Technical Field

[0001] The utility model belongs to the technical field of automobile seat accessories, and particularly relates to an integrated pump valve for an air lumbar support of an automobile seat. Background Art

[0002] The air lumbar support of an automobile seat is composed of multiple airbags, which are usually arranged in the middle and lower parts of the backrest of the automobile seat and occupy corresponding space according to the number of airbags. The more airbags there are, the larger the adjustment range of support is. Similarly, the massage function can also be realized by inflating and deflating the airbags. The more airbags there are, the better the massage effect is.

[0003] At present, the airbags of the air lumbar support are developing in the direction of more quantity, which requires more solenoid valves to control these airbags. Of course, an air pump for inflation is also indispensable. Since the air lumbar support already occupies part of the space in the middle and lower parts of the backrest, the space left for the air pump and solenoid valves is already quite limited, and now more solenoid valves are needed. The existing arrangement form with the air pump and solenoid valves set separately has the disadvantage of large space occupation because the air pipe between the air pump and solenoid valves also occupies space and the air pump and solenoid valves respectively require fixing structures, and it is difficult to adapt to the development trend of more and more airbags in the air lumbar support. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an integrated pump valve for an air lumbar support of an automobile seat to solve the technical problem of large space occupation of the existing arrangement form with the air pump and solenoid valves set separately for the space in the middle and lower parts of the backrest of the automobile seat.

[0005] To solve the above technical problem, the utility model provides an integrated pump valve for an air lumbar support of an automobile seat, including: an air pump, with a plurality of air pump air outlets provided at the pump head thereof; a plurality of solenoid valves, the solenoid valve air inlets of which are adapted to the air pump air outlets to dock with the air pump air outlets; a U-shaped yoke, with a plurality of pairs of mounting grooves opened on the upper protruding part and the lower protruding part thereof to commonly fix the plurality of solenoid valves in the U-shaped yoke; the U-shaped yoke is adapted to be mounted on the pump head of the air pump through the mounting holes thereon to fix the solenoid valves on the air pump.

[0006] Further, a plurality of pairs of the mounting grooves are spaced apart and opened in the U-shaped yoke to space apart the solenoid valves.

[0007] Further, the distance between the upper protruding part and the lower protruding part of the U-shaped yoke is adapted to the length of the solenoid valve, and the shape of the notch of the mounting groove is adapted to the valve body of the solenoid valve so that the mounting grooves respectively fit the valve head and the valve tail of the solenoid valve.

[0008] Further, a receiving groove is opened at the pump tail of the air pump to arrange an air pump circuit board.

[0009] Furthermore, a one-way valve is provided between the air outlet of the air pump and the air inlet of the solenoid valve.

[0010] Furthermore, a sealing ring is provided in the air inlet of the solenoid valve.

[0011] Furthermore, the solenoid valve air outlet of the solenoid valve is barb-shaped.

[0012] Furthermore, the air pump fixed with a plurality of the electromagnetic valves is covered by a head cover and a tail cover; the head cover is provided with air pipe holes corresponding to the number of the electromagnetic valves.

[0013] Furthermore, a solenoid valve circuit board is provided on one side of the U-shaped yoke; and a solenoid valve circuit board supporting rib is provided inside the head cover.

[0014] Furthermore, a plurality of silencer cotton stoppers are provided in the head cover shell to press the silencer cotton against the exhaust ports of each solenoid valve.

[0015] The beneficial effect of the utility model is that the utility model aims to solve the technical problem that the existing arrangement form in which the air pump and the solenoid valve are separately arranged occupies a large space in the middle and lower part of the backrest of the automobile seat. The automobile seat pneumatic lumbar support uses an integrated pump valve to fix multiple solenoid valves together on the u-shaped yoke, and the air inlet of the solenoid valve is adapted to the air outlet of the air pump. The u-shaped yoke can be used to directly install it on the air pump, eliminating the air pipe between the solenoid valve and the air pump, and the integrated pump valve only needs one fixed structure in the backrest. Compared with the existing air pump and solenoid valve that need separate fixed structures, the space in the middle and lower part of the backrest can be greatly freed up.

In at least one embodiment, there are three electromagnetic valves 200.

[0032] The integrated pump valve for the pneumatic lumbar support of this vehicle seat fixes multiple solenoid valves 200 together on a large U-shaped yoke 300, and the air inlet 210 of the solenoid valve is adapted to the air outlet 110 of the air pump. It can be directly installed on the air pump 100 by using the U-shaped yoke 300, eliminating the air pipe between the solenoid valve 200 and the air pump 100. Moreover, this integrated pump valve only requires one fixing structure in the backrest. Compared with the existing air pump and solenoid valve that respectively require fixing structures, the space in the middle and lower parts of the backrest can be greatly liberated overall.

[0033] After fixing the solenoid valves 200 together in the U-shaped yoke 300, in order to dissipate the heat generated by the solenoid valves 200 in operation to the surrounding in time, as Figure 2 shown, several pairs of the installation grooves 330 are spacedly arranged in the U-shaped yoke 300 to space apart the solenoid valves 200.

[0034] Furthermore, in order to strengthen the heat dissipation to the surrounding, as Figure 2 shown, the distance between the upper protruding part 310 and the lower protruding part 320 of the U-shaped yoke 300 is adapted to the length of the solenoid valve 200, and the shape of the notch of the installation groove 330 is adapted to the valve body of the solenoid valve 200, so that the installation grooves 330 respectively fit the valve head and valve tail of the solenoid valve 200, thereby leading out the heat from both ends of each solenoid valve 200 and introducing it into the U-shaped yoke 300, allowing the heat to be quickly dissipated to the surrounding through the larger-area U-shaped yoke 300.

[0035] As Figure 1 shown, a receiving groove is opened at the pump tail of the air pump 100 to arrange the air pump circuit board 120.

[0036] As Figure 1 shown, a one-way valve 410 can be provided between the air outlet 110 of the air pump and the air inlet 210 of the solenoid valve.

[0037] As Figure 3 shown, a sealing ring 420 can be provided in the air inlet 210 of the solenoid valve.

[0038] As Figure 2 shown, the air outlet 220 of the solenoid valve 200 can be barbed for quick insertion of the air pipe.

[0039] As Figure 1 shown, the air pump 100 with several solenoid valves 200 fixed thereon can be covered by a head cover 500 and a tail cover 600; combined with Figure 4 , air pipe through holes 510 corresponding to the number of solenoid valves 200 are opened on the head cover 500.

[0040] As Figure 1 shown, an electromagnetic valve circuit board 700 can be provided on one side of the U-shaped yoke 300; combined with Figure 4 The head cover 500 may be provided with a solenoid valve circuit board support rib 520 to limit and support the solenoid valve circuit board 700.

[0041] like Figure 4 As shown, a plurality of silencer cotton blocks 530 may be provided in the head housing 500 to hold the silencer cotton against the exhaust port of each solenoid valve 200. In at least one embodiment, the solenoid valve 200 is a solenoid valve having an air path corresponding to the solenoid valve air inlet 210, the solenoid valve air outlet 220, and the exhaust port.

[0042] In summary, the pneumatic lumbar support for the automobile seat uses an integrated pump valve to fix multiple solenoid valves 200 together on a large U-shaped yoke 300, and the solenoid valve air inlet 210 is adapted to the air pump outlet 110. The U-shaped yoke 300 can be used to directly install it on the air pump 100, eliminating the air pipe between the solenoid valve 200 and the air pump 100, and the integrated pump valve only needs one fixed structure in the backrest. Compared with the existing air pump and solenoid valve that require separate fixed structures, the space in the middle and lower parts of the backrest can be greatly freed up.
