[0019] Embodiment Please refer to Figures 1-5 As shown in the figure, the utility model provides a kind of power switch with state detection, including shell 1, pivot 2 is arranged in shell 1, pivot 2 is equipped with power component 3 for on-off main power loop, and detection component 4 for generating state detection signal; As Figure 2 As shown, detection component 4 includes: microswitch 401 and switch positioning sheet 402, wherein microswitch 401 is installed on shell 1, switch positioning sheet 402 is installed on pivot 2, switch positioning sheet 402 is configured to rotate to preset angle with pivot 2, trigger microswitch 401 action to generate on-off state of power switch The on-off electric signal that represents.

[0020] In the embodiment, second protruding part 9 is provided on switch positioning sheet 402, and the specific structure is as shown in Figure 2 、 Figure 3 As shown, the second protruding part 9 is used to touch and press microswitch 401 to generate on-off electric signal, and the electric signal is output to the outside.

[0021] The terminal part of microswitch 401 is connected with plug connector 5, and the plug connector 5 is used to be connected with external remote device, to facilitate real-time remote monitoring of on-off state of equipment power supply.

[0022] like Figure 2 , Figure 3 As shown, the power supply assembly 3 includes: a base 301, two terminals 302, and an actuating piece 303. The base 301 is fixedly mounted on the housing 1, the two terminals 302 are fixed on the base 301, and the ends of the two terminals 302 protrude outside the base 301. The actuating piece 303 is mounted on the rotating shaft 2 and has two first protrusions 7. The two first protrusions 7 are coated with industrial petroleum jelly to reduce friction.

[0023] In this embodiment, the actuating piece 303 can be slidably arranged along the rotating shaft 2, and a spring 6 is provided between the actuating piece 303 and the switch positioning piece 402.

[0024] The actuating piece 303 has an opening with rotation restriction inside. This opening is adapted to the shape of the end of the rotating shaft 2, which can effectively prevent the actuating piece 303 from rotating relative to the rotating shaft 2 during operation. Its specific structure is as follows: Figure 4 As shown.

[0025] The base 301 has an insulating sheet 8 inside. This design can effectively isolate the internal conductive components and prevent accidental short circuits or leakage, thereby significantly reducing the safety risks caused by electrical faults and improving the overall safety of the switch.

[0026] like Figure 5 As shown, a switch handle 10 is installed at the end of the rotating shaft 2. A handle seat 11 is provided between the switch handle 10 and the housing 1. The handle seat 11 is installed on the housing 1 by a fastener. At the same time, the handle seat 11 and the housing 1 are precisely positioned and fixed by a positioning pin 12.

[0027] It should be noted that in this embodiment, the positions of the first protrusion 7 on the touch piece 303 and the second protrusion 9 on the switch positioning piece 402 are relatively fixed. When the first protrusion 7 contacts the terminal 302 to realize the main circuit switching, the second protrusion 9 synchronously triggers the micro switch 401 to generate a status detection signal, thereby ensuring the strict timeliness and synchronization of mechanical switching and electrical signal output.

[0028] This utility model's power switch is particularly suitable for electric construction machinery (such as electric excavators and electric loaders) that uses a DC / DC power supply system. In this application scenario, the detection component 4 serves as an "auxiliary contact" to provide feedback on the switch status to the vehicle control unit (VCU). When the maintenance personnel rotate the switch handle 10 to the "OFF" position to cut off the vehicle's power supply, the switch positioning piece 402 immediately disengages from the microswitch 401, causing its output conduction signal to disappear. After the VCU monitors this status change in real time through the plug connector 5, it can immediately issue a command to the power distribution unit (PDU), thereby reliably disconnecting the vehicle's high-voltage power supply. This mechanism effectively solves the safety hazard of traditional mechanical switches being unable to handle high-voltage electricity, providing double safety assurance for equipment maintenance and greatly improving operational safety.

[0029] The working principle is as follows: When the operator turns the switch handle 10 to turn on the power switch, the rotating shaft 2 rotates synchronously, causing the switch positioning plate 402 and the trigger plate 303 to rotate together. When the two first protrusions 7 on the trigger plate 303 reliably contact the two terminals 302, the main power circuit is energized; at the same time, the second protrusion 9 on the switch positioning plate 402, which has been rotated into position, synchronously triggers the micro switch 401 to act, generating a detection signal that represents the on / off state.

[0030] Throughout the process, the spring 6 provides appropriate axial pressure to the actuating piece 303 to ensure stable contact between the first protrusion 7 and the terminal 302; at the same time, it allows the actuating piece 303 to undergo slight axial displacement during rotation to adapt to contact requirements and improve connection reliability.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
