[0044] See also Figure 1 , 8 -9. The present invention provides a connector 30 for connecting a first device 10 and a second device 20, and the connector 30 includes: a connecting component 31, a first vibration damper 32, a second vibration damper 33 and a support member 34; one end of the connecting component 31 can be connected to the first device 10, and the other end is provided with a limiting structure 3121; the first vibration damper 32 is sleeved on the connecting component 31, and is arranged close to the limiting structure 3121 and can be limited by the limiting structure 3121, and the outer side of the first vibration damper 32 is used to fit and limit the mounting hole 21 provided on the second device 20; the second vibration damper 33 is sleeved on the connecting component 31, and the second vibration damper 33 is located between the limiting structure 3121 and the end of the mounting hole 21 adjacent to the limiting structure 3121; the support member 34 is sleeved on the connecting component 31, and the projection of the support member 34 and the first vibration damper 32 along the radial direction of the connecting component 31 at least partially overlaps.

[0045] It should be noted that the connecting component 31 is a fastener connecting the first device 10 and the second device 20, such as a bolt, a screw, a stud with a nut, etc.; the limiting structure 3121 is a structure that can limit the first device 10 from being separated from the connecting component 31, such as the limiting structure 3121 is a protruding structure, or the limiting structure 3121 is a rod-shaped structure or a pancake-shaped structure vertically connected to the end of the connecting component 31; because the limiting structure 3121 can limit the first vibration damper 32 in the axial direction of the connecting component 31, it can prevent the second device 20 from driving the first vibration damper 32 to vibrate in the axial direction of the connecting component 31 and excessively deform, and can play a certain protective role on the first vibration damper 32; the first vibration damper 32 and the second The vibration dampers 33 are all made of elastic materials, such as rubber; the first vibration damper 32 is a rubber bushing, and the second vibration damper 33 is a rubber gasket; the connection component 31 and the first device 10 are welded or threaded or limitedly connected by bolts and nuts; the first vibration damper 32 is sleeved on one end of the connection component 31 with a limiting structure 3121, and the first vibration damper 32 sleeved on the connection component 31 is located at the mounting hole 21, so that the connection component 31 is connected to the second device 20, and the connection component 31 and the second device 20 are separated by the first vibration damper 32, which can reduce the vibration transmission between the first device 10 and the second device 20; and the outer surface of the first vibration damper 32 is adapted to fit with the inner wall of the mounting hole 21, so as to achieve the first vibration damper The purpose of limiting between the vibration member 32 and the mounting hole 21 is that a recess is provided on the outer surface of the first vibration damper 32, and a convex portion is provided on the inner wall of the mounting hole 21, and the convex portion and the recess are adapted to engage and limit; and the second vibration damper 33 is located between the limiting structure 3121 and the end of the mounting hole 21 adjacent to the limiting structure 3121, and the second vibration damper 33 can reduce vibration and noise between the second device 20 and the end of the connecting component 31, thereby improving the vibration reduction and noise reduction effect between the first device 10 and the second device 20; the support member 34 and the first vibration damper 32 are both sleeved on the connecting component 31, and the projections of the support member 34 and the first vibration damper 32 along the radial direction of the connecting component 31 at least partially overlap; generally, the length direction of the connecting component 31 The direction is the axial direction of the connecting component 32, and the direction perpendicular to the axial direction of the connecting component 32 is the radial direction of the connecting component. For example, the connecting component 31 includes a connecting member 312, and the connecting member 312 is a bolt. The axial direction and radial direction of the connecting component 31 can be determined by the axial direction and radial direction of the bolt. For the supporting member 34, the supporting member 34 is a metal member, such as an aluminum sleeve, a copper sleeve, an iron sleeve, or the supporting member 34 is a structure with a circular or polygonal cross section, or the supporting member 34 is a plurality of supporting columns uniformly embedded along the axial direction of the first vibration damper 32; the supporting member 34 is arranged on the inner side of the first vibration damper 32, or the supporting member 34 is arranged on the outer side of the first vibration damper 32, or the supporting member 34 is arranged inside the first vibration damper 32;Since the support member 34 is disposed between the connecting component 31 and the first vibration damper 32, on the one hand, along the axial direction of the connecting component 31, within the length region of the support member 34, the first vibration damper 32 will no longer be compressed, so that the support member 34 can play a certain protective role on the first vibration damper 32 in the axial direction of the connecting component 31; on the other hand, if the support member 34 is sleeve-shaped, and sleeve-shaped support members 34 are disposed on the inner and outer sides of the first vibration damper 32, when the second device 20 or the first device 10 vibrates along the radial direction of the connecting component 31, the first vibration damper 32 will be subjected to tensile and compressive loads alternately, thereby having a greater impact on the durability of the first vibration damper 32, resulting in a shorter service life of the first vibration damper 32; and In this case, the support member 34 is arranged inside the first vibration damper 32 or in the first vibration damper 32, instead of arranging two sleeve-shaped support members 34, so that the first vibration damper 32 of this case can be prevented from being subjected to alternating tensile and compressive stresses that affect the service life of the first vibration damper 32, and the arrangement of parts can be reduced, saving costs; and since the first vibration damper 32 is only subjected to compressive stress in the radial direction of the connecting component 31, and is not subjected to alternating tensile and compressive loads in the radial direction, it will be beneficial for the durability and vibration isolation performance of the first vibration damper 32 to be maintained for a long time, and thus the vibration transmission between the first device 10 and the second device 20 can be reduced or isolated for a relatively long time, and the noise generated by the vibration at the connection between the first device 10 and the second device 20 can be reduced. ;

[0046] As one of the embodiments of the present case, the first vibration damper 32 and the mounting hole 21 are in interference fit, which can improve the connection firmness between the first vibration damper 32 and the second device 20, thereby improving the connection stability of the connector 30.

[0047] See also Figure 1 and 2 As one of the embodiments of this case, the connecting component 31 includes:

[0048] A connecting member 312, one end of which can be connected to the first device 10, and the other end of which has a limiting structure 3121;

[0049] The limiting gasket 313 is sleeved and limited at one end of the connecting member 312 having the limiting structure 3121 .

[0050] It should be noted that the limiting gasket 313 can be integrally connected to the connecting member 312, and the limiting gasket 313 can also be detachably connected to the connecting member 312; when the connecting member 312 is a bolt, the limiting structure 3121 is the head of the bolt, and the limiting gasket 313 is limited by the head of the bolt. By setting the limiting gasket 313, the first vibration damping member 32 and the second vibration damping member 33 close to the limiting structure 3121 can be limited, thereby avoiding or reducing the first vibration damping member The first vibration damper 32 and the second vibration damper 33 are damaged by excessive pulling and deformation, and the support member 34 can prevent the first vibration damper 32 and the second vibration damper 33 from being overly compressed in the axial direction, so that the limiting gasket 313 cooperates with the support member 34 to achieve multi-directional protection for the first vibration damper 32 and the second vibration damper 33, thereby avoiding excessive deformation of the first vibration damper 32 and the second vibration damper 33, and further improving the vibration isolation performance and durability of the rubber bushing formed by the first vibration damper 32 and the second vibration damper 33.

[0051] See also Figure 2 Or 3, 8-9, as one of the embodiments of the present case, the first vibration damping member 32 and the second vibration damping member 33 are formed as one piece.

[0052] It should be noted that by molding the first vibration damper 32 and the second vibration damper 33 as one piece, on the one hand, it is convenient to manufacture the first vibration damper 32 and the second vibration damper 33; at the same time, the first vibration damper 32 and the second vibration damper 33 are molded as one piece, the cumulative error of the dimension chain is small, and the product quality is better; on the other hand, the first vibration damper 32 can mainly isolate the vibration of the second device 20 in the radial direction, and the second vibration damper 33 can mainly isolate the vibration of the second device 20 in the axial direction. The first vibration damper 32 and the second vibration damper 33 are molded as one piece, which can better realize the soft connection between the second device 20 and the first device 10.

[0053] See also Figure 2 Or 3, as one of the embodiments of the present case, the support member 34 and the first vibration damping member 32 and the second vibration damping member 33 are vulcanized and formed into one piece.

[0054] It should be noted that the first vibration damper 32, the second vibration damper 33 and the support member 34 are formed as one body, which further reduces the cumulative error of the dimension chain, improves product quality, and reduces the connection error between the first device 10 and the second device 20, thereby avoiding the problem of large vibration caused by excessive gap at the connection between the first device 10 and the second device 20, thereby reducing the vibration and noise between the first device 10 and the second device 20; at the same time, it is also convenient for the installation of the overall support member 34, the first vibration damper 32, and the second vibration damper 33.

[0055] See also Figure 3 , 9As one of the embodiments of the present case, the support member 34 is a sleeve-shaped structure, and a third vibration damping member 35 is provided on the inner wall of the support member 34 .

[0056] It should be noted that, by providing the third vibration damper 35, it is possible to reduce or avoid the direct collision between the support member 34 and the connecting assembly 31 during use to generate noise and vibration, thereby further achieving the purpose of vibration isolation and noise reduction; the third vibration damper 35 can be vulcanized into one with the first vibration damper 32, or it may not be vulcanized into one, but when the third vibration damper 35 is vulcanized into one with the first vibration damper 32, it will be convenient to install the first vibration damper 32, the second vibration damper 33, the third vibration damper 35 and the support member 34 as a whole.

[0057] See also Figure 3 As one of the embodiments of the present case, the second vibration damper 33 is arranged obliquely along the radial direction of the first vibration damper 32, and there is a gap between the second vibration damper 33 and the limiting structure 3121 and / or between the second vibration damper 33 and the side wall of one end of the mounting hole 21 close to the second vibration damper 33.

[0058] It should be noted that when the first device 10 or the second device 20 vibrates and shakes, the second vibration damper 33 is tilted along the radial direction of the first vibration damper 32, and a gap is provided between the second vibration damper 33 and the limiting structure 3121 and / or between the second vibration damper 33 and the side wall of one end of the mounting hole 21 close to the second vibration damper 33, thereby increasing the axial deformation range of the second vibration damper 33, thereby further increasing the vibration isolation and noise reduction effect of the second vibration damper 33 between the second device 20 and the connecting assembly 31.

[0059] See also Figure 4 As one of the embodiments of the present case, the second vibration damper 33 includes vibration damping strips 331 uniformly arranged along the radial direction of the first vibration damper 32; the ends of the adjacent vibration damping strips 331 away from the axial direction of the connecting component 31 have a certain gap, so that after the second vibration damper 33 is deformed along the axial direction of the connecting component 31, after the second device 20 presses the second vibration damper 33 against the limiting gasket 313, the second vibration damper 33 can be deformed along the axial direction of the connecting component 31, that is, the adjacent vibration damping strips 331 are compressed, thinned and close to each other, so that the second device 20 is subjected to multiple vibration attenuation when the connecting component 31 vibrates in the axial direction, and the multiple vibration damping effects are superimposed, thereby further reducing the vibration amount and vibration noise of the second device 20 in the axial direction of the connecting component 31.

[0060] See also Figure 3 , as one of the embodiments of the present case, the first vibration damping member 32 includes: a body 321;

[0061] A first extension portion 322, arranged along the radial direction of the body 321 and connected to the body 321;

[0062] The second extension portion 323 is arranged along the axial direction of the main body 321 and connected to the end of the first extension portion 322 away from the main body 321; the maximum width of the lower end of the second extension portion 323 along the radial direction of the main body 321 is greater than the minimum aperture of the mounting hole 21, and there is a gap between the second extension portion 323 and the main body 321.

[0063] It should be noted that the body 321 is sleeve-shaped, and the first extension portion 322 and the second extension portion 323 are provided so that there is a certain gap between the second extension portion 323 connected to the mounting hole 21 of the second device 20 and the body 321, so that the small vibration of the second device 20 along the axial direction of the connecting component 31 will not be directly transmitted to the support member 34 and the connecting component 31, but will first be attenuated by the first extension portion 322, thereby greatly reducing the vibration transmission between the first device 10 and the second device 20; for example, the left hand holds a working micro-engine, and the right hand holds a hanging rope, and the hanging rope is connected to a micro-engine that is also working. At this time, the left hand can feel a large vibration of the micro-engine, and the right hand can feel a negligible vibration of the micro-engine. The first extension portion 322 and the second extension portion 323 provided in this case are equivalent to the hanging rope to a certain extent. Therefore, through the flexible connection between the second device 20 and the connecting component 31, the vibration transmission between the second device 20 and the first device 10 can be greatly reduced.

[0064] See also Figure 3 As one of the embodiments of the present case, one end of the second extension portion 323 is connected to the first extension portion 322, and the other end of the second extension portion 323 extends along the axial direction of the main body 321 toward one end away from the second vibration damping member 33; a recess is provided in the radial direction of the second extension portion 323, and a convex portion is provided on the inner wall of the mounting hole 21, and the convex portion is adapted to engage with the recess for limiting positioning.

[0065] It should be noted that the second extension portion 323 and the mounting hole 21 may be an interference fit; the recessed portion is a ring-shaped structure arranged along the radial direction of the second extension portion 323, which can increase the limiting effect of the second extension portion 323 on the convex portion arranged on the inner wall of the mounting hole 21 in the axial direction and the radial direction of the first vibration damper 32, and can improve the connection limiting effect between the first vibration damper 32 and the mounting hole 21; taking the end of the connector 30 having the limiting structure 3121 as the upper end, by arranging the convex portion at the end of the mounting hole 21 away from the limiting structure 3121, and the recessed portion is arranged at the end of the second extension portion 323 away from the first extension portion 322, the first vibration damper 3 2 and the mounting hole 21 are both structures with a small upper end and a large lower end, and the lower end of the second extension part 323 is larger than the aperture of the lower end of the mounting hole 21, which can prevent the lower end of the mounting hole 21 from being separated from the lower end of the second extension part 323; and because the second extension part 323 has a larger degree of freedom of movement at one end away from the first extension part 322, it is convenient for the first vibration damper 32 to be installed in the mounting hole 21, and it is beneficial for the first vibration damper 32 to support the lower end of the mounting hole 21 and limit the overall mounting hole 21; the support member 34 can be arranged between the body 321 and the connecting member 312, and the support member 34 can also be integrally formed with the body 312, which is beneficial to the manufacture of the connector 30.

[0066] See also Figure 5-9 The present invention also provides a compressor, comprising:

[0067] The compressor body 40 is mounted on a subframe cross member 50 of the vehicle;

[0068] A first mounting bracket 60 is disposed between the compressor body 40 and the sub-frame cross beam 50, and the first mounting bracket 60 and the sub-frame cross beam 50 and / or the first mounting bracket 60 and the compressor body 40 are connected via the connector 30;

[0069] Furthermore, the mounting point between the first mounting bracket 60 and the compressor body 40 and the mounting point between the first mounting bracket 60 and the sub-frame cross beam 50 are staggered.

[0070] It should be noted that, due to the excitation of the high speed of the compressor body 40, the first mounting bracket 60 needs to have a high modal frequency to avoid resonance with the excitation frequency of the compressor body 40 as much as possible; and since the rubber material used in the general rubber vibration reduction has a low stiffness, the vibration noise caused by high-frequency excitation is isolated; therefore, the first mounting bracket 60 of this case adopts a "mouth"-shaped structure with a high modal frequency, which can do a good job of frequency avoidance relative to the excitation of the compressor body 40, and can do a good job of noise reduction and shock absorption. At the same time, the first mounting bracket 60 is topologically optimized, with a simple structure, light weight and low cost;

[0071] The first mounting bracket 60 is connected to the sub-frame cross beam 50 by fasteners or welding or by a connector 30, or the first mounting bracket 60 is connected to the compressor body 40 by fasteners or welding or by a connector 30; or the first mounting bracket 60 and the sub-frame cross beam 50, as well as the first mounting bracket 60 and the compressor body 40 are both connected by a connector 30; when the connector 30 is used for connection, the vibration transmission between the first device 10 and the second device 20 connected by the connector 30 can be reduced, and the noise at the connection can be reduced; when the first mounting bracket 60 and the compressor body 40, as well as the first mounting bracket 60 and the sub-frame cross beam 50 are both connected by the connector 30, two-stage vibration reduction between the compressor body 40 and the sub-frame cross beam 50 can be achieved, and the vibration isolation and noise reduction effect is greatly reduced.

[0072] See also Figure 5-9 , the present invention also provides a compressor, comprising: a compressor body 40;

[0073] A first mounting bracket 60 is rigidly connected to the compressor body 40 or connected via the connector 30;

[0074] A second mounting bracket 70 is used to connect to the subframe cross beam 50 of the vehicle, and the second mounting bracket 70 and the first mounting bracket 60, and the second mounting bracket 70 and the subframe cross beam 50 are connected through the connector 30;

[0075] Furthermore, the mounting point between the second mounting bracket 70 and the first mounting bracket 60 and the mounting point between the second mounting bracket 70 and the sub-frame cross beam 50 are staggered.

[0076] It should be noted that the first mounting bracket 60 and the compressor body 40 are connected by fasteners or welding or by the connector 30; the fasteners are bolts or screws; when the first mounting bracket 60 and the compressor body 40 are connected by the connector 30, the first mounting bracket 60 and the second mounting bracket 70, and the second mounting bracket 70 and the subframe cross beam 50 of the vehicle are also connected by the connector 30, so that three-level vibration reduction can be achieved, which can greatly improve the vibration reduction and noise reduction effect; of course, if too many mounting brackets are arranged between the compressor body 40 and the subframe cross beam 50, such as three mounting brackets or more mounting brackets, and connected by the connector 30, although vibration reduction and noise reduction can be achieved to a certain extent, the manufacturing cost of the compressor will increase due to the excessive number of mounting brackets, and the volume of the entire compressor will increase, resulting in a larger swing amplitude of the compressor body 40 when in use, which makes the overall vibration reduction of the compressor in use. On the contrary, the vibration reduction effect is reduced; therefore, when installing the compressor body 40, it is more appropriate to use one or two mounting brackets. The compressor body 40 and the subframe cross beam 50 are connected, and two layers of vibration reduction or three layers of vibration reduction are used for better effect. Therefore, a first mounting bracket 60 or a first mounting bracket 60 and a second mounting bracket 70 are selected on the compressor, which is both low-cost and can achieve better vibration reduction and noise reduction effects; of course, the present case is not limited to setting four layers of vibration reduction or five layers of vibration reduction or more layers of vibration reduction, nor is it limited to setting four or more mounting brackets; the present case makes the first mounting bracket 60 and the second mounting bracket 70 as a whole separately, and connects them through the connector 30, thereby avoiding deformation of the rubber bushing caused by the influence of the cumulative error of the assembly / dimensional chain, thereby causing the durability of the rubber bushing to deteriorate; the first vibration damper 32 and the second vibration damper 33 are a whole and form a rubber bushing, the rubber bushing is not easily affected by the cumulative dimensional chain error, the product quality is stable, and the durability is good.

[0077] Among them, the first device 10 is one of the compressor body 40, the subframe cross beam 50, the first mounting bracket 60 or the second mounting bracket 70, and the second device 20 is the other of the first mounting bracket 60, the second mounting bracket 70, the compressor body 40 or the subframe cross beam 50; the connector 30 is installed on the compressor body 40 or the subframe cross beam 50, or the first mounting bracket 60 or the second mounting bracket 70 according to actual needs, or is installed on one or more of the compressor body 40, the subframe cross beam 50, the first mounting bracket 60, and the second mounting bracket 70 at the same time.

[0078] Furthermore, a connection point 61 is provided on the first mounting bracket 60 and / or the second mounting bracket 70; the structure of the connection point 61 may be the same as or different from the structure of the mounting hole 21 according to actual needs.

[0079] Furthermore, in this case, by staggering the mounting points between the second mounting bracket 70 and the first mounting bracket 60 and between the second mounting bracket 70 and the sub-frame cross beam 50, it is possible to avoid the mounting points being too concentrated. The mounting points are mounting holes 21 or connection points 61; the mounting points are generally arranged at locations with larger vibration on the first mounting bracket 60, the second mounting bracket 70, the compressor body 40, and the sub-frame cross beam 50, so that the connector 30 can exert the maximum vibration reduction effect.

[0080] The present invention also provides a vehicle, comprising any one of the above-mentioned compressors.

[0081] It should be noted that, since the compressor includes the connector 30 , the vehicle has the advantages of the connector 30 .

[0082] In summary, the present invention effectively overcomes some practical problems in the prior art and thus has high utilization value and use significance.
