Description

Technical Field

[0001] This invention relates to the field of automated parking system technology, specifically a highly secure comb-type automated parking system. Background Technology

[0002] With the development of the national economy and the improvement of people's living standards, the number of cars in Chinese cities has been increasing dramatically year by year. The increase in the number of cars in cities has not only put great pressure on urban road traffic, but also caused parking difficulties between roads. At the same time, with the gradual increase in the number of cars owned by individual families, the problem of parking difficulties in residential areas and the difficulty in finding parking spaces has also emerged. With the increase in demand, multi-level parking garages have emerged, and the comb-tooth tower-type multi-level parking garage is one of them.

[0003] Comb-type automated parking garages use combs to park and move vehicles. However, due to prolonged operation, they are prone to malfunctions, resulting in damage and misalignment of vehicles during parking. Therefore, structural improvements are needed to meet the requirements of long-term use. Furthermore, since the front and rear wheel tracks of vehicles are different, the spacing between the combs also needs to be adjusted. Conventional fixed comb designs are prone to vehicles slipping off, resulting in poor applicability and safety. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a highly safe comb-type multi-level parking system to solve the problems mentioned in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A highly secure comb-type multi-level parking system includes a garage frame, with a through circular trough at the center of the garage frame, and a liftable cross hydraulic lifting frame and a trailer frame inside the circular trough.

[0007] The trailer frame includes a circular lifting plate, the upper end of which is provided with a through movable groove, and both sides of the movable groove are provided with a first comb tooth fixedly connected and a second comb tooth slidably connected.

The front end of each third comb tooth is equipped with a liftable front end baffle. The three-link telescopic module includes a fixed frame, a first movable frame and a second movable frame. The second movable frame is equipped with a sliding block that is slidably engaged and a fixedly connected mounting block. The sliding block is equipped with a rotatably connected push rod, and the mounting block is equipped with a rotatably connected support rod.

[0009] Preferably, the garage frame has an array of outer ring frames and inner ring frames inside, and an axially arranged parking rack is provided between the outer ring frames and inner ring frames of each layer. The parking rack has a support groove inside, and an array of support comb teeth is provided on both sides of the support groove. The outer ring frame has an annular limiting groove inside.

[0010] Preferably, the garage frame is provided with a fixedly connected pre-stop frame on the side, and the upper end of the pre-stop frame is provided with an array of pre-stop comb teeth. Each set of pre-stop comb teeth can be raised and lowered, and the lower end of each pre-stop comb tooth is provided with a telescopic spring, and the telescopic spring is provided with a linear displacement sensor.

[0011] Preferably, a rotatably connected support disc is provided below the circular lifting plate, and the cross hydraulic lifting frame pushes the support disc and the circular lifting plate to rise and fall synchronously.

[0012] Preferably, the limiting guide includes a first hydraulic rod, a limiting frame, and a guide wheel. The telescopic end of the first hydraulic rod is fixedly connected to the limiting frame, and the guide wheel is installed inside the limiting frame and rotatably connected to it. The first hydraulic rod pushes the limiting frame and the guide wheel to extend out from between the circular lifting plate and the supporting plate, and the guide wheel is inserted into the limiting groove.

[0013] Preferably, each of the fourth comb teeth is provided with a sliding groove below it, and a sliding frame is provided in the sliding groove. The fourth comb tooth is slidably engaged with the sliding frame, and the height of the fourth comb tooth relative to the sliding frame can be adjusted by raising and lowering it.

[0014] Preferably, the vehicle retrieval frame is equipped with a third hydraulic rod, a fourth hydraulic rod, a fifth hydraulic rod, and a sixth hydraulic rod. The third hydraulic rod pushes the front end baffle to rise and fall. The fourth hydraulic rod is fixedly connected to the sliding frame. The sliding frame is equipped with a slidingly fitted first push rod. The telescopic end of the fourth hydraulic rod is rotatably connected to one end of the first push rod, and the other end of the first push rod is rotatably connected to the lower end of the fourth comb tooth. When the telescopic end of the fourth hydraulic rod moves, it drives the fourth comb tooth to rise and fall through the first push rod. The telescopic end of the fifth hydraulic rod is fixedly connected to the sliding frame and can pull the sliding frame and the fourth comb tooth to move.

[0015] Below the third comb tooth is a second push rod that can slide laterally. The telescopic end of the sixth hydraulic rod is rotatably connected to one end of the second push rod, and the other end of the second push rod is rotatably connected to the lower end of the third comb tooth. When the telescopic end of the sixth hydraulic rod moves, it drives the third comb tooth to rise and fall through the second push rod.

[0016] Preferably, a second motor is fixedly connected below the fixed frame, the first movable frame is slidably engaged with the upper surface of the fixed frame, the second movable frame is slidably engaged with the upper surface of the first movable frame, and the second motor is started to drive the first movable frame and the second movable frame to extend forward. The front end of the first movable frame is provided with a push wheel.

[0017] Preferably, the top end of the support rod is rotatably connected to the mounting block, and a torsion spring is provided at the rotatable part; the top end of the push rod is rotatably connected to the sliding block; the bottom end of the push rod is rotatably connected to the side of the support rod; the bottom end of the support rod is provided with a rotatably connected support wheel; and the push rod is in contact with the push wheel.

[0018] The beneficial effects of this invention are:

[0019] This invention provides a high-safety comb-type multi-level parking system that can automatically monitor vehicle dimensions and adjust the spacing of the comb teeth through an automatic device, thereby accommodating the loading and unloading of vehicles of different sizes. Furthermore, it can provide auxiliary support during vehicle loading and unloading, enhancing the overall safety of the parking garage operation.

[0020] In this invention, when the circular lifting platform reaches the same height as one of the parking racks, the first hydraulic rod pushes the limit frame and guide wheel to extend. The guide wheel is inserted into the limit groove. At this time, the first motor drives the circular lifting platform to rotate. The guide wheel can not only guide the rotation of the circular lifting platform, but also provide auxiliary support when the circular lifting platform moves vehicles in and out, avoiding the entire weight being pressed on the cross hydraulic lifting frame, thus improving the safety and stability when vehicles move in and out.

[0021] In this invention, the horizontal placement of the fourth and sixth hydraulic rods can effectively reduce the thickness of the vehicle retrieval frame, saving space. Furthermore, in the absence of external force, the torsion spring drives the support rod to remain perpendicular to the second movable frame. When the support rod is perpendicular, the support wheel contacts the support groove, thereby supporting the second movable frame and further increasing the stability and safety when retrieving and placing the vehicle.

[0022] When parking a car, the third hydraulic rod pushes the front baffle to rise and lift it up. Then, the switch door between the pre-parking frame and the parking frame opens, and the driver drives the vehicle from the pre-parking frame onto the parking frame. The tires press on the support comb teeth, and the car stops after the front wheels contact the front baffle. At this time, the front wheels of the car are above the third comb tooth, and the rear wheels are above the fourth comb tooth, which can effectively prevent the car from driving past the parking position.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 11 As shown, this embodiment provides a highly safe comb-type multi-level parking system, including a garage frame 1. A circular trough 11 is provided through the center of the garage frame 1. Inside the circular trough 11, there is a liftable cross hydraulic lifting frame 12 and a trailer frame 3. The cross hydraulic lifting frame 12 pushes the trailer frame 3 to rise and fall within the circular trough 11.

[0038] The garage frame 1 has an array of outer ring frames 13 and inner ring frames 14 inside. A parking rack 15 is arranged axially between the outer ring frames 13 and inner ring frames 14 of each layer. The parking rack 15 has a support groove 151 inside. The support groove 151 has an array of support comb teeth 152 on both sides. The outer ring frame 13 has an annular limiting groove 131 inside.

[0039] Furthermore, the garage frame 1 has a fixedly connected pre-parking rack 2 on its side. The pre-parking rack 2 is connected to the bottom set of parking racks 15. The upper end of the pre-parking rack 2 has an array of pre-parking comb teeth 21. Each set of pre-parking comb teeth 21 can be raised and lowered. The lower end of each pre-parking comb tooth 21 is equipped with a telescopic spring. The telescopic spring is equipped with a linear displacement sensor. When the car tires press on the pre-parking comb teeth 21, due to their own weight, the tires will press down on the pre-parking comb teeth 21. The distance between the front and rear tires of the car can be determined based on the pre-parking comb tooth 21 with the longest front and rear descent distance. The driver first drives the vehicle onto the pre-parking rack 2, and then the pre-parking comb teeth 21 measure the distance between the car tires. At this time, the cross hydraulic lifting rack 12 drives the trailer rack 3 to descend to the bottom set of parking racks 15 and then stops.

[0040] Furthermore, the trailer frame 3 includes a circular lifting plate 31. The upper end of the circular lifting plate 31 is provided with a through movable groove 311. The lower part of the circular lifting plate 31 is provided with a rotatably connected support plate 32 and a fixedly connected annular rack. The lower end of the support plate 32 is provided with a fixedly connected support connecting plate 321. The telescopic end of the cross hydraulic lifting frame 12 is connected to the support connecting plate 321. The cross hydraulic lifting frame 12 pushes the support plate 32 and the circular lifting plate 31 to rise and fall synchronously.

[0041] The support disc 32 and the circular lifting disc 31 are rotated and guided by a slewing bearing. The lower end of the support disc 32 is provided with a first motor 33 fixedly connected. The shaft of the first motor 33 is provided with a gear fixedly connected. The gear meshes with a ring rack. The first motor 33 drives the circular lifting disc 31 to rotate.

[0042] The lower end of the circular lifting plate 31 is also provided with an axially arranged limiting guide. The limiting guide includes a first hydraulic rod 34, a limiting frame and a guide wheel 341. The telescopic end of the first hydraulic rod 34 is fixedly connected to the limiting frame. The guide wheel 341 is installed inside the limiting frame and rotatably connected to it. The first hydraulic rod 34 can push the limiting frame and the guide wheel 341 to extend or retract between the circular lifting plate 31 and the supporting plate 32. When the circular lifting plate 31 reaches the same height as one of the parking racks 15, the first hydraulic rod 34 pushes the limiting frame and the guide wheel 341 to extend. The guide wheel 341 is inserted into the limiting groove 131. At this time, the first motor 33 drives the circular lifting plate 31 to rotate. The guide wheel 341 can not only guide the rotation of the circular lifting plate 31, but also provide auxiliary support when the circular lifting plate 31 is moving in and out of the vehicle, avoiding the entire weight being pressed on the cross hydraulic lifting frame 12, thus improving the safety and stability when the vehicle is moving in and out of the vehicle.

[0043] Both sides of the movable groove 311 are provided with a first comb tooth 312 fixedly connected and a second comb tooth 313 slidably connected. The circular lifting plate 31 is provided with a second hydraulic rod 314 fixedly connected inside. The telescopic end of the second hydraulic rod 314 is fixedly connected to the bottom end of the second comb tooth 313. The second hydraulic rod 314 pulls the second comb tooth 313 to move, thereby adjusting the distance between the second comb tooth 313 and the first comb tooth 312 to meet the parking needs of cars with different front and rear wheel tracks.

[0044] Furthermore, the movable groove 311 is equipped with a movable vehicle rack 4 and a three-link telescopic module 5. The vehicle rack 4 includes symmetrically arranged third comb teeth 41 and fourth comb teeth 43. The distance between the third comb teeth 41 and fourth comb teeth 43 is adjustable and they are pulled by a bidirectional hydraulic rod. The front end of each third comb tooth 41 is equipped with a liftable front baffle 44. Each fourth comb tooth 43 is equipped with a sliding groove 42 below it. A sliding frame 421 is provided in the sliding groove 42. The fourth comb tooth 43 slides with the sliding frame 421. The height of the fourth comb tooth 43 relative to the sliding frame 421 can be adjusted.

[0045] The vehicle retrieval frame 4 is equipped with a third hydraulic rod 441, a fourth hydraulic rod 45, a fifth hydraulic rod 46, and a sixth hydraulic rod 47. The third hydraulic rod 441 is perpendicular to the vehicle retrieval frame 4. The telescopic end of the third hydraulic rod 441 is fixedly connected to the front baffle 44. The third hydraulic rod 441 can push the front baffle 44 to rise and fall. The fourth hydraulic rod 45 is fixedly connected to the sliding frame 421. The sliding frame 421 is equipped with a slidingly engaged first push rod 451. The telescopic end of the fourth hydraulic rod 45 is rotatably connected to one end of the first push rod 451. The other end of the first push rod 451 is rotatably connected to the lower end of the fourth comb tooth 43. When the telescopic end of the fourth hydraulic rod 45 moves, it drives the fourth comb tooth 43 to rise and fall through the first push rod 451. The telescopic end of the fifth hydraulic rod 46 is fixedly connected to the sliding frame 421 and can pull the sliding frame 421 and the fourth comb tooth 43 to move.

[0046] Below the third comb tooth 41, there is a second push rod 471 that can slide laterally. The telescopic end of the sixth hydraulic rod 47 is rotatably connected to one end of the second push rod 471, and the other end of the second push rod 471 is rotatably connected to the lower end of the third comb tooth 41. When the telescopic end of the sixth hydraulic rod 47 moves, it drives the third comb tooth 41 to rise and fall through the second push rod 471. The horizontal placement of the fourth hydraulic rod 45 and the sixth hydraulic rod 47 can effectively reduce the thickness of the vehicle rack 4 and save space.

[0047] Furthermore, the three-link telescopic module 5 includes a fixed frame 51, a first movable frame 52, and a second movable frame 53. A second motor 511 is fixedly connected below the fixed frame 51, and a first drive belt is provided around the outside of the fixed frame 51. The second motor 511 drives the first drive belt to rotate cyclically. The first movable frame 52 is slidably engaged with the upper surface of the fixed frame 51 through a slide rail slider assembly. The first movable frame 52 is fixedly connected to the first drive belt through a fixing member. A second drive belt is provided around the outside of the first movable frame 52 and can rotate. The second movable frame 53 is slidably engaged with the upper surface of the first movable frame 52 through a slide rail slider assembly. The second drive belt is connected to the fixed frame 51 and the second movable frame 53 through fixing members respectively. When the second motor 511 is started, it can drive the first movable frame 52 and the second movable frame 53 to extend forward. A push wheel 521 is provided at the front end of the first movable frame 52.

[0048] The second movable frame 53 has a sliding block 531 that is slidably engaged and a mounting block 532 that is fixedly connected. The sliding block 531 has a push rod 55 that is rotatably connected, and the mounting block 532 has a support rod 54 that is rotatably connected. The top end of the support rod 54 is rotatably connected to the mounting block 532, and a torsion spring is provided at the rotation point. When there is no external force, the torsion spring drives the support rod 54 to keep it perpendicular to the second movable frame 53. The top end of the push rod 55 is rotatably connected to the sliding block 531, and the bottom end of the push rod 55 is rotatably connected to the side of the support rod 54. The bottom end of the support rod 54 has a support wheel 541 that is rotatably connected. When the support rod 54 is vertical, the support wheel 541 contacts the support groove 151, thereby supporting the second movable frame 53. When the second movable frame 53 is fully extended, the torsion spring can drive the support rod 54 to rotate vertically. When the second movable frame 53 retracts, the push rod 55 contacts the push wheel 521, and the push wheel 521 pushes the push rod 55 to rotate and rise. The push rod 55 drives the support rod 54 to reverse and retract for storage.

[0049] Working principle:

[0050] When in use, the driver drives the car onto the pre-stop frame 2. When the car tires press on the pre-stop comb teeth 21, due to their own weight, the tires will press down on the pre-stop comb teeth 21. Then the pre-stop comb teeth 21 measure the distance between the car tires. At this time, the cross hydraulic lifting frame 12 drives the trailer frame 3 to descend to the lowest parking frame 15 and then stops. The second hydraulic rod 314 pulls the second comb teeth 313 to move, and the fifth hydraulic rod 46 pulls the fourth hydraulic rod 45 and the fourth comb teeth 43 to move. The second comb teeth 313 and the fourth comb teeth 43 stop after moving to the designated position length. The second motor 511 starts to drive the first moving frame 52 and the second moving frame 53 to move forward and extend. When the second moving frame 53 is fully extended, the torsion spring can drive the support rod 54 to rotate vertically. When the support rod 54 is vertical, the support wheel 541 contacts the support groove 151. The three-link telescopic module 5 drives the car pick-up frame 4 to move forward to above the round support comb teeth 152 and then stops.

[0051] Then, the fourth hydraulic rod 45 drives the fourth comb tooth 43 to descend, and the sixth hydraulic rod 47 drives the third comb tooth 41 to descend. The fourth comb tooth 43 and the third comb tooth 41 insert into the gap between the supporting comb tooth 152. The third hydraulic rod 441 pushes the front baffle 44 to rise and lift it up. Then, the door between the pre-stop frame 2 and the parking frame 15 opens, and the driver drives the vehicle from the pre-stop frame 2 onto the parking frame 15. The tires press on the supporting comb tooth 152, and the car stops after the front wheels contact the front baffle 44. At this time, the front wheels of the car are above the third comb tooth 41, and the rear wheels are above the fourth comb tooth 43. Then, the fourth hydraulic rod 45 drives the fourth comb tooth 43 to descend. As tooth 43 rises, the sixth hydraulic rod 47 drives the third comb tooth 41 to rise. The third comb tooth 41 and the fourth comb tooth 43 lift the car. The three-link telescopic module 5 drives the vehicle retrieval frame 4 and the car back to the initial position. The support rod 54 retracts. At this time, the third comb tooth 41 and the fourth comb tooth 43 are above the first comb tooth 312 and the second comb tooth 313. Then the third comb tooth 41 and the fourth comb tooth 43 descend, and the car tires land on the first comb tooth 312 and the second comb tooth 313. Then the cross hydraulic lifting frame 12 drives the trailer frame 3, the vehicle retrieval frame 4, the three-link telescopic module 5 and the car to rise. After reaching the designated parking height, it stops.

[0052] The first hydraulic rod 34 pushes the limit frame and guide wheel 341 to extend. The guide wheel 341 is inserted into the limit groove 131. The first motor 33 drives the circular lifting plate 31 to rotate and adjust the angle. After the angle adjustment is completed, the third comb tooth 41 and the fourth comb tooth 43 rise and lift the car. The three-link telescopic module 5 drives the car retrieval frame 4 and the car to move forward to the designated parking rack 15. Then the third comb tooth 41 and the fourth comb tooth 43 descend, and the car tires fall on the supporting comb tooth 152. Then the third comb tooth 41 and the fourth comb tooth 43 retract into the car retrieval frame 4. Then the car retrieval frame 4 is removed and left.
