[0048] In some embodiments, the first electrode assembly E1 includes a first electrode 130 and a first terminal 150. The first electrode 130 passes through the housing 110, and a connecting piece 120 is connected to the first electrode 130 and rotates with the first electrode 130.

[0051] The voltage testing device includes an elastic probe 310, a first driving member 320, and a driving cam 330. The elastic probe 310 is mounted on the probe mounting part 210, and the first driving member 320 is mounted on the bracket 200.

[0052] In some embodiments, the bracket 200 is provided with a first drive mounting portion 220, and the first drive member 320 is mounted on the first drive mounting portion 220.

[0053] The first driving member 320 can drive the driving cam 330 and the first electrode assembly E1 to rotate. In this embodiment, the first driving member 320 can drive the first electrode 130 to rotate. The driving cam 330 has an initial position, a first voltage detection position, and a second voltage detection position.

[0054] Figure 3 This is a cross-sectional schematic diagram of an embodiment of the voltage testing plate of the present invention with the drive cam 330 in its initial position. In the initial position, the drive cam 330 abuts against the elastic probe 310, causing the elastic probe 310 to separate from both the first electrode assembly E1 and the second electrode assembly E2. In this embodiment, in the initial position, the drive cam 330 abuts against the elastic probe 310, causing the elastic probe 310 to separate from both the first terminal 150 and the second terminal 160.

[0055] Figure 4 This is a cross-sectional schematic diagram of an embodiment of the voltage testing plate of the present invention with the drive cam 330 in the first voltage testing position. In the first voltage testing position, the drive cam 330 is separated from the elastic probe 310, and the elastic probe 310 abuts against the first electrode assembly E1 to test the voltage of the first electrode assembly E1. In this embodiment, in the first voltage testing position, the drive cam 330 is separated from the elastic probe 310, and the elastic probe 310 abuts against and is electrically connected to the first terminal 150.

[0056] Figure 5 This is a cross-sectional schematic diagram of an embodiment of the voltage testing plate of the present invention with the drive cam 330 in the second voltage testing position. In the second voltage testing position, the drive cam 330 abuts against the elastic probe 310, causing the elastic probe 310 to abut against the second electrode assembly E2 to test for voltage on the second electrode assembly E2. In this embodiment, in the second voltage testing position, the drive cam 330 abuts against the elastic probe 310, causing the elastic probe 310 to abut against and electrically connect to the second terminal 160.

[0057] The control module is electrically connected to the first drive unit 320. The control module is configured to control the first drive unit 320 to drive the drive cam 330 to move to the first voltage testing position and the second voltage testing position before switching to the engaged or disengaged state, so as to complete the voltage testing of the first electrode assembly E1 and the second electrode assembly E2 respectively.

[0058] According to an embodiment of the present invention, a voltage testing plate includes a plate body 100, a support 200, a voltage testing device, and a control module. The plate body 100 includes a first electrode assembly E1 and a second electrode assembly E2. The voltage testing device includes an elastic probe 310, a first driving member 320, and a driving cam 330. The first driving member 320 can drive the driving cam 330 and the first electrode assembly E1 to rotate. The driving cam 330 has an initial position, a first voltage testing position, and a second voltage testing position. In the initial position, the driving cam 330 abuts against the elastic probe 310, causing the elastic probe 310 to separate from both the first electrode assembly E1 and the second electrode assembly E2. In the first voltage testing position, the driving cam 330 separates from the elastic probe 310, and the elastic probe 310 abuts against and is electrically connected to the first electrode assembly E1 to test for voltage in the first electrode assembly E1. In the second voltage testing position, the drive cam 330 abuts against the elastic probe 310, causing the elastic probe 310 to contact and electrically connect to the second electrode assembly E2, thereby testing the voltage of the second electrode assembly E2. The voltage-testing power plate of this embodiment has an automatic voltage testing function. Before the remote control of the plate body 100 switches it to the engaged or disengaged state, the drive cam 330 is automatically switched sequentially to the first voltage testing position and the second voltage testing position, thereby sequentially connecting the first electrode assembly E1 and the second electrode assembly E2 to the voltage testing circuit for voltage acquisition. This facilitates automatic remote control operation of the plate body 100 based on the subsequent logical judgment results. This solves the problems of potential multimeter damage, incorrect range selection, incorrect interval settings, and incorrect plate body measurements caused by the previous requirement for manual on-site measurement of the voltage of the first electrode assembly E1 and the second electrode assembly E2, followed by operation of the plate body 100. It effectively ensures the safety of operators and the circuit, and also improves work efficiency.

[0059] In the above embodiment, the first driving member 320 can drive the driving cam 330 and the first electrode 130 to rotate. When rotating, the driving cam 330 has an initial position, a first voltage-detecting position, and a second voltage-detecting position. The pressure plate body 100 has a retracted state and an engaged state. In the retracted state, the first electrode 130 rotates to disconnect from the second electrode 140; in the engaged state, the first electrode 130 rotates to electrically connect with the second electrode 140. Therefore, in the above embodiment, by using a single first driving member 320, the switching of the driving cam 330 between the initial position, the first voltage-detecting position, and the second voltage-detecting position, as well as the switching of the pressure plate body 100 between the retracted state and the engaged state, is achieved at different angles, avoiding complex coordination relationships and making control simple and reliable.

[0060] In some embodiments, after remotely engaging or disengaging the pressure plate body 100, the first electrode assembly E1 and the second electrode assembly E2 of the pressure plate body 100 can be tested again to ensure successful engagement or disengagement and improve the reliability of the device.

[0061] In some embodiments, the housing 110 includes a first housing portion 110a and a second housing portion 110b, a first electrode 130 and a second electrode 140 passing through the first housing portion 110a, and a first terminal 150 and a second terminal 160 passing through the second housing portion 110b. The second housing portion 110b is detachably connected to the first housing portion 110a.

[0062] In some embodiments, the voltage testing plate also includes a housing 400, which is detachably connected to the housing 110, and after the housing 400 is connected to the housing 110, the inner cavity of the housing 400 communicates with the inner cavity of the housing 110.

[0063] The first driving component 320 is, for example, a rotary drive motor.

[0064] In some embodiments, the probe mounting portion 210 is a probe mounting hole provided on the bracket 200. Figure 6 This is a perspective view of an elastic probe 310 in one embodiment of the voltage testing plate of the present invention. In some embodiments, the elastic probe 310 includes an elastic portion 311 and a probe portion 312. The elastic portion 311 is elastic and is mounted in a probe mounting hole, such that the probe portion 312 moves elastically around the elastic portion 311.

[0065] In some embodiments, the elastic portion 311 is, for example, a spring structure.

[0066] In some embodiments, the probe portion 312 includes a first movable arm 3121 and a second movable arm 3122 connected to each other. The first movable arm 3121 is used to contact or separate from the first electrode assembly E1; in this embodiment, the first movable arm 3121 is used to contact or separate from the first terminal 150. The second movable arm 3122 is used to contact or separate from the second electrode assembly E2; in this embodiment, the second movable arm 3122 is used to contact or separate from the second terminal 160. The drive cam 330 is capable of abutting or separating from the first movable arm 3121.

[0067] In some embodiments, the first movable arm 3121 is connected to the elastic part 311, and the second movable arm 3122 is interconnected with the first movable arm 3121 at an angle. When voltage measurement is required at the first terminal 150, the elastic probe 310 moves until the first movable arm 3121 contacts the first terminal 150, at which point the second movable arm 3122 separates from the second terminal 160. When voltage measurement is required at the second terminal 160, the elastic probe 310 moves until the second movable arm 3122 contacts the second terminal 160, at which point the first movable arm 3121 separates from the first terminal 150.

[0068] Figure 7This is a perspective view of the drive cam 330 in one embodiment of the electro-detecting power plate of the present invention. In some embodiments, the drive cam 330 is provided with a radially extending protrusion 331, which is used to abut or separate from the elastic probe 310.

[0069] like Figure 1 In some embodiments, the voltage testing plate also includes a circuit board 500, and the control module is disposed on the circuit board 500.

[0070] Figure 8 This is a perspective view of the circuit board in one embodiment of the voltage testing plate of the present invention. The circuit board 500 can be fixedly connected to the housing 110, and a first detection element 510 is provided on the circuit board 500. In some embodiments, the circuit board 500 is installed inside the housing 400. The first detection element 510 is a photoelectric switch. In other embodiments, the first detection element 510 can also be an infrared transceiver, an infrared reflector, a contact switch, etc.

[0071] like Figure 7 In some embodiments, the drive cam 330 is circumferentially arranged with a first voltage detection positioning hole 333, an initial positioning hole 332, and a second voltage detection positioning hole 334. When the drive cam 330 rotates to the initial position, the first voltage detection position, and the second voltage detection position, the initial positioning hole 332, the first voltage detection positioning hole 333, and the second voltage detection positioning hole 334 are respectively aligned with the first detection element 510.

[0072] The control module controls the first driving component 320 to move the driving cam 330 until the initial positioning hole 332 triggers the first detection element 510, causing the driving cam 330 to move to the initial position. The control module then controls the first driving component 320 to move the driving cam 330 until the first voltage detection positioning hole 333 triggers the first detection element 510, causing the driving cam 330 to move to the first voltage detection position. Finally, the control module controls the first driving component 320 to move the driving cam 330 until the second voltage detection positioning hole 334 triggers the first detection element 510, causing the driving cam 330 to move to the second voltage detection position.

[0073] By setting the first detection element 510 and setting the initial positioning hole 332, the first voltage detection positioning hole 333, and the second voltage detection positioning hole 334 on the drive cam 330, the first detection element 510 can give a timely feedback signal after the drive cam 330 rotates to the corresponding position, thereby improving the control accuracy of the first drive component 320 in the voltage detection power plate.

[0074] In some embodiments, the first driving member 320 is connected to the first electrode assembly E1 via the driving cam 330. In this embodiment, the first driving member 320 is connected to the first electrode 130 via the driving cam 330. The pressure plate body 100 has a retracted state and an engaged state. In the retracted state, the first electrode 130 rotates to disconnect from the second electrode 140. In the engaged state, the first electrode 130 rotates to be electrically connected to the second electrode 140.

[0075] like Figure 7 In some embodiments, the drive cam 330 is also provided with a retraction positioning hole 335 and a positioning positioning hole 336 along the circumferential direction. When the first electrode 130 rotates to the retraction state, the retraction positioning hole 335 of the drive cam 330 is aligned with the first detection element 510. When the first electrode 130 rotates to the positioning state, the positioning positioning hole 336 of the drive cam 330 is aligned with the first detection element 510.

[0076] The control module controls the first driving component 320 to move the driving cam 330 until the retraction hole 335 triggers the first detection element 510, causing the pressure plate body 100 to switch to the retraction state. The control module controls the first driving component 320 to move the driving cam 330 until the engagement hole 336 triggers the first detection element 510, causing the pressure plate body 100 to switch to the engagement state.

[0077] By setting the retraction positioning hole 335 and the engagement positioning hole 336 on the drive cam 330, the first drive member 320 can be stopped in time when the drive cam 330 rotates to the corresponding position, ensuring that the pressure plate body 100 can accurately reach the retraction state and the engagement state.

[0078] like Figure 1 In some embodiments, the first electrode assembly E1 includes a first electrode 130 connected to the connecting piece 120, and the power-on / off test device also includes a power-on / off wheel 340, which is drivenly connected between the drive cam 330 and the first electrode 130.

[0079] Figure 9 This is an exploded perspective view of the drive cam 330, the loading / unloading wheel 340, and the first electrode 130 in one embodiment of the electro-detecting power plate of the present invention. In some embodiments, the first electrode 130 is provided with a first transmission tooth 131, and the outer periphery of the loading / unloading wheel 340 has a second transmission tooth 341 that can mesh with the first transmission tooth 131.

[0080] In some embodiments, the retraction wheel 340 includes an annular portion 342, the inner circumferential surface of which is provided with a first boss T1. The drive cam 330 includes a mating portion 337 passing through the annular portion 342, the outer circumferential surface of which is provided with a second boss T2. The drive cam 330 rotates to cause the second boss T2 to abut or separate from the first boss T1, and drives the retraction wheel 340 to rotate when the second boss T2 abuts the first boss T1.

[0081] In the above embodiment, the drive cam 330 rotates to cause the second boss T2 to abut or separate from the first boss T1. The transmission structure between the drive cam 330 and the throwing wheel 340 can have a large idle stroke. Therefore, when the pressure plate body 100 is manually operated, the pressure plate body 100 will not drive the first driving member 320 to rotate, thus improving the user experience.

[0082] like Figure 1 In some embodiments, the voltage testing power plate also includes a circuit board 500, a grounding stake 600, and a voltage testing connection wire assembly 700. The circuit board 500 can be fixedly connected to the housing 110, and the control module is disposed on the circuit board 500.

[0083] Figure 10 This is a perspective view of a grounding stake and part of the housing 110 in one embodiment of the voltage testing power pressure plate of the present invention. The grounding stake 600 is installed on the housing 110. The voltage testing connection wire assembly 700 is electrically connected to the circuit board 500, and the voltage testing connection wire assembly 700 is electrically connected to the elastic probe 310 and the grounding stake 600 respectively.

[0084] The grounding stake 600 can be a metal block. The end of the grounding stake 600 extending out of the housing 110 and the end extending into the housing 110 respectively have wiring holes, which facilitates the electrical connection of the grounding stake 600 to the external ground wire and to the voltage detection connection wire assembly 700.

[0085] Figure 11 This is a perspective view of the voltage testing connector assembly 700 in one embodiment of the voltage testing power pressure plate of the present invention. In some embodiments, the voltage testing connector assembly 700 includes a voltage testing plug 710, a positive terminal connector 720, and a negative terminal connector 730.

[0086] The voltage test plug 710 is inserted into the circuit board 500. The positive connection wire 720 is connected to the voltage test plug 710 and electrically connected to the flexible probe 310. The negative connection wire 730 is connected to the voltage test plug 710 and electrically connected to the grounding stake 600.

[0087] In some embodiments, the circuit board 500 includes a voltage detection circuit. When the first terminal 150 or the second terminal 160 is tested for voltage, the positive connection line 720 introduces the voltage signal of the first terminal 150 or the second terminal 160 into the voltage detection circuit of the circuit board 500, while the negative connection line 730 introduces the ground voltage signal into the voltage detection circuit of the circuit board 500.

[0088] In some embodiments, the first electrode assembly E1 includes a first electrode 130 passing through the housing 110, and the pressure plate body 100 also includes a first locking nut 180, which can lock the connecting piece 120 to the first electrode 130.

[0089] like Figure 1 In some embodiments, the second electrode assembly E2 includes a second electrode 140 passing through the housing 110, and the pressure plate body 100 also includes a second locking nut 190, which is coaxially connected to the second electrode 140.

[0090] The voltage test plate also includes a locking drive assembly, which includes a second drive component 810 and a locking transmission wheel 820. The second drive component 810 drives the second electrode 140 and the second locking nut 190 to rotate through the locking transmission wheel 820.

[0091] The second locking nut 190 can be rotated to have a locked state and a loose state. When the pressure plate body 100 is in the engaged state, the connecting piece 120 and the second electrode 140 are connected. At this time, the second locking nut 190 can be rotated to the locked state to lock the connecting piece 120 and the second electrode 140.

[0092] The second driving component 810 is, for example, a rotary drive motor.

[0093] In some embodiments, the bracket 200 is provided with a second drive mounting portion 230, and the second drive member 810 is mounted on the second drive mounting portion 230.

[0094] In some embodiments, the voltage testing plate also includes a circuit board 500, which can be fixedly connected to the housing 110, and a second detection element 520 is provided on the circuit board 500.

[0095] Figure 12 This is a perspective view of the locking drive wheel in one embodiment of the voltage testing plate of the present invention. In some embodiments, the locking drive wheel 820 has a plurality of detection holes 821 arranged circumferentially. When the locking drive wheel 820 rotates, the plurality of detection holes 821 pass through the second detection element 520 in sequence at intervals, so that the second detection element 520 generates an alternating on / off signal.

[0096] The second detection element 520 can be a photoelectric switch. In some other embodiments, the second detection element 520 can also be an infrared transceiver, an infrared reflector, a contact switch, etc.

[0097] This invention also provides a voltage testing method for a voltage-testing power plate, which is applied to the voltage-testing power plate in any of the foregoing embodiments. This voltage testing method is performed before the first driving member 320 drives the first electrode assembly E1 to rotate to switch to an engaged or disengaged state. In this embodiment, the voltage testing method includes steps S110 to S150.

[0098] In step S110, the first driving member 320 drives the driving cam 330 to rotate from the initial position to the first voltage detection position.

[0099] In step S120, the first electrode assembly E1 is contacted by the elastic probe 310 and the first electrode assembly E1 is tested for voltage. In some embodiments, the first terminal 150 is contacted by the elastic probe 310 and the voltage of the first terminal 150 is measured.

[0100] In step S130, the first driving member 320 drives the driving cam 330 to rotate to the second voltage detection position.

[0101] In step S140, the second electrode assembly E2 is contacted via the elastic probe 310, and the second electrode assembly E2 is tested for voltage. In some embodiments, the second terminal 160 is contacted via the elastic probe 310, and the voltage of the second terminal 160 is measured.

[0102] In step S150, the first driving member 320 drives the driving cam 330 to rotate back to the initial position.

[0103] After the above steps, the voltage signals of the first terminal 150 and the second terminal 160 can be acquired, which facilitates the subsequent conversion, isolation, data processing and logical judgment of the acquired voltage signals.

[0104] According to the voltage testing method of the voltage testing power plate according to the embodiment of the present invention, the voltage testing power plate has an automatic voltage testing function. Before the first driving member 320 drives the first electrode assembly E1 to rotate to switch to the engaged state or disengaged state, the driving cam 330 is automatically switched to the first voltage testing position and the second voltage testing position in sequence. This allows the first electrode assembly E1 and the second electrode assembly E2 to be connected to the voltage testing circuit for voltage measurement. This facilitates the automatic remote control operation of the plate body 100 based on the judgment result of the logic judgment. This solves the problems of potential hazards such as multimeter damage, incorrect range selection, incorrect interval selection, and incorrect measurement of the plate body 100 caused by the previous need for manual on-site measurement of the voltage of the first electrode assembly E1 and the second electrode assembly E2 and operation of the plate body 100. It effectively ensures the safety of operators and the circuit and improves work efficiency.

[0105] In the above embodiment, after the voltage measurement of the first electrode assembly E1 and the second electrode assembly E2 is completed, the first driving member 320 drives the driving cam 330 to rotate back to the initial position. After the voltage test is completed, the elastic probe 310 is immediately disconnected from both the first electrode assembly E1 and the second electrode assembly E2, which can ensure the safe operation of the secondary circuit of the pressure plate body 100.

[0106] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
