The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

In one aspect of the embodiments of the present application, an operating mechanism is provided, which can be applied to a switching device, such as a single power supply product or a dual power supply product. As shown in fig. 1, the operating mechanism includes a housing 100, and a side operating shaft 110, a front operating member 130 and a transmission assembly disposed in the housing 100, wherein the housing 100 includes a top cover 101 and a bottom plate 102 opposite to each other, a side plate may be disposed between the top cover 101 and the bottom plate 102 to form an inner cavity, the top cover 101 may serve as a front surface of the housing 100, the bottom plate 102 may serve as a back surface of the housing 100, and the side plate may serve as a side surface of the housing 100.

Referring to fig. 1, a side operating shaft 110 is disposed on a side surface of the housing 100, the side operating shaft 110 may be connected to the linkage mechanism, and further, a closing operation of the switching device applied to the operating mechanism may be achieved by a movement of the side operating shaft 110, for example, when a product applied to the operating mechanism is a dual power supply change-over switch, the linkage mechanism may be driven by a movement of the side operating shaft 110 to achieve a closing operation and a opening operation of the common and standby power supplies. A positive operating member 130 is further disposed on the front surface of the casing 100, and the positive operating member 130 is in transmission connection with the side operating shaft 110 through a transmission assembly. Thus, the user can operate the front side. Through the movement of the positive operating part on the front side of the operating shell, the side operating shaft 110 is synchronously driven to perform switching-on action through the transmission component, so that the convenience of operation can be effectively improved in a mode that a user directly operates on the front side of the shell 100, and the space required by side operation does not need to be reserved in the cabinet because the user does not need to operate on the side of the shell 100, so that the utilization rate of the space in the cabinet can be effectively improved, and the miniaturization of the whole cabinet is facilitated.

In view of the intelligent and automatic requirements of the switching apparatus, an electric device may be disposed in the housing 100 of the switching apparatus, and the electric device is controlled by an electric signal to drive the side operation shaft 110 to close. As shown in fig. 2, the transmission assembly includes a translational long shaft 140, the translational long shaft 140 may be in driving connection with the side operating shaft 110, and the translational long shaft 140 may also be driven by an electric device (for example, the electric device is an electromagnet, and a tail end of the translational long shaft 140 may be engaged with the electromagnet, so that the translational long shaft 140 is driven by the electromagnet to translate relative to the housing 100, when necessary, so that the translational long shaft 140 translates relative to the housing 100, and then the translational long shaft 140 drives the side operating shaft 110 to rotate, so as to perform a closing action.

As shown in fig. 2, the positive operating element 130 is drivingly connected to the translational long shaft 140, so that in the manual operation mode, a user can drive the translational long shaft 140 to translate through the positive operating element 130, and further drive the lateral long shaft 110 to rotate through the translational long shaft 140 to perform a closing operation. Therefore, in the process of converting the side operation into the front operation, the translational long shaft 140 can be fully utilized, and the closing state of the positive operation piece 130 can be kept consistent with the closing state of the translational long shaft 140, namely the manual operation, the electric operation and the closing state are kept consistent.

In different embodiments, the positive operating element 130 may be slidably disposed on the housing 100, for example, a sliding rail is disposed on the housing 100, and correspondingly, the positive operating element 130 is slidably disposed on the sliding rail, so that when a user operates, the user can drive the positive operating element 130 to slide relative to the housing 100, so as to drive the translational long shaft 140 to translate, and simultaneously drive the lateral long shaft 110 to rotate by the translational long shaft 140 to perform a closing action.

Of course, the positive operation member 130 may also be rotatably disposed on the housing 100, so that the movement space required by the positive operation member 130 is smaller, which is beneficial to miniaturization of the product. Specifically, the method comprises the following steps: as shown in fig. 1 to 3, the front operating member 130 is rotatably disposed on the housing 100, the front operating member 130 is provided with a driving portion 170, the translational long shaft 140 is provided with a driven portion 180, the front operating member 130 is mutually matched and driven by the driving portion 170 and the driven portion 180 to establish a driving relationship with the translational long shaft 140, so that when a user performs front operation, the front operating member 130 can be driven to rotate first, the driving portion 170 is driven to rotate synchronously in the rotation process of the front operating member 130, the driving portion 170 drives the translational long shaft 140 to translate through the driven portion 180, and then the translational long shaft 140 drives the lateral operating shaft 110 to rotate, thereby implementing a closing action.

For example, when the operating mechanism is applied to a dual power supply product, as shown in fig. 4, the dual power supply product is in a double split position, which represents that both the main power supply (the common power supply) and the backup power supply are disconnected from the load. When manual switching-on (manual operation mode) is required, a user drives the positive operation piece 130 to rotate along the counterclockwise direction in the horizontal plane, so that the driving part 170 and the driven part 180 are matched to drive the translational long shaft 140 to translate from right to left, and in the process of translating the translational long shaft 140 from right to left, the lateral operation shaft 110 is correspondingly driven to rotate along the counterclockwise direction in the vertical plane until the switching-on position shown in fig. 5 is operated, and at this time, the main power supply or the standby power supply is connected with the load.

In another embodiment, the driving portion 170 has a driving groove, and correspondingly, when the driving portion 170 is assembled, the protrusion extends into the driving groove, so that when the driving portion 170 rotates along with the positive operating member 130, the protrusion is driven by the inner wall of the driving groove, and the translational long shaft 140 performs translational movement.

In order to improve the precision and smoothness of the driving, in the embodiment where the driving portion 170 has the driving groove for receiving the protrusion, the driving groove may be configured as a U-shaped groove, so that the conversion between the rotation of the positive operation member 130 and the translation of the translation long shaft 140 can be realized through the cooperation of the U-shaped groove and the protrusion, and at the same time, the motion difference between the rotation and the translation can be effectively relieved through the kidney-shaped hole 171.
