Abstract
The utility model discloses a fault-safe processing device of a trailer, relating to a vehicle-mounted safety device. In the existing technical scheme, the trailer unhooking alarm device does not handle the faults of the trailer, only makes warning to a driver and completely needs the driver to handle the faults after judging the conditions. The fault-safe processing device of the trailer comprises an alarm box; the alarm box is internally provided with a switch which is connected with a pull rope; two ends of the switch are respectively connected with a power supply and an alarm circuit which is connected with an electric magnet in parallel. When being unhooked, the trailer makes alarming to the driver by the sound and a warning light, attracts a brake pedal by the electric magnet, and automatically brakes, and the whole fault-safe processing device responses in time, can avoid or reduce the accident hazard caused by unhooking of the trailer, and has simple structure and convenient use.
Description
[technical field]
The utility model relates to safeguard device vehicle-mounted safety device, the specifically a kind of fault alarm on the trailer and device of processing of being used for.
[background technology]
General trailer is suspended on the tractor truck by hook, be easy in the process of moving break off relations, and chaufeur can't know whether trailer breaks off relations, only after breaking away from tractor truck, just can realize by trailer, and had no time often this moment to deal with to chaufeur, so the traffic tragedy that the trailer unhook causes happens occasionally.
China Patent No. is the switch that the disclosed trailer safety alarm of 9225232.4 utility models adopts plug-type, plug is positioned on the trailer, socket is positioned on the tractor truck, prop up spring leaf by plug, if break off relations, then plug is extracted, spring leaf contact closing point, switch closure, warning circuit forms the loop, realizes reporting to the police.Its weak point is the processing that does not relate in the scheme fault, just makes caution to chaufeur, needs chaufeur to judge then and there situation and deal with in the very brief time, and the long-term state that propped up of keeping of spring leaf, follows the string easily.
[utility model content]
In order to address the above problem, the utility model provides a kind of unhook to report to the police and the self-stopping safety device of energy, and simple installation uses durable.
The technical solution of the utility model is as follows: a kind of trailer fail safe processing equipment, comprise a warning box, and a switch is set in the warning box, connect a stay cord on the switch; The two ends of switch connect power supply and warning circuit respectively, warning circuit and electromagnet parallel connection.Trailer is if break off relations, and stay cord is pulled on switch, and warning circuit and electromagnet form the loop, and the prompting chaufeur breaks down, and electromagnet attracts brake pedal to realize self-actuating brake.
Described switch comprises that one is installed in the insulative pin in the warning box, in the both sides of latch cooresponding hollow cylinder is set, and hollow cylinder inside is provided with spring, and spring one end connects power lead, and the other end connects a contact, and contact is against on the latch.Stay cord is pulled out latch, two contact contacts, and circuit forms the loop.
Described latch two sides are provided with groove, and an end of hollow cylinder puts in fillistered joint and contacts the latch inwall, and the latch inner wall thickness reduces, and prevent to skid easily during the contact of two contacts because inner wall thickness is excessive to be caused the telescopic spring amplitude to strengthen and follow the string easily.
Described latch one end is provided with draw ring and is exposed at outside the warning box, and draw ring connects stay cord, and other end head is taper.Latch one termination portion fines away, and latch is turned back to smoothly be not drawn out preceding position.
Have a through hole in the middle of the described electromagnet, bore periphery is provided with louvre.Through hole is used for connecting brake pedal, and cross through hole does not have cross travel after making and connecting.
Described warning circuit comprises Warning light and voice guard, and both parallel connections can realize the dual warning of sound and Warning light.Described Warning light is a three-color LED light, compares common Warning light and attracts the chaufeur attention more.
Outstanding advantage of the present utility model is in the trailer unhook, stay cord is pulled on after the switch, by sound with Warning light is dual makes warning to chaufeur, and attract brake pedal by electromagnet, self-actuating brake, the total system reaction is in time, can avoid or reduce the accident harm that trailer breaks off relations and causes, simple in structure, easy to use durable, can also be applied to the such two sections connections of other similar trailers needs the security monitoring part.

[specific embodiment]
Below in conjunction with accompanying drawing the utility model is done detailed description.
Embodiment 1: connect by hook between tractor truck and the trailer, hook is positioned on the trailer, referring to Fig. 1-3, a kind of trailer fail safe processing equipment, power supply 1 is fixed on one's body the trailer by screw rod, warning box 2 is arranged on trailer one side, power supply 1 picks out the switch 6 in the lead connection warning box 2, the other end of switch 6 has connected voice guard 7, Warning light 3 and the electromagnet 4 in the warning box, have a cross through hole in the middle of the electromagnet 4, bore periphery is provided with louvre, and through hole is used for connecting brake pedal.Warning light 3 is selected three-color LED light for use, and its flicker the time is compared the attention that common Warning light attracts chaufeur more, and Warning light 3 weight are lighter, can be installed in the operator's compartment, also can be installed on the car position where just chaufeur check of taking up an official post.
Described switch 6 comprises that one is installed in the insulative pin 8 in the warning box, and latch 8 one ends are provided with draw ring 11 and are exposed at warning box 2 outer and connect stay cord 5, and other end head is taper.In its both sides cooresponding hollow cylinder 9 is set, cylindrical inside is provided with spring, and spring one end connects power lead 10, and the other end connects contact, and contact is against on the latch 8.Stay cord 5 is pulled out 8, two contact contacts of latch, switch 6 closures, and circuit forms the loop, and latch 8 one termination portions fine away, and latch 8 is turned back to smoothly be not drawn out preceding position.
Described latch 8 two sides have groove, and recessing reduces latch 8 inner wall thickness, prevent because inner wall thickness is excessive to be caused the telescopic spring amplitude to strengthen following the string easily, use not durablely, and two contacts skid when contacting easily.
