The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, an inclined type air bag lifting parking frame includes an under frame 2 contacting with the ground, and an upper frame 1 hinged on the under frame 2, in which the under frame 2 is movable on the ground for a movable type parking frame, and the under frame 2 is fixed on the ground for a fixed type parking frame. An air cushion bag 3 which expands, contracts and ascends due to the inlet and outlet of compressed air is mounted on the bottom frame 2, and the air cushion bag 3 is connected with the upper frame 1 to drive the upper frame 1 to ascend and descend. When the air-lift type bicycle frame is used, the air compressor is started, high-pressure air flow enters the air cushion bag 3, the air cushion bag 3 expands and rises, and the upper frame 1 is lifted up step by step. When the vehicle needs to descend, the air source is closed, air returns, the air cushion bag 3 contracts and descends, and the upper vehicle frame 1 descends so as to take the vehicle conveniently.

In a specific implementation, in order to avoid or reduce the play of the air cushion bag 3 towards the periphery when the air cushion bag 3 rises, the upper frame 1 can be lifted and lowered smoothly under the limitation of the hinge motion with the lower frame during the lifting process as much as possible, as shown in fig. 3, the air cushion bag 3 in the above embodiment comprises an air cushion 301 and an air bag 302 installed in the air cushion 301, and the air bag 302 is inflated by compressed air to lift the whole air cushion bag 3. The structural design mainly utilizes the comprehensive effect of the air bag 302 and the air cushion 301, makes up for the deficiency, the expansion flexibility of the air bag 302 is good but the rigidity is not enough, the rigidity of the air cushion 301 is good but the deformation is slightly poor, in order to realize stable lifting with larger height, the air bag 302 and the air cushion 301 are organically combined to play the effect in a complementary way, the effect of the invention can be played to the full extent, the parameters of the air bag 302 and the air cushion 301, such as the wall thickness, can be selected and dealt with in a compromise way during the specific manufacture, and the structure of the integration of the air bag 302 and the air cushion 301 is not widely applied at present, and is particularly the initiative on a parking frame. To increase the flexibility of air mattress 301, bellows-like air mattress 301 may be used as air mattress 301.

In specific implementation, in order to further reduce or avoid the air cushion bag 3 from moving around during inflation, the air cushion 301 is provided in multiple layers, and one outermost layer is thicker than the other layers, for example, three layers, and the outermost layer is thicker than the two inner layers. Meanwhile, in order to enhance the technical effects, the peripheral side walls of the air cushion 301 are thicker than the walls at the upper and lower ends thereof, so that the up-and-down telescopic stroke of the air cushion 301 is larger as much as possible, and the amount of the air cushion moving towards the periphery is smaller.
