[0051] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0052] This utility model provides a connecting mechanism; please refer to [reference needed]. Figures 1 to 12The connecting mechanism includes a first mounting member 10, a second mounting member 20, a first connecting assembly 30, and a second connecting assembly 40. The first mounting member 10 is used to connect and fix to the vibrating component 200. The first connecting assembly 30 is connected to the first mounting member 10 and also to the second mounting member 20; the portion of the first connecting assembly 30 in contact with the second mounting member 20 is made of a flexible material. The second connecting assembly 40 is connected to the second mounting member 20 and is used to connect to the component to be assembled; the portion of the second connecting assembly 40 in contact with the second mounting member 20 is also made of a flexible material.

[0053] Since the parts of the first connecting component 30 and the second mounting component 20 that contact each other are made of flexible material, a two-stage vibration damping structure is formed through the first connecting component 30 and the second connecting component 40. Specifically, the flexible material portion of the first connecting component 30 reduces the vibration transmitted from the vibrating component 200 to the second mounting component 20, achieving a first-stage vibration damping function. Furthermore, the flexible material portion of the second connecting component 40 reduces the vibration transmitted from the second mounting component 20 to the component to be assembled, achieving a second-stage vibration damping function. This provides effective vibration damping for the vibrating component 200 and also achieves good noise reduction.

[0054] In this application, the vibrating component 200 may optionally be an air compressor.

[0055] Optionally, the vibrating component 200 is an on-board air compressor. For example, the vibrating component 200 is an air compressor for a sensor jet cleaning system in an autonomous vehicle.

[0056] In this application, optionally, the component to be assembled is a vehicle body. For example, the component to be assembled is the body of an autonomous vehicle.

[0057] By making the vibrating component 200 an air compressor and the component to be assembled a vehicle body, the connection mechanism of this application can effectively reduce or avoid the vibration generated by the air compressor during operation from being transmitted to the cabin through the vehicle body. This can achieve a better vibration reduction and noise reduction effect on the air compressor, thereby improving the riding experience and solving the problem of poor vibration reduction effect of vehicle-mounted air compressors in the prior art.

[0058] Optionally, the first mounting component 10 is a mounting bracket, and the second mounting component 20 is a mounting bracket.

[0059] It should be noted that the flexible materials mentioned in this application are all flexible vibration damping materials.

[0060] In this application, the first connecting component 30 includes an elastic element 31, the elastic extension direction of which is parallel or the same as the distribution direction of the first mounting member 10 and the second mounting member 20, so that at least part of the vibration generated by the vibrating member 200 can be counteracted in the elastic extension direction of the elastic element 31.

[0061] Specifically, the first direction is the direction along the distribution direction of the first mounting member 10 and the second mounting member 20, from the second mounting member 20 to the first mounting member 10. The second direction is the direction along the distribution direction of the first mounting member 10 and the second mounting member 20, from the first mounting member 10 to the second mounting member 20; that is, the second direction is opposite to the first direction.

[0062] Specifically, for the vibration generated by the vibrating component 200 along the first direction, and since the first mounting member 10 is fixedly connected to the vibrating component 200, the vibrating component 200 will drive the first mounting member 10 to vibrate along the first direction. At this time, the elastic expansion and contraction of the elastic member 31 can counteract at least part of the vibration in the first direction. For the vibration generated by the vibrating component 200 along the second direction, and since the first mounting member 10 is fixedly connected to the vibrating component 200, the vibrating component 200 will drive the first mounting member 10 to vibrate along the second direction. At this time, the elastic expansion and contraction of the elastic member 31 can counteract at least part of the vibration in the second direction. Therefore, the elastic expansion and contraction of the elastic member 31 can also dampen the vibration of the vibrating component 200.

[0065] Specifically, for the vibration generated by the vibrating component 200 along the first direction, the vibrating component 200 will drive the first mounting member 10 to vibrate along the first direction; since the fifth connecting part is connected to the second connecting part 33 and connected to the first mounting member 10, the first mounting member 10 will drive the second connecting part 33 to vibrate along the first direction through the fifth connecting part; since the first end of the elastic member 31 is connected to or abuts against the second connecting part 33, and the second end of the elastic member 31 is connected to or abuts against the first connecting part 32, when the second connecting part 33 vibrates along the first direction, it will cause compression or extension of the elastic member 31. At this time, the amount of compression or extension of the elastic member 31 is used to offset at least part of the vibration in the first direction.

[0066] For the vibration generated by the vibrating component 200 along the second direction, the vibrating component 200 will drive the first mounting member 10 to vibrate along the second direction; since the fifth connecting part is connected to the second connecting part 33 and connected to the first mounting member 10, the first mounting member 10 will drive the second connecting part 33 to vibrate along the second direction through the fifth connecting part; since the first end of the elastic member 31 is connected to or abuts against the second connecting part 33, and the second end of the elastic member 31 is connected to or abuts against the first connecting part 32, when the second connecting part 33 vibrates along the second direction, it will cause the elastic member 31 to extend or compress. At this time, the extension or compression of the elastic member 31 is used to counteract at least part of the vibration in the second direction.

[0067] Specifically, the portion of the first connecting part 32 that contacts the second mounting member 20 is made of a flexible material. Optionally, the entire first connecting part 32 may be made of a flexible material; for example, the first connecting part 32 may be made of rubber.

[0069] Optionally, along the distribution direction of the first mounting member 10 and the second mounting member 20, the first connecting portion 32 is located between the second connecting portion 33 and the first mounting member 10. In this way, when the second connecting portion 33 vibrates in the first direction, it will compress the elastic member 31; when the second connecting portion 33 vibrates in the second direction, it will stretch the elastic member 31.

[0071] By spacing the through member 34 from the wall of the connecting hole 321, the first connecting part 32 and the through member 34 do not interfere with each other when the first mounting member 10 drives the second connecting part 33 to vibrate in the first or second direction through the through member 34.

[0072] Specifically, the second end of the elastic member 31 is located inside the connecting hole 321, and the second end of the elastic member 31 is connected to or abuts against the hole wall of the connecting hole 321.

[0081] Optionally, when the elastic element 31 is a spring or an elastic sleeve, the second end of the second connecting part 33 passes through and is locked in the hole of the elastic element 31. At this time, the second end of the second connecting part 33 and the first end of the elastic element 31 are fixed relative to each other by the frictional force between the second connecting part 33 and the first end of the elastic element 31.

[0082] In this application, at least a portion of the second connecting portion 33 is made of a flexible material.

[0136] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0137] The connecting mechanism provided by this utility model includes a first mounting member 10, a second mounting member 20, a first connecting assembly 30, and a second connecting assembly 40. The first mounting member 10 is used to connect and fix with the vibrating component 200. The first connecting assembly 30 is connected to the first mounting member 10 and also to the second mounting member 20; the portion of the first connecting assembly 30 in contact with the second mounting member 20 is made of a flexible material. The second connecting assembly 40 is connected to the second mounting member 20 and is used to connect with the component to be assembled; the portion of the second connecting assembly 40 in contact with the second mounting member 20 is also made of a flexible material.

[0138] Since the parts of the first connecting component 30 and the second mounting component 20 that contact each other are made of flexible material, a two-stage vibration damping structure is formed through the first connecting component 30 and the second connecting component 40. Specifically, the flexible material portion of the first connecting component 30 reduces the vibration transmitted from the vibrating component 200 to the second mounting component 20, achieving a first-stage vibration damping function. Furthermore, the flexible material portion of the second connecting component 40 reduces the vibration transmitted from the second mounting component 20 to the component to be assembled, achieving a second-stage vibration damping function. This provides effective vibration damping for the vibrating component 200 and also achieves good noise reduction.

[0139] The first connecting assembly 30 includes an elastic element 31, the elastic extension direction of which is parallel or the same as the distribution direction of the first mounting member 10 and the second mounting member 20, so that at least part of the vibration generated by the vibrating member 200 can be counteracted in the elastic extension direction of the elastic element 31.

[0140] By making the vibrating component 200 an air compressor and the component to be assembled a vehicle body, the connection mechanism of this application can effectively reduce or avoid the vibration generated by the air compressor during operation from being transmitted to the cabin through the vehicle body. This can achieve a better vibration reduction and noise reduction effect on the air compressor, thereby improving the riding experience and solving the problem of poor vibration reduction effect of vehicle-mounted air compressors in the prior art.

[0141] In addition, the connection mechanism of this application can also eliminate the transmission of vibrations generated by the operation of other automotive components to the air compressor, thus preventing mechanical damage to the air compressor body.
