[0002] With the continuous development of the automotive industry, the comfort and quietness of vehicles are increasingly attracting the attention of consumers. Vehicle air pumps, as an important component in automobiles, generate a lot of vibration and noise during operation, which not only affects the riding experience of passengers inside the vehicle, but also may cause damage to other parts of the vehicle.

[0003] Currently, existing vehicle air pumps on the market are usually packaged with a shell made of metal or hard plastic. However, these traditional shells have limited effect in shock absorption and noise reduction, and cannot effectively absorb the vibration generated during air pump operation, resulting in vibration being transmitted to other parts of the vehicle body, causing resonance and noise of the vehicle.

[0010] According to the technical scheme provided by the embodiment of the present application, the soft shell is of an integral structure or a split structure.

[0011] According to the technical scheme provided in the embodiment of the present application, the first protruding structure comprises at least one buffer layer arranged radially along the soft shell, the buffer layer has a through hole in the center for penetrating the air source assembly, and the buffer layer is sleeved outside the air source assembly and abuts against the outer wall of the air source assembly.

[0012] According to the technical scheme provided in the embodiment of the present application, the soft shell is provided with a second through hole in communication with the accommodating cavity (4) for air inlet and / or allowing the wire harness to pass through the soft shell.

[0013] According to the technical scheme provided in the embodiment of the present application, the first protruding structure further comprises a plurality of protruding columns, the protruding columns comprise first protruding columns and second protruding columns, and the protruding height of the second protruding columns is smaller than the protruding height of the first protruding columns.

[0014] According to the technical scheme provided in the embodiment of the present application, when the soft shell is a split structure, a sealing element is arranged at the split connection.

The plurality of first protruding structures arranged on the inner wall further enhance the shock-absorbing effect. When the air pump works, the protruding structure abuts against the outer wall of the air source assembly, and through the deformation and buffering effect, the vibration energy is converted into other forms of energy, thereby greatly reducing the possibility of vibration transmission to the vehicle body and significantly reducing the generation of noise.

[0030] The present application will be further described in detail below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and are not a limitation on the application. In addition, it should be noted that, in order to facilitate the description, only the parts related to the application are shown in the drawings.

[0031] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in the case of no conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] Embodiment 1

[0033] As mentioned in the background, in order to solve the problems in the prior art, the present application proposes a damping and noise reduction shell of a vehicle seat air source device, as shown in Figure 1 , which comprises:

[0034] A soft shell 1, which has a containing cavity 4 inside, used to contain an air source assembly; the outer wall of the soft shell 1 has a fixing part, which is used to fix the soft shell 1 in a vehicle seat;

[0035] Further, the soft shell 1 is provided with a second through hole 16 communicating with the containing cavity 4, which is used for air inlet and / or wire harness passing through the soft shell 1. Specifically, the soft shell 1 is also provided with an air outlet 17.

[0036] Specifically, the soft shell 1 can be made of soft materials such as rubber and silicone which have elasticity. Its shape can be designed according to the shape of the air source assembly, for example, if the air source assembly is a cuboid, the soft shell 1 can also be designed as a cuboid to ensure adaptive assembly. The size of the containing cavity 4 should be able to contain the air source assembly, and after installing the air source assembly, there should be a certain gap between the inner wall of the soft shell 1 and the outer wall of the air source assembly, so that the soft shell 1 has enough deformation space when it is subjected to vibration.

[0037] A plurality of first protruding structures, which are provided on the inner wall of the soft shell 1, when the containing cavity 4 contains the air source assembly, the end of the first protruding structure away from the soft shell 1 is in contact with the outer wall of the air source assembly.

[0038] Further, the air source assembly comprises a gas pump body 22, and the outer wall of the air source assembly is the outer wall of the gas pump body 22.

[0039] Specifically, as shown in Figure 7 , in this case, the gas pump body 22 is directly installed in the containing cavity 4 in the soft shell 1. The end of the first protruding structure is in contact with the outer wall of the gas pump body 22. For example, if the gas pump body 22 is a cylindrical gas pump, the first protruding structures on the inner wall of the soft shell 1 can be uniformly distributed to ensure that the gas pump body 22 can be damped in all directions.

[0040] Furthermore, the air source assembly includes an air pump body 22 and a rigid housing 21, and the outer wall of the air source assembly is the outer wall of the rigid housing 21.

[0041] Specifically, such as Figure 1 As shown, in this configuration, the air pump body 22 is first installed inside the rigid housing 21, and then the air source assembly with the rigid housing 21 is installed in the receiving cavity 4 inside the flexible housing 1. The end of the first protruding structure abuts against the outer wall of the rigid housing 21. The rigid housing 21 can be made of materials such as metal or plastic, serving to protect the air pump body 22 and also providing a more stable support surface for the flexible housing 1.

[0042] In a preferred embodiment, the fixing part is a first through hole 8 provided on the outer wall of the flexible shell 1, and the first connector passes through the first through hole 8 to fix the flexible shell inside the vehicle seat.

[0043] Alternatively, please refer to Figure 5 As shown, the first connector is a cable tie 9, which passes through the first through hole 8. The cable tie 9 is also connected to a matching rivet that cooperates with the cable tie 9 to fix the soft shell 1 inside the vehicle seat.

[0044] In a preferred embodiment, the outer wall of the flexible housing 1 is provided with a second connecting member perpendicular to the outer wall of the flexible housing 1.

[0045] Optionally, the second connector is a rivet 10, which can directly engage with the corresponding structure on the vehicle seat to achieve the installation and fixation of the soft shell 1.

[0046] Furthermore, the second connector and the flexible housing 1 are either integrally formed or separately configured.

[0047] Optionally, such as Figure 7 As shown, when the second connector (tack 10) and the flexible housing 1 are integrally formed: during the manufacturing process, the tack 10 and the flexible housing 1 are integrally formed, which can directly cooperate with the corresponding structure on the vehicle seat to achieve installation and fixation.

[0048] Optionally, such as Figure 8 As shown, when the rivet 10 and the flexible housing 1 are separate components: the flexible housing 1 has a reserved mounting hole for installing the rivet 10 during the manufacturing process. The separate rivet 10 is passed through the reserved mounting hole of the flexible housing 1. When the components are separate, the rivet 10 has a limiting structure 101 that protrudes radially outward on the side near the air source assembly. The limiting structure 101 is used to hold the rivet 10 in the reserved mounting hole to achieve connection and fixation with the flexible housing 1.

[0049] In a preferred embodiment, the soft shell 1 is a one-piece structure or a split structure.

[0050] Further, when the soft shell 1 is a one-piece structure, a first opening 15 is reserved on the soft shell 1 for communication with the accommodating cavity 4.

[0051] Further, when the soft shell 1 is a split structure, a sealing element 13 is arranged at the split connection.

[0052] Optionally, as shown in Figure 5 , 6 when the soft shell 1 is a one-piece structure: the soft shell 1 is a continuous structure as a whole without any detachable part. When installing the gas source assembly, the gas source assembly can be put into the accommodating cavity 4 through the reserved first opening 15. For example, the soft shell 1 proposed in the embodiment is a structure similar to a cuboid, so it is formed as a whole in the manufacturing process without any splicing place.

[0053] Optionally, as shown in Figure 1 , 7 when the soft shell 1 is a split structure: the soft shell 1 is composed of multiple parts and can be arranged as an upper-lower split structure, in which case the soft shell 1 can be divided into an upper shell 11 and a detachably connected lower shell 12, or arranged as a left-right split structure. The split structures can be connected through gluing, adhesive tape, mechanical splicing, buckling, bolts or other ways. When the adhesive tape is used, the adhesive tape is the sealing element 13. When installing the gas source assembly, the split structures can be first detached, then the gas source assembly is put into them, and finally the parts are connected.

[0054] Specifically, as shown in Figure 10 when the mechanical splicing is used, a splicing protrusion 111 can be formed on the side of the upper shell 11 close to the lower shell 12, so that the side of the lower shell 12 close to the upper shell 11 needs to be adaptively configured with a splicing groove matched with the shape of the splicing protrusion 111. The splicing protrusion 111 can be clamped in the splicing groove to achieve mechanical splicing. A sealing element 13 can be sleeved at the splicing place to prevent impurities such as dust and moisture from entering the accommodating cavity 4. The sealing element 13 can be a rubber sealing ring, a sealing rubber strip, etc. For example, a rubber sealing ring can be installed at the splicing place of the two parts of the soft shell 1, which is compressed when the two parts are connected to form a seal, or the two parts of the soft shell 1 can be pasted together with a sealing rubber strip.

[0055] In a preferred embodiment, the first protruding structure comprises at least one buffer layer 14 radially arranged along the soft shell 1, the buffer layer 14 has a through hole in the center for the gas source assembly to pass through, and the buffer layer 14 is sleeved outside the gas source assembly and abuts against the outer wall of the gas source assembly.

[0056] Specifically, as shown in Figure 8 The buffer layer 14 can be integrally formed with the soft shell 1 or selected as a separate structure, the size of the buffer layer 14 is adapted to the size of the inner wall of the soft shell 1, the buffer layer 14 has a buffer hole 141 in the center which is adapted to the shape of the gas source assembly, and the gas source assembly is arranged in the buffer hole 141, so that the buffer layer 14 can be sleeved outside the gas source assembly, and the buffer hole 141 further extends towards the center of the buffer layer 14 to form a plurality of buffer burrs 142, which tightly abut against the outer wall of the gas source assembly when the buffer layer 14 is sleeved outside the gas source assembly.

[0057] Specifically, the buffer layer 14 can be arranged as one, arranged below the middle of the gas source assembly, or arranged as two, one arranged below the middle of the gas source assembly and the other arranged above the middle of the gas source assembly. When arranged as two, the soft shell 1 has two buffer zones along the axial direction thereof, and the soft shell 1 in each buffer zone extends along the radial direction towards the central axis of the soft shell 1 to form the buffer layer 14.

[0058] Specifically, in the design process of the soft shell 1, one or two buffer zones are arranged along the axial direction thereof, as shown in Figure 7 , arranged as two buffer layers 14. The buffer zone is a part of the soft shell 1, for example, if the soft shell 1 is a cuboid structure, then at the buffer zone, the inner wall of the soft shell 1 can be inwardly convex to form a buffer layer 14 with a circular buffer hole 141 in the middle of the outer periphery rectangular shape, and if the soft shell 1 is a cylindrical structure, then a ring-shaped buffer layer 14 can be formed to be sleeved outside the gas source assembly.

[0059] In a preferred embodiment, the first protruding structure further comprises a plurality of protruding columns, the protruding columns comprise a first protruding column 3 and a second protruding column, and the protruding height of the second protruding column is smaller than the protruding height of the first protruding column 3.

[0060] Specifically, the protruding column can be hemispherical, conical or cylindrical in shape, made of the same or different soft material as the soft shell 1, and can be integrally formed with the soft shell 1 or fixed on the inner wall of the soft shell 1 by pasting, injection molding or the like. When the gas source assembly is installed in the accommodating cavity 4, the end of the protruding column should abut against the outer wall of the gas source assembly to achieve the effect of shock absorption and noise reduction.

[0061] Specifically, the soft shell 1 comprises a plurality of mutually connected sub-shells 6, and a plurality of first protruding columns 3 are arranged in sequence on the inner wall of each sub-shell 6 close to the edge side of the sub-shell 6; and a plurality of second protruding columns 5 are arranged in sequence on the inner wall of each sub-shell 6 away from the edge side of the sub-shell 6.

[0062] Specifically, if the soft shell 1 is approximately a cuboid structure, it has sub-shells 6 connected to each other through a transition connecting structure 7, and the sub-shells 6 are rectangular structures, and the transition connecting structure 7 is a circular arc structure connecting the corners of each two sides, the upper top surface and the side surface, and the lower bottom surface and the side surface. For the same sub-shell 6, a plurality of first protruding columns 3 are arranged at the two long sides of the rectangle, and two rows of second protruding columns 5 are arranged between the two rows of first protruding columns 3. By arranging this series of protruding structures, a buffer layer can be formed between the air source assembly and the soft shell 1, effectively absorbing and dispersing the impact force, and effectively isolating the direct contact between the air source assembly and the shell. This design can reduce the direct contact area between the two, thereby reducing friction and wear, and also plays the role of fixing the air pump shell and buffering and absorbing vibration. The internal protrusions are also arranged in the form of high protrusions on both sides and low protrusions in the middle, which can utilize the high protrusions to play a buffering role, and the space between the low protrusions and the high protrusions can reduce airflow transmission and also achieve the effect of reducing noise.

[0063] The principles and implementation manners of the present application are described by using specific examples in the present application, and the above example descriptions are only used to help understand the method and its core idea. The above description is only the preferred implementation manner of the present application, and it should be pointed out that, due to the limitation of language expression, there are infinite specific structures, and for ordinary skilled persons in the technical field, some improvements, refinements or changes can be made without departing from the principles of the present application, and the above technical features can also be combined in an appropriate manner; these improvements, refinements, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the protection scope of the present application.
