The invention belongs to the field of switch control, and particularly relates to an undercarriage compression switch special mechanism adaptive to a proximity switch, which comprises a fixed part and an upper torque arm, the upper torque arm is hinged to the fixing piece through a rotating shaft. A target is arranged at one end, far away from the rotating shaft, of the connecting rod; when the target is located at the preset position, the proximity switch is arranged at the position away from the target by the preset distance, that is, when the upper torque arm rotates, the rotating shaft is driven to rotate so that the connecting rod can move, the position of the target can be changed at the moment, the proximity switch is provided with a sensor, and the position of the target can be changed by sensing the movement of the target. Generating a required signal; by adopting the scheme, the problems of adapting to a proximity switch, adapting to high-load and impact working conditions of takeoff of an aircraft and stably and reliably outputting the compression bearing signal of the undercarriage can be effectively solved, and the acquisition requirements of systems on the aircraft on the compression bearing signal of the undercarriage are ensured.
本申请属于开关控制领域,特别涉及一种适配接近开关的起落架压缩开关特种机构,包括:固定件,上扭力臂;上扭力臂通过转轴与固定件铰接;转轴的径向一位置处铰接有连杆,连杆远离转轴的一端具有靶标;连杆中部一位置处通过摇臂与固定件铰接,在靶标处于预设位置时,在与靶标预设距离处设置接近开关,也就是说,在上扭力臂转动时,带动转轴转动,从而使连杆运动,此时的靶标会改变位置,而接近开关具有传感器,通过感应靶标的运动,产生需要的信号;采用上述方案能够有效解决适配接近开关,适应飞机起飞高载荷和冲击工况,稳定可靠输出起落架压缩承载信号输出的问题,保证了机上各系统对起落架压缩承载信号的采集需求。
