Description

Technical Field

[0001] This utility model relates to the field of automotive lift airbag technology, specifically to an automotive lift airbag. Background Technology

[0002] In today's rapidly developing automotive industry, automobiles have evolved from simple means of transportation into mobile spaces that integrate high technology and comfortable experiences. Consumers' expectations for vehicle performance are constantly rising; in addition to basic elements such as power and safety, they are demanding higher levels of driving comfort, off-road capability, and overall vehicle performance balance. This trend has prompted automakers to continuously explore and upgrade various subsystems of automobiles. Among these, the suspension system, as a key component directly affecting vehicle ride quality, has become a focus of technological innovation, thus necessitating the design of an airbag system for automobiles.

[0003] Existing airbags are single-layer automotive airbags, which have significant limitations in protection during emergencies or extreme road conditions. For example, when driving over potholes at high speeds or during a collision, a single-layer airbag may not be able to adequately absorb and disperse the impact force, leading to significant vibrations to the vehicle body and increasing the risk of injury to occupants. Single-layer airbags are also prone to wear and aging, further reducing their protective performance and making it difficult to consistently provide reliable protection for the vehicle and passengers. Therefore, installing double-layer airbags inside a single-layer airbag to form a multi-layer protective structure can significantly improve the overall protective capability of the airbag. The multi-layered cushioning mechanism minimizes the vibrations transmitted to the vehicle body, providing more reliable safety protection for occupants and effectively reducing the risk of injury to the vehicle and passengers in various unexpected situations. The multiple airbags work together to enhance cushioning and ensure vehicle stability. This adaptive cushioning performance can better... To meet users' needs in various driving scenarios and significantly improve the driving experience, existing airbags typically rely on their own rubber material and simple structure to provide support and cushioning, offering relatively limited performance. This makes them difficult to adapt to different road conditions. Airbags may lose their normal support function due to insufficient pressure, leading to vehicle sagging, loss of balance, and affecting vehicle handling and driving safety. This not only reduces ride comfort but may also damage vehicle components and shorten the vehicle's lifespan in the long run. Therefore, spiral reinforcing ribs are installed inside the airbag to improve its support performance. The spiral structure can evenly distribute pressure, effectively transmitting vertical and lateral forces from the road surface to the entire airbag, preventing deformation caused by excessive local pressure. Under heavy loads or complex road conditions, the spiral reinforcing ribs act like a steel frame in a building, providing stable support for the airbag, ensuring vehicle stability, and improving vehicle handling safety. Utility Model Content

[0004] The technical problem this utility model aims to solve is as follows: It provides a highly practical automotive airbag with a simple structure and easy operation, addressing the shortcomings of existing single-layer airbags mentioned in the background. These airbags are insufficient in providing adequate protection during sudden events or extreme road conditions. For example, when driving over potholes at high speeds or during collisions, a single-layer airbag may not be able to fully absorb and disperse the impact, causing significant vibration to the vehicle body and increasing the risk of injury to occupants. Furthermore, single-layer airbags are prone to wear and aging, further reducing their protective performance and making it difficult to consistently provide reliable protection for the vehicle and passengers. Therefore, by installing double-layer airbags inside a single-layer airbag to form a multi-layer protective structure, the overall protective capability of the airbag is significantly improved. The multi-layer buffering mechanism minimizes the vibration transmitted to the vehicle body, providing more reliable safety protection for occupants and effectively reducing the risk of injury to the vehicle and passengers in various unexpected situations. The multiple airbags work together effectively. To enhance cushioning and ensure vehicle stability, this adaptive cushioning performance better meets the needs of users in various driving scenarios, significantly improving the driving experience. Existing airbags typically rely on their own rubber material and simple structure for support and cushioning, offering relatively limited performance and difficulty adapting to different road conditions. Airbags may lose their normal support function due to insufficient pressure, leading to vehicle sag, imbalance, and impacting handling and driving safety. This not only reduces ride comfort but can also damage vehicle components and shorten the vehicle's lifespan in the long run. Therefore, a spiral reinforcing rib is installed inside the airbag to improve its support performance. The spiral structure evenly distributes pressure, effectively transmitting vertical and lateral forces from the road surface to the entire airbag, preventing deformation caused by excessive local pressure. Under heavy loads or complex road conditions, the spiral reinforcing rib acts like a steel frame in a building, providing stable support for the airbag, ensuring vehicle stability and improving handling safety.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A car lift airbag includes a lift frame, a central shaft mounted in the middle of the lift frame, a retaining mechanism sleeved on the outer side of the central shaft's middle end, a base plate mounted on the bottom of the retaining mechanism, and a reinforcing mechanism fixedly connected to the bottom surface of the base plate. The retaining mechanism includes an inner double-ball airbag sleeved on the outer side of the central shaft's middle end, an outer protective airbag sleeved on the outer side of the inner double-ball airbag, and the upper and lower surfaces of the inner double-ball airbag being installed inside the upper and lower surfaces of the outer protective airbag. The reinforcing mechanism includes a base column fixedly connected to the bottom surface of the base plate, a cavity formed inside the base column, and a spiral reinforcing rib fixedly connected to the bottom surface of the cavity. The inner surface of the spiral reinforcing rib is sleeved on the outer side of the central shaft.

[0007] As a further embodiment of this utility model: a stop post is installed on the top surface of the spiral reinforcing rib, and a top plate is fixedly connected to the top surface of the stop post. The top plate serves to block and support at the top.

[0008] As a further embodiment of this utility model: an air vent is provided on the left side of the top surface of the top plate, and an air vent valve is fixedly connected to the outside of the air vent. The air vent valve is used to control the released gas to adapt to the external environment.

[0009] As a further embodiment of this utility model: the top of the air valve is provided with an air outlet, and a dustproof net is installed inside the air outlet. The dustproof net prevents dust from entering the air outlet and clogging it.

[0010] As a further embodiment of this utility model: an air inlet is provided on the left side of the top surface of the base plate, and an air inlet valve is fixedly connected to the outside of the air inlet. A connecting hose passes through the end of the air inlet valve. The air inlet valve facilitates the control of air intake inside the airbag.

[0011] As a further embodiment of this utility model: the end of the connecting hose is provided with a connector, the connector is externally threaded with a sealing nut, and a heat-shrink sealing ring is fitted around the sealing nut. The sealing nut serves to prevent loosening and air leakage by reinstalling it on the outside of the connector.

[0012] As a further embodiment of this utility model: connecting pipes (15) are installed at both the upper and lower ends of the central shaft, and a mounting bracket is installed not far from the top surface of the lower connecting pipe. A rotating shaft is rotatably connected to the middle of the mounting bracket, and a connecting plate is fixedly connected to the top of the rotating shaft. The interior of the connecting plate is fixedly connected to the lower end of the central shaft. The mounting bracket facilitates the installation of the device on the interior parts of the vehicle.

[0013] The beneficial effects of this utility model are:

[0014] 1. Through the design of the anti-corrosion mechanism, when the device is in use, it inflates the inner double-ball airbag and outer protective airbag by opening the intake valve, or releases a small amount of air by opening the exhaust valve to adapt to the external road conditions, increasing the vehicle's stability and comfort. Since traditional single-layer airbags are prone to aging and becoming unusable, an inner double-ball airbag is installed inside the single-layer outer protective airbag to prevent this. The simultaneous action of the two airbags not only enhances the cushioning capacity but also protects the inner airbag. Even after the outer protective airbag is damaged or aged, the inner airbag can continue to be used for a period of time, preventing sudden airbag failure that could affect vehicle operation and occupant safety. This provides double-layer protection and enhanced cushioning, avoiding the problem that a single-layer airbag might not be able to fully absorb and disperse impact force, thus increasing the risk of injury to occupants. It provides more reliable safety protection for vehicle occupants, effectively reducing the risk of injury, enhancing cushioning, ensuring vehicle stability, and improving the driving experience.

[0015] 2. By strengthening the mechanism, the gas levels inside the inner double-ball airbag and outer protective airbag are adjusted to buffer external forces during use. To prevent damage to the double-layer airbags from large impacts, a base column is installed on the top surface of the base plate. This base column also supports the outer airbag in the middle. Furthermore, a spiral reinforcing rib is installed inside the base column. This spiral reinforcing rib disperses external pressure throughout the double-layer airbag, protecting it from damage. Simultaneously, the spiral reinforcing rib also provides support in the middle. Even if the outer double-layer airbag is damaged, the internal spiral reinforcing rib can provide temporary support, protecting the vehicle and its occupants. This strengthens support and buffers the airbags, preventing vehicle sagging and imbalance, which could affect vehicle handling and driving safety. Therefore, it improves the airbag's support performance, provides stable support for the airbags, ensures vehicle stability, and enhances vehicle handling safety. Attached Figure Description

[0025] The reinforcing mechanism 5 includes a base column 501 fixedly connected to the bottom surface of the base plate 4. The base column 501 has a cavity inside, and a spiral reinforcing rib 502 is fixedly connected to the bottom surface inside the cavity. The spiral reinforcing rib 502 is sleeved on the outside of the central shaft 2.

[0026] like Figure 3 As shown, a stop post 6 is installed on the top surface of the spiral reinforcing rib 502, and a top plate 7 is fixedly connected to the top surface of the stop post 6. The top plate 7 serves to block and support at the top.

[0027] like Figure 2 As shown, an air vent is provided on the left side of the top surface of the top plate 7. An air vent valve 8 is fixedly connected to the outside of the air vent. The air vent valve 8 is used to control the released gas to adapt to the external environment.

[0028] like Figure 4 As shown, the top of the air outlet valve 8 is provided with an air outlet, and a dustproof net 9 is installed inside the air outlet. The dustproof net 9 is designed to prevent dust from entering the air outlet and clogging it.

[0029] like Figure 4 As shown, an air inlet is provided on the left side of the top surface of the base plate 4. An air inlet valve 10 is fixedly connected to the outside of the air inlet. A connecting hose 11 passes through the end of the air inlet valve 10. The air inlet valve 10 facilitates the control of air intake inside the airbag.

[0030] like Figure 4 As shown, a connector 12 is passed through the end of the connecting hose 11. A sealing nut 13 is threaded onto the outside of the connector 12. A heat-shrinkable sealing ring 14 is fitted onto the outside of the sealing nut 13.

[0032] The above parameters and models can be selected according to actual needs.

[0033] The working principle of this utility model is as follows: When the device is in use, depending on the external road conditions, air is inflated into the inner double-ball airbag 301 and the outer protective airbag 302 by opening the air intake valve 10, or a small amount of air is released by opening the air outlet valve 8 to adapt to the external road conditions, thereby increasing the stability and comfort of the vehicle.

At the same time, the spiral reinforcing rib 502 also provides support in the middle. Even if the outer double-layer airbag is damaged or destroyed, the internal spiral reinforcing rib 502 can provide temporary support to protect the safety of the vehicle and its occupants.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
