[0012] The battery case is configured to move relative to the bottom shell to switch between a first state and a second state.

[0013] When the battery case is in the first state, the second access port is opposite to the top cover, so that the top cover blocks the second access port;

[0014] When the battery case is in the second state, the second loading / unloading port is misaligned with the top cover to open the second loading / unloading port.

[0015] In some embodiments, the bottom shell further has a first loading / unloading port, which communicates with the first cavity, and the top cover is disposed at the first loading / unloading port, with the first loading / unloading port and the second loading / unloading port facing the same direction.

[0016] In some embodiments, the bottom shell has a positioning cavity that is separated from the first cavity, and when the battery case is in the first state, a portion of the battery case is located within the positioning cavity.

[0017] In some embodiments, the battery casing further has a clearance opening connected to the second access port, and the orientation of the clearance opening is perpendicular to the second access port.

[0018] When the battery casing is in the first state, the clearance opening is opposite to the inner wall of the positioning cavity, so that the inner wall of the positioning cavity blocks the clearance opening.

[0019] In some embodiments, the bottom shell has a first guide portion and the battery casing has a second guide portion, the first guide portion and the second guide portion being guided and engaged so that the second guide portion can move relative to the first guide portion in a first direction or a second direction that are opposite to each other;

[0020] When the second guide portion moves along the first direction, the battery case switches from the first state to the second state;

[0021] When the second guide moves along the second direction, the battery case switches from the second state to the first state.

[0022] In some embodiments, the first guide portion is a guide groove formed in the bottom shell, the second guide portion is a guide block, the guide groove extends along the first direction, and the guide block is movably embedded in the guide groove.

[0024] In some embodiments, the bottom shell has a first snap-fit ​​portion, and the battery casing has a second snap-fit ​​portion;

[0025] When the battery case is in the first state, the second snap-fit ​​part engages with the first snap-fit ​​part.

[0026] When the battery case is in the second state, the second latching part is separated from the first latching part.

[0027] In some embodiments, the battery housing is rotatably connected to the bottom housing, and the battery housing is configured to rotate in a third or fourth direction that is in opposite directions.

[0028] When the battery casing rotates along the third direction, the battery casing switches from the first state to the second state;

[0029] When the battery casing rotates along the fourth direction, the battery casing switches from the second state to the first state.

[0030] In some embodiments, when the battery casing rotates along the third or fourth direction, the battery casing rotates around a preset axis, the direction of which is consistent with the orientation of the second pick-up / drop-off port.

[0031] In some embodiments, the bottom shell includes a first limiting portion, and the battery casing includes a second limiting portion. When the battery casing is in the first state, the first limiting portion limits the second limiting portion in the fourth direction.

[0032] In some embodiments, the water meter controller further includes a connecting wire, the two ends of which are respectively connected to the metering component and the battery, so that the metering component is electrically connected to the battery;

[0033] The bottom shell has a wire harness groove located between the first cavity and the second cavity, and part of the connecting wire is snapped into the wire harness groove.

[0034] In some embodiments, the water meter controller includes a plurality of fasteners, some of which are detachably inserted through the upper cover and the bottom shell to fix the upper cover and the bottom shell, and another plurality of which are detachably inserted through the upper cover and the battery housing to fix the upper cover and the battery housing.

[0035] In the water meter controller provided in this application, the metering component and the battery are respectively disposed in the bottom shell and the battery shell. The top cover seals the first access port, allowing the metering component to be enclosed in the first cavity, thus protecting it. The battery shell is movably connected to the bottom shell, allowing it to move relative to the bottom shell and switch between a first state and a second state. When the battery shell moves relative to the bottom shell to the second state, the second access port is opened, allowing the battery in the second cavity of the battery shell to be removed through the second access port, and the replacement battery to be installed in the second cavity through the second access port. Subsequently, by moving the battery shell relative to the bottom shell to the first state, the second access port is sealed by the top cover, thus enclosing the battery in the second cavity. During battery replacement, the top cover always seals the first access port, preventing the disassembly of the top cover and the bottom shell and preventing exposure of the metering component, thereby making the battery replacement process simple and convenient.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0056] A water meter controller connects to the water meter's meter head and calculates water consumption based on the meter's readings. The controller primarily consists of a main body and a battery, which powers the main body. The battery needs to be replaced after prolonged use and depletion.

[0057] The current water meter controller has its battery located inside. When replacing the battery, multiple bolts need to be removed to remove the battery cover, which makes the battery replacement process cumbersome and inconvenient.

[0058] In the water meter controller proposed in this application, the metering component and the battery are respectively disposed in the bottom shell and the battery shell. The top cover seals the first access port, allowing the metering component to be enclosed in the first cavity, thus protecting it. The battery shell is movably connected to the bottom shell, allowing it to move relative to the bottom shell and switch between a first state and a second state. When the battery shell moves relative to the bottom shell to the second state, the second access port is opened, allowing the battery in the second cavity of the battery shell to be removed through the second access port, and the replacement battery to be installed in the second cavity through the second access port. Subsequently, by moving the battery shell relative to the bottom shell to the first state, the second access port is sealed by the top cover, thus enclosing the battery in the second cavity. During battery replacement, the top cover always seals the first access port, preventing the disassembly of the top cover and the bottom shell and preventing exposure of the metering component, thereby making the battery replacement process simple and convenient.

[0059] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0060] This application discloses a water meter controller, with reference to... Figure 1 As shown, it includes a bottom housing 100, a battery housing 200, a metering component 300, a battery 400, and a top cover 500. This water meter controller can be used in wireless earphones.

[0061] The base shell 100 is the basic component of the water meter controller of this application, and it can provide an installation base for at least some other components of the water meter controller. The base shell 100 can be made of polymer, making it relatively lightweight. Alternatively, the base shell 100 can be made of metal, which would provide better structural strength, resulting in improved durability and reliability.

[0062] The bottom shell 100 has a first cavity 110, which is a hollow structure within the bottom shell 100. The bottom shell 100 also has a first access port 120, which can be located on the surface of the bottom shell 100 and communicates with the first cavity 110, allowing the first cavity 110 to communicate with the outside of the bottom shell 100 through the first access port 120. The metering component 300 is disposed within the first cavity 110 of the bottom shell 100. Specifically, when assembling the water meter controller of this application, the metering component 300 can be installed in the first cavity 110 of the bottom shell 100 through the first access port 120.

[0063] The battery casing 200 has a second cavity 210, which is a hollow structure within the battery casing 200. The battery casing 200 also has a second access port 220, which can be located on the surface of the battery casing 200 and communicates with the second cavity 210, allowing the second cavity 210 to communicate with the outside of the battery casing 200 through the access port 220. The battery 400 is disposed within the second cavity 210 of the battery casing 200. Specifically, when assembling the water meter controller of this application, the battery 400 can be installed in the second cavity 210 of the battery casing 200 through the second access port 220.

[0064] The battery 400 is electrically connected to the metering component 300, enabling the battery 400 to power the metering component 300. The metering component 300 can also be electrically connected to the meter head of the water meter, allowing the signal detected by the sensor inside the meter head to be transmitted to the metering component 300, which can then calculate the actual water flow data based on the electrical signal transmitted from the meter head.

[0065] The upper cover 500 is detachably mounted on the bottom shell 100, and the upper cover 500 blocks the first access port 120 of the bottom shell 100. This allows the metering component 300 to be enclosed within the first cavity 110 by the upper cover 500, ensuring that the bottom shell 100 and the upper cover 500 can adequately protect the metering component 300. Specifically, when assembling the water meter controller of this application, the metering component 300 can be first installed into the first cavity 110 through the first access port 120, and then the upper cover 500 can be connected to the bottom shell 100 to enclose the metering component 300 within the first cavity 110.

[0066] The battery case 200 is movably connected to the bottom case 100, allowing the battery case 200 to move relative to the bottom case 100. This enables the relative position of the battery case 200 and the bottom case 100 to change, allowing the battery case 200 to switch between a first state and a second state. When the battery case 200 moves to the second state relative to the bottom case 100, the second access port 220 of the battery case 200 is misaligned with the top cover 500, ensuring that the top cover 500 does not obstruct the second access port 220. The second access port 220 is then opened, allowing the battery 400 inside the second cavity 210 of the battery case 200 to be removed through the second access port 220, and the replacement battery 400 to be installed into the second cavity 210 through the second access port 220.

[0067] When the battery case 200 moves to the first state relative to the bottom case 100, the second take-out port 220 of the battery case 200 is opposite to the top cover 500, so that the top cover 500 blocks the second take-out port 220 and the second take-out port 220 is closed, so that the battery 400 can be sealed in the second cavity 210 of the battery case 200.

[0068] Therefore, when it is necessary to replace the battery 400 in the second cavity 210 of the battery case 200, the battery case 200 can be moved relative to the bottom shell 100 to switch to the second state, the battery 400 can be removed, and the new battery 400 can be installed in the second cavity 210. Subsequently, the battery case 200 can be moved relative to the bottom shell 100 to the first state, so that the second access port 220 is blocked by the top cover 500, thus sealing the battery 400 in the second cavity 210. During the battery 400 replacement process, the top cover 500 is always connected to the bottom shell 100 to block the first access port 120, without having to disassemble the top cover 500 from the bottom shell 100, thus avoiding exposure of the metering component 300, making the battery 400 replacement process simple and convenient.

[0069] In addition, a lead seal can be installed at the connection between the top cover 500 and the bottom shell 100, so that the lead seal will not be damaged when the battery 400 is replaced, thus avoiding the risk of the metering component 300 being damaged or modified.

[0070] In some implementations, reference Figure 1 As shown, to make the structure of the water meter controller of this application more compact, the orientation of the first access port 120 and the second access port 220 can be set to be the same, making the structure of the water meter controller of this application more compact. In addition, the upper cover 500 can be a flat plate structure, so that the upper cover 500 can block both the first access port 120 and the second access port 220, thereby avoiding the use of an irregular structure for the upper cover 500, achieving the goal of simplifying the structure of the upper cover 500 and reducing the cost of the water meter controller of this application.

[0071] Specifically, the thickness direction of the metering component 300 in this application can be set to be consistent with the orientation of the first loading / unloading port 120, so that the metering component 300 can be laid flat in the first cavity 110 of the bottom shell 100. The battery 400 can be a cylindrical structure, and the direction of the axis of the battery 400 can be set to be consistent with the orientation of the second loading / unloading port 220.

[0072] In some implementations, reference Figure 1 and Figure 4 As shown, the bottom shell 100 of this application may also be provided with a positioning cavity 130. The positioning cavity 130 is also a cavity structure within the bottom shell 100, and the positioning cavity 130 is separated from the first cavity 110. When the battery case 200 is in the first state, part of the battery case 200 is located within the positioning cavity 130 of the bottom shell 100. In this way, the inner wall of the positioning cavity 130 can limit the position of the battery case 200, making the structure more stable when the battery case 200 is in the first state.

[0073] Specifically, when the battery housing 200 switches from the first state to the second state, the battery housing 200 can move in a direction away from the positioning cavity 130, causing the battery housing 200 to detach from the positioning cavity 130. When the battery housing 200 switches from the second state to the first state, the battery housing 200 can move in a direction toward the positioning cavity 130, causing a portion of the battery housing 200 to enter the positioning cavity 130.

[0074] In some implementations, reference Figure 1 and Figure 4As shown, the battery casing 200 of this application may also be provided with a clearance opening 230, which is also an opening on the surface of the battery casing 200. The clearance opening 230 is connected to the second access opening 220 of the battery casing 200, and the orientation of the clearance opening 230 is perpendicular to the orientation of the second access opening 220. When the battery casing 200 is in the first state, the clearance opening 230 is opposite to the inner wall of the positioning cavity 130 of the bottom shell 100, so that the inner wall of the positioning cavity 130 of the bottom shell 100 can block the clearance opening 230, so that the battery 400 can be sealed in the second cavity 210 of the battery casing 200. This can save material for the battery casing 200, making the structure of the battery casing 200 more compact. Correspondingly, it can make the structure of the water meter controller of this application more compact.

[0075] In addition, by providing a clearance opening 230 connected to the second loading and unloading port 220 in the battery housing 200, the opening on the surface of the battery housing 200 is made larger, making the process of loading and unloading the battery 400 from the second cavity 210 simpler and more convenient.

[0076] In some implementations, reference Figures 1 to 3 As shown, in order to allow the battery housing 200 to be movably connected to the bottom housing 100, and to allow the battery housing 200 to switch between a first state and a second state, the bottom housing 100 may include a first guide portion 140, and the battery housing 200 may include a second guide portion 240. The first guide portion 140 and the second guide portion 240 are guided and engaged in opposite directions, allowing the second guide portion 240 to move relative to the first guide portion 140 along either the first or second direction. Both the first and second directions are... Figure 1 The X-axis is parallel to it.

[0077] When the second guide portion 240 moves along the first direction, the battery case 200 switches from the first state to the second state, causing the second loading / unloading port 220 of the battery case 200 to gradually misalign with the top cover 500 until the second loading / unloading port 220 is completely misaligned with the top cover 500, thus fully opening the second loading / unloading port 220. During this process, the first guide portion 140 always slides along the first direction, and correspondingly, the clearance port 230 of the battery case 200 also moves along the inner wall of the positioning cavity 130 away from the bottom cover 100, so that the battery case 200 can always slide stably along the first direction, preventing the battery case 200 from tilting.

[0078] As the second guide portion 240 moves along the second direction, the battery case 200 switches from the second state to the first state, causing the second loading / unloading port 220 of the battery case 200 to gradually align with the top cover 500 until the second loading / unloading port 220 is completely aligned with the top cover 500, thus completely closing the second loading / unloading port 220. During this process, the second guide portion 240 always slides along the second direction. Correspondingly, the clearance port 230 of the battery case 200 also moves along the direction towards the inner wall of the positioning cavity 130 of the bottom shell 100, allowing the battery case 200 to slide stably along the second direction and preventing the battery case 200 from tilting.

[0079] Specifically, the first guide portion 140 can be a guide groove provided on the bottom shell 100, with one end of the guide groove extending to the surface of the bottom shell 100 to form an opening. The second guide portion 240 is a guide block provided on the surface of the battery case 200, with the guide block movably embedded in the guide groove, so that the guide block can move in the guide groove along a first direction and a second direction that are opposite to each other.

[0080] The battery case 200 is switched between the first state and the second state by moving the battery case 200. This makes the switching process simple and efficient. During this process, the top cover 500 does not move and can always keep the first loading and unloading port 120 of the bottom case 100 blocked, thus preventing the metering component 300 from being exposed.

[0081] In some implementations, reference Figure 4 As shown, the bottom shell 100 of this application may also be provided with a first snap-fit ​​portion 150, and the battery shell 200 may also be provided with a second snap-fit ​​portion 250. When the battery shell 200 is in the first state, the first snap-fit ​​portion 150 and the second snap-fit ​​portion 250 snap-fit ​​together, so that the battery shell 200 and the bottom shell 100 can be further fixed together, thereby making the battery shell 200 stably connected to the bottom shell 100 when it is in the first state, and thus making the battery shell 200 stably maintain the first state.

[0082] The first snap-fit ​​portion 150 can be disposed within the mounting cavity of the bottom shell 100, and the second snap-fit ​​portion 250 can be disposed on the side of the battery shell 200 facing the inner wall of the mounting cavity. When the battery shell 200 is in the first state, a portion of the battery shell 200 is located within the mounting cavity, allowing the first snap-fit ​​portion 150 and the second snap-fit ​​portion 250 to engage.

[0083] For details, please refer to Figure 5As shown, the first latching part 150 can be configured as a latching groove formed in the mounting cavity, and the second latching part 250 can be configured as a deformable buckle. The latching groove is oriented in the first direction. Correspondingly, when the battery case 200 moves to the first state along the second direction, the buckle can move toward the latching groove. The buckle is deformed by the pressure of the inner wall of the latching groove, so that the buckle can be latched into the latching groove, thereby fixing the buckle in the latching groove.

[0084] When the battery casing 200 moves to the second state along the first direction, the buckle can move away from the slot. The buckle is deformed by the inner wall of the slot, so that the buckle can be released from the slot.

[0085] Of course, in other embodiments, the first snap-fit ​​portion 150 may also be a buckle provided in the mounting cavity, and the second snap-fit ​​portion 250 may also be a slot provided on the surface of the battery case 200, so that the first snap-fit ​​portion 150 and the second snap-fit ​​portion 250 can also snap-fit ​​together.

[0086] In some implementations, reference Figure 6 As shown, to enable the battery housing 200 to be movably connected to the bottom housing 100, allowing the battery housing 200 to switch between a first state and a second state, the bottom housing 100 and the battery housing 200 can also be rotatably connected, allowing the battery housing 200 to rotate relative to the bottom housing 100 to either the first or second state. The battery housing 200 is configured to rotate relative to the bottom housing 100 along a third or fourth direction that is in opposite directions, thereby allowing the battery housing 200 to switch between the first and second states. When the battery housing 200 rotates along the third or fourth direction, the battery housing 200 rotates around... Figure 6 Rotation along the Z-axis.

[0087] For details, please refer to Figure 7 and Figure 8 As shown, a pivot 270 can be provided on the edge of the battery case 200. The pivot 270 of the battery case 200 can be inserted into the bottom shell 100, so that the battery case 200 can rotate relative to the bottom shell 100.

[0088] When the battery case 200 rotates relative to the bottom case 100 in a third direction, the battery case 200 can switch from the first state to the second state, so that the second access port 220 of the battery case 200 is misaligned with the top cover 500. In this way, the second access port 220 is opened, and the battery 400 can be taken out or put into the second cavity 210 of the battery case 200 through the second access port 220.

[0089] When the battery case 200 rotates relative to the bottom case 100 in the fourth direction, the battery case 200 can switch from the second state to the first state, so that the second take-out port 220 of the battery case 200 is opposite to the top cover 500, thus the second take-out port 220 is closed and the battery 400 is sealed in the second cavity 210 of the battery case 200.

[0090] It should be understood that when the battery housing 200 rotates in a third direction, the second opening 220 of the battery housing 200 gradually misaligns with the top cover 500 until the second opening 220 is completely misaligned with the top cover 500 and is fully opened. When the battery housing 200 rotates in a fourth direction, the second opening 220 of the battery housing 200 gradually faces the top cover 500 until the second opening 220 is completely facing the top cover 500 and is blocked.

[0091] Since the battery case 200 and the bottom case 100 are rotatably connected, the battery case 200 and the bottom case 100 are always connected when the battery case 200 switches between the first state and the second state. This prevents the battery case 200 from separating from the bottom case 100, avoids the battery case 200 and the bottom case 100 from being disassembled and reassembled, and further improves the battery replacement efficiency.

[0092] In some implementations, reference Figure 6 As shown, when the battery casing 200 rotates in a third or fourth direction, the battery casing 200 rotates around a preset axis, which is the... Figure 6 The Z-axis is preset to align with the orientation of the second pick-up / placement port 220. This ensures that the orientation of the second pick-up / placement port 220 remains constant when the battery case 200 switches between the first and second states. Consequently, it prevents the battery 400 within the second cavity 210 from tilting, thus preventing the battery 400 from sliding out of the battery case 200 when it rotates.

[0093] In some implementations, reference Figure 6 As shown, the bottom shell 100 of this application may include a first limiting part 160, and the battery shell 200 may include a second limiting part 260. When the battery shell 200 is in the first state, the first limiting part 160 and the second limiting part 260 cooperate to limit the second limiting part 260 in the fourth direction, thereby limiting the battery shell 200 and preventing it from rotating excessively in the fourth direction.

[0094] Specifically, the first limiting part 160 can be a limiting groove formed on the bottom shell 100, and the second limiting part 260 can be a limiting block on the battery shell 200. The limiting block is embedded in the limiting groove, so that the inner wall of the limiting groove can limit the limiting block in the fourth direction. The groove shape of the limiting groove can match the shape of the limiting block, so that the outer wall of the limiting block abuts against the inner wall of the limiting groove. In this way, the limiting block is embedded in the limiting groove, which can also make the battery shell 200 more stable when it is in the first state.

[0095] In some implementations, reference Figure 1 and Figure 6 As shown, in order to enable the battery 400 to be electrically connected to the metering component 300, the water meter controller of this application may also be provided with a connecting line 600, the two ends of the connecting line 600 being connected to the metering component 300 and the battery 400 respectively, so that the metering component 300 and the battery 400 are electrically connected, and the battery 400 can supply power to the metering component 300.

[0096] refer to Figure 4 As shown, the bottom shell 100 may be provided with a wire harness groove 170, which is located between the first cavity 110 and the second cavity 210. Part of the connecting wire 600 can be snapped into the wire harness groove 170, which can fix the connecting wire 600, thereby making the connecting wire 600 more stably connected to the battery 400 and the metering component 300.

[0097] When replacing the battery 400, the connecting wire 600 can be separated from the battery 400. Due to the limiting effect of the wire harness groove 170, the other end of the connecting wire 600 can remain connected to the metering component 300 and be relatively fixed, which makes it easy to reconnect the new battery 400 to the connecting wire 600.

[0098] In some implementations, reference Figure 1 and Figure 6 As shown, the water meter controller of this application may also include multiple fasteners 700. Among the multiple fasteners 700, a portion of the fasteners 700 are detachably inserted through the upper cover 500 and the bottom shell 100 to fix the upper cover 500 and the bottom shell 100. This makes the connection between the bottom shell 100 and the upper cover 500 more stable, and when it is necessary to separate the upper cover 500 and the bottom shell 100, some of the fasteners 700 can be disassembled.

[0099] Among the multiple fasteners 700, another number of fasteners 700 are detachably inserted through the top cover 500 and the battery case 200 to fix the top cover 500 and the battery case 200, so that when the battery case 200 is in the first state, the connection between the battery case 200 and the top cover 500 is stable.

[0100] Specifically, a fixing member 700 can be installed between the battery case 200 and the top cover 500. When it is necessary to switch the battery case 200 to the second state, only one fixing member 700 needs to be removed to allow the battery case 200 to move relative to the bottom cover 100, thereby improving the efficiency of the battery case 200 switching from the first state to the second state.

[0101] The fastener 700 is secured with bolts. Correspondingly, the upper cover 500 and the bottom cover 100 have corresponding screw holes, and the upper cover 500 and the battery case 200 also have corresponding screw holes. In addition, a lead seal can be provided on the surface of the fastener 700. When the fastener 700 is disassembled, the lead seal needs to be broken to determine whether the fastener 700 has been disassembled, and thus whether the metering component 300 in the first cavity 110 of the bottom cover 100 is exposed.

[0102] A lead seal 900 can also be installed on the fastener 700 so that the user can be notified when the fastener 700 is removed.

[0103] In some implementations, reference Figure 1 , Figure 2 and Figure 6 As shown, the water meter controller of this application may also include a protective shell 800, which may be disposed within the bottom shell 100 and the first cavity 110, and the protective shell 800 partially shields the metering component 300. Adhesive may be injected into the first cavity 110 to seal the metering component 300, thereby improving the waterproof performance of the water meter controller of this application.
