[0022] S1, driving a vehicle above the pressure drive mechanism, the upper end of the pressure drive mechanism is under pressure, and the water in the water storage chamber is pressed into the first water tank through the first pipe. At this time, the total weight of the water in the first water tank and the first water tank is greater than the pressure drive mechanism, the movable bracket and the first vehicle.

When a vehicle is parked at the vehicle placement position, the gravity of the vehicle can drive the pressure drive mechanism and press the water in the water storage chamber into the first water tank. At this time, the sum of the weight of the first water tank and the water in the first water tank is greater than the sum of the weight of the movable bracket, the pressure drive mechanism and the vehicle. Therefore, the first water tank descends, and the movable bracket drives the vehicle to rise. Further, a placement space capable of accommodating a second vehicle is formed under the movable bracket. The micro-stereoscopic parking garage proposed by the present invention has a compact structure, a clever design, is easy to disassemble and assemble, can be widely used in indoor or outdoor parking areas, greatly saves installation costs, and improves space utilization.

It does not require the drive of an electric motor or internal combustion engine. The design is ingenious, energy-saving and environmentally friendly.

[0026] According to the solution of the present invention, two groups of pressure drive mechanisms are provided corresponding to the wheels on both sides of the vehicle, and each group of pressure drive mechanisms includes a gravity pressure plate, a hydraulic plate and a guide column. The gravity pressure plate is connected to the hydraulic plate through the guide column. The gravity pressure plate is provided at the upper end of the movable bracket.

Through the design of this structure, when the vehicle leaves the upper end of the movable bracket, the return spring can push the hydraulic plate upward to restore it to the initial state, so that the water storage chamber can receive external water source or internal water source.

[0028] According to the solution of the present invention, the micro-stereoscopic parking garage also includes a gravity safety locking mechanism, which can lock the movable bracket when no vehicle is parked on the gravity pressure plate, and unlock the movable bracket when the vehicle is parked on the gravity pressure plate, thereby improving the safety and stability of the solution of the present invention.

[0029] According to the solution of the present invention, inclined plates are rotatably provided at both ends of the gravity pressure plate. In the initial state, the end of the inclined plate abuts the ground, and the vehicle enters above the gravity pressure plate through the inclined plate. In the working state, the gravity pressure plate descends, and the inclined plate is limited by the movable bracket, and one end of the inclined plate tilts upward to form a safety baffle to prevent the vehicle from escaping from the gravity pressure plate. Through the design of this structure, the device of the present invention can be placed directly on the ground, and the vehicle can enter and exit the vehicle placement position at the upper end of the movable bracket through the inclined plate, and after the vehicle is parked at the vehicle placement position at the upper end of the movable bracket, the inclined plate can be rotated to form a safety baffle to prevent the vehicle from escaping.

In order to ensure that the sum of the weight of the first water tank and the water in the first water tank is greater than the sum of the weight of the movable bracket, the pressure drive mechanism and the vehicle, the design of the counterweight is adopted in this solution to control the weight of the first water tank. When parking vehicles of different models, the parking of vehicles of different models can be achieved by changing the weight of the counterweight, thereby improving the practicality and scope of application of the present invention.

[0031] According to the solution of the present invention, a second water tank is also provided, and the second water tank is fixedly mounted on the main frame, the upper end of the second water tank is connected to the first water tank, and the lower end of the second water tank is connected to the water storage chamber, and the second water tank acts as a cache. In this solution, by introducing the second water tank, the water in the first water tank can be temporarily stored, and when the movable bracket returns to the initial position, the second water tank can introduce the water inside it into the water storage chamber. The design of this structure realizes the circulation of water in the first water tank, the second water tank and the water storage chamber.

[0032] According to the solution of the present invention, the micro-stereoscopic parking garage also includes a self-locking structure, which includes a guide rod and a push spring, and the guide rod is slidably mounted on the main frame in the horizontal direction. A pull ring is provided at one end of the guide rod, and a wedge is provided at the other end. The inclined surface of the wedge faces the movement path of the movable bracket, and the movable bracket is provided with a locking groove corresponding to the wedge. After the movable bracket slides to the specified position, the wedge enters the locking groove to form a self-locking structure that locks the movement of the movable bracket, thereby avoiding failures in the variable counterweight device or the water storage chamber, and preventing the pulley device from being unbalanced due to internal water leakage. The design of this structure can reduce safety hazards.

Through the design of this structure, it is possible to prevent the water in the water storage chamber from directly entering the second water tank through the third pipe.

[0050] Figure 1 A structural diagram of the present invention is schematically shown. Figure 1 As shown, this embodiment discloses a micro-stereoscopic parking garage provided by the present invention, including a main frame 100, a movable bracket 200, a variable counterweight device 300 and a pulley device 400, wherein the movable bracket 200 and the variable counterweight device 300 are respectively mounted on the main frame 100 in a sliding manner in the vertical direction. A pulley device 400 is provided at the upper end of the main frame 100, one end of the pulley device 400 is connected to the first water tank 310 in the variable counterweight device 300, and the other end is connected to the movable bracket 200. A water storage chamber 201 is provided in the movable bracket 200, and the first water tank 310 is connected to the water storage chamber 201 through a telescopic hose. A vehicle placement position is provided at the upper end of the movable bracket 200, and a vehicle can be parked at the vehicle placement position. When a vehicle is parked at the vehicle placement position, the gravity of the vehicle can drive the pressure drive mechanism 210, and press the water in the water storage chamber 201 into the first water tank 310. At this time, the sum of the weight of the first water tank 310 and the water in the first water tank 310 is greater than the sum of the weight of the movable bracket 200, the pressure drive mechanism 210 and the vehicle. Therefore, the first water tank 310 descends, and the movable bracket 200 drives the vehicle to rise. Further, a placement space capable of accommodating a second vehicle is formed below the movable bracket 200. The micro-stereoscopic parking garage proposed by the present invention has a compact structure, a clever design, and is easy to disassemble and assemble. It can be widely used in indoor or outdoor parking areas, greatly saving installation costs and improving space utilization. With the design of this structure, the water inside the movable bracket 200 is pressed into the first water tank 310 by the dead weight of the vehicle, thereby changing the gravity difference at both ends of the pulley device 400 to achieve the lifting of the vehicle, without the need for the drive of an electric motor or an internal combustion engine, and has a clever design, energy saving and environmental protection.

[0051] In some embodiments of the present invention, reference Figure 1There are two groups of pressure drive mechanisms 210, and the two groups of pressure drive mechanisms 210 are respectively arranged corresponding to the wheels on both sides of the vehicle. Each group of pressure drive mechanisms 210 includes a gravity pressure plate 211, a hydraulic plate 212 and a guide column 213. The gravity pressure plate 211 is connected to the hydraulic plate 212 through the guide column 213. The gravity pressure plate 211 is arranged on the upper end of the movable bracket 200, and the guide column 213 is slidably installed on the movable bracket 200 in the vertical direction. The hydraulic plate 212 is slidably installed in the water storage chamber 201 in the vertical direction. Specifically, a water storage chamber 201 is arranged in the movable bracket 200, and there is water in the water storage chamber 201. A hydraulic plate 212 is slidably installed in the water storage chamber 201 in the vertical direction, and the upper end of the hydraulic plate 212 is connected to the gravity pressure plate 211 through the guide column 213. In the initial state, the lower end of the movable bracket 200 is placed on the ground, and the upper surface of the gravity pressure plate 211 is higher than the upper surface of the movable bracket 200 due to the buoyancy of the water surface and the lifting effect of the return spring 214. The vehicle is parked on the upper end of the gravity pressure plate 211, and the water in the water storage chamber 201 can be pressed into the first water tank 310 by the dead weight of the vehicle. The design of this structure can convert the weight of the vehicle into a load and evenly transmit it to the hydraulic plate 212, so that the water in the water storage chamber 201 can be stably pressed into the first water tank 310, and the water in the water storage chamber 201 also has a buffering effect, avoiding excessive movement of the vehicle during the descent process and causing damage to the vehicle.

[0052] In some embodiments of the present invention, the weight of the water stored in the water storage chamber 201 is G1, G1=(0.08-0.12)G4, G4 is the weight of the vehicle. Specifically, in this embodiment, the stored water can be configured according to the weight of the vehicle to achieve the optimal lifting solution.

[0053] In some embodiments of the present invention, reference Figure 2 The pressure driving mechanism 210 further includes a return spring 214, the upper end of which abuts against the hydraulic plate 212, and the lower end of which abuts against the movable bracket 200. Specifically, when the vehicle leaves the upper end of the movable bracket 200, there is no water in the water storage chamber 201. By providing the return spring 214, the return spring 214 can push the hydraulic plate 212 upward, so that the water storage chamber 201 has enough space to accommodate water, so that the water storage chamber 201 can receive an external water source or an internal water source without providing additional pressure when injecting water to push the pressure driving mechanism 210 upward.

[0054] In some embodiments of the present invention, inclined plates 215 are rotatably provided at both ends of the gravity pressure plate 211; in the initial state: the lower end of the movable bracket 200 is placed on the ground, there is water in the water storage chamber 201, the hydraulic plate 212 floats on the water surface, and the upper end of the hydraulic plate 212 is connected to the gravity pressure plate 211 through the guide column 213. The gravity pressure plate 211 is supported by the buoyancy of the water surface and the return spring, and its upper surface is higher than the upper surface of the movable bracket 200. The vehicle is parked on the upper end of the gravity pressure plate 211, and the two ends of the gravity pressure plate 211 are respectively rotatably provided with inclined plates 215. Under the action of its own gravity, the inclined plate 215 is inclined to connect the ground and the gravity pressure plate 211, and the vehicle can enter the gravity pressure plate 211 through the inclined plate 215; in the working state: the gravity pressure plate 211 bears the weight of the vehicle, the gravity pressure plate 211 descends, and the water in the water storage chamber 201 is pressed into the first box body through the guide column 213 and the hydraulic plate 212, the height of the gravity pressure plate 211 gradually decreases and is lower than the upper surface of the movable bracket 200, the inclined plate 215 is limited by the movable bracket 200, and one end of the inclined plate 215 is tilted upward to form a safety baffle to prevent the vehicle from escaping from the gravity pressure plate 211. Through the design of this structure, the device of the present invention can be directly placed on the ground, and the vehicle can enter and exit the vehicle placement position at the upper end of the movable bracket 200 through the inclined plate 215. After the vehicle is parked at the vehicle placement position at the upper end of the movable bracket 200, the inclined plate 215 can rotate to form a safety baffle to prevent the vehicle from escaping. The design of this structure can improve the safety performance of the present invention and reduce safety hazards.

[0055] In some embodiments of the present invention, a counterweight block 320 is provided on the first water tank 310 of the variable counterweight device 300. The weight of the counterweight block 320 is G2, G3+G4-G1-G5<G2<G3+G4-G5, wherein G1 is the weight of the water in the water storage chamber 201, G3 is the sum of the weights of the movable bracket 200 and the pressure drive mechanism 210, G4 is the weight of the vehicle, and G5 is the weight of the first water tank 310. According to the solution of the present invention, a counterweight block 320 is provided on the first water tank 310. In order to ensure that the sum of the weights of the first water tank 310 and the water in the first water tank 310 is greater than the sum of the weights of the movable bracket 200, the pressure drive mechanism 210 and the vehicle, the design of the counterweight block 320 is adopted in this solution, so that the weight of the first water tank 310 can be controlled. When parking vehicles of different models, the parking of vehicles of different models can be achieved by changing the weight of the counterweight block 320, thereby improving the practicality and application scope of the present invention.

[0056] In some embodiments of the present invention, the micro-stereoscopic parking garage further includes a gravity safety locking mechanism 600, referring to Figure 5The gravity safety locking mechanism 600 includes a fixed block 610, a sliding rod 620, a swing arm 630, a cam 640 and a locking spring 650. The fixed block 610 is installed on the movable bracket 200, the sliding rod 620 is slidably installed on the fixed block 610, one end of the sliding rod 620 can enter or escape from the main frame 100, the swing arm 630 is rotatably installed on the movable bracket 200, the locking spring 650 is installed between the fixed block 610 and the swing arm 630, the upper end of the swing arm 630 is movably connected to the sliding rod 620, the cam 640 is rotatably installed on the movable bracket 200, one side of the outer edge of the cam 640 abuts against the lower end of the swing arm 630, and the other side abuts against the gravity pressure plate 211. In this embodiment, when no vehicle is parked on the gravity pressure plate 211, the sum of the weights of the movable bracket 200, the pressure driving mechanism 210 and the water stored in the water storage chamber is less than the sum of the weights of the counterweight 320 and the first water tank 310. Therefore, in this embodiment, a gravity safety locking mechanism 600 is provided, and when no vehicle is parked on the upper end of the gravity pressure plate 211, the gravity safety locking mechanism 600 can lock the movable bracket 200 on the main frame 100; when a vehicle is parked on the upper end of the gravity pressure plate 211, the gravity safety locking mechanism 600 can automatically unlock and work normally. It can avoid the gravity safety locking mechanism 600 being unlocked due to a fault or being unlocked accidentally by humans, which may cause safety accidents. Specifically, when a vehicle is parked on the upper end of the gravity pressure plate 211, the gravity pressure plate 211 begins to drop due to the gravity of the vehicle, and the gravity pressure plate 211 pushes the cam 640 to rotate. At the same time, the cam 640 drives the swing arm 630 to rotate. Further, the upper end of the swing arm 630 drives the slide bar 620 to move away from the main frame 100, so that the slide bar 620 is separated from the frame 100, and the automatic unlocking function is realized. When the vehicle is separated from the upper end of the gravity pressure plate 211, the gravity pressure plate 211 is lifted up by the reset spring 214. Further, the swing arm 630 is reset under the action of the locking spring 650, and then drives the slide bar 620 to be inserted into the main frame 100, so as to lock the main frame 100. It should be noted that the structure of the gravity safety locking mechanism 600 is smaller than that of the movable bracket 200, and will not affect the water pressure operation in the water storage chamber 201. In some embodiments of the present invention, a group of gravity safety locking mechanisms 600 are arranged under each wheel of the corresponding vehicle of the present invention. When the vehicle is completely parked on the gravity pressure plate 211, all the gravity safety locking mechanisms 600 are simultaneously in an unlocked state, and the movable bracket 200 can be completely unlocked from the main frame 100, thereby improving the safety performance of the present invention.

[0057] In some embodiments of the present invention, reference Figure 1 and Figure 2The present invention is also provided with a second water tank 330, which is fixedly mounted on the main frame 100, the upper end of the second water tank 330 is connected to the first water tank 310, the lower end of the second water tank 330 is connected to the water storage chamber 201, and the installation position of the second water tank 330 is higher than the water storage chamber 201. The second water tank 330 plays the role of buffering water. In this solution, by introducing the second water tank 330, the water in the first water tank 310 can be temporarily stored, and when the movable bracket 200 returns to the initial position, the second water tank 330 can introduce the water inside it into the water storage chamber 201 through the height difference. With the design of this structure, the circulation of water in the first water tank 310, the second water tank 330 and the water storage chamber 201 is realized.
