For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Driven by intelligent and automated high-tech, the smart home industry has entered a period of rapid development. The smart home industry is facing new challenges and opportunities in the transformation of technology, market and industry.

[0037] According to the function, the smart home can be divided into eight modules: entertainment system, security system, control system, lighting system, kitchen and bathroom appliance system, network and communication system, health care system, and indoor environment system. The eight modules work together to realize the whole house intelligence.

[0038] Please refer to Figure 1 The present embodiment provides an operating mechanism including a contact base 10, a locking assembly 20 and a moving contact 30; the locking assembly 20 and the moving contact 30 are both connected to the contact base 10; when the locking assembly 20 is actuated, the moving contact 30 is driven to open or close the switch through the contact base 10. The operating mechanism has a simple structure and is easy to assemble.

[0039] It should be noted that the operating mechanism provided by the present application includes a contact base 10, a locking assembly 20 and a moving contact 30. The locking assembly 20 and the moving contact 30 are both mounted on the contact base 10. Thus, compared with mounting the locking assembly 20 on one component and mounting the moving contact 30 on another component, the arrangement of the present application can save at least one component, making the structure of the operating mechanism simpler.

[0040] The operating mechanism provided in the present application can be applied to a circuit breaker, or can also be applied to any other feasible mechanism, and the present application does not limit the application scenario of the operating mechanism. For ease of understanding and description, the following mainly uses the operating mechanism applied to a circuit breaker for example.

[0041] The contact base 10 is mounted on the housing 200 of the circuit breaker, and the contact base 10 is movably and rotatably connected to the housing 200. In this way, the driven movement of the contact base 10 on the housing 200 can drive the moving contact 30 mounted on the contact base 10 to move. In this way, the moving contact 30 can close or open the circuit breaker with the static contact 400 of the circuit breaker.

[0042] The locking assembly 20 has two states, namely a locked state (i.e., locked position) and an unlocked state (i.e., unlocked position). When the locking assembly 20 is in the locked position, the locking assembly 20 can be regarded as one component, and when the locking assembly 20 is in the unlocked position, the locking assembly 20 can be regarded as two components.

[0043] When the locking assembly 20 is in the locking position, the locking assembly 20 is in a locked state and will not move relative to the contact base 10. At this time, if the locking assembly 20 is driven to move, the locking assembly 20 will simultaneously drive the contact base 10 to move, and the contact base 10 will in turn drive the moving contact 30 connected thereto to move, so that the moving contact 30 can be opened or closed.

[0044] In summary, the operating mechanism provided by the present application includes a contact seat 10, a locking assembly 20 and a moving contact 30; the locking assembly 20 and the moving contact 30 are both connected to the contact seat 10; when the locking assembly 20 is actuated, the moving contact 30 is driven to open or close the switch through the contact seat 10. The present application installs both the moving contact 30 and the locking assembly 20 on the contact seat 10. Thus, compared with installing the locking assembly 20 on one component and installing the moving contact 30 on another component, the arrangement of the present application can save at least one component, thereby simplifying the structure of the operating mechanism and reducing the size of the operating mechanism; at the same time, since the present application can save at least one component, the assembly method of the operating mechanism can be simpler during assembly, which can reduce assembly errors and thus improve the working reliability of the operating mechanism.

[0045] In this embodiment, the moving contact 30 is movably connected to the contact base 10. In this way, when the contact base 10 drives the moving contact 30 to move so that the moving contact 30 and the static contact 400 are closed, the moving contact 30 can adjust the pre-pressure between the moving contact 30 and the static contact 400 through the driven movement, thereby ensuring that there is a certain contact pressure between the moving contact 30 and the static contact 400, so that there is a certain gap compensation between the moving contact 30 and the static contact 400.

[0046] Exemplarily, the gap compensation between the moving contact 30 and the stationary contact 400 can be achieved in the following manner: the operating mechanism can also include an elastic member, one end of the elastic member is connected to the contact seat 10, and the other end is connected to the moving contact 30, and the elastic member is used to adjust the pressure between the moving contact 30 and the stationary contact 400 of the circuit breaker.

[0047] That is to say, by providing the elastic member, a certain pre-pressure can be formed between the moving contact 30 and the stationary contact 400 through the elastic member, so that a certain gap compensation is provided between the moving contact 30 and the stationary contact 400 .

[0048] It should be noted that in order to facilitate replacement of the moving contact 30 when it is damaged and avoid the entire operating mechanism being scrapped due to damage to the moving contact 30, in this embodiment, the moving contact 30 can be installed on the contact seat 10 in a detachable connection manner.

[0049] For example, the contact seat 10 is provided with a third mounting shaft 14 , and the moving contact 30 is sleeved on the third mounting shaft 14 ; and the elastic member is sleeved on the third mounting shaft 14 .

[0050] Optionally, the contact seat 10 may include a first body 11 , and the third installation shaft 14 may be disposed on the first body 11 .

[0051] The elastic member may be a contact torsion spring 40. When the elastic member is a contact torsion spring 40, the third mounting shaft 14 is used to mount the movable contact 30 and the contact torsion spring 40. The movable contact 30 is mounted via the third mounting shaft 14, so that, firstly, the movable contact 30 is easily assembled on the contact seat 10; secondly, the movable contact 30 is easily replaced.

[0052] The present application does not limit the connection method and specific structure of the contact torsion spring 40, as long as the contact torsion spring 40 can adjust the pressure of the moving contact 30, so as to ensure sufficient contact pressure when closing the switch. In this way, in the closed state, a certain pre-pressure can be formed between the moving contact 30 and the stationary contact 400 through the contact torsion spring 40, so that there is a certain gap compensation effect between the moving contact 30 and the stationary contact 400.

[0053] Please refer to Figure 2 , Figure 3 and Figure 5 As shown, optionally, the contact seat 10 is further provided with a clamping portion 15 (the clamping portion 15 can be provided on the first body 11 ), one end of the elastic member is limited by the clamping portion 15 , and the other end of the elastic member is connected to the moving contact 30 .

[0054] It should be noted that when the elastic member is a contact torsion spring 40, the above-mentioned clamping portion 15 is provided on the contact seat 10, and the clamping portion 15 is used to limit one end of the contact torsion spring 40, and the other end of the contact torsion spring 40 is bent in a U shape to form a U-shaped bending portion 41 (please refer to Figure 2 and Figure 5 ), the open end of the U-shaped bending portion 41 faces the moving contact 30, and the U-shaped bending portion 41 is clamped on the outer wall of the moving contact 30, so that the moving contact 30 is connected to the contact seat 10 through the contact torsion spring 40, and the contact torsion spring 40 can adjust the pressure of the moving contact 30, so as to ensure sufficient contact pressure. In this way, in the closed state, a certain pre-pressure is formed between the moving contact 30 and the stationary contact 400 through the contact torsion spring 40, so that there is a certain gap compensation between the moving contact 30 and the stationary contact 400.

[0055] Please refer to Figures 2 to 4 Optionally, the above-mentioned clamping portion 15 includes a second body 151 having a clamping groove 1511 and a limit block 152 connected to the second body 151; the limit block 152 is located at the notch of the clamping groove 1511, and is used to limit the elastic member from escaping from the clamping groove 1511.

[0056] It should be noted that the above-mentioned limit block 152 is connected to the notch of the clamping slot 1511. Figure 4 The limiting block 152 is used to block a part of the slot opening of the clamping slot 1511 , so that the contact torsion spring 40 is limited in the clamping slot 1511 and will not easily fall out of the clamping slot 1511 .

[0057] Please refer to Figure 7 and Figure 8 Optionally, the operating mechanism further includes a reset spring 50 acting on the contact seat 10; the reset spring 50 can release energy when the operating mechanism is opened to drive the contact seat 10 to rotate.

[0058] It should be noted that one end of the reset spring 50 is relatively fixed, and the other end is used to act on the contact base 10 (it can be fixed or not fixed relative to the contact base 10). During the closing process of the operating mechanism, the contact base 10 squeezes the reset spring 50 to store energy in the reset spring 50; during the opening process of the operating mechanism, the reset spring 50 releases energy to drive the contact base 10 to move, which can make the operating mechanism open quickly and improve the breaking speed of the operating mechanism.

[0059] Optionally, a mounting groove 111 is recessed on the first body 11 of the contact holder 10 , and one end of the return spring 50 is clamped in the mounting groove 111 , and the other end is fixed relative to the housing 200 .

[0060] like Figure 8 As shown, the housing 200 may be provided with a limit groove 210, and one end of the return spring 50 away from the contact seat 10 may be clamped in the limit groove 210. In this way, one end of the return spring 50 is clamped in the limit groove 210 on the housing 200, and the other end is clamped in the mounting groove 111 on the contact seat 10.

[0061] Optionally, please refer to Figure 1 and Figure 2 The locking assembly 20 includes a lock buckle 21 and a jump buckle 22; the lock buckle 21 has a locking portion, and the jump buckle 22 has a matching portion. When the locking portion and the matching portion are engaged, the locking assembly 20 is in a locked position; when the locking portion and the matching portion are disengaged, the locking assembly 20 is in an unlocked position.

[0062] It should be noted that, in this embodiment, the lock buckle 21 is rotatably connected to the contact base 10, and the jump buckle 22 is rotatably connected to the contact base 10. The rotation center of the lock buckle 21 is located between the rotation center of the jump buckle 22 and the moving contact 30.

[0063] In addition, optionally, the line connecting the rotation center of the contact seat 10 and the rotation center of the lock buckle 21 is located between the rotation center of the moving contact 30 and the rotation center of the jump buckle 22, such as Figure 1 and Figure 4 shown.

[0064] In addition, the specific structure of the locking part on the lock buckle 21 and the matching part on the jump buckle 22 is not limited in this application, as long as the two can be locked or unlocked with each other so that the locking assembly 20 is in the locked position and the unlocked position.

[0065] Optionally, the lock catch 21 is rotatably connected to the contact base 10 , the moving contact 30 is movably connected to the contact base 10 , and the contact base 10 is rotatably connected to the housing 200 of the circuit breaker.

[0066] In this embodiment, if Figure 3 As shown, optionally, the contact seat 10 also includes a first installation shaft 12 provided on the first body 11 and a second installation shaft 13 provided on the first body 11 ; the first installation shaft 12 is used to install the jump buckle 22 , and the second installation shaft 13 is used to install the lock buckle 21 .

[0067] The present application sets a first mounting shaft 12 and a second mounting shaft 13, so that the jump buckle 22 can be sleeved on the first mounting shaft 12, and the lock buckle 21 can be sleeved on the second mounting shaft 13. In this way, when the jump buckle 22 and the lock buckle 21 are assembled on the contact seat 10, the assembly is convenient and the assembly error can be effectively avoided.

[0068] In addition, the clamping portion 15 mentioned above can be located between the rotation center of the moving contact 30 and the rotation center of the contact seat 10, such as Figure 3 shown.

[0069] The first installation axis 12 and the second installation axis 13 may be located on the same side of the rotation center of the contact base 10 ; the rotation centers of the first installation axis 12 , the second installation axis 13 and the contact base 10 are located on the same side of the clamping portion 15 .

[0070] The rotation centers of the first installation shaft 12 , the second installation shaft 13 and the contact base 10 are located on one side of the clamping portion 15 , and the moving contact 30 is located on the other side of the clamping portion 15 .

[0071] Please refer to Figure 1 and Figure 6 As shown, optionally, a first push portion 211 is provided at one end of the lock catch 21 close to the moving contact 30; the releaser 300 of the circuit breaker drives the first push portion 211 to move so that the lock catch 21 rotates relative to the contact seat 10, and the lock catch 21 and the trip catch 22 are unlocked.

[0072] The first push portion 211 is arranged toward one side of the static contact 400 of the circuit breaker, that is, the direction of the first push portion 211 is the same as the contact direction of the moving contact 30. In this way, when the tripper 300 of the circuit breaker receives an electrical signal, the top rod of the tripper 300 moves toward the moving contact 30, and the top rod of the tripper 300 can act on the first push portion 211 of the lock catch 21, so that the lock catch 21 rotates relative to the contact seat 10, so that the lock catch 21 and the trip catch 22 are unlocked. At this time, the contact seat 10 rotates under the energy release of the reset spring 50, thereby driving the moving contact 30 to rotate, so that the moving contact 30 and the static contact 400 are disconnected.

[0073] Please refer to Figure 6 Optionally, a second push portion 112 is provided on one side of the first body 11 close to the release 300, and the release 300 acts on the second push portion 112 to rotate the contact holder 10 relative to the housing 200 of the circuit breaker; the distance from the first push portion 211 to the release 300 is smaller than the distance from the second push portion 112 to the release 300.

[0074] The present application sets two push parts (i.e., the first push part 211 and the second push part 112), and makes the distance from the first push part 211 to the release 300 smaller than the distance from the second push part 112 to the release 300. In this way, when the release 300 receives an electrical signal, its push rod can first act on the first push part 211, so that the lock 21 rotates relative to the contact seat 10 to unlock the lock 21 and the tripping catch 22. At this time, the push rod of the release 300 acts on the second push part 112 again, so that the push rod can drive the contact seat 10 to rotate. At this time, the contact seat 10 rotates relative to the housing 200 under the driving action of the push rod and the energy release action of the reset spring 50, and can drive the moving contact 30 and the static contact 400 to open. Due to the setting of the second push part 112, the opening speed can be further improved.

[0075] In addition, if Figure 1 As shown, optionally, the operating mechanism may further include a handle 60 and a connecting rod 70, wherein the connecting rod 70 is connected between the handle 60 and the locking assembly 20. Exemplarily, one end of the connecting rod 70 away from the handle 60 may be connected to the trip buckle 22 of the locking assembly 20.

[0076] In addition, it should be noted that the moving contact 30 mentioned above may include two moving contacts 30, the two moving contacts 30 are respectively connected to the contact base 10, and the two moving contacts 30 are respectively located on opposite sides of the contact base 10, such as Figure 2 shown.

[0077] When there are two moving contacts 30, correspondingly, there are also two stationary contacts 400. When the moving contacts 30 of the operating mechanism are opened or closed with the stationary contacts 400, the two moving contacts 30 are opened or closed with the two stationary contacts 400 at the same time.
