Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features.

[0032] The embodiment of the present application provides a mounting structure 100 of a vehicle-mounted air pump 200, which is used for mounting the vehicle-mounted air pump 200 on a vehicle body. The vehicle-mounted air pump 200 is a high-pressure air source, which can perform cleaning work on the surface of a sensor of the vehicle, so that the sensor can collect real environmental information. The vehicle-mounted air pump 200 is usually provided with a reciprocating piston, and the reciprocating movement of the piston will cause the vehicle-mounted air pump 200 to vibrate when the vehicle-mounted air pump 200 works.

[0033] Please refer to Figure 1 to Figure 4 In the embodiment, the mounting structure 100 comprises a bottom plate 10, an adapter plate 20, a first damper 30 and a second damper 40. The bottom plate 10 is fixedly mounted on the vehicle body. The adapter plate 20 is mounted on the bottom plate 10 through the first damper 30, and the adapter plate 20 and the bottom plate 10 are arranged in parallel with each other. The side, away from the bottom plate 10, of the adapter plate 20 is provided with a mounting surface 21. The vehicle-mounted air pump 200 is mounted on the mounting surface 21 through the second damper 40.

[0034] The bottom plate 10 and the adapter plate 20 mentioned above are usually made of metal materials, and of course, they can also be made of other materials, such as hard plastic, hard wood and the like. The shapes of the bottom plate 10 and the adapter plate 20 are various, which can be square plate bodies, rectangular plate bodies or even circular plate bodies. When the material of the bottom plate 10 is a metal material, the bottom plate 10 can be fixedly mounted on the vehicle body through welding, riveting, bolt connection and the like.

[0035] The structures of the first damper 30 and the second damper 40 can be the same or different. Figure 3 In the example shown in the figure, the specific structure of the first damper 30 is different from that of the second damper 40. The first damper 30 and the second damper 40 comprise but are not limited to steel wire rope dampers, metal rubber dampers and rubber dampers, and the main function thereof is to reduce vibration and impact.

[0036] It can be understood that, when the bottom plate 10 is mounted on the vehicle body, the bottom plate 10 is parallel to the horizontal plane. Since the adapter plate 20 is parallel to the bottom plate 10, the mounting surface 21 is also parallel to the horizontal plane.

[0037] The mounting structure 100 of the vehicle-mounted air pump 200 provided by the embodiment of the present application is configured as above. When the vehicle-mounted air pump 200 is working, the vibration generated by the vehicle-mounted air pump 200 needs to pass through the second damper 40 before being transmitted to the adapter plate 20, and the vibration of the adapter plate 20 needs to pass through the first damper 30 before being transmitted to the bottom plate 10, and finally transmitted to the vehicle body. The first damper 30 and the second damper 40 respectively weaken the vibration generated by the vehicle-mounted air pump 200, thereby weakening the vibration transmitted to the vehicle body. It can be seen that the technical solution of the present application gradually weakens the vibration generated by the vehicle-mounted air pump 200 by using the second damper 40 and the first damper 30, thereby reducing the vibration and the noise caused by the vibration, and greatly improving the user's driving experience. At the same time, the vibration transmitted to the vehicle body is weakened by the mounting structure 100, thereby reducing the risk of screw loosening caused by vibration.

[0038] It is considered that the vehicle-mounted air pump 200 is connected to the vehicle body through the first damper 30 and the second damper 40, so that the modal frequency of the vehicle system is low, which improves the comfort of the user riding the vehicle, but this may reduce the reliability of the vehicle-mounted air pump 200 installed on the vehicle body.

[0039] In some examples, as shown in Figure 1 to Figure 3 The mounting structure 100 further comprises a buffer assembly and a limiting assembly fixedly arranged. The limiting assembly is further arranged around the periphery of the adapter plate 20, and the buffer assembly is fixedly arranged on the periphery of the adapter plate 20 to cooperate with the limiting assembly to limit the movement of the adapter plate 20 in the direction parallel to the mounting surface 21.

[0040] The limiting assembly can be fixedly arranged by being fixedly connected to the bottom plate 10, or can be fixedly arranged by being fixedly connected to the vehicle body. Considering the convenience of installation of the mounting structure 100, preferably, the limiting assembly is fixedly arranged by being fixedly connected to the bottom plate 10.

[0041] In this way, the buffer assembly and the limiting assembly are arranged to cooperate to limit the movement of the adapter plate 20 in the direction parallel to the mounting surface 21, so that the adapter plate 20 and the vehicle-mounted air pump 200 can only move in a smaller range in the direction parallel to the mounting surface 21, thereby improving the reliability of the vehicle-mounted air pump 200 installed on the vehicle body.

[0042] In some examples, as shown in Figure 1 to Figure 3 The adapter plate 20 has two first side edges 22 parallel to each other and two second side edges 23 parallel to each other, and the first side edges 22 are arranged perpendicular to the second side edges 23. The buffer assembly comprises four buffer pads 50, and the four buffer pads 50 are respectively located on the two first side edges 22 and the two second side edges 23. The material of the buffer pad 50 is usually rubber.

[0043] In this way, the cooperation between the buffer assembly and the limiting assembly is optimized, the movement of the adapter plate 20 and the vehicle-mounted air pump 200 in four directions is limited by the cooperation between the four buffer pads 50 and the limiting assembly in four directions, and the reliability of the vehicle-mounted air pump 200 mounted on the vehicle body is further improved. Meanwhile, one buffer pad 50 is installed on each side edge, which can improve the standardization of the mounting structure 100 and reduce the assembly difficulty.

[0044] In some examples, as shown in Figure 1 to Figure 3 The limiting assembly includes four limiting plates 60, which are fixedly connected with the bottom plate 10, and extend towards the adapter plate 20 in a direction perpendicular to the mounting surface 21 to correspond to the four buffer pads 50.

[0045] It should be noted that the four limiting plates 60 can be integrally provided with the bottom plate 10, that is, the four limiting plates 60 can be produced by edge folding process of the bottom plate 10, and the four limiting plates 60 can also be fixedly connected with the bottom plate 10 by welding process.

[0046] In this way, the limiting assembly is fixedly arranged and installed, and the overall strength of the bottom plate 10 is improved, thereby improving the reliability of the mounting structure 100.

[0047] In some examples, as shown in Figure 1 to Figure 3 The mounting structure 100 further includes four mounting plates 70, which are arranged one by one with the four buffer pads 50, and the mounting plate 70 is arranged perpendicular to the mounting surface 21, and the buffer pad 50 is fixedly installed on the peripheral side of the adapter plate 20 through the mounting plate 70.

[0048] It should be noted that the four mounting plates 70 can be integrally provided with the adapter plate 20, that is, the four limiting plates 60 can be produced by edge folding process of the adapter plate 20, and the four limiting plates 70 can also be fixedly connected with the adapter plate 20 by welding process.

[0049] In this way, the reliability of the buffer pad 50 installed on the peripheral side of the adapter plate 20 is improved, and the overall strength of the adapter plate 20 is improved, thereby improving the reliability of the mounting structure 100.

[0050] In some examples, as shown in Figure 1 to Figure 3 and Figure 6 Each mounting plate 70 is provided with an abutting surface 71 on the side facing the limiting assembly, one side of the buffer pad 50 abuts against the abutting surface 71, and the side of the buffer pad 50 away from the abutting surface 71 is provided with a plurality of grooves 51, the plurality of grooves 51 are arranged in the length direction of the buffer pad 50, and the plurality of grooves 51 are arranged in the direction perpendicular to the mounting surface 21.

[0051] In this way, the contact area between the cushion 50 and the mounting plate 70 is increased, and the reliability of the mounting of the cushion 50 on the peripheral side of the adapter plate 20 is further improved. The static friction between the cushion 50 and the mounting plate 70 can also be increased.

[0052] In some examples, as shown in Figure 1 to Figure 3 The cushion 50 is fixedly mounted on the mounting plate 70 by a screw structure. In this way, the reliability of the connection between the cushion 50 and the mounting plate 70 is improved. Of course, in other examples, the cushion 50 can be fixedly connected to the mounting plate 70 by bonding, clamping, or other connection methods.

[0053] In some examples, as shown in Figure 1 to Figure 4 The mounting structure 100 includes four second dampers 40, and the vehicle-mounted air pump 200 is mounted on the mounting surface 21 through the four second dampers 40. The four second dampers 40 are distributed at the four corners of the adapter plate 20. The mounting structure 100 includes four first dampers 30, and the adapter plate 20 is mounted on the base plate 10 through the four first dampers 30. The four first dampers 30 are distributed on the inner side of the four second dampers 40. In this way, the connection between the vehicle-mounted air pump 200 and the vehicle body is enhanced. At the same time, the overall layout of the mounting structure 100 is optimized, and the space occupied by the mounting structure 100 is reduced.

[0054] In some examples, as shown in Figure 3 The adapter plate 20 is provided with a hollow portion 24, and / or the base plate 10 is provided with a hollow portion 24. In this way, the self-weight of the mounting structure 100 is reduced, and the load of the vehicle is reduced.

[0055] In some examples, as shown in Figure 2 to Figure 5 The base plate 10 and the adapter plate 20 are each provided with a first through hole. The first damper 30 includes a first bolt 31, a first damping member, and two first nuts 33. The first bolt 31 penetrates the first damping member, and the first damping member is located at the middle of the length direction of the first bolt 31. The two ends of the first bolt 31 respectively pass through the first through holes of the base plate 10 and the adapter plate 20 to be threadedly connected with the first nuts 33. The first damping member includes, but is not limited to, a rubber block, a sleeve spring, and an air bag.

[0056] In this way, the first damping member is clamped between the base plate 10 and the adapter plate 20. The first damper 30 absorbs the energy generated by the vibration through the first damping member to weaken the vibration.
