[0047] Figure 1 This is an exploded perspective view of an embodiment of the voltage testing power plate of the present invention. The voltage testing power plate includes a plate body 100, a voltage testing and retraction device 200, and a control module.

[0048] The pressure plate body 100 includes a first electrode 110, a second electrode 120, and a connecting piece. The connecting piece rotates with the second electrode 120 to electrically connect or disconnect the second electrode 120 from the first electrode 110, so that the voltage-testing pressure plate can be switched between the closed state and the fully open state.

[0049] Figure 2 This is an exploded perspective view of a voltage detection device 200 in one embodiment of the voltage detection power plate of the present invention. The voltage detection device includes a housing 210 and a drive assembly DM and a voltage detection element 230 mounted on the housing 210. The drive assembly DM is connected to the voltage detection element 230 and the second electrode 120 respectively, so as to drive the second electrode 120 to rotate and drive the voltage detection element 230 to reciprocate between the first electrode 110 and the second electrode 120. The voltage detection element 230 has a first voltage detection position that is in contact with and electrically connected to the first electrode 110, a second voltage detection position that is in contact with and electrically connected to the second electrode 120, and an initial position that is not in contact with either the first electrode 110 or the second electrode 120.

[0050] The control module is electrically connected to the drive component DM. The control module is configured to control the drive component DM to rotate the second electrode 120 before switching between the closed state and the fully open state. Before switching, the control module controls the drive component DM to drive the voltage detector 230 to test the first electrode 110 at the first voltage detection position, test the second electrode 120 at the second voltage detection position, and then return to the initial position.

[0051] Figure 3 This is a cross-sectional schematic diagram of an embodiment of the voltage testing plate of the present invention, showing the voltage testing element 230 located at the first voltage testing position. Figure 4 This is a cross-sectional schematic diagram of an embodiment of the voltage testing power plate of the present invention, showing the voltage testing element 230 in a second voltage testing position. According to an embodiment of the present invention, the voltage testing power plate includes a plate body 100, a voltage testing device 200, and a control module. The voltage testing device 200 includes a housing 210 and a drive assembly DM and a voltage testing element 230 mounted on the housing 210. The voltage testing element 230 has a first voltage testing position in contact with and electrically connected to a first electrode 110, a second voltage testing position in contact with and electrically connected to a second electrode 120, and an initial position in which it is not in contact with either the first electrode 110 or the second electrode 120. The control module is configured to control the drive assembly DM to rotate the second electrode 120 before switching between a closed state and a fully open state, and to control the drive assembly DM to drive the voltage testing element 230 to test the first electrode 110 in the first voltage testing position, test the second electrode 120 in the second voltage testing position, and then return to the initial position. The aforementioned voltage-testing power plate can test the first electrode 110 and the second electrode 120 sequentially before putting on or taking off the plate, effectively ensuring the personal safety of the operator and improving the convenience of voltage testing the plate body 100.

[0052] In some embodiments, the voltage testing plate further includes a circuit board 300. The circuit board 300 includes a control module and a voltage testing module. The control module is electrically connected to the drive assembly DM, and the voltage testing module is electrically connected to the voltage testing element 230. The control module is configured to control the drive assembly DM to rotate the second electrode 120 before switching between a closed state and a fully open state, and to control the drive assembly DM to drive the voltage testing element 230 to test the first electrode 110 at a first voltage testing position, test the second electrode 120 at a second voltage testing position, and then return to its initial position. In the first voltage testing position, the voltage testing element 230 connects the first electrode 110 to the voltage testing module, enabling the voltage testing module to collect voltage information from the first electrode 110. In the second voltage testing position, the voltage testing element 230 connects the second electrode 120 to the voltage testing module, enabling the voltage testing module to collect voltage information from the second electrode 120.

[0053] According to an embodiment of the present invention, the voltage-testing power plate has an automatic voltage testing function. When the power plate body 100 is remotely engaged or disengaged, it automatically connects the first electrode 110 and the second electrode 120 of the power plate body 100 to the voltage testing module for voltage collection and testing, performs logical judgment, and then automatically performs remote control operation of the power plate body 100 based on the judgment result. This solves the problems of potential hazards such as multimeter damage, incorrect range selection, incorrect interval operation, and incorrect measurement of the power plate body 100 caused by the previous need for manual on-site measurement of terminal voltage and operation of the power plate body 100. It effectively ensures the safety of operators and lines, and also improves work efficiency.

[0054] In some embodiments, the pressure plate body 100 further includes a handle 140, which is an insulator and connected to the second electrode 120. This allows the second electrode 120 to be rotated by rotating the handle 140, enabling manual engagement and disengagement of the pressure plate body 100. The voltage-testing pressure plate according to embodiments of the present invention supports manual operation and can automatically correct any abnormalities in manual operation, effectively preventing abnormalities in the pressure plate body 100.

[0055] like Figure 2 In some embodiments, the housing 210 includes a first housing portion 211 and a second housing portion 212 that are detachably connected to each other.

[0056] like Figure 1 In some embodiments, the voltage testing plate also includes a housing 400. The circuit board 300 and the voltage testing device 200 are installed inside the housing 400, while a portion of the plate body 100 is located outside the housing 400, and the first electrode 110 and the second electrode 120 extend into the housing 400. In some embodiments, the housing 400 includes a base 410 and a cover 420 that are detachably connected to each other.

[0057] Figure 5 This is a perspective view of the voltage testing element 230 in one embodiment of the voltage testing plate of the present invention. In some embodiments, the voltage testing element 230 includes a rack 231, a first probe 233, and a second probe 234. The rack 231 extends between the first electrode 110 and the second electrode 120. The first probe 233 and the second probe 234 are located at opposite ends of the rack 231. In the first voltage testing position, the first probe 233 contacts and is electrically connected to the first electrode 110. In the second voltage testing position, the second probe 234 contacts and is electrically connected to the second electrode 120.

[0058] In some embodiments, the first probe 233 is elastically and retractably disposed on the rack 231.

[0059] In some embodiments, the first probe 233 is mounted in the rack 231 by springs 232. Since the first probe 233 can elastically extend and retract relative to the rack 231, when the voltage detector 230 is in the first voltage detection position and the second voltage detection position, the first probe 233 can make close contact with the first electrode 110 and the second probe 234 can make close contact with the second electrode 120, respectively, ensuring the reliability of voltage detection of the first electrode 110 and the second electrode 120.

[0060] In some embodiments, the voltage detection device 200 further includes a positioning post 250, which is fixedly disposed in the housing 210. The side wall of the rack 231 is provided with a positioning groove 2311. When the voltage detection component 230 moves to the initial position, the positioning post 250 is engaged in the positioning groove 2311.

[0061] In some embodiments, the positioning post 250 is a ball-head plunger, and the positioning groove 2311 is a recessed structure that matches a portion of the outer periphery of the positioning post 250. When the voltage detector 230 moves to its initial position, a portion of the circumferential side of the positioning post 250 engages with the positioning groove 2311. In the non-voltage detection state, the positioning post 250 engages with the positioning groove 2311, allowing the voltage detector 230 to be stably positioned in its initial position, thus preventing the voltage detector 230 from contacting the first electrode 110 or the second electrode 120 in the non-voltage detection state.

[0062] In some embodiments, the drive assembly DM includes a power component 220, a voltage detection drive component, and an engagement / disengagement drive component. The voltage detection drive component drives the voltage detection component 230 to the power component 220, and the engagement / disengagement drive component drives the second electrode 120 to the power component 220.

[0063] According to an embodiment of the present invention, the voltage-detecting power plate utilizes a power component 220 to switch between the initial position, the first voltage-detecting position, the first voltage-detecting position, the closed position, and the fully open position at different angles, avoiding complex coordination relationships and making the control simple and reliable.

[0064] In some embodiments, the voltage detection drive includes a voltage detection gear 240, which can mesh with the voltage detection element 230.

[0065] Figure 6 This is a perspective view of the detection gear 240 in one embodiment of the voltage-detecting power plate of the present invention. In some embodiments, the voltage-detecting gear 240 has a plurality of position feedback slots arranged circumferentially at intervals on one side of its outer periphery, and a transmission tooth 242 for meshing with the voltage-detecting element 230 on the other side. The voltage-detecting power plate also includes a first photoelectric sensor 310 electrically connected to a control module. The control module is configured to trigger the feedback signal generated by the first photoelectric sensor 310 based on a specific position feedback slot, and control the voltage-detecting element 230 to move to the position corresponding to the position feedback slot. In some embodiments, the first photoelectric sensor 310 is disposed on a circuit board 300.

[0066] In this embodiment, the position feedback slot is a U-shaped slot. In this embodiment, the first photoelectric sensor 310 is a U-shaped photoelectric sensor.

[0067] In some embodiments, the plurality of position feedback slots include a first voltage detection position slot 243b, an initial position slot 243a, and a second voltage detection position slot 243c, with the first voltage detection position slot 243b and the second voltage detection position slot 243c located on both sides of the initial position slot 243a. In some embodiments, adjacent position feedback slots are spaced apart by an angle of 30° along the rotation direction of the voltage detection gear 240.

[0068] The control module controls the power component 220 to drive the electric detector 230 to move until the initial position slot 243a triggers the first photoelectric sensor 310, causing the electric detector 230 to move to the initial position.

[0069] The control module controls the power component 220 to drive the voltage detector 230 to move until the first voltage detector position slot 243b triggers the first photoelectric sensor 310, causing the voltage detector 230 to move to the first voltage detector position.

[0070] The control module controls the power component 220 to drive the voltage detector 230 to move until the second voltage detector position slot 243c triggers the first photoelectric sensor 310, causing the voltage detector 230 to move to the second voltage detector position.

[0071] By setting a position feedback groove on the outer periphery of the voltage testing gear 240 and setting a first photoelectric sensor 310 that cooperates with it, the rotation of the power component 220 can be precisely and automatically controlled through the feedback signal, so that the power component 220 drives the voltage testing component 230 to move accurately to the initial position, the first voltage testing position or the second voltage testing position, thereby accurately realizing the voltage testing operation of the pressure plate body 100.

[0072] In some embodiments, the deployment / retraction drive includes a drive wheel 260 and a rotating wheel 270. The drive wheel 260 is coaxially arranged with the power component 220 and is connected in transmission. The rotating wheel 270 is coaxially arranged with the second electrode 120, and the drive wheel 260 and the rotating wheel 270 are connected in transmission.

[0073] As mentioned above, in some embodiments, the voltage detection drive includes a voltage detection gear 240, which is connected to the drive wheel 260 in a transmission manner.

[0074] Figure 7 This is an exploded perspective view of the voltage testing gear 240 and the drive wheel 260 in one embodiment of the voltage testing plate of the present invention. In some embodiments, the voltage testing gear 240 includes an axially outwardly extending protrusion 241, and the outer peripheral surface of the protrusion 241 is provided with a first abutting protrusion T1. In some embodiments, the drive wheel 260 includes a hollow portion 261, the inner peripheral surface of the hollow portion 261 is provided with a second abutting protrusion T2, and the protrusion 241 extends into the hollow portion 261.

[0075] When the power component 220 drives the voltage detector 230 to reciprocate, the first abutment protrusion T1 and the second abutment protrusion T2 separate when the voltage detector 230 switches between the first voltage detector position and the second voltage detector position. When the power component 220 drives the second electrode 120 to rotate, the first abutment protrusion T1 and the second abutment protrusion T2 abut against each other, causing the drive wheel 260 to rotate with the voltage detector gear 240.

[0076] like Figure 2 In some embodiments, the voltage detection drive also includes a positioning wheel 280 and a rotation control wheel 290. The positioning wheel 280 is connected between the drive wheel 260 and the rotating wheel 270. The rotation control wheel 290 is coaxially connected with the positioning wheel 280 and is located outside the housing 210.

[0077] Figure 8 This is a perspective view of the rotation control wheel 290 in one embodiment of the electro-detectable power plate of the present invention. The rotation control wheel 290 has two detection grooves 291 spaced apart circumferentially on its outer periphery. The electro-detectable power plate also includes a second photoelectric sensor 320 electrically connected to the control module. The control module is configured to control the second electrode 120 to rotate to an engaged or fully disengaged state based on the feedback signal generated by the second photoelectric sensor 320 triggered by the detection grooves 291. In some embodiments, the second photoelectric sensor 320 is disposed on a circuit board 300.

[0078] In this embodiment, the second photoelectric sensor 320 is a U-shaped photoelectric sensor.

[0079] In some embodiments, the two detection slots 291 are spaced 90° apart from each other along the rotation direction of the rotation control wheel 290.

[0080] In the above embodiment, by setting the second photoelectric sensor 320 and the rotation control wheel 290, the rotation of the power component 220 can be accurately and automatically controlled by the power plate for testing, so that the power component 220 drives the second electrode 120 to move accurately to the closed position or the fully open position, thereby accurately realizing the deployment and retraction operation of the plate body 100.

[0081] This invention also provides a control method for a voltage-detecting power plate, which is used for a voltage-detecting power plate in any of the foregoing embodiments. The control method includes steps S110 to S140.

[0082] In step S110, the power test plate is in the first state. In response to the received switching command, it controls the drive component DM to start rotating. The first state is either the closed state or the fully open state.

[0083] In step S120, the control drive component DM drives the voltage detector 230 to the first voltage detection position to detect voltage on the first electrode 110.

[0084] In step S130, the control drive component DM drives the voltage detector 230 to the second voltage detection position to detect voltage on the second electrode 120.

[0085] The order of steps S120 and S130 is not limited. In some embodiments, step S120 is performed first and then step S130 is performed. In other embodiments, step S130 is performed first and then step S120 is performed.

[0086] In step S140, after the first electrode 110 and the second electrode 120 are tested for voltage respectively, the control drive component DM drives the second electrode 120 to rotate so that the voltage-testable power plate switches to the second state, which is the other of the fully separated state and the closed state.
