Description

Technical Field

[0001] This utility model belongs to the field of industrial control equipment technology, and in particular relates to a fully waterproof touch screen industrial control computer based on multi-structure sealing and conductive heat dissipation. Background Technology

[0002] In the current industrial control field, touchscreen industrial PCs are widely used in outdoor and humid indoor environments (such as charging piles, smart parcel lockers, medical equipment, etc.). Existing technologies mainly suffer from three types of design defects, which correspond one by one with the beneficial effects of this utility model: Some waterproofing issues: Most devices only provide a simple seal between the touchscreen and the front panel of the front frame, without designing a dedicated sealing structure for the connection seam between the front frame and the rear cover, wire harness interface, mounting holes, antenna interface, etc. This allows moisture to easily penetrate from these weak points, damaging the PCB board and electronic components, and shortening the lifespan of the device. Waterproofing and heat dissipation conflict: Some fully enclosed waterproof devices are not designed with heat conduction structure, so the heat generated by the PCB board cannot be dissipated, the internal temperature of the device rises, the chip efficiency decreases after long-term operation, and even the device may crash or shut down, failing to meet the requirements of continuous operation. Interface dispersion and sealing challenges: Existing equipment has scattered external interfaces without integrated wiring harnesses, making the operation cumbersome when connecting multiple external devices. Furthermore, each of the scattered interfaces needs to be sealed individually, which is difficult, prone to failure, and further increases the risk of moisture intrusion. Therefore, a fully waterproof touchscreen industrial control computer with conductive heat dissipation based on multi-structure sealing is needed to solve the above problems. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a fully waterproof touch screen industrial control computer based on multi-structure sealing and conductive heat dissipation to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A fully waterproof and heat-conducting touch screen industrial control computer based on multi-structure sealing includes a touch screen + display assembly, a plastic front frame, a sealing module, thermally conductive silicone, a back cover, an interface integration module, a PCB board, and a fixing block. The touch screen + display assembly and the plastic front frame are fixed and sealed by waterproof adhesive in the sealing module. The plastic front frame and the rear cover plate are detachably and sealed together by a waterproof O-ring in the sealing module. The PCB board is located inside the rear cover plate; The thermally conductive silicone is sandwiched between the PCB board and the back cover plate. The interface integration module is integrated into the back cover plate by a fixing block. The interface integration module is sealed by a silicone gasket in the sealing module. The rear cover plate is also equipped with a waterproof nut and a waterproof antenna in the sealing module, achieving full waterproofing and heat conduction.

[0005] A further technical solution is that the waterproof adhesive in the sealing module has a continuous ring structure with an adhesion strength of 6.12 kg / cm². 2 It has a temperature range of -40℃ to 150℃ and is UV resistant. The waterproof adhesive completely seals the gap between the touchscreen + display components and the plastic front frame, preventing moisture from entering through the front panel. It is also suitable for outdoor high and low temperature and ultraviolet radiation environments, ensuring long-term waterproof performance.

[0006] A further technical solution is that the waterproof O-ring in the sealing module is made of silicone with a wire diameter of 2.65mm and a hardness of 50 Shore A. The compression amount of the waterproof O-ring during the assembly of the plastic front frame and the rear cover is 0.4mm. The high elasticity of silicone and the specific amount of compression can completely fill the gap between the two. The Shore hardness of 50 ensures that the O-ring is not easily deformed and maintains its sealing performance for a long time, thus avoiding a decrease in waterproof rating.

[0007] A further technical solution is that the thermal conductivity of the thermally conductive silicone is... It is 2.5mm thick and fits perfectly against the PCB board and the back cover. High thermal conductivity allows for rapid heat transfer from the PCB board, seamless bonding reduces thermal resistance, and flexibility accommodates minor deformations of both components, preventing vibration-induced heat dissipation failure and ensuring stable equipment operating temperature.

[0008] A further technical solution is that the rear cover is made of aluminum plate, 1mm thick, with a thermal conductivity of [missing information]. The waterproof nuts in the sealing module are made of stainless steel and are riveted to the rear cover plate. The high thermal conductivity of the aluminum plate allows for rapid heat dissipation, while the stainless steel waterproof nuts, after being pressed and riveted, eliminate gaps in the mounting holes, prevent moisture intrusion, and prevent rust, thus extending the equipment's lifespan.

[0009] In a further technical solution, the silicone gasket in the sealing module is made of silicone with a thickness of 1mm and a hardness of 50 Shore A. The amount of compression on the silicone gasket during the assembly of the waterproof wire harness in the back cover and interface integration module is 0.3mm. The silicone gasket can fill the gaps between the waterproof wiring harness and the back cover plate. The specific amount of compression ensures a seal, and its flexibility adapts to the movement of the wiring harness, preventing vibration from causing the seal to fail.

[0010] In a further technical solution, the waterproof antenna in the sealing module is made of pure copper plated with gold and has a groove structure, with a waterproof ring fitted inside the groove. Pure copper with gold plating ensures stable signal transmission, and the grooved waterproof ring can seal the gaps in the antenna interface to prevent moisture from entering the signal interface without affecting the antenna's reception performance.

[0011] In a further technical solution, the waterproof harness in the interface integration module integrates multiple external interfaces, and the outer surface of the harness is wrapped with a waterproof layer. The centralized interface reduces the number of interfaces on the rear cover, simplifies sealing, and facilitates unified connection of external devices. The waterproof layer of the wiring harness and the silicone gasket form a double seal, further improving waterproofing. The overall waterproof rating of the machine reaches IP67.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model solves the problem of "partial waterproofing": through the multi-structure collaboration of the sealing module - waterproof adhesive seals the front panel, waterproof O-ring seals the front frame and rear cover, silicone gasket seals the wiring harness interface, waterproof nut seals the mounting hole, and waterproof antenna seals the signal interface, the whole machine is waterproof without dead angles, with a waterproof rating of IP67, completely blocking water vapor intrusion, avoiding damage to the PCB board and electronic components, and extending the service life of the equipment. This utility model solves the problem of "waterproofing and heat dissipation contradiction": by forming a heat conduction channel between thermally conductive silicone and aluminum plate back cover, the thermally conductive silicone quickly transfers heat from the PCB board, and the back cover efficiently dissipates heat, eliminating the need for heat dissipation holes (to avoid damaging the waterproofing), thus ensuring full waterproofing and preventing equipment from experiencing efficiency reduction or shutdown due to high temperatures. This utility model solves the problem of "dispersed interfaces and sealing difficulties": by concentrating the waterproof wire harness interfaces of the interface integration module, the operation process of external devices is simplified, while the number of interfaces on the back cover is reduced, and the difficulty of sealing is reduced; the waterproof layer of the wire harness and the silicone gasket form a double seal to prevent moisture intrusion at the interface, thereby improving the convenience and reliability of use.

[0013] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] like Figure 1-6 As shown, this utility model embodiment provides a fully waterproof and heat-conducting touch screen industrial control computer based on multi-structure sealing, including a touch screen + display assembly 1, a plastic front frame 2, a sealing module 3, thermally conductive silicone 4, a back cover 5, an interface integration module 6, a PCB board 7, and a fixing block 8. The touch screen + display assembly 1 and the plastic front frame 2 are fixed and sealed by the waterproof adhesive 31 in the sealing module 3. The plastic front frame 2 and the rear cover plate 5 are detachably and sealed together by the waterproof O-ring 32 in the sealing module 3; PCB board 7 is located inside the rear cover plate 5; Thermally conductive silicone 4 is sandwiched between PCB board 7 and back cover plate 5. Interface integration module 6 is integrated into back cover plate 5 through fixing block 8. Interface integration module 6 is sealed by silicone gasket 33 in sealing module 3. The rear cover plate 5 is also equipped with a waterproof nut 34 and a waterproof antenna 35 from the sealing module 3, achieving full waterproofing and heat conduction.

[0019] In this embodiment, the industrial control computer is based on "full waterproofing + conductive heat dissipation" as its core, and the various structures work together to achieve the function: the touch screen + display assembly 1 is the core of human-computer interaction, and is bonded to the plastic front frame 2 by the waterproof adhesive 31 of the sealing module 3. The entire circle of adhesive can completely seal the gaps in the front panel; the plastic front frame 2 serves as a structural support and is sealed to the rear cover 5 by a waterproof O-ring 32. The detachable design facilitates later maintenance; the PCB board 7 is the control core, and is symmetrically pressed against the inside of the rear cover 5 by the fixing block 8 to ensure that the thermally conductive silicone 4 fits without gaps; the waterproof wire harness 61 of the interface integration module 6 centralizes the interface and is sealed with silicone gaskets 33 to reduce waterproof dead spots; the waterproof nut 34 and the waterproof antenna 35 respectively solve the waterproofing problems of the mounting holes and signal interfaces of the rear cover 5, ultimately achieving the synergy of sealing and heat dissipation of the whole machine.

[0020] Specifically, the waterproof adhesive 31 in the sealing module 3 has a full-circle structure, an adhesion strength of 6.12 kg / cm², a temperature range of -40℃ to 150℃, and UV resistance.

[0021] In this embodiment, the waterproof adhesive 31 of the sealing module 3 adopts a full-circle design, which perfectly matches the edge shape of the touch screen + display assembly 1 and the plastic front frame 2. The high adhesion of 6.12kg / cm² can ensure that the two are tightly bonded for a long time, avoiding gaps caused by vibration during use. The temperature range of -40℃ to 150℃ can cope with the low temperature of winter and the high temperature of summer in outdoor environments. The UV resistance can prevent the adhesive from aging and the adhesion from being reduced due to sunlight exposure, ensuring the long-term waterproofness of the front panel from both material and structural aspects.

[0022] Specifically, the waterproof O-ring 32 in the sealing module 3 is made of silicone with a wire diameter of 2.65mm and a hardness of 50 Shore A. When the plastic front frame 2 and the rear cover plate 5 are assembled, the compression amount of the waterproof O-ring 32 is 0.4mm.

[0023] In this embodiment, the waterproof O-ring 32 of the sealing module 3 is made of high-elasticity silicone material. The combination of 2.65mm wire diameter and 0.4mm extrusion amount can completely fill the gap after the plastic front frame 2 and rear cover plate 5 are assembled to form an elastic sealing layer. The setting of 50 Shore hardness balances elasticity and wear resistance, avoiding O-ring deformation or wear due to long-term extrusion and sealing failure, and ensuring the waterproof reliability of the connection between the front frame and the rear cover plate.

[0024] Specifically, the thermal conductivity of thermally conductive silicone 4 is... It is 2.5mm thick and fits perfectly against the PCB board 7 and the back cover plate 5.

[0025] In this embodiment, the thermally conductive silicone 4 is the core carrier for heat transfer. The high thermal conductivity allows for rapid absorption of the heat generated by the PCB board 7 during operation. The 2.5mm thickness ensures that the silicone can fully adhere to the surfaces of the PCB board 7 and the back cover 5 (even if there are minor protrusions), eliminating thermal resistance caused by air gaps. At the same time, the silicone has good flexibility, so that when the equipment is vibrated and the PCB board 7 and the back cover 5 undergo minor relative displacement, they can still maintain a close fit, avoiding interruption of heat dissipation and ensuring that the temperature of the PCB board 7 remains stable within a safe range.

[0026] Specifically, the rear cover plate 5 is made of aluminum plate, 1mm thick, with a thermal conductivity of [missing information]. The waterproof nut 34 in the sealing module 3 is made of stainless steel and is riveted to the rear cover plate 5.

[0027] In this embodiment, the rear cover plate 5 is made of aluminum plate. The high thermal conductivity of the silicone 4 can quickly diffuse the heat transferred by the thermally conductive silicone to the outside air. The 1mm thickness ensures thermal conductivity while taking into account structural strength and preventing deformation of the back cover plate 5. The waterproof nut 34 of the sealing module 3 is made of stainless steel and is connected to the back cover plate 5 by a pressing process. During the pressing process, the nut and the cover plate form a tight fit, eliminating gaps in the mounting holes. This not only prevents moisture intrusion but also avoids rusting of the nut, which would make disassembly difficult later.

[0028] Specifically, the silicone gasket 33 in the sealing module 3 is made of silicone, with a thickness of 1mm and a hardness of 50 Shore A. When the rear cover plate 5 is assembled with the waterproof wire harness 61 in the interface integration module 6, the compression amount of the silicone gasket 33 is 0.3mm.

[0029] In this embodiment, the silicone gasket 33 of the sealing module 3 is 1mm thick and has a Shore hardness of 50. It can perfectly fill the gap between the rear cover plate 5 and the waterproof wire harness 61. The 0.3mm compression ensures that the gasket can fit tightly against the surfaces of both, forming an effective seal. The waterproofness and elasticity of the silicone material can accommodate the slight shaking of the waterproof wire harness 61 when it is connected to external equipment, avoiding gaps between the gasket and the wire harness and the cover plate due to shaking, and ensuring the waterproof stability of the interface.

[0030] Specifically, the waterproof antenna 35 in the sealing module 3 is made of pure copper plated with gold and has a groove structure with a waterproof ring fitted inside the groove.

[0031] In this embodiment, the waterproof antenna 35 of the sealing module 3 is made of pure copper plated with gold. The pure copper ensures signal transmission efficiency, and the gold plating layer can prevent antenna oxidation and extend signal transmission stability. The groove structure of the antenna is specially adapted to the waterproof ring. During installation, the waterproof ring is embedded in the groove and fits tightly with the antenna interface, completely sealing the gaps in the signal transmission channel. This does not affect the antenna's reception and transmission of signals, and also prevents moisture from entering the device from the antenna interface.

[0032] Specifically, the waterproof harness 61 in the interface integration module 6 integrates multiple external interfaces, and the outer surface of the harness is wrapped with a waterproof layer.

[0033] In this embodiment, the waterproof harness 61 of the interface integration module 6 centrally integrates the power interface, data interface, control interface, etc., reducing the traditionally scattered 5-8 interfaces to 1-2 integrated harness interfaces. This not only facilitates unified connection of external devices (eliminating the need to search for each interface individually), but also significantly reduces the difficulty of sealing the rear cover 5. The waterproof layer on the outer surface of the harness can directly block external moisture from contacting the interface. Combined with the silicone gasket 33 of the sealing module 3, it forms a dual protection of "weather harness self-waterproofing + installation part sealing", further improving the waterproofness of the interface. At the same time, the whole machine achieves an IP67 waterproof rating through the coordinated action of various sealing structures.

[0034] Working principle and usage process of this utility model: The workflow of this industrial control computer is divided into two parts: "assembly preparation" and "operation". The various components work together to achieve the functions. Assembly preparation process (ensuring proper sealing and heat dissipation); Step 1: Apply the waterproof adhesive 31 of the sealing module 3 to the edge of the touch screen + display assembly 1, align and bond it to the plastic front frame 2, and fix it with the high adhesion of the waterproof adhesive 31 to complete the front panel sealing. Step 2: Embed the waterproof O-ring 32 of the sealing module 3 into the sealing groove of the plastic front frame 2, ensuring that the O-ring fits the groove perfectly without any offset; Step 3: Lay thermally conductive silicone 4 on the inside of the back cover plate 5 to cover the installation area of ​​the PCB board 7, place the PCB board 7 on the silicone, and press the PCB board 7 symmetrically with the fixing block 8 to ensure that the silicone is tightly attached to the PCB board 7 and the back cover plate 5. Step 4: Place the silicone gasket 33 of the sealing module 3 at the wire harness interface of the rear cover plate 5, pass the waterproof wire harness 61 of the interface integration module 6 through the gasket and fix it, and squeeze the gasket to a deformation of 0.3mm; at the same time, press and rivet the waterproof nut 34 of the sealing module 3 into the mounting hole of the rear cover plate 5, and install the waterproof antenna 35 (with waterproof ring) into the antenna interface. Step 5: Align the plastic front frame 2 assembly from Step 2 with the rear cover plate 5 assembly from Step 4, and fix them with bolts to ensure that the waterproof O-ring 32 generates a compression amount of 0.4mm, and complete the assembly of the whole machine. Operational workflow (waterproofing, heat dissipation, interface coordination); When the equipment is powered on: Waterproof function: When external moisture comes into contact with the device, the waterproof backing 31 prevents it from entering through the gap between the touch screen + display assembly 1 and the plastic front frame 2; the waterproof O-ring 32 seals the connection seam between the plastic front frame 2 and the rear cover plate 5; the silicone gasket 33, waterproof nut 34, and waterproof antenna 35 respectively seal the wire harness interface, mounting hole, and signal interface to achieve IP67 waterproof rating for the whole device. Heat dissipation function: The heat generated by the PCB board 7 during operation is quickly transferred to the back cover plate 5 through the thermal conductive silicone 4. The aluminum plate back cover plate 5 dissipates the heat to the outside, avoids the accumulation of internal heat, and ensures the temperature of the PCB board 7 is stable. Interface Function: External devices are centrally connected via the waterproof wiring harness 61 of the interface integration module 6, which is convenient to operate. The waterproof layer of the wiring harness and the silicone gasket 33 prevent moisture intrusion during the connection process, ensuring stable operation of the equipment.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
