Abstract
Description
Technical Field
[0001] This application relates to the field of smart energy meter manufacturing technology, and in particular to a smart energy meter with an anti-vibration steady-state integrated battery module structure. Background Technology
[0002] Currently, with the continuous development of smart grids, remote meter reading, and IoT communication technologies, smart meters are gradually evolving from traditional single metering devices into integrated terminal devices that combine metering, data acquisition, remote communication, status monitoring, and edge control. Modern smart meters typically integrate a main control circuit, metering chip, communication module, and auxiliary power supply module. To ensure that communication functions can continue operating under conditions of external power failure, short-term power outages, or specific low-power scenarios, some smart meters typically have an independent battery module. This independent battery module enables functions such as fault reporting, event logging, data retention, and emergency communication.
[0003] Currently, the battery module in existing smart meters typically includes an independent battery compartment structure housed within the meter casing and a detachable battery located within the compartment. This means a dedicated space is reserved inside the meter casing, and the battery is secured and electrically connected via clips, springs, screws, or plug-in terminals. In some structures, the battery conducts electricity by contacting its positive and negative terminals with metal elastic contacts; others use wire soldering to connect the battery to the communication module to improve conductivity stability. Furthermore, to facilitate future battery replacement, some meters also feature an openable battery compartment cover on the side of the casing, allowing for battery removal and maintenance.
[0004] In practical applications, the battery compartments in smart meters are mostly located on the side, back, or inside of the meter. During maintenance, operators typically need to reach into the narrow installation space to perform disassembly and assembly. However, since smart meters are mostly centrally installed with small gaps between adjacent meters, and the distribution box contains numerous wires, circuit breakers, and mounting brackets, especially since some batteries need to be pulled out as a whole along a fixed direction, it's difficult for operators to apply effective force when there are obstructions. This leads to difficulties in disassembly and assembly, low maintenance efficiency, and an increased risk of accidentally touching other electrical components. Furthermore, to ensure installation stability, some existing technologies add locking mechanisms or screws, but this further increases the complexity of disassembly during later maintenance and battery replacement. This makes it difficult for existing technologies to simultaneously meet the requirements of vibration-resistant and stable battery installation and convenient disassembly and assembly in confined spaces. Summary of the Invention
[0005] This application provides a smart energy meter with an integrated battery module structure for vibration resistance and steady-state operation. This smart energy meter enables quick installation and removal of the battery in narrow installation environments, while also ensuring vibration-resistant and stable installation, reliable conduction, and convenient maintenance. It not only avoids the risk of reverse connection caused by incorrect battery installation, but also reduces manual identification and adjustment steps under limited operating space conditions, thereby improving on-site maintenance efficiency.
[0006] This application provides a smart energy meter with an anti-vibration steady-state integrated battery module structure, which adopts the following technical solution: A smart energy meter with an anti-vibration and steady-state integrated battery module structure includes: an energy meter body, wherein the energy meter body is provided with a communication compartment and a battery cavity, and the battery cavity is provided with an installation port for replacing the battery; A quick-connect battery mechanism includes a clamping bolt, a sliding seat, a locking block, and a conductive component. The clamping bolt is slidably disposed within the battery cavity and has a through-hole on it. The sliding seat is slidably disposed within the mounting slot, and the locking block is rotatably disposed within the mounting slot. A linkage drive structure for driving the locking block to flip is provided between the sliding seat and the locking block. The locking block has a locking part, and a locking groove corresponding to the locking part is provided on the inner wall of the battery cavity. The clamping bolt is used to move the battery along the length of the battery cavity and axially clamp the battery. During the movement, the sliding seat drives the locking block to flip, so that the locking part engages with the locking groove to lock the clamping bolt. The conductive component includes a positive electrode plate and a negative electrode ring. Two sets of the conductive component are provided, and the two sets of the conductive component are respectively disposed on the clamping bolt and the inner wall of the battery cavity. The positive electrode plates in the two sets of conductive components are electrically connected to each other and together form a positive output terminal. The negative electrode rings in the two sets of conductive components are electrically connected to each other and together form a negative output terminal, so that a corresponding positive and negative electrode conduction relationship is formed when the battery is installed in any orientation.
[0007] By adopting the above technical solution, a communication compartment and a battery cavity are set on the main body of the electricity meter, and a battery quick-installation mechanism is set in the battery cavity. The clamping bolt can drive the battery to move along the length of the battery cavity and form axial clamping on the battery, so that the battery always maintains a stable pre-tightened state after installation. This reduces the risk of battery loosening, displacement, and instantaneous power failure under long-term operation, transportation vibration, or external impact conditions, and improves the stability of backup power supply. Meanwhile, by setting a flip-up locking block in the mounting slot and utilizing the linkage drive structure between the sliding seat and the locking block, the locking block can be automatically flipped during the movement of the sliding seat, so that the locking part can automatically engage and lock with the locking slot. This allows for quick locking and releasing of the clamping bolt without the need for additional screw disassembly. Furthermore, by setting two sets of electrically connected conductive parts and using the positive electrode plate and negative electrode ring to form a corresponding positive and negative electrode conduction relationship, the battery can automatically form the correct conduction regardless of whether it is installed in the forward or reverse direction. Compared to existing technologies that use screw plates, high-locking-force clips, or deeply embedded spring clips, which result in complex assembly and disassembly and difficulty in applying force in narrow spaces, and which rely on manual identification of the positive and negative terminals of the battery, making reverse installation easy in confined environments, this application achieves integrated linkage of pressing and locking actions through a sliding linkage locking structure. Furthermore, it intentionally distinguishes between the positive and negative terminals of the battery during installation, reducing assembly and disassembly steps and lowering the required operating space. This allows operators to complete battery assembly and disassembly without having to extend their hands extensively into the distribution box. It also effectively reduces the risk of installation errors due to limited visibility or insufficient operating space during maintenance, and avoids problems such as communication module power failure, abnormal contact, or even circuit damage caused by reverse battery installation. This improves on-site replacement efficiency and power supply reliability, and significantly enhances maintenance convenience in confined installation environments.
[0008] Optionally, the linkage drive structure includes a first abutting surface and a second abutting surface disposed on the sliding seat, and a first wedge portion, a second wedge portion and a third abutting surface disposed on the locking block. The first wedge portion and the second wedge portion are respectively disposed on both sides of the length direction of the locking block. The first wedge portion is movably connected with the first abutting surface, the second wedge portion is movably connected with the second abutting surface, and the third abutting surface is disposed on the side of the second wedge portion facing the first wedge portion. When the sliding seat moves within the mounting groove, an offset flipping torque is formed between the first wedge-shaped portion and the first abutting surface, thereby driving the locking block to flip toward the locking groove, so that the locking portion engages with the locking groove.
[0009] By adopting the above technical solution, and by setting a first abutting surface, a second abutting surface, and corresponding first and second wedge-shaped parts, the sliding seat can generate an offset flipping torque through the mutual abutment between the wedge-shaped surfaces during its movement in the mounting groove. This drives the locking block to automatically flip towards the locking groove, achieving automatic engagement between the locking part and the locking groove. Compared to traditional structures that rely solely on elastic buckles or independent locking components, this application utilizes wedge-shaped guides to form a linkage flipping drive, which not only improves the stability and reliability of the locking action but also reduces the reliance on precise manual alignment during operation, avoiding the problem of incomplete locking due to installation deviations. At the same time, the progressive abutting fit between the wedge-shaped surfaces can also reduce the risk of local impact and jamming, making the locking process smoother, thereby improving the service life of the overall quick-installation mechanism and its long-term cyclic disassembly and assembly stability.
[0010] Optionally, a connecting plate is fixedly provided on one side of the sliding seat, and a first mounting surface is provided on the clamping bolt. The connecting plate is slidably fitted onto the first mounting surface. A guide groove is provided in the battery cavity, and the connecting plate is slidably connected to the guide groove. A connecting part is provided on one side of the connecting plate, and a sliding groove is provided on the energy meter body. The connecting part is slidably disposed in the sliding groove. The end of the connecting part away from the connecting plate extends out of the sliding groove, and an operating handle is fixedly provided at the end of the connecting part away from the connecting plate. Pulling the operating handle can drive the connecting plate to move in the sliding groove, thereby driving the clamping bolt to move in the battery cavity. The connecting plate can form a movable seal on the mounting port.
[0011] By adopting the above technical solution, and by setting up a connecting plate, guide groove, sliding groove, and exposed operating handle, operators can move the clamping bolt by pulling the operating handle without inserting their hands into the electricity meter, thereby realizing the installation and removal of the battery. This reduces the difficulty of applying force due to the narrow space in centralized installation environments and improves maintenance convenience. At the same time, the connecting plate can also form a movable seal on the installation port, thereby shielding and protecting the battery cavity after installation, reducing the risk of dust, moisture, and foreign objects entering the battery cavity, and improving the long-term stability and environmental adaptability of the battery module.
[0012] Optionally, a limiting component is provided in the sliding groove. The limiting component includes a limiting pin and a clamping spring. A receiving groove is formed on the inner wall of the sliding groove. The limiting pin is slidably disposed in the receiving groove. The clamping spring is disposed in the receiving groove. One end of the clamping spring is fixedly connected to the limiting pin, and the other end of the clamping spring is fixedly connected to the inner wall of the receiving groove. A snap-fit groove is formed on the connecting part. The end of the limiting pin away from the clamping spring is snap-fitted into the snap-fit groove.
[0013] By adopting the above technical solution, a limiting component consisting of a limiting pin and a clamping spring is set in the sliding groove, and the locking engagement between the limiting pin and the locking groove is utilized, so that the connecting part can automatically form a positioning lock after moving to the designated position, thereby preventing the clamping bolt from accidentally slipping under vibration, shaking or external force, and improving the stability of the battery after installation; at the same time, when disassembly is required, the limiting pin can disengage from the locking groove under the action of external force, thereby achieving quick release, thus taking into account both stable locking and convenient disassembly and assembly requirements.
[0014] Optionally, the battery quick-installation mechanism further includes a positioning component, which includes a crimping ring and a retraction spring. The crimping ring is disposed at one end of the clamping bolt, and the inner ring of the crimping ring is tapered. The inner diameter of the crimping ring on the side closer to the clamping bolt is smaller than the inner diameter of the crimping ring on the side farther from the clamping bolt. The crimping ring has a retraction groove communicating with the mounting port. The retraction spring is disposed on the inner wall of the battery cavity. When the clamping bolt moves within the battery cavity, the retraction spring can axially limit the battery, so that the battery gradually gets away from the radial constraint of the crimping ring and moves towards the mounting port under the elastic recovery action of the retraction spring, thereby achieving automatic retraction.
[0015] By adopting the above technical solution, and by setting a crimping ring with a tapered inner ring, the battery is gradually subjected to radial compression constraint during installation. This allows the battery to move along with the crimping bolt within the battery cavity, improving the stability of battery positioning and placement within the cavity and reducing radial swaying of the battery under vibration. Simultaneously, by setting a retraction spring and using it to axially limit the battery, the battery gradually detaches from the radial constraint of the crimping ring when the crimping bolt retracts. Under the elastic recovery of the retraction spring, it automatically moves towards the installation opening, thus achieving automatic retraction. Compared to traditional disassembly methods that require manual prying or complete pulling, this technical solution can actively push the battery out in confined spaces, reducing the difficulty of manual force application, improving maintenance efficiency, and reducing the risk of damage to the battery or conductive structure due to forced disassembly.
[0016] Optionally, a placement groove is formed on the inner wall of the battery cavity, and the ejector spring is disposed in the placement groove. One end of the ejector spring is fixedly connected to the inner wall of the placement groove, and the other end of the ejector spring is provided with a deformable part that abuts against the battery and an ejector part for restricting the movement of the battery. A first clearance groove is formed on the outer peripheral wall of the clamping bolt, and a second clearance groove is formed on the locking part. The first clearance groove and the second clearance groove are movably overlapped, and the ejector spring is slidably disposed in the first clearance groove and the second clearance groove.
[0017] By adopting the above technical solution, by setting a retraction spring in the placement slot and utilizing the combined action of the deformation part and the retraction part, the retraction spring can not only elastically adapt to the battery during installation, but also effectively push the battery out during disassembly, thereby improving the stability of the automatic retraction action. At the same time, by setting a first clearance groove and a second clearance groove on the clamping bolt and the locking part respectively, and making the two overlap, the retraction spring can obtain clearance space during the movement of the clamping bolt and the locking structure, thereby avoiding interference between the mechanisms and improving the overall structural movement coordination.
[0018] Optionally, the positive electrode sheet is configured as a thin sheet, and a contact groove is formed on the positive electrode sheet that corresponds to and mates with the positive electrode flange of the battery. The negative electrode ring is arranged around the outer periphery of the positive electrode sheet, and an insulating ring is provided between the positive electrode sheet and the negative electrode ring. The insulating ring is made of weather-resistant insulating material. The positive electrode sheet corresponds to the positive electrode of the battery, and the negative electrode ring corresponds to the negative electrode of the battery.
[0019] By adopting the above technical solution, the positive electrode sheet is made into a thin sheet and a contact groove is set on it to correspond to the positive electrode flange of the battery, so that the positive electrode sheet can form a more stable contact and conduction relationship with the positive electrode of the battery, thereby improving the stability of electrical connection and reducing contact resistance fluctuation. At the same time, by setting a negative electrode ring on the outer periphery of the positive electrode sheet and setting an insulating ring between the two, the positive and negative electrode conductive areas can form a clear isolation, thereby avoiding the risk of short circuit caused by miscontact between the positive and negative electrodes.
[0020] Optionally, the energy meter body is provided with a module installation area, and the communication compartment and the battery compartment are both located in the module installation area. The module installation area is provided with a cover, and the cover is provided with a flexible connecting post. The energy meter body has a connection hole that corresponds to and mates with the flexible connecting post. One end of the flexible connecting post is fixedly connected to the cover, and the other end of the flexible connecting post is movably inserted into the connection hole. The cover can be deflected relative to the flexible connecting post to facilitate battery maintenance operations under limited installation space conditions.
[0021] By adopting the above technical solution, a cover is set on the module installation area, and the cover can be deflected relative to the flexible connecting post by utilizing the movable plug-in cooperation between the flexible connecting post and the connecting hole. This allows for partial opening without completely removing the cover. Compared with the traditional overall disassembly type cavity cover structure, this application can effectively reduce the problem of the cover not being able to be fully opened in narrow spaces, improve the convenience of maintenance in centralized installation environments, and the cover deflection opening method can also reduce interference to surrounding wiring harnesses and electrical components during maintenance, reduce the risk of accidental contact, and improve on-site maintenance efficiency.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a communication compartment and a battery cavity on the main body of the energy meter, and installing a quick-installation mechanism for the battery within the battery cavity, the battery is kept in a stable pre-tightened state after installation. This reduces the risk of battery loosening, displacement, and momentary power outages during long-term operation, vibration, shock, or transportation, thus improving the stability of backup power supply. Simultaneously, by setting a flip-up locking block in the mounting slot and utilizing the linkage drive structure between the sliding seat and the locking block, the locking block automatically flips during the movement of the sliding seat, automatically engaging and locking the locking part with the locking slot. This eliminates the need for additional screws to disassemble and reassemble the clamping bolt, ensuring stable battery installation while improving maintenance convenience in confined spaces. Furthermore, by setting two sets of electrically connected conductive components and using a positive electrode plate and a negative electrode ring to form a corresponding positive and negative conduction relationship, the battery automatically achieves correct conduction regardless of whether it is installed in the correct orientation. This avoids the problem of reversed battery polarity due to space constraints or obstructed vision during maintenance, reducing manual operation difficulty and improving replacement efficiency and power supply reliability. 2. By setting a crimping ring with a tapered inner ring, the battery is gradually subjected to radial compression during installation. This allows the battery to move along with the crimping bolt within the battery cavity, improving the stability of battery positioning and placement within the cavity and reducing radial swaying under vibration. Simultaneously, by incorporating a retraction spring that axially limits the battery, the battery gradually detaches from the radial constraint of the crimping ring as the crimping bolt retracts. Under the elastic recovery of the retraction spring, the battery automatically moves towards the installation opening, achieving automatic retraction. Compared to traditional disassembly methods requiring manual prying or complete pulling, this solution actively pushes the battery out in confined spaces, reducing the difficulty of manual force application, improving maintenance efficiency, and minimizing the risk of damage to the battery or conductive structure due to forced disassembly.

Detailed Implementation
[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail below.
[0031] This application discloses a smart energy meter with an integrated battery module structure for vibration resistance and steady-state operation.
[0032] Reference Figure 1 and Figure 2 A smart energy meter with an integrated battery module structure for vibration resistance and stability includes an energy meter body 1 and a battery quick-installation mechanism 2. The energy meter body 1 is provided with a communication compartment 11 and a battery cavity 12. The battery cavity 12 is located on one side of the communication compartment 11. The battery quick-installation mechanism 2 is installed in the battery cavity 12. The battery quick-installation mechanism 2 can ensure the vibration resistance and stable installation of the battery while taking into account the need for convenient disassembly and assembly under limited installation space conditions.
[0033] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, the electricity meter body 1 is provided with a module installation area 15. The module installation area 15 is provided with a communication compartment 11 and a battery compartment 12. The communication compartment 11 is used to install a communication module, while the battery compartment 12 is used to install a battery. The module installation area 15 is provided with a cover 16, which is embedded in the module installation area 15. A flexible connecting post 161 is fixed at one corner of the cover 16. The electricity meter body 1 is provided with a connection hole 151. One end of the flexible connecting post 161 is fixedly connected to the cover 16, and the other end of the flexible connecting post 161 is movably inserted into the connection hole 151. The end of the flexible connecting post 161 inserted into the connection hole 151 is provided with an anti-detachment part.
[0034] In this embodiment, the flexible connecting post 161 is made of rubber. Under normal conditions, the cover 16 is fastened and fixed to the module mounting area 15, and a sealing strip is provided around the cover 16 to improve the overall sealing performance. When there is sufficient installation space, the cover 16 can be opened directly and flipped outward; when the installation space is limited, the cover 16 can be deflected relative to the flexible connecting post 161, thereby turning it to one side for subsequent maintenance operations.
[0035] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the battery quick-installation mechanism 2 includes a clamping bolt 21, a sliding seat 22, a locking block 23, a limiting member 26, a conductive member 24, and a positioning member 27. The clamping bolt 21 is cylindrical and is slidably disposed in the battery cavity 12. The battery cavity 12 has an installation port 121 for replacing the battery. An installation groove 211 is provided through the clamping bolt 21. The sliding seat 22 is slidably disposed in the installation groove 211. A connecting plate 25 is fixedly disposed on one side of the sliding seat 22. A first mounting surface 212 is provided on the clamping bolt 21. The connecting plate 25 is slidably attached to the first mounting surface 212.
[0036] A guide groove 123 is provided inside the battery cavity 12. The connecting plate 25 is slidably connected to the guide groove 123, and the connecting plate 25 can movably seal the mounting port 121. A connecting part 251 is provided on one side of the connecting plate 25. A sliding groove 13 is provided on the energy meter body 1. The connecting part 251 is slidably disposed in the sliding groove 13. One end of the connecting part 251 is fixedly connected to the connecting plate 25, and the other end of the connecting part 251 is fixedly provided with an operating handle 252. The operating handle 252 is set in the shape of a hexagonal prism, and an internal hexagonal insertion groove is provided on the operating handle 252.
[0037] A rotating shaft is fixed on the locking block 23. The locking block 23 is rotatably mounted in the mounting groove 211 via the rotating shaft. The locking block 23 is mounted above the sliding seat 22, and a clearance is provided between the locking block 23 and the mounting groove 211 to allow the locking block 23 to rotate. A linkage drive structure for driving the locking block 23 to rotate is provided between the sliding seat 22 and the locking block 23. The linkage drive structure includes a first abutment surface 221 and a second abutment surface 222 provided on the sliding seat 22, and a first wedge-shaped portion 232, a second wedge-shaped portion 233, and a third abutment surface 234 provided on the locking block 23. The sliding... The seat 22 is provided with a first abutting surface 221 and a second abutting surface 222 on the side facing the locking block 23. The locking block 23 is also provided with a first wedge-shaped part 232, a second wedge-shaped part 233 and a third abutting surface 234 on the side facing the sliding seat 22. The first wedge-shaped part 232 and the second wedge-shaped part 233 are respectively provided on both sides of the length direction of the locking block 23. The first wedge-shaped part 232 is movably attached to the first abutting surface 221, the second wedge-shaped part 233 is movably attached to the second abutting surface 222, and the third abutting surface 234 is provided on the side of the second wedge-shaped part 233 facing the first wedge-shaped part 232.
[0038] A locking part 231 is provided on the side of the locking block 23 away from the sliding seat 22, and a locking groove 122 is provided on the inner wall of the battery cavity 12. The locking part 231 and the locking groove 122 are engaged and cooperated.
[0039] Specifically, the clamping bolt 21 applies continuous axial pressure to the battery along the length of the battery cavity 12, ensuring that both ends of the battery remain in contact with their respective conductive parts 24, thereby reducing changes in the contact gap caused by axial movement of the battery under vibration. Simultaneously, after the clamping bolt 21 moves the battery to the predetermined position, the sliding seat 22 continues to slide relative to the locking block 23. Through the coordinated action of the first wedge portion 232, the second wedge portion 233, and the third abutment surface 234, the locking block 23 is driven to rotate around the axis of rotation, causing the locking part 231 to mechanically engage with the locking groove 122, thus creating a reverse limit on the clamping bolt 21 and preventing it from retracting under long-term vibration.
[0040] Reference Figure 3 and Figure 4In this embodiment, the limiting member 26 is installed in the sliding groove 13. The limiting member 26 includes a limiting pin 261 and a clamping spring 262. A receiving groove 14 is provided on the inner wall of the sliding groove 13. The limiting pin 261 is cylindrical. One end of the limiting pin 261 is slidably disposed in the receiving groove 14, and the other end of the limiting pin 261 is hemispherical. The clamping spring 262 is disposed in the receiving groove 14. One end of the clamping spring 262 is fixedly connected to the inner wall of the receiving groove 14, and the other end of the clamping spring 262 is fixedly connected to one end of the limiting pin 261. A hemispherical snap-fit groove 2511 is provided on the connecting part 251. The hemispherical end of the limiting pin 261 is snap-fitted into the snap-fit groove 2511.
[0041] In this embodiment, two sets of limiting members 26 are provided, and the two sets of limiting members 26 are symmetrically arranged along the width direction of the sliding groove 13.
[0042] In addition, in other embodiments of this application, the limiting member 26 can be directly set as a limiting protrusion, which can be movably engaged with the locking groove 2511.
[0043] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment, the conductive element 24 includes a positive electrode 241, a negative electrode ring 242, and an insulating ring 243. Both the positive electrode 241 and the negative electrode ring 242 are electrically connected to the PCB board installed in the electricity meter. The negative electrode ring 242 is arranged around the positive electrode 241. The insulating ring 243 is made of weather-resistant insulating material and is arranged between the positive electrode 241 and the negative electrode ring 242. The positive electrode 241 is set in the shape of a thin sheet. A contact groove 2411 adapted to the positive electrode flange of the battery is also formed on the positive electrode 241. The negative electrode ring 242 protrudes from the plane of the positive electrode 241.
[0044] The battery involved in this embodiment is a lithium thionyl chloride battery with a standard voltage of 3.6V. The positive electrode 241 corresponds to the positive electrode of the battery, and the negative electrode ring 242 corresponds to the negative electrode of the battery. One end of the battery cavity 12 is set as the first mounting end, and the other end of the battery cavity 12 is set as the second mounting end. Two sets of conductive components 24 are provided. One set of conductive components 24 is installed on the end face of the clamping bolt 21 facing the second mounting end, and the other set of conductive components 24 is set on the inner wall of the battery cavity 12 at the second mounting end.
[0045] It is worth noting that in this embodiment, the positive electrode plates 241 in the two sets of conductive components 24 are electrically connected to each other and together constitute the positive output terminal of the battery; the negative electrode rings 242 in the two sets of conductive components 24 are electrically connected to each other and together constitute the negative output terminal of the battery. Since the two ends of the battery respectively form a corresponding conductive relationship of "central positive electrode contact area + peripheral negative electrode contact area", the positive and negative electrode correspondence output to the PCB board will not change regardless of the orientation of the battery installation.
[0046] Reference Figure 4 , Figure 5 and Figure 6 In this embodiment of the application, the positioning member 27 includes a crimping ring 271 and a retracting spring 272. The crimping ring 271 is configured as a circular ring structure, and the inner ring of the crimping ring 271 is tapered, that is, the inner diameter of the crimping ring 271 near the clamping bolt 21 is smaller than the inner diameter of the crimping ring 271 away from the clamping bolt 21. The crimping ring 271 can be made of a wear-resistant polymer material with elastic cushioning properties, such as TPU, nylon-coated parts or hard rubber composite parts. The crimping ring 271 has a withdrawal groove 2711, which communicates with the mounting port 121. The crimping ring 271 is coaxially fixed to the end of the clamping bolt 21 near the mounting port 121. The inner wall of the battery cavity 12 has a placement groove 124. The withdrawal spring 272 is elongated, with a fixing part 2721 at one end and a deformation part 2722 and a withdrawal part 2723 at the other end. The withdrawal spring 272 is fixed in the placement groove 124 through the fixing part 2721. The outer peripheral wall of the clamping bolt 21 has a first... A first clearance groove 213 is provided, a second clearance groove 2311 is provided on the locking part 231, and a third clearance groove is provided on the pressing ring 271. The third clearance groove is connected to the first clearance groove 213. The ejector spring 272 is slidably disposed in the first clearance groove 213 and the second clearance groove 2311. The battery can slide against the deformable part 2722. The ejector part 2723 is set in the shape of a right-angled wedge. One end of the battery can move against the ejector part 2723. That is, the side of the ejector part 2723 that abuts against one end of the battery is set as a vertical plane, thereby realizing that the ejector part 2723 restricts the movement of the battery.
[0047] Furthermore, in the initial state, the clamping bolt 21 is located at the first mounting end. At this time, the end face of the clamping bolt 21 facing the second mounting end is basically flush with the side of the mounting port 121 near the first mounting end, and the ejection groove 2711 is connected to the mounting port 121.
[0048] Then place the new battery at the mounting port 121. At this time, there is no need to distinguish the positive and negative directions of the battery. Then push the operating handle 252 to move the clamping bolt 21 towards the second mounting end, so that the clamping bolt 21 clamps and fixes the battery in the battery cavity 12.
[0049] Specifically, the conductive element 24 adopts a coaxial surrounding conductive structure, in which the positive electrode 241 is located at the center, and the negative electrode ring 242 is arranged around the outer periphery of the positive electrode 241, and is insulated from the positive electrode 241 by an insulating ring 243. Since the positive terminal of the lithium thionyl chloride battery is usually provided with a raised electrode structure, while the negative terminal is a corresponding outer ring electrode area, no matter which direction the battery is installed in the battery cavity 12, the central raised part of one end of the battery can form an electrical connection with the positive electrode 241 in the corresponding set of conductive elements 24, while the outer periphery of the battery forms an electrical connection with the negative electrode ring 242; at the same time, the other end of the battery can also form a corresponding conduction with another set of conductive elements 24.
[0050] When the battery is installed in the correct orientation, the positive electrode protrusion contacts the positive electrode plate 241 located at the second mounting end, while the outer periphery of the negative electrode contacts the corresponding negative electrode ring 242. When the battery is installed in the reverse orientation, the positive electrode protrusion contacts another set of positive electrode plates 241 located at the end of the clamping bolt 21, and the outer periphery of the negative electrode contacts another set of negative electrode rings 242. Since the two sets of conductive elements 24 are respectively located at opposite ends of the battery cavity 12, and the two sets of conductive elements 24 adopt the same coaxial surrounding conductive structure, the corresponding positive and negative electrode conduction relationship can be automatically formed when the battery is installed in either orientation, thus achieving an installation effect that does not require distinguishing between the positive and negative electrode orientations. By setting the positive electrode plate 241 as a center contact structure and forming a radial surrounding contact with the negative electrode ring 242, the reverse connection problem caused by the battery being installed backwards can be effectively avoided. At the same time, the stability of the battery end contact can be improved, and reliable conduction can still be maintained in a vibration environment.
[0051] Furthermore, in the initial state, the sliding seat 22 is located on the side of the mounting groove 211 near the first mounting end, the second wedge-shaped portion 233 overlaps the second abutment surface 222, and the locking portion 231 is completely located within the mounting groove 211. Due to the limiting effect of the inner wall of the battery cavity 12, the locking portion 231 cannot be flipped outward. As the clamping bolt 21 moves towards the second mounting end, after the clamping bolt 21 clamps the battery to the predetermined position, the locking portion 231 corresponds to the locking groove 122. At this time, if the operating handle 252 is continued to be pushed, the sliding seat 22 will continue to slide within the mounting groove 211, and the second wedge-shaped portion 233 will gradually disengage from the second abutment surface 222.
[0052] Simultaneously, the first wedge-shaped portion 232 gradually overlaps with the first abutting surface 221, and after the second wedge-shaped portion 233 completely disengages from the second abutting surface 222, the third abutting surface 234 forms an overlapping engagement with the second abutting surface 222, thereby causing the sliding seat 22 to rotate and the locking block 23 to flip, causing the locking portion 231 provided on the locking block 23 to flip outward and engage with the locking groove 122. At the same time, the limiting pin 261 engages with the snap-fit groove 2511, and the portion of the connecting plate 25 located on the side of the mounting opening 121 blocks the mounting opening 121.
[0053] During later maintenance, when the battery needs to be replaced, simply pull the operating handle 252 to move the clamping bolt 21. The clamping bolt 21 moves the battery synchronously via the crimping ring 271. During the movement, the clamping bolt 21 compresses the ejection spring 272, causing the ejection spring 272 to elastically deform into the placement groove 124. The end of the battery closest to the clamping bolt 21 is compressed and deformed 2722, and comes into contact with the ejection part 2723. Since the crimping ring 271 has a through ejection groove 2711, when the clamping bolt 21 moves the battery to near its limit position, the ejection part 2723 axially limits the battery, while the crimping ring 271 continues to move the clamping bolt 21. Because the inner ring of the crimping ring 271 is tapered, the end of the battery gradually breaks away from the radial enclosure constraint of the crimping ring 271. At the same time, due to the elastic recovery of the ejection spring 272 and the battery's own restricted release, the battery moves towards the mounting port 121, thereby achieving automatic ejection.
[0054] In other embodiments of this application, an elastic buffer pad may be provided at one end of the ejector spring 272 where the ejector part 2723 is provided. The elastic buffer pad can provide stable reset and auxiliary support for the ejector spring 272, which is not shown in the accompanying drawings of the embodiments of this application.
[0055] The implementation principle of the smart energy meter with vibration-resistant and stable integrated battery module structure in this application embodiment is as follows: by sliding the clamping bolt 21 in the battery cavity 12, and driving the clamping bolt 21 to move along the length direction of the battery cavity 12 by the operating handle 252, the clamping bolt 21 can form an axial clamping effect on the battery, thereby ensuring that the battery always maintains a stable fit under vibration environment and avoiding power outage or poor contact due to loosening; Meanwhile, during the sliding process of the sliding seat 22 in the mounting groove 211, the locking block 23 is driven to flip by the cooperation of the first wedge 232, the second wedge 233 and the third abutting surface 234 with the first abutting surface 221 and the second abutting surface 222. This causes the locking part 231 to automatically engage with the locking groove 122 and lock, thereby forming a mechanical locking structure after the battery is pressed, improving the overall vibration resistance and stability performance, and preventing the clamping bolt 21 from retracting due to long-term vibration.
[0056] Furthermore, the conductive component 24 enables a non-polarity installation effect that eliminates the need to distinguish the battery installation direction. This not only avoids the risk of reverse connection caused by the battery being installed backwards, but also reduces the manual identification and adjustment steps under limited operating space conditions, thereby improving on-site maintenance efficiency. Furthermore, after the battery is installed, the connecting plate 25 can simultaneously seal the mounting port 121, and achieve position limiting through the snap-fit between the limiting pin 261 and the snap-fit groove 2511, thereby improving structural stability and anti-loosening effect. During later maintenance, simply pulling the operating handle 252 can release the locking state and drive the clamping bolt 21 to move in the opposite direction. The clamping ring 271 moves the battery back towards the mounting port 121 simultaneously with the clamping bolt 21. At the same time, the ejection spring 272 undergoes elastic deformation during the pressure process, and limits the battery through the ejection part 2723.
[0057] When the battery moves close to the mounting port 121, the ejection part 2723 restricts the battery from continuing to move synchronously with the clamping bolt 21. At this time, the battery automatically pops out towards the mounting port 121 under the action of inertia and the blocking action of the ejection part 2723, and gets out of the constraint of the crimping ring 271 through the ejection groove 2711, thereby realizing the automatic ejection function of the battery.
[0058] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
