Description
Technical Field
[0001] This application relates to the technical field of support structures, and in particular to an elastic support structure for a remote transmission module induction coil. Background Technology
[0002] Remote water meters and smart water meters are important metering devices in modern water management. Compared with traditional mechanical water meters, they have significant improvements in functionality and application scenarios, such as data uploading capabilities. Remote water meters or smart water meters with data uploading capabilities mainly rely on induction coils and signal processing circuits to convert the mechanical rotation of the meter pointer into electrical signals to achieve flow measurement.
[0003] Currently, water meters with data upload capabilities typically have a metal plate mounted on the pointer, and an electronic module housed inside the meter casing, directly above the metal plate. The electronic module includes a support frame and two induction coils mounted on the support frame to generate an induced magnetic field. As the metal plate rotates, it cuts through this magnetic field. The electronic module then determines the position of the metal plate based on this change in the magnetic field, thus obtaining the flow rate information.
[0004] Existing induction coils are typically fixed to a bracket using adhesive bonding. However, in actual production, when using this conventional method to install induction coils, uneven adhesive application can easily lead to a height difference between the two coils. This height difference affects the relative position between the induction coil and the metal sheet, resulting in signal instability, reduced test pass rate, and impact on the overall performance and reliability of the product. Utility Model Content
[0005] To improve the coil test pass rate, this application provides an elastic support structure for the induction coil of a remote transmission module.
[0006] This application provides an elastic support structure for the induction coil of a remote transmission module, employing the following technical solution:

[0008] Two fixing caps are symmetrically arranged. Each fixing cap has a receiving groove. The fixing bracket has symmetrical fixing grooves. The fixing caps are inserted into the fixing grooves.
[0009] The coils are installed in the receiving slots in a one-to-one correspondence.
[0010] By adopting the above technical solution, the combination structure of fixed bracket and fixed cap realizes the precise installation of induction coil, reduces the height difference problem caused by traditional adhesive method, the overall design of the support structure is reasonable, the operation is simple, and the signal stability and test pass rate are significantly improved.
[0011] Optionally, the fixing component is a fixing screw, and there are multiple fixing screws, each passing through the fixing bracket, and the fixing screw is threadedly connected to the electronic module.
[0012] By adopting the above technical solution, the mounting bracket is detachably and securely connected to the electronic module using multiple fixing screws. This design makes the mounting bracket installation more stable and reliable, while also facilitating disassembly and maintenance.

[0014] By adopting the above technical solution, the fixed bracket is designed as a flexible support structure, which ensures that the coil is stably abutted against the water meter housing after installation. The flexible design of the fixed bracket maintains the coil's contact with and tightness against the inner wall of the water meter housing, ensuring that the height of the two coils remains consistent. Simultaneously, the flexible support structure reduces the impact of external vibrations or shocks, thereby improving signal stability and test pass rate.
[0015] Optionally, the fixing cap is slidably connected to the fixing groove, and a connecting post is provided on the outer wall of the fixing cap on the side away from the receiving groove;
[0016] The fixed bracket has a connecting hole that communicates with the fixed groove and allows the connecting post to pass through. The fixed bracket is slidably connected to a locking post, and the connecting post has a locking hole for the locking post to be inserted.
[0017] By adopting the above technical solution, a sliding connection is formed between the fixing cap and the fixing groove, allowing the outer wall of the fixing cap to abut against the groove wall on the side away from the groove opening. This helps improve the consistency of the induction coil installation. The mating structure of the connecting post and the locking post ensures that the fixing cap can be reliably locked after adjustment, reducing the possibility of loosening due to insecure fixing, thereby improving signal stability.
[0018] Optionally, the fixing bracket is provided with a groove for the locking pin to slide;
[0019] A rubber strip is connected to the side of the locking pin away from the connecting hole, and a locking block is provided on the side of the rubber strip away from the locking pin;
[0020] When the locking pin is inserted into the locking hole, a snap-fit cavity is formed between the locking pin and the groove wall on the side away from the connecting hole, allowing the snap-fit block to snap into it.
[0021] By adopting the above technical solution, the sliding groove design allows the locking pin to slide stably during the connection between the fixing cap and the fixing groove, ensuring accurate insertion of the locking pin into the locking hole and thus improving the connection reliability between the fixing cap and the fixing bracket. The cooperative design of the locking block and the locking cavity further enhances the fixing effect after the locking pin is inserted into the locking hole, effectively reducing the possibility of the locking pin loosening, thereby improving the overall stability of the induction coil installation structure and ensuring the accuracy and consistency of signal transmission.
[0022] Optionally, the card block is a rubber block structure.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0038] This application discloses an elastic support structure for the induction coil of a remote transmission module.
[0039] The inventors of this application discovered that in the prior art, uneven glue application or insufficient assembly precision during the installation of induction coils can easily lead to a height difference between two induction coils, thereby affecting signal stability and test pass rate. To address this, this application mainly adopts an elastic support structure for the induction coil of a remote transmission module. By optimizing the cooperation relationship between the fixing bracket 1, the fixing cap 2, and the coil 3, the installation consistency of the coil 3 is significantly improved, thereby achieving the effect of improving signal stability and test pass rate. The following is a further detailed description of this application.
[0040] Example 1
[0041] See Figure 1 and Figure 2 The present application provides an elastic support structure for the induction coil of a remote transmission module, including a fixed bracket 1, a fixed cap 2 and a coil 3. The fixed bracket 1 is provided with a fixing member to enable the fixed bracket 1 to be detachably fixed to the electronic module.
[0042] Specifically, the fixing component can be a fixing screw 4. In other embodiments, it can also be replaced by other detachable fixing methods such as pins. There are multiple fixing screws 4, each passing through the fixing bracket 1, and the fixing screws 4 are threadedly connected to the electronic module. The connection between the fixing bracket 1 and the fixing screws 4 is a threaded connection, ensuring reliable connection and easy assembly and disassembly.
[0043] The fixed bracket 1 has two fixed slots 11 arranged symmetrically. There are two fixed caps 2, each corresponding to a fixed slot 11, which are inserted into the fixed slots 11. The fixed caps 2 can be cylindrical or other shapes such as frustums. There is friction between the outer wall of the fixed cap 2 and the surrounding wall of the fixed slot 11. When the fixed cap 2 is inserted into the fixed slot 11, the friction prevents it from detaching from the fixed slot 11.
[0044] A guide surface 15 is inclinedly formed on the periphery of the fixing groove 11 at the groove opening. The guide surface 15 can be an arc-shaped transition surface, or in other embodiments, it can be replaced by a multi-segment inclined surface combination structure. The guide surface 15 helps the fixing cap 2 to be smoothly inserted into the fixing groove 11, reducing assembly difficulty. In other embodiments, the guide surface 15 may not be provided on the periphery of the fixing groove 11 at the groove opening.
[0045] There are two coils 3, each corresponding to a fixing cap 2. The fixing cap 2 has a receiving groove 21, and the coils 3 are installed in the receiving groove 21, which improves the consistency of coil installation. This is because the combined structure of the fixing bracket 1 and the fixing cap 2 can effectively avoid the height difference problem caused by traditional adhesive methods. Multiple first wire holes are opened on the side of the fixing cap 2 away from the groove wall of the receiving groove 21, and the fixing bracket 1 has second wire holes corresponding to the first wire holes. During installation, the wires at both ends of the coil 3 protrude through the first wire holes to the outside of the fixing cap 2. When installing the fixing cap 2, first pass the wires at both ends of the coil 3 through the second wire holes; then insert the fixing cap 2 into the fixing groove 11. After the fixing bracket 1 is installed, the wires at both ends of the coil 3 are then connected to the power supply connection points on the circuit board inside the electronic module by electric soldering.
[0046] The fixed bracket 1 can be designed as a flexible support structure, made of a material with elastic deformation capability, such as plastic. When the fixed bracket 1 is installed on the electronic module and the electronic module is installed on the water meter housing, the elastic deformation capability of the fixed bracket 1 generates a force that drives the fixed cap 2 to move towards the inner wall of the water meter housing, so that the coil 3 abuts and presses against the inner wall of the water meter housing. This further ensures that the two coils 3 are at the same height, improving signal stability, increasing the test pass rate, and improving the overall performance and reliability of the product.
[0047] The implementation principle of the elastic support structure for the induction coil of the remote transmission module in Embodiment 1 of this application is as follows:
[0048] The combination of the fixing bracket 1 and the fixing cap 2 enables precise installation of the coil 3, reducing the height difference problem caused by traditional adhesive methods. The elastic design of the fixing bracket 1 keeps the coil 3 in contact with and pressed against the inner wall of the water meter housing, ensuring that the heights of the two coils 3 remain consistent. The overall structure is reasonably designed, easy to operate, and significantly improves signal stability and test pass rate.
[0049] Example 2
[0050] See Figure 3 and Figure 4 The difference between Embodiment 2 and Embodiment 1 is that the fixing cap 2 and the wall of the fixing groove 11 are slidably connected, ensuring that the fixing cap 2 can move smoothly along the fixing groove 11. This allows the outer wall of the fixing cap 2 to be aligned with the side of the fixing groove 11 away from the groove opening, which helps improve the consistency of the coil 3 height and reduces the possibility of insufficient coil 3 height or insufficient elastic deformation capacity of the fixing bracket 1, resulting in the coil 3 failing to abut against the water meter casing and causing a height difference. A connecting post 22 is fixedly connected to the outer wall of the fixing cap 2 away from the receiving groove 21, and the connecting post 22 is coaxially arranged with the fixing cap 2. The shape of the connecting post 22 can be a cuboid structure, or it can be replaced with a polygonal post or other shapes.
[0051] See Figure 4 and Figure 5 The fixed bracket 1 also has connecting holes 12, which are connected to and correspond one-to-one with the fixing groove 11. When the fixing cap 2 slides into the fixing bracket 1, the connecting post 22 slides through the connecting hole 12 until it protrudes outside the fixed bracket 1. A sliding groove 14 is formed on the outer wall of the fixed bracket 1 on the side facing away from the fixing groove 11. The sliding groove 14 has a "T"-shaped groove structure. The fixed bracket 1 is provided with a locking post 13, which slides in the sliding groove 14 and has a "U"-shaped structure. The connecting post 22 has a locking hole 221. When the fixing cap 2 abuts against the groove wall of the fixing groove 11 on the side away from the groove opening, the connecting hole 12 is located outside the fixed bracket 1. At this time, the locking post 13 slides towards the connecting post 22, so that both ends of the locking post 13 slide into the connecting hole 12 respectively, thereby connecting and fixing the fixing cap 2 and the fixed bracket 1.
[0052] A rubber strip 131 is fixedly connected to the side of the locking pin 13 away from the connecting hole 12. A locking block 132 is fixedly connected to the side of the rubber strip 131 away from the locking pin 13. The locking block 132 can be a rubber block structure with a certain degree of elasticity. When the locking pin 13 is inserted into the locking hole 221, a locking cavity 141 is formed between the locking pin 13 and the groove wall of the slide groove 14 away from the connecting hole 12. At this time, the locking block 132 is inserted into the locking cavity 141, which can prevent the locking pin 13 from disengaging from the connecting hole 12, ensuring reliable locking and easy disassembly.
[0053] The implementation principle of the elastic support structure for the induction coil of the remote transmission module in Embodiment 2 of this application is as follows:
[0054] During installation, slide the fixing cap 2 into the fixing groove 11, then slide the locking pin 13 so that both ends of the locking pin 13 are inserted into the connecting holes 12 respectively. Finally, insert the clip 132 into the clip cavity 141 to achieve a fixed connection between the fixing cap 2 and the fixing bracket 1. After that, the fixing bracket 1 can be fixed on the circuit board of the electronic module and the wires at both ends of the coil 3 can be connected and fixed.
[0055] Example 3
[0056] See Figure 3 The difference between Embodiment 3 and Embodiment 2 is that the fixing cap 2 is further provided with a connecting sleeve 5. The connecting sleeve 5 is located inside the receiving groove 21, and the outer peripheral sidewall of the connecting sleeve 5 abuts against the peripheral groove wall of the receiving groove 21. During installation, the connecting sleeve 5 is first placed on the outer peripheral side of the coil 3, and then the connecting sleeve 5 is installed inside the receiving groove 21. The connecting sleeve 5 can be made of rubber, or it can be replaced with other flexible materials such as polyurethane. The setting of the connecting sleeve 5 can effectively protect the coil 3, improve the installation stability of the coil 3, and reduce the possibility of damage to the coil 3 during assembly.
[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
