[0031] The embodiment of the present utility model provides an intelligent circuit breaker, which can facilitate automatic opening of the intelligent circuit breaker, has a compact structure, and reduces development costs.

[0032] like Figure 1 As shown, the embodiment of the present invention provides an intelligent circuit breaker, which includes: a housing 100 and an air switch module 200, and the air switch module 200 is arranged in the housing 100. In this application, the air switch module 200 includes a traditional air circuit breaker with a single pole and a neutral line. Figure 2 As shown, the air switch module 200 includes a tripping mechanism 210 and an automatic tripping mechanism 220 for disconnecting the circuit, wherein the automatic tripping mechanism 220 includes a driving component 221 and a tripper 222, and the tripper 222 is installed on the air switch module 200. When the intelligent circuit breaker receives a tripping instruction and needs to trip, the driving component 221 drives the tripper 222 to move, and the tripper 222 can push the tripping mechanism 210 to disconnect the circuit.

[0033] The technical solution of the present invention is to build an automatic tripping mechanism 220 into the air switch module 200. The automatic tripping mechanism 220 includes a driving component 221 and a tripper 222. The driving component 221 can drive the tripper 222 to move. When the intelligent circuit breaker receives a tripping instruction and needs to trip, the driving component 221 drives the tripper 222 to move. The tripper 222 can push the tripping mechanism 210 to disconnect the circuit. By building the automatic tripping mechanism 220 into the air switch module 200, it is beneficial to simplify the structure of the intelligent circuit breaker. The intelligent circuit breaker can automatically trip when an abnormality occurs in the circuit. The automatic tripping function of the intelligent circuit breaker is realized through modular design, which improves the efficiency and convenience of use and reduces the development cost.

[0034] like Figure 2 As shown, the tripper 222 includes a tripping end 2221 , which abuts against the push block 2213 . When tripping is required, the driving assembly 221 can push the tripping end 2221 , and the tripper 222 drives the tripping mechanism 210 to achieve tripping.

[0035] like Figure 3 As shown, the driving assembly 221 includes: a driving member 2211, a rotating wheel 2212 and a pushing block 2213. The driving member 2211 includes a rotating output shaft S1, which is rotatably connected to the rotating wheel 2212 and can drive the rotating wheel 2212 to rotate. One side of the pushing block 2213 abuts against the rotating wheel 2212, and the other side abuts against the release 222. The rotation of the rotating wheel 2212 can drive the pushing block 2213 to reciprocate, so that the pushing block 2213 can drive the release 222 to move, so as to push the tripping mechanism 210 to disconnect the circuit.

[0036] In this embodiment, the driving member 2211 comprises a reduction motor, and the diameter of the reduction motor's rotary output shaft S1 is 10 mm. The rotating wheel 2212 comprises a cam, the dimensions of which match the diameter of the rotary output shaft S1. In other embodiments, those skilled in the art may also determine the form and dimensions of the driving member 2211 based on actual needs to ensure a better matching connection between the driving member 2211 and the rotating wheel 2212.

[0037] like Figure 3 As shown, the rotating wheel 2212 includes a wheel body S2 and a protruding column S3, and the protruding column S3 is protrudingly arranged on the surface of the wheel body S2. Figure 5 As shown, the push block 2213 has a first slot S4 on one side near the rotating wheel 2212. The protruding post S3 is movable within the first slot S4 and abuts against the inner wall of the first slot S4, allowing the rotating wheel 2212 to drive the push block 2213 for reciprocating motion. The rotating wheel 2212 also includes a groove S8, the inner wall of which matches the shape of the rotating output shaft S1. The rotating output shaft S1 can extend into the groove S8, allowing the driving member 2211 to drive the rotating wheel 2212 to rotate.

[0038] like Figure 3 As shown, the push block 2213 also includes a protrusion S6, as shown in FIG. Figure 3 As shown, the protrusion S6 and the first sliding groove S4 are located on opposite sides of the pushing block 2213. Figure 2 As shown, the air switch module 200 further includes a mounting partition 230. Figure 4 As shown, the mounting partition 230 includes a second sliding groove 231 , the protrusion S6 can reciprocate along the second sliding groove 231 , and the second sensing element 232 is disposed in the second sliding groove 231 .

[0039] like Figure 2 As shown, the automatic tripping mechanism 220 is mounted on the mounting partition 230 , and the automatic tripping mechanism 220 and the tripping mechanism 210 are located on the same side of the mounting partition 230 , so that the tripper 222 can push the tripping mechanism 210 to disconnect the circuit.

[0040] like Figure 3 As shown, the push block 2213 also includes a first sensing member S5, such as Figure 4 As shown, a second sensing member 232 is further provided on the mounting partition 230 . When the second sensing member 232 senses the first sensing member S5 , the driving member 2211 stops driving the rotating wheel 2212 to rotate, and the rotating wheel 2212 stops driving the pushing block 2213 to move.

[0041] like Figure 2 As shown, the intelligent circuit breaker further includes a control module 300, which is electrically connected to the second sensing element 232. When the second sensing element 232 senses the first sensing element S5, the control module 300 controls the driving element 2211 to stop driving the rotating wheel 2212, and the rotating wheel 2212 to stop driving the pushing block 2213. In this embodiment, the control module 300 includes a main control board, which is disposed within the housing 100 and electrically connected to the automatic tripping mechanism 220.

[0042] In this embodiment, the first sensing element S5 and the second sensing element 232 include electromagnetic induction elements, the first sensing element S5 includes an induction magnet, and the second sensing element 232 includes a Hall plate. Induction is achieved between the induction magnet and the Hall plate through the Hall effect. When the Hall plate detects the induction magnet, the control module 300 controls the driving element 2211 to stop moving, so that the pushing block 2213 returns to its initial position.

[0043] like Figures 2 to 3 As shown, the protrusion S6 includes a mounting hole S7, and the first sensing element S5 is disposed in the mounting hole S7. Figure 4 As shown, the second sensing element 232 is disposed on the mounting partition 230 . When the protrusion S6 reciprocates along the second sliding groove 231 , the second sensing element 232 can sense the first sensing element S5 .

[0044] In this embodiment, the intelligent circuit breaker further includes a display module, which is electrically connected to the control module 300 and can display the working status of the intelligent circuit breaker.

[0045] Next, the working steps of the intelligent circuit breaker are described.

[0046] When an abnormality occurs in the circuit, the control module 300 controls the driving member 2211 to be energized, and the rotating output shaft S1 of the driving member 2211 drives the rotating wheel 2212 to rotate. The protruding column S3 of the rotating wheel 2212 can move in the first slide groove S4 of the pushing block 2213 and abut against the inner wall of the first slide groove S4, so that the rotating wheel 2212 can drive the pushing block 2213 to move, and the protruding part S6 of the pushing block 2213 can make a linear motion in the second slide groove 231 and push the releaser 222, so that the tripping end 2221 of the tripper 222 can push the tripping mechanism 210 to achieve tripping.

[0047] When the second sensing element 232 of the automatic opening mechanism 220 senses the first sensing element S5 provided on the pushing block 2213, the second sensing element 232 sends a signal to the control module 300 indicating that the pushing block 2213 is in place. The control module 300 controls the driving element 2211 to stop driving the rotating wheel 2212 to rotate, and the rotating wheel 2212 stops driving the pushing block 2213 to move.

[0048] This application helps to simplify the structure of the intelligent circuit breaker by integrating the automatic tripping mechanism 220 into the air switch module 200. The intelligent circuit breaker can automatically trip when an abnormality occurs in the circuit. The automatic tripping function of the intelligent circuit breaker is realized through modular design, which improves the efficiency and convenience of use and reduces the development cost.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
