Description

Technical Field

[0001] This invention relates to the field of digital home smart terminal equipment technology, specifically to a ruggedized display and control terminal. Background Technology

[0002] Digital home smart terminal devices are intelligent devices that use computer, network communication and other technologies to organically integrate home life-related subsystems, realize information collection, processing, output and linkage control, and provide users with a comfortable, safe and convenient home experience. They usually have interactivity, network access capabilities and data processing capabilities, can directly interact with users and connect to a wider network environment.

[0003] Display and control terminals (also known as display control terminals) are common devices in digital home smart terminal equipment. They support functions such as audio, video, and data, and are devices that integrate display output and interactive control functions. They realize the visualization of information and the input of user commands through human-computer interaction interfaces (such as screens, touch screens, buttons, etc.). In the production process of display and control terminals, high-strength engineering plastics, metal alloys, or carbon fiber composite materials are usually used to reinforce and optimize the display and control equipment. This gives the display and control equipment impact resistance, corrosion resistance, high temperature resistance, and low temperature resistance, ensuring stable operation of the equipment under harsh conditions, significantly improving its reliability, safety, and economy, while expanding application scenarios and enhancing user experience.

[0004] Currently, to enhance the durability and stability of the interface components of display and control terminals, high-strength materials are typically used in ruggedized display and control terminals. While these materials possess excellent mechanical properties, they can affect the heat dissipation of the interface components. Under prolonged operation or high load conditions, the interface components of ruggedized display and control terminals are more prone to overheating, causing the internal temperature of the interface to rise. Long-term high-temperature environments can accelerate the aging and damage of various components in the interface components of the display and control terminal, easily leading to signal transmission interruptions or distortions, affecting the accuracy and speed of data transmission, reducing the overall reliability of the equipment, increasing maintenance costs, and in severe cases, the high temperature of the interface may even cause safety accidents such as fires. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a ruggedized display and control terminal, which can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a ruggedized display and control terminal, comprising: The machine body has an interface portion fixedly connected to its outer surface, and a wire connector is inserted into the interface portion. The interface includes a fixed front ring, which is fixedly connected to the outer surface of the body. A fixed rod is fixedly connected to the outer surface of the fixed front ring. A fixed rear ring is fixedly connected to the fixed front ring via the fixed rod. A fixed cylinder is fixedly connected to the side of the fixed rear ring near the fixed front ring. A conductor is fixedly connected inside the fixed cylinder. An outer ring is fixedly connected to the inner wall of the fixed front ring. An inner ring is fixedly connected to the inner wall of the outer ring. A telescopic cylinder is fixedly connected to the inner wall of the inner ring. A telescopic rod is slidably connected inside the telescopic cylinder. A sealing patch is fixedly connected to the end of the telescopic rod away from the telescopic cylinder.

[0007] Furthermore, a forward protruding ring is rotatably connected to the inner wall of the outer ring, and a rotating ring is fixedly connected to the inner wall of the forward protruding ring. A pushing groove is formed on the outer surface of the rotating ring, and a pushing wheel is rotatably connected to the outer surface of the sealing patch. The pushing wheel is slidably connected inside the pushing groove.

[0008] Furthermore, a first rotating cylinder is rotatably connected between the fixed rear ring and the outer ring. A first ring body is fixedly connected to the inner wall of the first rotating cylinder. A telescopic shaft is slidably connected to the outer surface of the first ring body. A rear protruding ring is fixedly connected to the end of the telescopic shaft away from the first ring body.

[0009] Furthermore, a second rotating cylinder is rotatably connected to the side of the fixed rear ring near the first rotating cylinder. The second rotating cylinder is located inside the first rotating cylinder. A second ring body is fixedly connected to the inner wall of the second rotating cylinder, and a fan blade assembly is fixedly connected to the inner wall of the second ring body.

[0010] Furthermore, a third rotating cylinder is rotatably connected to the side of the fixed rear ring near the first rotating cylinder. The third rotating cylinder is located between the first rotating cylinder and the second rotating cylinder. A third ring body is fixedly connected to the inner wall of the third rotating cylinder, and a spiral guide rail is provided on the inner wall of the third ring body.

[0011] Furthermore, a slide rail is fixedly connected to the side of the fixed rear ring near the fixed front ring, a slide frame is slidably connected inside the slide rail, a push disc is fixedly connected to the outer surface of the slide frame, the push disc is slidably sleeved on the outer circumference of the conductor, and a pulley is rotatably connected to the outer surface of the slide frame, the pulley is slidably connected inside the spiral guide rail.

[0012] Furthermore, a first guide rail is provided on the outer circumference of the first rotating drum, a second guide rail is provided on the outer circumference of the second rotating drum, and a third guide rail is provided on the outer circumference of the third rotating drum.

[0013] Furthermore, the first guide rail includes a first helical groove and a first straight groove, the second guide rail includes a second helical groove and a second straight groove, and the third guide rail includes a third helical groove and a third straight groove.

[0014] Furthermore, an air tube is fixedly connected to the outer surface of the fixed rear ring, and an air ring is fixedly connected to one end of the air tube. The air ring is fixedly sleeved on the outer circumference of the outer ring. A push rod is slidably connected inside the air tube. A push block is fixedly connected to the end of the push rod away from the air tube. A pneumatic wheel is rotatably connected to the outer surface of the push block. The pneumatic wheel is slidably connected to the first guide rail, the second guide rail, and the third guide rail, respectively.

[0015] Furthermore, a sliding retaining strip is fixedly connected between the fixed rear ring and the air ring, and the push block is slidably connected to the sliding retaining strip.

[0016] The technical solution provided by this invention has the following advantages compared with the prior art: 1. This invention, by setting the interface temperature to rise, causes the pneumatic wheel to move along the sliding strip towards the fixed front ring. The pneumatic wheel drives the first rotating drum to rotate via the first guide rail. The first rotating drum drives the first ring body, the rear convex ring, the front convex ring, and the rotating ring to rotate. The rotating ring drives the push wheel and the sealing patches to move towards the inner ring along the axis of the telescopic cylinder via the push groove. The four sealing patches separate from the outer circumference of the wire connector, opening the gap between the wire connector and the inner ring. This releases the heat insulation effect of the four sealing patches on the interface, allowing the heat inside the interface to dissipate to the surrounding environment through conduction and convection, completing the initial heat dissipation of the interface, preventing damage to the conductor under long-term overheating, and improving the overall reliability of the equipment.

[0017] 2. In this invention, when the temperature of the interface section further increases, the pneumatic wheel continues to move along the sliding clip towards the fixed front ring. The pneumatic wheel drives the second rotating drum to rotate via the second guide rail. The second rotating drum drives the second ring body and the fan blade assembly to rotate. The rotating fan blade assembly accelerates the airflow speed inside the interface section. The airflow can quickly remove the heat inside the interface section, allowing the heat to be dissipated into the surrounding environment in a timely manner. This completes the further heat dissipation treatment of the interface section, prevents the conductor from being damaged under long-term overheating, and improves the overall reliability of the equipment.

[0018] 3. This invention, by setting the interface temperature to rise again, causes the pneumatic wheel to move along the sliding strip back towards the fixed front ring. The pneumatic wheel drives the third rotating drum to rotate via the third guide rail. The third rotating drum drives the third ring body and the spiral guide rail to rotate. The third ring body pushes the pulley and sliding frame along the slide rail towards the first ring body via the spiral guide rail. The sliding frame drives the pushing disc towards the first ring body. The pushing disc pushes the wire connector to separate from the conductor. The wire connector and the conductor lose electrical connection, and no more current and heat are generated between the conductor and the wire connector. The temperature inside the interface no longer rises, thus providing overload protection for the conductor and the wire connector, preventing damage to the conductor and the wire connector under long-term overheating, improving the overall reliability of the equipment, and reducing the maintenance cost of the equipment.

[0028] After fixing, a third rotating cylinder 6 is rotatably connected to the side of the ring 21 near the first rotating cylinder 4. The third rotating cylinder 6 is located between the first rotating cylinder 4 and the second rotating cylinder 5. A third ring body 61 is fixedly connected to the inner wall of the third rotating cylinder 6. A spiral guide rail 62 is provided on the inner wall of the third ring body 61.

[0029] A slide rail 7 is fixedly connected to the side of the fixed rear ring 21 near the fixed front ring 2. A slide frame 71 is slidably connected inside the slide rail 7.

The pneumatic wheel 84 is slidably connected to the first guide rail 91, the second guide rail 92 and the third guide rail 93 respectively.

[0033] A sliding retaining strip 85 is fixedly connected between the fixed rear ring 21 and the air ring 81, and the push block 83 is slidably connected to the sliding retaining strip 85.

[0034] Working principle: In practical applications, such as Figure 1 and Figure 2 As shown, the display control device is electrically connected to the wire connector 12 through the interface section 11 on the body 1. The body 1 is made of aluminum alloy and the surface of the body 1 is sprayed with anti-corrosion paint (such as epoxy resin or polyurethane). The body 1 adopts a closed chassis, retaining only the necessary interfaces (such as the interface section 11), and a rubber sealing ring is provided on the interface section 11 to prevent the interface from getting dusty. This makes the display control device have the characteristics of impact resistance, corrosion resistance, and dust prevention, ensuring stable operation of the device under harsh conditions, significantly improving its reliability, safety, and economy, while expanding the application scenarios and enhancing the user experience.

[0035] In practical applications, when the body 1 operates for extended periods or under high load, the interface section 11 needs to handle more current to support high-speed data transmission. This high current load causes more heat to be generated between the wire connector 12 and the conductor 23, such as... Figure 3 , Figure 8 and Figure 14 As shown, the four sealing patches 28 inside the inner ring 25 are attached to the outer circumferential surface of the wire connector 12 to achieve a dustproof seal for the interface 11. At the same time, due to the heat insulation effect of the four sealing patches 28, heat is difficult to dissipate to the surrounding environment quickly through conduction, convection and other means, which causes the internal temperature of the interface 11 to rise. The conductor 23 inside the fixed cylinder 22 is prone to damage under long-term overheating, reducing the overall reliability of the equipment and increasing the maintenance cost of the equipment.

[0036] To overcome the above difficulties, this application adopts the following technical solution: When the internal temperature of the interface section 11 rises, such as Figure 5 and Figure 6 As shown, the temperatures of the inner ring 25 and the outer ring 24 increase accordingly, as... Figure 4 and Figure 5As shown, the gas ring 81 and the gas tube 8 are filled with gas. Since the gas ring 81 is fixedly sleeved on the outer circumferential surface of the outer ring 24, heat is conducted to the interior of the gas ring 81 through the outer ring 24, thereby increasing the temperature of the gas inside the gas ring 81 and the gas tube 8. The gas inside the gas ring 81 and the gas tube 8 expands due to the heat, causing the expanded gas to push the two push rods 82 inside the gas tube 8 to move outward along the axis of the push rods 82. Under the limiting action of the sliding retaining strip 85, the two push rods 82 push the two push blocks 83 located at the top and bottom of the first rotating cylinder 4 to move towards the fixed front ring 2 along the sliding retaining strip 85. The two push blocks 83 drive the pneumatic wheels 84 on their outer surfaces to move towards the fixed front ring 2 along the sliding retaining strip 85. Figure 5 and Figure 6 As shown, during the process of the pusher block 83 driving the pneumatic wheel 84 to move along the sliding strip 85, the pneumatic wheel 84 is slidably connected to the first rotating drum 4 through the first spiral groove 911, and then combined with Figure 10 and Figure 12 It can be seen that the pneumatic wheel 84 is slidably connected to the third rotating cylinder 6 through the third straight groove 932, and the pneumatic wheel 84 is slidably connected to the second rotating cylinder 5 through the second straight groove 922. In this process, the moving pneumatic wheel 84 drives the first rotating cylinder 4 to rotate through the first guide rail 91. Under the limiting action of the third guide rail 93 and the second guide rail 92, the pneumatic wheel 84 moving in a straight line limits the third rotating cylinder 6 and the second rotating cylinder 5 (the second rotating cylinder 5 and the third rotating cylinder 6 cannot rotate around their own axis). The rotating first rotating cylinder 4 drives the first ring body 41 on its inner wall to rotate around the axis of the first ring body 41, such as... Figure 9 As shown, the rotating first ring 41 drives multiple telescopic shafts 42 on its outer surface to rotate around the axis of the first ring 41. The multiple telescopic shafts 42 drive the rear convex ring 43 at one end to rotate around the axis of the first ring 41. Under the "meshing" action of the rear convex ring 43 and the front convex ring 3, the rotating rear convex ring 43 drives the front convex ring 3 to rotate around the axis of the first ring 41. The front convex ring 3 drives the rotating ring 31 on its inner wall to rotate around the axis of the outer ring 24, as shown. Figure 7 and Figure 8 As shown, the rotating ring 31 drives the pushing groove 32 on its outer surface to rotate around the axis of the outer ring 24. Under the guidance of the telescopic cylinder 26 and the telescopic rod 27, the rotating ring 31 pushes the pushing wheel 33 and the sealing patch 28 along the axis of the telescopic cylinder 26 towards the inner ring 25 through the pushing groove 32 (the four sealing patches 28 separate from the outer circumferential surface of the wire connector 12). The four sealing patches 28 open the gap between the wire connector 12 and the inner ring 25, releasing the heat insulation effect of the four sealing patches 28 on the interface 11, so that the heat inside the interface 11 is dissipated to the surrounding environment through conduction, convection and other means, completing the initial heat dissipation of the interface 11, preventing the conductor 23 from being damaged under long-term overheating, and improving the overall reliability of the equipment.

[0037] As a further embodiment of the present invention, a spring is provided between the telescopic cylinder 26 and the telescopic rod 27, and a spring is provided between the telescopic shaft 42 and the first ring body 41. Under the elastic force of the spring, the spring provides a force to push the sealing patch 28 along the axis of the telescopic cylinder 26 toward the wire connector 12, and the spring provides a force to push the rear convex ring 43 along the axis of the telescopic shaft 42 toward the front convex ring 3. In the natural state, the rear convex ring 43 is in "engaged" contact with the front convex ring 3 under the elastic force of the spring, and the sealing patch 28 seals the interface 11 for dust prevention under the elastic force of the spring. Furthermore, the part of the sealing patch 28 that contacts the wire connector 12 is made of rubber material, which has excellent elasticity and resilience. The sealing patch 28 forms a tight seal between the wire connector 12 and the inner ring 25, providing good dustproof performance. Furthermore, the inner arc of the sealing patch 28 is chamfered. When the user inserts the wire connector 12 into the interface 11, the chamfer on the sealing patch 28 smoothly pushes the four sealing patches 28 a certain distance along the axis of the telescopic cylinder 26, facilitating easy insertion of the wire connector 12 into the interface 11. During the insertion process, the sealing patches 28 move along the axis of the telescopic cylinder 26, and the sealing patches 28 drive the rotating ring 31 to rotate via the push wheel 33 and push groove 32. The rotating ring 31 then drives the front protruding ring 3 to rotate. Figure 9 As shown, the rotation of the front protruding ring 3 at this time is in the same direction as the rotation of the front protruding ring 3 caused by the overheating of the interface 11. The front protruding ring 3 pushes the rear protruding ring 43 to move closer to the first ring body 41 along the axis of the telescopic shaft 42, so that the first ring body 41 does not rotate. The sealing patch 28 can also move along the axis of the telescopic cylinder 26. Therefore, the two opening methods of the sealing patch 28 (overheating opening of the interface 11 and insertion opening of the wire connector 12) are independent of each other and do not interfere with each other.

[0038] As a further embodiment of the present invention, when the four sealing patches 28 open the gap between the wire connector 12 and the inner ring 25, if the heat generated between the conductor 23 and the wire connector 12 remains too high, and the heat cannot be dissipated to the surrounding environment in time, as mentioned above, the temperature of the outer ring 24 continues to rise. The heat is conducted through the outer ring 24 to the interior of the gas ring 81, and the gas temperature inside the gas ring 81 and the gas tube 8 continues to rise. The gas inside the gas ring 81 and the gas tube 8 continues to expand. The expanded gas pushes the two push rods 82 inside the gas tube 8 to continue moving outward along the axis of the push rods 82. The push rods 82 continue to push the two push blocks 83 to move along the sliding strip 85 towards the fixed front ring 2. The two push blocks 83 drive the two pneumatic wheels 84 to move along the sliding strip 85 towards the fixed front ring 2. Figure 5 , Figure 10 and Figure 12As shown, the moving pneumatic wheel 84 is slidably connected to the first rotating drum 4 via the first straight groove 912, to the third rotating drum 6 via the third straight groove 932, and to the second rotating drum 5 via the second spiral groove 921. During this process, the moving pneumatic wheel 84 drives the second rotating drum 5 to rotate via the second guide rail 92. Under the limiting action of the first guide rail 91 and the third guide rail 93, the pneumatic wheel 84, moving in a straight line, limits the rotation of the first rotating drum 4 and the third rotating drum 6 (the first rotating drum 4 and the third rotating drum 6 cannot rotate around their own axes). Figure 13 and Figure 14 As shown, the rotating second drum 5 drives the second ring 51 on its inner wall to rotate around the axis of the second ring 51. The second ring 51 drives the fan blade assembly 52 on its inner wall to rotate around the axis of the second ring 51. The rotating fan blade assembly 52 accelerates the airflow speed inside the interface section 11. The airflow can quickly remove the heat inside the interface section 11, so that the heat can be dissipated to the surrounding environment in time, thereby completing the further heat dissipation treatment of the interface section 11, preventing the conductor 23 from being damaged under long-term overheating, and improving the overall reliability of the equipment.

[0039] As a further embodiment of the present invention, as the conductor 23 and the wire connector 12 continue to transmit data at high speed, the current flowing through the conductor 23 remains excessively large. The heat generated on the conductor 23 is far greater than the heat "blown away" by the fan blade assembly 52. ​​As mentioned above, the temperature of the outer ring 24 continues to rise. The heat is conducted through the outer ring 24 to the interior of the air ring 81, and the gas temperature inside the air ring 81 and the air pipe 8 continues to rise again. The gas inside the air ring 81 and the air pipe 8 expands again. The expanded gas pushes the two push rods 82 inside the air pipe 8 to move outward along the axis of the push rods 82. The push rods 82 continue to push the two push blocks 83 to move along the sliding clip 85 towards the fixed front ring 2. The two push blocks 83 drive the two pneumatic wheels 84 to move along the sliding clip 85 towards the fixed front ring 2. Figure 5 , Figure 10 and Figure 12 As shown, the moving pneumatic wheel 84 is slidably connected to the first rotating drum 4 via the first straight groove 912, and to the third rotating drum 6 via the third spiral groove 931. The moving pneumatic wheel 84 separates from the second rotating drum 5 via the opening of the second spiral groove 921 towards the first annular body 41. During this process, the moving pneumatic wheel 84 drives the third rotating drum 6 to rotate via the third guide rail 93. The first rotating drum 4 and the second rotating drum 5 cannot rotate around their own axes. Figure 13 , Figure 14 and Figure 15As shown, the rotating third drum 6 drives the third ring 61 on its inner wall to rotate around its axis. The third ring 61 drives the spiral guide rail 62 on its inner wall to rotate around its axis. Under the limiting action of the slide rail 7, the rotating third ring 61 pushes the pulley 73 and the sliding frame 71 along the slide rail 7 towards the first ring 41 through the spiral guide rail 62. The two sliding frames 71 drive the middle pushing disc 72 to move towards the first ring 41 along the axis of the pushing disc 72, so that the moving pushing disc 72 pushes the wire connector 12 sleeved on the outer surface of the conductor 23. When the conductor 23 is separated, the wire connector 12 loses its electrical connection with the conductor 23. The current and heat between the conductor 23 and the wire connector 12 cease to be generated, and the temperature inside the interface 11 stops rising. Furthermore, the heat inside the interface 11 is gradually dissipated to the surrounding environment through the gap between the wire connector 12 and the inner ring 25, and the temperature inside the interface 11 gradually decreases. This provides overload protection for the conductor 23 and the wire connector 12, preventing damage to the conductor 23 and the wire connector 12 under long-term overheating, improving the overall reliability of the equipment, and reducing the maintenance cost of the equipment.

[0040] As a further embodiment of the present invention, after the push disc 72 pushes the wire connector 12 to separate from the conductor 23, as the temperature inside the interface 11 gradually decreases, the temperature of the gas inside the air tube 8 and the air ring 81 gradually decreases, and the gas volume shrinks. Under the action of the external atmospheric pressure, the air outside the air tube 8 pushes the push rod 82 to move along the axis of the push rod 82 into the air tube 8. The push rod 82 drives the push block 83 and the pneumatic wheel 84 to move along the sliding clip 85 towards the fixed rear ring 21. The push block 83 and the pneumatic wheel 84 are reset.
