Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meters, in particular to a novel split-type single-phase intelligent electric energy meter for testing new energy batteries. Background Art

[0002] The new split-type single-phase smart energy meter for new energy battery testing is an intelligent energy metering device designed specifically for new energy battery charging and discharging test scenarios. The split structure separates the metering detection module from the display module. The former is centrally installed in safe areas such as distribution boxes, and the latter can be flexibly deployed in the test area. The security of the metering module is improved through physical isolation to avoid data tampering or equipment damage caused by user accidental touch. It is optimized for the charging and discharging characteristics of new energy batteries and has high-precision measurement capabilities. It can accurately capture key parameters such as battery energy flow, voltage, current and power, and adapt to dynamic electricity prices and variable working conditions. Through the deep integration of split structure and intelligent functions, high-precision and high-reliability testing of the charging and discharging process of new energy batteries is achieved. Its role is not limited to data collection, but also extends to performance evaluation, system integration and technology development promotion. It is an important innovation in key testing equipment in the new energy field.

[0003] In the prior art, new split-type single-phase smart energy meters for new energy battery testing are frequently plugged and unplugged, or mobile devices are used, which stresses the wires. Long-term pulling causes metal fatigue within the wires, leading to signal or power interruptions. During new energy battery testing, dynamic loads, high-frequency charging and discharging, or mobile equipment installation generate vibrations that repeatedly stress the wires. During electric vehicle testing, connectors can become loose at the caulking due to vibration, causing circuit breakage and voltage anomalies. During new energy battery testing, the site is crowded and busy, and someone might accidentally trip over a cable on the ground or rub their elbow against it while picking up something, causing a sudden tug, which can cause a wire to become loose. If the meter's terminals are not tightened, a slight pull can reduce the "virtual connection" between the cable and the terminal, increasing the resistance. This is equivalent to adding an "invisible resistor" to the circuit, resulting in inaccurate current and voltage measurements, and ultimately inaccurate power and energy calculations. If the cable is tugged violently at the connection to the meter, the terminal may be torn from the meter case or even deform the circuit board inside the meter, damaging the meter. Summary of the Invention

This not only strengthens the fixing effect by increasing friction, but also utilizes the flexible deformation of the protrusion block to buffer the extrusion force, avoiding damage to the cable due to hard contact, significantly improving the tensile strength and long-term stability of the cable connection in new energy battery testing, and effectively preventing leakage or equipment damage caused by loose cables.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figures 1-9 As shown, the novel split-type single-phase smart energy meter for new energy battery testing according to the present invention includes a main housing assembly 100, the upper end of which is fixedly connected to a mounting base 200, one end of which is provided with a buffer mechanism 300 for flexibly absorbing the tension of the cable, the buffer mechanism 300 including a rotating shaft 301, and an extrusion block 302 eccentrically connected to the surface of the rotating shaft assembly 301; The extrusion block 302 has a chamber for accommodating a cable connector. The extrusion block 302 forms an elastic swing structure with the base 200 through the rotating shaft 301. The extrusion block 302 rotates eccentrically around the rotating shaft assembly 301. The extrusion block 302 has a chamber inside for accommodating the connector of the new energy battery test cable. A fixing mechanism 400 is provided inside the extrusion block 302 to limit the joint of the cable. The fixing mechanism 400 includes an annular airbag 401. One end of the extrusion block 302 is provided with a tightening mechanism 500 for tightening the cable joint, and a second sleeve 600 is fixedly connected to the surface of the base 200; The extrusion block 302 cooperates with the second sleeve 600 fixed on the surface of the base 200 to further fix the end of the cable away from the connector. The second sleeve 600 also limits the position of the cable.

[0021] Specifically, a first hollow groove 201 is defined inside the base 200 , and the extrusion block 302 is movably disposed in the first hollow groove 201 via the rotating shaft 301 . The first hollow groove 201 and the extrusion block 302 form a clearance fit. Furthermore, the buffer mechanism 300 includes a rotating shaft 301, which is elastically connected to the base 200 through a torsion spring. A second hollow groove 3011 is opened inside the rotating shaft 301, and a hose 304 is fixedly connected to the inside of the rotating shaft 301. A bolt 303 is engaged with the inside of the extrusion block 302, and a second wiring piece 405 electrically connected to the fixing mechanism 400 is provided at the end of the bolt 303; the cable is inserted from the lower end of the second sleeve 600, and the cable is passed out from the upper end of the second sleeve 600 and bent and inserted into the annular airbag 401. At this time, the bolt 303 is rotated to engage with the extrusion block 302, and the bolt 303 will drive the second wiring piece 405 to move toward one end of the first wiring piece 404. The inward movement of the second wiring piece 405 will cooperate with the first wiring piece 404 to fix the cable connector.

[0022] In addition, when the cable is pulled, the cable will pull the extrusion block 302 to rotate eccentrically around the shaft 301. The eccentric rotation of the extrusion block 302 will drive the shaft 301 to rotate, and the rotation of the shaft 301 will compress the torsion spring inside the extrusion block 302. The rotation of the shaft 301 compresses the torsion spring, thereby buffering the tension when the cable is pulled, and preventing the cable from being directly broken or falling off. The mechanical buffering design of the extrusion block 302 driving the shaft 301 to compress the torsion spring by eccentric rotation realizes the dynamic absorption and protection of the cable tension. When the cable is pulled, the eccentric rotation of the extrusion block 302 triggers the deformation of the torsion spring, and converts the instantaneous tension into elastic potential energy, effectively preventing the cable from being directly broken or the connector from falling off. At the same time, the reset characteristic of the torsion spring ensures that the cable automatically returns to a stable state after being subjected to force, thereby improving the reliability of the cable connection in the new energy battery test and significantly reducing the risk of equipment failure.

[0023] It should be noted that the fixing mechanism 400 includes an annular airbag 401, which is fixedly connected to the inside of the extrusion block 302. An elastic rubber tube 402 is fixedly connected to the outer surface of the annular airbag 401, and a one-way pressure relief rubber plug 403 is tightly fitted inside the elastic rubber tube 402. A first wiring piece 404 is fixedly connected to the inner surface of the annular airbag 401, and a second wiring piece 405 is also fixedly connected to the inner surface of the annular airbag 401. The elastic rubber tube 402 and the annular airbag 401 form a sealed connection to form a pressure-adjustable flexible limit assembly. When the rotating shaft 301 rotates, the guide rod 504 will be driven to rotate. The rotation of the guide rod 504 will drive the rotating pin 503 to move toward one end. The movement of the rotating pin 503 to one end will drive the sliding rod 502 to move toward one end. The movement of the sliding rod 502 to one end will drive the piston 507 to move toward one end. The initial position of the piston 507 is close to one end of the sliding rod 502. The outside air enters the interior of the first sleeve 501 through the opening 5011. The movement of the piston 507 to one end will compress the air inside the first sleeve 501. The air inside the first sleeve 501 The air in the connecting tube 505 enters the second hollow groove 3011 in the rotating shaft 301 through the one-way valve 506. The air in the second hollow groove 3011 enters the annular airbag 401 through the hose 304. The annular airbag 401 is filled with air and expands. The expansion of the annular airbag 401 tightens the cable joint, so that the first terminal piece 404 and the second terminal piece 405 fit tightly with the cable joint, avoiding the cable joint from falling off and causing leakage, affecting the test of the new energy battery of the single-phase smart energy meter, and even The single-phase smart energy meter is damaged; when the air pressure in the annular airbag 401 reaches a certain value, the pressure will be released through the one-way pressure relief rubber plug 403 on the elastic rubber tube 402; while the rotating shaft 301 rotates, it will also drive the piston 507 to compress the air to inflate the annular airbag 401 through the one-way valve 506, so that the annular airbag 401 expands and tightens the cable joint, ensuring that the first wiring piece 404 and the second wiring piece 405 are tightly fitted to the cable joint to prevent the cable joint from falling off and leaking; when the air pressure reaches the threshold, the one-way pressure relief rubber plug 403 automatically releases the pressure to avoid overpressure damage.

[0024] It is worth mentioning that the tightening mechanism 500 comprises a first sleeve 501 fixedly connected with the base 200, a sliding rod 502 slidingly connected in the first sleeve 501, an opening 5011 formed in the first sleeve 501, a rotating pin 503 rotatably connected to one end of the sliding rod 502, a guide rod 504 attached to one end of the rotating pin 503, the guide rod 504 being fixedly connected with the rotating shaft 301, a connecting pipe 505 fixedly connected to the bottom surface of the end of the first sleeve 501 away from the sliding rod 502, a one-way valve 506 fixedly connected in the connecting pipe 505, a piston 507 slidingly connected in the first sleeve 501, and the piston 507 being fixedly connected to one end of the sliding rod 502; while the rotating shaft 301 rotates to drive the eccentric rotation of the extrusion block 302, the eccentric rotation of the extrusion block 302 also gradually extrudes the second sleeve 600, the extrusion of the second sleeve 600 by the eccentric rotation of the extrusion block 302 cooperates with the base 200, the second sleeve 600 is clamped by the extrusion block 302 and the base 200, the extrusion of the second sleeve 600 by the eccentric rotation of the extrusion block 302 further drives the convex block 601 to adhere to the surface of the cable, and the second sleeve 600 drives the convex block 601 to further fix the end of the cable away from the connector, so as to avoid the leakage of electricity or the damage of the electric energy meter caused by the direct pulling of the cable connector.

[0025] Specifically, the inner wall surface of the second sleeve 600 is provided with a plurality of convex blocks 601, and the convex blocks 601 are arranged in an annular array on the inner wall of the second sleeve 600; a plurality of convex blocks 601 are arranged in the second sleeve 600, and the convex blocks 601 can buffer the extrusion force between the second sleeve 600 and the cable; the second sleeve 600 is clamped by the eccentric rotation of the extrusion block 302, so that the end of the cable away from the connector is fixed twice by the extrusion block 302, the second sleeve 600 is extruded by the extrusion block 302 and the base 200, the convex block 601 is driven to adhere to the surface of the cable, the fixing effect is strengthened by increasing the friction, the extrusion force is buffered by the flexible deformation of the convex block 601, the cable is prevented from being damaged by hard contact, the tensile strength and long-term stability of the cable connection in the new energy battery test are significantly improved, and the leakage or damage of the equipment caused by the loosening of the cable is effectively prevented.

[0026] Working principle: when the present application is used, the cable is inserted into the second sleeve 600 from the lower end of the second sleeve 600, the cable is inserted into the annular air bag 401 after being bent and being inserted out of the upper end of the second sleeve 600, the split structure separates the metering detection module and the display module, the former is concentratedly installed in a safe area such as a distribution box, and the latter can be flexibly deployed in a test area, the safety of the metering module is improved by physical isolation, and data tampering or equipment damage caused by user misoperation is avoided.

[0027] At this time, the bolt 303 is rotated to engage with the extrusion block 302, and the bolt 303 drives the second connecting piece 405 to move toward one end of the first connecting piece 404. The inward movement of the second connecting piece 405 cooperates with the first connecting piece 404 to fix the cable connector.

[0028] When the cable is pulled, the cable will pull the extrusion block 302 to rotate eccentrically around the shaft 301. The eccentric rotation of the extrusion block 302 will drive the shaft 301 to rotate. The rotation of the shaft 301 will compress the torsion spring inside the extrusion block 302. The rotation of the shaft 301 compresses the torsion spring, thereby buffering the tension when the cable is pulled, and preventing the cable from being directly broken or falling off. The mechanical buffering design of the extrusion block 302 driving the shaft 301 to compress the torsion spring by eccentric rotation realizes dynamic absorption and protection of cable tension. When the cable is pulled, the eccentric rotation of the extrusion block 302 triggers the deformation of the torsion spring, converting the instantaneous tension into elastic potential energy, effectively preventing the cable from being directly broken or the connector from falling off. At the same time, the reset characteristic of the torsion spring ensures that the cable automatically returns to a stable state after being subjected to force, thereby improving the reliability of cable connection in new energy battery testing and significantly reducing the risk of equipment failure.

[0029] When the rotating shaft 301 rotates, the guide rod 504 is driven to rotate. The rotation of the guide rod 504 drives the rotating pin 503 to move toward one end. The movement of the rotating pin 503 to one end drives the sliding rod 502 to one end. The movement of the sliding rod 502 to one end drives the piston 507 to one end. The initial position of the piston 507 is at one end close to the sliding rod 502. The outside air enters the interior of the first sleeve 501 through the opening 5011. The movement of the piston 507 to one end compresses the air inside the first sleeve 501. The air inside the first sleeve 501 enters the interior of the connecting pipe 505. The air inside the connecting pipe 505 enters the second hollow groove 3011 inside the rotating shaft 301 through the one-way valve 506. The air in the second hollow groove 3011 enters the annular airbag 401 through the hose 304. The annular airbag 401 is filled with air and expands. The expansion of the annular airbag 401 tightens the joint of the cable, so that the first The wiring piece 404 and the second wiring piece 405 fit tightly with the cable joint to prevent the cable joint from falling off and causing leakage, affecting the test of the new energy battery of the single-phase smart electricity meter, or even damaging the single-phase smart electricity meter. When the air pressure in the annular airbag 401 reaches a certain value, the pressure will be released through the one-way pressure relief rubber plug 403 on the elastic rubber tube 402; when it is necessary to remove the cable joint, just pull the one-way pressure relief rubber plug 403 out of the elastic rubber tube 402. At this time, the gas in the annular airbag 401 will be discharged from the elastic rubber tube 402. When the rotating shaft 301 rotates, it will also drive the piston 507 to compress the air and inflate the annular airbag 401 through the one-way valve 506, causing the annular airbag 401 to expand and tighten the cable joint, ensuring that the first wiring piece 404 and the second wiring piece 405 are tightly fitted with the cable joint to prevent the cable joint from falling off and causing leakage; when the air pressure reaches the threshold, the one-way pressure relief rubber plug 403 automatically releases the pressure to avoid overpressure damage.

[0030] While the rotation of the rotating shaft 301 drives the extrusion block 302 to rotate eccentrically, the eccentric rotation of the extrusion block 302 will gradually squeeze the second sleeve 600. The eccentric rotation of the extrusion block 302 squeezes the second sleeve 600 to cooperate with the base 200. The extrusion block 302 cooperates with the base 200 to clamp the second sleeve 600. The eccentric rotation of the extrusion block 302 squeezes the second sleeve 600 and drives the protruding block 601 to fit the surface of the cable. The second sleeve 600 drives the protruding block 601 to further fix the end of the cable away from the connector, avoiding the cable connector from being directly pulled to cause leakage or even damage the electricity meter. The new energy battery is tested by the new split single-phase smart electricity meter.

[0031] Several protruding blocks 601 are provided inside the second sleeve 600. The protruding blocks 601 can buffer the squeezing force between the second sleeve 600 and the cable, and can also increase the friction between the second sleeve 600 and the cable. The second sleeve 600 is clamped by the eccentric rotation of the squeezing block 302, so that the squeezing block 302 can perform secondary fixation on the end of the cable away from the connector. The squeezing block 302 and the base 200 cooperate to squeeze the second sleeve 600, driving the protruding blocks 601 to fit the surface of the cable, which not only strengthens the fixing effect by increasing friction, but also uses the flexible deformation of the protruding blocks 601 to buffer the squeezing force, avoiding hard contact and damaging the cable, significantly improving the tensile strength and long-term stability of the cable connection in new energy battery testing, and effectively preventing leakage or equipment damage caused by loose cables.
