Description

TECHNICAL FIELD

[0001] The present application relates to the field of intelligent transportation and automated parking equipment, in particular to a special-shaped vertical circulating parking equipment. BACKGROUND

[0002] At present, with the continuous acceleration of urbanization, land resources are becoming increasingly scarce. Especially in old urban areas and core business areas, the problem of parking difficulty is becoming increasingly prominent. In urban planning and construction, some irregularly shaped "abnormal land plots" such as L-shaped, triangular or narrow strips are often left behind. Due to their "special-shaped" characteristics, traditional and standardized rectangular three-dimensional parking equipment cannot be directly applied, resulting in the idle and waste of valuable land resources. Therefore, developing a three-dimensional parking equipment that can efficiently utilize such special-shaped space has become a technical problem that needs to be solved in the field of urban space utilization.

[0003] In view of the above-mentioned related content, the existing vertical circulating three-dimensional garage on the market provides a solution to the problem of parking. This type of equipment usually drives the main chain through a motor, and drives a plurality of vehicle-carrying cars or trays to circulate along the fixed vertical track. In the vehicle fixing mode, a common method is to set a simple groove or shallow pit at the bottom of the carrying platform. The driver needs to use experience to accurately park the vehicle wheels in these grooves. Some devices will set fixed blocks in front and back of the platform. These designs play a basic role in preventing the vehicle from slipping forward and backward to a certain extent.

[0004] However, the above-mentioned prior art has many deficiencies in actual application. The vehicle fixing mode is too single and passive. Only relying on the wheels falling into the groove or the front and rear blocks cannot form an effective ring-shaped locking of the tires. The impact generated by the equipment at the start and stop moment, or the shaking under adverse weather such as strong wind, can easily cause the vehicle to move slightly or even shake obviously on the platform, which has serious safety hazards.

[0005] Secondly, the existing scheme has too high requirements for the operation of the driver. Whether the vehicle can be accurately parked in the specified position completely depends on the experience and technology of the person. The intervention of this human factor not only reduces the efficiency of storing and taking the vehicle, but also introduces uncontrollable risks. Once the parking deviates, the fixing effect will be greatly reduced.

[0006] More importantly, the traditional fixing method lacks active and redundant safety protection. It does not have a clamping mechanism that can actively exert and reliably self-lock after the vehicle is parked. This means that the stability of the vehicle is completely dependent on static friction and gravity. In the case of long-term operation of the equipment or unexpected power failure, it cannot guarantee that the vehicle is always firmly locked, and its reliability cannot meet the requirements of modern high-density and high-safety standard parking equipment. SUMMARY

[0007] In view of the defects of the prior art, the present application provides a special-shaped three-dimensional vertical circulation parking equipment, which solves the problems of simple and passive vehicle fixing mode, parking only relying on the experience of the driver and inability to form effective locking in the prior parking equipment.

[0014] Preferably, the plurality of side pads are made of rubber and are provided with stripes on the outer side, and the plurality of side pads abut against the outer side of the small car bottom tire.

[0015] Preferably, the inner side of the two lifting frames is symmetrically provided with a plurality of infrared detectors, and the infrared detectors are electrically connected between the transmission motor and the electric push rod.

[0016] Preferably, the transmission assembly comprises two transmission discs, the two transmission discs are fixedly connected with a connecting rod one, the outer sides of the two transmission discs are provided with transmission tooth chains, the outer sides of the transmission tooth chains are equidistantly provided with triangular mounting blocks, the inner side of the front main frame is provided with a main drive motor, and the output end of the main drive motor is fixedly connected to the inner side of one of the transmission discs.

[0018] The application provides a special-shaped three-dimensional vertical circulation parking equipment.

[0019] 1、The clamping and stabilizing assembly driven by the electric push rod clamps the tire from both sides with great force, and the wheel limiting mechanism driven by the transmission motor firmly abuts against the tire from the front and rear directions by using the self-locking characteristics of the worm and gear. The two modes work together to form multi-dimensional and redundant locking of the vehicle tire, ensure that the vehicle is always in "rigid connection" with the bearing platform during the start-stop and running of the vertical circulation, and eliminate the risk of vehicle shaking, displacement or even falling, thereby improving the safety of the equipment operation.

[0020] 2、The application integrates sensing devices such as infrared detectors, which can automatically detect whether the vehicle is parked in place.

This not only greatly improves the convenience and efficiency of users accessing the vehicle, but also effectively avoids safety hazards caused by human operation negligence or forgetfulness, making the entire parking process smoother and more reliable.

[0021] 3、The application realizes the synchronous action of multiple front and rear limiting blocks of wheels driven by one motor through the combination of "motor-gear wheel-pull rod". The classic transmission structure of "worm-worm gear-bidirectional threaded rod" is adopted at the telescopic end of the limiting block. The structure not only has stable transmission and accurate positioning, but also ensures that the limiting block will not be loosened due to the reaction force of the tire even in the state of power failure or motor stop working after abutting against the tire due to the natural self-locking characteristics of the worm and worm gear, thereby greatly enhancing the inherent reliability and fault safety of the system. The ingenious and compact mechanical design effectively reduces the complexity and potential failure points of the system, and is more conducive to long-term stable operation and maintenance.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0032] Please refer to the drawings of the present application Figure 1 - the drawings of the present application Figure 8 The present application provides a special-shaped three-dimensional vertical circulation parking equipment, which aims to realize safe and automatic parking of vehicles in limited or irregular space through an efficient transmission system and an innovative double-vehicle stabilizing system. The equipment mainly comprises a stable external support structure and a core functional assembly circulating therein. The external support structure is composed of a front main frame 1 and a rear main frame 2, which jointly build the main body of the equipment and provide a stable and reliable installation foundation and running track for the internal transmission and parking assembly.

[0033] In the inner space opposite between the front main frame 1 and the rear main frame 2, a transmission assembly 4 for driving the circulation and lifting of vehicles is arranged. The transmission assembly 4 is the power core of the entire equipment to realize vertical circulation, and a plurality of parking auxiliary mechanisms 3 are connected in series through a chain and driven to circulate along the predetermined track composed of the front main frame 1 and the rear main frame 2.

[0034] The core power source of the transmission assembly 4 is a main drive motor 401 installed inside the front main frame 1. The output shaft of the main drive motor 401 is fixedly connected to one of the two transmission discs 402 through a shaft coupling. The two transmission discs 402 are chain wheel discs, and they are rigidly fixedly connected through a high-strength connecting rod 403 to ensure that the two transmission discs 402 can rotate completely synchronously.

[0035] On the outer side of the two transmission discs 402, the transmission toothed chain 404 is installed in engagement, which is a closed chain loop that circulates on the circulating path formed by the inner guide rails of the front main frame 1 and the rear main frame 2; on the outer side of the transmission toothed chain 404, a plurality of triangular mounting blocks 405 are fixed at equal intervals according to a predetermined interval, which are the connecting bridges between the chain and the parking auxiliary mechanism 3, and the installation holes matched with the mounting rods 303 are formed in the triangular mounting blocks 405; the two ends of the mounting rod 303 on the parking auxiliary mechanism 3 are respectively inserted into the installation holes in the corresponding two triangular mounting blocks 405 on the left and right transmission toothed chains 404 and are fixed by pin shaft mode. In this way, when the main drive motor 401 starts and drives the transmission disc 402 to rotate, it can drive the transmission toothed chain 404 to move, and then drag all the parking auxiliary mechanisms 3 connected through the triangular mounting blocks 405 and the mounting rods 303 to complete the stable vertical circulating movement along the predetermined track.

[0036] The parking auxiliary mechanism 3 is the core platform unit that directly carries the vehicle to be parked, and its design fully considers the convenience and safety of vehicle parking. When the vehicle, such as a small car 7, enters the garage, it will directly drive onto the parking auxiliary mechanism 3 located on the entrance and exit layer.

[0037] In order to ensure the absolute stability of the vehicle during the entire circulating, lifting and static storage process, and prevent the vehicle from being displaced due to the shaking of the equipment starting and stopping, the application designs two sets of independent and cooperative fixing systems. The first set is the clamping and stabilizing assembly 5 located on both sides of the parking auxiliary mechanism 3, which mainly functions to clamp and fix from the left and right sides of the vehicle tires; the second set is the wheel limiting mechanism 6 installed inside the parking auxiliary mechanism 3, which mainly functions to abut and limit from the front and rear directions of the vehicle tires; the combination of the two systems forms multi-dimensional and redundant locking of the vehicle tires, thereby achieving extreme parking stability.

[0038] Reference Figure 3 - Figure 5Its main body is a solid bearing platform 301 which constitutes the basis of bearing the weight of the vehicle. On the top surface of the bearing platform 301, two tire limiting grooves 304 are symmetrically opened for the convenience of positioning the initial parking of the vehicle. When the small car 7 drives onto the platform, the tires on its left and right sides can accurately fall into the two tire limiting grooves 304, achieving preliminary lateral positioning and preventing the vehicle from being parked in a large deviation; and the bearing platform 301 can change in shape according to the terrain for the convenience of parking the vehicle and improving the utilization of space; when the car enters the garage, the traditional three-dimensional parking equipment must be 90 degrees with the garage, that is, the car and the garage must be in a straight line condition to smoothly enter the garage. The bearing platform 301 can be replaced into a rhombus structure, that is, the angle of the connecting line of the four structural columns is not 90 degrees, which can greatly improve the utilization of space and facilitate people to park.

[0039] In order to reliably connect the bearing platform 301 with the transmission assembly 4, two structurally strong lifting frames 302 are symmetrically installed on the outside of the bearing platform 301. These two lifting frames 302 not only enhance the overall rigidity of the platform, but also exist as connecting pieces. Between the two lifting frames 302, at least one mounting rod 303 is inserted and installed, and the two ends of the mounting rod 303 are connected with the chain part of the transmission assembly 4, so that the entire parking auxiliary mechanism 3 can be dragged by the transmission assembly 4 to move in a cycle.

[0040] In addition, in order to realize the high automation and intelligence of the equipment, a plurality of infrared detectors 305 are symmetrically installed on the inner side of the two lifting frames 302. The function of these infrared detectors 305 is to monitor in real time whether there is a vehicle on the bearing platform 301 and whether the vehicle is parked in the correct position. The control system can analyze the signals fed back by these detectors to determine whether to start the subsequent vehicle fixing program or lifting program, thereby avoiding the risks caused by forcibly operating due to the vehicle not being parked well, and improving the automation level and safety of the entire equipment.

[0041] Reference Figure 3 - Figure 8 The wheel limiting mechanism 6 is installed in the internal space of the bearing platform 301 for locking the wheels from the front and rear directions. Its power source is a transmission motor 601, the output end of which is fixedly connected with a transmission rod 607, and the other end of the transmission rod 607 is fixedly installed with a bevel gear one 608. In the internal space of the bearing platform 301, a connecting rod two 610 is transversely arranged, and a bevel gear two 609 is fixedly arranged at the middle part of the connecting rod two 610. The bevel gear one 608 and the bevel gear two 609 are accurately meshed together, and the transmission motor 601 outputs longitudinal rotary motion which is converted into the transverse rotary motion of the connecting rod two 610 by taking advantage of the feature of the bevel gear transmission that can change the transmission direction.

[0042] At both ends of the second connecting rod 610, a set of precision telescopic abutment components are respectively provided. Each telescopic abutment component includes a worm gear 602, which is directly fixedly connected to the corresponding end of the second connecting rod 610. Below or to the side of the worm gear 602, a bidirectional threaded rod 604 is provided. A worm wheel 603 is fixedly connected to the middle of the rod, and the worm wheel 603 meshes with the worm gear 602. On the outside of the bidirectional threaded rod 604, two sliders 605 are threadedly connected, and a limiting block 606 is firmly fixedly connected to the top of each slider 605.

[0043] When the drive motor 601 starts, it drives the bevel gear 609 and the connecting rod 610 fixed to it to rotate through the transmission rod 607 and bevel gear 608. The worm gears 602 at both ends of the connecting rod 610 rotate accordingly, driving the worm wheel 603 meshing with it to rotate. The rotation of the worm wheel 603 drives the rotation of the bidirectional threaded rod 604. Its rotation causes the two sliders 605 on it to move towards or away from each other at the same time. When they move towards each other, the limiting block 606 at the top will simultaneously press against the wheel located in the tire limiting groove 304 from both the front and rear directions, thereby achieving locking in the front and rear directions.

[0044] It is worth mentioning that the transmission combination of worm 602 and worm wheel 603 has a natural self-locking characteristic. That is, once the motor stops, the reaction force exerted by the wheel on the limit block 606 cannot drive the worm 602 to rotate in the opposite direction through the threaded rod and worm wheel 603. This ensures that the limit state can be reliably maintained even in the power-off state, which greatly enhances safety. The entire combination of worm 602, worm wheel 603, double threaded rod 604, slider 605 and limit block 606 is reasonably installed or slidably connected inside the bearing platform 301. The structure is compact and ultimately achieves a firm contact between the limit block 606 and the outer side of the car tire 7.

[0045] refer to Figure 3 - Figure 6 The clamping and stabilizing assembly 5 is responsible for clamping the tire from both the left and right sides. The core component of each assembly is a side clamp 501, on which two side pads 504 are symmetrically arranged. In order to increase friction and protect the tire surface, these side pads 504 are preferably made of rubber material with a high coefficient of friction, and their outer surface in contact with the tire has anti-slip stripes.

[0046] Two side sliders are symmetrically arranged at the bottom of the side clamp 501, and a matching side slide groove 505 is opened at the corresponding position at the top of the bearing platform 301. The side sliders are slidably connected inside the side slide groove 505. This guide rail design ensures that the side clamp 501 can only make smooth linear reciprocating motion when it moves, and will not deflect.

[0047] The driving force of this component comes from an electric push rod 503. For ease of installation, a mounting plate 502 is fixedly connected to the outside of the support platform 301, and the main body of the electric push rod 503 is installed inside the mounting plate 502. The output end of the electric push rod 503 is fixedly connected to the outside of the side clamping plate 501. When the electric push rod 503 is powered on, its output end extends or retracts, thereby directly pushing the side clamping plate 501 to clamp inward or loosen outward. Finally, multiple side pads 504 are tightly pressed against the outside of the bottom tire of the car 7, completing the lateral clamping and fixing.

[0048] Once the car 7 enters and is confirmed to be parked by the infrared detector 305, the control system issues a command to drive the electric push rod 503 of the clamping and stabilizing assembly 5 and the transmission motor 601 of the wheel limiting mechanism 6. The side clamps 501 on both sides and the front and rear limiting blocks 606 move simultaneously or sequentially, firmly locking the wheels onto the support platform 301 from four directions. Then, the main drive motor 401 starts, smoothly lifting and circulating the parking assistance mechanism 3, which has secured the vehicle, to the designated vacant parking space via the transmission assembly 4. When retrieving the car, the process is reversed; the vehicle is sent to the exit level, the lock is released, and the vehicle can be safely driven away.

[0049] Working principle: In the initial state of parking, an empty parking assist mechanism 3, driven by the transmission component 4, moves to the ground entrance level of the garage. The driver drives the car 7 onto the support platform 301 of the parking assist mechanism 3, and the left and right tires of the vehicle will naturally fall into the tire limiting grooves 304 at the top of the support platform 301. At this time, multiple infrared detectors 305 installed inside the lifting frame 302 will detect the presence of the vehicle and send a signal that the vehicle is in place to the central control system.

[0050] Upon receiving the vehicle positioning signal, the control system first activates the clamping and stabilizing assembly 5. The electric push rod 503 inside the mounting plate 502, which is fixed to the support platform 301, is energized and begins operation. Its output end pushes inward, directly acting on the outer side of the side clamp 501. Under the thrust of the electric push rod 503, the side slider at the bottom of the side clamp 501 slides within the side sliding groove 505 at the top of the support platform 301, guiding the entire side clamp 501 smoothly towards the vehicle tire. Finally, the multiple side pads 504 on the inner side of the side clamp 501 firmly abut against the left and right outer sides of the car tire 7.

[0051] Simultaneously with the lateral clamping completed, the control system activates the wheel limiting mechanism 6 installed inside the support platform 301. The drive motor 601 starts and rotates, and its output end drives the first bevel gear 608 to rotate via the transmission rod 607. Since the first bevel gear 608 meshes with the second bevel gear 609 fixed in the middle of the second connecting rod 610, the rotation of the first bevel gear 608 drives the second connecting rod 610 to rotate. Both ends of the second connecting rod 610 are fixedly connected to worm gears 602, and the rotation of the worm gears 602 drives the worm wheel 603 meshing with it to rotate. The worm wheel 603 is fixedly connected to the double-threaded rod 604, so the rotation of the worm wheel 603 is ultimately converted into the rotation of the double-threaded rod 604. As the double-threaded rod 604 rotates, the two sliders 605 threaded to its outside move towards each other simultaneously, causing the limiting block 606 fixed on the top of the slider 605 to abut and lock the tire from both front and rear directions, completing the second layer of front and rear direction limiting and fixing.

[0052] Once the control system confirms that the clamping stabilizing component 5 and the wheel limiting mechanism 6 have locked the vehicle, it activates the main drive motor 401 installed inside the front main frame 1. The output shaft of the main drive motor 401 drives one transmission disc 402 to rotate, and through a rigid connection with connecting rod 403, drives the other transmission disc 402 to rotate synchronously. The rotation of the two transmission discs 402 drives the meshing transmission chain 404 to circulate along a closed path formed by the inner guide rails of the front main frame 1 and the rear main frame 2. Since the parking assist mechanism 3 is connected to the transmission chain 404 through the mounting rod 303 and the triangular mounting block 405, the entire parking assist mechanism 3, which carries and secures the car 7, is smoothly lifted and circulated to the designated empty parking space for storage as the chain moves.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
