Description

Car parking door opening sound-light reminding device

Technical field

The utility model belongs to application of electronic technology and technical field of automotive electronics, is about a kind of car parking door opening sound-light reminding device.

Background technology

It is part minor matter that door opening seems, but the damage that accident causes generally all is compared seriously, because door opening is taken by surprise. Particularly electronic bike rapidly increases in recent years, the speed of a motor vehicle generally the too fast probability also allowing this type of accident occur increase further. According to incompletely statistics: in these accidents, 60% all relates to electronic bike, and the ratio that taxi has an accident is the highest, about about 30%. In addition, the accident ratio that sedan car door opening causes is about about 60%, and other type of vehicle open the door the accident caused about about 10%.

The traffic police of accident settlement explain, this is because part renting car driver races against time, inadequate specification when often stopping, forgets again passenger to be reminded sometimes, having neglected during enabling and first observed door opening again, result causes open the door accident of thrusting into of passenger to happen occasionally generation. In the accident that taxi and car cause, mostly open what car door caused by passenger, and the accident caused of opening the door by driver also occupies certain ratio.

How does maximum degree prevent " door opening " accident from occurring? the heaviest is, and unoperated position to be chosen to open the door first opens bar seam! Before opening the door, before and after reply, pedestrians, vehicle condition note observing, and just can open the door after confirming safety, person for driving a car especially taxi people by bus also should be reminded before opening the door in time; Except officer, people gets off from right side as far as possible by bus.

Car parking door opening sound-light reminding device described in the utility model utilizes electronic technology means, sends sound and light alarm in the moment of door opening, reminds personnel by bus to note the running condition of vehicle below.

Car parking door opening sound-light reminding device described in the utility model involved necessary, key technology contents in implementation process is described below in detail.
