Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent parking, in particular to an intelligent stereo garage elevator with automatic centering and rotating functions and a stereo garage. BACKGROUND

[0002] With the development of society and the improvement of people's living standards, motor vehicles have become the main means of transportation for people. With the increase in the number of vehicles, parking places are in short supply. In order to solve the problem of parking, people have designed mechanical stereo garages with various structures. Mechanical stereo garages make rational use of three-dimensional space, stack multiple three-dimensional parking spaces upward, have outstanding land-saving advantages, have greater parking capacity compared with ordinary ground parking spaces or underground garages, and occupy less ground area. In more and more public places, this kind of mechanical stereo garage has begun to be popularized.

[0003] The existing stereo garage is often designed as multiple layers. When parking a car in the stereo garage, the car needs to be lifted and transported by a vertical lifting transporter. The vertical lifting transporter generally has a rotating function, a lifting function, a centering function, a transporting function, etc. The vertical lifting transporter realizes lifting and transverse movement to park the car on the parking frame on both sides of the shaft, so as to park the car. However, the existing vertical lifting transporter still has the following disadvantages:

[0004] 1. The rotating function is to change the direction of the vehicle to facilitate the vehicle to drive out. At present, a turntable is generally used to realize this function. However, the turntable occupies a large space, and with the change of the parking position of the vehicle, the turntable will deviate during rotation. Long-term use will cause damage to the turntable, which needs to be repaired regularly. This not only increases the workload and use cost of the staff, but also has certain safety hazards.

[0005] 2. The centering function is to correct the parking position of the parked vehicle, so that the central axis is aligned with the central axis of the vehicle carrier, so that the mechanical parking space is evenly stressed, and the equipment runs stably. The existing transporter generally uses a gear and rack pushing mechanism to realize the pushing centering function. This mechanism has compact structure, reliable transmission, and high mechanical efficiency. However, the gear, rack and gear box assembled with the gear have high manufacturing precision, positioning precision and assembly precision, so the manufacturing cost and assembly cost are high.

[0006] 3. Traditional multi-level parking garages have limited parking areas at their vehicle entrances and exits. The width of the parking platform is restricted, requiring high driving skills and making it inconvenient for drivers to park on the platform. Furthermore, there are width restrictions on vehicles waiting to be parked. If a vehicle is too wide, especially if it is slightly smaller than the width of the parking area on the platform, it becomes difficult to park on the platform, thus preventing the use of multi-level parking garages. This limits the applicability of existing multi-level parking garages and prevents them from achieving truly seamless parking.

[0007] In order to solve the above-mentioned technical problems, the applicant hereby proposes an intelligent automated parking system lift and automated parking system with automatic centering and rotation functions. Summary of the Invention

[0039] Referring to Figures 1-8 The present application provides an intelligent stereo garage elevator with automatic centering and rotating function, comprising a control unit, a lifting frame 1, a rotating mechanism 2 and a rotating bracket assembly 3.

[0040] The rotating bracket assembly 3 is the main functional assembly of the application, and is used for bearing, rotating and centering the vehicle, and comprises a bearing frame 309, a first roller group 303, a second roller group 307, a first driving assembly and a second driving assembly. The bearing frame 309 is used for bearing, and is made of a steel frame structure with excellent stress resistance. First, second, third and fourth cross beams 301, 304, 306 and 308 are fixed on the top of the bearing frame 309 in parallel along the length direction. The first roller group 303 is arranged between the first and second cross beams 301 and 304, and the second roller group 307 is arranged between the third and fourth cross beams 306 and 308. The rollers of the first and second roller groups 303 and 307 are rotationally connected with the two cross beams respectively. The rotating directions of the rollers of the first and second roller groups 303 and 307 are parallel to the first cross beam 301. The rollers of the first roller group 303 are driven to rotate in the same direction by the first driving assembly, and the rollers of the second roller group 307 are driven to rotate in the same direction by the second driving assembly. Vehicle position detection sensors 302 are arranged at the two ends of the top surface of each cross beam. In use, the first and second roller groups 303 and 307 are used for placing the front and rear wheels of the vehicle respectively. The width of the first and second roller groups 303 and 307 can be designed to be greater than 2.2 m, and can also be designed to be 2.3-2.7 m. The width is greater than that of the current comb tooth type carrier (less than 2 m), so that the vehicle can be parked more conveniently, the driving skill requirement is lower, and even if the vehicle is parked at an angle, the device can automatically center, and the parking experience is better.

[0041] Referring to Figure 3 The rotating mechanism 2 comprises an outer tooth type rotating disc bearing 201, a rotating driving motor (not shown) and a pinion 202. The inner ring of the outer tooth type rotating disc bearing 201 is fixed in the middle of the lifting frame 1, and the bearing frame 309 of the rotating bracket assembly 3 is fixed on the top of the outer tooth ring of the outer tooth type rotating disc bearing 201. The pinion 202 is rotationally installed on the lifting frame 1 through a bearing and is engaged with the outer tooth ring. The rotating driving motor drives the pinion 202 to rotate. In work, the rotating driving motor drives the pinion 202 to rotate, the pinion 202 drives the outer tooth ring to rotate, the outer tooth ring drives the bearing frame 309 to rotate, and then the vehicle parked on the rotating bracket assembly 3 can be driven to rotate, the direction of the vehicle is changed, and the vehicle is conveniently driven out when the vehicle is taken.

[0042] The control unit is respectively connected with the vehicle position detection sensors 302, the power unit of the first driving assembly, the power unit of the second driving assembly and the rotating driving motor.

[0043] The application is installed in the ground pit of the entrance and exit room of the stereo garage. In the initial state, referring to Figure 1, the first roller group 303 and the second roller group 307 of the rotating bracket assembly 3 are substantially flush with the ground of the access room, and the first roller group 303 and the second roller group 307 are placed forward and backward along the vehicle entering direction. After the vehicle enters, the driver can turn off the engine and get off the vehicle only by ensuring that the front and rear wheels of the vehicle are placed on the first roller group 303 and the second roller group 307, respectively. The wheel position detection sensor 302 detects the position of the wheels and transmits the detected signal to the control unit. The control unit analyzes the position state of the wheels according to the obtained signal, and then drives the rollers of the first roller group 303 or the second roller group 307 to rotate, so that the position of the wheels is adjusted to stop the vehicle in place for subsequent handling. For example, when centering, the control unit can issue a command to drive the first driving assembly where the front wheels are located to drive the rollers in the first roller group 303 to rotate in the same direction to the right, so as to drive the vehicle wheels to move to the sensing area; then drive the second driving assembly where the rear wheels are located to drive the rollers in the second roller group 307 to rotate in the same direction to the right, so as to drive the vehicle wheels to move to the sensing area, thereby adjusting and centering the vehicle. After centering is completed, the rotating driving motor drives the pinion gear 202 to rotate, the pinion gear 202 drives the outer gear ring to rotate, and the outer gear ring drives the bearing frame 309 to rotate, thereby driving the vehicle parked on the rotating bracket assembly 3 to rotate, changing the direction of the vehicle, facilitating the vehicle to drive out when the vehicle is taken, see the state in Figure 2

[0044] Therefore, by adopting the above design, the centering function is realized by cooperation of the rollers, the roller driving assembly, the vehicle detection sensor and the control unit, so that the overall structure of the handler can be greatly simplified; and the rotating function of the vehicle is realized by the rotating mechanism 2, without the need to set a large area of rotating disc, so that the structure is simpler.

[0045] In order to realize the detection of the wheel position, the present application makes the following structural improvements: the top surface of the cross beam, the top surface of the first roller group 303 and the top surface of the second roller group 307 are substantially flush; see Figure 5 The wheel position detection sensor 302 comprises a photoelectric sensor and a photoelectric protective cover, the photoelectric protective cover comprises a protruding support part 3022, the protruding support part 3022 is integrally connected with a mounting part 3021 at both ends in the length direction of the cross beam, the mounting part 3021 is fixed on the cross beam, the protruding support part 3022 is integrally connected with an inclined protective plate 3023 at both sides in parallel with the length direction of the roller, the inclined protective plate 3023 is provided with a light transmission hole 3024 for light transmission of the photoelectric sensor, and the light transmission hole 3024 is located on the side facing the roller. In this structure, the photoelectric protective cover is used to protect the photoelectric sensor from being damaged by the wheels, the photoelectric protective cover adopts a steel structure with high strength, the protruding support part 3022 forms a space for accommodating the photoelectric sensor, the slope formed by the inclined protective plate 3023 can reduce the hindering effect on the vehicle, and the light transmission hole 3024 is used for smooth transmission and reception of the photoelectric signal.​

[0046] More specifically, two groups of wheel position detection sensors 302 are respectively arranged on the first cross beam 301, the second cross beam 304, the third cross beam 306 and the fourth cross beam 308, each group of wheel position detection sensors 302 includes two wheel position detection sensors 302, the distance between the two wheel position detection sensors 302 in the group is 40-100mm, and the distance between the two groups of wheel position detection sensors 302 on the same cross beam is 2000-2200mm; the wheel position detection sensors 302 on the first cross beam 301 and the second cross beam 304 are opposite to each other, and the wheel position detection sensors 302 on the third cross beam 306 and the fourth cross beam 308 are opposite to each other. In use, the two groups of wheel position detection sensors 302 on the left of the first cross beam 301 and the second cross beam 304 can simultaneously detect the wheel signal, that is, the wheel enters the sensing area, and similarly, the two groups of wheel position detection sensors 302 on the left of the third cross beam 306 and the fourth cross beam 308 can simultaneously detect the wheel signal, that is, the wheel enters the sensing area; similarly, the two groups of wheel position detection sensors 302 on the right can simultaneously detect the wheel signal, which also indicates that the wheel enters the sensing area. When the two wheels on the left or the two wheels on the right enter the sensing area at the same time, the vehicle is centered and completed.

[0047] The elevator of the application is connected with the roller on the parking space when the wheel is transported to a certain layer parking space, and the vehicle is transmitted to the roller on the parking space through the same direction rotation of the roller. In the transmission process, in order to prevent the elevator from being unstable, the flat layer flap assembly 4 is designed.

When the rotating driving motor works to adjust the direction of the vehicle, the flat layer shaft driving part 404 rotates to drive the flat layer shaft 403 to rotate upward, thereby driving the flap 401 to flip upward and prepare, when the elevator is lifted to the target parking space, the flat layer shaft driving part 404 rotates to drive the flat layer shaft 403 to rotate downward, thereby driving the flap 401 to flip downward, the flap 401 plays a hooking role and is hung on the steel frame of the parking space, thereby keeping the elevator stable during the vehicle transfer and improving the safety of the equipment.

[0048] In the application, the structure for realizing the rotation of the first roller group 303 and the second roller group 307 to center and carry the vehicle can be preferably as follows: the structure of the first roller group 303 and the second roller group 307 is identical, and the constitution of the first driving mechanism and the second driving mechanism is identical; see Figure 4 and Figure 7 The first roller group 303 and the second roller group 307 are provided with driving rollers 3032 and driven rollers 3031, the same end of the driving rollers 3032 and the driven rollers 3031 passes through the cross beam and is provided with roller gears 3033, the roller gears 3033 in the group are connected and driven by roller chains (not shown), and the driving rollers 3032 are further provided with transmission gears 3034; the first driving mechanism and the second driving mechanism comprise roller driving motors 3037, the output shaft outer wall of the roller driving motors 3037 is fixedly provided with motor gears 3036, the transmission gears 3034 and the motor gears 3036 are connected and driven by transmission chains 3035.
