Description

Technical Field

[0001] This invention pertains to mechanical parking devices, and more particularly to small parking equipment for lifting and moving vehicles forward and backward. Background Technology

[0002] Patent applications 202311862954.9 and 202410165908.1 describe a roadside elevated parking system with a movable and retractable vehicle platform. This system comprises a fixed frame and a forward-moving frame. The forward-moving frame is positioned between the left and right side beams of the fixed frame and can be suspended and moved forward towards the driving lane. A vehicle platform, suspended by a lifting chain, is installed in the hollow area of ​​the forward-moving frame. After the forward-moving frame moves forward above the driving lane, the vehicle platform can be lowered onto the road to pick up and drop off vehicles.

[0003] This solution is simple to construct, highly safe, and flexible in its layout, capable of generating mechanical parking spaces above the roadside. However, it still has the following significant drawbacks:

[0004] 1. To prevent the vehicle-carrying forward-mounted frame from tipping over when suspended above the road, the rear column of the fixed frame must be securely connected to the ground. This requires reliable foundation construction and the installation of pre-embedded connectors. Consequently, this results in high foundation construction and installation costs, and a lengthy construction period. Furthermore, potential quality issues with the foundation construction after installation can create safety hazards later on.

[0005] 2. Many roads have various shallowly buried municipal pipelines and sewage channels beneath the roadside. If the prior investigation is not thorough, it may cause problems during foundation construction.

[0006] 3. These small parking products often need to be dismantled or moved due to changes in environmental conditions. Since the fixing frame is firmly connected to the foundation, it will result in high construction costs when it needs to be dismantled and moved. Restoring the ground to its original state is also troublesome and takes a long time.

[0007] 4. When the current transfer frame moves in the air, there is no visible support below, which will create an unsafe visual threat to people next to it, regardless of whether it is carrying a vehicle or not, resulting in a poor user experience. Summary of the Invention

[0008] To address the aforementioned shortcomings of the prior art, the present invention proposes a forward-extending, lifting, double-layer parking device, as shown in the attached drawing, characterized by:

[0009] Its components include a fixed frame 1, a forward moving frame 2, a forward moving frame 3, and a longitudinal central sliding beam 4;

[0010] The fixed frame 1 consists of longitudinal fixed frame side beams 11 located on the upper left and right sides, and the fixed frame side beams 11 are provided with longitudinal fixed frame side beam travel rails 111 and fixed frame side beam auxiliary guide rails 112.

[0011] The forward frame 2 is composed of a front crossbeam 211 and a rear crossbeam 212, as well as a longitudinal side beam 22 located between the left and right ends of the front crossbeam 211 and the rear crossbeam 212.

[0012] The front part of the front moving frame side beam 22 is equipped with the front moving frame front wheel 221, and the rear part is equipped with the front moving frame rear wheel 224;

[0013] The forward-moving frame 3 is composed of a longitudinal forward-moving frame side beam 32 located on the upper left and right sides. The forward-moving frame side beam 32 is provided with a longitudinal forward-moving frame side beam traveling rail 321 and a longitudinal forward-moving frame side beam auxiliary guide rail 322. A forward-moving frame hanging column 31 is installed below the front end of the forward-moving frame side beam 32, and a movable column foot 5 is installed at the bottom end of the forward-moving frame hanging column 31.

[0014] The bottom height position of the movable column foot 5 can be changed and locked between the upper limit position and the lower limit position;

[0015] The middle sliding beam 4 is composed of a front guide wheel 421, a middle front guide wheel 422, a middle rear guide wheel 423, and a rear end guide wheel 424 installed on both sides of the middle sliding beam main plate 41.

[0016] The left and right forward moving frame side beam sub-guide rails 322 of the forward moving frame 3 form two sections of three-section telescopic sliding pairs on the left and right sides with the left and right middle sliding beams 4 and the left and right fixed frame side beam sub-guide rails 112 of the fixed frame 1, respectively.

[0017] When the moving column foot 5 is at the upper limit position, the forward moving frame 3 can move between the front and rear limit positions with the help of the telescopic sliding pair; when the forward moving frame 3 reaches the rear limit position, it is above the fixed frame 1, and when the forward moving frame 3 reaches the front limit position, it is above the road surface.

[0018] When the current moving frame 3 reaches the front limit position, the moving column foot 5 can be lowered to the lower limit position and locked after contacting the road surface;

[0019] After the forward transfer frame 3 reaches the front limit position, the forward transfer frame 2 can move between the fixed frame 1 and the road surface by means of the forward transfer frame front wheel 221 and the forward transfer frame rear wheel 224 along the fixed frame side beam travel rail 111 and the forward transfer frame side beam travel rail 321.

[0020] The hollow area of ​​the forward frame 2 has a vehicle platform 6, which is suspended by the forward frame platform lifting chain 23 located below the front crossbeam 211 and the rear crossbeam 212 of the forward frame.

[0021] After the current moving frame 2 moves forward to above the road surface, the vehicle carrier 6 can be lowered onto the road to pick up and drop off vehicles 7.

[0022] Compared to existing technologies, the proposed invention features a suspended forward-moving frame 3 and a forward-moving frame 2 for loading the vehicle platform, which operate independently. After the forward-moving frame 3 reaches its designated position, the movable column foot 5 below the forward-moving frame's hanging column 31 first descends to the ground, forming a rigid column supporting the forward-moving frame 3. Then, the vehicle platform 6 follows the forward-moving frame 2 and moves forward above the road surface. This creates a very stable, safe, and reliable operating process, eliminating the requirement for the fixed frame to be securely installed on the ground. As long as the hard ground surface meets general load requirements, installation can be completed simply by placing it on the ground, like a four-post table, without requiring any ground surface construction. It can be moved at any time when needed without leaving any undesirable marks on the ground. Because the pressure of the equipment's column feet on the ground is low, placing the equipment will not easily damage the municipal pipelines beneath the ground. This feature is clearly very beneficial for the promotion and implementation of the product.

[0023] Preferably,

[0024] Between the front wheel 221 and the rear wheel 224 of the front moving frame side beam 22, a front middle wheel 222 and a rear middle wheel 223 of the front moving frame are provided;

[0025] When the forward moving frame 3 moves to the front limit position, the rear end of the forward moving frame side beam traveling rail 321 is located in front of the front end of the fixed frame side beam traveling rail 111. The distance between them is less than the wheelbase between the front wheel 221 and the front middle wheel 222 of the forward moving frame, and also less than the wheelbase between the rear middle wheel 223 and the rear wheel 224 of the forward moving frame.

[0026] When the front moving frame 2 is at the rear limit position, the front middle wheel 222 and the rear wheel 224 of the front moving frame are supported by the travel rail 111 of the side beam of the fixed frame; when the front moving frame 2 is at the front limit position, the front wheel 221 and the rear middle wheel 223 of the front moving frame are supported by the travel rail 321 of the side beam of the front moving frame.

[0027] The addition of the front center wheel 222 and the rear center wheel 223 of the forward-moving frame allows the forward-moving frame 3 to move forward to a greater distance, ensuring that the vehicle platform 6 after landing can maintain a sufficient safe distance from the fixed frame 1. This allows vehicles to enter and exit the vehicle platform without having to be close to the fixed frame and other vehicles on the roadside, thus optimizing the user experience.

[0028] Preferably,

[0029] The front wheel 221 and the front center wheel 222 of the forward-moving frame are driven synchronously by a drive mechanism. Alternatively, the rear wheel 224 and the rear center wheel 223 of the forward-moving frame are driven synchronously by a drive mechanism.

[0030] Preferably,

[0031] When the forward-moving frame 2 is in the rear limit position, the forward-moving frame side beam travel rail 321 does not contact the front wheel 221 and the rear middle wheel 223 of the forward-moving frame.

[0032] Preferably,

[0033] The movable column foot 5 includes a movable column foot base 51 connected to the bottom of the forward moving frame hanging column 31.

[0034] The bottom plate 512 of the moving column base located at the bottom end of the moving column base 51 has a moving column base bottom plate hole 5121 in the middle.

[0035] The main screw 53 of the moving column foot is installed in hole 5121 of the base plate of the moving column foot;

[0036] The bottom of the main screw 53 of the moving column foot is connected to the foot plate 52 of the moving column foot.

[0037] First, screw the locking nut 531 into the main screw of the moving column foot 53, and then screw it into the bottom screw hole 542 of the moving column foot lifting block 54 inside the moving column foot base 51.

[0038] The movable column foot lifting block 54 can be changed and locked between the upper limit position and the lower limit position under the drive of the transmission mechanism.

[0039] Preferably,

[0040] When the forward moving frame 3 moves forward, the middle sliding beam 4 moves forward synchronously at half the forward moving speed of the forward moving frame 3 under the drive of the deceleration linkage mechanism;

[0041] The transmission mechanism is arranged along the front moving frame column 31 and the front moving frame side beam 32. The transmission mechanism includes a column foot horizontal drive rod end protrusion 324 located at the rear end of the column foot horizontal drive rod 323.

[0042] The column base horizontal drive rod end protrusion 324 is pushed and pulled forward within a limited distance by the elastic mechanism;

[0043] When the end protrusion 324 of the column foot horizontal drive rod is pushed and pulled to the front limit position by the elastic mechanism, the moving column foot lifting block 54 is driven to rise to the upper limit position through the transmission mechanism.

[0044] The middle sliding beam 4 is equipped with a middle sliding beam column foot lifting drive block 45. When the forward moving frame 3 is about to reach the front limit position, the column foot horizontal drive rod end protrusion 324 is pressed backward by the middle sliding beam column foot lifting drive block 45, and the middle sliding beam column foot lifting drive block 45 is driven to descend to the lower limit position and locked through the transmission mechanism, so that the moving column foot bottom plate 52 contacts the road surface.

[0045] The aforementioned preferred features simplify the transmission mechanism and improve operational ease. Other more specific beneficial effects will be further explained in the description of the embodiments.

[0046] In this article, the term "before" refers to...

[0096] Embodiment 1 of the present invention is as follows Figures 1 to 22 As shown.

[0097] See Figure 1 , Figure 2 This is an embodiment of a forward-extending, lifting, double-layer parking device with a self-propelled parking space underneath, designed according to the principles of the present invention. Its main components include a fixed frame 1, a forward-moving frame 2 arranged above the fixed frame 1, a forward-moving frame 3 installed between the fixed frame 1 and the forward-moving frame 2, and two central sliding beams 4 for slidingly connecting the fixed frame 1 and the forward-moving frame 3.

[0098] The mounting bracket 3 in this embodiment has a length of 6 meters and a depth of 2.5 meters, which is the same as the standard ground parking space marking size range, so that it can be directly applied to roadside parking spaces. The clearance height below the mounting bracket is 2.2 meters to accommodate general vehicles parking in the self-driving parking spaces below.

[0099] See Figure 3The mounting frame 1 includes two front posts 121 and two rear posts 122. Each post is equipped with adjustable feet 15 to facilitate leveling the equipment on uneven installation sites, ensuring even ground contact. The adjustable feet 15 rest on four adjustable foot pads 151 on the ground. Since the adjustable foot pads 151 have a ground contact area of ​​several hundred square centimeters, and the total weight of the equipment components and vehicle (approximately 4 to 5 tons) is distributed across the four posts, the load is only slightly over one ton. Equipment can be placed directly on standard hard surfaces that meet construction specifications without the need for reinforcement. When equipment needs to be arranged closely in rows on site, adjacent equipment posts can share the adjustable foot pads 151.

[0100] See Figure 22 Practice has proven that when a ground vehicle enters the self-driving parking space under the fixed frame 3 by reversing into the parking space, the two front columns 121 of the fixed frame 3 will provide guidance and assistance to the driver like a signpost, without increasing the difficulty of the driver's operation.

[0101] The top surface of the upper left and right side beams 11 of the fixed frame 1 is the fixed frame side beam travel rail 111, and the inner side is provided with two symmetrical V-shaped sheet metal bending parts forming the fixed frame side beam auxiliary guide rail 112.

[0102] See Figure 1 , Figure 2 Two wheel stops 8 are installed on the left and right sides near the rear of the mounting bracket 1 to guide and limit the correct parking range of the vehicle reversing into the area below the mounting bracket.

[0103] See Figure 4 , Figure 9 The left and right sides of the forward-moving frame 3 are also made of sheet metal bending as side beams 32. The top surface of the side beam 32 serves as the forward-moving frame side beam travel rail 321, and the outer surface of the side beam 32 is provided with two symmetrical V-shaped cross-sections formed by upper and lower sheet metal bending pieces as secondary guide rails 322. A forward-moving frame hanging column 31 made of rectangular steel pipe is installed below the left and right front corners of the side beam 32. A movable column foot 5 is installed at the bottom of the forward-moving frame hanging column 31. See also... Figure 1 , Figure 2 The enlarged view shows that the movable column 5 can be raised and lowered within a height range of 4 cm under the drive of the built-in drive mechanism. When the current moving frame 3 is in the returned state, the movable column 5 is in a suspended position about 4 cm off the ground.

[0104] The structure of the middle sliding beam 4 is as follows Figure 5As shown, V-grooved guide wheels 421, 422, 423, and 424 are coaxially mounted on both sides of the main body plate 41. Vertical shaft-type end pulleys 43 are installed in the openings at the lower front and rear ends of the main body plate 41. A wire rope drive chain 44 passes around the front and rear end pulleys 43, forming a taut closed loop below both sides of the main body plate 41.

[0105] See Figure 6 , Figure 7 , Figure 9 , Figure 19 The V-shaped cross-section of the forward-moving frame 3 and the secondary guide rail 322 of the forward-moving frame side beam form two three-section telescopic sliding pairs on the left and right sides with the V-shaped guide wheel of the middle sliding beam 4 and the V-shaped cross-section of the secondary guide rail 112 of the fixed frame side beam of the fixed frame 1, allowing the forward-moving frame 3 to extend forward from above the fixed frame 1 to above the road surface. When the forward-moving frame 3 moves forward, the moving column feet 5 of the forward-moving frame suspension column 31 are all suspended at a height of about 1 cm above the bottom 4, and will not rub against the flat road surface. The power for the forward and backward movement of the forward-moving frame 3 comes from the transmission mechanism installed on the fixed frame 1. See 7 and Figure 19 The transmission mechanism includes multiple forward-moving frame drive rope chain idler pulleys 171 arranged along the side beam 11 and rear crossbeam 132 of the fixed frame, and a cyclically closed, taut synchronous belt-type forward-moving frame drive rope chain 17 driven by the forward-moving frame drive motor 174. Two fixed frame middle sliding beam rope chain connecting blocks 18 on the forward-moving frame drive rope chain 17 are respectively connected to the middle sliding beam drive rope chain external connection points 441 below the rear of the left and right middle sliding beams 4. Two middle sliding beam drive rope chain external connection points 441 located on both sides of the middle sliding beam main plate 41 are respectively connected to the fixed frame middle sliding beam rope chain connecting blocks 18 and the forward-moving frame middle sliding beam rope chain connecting blocks 34. When the forward-moving frame drive motor 174 starts, the forward-moving frame drive rope chain 17 drives the middle sliding beam 4 forward, and the middle sliding beam 4 then drives the forward-moving frame 3 to move forward synchronously at twice the speed.

[0106] See Figure 8 The forward-moving frame 2 comprises a front crossbeam 211 and a rear crossbeam 212, as well as a longitudinal side beam 22 located between the left and right ends of the front and rear crossbeams 211 and 212. A front wheel 221 is mounted below the front end of the side beam 22, and a rear wheel 224 is mounted below the rear end. A front center wheel 222 is located approximately 30 cm from the front wheel 221, and a rear center wheel 223 is located approximately 30 cm from the rear wheel 224.

[0107] The two front wheels 221 and the two front middle wheels 222 of the forward moving frame can rotate synchronously under the drive of the forward moving frame translation motor 26 via the forward moving frame translation drive chain 261, the forward moving frame translation synchronous shaft 27 and the forward moving frame translation chain 24.

[0108] The forward-moving frame lifting motor 25 can drive the four forward-moving frame carrying plate lifting chains 23 with their lower ends suspended from the vehicle plates 6 to perform lifting operations via the forward-moving frame carrying plate lifting chain 23, the forward-moving frame lifting drive shaft 28, and the chain group transmission mechanism set in the forward-moving frame front crossbeam 211 and the forward-moving frame rear crossbeam 212.

[0109] See Figure 7 The power and control lines for the forward-moving frame 3 are supplied by the cable chain groove 161 and the cable chain 16 on the fixed frame 1. Similarly, the forward-moving frame 3 can also be powered in a similar manner.

[0110] See Figure 1 , Figure 9 and Figure 10 The current frame is moved to position 2 as shown. Figure 10 When the front frame is in its rearmost position, the fixed frame side beam travel rail 321 supports the rear wheel 224 and the front center wheel 222 of the front frame. Due to the pre-designed dimensions of the relevant components, when the front frame 2 is in its returned position, the rail surface of the front frame side beam travel rail 321 maintains a gap of approximately 2 mm with the front wheel 221 and the rear center wheel 223 of the front frame, preventing them from contacting each other. At this time, the front frame side beam travel rail 321 avoids bearing the pressure and frictional resistance of the front frame 2, thus allowing for easier independent forward movement.

[0111] See Figure 10 , Figure 11 and Figure 12 When the system begins vehicle storage and retrieval operations, the forward-moving frame 3, along with the central sliding beam 4, is pushed forward approximately 2.9 meters, reaching above the road surface. During the forward movement of the forward-moving frame 3, the movable column foot 5 below the forward-moving frame's hanging column 31 is in a suspended state, retracting upwards, and does not contact the road surface. Because the overall structural weight of the forward-moving frame 3 is much less than the combined weight of the stationary fixed frame 1, the forward-moving frame 2, and the vehicle-carrying platform 6, according to the lever principle, the forward-suspended forward-moving frame 3 is insufficient to cause the fixed frame 1 to tilt forward.

[0112] See Figure 13 After the forward-moving frame 3 moves into position, the movable column base 5 descends to the ground, making the forward-moving frame hanging column 31 a rigid column supporting the front end of the forward-moving frame side beam 32. Then, the forward-moving frame 2 can begin to move forward. Of course, in actual operation, to improve efficiency, the forward-moving frame 2 can begin to move slowly forward when the forward-moving frame 3 is about to reach its position. Because when the movable column base 5 lands, the forward-moving frame 2 has only moved forward by a few tens of centimeters, and the overall center of gravity of the equipment and vehicle will not shift to a dangerous position that could cause overturning.

[0113] When the forward moving frame 2 just starts to move forward, the front middle wheel 222 and the rear wheel 224 of the forward moving frame bear the weight and load of the forward moving frame 2.

[0114] See Figure 14 As the forward frame 2 continues to move forward, the front wheel 221 of the forward frame will enter above the side beam travel rail 321 of the forward frame. However, since the front middle wheel 222 of the forward frame has not left the side beam travel rail 111 of the fixed frame at this time, the wheel surface of the front wheel 221 of the forward frame is still higher than the side beam travel rail 321 of the forward frame, and there is still a gap of about 2 mm between the wheel and the rail, and the wheel body is still in a suspended state.

[0115] See Figure 15 As the forward-moving frame 2 continues to move forward, causing the front center wheel 222 of the forward-moving frame to disengage from the side beam travel rail 111 of the fixed frame, the front wheel 221 of the forward-moving frame slightly descends and contacts the rail surface of the side beam travel rail 321 of the forward-moving frame. At this time, the forward-moving frame 2 is supported by the front wheel 221 and the rear wheel 224 of the forward-moving frame.

[0116] See Figure 16 , Figure 17 , Figure 18 As the forward frame 2 continues to move forward, the rear middle wheel 223 of the forward frame enters above the rail surface of the side beam traveling rail 321 of the forward frame. Subsequently, the rear wheel 224 of the forward frame also disengages from the side beam traveling rail 111 of the fixed frame, so that the forward frame 2 is supported by the front wheel 221 and the rear middle wheel 223 of the forward frame.

[0117] See Figure 20 , Figure 21 To comply with safety regulations, paired photoelectric detection devices are installed on the front upright 121 of the fixed frame and the hanging column 31 of the forward moving frame. During the forward and backward movement of the forward moving frame 3 and the lifting and lowering of the vehicle platform 6, these photoelectric detection devices form a four-sided infrared laser beam 9 safety fence. The range of the photoelectric safety fence changes synchronously with the forward and backward movement of the forward moving frame 3. Figure 21 As can be seen, because this embodiment uses a forward-moving frame 2 with multiple sets of guide wheels, the forward-moving frame 3 can move forward significantly towards the road surface. After the vehicle platform 6 lands, there is a generous distance of approximately 0.6 meters between the vehicle 7 entering and exiting the vehicle platform 6 and the front column 121 of the fixed frame, resulting in a good user experience.

[0118] The front of the forward frame 2 and the forward frame 3 can be fitted with the forward frame decorative panel 29 and the forward frame decorative panel 36.

[0119] After the vehicle platform 6 rises to its position, the forward moving frame 2 first retracts to its original position. Then, the moving column 5 rises, and the forward moving frame 3 moves back to its original position, forming... Figure 22 The image shows the vehicle in its returned-to-position standby state. The presence of the longitudinal beam 133 in the fixed frame ensures that even if the chain breaks, the vehicle platform 6 will be immediately caught by the longitudinal beam 133, preventing a more serious overturning or crash. Therefore, the area below the fixed frame 1 constitutes a reliable safety space.

[0120] Example 2 Figures 23 to 29As shown.

[0121] This is an application scheme that can be applied to the moving column foot 5 in Example 1.

[0122] See Figure 23 The movable column foot 5 is installed in the cavity at the bottom of the forward-moving frame hanging column 31, which is made of square steel pipe.

[0123] See Figure 24 , Figure 25 The movable column base 5 consists of a movable column base body 51 enclosed by a steel plate. The movable column base base bottom plate 512 located at the bottom end of the movable column base body 51 has a movable column base base bottom plate hole 5121 in the middle.

[0124] The main screw 53 of the moving column foot is installed in the hole 5121 of the base plate of the moving column foot, and the bottom of the main screw 53 of the moving column foot is connected to the base plate 52 of the moving column foot.

[0125] First, screw the moving column foot main screw 53 into the moving column foot screw locking nut 531, and then screw it upward into the moving column foot lifting block bottom screw hole 542 of the moving column foot lifting block 54 inside the moving column foot base 51.

[0126] The upper part of the movable column foot lifting block 54 has a top shaft 541 of the movable column foot lifting block, which is guided by the vertical guide hole 514 of the movable column foot base on the side plate 511 of the movable column foot base.

[0127] The top shaft 541 of the moving column foot lifting block is hinged to the swing shaft 562 of the moving column foot three-hole plate 56 via the moving column foot double-hole support rod 55. The moving column foot three-hole plate 56 is hinged to the moving column foot base main shaft hole 516 on the moving column foot base side plate 511 via the moving column foot three-hole plate fixed shaft 561.

[0128] The moving column base three-hole plate 56's driving shaft 563 is limited by the arc-shaped limiting hole 515 of the moving column base base, so that the moving column base three-hole plate 56 only swings between two extreme angle positions.

[0129] A drive motor 58 for the moving column foot is installed above the side plate 511 of the moving column foot base.

[0130] See Figures 26 to 28 The moving column foot drive motor shaft 581 drives the moving column foot three-hole plate 56 to swing within a limited angle range via the moving column foot drive swing rod 59, the moving column foot drive connecting rod 57 and the moving column foot three-hole plate drive shaft 563, which are hinged to each other, and drive the moving column foot lifting block 54, the moving column foot main screw 53 and the moving column foot base plate 52 to move up and down.

[0131] When the movable column foot plate 52 is lowered to the lower limit position, the height of the movable column foot plate 52 is locked because the movable column foot double hole support rod 55 rotates to the dead angle position.

[0132] Based on the linkage principle, the moving column foot drive motor 58 can drive the moving column foot three-hole plate 56 to swing with a very small output torque.

[0133] Because road surfaces cannot be perfectly flat, there will inevitably be a height difference in the area where the movable column base 5 is located. Therefore, if... Figure 29 As shown, a locking nut 531 for the moving column foot screw is pre-installed on the moving column foot main screw 53.

[0134] During equipment commissioning, first loosen the locking nut 531 of the movable column foot screw, then rotate the main screw 53 of the movable column foot upwards to the highest position. After the forward moving frame 3 has moved into place, if the height of the movable column foot base plate 52 from the ground exceeds the preset limit of 4 cm, the system will drive the movable column foot 5 to descend. Then, by adjusting the locking nut 531 of the movable column foot screw and the main screw 53 of the movable column foot, the base plate 52 of the movable column foot is adjusted to the ground contact position and tightened to lock.

[0135] Example 3 Figure 30 , Figure 31 As shown.

[0136] In order to drive the moving column foot 5 to descend and land by moving the forward movement of the forward moving frame 3 which is about to be moved to the position, in order to replace the moving column foot drive motor 58, this embodiment has a column foot drive rod 311 built into the column hanging column 31, and uses the three-hole transmission plate 312 at the top of the column located at the upper end and the column foot horizontal drive rod 323 installed inside the side beam 32 of the forward moving frame.

[0137] The rear end of the column base horizontal drive rod 323 has a column base horizontal drive rod end protrusion 324.

[0138] The column base horizontal drive rod end protrusion 324 is subjected to a forward pulling force by the column base horizontal drive rod return spring 325.

[0139] See Figure 31 The column foot horizontal drive rod end protrusion 324 passes through the column foot horizontal drive rod end convex window hole 326 and reaches the rearward movement channel of the middle sliding beam column foot lifting drive block 45 fixed at the bottom of the middle sliding beam main body plate 41.

[0140] When the end protrusion 324 of the column foot horizontal drive rod is pulled to the front limit position by the elastic mechanism, the column foot lifting block 54 is driven to rise to the upper limit position through the above-mentioned linkage mechanism.

[0141] When the current moving frame 3 is about to reach the front limit position, the column foot horizontal drive rod end protrusion 324 is pressed backward by the middle sliding beam column foot lifting drive block 45, and through the above-mentioned linkage mechanism, the middle sliding beam column foot lifting drive block 45 is driven to descend to the lower limit position and locked, so that the moving column foot bottom plate 52 contacts the road surface.

[0142] Obviously, in addition to the linkage mechanism mentioned above, the connection between the column base horizontal drive rod end protrusion 324 and the moving column base three-hole plate drive shaft 563 can be achieved with a simpler handbrake cable, but the service life may be shorter.

[0143] The area beneath the mounting frame of this invention can be set up as a ground-based self-propelled parking space, as described in the above embodiments, or it can be arranged above a roadside sidewalk, above a green space, or even integrated with a building.

[0144] Charging equipment can also be installed on the rear column 122 of the fixed frame to provide charging functionality for ground-based self-propelled parking spaces.

[0145] A rain shelter can be installed above the fixed frame 1, or a rain shelter that moves with the forward-moving frame 2 can be installed on the forward-moving frame 2. The rain shelter can be combined with photovoltaic panels to provide energy storage power for the equipment itself.

[0146] Since the force required to drive the forward moving frame 3 to move forward and backward is very small after the forward moving frame 2 returns to its original position, the forward movement of the forward moving frame 3 can be achieved either by electric drive as in the above embodiment, or by a safer and more controllable manual method.
