[0003] In the process of implementing the utility model, the inventors found that there are at least the following problems in this technology: However, the existing portable screens usually use heat dissipation modules with poor heat dissipation effect. The heat dissipation modules of the existing portable screens can only slowly dissipate the heat of the electronic components, but the heat after dissipation still remains inside the shell, so there will be heat accumulation, which may cause the electronic components to be damaged due to high temperature.

[0009] A temperature sensor and a PLC are also installed in the control room. A mounting groove is formed on the top wall of the outer frame. An indicator light is installed in the mounting groove. Both the temperature sensor and the indicator light are electrically connected to the PLC.
[0010] As a preferred embodiment, an interface is installed on the side of the outer frame facing away from the mounting slot, and a lithium battery is fixed inside the outer frame, and the interface is coupled to the lithium battery; personnel can charge the lithium battery through the interface, and the lithium battery is responsible for powering all power structures on the outer frame.
[0011] As a preferred embodiment, two screw holes are provided on the side of the circuit board facing away from the two side seats, and the heads of the two screws are respectively located in the two screw holes; so that the heads of the screws do not protrude from the circuit board, but can be hidden in the circuit board.
[0012] As a preferred embodiment, brackets are fixedly connected to the top wall and the bottom wall of the control room, and the two sides of the copper plate extend into the two brackets respectively; thereby facilitating the fixing of the copper plate.
[0013] As a preferred implementation, a heat dissipation groove is formed on the side of the outer frame facing away from the touch screen, and multiple heat sinks pass through the outer frame and enter the heat dissipation groove; thereby facilitating the heat of the multiple heat sinks to be dissipated to the outside through the heat dissipation groove.
[0014] As a preferred embodiment, a plurality of heat sinks are vertically arranged and distributed at equal intervals along a straight line; the heat conduction area is increased by setting up a plurality of heat sinks, which is beneficial to improving the heat dissipation efficiency.
[0015] In summary, the technical effects and advantages of the utility model are as follows:
[0016] The Xingshan wireless portable screen can conduct the heat released by the electronic components on the circuit board in real time through the thermal conductive paste and heat spreader, and dissipate the heat to the external environment through the heat sink. The temperature sensor cooperates with the PLC and indicator light to alarm when the temperature is high, so as to remind personnel to deal with it, which is conducive to reducing the probability of high temperature damage to the circuit board and extending its life.
[0017] The Star Flash wireless portable screen uses a temperature sensor in the control room to monitor the ambient temperature in the control room in real time. When the ambient temperature is higher than a set threshold, the temperature sensor transmits an electrical signal to the PLC, which in turn transmits an electrical signal to the indicator light, which lights up the indicator light, thereby reminding personnel to stop using the external frame or use other methods to dissipate heat. When the ambient temperature in the control room is lower than a set threshold, the indicator light goes out, thereby achieving a good high temperature warning function.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0024] Reference Figure 1-Figure 4 The StarLink wireless portable screen includes an outer frame 1 and a touch screen 2 embedded in a side wall of the outer frame 1. A control room 4 is formed inside the outer frame 1. A circuit board 5 is fixed in the control room 4. The portable screen adopts the StarLink technology. NearLink is a new generation of short-range wireless connection technology native to China. It is the first time that the Chinese communications industry has applied the experience and technology accumulated from following to leading the world for more than 30 years to the field of short-range wireless connection in an innovative way. The circuit board 5 is equipped with a corresponding wireless wifi module, and the wifi network card can be an ax200 model, so that it has the function of connecting to a wireless network for Internet access (similar to a smart phone). The specific technical principle is also included in the existing technology.
[0025] Two side seats 6 are fixedly welded on one side wall of the control room 4 close to the touch screen 2, and the circuit board 5 is attached to the two side seats 6. Two screws 7 are horizontally mounted on the circuit board 5 and penetrate into the side seats 6 respectively. Two screw holes are arranged on the side of the circuit board 5 facing away from the two side seats 6. The heads of the two screws 7 are respectively located in the two screw holes, so that the heads of the screws 7 do not protrude from the circuit board 5, but can be hidden in the circuit board 5;
[0026] A thermal conductive paste 8 and a copper plate 9 are provided in sequence on one side of the circuit board 5 facing away from the two side seats 6, wherein the thermal conductive paste 8 is tightly fitted with the circuit board 5 and the copper plate 9 respectively. The thermal conductive paste 8 may be of Laird 90000 model. Brackets 12 are fixedly connected to the top and bottom walls of the control room 4. Both sides of the copper plate 9 extend into the two brackets 12 respectively, so as to facilitate the fixing of the copper plate 9. A plurality of heat sinks 10 are fixedly welded on the side of the copper plate 9 facing away from the thermal conductive paste 8. A heat dissipation groove 11 is formed on the side of the outer frame 1 facing away from the touch screen 2. The plurality of heat sinks 10 all pass through the outer frame 1 and enter the heat dissipation groove 11, so as to facilitate the heat of the plurality of heat sinks 10 to be dissipated to the outside through the heat dissipation groove 11. The plurality of heat sinks 10 are vertically arranged and evenly spaced along a straight line. The plurality of heat sinks 10 are arranged to increase the heat conduction area, which is beneficial to improving the heat dissipation efficiency.
[0027] A temperature sensor 13 and a PLC 14 are also installed in the control room 4. A mounting groove 15 is formed on the top wall of the outer frame 1. An indicator light 16 is installed in the mounting groove 15. The temperature sensor 13 and the indicator light 16 are both electrically connected to the PLC 14. The temperature sensor 13 can refer to the technical principle of the pt100 model, and the PLC 14 can refer to the technical principle of the STC89C51 model and other models. An interface 3 is installed on the side of the outer frame 1 facing away from the mounting groove 15, and a lithium battery 17 is fixed inside the outer frame 1. The interface 3 is coupled to the lithium battery 17 so that personnel can charge the lithium battery 17 through the interface 3. The lithium battery 17 is responsible for powering all power structures on the outer frame 1.
[0028] The Xingshan wireless portable screen: When in use, its technical principle is the same as that of the smart mobile terminal in the prior art. The corresponding function can be realized by touching the touch screen 2 with a human finger. It will not be described here, but its heat dissipation principle and high temperature warning principle will be described in detail - the electronic components on the circuit board 5 will release heat when working. Since the thermal conductive paste 8 is tightly attached to the circuit board 5, the heat is directly transferred to the thermal conductive paste 8, and then to the copper plate 9, and then enters the heat exhaust groove 11 through a plurality of heat sinks 10. The heat exhaust groove 11 is directly exposed to the outside world, so that the heat can be dissipated to the external environment, which is better than the passive heat dissipation effect in the prior art;
[0029] The temperature sensor 13 monitors the ambient temperature in the control room 4 in real time. When the ambient temperature is higher than a set threshold (for example, 50°C), the temperature sensor 13 transmits an electrical signal to the PLC 14, so that the PLC 14 transmits an electrical signal to the indicator light 16, which lights up the indicator light 16, thereby reminding personnel to stop using the external frame 1, or use other methods to dissipate heat. When the ambient temperature in the control room 4 is lower than a set threshold (for example, 30°C), the indicator light 16 goes out, thereby achieving a good high temperature warning function.
[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
