Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a suspension buffer pump, a seat, and a vehicle. Background Technology

[0002] To improve seat comfort, airbags are usually installed on the seats and inflated using a corresponding suspension cushioning pump.

[0003] Existing suspended damping pumps typically include a housing, an air pump, a connector, and a vibration damping pad. The housing has a receiving cavity, and the air pump is housed within the receiving hole to reduce noise. The air pump is suspended in the receiving cavity via the connector, which applies axial force along the mounting hole to keep the air pump in the appropriate position. The vibration damping pad has a mounting hole and fits over the air pump to isolate it from the housing, preventing the side of the air pump from contacting the housing.

[0004] However, existing suspension buffer pumps are cumbersome to assemble and have low production efficiency. Utility Model Content

[0005] This utility model provides a suspension buffer pump, a seat, and a vehicle, aiming to solve the problems of cumbersome assembly and low production efficiency of pneumatic devices in the prior art.

[0006] This utility model provides a suspended buffer pump, including a housing, an air pump, and a vibration damping pad. The housing has a receiving cavity and a supporting structure. The supporting structure, the air pump, and the vibration damping pad are all located within the receiving cavity. The vibration damping pad includes a carrier, an elastic element, and a mounting element connected in sequence. The carrier has a mounting through hole, through which the air pump passes. In the radial direction of the mounting through hole, the elastic element can elastically deform to allow the vibration damping pad to elastically isolate the housing and the air pump. In the axial direction of the mounting through hole, the carrier carries the air pump, and the supporting structure carries the mounting element.

[0007] Optionally, the housing includes a first housing and a second housing; in the axial direction of the mounting through hole, the first housing is connected to one end of the second housing to enclose and form the receiving cavity; the support structure is disposed on the first housing, and the second housing abuts against one end of the mounting member opposite to the support structure.

[0008] Optionally, the first housing is provided with a first receiving hole, at least a portion of which is used to form at least a portion of the receiving cavity; the support structure is located within the first receiving hole; the second housing extends into the first receiving hole and abuts against the end of the mounting member opposite to the support structure.

[0009] Optionally, in the direction from the second housing to the first housing, the first receiving hole includes a first hole and a second hole connected in sequence; the diameter of the first hole is larger than the diameter of the second hole to form a stepped surface between the first hole and the second hole; the support structure is at least a portion of the stepped surface.

[0010] Optionally, the housing is further provided with a limiting structure, which is located within the receiving cavity; in the radial direction of the mounting through hole, the limiting structure is located between the mounting member and the carrier member.

[0011] Optionally, the limiting structure surrounds the carrier; the limiting structure has an avoidance notch, and the elastic member passes through the limiting structure from the avoidance notch.

[0012] Optionally, the support structure is an annular platform formed on the inner wall of the outer shell, and the limiting structure is an annular limiting wall that is higher than the support structure in the axial direction of the mounting through hole. The limiting structure, the support structure, and the outer shell form a support groove, and the mounting component is installed in the support groove.

[0013] Optionally, the mounting component is a ring structure and is sleeved outside the bearing component, with one axial end of the mounting component abutting against the support structure; multiple elastic elements are provided and arranged sequentially around the bearing component; the bearing component is provided with at least one protruding structure, which is located between the bearing component and the mounting component; the protruding structure supports the air pump in the axial direction of the mounting through hole.

[0014] This utility model embodiment also provides a seat, including a seat body, an air storage device, and a suspension buffer pump as described in any one of the above; the air storage device is connected to the seat body; the suspension buffer pump is connected to the air storage device and is used to inflate the air storage device to deform the air storage device.

[0015] This utility model embodiment also provides a vehicle, including the seat described above.

[0016] In the suspension buffer pump, seat, and vehicle provided in this embodiment of the utility model, the housing can provide support for the air pump along the axial direction of the mounting hole through a vibration damping pad, so that the air pump can be held in the corresponding position within the receiving cavity. Compared with the prior art, the arrangement of this embodiment eliminates the need for a connector to apply force to the air pump along the axial direction of the mounting hole, thereby eliminating the need for a connector. This reduces the number of components in the suspension buffer pump, facilitating its assembly and improving its production efficiency.

[0017] In addition, by placing both the support structure and the vibration damping pad inside the housing, the outer shell can be used to shield and protect them, thereby preventing the vibration damping pad from being scratched by external objects, improving its service life and the support effect on the air pump.

[0021] To make the technical problems solved, technical solutions, and beneficial effects of this 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1 to 3 As shown, in one embodiment, the suspended buffer pump 10 includes a housing 1, an air pump 2, and a vibration damping pad 3; the housing 1 has a receiving cavity 11 and a support structure 12; the support structure 12, the air pump 2, and the vibration damping pad 3 are all located within the receiving cavity 11; the vibration damping pad 3 includes a bearing member 31, an elastic member 32, and a mounting member 33 connected in sequence; the bearing member 31 is provided with a mounting through hole 34, through which the air pump 2 passes; in the radial direction of the mounting through hole 34, the elastic member 32 can elastically deform to allow the vibration damping pad 3 to elastically isolate the housing 1 and the air pump 2; in the axial direction of the mounting through hole 34, the bearing member 31 supports the air pump 2, and the support structure 12 supports the mounting member 33.

[0025] In this embodiment, along the axial direction of the mounting through hole 34, the outer casing 1 can provide support for the air pump 2 through the vibration damping pad 3, so that the air pump 2 can be held in the corresponding position within the receiving cavity 11. Compared with the prior art, the arrangement of this embodiment eliminates the need for the connecting member to provide axial force to the air pump 2 along the mounting hole, thereby eliminating the need for the connecting member. This reduces the number of parts in the suspended buffer pump 10, facilitating the assembly of the suspended buffer pump 10 and improving its production efficiency.

[0026] In addition, by placing both the support structure 12 and the vibration damping pad 3 inside the receiving cavity 11, the outer shell 1 can be used to shield and protect them, thereby preventing the vibration damping pad 3 from being scratched by external objects, improving its service life and the support effect on the air pump 2.

[0027] "Vibration damping pad 3 elastically isolates housing 1 and air pump 2" means that housing 1 and air pump 2 are separated by vibration damping pad 3 in the radial direction of mounting through hole 34. At the same time, since vibration damping pad 3 can elastically deform in this direction, air pump 2 can sway relative to housing 1 in this direction.

[0028] "The support member 31 is provided with a mounting through hole 34" means that the support member 31 is provided with a hole that extends through the support member 31. This hole is referred to as "mounting through hole 34" in this document. Moreover, the extension direction of the hole can be the extension direction of its axis, that is, its axial direction.

[0029] In one embodiment, the axial direction of the mounting through hole 34 is a straight line, and the axial direction of the mounting through hole 34 is perpendicular to its radial direction. Figure 2 and Figure 3 In the example shown, the axial direction of the mounting through hole 34 is parallel to the Z-axis, and the axial direction of the mounting through hole 34 can be parallel to the vertical direction. In this case, the radial direction of the mounting through hole 34 is parallel to the horizontal direction.

[0030] In addition, the mounting through hole 34 can be a round hole, a square hole, or a hole of other shapes.

[0031] like Figure 3 As shown, in one embodiment, the mounting member 33 is a ring structure and is sleeved on the outside of the bearing member 31, with one axial end of the mounting member 33 abutting against the support structure 12. Multiple elastic members 32 are provided and arranged sequentially around the bearing member 31. This improves the limiting and isolation effect between the air pump 2 and the outer casing 1. "Multiple" means two or more, and the meaning of the term "multiple" is the same in all embodiments.

[0032] "Abutting" can refer to two objects directly touching each other, or it can refer to two objects indirectly touching each other through an intermediary.

[0033] Furthermore, the bearing member 31 is essentially the inner ring structure of the vibration damping pad 3, and the mounting member 33 is the outer ring structure of the vibration damping pad 3. The bearing member 31 and the mounting member 33 are spaced apart. Additionally, the axial direction of the bearing member 31 is not perpendicular to the axial direction of the mounting member 33; for example, their axial directions can be parallel to each other.

[0034] In one embodiment, the carrier 31 and the mounting member 33 may be coaxially arranged.

[0035] In addition, each elastic element 32 can be evenly arranged around the bearing element 31.

[0036] In one embodiment, the support member 31 can be a rubber ring, which can also undergo a certain elastic deformation in the radial direction of the mounting through hole 34. This facilitates the assembly of the support member 31 and the air pump 2, and can improve the elastic deformation effect of the vibration damping pad 3 in the radial direction of the mounting through hole 34.

[0037] Alternatively, the mounting component 33 can also be a rubber ring, which can also undergo a certain elastic deformation in the radial direction of the mounting through hole 34, thereby improving the elastic deformation effect of the damping pad 3 in the radial direction of the mounting through hole 34.

[0038] Alternatively, the elastic element 32 can also be a rubber part or other object that can produce elastic deformation in the radial direction of the mounting through hole 34.

[0039] In one embodiment, the support member 31, the elastic member 32, and the mounting member 33 may be an integrally formed structure.

[0040] In one embodiment, the elastic element 32 can be a hollow structure, which can improve its elastic deformation effect in the radial direction of the mounting through hole 34. Of course, the elastic element 32 can also be a solid structure to facilitate the production and manufacturing of the elastic element 32.

[0041] like Figure 3 As shown, in one embodiment, the support member 31 is provided with at least one protrusion structure 35, which is located between the support member 31 and the mounting member 33; the protrusion structure 35 supports the air pump 2 in the axial direction of the mounting through hole 34. This can improve the support effect on the air pump 2.

[0042] In the axial direction of the mounting through hole 34, the two ends of the protruding structure 35 can be flush with the two ends of the bearing member 31.

[0043] In addition, the protruding structure 35 and the mounting part 33 are spaced apart, and after assembly, the protruding structure 35 and the limiting structure 13 are spaced apart.

[0044] like Figure 2 and Figure 4 As shown, in one embodiment, the air pump 2 includes a pump body 21 and a power source 22. The power source 22 is connected to the pump body 21 and is used to drive the pump body 21. The power source 22 can be a device such as an electric motor that can drive the pump body 21 to work. When the pump body 21 is working, it can fill the target object (such as the air storage device described below) with air.

[0045] In one embodiment, the carrier 31 may abut against the pump body 21 to support the air pump 2.

[0046] like Figure 4As shown, in one embodiment, in the axial direction of the mounting through hole 34, the pump body 21 includes a first part 211 and a second part 212 connected in sequence; in the radial direction of the mounting through hole 34, the second part 212 protrudes from the first part 211 toward the outer casing 1; the power source 22 is disposed on the side of the first part 211 away from the second part 212; the support member 31 is sleeved on the first part 211 and abuts against the second part 212 in the axial direction of the mounting through hole 34.

[0047] The phrase "in the radial direction of the mounting through hole 34, the second part 212 protrudes toward the outer shell 1 from the first part 211" can mean that in the circumferential direction of the mounting through hole 34, the second part protrudes toward the outer shell 1 from the first part 211 all the way, or that only a part of the second part 212 protrudes toward the outer shell 1 from the first part 211.

[0048] In the radial direction of the mounting through hole 34, the portion of the second part 212 that protrudes from the first part 211 toward the outer casing 1 is defined as the protrusion. After assembly, the support member 31 abuts against the protrusion, thereby supporting the air pump 2. In addition, the protruding structure 35 also abuts against the protrusion of the second part 212, thereby supporting the air pump 2.

[0049] In a scenario where the axis of the mounting hole 34 is parallel to the vertical direction, the second part 212 can be located above the first part 211, and in this case, the power source 22 is located below the first part 211.

[0050] In addition, both the pump body 21 and the power source 22 can be existing designs.

[0051] like Figure 2 As shown, in one embodiment, in the axial direction of the mounting through hole 34, the carrier 31 includes a first carrier portion 311 and a second carrier portion 312 connected in sequence; wherein, the first carrier portion 311 is sleeved on the pump body 21 and is interference-fitted with the pump body 21; the second carrier portion 312 is sleeved on the power source 22 and is spaced apart from the power source 22.

[0052] This configuration avoids direct contact between the power source 22 and the bearing 31, thereby reducing the transmission of vibration from the power source 22 to the bearing 31, reducing the transmission of vibration from the power source 22 to the outer casing 1, improving the vibration damping effect of the damping pad 3, and further reducing the noise of the suspension buffer pump 10.

[0053] Moreover, when the power source 22 and the pump body 21 come into contact with the bearing 31 at the same time, the vibration of the two acts on the bearing 31 at the same time, which may cause resonance. By isolating the bearing 31 from the power source 22, the resonance can be avoided, the vibration damping effect of the damping pad 3 can be improved, and the noise of the suspension buffer pump 10 can be further reduced.

[0054] Meanwhile, setting the pump body 21 and the carrier 31 to an interference fit can also improve the limiting and isolation effect of the air pump 2 in the radial direction of the mounting through hole 34, and make it easier to prevent the air pump 2 from contacting the outer shell 1 in the radial direction of the mounting through hole 34.

[0055] It should be understood that both the first support portion 311 and the second support portion 312 have a portion of the mounting through hole 34. The portion of the mounting through hole 34 on the first support portion 311 is the first section hole, and the portion of the mounting through hole 34 on the second support portion 312 is the second section hole. The pump body 21 is installed through the first section hole, and the power source 22 is installed through the second section hole.

[0056] In addition, the aforementioned support member 31 is fitted onto the first part 211, which actually means that the first support part 311 is fitted onto the first part 211.

[0057] like Figure 5 and Figure 6 As shown, in one embodiment, the outer shell 1 is further provided with a limiting structure 13, which is located within the receiving cavity 11. In the radial direction of the mounting through hole 34, the limiting structure 13 is located between the mounting member 33 and the carrier member 31, and can abut against the surface of the mounting member 33 near the carrier member 31, wherein the surface of the mounting member 33 near the carrier member 31 is the inner side surface of the mounting member 33. This prevents the vibration damping pad 3 from moving too far inward (i.e., along the direction from the mounting member 33 to the carrier member 31), ensuring the bearing effect of the outer shell 1 on the mounting member 33.

[0058] After assembly, the limiting structure 13 and the mounting part 33 can be spaced apart, and in this case, they do not abut against each other. Subsequently, if the vibration damping pad 3 shifts radially in the mounting through hole 34, the limiting structure 13 can abut against the mounting part 33 to limit its shift size.

[0059] In addition, it should be understood that when the damping pad 3 moves outward (i.e. along the direction from the support member 31 to the mounting member 33), the outer shell 1 can limit its maximum movement distance. That is, at this time, the outer shell 1 can abut against the surface of the mounting member 33 away from the support member 31, wherein the surface of the mounting member 33 away from the support member 31 is the outer side surface of the mounting member 33.

[0060] like Figure 5 and Figure 6 As shown, in one embodiment, the limiting structure 13 surrounds the support member 31, and in this case, the limiting structure 13 is an annular limiting wall. The limiting structure 13 has a clearance notch 131, through which the elastic member 32 passes. This improves the limiting effect of the limiting structure 13 on the mounting member 33. Furthermore, in this case, the mounting member 33 also surrounds the outside of the limiting structure 13.

[0061] It should be understood that the clearance notch 131 passes radially through the mounting through hole 34 through the limiting structure 13, so that the elastic element 32 can pass through the limiting structure 13 at the clearance notch 131.

[0062] Alternatively, the clearance notch 131 can also be a through-hole 13 along the axial direction of the mounting hole 34 to facilitate assembly.

[0063] In one embodiment, after assembly, the limiting structure 13 and the carrier 31 are spaced apart.

[0064] In one embodiment, the support structure 12 is a ring structure, which may be an annular platform formed on the inner wall of the outer shell 1. It surrounds the load-bearing member 31. This arrangement improves the support and load-bearing effect on the mounting member 33.

[0065] Furthermore, the support structure 12 can directly contact the mounting member 33, and the area of ​​the support structure 12 that contacts the mounting member 33 is an annular area, which surrounds the support member 31. That is, the support structure 12 can contact the entire circumference of the mounting member 33.

[0066] Furthermore, when the support structure 12 is an annular platform formed on the inner wall of the outer shell 1, and the limiting structure 13 is an annular limiting wall, the limiting structure 13 is higher than the support structure 12 in the axial direction of the mounting through hole 34. That is, the limiting structure 13 protrudes from the support structure 12 along the direction from the power source 22 to the pump body 21. At this time, the limiting structure 13, the support structure 12, and the outer shell 1 form a support groove, and the mounting part 33 is installed in the support groove, which can improve the limiting effect on the mounting part 33.

[0067] like Figure 2 and Figure 5 As shown, in one embodiment, the outer casing 1 includes a first housing 14 and a second housing 15; in the axial direction of the mounting through hole 34, the first housing 14 is connected to one end of the second housing 15 to form a receiving cavity 11; a support structure 12 is disposed on the first housing 14, and the second housing 15 abuts against the end of the mounting member 33 opposite to the support structure 12. This allows for axial positioning of both ends of the mounting member 33 in the mounting through hole 34, thereby making the vibration damping pad 3 more firmly and stably installed.

[0068] The first housing 14 may be located below the second housing 15.

[0069] like Figure 2 and Figure 5As shown, in one embodiment, the first housing 14 is provided with a first receiving hole 141, at least a portion of which is used to form at least a portion of the receiving cavity 11. A support structure 12 is disposed within the first receiving hole 141. After assembly, the second housing 15 extends into the first receiving hole 141 and abuts against the end of the mounting member 33 opposite to the support structure 12. This facilitates the assembly of the first housing 14 and the second housing 15.

[0070] In the axial direction of the mounting through hole 34, a first receiving hole 141 is provided on the surface of the first housing 14 near the second housing 15. Moreover, the first receiving hole 141 can be a blind hole.

[0071] Furthermore, the support structure 12 and the end face of the first housing 14 with the first receiving hole 141 (i.e., the upper end face of the first housing 14) are spaced apart. After assembly, the mounting member 33 extends into the first receiving hole 141, and its lower end can abut against the support structure 12.

[0072] like Figure 5 As shown, in one embodiment, in the direction from the second housing 15 to the first housing 14, the first receiving hole 141 includes a first hole 142 and a second hole 143 connected in sequence; the diameter of the first hole 142 is larger than the diameter of the second hole 143, so as to form a stepped surface between the first hole 142 and the second hole 143; the support structure 12 is at least a portion of the stepped surface. That is, the first receiving hole 141 is set as a stepped hole, and at least a portion of the stepped surface of the stepped hole is set as the support structure 12, which facilitates the formation of the support structure 12, thereby facilitating the production and manufacturing of the outer shell 1.

[0073] Either the first hole 142 or the second hole 143 can be a round hole, a square hole, or a hole of other shapes. When the first hole 142 or the second hole 143 is not a round hole, its diameter can refer to its equivalent diameter.

[0074] like Figure 2 and Figure 7 As shown, in one embodiment, the second housing 15 is provided with a second receiving hole 151, at least a portion of the second receiving hole 151 is used to form at least a portion of the receiving cavity 11.

[0075] In the axial direction of the mounting through hole 34, a second receiving hole 151 is provided on the surface of the second housing 15 near the first housing 14. Moreover, the second receiving hole 151 can be a blind hole.

[0076] After assembly, the second receiving hole 151 and the first receiving hole 141 are connected. A part of the air pump 2 is located in the first receiving hole 141, and another part of the air pump 2 is located in the second receiving hole 151.

[0077] like Figure 7As shown, in one embodiment, the second housing 15 is provided with a stop structure 152, which is used to limit the depth of the second housing 15 extending into the first receiving hole 141. Specifically, the stop structure 152 is located on the outer surface of the second housing 15, and when the second housing 15 extends to the maximum position of the first receiving hole 141, the stop structure 152 can abut against the first housing 14.

[0078] The blocking structure 152 is an annular protrusion that surrounds the second housing 15.

[0079] In one embodiment, the first housing 14 and the second housing 15 are snapped together. One of the first housing 14 and the second housing 15 is provided with a snap hole 16, and the other is provided with a snap block 17. After assembly, the snap block 17 is inserted into the snap hole 16 to achieve the snap-fit ​​between the first housing 14 and the second housing 15.

[0080] Among them, Figure 5 and Figure 7 In the example shown, the locking hole 16 is provided in the first housing 14, the locking block 17 is provided in the second housing 15, and the locking hole 16 is located on the hole wall of the first hole 142 and penetrates the first housing 14 radially along the mounting through hole 34.

[0081] In addition, there are multiple slots 16 and slot blocks 17, and there can be a one-to-one correspondence between them. After assembly, the slot block 17 is inserted into the corresponding slot 16.

[0082] In addition, multiple slots 16 can be evenly arranged around the first receiving hole 141.

[0083] like Figure 7 As shown, in one embodiment, the second housing 15 is provided with a plurality of grooves 153, wherein the grooves 153 penetrate the second housing 15 in the radial direction of the mounting through hole 34; the grooves 153 extend to the surface of the second housing 15 near the first housing 14 in the axial direction of the mounting through hole 34; and the grooves 153 are arranged sequentially around the second receiving hole 151 in the circumferential direction of the mounting through hole 34. A spring piece is formed between two adjacent grooves 153, and a locking block 17 is provided on the spring piece, so that the area where the locking block 17 is located can be deformed to facilitate its insertion into the locking hole 16.

[0084] In addition, the spring clips and the locking blocks 17 are in one-to-one correspondence, with the locking blocks 17 set on the spring clips corresponding to them.

[0085] In one embodiment, the limiting structure 13 is disposed on the first housing 14 and located in the first receiving hole 141. Moreover, the limiting structure 13 may be disposed on the stepped surface and spaced apart from the hole wall of the first hole 142. In this case, the limiting structure 13, the supporting structure 12 and the hole wall of the first hole 142 constitute the supporting groove.

[0086] like Figure 2 and Figure 7 As shown, in one embodiment, the outer casing 1 is further provided with a connection hole 18 to allow the air pump 2 to connect to the target object. The connection hole 18 extends from the outer surface of the outer casing 1 to the connecting cavity 11.

[0087] exist Figure 2 In the example shown, the air pump 2 is connected to the target object via an air pipe 4, which passes through the connection hole 18. One end of the air pipe 4 extends into the receiving cavity 11 and connects to the air outlet of the pump body 21; the other end of the air pipe 4 extends into the outer casing 1 to connect to the target object. In this example, the air pipe 4 can also be part of the structure of the suspended buffer pump 10, which facilitates the subsequent use of the suspended buffer pump 10.

[0088] In another embodiment, the connection hole 18 may be provided in the second housing 15, extending from the outer surface of the second housing 15 to the communication second receiving hole 151.

[0089] like Figure 5 As shown, in one embodiment, the outer casing 1 is further provided with a vent 19, which extends from the outer surface of the outer casing 1 to the connecting cavity 11. Gas outside the outer casing 1 can enter the cavity 11 through the vent 19, then enter the air inlet of the air pump 2, and finally exit from the air outlet of the air pump 2 into the target object.

[0090] In one embodiment, a vent 19 is provided in the first housing 14, extending from the outer surface of the first housing 14 to the first receiving hole 141.

[0091] Alternatively, the vent 19 may extend to the surface of the first housing 14 near the second housing 15, which would facilitate the second housing 15 extending into the first housing 14.

[0092] like Figure 6 As shown, in one embodiment, the inner wall of the receiving cavity 11 is provided with a plurality of noise-reducing protrusions 111, which extend axially along the mounting through hole 34; the plurality of noise-reducing protrusions 111 are arranged sequentially around the air pump 2. The noise-reducing protrusions 111 can reflect and weaken the sound generated by the air pump 2 when it is working, thereby reducing the noise of the entire suspended buffer pump 10.

[0093] In addition, the "inner wall of the receiving cavity 11" is the inner wall of the outer shell 1. The inner wall of the outer shell 1 encloses and forms the receiving cavity 11. The inner wall of the outer shell 1 includes at least a portion of the inner wall of the first shell 14 and at least a portion of the inner wall of the second shell 15. The inner wall of the first shell 14 encloses and forms the first receiving hole 141, and the inner wall of the second shell 15 encloses and forms the second receiving hole 151.

[0094] In the actual product, both the first housing 14 and the second housing 15 are provided with multiple noise-absorbing protrusions 111.

[0095] In addition, in the circumferential direction of the mounting through hole 34, there can be a certain distance between two adjacent sound-absorbing structures.

[0096] For a noise-absorbing protrusion 111, its width gradually increases along the direction from the protrusion 111 to the outer casing 1. The width direction of the protrusion 111 is perpendicular to its extension direction and perpendicular to its arrangement direction with the outer casing 1. This improves the sound reflection effect, thereby reducing noise. The noise-absorbing protrusion 111 can be a triangular structure.

[0097] like Figure 2 As shown, in one embodiment, the suspended buffer pump 10 further includes a first buffer pad 5; the first buffer pad 5 is elastically deformable in the axial direction of the mounting through hole 34, and is disposed between the end of the pump body 21 away from the power source 22 and the outer casing 1. When the pump body 21 sways along the direction from the power source 22 to the pump body 21, the first buffer pad 5 can buffer the movement to reduce vibration.

[0098] The first buffer pad 5 may be connected to the pump body 21 and spaced apart from the outer shell 1, or the first buffer pad 5 may be connected to the outer shell 1 and spaced apart from the pump body 21, or the first buffer pad 5 may be spaced apart from the pump body 21 and the outer shell 1, or the first buffer pad 5 may be connected to the pump body 21 and the outer shell 1.

[0099] In addition, the first buffer pad 5 can be a sponge pad or a rubber pad, etc.

[0100] like Figure 2 As shown, in one embodiment, the suspended buffer pump 10 further includes a second buffer pad 6; the second buffer pad 6 is elastically deformable in the axial direction of the mounting through hole 34, and is disposed between the end of the power source 22 away from the pump body 21 and the outer casing 1. When the pump body 21 sways along the direction from the pump body 21 to the power source 22, the movement can be buffered by the second buffer pad 6 to reduce vibration.

[0101] The second buffer pad 6 can be connected to the power source 22 and spaced apart from the housing 1, or the second buffer pad 6 can be connected to the housing 1 and spaced apart from the power source 22, or the second buffer pad 6 can be spaced apart from the power source 22 and the housing 1, or the second buffer pad 6 can be connected to the power source 22 and the housing 1.

[0102] In addition, the second buffer pad 6 can be a sponge pad or a rubber pad, etc.

[0103] In one embodiment, the second buffer pad 6 may be adhered to the power source 22.

[0105] Once the air reservoir is inflated, it can be used to support and / or massage occupants sitting on the seat.

[0106] Alternatively, the gas storage device can be a gas bag, etc.

[0108] It should be understood that the above-mentioned settings can also be replaced in other ways, such as: In other embodiments, any one of the carrier 31, elastic member 32 and mounting member 33 may be made of metal or plastic, etc.

[0109] In other embodiments, the limiting structure 13 may also be disposed on the second housing 15; or, a part of the limiting structure 13 may be disposed on the first housing 14, and the other part of the limiting structure 13 may be disposed on the second housing 15.

[0110] In other embodiments, the support structure 12 may also be located outside the receiving cavity 11, for example, the support structure 12 may be a boss provided on the outer surface of the outer shell 1.

[0111] In other embodiments, the target object may extend into the receiving cavity 11 through the connection hole 18 to connect with the air pump 2. Alternatively, the air pump 2 may extend out of the outer casing 1 through the connection hole 18 to connect with the target object.
