As power battery applications continue to expand, market demand is also growing.

[0045] Please refer to Figure 1 , Figure 1 Schematic diagram of the exploded structure of a battery 100 (power battery) provided in some embodiments of the present application. The battery 100 includes a housing 101 and a battery cell 102, and the battery cell 102 is accommodated in the housing 101. The housing 101 includes a first housing 101a and a second housing 101b. The first housing 101a and the second housing 101b cover each other, and the first housing 101a and the second housing 101b jointly define a storage space for accommodating the battery cell 102. The second housing 101b can be a hollow structure with one end open, and the first housing 101a can be a plate-like structure. The first housing 101a covers the open side of the second housing 101b, so that the first housing 101a and the second housing 101b jointly define a storage space; the first housing 101a and the second housing 101b can also be hollow structures with one side open, and the open side of the first housing 101a covers the open side of the second housing 101b. Of course, the box body 101 formed by the first box body 101a and the second box body 101b can be in various shapes, such as a cylinder or a rectangular parallelepiped.

[0046] There may be one or more battery cells 102 in the housing 101. Multiple battery cells 102 may be connected in series, in parallel, or in a hybrid connection. A hybrid connection refers to multiple battery cells 102 being connected both in series and in parallel. Multiple battery cells 102 may be directly connected in series, in parallel, or in a hybrid connection, and then the entirety formed by the multiple battery cells 102 may be housed in the housing 101. Of course, the battery 100 may also be in the form of a battery module in which multiple battery cells 102 are first connected in series, in parallel, or in a hybrid connection, and then the multiple battery modules are further connected in series, in parallel, or in a hybrid connection to form an entirety, which is then housed in the housing 101. The battery 100 may also include other structures. For example, the battery may further include a busbar component for achieving electrical connection between the multiple battery cells 102.

[0047] The battery cell 102 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 102 can be cylindrical, flat, rectangular, or in other shapes.

[0048] In some embodiments of the present application, the battery 100 can serve not only as an operating power source for the vehicle 200 , but also as a driving power source for the vehicle 200 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 200 .

[0049] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a vehicle 200 provided in some embodiments of the present application. The vehicle 200 can be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle.

[0050] The vehicle 200 is provided with a battery 100 inside. The battery 100 may be provided at the bottom, head, or tail of the vehicle 200. The battery 100 may be used to power the vehicle 200. For example, the battery 100 may serve as an operating power source for the vehicle 200.

[0051] The vehicle 200 may further include an axle 201, wheels 202 connected to the axle 201, a motor 203, and a controller 204. The motor 203 is used to drive the axle 201 to rotate, the controller 204 is used to control the operation of the motor 203, and the battery 100 can be used to provide power for the operation of the motor 203 and other components in the vehicle.

[0052] In some related embodiments, a vehicle includes a body assembly, including a seat cross member, a floor, and a battery. Because the seat cross member, floor, and battery are arranged vertically to form a lower body structure, the lower body structure occupies a large vertical space and is inconvenient to maintain.

[0053] Based on this, an embodiment of the present application provides a vehicle body assembly and a vehicle, which are used to alleviate the problem that the lower vehicle body occupies a large space and is inconvenient to maintain.

[0054] In the embodiment of the present application, the up and down direction refers to the direction from the roof to the wheels, the front and rear direction refers to the direction from the vehicle's cab to the trunk, and the left and right direction refers to the layout direction of the two wheels located in the front or rear row of the vehicle.

[0055] refer to Figures 3 to 6 In some embodiments, the vehicle body assembly includes an upper vehicle body 1 , an energy cabin 2 , and a seat cross member 3 .

[0056] The energy cabin 2 includes a top plate 21, a cover plate 22 and a battery cell 102. A cavity is formed between the top plate 21 and the cover plate 22, and the battery cell 102 is arranged in the cavity; the energy cabin 2 is arranged below the upper body 1, and the top plate 21 serves as the floor of the body assembly.

[0057] The seat cross beam 3 is detachably connected to the upper vehicle body 1 and the top plate 21 .

[0058] In some related technologies, the seat crossbeam is integrated with the battery. This means that during after-sales repairs, the seat crossbeam must be removed at the same time as the battery. This compromises the rigidity of the upper body, making it impossible to reinstall the battery after the repair. Furthermore, battery removal requires the simultaneous removal of the seat crossbeam, which in turn necessitates the removal of interior components such as the seat carpet, significantly increasing labor hours.

[0059] In response to the various problems existing in the aforementioned related technologies, in the embodiments of the present application, the top plate 21 of the energy cabin 2 serves as the floor of the vehicle body assembly, eliminating the need for a separate floor and reducing the space occupied by the lower vehicle body in the vertical direction. Furthermore, the seat crossbar 3 is detachably connected to the upper vehicle body 1 and the top plate 21. When the energy cabin 2 needs to be disassembled for maintenance, the energy cabin 2 can be directly removed without removing the seat crossbar 3. Consequently, there is no need to remove interior components such as seats and carpets, making maintenance easier. Furthermore, the seat crossbar 3 remains on the upper vehicle body 1, so replacing the energy cabin 2 does not affect the structural strength of the upper vehicle body 1, preventing deformation of the upper vehicle body 1 and simplifying the repositioning of the energy cabin 2.

[0060] In an embodiment of the present application, the seat crossbeam 3 is detachably connected to the upper body 1 and the top plate 21, respectively. The seat crossbeam 3 can be removed from the upper body 1 and removed together with the energy cabin 2, or the seat crossbeam 3 can be separated from the energy cabin 2, and the seat crossbeam 3 remains on the upper body 1. The seat crossbeam 3 can be adjusted at will according to needs.

[0061] In the embodiment of the present application, at least one battery cell 102 may be provided in the energy compartment 2. Optionally, the energy compartment 2 is a battery 100.

[0064] In the above embodiment, the connecting frame 4 is detachably connected to the upper body 1, and the connecting frame 4 is detachably connected to the seat cross beam 3. The connection between the connecting frame 4 and the upper body 1 can be removed separately, so that the connecting frame 4 is separated from the upper body 1 along with the seat cross beam 3. Alternatively, the connection between the connecting frame 4 and the seat cross beam 3 can be removed separately, so that the connecting frame 4 remains on the upper body 1, which is convenient for disassembly. Moreover, the connecting frame 4 remains on the upper body 1 or the seat cross beam 3, which can reduce the amount of operation during the resetting of the seat cross beam 3.

The first plate 41 and the second plate 42 are located in different planes.

[0067] In the above embodiment, the first plate 41 and the second plate 42 are located in different planes and can be connected to the upper body 1 and the seat cross member 3, respectively, located in different planes, enabling flexible adjustment of angle and position. Furthermore, the third plate 43 connecting the first and second plates 41, 42 increases the rigidity of the connection and improves the overall stability of the structure. Adjusting the size of the third plate 43 can adjust the distance between the first and second plates 41, 42, making it suitable for installation locations of varying thicknesses.

[0068] In some embodiments, after the connecting frame 4 is connected to the vehicle body 1 and the seat cross beam 3 , the first plate 41 is higher than the second plate 42 .

[0076] In some embodiments, the connecting member 6 includes a bolt, a screw, a shaft, a pin, etc.

[0077] In some embodiments, the seat cross beam 3 includes a first cross beam 31, a second cross beam 32, a first connecting beam 33 and a second connecting beam 34.

The connection part between the connecting frame 4 and the upper body 1 is different from the connection part between the connecting frame 4 and the seat cross beam 3. The connection between the connecting frame 4 and the upper body 1 can be removed separately, so that the connecting frame 4 is separated from the upper body 1 along with the seat cross beam 3, or the connection between the connecting frame 4 and the seat cross beam 3 can be removed separately, so that the connecting frame 4 remains on the upper body 1, which is convenient for disassembly, and the connecting frame 4 remains on the upper body 1 or the seat cross beam 3, which can reduce the amount of operation during the resetting of the seat cross beam 3.
