Description

Technical Field

[0001] This invention relates to a vibration damping mechanism and a vehicle equipped with the vibration damping mechanism, wherein the vibration damping mechanism has a better vibration damping effect. Background Technology

[0002] In many technical fields, vibration damping mechanisms are needed to reduce vibrations in equipment to enhance user experience. Taking the automotive industry as an example, the compressor in a car generates significant vibrations, thus requiring a vibration damping mechanism. Chinese Utility Model Patent No. CN203879703U discloses a compressor buffer mechanism for a four-wheeled recreational vehicle's air conditioning system. This mechanism includes a buffer plate between the compressor and its mounting base, a first buffer assembly between the compressor and the buffer plate to form a primary buffer for the compressor, and a second buffer assembly between the buffer plate and the mounting base to form a secondary buffer for the compressor. Because the buffer mechanism is entirely located between the compressor and its mounting base, although it provides two levels of vibration damping, it only effectively reduces vibrations in the vertical direction of the compressor and cannot effectively reduce vibrations in the rotational direction. Therefore, the damping effect of this mechanism is poor and cannot meet the increasingly demanding requirements of users for comfort.

[0003] Therefore, we hope to propose a new technical solution to meet the above requirements. Summary of the Invention

[0034] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts shall all fall within the protection scope of the present invention.

[0035] Reference Figures 1 to 3 , the present invention provides a vibration damping mechanism 100, which is used for, but not limited to, damping vibration of a compressor 200. The compressor 200 has a center of mass, which is generally understood in the art, that is, the mass center of the compressor 200. The compressor 200 has a rotating shaft (not shown), and the extending direction of the rotating shaft is S. Generally speaking, when the compressor 200 operates, it mainly generates vibration in two directions: vibration in the vertical direction V and vibration in the rotation direction R.

[0036] Continue reference Figures 1 to 3 , the vibration damping mechanism 100 includes a plurality of elastic elements 1, each of the elastic elements 1 has an elastic center, and the elastic center is generally understood in the art. The plurality of elastic centers are not all located in the same plane and together form a three-dimensional buffer space 10, the center of mass of the compressor 200 is located in the buffer space 10, that is, the buffer space 10 is used to accommodate the center of mass of the compressor 200. With this arrangement, the vibration damping mechanism 100 can effectively damp the vibration of the compressor 200 in the vertical direction V and also effectively damp the vibration of the compressor 200 in the rotation direction R, therefore, the vibration damping effect of the vibration damping mechanism 100 on the compressor 200 is greatly improved. The elastic element 1 is a rubber member or a spring. The plurality of elastic centers are all located on an edge of the buffer space 10. The buffer space 10 has a geometric center, and the center of mass completely coincides with the geometric center. The closer the center of mass of the compressor 200 is to the geometric center of the buffer space 10, the better the vibration damping effect on the compressor 200 is, and when the two completely coincide, the vibration damping effect is the best.

[0037] Reference Figures 1 to 4The vibration damping mechanism 100 includes a mounting base 3 and a bracket 2. The bracket 2 includes a first bracket 21 and a second bracket 22 assembled together. In this embodiment, the first bracket 21 is the upper bracket, and the second bracket 22 is the lower bracket. In other embodiments, the positional relationship between the first and second brackets 21 and 22 needs to be determined according to specific requirements. The compressor 200 is mounted on the first bracket 21, and the second bracket 22 is mounted on the mounting base 3. The mounting base 3 is mounted to a chassis such as a vehicle. The vibration damping mechanism 100 provides an elastic element 1 at the connection between the first bracket 21 and the second bracket 22 to form the first-level vibration damping of the compressor 200. The vibration damping mechanism 100 also provides an elastic element 1 at the connection between the second bracket 22 and the mounting base 3 to form the second-level vibration damping of the compressor 200. The elastic element 1 used to form the first-level vibration damping can be provided on the first bracket 21, or on the second bracket 22, or partially on the first bracket 21 and partially on the second bracket 22, as long as the vibration damping effect can be achieved. Similarly, the elastic element 1 used to form the secondary vibration damping can be disposed on the second bracket 22, on the mounting base 3, or partially on the second bracket 22 and partially on the mounting base 3. This arrangement allows the vibration damping mechanism 100 to form two levels of vibration damping. The vibration generated by the compressor 200 is first transmitted to the first bracket 21. When the vibration is transmitted to the elastic element 1 at the connection between the first bracket 21 and the second bracket 22, it is damped for the first time (first-level vibration damping). When the vibration is transmitted to the elastic element 1 at the connection between the second bracket 22 and the mounting base 3, it is damped for the second time (second-level vibration damping). The elastic element 1 used to form the secondary vibration damping can also filter vibration excitation generated on the ground. Of course, in other embodiments, the vibration damping mechanism 100 may not include the mounting base 3, and the second bracket 22 may be directly mounted to a chassis such as that of a vehicle. In this case, the elastic element 1 used to form the secondary vibration damping is disposed on the second bracket 22. In some other embodiments, the vibration damping mechanism 100 can also form three-level or even more levels of vibration damping. In this case, the second bracket 22 needs to be connected to another bracket. The elastic element 1 used to form the second-level vibration damping can be set on the second bracket 22, or on the other bracket, or partially set on the second bracket 22 and partially set on the other bracket.

[0038] Furthermore, the number of elastic elements 1 disposed in the secondary damping is greater than the number of elastic elements 1 disposed in the primary damping. (See reference...) Figure 3In this embodiment, the elastic element 1 is a rubber member, and a total of 7 elastic elements 1 are provided. The number of the elastic elements 1 used for the primary vibration damping is 3, and the number of the elastic elements 1 used for the secondary vibration damping is 4.

[0039] Referring to Figures 4 to 6 , the vibration damping mechanism 100 includes a buffer assembly 4 mounted on the support 2. In this embodiment, the buffer assembly 4 is configured to be mounted on the first support 21. Of course, in other embodiments, the buffer assembly 4 may also be configured to be mounted on the second support 22. The buffer structure used on the second support 22 in this embodiment will not be described in detail herein.

[0040] The buffer assembly 4 includes an outer ring 6 fixed to the support 2, the elastic element 1, a bolt 41, a limit washer 42, and an inner core 5 arranged inside the elastic element 1. The support 2 is provided with a mounting portion 23, the mounting portion 23 is provided with a mounting hole 20 open at both ends, and the buffer assembly 4 is fixed in the mounting hole 20 through the outer ring 6. It can be seen from the above description that in this embodiment, the mounting portion 23 is arranged on the first support 21. The outer ring 6 is preferably made of nylon material. The limit washer 42 is provided with a washer hole 420 for the bolt 41 to pass through, the inner core 5 is provided with a through hole 51 penetrating through both ends, the second support 22 is provided with a threaded hole 221, and the bolt 41 passes through the washer hole 420 and the through hole 51 and then fits with the threaded hole 221. Of course, in other embodiments, the bolt 41 may also be replaced with other fasteners.

[0041] Referring to Figures 3 to 6 , Figures 8 to 9, at least one elastic element (1) among the elastic elements (1) for forming the primary vibration damping comprises an inner layer (11) and an outer layer (12) extending perpendicular to the rotating shaft, and two connecting portions (13) arranged at an interval for connecting the outer layer (12) and the inner layer (11). In this embodiment, the buffer assembly (4) is fixed to the first bracket (21) via the outer ring (6), the elastic element (1) is a rubber member which is vulcanized and molded between the outer ring (6) and the inner core (5), the inner layer (11) is vulcanized and molded on the inner core (5), the outer layer (12) is vulcanized and molded on the outer ring (6), and the bolt (41) passes through the inner core (5) to be fixed to the second bracket (22). That is, the inner layer (11) is indirectly connected to the second bracket (22) via the inner core (5) and the bolt (41), and the outer layer (12) is indirectly connected to the first bracket (21) via the outer ring (6). Of course, in other embodiments, the buffer assembly (4) may not be provided with the outer ring (6), and the outer layer (12) may be directly vulcanized and molded on the first bracket (21); the buffer assembly (4) may not be provided with the inner core (5) and the bolt (41), and the inner layer (11) is directly vulcanized and molded on the second bracket (22). That is, the inner layer (11) is directly or indirectly connected to the second bracket (22), and the outer layer (12) is directly or indirectly connected to the first bracket (21). In some other embodiments, the outer layer (12) may also be directly or indirectly connected to the second bracket (22), and the inner layer (11) is directly or indirectly connected to the first bracket (21). The outer layer (12) and the inner layer (11) can move relatively, and in the extension direction S of the rotating shaft, the two connecting portions (13) are parallel to or coincide with the rotating shaft. Arranging at least one elastic element (1) in the primary vibration damping in the manner described above can effectively reduce the stiffness of the compressor 200 in the rotation direction R and improve the vibration isolation effect. Of course, in other embodiments, the elastic element (1) can also be fixed to the inner core (5) and / or the outer ring (6) by other materials and other methods.

[0042] See Figure 5 , Figures 7 to 9, the inner core 5 is provided with a limiting groove 52 arranged on one side of the through hole 51, and the limiting gasket 42 has a protruding portion 421 extending into the limiting groove 52. In the process of installing the bolt 41, the bolt 41 passes through the through hole 51 and is rotationally fixed to the second bracket 22. By providing the protruding portion 421 and the limiting groove 52, the limiting gasket 42 can be prevented from rotating along with the bolt. Preferably, the limiting groove 52 is smaller than the through hole 51. Preferably, the limiting groove 52 is in communication with the through hole 51. In this embodiment, there are two limiting grooves 52, which are respectively arranged on opposite sides of the through hole 51 and communicate with the through hole 51. Further, the protruding portion 421 and the limiting groove 52 are in interference fit. Generally, the bolt 41 is not installed before the compressor 200 is installed. By arranging the limiting groove 52 and the protruding portion 421 in interference fit, the limiting gasket 42 can be fixed on the inner core 5 without falling off even when the bolt 41 is not installed, which facilitates the transportation of the product.

[0043] Referring to Figures 7 to 10 , in a preferred embodiment, both ends of the inner core 5 protrude outward from the outer ring 6, and the limiting gasket 42 is provided with a laterally extending limiting portion 422. Preferably, the limiting portion 422 is V-shaped. When the inner layer 11 moves relatively to the outer layer 12 along with the inner core 5 by a large margin, the limiting portion 422 will directly or indirectly impact the outer ring 6, thereby preventing excessive displacement between the inner layer 11 and the outer layer 12. This arrangement can prevent the elastic element 1 from being damaged by excessive stretching. In this embodiment, the outer ring 6 has an end face 61, and the elastic element 1 is provided with an isolation buffer portion 14 at the end face 61. When a large relative movement occurs between the outer layer 12 and the inner layer 11, on the side of the limiting portion 422, the limiting portion 422 impacts the isolation buffer portion 14, and on the side of the second bracket 22, the second bracket 22 impacts the isolation buffer portion 14, and the isolation buffer portion 14 can improve the vibration damping effect.

[0044] Referring to Figures 7 to 9 , the isolation buffer portion 14 is provided as a multi-segment structure spaced apart from each other. Arranging the isolation buffer portion 14 into a multi-segment structure spaced apart from each other can make the stiffness of the elastic element 1 tend to be gentle, and improves vehicles with problems of shift shock or sudden acceleration and sudden deceleration.

[0045] Continuing to refer to Figures 7 to 9, the isolation buffer portion (14) is formed with a plurality of notches (141), and the end surface (61) is partially exposed through the notches (141). Since the isolation buffer portion (14) is provided at the end surface (61), the press-fitting tool cannot directly act on the outer ring (6) and can only act on the elastic isolation buffer portion (14), which makes it difficult to press-fit the buffer assembly (4) in place. By providing the notches (141), a large area of the outer ring (6) is exposed to the outside for direct action of the tool, such arrangement facilitates the press-fitting positioning of the buffer assembly (4) by the tool. Further, a portion of the elastic element (1) located in the notch (141) is flush with the end surface (61), which facilitates the placement of the tool and further facilitates the press-fitting positioning of the buffer assembly (4) by the tool. In this embodiment, the gaps between the multi-segment isolation buffer portions (14) form the notches (141). The position of the limiting portion (422) needs to correspond to the isolation buffer portion (14), and it is better to have as little corresponding portion with the notch (141) as possible, preferably no corresponding portion. The protruding portion (421) and the limiting groove (52) can ensure that this corresponding relationship does not change due to vibration.

[0046] Refer to Figure 5 and Figure 8 , the mounting hole (20) is provided with guide surfaces (201) at both ends thereof, the guide surfaces (201) are inclined surfaces or curved surfaces, the outer ring (6) has an outer surface (62) and is provided at both ends thereof with protruding portions (7) protruding from the outer surface (62) for interference fit with the guide surfaces (201). With such arrangement, reverse buckles are formed at both ends between the outer ring (6) and the mounting hole (20), which can prevent the buffer assembly (4) from detaching from the bracket (2) due to excessive vibration during use. Compared with the arrangement where an inclined or curved guide surface is provided on the outer ring (6) and a protruding portion for interference fit is provided on the bracket (2), the arrangement of the present invention can ensure the strength of the outer ring (6), facilitate the protection of the buffer assembly (4), and prolong the service life of the product. Further, the mounting portion (23) has two end surfaces (231), and the two end surfaces (61) of the outer ring (6) are flush with the two end surfaces (231) of the mounting portion (23). With such arrangement, the movable stroke of the limiting gasket (42) can be increased, which helps to improve the vibration damping effect. Preferably, the protruding portion (7) has a conical fitting portion, which has a stronger interference force.

[0047] Refer to Figure 11 , the present invention further provides a vibration damping mechanism according to another embodiment. The shape and structure of the vibration damping mechanism of the present embodiment are substantially the same as those of the vibration damping mechanism (100) in the above embodiment, the main difference is that the present embodiment provides another buffer assembly (4'). It should be noted that, except for the buffer assembly (4'), the reference numerals of other elements are the same as those in the above embodiment.

[0048] The buffer assembly 4' includes an outer ring 6' fixed to the bracket 2 and an elastic element 1' disposed within the outer ring 6'. The outer ring 6' has an end face 61' and an outer surface 62'. The elastic element 1' has an isolation buffer portion 14' extending out of the end face 61'. The outer ring 6' has a protrusion 7' ​​protruding from the outer surface 62', and the protrusion 7' ​​has an auxiliary support surface 631' for supporting the isolation buffer portion 14'. In a preferred embodiment, the protrusion 7' ​​has a ring structure, and the end face 61' is flush with the auxiliary support surface 631'. The isolation buffer portion 14' is used to prevent the outer ring 6' from directly colliding with other components, such as the limiting pad 42' or the second bracket 22, which helps to improve the vibration reduction effect. By providing the auxiliary support surface 631', a larger bearing area can be provided. This configuration allows the isolation buffer portion 14' to have a larger support area, and the isolation buffer portion 14' can be manufactured larger, resulting in better vibration damping of the compressor 200 by the vibration damping mechanism. In this embodiment, the protrusion 7' ​​is the same structure as the protrusion 7 that cooperates with the bracket 2 in the above embodiment. Of course, in other embodiments, they can also be configured as two separate structures.

[0049] The present invention also provides a vehicle (not shown) equipped with the compressor 200 and the vibration damping mechanism described in any of the preceding embodiments. The compressor 200 is installed between the first and second brackets 21 and 22, and the compressor 200 is at least partially located within the buffer space 10 such that the center of mass of the compressor 200 is located within the buffer space 10.

[0050] It is understood that the above embodiments of the present invention can be combined with each other to obtain more embodiments without conflict. The various specific technical features described in the above detailed embodiments can be combined in any suitable manner without contradiction.
