Description

Technical Field

[0001] The utility model belongs to the technical field of parking garage equipment and relates to a balanced rotating double-deck parking garage. Background Technique

[0002] With the increasing number of household cars, the problem of parking difficulty is very common. As a result, various types of three-dimensional parking garages have emerged, and most of their structures are lift and cross-move types, which are suitable for construction in public places and have a large parking capacity. However, for the scenarios with narrow passages and many curves in residential communities, most three-dimensional parking garages are difficult to adapt to. Therefore, the side-position double-deck three-dimensional parking garage has emerged.

[0003] Chinese Patent (Patent No. CN202220725819.4, Publication Date (Authorization): July 22, 2022) discloses "a non-hydraulic double-deck parking space device". This parking garage occupies a small space, but its disadvantage is that the upper-layer vehicle must drive out of the garage for the lower-layer vehicle to enter or exit, so the entry and exit of upper and lower-layer vehicles are inconvenient and time-consuming. Chinese Patent (Application No. CN201010268293.3, Publication Date (Publication): January 12, 2011) discloses "a double-deck three-dimensional parking garage". Its disadvantage is that the swing rod under the upper parking position plate needs to rotate 90 degrees from horizontal to three-dimensional, and the hydraulic pull rod contracts. It is not convenient to install and must rely on a firm side wall for fixation to withstand the pulling force of the vehicle weight, which is not conducive to popularization in small spaces. Content of the Utility Model

[0004] The purpose of the utility model is to provide a balanced rotating double-deck parking garage, which solves the problems that it is difficult to build a parking garage in a narrow position and it is not easy to achieve double-deck parking in the prior art.

[0005] For the balanced rotating double-deck parking garage, one side-entry garage structure includes a side-entry rack. The upper part and the side facing the road center line of the side-entry rack are open. A pair of swing column balance mechanisms one are symmetrically installed on the front and rear end faces of the main body of the side-entry rack along the vehicle length direction. A set of rotating balance mechanisms are installed at the ends of each set of swing column balance mechanisms one. Two side-entry hanging baskets are jointly installed between the two sets of rotating balance mechanisms. A driving route one is jointly configured for the pair of swing column balance mechanisms one, and a driving route two is configured for the rotating balance mechanism. The control mechanism includes a controller and an operation panel. All reduction motors are connected to the control mechanism.

[0006] For the balanced rotating double-deck parking garage, another side-entry garage structure includes a side-entry rack. Swing column balance mechanisms two and a figure-eight retractable rotating balance mechanism one are installed on the front and rear end faces of the main body of the side-entry rack along the vehicle length direction. The swing column balance mechanisms two are set as a pair, and the figure-eight retractable rotating balance mechanism one is set as a pair. A sprocket synchronization component is also arranged on one of the figure-eight retractable rotating balance mechanism one.

[0007] The balanced rotating double-layer parking garage belongs to a direct-entry garage. The structure of this direct-entry garage includes a direct-entry rack. The top of the direct-entry rack and one end of the longitudinal entry are open. A translation mechanism and a horizontally arranged "day" - shaped retractable rotating balance mechanism II are provided in the direct-entry rack.

[0008] The structure of the translation mechanism is as follows: Double-layer beam tracks are arranged on the upper parts of both sides of the direct-entry rack. Track grooves are installed in the double-layer beam tracks. A sliding shaft seat is slidably arranged in the track grooves. The sliding shaft seat is integrally connected with a speed reducer. The sliding shaft seat and the speed reducer are integrally hinged to the translation hydraulic cylinder for pushing and pulling the sliding.

[0009] The beneficial effects of the present utility model are as follows: It realizes double-layer three-dimensional parking. The overall floor area of the parking garage is small. It is convenient for vehicles to enter and exit the parking spaces. The vertical position arrangement is reasonable and has good stability. It is suitable for installation in small spaces such as the roadside of residential areas, narrow curved roads, and alleys, especially suitable for scenarios where the height cannot exceed the limit in narrow roadways or underground parking lots.

Detailed implementation mode

[0028] The present utility model will be described in detail below in conjunction with the accompanying drawings and the detailed implementation mode.

[0029] The "upper, lower, left, and right" directions involved in the following text are intuitive descriptions for the corresponding drawings and do not limit the installation positions of the components in the device structure. The actual installation positions are analogized accordingly.

[0030] The structure of the device of the utility model is divided into two types, namely, side-entry garage and direct-entry garage, according to the entry mode of vehicles and parking spaces. After two vehicles in the side-entry garage are parked in place, the side of each vehicle is parked parallel to the back frame (side wall) of the side-entry rack 1, and parking is completed; after two vehicles in the direct-entry garage are parked in place, the head and tail direction of each vehicle is parked close to the inner end surface (back wall) of the side-entry rack 1, and parking is completed.

[0031] Embodiment 1: A side-entry garage corresponding to a pendulum balancing mechanism 1 and a rotational balancing mechanism.

[0032] Reference Figure 1 The structure of the side-entry garage of the utility model device is that it includes a side-entry frame 1, the main body of the side-entry frame 1 is a rectangular frame, and a side of the rectangular frame close to the outside of the road (or close to the roadside wall) can also be optionally provided with a raised back frame, and the upper side of the side-entry frame 1 and the side facing the center line of the road are open, so as to facilitate the up-down exchange, rotation and exchange of positions of two side-entry hanging baskets; a pair of pendulum column balancing mechanisms 1 are symmetrically installed on the front and rear ends of the main body of the side-entry frame 1 along the length direction of the vehicle, and a set of rotating balancing mechanisms is installed at the end of each set of pendulum column balancing mechanisms 1, and two side-entry hanging baskets are installed between the two sets of rotating balancing mechanisms; a pair of pendulum column balancing mechanisms 1 are jointly equipped with a driving route 1, which is powered by a reduction motor 1; the rotating balancing mechanism is equipped with a driving route 2, which is powered by a reduction motor 2; (a tension sensor assembly is also provided on the driving route 2 of the rotating balancing mechanism), and the control mechanism includes a controller and an operation panel; all (sensors) and reduction motors are connected to the control mechanism, and work in coordination to realize the entry and exit of the two side-entry hanging baskets, the up-down position conversion and the parking state locking.

[0033] Two reduction motors are fixedly installed on the back frame of the side-entry frame 1, wherein reduction motor 1 realizes the swing function of pendulum column balancing mechanism 1 (marked by pendulum column 9) through driving route 1, and reduction motor 2 realizes the rotation function of rotation balancing mechanism (marked by pry plate beam 1 23) through driving route 2.

[0034] See Figure 1 The structure of the pendulum balancing mechanism is that the drive line is used, including a reduction motor, the reduction motor is connected to the long transmission shaft 2, and the two ends of the long transmission shaft 2 are further divided into two transmission branches, that is, at the two ends of the long transmission shaft 2 (i.e. Figure 1One driving sprocket 3 is fixedly installed respectively along the front - rear direction in which the vehicle is parked. The driving sprocket 3 at each end is in transmission connection with a driven sprocket 5 through a first chain 4. The driven sprocket 5 is coaxially and fixedly connected with a driving gear 7 through a connecting shaft 6. The driving gear 7 is meshed and connected with a sector gear 8. The sector gear 8 is further hinged to the upper part of a swing rod column 9. The lower part of each swing rod column 9 is hinged to a swing rod column seat 10 through a first pin shaft 11. The swing rod column seat 10 is fixed on the side - entry frame 1, realizing the lateral swing (taking the vehicle front - rear direction as the longitudinal direction) of each swing rod column 9 with the hinged swing rod column seat 10 as the axis. The above components are called a set of swing column balance mechanism one. A set of swing column balance mechanism one is respectively arranged at the longitudinal two ends of the side - entry frame 1. The two sets of swing column balance mechanism one in total coordinate and synchronously swing laterally, realizing that when the vehicle is parked up and down, it approaches or leaves the back frame of the side - entry frame 1 simultaneously, leaving enough space for the up - down balanced rotation of the rotation balance mechanism and not colliding with the back frame during the rotation process.

[0035] See Figure 1 、 Figure 5 For each swing rod column 9, a set of parallel frames is also configured. The two parallel frames are symmetrically arranged along the front - rear direction in which the vehicle is parked. The structure of each parallel frame is as follows: it includes a lower horizontal rod. The swing rod column seat 10 itself serves as the fixed lower horizontal rod. A first hinge seat 26 and a second hinge seat 27 are respectively arranged laterally along the swing rod column seat 10. The first hinge seat 26 is hinged upward with a first parallel pull rod 28. The other end of the first parallel pull rod 28 is further hinged to one end of a horizontal rod 30. The second hinge seat 27 is hinged upward with a second parallel pull rod 29. The other end of the second parallel pull rod 29 is further hinged to the other end of the horizontal rod 30. The swing rod column seat 10, the first parallel pull rod 28, the second parallel pull rod 29, and the horizontal rod 30 together form a set of parallel frames, and this set of parallel frames is used to lock the balance of the balance shaft 13.

[0036] Refer to Figure 2 、 Figure 3The structure of the rotating balancing mechanism is that a fixing sleeve 31 is installed on the upper part of the rocker column 9, and a balancing shaft 13 is passed through the center of the shaft hole of the fixing sleeve 31. The balancing shaft 13 is set in the hole of the fixing sleeve 31 and can rotate freely; the balancing shaft 13 is fixedly connected to the horizontal rod 30 (to ensure that the balancing shaft 13 does not rotate), and the horizontal rod 30 is not connected to the fixing sleeve 31. A large gear 22 is set on the fixing sleeve 31, and a chain link pry plate beam 1 23 is fixed on the inner side of the large gear 22. A long fixed shaft 1 24 and a long fixed shaft 2 25 are installed between a pair of pry plate beams 1 23; the large gear 22 is meshed and connected with the gear 2 21, and the gear 2 21 is connected to the gear 2 through the reduction gear set 20 and the reduction gear set 21. The gear set 19 is connected to the gear 18 in transmission, and the gear 18 is coaxially fixedly connected to the driven sprocket 2 17 through the lower transmission shaft 12. The lower transmission shaft 12 is sleeved in the axial hole of the pin shaft 11 at the lower part of the rocker column 9. The driven sprocket 2 17 is connected to the driving sprocket 2 15 through the chain 2 16. The driving sprocket 2 15 is connected to the reduction motor 2 in driving connection. A pair of driving sprockets 2 15 symmetrically arranged along the front and rear directions of the parked vehicle are fixedly connected to a long transmission shaft 2 14. The above transmission route is called drive route 2, which realizes the synchronous rotation of a pair of pry plate beams 23 on the upper part of the rocker column 9 (also called pry plate beam balancing mechanism).

[0037] The inner side of the balancing shaft 13 is also equipped with a balancing sprocket 1 32 and a balancing sprocket 2 35. The balancing sprocket 1 32 is connected to the hanging basket sprocket 1 34 through a balancing chain 1 33. The hanging basket sprocket 1 34 is coaxially fixedly connected to the bearing seat 382 of the side-entry hanging basket 1 38. The hanging basket sprocket 1 34 and the connected bearing seat 382 are both slidably mounted on the long fixed shaft 1 24 to ensure that the bottom plate of the side-entry hanging basket 1 38 is always parallel to the ground; the balancing sprocket 2 35 is connected to the hanging basket through a balancing chain 2 36. The sprocket 2 37 is connected for transmission, the hanging basket sprocket 2 37 is coaxially fixedly connected with the bearing seat of the side-entry hanging basket 2 39, the hanging basket sprocket 2 37 and the connected bearing seat are slidably mounted on the long fixed shaft 25, ensuring that the bottom plate of the side-entry hanging basket 2 39 is always parallel to the ground, preventing the side-entry hanging basket 1 38 with the vehicle and the side-entry hanging basket 2 39 from tilting, the above structure is called a hanging basket balancing mechanism, and the hanging basket balancing mechanism can be set with only one set, which is installed on the inner side of the skid plate beam 1 23 at one end close to the reduction motor 2;

[0038] The basket balancing mechanism cooperates with the driving route 2 to ensure that the two side-entry baskets rotate with the pair of skid beams 23 while ensuring that the bottom plates of the two side-entry baskets always remain horizontal with the ground, preventing the vehicles in the two side-entry baskets from tilting. Under the coordination of the controller, the vehicles remain stable during entry and exit and parking.

[0039] Reference Figure 4, at both longitudinal ends of the rectangular side-entry rack 1, a swing rod column 9 is installed respectively. On each swing rod column 9, a pry plate beam one 23 is installed. Between the two pry plate beams one 23, two side-entry hanging baskets are installed correspondingly. The structures and sizes of the side-entry hanging basket one 38 and the side-entry hanging basket two 39 are the same. Each side-entry hanging basket includes a bottom plate. At the front and rear ends of the bottom plate, load-bearing arms 381 with arched doorways are symmetrically arranged. The arched doorways of the load-bearing arms 381 facilitate the entry and exit of vehicles. The load-bearing arms 381 at both ends of the bottom plate are symmetrically inclined upward and outward, presenting an inverted V shape relatively. At the center position of the top of each load-bearing arm 381, a load-bearing seat 382 is fixed. A pair of load-bearing seats 382 at both ends of the side-entry hanging basket one 38 are sleeved on the long fixed shaft two 25 through a pair of bearings. A pair of load-bearing seats at both ends of the side-entry hanging basket two 39 are similarly sleeved on the long fixed shaft one 24 through another pair of bearings correspondingly.

[0040] Refer to Figure 5 , Figure 6 , on the chain two 16 of the rotary balance mechanism, a tension sensor assembly is arranged. By monitoring the tension state of the chain two 16, the weights of the newly stored vehicles and the original in-stock vehicles can be confirmed. The structure of the tension sensor assembly is as follows: it includes a sprocket swing rod 42. The sprocket of the sprocket swing rod 42 is lapped on the chain two 16. The rod end of the sprocket swing rod 42 is in contact with the tension sensor 44 correspondingly. The tension sensor 44 is fixed on the back frame of the side-entry rack 1. A tension spring 43 is connected to the middle of the sprocket swing rod 42. The other end of the tension spring 43 is fixed on the side-entry rack 1. The signal wire of the tension sensor 44 is connected to the controller. (Or, a mass sensor is arranged on the bottom plate of each side-entry hanging basket to detect the total mass of the parked vehicle, replacing the tension sensor assembly to judge the weights of the two parked vehicles, so that the controller can determine the parking operation with the light vehicle on top and the heavy vehicle at the bottom).

[0041] For the side-entry garage of the present utility model, based on the structures associated with the above-mentioned swing column balance mechanism one and the rotary balance mechanism, and using the tension sensor assembly, the working principle is as follows:

[0042] 1) Operation of the vehicle leaving the warehouse. First, start the deceleration motor one. Through the drive of the drive route one, the outward swing of the swing rod column 9 is realized, and the two hanging baskets leave the back frame by a predetermined distance at the same time. Then, in accordance with the principle that the side-entry hanging basket of the vehicle to be taken out of the warehouse takes the shortest path, start the deceleration motor two to rotate forward or rotate. On the premise that any side-entry hanging basket will not collide with the back frame, through the drive of the drive route two, the pry plate beam one 23 rotates to a 45-degree inclined position. The side-entry hanging basket of the vehicle to be taken out of the warehouse stops stably on the ground. The vehicle to be taken out of the warehouse drives out, and the operation of taking out of the warehouse is completed. See Figure 1 Or Figure 9 .

[0043] 2) Parking operation of the incoming vehicle (assuming regardless of weight). After the incoming vehicle enters a side-entry hanging basket on the ground, first, the second deceleration motor starts. Through the second drive route, it drives the first pry bar beam 23 to rotate counterclockwise. The newly incoming vehicle takes the shortest route to ensure that the two hanging baskets remain horizontal when following the rotation until the two hanging baskets are vertically aligned. At this time, the second long transmission shaft 14 is driven by a turbine deceleration motor or a brake motor and will automatically lock the rotation of the second long transmission shaft 14. The first pry bar beam 23 is locked in a vertical state, and the two hanging baskets are vertically fixed and aligned. See Figure 7 . Then, the first deceleration motor drives the swing rod column 9 to swing outward through the first drive route until the two hanging baskets approach the back frame at the same time until the incoming positions of the two side-entry hanging baskets reach the final parking state. See Figure 8 .

[0044] 3) For newly incoming vehicles or when there is no incoming vehicle (assuming the weight needs to be discriminated), the tension sensor 44 is used to detect the tension state of the upper section of the second chain 16 to determine whether the mass of the newly incoming vehicle exceeds the mass of the vehicle already in the warehouse. The comparison of the masses of the two vehicles is respectively called a light vehicle and a heavy vehicle. Through the detection of the tension sensor assembly, in accordance with the principle that the side-entry hanging basket with a lighter mass (or an empty hanging basket) takes the shortest route and automatically switches to the high position, the parking of the two side-entry hanging baskets is controlled, including the following four working conditions:

[0045] Working condition 1, see Figure 5 , if the total mass of the newly incoming vehicle is less than the total mass of the vehicle already in the warehouse, and it is confirmed that it belongs to the situation where a light vehicle enters, then the side-entry hanging basket where the original vehicle in the warehouse is located has a tendency to sink, driving the two side-entry hanging baskets to have a tendency to rotate clockwise. This torsional tendency shown by the first pry bar beam 23 is manifested on the second chain 16 through the second drive route. Since the second long transmission shaft 14 is automatically locked by the transmission method of the turbine deceleration motor or the brake deceleration motor, it will cause the lower section of the second chain 16 to be tightened and the upper section to be slack. Then the tension sensor 44 will sense the slack tension of the upper section and send the information of the light vehicle to the controller, and the controller will issue an instruction to continue rotating clockwise. The operation process is: first start the second deceleration motor, use the second drive route to drive the first pry bar beam 23 to rotate clockwise again until the two side-entry hanging baskets reach the vertically corresponding positions. At this time, the two side-entry hanging baskets have not approached the back frame of the side-entry rack 1. See Figure 7 ; then, start the first deceleration motor again, the first drive route works, and the swing rod column 9 is under the drive control of the first long transmission shaft 2. Through swinging, the two side-entry hanging baskets approach the back frame of the side-entry rack 1 at the same time to complete the side parking and locking inward, without occupying the road space outside the side-entry rack 1. The final parking state is as Figure 8 .

[0046] Working condition 2, see Figure 6If the total mass of the newly entered vehicle is greater than the total mass of the vehicles already in the warehouse, and it is confirmed that it is a heavy-duty vehicle entering the side-entry basket, then the side-entry basket where the vehicle is located will tend to tilt upward, driving the two side-entry baskets to rotate counterclockwise. This torsional tendency of the pry plate beam 23 is reflected on the chain 2 16 through the drive route 2. Since the long drive shaft 2 14 is locked by the transmission method of the turbine reducer motor or the brake reducer motor, the upper section of the chain 2 16 will be tightened and the lower section will be relaxed. The tension sensor 44 will feel the tension of the upper section and send the heavy-duty vehicle information to the controller. The controller will issue an instruction to continue to rotate counterclockwise. The operation process is: first, start the reducer motor 2, and the reducer motor 2 drives the long drive shaft 2 14 to rotate counterclockwise until the two baskets correspond to each other up and down, and the two baskets are not close to the back frame of the side-entry rack 1. Figure 7 Then, the reduction motor 1 is started, and the swing rod column 9 is controlled by the transmission route of the long transmission shaft 2, and the two hanging baskets are swung to the back frame of the side-entry rack 1, and the side parking is completed and locked inside, without occupying the road space outside the side-entry rack 1. The final parking state is as follows Figure 8 .

[0047] Working condition three, if the mass of the newly entered vehicle is substantially the same as that of the already entered vehicle, the controller defaults to the skid beam 23 rotating counterclockwise, that is, the side entry basket where the newly entered vehicle is located directly enters the low position, so that the displacement of the two side entry baskets is minimal, and parking is completed by the shortest route.

[0048] Working condition 4: if a vehicle in a hanging basket leaves the warehouse and no new vehicle enters the warehouse, it is equivalent to the weight comparison result of working condition 1. The controller defaults to the pry plate beam 23 rotating clockwise, that is, the side entry hanging basket where the original vehicle in the warehouse is located is converted into a low position, ensuring that the side entry hanging basket with the parked vehicle is in a low position, which is beneficial to the safety and stability of the parked vehicles and makes the stress of related components in a relatively relaxed state.

[0049] 4) The controller is also equipped with an operation panel to realize automatic operation of loading and unloading. The controller pre-stores the control process based on the above four vehicle parking conditions. The control functions of the relevant "buttons" on the control panel corresponding to the controller are as follows:

[0050] "High position outbound" button, when the vehicle to be outbound has been parked at a high position, the operation process is: first control the swing column 9 to swing outward, so that the two side-entry hanging baskets leave the back frame of the side-entry rack 1 at the same time by a predetermined distance, and then move the high-position side-entry hanging basket in a counterclockwise direction to the landing position, and the vehicle in the side-entry hanging basket completes the outbound;

[0051] For the "low-level exit" button, when the vehicle to be exited has already been parked at a low level, the operation process is as follows: First, control the swing rod column 9 to swing outward, so that the two side-entry hanging baskets simultaneously leave the back frame of the side-entry rack 1 by a predetermined distance. Then, move the hanging basket at the low level clockwise to the landing position, and the vehicle in the side-entry hanging basket completes the exit.

[0052] For the "entry" button, when the mass of the newly entered vehicle is greater than that of the existing vehicles in the warehouse, the operation process is as follows: The controller determines that the side-entry hanging basket of the newly entered vehicle moves counterclockwise to the low level until the two hanging baskets leave the back frame of the side-entry rack 1 by a predetermined distance. Then, control the swing rod column 9 to swing inward to complete the entry and parking. Or, when the mass of the newly entered vehicle is less than that of the existing vehicles in the warehouse, the controller determines that the side-entry hanging basket of the newly entered vehicle moves clockwise to the high level until the two hanging baskets leave the back frame of the side-entry rack 1 by a predetermined distance. Then, control the swing rod column 9 to swing inward to complete the entry and parking.

[0053] For the "recovery" button, when a vehicle exits but no new vehicle enters, the operation process is as follows: When there is only one original vehicle in the warehouse, control the empty side-entry hanging basket to move clockwise to the high level, and move the side-entry hanging basket with a vehicle clockwise to the low level until the two hanging baskets leave the back frame of the side-entry rack 1 by a predetermined distance. Then, control the swing rod column 9 to swing inward to complete the low-level parking of one vehicle. When both side-entry hanging baskets are in an empty state, they move counterclockwise until the two hanging baskets leave the back frame of the side-entry rack 1 by a predetermined distance. Then, control the swing rod column 9 to swing inward, and both empty side-entry hanging baskets are in a parked state.

[0054] The control panel can also be set with other relevant operation buttons to achieve the strategic control of different ways of vehicle entry and exit.

[0055] Embodiment 2: The side-entry garage adopts a structure related to the swing column balance mechanism II and the "day"-shaped contraction and rotation balance mechanism.

[0056] If heavy sedans (in this utility model, specifically referring to sedans with a total mass of not less than 2 tons) need to be parked frequently, the structural strength of the aforementioned side-entry garage is difficult to handle the double-layer parking of heavy sedans. Therefore, the structure of the side-entry garage in Embodiment 2 includes a side-entry rack 1. On the front and rear end faces of the main body of the side-entry rack 1 along the vehicle length direction, a pair of swing column balance mechanisms II and a longitudinally arranged "day"-shaped contraction and rotation balance mechanism are symmetrically installed. A pair of swing column balance mechanisms II are provided, and a pair of "day"-shaped contraction and rotation balance mechanisms are provided. A sprocket synchronization component is also provided on one of the "day"-shaped contraction and rotation balance mechanisms.

[0057] Refer to Figure 9, the structure of the pendulum column balancing mechanism II is that a T-shaped arm is arranged on the outer side of the upper part of the pendulum rod column 9. One short side of the T-shaped arm on the upper part of the pendulum rod column 9 is hinged to the bottom end of the cylinder body of the hydraulic jack 64 through the pin shaft II 60. The piston rod end of the hydraulic jack 64 is hinged to the lifting rod 65. The upper end of the lifting rod 65 is hinged to the upper part of the side column of the side entry frame 1 through the connecting rod I 66. The lower end of the lifting rod 65 is hinged to the lower part of the side column of the side entry frame 1 through the connecting rod II 67. The lifting rod 65, the connecting rod I 66, the connecting rod II 67 and the side column of the side entry frame 1 are hinged to form a parallelogram linkage mechanism to realize the up and down swing of the lifting rod 65. The other short side of the T-shaped arm on the upper part of the pendulum rod column 9 is hinged to the piston rod end of the hydraulic pull cylinder 62 through the pin shaft III 61. The cylinder body end of the hydraulic pull cylinder 62 is hinged to the back frame of the side entry frame 1 through the pin shaft IV 63. The middle upper part of the T-shaped long arm of the pendulum rod column 9 is hinged to the transmission rod 72. The other end of the transmission rod 72 is hinged to the pendulum rod II 70 through the pin shaft VI 71. The pendulum rod II 70 is hinged to the pendulum rod seat II 68 through the pin shaft V 69. The pendulum rod seat II 68 is fixed on the side entry frame 1. The pendulum rod II 70 is fixedly connected to the semi-circular large gear 73. The teeth on the outer surface of the semi-circular large gear 73 are meshed and connected to the gear III 74. The gear III 74 is fixedly sleeved on the long transmission shaft I 2. The long transmission shaft I 2 is drivingly connected to the reduction motor I, which is called the transmission route III. The hydraulic pull cylinder 62 and the hydraulic jack 64 jointly assist the reduction motor I to enable a pair of pendulum rod columns 9 to swing synchronously and lift and lower at the same time, facilitating the forward or reverse rotation of the daily-shaped contraction and rotation balancing mechanism.

[0058] Refer to Figure 10 , Figure 11The structure of the "日"-shaped contraction and rotation balancing mechanism is that it includes a pair of "日"-shaped balancing components, one of which is also provided with a sprocket synchronization component, and each "日"-shaped balancing component is installed on the inner large gear 22 of the swing rod column 9 at one end; the structure of one of the "日"-shaped balancing components is that it includes a central plate beam 45, the intermediate shaft hole of the central plate beam 45 is sleeved on the balancing shaft 13 on the upper part of the swing rod column 9, and the central plate beam 45 is fixed as a whole with the large gear 22, and is driven along the aforementioned driving route 2; the two ends of the central plate beam 45 are respectively hinged with a pry plate beam 2 48 and a pry plate beam 3 49, and the two ends of the pry plate beam 2 48 and the pry plate beam 3 49 are respectively hinged with a parallel beam 2 47 and a parallel beam 48 146, parallel beam 247, parallel beam 146, pry plate beam 248 and pry plate beam 349 together form a parallelogram structure; the hinge of pry plate beam 248 and parallel beam 146 is provided with a long rod hole 152, a long fixed shaft 124 is passed through the long rod hole 152, and a side-entry hanging basket 239 is hung; the hinge of pry plate beam 349 and parallel beam 247 is provided with a long rod hole 25, a long fixed shaft 25 is passed through the long rod hole 251, and a side-entry hanging basket 38 is hung; the hinge of parallel beam 146 and pry plate beam 349 is provided with a pin shaft 759, the pin shaft 759 is hinged to the bottom end of the cylinder body of telescopic hydraulic cylinder 50, and the piston rod end of telescopic hydraulic cylinder 50 is hinged to the pin shaft 889 in the middle of pry plate beam 248;

[0059] In addition, a sprocket synchronization assembly is also provided on one of the "日"-shaped balancing assemblies. The structure of the sprocket synchronization assembly is that it includes a balancing sprocket 1 32 and a balancing sprocket 2 35 which are coaxially fixedly installed with the balancing shaft 13. The balancing sprocket 1 32 is transmission connected to the inner sprocket 1 57 through an inner chain 1 56, the inner sprocket 1 57 is coaxially and integrally connected to the outer sprocket 1 55, and the outer sprocket 1 55 is transmission connected to the hanging basket sprocket 1 34 through a balancing chain 1 33; the balancing sprocket 2 35 is also transmission connected to the outer sprocket 2 54 through an outer chain 2 58, the outer sprocket 2 54 is coaxially fixed to the inner sprocket 2 53, and the inner sprocket 2 53 is connected to the hanging basket sprocket 2 37 through a balancing chain 2 36, thereby realizing synchronous control of the two side-entry hanging baskets, ensuring that the bottom plates of the two side-entry hanging baskets are level and the vehicles are parked stably.

[0060] Under the action of the driving route two, the center plate beam 45 rotates together with the large gear 22. By means of the sprocket synchronization assembly, the change in the distance between the first long rod hole 52 and the second long rod hole 51 in the figure-eight-shaped balance assembly is adjusted. The interval positions of the two side-entry hanging baskets change with the rotation distance of the center plate beam 45, ensuring the minimum outer contour during the up-and-down position conversion and reducing the collision risk with surrounding components. At the same time, under the telescopic action of the telescopic hydraulic cylinder 50, the second pry bar beam 48 and the third pry bar beam 49 in the figure-eight-shaped balance assembly move parallel and in opposite directions, and the distance between the first long rod hole 52 and the second long rod hole 51 changes accordingly, also ensuring the minimum outer contour of the two side-entry hanging baskets and preventing them from colliding with the back frame.

[0061] See Figure 9 , the hydraulic jack cylinder 64 extends to the end, and the lifting rod 65 unfolds and lands to support the swing rod column 9. The hydraulic pull cylinder 62 extends to play an auxiliary role in pulling the swing rod column 9, causing the swing rod column 9 to swing outward to the limit position (a certain distance away from the back frame); then, the figure-eight-shaped retractable rotary balance mechanism starts to rotate forward or backward until the side-entry hanging basket to be stored or retrieved lands; thus, the vehicle can be stored or retrieved.

[0062] When a light vehicle enters the side-entry hanging basket, the controller defaults to rotate clockwise, and the swing rod column 9 of the second swing column balance mechanism is lifted. The controller automatically rotates the two hanging baskets to the position where they overlap vertically. Only during the clockwise rotation process does it pass through Figure 12 this state.

[0063] After the vehicle is stored or retrieved, the side-entry hanging baskets of the newly stored or retrieved vehicle rotate forward or backward with the figure-eight-shaped retractable rotary balance mechanism. When the two side-entry hanging baskets reach the overlapping position vertically, the figure-eight-shaped retractable rotary balance mechanism is locked; then, the hydraulic pull cylinder 62 contracts, and the hydraulic jack cylinder 64 contracts to drive the lifting rod 65 to fold off the ground. The second swing column balance mechanism acts, and the swing rod column 9 swings inward until the swing rod column 9 swings inward to the limit position (close to the back frame), completing the parked state, see Figure 13 .

[0064] The above-mentioned pair of figure-eight-shaped balance assemblies are suitable for the parking of heavy vehicles. There are two telescopic hydraulic cylinders 50, hydraulic pull cylinders 62, and hydraulic jack cylinders 64 respectively, so as to ensure that the forces applied to the two end side-entry hanging baskets are consistent and the lifting is stable and the actions are synchronous. The telescopic hydraulic cylinder 50, hydraulic pull cylinder 62, and hydraulic jack cylinder 64 are all powered by a hydraulic pump, and a hydraulic control mechanism is used to achieve coordinated actions. There is only one set of sprocket synchronization assembly, and the hydraulic pump and controller are not shown in the drawings.

[0065] The aforementioned two reduction motors, hydraulic pump, and hydraulic control mechanism are all connected to the controller, facilitating the manual button operation by the user on the control panel.

[0066] For heavy vehicles, the working principle of the enhanced swing column balance mechanism II and the side-entry garage of the H-shaped contraction and rotation balance mechanism of the present utility model is as follows:

[0067] 1) The working mode of the H-shaped balance assembly is that the central plate beam 45 is fixedly connected to the large gear 22. The swing column balance mechanism II swings to the extreme position close to the road center line, and then, under the contraction and pulling of the H-shaped contraction and rotation balance mechanism and the telescopic hydraulic cylinder 50, the distance between the first long rod hole 52 and the second long rod hole 51 becomes the longest. The whole H-shaped balance assembly forms a 45-degree angle with the ground, and one side-entry hanging basket is in the ground-contact position, and the vehicle completes the entry and exit of the garage. See Figure 9 ;

[0068] 2) When the vehicle completes the exit from the garage and a new vehicle enters the garage, if the total mass of the newly entered vehicle is less than that of the original vehicle in the garage, the controller implements control according to the principle of placing the heavier vehicle at a lower position. Rotate the H-shaped balance assembly in the clockwise direction, the hydraulic jack cylinder 64 extends, and the lifting rod 65 lands on the ground to achieve ground support; then, the hydraulic jack cylinder 64 continues to extend, and at the same time the hydraulic pull cylinder 62 retracts, jointly pulling the H-shaped balance assembly to rotate clockwise, and rotating the two hanging baskets to the horizontal side-by-side position. See Figure 12 ; then, the telescopic hydraulic cylinder 50 extends, and the distance between the first long rod hole 52 and the second long rod hole 51 becomes shorter, and the two side-entry hanging baskets are not likely to collide with the back frame of the side-entry rack 1 during the rotation process; after the two side-entry hanging baskets rotate to the upper and lower positions, then drive the swing rod column 9 to swing, and the swing rod column 9 starts to swing towards the back frame of the side-entry rack 1, and the two side-entry hanging baskets approach the back frame of the side-entry rack 1 at the same time to complete parking. See Figure 13 .

[0069] 3) When the vehicle completes the exit from the garage and a new vehicle enters the garage, if the total mass of the newly entered vehicle is greater than that of the original vehicle in the garage, the controller rotates the H-shaped balance assembly according to the counterclockwise principle, and controls the side-entry hanging basket of the heavier vehicle to be placed at a lower position nearby. The hydraulic jack cylinder 64 pushes out the lifting rod 65 to land on the ground to achieve ground support; then, the hydraulic jack cylinder 64 slightly contracts, and the hydraulic pull cylinder 62 also retracts, jointly pulling the H-shaped balance assembly to rotate clockwise by a small angle, so that the hanging basket where the newly entered vehicle is located leaves the ground by a predetermined height; then, the telescopic hydraulic cylinder 50 extends, the hydraulic jack cylinder 64 continues to contract, and the hydraulic pull cylinder 62 also continues to retract, and the distance between the first long rod hole 52 and the second long rod hole 51 becomes shorter, and the two hanging baskets approach each other so that they are not likely to collide with the back frame of the side-entry rack 1 during the rotation process until the two hanging baskets rotate to the upper and lower overlapping positions; then control the swing of the swing rod column 9, and the swing rod column 9 starts to swing towards the back frame of the side-entry rack 1, and the two hanging baskets approach the back frame of the side-entry rack 1 at the same time to complete parking. See Figure 13 .

[0070] 4) When the vehicle has completed entering and exiting the garage and there is no new vehicle entering the garage, the controller rotates the figure-eight balance assembly in a clockwise direction, that is, it implements control according to the principle that the hanging basket with a vehicle is placed at a low position. The hydraulic jack cylinder 64 retracts, and the hydraulic pull cylinder 62 retracts, jointly pulling the figure-eight balance assembly to rotate clockwise. First, the two hanging baskets are rotated to the horizontal side-by-side position, as shown in Figure 12 ; then, the telescopic hydraulic cylinder 50 extends, and the distance between the long rod hole one 52 and the long rod hole two 51 becomes shorter. The two hanging baskets approach each other so that they are not easily hit against the back frame of the side entry rack 1 during the rotation process until the two hanging baskets are rotated to the upper and lower overlapping positions; then, the swing of the swing rod column 9 is controlled, and the swing rod column 9 starts to swing towards the back frame of the side entry rack 1. The two hanging baskets approach the back frame of the side entry rack 1 at the same time to complete parking, as shown in Figure 13 .

[0071] Embodiment 3: A direct-entry garage, including a translation mechanism and a figure-eight contraction and rotation balance mechanism two arranged transversely corresponding thereto.

[0072] If at the end of a road or in a dead-end of a parking lot (commonly known as a dead end), which is suitable for a direct-driving scenario, a structural layout of a direct-entry garage is required. The vehicle can directly drive in or reverse into it to complete parking.

[0073] Based on the concept of the foregoing Embodiment 2, the structure of the direct-entry garage re-sets a new translation mechanism and re-arranges the figure-eight contraction and rotation balance mechanism two transversely to meet the need for the vehicle to directly enter and exit.

[0074] Referring to Figure 14 , Figure 17 , the structure of the direct-entry garage is as follows. It includes a direct-entry rack 75. The top of the direct-entry rack 75 and one end of the longitudinal entry are open (in the front and rear end directions, facilitating the vehicle to directly drive in or reverse into the direct-stop hanging basket). On the upper parts of both sides of the direct-entry rack 75, there are track-type double beams. A track groove 78 is installed in the track-type double beams. A sliding shaft seat 77 is slidably arranged in the track groove 78. The sliding shaft seat 77 is integrally arranged with a speed reducer 76. The sliding shaft seat 77 and the speed reducer 76 are integrally hinged and pushed and pulled by a translation hydraulic cylinder 86 to realize the integral horizontal sliding of the sliding shaft seat 77 and the speed reducer 76. While the two direct-stop hanging baskets in the figure-eight balance assembly rotate up and down in balance, the whole moves in or out towards the inner frame against the wall, completing the overall entry or overall exit of the two hanging baskets, which is called the translation mechanism;

[0075] Referring to Figure 14 , Figure 15 , Figure 16, the rectangular-shaped contraction and rotation balance mechanism II is arranged horizontally. That is, in the parking mode of this Embodiment 3, the in-out direction of the directly parked hanging basket I 87 is perpendicular to the long fixed shaft I 24. Similarly, the in-out direction of the directly parked hanging basket II 88 is perpendicular to the long fixed shaft II 25. The lengths of the long fixed shaft I 24 and the long fixed shaft II 25 are significantly less than the width of the directly entering rack 75; an inner side of each sliding shaft seat 77 is supported and installed with a rectangular-shaped balance assembly, and a pair of rectangular-shaped balance assemblies are symmetrically installed relative to each other. One of the rectangular-shaped balance assemblies is provided with the aforementioned sprocket synchronization assembly. The balance sprocket I 32 and the balance sprocket II 35 in the sprocket synchronization assembly are coaxial and fixedly connected to the balance shaft 13 together. The balance shaft 13 is fixed in the sliding shaft seat 77 (adopting key connection); the central plate beam 45 in each rectangular-shaped balance assembly is fixedly connected to the large gear 22. The large gear 22 is movably sleeved on the balance shaft 13. The large gear 22 is meshed and connected with the driving small gear 79. The driving small gear 79 is transmission-connected to the spline long transmission shaft 80 through the speed reducer 76. The driving small gear 79 and the speed reducer 76 are both installed on the sliding shaft seat 77 (driving the pair of rectangular-shaped balance assemblies to translate and maintaining the horizontal stability of the two directly parked hanging baskets through the sprocket synchronization assembly at the same time). The spline long transmission shaft 80 is slidably coaxially sleeved with the transmission pipe 81 (coaxial rotation can be maintained during the telescopic process between the two). A sprocket 82 is coaxially fixed at the end of the transmission pipe 81. The sprockets 82 are arranged on both inner ends of the directly entering rack 75. A linkage transmission chain 83 is commonly connected between the sprockets 82 on both sides to achieve synchronous rotation. One of the sprockets 82 is further driven and connected to the reduction motor III 85 through the main transmission chain 84, which is called the driving route IV; all components of the driving route IV and all components of the rectangular-shaped balance assembly together form the rectangular-shaped contraction and rotation balance mechanism II.

[0076] One reduction motor III 85 is provided, and both the telescopic hydraulic cylinder 50 and the translation hydraulic cylinder 86 are two. Under the coordinated control of the controller, the translation and rotation of the rectangular-shaped balance assembly are synchronously realized to achieve vehicle out-of-warehouse and in-warehouse.

[0077] In the structure of the directly entering garage of this Embodiment 3, the forward or reverse rotation of the driving route IV realizes the balanced rotation and displacement of the rectangular-shaped balance assembly, and then, in cooperation with the telescopic of the telescopic hydraulic cylinder 50 in the rectangular-shaped balance assembly, the adjustment of the up-and-down positions of the two vehicles is completed; the contraction of the translation hydraulic cylinder 86 realizes that the rectangular-shaped balance assembly approaches the inner frame end of the parking garage (equivalent to the back frame of the directly entering garage) to complete vehicle parking, or the extension of the translation hydraulic cylinder 86 makes the rectangular-shaped balance assembly move outwards to prepare for vehicle in-out-of-warehouse.

[0078] The working principle of the directly entering garage of this Embodiment 3 is that the control principle is similar to that of the aforementioned Embodiment 1. Auxiliary equipment for judging the weights of the two parked vehicles can be configured. According to the principle that the light vehicle is on the top and the heavy vehicle is on the bottom, and taking into account the principle of taking the shortest stroke during the balanced rotation process, vehicle in-out-of-warehouse is realized and parking is completed.

[0079] Among the above three structures of the present utility model, the stepping reduction motor, the hydraulic motor and the reduction motor can be replaced with each other to achieve power-load matching. In addition, the turbine reduction motor or the brake motor has an automatic locking function and is preferably used.

The balance shaft (13) is fixed in the sliding shaft seat (77). The central plate beam (45) in each rectangular balance component is fixedly connected to the large gear (22). The large gear (22) is movably sleeved on the balance shaft (13). The large gear (22) is meshed and connected to the driving pinion (79). The driving pinion (79) is transmission-connected to the splined long transmission shaft (80) through the speed reducer (76). Both the driving pinion (79) and the speed reducer (76) are installed on the sliding shaft seat (77). The splined long transmission shaft (80) is slidably and coaxially sleeved with the transmission pipe (81). A sprocket (82) is coaxially fixed at the end of the transmission pipe (81). The sprocket (82) is arranged on both sides of the inner end of the straight-in frame (75). A linkage drive chain (83) is commonly connected between the sprockets (82) on both sides. One of the sprockets (82) is further drive-connected to the reduction motor three (85) through the main drive chain (84).
