Description

Technical Field

[0001] The invention belongs to the technical field of parking equipment, and in particular relates to a three-dimensional parking garage capable of charging cars. Background Art

[0002] With the rapid development of science and technology and the improvement of living standards, the use of cars has become more and more widespread, and driving has become an indispensable need for people. In recent years, the number of cars has grown rapidly, but the average growth rate of urban roads is far less than the growth rate of cars. In particular, the number of cars in large cities far exceeds the capacity of parking infrastructure, resulting in a serious shortage of parking garages in many cities. Against the background of rapid increase in the number of cars and limited parking space, three-dimensional parking garages have developed rapidly. Three-dimensional parking garages can park twice or even more cars in one parking garage. Therefore, the construction of three-dimensional parking garages can double the number of parking lots without expanding the area, which can effectively solve the problem of parking difficulties in cities.

[0003] However, the current three-dimensional parking garage still has the following problems:

[0004] A multi-story parking garage consists of several layers of parking units. Usually, the parking units on the upper layer need to be moved up and down through vertical guide rails, columns and other motion mechanisms, resulting in a relatively complex structure of the current multi-story parking garage. Due to structural limitations, multi-story parking garages can only be fixed in a certain three-dimensional space and cannot move out of the space. However, in most cases, the parking garage and the cars that have not entered the garage are perpendicular to each other, and complex reversing actions are required to enter or exit the garage.

[0005] Therefore, it is necessary to provide a three-dimensional parking garage that can charge cars, so that the actions of entering and exiting the car are more flexible and simple. Summary of the invention

[0006] 1. Technical issues to be resolved

[0069] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0070] The present invention provides a three-dimensional parking garage capable of charging cars, comprising a first-floor parking unit, a second-floor parking unit, a shear lifting mechanism 1 and a guide rail mechanism.

[0071] The upper end of the shear lifting mechanism 1 is fixedly connected to the second-floor parking unit to adjust the height of the second-floor parking unit relative to the first-floor parking unit. The three-dimensional parking garage of the present invention adjusts the height of the second-floor parking unit relative to the first-floor parking unit through the shear lifting mechanism to achieve the folding of the second-floor parking unit and the first-floor parking unit, avoiding the setting of complex vertical guide rails and columns and other components, and the structure is more lightweight, which can avoid blocking the surrounding space of the parking garage. In addition, since the three-dimensional parking garage of the present invention does not have structures such as columns and vertical guide rails, the height requirement of the parking garage can be reduced by about 30 mm, and the applicable parking garage height is wider. The three-dimensional parking garage of the present invention can be installed on a personal parking space, turning one parking space into two, thereby increasing the car accommodating capacity.

[0072] In the present invention, the lower end of the shear lifting mechanism can be connected in two ways, one is fixedly connected to the ground of the parking garage, and the other is fixedly connected to a parking unit on the first floor. The two connection methods are specifically described in Example 1 and Example 2.

[0073] When the lower end of the shear lift mechanism is fixedly connected to the ground of the parking garage, the guide rail mechanism is extended along the axial direction of the parking garage, including a linear guide rail and a curved guide rail. The parking unit of one layer can move along the linear guide rail and rotate and reverse along the curved guide rail to adjust the direction to be consistent with the car before parking. The car can be parked by simply driving forward in a straight line, making the car entry operation easier. The "axial direction" mentioned in this embodiment refers to Figure 1 as well as Fig. 9 The direction of the dotted line corresponding to the multi-story parking garage when it has not moved.

[0074] When the lower end of the shear lift mechanism is fixedly connected to the first-floor parking unit, the guide rail mechanism is also extended along the axial direction of the parking garage. The shear lift mechanism 1 and the second-floor parking unit can follow the first-floor parking unit to move along the linear guide rail, and the driving structure rotates and reverses the direction with the connection between the first-floor parking unit and the guide rail mechanism as the rotation axis, and adjusts the direction to be consistent with the car before parking. The car can be parked by simply driving forward in a straight line, making the car entry operation easier.

[0075] The shear lifting mechanism 1 of the present invention comprises two mutually intersecting shear arms 2 and a push-pull mechanism 3 for adjusting the angle between the shear arms.

[0076] The upper ends of the two shear arms 2 are connected to the second-floor parking unit, and the lower ends of the two shear arms 2 are connected to the first-floor parking unit or to the ground of the parking garage.

[0077] The push-pull mechanism 3 is arranged at the top end of the shear arm 2 or the bottom end of the shear arm 2, and the push-pull mechanism 3 can be a hydraulic cylinder.

[0078] The three-dimensional parking garage of the present invention further includes a charging mechanism 4, which can be a DC charging device or an AC charging device. The charging mechanism 4 is provided in both the first-floor parking unit and the second-floor parking unit, and is electrically connected to an external power source, such as a distribution box. The charging mechanism in the present invention can be directly connected to the distribution box via a cable, without the need for a complex cable adapter.

[0079] New energy vehicles, such as electric vehicles, are developing rapidly, and the number of electric vehicles is increasing. Electric vehicles need to be charged after use. However, in the actual use of the three-dimensional parking garage in the prior art, the number of floors of each parking unit is not completely fixed. In different parking scenarios, the number of floors of the same parking unit may have changed compared to the last parking scenario. Therefore, the current three-dimensional parking garage has a poor charging effect on electric vehicles, because the cable access to each parking unit is not fixed, which makes charging troublesome.

[0080] In the present invention, although there is relative movement in the height direction between the second-floor parking unit and the first-floor parking unit, the second-floor parking unit is always located below the first-floor parking unit, and the upper and lower position relationship is fixed. Therefore, the present invention can set a fixed charging mechanism in the three-dimensional parking garage, and connect the charging mechanism to an external power source through a cable, so that the electric vehicle can be charged without complicated cable replacement. The three-dimensional parking garage of the present invention can be applied to electric vehicles, meet the charging needs of electric vehicles, and realize simple charging.

[0081] The specific composition and installation of the above-mentioned shear lifting mechanism and charging mechanism are applicable to both Example 1 and Example 2.

[0082] Example 1

[0083] like Figure 1-Figure 6 As shown, this embodiment provides a charging three-dimensional parking garage, including a first-floor parking unit, a second-floor parking unit, a shear lifting mechanism 1 and a guide rail mechanism.

[0084] The upper end of the shear lifting mechanism 1 is fixedly connected to the second-floor parking unit to adjust the height of the second-floor parking unit relative to the first-floor parking unit.

[0085] In this embodiment, the lower end of the shear lift mechanism 1 is fixedly connected to the ground of the parking garage, and the shear lift mechanism 1 and the second-floor parking unit can only move up and down in the parking garage and cannot move along the guide rail mechanism.

[0086] Preferably, if Figure 1-Figure 2 As shown, the guide rail mechanism in this embodiment includes a first linear guide rail 13 and a curved guide rail 14. The first linear guide rail 13 is located in the middle of the parking garage and extends axially along the parking garage, and the curved guide rail 14 is connected to one end of the first linear guide rail 13. The first linear guide rail 13 and the curved guide rail 14 are both embedded in the ground of the parking garage, and their surfaces are flush with the ground where the parking garage is located.

[0087] The cross-sections of the first linear guide 13 and the curved guide 14 are U-shaped or I-shaped. The first linear guide 13 and the curved guide 14 include C-shaped steel or I-shaped steel. The C-shaped steel or I-shaped steel has internal connecting racks and wire grooves, and the wire grooves and the C-shaped steel or I-shaped steel form guide grooves.

[0088] Preferably, if Figure 4 As shown, the parking unit on one floor includes a loading plate 11, a driving wheel 15, a first guide wheel 16, a first universal wheel 17 and a load-bearing wheel 18. During the movement and rotation of the parking unit on one floor, the driving wheel 15 meshes with the rack and moves along the rack. The first guide wheel 16 includes two, which are respectively distributed at the front and rear ends of the driving wheel, and are connected with the wire groove and the C-shaped steel or I-shaped steel to form a guide groove, and slide along the groove to achieve a positioning and guiding effect.

[0089] The driving wheel 15 is arranged at the bottom of the first layer of the vehicle loading plate 11 and is connected to the power component. The driving wheel 15 moves along the first linear guide rail 13 and the rack in the curved guide rail 14 under the drive of the power component, such as the driving motor, so as to drive the parking unit of the first layer to move along the guide rail mechanism. The driving motor is connected to the external power supply through a cable.

[0090] The first guide wheel 16 is engaged with the guide groove formed inside the first linear guide rail 13 and the curved guide rail 14, and slides along the guide groove to ensure the running direction of the parking unit on the first layer and the vehicle loading plate 11 on the first layer. The first universal wheel 17 is arranged at the bottom of both sides of the vehicle loading plate 11 on the first layer, and serves as a load-bearing component of the parking unit on the first layer during the movement and rotation along the guide rail mechanism, and bears the gravity from the parking unit on the first layer. Figure 3 as well as Figure 6 As shown, the load-bearing wheels 18 are arranged at the bottom of a layer of vehicle loading plate 11 near the front end and on both sides of the central axis of the moving direction of the layer of vehicle loading plate, and are used to bear the load at the front of a layer of parking units.

[0091] In this embodiment, the parking unit on the first floor is moved by the first linear guide rail 13, and is driven by the driving component to rotate and change direction along the curved guide rail 14. In this embodiment, taking the parking garage and the lane as an example, the parking unit on the first floor is rotated 90° on the curved guide rail. In actual use, the curvature of the curved guide rail 14 can be set according to the specific situation of the angle between the parking garage and the lane, so that the car can directly drive to the first floor vehicle loading plate 11 after the parking unit on the first floor is rotated.

[0092] In this embodiment, the parking method of the car is as follows:

[0093] S1: The second-floor loading plate 12 is raised by the shear lifting mechanism 1, and a travel signal is issued, and the first-floor parking unit moves out of the parking garage along the first linear guide rail 13, and then a rotation signal is issued, and the first-floor parking unit rotates along the curved guide rail 14, so that the direction of the first-floor loading plate 11 is parallel to the direction of the car. The driver directly enters the car on the first-floor loading plate 11 and completes the parking of the first-floor parking unit without complicated operations such as reversing.

[0094] S2: The second-layer vehicle loading plate 12 is lowered to the lowest position by the shear lifting mechanism 1. After the lowering is completed, the height of the entire three-dimensional parking garage does not exceed 120 mm. The car is backed into the second-layer vehicle loading plate 12 according to the ordinary backing action.

[0095] S3: After the parking of the second-floor parking unit is completed and the second-floor loading plate 12 is raised to the specified height, a reverse rotation signal and a backward signal are issued, and the first-floor parking unit rotates in the opposite direction to the original position along the curved guide rail 14, and then returns to the parking garage along the first linear guide rail 13, completing the entry of the upper and lower floors of the three-dimensional parking garage.

[0096] The vehicles entering the above-mentioned first-floor parking unit and second-floor parking unit can be carried out independently without interfering with each other.

[0097] In this embodiment, the method for a car to exit the three-dimensional parking garage is as follows:

[0098] S1: A travel signal is issued, and the parking unit on the first floor moves out of the parking garage along the first linear guide rail 13. Then a rotation signal is issued, and the parking unit on the first floor rotates along the curved guide rail 14, so that the direction of the first floor loading plate 11 is parallel to the direction of the car lane. The driver directly drives the car out of the first floor loading plate 11 and completes the exit of the parking unit on the first floor without complicated reversing operations.

[0099] S2: After the parking unit on the first floor is unloaded, a reverse rotation signal and a backward signal are issued, and the parking unit on the first floor rotates in the opposite direction to the original position along the curved guide rail 14, and then returns to the parking garage along the original route along the first linear guide rail 13.

[0100] S3: The second-layer vehicle loading plate 12 is lowered to the lowest position by the shear lifting mechanism 1. After the lowering is completed, the height of the entire three-dimensional parking garage does not exceed 120 mm. The car is driven out of the second-layer vehicle loading plate 12 according to the ordinary driving action to complete the vehicle exit of the second-layer parking unit.

[0101] The vehicles in the first-floor parking unit and the second-floor parking unit mentioned above can be dispatched independently without interfering with each other.

[0104] The upper end of the shear lifting mechanism 1 is fixedly connected to the second-floor parking unit to adjust the height of the second-floor parking unit relative to the first-floor parking unit.

[0105] In this embodiment, the lower end of the shear lift mechanism 1 is fixedly connected to the first-floor parking unit. In this embodiment, there is only an adjustment of the vertical distance between the shear lift mechanism 1 and the second-floor parking unit and the first-floor parking unit, and there is no relative movement in the horizontal plane. Therefore, the entire three-dimensional parking garage in this embodiment, including the first-floor parking unit and the second-floor parking unit, can move and rotate synchronously along the guide rail mechanism.

[0106] like Figure 7 as well as Fig.12 As shown, the guide rail mechanism in this embodiment is a second linear guide rail 24, which is located in the middle of the parking garage and extends axially along the parking garage.

[0107] The first-floor parking unit includes a running mechanism 22 and a chassis 23. Specifically, the running mechanism 22 is fixedly connected to the chassis 23, and the running mechanism 22 can drive the chassis 23 to move forward or backward along the second linear guide rail 24. In addition, the running mechanism 22 can also drive the chassis 23 to rotate along the central axis of the running mechanism 22, and rotate to a suitable angle according to the position of the car before parking, so that the whole three-dimensional parking garage is parallel to the car, and the car can be directly driven into the upper parking unit of the three-dimensional parking garage to achieve entry and exit, without complicated reversing actions, and easy operation.

[0108] Preferably, if Figure 13-14 As shown, the second linear guide rail 24 includes a C-shaped steel 241 , a rack 242 and a wire groove 243 .

[0109] The C-shaped steel 241 is fixed on the ground of the parking garage, and its upper end surface is flush with the ground of the parking garage. The rack 242 and the wire groove 243 are installed in the C-shaped steel 241. Specifically, the rack 242 and the wire groove 243 are both connected to the C-shaped steel 241, and the wire groove 243 is located below the rack 242.

[0110] Preferably, the rack 242 can be installed horizontally inside the C-shaped steel 241, or vertically inside the C-shaped steel 241. Fig.13 As shown, the "horizontal" in this embodiment means that each tooth in the rack 242 is facing upward. Fig.14 As shown, the "vertical" in this embodiment refers to each tooth in the rack 242 facing the side wall of the C-shaped steel on the opposite side. In the following content, the rack 242 is arranged horizontally, and the vertical arrangement is not repeated.

[0111] Preferably, if Figure 15-16 As shown, the operating mechanism 22 includes a controller, a driving component, a rotating platform 221 , a walking wheel 222 and a second guide wheel 223 .

[0112] The driving component is connected to the rotating table 221 and the running wheel 222, the controller is electrically connected to the driving component, the rotating table 221 is connected to the chassis 23, the running wheel 222 cooperates with the rack 242 in the second linear guide rail 24, and the second guide wheel 223 is engaged with the guide groove 244 formed by the C-shaped steel 241 and the wire groove 243 in the second linear guide rail 24, and slides along the guide groove 244 to ensure the travel direction of the three-dimensional parking garage and prevent derailment.

[0113] The driving component includes a rotating motor and a driving motor. The rotating motor is connected to the rotating platform 221 through a reduction box, and the driving motor is connected to the walking wheel 222 through a reduction box. The rotating motor and the driving motor in this embodiment are connected to an external power source through a cable.

[0114] After the controller receives the travel instruction, the driving motor drives the walking wheel 222 to move along the rack 242, so that the operating mechanism 22 moves forward or backward along the second linear guide rail 24, and the overall movement of the three-dimensional parking garage is realized. After the controller receives the rotation instruction, the rotating motor drives the rotating table 221 and the chassis 23 connected to the rotating table to rotate, thereby driving the entire first-floor parking unit and the second-floor parking unit to rotate, and adjusting the first-floor parking unit and the second-floor parking unit to a suitable entry or exit angle. In this embodiment, taking the parking garage and the lane as an example, the first-floor parking unit rotates 90° on the second linear guide rail 24. In actual use, the operating mechanism 22 can rotate according to the specific situation of the angle between the parking garage and the lane, so that the car can directly drive to the upper loading plate 21 after the first-floor parking unit rotates.

[0115] Preferably, if Fig.17 As shown, the chassis 23 includes side beams 232 , a front beam 231 , a towing turntable 233 and a second universal wheel 234 .

[0116] The front beam 231 is E-shaped, and includes two side beams 232 . The two side beams 232 are arranged in parallel and are respectively connected to two sides of the front beam 231 .

[0117] The dragging turntable 233 is connected to the middle of the front beam 231 , the dragging turntable 233 is connected to the rotating platform 221 , and the second universal wheel 234 is connected to the bottom of the side beam 232 .

[0118] Specifically, the upper end surface of the rotating platform 221 is a flange structure, the dragging rotating platform 233 is a flange structure, and the rotating platform 221 is flange-connected to the dragging rotating platform 233 .

[0119] In this embodiment, the chassis 23 is a flat structure, and its internal space can park a car. When the second-floor parking unit is fully lowered, the overall height of the three-dimensional garage is less than 120 mm, which is lower than the minimum ground clearance of the car, and the car can be parked smoothly. In this embodiment, the side beam 232 is a bearing mechanism that bears the load of the operating mechanism 22. Therefore, the side beam 232 needs to be made of high-strength alloy. The dragging turntable 233 is a traction mechanism, which is the traction point for the movement and rotation of the entire chassis, and the dragging and rotation are achieved through the power of the operating mechanism.

[0120] In this embodiment, the method for a car to enter a three-dimensional parking garage is as follows:

[0121] S1: A travel signal is sent, and the operating mechanism 22 drives the parking unit of one layer and the upper loading plate 21 to move along the second linear guide rail 24. Then a rotation signal is sent, and the operating mechanism 22 drives the parking unit of one layer and the upper loading plate 21 to rotate about 90°, so that the direction of the upper loading plate 21 is parallel to the direction of the car.

[0122] S2: The upper loading plate 21 is lowered to the lowest position by the shear lifting mechanism 1. After the lowering is completed, the height of the entire three-dimensional parking garage does not exceed 120 mm. The driver directly enters the car on the upper loading plate 21 to complete the parking of the second-floor parking unit without complicated operations such as reversing.

[0123] S3: After the parking of the second-floor parking unit is completed, the second-floor parking unit is raised, and a reverse rotation signal and a backward signal are issued. The operating mechanism 22 drives the first-floor parking unit and the upper vehicle loading plate 21 to rotate in the opposite direction to the original position as a whole, and then returns along the second linear guide rail 24 to realize the overall return of the three-dimensional parking garage, and then the vehicle is loaded into the first-floor parking unit according to the ordinary reversing method.

[0124] The above-mentioned first-floor parking unit and second-floor parking unit can be entered independently without interfering with each other. In this embodiment, the method for a car to exit the three-dimensional parking garage is as follows:

[0125] S1: Carry out the car dispatch from the parking unit on the first floor according to the normal dispatch operation.

[0126] S2: After the parking unit on the first floor has finished moving out, a travel signal is sent out, and the operating mechanism 22 drives the parking unit on the first floor and the upper loading plate 21 to move along the second linear guide rail 24. After reaching a certain position, the operating mechanism 22 drives the parking unit on the first floor and the upper loading plate 21 to rotate about 90°, so that the direction of the upper loading plate 21 is roughly parallel to the direction in which the car needs to move out.

[0127] S3: The upper loading plate is lowered to the lowest position by the shear lifting mechanism 1. After the lowering is completed, the height of the entire three-dimensional parking garage does not exceed 120 mm. The driver directly drives the car to the upper loading plate 21 to complete the parking of the second-floor parking unit without complicated operations such as reversing.

[0128] S4: After the second-floor parking unit has been unloaded, the operating mechanism 22 drives the first-floor parking unit and the upper-floor vehicle loading plate 21 to rotate in the opposite direction to the original position as a whole, so that the three-dimensional parking garage returns as a whole.

[0129] The vehicles in the first-floor parking unit and the second-floor parking unit mentioned above can be dispatched independently without interfering with each other.

[0130] Therefore, this embodiment mainly realizes a simpler and more convenient exit and entry action in the second-floor parking unit by moving and rotating the second-floor parking unit as a whole, thereby improving the user experience. When the second-floor parking unit is in a stationary state, both sides of the first-floor parking unit bear the weight of the second-floor parking unit. When the second-floor parking unit is in motion, especially in a rotating state, the rotation process will generate lateral force, so the first-floor and second-floor parking units maintain a good overall balance during the rotation process. For this reason, Fig.12 As shown, in this embodiment, a flat and wide connector 25 with a large cross-sectional stiffness is provided at the front section of the first-floor parking unit, and a balance beam is provided at the upper rear side of the second-floor parking unit (located below the second-floor vehicle loading plate, not shown in the figure). The balance beam is perpendicular to the linear motion direction of the second-floor parking unit, and the force is applied by the combination of the connector 25 and the balance beam, which greatly improves the overall stability of the parking garage.

[0131] In addition, no vehicle loading plate is provided in the first-floor parking unit in this embodiment. Compared with the first embodiment, the structure of the three-dimensional parking garage is simpler and more flexible.

[0132] The above embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention. Those skilled in the art may make various deformations or modifications within the scope of the claims, which belong to the essential content of the present invention.
