[0003] This utility model addresses the technical problems existing in the prior art by providing a quick-release structure for reusable automotive airbags, thus solving the problem that existing airbag installation structures are difficult to replace or reuse quickly.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a quick-release structure for reusable automotive airbags, comprising:

[0005] Airbag storage cavity;

[0006] The quick-release interface includes a snap-fit ​​interface and two sets of female locking structures. The snap-fit ​​interface is located on the outside of the airbag storage cavity and communicates with the internal chamber of the airbag storage cavity. The two sets of female locking structures are arranged sequentially on the side wall of the snap-fit ​​interface along the circumference of the snap-fit ​​interface. Each set of female locking structures includes a snap-fit ​​groove, a guide groove, and an arc-shaped clearance groove.

The clearance groove is located on the outside of the airbag storage cavity and communicates with the guide groove.

[0007] An airbag is detachably connected to the female locking structure of a quick-release interface. The airbag includes an airbag pouch, a quick-connect connector, and two sets of male locking structures. The airbag pouch is fitted onto one end of the quick-connect connector. The two sets of male locking structures are arranged sequentially along the circumference of the quick-connect connector on the outside of the other end of the quick-connect connector. Each set of male locking structures includes an arc-shaped boss and an elastic damping block. The boss and damping block are sequentially fitted onto the other end of the quick-connect connector along a spiral path and at intervals.

[0008] The beneficial effects of this utility model are:

[0009] 1) By setting a snap-fit ​​interface and two sets of female locking structures on the outside of the airbag storage cavity, and using a combination of snap-fit ​​grooves, guide grooves, and arc-shaped clearance grooves with arc-shaped bosses and elastic damping blocks arranged along a spiral path on the quick connector, the airbag can be quickly installed and removed. During installation, the arc-shaped bosses and damping blocks enter the guide groove through the clearance groove. At this time, the quick connector is rotated, and the bosses and damping blocks move along a spiral path in the guide groove. The quick connector can be further inserted into the snap-fit ​​interface to ensure a tight connection between the quick connector and the airbag storage cavity. Then, as the damping blocks move and embed into the snap-fit ​​groove, the locking between the quick connector and the airbag storage cavity is completed. During removal, simply reverse the rotation of the quick connector to disengage the damping blocks from the snap-fit ​​groove, completing the quick removal.

[0010] 2) In summary, this structure not only improves the efficiency of airbag installation and removal and facilitates repeated use, but also enhances the anti-loosening ability of the connection parts through the design of the spiral path and damping block. In addition, the quick-release structure is simple in design, easy to process and manufacture, effectively reduces production and maintenance costs, and has good economic efficiency and practicality.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, a groove is provided at one end of the quick connector, and a metal pressure ring is embedded inside the groove of the quick connector.

[0013] Furthermore, the opening of the airbag is located between the metal pressure ring and the groove of the quick connector.

[0014] Furthermore, the airbag includes a first fabric and a second fabric, with one side of the first fabric sewn onto one side of the second fabric.

[0015] Furthermore, the seams of the first and second fabrics are coated with a silicone coating.

[0016] The beneficial effect of adopting the above-mentioned further solutions is that while enhancing the airtightness of the airbag, it can also reduce the risk of bursting and rough edges. Attached Figure Description

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] In the field of automotive safety, airbags are key passive safety devices that can inflate rapidly when a vehicle collides to protect occupants. Existing airbag installation structures are difficult to replace or reuse quickly. To address this issue, the inventor has proposed a quick-release structure for reusable automotive airbags.

[0030] The present invention provides the following preferred embodiments.

[0031] like Figures 1-9 As shown, the quick-release structure for a reusable automotive airbag includes:

[0032] Airbag storage chamber 10 (the airbag storage chamber 10 is made of PPS + 40% glass fiber injection molding);

[0033] The quick-release interface includes a snap-fit ​​interface 20 and two sets of female locking structures 30. The snap-fit ​​interface 20 is located on the outside of the airbag storage cavity and is connected to the internal chamber of the airbag storage cavity. The two sets of female locking structures 30 are arranged sequentially on the side wall of the snap-fit ​​interface 20 along the circumference of the snap-fit ​​interface 20. Each set of female locking structures 30 includes a snap-fit ​​groove 301, a guide groove 302, and an arc-shaped clearance groove 303. The guide groove 302 and the snap-fit ​​groove 301 are sequentially and alternately located on the side wall of the snap-fit ​​interface 20 of the airbag storage cavity 10 along a spiral path. The clearance groove 303 is located on the outside of the airbag storage cavity and is connected to the guide groove 302.

[0034] The airbag is detachably connected to the female locking structure 30 of the quick-release interface. The airbag includes an airbag pouch 40, a quick connector 50, and two sets of male locking structures 60. The airbag pouch 40 is fitted onto one end of the quick connector 50. The two sets of male locking structures 60 are arranged sequentially along the circumference of the quick connector 50 on the other end of the quick connector 50. Each set of male locking structures includes an arc-shaped boss 601 and an elastic damping block 602. The boss 601 and the damping block 602 are sequentially fitted onto the other end of the quick connector 50 along a spiral path and at intervals (the quick connector, boss 601, and damping block 602 are all injection molded from PPS + 40% glass fiber).

[0035] By setting a locking interface 20 and two sets of female locking structures 30 on the outside of the airbag storage cavity, and by using a locking groove 301, a guide groove 302, and an arc-shaped clearance groove 303 to cooperate with the arc-shaped boss 601 and the elastic damping block 602 arranged along the spiral path on the quick connector 50, the airbag can be quickly installed and removed. During installation, the arc-shaped boss 601 and the damping block 602 enter the guide groove 302 through the clearance groove 303. At this time, the quick connector 50 is rotated. The boss 601 and the damping block 602 move along a spiral path in the guide groove 302. The quick connector 50 can be further inserted into the card interface 20 to ensure a tight connection between the quick connector 50 and the airbag storage cavity. As the damping block 602 moves and embeds into the card slot 301, the locking between the quick connector 50 and the airbag storage cavity is completed. During disassembly, simply reverse the quick connector 50 to disengage the damping block 602 from the card slot 301, thus completing the quick disassembly.

[0036] In summary, this structure not only improves the efficiency of airbag installation and removal and facilitates repeated use, but also enhances the anti-loosening ability of the connection parts through the design of the spiral path and damping block 602. In addition, the quick-release structure is simple in design, easy to process and manufacture, effectively reducing production and maintenance costs, and has good economic efficiency and practicality.

[0037] In this embodiment, as Figures 1-9As shown, one end of the quick connector 50 has a groove 80, and a metal pressure ring 70 is embedded inside the groove 80 of the quick connector 50. The opening of the airbag 40 is located between the metal pressure ring 70 and the groove 80 of the quick connector 50. The metal pressure ring 70 is made of aluminum.

[0038] In this embodiment, as Figures 1-9 As shown, the airbag 40 includes a first fabric 401 and a second fabric 402, with one side of the first fabric 401 sewn onto one side of the second fabric 402. (Both the first fabric 401 and the second fabric 402 are woven from nylon material, and the sewing between the first fabric 401 and the second fabric 402 adopts a three-dimensional sewing process, using 3 needles and 5 threads, and the sewing thread uses nylon 66 thread + aramid blended thread).

[0039] In this embodiment, as Figures 1-9 As shown, the seams of the first fabric 401 and the second fabric 402 are coated with a silicone coating, which enhances the airtightness of the airbag 40 and reduces the risk of bursting and frayed edges.

[0040] The specific working process of this utility model is as follows:

[0041] (1) Installation process

[0042] First, align the position of the boss 601 and the clearance groove 303, then let the arc-shaped boss 601 and the damping block 602 enter the guide groove 302 through the clearance groove 303. At this time, turn the quick connector 50 to rotate, and the boss 601 and the damping block 602 move along a spiral path in the guide groove 302. The quick connector 50 can be further inserted into the locking interface 20 to ensure a tight connection between the quick connector 50 and the airbag storage cavity. Then, as the damping block 602 moves and is embedded in the locking groove 301, the locking between the quick connector 50 and the airbag storage cavity is completed.

[0043] (2) Disassembly process

[0044] Simply reverse the quick connector 50 to disengage the damping block 602 from the slot 301, completing the quick disassembly.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
