Description

Technical Field

[0001] This application relates to the technical field of parking garages, and in particular to a multi-level bus parking garage. Background Technology

[0002] While continuously promoting green travel and vigorously developing the public transportation industry, the demand for parking lots and stations is seriously mismatched with the increase in large buses. Some buses park on the roadside to meet route requirements, which not only occupies road resources but also poses safety hazards. The emergence of mechanical multi-level parking garages for buses has effectively solved this problem.

[0003] Existing automated parking systems primarily employ two systems for vehicle entry and exit: planar movement and vertical lifting. An automated parking system consists of multiple parking levels arranged vertically, each with parking spaces. The vertical lifting system comprises elevators located next to the parking levels, which can move and stop beside each parking level. The planar movement system includes a control signal receiving device installed on the bus. This system is electrically connected to the vertical elevators to control the bus's automatic movement between parking spaces and the elevators, enabling the parking and removal of buses.

[0004] However, the aforementioned multi-level parking garages are structurally complex, resulting in a high failure rate, high construction costs per parking space, and long vehicle loading and unloading times. Summary of the Invention

[0005] In order to improve the structural complexity of existing multi-level parking garages for passenger vehicles, this application provides a multi-level parking garage for buses.

[0006] This application provides a multi-level bus parking garage, employing the following technical solution:

[0007] A multi-level parking garage for buses includes a vehicle platform and multiple vertically arranged lifting columns. Each lifting column is connected to a connecting mechanism and a driving mechanism that drives the connecting mechanism to slide vertically on the lifting column. The driving mechanism includes a driving rod connected to the connecting mechanism and a linear driving member that drives the driving rod to move in a straight line. All the connecting mechanisms are connected to the vehicle platform. A fall prevention mechanism is provided between the connecting mechanism and the vehicle platform to prevent the vehicle platform from falling after it detaches from the connecting mechanism.

[0008] By adopting the above technical solution, only a sliding connection mechanism and a fixed connection drive mechanism are needed on the lifting columns. The connection mechanisms of multiple lifting columns are all connected to a single vehicle platform, and the drive mechanism is directly set as a linear drive device. When parking a vehicle, the linear drive component drives the vehicle platform down to the ground via a drive rod. After the vehicle drives onto the platform, the drive mechanisms on multiple lifting columns work simultaneously to lift the platform along with the vehicle, allowing another vehicle to be parked to enter the parking space below the platform. When retrieving a vehicle, the vehicle parked in the lower parking space is retrieved first, and then the linear drive component lowers the platform and the vehicle above it to the ground, allowing the vehicle on the platform to be retrieved. Furthermore, the anti-fall mechanism reduces the possibility of the platform being subjected to excessive external force, causing it to detach from the connection mechanism and the upper vehicle to fall and collide with the lower vehicle. The entire automated parking system has a simple structure, low construction cost, is safe and stable, and offers convenient and quick parking and retrieval processes.

[0009] Optionally, the top surface of the lifting column facing the vehicle platform is provided with a mounting member for fixing one end of the linear drive member near the drive rod. The connecting mechanism includes a sliding frame connected to the lifting column and a first connecting member and a second connecting member connected to the sliding frame. The first connecting member is located above the second connecting member, the drive rod is fixed to the first connecting member, and the vehicle platform is fixed to the second connecting member.

[0010] By adopting the above technical solution, the entire drive mechanism is set above the vehicle platform. The linear drive component experiences greater force at the end near the drive rod. Fixing this end to the top of the lifting column makes the drive mechanism more stable. Compared to the drive mechanism pushing the vehicle platform from below, lifting the vehicle platform from above makes the force on the vehicle platform more uniform and stable. The linear drive component requires less driving force, which makes the vehicle rise and fall more stably, and further reduces the possibility of the vehicle platform detaching from the second connecting component.

[0011] Optionally, the lifting column and the surface with the mounting member are provided with vertical grooves on two surfaces adjacent to each other. The sliding frame is sleeved on the lifting column. The connecting mechanism includes a first guide wheel rotatably connected inside the sliding frame. The first guide wheel abuts against two opposite inner walls of the groove.

[0012] By adopting the above technical solution, the connecting mechanism also includes a rotating first guide wheel. The first guide wheel rolls against both sides of the inner wall of the lifting column slide groove, which makes the sliding frame more stable when sliding, thereby making the lifting of the vehicle more stable and safe.

[0013] Optionally, the connecting mechanism further includes a second guide wheel rotatably connected within the sliding frame, the second guide wheel abutting against the inner wall of the slide groove near the opposite inner wall of the other slide groove.

[0014] By adopting the above technical solution, the connecting mechanism is also provided with a second guide wheel that rolls against the inner wall of the slide groove, thereby pressing the four sides of the lifting column together. The cooperation between the first guide wheel and the second guide wheel and the slide groove not only plays a guiding and sliding role, but also increases the connection stability between the connecting mechanism and the lifting column. In addition, the rolling connection method reduces frictional resistance, thereby reducing the driving force of the linear drive component, which is more energy-efficient and reduces consumption.

[0015] Optionally, a plurality of friction strips for increasing friction are vertically attached to the inner wall of the groove, and the first guide wheel and the second guide wheel abut against the friction strips.

[0016] By adopting the above technical solution, the friction strip can increase the frictional resistance with the surfaces of the first guide wheel and the second guide wheel, thereby reducing the occurrence of guide wheel slippage and ensuring that all guide wheels can roll while the connecting mechanism slides on the lifting column, thus ensuring the stability of vehicle lifting.

[0017] Optionally, the vehicle carrier includes a frame fixedly connected to the connecting mechanism and a support frame installed within the frame for supporting the vehicle. The height of the frame on the side where the vehicle enters and exits the vehicle carrier is the same as the height of the support frame. The anti-fall mechanism includes a pusher and a stop frame. The pusher includes an extension connected to the connecting mechanism and a top joint bent and connected to the extension. The inner wall of the frame has a movable groove for the stop frame to be vertically connected. The stop frame surrounds the support frame. The vehicle carrier includes a normal state and a detached state. In the normal state, the vehicle carrier is connected to all the connecting structures, the stop frame is flush with the top surface of the support frame, and the top joint abuts against the bottom surface of the stop frame. In the detached state, the vehicle carrier is disconnected from at least one of the connecting structures, and the top joint supports the stop frame and causes the stop frame to protrude from the support frame.

[0018] By adopting the above technical solution, the anti-fall mechanism is set as a pusher and a parking stop frame that can be movably connected within the frame. The parking stop frame is a U-shaped frame surrounding the support frame. When the car platform is normally carrying a vehicle, the parking stop frame falls to the lowest position within the frame under the action of gravity. At this time, the top surface of the parking stop frame is flush with the top surface of the support frame, and the bottom surface of the parking stop frame abuts against the top surface of the pusher. After the car platform descends to the ground, the vehicle can normally drive into or out of the car platform from the short side of the frame. When a malfunction occurs in which the car platform detaches from a certain connecting mechanism, the car platform will tilt downward in the direction of detachment. At this time, the pusher fixed to the connecting mechanism will support the parking stop frame, thereby fixing the car platform and preventing the vehicle and the car platform from falling. Moreover, the pusher will lift the parking stop frame to protrude from the surface of the car platform, and the parking stop frame will stop the wheels, thereby restricting the vehicle's sliding and preventing the vehicle from sliding off the car platform, making the overall structure of the multi-level parking garage safer.

[0019] Optionally, the number of lifting columns is four and arranged in a rectangular array, and the stop frame includes four L-shaped brackets that abut against the four pushers respectively, and the four L-shaped brackets are connected in sequence to surround the support frame.

[0020] By adopting the above technical solution, the vehicle stop frame is configured to be composed of four L-shaped brackets connected in sequence. The four jacking members located on the four lifting columns can push the four L-shaped brackets respectively. When the vehicle platform is detached from a certain connecting mechanism, the corresponding jacking member can lift the corresponding L-shaped bracket. Because the detached vehicle platform will tilt towards the detachment angle, the L-shaped bracket can simultaneously restrict the wheels from moving in the direction of the tilt angle. Moreover, a single jacking member pushes a single L-shaped bracket, making the control more stable.

[0021] Optionally, a first buffer is connected between the top connection and the barrier frame, and the first buffer drives the barrier frame to move upward to the normal state.

[0022] By adopting the above technical solution, when the vehicle platform is separated from the connecting mechanism, the first buffer can absorb the pressure of the vehicle stop frame falling down with the vehicle platform, thereby slowing down the falling speed of the vehicle platform and preventing the vehicle from jumping and slipping off the vehicle platform; it can also reduce the force on the pushing component, preventing the pushing component from breaking with the connecting mechanism due to excessive stress, and further improving the structural stability of the anti-fall mechanism.

[0023] Optionally, a second buffer member is provided in the movable groove, which abuts against the side of the barrier frame opposite to the first buffer member, and the second buffer member drives the barrier frame to move downward to the normal state.

[0024] By adopting the above technical solution, the first buffer and the second buffer can work together to further improve the stability of the vehicle platform. Even if the vehicle platform is separated from the connecting mechanism, the stability of the vehicle on the vehicle platform can be guaranteed.

[0025] Optionally, the extension is slidably connected to the connecting mechanism, and the connecting mechanism is connected to a third buffer that drives the pusher to move toward the stop frame to the normal state.

[0026] By adopting the above technical solution, the jacking component and the connecting mechanism are also set to slide connection and are buffered by a third buffer component, which further absorbs the force generated when the vehicle plate separates from the connecting mechanism.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. The connecting mechanism and the fixed drive mechanism are slidably connected on the lifting column. The connecting mechanisms of multiple lifting columns are all connected to a car carrier plate. The drive mechanism is directly set as a linear drive device. The car can be stored and retrieved simply by moving the car carrier plate up and down. The structure of the entire three-dimensional parking garage is simple, the cost is low, and the process of storing and retrieving cars is convenient and fast.

[0029] 2. The anti-fall mechanism can reduce the possibility of the vehicle platform being subjected to excessive external force and detaching from the connecting mechanism, causing the vehicle above to fall and collide with the vehicle below, thus making the bus multi-level parking garage highly safe.

[0039] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0040] Example 1:

[0041] Reference Figure 1 This application discloses a multi-level parking garage for public transportation, comprising multiple parking units arranged on a foundation 7. Each parking unit includes a vehicle-carrying platform 1 and multiple vertically arranged lifting columns 2. A connecting mechanism 3 and a driving mechanism 4 are connected to the lifting columns 2, driving the connecting mechanism 3 to slide vertically along the lifting column 2. The driving mechanism 4 includes a driving rod 41 connected to the connecting mechanism 3 and a linear driving component 42 that drives the driving rod 41 to move linearly. All connecting mechanisms 3 are connected to the vehicle-carrying platform 1. A fall-prevention mechanism 5 is provided between the connecting mechanism 3 and the vehicle-carrying platform 1 to prevent the vehicle-carrying platform 1 from falling after detaching from the connecting mechanism 3. Parking and retrieval of vehicles can be achieved simply by moving the vehicle-carrying platform 1 up and down. The entire multi-level parking garage has a simple structure, low construction cost, and convenient and quick parking and retrieval processes. Furthermore, the fall-prevention mechanism 5 reduces the possibility of the vehicle-carrying platform 1 and the vehicle 8 falling, improving safety performance.

[0042] Reference Figure 2The lifting column 2 is made of steel and is fixed to the foundation 7. There are at least four lifting columns 2 arranged in a rectangular array. In this embodiment, four lifting columns 2 are preferred to enable the lifting and lowering of the vehicle platform 1. A recess 71 can be provided in the foundation 7 at the installation location of the lifting column 2. The lower end of the lifting column 2 is also pre-embedded in the foundation 7. Multiple reinforcing ribs are provided on the surrounding surface of the bottom end of the lifting column 2 to improve its stability.

[0043] Reference Figure 2 The drive mechanism 4 can be a linear drive device such as a hydraulic cylinder, pneumatic cylinder, or electric cylinder. It has a simple structure and precise control. The stroke of the linear drive member 42 driving the drive rod 41 is greater than the height of the vehicle 8. The lifting column 2 includes a column body 21. The top surface of the column body 21 facing the vehicle platform 1 is provided with a mounting member 22 for fixing one end of the linear drive member 42 near the drive rod 41. The bottom end of the drive rod 41 is fixed to the connecting mechanism 3. That is, the entire drive mechanism 4 is set above the vehicle platform 1. The end of the linear drive member 42 near the drive rod 41 is subjected to greater force. Fixing this end to the top of the lifting column 2 can make the drive mechanism 4 more stable. Compared with the drive mechanism 4 pushing the vehicle platform 1 from below, the method of lifting the vehicle platform 1 from above can make the force on the vehicle platform 1 more uniform and stable. The driving force required by the linear drive member 42 is smaller, reducing the possibility of the vehicle platform 1 detaching from the connecting mechanism 3 and the lifting column 2.

[0044] In other embodiments, the linear drive member 42 and the mounting part, the drive rod 41 and the connecting mechanism 3, the vehicle plate 1 and the connecting mechanism 3 can all be fixed by direct welding.

[0045] In this embodiment, to avoid the defect of excessive stress at the joint caused by welding, which leads to easy breakage at the joint, refer to Figure 3 Specifically, the mounting component 22 includes two first mounting plates 221 arranged opposite to each other, a first reinforcing plate 222 welded between the two first mounting plates 221, and a flange 223 connected to the first mounting plates 221. There are two flanges 223. The first mounting plates 221 and the first reinforcing plate 222 are both welded to the column 21. An installation space is formed between the two first mounting plates 221 for the end of the linear drive component 42 to fit into. Opposite connecting columns are provided on the side of the end of the linear drive component 42. The middle part of the flange 223 is interference-fitted onto the connecting column and fixed to the first mounting plate 221 by bolts, thereby fixing the drive mechanism 4 to the lifting column 2.

[0046] Reference Figure 3The connecting mechanism 3 includes a sliding frame 31 connected to the lifting column 2 and a first connecting member 32 and a second connecting member 33 connected to the sliding frame 31. The first connecting member 32 is located above the second connecting member 33. The drive rod 41 is fixed to the first connecting member 32 and the vehicle plate 1 is fixed to the second connecting member 33.

[0047] A connector 43 is sleeved on the end of the drive rod 41 away from the linear drive member 42. The connector 43 has a through hole. The first connecting member 32 includes a second mounting plate 321, a second reinforcing plate 322, a pin 323, and a limiting plate 324. The second mounting plate 321 is welded to the sliding frame 31. The second reinforcing plate 322 is welded between the two second mounting plates 321 and also welded to the sliding frame 31. An installation space is formed between the two second mounting plates 321 for the connector 43 to enter. The side of the pin 323 has a slot near both ends. After the pin 323 passes through the through hole of the two second mounting plates 321 and the connector 43, the mounting plate is engaged in the slot and fixed to the mounting plate by bolts, thereby fixing the drive rod 41 to the connecting mechanism 3.

[0048] The structure of the second connector 33 is the same as that of the first connector 32 and is symmetrically arranged along the horizontal center plane of the sliding member. The two side walls along the longitudinal direction of the vehicle plate 1 are fixed with spherical bearings 13. The spherical bearings 13 can realize universal rotation at the connection point and have the characteristics of large load capacity and strong impact resistance. The spherical bearings 13 enter between the two second mounting plates 321 of the second connector 33. The vehicle plate 1 and the connecting mechanism 3 are fixedly installed by passing through the pin 323 and the fixed limiting plate 324.

[0049] Reference Figure 3 The column 21 has vertically spaced grooves 211 on two surfaces adjacent to the surface with the mounting component 22, meaning the column 21 can be directly made of I-beams. A sliding frame 31 is fitted onto the lifting column 2. The sliding frame 31 includes an I-shaped plate 311 and a back plate 312 sealing the I-shaped opening of the I-shaped plate 311. The I-shaped plate 311 and the back plate 312 are bolted together, forming a through groove for the lifting column 2 to pass through. (Refer to...) Figure 4 and Figure 5To make the sliding frame 31 more stable when sliding, the connecting mechanism 3 also includes a first guide wheel 34 rotatably connected to the C-shaped plate 311. The first guide wheel 34 abuts against two opposite inner walls of the slide groove 211. Two first guide wheels 34 can be arranged vertically at intervals on one side of the C-shaped plate 311, so there are a total of four guide wheels in one connecting mechanism 3. When the connecting mechanism 3 slides down and up on the lifting column 2, the first guide wheels 34 rotate in opposite directions. Furthermore, the connecting mechanism 3 also includes a second guide wheel 35 rotatably connected to the sliding frame 31. The number of second guide wheels 35 on one side of the C-shaped plate 311 can also be set to two and arranged vertically at intervals between the two first guide wheels 34. The second guide wheel 35 abuts against the inner wall of the slide groove 211 near the opposite slide groove 211. Thus, the cooperation of the eight guide wheels and the slide groove 211 can press the four sides of the lifting column 2 together. While playing a guiding and sliding role, it can also increase the connection stability between the connecting mechanism 3 and the lifting column 2. In addition, the rolling connection method reduces frictional resistance, thereby reducing the driving force of the linear drive component 42, which is more energy-efficient and reduces consumption.

[0050] Reference Figure 4 Multiple friction strips 23 are vertically affixed to the inner wall of the slide groove 211 to increase friction. The friction strips 23 can be made of materials with a high coefficient of friction, such as nylon strips or frosted strips. The first guide wheel 34 and the second guide wheel 35 both abut against the friction strips 23. The friction strips 23 can increase the frictional resistance with the surfaces of the first guide wheel 34 and the second guide wheel 35, thereby reducing the occurrence of guide wheel slippage. This ensures that while the connecting mechanism 3 slides on the lifting column 2, all guide wheels can roll, thus ensuring the stability of the vehicle 8 during lifting.

[0051] Reference Figure 2 The vehicle platform 1 is also made of steel structure material. The vehicle platform 1 includes a frame 11 fixedly connected to the connecting mechanism 3 and a support frame 12 installed in the frame 11 to support the vehicle 8. The width of the frame 11 is greater than the width of the vehicle 8. The height of the frame 11 is the same as the height of the vehicle platform 1 on the side where the vehicle 8 enters and exits, so that the vehicle 8 can enter and exit. Furthermore, the side of the frame 11 where the vehicle 8 enters and exits can be provided with a transition surface 111 that slopes downward away from the support frame 12. It should be noted that the vehicle 8 can enter and exit the vehicle platform 1 in one direction, that is, the frame 11 is provided with two transition surfaces 111. Preferably, in order to improve the space utilization of the foundation 7, the vehicle 8 preferably enters and exits from one side of the vehicle platform 1. In this case, the frame 11 only needs to be provided with one transition surface 111. The support frame 12 is composed of several parallel steel bars spliced ​​together. There are gaps between adjacent steel bars to allow dust, rainwater and other impurities to pass through, which facilitates the cleaning of the multi-level parking garage. Horizontal bars are also vertically connected among the steel bars for reinforcement. In addition, a receiving groove 72 with the same height as the thickness of the vehicle platform 1 can be opened on the foundation 7 to facilitate the entry and exit of vehicles 8.

[0052] In other embodiments, the fall arrest mechanism 5 can be directly configured as a fall arrest hook fixed to the side of the U-shaped plate 311 facing the vehicle platform 1. The vehicle platform 1 is provided with a protrusion. When the vehicle platform 1 is separated from the second connecting member 33, the fall arrest hook can catch the protrusion, thereby playing a role in buffering the fall. An alarm can be provided on the protrusion. When the fall arrest hook touches the alarm on the protrusion, it can remind the staff to repair it in time to avoid the vehicle platform 1 from completely separating from the connecting mechanism 3.

[0053] In this embodiment, refer to Figure 2 The anti-fall mechanism 5 includes a pusher 51 and a stop frame 52. The pusher 51 includes an extension 511 connected to the connecting mechanism 3 and a top connection 512 bent and connected to the extension 511. An annular movable groove 112 is provided along the inner wall of the frame 11. The stop frame 52 is a U-shaped frame surrounding the support frame 12. The outer wall of the stop frame 52 is provided with a sliding part 522 that slides within the movable groove 112. The sliding part 522 can be configured as a protrusion with a thickness smaller than the width of the movable groove 112. The vehicle platform 1 has a normal state and a detached state. In the normal state, the vehicle platform 1 is connected to all connecting structures. The stop frame 52 slides down to the bottom of the movable groove 112 under the action of gravity. The top surface of the stop frame 52 is flush with the top surface of the support frame 12. The top joint 512 abuts against the bottom surface of the barrier frame 52, allowing the vehicle 8 to drive normally into or out of the vehicle platform 1 after it descends to the ground. In the detached state, the vehicle platform 1 disengages from the second connecting member 33 of at least one connecting mechanism 3, causing the vehicle platform 1 to tilt downwards in the detachment direction. At this time, the push member 51 fixed to the connecting mechanism 3 supports the barrier frame 52, thereby fixing the vehicle platform 1 and preventing the vehicle 8 and the vehicle platform 1 from falling. Moreover, the top joint 512 pushes the barrier frame 52 up to protrude from the surface of the vehicle platform 1, and the barrier frame 52 blocks the wheels, thereby restricting the sliding of the vehicle 8 and preventing the vehicle 8 from sliding off the vehicle platform 1, making the overall structure of the multi-level parking garage safer.

[0054] In this embodiment, refer to Figure 6 The extension 511 is horizontally fixedly connected to the sliding frame 31, and the top connection 512 is vertically connected to the extension 511. The top connection 512 passes under the frame 11 and abuts against the bottom surface of the barrier frame 52. Furthermore, a first buffer 53 is connected between the top connection 512 and the barrier frame 52. The first buffer 53 drives the barrier frame 52 to move upward to the normal state. When the vehicle platform 1 is disengaged from the connecting mechanism 3, the first buffer 53 can absorb the pressure of the barrier frame 52 falling downward with the vehicle platform 1, thereby slowing down the falling speed of the vehicle platform 1 and preventing the vehicle 8 on the vehicle platform 1 from bouncing and slipping; it can also reduce the force on the pushing member 51 and prevent the pushing member 51 from breaking with the connecting mechanism 3 due to excessive stress.

[0055] Furthermore, refer to Figure 6 The top wall of the movable groove 112 is provided with a second buffer 54 that abuts against the sliding part 522 on the barrier frame 52, facing away from the first buffer 53. Multiple second buffers 54 are arranged in a circular array along the barrier frame 52. The second buffers 54 drive the barrier frame 52 to move downward to the normal state. The first buffer 53 and the second buffer 54 can be made of the same components, both of which are springs or rubber pads, preferably steel springs so as to withstand greater forces. The cooperation of the first buffer 53 and the second buffer 54 can further absorb the shaking of the vehicle platform 1 during movement, which can not only reduce the occurrence of the vehicle platform 1 disengaging from the connecting mechanism 3, but also ensure the stability of the vehicle 8 on the vehicle platform 1 even if the vehicle platform 1 disengages from the connecting mechanism 3.

[0056] In one embodiment, the vehicle stop frame 52 can be a fixed U-shaped frame. In a preferred embodiment, the vehicle stop frame 52 includes four L-shaped brackets 521 that abut against four pushers 51, the four L-shaped brackets 521 being connected sequentially to form a U-shaped frame. The four pushers 51 located on the four lifting columns 2 can push the four L-shaped brackets 521 respectively. When the vehicle platform 1 detaches from a certain second connecting member 33, the corresponding pusher 51 can lift the corresponding L-shaped bracket 521. Because the detached vehicle platform 1 will tilt towards the detachment angle, the L-shaped bracket 521 can simultaneously restrict the wheels from moving in the direction of the tilt angle, and the single pusher 51 pushes a single L-shaped bracket 521, resulting in more stable control.

[0057] Reference Figure 2 The parking unit also includes a rain shelter mechanism 6, which includes a rain shelter 61. A support column 62 is vertically fixed to the top of the lifting column 2. The rain shelter 61 is fixed to the end of the support column 62 away from the lifting column 2. The rain shelter 61 has an arc-shaped structure to prevent water accumulation. A crossbeam 63 connects two adjacent support columns 62 along the length of the vehicle platform 1. Two crossbeams 63 are spaced vertically apart, and a tie rod 64 is inclinedly connected between the two crossbeams 63 to enhance structural stability. Additionally, to reduce the possibility of water accumulation inside the parking unit, refer to... Figure 7 The side wall of the settling tank 71 near the receiving tank 72 is provided with a guide channel 73 that slopes towards the bottom of the settling tank 71. A drainage ditch 74 connected to the settling tank 71 is also provided in the foundation 7. The drainage ditch 74 can discharge any water that may accumulate in the settling tank 71 to the outside of the bus parking garage. Moreover, when the vehicle platform 1 descends into the receiving tank 72, the guide channel 73 makes way for the pusher 51 located horizontally below the vehicle platform 1, so that the pusher 51 is not interfered with by the surface of the foundation 7.

[0058] The implementation principle of Embodiment 1 of this application is as follows:

[0059] Simply slide the connecting mechanism 3 and fix the drive mechanism 4 on the lifting column 2. The connecting mechanisms 3 of multiple lifting columns 2 are all connected to a vehicle platform 1. The drive mechanism 4 is directly set as a linear drive device. When parking a vehicle, the linear drive component 42 moves downward through the drive rod 41 to drive the vehicle platform 1 to the ground through the connecting mechanism 3. After the vehicle 8 drives onto the vehicle platform 1, the drive mechanisms 4 on multiple lifting columns 2 work synchronously to lift the vehicle platform 1 together with the vehicle 8. Another vehicle 8 waiting to be parked can drive into the parking space below the vehicle platform 1. When retrieving a vehicle, first take out the vehicle 8 parked in the parking space below, and then lower the vehicle platform 1 and the vehicle 8 above it to the ground through the action of the linear drive component 42, and take out the vehicle 8 on the vehicle platform 1.

[0060] In addition, when an unexpected situation occurs in which the vehicle platform 1 detaches from the second connecting member 33 of the connecting mechanism 3, the vehicle platform 1 will tilt downward in the direction of detachment. At this time, the push member 51 fixed to the connecting mechanism 3 will support the barrier frame 52, thereby fixing the vehicle platform 1 and preventing the vehicle 8 and the vehicle platform 1 from falling. Moreover, the top joint 512 will push the barrier frame 52 to protrude from the surface of the vehicle platform 1, and the barrier frame 52 will block the wheels, thereby restricting the sliding of the vehicle 8 and preventing the vehicle 8 from sliding off the vehicle platform 1, thus improving the overall safety of the bus parking garage structure.

[0061] Example 2:

[0062] Reference Figure 8 This application discloses a multi-level bus parking garage, which is an optimization based on Embodiment 1. To further improve safety, the pushing member 51 and the connecting mechanism 3 are configured as a sliding connection. Specifically, the connecting mechanism 3 also includes a guide post 313 vertically arranged and connected to the lower edge of the U-shaped plate 311. The end of the extension 511 away from the top connection 512 is sleeved on the guide post 313 and can slide on the guide post 313. The bottom end of the guide post 313 is also sleeved with a third buffer member 55. The top end of the third buffer member 55 abuts against the extension 511. The third buffer member 55 drives the pushing member 51 to move towards the barrier frame 52 to the normal state. The third buffer member 55 is also preferably configured as a steel spring, which not only reduces the occurrence of the vehicle platform 1 separating from the second connecting member 33, but also further absorbs the force generated when the vehicle platform 1 separates from the second connecting member 33, preventing the vehicle platform 1 from completely separating from the connecting mechanism 3.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
