Technical Field

[0001] This application relates to the field of vehicle technology, specifically to vehicle body structure and vehicles. Background Technology

[0002] Currently, with the continuous development of new energy vehicle technology, many vehicles with towing capabilities have emerged on the market to meet people's needs for towing RVs, bicycle racks, and other items. The vehicle includes a body structure, which may include reinforcing structures and crossbeam assemblies.

[0003] In the prior art, a receiving cavity is formed by a crossbeam assembly, and a reinforcing structure is set in the receiving cavity. The reinforcing structure includes a front reinforcing plate, a rear reinforcing plate, and a connecting sleeve. The front and rear reinforcing plates are connected to both ends of the connecting sleeve, and the dragging assembly is connected to the connecting sleeve by a connector.

[0004] However, in the existing technology, the structural strength of the towing component installed at the rear of the vehicle is poor. When towing objects such as RVs and bicycle racks, the rear tow hook is prone to falling off or the components of the vehicle body with the rear tow hook being damaged. Utility Model Content

[0005] The purpose of this application is to provide a vehicle body structure and vehicle to at least address the problem of how to improve the structural strength of the rear tow hook when mounted to the rear of the vehicle body.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: In a first aspect, a vehicle body structure is provided, the vehicle body structure including two rear floor side beams, a crossbeam assembly, a reinforcing structure and a rear tow hook mounting structure, wherein the two rear floor side beams are arranged opposite each other along the width direction of the vehicle; the crossbeam assembly is connected between the two rear floor side beams; the reinforcing structure is disposed between the rear floor side beams and the crossbeam assembly; and the rear tow hook mounting structure is connected to the crossbeam assembly.

[0007] Through the above technical solution, the vehicle body structure provided in this application can enhance the connection strength between the rear floor side beam and the crossbeam assembly by placing the reinforcing structure between them, thereby improving the support strength of the rear floor side beam for the crossbeam assembly. In this way, by connecting the rear tow hook mounting structure to the crossbeam assembly, the crossbeam assembly can have sufficient structural strength, providing better support for the rear tow hook mounting structure when towing other objects, and ensuring the strength requirements of the crossbeam assembly and the rear towing requirements.

[0008] In some embodiments, the rear floor side beam includes a bottom wall portion and two side wall portions connected to the bottom wall portion and arranged along the width direction of the vehicle. Each of the two side wall portions has a first flange portion connected to one end facing the rear of the vehicle. The first flange portion is located on the side of one connected side wall portion that is opposite to the other side wall portion. A crossbeam assembly is connected to the two first flange portions.

[0009] The above technical solution allows for the connection of one end of the two rear floor edge beams and crossbeam assemblies. This connection method is simple in structure and easy to implement.

[0010] In some embodiments, the reinforcing structure includes a first reinforcing plate and a second reinforcing plate connected to each other. The first reinforcing plate is stacked and fixedly connected to the side wall portion, and the second reinforcing plate is stacked and fixedly connected to the first flange portion. A beam assembly is connected to the first flange portion and the second reinforcing plate stacked on the first flange portion.

[0011] The above technical solution can improve the connection strength of the reinforcing structure on the rear floor edge beam. Based on this, by connecting the crossbeam assembly to the first flange and the second reinforcing plate stacked on the first flange, the reinforcing structure and the first flange can jointly support the crossbeam assembly, thereby improving the support strength of the crossbeam assembly and facilitating its support of the rear detachment installation structure.

[0012] In some embodiments, there are two reinforcing structures corresponding to each rear floor edge beam. The first reinforcing plates of the two reinforcing structures are respectively fixed to the two side walls of the rear floor edge beam, and the second reinforcing plates of the two reinforcing structures are respectively fixed to the two first flanges of the rear floor edge beam. The crossbeam assembly is connected to the two first flanges and the two second reinforcing plates respectively stacked on the two first flanges.

[0013] The above technical solution makes the connection between the reinforced structure and the rear floor edge beam and crossbeam assembly more secure, ensuring the strength requirements of the crossbeam assembly and making it easier for users to drag other objects (such as RVs, bicycle racks, etc.).

[0014] In some embodiments, the beam assembly includes a beam body and connecting structures connected to both ends of the beam body. The beam body is connected to two rear floor side beams via two connecting structures, and a rear tow hook mounting structure is connected to the beam body.

[0015] The above technical solution allows the crossbeam assembly to be connected to the two rear floor edge beams respectively. This connection method is simple in structure and easy to implement.

[0016] In some embodiments, the connection structure includes a first connector, a second connector, and a third connector. The first and second connectors are arranged along the length of the beam body and fixed to the beam body. The third connector is connected between the first and second connectors. At least the third connector of the connection structure is connected to the rear floor edge beam.

[0017] The above technical solution can make the connection structure more stable. By connecting the beam assembly to the two rear floor edge beams through at least the third connector of the connection structure, the connection of the beam assembly to the two rear floor edge beams can be more stable, and the structure after connection has higher strength.

[0018] In some embodiments, both the first connector and the second connector include a body portion and a second flange portion connected to the body portion. The body portion is fixed to the crossbeam body, and the second flange portion and the third connector are stacked together. The third connector and the second flange portion of the connection structure are both connected to the rear floor edge beam.

[0019] The above technical solution can improve the structural strength of the first and second connectors, thus providing better support for the third connector and enhancing the structural strength of the first, second, and third connectors after connection, thereby improving the structural strength of the beam assembly and the rear floor edge beam after connection.

[0020] In some embodiments, the rear tow hook mounting structure includes a first mounting member, a second mounting member, and a third mounting member. The first and second mounting members are arranged along the length of the crossbeam body and fixed to the crossbeam body. The third mounting member is connected between the first and second mounting members. The third mounting member of the rear tow hook mounting structure is adapted to connect to a rear tow hook.

[0021] The above technical solution facilitates the installation of the rear tow hook mounting structure on the crossbeam assembly and ensures the structural strength after the connection between the rear tow hook mounting structure and the crossbeam assembly. The rear tow hook of the third mounting component connects the towed RV, bicycle rack, and other items to the crossbeam assembly, meeting users' outdoor needs for towing RVs, bicycle racks, etc.

[0022] In some embodiments, the third mounting member includes a mounting plate and a mounting cylinder connected to the mounting plate. The mounting plate is connected between the first mounting member and the second mounting member, and the mounting cylinder is connected to the side of the mounting plate opposite to the first and second mounting members. The mounting cylinder is adapted to connect to a rear trailer hitch.

[0023] Through the above technical solution, the rear tow hook can connect the towed caravan, bicycle rack and crossbeam assembly, and the crossbeam assembly can be connected to the rear floor side beam through the reinforcement structure, so as to meet the outdoor needs of users to tow caravan, bicycle rack and so on.

[0024] Secondly, a vehicle is also provided, which includes the body structure described in any of the above technical solutions. Since the vehicle provided in this application includes the body structure described in any of the above embodiments, both can solve the same technical problem and achieve the same effect.

[0025] The beneficial effects of this application are: (1) Through the above technical solution, the vehicle body structure provided in this application can strengthen the connection strength between the rear floor side beam and the cross beam assembly by setting the reinforcing structure between the rear floor side beam and the cross beam assembly, thereby improving the support strength of the rear floor side beam to the cross beam assembly. In this way, the rear tow hook mounting structure can be connected to the cross beam assembly, so that the cross beam assembly has sufficient structural strength and can provide better support for the rear tow hook mounting structure when dragging other objects through the rear tow hook mounting structure, ensuring the strength requirements of the cross beam assembly and the rear towing requirements.

[0026] (2) By connecting the crossbeam assembly to the two first flanges, the two rear floor edge beams and one end of the crossbeam assembly can be connected. This connection method is simple in structure and easy to implement.

[0027] (3) By stacking and fixing the first reinforcing plate to the side wall portion, and stacking and fixing the second reinforcing plate to the first flange portion, the connection strength of the reinforcing structure on the rear floor edge beam can be improved. On this basis, by connecting the crossbeam assembly to the first flange portion and the second reinforcing plate stacked on the first flange portion, the crossbeam assembly can be supported by the reinforcing structure and the first flange portion together, thereby improving the support strength of the crossbeam assembly and facilitating the crossbeam assembly to support the rear unhooked installation structure.

[0028] (4) By connecting the crossbeam assembly to the two first flanges and the two second reinforcing plates stacked on the two first flanges respectively, the connection between the reinforcing structure and the rear floor edge beam and the crossbeam assembly can be made more secure, ensuring the strength requirements of the crossbeam assembly and making it convenient for users to drag other objects (such as RVs, bicycle racks, etc.).

[0029] (5) By connecting the beam body to the two rear floor edge beams through two connecting structures, the beam assembly can be connected to the two rear floor edge beams respectively. This connection method is simple in structure and easy to implement.

[0030] (6) By arranging the first and second connectors along the length of the beam body and fixing them to the beam body, and connecting the third connector between the first and second connectors, the connection structure can form a more stable structure by connecting the at least third connector of the connection structure to the rear floor edge beam. In this way, the beam assembly can be more stably connected to the two rear floor edge beams by connecting the at least third connector of the connection structure to the rear floor edge beam, and the structure after connection has higher strength.

[0031] (7) By fixing the main body to the crossbeam body, and stacking the second flange and the third connector, the third connector and the second flange of the connection structure are both connected to the rear floor edge beam, which can make the structural strength of the first connector and the second connector higher. This can provide better support for the connection of the third connector, improve the structural strength of the first connector, the second connector and the third connector after connection, and thus improve the structural strength of the crossbeam assembly after connection with the rear floor edge beam.

[0032] (8) By arranging and fixing the first and second mounting parts along the length of the crossbeam body, and connecting the third mounting part between the first and second mounting parts, the third mounting part of the rear tow hook mounting structure is suitable for connecting the rear tow hook, which facilitates the installation of the rear tow hook mounting structure on the crossbeam assembly and ensures the structural strength after the rear tow hook mounting structure is connected to the crossbeam assembly.

[0038] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0039] This application provides a vehicle that can be a pure gasoline vehicle, a pure electric vehicle, a hybrid vehicle, etc. The vehicle can also be a sedan, SUV, MPV, sports car, racing car, truck, engineering vehicle, special vehicle, etc.

[0040] Please see Figure 1 and Figure 2The vehicle may include a body structure 10, which may include a body body and two rear floor side beams 1 disposed on the body body. The two rear floor side beams 1 are along the width direction of the vehicle (e.g., Figure 2 The components are arranged in opposite directions (A) to enhance the structural strength of the vehicle body. For example, the vehicle body includes a rear floor located under the vehicle's trunk, and two rear floor side beams 1 can be connected to the rear floor to enhance its structural strength.

[0041] In some embodiments, the vehicle body structure 10 may be a monocoque vehicle body structure or a non-monocoque vehicle body structure. This application is exemplified by using a non-monocoque vehicle body structure 10 as an example.

[0042] In some other embodiments, the vehicle body structure 10 and the rear floor side beam 1 can be connected by welding. In other examples, the vehicle body structure 10 and the rear floor side beam 1 can also be connected by snap-fitting, riveting, fasteners, etc. This application does not make specific limitations on this.

[0043] In some embodiments, please refer to Figure 1 and Figure 2 The vehicle body structure 10 may also include a crossbeam assembly 2, a reinforcing structure 3, and a rear tow hook mounting structure 4. The crossbeam assembly 2 is connected between two rear floor side beams 1; the reinforcing structure 3 is located between the rear floor side beams 1 and the crossbeam assembly 2; and the rear tow hook mounting structure 4 is connected to the crossbeam assembly 2.

[0044] In this way, by placing the reinforcing structure 3 between the rear floor edge beam 1 and the crossbeam assembly 2, the connection strength between the rear floor edge beam 1 and the crossbeam assembly 2 can be strengthened, thereby improving the support strength of the rear floor edge beam 1 for the crossbeam assembly 2. Thus, by connecting the rear tow hook mounting structure 4 to the crossbeam assembly 2, the crossbeam assembly 2 can have sufficient structural strength, providing better support for the rear tow hook mounting structure 4 when dragging other objects, ensuring the strength requirements of the crossbeam assembly 2 and the rear dragging requirements.

[0045] In some embodiments, the rear floor side beam 1 includes a bottom wall portion 11 and two side wall portions 12 connected to the bottom wall portion 11 and arranged along the width direction of the vehicle. The ends of the two side wall portions 12 facing the rear of the vehicle are each connected to a first flange portion 13. The first flange portion 13 is located on the side of the connected side wall portion 12 that is opposite to the other side wall portion 12. The crossbeam assembly 2 is connected to the two first flange portions 13.

[0046] In this way, the two rear floor edge beams 1 and one end of the crossbeam assembly 2 can be connected through the two first flanges 13. This connection method is simple in structure and easy to implement.

[0047] In some examples, the rear floor edge beam 1 and the crossbeam assembly 2 can be connected by welding, snap-fitting, riveting, or other methods.

[0048] In some other embodiments, the cross-section of the rear floor edge beam 1 can be a U-shaped structure, or it can be an L-shaped structure, etc. The cross-section of the rear floor edge beam 1 is perpendicular to its length.

[0049] In some examples, the two rear floor edge beams 1 may have the same structure; in other examples, the two rear floor edge beams 1 may have different structures. This application provides an exemplary description using the example of two rear floor edge beams 1 having the same structure.

[0050] In some embodiments, the reinforcing structure 3 includes a first reinforcing plate 31 and a second reinforcing plate 32 connected to each other. The first reinforcing plate 31 is stacked and fixedly connected to the side wall portion 12, and the second reinforcing plate 32 is stacked and fixedly connected to the first flange portion 13. The crossbeam assembly 2 is connected to the first flange portion 13 and the second reinforcing plate 32 stacked on the first flange portion 13. The first reinforcing plate 31 and the second reinforcing plate 32 have the same structure.

[0051] In this way, by stacking and fixing the first reinforcing plate 31 to the side wall portion 12, and stacking and fixing the second reinforcing plate 32 to the first flange portion 13, the connection strength of the reinforcing structure 3 on the rear floor side beam can be improved. On this basis, by connecting the crossbeam assembly 2 to the first flange portion 13 and stacking the second reinforcing plate 32 on the first flange portion 13, the reinforcing structure 3 and the first flange portion 13 can jointly support the crossbeam assembly 2, thereby improving the support strength of the crossbeam assembly 2 and facilitating the crossbeam assembly 2 to support the rear unhooked installation structure.

[0052] In some examples, the first reinforcing plate 31 is provided with multiple sets of through holes 311, which are arranged along the length of the vehicle, such as ( Figure 2 In the direction B), the through holes 311 in each group are arranged along the height direction of the vehicle. The first reinforcing plate 31 can be bolted through the through holes 311 to connect with the side wall portion 12 of the rear floor side beam 1. This connection method is simple and facilitates the assembly of the first reinforcing plate 31 and the side wall portion 12 of the rear floor side beam 1, so that the rear floor side beam 1 and the reinforcing structure 3 are completely fitted together at one end along the width direction of the vehicle.

[0053] For example, the number of multiple sets of through holes 311 can be 2, or the number of multiple sets of through holes 311 can be other than 2, such as 3, 4, 5, etc. This application does not make a specific limitation in this regard.

[0054] In some other examples, the first reinforcing plate 31 and the side wall portion 12 can also be connected by snap-fitting, welding, or other methods.

[0055] In some examples, both the second reinforcing plate 32 and the first flange 13 are provided with connection holes 321, through which fasteners such as bolts can be inserted and connected to the crossbeam assembly 2, so as to realize the connection between the crossbeam assembly 2 and the reinforcing structure 3, and between the crossbeam assembly 2 and the rear floor side beam 1.

[0056] In other examples, the second reinforcing plate 32, the first flange 13, and the crossbeam assembly 2 can be connected by welding, snap-fitting, or other methods.

[0057] In some embodiments, the first reinforcing plate 31 and the second reinforcing plate 32 can be an integral structure, for example, the overall structure can be an L-shaped structure.

[0058] In some embodiments, the number of reinforcing structures 3 can be multiple, and the multiple reinforcing structures 3 are arranged along the width direction of the vehicle, so that the connection between the reinforcing structure 3 and the rear floor side beam 1 and the crossbeam assembly 2 can be more stable.

[0059] In some examples, there may be two reinforcing structures 3, with each rear floor edge beam 1 connected to two reinforcing structures 3.

[0060] In some embodiments, please refer to Figure 2 and Figure 3 , Figure 3 for Figure 1 The schematic diagram of a portion of the vehicle body structure 10 shown shows that there are two reinforcing structures 3 corresponding to each rear floor side beam 1. The first reinforcing plates 31 of the two reinforcing structures 3 are respectively fixed to the two side wall portions 12 of the rear floor side beam 1, and the second reinforcing plates 32 of the two reinforcing structures 3 are respectively fixed to the two first flange portions 13 of the rear floor side beam 1. The crossbeam assembly 2 is connected to the two first flange portions 13 and the two second reinforcing plates 32 respectively stacked on the two first flange portions 13.

[0061] In this way, by connecting the crossbeam assembly 2 to the two first flanges 13 and the two second reinforcing plates 32 respectively stacked on the two first flanges 13, the connection between the reinforcing structure 3 and the rear floor edge beam 1 and the crossbeam assembly 2 can be made more secure, ensuring the strength requirements of the crossbeam assembly 2 and making it convenient for users to drag other objects (such as RVs, bicycle racks, etc.).

[0062] In some embodiments, please refer to Figures 1 to 4 , Figure 4 for Figure 1The diagram shows the cooperation relationship between the crossbeam assembly 2 and the rear tow hook mounting structure 4 in the vehicle body structure 10. The crossbeam assembly 2 includes a crossbeam body 21 and connecting structures 22 connected to both ends of the crossbeam body 21. The crossbeam body 21 is connected to two rear floor side beams 1 through two connecting structures 22. The rear tow hook mounting structure 4 is connected to the crossbeam body 21.

[0063] In this way, the crossbeam assembly 2 can be connected to the two rear floor side beams 1 respectively through the connection structure 22 at both ends of the crossbeam body 21. This connection method is simple in structure and easy to implement.

[0064] In some examples, the connection structures 22 at both ends of the beam body 21 can be the same, while in other examples, the connection structures 22 at both ends of the beam body 21 can be different.

[0065] This application uses the example of identical connection structures 22 at both ends of the beam body 21 as an example for illustrative purposes.

[0066] In some embodiments, the connecting structure 22 includes a first connector 221, a second connector 222, and a third connector 223. The first connector 221 and the second connector 222 are arranged along the length direction of the crossbeam body 21 and fixed to the crossbeam body 21. The third connector 223 is connected between the first connector 221 and the second connector 222. At least the third connector 223 of the connecting structure 22 is connected to the rear floor side beam 1. That is, the third connector 223 can be connected to the rear floor side beam 1, or the first connector 221, the second connector 222, and the third connector 223 can all be connected to the rear floor side beam 1. The length direction of the crossbeam body 21 is consistent with the width direction of the vehicle.

[0067] In this way, by connecting the third connector 223 between the first connector 221 and the second connector 222, the connection structure 22 can form a more stable structure. Thus, by connecting the connection structure 22 to the rear floor side beam 1 through at least the third connector 223, the connection between the beam assembly 2 and the two rear floor side beams 1 can be more stable, and the structure after connection has higher strength.

[0068] In some examples, the first connector 221, the second connector 222, and the third connector 223 can be an integral structure, for example, manufactured by bending, stamping, or other processes. In other examples, the first connector 221, the second connector 222, and the third connector 223 can be separate structures. For example, the first connector 221, the second connector 222, and the third connector 223 can be connected by welding, or they can also be connected by snap-fitting, riveting, or other methods.

[0069] In some embodiments, the first connector 221 and the second connector 222 each include a body portion 2211 and a second flange portion 2212 connected to the body portion 2211. The body portion 2211 is fixed to the crossbeam body 21. The second flange portion 2212 and the third connector 223 are stacked. The third connector 223 and the second flange portion 2212 of the connecting structure 22 are both connected to the rear floor edge beam 1.

[0070] The body portion 2211 includes a first body portion 2211A and a second body portion 2211B, and the second flange portion 2212 includes a third flange portion 2212A and a fourth flange portion 2212B. The first body portion 2211A and the third flange portion 2212A are connected to form a first connector 221, and the second body portion 2211B and the fourth flange portion 2212B are connected to form a second connector 222.

[0071] In this way, by setting the second flange 2212, the structural strength of the first connector 221 and the second connector 222 can be increased, which can better support the connection of the third connector 223, improve the structural strength of the first connector 221, the second connector 222 and the third connector 223 after connection, and thus improve the structural strength of the connection between the crossbeam assembly 2 and the rear floor edge beam 1.

[0072] In some examples, the bodies of the first connector 221 and the second connector 222 and the crossbeam body 21 can be connected by welding, such as CO2 shielded welding, to ensure the flatness requirements with the rear floor edge beam 1.

[0073] In some other embodiments, the first connector 221 and the second connector 222 can be directly connected to the rear floor edge beam 1.

[0074] In some embodiments, the rear tow hook mounting structure 4 includes a first mounting member 41, a second mounting member 42, and a third mounting member 43. The first mounting member 41 and the second mounting member 42 are arranged along the length direction of the crossbeam body 21 and fixed to the crossbeam body 21. The third mounting member 43 is connected between the first mounting member 41 and the second mounting member 42. The third mounting member 43 of the rear tow hook mounting structure 4 is adapted to connect to the rear tow hook.

[0075] In this way, the cooperation of the first mounting component 41, the second mounting component 42, and the third mounting component 43 facilitates the installation of the rear tow hook mounting structure 4 on the crossbeam assembly 2, and ensures the structural strength after the connection between the rear tow hook mounting structure 4 and the crossbeam assembly 2. The rear tow hook of the third mounting component 43 can connect towed caravans, bicycle racks, and the crossbeam assembly 2, meeting the outdoor needs of users towing caravans, bicycle racks, etc.

[0076] In some examples, the first mounting component 41, the second mounting component 42, and the beam body 21 can be connected by welding, such as CO2 shielded welding. By performing segmented welding of the first mounting component 41, the second mounting component 42, and the beam body 21 using CO2 shielded welding, the welding thermal deformation of the first mounting component 41, the second mounting component 42, and the beam body 21 can be reduced.

[0077] In some examples, the third mounting part 43 can be connected to the second mounting part 42 and the first mounting part 41 using fasteners such as bolts. In other examples, the third mounting part 43 can be connected to the second mounting part 42 and the first mounting part 41 by welding, snap-fitting, riveting, or other methods.

[0078] In some embodiments, the third mounting member 43 includes a mounting plate 431 and a mounting cylinder 432 connected to the mounting plate 431. The mounting plate 431 is connected between the first mounting member 41 and the second mounting member 42, and the mounting cylinder 432 is connected to the side of the mounting plate 431 opposite to the first mounting member 41 and the second mounting member 42. The mounting cylinder 432 is adapted to connect to a rear trailer hitch.

[0079] In this way, by connecting the mounting cylinder 432 to the side of the mounting plate 431 opposite to the first mounting member 41 and the second mounting member 42, the mounting cylinder 432 is suitable for connecting the rear tow hook. The rear tow hook can connect the towed caravan, bicycle rack and crossbeam assembly 2. The crossbeam assembly 2 and the rear floor side beam 1 are connected by the reinforcing structure 3, which meets the outdoor needs of users to tow caravans, bicycle racks and the like.

[0080] In some examples, the mounting cylinder 432 has a first through hole 4321 on the right end face along the length of the crossbeam body 21, and a second through hole 4322 on the upper end face along the length of the crossbeam body 21. In this way, the rear trailer hook and the mounting cylinder 432 can be positioned by a positioning pin through the first through hole 4321, and then the rear trailer hook and the mounting cylinder 432 can be fastened by bolts through the second through hole 4322, which meets the outdoor needs of users to tow RVs, bicycle racks, etc.

[0081] In some other embodiments, the mounting cylinder 432 can be connected to the RV or bicycle frame by means of snap-fit, hook connection or other methods.

[0082] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
