[0030] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] The utility model provides a state indication structure of an intelligent switch, such as Figures 1 to 5 As shown, the switch comprises a housing 1, at least one cam link mechanism 4 rotatably disposed in the housing 1, and a rotating rod 5. The housing 1 is the external structure of the entire switch, and is used to fix and support the internal components of the switch. The upper end of the cam link mechanism 4 is connected to the drive mechanism 2 of the switch, and the lower end is connected to the circuit 3 of the switch. When the drive mechanism 2 works, it drives the cam link mechanism 4 to rotate, thereby connecting or disconnecting the circuit 3.

[0032] The rotating rod 5 is connected to the cam-link mechanism 4 as a status indicating component. When the cam-link mechanism 4 rotates, it drives the rotating rod 5 to rotate together. An indicating piece 51 is fixed to the top of the rotating rod 5, and an indicating window 11 is provided on the housing 1. When the driving mechanism 2 drives the cam-link mechanism 4 to rotate to connect the circuit 3, the cam-link mechanism 4 will simultaneously drive the rotating rod 5 to rotate, so that the indicating piece 51 is exposed from the indicating window 11, which indicates that the switch circuit 3 is in a connected state; conversely, when the indicating piece 51 rotates to another position, it will be hidden in the housing 1 and cannot be seen from the indicating window 11. The operator can judge whether the switch circuit 3 is in a connected or disconnected state through the indicating window 11.

[0033] In this embodiment, if Figure 2 and Figure 5 As shown, the cam-link mechanism 4 is mainly composed of the following components, including a cam 41, a connecting rod 42, a shaft rod 44 and a connecting seat 45. The cam 41 and the shaft rod 44 are both rotatably arranged in the housing 1, and the cam 41 is connected to the driving mechanism 2 and the circuit 3. The connecting seat 45 is movably sleeved on the outer periphery of the shaft rod 44 and connected to the rotating rod 5. The connecting seat 45 is provided with a limiting groove 451 on one side facing the cam 41. One end of the connecting rod 42 is pivotally connected to the cam 41, and the other end of the connecting rod 42 is provided with a clearance groove 421. The other end of the connecting rod 42 passes through the limiting groove 451 and enters the interior of the connecting seat 45, and the clearance groove 421 is sleeved with the shaft rod 44.

[0034] When the driving mechanism 2 drives the cam 41 to rotate, the cam 41 drives the connecting rod 42 to rotate. Since the other end of the connecting rod 42 is connected to the connecting seat 45, and the connecting seat 45 is movably sleeved on the shaft 44, when the connecting rod 42 rotates, the connecting seat 45 will deflect around the shaft 44, and the connecting rod 42 drives the connecting seat 45 to deflect. This deflection movement is transmitted to the rotating rod 5 through the connecting seat 45, thereby driving the rotating rod 5 to rotate. The design of the clearance slot 421 of the connecting rod 42 and the shaft 44 sleeve allows the connecting rod 42 to perform limited sliding movement on the shaft 44, which helps to ensure that the connecting rod 42 can move smoothly under the push of the cam 41.

[0035] like Figure 5 As shown, the connecting rod 42 is sleeved with a return spring 43, and the two ends of the return spring 43 are respectively in contact with the cam 41 and the connecting seat 45. When the driving mechanism 2 drives the cam 41 to rotate and causes the cam 41 to deflect, the cam 41 causes the return spring 43 to deform. When the cam 41 stops rotating or rotates in the reverse direction, the return spring 43 releases its stored energy and tries to return to its original length. This restoring force pushes the connecting rod 42 and the connecting seat 45 back to their initial positions, ensuring that they can accurately cooperate with the cam 41 when the cam 41 rotates next time.

[0036] The connection structure between the connecting seat 45 and the rotating rod 5 is as follows: Figure 5 , an opening slot 452 is provided on the side of the connection seat 45 away from the cam 41, and a toggle block 52 is provided at a position corresponding to the opening slot 452 of the rotating rod 5. The shape and size of the opening slot 452 are adapted to the wave block, allowing the toggle block 52 to be embedded in the opening slot 452, thereby realizing the connection between the connection seat 45 and the rotating rod 5. When the connection seat 45 deflects under the drive of the cam 41, since the toggle block 52 is embedded in the opening slot 452, the deflection movement of the connection seat 45 will be directly transmitted to the rotating rod 5, causing the rotating rod 5 to rotate together. This design ensures the movement synchronization between the connection seat 45 and the rotating rod 5, so that when the driving mechanism 2 drives the cam 41 to rotate, the rotating rod 5 can accurately reflect the state change of the switch.

[0037] like Figure 5 As shown, the connecting seat 45 is an inverted U-shaped seat, the bottom of the inverted U-shaped seat faces the cam 41, the opening of the inverted U-shaped seat faces the rotating rod 5, the limiting groove 451 is provided at the bottom of the inverted U-shaped seat, and the opening groove 452 is provided at the opening of the inverted U-shaped seat. The design of this inverted U-shaped seat not only simplifies the structure, but also improves the connection stability and accuracy between the components. Through the coordinated use of the limiting groove 451 and the opening groove 452, the smooth transmission between the connecting rod 42, the connecting seat 45 and the rotating rod 5 is ensured, thereby realizing the accurate indication of the switch state.

[0038] As a further improvement of the structure, the housing 1 is provided with an external status indication interface 6, such as Figure 2 and Figure 3 As shown, this interface allows the switch to be connected to an external device to transmit status information. A contact switch 7 electrically connected to the external status indication interface 6 is provided inside the housing 1, and a radially extending wing 53 is provided on the outer periphery of the rotating rod 5 at a position corresponding to the contact switch 7. This design ensures that when the rotating rod 5 rotates, the wing 53 can accurately contact or disengage with the contact 71 of the contact switch 7. When the wing 53 contacts the contact 71, the contact switch 7 is triggered, and then a connection signal is sent to the external status indication interface 6; when the wing 53 is disengaged from the contact 71, the contact switch 7 is disconnected, and a disconnection signal is sent to the external status indication interface 6. Through this design, the switch can transmit its own status information to the external device in real time, so that the user can clearly understand the current on-off state of the switch through the external device. This not only improves the intelligence level of the switch, but also provides users with a more convenient and intuitive means of status monitoring.

[0039] The external status indication interface 6 can be plugged into a device, which can be any device that can receive and display switch status information, such as an indicator light, a display screen, a computer, etc. In this way, the user can understand the status of the switch anytime and anywhere, so as to make more accurate and timely decisions. This is of great significance for the monitoring, management and maintenance of the power system.

[0040] In this embodiment, the indicator window 11 on the housing 1 is designed to be circular, and the indicator sheet 51 on the rotating rod 5 is designed to be fan-shaped. However, according to different application scenarios and design requirements, the shapes of the indicator window 11 and the indicator sheet 51 can be adjusted. For example, the indicator window 11 can be an ellipse, a square or other polygon, and the indicator sheet 51 can also be other parts with specific shapes and patterns. These different shapes can be used to create a more personalized and unique switch design to meet the personalized needs of users or the decoration requirements of specific occasions.

[0041] To further illustrate each embodiment, the present invention provides drawings. These drawings are part of the disclosure of the present invention, and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments.

At the same time, the front, back, left, right, etc. involved in this embodiment are only used as a reference for an orientation and do not represent the orientation in actual use.
