[0002] With the development of automobile technology, cars have become an important means of transportation in people's daily lives, and the safety performance of cars has also received increasing attention. In order to ensure the safety of passengers and prevent accidents during driving, airbags are usually installed in cars. When a collision occurs, the airbags inflate and reduce the damage caused to people in the car by the collision through their cushioning capacity.

[0003] With increasing attention to driving safety and the continuous improvement of safety regulations, a new type of airbag has emerged. This prevents the airbag from failing to protect the occupant when the occupant is seated in an abnormal position, and may even cause secondary injuries to the occupant due to the impact force generated by the airbag. This type of airbag has two air chambers, but when inflating the airbag, the gas often cannot be evenly distributed in the two chambers, and the gas re-entry amount and injection speed in the two chambers cannot be guaranteed to be the same. To address this problem, a Y-shaped gas distributor device has been proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0025] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, the embodiment of the present invention provides a Y-shaped gas distributor device, including a main body assembly 101, the main body assembly 101 includes a connecting flange 11, an O-ring 12, a Y-shaped joint body 13, a main sealing ring 14, a safety ring 15, a clamping washer 16, a guide sleeve 17 and two gas flow channels 18;

[0027] Two gas flow channels 18 are symmetrically opened inside the Y-shaped joint body 13. The bottoms of the two gas flow channels 18 are connected. The clamping washer 16, the safety ring 15, and the main sealing ring 14 are installed in order from top to bottom on the upper portion of the inner side wall of the gas flow channel 18. The connecting flange 11 is installed on the bottom of the inner side wall of the gas flow channel 18. The O-ring 12 is located between the connecting flange 11 and the gas flow channel 18. The guide sleeve 17 is installed on the top of the inner side wall of the gas flow channel 18. The outer wall of the O-ring 12 is in contact with the bottom of the inner side wall of the gas flow channel 18 and the outer wall of the connecting flange 11. The guide sleeve 17 is connected to the gas flow channel 18, and the lower surface of the guide sleeve 17 is in contact with the upper surface of the clamping washer 16.

[0028] The connecting flange 11 is installed at the bottom of the distributor and can be connected to the gas outlet of the gas generator and the gas inlet of the Y-shaped connector body 13 respectively;

[0029] By installing the O-ring 12 between the gap between the connecting flange 11 and the Y-shaped joint body 13, gas can be prevented from escaping during inflation;

[0030] The Y-shaped connector body 13 is used as the main body of the entire device, and two gas flow channels 18 are provided inside the Y-shaped connector body 13 so that the gas generated by the gas generator can be respectively injected into the inflation chambers of the two airbags.

[0031] The main sealing ring 14 can seal the entire part to prevent gas from escaping;

[0032] The guide sleeve 17 and the clamping washer 16 can be fastened by the safety ring 15 to prevent other parts from falling out;

[0033] The clamping washer 16 can only deform downward and cannot deform upward. When the connecting conduit of the airbag inflation chamber is inserted to a depth exceeding the clamping washer 16, the clamping washer 16 will clamp the connecting conduit so that the connecting conduit cannot be pulled out, thereby fixing the position of the connecting conduit.

[0034] The guide sleeve 17 can ensure the installation position of the connecting conduit, and the connecting conduit of the inflation chamber can only be installed vertically in the guide sleeve 17.

[0035] In one embodiment, a limiting assembly 301 is installed inside the guide sleeve 17. The limiting assembly 301 includes a slide groove 36, a limiting groove 37, a locking column 33, a connecting rod 34 and a slider 35.

[0036] The sliding groove 36 is symmetrically formed inside the guide sleeve 17 , and the limiting groove 37 is formed on the outer wall of the guide sleeve 17 . Both ends of the connecting rod 34 are fixedly connected to the adjacent surfaces of the locking column 33 and the slider 35 .

[0037] The end of the locking column 33 away from the connecting rod 34 is arc-shaped;

[0038] The locking column 33 and the slider 35 are both slidably connected to the inner side wall of the slide groove 36;

[0039] When the connecting conduit of the inflation chamber is inserted into the guide sleeve 17, the guide sleeve 17 pushes the locking column 33, and the locking column 33 pushes the slider 35 through the connecting rod 34. The slider 35 can support the locking ring 31, and the position of the locking column 33 is limited by the locking ring 31. The position of the connecting conduit can be limited by the locking column 33.

[0040] In one embodiment, the inner wall of the limiting groove 37 is slidably connected with a locking ring 31, and the inner wall of the locking ring 31 is attached to the side of the slider 35 away from the connecting rod 34. The outer wall of the locking ring 31 is symmetrically fixedly connected with two connecting pieces 32, and the two connecting pieces 32 are fixedly connected by bolts. By rotating the bolts in the connecting pieces 32, the two connecting pieces 32 can be brought closer to each other, and the connecting pieces 32 drive the inner diameter of the locking ring 31 to shrink. The locking ring 31 pushes the slider 35, and the slider 35 pushes the locking column 33 through the connecting rod 34, and then the connecting conduit can be supported by the locking column 33 to limit the position of the connecting conduit.

[0041] When the utility model is in operation: the connecting flange 11 connects the gas outlet of the gas generator and the gas outlet of the Y-type joint body 13, the O-ring 12 fills the gap between the connecting flange 11 and the Y-type joint body 13 to prevent the escape of gas, the Y-type joint body 13 is the main part of the entire device, and two gas flow channels 18 are arranged inside so that the gas generated by the gas generator can be flushed into the two inflation chambers from the two gas flow channels 18, the main sealing ring 14 seals the Y-type joint body 13 to prevent the escape of gas during inflation, the safety ring 15 prevents the parts from falling out, and tightens the clamping washer 16 and the guide sleeve 17. The clamping washer 16 can fix the position of the inflation chamber connecting conduit. When the connecting conduit is inserted to a certain depth, the connecting conduit will be stuck by the clamping washer 16 and cannot be pulled out.

[0042] When a vehicle collides, the gas generator produces a large amount of gas. The gas first passes through the connecting flange 11 to the Y-type joint body 13. At the Y-type joint body 13, the gas will be divided into two uniform gas streams. After passing through the main sealing ring 14 and the safety ring 15, the gas finally reaches the connecting conduit fixed with the clamping gasket 16, and then rushes into the two inflation chambers respectively through the connecting conduit.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
