Description

TECHNICAL FIELD

[0001] The present application belongs to the field of mechanized parking, and relates to a parking garage for public bicycles, in particular to a circumferential multi-layer horizontal arrangement public bicycle garage capable of arranging public bicycles in a circumferential manner and parking them horizontally above the ground to reduce the occupied area. BACKGROUND

[0002] With the operation of public bicycles, the phenomenon of uneven distribution of parking points, no available bicycles or no place to return the bicycles occurs from time to time, which hinders the further promotion of public bicycles to some extent. At present, most public bicycle parking points adopt the parking mode of fixed piles along the sidewalk or electronic fences. However, since both of them are ground single-row parking modes, if too many are distributed, the parking points will inevitably occupy a long road surface resource, especially in the areas with dense flow of people and strong demand for public bicycles, such as stations, commercial centers and scenic spots. At present, the ground single-row parking mode has shown great limitations. Therefore, if there is a mechanical three-dimensional public bicycle parking garage without occupying a long road surface resource and with a large capacity, the parking garage can be set on the limited open space in the areas with dense flow of people, such as stations, commercial centers and scenic spots. In combination with the fixed pile type or electronic fence type ground single-row parking points suitable for the sidewalk at present, the use of public bicycles will be more convenient and extensive.

[0003] At present, some people have proposed a cylindrical mechanical bicycle parking garage, such as patent document 1 (CN106930572A), patent document 2 (CN109235952A) and patent document 3 (CN212201481U). Among them, patent document 1 discloses that the multi-layer parking platform of the parking garage is located underground, the fixed parking spaces on each platform are arranged in a ring array, the center of the cylindrical parking garage has a center shaft, the center shaft is provided with a center frame capable of lifting, the center frame is provided with a straight sliding mechanical arm for clamping and pulling the bicycle; patent document 2 discloses that the parking garage is composed of a plurality of storage frames arranged in sequence along a circumferential line to form the outer frame of the cylindrical parking garage, a double-column mounting frame capable of rotating is arranged at the center of the frame, a load platform capable of lifting in the vertical direction is arranged between the double columns of the mounting frame, and a clamping mechanism and a sliding mechanism capable of pulling the bicycle at the entrance of the bottom layer of the garage to the load platform are arranged on the load platform; patent document 3 discloses that a plurality of parking frames arranged in a circumferential manner form the circular main body of the parking garage, a garage center column capable of rotating is arranged at the center of the garage, a clamping mechanism and a sliding mechanism are arranged on the load mechanism capable of lifting along the garage center column, the bicycle is clamped by the clamping mechanism and then lifted by the load mechanism, rotated to the guide groove of the corresponding parking frame, and then pushed into the guide groove of the bicycle parking frame by the sliding mechanism on the load mechanism to realize the aerial parking, and the load mechanism is radially arranged around the garage center column.

[0004] As can be seen from patent documents 1, 2 and 3, the existing cylindrical mechanical bicycle parking garage is to horizontally drag the bicycle outside the garage to the loading platform after clamping by the clamping device on the loading platform in the flat standing state during use, and then vertically lift and horizontally rotate around the central axis by the loading platform, and then send the bicycle to the parking frame distributed radially on the outer periphery by the pushing mechanism on the loading platform. When the bicycle is parked on the outer frame and rotated on the loading platform, the bicycle is in a flat standing state and the length direction is in the radial direction of the garage circumference. Such design requires sufficient space between the parking frame on the outer periphery of the garage and the middle of the garage, and also requires sufficient height of each layer of parking frame, which will cause the disadvantages of large diameter and large land occupation of the cylindrical parking garage.

Adjacent main columns 12 and adjacent parking columns 11 are fixedly connected to each other by corresponding vertically spaced connectors. One column group (i.e., the front) forms a doorway for the fixed enclosure 1 without connectors at a predetermined height above the ground, used for public bicycles to enter and exit the fixed enclosure 1. In the 3 column groups that do not include doorways, two vertical racks 14 are fixedly installed in 2 of them, i.e., the rear and left column groups are fixedly installed in the rear column group and the left column group respectively. Each vertical rack 14 is fixedly connected to the inner surface of a corresponding connector (i.e., a connecting beam 16). Figure 2 As shown in partial view J2; in each column group, each vertical rack 14 is also fixedly installed with a corresponding guide rail 13 on both sides. The vertical rack 14 and all the guide rails 13 together form a guide rack group. Each guide rack group is slidably connected to the central storage and retrieval transport vehicle 2. Specifically, each vertical rack 14 meshes with the lifting drive gear 244 of the lifting drive motor 24 to form a first gear rack pair. A corresponding support truss 23 is slidably installed in the guide rail 13. Several sets of vertically spaced support brackets are fixedly installed at each parking column 11 and its connecting parts. That is, multiple sets of support brackets are arranged in layers along the parking column 11, and the number of layers can be determined according to specific needs. One public bicycle can be placed at each support bracket, such as...

Since the reversing gear 217 meshes with the internal gear ring on the inner half-ring seat 212, and the reversing gear 217 is hinged to the sliding rod 218, the pitch circle of the reversing gear 217 rolls purely within the pitch circle of the internal gear ring on the inner half-ring seat 212. Therefore, while rotating on its own axis, the reversing gear 217 also rotates around the inner half-ring seat 212. The center of the ring seat 212 revolves around the sun, and the direction of rotation of the reversing gear 217 is opposite to the direction of the revolution. The reversing main shaft 21B is perpendicularly inserted through the middle of the sliding rod 218.

[0044] The pitch circle radius of the internal gear ring on the inner half-ring seat 212 is 4 times that of the pitch circle radius of the reversing gear 217. Thus, while the reversing gear 217 rotates four times, it also revolves once around the center of the inner half-ring seat 212. Therefore, while the reversing gear 217 rotates 360 degrees in one direction, it also revolves 90 degrees in the opposite direction around the center of the inner half-ring seat 212.

The outer carrier frame 2261, the middle carrier frame 2264 and the inner carrier frame 2265 are all long strip structures with a "U" shaped section with the opening upward. When the public bicycle is taken from or put on the fixed enclosure 1, the opening direction is the same as the direction of the first shaft extension, so that the public bicycle lies flat in the direction of the inner wall of the fixed enclosure 1. The inner carrier frame 2265 is contained in the cavity of the middle carrier frame 2264 and is connected with the middle carrier frame 2264 in sliding mode, and the middle carrier frame 2264 is contained in the cavity of the outer carrier frame 2261 and is connected with the middle carrier frame 2264 in sliding mode.

[0051] As Figure 8As shown, the seat tube supporting hook 22C includes a supporting outer seat 22C1, a guide sleeve 22C2, a screw hook 22C3, a nut 22C4, a nut driving slave gear 22C5, a nut driving master gear 22C6, a seventh driving motor 22C7 and a roller 22C8; in combination Figure 6 In the middle part view J1 and Figure 11 As shown in step ④, the supporting outer seat 22C1 has an end plate protruding from one end and the rest of the body is a cylindrical structure, the supporting outer seat 22C1 is fixed to the side surface of the one end of the second shaft extension of the rotating rod 228, that is, the axis of the cylindrical body of the supporting outer seat 22C1 protruding branch top is parallel to the axis of the second shaft extension of the rotating rod 228, the one end of the supporting outer seat 22C1 with the end plate faces the telescopic car frame 226; The supporting outer seat 22C1 coaxially fixedly nests the guide sleeve 22C2, the nut 22C4 is arranged in one end of the supporting outer seat 22C1, that is, the nut 22C4 is sleeved in the abdomen of the one end of the supporting outer seat 22C1 with the end plate and can rotate in the supporting outer seat 22C1, the seventh driving motor 22C7 is fixedly installed outside the one end of the supporting outer seat 22C1 where the nut 22C4 is located, the nut driving slave gear 22C5 is arranged at the outer end surface of the one end of the supporting outer seat 22C1 where the nut 22C4 is located, the nut driving slave gear (22C5) is fixedly connected with the nut (22C4), specifically, the seventh driving motor 22C7 is parallel to the cylindrical body of the supporting outer seat 22C1 and is fixedly installed on the outer end surface of the protruding end plate of the supporting outer seat 22C1. The nut driving slave gear 22C5 is coaxially arranged with the supporting outer seat 22C1, the guide sleeve 22C2 and the nut 22C4, the output shaft of the seventh driving motor 22C7 is parallel to the axial direction of the nut 22C4, the output shaft of the seventh driving motor 22C7 is coaxially fixedly connected with the nut driving master gear 22C6, the nut driving master gear 22C6 is engaged with the nut driving slave gear 22C5 to form the sixth gear pair, so that the seventh driving motor 22C7 can drive the nut driving master gear 22C6 and the nut driving slave gear 22C5 to rotate, the nut driving slave gear 22C5 drives the nut 22C4 fixedly connected therewith to rotate, thereby driving the screw hook 22C3 to move.

[0052] As Figure 8 As shown by the dashed line in the upper left corner of the figure, an arc-shaped groove and an axial groove are formed at the circumferential side surface of the guide sleeve 22C2, the arc-shaped groove is arranged at the one end of the guide sleeve 22C2 close to the nut 22C4, one end of the arc-shaped groove communicates with the one end of the axial groove close to the nut 22C4 and together forms a guide groove; the main body of the screw hook 22C3 is a left-handed screw rod, the one end of the screw hook 22C3 is arranged in a hook shape for fixing the seat tube; the circumferential side surface of the other end of the screw hook 22C3 is provided with a protruding shaft, the protruding shaft is arranged perpendicular to the threaded shaft of the screw hook 22C3, as Figure 8As shown in the upper right corner figure, a roller 22C8 is coaxially mounted on the protruding shaft. The end of the screw hook 22C3 with the roller 22C8 passes through the nut, drive gear 22C5, one end face of the outer support 22C1, and nut 22C4 in sequence, and is then placed in the guide sleeve 22C2. The roller 22C8 is embedded in the guide groove. The screw hook 22C3 and the nut 22C4 are connected by threads. The roller 22C8 rotates counterclockwise through a certain angle in the arc groove before entering the axial groove. When the roller 22C8 is in the axial groove on the guide sleeve 22C2, it guides the screw hook 22C3. The axial linear motion is hindered by the sidewall of the axial groove, which obstructs the rotation of roller 22C8 and screw hook 22C3. The rotation of nut 22C4 can only drive screw hook 22C3 to move axially. Since the main body of screw hook 22C3 has a left-hand thread, when viewed from the end face of the cylindrical body of the outer support 22C1 towards the guide sleeve 22C2, the counterclockwise rotation of nut 22C4 can drive screw hook 22C3 to retract. When roller 22C8 is in the arc-shaped groove on guide sleeve 22C2, it guides screw hook 22C3 to rotate 90 degrees. This is because the sidewall of the arc-shaped groove... The axial movement of roller 22C8 and screw hook 22C3 is hindered, and the rotation of nut 22C4 can only drive screw hook 22C3 to rotate in the same direction as it. As can be seen from the above, looking at the guide sleeve 22C2 from the end face of the cylindrical body supporting outer seat 22C1, when roller 22C8 is located at the other end of the arc groove away from the axial groove, the seventh drive motor 22C7 drives nut 22C4 to rotate counterclockwise, which can first drive screw hook 22C3 to rotate 90 degrees counterclockwise along the arc groove, so that the hook on screw hook 22C3 disengages from the seat post of the public bicycle. When roller 22C8 touches After the axial groove sidewall is closed, the screw hook 22C3 then retracts in a straight line along the axial groove; conversely, when the roller 22C8 is located in the axial groove at one end of the cylindrical body of the outer support 22C1, the seventh drive motor 22C7 drives the nut 22C4 to rotate clockwise, which can first drive the screw hook 22C3 to extend axially. After the roller 22C8 touches the sidewall of the arc groove, the screw hook 22C3 then rotates 90 degrees clockwise along the arc groove, so that the hook on the screw hook 22C3 tightly hooks the seat post of the public bicycle to prevent the public bicycle from accidentally coming loose during the flipping and maneuvering process.

[0053] like Figure 9 As shown, the clamping wheel mechanism 226B includes a clamping plate 226B1, a connecting rod 226B2, a connecting seat rod 226B3, a clamping plate seat 226B4, an eighth drive motor 226B5, a push rod 226B6, and a toothed crank 226B7; the clamping plate seat 226B4 is a U-shaped strip structure with openings on its long side and both end planes, combined with...

The two sets of connecting rod transmission assemblies are symmetrically arranged, there are four connecting seat rods 226B3 and four connecting plate rods 226B2; the middle part of the clamping plate seat 226B4 is fixedly provided with an eighth driving motor 226B5, the output shaft of the eighth driving motor 226B5 is perpendicular to the extension direction of the telescopic carrier frame 226, and the output shaft of the eighth driving motor 226B5 is coaxially and fixedly connected with one of the toothed cranks 226B7; the driving of the eighth driving motor 226B5 drives the clamping plate 226B1 to move close to or away from the clamping plate seat 226B4 through the driving crank pair, the push rod 226B6, the connecting seat rod 226B3 and the connecting plate rod 226B2, i.e. the clamping plate 226B1 moves away from or close to the right inner side wall of the outer carrier frame 2261, so that the front wheel of the public bicycle is released or clamped in the right inner side wall of the outer carrier frame 2261. In this way, when the eighth driving motor 226B5 drives the two toothed cranks 226B7 to rotate synchronously and approach each other, thereby driving the two push rods 226B6 on both sides to push out at the same time, the two push rods 226B6 on both sides in turn rotate the two connecting seat rods 226B3 on both sides outward at the same time, and the two connecting seat rods 226B3 on both sides in turn push the clamping plate 226B1 outward through the connecting plate rods 226B2 hinged thereto to slide away from the clamping plate seat 226B4. In this way, when the inner carrier frame 2265 carries the public bicycle back, the clamping plate 226B1 can push the front wheel close to the right side wall of the inner carrier frame 2265 to clamp the front wheel, so as to prevent the public bicycle from accidentally loosening during the process of turning and maneuvering.Conversely, when the eighth drive motor 226B5 drives the two toothed cranks 226B7 to rotate synchronously relative to each other, thereby causing the push rods 226B6 on both sides to pull inwards simultaneously, the clamping plate 226B1 slides and retracts towards the clamping plate seat 226B4, thereby releasing the clamping state on the front wheel of the public bicycle.

[0054] The specific implementation process of this invention is as follows:

[0055] Process 1: As Figure 10 As shown, the central storage and retrieval vehicle 2 stores and retrieves public bicycles within the fixed enclosure 1, targeting support brackets in different directions. Figure 10 The orientation of step ① is the initial orientation. At this orientation, the central storage and retrieval transport vehicle 2 is lifted and lowered as a whole by two lifting drive motors 24 in sync. The central storage and retrieval transport vehicle 2 vertically transports the public bicycles from the bottom of the fixed frame 1 to the height of the support bracket for storing and retrieving the public bicycles.

[0056] The parking procedure is as follows:

[0057] Initially, the rotating vehicle frame 22 is in Figure 10 In the middle step ①, the rotating arm 227 is directly above the front end of the movable box 225, and the rotating rod 228 is directly below the rotating arm 227 and parallel to it. At this time, the telescopic frame 226 is horizontal and its length direction is perpendicular to the rotating arm 227. The public bicycle is in a flat position. The screw hook 22C3 of the seat post support hook 22C extends outward to hook the seat post of the public bicycle. The clamping plate 226B1 of the wheel clamping mechanism 226B pushes outward to clamp the front wheel of the public bicycle. The rear end face of the movable box 225 is flush with the end face of the main beam 221 near the inner wall of the fixed frame 1. The cantilever end of the rotating arm 227 points to the center of the fixed frame 1.

[0058] When the central storage and retrieval vehicle 2 is to place the public bicycles... Figure 10When the center access transport vehicle 2 wants to place the public bicycle on the support bracket in the upper left corner of the middle step ②, first, the orientation of the rotating and moving type of the vehicle frame 22 needs to be changed by the help of the reversing platform 21. In this process, the second drive motor 21 A on the reversing platform 21 needs to drive the reversing gear 217 to rotate the whole rotating and moving type of the vehicle frame 22 clockwise by 180 degrees. At this time, the reversing gear 217 simultaneously revolves counterclockwise by 45 degrees around the center of the inner half ring seat 212, and finally the overhanging end of the rotating arm 227 points to the support bracket in the upper left corner. Then, the third drive motor 224 drives the moving box 225 to slide forward along the main beam 221, and the telescopic vehicle frame 226 places the public bicycle forward to the support bracket. At this time, the screw hook 22C3 rotates to separate from the public bicycle seat tube and retracts, the clamping plate 226B1 retracts to release the clamping state of the public bicycle front wheel, and the third drive motor 224 drives the moving box 225 to return, so that the telescopic vehicle frame 226 returns with the driving moving box 225, and the public bicycle is placed on the support bracket in the upper left corner.

[0059] To place the public bicycle on the support bracket in the lower left corner of the middle step ②, the center access transport vehicle 2 needs to reach the position of the middle step ①, and then the reversing gear 217 needs to continue to rotate the whole rotating and moving type of the vehicle frame 22 clockwise by 360 degrees. At this time, the reversing gear 217 simultaneously revolves counterclockwise by 90 degrees around the center of the inner half ring seat 212, and finally the overhanging end of the rotating arm 227 points to the support bracket in the lower left corner. The subsequent storage process is the same as that in the middle step ②. Figure 10 When the center access transport vehicle 2 wants to place the public bicycle on the support bracket in the upper right corner of the middle step ③, the action of the reversing gear 217 is opposite to that of reaching the middle step ②. The subsequent storage process is the same as that in the middle step ②.

[0060] Figure 10 To place the public bicycle on the support bracket in the lower right corner of the middle step ④, the center access transport vehicle 2 needs to reach the position of the middle step ③, and then the inner half ring seat 212 needs to rotate clockwise by 90 degrees around the center of the outer half ring seat 211. At this time, the rotating and moving type of the vehicle frame 22 remains relatively stationary with the inner half ring seat 212, and finally the overhanging end of the rotating arm 227 points to the support bracket in the lower right corner. The subsequent storage process is the same as that in the middle step ②.

[0061] When the storage operation in each position is completed, the reversing gear 217 or the inner half ring seat 212 needs to reverse to drive the rotating and moving type of the vehicle frame 22 to return to the initial position of the middle step ①. Figure 10 Figure 10

[0062] When the storage operation in each position is completed, the reversing gear 217 or the inner half ring seat 212 needs to reverse to drive the rotating and moving type of the vehicle frame 22 to return to the initial position of the middle step ①. Figure 10

[0063] ​​​​The operation process of taking the car is as follows:

[0064] Initially, the rotary moving vehicle carrier 22 is empty and in the initial position of Figure 10 the middle step 1, at this time, the state of the rotary moving vehicle carrier 22 is consistent with the initial state when storing the vehicle, except that the screw hook 22C3 of the seat tube supporting hook 22C is in a retracted state, and the clamping plate 226B1 of the wheel clamping mechanism 226B is also in a retracted state;

[0065] When taking the public bicycle placed on the supporting bracket in different orientations, first change the orientation of the rotary moving vehicle carrier 22 with the help of the reversing platform 21, as when storing the vehicle, so that the overhanging end of the rotating arm 227 points to the supporting bracket where the bicycle is to be taken; then the third drive motor 224 drives the moving box 225 to slide forward along the main beam 221, and the telescopic vehicle carrier 226 is extended forward, at this time the inner vehicle carrier 2265 is sleeved around the front and rear wheels of the public bicycle, the screw hook 22C3 is extended and rotated to tighten the seat tube of the public bicycle, and the clamping plate 226B1 is pushed out to clamp the front wheel of the public bicycle, and the third drive motor 224 can then drive the moving box 225 to return, so that the telescopic vehicle carrier 226 can carry the public bicycle back to the central storage and retrieval vehicle 2 to complete the taking process.

[0066] After the taking is completed, the reversing gear 217 or the inner half ring seat 212 needs to be rotated in the opposite direction to make the rotary moving vehicle carrier 22 carry the public bicycle back to Figure 10 the initial position of the middle step 1.

[0067] Process 2: As shown in Figure 11 , the central storage and retrieval vehicle 2 performs the warehouse in and out operation on the public bicycles at the bottom layer of the fixed enclosure 1. Before performing the warehouse in and out operation, the central storage and retrieval vehicle 2 has already been in the position of Figure 10 the middle step 1, and has been lowered vertically to the bottom layer of the fixed enclosure 1.

[0068] The operation of taking the public bicycle out of the warehouse is as follows:

[0069] Initially, the state of each part of the rotary moving vehicle carrier 22 is consistent with the initial state when storing the vehicle, and the rotary moving vehicle carrier 22 carries the public bicycle in a horizontal state at the bottom layer of the fixed enclosure 1, at this time the overhanging end of the rotating arm 227 points to the door opening of the fixed enclosure 1; then the third drive motor 224 drives the moving box 225 to slide forward along the main beam 221 to the center position of the fixed enclosure 1, as shown in Figure 11 the middle step 1, the telescopic vehicle carrier 226 is extended forward; then as shown in Figure 11 the middle step 2, the fifth drive motor 22F drives the rotating arm 227 to rotate to the left side of the moving box 225, at this time the public bicycle changes from a horizontal state to a vertical state with the front wheel facing up; then as shown in Figure 11As shown in step ③, the fourth driving motor 229 drives the rotating rod 228 to rotate downward to the vertical state, at which time the public bicycle is changed from the vertical state to the horizontal state with the front wheel facing the center of the fixed enclosure 1; finally, as shown in the enlarged view of step ③ and step ④, the screw hook 22C3 is rotated to be detached from the public bicycle seat tube and is retracted, the clamping plate 226B1 is also retracted to release the clamping state of the public bicycle front wheel, the sixth driving motor 226A drives the middle carrier 2264 to translate toward the door hole, thereby driving the inner carrier 2265 to carry the public bicycle out of the door hole, at which time the person who borrows the bicycle can take the public bicycle from the inner carrier 2265, and the operation of the public bicycle out of the garage is completed. Figure 11

[0070] After the operation of the public bicycle out of the garage is completed, the inner carrier 2265 is retracted, the rotating rod 228 is rotated upward to return to the horizontal state, and then the rotating arm 227 is rotated from the left side of the moving box 225 to the front end of the moving box 225, at which time the telescopic carrier 226 returns to the horizontal state and the length direction thereof is perpendicular to the rotating arm 227, and finally the moving box 225 is moved back to return the telescopic carrier 226 to the initial position in the middle of the center access transport vehicle 2.

[0071] The operation of the public bicycle into the garage is as follows:

[0072] At the initial time, the state of each part of the rotating and moving carrier 22 is consistent with the initial state when the bicycle is taken, and the rotating and moving carrier 22 is empty and located at the bottom layer of the fixed enclosure 1, at which time the cantilever end of the rotating arm 227 also points to the door hole of the fixed enclosure 1; when the garage receives the signal of the person who borrows the bicycle requiring to enter the garage, the rotating and moving carrier 22 first performs the same action as when the bicycle is taken to send the empty inner carrier 2265 to the door hole; then, the person who borrows the bicycle pushes the public bicycle into the inner carrier 2265 and positions the pedal on the chain side of the public bicycle toward the rear wheel and on the inclined surface of the positioning lug 226C, and then the person who borrows the bicycle continues to push the public bicycle forward to make the positioning lug 226C force the pedal crank on the chain side to face the rear wheel and to be parallel to the axial plane of the front and rear wheels, thereby completing the positioning of the public bicycle on the inner carrier 2265; after that, the inner carrier 2265 is retracted, the screw hook 22C3 is extended and rotated to fasten the public bicycle seat tube, the clamping plate 226B1 is pushed out to clamp the public bicycle front wheel, the rotating rod 228 is rotated upward to return to the horizontal state, and then the rotating arm 227 is rotated from the left side of the moving box 225 to the front end of the moving box 225, at which time the telescopic carrier 226 carrying the public bicycle returns to the horizontal state and the length direction thereof is perpendicular to the rotating arm 227, and finally the moving box 225 is moved back to return the telescopic carrier 226 to the initial position in the middle of the center access transport vehicle 2, thereby completing the operation of the public bicycle into the garage.

[0073] After the operation of the public bicycle into the garage is completed, the center access transport vehicle 2 can vertically lift and carry the public bicycle to complete the operation of storing the bicycle.​

One end of the screw hook (22C3) is hook-shaped for fixing the seat tube. A protruding shaft is provided on the circumferential side of the other end of the screw hook (22C3). The protruding shaft is arranged perpendicular to the threaded shaft of the screw hook (22C3), and a roller (22C8) is coaxially mounted on the protruding shaft. The end of 22C3 with a roller (22C8) passes through the nut in sequence, driving the gear (22C5), the end face of the outer support (22C1), and the nut (22C4) and is set in the guide sleeve (22C2). The roller (22C8) is embedded in the guide groove. When the roller (22C8) is in the axial groove on the guide sleeve (22C2), it is used to guide the screw hook (22C3) to make axial linear movement. When the roller (22C8) is in the arc groove on the guide sleeve (22C2), it is used to guide the screw hook (22C3) to make 90-degree rotational movement.

8. A public bicycle garage with a circumferentially multi-layered horizontal layout according to claim 6, characterized in that, The clamping mechanism (226B) includes a clamping plate (226B1), a clamping plate seat (226B4), an eighth drive motor (226B5), and toothed cranks (226B7). The clamping plate seat (226B4) is a U-shaped elongated structure, with its opening facing the center of the outer frame (2261). The bottom surface of the clamping plate seat (226B4) is fixed to the front of one side of the outer frame (2261). Two toothed cranks (226B7) are symmetrically mounted in the middle of the clamping plate seat (226B4). Each toothed crank (226B7) is an incomplete gear, and the two toothed cranks (226B7) mesh to form a drive crank pair. Each toothed crank (226B7) is connected to the clamping plate (226B1) via a corresponding connecting rod transmission assembly. One end is hinged, and a guide hole is opened in the middle of the clamping plate seat (226B4). Multiple guide posts are installed in the middle of the clamping plate (226B1), and each guide post is slidably installed in the corresponding guide hole. An eighth drive motor (226B5) is fixedly installed in the middle of the clamping plate seat (226B4). The output shaft of the eighth drive motor (226B5) is set perpendicular to the telescopic direction of the telescopic frame (226). The output shaft of the eighth drive motor (226B5) is coaxially fixedly connected to one of the toothed cranks (226B7). The drive of the eighth drive motor (226B5) drives the clamping plate (226B1) to move closer to or away from the clamping plate seat (226B4) through the drive crank pair, push rod (226B6), connecting rod (226B3) and connecting plate rod (226B2).
