[0034] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.
[0035] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc. may refer to different or the same objects.
[0036] As mentioned above, in conventional electric operating mechanisms, the motor and gear set rotate in one direction. Due to the limitations of torque and gear size, a multi-stage gear set needs to be set between the motor and the sliding assembly, resulting in a slower opening and closing speed, thereby reducing the response speed and stability of the system.
[0037] The embodiment of the present disclosure provides an electric operating mechanism 100 and a power switch. A sliding member 30, a delay assembly 20, a first micro switch 51 and a second micro switch 52 are provided in the electric operating mechanism 100. The movement of the sliding member 30 can be transmitted to the first micro switch 51 and the second micro switch 52 through the delay assembly 20, thereby adjusting the power supply direction of the electric assembly 40 at the closing position and the opening position. In this way, the electric operating mechanism 100 adjusts the opening and closing of the power switch by reciprocating motion, thereby improving the opening and closing speed, thereby improving the response speed and stability of the power switch. Figures 1 to 9 To describe the principles of the present disclosure in detail.
[0038] like Figure 1 and Figure 2 As shown, the electric operating mechanism 100 includes a base 10 , a delay assembly 20 , a sliding member 30 , an electric assembly 40 , a first micro switch 51 and a second micro switch 52 .
[0039] like Figure 1 and Figure 2As shown, the base 10 is the supporting structure of the electric operating mechanism 100, which is used to maintain the positional relationship between the delay component 20, the sliding member 30, the electric component 40, the first micro switch 51 and the second micro switch 52. The remaining components are mounted on the base 10 to maintain their relative positions stable, thereby ensuring that they do not deviate from their positions during operation.
[0040] As an example, metal pieces of different shapes and sizes can be selected as needed, and they can be assembled into the base 10 by welding, bolting, etc. In this way, the assembled base 10 can withstand a large load and maintain good stability and durability.
[0041] As another example, the metal material can be formed into the required base 10 through stamping, bending and other processes. In this way, material waste can be reduced, thereby achieving standardized and modular manufacturing, and facilitating subsequent assembly and maintenance.
[0042] like Figure 2 and Figure 3 As shown, the delay component 20 is rotatably mounted on the base 10. A protrusion 211 is provided on the delay component 20, and the protrusion 211 is used to cooperate with the first micro switch 51 and the second micro switch 52 to adjust the connection relationship of the circuit. The delay component 20 has the function of delaying action. For example, when the sliding member 30 acts on the delay component 20, the delay component 20 will not immediately transfer the action to the first micro switch 51 and the second micro switch 52, but will transfer the action to the first micro switch 51 and the second micro switch 52 when the sliding member 30 moves to the closing position and the opening position.
[0043] like Figure 1 As shown, the sliding member 30 can slide on the base 10 and can be switched between a closing position and an opening position.
[0044] As an example, Figure 1 As shown, the electric operating mechanism 100 further includes a slide rail 11. The slide rail 11 is mounted on the base 10, and the sliding member 30 can slide on the slide rail 11.
[0045] As another example, a slide groove is provided on the base 10 , and the sliding member 30 can slide along the slide groove on the base 10 .
[0046] The electric component 40 is coupled to the sliding member 30, and the electric component 40 may include components such as a motor 43 and gears. During the operation of the electric component 40, the sliding member 30 may be driven to switch between the closing position and the opening position. The motor 43 of the electric component 40 includes a first power supply terminal 431 and a second power supply terminal 432, and the first power supply terminal 431 and the second power supply terminal 432 can be connected to a power supply circuit.
[0047] The first micro switch 51 and the second micro switch 52 are arranged in parallel and fixed on the base 10 at one side of the delay assembly 20. In this way, during the rotation of the delay assembly 20, the protrusion 211 of the delay assembly 20 can abut against or separate from the first micro switch 51 and the second micro switch 52.
[0048] like Figure 4 As shown, each of the first micro switch 51 and the second micro switch 52 includes a normally-off contact 501, a normally-on contact 502, a moving contact 503 and an actuating member 504. In each micro switch, the normally-off contact 501 and the normally-on contact 502 are arranged in parallel, the moving contact 503 is arranged between the normally-off contact 501 and the normally-on contact 502, and the moving contact 503 can switch between the normally-off contact 501 and the normally-on contact 502. The actuating member 504 is coupled to the moving contact 503, and the actuating member 504 can drive the moving contact 503 to switch between the normally-off contact 501 and the normally-closed contact.
[0049] like Figure 4 As shown, the normally-on contact 502 of the first microswitch 51 and the normally-off contact 501 of the second microswitch 52 are connected to the first power supply terminal 431, the normally-off contact 501 of the first microswitch 51 and the normally-on contact 502 of the second microswitch 52 are connected to the second power supply terminal 432, and the moving contact 503 of the first microswitch 51 and the moving contact 503 of the second microswitch 52 are connected to the power supply circuit.
[0050] When the slider 30 is in the closing position (or the opening position), the protrusion 211 abuts against the first microswitch 51 and the second microswitch 52, thereby supplying power to the electric component 40 via the normally-off contact 501 of the first microswitch 51 and the normally-off contact 501 of the second microswitch 52. When the slider 30 is in the opening position (or the closing position), the protrusion 211 is separated from the first microswitch 51 and the second microswitch 52, thereby supplying power to the electric component 40 via the normally-on contact 502 of the first microswitch 51 and the normally-on contact 502 of the second microswitch 52.
[0051] With this arrangement, the delay component 20, the first micro switch 51 and the second micro switch 52 can adjust the power supply direction of the electric component 40 at the closing position and the opening position of the sliding member 30. When the power supply circuit is powered on again, the electric component 40 rotates in the opposite direction. The electric operating mechanism 100 can adjust the on and off of the power switch by reciprocating motion, thereby improving the opening and closing speed, thereby improving the response speed and stability of the power switch. At the same time, when adjusting the power supply direction of the electric component 40, there is no need to use a circuit board, which helps to save space inside the electric operating mechanism 100.
[0052] In some embodiments, Figure 2 As shown, the end of the sliding member 30 is provided with a first stopper 31 and a second stopper 32 , and the first stopper 31 and the second stopper 32 can adjust the position of the protrusion 211 of the delay assembly 20 .
[0053] like Figure 3 , Figure 5 and Figure 6 As shown, the delay assembly 20 includes a pin 23, a first turntable 21, and a second turntable 22. The pin 23 is fixed to the base 10. For example, a threaded structure is provided at one end of the pin 23, and a screw hole is provided on the base 10, and the pin 23 can be installed on the base 10 through the threaded structure. It should be understood that the pin 23 can also be installed on the base 10 by any achievable method such as a snap-fit structure, welding, etc., and the present disclosure is not intended to limit this.
[0054] The first turntable 21 is provided with a pin hole, into which the pin shaft 23 can be inserted, so that the first turntable 21 is rotatably connected to the pin shaft 23. A protrusion 211 is provided at the edge of the first turntable 21. During the rotation of the first turntable 21, the protrusion 211 can abut against or separate from the first micro switch 51 and the second micro switch 52. The second turntable 22 is arranged between the first turntable 21 and the base 10, and is rotatably connected to the pin shaft 23. The second turntable 22 is coupled to the first turntable 21. During the rotation of the second turntable 22, the second turntable 22 can drive the first turntable 21 to rotate. When the sliding member 30 is close to the closing position or the opening position, the second turntable 22 will drive the first turntable 21 to rotate, so as to achieve the delay effect.
[0055] like Figure 3 , Figure 5 and Figure 6 As shown, a first limit portion 221 and a second limit portion 222 are provided at the edge of the second rotating disk 22, and the movement trajectory of the first limit portion 221 is different from the movement trajectory of the second limit portion 222. For example, the first limit portion 221 is closer to the first rotating disk 21 than the second limit portion 222. The first stop portion 31 is provided on the movement trajectory of the first limit portion 221, and the second stop portion 32 is provided on the movement trajectory of the second limit portion 222. With this arrangement, during the movement of the sliding member 30, the first stop portion 31 can drive the first limit portion 221 to move, so that the protrusion 211 abuts against the first micro switch 51 and the second micro switch 52. The second stop portion 32 can drive the second limit portion 222, so that the protrusion 211 is separated from the first micro switch 51 and the second micro switch 52.
[0056] In some embodiments, Figure 5 and Figure 6As shown, the delay assembly 20 further includes an elastic member 24. One end of the elastic member 24 is coupled to the base 10, and the other end of the elastic member 24 is coupled to the second rotating disk 22. The elastic member 24 is configured to apply a force to the second rotating disk 22 to deviate from the dead point position.
[0057] like Figure 5 and Figure 6 As shown, the second rotating disk 22 is provided with ears at its edge, and the ears are provided with through holes, into which one end of the elastic member 24 is inserted. During the rotation of the second rotating disk 22, the ears can squeeze the elastic member 24, and the position where the elastic member 24 is subjected to the greatest force is the dead point position of the second rotating disk 22. In this way, under the action of the elastic member 24, the second rotating disk 22 can only switch between two extreme positions during the movement, at which the elastic member 24 is not squeezed by external force.
[0058] When the second rotating disk 22 moves to one extreme position, the protrusion 211 of the first rotating disk 21 can abut against the first micro switch 51 and the second micro switch 52. When the second rotating disk 22 moves to another extreme position, the protrusion 211 of the first rotating disk 21 can be separated from the first micro switch 51 and the second micro switch 52.
[0059] With this arrangement, the position of the sliding member 30 can be switched between the closing position and the opening position, which is converted into the protrusion 211 abutting against or separating from the first micro switch 51 and the second micro switch 52.
[0060] In some embodiments, Figure 5 and Figure 6 As shown, two third limiting portions 223 are provided on the side of the second rotating disk 22 facing the first rotating disk 21 , and a fourth limiting portion 212 is provided on the side of the first rotating disk 21 facing the second rotating disk 22 , and the fourth limiting portion 212 is located between the two third limiting portions 223 .
[0061] As an example, Figure 5 and Figure 6 As shown, two limit plates are provided on the side of the second rotating disk 22 facing the first rotating disk 21, and a sector-shaped area is provided between the two limit plates. A columnar fourth limit portion 212 is provided on the side of the first rotating disk 21 facing the second rotating disk 22, and the fourth limit portion 212 is located between the two limit plates. During the rotation of the second rotating disk 22, the first rotating disk 21 and the second rotating disk 22 do not rotate simultaneously, but start to move after the fourth limit portion 212 contacts the limit plates.
[0062] When the sliding member 30 moves toward the closing position, the fourth limiting portion 212 and a limiting plate (for example, Figure 5The second rotating disk 22 is in a dead point position. When the second rotating disk 22 continues to rotate, the second rotating disk 22 deviates from the dead point position. Under the action of the elastic member 24, the second rotating disk 22 quickly rotates to the limit position on one side, and the first rotating disk 21 drives the protrusion 211 to abut against the first micro switch 51 and the second micro switch 52.
[0063] When the sliding member 30 moves toward the opening position, the fourth limiting portion 212 and another limiting plate (for example, Figure 5 The second rotating disk 22 is in a dead point position. When the second rotating disk 22 continues to rotate, the second rotating disk 22 deviates from the dead point position. Under the action of the elastic member 24, the second rotating disk 22 quickly rotates to the limit position on the other side. At this time, the first rotating disk 21 drives the protrusion 211 to separate from the first micro switch 51 and the second micro switch 52.
[0064] With this arrangement, the delay assembly 20, the first micro switch 51 and the second micro switch 52 can adjust the power supply direction of the electric assembly 40 at the closing position and the opening position of the sliding member 30. When the power supply circuit is powered on again, the electric assembly 40 rotates in the opposite direction. The electric operating mechanism 100 can adjust the on and off of the power switch by reciprocating motion, thereby increasing the opening and closing speed, thereby increasing the response speed and stability of the power switch.
[0065] In some embodiments, Figure 7 As shown, the sliding member 30 is provided with a guide groove 33 , and the guide groove 33 can be connected to the electric component 40 , so as to slide along the base 10 under the drive of the electric component 40 .
[0066] like Figure 7 As shown, the electric assembly 40 includes a main shaft 41, a cam 42 and a motor 43. An axial hole is provided on the base 10, and the main shaft 41 can rotate in the axial hole. The cam 42 is arranged between the main shaft 41 and the sliding member 30, and the cam 42 is coupled to the main shaft 41. A protrusion 421 is provided on the side of the cam 42 facing the sliding member 30, and the protrusion 421 is inserted into the guide groove 33 of the sliding member 30. The motor 43 is coupled to the main shaft 41, and the motor 43 can drive the main shaft 41 to rotate, so that the sliding member 30 switches between the closing position and the opening position.
[0067] like Figure 7 As shown, the motor 43 is connected to the main shaft 41 through a gear, and the motor 43 can drive the main shaft 41 to rotate, thereby driving the cam 42 at the end of the main shaft 41 to rotate. The protrusion 421 on the cam 42 can slide in the guide groove 33 of the sliding member 30, and due to the curved structure of the guide groove 33, the sliding member 30 can slide along the base 10.
[0068] like Figure 4As shown, the motor 43 includes a first power supply terminal 431 and a second power supply terminal 432. The normally-on contact 502 of the first micro switch 51 and the normally-off contact 501 of the second micro switch 52 are connected to the first power supply terminal 431, and the normally-off contact 501 of the first micro switch 51 and the normally-on contact 502 of the second micro switch 52 are connected to the second power supply terminal 432.
[0069] When the slider 30 is in the closed position, the protrusion 211 abuts against the first microswitch 51 and the second microswitch 52, so that power is supplied to the motor 43 via the normally-off contact 501 of the first microswitch 51 and the normally-off contact 501 of the second microswitch 52. When the slider 30 is in the open position, the protrusion 211 is separated from the first microswitch 51 and the second microswitch 52, so that power is supplied to the motor 43 via the normally-on contact 502 of the first microswitch 51 and the normally-on contact 502 of the second microswitch 52.
[0070] In some embodiments, Figure 7 As shown, the electric assembly 40 further includes a driven wheel 44 and a driving wheel 45. The driven wheel 44 is coupled to the main shaft 41, and the edge of the driven wheel 44 is provided with a first sector tooth portion 441. The driving wheel 45 is coupled to the drive shaft of the motor 43, and the edge of the driving wheel 45 is provided with a second sector tooth portion 451.
[0071] like Figure 7 As shown, the first sector-shaped tooth portion 441 can mesh with the second sector-shaped tooth portion 451, and the position of the sliding member 30 can be adjusted in a reciprocating manner, thereby improving the response speed and stability of the power switch.
[0072] In some embodiments, Figure 2 As shown, a driving part 411 is provided at one end of the main shaft 41 away from the cam 42, and the driving part 411 provides a position for the user to manually rotate the main shaft 41. When the user operates the driving part 411, the driving part 411 can rotate the main shaft 41, thereby driving the sliding member 30 to switch between the closing position and the opening position.
[0073] As an example, Figure 1 , Figure 2 and Figure 8 As shown, the driving portion 411 is a groove, and the groove is suitable for inserting the operating member 200. In this way, the user can insert the handheld operating member 200 (for example, a handle or a screwdriver) into the groove, thereby driving the rotation of the main shaft 41 and the position switching of the sliding member 30. At the same time, after the operating member 200 is inserted into the groove, the groove can ensure that the operating member 200 and the main shaft 41 form an effective and stable connection, so as to ensure that the force or torque can be accurately transmitted.
[0074] In some embodiments, Figure 1and Figure 2 As shown, the electric operating mechanism 100 further includes an indicator plate 412. The indicator plate 412 is disposed at one end of the main shaft 41 away from the cam 42, and the indicator plate 412 is coupled to the main shaft 41. The indicator plate 412 is provided with a mark indicating the angle change of the indicator plate 412.
[0075] like Figure 1 and Figure 2 As shown, when the main shaft 41 rotates, the indicator plate 412 will rotate accordingly, and the mark on the indicator plate 412 can be used to indicate the rotation angle of the indicator plate 412. In this way, when the user manually rotates the main shaft 41, the mark on the indicator plate 412 can be used to determine whether the operation is in place.
[0076] As an example, more than two sector-shaped areas are divided on the indicator disk 412. For example, a green mark is set in one sector-shaped area to indicate that the sliding member 30 is in the closed position, and a red mark is set in another sector-shaped area to indicate that the sliding member 30 is in the open position, and so on.
[0077] In one embodiment, the indicator disk 412 may be a color disk. In other embodiments, the indicator disk 412 may be any other suitable type. It should be understood that scales, numbers, letters or any other easily distinguishable marks may also be provided on the indicator disk 412, and the present disclosure is not intended to be limited thereto.
[0078] In some embodiments, Fig. 9 As shown, a boss 442 is provided on one side of the driven wheel 44 facing the base 10, and the electric operating mechanism 100 further includes a third micro switch 53. The third micro switch 53 is provided on one side of the main shaft 41 and is coupled to the base 10. The third micro switch 53 is electrically connected to the motor 43. During the rotation of the main shaft 41, the third micro switch 53 can abut against or separate from the boss 442, thereby controlling the on and off of the power supply of the motor 43.
[0079] like Fig. 9 As shown, a sleeve is provided on the side of the driven wheel 44 facing the base 10, and a boss 442 is provided on the outer edge of the sleeve. During the rotation of the main shaft 41, the boss 442 rotates around the main shaft 41. In this process, the boss 442 can abut against or separate from the actuator 504 of the third micro switch 53. When the driven wheel 44 rotates to a certain angle, the boss 442 abuts against the third micro switch 53, and the circuit is turned on. In this way, the angle of the driven wheel 44 can be determined by the positional relationship between the third micro switch 53 and the boss 442, and the situation of over-limit or under-position movement can be avoided, thereby accurately controlling the movement of the sliding member 30 between the closing position and the opening position.
[0080] In a second aspect of the present disclosure, a power switch is provided. The power switch comprises a body and an electric operating mechanism 100 according to the first aspect of the present disclosure. The body has an operating handle, and a sliding member 30 of the electric operating mechanism 100 is coupled to the operating handle, which can drive the operating handle to switch between a closing position and an opening position.
[0081] As an example, the body of the power switch may be a circuit breaker, and the circuit breaker includes an operating handle. The sliding member 30 is connected to the operating handle, and can control the opening and closing of the circuit breaker.
[0082] It should be understood that the body of the power switch may also be any switch that can be driven by an operating handle, such as a load switch, an isolating switch, a dual power switching switch, etc., and the embodiments of the present disclosure are not intended to be limited to this.
[0083] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
