It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0029] In the embodiments of the present application, Figure 1-3As shown, the throttle valve may include: a throttle valve cavity 3, a gear through hole seat 5, and a rotating shaft 8. The throttle valve cavity 3 is provided with an intake channel, an exhaust channel and a mounting cavity, and the intake channel and the exhaust channel are respectively connected to the mounting cavity; the gear through hole seat 5, the rotary seal is arranged in the mounting cavity, and the intake channel and the exhaust channel are respectively separated into an intake cavity 13 and an exhaust cavity 12; the gear through hole seat 5 is provided with an air guide cavity with a top opening, and the side wall of the gear through hole seat 5 is provided with a plurality of pairs of air guide holes 18 arranged oppositely for connecting the intake cavity 13, the exhaust cavity 12 and the air guide cavity; the size of each pair of air guide holes 18 is different, such as Figure 6 As shown; a rotating shaft 8 is rotatably sealed in the air guide cavity, and an O-ring 7 for sealing the air guide cavity is sleeved on the rotating shaft 8; and an air guide channel 14 for connecting or closing any pair of air guide holes 18 is opened on the rotating shaft 8.

[0030] In some cases, the throttle valve cavity 3 is open at the lower part of the intake channel and the exhaust channel due to problems with the injection mold. In order to close the opening, a steel ball 2 is used here for interference fit and is encapsulated with sealant to maintain sealing.

[0031] The throttle valve provided in this embodiment controls the size of the airflow and realizes throttling by rotating the rotating shaft 8 to select the airflow aperture of the air inlet chamber 13 and the exhaust chamber 12, that is, to select which pair of air guide holes 18 the air guide channel 14 of the rotating shaft 8 is connected to. The smaller the aperture, the greater the stiffness of the airbag shock-absorbing seat, and the larger the aperture, the smaller the stiffness of the airbag shock-absorbing seat, so that the seat stiffness can be adjusted quickly and the user's operating experience can be improved.

[0032] In some embodiments, the centers of the pairs of air guide holes 18 are on the same horizontal line, and the diameters of the pairs of air guide holes 18 are arranged in descending order, and the diameter of the air guide channel 14 is the same as the largest diameter of the air guide holes 18. Sequential drainage is conducive to users to quickly adjust according to their needs and find the appropriate use requirements.

[0033] In this embodiment, there are four pairs of air guide holes 18, and the gear through-hole seat 5 and the throttle valve cavity 3 are sealed by the cavity sealing ring 4 installed in the installation cavity. The cavity sealing ring 4 and the gear through-hole seat 5 isolate the throttle valve cavity 3 into independent air intake chamber 13 and exhaust chamber 12. The airflow can only be guided to the exhaust chamber 12 through the air guide holes 18 on the air intake side of the gear through-hole seat 54 pairs of air guide holes 18, and the sizes of the four pairs of air guide holes 18 are 0.4mm, 0.64mm, 1mm, and 1.6mm, and the cross-sectional areas of the four through holes are superimposed by 2.5 times. Each pair of air guide holes 18 is arranged opposite to each other, and the two air guide holes 18 of each pair of air guide holes 18 have the same size.

[0034] In some embodiments, a throttle valve fixing seat 6 is also included, and a through hole is provided on the bottom plate of the throttle valve fixing seat 6. The throttle valve cavity 3 is fixedly arranged at the bottom of the throttle valve fixing seat 6, and the top of the gear through hole seat 5 extends out of the through hole arrangement. The inner cavity side wall of the throttle valve fixing seat 6 is provided with a number of gear positioning notches 1916 equal to the number of pairs of air guide holes 18, and the lower part of each gear positioning notch 1916 is respectively opposite to the intake side of the corresponding pair of air guide holes 18. By providing a number of gear positioning notches 1916 equal to the number of pairs of air guide holes 18 on the inner cavity side wall of the throttle valve fixing seat 6, as shown in FIG. Figure 4 It is convenient to quickly adjust the rotating shaft 8 and select the air flow apertures of the air inlet cavity 13 and the air outlet cavity 12 to control the air flow size and realize throttling.

[0035] In some embodiments, the throttle position switch 9 is further included. The throttle position switch 9 is fixed on the rotating shaft 8, and a protrusion 20 corresponding to the position positioning notch 1916 is provided on the throttle position switch 9. Fig.10 As shown. The protrusion 20 and the air intake side of the air guide channel 14 are on the same straight line in the vertical direction. The throttle position switch 9 facilitates the rotation of the rotating shaft 8, and also facilitates the cooperation between the protrusion 20 and the position positioning notch 1916 to quickly select the air flow aperture of the air intake chamber 13 and the exhaust chamber 12 to control the air flow size and achieve throttling.

[0036] In some embodiments, it also includes a throttle valve outer frame fastener 11 and a throttle valve gear knob 10, the throttle valve outer frame fastener 11 is fastened to the throttle valve fixing seat 6, the throttle valve gear knob 10 is fastened to the throttle valve gear switch 9, and the throttle valve outer frame fastener 11 is provided with a gear mark at a position opposite to the air guide hole 18 on the intake side of each air guide hole 18, and the throttle valve gear knob 10 is provided with a pointer for indicating the gear mark, and the pointer is in the same straight line with the intake side of the air guide channel 14 in the vertical direction. The gear mark can be 1st gear, 2nd gear, 3rd gear and 4th gear, or other marks that are easy to distinguish. It can be quickly adjusted to a suitable gear.

[0037] In order to further improve the time of adjusting the gear position, an arc groove 21 is provided on the edge of the throttle gear position knob 10 opposite to the pointer, and a limit column 15 is provided on the lower surface of the throttle outer frame fastener 11, so that after the throttle outer frame fastener 11 and the throttle gear position knob 10 are buckled, the rotation of the arc groove 21 of the throttle gear position is limited by the limit column 15, and correspondingly, the pointer can only rotate in the area with gear positions. Figure 8-9 shown.

[0038] In some embodiments, the throttle valve fixing seat 6 is provided with a positioning boss 17, and the throttle valve cavity 3 is provided with a positioning notch 19. Figure 5 and 7 As shown, the throttle valve fixing seat 6 and the throttle valve cavity 3 are pre-positioned by the cooperation of the positioning boss 17 and the positioning notch 19. The pre-positioning fastening facilitates the assembly of the bolt 1.

[0039] This embodiment also provides an airbag seat, comprising any of the above-mentioned throttle valves. By installing the throttle valve, the stiffness of the airbag seat can be quickly adjusted, thereby improving the user's operating experience.

[0040] This embodiment also provides a car, comprising the above-mentioned airbag seat. By installing the airbag seat, the rigidity of the airbag seat can be quickly adjusted, thereby improving the user's operating experience.

[0041] The beneficial effects that the airbag seat and automobile disclosed in this application may bring include but are not limited to: by rotating the throttle gear knob to select the airflow aperture of the air inlet chamber and the exhaust chamber, the airflow size is controlled to achieve throttling. For example, select gear 1 with an aperture of 0.4mm, gear 2 with an aperture of 0.64mm, gear 3 with an aperture of 1mm, and gear 4 with an aperture of 1.6mm. The smaller the gear with the aperture, the slower the airbag seat exhausts and the greater the stiffness of the airbag shock-absorbing seat. The larger the gear with the aperture, the faster the airbag seat exhausts and the smaller the stiffness of the airbag shock-absorbing seat, so as to achieve rapid adjustment of the seat stiffness and improve the user's operating experience.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
