Description
Technical field:
The utility model relates to a kind of automobile starting protective gear, relates in particular to a kind of automobile that prevents and starts once more and damage the control system of starter motor.
Background technique:
The situation bottom driver who is in the idling stagnation of movement at automobile duplicates the situation of ato unit easily, particularly drive new hand, be easy to pilot engine once more with ignition key, chief reason is that present vehicle is when being in engine idle, in operator cabin, can't hear the sound of engine operation basically, thereby think not starting, so rise again and make a movement, when hearing that starter motor is worked abnormal sound once more, understand that just vehicle has been to be in idling mode, can cause infringement to the overrunning clutch of starter motor this moment.Chinese invention patent 200410027141.9 discloses a kind of automobile, motorcycle initiating protective gear; this startup protective gear structure is: comprise the signal voltage input circlult; detect control circuit and electronic switch; the input end of signal voltage input circlult is connected in the voltage signal output end of engine operation; the output terminal of signal voltage input circlult is connected with the input end that detects control circuit; the output terminal that detects control circuit is connected with the control end of electronic switch, and electronic switch is series between the tail end and COMMON of starting relay field coil.Its principle is: power supply is given starting relay through enable switch button or brake switch, and this moment, electronic switch was a closed state, and starting electrical machinery drives motor, and motor is activated.Behind the engine start, magnetogenerator is outwards powered.The voltage signal of engine operation is delivered to the input end that starts protective gear through the input end of signal voltage input circlult; after being identified, this voltage signal delivers to electronic switch; electronic switch just enters the disconnection self-locking state; no matter in start-up system, do which kind of operation; all badly cause starting electrical machinery to be devoted oneself to work again, reach the purpose of protection start-up system and starting electrical machinery.But this apparatus structure more complicated, the manufacture cost height.
Summary of the invention:
The utility model has mainly solved the problem that above-mentioned prior art exists, and a kind of simple and reasonable automobile starting protective gear is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of automobile starting protective gear; be arranged between starting relay and the power supply; it is characterized in that: the automobile starting protective gear comprises electronic control module, special purpose relay; the input end one of described electronic control module links to each other with power supply; input end two links to each other with the engine rotational speed signal line; its output terminal links to each other with the coil of special purpose relay; this coil the other end is connected to power supply; contact one end of special purpose relay is connected on the contact of starting relay, and the other end links to each other with Starter.This device is controlled the break-make of corresponding consumer circuit by supply voltage and engine rotational speed signal, to realize preventing to pilot engine once more to the hurtful purpose of the overrunning clutch of starter motor.
The utility model has the advantages that simple in structure, low cost of manufacture, reasonable in design, and by electronic control module control, its accuracy and reliability are better, the most important thing is that it practically is worth very highly, various vehicles can be general, and are more safe and practical.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of circuit line chart of the present utility model.
Embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.
Embodiment:
The utility model automobile starting protective gear 1 is arranged between starting relay 3 and the power supply 6; it mainly comprises electronic control module 4 and special purpose relay 2; input end 1 pin of described electronic control module links to each other with power supply 6; input end 3 pin link to each other with the engine rotational speed signal line; its output terminal 2 pin link to each other with the coil of special purpose relay 2; this coil the other end is connected to power supply 6; switch one end of special purpose relay is connected on the switch of starting relay, and the starting relay switch the other end links to each other with Starter 5.Electronic control module 4 in the utility model is chip APMEL169.
Before starting ignition switch not, because of there not being power supply, starting relay is work not, the electronic control module of this device also is in off position, the contact of that special purpose relay and low level are paths, the coil that is starter relay is to be in channel status, this moment press ignition switch pilot engine for the first time no problem fully;
After pressing ignition switch and piloting engine; two input end leads of the electronic control module of this device receive voltage signal (＞12V) and engine signal (＞500 change); control module is through computing; output low level signal in 300 milliseconds; make the special purpose relay work that is in the starting relay series circuit; the contact that is exactly special purpose relay connects sky; thereby disconnect the coil path of starter relay; when the driver wants to adopt ignition key to pilot engine once more; starter relay is in off position all the time, thereby has reached the effect of protection starter motor.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technician of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as starting relay, special purpose relay morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
