[0024] Embodiments of the present disclosure will be described in more detail with reference to the drawings. Although certain embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be interpreted as being limited to the embodiments set forth herein, but rather, the embodiments are provided so that the present disclosure can be more thoroughly and completely understood. It is understood that the drawings and embodiments of the present disclosure are for exemplary purposes only and are not intended to limit the scope of protection of the present disclosure.

[0025] In the description of embodiments of the present disclosure, the term "comprising" and its conjugations are to be understood to be open-ended, i.e., not limiting to only comprise what follows the term. The term "based on" is to be understood as "based, at least in part, on". The term "one embodiment" or "an embodiment" are to be understood not to mean one and the only embodiment and that there is a plurality of embodiments. The term "some embodiments" is to be understood not to mean some but not all embodiments and that there is a plurality of embodiments. The terms "first", "second" and the like can refer to different or same objects. Other explicit or implicit definitions can also be included below.

[0026] The existing remote control auxiliary device has problems in torque transmission stability, force balance and the like. Meanwhile, during the switching process of the operating handle of the remote control auxiliary device, especially when the operating handle is in an inclined state under the action of external force, the torque during transmission will be significantly increased, thereby affecting the stability of the transmission system. In addition, due to the imperfect transmission structure of the existing remote control auxiliary device, stress concentration on the contact surface, reduced transmission efficiency, and even the service life of the remote control auxiliary device are affected.

[0027] In order to solve or at least partially solve the above-mentioned problems or other potential problems of the switch device of the conventional scheme, embodiments of the present disclosure provide a drive assembly for a switch device and a switch device scheme. According to the scheme of the embodiments of the present disclosure, the drive assembly includes a drive member. The drive member is arranged in a housing of the switch device. Further, the drive assembly also includes an operating handle. The operating handle includes a rotating part arranged in the housing and is operable to rotate about a rotation axis, the rotating part having a mounting groove and a waist-shaped hole. Further, the drive assembly also includes a gear transmission assembly. The gear transmission assembly is coupled between the drive member and the operating handle and is adapted to transmit power of the drive member to the operating handle. The gear transmission assembly includes a final-stage gear and a transmission rod. The final-stage gear is arranged in the mounting groove and is adapted to rotate about the rotation axis under the drive of the drive member. The transmission rod is coupled on the final-stage gear and is arranged in the waist-shaped hole, the transmission rod being adapted to rotate with the final-stage gear to push the rotating part to rotate about the rotation axis via an end wall of the waist-shaped hole in the extension direction of the waist-shaped hole, so as to switch the operating handle between an open position and a closed position.

[0028] In this way, the drive assembly, through the cooperation of the final-stage gear and the transmission rod with the operating handle, enables the power of the drive member to be reliably transmitted to the operating handle. The final-stage gear is arranged in the mounting groove and rotates about the rotation axis under the drive of the drive member. The transmission rod is coupled with the final-stage gear and arranged in the waist-shaped hole, so that when the final-stage gear rotates, the transmission rod can move along the end wall of the waist-shaped hole, thereby pushing the rotating part to rotate about the rotation axis. This arrangement ensures that the operating handle is switched between the open position and the closed position, effectively balances the force, reduces the deviation and additional stress concentration caused by unilateral force, and improves the reliability of the switch device.

[0029] The following will describe an example structure of the switch device 100 in conjunction with Figures 1 to 8 The switch device 100 according to the embodiments of the present disclosure can include a circuit breaker. Hereinafter, the concept of the present disclosure will be described taking the circuit breaker as an example, and it should be understood that the following description is also similar for the case where the switch device 100 is other switches, which will not be described separately hereinafter.

[0030] The switch device 100 according to the embodiments of the present disclosure comprises a switch piece 110 and a driving assembly 120, wherein an operating handle 122 of the driving assembly 120 is coupled with the switch piece 110 and is adapted to drive the switch piece 110 to switch between the open position and the closed position through the operating handle 122.

[0031] Further, the switch piece 110 comprises a switch element for connecting a circuit, which can control the on-off of the circuit in different working states of the switch device 100. When the switch piece 110 is in the closed position, the circuit is connected and the current can flow normally; when the switch piece 110 is in the open position, the circuit is disconnected and the current is cut off.

[0032] The operating handle 122 in the driving assembly 120 is a component for controlling the state of the switch piece 110, which is coupled with the switch piece 110 through a mechanical structure. The operating handle 122 can ensure that the switch piece 110 is smoothly and accurately moved from the open position to the closed position or from the closed position to the open position when manually or remotely operated. The driving assembly 120 can realize remote or automatic control of the switch device 100. Meanwhile, the driving assembly 120 is detachably connected to the circuit breaker.

[0033] The specific structure of the driving assembly 120 will be described below in combination with Figures 1 to 8 FIG. 1. Figures 1 to 8 As shown in FIG. 1, the driving assembly 120 for the switch device 100 according to the embodiments of the present disclosure generally comprises a driving piece 121, an operating handle 122 and a gear transmission assembly, which cooperate with each other to ensure that the operating handle 122 can be stably and reliably switched between the open position and the closed position.

[0034] Specifically, the driving piece 121 is arranged in the housing of the switch device 100 as a power source of the driving assembly 120. The driving piece 121 can adopt a motor, a solenoid or other suitable electric or electromagnetic driving mechanism for switch driving to provide stable power output so as to drive the operating handle 122 to switch.

[0035] The operating handle 122 is used for manually or automatically controlling the opening and closing of the switch device 100. The operating handle 122 comprises a rotating part 1221. The rotating part 1221 is arranged in the housing and is operable to rotate around a preset rotation axis. Meanwhile, the rotating part 1221 is provided with a mounting groove and a waist-shaped hole for coupling with the gear transmission assembly and realizing the driving function.

[0036] The gear transmission assembly is used for power transmission, connecting the driving member 121 and the operating handle 122 to transmit the power of the driving member 121 to the operating handle 122, ensuring reliable movement thereof. The gear transmission assembly comprises a final gear 1231 and a transmission rod 1232. The final gear 1231 is arranged in the mounting groove of the operating handle 122 and rotates around the rotation axis under the action of the driving member 121. The rotation of the final gear 1231 can drive the transmission rod 1232 to move, and the transmission rod 1232 is arranged in the waist-shaped hole, thereby driving the rotating part 1221 to rotate. In some embodiments, the transmission rod 1232 is detachably connected to the final gear 1231 to form an insertion structure.

[0037] When the driving member 121 is started, the final gear 1231 rotates, thereby driving the transmission rod 1232 to move along the length direction of the waist-shaped hole. When the transmission rod 1232 reaches the end wall of the waist-shaped hole, a pushing force is generated to act on the rotating part 1221, so that the operating handle 122 rotates around the rotation axis, thereby realizing the switching of the operating handle 122 between the open position and the closed position. In this way, the movement of the operating handle 122 can be ensured to be smooth, and the overload problem caused by rigid connection can be avoided, improving the reliability and durability of the transmission.

[0038] As shown in Figure 2 and Figure 4 In some embodiments, the operating handle 122 further comprises an operating rod 1224 for manually or assistingly driving the switching function, improving the convenience and reliability of the operation.

[0039] Specifically, the operating rod 1224 is arranged outside the housing, and the fixed end thereof is coupled with the rotating part 1221. This structure ensures the integrated movement of the operating rod 1224 and the rotating part 1221, so that the driving assembly 120 can control the rotation of the operating rod 1224 through the rotating part 1221, thereby realizing the switching of the switch device 100 between the open position and the closed position.

[0040] In some embodiments, the user can exert an external force on the operating rod 1224 of the operating handle 122 to rotate the switch member 110 around the rotation axis, thereby changing the state of the switch device 100, such as the closed or open state. Since the operating rod 1224 is located outside the housing, it can adopt an ergonomic design, such as having a shape conforming to the gripping habit or adding a non-slip coating, to improve the comfort and efficiency of manual operation.

[0041] As shown in Figure 2 and Figure 6As shown, in some embodiments, the operating handle 122 further comprises a fixed shaft 1225 and a movable block 1226, which are designed to improve the motion characteristics of the operating lever 1224, reduce the instability caused by the change of moment of force during operation, and improve the durability and reliability of the driving assembly 120.

[0042] Specifically, the fixed shaft 1225 is coupled to the operating lever 1224 and arranged at a position away from the fixed end of the operating lever 1224. The fixed shaft 1225 provides a rotation fulcrum for the movable block 1226, so that the movable block 1226 can be adjusted adaptively with the motion of the operating lever 1224.

[0043] Further, the movable block 1226 is coupled to the inside of the operating lever 1224 via the fixed shaft 1225, and the movable block 1226 extends a predetermined distance along the extension direction of the operating lever 1224. This connection mode can make the movable block 1226 deflect on the operating lever 1224, rotate freely relative to the operating lever 1224, and abut against the inner wall of the operating lever 1224 in certain cases. Specifically, when the operating lever 1224 is deflected in a certain direction by external force operation during rotation, the movable block 1226 will rotate relatively due to inertia or force change, and always maintain the original posture to drive the switch piece 110, thereby avoiding additional torsional force during operation caused by the change of moment of force, and improving the smoothness and reliability of operation. That is, the movable block 1226 can dynamically adjust according to the deflection of the operating lever 1224, so as to adapt to different operating environments, reduce wear caused by long-term use, and improve the durability of the driving assembly 120.

[0044] In some embodiments, the rotating part 1221 comprises a pair of support parts. The pair of support parts are located on both sides of the mounting groove in the extension direction of the rotation axis. The pair of support parts are used to support and fix the final gear 1231, so as to ensure that the final gear 1231 can remain stable during rotation, avoid deflection or deformation of the gear caused by external force or wear, and improve the transmission efficiency and stability of the driving assembly 120.

[0045] Further, the final gear 1231 is arranged between the pair of support parts. The final gear 1231 cooperates with the pair of support parts to ensure that the power can be efficiently and reliably transmitted to the operating handle 122 under the driving of the driving piece 121.

[0046] The waist-shaped hole is arranged on a pair of support portions, so that the transmission rod 1232 can interact with the rotating portion 1221 through the waist-shaped hole, ensuring the stability of the movement of the transmission rod during transmission. In other words, the transmission rod 1232 forms a double-side cross-connection structure with the pair of support portions, which can effectively balance the stress through the double-side cross-connection structure, reduce the deviation and additional stress concentration caused by unilateral stress. In addition, by increasing the span of the stress point, the driving assembly 120 has higher stability when bearing external force, avoiding shaking and energy loss during transmission.

[0047] Further, the waist-shaped hole provides a preset free travel space for the transmission rod 1232, which can freely move without being limited during operation. It should be noted that when the operating handle 122 reaches the closed position, the transmission rod 1232 needs to return to the preset position, which enables the operating handle 122 to perform automatic opening operation at any time without being affected by the transmission rod 1232 when the switch device 100 provides reliable protection against electrical faults (such as short circuit, overload, arc fault, etc.).

[0048] As shown in FIG. 1, Figure 3 In some embodiments, a worm gear 1211 is arranged on the output shaft of the driving member 121. The worm gear 1211 can achieve a large ratio of speed reduction transmission in a small space. Through the arrangement of the worm gear 1211, the high-speed rotary motion output by the driving member 121 is converted into a lower speed and high torque rotary output, which can meet the torque demand in the operation process of the switch device 100.

[0049] The driving assembly 120 further comprises a multi-stage reduction gear 1233. The multi-stage reduction gear 1233 is engaged between the worm gear 1211 and the final gear 1231. The multi-stage reduction gear 1233 can further reduce the rotating speed during power transmission, while increasing the output torque, so that the final gear 1231 can stably operate at an appropriate rotating speed. Such multi-stage reduction gear 1233 can avoid excessive wear or efficiency loss of single-stage reduction gear when bearing large load, thereby ensuring the reliability and durability of the driving assembly 120 during long-term operation.

[0050] In some embodiments, the multi-stage reduction gear 1233 comprises a plurality of gear sets of engagement levels, each gear set gradually reduces the speed of the input high-speed rotation to a lower output rotating speed through different gear ratios. Each gear set of level comprises two gears meshing with each other, one being a driving gear and the other being a driven gear. The first level driving gear is driven by the worm gear 1211, and the driven gear is meshed with the next level driving gear, and so on, until the last level gear in the multi-stage reduction gear 1233 is connected with the final gear 1231. For example, the multi-stage reduction gear 1233 comprises three gear sets of engagement levels.

[0051] In operation, the worm gear 1211 receives high-speed rotation from the output shaft of the drive member 121 and gradually reduces the rotation through the multi-stage reduction gear 1233. In the first stage, the worm gear 1211 engages with the first reduction gear, which drives the second reduction gear to rotate. Each reduction gear set gradually reduces the speed through different gear ratios until the last stage gear transmits power to the final gear 1231, achieving lower speed output. This gradual reduction process effectively reduces impact force during transmission, reduces the load of the gear system, and ensures that the operating handle 122 can smoothly drive the switch member 110 to switch positions.

[0052] As shown in some embodiments, the drive assembly 120 further includes a circuit board 125 arranged inside the housing and electrically connected with the drive member 121. Figure 8

[0053] Further, the circuit board 125 can be used to receive signals from an external control system and transmit signals to the drive member 121. The circuit board 125 can control the start-stop, speed adjustment, torque output, and other functions of the drive member 121, ensuring that the drive member 121 can operate efficiently and stably according to the predetermined working mode.

[0054] In some embodiments, various sensors and monitoring modules can be integrated on the circuit board 125, such as temperature sensors, current sensors, or position sensors, etc., for real-time monitoring of the working state of the drive member 121. The feedback information of these sensors can be processed by the circuit board 125 and used to adjust the working state of the drive member 121 to prevent overloading, overheating, and other problems, improving the safety and reliability of the system. At the same time, the circuit board 125 can also support communication with external devices, such as data exchange with remote control systems, PLCs (Programmable Logic Controllers), or automation control systems through communication protocols, further realizing remote monitoring and control.

[0055] The electrical connection of the circuit board 125 can be achieved through connectors or wires to ensure stable signal transmission. The circuit board 125 can also be equipped with a power management module to provide stable power supply for the drive member 121, ensuring reliable operation of the drive assembly 120 in various working environments. For example, the circuit board 125 can use a PCB (Printed Circuit Board) circuit board.

[0056] As shown in some embodiments, the drive assembly 120 further includes a circuit board 125 arranged inside the housing and electrically connected with the drive member 121. Figure 5 、 Figure 7 and Figure 8 ​As shown, in some embodiments, the driving assembly 120 further comprises a first sensor 1241. The first sensor 1241 is arranged on one side of the transmission rod 1232 adjacent to the circuit board 125. The first sensor 1241 is used to sense the rotational position of the final gear 1231, and to monitor the movement state of the final gear 1231 in real time.

[0057] To cooperate with the sensing function of the first sensor 1241, the driving assembly 120 further comprises a first magnet 1251. The first magnet 1251 is arranged on the circuit board 125 at a position corresponding to the first sensor 1241, to form a magnetic field interaction with the first sensor 1241. The first magnet 1251 is used to provide a stable magnetic field signal, so that the first sensor 1241 can sense the rotational position of the final gear 1231 under the change of the magnetic field.

[0058] The cooperation of the first sensor 1241 and the first magnet 1251 can provide real-time feedback of the specific position data of the final gear 1231 to the circuit board 125. After receiving these data, the circuit board 125 can adjust the control instructions of the driving member 121, to ensure the accurate operation of the switch device 100.

[0059] When the final gear 1231 drives the operating handle 122 to reach the closed position via the transmission rod 1232, the first sensor 1241 is misaligned with the first magnet 1251, at which time the driving member 121 needs to rotate in the direction of opening and drive the final gear 1231 back to the preset position. The transmission rod 1232 can move in the free stroke of the waist-shaped hole of the operating handle 122, so that the first sensor 1241 is aligned with the first magnet 1251, while the circuit board 125 sends a stop signal to the driving member 121, to avoid over operation or damage to the equipment. This ensures that when the switch device 100 provides reliable protection against electrical faults (such as short circuit, overload, arc fault, etc.), the operating handle 122 can be automatically opened at any time without being affected by the transmission rod 1232.

[0060] In some embodiments, the driving assembly 120 further comprises a second sensor 1242. The second sensor 1242 is arranged on one side of the rotating part 1221 adjacent to the circuit board 125, and is adapted to sense the rotational position of the operating handle 122. Through the arrangement of the second sensor 1242, the movement state of the operating handle 122 can be monitored in real time. When the operating handle 122 rotates, the second sensor 1242 will provide a corresponding signal according to the change of its position, which is fed back to the circuit board 125, so that the circuit board 125 can make corresponding control or adjustment. For example, the first sensor 1241 and the second sensor 1242 can be Hall sensors.

[0061] To cooperate with the second sensor 1242, the driving assembly 120 further comprises a second magnet 1252 and a third magnet 1253, which are arranged on the circuit board 125 at positions corresponding to the preset positions of the second sensor 1242. The second magnet 1252 is arranged at a position on the circuit board 125 corresponding to the position of the second sensor 1242 in the open state, and the third magnet 1253 is arranged at a position on the circuit board 125 corresponding to the position of the second sensor 1242 in the closed state. The arrangement of the two magnets enables the second sensor 1242 to sense the rotational position of the operating handle 122 and identify the state of the switch device 100 according to the change of the magnetic field.

[0062] Specifically, when the operating handle 122 is in the open state, the second sensor 1242 detects the magnetic field signal corresponding to the second magnet 1252; and when the operating handle 122 is rotated to the closed state, the second sensor 1242 senses the magnetic field signal generated by the third magnet 1253. In this way, the circuit board 125 can accurately determine the current position of the operating handle 122, thereby accurately controlling the working state of the driving member 121 and ensuring the smooth and reliable operation of the switch device 100.

[0063] The above has described the implementations of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed implementations. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described implementations.
