Description

Technical Field

[0001] This utility model relates to the field of electronic modules for smart water meters, and in particular to an electronic module structure for smart water meters. Background Technology

[0002] In order to perform metering, signal transmission, and remote valve switching, an electronic module is usually installed inside the smart water meter.

[0003] Traditional electronic module designs place the antenna and circuit board together in a cavity between the upper and lower boxes. After filling the cavity with adhesive, both the circuit board and the antenna are encased in the adhesive, forming the electronic module structure. However, in this structure, because the antenna is also encased in adhesive, it affects the antenna signal, thus impacting usability. While encasing only the circuit board in adhesive and reserving space for the antenna in the upper box does not affect the antenna signal, it creates a larger cavity within the module, which compromises IP68 performance. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the existing technology and provide an electronic module structure for smart water meters.

[0005] The objective of this utility model can be achieved through the following technical solutions: An electronic module structure for a smart water meter includes an upper cover and a lower box fixed together; an inner cover is disposed between the upper cover and the lower box; a circuit board is installed at the bottom of the inner cover and an antenna is installed at the top; the antenna passes through the inner cover and is connected to the circuit board; the lower box and the inner cover are sealed with potting compound.

[0006] Furthermore, a rubber plug is provided at the position where the antenna is inserted on the inner cover; the antenna is inserted through the rubber plug.

[0007] Furthermore, the upper cover and the lower box are welded together using an ultrasonic welding process.

[0008] Furthermore, the electronic module structure is fixedly installed inside the water meter housing by a top cover.

[0009] Compared with the prior art, the present invention has the following advantages: This invention adds an inner cover between the upper cover and the lower box, with the circuit board installed at the bottom of the inner cover and the antenna installed at the top. In this way, the upper cover and the lower box form a sealed large cavity, and the inner cover further divides the large cavity into upper and lower cavities. The circuit board is located in the lower cavity, and after being sealed with glue, it can be well wrapped without any cavities. The antenna is located in the upper cavity and will not be affected by the glue. This meets the IP68 waterproof requirement without affecting the antenna signal, thus ensuring the antenna's transmission performance. Attached Figure Description
