Description

Technical Field

[0001] This invention belongs to the field of parking equipment technology, and particularly relates to a comb-tooth exchange parking system and a comb-tooth exchange parking method. Background Technology

[0002] Comb-type parking is widely used as an unmanned intelligent parking solution, but its parking and retrieval area often requires a pit to facilitate lifting and switching.

[0003] However, the excavation pit is not level with the ground, so a dedicated pit entrance and exit are required. Even so, the movement of the transport vehicle is not as smooth as on flat ground. Furthermore, the construction of the pit must meet many standards, such as installing protective railings around it to improve safety and a drainage system within the pit to remove stagnant water and ensure its normal operation. Therefore, the presence of the pit adds many construction steps, and each step must meet its own construction standards. If any step fails to meet a standard, it will lead to unsafe use of the pit, damaging the transport vehicle and causing inconvenience for the comb-tooth exchange and parking. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the aforementioned problems in the prior art, this invention provides a comb-tooth exchange parking system and a comb-tooth exchange parking method, thereby solving the technical problem that the increased difficulty of transporting vehicles due to the pit excavation.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] On one hand, the present invention provides a comb-tooth interchangeable parking system, including a parking bay, a support frame, two lateral sliding base frames, and two comb-tooth frames. The support frame is supported on the bottom surface of the parking bay, and the two together form a driving space. The two lateral sliding base frames are symmetrically arranged on the left and right sides of the support frame, and can move synchronously between extended positions close to each other and retracted positions far apart from each other, and can travel on the bottom surface. The lateral sliding base frames are comb-tooth structures with first comb teeth. The two comb-tooth frames are symmetrically arranged on the left and right sides of the support frame and can move synchronously between low and high positions above the bottom surface. The comb-tooth frames are comb-tooth structures with second comb teeth. When the two lateral sliding base frames travel to the extended position on the bottom surface and the two comb-tooth frames are in the low position, the second comb teeth and the first comb teeth intersect to form a driving platform for supporting the vehicle tires. The two lateral sliding base frames are fixed in the height direction or can move synchronously with the two comb-tooth frames.

[0009] Furthermore, the bottom surface is flush with the ground outside the parking area.

[0010] Furthermore, it also includes four vertical guide rails arranged in a rectangular shape on the support, with lifting mechanisms installed on the vertical guide rails. Each end of the comb frame is connected to two vertical guide rails on the same side through a lifting mechanism, and the lifting mechanism enables the comb frame to move up and down along the vertical guide rails.

[0011] Furthermore, the comb frame is equipped with a centering push rod. The centering push rods on the two comb frames are symmetrical. The centering push rods are connected to the comb frame through a centering push-pull mechanism so that the centering push rods are pushed out or retracted synchronously.

[0012] Furthermore, the comb frame is provided with multiple sets of first rollers arranged in the front-back direction, each set of first rollers including multiple first rollers arranged in the left-right direction, and the axis of the first rollers is in the front-back direction; the first comb teeth are provided with multiple sets of second rollers arranged in the front-back direction, each set of second rollers including multiple second rollers arranged in the left-right direction, and the axis of the second rollers is in the front-back direction, and at least the upper surface of the first rollers constitutes the travel platform.

[0013] Furthermore, the transverse base is provided with multiple second rollers, the axis of which is in the front-to-back direction, and the second rollers travel on the bottom surface; or the first comb tooth is inlaid with multiple sets of second rollers arranged in the front-to-back direction, each set of second rollers including multiple second rollers arranged in the left-to-right direction, the axis of which is in the front-to-back direction. When the transverse base and the comb tooth frame located at the lower position together form a traveling platform for supporting the vehicle tires, the upper surface of the first roller and the upper surface of the second roller together constitute the traveling platform, and / or the second roller travels on the bottom surface.

[0014] Furthermore, it also includes a transport vehicle, which includes a comb plate that can be raised and lowered between a low limit and a high limit. The comb plate is provided with a third comb tooth that can intersect with the second comb tooth. When the transport vehicle travels to the space below the comb plate while the comb frame is in a high position and the comb plate is in a low limit position, the comb plate moves to the high limit position, which is higher than the comb frame, through the intersecting of the third comb tooth and the second comb tooth.

[0015] Furthermore, the width of the transport vehicle is greater than the distance between the two transverse base frames when they are in the extended position.

[0016] Furthermore, an uphill ramp is provided at one end of the car hall, with the apex of the ramp being equal to the height of the transverse underframe to facilitate vehicle entry and exit; the end of the car hall with the uphill ramp serves as the vehicle entrance and exit, while the end of the car hall furthest from the vehicle entrance and exit serves as the entrance and exit for the transport vehicle.

[0017] On the other hand, the present invention also provides a comb-tooth exchange parking method, comprising the following steps:

[0018] S1: The transverse base extends to the extended position, the comb frame is in the low position, and the two form two travel platforms on the left and right sides;

[0019] S2: The vehicle enters the parking lot, at which point the wheels on both sides of the vehicle are supported on the left and right driving platforms respectively, and the vehicle is parked in place;

[0020] S3: The comb frame moves up to a high position, the vehicle is lifted, and the height of the two transverse base frames remains unchanged or moves up with the comb frame;

[0021] S4: The two transverse base frames move to the retracted position to make room for the transport vehicle;

[0022] S5: The transport vehicle on the ground moves to the bottom surface between the two transverse base frames and stops directly under the vehicle. At this time, the comb plate is in the low limit position.

[0023] S6: The comb plate moves to its highest limit, and the vehicle is supported by the comb plate;

[0024] S7: The transport vehicle carries the vehicle out of the parking lot.

[0025] (III) Beneficial Effects

[0026] The beneficial effects of this invention are:

[0027] This invention provides a comb-tooth exchange parking system and method, comprising a pitless parking hall and a pair of transverse sliding frames and comb-tooth frames installed within the hall. The first comb teeth of the transverse sliding frame on the same side and the second comb teeth of the comb-tooth frame interlock to form a flat platform supporting the vehicle tires, making vehicle entry smoother. Furthermore, the comb-tooth frames can rise, elevating the vehicle to create space for a transport vehicle underneath, facilitating vehicle transfer. The transverse sliding frame can retract, providing space for the transport vehicle. This space functions similarly to a pit in existing technology. Simultaneously, the ground inside and outside the parking hall is at the same level, allowing the transport vehicle to move smoothly between the parking hall and the transport vehicle, enabling vehicle exchange between the transport vehicle and the parking hall without a pit. Therefore, the comb-tooth exchange parking system and method of this invention solve the technical problem of increased difficulty in transport vehicle movement due to pits, and have wider applicability.

[0047] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0048] Example 1

[0049] like Figure 1-11As shown, this embodiment provides a comb-tooth exchange parking system, such as... Figure 5 , Figure 6 As shown, the parking system in this embodiment includes a parking hall, a support frame 1, two transverse sliding base frames 2, two comb frames 3, and a transport vehicle 6.

[0050] like Figure 2 , Figure 11 As shown, the floor 4 inside the vehicle compartment is flush with the ground 5 outside the vehicle compartment, facilitating the smooth entry and exit of the transport vehicle 6. The support frame 1 rests on the floor 4, and the vehicle compartment and the support frame 1 form a driving space. The support frame 1 includes four supports arranged in a rectangle, fixed to the floor 4. When the floor 4 is a cement surface, the supports are fixed to the floor 4 using expansion bolts; when the floor 4 is a steel platform, the supports are fixed to the floor 4 by welding. Two supports on the same side are connected by connectors, and the two connectors are connected by an inverted U-shaped frame, making the four supports form a whole. The structure of the support frame 1 helps to strengthen its strength and control its deformation. Of course, the invention is not limited to this. In other embodiments, the supports can be arranged in pairs (more than two sets), or a frame can be directly connected to the top of the paired supports, or the connectors can be replaced with one or more connecting rods.

[0051] like Figure 3-6 , Figure 11 As shown, two transverse sliding base frames 2 are symmetrically arranged on the left and right sides of the support 1, and can move synchronously between their extended positions (close to each other) and retracted positions (far apart from each other), and can travel on the bottom surface 4. Figure 4-6 , Figure 11 As shown, two comb frames 3 are symmetrically arranged on the left and right sides of the support 1 and can synchronously rise and fall between a low position and a high position above the bottom surface 4. The transverse base frame 2 is a comb structure with a first comb tooth, and the comb frame 3 is a comb structure with a second comb tooth. The comb structure of both is constructed as follows: Figure 10 As shown, when the lateral sliding base 2 and the comb tooth frame 3 are on the same horizontal plane, the first and second comb teeth complement each other by interlacing one first comb tooth and one second comb tooth, filling the gaps between the comb teeth. The second comb tooth and the first comb tooth overlap in an alternating manner to form a relatively flat platform for supporting the vehicle tires. When the two lateral sliding base frames 2 move to the extended position on the bottom surface 4 and the two comb tooth frames 3 are in the low position, the second comb tooth and the first comb tooth overlap in an alternating manner to form a platform for supporting the vehicle tires. Of course, the specific structure of "the second comb tooth and the first comb tooth overlap in an alternating manner" in this invention is not limited to the above-mentioned "complementary manner of interlacing one first comb tooth and one second comb tooth". In addition, the comb tooth frame 3 is also used to lift the vehicle, so it can also be overlapped in an alternating manner by multiple first comb teeth, one second comb tooth, or multiple first comb teeth.

[0052] In this embodiment, the two transverse base frames 2 are fixed in the height direction, meaning that the transverse base frames 2 are connected to the bottom of the support and can move laterally. When the two transverse base frames 2 are in the extended position and the two comb frames 3 are in the low position, a traveling platform is formed.

[0053] Specifically, such as Figure 2-6 , Figure 9-11 As shown, the transverse base frame 2 is connected to the bottom of the support via a push-pull device, and is supported on the bottom surface 4, thus allowing it to move laterally on the bottom surface 4. The push-pull device can be a hydraulic cylinder, pneumatic cylinder, lead screw, or rack and pinion, etc. Meanwhile, as... Figure 3-6 , Figure 9 As shown, the first comb tooth is provided with multiple sets of second rollers 21 arranged in the front-to-back direction, facilitating the movement of the transverse base frame 2 on the bottom surface 4. Each set of second rollers 21 includes multiple second rollers 21 arranged in the left-to-right direction, with the axis of the second rollers 21 in the front-to-back direction. When the end face of the protruding end of the first comb tooth is provided with a sealing plate to connect the first comb tooth into a whole, the second rollers 21 can be located below the sealing plate or embedded in the first comb tooth. When the end face of the retracted end of the first comb tooth is provided with a crossbeam to connect the first comb tooth into a whole, the second rollers 21 can be located below the first comb tooth or embedded in the first comb tooth.

[0054] In summary, when the transverse base frame 2 and the comb frame 3 located at the lower position together form a platform for supporting the vehicle tires, the second roller 21 travels on the bottom surface 4.

[0055] In addition, such as Figure 10 As shown, the front end of the transverse chassis 2 is equipped with a protruding wheel stop to prevent the vehicle wheels from entering the parking position. Behind the wheel stop is a wheel groove, which provides a feeling of the wheels being sucked in when the vehicle is parked, thus enhancing the feel of parking.

[0056] In this embodiment, as Figure 1-2 , Figure 7 , Figure 9 As shown, the bracket 1 is equipped with four vertical guide rails 8 arranged in a rectangle. Each vertical guide rail 8 has a lifting mechanism 81. The front and rear ends of each comb tooth frame 3 are connected to two vertical guide rails 8 on the same side via a lifting mechanism 81. The lifting mechanism 81 allows the comb tooth frame 3 to move up and down along the vertical guide rails 8. Figure 8 As shown, the comb frame 3 is also equipped with guide frames and guide wheels. A guide frame perpendicular to the second comb tooth is provided at both the front and rear ends. The guide wheels are located on both sides of the guide frames and are engaged with the inner side of the vertical guide rail 8, allowing the comb frame 3 to move only up and down along the vertical guide rail 8. The lifting mechanism 81 can be a hydraulic cylinder, pneumatic cylinder, lead screw, or gear rack, etc.

[0057] like Figure 4 , Figure 7-8 , Figure 10-11 As shown, a centering push rod 31 is provided on the comb frame 3. The centering push rods 31 on the two comb frames 3 are symmetrical. The centering push rods 31 are connected to the comb frame 3 through the centering push-pull mechanism 32 so that the centering push rods 31 are pushed out or retracted synchronously.

[0058] At the same time, such as Figure 7-8 , Figure 10 As shown, the comb frame 3 is equipped with multiple sets of first rollers 33 arranged in the front-to-back direction. Each set of first rollers 33 includes multiple first rollers 33 arranged in the left-to-right direction. The axes of the first rollers 33 are embedded in the second comb teeth in the front-to-back direction. When the comb frame 3 carries a vehicle, the first rollers 33 can roll in contact with the vehicle tires. The two centering push rods 31 are pushed out simultaneously, and with the help of the rolling contact between the first rollers 33 and the vehicle tires, the vehicle on the comb frame 3 is moved laterally to the center, correcting the user's parking tilt. The centering push-pull mechanism 32 can be a hydraulic cylinder, a pneumatic cylinder, a lead screw, or a gear rack, etc. The centering push rods 31 are parallel to the second comb teeth, positioned above the second comb teeth, and have a gap between them and the first rollers 33. When the centering push rods 31 move, they will not rub against the first rollers 33. The aforementioned overhead platform includes the upper surface of the first roller 33. Of course, this upper surface is not a fixed surface of the first roller 33. As the first roller 33 rotates, the upper surface of the first roller 33 is always its upper surface.

[0059] like Figure 5-6 As shown, the transport vehicle 6 includes a comb plate 61 that can be raised and lowered between a low limit and a high limit. The comb plate 61 is provided with a third comb tooth that can intersect with the second comb tooth. When the transport vehicle 6 travels to the space below the comb plate 61 with the comb frame 3 in a high position and the comb plate 61 in a low limit position, the comb plate 61 moves to the high limit position through the intersecting of the third comb tooth and the second comb tooth, which is higher than the comb frame 3, thereby forming an intersecting exchange platform with the comb frame 3 for exchanging and transferring vehicles with the car hall.

[0060] In particular, the width of the transport vehicle 6 is greater than the distance between the two transverse base frames 2 when they are in the extended position, which makes the transport vehicle 6 more stable. Therefore, before the transport vehicle 6 enters the hall, the two transverse base frames 2 move to the retracted position to make room for the transport vehicle 6.

[0061] To make the vehicle enter the parking lot more smoothly, such as Figure 2 As shown, an uphill ramp 7 is provided at the vehicle entrance / exit of the car hall. The apex of the uphill ramp 7 is at the same height as the transverse sliding frame 2 so that vehicles can smoothly drive onto the overhead platform. Correspondingly, the end of the car hall away from the vehicle entrance / exit is the entrance / exit of the transport vehicle 6.

[0062] It should be noted that in this invention, "front" refers to the direction in which the vehicle enters the vehicle hall, while "rear" refers to the direction opposite to "front".

[0063] The present invention also provides a comb-tooth exchange parking method, comprising the following steps:

[0064] S1: The transverse base frame 2 extends to the extended position, and the comb frame 3 is in the low position, forming two travel platforms on the left and right sides;

[0065] S2: The vehicle enters the hall. The vehicle enters the hall from the vehicle entrance through the uphill ramp 7. At this time, the two wheels of the vehicle are supported on the left and right driving platforms respectively. The vehicle stops when the front wheels are blocked by the wheel chocks and enter the wheel drop groove.

[0066] S3: The comb frame 3 moves up to a high position, the vehicle is lifted, and the height of the two transverse base frames 2 remains unchanged;

[0067] S4: The two transverse base frames 2 move to the retracted position to make room for the transport vehicle 6;

[0068] S5: The transport vehicle 6 located on the ground 5 moves from the entrance and exit of the transport vehicle 6 to the bottom surface 4. The transport vehicle 6 stops directly under the vehicle. At this time, the comb plate 61 is in the low limit position.

[0069] S6: The comb plate 61 moves to its highest limit, and the vehicle is supported by the comb plate 61;

[0070] S7: Transport vehicle 6 carries the vehicle out of the hall through the entrance / exit of transport vehicle 6.

[0071] After S3 is completed and before S4 begins, centering push rod 31 is extended to move the vehicle on comb frame 3 laterally to the center, and then centering push rod 31 is retracted.

[0072] Example 2

[0073] The difference between this embodiment and embodiment one is that in this embodiment, the two transverse base frames 2 can be raised and lowered synchronously with the two comb frames 3.

[0074] Specifically, the front and rear ends of each transverse base frame 2 are fixed to the front and rear ends of each comb frame 3. Therefore, when the lifting mechanism 81 drives the comb frame 3 to move up and down along the vertical guide rail 8, the transverse base frame 2 will also move up and down along with the comb frame 3. At the same time, the transverse base frame 2 is connected to the guide frame of the comb frame 3 through a push-pull device. Moreover, in this embodiment, the end faces of the protruding and retracted ends of the first comb teeth cannot be provided with sealing plates. Instead, a crossbeam is provided on the bottom surface of the first comb teeth of the transverse base frame 2 to make the first comb teeth form a whole. In this way, the transverse base frame 2 will not interfere with the second comb teeth of the comb frame 3 when moving laterally. Furthermore, at this time, the first comb teeth may not be provided with the second roller 21, and shock-absorbing pads are provided below the comb teeth to protect the transverse base frame 2 when it descends to the bottom surface 4. Alternatively, the second roller 21 can be embedded in the first comb tooth, so that each set of second rollers 21 includes multiple second rollers 21 arranged in the left-right direction. When the centering push rod 31 is pushed out, it works together with the first roller 33 of the comb tooth frame 3 to assist the vehicle in moving laterally to the center of the car.

[0075] The present invention also provides a comb-tooth exchange parking method, comprising the following steps:

[0076] S1: The transverse base frame 2 extends to the extended position, and the comb frame 3 is in the low position, forming two travel platforms on the left and right sides;

[0077] S2: The vehicle enters the hall. The vehicle enters the hall from the vehicle entrance through the uphill ramp 7. At this time, the two wheels of the vehicle are supported on the left and right driving platforms respectively. The vehicle stops when the front wheels are blocked by the wheel chocks and enter the wheel drop groove.

[0078] S3: The comb frame 3 moves up to a high position, the vehicle is lifted, and the two transverse base frames 2 move up with the comb frame 3;

[0079] S4: The two transverse base frames 2 move to the retracted position to make room for the transport vehicle 6;

[0080] S5: The transport vehicle 6 located on the ground 5 moves from the entrance and exit of the transport vehicle 6 to the bottom surface 4. The transport vehicle 6 stops directly under the vehicle. At this time, the comb plate 61 is in the low limit position.

[0081] S6: The comb plate 61 moves to its highest limit, and the vehicle is supported by the comb plate 61;

[0082] S7: Transport vehicle 6 carries the vehicle out of the hall through the entrance / exit of transport vehicle 6.

[0083] After S3 is completed and before S4 begins, centering push rod 31 is extended to move the vehicle on comb frame 3 laterally to the center, and then centering push rod 31 is retracted.

[0084] In summary, the second roller 21 can have one or more of the following functions: if the transverse base 2 moves laterally in a low position, then the second roller 21 has the function of supporting the transverse base 2 on the bottom surface 4. At the same time, if the second roller 21 is embedded in the first comb tooth, it can also have the function of rolling support for the vehicle tires. If the transverse base 2 rises and falls synchronously with the comb tooth frame 3, then if the second roller 21 is embedded in the first comb tooth, it has the function of rolling support for the vehicle tires, and at the same time, it serves as a buffer support for the transverse base 2 when it lands. If the second roller 21 is set on the lower side of the transverse base 2, then it only has the function of buffer support for the transverse base 2 when it lands.
