Description

Technical Field

[0001] The utility model belongs to the technical field of automobile seats, and in particular relates to an inflation and deflation control element for a seat airbag. Background Art

[0002] In order to improve the comfort of drivers and passengers, modern cars will make some changes to car seats, such as adjusting the height or angle of the seat. Some of these seat adjustments require the inflation and deflation of seat airbags. The seat airbags are generally connected to the vehicle's air pump, which inflates the seat airbags to adjust the car seat to a satisfactory level to maintain the stability and comfort of the seat.

[0003] Most of the seat airbags in existing vehicles are adjusted manually. The adjustment switch is generally set on the connecting pipe between the air pump and the seat airbag. The user controls the connection of the pipe through the adjustment switch to achieve inflation and deflation of the seat airbag. However, the adjustment switch currently on the market has a simple structure. After the adjustment switch is installed on the air pump air pipe, air leakage may occur at the connection position between the air pump and the adjustment switch, reducing the air volume of the air pipe, causing the expansion speed of the seat airbag to slow down. At the same time, air leakage noise will be generated, which is not conducive to safe driving and cannot ensure long-term seat comfort. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example:

[0029] See also Figure 1 - Figure 5 As shown, a seat airbag inflation and deflation control element comprises:

[0030] A mounting base 1, a mounting block 2 is clamped on the bottom of the mounting base 1, an air channel 3 is provided on the side wall of the mounting block 2, and an air inlet head 4 is clamped on one of the air channels 3;

[0031] A pressing block 5 is provided above the mounting base 1, and a button 6 is fixedly connected to the top of the pressing block 5, and the button 6 is hinged to the mounting base 1;

[0032] An air outlet pipe 7 is inserted into the mounting block 2 and abuts against the pressing block 5. A spring 9 is sleeved on the upper end of the air outlet pipe 7, and an air outlet hole 15 is opened on the air outlet pipe 7;

[0033] An air intake pipe 8 is inserted into the mounting block 2 and abuts against the pressing block 5. A spring 9 is sleeved on the upper end of the air intake pipe 8, and an air intake hole 13 is opened on the air intake pipe 8;

[0034] The first sealing ring 10 is provided in two groups, which are respectively sleeved on the outlet pipe 7 and the inlet pipe 8, and each group has two first sealing rings. A retaining ring 11 is provided between the two first sealing rings 10 in each group. The retaining ring 11 is fixedly mounted on the mounting block 2. A connecting hole 12 is opened on the retaining ring 11 on the outer side of the inlet pipe 8;

[0035] A second sealing ring 14, which is sleeved on the air inlet pipe 8;

[0036] The air inlet hole 13 is provided at the upper end of the air inlet pipe 8 . When the spring 9 is not compressed, the air inlet hole 13 is located between the first sealing ring 10 and the second sealing ring 14 .

[0037] The air outlet 15 is provided in the middle of the air outlet pipe 7 . When the spring 9 is not compressed, the air outlet 15 is located between the two first sealing rings 10 , that is, the retaining ring 11 seals the air outlet 15 .

[0038] As can be seen from the above, the lower ends of the outlet pipe 7 and the lower ends of the outlet pipe 8 are connected to the seat airbag through a three-way pipe, and then the air inlet head 4 is connected to the car air pump. The user presses the button 6 to compress the spring 9 to drive the outlet pipe 7 or the air inlet pipe 8 to move, thereby realizing the air intake or exhaust of the seat airbag. The first sealing ring 10, the retaining ring 11 and the second sealing ring 14 can effectively increase the sealing of the outlet pipe 7 and the air inlet pipe 8, thereby avoiding air leakage during the inflation and deflation process.

[0039] The air intake head 4 is arranged on the air duct 3 corresponding to the air intake pipe 8, and the air intake head 4 is arranged opposite to the connecting hole 12. When the air intake hole 13 is connected to the connecting hole 12, the air intake head 4 can inflate the seat airbag through the connecting hole 12 and the air intake hole 13, and the air ducts 3 on the mounting block 2 are not connected to each other.

[0040] One end of the spring 9 abuts against the side wall of the trachea end and the other end abuts against the mounting block 2. The spring 9 pushes the outlet pipe 7 and the inlet pipe 8 upward based on the mounting block 2, so as to prevent the outlet pipe 7 from moving downward and causing the outlet hole 15 to be connected to the outside world. At the same time, it can also prevent the inlet pipe 8 from moving downward and causing the inlet hole 13 to be connected with the connecting hole 12. When the user presses the button 6, the button 6 drives the pressure block 5 to rotate and squeeze the compression spring 9 downward, so that the outlet pipe 7 or the inlet pipe 8 slides downward to realize air in and out.

[0041] An annular groove is provided on the outer wall of the air intake pipe 8, and the second sealing ring 14 is clamped inside the annular groove, and the second sealing ring 14 abuts against the inner wall of the mounting block 2. The air intake head 4 is connected to the automobile air pump, resulting in a higher air pressure in the chamber between the air intake head 4 and the mounting block 2. At this time, the air flow may flow out from the gap between the mounting block 2 and the air intake pipe 8. The second sealing ring 14 can effectively block the air flow. At the same time, when the air intake pipe 8 does not slide downward to intake air, the air intake hole 13 is between the first sealing ring 10 and the second sealing ring 14. The two sealing rings cooperate to limit the air flow, thereby maintaining the internal air pressure of the seat airbag stable, and will not leak or re-inflate.

[0042] A brass joint 41 is inserted into the end of the air inlet head 4, and a third sealing ring 42 is sleeved on the brass joint. Since the air inlet head 4 and the mounting block 2 are frequently plugged in and out, the inner wall of the air duct 3 may be scratched by the brass joint 41 to produce marks. These marks will affect the sealing performance of the air duct 3 and the air inlet head 4. Therefore, a third sealing ring 42 is sleeved on the brass joint 41. The third sealing ring 42 can block the connecting part between the air duct 3 and the brass joint 41, effectively increasing the airtightness of the air inlet head 4.

[0043] After the user installs the inflation and deflation control component on the air pipe of the car seat airbag, when the user needs to inflate the seat airbag, press the button 6 downward to drive the spring 9 to compress the intake pipe 8, and as the intake pipe 8 moves downward, the air inlet hole 13 on the intake pipe 8 is aligned with the connecting hole 12 on the retaining ring 11. At this time, the air inlet head 4 inflates the seat airbag through the connecting hole 12 and the air inlet hole 13. When the user releases the seat airbag gas, press the other side of the button 6 downward to compress the spring 9 to move the outlet pipe 7 downward. As the outlet pipe 7 moves downward, the outlet hole 15 on the outlet pipe 7 detaches from the first sealing ring 10 and the retaining ring 11 and connects to the outside world. At this time, the internal gas of the seat airbag is discharged to the outside from the outlet hole 13, thereby achieving the deflation of the seat airbag.
