[0027] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0028] This utility model provides an integrated airbag lifting mechanism.

[0029] like Figure 1-6As shown, the integrated airbag lifting mechanism provided in this embodiment of the present invention includes a scissor base 10, a support component 30 and an airbag component 20 disposed on the scissor base 10, and a handle component 40 mounted on the scissor base 10. The scissor base 10 is provided with a lower tray 11 and an upper tray 12. The airbag component 20 is disposed between the lower tray 11 and the upper tray 12. The support component 30 is disposed on the upper tray 12 and is fixed by the upper side of the scissor base 10.

[0030] In this embodiment, when the airbag component 20 is inflated and lifted, the support component 30 can be lifted by the upper tray 12 and lifted by the support component 30, thereby replacing the hydraulic cylinder and making it lighter than a conventional lift.

[0031] The scissor base 10 includes an outer scissor arm 13, an inner scissor arm 14, and a scissor hinge 15. The middle parts of the outer scissor arm 13 and the inner scissor arm 14 are rotatably connected to the scissor hinge 15. A rotating hinge 16 is provided on the outer scissor arm 13 and the inner scissor arm 14. Both ends of the upper tray 12 and the lower tray 11 are rotatably connected to the rotating hinge 16.

[0032] The airbag component 20 installed between the upper tray 12 and the lower tray 11 on both sides serves as the lifting power source. Before the airbag component 20 inflates, the lever arms of the outer scissor arm 13 and the inner scissor arm 14 are at the same level. As the airbag inflates, it expands and opens the upper and lower trays 11. The upper and lower trays 11 expand the scissor forks, which then lifts the support component 30 to one side of the car, thus lifting it up. After the safety bracket is placed, the mechanic can then repair the chassis or replace the tires. At this time, the angle between the lever arms of the outer scissor arm 13 and the inner scissor arm 14 will gradually increase, thereby lifting the top support component 30. The load-bearing wheels 17 on both sides roll inward on the ground to avoid dry friction from the scissor movement.

[0033] In non-lifting state, such as Figure 2 As shown, the end of the outer scissor arm 13 is provided with a load-bearing wheel 17 and a universal wheel 18. The universal wheel 18 and the load-bearing wheel 17 are grounded, which facilitates the movement of the lifting mechanism and the alignment of the bottom of the car.

[0034] Please refer to Figure 3 and Figure 4The support assembly 30 includes a main crossbeam 31 and an extension beam 32 fitted inside the main crossbeam 31. A support plate 33 is mounted on the extension beam 32. An elastic pin 37 is mounted on the main crossbeam 31. The extension beam 32 has limit holes aligned with the elastic pin 37, into which the elastic pin 37 can be inserted. The extension beams 32 on both sides are inserted into the main crossbeam 31. The extension length of the extension beams 32 can be adjusted according to the vehicle width to adapt to different vehicles. During adjustment, the elastic pin automatically engages with the limit holes of the extension beams 32 to prevent the user from exceeding the safe operating width. The bottom of the support plate 33 has a support shaft 36 with several holes, which is inserted into a bushing on the extension beam 32. Different holes are used to adjust the operating height, and the pin 37 is then used for quick positioning.

[0035] The bottom of the main crossbeam 31 is provided with a fixed sleeve 34 and a sliding groove seat 35, which are respectively connected to the top of the outer shear arm 13 and the inner shear arm 14. The fixed sleeve 34 has a fixing hole 341, and the sliding groove seat 35 has a sliding groove 351. The outer shear arm 13 and the inner shear arm 14 are provided with two supporting hinges 19, which are respectively located in the fixing hole 341 and the sliding groove 351.

[0036] The fixed sleeve 34 and the sliding groove seat 35 are respectively installed on the top of the outer scissor arm 13 and the inner scissor arm 14, with one side having a hole and shaft connection and the other side having a long groove and shaft connection. This connection structure ensures that the outer scissor arm 13 and the inner scissor arm 14 will not be jammed when the angle is opened, and the support assembly 30 can always be kept in a horizontal state to prevent the vehicle from tipping over to the left or right.

[0037] Please refer to Figure 5-6 The handle component 40 includes a front connecting rod 41, a rear connecting rod 42, and a grip handle 43. The front connecting rod 41 and the rear connecting rod 42 are rotatably connected. The end of the front connecting rod 41 away from the rear connecting rod 42 is connected to the base component. The grip handle 43 is located at the end of the rear connecting rod 42 away from the front connecting rod 41. An air tube 44 connected to the airbag component 20 is provided on the rear connecting rod 42. The air tube 44 is connected to a manual valve 45. A quick-connect connector 46 is installed on the manual valve 45.

[0038] The air source enters the manual valve 45 through the quick-connect connector 46. The gas enters the two airbag components 20 through the manual valve 45, the air pipe 44, and the T-shaped tube at the end of the air pipe 44. The front connecting rod 41 and the rear connecting rod 42 are connected by screws. After the quick-connect pin 37 is pulled out, different angles can be switched, which is beneficial for users to use in different environments and is also easy to store.

[0039] Please refer to Figure 2When the product is lowered to its lowest position, its height does not exceed 150mm, which is suitable for use in cars with low chassis. Furthermore, it occupies little space when folded, making it easy to store.

[0040] In other embodiments, the scissor base 10 can be plate-shaped or tubular. The support beam of the support assembly 30 can be a single beam or a combination of multiple beams. The support plate 33 can be square or circular. The handle 43 can be foldable, telescopic, or non-telescopic and foldable; control can be a manual valve 45, a solenoid valve, a ball valve, etc. The casters 18 can be one or two sets. The airbags can be two, one, or multiple in a manner that provides power.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
