[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] like Figures 1-4 As shown, this application embodiment provides an air pump assembly, including a connecting bracket 1, a first elastic pad 4, and an air pump 5; the connecting bracket 1 has an installation area, and a plurality of first connecting holes are formed on the connecting bracket 1. The first connecting holes are installed and connected to the vehicle body through first fasteners 2, and an elastic spacer is provided between the first connecting holes and the first fasteners 2; the first elastic pad 4 is covered and disposed on the installation area; the air pump 5 is pressed on the first elastic pad 4, and the air pump 5 is installed and connected to the installation area through second fasteners 6.

[0038] With this configuration, in the air pump assembly provided in this application, the mounting area of ​​the connecting bracket 1 provides a connection position for the air pump 5, and a first elastic pad 4 is provided between the mounting area and the air pump 5. Since the first elastic pad 4 exists in the fastening connection between the air pump 5 and the connecting bracket 1, it is beneficial to the stable installation of the air pump 5, and also effectively plays a vibration isolation role between the air pump 5 and the connecting bracket 1. In addition, the connecting bracket 1 is used for installation connection with the vehicle body, and the elastic spacer between the first connecting hole and the first fastener 2 plays a vibration isolation role between the connecting bracket 1 and the vehicle body, realizing the secondary vibration isolation installation of the air pump 5, and solving the problem of how to reduce the vibration of the air pump 5 of the air suspension system on the NVH impact of the vehicle in the prior art.

[0039] In some other specific embodiments, the air pump 5 is provided with a threaded blind hole 501 that engages with the threaded fastener 6, a second connecting hole 101 is provided in the mounting area, and a first through hole is provided in the first elastic pad 4 for the second fastener 6 to pass through; the second fastener 6 passes through the second connecting hole 101 and the first elastic pad 4, and is threadedly connected to the threaded blind hole 501. The second fastener 6 can be a bolt, screw, etc.

[0040] With this configuration, the air pump 5 is connected to the connecting bracket 1 via a blind hole threaded connection. The tight fit between the second fastener 6 and the threaded blind hole 501 can enhance the structural stability of the air pump assembly, reduce the possibility of vibration and loosening. Moreover, this connection can also disperse stress, reduce stress concentration, and improve the strength and reliability of the connection. Combined with the first elastic pad 4, it can further enhance the vibration isolation effect and also help to extend the service life of the connecting bracket 1.

[0041] Of course, in addition to the above methods, it is also feasible for the air pump 5 to be equipped with a connecting ear and the second fastener 6 to be a bolt and nut assembly, with the connecting ear connected to the mounting area through the bolt and nut assembly.

[0042] In some other alternative embodiments, the air pump assembly further includes a second elastic pad 7 covering the side of the mounting area opposite to the first elastic pad 4. The second elastic pad 7 has a second through hole through which a second fastener 6 passes. The head of the second fastener 6 is pressed against the second elastic pad 7 and the second fastener 6 penetrates the second elastic pad 7.

[0043] With this configuration, elastic pads are installed on both sides of the mounting area of ​​the connecting bracket 1, which can further reduce the possibility of the second fastener 6 transmitting vibration to the connecting bracket 1 and further improve the vibration isolation effect between the air pump 5 and the connecting bracket 1.

[0044] It should be noted that the first elastic pad 4 and the second elastic pad 7 may be, but are not limited to, made of materials such as rubber or silicone.

[0045] In some other preferred embodiments, the connecting bracket 1 is provided with a receiving recess 102, and the second elastic pad 7 is located in the receiving recess 102.

[0046] This configuration allows the recessed 102 to position the second elastic pad 7, enabling it to be quickly placed into place, which in turn facilitates faster assembly and installation of the air pump assembly. Simultaneously, it prevents the bolt head of the second fastener 6 from protruding excessively from the connecting bracket 1, thus preventing the second fastener 6 from interfering with other components in the installation environment and saving installation space for the air pump assembly. Furthermore, partial material reduction also contributes to the lightweight design of the connecting bracket 1.

[0047] In some other preferred embodiments, one side of the first elastic pad 4 has a raised structure, and the other side has a recessed structure opposite to the raised structure. That is, the protrusion on one side is formed by the recess on the other side, and the concave-convex design can be formed by injection molding. With this configuration, the concave-convex design of the first elastic pad 4 can further absorb and disperse vibrations, and improve the vibration reduction and buffering effect.

[0048] In some other preferred embodiments, one side of the second elastic pad 7 has a raised structure, and the other side has a recessed structure opposite to the raised structure. That is, the protrusion on one side is formed by the recess on the other side, and the concave-convex design can be formed by injection molding. With this configuration, the concave-convex design of the second elastic pad 7 can further absorb and disperse vibrations, and improve the vibration reduction and buffering effect.

[0049] In some other specific embodiments, the connecting bracket 1 has a bent plate-like structure, including a first plate portion 11, a second plate portion 12, and a third plate portion 13; the second plate portion 12 is bent and connected to the first plate portion 11; the third plate portion 13 is bent and connected to the second plate portion 12, the third plate portion 13 and the first plate portion 11 are respectively located on opposite sides of the second plate portion 12, and the third plate portion 13 and the first plate portion 11 extend in opposite directions; wherein, both the first plate portion 11 and the third plate portion 13 are provided with a first connecting hole; the air pump 5 is located in the included angle space formed by the first plate portion 11 and the second plate portion 12, that is, the air pump 5 is opposite to both the first plate portion 11 and the second plate portion 12. Figure 1 and Figure 2 As exemplarily shown, the installation area is located on the first plate 11.

[0050] With this configuration, the vehicle body structure has numerous components, and the mounting surface is often difficult to be a regular plane. The connecting bracket 1 is designed with a multi-bend structure, making it easy to adapt and install to the vehicle body; for example, such as... Figure 2 As shown, the connecting bracket 1 is installed on the surfaces of two components with a height difference in the Z direction of the vehicle body.

[0051] In some alternative embodiments, the edge of the connecting bracket 1 is provided with a reinforcing flange.

[0052] In some other preferred embodiments, the connecting bracket 1 further includes an inclined plate portion 14 and a connecting portion 15; the inclined plate portion 14 is located at the edge of the connecting bracket 1 and folds from the first plate portion 11 toward the side where the air pump 5 is located, the inclined plate portion 14 is connected between the first plate portion 11 and the third plate portion 13, or the inclined plate portion 14 is located in the included angle space enclosed by the first plate portion 11 and the second plate portion 12, and there is an acute included angle between the inclined plate portion 14 and the second plate portion 12; the connecting portion 15 is transitionally connected to the inclined plate portion 14, the second plate portion 12 and the first plate portion 11, and the connecting portion 15, the second plate portion 12 and the first plate portion 11 form an accommodating angle that matches the corner of the air pump 5.

[0053] With this design, during the installation and connection of the air pump 5 and the connecting bracket 1, after the air pump 5 is placed on the connecting bracket 1, the inclined plate portion 14 and the joint portion 15 can form a limiting stop for the air pump 5, so as to quickly position the air pump 5, thereby facilitating the assembly and installation of the air pump assembly. In addition, the design of the inclined plate portion 14 on one side of the connecting bracket 1 can reduce the use of production materials, realize the weight reduction of the connecting bracket 1, and make the connecting bracket 1 have a lightweight design. Moreover, the inclined plate portion 14 can also strengthen the structural strength of the connecting bracket 1 and save the installation space occupied by the air pump assembly.

[0054] In some other specific embodiments, the first plate portion 11 has a mounting area, and the first fastener 2 connects the first plate portion 11 to the vehicle body along the Z-direction of the vehicle body. The air pump 5 is mounted above the mounting area, that is, the air pump 5 is mounted to the mounting area along the Z-direction of the vehicle body. Figure 2 As shown. The Z-axis of the vehicle body is the direction of vehicle height.

[0055] With this configuration, the length direction of the second fastener 6 is in the same direction as the Z-axis of the vehicle body. The second fastener 6 will not be subjected to adverse shearing forces caused by the weight of the air pump 5, thus ensuring the assembly stability of the air pump assembly.

[0056] In some other specific embodiments, the elastic spacer is an elastic bushing 3 disposed in the first connecting hole, and the elastic bushing 3 protrudes from the surface of the connecting bracket 1 along the through direction of the first connecting hole, and the first fastener 2 is located in the elastic bushing 3. Specifically, the elastic bushing 3 includes a hollow rubber column and a sleeve located in the rubber column, the rubber column and the sleeve are vulcanized as one piece, and the sleeve provides support. The first fastener 2 can be a bolt, screw, etc.

[0057] With this configuration, since the elastic bushing 3 protrudes from the surface of the connecting bracket 1, when the connecting bracket 1 is installed and connected to the vehicle body, the end of the elastic bushing 3 abuts against the vehicle body before the connecting bracket 1, which helps to achieve a better vibration isolation effect.

[0058] Of course, in addition to the above methods, it is also feasible to have the elastic spacer as a rubber gasket set on both sides of the first connecting hole, with the first fastener 2 passing through the rubber gasket.

[0059] Based on the air pump assembly described above, this application also provides a vehicle that includes the aforementioned air pump assembly. Since the vehicle has the air pump assembly, the beneficial effects of the air pump assembly on the vehicle are described above and will not be repeated here.
