Description

Technical Field

[0001] This invention relates to the field of automated parking system technology, and in particular to a vehicle platform exchange device, a vehicle transporter, and an automated parking system. Background Technology

[0002] Currently, platform parking spaces are widely used in various types of automated parking systems, including vertical lifting, horizontal moving, and lane stacking systems. In platform parking systems, the transporter needs to move the platform twice, both for parking and retrieval, which not only reduces the turnover rate of the automated parking system but also increases user waiting time.

[0003] To address this issue, existing technologies have proposed a dual-platform lifting transporter for vertical lift parking garages. This transporter has two levels of platform positions, one above the other, and a lifting and rotating platform located in the middle of the transporter supports the bottom of the platform, enabling the platform to be exchanged between the two positions.

[0004] However, in the above solutions, the lifting and rotating platform is designed to lift and rotate the platform and the vehicles on it. It has a large rated load, which results in a large size and weight. When it is extended to vertical lifting parking garages and non-vertical lifting parking garages that do not require vehicle rotation, it will greatly increase the weight and design difficulty of the transporter, and the manufacturing cost and operating energy consumption will be high. Summary of the Invention

[0005] In view of the above problems, the present invention proposes a vehicle platform exchange device, vehicle transporter, and automated parking system that at least partially solves the above problems. It aims to solve the problem that the existing double-vehicle platform lifting transporter is difficult to promote to vertical lifting automated parking systems and non-vertical lifting automated parking systems that do not require vehicle rotation. It abandons the technical solution of setting a lifting and rotating platform in the middle of the transporter, thereby reducing the weight and size of the vehicle platform exchange device, and achieving the effect of reducing the manufacturing cost and operating energy consumption of the vehicle platform exchange device.

[0006] Specifically, the present invention provides the following technical solution:

[0007] A pallet exchange device includes a first roller assembly and a second roller assembly. The first roller assembly includes a first set of rollers arranged horizontally. The second roller assembly is located below the first set of rollers. The second roller assembly includes a lifting mechanism and a second set of rollers arranged parallel to and spaced apart from the first set of rollers. The lifting mechanism is configured to drive the second set of rollers to move up and down, such that the second set of rollers has at least two height states: above the first set of rollers and below the first set of rollers. The first set of rollers and the second set of rollers are configured not to interfere with each other when moving towards each other in a vertical direction.

[0008] The first roller assembly further includes a avoidance mechanism, which is configured to drive the first roller assembly to avoid the vehicle platform when the second roller assembly supports the lifting and lowering movement of the vehicle platform.

[0009] Optionally, the first roller group includes a plurality of first rollers arranged along a straight line and spaced apart from each other. The second roller group includes a plurality of second rollers arranged along a straight line and spaced apart from each other.

[0010] On the horizontal projection plane, the first roller group and the second roller group are collinear, and the first roller and the second roller are staggered from left to right.

[0011] Optionally, the second roller device further includes a horizontally arranged second support frame, with all the second rollers rotatably connected to the same side of the second support frame.

[0012] The lifting mechanism is configured to drive the second support frame to lift.

[0013] Optionally, the first roller assembly further includes a horizontally arranged first support frame, with all the first rollers rotatably connected to the same side of the first support frame. On a horizontal projection plane, the first support frame and the second support frame are located on the front and rear sides of the first roller assembly, respectively.

[0014] The avoidance mechanism is configured to drive the first support frame to move back and forth.

[0015] Optionally, the avoidance mechanism is configured to drive the first support frame to rotate back and forth about a horizontal axis.

[0016] Optionally, the vehicle-mounted exchange device further includes a first drive mechanism and a second drive mechanism. The first drive mechanism includes a first motor and a first transmission assembly, wherein the first motor drives a plurality of first rollers to rotate synchronously via the first transmission assembly. The second drive mechanism includes a second motor and a second transmission assembly, wherein the second motor drives a plurality of second rollers to rotate synchronously via the second transmission assembly.

[0017] Optionally, the lifting mechanism is configured to drive the second roller group to at least three height states: higher than the first roller group; lower than the first roller group, with the height difference between the second roller group and the first roller group being a first preset height; and lower than the first roller group, with the height difference between the second roller group and the first roller group being a second preset height. The first preset height is not equal to the second preset height.

[0018] Optionally, the vehicle plate exchange device further includes a friction wheel assembly, which comprises a swing arm, a friction wheel, a third drive mechanism, and a fourth drive mechanism. The first end of the swing arm has a pivot extending about its front and rear. The friction wheel is rotatably connected to a second end of the swing arm away from the first end. The center plane of the friction wheel is coplanar with the center plane of a reference roller assembly. The reference roller assembly is either the first roller assembly or the second roller assembly.

[0019] The third drive mechanism is configured to drive the swing arm to rotate about the pivot at the first end, so that the friction wheel has at least the following two states:

[0020] When the second end moves upward into position, the friction wheel is horizontal with the reference roller group, and the friction wheel is outside the reference roller group.

[0021] When the second end moves downward into position, the friction wheel is lower than the reference roller group.

[0022] The fourth drive mechanism is configured to drive the friction wheel and the reference roller group to rotate synchronously when the friction wheel and the reference roller group are horizontal.

[0023] Optionally, the fourth drive mechanism includes a third transmission assembly configured to form a transmission connection between the reference roller assembly and the friction wheel.

[0024] Optionally, there are two friction wheel devices, located at the same end on the left and right sides of the first roller group and the second roller group, respectively.

[0025] Optionally, the friction wheel device consists of four wheels, located at the left and right ends of the first roller group and the left and right ends of the second roller group, respectively.

[0026] On the other hand, this application also provides a vehicle transporter, which includes a mobile vehicle platform and the aforementioned vehicle platform exchange device. The mobile vehicle platform is configured to have at least one of three movement modes: lifting, lateral movement, and longitudinal movement. There are two vehicle platform exchange devices, which are respectively arranged opposite to each other at the front and rear ends of the mobile vehicle platform.

[0027] On the other hand, this application also provides a multi-level parking garage, wherein the vehicle transporter includes multiple parking spaces, multiple vehicle platforms and at least one of the above-described vehicle transporters.

[0028] At least one of the parking spaces has two vehicle platforms arranged vertically, and the two vehicle platforms of the parking space are fixedly spaced at a vertical distance.

[0029] Optionally, at least one of the parking spaces has two vehicle platforms arranged vertically, and the vertical spacing between the two vehicle platforms in the parking space is adjustable.

[0030] Optionally, at least two of the parking spaces are provided with two vehicle platforms vertically. Furthermore, the vertical spacing between the two vehicle platforms in the two parking spaces is different.

[0031] This application provides a vehicle platform exchange device, comprising a first roller assembly and a second roller assembly arranged vertically. The first roller assembly supports a first vehicle platform position, and the second roller assembly supports a second vehicle platform position. The second roller assembly includes a lifting mechanism and a horizontally arranged second roller group. The lifting mechanism drives the second roller group to move up and down. When the second roller group supports the vehicle platform upwards, the vehicle platform can be exchanged from the second vehicle platform position to the first vehicle platform position. When the second roller group supports the vehicle platform downwards, the vehicle platform can be exchanged from the first vehicle platform position to the second vehicle platform position. Simultaneously, the first roller group and the second roller group are configured to not interfere with each other when moving towards each other in the vertical direction. Furthermore, the first roller assembly includes a clearance mechanism that drives the first roller group to avoid interference with the vehicle platform when the second roller group supports the vehicle platform's upward and downward movement. In other words, during the upward and downward movement of the second roller group, there is no interference between the first roller group and the second roller group, nor between the first roller group and the vehicle platform. The technical solution of this application, on the one hand, since the second roller group is only used for supporting and lifting the vehicle platform, the lifting mechanism can have a smaller rated load, that is, the lifting mechanism can have a smaller size and weight. On the other hand, the lifting mechanism directly drives the lifting motion of the second roller group, so that the vehicle platform exchange device can independently complete the vehicle platform exchange function without relying on the lifting and rotating platform set on the lifting transporter, which can be widely used in vehicle platform-type automated parking garages.

[0048] Figure 1 This is a schematic perspective view of a vehicle-to-vehicle exchange device according to an embodiment of the present invention, such as... Figure 1 As shown, and in combination Figure 2-10This invention provides a vehicle platform exchange device 1, including a first roller device 11 and a second roller device 12. The first roller device 11 includes a horizontally arranged first roller group 111. The second roller device 12 is located below the first roller group 111. The second roller device 12 includes a lifting mechanism 122 and a second roller group 121 arranged parallel to and spaced apart from the first roller group 111. The first roller group 111 and the second roller group 121 are configured to not interfere with each other when moving towards each other in the vertical direction. The lifting mechanism 122 is configured to drive the second roller group 121 to rise and fall, so that the second roller group 121 has at least two height states: above the first roller group 111 and below the first roller group 111. The first roller device 11 also includes a avoidance mechanism 112, which is configured to drive the first roller group 111 to avoid the vehicle platform 4 when the second roller group 121 supports the vehicle platform 4 in the rising and falling movement.

[0049] In this embodiment, the vehicle platform exchange device 1 is provided with a first roller device 11 and a second roller device 12 arranged vertically. The first roller device 11 can support and form a first vehicle platform position, and the second roller device 12 can support and form a second vehicle platform position. The first vehicle platform position is located directly above the second vehicle platform position. The first roller device 11 is provided with a first roller group 111, and the second roller device 12 is provided with a second roller group 121. Correspondingly, a first guide rail and a second guide rail, corresponding to the first roller group 111 and the second roller group 121, can be provided on the vehicle platform 4, so that the first roller group 111 drives the first guide rail to move the vehicle platform 4 horizontally, and the second roller group 121 drives the second guide rail to move the vehicle platform 4 horizontally. The first guide rail and / or the second guide rail can be provided on the lower side of the vehicle platform 4, or on the front and rear ends of the vehicle platform 4, without limitation. When the first guide rail and / or the second guide rail are provided on the lower side of the vehicle platform 4, they can be configured as a V-shape, groove shape, etc., with the opening facing downwards. When the first guide rail and / or the second guide rail are located at the front and rear ends of the vehicle plate 4, they can be configured as a cross-section with the opening facing outwards, etc.

[0050] In this application, the horizontal movement direction of the vehicle platform 4 is described as left and right, and the first guide rail and / or the second guide rail are both parallel to the horizontal movement direction of the vehicle platform 4. The direction perpendicular to the horizontal movement of the vehicle platform 4 is described as front and back. For example, when the vehicle platform 4 moves horizontally laterally, the two ends of the length of the vehicle platform 4 are the front and rear ends. For example, when the vehicle platform 4 moves horizontally longitudinally, the two ends of the width of the vehicle platform 4 are the front and rear ends.

[0051] It should be understood that the second roller group 121 can be located directly below the first roller group 111. In this case, the first guide rail and the second guide rail are the same guide rail. The second roller group 121 can also be located to the side and below the first roller group 111, such as behind and below. In this case, the first guide rail and the second guide rail are two guide rails arranged at a front-to-back interval.

[0052] In this embodiment, a lifting mechanism 122 is provided in the second roller device 12. The lifting mechanism 122 can be a motor, push rod, hydraulic system, etc., and can drive the second roller group 121 to rise and fall. Meanwhile, the first roller group 111 and the second roller group 121 are configured so as not to interfere with each other when moving towards each other in the vertical direction. For example, when the second roller group 121 is located to the side and below the first roller group 111, the lifting mechanism 122 can directly drive the second roller group 121 to rise and fall without worrying about interference between the second roller group 121 and the first roller group 111 when moving towards each other in the vertical direction. For example, when the second roller group 121 is directly below the first roller group 111, the second roller group 121 can be staggered with the first roller group 111 so that when the lifting mechanism 122 drives the second roller group 121 to rise and fall, the second roller group 121 will not interfere with the first roller group 111.

[0053] In this embodiment, an avoidance mechanism 112 is provided in the first roller device 11. When the second roller group 121 supports the lifting and lowering movement of the vehicle platform 4, the avoidance mechanism 112 drives the first roller group 111 to avoid the vehicle platform 4. Since the first vehicle platform position and the second vehicle platform position coincide on the horizontal projection plane, when the vehicle platform 4 is raised from the second vehicle platform position to the first vehicle platform position, or when the vehicle platform 4 is lowered from the first vehicle platform position to the second vehicle platform position, the first roller group 111 will interfere with the vehicle platform 4. The avoidance mechanism 112 is used to solve this problem. Exemplarily, the avoidance mechanism 112 can drive the first roller group 111 to move back and forth; exemplarily, the avoidance mechanism 112 can drive the first roller group 111 to rotate back and forth around the horizontal axis. In this way, when the second roller group 121 supports the lifting and lowering movement of the vehicle platform 4, the first roller group 111 can avoid the vehicle platform 4 without interference.

[0054] It should be noted that the heights of the first roller group 111 and the second roller group 121 described in this application indicate the height of the support surface of the support plate 4 of the roller group.

[0055] In this embodiment, in actual use, such as Figure 7 As shown, when exchanging platform 4 from the second platform position to the first platform position, for example, the avoidance mechanism 112 first drives the first roller group 111 to perform an avoidance action, moving from the initial position to the avoidance position. The lifting mechanism 122 then drives the second roller group 121, which supports and fixes the platform 4, to rise. The second roller group 121 rises to a height slightly higher than the height before the first roller group 111 performed the avoidance action. The avoidance mechanism 112 then drives the first roller group 111 back to its initial position. Then, the lifting mechanism 122 drives the second roller group 121 to descend. During the descent, the platform 4 is supported and fixed by the first roller group 111, while the second roller group 121 continues to descend to the height of the second platform position. In this way, the exchange of platform 4 is completed.

[0056] When exchanging platform 4 from the first platform position to the second platform position, the lifting mechanism 122 drives the second roller group 121 to rise. Passing the first roller group 111, the second roller group 121 supports and fixes platform 4, and continues to rise a certain distance. The avoidance mechanism 112 first drives the first roller group 111 to perform an avoidance action, moving from the initial position to the avoidance position. Then, the lifting mechanism 122 drives the second roller group 121, which supports and fixes platform 4, to descend to the height of the second platform position. Finally, the avoidance mechanism 112 drives the first roller group 111 to return to its initial position. In this way, the exchange of platform 4's position is completed.

[0057] The technical solution of this application, on the one hand, since the second roller group 121 is only used to support and lift the vehicle platform 4, the lifting mechanism 122 can have a smaller rated load, that is, the lifting mechanism 122 can have a smaller size and weight. On the other hand, the lifting mechanism 122 directly drives the lifting movement of the second roller group 121, so that the vehicle platform exchange device 1 can independently complete the vehicle platform 4 exchange function without the need for a lifting and rotating platform set on the lifting transporter, which can be widely used in vehicle platform 4-type automated parking garages.

[0058] In particular, such as Figure 5-6 As shown, Figure 5-6 The diagram illustrates two heights, H1 and H2, of the second roller group 121 relative to the first roller group 111. Since the height of the second roller group 121 relative to the first roller group 111 in this embodiment is achieved by the lifting mechanism 122, the height value of the second roller group 121 relative to the first roller group 111 can be easily adjusted by adjusting the lifting mechanism 122. This makes the vehicle platform exchange device 1 of this application highly applicable and versatile. Different types of automated parking garages with double vehicle platforms 4, or automated parking garages with double vehicle platforms 4 from different manufacturers, have vastly different vertical spacing between the double vehicle platforms 4. When selecting the vehicle platform exchange device 1, customization is required for each different situation. The vehicle platform exchange device 1 of this application does not require customization; it can be directly applied simply by adjusting the lifting parameters of the lifting mechanism 122.

[0059] In some embodiments of the vehicle-to-vehicle exchange device of the present invention, such as Figure 4 As shown, the first roller group 111 includes a plurality of first rollers 1111 arranged along a straight line and spaced apart from left to right. The second roller group 121 includes a plurality of second rollers 1211 arranged along a straight line and spaced apart from left to right. On the horizontal projection plane, the first roller group 111 and the second roller group 121 are collinear, and the first rollers 1111 and the second rollers 1211 are arranged alternately from left to right.

[0060] In this embodiment, the center plane of the first roller group 111 and the center plane of the second roller group 121 are coplanar. Therefore, only one guide rail needs to be provided at the corresponding position on the vehicle platform 4; or, the first guide rail and the second guide rail on the vehicle platform 4 are the same guide rail. This simplifies the overall structure and space occupation of the vehicle platform exchange device 1, and also simplifies the overall structure and space occupation of the vehicle platform 4 that matches the vehicle platform exchange device 1. Simultaneously, to avoid interference when the first roller 1111 and the second roller 1211 move towards each other in the vertical direction, the first roller 1111 and the second roller 1211 are arranged alternately along the horizontal projection plane. For example, the first roller group 111 can have 5 first rollers 1111 spaced apart along the left and right, and the second roller group 121 can have 4 second rollers 1211 spaced apart along the left and right. On the horizontal projection plane, the first rollers 1111 and the second rollers 1211 are arranged sequentially. It should be understood that the first roller group 111 can be set with M first rollers 1111, and the second roller group 121 can be set with N second rollers 1211. N and M can be equal or unequal, as long as the projections of the M first rollers 1111 and the N second rollers 1211 on the horizontal projection plane do not overlap or interfere.

[0061] In this embodiment, the first roller 1111 and the second roller 1211 can be made of metal, plastic, polyurethane, composite materials, etc., and there is no limitation. It should be noted that the first roller 1111 and the second roller 1211 can have the same specifications and dimensions, or use the same rollers. This allows for unified design and manufacturing, and the use of the same standard parts when assembling into the vehicle platform exchange device 1, thereby reducing production and maintenance costs. Of course, the first roller 1111 and the second roller 1211 can also have different specifications and dimensions. In particular, since the first roller 1111 has two rated loads, one for the vehicle platform 4 and the other for the vehicle platform 4 and the vehicle, the first roller 1111 should have a larger specification and size. The second roller 1211 only needs to support and fix the vehicle platform 4 and does not need to bear the weight of the vehicle. Therefore, the second roller 1211 can be set to a smaller specification and size than the first roller 1111, to further save space in the second roller assembly 121 and reduce production and maintenance costs.

[0062] In some embodiments of the vehicle-to-vehicle exchange device of the present invention, such as Figure 1-4 As shown, the second roller device 12 also includes a horizontally arranged second support frame 123, with all the second rollers 1211 rotatably connected to the same side of the second support frame 123. The lifting mechanism 122 is configured to drive the second support frame 123 to rise and fall.

[0063] In this embodiment, all the second rollers 1211 are rotatably connected to the same side of the second support frame 123. This facilitates the arrangement of the second rollers 1211, ensuring that the centers of all the second rollers 1211 are collinear, and also facilitates the arrangement of a drive or transmission device to drive the second rollers 1211 to rotate synchronously. Furthermore, the lifting mechanism 122 only needs to be fixedly connected to the second support frame 123; driving the second support frame 123 to rise and fall will drive all the second rollers 1211 to rise and fall synchronously, simplifying the structure of the lifting mechanism 122.

[0064] In some embodiments of the vehicle-to-vehicle exchange device of the present invention, such as Figure 1-4 As shown, the first roller assembly 11 also includes a horizontally arranged first support frame 113, with all the first rollers 1111 rotatably connected to the same side of the first support frame 113. On the horizontal projection plane, the first support frame 113 and the second support frame 123 are located on the front and rear sides of the first roller assembly 111, respectively. A clearance mechanism 112 is configured to drive the first support frame 113 to move back and forth (not shown in the figure).

[0065] In this embodiment, all the first rollers 1111 are rotatably connected to the same side of the first support frame 113. This facilitates the arrangement of the first rollers 1111, ensuring that the centers of all the first rollers 1111 are collinear, and also facilitates the arrangement of a drive or transmission device to drive the first rollers 1111 to rotate synchronously. Furthermore, the avoidance mechanism 112 only needs to be connected to the first support frame 113; driving the first support frame 113 to move back and forth will drive all the first rollers 1111 to move back and forth, thus avoiding interference with the vehicle platform 4. The avoidance mechanism 112 can be equipped with a motor, push rod, hydraulic system, etc., to achieve the pushing and pulling action of the first support frame 113, which will not be elaborated here.

[0066] In this embodiment, on the horizontal projection plane, the first support frame 113 and the second support frame 123 are located on the front and rear sides of the first roller assembly 111, respectively. Thus, when the second support frame 123 drives the second roller 1211 to move up and down, the first support frame 113 and the second support frame 123 will not interfere with each other.

[0067] In some embodiments of the vehicle-to-vehicle exchange device of the present invention, such as Figure 7 As shown, the avoidance mechanism 112 is configured to drive the first support frame 113 to rotate back and forth around a horizontal axis.

[0068] The difference between this embodiment and the previous embodiment is that the avoidance mechanism 112 drives the first support frame 113 to rotate back and forth around the horizontal pivot to avoid the lifting platform 4. The avoidance mechanism 112 may be equipped with a motor, push rod, hydraulic system, etc., to realize the back and forth rotation action of the first support frame 113, which will not be described in detail here.

[0069] In some embodiments of the vehicle-to-vehicle exchange device of the present invention, such as Figure 1-2 As shown, the vehicle-to-vehicle exchange device 1 also includes a first drive mechanism 13 and a second drive mechanism 14. The first drive mechanism 13 includes a first motor 131 and a first transmission assembly 132. The first motor 131 drives a plurality of first rollers 1111 to rotate synchronously through the first transmission assembly 132. The second drive mechanism 14 includes a second motor 141 and a second transmission assembly 142. The second motor 141 drives a plurality of second rollers 1211 to rotate synchronously through the second transmission assembly 142.

[0070] In this embodiment, the first transmission component 132 may include a sprocket and chain combination, or a pulley and conveyor belt combination, or a gear and rack combination, for forming a transmission connection between the first motor 131 and the plurality of first rollers 1111, so that the plurality of first rollers 1111 rotate synchronously. Thus, only one first motor 131 can be used to simultaneously drive the plurality of first rollers 1111 to rotate synchronously. Similarly, the second transmission component 142 may include a sprocket and chain combination, or a pulley and conveyor belt combination, or a gear and rack combination, for forming a transmission connection between the second motor 141 and the plurality of second rollers 1211, so that the plurality of second rollers 1211 rotate synchronously.

[0071] It should be noted that the first motor 131 can drive all the first rollers 1111 to rotate synchronously via the first transmission assembly 132, meaning that all the first rollers 1111 become driving wheels. The first motor 131 can also drive some of the first rollers 1111 to rotate synchronously via the first transmission assembly 132, meaning that some of the first rollers 1111 are driving wheels, while others are driven wheels. This can be configured as needed in actual use. Similarly, the second motor 141 and the second transmission assembly 142 can be configured similarly.

[0072] In some embodiments of the vehicle-to-vehicle exchange device of the present invention, such as Figure 5-6 As shown, the lifting mechanism 122 is configured to drive the second roller group 121 to have at least three height states: higher than the first roller group 111; lower than the first roller group 111, and the height difference between the second roller group 121 and the first roller group 111 is a first preset height H1; lower than the first roller group 111, and the height difference between the second roller group 121 and the first roller group 111 is a second preset height H2. The first preset height is not equal to the second preset height.

[0073] In this embodiment, in the second vehicle platform position state, the second roller group 121 has a first preset height and a second preset height, that is, the vertical spacing between the second vehicle platform position and the first vehicle platform position can have two types.

[0074] Those skilled in the art will understand that multi-level parking garages typically require two or more different types of parking spaces 5 to accommodate vehicles of different sizes. For example, there may be parking spaces 5 for different sizes and weights, or parking spaces 5 with and without charging devices for electric vehicles. An example is provided below:

[0075] A multi-level parking garage has two types of parking spaces 5. One type is non-charging, used for storing fuel-powered vehicles or electric vehicles that do not require charging. Since no charging device is needed, the platform 4 of the non-charging parking space 5 can be made thinner. The other type is charging, used for vehicles that require charging. Because charging devices such as charging interfaces, transformer modules, and control modules are needed, the platform 4 is thicker and occupies more space. In other words, when a multi-level parking garage has both non-charging and charging parking spaces 5, the vertical spacing between the two platforms 4 at each type of parking space 5 is different. The spacing between the two platforms 4 in the non-charging parking space 5 is smaller, while the spacing between the two platforms 4 in the charging parking space 5 is larger. In the prior art, the vertical spacing between the first roller group 111 and the second roller group 121 of the vehicle platform exchange device 1 is fixed. Only one type of parking space 5 can be selected, such as a non-charging parking space 5, so that the spacing between the first roller group 111 and the second roller group 121 matches the spacing between the two vehicle platforms 4 of the non-charging parking space 5. This allows for simultaneous operation of both vehicle platforms 4 when storing or retrieving them from the non-charging parking space 5. However, when storing or retrieving vehicle platforms 4 from the charging parking space 5, the vehicle platform exchange device 1 cannot operate simultaneously. It can only store or retrieve one vehicle platform 4 first, for example, the upper vehicle platform 4, and then perform a lifting and lowering operation on the entire vehicle platform exchange device 1 to store or retrieve the lower vehicle platform 4. This increases the operation time and the user's waiting time.

[0076] In this embodiment, by having the second roller assembly 121 have a first preset height and a second preset height, when facing a parking space 5 with similar car platform 4 having two different spacings, simply by matching the first preset height and the second preset height with the two different spacings of the car platform 4, it is possible to simultaneously store and retrieve two car platforms 4. This greatly saves operation time and user waiting time.

[0077] In particular, in this embodiment, the second roller group 121 may also have other heights different from the three heights mentioned above, so that the vertical spacing between the second car platform position and the first car platform position has three or more types, in order to cope with parking spaces 5 with three or more car platform 4 spacings.

[0078] In some embodiments of the vehicle-to-vehicle exchange device of the present invention, such as Figure 2-4As shown, the vehicle plate exchange device 1 also includes a friction wheel device 15, which includes a swing arm 151, a friction wheel 152, a third drive mechanism 153, and a fourth drive mechanism 154. The first end 1511 of the swing arm 151 has a pivot extending about a longitudinal axis. The friction wheel 152 is rotatably connected to a second end 1512 of the swing arm 151, away from the first end 1511. The center plane of the friction wheel 152 is coplanar with the center plane of a reference roller assembly. The reference roller assembly is either a first roller assembly 111 or a second roller assembly 121. The third drive mechanism 153 is configured to drive the swing arm 151 to rotate about the pivot of the first end 1511, so that the friction wheel 152 has at least two of the following states:

[0079] When the second end 1512 moves upward to its position, the friction wheel 152 is horizontal with the reference roller group, and the friction wheel 152 is outside the reference roller group.

[0080] When the second end 1512 moves downward into position, the friction wheel 152 is lower than the reference roller group.

[0081] The fourth drive mechanism 154 is configured to drive the friction wheel 152 and the reference roller group to rotate synchronously when the friction wheel 152 is horizontal with the reference roller group.

[0082] Since the pallet exchange device 1 moves with the vehicle transporter 3 between multiple parking spaces 5, a certain gap will remain between the first or second pallet position and the parking space 5. In the prior art, a drive mechanism is usually installed on the parking space 5. When the pallet 4 is in the parking space 5, the drive mechanism drives the pallet 4 to move horizontally toward the pallet exchange device 1 until the pallet 4 contacts the first roller group 111 or the second roller group 121 of the pallet exchange device 1. Then, the first roller group 111 or the second roller group 121 drives the pallet 4 to continue moving horizontally to the first or second pallet position.

[0083] In this embodiment, the third drive mechanism 153 may include a motor, push rod, hydraulic system, etc., for driving the swing arm 151 to swing. The friction wheel device 15 is used to drive the vehicle platform 4 located in the parking space 5, so that the vehicle platform 4 moves horizontally to the first or second vehicle platform position of the vehicle platform exchange device 1. The friction wheel device 15 is also used to drive the vehicle platform 4 located in the first or second vehicle platform position of the vehicle platform exchange device 1, so that the vehicle platform 4 moves horizontally to the parking space 5. That is to say, by setting the friction wheel device 15, it is not necessary to set a drive mechanism in each parking space 5, which can greatly save manufacturing costs.

[0084] For example, when retrieving the upper platform 4 of parking space 5, the reference roller group is the first roller group 111. First, ensure that the second end 1512 of the swing arm 151 moves downward into position, preventing the friction wheel 152 from extending to the left or right side to avoid interference between the friction wheel 152 and parking space 5. The platform exchange device 1 moves to the vicinity of the left side of parking space 5, making the first roller group 111 horizontal with the upper platform 4 of parking space 5. The third drive mechanism 153 of the friction wheel device 15 on the right side of the platform exchange device 1 drives the swing arm 151 to swing upward and to the right a certain distance. At this time, the friction wheel 152 moves upward to be horizontal with the first roller group 111 and moves to the right to the lower side of the platform 4, contacting the first guide rail of the platform 4 to form friction. Then, the fourth drive mechanism 154 drives the friction wheel 152 to rotate, moving the platform 4 towards the platform exchange device 1. Simultaneously, the first drive mechanism 13 drives the first roller group 111 to rotate in the same direction. After the first guide rail of the vehicle platform 4 contacts the roller, the vehicle platform 4 continues to move horizontally to the first vehicle platform position and then stops rotating. In this way, the vehicle platform 4 is transferred from the parking space 5 to the vehicle platform exchange device 1.

[0085] In some embodiments of the vehicle-to-vehicle exchange device of the present invention, such as Figure 4 As shown, the fourth drive mechanism 154 includes a third transmission assembly configured to form a transmission connection between the reference roller assembly and the friction wheel 152.

[0086] In this embodiment, the fourth drive mechanism 154 does not have a motor or other power mechanism. Instead, it connects the power transmission of the reference roller group to the friction wheel 152 through a third transmission component, enabling the friction wheel 152 to rotate synchronously with the reference roller group. The third transmission component can be a combination of sprockets and chains, or a combination of pulleys and conveyor belts. For example, the third transmission component can be a combination of sprockets and chains. The pivot of the first end 1511 of the swing arm 151 is coaxial with one of the rollers of the reference roller group, and a sprocket is coaxially and fixedly connected to this roller. The friction wheel 152 is also coaxially and fixedly connected to a sprocket, and the chain is wound around the sprocket of the roller and the sprocket of the friction wheel 152. In this way, the friction wheel 152 utilizes the power of the reference roller group, and even if the swing arm 151 swings under the drive of the third drive mechanism 153, it will not disengage from the transmission connection between the friction wheel 152 and the reference roller group.

[0087] In some embodiments of the plate exchange device of the present invention, there are two friction wheel devices 15, which are respectively located at the same end on the left and right sides of the first roller group 111 and the second roller group 121.

[0088] In this embodiment, the vehicle platform exchange device 1 can be used to store and retrieve vehicle platforms 4 located in parking spaces 5 on one side of it. For example, the vehicle platform exchange device 1 can be used to store and retrieve vehicle platforms 4 located in parking spaces 5 on its left side. In this case, friction wheel devices 15 are provided on the left side of both the first roller group 111 and the second roller group 121. That is, two friction wheel devices 15 are arranged vertically, and the reference roller groups for the two friction wheel devices 15 are the first roller group 111 and the second roller group 121, respectively. When retrieving a vehicle platform 4, the friction wheels 152 of both friction wheel devices 15 extend upwards and to the left, driving the two vehicle platforms 4 in one parking space 5 to move horizontally toward the vehicle platform exchange device 1. Alternatively, when retrieving and returning the vehicle to platform 4, the friction wheels 152 of both friction wheel devices 15 extend to the upper left. The upper friction wheel device 15 drives the upper platform 4 of a parking space 5 and the vehicle on the platform 4 to move horizontally towards the platform exchange device 1, while the lower friction wheel device 15 drives the platform 4 of the platform exchange device 1 located in the second platform position to move horizontally towards the empty space below the parking space 5. The vehicle retrieval and return platform 4 operations are completed simultaneously.

[0089] In some embodiments of the vehicle-to-vehicle exchange device of the present invention, such as Figure 2-4 As shown, there are four friction wheel devices 15, which are located at the left and right ends of the first roller group 111 and the left and right ends of the second roller group 121, respectively.

[0090] In this embodiment, the vehicle platform exchange device 1 can be used to store and retrieve vehicle platforms 4 located in the parking spaces 5 on the left and right sides.

[0091] In some embodiments of the vehicle transporter 3 of the present invention, such as Figure 9-10 As shown, the vehicle transporter 3 includes a mobile platform 2 and the aforementioned vehicle platform exchange device 1. The mobile platform 2 is configured to have at least one of three movement modes: lifting, lateral movement, and longitudinal movement. There are two vehicle platform exchange devices 1, which are respectively arranged opposite each other at the front and rear ends of the mobile platform 2.

[0092] In this embodiment, the mobile vehicle platform 2 can be a lifting transporter for lifting and transporting; it can also be a rail transporter for horizontal transporting; it can also be a tunnel transporter for both lifting and horizontal transporting; or it can be an AGV, etc. Since the vehicle platform exchange device 1 can independently complete the operation of exchanging two vehicle platforms 4, and its size and weight are small, it can be easily applied to various mobile vehicle platforms 2, enabling the vehicle transporter 3 to realize the function of exchanging two vehicle platforms 4.

[0093] In some embodiments of the automated parking system of the present invention, the automated parking system includes a plurality of parking spaces 5, a plurality of vehicle platforms 4, and at least one of the aforementioned vehicle transporters 3. At least one parking space 5 has two vehicle platforms 4 arranged vertically.

[0094] In this embodiment, the automated parking garage can be a vertical lifting type with a platform 4, a planar moving type with a platform 4, or a lane stacking type with a platform 4, etc. In this automated parking garage, all or some of the parking spaces 5 have double platforms 4.

[0095] In some embodiments of the three-dimensional parking garage of the present invention, the two car platforms 4 of the parking space 5 are fixedly arranged at a vertical distance.

[0096] In this embodiment, since the two car platforms 4 of the parking space 5 are fixedly spaced along the vertical direction, only the parameters of the lifting mechanism 122 need to be adjusted once to apply it to the overall three-dimensional parking garage.

[0097] In some embodiments of the automated parking system of the present invention, the vertical spacing between the two car platforms 4 of at least one parking space 5 is adjustable.

[0098] In this embodiment, when the vertical spacing between the two car platforms 4 of some parking spaces 5 in the automated parking garage is adjusted to accommodate different vehicles, it is only necessary to mark these parking spaces 5 and pre-store them in the operating program. Before storing or retrieving the car platforms 4 in these parking spaces 5, the car platform exchange device 1 of the vehicle transporter 3 automatically adjusts the parameters of the lifting mechanism 122 to adapt to the car platforms 4 of these parking spaces 5. In other words, one vehicle transporter 3 can handle parking spaces 5 of two or more types.

[0099] In some embodiments of the automated parking garage of the present invention, the automated parking garage includes multiple parking spaces 5, multiple vehicle platforms 4, and at least one of the aforementioned movable vehicle platforms 2. At least two parking spaces 5 have two vehicle platforms 4 arranged vertically. Furthermore, the vertical spacing between the two vehicle platforms 4 of the two parking spaces 5 is different.

[0100] In this embodiment, when the vertical spacing of the two car platforms 4 in some parking spaces 5 of the automated parking garage is different to accommodate different types of vehicles, it is only necessary to mark these parking spaces 5 and pre-store them in the operating program. Before storing or retrieving the car platforms 4 in these parking spaces 5, the car platform exchange device 1 of the vehicle transporter 3 automatically adjusts the parameters of the lifting mechanism 122 to adapt to the car platforms 4 of these parking spaces 5. In other words, one vehicle transporter 3 can handle parking spaces 5 of two or more types.

[0101] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
