[0033] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] Reference below Figure 1-Figure 7 A vehicle 100 according to an embodiment of the present invention is described.

[0035] like Figure 1-Figure 7As shown, the vehicle 100 according to the embodiment of the present invention includes: a vehicle body 10 and a first power battery 20. The vehicle 100 may be a pure electric bus, and the vehicle body 10 has a roof frame 11. It should be noted that in the height direction of the vehicle 100, the roof frame 11 may be arranged above the vehicle body 10, and the first power battery 20 is arranged above the roof frame 11. The first power battery 20 and the roof frame 11 are integrated. The first power battery 20 includes a battery bottom plate 22, a battery upper cover 23 and a plurality of battery cells 21. The plurality of battery cells 21 are sandwiched between the battery bottom plate 22 and the battery upper cover 23, and the plurality of battery cells 21 are stacked in the height direction of the vehicle 100. It should be explained that the first power battery 20 may be arranged above the roof frame 11, and the plurality of battery cells 21 may be stacked up and down in the height direction of the vehicle 100.

[0036] In the related art, the power battery pack includes a receiving device and a plurality of battery modules installed in the receiving device. The battery module is assembled from a plurality of battery cells. The receiving device generally includes a bottom plate and side beams. The side beams are arranged around the bottom plate. In order to make the receiving device have sufficient strength and facilitate the installation of the battery module, a plurality of cross beams and longitudinal beams are generally arranged between the side beams. The plurality of cross beams, longitudinal beams, side beams and bottom plate together define a plurality of receiving spaces for receiving the battery modules. Each battery module is arranged in a corresponding receiving space. However, due to the presence of the cross beams and longitudinal beams, the volume utilization rate of the receiving device is low, which is about 40%. The number of battery cells that can be installed is limited, and the endurance of the power battery pack cannot be effectively improved. In addition, during the assembly process, each battery module needs to be fixed to the cross beam, and a large number of screws and other fasteners are required to fasten the module. At the same time, the cross beam or longitudinal beam has a certain weight, which leads to an increase in the weight of the receiving device. The cross beam and longitudinal beam are arranged in the receiving device, and the structure is complex, which increases the complexity of the manufacturing process of the receiving device. The battery cells need to be assembled into battery modules and then arranged in the receiving device, and the operation steps are complicated.

[0037] In the present invention, a plurality of battery cells 21 are sandwiched between a battery bottom plate 22 and a battery upper cover 23, and the plurality of battery cells 21 are stacked in the height direction of the vehicle to form a first power battery 20, that is, the first power battery 20 is formed by the battery cells 21 in a module-free form, and the battery cells 21 are metal shell batteries, that is, the shell of the battery cells 21 is made of metal material, so the battery cells 21 themselves can be used to increase the structural strength, and there is no need to set a reinforcing structure in the accommodating device, thereby reducing the space occupied by the cross beam and / or the longitudinal beam in the accommodating device, and effectively improving the energy density, capacity, voltage and endurance of the entire power battery; and the accommodating device is only composed of the battery bottom plate 22 and the battery upper cover 23, the manufacturing process is simplified, the assembly complexity of the battery cells 21 is reduced, and the production cost is reduced. On the other hand, the increased energy density of the power battery reduces the weight of the first power battery 20, further improves the endurance of the vehicle 100, and achieves lightweighting of the vehicle 100.

[0038] At the same time, due to the high rigidity structure of the first power battery 20, by arranging the first power battery 20 on the top cover frame 11, the rigidity of the top cover frame 11 can be greatly enhanced, and the deformation of the top cover frame 11 caused by the vibration of the vehicle 100 during driving can be reduced. Moreover, the profile height of the top cover frame 11 can be reduced, thereby reducing the center of mass height of the first power battery 20, ensuring that the vehicle 100 has a larger roll angle, and can to a certain extent avoid the vehicle 100 from rolling over when turning, which can improve the driving safety of the vehicle 100; at the same time, the weight of the top cover frame 11 can be reduced, further realizing the lightweight of the vehicle 100.

[0039] In addition, the present invention can replace the battery cells 21 individually, thereby reducing the difficulty of overall disassembly of the first power battery 20 and improving the efficiency of installation and disassembly of the first power battery 20 .

[0040] Therefore, a first power battery 20 is provided, and the first power battery 20 is composed of a plurality of battery cells 21 in a module-free form, which can reduce the total weight of the first power battery 20, improve the energy density of the first power battery 20, and facilitate the replacement of a single battery cell 21 in the first power battery 20, thereby improving the installation, disassembly and replacement efficiency of the first power battery 20.

[0041] In some embodiments of the present invention, Figure 5 and Figure 6As shown, the battery bottom plate 22 can be fixedly connected to the top cover frame 11. It should be noted that in the height direction of the vehicle 100, the battery bottom plate 22 can be arranged above the top cover frame 11, and the battery bottom plate 22 can be fixedly connected to the top cover frame 11. Specifically, the top cover frame 11 can include a frame longitudinal beam 13, and the frame longitudinal beam 13 can be extended along the front and rear direction of the vehicle 100. The battery bottom plate 22 can be connected to the frame longitudinal beam 13 by bolt connection, and the battery upper cover 23 can be constructed as a non-metallic heat-insulating upper cover structure. Such an arrangement can make the battery bottom plate 22 and the top cover frame 11 form a high-strength integral structure, further increase the structural strength of the top cover frame 11, and further avoid the vibration generated during the driving of the vehicle 100 from being transmitted to the top cover frame 11 and causing the top cover frame 11 to deform.

[0042] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the battery cell 21 can be configured as a flat structure. It needs to be explained that, in the height direction of the vehicle 100, a plurality of battery cells 21 can be stacked in the first power battery 20. The battery cells 21 arranged in the first power battery 20 can be configured as a flat structure. Preferably, the battery cells 21 arranged in the first power battery 20 can be configured as long battery cells 21 with a flat structure. Then, the surface area of ​​the battery cell 21 is greater than the surface area of ​​the battery cell in the related art, thereby increasing the heat dissipation area of ​​the battery cell 21 and improving the heat dissipation rate of the battery cell 21, thereby improving the safety of the first power battery 20 and making the first power battery 20 safer and more reliable. Preferably, the battery cells 21 arranged in the first power battery 20 are configured as a rectangular structure or a square structure, so as to improve the space utilization rate of the first power battery 20 and increase the electric capacity of the first power battery 20, thereby improving the driving range of the vehicle 100.

[0043] In addition, by configuring the battery cell 21 to be a flat structure, the center of mass height of the first power battery 20 can be further reduced, thereby further reducing the center of mass height of the vehicle 100 .

[0044] In some embodiments of the present invention, Figure 5 and Figure 6As shown, the first power battery 20 may further include: a mounting frame 24 , a battery side beam 25 may be provided at the edge of the battery bottom plate 22 , the mounting frame 24 may be clamped between the battery upper cover 23 and the battery side beam 25 , and the mounting frame 24 may be connected to the top cover frame 11 . It should be noted that the battery side beam 25 can be set at the edge of the battery bottom plate 22, and the battery side beam 25 can be welded to the battery bottom plate 22. In the height direction of the vehicle 100, part of the structure of the mounting frame 24 can be clamped between the battery cover 23 and the battery side beam 25. The mounting frame 24 clamped between the battery cover 23 and the battery side beam 25 can be connected to the top cover frame 11. Specifically, the mounting frame 24 clamped between the battery cover 23 and the battery side beam 25 can be connected to the top cover frame 11 by bolts. Such a setting can integrate the first power battery 20 on the vehicle body 10, and can further increase the structural stiffness of the top cover frame 11, thereby avoiding the increase in the volume and weight of the top cover frame 11 due to insufficient structural stiffness of the top cover frame 11, and can achieve a lightweight setting of the vehicle 100.

[0045] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the mounting frame 24 may include: a first connecting plate 26, the first connecting plate 26 may be sandwiched between the battery upper cover 23 and the battery side beam 25, a portion of the structure of the first connecting plate 26 may extend out of the first power battery 20, and the portion of the structure of the first connecting plate 26 extending out of the first power battery 20 is suitable for connecting with the top cover frame 11. It should be explained that in the height direction of the vehicle 100, a portion of the structure of the first connecting plate 26 may be arranged between the battery upper cover 23 and the battery side beam 25, another portion of the structure of the first connecting plate 26 may extend out of the first power battery 20, and a portion of the structure of the first connecting plate 26 extending out of the first power battery 20 may be connected to the top cover frame 11, specifically, the first connecting plate 26 extending out of the first power battery 20 may be fixedly connected with the frame longitudinal beam 13 of the top cover frame 11 by bolt connection, so that the first power battery 20 can be conveniently arranged on the top cover frame 11.

[0046] As some embodiments of the present invention, Figure 5 and Figure 6As shown, the vehicle body 10 may further include a mounting sleeve 3, the upper surface of the mounting sleeve 3 may be arranged in contact with the lower surface of the first connecting plate 26 of the mounting frame 24, the lower portion of the mounting sleeve 3 may be embedded in the skeleton longitudinal beam 13, the mounting sleeve 3 may be provided with a through hole, the first connecting plate 26 may also be provided with a through hole corresponding to the through hole of the mounting sleeve 3, the through holes of the mounting sleeve 3 and the first connecting plate 26 may be formed by machining, the side walls of the through holes of the mounting sleeve 3 and the first connecting plate 26 may be provided with an internal thread that cooperates with the external thread of the bolt, the mounting sleeve 3 and the first connecting plate 26 may be fixedly connected together by bolts, such an arrangement may ensure the connection reliability between the first power battery 20 and the skeleton longitudinal beam 13, may avoid the first power battery 20 and the skeleton longitudinal beam 13 from falling off, and may further increase the structural rigidity of the top cover skeleton 11.

[0047] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the mounting frame 24 may further include: a second connecting plate 27 and a vertical plate 28 , the vertical plate 28 may be connected between the first connecting plate 26 and the second connecting plate 27 , and the second connecting plate 27 and the vertical plate 28 may be located inside the first power battery 20 . It should be noted that the first connecting plate 26, the second connecting plate 27 and the vertical plate 28 can together constitute the mounting frame 24, the first connecting plate 26, the second connecting plate 27 and the vertical plate 28 can be connected by welding, the first connecting plate 26, the second connecting plate 27 and the vertical plate 28 can also be an integrally formed part, one end of the vertical plate 28 can be connected to the first connecting plate 26, and the other end of the vertical plate 28 can be connected to the second connecting plate 27. Preferably, the lower end of the vertical plate 28 is connected to the first connecting plate 26, and the upper end of the vertical plate 28 is connected to the second connecting plate 27. The second connecting plate 27 and the vertical plate 28 can be arranged in the first power battery 20, and the vertical plate 28 and the second connecting plate 27 can be welded to the battery cover 23. Such an arrangement can improve the structural strength of the first power battery 20 and avoid deformation of the first power battery 20 caused by vibration generated during the driving of the vehicle 100.

[0048] In some embodiments of the present invention, Figure 5 and Figure 6As shown, the first power battery 20 may further include: a spacer 29. In the height direction of the vehicle 100, a spacer 29 may be sandwiched between at least two adjacent battery cells 21 among the multiple battery cells 21. It should be explained that the first power battery 20 may include one spacer 29, or may include multiple spacers 29. Preferably, a spacer 29 is sandwiched between any two adjacent battery cells 21. The material of the spacer 29 may be a lightweight aluminum alloy with good rigidity. Such a configuration may enable the first power battery 20 to be constructed as an integral integrated rigid battery pack, which may support the battery cells 21 to improve the mechanical structural performance of the first power battery 20, and may also isolate the battery cells 21 at each layer to a certain extent, thereby improving the safety and reliability of the first power battery 20 to a certain extent.

[0049] As an embodiment of the present invention, the spacer 29 can be connected to the second connecting plate 27 or the vertical plate 28. It should be noted that, in the height direction of the vehicle 100, part of the multiple spacers 29 can be welded to the second connecting plate 27, and another part of the multiple spacers 29 can be welded to the vertical plate 28. Such an arrangement can improve the structural strength of the first power battery 20.

[0050] Specifically, as an embodiment of the present invention, two rows of stacked cell groups can be arranged in the first power battery 20, and each cell group includes a plurality of cell groups 21 stacked in the height direction of the vehicle 100. In the height direction of the vehicle 100, three layers of long cell 21 with a flat structure can be stacked in the first power battery 20, and a partition plate 29 is sandwiched between two adjacent cell 21, that is, two partition plates 29 spaced apart in the height direction are arranged in the first power battery 20, the upper partition plate 29 can be connected to the second connecting plate 27 of the mounting frame 24, and the lower partition plate 29 can be connected to the vertical plate 28 of the mounting frame 24. Such an arrangement can realize an arrangement form of the first power battery 20.

[0051] In some embodiments of the present invention, Figure 5-Figure 7 As shown, the partition plate 29 can be constructed as a hollow plate. The hollow plate is a plate body with holes formed inside, and the shape of the holes can be circular, square, rectangular, triangular or elliptical, etc. By setting the partition plate 29 as a hollow plate, the weight of the partition plate 29 can be reduced while ensuring the rigidity, thereby reducing the weight of the first power battery 20, further improving the endurance of the vehicle, and achieving lightweighting of the vehicle.

[0052] In some embodiments of the present invention, Figure 5-Figure 7As shown, the partition plate 29 is provided with a plurality of channels 1, and the plurality of channels 1 can be arranged in parallel with each other. The channel 1 can be a through hole extending along the length direction of the vehicle 100, and the length direction of the vehicle 100 refers to the front-rear direction of the vehicle 100. The channel 1 can be formed by mechanical processing, or by extrusion molding. The channel 1 inside the partition plate 29 can be used as a cold air channel of the air cooling system of the first power battery 20, or as a channel for the heat dissipation fluid of the liquid cooling system of the first power battery 20, or as a channel for arranging cable harnesses. When the first power battery 20 is cooled by air cooling, the heat dissipation medium can be the cold air of the air conditioner on the top of the vehicle 100, which has high cooling efficiency and does not need to set up a separate air cooling system for battery heat dissipation.

[0053] It should be explained that the multiple channels 1 may be through holes extending along the length direction of the vehicle 100, the multiple channels 1 may be sequentially spaced along the width direction of the vehicle 100, and the multiple channels 1 may be mutually parallelly arranged in the partition plate 29. In this way, it is convenient to arrange the heat dissipation system of the first power battery 20, improve the cooling efficiency, ensure the temperature consistency of the battery cell 21, extend the service life of the battery cell 21, and also facilitate the arrangement of the cable harness.

[0054] In some embodiments of the present invention, Figure 5-Figure 7 As shown, the partition plate 29 can be a honeycomb plate. It can be understood that the honeycomb plate is a plate formed by two thin panels firmly bonded to both sides of a layer of honeycomb core material. By setting the core material as a hexagonal honeycomb core, these mutually restrained dense honeycombs are like many small I-beams, which can disperse the pressure from the panel, make the plate evenly stressed, and ensure the high flatness of the partition plate. The honeycomb plate also has the advantages of high strength-to-weight ratio, strong pressure resistance, good shock resistance, no deformation, and light weight. Using the honeycomb plate as the partition plate 29 can improve the structural strength of the first power battery 20, reduce the dead weight of the first power battery 20, avoid the deformation of the first power battery 20 and the top cover frame 11 due to the vibration generated during the driving of the vehicle, and facilitate the first power battery 20 and the top cover frame 11 to form a high-strength overall structure.

[0055] In some embodiments of the present invention, the plurality of battery cells 21 may form a plurality of battery cell groups, and the plurality of battery cells 21 in each battery cell group may be stacked in the height direction of the vehicle 100, and the adjacent battery cell groups may be spaced apart in the width direction of the vehicle 100. It should be noted that the plurality of battery cells 21 in the first power battery 20 may form a plurality of battery cell groups, and the plurality of battery cells 21 in each battery cell group may be stacked in the height direction of the vehicle 100, and the adjacent battery cell groups may be spaced apart in the width direction of the vehicle 100. Such a configuration may facilitate the installation and removal of the first power battery 20, improve the efficiency of the installation and removal of the first power battery 20, and save the space required to be occupied by the first power battery 20.

[0056] In some embodiments of the present invention, the vehicle 100 may further include: at least one second power battery 30 , the vehicle body 10 may further have a floor frame 12 , the floor frame 12 may be located between the front wheels and the rear wheels of the vehicle 100 , and the second power battery 30 may be disposed below the floor frame 12 . It should be noted that the number of the second power battery 30 may be one or more. A floor frame 12 may be provided between the front wheel and the rear wheel of the vehicle 100. The second power battery 30 may be provided on the floor frame 12. In the height direction of the vehicle 100, one or more second power batteries 30 may be provided below the floor frame 12. Specifically, the second power battery 30 may also be composed of a plurality of battery cells 21. In the height direction of the vehicle 100, the plurality of battery cells 21 of the second power battery 30 may be provided in a single layer or in a stacked manner. In this way, the plurality of battery cells 21 in the second power battery 30 do not need to be provided as a battery module. Compared with the prior art, more battery cells 21 may be provided in the second power battery 30, thereby improving the energy density of the second power battery 30, and further enabling the vehicle 100 to have a longer mileage. In addition, different thermal management methods may be adopted for the first power battery 20 and the second power battery 30, respectively. Such a configuration is conducive to ensuring the temperature consistency of the battery cells 21 in the first power battery 20 and the second power battery 30, thereby extending the service life of the battery cells 21.

[0057] Moreover, since the vehicle 100 does not have a power battery pack arranged in the rear area of ​​the rear suspension, the length of the rear suspension can be shortened, thereby increasing the wheelbase of the vehicle 100, increasing the space in the low-floor passenger area, increasing the space in the height direction of the rear suspension passenger area, and increasing the layout space of the powertrain of the vehicle 100.

[0058] As some embodiments of the present invention, the battery cells 21 in the second power battery 30 may also be constructed as a flat structure. It should be explained that in the height direction of the vehicle 100, a plurality of battery cells 21 may be arranged in a single layer or in stacks in the second power battery 30. The battery cells 21 arranged in the second power battery 30 may be constructed as a flat structure. Preferably, the battery cells 21 arranged in the second power battery 30 may be constructed as long battery cells 21 with a flat structure. Preferably, the battery cells 21 arranged in the second power battery 30 are arranged in a rectangular structure or a square structure. It should be noted that a single battery cell 21 of the long battery cell 21 has a high power. Such an arrangement can improve the space utilization of the second power battery 30 and can also increase the total power of the second power battery 30, thereby improving the cruising range of the vehicle 100.

[0059] It should be explained that by constructing the battery cell 21 into a flat structure, the center of mass height of the second power battery 30 can be lowered, thereby lowering the center of mass height of the vehicle 100, ensuring that the vehicle 100 has a larger roll angle, and avoiding rollover of the vehicle 100 when turning to a certain extent, thereby improving the driving safety of the vehicle 100.

[0060] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the lowest point height of the lower surface of the second power battery 30 can be higher than the height of the lower surface of the side skirt 15 of the vehicle body 100. It should be explained that after the second power battery 30 is installed on the floor frame 12, the upper plane of the second power battery 30 can be lower than the lower plane of the low floor area of ​​the vehicle 100, and the lowest point height of the lower surface of the second power battery 30 can be higher than the height of the highest point of the lower surface of the side skirt 15. This arrangement can maintain the floor height in the wheelbase area of ​​the vehicle 100, and can maintain the first step height and the height of the low floor area of ​​the vehicle 100, thereby ensuring the convenience of passengers getting on and off the vehicle, improving the riding experience of passengers, and avoiding the impact of the wheelbase length, longitudinal passing angle and ground clearance of the vehicle 100 due to the installation of the second power battery 30 on the floor frame 12, thereby avoiding the impact of the second power battery 30 on the passability of the vehicle 100 due to the installation of the second power battery 30 on the floor frame 12.

[0061] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the floor frame 12 may be formed with a plurality of battery installation areas 14, and the second power battery 30 may be multiple, and the multiple battery installation areas 14 and the multiple second power batteries 30 may be arranged in a one-to-one correspondence. It should be noted that the multiple battery installation areas 14 may be arranged on the floor frame 12, and the multiple second power batteries 30 may be respectively installed in the multiple battery installation areas 14. In this way, the number of the second power batteries 30 may be arranged according to the needs of the vehicle 100, and the installation position of the second power battery 30 may be adjusted according to the needs of the installation position, thereby improving the arrangement flexibility of the second power battery 30, and facilitating the removal of the second power battery 30 from the bottom of the vehicle 100, and improving the removal efficiency of the second power battery 30.
