Description

[0002] With the acceleration of urbanization and the continuous increase in the number of cars, parking difficulties have become a common problem faced by many cities. Especially in the city center, due to the shortage of land, the contradiction between supply and demand of parking spaces is more prominent. Therefore, as a new parking method, intelligent three-dimensional parking garages are gradually favored by people for their high efficiency, convenience and safety.

[0003] At present, intelligent three-dimensional parking garages have been widely used. These parking garages use advanced automatic control and mechanical transmission technology to identify vehicle information through license plate recognition systems or card swiping systems, and automatically allocate an available parking space. Then, by sending instructions to the lifting, lateral movement, rotation and other actuators, the vehicle is moved to the target location. However, how to ensure the stability and safety of the vehicle during parking is still an important issue that needs to be solved by intelligent three-dimensional parking garages.

[0004] For example, a smart garage entry and exit detection alarm system disclosed in a Chinese invention patent with application publication number CN109972887A includes a sensor module, a control box and a smart garage body, wherein the sensor module is arranged at the front end of the smart garage body, and the control box is arranged at the rear end of the smart garage body. The sensor module consists of a fixed frame, a first sensor and a second sensor, wherein the first sensor and the second sensor are fixed in the fixed frame in sequence, and the fixed frame is fixedly linked to the smart garage body.

[0031] On the basis of the above-mentioned implementation mode, the baffle plate 1 311 and the baffle plate 2 321 are both hinged to the inner walls on both sides of the clearance groove 5 through hinges, and the hinges are arranged along the width direction of the bottom plate 2 .

[0032] Specifically, the hinge includes a pin disposed between the baffle plate 1 311 or the baffle plate 2 321 and the bottom plate 2 , and the baffle plate 1 311 or the baffle plate 2 321 rotates along the pin under the action of an external force.

[0033] Specifically, four give-way grooves 5 are provided in the present invention, two of which are provided in front of and behind the front wheels of the vehicle, and the other two are provided in front of and behind the rear wheels of the vehicle. A baffle 1 311 is provided in front of the front wheel and the rear wheel, and a baffle 2 321 is provided behind the front wheel and the rear wheel. When the vehicle is parked, the baffle 1 311 and the baffle 2 321 rotate in opposite directions, respectively, and rotate upward to approach the wheels and finally clamp the wheels.

[0034] Based on the above implementation, Figure 4 , Figure 5 As shown, the driving unit 4 includes a motor 1 and a motor 2, wherein the motor 1 is connected to two baffles 1 311 through the rotating component 1 31, and the motor 2 is connected to two baffles 2 321 through the rotating component 2 32, and the motor 1 and the motor 2 are both connected to the bottom surface of the bottom plate 2, and the output ends of the motor 1 and the motor 2 are both provided with a double-groove pulley 1 43, and the belt 1 41 and the belt 2 42 are respectively connected to the groove 1 in the double-groove pulley 1 43. The other ends of the belt 1 41 and the belt 2 42 are connected to the double-groove pulley 1 Pulley No. 2 44, the double-groove pulley No. 2 44 and belt No. 3 45 are belt-driven, the other end of the belt No. 3 45 drives baffle No. 1 311 and baffle No. 2 321 to rotate through a rotating assembly, the rotating assembly includes a double-groove pulley No. 3 46 connected to the belt No. 3 45, the baffle No. 1 311 and the baffle No. 2 321 have through holes 49 arranged along the length direction of the base plate 2, the double-groove pulley No. 3 46 is wrapped with a rope 48, the other end of the rope 48 passes through the through hole 49 and is connected to the baffle No. 1 311 and the baffle No. 2 321.

[0035] Preferably, the double-groove pulley 2 44 is connected to the bottom surface of the base plate 2 through a fixed plate 1 441, the double-groove pulley 2 44 is driven by a belt 3 45, there is a certain angle between the belt 3 45 and the base plate 2, and a movable gap 451 is provided on the bottom surface of the base plate 2 for the belt 3 45 to pass through, the other end of the belt 3 45 is connected to a double-groove pulley 3 46, and the double-groove pulley 3 46 is connected to the inner wall of the give way slot 5 through a fixed plate 2 461.

[0036] Specifically, when there is no car in the parking space, the rope 48 is in a lengthened state, and the baffle 1 311 and the baffle 2 321 are blocked in the give way groove 5 under the action of gravity, and remain parallel to the bottom plate 2. When there is a car in the parking space and the driver has left the parking space, the rope 48 is shortened, and the baffle 1 311 and the baffle 2 321 form a certain angle with the bottom plate 2. The baffle 1 311 and the baffle 2 321 are respectively clamped on the front and rear sides of the vehicle wheels to ensure that the vehicle will not be displaced.

[0037] Based on the above implementation, Figure 6 As shown, the inner wall of the give way groove 5 is provided with a spring 51 for preventing the baffle 1 311 and the baffle 2 321 from excessively rotating downward. There are a plurality of springs 51, and the springs 51 are arranged on the opposite side of the hinge axis. When there is no car in the parking space, the baffle 1 311 or the baffle 2 321 is parallel to the bottom plate 2, the bottom surface of the baffle 1 311 or the baffle 2 321 rests on the spring 51, which not only reduces shock but also plays a stopping role to prevent the baffle 1 311 or the baffle 2 321 from continuing to rotate downward. The spring 51 can also assist in lifting the baffle 1 311 and the baffle 2 321 to avoid the mechanism from getting stuck.

[0038] Based on the above implementation, Figure 7 As shown, the sensing unit 6 includes a box body 61 arranged along the length direction of the base plate 2, a screw pair is connected inside the box body 61, and a sensor 63 is connected to a moving nut 62 of the screw pair. The sensor 63 moves with the vehicle to prompt the parking position of the vehicle. The sensor 63 is connected to the control screen 12 arranged on the lifting bracket 1, and the screw pair is connected to the servo motor. The servo motor drives the screw of the screw pair to rotate, and the moving nut 62 makes a linear motion along the screw. The moving nut 62 drives the sensor 63 to move. The sensor 63 moves with the vehicle and senses the situation in the garage, and sends an electrical signal to the control screen 12.

[0039] Specifically, a relay is installed inside the motor and the servo motor to receive the start / stop signal sent by the control panel 12 and control the rotation direction of the motor and the servo motor.

[0040] Specifically, the sensing unit 6 also includes a second sensor 64 arranged on the lifting bracket 1, and the second sensor 64 is used to monitor vehicles passing through the garage door.

The speaker in the voice broadcast unit 13 can broadcast the status of the parking space, and the camera in the camera unit 14 can shoot and record the vehicle status.

[0043] The method of use of the present invention is as follows: The camera in the camera unit 14 recognizes the vehicle and sends a signal to the control screen 12. The control screen 12 starts the sensor 63. When the sensor 63 detects that the vehicle passes by, it starts the servo motor to drive the sensor 63 to move, so that the sensor 63 follows the vehicle to remind the parking position of the vehicle. After the vehicle stops, the driver gets off the vehicle. The sensor 2 64 detects that the driver leaves the garage and transmits a signal to the control screen 14. The control screen 14 starts two motors, which drive the double-groove pulley 43 to rotate. Pulley one 43 drives belt one 41 and belt two 42 to rotate, belt one 41 drives double-groove pulley two 44 to rotate, and double-groove pulley two 44 drives belt three 45 to rotate. When the rope 48 wrapped around the double-groove pulley three 46 is shortened to the shortest, the rope 48 pulls baffle one 311 to rotate until the vehicle wheel is clamped. The same is true for baffle 321. Baffle one 311 and baffle 321 are clamped at the front and back of the vehicle wheel respectively, effectively fixing the parking position of the vehicle wheel, preventing the vehicle from displacement and keeping the vehicle stable.
