However, the traditional frame-shaped front-end frame is heavily dependent on the manufacturing accuracy of the cabin side beam. Summary of the Invention

[0003] The embodiments of the present application provide a front-end structure and a vehicle, aiming to solve the problem of how to improve the assembly accuracy of the front face of the vehicle without relying on the manufacturing accuracy of the cabin side beams.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] In the first aspect, an embodiment of the present application provides a front-end structure, which is applied to a vehicle.

The upper side beam is connected to the front mounting end plate via the adjustment component, and the position of the upper side beam can be adjusted relative to the front mounting end plate via the adjustment component.

[0006] Based on the front-end structure of the embodiment of the present application, the upper side beam can adjust its position in various directions relative to the front mounting end plate through the adjustment component, that is, the front-end structure can automatically adjust the position of important front appearance parts of the car such as the front hood lock, headlights, front bumper, etc. installed on the upper side beam, thereby improving the assembly accuracy of the front face of the vehicle, and reducing or eliminating the need to rely on the manufacturing accuracy of the cabin side beam.

[0007] In some embodiments of the present application, the adjustment assembly includes an adjustment bracket; one of the adjustment bracket and the front mounting end plate has a first adjustment hole, and the other is connected to a first adjustment member, the first adjustment member is partially located in the first adjustment hole, and can move along the length direction and the height direction of the vehicle in the first adjustment hole; one of the adjustment bracket and the upper side beam has a second adjustment hole, and the other is connected to a second adjustment member, the second adjustment member is partially located in the second adjustment hole, and can move along the width of the vehicle in the second adjustment hole.

[0008] Based on the above embodiment, one of the adjustment bracket and the front mounting end plate has a first adjustment hole, and the other is connected to a first adjustment member. When the first adjustment member moves in the first adjustment hole along the length direction and the height direction of the vehicle, the adjustment bracket also moves relative to the front mounting end plate in the length direction and the height direction of the vehicle, thereby driving the upper side beam connected to the adjustment bracket to move relative to the front mounting end plate in the length direction and the height direction of the vehicle, thereby realizing position adjustment of the upper side beam in the length direction and the height direction of the vehicle.

[0009] Similarly, one of the adjustment bracket and the upper side beam has a second adjustment hole, and the other is connected to a second adjustment member. The second adjustment member moves along the width direction of the vehicle in the second adjustment hole, and the upper side beam moves along the width direction of the vehicle relative to the front mounting end plate, thereby realizing the position adjustment of the upper side beam in the width direction of the vehicle.

[0010] In some embodiments of the present application, the first adjusting member includes a first fastener and a first adjusting rod, one end of the first adjusting rod is connected to the adjusting bracket or the front mounting end plate, and the other end passes through the first adjusting hole and is fixedly connected to the first fastener, and the aperture of the first adjusting hole is larger than the outer diameter of the first adjusting rod; the second adjusting member includes a second fastener and a second adjusting rod, one end of the second adjusting rod is connected to the adjusting bracket or the upper side beam, and the other end passes through the second adjusting hole and is fixedly connected to the second fastener, and the aperture of the second adjusting hole is larger than the outer diameter of the second adjusting rod.

[0011] Based on the above embodiment, the first adjustment rod moves in the first adjustment hole along the length direction of the vehicle and / or the height direction of the vehicle, so that the adjustment bracket can move relative to the front mounting end plate in the length direction of the vehicle and / or the height direction of the vehicle, and the first fastener can limit the first adjustment rod from falling out of the first adjustment hole.

[0012] Similarly, the second adjusting rod moves along the width direction of the vehicle in the second adjusting hole, so that the upper side rail can move in the width direction of the vehicle relative to the front mounting end plate, and the second fastener can limit the second adjusting rod from falling out of the second adjusting hole.

[0013] In some embodiments of the present application, the difference between the aperture of the first adjustment hole and the outer diameter of the first adjustment rod is m, 0mm<m≤7mm; the difference between the aperture of the second adjustment hole and the outer diameter of the second adjustment rod is n, 0mm<n≤7mm.

[0014] Based on the above embodiment, within this range, the upper side beam has sufficient adjustment space in the length direction, width direction and height direction of the vehicle, so that important front appearance parts of the car such as the front hood lock, headlights, front bumper, etc. installed on the upper side beam have sufficient adjustment space when the vehicle is assembled.

[0015] In some embodiments of the present application, the front end structure also includes a front collision beam assembly and a first connecting member, wherein the front collision beam assembly is installed on the front mounting end plate; one end of the first connecting member is connected to the upper side beam, and the other end is connected to the front collision beam assembly.

[0016] Based on the above embodiment, the first connecting member can simultaneously enhance the rigidity and stability of the front impact beam assembly and the roof side rail.

[0017] In some embodiments of the present application, along the width direction of the vehicle, the first connecting member is connected to the center position of the front collision beam assembly, and the first connecting member is connected to the center position of the roof side rail.

[0018] Based on the above embodiment, both ends of the upper side beam are connected to the adjustment bracket. After the first connecting member is connected to the middle position of the upper side beam, the first connecting member reinforces the structure of the center position of the upper side beam, further improving the structural strength of the upper side beam.

[0019] In some embodiments of the present application, the front-end structure also includes a calf protection assembly, which includes a protective beam and a first energy absorption box. The protective beam is located in front of the front mounting end plate along the length direction of the vehicle; the first energy absorption box is connected between the protective beam box and the front mounting end plate.

[0020] Based on the above embodiment, the first energy absorption box is located between the protective crossbeam and the front mounting end plate. When a pedestrian collides with the protective crossbeam, both the protective crossbeam and the first energy absorption box can absorb and disperse part of the impact force generated by the collision, thereby reducing damage to the pedestrian and the vehicle. In some embodiments of the present application, the front end structure further includes a second connector, one end of which is connected to the lower leg protection assembly and the other end is connected to the front collision crossbeam assembly.

[0021] Based on the above embodiment, after the second connecting member connects the front impact beam assembly and the lower leg protection assembly, the rigidity and stability of the front impact beam assembly and the lower leg protection assembly are enhanced.

[0022] In some embodiments of the present application, the front end structure further includes a radiator support assembly, and the radiator support assembly is installed on the first energy absorption box.

[0023] Based on the above embodiment, the radiator support assembly is installed on the first energy absorption box. The vibration generated by the radiator during the driving of the vehicle can be transmitted to the first energy absorption box. The first energy absorption box can absorb part of the kinetic energy transmitted from the radiator to the radiator support assembly, thereby reducing the vibration generated by the radiator and protecting the radiator.

[0024] In some embodiments of the present application, the radiator bracket assembly includes a first bracket and a second bracket connected to each other, the first bracket and the second bracket enclose a cavity, the first bracket and the second bracket are both connected to the first energy absorption box, and the second bracket is used to connect to the radiator.

[0025] Based on the above embodiment, since the first bracket and the second bracket form a cavity, after the external force of the radiator is transmitted to the first bracket and the second bracket, the first bracket and / or the second bracket can be deformed toward the cavity to absorb the external force transmitted from the radiator to the first bracket and the second bracket, thereby protecting the radiator.

[0026] In a second aspect, an embodiment of the present application provides a vehicle, comprising a side beam structure and a front end structure as described above, wherein the side beam structure is arranged along the length direction of the vehicle body; and the front mounting end plate is mounted at the front end of the side beam structure along the length direction of the vehicle.

[0027] Based on the vehicle of the embodiment of the present application, since it has the above-mentioned front-end structure, the upper side beam of the front-end structure is adjustable relative to the front mounting end plate, and the position of the vehicle front face appearance parts installed to the upper side beam is adjustable relative to the front mounting end plate, thereby ensuring the assembly accuracy and aesthetics of the vehicle front face, and reducing or eliminating the need to rely on the manufacturing accuracy of the cabin side beams. Therefore, the vehicle reduces the requirements for the manufacturing accuracy of the side beams, thereby reducing the manufacturing requirements of the vehicle.

[0028] In some embodiments of the present application, the side beam structure includes two side beams, two side beam front end plates and a front wall plate. The side beam front end plates are installed on the side beams and fixedly connected to the front end structure. The side beams are arranged along the length direction of the vehicle, and the two side beams are arranged along the width direction of the vehicle. The front wall plate connects the two side beams.

[0029] Based on the above embodiment, the front wall panel is connected to the two side beams, which enhances the structural strength of the side beam structure. That is, the side beam structure has a stronger structural strength, and the side beam structure can better support the front end structure.

[0040] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0041] In the relevant technical field, the front end structure of the vehicle body includes a frame-shaped front end frame, which is installed on the front end plate of the cabin side beam. The front end frame integrates multiple installation functions. For example, the upper side beam of the front end frame integrates the installation points of important front appearance parts of the car, such as the front hood lock, headlights, and front bumper, which plays a decisive role in the assembly accuracy of the front face of the vehicle. However, the traditional frame-shaped front end frame is heavily dependent on the control level of the welding accuracy of the side beam assembly. For example, if a welding error occurs in the side beam assembly during the welding process, the position of the front end frame connected to the side beam assembly will change, and then the installation position of important front appearance parts of the car, such as the front hood lamps, headlights, and front bumper installed on the upper side beam of the front end frame will deviate.

[0042] In order to solve the above technical problems, the present application proposes a vehicle, which is used to solve the problem that the assembly accuracy of the front face of the vehicle depends on the manufacturing accuracy of the side beam 21.

[0043] It should be noted that the vehicle provided in the embodiment of the present application can be a fuel vehicle, a new energy vehicle, or any other power-driven vehicle. Generally, all types of vehicles have a front-end structure 10, and the specific one can be selected according to actual conditions. This application does not make any specific restrictions on this.

[0044] Please refer to Figure 1 As shown, in some embodiments of the present application, the vehicle includes a side beam structure 20 and a front end structure 10, the side beam structure 20 is arranged along the length direction of the vehicle body; the front end structure 10 is installed at the front end of the side beam structure 20 along the length direction of the vehicle.

[0045] Among them, the side beam structure 20 is used to constitute the vehicle's cabin assembly to protect the vehicle's engine. It can be understood that the number of the side beam structures 20 is two, and the two side beam structures 20 are arranged opposite to each other along the width direction of the vehicle.

[0046] Please refer to Figure 1 As shown, the side beam structure 20 includes a side beam 21 and a side beam front end plate 22 . The side beam 21 is arranged along the length direction of the vehicle; the side beam front end plate 22 is installed on the side beam 21 and fixedly connected to the front end structure 10 .

[0047] In some embodiments of the present application, the side beam structure 20 further includes a front wall panel 23 arranged along the width direction of the vehicle, and both ends of the front wall panel 23 are respectively connected to the two side beams 21 to enhance the structural strength of the side beam structure 20 .

[0048] The main functions of the front end structure 10 include protecting the engine and surrounding components, supporting the front face of the vehicle, and protecting the driver and pedestrians in the event of a collision. Figure 1 As shown, in some embodiments of the present application, the front end structure 10 includes a front mounting end plate 11, an adjustment assembly 12, and an upper side rail 13. The upper side rail 13 is connected to the front mounting end plate 11 via the adjustment assembly 12, and the position of the upper side rail 13 is adjustable relative to the front mounting end plate 11 via the adjustment assembly 12. The front mounting end plate 11 is connected to the side rail front end plate 22 of the side rail structure 20.

[0049] The front mounting end plate 11 is used to realize the connection between the front end structure 10 and the side beam structure 20, and is used to support the remaining parts in the front end structure 10. In the embodiment of the present application, there is no limitation on the structure, shape and material of the front mounting end plate 11. The front mounting end plate 11 can adopt a self-welding process to ensure its own strength and reduce the difficulty of stamping.

[0050] The roof rail 13 is used to mount important front exterior components of the vehicle, such as the headlights, headlights, and front bumper. It is understood that the roof rail 13 is arranged along the width of the vehicle. Therefore, each end of the roof rail 13 is connected to the front mounting end plate 11 via a corresponding adjustment assembly 12. When the roof rail 13 moves relative to the front mounting end plate 11, the two adjustment assemblies 12 must operate simultaneously. Furthermore, the roof rail 13 can be made of a variety of materials and processes, such as stamped sheet metal, plastic, and aluminum alloy die-casting, depending on different needs.

[0051] Based on the front end structure 10 of the embodiment of the present application, the upper side beam 13 can adjust its position relative to the front mounting end plate 11 via the adjustment component 12, that is, the front end structure 10 can automatically adjust the positions of important front appearance parts of the car such as the front hood lock, headlights, front bumper, etc. installed on the upper side beam 13, thereby improving the front face accuracy and aesthetics of the vehicle without relying on the manufacturing accuracy of the cabin side beam 21.

[0052] The adjustment component 12 is used to adjust the position of the upper side rail 13 relative to the front mounting end plate 11. Figure 1 As shown, in some embodiments of the present application, the adjustment assembly 12 includes an adjustment bracket 121; one of the adjustment bracket 121 and the front mounting end plate 11 has a first adjustment hole, and the other is connected to a first adjustment member 122, and the first adjustment member 122 is partially located in the first adjustment hole and can move along the length direction and height direction of the vehicle within the first adjustment hole;

[0053] One of the adjustment bracket 121 and the roof rail 13 has a second adjustment hole, and the other is connected to a second adjustment member 123 . The second adjustment member 123 is partially located in the second adjustment hole and can move along the width of the vehicle in the second adjustment hole.

[0054] When the first adjustment member 122 moves in the first adjustment hole along the length direction and the height direction of the vehicle, the adjustment bracket 121 also moves in the length direction and the height direction of the vehicle relative to the front mounting end plate 11, thereby driving the upper side beam 13 connected to the adjustment bracket 121 to move in the length direction and the height direction of the vehicle relative to the front mounting end plate 11, thereby realizing position adjustment of the upper side beam 13 in the length direction and the height direction of the vehicle, and further realizing position adjustment of the front face parts of the vehicle installed on the upper side beam 13 in the length direction and the height direction of the vehicle.

[0055] Similarly, when the second adjusting member 123 moves in the second adjusting hole along the width direction of the vehicle, the upper side beam 13 moves in the width direction of the vehicle relative to the front mounting end plate 11, thereby realizing position adjustment of the upper side beam 13 in the width direction of the vehicle, and further realizing position adjustment of the vehicle front face parts installed on the upper side beam 13 in the width direction of the vehicle.

[0056] In a specific embodiment of the present application, the front mounting end plate 11 has a first adjustment hole, and the adjustment bracket 121 is connected to the first adjustment member 122 ; the upper side beam 13 has a second adjustment hole, and the adjustment bracket 121 is connected to the first adjustment member 122 .

[0057] Specifically, it can be understood that the adjustment bracket 121 splits the upper side beam 13 relative to the front mounting end plate 11 along the length direction of the vehicle, the height direction of the vehicle and the width direction of the vehicle, and realizes the movement of the upper side beam 13 relative to the front mounting end plate 11 along the length direction of the vehicle and the height direction of the vehicle between the adjustment bracket 121 and the front mounting end plate 11, and realizes the movement of the upper side beam 13 relative to the front mounting end plate 11 along the width direction of the vehicle between the adjustment bracket 121 and the upper side beam 13.

[0058] Of course, it is understandable that the adjustment bracket 121 can be split differently to move the roof rail 13 relative to the front mounting end plate 11 along the length direction of the vehicle, the height direction of the vehicle, and the width direction of the vehicle, and the movement of the roof rail 13 relative to the front mounting end plate 11 along the length direction of the vehicle, the height direction of the vehicle, and the width direction of the vehicle can still be achieved, for example:

[0059] In some embodiments of the present application, the adjusting assembly 12 comprises an adjusting bracket 121; one of the adjusting bracket 121 and the front mounting end plate 11 has a first adjusting hole, and the other is connected with a first adjusting member 122, which is partially located in the first adjusting hole and is movable in the first adjusting hole along the length direction of the vehicle.

[0060] In some embodiments of the present application, the adjusting assembly 12 comprises an adjusting bracket 121; one of the adjusting bracket 121 and the front mounting end plate 11 has a first adjusting hole, and the other is connected with a first adjusting member 122, which is partially located in the first adjusting hole and is movable in the first adjusting hole along the length direction of the vehicle.

[0061] In some embodiments of the present application, the first adjusting member 122 comprises a first fastener and a first adjusting rod, one end of the first adjusting rod is fixedly connected with the adjusting bracket 121 or the front mounting end plate 11, and the other end passes through the first adjusting hole and is fixedly connected with the first fastener, the diameter of the first adjusting hole is larger than the outer diameter of the first adjusting rod.

[0062] The first adjusting member 122 can simultaneously realize the position adjustment of the adjusting bracket 121 relative to the front mounting end plate 11 along the length direction and the height direction of the vehicle, and can also realize the fixed connection of the adjusting bracket 121 and the front mounting end plate 11 after the position adjustment is completed.

[0063] In some embodiments of the present application, the second adjusting member 123 comprises a second fastener and a second adjusting rod, one end of the second adjusting rod is fixedly connected with the adjusting bracket 121 or the upper side beam 13, and the other end passes through the second adjusting hole and is fixedly connected with the second fastener, the diameter of the second adjusting hole is larger than the outer diameter of the second adjusting rod.

[0064] Similarly, the second adjusting member 123 can simultaneously realize the position adjustment of the adjusting bracket 121 relative to the front mounting end plate 11 along the width direction of the vehicle, and can also realize the fixed connection of the adjusting bracket 121 and the upper side beam after the position adjustment is completed.

[0065] In order to further simplify the structure of the front-end structure 10, in some embodiments of the present application, the first adjusting member 122 and the second adjusting member 123 can both be configured as bolts, that is, the first adjusting rod and the second adjusting rod can both be configured as screws, and the first fastener and the second fastener can both be configured as nuts. Before tightening, the screw and the nut can move in the first adjustment hole or the second adjustment hole. After tightening, the screw and the nut can realize the connection between the front mounting end plate 11 and the adjustment bracket 121, the adjustment bracket 121 and the upper side beam 13.

[0066] Of course, it is understandable that a separate connecting member 16 can also be provided to realize the connection between the front mounting end plate 11 and the adjustment bracket 121, and the adjustment bracket 121 and the upper side beam 13. For example, after the position adjustment of the upper side beam 13 is completed, the front mounting end plate 11 and the adjustment bracket 121 are connected, and the adjustment bracket 121 and the upper side beam 13 are connected by bolts, rivets, etc.

[0067] In some embodiments of the present application, the difference between the diameter of the first adjustment hole and the outer diameter of the first adjustment rod is m, where 0mm < m ≤ 7mm; the difference between the diameter of the second adjustment hole and the outer diameter of the second adjustment rod is n, where 0mm < n ≤ 7mm. In the embodiments of the present application, the diameters of the first adjustment hole and the second adjustment hole are equivalent diameters. An equivalent diameter refers to the diameter of a circle of the same area as the opening formed by an irregularly shaped hole on the surface of an object. That is, in the embodiments of the present application, the shapes of the first adjustment hole and the second adjustment hole are not limited. As long as the first adjustment rod can move within the first adjustment hole, the second adjustment rod can move within the second adjustment hole.

[0068] Within this range, the roof side rail 13 has sufficient adjustment space in the length direction, the width direction and the height direction of the vehicle.

[0069] In order to simplify the processing difficulty of the upper side beam 13 and the front mounting end plate 11, and in combination with the above-mentioned first adjusting rod and the second adjusting rod being configured as screws, in some embodiments of the present application, the first adjusting hole is configured as a circular hole, and the difference between the hole diameter of the first adjusting hole and the outer diameter of the first screw is 7 mm. Similarly, the difference between the hole diameter of the second adjusting hole and the outer diameter of the second screw is 7 mm.

[0070] Please refer to Figure 1 as well as Figure 2 As shown, in some embodiments of the present application, the front end structure 10 also includes a front collision beam assembly 15 and a first connecting member 16. The front collision beam assembly 15 is installed on the front mounting end plate 11; one end of the first connecting member 16 is connected to the upper side beam 13, and the other end is connected to the front collision beam assembly 15.

[0071] The front collision beam assembly 15 is a device used to reduce the impact energy absorbed when the vehicle is hit. In order to further protect pedestrians, in some embodiments of the present application, the front collision beam assembly 15 may include a main beam, a second energy absorption box and a mounting plate connected to the front mounting end plate 11, and the second energy absorption box is connected between the main beam and the mounting plate.

[0072] The first connecting member 16 is used to connect the front collision beam assembly 15 and the upper side beam 13. After the first connecting member 16 connects the front collision beam assembly 15 and the upper side beam 13, the first connecting member 16 simultaneously improves the stiffness and stability of the upper side beam 13 and the front collision beam assembly 15.

[0073] In order to more evenly enhance the structural strength of the roof side rail 13 , in some embodiments of the present application, along the width direction of the vehicle, the first connecting member 16 is connected to the center position of the front collision beam assembly 15 , and the first connecting member 16 is connected to the center position of the roof side rail 13 .

[0074] After the two ends of the upper side beam 13 are connected to the adjustment bracket 121, the two ends of the upper side beam 13 have sufficient structural strength. After the first connecting member 16 is connected to the middle position of the upper side beam 13, the first connecting member 16 reinforces the structure of the center position of the upper side beam 13, further improving the structural strength of the upper side beam 13, and the structural strength of the upper side beam 13 is more uniform.

[0075] Please refer to Figure 1 as well as Figure 2 As shown, in some embodiments of the present application, the front end structure 10 further includes a lower leg protection assembly 14, which includes a protective crossbeam 141 and a first energy absorption box 142. The protective crossbeam 141 is located in front of the front mounting end plate 11 along the length of the vehicle; the first energy absorption box 142 is connected between the protective crossbeam 141 and the front mounting end plate 11. The protective crossbeam 141 can effectively absorb collision energy in the event of a low-speed collision, minimizing damage to the vehicle body longitudinal rails and / or pedestrians caused by the impact force. The protective crossbeam 141 is well known to those skilled in the art and will not be described in detail again.

[0076] As a low-speed safety protection mechanism, the first energy absorption box 142 can absorb and disperse part of the impact force generated by the collision when a collision accident occurs. The first energy absorption box 142 constitutes the central part of the automobile bumper system. The first energy absorption box 142 has various types, which are not limited in the embodiments of the present application. All types of first energy absorption boxes 142 can absorb and disperse part of the impact force generated by the collision.

[0077] In the embodiments of the present application, there is no limit on the number of first energy absorption boxes 142. In some embodiments of the present application, there are two first energy absorption boxes 142, and the first energy absorption boxes 142 are located at corresponding ends of the protective beam 141. It is understood that the more first energy absorption boxes 142 there are, the greater the impact force generated by the collision can be absorbed and dispersed.

[0078] The calf protection assembly 14 in the embodiment of the present application further includes a crossbeam mounting end plate 143 , which is mounted on a side of the first energy absorption box 142 away from the protection crossbeam 141 and is fixedly connected to the front mounting end plate 11 .

[0079] The crossbeam mounting end plate 143 is used to realize the connection between the calf protection assembly 14 and the front mounting end plate 11. In the embodiment of the present application, the crossbeam mounting end plate 143 and the front mounting end plate 11 can be connected in any manner, for example, welding, riveting or bolt connection, etc. Considering that the first energy absorption box 142 of the vehicle absorbs energy and deforms after a collision accident, the vehicle needs to replace a new calf protection assembly 14, and a detachable connection method such as bolt connection can be preferably used.

[0080] Please refer to Figure 1 As shown, in some embodiments of the present application, the front end structure 10 further includes a second connecting member 17 , one end of the second connecting member 17 is connected to the calf protection assembly 14 , and the other end is connected to the front collision beam assembly 15 .

[0081] The second connecting member 17 is used to connect the front collision beam assembly 15 and the calf protection assembly 14. After the second connecting member 17 is connected to the front collision beam assembly 15 and the calf protection assembly 14, the stiffness and stability of the calf protection assembly 14 and the front collision beam assembly 15 are simultaneously improved.
