DETAILED DESCRIPTION

[0039] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0040] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0042] In the description of the present application, “plurality” means two or more than two, unless otherwise precisely and specifically specified.

[0043] The terms "first", "second", "third", "fourth", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0044] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0045] As mentioned in the background art, the vehicle threshold structure in the related art has the problem of complex installation and affects the vehicle assembly efficiency. The inventor has found through research that the reason for this problem is that the existing vehicle threshold structure includes a threshold body connected to the vehicle floor, a threshold beam and a support plate arranged in the threshold body, and the threshold beam is located below the vehicle door and is hollow. The support plate is arranged inside the threshold beam as a reinforcement structure to improve the bending resistance of the threshold beam, thereby improving the column collision performance of the threshold structure.

[0046] When installing the above structure, the threshold body needs to be installed first, and then the threshold beam needs to be installed on the threshold body, and then the support plate needs to be installed in the threshold beam to enable it to have the function of absorbing collision force.

[0047] However, assembling the rocker structure of the vehicle and the vehicle through the above process will add more complicated steps, resulting in low assembly efficiency of the vehicle.

[0048] Based on the above technical problems, an embodiment of the present application provides a vehicle threshold structure and a vehicle. In this technical solution, the two ends of a main beam member are respectively connected to a first connecting portion and a second connecting portion, so that the main beam member is connected to a threshold body, and then to the floor of the vehicle, and an energy absorbing portion is integrally formed on the main beam member, so that the vehicle threshold structure has the function of absorbing collision force. When installing the vehicle threshold structure, it is only necessary to connect the threshold body to the floor of the vehicle, and there is no need to install other parts such as support plates. The installation process is relatively simple, and the assembly process of the vehicle is simplified while ensuring the function of absorbing collision force, thereby improving the assembly efficiency of the vehicle.

[0049] It should be noted that Figures 1 to 5 The vehicle threshold structure and the simplified schematic diagram of each component in the vehicle are shown. The specific structure of the vehicle threshold structure and other components in the vehicle are not limited to Figures 1 to 5 of examples.

[0050] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0051] Reference Figure 1 , Figure 2 and Figure 3As shown, a vehicle threshold structure provided in an embodiment of the present application is used to be arranged on the side of the vehicle floor 100. It should be noted that the vehicle threshold structure provided in an embodiment of the present application can be applied to various vehicles. It can be arranged on one side of the vehicle floor 100, or multiple vehicle threshold structures can be installed on the side of the vehicle floor 100 as needed, and there is no limit on the number.

[0052] A vehicle rocker structure provided in an embodiment of the present application includes a rocker body 200 and a main beam member 300 .

[0053] The threshold body 200 has a first connection portion 210 and a second connection portion 220 for connecting to the floor 100 . The main beam 300 is located between the first connection portion 210 and the second connection portion 220 . Both ends of the main beam 300 are connected to the first connection portion 210 and the second connection portion 220 , respectively.

[0054] It should be noted that the first connection part 210 and the second connection part 220 are related technologies in this field, and they only need to provide the installation position of the main beam 300. In addition, the connection between the first connection part 210 and the second connection part 220 and the floor 100 is also a related technology in this field. Therefore, the related parts structure of the first connection part 210 and the second connection part 220 is not limited here.

[0055] In addition, the first connection portion 210 and the second connection portion 220 shown in the drawings are only for reference. In possible implementations, the first connection portion 210 and the second connection portion 220 may be replaced with each other.

[0056] The main beam 300 is integrally formed with an energy absorbing portion 310, which is configured to absorb the collision force when the main beam 300 is collided. The main beam 300 is generally horizontally arranged in the longitudinal direction and parallel to the side of the vehicle floor 100, so as to better provide the function of absorbing the collision force.

[0057] In the above embodiment, the two ends of the main beam member 300 are respectively connected to the first connecting portion 210 and the second connecting portion 220, so that the main beam member 300 is connected to the threshold body 200, and then connected to the floor 100 of the vehicle, and an energy absorbing portion 310 is integrally formed on the main beam member 300, so that the threshold structure of the vehicle has the function of absorbing collision force. When installing the threshold structure of the above vehicle, it is only necessary to connect the threshold body 200 to the floor 100 of the vehicle, and there is no need to install other parts such as support plates. The installation process is relatively simple, and the assembly process of the vehicle is simplified while ensuring the function of absorbing collision force, thereby improving the assembly efficiency of the vehicle.

[0058] In a possible implementation manner, a portion of the first connection portion 210 and a portion of the second connection portion 220 are overlapped on the main beam 300 at a side facing away from the floor 100 of the vehicle.

[0059] It can be understood here that part of the first connection part 210 and part of the second connection part 220 are overlapped on the main beam 300 with the side facing away from the floor 100 of the vehicle, which is equivalent to expanding the connection area between the end of the main beam 300 and the first connection part 210 and the second connection part 220, making the connection of the main beam 300 more stable.

[0060] In other possible implementations, at least one of the first connection portion 210 and the second connection portion 220 has a positioning portion 230 , the main beam 300 has a positioning groove 320 , and the positioning portion 230 is inserted into the positioning groove 320 .

[0061] In the above embodiment, when the main beam 300 is installed between the first connection portion 210 and the second connection portion 220 , the positioning portion 230 may be first inserted into the positioning groove 320 to facilitate the positioning of the main beam 300 and improve the connection stability.

[0062] When implementing it, refer to Figure 1 , Figure 3 and Figure 5 As shown, a positioning portion 230 is disposed on both the first connection portion 210 and the second connection portion 220 . The positioning portion 230 is disposed on a side of the first connection portion 210 and the second connection portion 220 away from the floor 100 . The positioning portion 230 is disposed in a long strip shape.

[0063] Furthermore, an inclined surface is provided at the end of the positioning portion 230 to facilitate the positioning portion 230 to be inserted into the positioning groove 320 .

[0064] Alternatively, the positioning portion 230 may be a positioning post, the positioning groove 320 may be a positioning hole, and the positioning post is inserted into the positioning hole, and the specific structure thereof is not limited.

[0065] In a possible implementation manner, the rocker structure of the vehicle further includes at least one reinforcing connector 400 .

[0066] A reinforcing connector 400 is disposed at at least one of the two ends of the main beam 300 . The reinforcing connector 400 covers a surface of the main beam 300 facing away from the sill body 200 and is connected to the first connecting portion 210 or the second connecting portion 220 .

[0067] In the above embodiment, after the end of the main beam 300 is connected to the first connection part 210 and the second connection part 220 , a reinforcement connection part 400 is added.

[0068] It can be understood that the reinforcement connecting member 400 is connected to the main beam member 300 and the first connecting part 210 or the second connecting part 220 at the connecting position between the first connecting part 210 or the second connecting part 220 and the end of the main beam member 300, which further improves the connection stability between the main beam member 300 and the first connecting part 210 or the second connecting part 220.

[0069] In a specific embodiment, at least two of the reinforcement connector 400, the main beam 300 and the first connection part 210 or the second connection part 220 of the corresponding reinforcement connector 400 are welded to each other, and welding has the effects of fast production speed, low cost and high efficiency.

[0070] Specifically, it can be a spot welding method in this field, which is faster and more efficient, does not require open flames, and is less dangerous, and can further improve the installation efficiency of vehicles.

[0071] In one possible implementation, refer to Figure 4 and Figure 5 As shown, the cross section of the main beam member 300 is bent, specifically, in the shape of a bow, so as to sequentially form at least two energy absorbing grooves, and the energy absorbing grooves form an energy absorbing portion 310 .

[0072] Here, the main beam member 300 with a bent cross section is easy to process and simple to manufacture, and the energy absorption groove formed therein can also absorb the collision force.

[0073] It is understandable that the integral main beam member 300 can be integrally formed, and its cross section can be made into a bow shape through relevant technology, which is simple to manufacture and has the function of absorbing energy. Compared with the prior art, the method of installing the support plate in the threshold beam has the effect of saving materials and simplifying the installation process.

[0074] In other possible implementations, three energy absorption grooves are provided, including a first energy absorption groove 500 , a second energy absorption groove 600 , and a third energy absorption groove 700 .

[0075] The notches of the first energy absorbing groove 500 and the third energy absorbing groove 700 face away from the vehicle, and the notch of the second energy absorbing groove 600 faces toward the vehicle.

[0076] The outer side wall of the first energy absorbing groove 500 is used to abut against the floor 100 of the vehicle.

[0077] In the above embodiment, three energy absorption grooves are provided to enhance the effect of absorbing collision force. The outer wall of the first energy absorption groove 500 is used to abut against the floor 100 of the vehicle. It can be understood that when the main beam 300 is subjected to a slight collision, the floor 100 will give the main beam 300 a certain supporting force, further improving the collision resistance of the main beam 300, thereby improving safety.

[0078] In a possible implementation manner, at least one of the first energy absorbing groove 500 , the second energy absorbing groove 600 , and the third energy absorbing groove 700 is used to arrange cables of the vehicle.

[0079] In the above embodiment, the floor 100 of the vehicle has related cables. On the one hand, the arrangement of these cables affects the installation space of other parts on the floor 100. On the other hand, the messy cables may even cause a short circuit in the circuit. At least one of the first energy absorption groove 500, the second energy absorption groove 600 and the third energy absorption groove 700 is used to arrange the cables of the vehicle, which can maximize the utilization of space. At the same time, it also has a certain organization and protection effect on some cables, thereby extending the service life of the cables.

[0080] In a possible implementation manner, at least a portion of the reinforcing connector 400 covers the outer side walls of the positioning portion 230 and the second energy absorbing groove 600 .

[0081] Here, the reinforcing connector 400 has the effect of protecting the connection position between the main beam 300 and the first connector 210 or the second connector 220, which can make the connection position less exposed and reduce air corrosion.

[0082] On the other hand, an embodiment of the present application further provides a vehicle, comprising a vehicle body and a vehicle door sill structure as mentioned in any of the above embodiments and arranged on the vehicle body.

[0083] Among them, the door sill structure of the vehicle has been explained in the above embodiments and will not be repeated here.

[0084] The vehicle provided in the embodiment of the present application is provided with a vehicle threshold structure on the vehicle body, wherein the vehicle threshold structure includes a threshold body 200 and a main beam member 300, wherein the threshold body 200 has a first connection portion 210 and a second connection portion 220 for connecting to a floor 100, the main beam member 300 is located between the first connection portion 210 and the second connection portion 220, and the two ends of the main beam member 300 are respectively connected to the first connection portion 210 and the second connection portion 220, and an energy absorbing portion 310 is integrally formed on the main beam member 300, and the energy absorbing portion 310 is configured to absorb the collision force when the main beam member 300 is collided.

[0085] The two ends of the main beam member 300 are respectively connected to the first connecting portion 210 and the second connecting portion 220, so that the main beam member 300 is connected to the threshold body 200, and then connected to the floor 100 of the vehicle, and an energy absorbing portion 310 is integrally formed on the main beam member 300, so that the threshold structure of the vehicle has the function of absorbing collision force. When installing the threshold structure of the above-mentioned vehicle, it is only necessary to connect the threshold body 200 to the floor 100 of the vehicle, and there is no need to install other parts such as support plates. The installation process is relatively simple, and the assembly process of the vehicle is simplified while ensuring the function of absorbing collision force, thereby improving the assembly efficiency of the vehicle.
