Description

Technical Field

[0001] This invention relates to the field of electricity meter technology, and in particular to a three-phase intelligent multi-functional electricity meter. Background Technology

[0002] Currently, the three-phase smart multi-functional energy meter is a high-end metering device used to measure three-phase AC power, possessing multiple functions such as energy metering, data storage, remote communication, and power consumption monitoring. It can accurately record electrical parameters such as forward and reverse active energy, reactive energy, voltage, current, and power factor, and achieve data interaction with the master station system through built-in communication modules (such as RS485, carrier wave, GPRS / 4G, etc.). This energy meter is suitable for smart meter reading and energy consumption management in industrial enterprises, large commercial users, and power systems, supporting intelligent applications such as remote fee control, load control, and event logging. It is an upgraded product of traditional mechanical and electronic energy meters.

[0003] Research shows that current three-phase electricity meters are equipped with a communication module and a battery, both of which are detachable. Since the communication module enables data transmission between the electricity meter and external systems (such as the power company's main station, electricity management platform, or concentrator), it is crucial. However, the communication module frequently fails during the maintenance of three-phase electricity meters. Summary of the Invention

[0004] This invention discloses a three-phase intelligent multi-function energy meter to solve the technical problem of easy damage to the communication module during maintenance in related technologies.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A three-phase intelligent multi-functional energy meter includes: a meter body, having a wiring area, a display area, a communication compartment and a battery compartment, wherein the wiring area is located on the lower surface of the meter body, the display area is located on the upper surface of the meter body, and the communication compartment and the battery compartment are both located in the middle of the meter body;

[0007] The communication module can be plugged into and installed inside the communication compartment;

[0008] The battery body can be plugged into and installed inside the battery compartment;

[0009] A first limiting mechanism is provided inside the meter body. When installing the communication module and the battery body, the first limiting mechanism is configured to block the internal space of the battery compartment when the communication module is not installed in the communication compartment, so as to restrict the battery body from entering the battery compartment; and to automatically release the obstruction of the internal space of the battery compartment when the communication module is installed in the communication compartment, so that the battery body can be smoothly installed in the battery compartment.

[0010] A second limiting mechanism is provided inside the meter body. When the communication module and battery body are disassembled, the second limiting mechanism is configured to block the communication module inside the communication compartment when the battery body is inside the battery compartment, so as to restrict the communication module from being taken out of the communication compartment, and to automatically release the obstruction of the communication module when the battery body is taken out of the battery compartment, so that the communication module can be taken out of the communication compartment smoothly.

[0011] Optionally, a positioning hole is provided on the inner bottom wall of the communication compartment, and a positioning block is provided on the communication module. The positioning block is configured to be inserted and engaged with the positioning hole.

[0012] Optionally, the first limiting mechanism includes a moving component and a blocking component disposed within the meter body, and the moving component is configured to abut against the blocking component, wherein...

[0013] When the communication module is not installed in the communication compartment and the battery body is not installed in the battery compartment, some of the moving components are in the first position in the positioning hole, and some of the blocking components are locked to the second position to block the internal space of the battery compartment under the action of the moving components.

[0014] When the communication module is installed in the communication compartment and the positioning block is inserted into the positioning hole, some of the moving components are in a third position away from the positioning hole under the pushing action of the positioning block, and some of the blocking components move from the second position to a fourth position where they no longer block the internal space of the battery compartment under the action of the moving components.

[0015] Optionally, the moving component includes an abutment portion, a moving post, and a first spring, wherein,

[0016] The meter body has a transverse channel connected to one side of the positioning hole, and the movable column is slidably inserted into the transverse channel;

[0017] The first spring is disposed between the moving column and the inner wall of the transverse channel, and the abutting part is disposed at the end of the moving column near the positioning hole. The first spring always has the tendency to push the moving column into the positioning hole so that the abutting part is in the positioning hole. At this time, the moving component is in the first position and the blocking component is in the second position.

[0018] The abutting part is configured to slide and abut against the positioning block. During the process of the positioning block being inserted into the positioning hole, the abutting part is moved from the positioning hole into the transverse channel by the squeezing action of the positioning block. At this time, the moving component is in the first position, and the blocking component is also moved from the second position to the fourth position by the moving action of the moving component.

[0019] Optionally, the abutting part has an upwardly inclined sliding surface. When the first spring is in its natural state, a portion of the upwardly inclined sliding surface is located within the transverse channel, so that the positioning block can directly slide and abut against the upwardly inclined sliding surface during the process of entering the positioning hole.

[0020] 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 moving column, so that the moving column is subjected to the component force and moves away from the positioning hole.

[0021] Optionally, the blocking assembly includes a sliding post, a blocking portion, a guide portion, and a second spring, wherein,

[0022] The meter body has a vertical channel that is perpendicular to the horizontal channel. The sliding column is slidably disposed in the vertical channel. The upper surface of the sliding column has a slot into which the bottom end of the sliding column can be inserted.

[0023] The blocking part is provided on the side wall of the sliding column near the top, and the inner bottom wall of the battery compartment is provided with a groove for the blocking part to be inserted.

[0024] A side groove is formed on the inner wall of the vertical channel, the length direction of the side groove being consistent with the length direction of the vertical channel. A guide portion is provided on the sliding column and extends into the side groove. The first end of the second spring is connected to the inner end wall of the side groove, and the second end of the second spring is connected to the guide portion. The second spring always has a tendency to push the sliding column vertically downwards.

[0025] When the moving component is in the first position and the blocking component is in the second position, the bottom end of the sliding column is misaligned with the slot and abuts against the upper outer wall of the moving column. The blocking part is located directly above the groove and inside the battery compartment to restrict the battery body from being placed into the battery compartment.

[0026] When the moving component is in the third position and the blocking component is in the fourth position, the moving column drives the side groove to be located below the sliding column, so that the bottom end of the sliding column extends into the slot under the elastic force of the second spring, and drives the blocking part to enter the groove vertically downward from inside the battery compartment, so as to release the blocking part from the battery compartment.

[0027] Optionally, the bottom end of the sliding column has a first inclined surface, and the inner wall of the slot near the first spring has a second inclined surface, and the first inclined surface is configured to slide and abut against the second inclined surface;

[0028] The elastic force of the first spring is greater than the weight of the blocking component plus the elastic force of the second spring, so that when the communication module is taken out of the communication compartment, during the process of the moving component switching from the third position to the first position under the action of the elastic force of the first spring, the first inclined surface can move out of the slot along the second inclined surface and drive the blocking component to switch from the fourth position to the second position.

[0029] Optionally, the second limiting mechanism includes a conductive component and a limiting component installed within the meter body. The limiting component is configured to be electrically connected to the battery body via the conductive component when the battery body is installed into the battery compartment.

[0030] The limiting component can move from the inside of the meter body to the communication compartment when powered on, so as to prevent the communication module plugged into the communication compartment from being taken out of the communication compartment;

[0031] The limiting component can move from the communication compartment to the meter body when the power is off, thereby releasing the limitation on the communication module.

[0032] Optionally, the limiting component includes a reset electric cylinder and a limiting baffle; the conductive component includes a conductive sheet and a wire; and a storage chamber communicating with both the communication compartment and the battery compartment is provided on one side of the meter body located within the battery compartment. The conductive component and the limiting component are both installed within the storage chamber.

[0033] The conductive sheet is disposed at the connection between the storage chamber and the battery compartment, and after the battery body is inserted into the battery compartment, the conductive sheet is in contact with the electrode portion of the battery body;

[0034] The reset electric cylinder is electrically connected to the conductive plate via a wire. The limiting baffle is disposed on the piston rod of the reset electric cylinder, and the limiting baffle is movably located in the area where the storage chamber and the communication compartment are connected.

[0035] When the battery body is inserted into the battery compartment, the battery body is electrically connected to the reset cylinder, so that the piston rod of the reset cylinder extends and pushes part of the limiting baffle from the storage chamber into the communication compartment and above the communication module, so as to restrict the communication module from being taken out of the communication compartment.

[0036] After the battery body is removed from the battery compartment, the battery body is disconnected from the reset cylinder. The piston rod of the reset cylinder shortens under its own reset action and brings the limiting baffle back from the communication compartment to the storage chamber, thereby releasing the restriction on the communication module.

[0037] Optionally, a first cover plate is rotatably provided on the meter body and on one side of the battery compartment. The first cover plate is used to cover the battery body after it is embedded in the battery compartment.

[0038] The meter body is rotatably provided with a second cover plate on one side of the communication compartment. The second cover plate is used to cover both the communication compartment and the battery compartment at the same time to isolate them from the outside world.

[0039] The technical solution adopted in this invention can achieve the following beneficial effects:

[0040] By incorporating a first and second limiting mechanism, the installation and removal sequence of the communication module and battery can be guided at the structural level, thereby reducing the risk of damage to the communication module due to misoperation during maintenance. Specifically, the first limiting mechanism physically obstructs the internal space of the battery compartment when the communication module is not properly installed, preventing maintenance personnel from installing the battery first. Once the communication module is inserted into the compartment, the first limiting mechanism automatically releases its obstruction, allowing the battery to be inserted smoothly, thus guiding the standardized procedure of installing the communication module first and then the battery. The second limiting mechanism, by obstructing the removal of the communication module while the battery is installed, guides maintenance personnel to remove the battery before removing the communication module, preventing the communication module from being hot-swapped while energized or from sudden power loss, which could lead to module burnout or data corruption. The overall structural design possesses excellent interactive logic and user-friendliness, improving the safety of the communication module while enhancing the reliability and resistance to misoperation during the maintenance of the electricity meter, and strengthening the overall intelligence level of the machine structure.

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0055] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0056] The following is in conjunction with the appendix Figures 1 to 10 The three-phase intelligent multi-functional energy meter provided in this application will be described in detail through specific embodiments and application scenarios.

[0057] In some implementations, combined with Figures 1 to 4The three-phase smart multi-functional energy meter includes a meter body 1, which has a wiring area 11, a display area 12, a communication compartment 13, and a battery compartment 14. The wiring area 11 is located on the lower surface of the meter body 1 and is used to connect the power cable to the energy meter. The display area 12 is located on the upper surface of the meter body 1 and is used to display electrical parameters such as voltage, current, active energy, and power factor. The communication compartment 13 and the battery compartment 14 are located in the middle area of ​​the meter body 1 and are independently provided for installing the communication module 2 and the battery body 3, respectively. The communication module 2 is a functional component necessary for the energy meter to interact with external systems, including but not limited to RS485 modules, carrier modules, or GPRS / 4G wireless modules. It is installed inside the communication compartment 13 by plugging in. The battery body 3 is also installed inside the battery compartment 14 by plugging in, and is used to provide backup power for maintaining data communication and storage when the energy meter is powered off. To prevent the communication module 2 from losing power or being hot-swapped due to improper operation sequence during maintenance or replacement, which could lead to module burnout, data corruption, etc., a first limit mechanism 4 and a second limit mechanism 5 are provided inside the meter body 1. The first limit mechanism 4 and the second limit mechanism 5 are used to guide maintenance personnel to complete the operation in a preset sequence during installation and disassembly, thereby reducing the probability of misoperation.

[0058] Furthermore, the first limiting mechanism 4 is used to guide the correct sequence during installation. Its structure is configured to restrict the insertion of the battery body 3 into the battery compartment 14 when the communication module 2 has not yet been inserted into the communication compartment 13. Specifically, the first limiting mechanism 4 can be implemented using mechanical structures such as baffles, spring plates, and slide rail latches. When the communication module 2 is not in place, the mechanism is in a blocking position, and its space partially or completely occupies the entrance area of ​​the battery compartment 14, preventing the battery body 3 from being inserted into the battery compartment 14. However, when the communication module 2 is inserted into the communication compartment 13 and reaches the preset position, the structure of the communication module 2 itself or its installation action will trigger the first limiting mechanism 4 to rotate, slide, or move to a non-blocking position, thereby freeing up the entrance space of the battery compartment 14 and allowing the battery body 3 to be smoothly inserted into the battery compartment 14. Through the above structural design, in actual operation, the first limiting mechanism 4 will release the physical obstruction of the battery compartment 14 only after the communication module 2 is installed into the communication compartment 13. This guides the maintenance personnel to complete the installation of the communication module 2 first during the installation phase, and then install the battery body 3. This avoids, to a certain extent, the adverse effects on the unstable communication module 2 caused by the premature power-on of the battery body 3.

[0059] Furthermore, the second limiting mechanism 5 guides the correct operating sequence during the disassembly phase. Its structure is configured to limit the communication module 2 while the battery body 3 is still inside the battery compartment 14, thus preventing the communication module 2 from being pulled out. Specific structures may include mechanical latches, push rods, linkage rods, or electric mechanisms. When the battery body 3 is in the installed state, the limiting mechanism generates a mechanical linkage, pushing the limiting component onto the exit path of the communication module 2, forming a physical barrier to prevent the communication module 2 from being directly pulled out. Once the battery body 3 is removed from the battery compartment 14, the second limiting mechanism 5 releases its limiting state, allowing the communication module 2 to exit smoothly from the communication compartment 13. This structure guides 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 removed while energized. This reduces the risk of electrical breakdown and hot-swap damage to a certain extent, protecting the reliability and stability of the communication module 2.

[0060] It is understood that the first limiting mechanism 4 and the second limiting mechanism 5 mentioned above correspond to potential operational risks during installation and disassembly, and respectively provide structural intervention methods to guide their behavior. Specifically, the first limiting mechanism 4 makes the insertion of the battery body 3 dependent on the completion of the installation of the communication module 2, while the second limiting mechanism 5 makes the disassembly of the communication module 2 dependent on the removal of the battery body 3. Both are achieved through a mechanical linkage structure, requiring no external power supply or additional control circuitry, possessing good reliability and environmental adaptability, and suitable for equipment environments such as electricity meters that operate in a closed environment for long periods and have long maintenance cycles.

[0061] It is worth noting that, to ensure the accuracy and reliability of the aforementioned limiting mechanism, the internal structure of the meter body 1 can be modularized during the design phase, maintaining a clear assembly space relationship between the communication compartment 13, battery compartment 14, and the limiting mechanism. The communication module 2 and battery body 3 can be connected and fixed via standard clips or guide rails. The movement of the limiting mechanism is controlled by the mechanical response to changes in module position, ensuring stable structural support and recovery capability under different operating states. Furthermore, to reduce the possibility of user misjudgment, the limiting structure components can be marked with color codes, arrows, or text prompts to indicate their functions, enabling maintenance personnel to intuitively understand the required operating sequence during actual use. This enhances operational standardization to a certain extent and avoids situations where forced manipulation occurs.

[0062] In summary, this three-phase intelligent multi-functional energy meter, by incorporating a first limiting mechanism 4 to control the installation sequence of the battery body 3 and the communication module 2, and a second limiting mechanism 5 to control their disassembly sequence, structurally guides maintenance operations. This ensures that the installation and disassembly of the communication module 2 are linked to the state of the battery body 3, thereby reducing the risk of damage to the communication module 2 due to incorrect operating sequence by maintenance personnel, and improving the safety and stability of the energy meter during operation and maintenance. This solution features a compact structure, clear control logic, and requires no electrical coordination, possessing good engineering feasibility and industrialization prospects, making it particularly suitable for widespread application among various industrial and commercial power users.

[0063] In some implementations, combined with Figure 3 , Figure 5 The communication compartment 13 has a positioning hole 131 on its inner bottom wall, and the communication module 2 has a positioning block 21 configured to insert into the positioning hole 131. Specifically, the positioning block 21 can be a convex column structure, the size of which is adapted to the diameter of the positioning hole 131. During the insertion process, the positioning block 21 is inserted into the positioning hole 131, which limits the position of the communication module 2 in the vertical direction, thereby improving the guiding accuracy of the communication module 2 during the insertion process to a certain extent, so that it can be inserted into the circuit board port inside the meter body 1 more smoothly.

[0064] Meanwhile, the cooperation between the positioning block 21 and the positioning hole 131 also plays a role in stabilizing 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 maintain a relatively fixed state to a certain extent, reducing the possibility of shaking or loosening, thus contributing to maintaining 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, and then, guided, smoothly connects the communication module 2 to the circuit board. The positioning block 21 can be an integrally formed structure, rigidly connected to the body of the communication module 2. After being inserted into the positioning hole 131, it has a certain structural bending resistance to prevent the communication module 2 from tilting inside the communication compartment 13. The position of the positioning hole 131 is preset relative to the position of the circuit board inside 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 correspond spatially, thus achieving electrical connection upon completion of insertion. Through the above structural design, the installation process of communication module 2 has a mechanical limiting and guiding function, which to a certain extent helps to improve its assembly accuracy, connection reliability and structural stability in later operation.

[0065] In some implementations, such as Figures 5 to 8As shown, the first limiting mechanism 4 includes a moving component 41 and a blocking component 42 installed inside the meter body 1. The moving component 41 includes an abutment part 411, a moving column 412, and a first spring 413. The blocking component 42 includes a sliding column 421, a blocking part 422, a guide part 423, and a second spring 424. The moving component 41 and the blocking component 42 form a mechanical linkage relationship to restrict the internal space of the battery compartment 14 before the communication module 2 is installed, and to release the restriction after the communication module 2 is installed, thereby guiding maintenance personnel to complete the installation of the communication module 2 first, and then install the battery body 3.

[0066] Specifically, the inner bottom wall of the communication compartment 13 has a positioning hole 131. A transverse channel 15 is connected to one side of the positioning hole 131 inside the meter body 1. A movable column 412 is slidably disposed in the transverse channel 15. One end of the movable column 412 has an abutment part 411 for abutting against the positioning block 21, and the other end is connected to the inner wall of the transverse channel 15 by a first spring 413. The first spring 413 applies a spring force to the movable column 412 towards the positioning hole 131, causing the abutment part 411 to be inside the positioning hole 131. At this time, the movable component 41 is in the first position. Because the movable column 412 is pushed into the positioning hole 131 by the spring force in this state, it mechanically occupies part of the space of the positioning hole 131 and creates a linkage with the blocking component 42, thereby triggering the blocking component 42 to be in the second position.

[0067] Furthermore, the specific structure of the blocking component 42 is as follows: a vertical channel 16 is provided in the meter body 1, which is perpendicularly connected to the horizontal channel 15. The sliding column 421 is provided 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 moving column 412. A blocking part 422 for embedding into the groove 141 of the bottom wall of the battery compartment 14 is provided on the side wall of the sliding column 421. To control the movement of the sliding column 421 in the vertical channel 16, a side groove 161 parallel to the vertical direction is provided 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 applies a downward elastic force to the sliding column 421, pushing the sliding column 421 to move towards the bottom of the vertical channel 16, thereby driving the blocking part 422 downward from the battery compartment 14 into the slot 141.

[0068] It is understandable that in the initial state, 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 moving column 412 is kept moving towards the positioning hole 131 under the action of the first spring 413, and its abutment part 411 enters the positioning hole 131, occupying a part of the space of the positioning hole 131. At this time, the moving column 412 is in the first position, and its upper slot 4121 and the bottom end of the sliding column 421 are misaligned. The bottom end of the sliding column 421 is restricted from entering the slot 4121 and is in an upward state. The blocking part 422 is located in the middle area inside the battery compartment 14 to restrict the insertion of the battery body 3. The purpose of this structure is to guide the maintenance personnel, so that they encounter physical obstruction when performing the battery body 3 installation operation, and thus complete the installation process of the communication module 2 first.

[0069] When the 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 slides into contact with the upper inclined sliding surface 4111 on the abutment part 411. The upper inclined sliding surface 4111 is located at the front end of the abutment part 411, and its outline is an inclined surface structure that is inclined away from the transverse channel 15, for contacting the positioning block 21. Since the positioning block 21 applies downward force during the insertion process, the force on the inclined surface can be decomposed into a component force parallel to the length direction of the moving column 412 and a component force perpendicular to the direction. The parallel component force drives the moving column 412 to move away from the positioning hole 131, thereby causing the abutment part 411 to gradually withdraw from the positioning hole 131, and the moving component 41 moves from the first position to the third position.

[0070] As the movable column 412 slides, the slot 4121 above it gradually aligns with the bottom end of the sliding column 421. At this moment, the second spring 424 pushes the bottom end of the sliding column 421 into the slot 4121, and the entire sliding column 421 moves downward. The blocking part 422 at the top of the sliding column 421 moves down from inside the battery compartment 14 and embeds into the groove 141 on the bottom wall of the battery compartment 14, making the blocking part 422 part of the bottom surface of the battery compartment 14 and no longer occupying the central space of the battery compartment 14. At this time, the blocking part 422 moves into the groove 141 at the bottom of the battery compartment 14, 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 structural combination, a limit release mechanism associated with the installation action of the communication module 2 can be formed. The moving column 412 can only move under the push of the positioning block 21 when the positioning block 21 completes the insertion action into the positioning hole 131, thereby driving the blocking component 42 to move to a state where it no longer blocks the battery compartment 14, thus playing a certain role in guiding the operation sequence.

[0071] For example, the bottom end of the sliding post 421 is provided with a first inclined surface 4211, and the inner wall of the slot 4121 near the first spring 413 is provided with a second inclined surface 4122. The first inclined surface 4211 and the second inclined surface 4122 are in a sliding abutment fit relationship. The inclination direction of the first inclined surface 4211 is towards the opening direction away from the slot 4121, while the second inclined surface 4122 is set towards the direction close to the sliding post 421. The two cooperate to form a relatively inclined structure, which can provide a mutual pushing action during sliding contact.

[0072] It is understandable that after the communication module 2 and the battery body 3 are removed, the positioning block 21 disengages from the positioning hole 131, and the battery body 3 disengages from the battery compartment 14. Under the elastic force of the first spring 413, the abutment part 411 on the moving column 412 of the moving assembly 41 moves towards the positioning hole 131, causing the moving assembly 41 to transition from the third position to the first position. During this process, the first spring 413 exerts a force that pushes the moving 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 when the structure returns to its original state, so as to drive the sliding column 421 to complete the upward movement process. As the moving column 412 moves in the transverse channel 15, its top slot 4121 begins to approach the bottom of the sliding column 421. Since the bottom 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 inside the slot 4121 contacts the first inclined surface 4211 and slides against it. At this time, the pushing action of the moving column 412 generates a vertical component force through the inclined surface mating structure. This component force acts on the bottom of the sliding column 421, thereby driving the sliding column 421 to move upward along the vertical channel 16.

[0073] During the upward movement of the sliding column 421, the blocking part 422 also rises vertically from the groove 141 at the bottom of the battery compartment 14 and re-enters the central area of ​​the battery compartment 14, thus restoring the blocking state of the internal space of the battery compartment 14. That is, the blocking component 42 returns from the fourth position to the second position. This structural design forms a limiting device with automatic reset capability. When the communication module 2 and the battery body 3 are removed, the moving component 41 and the blocking component 42 return to their initial state through the inclined linkage structure, thereby providing structural protection for the correct installation sequence of the communication module 2 and the battery body 3 in the next operation.

[0074] The "first inclined surface 4211" is an inclined surface located at the bottom of the sliding post 421. Its inclination angle needs to be designed based on the depth of the slot 4121, the stroke of the moving post 412, and the elasticity conditions to ensure sufficient inclined contact area during the approach phase of the slot 4121. The "second inclined surface 4122" is an inclined structure within the slot 4121 near the first spring 413, used to form a stable sliding contact interface with the first inclined surface 4211. The mating structure between the two surfaces, through surface-to-surface sliding contact, effectively avoids structural interference and jamming risks, exhibiting good mechanical adaptability and reset guidance. In actual structural implementation, to ensure smooth sliding, the contact surfaces between the inclined surfaces can be lubricated or made of materials with a low coefficient of friction, such as wear-resistant polymer plastics.

[0075] This embodiment further refines the structural relationship between the moving component 41 and the blocking component 42. The inclined contact cooperation forms an upward driving force to pull the sliding column 421 out of the slot 4121, thereby automatically restoring it to the initial limit state after the structure is removed. This is beneficial to improving the closed-loop stability of the overall limit mechanism, and to a certain extent enhances the reliability of the energy meter in the process of multiple maintenance and disassembly. It also ensures that the installation sequence of the communication module 2 and the battery body 3 is continuously and effectively guided by the structure, reducing the risk of damage caused by incorrect operation sequence.

[0076] Through the mechanical linkage structure between the moving component 41 and the blocking component 42, this embodiment introduces a limiting mechanism with behavioral guidance function into the structure of the electricity meter. To a certain extent, it guides maintenance personnel to complete the disassembly and assembly of the communication module 2 and the battery body 3 in a predetermined order. This helps to reduce the probability of communication module 2 failure, data disorder, or device burnout caused by incorrect installation sequence. At the same time, the structure relies on springs and mechanical contact to complete the installation, disassembly, and reset processes. It does not depend on power supply, control circuit, or sensing devices. It has the characteristics of simple structure, clear action, long-term stability, and easy maintenance. It is suitable for various electricity meter usage scenarios with high requirements for communication reliability and maintenance standardization.

[0077] In some implementations, combined with 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. 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. When the battery body 3 is removed, it is in a powered-off state and releases the restriction on the disassembly of the communication module 2.

[0078] Furthermore, the limiting component 52 includes a reset cylinder 521 and a limiting baffle 522, and the conductive component 51 includes a conductive sheet 511 and a wire 512. A storage chamber 17 is provided inside the meter body 1, positioned between the battery compartment 14 and the communication compartment 13, and communicating with both to form a space for accommodating the limiting component 52 and the conductive component 51. The conductive sheet 511 is disposed at the connection point between the storage chamber 17 and the battery compartment 14, and is used to abut against the electrode portion of the battery body 3, thereby achieving electrical connection after the battery body 3 is inserted into the battery compartment 14. The reset cylinder 521 is connected to the conductive sheet 511 via the wire 512, forming a complete circuit path 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, located in the communication area between the storage chamber 17 and the communication compartment 13, and can reciprocate under the drive of the reset cylinder 521.

[0079] Understandably, in actual use, when a 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 plate 511. The conductive plate 511 transmits current through the wire 512 to the reset cylinder 521, thereby driving the reset cylinder 521 into an energized state. In the energized state, the piston rod of the reset cylinder 521 will extend outward, driving the limiting baffle 522 from the storage chamber 17 into the communication compartment 13. The limiting baffle 522 is located above or to the side of the communication module 2, physically blocking the direction of removal of the communication module 2. This structural arrangement ensures that when the battery body 3 is installed, the communication module 2 is restricted by the limiting baffle 522 and cannot be removed, structurally preventing maintenance personnel from removing the communication module 2 first.

[0080] When maintenance requires the disassembly of communication module 2 and battery body 3, the second limiting mechanism 5 will act as a sequential guide. Due to the presence of the limiting baffle 522, communication module 2 cannot be removed while battery body 3 is still installed. Therefore, the maintenance operation can only begin by pulling battery body 3 out of battery compartment 14. Simultaneously with the removal of battery body 3, the electrode portion separates from the conductive sheet 511, the current path is cut off, the reset cylinder 521 is de-energized, and its internal reset structure drives the piston rod to retract. The limiting baffle 522 also retracts from communication compartment 13 into storage chamber 17, thereby releasing the limiting effect on communication module 2. Only in this state can communication module 2 be normally removed. It should be noted that the reset cylinder 521 is prior art well known to those skilled in the art, and its reset principle will not be described in detail here.

[0081] Based on this, the design of the second limiting mechanism 5 utilizes the logical linkage between the electrical connection state and the mechanical limiting action to construct a mechanism for limiting the communication module 2 based on the battery on / off state. Since the reset cylinder 521 uses a low-power design and is not a continuous motor, but only needs to act once at the moment the battery is connected or disconnected, the overall power consumption is extremely low and will not affect the core metering and data processing functions of the energy meter. The current consumption of the reset cylinder 521 during operation can be controlled below the microampere level, and its drive stroke is small and its action is fast, making it suitable for installation inside small energy meters.

[0082] In terms of structural terminology, "conductive sheet 511" refers to a metal sheet with an elastic or elastic support structure. Its material is usually copper alloy or silver-plated steel sheet, which has good conductivity and corrosion resistance and is suitable for forming a contact and conductive relationship with battery electrodes. "Reset cylinder 521" is a linear drive component that can extend the piston rod after being energized and retract the piston rod through a built-in reset spring or memory material after being de-energized. It has good integration adaptability in electronic devices with limited space. "Limiting baffle 522" is a planar structural component of moderate size. Its structure is orthogonal to the insertion and removal direction of the communication module 2. It can be moved forward into the space of the communication compartment 13 to restrict the communication module 2.

[0083] This embodiment combines electrical connections with structural constraint actions to establish a reset limit mechanism with disassembly / reassembly sequence constraint function. This can standardize the maintenance operation process to a certain extent, and enable sequential logical control of the operation sequence of communication module 2 during disassembly. This helps reduce the risk of communication module 2 failure caused by hot-swapping or operation under power failure conditions, and also improves the overall maintainability and structural intelligence of the electricity meter to a certain extent. Through the setting of this structure, the second limit mechanism 5 has automatic control and structural feedback functions, forming a reusable, logically clear, and structurally compact communication module 2 disassembly / reassembly sequence guidance system.

[0084] In some implementations, combined with Figure 1 , Figure 2 A first cover plate 18 is rotatably provided on the meter body 1 and on one side of the battery compartment 14. The first cover plate 18 is used to cover the battery body 3 after it is embedded in the battery compartment 14. Furthermore, a second cover plate 19 is rotatably provided on the meter body 1 on one side of the communication compartment 13. The second cover plate 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.
