[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] Reference Figure 1-6 As shown, a lifting parking rack with an expansion function provided by the first embodiment of the present invention includes a vehicle loading plate, a first support frame 3, a second support frame 11 and multiple lifting devices, wherein the first support frame 3 and the second support frame 11 are provided with two vertical grooves on the left and right sides, and the lifting device includes a screw rod 1, an adjusting block 2 and a driving motor, the screw rod 1 is arranged in the vertical grooves of the first support frame 3 and the second support frame 11, and a gear box 4 is arranged at the bottom of the screw rod 1, and the gear box 4 is driven by the driving motor, one end of the adjusting block 2 is threadedly connected to the screw rod 1, and the other end is fixedly connected to the vehicle loading plate, when the driving motor drives the internal gear of the gear box 4 to rotate, the gear drives the screw rod 1 to rotate, and the screw rod 1 cooperates with the adjusting block 2 to lift the vehicle loading plate.

[0027] The vehicle loading plate includes a U-shaped support 5 and a load-bearing plate 6. The load-bearing plate 6 is movably connected to the U-shaped support 5. The rear end of the U-shaped support 5 is provided with a transverse through hole, and the upper part of the load-bearing plate 6 can pass through the transverse through hole. The front end of the load-bearing plate is hingedly connected to the main body of the load-bearing plate 6. A driving gear 17 is provided at the hinge between the front end of the load-bearing plate and the main body of the load-bearing plate 6. The driving gear 17 drives the front end of the load-bearing plate to flip. The front end of the load-bearing plate flips upward with the hinge point as the center of the circle, so that the front end of the load-bearing plate and the main body of the load-bearing plate are in a vertical state. At this time, the front end of the load-bearing plate can block the direction of the vehicle entering the parking space to prevent the vehicle from accidentally sliding down.

[0028] The rear end of the lower part of the load-bearing plate 6 is distributed in a stepped manner, and the hydraulic system is arranged at the stepped position of the load-bearing plate 6. The U-shaped support 5 is connected to the load-bearing plate 6 through the hydraulic system. The load-bearing plate 6 can be pushed by the hydraulic system in a direction away from the U-shaped support 5 to stretch the load-bearing area of ​​the vehicle load-bearing plate.

[0029] The hydraulic system includes two groups of hydraulic telescopic rods, which are composed of a front rod 9 and a rear rod 10 that are socketed with each other. The socketed ends of the front rod 9 and the rear rod 10 are hollow, and a hydraulic cavity is formed in the middle of the socketed part of the front rod 9 and the rear rod 10. Hydraulic oil is injected into the hydraulic cavity, and the hydraulic cavity is connected to an external electric hydraulic pump through a conduit. The front rod 9 is fixedly connected to the bearing plate 6, and the rear rod 10 is fixedly connected to the U-shaped support 5. When hydraulic oil is injected into the hydraulic cavity, the front rod 9 is pushed out, driving the bearing plate 6 to move in a direction away from the U-shaped support 5.

[0030] The U-shaped support member 5 is provided with slide grooves 13 on both sides, and the two sides of the carrier plate 6 are inserted into the slide grooves 13 and can slide along the direction of the slide grooves 13. A U-shaped ball plate 16 matching the shape of the slide groove 13 is provided between the parts of the two sides of the carrier plate 6 inserted into the slide grooves 13 and the slide grooves 13. The U-shaped ball plate 16 is provided with slot holes at both ends, and the balls 7 are installed in the slot holes. The ball 7 in the upper slot hole is exposed below the slot hole and the part of the carrier plate inserted into the slide groove, and the ball 7 in the lower slot hole is exposed above the slot hole and the part of the carrier plate inserted into the slide groove. Nuts are installed on the side of the U-shaped ball plate 16. The U-shaped ball plate 16 is fixedly installed in the slide groove 13 by the nuts, which reduces the friction force when the carrier plate 6 slides, and the carrier plate 6 is more easily pushed by the hydraulic system, while limiting the range of the carrier plate 6 being pushed.

[0031] The adjustment blocks 2 are symmetrically arranged on both sides of the U-shaped support 5. Two adjustment blocks are distributed on one side of the U-shaped support. One adjustment block 2 is located close to the rear end of the U-shaped support 5, and the other is located close to the front end of the U-shaped support 5, thereby forming a balanced lifting structure to prevent the vehicle loading plate from shaking during the lifting process.

[0032] The bottom of the first support frame 3 and the second support frame 11 is provided with a base 15, and the base 15 is provided with a support shell 18 for accommodating the support frame. Threaded holes are provided on both sides of the support shell 18, and the support frame is provided with openings corresponding to the positions of the threaded holes. Nuts pass through the threaded holes and the support frame openings to fix the support shell 18 to the support frame. The support shell is provided with a slot for the adjustment block 2 to slide. A longitudinal stiffening plate 14 is installed on the base 15, and one edge of the stiffening plate 14 is fixedly connected to the support shell 18, and the other edge is fixedly connected to the base 15. The base 15 is fixed to the ground by tightening the fixing nuts 12 at both ends. This structure makes the support frame and the base detachable. During installation, the support frame installation position can be fixed by first setting a lighter and easier to adjust base 15. The support shell 18 and the stiffening plate 14 can further reinforce the support frame at the same time, so that the entire lifting parking frame has stability while being easy to disassemble and install.

[0033] After adopting the above technical solution, when the vehicle needs to park in the parking space, the vehicle loading plate is at the lower end of the support frame, the electric hydraulic pump is started, and hydraulic oil is injected into the hydraulic cavity in the parking rack hydraulic system, and the front rod 9 is pushed out, driving the load-bearing plate 6 away from the U-shaped support 5. The part of the load-bearing plate 6 that passes through the U-shaped support 5 fills the space where the upper load-bearing plate 6 is pushed out, so that the load-bearing area of ​​the vehicle loading plate is in an extended state. In this state, it is convenient for the owner to adjust the vehicle body and park the vehicle on the vehicle loading plate more easily. After parking the vehicle, the control drive motor starts to work, and the gear box 4 at the bottom of the control screw rod rotates, so that the screw rod 1 rotates. At this time, the adjustment blocks 2 on both sides lift the vehicle loading plate at a uniform speed, thereby freeing up the position at the bottom of the parking rack for parking other vehicles. After the vehicle loading plate rises, the electric hydraulic pump extracts the hydraulic oil in the hydraulic cavity, and the front rod 9 shrinks toward the rear rod 10, driving the load-bearing plate 6 close to the U-shaped support 5, and the load-bearing area of ​​the vehicle loading plate shrinks to avoid occupying more space. When installing the parking rack, the base 15 can be installed at the designed position first, and then the support frame can be installed on the base 15. Compared with directly moving the support frame, it is more convenient to adjust the lighter base 15. The support shell 18 and the stiffening plate 14 provided on the base 15 also help to improve the stability of the overall device after the support frame is installed. In this structure, lifting the vehicle loading plate only requires two sets of screw lifting structures in close positions on the left and right. Compared with the general lifting parking rack that uses a sling to lift the four corners of the vehicle loading plate, the space occupied by the lifting structure is reduced, and there can be more adjustment space when parking, allowing the owner to park in the parking space more easily. In this structure, screw lifting structures can be installed on both sides of a support frame, which reduces the space occupied by the parking rack as a whole, so as to improve the space utilization rate of the parking garage. The support frame can be easily disassembled and installed through the base, and is easy to maintain.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
