[0037] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] The present invention provides a vehicle loading plate storage and retrieval system, which is applied to an intelligent garage.

[0039] Reference Figures 1 to 2 In this embodiment, the vehicle loading plate storage and retrieval system includes at least one AGV trolley 100 with a lifting mechanism, at least one vehicle loading plate storage rack and at least one vehicle loading plate 300 matched with the vehicle loading plate storage rack.

[0040] Further integration Figure 3 and Figure 4 The vehicle loading plate storage rack 200 of this embodiment includes a plurality of support sides 20 spaced apart along a first horizontal direction X. Each support side 20 includes a plurality of support frames 21 spaced apart along a second horizontal direction Y, which is perpendicular to the first horizontal direction X. The support frames 21 each have at least one layer of support plates B. The support plates B include front support positions B1 and rear support positions B2 sequentially distributed along the second horizontal direction Y. Both the front support positions B1 and the rear support positions B2 are provided for supporting legs of the vehicle loading plates 300. A storage space is formed between any two adjacent support sides 20 for stacking and storing vehicle loading plates 300. The front support positions B1 of the support plates B on the same layer of the support frames 21 of a support side 20, together with the rear support positions B2 of the support plates B on the same layer of the support frames 21 of an adjacent support side 20, form a receiving position in the storage space for stacking vehicle loading plates 300.

[0041] Reference Figure 3 and Figure 4 The vehicle loading plate storage rack 200 of this embodiment is described in detail by taking as an example a rack having three supporting sides 20, each supporting side 20 including two supporting frames 21, and each supporting frame 21 having four layers of support plates B spaced apart in the vertical direction. In this embodiment, the two front supporting positions B1 of the same layer of support plates B (e.g., the bottom layer of support plates B) of the two supporting frames 21 of one supporting side 20 (e.g., the leftmost supporting side 20 in the figure) of the vehicle loading plate storage rack 200, and the two rear supporting positions B2 of the same layer of support plates B (e.g., the bottom layer of support plates B) of the two supporting frames 21 of the adjacent supporting side 20 (e.g., the middle supporting side 20 in the figure), form a receiving position for stacking vehicle loading plates 300.

[0042] In this embodiment, the distance between the lowest support plate B of the support frame 21 and the bottom end of the support frame 21 is greater than the combined height of the AGV 100 and a loading plate 300, allowing the AGV 100 to carry the loading plate 300 in and out of the storage space of the loading plate storage rack 200. The spacing between two adjacent support sides 20 is greater than the width of the AGV 100 and the width of the loading plate 300, ensuring that the AGV 100 can carry the loading plate 300 in and out of the storage space.

[0043] Reference Figure 1 、 Figure 2 and Figure 6 , wherein the vehicle loading plate 300 of this embodiment includes a load-bearing plate 301 for placing the vehicle and a driving device (not shown in the figure) provided on the load-bearing plate 301, and a supporting assembly is provided at both ends of the load-bearing plate 301, and the supporting assembly includes two movable legs 302, and the two movable legs 302 extend from both sides of the load-bearing plate 301 respectively. The two movable legs 302 of the same supporting assembly are staggered, and the spacing between the two movable legs 302 on one side of the load-bearing plate 301 is equal to the spacing between the two movable legs 302 on the other side; the driving device is connected to each movable leg 302, and is used to drive each movable leg 302 to switch between an extended state and a retracted state; in the extended state, the movable leg 302 extends out of the load-bearing plate 301; in the retracted state, the movable leg 302 is retracted into the load-bearing plate 301.

[0044] Combined with reference Figures 1 to 3 That is, the four movable legs 302 of the loading plate 300 correspond to the two front support positions B1 and the two rear support positions B2 of the same receiving position of the loading plate storage rack 200. When the loading plate 300 is stored in the storage space, the four movable legs 302 of the loading plate 300 are in an extended state, and the two movable legs 302 on one side of the loading plate 301 are respectively placed on the two front support positions B1 of the same receiving position, and the two movable legs 302 on the other side of the loading plate 301 are respectively placed on the two rear support positions B2 of the same receiving position.

[0045] In this embodiment, the front support position B1 and the rear support position B2 of the same support plate B of each support frame 21 are respectively used for placing the movable legs 302 of the vehicle loading plates 300 in the two adjacent storage spaces. Therefore, each of the two adjacent storage spaces shares the support frames 21 of a support side 20, which greatly reduces the use of the support frames 21 of the vehicle loading plate storage rack 200, reduces costs, and reduces occupied space.

[0046] The process of storing the vehicle plate storage rack 200 of this embodiment is as follows: 1. The AGV trolley 100 enters any storage space of the vehicle plate storage rack 200 with the vehicle plate 300 placed thereon. At this time, the movable legs 302 of the vehicle plate 300 on the AGV trolley 100 are in a retracted state; 2. When there is no vehicle plate 300 stored in the storage space entered by the AGV trolley 100, the AGV trolley 100 lifts the vehicle plate 300 thereon to a position where the height exceeds the top support plate B of the support frame 21. Then, the AGV trolley 100 controls the driving device of the vehicle plate 300 to switch the movable legs 302 to the extended state, the lifting mechanism descends and resets, and the movable legs 302 of the vehicle plate 300 are correspondingly placed on the corresponding support positions of the top support plates B of each support frame 21, completing the storage of the vehicle plate 300. 3. When a certain number of vehicle loading plates 300 have been stored in the storage space entered by the AGV trolley 100, the AGV trolley 100 lifts the vehicle loading plates 300 through the lifting mechanism to lift up the vehicle loading plates 300 stored in the storage space together, and the lifting height exceeds the thickness of one vehicle loading plate 300. Then, the AGV trolley 100 controls the driving device of the vehicle loading plate 300 to switch each movable support leg 302 to the extended state, and the lifting mechanism descends and resets. Each movable support leg 302 of the vehicle loading plate 300 is correspondingly placed on the corresponding support position of the corresponding layer support plate B of each support frame 21, completing the storage of the vehicle loading plate 300. Or, 4. When a certain number of carrier plates 300 have been stored in the storage space entered by the AGV trolley 100, the AGV trolley 100 lifts the carrier plate 300 to a position where its height exceeds the highest support plate B in the storage space where no carrier plates 300 are stored, and then the AGV trolley 100 controls the driving device of the carrier plate 300 to switch each movable support leg 302 to an extended state, and the lifting mechanism descends and resets, and each movable support leg 302 of the carrier plate 300 is placed on the corresponding support position of the corresponding layer of support plate B of each support frame 21.

[0047] The process of taking out the vehicle plate 300 from the vehicle plate storage rack 200 of this embodiment is as follows: the AGV trolley 100 enters any storage space of the vehicle plate storage rack 200, and the AGV trolley 100 is lifted by the lifting mechanism to lift one or more vehicle plates 300 above it to a certain height, then, the AGV trolley 100 controls the driving device of the vehicle plate 300 contacted by its lifting mechanism to switch each movable support leg 302 to a retracted state, then, the lifting mechanism descends and resets, and a vehicle plate 300 is taken out and put onto the AGV trolley 100, the AGV trolley 100 withdraws from the storage space and transports the vehicle plate 300 to the desired position, completing the operation of taking out the vehicle plate 300.

[0048] The vehicle loading plate access system of this embodiment has a vehicle loading plate storage rack 200 which adopts a plurality of support sides 20 spaced apart along a first horizontal direction X, and each support side 20 includes a plurality of support racks 21 spaced apart along a second horizontal direction Y, and a storage space is formed between any two adjacent support sides 20; the support rack 21 has at least one layer of support plates B, and the support plates B include front support positions B1 and rear support positions B2 distributed in sequence along the second horizontal direction Y, and each front support position B1 of each support rack 21 of a support side 20 on the same layer of support plates B is aligned with each rear support position B1 of each support rack 21 of an adjacent support side 20 on the same layer of support plates B. Position B2 constitutes a loading position for stacking the vehicle loading plates 300 in the storage space; and the positions of the movable legs 302 of the vehicle loading plates 300 correspond to the two front support positions B1 and the two rear support positions B2 of the same loading position; in this way, the front support position B1 and the rear support position B2 of the same support plate B of each support frame 21 are respectively used to support the movable legs 302 of the vehicle loading plates 300 in the two adjacent storage spaces. Each of the two adjacent storage spaces shares the support frames 21 of the same support side 20, which greatly reduces the use of the support frames 21 of the vehicle loading plate storage rack 200, reduces costs, and reduces the occupied space. Moreover, all the vehicle loading plates 300 in the same storage space are stored in an aligned and stacked manner, ensuring that the centers of the vehicle loading plates 300 in the same storage space are on the same vertical line, making the space occupied by the stored vehicle loading plates 300 more compact and more conducive to the arrangement and scheduling of the vehicle loading plate storage rack 200.

[0049] It should be noted that, in other embodiments, depending on the load-bearing strength of the loading plate 300, for a loading plate 300 that requires a greater load-bearing capacity, one or more support components can be appropriately added between the two ends of the supporting plate 301 of the loading plate 300, and each supporting side 20 of the corresponding storage room of the loading plate 300 adopts a support frame 21 scheme corresponding to the number of support components of the loading plate 300; the two movable legs 302 of each support component added to the supporting plate 301 are still staggered.

[0050] Furthermore, in this embodiment, the support assembly's movable legs 302 are telescopic legs with their extension and retraction directions perpendicular to the sides of the support plate 301. The drive device operates by extending and retracting the telescopic legs to switch between the extended and retracted states. Of course, in other embodiments, the support assembly's movable legs 302 may also employ other designs, such as one end of the movable legs 302 pivotally connected to the support plate 301, with the drive device driving the movable legs 302 to rotate to switch between the extended and retracted states.

[0051] Further, refer to Figure 4 and Figure 5In this embodiment, each layer of support plates B is vertically spaced apart on the support frame 21, and the distance between two adjacent layers of support plates B is greater than the thickness of at least one vehicle carrier 300, so that at least one vehicle carrier 300 can be stored. The distance between two adjacent layers of support plates B is generally set based on the maximum load capacity of the lifting mechanism of the AGV trolley 100. For example, if the maximum load capacity of the lifting mechanism is four vehicle carriers 300, then the distance between two adjacent layers of support plates B is greater than the combined thickness of the four vehicle carriers 300. The number of layers of support plates B on the support frame 21 is set based on the maximum lifting height of the lifting mechanism of the AGV trolley 100, and the height of the highest layer of support plates B must be less than the maximum lifting height of the lifting mechanism. The storage space of the vehicle carrier storage rack 200 of this embodiment is greatly increased by multi-layer storage, thereby improving the storage capacity and space utilization of the vehicle carrier storage rack 200.

[0052] Further, refer to Figure 4 and Figure 5 In this embodiment, the support frame 21 includes two outer columns 211 spaced apart along the second horizontal direction Y. The support plate B is located between the two outer columns 211, and the two ends of the support plate B are respectively fixed to the two outer columns 211. The two outer columns 211 secure the two ends of each support plate B, ensuring the load-bearing capacity of the support plate B.

[0053] Further, refer to Figure 4 and Figure 5 In this embodiment, the support frame 21 also includes a middle column 212 disposed between the two outer columns 211. The middle column 212 is connected to each layer of support plates B. The front support position B1 of the support plate B is located between the middle column 212 and one outer column 211, and the rear support position B2 of the support plate B is located between the middle column 212 and the other outer column 211. The provision of the middle column 212 firstly further enhances the connection firmness of the support plates B and further increases the load-bearing capacity of the support plates B. Secondly, the middle column 212 separates the front support position B1 and the rear support position B2 of the support plate B, preventing the movable legs 302 placed on the front support position B1 and the rear support position B2 of the support plate B from sliding and interfering with each other, thereby ensuring normal loading and unloading operations of the vehicle loading plate 300. In this embodiment, the middle column 212 is disposed so as to penetrate each support plate B, but other arrangements may also be employed.

[0054] Further, refer to Figure 5In this embodiment, buffer blocks 214 are fixed on the front support position B1 and the rear support position B2 respectively, so that the movable support leg 302 does not directly contact the support plate B. In this way, the problems such as noise and damage to the movable support leg 302 or the support plate B due to the rigid collision between the movable support leg 302 and the support plate B during the loading and unloading process of the vehicle loading plate 300 can be avoided. At the same time, the buffer blocks 214 also have an anti-slip function, which can prevent the movable support leg 302 from sliding relative to the support plate B, thereby ensuring the storage stability of the vehicle loading plate 300. In addition, the support frame 21 also includes a fixed base plate 213, and the outer columns 211 and the middle column 212 are fixed on the fixed base plate 213. The fixed base plate 213 is used to be fixed to the ground. The fixed base plate 213 can be fixed by being connected to a screw buried in the ground and locked by a nut, or other fixing methods can be adopted. Furthermore, the two outer columns 211 of this embodiment are connected to the fixed base plate 213 by reinforcing ribs 215.

[0055] In this embodiment, each support plate B can be integrally formed with the two outer columns 211, the two reinforcing ribs 215, the middle column 212 and the fixed base plate 213 of the support frame 21, or can be fixed by welding; of course, other methods can also be used, for example, by locking and fixing with studs.

[0056] The present invention further provides a vehicle loading plate storage rack. The specific structure of the vehicle loading plate storage rack is described with reference to the above embodiments and corresponding drawings, and will not be described in detail here.

[0057] The present invention further provides a vehicle loading plate matched with the vehicle loading plate storage rack of the present invention. The specific structure of the vehicle loading plate is referred to the above embodiment and corresponding drawings, and will not be described in detail here.

[0058] The present invention also proposes a vehicle loading plate storage and access method, which is applied to the above-mentioned vehicle loading plate storage and access system. The specific structure of the vehicle loading plate storage and access system refers to the above-mentioned embodiment, wherein the vehicle loading plate storage and access system of this embodiment also includes a main control system connected to the AGV car for communication.

[0059] like Figure 7 As shown, Figure 7 Schematic diagram of a process of storing and accessing a vehicle loading plate according to an embodiment of the present invention.

[0060] In this embodiment, the vehicle loading plate access method includes:

[0061] Step S101: After receiving a storage request, the main control system determines a first target storage space to be stored;

[0062] The master control system manages and records the number of pallets stored in each storage space of each pallet storage rack, and updates the number of pallets stored in each storage space in real time based on the pallet access schedule. When the master control system receives a storage request, it selects a storage space on a pallet storage rack as the first target storage space to be stored. The master control system determines the first target storage space to be stored by randomly selecting one from each unfilled storage space, selecting the one with the smallest remaining storage capacity from each unfilled storage space, or selecting the unfilled storage space closest to the AGV car (i.e., the AGV car that needs to store the pallet) to be stored. The storage request can be sent to the master control system by the AGV car that needs to store the pallet, or it can be generated by the master control system when it detects that the AGV car needs to store the pallet (for example, after the AGV car delivers the vehicle from the garage to the vehicle pick-up and handover area and the vehicle is taken away), or it can be generated by input from a management personnel, etc.

[0063] Step S102: obtaining the number of vehicle loading plates currently stored in the first target storage space, and determining a first height according to the obtained number of vehicle loading plates.

[0064] After determining the first target storage space, the main control system obtains the number of pallets currently stored in the first target storage space and then determines a first height based on the obtained number of pallets. This first height is the height that the lifting mechanism needs to lift when the AGV to store the pallet is placed in the first target storage space. The main control system stores a first mapping table between the number of pallets stored in the storage space and the lifting height. For example, the mapping relationship between the number of stored vehicle plates in the storage space and the lifting height can be: when the number of stored vehicle plates is 0, the corresponding lifting height is h1; when the number of stored vehicle plates is 1 to n, the corresponding lifting height is h2; when the number of stored vehicle plates is n+1 to 2n, the corresponding lifting height is h3; when the number of stored vehicle plates is 2n+1 to 3n, the corresponding lifting height is h4. The mapping relationship in this example corresponds to the case where the support frame of the vehicle plate storage rack is provided with a 4-layer support plate structure, and the top support plate only stores one vehicle plate, and the other support plates store the same number of vehicle plates, and n represents the number of vehicle plates that can be stored on each layer. After the main control system obtains the number of vehicle plates currently stored in the first target storage space, it can determine the first height by consulting the first mapping table.

[0065] Step S103: Send a first operation signal to the AGV vehicle to be used for storing the vehicle pallet, wherein the first operation signal includes first target storage space information and first height information.

[0066] After determining the first height, the main control system sends a first operation signal to the AGV to store the pallet. The first operation signal includes the first target storage space information and the first height information. The first target storage space information can be the number or location coordinates of the first target storage space, while the first height information is a numerical value or code indicating the lifting height of the AGV's lifting mechanism.

[0067] In step S104, after receiving the first operation signal, the AGV moves to the position of the first target storage space and then controls its lifting mechanism to lift to a first height.

[0068] After the AGV car with the carrier plate to be stored receives the first operating signal sent by the main control system, it extracts the first target storage space information and the first height information in the first operating signal, and moves to the position of the first target storage space according to the first target storage space information, that is, the AGV car enters the first target storage space with the carrier plate, and then controls its lifting mechanism to lift to the first height according to the first height information.

[0069] In step S105 , the AGV sends a first driving signal to the driving device of the vehicle loading plate that its lifting mechanism contacts. The first driving signal is used to enable the driving device to drive each movable leg of the vehicle loading plate to switch to an extended state.

[0070] After the AGV trolley controls its lifting mechanism to lift to the first height, that is, the carrier plate on the AGV trolley is lifted to a height higher than the corresponding layer of support plate of the support frame, the AGV trolley sends a first driving signal to the driving device of the carrier plate it contacts through the lifting mechanism, and the driving device of the carrier plate drives the various movable legs of the carrier plate to switch to the extended state, that is, the various movable legs of the carrier plate are extended.

[0071] Step S106: The AGV controls its lifting mechanism to reset.

[0072] After the movable legs of the vehicle loading plate are extended, the AGV controls its lifting mechanism to reset and descend, and the vehicle loading plate lifted by the lifting mechanism descends and is placed on the support plates of the support frame through the movable legs, thus completing the storage of the vehicle loading plate.

[0073] like Figure 8 As shown, Figure 8 Schematic diagram of the flow of the second embodiment of the vehicle loading plate access method of the present invention.

[0074] In this embodiment, the vehicle loading plate access method further includes:

[0075] Step S201: After receiving the take-out request, the main control system determines a second target storage space to be taken out.

[0076] When the main control system receives a retrieval request, it will select a storage space on a certain vehicle pallet storage rack as the second target storage space to be retrieved. The main control system can determine the second target storage space by randomly selecting one from the various storage spaces storing vehicle pallets, or by selecting the one with the least number of storage spaces storing vehicle pallets, or by selecting the storage space with vehicle pallets closest to the AGV car to be retrieved (i.e., the AGV car that needs to retrieve the vehicle pallet), etc. The retrieval request can be sent to the main control system by the AGV car that retrieves the vehicle pallet, or it can be generated by the main control system based on the detection of the need to retrieve the vehicle pallet, or by input from a management personnel, etc.

[0077] Step S202, obtaining the number of vehicle loading plates currently stored in the second target storage space, and determining a second height according to the obtained number of vehicle loading plates;

[0078] After determining the second target storage space, the main control system obtains the number of pallets currently stored in the second target storage space and then determines a second height based on the obtained number of pallets. This second height is the height that the lifting mechanism needs to lift when the AGV to retrieve a pallet from the second target storage space. The main control system stores a second mapping table between the number of pallets stored in the storage space and the lifting height. For example, the mapping relationship between the number of stored vehicle plates in the storage space and the lifting height can be: when the number of stored vehicle plates is 1, the corresponding lifting height is h1; when the number of stored vehicle plates is 2 to n+1, the corresponding lifting height is h2; when the number of stored vehicle plates is n+2 to 2n+1, the corresponding lifting height is h3; when the number of stored vehicle plates is 2n+2 to 3n+1, the corresponding lifting height is h4. The mapping relationship in this example corresponds to the case where the support frame of the vehicle plate storage rack is provided with a 4-layer support plate structure, and the top support plate only stores one vehicle plate, and the other support plates store the same number of vehicle plates. n represents the number of vehicle plates that can be stored on each layer. After the main control system obtains the number of vehicle plates currently stored in the second target storage space, it can determine the second height by consulting the second mapping table.

[0079] Step S203: Send a second operation signal to the AGV to be used to pick up the vehicle loading board, wherein the second operation signal includes second target storage space information and second height information;

[0080] After determining the second height, the main control system sends a second operating signal to the AGV that is to pick up the pallet. The second operating signal includes the second target storage space information and the second height information. The second target storage space information can be the number or location coordinates of the second target storage space, while the second height information is a numerical value or code indicating the lifting height of the AGV's lifting mechanism.

[0081] Step S204: After receiving the second operation signal, the AGV moves to the second target storage space and controls its lifting mechanism to raise the vehicle to a second height.

[0082] After the AGV car to pick up the loading plate receives the second operating signal sent by the main control system, it extracts the second target storage space information and the second height information in the second operating signal, and moves to the position of the second target storage space according to the second target storage space information, that is, the AGV car enters the second target storage space with the loading plate, and then controls its lifting mechanism to lift to the second height according to the second height information.

[0083] Step S205: The AGV sends a second drive signal to the drive device of the vehicle loading plate that its lifting mechanism contacts. The second drive signal is used to cause the drive device to drive each movable leg of the vehicle loading plate to switch to a retracted state.

[0084] After the AGV trolley to take the loading plate controls its lifting mechanism to rise to the second height, that is, the lifting mechanism of the AGV trolley contacts the loading plate above it, and the various movable legs of the loading plate it contacts are disengaged from the corresponding support plates of the support frame, at this time the AGV trolley sends a second driving signal to the driving device of the loading plate it contacts through the lifting mechanism, and the driving device of the loading plate drives the various movable legs of the loading plate to switch to the retracted state, that is, the various movable legs of the loading plate are retracted to the load-bearing plate.

[0085] Step S206: The AGV controls its lifting mechanism to reset.

[0086] After the carrier plate's legs are retracted, the AGV controls its lifting mechanism to reset and descend, and the carrier plate it touches descends onto the AGV, completing the removal of the carrier plate. The AGV can then transport the carrier plate to a designated location (such as a parking area).

[0087] The vehicle loading plate storage and retrieval system of the present invention realizes automatic storage and retrieval of the vehicle loading plate through the above-mentioned vehicle loading plate storage and retrieval method, and the retrieval and placement operations of the vehicle loading plate are more intelligent and convenient.
