[0062] The following describes in detail embodiments of the present application, 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 intended to be used to explain the present application, and should not be construed as limiting the present application.

[0063] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.

[0064] The following describes a cockpit frame 100 according to an embodiment of the first aspect of the present application with reference to FIG1 to FIG16 .

[0065] As shown in FIG. 1 , FIG. 6 and FIG. 14 , the cockpit frame 100 according to the embodiment of the first aspect of the present application includes: a front panel 50 and a roof outer panel 20 .

[0066] Specifically, the dash panel 50 is an integrally formed structure, the roof outer panel 20 is an integrally formed structure, and the roof outer panel 20 is connected to the dash panel 50 , wherein at least part of the dash panel 50 is located on the lower side of the roof outer panel 20 in the height direction of the vehicle 1000 .

[0067] During the production process of the front panel 50 and the top cover outer panel 20, setting the front panel 50 and the top cover outer panel 20 as an integrally molded structure can make the production efficiency of the front panel 50 and the top cover outer panel 20 higher. At the same time, the number of molds required for the production of the front panel 50 and the top cover outer panel 20 can be reduced. Therefore, the production cost of the front panel 50 and the top cover outer panel 20 can be reduced, thereby reducing the production cost of the vehicle 1000.

[0068] It is understandable that when the vehicle 1000 is heavier, the power system needs a greater driving force to drive the vehicle 1000, thereby reducing the cruising range of the vehicle 1000.

[0069] During assembly of vehicle 1000, forming the dash panel 50 and roof outer panel 20 as an integral structure eliminates the parts and steps required to join the dash panel 50 and roof outer panel 20, thereby reducing the weight of vehicle 1000, improving the range of vehicle 1000, and lowering the production cost of vehicle 1000. The roof outer panel 20 is connected to the dash panel 50, with the dash panel 50 at least partially positioned below the roof outer panel 20. This eliminates the parts required to connect the dash panel 50 and roof outer panel 20, further reducing the weight of vehicle 1000, improving the range of vehicle 1000, and lowering the production cost of vehicle 1000.

[0070] According to the cockpit frame 100 of the first aspect embodiment of the present application, by setting the front panel 50 and the top cover outer panel 20 as an integrally formed structure, connecting the top cover outer panel 20 to the front panel 50 and the front panel 50 at least partially located on the lower side of the top cover outer panel 20, the weight of the vehicle 1000 can be reduced, the endurance of the vehicle 1000 can be improved and the production cost of the vehicle 1000 can be reduced.

[0071] In some embodiments of the present application, the cockpit frame 100 further includes: two side panel assemblies 10 and a top cover outer panel 20 .

[0072] Specifically, two side panel assemblies 10 extend front to back and are spaced apart from each other left to right. A roof outer panel 20 is positioned above and connected to the two side panel assemblies 10. The side panel assemblies 10 include a side panel inner panel 11 and a side panel outer panel 12. The side panel outer panel 12 is positioned on the side of the side panel inner panel 11 that is away from the passenger compartment in the left-right direction of the vehicle 1000. The side panel assemblies 10 provide shielding for the vehicle interior from the side of the vehicle body. The double-layer structure of the side panel assemblies 10 enhances their strength. Both the side panel inner panel 11 and the side panel outer panel 12 provide sound insulation, thereby improving the quietness of the vehicle 1000.

[0073] At least one of the side panel inner 11 and the side panel outer 12 is integrally molded. That is, the side panel inner 11 or the side panel outer 12 can be integrally molded, or both can be integrally molded. In this embodiment, the side panel inner 11 and the side panel outer 12 are integrally molded. This improves production efficiency during the production of the side panel inner 11 and the side panel outer 12, reduces the number of molds used in their production, and eliminates the parts and operating steps required for assembling the side panel inner 11 and the side panel outer 12, thereby further reducing the weight of the vehicle 1000, improving the vehicle's 1000 range, and reducing the production cost of the vehicle 1000.

[0074] In some embodiments of the present application, as shown in Figures 1, 6, and 16, the cockpit frame 100 further includes a rear panel 60 connected to the side panel assembly 10 and the roof outer panel 20, wherein the rear panel 60 is an integrally formed structure. The rear panel 60 can provide a shield for the interior space at the rear of the vehicle body. By making the rear panel 60 an integrally formed structure, the production efficiency of the rear panel 60 can be improved, the number of molds used in the production of the rear panel 60 can be reduced, and the parts and operating procedures required for assembling the rear panel 60 can be eliminated, thereby further reducing the weight of the vehicle 1000, improving the range of the vehicle 1000, and reducing the production cost of the vehicle 1000.

[0075] In some embodiments of the present application, as shown in FIG. 1 , FIG. 6 and FIG. 7 , the roof outer panel 20 includes a roof body 21 and two roof longitudinal beams 22 .

[0076] The roof longitudinal beams 22 extend front and rear along the vehicle 1000 , and the two roof longitudinal beams 22 are respectively connected to the left and right sides of the roof body 21 , and the roof body 21 is connected to the side panel assembly 10 through the roof longitudinal beams 22 .

[0077] The stress is more concentrated at the connection between the side panel assembly 10 and the top cover outer panel 20, and the strength requirement of the connection between the top cover outer panel 20 and the side panel assembly 10 is also higher. The top cover longitudinal beam 22 is connected to the side panel assembly 10. During the production process, the strength of the top cover longitudinal beam 22 can be separately enhanced to meet the connection requirements without increasing the strength of the entire top cover outer panel 20, thereby reducing production costs.

[0078] The roof longitudinal beam 22 is formed integrally with the roof main body 21 , thereby further improving production efficiency and reducing production costs.

[0079] Furthermore, the roof rail 22 is adapted to be sealedly connected to the vehicle door.

[0080] As can be understood in this field, after the vehicle 1000 is assembled, the exposed surfaces of the vehicle 1000 when the doors are closed are in contact with the external environment for a long time and are easily corroded by the external environment. During the manufacturing process of the vehicle 1000, the exposed surfaces of the vehicle 1000 when the doors are closed need to be processed, thereby increasing the manufacturing cost of the vehicle 1000.

[0081] In this embodiment, the roof longitudinal beam 22 is adapted to be sealedly connected to the vehicle door, that is, the upper end of the side panel assembly 10 is arranged on the lower side of the roof longitudinal beam 22. In this way, after assembly is completed, the vehicle door and body covering parts as well as the roof longitudinal beam 22 can cover the side panel outer panel 12, so that there is no exposed part of the side panel outer panel 12. As a result, the processing process of the roof outer panel 20 can be simplified when the vehicle 1000 is manufactured, thereby reducing the production cost of the vehicle 1000.

[0082] In addition, after the vehicle 1000 is assembled, the side panel assembly 10 is connected to the top cover longitudinal beam 22 at the lower side of the top cover longitudinal beam 22. When the force on the top cover outer panel 20 is transmitted to the side panel assembly 10, the side panel assembly 10 provides support to the top cover longitudinal beam 22 upward. In this way, the connection between the top cover outer panel 20 and the side panel assembly 10 is not easily crushed to cause the connection to fail, thereby improving the reliability of the connection between the side panel assembly 10 and the top cover outer panel 20. Moreover, when the force on the top cover outer panel 20 is large and causes the connection between the side panel assembly 10 and the top cover longitudinal beam 22 to fail, the side panel assembly 10 still provides support for the top cover longitudinal beam 22, thereby improving the safety of the vehicle 1000.

[0083] Furthermore, as shown in Figures 1 and 6, the roof longitudinal beam 22 is connected to the front panel 50. It should be noted that the roof longitudinal beam 22 extends forward beyond the front edge of the roof main body 21. The portion of the roof longitudinal beam 22 that extends forward beyond the front edge of the roof main body 2121 is the roof frame front section 221. During assembly, the front panel 50 is connected to the roof frame front section 221. In this way, the front panel 50 can provide support for the roof outer panel 20 through the roof longitudinal beam 22. At the same time, the roof frame front section 221 and the front panel 50 can define an area for mounting the front windshield.

[0084] Or the roof longitudinal beam 22 is connected to the windshield lower cross beam 51 on the front panel 50. Thus, the windshield lower cross beam 51 and the roof longitudinal beam 22 can provide support for the front windshield, thereby realizing the installation of the front windshield.

[0085] In some embodiments of the present application, the roof longitudinal beam 22 is bonded to the side outer panel 12. The bonding operation is simple and can achieve a sealed connection, thereby improving production efficiency and achieving a sealed connection between the roof longitudinal beam 22 and the side outer panel 12.

[0086] In some embodiments of the present application, as shown in Figures 6 and 15 , the dash panel 50 is provided with dash flanges 52 on both sides in the left-right direction of the vehicle 1000. The dash panel 50 is connected to the side panel assembly 10 via the dash flanges 52. In the width direction of the vehicle 1000, the dash flanges 52 are provided on the side of the side panel assembly 10 facing the passenger compartment. The provision of the dash flanges 52 increases the contact area between the dash panel 50 and the side panel assembly 10, thereby improving the reliability of the connection between the dash panel 50 and the side panel assembly 10. Thus, when the vehicle 1000 is impacted from the side, the connection between the dash panel 50 and the side panel assembly 10 is less likely to crack, thereby improving the impact resistance and safety of the vehicle 1000.

[0087] Furthermore, the dash flange 52 is formed by bending backward at both ends of the dash panel 50 in the left-right direction of the vehicle 1000. To provide more space in the passenger compartment, the dash panel 50 is designed with an arc-shaped portion protruding forward in the middle. By bending the dash flange 52 backward, the angle between the dash flange 52 and the main body of the dash panel 50 becomes obtuse. This reduces the concentration of applied force on the dash flange 52, thereby improving the strength of the dash panel 50 and making it easier to form during production, thereby reducing manufacturing complexity.

[0088] In some embodiments of the present application, as shown in FIG2 , a side edge of the roof rail 22, facing away from the roof body 21, extends in the left-right direction of the vehicle 1000 to the outer surface of the side panel 12 facing away from the side panel inner panel 11, and is fixedly connected to the outer surface of the side panel outer panel 12. Thus, at the connection between the roof rail 22 and the side panel assembly 10, the roof rail 22 can wrap around the side panel outer panel 12 and the side panel inner panel 11, thereby improving the sealing reliability of the connection between the roof rail 22 and the side panel assembly 10. Furthermore, the roof rail 22 can mate with the door and body panels on the outer surface of the side panel outer panel 12, thereby facilitating the assembly of the door and body panels onto the cabin frame 100 and simplifying the mating relationship between the door and body panels and the cabin frame 100, thereby reducing assembly difficulty and improving assembly accuracy.

[0089] In some embodiments of the present application, as shown in Figures 2 and 3 , a first inner panel flange 111 is formed at the upper end of the side panel inner panel 11. The first inner panel flange 111 extends in the left-right direction toward the passenger compartment and is connected to the roof outer panel 20. The provision of the first inner panel flange 111 increases the contact area between the side panel inner panel 11 and the roof outer panel 20, thereby improving the reliability of the connection between the side panel inner panel 11 and the roof outer panel 20 and the stability of the connection between the side panel inner panel 11 and the side panel outer panel 12.

[0090] In some embodiments of the present application, the first inner panel flange 111 is bonded to the top cover outer panel 20. The bonding operation is simple and can achieve a sealed connection, thereby improving production efficiency and achieving a sealed connection between the first inner panel flange 111 and the top cover outer panel 20.

[0091] In some embodiments of the present application, as shown in Figures 1 and 2, the top cover longitudinal beam 22 includes a top frame front section 221, which extends forward beyond the front end edge of the top cover body 21, and the top frame front section 221 is formed with a first top frame flange 2211, which is formed on the side of the top frame front section 221 facing the inside of the vehicle body in the left and right directions, wherein the first top frame flange 2211 is connected to the upper surface of the first inner panel flange 111, and the first top frame flange 2211 cooperates with the first inner panel flange 111 to define a windshield mounting portion 22111 for mounting a front windshield.

[0092] Therefore, after the front windshield is installed, the first top frame flange 2211 and the first inner panel flange 111 can provide support for the front windshield on the left and right sides of the front windshield. By setting the first top frame flange 2211, the first top frame flange 2211 can increase the contact area with the front windshield, thereby improving the reliability of the front windshield installation and the sealing performance between the front windshield and the windshield mounting part 22111, and the first top frame flange 2211 can increase the contact area between the top frame front section 221 and the first inner panel flange 111, thereby improving the reliability of the connection between the top frame front section 221 and the side inner panel 11 and the stability of the top frame front section 221 on the side inner panel 11.

[0093] In some embodiments of the present application, the first top frame flange 2211 is bonded to the first inner panel flange 111. The bonding operation is simple and can achieve a sealed connection, thereby improving production efficiency and achieving a sealed connection between the first top frame flange 2211 and the first inner panel flange 111.

[0094] In some embodiments of the present application, as shown in Figures 2-4, the upper end of the side panel inner panel 11 cooperates with the roof longitudinal beam 22 to enclose a first cavity 222 extending forward and backward. The cabin frame 100 further includes a roof frame reinforcement beam 30 disposed within the first cavity 222. The provision of the roof frame reinforcement beam 30 strengthens the connection between the side panel inner panel 11 and the roof longitudinal beam 22. When the vehicle 1000 is impacted, the roof frame reinforcement beam 30 reduces deformation at the connection between the side panel inner panel 11 and the roof longitudinal beam 22, thereby reducing the probability of excessive deformation or even crushing of the cabin frame 100, thereby improving the safety of the vehicle 1000.

[0095] In some embodiments of the present application, the roof frame reinforcement beam 30 extends from the front end of the roof longitudinal beam 22 to the rear end of the roof longitudinal beam 22. In this way, the coverage area of ​​the roof reinforcement beam is larger, thereby further enhancing the strength of the connection between the side inner panel 11 and the roof longitudinal beam 22, thereby further improving the installability of the vehicle 1000.

[0096] In some embodiments of the present application, as shown in Figures 2 to 4, the upper end of the top cover outer panel 20 is located on the outside of the top frame reinforcement beam 30, that is, the top cover outer panel 20 exceeds the top frame reinforcement beam 30 in the left and right directions. In this way, the first cavity 222 can have a larger layout space, thereby facilitating the arrangement of the top frame reinforcement beam 30 in the first cavity 222.

[0097] In some embodiments of the present application, the roof frame reinforcement beam 30 and the side panel inner panel 11 are connected via fasteners and / or adhesive bonding. That is, the roof frame reinforcement beam 30 and the side panel inner panel 11 may be connected via fasteners, adhesive bonding, or both. In this embodiment, the roof frame reinforcement beam 30 and the side panel inner panel 11 are connected via fasteners and adhesive bonding. Adhesive bonding is convenient, while fastener bonding offers high reliability. During assembly, the roof frame reinforcement beam 30 is first bonded to the side panel inner panel 11, then fastened to the side panel inner panel 11, and then the roof cover outer panel 20 is placed over the roof frame reinforcement beam 30, thereby completing assembly of the roof frame reinforcement beam 30. This improves production efficiency and enhances the reliability of the connection between the roof frame reinforcement beam 30 and the side panel inner panel 11.

[0098] In some embodiments of the present application, the cabin frame 100 further includes: at least one roof cross beam 40, for example, there may be one, two, or three roof cross beams 40, the roof cross beams 40 extending left and right, connected to the roof outer panel 20, and disposed on the underside of the roof outer panel 20. By providing the roof cross beams 40, the roof cross beams 40 can provide support for the roof outer panel 20, thereby improving the structural stability of the cabin frame 100.

[0099] In some embodiments of the present application, as shown in Figures 4 and 8 , a cross-beam connection portion 112 is provided at the upper end of the side inner panel 11. The cross-beam connection portion 112 is integrally formed with the side inner panel 11 and extends in the left-right direction toward the passenger compartment. The ends of the roof crossbeam 40 are respectively connected to the cross-beam connections 112 of the two side inner panels 11. This allows for the placement of the roof crossbeam 40 on the cabin frame 100. During product design, the position and number of the cross-beam connections 112 can be adjusted to meet various product design requirements and reduce product design complexity. In particular, by integrally forming the cross-beam connection portion 112 with the side inner panel 11, the reliability of the connection between the cross-beam connection portion 112 and the side inner panel 11 can be improved, thereby improving the reliability of the roof crossbeam 40 when installed on the vehicle 1000.

[0100] In some embodiments of the present application, in the left-right direction, the distance between the outer edge of the roof outer panel 20 and the end of the cross-beam connecting portion 112 facing inwardly of the vehicle body is 50 mm to 200 mm. For example, the distance between the outer edge of the roof outer panel 20 and the end of the cross-beam connecting portion 112 facing inwardly of the vehicle body can be 50 mm, 70 mm, 100 mm, 150 mm, or 200 mm. In this way, the direct contact area between the cross-beam connecting portion 112 and the roof cross-beam 40 can be sufficiently large, thereby ensuring the reliability of the installation of the roof cross-beam 40 on the cross-beam connecting portion 112. At the same time, the extension distance of the cross-beam connecting portion 112 will not be too long, thereby ensuring that the strength of the connection between the cross-beam connecting portion 112 and the side inner panel 11 meets the support requirements of the roof cross-beam 40.

[0101] In some embodiments of the present application, one of the multiple roof crossbeams 40 is a front crossbeam 41, and the front edge of the roof body 21 extends forward beyond the front edge of the front crossbeam 41. This increases the contact area between the front crossbeam 41 and the roof body 21, ensuring that the front crossbeam 41 provides support for the roof body 21. Furthermore, the roof body 21 can cover the front crossbeam 41 from above. During assembly, only the front edge of the roof body 21 needs to be sealed against the front component, thereby improving the sealing performance of the vehicle 1000.

[0102] In some embodiments of the present application, as shown in FIG. 4 , one of the plurality of roof crossbeams 40 is a front crossbeam 41 , and the front crossbeam 41 includes a first upper plate 411 and a first lower plate 412 .

[0103] Specifically, both ends of the first upper plate 411 in the left and right directions extend to connect with the top frame reinforcement beams 30 on both sides, and the first lower plate 412 is arranged on the lower side of the first upper plate 411, and both ends of the first lower plate 412 in the left and right directions extend to connect with the cross beam connection part 112.

[0104] In this way, when one of the first upper plate 411 and the first lower plate 412 fails to be connected to the side panel assembly 10, the other can still provide support for the top cover outer panel 20, thereby improving the reliability of the front cross beam 41 supporting the top cover outer panel 20. At the same time, the first upper plate 411 and the second upper plate 422 can both play a supporting role, thus improving the strength of the front cross beam 41, thereby improving the strength of the cabin frame 100, and further improving the safety of the vehicle 1000.

[0105] In some embodiments of the present application, as shown in FIG13 , one of the multiple roof crossbeams 40 is a rear crossbeam 42, which is connected to the roof outer panel 20 and disposed on the lower side of the rear end of the roof outer panel 20. In other words, the rear end of the roof outer panel 20 extends rearwardly beyond the upper end surface of the rear crossbeam 42. This increases the contact area between the rear crossbeam 42 and the roof outer panel 20, ensuring that the rear crossbeam 42 provides support for the roof outer panel 20. Furthermore, the roof outer panel 20 can cover the rear crossbeam 42 from above. During assembly, only the rear end of the roof outer panel 20 needs to be sealed against the rear components, thereby improving the sealing performance of the vehicle 1000.

[0106] In some embodiments of the present application, as shown in FIG13 , the rear crossbeam 42 is provided with a hinge fixing portion 421. The hinge fixing portion 421 is spaced apart from the top cover outer panel 20. The hinge fixing portion 421 of the top cover outer panel 20 encloses an installation space. The hinge fixing portion 421 is used to install the rear tailgate hinge 4211. The installation space is suitable for accommodating at least a portion of the rear tailgate hinge 4211. Thus, the top cover outer panel 20 can provide a shield for the rear tailgate hinge 4211, reducing the probability of impurities in the external environment coming into contact with the rear tailgate hinge 4211, thereby reducing the probability of impurities in the external environment causing the rear tailgate hinge 4211 to fail, thereby improving the reliability of the vehicle 1000 during use. Furthermore, there is no need to install a separate shielding member to shield the rear tailgate hinge 4211, thereby reducing production costs and the design difficulty of the vehicle 1000.

[0107] In some embodiments of the present application, as shown in FIG. 13 , the rear cross beam 42 includes a second upper plate 422 and a second lower plate 423 .

[0108] Specifically, the second upper plate 422 includes a first upper beam plate 4221, a second upper beam plate 4222 and a third upper beam plate 4223. The first upper beam plate 4221 is arranged horizontally and extends front to back. At least part of the upper side surface of the first upper beam plate 4221 is formed as a fixed surface. The second upper beam plate 4222 is connected to the rear end of the first upper beam plate 4221 and extends downward. The third upper beam plate 4223 is connected to the lower end of the second upper beam plate 4222 and extends rearward. The second lower plate 423 includes a first lower beam plate 4231, The second lower beam plate 4232 and the third lower beam plate 4233, the first lower beam plate 4231 extends forward and backward and is fixed to the lower side surface of the front end of the first upper beam plate 4221, the front end of the second lower beam plate 4232 is connected to the rear end of the first lower beam plate 4231 and the rear end extends downward and backward, the third lower beam plate 4233 is connected to the rear end of the second lower beam plate 4232 and extends backward, the rear end of the third lower beam plate 4233 is fixed to the lower surface of the third upper beam plate 4223 and forms a hinge fixing portion 421.

[0109] Thus, an installation space can be defined between the hinge fixing portion 421 and the top cover outer panel 20. During the product design process, by adjusting the dimensions, relative angles and other parameters of the first upper beam plate 4221, the second upper beam plate 4222, the third upper beam plate 4223, the first lower beam plate 4231, the second lower beam plate 4232 and the third lower beam plate 4233, a sufficient gap can be created between the rear tailgate hinge 4211 and the top cover outer panel 20, so that when the rear tailgate 200 rotates through the rear tailgate hinge 4211, the rear tailgate hinge 4211 and the rear tailgate 200 will not interfere with the top cover outer panel 20.

[0110] In some embodiments of the present application, as shown in FIG. 5 to FIG. 7 , the side panel assembly 10 is formed with a door sill 14 extending front to back, wherein a first sub-cavity 142 is defined in the door sill 14 , and a door sill beam 141 is provided in the first sub-cavity 142 .

[0111] During the use of the vehicle 1000, passengers enter and exit the vehicle 1000 through the door opening 13. During the process of entering and exiting the vehicle 1000, the passengers will inevitably step on the door sill 14. By setting the first sub-cavity 142, the first sub-cavity 142 can provide a layout space for the door sill beam 141. By setting the door sill beam 141, the door sill beam 141 can provide support so that the strength of the side panel assembly 10 at the door sill 14 meets the stepping requirements of the passengers. When the vehicle 1000 is hit, the door sill beam 141 can reduce the deformation of the side panel assembly 10 at the door sill 14, thereby reducing the probability of excessive deformation or even crushing of the cabin frame 100, and further improving the safety of the vehicle 1000.

[0112] In some embodiments of the present application, as shown in FIG5 , the lower end of the side panel outer panel 12 is connected to the lower end of the side panel inner panel 11 to form a first sub-cavity 142. In other words, the sill beam 141 is disposed below the sill 14. This reduces the probability that the retaining structure within the first sub-cavity 142 will fail to retain the sill beam 141, causing the sill beam 141 to roll within the first sub-cavity 142, thereby improving the reliability of the sill beam 141 in supporting the sill 14.

[0113] In some embodiments of the present application, as shown in FIG5 , a second sub-cavity 143 is further defined in the door sill 14 . In the height direction of the vehicle 1000 , at least part of the second sub-cavity 143 is higher than the first sub-cavity 142 . The first sub-cavity 142 is located on the side of the second sub-cavity 143 that is away from the passenger compartment in the left-right direction of the vehicle body.

[0114] That is, the outer sill 14 is shorter than the inner sill 14. It is understood that when a load is concentrated at a certain point on the sill 14, the sill 14 is more likely to deform. In this embodiment, when the vehicle 1000 is impacted, the lower outer sill 14 and sill beam 141 are impacted first. When the load on the outer sill 14 is transferred to the taller inner sill 14, the load is dispersed across the inner sill 14. This reduces the degree of deformation of the sill 14 of the side panel assembly 10 during an impact, thereby improving the safety of the vehicle 1000. Furthermore, the inner and outer sills 14 form a step, making it easier for passengers to enter and exit the vehicle 1000.

[0115] In some embodiments of the present application, the sill beam 141 is made of aluminum. Aluminum has a low density and stable chemical properties. By making the sill beam 141 of aluminum, it is possible to achieve a lightweight vehicle 1000 and increase the service life of the sill beam 141.

[0116] In some embodiments of the present application, as shown in Figures 5, 7, and 8, the side panel assembly 10 further includes an inner sill cover plate 15. The upper end of the inner sill cover plate 15 is connected to the side panel inner panel 11, and the lower end of the inner sill cover plate 15 extends outward toward the side panel outer panel 12. The lower end of the inner sill cover plate 15 is connected to the side panel outer panel 12. The inner sill cover plate 15 cooperates with the side panel inner panel 11 to define a second sub-cavity 143. This seals the upper and lower ends of the sill 14, thereby preventing impurities from the external environment from entering the sill 14. Furthermore, the inner sill cover plate 15 also provides support for the side panel assembly 10 in the area of ​​the sill 14, thereby further improving the strength of the side panel assembly 10 in the area of ​​the sill 14.

[0117] In some embodiments of the present application, as shown in FIG5 , the side inner panel 11 at the door sill 14 includes a battery pack mounting portion 144 adapted to connect to the battery pack 300. This allows the battery pack 300 to be mounted on the vehicle 1000 without extending beyond the chassis of the vehicle 1000 in the left and right directions.

[0118] In some embodiments of the present application, as shown in Figure 5, the side inner panel 11 at the door sill 14 position also includes a battery pack sealing portion 145, and the battery pack sealing portion 145 is suitable for being sealed and connected to the battery pack 300. It can be understood that during the use of the vehicle 1000, the vehicle body will inevitably shake and twist, which will cause the side inner panel 11 to collide with the battery pack 300. By providing the battery pack sealing portion 145, the battery pack sealing portion 145 can absorb a portion of the force between the side inner panel and the battery pack 300, thereby improving the sealing reliability of the upper surface of the battery pack 300, and further improving the reliability of the vehicle 1000 during use.

[0119] The battery pack seal 145 includes a sealing plate 1451 and a sealing foam 1452. The sealing plate 1451 is connected to the side panel 11, and the sealing foam 1452 is connected between the sealing plate 1451 and the battery pack 300. This further enhances the barrier effect of the battery pack seal 145 on the side panel 11 and the battery pack 300, thereby further improving the reliability of the vehicle 1000 during use.

[0120] In the height direction of the vehicle, the battery pack sealing portion 145 is located on the upper side of the battery pack mounting portion 144. In the width direction of the vehicle 1000, the battery pack sealing portion 145 is located on the side of the battery pack mounting portion 144 facing the passenger compartment. In this way, a portion of the battery pack 300 can be arranged in the space below the side inner panel 11 forming the door sill 14. In the left and right directions, the size of the battery pack 300 can be larger, thereby increasing the volume of the battery pack 300 arranged on the vehicle 1000. It can be understood that the larger the volume of the battery pack 300, the longer the battery life of the battery pack 300. Therefore, the battery life of the vehicle 1000 can be improved, thereby improving the user experience.

[0121] In some embodiments of the present application, as shown in Figure 5, the side outer panel 12 forming the door sill 14 includes: a first outer panel segment 121 and a second outer panel segment 122, the first outer panel segment 121 extends vertically, the second outer panel segment 122 is connected to the upper end of the first outer panel segment 121 and extends along the left and right directions toward the side inner panel 11, and the lower end of the inner door sill sealing plate 15 is connected to the inner end of the second outer panel segment 122.

[0122] The side inner panel 11 forming the door sill 14 includes: a first inner panel section 113, a second inner panel section 114 and a third inner panel section 115. The first inner panel section 113 is vertically arranged, and the lower end of the first inner panel section 113 is connected to the lower end of the first outer panel section 121. One end of the second inner panel section 114 is connected to the upper end of the first inner panel section 113 and the other end extends toward one side of the passenger compartment in the left and right direction. The third inner panel section 115 is connected to the inner end of the second inner panel section 114 and extends upward. The upper end of the third inner panel section 115 is connected to the upper end of the inner door sill sealing plate 15.

[0123] The inner door sill cover plate 15 includes: a first cover plate section 151, a second cover plate section 152 and a third cover plate section 153. The lower end of the first cover plate section 151 is connected to the side panel outer panel 12 and the upper end extends vertically upward. The upper end of the third cover plate section 153 is connected to the side panel inner panel 11 and the lower end extends vertically downward. The second cover plate section 152 extends left and right, and the left and right ends of the second cover plate section 152 are respectively connected to the upper end of the first cover plate section 151 and the lower end of the third cover plate section 153.

[0124] In this way, the connection between the side panel outer panel 12, the side panel inner panel 11 and the inner door sill cover 15 at the door sill 14 position can be achieved, and the side panel outer panel 12, the side panel inner panel 11 and the inner door sill cover 15 can define a first sub-cavity 142 and a second sub-cavity 143.

[0125] During the product design process, the dimensions and relative angles of the first outer panel section 121, the second outer panel section 122, the first inner panel section 113, the second inner panel section 114, the third inner panel section 115, the first sealing panel section 151, the second sealing panel section 152 and the third sealing panel section 153 and other parameters can be adjusted to meet more product design requirements and reduce the difficulty of product design.

[0126] In some embodiments of the present application, as shown in FIG. 5 , the second inner plate segment 114 includes a first flat plate portion 1141 , a second flat plate portion 1142 , a third flat plate portion 1143 , a first vertical plate portion 1144 and a second vertical plate portion 1145 .

[0127] Specifically, the first flat plate portion 1141, the second flat plate portion 1142 and the third flat plate portion 1143 all extend in the left-right direction and are arranged in sequence from bottom to top. One end of the first flat plate portion 1141 is connected to the upper end of the first inner plate section 113, one end of the third flat plate portion 1143 is connected to the lower end of the third inner plate section 115, the upper end of the first vertical plate portion 1144 is connected to the end of the second flat plate portion 1142 facing the side outer panel 12, and the lower end extends vertically downward to be connected to the other end of the first flat plate portion 1141, the lower end of the second vertical plate portion 1145 is connected to the other end of the second flat plate portion 1142 away from the side outer panel 12, and the upper end of the second vertical plate portion 1145 extends vertically upward to be connected to the other end of the third flat plate portion 1143.

[0128] After the assembly is completed, the second inner panel section 114 provides support for the threshold beam 141 at the bottom. By providing the first flat plate portion 1141, the second flat plate portion 1142, the third flat plate portion 1143, the first vertical plate portion 1144 and the second vertical plate portion 1145, the shape of the second inner panel section 114 can be adapted to the shape of the threshold beam 141. The second inner panel section 114 can cooperate with the threshold beam 141 from different directions, thereby improving the stability of the connection between the second inner panel section 114 and the threshold beam 141 and the position accuracy of the second inner panel and the threshold beam 141 after assembly.

[0129] In some embodiments of the present application, as shown in FIG5 , a second inner panel flange 116 is formed at the upper end of the side panel inner panel 11, extending toward the side panel outer panel 12. A first panel flange 154 is formed at the upper end of the inner sill cover 15, extending toward the side panel inner panel 11. The first panel flange 154 extends to the underside of the second inner panel flange 116 and is fixedly connected to the underside surface of the second inner panel flange 116. This increases the contact area between the first panel flange 154 and the second inner panel flange 116, thereby improving the reliability of the connection between the upper end of the side panel inner panel 11 and the upper end of the inner sill cover 15, as well as the reliability of the seal between the side panel inner panel 11 and the inner sill cover 15.

[0130] In some embodiments of the present application, the second inner panel flange 116 is bonded to the first cover panel flange 154. The bonding process is convenient and can achieve a sealed connection, thereby improving production efficiency and achieving a sealed connection between the second inner panel flange 116 and the first cover panel flange 154.

[0131] In some embodiments of the present application, as shown in Figure 5, the first outer panel segment 121 is fitted with the first inner panel segment 113, so that the contact area between the first outer panel segment 121 and the first inner panel segment 113 can be larger, which can improve the reliability of the connection between the first outer panel segment 121 and the first inner panel segment 113 and the structural stability of the door sill. A stop flange is formed at the lower end of the first outer panel segment 121, and the stop flange extends away from the side inner panel 11, so that the strength of the first outer panel segment 121 can be improved.

[0132] In some embodiments of the present application, as shown in FIG5 , a second cover flange 155 extending laterally toward the outside of the vehicle body is formed at the lower end of the inner sill cover plate 15. The second cover flange 155 is fixedly connected to the upper surface of the sill beam 141. Thus, both the upper and lower ends of the sill beam 141 are fixed, thereby improving the reliability and stability of the sill beam 141 when mounted on the vehicle body.

[0133] In some embodiments of the present application, as shown in FIG5 , an upwardly folded outer panel flange 1221 is formed on the end of the second outer panel segment 122 facing the interior of the vehicle. The inner surface of the outer panel flange 1221 is fixedly connected to the outer surface of the inner sill cover 15 , and the upper surface of the second cover flange 155 is fixedly connected to the lower surface of the second outer panel segment 122 . This increases the contact area between the side panel outer panel 12 and the inner sill cover 15 , thereby improving the reliability of the connection and the sealing between the side panel outer panel 12 and the inner sill cover 15 . Furthermore, the side panel outer panel 12 and the inner sill cover 15 mate in different directions, thereby improving the positional accuracy of the connected side panel 12 and the inner sill cover 15 . The upper end of the outer panel flange 1221 is formed with an outer panel fold, thereby improving the strength of the outer panel flange 1221 .

[0134] In some embodiments of the present application, the side outer panel 12 has a snap-fit ​​flange extending toward the center of the door opening 13. The snap-fit ​​flange extends circumferentially around the door opening 13 and is configured to snap fit a sealing strip extending circumferentially around the door opening 13. The snap-fit ​​connection is convenient and reliable, thereby improving production efficiency and ensuring the reliability of the sealing strip's connection around the door opening 13. The sealing strip abuts between the vehicle door and the vehicle body, ensuring a seal between the door and the vehicle body when the door is closed.

[0135] In some embodiments of the present application, the width of the snap-fit ​​flange is 10 mm to 20 mm. The width of the snap-fit ​​flange refers to the dimension of the snap-fit ​​flange toward the center of the door opening 13. For example, the width of the snap-fit ​​flange can be 10 mm, 11 mm, 13 mm, 16 mm, or 20 mm. This ensures that there is sufficient space on the snap-fit ​​flange for installing the sealing strip, and the snap-fit ​​flange does not encroach too much on the door opening 13, thereby providing sufficient space for passengers to enter and exit the vehicle 1000.

[0136] In some embodiments of the present application, as shown in FIG5 , a seat cross member connecting plate 16 is further provided on the side of the side panel inner panel 11 that forms the door sill 14 and faces the vehicle interior. The provision of the seat cross member connecting plate 16 connects the seat cross member to the side panel assembly 10, thereby enabling installation of the seat on the vehicle 1000.

[0137] In some embodiments of the present application, as shown in Figures 9, 10 and 12, the side panel inner panel 11 and the side panel outer panel 12 are connected to form an A-pillar 123 and a C-pillar 124, and the side panel assembly 10 also includes: an inner panel reinforcement plate 1231, a B-pillar reinforcement plate 1241 and a C-pillar reinforcement plate 1242.

[0138] Specifically, the inner panel reinforcement plate 1231 is arranged inside the A-pillar 123, the inner panel reinforcement plate 1231 is fixed to the side inner panel 11, the B-pillar reinforcement plate 1241 is arranged inside the C-pillar 124, the B-pillar reinforcement plate 1241 is fixed to the side inner panel 11, and the C-pillar reinforcement plate 1242 is arranged inside the C-pillar 124 and connected between the side inner panel 11 and the side outer panel 12.

[0139] By setting the inner panel reinforcement plate 1231, when the load is transferred to the side panel assembly 10 at the A-pillar 123 position, the inner panel reinforcement plate 1231 can share part of the load, thereby further enhancing the strength of the side panel assembly 10 at the A-pillar 123 position and improving the safety of the vehicle 1000. Similarly, by setting the B-pillar reinforcement plate 1241, when the load is transferred to the C-pillar 124 position, the B-pillar reinforcement plate 1241 can share part of the load, thereby further enhancing the strength of the side panel assembly 10 at the C-pillar 124 position and improving the safety of the vehicle 1000.

[0140] By providing the C-pillar reinforcement plate 1242 , when the load is transferred to the C-pillar 124 position, the C-pillar reinforcement plate 1242 can share part of the load, thereby further enhancing the strength of the side panel assembly 10 at the C-pillar 124 position and improving the safety of the vehicle 1000 .

[0141] In some embodiments of the present application, as shown in FIG3 , the upper end of the B-pillar reinforcement plate 1241 is connected to the roof frame reinforcement beam 30. This further improves the strength of the vehicle body. When the vehicle 1000 is hit, the force can be transferred between the B-pillar reinforcement plate 1241 and the roof frame reinforcement beam 30, thereby reducing the probability of excessive force concentration at a single location, causing excessive deformation of the vehicle body, and further improving the safety of the vehicle 1000.

[0142] In some embodiments of the present application, as shown in Figures 9 and 10, the side panel assembly 10 further includes an inner sill cover 15, which extends forward and backward. The upper and lower ends of the inner sill cover 15 are respectively connected to the side panel inner panel 11 and the side panel outer panel 12. The front end of the inner sill cover 15 extends into the A-pillar 123 and is connected to the inner panel reinforcement plate 1231. The rear end of the inner sill cover 15 extends into the C-pillar 124 and is connected to the B-pillar reinforcement plate 1241. In this way, a frame structure can be formed on the side of the vehicle body. When a certain part of the side of the vehicle body is hit, the entire side of the vehicle body can bear the force generated by the impact, thereby improving the structural strength of the side of the vehicle body and further enhancing the safety of the vehicle 1000.

[0143] In some embodiments of the present application, as shown in Figures 10 and 12 , the horizontal cross-section of the B-pillar reinforcement plate 1241 is an "X" shape, which can increase the strength of the B-pillar reinforcement plate 1241 and further improve the safety of the vehicle 1000.

By setting the first folding edge 1181, the first folding edge 1181 can increase the contact area between the front flange 118 of the inner panel and the side outer panel 12, thereby improving the reliability of the connection between the first folding edge 1181 and the side outer panel 12, and the first folding edge 1181 can further improve the strength of the side assembly 10 at the A-pillar 123 position. Similarly, by setting the second folding edge 1191, the second folding edge 1191 can increase the contact area between the rear flange 119 of the inner panel and the side outer panel 12, thereby improving the reliability of the connection between the first folding edge 1181 and the side outer panel 12, and the second folding edge 1191 can further improve the strength of the side assembly 10 at the C-pillar 124 position. Among them, the first folded edge 1181 is bonded to the side outer panel 12, and the second folded edge 1191 is bonded to the side outer panel 12. This can improve production efficiency and achieve a sealed connection between the first folded edge 1181 and the side outer panel 12, and the second folded edge 1191 and the side outer panel 12.
