Description

Technical Field

[0001] This utility model belongs to the field of smart water meter technology, specifically relating to a smart water meter control component and a smart water meter. Background Technology

[0002] Smart water meters integrate various advanced technologies such as the Internet of Things, big data, and cloud computing, enabling functions such as remote data transmission, real-time data analysis, and intelligent management. With continuous technological advancements, smart water meters are becoming increasingly feature-rich and intelligent, thus finding widespread application in various fields including residential homes, commercial buildings, industrial production, and water conservancy projects.

[0003] Currently, the electronic components of smart water meters need to meet the IP68 protection rating. This typically requires potting compound to fully cover the PCB (Printed Circuit Board), with protective covers preventing the compound from entering certain components. Existing protective covers are usually mounted on top of the PCB using interference fits. However, this connection method has some drawbacks. Firstly, a large interference fit can make the protective cover difficult to install, resulting in low yield and production efficiency during mass production. Secondly, a small interference fit can lead to an insecure installation; after potting, the compound can exert an upward buoyancy force on the cover, potentially causing it to loosen and lose its protective function.

[0004] Therefore, there is an urgent need to propose a smart water meter control component and a smart water meter to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to at least solve the problems of difficulty in installing the protective cover and the housing body, or the problem of insecure installation. This purpose is achieved through the following technical solution:

[0006] The first aspect of this utility model provides a smart water meter control component, comprising:

[0007] The housing body has a cavity, a connecting sleeve is provided at the bottom of the cavity, a blind hole is provided at the center of the connecting sleeve, and a notch communicating with the blind hole is provided on the side wall of the connecting sleeve;

[0008] A protective cover is disposed inside the cavity. The protective cover is provided with a connecting post, which is inserted into the blind hole and the connecting post and the connecting sleeve are interference-fitted.

[0009] By using the smart water meter control component in this technical solution, the protective cover and the housing body are connected via connecting posts and connecting sleeves. The connecting posts and connecting sleeves employ an interference fit, ensuring a secure connection and effectively reducing the possibility of the protective cover and housing body becoming loose. Because of the interference fit between the connecting posts and connecting sleeves, a notch is created in the side wall of the connecting sleeve. When the connecting post is inserted into the blind hole, the connecting sleeve undergoes a certain deformation, allowing the connecting post to be better inserted into the blind hole. Therefore, the connecting posts and connecting sleeves achieve both a stable connection and easy assembly.

[0010] In addition, the intelligent water meter control component of this utility model may also have the following additional technical features:

[0011] In some embodiments of this invention, the depth of the notch is greater than the height of the connecting post.

[0013] In some embodiments of this utility model, potting compound is provided in the cavity, and the part of the circuit board not isolated by the protective cover is in contact with the potting compound.

[0014] In some embodiments of this utility model, the circuit board includes a substrate and a first device disposed on the substrate, the protective cover includes a first cover body having a first cavity, the first device being located inside the first cavity, the connecting post being disposed at the opening edge of the first cover body, and the first cover body being used to isolate the potting compound.

[0015] In some embodiments of this utility model, the circuit board further includes a second device disposed on the substrate, the protective cover includes a second cover body having a second cavity, the second device being located inside the second cavity, and the second cover body being used to isolate the potting compound.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0036] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0037] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence.

[0039] Figure 1 A partial structural diagram of a smart water meter control component according to an embodiment of the present invention is shown schematically. Figure 2 A partial cross-sectional view of a smart water meter control component according to an embodiment of the present invention is shown schematically. Figure 3 A schematic diagram of the structure of the base 110 according to an embodiment of the present invention is shown. Figure 4 yes Figure 3 A magnified view of a portion of point A in the middle. Figure 5 A schematic diagram of the structure of the protective cover 200 according to an embodiment of the present invention is shown; as follows: Figures 1 to 5 As shown, this utility model proposes a smart water meter control component, which includes a housing body 100 and a protective cover 200. The housing body 100 has a cavity 101, and a connecting sleeve 120 is provided at the bottom of the cavity 101. The connecting sleeve 120 has a blind hole 121 at its center, and a notch 122 communicating with the blind hole 121 is opened on the side wall of the connecting sleeve 120. The protective cover 200 is disposed inside the cavity 101, and the protective cover 200 is provided with a connecting post 210. The connecting post 210 is inserted into the blind hole 121, and the connecting post 210 and the connecting sleeve 120 are interference-fitted.

[0040] By using the smart water meter control component in this technical solution, the protective cover 200 and the housing body 100 are connected via a connecting post 210 and a connecting sleeve 120. The connecting post 210 and the connecting sleeve 120 employ an interference fit, ensuring a secure connection and effectively reducing the possibility of the protective cover 200 and the housing body 100 becoming loose. Because the connecting post 210 and the connecting sleeve 120 are interference-fitted, a notch 122 is provided on the side wall of the connecting sleeve 120. When the connecting post 210 is inserted into the blind hole 121, the connecting sleeve 120 undergoes a certain deformation, allowing the connecting post 210 to better insert into the blind hole 121. Therefore, the connecting post 210 and the connecting sleeve 120 achieve both a stable connection and easy assembly.

[0041] Optionally, the housing body 100 includes a base 110 and a top cover (not shown in the figure), with the base 110 and the top cover sealed together to form a waterproof structure. Optionally, the base 110 and the top cover are inserted together and fixedly connected by bolts. A limiting protrusion 130 is provided along the circumference of the base 110, and an insertion portion 140 is formed above the limiting protrusion 130. The insertion portion 140 is provided with multiple locking holes 141, and correspondingly, multiple locking protrusions are provided on the inner side of the opening of the top cover. During assembly, the top cover is fastened onto the base 110, and the opening of the top cover and the insertion portion 140 are inserted together, with the locking protrusions inserted into the locking holes 141. In this embodiment, the connecting post 210 is provided at the bottom of the base 110, and the protective cover 200 is connected to the base 110 through the connecting post 210.

[0042] Further, see Figure 2 The depth of the notch 122 is greater than the height of the connecting post 210.

[0043] Understandably, when the depth of the notch 122 is greater than the height of the connecting post 210, the depth of the blind hole 121 should also be greater than the height of the connecting post 210. After installation, a gap is formed between the insertion end of the connecting post 210 and the bottom of the blind hole 121. In this case, the gap between the insertion end of the connecting post 210 and the bottom of the blind hole 121 is connected to the notch 122. During assembly, air inside the blind hole 121 can be discharged through the notch 122 to prevent air pressure from creating resistance to the insertion of the connecting post 210, thus reducing the difficulty of installing the protective cover 200. Optionally, chamfering or rounding the top of the connecting post 210 makes it easier to insert the connecting post 210 into the connecting sleeve 120.

[0044] Furthermore, the smart water meter control component also includes a circuit board 300, which is disposed inside the cavity 101, and a portion of the circuit board 300 is isolated by a protective cover 200.

[0045] The main functions of circuit board 300 include measuring water flow, transmitting data, processing and storing data. The configuration of circuit board 300 is a mature technical solution in this field, and its structure and function will not be elaborated further here. The protective cover 200 serves to protect the electronic components within circuit board 300, preventing moisture, dust, and harmful foreign objects from entering.

[0046] Furthermore, the cavity 101 is filled with potting compound, and part of the circuit board 300 is in contact with the potting compound. The parts of the circuit board 300 that are not isolated by the protective cover 200 are in contact with the potting compound.

[0047] The potting compound provides a protective barrier for the circuit board 300, preventing moisture, dust, or harmful foreign matter from contacting it and ensuring a longer service life. Optionally, the potting compound is a high-temperature resistant colloid, exhibiting good stability in high-temperature environments and still effectively protecting the circuit board 300. Optionally, the potting compound can be epoxy resin, polyurethane adhesive, or silicone gel, selected according to specific application requirements. Of course, the parts of the circuit board 300 that should not come into contact with the potting compound are isolated by the protective cover 200. Furthermore, the distance between the upper surface 400 of the potting compound and the surface of the circuit board 300 is greater than 6mm, thereby achieving waterproofing and providing effective protection.

[0048] Furthermore, Figure 6 A schematic diagram of the circuit board 300 according to an embodiment of the present invention is shown. See also Figure 5 and Figure 6 The circuit board 300 includes a substrate 310 and a first device 320 disposed on the substrate 310. The protective cover 200 includes a first cover 220, the first cover 220 having a first cavity 221, the first device 320 being located inside the first cavity 221, and a connecting post 210 disposed at the opening edge of the first cover 220. The first cover 220 is used to isolate potting compound.

[0049] The first device 320 protrudes from the surface of the substrate 310, thus the first cavity 221 provides a accommodating space for the first device 320. By placing the connecting post 210 at the edge of the opening of the first cover 220, the opening of the first cover 220 can be made to contact the substrate 310, thereby effectively preventing potting compound from entering the first cavity 221 from the gap between the substrate 310 and the first cover 220. In this technical solution, the first cavity 221 is set as a cuboid according to the shape of the first device 320. In other embodiments, the shape of the first cavity 221 can be set according to the shape of the protected device.

[0050] Further, see also Figure 5 and Figure 6 The circuit board 300 also includes a second device 330 disposed on the substrate 310. The protective cover 200 includes a second cover 230, the second cover 230 having a second cavity 231, the second device 330 being located inside the second cavity 231, and the second cover 230 being used to isolate potting compound.

[0051] The second device 330 protrudes from the surface of the substrate 310. Understandably, the shape of the second cavity 231 is set according to the shape of the first device 320.

[0052] Furthermore, the first cover 220 and the second cover 230 are connected by a connecting plate 240, which is spaced apart from the circuit board 300. The connecting plate 240 is provided with a glue inlet 241 that allows potting compound to pass through.

[0053] The first cover 220 and the second cover 230 are connected by a connecting plate 240, allowing the protective cover 200 to be inserted into the cavity 101 of the housing body 100 in one go. Optionally, the first cover 220, the connecting plate 240, and the second cover 230 are integrally formed. A glue inlet 241 is provided on the connecting plate 240, allowing potting compound to contact the circuit board 300 through the inlet 241. Optionally, the shape of the glue inlet 241 can be triangular, rectangular, or circular, and there can be one or more of them. Optionally, the connecting plate 240 and the circuit board 300 are parallel and spaced apart.

[0054] Optionally, the outer edge of the connecting plate 240 is provided with a flange 242. By adding the flange 242, the overall structural strength can be increased. At the same time, the contact area between the protective cover 200 and the potting compound is increased to enhance the stability of the connection.

[0055] Furthermore, multiple connecting posts 210 are provided; multiple connecting posts 210 are all provided on the first cover 220; or, multiple connecting posts 210 are all provided on the second cover 230; or, the first cover 220 and the second cover 230 are each provided with at least one connecting post 210.

[0056] Understandably, the connecting post 210 can be located at the opening edge of the cover, on the side wall of the cover, or in other convenient insertion positions. For example, this embodiment has three connecting posts 210, all located at the opening edge of the first cover 220. Correspondingly, the base 110 has three connecting sleeves 120, with each connecting post 210 and connecting sleeve 120 corresponding to the other. Of course, in other embodiments, the connecting post 210 can be located at any position on the protective cover 200, as long as a stable and reliable connection with the connecting sleeve 120 is possible; its position is not specifically limited here. Understandably, when the connecting post 210 needs to pass through the circuit board 300, a first clearance hole 301 should be provided on the circuit board 300.

[0057] Furthermore, the circuit board 300 is fixedly connected to the housing body 100 by screws.

[0058] Screws are used to connect the circuit board 300 and the housing body 100, making the connection convenient and reliable. A connecting part 150 protrudes from the base 110, and the connecting part 150 has a threaded hole, allowing the screw to be threaded into the connecting part 150. Correspondingly, the circuit board 300 has a second clearance hole 302 that allows the screw to pass through.

[0059] The assembly method of the smart water meter control component provided in this technical solution is as follows:

[0060] The circuit board 300 is placed in the base 110, and the circuit board 300 and the base 110 are fixed with screws. The protective cover 200 is placed in the base 110, with the first cover 220 facing the first device 320 and the second cover 230 facing the second device 330, and the connecting post 210 is inserted into the blind hole 121 on the connecting sleeve 120. Then, potting compound is injected into the base 110 to cover the circuit board 300.

[0061] Furthermore, this technical solution also provides a smart water meter, including the smart water meter control component described in the above embodiments. By using the housing body 100 and protective cover 200 described in the above embodiments, the problems of difficulty in installing the protective cover 200 due to excessive interference fit and unreliable installation due to insufficient interference fit in the prior art are avoided, thus achieving fast and reliable installation of the protective cover 200.

[0062] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
