Vehicle-mounted emergency rescue lighting device and control method thereof

Abstract

The invention discloses a vehicle-mounted emergency rescue lighting device and a control method thereof. The lighting device includes a control system, a lifting mechanism, a rotating and pitching assembly and at least two lighting lamps. The lifting mechanism includes a lead screw and a sleeve threaded therewith Tube, the rotating and pitching assembly includes a plurality of pitching motors connected to the lighting lamps through the pitching shaft, and a rotating motor connected to the left and right rotating shafts, and the pitching shaft and the left and right rotating shafts are respectively provided with multi-level limit assemblies. The device has powerful functions and strong adaptability. It can not only meet the needs of the same direction of irradiation, but also meet the needs of different directions of irradiation. The lifting action is more stable and reliable, and it has a self-locking function. The large-angle rotation and positioning ensure the demand for large-angle rotating lighting in the emergency rescue process, which is convenient for emergency operations; the control method uses the limit sensor of the lifting mechanism to ensure the safe operation of the device and realizes automatic reset.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted lighting devices, and in particular relates to a vehicle-mounted emergency rescue lighting device and a control method thereof. Background technique [0002] With the rapid development of my country's economy and urbanization, industries such as electric power, communication, transportation, fire protection, municipal administration, water supply, and gas supply have also developed rapidly, followed by emergency rescue work for various accidents. Increase, especially in places where there is a lack of lighting conditions for emergency rescue at night in the wild, providing all-round emergency lighting equipment can greatly improve the efficiency of emergency rescue, minimize the losses caused by various safety accidents, and avoid catastrophic accidents. [0003] Under the demand of the market, various emergency lighting vehicles have emerged, which integrate vehicle transportation, lightin...

Problems solved by technology

For example, the applicant applied for the emergency lighting vehicle with the patent number 200920089447.5 on April 7, 2009 and the 02270469.8 multifunctional emergency power supply vehicle applied for on October 29, 2002, and the announcement number published on April 2, 2014 is CN 203517565 U's patent name is vehicle-mounted mobile lighting equipment. The defects of these traditional vehicle-mounted lighting equipment are: 1) the rotation angle of the lighting lamp is limited, and it is difficult to achieve a large-angle rotation of more than 360 degrees; 2) usually two lighting lamps can only Synchronous pitching and rotation, and the lighting range is limited, it is impossible to realize that the two lights can rotate in different directions and illuminate in two different directions; 3) The lifting mechanism adopts a wire rope pulley mechanism, which has poor stability and is prone to slipping or entanglement of the wire rope situation, even after long-term use, there is a safety hazard of wire rope breakage
