The eight modules work together to realize the whole house intelligence.

[0054] Please refer to Figure 1 and Figure 2 The present application provides a transmission mechanism, which includes an electric component 10, a driving device, a contact mechanism 30 linked to the driving device, and a release member 40, wherein the release member 40 drives the driving device to disconnect the contact mechanism 30. The transmission mechanism can realize both electric and manual opening and closing, and has a simple structure, is easy to operate, and has good reliability.

[0055] It should be noted that, when the above transmission mechanism is applied to a circuit breaker, the two states of connection or disconnection of the contact mechanism 30 in the present application refer to the closed state or the open state of the contact mechanism 30 .

[0056] The drive device is linked with the contact mechanism 30, that is, the drive device and the contact mechanism 30 are in transmission connection, so that the movement of the drive device can drive the movement of the contact mechanism 30. It should be noted that the present application does not limit the specific linkage structure of the drive device and the contact mechanism 30, and those skilled in the art can set it as needed.

[0057] Furthermore, in this embodiment, the release member 40 can be linked with the driving device, so that the release member 40 can drive the driving device to move, so that the driving device drives the contact mechanism 30 to disconnect.

[0058] The present application does not limit the driving components of the above-mentioned release member 40, which can be driven by the electric component 10 or other components. In the following, the electric component 10 is mainly used as an example to drive the release member 40 to move.

[0059] In addition, it should be noted that the transmission mechanism provided in the present application can be applied to various types of switches, such as molded case circuit breakers, isolating switches, dual power switches, intelligent circuit breakers, leakage circuit breakers, small circuit breakers, etc., and the present application does not limit this.

[0060] In this embodiment, during electric closing, the electric assembly 10 can drive the driving device to move, so that the driving device drives the contact mechanism 30 to connect; during electric opening, the electric assembly 10 can drive the tripping member 40 to move, so that the tripping member 40 drives the driving device to move and thus realize electric opening; during manual opening and closing, the driving device can drive the contact mechanism 30 to move, so that the contact mechanism 30 is connected or disconnected. The transmission mechanism can realize opening and closing in both electric and manual modes, and its structure is simple, easy to operate, and has good reliability.

[0061] Optionally, the driving device includes at least one of the following:

[0062] First, at least one handle that drives the contact mechanism 30 to connect and / or disconnect.

[0063] When the driving device includes at least one handle, the handle may be completely or partially built into the housing 70 , or may be completely or partially protruded from the housing 70 .

[0064] Second, the first handle 20 and / or the second handle 60 drive the contact mechanism 30 to connect or disconnect.

[0065] The first handle 20 and the second handle 60 can refer to Figure 1 and Figure 2 As shown, in this embodiment, the switch can be opened and closed by driving the second handle 60. In this embodiment, the following mainly takes the example that the driving device includes the first handle 20 and the second handle 60 as an example for explanation.

[0066] The transmission relationship between the second handle 60 and the electric assembly 10 includes at least one of the following:

[0067] First, the electric component 10 is in transmission connection with the release member 40 , and the release member 40 is in transmission connection with the second handle 60 ; the electric component 10 drives the release member 40 to rotate, and the release member 40 drives the second handle 60 to rotate.

[0068] Second, the electric component 10 is in transmission connection with the first handle 20 , and the first handle 20 is in transmission connection with the second handle 60 ; the electric component 10 drives the first handle 20 to rotate, and the first handle 20 drives the second handle 60 to rotate.

[0069] That is to say, the transmission relationship between the first handle 20 and the electric assembly 10 can satisfy at least one of the first and second situations mentioned above.

[0070] In the first case, the electric assembly 10 drives the release member 40 to rotate, and the release member 40 can drive the second handle 60 to rotate, so that the second handle 60 can drive the contact mechanism 30 to disconnect through the first handle 20 .

[0071] In the second case mentioned above, the electric component 10 drives the first handle 20 to rotate, and the first handle 20 drives the second handle 60 to rotate (at this time, the first handle 20 can also drive the contact mechanism 30 to connect), and the second handle 60 can be in the connection position together with the contact mechanism 30.

[0072] Optionally, the position relationship of the second handle 60 includes at least one of the following:

[0073] First, the second handle 60 is located on the same side of the release member 40 and / or the first handle 20. That is, in this positional relationship, the second handle 60 is not between the release member 40 and the first handle 20.

[0074] Second, the second handle 60 and / or the electric assembly 10 are arranged along a first direction, and the first direction is arranged at an angle to the length direction of the housing 70 of the circuit breaker.

[0075] Third, the second handle 60 is located on the side of the release member 40 away from the electric assembly 10. That is, in this positional relationship, the second handle 60 is not between the release member 40 and the electric assembly 10.

[0076] Of course, the positional relationship of the second handle 60 can satisfy at least one or more of the above relationships.

[0077] Furthermore, in this embodiment, the positional relationship between the driving device and the housing 70 of the circuit breaker includes at least one of the following:

[0078] First, the driving device is partially or completely built into the housing 70. That is, the driving device is at least partially located in the housing 70.

[0079] Second, the driving device is partially or completely protruded outside the housing 70. That is, the driving device is at least partially located outside the housing 70.

[0080] The present application does not limit the specific position of the driving device, and those skilled in the art can select any of the above settings as needed.

[0081] For ease of understanding, the specific structures of the electric assembly 10, the driving device, the release member 40 and the contact mechanism 30 are described below by way of example.

[0082] The electric assembly 10, the first handle 20, the contact mechanism 30 and the release member 40 can all be disposed in the housing 70 of the circuit breaker. In this embodiment, the first handle 20 and the release member 40 can both be rotatably connected in the housing 70.

[0083] The electric component 10 is transmission-connected with the first handle 20, and the electric component 10 is used to drive the first handle 20 to rotate. Specifically, the structural form of the electric component 10 is not limited in this application, as long as it can drive the first handle 20 to rotate so that the first handle 20 drives the contact mechanism 30 to move, thereby realizing the connection of the contact mechanism 30.

[0084] The first handle 20 is located between the electric component 10 and the contact mechanism 30. In this embodiment, the first handle 20 is connected to the electric component 10 in a transmission manner, and is also connected to the contact mechanism 30 in a transmission manner.

[0085] The contact mechanism 30 is in transmission connection with the first handle 20, and can be disconnected or connected with the static contact of the circuit breaker under the drive of the first handle 20. The present application does not limit the specific structure of the contact mechanism 30, and those skilled in the art can select and design the structure of the contact mechanism 30 according to actual conditions.

[0086] The release member 40 is located between the first handle 20 and the electric assembly 10, and the release member 40 is rotatably connected to the housing 70. The release member 40 can be used to drive the first handle 20 to move, so that the first handle 20 drives the contact mechanism 30 to move, so that the contact mechanism 30 realizes electric opening.

[0087] In addition, the first handle 20 of the present application and the second handle 60 of the circuit breaker are transmission-connected, so that directly driving the second handle 60 to move can also drive the first handle 20 to rotate, thereby causing the first handle 20 to drive the contact mechanism 30 to disconnect or connect.

[0088] The second handle 60 and the first handle 20 may be connected via a first connecting rod 81, and the first handle 20 and the contact mechanism 30 may be connected via a second connecting rod 82. Figure 1 shown.

[0089] The working principle of the transmission mechanism provided in this application is as follows:

[0090] Electric closing: The electric assembly 10 drives the first handle 20 to rotate, and the first handle 20 drives the contact mechanism 30 to move, so that the contact mechanism 30 is connected, such as Figure 2 and Figure 3 ;

[0091] Electric opening: When the contact mechanism 30 is in the connected state (such as Figure 3As shown), at this time, the electric assembly 10 drives the release member 40 to rotate, and the release member 40 can drive the first handle 20 to rotate so that the contact mechanism 30 is disconnected;

[0092] Manual opening and closing: The second handle 60 is driven to move, so as to drive the first handle 20 to move, so that the first handle 20 drives the contact mechanism 30 to disconnect or connect. It should be noted that the second handle 60 can be as follows: Figure 1 In the rotating type shown, the second handle 60 can be driven to move by manually pressing the second handle 60.

[0093] The present application sets a release member 40 between the electric component 10 and the first handle 20, so that when the switch is electrically closed, the electric component 10 can drive the first handle 20 to rotate, so that the first handle 20 drives the contact mechanism 30 to connect; and when the connection is disconnected, the electric component 10 can drive the release member 40 to rotate, so that the release member 40 drives the first handle 20 to rotate and thus realize electric opening; and the first handle 20 is transmission-connected with the second handle 60, so that the first handle 20 can also be driven to move by driving the second handle 60 to move, so that the first handle 20 drives the contact mechanism 30 to disconnect or connect. In this way, the present application can realize electric opening and closing and manual opening and closing, and the overall structure of the transmission mechanism provided by the present application is also relatively simple. During electric operation, only the electric component 10 needs to be driven, and when the motor 11 is powered off or fails, the second handle 60 can still be driven by manual operation. It has strong operability and a relatively simple operation method. At the same time, since the structure of the present application is relatively simple compared to some implementations, it can also improve the working reliability of the mechanism and effectively solve the problem of poor structural reliability caused by wear during the transmission process.

[0094] Please refer to Figure 5 As shown, optionally, the release member 40 includes a main body 41 rotatably connected to the shell 70 and a first drive rod 42 and / or a second drive rod 43 respectively fixedly connected to the main body 41; when the contact mechanism 30 is in a connected state, the electric component 10 drives the first drive rod 42 to rotate, and the first drive rod 42 can drive the second drive rod 43 to rotate through the main body 41, so that the second drive rod 43 drives one end of the second handle 60 to rotate to drive the first handle 20 to rotate to disconnect the contact mechanism 30.

[0095] That is, the release member 40 includes a body 41, a first drive rod 42 and / or a second drive rod 43. The following mainly describes the release member 40 by taking the first drive rod 42 and the second drive rod 43 as an example. The first drive rod 42 and the second drive rod 43 are respectively connected to the body 41, and the orthographic projections of the first drive rod 42 and the second drive rod 43 on the housing 70 do not overlap. In this embodiment, the body 41 is rotatably connected to the housing 70, and the first drive rod 42, the second drive rod 43 and the body 41 can be an integrally formed part.

[0096] In this way, when the contact mechanism 30 is in a connected state, the electric component 10 can drive the first drive rod 42 to rotate, so that the first drive rod 42 drives the second drive rod 43 to rotate through the main body 41, so that the second drive rod 43 can drive the second handle 60 to rotate to drive the first handle 20 to rotate, thereby achieving the disconnection of the contact mechanism 30.

[0097] like Figure 4 As shown, optionally, in this embodiment, the above-mentioned electric component 10 also includes a lever 13, the lever 13 and the first sector tooth 121 of the electric component 10 are stacked, and one end of the lever 13 is fixedly connected to the rotation center of the first sector tooth 121 of the electric component 10, and the other end is used to push the first driving rod 42 to rotate.

[0098] In this way, when the switch is electrically closed, the first sector-shaped tooth 121 of the electric component 10 can drive the second sector-shaped tooth 21 of the first handle 20 to move, thereby driving the first handle 20; and when the switch is electrically opened, the electric component 10 continues to drive the first sector-shaped tooth 121 to rotate, while the lever 13 fixedly connected to the rotation center of the first sector-shaped tooth 121 will rotate synchronously. At this time, the lever 13 will push the first driving rod 42 to rotate, thereby causing the second driving rod 43 to drive the second handle 60 to rotate to drive the first handle 20 to rotate. Figure 3 and Figure 5 shown.

[0099] like Figure 1 As shown, the electric assembly 10 may include a motor 11 and / or a gear set 12 drivingly connected to the motor 11, the gear set 12 having a first sector tooth 121; the first handle 20 having a second sector tooth 21 for meshing with the first sector tooth 121. The lever 13 and the orthographic projection of the first sector tooth 121 on the housing 70 are arranged at intervals.

[0100] It should be noted that, first, the present application does not limit the structural form of the gear set 12, and the specific number of gears of the gear set 12 can be determined by those skilled in the art according to actual conditions. Figure 1 The structure of the gear set 12 is merely an example given in the present application and is not intended to be a limitation of the present application.

[0101] The gear set 12 has a first sector-shaped tooth 121, and the first handle 20 has a second sector-shaped tooth 21. The first sector-shaped tooth 121 can be engaged with or separated from the second sector-shaped tooth 21. Figures 1 to 3 When the transmission mechanism needs to be connected, the first sector teeth 121 and the second sector teeth 21 can mesh with each other, so that the gear set 12 and the first handle 20 are connected in transmission.

[0102] Second, in this embodiment, the orthographic projections of the lever 13 and the first sector tooth 121 on the housing 70 are arranged at intervals, such as Figure 3 and Figure 4 As shown, in this way, the first sector tooth 121 and the shifting rod 13 can move independently without causing motion interference.

[0103] In addition, in this embodiment, the housing 70 includes an upper housing and / or a lower housing that are interlocked, and the lever 13 is located on a side of the electric component 10 close to the lower housing. Figure 1 and Figure 3 shown.

[0104] Among them, the present application does not limit the specific buckling method of the upper shell and the lower shell, and technical personnel in this field can set it by themselves.

[0105] In addition, in this embodiment, a mounting post is protruded from the lower shell, and the release member 40 is rotatably connected to the mounting post.

[0106] like Figure 2 and Figure 3 As shown, specifically, the body 41 of the release member 40 is rotatably connected to the mounting post. In this embodiment, the body 41 has a central hole that matches the mounting post.

[0107] In addition, it should be noted that in this embodiment, please refer to Figure 6 The transmission mechanism may further include a return spring 50 sleeved on the body 41 , one end of the return spring 50 is connected to the second driving rod 43 , and / or the other end of the return spring 50 is fixed to the housing 70 .

[0108] The present application sets the reset spring 50, so that during the electric opening process, the reset spring 50 can store energy, and after the opening is completed, the reset spring 50 releases energy to drive the release member 40 to reset to prepare for the next electric opening. It should be noted that when the release member 40 is reset, the release member 40 will return to a state of being separated from the second handle 60 and the lever 13.

[0109] Alternatively, if Figure 2 and Figure 3As shown, an end of the second handle 60 close to the electric component 10 is provided with an action rod 90 protruding toward the release member 40; when the contact mechanism 30 is in a connected state, the electric component 10 drives the first drive rod 42 to rotate, and the first drive rod 42 can drive the second drive rod 43 to rotate through the main body 41, so that the second drive rod 43 drives one end of the second handle 60 to rotate through the action rod 90 to drive the first handle 20 to rotate.

[0110] That is, when the release member 40 drives the second handle 60 to move, it is specifically achieved by the second driving rod 43 of the release member 40 driving the action rod 90 of the second handle 60 to move.

[0111] In this embodiment, the second driving rod 43 has a bent portion, and the bent portion acts on the action rod 90. The present application increases the contact area between the release member 40 and the action rod 90 by providing the bent portion, thereby improving the driving reliability.

[0112] Optionally, a surface of the actuating rod 90 facing the bending portion and a surface of the bending portion facing the actuating rod 90 are parallel or approximately parallel.

[0113] It should be noted that if Figures 1 to 5 As shown, when the contact mechanism 30 is in the connected state, the lever 13 pushes the first driving rod 42 to rotate, and the second driving rod 43 can push one end of the second handle 60 to rotate to drive the first handle 20 to rotate so that the contact mechanism 30 is disconnected.

[0114] In this embodiment, when the lever 13 drives the first driving rod 42 to rotate, the second driving rod 43 drives the second handle 60 to rotate to drive the first handle 20 to rotate. That is, in this embodiment, the release member 40 indirectly drives the first handle 20 to rotate to achieve electric opening.

[0115] It should be noted that in this manner, a columnar member (i.e., the actuating rod 90 mentioned above) can be correspondingly provided at one end of the second handle 60 close to the release member 40, so that the second driving member of the release member 40 can drive the columnar member to rotate the second handle 60, thereby driving the first handle 20 to rotate.

[0116] In this embodiment, the electric opening and closing principle of the transmission mechanism is as follows:

[0117] Electric closing: The motor 11 drives the gear set 12 to rotate, the first sector teeth 121 of the gear set 12 drives the second sector teeth 21 of the first handle 20 to rotate, and the first handle 20 drives the contact mechanism 30 to move through the second connecting rod 82, so that the contact mechanism 30 is connected, such as Figure 2 and Figure 3 ;

[0118] Electric opening: When the contact mechanism 30 is in the connected state (such as Figure 3 As shown), at this time, the motor 11 drives the gear set 12 to rotate (the rotation direction is the same as the rotation direction when the switch is closed), and the lever 13 on the gear set 12 rotates synchronously. The lever 13 can push the first drive rod 42 of the release member 40 to rotate, so that the first drive rod 42 drives the second drive rod 43 to rotate at the same time through the body 41. At this time, the bent portion of the second drive rod 43 can move the action rod 90 of the second handle 60 to rotate the second handle 60. At this time, the second handle 60 drives the first handle 20 to rotate through the first connecting rod 81. In this way, the first handle 20 will drive the contact mechanism 30 to disconnect through the second connecting rod 82.

[0119] It should be noted that when the lever 13 drives the first driving rod 42 to rotate, the second driving rod 43 can drive the second handle 60 to indirectly drive the first handle 20 to rotate, or can directly drive the first handle 20 to rotate. The above-mentioned method of indirectly driving the first handle 20 to rotate by driving the second handle 60 is only an example given in the present application, and is not a limitation of the present application. Those skilled in the art can select a suitable method according to their needs.

[0120] For example, when the shifting rod 13 drives the first driving rod 42 to rotate, the second driving rod 43 can also directly drive the first handle 20 to rotate.

[0121] At this time, if Figures 7 to 10 Optionally, the release member 40 includes a body 41 rotatably connected to the shell 70 and a first drive rod 42 and / or a second drive rod 43 respectively fixedly connected to the body 41; the electric component 10 also includes a lever 13, the lever 13 and the first sector tooth 121 are stacked, and one end of the lever 13 is fixedly connected to the rotation center of the first sector tooth 121 of the electric component 10, and the other end is used to push the first drive rod 42 to rotate; a boss 22 is provided on the first handle 20; when the contact mechanism 30 is in a connected state, the lever 13 pushes the first drive rod 42 to rotate, and the second drive rod 43 can drive the first handle 20 to rotate by pushing the boss 22 to rotate, so that the contact mechanism 30 is disconnected.

[0122] Among them, this method is to provide a boss 22 on the first handle 20, so that when the contact mechanism 30 is in a connected state, the lever 13 pushes the first drive rod 42 to rotate, and the second drive rod 43 can drive the first handle 20 to rotate by pushing the boss 22 to rotate, so that the contact mechanism 30 is disconnected.

[0123] In this embodiment, when the lever 13 pushes the first driving rod 42 to rotate, the second driving rod 43 can directly act on the boss 22 on the first handle 20 (in this embodiment, the boss 22 and the first handle 20 can be an integrally formed part), so that the first handle 20 rotates to drive the contact mechanism 30 to disconnect. Figure 8 and Fig. 9 Compared with the above-mentioned method of indirectly driving the first handle 20 by driving the second handle 60 , this method has a simpler transmission method.

[0124] In this embodiment, the principle of electric opening and closing of the transmission mechanism is as follows:

[0125] Electric closing: The motor 11 drives the gear set 12 to rotate, the first sector teeth 121 of the gear set 12 drives the second sector teeth 21 of the first handle 20 to rotate, and the first handle 20 drives the contact mechanism 30 to move through the second connecting rod 82, so that the contact mechanism 30 is connected, such as Figure 7 and Figure 8 ;

[0126] Electric opening: When the contact mechanism 30 is in the connected state (such as Figure 8 As shown in FIG. 1 , at this time, the motor 11 drives the gear set 12 to rotate (the rotation direction is the same as the rotation direction when the switch is closed), and the lever 13 on the gear set 12 rotates synchronously. The lever 13 can push the first driving rod 42 of the release member 40 to rotate, so that the first driving rod 42 drives the second driving rod 43 to rotate simultaneously through the body 41. At this time, the second driving rod 43 drives the first handle 20 to rotate by shifting the protrusion 22 on the first handle 20 (as shown in FIG. 1 ). Fig. 9 As shown), the first handle 20 will drive the contact mechanism 30 to disconnect through the second connecting rod 82, as shown in FIG. Figure 7 shown.

[0127] Please refer to Figure 7 , Figure 8 and Fig.10 As shown, optionally, the transmission mechanism further includes a first limiting member 71 fixed on the shell 70 (specifically the lower shell), and the first limiting member 71 is located on a side of the second driving rod 43 away from the first driving rod 42 and is used to limit the second driving rod 43.

[0128] The provision of the first limiter 71 can limit the rotation angle of the release member 40 within a certain range, thereby preventing the first limiter 71 from deflecting before the gate is opened, resulting in the lever 13 being unable to act on the first driving rod 42 when the gate is opened.

[0129] It should be noted that the setting position of the first limiter 71 should be based on the fact that when the motor 11 drives the lever 13 to rotate through the gear set 12, the sweeping area of ​​the lever 13 can act on the first driving rod 42 of the release member 40.

[0130] Furthermore, it should be noted that the release member 40 should be able to enable the second drive rod 43 to act on the second handle 60 or the boss 22 when the lever 13 drives the first drive rod 42 .

[0131] Optionally, the transmission mechanism may also include a second limiting member 72 disposed on the shell 70 (specifically the upper shell), and the second limiting member 72 and the first limiting member 71 are spaced apart in their orthographic projections on the shell 70. The second limiting member 72 is located on the side of the second driving rod 43 away from the first driving rod 42 and is used to limit the second driving rod 43.

[0132] The setting position and setting requirements of the second limiting member 72 are the same as those of the first limiting member 71, and the present application will not repeat them here.

[0133] It should be noted that, in this embodiment, the shell 70 includes an upper shell and a lower shell that are interlocked, the first limit member 71 is arranged on the lower shell and extends toward the upper shell; and the second limit member 72 is arranged on the upper shell and extends toward the lower shell.

[0134] Furthermore, in this embodiment, the orthographic projections of the first limiting member 71 and the second limiting member 72 on the shell 70 (specifically, the upper shell or the lower shell) are arranged at intervals, so that the two limiting members can work together to improve the limiting reliability of the limiting members.
