However, in the current technology, the pneumatic connection between the pneumatic attachment and its carrier is relatively complex, difficult to assemble and disassemble, and cannot be completed through simple operations, making it very inconvenient to use. Summary of the Invention

[0004] In order to solve some or all of the above-mentioned technical problems, this application provides a detachable air circuit connection structure and a pneumatic adjustment system for an automotive seat attachment.

[0005] According to a first aspect of this utility model, a detachable air passage connection structure for an automotive seat attachment is provided. The attachment is disposed on the seat, and a pneumatic component for massaging or supporting and adjusting the occupant's body is disposed on the core of the attachment. An air source air passage is disposed on the seat, and a controller controls the air source air passage to exchange airflow with the pneumatic component. The air passage connection structure includes a detachably connected first connecting part and a second connecting part. The first connecting part includes a first air passage, which is connected to the air source air passage / the pneumatic component. The second connecting part includes a second air passage, which is connected to the pneumatic component / the air source air passage. During assembly, the first connecting part / second connecting part is inserted into the second connecting part / first connecting part, and the two are detachably connected. After assembly, the first air passage and the corresponding second air passage are sealed together, realizing air passage communication between the air source air passage and the pneumatic component. During disassembly, the first connecting part / second connecting part is pulled out from the second connecting part / first connecting part, and the two are disassembled and separated.

[0006] Furthermore, when the attachment is disposed on the headrest, the first connecting part is disposed on the headrest or the backrest near the headrest, and the second connecting part is disposed corresponding to the first connecting part and disposed on the attachment; after the first connecting part and the second connecting part are assembled, the air supply air passage is connected to the pneumatic component.

[0007] Furthermore, when the attachment is disposed on the backrest, the first connecting part is disposed on the backrest near the attachment, and the second connecting part is disposed corresponding to the first connecting part and disposed on the attachment; after the first connecting part and the second connecting part are assembled, the air supply air passage is connected to the pneumatic component.

[0008] Furthermore, the first connecting part includes a first carrier, the first air passage is disposed on the first carrier, the first air passage includes at least one first pipe, one end of the first pipe is connected to the air source air passage; the second connecting part includes a second carrier, the second air passage is disposed on the second carrier, the second air passage includes at least one second pipe corresponding to the first pipe, one end of the second pipe is connected to the pneumatic component; when the first connecting part and the second connecting part are assembled, the first pipe is connected to the corresponding second pipe.

[0009] Furthermore, the first carrier has protruding snap-fit ​​edges on both sides; the second carrier has snap-fit ​​parts on both sides that can engage with the snap-fit ​​edges; during assembly, the first connecting part is inserted into the second connecting part, and the two are snapped together and fixed by the engagement of the snap-fit ​​edges and the snap-fit ​​parts; during disassembly, the snap-fit ​​parts are pressed to disengage from the snap-fit ​​edges, and the first connecting part and the second connecting part are separated.

[0010] Furthermore, the clamping part is rotatably connected to the second carrier via a rotating shaft, and an elastic element capable of driving the clamping part to rotate around the rotating shaft is also provided between the clamping part and the second carrier. Under the elastic force of the elastic element, the end of the clamping part away from the elastic element is always clamped on the clamping edge.

[0011] Furthermore, the first carrier has a receiving cavity, and clamping parts are provided on both sides of the receiving cavity and rotatably connected to the first carrier via a rotating shaft. The rotating shaft is provided with an elastic element that can drive the clamping parts to rotate around the rotating shaft. A limiting groove is provided on the outer side of the first carrier corresponding to the clamping parts for the clamping parts to move. Without external force intervention, one end of the clamping part always tends to rotate towards the receiving cavity, and the other end always moves in the limiting groove. The two sides of the second carrier contract inward to form a snap-fit ​​groove. During assembly, the second connecting part is inserted into the receiving cavity, and the two are snapped and fixed by the engagement of the snap-fit ​​groove and the clamping part. During disassembly, the clamping part is pressed to disengage the clamping part from the snap-fit ​​groove, and the second connecting part separates from the first connecting part.

[0012] Furthermore, at least one set of pre-ejection mechanisms is provided in the accommodating cavity.

At this time, the elastic reset member is reset and springs outward to provide auxiliary thrust to the second connecting part, making it easy to pull it out.

[0013] Furthermore, at least one set of auxiliary connecting mechanisms is provided in the accommodating cavity. The auxiliary connecting mechanism includes a first suction body disposed at the bottom of the accommodating cavity and a second suction body disposed on the second carrier corresponding to the first suction body.

For example, when the attachment 1 is set on the headrest 2, a receiving groove 19 can be opened at the top of the backrest 18, and the first connecting part 31 can be installed in the receiving groove 19. A dust cover 17 can also be set outside the receiving groove 19. When in use, the second connecting part 32 is inserted into the receiving groove 19 so that the first connecting part 31 and the second connecting part 32 are detachably connected. It should be noted that in this state, the first pipeline 341 is preferably configured as a straight air transmission channel, which facilitates the insertion and removal of the air connection structure 3. When the attachment 1 is set on the backrest 18, a receiving groove 19 can be opened on the side of the backrest 18. The rest of the process and principle are the same as above, and will not be described in detail here. Example 2:

[0060] In a preferred embodiment, the first carrier 4 has protruding snap-fit ​​edges 41 on both sides, and the snap-fit ​​edges 41 and the first carrier 4 can be integrally formed; the second carrier 5 has snap-fit ​​parts 51 on both sides that can snap-fit ​​with the snap-fit ​​edges 41, and the snap-fit ​​parts 51 are rotatably connected to the second carrier 5 through a rotating shaft 6. An elastic element 7 is also provided between the snap-fit ​​parts 51 and the second carrier 5, which can drive the snap-fit ​​parts 51 to rotate around the rotating shaft 6. The elastic element 7 is preferably a spring. Under the action of the spring, the end of the snap-fit ​​part 51 away from the spring is always snapped onto the snap-fit ​​edges 41.

[0061] During assembly, the first connecting part 31 is inserted into the second connecting part 32, and the two are locked together by the engagement of the locking edge 41 and the locking part 51. During disassembly, the locking part 51 is pressed down at the end near the spring, causing the locking part 51 to rotate around the rotating shaft 6 until it disengages from the locking edge 41, thereby separating the first connecting part 31 from the second connecting part 32. Example 3:

[0062] In a preferred embodiment, the first carrier 4 has a receiving cavity 42, and clamping parts 51 are provided on both sides of the receiving cavity 42 and are rotatably connected to the first carrier 4 via a rotating shaft 6. The rotating shaft 6 is provided with an elastic element 7 that can drive the clamping parts 51 to rotate around the rotating shaft 6. The elastic element 7 is preferably a torsion spring. The outer side of the first carrier 4 is provided with a limiting groove 43 corresponding to the clamping parts 51 for the clamping parts 51 to move. Without external force intervention, one end of the clamping part 51 always tends to rotate towards the receiving cavity 42, and the other end always moves in the limiting groove 43. The second carrier 5 forms a snap-fit ​​groove 40 by contracting inward on both sides.

[0063] During assembly, the second connecting part 32 is inserted into the receiving cavity 42, and the two are locked together by the engagement of the locking edge 41 and the locking part 51. During disassembly, the locking part 51, which is movable in the limiting groove 43, is pressed to make the locking part 51 rotate around the rotating shaft 6 until it disengages from the locking edge 41, thereby separating the second connecting part 32 from the first connecting part 31.

[0064] In a preferred embodiment, at least one set of pre-ejection mechanisms 8 are further provided in the accommodating cavity 42. The pre-ejection mechanism 8 includes a mounting groove 81 formed at the bottom of the accommodating cavity 42 and an elastic reset member 82 disposed in the mounting groove 81. The elastic reset member 82 is preferably a spring. When the second connecting part 32 is assembled with the first connecting part 31, the elastic reset member 82 is compressed in the mounting groove 81. During disassembly, the clamping part 51 is pressed until its end enters the limiting groove 43. At this time, the elastic reset member 82 is reset and springs outward to provide auxiliary thrust to the second connecting part 32, making it easy to pull it out.

[0065] In a preferred embodiment, at least one set of auxiliary connecting mechanisms 9 are further provided in the accommodating cavity 42. The auxiliary connecting mechanism 9 includes a first attracting body 91 disposed at the bottom of the accommodating cavity 42 and a second attracting body 92 disposed on the second carrier 5 corresponding to the first attracting body 91. The first attracting body 91 and the second attracting body 92 have the property of mutual attraction. The first attracting body 91 and the second attracting body 92 can both be magnets, or one of them can be a magnet and the other can be an ferrous metal part or other material that can be magnetically attracted. During assembly, the second connecting part 32 is inserted into the accommodating cavity 42, and the second attracting body 92 attracts the first attracting body 91, which plays an auxiliary connecting role for the first connecting part 31 and the second connecting part 32. Example 4:

[0066] The first carrier 4 has a T-shaped insertion slot 44 along its own length direction. The two sides of the first carrier 4 form overlapping platforms 45 corresponding to the T-shaped insertion slot 44. The top of the overlapping platform 45 has a movable slot 46. An elastic sheet 47 is arranged in the movable slot 46 along the length direction of the T-shaped insertion slot 44. One end of the elastic sheet 47 is a fixed end that is connected and fixed to the overlapping platform 45, and the other end is a free end. The free end is bent to form a clamping part 51. Without external force intervention, the clamping part 51 always has a tendency to move away from the movable slot 46.

[0067] The second carrier 5 is provided corresponding to the T-shaped insertion slot 44, and the second carrier 5 has locking edges 41 on both sides that can engage with the locking part 51.

[0068] During assembly, the second connecting part 32 is inserted into the T-shaped insertion slot 44, and the two are locked together by the engagement of the locking edge 41 and the locking part 51. During disassembly, the second connecting part 32 is pulled outward, and the locking part 51 is forced to move downward under the action of external force until it disengages from the locking edge 41, thereby separating the first connecting part 31 from the second connecting part 32.

[0069] In a preferred embodiment, a mounting platform 48 is provided in the movable groove 46, and an elastic sheet 47 is disposed on the mounting platform 48. One end of the elastic sheet 47 is fixedly connected to the mounting platform 48, and the other end always tends to move away from the mounting platform 48. The top surface of the mounting platform 48 is a sloping surface. A reset member 49 is also provided on the mounting platform 48. The reset member 49 is disposed below the elastic sheet 47, specifically below the clamping part 51. The reset member 49 can be configured as a reset sponge, a reset spring, or an elastomer made of silicone material.

[0070] When disassembling the first connecting part 31 and the second connecting part 32, the second connecting part 32 is pulled outward. Under the action of external force, the clamping part 51 is forced to move downward and squeeze the reset member 49 until it is disengaged from the locking edge 41. The first connecting part 31 and the second connecting part 32 are separated. After that, the reset member 49 naturally rebounds and assists in lifting the elastic piece 47 to reset it. Example 5:
