Decoupling assembly, suspension and vehicle

Abstract

The utility model relates to a decoupling assembly, a suspension and a vehicle. The decoupling assembly comprises a base, a first cover plate, a second cover plate and a decoupling film. The base and the first cover plate are connected and enclosed to form an accommodating cavity and a first flow channel which are arranged at an interval; the second cover plate is located on the side, away from the base, of the first cover plate and can be close to or away from the first cover plate. When the second cover plate is close to the first cover plate, the second cover plate can abut against the first cover plate and define a second flow channel, and the second flow channel communicates with the first flow channel. In the decoupling assembly, the first fluid chamber and the second fluid chamber of the suspension main body can be communicated through the first flow channel, the first fluid chamber and the second fluid chamber can also be communicated through the combination of the first flow channel and the second flow channel (the combination of the first flow channel and the second flow channel forms the second fluid channel), and when larger amplitude needs to be buffered, the first fluid channel and the second fluid channel are separated from each other. The second cover plate can be driven to move, so that the length of the flow channel is increased (the length of the second fluid channel is larger than that of the first flow channel), and larger damping can be generated.

Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle shock absorption, and particularly relates to a decoupling component, a mount and a vehicle. Background Art

[0002] As Figure 1 shown in the figure, a conventional mount 100a includes a mount body 10a and a decoupling component 20a. The mount body 10a has a liquid storage cavity. The decoupling component 20a is arranged in the liquid storage cavity and divides the liquid storage cavity into a first liquid chamber 11a and a second liquid chamber 12a. During use, the liquid in the first liquid chamber 11a can be exchanged with the liquid in the second liquid chamber 12a.

[0003] Specifically, the mount body 10a includes a support arm 1a, a rubber main spring 2a, a lower skeleton 3a, a leather cup 4a, a leather cup pressing ring 5a and an outer bracket 6a; the decoupling component 20a includes a cover plate 7a, a decoupling membrane 8a and a base 9a. The support arm 1a and the lower skeleton 3a are respectively connected to the upper and lower ends of the rubber main spring 2a. The outer bracket 6a is connected to the lower skeleton 3a, and the outer bracket 6a presses the cover plate 7a, the decoupling membrane 8a, the base 9a, the leather cup 4a and the leather cup pressing ring 5a on the lower skeleton 3a. Among them, the leather cup 4a and the rubber main spring 2a enclose to form the liquid storage cavity of the mount body 10a.

[0004] The cover plate 7a and the base 9a enclose to form a receiving cavity and a flow channel, and the receiving cavity and the flow channel are arranged at intervals. The decoupling membrane 8a is located in the receiving cavity and can vibrate up and down between them. When the mount 100a is in small-amplitude vibration, at this time, the liquid in the flow channel hardly flows, and the decoupling membrane 8a generates a small-amplitude vibration between the cover plate 7a and the base 9a, stirring the surrounding liquid, which plays a role in reducing the dynamic stiffness of the mount 100a.

[0005] When the mount 100a is in large-amplitude vibration, at this time, the liquid pushes the decoupling membrane 8a to move with a large displacement, and then closely adheres to the lower surface of the cover plate 7a or the upper surface of the base 9a, and blocks the liquid holes of the cover plate 7a or the liquid holes of the base 9a. At this time, the liquid in the first liquid chamber 11a and the second liquid chamber 12a circulates with each other through the flow channel and generates a large damping, which plays a role in quickly attenuating the large-amplitude vibration of the power assembly.

[0006] However, in the existing mount, the length of the flow channel of its decoupling component is fixed, and it is difficult to achieve a larger damping. Summary of the Utility Model

[0043] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0044] As Figure 2 shown, in one embodiment, the mount 100 includes a mount body 10 and a decoupling component 20. Among them, the mount body 10 has a liquid storage cavity 101, and the decoupling component 20 is arranged in the liquid storage cavity 101 for dividing the liquid storage cavity 101 into a first liquid chamber 102 and a second liquid chamber 103, and the liquids in the first liquid chamber 102 and the second liquid chamber 103 can be exchanged through the decoupling component 20.

[0045] "The liquids in the first liquid chamber 102 and the second liquid chamber 103 can be exchanged through the decoupling component 20" means that the liquid in the first liquid chamber 102 can flow through the decoupling component 20 to the second liquid chamber 103, and at the same time, the liquid in the second liquid chamber 103 can flow through the decoupling component 20 to the first liquid chamber 102.

[0046] like Figure 2 As shown, in one embodiment, the suspension body 10 includes a main spring 1 and a leather cup 2, and the main spring 1 and the leather cup 2 are connected and enclosed to form a liquid storage chamber 101. Among them, the main spring 1 can be a rubber main spring.

[0047] In addition, the suspension body 10 further includes a support arm 3 , a lower frame 4 and an outer bracket 5 ; wherein the support arm 3 and the lower frame 4 are both connected to the main spring 1 , and the outer bracket 5 is connected to the lower frame 4 .

[0048] like Figure 2 As shown, the lower frame 4 is provided with a first folded edge 41, and the first folded edge 41 presses the leather cup 2 onto the decoupling assembly 20, and at the same time, the leather cup 2 presses the decoupling assembly 20 onto the main spring 1. That is, in this embodiment, the leather cup 2 and the decoupling assembly 20 are actually pressed onto the main spring 1 by the first folded edge 41, thereby realizing the connection between the leather cup 2 and the main spring 1, and realizing the connection between the decoupling assembly 20 and the suspension body 10.

[0049] like Figure 2 As shown, the outer bracket 5 includes a first shell 51 and a second shell 52, and the first shell 51 and the second shell 52 are connected to form a cover structure, and the suspension body 10 is arranged in the cover structure. The cover structure is provided with a corresponding avoidance space so that the bracket 3 can extend out of the cover structure. In addition, the lower frame 4 also includes a second folded edge 42, and the second folded edge 42 is located between the folded edge of the first shell 51 and the folded edge of the second shell 52, and the three can be pressed together by bolts or the like. When in use, the outer bracket 5 is connected to the subframe or the vehicle body, and the bracket 3 is connected to the powertrain.

[0050] Of course, the structures of the main spring 1, the leather cup 2, the support arm 3, the lower frame 4 and the outer bracket 5 in the suspension body 10 can be existing technologies, and the assembly method of the five can also adopt the existing design method, and this embodiment will not be explained in detail here.

[0051] like Figures 2 to 4 As shown, in one embodiment, the decoupling assembly 20 includes a base 6, a first cover plate 7, a second cover plate 8 and a decoupling membrane 91; the base 6 and the first cover plate 7 are connected to enclose a mutually spaced accommodating cavity and a first flow channel, that is, the base 6 and the first cover plate 7 are connected to enclose a accommodating cavity and a first flow channel, and the accommodating cavity and the first flow channel are spaced apart; the second cover plate 8 is located on the side of the first cover plate 7 away from the base 6, and can approach or move away from the first cover plate 7; when the second cover plate 8 approaches the first cover plate 7, it can contact with the first cover plate 7 and enclose to form a second flow channel.

[0052] In addition, if Figure 3 and Figure 4As shown, the base 6 is provided with a first through hole 61 and a second through hole 62 spaced apart from each other. The first cover plate 7 is provided with a third through hole 71 and a fourth through hole 72 spaced apart from each other. The second cover plate 8 is provided with a fifth through hole 81. The first through hole 61, the second through hole 62, the third through hole 71, the fourth through hole 72, and the fifth through hole 81 all extend along the arrangement direction of the first cover plate 7 and the base 6 (this direction is defined as the first direction). That is, the first through hole 61 and the second through hole 62 penetrate the base 6 along the first direction, the third through hole 71 and the fourth through hole 72 penetrate the first cover plate 7 along the first direction, and the fifth through hole 81 penetrates the second cover plate 8 along the first direction. In Figures 2 to 4 , the first direction is parallel to the X-axis.

[0053] In one scenario, the first direction is the vertical direction, and the base 6, the first cover plate 7, and the second cover plate 8 are arranged in sequence from bottom to top.

[0054] In addition, the first through hole 61 and the third through hole 71 communicate with the accommodation chamber. The first flow channel includes the second through hole 62 and the fourth through hole 72, and the second flow channel includes the fourth through hole 72 and the fifth through hole 81. The decoupling film 91 is disposed in the accommodation chamber and can seal the first through hole 61 and can also seal the third through hole 71. Specifically, the decoupling film 91 can selectively seal one of the first through hole 61 and the third through hole 71. Among them, when the decoupling film 91 is close to the base 6, it can seal the first through hole 61, and when the decoupling film 91 is close to the first cover plate 7, it can seal the third through hole 71.

[0055] The first liquid chamber 102 is located on the side of the base 6 away from the first cover plate 7, and the second liquid chamber 103 is located on the side of the first cover plate 7 away from the base 6. The accommodation chamber communicates with the first liquid chamber 102 through the first through hole 61, and the accommodation chamber communicates with the second liquid chamber 103 through the third through hole 71. The first flow channel communicates the first liquid chamber 102 and the second liquid chamber 103. In addition, the first through hole 61, the gap between the decoupling film 91 and the cavity wall of the accommodation chamber, and the third through hole 71 communicate to form a first fluid channel. When the second cover plate 8 and the first cover plate 7 enclose to form a second flow channel, the first flow channel and the second flow channel communicate to form a second fluid channel. At this time, the first liquid chamber 102 and the second liquid chamber 103 communicate through the second fluid channel.

[0056] During operation, the liquid in the first liquid chamber 102 can flow to the second liquid chamber 103 through the first flow channel, and the liquid in the second liquid chamber 103 can flow to the first liquid chamber 102 through the first flow channel. The liquid in the first liquid chamber 102 can also flow to the second liquid chamber 103 through the first fluid channel, and the liquid in the second liquid chamber 103 can flow to the first liquid chamber 102 through the first fluid channel. The liquid in the first liquid chamber 102 can also flow to the second liquid chamber 103 through the second fluid channel, and the liquid in the second liquid chamber 103 can flow to the first liquid chamber 102 through the second fluid channel.

[0057] During operation, the decoupling component 20 has two states, namely: State 1, the second cover plate 8 does not contact the first cover plate 7. At this time, the two are arranged at intervals, and the decoupling component 20 does not have a second flow channel; State 2, the second cover plate 8 contacts the first cover plate 7. At this time, the decoupling component 20 has a second flow channel.

[0058] When the vehicle is idling or driving on a flat road surface, the amplitude of the mount 100 is very small and in a low-amplitude state. At this time, the decoupling component 20 is in State 1. In this scenario, the liquid in the first flow channel hardly flows. The decoupling membrane 91 generates a small up-and-down vibration, agitating the surrounding liquid, which plays a role in reducing the dynamic stiffness of the mount 100. In this scenario, the liquid in the first liquid chamber 102 and the second liquid chamber 103 also flows through the first fluid channel.

[0059] When the vehicle is driving on a slightly rough road surface, the amplitude of the mount 100 is relatively large and in a medium-amplitude state. At this time, the decoupling component 20 is in State 1. In this scenario, the main spring 1 deforms and pushes the liquid to flow. The liquid in the first liquid chamber 102 and the second liquid chamber 103 flows through the first flow channel (the flow route is shown by Figure 4 the dotted line), and a large damping is generated to attenuate the medium-amplitude vibration of the powertrain. In this scenario, only the first flow channel generates damping, and the dynamic stiffness of the mount 100 increases but remains at a relatively low level, which can balance the NVH performance.

[0060] When the vehicle is driving on a rocky road or passing over a speed bump and other large-amplitude working conditions, the amplitude of the mount 100 is very large and in a large-amplitude state. When the powertrain jumps downward, a large amount of damping liquid in the second liquid chamber 103 flows from the first flow channel to the first liquid chamber 102. At this time, the second cover plate 8 can be close to and contact the first cover plate 7 to form a second flow channel. At this time, the first liquid chamber 102 and the second liquid chamber 103 exchange liquid through the second fluid channel (the flow route is shown by Figure 3 the dotted line). In this scenario, the damping of the mount 100 is generated jointly by the first flow channel and the second flow channel, and the damping reaches the maximum value, quickly attenuating the large-amplitude vibration of the powertrain and improving the ride comfort of the vehicle.

[0061] That is, in this embodiment, in the decoupling component 20, the first liquid chamber 102 and the second liquid chamber 103 can be connected through the first flow channel, or the first liquid chamber 102 and the second liquid chamber 103 can be connected through the second fluid channel. Both the first flow channel and the second fluid channel are flow channels of the decoupling component 20. When a larger amplitude needs to be buffered, the second cover plate 8 can move to increase the length of the flow channel (the length of the second fluid channel is greater than that of the first flow channel), thereby generating a greater damping force. Additionally, the arrangement of this embodiment can increase the length of the flow channel without increasing the size of the decoupling component in the radial direction (i.e., perpendicular to the first direction), so that the size of the mount 100 will not be increased. Moreover, in the state of small amplitude, the second cover plate 8 is spaced apart from the first cover plate 7. At this time, the second cover plate 8 will not affect the flow of liquid between the two liquid chambers through the first fluid channel, enabling the mount 100 to have better dynamic stiffness.

[0062] As Figure 4 shown, in one embodiment, the base 6 is provided with a receiving hole 63, and the first cover plate 7 closes the receiving hole 63 to form a receiving cavity.

[0063] Among them, the receiving hole 63 can be provided on the surface of the base 6 close to the first cover plate 7, that is, the receiving hole 63 is provided on the upper surface of the base 6. The first cover plate 7 can abut against the upper surface of the base 6 and close the opening (defined as the first opening) formed by the receiving hole 63 on the upper surface of the base 6, thereby realizing the closure of the receiving hole 63.

[0064] The first cover plate 7 closing the first opening may mean that in the orthographic projection on a plane perpendicular to the first direction, the projection of the first opening is completely located within the projection of the lower surface of the first cover plate 7, and a part of the projection of the first opening coincides with the projection of the opening formed by the third through hole 71 on the lower surface of the first cover plate 7.

[0065] In addition, the upper surface of the base 6 can be a plane, and the surface of the first cover plate 7 close to the base 6 (i.e., the lower surface of the first cover plate 7) can also be a plane. The upper surface of the base 6 and the lower surface of the first cover plate 7 can overlap.

[0066] As Figure 4 shown, in one embodiment, the base 6 is provided with a receiving groove 64, the first cover plate 7 closes the receiving groove 64, and both the second through hole 62 and the fourth through hole 72 communicate with the receiving groove 64 to form a first flow channel. That is, the first flow channel is composed of the second through hole 62, the fourth through hole 72, and the receiving groove 64.

[0067] Among them, the receiving groove 64 can be arranged on the surface of the base 6 close to the first cover plate 7, that is, the receiving groove 64 is arranged on the upper surface of the base 6, and the first cover plate 7 closes the opening (defined as the second opening) formed by the receiving groove 64 on the upper surface of the base 6, thereby realizing the closing of the receiving groove 64.

[0068] The first cover plate 7 closing the second opening can mean that: in the orthographic projection on a plane perpendicular to the first direction, the projection of the second opening is completely located within the projection of the lower surface of the first cover plate 7, and a part of the projection of the second opening coincides with the projection of the opening formed by the fourth through hole 72 on the lower surface of the first cover plate 7.

[0069] In one embodiment, the first through hole 61 is arranged on the bottom surface of the receiving hole 63, and the second through hole 62 is arranged on the bottom surface of the receiving groove 64. At the same time, both the first through hole 61 and the second through hole 62 penetrate through to the lower surface of the base 6.

[0070] As Figure 4 shown, in one embodiment, the receiving groove 64 is arranged around the receiving hole 63, and the receiving groove 64 is an open-loop structure. After assembly, in the circumferential direction of the receiving groove 64, the first through hole 61 and the third through hole 71 are respectively located at both ends of the receiving groove 64.

[0071] In addition, the receiving groove 64 and the receiving hole 63 can be coaxially arranged.

[0072] As Figure 4 shown, in one embodiment, the base 6 includes a bottom plate 65, a first annular protrusion 66, a second annular protrusion 67 and a first stopper 68. The first annular protrusion 66, the second annular protrusion 67 and the first stopper 68 are all arranged on the bottom plate 65, and all three are located on the surface of the bottom plate 65 close to the first cover plate 7.

[0073] Among them, the first annular protrusion 66 is located inside the second annular protrusion 67 and is spaced from it. The first stopper 68 is located between the first annular protrusion 66 and the second annular protrusion 67 and is respectively connected to the first annular protrusion 66 and the second annular protrusion 67. Among them, an annular groove is formed between the first annular protrusion 66 and the second annular protrusion 67, and the first stopper 68 partitions the annular groove to form an open-loop receiving groove 64.

[0074] The axes of the first annular protrusion 66 and the second annular protrusion 67 can be parallel, and preferably, they are coaxially arranged.

[0075] In addition, the bottom plate 65 is respectively connected to one end of the first annular protrusion 66 and one end of the second annular protrusion 67. The bottom plate 65 and the first annular protrusion 66 enclose to form a receiving hole 63; the bottom plate 65, the first annular protrusion 66, the second annular protrusion 67 and the first stopper 68 enclose to form a receiving groove 64. Among them, the receiving hole 63 can be the inner hole of the first annular protrusion 66, and the receiving groove 64 is located between the first annular protrusion 66 and the second annular protrusion 67.

[0076] In one embodiment, in the radial direction of the first annular protrusion 66, the bottom plate 65 protrudes from the first annular protrusion 66 to form a flange structure that circumferentially surrounds the second annular protrusion 67.

[0077] In one embodiment, both the first annular protrusion 66 and the second annular protrusion 67 are circular ring structures, and the bottom plate 65 is a cylindrical structure. Among them, the diameter of the bottom plate 65 is greater than the outer diameter of the second annular protrusion 67, and the inner diameter of the second annular protrusion 67 is greater than the outer diameter of the first annular protrusion 66.

In addition, the surface of the first annular protrusion 66 facing away from the bottom plate 65 and the surface of the second annular protrusion 67 facing away from the bottom plate 65 can both be flat surfaces and be flush. The lower surface of the base 6 is the surface of the bottom plate 65 facing away from the first annular protrusion 66.

[0079] During subsequent assembly, the part of the bottom plate 65 that protrudes from the second annular protrusion 67 (i.e., the flange structure) can be in contact with the main spring 1. And the first cover plate 7 is simultaneously in contact with the surface of the first annular protrusion 66 facing away from the bottom plate 65 and the surface of the second annular protrusion 67 facing away from the bottom plate 65. In addition, the leather cup 2 is actually pressed against the bottom plate 65.

[0080] In one embodiment, the first cover plate 7 can also be a cylindrical structure, and the diameters of the bottom plate 65 and the first cover plate 7 can be the same or different. After assembly, the two can be coaxially arranged.

[0081] The first through hole 61 is provided on the bottom surface of the receiving hole 63, which actually means that the first through hole 61 is provided on the bottom plate 65. The second through hole 62 is provided on the bottom surface of the receiving groove 64, which actually means that the second through hole 62 is provided on the bottom plate 65.

[0082] Such as Figure 4As shown, in one embodiment, a first limiting structure 69 is provided on the base 6, and a second limiting structure 73 is provided on the first cover plate 7. The first limiting structure 69 and the second limiting structure 73 cooperate to limit the relative positions of the base 6 and the first cover plate 7. Specifically, it limits the relative positions of the base 6 and the first cover plate 7 in the circumferential direction of the base 6.

[0083] Among them, the first limiting structure 69 can be a clamping groove, and the second limiting structure 73 can be a clamping block. In addition, the clamping groove can be provided on the upper surface of the base 6 (which can be provided on the second annular protrusion 67), and the clamping block can be provided on the lower surface of the first cover plate 7. In other embodiments, it can also be that the first limiting structure 69 is a clamping block and the second limiting structure 73 is a clamping groove.

[0084] As Figure 4 shown, in one embodiment, an installation groove 74 is provided on the first cover plate 7. When the second cover plate 8 approaches the first cover plate 7, the second cover plate 8 can close the installation groove 74, and both the fourth through hole 72 and the fifth through hole 81 communicate with the installation groove 74 to form the second flow channel. That is, the second flow channel is composed of the fourth through hole 72, the fifth through hole 81, and the installation groove 74.

[0085] Among them, the installation groove 74 can be provided on the surface of the first cover plate 7 close to the second cover plate 8, that is, the installation groove 74 is provided on the upper surface of the first cover plate 7. The second cover plate 8 can abut against the upper surface of the first cover plate 7 and close the opening (defined as the third opening) formed by the installation groove 74 on the upper surface of the first cover plate 7, thereby realizing the closure of the installation groove 74.

[0086] The second cover plate 8 closing the third opening can mean that: in the orthographic projection on a plane perpendicular to the first direction, the projection of the third opening is completely within the projection of the lower surface of the second cover plate 8, and a part of the projection of the third opening coincides with the projection of the opening formed by the fifth through hole 81 on the lower surface of the second cover plate 8.

[0091] Such as Figure 4 As shown, in an embodiment, the mounting groove 74 is provided around the mounting hole 75, and the mounting groove 74 is an open-loop structure. This can increase the length of the mounting groove 74 without changing the size of the second cover plate 8.

[0092] After assembly, in the circumferential direction of the mounting groove 74, the fourth through hole 72 and the fifth through hole 81 are respectively located at both ends of the mounting groove 74.

[0093] In addition, the receiving groove 64 and the receiving hole 63 can be coaxially arranged.

[0094] In an embodiment, the third through hole 71 is provided on the bottom surface of the mounting hole 75, and the fourth through hole 72 is provided on the bottom surface and / or the side surface of the mounting groove 74.

The third annular protrusion 77, the fourth annular protrusion 78, and the second stopper 79 are all provided on the support plate 76, and all three are located on the surface of the support plate 76 close to the second cover plate 8.

[0096] Among them, the third annular protrusion 77 is located inside the fourth annular protrusion 78, and the two are spaced apart. The second stopper 79 is located between the third annular protrusion 77 and the fourth annular protrusion 78, and is respectively connected to the third annular protrusion 77 and the fourth annular protrusion 78. Among them, an annular groove is formed between the third annular protrusion 77 and the fourth annular protrusion 78, and the second stopper 79 divides the annular groove to form an open-loop mounting groove 74.

[0098] In addition, the support plate 76 is respectively connected to one end of the third annular protrusion 77 and one end of the fourth annular protrusion 78. The support plate 76 and the third annular protrusion 77 enclose to form a mounting hole 75; the support plate 76, the third annular protrusion 77, the fourth annular protrusion 78 and the second stop block 79 enclose to form a mounting groove 74. Among them, the mounting hole 75 can be the inner hole of the third annular protrusion 77, and the mounting groove 74 is located between the third annular protrusion 77 and the fourth annular protrusion 78.

[0099] In one embodiment, in the radial direction of the third annular protrusion 77, the support plate 76 protrudes from the third annular protrusion 77 to form a flange structure that circumferentially surrounds the fourth annular protrusion 78.

[0100] In one embodiment, both the third annular protrusion 77 and the fourth annular protrusion 78 are circular ring structures, and the support plate 76 is a cylindrical structure. Among them, the diameter of the support plate 76 is greater than the outer diameter of the fourth annular protrusion 78, and the inner diameter of the fourth annular protrusion 78 is greater than the outer diameter of the third annular protrusion 77. The support plate 76 and the fourth annular protrusion 78 can be coaxially arranged.

[0101] In this embodiment, the upper surface of the first cover plate 7 includes the surface of the third annular protrusion 77 facing away from the support plate 76 and the surface of the fourth annular protrusion 78 facing away from the support plate 76. In addition, both the surface of the third annular protrusion 77 facing away from the support plate 76 and the surface of the fourth annular protrusion 78 facing away from the support plate 76 can be flat surfaces and are flush. The lower surface of the first cover plate 7 is the surface of the support plate 76 facing away from the third annular protrusion 77.

[0102] During subsequent assembly, the part of the support plate 76 protruding from the fourth annular protrusion 78 (i.e., the flange structure) can be in contact with the main spring 1. And the second cover plate 8 is simultaneously in contact with the surface of the third annular protrusion 77 facing away from the support plate 76 and the surface of the fourth annular protrusion 78 facing away from the support plate 76.

[0103] In one embodiment, the second cover plate 8 can also be a cylindrical structure. The diameter of the second cover plate 8 is smaller than the diameter of the support plate 76, and the outer diameters of the support plate 76 and the fourth annular protrusion 78 can be the same or different. After assembly, the second cover plate 8 and the support plate 76 can be coaxially arranged.

[0104] In addition, the diameter of the support plate 76 is smaller than the diameter of the bottom plate 65, and the diameter of the support plate 76 and the outer diameter of the second annular protrusion 67 can be the same or different.

[0105] The third through hole 71 is provided on the bottom surface of the mounting hole 75, which actually means that the third through hole 71 is provided on the support plate 76. When the fourth through hole 72 is provided on the bottom surface of the mounting groove 74, it is actually provided on the support plate 76. When the fourth through hole 72 is provided on the side surface of the mounting groove 74, it is actually provided on the surface of the fourth annular protrusion 78 close to the third annular protrusion 77 and penetrates the support plate 76 in the first direction.

[0106] As Figure 2 and Figure 5 shown, in an embodiment, the decoupling assembly 20 further includes a connecting rod 92; a first avoidance hole is provided on the base 6, a second avoidance hole is provided on the decoupling film 91, and a third avoidance hole is provided on the first cover plate 7. The first avoidance hole, the second avoidance hole, and the third avoidance hole are opposite to form an avoidance channel; the connecting rod 92 is connected to the second cover plate 8, and the connecting rod 92 passes through the second cover plate 8, the decoupling film 91, and the base 6 from the avoidance channel; along the arrangement direction of the base 6 and the first cover plate 7, the connecting rod 92 can move in the avoidance channel to drive the second cover plate 8 to approach or move away from the first cover plate 7. That is, during operation, the connecting plate can be driven to move in the first direction, thereby driving the second cover plate 8 to approach or move away from the first cover plate 7. Moreover, the connecting rod 92 passes through from the avoidance channel, which can effectively utilize the space and is beneficial to reducing the size of the suspension 100.

[0107] Among them, "the first avoidance hole, the second avoidance hole, and the third avoidance hole are opposite" means that in the orthographic projection on a plane perpendicular to the first direction, the projections of the first avoidance hole, the second avoidance hole, and the third avoidance hole have an overlapping area.

[0108] As Figure 5 shown, in an embodiment, a resisting structure 921 is provided on the connecting rod 92. When the connecting rod 92 moves along the direction from the base 6 to the first cover plate 7, the resisting structure 921 can abut against the base 6 to prevent the connecting rod 92 from exiting the avoidance space. In this embodiment, the connecting rod 92 includes a rod body 922 and a resisting structure 921. The rod body 922 passes through the avoidance channel, and the rod body 922 is connected to the second cover plate 8.

[0109] The rod body 922 and the resisting structure 921 can be an integral structure. For example, the two can be formed into an integral body by welding; or, the rod body 922 and the resisting structure 921 can be detachably connected. For example, the position can be detachably connected by means of a threaded connection. In addition, the resisting structure 921 is an annular structure, which is arranged around the rod body 922, and the resisting structure 921 can be coaxially arranged with the rod body 922. In addition, the rod body 922 and the second cover plate 8 can be coaxially arranged.

[0110] In one embodiment, the second cover plate 8 is detachably connected to the connecting rod 92. In this way, when one of them is damaged, only the damaged one needs to be replaced, thereby reducing the maintenance cost. Additionally, the detachable connection between the second cover plate 8 and the connecting rod 92 can be achieved by means of a threaded connection. Specifically, the second cover plate 8 is provided with a threaded hole, and the rod body 922 is provided with an external thread.

[0111] In one embodiment, along the arrangement direction of the base 6 and the first cover plate 7, the avoidance channel can guide the movement of the connecting rod 92 so that the connecting rod 92 moves more stably.

[0112] As Figure 2 shown, in one embodiment, the connecting rod 92 is connected to the leather cup 2 to realize the connection between the second cover plate 8 and the leather cup 2. When the leather cup 2 moves in the first direction, it can drive the connecting rod 92 to move in the first direction, and then drive the second cover plate 8 to move in the first direction.

[0113] Alternatively, the resisting structure 921 can be connected to the leather cup 2, thereby realizing the connection between the connecting rod 92 and the leather cup 2. In addition, the connection between the connecting rod 92 and the leather cup 2 can be a vulcanized connection.

[0114] In one embodiment, a sealing layer is provided on at least one of the surface of the first cover plate 7 close to the second cover plate 8 (i.e., the upper surface of the first cover plate 7) and the surface of the second cover plate 8 close to the first cover plate 7 (i.e., the lower surface of the second cover plate 8) so that the second cover plate 8 and the first cover plate 7 can be in sealed contact. When the first cover plate 7 abuts against the second cover plate 8, the two can be sealed through the sealing layer. Additionally, the sealing layer can be a rubber layer.

[0115] The embodiment of the present utility model further provides a vehicle, which includes the mount 100 described in any one of the above embodiments.

[0116] In addition, the vehicle further includes a subframe and a powertrain. Among them, the mount 100 can be respectively connected to the subframe and the powertrain.
