Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile bodies, and in particular to a side wall assembly and a vehicle. BACKGROUND

[0002] Automobiles, as an important means of transportation, play an irreplaceable role in people's daily life. An automobile generally comprises a chassis, a body, a power assembly and a control system. In the prior art, a rocker beam is arranged at the bottom of the side wall of the automobile to buffer the impact from the side, thereby improving safety.

[0003] At present, the side wall generally comprises a side wall outer plate and a side wall inner plate, the side wall outer plate and the bottom of the side wall inner plate form a closed accommodating cavity, and the rocker beam is arranged in the accommodating cavity. In addition, manufacturers will also arrange a rocker beam support plate to improve the connection and support of the rocker beam in order to improve the structural strength of the rocker beam.

[0004] However, in the above prior art, a large number of structural parts and materials need to be arranged to ensure the connection stability and impact resistance of the rocker beam, which is poor in economy and also increases the weight of the vehicle. CONTENT OF THE UTILITY MODEL

[0005] The utility model at least solves one of the technical problems in the related art to some extent.

[0006] Therefore, the present application aims to provide a side wall assembly and a vehicle, which aims to change the connection relationship between the rocker beam and the side wall inner plate and the side wall outer plate through the novel structural design of the side wall assembly, reduce the weight of the vehicle while ensuring the overall strength of the vehicle, and realize lightweight. To solve the technical problem of large weight of the vehicle in the prior art.

[0007] To achieve the above purpose, the utility model provides a side wall assembly, comprising:

[0008] a side wall inner plate configured to be connected with a floor assembly;

[0009] a side wall outer plate arranged on the side of the side wall inner plate away from the floor assembly; the side wall outer plate and the bottom of the side wall inner plate form an accommodating cavity;

[0010] a connection assembly arranged in the accommodating cavity, the connection assembly comprising:

[0011] a lower connecting plate, the bottom of which is connected with the bottom of the side wall inner plate;

[0012] a rocker beam arranged in the accommodating cavity, the bottom of the rocker beam being connected with the top of the lower connecting plate;

[0013] The bottom of the side outer plate is attached to and connected to one side of the rocker beam away from the side inner plate; and at least part of the one side of the rocker beam away from the side inner plate is exposed.

[0014] In the technical scheme, in the prior art, the side assembly and the rocker assembly are two structures respectively, the support plate and the reinforcing beam mounting plate are arranged in the side assembly, and the rocker is connected with the support plate and the reinforcing beam mounting plate through bolts, nuts and other connecting members. The components are more. According to the scheme, the rocker beam is integrated in the side assembly, the number of required components is reduced, and the connection between the rocker beam and the side outer plate and the side inner plate can be realized only through the connecting assembly. Therefore, compared with the prior art, the cost is saved, the weight of the vehicle body is reduced, the lightweight of the vehicle body is realized, the installation process required during production is saved, and the production speed is improved. On this basis, the connection stability of the rocker beam is ensured through the design of the connecting assembly, so that the structural strength of the vehicle body is ensured. In addition, the rocker beam is partially exposed, so that the cross-sectional area of the rocker beam is larger, the collision energy is dispersed and absorbed through the larger cross-sectional area, and the damage of the impact force to the main structure of the vehicle body is effectively reduced. This design not only enhances the safety of the vehicle during side collision, but also reduces the impact on the passengers in the vehicle, and protects the integrity of the passenger compartment.

[0015] Moreover, the side outer plate does not completely cover the one side of the rocker beam away from the side inner plate, and the side outer plate can be directly welded with the rocker beam at the joint. Compared with the connecting bracket in the prior art, the number of connecting points is increased by several times, and the connection strength is improved.

[0016] In addition, in the prior art, there is a gap between the side outer plate and the rocker beam. In the present application, the side outer plate is directly attached to the rocker beam, so that the distance between the two rocker beams can be maximized without changing the distance between the two side outer plates in the vehicle. When the vehicle is subjected to lateral impact, the allowed collapse area of the rocker beam is also increased, thereby improving the stability and stiffness of the vehicle and the survival space of the passengers.

[0017] In some embodiments of the present application, the side outer plate and the side inner plate clamp and connect the top of the connecting assembly;

[0018] The bottom of the connecting assembly is attached to and connected to the side inner plate;

[0019] The connecting assembly is riveted to the rocker beam.

[0020] In the technical scheme, the main production line does not need to increase riveting equipment and gluing equipment, so that the cost of modifying the production line can be reduced. From the process aspect, low-cost co-line can be realized; from the design aspect, co-platform development can be realized.

[0021] In some embodiments of the present application, the threshold beam comprises:

[0022] an inner side cross beam;

[0023] an outer side cross beam, which is arranged on a side of the inner side cross beam away from the floor assembly;

[0024] riveting between the inner side cross beam and the outer side cross beam.

[0025] In the technical solution, compared with a whole threshold beam, the difficulty and cost of separately manufacturing the inner side cross beam and the outer side cross beam are lower, and production and manufacturing are facilitated. The inner side cross beam and the outer side cross beam are connected through a drilling and riveting process. The main production line does not need to increase riveting equipment and gluing equipment, and the cost of reforming the production line can be reduced. From the process aspect, low-cost co-line can be realized; from the design aspect, co-platform development can be realized.

[0026] In some embodiments of the present application, the width direction of the outer side cross beam is arranged vertically, and a side of the outer side cross beam away from the floor assembly is connected with the side wall outer plate; the width direction of the inner side cross beam is arranged horizontally, and a side of the inner side cross beam away from the floor assembly is connected with a side of the outer side cross beam away from the side wall outer plate, and the outer side cross beam and the inner side cross beam are perpendicular to each other.

[0027] In the technical solution, the cross section of the threshold beam is in the shape of T through the arrangement. Through the design, the area of the side of the outer side cross beam away from the floor assembly is larger, and when the vehicle is subjected to lateral impact, the outer side contact surface can be maximized during collision to fully contact the barrier to ensure the force bearing area. The inner side cross beam can bear stronger force in the width direction, and the force transmission channel to the seat cross beam can be smooth.

[0028] In some embodiments of the present application, the bottom end of the outer side cross beam is inclined downward away from the floor assembly.

[0029] In the technical solution, when subjected to impact, the bottom end of the outer side cross beam can bear a larger collapse space, so as to better protect the battery pack and reduce the possibility of failure, fire and explosion of the battery pack due to damage.

[0030] In some embodiments of the present application, the side wall inner plate is provided with a front door opening and a rear door opening.

[0031] The two ends of the inner side cross beam are respectively close to the two sides of the front door opening of the side wall inner plate.

[0032] In the technical solution, the vehicle has sufficient structural strength at the rear door, so that one section of the inner side cross beam can be omitted at the rear door opening to ensure the strength of the vehicle, save material cost, reduce the weight of the whole vehicle, and realize light weight.

[0033] In some embodiments of the present application, the side wall assembly further comprises a side wall reinforcement plate, which is arranged between the side wall outer plate and the side wall inner plate.

[0034] The side wall reinforcement plate comprises:

[0035] a first extension plate, the bottom of which is clamped and connected by the side wall outer plate and the rocker beam;

[0036] a second extension plate, which is arranged in parallel with the first extension plate; the bottom of the second extension plate is clamped and connected by the side wall outer plate and the rocker beam.

[0037] In the technical solution, the side wall reinforcement plate is used to increase the overall structural strength of the side wall assembly, which can absorb and disperse impact energy, prevent the deformation and shedding of the vehicle body, and thus protect the safety of the passengers in the vehicle. Moreover, unlike the prior art, in which the bottom end of the first extension plate and the second extension plate of the side wall reinforcement plate is also provided with a structural connection, in the present application, because the rocker beam and the connection structure of the rocker beam are changed, the bottom connection structure of the first extension plate and the second extension plate can be omitted, which not only ensures the overall structural strength, but also saves material cost, reduces the weight of the vehicle body, and realizes the lightweight of the vehicle body. In addition, the rocker beam is partially exposed, so the cross-sectional area of the rocker beam is larger, which disperses and absorbs the impact energy, thereby effectively reducing the damage of the impact force to the main structure of the vehicle body. This design not only enhances the safety of the vehicle in side collision, but also reduces the impact on the passengers in the vehicle, and protects the integrity of the passenger compartment.

[0038] In addition, the present application also provides a side wall assembly, which comprises:

[0039] a side wall inner plate for connecting with a floor assembly;

[0040] a connecting assembly arranged on the side of the side wall inner plate away from the floor assembly; the side wall assembly comprises:

[0041] a lower connecting plate, the bottom of which is connected with the bottom of the side wall inner plate;

[0042] a rocker beam arranged on the side of the side wall inner plate away from the floor assembly, the bottom of the rocker beam being connected with the top of the lower connecting plate;

[0043] a side wall outer plate arranged on the side of the rocker beam away from the side wall inner plate; the bottom of the side wall outer plate is attached to and connected with the side of the rocker beam away from the side wall inner plate, and at least part of the side of the rocker beam away from the side wall inner plate is exposed.

[0044] In the technical scheme, in the prior art, the side wall assembly and the rocker assembly are two structures respectively, the support plate and the reinforcing beam mounting plate are arranged in the side wall assembly, and the rocker is connected with the support plate and the reinforcing beam mounting plate through bolts, nuts and other connecting pieces. The components are more. Through the above scheme, the rocker beam is integrated in the side wall assembly, the number of required components is reduced, and the connection between the rocker beam and the side wall outer plate and the side wall inner plate can be realized only through the connecting assembly. Therefore, compared with the prior art, the cost is saved, the weight of the vehicle body is reduced, the lightweight of the vehicle body is realized, the installation process required during production is saved, and the production speed is improved. On this basis, the connection stability of the rocker beam is ensured through the design of the connecting assembly, so that the structural strength of the vehicle body is ensured.

[0045] Moreover, the side wall outer plate does not completely cover the side of the rocker beam away from the side wall inner plate, the side wall outer plate can be directly welded with the rocker beam at the joint, and the number of connection points is increased by several times compared with the connecting bracket in the prior art, and the connection strength is improved.

[0046] In addition, in the prior art, there is a gap between the side wall outer plate and the rocker beam. The side wall outer plate and the rocker beam in the application are directly attached, so that the distance between the two rocker beams can be maximized without changing the distance between the two side wall outer plates in the vehicle. When the vehicle is subjected to a lateral impact, the allowed collapse area of the rocker beam is also increased, so that the stability and stiffness of the vehicle are improved, and the survival space of the passengers is improved.

[0047] In some embodiments of the application, the rocker beam comprises:

[0048] A vertical section, which is vertically arranged in the width direction; the side of the vertical section away from the floor assembly is connected with the side wall outer plate;

[0049] A horizontal section, which is arranged on the side of the vertical section away from the floor assembly, and is horizontally arranged in the width direction; the side of the horizontal section away from the floor assembly is connected with the side of the vertical section away from the side wall outer plate.

[0050] In the technical scheme, the cross section of the rocker beam is T-shaped. Through this design, the area of the side of the vertical section away from the floor assembly is larger, which can ensure that the outer contact surface is maximized during collision when the vehicle is subjected to a lateral impact, so that it can fully contact the barrier and ensure the force area. The side of the vertical section away from the floor assembly does not need a large contact surface, and the width direction can bear stronger force, which can ensure smooth transmission of force to the seat cross beam.

[0051] In addition, the application also provides a vehicle comprising the side wall assembly as described above, the vehicle comprising a floor assembly, and the side wall assembly is arranged on one side of the floor assembly in the width direction.

[0052] The floor assembly comprises:

[0053] The floor assembly comprises:

[0054] The front compartment is arranged at the front end of the floor assembly.

[0055] In the technical scheme, the new side wall assembly structure improves the protection effect when the vehicle is subjected to a lateral impact. It not only improves the protection of the driver and passengers, but also improves the protection of the battery pack.

[0058] In the technical scheme, the impact force is transmitted to the inner cross beam from the outer cross beam, and then transmitted to the seat cross beam from the inner cross beam. Because the seat cross beam is located on the side of the inner cross beam away from the outer cross beam, the vertical direction of the seat cross beam is the force direction, ensuring the continuity of the force transmission channel.

[0059] In some embodiments of the application, the vehicle further comprises a battery pack, and the battery pack is arranged below the floor assembly;

[0060] The upper surface of the battery pack is not higher than the lower surface of the inner cross beam.

[0061] In the technical scheme, in the vehicle, the battery pack is located between the two outer cross beams. When a collision occurs, the protection is performed through the section of the outer cross beam below the inner cross beam, improving the protection effect of the battery pack.

[0070] The upper surface of the battery pack is not higher than the lower surface of the horizontal section.

[0071] In the technical scheme, in the vehicle, the battery pack is located between the two vertical sections. In the event of a collision, the protection is carried out through the section of the vertical section below the horizontal section, improving the protection effect of the battery pack.

When the vehicle is subjected to lateral impact, the rocker beam is used to withstand impact and absorb impact force, thereby achieving the effect of protecting the components and passengers inside the vehicle.

[0102] In the following, the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0103] Referring to all the drawings, in one illustrative embodiment of the side wall assembly of the present application, the side wall assembly comprises a side wall inner panel 200, which is configured to be connected with a floor assembly 900 of a vehicle. In the vehicle, the side wall inner panel 200 is a structure close to the interior of the vehicle, and the side wall inner panel 200 is closer to the driver and the passenger. In one aspect, the side wall inner panel 200, as a part of the vehicle body structure, provides necessary support and stability, ensuring the safety and stability of the vehicle during driving. On the other hand, in accidents such as side impact, the side wall inner panel 200 can absorb and disperse impact force, thereby protecting the safety of passengers in the vehicle.

[0104] In some embodiments, the side wall assembly further comprises a side wall outer panel 100, which is arranged on the side of the side wall inner panel 200 away from the floor assembly 900. In the vehicle, the side wall outer panel 100 is located on the side of the side wall inner panel 200 away from the driver and the passenger. In one aspect, the side wall outer panel 100, as an outer cover of the vehicle body, can effectively protect the internal structure of the vehicle body from erosion and damage by the external environment. On the other hand, in accidents such as side impact, the side wall outer panel 100 can also absorb and disperse impact force, thereby protecting the safety of passengers in the vehicle.

[0105] In some embodiments, the side wall outer panel 100 and the bottom of the side wall inner panel 200 form a receiving cavity 110. By arranging the receiving cavity 110, components can be arranged inside the receiving cavity 110 to improve the rigidity of the vehicle body or meet the needs of users, etc. Moreover, the space between the side wall outer panel 100 and the side wall inner panel 200 can help reduce noise and vibration, improving the ride comfort of the vehicle.

[0106] Please refer to Figure 4 and Figures 11 to 13 In some embodiments, the side wall assembly further comprises a connecting assembly 300, which is arranged in the receiving cavity 110 and has a mounting cavity in the middle. By arranging the connecting assembly 300, the remaining structures can be mounted into the receiving cavity 110 through the connecting assembly 300.

[0107] In some embodiments, the top end of the connecting assembly 300 is connected with the side wall outer panel 100. Or, the top end of the connecting assembly 300 is connected with the side wall inner panel 200. Or, the top end of the connecting assembly 300 is connected with both the side wall outer panel 100 and the side wall inner panel 200. By this design, the top of the connecting assembly 300 is fixed in the receiving cavity 110, which preliminarily ensures the stability of the connecting assembly 300 in the receiving cavity 110.

[0108] In some embodiments, the bottom end of the connecting assembly 300 is connected with the side outer panel 100. Or, the bottom end of the connecting assembly 300 is connected with the side inner panel 200. Or, the bottom end of the connecting assembly 300 is connected with both the side outer panel 100 and the side inner panel 200. By fixing the bottom of the connecting assembly 300 in the accommodating cavity 110, the connecting assembly 300 and the structure to be connected with the connecting assembly 300 are stably fixed in the accommodating cavity 110.

[0109] Please refer to Figures 1 to 5 and Figures 11 to 15 In some embodiments, the side assembly further comprises a rocker beam 400, which is arranged in the mounting cavity and connected with the connecting assembly 300. In this application, when the vehicle is subjected to a side impact, the rocker beam 400 can absorb and disperse the impact force, thereby effectively protecting the safety of the passengers inside the vehicle. The rocker beam 400 is an important part of the passive safety system of the vehicle, which can provide additional protection barrier for passengers. Secondly, as an important support point of the side of the vehicle body, the rocker beam 400 helps to enhance the overall rigidity of the vehicle body by providing additional structural support. This rigidity enhancement is crucial for the handling and stability of the vehicle, ensuring that the vehicle can maintain good dynamic performance during driving.

[0110] Please refer to Figures 1 to 4 In some embodiments, the bottom of the side outer panel 100 is attached to and connected with the side of the rocker beam 400 away from the side inner panel 200. So that at least part of the side of the rocker beam 400 away from the side inner panel 200 is exposed. That is, the side wall of the rocker beam 400 away from the side inner panel 200 is not completely covered by the side outer panel 100.

[0111] In some embodiments, the side outer panel 100 and the rocker beam 400 are connected by welding. In the prior art, the side outer panel 100 and the side inner panel 200 completely cover the rocker beam 400, and only riveting or the like can be used for connection. In this application, because the side outer panel 100 does not completely cover the rocker beam 400, welding can be used, which can increase the number of connection points by several times compared with the connecting bracket in the prior art, thereby improving the connection strength between the side outer panel 100 and the rocker beam 400, effectively preventing the possibility of failure in a collision, and without the need for riveting equipment in the production line.

[0112] In the prior art, the side wall assembly and the rocker assembly are two structures respectively, the support plate and the reinforcing beam mounting plate are arranged in the side wall assembly, and the rocker is connected with the support plate and the reinforcing beam mounting plate through bolts, nuts and other connecting pieces. There are more components. Through the above scheme, the rocker beam 400 is integrated in the side wall assembly, the number of required components is reduced, and the connection between the rocker beam 400 and the side wall outer plate 100 and the side wall inner plate 200 can be realized only through the connecting assembly 300. Therefore, compared with the prior art, the cost is saved, the weight of the vehicle body is reduced, and the lightweight of the vehicle body is realized. Meanwhile, the installation process required during production is saved, and the production speed is improved. On this basis, the connection stability of the rocker beam 400 is ensured through the design of the connecting assembly 300, so as to ensure the structural strength of the vehicle body.

[0113] In addition, in the prior art, there is a gap between the side wall outer plate 100 and the rocker beam 400. In the present application, the side wall outer plate 100 and the rocker beam 400 are directly attached, so that the distance between the two rocker beams 400 can be maximized without changing the distance between the two side wall outer plates 100 in the vehicle. When the vehicle is subjected to lateral impact, the allowed collapse area of the rocker beam 400 is also increased, thereby improving the stability and stiffness of the vehicle and increasing the survival space of the passengers. In addition, the rocker beam 400 is partially exposed, so the cross-sectional area of the rocker beam 400 is larger, and the impact energy is dispersed and absorbed through the larger cross-sectional area, thereby effectively reducing the damage of the impact force to the main structure of the vehicle body. This design not only enhances the safety of the vehicle in side impact, but also reduces the impact on the passengers in the vehicle, and protects the integrity of the passenger compartment.

[0114] Please refer to Figures 18 to 21 In some embodiments, the floor assembly 900 is the basis of the vehicle, so the front side of the vehicle is the front side of the floor assembly 900, the rear side of the vehicle is the rear side of the floor assembly 900, and the two sides of the vehicle in the width direction are the two sides of the floor assembly 900 in the width direction. The length of the floor assembly 900 is in the front-rear direction, that is, the front-rear direction of the vehicle. In the present application, the side wall assembly is arranged on one side of the floor assembly 900 in the width direction. Therefore, there are two side wall assemblies in one vehicle, which are symmetrically arranged on both sides of the floor assembly 900 in the width direction.

[0115] In some embodiments, the floor assembly 900 is horizontally arranged. The bottom of the side wall inner plate 200 is connected to the corresponding side edge of the floor assembly 900, and the side wall inner plate 200 extends upwards to the floor assembly 900.

[0116] In another embodiment, the floor assembly 900 is horizontally arranged as an example. The bottom of the side wall inner panel 200 is connected to the side of the floor assembly 901 corresponding to the side wall inner panel 200, and the height direction of the side wall inner panel 200 is perpendicular to the floor assembly 900. It is worth noting that because the side wall inner panel 200 is a component with curvature, its height direction can be considered as its approximate extension direction.

[0117] Please refer to Figures 1 to 3 In some embodiments, the extension direction of the side wall outer panel 100 is the same as the extension direction of the side wall inner panel 200. The side wall outer panel 100 and the side wall inner panel 200 are both provided with front and rear door openings. The front and rear door openings correspond after the side wall outer panel 100 and the side wall inner panel 200 are installed.

[0118] In some embodiments, the edges of the front and rear door openings of the side wall outer panel 100 have a flange. The side wall outer panel 100 can be connected to the side wall inner panel 200 through the flange. The flange refers to the flange of the vehicle body panel for the installation of the vehicle door sealing strip, which determines the size of the vehicle door space and also affects the overall performance of the vehicle door.

[0119] In some embodiments, the top edge of the side wall outer panel 100 can be connected to the top edge of the side wall inner panel 200, thereby ensuring the top connection strength of the side wall outer panel 100 and the side wall inner panel 200 and improving the structural strength of the side wall outer panel 100 and the side wall inner panel 200.

[0120] In some embodiments, the connection between the side wall outer panel 100 and the side wall inner panel 200 includes but is not limited to welding, riveting, and fusion.

[0121] In some embodiments, the cavity formed between the side wall outer panel 100 and the side wall inner panel 200 has a bottom that is a receiving cavity 110. The receiving cavity 110 is located at the side of the floor assembly 900 in the width direction, and through this design, the rocker beam 400 is ensured to be in the correct position, i.e., the rocker beam 400 is located at one side of the floor assembly 900 in the width direction, thereby ensuring that the rocker beam 400 can absorb impact force to protect the vehicle body components and the driver and passengers when the vehicle is subjected to a lateral impact.

[0122] Please refer to Figure 4 , Figure 16 and Figure 17 In some embodiments, the length direction of the connecting assembly 300 is the same as the length direction of the floor assembly 900, and the width direction of the connecting assembly 300 is the same as the height direction of the side wall inner panel 200. Alternatively, the width direction of the connecting assembly 300 extends upwardly from the floor assembly 900. Through this design, the installation of the connecting assembly 300 in the receiving cavity 110 is facilitated, and the through direction of the installation cavity is arranged along the width direction of the floor assembly 900, thereby facilitating the installation of the rocker beam 400.

[0123] Further, the connecting assembly 300 is arranged vertically to ensure that the direction of the lateral impact is perpendicular to the connecting assembly 300, at which the connecting effect and strength of the connecting assembly 300 are the largest, and the possibility of the failure of the connection of the connecting assembly 300 due to the force on one side is reduced.

[0124] It is worth noting that the specific shape of the connecting assembly 300 is not limited to a flat plate, and it can be bent according to the connection condition. Therefore, the width direction of the connecting assembly 300 is the general width direction of the connecting assembly 300 as a whole.

[0125] In some embodiments, the side outer panel 100 and the side inner panel 200 clamp the top of the connecting assembly 300. That is, the top of the connecting assembly 300 is located between the side outer panel 100 and the side inner panel 200, and the top of the connecting assembly 300 is clamped by the side outer panel 100 and the side inner panel 200 to limit the two sides of the connecting assembly 300, which further reduces the possibility of the connecting assembly 300 falling off the side outer panel 100 and the side inner panel 200 in the event of a collision, and ensures the strength of the structure.

[0126] Further, the edges of the front door opening and the rear door opening of the side inner panel 200 are also provided with a flange. The bottom flange of the side outer panel 100 and the bottom flange of the side inner panel 200 clamp the corresponding positions of the top of the connecting assembly 300, so as to ensure the limitation of the top of the connecting assembly 300 and the guarantee of the connecting strength.

[0127] In some embodiments, the connection between the side outer panel 100 and the top of the side outer panel 100, the side inner panel 200 and the connecting assembly 300 includes but is not limited to welding, fusion, riveting.

[0128] In some embodiments, the rocker beam 400 and the connecting assembly 300 are connected along the length direction of the connecting assembly 300 by a flow drill screwing process. The flow drill screwing process is abbreviated as FDS (Flow Drill Screwing). The principle of the flow drill screwing process is to melt the base material by using the heat generated by the high-speed rotation of the screw, to punch the base material by increasing the pressure, and to make threads on the base material, so as to fix two or more layers of sheet materials together. Compared with the prior art, the main production line does not need to add riveting equipment and gluing equipment, which can reduce the cost of modifying the production line. From the process aspect, low-cost co-line can be realized; from the design aspect, co-platform development can be realized.

[0129] In some embodiments, the bottom of the connecting assembly 300 is attached to the side of the side inner panel 200 away from the floor assembly 900; and the connection between the bottom of the connecting assembly 300 and the side inner panel 200 includes but is not limited to welding, fusion, riveting.

[0130] In some embodiments, the length direction of the mounting cavity is the same as the length direction of the floor assembly 900, the length direction of the rocker beam 400 is the same as the length direction of the floor assembly 900, and the width direction of the rocker beam 400 is the same as the width direction of the floor assembly 900. The rocker beam 400 is located in the mounting cavity, and the two sides of the width direction of the rocker beam 400 are located on the two sides of the connecting assembly 300, respectively. Through this design, the middle part of the rocker beam 400 is connected with the connecting assembly 300, so as to improve the stability after connection. And in the production installation, it is also more convenient to connect the connecting assembly 300 and the rocker beam 400.

[0131] In some embodiments, the interior of the rocker beam 400 includes a plurality of cavities. The multi-cavity structure of the rocker beam 400 can effectively disperse the stress of the rocker beam 400 when it is impacted by external force, thereby avoiding structural damage caused by excessive stress on a single point. This stress dispersion design enables the rocker beam 400 to maintain better structural integrity in extreme situations such as collisions.

[0132] In some embodiments, each cavity is arranged along the length direction of the rocker beam 400, and the two ends of each cavity pass through the end of the length direction of the rocker beam 400, respectively. This design is convenient for the production and manufacture of the rocker beam 400. On the other hand, by reasonably designing the number and shape of the cavities, the rigidity of the rocker beam 400 can be further enhanced, thereby improving the overall handling and stability of the vehicle.

[0133] Please refer to Figures 11 to 15 In some embodiments, the shape of the cavity in the cross section of the rocker beam 400 is rectangular. The purpose of using this shape is to facilitate production and manufacture.

[0134] In some embodiments, the shape of the cavity in the cross section of the rocker beam 400 is triangular. The use of this shape is based on the principle that a triangle has stability, thereby improving the impact resistance of the rocker beam 400.

[0135] Please refer to Figure 18 In some embodiments, the rocker beam 400 includes a vertical section 430, which is located on the side of the horizontal section 440 away from the floor assembly 900, the width direction of the vertical section 430 is arranged vertically, and the side of the vertical section 430 away from the floor assembly 900 is connected with the side wall outer plate 100.

[0136] The threshold beam 400 further comprises a horizontal section 440, which is horizontally arranged in the width direction, and is connected to the side of the vertical section 430 away from the side wall outer plate 100. In this way, the vertical section 430 and the horizontal section 440 are perpendicular to each other, so that the cross section of the threshold beam 400 is T-shaped. Through this design, the area of the side of the vertical section 430 away from the floor assembly 900 is larger, which can maximize the lateral contact surface during a side impact, so that it can fully contact the barrier and ensure the force bearing area. The horizontal section 440 can bear more force in the width direction, and can ensure smooth force transmission to the seat cross beam 903.

[0137] Further, the vertical section 430 and the horizontal section 440 of the threshold beam 400 can be integrally formed, which improves the overall structural strength of the threshold beam 400.

[0138] Further, the threshold beam 400 can be integrally formed by machining, casting or other processes.

[0139] In some embodiments, the cross section of the threshold beam 400 can be trapezoidal, the longer base of the trapezoid is connected to the side wall outer plate 100, the shorter base of the trapezoid faces the floor assembly 900, and the height of the trapezoid is arranged along the width direction of the floor assembly 900. It is worth noting that the cross section of the threshold beam 400 is a plane perpendicular to the threshold beam 400. Through this design, while ensuring that the lateral contact surface is maximized when the threshold beam 400 is impacted, the part of the threshold beam 400 corresponding to the inclined side of the trapezoid can transmit the impact force, thereby improving the force that the threshold beam 400 can bear.

[0140] Please refer to Figures 11 to 15 In some embodiments, the threshold beam 400 comprises an inner cross beam 420 and an outer cross beam 410, the length direction of the inner cross beam 420 is the same as that of the outer cross beam 410, and the inner cross beam 420 is connected to the outer cross beam 410. That is, the threshold beam 400 is a split structure formed by connecting the inner cross beam 420 and the outer cross beam 410. Through this scheme, compared with a whole threshold beam 400, it is easier and cheaper to manufacture the inner cross beam 420 and the outer cross beam 410 separately. The inner cross beam 420 and the outer cross beam 410 are connected by flow drilling and riveting process. The main production line does not need to add riveting equipment and gluing equipment, which can reduce the cost of transforming the production line. From the process aspect, low-cost co-line can be realized; from the design aspect, co-platform development can be realized.

[0141] Further, the outer cross beam 410 is arranged on the side of the inner cross beam 420 away from the floor assembly 900, and the width direction of the outer cross beam 410 is arranged vertically, and the side of the outer cross beam 410 away from the floor assembly 900 is connected with the side wall outer plate 100. The width direction of the inner cross beam 420 is arranged horizontally, and the side of the inner cross beam 420 away from the floor assembly 900 is connected with the side of the outer cross beam 410 away from the side wall outer plate 100, so as to form the outer cross beam 410 and the inner cross beam 420 perpendicular to each other. That is, the outer cross beam 410 and the inner cross beam 420 are connected to realize the technical scheme that the cross section of the rocker beam 400 is T-shaped. Through the design, the area of the side of the outer cross beam 410 away from the floor assembly 900 is larger, and when the vehicle is subjected to a lateral impact, the maximum contact area during the impact can be ensured, so that the contact with the obstacle is sufficient, and the stress area is ensured. The inner cross beam 420 can bear stronger force in the width direction, and can ensure smooth force transmission to the seat cross beam 903.

[0142] In some embodiments, the inner cross beam 420 is close to the side wall inner plate 200, and the outer cross beam 410 is close to the side wall outer plate 100; and the connection mode between the inner cross beam 420 and the outer cross beam 410 includes but is not limited to welding, riveting, fusion, etc.

[0143] In some embodiments, the inner cross beam 420 and the outer cross beam 410 are connected along the length direction by a flow drilling and riveting process. The outer cross beam 410 and the inner cross beam 420 each include a cavity, and the flow drilling and riveting process is used to connect the screws in the corresponding cavities of the outer cross beam 410 and the inner cross beam 420 through the corresponding side walls of the outer cross beam 410 and the inner cross beam 420. It is worth noting that the flow drilling and riveting process can also be used to connect the screws in the corresponding cavities of the inner cross beam 420 through the corresponding side walls of the outer cross beam 410 and the inner cross beam 420. Compared with the welding of the prior art, the number of connection points is increased, so as to improve the connection strength between the inner cross beam 420 and the outer cross beam 410, and improve the overall strength of the rocker beam 400.

[0144] In some embodiments, the inner cross beam 420 and the outer cross beam 410 are connected by the flow drilling and riveting process and also by welding. Because the flow drilling and riveting process passes the screws through the corresponding side walls of the outer cross beam 410 and the inner cross beam 420, the gap at the connection of the outer cross beam 410 and the inner cross beam 420 is not affected, and the joint of the outer cross beam 410 and the inner cross beam 420 can be welded by spot welding from the outside. By using multiple processes to achieve connection, the connection strength of the inner cross beam 420 and the outer cross beam 410 is further improved, and the structural strength of the rocker beam 400 is improved.

[0145] In some embodiments, the inner side beam 420 has a rectangular cross section, and the inner side beam 420 has at least two chambers inside. In the installed state, the chambers inside the inner side beam 420 are spaced apart along the width direction of the floor assembly 900.

[0146] In some embodiments, the outer side beam 410 has at least two chambers along the height direction in the installed state.

[0147] Because the battery pack of the electric vehicle is usually arranged below the floor assembly 900, in an embodiment of the present application, the bottom end of the outer side beam 410 is inclined downward away from the floor assembly 900. When impacted, the bottom end of the outer side beam 410 can have a larger collapse space to better protect the battery pack and reduce the possibility of failure, fire, and explosion of the battery pack due to damage.

[0148] In some embodiments, the outer side beam 410 has a top wall 411, and the top wall 411 is inclined downward away from the floor assembly 900. In the cross section of the outer side beam 410, the topmost chamber inside the outer side beam 410 is a right-angled trapezoid, and the hypotenuse of the right-angled trapezoid corresponds to and is parallel to the top wall 411 of the outer side beam 410. In order to meet the needs of aesthetics, user convenience, and door installation, the bottom of the front door opening and the rear door opening of the side outer panel 100 is designed as an inclined surface inclined downward away from the floor assembly 900. The present application corresponds the shape of the top wall 411 of the outer side beam 410 to the shape of the bottom of the front door opening and the rear door opening of the side outer panel 100, so as to avoid interference during installation.

[0149] In some embodiments, the outer side beam 410 further has a first side wall 412 and a second side wall 413, and the first side wall 412 and the second side wall 413 are vertically arranged and parallel to each other. The top end of the first side wall 412 is connected to the lower side of the top wall 411, and the top end of the second side wall 413 is connected to the higher side of the top wall 411. The bottom of the side outer panel 100 is attached to and connected to the first side wall 412 of the outer side beam 410.

[0150] Further, the side outer panel 100 has a flange at least at the bottom, and the flange is recessed toward the side inner panel 200. The flange at the bottom of the side outer panel 100 is attached to and connected to the first side wall 412. The flange facilitates the connection of the side outer panel 100 and the outer side beam 410, and because the flange is recessed toward the side inner panel 200, the part of the side outer panel 100 above the rocker beam 400 will protrude more outwardly than the rocker beam 400, and the side outer panel 100 will be impacted first when impacted, thereby absorbing and dissipating some impact force.

[0151] In some embodiments, the outer cross beam 410 further comprises a first inclined side wall 414, a second inclined side wall 415, a third side wall 416 and a bottom wall 417. The first inclined side wall 414 and the second inclined side wall 415 are inclined downwardly away from the floor assembly 900, and the third side wall 416 is parallel to the first side wall 412. The top end of the first inclined side wall 414 is connected to the bottom end of the first side wall 412, and the top end of the second inclined side wall 415 is connected to the bottom end of the second side wall 413. The top end of the third side wall 416 is connected to the bottom end of the first inclined side wall 414. The width direction of the bottom wall 417 is the same as the width direction of the floor assembly 900, and the two sides of the width of the bottom wall 417 are connected to the bottom end of the third side wall 416 and the bottom end of the second inclined side wall 415, respectively.

[0152] In some embodiments, the outer cross beam 410 has three chambers. In the cross section of the outer cross beam 410, the topmost chamber inside the outer cross beam 410 is a right-angled trapezoid as described above, and the middle chamber is between the first side wall 412 and the second side wall 413. The lowermost chamber is between the first inclined side wall 414, the second inclined side wall 415, the third side wall 416 and the bottom wall 417.

[0153] In some embodiments, the inner cross beam 420 is connected to the second side wall 413 in the outer cross beam 410 to achieve the connection between the inner cross beam 420 and the outer cross beam 410. Because the second side wall 413 is vertically arranged, the width direction of the inner cross beam 420 is the same as the width direction of the floor assembly 900 after the inner cross beam 420 is connected thereto, so as to ensure that the cross section of the rocker beam 400 is in the shape of a T.

[0154] Please refer to Figures 16 to 17 In some embodiments, the connecting assembly 300 comprises an upper connecting plate 301. The upper connecting plate 301 is in the shape of a rectangular plate, and the length direction thereof is the same as the length direction of the floor assembly 900, and the width direction thereof is vertically arranged. It can be considered that the width direction of the upper connecting plate 301 is the height direction thereof. The upper connecting plate 301 is parallel to the second side wall 413, and the side of the upper connecting plate 301 away from the floor assembly 900 is attached to the second side wall 413 of the outer side wall 100, and the upper connecting plate 301 is above the inner cross beam 420. A plurality of screws are penetrated through the upper connecting plate 301 and the second side wall 413 along the length direction of the upper connecting plate 301 by means of the flow drilling process, so as to achieve the connection between the top of the connecting assembly 300 and the rocker beam 400. In the production process, the connection between the top of the connecting assembly 300 and the rocker beam 400 can be achieved simply and quickly by this way, and the production efficiency is improved.

[0155] In some embodiments, the connecting assembly 300 further comprises an inclined portion 303, and a mounting cavity is formed between the upper connecting plate 301 and the inclined portion 303. The inclined portion 303 is inclined downward away from the floor assembly 900. The inclined portion 303 is parallel to the second inclined side wall 415, and the side of the inclined portion 303 away from the floor assembly 900 is attached to the second inclined side wall 415. A plurality of screws are drilled and riveted along the length direction of the inclined portion 303 to penetrate the inclined portion 303 and the second inclined side wall 415, so as to connect the bottom of the connecting assembly 300 and the rocker beam 400. In this way, the connection between the bottom of the connecting assembly 300 and the rocker beam 400 can be achieved simply and quickly during production, thereby improving production efficiency.

[0156] In some embodiments, the connecting assembly 300 further comprises a mounting portion 302, which is arranged at one end of the upper connecting plate 301 close to the front of the vehicle. The mounting portion 302 connects the corresponding end of the upper connecting plate 301 and the corresponding end of the inclined portion 303. The mounting portion 302 connects the upper connecting plate 301 and the inclined portion 303 to form an integral whole, and a space formed between the mounting portion 302, the upper connecting plate 301 and the inclined portion 303 is a mounting cavity. During mounting, only the inner cross beam 420 of the rocker beam 400 needs to be inserted into the mounting cavity, which facilitates production and improves production efficiency.

[0157] In another embodiment, the connecting assembly 300 can not be provided with the mounting portion 302, i.e., the upper connecting plate 301 and the inclined portion 303 are not connected, and the rocker beam 400 is connected by two separate components. In this form, the space between the upper connecting plate 301 and the inclined portion 303 is the mounting cavity.

[0158] In some embodiments, the connecting assembly 300 further comprises a lower connecting portion 304, which is arranged below the inclined portion 303 and parallel to the upper connecting plate 301. The bottom of the side wall inner plate 200 is provided with a downwardly extending flange, and the lower connecting portion 304 is attached to and connected to the bottom flange of the side wall inner plate 200. In this way, the bottom of the connecting assembly 300 is connected to the side wall inner plate 200, and the connection between the bottom of the connecting assembly 300 and the rocker beam 400 can be achieved simply and quickly, thereby improving production efficiency.

[0159] In some embodiments, the connecting assembly 300 can only comprise the upper connecting plate 301. The connecting assembly 300 can achieve the effect of fixing the rocker beam 400 in the accommodating cavity 110 by only comprising the upper connecting plate 301.

[0160] In some embodiments, the connecting assembly 300 comprises a lower connecting plate, wherein the lower connecting plate comprises the inclined portion 303 and the lower connecting portion 304 described above. That is, the technical solution that the bottom of the lower connecting plate is connected with the bottom of the side wall inner panel 200 and the bottom of the rocker beam 400 is connected with the top of the lower connecting plate is achieved. In this case, the connecting assembly 300 can only comprise the lower connecting plate, and the connection between the rocker beam 400 and the side wall inner panel 200 is achieved through the lower connecting plate. Since the rocker beam 400 is connected with the side wall outer panel 100, the effect that the rocker beam 400 is stably connected with the side wall inner panel 200 and the side wall outer panel 100 can be achieved only through the lower connecting plate.

[0161] In the prior art, the side wall outer panel 100 and the bottom of the side wall inner panel 200 are connected with each other, and the corresponding production line has been set in the factory. In the present application, the lower connecting plate is provided, and another purpose is to replace the part that the side wall outer panel 100 and the side wall inner panel 200 are connected at the lower part by the lower connecting plate. That is, in the original production line, the welding position of the side wall outer panel 100 and the bottom of the side wall inner panel 200 is consistent with the position to be welded between the lower connecting plate and the side wall inner panel 200 at present, so that the welding process of the production line is not changed, and the inline production is achieved.

[0162] In some embodiments, the vehicle has an A-pillar, a B-pillar and a C-pillar, the A-pillar is located at the front side of the front door opening, the B-pillar is located between the front door opening and the rear door opening, and the C-pillar is located at the rear side of the rear door opening. The A-pillar, the B-pillar and the C-pillar are well known in the art and will not be described here. The two ends of the inner side cross beam 420 are respectively close to the A-pillar and the B-pillar, that is, the inner side cross beam 420 can not be provided between the B-pillar and the C-pillar. Because the connection strength between the B-pillar and the C-pillar is high enough, the omission of one section of the inner side cross beam 420 can still ensure the strength of the vehicle, save material cost, reduce the weight of the vehicle, and achieve lightweight.

[0163] In some embodiments, the two ends of the inner side cross beam 420 are respectively close to the two sides of the front door opening of the side wall inner panel 200. That is, the inner side cross beam 420 can not be provided in the direction of the rear door of the side wall inner panel 200. The vehicle has sufficient structural strength at the rear door, so that the omission of one section of the inner side cross beam 420 at the rear door opening can still ensure the strength of the vehicle, save material cost, reduce the weight of the vehicle, and achieve lightweight.

[0164] Please refer to Figures 5 to 9 In some embodiments, the side wall assembly further comprises a side wall reinforcing plate 500, which is arranged in the cavity formed between the side wall outer panel 100 and the side wall inner panel 200. The side wall reinforcing plate 500 is used to increase the overall structural strength of the side wall assembly, which can absorb and disperse impact energy, prevent the vehicle body from deforming and falling off, and thus protect the safety of the passengers in the vehicle.

[0165] In some embodiments, the top of the side reinforcement plate 500 is clamped and connected by the side outer plate 100 and the side inner plate 200. And the side reinforcement plate 500 also corresponds to the front door opening and the rear door opening, and the edges of the side reinforcement plate 500 at the front door opening and the rear door opening are also clamped and connected by the side outer plate 100 and the side inner plate 200. In this way, the connection of the side reinforcement plate 500 with the side outer plate 100 and the side inner plate 200 is achieved.

[0166] In some embodiments, the connection mode between the side reinforcement plate 500 and the side outer plate 100 and the side inner plate 200 includes but is not limited to welding, riveting, and fusion.

[0167] In some embodiments, the side reinforcement plate 500 includes a first extension plate 501 and a second extension plate 502 which are parallel to each other, wherein the position of the first extension plate 501 corresponds to the A-pillar of the vehicle, and the position of the second extension plate 502 corresponds to the B-pillar of the vehicle. The bottom of the first extension plate 501 and the second extension plate 502 is clamped between the side outer plate 100 and the rocker beam 400. The bottom of the first extension plate 501 and the second extension plate 502 is connected with the side outer plate 100 and the rocker beam 400. In this way, the bottom connection of the side reinforcement plate 500 is ensured, the stability of the side reinforcement plate 500 in the overall structure is ensured, and the structural strength is improved. And unlike the prior art, the prior art has a structure or material connection at the bottom end of the first extension plate 501 and the second extension plate 502 of the side reinforcement plate 500, but in the present application, because the rocker beam 400 and the connection structure of the rocker beam 400 are changed, the bottom connection structure of the first extension plate 501 and the second extension plate 502 can be omitted, which saves material cost while ensuring the overall strength of the structure, reduces the weight of the vehicle body, and realizes the lightweight of the vehicle body.

[0168] Further, the bottom end of the first extension plate 501 and the second extension plate 502 is clamped between the first side wall 412 and the bottom of the side outer plate 100. Through this scheme, the first extension plate 501 and the second extension plate 502 are also connected with the rocker beam 400, further improving the connection strength of the rocker beam 400 and the reinforcement plate in the containing cavity 110.

[0169] Still further, the bottom lower surface of the first extension plate 501 and the second extension plate 502 is flush with the bottom lower surface of the side outer plate 100. While ensuring the clamping effect, the structure of the side reinforcement plate 500 is avoided from leaking out. Both the appearance is ensured and the waste of excess material is avoided.

[0170] In some embodiments, the connection mode between the bottom of the first extension plate 501 and the second extension plate 502 and the side outer plate 100 and the rocker beam 400 includes but is not limited to welding, riveting, and fusion.

[0171] Please refer toFigure 12 In some embodiments, the side wall assembly further comprises a front blocking plate 600, which is arranged in the receiving cavity 110 near the end of the front side of the floor assembly 900. It is used to prevent the rocker beam 400 from being separated from the receiving cavity 110. Because of the process problem, the side wall outer plate 100 and the side wall inner plate 200 need to be bent, so the end of the receiving cavity 110 will be an opening in communication with the outside. Therefore, the rocker beam 400 can be prevented from being separated from the receiving cavity 110 by the front blocking plate 600.

[0172] In some embodiments, the side wall assembly further comprises a front rocker reinforcement plate 700, which is arranged in the receiving cavity 110 near the end of the front side of the floor assembly 900. The front rocker reinforcement plate 700 is used to assist in improving the rigidity of the vehicle body.

[0173] Further, the front rocker reinforcement plate 700 is connected with the front blocking plate 600 and the side wall inner plate 200. The connection mode of the front rocker reinforcement plate 700 and the front blocking plate 600 includes but is not limited to welding, riveting, fusion, bolt connection. The connection mode of the front rocker reinforcement plate 700 and the side wall inner plate 200 includes but is not limited to welding, riveting, fusion, bolt connection.

[0174] Please refer to Figure 1 , Figure 5 , Figure 6 and Figure 10 In some embodiments, the side wall assembly further comprises a rear extension plate 800. The rear extension plate 800 is located on the side of the rocker beam 400 near the rear side of the floor assembly 900. The rear extension plate 800 is connected with the side wall inner plate 200 and the side wall outer plate 100. Through the rear extension plate 800, the rear wheel cover can be conveniently installed subsequently.

[0175] Further, the rear extension plate 800 at least partially seals the end of the receiving cavity 110 near the rear side of the floor assembly 900. Along the length direction of the rocker beam 400, the projection of the rocker beam 400 at least partially coincides with the projection of the rear extension plate 800. That is, when a collision occurs, even if the rocker beam 400 is loose, the rocker beam 400 is blocked by the rear extension plate 800, avoiding the rocker beam 400 from being separated from the receiving cavity 110.

[0176] Further, the inner side beam 420 can be directly used to abut against one side of the rear extension plate 800. Even if the rocker beam 400 is loose, the inner side beam 420 can abut against the rear extension plate 800, avoiding it from being separated from the receiving cavity 110.

[0177] In some embodiments, if no inner side beam 420 is arranged between the B-pillar and the C-pillar, i.e., no inner side beam 420 is arranged in the rear door direction of the inner side panel 200. A section of the inner side beam 420 can be arranged separately near the rear side of the floor assembly 900, and the section of the inner side beam 420 is located on one side of the rear extension plate 800. Even if the rocker beam 400 loosens, the inner side beam 420 can abut against the rear extension plate 800 to avoid disengaging from the accommodation cavity 110. While ensuring that the rocker beam 400 does not disengage from the accommodation cavity 110, lightweighting is achieved.

[0178] In some embodiments, the connection mode of the rear extension plate 800 with the inner side panel 200 and the outer side panel 100 includes but is not limited to welding, riveting, fusion, bonding.

[0179] In some embodiments, the inner side assembly further includes a front door hinge mounting plate arranged in the cavity between the outer side panel 100 and the inner side panel 200. More specifically, the front door hinge mounting plate is arranged between the side reinforcement panel 500 and the inner side panel 200. The plate-shaped part of the front door hinge mounting plate fixes the hinge and connects the door body and the door frame. Its main function is to support the weight of the door body and ensure that the door remains stable during opening and closing, while preventing the door body from sagging or shaking.

[0180] In some embodiments, the bottom end of the front door hinge mounting plate is clamped and connected by the side reinforcement panel 500 and the outer side beam 410. The connection mode between the front door hinge mounting plate and the side reinforcement panel 500 includes but is not limited to welding, riveting, fusion, bolt connection. The connection mode between the front door hinge mounting plate 302 and the rocker beam 400 includes but is not limited to welding, riveting, fusion, bolt connection.

[0181] In some embodiments, in the side assembly, in order to ensure the stability of the connection between the components, facilitate production and installation, avoid interference, and meet the requirements of dimensional tolerance, the components in the side assembly can have certain structures such as bending, curving, flanging, chamfering, rounding, etc.

[0182] In addition, referring to all the drawings, the present application also provides a side assembly, which includes an inner side panel 200 for connecting with a floor assembly 900 of a vehicle. In the vehicle, the inner side panel 200 is a structure close to the interior of the vehicle, and the inner side panel 200 is closer to the driver and the passengers. In one aspect, the inner side panel 200 as part of the vehicle body structure provides the necessary support and stability to ensure the safety and stability of the vehicle during driving. On the other hand, in accidents such as side impact, the inner side panel 200 can absorb and disperse the impact force, thereby protecting the safety of the passengers in the vehicle.

[0183] In some embodiments, the side wall assembly further comprises a connecting assembly 300, which is arranged on the side of the side wall inner plate 200 away from the floor assembly 900.

[0184] In some embodiments, the connecting assembly 300 comprises a lower connecting plate, the bottom of which is connected to the bottom of the side wall inner plate 200.

[0185] In some embodiments, the side wall assembly further comprises a rocker beam 400, which is arranged on the side of the side wall inner plate 200 away from the floor assembly 900, and the bottom end of the rocker beam 400 is connected to the top of the lower connecting plate. When the vehicle is subjected to a side collision, the rocker beam 400 can absorb and disperse the impact force, thereby effectively protecting the safety of the passengers in the vehicle.

[0186] In some embodiments, the side wall assembly further comprises a side wall outer plate 100, which is arranged on the side of the rocker beam 400 away from the side wall inner plate 200; the bottom of the side wall outer plate 100 is attached to and connected to the side of the rocker beam 400 away from the side wall inner plate 200, and at least part of the side of the rocker beam 400 away from the side wall inner plate 200 is exposed.

[0187] The present application integrates the rocker beam 400 into the side wall assembly, reduces the number of components required, and achieves the connection of the rocker beam 400 with the side wall outer plate 100 and the side wall inner plate 200 through the connecting assembly 300. Therefore, compared with the prior art, the cost is saved, the weight of the vehicle body is reduced, and the lightweight of the vehicle body is realized. At the same time, the production process required during production is also saved, and the production speed is improved. In addition, the side wall outer plate 100 does not need to completely cover the side of the rocker beam 400 away from the side wall inner plate 200, and the material cost of the side wall outer plate 100 is also saved. In addition, in the prior art, there is a gap between the side wall outer plate 100 and the rocker beam 400. However, in the present application, the side wall outer plate 100 is directly attached to the rocker beam 400, so that the distance between the two rocker beams 400 can be maximized without changing the distance between the two side wall outer plates 100 in the vehicle. When the vehicle is subjected to a lateral impact, the allowed collapse area of the rocker beam 400 is also increased, thereby improving the stability and stiffness of the vehicle and increasing the survival space of the passengers. In addition, the rocker beam 400 is partially exposed, so the cross-sectional area of the rocker beam 400 is larger, and the impact energy is dispersed and absorbed through the larger cross-sectional area, thereby effectively reducing the damage of the impact force to the main structure of the vehicle body. This design not only enhances the safety of the vehicle during side collision, but also reduces the impact on the passengers in the vehicle, and protects the integrity of the passenger compartment.

[0188] In some embodiments, the threshold beam 400 comprises a vertical section 430 and a horizontal section 440. The vertical section 430 is vertically arranged in the width direction, and is connected to the side outer plate 100 away from one side of the floor assembly 900. The horizontal section 440 is horizontally arranged in the width direction, and is connected to the vertical section 430 away from the side outer plate 100 away from one side of the floor assembly 900. In this way, the vertical section 430 and the horizontal section 440 are perpendicular to each other, and the cross section of the threshold beam 400 is in the shape of a T. Through this design, the area of the vertical section 430 away from one side of the floor assembly 900 is large, which can ensure that the outer side contact surface is maximized during a side impact, so that it can fully contact the barrier and ensure the force area. The side of the vertical section 430 away from the floor assembly 900 does not need a large contact surface, and the width direction can withstand stronger force, which can ensure smooth force transmission to the seat beam 903.

[0189] In some embodiments, the threshold beam 400 can also comprise the outer side beam 410 and the inner side beam 420 described above, and the specific connection relationship is as described above.

[0190] In some embodiments, the side outer plate 100 and the side inner plate 200 also clasp the top of the connecting assembly 300.

[0191] Please refer to Figures 18 to 21 In addition, the application also provides a vehicle, which comprises a floor assembly 900, and a side assembly arranged on one side of the floor assembly 900 in the width direction.

[0192] In some embodiments, the vehicle further comprises a vehicle body, a power unit, a transmission system, a control system, etc. in addition to the floor assembly 900 and the side assembly, which are all conventional technical means in the field and will not be described here.

[0193] In some embodiments, the floor assembly 900 comprises a floor component 901, and the side edges of the floor component 901 in the width direction are connected to the side inner plate 200. It is worth noting that the front-rear direction and the width direction of the floor component 901 have been described above, and will not be described here. Through the connection of the floor component 901 and the side inner plate 200, the connection of the side assembly and the floor assembly 900 is achieved.

[0194] In some embodiments, the connection method of the floor component 901 and the side inner plate 200 includes but is not limited to welding, fusion, riveting.

[0195] In some embodiments, the floor assembly 900 further comprises a front compartment 902 arranged at the front end of the floor component 901. The front compartment 902 provides a mounting space for the power unit of the vehicle. In addition, it also has multiple functions such as protecting internal parts, sound and heat insulation, air flow guiding, and collision energy absorption.

[0196] In some embodiments, each floor assembly 900 is provided with symmetrical side assemblies on both sides in the width direction.

[0197] In some embodiments, the floor assembly 900 further comprises a seat crossbeam 903 arranged on the floor assembly 901. The main function of the seat crossbeam 903 is to provide stable support for the seat, ensuring the comfort and safety of the passengers during the ride. The seat crossbeam 903 can resist deformation and displacement of the seat when subjected to external forces, thereby protecting the passengers from injury.

[0198] In some embodiments, the two ends of the seat crossbeam 903 are respectively connected to the corresponding inner side panels 200. In this way, the seat crossbeam 903 is connected to the side assembly, improving the structural strength.

[0199] Please refer to Figure 21 In some embodiments, the ends of the seat crossbeam 903 are located on one side of the rocker beam 400. When the vehicle is subjected to a side impact, the rocker beam 400 is used to absorb the impact force, ensuring that the force transmission channel between the rocker beam 400 and the seat crossbeam 903 is smooth. Even if the rocker beam 400 is bent, the rocker beam 400 will move away from the impact point together with the seat crossbeam 903 and the passengers on the seat crossbeam 903. Avoiding the passengers being directly impacted.

[0200] In some embodiments, when the rocker beam 400 is composed of the inner side beam 420 and the outer side beam 410. The seat crossbeam 903 is located on the side of the inner side beam 420 away from the outer side beam 410, and the width direction of the inner side beam 420 is the same as the length direction of the seat crossbeam 903. The impact force is transmitted to the inner side beam 420 from the outer side beam 410, and then transmitted to the seat crossbeam 903 from the inner side beam 420. Because the seat crossbeam 903 is located on the side of the inner side beam 420 away from the outer side beam 410, the vertical direction of the seat crossbeam 903 is the force direction, ensuring the continuity of the force transmission channel.

[0201] In some embodiments, when the rocker beam 400 is a one-piece, the seat crossbeam 903 is located on the side of the horizontal section 440 away from the vertical section 430, and the width direction of the horizontal section 440 is the same as the length direction of the seat crossbeam 903. The impact force is transmitted to the seat crossbeam 903 through the horizontal section 440. Because the seat crossbeam 903 is located on the side of the horizontal section 440 away from the vertical section 430, the vertical direction of the seat crossbeam 903 is the force direction, ensuring the continuity of the force transmission channel.

[0202] In some embodiments, the vehicle further comprises a battery pack arranged below the floor assembly 901. The battery pack provides power for the entire vehicle.

[0203] In some embodiments, when the rocker beam 400 is composed of the inner side beam 420 and the outer side beam 410, the upper surface of the battery pack is not higher than the lower surface of the inner side beam 420. In the vehicle, the battery pack is located between the outer side beams 410 on both sides. In the event of a collision, the protection effect on the battery pack is improved by the section of the outer side beam 410 located below the inner side beam 420.

[0204] Further, the lower surface of the battery pack can not be lower than the bottom of the outer side beam 410. So that the two sides of the battery pack are completely protected by the rocker beam 400, reducing the possibility of damage to the battery pack.

[0205] In some embodiments, when the rocker beam 400 is a one-piece, the upper surface of the battery pack is not higher than the lower surface of the horizontal section 440. In the vehicle, the battery pack is located between the vertical sections 430 on both sides. In the event of a collision, the protection effect on the battery pack is improved by the section of the vertical section 430 located below the horizontal section 440.

[0206] Further, the lower surface of the battery pack can not be lower than the bottom of the vertical section 430. So that the two sides of the battery pack are completely protected by the rocker beam 400, reducing the possibility of damage to the battery pack.

[0207] The side wall assembly in the present application integrates the rocker beam 400 in the side wall assembly, reducing the number of components required, and the connection of the rocker beam 400 with the side wall outer panel 100, the side wall inner panel 200 and the side wall reinforcement panel 500 can be achieved only by the connecting assembly 300. This saves costs, reduces the weight of the vehicle body, and achieves lightweighting of the vehicle body. At the same time, it also saves the installation process required during production, improving production speed. The side wall outer panel 100 does not completely cover the side of the rocker beam 400 away from the side wall inner panel 200, saving the material of the side wall outer panel 100 and reducing the weight. And the side wall outer panel 100 can be directly welded with the rocker beam 400 at the joint, compared with the connecting bracket in the prior art, the number of connecting points is increased by several times, and the connection strength is improved.

[0208] And, the side wall outer panel 100 in the present application directly adheres to the rocker beam 400, so the spacing between the two rocker beams 400 can be maximized without changing the spacing between the two side wall outer panels 100 in the vehicle. When the vehicle is subjected to a lateral impact, the allowed collapse area of the rocker beam 400 is also larger, thereby improving the stability and stiffness of the vehicle and improving the survival space of the passengers.

[0209] The vehicle of the present application compared with the prior art improves the protection effect when the vehicle is subjected to a lateral impact through the new side wall assembly structure. It not only improves the protection of the driver and passengers, but also improves the protection of the battery pack.

[0210] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
