[0002] The three-phase intelligent multifunctional energy meter is a high-end device for measuring three-phase AC power. It offers multiple functions, including energy metering, data storage, remote communication, and power consumption monitoring. It accurately records electrical parameters such as forward and reverse active energy, reactive energy, voltage, current, and power factor, and interacts with the master station system via built-in communication modules (such as RS485, carrier, and GPRS / 4G). This energy meter is suitable for intelligent meter reading and energy management in industrial enterprises, large commercial users, and power systems. It supports intelligent applications such as remote cost control, load control, and event logging, representing an upgrade to traditional mechanical and electronic energy meters.

[0003] Research has shown that three-phase electricity meters currently include a removable communication module and battery. The communication module is crucial because it enables data transmission between the meter and external systems (such as the power company's main station, power management platform, or concentrator). However, damage to the communication module is common during maintenance of three-phase meters. Summary of the Invention

[0007] Optionally, the first limiting mechanism includes a moving component and a blocking component provided in the meter body, and the moving component is configured to abut and cooperate with the blocking component, wherein, When the communication module is not installed in the communication compartment and the battery body is not installed in the battery compartment, part of the movable assembly is in the first position in the positioning hole, and part of the blocking assembly is locked to the second position to block the internal space of the battery compartment under the action of the movable assembly; When the communication module is installed in the communication compartment and the positioning block is inserted into the positioning hole, part of the movable component is in the third position away from the positioning hole under the pushing action of the positioning block, and part of the blocking component is moved from the second position to the fourth position no longer blocking the internal space of the battery compartment under the action of the movable component.

[0008] Optionally, the moving assembly includes an abutment portion, a moving column and a first spring, wherein: A transverse channel is provided in the electric meter body on one side of the positioning hole, and the movable column is slidably inserted into the transverse channel; The first spring is disposed between the movable column and the inner wall of the transverse channel, and the abutment portion is disposed at one end of the movable column close to the positioning hole. The first spring always tends to push the movable column into the positioning hole so that the abutment portion is located in the positioning hole. At this time, the movable component is in the first position and the blocking component is in the second position. The abutment portion is configured to be in sliding abutment engagement with the positioning block. During the process of inserting the positioning block into the positioning hole, the abutment portion is squeezed by the positioning block and moves from the positioning hole into the transverse channel.

[0009] Optionally, the abutment portion has an upper inclined sliding surface, and when the first spring is in a natural state, a portion of the upper inclined sliding surface is located in the transverse channel, so that the positioning block can directly slide and abut against the upper inclined sliding surface when entering the positioning hole; When the positioning block slides against the upper inclined sliding surface, the thrust applied by the positioning block to the upper inclined sliding surface can be decomposed into a component force parallel to the length direction of the movable column, so that the movable column is moved away from the positioning hole by the component force.

[0011] Optionally, the bottom end of the sliding column has a first inclined surface, the inner side wall of the slot close to the first spring is a second inclined surface, and the first inclined surface is configured to slide and abut against the second inclined surface; The elastic force of the first spring is greater than the gravity of the blocking assembly plus the elastic force of the second spring, so that when the communication module is taken out of the communication compartment, the moving assembly switches from the third position to the first position under the action of the elastic force of the first spring. The first inclined surface can be moved out of the slot along the second inclined surface and drive the blocking assembly to switch from the fourth position to the second position.

[0014] Optionally, a first cover is rotatably provided on the electric meter body and on one side of the battery compartment, and the first cover is used to shield the battery body after the battery body is inserted into the battery compartment; A second cover is rotatably provided on one side of the communication compartment of the electric meter body.

Specifically, the first limiting mechanism forms a physical block to the internal space of the battery compartment when the communication module is not installed in place, avoiding the operation of the maintenance personnel to install the battery body first; after the communication module is inserted into the communication compartment, the first limiting mechanism automatically removes the block to the battery compartment, so that the battery body can be smoothly inserted, thereby guiding the standard operation process of installing the communication module first and then installing the battery body. The second limiting mechanism guides the maintenance personnel to remove the battery body first before removing the communication module by forming a disassembly block to the communication module in the battery body installation state, avoiding the hot plug or sudden power failure of the communication module in the live state, thereby causing the risk of module burning or data disorder. The overall structural design has good interactive logic and operation friendliness, which improves the safety of the communication module, improves the reliability and anti-misoperation ability during the maintenance process of the electric energy meter, and enhances the intelligent level of the overall structure.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0020] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0021] The following is combined with Figures 1 to 10 , the three-phase intelligent multifunctional electricity meter provided in this application is described in detail through specific embodiments and application scenarios.

[0022] In some embodiments, combined Figures 1 to 4The three-phase intelligent multifunctional electric energy meter comprises an electric meter body 1, the electric meter body 1 having a wiring area 11, a display area 12, a communication compartment 13 and a battery compartment 14, wherein the wiring area 11 is arranged on the lower surface of the electric meter body 1 for realizing the access connection of the power cable and the electric energy meter, the display area 12 is arranged on the upper surface of the electric meter body 1 for displaying the electric parameters such as voltage, current, active electric energy and power factor, and the communication compartment 13 and the battery compartment 14 are arranged in the middle area of the electric meter body 1 and are independently arranged, and are respectively used for mounting a communication module 2 and a battery body 3. The communication module 2 is a functional component necessary for realizing the data interaction between the electric energy meter and the external system, including but not limited to an RS485 module, a carrier wave module or a GPRS / 4G wireless module, etc., which is mounted in the communication compartment 13 through a plug-in mode, and the battery body 3 is also mounted in the battery compartment 14 through a plug-in mode, and is used for providing a standby power supply for maintaining the data communication and storage of the electric energy meter in the power-off state. In order to avoid the problems such as module burning and data disorder caused by the power loss or hot plug of the communication module 2 due to improper operation sequence in the maintenance or replacement process, a first limiting mechanism 4 and a second limiting mechanism 5 are arranged in the electric meter body 1, and the first limiting mechanism 4 and the second limiting mechanism 5 are respectively used for guiding the maintenance personnel to complete the operation according to the preset sequence in the installation and disassembly process, so as to reduce the probability of misoperation.

[0023] Further, the first limiting mechanism 4 is used for guiding the correct sequence in the installation stage, and the structure thereof is configured to limit the insertion of the battery body 3 into the battery compartment 14 when the communication module 2 has not been plugged and mounted in the communication compartment 13. Specifically, the first limiting mechanism 4 can adopt mechanical structures such as a baffle, a spring sheet, a sliding rail buckle, etc., and in the state that the communication module 2 is not in place, the mechanism is in a blocking position, and the space part or the whole occupies the entrance area of the battery compartment 14, so that the battery body 3 cannot be inserted into the battery compartment 14; and when the communication module 2 is plugged into the communication compartment 13 and reaches the preset position, the structure of the communication module 2 itself or the installation action thereof will trigger the first limiting mechanism 4 to rotate, slide or move to the non-blocking position, so as to leave the entrance space of the battery compartment 14, and enable the battery body 3 to be smoothly inserted into the battery compartment 14. Through the above structural design, the maintenance personnel can only install the communication module 2 into the communication compartment 13 in the actual operation, and the first limiting mechanism 4 will be released from the physical blocking of the battery compartment 14, so as to guide the maintenance personnel to preferentially complete the installation action of the communication module 2 in the installation stage, and then install the battery body 3, thereby avoiding the adverse effects on the unstable communication module 2 caused by the pre-power-on of the battery body 3 to a certain extent.

[0024] Furthermore, the second limiting mechanism 5 is used to guide the correct operating sequence during the disassembly phase. Its structure is configured to limit the communication module 2 when the battery body 3 is still in the battery compartment 14, thereby preventing the communication module 2 from being pulled out. The specific structure may include a mechanical snap, a push rod, a linkage rod, an electric motor, etc. The limiting mechanism generates a mechanical linkage when the battery body 3 is in the installed state, pushing the limiting member onto the exit path of the communication module 2, forming a physical blocking structure to prevent the communication module 2 from being directly pulled out; and when the battery body 3 is removed from the battery compartment 14, the second limiting mechanism 5 is released from the limiting state, so that the exit path of the communication module 2 is released, and the maintenance personnel can smoothly pull the communication module 2 out of the communication compartment 13. This structure can guide maintenance personnel to remove the battery body 3 from the battery compartment 14 before disassembling the communication module 2, preventing the communication module 2 from being directly unplugged while it is powered, to a certain extent reducing the risks of electrical breakdown, hot plug damage, etc., and protecting the reliability and stability of the communication module 2.

[0025] It can be understood that the first and second limiting mechanisms 4, 5 respectively address potential misoperation risks during installation and removal, and provide structural interventions to guide their behavior. The first limiting mechanism 4 makes the insertion of the battery body 3 dependent on the installation status of the communication module 2, while the second limiting mechanism 5 makes the removal of the communication module 2 dependent on the removal status of the battery body 3. Both mechanisms are implemented through a mechanical linkage structure, requiring no external power supply or additional control circuitry. They offer excellent reliability and environmental adaptability, making them suitable for equipment such as electricity meters, which operate in a closed environment for long periods of time and have long maintenance cycles.

[0026] It is worth noting that in order to ensure the accuracy and reliability of the action of the above-mentioned limiting mechanism, the internal structure of the meter body 1 can be modularly planned during the design process, so that a clear assembly space relationship is maintained between the communication compartment 13, the battery compartment 14 and the limiting mechanism. The communication module 2 and the battery body 3 can be plugged and fixed by standard clips or guide rails, and the action of the limiting mechanism is controlled by the mechanical response to the change in module position, ensuring stable structural support and recovery capabilities under different action states. In addition, in order to reduce the possibility of user misjudgment, the limiting structural components can be marked with color, arrows or text prompts for function, so that maintenance personnel can intuitively understand the operating sequence requirements in actual use, thereby enhancing the standardization of operations to a certain extent and avoiding the occurrence of forced pulling.

[0027] In summary, this three-phase intelligent multifunctional energy meter, by providing a first limiting mechanism 4 for controlling the installation sequence of the battery body 3 and the communication module 2, and a second limiting mechanism 5 for controlling their removal sequence, structurally guides maintenance operations, ensuring that both the installation and removal of the communication module 2 are linked to the status of the battery body 3. This, to a certain extent, reduces the risk of damage to the communication module 2 due to incorrect operation sequences by maintenance personnel, thereby improving the safety and stability of the energy meter during operation and maintenance. This solution has a compact structure, clear control logic, and no electrical coordination required. It has good engineering feasibility and industrial prospects, making it particularly suitable for promotion and application among various industrial and commercial power users.

[0028] In some embodiments, combined Figure 3 、 Figure 5 A positioning hole 131 is formed on the inner bottom wall of the communication compartment 13, and a positioning block 21 is provided on the communication module 2. The positioning block 21 is configured to plug and mate with the positioning hole 131. Specifically, the positioning block 21 can be a convex columnar structure, and its size is adapted to the aperture of the positioning hole 131. During the plugging process, the positioning block 21 is inserted into the positioning hole 131 to define the position of the communication module 2 in the vertical direction, thereby improving the guiding accuracy of the communication module 2 during the plug-in process to a certain extent, allowing it to plug and mate more smoothly with the circuit board port inside the meter body 1.

[0029] At the same time, the cooperation between the positioning block 21 and the positioning hole 131 also stabilizes the installation of the communication module 2. Even when the energy meter is subjected to external mechanical vibration or thermal expansion and contraction caused by temperature changes, the communication module 2 can still be relatively fixed to a certain extent, reducing the possibility of its shaking or loosening, thereby helping to maintain the reliability of the electrical connection. To ensure smooth alignment of the positioning block 21 during insertion, when the communication module 2 approaches the bottom wall of the communication compartment 13, the positioning block 21 at its front end first enters the positioning hole 131, thereby guiding the smooth insertion of the communication module 2 and the circuit board. The positioning block 21 can be an integrally molded structure, rigidly connected to the body of the communication module 2. After insertion into the positioning hole 131, it has a certain degree of structural bending resistance, preventing the communication module 2 from deflecting within the communication compartment 13. The positioning hole 131 is preset relative to the position of the circuit board within the meter body 1, so that when the positioning block 21 is inserted into the positioning hole 131, the electrical connection terminals on the communication module 2 and the circuit board ports can be spatially aligned, thereby achieving electrical connection upon completion of insertion. Through the above structural design, the installation process of the communication module 2 has a mechanical limit guide function, which is beneficial to improving its assembly accuracy, connection reliability and structural stability in subsequent operation to a certain extent.

[0030] In some embodiments, Figures 5 to 8As shown, the first limiting mechanism 4 includes a moving assembly 41 and a blocking assembly 42 installed inside the electric meter body 1. The moving assembly 41 includes an abutment portion 411, a moving post 412, and a first spring 413, while the blocking assembly 42 includes a sliding post 421, a blocking portion 422, a guide portion 423, and a second spring 424. A mechanical linkage is formed between the moving assembly 41 and the blocking assembly 42 to restrict the internal space of the battery compartment 14 before the communication module 2 is installed, and to remove the restriction after the communication module 2 is installed, thereby guiding maintenance personnel to complete the installation of the communication module 2 first before installing the battery body 3.

[0031] Specifically, a positioning hole 131 is formed on the inner bottom wall of the communication compartment 13. A transverse channel 15 is provided on one side of the positioning hole 131 within the electric meter body 1. A movable post 412 is slidably disposed within the transverse channel 15. One end of the movable post 412 is provided with an abutment portion 411 for abutting the positioning block 21. The other end is connected to the inner wall of the transverse channel 15 via a first spring 413. The first spring 413 applies an elastic force toward the positioning hole 131 to the movable post 412, causing the abutment portion 411 to be located within the positioning hole 131. At this time, the movable assembly 41 is in the first position. Since the movable post 412 is elastically pushed into the positioning hole 131 in this state, it mechanically occupies a portion of the space in the positioning hole 131 and forms a linkage relationship with the blocking assembly 42, thereby triggering the blocking assembly 42 to be in the second position.

[0032] Furthermore, the specific structure of the blocking assembly 42 is as follows: a vertical channel 16 is opened in the meter body 1 and is vertically connected to the horizontal channel 15. The sliding column 421 is arranged in the vertical channel 16 in a vertical sliding manner. The lower end of the sliding column 421 can be aligned with the slot 4121 opened above the movable column 412. The side wall of the sliding column 421 is provided with a blocking portion 422 for embedding in the inner bottom wall groove 141 of the battery compartment 14. In order to control the movement state of the sliding column 421 in the vertical channel 16, a side groove 161 parallel to the vertical direction is opened in the side wall of the vertical channel 16. The guide part 423 is fixed to the outer surface of the sliding column 421 and extends into the side groove 161. One end of the guide part 423 is connected to the second spring 424, and the other end of the second spring 424 is fixed to the inner end wall of the side groove 161. The second spring 424 exerts a downward elastic force on the sliding column 421, pushing the sliding column 421 to move toward the bottom of the vertical channel 16, thereby driving the blocking part 422 downward from the battery compartment 14 into the embedded groove 141.

[0033] It can be understood that in the initial state, that is, when the communication module 2 is not installed in the communication compartment 13 and the battery body 3 is not inserted into the battery compartment 14, the movable column 412 continues to move toward the positioning hole 131 under the action of the first spring 413, and its abutment portion 411 enters the positioning hole 131, occupying a portion of the space in the positioning hole 131. At this time, the movable column 412 is in the first position, and its upper slot 4121 is misaligned with the bottom end of the sliding column 421. The bottom end of the sliding column 421 is restricted from entering the slot 4121 and is in a floating state. The blocking portion 422 is located in the middle area inside the battery compartment 14, which is used to limit the insertion of the battery body 3. The purpose of this structural state is to guide maintenance personnel, so that when performing the battery body 3 installation operation, they encounter physical obstacles, so that they can complete the installation process of the communication module 2 first.

[0034] When maintenance personnel insert the communication module 2 into the communication compartment 13, the positioning block 21 on the communication module 2 enters the positioning hole 131. During the insertion process, the positioning block 21 comes into sliding contact with the upper inclined surface 4111 on the abutting portion 411. The upper inclined surface 4111 is provided at the front end of the abutting portion 411 and has a profile that is inclined away from the transverse channel 15 and is used to contact the positioning block 21. Because the positioning block 21 applies a downward force during the insertion process, the force acting on the inclined surface can be decomposed into a component parallel to the length of the movable column 412 and a component perpendicular to the length. The parallel component drives the movable column 412 to move away from the positioning hole 131, thereby causing the abutting portion 411 to gradually withdraw from the positioning hole 131, and the movable assembly 41 moves from the first position to the third position.

[0035] As the movable post 412 slides, the slot 4121 above it gradually aligns with the bottom end of the sliding post 421. At this moment, the second spring 424 pushes the bottom end of the sliding post 421 into the slot 4121, causing the entire sliding post 421 to move downward. The blocking portion 422 at the top of the sliding post 421 moves downward from the battery compartment 14 and embeds into the embedded groove 141 on the bottom wall of the battery compartment 14, making the blocking portion 422 become part of the bottom surface of the battery compartment 14 and no longer occupying the space in the middle of the battery compartment 14. At this point, the blocking portion 422 moves into the embedded groove 141 at the bottom of the battery compartment 14, and the blocking assembly 42 is in the fourth position. The battery compartment 14 is restored to an unobstructed state, and maintenance personnel can smoothly insert the battery body 3 into the battery compartment 14. Through the above-mentioned structural combination, a limit release mechanism associated with the installation action of the communication module 2 can be formed. When and only when the positioning block 21 completes the insertion action of the positioning hole 131, the movable column 412 can move under the push of the positioning block 21, thereby driving the blocking component 42 to transfer to a state where it no longer blocks the battery compartment 14, playing a certain role in guiding the operation sequence.

[0036] For example, a first inclined surface 4211 is provided at the bottom end of the sliding post 421, and a second inclined surface 4122 is provided on the inner wall of the slot 4121 near the first spring 413. The first inclined surface 4211 and the second inclined surface 4122 are in a sliding engagement relationship. The first inclined surface 4211 is inclined away from the opening of the slot 4121, while the second inclined surface 4122 is positioned toward the sliding post 421. The two surfaces cooperate to form a relatively inclined structure, which provides a mutual pushing effect during sliding contact.

[0037] It is understood that after the communication module 2 and the battery body 3 are removed, the positioning block 21 is disengaged from the positioning hole 131, and the battery body 3 is disengaged from the battery compartment 14. Under the elastic force of the first spring 413, the abutment portion 411 on the movable column 412 in the movable assembly 41 moves toward the positioning hole 131, causing the movable assembly 41 to transition from the third position to the first position. During this process, the first spring 413 has a force that pushes the movable column 412, and its elastic force is set to be greater than the sum of the overall weight of the blocking assembly 42 and the elastic force of the second spring 424. This setting is used to provide sufficient driving force to drive the sliding column 421 to complete the upward movement process when the structure returns to its original state. As the moving column 412 moves in the horizontal channel 15, its top slot 4121 begins to approach the bottom end of the sliding column 421. Since the bottom end of the sliding column 421 has a first inclined surface 4211, when the slot 4121 approaches the sliding column 421, the second inclined surface 4122 in the slot 4121 contacts and slides against the first inclined surface 4211. At this time, the propulsion action of the moving column 412 generates a vertical component force through the inclined surface matching structure. This component force acts on the bottom end of the sliding column 421, thereby driving the sliding column 421 to move upward along the vertical channel 16.

[0038] As the sliding post 421 moves upward, the blocking portion 422 also rises vertically from the recess 141 at the bottom of the battery compartment 14 and re-enters the central area of ​​the battery compartment 14, re-blocking the interior of the battery compartment 14. This restores the blocking assembly 42 from the fourth position to the second position. This structural design forms a limiter with automatic reset capability. When the communication module 2 and battery body 3 are removed, the inclined linkage between the moving assembly 41 and the blocking assembly 42 returns to its initial state, thus providing structural assurance for the correct installation sequence of the communication module 2 and battery body 3 the next time.

[0039] Among them, the "first inclined surface 4211" is an inclined surface provided at the bottom end of the sliding column 421, and its inclination angle needs to be designed according to the depth of the slot 4121, the stroke of the moving column 412 and the elastic force conditions, so that it can form a sufficient inclined surface contact area when the slot 4121 approaches; the "second inclined surface 4122" is an inclined surface structure on the side of the slot 4121 close to the first spring 413, which is used to form a stable sliding contact interface with the first inclined surface 4211. The matching structure between the two can effectively avoid structural interference and the risk of jamming through surface-to-surface sliding contact, and has good mechanical adaptability and reset guidance. In the actual structural implementation, in order to ensure smooth sliding, the contact surface between the inclined surfaces can be lubricated, or made of a material with a low friction coefficient, such as a polymer wear-resistant plastic.

[0040] This embodiment further refines the structural relationship between the moving component 41 and the blocking component 42, and forms an upward driving force for withdrawing the sliding column 421 from the slot 4121 through the contact cooperation of the inclined surfaces, and then automatically restores to the initial limit state after the structure is dismantled, which is beneficial to improving the closed-loop stability of the overall limit mechanism, and to a certain extent enhances the reliability of the electric energy meter during multiple maintenance and disassembly processes, ensures that the installation sequence of the communication module 2 and the battery body 3 is continuously and effectively guided by the structure, and reduces the risk of damage caused by incorrect operation sequence.

[0041] Through the mechanical linkage structure between the above-mentioned moving component 41 and the blocking component 42, this embodiment introduces a limit mechanism with a behavior guidance function in the electric energy meter structure, which guides maintenance personnel to complete the disassembly and assembly operations of the communication module 2 and the battery body 3 in a predetermined order to a certain extent, which is beneficial to reducing the probability of failure of the communication module 2, data disorder or device burning due to incorrect installation sequence. At the same time, the structure relies on springs and mechanical contact during the installation, disassembly and reset processes, and does not rely on power supply, control circuit or sensing device. It has the characteristics of simple structure, clear action, long-term stability and easy maintenance, and is suitable for various electric energy meter usage scenarios with high requirements on communication reliability and maintenance standardization.

[0042] In some embodiments, combined Figure 3 、 Figure 9 and Figure 10 The second limiting mechanism 5 includes a conductive component 51 and a limiting component 52 installed in the meter body 1, wherein the limiting component 52 is in a powered state when the battery body 3 is installed and restricts the disassembly of the communication module 2, and is in a powered-off state when the battery body 3 is removed and releases the restriction on the disassembly of the communication module 2.

[0043] Furthermore, the limiting assembly 52 includes a reset cylinder 521 and a limiting baffle 522, while the conductive assembly 51 includes a conductive plate 511 and a wire 512. A storage chamber 17 is provided within the meter body 1. This storage chamber 17 is positioned between the battery compartment 14 and the communication compartment 13 and communicates with both, forming a space for accommodating the limiting assembly 52 and the conductive assembly 51. The conductive plate 511 is positioned at the junction between the storage chamber 17 and the battery compartment 14, and is designed to engage with the electrodes of the battery body 3, thereby achieving an electrical connection when the battery body 3 is inserted into the battery compartment 14. The reset cylinder 521 is connected to the conductive plate 511 via a wire 512, forming a complete electrical circuit from the battery body 3 to the reset cylinder 521. The limiting baffle 522 is mounted on the piston rod of the reset cylinder 521. It is located in the area connecting the storage chamber 17 and the communication compartment 13 and can move back and forth under the drive of the reset cylinder 521.

[0044] It is understandable that during actual use, after the maintenance personnel insert the communication module 2 into the communication compartment 13 and then insert the battery body 3 into the battery compartment 14, the electrode portion of the battery body 3 will automatically adhere to the conductive sheet 511, and the conductive sheet 511 will transmit the current to the reset cylinder 521 through the wire 512, thereby driving the reset cylinder 521 to be in the power-on state. In the power-on state, the piston rod of the reset cylinder 521 will extend outward and drive the limit baffle 522 from the storage chamber 17 to the inside of the communication compartment 13. The limit baffle 522 is located above or to the side of the communication module 2, forming a physical block to the removal direction of the communication module 2. This structural coordination ensures that when the battery body 3 is installed, the communication module 2 is restricted by the limit baffle 522 and cannot be removed, thereby structurally preventing the maintenance personnel from preferentially removing the communication module 2.

[0045] When maintenance requires the disassembly of the communication module 2 and the battery body 3, the second limiting mechanism 5 will play a sequential guiding role. Due to the presence of the limiting baffle 522, the communication module 2 cannot be removed when the battery body 3 is still in the installed state, so the maintenance operation can only be carried out by pulling the battery body 3 out of the battery compartment 14 first. At the same time as the battery body 3 is removed, the electrode part is separated from the conductive sheet 511, the current path is cut off, the reset cylinder 521 is powered off, and the reset structure inside it drives the piston rod to retract, and the limiting baffle 522 is also withdrawn from the communication compartment 13 to the storage chamber 17, thereby releasing the limiting effect on the communication module 2. In this state, the communication module 2 can be taken out normally. It should be noted that the reset cylinder 521 is a prior art well known to those skilled in the art, and its reset principle will not be elaborated in detail here.

[0046] Based on this, the design of the second limit mechanism 5 utilizes a logical linkage between the electrical connection status and the mechanical limit action, creating a mechanism that controls the communication module 2's limit based on the battery's on / off status. Because the reset cylinder 521 utilizes a low-power design and is not a continuous motor, but rather operates once at the instant the battery is connected or disconnected, overall power consumption is extremely low, without impacting the meter's core metering and data processing functions. The reset cylinder 521's operating current consumption is controlled below the microampere level, and its short drive stroke and fast action make it suitable for installation within the cavity of small meters.

[0047] In terms of structural terminology, "conductive sheet 511" refers to a metal sheet with an elastic or elastic support structure, the material of which is usually copper alloy or silver-plated steel sheet, with good conductivity and corrosion resistance, and is suitable for forming a contact and conduction relationship with the battery electrode; "reset electric cylinder 521" is a linear drive component that can extend the piston rod when powered on, and drive the piston rod to retract through a built-in reset spring or memory material after power is off. It has good integration adaptability in electronic equipment with limited space; "limit baffle 522" is a planar structural component of moderate size, which is structurally orthogonal to the plug-in and unplugging direction of the communication module 2, and can achieve restriction on the communication module 2 by moving forward into the space of the communication compartment 13.

[0048] This embodiment combines electrical connections with structural limiting actions to create a reset limiter mechanism that constrains assembly and disassembly sequences. This standardizes maintenance procedures to a certain extent, providing logical sequential control of the communication module 2's operational sequence during disassembly. This reduces the risk of communication module 2 failure due to hot plugging or power failure, while also improving the overall maintainability and intelligent structure of the electricity meter. This structure provides the second limiter 5 with automatic control and structural feedback, creating a reusable, logically clear, and compact communication module 2 assembly and disassembly sequence guidance system.

[0049] In some embodiments, combined Figure 1 、 Figure 2 A first cover 18 is rotatably provided on the meter body 1 and on one side of the battery compartment 14. The first cover 18 is used to cover the battery body 3 after the battery body 3 is embedded in the battery compartment 14. Furthermore, a second cover 19 is rotatably provided on the meter body 1 on one side of the communication compartment 13. The second cover 19 is used to cover the communication compartment 13 and the battery compartment 14 at the same time to isolate them from the outside world and prevent dust or external impurities from entering the communication compartment 13 or the battery compartment 14.
