Description

Vehicle-mounted abduction alarm device

Technical field

This utility model relates to technical field of automotive electronics, particularly relates to a kind of vehicle-mounted abduction alarm device.

Background technology

At present, the event causing people's injures and deaths because grabbing vehicle happens occasionally.When facing this type of event, it is ensured that personal safety is forever Far it is placed on primary.The product in this field uses and is concentrated mainly on tax services industry at present, has automobile safety protective Dividing plate and automobile top install two kinds of close products of comparison of LED alarm panel.

Security protection dividing plate: guard screen uses the lucite material of all-transparent, in order to make driver safer, will adopt By " be close to and enclose " mode, heel row will keep apart with front row, and driver and copilot station also will separate with guard screen.This Outward, in order to not allow the passenger of front passenger's seat feel the most oppressive, dividing plate has one downward " gradient " between positive front passenger's seat, Plate apex distance about 30 centimetres from roof.Use " be close to and enclose " isolation, can effectively prevent the cutter direct injury to driver.On dividing plate Open an oval osculum the most specially, just accommodated a fist and put in, " this is in order to taxi driver brother collects money conveniently ".

LED warning function: the control knob of LED alarm panel, is exactly the button of GPS alarm in fact.If taxi driver brother feels It is on the hazard, it is possible to stealthily press the button in interior shelter of getting off, then while connecting alarm platform, on roof lamp LED screen, will constantly flash the printed words of " I is robbed, and please report to the police ".So, as long as the section of taxi process has people to see Arrive, it is possible to help taxi driver brother to report to the police.

This two product, although the person peace of the people that is held as a hostage can be effectively protected to a certain extent when robbery occurs Entirely, but the place still having several drawbacks.Such as: install and just become the numbest to passenger's ticket of going by taxi after security protection dividing plate Tired.Further, to close the window just in case raining, or passenger getting off car tail gate does not shuts, and settles once stretching with remote holder, is now to down Car.It addition, for domestic passenger car, it is contemplated that attractive in appearance and practicality, this two product all unsuitable for.

Utility model content
