The present invention relates to a parking system, and more particularly, to a vehicle transport apparatus for automatically transporting and parking a vehicle to a parking space in the parking system, and a method of automatically transporting and parking a vehicle using the same.

      Automated parking systems are now widely used to efficiently park large numbers of vehicles in limited locations. The parking system is constructed of a structure such as a parking building or a parking tower having a plurality of parking spaces, and a transport and transport mechanism for inserting and removing a vehicle into an interior space.

    Most of these parking systems park vehicles using a so-called vehicle stand. In more detail, the entrance is opened when the vehicle stops on the floor near the entrance of the structure for parking. And the pallet is located on the floor inside the structure, so the operator must drive to the specified position on the pallet. The driver then exits the entrance and instructs parking using the operation panel installed at the entrance, and a transport mechanism such as an elevator carries the pallet carrying the vehicle. And the parking mechanism is completed by pushing the vehicle together with the pallet into the empty parking space. Therefore, all parking spaces in the structure are provided with pallets respectively. However, the commercial parking system using such a pallet has the following problems.

    First, it takes a lot of time to put the vehicle in or out of the parking system. For example, when placing a vehicle in a parking system, the transport mechanism must first move to an empty parking space and then to an entrance with an empty pallet. Moreover, when the parking system has to continuously put the vehicle into the parking space, time consumption is further intensified since the above-described process must be repeated. In addition, if the parking system removes the vehicles from the interior parking space, the transport mechanism must put an empty pallet of the first vehicle into the parking space before the first vehicle is removed and then the next vehicle is removed. Since it takes a long time to insert and remove the pallet, the time required to put the vehicle in or out of the parking system as a whole increases. As a result, the waiting time increases at the entrance of the parking system, resulting in congestion of the parking system entrance and causing inconvenience to drivers.

     8 is a system diagram of a hydraulic system used in an embodiment of the present invention. Hereinafter, with reference to Figure 8 describes the operation of the hydraulic system for operating the arm in accordance with the present invention. The hydraulic system shown in FIG. 8 includes an oil tank 350, a hydraulic pump and motor 320, an accumulator 360 for storing oil under a gas pressurized state, and a solenoid valve capable of opening and closing the valve in any direction as necessary. 371 and 373, a relief valve 372 for lowering the pressure by discharging oil when the pressure is equal to or greater than a predetermined pressure, a hydraulic control valve 374 for maintaining the hydraulic pressure in the cylinder during power failure, and a hydraulic cylinder 330.

     First, the operation of the hydraulic system when the arm is lifted and the wheel is raised is explained. First, the solenoid valves 371 and 373 and the hydraulic control valve 374 are opened in the direction of advancing the accumulator 360 and the cylinder 330 while the hydraulic pump 320 to which the motor is connected is operated. At this time, the oil filled in the accumulator 360 storing the oil under a gas pressure such as nitrogen is discharged at a high speed to operate the hydraulic cylinder 330 to rotate the arm at a high speed. Until the arm contacts the wheel of the vehicle, the arm rotates at high speed due to the pressure of oil released from the accumulator. When the arm contacts the wheel, the valve of the accumulator is closed and the hydraulic cylinder operates at a high pressure capable of lifting the wheel of the vehicle by the pressure of the hydraulic pump 320. When the arm is fully extended and the wheels of the vehicle are lifted, the solenoid valve to the hydraulic cylinder is closed and the accumulator's valve is opened so that the hydraulic pump fills the accumulator pressure and the pump stops when the accumulator reaches the predetermined pressure. Meanwhile, when lowering the wheel of the vehicle by folding the arm, the solenoid valves 371 and 373 and the hydraulic control valve 374 are opened in the direction in which the hydraulic pump operates and the hydraulic cylinder is reversed. When the rotary arm rotates and the wheel of the vehicle touches the pallet, the valve of the accumulator 360 is opened to release oil, which has been charged with gas pressure in the accumulator, at a lower pressure or a higher speed than the hydraulic pump, and thus the hydraulic cylinder ( 330 is reversed to allow the arm to fold quickly. When the arm is fully folded, the solenoid valve to the hydraulic cylinder closes and the accumulator's valve opens so that the hydraulic pump fills the accumulator pressure and the pump stops when the accumulator reaches the predetermined pressure.

     According to the present invention, when the load of the vehicle is not applied to the arm, that is, the arm is in contact with the wheel when lifting the vehicle, and after the wheel is in contact with the platform when the vehicle is lowered, the operating force is strong but the operating speed is slow Instead of the hydraulic oil, the arm of the accumulator, which has a relatively low operating force but a high operating speed, can operate the arm to effectively improve the operating speed of the vehicle transfer device and the processing capacity of the parking facility.

     On the other hand, as mentioned above, each of the carriages 100a and 100b is carried by lifting any one of the front wheels 1a and the rear wheels 1b of the vehicle 1, respectively. To this end, each arm 250a, 250b provided in each of the carriages 100a, 100b can accurately lift any one of the front wheels 1a and the rear wheels 1b of the vehicle 1, respectively. It is necessary that each of the carriages 100a and 100b be disposed in the correct position. Therefore, the vehicle transport apparatus D according to the present invention is provided with a sensor 270 for detecting the position of the wheels 1a and 1b of the vehicle 1, which will be described in more detail below.

     As shown in FIGS. 1 and 5C, the sensor 270 is provided between the supporter 200, more specifically, the arms 250a and 250b. Here, the sensor 270 may be formed of a sensor using light or ultrasonic waves so that the carriages 100a and 100b can detect the wheels 1a and 1b in close proximity to the wheels 1a and 1b. In this case, each of the carriages 100a and 100b stops after the predetermined time considering the moving speed after the sensor 270 detects the wheels 1a and 1b. It may stop in a position where it can engage the wheels 1a, 1b. In addition, in the embodiment of the present invention by detecting the distance between the two carriages in any one of the two carriages (100a, 100b) distance maintenance sensor for maintaining a constant distance between the two carriages during operation (Fig. 1, 271 Is preferably mounted. Thus, when two carriages move from one platform to another to transport the vehicle, the two carriages can be moved to a desired position at regular intervals without using a fastening device that combines the two carriages.

     The vehicle transport apparatus D according to the present invention equipped with the sensor 270 having the structure as described above may lift the wheels 1a and 1b of the vehicle 1 at the correct position by the following methods. The position of the wheels 1a and 1b of (1) is sensed.

     First, supporters 200 belonging to any one of the pair of carriages are engaged and pushed up while being unfolded on any one of the front wheel 1a and the rear wheel 1b of the vehicle 1. At this time, since the vehicle 1 is mounted at a predetermined position of the platform 10, the one carrier may stop after driving up to a predetermined position and the supporters 200 can accurately lift and lift the wheels. Will stop at.

     Next, the other carriage starts to move to the other pair of front wheels 1a and rear wheels 1b of the vehicle 1. Normally, the first carriage and the second carriage are held at a distance smaller than the front and rear wheel distances of the vehicle by the distance holding sensor 271. When the position of one carriage is determined, the other carriage is removed from the other carriage. The other wheel is detected using the sensor 270 while moving in a distant direction. During the movement, the sensor 270 installed on the other carrier detects the wheels 1a and 1b, and after a predetermined time has elapsed after the detection of the sensor 270, the arms 250a and 250b. The center of the wheel and the center of the wheel (1a, 1b) coincides, the other carriage stops. The supporters 200 belonging to any one of the other carriages can stably lift and transport any pair of the front wheels 1a and the rear wheels 1b of the vehicle 1 while being engaged. At this time, if the center of the arms (250a, 250b) of the supporter 200 and the center of the remaining wheels (1a, 1b) does not exactly fit, when the arms (250a, 250b) begins to unfold, at the same time carrying another one The brake of the geared motor which stops the stand is opened so that the carriage is automatically centered on the vehicle wheels 1a and 1b when the arms 250a and 250b are rotated.

     6A and 6B are cross-sectional views and a plan view of a parking system according to the present invention, and FIGS. 7A to 7G are schematic views showing each step of the vehicle automatic transfer method according to an embodiment of the present invention. Hereinafter, a method for automatically transferring a vehicle according to an exemplary embodiment of the present invention illustrated in FIGS. 7A to 7G will be described.

     As shown in FIG. 6A, when the vehicle 1 to be parked stops on the first platform 10a provided at the entrance 21 of the parking system, the vehicle transport device D is connected to the first platform 10a. Go to. Prior to this, the driver stops the vehicle in front of the entrance 21 of the parking system to be located on the first platform 10a. Then, the parking system is instructed to park the vehicle 1 using the operation panel installed at the entrance. At this time, the driver moves the wheels 1a and 1b of the vehicle 1 to a predetermined position of the first platform 10a so that the vehicle 1 can lift the vehicle 1 during subsequent operations. It is important to locate it. The parking system instructed thereafter opens the door 23 at the entrance 21 and then moves the vehicle transport device D to the first platform 10a located outside the parking system.

     Generally, the parking system has many parking spaces 25 therein as shown in FIGS. 6A and 6B, so that the entrance 21 and the respective parking spaces 25 are separated from each other and the entrance 21 is located. Carrying devices 31, 32 with a third platform 10c, as mentioned above, are used to carry the vehicle 1 to be parked from, to a certain parking space 25, or vice versa. Thus, the parking system moves the third platform 10c mounted on the conveying devices 31 and 32 toward the inlet 21, so that the conveying devices 31 and 32 after the door 23 is opened. The third platform 10c on the upper surface of the first platform 10a and the passages 15c and 15a of each other are connected to each other. As described above, the passages 15c and 15a are formed in common with the first and third platforms 10a and 10c to pass through the vehicle transport device D. Then, when the door 23 of the inlet 21 is opened, the vehicle transport device D is connected to the vehicle 1 on the first platform 10a from the third platform 10c via the passages 15c and 15a. Go down. In more detail, as shown in FIG. 1, the vehicle transport apparatus D is moved by a geared motor 140 and driving wheels 120 operatively connected thereto.

    When the vehicle transport device D moves to the first platform 10a, as shown in FIG. 7B, the vehicle transport device D may have some wheels of the vehicle 1 on the first platform 10a. For example, one of the front wheels 1a and the rear wheels 1b is lifted.

     At present, many cars are front wheel drive, and if the front wheel drive gear is in the state, its front wheels are difficult to rotate. And in most vehicles, when the front wheels are moved and rotated to some extent (Shimmying), the handle lock (Handle lock) occurs. Accordingly, the first carriage 100a of the vehicle transport device D preferably lifts the front wheels 1a of the vehicle 1 on the first platform 10a.

     Accordingly, as directed by the parking system, the supporter 200 of the first carriage 100a engages and continues to push the wheels of the vehicle 1, i.e., the front wheels 1a, to lift the wheels over the arm 250. Up. To this end, the rod 332 of the hydraulic cylinder 330 belonging to the first carriage 100a pushes out the rack gear 340, and the rack gear 340 rotates the idle gear 220. Let's do it. Then, arms 250a and 250b belonging to the first carriage 100a are horizontally rotated about the rotation axis 251, and are respectively spread to both sides of the vehicle transport apparatus D as shown in FIG. 7B. The wheels of the vehicle 1 are lifted up from the floor, respectively engaging the front and rear of the front wheels 1a of the vehicle 1. Thus, the front wheels 1a of the vehicle 1 fall away from the bottom of the first platform 10a, and the rear wheels 1b are supported on the bottom of the first platform 10a.

     When the first carriage 100a lifts the front wheels 1a of the vehicle 1, the parking system moves the second carriage 100b to the rear wheels of the vehicle 1 as shown in FIG. 7C. 1b). In this case, the second carriage 100b may be configured to position the rear wheels 1b of the vehicle 1 so that the second carriage 100b may be accurately positioned below the rear wheels 1b of the vehicle 1. While sensing, the vehicle approaches the rear wheels 1b of the vehicle 1. Then, the second carriage 100b detects the rear wheel 1b of the vehicle 1 by the sensor 270 provided in the supporters 200, and after a predetermined time passes, the center of the rear wheel is detected. Stop at the point.

At this time, the arms 250a and 250b moving together with the second carrier 100b belonging to the second carrier 100b are rotated horizontally as shown in 7d to rear wheel 1b of the vehicle 1. The rear wheels 1b are lifted from the bottom of the first platform 10a by raising the rear wheels 1b while being engaged.

As described above, when the wheels of the vehicle 1, that is, the front wheels 1a and the rear wheels 1b, are lifted by the hydraulic device 300 above the vehicle transport device D, the vehicle transport device D Moves to the second platform 10b provided in the parking space 25 in the parking system with the vehicle 1 lifted up as shown in FIG. 7E.

To this end, the vehicle transport device D firstly moves the vehicle 1 to a third platform 10c connected to the first platform 10a by the transport devices 31, 32. The door 23 of the parking system remains open, and the third platform 10c is also connected to the first platform 10a to stand by. Accordingly, the vehicle transport device D moves to the third platform 10c along the passages 15c and 15a communicated with each other by an instruction of the parking system.

Thereafter, the conveying devices 31 and 32 move the vehicle transport device D and the vehicle 1 mounted on the third platform 10c from the first platform 10a to the second platform 10b. To carry. When the conveying devices 31 and 32 reach the parking space 25, the third platform 10c and the second platform 10b are connected to communicate with the passages 15c and 15b of each other. The parking space 25 in which this second platform 10b is installed is generally open. During this conveyance process, it is unnecessary to put the vehicle 1 on the third platform 10c, so that the vehicle 1 remains in a lifted state by the vehicle transport device D.

When the third platform 10c and the second platform 10b are connected by the conveying devices 31 and 32, the vehicle transport device D is connected to the second platform 10b from the third platform 10c. And move along the passages 15c and 15b in communication with each other.

After the vehicle transport device D transports the vehicle 1 to the second platform 10b, the vehicle transport device D moves the vehicle 1 to the second platform as shown in FIG. 7F. Put it on (10b). To this end, the arms 250a and 250b are slowly rotated toward the main frame 110 in the opposite direction to slightly engage the wheels or fall off the wheels. At this time, the wheels of the vehicle 1 are lowered, in contact with the second platform 10b and fully supported by the second platform 10b. The arms 250a and 250b fold toward the respective carriages 100a and 100b as shown in FIG. 7F.

On the other hand, when the vehicle 1 parked in the parking space 25 in the parking system is taken out (taken out), all the above-described steps are performed in reverse. That is, the vehicle 1 is moved from the second platform 10b to the third platform 10c of the transportation devices 31 and 32 in a state lifted by the vehicle transport device D, and the third platform ( 10c is carried to the position of the first platform 10a of the inlet 21 of the parking system by the conveying devices 31, 32. Again the vehicle 1 is transported from the third platform 10c to the first platform 10a and then lowered on the first platform 10a so that it can be driven. All steps of leaving these vehicles are substantially the same as the steps described above, and thus the detailed description is omitted.

On the other hand, after the parking is completed, the vehicle transport device D is preferably returned to the third platform 10c. This is because the third platform 10c of the conveying devices 31 and 32 is located between the first and second platforms 10a and 10b so that the vehicle transport device D can be quickly removed when parking or unloading is requested. This is because it can move to the first and second platforms 10a and 10b. For the same reason, the vehicle transport apparatus D must be returned to the third platform 10c even after the discharging is completed.

In addition, in the above, an example in which the first platform 10a is provided at the entrance 21 of the parking system and the third platform 10c is provided at the conveying devices 31, 32 has been described. However, the present invention is not limited thereto, and the first platform 10a may be provided to the conveying devices 31 and 32. In this case, the third platform 10c is not provided separately, and the driver enters the vehicle 1 to the platform provided in the transport devices 31 and 32 located inside the door 23 when parking, It will be necessary to pull the vehicle 1 out of the parking system after entering the platform provided in the conveying devices 31 and 32 located inside the door 23.

     Although only a few embodiments have been described herein above, it will be apparent to those skilled in the art that the present invention may be embodied in many other specific forms without departing from the spirit and scope thereof. Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive, and thus, the present invention is not limited to the above detailed description, but may vary within the scope of the appended claims and their equivalents.

In a typical parking system, the pallet cannot move on its own and must therefore be manually inserted into or removed from the parking space by other devices. Moreover, the pallet itself is heavy and bulky. The pallet conveying speed is therefore relatively slow. On the other hand, in the present invention as described above, according to the optimized vehicle automatic transfer method, the small sized vehicle transfer device moves by itself with the vehicle loaded, and puts the vehicle into the parking space of the parking system or takes it out of the parking system. Therefore, the present invention shortens the time taken to put the vehicle in or out of the parking system. In addition, the vehicle transport apparatus can move to the standby position for subsequent operation, ie the transport apparatus, as soon as the indicated operation (for example, parking operation) is finished, since it can move by itself. In addition, compared to a general parking system, the present invention does not require the removal of the empty pallet or the empty pallet back into the parking space. These features enable the vehicle to be continuously inserted into or taken out of the parking system and further reduce the time it takes to insert or withdraw the vehicle. As a result, this reduction in time according to the invention leads to a reduction in waiting time at the entrance of the parking system, which makes the driver more convenient. In addition, in the present invention, the vehicle transfer device directly transfers the vehicle from the outside to the inside of the parking system or from the inside to the outside, which makes the user more convenient.

On the other hand, the vehicle transport apparatus of the present invention has a small and simple structure. Therefore, there are few failures and malfunctions, and installation and maintenance costs are low. In addition, the vehicle is driven by a motor, and the vehicle is lifted or lowered by a hydraulic device, so that vibration and noise are less generated during operation.
