[0029] Embodiment 1

[0030] Refer to Figures 1 to 4As shown, the air pump mounting structure provided in the present application includes a mounting bracket 101 , a first connecting component 102 and a second connecting component 103 .

[0031] The first connecting component 102 includes a first connecting member 104 and a first vibration-damping bushing 105. The first connecting member 104 is used to connect the air pump 106 and the mounting bracket 101, and the first vibration-damping bushing 105 is sleeved on the first connecting member 104; the second connecting component 103 includes a second connecting member 107 and a second vibration-damping bushing 108. The second connecting member 107 is used to connect the mounting bracket 101 and the frame, and the second vibration-damping bushing 108 is sleeved on the second connecting member 107.

[0032] Specifically, the present application directly mounts the air pump 106 on the mounting bracket 101 through the first connecting component 102, and the mounting bracket 101 is directly connected to the frame through the second connecting component 103. Compared with the prior art, the present application reduces the number of brackets, thereby reducing the space occupied by the air pump mounting structure. Preferably, the mounting bracket 101 is a casting, and the mounting bracket 101 is provided with reinforcing ribs to increase the strength of the mounting bracket 101, so that the present solution only needs to set up one mounting bracket 101 to connect the air pump 106 to the frame.

[0033] Furthermore, the first connection assembly 102 includes a first connection member 104 and a first vibration-damping bushing 105. When the first connection member 104 connects the air pump 106 to the mounting bracket 101, the first vibration-damping bushing 105 sleeved on the first connection member 104 can reduce the vibration of the connection between the air pump 106 and the mounting bracket 101, and can effectively isolate the vibration of the air pump 106 from being transmitted to the mounting bracket 101, thereby achieving a primary vibration-damping effect. The second connection assembly 103 includes a second connection member 107 and a second vibration-damping bushing 108. When the second connection member 107 connects the mounting bracket 101 to the vehicle frame, the second vibration-damping bushing 108 sleeved on the second connection member 107 can reduce the vibration of the connection between the mounting bracket 101 and the vehicle frame, and can suppress the shaking of the mounting bracket 101, and can block the vibration of the mounting bracket 101 from being transmitted to the vehicle frame and the passenger compartment, thereby achieving a secondary vibration-damping effect.

[0034] The air pump mounting structure provided in the present application can reduce the space occupied by the air pump mounting structure by providing a mounting bracket 101 to connect the air pump 106 to the frame; and the first connecting component 102 and the second connecting component 103 are provided to connect the air pump 106, the mounting bracket 101 and the frame in sequence, and generate a secondary vibration reduction effect between the air pump 106 and the frame, thereby improving the vibration reduction effect.

[0035] In an optional solution of this embodiment, the first vibration-damping bushing 105 has a first stiffness value, and the second vibration-damping bushing 105 has a second stiffness value.

[0036] In this embodiment, the stiffness of the shock-absorbing bushing is a parameter that measures its elastic characteristics when subjected to pressure, and it determines the recovery ability of the shock-absorbing bushing when subjected to impact. The greater the stiffness, the stronger the recovery ability of the shock-absorbing bushing when subjected to impact, but too large a stiffness will result in a poor shock-absorbing effect. In this application, the first shock-absorbing bushing 105 and the second shock-absorbing bushing 108 are set to have different stiffnesses, increasing the types and functions of the bushings, ensuring that the overall structure can effectively absorb, reduce vibration and impact, and also have sufficient recovery ability when subjected to impact.

[0037] In an alternative embodiment of this embodiment, the first stiffness value is less than 10 N / mm. Specifically, the first shock-absorbing bushing 105 can be composed of a spring, a formed sheath and a gasket made of rubber. The second stiffness value is less than 200 N / mm. Specifically, the second shock-absorbing bushing 108 can be formed of metal and rubber.

[0038] In this embodiment, the first shock-absorbing bushing 105 is located between the air pump 106 and the mounting bracket 101. The air pump 106 is a part hoisted on the mounting bracket 101, which is more likely to generate vibration, and the amplitude of the vibration is relatively large but the impact force of the vibration is not large. Therefore, in this application, the stiffness of the first shock-absorbing bushing 105 is set to be relatively smaller, which can achieve a better shock-absorbing effect. The second shock-absorbing bushing 108 is located between the mounting bracket 101 and the vehicle frame, and the amplitude of the generated vibration is relatively small but the impact force is relatively large. Therefore, in this application, the stiffness of the second shock-absorbing bushing 108 is set to be relatively larger, having a certain shock-absorbing effect and anti-impact ability.

[0039] That is to say, in this application, a suitable stiffness value is selected according to the use environment of the shock-absorbing bushing to ensure that the shock-absorbing bushing can effectively absorb and reduce vibration and impact, thereby improving the driving smoothness and comfort of the vehicle.

[0040] See Figure 4 As shown, in an alternative embodiment of this embodiment, the mounting bracket 101 is provided with at least three first mounting holes 109 arranged at intervals, and a first connecting component 102 is correspondingly mounted at the first mounting hole 109. The air pump 106 is mounted on the mounting bracket 101 through a plurality of first connecting components 102 to make the mounting effect more firm.

[0041] In an alternative embodiment of this embodiment, a circular first mounting groove 110 is provided in the circumferential direction of the first shock-absorbing bushing 105, and the hole wall of the first mounting hole 109 can be embedded in the first mounting groove 110 to mount and fix the first shock-absorbing bushing 105, making the mounting effect more firm and preventing the first shock-absorbing bushing 105 from disengaging from the first mounting hole 109.

[0042] In an alternative solution of this embodiment, on the side of the mounting bracket 101 facing away from the air pump 106, a recess 111 is provided circumferentially around each first mounting hole 109, so that the first connection assembly 102 mounted in the first mounting hole 109 sinks into the recess 111. On the side of the mounting bracket 101 facing away from the air pump 106, the end of the first connection assembly 102 will not protrude too much to affect the installation of other components.

[0043] It should be noted that, as Figure 2 shown, on the side of the mounting bracket 101 close to the air pump 106, a plurality of recesses 111 correspondingly form a plurality of protruding structures 112 on this side, and the ends of the plurality of protruding structures 112 are located on the same plane, so that the plurality of first connection assemblies 102 mounted there can be in contact with the mounting surface of the air pump 106, thereby making the installation of the air pump 106 more stable and reliable.

[0044] See Figure 4 shown, in an alternative solution of this embodiment, the mounting bracket 101 is provided with at least three second mounting holes 113 arranged at intervals, and second connection assemblies 103 are correspondingly mounted at the second mounting holes 113. The mounting bracket 101 is mounted on the vehicle frame through a plurality of second connection assemblies 103 to make the mounting effect more firm.

[0045] In an alternative solution of this embodiment, an annular second mounting groove 114 is provided circumferentially on the second damping bushing 108, and the hole wall of the second mounting hole 113 can be embedded in the second mounting groove 114 to fix the second damping bushing 108, which can make the mounting effect more firm and prevent the second damping bushing 108 from disengaging from the second mounting hole 113.

[0047] The air pump mounting structure in this Embodiment Two is an improvement based on the above embodiment, and the technical content disclosed in the above embodiment will not be described repeatedly. The content disclosed in the above embodiment also belongs to the content disclosed in this Embodiment Two.

[0048] In an alternative solution of this embodiment, a plurality of first connection assemblies 102 surround to form a first region, and a plurality of second connection assemblies 103 surround to form a second region, and the center of the first region is close to the center of the second region. When the mounting bracket 101 is mounted on the vehicle frame and the air pump 106 is mounted on the mounting bracket 101, the center of gravity of the air pump 106 can be close to or even overlap with the center of gravity of the mounting bracket 101, thereby making the installation of the air pump 106 more stable and reliable.
