And a connecting shaft 5041 is arranged on the outer side surface of the vertical plate on two sides of the U-shaped plate frame 504, and the connecting shaft 5041 on two sides of the U-shaped plate frame 504 is rotatably connected with the second folding arm 509.

The upper bearing panel 201 of the cross folding type lifting frame 2 is provided with sliding blocks 202 on two sides, sliding grooves matched with the sliding blocks 202 are formed in two sides inside the garage installation groove 101, the upper bearing panel 201 is connected in the sliding grooves of the garage installation groove 101 in a sliding mode through the sliding blocks 202 on two sides, and the phenomenon that the upper bearing panel 201 is blocked in the moving process is effectively prevented.

The surfaces of the vehicle-carrying platform frame 4, the vehicle-carrying plate 505 and the upper bearing panel 201 are all provided with anti-slip lines, so that the friction force of the vehicle on the vehicle-carrying platform frame 4, the vehicle-carrying plate 505 and the upper bearing panel 201 is improved.

The projection area of the vehicle carrying plate 505 in the vertical direction is smaller than the projection area of the inner periphery of the quadrilateral frame in the vertical direction, so that the vehicle carrying plate 505 can be contracted inside the quadrilateral frame, and the structure of the built-in garage platform 5 is more compact.

Carry the projection area of car rack 4 in vertical side and be less than the projection area of garage mounting groove 101 in vertical side, when alternately foldable promotion frame 2 carries the car shrink in garage mounting groove 101, carry the high sum of car rack 4 and interior concealed garage platform 5 and be less than the interval of vehicle top and ground face 1, make carry the inside that car rack 4 and interior concealed garage platform 5 can remove garage mounting groove 101, make whole mobile garage structure compacter, stability is stronger.

The working principle is as follows: the first motor 301 drives the first screw rod 306 to rotate, so that the first screw rod 306 drives the first nut seat 307 to move in the vertical direction, the vehicle carrying rack 4 is driven by the fixing plate 304 to lift upwards, the upper bearing panel 201 of the cross folding type lifting frame 2 is controlled to lift upwards, the top surface of the upper bearing panel 201 is aligned with the ground surface 1, the vehicle is driven into the upper bearing panel 201, the upper bearing panel 201 is controlled to move into the garage mounting groove 101, parking of a first vehicle is completed, the first motor 301 drives the first screw rod 306 to rotate, the first screw rod 306 drives the first nut seat 307 to move in the vertical direction, the fixing plate 304 drives the vehicle carrying rack 4 to move downwards, the top surface of the vehicle carrying rack 4 is aligned with the ground surface 1, the vehicle is driven into the vehicle carrying rack 4, the second vehicle is completed, the first motor 301 drives the first screw rod 306 to rotate, and the first screw rod 306 drives the first nut seat to move in the vertical direction, the fixing plate 304 drives the vehicle carrying rack 4 to move upwards, the second motor 502 drives the second screw rod 501 to rotate, the second screw rod 501 drives the second nut seat 503 to move rightwards, the second nut seat 503 drives the U-shaped plate frame 504 to drive the second folding arms 509 at the two ends to slide in the first sliding plate frame 507, the second folding arms 509 and the first folding arms 508 are spread, the vehicle carrying board 505 moves downwards to form a quadrilateral frame, the board surface of the vehicle carrying board 505 is in a plane with the floor surface 1, the vehicle is driven into the vehicle carrying board 505, and parking of a third vehicle is completed.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
