Description

Technical Field

[0001] The invention relates to a parking garage, in particular to a three-dimensional parking garage. Background Art

[0002] With the development of society, the number of cars is increasing. The contradiction between the increasing number of cars and the limited parking space is becoming more and more serious. "Parking difficulty" has become a prominent phenomenon brought about by the rapid growth of automobile consumption. It is under this severe situation that the research on stereo garages came into being. Stereo garages can make good use of the limited space above the ground and become an effective way to solve the problem of static traffic in cities. my country's stereo garage parking industry and its supporting industries are currently becoming a promising industry with great potential. However, due to the influence of technology and various factors, stereo garages have not been widely used at present.

[0003] Chinese patent CN202672812U discloses a vertical circulation stereo parking garage (see attached Figure 1 ), mainly composed of 5 parts: steel structure part, transmission part, pallet part, pallet track part, power part, which drives the pallet support plate of the transmission part to rotate up and down through the power output and transmission of the motor and reducer of the power part; the pallet roller slides up and down in the pallet track and ensures the balance of the vehicle loading plate. In this patent, a single motor is used as the power source to control the chain rotation.

[0004] Many of the vertical stereo garages disclosed in the prior art are similar to the technical solutions disclosed in the above patents (or adopt a structure similar to a "windmill"), with a single central core motor as the rotational power. In this way, the central core motor often bears the rotational kinetic energy of all the compartments and has a large output. In addition, since the parking compartments are generally allocated in sequence during use, there will be a situation where all vehicles are parked in the compartment on the same side, while the compartment on the other side is completely empty, then the motor will have to bear the power to lift all vehicles. For example: if the stereo garage has a 5-story garage structure, and all 5 existing vehicles are parked on one side of the stereo garage, the output power of the central core motor must at least support the lifting of objects weighing nearly 10 tons. This results in the motor selection having to be a high-power motor, resulting in the problem of high energy consumption; and the use of high-power motors will bring greater noise pollution.

[0005] Based on the above problems, the present invention provides a technical solution to better overcome at least one of the above problems. Summary of the invention

[0006] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0007] To this end, an object of the present invention is to provide a three-dimensional parking garage with simple structure, high reliability and high safety, the three-dimensional parking garage comprises a top unit, a bottom unit, a middle unit and a parking box, the middle unit is divided into a front middle unit part and a rear middle unit part or a left middle unit part and a right middle unit part, the number of layers of the middle unit is greater than or equal to 1, and the parking box is installed inside the front middle unit part and the rear middle unit part or the left middle unit part and the right middle unit part among the top unit, the bottom unit and the middle unit;

[0008] The parking box has an independent motion coupling device, and the three-dimensional parking garage has a circulation system installed on the three-dimensional parking garage. The motion coupling device is connected to the circulation system and drives the parking box to perform forward and backward circulation movement or left and right circulation movement in the three-dimensional parking garage.

[0009] When the three-dimensional parking garage is in operation, the parking box in the bottom unit at the initial position on the bottom floor moves to the bottom of the first middle unit of the garage under the action of the circulating movement system, and then makes a vertical upward movement together with other parking boxes on the side of the first middle unit under the action of the circulating movement system; at the same time, the parking box in the top unit at the initial position on the top floor moves to the top of the second middle unit of the garage under the action of the circulating movement system, and then makes a vertical downward movement together with other parking boxes on the side of the second middle unit under the action of the circulating movement system; under the action of the circulating movement system, the parking box located in the bottom unit moves up and enters the first middle unit on the first floor, and the parking box located in the first middle unit moves up and enters the first middle unit on the first floor. The parking box in the first middle-layer unit moves up to the first middle-layer unit on the second layer, and so on, the parking box in the first middle-layer unit on the nth layer enters the top-layer unit; the parking box in the top-layer unit moves down to the second middle-layer unit on the nth layer, and the parking box in the second middle-layer unit on the nth layer moves down to the second middle-layer unit on the n-1th layer, and so on, the parking box in the second middle-layer unit on the 1st layer enters the bottom-layer unit; then, the parking box entering the top-layer unit moves to the top-layer initial position under the action of the circular motion system, and the parking box entering the bottom-layer unit moves to the bottom-layer initial position under the action of the circular motion system.

"Parking difficulty" has become a prominent phenomenon brought about by the rapid growth of automobile consumption. It is under this severe situation that the research on three-dimensional parking garages came into being. Three-dimensional parking garages can make good use of the limited space above the ground and become an effective way to solve the problem of urban static traffic. my country's three-dimensional parking garage parking industry and its supporting industries are currently becoming a promising industry with huge potential. However, due to the influence of technology and various factors, three-dimensional parking garages have not been widely used at present; and a three-dimensional parking garage designed by the present invention is connected with the circulation system through the motion coupling device and drives the parking box to perform forward and backward circulation movement or left and right circulation movement in the three-dimensional parking garage. The three-dimensional parking garage is driven by discrete motors to circulate the parking box. The discrete motors are multiple small motors that jointly apply force at corresponding positions. Multiple small motors are placed at multiple specific positions. The large motor driving the overall rotation in the original technology is replaced by multiple motors placed at multiple specific positions to jointly apply force. It has a simple structure, small footprint, and a stable and safe box, so it has obvious advantages.

[0011] In addition, the mobile parking box disclosed in the present invention also has the following additional technical features:

[0012] Further, the circulation system includes a top circulation system installed in the top unit, a front middle circulation system and a rear middle circulation system or a left middle circulation system and a right middle circulation system installed in the front middle unit part and the rear middle unit part or the left middle unit part and the right middle unit part in the middle unit, and a bottom circulation system installed in the bottom unit;

[0016] Furthermore, the three-dimensional parking garage is driven by discrete motors working together to drive the parking box to circulate. The discrete motors are multiple small motors that jointly apply force at corresponding positions. Multiple small motors are placed at multiple specific positions.

[0019] The present invention adopts a distributed motor arrangement method to distribute motors in each parking box, and every two motors jointly drive a matching chain, and the motors and chains are symmetrically distributed in the first middle-layer unit and the second middle-layer unit of the middle-layer unit. When the operation of the chain meets the conditions: the operation speeds of all the chains are consistent, wherein the operation directions of the two chain groups arranged on the n-layer first middle-layer unit and the n-layer second middle-layer unit on opposite sides are the same, and the operation direction of the chain group arranged on the vertical dividing plane in the middle of the middle-layer unit is opposite to the operation direction of the other two chain groups, it is ensured that during the operation of the system, the movement speeds of the various parking boxes remain consistent, so that the vehicles therein can be parked stably, and the parked vehicles can be picked up and unparked sequentially. At the same time, the distributed motor arrangement method effectively avoids the damage of instantaneous start-up of the single-core motor as a starting power source, and the start-stop operation speeds are both fast, and the motor power and energy consumption are reduced. Since the motor working noise is positively correlated with the power, the generation of working noise is reduced, which is beneficial to human-computer interaction.

[0024] Furthermore, the upper structure and the lower structure of the parking box body are mutually interlocking structures, and the parking box body is mutually interlocking and locked up and down on either side of the middle unit.

[0025] Furthermore, the upper structure of the parking box body has a groove structure, and the lower structure of the parking box body has a locking claw structure that engages and locks with the groove;

[0026] or

[0028] The number of grooves and locking claws corresponds one to one, and the grooves and locking claws cooperate with each other to grasp the adjacent parking boxes, and the locking claws are electromagnetically controlled to grasp and release. When two parking boxes are stacked vertically, if the bottom locking claws of the upper parking box grasp the grooves on the top of the lower parking box, the two parking boxes can be locked to facilitate movement in the same direction, and maintain stability during the same-direction movement, ensuring the safety of the vehicle in the parking box.

[0029] The present invention adopts a modular design. The purpose of setting the concave structure and the convex structure is to achieve stable stacking. The modular design allows the height of the entire garage to be increased or decreased according to the actual traffic flow while achieving stable stacking, that is, the size of the garage is designed according to the traffic flow, which greatly saves costs.

[0030] Furthermore, the transmission gear is fixed to the eight vertex corners of the parking box, and the transmission chain is meshed with the transmission gear.

[0031] Preferably, the transmission gear is provided with a buffer layer with relatively large elasticity on the basis of the shock-absorbing alloy, which can be an alloy with a larger elastic coefficient or an alloy material such as strong rubber.

[0032] A transmission gear is arranged at each of the eight top ends of the parking box to ensure the stability and speed of the parking box during operation.
