Description

Technical Field

[0001] The utility model relates to the technical field of electric switch signal detection, in particular to an electric switch signal detection device for a seat interlocking mechanism. Background Art

[0002] The interlocking mechanism on the seat is an important mechanism that affects the correctness of the seat startup procedure. Its essence is a combined mechanical lock with dual working states that are mechanically and circuit locked and connected in a fixed state. Under normal circumstances, the mechanism is in a locked state, the internal circuit is not connected, and the system does not work; according to the needs, the rocker arm is pulled to unlock the mechanism, thereby connecting the internal circuit, ensuring that the upper and lower circuits are connected, and the entire system is in working condition. There are two switches inside the interlocking mechanism. During the repair process, they need to be disassembled and inspected, and then reassembled. After assembly, the working reliability of the two switches needs to be tested. The specific operation process is to pull the rocker arm to switch the switch back and forth between the "on" and "off" positions, and check whether the output signal of the switch is reliable.

[0003] The existing circuit on-off is directly measured by a three-meter method. However, since the interlocking mechanism needs to monitor the on-off conversion of the circuit in real time during the whole process of testing, the measurement with a three-meter is single-purpose and lacks timeliness.
