Description
Technical field
The present invention relates to all kinds of engineering machinery, such as the production technical field of excavator, loading machine, crane driver's cabin,
Particularly electromangnetic spectrum.
Background technology
The phenomenon that interaction variation in electric field and magnetic field can generate electromagnetic wave, electromagnetism wave direction air-launched or leakage is electromagnetism spoke
It penetrates, excessive electromagnetic radiation has resulted in electromagnetic pollution.As electronics, electric equipment products increase, Contamination of Electromagnetic Wave getting worse,
The fourth-largest pollution after air pollution, water pollution and noise pollution is become.
Electromagnetic shielding refers to that electromagnetic wave is reflected and absorbed, so as to make the energy of electromagnetic wave when electromagnetic wave passes through shield
Measure the process reduced.Related experiment shows：If the material good conductor of shield, the effect of electromagnetic shielding can be more preferably.
Although engineering machinery driving cabin is largely metal material, electromagnetic wave can be shielded, the glass of windowpane
The rubber weather strip of glass and car door cannot but shield electromagnetic wave, if high-strength in radar base station, high voltage transmission line and substation etc.
When working in the electromagnetic wave environment of degree, electromagnetic wave can enter driver's cabin from the openings such as vehicle window and car door, and electromagnetic radiation is not only
Endanger the health of operating personnel, and the electronic equipment of cabin interior and instrument and meter also can caused by electromagnetic interference letter
Breath distortion, control failure, are unable to operate normally machinery.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of engineering machine with electro-magnetic screen function
Tool driver's cabin.
The present invention includes vehicle body, and car door is set on vehicle body, fixed window frame is set on car door, is set on fixed window frame

Effect, shield effectiveness >=20dB.
Feature of the present invention second is that：The first metal card slot of the movable window frame of setting direction on fixed window frame, in the first gold medal
Belong to the first conductive seal item of setting and movable window frame cooperation in card slot.
In order to reach sealing, conventional design is to be provided with sealing joint strip between fixed window frame and movable window frame.Due to
Conventional seals adhesive tape is rubber material, therefore without conducting function, electromagnetic wave remains to enter in driver's cabin at window.And this hair
Bright to use conductive seal item, the material of conductive seal item is the silicon rubber containing nickel carbonaceous conductive glue, by being made with steel plate materials
Metal card slot conductive seal item is fixed, make active window close after, between movable window frame and car door formed be electrically connected, with
Reach the part and have shielded effect.
The three of feature of the present invention are：The second metal card slot towards vehicle body is set on car door, in the second metal card slot
Second conductive seal item of setting and vehicle body cooperation.
Car door and vehicle body are electrically conductive made of steel plate materials, but since common car door sealing rubber strip does not have conduction
Function, electromagnetic wave remain to enter in driver's cabin at car door.
The present invention is formed electrically continuous using conductive seal item after making closing of the door, between car door and vehicle body.
In order to ensure the conductive effect of each conductive seal item, between the first conductive seal surface any part 1cm
Resistance≤1 Ω, the second conductive seal surface any part 1cm between the Ω of resistance≤1.
The four of the features of the present invention are：It is related to conductive position on the conductive plate, movable window frame, metal card slot and vehicle body
Spray conductive coating.
To reach requirement for anticorrosion, the steel sheet component surface of driver's cabin needs spray paint, does not have and can reach due to commonly painting
To the electric conductivity of shielding requirements, therefore electric connection can not be formed between above-mentioned each component, and it is of the invention for being related to conductive position,
Conductive paint, the common paint of remaining position spraying are sprayed in metal surface.It is 35% to have content in conductive paint of the present invention
Nickel carbonaceous conductive particle, can realize the electric connection between each associated components.Specific spraying position and effect are as follows：
The first conductive coating is set in the conductive plate surface towards shield glass, the shielding glass being bonded therewith by conductive plate realization
Electric connection between glass and movable window frame.

Electric connection.
Third conductive coating is set in the first metal card rooved face, to realize the first metal card slot and the first conductive seal item
Between electric connection.
The 4th conductive coating is set in the activity sash frame surface towards the first conductive seal article, with realization activity window frame and the
Electric connection between one conductive seal item.
The 5th conductive coating is set on the surface that vehicle body is contacted with the second conductive seal article, to realize vehicle body and the second conduction
Electric connection between sealing strip.
The 6th conductive coating is set in the second metal card rooved face towards the second conductive seal article, to realize the second metal
Being electrically connected between card slot and the second conductive seal item.
The Ω of resistance between above each conductive coating surface any part 1cm≤1, it is ensured that sufficiently small resistance, to reach
Preferable electric conductivity.
The present invention makes to be formed between the vehicle body of glass, active window, car door and driver's cabin to be electrically connected by more than conductive structure
Continuous, similarly, other openings of driver's cabin can also make driver's cabin integrally have electromagnetic shielding work(with reference to this structure design
Energy.
The advantageous effect of patent of the present invention is：It is rational in infrastructure, dependable performance, easy to implement.The present invention using shield glass,
