Description

Technical Field

[0001] The present invention relates to the field of parking equipment, and more particularly to a vertical circulating three-dimensional garage. Background Art

[0002] With the rapid growth of the number of automobiles, parking difficulty has become an important problem faced in urbanization development. The vertical circulating three-dimensional garage has attracted more and more attention due to its advantages such as small floor area, high land space utilization rate, and flexible layout. Typically, the vertical circulating three-dimensional garage can drive a transmission mechanism through a reduction motor to drive a plurality of car hanging baskets arranged at intervals on a traction chain to circulate in a runway-shaped (ring-shaped) operation area along with the traction chain, so as to achieve the purpose of storing and retrieving vehicles.

[0003] In recent years, new energy vehicle technologies represented by electric vehicles have become increasingly mature, and vertical circulating three-dimensional garages with charging functions have emerged as the times require. However, in order to supply power to charging components (such as charging piles and charging guns) on each car hanging basket, it is necessary to set up components and structures such as power transmission lines for power transmission, which faces new technical problems in terms of use safety, device layout, etc.

[0004] In the prior art, the most common power transmission device for vertical circulating three-dimensional garages is a sliding contact wire, which provides power for charging electric vehicles by keeping the charging components on the car hanging basket electrically connected to a conductive slide rail and a chute at different parking positions of the car hanging basket. For example, Chinese Utility Model Patent CN205476693U discloses a continuous charging system for parking spaces in a high-rise vertical circulating three-dimensional garage, which is provided with an annular groove-type conductive slide rail arranged around a rotating chain and a plurality of current collecting devices evenly distributed on the rotating chain. The current collecting device always contacts the annular groove-type conductive slide rail during the operation along with the rotating chain to obtain the power provided to the charging piles at each parking space. Such a power transmission device is difficult to meet the requirements of outdoor electrical safety protection and is not conducive to ensuring the use safety of users.

[0005] For example, the prior art of Chinese Utility Model Patent CN204793973U also provides a power supply solution using a charging cable to transmit power. Specifically, a charging wire reel rotator that rotates synchronously with the circulating guide rail is added to the circulating guide rail of the vertical selected three-dimensional garage. The charging wire is wound around the reel and connected to a charging gun on the car carrier plate at one end and a following turntable arranged outside the circulating guide rail at the other end. Thus, during the process of storing and retrieving vehicles, the charging wire reel rotator rotates synchronously with the circulating guide rail, and at the same time drives the following turntable, so that the charging wire circulates and is wound and released between the two. This power supply solution can effectively avoid the use safety problems caused by live components, but during the process of winding and releasing the charging wire, there will inevitably be a frictional effect between the charging cable and related components, resulting in problems such as high operation energy consumption and cable wear. Summary of the Invention

[0006] The object of the present invention is to overcome the problem that the charging line is inconvenient to arrange in the existing vertical circulating stereo garage, and to provide a vertical circulating stereo garage. This vertical circulating stereo garage does not need to change the outlet position along with the movement of the car hanging basket, and does not need to make the charging cable enter or pull out from the wire duct, which can effectively avoid problems such as energy consumption and wear caused by winding and releasing the charging cable, and outdoor power use / power-on safety.

Detailed description of the specific embodiment

[0030] The following will describe the specific embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiment described here is only used to illustrate and explain the present invention and is not used to limit the present invention.

[0031] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower" generally refer to the upper and lower as shown in the reference drawings; "inner, outer" refer to the inner and outer relative to the contour of each component itself. For the convenience of clear description, considering that when a car is parked in the vertical circulating stereo garage, it usually drives in from the front side of the vertical circulating stereo garage, that is, along Figure 2 and Figure 4 the car driving direction A shown in, so the orientation terms "front, rear" used in the present invention usually correspond to Figure 2 and Figure 4The left and right shown, such as the front main frame 1 and the rear main frame 2; the orientation words "left and right" used usually correspond to Figure 1 the left and right shown (i.e., Figure 4 the up and down shown).

[0032] Referring to Figures 1 to 4 shown, a vertical circulating three-dimensional garage according to a preferred embodiment of the present invention includes a rack, a plurality of car hanging baskets 8, a charging system, etc. Among them, the rack includes a front main frame 1 and a rear main frame 2 which are arranged opposite to each other at intervals. Towing chains 6 are respectively installed on the front main frame 1 and the rear main frame 2. In order to facilitate showing the key components and their connection relationships, Figure 1 only the rear main frame 2 viewed from the vertical section perspective towards the rear and the related components connected thereto are shown, and the towing chain 6 shown is the towing chain installed on the rear main frame 2. Generally, the rack can be welded by steel profiles and serves as the installation foundation and load-bearing foundation for functional components such as car hanging baskets.

[0033] In order to make the rack have higher overall stability, in a vertical circulating three-dimensional garage according to a preferred embodiment of the present invention, an upper frame 3 and a lower frame 4 are connected between the front main frame 1 and the rear main frame 2. It can be understood that the front main frame 1 and the rear main frame 2 can also be fixed to the ground through anchor bolts, and a reinforced concrete foundation is set to enhance the integrity of the two at the lower end.

[0034] The towing chains 6 installed on the front main frame 1 and the rear main frame 2 can be respectively arranged in a runway shape in the vertical plane and opposite to each other, and can be driven by a driving device such as a motor and a transmission device such as a sprocket 7 to run along their respective extending directions. A plurality of car hanging baskets 8 are respectively (through the hanging basket mounting frame 14) connected to different positions of the towing chain 6 and are connected to be able to pivot relative to the towing chain 6, so as to be able to move to different parking positions in the annular running area as the towing chain 6 runs and remain horizontal at each parking position. It can be understood that as the towing chain 6 runs, the car hanging basket 8 moves along the extending direction of the towing chain 6. However, in order to keep the car 30 parked reliably, the car hanging basket 8 should remain horizontal, so the car hanging basket 8 needs to be connected to be able to pivot relative to the towing chain 6.

[0035] Moreover, as the car hanging baskets 8 move between different parking positions, the running areas of all the car hanging baskets 8 exactly form an annular running area (when the car hanging baskets 8 are not allowed to move along the towing chain 6 for a full week, a single car hanging basket 8 can only pass through a part of the annular running area), and at different vertical cross-section positions, the cross-section of the annular running area and the runway-shaped plane surrounded by the towing chain 6 all form similar figures parallel to each other. To Figure 1Taking the vertical circulating multi-story garage shown as an example, which has eight uniformly distributed car baskets 8a - 8h, such as the first car basket 8a to the eighth car basket 8h. When the traction chain 6 is driven to run counterclockwise, when the first car basket 8a moves to the position of the second car basket 8b, the second car basket 8b just moves to the position of the third car basket 8c. That is to say, (assuming) when each car basket 8 is allowed to move one week along the traction chain 6, the spatial regions swept by each car basket 8 overlap each other, that is, the annular running region. In other embodiments, the vertical circulating multi-story garage may also have other numbers of car baskets 8, such as 12, 16, etc.

[0036] A charging component is provided on the car basket 8, such as a charger 15 and a charging gun 16 electrically connected to the charger 15. As shown in the figure, all eight car baskets 8 are provided with charging components. In other embodiments, the charging components may also be provided only on some of the car baskets 8, so that only some of the parking spaces in the vertical circulating multi-story garage have the charging function. In order to supply power to the charging components, in addition to the charging components, the charging system further includes a central outlet unit and a plurality of charging cables 9 that correspondingly diverge and extend from the central outlet unit to each of the charging components. In other words, the charging cables 9 connecting each charging component are concentrated at the central outlet unit and diverge and extend. Among them, the central outlet unit is electrically connected to an external power source such as a power supply cabinet 13, so as to be able to supply power to the charging components through the charging cables 9.

[0037] Importantly, in the vertical circulating multi-story garage of the present invention, there is a completely empty area 100 in the space surrounded by the annular running region where the aforementioned car basket 8 is located, and the outlet end of the central outlet unit is arranged in the completely empty area 100. The completely empty area 100 described here means that there are no components in this area that can stop the charging cable 9, such as the connecting rod connected between the front main frame 1 and the rear main frame 2 in the traditional technology, the transmission shaft connecting the front and rear traction chains 6, etc., so as to avoid movement interference with the charging cable 9 when the car basket 8 moves along with the traction chain 6. The outlet end of the central outlet unit refers to one end of the extended part of the charging cable 9 led out from the central outlet unit to the charging component.

[0038] To better understand the meaning of the aforementioned completely empty area 100, now in combination with Figure 4A description will be given of the horizontal section shown. Among them, the I-shaped area shown by the cross-section line part is the space surrounded by the annular running area of the vehicle hanging basket, and the full-empty area 100 is located in this space. Specifically, the vehicle hanging basket 8 may include a hanging basket cross beam 81 pivotally connected to the hanging basket mounting frame 14 (so as to be able to pivot relative to the traction chain 6), a vehicle support plate 82, a hanging basket rod 83 connected between the hanging basket cross beam 81 and the vehicle support plate 82, and a hanging basket stabilizer bar 85 connected with rollers 84 described later (in combination with Figure 2 shown). Among them, at different positions in the front-rear direction, the distances between two vehicle hanging baskets 8 at the same height position are different, thus forming the I-shaped cross-section area shown in the figure.

[0039] On the side close to the front main frame 1, the hanging basket cross beam 81 has a forward extension length F relative to the vehicle support plate 82 so as to connect the hanging basket mounting frame 14. Then, the space defined by the hanging basket cross beam 81, the front-side hanging basket mounting frame 14, and the vehicle support plate 82 can be used as the full-empty area 100; on the side close to the rear main frame 2, the hanging basket stabilizer bar 85 has a backward extension length H relative to the vehicle support plate 82. Then, the space defined by the hanging basket stabilizer bar 85, the vehicle support plate 82, and the rear-side hanging basket mounting frame 14 within the left-right distance G between the two hanging basket stabilizer bars 85 can be used as the full-empty area 100; the space between the above two areas is defined by the edges of each vehicle support plate 82 and can also be used as the full-empty area 100. These full-empty areas 100 can all be used to set the outlet ends of the central cable outlet unit. And since each component of the vehicle hanging basket 8 moves within the annular running area, Figure 4 the cross-section line parts shown all represent the three-dimensional space surrounded by the annular running area.

[0040] When the full-empty area 100 is selected at different positions corresponding to the vehicle hanging basket 8, the dimensions of relevant components can be appropriately set to provide sufficient space for accommodating the charging cable 9. For example, when the outlet end of the central cable outlet unit is set on the side close to the rear main frame 2, the rear-end extension length of the hanging basket cross beam 81 can be appropriately increased (such as 200 mm - 800 mm). Similarly, the same is true for the front side. In addition, different from the traditional technology that reduces the overall width considering the space layout, the present invention can increase the horizontal distance E between the vehicle hanging baskets 8 on both sides of the central cable outlet unit to 400 mm - 800 mm for the layout of the central cable outlet unit and the free sag of the charging cable 9.

[0041] It should be understood that the setting of the full-empty area 100 is mainly used to ensure that the charging cable 9 is not interfered during the movement of the vehicle hanging basket 8. Therefore, it is only necessary to avoid the existence of interfering components in this full-empty area 100, without preventing the setting of components in the space other than the full-empty area 100 surrounded by the annular running area where the vehicle hanging basket 8 is located. For example, in Figure 6In the preferred embodiment shown, the fully empty area 100 is located on one side close to the rear main frame 2. The outlet end of the central cable outlet unit (such as the cable passing frame 5 and the rotary ferrule 22, etc.) is arranged within this fully empty area 100. And in the front space surrounded by the annular running area where the vehicle hanging basket 8 is located, inclined tie rods can be arranged (connected between the front main frame 1 and the cable passing frame 5 to improve the stability of the cable passing frame 5), rather than being in a fully empty state.

[0042] Through the above technical solution, the vertical circulating three-dimensional garage of the present invention centrally outlets and diverges through the central cable outlet unit with its outlet end arranged within the fully empty area 100. The charging cable 9 can freely droop within this fully empty area 100 without being blocked or interfered by any components (such as tie rods, transmission shafts, and the vehicle hanging basket 8). There is no need to change the cable outlet position along with the movement of the vehicle hanging basket 8, and there is no need to make the charging cable 9 enter or be pulled out from the cable trough, thereby avoiding problems such as energy consumption, wear, and power supply / supply safety caused by winding and releasing the charging cable.

[0043] In the present invention, as long as the area corresponding to the outlet end of the central cable outlet unit constitutes a fully empty area 100 allowing each charging cable 9 to freely droop, this fully empty area 100 can be located at any position within the space surrounded by the annular running area where the vehicle hanging basket 8 is located. However, if the outlet end of the central cable outlet unit is offset relative to the upper or lower side or the left or right side, it will cause at least some of the charging cables 9 to have a relatively long extension length between the central cable outlet unit and the charging component, and knots are likely to occur. For this reason, the central cable outlet unit can be arranged on the vertical central plane where the running centers of the front and rear traction chains 6 are located (i.e., Figure 4 the vertical plane where the center line shown by the dotted line in the figure is located). Further, the central cable outlet unit is arranged on the center line where the running centers of the front and rear traction chains 6 are located. Thus, it can be set so that the charging cables 9 from the central cable outlet unit to each charging component have the same extension length, avoiding problems such as knotting and waste caused by excessive length. For example, in Figure 1 the preferred embodiment shown, the charging cable 9 can be made to extend basically in a straight line when the corresponding vehicle hanging basket 8 runs to the highest or lowest position (the positions where the first vehicle hanging basket 8a and the fifth vehicle hanging basket 8e are located), effectively preventing problems such as knotting.

[0044] As described above, in order to improve the overall stability, the upper frame 3 can be connected between the front main frame 1 and the rear main frame 2. In the illustrated preferred embodiment, the upper frame 3 is connected to the tops of the front main frame 1 and the rear main frame 2. In other embodiments, as long as the upper frame 3 is located above the annular running area where each vehicle hanging basket 8 is located, it can avoid affecting the movement of the charging cable 9 and the vehicle hanging basket 8.

[0045] Since it is necessary to allow the fully empty area 100 to permit the extension part of the charging cable 9 between the central cable outlet unit and the charging component to droop freely when the vehicle hanging basket 8 moves to any position, the present invention omits the pull rod in the traditional technology and the transmission shaft of the traction chain that are respectively installed on the front main frame 1 and the rear main frame 2. In this case, the front and rear drive chains cannot be driven by a single power device, and single-sided drive is not conducive to maintaining the horizontal state of the vehicle hanging basket 8. In response to this, the preferred embodiment shown in the drawings of the present invention is provided with a front drive device 11 and a rear drive device 12 respectively for driving the traction chains 6 installed on the front main frame 1 and the rear main frame 2, thereby independently driving the traction chains 6 at the front and rear ends of the vehicle hanging basket 8. Here, in order to ensure synchronization, the power outputs of the front drive device 11 and the rear drive device 12 can be made consistent by an electrical control method.

[0046] The central cable outlet unit of the present invention can be set in various appropriate structural forms. In Figures 1 to 4 the preferred embodiment shown, the central cable outlet unit includes a central cable outlet 10 through which the charging cable 9 passes, and the charging cable 9 passes through this central cable outlet and is connected to the power supply cabinet 13. Thus, each charging cable 9 is directly connected from the power supply cabinet 13 to the charging components on each vehicle hanging basket 8, which can avoid potential electrical safety problems such as exposed joints, and can easily meet the requirements of the electrical safety protection level in line with relevant regulations. Among them, the outlet of the central cable outlet 10 can be set in a flared shape to reduce the wear of the charging cable 9 at this outlet.

[0047] In other alternative embodiments, the central cable outlet unit can be set as a collector slip ring that connects to the power supply cabinet through a single high-power main line, and each charging cable corresponding to different vehicle hanging baskets is led out from this collector slip ring. Or, the central cable outlet unit is set as a plurality of cable drums, and each charging cable corresponding to different vehicle hanging baskets is led out from each cable drum.

[0048] Figure 6 Shown is another preferred structural form of the central cable outlet unit. This central cable outlet unit includes a wire passing frame 5 connected to the front main frame 1 and a rotating collar 22 rotatably mounted on this wire passing frame 5. Each charging cable 9 extends from one side of the front main frame 1 into the space between the front main frame 1 and the rear main frame 2, and extends along the wire passing frame 5 to the free end near the rear main frame 2, and is fixed to the rotating collar 22 at this free end position. Thus, since the rotating collar 22 provides a degree of freedom of rotation for the charging cable 9, when the vehicle hanging basket 8 is driven by the traction chain 6 to move between different parking positions, the charging cable 9 can freely rotate on the wire passing frame 5 with the rotating collar 22, so as to reduce the influence on the torsional fatigue life of the charging cable 9 during operation. Among them, the connection structure between the rotating collar 22 and the charging cable 9, etc. Figure 7As shown, the charging cable 9 axially penetrates into the rotary ferrule 22 and radially extends from the rotary ferrule 22 into the full-empty area 100. The rotary ferrule 22 can be rotatably mounted on the wire passing frame 5 through a bearing 23.

[0049] In the above preferred embodiment, a fixed ferrule 21 can be provided at one end of the wire passing frame 5 close to the front main frame 1 for fixing the charging cable 9 when the charging cable 9 penetrates into the space between the front main frame 1 and the rear main frame 2, and the extended portion of the charging cable 9 between the two can be twisted at a small angle by the rotation of the rotary ferrule 22 relative to the fixed ferrule 21, which can better adapt to the torsional movement generated by the charging cable 9 during the movement of the car hanging basket 8. In addition, the charging cable 9 can be laid along the outer peripheral surface of the wire passing frame 5 as shown in the figure, or the wire passing frame 5 can be formed into a hollow structure so that the charging cable 9 passes through the wire passing frame 5 and extends to the rotary ferrule 22.

[0050] Although the present invention provides a full-empty space allowing the charging cable 9 to hang freely, if the traction chain 6 and the car hanging basket 8 always run in a fixed direction during the access of the car, it is easy to cause damage to the charging cable 9 due to excessive torsion. Generally, the user can simply achieve the car access process through the control panel, and the operation logic can be executed by the controller connected to the driving device by signal. As for whether the car hanging basket 8 runs clockwise or counterclockwise during the access of the car, it is not concerned by the user. In this case, the preferred embodiment of the vertical circulating three-dimensional garage of the present invention is set to only allow each car hanging basket 8 to perform a reciprocating movement within a limited number of circles in the annular running area, and the limited number of circles is preferably no more than one circle.

[0051] Combined with Figure 5 As shown, the eight car hanging baskets 8 are divided into two groups along the dividing line D. The first group includes the first car hanging basket 8a, the second car hanging basket 8b, the third car hanging basket 8c, and the fourth car hanging basket 8d, and the second group includes the fifth car hanging basket 8e, the sixth car hanging basket 8f, the seventh car hanging basket 8g, and the eighth car hanging basket 8h. For the convenience of example, their initial positions are located at the 1# to 8# parking spaces respectively.

[0052] At this time, if you want to pick up the car at the 5# parking space, the fifth car hanging basket 8e can be rotated counterclockwise C to the bottom 1# parking space, and at the same time, the fourth car hanging basket 8d at the initial position at the 4# parking space moves to the 8# parking space. At this time, if you need to pick up the car on the fourth car hanging basket 8d, you cannot continue to rotate counterclockwise to the 1# parking space along the shortest path, but should return clockwise B and rotate to the 1# parking space to pick up the car. Thus, the torsional damage of the charging cable 9 can be avoided as much as possible, and problems such as winding and knotting can be prevented.

[0053] In the above-described embodiment, the eight vehicle gondolas 8 are divided into two groups by the dividing line D, and the rotation directions of the two groups of vehicle gondolas 8 for accessing and storing vehicles are different from each other. Thus, an access and storage vehicle logic of a preferred embodiment is exemplarily illustrated. In other embodiments, the vehicle gondola 8 may be allowed to reciprocate within a range greater than one circle.

[0054] As described above, the vehicle gondola 8 may include a gondola cross beam 81, a vehicle pallet 82, gondola rods 83, a gondola stabilizer bar 85, etc., and may be connected by a gondola mounting bracket 14 to be pivotable relative to the traction chain 6 to maintain a horizontal state at different parking positions. Here, the gondola mounting bracket 14 may be a triangular bracket or a T-shaped bracket so as to be connected to the pins at both ends of the link of the traction chain 6. The vehicle gondola 8 is pivotally connected to the gondola mounting bracket 14 through its gondola cross beam 81 to be pivotable relative to the traction chain 6.

[0055] In the illustrated preferred embodiment, the charging components on each vehicle gondola 8 are arranged as a charger 15 mounted on the gondola cross beam 81 and a charging gun 16 electrically connected to the charger 15, thereby avoiding occupying the parking space of the vehicle pallet 82. In the front-rear direction, the charger 15 may be arranged at one end of the gondola cross beam 81 close to the front main frame 1 or the rear main frame 2. Among them, arranging the charger 15 at one end close to the front main frame 1 is beneficial to the free hanging of the charging cable 9, and the extension part of the charging cable 9 from the central wire outlet unit to the charger 15 does not need to consider the influence of the gondola stabilizer bar 85, and the charging cable 9 can be set to have a shorter extension length; arranging the charger 15 at one end close to the rear main frame 1 can reduce the influence on the vehicle driving into the vehicle gondola 8 without having to consider too much the occupation of the parking space by the size of the charger 15.

[0056] Furthermore, the charging cable 9 extends through the full-empty area 100 and is electrically connected to the charger 15 mounted on the vehicle gondola 8, so that the charging cable 9 has an extension part extending into the annular running area where the vehicle gondola 8 is located, and these extension parts should be guided so as to be connected to the charger 15 at an appropriate position (the left-right middle position of the vehicle gondola 8). For this purpose, a wire bracket 17 extending towards the full-empty area 100 may be connected to the gondola mounting bracket 14 on the side close to the charging components (such as the gondola mounting bracket 14 on the side close to the rear main frame 2 in the figure), and a cable fixing clip 18 is provided on the wire bracket 17 so that the extension part of the charging cable 9 extending into the annular running area where the vehicle gondola 8 is located is fixed relative to the corresponding vehicle gondola 8.

[0057] In order to prevent the charging cable 9 from being wound around the vehicle hanging basket 8 due to accidental external effects (such as strong wind), a cable protection cover 19 can also be installed on the front main frame 1 or the rear main frame 2 to cover the extension of the charging cable 9 from the central outlet unit to the wire bracket 17. Thus, the internal space of the cable protection cover 19 is a completely empty area 100 that allows the charging cable 9 to droop freely.

[0058] In the illustrated preferred embodiment, the rear main frame 2 is further connected with a track 20. One end of the vehicle hanging basket 8 facing the rear main frame 2 is provided with a roller 84 that cooperates with the track 20, and the roller 84 can be arranged at one end of the hanging basket stabilizer bar 85 facing the rear main frame 2.

[0059] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Within the technical concept scope of the present invention, various simple modifications can be made to the technical solutions of the present invention, including any suitable combination of each specific technical feature. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods. But these simple modifications and combinations should also be regarded as the content disclosed by the present invention and all fall within the protection scope of the present invention.
