These are structures and technologies well known to those skilled in the art. The present invention will not elaborate on the contents that have been fully disclosed in this part, and will not affect the understanding of the present invention by those skilled in the art.

[0029] like Figure 1-2 shown.

[0030] An intelligent control module, comprising:

[0031] The control panel 11 is used to collect circuit data in the circuit breaker and convert circuit analog signals into digital signal outputs, as well as receive control instructions and control various components to perform actions.

[0032] The data transmission module 12 is installed on the control board 11 and is used for outputting data of the control board 11 and inputting command data of the control board 11 .

[0033] The electric control component 13 is electrically connected to the control board 11 and is used to perform actions according to the instructions of the control board 11. It includes a motor component 131 connected to the control board 11, and a motor shaft (not marked) extends from one end of the motor component 131 for providing driving power according to the instructions of the control board 11.

[0034] like Figure 3 shown.

[0035] The gear assembly 132 cooperates with the motor assembly 131 to transmit the motor power and convert the power direction, including: a bevel gear 1321, which is interference fit with the motor assembly 131; a stepped boss 1322, including a small head 13221 and a large head 13224, the small head 13221 is provided with a through hole 13222, the small head 13221 axially extends a fan-shaped platform 13223, the fan-shaped platform 13223 is used to trigger the initial position detection switch 15, the large head 13224 is on the A fan ring gear portion 13225 is provided, and the fan ring gear portion 13225 is meshed with the bevel gear 1321 to transmit the power of the motor assembly 131. A fan ring blocking area 13226 is provided inside the large head 13224. The fan ring blocking area 13226 includes a first blocking area 13227 and a second blocking area 13228. The diameter of the second blocking area 13228 is larger than that of the first blocking area 13227. The second blocking area 13228 is used to restrict the range of motion of the shaft assembly 133.

[0036] like Figure 4 shown.

[0037] The shaft assembly 133, one end of which cooperates with the gear assembly 132, is used to transmit the motor power to rotate the handle to open and close, including an upper shaft assembly 1331, a lower shaft assembly 1332, and a special-shaped handle shaft 1333. The lower shaft assembly 1332 passes through the stepped boss 1322 and is connected to the upper shaft assembly 1331 through the special-shaped handle shaft 1333. The upper shaft assembly 1331 radially extends an upper extension boss 13311, and the upper extension boss 13311 is used to trigger the separation position detection assembly 14. The bottom of the upper shaft assembly 1331 is provided with a special-shaped countersunk hole 13312. The lower shaft assembly 1332 includes a connecting shaft 13 321, an annular portion 13322, a special-shaped through hole 13324 is provided in the connecting shaft 13321, the annular portion 13322 is arranged at the bottom of the connecting shaft 13321, the annular portion 13322 radially extends a lower extended boss 13323, the movable area of ​​the annular portion 13323 is in the fan ring baffle area 13226, the movable area of ​​the lower extended boss 13323 is in the second baffle area 13228, one end of the special-shaped handle shaft 1333 passes through the special-shaped through hole 13324, and after the transition fit of the special-shaped through hole 13324, it is interference fit with the special-shaped countersunk hole 13312.

[0038] The opening and closing position detection component 14 is used to detect the position of the shaft component 133 to reflect the opening and closing state of the circuit breaker, including an opening position detection switch 141 for detecting the opening position of the circuit breaker, and a closing position detection switch 142 for detecting the closing position of the circuit breaker.

[0039] The initial position detection switch 15 is used to detect the initial position of the gear assembly 132 .

[0040] The mounting plate 16 is used to limit the installation and movable positions of various components and to provide a mounting base for various components.

[0041] During the closing operation, the command issued by the user is transmitted to the control board 11 through the data transmission module 12, and the control board 11 controls the motor assembly 131 to work. The rotation of the motor assembly 131 drives the bevel gear 1321 to rotate, and the bevel gear 1321 drives the fan ring gear part 13225 on the stepped boss 1322 to rotate. During the rotation of the fan ring gear part, the second blocking area 13228 in the fan ring blocking area 13226 contacts the lower extension boss 13323 and pushes the lower extension boss 13323 to rotate. The rotation of the lower extension boss 13323 drives the shaft assembly 133 to rotate, and the rotation of the special-shaped handle shaft 1333 drives the circuit breaker handle connected thereto to rotate. When the upper extension boss 13311 triggers the closing position After the detection switch 142 is set, the circuit breaker completes closing, and the closing position detection switch 142 feeds back the closing signal to the control board 11, and the control board 11 feeds back the closing signal to the user through the data transmission module 12. At the same time, the control board 11 controls the motor assembly 131 to reverse, and the rotation of the motor assembly 131 drives the bevel gear 1321 to rotate, and the bevel gear 1321 drives the fan ring gear part 13225 on the stepped boss 1322 to rotate, until the fan-shaped platform 13223 is used to trigger the initial position detection switch 15, the initial position detection switch 15 feeds back the signal to the control board 11, and the control board 11 controls the motor assembly 131 to stop rotating, and at this time the gear assembly 132 returns to the initial position.

[0042] During the opening operation, the movement direction of the motor assembly 131 is opposite to the movement direction during the closing operation.

[0043] It should be noted that the second blocking area 13228 in the fan ring blocking area 13226 provides a range of movement for the lower extension boss 13323, that is, the second blocking area 13228 does not contact the lower extension boss 13323 within a certain separation range during the rotation process, and will not transmit the power of the motor assembly 131 to the lower extension boss 13323 within this separation range. Similarly, the lower extension boss 13323 will not be interfered by the second blocking area 13228 when rotating within this range. This range provides space for manual closing. That is, when the user closes the circuit breaker through the circuit breaker handle, the special-shaped handle shaft 1333 rotates to drive the shaft assembly 133 to rotate, and the lower extension boss 13323 rotates in the second blocking area 13228, and no power transmission occurs to the second blocking area 13228. The position of the gear assembly 132 does not change during manual closing, that is, this scheme achieves the compatibility of manual closing and automatic closing.

[0044] like Figure 5 shown.

[0045] In a specific embodiment, an intelligent control module is an independent accessory installed in an independent housing. One end of the special-shaped handle shaft 1333 passes through the housing and can be connected to the circuit breaker.

[0046] like Figure 6 shown.

[0047] In another specific embodiment, an intelligent control module is an independent accessory installed in an independent housing. To ensure that the intelligent control module has a greater power output, the gear assembly 132 in this embodiment adopts a multi-stage reduction gear set structure to ensure that the power transmission speed will not be too fast when the large-torque motor assembly 131 has a large power output. The multi-stage reduction gear set is a common gear power transmission assembly. People in this field can make adaptive modifications based on actual needs, which will not be described in detail in this embodiment.

[0048] like Figure 7-8 shown.

[0049] An intelligent circuit breaker includes at least a handle 21, a housing and a conventional circuit breaker component 2, characterized in that it also includes any of the above-mentioned intelligent control modules 1, and the handle 21 is provided with a handle-shaped through hole 211, the intelligent control module 1 is connected to the handle-shaped through hole 211, and is used for intelligently controlling the circuit breaker. The intelligent control module 1 is installed in the housing 2 of the intelligent circuit breaker.

[0050] It should be noted that the intelligent control module 1 is arranged in the circuit breaker 2 so that one circuit breaker has both manual and automatic closing functions. At the same time, it is conducive to more fully utilizing the internal space of the shell of the circuit breaker 2 and making the volume of the intelligent circuit breaker smaller. In this solution, the minimum width of the intelligent circuit breaker can reach 27 mm.

[0051] In a specific implementation, the intelligent control module 1 is installed in an independent housing and connected to the handle shaped through hole 211 on the handle 21 on the circuit breaker 2 as an independent accessory, so that a conventional circuit breaker 2 has the intelligent function of automatic closing without affecting manual closing. A further advantage of this solution is that it also realizes the isolation of the strong current in the circuit breaker 2 and the weak current in the intelligent control module 1. The arc generated during the disconnection process of the circuit breaker 2 will not affect the intelligent control module 1. At the same time, if the circuit breaker 2 fails, the data such as the opening and closing status of the circuit breaker can still be fed back to the user through the intelligent control module 1.

[0052] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
