Description

Technical Field

[0001] The present invention relates to the field of parking equipment, in particular to a vertical circulation stereo garage. Background Art

[0002] With the rapid growth of car ownership, parking difficulties have become a major challenge facing urbanization. Vertical circulation parking garages are gaining increasing attention due to their small footprint, high land utilization, and flexible layout. Typically, a vertical circulation parking garage uses a geared motor to drive a transmission mechanism, driving multiple car hanging baskets spaced apart on a traction chain. These traction chains circulate within a runway-shaped (circular) operating area to facilitate vehicle storage and retrieval.

[0003] To ensure the synchronized operation of the traction chains at the front and rear ends of the vehicle basket, traditional vertical circulation parking garages typically coaxially connect front and rear paddle wheels, which mate with the lower portions of the front and rear traction chains, respectively. This allows the front and rear paddle wheels to rotate when the drive motor drives one, driving the other to rotate synchronously, thereby driving the front and rear traction chains to operate synchronously. In this case, a transmission shaft is connected between the front and rear paddle wheels for transmission. The axis of the transmission shaft is colinear with the center of the front and rear paddle wheels. For example, the front and rear paddle wheels can be directly fixed to the ends of the transmission shaft.

[0004] This transmission form of the drive shaft has seriously restricted the development of vertical circulation stereo garage technology. For example, with the increasing maturity of new energy vehicle technology represented by electric vehicles, vertical circulation stereo garages with charging functions have emerged. In order to avoid unnecessary energy consumption and wear of the charging cable during the process of being released and entangled with the movement of the car basket, the charging cables connecting multiple car baskets can be arranged as centralized outlets, and extended divergently from the outlet unit to each car basket. However, since this outlet method requires a sufficient extension length of the charging cable to be reserved between the outlet unit and the car basket to adapt to the different parking positions of the car basket, it is required to provide a full empty space in the space surrounded by the annular operating area of the car basket to avoid or reduce the impact of the above-mentioned drive shaft on the arrangement and service life of the charging cable. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problem in the prior art that the existence of a drive shaft in a vertical circulation stereo garage restricts the arrangement and operation of components, and to provide a vertical circulation stereo garage that releases the space between the front and rear dial wheels to improve the convenience of arranging components and equipment such as charging cables.

[0006] In order to achieve the above object, the present invention provides a vertical circulation stereo garage, comprising:

[0015] Preferably, the driving motor has a brake device, the brake device has a brake lever for releasing the brake state, and the brake lever is connected to a brake cable.

[0016] Preferably, the central transmission shaft is arranged in a space surrounded by the annular operating area where the plurality of vehicle hanging baskets are located.

[0017] Preferably, the central transmission shaft is arranged on the vertical center plane where the running center of the traction chain respectively installed on the front main frame and the rear main frame is located, and / or the height position of the central transmission shaft is 0-2.5m higher than the line connecting the centers of the areas surrounded by the traction chains respectively installed on the front main frame and the rear main frame.

[0018] Preferably, the vertical circulation multi-story parking garage includes a charging system, which includes a central outlet unit arranged around the central transmission shaft, charging components respectively provided on the car hanging baskets, and a plurality of charging cables extending from the central outlet unit to each of the charging components so as to supply power to the charging components.

[0019] Preferably, a cable bracket is sleeved on the central transmission shaft, with two ends respectively connected to the front main frame and the rear main frame, and the central outlet unit is installed on the cable bracket to be arranged around the central transmission shaft.

For example, in a vertical circulation multi-story parking garage with a charging function with a central centralized line output, the extension length of the charging cable can be relatively moderate, which is convenient for free arrangement and can avoid damage caused by bending and extending around the transmission shaft.

DETAILED DESCRIPTION

[0032] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0033] In the present invention, unless otherwise specified, directional words such as "upper" and "lower" generally refer to the upper and lower parts shown in the accompanying drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself. For the sake of clarity, considering that when parking a car in a vertical circulation stereo garage, it is usually driven into the vertical circulation stereo garage from the front side, that is, along the Figure 1 and Figure 5 The direction of the car shown in the figure is from left to right, so the directional words "front" and "back" used in the present invention usually correspond to Figure 1 and Figure 5 The left and right shown, such as the front main frame 1 and the rear main frame 2; the directional words "left" and "right" usually correspond to Figure 3 Left and right shown.

[0034] Reference Figures 1 to 3As shown in the figure, a vertical circulation stereo garage according to a preferred embodiment of the present invention includes a frame, multiple car hanging baskets 4 and a drive system. The frame includes a front main frame 1 and a rear main frame 2 arranged opposite to each other, and a traction chain 5 is installed on each of the front main frame 1 and the rear main frame 2. In order to facilitate the representation of key components and their connection relationships, Figure 1 Only some relevant components observed from a vertical cross-sectional perspective are shown, while traction chains, etc. are omitted. Generally, the frame can be welded from steel profiles and serves as an installation base and a load-bearing base for functional components such as the vehicle hanging basket 4.

[0035] To ensure a high overall stability of the frame, in a preferred embodiment of the vertical circulation multi-story parking garage of the present invention, an upper frame 3 and a lower frame may be connected between the front main frame 1 and the rear main frame 2. It is understood that the front main frame 1 and the rear main frame 2 may also be fixed to the ground with anchor bolts, and a reinforced concrete foundation may be provided to enhance the integrity of the two at their lower ends.

[0036] The traction chains 5 mounted on the front main frame 1 and the rear main frame 2 can be arranged in a runway pattern in a vertical plane and relative to each other. They can be driven to run along their respective extension directions by a drive device, such as a motor, and an intermediate transmission mechanism, such as a front paddle wheel 6 and a rear paddle wheel 7. Multiple vehicle hanging baskets 4 are connected to different positions of the traction chain 5 (via, for example, a hanging basket triangular plate 30) and are connected to pivot relative to the traction chain 5 so as to move to different parking positions within the circular operating area as the traction chain 5 operates, and to remain horizontal at each parking position. It is understood that as the traction chain 5 operates, the vehicle hanging baskets 4 move along the extension direction of the traction chain 5. However, in order to keep the car (not marked) securely parked, the vehicle hanging baskets 4 must remain horizontal, and therefore, the vehicle hanging baskets 4 must be connected to pivot relative to the traction chain 5.

[0037] Furthermore, as the car basket 4 moves between different parking positions, the operating areas of all the car baskets 4 form a circular operating area (when the car basket 4 is not allowed to move a full circle along the traction chain 5, a single car basket 4 can only pass through a portion of the circular operating area), and at different vertical cross-sectional positions, the cross-section of the circular operating area and the runway-shaped plane surrounded by the traction chain 5 form similar figures parallel to each other. Figure 3Taking the vertical circulation stereo garage with eight evenly distributed car baskets 4 as an example, when the traction chain 5 is driven counterclockwise so that the bottom car basket 4 moves to the position of the top car basket 4, the top car basket 4 moves to the position of the bottom car basket 4. In other words, (assuming) when each car basket 4 is allowed to move one circle along the traction chain 5, the spatial areas swept by each car basket 4 overlap with each other, i.e., the circular operation area. In other embodiments, the vertical circulation stereo garage may also have other numbers of car baskets, such as 12, 16, etc.

[0038] The vertical circulation multi-story parking garage of the present invention also has a drive system, including a front paddle wheel 6, a rear paddle wheel 7, and an intermediate transmission mechanism that is transmission-connected between the front paddle wheel 6 and the rear paddle wheel 7. The front paddle wheel 6 cooperates with the traction chain 5 installed on the front main frame 1, and the rear paddle wheel 7 cooperates with the traction chain 5 installed on the rear main frame 2. The intermediate transmission mechanism includes a central transmission shaft 8 that extends between the front main frame 1 and the rear main frame 2 and is offset relative to the wheel centers of the front paddle wheel 6 and the rear paddle wheel 7. The central transmission shaft 8 can be pivotally mounted on the front main frame 1 and the rear main frame 2 via a bearing seat 25. In order to facilitate disassembly and assembly, the central transmission shaft 8 can be multiple sections connected by couplings.

[0039] Therefore, unlike the traditional technology in which the drive shaft and the front and rear pulleys are coaxially arranged at the bottom end of the annular area surrounded by the traction chain, the present invention sets the central drive shaft 8 for transmission to be offset from the wheel center relative to the front pulley 6 and the rear pulley 7, thereby releasing the space between the front pulley 6 and the rear pulley 7 in the space surrounded by the annular operation area of the automobile basket 4. In a vertical circulation multi-story parking garage with a charging function, for example, with a central centralized line output, the extension length of the charging cable can be relatively moderate, which is convenient for free arrangement and can avoid damage caused by bending and extending around the drive shaft.

[0040] In other words, the vertical circulation parking garage of the present invention features a drive system layout structure that is completely different from conventional technologies. By placing the central drive shaft 8 offset from the front and rear paddle wheels 6 and 7, the central drive shaft 8 is positioned "farther than near," significantly improving the layout convenience of related components and equipment. For example, when a freely extending charging cable needs to be arranged within the space surrounding the circular operating area of the vehicle basket 4, the charging cable does not need to be routed around the bottom drive shaft connected between the front and rear paddle wheels 6 and 7 as in conventional technologies. Therefore, its extended length does not need to be excessively long to meet the charging needs of the vehicle basket at different parking positions, and damage caused by large bending angles of the charging cable can be avoided.

[0041] It should be noted that while the present invention proposes a drive system layout structure based on the technological development needs of vertical circulation parking garages with charging functions and solves the problem of the transmission shaft affecting the layout and service life of charging cables, the vertical circulation parking garage of the present invention is not limited to charging garages and can also be a non-charging garage. By utilizing the central transmission shaft 8 to transmit power between the front paddle wheel 6 and the rear paddle wheel 7, space can be freed up in the garage relatively close to the ground, which can be used to arrange any other safety facilities besides the above-mentioned charging cables, such as fire hoses that can be connected to the front main frame 1 and the rear main frame 2 to extend into this space.

[0042] To avoid occupying a large space, as shown, the central drive shaft 8 is disposed within the space surrounding the annular operating area of the vehicle basket 4. In other embodiments, the central drive shaft 8 can also be disposed at another location offset from the center of the front and rear paddle wheels 6 and 7, as long as it does not interfere with the operation of the vehicle basket 4. Preferably, the central drive shaft 8 is disposed on the vertical center plane of the operating center of the traction chains 5 mounted to the front and rear main frames 1 and 2, respectively, so that the distance between the central outlet unit 27, described later, and each vehicle basket 4 is substantially equal.

[0043] In the illustrated preferred embodiment, the front paddle wheel 6 and the rear paddle wheel 7 are coaxially arranged near the lower portion of the traction chain 5 and engage with the corresponding traction chain 5 on the front main frame 1 and the rear main frame 2, respectively. In other embodiments, the front paddle wheel 6 and the rear paddle wheel 7 may engage with different positions of the traction chain 5. For example, the front paddle wheel 6 may still engage with the lower portion of the traction chain 5 mounted on the front main frame 1 as shown, while the rear paddle wheel 7 engages with the upper portion of the traction chain 5 mounted on the rear main frame 2. Maintaining the front paddle wheel 6 and the rear paddle wheel 7 in the same position as in conventional technology facilitates installation and maintenance.

[0044] As described above, in a preferred embodiment, the central transmission shaft 8 can be located near the middle of the traction chain 5 in the height direction relative to the front and rear pulleys 6 and 7, freeing up space below. In this case, the central transmission shaft 8 has a significant radial offset relative to the front and rear pulleys 6 and 7, resulting in a longer power transmission path. To this end, a chain drive can be used to transmit power between the front and rear pulleys 6 and the central transmission shaft 8, and between the central transmission shaft 8 and the rear pulleys 7. Specifically, the intermediate transmission mechanism for power transmission between the front and rear pulleys 6 and 7 can include a first chain drive connected between the front and rear pulleys 6 and the central transmission shaft 8 and positioned near the front main frame 1, and a second chain drive connected between the central transmission shaft 8 and the rear pulleys 7 and positioned near the rear main frame 2. This not only meets the transmission requirements for a longer path, but also facilitates synchronized rotation of the front and rear pulleys 6 and 7 by appropriately setting the sprocket diameters or transmission ratios.

[0045] For example, in the illustrated preferred embodiment, the front paddle wheel 6 and the rear paddle wheel 7 are each mounted on the frame via a bearing seat 25. A first sprocket 13 is coaxially mounted on the axle on which the front paddle wheel 6 is mounted. The first sprocket 13 is coupled to a first chain 21 that is also coupled to a second sprocket 14. The second sprocket 14 is coaxially mounted with a third sprocket 15. The third sprocket 15 is coupled to a second chain 22 that is also coupled to a fourth sprocket 16. The fourth sprocket 16 is fixedly connected to the central transmission shaft 8. Thus, the first sprocket 13, the second sprocket 14, the third sprocket 15, the fourth sprocket 16, and the first and second chains 21, 22 connected therebetween constitute the aforementioned first chain transmission device, capable of transmitting power from the front paddle wheel 6 to the central transmission shaft 8. Symmetrically, the second chain transmission device may include a fifth sprocket 17 fixedly mounted on the central transmission shaft 8, a sixth sprocket 18 and a seventh sprocket 19 coaxially mounted thereon, an eighth sprocket 20 coaxially mounted with the rear derailleur 7, and a third chain 23 and a fourth chain 24 connected therebetween, for transmitting power from the central transmission shaft 8 to the rear derailleur 7. The two sprockets connected to the same chain may have the same number of teeth, such as the first sprocket 13 and the second sprocket 14 having the same specifications, and the third sprocket 15 and the fourth sprocket 16 having the same specifications, thereby achieving a transmission ratio of 1 for the first chain transmission device.

[0046] In this preferred embodiment, the first and second chain transmissions each utilize a two-stage transmission. In other embodiments, a single-stage transmission or a multi-stage transmission may be employed between the central transmission shaft 8 and the front and / or rear paddle wheels 6 and 7, depending on factors such as the height of the parking spaces in the garage.

[0047] Through the aforementioned intermediate transmission mechanism, the front paddle wheel 6 and the rear paddle wheel 7 can be driven to rotate synchronously, thereby driving the traction chains 5 mounted on the front main frame 1 and the rear main frame 2, respectively, to operate synchronously. In this case, as long as any one of the drive systems is driven, the parking and retrieval operations of the vertical circulation parking garage can be realized. Typically, the drive system includes a drive motor 9 mounted on one of the front main frame 1 and the rear main frame 2. One of the front paddle wheel 6 and the rear paddle wheel 7 can be driven by the drive motor 9 and driven synchronously by the other through the intermediate transmission mechanism. In the preferred embodiment shown in the figure, the drive motor 9 is mounted on one side of the front main frame 1. A motor sprocket 10 is mounted on its power output shaft. The motor sprocket 10 is connected to a driving sprocket 12 mounted coaxially with the front paddle wheel 6 via a front drive chain 11. The driving sprocket 12 has a larger number of teeth than the motor sprocket 10. As a result, the power output by the drive motor 9 can be reduced in speed and transmitted to the front paddle wheel 6, which then drives the rear paddle wheel 7 to rotate synchronously through the intermediate transmission mechanism.

[0048] Figure 4The transmission path from the drive motor to the vehicle basket is shown. The drive motor 9 outputs power, which is transmitted via the motor sprocket 10 and the front drive chain 11 to the driving sprocket 12, achieving speed reduction and torque increase. The driving sprocket 12, the front paddle wheel 6, and the first sprocket 13 are mounted on the same shaft and rotate synchronously. The front paddle wheel 6 drives the traction chain 5 mounted on the front main frame 1. The rotation of the first sprocket 13 is transmitted sequentially through the first chain 21, the second sprocket 14, the third sprocket 15, and the second chain 22 to the fourth sprocket 16. Since the fourth sprocket 16 is fixed to the central drive shaft 8, the central drive shaft 8 is driven to rotate. Furthermore, the central drive shaft 8 continues to output power rearward via the fifth sprocket 17 near one end of the rear main frame 2, driving the eighth sprocket 20 through the third chain 23, the sixth sprocket 18, the seventh sprocket 19, and the fourth chain 24. The eighth sprocket 20 is mounted on the same axis as the rear paddle wheel 7, thereby driving the traction chain 5 mounted on the rear main frame 2 and the traction chain 5 mounted on the front main frame 1 to operate synchronously. The traction chains 5 mounted on the front and rear main frames 1 and 2 drive the basket triangular plates 30 at the front and rear ends of the vehicle basket 4 to move along the extension direction of the traction chains 5, thereby changing the position of the vehicle basket 4. During this process, the vehicle basket 4 pivots relative to the basket triangular plates 30 and the traction chains 5 to maintain a horizontal position.

[0049] In the event of a power outage in the garage, the drive motor 9 can be configured to automatically brake to prevent accidents. To this end, a braking mechanism can be incorporated into the drive motor 9. This mechanism can include a brake lever 91 for releasing the brake state, connected to a brake cable 92. This allows the brake state of the drive motor 9 to be manually released, making it easier to remove a car parked in the garage during a power outage. To facilitate operator control, the brake cable 92 can be extended downward from the drive motor 9 to a position close to the ground.

[0050] Furthermore, a charging component 28, such as a charger and a charging gun electrically connected to the charger, may be provided on the car basket 4. Each car basket 4 may be provided with a charging component. In other embodiments, charging components may be provided only on some car baskets 4, so that only some parking spaces in the vertical circulation stereo garage have a charging function. In order to provide power to the charging component, in addition to the charging component, the charging system also includes a central outlet unit 27 and a plurality of charging cables 29 extending from the central outlet unit 27 to each of the charging components 28. In other words, the charging cables 29 connecting the various charging components 28 are centrally outlet at the central outlet unit 27 and extend divergently. The central outlet unit 27 is electrically connected to an external power source such as a power supply cabinet so that power can be supplied to the charging component 28 through the charging cable 29.

[0051] like Figure 1As shown, in a preferred embodiment, to prevent the aforementioned central drive shaft 8 from interfering with the arrangement and extension of the charging cable 29, a cable bracket 26 can be mounted on the central drive shaft 8, with its ends connected to the front main frame 1 and the rear main frame 2, respectively. A central outlet unit 27 is mounted on the cable bracket 26 to surround the central drive shaft 8. As a result, as the charging cable 29 extends from the central outlet unit 27 to the charging assembly 28 on each vehicle basket 4, the space surrounding the annular operating area of the vehicle basket 4 is free of any components to block the extension of the charging cable 29. This allows the charging cable 29 to droop freely, avoiding bending around the axis. The charging cable, which connects to the central outlet unit 27 from an external power source, can extend along the cable bracket 26, essentially securing it to the outer surface or interior of the cable bracket 26.

[0052] Typically, the charging assembly 28 can be hoisted on the end of the vehicle basket 4 close to the rear main frame 2 to avoid affecting the vehicle from entering the vehicle basket 4 from the side of the front main frame 1. In other embodiments, the charging assembly 28 can also be hoisted on the end of the vehicle basket 4 close to the front main frame 1 or directly mounted on the vehicle tray, etc.

[0053] Figure 5 The figure shows a schematic diagram of another preferred embodiment of the vertical circulation stereo garage of the present invention. Its drive system and other structures are the same as those of the aforementioned preferred embodiment and will not be described in detail below. Figure 1 The preferred embodiment shown mainly focuses on the extension path of the charging cable 29 and the arrangement of related components.

[0054] Specifically, unlike the aforementioned central outlet unit, which is located near the charging assembly (at the rear end) of the cable support, the central outlet unit 27 in this preferred embodiment is installed midway along the cable support 26. This allows the charging cable 29 to have a larger bending radius when extending from the central outlet unit 27 to the charging assembly 28, thereby reducing bending damage. The midway point of the cable support 26 in this context refers to or is adjacent to the midpoint of the cable support 26 in the front-to-back direction of the garage. Specifically, the central outlet unit 27 is installed near the midpoint of the cable support 26 in the front-to-back direction of the garage.

[0055] In the preferred embodiment shown in the figure, the charging assembly 28 is arranged at one end of the vehicle hanging basket 4 close to the rear main frame 2, and the charging cable 29 extends from the central outlet unit 27 toward the side of the front main frame 1 to each vehicle hanging basket 4, and extends along the upper beam of the vehicle hanging basket 4 to the charging assembly 28. Figure 1 In the preferred embodiment shown, the charging cable 29 extends from the front side of the vehicle basket 4 to avoid interference with the guide wheel support rod, making the wiring arrangement more convenient.

[0056] The charging cable 29 can extend from the charging cabinet, through the rear main frame 2 to the area between the front main frame 1 and the rear main frame 2, and then extend along the cable bracket 26 to the central outlet unit 27. The charging cable 29 passes through the central outlet unit 27 and extends to each vehicle basket 4 accordingly, thereby avoiding the presence of cable joints in the extension area from the charging cabinet to the vehicle basket 4 and reducing the risk of leakage.

[0057] The portion of the cable support 26 between the central outlet unit 27 and the front main frame 1 also features a free-standing collar 31, allowing it to rotate freely on the cable support 26. This allows the portion of the charging cable 29 extending from the central outlet unit 27 to the charging assembly 28 to be separated from the cable support 26. As the charging cable 29 hangs freely within this space, it can rotate freely on the cable support 26 along with the collar 31, minimizing wear.

[0058] Theoretically, in the preferred embodiment described above, the central outlet unit 27 is positioned at the same distance from the charging assembly 28 on the top and bottom vehicle baskets, ensuring that the charging cable 29 has the shortest possible extension distance after extending from the central outlet unit 27. However, to avoid tension damage caused by dimensional errors, the charging cable 29 is typically longer than the theoretical length. In this case, the center of the area surrounded by the traction chain is equidistant from the top and bottom vehicle baskets' upper beams. If the central outlet unit 27 is positioned at this height, the freely drooping charging cable 29 may contact the upper beam of the bottom vehicle basket, causing wear. To this end, the central outlet unit 27 (i.e., the central drive shaft 8) can be positioned at a height of 0-2.5 m above the line connecting the centers of the areas surrounded by the two traction chains mounted on the front main frame 1 and rear main frame 2 to avoid or minimize contact between the charging cable, which has a sufficient length, and the top beam of the bottom vehicle basket while freely drooping.

[0059] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, the technical solution of the present invention may be subjected to a variety of simple modifications, including combining the various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as disclosed in the present invention and fall within the scope of protection of the present invention.
