Description

Technical Field

[0001] The utility model relates to a water meter with an antenna, in particular to a water meter mechanical device with a board-mounted sheet metal antenna. Background Art

[0002] A water meter is an instrument used to measure water flow, mostly cumulative flow. It is generally categorized as either volumetric or velocity-based. Meter specifications typically prioritize the intended flow rate and flow range, selecting the specification that most closely matches the commonly used flow rate. To facilitate meter reading, some water meters are equipped with antennas and circuit boards. These circuit boards incorporate an IoT wireless remote transmission module. For example, Chinese patent application No. 202111256561.4, published on December 28, 2021, is titled "A High-Stability Antenna Connection Structure and Method for Water Meter Signal Transmission." The antenna structure includes an antenna mount, a motor, a cam, an antenna, an antenna mounting plate, a screw, a baffle, and a spring. However, conventional communication antennas within mechanical devices typically use conventional materials and designs. These antennas are susceptible to various electromagnetic interference within the cavity, resulting in reduced signal stability and gain. To improve communication quality, a novel antenna design is needed that maintains stable signal transmission and strong gain in complex environments. Summary of the Invention

The antenna is a sheet metal antenna in an elongated strip shape, with both ends stamped and bent and fixed to one edge of the circuit board. The antenna's surface is in close contact with the inner wall of the box body. This structure facilitates the production and assembly of the sheet metal antenna and increases the signal transmission area, thereby improving signal stability and gain.

[0005] A wire lead-out hole is provided at a boss on one side of the top of the box body and / or one side of the box cover, which facilitates the lead-out and connection of the wires.

[0006] A display window is provided on one side of the top of the box body, and the display window corresponds to the display screen electronic components of the circuit board below.

[0007] The bottom of the box body is wavy and corresponds to the outer side of the battery at the bottom of the circuit board inside the box body. The width of the wavy side of the box body is smaller than the width of the bottom of the box body above. The shape of the box cover corresponds to the shape of the opening on one side of the box body and covers it. The circuit board is placed in the rectangular cavity above the box body. This structure facilitates the installation of the battery and the positioning and fixation of the circuit board.

[0008] The outer diameter of one end of the rectangular box cover is provided with an arc-shaped raised lug. The above structure facilitates the opening and closing of the box cover.

[0009] The utility model has a simple and reasonable structural design, is easy to produce and assemble, has good stability, and has a wide range of applications, especially good signal enhancement and gain effects; it is suitable for use as a water meter mechanical device with an onboard sheet metal antenna, as well as a structural improvement of similar products.
