[0032] As Figures 1-9 shown, an airbag type adjustable height armrest riser includes a main body pad 1 mounted on an armrest, and an inflation switch assembly 200, a deflation switch assembly 300, an adjustable airbag 2 and a hand pad 3 provided on the main body pad 1. An installation groove 4 is formed at the upper end of the main body pad 1. The adjustable airbag 2 is disposed in the installation groove 4, and the hand pad 3 covers the installation groove 4.

[0033] A guide air pipe 5 is connected to the lower end of the adjustable airbag 2. The inflation switch assembly and the deflation switch assembly are communicatively provided on the extending path of the guide air pipe 5. The inflation switch assembly can inflate the adjustable airbag 2 through the guide air pipe 5 under an external force to raise the height of the hand pad 3, and the deflation switch assembly can deflate the adjustable airbag 2 through the guide air pipe 5 under an external force to lower the height of the hand pad 3.

[0034] In the above technical solution, the main body pad and the hand pad are designed separately, and an adjustable airbag is arranged in the mounting groove of the main body pad. The hand pad covers the mounting groove, and the main body pad is installed on the armrest. The hand pad can provide support for the user's arm. When the height of the hand pad needs to be adjusted, the user can inflate the adjustable airbag through the inflation switch assembly. After the airbag inflates, the hand pad is lifted, and the height of the hand pad is increased; if the increased height is felt to be inappropriate or the height-enhancing pad is to be restored to its initial state, the user can deflate the adjustable airbag through the deflation switch assembly. The airbag is deflated, and the height of the hand pad is reduced, thereby making the height of the armrest height-enhancing pad adjustable, which is convenient for users to adjust according to their own needs, thereby improving user satisfaction and comfort.

[0035] Furthermore, the side ends of the main body pad 1 are sequentially constructed with a first accommodating groove 6, a second accommodating groove 7 and a third accommodating groove 8 that are connected along the extension direction of the air duct 5. The air duct 5 is arranged in the first accommodating groove 6, and the two side edges of the first accommodating groove 6 are constructed with flanges 9; the inflation switch assembly is fixedly arranged on the third accommodating groove 8; the deflation switch assembly is adapted to be installed on the second accommodating groove 7 and is respectively connected to the air duct 5 and the inflation switch assembly. In this technical solution, the inflation switch assembly is shaped like a squeeze ball, and the air duct, inflation switch assembly and deflation switch assembly are respectively embedded in the first accommodating groove, the second accommodating groove and the third accommodating groove, which can effectively prevent radial detachment. The flange can prevent the air duct from detaching from the side, and at the same time make the air duct hidden, which is more simple and beautiful; the surfaces of the inflation switch assembly and the deflation switch assembly are not hidden, which is convenient for user operation. The inflation switch assembly is fixed on the main pad to prevent it from detaching from the side during operation, and the two sides of the deflation switch assembly are respectively connected to the air duct and the inflation switch assembly, so that it will not detach from the side and is easy to disassemble and assemble.

[0036] Furthermore, the inflation switch assembly includes a silicone ball disposed on the third receiving groove 8, forming an inflation chamber within the silicone ball. A first air inlet pipe 10 communicating with the outside is provided on the inner wall of the silicone ball, and a first one-way air inlet valve 11 is provided within the first air inlet pipe 10. A first air outlet pipe 33 communicating with the inflation chamber and the deflation switch assembly is provided on the outer wall of the silicone ball. A through hole 12 corresponding to the first air inlet pipe 10 is provided at the bottom of the third receiving groove 8. In this technical solution, when the silicone ball is pressed, the air in the inflation chamber flows from the first air outlet pipe to the deflation switch assembly, and then to the air guide pipe and the adjustable airbag for inflation. External air can enter the inflation chamber through the first air inlet pipe for replenishment. The provision of the first one-way air inlet valve allows air to enter the inflation chamber only from the outside, preventing internal air from escaping through the first air inlet pipe.

[0037] Further, the silica gel ball includes a silica gel upper shell 13 and a silica gel lower shell 14 which are butted against each other, and a first return spring 15 is arranged between the silica gel upper shell 13 and the silica gel lower shell 14. In this technical solution, the silica gel ball is divided into a silica gel upper shell and a silica gel lower shell, which is convenient for disassembly, assembly and maintenance. At the same time, a first return spring is arranged between the silica gel upper shell and the silica gel lower shell, so that the silica gel ball can quickly recover after being pressed, improving the inflation efficiency.

[0038] Further, both the silica gel upper shell 13 and the silica gel lower shell 14 include a bulging portion 16 and a connecting portion 17 formed on the edge of the bulging portion 16. A plurality of connecting holes 18 are arranged on the connecting portion 17, and a clamping groove 19 adapted to the connecting portion 17 is formed on the outside of the third receiving groove 8; a plastic sheet 20 is arranged in the main body pad 1, and a plurality of screw posts 21 are formed on the plastic sheet 20. The plurality of screw posts 21 extend out of the clamping groove 19 and are arranged corresponding to the plurality of connecting holes 18;

[0039] The first air inlet pipe 10 and the first air outlet pipe 33 are arranged on the silica gel lower shell 14. The silica gel lower shell 14 is arranged in the third receiving groove 8, and the silica gel upper shell 13 is fixedly attached to the outside of the silica gel lower shell 14.

[0040] In the above technical solution, the silica gel upper shell and the silica gel lower shell are bonded together by heat melting, and the structure is stable. Then, they are fixedly installed on the main body pad through the plastic sheet. Specifically, the bulging portion is adapted to be installed in the corresponding third receiving groove, and the connecting portion is installed corresponding to the clamping groove, which can effectively prevent radial disconnection; in addition, the plurality of connecting holes of the connecting portion correspond to the plurality of screw posts of the plastic sheet. After screwing in screws or bolts, it can effectively prevent the silica gel upper shell and the silica gel lower shell from disengaging from the side, playing a good stabilizing role.

[0041] Further, the air release switch assembly includes an air release switch main body 22. On both sides of the air release switch main body 22, there are respectively arranged a second intake pipe 31 inserted and matched with the first outlet pipe 33, and a second outlet pipe 32 inserted and matched with the air guide pipe 5. An air ventilation cavity communicating with the second intake pipe 31 and the second outlet pipe 32 is formed inside the air release switch main body 22. At the upper end of the air release switch main body 22, a pressing groove 23 is constructed. In the middle of the bottom of the pressing groove 23, there is an air vent 24; an air release button is arranged in the pressing groove 23, which includes a pressing piece 25, a connecting column 26, and a silica gel film 27 connected and arranged from top to bottom. The lower end of the connecting column 26 extends into the air vent 24 and forms a gap with the side wall of the air vent 24. The silica gel film 27 is located in the air ventilation cavity and closes the lower end of the air vent 24. A second return spring 28 is arranged between the pressing piece 25 and the pressing groove 23 on the outside of the connecting column 26. In this technical solution, the air in the inflation cavity enters the air ventilation cavity through the second intake pipe, and then comes out from the second outlet pipe into the air guide pipe for inflation. At this time, the silica gel film blocks the lower end of the air vent, making the air ventilation cavity relatively closed, and the air will not overflow; when deflation is required, the air release button is pressed, the silica gel film moves downward, and the air in the air ventilation cavity overflows from the air vent along the gap from the upper end of the air vent, and the air in the airbag enters the air ventilation cavity along the air guide pipe, thereby achieving the effect of deflation. In addition, the setting of the second return spring can act on the pressing piece. After the user releases the hand, the air release button rebounds as a whole to restore, and the silica gel film re-blocks the lower end of the through hole, playing a role in sealing.

[0042] Further, a boss 29 is arranged at the bottom of the pressing groove 23 around the air vent 24, and the boss 29 is located inside the second return spring 28. In this technical solution, the setting of the boss can prevent the pressing piece from pressing excessively and causing the spring to fail, playing a role in protecting the spring.

[0043] Further, a second one-way intake valve 30 is arranged in the second intake pipe 31. In this technical solution, the setting of the second one-way intake valve can prevent the gas entering the air ventilation cavity from flowing back into the inflation cavity, improving the inflation efficiency.

[0044] It should be noted here that the two fixing holes 100 in the main body pad can be used for fixed assembly with both sides of the adjustable airbag, improving the stability of the airbag during the bulging process.

[0045] In this specific embodiment, in view of the problem that the existing armrest heightening pads cannot be adjusted in height according to the user's body type, the above solution divides the armrest heightening pad into a main pad and a hand pad. An adjustable airbag, an inflation switch assembly, and a deflation switch assembly are provided on the main pad. The hand pad is arranged above the adjustable airbag. When the user presses the silicone ball, the air in the inflation cavity can be continuously delivered into the airbag for inflation. The inflated airbag can lift the height of the hand pad. When the user presses the deflation button, the air in the airbag enters the ventilation cavity through the air duct for deflation. As the airbag deflates, the height of the hand pad decreases, thereby effectively realizing the adjustable height of the armrest heightening pad and solving the problem that users with different body types have different height requirements for the heightening pad.
