide groove 31 is opened from the top surface 34. In this way, after the support member 40 cooperates with the slide groove 31, the support member 40 extends out of the longitudinal beam 30 from the top surface 34, which can avoid interference between the support member 40 and structures such as the battery cell and the cover plate 200.

[0069] Optional, reference Figure 3 The longitudinal beam 30 may also be provided with a weight-reducing groove 35, which may be located at any position of the longitudinal beam 30 and extend along the first direction X. On the basis of ensuring the structural strength of the longitudinal beam 30, the weight of the longitudinal beam 30 may be reduced, thereby reducing the weight of the battery pack 1000 and the vehicle. Optionally, the weight-reducing groove 35 is located on the side of the slide groove 31 facing the bottom plate 10 of the tray 100, and is separated from the external space (e.g., the receiving space 101 of the tray 100) in the second direction Y.

[0070] In one embodiment, reference Figure 3 The slide groove 31 includes a card slot 311 and a connecting slot 312. The card slot 311 is located inside the longitudinal beam. The connecting slot 312 is connected to the card slot 311, and the connecting slot 312 runs through the top surface. In the second direction Y, the size of the card slot 311 is larger than the size of the connecting slot 312, and the second direction Y intersects with the first direction X.

[0071] Optionally, the cross-sectional shape of the sliding groove 31 is in a "mountain" shape. The cross-sectional shape of the sliding groove 31 refers to the shape enclosed by the inner wall surface of the sliding groove 31. The "mountain" shape is a general shape, and the shape formed by appropriate deformation of local details should also be considered as the "mountain" shape. The shape of the support member 40 is adapted to the cross-sectional shape of the sliding groove 31 being in a "mountain" shape. For example, the cross-sectional shape of the part of the support member 40 that cooperates with the sliding groove 31 can be approximately in a "mountain" shape, so that the inner wall of the sliding groove 31 is substantially in a close contact state with the support structure, and the inner wall of the sliding groove 31 can play a role in supporting, limiting, and guiding the support structure. In addition, after the "mountain"-shaped sliding groove 31 cooperates with the support member 40, the support member 40 cannot be detached from the sliding groove 31 in the third direction Z (i.e., the thickness direction of the battery pack 1000, the height direction of the vehicle), which can avoid the problem of the seat being pulled off from the longitudinal beam 30.

[0072] Optionally, the cross-sectional shape of the sliding groove 31 can also be any other feasible shape, such as a "convex" shape, an "inverted T" shape, an "L" shape, an "inverted F" shape, etc., which will not be elaborated here. Correspondingly, the cross-sectional shape of the part of the support member 40 that cooperates with the sliding groove 31 can also be the corresponding shape above.

[0073] Optionally, referring to Figures 1 to 3 , the sliding groove 31 is adapted to correspond to the front row seat or the rear row seat of the vehicle. In this embodiment, the length of the longitudinal beam 30 (i.e., the dimension along the first direction X) can be shorter and approximately correspond to the area occupied by the front row seat or the rear row seat, or the length of the longitudinal beam 30 can be longer and can approximately correspond to the area occupied by the front row seat area and the area occupied by the rear row seat at the same time. For the embodiment with a longer longitudinal beam 30, the sliding groove 31 is only opened in a partial area of the longitudinal beam 30 to correspond to the front row seat or the rear row seat of the vehicle, and the sliding groove 31 may not be opened in other areas, as long as the part where the sliding groove 31 is opened can be used as the slide rail for the seat to slide.

[0074] Another option, referring to Figures 1 to 3 , the sliding groove 31 is adapted to correspond to the front row seat and the rear row seat of the vehicle at the same time. In this embodiment, the length of the longitudinal beam 30 corresponds to the area occupied by the front row seat area and the area occupied by the rear row seat.
