Description

Technical Field

[0001] This utility model relates to the field of power metering equipment technology, and in particular to a user visualization management unit for smart energy meters. Background Technology

[0002] Traditional smart meter user visualization management units typically employ a fully enclosed structural design. Once the equipment is put into use, its internally fixed programs and data cannot be updated or upgraded on-site. This closed design means that even if new metering algorithm optimizations, communication protocol upgrades, or functional expansion requirements arise, existing equipment cannot achieve functional iteration through simple technical means. Especially during the intelligent transformation of power systems, this structural defect severely restricts the maintainability and technological scalability of the equipment. Existing products generally use a one-time packaging process, requiring disassembly for upgrades. Furthermore, program errors or data anomalies occurring during equipment operation cannot be repaired through external interfaces, significantly reducing product reliability and lifespan.

[0032] Please refer to the reference. Figures 1 to 3 This application proposes a smart energy meter user visualization management unit including a housing and a chip (not shown). The housing is formed by connecting an upper cover 1 and a bottom cover 5 to form a mounting cavity. The bottom cover 5 has a programming hole 51 that communicates with the mounting cavity. The chip is fixed in the mounting cavity and is set in accordance with the programming hole 51.

[0033] The outer shell refers to the protective structure that encloses the internal electronic components. It can be made of injection-molded engineering plastic and connected to the bottom shell 5 via clips or screws to form a sealed space, providing dust and water protection. The mounting cavity is the space inside the outer shell used to house the chip. Its size is designed according to the chip's volume, and a fixing bracket can be installed inside the cavity to ensure the chip's stable position. The programming hole 51 is a through-hole that penetrates the wall thickness of the bottom shell 5. The hole diameter is adapted to the standard programming interface size, for example, a 2 mm diameter circular hole. Its axis is aligned with the chip programming port, forming a physical connection channel between the external programming device and the chip. The chip refers to an integrated circuit module with data storage and processing functions. Specifically, a microcontroller that supports in-circuit programming can be selected, and its programming contacts extend to the area directly below the programming hole 51 via wires.

[0034] Specifically, during device assembly, the chip is first fixed in a preset position on the bottom shell 5, ensuring a spatial correspondence between its programming interface and the programming hole 51 on the bottom shell 5. After the shell is closed, the mounting cavity forms a sealed protective space, allowing external programming devices to directly contact the chip interface through the programming hole 51 to write programs. The positioning and coordination between the programming hole 51 and the chip eliminates the need to disassemble the shell in traditional solutions, maintaining the overall airtightness of the device while ensuring the maintainability of the chip's functionality. When an upgrade is required, the operator only needs to insert the programming probe into the programming hole 51 on the bottom shell 5 to complete data transmission, avoiding the risk of seal failure caused by repeated disassembly and reassembly of the shell.

[0035] Through the above technical solution, this application realizes the program upgrade function of the smart energy meter user visualization management unit device in a closed state, solving the problem of premature scrapping of outdoor equipment due to the inability to update firmware. The precise positioning of the programming hole 51 and the chip ensures the reliability of data transmission, maintains the integrity of the shell structure, significantly reduces the frequency of equipment maintenance and operating costs, and extends the service life of the equipment.

[0036] like Figure 3 As shown, this application further proposes that the bottom shell 5 has multiple programming holes 51, and the multiple programming holes 51 are spaced apart.

[0037] The multiple programming holes 51 refer to two or more independent hole structures formed on the surface of the bottom shell 5. These can be achieved using stamping or injection molding processes. Their function is to provide multiple physically isolated programming interfaces, preventing the device from being unable to be upgraded due to the failure of a single channel. The spacing setting refers to maintaining a preset distance between adjacent programming holes 51. This can be achieved by controlling the hole distribution through mold design. Its function is to prevent interference during programming tool operation and to disperse stress concentration in the stress-bearing areas of the shell.

[0038] Specifically, multiple programming holes 51 are spaced apart on the bottom shell 5, forming multiple independent channels. When a programming hole 51 malfunctions due to blockage by foreign objects or structural damage, other holes can be selected for programming. The spacing between the holes ensures that the programming tool will not interfere with each other when inserted, and that the shell is subjected to uniform force during the programming operation, avoiding local deformation.

[0039] Through the above technical solution, this application solves the problem that the single programming hole 51 structure can easily lead to the interruption of the upgrade operation, ensuring that the device can still complete the program update through the backup interface when some interfaces fail, and at the same time improves the stability of the programming operation and the reliability of the shell structure by the hole spacing distribution.

[0040] This application further proposes that the shape of the programming hole 51 is elliptical, circular, or polygonal.

[0041] Among them, an ellipse refers to a closed curve structure with different lengths for its major and minor axes. It can be formed on the base shell 5 using stamping or injection molding processes, and its major axis direction provides a larger tool insertion space. A circle refers to a centrally symmetrical closed curve structure, whose uniform stress distribution avoids localized stress concentration. A polygon refers to a closed shape formed by three or more straight line segments connected end-to-end. It can be manufactured using wire cutting or laser cutting processes, and its edge structure can form a tool positioning reference.

[0042] Specifically, the elliptical hole's major axis allows the programming tool to be inserted at an angle, accommodating the operational needs of tools of different sizes; the circular hole simplifies the processing steps through its symmetrical structure, while eliminating the risk of stress concentration at the corners; the polygonal hole utilizes the geometric constraints of the edges and the tool's contact surface to achieve precise alignment during the programming process. These three shapes of programming holes 51 complement each other: the elliptical is suitable for scenarios requiring expanded operating space, the circular is suitable for cost-sensitive scenarios, and the polygonal is suitable for scenarios with high positioning accuracy requirements, together forming a structural solution that covers a variety of programming tools.

[0043] Through the above technical solutions, this application solves the problem of poor contact caused by the mismatch between the shape of the programming tool and the programming hole 51, and improves the success rate of programming operation; by optimizing the hole structure, it reduces material loss during the processing and extends the service life of the bottom shell 5; by utilizing the geometric matching characteristics of the polygonal edges and the tool shape, it reduces the time for manual alignment operation.

[0044] Please refer to the reference. Figures 2 to 4 This application further proposes that a battery slot 14 is provided on the outer side of the bottom shell 5, and a writing hole 51 is provided on the bottom wall of the battery slot 14.

[0045] The battery slot 14 refers to a recessed structure located on the outer side of the bottom shell 5. It can be formed by stamping or injection molding and is used to accommodate the battery assembly and form an independent installation space. The programming hole 51 is located on the bottom wall of the battery slot 14, meaning that the hole is located on the bottom plane of the battery slot 14. It can be achieved by opening a hole in a mold or by machining, so that the programming hole 51 is directly exposed when the battery assembly is removed.

[0046] Specifically, the battery compartment 14 provides an independent mounting area for the battery assembly, and the programming hole 51 is located on the bottom wall of the battery compartment 14, creating a spatial nesting relationship between the two. When a programming operation is required, the programming hole 51 can be directly accessed by removing the battery assembly, without the need for a separate external opening. The layout of the programming hole 51 on the bottom wall of the battery compartment 14 utilizes the vertical direction of the battery mounting space, avoiding the need for additional openings in other areas of the bottom shell 5.

[0047] Through the above technical solution, this application solves the conflict between the battery installation space and the layout of the writing hole 51, and realizes that the writing operation can be completed without damaging the shell structure when upgrading the device, while maintaining the structural strength and sealing performance of the bottom shell 5.

[0048] like Figure 2 As shown, this application further proposes a smart energy meter user visualization management unit including a battery cover 7, which covers the opening of the battery slot 14.

[0049] The battery cover 7 refers to the protective component that covers the opening of the battery compartment 14. It can be implemented using a snap-on or threaded connection structure, and a sealing ring can be set on its edge to enhance the sealing performance. The slot of the battery compartment 14 refers to the installation opening of the battery compartment. It can be designed as a rectangular or circular structure, and a guide boss can be set on the edge of the slot to match the installation trajectory of the battery cover 7.

[0050] Specifically, the battery cover 7 and the battery slot 14 are mechanically connected to form a closed structure. When the battery cover 7 is closed, its covered area completely blocks the internal space of the battery slot 14, preventing external foreign objects from entering the battery compartment through the slot. During equipment operation, the sealing structure of the battery cover 7 effectively isolates moisture, dust, and other contaminants, preventing oxidation of battery contacts or moisture damage to the circuit board. When battery replacement or maintenance is required, the battery cover 7 can be manually unlocked to fully expose the slot for disassembly and assembly of internal components; this process can be completed without disassembling the equipment casing.

[0051] Through the above technical solution, this application prevents external contaminants from entering the device through the battery compartment 14 and contaminating the programming hole 51, ensuring the cleanliness of the chip programming interface; reducing the risk of short circuits caused by foreign object intrusion and maintaining the stability of device operation; while retaining the convenience of battery replacement operation and avoiding the increase in maintenance complexity caused by the addition of protective structures.

[0052] This application further proposes a smart energy meter user visualization management unit including a meter mounting plate 10, which is located on the side of the bottom shell 5 away from the top cover 1, and is used to fix the meter mounting plate 10 to an external object.

[0053] The mounting plate 10 refers to the installation structure used to support the weight of the device. It can be made of stamped metal or injection-molded metal, with its planar extension forming a contact surface with external objects. This structure, installed independently of the outer casing, avoids compromising the casing's seal. The side of the bottom shell 5 facing away from the top cover 1 refers to the outer surface of the equipment formed after the casing is assembled. This can be achieved by injection molding to create a flat mounting surface. This location ensures that the mounting plate 10 does not affect the spatial layout of the internal components of the casing after installation.

[0054] Specifically, the mounting plate 10 is directly connected to the outer surface of the base shell 5 to form a suspension fulcrum. When the device needs to be installed, the operator only needs to hook the extension of the mounting plate 10 onto the preset fixed bracket or wall to complete the fixation. This installation method does not require penetrating the shell or using fasteners. Physical fixation is achieved through external contact while keeping the shell completely sealed. During the installation process, the correspondence between the chip inside the shell and the programming hole 51 is not affected by external forces, and program upgrades can be performed directly through the programming hole 51 during maintenance.

[0055] Through the above technical solution, this application achieves rapid installation and positioning of the device without disassembly, without compromising the sealing of the outer casing during installation. During maintenance, program upgrades can be performed directly through the pre-reserved programming hole 51. This structure, while ensuring the stability of the device, avoids physical damage to the device casing caused by traditional installation methods, providing operable hardware conditions for remote maintenance.

[0056] This application further proposes that the bottom shell 5 is provided with a hanging plate groove 15 on the side opposite to the top cover 1, and at least part of the mounting plate 10 is accommodated and confined within the hanging plate groove 15.

[0057] The mounting plate groove 15 refers to a recessed structure on the outer surface of the bottom shell 5, which can be formed by stamping or injection molding. Its depth is matched with the thickness of the mounting plate 10. This groove structure provides a spatial positioning reference for the mounting plate 10 and achieves assembly guidance through geometric constraints.

[0058] The limiting function refers to the mechanical interference formed by the contact surface between the inner wall of the mounting groove 15 and the edge of the meter plate 10. This can be achieved by setting a protrusion on the groove wall or setting a snap-fit ​​structure on the meter plate 10. This feature forms a barrier in the vertical hanging direction, preventing the meter plate 10 from falling out of the installation position when subjected to external force.

[0059] Specifically, during installation, the mounting plate 10 slides into the groove 15 along its extension direction. The sidewalls of the groove provide lateral constraint on the mounting plate 10, while the bottom plane provides longitudinal support. Once the mounting plate 10 is fully embedded, the limiting boss inside the groove makes surface contact with the edge of the mounting plate 10, generating a reaction force to balance the gravitational load when the device is in the hanging state. This structural design allows the mounting plate 10 to achieve precise alignment without auxiliary positioning tools during assembly, while mechanical limiting eliminates the risk of loosening associated with traditional threaded fastening methods.

[0060] Through the above technical solution, this application achieves rapid positioning and installation of the meter mounting plate 10 and the device body, eliminating assembly defects caused by manual alignment errors. Under vibration conditions of the meter box, the geometric fit between the mounting plate groove 15 and the meter mounting plate 10 can effectively suppress relative displacement and avoid fatigue failure of the connection structure due to long-term use. Maintenance personnel can replace the meter mounting plate 10 separately without disassembling the entire device, significantly reducing the intensity of on-site maintenance work.

[0061] Please refer to the reference. Figure 3 and Figure 5 This application further proposes that the upper cover 1 is provided with one of the two, a positioning post 53 and a positioning hole 13, and the bottom shell 5 is provided with the other of the two, with the positioning post 53 at least partially inserted into the positioning hole 13.

[0062] The positioning post 53 refers to a protruding structure used for mechanical alignment, which can be implemented as a cylinder or prism, and its height can be set to cover 50%-80% of the outer shell thickness. The positioning hole 13 refers to a groove structure that matches the shape of the positioning post 53, which can be machined as a through hole or a blind hole, with the hole diameter tolerance controlled within ±0.1mm of the diameter of the positioning post 53. The two form a forced constraint through a geometric complementary relationship, eliminating translational deviations in the six degrees of freedom during assembly.

[0063] Specifically, when the top cover 1 and the bottom shell 5 are closed, the end of the positioning post 53 first contacts the edge of the positioning hole 13 and slides into the predetermined position along the hole wall under pressure. The side wall of the post forms a surface contact with the hole wall, preventing lateral displacement; the top of the post forms a point contact with the bottom of the hole, limiting longitudinal displacement. This mechanical interlocking structure ensures that the sealing ring of the mounting cavity is evenly compressed, avoiding local stress concentration caused by misalignment. In repeated disassembly and assembly scenarios, the positioning reference remains constant, ensuring that the spatial correspondence between the chip and the programming hole 51 remains unchanged each time it is reassembled.

[0064] like Figure 1 and Figure 2 As shown, this application further proposes a technical solution for a smart energy meter user visualization management unit, including the following optional solutions: the upper cover 1 is provided with a transparent window 2; at least one of the upper cover 1 and the bottom shell 5 is provided with a wire connection hole 16 communicating with the mounting cavity; the upper cover 1 is equipped with an indicator light; the device also includes a button assembly 4 disposed in the mounting cavity.

[0065] The transparent window 2 refers to the light-transmitting area covering the surface of the upper cover 1, which can be made of acrylic or tempered glass, and is used to directly display the data screen content inside the mounting cavity. The wire connection hole 16 refers to the channel structure penetrating the upper cover 1, which can be implemented using a rubber sealing ring and a metal interface, and is used to allow external data cables to connect to the chip inside the mounting cavity. The indicator light refers to the light-emitting element embedded in the upper cover 1, which can be implemented using surface-mount LEDs and light guide pillars 3, and is used to provide feedback on the device's operating status through color or flashing patterns. The button assembly 4 refers to the touch module installed inside the cavity, which can be implemented using silicone buttons and PCB board contacts, and is used to transmit a trigger signal to the chip upon pressing.

[0066] Specifically, the transparent window 2 achieves data visualization through physical isolation, preventing damage to the casing's seal due to opening the cover; the wire connection hole 16 establishes a physical connection between external devices and the chip through a preset channel, supporting direct transmission of firmware upgrade data to the internal circuitry; the indicator light transmits light signals through the material of the top cover 1, reflecting the device's operating status in real time; the button assembly 4 uses an internal encapsulation structure to input operating commands, preventing dust or moisture intrusion caused by external openings. Each technical feature can be implemented independently or combined, addressing data observation, external interaction, status monitoring, and functional control while maintaining the device's airtightness.

[0067] Through the above technical solution, this application enables data display, device connection, status feedback and operation control without damaging the outer shell, solving the technical defects of closed devices that cannot be externally maintained and upgraded, while reducing the risk of seal failure caused by opening the cover and extending the service life of the device.

[0068] like Figure 5 As shown, this application further proposes that the upper cover 1 is provided with a reinforcing rib 11, which is located inside the mounting cavity.

[0069] The reinforcing rib 11 refers to a strip-shaped protrusion or recess extending along the inner surface of the upper cover 1. It can be integrally molded using the same material as the upper cover 1 body through injection molding, serving to increase the local rigidity of the upper cover 1 and disperse stress generated by external loads. The mounting cavity refers to the closed space formed by the upper cover 1 and the bottom shell 5. The reinforcing rib 11 is located inside this space, neither affecting the external sealing of the outer shell nor hindering the chip area through internal support structures.

[0070] Specifically, the reinforcing ribs 11 are distributed in a grid or radial pattern on the inner wall of the upper cover 1. When external pressure is applied to the outer shell, the reinforcing ribs 11 transfer the load to the surrounding shell through the rigidity of their geometric shape, preventing local dents or deformation. During the programming operation in the programming hole 51, the reinforcing ribs 11 provide stable support for the chip mounting area, preventing the chip from shifting contact with the programming interface due to external pressure.

[0071] Through the above technical solution, this application solves the problem of programming failure caused by insufficient shell structure strength, ensuring that the chip is always in a stable and controlled state during the programming process, and providing a reliable structural foundation for remote upgrade function.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
