Description

Technical Field

[0001] This utility model relates to the field of AGV robot technology, specifically to an AGV charging mechanism and a car transporter. Background Technology

[0002] AGVs are car handling robots that use advanced navigation technology and intelligent control systems to automatically store and retrieve vehicles. AGVs can be used to transport vehicles from entrances or elevators to parking spaces.

[0003] Chinese patent document CN105128686A discloses an automatic charging device and charging method for a fully automated unmanned automated navigation vehicle in an automated container terminal. The ground charging mechanism includes: a ground charging controller, a power board that can be folded down and erected, and a charging plug on the AGV. When the power board is not working, it is folded down and placed below the ground, with a safety cover covering it. When the power board needs to be working, the AGV drives into the charging area, and the ground wireless module transmits a signal to the ground charging controller, which controls the motor to drive the power board to stand up and simultaneously lift the safety cover. The charging plug on the AGV connects to the conductive groove on the power board, and charging begins.

[0004] However, in the above scheme, the ground charging mechanism needs to use a motor structure to pop up the power board during charging so that its conductive groove can be connected to the charging plug on the AGV. The accuracy of the connection is required, and the power board needs to be repeatedly popped up and put down. This can easily lead to an increased failure rate of the charging mechanism, a reduced service life of the charging mechanism, and problems such as poor contact leading to charging failure. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the charging mechanism in the prior art needs to repeatedly pop up and put down the power board during charging, which easily leads to an increased failure rate and reduced service life of the charging mechanism, thereby providing an AGV charging mechanism and a car transporter.

[0006] To solve the above-mentioned technical problems, this utility model provides a charging mechanism, including: a ground device and a vehicle-mounted device. The ground device includes a brush block installed on the ground. The vehicle-mounted device includes a brush plate and a lifting mechanism. The brush plate is movably mounted on the AGV body via the lifting mechanism. The lifting mechanism drives the brush plate to move closer to or away from the brush block. When the brush plate moves closer to the brush block, the brush plate and the brush block cooperate for charging. When the brush plate moves away from the brush block, the brush plate and the brush block disconnect from charging.

[0007] In use, the brush block is fixedly installed at a designated position in the ground charging area. When charging is required, the AGV vehicle arrives at the charging area, and the lifting mechanism drives the brush plate to move closer to the brush block. The brush plate and brush block cooperate to charge automatically. After charging is complete, the lifting mechanism drives the brush plate to move away from the brush block, stopping charging. By setting the lifting device on the AGV vehicle, the brush block installed on the ground does not need to repeatedly bounce up and down. This simplifies the installation structure of the ground charging area, avoids repeated wear and tear on the ground device, reduces the occurrence of ground device failures, and extends its service life. Moreover, the brush plate only needs to be pressed directly down onto the brush block on the ground under the drive of the lifting mechanism. The brush plate uses a flat surface to cooperate with the brush block for charging, resulting in a large contact area and reducing the difficulty of circuit connection. The AGV charging mechanism provided by this utility model solves the problem in the prior art where the charging mechanism needs to repeatedly bounce up and down the power board during charging, which easily leads to an increased failure rate and reduced service life of the charging mechanism.

[0008] Optionally, the brush block is embedded in a groove in the ground, with its upper surface flush with the ground. During AGV charging, the brush plate contacts and engages with the upper surface of the brush block for charging. Alternatively, the brush block is buried in the ground, with its upper surface hidden below the ground surface. During AGV charging, the brush plate engages with the brush block for contactless charging. With these configurations, the upper surface of the brush block is either flush with the ground or hidden below the ground, which does not affect the movement of the AGV, saves ground space, eliminates the need for a separate charging area, and reduces the need for auxiliary mechanisms such as motors to raise and lower the brush block, thus reducing the failure rate.

[0009] Optionally, the lifting mechanism includes: a mounting base, a drive unit, and a scissor extension assembly; the mounting base is mounted on the AGV body; the drive unit is mounted on the mounting base; the scissor extension assembly is mounted on the mounting base, the brush plate is mounted on the first end of the scissor extension assembly, and the second end of the scissor extension assembly is connected to the drive end of the drive unit. The drive unit drives the scissor extension assembly to extend, thereby causing the brush plate to approach the brush block and cooperate with the brush block for charging; alternatively, the drive unit drives the scissor extension assembly to retract, thereby causing the brush plate to move away from the brush block. With the above configuration, the drive unit and the scissor extension assembly are mounted on the AGV body via the mounting base. The drive unit drives the scissor extension assembly to extend or retract, thereby causing the brush plate at the second end of the scissor extension assembly to approach or move away from the brush block, achieving automatic connection and disconnection between the brush block and the brush plate. The scissor extension assembly has a larger extension ratio, effectively controlling the contact and conduction between the brush plate and the brush block, and reducing space occupation while ensuring the extension distance.

[0010] Optionally, a mounting plate is provided at the second end of the scissor lift assembly, and the brush plate is fixedly mounted on the mounting plate. The scissor lift assembly includes a first connecting rod and a second connecting rod, which intersect and are hinged together by a pivot. The first end of the first connecting rod is hinged to the mounting base, and the second end of the first connecting rod is slidably connected to the mounting plate. The first end of the second connecting rod is slidably connected to the mounting base, and the second end of the second connecting rod is hinged to the mounting plate. The second end of the second connecting rod is connected to the drive end of the drive device. With the above configuration, the mounting plate provides an installation position for the brush plate, allowing the brush plate to connect to the scissor lift assembly. The drive end of the drive device drives the first end of the second connecting rod to slide on the mounting base, changing the angle between the first and second connecting rods, causing the second end of the first connecting rod to slide on the mounting plate. By opening and closing the angle between the first and second connecting rods, the scissor lift assembly can be extended or retracted, thereby allowing the brush plate to move closer to or further away from the brush block.

[0011] Optionally, the mounting plate is provided with a limiting plate, the limiting plate having a first limiting groove, and the second end of the first connecting rod having a first limiting part. The first limiting part is slidably disposed within the first limiting groove, and the second end of the second connecting rod is hingedly connected to the limiting plate. With this configuration, the first limiting part slides along the first limiting groove on the limiting plate, thus limiting and guiding the movement of the second end of the first connecting rod.

[0012] Optionally, the mounting plate is provided with two parallel and spaced-apart limiting plates, and a reinforcing plate is provided between the two limiting plates; the scissor extension assembly includes two sets of hinge rod assemblies, each set of hinge rod assemblies including a first connecting rod and a second connecting rod, and the two sets of hinge rod assemblies are respectively installed on the two limiting plates. Through the above arrangement, the reinforcing plate connects the limiting plates on both sides to form an I-shaped structure, and the two sets of first connecting rods and second connecting rods of the scissor extension assembly are respectively installed on the limiting plates on both sides, which can enhance the structural stability and ensure that the brush plate is evenly stressed on both sides under the action of the lifting mechanism, forming a stable charging cooperation with the brush block.

[0013] Optionally, the mounting base includes: a housing and a fixing plate; the housing is fixedly connected to the AGV body, and the bottom of the housing is provided with an opening; the fixing plate is disposed on the housing, the first part of the fixing plate located inside the housing is used to install the scissor lift assembly, the second part of the fixing plate located outside the housing is used to install the drive device, and the side plate of the housing is provided with a clearance groove, through which the drive end of the drive device passes and connects to the scissor lift assembly. With the above configuration, the scissor extension assembly is installed inside the housing via the first part of the fixing plate. When charging is required, the drive end of the drive device drives the first end of the second connecting rod to slide towards the first connecting rod through the clearance groove on the side plate of the housing. The scissor extension assembly extends, causing the brush plate to move from the opening at the bottom of the housing towards the brush plate, thus enabling the brush plate and brush block to cooperate for charging. When charging is complete, the drive end of the drive device drives the first end of the second connecting rod to slide away from the first connecting rod. The scissor extension assembly retracts, causing the brush plate to move away from the brush block and be stored in the opening at the bottom of the housing, thus protecting the brush plate during operation. The drive device is located outside the housing via the second part of the fixing plate, which reduces the size of the housing.

[0014] Optionally, the fixed plate has folded edges on both sides, and the folded edges have second limiting grooves. The scissor extension assembly includes a first connecting rod and a second connecting rod, which intersect and are hinged together by a pivot. The first end of the first connecting rod is hinged to the folded edge, and the second end of the first connecting rod is slidably connected to the mounting plate. The brush plate is fixedly mounted on the mounting plate. The first end of the first connecting rod is hinged to the folded edge, and the first end of the second connecting rod has a second limiting part, which is slidably disposed in the second limiting groove. The driving end of the driving device is rotatably connected to the second limiting part. With the above configuration, the driving end of the driving device pushes the second limiting part to slide along the second limiting groove on the folded edge of the fixed plate, which can limit and guide the movement of the first end of the second connecting rod. The angle between the first connecting rod and the second connecting rod changes, causing the second end of the first connecting rod to slide on the mounting plate. By opening and closing the angle between the first connecting rod and the second connecting rod, the scissor extension assembly can be extended or retracted, thereby allowing the brush plate and the brush block to move closer or further apart.

[0015] Optionally, the first part of the fixing plate is fixedly connected to the top plate of the outer casing, and a positioning groove is provided on the side plate of the outer casing, with the folded edge of the fixing plate embedded in the positioning groove. Through this arrangement, the folded edge of the fixing plate is embedded in the positioning groove to position the fixing plate, and simultaneously, it can cooperate with the fixedly connected first part of the fixing plate to ensure the stability of the fixing plate.

[0016] This utility model provides a car transporter, including an AGV body and an AGV charging mechanism as described in any of the above-mentioned solutions. The AGV body has mounting holes, and the mounting base of the AGV charging mechanism is disposed at the mounting holes. The outer shell of the mounting base is circumferentially provided with a flange that is fixedly connected to the AGV body. When the lifting mechanism of the AGV charging mechanism drives the brush plate of the AGV charging mechanism away from the brush block, it drives the brush plate to move until the bottom of the brush plate is flush with the bottom of the AGV body. With the above configuration, the AGV charging mechanism installs the vehicle-mounted device on the AGV body through the outer shell of the mounting base. When charging is complete, the lifting mechanism drives the brush plate away from the brush block, driving the brush plate to move until the bottom of the brush plate is flush with the bottom of the AGV body.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] This embodiment provides a structure for a charging mechanism that enables automatic charging, used for automatic charging of AGV vehicles.

[0025] like Figure 1Figure 2 shows a specific implementation of a charging mechanism provided in this embodiment, including: a ground device and a vehicle-mounted device. The ground device includes a brush block 2, which is installed on the ground 1. The vehicle-mounted device includes a brush plate 4 and a lifting mechanism. The brush plate 4 is movably mounted on the AGV body 3 via the lifting mechanism. The lifting mechanism drives the brush plate 4 to move closer to or away from the brush block 2. When the brush plate 4 moves closer to the brush block 2, the brush plate 4 cooperates with the brush block 2 for charging. When the brush plate 4 moves away from the brush block 2, the brush plate 4 disconnects from the brush block 2 for charging.

[0026] In use, the brush block 2 is installed at a designated position in the charging area of ​​the ground 1. When charging is required, the AGV body 3 arrives at the charging area, and the lifting mechanism drives the brush plate 4 to move towards the brush block 2. The brush plate 4 and the brush block 2 cooperate to charge, achieving automatic charging. When charging is complete, the lifting mechanism drives the brush plate 4 to move away from the brush block 2, stopping charging. By setting the lifting mechanism on the AGV body 3, the brush block 2 installed on the ground 1 does not need to repeatedly bounce up and down, which not only simplifies the installation structure of the charging area of ​​the ground 1, but also avoids repeated wear and tear on the ground device, reduces the occurrence of ground device failures, and extends its service life. The AGV charging mechanism provided in this embodiment solves the problem in the prior art where the charging mechanism needs to repeatedly bounce up and down the power board during charging, which easily leads to an increased failure rate and reduced service life of the charging mechanism.

[0027] Moreover, in the AGV charging mechanism provided in this embodiment, the brush plate 4 only needs to be pressed directly down on the brush block 2 on the ground 1 under the drive of the lifting mechanism. The brush plate 4 uses a flat surface to cooperate with the brush block 2 for charging, resulting in a large contact area and reducing the difficulty of circuit connection. The AGV charging mechanism provided in this embodiment solves the problem of high accuracy requirements for charging mechanism docking in the prior art and solves the problem of poor contact leading to charging failure.

[0028] As shown in Figures 1 and 2, in the AGV charging mechanism provided in this embodiment, the brush block 2 is embedded in a groove in the ground 1, with its upper surface flush with the ground 1. The brush plate 4 contacts and engages with the upper surface of the brush block 2 for charging. Alternatively, the brush block 2 is buried in the ground 1, with its upper surface hidden below the ground 1, and the brush plate 4 engages with the brush block 2 for contactless charging. The fact that the upper surface of the brush block 2 is flush with or hidden below the ground 1 does not affect the movement of the AGV body 3, saves space on the ground 1, eliminates the need for a separate charging area, and eliminates the need for auxiliary mechanisms such as motors on the ground 1 to raise or lower the brush block 2, thus reducing the failure rate.

[0029] like Figure 1-5 As shown, in the AGV charging mechanism provided in this embodiment, the lifting mechanism includes: a mounting base 5, a driving device 6, and a scissor extension assembly 7; the mounting base 5 is disposed on the AGV body; the driving device 6 is disposed on the mounting base 5; the scissor extension assembly 7 is disposed on the mounting base 5, the brush plate 4 is disposed at the first end of the scissor extension assembly 7, and the second end of the scissor extension assembly 7 is connected to the driving end of the driving device 6. The driving device 6 drives the scissor extension assembly 7 to extend, so as to drive the brush plate 4 close to the brush block 2 and cooperate with the brush block 2 for charging; or, the driving device 6 drives the scissor extension assembly 7 to retract, so as to move the brush plate 4 away from the brush block 2. The drive unit 6 and the scissor lift assembly 7 are mounted on the AGV body 3 via the mounting base 5. The drive unit 6 drives the scissor lift assembly 7 to extend or retract, thereby causing the brush plate 4 at the second end of the scissor lift assembly 7 to move closer to or further away from the brush block 2, achieving automatic connection and disconnection between the brush block 2 and the brush plate 4. The scissor lift assembly 7 has a larger extension ratio, effectively controlling the contact between the brush plate 4 and the brush block 2, and reducing space occupation while ensuring the extension distance. Alternatively, as an alternative implementation, the lifting mechanism can also be configured as an electric push rod, lead screw drive, or other linear drive mechanism.

[0030] It should be noted that the extension direction of the scissor extension assembly 7 can be forward, backward, downward or sideways, depending on the design.

[0031] Specifically, in one embodiment, the drive device 6 is configured as an electric actuator. In another embodiment, the drive device 6 is configured as an electric cylinder.

[0032] like Figure 3 , Figure 4 , Figure 6 As shown, in the AGV charging mechanism provided in this embodiment, a mounting plate 8 is provided at the second end of the scissor lift assembly 7, and the brush plate 4 is fixedly mounted on the mounting plate 8. The mounting plate 8 provides an installation position for the brush plate 4, allowing the brush plate 4 to connect with the scissor lift assembly 7. Alternatively, as an alternative implementation, the mounting plate 8 can be omitted, and the brush plate 4 can be directly mounted on the second end of the scissor lift assembly 7.

[0033] As shown in Figures 1-5, in the AGV charging mechanism provided in this embodiment, the scissor lift extension assembly 7 includes: a first connecting rod 71 and a second connecting rod 72. The first connecting rod 71 and the second connecting rod 72 intersect and are hinged together by a pivot. The first end of the first connecting rod 71 is hinged to the mounting base 5, and the second end of the first connecting rod 71 is slidably connected to the mounting plate 8. The first end of the second connecting rod 72 is slidably connected to the mounting base 5, and the second end of the second connecting rod 72 is hinged to the mounting plate 8. The second end of the second connecting rod 72 is connected to the driving end of the driving device 6. The driving end of the driving device 6 drives the first end of the second connecting rod 72 to slide on the mounting base 5, changing the angle between the first connecting rod 71 and the second connecting rod 72, causing the second end of the first connecting rod 71 to slide on the mounting plate 8. By opening and closing the angle between the first connecting rod 71 and the second connecting rod 72, the scissor lift extension assembly 7 can be extended or retracted, thereby allowing the brush plate 4 to move closer to or further away from the brush block 2.

[0034] like Figure 3-6 As shown, in the AGV charging mechanism provided in this embodiment, a limiting plate 81 is provided on the mounting plate 8, and a first limiting groove 82 is provided on the limiting plate 81. A first limiting part 711 is provided at the second end of the first connecting rod 71. The first limiting part 711 is slidably disposed in the first limiting groove 82, and the second end of the second connecting rod 72 is hingedly connected to the limiting plate 81. The first limiting part 711 slides along the first limiting groove 82 on the limiting plate 81, playing a limiting and guiding role in the movement of the second end of the first connecting rod 71. Alternatively, as an alternative embodiment, the limiting plate 81 can be omitted, and the first limiting groove 82 is disposed on the mounting plate 8.

[0035] like Figure 5 , Figure 6 As shown, in the AGV charging mechanism provided in this embodiment, the mounting plate 8 is provided with two parallel and spaced-apart limiting plates 81, and a reinforcing plate is provided between the two limiting plates 81; the scissor extension assembly 7 includes two sets of hinge rod assemblies, each set of hinge rod assemblies including a first connecting rod 71 and a second connecting rod 72, and the two sets of hinge rod assemblies are respectively installed on the two limiting plates 81. The reinforcing plate connects the limiting plates 81 on both sides to form an I-shaped structure. The two sets of hinge rod assemblies of the scissor extension assembly 7 are respectively installed on the limiting plates 81 on both sides, which can enhance the structural stability and ensure that the brush plate 4 is subjected to uniform force on both sides under the action of the lifting mechanism, forming a stable charging cooperation with the brush block 2.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, in the AGV charging mechanism provided in this embodiment, the mounting base 5 includes: a housing 51 and a fixing plate 52; the housing 51 is fixedly connected to the AGV body 3, and the bottom of the housing 51 is provided with an opening; the fixing plate 52 is disposed on the housing 51, the first part of the fixing plate 52 located inside the housing 51 is used to install the scissor extension assembly 7, the second part of the fixing plate 52 located outside the housing 51 is used to install the drive device 6, and a clearance groove 511 is provided on the side plate of the housing 51, and the drive end of the drive device 6 passes through the clearance groove 511 and is connected to the second connecting rod 72. The scissor lift assembly 7 is installed inside the housing 51 via the first part of the fixing plate 52. When charging is required, the driving end of the driving device 6 passes through the clearance groove 511 on the side plate of the housing 51 and drives the first end of the second connecting rod 72 to slide towards the first connecting rod 71. The scissor lift assembly 7 extends, causing the brush plate 4 to move from the opening at the bottom of the housing 51 towards the brush block 2, thus enabling the brush plate 4 and the brush block 2 to cooperate for charging. When charging is complete, the driving end of the driving device 6 drives the first end of the second connecting rod 72 to slide away from the first connecting rod 71. The scissor lift assembly 7 retracts, causing the brush plate 4 to move away from the brush block 2 and be stored in the opening at the bottom of the housing 51, thus protecting the brush plate 4 during movement. The driving device 6 is located outside the housing 51 via the second part of the fixing plate 52, which reduces the volume of the housing 51. Alternatively, as an alternative implementation, the first end of the scissor lift assembly 7 is connected to the top plate of the housing 51, and the fixing plate 52 is disposed on the side plate of the housing 51. The fixing plate 52 is only used to install the drive device 6.

[0037] Specifically, the fixing plate 52 is provided with a hollow area for mounting the driving device 6.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7As shown, in the AGV charging mechanism provided in this embodiment, the fixed plate 52 has folded edges on both sides, and the folded edges are provided with second limiting grooves 521; the scissor extension assembly 7 includes: a first connecting rod 71 and a second connecting rod 72, the first connecting rod 71 and the second connecting rod 72 intersect and are hinged together by a pivot, the first end of the first connecting rod 71 is hinged to the folded edge, the second end of the first connecting rod 71 is slidably connected to the mounting plate 8, the brush plate 4 is fixedly mounted on the mounting plate 8, the first end of the first connecting rod 71 is hinged to the folded edge, the first end of the second connecting rod 72 is provided with a second limiting part 721, the second limiting part 721 is slidably mounted in the second limiting groove 521, and the driving end of the driving device 6 is rotatably connected to the second limiting part 721. The driving end of the driving device 6 pushes the second limiting part 721 to slide along the second limiting groove 521 on the folded edge of the fixed plate 52, which can limit and guide the movement of the first end of the second connecting rod 72. The angle between the first connecting rod 71 and the second connecting rod 72 changes, causing the second end of the first connecting rod 71 to slide on the mounting plate 8. By opening and closing the angle between the first connecting rod 71 and the second connecting rod 72, the extension or retraction of the scissor extension assembly 7 is realized, thereby allowing the brush plate 4 to move closer to or further away from the brush block 2. Alternatively, as an alternative embodiment, the folded edge can be omitted, and the second limiting groove 521 is provided on the fixed plate 52.

[0039] like Figure 4 , Figure 8 As shown, in the AGV charging mechanism provided in this embodiment, the first part of the fixing plate 52 is fixedly connected to the top plate of the outer shell 51, and a positioning groove 512 is provided on the side plate of the outer shell 51. The folded edge of the fixing plate 52 is embedded in the positioning groove 512. The folded edge of the fixing plate 52 is embedded in the positioning groove 512 to position the fixing plate 52, and at the same time, it can cooperate with the first part of the fixedly connected fixing plate 52 to ensure the stability of the fixing plate 52.

[0040] How to use: like Figure 1 As shown, in this embodiment, when charging is required, the driving device 6 pushes the second connecting rod 72, the first connecting rod 71 and the second connecting rod 72 open, the scissor extension assembly 7 extends, and the brush plate 4 moves closer to the brush block 2 to achieve automatic charging; when charging is completed, the driving device 6 pulls the second connecting rod 72, the first connecting rod 71 and the second connecting rod 72 close, the scissor extension assembly 7 retracts, and the brush plate 4 moves away from the brush block 2 to stop charging.

[0041] In addition, such as Figure 1 , Figure 2 As shown, this embodiment also provides a car transporter, including an AGV body 3 and the AGV charging mechanism described in the above embodiment. The AGV body 3 has mounting holes, and the mounting base 5 of the AGV charging mechanism is disposed at the mounting holes. The outer shell 51 of the mounting base 5 is circumferentially provided with a flange that is fixedly connected to the AGV body 3. When the lifting mechanism of the AGV charging mechanism drives the brush plate of the AGV charging mechanism away from the brush block 2, it drives the brush plate 4 to move until the bottom of the brush plate 4 is flush with the bottom of the AGV body 3. The AGV charging mechanism installs the vehicle-mounted device on the AGV body 3 through the outer shell 51 of the mounting base 5. After charging is completed, the lifting mechanism drives the brush plate 4 away from the brush block 2, so that the bottom of the brush plate 4 is flush with the bottom of the AGV body 3, realizing automatic charging of the car transporter, enabling the car transporter to operate around the clock and adapt to more scenarios.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
