[0031] Some embodiments of the present application are described in detail. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] Embodiments

[0033] Figure 1 A vehicle 100 according to an embodiment of the present application is shown.

[0034] The vehicle 100 can be, for example, a fuel vehicle (such as a gasoline vehicle, a diesel vehicle, etc.), an electric vehicle (such as a pure electric vehicle, a fuel cell vehicle), or a hybrid electric vehicle.

[0035] The vehicle 100 has a length direction X, a width direction Y, and a height direction Z. The length direction X is the front-rear direction of the vehicle 100, the width direction Y is the left-right direction of the vehicle 100, and the height direction Z is the up-down direction of the vehicle 100.

[0036] Figure 2 A part view of the vehicle 100 according to the embodiment is shown. Figure 3 Another part view of the vehicle 100 according to the embodiment is shown, Figure 4 Another perspective view of Figure 3 is shown.

[0037] Referring to Figure 2 , the vehicle 100 includes a gas tank 101 and an air spring controller 102. The gas tank 101 and the air spring controller 102 are both arranged in a bottom storage box 103 of a rear trunk. In some embodiments, the bottom storage box 103 is a plastic part.

[0038] Referring to Figure 3 and Figure 4The vehicle 100 is further provided with the air pump 21. In the embodiment, the air pump 21 is a closed air spring air pump.

[0039] In the embodiment, the air pump 21 is arranged at the rear end of the rear trunk, so as to reduce the length of the pipeline between the air pump 21 and the air tank 101.

[0040] In consideration of the noise, vibration and harshness (NVH) problem, the air pump 21 in the embodiment is arranged outside the vehicle 100 and is shielded and protected by the rear lower apron 104 of the vehicle 100. The rear lower apron 104 is arranged to be detachable, so that the air pump 21 can be repaired by detaching the rear lower apron 104, which is convenient to operate. Alternatively, the air pump 21 is assembled in a high position, has a wide field of view, and has sufficient hand operation space, which is beneficial to disassembly and repair.

[0041] Continuing to refer to Figure 3 and Figure 4 , in the embodiment, the air pump 21 is connected below the longitudinal beam 110 (such as the rear longitudinal beam) of the vehicle 100 and above the rear lower apron 104.

[0042] Hereinafter, the connection structure of the air pump 21 and the longitudinal beam 110 in the embodiment will be mainly introduced.

[0043] Referring to Figures 5-7 , the embodiment provides an air pump connection structure 120, which comprises a bridging bracket 10 and first and second fixing structures 30 and 40 spaced from each other.

[0044] The air pump 21 is fixedly connected to the bridging bracket 10, and the first and second fixing structures 30 and 40 are used to fix the bridging bracket 10 to the bottom surface P1 (i.e. the side facing downward along the height direction Z of the vehicle 100) of the longitudinal beam 110, and the connecting line L1 of the first and second fixing structures 30 and 40 is obliquely intersected with the length direction X of the vehicle 100. The connecting line L1 of the first and second fixing structures 30 and 40 can be the connecting line L1 of the center points of the first and second fixing structures 30 and 40. The first and second fixing structures 30 and 40 can be fixed connection structures such as bolts, screws and rivets, and at this time, the center points of the first and second fixing structures 30 and 40 can be located on the central axes of the corresponding bolts, screws or rivets, or be the center points of the first matching holes K1 matched with the bolts, screws or rivets.

[0045] In the embodiment, the air pump 21 is connected to the bridging support 10, the bridging support 10 is connected to the longitudinal beam 110 through the first fixing structure 30 and the second fixing structure 40, and the connecting line L1 of the first fixing structure 30 and the second fixing structure 40 is obliquely intersected with the length direction X of the vehicle 100, so that the connecting rigidity of the air pump 21 along the length direction X of the vehicle 100 can be improved, and the vibration and noise can be reduced.

[0046] In the embodiment, the longitudinal beam 110 extends along the length direction X of the vehicle 100, the bridging support 10 is a strip-shaped structure extending along the width direction Y of the vehicle 100, and includes the middle section 11 and the two extending sections 12. The middle section 11 is overlapped with the longitudinal beam 110 and is fixedly connected to the longitudinal beam 110 through the first fixing structure 30 and the second fixing structure 40. The two extending sections 12 are respectively connected to the two ends of the middle section 11 and extend out of the longitudinal beam 110 along the width direction Y of the vehicle 100. The air pump connecting structure 120 further includes the two first connecting parts 50, which are respectively located at the two extending sections 12 and respectively connect the corresponding extending sections 12 to the air pump 21, so as to realize the mutual fixation with the air pump 21. The extending sections 12 extending out of the longitudinal beam 110 are connected to the air pump 21, so that the bridging support 10 and the air pump 21 can be conveniently connected through bolts or other fastening structures, and are avoided from being hindered by the longitudinal beam 110. Optionally, the second matching holes K2 can be formed on the extending sections 12 to match the first connecting parts 50.

[0047] Optionally, the air pump connecting structure 120 further includes the air pump support 22. The air pump 21 is connected to the air pump support 22 and is connected to the bridging support 10 through the air pump support 22. In some embodiments, the air pump support 22 and the air pump 21 can be detachably connected or non-detachably connected (such as riveting).

[0048] Optionally, the first fixing structure 30 and the second fixing structure 40 are respectively located on the two sides of the connecting line L3 of the two first connecting parts 50. In this way, the load applied to the two first connecting parts 50 by the air pump 21 and the air pump support 22 can be more evenly transmitted to the longitudinal beam 110 by the front and rear arranged first fixing structure 30 and the second fixing structure 40, and the structure stress condition is more reasonable.

[0049] Reference is mainly made to Figure 6 and Figure 7In the embodiment, the longitudinal beam 110 includes a longitudinal beam body 111, a longitudinal beam reinforcing plate 112, and a plurality of riveting portions 113. The longitudinal beam reinforcing plate 112 is fixedly connected to the outer side of the longitudinal beam body 111 through the plurality of riveting portions 113, and the plurality of riveting portions 113 are distributed in a plane. The first fixing structure 30 and the second fixing structure 40 are respectively connected to the area of the longitudinal beam 110 covered by the longitudinal beam reinforcing plate 112. In this way, the riveting portions 113 distributed in the plane can ensure that the longitudinal beam body 111 and the longitudinal beam reinforcing plate 112 are reliably connected together. The longitudinal beam reinforcing plate 112 can improve the thickness and structural strength of the area of the longitudinal beam 110 connected to the bridge support 10.

[0050] Optionally, in the embodiment, the riveting portions 113 are three, and the three riveting portions 113 are distributed in a triangle. Two of the three riveting portions 113 are first riveting portions 113a, and the other one is a second riveting portion 113b. The two first riveting portions 113a are spaced apart along the width direction Y of the vehicle 100, and the second riveting portion 113b is spaced apart from the line L2 connecting the two first riveting portions 113a along the length direction X of the vehicle 100. In this way, the longitudinal beam body 111 and the longitudinal beam reinforcing plate 112 can have higher structural rigidity in both the length direction X and the width direction Y of the vehicle 100.

[0051] It should be noted that, Figure 6 and Figure 7 the longitudinal beam 110 in FIGS. 11A and 11B is a schematic view of the longitudinal beam 110 after the riveting portions 113 are riveted but before the excess rivet rod segments 114 are removed. The excess rivet rod segments 114 need to be removed from the longitudinal beam 110 eventually. Figure 5 The longitudinal beam 110 in FIGS. 12A and 12B also has rivet rod segments 114 that need to be removed.

[0052] Continuing to refer to Figures 5-7 In the embodiment, the first fixing structure 30 is located between the second riveting portion 113b and one of the first riveting portions 113a, the second fixing structure 40 is spaced apart from the second riveting portion 113b along the width direction Y, and the three riveting portions 113 and the second fixing structure 40 are distributed in a quadrilateral. The first fixing structure 30 and the second fixing structure 40 are both located in the covered area of the longitudinal beam reinforcing plate 112, so as to ensure that the bridge support 10 is connected to the area of the longitudinal beam 110 with high structural strength. Moreover, the second riveting portion 113b and one of the first riveting portions 113a are respectively located on the two sides of the first fixing structure 30, which is conducive to jointly bearing the load received by the first fixing structure 30 and ensuring that the structure is reasonably and stably stressed. At the same time, the foregoing quadrilateral arrangement can further ensure the connection strength of the longitudinal beam body 111 and the longitudinal beam reinforcing plate 112.

[0053] Referring again to Figure 5In this embodiment, the air pump connection structure 120 further includes a second connection part 60, which is used to connect the longitudinal beam 110 and the air pump bracket 22. A third mating hole K3 can be provided on the longitudinal beam 110 (see...). Figure 6 The second connecting part 60 is used to connect the two first connecting parts 50. The second connecting part 60 and the two first connecting parts 50 are arranged in a triangle to ensure that the air pump bracket 22 is reliably connected to the longitudinal beam 110 and has high rigidity in both the length direction X and the width direction Y of the vehicle 100.

[0054] In some known technologies, the connection points of the vehicle's air pump are connected to plastic parts such as the bottom storage box 103 of the vehicle 100, which results in insufficient connection rigidity and easily generates and transmits noise and vibration.

[0055] In contrast, in this embodiment, the air pump bracket 22 is connected to the bridging bracket 10 on the longitudinal beam 110 through two first connecting parts 50, and is also directly connected to the longitudinal beam 110 through a second connecting part 60. The connection is reliable and has high rigidity, which helps to reduce NVH problems.

[0056] See Figure 8 (See also) Figure 5 In this embodiment, the air pump 21 and the air pump bracket 22 can be connected by welding, screw connection, riveting, snap-fit, etc. The second connecting part 60 is used to connect the longitudinal beam 110 and the air pump bracket 22, and the two first connecting parts 50 are used to connect the air pump bracket 22 and the two protruding sections 12 of the bridging bracket 10, respectively.

[0057] In this embodiment, the air pump 21 is located below the longitudinal beam 110. In the plane perpendicular to the height direction Z of the vehicle 100, the second connecting part 60 and the two first connecting parts 50 are located outside the air pump 21. Furthermore, the second connecting part 60 and the two first connecting parts 50 are configured to detachably connect the air pump bracket 22 to the longitudinal beam 110 and the bridging bracket 10 from bottom to top. Thus, when it is necessary to remove the air pump 21, after the rear lower guard plate 104 of the vehicle 100 is removed, the second connecting part 60 and the two first connecting parts 50 can be removed from bottom to top, and the air pump 21 and the air pump bracket 22 can be removed as a whole, which is convenient and quick.

[0058] Figure 9 for Figure 5 Sectional view along line AA Figure 10 for Figure 5 A cross-sectional view along line BB. Line AA here coincides with the aforementioned connecting line L3.

[0059] See Figure 9In the embodiment, the first connecting portion 50 is arranged to provide buffering between the air pump support 22 and the bridging support 10. For example, the first connecting portion 50 includes a first screw 51 and a first elastic bushing 52. The first elastic bushing 52 is fixed to the air pump support 22, and the first screw 51 is screwed to the bridging support 10 after passing through the first elastic bushing 52. In this way, the first elastic bushing 52 provides elastic buffering between the air pump support 22 and the bridging support 10.

[0060] Referring to Figure 10 The second connecting portion 60 is arranged to provide buffering between the air pump support 22 and the longitudinal beam 110. For example, the second connecting portion 60 includes a second screw 61, a second elastic bushing 62, and a connecting nut 63. The second elastic bushing 62 is fixed to the air pump support 22, and the second screw 61 is screwed to the connecting nut 63 inside the longitudinal beam 110 after passing through the second elastic bushing 62 and the longitudinal beam 110. In this way, the second elastic bushing 62 provides elastic buffering between the air pump support 22 and the longitudinal beam 110.

[0061] Of course, the specific structure of the first connecting portion 50 and the second connecting portion 60 described above is only an example. In other embodiments, the first connecting portion 50 and the second connecting portion 60 can also be arranged in any other connecting form, which is not limited herein.

[0062] Referring to Figure 11 The embodiment also provides another longitudinal beam 110a, which is different from the longitudinal beam 110 in that the number of riveting portions 113 is two, and the first fixing structure 30, the second fixing structure 40, and the two riveting portions 113 are arranged in a quadrilateral. Figure 6

[0063] Figure 11 The first fixing structure 30 and the second fixing structure 40 in the longitudinal beam 110a are also arranged to be obliquely intersected with the length direction X of the vehicle 100, so that the connecting rigidity of the bridging support 10 and the longitudinal beam 110a in the length direction X of the vehicle 100 is also improved.

[0064] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit the present application. Although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application.​
