Description

TECHNICAL FIELD

The present disclosure relates to the field of parking equipment, and in particular to a three-dimensional parking system.

BACKGROUND ART

At present, the number of motor vehicles in China has reached 372 million, and still maintains a growth trend. Correspondingly, a vacancy of parking places is also increasing. Traditional parking lots are mostly constructed on the ground or underground, utilization of ground parking space is low, an investment of underground parking garage is high, and there are risks of flood and waterlogging. Meanwhile, the existing parking lot not only has poor experience and low flexibility, but also takes up to 10 minutes to find a parking place and has low degree of intelligence, which greatly increases difficulty of car owners when parking. In view of this, in order to alleviate the issue of parking difficulty, three-dimensional parking equipment has been developed.

In China, the three-dimensional parking industry mainly includes three-dimensional parking buildings and independent three-dimensional parking equipment. The construction of the three-dimensional parking buildings occupies a large amount of urban land. In many cases, the utilization rate of these facilities is yet very low (about 20%-30%), which is mainly caused by a long distance and a slow process of entry and exit. An existing available solution on the market is a vertical cycle parking system. The existing vertical cycle parking system has been optimized to some extent in terms of space utilization rate, three-dimensional structure arrangement, intelligent parking operation, etc., but the turnover and transportation of vehicles will be involved in a process of parking or picking up because the three-dimensional parking equipment is mostly provided with multi-layer parking space in a height space, while the existing parking equipment pays no attention to safety issues in the process of turnover and transportation of vehicles, so the potential safety hazards of the vertical cycle parking system are increased.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Technical solutions in embodiments of the present disclosure will be clearly and completely described below with reference to the drawings showing the embodiments of the present disclosure. The described embodiments are merely part rather than all of the embodiments of the present disclosure. On the basis of the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without undue experimentation fall within the scope of the present disclosure.

One of the objectives of the present disclosure is to provide a three-dimensional parking system, which has reasonable structure arrangement and strong safety in use, and can effectively address the issue of potential safety hazards in the process of turnover and transportation of vehicles in existing parking equipment.

In order to make the abovementioned objective, features, and advantages of the present disclosure more apparent and comprehensible, the present disclosure is further described in detail below with reference to the drawings and the embodiments.

Embodiment 1

As shown in FIG. 1 to FIG. 11, the present embodiment provides a three-dimensional parking system 100, which mainly includes a supporting upright column 1, an annular railway 2, a parking platform 3, a platform bracket 4, a transportation module 8, a vertical power system 5, a rotating power system 6, and a platform interlocking system. A longitudinal channel 7 extending in an axial direction of the supporting upright column 1 is arranged on the supporting upright column 1. The transportation module 8 is arranged in the longitudinal channel 7. The vertical power system 5 is used for driving the transportation module 8 to reciprocate up and down along the longitudinal channel 7. The annular railway 2 is arranged around a periphery of the supporting upright column 1. At least one layer of the annular railway 2 is arranged in the axial direction of the supporting upright column 1 in a spaced manner. A notch 9 is formed in a position of each layer of annular railway 2 penetrated by the longitudinal channel 7. When the transportation module 8 moves to the notch 9 of any layer, the transportation module 8 can form a closed circular ring railway with the annular railway 2 of the current or correspondingly layer. The platform bracket 4 is movably arranged on the transportation module 8 and each layer of the annular railway 2. Each of the platform brackets 4 is provided with a parking platform 3 for loading a vehicle to be parked thereon. The rotating power system 6 is used for driving the corresponding platform bracket 4 to move on the closed circular ring railway formed above, so as to realize position displacement of the platform bracket 4 between the transportation module 8 and the annular railway 2 of the current layer, thereby implementing parking or picking up of the vehicle. The platform interlocking system includes a pushing mechanism and a locking mechanism 10. Each locking mechanism 10 is arranged at a position of each layer of annular railway 2 close to the notch. The locking mechanism 10 on the annular railway 2 where the transportation module 8 does not stay (that is, the notch of the annular railway 2 is in an open state) is in a locked position, so as to lock the platform bracket 4 on the annular railway 2 of the current layer, thereby preventing the platform bracket 4 from moving freely on the annular railway 2 of the current layer. Each platform bracket 4 is configured with the pushing mechanism. When the transportation module 8 moves to the notch 9 of any layer and forms the closed circular ring railway (that is, the notch of the annular railway 2 is closed by the transportation module 8), the pushing mechanism drives the platform bracket 4 on the transportation module 8 to be in a force application position, so as to trigger the locking mechanism 10 and enable the locking mechanism 10 to unlock the platform bracket 4 on the annular railway 2 of the current layer, thereby realizing the position displacement of the platform bracket 4 between the transportation module 8 and the annular railway 2 of the current layer.

In the present embodiment, the three-dimensional parking system further includes a control system. The control system is in communication connection with at least one of the vertical power system 5, the rotating power system 6, and the platform interlocking system mentioned above. As a preference, the control system is in communication connection with each of the vertical power system 5, the rotating power system 6, and the platform interlocking system mentioned above, in order to control the operation of the overall three-dimensional parking system 100.

In the present embodiment, each layer of the locking mechanism 10 includes a locking rod and a return spring. A middle part of the locking rod is hinged to the annular railway 2. One end of the locking rod is provided with a boss which can prevent the platform bracket 4 from moving along the annular railway 2, and the other end thereof is provided with an unlocking part which can be used for being pressed in a contact manner by the platform bracket 4 on the transportation module 8. The return spring is arranged between the locking rod and the annular railway 2, and can maintain a locking state of the boss to the platform bracket 4. And after the unlocking part is pressed in a contact manner by the platform bracket 4, the locking state is released (that is, after the locking rod overcomes an elastic force of the spring, the boss is moved to an unlocked position where the platform bracket is not prevented from moving along the annular railway). As a preference, the abovementioned boss is provided with a bump or a clamping groove, so as to specifically implement a locking behavior. For example, the bump or the clamping groove is snap-fitted into the rotating power system 6 of the current layer to prevent normal operation of the rotating power system 6 of the current layer, so as to achieve locking the platform bracket 4 on the annular railway 2 of the current layer, and thereby prevent the platform bracket 4 from moving or offsetting on the annular railway 2, which is beneficial to reducing the risk of the vehicle falling and improving the safety of the vehicle staying in the air.

In the present embodiment, the locking mechanisms 10 each are provided with a locking mechanism base. The middle part of the locking rod is hinged to the locking mechanism base. The return spring is arranged between the locking rod and the locking mechanism base. The locking mechanism base is fixedly mounted at a position of the annular railway 2 close to the notch by bolts, so that the locking mechanism 10 can be triggered in time when the transportation module 8 complements the notch of the current layer, thereby releasing the limitation to the rotation of the platform bracket 4 on the current layer.

In the present embodiment, each layer of the locking mechanism 10 of is provided with a state sensor. The state sensor is in communication connection with the control system of the three-dimensional parking system 100 to monitor working state of the locking mechanism 10 in real time, that is, to monitor whether the locking mechanism 10 is in a locked state or an unlocked state, and to transmit real-time state information to the control system.

In the present embodiment, each layer of the annular railway 2 includes an upper annular rail and a lower annular rail 21 located below the upper annular rail. The notch 9 is formed at each of the positions of the upper annular rail and the lower annular rail 21 through which the longitudinal channel 7 penetrates. Correspondingly, the transportation module 8 includes an upper annular rail for complementing notch 82 and a lower support block 81. The upper annular rail for complementing notch 82 is used for butting with upper annular rail of any layer to form an upper closed circular ring rail. A top of the platform bracket 4 is hinged slidably to the upper annular rail for complementing notch 82 and the upper annular rail of any layer. The lower support block 81 is used for butting with lower annular rail 21 of any layer to form a lower closed circular ring rail. The upper closed circular ring rail and the lower closed circular ring rail form a closed circular ring railway together. In this way, each set of closed circular ring railway has a double-layer structure. In the present embodiment, the lower support block 81 can be used for installing the pushing mechanism and/or the rotating power system 6. In an actual operation, the locking mechanism base is fixedly mounted at a position on an upper surface of the lower annular rail 21 close to the notch by bolts.

In the present embodiment, as a preference, in order to save axial space of the supporting upright column 1, any two adjacent annular railways 2 share a common annular rail structure. For example, the upper annular rail of the lowest annular railway 2 and the lower annular rail of the penultimate layer of annular railway 2 are combined into one, and the upper part can serve as a lower annular rail of an upper layer, and the lower part can serve as an upper annular rail of a lower layer. In an actual operation, in order to avoid the overall stability imbalance caused by the parking system being too high, it is preferred to arrange four layers (sets) of annular railways 2 uniformly spaced in the axial direction of the supporting upright column 1. Meanwhile, two to four platform brackets 4 are simultaneously fitted on the annular railway 2 where the transportation module 8 does not stay. The transportation module 8 is provided with a platform bracket 4 all the time. On the closed circular railway, three to five platform brackets 4 can be realized to operate simultaneously. As a preference, in the present embodiment, two platform brackets 4 are simultaneously fitted on the annular railway 2 where the transportation module 8 does not stay. The transportation module 8 is provided with a platform bracket 4 all the time. And three platform brackets 4 can be realized to operate simultaneously on the formed closed circular ring railway of each layer.

More specifically, on the basis of the structure that three platform brackets 4 can be realized to operate simultaneously on the closed circular ring railway, each of the upper annular rail and the lower annular rail 21 is set as a ⅔ circular ring structure (corresponding to a central angle of 240°), and the upper annular rail for complementing notch 82 and the lower support block 81 are respectively ⅓ circular ring structures (corresponding to a central angle of 120°). Four layers of annular railways 2 are adopted, each layer of annular railway 2 is provided with two platform brackets 4 and the transportation module 8 is always provided with a platform bracket 4, such that there are nine parking places in the system in total, thereby realizing efficient utilization of space.

In the present embodiment, taking an installation structure of the platform brackets 4 on the upper annular rail for complementing notch 82 as an example, the foregoing “hinged slidably” refers to that the top of the platform bracket 4 can slide along the upper annular rail for complementing notch 82, and can also rotate relative to the upper annular rail for complementing notch 82. In an actual operation, the following way can be adopted. The top of any platform bracket 4 can be mounted slidably on the upper annular rail for complementing notch 82 or a corresponding layer of upper annular rail through a slider. The top of the platform bracket 4 is hinged to the slider through a hinge or a pin shaft. Each slider is an annular slider. When the closed circular ring railway is formed, the annular sliders on all the platform brackets 4 of the current layer are sequentially butted end to end to form a closed circular ring slider. As a preference of the present embodiment, each annular slider is set as a ⅓ annular structure (corresponding to a central angle of 120°). Of course, in case that more than three platform brackets 4 are arranged on the closed circular ring railway, the corresponding center angles of the annular sliders, the upper annular rails, the lower annular rails 21, the upper annular rail for complementing notch 82, and lower support blocks 81 can be adjusted adaptively.

In the present embodiment, a guide wheel block 11 which can be fitted with the lower closed circular ring rail is arranged at a bottom or a middle part of each platform bracket 4. The guide wheel block 11 includes a guide wheel. As a preference, each set of the guide wheel blocks 11 includes a side wheel, a longitudinal wheel, and a wheel bracket. Both the side wheel and the longitudinal wheel are mounted on the wheel bracket. The wheel bracket is fixed to the platform bracket 4, and is formed at least at the closed circular ring railway. When the rotating power system 6 drives the platform bracket 4 on the current layer to rotate, both the side wheel and the longitudinal wheel can be in sliding fit with the lower annular rail 21 of the current layer. The longitudinal wheel is fitted with an upper surface of the lower annular rail 21, and an axis of the longitudinal wheel is set perpendicular to the supporting upright column 1. The side wheel is fitted with an outer side surface of the lower annular rail 21, and an axis of the side wheel is set parallel to the supporting upright column 1. Two sets of the abovementioned guide wheel blocks 11 are preferably arranged on any platform bracket 4.

In the present embodiment, as shown in FIG. 3 to FIG. 5, the rotating power system 6 includes annular ring gears 61, a driving gear 62, and a rotation driving mechanism 63. The annular ring gears 61 are fixedly mounted on the platform bracket 4. When the closed circular ring railway is formed, the annular ring gears 61 on all the platform brackets 4 of the current layer are sequentially butted end to end to form a closed circular ring gear. The driving gear 62 is arranged on the lower support block 81 or the lower annular rail 21 and is engaged with the closed circular ring gear, so as to drive the platform bracket 4 to perform the position displacement between the transportation module 8 and the annular railway 2 on the current layer. The rotation driving mechanism 63 is connected to the driving gear 62, so as to drive the driving gear 62 to rotate. The rotation driving mechanism 63 may be a driving electric motor, a driving motor, a mechanical transmission mechanism including a gear transmission mechanism, or the like. The rotation driving mechanism 63 can be fixed to the lower annular rail 21 or the lower support block 81 of the transportation module 8, and itself should have a locking or locking-up structure to further improve the locking effect of the rotating power system 6 on the platform bracket 4 during lifting and lowering of the transportation module 8. For example, when the rotation driving mechanism 63 adopts a driving motor, a motor shaft locking device may be arranged in the motor to realize such a locking function.

In the present embodiment, it is preferred that the driving gear 62 is located at an inner ring of the annular ring gear 61, so as to form an internal engagement gear assembly therebetween. In an actual operation, an external engagement form can also be adopted between the driving gear 62 and the annular ring gear 61, that is, the driving gear 62 is located on outside of the annular ring gear 61. In this case, one driving gear 62 can be provided, or one driving gear 62 can be arranged on each platform bracket 4. A specific arrangement form of the rotating power system 6 cannot be limited to the abovementioned forms of internal and external gear engagement, but can also be a gear engagement set containing multiple gears or other structures including a worm and worm wheel driving form, depending on an actual situation.

In the present embodiment, the pushing mechanism includes at least one pushing hydraulic cylinder 12. The pushing hydraulic cylinder 12 includes a cylinder body and a cylinder rod. One of the cylinder body or the cylinder rod is connected to annular ring gear 61, and the other is connected to the bottom or the middle part of the platform bracket 4. For example, in the present embodiment, the cylinder body is hinged to the annular ring gear 61, and the cylinder rod is hinged to the bottom of the platform bracket 4, and the pushing hydraulic cylinder 12 can push the platform bracket 4 to rotate in a direction away from the supporting upright column 1 around a hinged position at the top thereof.
