Abstract
The utility model relates to an integral pedestrian warning device of electricelectric motor car, include the controller is connected with driving computer electricity, and speaker, characterized by are connected to the controller electricity: the controller passes through four fix with screws in an audio amplifier lower cover, the speaker passes through four fix with screws in an audio amplifier upper cover, audio amplifier lower cover and audio amplifier upper cover pass through the joint structure to together. The utility model discloses can send sound warning when electric motor car low -speed traveles, remind the pedestrian to notice, reduced safety accident takes place, its compact structure, what need arranges that the space is little, manufacturing cost is lower.
Description
Technical field
The utility model relates to pure electric vehicle day safe driving device, is specifically related to a kind of pure electric vehicle integral type pedestrian alarming device.
Background technology
Battery-driven car is when low speed, and vehicle noise is very low, and the traffic accident that row human or animal causes because being not easy to feel significantly is risen, and it is high 2 times that the report that safety traffic office of the U.S. (NHTSA) announces shows the pedestrian accident Hazard ratio conventional truck that noiseless vehicle causes.In order to the safety misadventure caused when reducing battery-driven car low speed driving, those skilled in the art have developed the multiple alarming device for battery-driven car.Disclosed in CN204340859U " battery-driven car low speed driving annunciator ", comprise: power port, described power port is powered to power management chip, described power management chip is powered to micro controller system, described power port is powered to voltage division processing circuit, described voltage division processing circuit is electrically connected with GPIO port, and described voltage division processing circuit is electrically connected with described micro controller system.Because electronlmobil does not have traditional power system driving engine, so its noise when low speed driving can be very low.The aspect that noise is low has been, but simultaneously bring unsafe factor, pedestrian is not easy to discover rear and sails the battery-driven car that comes and generation accident.This battery-driven car low speed driving annunciator can when battery-driven car low speed driving, warning of sounding, and reduces safety misadventure and occurs.Controller and the loud speaker of existing pure electric vehicle alarming device separate, and with 4 loud speakers, cost is higher, and the arrangement space needed is larger.
Summary of the invention
The purpose of this utility model is to provide a kind of pure electric vehicle integral type pedestrian alarming device, and it can when battery-driven car low speed driving, warning of sounding, and reminds pedestrian to note, reduces safety misadventure and occurs; Its compact conformation, the arrangement space of needs is little, and manufacturing cost is lower.
A kind of pure electric vehicle integral type pedestrian alarming device described in the utility model, comprise be electrically connected with car running computer controller, be electrically connected loud speaker with described controller, it is characterized in that: described controller is fixed in an audio amplifier lower cover by four screws, described loud speaker is fixed in an audio amplifier upper cover by four screws; Described audio amplifier lower cover and audio amplifier upper cover by interface arrangment to being combined.
Further, between the oral area and the oral area of audio amplifier upper cover of described audio amplifier lower cover, be provided with seal ring, leak with anti-gas-leak.
Further, described controller is pcb board, and this pcb board comprises CANBUS communication bus, numerical digit tuning module, audio amplification block, by CANBUS communication bus and car running computer communication.Controller need by car running computer receive car load IGN, power supply, bus signals, bus signals comprises ST signal, READY signal, vehicle speed signal, gear signal.
Further, described loud speaker is arranged on the front portion of battery-driven car, and to declivity 10 degree ~ 30 degree.
The beneficial effects of the utility model: this device can send driving sound to warn row human or animal when the battery-driven car speed of a motor vehicle is less than 20km/h or reversing, thus the generation of minimizing accident.After the speed of a motor vehicle reaches 20km/h (speed can adjust depending on real vehicle), the noise (comprising tire to make an uproar, motor noise etc.) of vehicle itself raises, and this alarming device stops sounding.
Accompanying drawing explanation
The pie graph of Fig. 1 alarming device;
The layout schematic diagram of Fig. 2 alarming device.
In figure: 1-audio amplifier lower cover, 2-seal ring, 3-controller (pcb board), 4-loud speaker, 5-audio amplifier upper cover, 10-battery-driven car.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of pure electric vehicle integral type pedestrian alarming device shown in Figure 1, comprise be electrically connected with car running computer controller 3, be electrically connected loud speaker 4 with described controller, it is characterized in that: described controller 3 is fixed in an audio amplifier lower cover 1 by four screws, described loud speaker 4 is fixed in an audio amplifier upper cover 5 by four screws; Described audio amplifier lower cover 1 and audio amplifier upper cover 5 by interface arrangment to being combined.Closely, the arrangement space of needs is little for its structure.
Between the oral area and the oral area of audio amplifier upper cover 5 of described audio amplifier lower cover 1, be provided with seal ring 2, leak with anti-gas-leak.
Described controller 3 is pcb board, and this pcb board comprises CANBUS communication bus, numerical digit tuning module, audio amplification block, by CANBUS communication bus and car running computer communication.Controller need by car running computer receive car load IGN, power supply, bus signals, bus signals comprises ST signal, READY signal, vehicle speed signal, gear signal.
See Fig. 2, described loud speaker 4 is arranged on the front portion of battery-driven car 10, and to declivity 30 degree; To make the sound sent upwards reflect with the elevation angle of 30 degree via ground, warning row human or animal dodge.
When the downward rake angle of loud speaker is 10 degree, 15 degree, 20 degree, 25 degree, namely form other embodiment.
The arrangement of loud speaker: the necessary waterproof of part of loud speaker, be installed to after on audio amplifier at loud speaker, waterproof washer must be used to guarantee in audio amplifier not influent gas completely, namely meet the classification of waterproof of IP67, the arrangement of pcb board: the spacing of pcb board and loud speaker is more far better.
The main material of components and parts on pcb board: select resistant to elevated temperatures electronic component, element adds surface spraying after having assembled, to improve resistance to environmental requirement; The main material of loud speaker: the formations such as retort stand+ferric oxide magnet+plastic cement vibrating diaphragm; The material of audio amplifier: plastic cement composite.
