Abstract
The utility model provides an automobile overload preventing device, relating to an accessory of the automobile. The automobile overload preventing device has simple structure, small size and low cost, which can be installed on the automobile. When the automobile is overloaded with goods, the automobile can not start and can send an alarm. The automobile overload preventing device comprises an induction mechanism, a control mechanism and an alarm mechanism. The induction mechanism is a limit switch A arranged at a set position under an automobile damper; the control mechanism comprises a switch, a power, a limit switch B arranged at the set position under the automobile damper, a delay relay and an intermediate relay. The alarm mechanism comprises an ignition coil, an engine and an audible and visual alarm; the deformation and the downward shift of the damper caused by the overload of the automobile can make the normally open contacts of the limit switch A and the limit switch B close to connect the delay relay and the power. When the set time reaches, the coil of the intermediate relay is connected to generate electric current; the audible and visual alarm can send an alarm; simultaneously, the ignition coil of the automobile is cut off and the automobile can not run.
Description
Technical field:
The present invention relates to a kind of annex of automobile.A kind of overload protection device of automobile particularly.
Background technology:
Automobile overload is the hidden danger of safety traffic, tends to cause overturn or train operation accident such as out of control.The measure that prevents automobile overload at present is; Laden automobile is reached on the on-ground weigher of surveying load carrying ability, judge with the method for measuring its load carrying ability whether automobile overloads.Owing to be subjected to surveying the restriction that the on-ground weigher of load carrying ability can not the shift position, this way can only Control of Automobile at the loaded weight that is provided with the place of surveying the load carrying ability on-ground weigher, can not control the heap(ed) capacity in the way of travelling, cause automobile to overload, and the driver is unknown, carry hidden danger and travel, very easily have an accident.
Summary of the invention:
The utility model aims to provide a kind of overload protection device of automobile.It is simple in structure, and volume is little, and cost is low, can install with car, can Control of Automobile can not start when overload, and report to the police.
The utility model comprises induction mechanism, control mechanism and alarm mechanism.
Induction mechanism is to be located at below the automobile absorber both limit switch A of allocation, and automobile overload causes that the distortion of bumper moves down the open contact closure that can make limit switch A;
Control mechanism comprises switch, power supply, be located at below the automobile absorber both limit switch B, slug relay, the intermediate relay of allocation; Automobile overload causes that the distortion of bumper moves down the open contact closure that can make limit switch B;
Alarm mechanism comprises high-tension coil, driving engine and combined aural and visual alarm;
Wherein, the com end of the com of limit switch A end, limit switch B is connected with the positive pole of power supply.The interface 1 of slug relay is connected with the no of limit switch A end, and interface 2 is connected with the no end of limit switch B, and interface 3 is connected with the interface 7 of intermediate relay, and interface 7 is connected with switch;
The interface 1 of intermediate relay is connected with high-tension coil, and interface 2 all is connected with positive source with interface 5, and interface 3 is connected with combined aural and visual alarm, and interface 6 is connected with driving engine, and interface 8 is connected with switch;
High-tension coil, combined aural and visual alarm, driving engine all is connected with switch, and switch is connected with power cathode.As Fig. 1, shown in Figure 2.
The utility model in use, when the automobile normal load, the open contact of limit switch A, limit switch B, slug relay and intermediate relay all is in open mode, the normally closed contact of intermediate relay is in closure state, after switch opens, electric current makes to cause engine operation by the high-tension coil normal ignition by high-tension coil.
When automobile overload, bumper is subjected to downward pressure and produces deformation displacement, in both set a distances, touches the pressure handle of limit switch A and limit switch B, and the action of pressure handle action makes the open contact closure of limit switch A and limit switch B.
The open contact closure of limit switch B can be with slug relay and power connection, after reaching set time, connects the intermediate relay coil and produces electric current.
The closure of limit switch A open contact, after middle relay coil produces electric current, can be so that the open contact closure of intermediate relay, connect combined aural and visual alarm and report to the police, and make normally closed contact disconnect simultaneously, cut off the automobile ignition wire loop current, cause and can not light a fire, automobile can not start.
In automobile is travelling the way, may cause the weightless or overweight of moment owing to jolt, cause the mistake of the open contact of limit switch A and limit switch B to bump, slug relay of the present utility model can make limit switch A and limit switch B open contact miss under the situation of bumping in moment, as long as be no more than the given time of in slug relay, setting, intermediate relay just can not start work, and automobile can cruising.
The utility model is applicable to gasoline to be the automobile of power, and for being the automobile of power with diesel oil, the electromagnetic valve device that high-tension coil need be changed into control oil channel can use.
In sum, the utility model is a kind of overload protection device of automobile.It is simple in structure, and volume is little, and cost is low, installs with car, can Control of Automobile can not start when overload, and report to the police.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model circuit theory scheme drawing.
Among the figure:
The 1-induction mechanism, 2-control mechanism, 3-alarm mechanism, 4-limit switch A, 5-switch, 6-power supply, 7-limit switch B, 8-slug relay, 9-intermediate relay, 10-combined aural and visual alarm, 11-high-tension coil, 12-driving engine.
The specific embodiment:
With the BJ-130 Light-duty Vehicle is example, and its nominal payload is 2T, and when automobile was unloaded, the free camber of the spring plate of automobile back wheel bumper was 132mm, and when loading to 2T, the spring plate camber of automobile back wheel bumper is 10.5mm.When camber＜10.5mm, the utility model starts.
At first, when travelling beginning, open switch 5 of the present utility model, because the distortion of the spring plate that automobile overload causes moves down, the pressure handle of the limit switch B7 of the limit switch A4 of induction mechanism 1 and control mechanism 2 is depressed, made the open contact closure of limit switch A4 and limit switch B7.Slug relay 8 connects with power supply 6, given time as slug relay 8 was made as 5 seconds, after reaching set 5 seconds time, power supply 6 is connected with intermediate relay 9, open contact closure behind the coil generation electric current of intermediate relay 9, power supply 6 is connected with alarm mechanism 3, its combined aural and visual alarm 10 is reported to the police, and make intermediate relay 9 normally closed contacts disconnect simultaneously, cut off automobile ignition coil 11, even behind car engine, high-tension coil 11 is not worked, driving engine 12 can not start, and automobile can not travel.
