Description

Technical Field

[0001] This utility model relates to the field of airbag device technology, specifically to an Omega spring-loaded airbag device. Background Technology

[0002] A patent document with publication number CN106122339B discloses a sealing device for connecting an air spring airbag to a cover plate, belonging to the field of sealing devices. It includes an upper cover plate, an outer buckle ring, an inner buckle ring, a central ring, an annular clamp, and an airbag. The central ring mainly serves a supporting function, with its outer surface being a wedge-shaped surface with a wedge slope of α. The annular clamp serves a clamping function, with its inner surface also being a wedge-shaped surface with a wedge slope of β, where β = α + k. The outer buckle rings, arranged circumferentially, serve a connecting function. Before installation, the outer buckle rings are open; after installation, they deform and tighten under the constraint of the annular clamp, tightly fitting against the inner surfaces of the airbag and the clamp. This structure connects the airbag and the cover plate, creating three contact surfaces between the cover plate and the airbag, effectively improving problems such as air leakage and detachment caused by insecure sealing between the airbag and the cover plate.

[0003] Existing technologies focus more on the connection, sealing, and stability of the airbag and cover plate in structural design. In terms of improving cushioning performance, some devices lack a dedicated double-layer cushioning structure. When facing some complex or strong impact scenarios, there is still room for improvement in their cushioning effect, which may not be able to fully meet the needs of airbag cushioning performance.

[0004] Therefore, this utility model proposes an Omega spring-loaded airbag device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an Omega spring-loaded airbag device, comprising a mounting base, an airbag body, and a fixing screw, wherein the mounting base is fixedly mounted on the airbag body, and the fixing screw is threadedly connected between the mounting base and the airbag body;

[0007] The airbag body is provided with an elastic component, a buffer component, and a double-layer component. The elastic component is located inside the airbag body, the buffer component is located on the inner side of the airbag body, and the double-layer component is located on the side of the airbag body.

[0008] Preferably, the top end of the telescopic rod in the elastic component is provided with a fixing plate, and the bottom end of the telescopic rod is fixedly installed at the bottom of the airbag body.

[0009] Preferably, a first spring is sleeved on the telescopic rod of the elastic component, and one end of the first spring is fixedly disposed at the bottom of the fixed plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up elastic components and utilizing the elastic action of the telescopic rod in conjunction with the first spring, the overall elastic support capacity of the airbag body is enhanced; the buffer layer in the buffer component is evenly distributed, which can further improve the buffering effect inside the airbag body; the double-layer component uses the inner airbag wall and the outer airbag wall to form a buffer cavity, combined with the second spring in the cavity, to construct a special double-layer buffer structure, which can effectively disperse and absorb external impacts.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0020] Example 1: Please refer to Figures 1 to 2 An Omega spring-loaded airbag device includes a mounting base 1, an airbag body 2, and a fixing screw 3. The mounting base 1 is fixedly mounted on the airbag body 2, and the fixing screw 3 is threadedly connected to the mounting base 1 and the airbag body 2. The airbag body 2 is provided with an elastic component 4, a buffer component 5, and a double-layer component 6. The elastic component 4 is disposed inside the airbag body 2, the buffer component 5 is disposed inside the airbag body 2, and the double-layer component 6 is disposed on the side of the airbag body 2.

[0021] The top end of the telescopic rod 401 in the elastic component 4 is provided with a fixing plate 402, and the bottom end of the telescopic rod 401 is fixedly installed at the bottom of the airbag body 2.

[0022] In use, the mounting base 1 is securely connected to the airbag body 2 by the fixing screws 3, ensuring that the overall structure is installed in place. When the airbag body 2 is subjected to external force, the telescopic rod 401 in the elastic component 4 will move with the external force, and the fixing plate 402 will move accordingly. Its connection with the bottom of the airbag body 2 ensures the stability of the movement, initially alleviating the impact of external force on the airbag body 2, and laying the foundation for further cushioning.

[0023] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The first spring 403 is sleeved on the telescopic rod 401 in the elastic component 4, and one end of the first spring 403 is fixedly set at the bottom of the fixed plate 402.

[0024] The telescopic rod 401 in the elastic component 4 is fixed by the fixing screw 3, and the buffer layer 501 in the buffer component 5 is evenly arranged inside the airbag body 2.

[0025] In use, the telescopic rod 401 remains stable under the fixation of the fixing screw 3. When subjected to external force, the telescopic rod 401 extends and retracts, causing the fixing plate 402 to move. The first spring 403 deforms due to the movement of the fixing plate 402, and absorbs part of the impact force with its own elasticity, thereby enhancing the buffering effect. At the same time, the buffer layer 501 in the buffer assembly 5 is evenly distributed inside the airbag body 2. Its material properties can effectively absorb energy and further absorb the force transmitted to the airbag body 2, reducing the impact.

[0026] Example 3: Based on Example 2, please refer to... Figures 3 to 4 In the double-layer component 6, the inner airbag wall 601 is located inside the airbag body 2, and a buffer cavity 603 is provided between the inner airbag wall 601 and the outer airbag wall 602. The outer airbag wall 602 is located on the airbag body 2.

[0027] The buffer cavity 603 in the double-layer component 6 is uniformly provided with a second spring 604. The end 605 of the second spring 604 is fixedly disposed on the outside of the inner airbag wall 601, and the second end 606 of the second spring 604 is fixed on the inside of the outer airbag wall 602.

[0028] When in use, when an external force is applied to the airbag body 2, the inner airbag wall 601 is subjected to force first. The force is transmitted through the inner airbag wall 601 to the second spring 604 in the buffer cavity 603. The second spring 604 is fixed by the end 605 and the second end 606, and deforms to absorb the force. The remaining force is transmitted to the outer airbag wall 602. With the help of the elastic component 4 and the buffer component 5, the multi-layer buffer structure works together to disperse the force from different dimensions, greatly reducing the impact of external force on the airbag body 2.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
