In order to better understand the technical solutions of the present application, the following description will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings.

The present embodiment provides a driving mechanism 122 applied to an operating device 12 of a circuit breaker 1. Referring to fig. 1 to 4, fig. 1 is an exploded view of an interrupt router 1 according to some embodiments of the present application, fig. 2 is a schematic view of an operating device 12 according to some embodiments of the present application, fig. 3 is a schematic view of a driving mechanism 122 according to some embodiments of the present application, and fig. 4 is an exploded view of the driving mechanism 122 according to some embodiments of the present application.

As shown in fig. 1, the circuit breaker 1 of the embodiment of the present application may include a circuit breaker body 11 and an operating device 12. In the process of using the circuit breaker 1, in order to improve the use safety performance of the circuit breaker 1, the circuit breaker body 11 is usually installed inside a cabinet, and the operating device 12 is installed outside the cabinet, so that the operating device 12 can be operated outside the cabinet to switch on and switch off the circuit breaker body 11 inside the cabinet.

When the operating device 12 is operated to open and close the breaker body 11, as shown in fig. 2, it is generally necessary to drive the opening and closing handle 112 of the breaker body 11 by a driving mechanism 122 inside the operating device 12, so that the opening and closing handle 112 drives a mechanism inside the breaker body 11 to act, thereby opening or closing the breaker body 11.

When the drive mechanism 122 drives the opening/closing lever 112, the drive manner of the opening/closing lever 112 by the drive mechanism 122 is different depending on the specific form of the drive mechanism 122. For example, the driving mechanism 122 in the related art includes a manual driving mechanism and an electric driving mechanism; wherein, in the manual driving mechanism, the handle, the push plate and the fixed shaft are arranged, so that the handle can push the push plate, the push plate can rotate around the fixed shaft and the opening and closing handle 112 is driven; in the electric driving mechanism, the motor, the gear and the pushing member are arranged, so that the motor can drive the pushing member through the gear, and the pushing member can drive the opening and closing handle 112.

However, in the related art, in order to reduce the probability of electric shock, the opening and closing handle 112 is generally made of a plastic material, and in order to secure the strength of the driving mechanism 122, a push plate or pusher driving the opening and closing handle 112 is generally made of a metal material. Based on this, it can be found that, when the push plate or pusher drives the opening and closing handle 112, the contact between the push plate or pusher and the opening and closing handle 112 is a contact between a metal material and a plastic material, and in this contact form, it is expected that as the number of driving times increases, the scratch and abrasion of the opening and closing handle 112 by the push plate or pusher also increases, resulting in a reduction in the service life of the circuit breaker 1.

Based on this, the present embodiment provides a driving mechanism 122, as shown in fig. 3 and 4, the driving mechanism 122 includes: a driving handle 1221, a rotation shaft 1222, and a driving member 1223, the driving member 1223 being driven by the driving handle 1221 to rotate about the rotation shaft 1222. The driving member 1223 includes a receiving groove 1223A for receiving the opening and closing handle 112 of the breaker body 11, a driving block 1224 made of a rubber-plastic material is disposed on a groove wall of the receiving groove 1223A, and when the driving member 1223 rotates around the rotation shaft 1222, the driving block 1224 pushes the opening and closing handle 112 to open or close the breaker body 11.

When the driving member 1223 is driven by the driving handle 1221 to rotate around the rotation axis 1222, the driving member 1223 may be disposed in driving connection with the driving handle 1221, and the driving member 1223 may be disposed in rotational connection with the rotation axis 1222, that is, the driving member 1223 may be forced by the driving handle 1221 to rotate the driving member 1223 around the rotation axis 1222 under the force applied by the driving handle 1221.

In addition, the driving block 1224 made of a rubber-plastic material refers to that the driving block 1224 is made of a rubber-plastic material, wherein the rubber-plastic material may be plastic or rubber.

Based on the above arrangement, when the driving mechanism 122 drives the opening and closing handle 112, the driving member 1223 can be driven by the driving handle 1221 to rotate around the rotation shaft 1222, and drive the driving block 1224 made of rubber plastic material to push the opening and closing handle 112 to open or close the breaker body 11. In this driving process, it can be found that the contact between the opening and closing handle 112 and the driving member 1223 in the related art is converted into the contact between the opening and closing handle 112 and the driving block 1224, that is, the contact between the plastic material and the metal material can be converted into the contact between the plastic material and the rubber-plastic material, so that the scratch and abrasion of the opening and closing handle 112 can be reduced, and the service life of the circuit breaker 1 can be prolonged.

The receiving groove 1223A may be a blind groove or a through groove. The size of the receiving groove 1223A needs to be larger than the size of the opening and closing handle 112 so that the opening and closing handle 112 can be received in the receiving groove 1223A. The receiving groove 1223A may be provided in various shapes, for example, a circular groove, a polygonal groove, a fan-shaped groove, or the like, which is not particularly limited in this application.

The driving block 1224 may be disposed on a sidewall of the accommodating groove 1223A when disposed on a groove wall of the accommodating groove 1223A, where the sidewall is a wall adjacent to the opening of the accommodating groove 1223A, and may be disposed in various manners when specifically disposed. For example, in some arrangements, when the receiving groove 1223A is provided as a circular groove, the driving block 1224 may be provided as a circular ring structure that fits into the circular groove to be provided to the entire groove wall of the receiving groove 1223A. In other arrangements, when the receiving groove 1223A is configured as a polygonal groove, the driving block 1224 may be configured as a straight-line structure to be disposed at one groove wall of the receiving groove 1223A or as a polygonal structure to be disposed at the entire groove wall of the receiving groove 1223A. In still other arrangements, when the receiving groove 1223A is configured in a fan-shaped configuration, the driving block 1224 may be configured in a straight-line configuration, an arc-shaped configuration, or a fan-shaped annular configuration, when the driving block 1224 is configured in a straight groove wall of the receiving groove 1223A, when the driving block 1224 is configured in an arc-shaped configuration, may be configured in an arc-shaped groove wall of the receiving groove 1223A, and when the driving block 1224 is configured in a fan-shaped annular configuration, may be configured in an entire groove wall of the receiving groove 1223A.

Based on the foregoing, since the driving piece 1223 is rotationally moved by the driving action of the driving handle 1221, and, in general, the opening and closing handle 112 is provided in a substantially plate-like structure, in order to secure the direction of the force applied by the driving block 1224 to the opening and closing handle 112 and to achieve stable pushing, the embodiment of the present application may provide the accommodation groove 1223A as a polygonal groove or a fan-shaped groove, and provide the straight groove wall opposite to the plate surface of the opening and closing handle 112 and provide the driving block 1224 to the straight groove wall when the accommodation groove 1223A is a polygonal groove or a fan-shaped groove.

On this basis, considering that the opening and closing handle 112 is reciprocated between two fixed positions during the driving, two opposite straight groove walls of the receiving groove 1223A are required to push against the opening and closing handle 112 during the reciprocation. Therefore, in this embodiment, the driving block 1224 may be disposed on at least one of the two straight slot walls, that is, the opening and closing handle 112 may be located between the first slot wall A1 and the second slot wall A2 that are disposed opposite to each other, and the first slot wall A1 and the second slot wall A2 are opposite to the driven surface of the opening and closing handle 112, where the driving block 1224 is disposed on the first slot wall A1 and/or the second slot wall A2, so that during the reciprocating motion of the opening and closing handle 112, at least one plate surface of the opening and closing handle 112 may be driven by the driving block 1224, so as to reduce the probability that the opening and closing handle 112 is scratched and worn by the driving member 1223. It should be emphasized that the opposite arrangement of the first slot wall A1 and the second slot wall A2 does not mean that the first slot wall A1 and the second slot wall A2 are parallel, and in fact, the first slot wall A1 and the second slot wall A2 may be disposed at an included angle.

It should be noted that, when the driving blocks 1224 are disposed on the first slot wall A1 and the second slot wall A2, one driving block 1224 may be disposed on the first slot wall A1 and the second slot wall A2, so that two surfaces of the opening and closing handle 112 are pushed by the two driving blocks 1224 alternately during the reciprocating motion of the opening and closing handle 112, at this time, the opening and closing handle 112 will not contact with the driving member 1223 or be worn by the driving member 1223, so that the service life of the opening and closing handle 112 can be greatly prolonged.

Further to the above embodiment, with continued reference to fig. 3 and 4, the surface of the driving block 1224 for contacting the opening/closing handle 112 is configured as an arc surface, which protrudes toward the opening/closing handle 112.

Based on the foregoing, the driving block 1224 may rotate with the driving piece 1223, and thus, if the surface of the driving block 1224 contacting the opening and closing handle 112 is configured as a plane, the entire plane of the driving block 1224 facing the opening and closing handle 112 may contact the opening and closing handle 112 during driving, that is, the entire plane of the driving block 1224 facing the opening and closing handle 112 may rub against the opening and closing handle 112, which may increase wear of the opening and closing handle 112 by the driving block 1224.

Therefore, in this embodiment, by configuring the surface of the driving block 1224 that is used for contacting the opening and closing handle 112 as an arc surface protruding toward the opening and closing handle 112, during the rotation of the driving block 1224 along with the driving member 1223, different portions of the arc surface can be pushed against different portions of the opening and closing handle 112, that is, the contact portion between the driving block 1224 and the opening and closing handle 112 is always changed, and compared with the contact between the driving block 1224 and the opening and closing handle 112 along the whole plane of the driving block 1224 facing the opening and closing handle 112, the contact area between the driving block 1224 and the opening and closing handle 112 is greatly reduced, the friction between the driving block 1224 and the opening and closing handle 112 is also greatly reduced, and the abrasion of the driving block 1224 on the handle is also greatly reduced.

In addition to the foregoing embodiments, when the driving block 1224 is disposed on the slot wall, there may be various manners of disposing the driving block 1224 and the slot wall, and the following description will be given by way of example.

In some embodiments, as shown in fig. 5, one of the driving block 1224 and the slot wall is provided with a clamping slot J2, and the other is provided with a clamping table J1 adapted to the clamping slot J2, and the clamping slot J2 is used for clamping with the clamping table J1, so as to mount the driving block 1224 on the slot wall.

The engagement groove J2 and the engagement table J1 are structures for attaching the drive block 1224 to the groove wall. The clamping groove J2 may be formed in the groove wall, the clamping table J1 may be formed in the driving block 1224, or the clamping groove J2 may be formed in the driving block 1224, and the clamping table J1 may be formed in the groove wall, which is not particularly limited in this application.

The clamping groove J2 and the clamping table J1 may be provided in various structural forms, for example, long strip, arc, or combination of long strip and arc, which is not particularly limited in this application, so long as the clamping groove J2 and the clamping table J1 are adapted.

After the driving block 1224 is mounted on the slot wall through the clamping slot J2 and the clamping table J1, the driving block 1224 is not easy to move or slide on the slot wall under the friction action of the driving block 1224 and the slot wall, which is beneficial to ensuring the contact between the driving block 1224 and the opening and closing handle 112.

In other arrangements, further to the foregoing arrangements, referring to fig. 5, the driving mechanism 122 further includes a connecting member 1225, the driving block 1224 is further provided with a first mounting hole K1, the driving member 1223 is further provided with a second mounting hole K2 opposite to the first mounting hole K1, and the connecting member 1225 is mounted to the first mounting hole K1 and the second mounting hole K2 to fix the driving block 1224 to the driving member 1223.

The connecting member 1225 is a member for fixing the driving block 1224 and the driving member 1223. The connector 1225 may be a rivet or bolt; when the connecting member 1225 is a rivet, both the first and second mounting holes K1 and K2 may be light holes; when the connection member 1225 is a bolt, the first mounting hole K1 may be a light hole and the second mounting hole K2 may be a screw hole.

The first mounting hole K1 may be a through hole penetrating the driving block 1224, the second mounting hole K2 may be a through hole penetrating the driving member 1223, the penetrating direction of the first mounting hole K1 and the penetrating direction of the second mounting hole K2 are the same, and the penetrating direction is parallel to the surface of the driving block 1224, which is used for contacting with the opening and closing handle 112, so that the surface of the driving block 1224, which is used for contacting with the opening and closing handle 112, can be affected by the connecting member 1225, the first mounting hole K1 and the second mounting hole K2, and the contact efficiency of the driving block 1224 and the opening and closing handle 112 is improved.

After the connecting piece 1225 fixes the driving block 1224 on the driving piece 1223, the possibility that the driving block 1224 moves or slides on the driving piece 1223 can be further reduced, so as to further ensure the contact efficiency of the driving block 1224 and the opening and closing handle 112.

On the basis of the previous embodiments, there are also various connection modes when the driving member 1223 is in driving connection with the driving handle 1221.

In some connections, referring to fig. 6, the drive mechanism 122 further includes a stationary shaft, the axis of which is non-collinear with the axis of the rotating shaft 1222; the driving handle 1221 is rotatably connected to the fixed shaft, and a driving shaft 12210 is disposed on a side of the driving handle 1221 facing the driving member 1223, the driving member 1223 is provided with a chute 1223B, and the driving handle 1221 can rotate around the fixed shaft to push the chute wall of the chute 1223B through the driving shaft 12210, so as to drive the driving member 1223.

The drive shaft 12210 and the slide slot 1223B are structures for cooperating with each other so that the drive handle 1221 drives the drive member 1223. The drive shaft 12210 may be fixedly or removably attached to the side of the drive handle 1221 facing the drive member 1223, which is not particularly limited in this application.

In this connection, when the axis of the fixed shaft is not collinear with the axis of the rotating shaft 1222, in order to adapt to the rotation conditions of the driving member 1223 and the driving handle 1221, the portion of the driving shaft 12210 driving the driving member 1223 needs to be changed, that is, the driving shaft 12210 needs to slide relative to the driving member 1223, so the sliding slot 1223B needs to be configured as a linear slot to meet the sliding requirement of the driving shaft 12210 relative to the driving member 1223.

In other connections, unlike the previous embodiments, the axis of the stationary shaft in the previous embodiments may be collinear with the axis of the rotary shaft 1222 and the chute 1223B may be configured as a slot that mates with the drive shaft 12210.

In this connection, the drive shaft 12210 does not need to slide in the slide groove 1223B, and the drive requirement can be satisfied.

It should be noted that, regardless of the form of the chute 1223B, the driving shaft 12210 may push the chute wall of the chute 1223B to make the driving member 1223 reciprocate clockwise and counterclockwise around the rotation shaft 1222, so that the driving member 1223 drives the opening and closing handle 112 through the driving block 1224 during rotation.

In still other implementations, the driving member 1223 is provided with a first abutment wall and a second abutment wall, the side of the driving handle 1221 facing the driving member 1223 is provided with a first abutment rod and a second abutment rod, and the first abutment wall and the second abutment wall are located between the first abutment rod and the second abutment rod.

In this connection, in the rotation process of the driving handle 1221, the first pushing wall may be pushed by the first pushing rod, and the second pushing wall may be pushed by the second pushing rod, so that the driving member 1223 makes a clockwise and counterclockwise reciprocating rotation around the rotation axis 1222, and the driving member 1223 drives the opening and closing handle 112 through the driving block 1224 in the rotation process.

On the basis of the foregoing embodiment, when the driving member 1223 is rotatably connected with the rotation shaft 1222, specifically, please continue to refer to fig. 6, the driving member 1223 is further provided with a connection hole 1223C adapted to the rotation shaft 1222; the rotation shaft 1222 is mounted to the connection hole 1223C to be in rotational engagement with the driving member 1223.

The connecting hole 1223C may be a through hole or a blind hole, which is not particularly limited in this application, as long as the driving member 1223 can be rotatably fitted with the rotation shaft 1222.
