[0002] At present, in response to the increasing number of civilian and private vehicles, the shortage of parking spaces, the difficulty of parking, and the lack of parking spaces, there are usually three solutions:

[0003] Option 1: Build a large-scale multi-story parking garage. However, this option will have the following problems when it is actually implemented: 1. There are strict restrictions on parked vehicles. Vehicles with a height of more than 1.5m and a weight of more than 1.5t cannot be used, and its practical application is relatively poor; 2. It is only suitable for commercial centers and areas where public parking garages are relatively concentrated, and is not suitable for ordinary families; 3. A dedicated construction site needs to be designated, the construction period is long, the engineering technology is complex, and the construction is difficult; 4. For community users, it is not suitable for residents in residential areas far away from the parking garage; 5. It cannot be adapted to: single-family villas, townhouses, and sites with limited space.

[0004] Option 2: Adding ordinary ground parking lots and underground parking spaces. However, this option will have the following problems when it is actually implemented: 1. The space utilization rate is low, and the added parking spaces are limited and cannot meet the current parking needs; 2. Adding new parking spaces on the side of the road will reduce the usable width of the road, slow down the traffic volume, and cause traffic congestion; 3. Adding new parking spaces on the side of the road will increase traffic accidents caused by vehicle scratches, increase the blind spots of moving vehicles, and increase the risk of traffic accidents and traffic accidents.

[0005] Option three: Adding a basement parking lot. However, this option will have the following problems when it is actually implemented: 1. The basement needs to be planned simultaneously with the initial construction of the community, and there is no space for renovation in the already built community; 2. The original basement building cannot be changed once it is built. Utility Model Content

[0037] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1-16As shown, the utility model provides a 3D underground double-layer parking shed, including an intermediate frame assembly 3, a parking platform assembly 4, an end frame assembly 1, a lifting frame assembly 2, a translation drive assembly 5 and a safety protection assembly 6. The intermediate frame assembly 3 is provided with an upper and lower parking platform assembly 4, which is used to stably support and limit the upper and lower parking platform assemblies 4 through the intermediate frame assembly 3. Specifically, the intermediate frame assembly 3 includes intermediate frame columns 302 and intermediate frame beams 301. There are multiple groups of intermediate frame columns 302 and intermediate frame beams 301. Each group of intermediate frame columns 302 has four columns and corresponds to the four corners of the same rectangle. There are multiple intermediate frame beams 301 fixed across the intermediate frame columns 302 on both sides to form a rectangular frame structure through the intermediate frame columns 302 and intermediate frame beams 301 of each group. If it is arranged in this way, the intermediate frame beams 301 of the upper and lower layers of the intermediate frame assembly 3 can respectively support and limit the upper and lower parking platform assemblies 4.

[0039] See also Figures 1-15 As shown, specifically with respect to the parking platform assembly 4, the parking platform assembly 4 includes a table base plate 403, and the table base plate 403 is placed flat between the middle frame cross beams 301 at the front and rear positions, so as to stably support and limit the upper and lower table base plates 403 respectively through the middle frame cross beams 301 of the upper and lower layers, and the front and rear positions of the bottom surface of the table base plate 403 are rotatably connected to a plurality of transverse track wheels 406 through the mounting bracket 405, so as to limit and guide the translation of the table base plate 403 by linearly rolling the transverse track wheels 406 along the guide beam 304, and the front and rear positions of the table base plate 403 are respectively evenly fixed with a plurality of sets of external chains at the positions in front and behind the corresponding mounting brackets 405. The limit buckle 407 and the inner chain limit buckle 409 are used to drive the table base plate 403 at the lower position to move in translation by cooperating with the inner chain limit buckle 409 and the translation drive component 5 at the lower position, and at the same time drive the table base plate 403 at the lower position to move in translation by cooperating with the outer chain limit buckle 407 and the translation drive component 5 at the upper position. The purpose of this arrangement is that the parking platform component 4 can move in cooperation with the translation drive component 5, the end frame component 1, the intermediate frame component and the lifting frame component 2, thereby ensuring that multiple parking platform components 4 can successfully complete the vehicle's cyclic parking operation.

[0040] See also Figures 1-15As shown, both sides of the middle frame assembly 3 are combined and connected with the end frame assembly 1, and the inner periphery of the end frame assembly 1 is installed with a lifting frame assembly 2, which is used to limit and guide the vertical lifting of the lifting frame assembly 2 through the end frame assembly 1, and at the same time to lift and lower the parking platform assembly 4 at the side position through the lifting frame assembly 2. Specifically, the end frame assembly 1 includes an end frame column 101 and an end frame beam 104. There are multiple groups of end frame columns 101 and end frame beams 104. Each group of end frame columns 101 has four and respectively correspond to the four corners of the same rectangle, and multiple end frame beams 104 are fixed across the end frame columns 101 at both sides to form a rectangular frame structure through the end frame columns 101 and the end frame beams 104 at both sides. The end frame columns 101 that are close to each other are respectively fixedly connected to the middle frame columns 302 at the outermost positions on both sides. The inner positions of the end frame columns 101 on the same side that are close to each other are provided with limiting guide rails 102, which are used to limit and guide the vertical lifting of the lifting frame assembly 2 by linear cooperation between the limiting guide rails 102 and the lifting frame assembly 2. The middle and bottom parts of the end frame columns 101 are provided with motor mounting positions 103 for installing the translation drive assembly 5. The purpose of this arrangement is to limit and guide the vertical lifting of the lifting frame assembly 2 by linear cooperation between the limiting guide rails 102 on the inner side of the end frame column 101 and the limiting guide bearings 207 of the lifting frame assembly 2, and at the same time, the hydraulic motor body 503 of the translation drive assembly 5 can be stably limited and fixed through the motor mounting position 103.

[0041] See also Figures 1-15As shown, specifically to the lifting frame assembly 2, the lifting frame assembly 2 includes a lower lifting frame 202, an upper lifting beam 201 and a lifting cylinder 204. The lower lifting frame 202 and the upper lifting beam 201 are respectively provided at the upper and lower positions between the front and rear positions of the end frame assembly 1. The front and rear positions of the table substrate 403 at the edge position are respectively vertically spanned between the lower lifting frames 202 corresponding to the same side, so as to drive the table substrate 403 at the edge position to complete the lifting and lowering action by vertically lifting the lower lifting frame 202. The bottom sides of the upper lifting beam 201 are rotatably installed with lifting sprockets 205 through the sprocket mounting seat 203, and the outer periphery of the lifting sprocket 205 is engaged with a lifting chain 206. At the same time, the two ends of the lifting chain 206 are respectively engaged with the end frame beam 104 and the lower lifting frame 20 at the bottom of the end frame assembly 1 2 is fixedly connected at the top, and the end frame crossbeam 104 at the bottom of the end frame assembly 1 is vertically fixed with a lifting cylinder 204 at the position beside the lifting chain 206, and the top of the hydraulic cylinder of the lifting cylinder 204 is fixedly connected to the bottom of the corresponding upper lifting beam 201. The advantage of this arrangement is that the upper lifting beam 201 and the lower lifting frame 202 can be smoothly lifted and lowered by the extension and contraction of the lifting cylinder 204 of the lifting frame assembly 2 and the engagement of the lifting chain 206 around the lifting sprocket 205, ensuring that the parking platform assembly 4 can smoothly circulate in the entire parking shed, and because the two ends of the lifting chain 206 are respectively fixed to the end frame assembly 1 and the lower lifting frame 202, the setting of the lifting chain 206 can realize differential movement of the upper lifting beam 201 and the lower lifting frame 202 during the lifting and lowering process.

[0042] See also Figures 1-15As shown, a translation drive assembly 5 is installed between the end frame assemblies 1 at both sides, which is used to drive the upper and lower parking platform assemblies 4 to translate respectively through the translation drive assemblies 5 at the upper and lower positions. Specifically, the translation drive assembly 5 includes a hydraulic motor body 503 and a translation rotation chain 504. The motor mounting positions 103 of the end frame columns 101 at both sides are respectively fixed with the hydraulic motor bodies 503, and the hydraulic motor bodies 503 at both sides are installed diagonally staggered, and the end frame columns 101 at both sides are away from the positions of the hydraulic motor bodies 503. The driven shaft 508 is connected to the hydraulic motor body 503 at the corresponding height through the bearing seat 509, and the driven shaft 508 is respectively level with the hydraulic motor body 503 at the corresponding height. The driving shaft 502 of the hydraulic motor body 503 at the front and rear positions on the same side is coaxially fixed with a driving sprocket 506, and the front and rear positions of the driven shaft 508 are coaxially fixed with a driven sprocket 507, and the outer peripheries of the corresponding driving sprockets 506 and driven sprockets 507 on both sides are meshed and wound with a full-circle translational rotation chain 504, and the chain links of the upper and lower translational rotation chains 504 are evenly fixed with multiple chain buckles 505, and the translational rotation chain 504 at the upper position is fixed with a plurality of chain buckles 505. The chain buckle 505 of the moving chain 504 corresponds vertically to the outer chain limit buckle 407 of the parking platform assembly 4 and can be clamped with each other. At the same time, the chain buckle 505 of the translational rotating chain 504 at the lower position corresponds vertically to the inner chain limit buckle 409 of the parking platform assembly 4 and can be clamped with each other, so as to drive the table base plate 403 at the lower position to translate by cooperating and clamping the inner chain limit buckle 409 with the chain buckle 505 at the lower position, and at the same time drive the lower position to translate by cooperating and clamping the outer chain limit buckle 407 with the chain buckle 505 at the upper position. The table base plate 403 is arranged to move in translation. With such arrangement, the hydraulic motor body 503 of the translation drive assembly 5 can drive the translation rotation chain 504 to perform a circular motion, so that the chain buckle 505 of the lower translation rotation chain 504 is stuck in the inner chain limit buckle 409 of the parking platform assembly 4, which can drive the parking platform assembly 4 at the lower position to move in translation. At the same time, the chain buckle 505 of the upper translation rotation chain 504 is stuck in the outer chain limit buckle 407 of the parking platform assembly 4, which can drive the parking platform assembly 4 at the upper position to move in translation.

[0043] See also Figures 1-15As shown, the middle frame assembly 3 is installed with a safety protection assembly 6 for safety monitoring during the entire parking process. Specifically, the safety protection assembly 6 includes a signal light 601, a parking horn 602, a safety grating sensor 603, an infrared temperature sensor 604, a position switch 605 and a liquid level sensor 606. The upper position of the middle frame assembly 3 is respectively installed with a signal light 601 and a parking horn 602, the lower position of the middle frame assembly 3 is respectively installed with a safety grating sensor 603, an infrared temperature sensor 604 and a position switch 605, and the lower position of the end frame assembly 1 is respectively installed with a safety grating sensor 603, an infrared temperature sensor 604 and a liquid level sensor 606. The advantage of such an arrangement is that safety monitoring can be performed before, during and after parking during the entire parking process, ensuring that the entire parking process can operate safely and reliably.

[0044] See also Figures 1-15 As shown, the intermediate frame assembly 3 has been optimized as follows: specifically, the upper portion of the intermediate frame crossbeam 301 serves as a guide beam 304 for guiding the translational movement of the parking platform assembly 4, while the lower portion of the intermediate frame crossbeam 301 serves as a reinforcement beam 305 for enhancing the overall strength of the guide beam 304. A roller mounting bracket 307 and a chain support plate 308 are mounted on the lower intermediate frame crossbeam 301, adjacent to each other, at the inner upper and lower positions. The roller mounting bracket 307 is rotatably connected to a plurality of chain rollers 306 uniformly distributed in the transverse direction. This arrangement facilitates support and position limiting of the translational rotation chain 504 of the translation drive assembly 5 through the arrangement of the chain rollers 306 and the chain support plate 308, ensuring that the chain buckle 505 of the lower translational rotation chain 504 can smoothly engage and lock with the inner chain limit buckle 409 of the parking platform assembly 4. The edges of the front and rear intermediate crossbeams 301, which are close to each other, are integrated with anti-cut arc plates 303 to prevent damage to vehicle tires. These plates are preferably circular arc plates to prevent damage from the sharp edges of the intermediate crossbeams 301 during vehicle translation. The top surfaces of the chain supports 308 are covered with wear-resistant plates 309, which are epoxy resin plates. This arrangement ensures that the top surfaces of the chain supports 308 have good and stable wear resistance, while also ensuring that the wear-resistant plates 309 have reliable and stable wear resistance.

[0045] See also Figures 1-15As shown, the parking platform assembly 4 has been optimized as follows. Specifically, the bottom of the table base plate 403 is welded with an integrated skeleton reinforcement rib 408, so that the table base plate 403 has good and stable use strength. At the same time, the optional reinforcement rib 408 is a T-shaped steel bar, and the reinforcement rib 408 in the longitudinal position adopts a staggered design. Preferably, the reinforcement rib 408 is densely reinforced at the position corresponding to the automobile tire, so that the table base plate 403 is reliable and stable during the parking process. The top side of the table base plate 403 is covered and fixed with a raised channel 404 in the longitudinal direction. Preferably, the raised channel 404 is set on the side near the driver's seat. With this arrangement, it is more convenient to get on and off the vehicle when parking, and it is also convenient for the driver to pass smoothly after getting off the vehicle. A tilted flexible safety net 401 is mounted on the rear of the top surface of the table base plate 403 via a net bracket 402. This arrangement allows the front or rear of the vehicle to contact the flexible safety net 401 to clearly indicate that the vehicle is parked properly, ensuring that the driver can park the vehicle on the table base plate 403 smoothly.

[0046] See also Figures 1-15 As shown, the end frame assembly 1 has been optimized as follows. Specifically, the end frame column 101 is an H-shaped steel column, and the limit guide rail 102 corresponds to the inner channel of the end frame column 101, so that the limit guide rail 102 has a good and reliable use effect. There are four motor mounting positions 103 on both sides, so that the appropriate number of hydraulic motor bodies 503 can be selected and installed according to actual use needs. The inner edges of the end frame columns 101 on both sides of the same side are vertically extended and fixed with limit guide plates 107, which are used to limit and guide the vertical lifting process of the parking platform assembly 4 through the limit guide plates 107. The upper and lower parts of the end frame columns 101 close to each other on both sides and the intermediate frame columns 302 close to the outermost position are fixed together by inserting and installing bolts. At the same time, the end frame columns 101 close to each other on both sides and the intermediate frame columns 302 close to the outermost position are both uprightly extended and fixed with extended connecting plates 106 at the middle position, and the end frame columns 101 and the intermediate frame columns 302 are both strengthened and fixed by inserting and installing bolts on the extended connecting plates 106. Such an arrangement facilitates the end frame columns 101 and the intermediate frame columns 302 close to the outermost position to be stably fixed together, and at the same time, the fixed connection by the extended connecting plates 106 can prevent the bolts from interfering with the limit guide bearing 207 so that it can roll linearly along the limit guide rail 102. The end positions of the end frame cross beam 104 at the middle position and the end frame cross beam 104 at the lower position are respectively installed with an upper guide chain plate 105 and a lower guide chain plate 108 for guiding the translation drive assembly 5. With this arrangement, it is convenient to constrain and guide the circumferential rotation of the translation rotation chain 504 through the upper guide chain plate 105 and the lower guide chain plate 108 respectively.

[0047] See also Figures 1-15 As shown, the lifting frame assembly 2 has been optimized as follows. Specifically, the lower lifting frame 202 is a symmetrical, integral frame structure, ensuring reliable stability and preventing the parking platform assembly 4 from tipping over during lifting and lowering. Multiple sets of longitudinal and transverse limit guide bearings 207 are rotatably mounted at both ends of the lower lifting frame 202 and the upper lifting crossbeam 201. These guide bearings 207 linearly roll along the limit guide rails 102 to limit and guide the lifting and lowering of the parking platform assembly 4. The hydraulic lines of the lifting cylinders 204 on either side are connected in series to synchronize the operation of the lifting cylinders 204, thereby preventing the parking platform assembly 4 from tipping over during lifting and lowering due to asynchronous operation. The lifting chain 206 is at least twice the length of the lifting cylinder 204, ensuring that the lifting chain 206 has a suitable length for use.

[0048] See also Figures 1-15 As shown, the translation drive assembly 5 has been optimized as follows. Specifically, the drive shafts 502 of the hydraulic motor bodies 503 at the front and rear positions on the same side are coaxially connected by a connecting shaft 501, which is used to synchronize the rotation of the drive shafts 502 at the front and rear positions, thereby improving the stability of the operation of the translation drive assembly 5. The hydraulic motor bodies 503 are all self-locking hydraulic motors to prevent the parking platform assembly 4 from accidentally moving when moving the parking platform assembly 4 into place. The transmission ratio of the driving sprocket 506 and the driven sprocket 507 is 1. This configuration ensures that the driving sprocket 506 and the driven sprocket 507 have good transmission stability when driving the translation chain 504.

[0049] See also Figures 1-15As shown, the safety protection component 6 has been optimized as follows. Specifically, the signal light 601 and the parking horn 602 are respectively installed on the middle frame crossbeam 301 at the front position of the middle frame component 3 to provide a warning before parking, and then effectively lift outsiders before parking preparations. The safety grating sensor 603, infrared temperature sensor 604 and position switch 605 at the lower position of the middle frame component 3 are respectively installed in the middle and lower parts of the middle frame column 302 to immediately stop the translation of the parking platform component 4 when the movement of vehicles, people and pets is detected. Specifically, when the parking platform starts to operate, if a vehicle, person or pet passes by or is getting on or off the parking platform, the safety grating sensor 603, infrared temperature sensor 604 and position switch 605 will receive a signal and stop operation in time to prevent vehicles or people from being dragged or squeezed, causing damage or personal injury. The safety grating sensor 603, infrared temperature sensor 604 and liquid level sensor 606 at the lower part of the end frame assembly 1 are respectively installed in the middle and lower parts of the end frame column 101, and are used to immediately stop the lifting and lowering action of the parking platform assembly 4 when detecting the movement of people and pets getting on and off the vehicle. Specifically, because people or pets accidentally break into the end frame assembly 1 when getting on and off the vehicle, when the parking platform assembly 4 descends, there are objects, people or pets staying on the lower plane of the end frame assembly 1. At this time, the safety grating sensor 603 and the infrared temperature sensor 604 receive the signal and stop descending in time to prevent the objects, people or pets staying on the lower plane of the end frame assembly 1 from being squeezed and causing damage or personal injury. Further optionally, the liquid level sensor 606 is non-contact, and the liquid level sensor 606 is installed on the bottom surface of the end frame crossbeam 104 at the bottom position, so as to promptly issue an alarm when water accumulates at the bottom of the end frame assembly 1. Specifically, when water accumulates on the lower plane foundation of the end frame assembly 1, the liquid level sensor 606 promptly issues an alarm to remind the operator to deal with the accumulated water in time, or promptly issues an alarm to remind the owner that there is water accumulation on the lower level, thereby facilitating a timely response and removing the vehicle from the lower parking platform assembly 4 as soon as possible or raising it to the upper parking platform assembly 4 to prevent the vehicle from being soaked in water.

[0050] With the above structure, specifically in the process of setting up, since a double-layer parking platform assembly 4 is provided, the parking capacity can be doubled when the parking space is inconvenient. At the same time, it does not occupy new bottom space during setting up, and the layout can be completed after only a secondary transformation of the original parking space. Moreover, the parking platform assembly 4 has no strict height and weight restrictions on parked vehicles, and the use range of parked vehicles is wide and the applicability is good. Specifically, a double-layer circular structure parking shed is formed by the middle frame assembly 3, the lifting frame assembly 2, the end frame assembly 1, the parking platform assembly 4 and the translation drive assembly 5. The structure is simple and easy to operate, and the installation can be flexibly adjusted according to the actual situation of the installation site. The method has low requirements for the installation site. It can be installed underground or directly on the ground. The construction period is short, the comprehensive construction cost is low, the installation adaptability is strong, and the transformation space is large. Specifically, in the setting of the intermediate frame component 3, since the intermediate frame component 3 can be provided with multiple entrances and exits to enable multiple cars to enter and exit at the same time, it can also be set as a fixed entrance and exit according to the needs of the site. The setting method of the entrance and exit is flexible, which facilitates the entry and exit of vehicles, saves parking time and is conducive to improving parking efficiency. Specifically, with the translation drive component 5, since the translation drive component 5 is provided, the hydraulic motor body 503 of the translation drive component 5 can drive the translation rotation chain 504 to perform a circular motion, thereby passing through the chain buckle 505 of the lower translation rotation chain 504. The inner chain limit buckle 409 that is stuck in the parking platform assembly 4 can drive the parking platform assembly 4 at the lower position to move in translation. At the same time, the chain buckle 505 of the upper translational rotating chain 504 is stuck in the outer chain limit buckle 407 of the parking platform assembly 4, which can drive the parking platform assembly 4 at the upper position to move in translation. The translation drive method of the parking platform assembly 4 is reliable and easy to implement, which makes it convenient for the parking platform assembly 4 to drive the vehicle to move in translation. Specifically, with respect to the end frame assembly 1, since the end frame assembly 1 is provided, the vertical lifting of the lifting frame assembly 2 can be limited and guided by the linear cooperation between the limit guide rail 102 on the inner side of the end frame column 101 and the limit guide bearing 207 of the lifting frame assembly 2. At the same time, the motor mounting position 103 can stably limit and fix the hydraulic motor body 503 of the translation drive assembly 5 to prevent the hydraulic motor body 503 of the translation drive assembly 5 from moving around, and the limiting guide plate 107 at the edge of the end frame column 101 can limit and guide the vertical lifting of the parking platform assembly 4 to prevent the parking platform assembly 4 from sliding laterally off the lifting frame assembly 2 during the vertical lifting of the lifting frame assembly 2. More specifically, the intermediate frame assembly 3 is provided, so that the intermediate frame crossbeams 301 of the upper and lower layers of the intermediate frame assembly 3 can respectively support and limit the upper and lower parking platform assemblies 4, thereby ensuring that the upper and lower parking platform assemblies 4 can park vehicles at the same time.At the same time, it also ensures that the parking platform components 4 of the upper and lower layers can run smoothly. Furthermore, since the bottom of the intermediate frame component 3 is provided with a chain supporting wheel 306 and a chain supporting plate 308, the setting of the chain supporting wheel 306 and the chain supporting plate 308 can support and limit the translation rotation chain 504 of the translation drive component 5, ensuring that the chain buckle 505 of the lower translation rotation chain 504 can be smoothly matched and stuck with the inner chain limiting buckle 409 of the parking platform component 4. Specifically, as for the lifting frame component 2, since the lifting frame component 2 is provided, the upper lifting beam 201 and the lower lifting frame 202 of the lifting frame component 2 are connected by the lifting chain 206, thereby the lifting cylinder 204 of the lifting frame component 2 is extended and the lifting chain 20 6 The meshing mode of the lifting sprocket 205 can realize the smooth lifting and lowering of the upper lifting beam 201 and the lower lifting frame 202, ensuring that the parking platform assembly 4 can smoothly circulate in the entire parking shed, and since the two ends of the lifting chain 206 are respectively fixed to the end frame assembly 1 and the lower lifting frame 202, the setting of the lifting chain 206 can realize the differential movement of the upper lifting beam 201 and the lower lifting frame 202 during the lifting and lowering process. Specifically, at the two end positions of the upper lifting beam 201 and the lower lifting frame 202, since multiple sets of longitudinal and transverse limit guide bearings 207 are installed at both end positions of the upper lifting beam 201 and the lower lifting frame 202, the limit guide bearings 207 are used to move along the end The linear rolling mode of the limit guide rail 102 of the head frame assembly 1 can realize the limit guidance of the parking platform assembly 4 during the lifting and lowering process, and since the lower lifting frame 202 adopts an integral frame structure design, it ensures that the lower lifting frame 202 has a reliable stabilizing effect, preventing the parking platform assembly 4 from overturning during the lifting and lowering process. Furthermore, the hydraulic pipelines of the multiple lifting cylinders 204 of the lifting frame assembly 2 are connected in series, ensuring that the lifting cylinders 204 at both sides operate synchronously, avoiding the lifting cylinders working asynchronously and causing the parking platform assembly 4 to overturn during the lifting and lowering process. Specifically for the parking platform assembly 4, since the parking platform assembly 4 is provided, the parking platform assembly 4 and the translation drive assembly are connected. 5. The end frame assembly 1, the middle frame assembly 3 and the lifting frame assembly 2 cooperate with each other to realize the movement of the parked vehicles, ensuring that multiple parking platform assemblies 4 can successfully complete the cyclic parking operation of the vehicles. More specifically, the bottom of the table base plate 403 of the parking platform assembly 4 is welded with an integrated skeleton reinforcement rib 408, and the reinforcement rib 408 in the longitudinal position adopts a staggered design, thereby ensuring that the table base plate 403 is sturdy and durable. At the same time, the top surface of the table base plate 403 is covered and fixed with a raised channel 404. Then, the setting of the raised channel 404 makes it easier to get on and off the parked vehicle, and also facilitates the driver to pass smoothly after getting off the vehicle.
