Abstract
The utility model belongs to the automotive collision device technical field, in particular to an automotive rear collision device, which is characterized in that the device consists of a fixing frame, a flexible bumper, a contact bar, a positive and negative motor, a power-off switch, an alarming switch, a braking switch, a return spring and a braking part component, wherein the flexible bumper fixed on the fixing frame can be flexed front and back, the contact bar, the return spring, the alarming switch and the braking switch are arranged on the flexible bumper. The device automatically makes the automobile switched off and braked without contacting the object when the automobile is backing, thereby effectively preventing the backing accident. The utility model can be applicable to various automobiles of large, medium and small sizes.
Description
The utility model belongs to the anti-collision device for automobile technical field, particularly a kind of automobile tail anticollision device.
Existing automobile is when reversing, for preventing to bump the people or hitting other object, and on the one hand by eye-observation control, automobile also is provided with reversing light and voice prompting device with the safety of raising reversing automobile on the other hand.But light and voice prompting device are then inoperative to blind person or old man and other object etc., and it can only be to work when light is bright that the driver observes by eyes, during dim light or driver's reversing at night then very difficult, and cause the reversing accident.
The purpose of this utility model is to design a kind of later-model automobile tail anticollision device at have the above-mentioned difficulties that exists now when moveing backward, this device can not contact object and just makes the automobile flameout brake automatically when reversing automobile, thereby has an accident when effectively avoiding moveing backward.
The technical characterictic of this automobile tail anticollision device be it by fixed mount, retractility bumper/spoiler, feeler lever, clockwise and anticlockwise motor, cut-off switch, alarm switch, BK Brake Switch, pull back spring, brake member form, the retractility bumper/spoiler is packed in can be elastic on the fixed mount, feeler lever, pull back spring, alarm switch, BK Brake Switch parts are packed on the retractility bumper/spoiler, clockwise and anticlockwise motor, cut-off switch are packed on fixed mount and the retractility bumper/spoiler, and BK Brake Switch links to each other with brake member by lead.Automobile is damaged when alleviating the retractility bumper impact, on fixed mount, be provided with damping spring, when the retractility bumper/spoiler is subjected to heavy bump, can alleviate impact in the use.For the retractility bumper/spoiler resistance that can stretch in fixed mount is reduced, can be provided with pulley in the junction of fixed mount and retractility bumper/spoiler, can reduce its flexible resistance by pulley action.Fixed mount is the parts that this anticollision device links to each other with automobile, also is the fixing main body of other parts of anticollision device, and anticollision device is packed in the afterbody of automobile during use by fixed mount.The retractility bumper/spoiler is the object of telescopic bumper/spoiler effect in fixed mount, and the front portion of retractility bumper/spoiler is provided with feeler lever, and the feeler lever back is provided with alarm switch, BK Brake Switch and pull back spring.Feeler lever is the object that touches alarm switch and BK Brake Switch, because feeler lever is the object that very easily collides, and its using strength height, the material of surperficial preventing from scar is made.Alarm switch is the press-type alarm switch, and its available buzzing formula or speech type are reported to the police.BK Brake Switch also is the press-type switch, and it is the switch that starts brake member, and alarm switch and BK Brake Switch can be divided and be arranged, and also can merge setting.Clockwise and anticlockwise motor is the flexible power of retractility bumper/spoiler, it can rotate and reverse, it is a DC machine, the retractility bumper/spoiler stretches out when just changeing, it is withdrawn in the fixed mount again during counter-rotating, clockwise and anticlockwise motor is just changeing by automotive reverse gear to be controlled, automobile one engage a gear, then connect clockwise and anticlockwise motor, clockwise and anticlockwise motor is then released the retractility bumper/spoiler backward by stay cord, and the back extruding power-off switch that puts in place then has a power failure and stops just to change, and reverse gear is removed and then connected clockwise and anticlockwise motor, the clockwise and anticlockwise motor counter-rotating is with the withdrawal of retractility bumper/spoiler, and extruding cut-off switch in withdrawal back makes the clockwise and anticlockwise motor outage.Pull back spring is to make the feeler lever return break away from the parts of alarm switch and BK Brake Switch.Brake member is to move the parts that power-transfer clutch and brake part make automobile emergency brake, and it can be finished by motor or electromagnetic valve, and motor or electromagnetic valve all are contained on the master cylinder, and it is controlled by BK Brake Switch.
During use, after reverse gear was hung up, the retractility bumper/spoiler slowly stretched out in the clockwise and anticlockwise motor effect, fell if run into object behind the automobile, and feeler lever can push alarm switch and BK Brake Switch at once, and warning also starts the brake member emergency brake, thereby avoids the generation of accident.Reverse gear is removed back retractility bumper/spoiler withdrawal.If do not need to use the retractility bumper/spoiler to stretch out, can cut off the clockwise and anticlockwise motor power supply during reverse gear by source switch.When automobile does not fall by other automobile when bump against at the rear portion back, then can under the damping spring effect, reduce impulsive force, alleviate automobile is damaged
This device can effectively be avoided the reversing accident, has eliminated some safety hazard, has brought bigger convenience to chaufeur, and this device can be suitable for using on all kinds of automobiles of large, medium and small type.
Fig. 1 is embodiment master's TV structure scheme drawing of the utility model automobile tail anticollision device.
Among Fig. 1: 1 fixed mount; 2 retractility bumper/spoilers; 3 clockwise and anticlockwise motors; 4 stay cords; 5 cut-off switchs, 6 power-off switches; 7 feeler levers; 8 BK Brake Switch; 9 pull back springs; 10 pulleys; 11 damping springs; 12 brake members; 13 power-transfer clutchs; 14 brake parts, it is stopped for gas; 15 alarm switches.
Claims (3)
1. automobile tail anticollision device, it is characterized in that it is made up of fixed mount, retractility bumper/spoiler, feeler lever, clockwise and anticlockwise motor, cut-off switch, alarm switch, BK Brake Switch, pull back spring, brake member parts, the retractility bumper/spoiler is packed in can be elastic on the fixed mount, feeler lever, pull back spring, alarm switch, BK Brake Switch parts are packed on the retractility bumper/spoiler, clockwise and anticlockwise motor, cut-off switch are packed on fixed mount and the retractility bumper/spoiler, and BK Brake Switch links to each other with brake member by lead.
