[0002] The related technology provides a front-end structure for a vehicle body, including a front bumper beam assembly and a front longitudinal beam.
[0003] However, due to the differences in front overhang length among different vehicle models, the front end structure of the vehicle body in related technologies needs to be designed with front anti-collision beam assemblies of different lengths or front longitudinal beams of different lengths to adapt to different front overhang lengths, resulting in higher costs. Utility Model Content
[0004] This application provides a front-end structure for a vehicle body and a vehicle in order to address the problem of how to reduce the cost of the front-end structure for a vehicle body.
[0005] According to one aspect of this application, a front-end structure for a vehicle body is provided, including a front bumper beam assembly, two adjusting brackets, and two front longitudinal beams. The front bumper beam assembly includes a front bumper beam and two energy-absorbing boxes, which are spaced apart and connected to the front bumper beam. Two adjusting brackets are respectively connected to the two energy-absorbing boxes. Two front longitudinal beams are respectively connected to the two adjusting brackets. Each adjusting bracket includes a first bracket and a second bracket, the second bracket being connected to the first bracket, and the first bracket being connected to a corresponding energy-absorbing box, and the second bracket being connected to a corresponding front longitudinal beam. The second bracket is movable relative to the first bracket along the length direction of the vehicle to change the distance between the energy-absorbing box and the front longitudinal beam along the length direction of the vehicle.
[0006] The aforementioned front-end structure allows for adjustment of the spacing between the energy-absorbing box and the front longitudinal beam along the vehicle's length by incorporating adjustable brackets. This makes the dimensions of the front-end structure adjustable along the vehicle's length, thus adapting to different front overhang lengths. Since there's no need to develop different front bumper beam assemblies or front longitudinal beams to suit different vehicle models, costs are reduced.
[0007] In some embodiments, the energy-absorbing box has a first cavity. A first bracket has a front end and a rear end that are opposite to each other along the length of the vehicle, with the front end passing through the first cavity. A second bracket is movably connected to the rear end.

[0009] In some embodiments, the reinforcing plate is connected to the cavity wall of the first cavity on both sides along the width direction of the vehicle. The clearance groove extends through the first bracket along the width direction of the vehicle and has a groove bottom surface opposite to the reinforcing plate along the length direction of the vehicle. The groove bottom surface can abut against the end of the reinforcing plate near the front longitudinal beam.
[0010] In some embodiments, the second bracket is slidably fitted over the first bracket along the length of the vehicle. The first bracket has a plurality of first mounting holes spaced apart along the length of the vehicle, and the second bracket has second mounting holes, which can correspond to any one of the first mounting holes. The front end structure of the vehicle body also includes a first fastener, which securely connects the first bracket and the second bracket to the front longitudinal beam through the second mounting holes and the corresponding first mounting holes.
[0011] In some embodiments, there are multiple second mounting holes, which are spaced apart along the length of the vehicle, and the distance between two adjacent second mounting holes along the length of the vehicle is equal to the distance between two adjacent first mounting holes along the length of the vehicle. There are multiple first fasteners, which are configured one-to-one with the multiple second mounting holes.
[0012] In some embodiments, the first bracket is provided with a limiting part, which can abut against the end of the second bracket away from the energy-absorbing box to limit the second bracket along the length direction of the vehicle.
[0013] In some embodiments, the front longitudinal beam has a second cavity with one end open. A second bracket extends through the opening along the length of the vehicle. The front longitudinal beam has a guide structure at the edge of the opening for guiding the second bracket into the second cavity.
[0014] In some embodiments, the guide structure includes a plurality of guide plates spaced apart from each other around the opening, one end of the guide plate being connected to the edge of the opening, and the other end of the guide plate being inclined toward the side away from the opening.

[0057] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0058] Example
[0059] Figure 1 This is a schematic diagram of the structure of a vehicle 1000 in one embodiment of this application; Figure 2 for Figure 1 A schematic diagram of the front end structure 100 of the vehicle body in the embodiment shown.
[0060] See Figure 1 and Figure 2 This application provides a vehicle 1000, including a front-end structure 100.
[0061] Figure 3 for Figure 1 A partial structural schematic diagram of the front end structure 100 of the vehicle body in the illustrated embodiment; Figure 4 for Figure 1 A schematic diagram of the front bumper beam assembly 10 in the embodiment shown; Figure 5 for Figure 1 A schematic diagram of the adjustment bracket 20 in the first use state in the illustrated embodiment.
[0062] See Figures 2 to 4 This embodiment provides a front-end structure 100 for a vehicle body, including a front anti-collision beam assembly 10, two adjusting brackets 20, and two front longitudinal beams 30.
[0063] The front bumper beam assembly 10 includes a front bumper beam 11 and two energy-absorbing boxes 12, which are connected to the front bumper beam 11 at intervals. Two adjusting brackets 20 are respectively connected to the two energy-absorbing boxes 12. Two front longitudinal beams 30 are respectively connected to the two adjusting brackets 20. Figure 5 As shown, the adjusting bracket 20 includes a first bracket 21 and a second bracket 22. The second bracket 22 is connected to the first bracket 21, and the first bracket 21 is connected to the corresponding energy-absorbing box 12. The second bracket 22 is connected to the corresponding front longitudinal beam 30. The second bracket 22 can move relative to the first bracket 21 along the length direction X of the vehicle 1000 to change the distance between the energy-absorbing box 12 and the front longitudinal beam 30 along the length direction X of the vehicle 1000.
[0064] The aforementioned front-end structure 100 of the vehicle body, by means of a second bracket 22, can move relative to the first bracket 21 along the length X of the vehicle 1000, making the distance between the energy-absorbing box 12 and the front longitudinal beam 30 adjustable along the length X of the vehicle 1000. This allows the dimensions of the front-end structure 100 along the length X of the vehicle 1000 to be adjustable, thus enabling it to adapt to different front overhang lengths and improving the versatility of the front-end structure 100 for different vehicle models 1000. Since there is no need to develop different front bumper beam assemblies 10 or front longitudinal beams 30 to adapt to different vehicle models, development costs and time are reduced, and the number of body-in-white types is reduced, simplifying the production line and lowering production line investment.
[0065] In some embodiments, such as Figures 4 to 6As shown, the energy-absorbing box 12 has a first cavity 12a. The first bracket 21 has a front end 211 and a rear end 212 opposite to each other along the length X of the vehicle 1000. The front end 211 passes through the first cavity 12a, and the second bracket 22 is movably connected to the rear end 212. Thus, the front end 211 of the first bracket 21 is connected to the energy-absorbing box 12, and the second bracket 22 can move relative to the rear end 212, so that the position of the front longitudinal beam 30 relative to the energy-absorbing box 12 along the length X of the vehicle 1000 is adjustable.
[0066] In some embodiments, such as Figure 4 and Figure 5 As shown, a reinforcing plate 121 is provided inside the first cavity 12a, and a clearance groove 211a is provided at the front end 211 to avoid the reinforcing plate 121. In this way, the structural strength of the energy-absorbing box 12 is improved by providing the reinforcing plate 121.
[0067] In some embodiments, such as Figure 4 As shown, there are multiple reinforcing plates 121, which are spaced apart from each other along the height direction Z of the vehicle 1000. Multiple clearance slots 211a correspond one-to-one with each of the multiple reinforcing plates 121. In this embodiment, there are two reinforcing plates 121 and two clearance slots 211a.
[0068] In some embodiments, such as Figure 4 and Figure 5 As shown, the reinforcing plate 121 is connected to the cavity walls of the first cavity 12a on both sides along the width direction Y of the vehicle 1000. The clearance groove 211a extends through the first bracket 21 along the width direction Y of the vehicle 1000. The clearance groove 211a has a groove bottom surface 2111 opposite to the reinforcing plate 121 along the length direction X of the vehicle 1000. The groove bottom surface 2111 can abut against the end of the reinforcing plate 121 near the front longitudinal beam 30. Thus, during assembly, the first bracket 21 and the energy-absorbing box 12 can be assembled into place when the groove bottom surface 2111 abuts against the reinforcing plate 121, thereby facilitating assembly.
[0069] Figure 6 for Figure 1 A schematic diagram of the adjustment bracket 20 in the second use state in the illustrated embodiment.
[0070] In some embodiments, such as Figure 5 and Figure 6 As shown, the second bracket 22 is slidably fitted onto the first bracket 21 along the length X of the vehicle 1000. The first bracket 21 has a plurality of first mounting holes 21a spaced apart along the length X of the vehicle 1000, and the second bracket 22 has second mounting holes 22a, which can correspond to any one of the first mounting holes 21a. (Combined with...) Figure 3As shown, the front end structure 100 of the vehicle body also includes a first fastener 40. The first fastener 40 securely connects the first bracket 21 and the second bracket 22 to the front longitudinal beam 30 through a second mounting hole 22a and a corresponding first mounting hole 21a. Thus, in use, by sliding the second bracket 22 outward from the first bracket 21, the first mounting hole 21a corresponding to the second mounting hole 22a can be changed, thereby adjusting the position of the second bracket 22 relative to the first bracket 21 along the length X of the vehicle 1000. By using the first fastener 40 to securely connect the first bracket 21 and the second bracket 22 to the front longitudinal beam 30, the connection reliability is improved and assembly is facilitated.
[0071] In other embodiments, the second bracket 22 is movably connected to the first bracket 21, and the end of the second bracket 22 away from the energy-absorbing box 12 can extend out of the first bracket 21 and connect to the front longitudinal beam 30, thereby increasing the adjustable range of the adjustment bracket 20 along the length direction X of the vehicle 1000.
[0072] In some embodiments, such as Figure 5 and Figure 6 As shown, there are multiple second mounting holes 22a, which are spaced apart along the length X of the vehicle 1000. The distance between two adjacent second mounting holes 22a along the length X of the vehicle 1000 is equal to the distance between two adjacent first mounting holes 21a along the length X of the vehicle 1000. There are multiple first fasteners 40, which are arranged one-to-one with the multiple second mounting holes 22a. In this way, the first bracket 21 and the second bracket 22 are fastened to the front longitudinal beam 30 by the multiple first fasteners 40, thereby further improving the connection reliability of the first bracket 21, the second bracket 22 and the front longitudinal beam 30. Furthermore, since the distance between two adjacent second mounting holes 22a along the length X of the vehicle 1000 is equal to the distance between two adjacent first mounting holes 21a along the length X of the vehicle 1000, the multiple second mounting holes 22a can remain concentric with the multiple first mounting holes 21a when the second bracket 22 is adjusted to different positions relative to the first bracket 21.
[0073] In some embodiments, such as Figure 5 and Figure 6 As shown, the first mounting holes 21a are arranged in multiple sets at intervals along the height direction Z of the vehicle 1000, and each set of first mounting holes 21a includes multiple sets arranged along the length direction X of the vehicle 1000. The second mounting holes 22a are also arranged in multiple sets at intervals along the height direction Z of the vehicle 1000, and each set of second mounting holes 22a includes multiple sets arranged along the length direction X of the vehicle 1000. The multiple sets of first mounting holes 21a correspond to the multiple sets of second mounting holes 22a. In this embodiment, there are two sets of both the first mounting holes 21a and the second mounting holes 22a.
[0074] In some embodiments, such as Figure 5 and Figure 6 As shown, each group of first mounting holes 21a includes three first mounting holes 21a, and each group of second mounting holes 22a includes two second mounting holes 22a. The first mounting adjustment bracket 20 has a first usage state and a second usage state. In the first usage state, the two second mounting holes 22a in the same group correspond to the two first mounting holes 21a in the corresponding group that are closer to the energy-absorbing box 12. In the second usage state, the two second mounting holes 22a in the same group correspond to the two first mounting holes 21a in the corresponding group that are farther away from the energy-absorbing box 12. Thus, in the first usage state, the front end structure 100 is suitable for vehicles 1000 with a shorter front overhang, and in the second usage state, the front end structure 100 is suitable for vehicles 1000 with a longer front overhang.
[0075] In some embodiments, such as Figure 5 and Figure 6 As shown, the first support 21 is provided with a limiting part 2121, which can abut against the second support 22 away from the energy-absorbing box 12 (see Figure 3 One end of the first bracket 21 is positioned to limit the second bracket 22 along the length X of the vehicle 1000, so as to prevent the second bracket 22 from detaching from the first bracket 21 during adjustment. Optionally, in the second use state, the limiting part 2121 abuts against the end of the second bracket 22 away from the energy-absorbing box 12.
[0076] In some embodiments, the first bracket 21 and the second bracket 22 are welded together, for example, by argon arc welding. In use, after the position of the second bracket 22 relative to the first bracket 21 along the length direction X of the vehicle 1000 is adjusted, the second bracket 22 is welded to the first bracket 21 to ensure that the second bracket 22 and the first bracket 21 are reliably fixed.
[0077] In some embodiments, such as Figure 3 As shown, the front end structure 100 of the vehicle body also includes a second fastener 50, which secures the first bracket 21 to the energy-absorbing box 12.
[0078] In other embodiments, the energy-absorbing box 12 is welded to the first bracket 21, and the second bracket 22 is welded to the front longitudinal beam 30.
[0079] Figure 7 for Figure 1 A schematic diagram of the front longitudinal beam 30 in the embodiment shown; Figure 8 for Figure 1 A partial structural schematic diagram of the front longitudinal beam 30 in the illustrated embodiment.
[0080] In some embodiments, combined with Figure 6 and Figure 7As shown, the front longitudinal beam 30 has a second cavity 30a with an open end 30b, and the second bracket 22 passes through the open end 30b along the length X of the vehicle 1000. The front longitudinal beam 30 has a guide structure 31 at the edge of the open end 30b, which guides the second bracket 22 into the second cavity 30a. Thus, by providing the guide structure 31, it is convenient to assemble the second bracket 22 into the front longitudinal beam 30.
[0081] In some embodiments, such as Figure 8 As shown, the guide structure 31 includes a plurality of guide plates 311, which are spaced apart from each other around the opening 30b. One end of the guide plate 311 is connected to the edge of the opening 30b, and the other end of the guide plate 311 is inclined toward the side away from the opening 30b, so as to align the second bracket 22 with the opening 30b during assembly and to guide the second bracket 22 into the second cavity 30a.

Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
