[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The first embodiment

[0036] The embodiment of the present invention provides a host device, which can be applied to an automated control system and can control and implement the logic of the entire system.

[0037] Please refer to Figure 1-6 , the host device is applied to a programmable logic controller (PLC) system. The host device includes a housing 10. One side of the housing 10 is provided with a power socket 15, and the power socket 15 is used to connect to a power connector on a power device to supply power to the host device; the front of the housing 10 includes a communication function area 31, a display function area 33 and a port function area 32 that are fixedly arranged with each other; on the surface of the housing where the communication function area 31 is located, at least one installation inclined surface is provided. A communication interface 12 is provided in the communication function area. The interface section of the communication interface 12 is flush with the installation inclined surface, and the inclined surface forms an angle of 0-90° with the bottom plane of the housing; a port 13 is provided in the port function area 32, and the port 13 includes a number of IO terminals.

[0038] The host device is the core control device in the PLC system and can realize the control and logic implementation of the entire system. Please refer to Figure 7 , which shows the system composition of the host device. It can be connected to a splitter through an EtherCAT bus, and the splitter can continue to be extended through the EtherCAT bus to connect other communication adapters, etc. The splitter only functions as an extension and forwarding, and the actual control is still implemented by the host device.

[0039] The host device in this embodiment, in terms of its structure, includes a housing 10 and various facilities provided on the housing 10. Among them, due to the expansion connection characteristics of the host device, it usually needs to be connected to a power supply device and more other electronic devices, and the way of its expansion connection is in series. Therefore, the two sides of the host device are directly used to connect to other electronic devices, including but not limited to, a power socket 15 provided on one side of the housing 10 of the host device. This power socket 15 is used to connect to the power connector on the power supply device, so that the power supply of the power supply device can be provided to the host device through the power connector passing through the power socket 15.

[0040] To improve the reliability of the connection between the host device and the power supply device, on the housing 10 of the host device, several first fixing members 19 are provided on the same side as the power socket 15. The first fixing members 19 are used for connecting and cooperating with the second fixing members provided on the power supply device to achieve a fixed connection between the host device and the power supply device. The connection between the first fixing members 19 and the second fixing members can improve the reliability of the connection between the host device and the power supply device.

[0041] Specifically, the first fixing member 19 can be a fixing post or a connection hole, and the second fixing member is the corresponding connection hole or fixing post. The sizes of the fixing post and the connection hole are matched with each other to form a tight contact. The first fixing member 19 and the second fixing member can be a mutually cooperating connection hole and a connection shaft, where the connection hole and the connection shaft are tightly connected. The connection shaft can be cylindrical, or a combination of a cone and a cylinder, or stepped. In this embodiment, the first fixing member 19 can be used as the connection hole and the second fixing member as the connection shaft, or the first fixing member 19 can be used as the connection shaft, and the corresponding second fixing member is used as the connection hole.

[0042] Please refer to Figure 1 , multiple functional areas are provided on the front surface of the housing 10, that is, a communication function area 31, a display function area 33, and a port function area 32. Among them, at least one installation inclined surface is provided on the surface of the housing where the communication function area 31 is located. A communication interface 12 is provided in the communication function area. The interface end face of the communication interface is flush with the installation inclined surface, and the installation inclined surface forms an angle of 0 - 90° with the bottom plane of the housing; ports 13 are provided in the port function area, and the ports include several IO terminals. A display unit is provided on the display function area 33 for display.

[0043] In the communication interface 12 provided on the communication function area of the housing 10, it is mainly used to connect with other devices and perform signal interaction communication with the connected devices. The host device includes several communication interfaces 12 for expansion, and each communication interface 12 for expansion can connect one device. The communication interface 12 includes Ethernet and EtherCAT, or communication methods such as RS232, RS485, CAN, and Modbus. Among them, Ethernet is mainly used to connect the Ethernet port of the PC. Please refer to Figure 7 , Figure 7 A possible networking method is shown in. The networking of EtherCAT is flexible. According to the specific requirements of local area networking, the device connected to the communication interface 12 used by the host device may be a splitter or an adapter. It can be understood that in actual networking, in an EtherCAT network system, usually one host device, several splitters, and communication adapters are configured.

[0044] The interface direction of the communication interface 12 is set obliquely. The way of its oblique setting is to set an installation inclined surface on the housing. The end face of the communication interface 12 is flush with the installation inclined surface, and an angle of 0 to 90 degrees is formed between the installation inclined surface and the bottom surface of the housing. The angle of 0 to 90 degrees mentioned here means that the communication interface 12 can be parallel to the bottom surface of the housing 10, or perpendicular to the bottom surface of the housing 10, or present an intermediate angle, that is, the inclined angle. Among them, the inclined direction of the communication interface 12 can be inclined upward or inclined downward. It can be understood that in some scenarios, the inclined communication interface 12 is easier to plug and unplug compared with the horizontal one. The inclined communication interface 12 can be realized by using a network connector with an inclined plug interface itself, or the network connector with a traditional straight plug interface can be set obliquely on the circuit board or the whole circuit board can be inclined. In this embodiment, the communication interface 12 is an RJ45 communication interface 12. In other specific embodiments, the communication interface 12 can also be other types of interfaces as long as it can access the corresponding transmission line to realize the function of network data transmission.

[0045] Since the communication interface 12 is inclined and there is a certain angle between it and the outer shell plane of the host device, for the rationality and aesthetics of plugging and unplugging, in some embodiments, the outer surface shape of the part of the housing 10 located in the communication function area 31 corresponds to the inclined direction of the communication interface 12. That is to say, the housing 10 of the host device around the communication interface 12 is directly matched with the inclined direction of the communication interface 12. Usually, such a match means that regardless of the inclined direction of the communication interface 12, the part of the housing 10 around it is perpendicular to the inclined direction of the communication interface 12, so that the outer shell part corresponding to the outlet of the communication interface 12 is flush.

[0046] In some embodiments, when the number of communication interfaces 12 is greater than or equal to 2, at least one communication interface 12 is disposed on the installation inclined surface, and the communication interfaces 12 are arranged vertically or horizontally in the communication function area 31. That is to say, if there are multiple communication interfaces 12, then at least one of the communication interfaces 12 is inclined, and the other communication interfaces 12 may not be inclined; all the communication interfaces 12 can be inclined at a consistent inclination angle. If there are multiple communication interfaces 12, then the arrangement between these communication interfaces 12 can be horizontal or vertical.

[0047] The display function area 33 and the port function area 32 are located on the right side of the communication function area 21, and the display function area 33 is at least located above the port function area 32. Such an arrangement makes the space utilization on the front of the housing of the host as reasonable as possible and relatively beautiful. Among them, the display function area 33 is at least located above the port function area 32, which means that the display function area 33 and the port function area 32 are generally arranged vertically, but there may be some areas of the display function area 33 that are not above the port function area 32, or there may be some areas of the port function area 32 that are not below the display function area 33.

[0048] In some embodiments, at least one display unit 16 is disposed on the display function area 32, and the display content of the display unit 16 is at least used to prompt the usage of the IO terminals in the port function area. The display unit 16 can be a display screen or an LED indicator array, which includes several LED indicators. The display of the display unit 16 corresponds to the number of IO terminals in the port 13 and can be used to indicate the usage or occupancy of the IO terminals. Specifically, the display unit 16 can include several LED lights, and the number of LED lights can directly correspond to the number of IO terminals in the port 13, and the usage of the IO terminals in the port 13 can be indicated by the on / off of the LED lights. In addition, the display unit can also include a display panel composed of digital tubes, liquid crystal displays, etc. Compared with LED lights, the display panel can display more content.

[0049] Within the port function area 32 on the front of the housing 10 of the host device, a port 13 is further provided. The port 13 includes a plurality of terminals, and the terminals include IO terminals and ground terminals. These terminals are detachable on the housing 10 of the host device. Since the terminals are detachable, it is more convenient to pick and place when the terminals are damaged, and it is also more convenient during installation. Moreover, the setting of terminals of various specifications can be achieved. Among them, the port 13 may include at least one row of vertically arranged terminals, and the terminals extend out of the housing. That is to say, the outer edge of the terminals protrudes from the housing, which is convenient for connection. Specifically, the port 13 includes at least one row of vertically arranged terminals; the type of the port may include at least one of an 8-point port, a 16-point port, a 64-point port, or a 32-point port.

[0050] Within the display function area 33 of the housing 10 of the host device, at least one display panel 16 is further provided. Among them, the display of the at least one display panel 16 corresponds to the number of IO terminals in the port 13, and it can be used to indicate the usage or occupancy status of the IO terminals. That is, the display content of the display panel 16 is at least used to prompt the usage status of the IO terminals. Specifically, the display panel 16 may include a plurality of LED lights, and the number of LED lights can directly correspond to the number of IO terminals in the port 13. The usage status of the IO terminals in the port 13 can be indicated by the lighting and extinguishing of the LED lights.

[0051] In some embodiments, the front of the housing 10 of the host device further includes an expansion function area 34. The expansion function area 34 is fixedly arranged in any edge area on the front of the housing 10 of the host device, or between any two other function areas. An expansion interface and / or a function interface are provided on the expansion function area 34. Among any two other function areas, the function areas may include a communication function area 31, a display function area 33, a port function area 32, etc. The expansion function area 34 can be arranged at the edge or in the middle.

[0052] At a position on the housing 10 corresponding to the extended function area 34, a protective cover 17 is also provided. The protective cover 17 is movably connected to the housing 10, and in the protected state, the protective cover 17 covers the extended function area 34. For the components on the host device, the commonly used components can be kept exposed, while for some infrequently used components, or some components or function buttons that need to be used with caution, such components can be arranged in the extended function area 34, and then through the setting of the protective cover 17, they can be hidden. This hiding can be switched along with the movable connection between the protective cover 17 and the housing 10, that is, the switching between the protected state and the non-protected state. In the protected state, the protective cover 17 covers the extended function area 34, which is equivalent to the protective cover 17 covering at least part of the position on the housing 10, and on the covered part, some extended interfaces and / or function interfaces that need to be hidden can be arranged on the housing 10; while in the second state, the protective cover 17 changes the movable connection state with the housing 10 and no longer blocks the extended function area 34, so that the hidden components can be exposed. The protective cover can be made of non-transparent material, or can be made of transparent or semi-transparent material. The transparent or semi-transparent material can help the user view the components extended in the extended function area therein without opening the protection. The protective cover 17 protrudes from the outer surface of the housing 10, and the outer surface shape of the protective cover 17 is arc-shaped.

[0053] The movable connection between the protective cover 17 and the housing 10 can be a rotational connection formed by a hinge, or a movable connection formed by a buckle, etc. The present embodiment does not specifically limit it.

[0054] In the present embodiment, the extended interface belongs to an infrequently used component, which can include at least one of a USB interface, an SD card interface, etc., and is only needed in certain specific scenarios; the function interface represents an interface required for some specific functions of the host device. For example, the function interface can include at least one of a reset interface, a stop interface, etc. Due to the particularity of their functions, these interfaces need to be protected from being easily triggered, so they can be hidden usually.

[0055] In some embodiments, a heat dissipation component 11 is further included and arranged on the housing 10; the heat dissipation component 11 includes a heat dissipation hole array arranged on at least one surface of the housing 10, and the heat dissipation hole array includes a plurality of heat dissipation holes 111, and the heat dissipation holes 111 are formed by three strip-shaped through holes intersecting at one point.

[0056] In this embodiment, a heat dissipation hole array is provided on at least one surface of the host device. The heat dissipation hole array is composed of a number of heat dissipation holes 111 arranged in an array, and is used to discharge the heat in the host device through the heat dissipation holes 111. Among them, in this embodiment, for the consideration of heat dissipation effect, the shape of the heat dissipation hole 111 is set to be composed of three strip-shaped through holes intersecting at one point. Please refer to Figure 3-4 , the shape of a single heat dissipation hole 111 is equivalent to forming an arrow. Such a setting method is equivalent to a heat dissipation hole 111 being formed by three strip-shaped heat dissipation holes 111, and its heat dissipation area is relatively large. Moreover, for the heat dissipation hole 111 set in this way, since its edge is irregular, it can, to a great extent, prevent foreign objects from falling into the interior of the host device through the heat dissipation hole 111, such as Figure 3 、 4 shown.

[0057] In some embodiments, in the heat dissipation hole array, the heat dissipation holes 111 are arranged in parallel. Each heat dissipation hole 111 in the heat dissipation hole array is arranged in an array in a parallel manner, and the distance between adjacent single rows of heat dissipation holes 111 is equal, and the distance between the heat dissipation holes 111 in each row is also equal. The purpose of such a setting can improve its aesthetics and also reduce the manufacturing process difficulty.

[0058] In some embodiments, in the heat dissipation hole array, the heat dissipation holes 111 are arranged in a staggered manner according to the inclination direction of any one of the three strip-shaped through holes forming the heat dissipation hole 111. Since the shape of the heat dissipation hole 111 in the embodiment of the present application is composed of three strip-shaped holes and has a certain directionality, in order to further increase the coverage area of the heat dissipation hole 111 and improve the heat dissipation efficiency, the heat dissipation holes 111 are arranged in a staggered manner according to the inclination direction of the strip-shaped holes, which improves the compactness between the heat dissipation holes 111 and increases the heat dissipation area occupied by the heat dissipation holes 111. The heat dissipation component 11 in this embodiment can be manufactured by injection molding, stamping and other methods.

[0059] In some embodiments, the heat dissipation components 11 are disposed on the upper and lower surfaces of the housing 10 of the host device, and a heat dissipation convection is formed between the heat dissipation components 11. For better heat dissipation effect, the heat dissipation components 11 generally include at least two, which are respectively disposed on two opposite surfaces of the housing 10, so that a heat dissipation convection can be formed, that is, cold air enters from one side and hot air exits from the other side, and there is basically no air duct interference between the cold air and the hot air. The left and right sides of the host device are generally used for installing other devices, such as power supply devices, interface devices, etc., and a communication interface 12 and several terminals are provided on the front surface of the host device, wherein the terminals are arranged vertically, including 16 IO terminals and 2 ground terminals. On the back of the host device, a clip assembly 20 is provided for mounting the host device to other devices. Therefore, the most suitable spaces on the housing 10 of the host device for setting the heat dissipation components 11 are the top and bottom spaces, such as Figure 3 and 4 shown.

[0060] In addition, the housing 10 of the host device may include a front shell 101 and a rear cover 102 that are detachably connected to each other; the shapes of the front shell 101 and the rear cover 102 are concave-convex shapes that match each other, and the front shell 101 and the rear cover 102 are connected by a snap connection. Specifically, the assembly handover of the housing 10 can be formed along the top surface - side surface - bottom surface - another side surface - top surface of the housing 10, and the housing 10 is separated into two parts along the front and back, namely the front shell 101 and the rear cover 102 respectively.

[0061] In some embodiments, a connector 110 and / or a battery slot 112 are further provided on the top of the housing of the host device, and the connector 110 and / or the battery slot 112 are detachably connected to the housing 10. The connector 110 therein can be a 485 or 232 connector, and the battery slot 112 can be a slot for a button battery, a dry battery, a storage battery, a lithium battery, etc. Whether it is the connector 110 or the slot 112, it can be a structure that is detachable from the housing.

[0062] This embodiment provides a host device, which is applied to a programmable logic controller (PLC) system. The host device includes a housing 10.
