DETAILED DESCRIPTION

[0052] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0053] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0054] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0055] like Figure 1 and Figure 2 As shown, the stereo garage in the prior art includes frame columns 2, frame beams 3, parking passages and parking spaces. An elevator car 1 is arranged in the parking passage, parking spaces are not allowed to be arranged in the parking passage, and the car plate 4 can only move in one direction. Figure 1 The wheel plate 4 in the vehicle can only move longitudinally. Figure 2 The car plate 4 in the figure can only move horizontally, and the parking passage needs to occupy three empty spaces, which has low space utilization. The arrow in the figure indicates the direction in which the car plate 4 can move. The three-dimensional parking garage includes a ground floor and a multi-story parking floor. The ground floor is generally used for inputting and outputting vehicles, and the parking floor is used for parking vehicles. Both the ground floor and the parking floor are provided with lifting positions, and the ground floor is connected to the parking floor through a lift.

[0056] like Figure 3 , Figure 4 and Figure 5 As shown, a high-density and efficient car storage and retrieval stereo garage includes a stereo garage body, an elevator and a vehicle plate moving structure, wherein the vehicle plate moving structure includes a power unit 13, which is mounted on a bracket 26 of the stereo garage and is located below the vehicle plate 4, and includes a direction adjustment mechanism and a running mechanism, which are connected to the direction adjustment mechanism and are used to control the running direction of the running mechanism, and the running mechanism is used to drive the vehicle plate 4 to move longitudinally or transversely, and the vehicle plate 4 is in contact with the running mechanism. The vehicle plate 4 itself has no power, and the elevator includes an elevator car 1, on which the power unit 13 is also provided.

[0057] The direction adjustment mechanism includes a first motor 6, a gear assembly and a support platform 9. The gear assembly includes a driving gear 7 and a driven gear 8. The driving gear 7 is located on one side of the driven gear 8 and meshes with the driven gear 8. The driving gear 7 is coaxially connected to the rotating shaft of the first motor 6. The driving gear 7 is located above the first motor 6. The support platform 9 is fixedly connected to the central axis of the driven gear 8. The support platform 9 rotates synchronously with the driven gear 8. The support platform 9 is located above the driven gear 8. The support platform 9 is connected to the operating mechanism.

[0058] The operating mechanism includes a second motor 10 and a roller 11. The second motor 10 is fixed on the support platform 9. The roller 11 is coaxially connected to the rotating shaft of the second motor 10. The central axis of the roller 11 is parallel to the connecting line of the center of the driving gear 7 and the center of the driven gear 8. The outer ring of the roller 11 is in contact with the wheel plate 4. The operating mechanism as a whole can rotate around the center of the driven gear 8 following the support platform 9, thereby realizing the conversion of the roller 11 being arranged horizontally or vertically.

[0059] like Figure 5 As shown, a plurality of power units 13 are installed on each layer of the bracket 26 of the stereo garage. The plurality of power units 13 are arranged in a row, and the plurality of power units 13 are used to support and drive the vehicle disc 4 to move horizontally or vertically. Figure 5 The rollers 11 of the power unit 13 are all arranged horizontally. If the vehicle plate 4 of a certain parking space needs to move horizontally, the second motor 10 of the power unit 13 is directly started, and the vehicle plate 4 moves horizontally under the rolling action of the rollers 11. If the vehicle plate 4 of a certain parking space needs to move longitudinally, the first motor 6 needs to be started first, and after the rollers 11 of the power unit 13 are adjusted to be arranged longitudinally, the first motor 6 is stopped, and the second motor 10 is started, and the vehicle plate 4 moves longitudinally under the rolling action of the rollers 11.

[0060] like Figure 6 As shown, a guide wheel 12 is also provided on the bracket, and the central axis of the guide wheel 12 is parallel to the central axis of the driving gear 7. The guide wheel 12 is used to assist in limiting the moving direction of the vehicle disc 4. The guide wheel 12 and the power unit 13 are staggered and do not affect each other, nor do they affect the normal longitudinal or lateral movement of the vehicle disc 4. With the assistance of the guide wheel 12, the stability of the movement of the vehicle disc 4 is improved. And because each roller 11 is controlled by a separate power unit 13, they do not affect each other, have strong fault compatibility, and are simple and convenient to maintain. When an individual roller 11 fails, it does not affect the normal movement of the vehicle disc 4. On the other hand, the number of rollers 11 is not limited by the power unit 13, and the power unit 13 has a simple structure and is easy to install, which increases the number of rollers 11 installed, that is, improves the transportation efficiency and transportation stability of the vehicle disc 4.

[0061] like Figure 7 As shown, Figure 1 and Figure 2 Compared with the prior art solutions, by using the power unit 13 in this embodiment to control the conversion of the vertical and horizontal movements of the vehicle disc 4, each parking floor of the three-dimensional garage only needs to reserve one lifting position and one exchange position 14. The elevator car 1 passes through the lifting position, and the rest can be used as parking spaces. There is no need to vacate the parking passage, which reduces the space occupied by the lifting position and the setting of the lifting equipment, reduces the cost of the three-dimensional garage, increases the number of parking spaces, and improves the utilization rate of the three-dimensional garage space.

[0062] The position of the exchange position 14 changes with the movement of the vehicle disc 4 on the parking layer. The bracket on the exchange position 14 is provided with a power unit 13 but no vehicle disc 4.

[0063] like Figure 8-Figure 11 As shown, based on the setting of the above-mentioned power unit 13, the layout of the first floor of the garage and the entrance and exit positions can be flexibly set according to the garage environment requirements.

[0064] Compared with the existing technical solutions, based on the setting of the above-mentioned power unit 13, the number of parking spaces on each parking floor of the three-dimensional parking garage can be increased without affecting the normal storage and retrieval of vehicles. Each parking floor is arranged in three horizontal and three rows with 7 parking spaces, 1 exchange position 14 and 1 lifting position, and the 1 lifting position is located in the center.

[0065] Furthermore, each floor of the three-dimensional car park of the present invention is provided with 8 detection switches, and when the vehicle plate touches the switch, the position of the vehicle plate can be detected. The detection switch includes a travel switch, a proximity switch or a photoelectric switch. The present invention preferably uses a photoelectric switch, and a reflective lens is attached to the bottom of the vehicle plate to achieve accurate detection of the position of the vehicle plate 4.

[0066] The vehicle picking method of the present invention is:

[0067] S01. Each floor of the three-dimensional parking garage reserves an exchange position 14. The car plate 4 in this floor moves longitudinally or transversely around the lifting position (except the car plate 4 in the elevator car 1 cannot be moved). The car plate 4 that needs to take the car is moved to the left, right, up, down and four directions of the lifting position in advance, close to the lifting position;

[0068] S02, after the elevator car 1 is lifted to the parking floor where the vehicle to be picked up is located, the vehicle plate 4 carrying the vehicle to be picked up is moved onto the elevator car 1 under the action of the power unit 13, and the vehicle is picked up.

[0069] The parking method of the present invention is:

[0070] After the car plate 4 carrying the vehicle to be stored on the first floor enters the elevator car 1, the photoelectric switch detects the parking space on the parking floor, and then feeds back the parking space information to the PLC. The PLC controls the parking space to move to the surroundings of the lifting position in advance. After the elevator car 1 is lifted into place, the PLC controls the corresponding power unit 13 to start, and translates the car plate 4 on the elevator car 1 into the parking space to complete the parking.

[0071] like Figure 12-14 As shown, the present invention provides two vehicle picking embodiments and one vehicle storage embodiment.

[0072] Fig.12 In the game, you need to take the vehicle on the No. 7 plate in the lower right corner:

[0073] S11, after receiving the instruction, the PLC finds the most convenient way to move the wheel plate 4, controls the corresponding power unit 13 to work, and uses the first motor to adjust the direction of the roller 11 under the wheel plates 4 and 7 and the target position to the longitudinal direction;

[0074] S12, after adjusting the direction of the roller 11, start the corresponding second motor to move the No. 4 and No. 7 discs upwards, so that the No. 7 disc is moved to the side of the lifting position;

[0075] S13, adjust the direction of the rollers below the current No. 7 car plate and on the elevator car 1 to be horizontal, move the No. 7 car plate to the left to the elevator car 1, and then drive the No. 7 car plate to move to the first floor through the elevator, so that the No. 7 car plate is ready for picking up the car.

[0076] Fig.13 In the process, if you need to take the vehicle on the No. 5 plate at the lower left corner, first move the No. 1 and No. 2 plates to the right at the same time, then move the No. 3 and No. 5 plates upward at the same time, and then move the No. 5 plate to the left horizontally to the lifting position, and then use the elevator to drive the No. 5 plate to move to the first floor, and the vehicle on the No. 5 plate is taken.

[0077] Fig.14 In the process of storing a vehicle on the No. 5 disc in the lifting position, or resetting the No. 5 disc, there are two empty spaces at the lower left corner and the upper right corner. First, move the No. 6 disc horizontally to the right, and then move the No. 5 disc vertically downward to complete the return or storage of the No. 5 disc. The specific steps are:

[0078] S21, setting the car to be stored in the No. 5 parking plate, after receiving the instruction, the PLC finds the most convenient parking method, controls the power unit 13 under the No. 6 parking plate and the target position to work, and uses the corresponding second motor 10 to adjust the direction of the roller 11 to the horizontal direction;

[0079] S22, move the No. 6 parking plate to the left, leaving a parking space next to the lifting position;

[0080] S23, after adjusting the rollers under the No. 5 wheel plate and the target position to be in the longitudinal direction, the No. 5 wheel plate is moved to the side of the lifting position.

[0081] by Fig. 9 Taking the first-floor entrance and exit setting mode of the stereo garage as an example, the overall parking process of the present invention is described:

[0082] first, Fig. 9Two garage entrances 15 and two garage exits 22 are respectively arranged at both ends of the first floor of the medium-sized garage, and the first space, the second space and the third space are arranged in sequence from the garage entrance 15 to the garage exit 22. The first space is provided with two parking halls 17 connected to the two garage entrances 15 respectively. A lifting position is arranged in the middle of the second space, and transition positions are arranged on both sides of the lifting position. The third space is provided with two car pickup halls connected to the two garage exits 22 respectively. The transition position is used to move the vehicle in the parking hall 17 to the elevator car 1, or to move the vehicle in the elevator car 1 to the car pickup hall 20. The parking hall 17, the transition position and the car pickup hall 20 are all provided with power units.

[0083] The overall parking process of the present invention:

[0084] S01, the car arrives at the garage entrance 15, the ground sensor car is waiting at the door, and detects that there is a car plate 4 in the parking hall 17, and there is no car on the car plate 4, and the first outer door 16 is opened;

[0085] S02, the car enters the parking plate 4 in the parking hall 17, and the length and width of the car are detected by photoelectric detection, and the driver is reminded to adjust the position of the car by voice broadcast;

[0086] S03, judging whether the car is parked in place by detecting the front wheels;

[0087] S04. Use photoelectric or ultrasonic detection to measure the length, width and height of the vehicle, and use underground weighing to measure the weight of the vehicle to see if it meets the size and weight requirements for vehicles suitable for parking in this parking garage;

[0088] S05. The driver parks the car and walks to the operation screen outside the door to confirm the parking. The confirmation can be made through license plate recognition, face recognition, or mobile phone QR code.

[0089] S06, after the detection system of the parking hall 17 detects that the car is suitable for parking, the first inner door 18 opens;

[0090] S07, the wheel plate 4 first moves horizontally to the right or left;

[0091] S08, the car plate 4 is aligned with the center line of the first inner door of the parking hall 17. After the car plate 4 is detected to be in place and the elevator car 1 is detected to be in place, the power units 13 installed on the parking hall 17 and the transition position 1 simultaneously receive instructions from the PLC to adjust the direction of the roller 11 of the corresponding power unit 13 to the longitudinal direction;

[0092] S09, after the roller 11 rotates into position, the roller 11 runs, moves the car plate 4 longitudinally to the transition position, and then further adjusts the transition position and the roller direction on the elevator car 1 to be horizontal, moves the car plate 4 to the elevator car 1, and after the car plate 4 is detected to be in position, it rises to the parking floor.

[0093] S10, on each parking floor, each parking plate 4 detects the positions of all parking plates through photoelectric detection.

[0094] S11, during the ascent of the elevator car 1, the PLC detects that there are two empty spaces without parking discs 4 on a certain floor, and the PLC issues a movement command to the parking disc on that floor, so that it moves horizontally to make room for the parking spaces near the lifting position.

[0095] S12, after the elevator car 1 rises to the corresponding parking floor, it detects a parking space without a parking plate, and translates the parking plate in the elevator car 1 to the parking space on that floor, completing the parking process.
