Abstract
The utility model relates to an electric cab lifting protection device. The electric cab lifting protection device comprises a hinging seat installed on a forward-overturning bumper, a hinge which is installed on the hinging seat in a rotating mode and is fixed to a radiator grille, a contact-type electromagnetic switch which is installed on the hinging seat and is used for detecting whether the hinge overturns or not, an electromagnetic valve, an oil pump connected to the electromagnetic valve and a lifting starting switch. The input end of the contact-type electromagnetic switch is connected to the output end of a storage battery, and is connected with the lifting starting switch. When the radiator grille of a cab is closed, the hinge is not close to the contact-type electromagnetic switch, and the storage battery is not connected with the lifting starting switch at this moment; when the radiator grille of the cab is opened, the hinge is close to the contact-type electromagnetic switch to trigger the contact-type electromagnetic switch to connect the storage battery and the lifting starting switch, the electromagnetic valve can turn as long as the lifting starting switch is pressed at the moment, and accordingly the oil pump works and the cab is pushed by a hydraulic cylinder to rise.
Description
Technical field
The utility model relates to automobile technical field, is specifically related to a kind of fender guard.
Background technology
At present the heavy-duty vehicle of tack all can require the operator will at first open the radiator grille of operator's compartment when the operator's compartment lifting, in case during the operator's compartment lifting, because front upset bumper/spoiler and radiator grille occur to push, cause vehicle damage.The operation consciousness of this operating mode based on operating personal, open radiator grille and the operator's compartment that overturns by force if the operator forgets, will cause to damage to occur.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of radiator grille of not opening, and overturn system will be refused the operator's compartment electric hoisting fender guard of rotary movement automatically.
The utility model overcomes the technical scheme that its technical matters adopts:
This operator's compartment electric hoisting fender guard; comprise the hinged seat that is installed on front upset bumper/spoiler, rotate and be installed on hinged seat and be fixed in hinge on radiator grille, be installed on contact electromagnetic switch, the electromagnetic valve whether overturn for detection of hinge on hinged seat, the oil pump that is connected in electromagnetic valve and lifting starting switch, described contact electromagnetic switch input end is connected in its mouth of storage battery and is connected with the lifting starting switch.
In order to prevent from burning circuit, also comprise a circuit insurance, described circuit insurance is connected between storage battery and contact electromagnetic switch.
The beneficial effects of the utility model are.
The accompanying drawing explanation
Fig. 1 is operator's compartment radiator grille closed condition structural representation of the present utility model;
Fig. 2 is operator's compartment radiator grille open mode structural representation of the present utility model;
Fig. 3 is circuit system structure schematic diagram of the present utility model;
In figure, 1. hinge seat 2. hinge 3. contact electromagnetic switch 4. storage battery 5. circuit insure 6. lifting starting switch 7. oil pump 8. electromagnetic valves.
The specific embodiment
Below in conjunction with accompanying drawing 1, accompanying drawing 2,3 pairs of the utility model of accompanying drawing, be described further.
This operator's compartment electric hoisting fender guard; comprise the hinged seat 1 that is installed on front upset bumper/spoiler, rotate and be installed on hinged seat 1 and be fixed in hinge 2 on radiator grille, be installed on contact electromagnetic switch 3, the electromagnetic valve 8 whether overturn for detection of hinge 2 on hinged seat 1, the oil pump 7 that is connected in electromagnetic valve 8 and lifting starting switch 6, described contact electromagnetic switch 3 input ends are connected in storage battery 4 its mouths and are connected with lifting starting switch 6.As shown in Figure 1, when the operator's compartment radiator grille is closed, hinge 2 is not close with contact electromagnetic switch 3, and now storage battery 4 and the 6 not conductings of lifting starting switch, also can't realize that electromagnetic valve 8 actions make oil pump 7 work even press lifting starting switch 6.As shown in Figure 2, when the operator's compartment radiator grille is opened, hinge 2 is close with contact electromagnetic switch 3, thereby trigger contact electromagnetic switch 3 conducting storage batterys 4 and lifting starting switch 6, now press lifting starting switch 6 and can make electromagnetic valve 8 commutations, thereby make oil pump 7 work, thereby oil cylinder pushing operator's compartment lifting.By this operator's compartment electric hoisting fender guard, realized not guaranteeing not lifting of operator's compartment when the operator's compartment radiator grille is not opened, avoided forgetting and opened radiator grille and the operator's compartment that overturns by force causes and damage to occur.
Also comprise a circuit insurance 5, described circuit insurance 5 is connected between storage battery 4 and contact electromagnetic switch 3.When the excessive situation of electric current occurring, circuit insurance 5 can disconnect being connected between storage battery 4 and circuit system, prevents circuit burnout.Reliability and the safety used have been guaranteed.
