[0031] Embodiment 1

[0032] Refer to Figures 1-5 , a safety anti-falling three-dimensional parking garage, including a car-carrying board 1 and a three-dimensional lifting component 2, which are respectively used for carrying a vehicle and lifting the car-carrying board 1. The car-carrying board 1 is horizontally installed in the three-dimensional lifting component 2. Limiting blocks 13 are symmetrically arranged on both sides of the top wall of the car-carrying board 1 corresponding to the wheelbase of the car, and are used to limit the wheels on the inner sides of the two wheels to prevent the vehicle from slipping to both sides. A protective cover 14 is arranged on the car-carrying board 1 to protect the internal structure of the car-carrying board 1 and also prevent damage to the vehicle chassis, ensuring the use effect of the car-carrying board 1. A plurality of limiting plates 3 corresponding to the vehicle wheels are slidably arranged on both sides of the protective cover 14 and are used to limit the front wheels or rear wheels when the vehicle drives in.

[0033] A strip-shaped groove is formed in the middle of the car-carrying plate 1. A main shaft 6 is rotatably installed in the strip-shaped groove. The main shaft 6 is connected with a driving mechanism. The main shaft 6 is driven to rotate by the driving mechanism. A plurality of driving bevel gears 5 are fixedly sleeved on the main shaft 6. Driven bevel gears 4 are meshed on both sides of the driving bevel gear 5. On the opposite sides of the driven bevel gears 4, stud bolts 311 are coaxially and fixedly connected. On the top wall of the car-carrying plate 1, a plurality of sliding grooves 32 are formed corresponding to the stud bolts 311. Threaded sliders 31 are slidably arranged in the sliding grooves 32. The threaded sliders 31 are respectively in threaded rotational connection with the corresponding stud bolts 311. And the threaded sliders 31 are respectively fixedly installed on the bottom walls of the corresponding limiting plates 3. By driving the driven bevel gears 4 on both sides to rotate through the driving bevel gear 5, the stud bolts 311 are driven to rotate, and then the threaded sliders 31 are driven to slide, so that the limiting plates 3 are driven to press against the tire side walls, thereby fixing the wheels and ensuring the positioning effect of the vehicle.

[0034] Through grooves 91 are formed in the two sides inside the limiting plate 3 in a penetrating manner. Sliding blocks 9 are slidably installed in the through grooves 91. On the opposite sides of the sliding blocks 9, limiting claws 11 extend outwards. On the adjacent sides of the sliding blocks 9, fixing blocks 10 are fixedly connected. On one side of each fixing block 10, the telescopic ends of electric struts 12 are fixedly connected. The electric struts 12 are respectively fixedly installed on the inner side walls of the corresponding limiting plates 3. After the vehicle stops at the corresponding position, the limiting plates 3 slide outwards to press against the inner sides of the wheels. Then the electric struts 12 are started to drive the limiting claws 11 to move, so that the limiting claws 11 press against the wheels at the rear sides of the tires, thereby limiting the wheels and ensuring the positioning effect of the vehicle.

[0035] When the three-dimensional parking garage is in use, the vehicle to be parked is driven onto the car-carrying plate 1 until the front wheels contact the limiting blocks 13 to block the vehicle. The vehicle is stopped stably and the handbrake is pulled up. The servo motor 7 is started to drive the main shaft 6 and the driving bevel gear 5 to rotate, and then the driven bevel gears 4 and the stud bolts 311 on both sides are driven to rotate. In cooperation with the threaded sliders 31, the limiting plates 3 are driven to slide outwards until the limiting plates 3 contact and press against the inner walls of the wheels, thereby fixing the vehicle wheels and preventing the vehicle from sliding in the lateral directions, thus fixing the vehicle. After the limiting plates 3 are fixed, the electric struts 12 are started to drive the sliding blocks 9 and the limiting claws 11 to slide until the limiting claws 11 contact the wheel surfaces, further limiting the wheels in the front-back direction, preventing the vehicle from sliding in the neutral gear state due to improper operation during parking, fixing the position of the vehicle, and at the same time cooperating with the limiting blocks 13 to clamp and fix the front wheels of the vehicle, further ensuring the fixing effect of the wheels and preventing the vehicle from falling during lifting, thus ensuring the safety of the use of the three-dimensional parking garage.

[0036] When the vehicle needs to drive out, first start the electric struts 12 to drive the limiting claws 11 to disengage from the wheel surfaces, and then start the servo motor 7 to drive the limiting plates 3 to retract inwards, driving the limiting claws 11 to disengage from the moving route of the wheels, facilitating the driving out of the vehicle and improving the usability of the three-dimensional parking garage.

[0037] In this embodiment, as Figure 1 and 2 shown, the three-dimensional lifting assembly 2 includes vertical guide rails 21 symmetrically and vertically arranged on both sides of the car carrier plate 1. At the lower ends of the vertical guide rails 21, bottom plates 22 are horizontally provided. Sliding seats 23 are slidably installed in the vertical guide rails 21. Both ends of a chain belt 26 are respectively connected to the upper and lower sides of the sliding seat 23. A plurality of rotating wheels 27 are rotatably provided in the chain belt 26. One of the rotating wheels 27 is fixedly sleeved on the output end of the driving motor 28. The driving motor 28 is horizontally and fixedly installed on the side wall of the vertical guide rail 21 through a bracket. By driving the rotating wheel 27 to rotate by the driving motor 28 and cooperating with the chain belt 26 to drive the sliding seat 23 to move up and down, the car carrier plate 1 is driven to lift, ensuring the use effect of the three-dimensional parking space.

[0038] In this embodiment, as Figure 1 and 2 shown, two connecting plates 24 and the two sides of the car carrier plate 1 are respectively fixedly connected with pull rods 25, improving the stability of the car carrier plate 1 during use and ensuring the load-bearing capacity of the car carrier plate 1.

[0039] In this embodiment, as Figure 2 and 3 shown, the driving mechanism includes a driven gear 61 fixedly sleeved on the main shaft 6. The driven gear 61 meshes with a driving gear 62. The driving gear 62 is fixedly sleeved on the output end of the servo motor 7. The servo motor 7 is installed on the car carrier plate 1 through a bracket. By the servo motor 7 cooperating with the driven gear 61 and the driving gear 62 to drive the main shaft 6 to rotate, it is convenient to control the limiting plate 3 to slide to both sides.

[0040] In this embodiment, as Figure 2 and 3 shown, an installation opening corresponding to the servo motor 7 is provided on the car carrier plate 1. The servo motor 7 is fixedly arranged in the installation opening through a bracket, reducing the installation space of the servo motor 7 and the required thickness of the car carrier plate 1, ensuring the space utilization rate of the three-dimensional parking garage.

[0041] In this embodiment, as Figures 1-5 shown, arc-shaped limiting grooves corresponding to the wheels are provided on a plurality of the limiting claws 11, improving the fitting effect with the wheels and ensuring the limiting ability for the wheels.
