In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] like Figures 1 to 16As shown, the electric operating device 100 of the present invention includes an outer shell 1, an operating panel 3, a connecting component 4, a control circuit board 5, a padlock plate 6, a padlock baffle 7, a manual operating panel 8, a linkage part 9, a plastic liner 10, a separation and combination indicating slide plate 101 and a driving component 102.

[0043] The electric operating device 100 is used to drive the switch handle 2 on the circuit breaker to open or close the circuit breaker. The switch handle 2 is shown in the figure to facilitate understanding of the matching relationship between the electric operating device 100 and the circuit breaker, and does not mean that the switch handle 2 belongs to the electric operating device 100.

[0044] like Figures 1 to 4 As shown, the outer shell 1 includes a display cover 11 arranged on one side, a first cover body 12 extending from the display cover 11 toward one side, and a second cover body 13 extending from the first cover body 12 toward a side away from the display cover 11, and the second cover body 13 protrudes from the first cover body 12 in a horizontal direction to form a mounting step 14.

[0045] The plastic liner 10 is inside the outer shell 1 .

[0046] In this embodiment, the direction perpendicular to the display cover 11 is defined as the vertical direction, the extending direction of the display cover 11 or the extending direction parallel to the display cover 11 is defined as the horizontal direction, and the direction of the electric operating device 100 toward the display cover 11 is defined as the upper direction, and the direction away from the display cover 11 is defined as the lower direction. Such definition does not represent the position relative to the ground during actual installation or use, and is not limited to this.

[0047] The display cover 11 is provided with a display hole 111, an operation hole 112 and a moving slot 113; the lower side of the display cover 11 is recessed upward to provide a track slot 114. In this embodiment, the track slot 114 does not penetrate the display cover 11, but the present invention is not limited thereto.

[0048] If the hole-opening installation is adopted, in combination with the protective panel, the first cover body 12 can be protruded out of the protective panel to expose the display cover 11 and the installation cabinet, while the second cover body 13 is hidden in the cabinet, and the installation step 14 plays a limiting role, which can improve the protection level.

[0049] An identification icon 115 may also be provided on the outward side of the display cover 11 to indicate that the color, shape, etc. displayed in the display hole 111 correspond to the state of the electric operating device 100. Generally speaking, the electric operating device 100 has at least three states: closed (ON), opened (OFF), and tripped (TRIPPED), wherein the closed and opened states correspond to the closed and opened states of the circuit breaker and the electric operating device 100, and when the circuit breaker is opened, the electric operating device 100 may be in a tripped state, which can be understood by those skilled in the art and will not be elaborated here.

[0050] like Figures 5 to 7 As shown, the operating panel 3 is arranged in the outer shell 1, and is used to manually drive the connecting assembly 4 to work. In this embodiment, a key hole 31 is arranged on the operating panel 3, and is used for the user to insert a key to operate the opening and closing of the switch.

[0051] The operating hole 112 is disposed directly above the operating panel 3 to expose the key hole 31 .

[0052] like Figure 1 , 3 As shown in 12, the manual operating panel 8 is provided with an exposed groove 81, and the manual operating panel 8 is provided with a hand-held protrusion 82 protruding upward. The hand-held protrusion 82 is inserted into the movable groove 113 along the vertical direction, and the manual operating panel 8 can be moved in the horizontal direction by the user's hand-held operation.

[0053] The manual operation panel 8 is disposed between the display cover 11 and the operation panel 3. The manual operation panel 8 has a first position that blocks between the operation hole 112 and the manual operation panel 8, and a second position that moves in the horizontal direction relative to the first state. When the manual operation panel 8 is in the second position, the exposure slot 81 is located between the operation hole 112 and the manual operation panel 8. If the padlock baffle 7 does not block the exposure slot 81, the user can operate the operation panel 3 through the exposure slot 81.

[0054] like Figure 1-3 , Figure 6 , Fig.14 As shown, a padlock hole 61 is provided at one end of the padlock plate 6 close to the display cover 11, and the padlock plate 6 has a received state and a padlocked state. When the padlock plate 6 is in the received state, the padlock hole 61 is located inside the outer shell 1; when the padlock plate 6 is in the padlocked state, the padlock plate 6 protrudes out of the outer shell 1, and the padlock hole 61 is exposed to the outside of the outer shell 1.

[0055] A reset plate 110 is provided on the plastic liner 10, and a reset tension spring 62 is provided on the padlock plate 6. The reset tension spring 62 connects the padlock plate 6 and the reset plate 110. When the padlock plate 6 protrudes out of the outer shell 1, the reset tension spring 62 is in a stretched state. When the external force is lost, the reset tension spring 62 can drive the padlock plate 6 to automatically change to a retracted state.

[0056] A hook 63 is protruded from the padlock plate 6 , and one end of the reset spring 62 is clamped with the hook 63 .

[0057] The padlock plate 6 is provided with a guide groove 64 extending in the vertical direction, and the plastic liner 10 is provided with a guide portion 120 protruding through the guide groove 64. The end of the guide portion 120 is larger than the width of the guide groove 64 to prevent the guide portion 120 from detaching from the padlock plate 6.

[0058] One end of the guide groove 64 is provided with a mounting hole 641 for the guide portion 120 to pass through. When the guide portion 120 is installed, the guide portion 120 passes through the mounting hole 641 .

[0059] In this embodiment, when the circuit breaker is closed, the padlock plate 6 must be in the receiving state, and when the circuit breaker is opened, the padlock plate 6 may be in the receiving state or the padlocked state. Whether to padlock or not needs to be selected by the user according to the actual situation. In order to achieve this effect, this embodiment is configured as follows:

[0060] A resisting block 65 is disposed at the other end of the padlock plate 6 away from the padlock hole 61 , wherein the padlock hole 61 is close to the display cover 11 , and the resisting block 65 is away from the display cover 11 .

[0061] The abutting block 65 is rotatably arranged relative to the padlock plate 6 .

[0062] The connecting assembly 4 includes a driving motor 41, a gear set 42, a cam 43, a slider 44, and a slide rail 45. The connecting assembly 4 is used to electrically drive the switch handle 2 to work;

[0063] like Figures 5 to 9 As shown, the gear set 42 is connected to the drive motor 41 and the cam 43, the cam 43 is connected to the gear set 42 and the slider 44, the drive motor 41 drives the gear set 42 to rotate, so as to drive the cam 43 to rotate, and the cam 43 drives the slider 44 to move, and when the electric operating device 100 cooperates with the circuit breaker, the slider 44 is connected to the switch handle 2, and the slider 44 slides in the horizontal direction to drive the switch handle 2 to rotate. In this way, the switch handle 2 can be driven to rotate by the operation of the drive motor 41.

[0064] At the same time, the connecting component 4 can connect the operating disk 3 and the switch handle 2, and the operating disk 3 rotates axially to drive the switch handle 2 to move through the connecting component 4 to realize the opening or closing of the circuit breaker; the implementation method of this embodiment is that the operating disk 3 is connected to the gear group 42 and the cam 43, and the drive motor 41 has a clutch function. When there is no power supply, the operating disk 3 can be rotated to achieve the effect of driving the gear group 42 to rotate, the cam 43 to rotate and the slider 44 to move.

[0065] The slider 44 is slidably disposed relative to the slide rail 45. The slide rail 45 extends in a horizontal direction. In this embodiment, there are two slide rails 45 disposed at intervals.

[0066] When the padlock plate 6 is in the receiving state, the slider 44 can restrict the padlock plate 6 from hanging up in the vertical direction, and when the padlock plate 6 is padlocked, the padlock plate 6 restricts the slider 44 from sliding to restrict the circuit breaker from closing.

[0067] Specifically, the abutment block 65 has a first state and a second state. In this embodiment, the first state and the second state are different angles of rotation relative to the padlock plate 6. When the circuit breaker is closed, the padlock hole 61 is located in the outer shell 1, that is, it is in a receiving state, and the abutment block 65 is in the first state, and the abutment block 65 abuts against the slider 44 in the vertical direction to limit the padlock plate 6 from moving in the vertical direction; when the circuit breaker is opened and the padlock plate 6 protrudes out of the outer shell 1 for padlocking, it is in the padlocking state, and the slider 44 moves in the horizontal direction to make way for the abutment block 65, and the abutment block 65 is in the second state, and the abutment block 65 abuts against the slider 44 in the horizontal direction to limit the slider 44 from moving in the horizontal direction.

[0068] The abutting block 65 is provided with a torsion spring 66 . When the abutting block 65 rotates from the first state to the second state, the abutting block 65 is driven by the padlock plate 6 to move upward for a distance, and the abutting block 65 rotates under the action of the torsion spring 66 .

[0069] When the abutting block 65 changes from the second state to the first state, the abutting block 65 is driven by the padlock plate 6 to move downward for a distance, and the abutting block 65 abuts against the slide rail 45 and rotates relative to the padlock plate 6 .

[0070] The lower end of the slider 44 is provided with a yielding portion 441 for resisting and limiting the resisting block 65 . When the resisting block 65 is in the first state, the resisting block 65 resists the yielding portion 441 of the slider 44 .

[0071] In this embodiment, when the electric operating device 100 is closed, the slider 44 can limit the padlock plate 6 from hanging up, and when the padlock plate 6 is locked, the abutment block 65 limits the slider 44 from sliding to avoid closing, which is safer to use.

[0072] like Figures 1 to 6 , Fig.11 , Fig.14 As shown, the padlock baffle 7 is slidably arranged in the horizontal direction. When the padlock plate 6 is padlocked, the padlock baffle 7 is blocked between the operating hole 112 and the manual operating plate 8. When the circuit breaker is closed, the padlock baffle 7 leaves the operating hole 112 and the manual operating plate 8 in the horizontal direction.

[0073] In this embodiment, the padlock baffle 7 is provided so that when the padlock plate 6 is in the padlocked state, manual operation by the user is restricted to prevent the risk of electric shock.

[0074] When the padlock plate 6 moves in the vertical direction, the linkage member 9 drives the padlock baffle 7 to slide in the horizontal direction.

[0075] The plastic liner 10 is provided with a rotating shaft 130 pivotally matched with the linkage member 9, and the linkage member 9 is rotatably arranged relative to the rotating shaft 130. In this embodiment, by arranging the linkage member 9, when the padlock plate 6 moves in the vertical direction, the padlock baffle 7 can be driven to move in the horizontal direction.

[0076] The padlock baffle 7 is penetrated with a stop hole 71 along the vertical direction. When the circuit breaker is closed, the padlock plate 6 is in a receiving state, and one end of the linkage member 9 is inserted into the stop hole 71 along the vertical direction.

[0077] The padlock baffle 7 is provided with a driving plate 72 protruding downward in the vertical direction. When the padlock plate 6 is switched from the receiving state to the padlock state, the linkage member 9 pushes the driving plate 72 in the horizontal direction to drive the padlock baffle 7 to move in the horizontal direction.

[0078] The padlock baffle 7 is provided with a limit shaft 73 protruding upward in the vertical direction, and the track groove 114 extends in the horizontal direction. The limit shaft 73 is inserted into the track groove 114 and is slidably arranged relative to the track groove 114 .

[0079] The padlock plate 6 is provided with a driving block 67 for abutting against the linkage member 9 in the vertical direction. When the padlock plate 6 moves upward, the driving block 67 can drive the linkage member 9 to rotate, so that the end of the linkage member 9 is disengaged from the stop hole 71 on the one hand, and the linkage member 9 pushes the driving plate 72 to drive the padlock baffle 7 to move in the horizontal direction on the other hand. When the padlock plate 6 moves downward, the upper end of the linkage member 9 is gradually inserted into the stop hole 71, and drives the padlock baffle 7 to move in the horizontal direction.

[0080] The padlock baffle 7 is located in the exposure slot 81 and abuts against the manual operation panel 8 in the horizontal direction.

[0081] The manual operation panel 8 is provided with a limiting step 83 protruding toward the exposure slot 81, and the padlock baffle 7 is mounted on the limiting step 83. The limiting step 83 plays the role of supporting the padlock baffle 7 on the one hand, and limiting the swing of the padlock baffle 7 on the other hand.

[0082] When the padlock plate 6 is in the retracted state, the user can freely move the manual operation plate 8 without driving the padlock baffle 7 to move, so that the manual operation plate 8 is blocked between the operation hole 112 and the operation panel 3, or the exposure slot 81 is located between the operation hole 112 and the operation panel 3. When the padlock plate 6 is in the padlocked state, the padlock baffle 7 pushes the manual operation plate 8 to move, and although the exposure slot 81 is located between the operation hole 112 and the operation panel 3, the padlock baffle 7 must be located in the exposure slot 81, thereby blocking the operation panel 3 and avoiding the danger caused by manual operation.

[0083] By providing the linkage member 9, the padlock plate 6 can drive the padlock baffle 7 to move, thereby avoiding the danger caused by manual operation during padlocking.

[0084] The control circuit board 5 is electrically connected to the connection component 4 to control the operation of the connection component 4. More specifically, the control circuit board 5 is provided with a switching power supply, a power conversion circuit, a sampling switch and circuit, and a control circuit.

[0085] The switch power supply is used to control the switch of the drive motor 41, and the power conversion circuit is used to adjust the output voltage. The sampling switch may include manual and automatic state sampling, opening and closing position sampling, reset signal sampling or trip signal sampling, etc. The control circuit can realize functions such as remote control.

[0086] like Figures 1 to 7 , Figure 15 to Figure 16As shown, the display hole 111 is vertically opposite to the operation panel 3. The operation panel 3 has at least two first display parts 32 exposed from the display hole 111.

[0087] The separation and combination indicating slide plate 101 is disposed between the operating panel 3 and the display cover 11 , and a second display portion 1011 and a through hole 1012 are provided on the separation and combination indicating slide plate 101 .

[0088] The driving assembly 102 is used to drive the separation and combination indicating slide plate 101 to slide, and the driving assembly 102 drives the separation and combination indicating slide plate 101 to move so that the second display portion 1011 or the through hole 1012 is located below the display hole 111. When the through hole 1012 is located below the display hole 111, the first display portion 32 is exposed from the display hole 111.

[0089] In this embodiment, the first display portion 32 is a different color block arranged on the side of the operating panel 3 facing the display cover 11 and is staggered along the circumferential direction. The second display portion 1011 is another color block arranged on the separation and combination indicating slide plate 101.

[0090] More specifically, the second display part 1011 is a red block, and the two first display parts 32 are green and white blocks respectively. The identification icon 115 corresponds to different colors, red for closing (ON), green for opening (OFF), and white for tripping (TRIPPED or TRIP). When closing, the second display part 1011 is located below the display hole 111, and the display hole 111 can only expose the red color on the second display part 1011. When opening, the display hole 111 exposes the green color on the first display part 32 through the through hole 1012. In this state, if there is a tripping problem, the operating panel 3 will rotate relatively, and the display hole 111 will expose the white color.

[0091] The driving assembly 102 includes an indicating push rod 1021 and an indicating rotating member 1022, and the indicating push rod 1021 and the indicating rotating member 1022 are both arranged on the side of the separation and combination indicating slide plate 101 away from the display cover 11, and the indicating push rod 1021 slides in a direction perpendicular to the separation and combination indicating slide plate 101, and the indicating rotating member 1022 is driven by the indicating push rod 1021 to drive the separation and combination indicating slide plate 101 to move in a horizontal direction, thereby making the second display part 1011 or the through hole 1012 located below the display hole 111.

[0092] The indicating rotating member 1022 and the plastic liner 10 are rotatably arranged.

[0093] The separation / combination indicating slide plate 101 is provided with a driving fastener 1015 protruding toward the indicating rotating member 1022 , and one end of the indicating rotating member 1022 is inserted into the driving fastener 1015 to drive the separation / combination indicating slide plate 101 to slide when the indicating rotating member 1022 rotates.

[0094] The padlock plate 6 is provided with a limiting hole 68, and the indicating rotating member 1022 is provided with a limiting protrusion 1024. When the circuit breaker is closed, the limiting protrusion 1024 is inserted into the limiting hole 68 to limit the padlock plate 6 from hanging. In this embodiment, in addition to the slider 44, the indicating rotating member 1022 linked with the opening and closing indicating slide plate 101 can also play a role in limiting the padlocking of the padlock plate 6.

[0095] The outer shell 1 is provided with a reset block 116 protruding toward the separation and closing indication slide 101. Specifically, the reset block 116 is arranged on the display cover 11. The separation and closing indication slide 101 is provided with a first reset spring 1013. When the circuit breaker is closed, the first reset spring 1013 is compressed. When the circuit breaker is opened, the first reset spring 1013 is reset to drive the separation and closing indication slide 101 to slide in the horizontal direction.

[0096] A receiving groove 1014 is formed on one side of the opening / closing indicating slide plate 101 facing the display cover 11 , and the first return spring 1013 is disposed in the receiving groove 1014 .

[0097] The indicating push rod 1021 is provided with a second return spring 1023 for abutting against the plastic pad 10. When the circuit breaker is closed, the second return spring 1023 is compressed. When the circuit breaker is opened, the second return spring 1023 is reset to drive the indicating push rod 1021 to slide in the horizontal direction.

[0098] like Figures 1 to 6 As shown, the working process of the electric operating device 100 of the present invention is as follows: when the electric operating device 100 needs to control the circuit breaker to close, it is necessary to ensure that the padlock plate 6 is in the receiving state, and the slider 44 is driven to slide manually or electrically to drive the switch handle 2 to rotate;

[0099] When the switch is closed, the slider 44 abuts against the abutting block 65, and the slider 44 abuts against the abutting block 65 to limit the padlock plate 6 from hanging. At the same time, the limiting protrusion 1024 of the indicating rotating member 1022 is also inserted into the limiting hole 68, further limiting the padlock plate 6 from hanging, which serves as a double insurance; at the same time, the second display part 1011 is located below the display hole 111, indicating that the switch is closed at this time; regardless of whether the electric operating device 100 is in the open state or the closed state, as long as the padlock plate 6 is not hung, the user can manually move the manual operating panel 8 to decide whether to manually control the operating panel 3;

[0100] When the gate is opened and the padlock plate 6 is not hung, the slider 44 slides relatively. At this time, in the vertical direction, the slider 44 gives way to the abutting block 65, and the indicating push rod 1021 moves upward, driving the indicating rotating member 1022 to rotate, thereby driving the opening and closing indicating slide plate 101 to slide, so that the through hole 1012 is located below the display hole 111, exposing the first display part 32, and at the same time, the limiting protrusion 1024 is separated from the limiting hole 68, and the padlock plate 6 is no longer limited. In this state, the padlock plate 6 can be hung;

[0101] When the switch is opened and the padlock plate 6 is hung, the abutting block 65 is lifted and rotated relatively to abut the slider 44 in the horizontal direction to prevent the switch from closing. At the same time, the driving block 67 moves upward, driving the linkage member 9 to rotate and drive the padlock baffle 7 to move above the operating panel 3 to block the key hole 31 to prevent manual operation by the user.

[0102] When the padlock is released, the padlock plate 6 returns to the receiving state under the action of the second return spring 1023, and the abutting block 65 returns to the first state under the action of the torsion spring 66, releasing the restriction on the slider 44, and the padlock baffle 7 moves away from between the operating hole 112 and the manual operating plate 8 in the horizontal direction;

[0103] When the switch is switched from open to closed, the slider 44 moves to above the abutment block 65 , and the first return spring 1013 pushes the open / close indicating slide plate 101 to slide, driving the indicating rotating member 1022 to rotate and allowing the limiting protrusion 1024 to insert into the limiting hole 68 .

[0104] The electric operating device 100 of the present invention can indicate the opening, closing and tripping by providing the opening and closing indicating slide plate 101 and the driving assembly 102, and can cooperate with the padlock plate 6 to limit the padlock plate 6 when closing the switch; by providing the abutment block 65, the padlock plate 6 can be limited to be hung up by the slider 44 when closing the switch, and when the padlock plate 6 is hung, the movement of the slider 44 is limited to close the switch, thereby improving safety; by providing the padlock baffle 7, manual operation is limited when the padlock plate 6 is hung, thereby further improving safety. The electric operating device 100 of the present invention can realize electric automatic control and manual control, and has a compact structure, is easy to use and has high safety.

[0105] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
