Description

Technical Field

[0001] The present invention relates to the technical field of mechanical stereo garages, and in particular to a parking device, a parking system and a method for a four-way transversely movable vehicle loading plate. Background Art

[0002] Currently, parking difficulties remain a persistent problem in older residential communities in urban centers. These communities were built earlier, have high population densities, and are often limited in number of parking spaces. With the increasing prevalence of private cars, this difficulty has become even more pronounced. Among the various types of mechanical parking garages, horizontal circulation garages allow for the free movement of vehicles within the garage plane. These garages offer a small footprint, high parking density, and short construction times, making them ideal for older communities with high parking densities.

[0003] However, existing horizontal circulation parking garages have complex mechanical structures, high construction costs, and are difficult to popularize. For example, the patent announcement number CN109642433B, named parking rack, parking device and lifting rack, specifically discloses that "it is used to store parking pallets for placing vehicles and transport parking pallets in the transverse and longitudinal directions. The parking rack has: conveying wheels arranged at the four corners of the rectangle of the shelf frame, the rectangle has two sides parallel to the transverse direction and two sides parallel to the longitudinal direction of the shelf frame; a conveying drive for rotating a pair of conveying wheels located on the diagonal of the rectangle; a pair of first connecting rods and a pair of second connecting rods for connecting the four conveying wheels into a rectangle; and a wheel steering mechanism for synchronously orienting the conveying wheels." In the above-mentioned prior art, the guide rail steering mechanism of the horizontal circulating parking pallet (i.e., the loading plate) is integrated at the bottom of the loading plate, resulting in a complex structure of the loading plate and high manufacturing cost; at the same time, the main load-bearing beam node inside the loading plate needs to be cut off to set the steering shaft system, and the main load-bearing beam node inside the loading plate needs to be cut off to set the steering guide rail. Under the same main load-bearing beam design height, the overall strength of the loading plate itself is greatly reduced, making it difficult to carry heavier vehicles. This limits the overall cost and performance indicators of horizontal circulation garages, and has a significant impact on their marketability.

[0004] In addition, when the loading plate is moved horizontally to the position of the loading frame, it needs to be accurately positioned. Only when the supporting roller groups are aligned with the guide rail steering mechanism at the bottom of the loading plate can they be rotated simultaneously to drive the steering; if there is a certain position error between the loading plate and the parking frame, the supporting roller groups are likely to get stuck when rotating, resulting in the equipment being unable to turn smoothly. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: how to solve the problem of reduced load-bearing capacity of the vehicle loading plate and positioning error in the lateral movement of the vehicle loading plate.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A parking device for a four-way transversely movable vehicle loading plate comprises a vehicle loading frame and a vehicle loading plate located above the vehicle loading frame and capable of transversely moving in four directions therefrom, wherein the vehicle loading frame is provided with transversely and longitudinally arranged side guide rail assemblies, and the side guide rail assemblies are provided with guide wheel slots;

[0008] The bottom of the vehicle loading plate is provided with side guide wheels;

[0009] A steering drive assembly is provided in the vehicle carrier frame, and a plurality of side guide rail steering assemblies corresponding to the positions of the guide wheel slots are provided on the steering drive assembly. The steering drive assembly drives the plurality of side guide rail steering assemblies to rotate synchronously, and alternately overlaps with the guide wheel slots on the transverse and longitudinal side guide rail assemblies. During rotation, the positioning deviation between the side guide rail steering assembly and the side guide wheel can be forcibly corrected.

[0010] As a further solution of the present invention: the steering drive assembly includes a basic frame, a driving member and a side guide rail steering assembly installed at the four corners of the basic frame through a movable connecting rod. Two groups of driven roller assemblies and two groups of traveling roller assemblies are also installed at the four corner positions of the basic frame. The driving member can drive the two groups of driven roller assemblies, the two groups of traveling roller assemblies and the four side guide rail steering assemblies to rotate simultaneously.

[0011] As a further solution of the present invention: the driving part includes a chain transmission assembly and a steering motor group, the chain transmission assembly includes a rotating driving sprocket connected to the driven roller assembly and the traveling roller assembly respectively, and the steering motor group can drive the rotating driving sprocket to rotate through the chain.

[0012] As a further solution of the present invention: angle sprockets are provided on both sides of each of the rotary drive sprockets, wherein the angle sprockets are meshed and connected with the chain from the outside.

[0013] As a further solution of the present invention: the walking roller assembly includes a rotating shaft 2 connected to the corresponding rotating drive sprocket, the upper part of the rotating shaft 2 is connected to the supporting wheel 2 that can contact the carrier frame, and one side of the supporting wheel 2 is provided with a walking motor that can drive it to rotate.

[0014] As a further solution of the present invention: the driven roller assembly includes a rotating shaft 1 connected to the corresponding rotating drive sprocket, and the upper part of the rotating shaft 1 is connected to a roller 1 that can contact the carrier frame.

[0015] As a further solution of the present invention: each of the rotating drive sprockets is connected to the side guide rail steering assembly through a movable connecting rod.

[0016] As a further solution of the present invention: the positioning deviation is ≦30 mm.

[0017] The present invention also discloses a parking system, including a vehicle lifting frame and a plurality of parking mechanisms. The vehicle lifting frame can move a vehicle to a designated parking mechanism layer. A set of vehicle carriers and vehicle loading plates are also provided on the vehicle lifting frame.

[0018] The parking mechanism on each layer includes the above-mentioned vehicle loading frame and the vehicle loading plate. The vehicle loading frames on each layer are arranged in a rectangular array with several groups. The number of vehicle loading plates is one group less than the number of vehicle loading frames. The vehicle loading plates can be moved horizontally or vertically to the designated vehicle loading frames.

[0019] The present invention also discloses a parking method for a parking device, comprising the following steps:

[0020] In the initial state, the vehicle moves onto the vehicle loading plate, which is located at the center of the vehicle loading frame. All the supporting wheel assemblies and the side guide rail steering assemblies in the vehicle loading frame are in a transverse position, and the side guide wheels of the vehicle loading plate are accommodated in the transverse guide channel formed by the side guide rail steering assemblies and the side guide rail assemblies. The steering drive assembly of the vehicle loading frame is activated, pushing the vehicle loading plate to move transversely and drive towards another adjacent vehicle loading frame.

[0021] When the vehicle carrier plate moves horizontally to the center position of the adjacent vehicle carrier frame and stops, the steering drive assembly of the adjacent vehicle carrier frame starts the rotation action, switching all the supporting wheel assemblies and side guide rail steering assemblies of the vehicle carrier frame to the longitudinal position state, and forcibly correcting the possible positioning deviation of the side guide wheels here, and the side guide wheels of the vehicle carrier plate are accommodated in the longitudinal guide channel formed by the side guide rail steering assembly and the side guide rail assembly; the steering drive assembly of the vehicle carrier frame starts, pushing the vehicle carrier plate to move longitudinally, heading towards another adjacent vehicle carrier frame, until it moves to the designated vehicle carrier frame.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention provides a steering drive assembly with switchable direction and a side guide rail steering assembly on the vehicle carrier frame. The steering drive assembly can drive the vehicle carrier plate to move horizontally or vertically above the vehicle carrier frame, and at the same time, the side guide wheel direction and the side guide direction of the vehicle carrier plate are switched in conjunction. Only a single drive motor is required to achieve the above actions, and the various actions are mechanically synchronized, with consistent rotation angles and reliable rigidity.

[0024] 2. When the vehicle carrier plate of the present invention is moved and positioned to the center of the steering drive assembly, when the movement direction of the vehicle carrier plate is switched, the side guide surface of the side guide rail steering assembly rotates tangentially around the side guide wheel of the vehicle carrier plate; if there is a large positioning error between the vehicle carrier plate and the vehicle carrier frame, the side guide surface of the side guide rail steering assembly squeezes the side guide wheel around the rotation center to forcibly correct its position until the vehicle carrier plate coincides with the center of the steering drive assembly and the angle is consistent; the obvious beneficial effect is that each time the vehicle carrier plate turns, the steering mechanism can forcibly correct the position of the vehicle carrier plate, eliminating the original positioning error, and adding mechanical hard synchronization to the traditional sensor positioning for correction, thereby achieving accuracy in the movement of the vehicle carrier plate; the control requirements for the positioning accuracy of the vehicle carrier plate become lower; when installing an array of multiple parking devices, the requirements for the straightness and parallelism of multiple series guide rails are greatly reduced, which is conducive to rapid construction.

[0025] 3. The core component of the parking device of the present invention is the steering drive assembly, which integrates multiple action mechanisms such as vehicle loading plate bearing, lateral or longitudinal movement drive, lateral or longitudinal movement drive direction switching, lateral or longitudinal movement side guide direction switching, etc. The beneficial effect brought by this is that the equipment has a high degree of modularity, which is convenient for rapid array installation to form a large flat garage; and the core functions are concentrated, and the assembly can be completed in the factory, which is convenient for installation and commissioning on the subsequent project site, and has great promotion value.

[0026] 4. During the switching process of the lateral movement direction of the vehicle loading plate of the present invention, the vehicle loading plate can carry loads without any lifting action, so that the parking device can accommodate vehicles with a higher weight and the energy consumption during transportation is low; only side guide wheels need to be provided on the bottom surface of the vehicle loading plate, without any other complex mechanisms; the vehicle loading plate has a simple structure, strong load-bearing capacity, is easy to manufacture and has a very low cost.

[0027] 5. The steering drive assembly and the side guide rail steering assembly of the present invention are both arranged on the vehicle carrier frame, and no power device for steering and driving is provided on the vehicle carrier plate to prevent affecting the load-bearing weight of the vehicle carrier plate; the present invention has high overall performance, greatly reduces the cost compared with traditional technologies, and has high market promotion value.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0055] Example 1

[0056] Reference Figure 1 and Figure 3 A parking device with a four-way transversely movable vehicle loading plate includes a vehicle loading frame 1 and a vehicle loading plate 2 installed above the vehicle loading frame 1 and capable of transversely moving in four directions from the vehicle loading frame 1 to the front, back, left and right, with a car loaded on top of the vehicle loading plate 2.

[0057] For ease of understanding and description, Figure 1 The head of the vehicle is the front end, the rear end is the rear end, and the other directions are based on this as a reference. It should be understood that this direction setting is only for the convenience of description and understanding, and cannot be understood as a limitation of the present invention.

[0058] Reference Figure 2The loading plate 2 is arranged on the upper part of the loading frame 1 and is supported by the supporting wheel assembly inside the loading frame 1. It can be driven by the traveling supporting wheel assembly to achieve lateral and longitudinal translation; four groups of fixed side guide wheels 21 are arranged on the back of the loading plate, which cooperate with the side guide surface of the side guide rail steering assembly 121 in the loading frame 1 to achieve walking guidance.

[0059] Reference Figure 3 The vehicle carrier 1 includes a bottom supporting steel structure 11, and a steering drive assembly 12, a transition wheel assembly 13 and a side guide rail assembly 14 installed on the supporting steel structure 11; the supporting steel structure 11 is set on the ground of the garage parking area, the bottom is connected to the ground, and the upper part is constructed to form a three-dimensional space for parking vehicles; the steering drive assembly 12 is nested inside the supporting steel structure 11 and connected to the supporting steel structure 11.

[0060] Furthermore, the transition wheel assemblies 13 are arranged at the edges of the four sides of the upper surface of the supporting steel structure, and two groups are symmetrically arranged on each side. When the loading plate 2 leaves the edge of the supporting steel structure 11, the loading plate 2 is temporarily supported by the corresponding transition wheel assembly 13.

[0061] Furthermore, the side guide rail assembly 14 includes two transverse guide rails 142 and two longitudinal guide rails 141. Side guide surfaces are provided on the inner sides of the two transverse guide rails 142 and the two longitudinal guide rails 141 and are disposed on the upper portion of the supporting steel structure 11. The steering drive assembly 12 is located within the intermediate drive region formed by the two transverse guide rails 142 and the two longitudinal guide rails 141. The two transverse guide rails 142 and the two longitudinal guide rails 141 extend transversely and longitudinally to the edge of the supporting steel structure 11. As the steering drive assembly 12 drives the side guide rail steering assembly 121 to rotate, the side guide surfaces of the side guide rail steering assembly 121 and the transverse guide rails 142 and the longitudinal guide rails 141 may alternately overlap in the transverse or longitudinal directions. It should be noted that the two sets of transition wheel assemblies 13 located on the longitudinal sides of the supporting steel structure 11 are located between the two longitudinal guide rails 141. Similarly, the two sets of transition wheel assemblies 13 located on the transverse sides of the supporting steel structure 11 are located between the two transverse guide rails 142.

[0062] Further, refer to Figure 11 Two sets of transverse guide rail slots 1421 are symmetrically formed on the two transverse guide rails 142, and two longitudinal guide rail slots 1411 are symmetrically formed on the two longitudinal guide rails 141. The transverse guide rail slots 1421 and the longitudinal guide rail slots 1411 form a cross-shaped design. The transverse guide rail slots 1421 and the longitudinal guide rail slots 1411 have the same size and are used to carry the side guide rail steering assembly 121;

[0063] When the side guide rail steering assembly 121 rotates to the lateral position, the four side guide rail steering assemblies 121 coincide with the two lateral guide rail slots 1421 on the two lateral guide rails 142, so that the two lateral guide rails 142 form a relatively complete lateral guide rail for lateral movement of the side guide wheels 21 below the vehicle loading plate 2;

[0064] When the side guide rail steering assembly 121 rotates to the longitudinal position, the four side guide rail steering assemblies 121 coincide with the two longitudinal guide rail slots 1411 on the two longitudinal guide rails 141, so that the two longitudinal guide rails 141 form a relatively complete transverse guide rail for the longitudinal movement of the side guide wheels 21 below the vehicle loading plate 2.

[0065] Reference Figure 4 and Figure 5 The steering drive assembly 12 includes a base frame 124, and a side guide steering assembly 121, a chain drive assembly 122, a steering motor assembly 123, a traveling roller assembly 125, and a driven roller assembly 126, which are arranged above the base frame 124. There are two sets of traveling roller assemblies 125 and two sets of driven roller assemblies 126, which are arranged in a rectangular shape and cross-arranged at the upper four corners of the base frame 124. Both can rotate around their vertical axes; that is, the two sets of traveling roller assemblies 125 are arranged diagonally opposite each other, and the two sets of driven roller assemblies 126 are also arranged diagonally opposite each other.

[0066] Furthermore, the steering motor group 123 is arranged in the middle of the basic frame 124, and all the walking roller assemblies 125 and the driven roller assemblies 126 are connected in series through the chain transmission assembly 122, and all the walking roller assemblies 125 and the driven roller assemblies 126 are driven by the steering motor group 123 and the chain transmission assembly 122 to rotate along their rotation axes.

[0067] Reference Figure 3 and Figure 4 The basic frame 124 is designed as a rectangular frame, and its two ends are fixed on the middle support rod of the supporting steel structure 11; and the transverse guide rail and the longitudinal guide rail are located above the basic frame 124, and the basic frame will not affect the lateral movement of the vehicle loading plate 2.

[0068] Reference Figure 6 、 Figure 7 、 Figure 8 and Figure 9 The chain transmission assembly 122 includes a chain 1221, a rotating drive sprocket 1222, an angle sprocket 1223, and a tensioning rod 1224. The rotating drive sprocket 1222 is provided with four groups, which are respectively connected to two groups of driven roller assemblies 126 and two groups of walking roller assemblies 125. The steering motor group 123 can drive the rotating drive sprocket 1222 to rotate through the chain 1221.

[0069] Furthermore, each rotating drive sprocket 1222 is provided with an angle sprocket 1223 on both sides, wherein the angle sprocket 1223 is meshed and connected with the chain 1221 from the outside; each rotating drive sprocket 1222 is connected to the side guide rail steering assembly 121 through a movable connecting rod;

[0070] Furthermore, the travel roller assembly 125 includes a second rotating shaft 1253 connected to the corresponding rotating drive sprocket 1222. The upper portion of the second rotating shaft 1253 is connected to a second supporting wheel 1252 capable of contacting the vehicle carrier 1. The second supporting wheel 1252 can rotate freely around a horizontal axis. A travel motor 1254 capable of driving the rotation of the second supporting wheel 1252 is provided on one side.

[0071] Furthermore, the driven roller assembly 126 includes a rotating shaft 1263 connected to the corresponding rotating drive sprocket 1222, and the upper part of the rotating shaft 1263 is connected to a roller 1262 that can contact the carrier frame 1, and the roller 1262 can rotate freely around the horizontal axis.

[0072] Reference Figure 6 、 Figure 13 and Figure 14 The top side of the side guide rail steering assembly 121 is provided with a side guide surface, which is arranged on the outside of each roller assembly on the base frame 124. The side guide rail steering assembly 121 is connected to the rotation drive sprocket 1222 at the bottom of the driven roller assembly 126 via a movable connecting rod 1261, that is, when the driven roller assembly 126 rotates, it can drive the corresponding side guide rail steering assembly 121 to rotate; the side guide rail steering assembly 121 is connected to the rotation drive sprocket 1222 at the bottom of the traveling roller assembly via a movable connecting rod 2 1251, that is, when the traveling roller assembly rotates, it can drive the corresponding side guide rail steering assembly 121 to rotate, and both can rotate around the vertical axis;

[0073] It should be noted that the steering motor assembly 123 drives the driven roller assembly 126 and the traveling roller assembly 125 to rotate around their vertical axes through the chain transmission assembly, which can realize the synchronous rotation of all the roller assemblies within the range of 0 to 90 degrees, that is, the roller assembly has a horizontal (such as Figure 14 as shown) and longitudinally (as Figure 13 Two angular direction states as shown).

[0074] When the driven roller assembly 126 and the traveling roller assembly 125 rotate, the movable link 1 1261 and the movable link 2 1251 synchronously drive the corresponding side guide rail steering assembly 121 to rotate within the range of 0 to 90 degrees, so that the side guide rail steering assembly 121 rotates in the horizontal direction (such as Figure 14 as shown) and longitudinally (as Figure 13 The switching between two angular directions (as shown), and the directions of the driven roller assembly 126 and the traveling roller assembly 125 are always parallel to the direction of the side guide rail steering assembly 121.

[0075] When the carrier plate 2 moves to the center of the steering drive assembly 12, the center of the carrier plate side guide wheel 21 coincides with the rotation center of the side guide rail steering assembly 121. A positioning sensor can be installed at this location to monitor the position of the carrier plate 2 as it enters. When the driven roller assembly 126 and the traveling roller assembly 125 switch between the transverse and longitudinal directions, the chain drive assembly 122 can drive the side guide surface of the side guide rail steering assembly 121 to synchronously switch between the transverse and longitudinal directions around the side guide wheel 21.

[0076] If the vehicle loading plate 2 does not move to the center of the steering drive assembly 12, the center of the vehicle loading plate side guide wheel 21 does not coincide with the rotation center of the side guide rail steering assembly 121. If there is a positioning deviation of ≤30mm between the two (such as Figure 15 and Figure 18 ), when the driven roller assembly 126 and the traveling roller assembly 125 switch from the transverse direction to the longitudinal direction, the chain transmission assembly 122 can drive the side guide surfaces of all the side guide rail steering assemblies 121 to rotate around the side guide wheel 21 (the rotation direction of the four side guide rail steering assemblies 121 is as follows Figure 16 As shown, the side guide wheel 21 is subjected to force as shown in FIG. Figure 19 As shown), during this process, the side guide rail steering assembly 121 squeezes the side guide wheel 21 to rotate, Figure 16 The side guide rail steering assembly 121 on the right side squeezes the side guide wheel 21 and moves to the left. At this time, the positioning deviation can be gradually reduced until the side guide rail steering assembly 121, the driven roller assembly 126 and the walking roller assembly 125 are all rotated to the longitudinal direction. Figure 17 As shown, at this time, the positioning deviation is completely eliminated, and the four carrier plate side guide wheels 21 are located between the two longitudinal guide rails, so that subsequent longitudinal movement can be achieved; accordingly, if there is a positioning deviation when moving longitudinally to the next carrier frame, forced correction can also be performed during the lateral and longitudinal adjustments;

[0077] This application adds mechanical hard synchronization for forced correction on the basis of positioning of the positioning sensor electrical components. Positioning deviations of ≤30mm can be corrected mechanically. This application does not rely entirely on electronic components. When electronic components are inaccurate, mechanical forced correction can also be used to further improve the accuracy of the process of moving the carrier plate to the carrier frame, which is more conducive to promotion.

[0078] The specific operating principles of this application are as follows:

[0079] In the initial state, the vehicle moves onto the vehicle loading plate 2, which is located at the center of the vehicle loading frame 1. All the supporting wheel assemblies and the side guide rail steering assembly 121 in the vehicle loading frame 1 are in a transverse position. The side guide wheels 21 of the vehicle loading plate 2 are accommodated in the transverse guide channel formed by the side guide rail steering assembly 121 and the side guide rail assembly 14. The steering drive assembly of the vehicle loading frame 1 is activated, pushing the vehicle loading plate 2 to move transversely and drive towards another adjacent vehicle loading frame 1.

[0080] When the carrier plate 2 moves horizontally to the center position of the adjacent carrier frame 1 and stops, the steering drive assembly of the adjacent carrier frame 1 starts the rotation action, switching all the roller assemblies and side guide steering assembly 121 of the carrier frame 1 to the longitudinal position state, and forcibly correcting the possible positioning deviation of the side guide wheel 21 here, and the side guide wheel 21 of the carrier plate 2 is accommodated in the longitudinal guide channel formed by the side guide steering assembly 121 and the side guide assembly 14; the steering drive assembly of the carrier frame 1 is started, pushing the carrier plate 2 to move longitudinally, heading towards another adjacent carrier frame 1, until it moves to the designated carrier frame 1.

[0081] Example 2

[0082] Reference Figure 1 The present embodiment discloses a parking system, including a vehicle lifting frame and several layers of parking mechanisms. The vehicle lifting frame can move the car to the parking mechanism on the designated layer. A set of vehicle carriers 1 and vehicle carrier plates 2 are also provided on the vehicle lifting frame. Each layer of the parking mechanism includes a vehicle carrier 1 and a vehicle carrier plate 2. The vehicle carriers 1 on each layer are arranged in a rectangular array with several groups. The number of vehicle carrier plates 2 is one group less than the number of vehicle carriers 1. The car is first parked on the vehicle carrier plate 2 on the vehicle lifting frame, and then moved to the designated layer by the vehicle lifting frame. The vehicle carrier plate 2 can then be moved horizontally or vertically to the designated vehicle carrier 1.

[0083] A plurality of vehicle carriers 1 are arranged in series along a transverse and longitudinal array in a horizontal plane, so that the vehicle carrier plate 2 can be continuously translated in a transverse / longitudinal two-dimensional manner above the vehicle carriers 1 .

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
