Abstract

The utility model relates to starting equipment of an engine, in particular to equipment capable of preventing startup of an automobile during overturn of a cab. The equipment comprises a power supply, a starter, an ignition lock and a starting relay, wherein one end of each of the contacts of the starter, the ignition lock and the starting relay is connected to the power supply, the other end of the contact of the starting relay is connected to the starter, the equipment further comprises a limit switch, one end of the limit switch is connected to the ignition lock, and the other end of the limit switch is connected to a coil of the starting relay. According to the equipment, the limit switch is arranged between the cab and a frame, so that when the cab has a tilting angle, the connection between the ignition lock and the starting relay is cut off, thus the engine cannot start through a key of the automobile, and the danger due to the wrong startup of the engine by a driver can be avoided when the cab overturns.

Description

During a kind of driver's cab turnover, prevent the equipment of automobile start

Technical field

The utility model relates to the starting device of driving engine, prevents the equipment of automobile start while being specifically related to a kind of driver's cab turnover.

Background technology

Cab-over-engine truck operator's compartment can overturn forward so that adjust and maintainer carry out detection of dynamic and maintenance be a large advantage of such operator's compartment, can fire an engine by car key and starter button under rollover states, so there is communication mistake or the crude and rash maloperation of personnel under occupant and Che, cause driving engine false starts to produce dangerous.

Utility model content

The equipment that prevents automobile start when technical problem to be solved in the utility model is to provide a kind of driver's cab turnover cannot start operator's compartment driving engine under rollover states.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: the equipment that prevents automobile start during a kind of driver's cab turnover, comprise power supply, starter, ignition lock and starting relay, one end of the contact of described starter, ignition lock, starting relay is all connected with described power supply, the other end of the contact of described starting relay connects described starter, also comprise limit switch, one end of described limit switch connects described ignition lock, and the other end of described limit switch connects the coil of described starting relay.

The beneficial effects of the utility model are: while making operator's compartment have flip angle by a limit switch is installed between operator's compartment and vehicle frame, disconnect being connected between ignition lock and starting relay, driving engine cannot be started by car key.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, described ignition lock comprises STAR starting circuit, and one end of described limit switch connects described STAR starting circuit.

Further, described limit switch is located between automobile chassis frame and operator's compartment, and described limit switch is positioned at the rear end of described operator's compartment.

Adopt the beneficial effect of above-mentioned further scheme to be: limit switch is arranged on to the rear end of operator's compartment, makes operator's compartment under the upset of smaller angle, limit switch also can detect and obtain, make signal of the present utility model source more accurate.

Accompanying drawing explanation

Fig. 1 is the position view of the utility model limit switch;

Fig. 2 is schematic diagram of the present utility model.

In accompanying drawing, the parts of each label representative are as follows:

1, limit switch, 2, starter, 3, starting relay, 4, ignition lock, 5, power supply, 6, ground wire, 7, automobile chassis frame.

The specific embodiment

Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

As shown in Figure 2, during a kind of driver's cab turnover, prevent the equipment of automobile start, comprise power supply 5, starter 2, ignition lock 4 and starting relay 3, described starter 2, ignition lock 4, one end of the contact of starting relay 3 is all connected with described power supply 5, the other end of the contact of described starting relay 3 connects described starter 2, also comprise limit switch 1, one end of described limit switch 1 connects described ignition lock 4, the other end of described limit switch 1 connects the coil of described starting relay 3, the other end ground connection of the coil of described starting relay, described limit switch 1 is opened when operator's compartment is dug, play the effect of clear the circuit, this limit switch can other have the equipment replacement of relative position output with position transduser etc.

Described ignition lock 4 comprises STAR starting circuit, and one end of described limit switch connects described STAR starting circuit, controls the break-make of STAR start-up circuit by limit switch.

As shown in Figure 1, described limit switch is located between automobile chassis frame 7 and operator's compartment, and described limit switch 1 is positioned at the rear end of described operator's compartment, so that operator's compartment is under the upset of smaller angle, limit switch also can detect and obtain.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
