Description

Technical Field

[0001] This solution belongs to the technical field of mechanical garages, and specifically relates to a three-dimensional garage. Background Art

[0002] Three-dimensional garages, also known as multi-story parking lots or mechanical parking garages, can trace their concept back to the early 20th century and gradually developed with the advancement of the industrial revolution and the rise of the automotive industry. Initially, the design of three-dimensional garages was relatively simple, mostly manual or semi-automatic operation, with limited space utilization and complex operation. Entering the 21st century, with the rapid development of automation technology, computer technology, and materials science, the technology of three-dimensional garages has achieved a qualitative leap, and intelligence, automation, and large-scale have become the mainstream trends.

[0003] Currently, there are various types of three-dimensional garages on the market, including but not limited to lifting and traversing type, vertical circulation type, plane moving type, roadway stacking type, etc. These different types of three-dimensional garages have their own advantages and disadvantages, but the common goal is to maximize space utilization, improve parking efficiency, and strive to reduce operating costs and maintenance difficulties.

[0004] With the continuous growth of the car ownership, especially in the central areas of large cities, the problem of parking difficulty has become increasingly severe. Three-dimensional garages, with their unique space utilization advantages, have become an important way to relieve parking pressure. However, in the face of the growing market demand, the technology of three-dimensional garages also faces many challenges, among which the most prominent is the balance problem between safety and convenience.

[0005] In a three-dimensional garage, as the main component for carrying vehicles, the lifting movement of the car carrier plate is achieved through a series of precise mechanical structures. Among them, the lifting chain, as a key transmission component, is responsible for vertically moving the car carrier plate and the vehicle to the designated level. However, since the design of the entrance and exit of the car carrier plate often matches the body width of the vehicle to maximize space utilization on the premise of ensuring the smooth entry and exit of the vehicle, this to a certain extent limits the space on both sides of the car carrier plate. When a vehicle enters and exits a three-dimensional garage, if the driver operates improperly or the vehicle size is close to the design limit, it is possible for the vehicle to rub against the lifting chain.

[0006] Such rubbing incidents will not only cause damage to the vehicle surface, affecting its appearance and service life, but may also cause wear or breakage of the lifting chain, thereby affecting the stability and safety of the entire three-dimensional garage. In addition, frequent rubbing will also increase maintenance costs, reduce the user experience, and pose a certain obstacle to the popularization and application of three-dimensional garages. Utility Model Content

[0007] This solution aims to overcome at least one defect in the prior art and provides a three-dimensional garage for solving the problem that the vehicle is prone to rubbing against the lifting chain when entering and exiting the garage.

[0008] To solve the above technical problems, the following technical solutions are adopted:

[0009] A three-dimensional garage, which includes a car-carrying board, a transmission mechanism, and a driving mechanism. The transmission mechanism includes a flexible transmission member and a rotating member. One end of the flexible transmission member is connected to the rotating member, and the other end is connected to the car-carrying board. The rotating member retracts or releases the flexible transmission member under the drive of the driving mechanism to raise or lower the car-carrying board. Particularly, the three-dimensional garage further includes a locking mechanism, which includes a fixed seat fixedly connected to the side of the car-carrying board and a bolt slidably connected to the fixed seat; a first connecting member is provided on the side of the car-carrying board, and the first connecting member is provided with a first through hole; an end of the flexible transmission member is connected with a second connecting member, and the second connecting member is provided with a second through hole; the first through hole, the second through hole, and the bolt are coaxial when the flexible transmission member is released in place, and the bolt slides axially to withdraw from or insert into the second through hole and the first through hole, so as to release or restore the connection between the flexible transmission member and the car-carrying board.

[0010] This solution enables the three-dimensional garage to disconnect the flexible transmission member from the car-carrying board and retract the flexible transmission member before the vehicle drives onto or off the car-carrying board by adding a locking mechanism, making the space above and around the car-carrying board more open, so that the vehicle can drive onto or off the car-carrying board as if on flat ground. After the vehicle safely enters and exits, the flexible transmission member is reconnected to the car-carrying board and the lifting is started. Fundamentally, it avoids the possibility of direct contact between the flexible transmission member and the vehicle, thus greatly improving the safety during vehicle parking. This method avoids potential conflicts between the transmission member and the vehicle by precisely controlling the timing of retracting and releasing the flexible transmission member, reduces delays and maintenance requirements caused by rubbing, improves the operation efficiency of the garage, enables users to enjoy a faster and smoother parking experience, and enhances the attractiveness and market competitiveness of the three-dimensional garage. Since it avoids wear or accidental damage caused by rubbing, this solution significantly extends the service life of the flexible transmission member, reduces the frequency of replacement due to wear or accidental damage, and also reduces the maintenance burden and cost of the overall structure of the garage, which not only reduces the economic expenditure of the garage operator, but also improves the long-term stability and reliability of the garage equipment.

[0011] The locking mechanism is also configured with a driving component to provide a power source for the sliding of the bolt, so as to electrically release or restore the connection between the flexible transmission member and the car-carrying board. The driving component can adopt a cylinder, the piston rod of the cylinder is connected to the bolt, and the bolt slides under the drive of the piston rod, withdrawing from or inserting into the first through hole and the second through hole, so as to realize the release or restoration of the connection between the flexible transmission member and the car-carrying board. The driving component can also adopt a motor, the motor can be connected to the bolt through a transmission component, the transmission component is in transmission connection with the bolt, the driving component is in transmission connection with the transmission component, and the transmission component drives the bolt to slide under the drive of the driving component, withdrawing from or inserting into the first through hole and the second through hole, so as to realize the release or restoration of the connection between the flexible transmission member and the car-carrying board.

[0012] The transmission assembly can be a ball screw mechanism, including a screw and a nut that are threadedly engaged with each other. The screw is connected to the output shaft of the motor, and the bolt is slidably connected to the fixed seat through the nut. The transmission assembly can also be a gear and rack mechanism, including a gear and a rack that are meshed with each other. The gear is connected to the output shaft of the motor, and the rack is connected to the bolt. The transmission assembly can also be a worm and worm gear mechanism, including a worm and a worm gear that are meshed with each other. The worm is connected to the output shaft of the motor, and the worm gear is connected to the bolt.

[0013] The stereoscopic garage is provided with a set of locking mechanisms and two sets of spaced-apart transmission mechanisms on the same side of the car-carrying plate. The locking mechanism is located between the two sets of transmission mechanisms. Its driving assembly uses a motor, and the transmission assembly uses a ball screw mechanism. The locking mechanism is provided with two fixed seats, two bolts, two nuts, a lead screw, and a motor. The output shaft of the motor is drivingly connected to the middle of the lead screw. Opposite-threaded portions are provided at both ends of the lead screw and are respectively engaged with the two nuts. The two bolts are respectively slidably connected to the two fixed seats through the two nuts. When the lead screw is driven by the motor to drive the nuts at both ends to slide, the two bolts are simultaneously withdrawn from or inserted into the first through hole and the second through hole, achieving the effect of unlocking and locking two chains, which can improve the efficiency of releasing or restoring the connection between the flexible transmission member and the car-carrying plate.

[0014] The first connecting member can be provided with two coaxially arranged and spaced-apart first through holes. When the flexible transmission member is released in place, the second through hole is located between the two first through holes. After the bolt is inserted into the first through hole and the second through hole, the second connecting member is completely restricted by the first connecting member and the bolt, ensuring the connection stability between the flexible transmission member and the car-carrying plate. The first connecting member can also be provided with a first through hole. The first through hole, the second through hole, and the fixed seat are arranged in sequence when the flexible transmission member is released in place. After the bolt is inserted into the first through hole and the second through hole, the second connecting member is completely restricted by the first connecting member and the bolt, and can also ensure the connection stability between the flexible transmission member and the car-carrying plate.

[0015] The second connecting member can be designed as a long strip structure, with one end connected to the flexible transmission member and the other end provided with a second through hole. The long strip-shaped second connecting member has a certain guiding effect, which can further reduce the possibility of accumulation, ensure that the second through hole can be smoothly aligned with the first through hole, and facilitate the insertion of the bolt. The end of the second connecting member provided with the second through hole can be provided with a tip, which can better guide the second connecting member to be inserted between the first through hole and the guiding structure, and further reduce the possibility of accumulation.

[0016] The present solution has the following beneficial effects compared with the prior art: By adding a locking mechanism, the three-dimensional garage can disconnect the flexible transmission member from the car carrier plate and retract the flexible transmission member before the vehicle enters or exits the car carrier plate, making the space above and around the car carrier plate more open. This allows the vehicle to enter or exit the car carrier plate as smoothly as on flat ground. After the vehicle safely enters and exits, the flexible transmission member is reconnected to the car carrier plate and lifting is started. This effectively solves the problem that the vehicle is prone to rubbing against the flexible transmission member in the three-dimensional garage, not only improving safety, efficiency, and user experience, but also enhancing the durability of the equipment, reducing maintenance costs, and improving space utilization, providing strong technical support for the future development of three-dimensional garages.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] To enable those skilled in the art to better understand the present solution, the following further details the present solution with reference to specific embodiments.

[0026] Figures 1 to 3Schematically shows a possible multi - storey parking garage for parking vehicles, enabling two or more vehicles to be parked in a space where originally only one vehicle could be parked on the ground. The multi - storey parking garage includes a car - carrying plate 100, a transmission mechanism 200, and a driving mechanism 300.

[0027] The car - carrying plate 100, as a platform directly bearing the vehicle, taking into account bearing strength, stability, and safety, can be made of high - strength steel or aluminum alloy materials, and its surface is covered with anti - slip and wear - resistant materials to ensure that the vehicle is parked stably and is easy to get on and off under different weather conditions. A safety guardrail or enclosure is provided at the edge of the car - carrying plate 100 to prevent the vehicle from accidentally slipping. At the same time, a reinforcing rib structure can be provided below the car - carrying plate 100 to enhance the overall load - bearing capacity. In addition, to facilitate vehicle positioning, a parking space indicator light or a laser positioning device can be integrated on the car - carrying plate 100 to guide the driver to park accurately.

[0028] The transmission mechanism 200 is the key to realizing the vertical movement of the car - carrying plate 100. Its structure includes a flexible transmission member 210 and a rotating member 212. One end of the flexible transmission member 210 is connected to the rotating member 212, and the other end is connected to the car - carrying plate 100. The flexible transmission member 210 can be a chain, and the rotating member 212 can correspondingly be a sprocket; the sprocket is usually made of metal materials (such as steel), has high strength and wear resistance, and its structure includes a wheel body, a hub, teeth, etc. The wheel body is the main part of the sprocket, its shape is disc - shaped, the hub is located at the center of the wheel body for installing and fixing the sprocket, and the teeth are the parts on the sprocket that mesh with the chain. The chain is composed of many chain links, and each chain link is connected by a pin. The chain link is usually made of metal materials, and there are grooves on the chain link for anchoring the teeth on the sprocket. Through the meshing of the teeth and the grooves, the power and rotational movement of the sprocket can be transmitted to the chain, thereby driving the car - carrying plate 100 to rise or fall. The flexible transmission member 210 can also be a high - strength steel wire rope, a synthetic fiber rope and other ropes. These materials have excellent tensile strength and wear resistance, can bear the weight of the vehicle and the car - carrying plate 100 and achieve long - distance trouble - free transmission; correspondingly, the rotating member 212 can be a winder, and the winder internally integrates a precision reduction device and a braking system to ensure a smooth and controllable transmission process. The reduction device can effectively reduce the motor speed and increase the torque output, making the lifting and lowering of the car - carrying plate 100 more stable, while the braking system can quickly lock the winder in case of power failure or emergency to prevent the car - carrying plate 100 from accidentally falling and ensuring vehicle safety.

[0029] The driving mechanism 300 provides a power source for the lifting of the vehicle-carrying plate 100, and is usually composed of a motor, a controller and a power supply system. The motor is connected to the rotating member 212 as a power output device, and the rotating member 212 retracts or releases the flexible transmission member 210 under its drive to make the vehicle-carrying plate 100 rise or fall. The motor needs to have sufficient power and torque to meet the total weight requirements of the vehicle-carrying plate 100 and the vehicle. Specifically, a DC brushless motor or a servo motor can be used, which has the advantages of high efficiency, low noise, and easy maintenance. The controller is responsible for receiving external instructions (such as remote controls, touch screens, etc.) and converting them into electrical signals that can be recognized by the motor, controlling the forward and reverse rotation and speed of the motor, and realizing the precise lifting and lowering of the vehicle-carrying plate 100. The controller can also have safety functions such as overload protection and short circuit protection to ensure stable operation of the system. The power supply system provides a stable and reliable power supply for the motor and the controller, usually including mains access, transformers, voltage stabilizers and backup power supplies (such as batteries), etc., to ensure that a certain operating time can be maintained in the event of a sudden power outage, so as to safely evacuate the vehicle.

[0030] like Figure 2 As shown, the transmission mechanism 200 is usually symmetrically arranged on the left and right sides of the vehicle loading plate 100, and the front side of the vehicle loading plate 100 serves as an entrance and exit for vehicles to enter or leave. In order to maximize space utilization, the width of the vehicle loading plate 100 is often matched with the width of the vehicle body, and the width of the entrance and exit is determined by the width of the vehicle loading plate 100, which limits the space for vehicles to enter and exit the vehicle loading plate 100 to a certain extent. When a vehicle enters and exits the stereo garage, if the driver operates improperly or the vehicle size is close to the design limit, the vehicle may be scratched against the flexible transmission member 210. In order to avoid scratches between the vehicle and the flexible transmission member 210, the stereo garage is also equipped with a locking mechanism 400 to release or restore the connection between the flexible transmission member 210 and the vehicle loading plate 100.

[0031] like Figures 4 to 5As shown, the locking mechanism 400 includes a fixed seat 410 and a latch 420. The fixed seat 410 is fixedly connected to the side of the car-carrying board 100, and the latch 420 is slidably connected to the fixed seat 410. A first connecting member 110 is provided on the side of the car-carrying board 100. The first connecting member 110 is provided with a first through hole 111 for connecting the flexible transmission member 210 through the latch 420. An end of the flexible transmission member 210 is connected with a second connecting member 211. The second connecting member 211 is provided with a second through hole for connecting the car-carrying board 100 through the latch 420. The first through hole 111, the second through hole and the latch 420 are substantially coaxial when the flexible transmission member 210 is released in place (subject to the smooth extraction or insertion of the latch 420). The latch 420 slides axially to extract or insert into the second through hole and the first through hole 111, thereby releasing or restoring the connection between the flexible transmission member 210 and the car-carrying board 100. Among them, "the flexible transmission member 210 is released in place" means that the flexible transmission member 210 is released until it is aligned with the car-carrying board 100, that is, the flexible transmission member 210 is released until the first through hole 111 and the second through hole are substantially coaxial.

[0032] Thus, the multi-story garage can operate according to the Figure 6 shown process. Before the vehicle drives into or out of the car-carrying board 100, first release the connection between the flexible transmission member 210 and the car-carrying board 100 and retract the flexible transmission member 210, as Figure 3 shown, to make the space above and around the car-carrying board 100 more open, so that the vehicle can drive into or out of the car-carrying board 100 as if on flat ground. After the vehicle safely enters and exits, reconnect the flexible transmission member 210 and the car-carrying board 100 and start lifting. This process design fundamentally avoids the possibility of direct contact between the flexible transmission member 210 and the vehicle, thus greatly improving the safety during vehicle parking. This method avoids potential conflicts between the transmission member and the vehicle by precisely controlling the timing of retracting and releasing the flexible transmission member 210, reduces delays and maintenance requirements caused by scratching, improves the operation efficiency of the garage, enables users to enjoy a faster and smoother parking experience, and enhances the attractiveness and market competitiveness of the multi-story garage. Since it avoids wear or accidental damage caused by scratching, this solution significantly extends the service life of the flexible transmission member 210, reduces the frequency of replacement due to wear or accidental damage, and also reduces the maintenance burden and cost of the overall structure of the garage. This not only reduces the economic expenditure of the garage operator, but also improves the long-term stability and reliability of the garage equipment.

[0033] To electrically release or restore the connection between the flexible transmission member 210 and the car carrier plate 100, the locking mechanism 400 can be an electric bolt 420. That is, the locking mechanism 400 is also configured with a driving component to provide a power source for the sliding of the bolt 420. The driving component can use a cylinder or a motor. For the former, the piston rod of the cylinder is connected to the bolt 420, and the bolt 420 slides under the drive of the piston rod, withdrawing from or inserting into the first through hole 111 and the second through hole, thereby realizing the release or restoration of the connection between the flexible transmission member 210 and the car carrier plate 100. For the latter, the locking mechanism 400 is also configured with a transmission component. The transmission component is in transmission connection with the bolt 420, and the driving component is in transmission connection with the transmission component. The transmission component drives the bolt 420 to slide under the drive of the driving component. The transmission component can be a ball screw mechanism, including a screw rod and a nut that are in threaded cooperation with each other. The screw rod is connected to the output shaft of the motor, and the bolt 420 is slidably connected to the fixed seat 410 through the nut; it can also be a gear rack mechanism, including a gear and a rack that are in meshing with each other. The gear is connected to the output shaft of the motor, and the rack is connected to the bolt 420; it can also be a worm and worm gear mechanism, including a worm and a worm gear that are in meshing with each other. The worm is connected to the output shaft of the motor, and the worm gear is connected to the bolt 420.

[0034] For balance considerations, often two sets or even more sets of transmission mechanisms 200, one in front and one behind, are installed on the same side of the car carrier plate 100. For the case where two sets of transmission mechanisms 200 are installed on the same side of the car carrier plate 100, the driving component uses a motor, and the transmission component uses a ball screw mechanism, the locking mechanism 400 can be arranged in the middle of the two sets of transmission mechanisms 200, and is provided with two fixed seats 410, two bolts 420, two nuts, one screw rod, and one motor. The output shaft of the motor is in transmission connection with the middle part of the screw rod. The two ends of the screw rod are respectively provided with threads in opposite directions, which are respectively matched with the two nuts. The two bolts 420 are respectively slidably connected to the two fixed seats 410 through the two nuts. When the screw rod is driven by the motor to drive the nuts at both ends to slide, the two bolts 420 are simultaneously withdrawn from or inserted into the first through hole 111 and the second through hole. One bolt 420 withdraws from or inserts into the first through hole 111 and the second through hole in the front, and the other bolt 420 withdraws from or inserts into the first through hole 111 and the second through hole in the rear, achieving the effect of unlocking two chains simultaneously, which can improve the efficiency of releasing or restoring the connection between the flexible transmission member 210 and the car carrier plate 100.

[0035] The driving assembly can also be configured with a controller, which is responsible for receiving external instructions (such as from a remote control, a touch screen, a sensor, etc.) and converting them into electrical signals recognizable by the motor or the cylinder, controlling the forward and reverse rotation and the speed of the motor or the telescopic movement of the piston rod of the cylinder, so as to unlock or relock the locking mechanism 400. The external instructions can be manually triggered by a person through a remote control, a touch screen, etc., or automatically triggered by a sensor. The sensor is responsible for detecting the in-place conditions of the flexible transmission member 210, the car carrier plate 100, the vehicle, etc. and sending an unlocking or relocking instruction to the controller, and the controller controls the motor or the cylinder according to this instruction, so as to automatically release or restore the connection between the flexible transmission member 210 and the car carrier plate 100.

[0036] Both the first connecting member 110 and the locking mechanism 400 are arranged on the car carrier plate 100, and their positional relationship is restricted by the car carrier plate 100. It is impossible for the first connecting member 110 to disengage from the bolt 420, while the second connecting member 211 is connected to the flexible transmission member 210 and is prone to disengaging from the bolt 420. For this reason, two coaxially arranged and spaced-apart first through holes 111 can be provided on the first connecting member 110, and the accommodating space between the two first through holes 111 is for the second connecting member 211 to be inserted. When the flexible transmission member 210 is released in place, the second through hole is located between the two first through holes 111. After the bolt 420 is inserted into the first through hole 111 and the second through hole, the second connecting member 211 is completely restricted by the first connecting member 110 and the bolt 420, ensuring the connection stability between the flexible transmission member 210 and the car carrier plate 100. In addition, the first through hole 111, the second through hole and the fixing seat 410 can be arranged in sequence when the flexible transmission member 210 is released in place, restricting the second connecting member 211 between the first connecting member 110 and the fixing seat 410, and the connection stability between the flexible transmission member 210 and the car carrier plate 100 can also be ensured.

[0037] After the flexible transmission member 210 is disengaged from the vehicle carrier plate 100 and retracted, due to the lack of the gravity of the vehicle carrier plate 100 and the flexibility of the flexible transmission member 210 itself, during the process of being re-released, its end is likely to accumulate on the vehicle carrier plate 100 or the first connecting member 110, especially when the first connecting member 110 is provided with two first through holes 111 and the accommodation space between them is relatively small. After connecting the second connecting member 211, the gravity of the second connecting member 211 can reduce the possibility of accumulation to a certain extent. The second connecting member 211 can be designed into a long strip structure, with one end connected to the flexible transmission member 210 and the other end provided with the second through hole. The long strip-shaped second connecting member 211 has a certain guiding effect, which can further reduce the possibility of accumulation, ensure that the second through hole and the first through hole 111 can be smoothly aligned, and facilitate the insertion of the pin 420. The end of the second connecting member 211 provided with the second through hole can be set as a tip, which can better guide the second connecting member 211 to be inserted between the two first through holes 111 or between the first connecting member 110 and the fixed seat 410, and further reduce the possibility of accumulation.

[0038] Obviously, the above embodiments of this solution are only examples for clearly explaining this solution, rather than limitations on the implementation manners of this solution. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of this solution shall be included in the protection scope of the claims of this solution.
