DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0049] It should be noted that the following embodiments can be combined if there is no conflict.

[0050] Circuit breakers are widely used in electrical circuits. Circuit breakers will trip in the event of a short circuit or severe overload to cut off the circuit, thereby effectively protecting the electrical appliances in the circuit. The tripping structure is the core component of the circuit breaker, and the accuracy of the button indication position affects the user's use and safety.

[0051] To solve the problem that the leakage indication button in the existing tripping structure is affected by the vibration of the product during the opening and closing process, resulting in errors in the indication position. The embodiment of the utility model provides a tripping structure, in which the button and the top rod of the tripping structure are independent of each other, and the button and the top rod are linked through a pull rod. The button and the top rod are not in direct contact. When the circuit breaker leaks electricity, the button is separated from the top rod and the pull rod, and the vibration of the product will not be transmitted to the button through the top rod. Therefore, during the opening and closing process of the product, the vibration of the product will not be transmitted to the button through the top rod, and the button will not shake in the pressing direction, thereby effectively ensuring the leakage indication function and improving user usability.

[0052] Specifically, see Figures 1 to 7 The present invention provides a tripping structure 200, which may include a bracket 1, a button 2, a push rod 3 and a pull rod 4. The button 2 is pressed in the direction ( Figure 2 The push rod 3 is rotatably connected to the bracket 1, and the push rod 3 is independently arranged relative to the button 2, that is, the push rod 4 and the button 3 are two independent structures. The pull rod 4 is used to transfer the button 2 and the push rod 3. In this embodiment, the pull rod 4 may include a protrusion 41.

[0053] See also Figure 5 In this embodiment, the button 2 is provided with a receiving portion 241. In the normal working state, the projection 41 cooperates with the receiving portion 241, and one end of the projection 41 abuts against the top rod 3. Figure 1 and Figure 3As shown, in this embodiment, the trip structure 200 is in a normal working state, the button 2 is in a pressed state, and the protrusion 41 is received in the accommodating portion 241. The protrusion 41 can limit the button 2 and keep the button 2 in a pressed state, and the pressed state indicates that the circuit breaker is working normally. At the same time, due to the limiting effect of the protrusion 41 on the button 2, in a normal working state, the vibration of the product will not be transmitted to the button 2 through the push rod 3, ensuring that the button 2 indicates the accurate position.

[0054] When the circuit breaker leaks electricity, the protrusion 41 separates from the accommodating portion 241. Since the limit of the protrusion 41 on the accommodating portion 241 disappears, the button 2 will switch from the pressed state to the pop-up state, and the pop-up state indicates that the circuit breaker is leaking electricity. At the same time, the button 2 is separated from the pull rod 4 and the top rod 3. During the circuit breaker leakage process, the button 2 is separated from the top rod 3, and the vibration of the product will not be transmitted to the button 2 through the top rod 3, effectively ensuring the leakage indication function.

[0055] In this embodiment, the moving direction of the protrusion 41 is perpendicular to the pressing direction of the button 2, so that under normal working conditions, the accommodating portion 241 is effectively limited by the protrusion 41. Figure 2 The X-axis direction shown in FIG. 2 moves leftward, driving the protrusion 41 to separate from the receiving portion 241 .

[0056] In the embodiment of the utility model, the structures of the button 2 and the push rod 3 are independent of each other, and the two are linked by the pull rod 3 without direct contact. The vibration of the product during the opening and closing process will not be transmitted to the button 2 through the push rod 3, and the button 2 will not be affected by the opening and closing vibration to indicate the position error, which effectively reduces the shaking of the button 2 in the pressing direction, thereby effectively ensuring the leakage indication function, avoiding indication risks, improving user usability, and avoiding safety risks.

[0057] The implementation method of driving the pull rod 4 to move can be designed as needed. For example, in some embodiments, see Figure 2 The tripping structure 200 in the embodiment of the utility model may also include a coil 5, which is disposed in the bracket 1. Furthermore, the pull rod 4 also includes a rod body 42 and an iron core 44 connected to the rod body, and the protrusion 41 is disposed on one side of the rod body 42. In this embodiment, when the circuit breaker leaks electricity, the coil 5 is energized, and the iron core 44 drives the rod body 42 to move under the magnetic attraction of the coil 5, thereby driving the protrusion 41 to slide out of the accommodation portion 241. Figure 2 As shown, after the coil 5 is energized, the iron core 44 is attracted, and the iron core 44 drives the rod body 42 along the direction as shown in FIG. Figure 2 The X-axis direction in FIG. 2 moves to the left, so that the protrusion 41 slides out of the receiving portion 241, and the button 2 switches from the pressed state to the popped state, that is, the tripping structure 200 is Figure 1 and Figure 3The structure shown is switched to Figure 2 and Figure 4 In the process of the pull rod 4 moving to the left, the pull rod 4 abuts against the top rod 3 and rotates counterclockwise.

[0058] Optionally, the protrusion 41 and the iron core 44 are respectively arranged on both sides of the rod body 42. Such a design can make the rod body 42 move more smoothly in the X-axis direction.

[0059] See also Figure 2 and Figure 7 , a mounting portion 421 may be provided on one side of the rod body 42, and the iron core 44 is inserted into the mounting portion 421. It should be understood that the iron core 44 may also be connected to the mounting portion 421 by other means such as snaps. In this embodiment, the mounting portion 421 and the protrusion 41 are respectively provided on the inner and outer sides of the rod body 42, so that the protrusion 41 and the iron core 44 are respectively provided on both sides of the rod body 42. Figure 2 In the illustrated embodiment, the protrusion 41 is disposed on the outer side of the rod body 42 , and the iron core 44 is disposed on the inner side of the rod body 42 , so that the rod body 42 can move more smoothly in the X-axis direction.

[0060] See also Figure 7 The pull rod 4 may also include a release portion 43 bent and connected to the rod body 42. A release hook 431 is provided at one end of the release portion 43 away from the rod body 42. The release hook 431 is used to cooperate with a release rod (not shown) of the product. When the circuit breaker leaks electricity, the coil 44 is energized to attract the iron core 44, driving the rod body 42 and the release portion 43 to move to the left along the X-axis direction, and the release hook 431 drives the release rod to release, thereby achieving product release.

[0061] The protrusion 41 , the rod body 42 and the release portion 43 in this embodiment are an integrally formed structure, which is convenient for processing.

[0062] Optionally, the release portion 43 is bent upward relative to the rod portion 42 to better adapt to the structure of the product. It should be understood that the bending direction of the release portion 43 relative to the rod portion 42 can also be designed to be other as needed to adapt to different product requirements.

[0063] The protrusion 41 can be arranged on the outer side of the end of the rod body 42 away from the release part 43, and the mounting part 421 can be arranged on the inner side of the end of the rod body close to the release part 43. Such a design ensures that the pull rod 4 can move smoothly along the X-axis direction.

[0064] See also Figure 7, the protrusion 41 in this embodiment is inverted. The protrusion 41 is provided with an abutting end 411, and under normal working conditions, the abutting end 411 abuts against the top rod 3. With such a design, the top rod 3 can limit the protrusion 41. When the circuit breaker leaks electricity, the protrusion 41 slides out of the accommodating portion 241, and the abutting end 411 presses the top rod 3 to rotate counterclockwise until the protrusion 41 is completely separated from the accommodating portion 241. At this time, the button 2 is separated from the pull rod 4, and the button 2 is also separated from the top rod 3, and the protrusion 41 and the top rod 3 remain in abutment; when the circuit breaker contacts the leakage, the top rod 3 rotates clockwise, and the top rod 3 will push the protrusion 41 to gradually slide into the accommodating portion 241 until the protrusion 41 limits the accommodating portion 241 again.

[0065] In this embodiment, a guide surface 412 is provided on one side of the protrusion 41 away from the abutting end 411, and the guide surface 412 is inclined. The guide surface 412 cooperates with the corresponding edge of the lower surface of the accommodating portion 241, so that the protrusion 41 can slip out of or slide into the accommodating portion 241. By providing the guide surface 412, the protrusion 41 can slide out of or slide into the accommodating portion 241 more smoothly, reducing the influence of the vibration generated by the protrusion 41 sliding out of or into the accommodating portion 241 on the indicated position of the button 2. Optionally, the corresponding edge of the lower surface of the accommodating portion 241 is in a rounded state, and the guide surface 412 and the corresponding edge of the lower surface of the accommodating portion 241 can move more smoothly. Figure 5 As shown, the accommodation portion 241 in this embodiment is a groove with two ends penetrating therethrough, and the guide surface 412 cooperates with the lower edge of the groove facing one end of the push rod, so that the protrusion 41 can slide in or out from one end of the groove.

[0066] See also Figure 6 and Figure 7 , the abutting end 411 may be provided with a protrusion 4111 and a first recess 4112, and the top rod 3 is provided with a second recess 331. Under normal working conditions, Figure 3 As shown, the protrusion 4111 abuts against the second recess 331, stably confining the protrusion 41 in the accommodating portion 241 to prevent the button 2 from shaking. When the circuit breaker leaks electricity, the protrusion 41 moves to the left under the drive of the rod body 42, driving the protrusion 4111 to slide out of the second recess 331 until the first recess 4112 is opposite to the second recess 331; when the button is pressed again, the top rod 3 rotates clockwise, which can more easily drive the protrusion 4111 to slide into the second recess 331 to drive the protrusion 41 to move rightward and reset. The protrusion 4111 and the first recess 4112 in this embodiment are smoothly connected.

[0067] It should be understood that the matching relationship between the abutting end 411 and the push rod 3 is not limited to the above structure, and other matching structures can also be set.

[0068] See again Figures 1 to 4The tripping structure 200 of the embodiment of the utility model may further include a first elastic member 6, one end of the first elastic member 6 is connected to one end of the top rod 3, and the other end is connected to the other end of the top rod 3. By providing the first elastic member 6, the top rod 4 can be prevented from rotating due to accidental touch; on the other hand, when the circuit breaker releases the leakage, the first elastic member 6 is reset, which can drive the top rod 3 to reset.

[0069] In this embodiment, when the circuit breaker releases the leakage, the top rod 3 rotates under the rotational thrust generated when the mechanism rocker arm is rotated and the elastic force of the first elastic member 6, and the protrusion 41 gradually slides into the accommodating portion 241 under the push of the top rod 3, and the protrusion 41 again limits the accommodating portion 241, so that the button 2 switches from the pop-up state to the pressed state. Specifically, when the circuit breaker contacts the leakage, the mechanism rocker arm is rotated clockwise, driving the top rod 3 to rotate clockwise. Combined with the reset effect of the first elastic member 6, the top rod 3 rotates clockwise, and the top rod 3 pushes the protrusion 41 to move to the right along the X-axis direction. The protrusion 41 gradually slides into the accommodating portion 241 until the top rod 3 is limited by the bracket 1. The mechanism rocker arm can be a part of the tripping structure 200, or a part of the circuit breaker, or a part of the product; it should be understood that the mechanism rocker arm can also be set independently.

[0070] In this embodiment, the first elastic member 6 may be a torsion spring or other types of elastic members.

[0071] It should be understood that in some other embodiments, the top rod 3 itself can be an elastic structure without the need to additionally provide the first elastic member 6, and the elastic force of the top rod 3 itself can prevent the top rod 4 from rotating due to accidental touch.

[0072] In this example, see Figure 6 The push rod 3 may include a first rod body 31, a second rod body 32 bent and connected to the first rod body 31, and a bent portion 33 provided at one end of the second rod body 32 away from the first rod body 31. With such a structural design, the push rod 4 can better transmit the rotational force to the pull rod 4, thereby driving the button 2 to reset.

[0073] In normal working state, the abutting end 411 abuts against the bending portion 33. Optionally, one end of the first elastic member 6 is connected to the end of the first rod 31 away from the second rod 32, and the other end abuts against the bending portion 33. In some embodiments, the first elastic member 6 can be a torsion spring, the spiral portion of the torsion spring is connected to the end of the first rod 31 away from the second rod 32, and the connecting rod of the torsion spring is connected to the bottom of the connection between the bending portion 33 and the second rod 32. The second recess 331 is provided at the top of the connection between the bending portion 33 and the second rod 32.

[0074] Optionally, the angle between the first rod body 31 and the second rod body 32 is greater than 90 degrees and less than 180 degrees. In this way, when the leakage is released and the button is buckled again, the top rod 3 can better transmit the rotational force to reset the button 2. For example, the angle between the first rod body 31 and the second rod body 32 can be set to 120 degrees.

[0075] See also Figure 1 and Figure 3 The bracket 1 may be provided with a connecting member 111, which is used to rotatably connect the top rod 3 to the bracket 1. The connecting member 11 can serve as the rotation center of the top rod 3. Figure 1 , Figure 3 and Figure 4 as well as Figure 6 The end of the first rod body 31 away from the second rod body 32 may be provided with a mounting hole 311, and one end of the connecting member 111 cooperates with the mounting hole 311, so that the push rod is rotatably connected to the bracket. When the circuit breaker contacts leakage, the mechanism rocker arm is rotated clockwise, driving the push rod 3 to rotate clockwise. Combined with the reset effect of the first elastic member 6, the push rod 3 rotates clockwise around the connecting member 111, and the push rod 3 pushes the protrusion 41 to move rightward along the X-axis direction, and the protrusion 41 gradually slides into the accommodating portion 241 until the push rod 3 is limited by the bracket 1.

[0076] See also Figure 2 The tripping structure 200 of the embodiment of the utility model may also include a second elastic member 7, and the expansion and contraction direction of the second elastic member 7 is parallel to the X-axis direction. In this embodiment, one end of the second elastic member 7 is connected to the coil 5, and the other end is connected to the mounting portion 421, and the second elastic member is sleeved on the iron core 44. When the circuit breaker releases the leakage and the product is released again, the top rod 3 rotates clockwise under the rotational thrust generated when the mechanism rocker arm is rotated and the elastic reset force of the first elastic member 6, and the top rod 3 pushes the protrusion 41 to move toward the accommodating portion 241 until the top rod 3 is limited by the bracket 1, and the second elastic member 7 is reset. The rod body 42 moves to the right under the elastic reset force of the second elastic member 7, driving the protrusion 41 to move to the right until the protrusion 41 slides into the accommodating portion 241, and the button 2 is switched from the pop-up state to the pressed state.

[0077] Specifically, when the circuit breaker leaks electricity, the coil 5 is energized, and the magnetic force generated by the coil 5 will attract the iron core 44. The iron core 44 moves to the left under the magnetic attraction of the coil 5, and the second elastic member 7 is compressed. The iron core 44 gradually approaches the coil 5, driving the rod body 42 to move to the left to make the product disengaged, and at the same time, it also drives the protrusion 41 to move to the left synchronously until the protrusion 41 disengages from the accommodating portion 241, and the button 2 switches from the pressed state to the pop-up state, and the abutment end 411 presses the push rod 3 to make the push rod 3 rotate counterclockwise.

[0078] When the leakage fault is removed and the product is buckled again, the coil 5 is de-energized, and the rotation thrust generated when the mechanism rocker arm is rotated will be transmitted to the push rod 3. Combined with the reset function of the first elastic member 6, the push rod 3 rotates clockwise, pushing the protrusion 41 to move to the right. After the push rod 3 rotates clockwise to a certain angle, the push rod 3 is limited by the bracket 1 and cannot continue to rotate. Then, the iron core 44 and the rod body 42 continue to move to the right under the elastic reset force of the second elastic member 7 until the protrusion 41 is accommodated in the accommodating portion 241, and the button 2 switches from the pop-up state to the pressed state.

[0079] By providing the second elastic member 7 , when there is a leakage, the iron core 44 can move relatively smoothly to the left toward the coil 5 ; when the button is pressed again, the elastic restoring force of the second elastic member 7 can reset the button 2 .

[0080] The second elastic member 7 may be a spring or other types of elastic members.

[0081] See also Figures 1 to 5 The button 2 in the embodiment of the utility model may include a pressing portion 21, a third elastic member 22, a connecting rod 23 and a moving rod 24. The pressing portion 21 is connected to the moving rod 24 through the connecting rod 23. Specifically, one end of the connecting rod 23 is connected to the top of the moving rod 24, and the pressing portion 21 is arranged at the other end of the connecting rod 23. The pressing portion 21 of this embodiment is connected to the bracket 1 through the third elastic member 22, and the moving rod 24 can move along the pressing direction, thereby driving the pressing portion 21 to switch between the pressing state and the pop-up state.

[0082] In this embodiment, the connecting rod 23 and the moving rod 24 are surrounded outside the bracket 1, and the structure is reasonable and compact.

[0083] The accommodation portion 241 is disposed on the moving rod 24 . Specifically, the accommodation portion 231 is disposed on the inner side of the moving rod 24 .
