Description

Technical Field

[0001] This invention relates to the field of communication module installation technology, specifically to a communication module fixing device for high-temperature environments. Background Technology

[0002] Communication modules are core components in industrial control and IoT data transmission systems. In some cases, they need to be installed in high-temperature cabinets, outdoor equipment boxes, and other environments. Their ease of installation and heat dissipation reliability directly affect the equipment deployment efficiency and service life.

[0003] Most existing communication modules are connected to the mounting base using screws. Disassembly and assembly within the confined space of the cabinet requires screwdrivers and other tools, limiting operational space and reducing the efficiency of on-site deployment and subsequent maintenance and replacement. Some snap-on quick-release structures require holding down the unlocking mechanism to remove the module, making one-handed operation difficult and hindering rapid maintenance in confined spaces.

[0004] In terms of heat dissipation, conventional communication modules mostly adopt a fixed opening heat dissipation structure. Long-term open heat dissipation windows can easily lead to dust and moisture entering the module, accelerating component aging and affecting the service life of the equipment. Some temperature control heat dissipation structures rely on electronic sensors and electric drive mechanisms to open and close, resulting in a complex overall structure. In industrial environments with high temperatures and strong electromagnetic interference, the failure rate is relatively high, the reliability is insufficient, and it is difficult to meet the stable operation requirements under long-term high-temperature conditions.

[0005] Therefore, there is a need to provide a communication module fixing device for high-temperature environments, which aims to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a communication module fixing device for high-temperature environments.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a communication module fixing device for high-temperature environments, comprising a mounting base and a communication module housing, wherein the communication module housing is disposed on one side of the mounting base, and the outer wall of the communication module housing is provided with a main exhaust window and a secondary exhaust window;

[0008] A rectangular frame is fixedly connected to the outer wall of the communication module housing. An exhaust fin is slidably connected to the inner wall of the rectangular frame. A heat transfer copper sheet is fixedly connected to the outer wall of the communication module housing. Memory springs are symmetrically fixedly connected to the heat transfer copper sheet. The ends of the two memory springs away from the heat transfer copper sheet are fixedly connected to the exhaust fin.

[0009] Preferably, a heat insulation block is provided between the rectangular frame and the heat transfer copper sheet.

[0010] Preferably, the mounting base and the communication module housing are symmetrically provided with fixing components. The fixing components include positioning blocks, which are fixedly connected to the communication module housing. The positioning blocks are symmetrically provided with second limiting grooves inside, and trapezoidal limiting rods are slidably connected inside the two second limiting grooves.

[0011] Preferably, a second return spring is sleeved on the outer wall of the trapezoidal limiting rod, one end of the second return spring is fixedly connected to the positioning block, and the other end of the second return spring away from the positioning block is fixedly connected to the trapezoidal limiting rod.

[0012] Preferably, the fixing component includes a first limiting slide groove, which is formed inside the mounting base. A pressing column is slidably connected inside the first limiting slide groove, and a limiting plate is sleeved on the outer wall of the pressing column.

[0013] Preferably, the fixing component includes a first return spring, which is sleeved on the outside of the pressing post, one end of the first return spring is fixedly connected to the limiting plate, and the other end of the first return spring away from the limiting plate is fixedly connected to the mounting base.

[0014] Preferably, an arc-shaped limiting piece is fixedly connected to the end of the pressing column away from the limiting plate, a fixing ring is fixedly connected to the side of the pressing column near the arc-shaped limiting piece, an unlocking piece is provided between the arc-shaped limiting piece and the fixing ring, and the unlocking piece is slidably connected to the pressing column.

[0015] Preferably, the secondary exhaust window is positioned on the movement path of the exhaust vane.

[0016] Preferably, a heat sink is provided inside the communication module housing, and the heat transfer copper sheet is connected to the heat sink inside the communication module housing.

[0017] Preferably, the limiting disk is slidably connected inside the first limiting groove.

[0018] The present invention provides a communication module fixing device for high-temperature environments. Compared with the prior art, the advantages of the present invention are:

[0019] By incorporating a temperature-controlled adaptive auxiliary heat dissipation structure driven by a memory spring, the secondary exhaust window can automatically open and close based on the module's internal temperature. At normal temperatures, the secondary exhaust window closes to prevent dust and moisture from entering the module, ensuring the cleanliness of the components. At high temperatures, the secondary exhaust window opens to enhance airflow and heat dissipation. The entire structure requires no additional electronic control components or power supply, is simple in design, has a low failure rate, and can improve heat dissipation capacity under high-temperature environments while providing dust protection, ensuring the stability of the communication module's operation.

[0020] By adopting a plug-in quick-release locking structure, axial locking can be automatically completed with a single push during installation, eliminating the need for screws and additional tools. This reduces the difficulty of installation operations in confined spaces and improves the efficiency of on-site deployment, maintenance, and replacement of communication modules. The trapezoidal limit rod and arc-shaped limit piece use a direct-face engagement limiting method, ensuring reliable axial locking. It is not easily loosened by equipment vibration or external pulling forces, making it suitable for use in complex industrial conditions.

[0021] With its matching single-press unlocking mechanism, pressing down and releasing automatically unlocks the device, eliminating the need to continuously press the button to remove the module. This simplifies operation and further reduces the difficulty of disassembly in confined spaces. The entire locking and unlocking mechanism is purely mechanical, requiring no electronic components, ensuring high operational stability and adaptability to high-temperature and high-electromagnetic-interference environments.

[0022] Both the fixing components and the heat dissipation components are integrated into the outer wall of the communication module housing, which does not occupy the electrical installation space inside the module and will not interfere with the layout of internal components. The structure is compact and can be adapted to the modification and use of conventional-sized communication modules. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 for explaining the invention and are not intended to limit the invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0037] Implementation, for example Figures 1 to 8 As shown, an embodiment of the present invention provides a communication module fixing device for high-temperature environments, including a mounting base 11 and a communication module housing 12. The communication module housing 12 is disposed on one side of the mounting base 11. Fixing components are symmetrically arranged on the mounting base 11 and the communication module housing 12 to ensure balanced installation force. The outer wall of the communication module housing 12 is provided with a main exhaust window and a secondary exhaust window 31. The main exhaust window is a conventional heat dissipation channel, and the secondary exhaust window 31 is an auxiliary heat dissipation channel with temperature-controlled opening and closing. Heat dissipation components are provided on the outer wall of the communication module housing 12.

[0038] The fixing component includes a positioning block 28, which is fixedly connected to the communication module housing 12. The positioning block 28 has symmetrically formed second limiting grooves 29 inside, and trapezoidal limiting rods 210 are slidably connected inside each of the two second limiting grooves 29. A second return spring 211 is sleeved on the outer wall of the trapezoidal limiting rod 210. One end of the second return spring 211 is fixedly connected to the positioning block 28, and the other end of the second return spring 211 away from the positioning block 28 is fixedly connected to the trapezoidal limiting rod 210. The trapezoidal limiting rod 210 has a guide slope on one side facing the installation entrance and a limiting straight surface on the other side. The guide slope is used to automatically retract under the pressure of the arc-shaped limiting piece 25 during installation, achieving operation-free insertion. The limiting straight surface is used to withstand axial tension after engagement, forming a rigid limit and ensuring locking reliability.

[0039] The fixing assembly includes a first limiting groove 21, which is formed inside the mounting base 11. A pressing post 22 is slidably connected inside the first limiting groove 21. A limiting plate 23 is sleeved on the outer wall of the pressing post 22 and slidably connected inside the first limiting groove 21 to limit the sliding stroke and circumferential deflection of the pressing post 22. The fixing assembly also includes a first return spring 24, which is sleeved on the outer side of the pressing post 22. One end of the first return spring 24 is fixedly connected to the limiting plate 23, and the other end of the first return spring 24 away from the limiting plate 23 is fixedly connected to the mounting base 11, providing a reset driving force for the pressing post 22.

[0040] An arc-shaped limiting piece 25 is fixedly connected to the end of the pressing post 22 away from the limiting plate 23. A fixing ring 26 is fixedly connected to the side of the pressing post 22 near the arc-shaped limiting piece 25. An unlocking piece 27 is provided between the arc-shaped limiting piece 25 and the fixing ring 26, and the unlocking piece 27 is slidably connected to the pressing post 22. The opposite end faces of the unlocking piece 27 and the arc-shaped limiting piece 25 are both set as adaptive bevels. After the two are fitted together, they can be spliced ​​to form a continuous and complete arc surface. This structure is the core of realizing automatic unlocking with a single press: after pressing to the position, the unlocking piece 27 passes over the trapezoidal limiting rod 210 and is locked. During the retraction process, the two splice to form an arc surface, which can squeeze and compress the trapezoidal limiting rod 210 back. The release can be completed without continuously pressing the pressing post 22, simplifying the disassembly operation.

[0041] A rectangular frame 32 is fixedly connected to the outer wall of the communication module housing 12. An exhaust fin 33 is slidably connected to the inner wall of the rectangular frame 32, providing vertical sliding guidance for the exhaust fin 33. A heat transfer copper plate 34 is fixedly connected to the outer wall of the communication module housing 12. A heat sink is installed inside the communication module housing 12, and the heat transfer copper plate 34 is connected to the heat sink inside the communication module housing 12, allowing heat generated by the internal components of the module to be quickly dissipated to the outer wall structure. Memory springs 36 are symmetrically fixedly connected to the heat transfer copper plate 34, with the ends of both memory springs 36 away from the heat transfer copper plate 34 fixedly connected to the exhaust fin 33. The memory springs 36 are made of nickel-titanium memory alloy and can undergo directional expansion and contraction deformation at a set temperature threshold, providing a purely temperature-controlled driving force for the sliding of the exhaust fin 33 without the need for additional electronic control components.

[0042] A heat insulation block 35 is provided between the rectangular frame 32 and the heat transfer copper plate 34. The heat insulation block 35 is made of a low thermal conductivity material to block heat conduction to the rectangular frame 32, preventing the rectangular frame 32 from expanding due to heat and affecting the sliding accuracy of the exhaust fin 33. At the same time, it reduces the interference of the external ambient temperature on the memory spring 36, ensuring the accuracy of temperature control triggering. The auxiliary exhaust window 31 is set on the movement path of the exhaust fin 33. The exhaust fin 33 is provided with a corresponding hollow through slot. When the through slot is aligned with the auxiliary exhaust window 31, auxiliary heat dissipation can be opened. When misaligned, it can be closed to prevent dust, realizing the automatic opening and closing of the heat dissipation channel.

[0043] When installing the communication module housing 12, align the groove of the positioning block 28 on the side of the communication module housing 12 with the arc-shaped limiting piece 25 on the side of the mounting base 11, and push the communication module housing 12 axially so that the positioning block 28 moves into the arc-shaped limiting piece 25. During the insertion process, the guide slope of the trapezoidal limiting rod 210 first contacts the outer edge of the arc-shaped limiting piece 25, and retracts inward along the second limiting groove 29 under radial extrusion force, simultaneously compressing the second return spring 211; when the end face of the positioning block 28 abuts against the side wall of the mounting base 11, the trapezoidal limiting rod 210 passes over the arc-shaped limiting piece 25, the extrusion force disappears, and the second return spring 211 pushes the trapezoidal limiting rod 210 outward, with the limiting straight surface abutting against the inner end face of the arc-shaped limiting piece 25, forming an axial locking, and the installation can be completed in one step.

[0044] When disassembling the communication module housing 12, pressing the pressing post 22 inward causes the limiting plate 23 to slide inward along the first limiting groove 21, stretching the first return spring 24. The arc-shaped limiting piece 25 and the unlocking piece 27 move inward synchronously. The end face of the unlocking piece 27 first contacts the trapezoidal limiting rod 210, pushing it to retract inward and compress the second return spring 211. When pressed to the end of the stroke, the unlocking piece 27 completely passes the trapezoidal limiting rod 210, and the second return spring 211 pushes the trapezoidal limiting rod 210 to extend again, abutting against the outer end face of the unlocking piece 27 to form a locking position.

[0045] After releasing the pressing post 22, the first reset spring 24 retracts and resets, pulling the pressing post 22 and the arc-shaped limiting piece 25 outward. After the end face of the arc-shaped limiting piece 25 is in contact with the unlocking piece 27, the two are spliced ​​into a continuous arc surface. When moving back, the trapezoidal limiting rod 210 is retracted inward again under the radial force of the arc surface. The arc-shaped limiting piece 25 and the unlocking piece 27 are disengaged from the groove of the positioning block 28, releasing the locking limit. The communication module housing 12 can then be removed. Unlocking can be completed with a single press, without the need for continuous force, making it suitable for maintenance work in confined spaces.

[0046] Under normal operating conditions, the memory spring 36 is in an extended state, pushing the exhaust fin 33 to maintain its initial position. The solid area of ​​the exhaust fin 33 is misaligned with the secondary exhaust window 31, closing the secondary exhaust window and preventing external dust and moisture from entering the module, ensuring the cleanliness of the components. When the module is in a high-temperature environment and internal heat dissipation is insufficient, the temperature rises to the deformation threshold of the memory spring 36. The memory spring 36 contracts due to heat, pulling the exhaust fin 33 to slide along the rectangular frame 32. The hollow slot aligns with the secondary exhaust window 31, opening the auxiliary heat dissipation channel, increasing the airflow area, enhancing heat dissipation, and preventing excessive internal temperature accumulation. After the temperature drops below the threshold, the memory spring 36 automatically returns to its extended state, pushing the exhaust fin 33 back to its original position, and the secondary exhaust window automatically closes, achieving temperature-controlled adaptive opening and closing.

[0047] Based on the above embodiments, the following is the complete working process and working principle of the above embodiments:

[0048] Quick-release fixing steps:

[0049] When installing the communication module housing 12, first align the groove of the positioning block 28 on the side of the communication module housing 12 with the arc-shaped limiting piece 25 on the side of the mounting base 11, and push the communication module housing 12 axially so that the positioning block 28 moves into the arc-shaped limiting piece 25.

[0050] During the insertion process, the inclined surface of the trapezoidal limiting rod 210 inside the positioning block 28 first contacts the outer edge of the arc-shaped limiting piece 25. After being subjected to radial extrusion force, it retracts inward along the second limiting groove 29, simultaneously compressing the second reset spring 211.

[0051] When the positioning block 28 is fully inserted and its end face abuts against the side wall of the mounting base 11, the trapezoidal limiting rod 210 passes over the arc-shaped limiting piece 25, the radial compressive force disappears, the second return spring 211 elastically extends, pushing the trapezoidal limiting rod 210 outward along the second limiting groove 29, and the straight end of the trapezoidal limiting rod 210 abuts against the inner end face of the arc-shaped limiting piece 25, forming an axial locking limit, locking and fixing the positioning block 28 and the communication module housing 12 on the mounting base 11. Installation can be completed in one step without tools.

[0052] Press to unlock and disassemble:

[0053] When the communication module housing 12 needs to be disassembled, press the pressing post 22 on the side of the mounting base 11 inward. The pressing post 22 drives the limiting plate 23 to slide inward along the first limiting slide groove 21, and simultaneously stretches the first return spring 24. The arc-shaped limiting piece 25 at the end of the pressing post 22 and the unlocking piece 27 move inward in sync. The end face of the unlocking piece 27 first contacts the trapezoidal limiting rod 210, pushing the trapezoidal limiting rod 210 to retract inward along the second limiting slide groove 29 and compress the second return spring 211.

[0054] When the pressing column 22 is pressed to the end of its stroke, the unlocking piece 27 completely passes the trapezoidal limit rod 210, and the second return spring 211 pushes the trapezoidal limit rod 210 outward again. The end of the trapezoidal limit rod 210 abuts against the outer end face of the unlocking piece 27, so that the unlocking piece 27 disengages from the fixing ring 26.

[0055] At this point, releasing the pressing post 22 causes the first return spring 24 to retract and reset, pulling the limiting plate 23 and the pressing post 22 outwards. The arc-shaped limiting piece 25 moves outwards synchronously with the pressing post 22 until the end face of the arc-shaped limiting piece 25 fits against the end face of the unlocking piece 27, forming a continuous arc surface. During the continued retraction, the trapezoidal limiting rod 210, under the radial force of the arc surface, compresses the second return spring 211 again, causing it to retract inwards. The arc-shaped limiting piece 25 and the unlocking piece 27 are then disengaged from the groove of the positioning block 28, releasing the axial locking limit. The communication module housing 12 can then be directly removed, completing the disassembly. This unlocking structure features a design that automatically releases with a single press, eliminating the need to continuously press the pressing post to remove the module. The operation is simple and suitable for maintenance work in confined spaces.

[0056] Temperature-controlled adaptive assisted heat dissipation steps:

[0057] The heat generated inside the communication module housing 12 is conducted to the heat transfer copper plate 34 through the internal heat sink, and the heat transfer copper plate 34 synchronously transfers the temperature to the memory spring 36. Under normal operating conditions, the memory spring 36 is in its extended state, pushing the exhaust plate 33 to remain in its initial position along the rectangular frame 32. The solid area of ​​the exhaust plate 33 is offset from the secondary exhaust window 31, and the secondary exhaust window is in the closed state, which can prevent external dust and moisture from entering the module and ensure the cleanliness of the internal components.

[0058] When the communication module is in a high-temperature environment and the internal heat dissipation is insufficient, the temperature rises to the deformation threshold of the memory spring 36. The memory spring 36 is heated and shrinks, pulling the exhaust plate 33 to slide along the inner wall of the rectangular frame 32. This causes the hollow slot of the exhaust plate 33 to gradually align and overlap with the secondary exhaust window 31, opening the auxiliary heat dissipation channel, increasing the air circulation area between the inside of the module and the outside, improving heat dissipation efficiency, and avoiding excessive internal temperature accumulation that could affect the stability of the communication module's operation.

[0059] When the internal temperature drops below the threshold, the memory spring 36 temperature decreases synchronously, automatically returning to its extended state. This pushes the exhaust fin 33 to slide back along the rectangular frame 32, repositioning it and automatically closing the auxiliary heat dissipation channel. A heat insulation block 35 is installed between the rectangular frame 32 and the heat transfer copper plate 34 to block heat conduction to the rectangular frame 32, preventing structural thermal expansion from affecting the smoothness of the exhaust fin 33's sliding. This also ensures the temperature triggering accuracy of the memory spring 36 and reduces environmental temperature interference.

[0060] The entire fixing structure employs a purely mechanical locking mechanism, requiring no screws or additional tools. Installation and disassembly are both single-step operations, improving on-site deployment and maintenance efficiency. The bidirectional straight-face locking structure provides reliable axial limiting and is not easily loosened by vibration or external pulling, making it suitable for complex industrial applications with high temperatures and high vibrations. The temperature-controlled auxiliary heat dissipation structure requires no additional electronic components or power supply, relying solely on the temperature characteristics of the shape memory alloy to automatically open and close the heat dissipation channels. This results in low energy consumption and a low failure rate. It can dynamically adjust the heat dissipation area according to the actual heat generation status, balancing dust protection and high-temperature heat dissipation requirements, thus improving the operational stability and lifespan of the communication module in high-temperature environments.
