[0035] Example

[0036] Reference Figure 1-Figure 10 , is a composite AGV trolley controller disclosed in the utility model, the utility model includes: a controller, the controller includes a shell, an interface board 20, a base board 30 and an ARM core board 312, the interface board 20, the base board 30 and the ARM core board 312 are inside the shell, the interface board 20 is connected to the upper part of the base board 30, the ARM core board 312 is connected to the lower part of the base board 30, and the ARM core board 312 is abutted against the inner side of the shell; a function signal interface is arranged on the top of the controller, the function signal interface includes five Ethernet interfaces 22, an encoder interface 27, four antenna SMA sockets 32, six indicator lights and two base board main connectors 36; a side debugging interface is arranged on the side of the controller, the side debugging interface includes two USB-C interfaces 38, an audio interface 310 and a USB-C debugging interface 311.

[0037] Specifically, the shell is provided with openings on the top and the side. The top opening is a functional signal interface for unified wiring of the AGV cart, and the side opening is a side debugging interface for AGV debugging wiring. The interface board 20 and the base board 30 adopt an upper and lower stacking architecture, and are respectively provided with plug-in connectors. The internal connector 21 of the interface board is downward, and the internal connector 31 of the base board is upward. The 5G module 314 and the WiFi module 313 are arranged at the bottom of the base board 30, and the antenna is fixed on the shell. The base board 30 is equipped with a connector at the bottom, which is plugged into the ARM core board 312. The ARM core board 312 is equipped with a heat dissipation device, which contacts the metal surface at the bottom of the shell to achieve heat dissipation.

[0038] The overall structure of this controller is more compact and more integrated. The plug-ins at the opening of the shell are equipped with waterproof gaskets, and after assembly, they can reach the IP65 waterproof and dustproof level. This controller has 5G communication and WiFi communication functions. In AGV applications, the main body can support wireless communication required by different scenarios.

[0039] Optionally, the shell includes an upper shell 11 and a lower shell 12; the upper shell 11 is provided with functional signal interface openings, the functional signal interface openings include an Ethernet interface opening 113, an encoder interface opening 114, an antenna opening 115, an indicator light opening 112 and a bottom plate main interface opening 116; the side of the lower shell 12 is provided with a side debugging interface opening 124.

[0040] Specifically, by dividing the outer shell into an upper shell 11 and a lower shell 12, the internal structure of the controller is made more modular, which is convenient for assembly and disassembly, and improves the convenience of maintenance. The functional signal interface openings provided in the upper shell 11 and the side debugging interface openings 124 of the lower shell 12 provide special channels for various interfaces, which not only ensure the stability of the interface, but also effectively prevent dust, moisture and other impurities in the external environment from entering the interior of the controller, thereby improving the service life and reliability of the controller. This design, combined with sealing measures such as waterproof gaskets, can effectively improve the waterproof and dustproof level of the controller, so that it can operate stably in harsh environments, such as outdoor, humid or dusty environments. Reasonable interface layout helps to optimize internal wiring, reduce the possibility of line confusion and mutual interference, and thus improve the overall performance of the controller.

[0041] Optionally, a heat sink is provided at the bottom of the ARM core board 312 , and the heat sink abuts against the metal surface of the lower shell 12 .

[0042] Specifically, the ARM core board 312 will generate a certain amount of heat during operation. If it is not dissipated in time, it may cause its performance to degrade or be damaged. By arranging a heat dissipation device at the bottom and abutting against the metal surface of the lower shell 12, the good thermal conductivity of the metal can be fully utilized to quickly conduct the heat to the shell and then dissipate it into the air. This heat dissipation method is not only efficient, but also low-cost, and does not require complex heat dissipation structures such as additional fans or heat sinks. Good heat dissipation conditions can slow down the aging speed of the internal components of the ARM core board 312, thereby extending its service life. At the same time, the failure rate caused by overheating is reduced, and maintenance costs are also reduced.

[0043] Optionally, the Ethernet interface opening 113 passes through the Ethernet interface 22 , the encoder interface opening 114 passes through the encoder interface 27 , the antenna opening 115 passes through the antenna SMA seat 32 , the baseboard main interface opening 116 passes through the baseboard card main connector 36 , and the indicator light passes through the indicator light opening 112 .

[0044] Optionally, seven internal board fixing studs 122 are provided on the inner side of the lower shell 12 ; reinforcing ribs 123 are provided on both sides of the inner side of the lower shell 12 ; and main controller fixing holes 121 are provided at the four corners of the inner side of the lower shell 12 .

[0045] Specifically, each interface and corresponding opening are precisely designed and manufactured to ensure that the interface can accurately pass through the corresponding opening and accurately connect with external cables or devices. This greatly reduces the possibility of wiring errors and improves work efficiency. This design makes the internal structure of the controller more compact and reduces unnecessary space waste. At the same time, due to the close fit between the interface and the opening, the structure of the controller is more stable and less susceptible to external vibration or impact.

[0046] Optionally, four fixing studs 111 are provided on the inner side of the upper shell 11 ; the fixing studs 111 are fixedly connected to the main controller fixing holes 121 by screws.

[0047] Specifically, the combination of the fixing stud 111 and the main controller fixing hole 121 is fastened by screws, so that a stable connection is formed between the upper shell 11 and the lower shell 12. This connection method effectively prevents the controller from loosening or shifting during operation, ensuring the stability and reliability of the controller structure. The design of the fixing stud 111 makes the assembly process simple and clear. The operator only needs to align the fixing stud 111 with the main controller fixing hole 121, and then use screws to fasten it. At the same time, when disassembly or maintenance is required, the upper shell 11 and the lower shell 12 can be easily separated by loosening the screws, which improves the convenience of maintenance. The fastening effect of the fixing stud 111 can effectively reduce the impact of external vibration on the internal components of the controller. This design is particularly important on mobile devices such as AGV carts, because it can help the controller resist vibration and impact caused by movement, ensuring the stable operation of the controller.

[0048] Optionally, the baseboard card 30 is provided with four antenna SMA sockets 32, two baseboard card main connectors 36 and six indicator lights; a side debugging interface is provided on the side of the baseboard card 30; a WiFi module 313 and a 5G module 314 are provided at the bottom of the baseboard card 30; and five Ethernet interfaces 22 and an encoder interface 27 are provided on the interface card 20.

[0049] Specifically, the four antenna SMA sockets 32, WiFi module 313 and 5G module 314 provided on the baseboard card 30 enable the controller to have powerful wireless communication capabilities. Two of the four antenna SMA sockets 32 are used to transmit WiFi signals, and two are used to transmit 5G network signals. Whether it is WiFi or 5G network, the controller can effectively access and achieve stable and high-speed data transmission. This is particularly important for mobile devices such as AGV carts, which can ensure that they can maintain real-time communication with external devices in different scenarios. The two main connectors and six indicator lights provided on the baseboard card 30, as well as the five Ethernet interfaces 22 and encoder interface 27 on the interface card 20, provide the controller with rich interface resources. This enables the controller to be easily connected to other devices or systems to achieve data interaction and sharing. At the same time, the design of the indicator light can intuitively display the working status of the controller, which is convenient for users to monitor and maintain. The side debugging interface set on the side of the baseboard card 30 provides convenience for the debugging of the controller. Users can perform various tests and debugging operations on the controller through these interfaces to ensure that it works properly and has stable performance. This greatly simplifies the debugging process and improves work efficiency.

[0050] Optionally, a baseboard card internal connector 31 is provided on the baseboard card 30, and an interface card internal connector 21 is provided at the bottom of the interface card 20. The baseboard card internal connector 31 is plugged with the interface card internal connector 21.

[0051] Specifically, through the plug-in mode of the internal connector, a close connection between the baseboard card 30 and the interface card 20 is achieved. This design enables the controller to have modular characteristics while maintaining a high degree of integration. The modular design not only facilitates assembly and disassembly, but also improves the convenience of maintenance, so that it can be easily carried out when a board needs to be replaced or repaired. The plug-in mode of the internal connector provides a stable and reliable electrical connection. Through the precise docking design, the signal transmission between the baseboard card 30 and the interface card 20 is ensured to be stable and correct, and the risk of failure caused by poor contact or looseness is reduced. Through the connection mode of the internal connector, the wiring between the baseboard card 30 and the interface card 20 is simplified. The traditional wiring method may require a large number of cables and connectors, while the design of the internal connector reduces the use of cables, making the internal structure of the entire controller more concise and clear. The plug-in mode of the internal connector makes the assembly of the baseboard card 30 and the interface card 20 faster and more convenient. During the production process, the operator only needs to align and plug the connectors on the two boards, without the need for complex wiring or debugging operations, thereby improving production efficiency.

[0052] Optionally, the functional signal interface and the side debugging interface are installed with waterproof gaskets.

[0053] Specifically, the waterproof gasket fits tightly around the interface to form an effective sealing barrier to prevent moisture or other liquids from penetrating into the controller through the interface. This design is particularly suitable for mobile devices such as AGV carts. When working outdoors or in humid environments, it can effectively resist the influence of adverse factors such as rain and fog on the controller. Moisture penetrating into the controller may cause serious consequences such as circuit short circuit and component damage, which in turn affects the stable operation of the entire system. The application of waterproof gaskets greatly reduces this risk and improves the reliability and stability of the equipment.

[0054] The working principle and beneficial effects of the utility model are:

[0055] The utility model uses a reasonable board stacking structure, combined with the design of the outer shell opening and the connector waterproof gasket, to make the ARM structure main controller space compact and improve the sealing to the IP65 level. The utility model integrates natural navigation related algorithms in the ARM core board 312, including SLAM navigation, GPS navigation, etc., which is suitable for scenarios where AGV has natural navigation requirements. In the AGV controller of the ARM architecture, the main body of the utility model supports 5G communication and WiFi communication, making the AGV main controller more integrated and adaptable to a wider range of scenarios, and can better support the application of AGV in large-scale, high-real-time scenarios.

[0056] The design of the controller housing and internal structure embodies a high degree of integration and modularity, aiming to improve the stability and reliability of the equipment. The housing effectively prevents the intrusion of moisture and dust through a reasonable interface layout and the use of waterproof gaskets, ensuring the normal operation of the controller in harsh environments. In the internal structure, the baseboard card 30 and the interface card 20 are tightly plugged in through an internal connector, which simplifies the wiring and improves production efficiency. At the same time, the setting of the heat dissipation device ensures stable heat dissipation of the controller during high-load operation and extends its service life. In addition, the fastening connection method of the fixing studs 111 and the screws enhances the stability of the structure and facilitates assembly and disassembly. In summary, the controller design not only optimizes the structural layout, but also improves the waterproof, heat dissipation and other performance, providing a stable and efficient control solution for mobile devices such as AGV carts.
