Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0044] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "height", "upper", "lower", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. The meaning of "a plurality" is two or more, and at least one means it can be one, two, or more, unless otherwise clearly and specifically defined. The terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0045] In the description of the present application, the width direction, height direction, and length direction are introduced to more clearly describe the shape and / or structure of each component in the vehicle body structure, as well as the connection relationship and / or relative positional relationship between components. In the drawings, the arrow marked with Y indicates the width direction Y, the arrow marked with Z indicates the height direction Z, and the arrow marked with X indicates the length direction X. It can be understood that the width direction Y, height direction Z, and length direction X can also be the opposite directions of the directions indicated by the corresponding arrows. It should also be noted that with the vehicle driver as a reference, the width direction Y corresponds to the left-right direction of the driver, the length direction X corresponds to the front-back direction of the driver, and the height direction Z is the up-down direction of the driver.

[0046] To facilitate passengers getting on and off the vehicle or providing a step support when the vehicle is parked, some luxury cars, commercial vehicles, and other vehicles with a relatively high body height may be equipped with side steps. As an introduction to the present application, some current situations are described here: Side steps are usually installed on the vehicle body chassis, occupying a relatively large amount of the lower body space. Especially for automatic side steps driven by electric means or the like, due to the setting of the drive structure, their volume is larger than that of fixed side steps, and the larger assembly connection surface occupies more lower body space. Therefore, they are generally applied to fuel vehicle models or range-extended vehicle models with a relatively small battery pack. For pure electric vehicle models, in order to improve the overall vehicle endurance, the battery pack will be made as large as possible, resulting in insufficient and suitable space on the chassis for installing automatic side steps. If installing an automatic side step occupies a large amount of chassis space, it will inevitably interfere with the layout space of the battery pack. Therefore, there is currently no pure electric vehicle model equipped with an automatic side step on the market.

[0047] In view of this, an embodiment of the present application provides a vehicle body structure. In this vehicle body structure, the side step occupies a relatively small layout space, enabling the coexistence of the side step and the large battery pack, and reducing the impact of the side step on the pure electric range of the whole vehicle.

[0048] Please refer to Figure 1 , Figure 1 , which schematically shows the brief structure of a vehicle in some embodiments of the present application. A part of the structure of this vehicle constitutes the vehicle body structure of the embodiment of the present application. Specifically, the vehicle body structure includes a vehicle body main body 100 and a side step device 200.

[0049] The vehicle body main body 100 can be a frame structure of the vehicle, which constitutes the skeleton or skeleton system of the vehicle and is a main structural component of the vehicle. The vehicle body main body 100 can be used to support and connect various components of the vehicle body including the roof, the side of the vehicle body, the front and rear chassis, etc., providing structural strength and rigidity for the vehicle to protect the safety of the occupants in the vehicle and the vehicle. Optionally, the vehicle body main body 100 can also include vehicle body sheets, that is to say, the structure completed in the "body-in-white" stage of the vehicle manufacturing process can be regarded as the vehicle body main body 100 described in the embodiment of the present application.

[0050] Please refer to again Figure 1 , in the embodiment of the present application, the vehicle body main body 100 includes a sill beam 110. The sill beam 110 is a longitudinal beam located on the side of the vehicle body main body 100, that is, the sill beam 110 is arranged on both sides of the vehicle body main body 100 along its width direction Y and extends approximately along the length direction X of the vehicle body main body 100. In Figure 1 the shown vehicle, the sill beam 110 is located below the door and connects the front and rear wheel arches. The main functions of the sill beam 110 include increasing the rigidity and stability of the vehicle body structure, providing additional side collision protection, and can also be used as a support point for the door to ensure the stability and safety of the door.

[0051] In some embodiments, in addition to including the sill beam 110, the vehicle body main body 100 can also include other parts of the vehicle body frame. For example, it can include vehicle body side panels, front and rear vehicle body enclosures, vehicle body columns (A-pillar, B-pillar, C-pillar, etc.), front and rear vehicle body cross beams and other structures.

[0052] Please refer to together with Figure 2 and Figure 3 , Figure 2 , which schematically shows the connection structure between the sill beam 110 and the side step device 200 in the vehicle body structure. Figure 3 For along Figure 2The structure obtained by rotating the sectional structure along line A-A counterclockwise by 90°. In the embodiment of the present application, the side step device 200 includes a connecting bracket 210 and a step body 220. The connecting bracket 210 is connected to the sill beam 110. Specifically, the connecting bracket 210 includes a mounting seat 211, and the mounting seat 211 is directly connected to the sill beam 110, thereby realizing the connection and assembly of the connecting bracket 210 and the sill beam 110. The step body 220 is connected to the side of the connecting bracket 210 away from the sill beam 110 to be connected to the sill beam 110 through the connecting bracket 210. Among them, the step body 220 is the component in the side step device 200 for vehicle passengers to directly step on, and the connecting bracket 210 is the component for connecting and mounting the step body 220 on the sill beam 110. The connecting bracket 210 is specifically installed and fixed to the sill beam 110 through its mounting seat 211. Optionally, at least part of the surface of the mounting seat 211 can be in contact with the surface of the sill beam 110, or fitting parts such as gaskets can be provided between the two to fill the connection gap.

[0053] Among them, along the height direction Z of the vehicle body main body 100, the orthographic projection of the mounting seat 211 on the vehicle body main body 100 is located on the sill beam 110. That is to say, when the mounting seat 211 is irradiated with light parallel to the height direction Z, the generated orthographic projection is completely on the surface of the sill beam 110, that is, the dimensions of the mounting seat 211 in the width direction Y and the length direction X are smaller than those of the sill beam 110, and its installation on the sill beam 110 will not exceed the width and length range of the sill beam 110. Thus, whether on the inner side (the side facing the middle of the vehicle chassis) or the outer side (the side facing the outside of the vehicle) of the sill beam 110, the mounting seat 211 will not protrude from the sill beam 110, enabling it to be stably installed on the sill beam 110, reducing the occupation of the lower body space of the vehicle, reducing interference with other components, and leaving more space. It can be understood that in this vehicle body structure, the side step device 200 is connected to the sill beam 110 of the vehicle body main body 100, that is, the side step device 200 is installed at a position on the vehicle body main body 100 close to the side of the vehicle, and the installation points are concentrated at the edge close to the width direction Y of the vehicle body main body 100. Thus, the space occupied by the side step device 200 in the width direction Y of the vehicle body main body 100 can be reduced, leaving more space for other components.

[0054] For new energy vehicles, especially pure electric vehicles and other vehicles, this vehicle body structure can leave more space for the battery pack. Thus, the battery pack of the vehicle can be made larger, and the capacity of the battery pack is larger, which is beneficial to improving the pure electric endurance of the whole vehicle.

[0055] It can be understood that generally, sill beams 110 are respectively provided on both sides of the vehicle body main body 100 in its width direction Y, and doors are provided above the two sill beams 110. In order to facilitate passengers to get on and off the vehicle, side pedal devices 200 can be respectively connected and arranged on the two sill beams 110.

[0056] Please refer to again Figure 3 , in some embodiments, the connecting bracket 210 further includes a connecting member 213 and a link mechanism 212. Among them, the mounting seat 211 is connected to the sill beam 110 through the connecting member 213. Optionally, the connecting member 213 can be structures such as bolts, buckles, welding parts, riveting parts, etc., and are respectively connected to the mounting seat 211 and the sill beam 110 by means of threaded connection, snap connection, welding, riveting, etc. The connecting member 213 can be arranged between the mounting seat 211 and the sill beam 110 and is respectively connected to the mounting seat 211 and the sill beam 110 on both sides thereof; or the connecting member 213 can respectively penetrate through the mounting seat 211 and the sill beam 110 to be respectively connected to the mounting seat 211 and the sill beam 110. The link mechanism 212 is connected to the mounting seat 211, and the pedal body 220 is connected to the side of the link mechanism 212 away from the mounting seat 211. Optionally, the link mechanism 212 can adopt a fixed or movable link structure. The fixed type means that the link mechanism 212 cannot move, and the pedal body 220 is always fixed at the deployed position by the link mechanism 212; the movable type means that the link mechanism 212 can move relative to the mounting seat 211 and / or the pedal body 220 so as to be able to drive the pedal body 220 to move between the deployed position and the retracted position, which is convenient for passengers to step on and improves the user experience. The moving method can include one or more of rotation, sliding, telescoping, etc.

[0057] In the above embodiments, by providing the mounting seat 211 and the connecting member 213, the connection between the mounting seat 211 and the sill beam 110 is realized through the connecting member 213. In this way, the connection stability between the connecting bracket 210 and the sill beam 110 can be effectively guaranteed, so that the side pedal device 200 is more stable in use and has a longer service life. And this structure can also reduce the difficulty of connection and assembly to a certain extent, improve the assembly efficiency, and is also convenient for maintenance.

[0058] Please refer to again Figure 3, in some embodiments, the sill beam 110 has an inner cavity 114, that is to say, the sill beam 110 is a hollow structure. To ensure rigidity, the sill beam 110 is usually made of high-strength steel or other alloy materials such as aluminum alloy. By setting the sill beam 110 as a hollow structure, it is beneficial to reduce the weight of the vehicle body main body 100, and thus can reduce the weight of the whole vehicle. In this embodiment, the vehicle body main body 100 further includes a reinforcing member 120, the reinforcing member 120 is disposed in the inner cavity 114 and is connected to the sill beam 110, and the reinforcing member 120 can enhance the structural strength of the sill beam 110. The connecting member 213 penetrates into the inner cavity 114 and is connected to the reinforcing member 120, so as to further improve the rigidity of the connection between the side step device 200 and the sill beam 110, make the installation of the side step device 200 more firm, and improve the use stability of the side step device 200.

[0059] Optionally, the connecting member 213 can penetrate into the inner cavity 114 and be connected to the reinforcing member 120 by means of welding, clamping, threaded connection, riveting, etc. As Figure 3 shown, in some embodiments, a nut 121 is fixedly provided on the reinforcing member 120, the connecting member 213 is adapted to be connected to the nut 121, and the reinforcing member 120 is connected through the nut 121. Among them, the nut 121 is connected to the reinforcing member 120 by welding, the connecting member 213 can be a bolt structure, and correspondingly, assembly holes are respectively provided on the mounting seat 211, the sill beam 110 and the reinforcing member 120. By sequentially passing the connecting member 213 through the assembly holes of the mounting seat 211, the sill beam 110 and the reinforcing member 120, it is connected to the nut 121. The difficulty of connection and assembly is reduced, and it is convenient for disassembly and maintenance, improving efficiency.

[0060] Please also combine Figure 3 and Figure 4 , Figure 4 schematically shows the structure of the side step device 200. In some embodiments, the connecting bracket 210 includes a plurality of connecting members 213, the sill beam 110 includes a plurality of reinforcing members 120, and each reinforcing member 120 is connected to at least one connecting member 213. By providing a plurality of connecting members 213, the connection stress between the side step device 200 and the sill beam 110 is dispersed, and the connection stability between the two is improved. By providing a plurality of reinforcing members 120, which are dispersedly arranged in the inner cavity 114, the structural strength of the sill beam 110 is further improved; and each reinforcing member 120 is connected to one or more connecting members 213, which can further improve the structural rigidity of each connection point, making the installation of the side step device 200 more firm.

[0061] Optionally, nuts 121 are respectively provided on a plurality of reinforcing members 120, and each connecting member 213 can be correspondingly connected to one nut 121, ensuring that the rigidity of the connection points between the side step device 200 and the sill beam 110 meets the load-bearing requirements, and being convenient for assembly and disassembly.

[0062] Please refer to again Figure 3 Figure 3 , in some embodiments, the sill beam 110 includes a first side wall 111, a second side wall 112 and a bottom wall 113. The first side wall 111 is disposed towards the outside of the vehicle body 100 in the width direction Y of the vehicle body 100. Wherein, the outside of the vehicle body 100 is the side where the passenger stands relative to the vehicle after getting off or before getting on the vehicle at the door, that is to say, the first side wall 111 is the outer edge of the sill beam 110. The second side wall 112 is disposed towards the inside of the vehicle body 100 in the width direction Y and is opposite to the first side wall 111, that is to say, the second side wall 112 is the inner edge of the sill beam 110 disposed towards the middle of the vehicle chassis. The bottom wall 113 is disposed between the first side wall 111 and the second side wall 112 and is respectively connected to the first side wall 111 and the second side wall 112, and the bottom wall 113 faces the ground. In this embodiment, the mounting seat 211 is disposed on the side of the second side wall 112 close to the first side wall 111 and is connected to the bottom wall 113. By mounting the mounting seat 211 on the bottom wall 113, the part of the mounting seat 211 exposed on both sides of the vehicle body can be reduced, and the influence on the appearance of the vehicle can be reduced. The mounting seat 211 is disposed on the side of the second side wall 112 close to the first side wall 111, which can reduce the influence on the space on the other side of the second side wall 112, that is, further reduce the influence on the space in the middle of the vehicle chassis. For a new energy vehicle, this setting can further increase the installation space of the battery pack and improve the pure electric driving range of the whole vehicle.

[0063] Please refer to again Figure 3 Figure 3 , in some embodiments, the mounting seat 211 is connected to the bottom wall 113 of the sill beam 110, reducing the part of the mounting seat 211 exposed on both sides of the vehicle body and reducing the influence on the appearance of the vehicle. Along the height direction Z of the vehicle body 100, the orthographic projection of the mounting seat 211 on the vehicle body 100 is located within the bottom wall 113. That is to say, when the mounting seat 211 is irradiated with light perpendicular to the bottom wall 113, the generated orthographic projection is completely within the bottom wall 113, and the mounting surface of the mounting seat 211 is small and does not exceed the range of the bottom wall 113. Thus, whether on the inner side or the outer side of the sill beam 110, the mounting seat 211 will not protrude from the sill beam 110, further avoiding interference with other components and leaving more space.

[0064] In some embodiments, a stepped structure is formed at the bottom of the sill beam 110. For example, the bottom wall 113 of the sill beam 110 is the stepped surface closer to the inside of the stepped structure. The stepped structure further includes another stepped surface disposed closer to the outside, and this another stepped surface is higher than the bottom wall 113 in the height direction Z. The mounting seat 211 can be connected to this another stepped surface, so that the side step device 200 can be received in the receiving space formed by the drop between this another stepped surface and the bottom wall 113, reducing the impact on the vehicle's passing ability.

[0065] Please refer to again Figure 4 , in some embodiments, the side step device 200 includes a plurality of connecting brackets 210, and the link mechanisms 212 of the plurality of connecting brackets 210 are respectively connected to the pedal body 220. Thus, by connecting all the plurality of connecting brackets 210 to the sill beam 110, the connection stability between the side step device 200 and the sill beam 110 can be improved, the stress of the connection can be dispersed, and the structural strength can be enhanced. Moreover, the pedal body 220 can be carried and fixed at different positions of the pedal body 220, ensuring the stability of the pedal body 220 and reducing the occurrence of situations such as the pedal body 220 tilting or breaking due to uneven stress during stepping.

[0066] In some embodiments, the side step device 200 further includes a driving mechanism 230. The driving mechanism 230 is connected to the link mechanism 212 of at least one connecting bracket 210 and is used to drive the link mechanism 212 so that the link mechanism 212 drives the pedal body 220 to move between the deployed position and the retracted position. In this embodiment, by setting the driving mechanism 230 to drive the link mechanism 212, the side step device 200 can be automatically deployed and retracted to form an automatic step. By installing this automatic side step device 200 on the sill beam 110, on the one hand, the driving mechanism 230 is closer to the side edge of the vehicle, which can effectively reduce the impact of the side step device 200 with a larger volume due to the addition of the driving mechanism 230 on the bottom space of the vehicle body. Correspondingly, in new energy vehicles, especially pure electric vehicles, more assembly space can be reserved for the battery pack, which is beneficial to increasing the battery pack capacity and improving the pure electric range of the whole vehicle. On the other hand, the sill beam 110 is a structural member that enhances the body structure strength and has a high stiffness. Installing the side step device 200 on the sill beam 110 makes full use of the characteristic of the sill beam 110 having a high structural strength, and can achieve more stable loading of the side step device 200 through it, improving the assembly and operation stability of the side step device 200, reducing the occurrence of situations such as tilting and shaking, and improving the user experience.

[0067] In some embodiments, in the deployed position, the pedal body 220 is located outside the vehicle body main body 100 for passengers to step on; in the retracted position, at least a part of the pedal body 220 is located below the sill beam 110 to retract the pedal body 220 and reduce the impact on driving. The side pedal device 200 is installed on the sill beam 110 so that in the deployed position, the pedal body 220 extends further outwards, making it more convenient for passengers to get on and off the vehicle and enhancing the user experience.

[0068] Optionally, for the case where the side pedal device 200 has only one connection bracket 210, the drive mechanism 230 can be installed on the mounting seat 211 of the connection bracket 210, and the output end of the drive mechanism 230 is in transmission connection with the linkage mechanism 212 of the connection bracket 210. For the case where the side pedal device 200 has multiple connection brackets 210, the drive mechanism 230 can be connected to only one of the connection brackets 210, installed on the mounting seat 211 of the connection bracket 210, and the output end is in transmission connection with the linkage mechanism 212 of the connection bracket 210. When the connection bracket 210 is driven by the drive mechanism 230 to move, the remaining connection brackets 210 move passively following it. Alternatively, the drive mechanism 230 can be connected to multiple connection brackets 210 respectively to synchronously drive the multiple connection brackets 210 to move.

[0069] Please also combine Figure 6 and Figure 7 , which respectively show the schematic structural diagrams of the side pedal device 200 when the pedal body 220 is in the retracted position and the deployed position; by driving the linkage mechanism 212 through the drive mechanism 230 to make the linkage mechanism 212 move, the pedal body 220 can be driven to extend outwards to the Figure 7 shown deployed position; by driving the linkage mechanism 212 in the reverse direction through the drive mechanism 230 to make the linkage mechanism 212 move in the reverse direction, the pedal body 220 can be driven to retract inwards to the Figure 6 shown retracted position.

[0070] As Figure 4As shown, in some embodiments, the link mechanism 212 includes a first driven part 2121, a second driven part 2122, and a rotating part 2123. The first driven part 2121 is connected to the pedal body 220; the second driven part 2122 is disposed between the mounting seat 211 and the first driven part 2121 and is rotatably connected to the mounting seat 211 and the first driven part 2121 respectively; the rotating part 2123 is disposed between the mounting seat 211 and the first driven part 2121 and is rotatably connected to the mounting seat 211 and the first driven part 2121 respectively. The rotating part 2123 is connected to the driving mechanism 230 and is used to drive the rotating part 2123 to rotate. Through the rotational connection structure of the mounting seat 211, the first driven part 2121, the second driven part 2122, and the rotating part 2123, a linkage structure substantially in the shape of a quadrilateral is formed. When the driving mechanism 230 drives the rotating part 2123 to rotate, the rotational force is transmitted among the rotating part 2123, the mounting seat 211, the first driven part 2121, and the second driven part 2122, so that the rotating part 2123, the mounting seat 211, the first driven part 2121, and the second driven part 2122 are interlocked with each other, and further the first driven part 2121 can drive the pedal body 220 to move between the deployed position and the retracted position.

[0071] Optionally, the driving mechanism 230 may adopt a motor. By the motor outputting a driving force, the link mechanism 212 is driven to move, and further the pedal body 220 is driven to move. Alternatively, the driving mechanism 230 may also adopt a device such as an electric push rod, a cylinder, or an oil cylinder that can provide a driving force, and specifically can be selected according to actual requirements.

[0072] Optionally, the driving mechanism 230 adopts a structure of a motor and a gear transmission. The rotation of the motor drives the gear to rotate, and further drives the rotating part 2123 engaged with the gear to rotate around its rotation axis. Alternatively, the driving mechanism 230 adopts a structure of a motor and a belt transmission. The rotation of the motor drives the belt on the pulley to rotate, and further drives the rotating part 2123 driven by the belt to rotate around its rotation axis.
