Description

Technical Field

[0001] This invention relates to industrial control equipment, and more particularly to intelligent host systems. Background Technology

[0002] With continuous economic and social development and progress, the level of industrialization is also constantly improving. For traditional manufacturing industries, with the continuous increase in labor costs and the ever-increasing demands for production capacity, traditional production methods relying on manual labor or semi-automatic production lines are no longer sufficient to meet the needs of modern production. To meet the needs of automated production, intelligent industrial hosts that play a control role are indispensable for various automated equipment.

[0003] An industrial host, also known as an industrial control main machine, is short for industrial control computer. It is a device used to monitor and control the machinery, production processes, and data parameters used in the production process. To improve ease of use, there are currently integrated industrial intelligent hosts on the market that combine a touch screen display with the host, which improves operational efficiency and is easy to carry. A similar industrial host is disclosed in utility model patent CN215683026U.

[0004] The aforementioned industrial host, if operated in a low-temperature environment, is prone to causing the liquid crystal in the display screen to freeze or crack, ultimately resulting in unclear display or even damage to the display screen, so further improvements are needed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent host that can heat the display screen using hot air blown by a cooling fan in low-temperature environments. This not only prevents the display screen from weakening or being damaged, but also reduces heating energy consumption.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A smart host includes a main housing and a display screen mounted on the main housing. The main housing comprises a first housing and a second housing joined together vertically. A circuit board parallel to the display screen is disposed within the first housing, and control circuitry is integrated on the circuit board. The display screen is electrically connected to the control circuitry. Two cooling fans are disposed on the surface of the circuit board furthest from the display screen. The air inlets of the cooling fans and the surface of the circuit board closest to the cooling fans maintain a first gap corresponding to that of the first housing. A sealing plate is fitted over the second housing furthest from the display screen, and a second gap is maintained between the sealing surface of the sealing plate and the air outlet of the cooling fans, corresponding to that of the second housing. The display screen is located furthest from the main housing. The display screen has a flat surface with air supply ducts on both sides. The air supply ducts are arranged along the edges of the display screen. Air outlets are opened along the length of the opposite sidewalls of the two air supply ducts. Air guide blocks extend from the air supply ducts towards the sealing plate, and the air guide blocks extend to the second housing near the sealing plate. Air guide grooves connected to the air outlets are opened in the air guide blocks. First heat dissipation holes are opened on the sidewalls of the first housing corresponding to the air supply ducts, and second heat dissipation holes are opened on the sidewalls of the second housing corresponding to the air supply ducts. The sealing plate has two heat dissipation holes on its surface, each corresponding to one of the two cooling fans. The heat dissipation holes are equipped with adjustment mechanisms, which have two states:

[0008] In the first state, when the adjustment mechanism opens the heat dissipation vent, the first heat dissipation hole is open and the second heat dissipation hole is closed;

[0009] In the second state, when the adjustment mechanism closes the heat dissipation vent, the first heat dissipation vent closes and the second heat dissipation vent opens.

[0010] Using the above solution, the cooling fan mounted on the circuit board can promptly remove the heat generated by the circuit board. During this process, the cooling fan's outlet blows hot air towards the sealing plate. When the smart host is in a normal or high-temperature environment, the adjustment mechanism is placed in the first state to open the heat dissipation vent and the first heat dissipation hole, while simultaneously closing the second heat dissipation hole. At this time, driven by the cooling fan, air above the display screen can enter the air guide groove of the corresponding air guide block through the air outlets on the two air supply pipes, then enter the air inlet of the cooling fan through the first heat dissipation hole, and finally be discharged from the cooling fan outlet back to the heat dissipation vent, achieving a cooling effect. Conversely, when the smart host is in a low-temperature environment, the adjustment mechanism is placed in the second state to close the heat dissipation vent and the second heat dissipation hole, while simultaneously opening the second heat dissipation hole. At this time, the hot air blown out by the cooling fan can be redirected by the sealing plate, then enters the air guide groove of the air guide block through the second heat dissipation hole, and is blown upwards within the air guide groove, finally being blown outwards through the air outlets on the air supply pipes. In this state, the hot air blown out of the air outlet can form a heat insulation layer on the surface of the display screen, preventing the display screen from malfunctioning due to low temperature, while reducing the display screen's heating energy consumption.

[0011] Preferably, the two side walls of the first housing that do not have the first heat dissipation hole are provided with a third heat dissipation hole.

[0012] With the above solution, when the adjustment mechanism is in the second state, the cooling fan can supplement air through the third heat dissipation hole to ensure unobstructed airflow inside the main casing, while the third heat dissipation hole will not interfere with the normal function of the first heat dissipation hole.

[0013] Preferably, the transition between the air outlet and the air guide trough has a first air guide arc surface.

[0014] The above solution ensures that the airflow at the junction of the air outlet and the air guide channel can pass smoothly, thus guaranteeing the efficiency of air intake and exhaust.

[0015] Preferably, the end of the air guide slot near the sealing plate and the connection point with the second heat dissipation hole have a second air guide arc surface.

[0016] By adopting the above solution, the airflow at the junction of the air guide slot near the sealing plate and the second heat dissipation hole can pass smoothly, further improving the efficiency of air intake and exhaust.

[0017] Preferably, the cooling fan is located close to the plane of the circuit board and has support columns at its four corners, with the support columns fixed to the surface of the circuit board.

[0018] Using the above solution, the support column can effectively allow the cooling fan to be suspended above the circuit board, so that an initial gap can be created between the two.

[0019] Preferably, the adjustment mechanism includes a cover disposed on the outer surface of the sealing plate and a sliding plate disposed on the inner wall of the main housing. There are two covers that cover two heat dissipation vents respectively. There are two sliding plates that are respectively attached to the two side walls of the main housing corresponding to the air guide block. The sealing plate has guide openings on both sides. A connecting rod slides through the guide openings. The two ends of the connecting rod are respectively fixed to the cover and the sliding plate.

[0020] When the adjustment mechanism is in the first state, the cover moves away from the heat dissipation port to open the heat dissipation port, and the sliding plate slides to the position of the second heat dissipation hole to close the second heat dissipation hole, while the first heat dissipation hole remains open.

[0021] When the adjustment mechanism is in the second state, the cover closes the heat dissipation port, the sliding plate slides to the position of the first heat dissipation hole to close the first heat dissipation hole, and the second heat dissipation hole remains open.

[0022] By adopting the above scheme, the above structure can effectively realize the state switching of the adjustment mechanism.

[0023] Preferably, a connecting plate is provided between the two caps, and a gripping element is provided on the surface of the connecting plate away from the cap.

[0024] The above solution allows users to more easily remove both covers from the two heat dissipation vents simultaneously, improving operational efficiency and convenience.

[0025] Preferably, the grip is pivotally connected to the surface of the connecting plate.

[0026] The above solution makes it easier to store the gripping parts, making it more user-friendly.

[0027] This invention, employing the above technical solution, achieves significant technical effects: the cooling fan mounted on the circuit board can promptly remove the heat generated by the circuit board. During this process, the cooling fan's outlet blows hot air towards the sealing plate. When the smart host is in a normal or high-temperature environment, the adjustment mechanism is placed in the first state to open the heat dissipation vent and the first heat dissipation hole, while simultaneously closing the second heat dissipation hole. At this time, driven by the cooling fan, air above the display screen can enter the air guide groove of the corresponding air guide block through the air outlets on the two air supply pipes, then enter the air inlet of the cooling fan through the first heat dissipation hole, and finally be discharged from the cooling fan outlet to the heat dissipation vent, achieving a cooling effect. Conversely, when the smart host is in a low-temperature environment, the adjustment mechanism is placed in the second state to close the heat dissipation vent and the second heat dissipation hole, while simultaneously opening the second heat dissipation hole. At this time, the hot air blown out by the cooling fan can be redirected by the sealing plate, then enters the air guide groove of the air guide block through the second heat dissipation hole, and is blown upwards within the air guide groove, finally being blown outwards through the air outlets on the air supply pipes. In this state, the hot air blown out of the air outlet can form a heat insulation layer on the surface of the display screen, preventing the display screen from malfunctioning due to low temperature, while reducing the display screen's heating energy consumption.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 6As shown, this embodiment discloses a smart host, including a main housing 1 and a display screen 2 disposed on the main housing 1, the display screen 2 preferably being a touch display. The main housing 1 includes a first housing 3 and a second housing 4 spliced ​​together, the first housing 3 and the second housing 4 preferably being fixed by ultrasonic welding, or they can be fixed by glue. A circuit board 5 parallel to the display screen 2 is disposed inside the first housing 3, and the four corners of the circuit board 5 are fixed to the back of the display screen 2 by screws 28. A control circuit (not shown) is integrated on the circuit board 5, and the display screen 2 is electrically connected to and controlled by the control circuit (not shown). Two cooling fans 6 are disposed on the surface of the circuit board 5 away from the display screen 2, and the cooling fans 6 are electrically connected to and controlled by the control circuit (not shown). The cooling fans 6 are close to the plane of the circuit board 5 and each of its four corners is provided with a support post 21, the support post 21 being fixed to the surface of the circuit board 5 by screws (not shown), so that the air inlet 29 of the cooling fan 6 and the surface of the circuit board 5 close to the cooling fan 6 maintain a first distance 7 corresponding to the first housing 3. A sealing plate 8 is fitted onto the second housing 4 at a position away from the display screen 2. The sealing plate 8 is preferably fixed to the second housing 4 by ultrasonic welding, but it can also be fixed by adhesive. A second gap 9 is maintained between the sealing surface of the sealing plate 8 and the air outlet 30 of the cooling fan 6, corresponding to the second housing 4. Air supply pipes 10 are provided on both sides of the display screen 2 away from the plane of the main housing 1. The air supply pipes 10 are arranged along the edge of the display screen 2. Air outlets 11 are opened on the opposite sidewalls of the two air supply pipes 10 along their length. Air guide blocks 12 extend from the air supply pipes 10 toward the sealing plate 8. The air guide blocks 12 extend to the position of the second housing 4 near the sealing plate 8. An air guide groove 13 communicating with the air outlet 11 is opened in the air guide block 12. The first housing 3 has first heat dissipation holes 14 on each side wall corresponding to the air supply pipe 10, and the second housing 4 has second heat dissipation holes 15 on each side wall corresponding to the air supply pipe 10. The sealing plate 8 has two heat dissipation openings 16 on its surface, each corresponding to one of the two cooling fans 6. Both heat dissipation openings 16 are circular to accommodate the shape of the air outlet 30 of the cooling fans 6. An adjustment mechanism 17 is provided on the heat dissipation opening 16, and the adjustment mechanism 17 has two states:

[0039] In the first state, when the adjustment mechanism 17 opens the heat dissipation port 16, the first heat dissipation hole 14 is opened and the second heat dissipation hole 15 is closed;

[0040] In the second state, when the adjustment mechanism 17 closes the heat dissipation port 16, the first heat dissipation hole 14 is closed and the second heat dissipation hole 15 is opened.

[0041] In this embodiment, the adjustment mechanism 17 includes a cover 22 disposed on the outer surface of the sealing plate 8 and a sliding plate 23 disposed on the inner wall of the main housing 1. Two covers 22 are provided and respectively cover two heat dissipation vents 16. Two sliding plates 23 are provided and respectively adhere to the two side walls of the main housing 1 corresponding to the air guide block 12. The length of the sliding plate 23 is the same as the length of the inner side wall of the main housing 1, and its height is half the height of the inner wall of the main housing 1. Guide openings 24 are provided on both sides of the sealing plate 8, with three guide openings 24 on each side, arranged at equal intervals along the edge of the sealing plate 8. A connecting rod 25 of equal length to the height of the main housing 1 slides through the guide opening 24. The two ends of the connecting rod 25 are fixed to the cover 22 and the sliding plate 23 respectively, so that the cover 22 can move closer to or further away from the heat dissipation vents 16 in a direction perpendicular to the sealing plate 8, while simultaneously driving the sliding plate 23 to slide synchronously, thereby switching the working state of the adjustment mechanism 17.

[0042] Specifically, when the adjustment mechanism 17 is in the first state, the cover 22 moves away from the heat dissipation port 16 to open the heat dissipation port 16, the sliding plate 23 slides to the position of the second heat dissipation hole 15 to close the second heat dissipation hole 15, and the first heat dissipation hole 14 remains open.

[0043] Conversely, when the adjustment mechanism 17 is in the second state, the cover 22 closes the heat dissipation port 16 to shut it off, the sliding plate 23 slides to the position of the first heat dissipation hole 14 to close it off, and the second heat dissipation hole 15 remains open.

[0044] To enable the two covers 22 to operate synchronously, a connecting plate 26 is connected between the two covers 22. A gripping member 27 is provided on the surface of the connecting plate 26 away from the cover 8. The gripping member 27 is pivotally connected to the surface of the connecting plate 26 via a hinge 31, making it easy to store the gripping member 27.

[0045] In order to ensure that the regulating mechanism 17 can maintain smooth airflow in the main housing 1 in the second state, the two side walls of the first housing 3 that do not have the first heat dissipation hole 14 are provided with the third heat dissipation hole 18.

[0046] To improve the smoothness of airflow turning within the air guide duct 13, a first air guide arc surface 19 is provided at the junction of the air outlet 11 and the air guide duct 13. A second air guide arc surface 20 is provided at the junction of the end of the air guide duct 13 near the sealing plate 8 and the second heat dissipation hole 15.

[0047] The specific usage process is as follows:

[0048] The cooling fan 6 mounted on the circuit board 5 can promptly remove the heat generated by the circuit board 5. During this process, the air outlet 30 of the cooling fan 6 can blow hot air towards the sealing plate 8. When the smart host is in a normal temperature or high temperature environment, the holding member 27 pulls the connecting plate 26 and the sealing covers 22 at both ends of the connecting plate 26 away from the sealing plate 8 to open the heat dissipation vent 16. At the same time, the connecting rod 25 pulls the sliding plate 23 to the inner wall of the second housing 4 to open the first heat dissipation hole 14 and close the second heat dissipation hole 15, finally putting the adjustment mechanism 17 into the first state (e.g., Figure 7 (As shown). At this time, driven by the cooling fan 6, the air above the display screen 2 can enter the air guide groove 13 of the corresponding air guide block 12 through the air outlet 11 on the two air supply pipes 10, and then enter the air inlet 29 of the cooling fan 6 through the first heat dissipation hole 14, and finally be discharged to the heat dissipation port 16 through the air outlet 30 of the cooling fan 6 to achieve the heat dissipation effect.

[0049] Conversely, when the smart host is in a low-temperature environment, the connecting plate 26 and the caps 22 at both ends of the connecting plate 26 are pushed inward to close the heat dissipation vent 16. At the same time, the connecting rod 25 pushes the sliding plate 23 into the first housing 3 to close the first heat dissipation vent 14 and open the second heat dissipation vent 15, ultimately putting the adjustment mechanism 17 into the second state (e.g., Figure 8 (As shown). At this time, the hot air blown out by the cooling fan 6 can be redirected by the sealing plate 8, and then enters the air guide groove 13 of the air guide block 12 through the second heat dissipation hole 15, and is blown upward in the air guide groove 13, and finally blown outward through the air outlet 11 on the air supply pipe 10. In this state, the hot air blown out by the air outlet 11 can form a heat insulation layer on the surface of the display screen 2, preventing the display screen 2 from malfunctioning due to low temperature, and at the same time reducing the heating energy consumption of the display screen 2.
