Description

Technical Field

[0001] This invention relates to the field of water meter water usage data acquisition and long-distance transmission, and is mainly an Internet of Things (IoT) water meter remote transmission module. Background Technology

[0002] With the increasing market demand for water usage big data, water usage data collection using non-magnetic technology and long-distance data transmission using the dominant NB-IoT Internet of Things technology have become the mainstream in the water meter industry. Consequently, the contradiction between the structural requirements of these water meters, which carry numerous electronic components and batteries, and the harsh actual installation conditions has become increasingly prominent. Currently, solutions for waterproofing, moisture-proofing, and mildew-proofing electronic components generally employ multiple measures, such as spraying conformal coating on circuit boards and overall potting, or immersing electronic components in potting and adding mechanical sealing. These sealing solutions involve numerous processes, are inefficient, and have extremely high requirements for workpiece manufacturing and assembly, making it difficult to further improve the yield rate. Furthermore, in potting sealing solutions, poor glue flow often results in some electronic components not being fully submerged and becoming damp; or the glue reflowing in the high-temperature curing oven causes component displacement and glue creep at mating parts, thus affecting the final assembly and sealing effect. Summary of the Invention

[0003] The purpose of this invention is to overcome the problems of complex sealing and high requirements for workpieces and processes in the above-mentioned water meter remote transmission modules, and to provide an IoT water meter remote transmission module with simple structure and easy and fast potting.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows:

[0005] An IoT water meter remote transmission module includes a module box, a transparent cover, and a module cover. The module box has a battery compartment for holding batteries, and the battery compartment has a square-round compartment that mates with a wire threading plug. The battery compartment has openings at both ends to facilitate online battery replacement in confined spaces. The module box has positioning transparent covers and BOSS posts for fixing the module cover. The transparent cover has a smooth cylindrical hole that mates with a sealing plug. The lower end of the smooth cylindrical hole has a glue-filling port, and the inner wall of the smooth cylindrical hole has a limiting platform with an exhaust hole. The vent on the transparent cover is higher than the periphery of the assembled module box, ensuring that air in the internal cavity can be discharged in time during potting and heat curing, and that the glue flows smoothly. The potting port and vent on the transparent cover have the same structural design, which allows for waterproof and moisture-proof sealing of the two cavities with a single sealing plug. The outer wall of the transparent box is provided with an infrared setting window and an antenna protrusion for placing the antenna. The module cover is provided with an outer protrusion that accommodates the antenna protrusion and an infrared groove that matches the infrared setting window. The module box and the module cover are connected and fixed. The transparent cover is embedded between the module box and the module cover. The method of using this invention is to first pass the battery wire through the battery wire through hole and then solder it to the main circuit board. Then, pass the battery wire through the square groove in the square and round compartment and insert the square platform into the square groove so that the wire plug fits tightly and aligns with the square and round compartment. Next, align the planar support holes and screw fastening holes with the top post and hole post, respectively, and fasten the main circuit board to the module box. Insert the acquisition circuit board into the recessed compartment and connect the two circuit boards. Align the two post holes with the BOSS post guide and install the transparent cover inside the module box until the surrounding plane is flush with the first limiting surface. During glue application, place the flat rib into the tooling fixture, and insert the glue nozzle of the glue applicator into the glue inlet until the glue chamber is full of glue. At this point, the lower end of the glue inlet is immersed in the glue. After the glue has cured, fit the arc-shaped sealing rib into the smooth round... Press the sealing plug into the post hole until the second limiting surface is flush with the limiting platform. At this point, the sealing plug blocks both the glue inlet and the vent. Align the perimeter and fit the infrared setting window and antenna protrusion into the infrared slot and outer protrusion respectively until the protrusion is snapped into the slot. Finally, use screws to pass through the BOSS post and fasten it to the long stud. Place the battery into the battery compartment, connect the battery wiring, install other mechanical seals, and screw the battery compartment sealing cover onto the battery compartment sealing cover thread, thus forming the complete IoT water meter remote transmission module.

[0006] As a preferred option, the outer wall of the module box is provided with a recessed compartment for placing the acquisition plate, and a protruding buckle above the recessed compartment for locking the module cover. The inner wall of the module box is provided with a locking platform for restricting the transparent cover. The multi-buckle design reduces the use of screws, making production more efficient.

[0007] Preferably, the module box is provided with a fastening module positioning hole, and the module box is provided with a first limiting surface for placing the transparent cover. The first limiting surface is provided with a screw platform hole for fastening the transparent cover. The module box positioning hole design with sufficient depth can not only submerge the screw tail structure, but also leave space for assembling the anti-tamper lead seal cover.

[0008] Preferably, the module box has a periphery forming a potting cavity, and the lower end of the module box has a flat rib for easy placement of the remote transmission module. The square and round compartments have reserved threads for the battery compartment sealing cover. The reserved threads for the battery compartment sealing cover, together with other parts, form a mechanical seal to ensure that the battery can be replaced at any time. The module box has a blind hole for the communication line. The reserved blind hole for the communication line can facilitate the conversion from wireless to wired without the need for a separate mold. The cross-section of the blind hole for the communication line is a combination of circular and rectangular. The module box has a double-sided flat rib design to facilitate the stable placement of the remote transmission module on the potting and assembly line.

[0009] Preferably, the module cover has a perimeter to prevent it from slipping and to cover the assembly seam. The lower end of the perimeter has several fastening slots that match the protrusions of the module box. It also has long studs for fastening to the module box and a large platform for printing or laser engraving. The multi-snap design reduces the use of screws, making production more efficient. The large platform design of the module cover can accommodate more printed or laser engraved water meter information.

[0010] Preferably, the battery compartment is provided with post holes for positioning and securing the main circuit board and top posts for supporting the main circuit board.

[0011] Preferably, the sealing plug is a soft rubber body with multiple arc-shaped sealing ribs that deform and seal, and a second limiting surface that works with the transparent cover to enhance the sealing performance of the device. The transparent cover is made of transparent material, which not only ensures the infrared communication requirements, but also allows for observation of the dispensing process and the cured adhesive at any time.

[0012] Preferably, the main circuit board is provided with several screw fastening holes and post support holes that cooperate with the module box. The planar support holes and screw fastening holes are aligned with the top post and the post respectively, so as to fasten the main circuit board to the module box.

[0013] Preferably, the wire threading plug is an elastic body. The wire threading plug has a battery wiring through hole and a square platform to prevent it from rotating freely. The square platform is inserted into the square groove so that the wire threading plug is tightly fitted and aligned with the square and round compartment, preventing the wire threading plug from rotating freely and affecting its use. The square locking position of the wire threading plug and the module box effectively prevents the two battery wires from rotating and getting tangled, resulting in short circuits or open circuits.

[0014] Preferably, the glue filling chamber is a cavity formed by the module box and the transparent cover. The glue filling chamber can accommodate glue that is poured separately or that overflows after being poured from inside the module box. There is no need to worry that the glue will climb to the mating surface due to capillary effect and cure, which will cause difficulties in installing the transparent cover or failure of the seal. It also prevents the transparent cover from being deformed or displaced by stress during the heat curing stage.

[0015] The beneficial effects of this invention are: 1. The transparent cover and module box are first fitted together to form a closed cavity before the entire assembly is filled with adhesive, preventing adhesive overflow. This eliminates concerns about adhesive climbing to the mating surface due to capillary effect and curing, which could lead to installation difficulties or sealing failure of the transparent cover. It also prevents the adhesive from deforming or shifting due to stress during the heat curing stage. 2. The vent on the transparent cover is higher than the periphery of the assembled module box, ensuring timely air removal from the internal cavity during adhesive filling and heat curing, and smooth adhesive flow. 3. The adhesive filling port and vent on the transparent cover have the same structural design, allowing for waterproof and moisture-proof sealing of two cavities with a single sealing plug. 4. The transparent cover and module box use a small-circumference planar fit and are fixed with clips or screws, eliminating large gaps and preventing adhesive leakage along the battery wiring due to air pressure imbalance. 5. The transparent cover is made of transparent material, ensuring infrared communication requirements while allowing for observation of the adhesive filling process and the cured adhesive condition. 6. The multi-clip design reduces the use of screws, making production more efficient. 7. The wire guide plug and square locking mechanism of the module box effectively prevent short circuits or open circuits caused by the rotation and tangling of the two battery wires. 8. The pre-reserved blind hole for communication wires facilitates the conversion from wireless to wired communication without the need for additional molds. 9. The double-sided flat rib design of the module box allows for stable placement of the remote transmission module on the potting and assembly line. 10. The pre-reserved threaded sealing cover for the battery compartment, along with other components, forms a mechanical seal, ensuring easy battery replacement. 11. Openings at both ends of the battery compartment facilitate online battery replacement even in confined spaces. 12. The large platform design of the module cover allows for more printed or laser-engraved water meter information. 13. The sufficiently deep positioning hole design of the module box allows for the submersion of the screw tail structure and provides space for the assembly of the tamper-proof lead-sealed cover.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1:

[0025] An IoT water meter remote transmission module includes a module box 1, a transparent cover 2, and a module cover 4. The module box 1 has a battery compartment 1-1 for holding batteries. The battery compartment 1-1 has a square-round compartment 1-2 that mates with a wire threading plug 6. The battery compartment 1-1 has openings at both ends to facilitate online battery replacement in a confined space. The module box 1 has a positioning transparent cover 2 and a BOSS post 1-3 for fixing the module cover 4. The transparent cover 2 has a smooth cylindrical hole 2-1 that mates with a sealing plug 3. The lower end of the smooth cylindrical hole 2-1 has a glue-filling port 2-3. The inner wall of the smooth cylindrical hole 2-1 has a limiting platform 2-2, and the limiting platform 2-2 has an exhaust hole 2-4. The vent 2-4 on the transparent cover 2 is higher than the periphery of the assembled module box 1, thus ensuring that the air in the internal cavity can be discharged in time during glue pouring and heat curing, and that the glue flows smoothly. The glue pouring port 2-3 of the transparent cover 2 has the same structural design as the vent 2-4, which makes it easy to complete the waterproof and moisture-proof sealing of the two holes with one action of a sealing plug 3. The outer wall of the transparent cover 2 is provided with an infrared setting window 2-7 and an antenna protrusion 2-8 for placing the antenna. The module cover 4 is provided with an outer protrusion 4-3 that accommodates the antenna protrusion 2-8 and an infrared groove 4-4 that matches the infrared setting window 2-7. The module box 1 and the module cover 4 are connected and fixed, and the transparent cover 2 is embedded between the module box 1 and the module cover 4.

[0026] Method of using the present invention: as follows Figure 1 and Figure 2As shown, first, the battery wire is passed through the battery wire through hole 6-1 and soldered onto the main circuit board 5. Then, the battery wire is passed through the square groove in the square and round compartment 1-2, and the square platform 6-2 is inserted into the square groove, so that the wire plug 6 and the square and round compartment 1-2 are tightly fitted and aligned. In the next step, the planar support hole 5-1 and the screw fastening hole 5-2 are aligned with the top post 1-11 and the hole post 1-10, respectively, and the main circuit board 5 is fastened to the module box 1. The acquisition circuit board is installed into the recessed compartment 1-5 and the two circuit boards are connected. The two post holes 2-9 are aligned with the BOSS post 1-3 to guide the installation of the transparent cover 2 into the module box 1 until the peripheral plane 2-10 is close to the first limiting surface 1-8. At this time, the transparent cover 2 is restricted by the positioning platform 1-6 and cannot be removed at will. The transparent cover 2 and the module box 1 are closed to form an internal potting space and an external potting compartment 7. Before applying a low-viscosity, high-flowability adhesive, first tighten a screw through screw hole 2-5 onto screw platform hole 1-9 to ensure capillary effect during dispensing. During dispensing, place the flat rib 1-15 into the tooling fixture, and insert the dispensing machine head into the dispensing port 2-3 until the dispensing chamber 7 is full of adhesive. At this point, the lower end of the dispensing port 2-3 is submerged in the adhesive. After the adhesive has cured, insert the arc-shaped sealing rib 3-1 into the smooth cylindrical hole 2-1 and press in the sealing plug 3 until the second limiting surface 3-2 is flush with the limiting platform 2-2. At this point, the sealing plug 3 blocks both the dispensing port 2-3 and the vent hole 2-4. Align the perimeter 4-1 with the perimeter 1-13. Insert the infrared setting window 2-7 and antenna protrusion 2-8 into the infrared slot 4-4 and outer protrusion 4-3 respectively, until the protruding buckle 1-7 is engaged in the slot 4-2. Finally, use screws to pass through the BOSS post 1-3 and tighten them onto the long stud 4-5. Place the battery into the battery compartment 1-1, connect the battery wiring, install other mechanical seals, and screw the battery compartment sealing cover onto the battery compartment sealing cover thread 1-12, thus completing the IoT water meter remote transmission module.

[0027] Example 2:

[0028] An IoT water meter remote transmission module includes a module box 1, a transparent cover 2, and a module cover 4. The module box 1 has a battery compartment 1-1 for holding batteries. The battery compartment 1-1 has a square-round compartment 1-2 that mates with a wire threading plug 6. The battery compartment 1-1 has openings at both ends to facilitate online battery replacement in a confined space. The module box 1 has a positioning transparent cover 2 and a BOSS post 1-3 for fixing the module cover 4. The transparent cover 2 has a smooth cylindrical hole 2-1 that mates with a sealing plug 3. The lower end of the smooth cylindrical hole 2-1 has a glue-filling port 2-3. The inner wall of the smooth cylindrical hole 2-1 has a limiting platform 2-2, and the limiting platform 2-2 has an exhaust hole 2-4. The vent 2-4 on the transparent cover 2 is higher than the periphery of the assembled module box 1, thus ensuring that the air in the internal cavity can be discharged in time during glue pouring and heat curing, and that the glue flows smoothly. The glue pouring port 2-3 of the transparent cover 2 has the same structural design as the vent 2-4, which makes it easy to complete the waterproof and moisture-proof sealing of the two holes with one action of a sealing plug 3. The outer wall of the transparent cover 2 is provided with an infrared setting window 2-7 and an antenna protrusion 2-8 for placing the antenna. The module cover 4 is provided with an outer protrusion 4-3 that accommodates the antenna protrusion 2-8 and an infrared groove 4-4 that matches the infrared setting window 2-7. The module box 1 and the module cover 4 are connected and fixed, and the transparent cover 2 is embedded between the module box 1 and the module cover 4.

[0029] like Figure 2 As shown, the sealing plug 3 is a soft rubber body. The sealing plug 3 is provided with multiple arc-shaped sealing ribs 3-1 that deform and seal, and a second limiting surface 3-2 that cooperates with the transparent cover 3 to enhance the sealing performance of the device. The transparent cover 3 is made of transparent material, which not only ensures the infrared communication requirements, but also allows for observation of the dispensing process and the cured adhesive at any time.

[0030] like Figure 1 and Figure 2 As shown, the outer wall of module box 1 is provided with a recessed compartment 1-5 for placing the acquisition plate, and a protruding buckle 1-7 for locking the module cover is provided above the recessed compartment 1-5. The inner wall of module box 1 is provided with a locking platform 1-6 for restricting the transparent cover. The multi-buckle design reduces the use of screws and makes production more efficient.

[0031] like Figure 1 and Figure 2 As shown, the module box 1 is provided with positioning holes 1-4, and the module box 1 is provided with a first limiting surface 1-8 for placing the transparent cover 3. The first limiting surface 1-8 is provided with screw platform holes 1-9 for fastening the transparent cover. The positioning holes 1-4 are designed with sufficient depth, which can both sink the screw tail structure and leave space for assembling the anti-tamper lead seal cover.

[0032] like Figure 1 and Figure 2As shown, the module box 1 has a periphery 1-13 forming a potting cavity around its periphery. The lower end of the module box 1 is provided with a flat rib 1-15 to facilitate the placement of the remote transmission module. The square and round compartment 1-2 has a reserved battery compartment 1-1 sealing cover thread 1-12. The reserved battery compartment 1-1 sealing cover thread 1-12 and other parts form a mechanical seal to ensure that the battery can be replaced at any time. The module box 1 has a communication line through blind hole 1-14. The reserved communication line through blind hole 1-14 can facilitate the conversion from wireless to wired without the need for a separate mold. The cross-section of the communication line through blind hole 1-14 is a combination of circle and rectangle. The design of the double-sided flat ribs 1-15 of the module box 1 facilitates the stable placement of the remote transmission module on the potting and assembly line.

[0033] like Figure 2 As shown, the battery compartment 1-1 is provided with a post 1-10 for positioning and fastening the main circuit board 5 and a top post 1-11 for supporting the main circuit board 5.

[0034] like Figure 2 As shown, the wire threading plug 6 is an elastic body. The wire threading plug 6 is provided with a battery wiring through hole 6-1 and a square platform 6-2 to prevent it from rotating freely. The square platform 6-2 is inserted into the square groove, so that the wire threading plug 6 is tightly fitted and aligned with the square and round compartment 1-2, preventing the wire threading plug 6 from rotating freely and thus affecting its use. The square locking position of the wire threading plug 6 and the module box 1 effectively prevents the two battery wires from rotating and tangling, resulting in short circuits or open circuits.

[0035] like Figure 2 As shown, the glue filling chamber 7 is mainly a cavity formed by the module box 1 and the transparent cover 2. The glue filling chamber 7 can accommodate glue that is poured separately or overflows after being poured from inside the module box. There is no need to worry that the glue will climb to the mating surface due to capillary effect and solidify, which will cause difficulties in installing the transparent cover or failure of the seal. It also prevents the transparent cover from being deformed or displaced by stress during the heat curing stage.

[0036] like Figure 1 and Figure 2 and Figure 5 As shown, the module cover 4 is provided with a perimeter 4-1 to prevent the module cover 4 from slipping and to cover the assembly seam. The lower end of the perimeter 4-1 is provided with several fastening slots 4-2 that are adapted to the protrusions 1-7 of the module box 1. There are long studs 4-5 for connecting and fastening with the module box 1 and a large platform 4-6 that can be printed or laser-engraved. The multi-snap design reduces the use of screws and makes production more efficient. The design of the large platform 4-6 of the module cover 4 can accommodate more printed or laser-engraved water meter information.

[0037] The beneficial effects of this invention are: 1. The transparent cover and module box are first fitted together to form a closed cavity before the entire assembly is filled with adhesive, preventing adhesive overflow. This eliminates concerns about adhesive climbing to the mating surface due to capillary effect and curing, which could lead to installation difficulties or sealing failure of the transparent cover. It also prevents the adhesive from deforming or shifting due to stress during the heat curing stage. 2. The vent on the transparent cover is higher than the periphery of the assembled module box, ensuring timely air removal from the internal cavity during adhesive filling and heat curing, and smooth adhesive flow. 3. The adhesive filling port and vent on the transparent cover have the same structural design, allowing for waterproof and moisture-proof sealing of two cavities with a single sealing plug. 4. The transparent cover and module box use a small-circumference planar fit and are fixed with clips or screws, eliminating large gaps and preventing adhesive leakage along the battery wiring due to air pressure imbalance. 5.
