[0026] Embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0027] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one 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.

[0028] As described above, the opening and closing handle of an electrical switch can be driven, thereby causing the moving contact assembly to move toward or away from the stationary contact assembly via a transmission mechanism within the switch, thus realizing the opening and closing process. However, when the installation method of the electrical switch is changed, the operating direction of the opening and closing handle is changed accordingly. For example, when the electrical switch is changed from rear-mounted to side-mounted, the operating direction of the opening and closing handle does not conform to user habits and ergonomic design, increasing the difficulty of operation.

[0029] Embodiments of this disclosure provide an operating mechanism and switch assembly for an electrical switch, to at least partially solve the aforementioned problems. In the following, in conjunction with... Figures 1 to 3 The principles of this disclosure are described.

[0030] Figure 1 A schematic diagram of the structure of a switch assembly according to some embodiments of the present disclosure is shown. Figure 2 A partial structural schematic diagram of a switch assembly according to some embodiments of the present disclosure is shown, wherein the switch assembly illustrates an electrical switch 200 and an operating mechanism 100 coupled to the electrical switch 200. For example... Figure 1 and Figure 2 As shown, the operating mechanism 100 described herein includes a support 1, an operating member 2, a first transmission member 3, a second transmission member 4, and a moving member 5.

[0031] refer to Figure 1 and Figure 2 In some embodiments, the operating member 2 is rotatably coupled to the support 1, and the operating member 2 may be disposed on the outside of the support 1. An operator is adapted to drive the operating member 2 to rotate relative to the support 1. A first transmission member 3 is rotatably coupled to the support 1 and is also coupled to the operating member 2. The first transmission member 3 may be disposed on the outside or inside of the support 1. Thus, when the operating member 2 is driven, the first transmission member 3 can rotate along a first direction following the operating member 2. A second transmission member 4 is rotatably coupled to the support 1 and engages with the first transmission member 3. The second transmission member 4 may be disposed on the outside or inside of the support 1. Thus, when the first transmission member 3 rotates along the first direction, the second transmission member 4 rotates along a second direction under the drive of the first transmission member 3. The second direction is different from the first direction.

[0032] Continue to refer to Figure 2In some embodiments, the second transmission member 4 includes a drive portion 41. The moving member 5 is movably coupled to the bracket 1. The moving member 5 includes a first receiving portion 51 and a second receiving portion 52. At least a portion of the drive portion 41 is disposed within the first receiving portion 51. Thus, when the second transmission member 4 rotates along a second direction, the second transmission member 4 is adapted to drive the moving member 5 to move relative to the bracket 1 via the drive portion 41. The second receiving portion 52 is adapted to receive the opening / closing handle 203 of the electrical switch 200, that is, at least a portion of the opening / closing handle 203 is disposed within the second receiving portion 52. Thus, when the moving member 5 moves relative to the bracket 1, the moving member 5 is adapted to drive the opening / closing handle 203 and cause the opening / closing handle 203 to rotate.

[0033] According to the operating mechanism 100 implemented in this disclosure, the operating direction can be changed by the cooperation of the operating member 2, the first transmission member 3 and the second transmission member 4, and the opening and closing handle 203 of the electrical switch 200 can be driven by the moving member 5 to realize the opening and closing operation. In this way, when the installation method of the electrical switch 200 is changed, the operating member 2 is adapted to be driven in the driving direction of the opening and closing handle 203 before the change, thereby improving the convenience of operation.

[0034] Figure 3 A cross-sectional view of an operating mechanism 100 according to some embodiments of the present disclosure is shown. For example... Figure 2 and Figure 3 As shown, in some embodiments, the movable member 5 may be disposed within the bracket 1 and may include a main body 53 and at least one slide groove 54. At least one slide groove 54 may be disposed on the main body 53. Correspondingly, the bracket 1 may include at least one guide shaft 11, which may be located inside the bracket 1. At least one slide groove 54 may be coupled to at least one guide shaft 11 to allow the movable member 5 to move along at least one guide shaft 11. It should be understood that in other embodiments, at least one sliding hole may also be provided on the main body 53. At least one sliding hole may be coupled to at least one guide shaft 11 to allow the movable member 5 to move along at least one guide shaft 11.

[0035] refer to Figure 2 and Figure 3 In some embodiments, at least one groove 54 includes a pair of grooves 54. Correspondingly, at least one guide shaft 11 may include a pair of guide shafts 11. The pair of guide shafts 11 extend in the same direction. Each pair of grooves 54 is coupled to a corresponding guide shaft 11. In this way, it is suitable to improve the stability of the moving member 5 during movement.

[0036] It should be noted that the figures, values, numbers, etc., mentioned above and elsewhere in this disclosure are exemplary and are not intended to limit the scope of this disclosure in any way. Any other suitable figures, values, or numbers are possible. For example, depending on the specific application scenario and requirements, at least one groove 54 and at least one guide shaft 11 may include more or fewer quantities.

[0037] refer to Figure 2 In some embodiments, the first receiving portion 51 may include a mating groove. The mating groove includes a first pair of mating surfaces 511 disposed opposite each other along the moving direction X of the moving member 5. The first pair of mating surfaces 511 may be spaced apart from each other. The driving portion 41 is located between the first pair of mating surfaces 511 and is adapted to abut against the first pair of mating surfaces 511. In this way, the driving portion 41 is adapted to drive the moving member 5 to move or be driven by the moving member 5 via the first pair of mating surfaces 511.

[0038] It should be understood that in other embodiments, the first receiving portion 51 may also include a mating hole. However, when the driving portion 41 is located within the mating hole, at least one guide shaft 11 needs to be spaced apart from the driving portion 41 to avoid the at least one guide shaft 11 interfering with the rotation of the driving portion 41.

[0039] During the switching process between the open and closed positions, the electrical switch 200 passes through a dead position, wherein the drive actuating element 2 is adapted to switch the electrical switch 200 from one of the open or closed positions to the dead position. When the electrical switch 200 reaches the dead position, a spring (not shown) of the electrical switch 200 is pressed or stretched and is adapted to store energy. The spring is coupled to a transmission mechanism (not shown), and the transmission mechanism is coupled to the open / close handle 203. Thus, the spring is adapted to release energy and drive the open / close handle 203 and the transmission mechanism to rotate rapidly. The transmission mechanism may be coupled to a moving contact assembly to switch the electrical switch 200 toward the other of the open and closed positions.

[0040] refer to Figure 2 In some embodiments, the drive unit 41 may include a drive bearing, which can reduce the frictional force during its interaction with the moving member 5. The diameter of the outer ring portion of the drive bearing may be smaller than the distance between the first pair of mating surfaces 511, that is, the drive unit 41 and the moving member 5 are spaced apart along the movement direction X.

[0041] It is understood that during the process of switching the electrical switch 200 from one of the open or closed positions to the dead position, the drive unit 41 is adapted to abut against one of the mating surfaces of the first pair of mating surfaces 511, thereby driving the moving member 5 and the opening / closing handle 203. However, after the electrical switch 200 switches to the dead position, the spring releases energy and drives the opening / closing handle 203 and the transmission mechanism, so that the electrical switch 200 quickly switches to the other position between the open and closed positions. During this process, the opening / closing handle 203 drives the moving member 5 to move. At this time, the other mating surface of the first pair of mating surfaces 511 moves to abut against the drive unit 41 to drive the second transmission member 4. The above-mentioned spacing effectively prevents the drive unit 41 from being confined within the first receiving portion 51 and unable to move, thereby avoiding the problem of jamming.

[0042] refer to Figures 1 to 3 In some embodiments, the second transmission member 4 may further include a transmission portion 42 and a mating portion 43. The mating portion 43 is coupled to the transmission portion 42 and is located within the bracket 1. The mating portion 43 may be fixedly connected to the transmission portion 42, for example, by being integrally formed with the transmission portion 42 or by fastening means such as screws. At least a portion of the transmission portion 42 is disposed within the bracket 1 and may engage with the first transmission member 3 to transmit torque. A bearing may be fitted on the shaft of the transmission portion 42, and the outer ring portion of the bearing may be coupled to the bracket 1 to reduce friction when the transmission portion 42 rotates relative to the bracket 1. Furthermore, a drive portion 41 may be disposed on the mating portion 43. In this way, the second transmission member 4 is adapted to transmit force and torque between the first transmission member 3 and the moving member 5.

[0043] refer to Figures 1 to 3 In some embodiments, the first transmission member 3 may be fixedly connected to the operating member 2, for example, by integrally forming the first transmission member 3 with the operating member 2 or by fastening components such as screws. Furthermore, a bearing may be sleeved on the shaft of the first transmission member 3, and the outer ring portion of the bearing may be coupled to the bracket 1 to reduce friction when the first transmission member 3 rotates relative to the bracket 1.

[0044] The first transmission member 3 and the transmission part 42 according to embodiments of this disclosure can be various types of transmission components currently known or available in the future, as long as they are suitable for changing the direction of rotation; embodiments of this disclosure do not limit this. For example, refer to... Figures 1 to 3 In some embodiments, the first transmission member 3 may include a first bevel gear. Correspondingly, the transmission part 42 includes a second bevel gear meshing with the first bevel gear. In this way, when the first bevel gear and the second bevel gear mesh, it is suitable to change the direction of rotation. In other embodiments, the first transmission member 3 may also include a worm gear. Correspondingly, the transmission part 42 may also include a worm gear meshing with the worm gear.

[0045] refer to Figures 1 to 3 In some embodiments, the shaft of the first bevel gear may intersect the shaft of the second bevel gear perpendicularly. Thus, the first direction may be perpendicular to the second direction. In other embodiments, the shafts of the first and second bevel gears may also be arranged at acute or obtuse angles to each other. The embodiments disclosed herein are not limited in this respect.

[0046] refer to Figure 1 and Figure 2 In some embodiments, the second receiving portion 52 may include a mating hole. At least a portion of the opening / closing handle 203 may be disposed within the mating hole. At least one guide shaft 11 needs to be spaced apart from the opening / closing handle 203 to avoid interference with the rotation of the opening / closing handle 203. In this way, the moving member 5 is adapted to drive or be driven by the opening / closing handle 203 to realize the opening / closing operation. It should be understood that in other embodiments, the second receiving portion 52 may also include a mating groove, within which at least a portion of the opening / closing handle 203 may be disposed.

[0047] refer to Figure 1 and Figure 2 In some embodiments, the mating hole may include a second pair of mating surfaces 521 disposed opposite each other along the moving direction X of the moving member 5. The second pair of mating surfaces 521 may be spaced apart from each other. The opening and closing handle 203 is located between the second pair of mating surfaces 521 and is adapted to abut against the second pair of mating surfaces 521. In this way, the moving member 5 is adapted to drive the opening and closing handle 203 or be driven by the opening and closing handle 203 through the second pair of mating surfaces 521, thereby realizing the opening and closing operation.

[0048] Continue to refer to Figure 2 Furthermore, along the moving direction X of the moving member 5, the distance between the second pair of mating surfaces 521 can be greater than the size of the opening / closing handle 203. It should be understood that the above-mentioned distance effectively prevents the opening / closing handle 203 from being confined within the mating hole and unable to move, thereby avoiding the problem of jamming.

[0049] In the following text, we will combine Figure 2 and Figure 3 This describes the working process of the operating mechanism 100 driving the electrical switch 200 from the open position to the closed position. It is understood that the working process of the operating mechanism 100 driving the electrical switch 200 from the closed position to the open position is the same or similar, and this disclosure will not elaborate on it.

[0050] refer to Figure 2 and Figure 3The operating member 2 is rotated in the direction that drives the electrical switch 200 to switch to the closed position. The operating member 2 drives the first transmission member 3 to rotate. The first transmission member 3 drives the second transmission member 4 to rotate. During the rotation of the second transmission member 4, the driving part 41 contacts one of the mating surfaces of the first pair of mating surfaces 511 and drives the moving member 5 to move along the guide shaft 11. During the movement of the moving member 5, one of the mating surfaces of the second pair of mating surfaces 521 contacts the opening / closing handle 203 and drives the opening / closing handle 203 to rotate the electrical switch 200 to the closed position. During the switching process, the electrical switch 200 is adapted to rotate to the dead position between the closed position and the open position.

[0051] Continue to refer to Figure 2 and Figure 3 When the electrical switch 200 reaches its dead position, the spring of the electrical switch 200 is pressed or stretched, storing energy. The spring then releases this energy and drives the opening / closing handle 203 and the transmission mechanism to rotate rapidly. Because the opening / closing handle 203 rotates very quickly, it rotates to a position where it contacts another mating surface in the second pair of mating surfaces 521. At this point, under the action of the released spring energy, the opening / closing handle 203 drives the moving member 5 to continue moving along the guide shaft 11, without requiring manual operation of the operating member 2.

[0052] Continue to refer to Figure 2 and Figure 3 As the moving part 5 continues to move along the guide shaft 11, the other mating surface of the first pair of mating surfaces 511 moves to a position where it contacts the driving part 41, and drives the second transmission part 4 to rotate. The second transmission part 4 drives the first transmission part 3 to rotate. The first transmission part 3 drives the operating part 2 to rotate. Finally, the electrical switch 200 switches to the open position.

[0053] Return to reference Figure 1 and Figure 2 Embodiments of this disclosure also provide a switch assembly, which includes an electrical switch 200 and an operating mechanism 100 according to any of the first aspects of this disclosure. The electrical switch 200 may include a base 201, a top cover 202 disposed on the base 201, and a closing / opening handle 203 passing through the top cover 202. The operating mechanism 100 may be coupled to a side of the top cover 202 opposite to the base 201, and a bracket 1 may be disposed on the side of the top cover 202 opposite to the base 201. The closing / opening handle 203 may be disposed within a second receiving portion 52.

[0054] Continue to refer to Figure 1In some embodiments, the base 201 includes a first pair of side plates 2011 disposed opposite to each other. The first pair of side plates 2011 can be connected to the side of the base 201 opposite to the top cover 202. The top cover 202 includes a second pair of side plates 2021 disposed opposite to each other. The second pair of side plates 2021 can be connected to the side of the top cover 202 opposite to the base 201. The first pair of side plates 2011 can be disposed on the same side as the second pair of side plates 2021. Correspondingly, the electrical switch 200 may also include a plurality of fasteners 204. At least one of the plurality of fasteners 204 can pass through the first pair of side plates 2011 and is fixed to a connecting carrier (not shown). The remaining fasteners 204, excluding the at least one fastener 204, can pass through the second pair of side plates 2021 and are fixed to the connecting carrier. In this way, it is suitable to realize the side mounting of the electrical switch 200.

[0055] The fastener 204 according to embodiments of this disclosure can be of various types of fastening components currently known or available in the future, and the embodiments of this disclosure are not limited thereto. For example, in some embodiments, the fastener 204 can be a fastening bolt.

[0056] Continue to refer to Figure 1 In some embodiments, the electrical switch 200 may further include a plurality of locking elements 205, which may include, for example, nuts. The plurality of locking elements 205 may be disposed on the side of the connecting carrier opposite to the electrical switch 200 and are adapted to be fixedly connected with a plurality of fasteners 204. It is understood that the threaded engagement of the plurality of locking elements 205 with the plurality of fasteners 204 is suitable for securely fixing the electrical switch 200 to the connecting carrier.

[0057] The operating mechanism according to embodiments of this disclosure can be applied to electrical switches such as circuit breakers to at least partially solve the above-mentioned problems. It should be understood that the operating mechanism according to embodiments of this disclosure can also be applied to other electrical components, and embodiments of this disclosure do not limit this application.

[0058] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
