[0059] Currently, market trends show that the application scope of battery cells is expanding rapidly. Besides playing a crucial role in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, battery cells are also widely used in various electric vehicles such as electric bicycles, electric motorcycles, and electric cars. Furthermore, they are widely used in high-tech fields such as military equipment and aerospace. With the continuous expansion of battery cell applications, market demand is also continuously increasing.
[0060] The core component of an electric vehicle is the battery pack, which is typically integrated into the energy compartment. The energy compartment is mounted at or near the bottom of the electric vehicle's body structure to provide adequate protection for the battery pack. Therefore, electric vehicles require a higher strength and rigidity body structure to support the weight of the battery and ensure the overall strength and crash safety of the entire passenger compartment.
[0061] In related technologies, the upper body structure is usually closely connected to the lower body structure through the partitions on the two A-pillars. However, this connection method only enhances the local strength of the body structure to a certain extent and cannot improve the overall strength of the passenger compartment. Especially when facing conditions such as small offset, getting stuck, or head-on collision, it is easy to cause deformation or damage to the passenger compartment, thus posing a serious threat to the occupants.
[0062] Based on the above considerations, in order to solve the problem of insufficient structural strength of the vehicle passenger compartment to a certain extent, this application provides a vehicle body structure and a vehicle. The vehicle body structure includes an upper body structure and a lower body structure. The upper body structure includes two A-pillars and a first crossbeam. The first crossbeam extends along the width direction of the vehicle body structure and connects the two A-pillars. The lower body structure includes a front bulkhead. The top of the front bulkhead is provided with a connecting surface. The first crossbeam is provided on the connecting surface and connected to the front bulkhead.
[0063] In the technical solution of this application embodiment, the upper body structure and the lower body structure can be connected by the connection between the front bulkhead and the first crossbeam. The first crossbeam extends along the width direction of the body structure and connects the two A-pillars, thereby improving the structural strength of the entire passenger compartment to a certain extent.
[0064] In this application, the battery cell may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the embodiments of this application are not limited to these. The battery cell may be cylindrical, flat, cuboid, or other shapes, etc., and the embodiments of this application are not limited to these. Battery cells are generally divided into three types according to their packaging method: cylindrical battery cells, cuboid / square battery cells, and pouch battery cells, and the embodiments of this application are not limited to these.
[0065] The battery apparatus mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or mixed connections via a busbar.
[0066] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.
[0067] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.
[0068] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cells housed within the housing.
[0069] As an example, the battery cell assembly can be a battery module, which can be housed in a housing by fixing the battery module in the housing.
[0070] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.
[0071] As an example, the housing may include a first part and a second part. The first part and the second part are fastened together to form a closed receiving space inside the housing to house the battery cell assembly. Here, "closed" refers to covering or closing, which can be either sealed or unsealed. The first part may be an upper cover, and the second part may be a lower housing.
[0072] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating a closed storage space inside the enclosure to house the individual battery cells.
[0073] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.
[0074] For ease of explanation, the following embodiments will be described using a vehicle 1000 as an example of an electrical device according to an embodiment of this application.
[0075] Please refer to Figure 1 , Figure 1This is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The vehicle 1000 is equipped with a battery device 300, which can be located at the bottom, front, or rear of the vehicle 1000. The battery device 300 can be used to power the vehicle 1000; for example, the battery device 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during starting, navigation, and driving.
[0076] In some embodiments of this application, the battery device 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.
[0077] Please refer to Figure 2 , Figure 2 This is an exploded structural diagram of a battery device 100 according to some embodiments of this application. The battery device 100 includes a housing 20 and a battery cell 10, with the battery cell 10 housed within the housing 20. The housing 20 provides a space for accommodating the battery cell 10, and the housing 20 can adopt various structures. In some embodiments, the housing 20 may include a first portion 21 and a second portion 22, which overlap each other, jointly defining a space for accommodating the battery cell 10. The second portion 22 may be a hollow structure with one open end, and the first portion 21 may be a plate-like structure, covering the open side of the second portion 22 so that the first portion 21 and the second portion 22 jointly define the space; alternatively, the first portion 21 and the second portion 22 may both be hollow structures with one open side, with the open side of the first portion 21 covering the open side of the second portion 22. Of course, the housing 20 formed by the first portion 21 and the second portion 22 can be of various shapes, such as a cylinder, a cuboid, etc.
[0078] In the battery device 100, there can be multiple battery cells 10, which can be connected in series, parallel, or in a mixed manner. A mixed connection means that multiple battery cells 10 are connected in both series and parallel configurations. Multiple battery cells 10 can be directly connected in series, parallel, or in a mixed manner, and then the entire assembly of the multiple battery cells 10 is housed within the housing 20. Alternatively, the battery device 100 can also consist of multiple battery cells 10 first connected in series, parallel, or in a mixed manner to form battery modules, and then these battery modules are connected in series, parallel, or in a mixed manner to form a whole, which is also housed within the housing 20. The battery device 100 may also include other structures; for example, it may include a busbar component for electrical connection between the multiple battery cells 10.
[0079] Firstly, please refer to Figures 3 to 4 This application provides a vehicle body structure 500, which includes an upper vehicle body structure 52 and a lower vehicle body structure 58. The upper vehicle body structure 52 includes two A-pillars 521 and a first crossbeam 523. The first crossbeam 523 extends along the width direction of the vehicle body structure 500 and connects the two A-pillars 521. The lower vehicle body structure 58 includes a front bulkhead 581. The top of the front bulkhead 581 is provided with a connecting surface 581a. The first crossbeam 523 is disposed on the connecting surface 581a and connected to the front bulkhead 581.
[0080] Specifically, please combine Figure 3 The lower body structure 58 includes a front compartment assembly 587 and an energy compartment 585. A front bulkhead 581 is located between the front compartment assembly 587 and the energy compartment 585. The energy compartment 585 is used to house the battery device 100. The upper body structure 52 is fixedly connected to the lower body structure 58 to form the frame of the passenger compartment of the vehicle 1000. The length direction of the body structure 500 is from the front to the rear of the vehicle, or from the rear to the front of the vehicle. The width direction of the body structure 500 is perpendicular to the length direction of the body structure 500, such as the left-right direction of the vehicle 1000. Figure 3 In the figure, the length direction of the body structure 500 is the front-to-back direction, the width direction of the body structure 500 is the left-to-right direction, and the height direction of the body structure 500 is the up-to-down direction.
[0081] In this embodiment, the upper body structure 52 includes two A-pillars 521 and a first crossbeam 523. The A-pillars 521 connect the roof and windshield of the vehicle 1000. The first crossbeam 523 extends in the left-right direction and connects to the two A-pillars 521 on the left and right sides. The top of the front bulkhead 581 of the lower body structure 58 has a connecting surface 581a, which extends in the left-right direction. The first crossbeam 523 is disposed on the connecting surface 581a and connected to the front bulkhead 581, so that the upper body structure 52 and the lower body structure 58 are tightly connected.
[0082] When the first crossbeam 523 is tightly connected to the connection surface 581a, the first crossbeam 523 and the front panel 581 together form a transverse support structure, providing additional support force in the vertical (up and down) direction of the vehicle body structure 500. At the same time, it also provides a certain degree of stability in the front and rear directions of the vehicle body structure 500, preventing excessive deformation of the vehicle body structure 500 when subjected to impacts in the vertical and front and rear directions. Moreover, as a transverse member connecting the left and right A-pillars 521, the first crossbeam 523 can, to a certain extent, enhance the strength and rigidity of the vehicle body structure 500 in the transverse (left and right) direction.
[0083] Optionally, please refer to Figure 7 , in one embodiment, the A-pillar 521 can adopt a "square" shaped rolled steel tubular beam structure, that is, the cavity cross-section of the tubular beam structure is a closed cross-section of a "square" shape, and the cavity extends along the length direction of the A-pillar 521, which can enable the tubular beam structure to better transfer and disperse stress when bearing bending moment, and to a certain extent, improve the overall strength of the A-pillar 521.
[0084] Optionally, please refer to Figure 8 , in one embodiment, the A-pillar 521 can adopt a "day" shaped extruded aluminum tubular beam structure, that is, the cavity cross-section of the tubular beam structure is a closed cross-section of a "day" shape, and the cavity extends along the length direction of the A-pillar 521, which can enable the tubular beam structure to better transfer and disperse stress when bearing bending moment, and to a certain extent, improve the overall strength of the A-pillar 521.
[0085] Thus, the upper vehicle body structure 52 and the lower vehicle body structure 58 can be connected through the connection between the front panel 581 and the first crossbeam 523. The first crossbeam 523 extends along the width direction of the vehicle body structure 500 and connects the two A-pillars 521, thereby improving the structural strength of the entire passenger compartment to a certain extent, making the vehicle 1000 more stable and safe during driving.
[0086] According to some embodiments of the present application, optionally, the front panel 581 and the first crossbeam 523 are connected to form a plurality of first connection points 581b, and the plurality of first connection points 581b are arranged along the width direction of the vehicle body structure 500.
[0087] Specifically, please refer to Figure 3 , the first crossbeam 523 is disposed on the connection surface 581a of the front panel 581 and connected to the front panel 581. A plurality of first connection points 581b are formed on the connection surface 581a, and the plurality of first connection points 581b are arranged along the width direction of the vehicle body structure 500, that is, the plurality of first connection points 581b are arranged along the left and right direction of the connection surface 581a, so that the connection between the front panel 581 and the first crossbeam 523 forms a stable transverse support and connection structure, making the vehicle body structure 500 have a uniform rigidity and strength distribution in the width direction.
[0088] The number of first connection points 581b can be specifically limited according to actual circumstances, and this application does not make a specific limitation in this regard. In one example, please refer to... Figure 3 The number of 581b at the first connection point is 6.
[0089] It is understandable that the connection surface 581a is the decoupling surface of the body structure 500, that is, the upper body structure 52 can be connected and separated from the lower body structure 58 on this decoupling surface.
[0090] This allows the vehicle body structure 500 to have a uniform distribution of rigidity and strength in the width direction.
[0091] According to some embodiments of this application, optionally, the first connection 581b may be formed by at least one of bolting or welding.
[0092] Alternatively, in one embodiment, the first connection 581b may be formed by bolts. (Please refer to...) Figure 3 Bolts are inserted through the first crossbeam 523 and the front bulkhead 581 in the vertical direction. They are tightly fitted with nuts to fix the first crossbeam 523 and the front bulkhead 581. This can further enhance the connection strength between the first crossbeam 523 and the front bulkhead 581, thereby fixing the upper body structure 52 and the lower body structure 58 together.
[0093] Optionally, in one embodiment, the first connection 581b can be formed by welding. The first crossbeam 523 and the front bulkhead 581 can be connected by welding. During the welding process, solder is heated above its melting point and then coated or applied to the connection surface 581a. The molten solder wets the connection surface 581a and forms a strong solder joint after cooling and solidification, so that the first crossbeam 523 and the front bulkhead 581 are fixedly connected and the first connection 581b is formed, which can further enhance the connection strength between the first crossbeam 523 and the front bulkhead 581, thereby fixing the upper body structure 52 and the lower body structure 58 together.
[0094] Optionally, in one embodiment, the first connection 581b may be formed by combining bolting and welding methods, which can further improve the stability and reliability of the first connection 581b. For example, one or more of the first connections 581b may be formed by bolting, and one or more of the first connections 581b may be formed by welding. Alternatively, a first connection 581b may be first connected by bolting and then connected by welding.
[0095] This can further enhance the connection strength between the first crossbeam 523 and the front bulkhead 581.
[0096] According to some embodiments of this application, optionally, the upper body structure 52 includes two hinge pillars 525, each hinge pillar 525 is connected to a corresponding A-pillar 521 and one end of the first crossbeam 523, and the lower body structure 58 includes a torque box 583 connected to the front bulkhead 581, with the hinge pillars 525 connected to the torque box 583.
[0097] Specifically, please combine Figure 3 and Figure 4 Two hinge pillars 525 are respectively connected to one of the corresponding A-pillars 521 and one end of the first crossbeam 523, which improves the impact resistance of the body structure 500 to a certain extent. The lower body structure 58 includes two torsion boxes 583, which are respectively connected to the left and right ends of the front bulkhead 581. These are box-shaped structures used to withstand torsional loading (torsional loading, a load that causes an object to rotate or twist about its axis). The two hinge pillars 525 are respectively connected to the torsion boxes 583 on the left and right sides, so that the upper body structure 52 and the lower body structure 58 are fixedly connected. When the vehicle 1000 is involved in a frontal collision, the torsion boxes 583 can absorb and disperse the impact energy, reducing the impact on the passenger compartment. At the same time, the connection between the hinge pillars 525 and the torsion boxes 583 can make the body structure 500 relatively stable during a collision, reducing the risk of deformation of the body structure 500 to a certain extent.
[0098] This allows the vehicle body structure 500 to remain relatively stable during a collision, reducing the risk of deformation of the vehicle body structure 500 to some extent.
[0099] According to some embodiments of this application, optionally, the hinge post 525 and the torque box 583 are connected to form a plurality of second connection points 583a, and the plurality of second connection points 583a are arranged along the length direction of the hinge post 525.
[0100] Specifically, please combine Figure 3 The hinge column 525 is located at the rear end of the torque box 583 and is connected to the torque box 583. Multiple second connection points 583a are formed between the hinge column 525 and the torque box 583. The multiple second connection points 583a are arranged along the length direction of the hinge column 525, so that the connection between the hinge column 525 and the torque box 583 forms a stable support structure with uniform rigidity and strength distribution.
[0101] The number of second connection points 583a can be specifically limited according to actual circumstances, and this application does not make a specific limitation in this regard. In one example, please refer to... Figure 3 There are 6 second connection points 583a, that is, there are 3 second connection points 583a on each side.
[0102] This ensures the overall strength of the connection between the hinge post 525 and the torque box 583.
[0103] According to some embodiments of this application, optionally, the second connection 583a may be formed by at least one of bolting or welding.
[0104] Alternatively, in one embodiment, the second connection 583a may be formed by bolts. (Please refer to...) Figure 3 Bolts pass through the hinge column 525 and the torque box 583, and are tightly fitted with nuts to fix the hinge column 525 and the torque box 583. This can further enhance the connection strength between the hinge column 525 and the torque box 583, thereby fixing the upper body structure 52 and the lower body structure 58 together.
[0105] Optionally, in one embodiment, the second connection 583a can be formed by welding. The hinge post 525 and the torque box 583 can be connected by welding. During the welding process, solder is heated above its melting point and then applied to the torque box 583. The molten solder wets the surface of the torque box 583, forming a strong solder joint after cooling and solidification. This fixes the hinge post 525 and the torque box 583 together, forming the second connection 583a, which further enhances the connection strength between the hinge post 525 and the torque box 583, thereby fixing the upper body structure 52 and the lower body structure 58 together.
[0106] Optionally, in one embodiment, the second connection 583a may be formed by combining bolting and welding methods, which can further improve the stability and reliability of the second connection 583a. For example, one or more second connections 583a may be formed by bolting, and one or more second connections 583a may be formed by welding. Alternatively, a second connection 583a may be first connected by bolting and then connected by welding.
[0107] This can further enhance the connection strength between the hinge post 525 and the torque box 583.
[0108] According to some embodiments of this application, optionally, the upper body structure 52 includes a first die-cast part 54, and the first crossbeam 523, A-pillar 521 and hinge column 525 are connected through the first die-cast part 54.
[0109] Specifically, the left and right ends of the first crossbeam 523 are respectively connected to a first die-cast part 54. Please refer to... Figure 4 and Figure 5 The first die-cast part 54 is provided with a first fixing part 54c. The first fixing part 54c and the first crossbeam 523 can be fixedly connected by means including but not limited to bolts, rivets, welding, etc., so that the first crossbeam 523 and the first die-cast part 54 are fixedly connected.
[0110] One of the first die-cast part 54 and the A-pillar 521 is provided with a first locking part 521a, and the other is provided with a first locking groove 54a. The first locking part 521a and the first locking groove 54a are tightly fitted together to fix the A-pillar 521 to the first die-cast part 54. In the embodiments of this application, please refer to... Figure 5 One end of the A-pillar 521 is provided with a first locking part 521a, and one end of the first die-cast part 54 is provided with a first locking groove 54a. The first locking part 521a can be inserted into the first locking groove 54a and tightly connected with the first locking groove 54a. At the same time, the bolt passes through the first locking part 521a and the first locking groove 54a to fix the first locking part 521a and the first die-cast part 54, thereby fixing the A-pillar 521 and the first die-cast part 54.
[0111] It is understood that in other embodiments, one end of the first die-cast part 54 is provided with a first locking part 521a, and one end of the A-pillar 521 is provided with a first locking groove 54a. The first locking part 521a can be inserted into the first locking groove 54a and tightly connected with the first locking groove 54a. At the same time, the bolt passes through the first locking part 521a and the first locking groove 54a to fix the first locking part 521a to the A-pillar 521, thereby fixing the A-pillar 521 to the first die-cast part 54.
[0112] One of the first die-cast part 54 and the hinge post 525 is provided with a second locking part 54b, and the other is provided with a second locking groove 525a. The second locking part 54b and the second locking groove 525a are tightly engaged to fix the hinge post 525 to the first die-cast part 54. In the embodiments of this application, please refer to... Figure 5 The first die-cast part 54 has a second locking part 54b at the end away from the A-pillar 521, and the hinge column 525 has a second locking groove 525a at one end. The second locking part 54b can be inserted into the second locking groove 525a and tightly connected with the second locking groove 525a. At the same time, the bolt passes through the second locking part 54b and the second locking groove 525a to fix the second locking part 54b and the second locking groove 525a, thereby fixing the hinge column 525 to the first die-cast part 54.
[0113] It is understood that in other embodiments, one end of the hinge post 525 is provided with a second locking part 54b, and one end of the first die-cast part 54 is provided with a second locking groove 525a. The second locking part 54b can be inserted into the second locking groove 525a and tightly connected to the second locking groove 525a. At the same time, the bolt passes through the second locking part 54b and the second locking groove 525a to fix the second locking part 54b to the second locking groove 525a, thereby fixing the hinge post 525 to the first die-cast part 54.
[0114] Optionally, the first die casting is a low-pressure casting, and the first die casting 54 is integrally die-cast.
[0115] Therefore, the first die-cast part 54 can improve the connection strength between the first crossbeam 523, the A-pillar 521 and the hinge pillar 525, and the resulting connection structure can reduce the deformation and vibration of the vehicle body structure 500, thereby enhancing the safety performance of the vehicle 1000 to a certain extent.
[0116] According to some embodiments of this application, optionally, the upper body structure 52 includes two sill beams 527, each sill beam 527 being connected to a corresponding hinge column 525 at one end away from the A-pillar 521, and the lower body structure 58 includes an energy compartment 585, with the sill beams 527 being connected to the energy compartment 585.
[0117] Specifically, please combine Figure 3 and Figure 4 Two door sill beams 527 are each connected to the end of a corresponding hinge pillar 525 furthest from the A-pillar 521, which enhances the lateral rigidity and safety of the body structure 500 to a certain extent. The door sill beams 527 extend in the front-rear direction, and the two door sill beams 527 are respectively connected to the left and right sides of the top of the energy compartment 585, so that the upper body structure 52 and the lower body structure 58 are fixedly connected. Therefore, the door sill beams 527 can transmit the collision force from the side, further disperse and absorb the collision energy, thereby reducing the impact on the energy compartment 585 to a certain extent.
[0118] Therefore, the impact force received by the A-pillar 521 and the first crossbeam 523 during a collision can be transmitted to the sill beam 527 through the hinge pillar 525, thereby dispersing and absorbing the collision energy and improving the strength and durability of the body structure 500 to a certain extent.
[0119] According to some embodiments of this application, optionally, the sill beam 527 and the energy compartment 585 are connected to form a plurality of third connection points 585b, and the plurality of third connection points 585b are arranged along the length direction of the sill beam 527.
[0120] Specifically, please combine Figure 3 The energy compartment 585 has connecting portions 585a on both the left and right sides, extending in the front-rear direction. A sill beam 527 is located above and connected to the connecting portions 585a, creating multiple third connection points 585b between the sill beam 527 and the connecting portions 585a. These third connection points 585b are arranged along the length of the sill beam 527, extending in the front-rear direction of the connecting portion 585a. This allows the connection between the sill beam 527 and the connecting portion 585a to form a stable lateral support structure, resulting in a uniform distribution of rigidity and strength in the length direction of the vehicle body structure 500.
[0121] The number of third connection points 585b can be specifically limited according to actual circumstances, and this application does not make a specific limitation in this regard. In one example, please refer to... Figure 3 There are 6 third connection points 585b, that is, there are 3 third connection points 585b on each of the left and right sides.
[0122] This results in a uniform distribution of rigidity and strength in the body structure 500 along its length.
[0123] According to some embodiments of this application, optionally, the third connection 585b may be formed by at least one of bolting or welding.
[0124] Alternatively, in one embodiment, the third connection 585b may be formed by bolts. (Please refer to...) Figure 3 Bolts pass through the connecting part 585a of the sill beam 527 and the energy compartment 585 in the vertical direction. They are tightly fitted with nuts to fix the sill beam 527 and the connecting part 585a together. This can further enhance the connection strength between the sill beam 527 and the energy compartment 585, thereby fixing the upper body structure 52 and the lower body structure 58 together.
[0125] Optionally, in one embodiment, the third connection 585b can be formed by welding. The sill beam 527 and the connection portion 585a can be connected by welding. During the welding process, solder is heated above its melting point and then coated or applied to the surface of the connection portion 585a. The molten solder wets the surface of the connection portion 585a, forming a strong solder joint after cooling and solidification, thus fixing the sill beam 527 and the connection portion 585a together to form the third connection 585b. This can further enhance the connection strength between the sill beam 527 and the energy compartment 585, thereby fixing the upper body structure 52 and the lower body structure 58 together.
[0126] Optionally, in one embodiment, the third connection 585b may be formed by combining bolting and welding methods, which can further improve the stability and reliability of the third connection 585b. For example, one or more third connections 585b may be formed by bolting, and one or more third connections 585b may be formed by welding. Alternatively, a third connection 585b may be first connected by bolting and then connected by welding.
[0127] This can further enhance the connection strength between the sill beam 527 and the energy compartment 585.
[0128] According to some embodiments of this application, optionally, the sill beam 527 and the hinge post 525 are integrally formed structures.
[0129] Specifically, please combine Figure 4, the sill beam 527 and the hinge column 525 adopt an integrally formed structure, that is, the sill beam 527 and the hinge column 525 are completed through an integrally formed process during manufacturing. The integrally formed process includes, but is not limited to, processes such as rolling, extrusion, and injection molding. During this process, there are no additional welding, bonding, or assembly steps, so that there are no seams or weld points between the sill beam 527 and the hinge column 525, which improves the connection strength between the sill beam 527 and the hinge column 525 to a certain extent, and thus improves the integrity and rigidity of the vehicle body structure 500 to a certain extent.
[0130] Optionally, in one embodiment, please refer to Figure 7 , the integrally formed structure of the sill beam 527 and the hinge column 525 can adopt a "square" - shaped rolled steel tube beam structure of the A - pillar structure, that is, the cavity cross - section of the tube beam structure is a closed "square" - shaped cross - section, and the cavity extends along the length direction of the sill beam 527 and the hinge column 525, which can enable the tube beam structure to better transfer and disperse stress when bearing bending moment, and improve the overall strength of the sill beam 527 and the hinge column 525 to a certain extent.
[0131] Optionally, in one embodiment, please refer to Figure 8 , the integrally formed structure of the sill beam 527 and the hinge column 525 can adopt a "day" - shaped extruded aluminum tube beam structure, that is, the cavity cross - section of the tube beam structure is a closed "day" - shaped cross - section, and the cavity extends along the length direction of the integrally formed structure of the sill beam 527 and the hinge column 525, which can enable the tube beam structure to better transfer and disperse stress when bearing bending moment, and improve the overall strength of the integrally formed structure of the sill beam 527 and the hinge column 525 to a certain extent.
[0132] Thus, the integrally formed structure can reduce the installation components, and at the same time can improve the integrity and rigidity of the vehicle body structure 500 to a certain extent.
[0133] According to some embodiments of the present application, optionally, the upper vehicle body structure 52 includes a second cross - beam 529. The second cross - beam 529 connects two A - pillars 521, and the first cross - beam 523 is spaced from the second cross - beam 529.
[0134] Specifically, please refer to Figure 3 and Figure 4, the second crossbeam 529 is located below the roof of the vehicle 1000 and is used to support and carry the weight of the roof, which increases the body rigidity and stability to a certain extent. The second crossbeam 529 extends in the left-right direction and is located above the first crossbeam 523. The first crossbeam 523 and the second crossbeam 529 are arranged at intervals. The left and right ends of the second crossbeam 529 are respectively connected to the A-pillars 521 on the left and right sides, and the left and right ends of the first crossbeam 523 are also connected to the A-pillars 521 on the left and right sides. Thus, the second crossbeam 529 can be connected to the first crossbeam 523 through the two A-pillars 521, forming a strong body frame. Therefore, in the event of a collision, the impact force can be effectively absorbed and dispersed, thereby protecting the safety of the vehicle occupants.
[0135] Optionally, please refer to Figure 8 , in one embodiment, the first crossbeam 523 and the second crossbeam 529 can adopt a "day" - shaped extruded aluminum tube beam structure, that is, the cavity cross - section of the tube beam structure is a closed cross - section of the "day" shape, and the cavity extends along the length directions of the first crossbeam 523 and the second crossbeam 529, which can enable the tube beam structure to better transfer and disperse stress when bearing bending moment, and improve the overall strength of the first crossbeam 523 and the second crossbeam 529 to a certain extent.
[0136] Optionally, please refer to Figure 7 , in one embodiment, the first crossbeam 523 and the second crossbeam 529 can adopt a "square" - shaped roll - formed steel tube beam structure, that is, the cavity cross - section of the tube beam structure is a closed cross - section of the "square" shape, and the cavity extends along the length directions of the first crossbeam 523 and the second crossbeam 529, which can enable the tube beam structure to better transfer and disperse stress when bearing bending moment, and improve the overall strength of the first crossbeam 523 and the second crossbeam 529 to a certain extent.
[0137] Thus, the first crossbeam 523 and the second crossbeam 529 can provide a strong body frame and excellent safety performance for the vehicle 1000, and improve the overall performance of the vehicle 1000 to a certain extent.
[0138] According to some embodiments of the present application, optionally, the upper body structure 52 includes a second die - casting 56, and the second crossbeam 529 is connected to the A - pillar 521 through the second die - casting 56.
[0139] Specifically, please refer to Figure 3 and Figure 4 , the two ends of the second crossbeam 529 are respectively connected to the A - pillars 521 on the left and right sides through the second die - casting 56. Optionally, in one embodiment, one of the second die - casting 56 and the second crossbeam 529 is provided with a third engaging part 56a, and the other is provided with a third engaging groove 529a. The tight fit between the third engaging part 56a and the third engaging groove 529a makes the second crossbeam 529 and the second die - casting 56 fixedly connected.
[0140] In the embodiments of this application, please refer to Figure 6 The second die-cast part 56 is provided with a third locking part 56a, and one end of the second crossbeam 529 is provided with a third locking groove 529a. The third locking part 56a can be inserted into the third locking groove 529a and tightly connected with the third locking groove 529a. At the same time, bolts pass through the third locking part 56a and the third locking groove 529a to fix the third locking part 56a to the second crossbeam 529, thereby fixing the second crossbeam 529 to the second die-cast part 56.
[0141] It is understood that in other embodiments, one end of the second crossbeam 529 is provided with a third locking part 56a, and the second die-cast part 56 is provided with a third locking groove 529a. The third locking part 56a can be inserted into the third locking groove 529a and tightly connected with the third locking groove 529a. At the same time, bolts pass through the third locking part 56a and the third locking groove 529a to fix the third locking part 56a to the second die-cast part 56, thereby fixing the second crossbeam 529 to the second die-cast part 56.
[0142] Please combine Figure 6 The second die-cast part 56 is also provided with a second fixing part 56b, which extends along the length direction of the A-pillar 521. The second fixing part 56b and the A-pillar 521 can be fixedly connected by means including but not limited to bolts, rivets, welding, etc., so that the second die-cast part 56 and the A-pillar 521 are fixedly connected.
[0143] Optionally, the second die casting 56 is a low-pressure casting, and the second die casting 56 is integrally die-cast.
[0144] Therefore, the second die-cast part 56 can improve the connection strength between the second crossbeam 529 and the A-pillar 521. The resulting connection structure can effectively absorb and disperse the impact force, and to a certain extent enhance the overall rigidity of the body structure 500, thereby improving the safety performance of the vehicle 1000 to a certain extent.
[0145] Secondly, please combine Figure 1 This application provides a vehicle 1000, which includes the body structure 500 described in any of the above embodiments.
[0146] Specifically, the upper body structure 52 and the lower body structure 58 form the basic frame of the vehicle 1000, providing support for the vehicle 1000. The vehicle 1000 includes a battery device 100, which is installed below or inside the energy compartment 585 of the lower body structure 58 to provide electrical energy to the vehicle 1000.
[0147] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
