Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, and in particular to a shock-absorbing component for electricity meters. Background Technology

[0002] As the core device for measuring electricity consumption, the stability of electricity meters directly affects the accuracy and reliability of electricity metering. In practical applications, electricity meters are installed in a wide variety of scenarios, including not only relatively stable indoor power distribution rooms, but also complex vibration environments such as industrial workshops, distribution boxes along rail transit lines, and outdoor temporary power supply facilities. The sources of vibration in these scenarios are diverse, including mechanical vibrations from industrial equipment operation, transmitted vibrations from vehicles, and sudden environmental impacts (such as external forces colliding with distribution boxes), with significant differences in vibration frequency and amplitude.

[0003] Traditional electricity meter installations often employ rigid fixing or single-material shock-absorbing structures, which have significant technical drawbacks: rigid fixing offers virtually no shock absorption, with vibrations directly transmitted to the meter's interior, easily leading to loosening of internal electronic components, solder joint detachment, metering errors, or even equipment malfunctions; simple shock-absorbing structures such as single rubber pads can only provide limited buffering for vibrations of specific frequencies, offering poor isolation against high-frequency vibrations and easily causing resonance in low-frequency vibrations. Furthermore, they are prone to aging and elasticity decay after long-term use, resulting in a continuous decline in shock absorption performance; some shock-absorbing structures do not fit well enough against the meter's outer casing, making them prone to relative sliding during vibration, which not only affects the shock absorption effect but may also cause wear and tear on the meter's outer casing due to friction.

[0004] With the increasing demands for stability in power system metering equipment and the growing number of complex installation environments, traditional vibration damping methods can no longer meet practical needs. Therefore, developing a vibration damping component that can adapt to multi-frequency vibrations, provide long-lasting and stable damping effects, and is well-compatible with electricity meters has become a key technological requirement for solving the vibration interference problem of electricity meters.

[0024] This application provides a shock-absorbing component for an electricity meter, including a mounting base 1 and a composite shock-absorbing body disposed between the mounting base 1 and the electricity meter. The composite shock-absorbing body is provided with an elastic protrusion buffer layer 2, a honeycomb shock-absorbing core 3, and a flexible wrapping shock-absorbing layer 4 in sequence along the direction away from the mounting base 1. The elastic protrusion buffer layer 2 has a plurality of matrix-distributed elastic protrusions 21 on the side facing the mounting base 1. The elastic protrusions 21 abut against the mounting base 1 and can elastically deform along the axial direction. The honeycomb shock-absorbing core 3 has a plurality of through shock-absorbing cavities inside, and the inner wall of the shock-absorbing cavity has a plurality of annular damping protrusions 31. The flexible wrapping shock-absorbing layer 4 has an arc-shaped fitting groove adapted to the outer shell of the electricity meter on the side away from the honeycomb shock-absorbing core 3. The inner wall of the arc-shaped fitting groove is flexibly fitted to the outer shell of the electricity meter. The composite shock-absorbing body is provided with a plurality of radially extending elastic support members 5 in the circumferential direction. One end of the elastic support member 5 is fixed to the mounting base 1, and the other end abuts against the outer wall of the electricity meter.

[0025] The elastic bump buffer layer 2 is made of silicone. The elastic protrusions 21 are hemispherical in shape, with a spacing of 8-10 mm between adjacent elastic protrusions 21. The elastic protrusions 21 and the elastic bump buffer layer 2 are integrally formed. The honeycomb damping core 3 is made of polyurethane foam. The damping cavity is a regular hexagonal structure. The annular damping protrusions 31 are made of rubber and are spaced apart along the axial direction of the damping cavity. The inner diameter of the annular damping protrusions 31 is smaller than the aperture of the damping cavity. The damping cavity of the honeycomb damping core 3 is filled with damping cotton. The curvature of the arc-shaped fitting groove matches the curvature of the electricity meter casing, and the inner wall of the arc-shaped fitting groove is provided with several evenly distributed micro anti-slip dimples.

[0026] The elastic support 5 is an arc-shaped elastic sheet made of spring steel and is evenly distributed along the circumference of the composite damping body. The elastic support 5 is fixed to the mounting base 1 by bolts. A rubber buffer pad is provided on the side of the free end facing the electricity meter. The rubber buffer pad is interference-fitted with the outer wall of the electricity meter.

[0027] A first adhesive layer is provided between the elastic bump buffer layer 2 and the honeycomb shock-absorbing core 3, and a second adhesive layer is provided between the honeycomb shock-absorbing core 3 and the flexible wrapping shock-absorbing layer 4. Both the first adhesive layer and the second adhesive layer are epoxy adhesives, and the connection surface between the elastic bump buffer layer 2 and the honeycomb shock-absorbing core 3 is provided with a mutually compatible sawtooth interlocking structure.

[0028] Working Principle: Initial Vibration Transmission and Preliminary Buffering: When the mounting base 1 is subjected to external vibration (such as equipment vibration, impact, etc.), the vibration energy is first transmitted to the elastic protrusion buffer layer 2 of the composite damping body. The elastic protrusions 21 of this buffer layer directly abut against the mounting base 1. Since the elastic protrusions 21 are hemispherical structures made of silicone, they have good axial elastic deformation capability. Under the action of vibration pressure, they will undergo axial compression deformation. During this process, some vibration energy is absorbed through the elastic effect of silicone molecules. At the same time, the matrix-distributed protrusions disperse the concentrated vibration impact force into multiple uniform force points, realizing the preliminary buffering and dispersion of vibration, and reducing the intensity of vibration transmission.

[0029] The remaining vibration energy, after initial buffering, is transferred to the honeycomb damping core 3. This damping core is made of polyurethane foam, and its internal hexagonal damping cavities have excellent structural stability and force transmission and dispersion capabilities, which can evenly transmit vibration energy to each damping cavity. The annular damping protrusions 31 on the inner wall of the damping cavity are made of rubber, and their inner diameter is smaller than the pore diameter of the damping cavity. When the vibration energy causes the damping cavity to deform, the annular damping protrusions 31 will rub against the inner wall of the damping cavity and the damping cotton filling, and at the same time, they will undergo elastic deformation. Through the dual effects of friction energy dissipation and deformation energy dissipation, a large amount of vibration energy is consumed. The porous structure of the polyurethane foam itself can also further absorb some vibration waves, achieving a secondary and significant attenuation of vibration energy.

[0030] The weak vibration energy, after being attenuated twice, is transmitted to the flexible wrapping damping layer 4. The arc-shaped bonding groove of this layer fits tightly with the outer shell of the electricity meter. The flexible material will adapt to the slight vibration of the electricity meter, converting the remaining vibration energy into its own flexible deformation energy and absorbing it. The micro anti-slip dimples on the inner wall increase the friction with the outer shell of the electricity meter, ensuring that there is no relative sliding between the two during vibration, avoiding additional friction loss and vibration.

[0031] Throughout the vibration transmission process, the circumferential elastic support 5 of the composite damping body functions synchronously. The arc-shaped elastic sheet made of spring steel has good radial elasticity, and the rubber buffer pad at its free end is interference-fitted with the outer wall of the energy meter to form a stable radial constraint. When the energy meter tends to displace radially due to vibration, the elastic support 5 will undergo elastic deformation, and the displacement will be limited by the reverse elastic force generated by the deformation. At the same time, the rubber buffer pad further absorbs radial vibration energy, which helps to improve the overall damping effect from the side and ensures that the energy meter is always in a stable installation position.

[0032] This utility model provides a shock-absorbing component for electricity meters, which efficiently buffers multi-frequency vibrations and comprehensively covers the shock absorption range. The composite shock-absorbing body adopts a three-layer structure, realizing graded absorption and consumption of vibration energy. The matrix of elastic protrusions in the elastic protrusion buffer layer can quickly buffer the initial impact vibration, especially showing excellent absorption capacity for high-frequency small-amplitude vibrations; the hexagonal damping cavity of the honeycomb damping core and the annular damping protrusion form a multi-damping structure, which can effectively attenuate mid-frequency vibration energy; the flexible wrapping damping layer achieves flexible transmission and absorption of low-frequency vibrations through tight fit. The synergistic effect of the three-layer structure allows the component to adapt to vibration environments of different frequencies and amplitudes, solving the problem of limited shock absorption range of traditional single structures.

[0033] The flexible, shock-absorbing layer features an arc-shaped groove that precisely matches the curvature of the meter's outer casing. Combined with micro-anti-slip dimples on the inner wall, this achieves a tight and flexible fit between the shock-absorbing components and the meter, preventing relative slippage during vibration. Circumferentially distributed elastic supports provide stable radial support to the meter. The arc-shaped elastic sheet made of spring steel combines rigidity and elasticity, limiting meter displacement and absorbing radial vibration energy through its own deformation. The interference fit of the rubber buffer further enhances the stability of the fit, effectively reducing the risk of meter loosening due to vibration.

[0034] The components are firmly connected through the first and second adhesive layers using epoxy adhesive. The serrated interlocking structure of the elastic protrusion buffer layer and the honeycomb damping core significantly improves the interfacial bonding strength, preventing interlayer delamination during vibration. The integrated molding of the elastic protrusions and buffer layer, and the bolt-fixed elastic support components enhance the overall structural stability of the components. The materials such as silicone, polyurethane foam, and spring steel all have excellent aging resistance and fatigue resistance, which can maintain elasticity and structural integrity for a long time, solving the problems of easy aging and rapid performance degradation of traditional damping components.

[0035] The component uses multi-layered shock absorption to significantly reduce the vibration energy transmitted to the inside of the electricity meter, effectively preventing the internal electronic components from loosening or being damaged due to vibration, and reducing the generation of metering errors. The flexible contact design of the flexible wrapping shock absorption layer and the rubber buffer pad avoids hard contact friction between the shock absorption component and the electricity meter shell, playing a good protective role and further ensuring the normal working condition of the electricity meter.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
