Description
Technical field
The present invention relates to charging pile, specifically refer to charging pile plug wire mouth structure.
background technologyenvironmental pollution, energy scarcity just day by day become China's sustainable development and build a Harmonious Society must faced by severe problem, in order to tackle above-mentioned challenge, green, environmental protection, energy-conservationly become the popular topic of society.Government is in order to improve the quality of development, and also actively encourage every profession and trade development energy saving environmental protection product, therefore, environmental protection and energy saving product is filled with vigor at society, is the new driving source of economic growth.Electric motor car is as a kind of green traffic instrument of effective replacing fuel oil automobile, and no matter from environmental angle or energy angle, following electric motor car all needs a large development.
In the face of the electric motor car of One's name is legion, the lead-acid battery adopted because of it or lithium battery cause its flying power extremely to be limited to, usually in traveling once charging to three days, and often occur in because of the phenomenon that electric power is carried out not and by electric motor car on highway, so charging pile for electric vehicle arises at the historic moment.But the electric motor car of current nearly all community charging does not all have the charging place of specification, substantially be charged to Stall by every family Jia Zhongcong building exterior wall unwrapping wire, private is drawn and is disorderly connect, and cause the safe and reliable degree of electric power greatly to reduce, security incident rate increases thereupon; And the impact that existing outdoor charging pile is subject to outside environmental elements is comparatively serious, usually there will be into water or a large amount of dust on rainy day or the interface of special road section place charging pile, cause reduce the useful life of charging pile, charging pile short circuit time serious, can be caused even directly to damage.
Summary of the invention
The object of the present invention is to provide charging pile plug wire mouth structure, ensure the fail safe that charging pile interface uses, avoid the foreign material such as rainwater or dust to enter in charging inlet.
Object of the present invention is achieved through the following technical solutions:
Charging pile plug wire mouth structure, comprise the housing that covers charging inlet place and rotation and be arranged on curved cover plate on housing, clip-connecting rod is fixed with at the two ends of described cover plate, baffle plate is provided with bottom the movable end of cover plate, on housing, correspondence is provided with the clamping seat matched with clip-connecting rod and the guide vane end stop that can match with baffle plate, described guide vane end stop has dovetail groove, the middle part of dovetail groove is fixed with tapered pole, it is trapezoidal flexible feet that the end of described baffle plate is provided with two cross sections, and forms a cavity matched with tapered pole between two flexible feets; Also comprise two acute angle corner blocks, the longest edge of two described acute angle corner blocks is connected with the two side of dovetail groove respectively, when cover plate seals charging inlet, the position of baffle plate and dovetail groove is configured to, flexible feet enters its outer wall after in dovetail groove and does relative motion with the hypotenuse of acute angle corner block, while two flexible feets extruding of being subject to two acute angle corner blocks respectively draw close to tapered pole.
After electric motor car charging is complete, cover plate is pressed down, makes it be covered completely by whole charging inlet, clip-connecting rod and clamping seat are cooperatively interacted, and then it is airtight to prevent extraneous dust or rainwater enters into charging inlet to complete charging inlet, ensures that the stability of charging pile uses, when the present invention works, when cover plate seals charging inlet, the position of baffle plate and dovetail groove is configured to, the hypotenuse that flexible feet enters its outer wall and acute angle corner block after in dovetail groove does relative motion, and the inwall of cavity glides along tapered pole outer wall, for the movement of cavity provides guide effect, the extruding that simultaneously two flexible feets are subject to two acute angle corner blocks is respectively drawn close to tapered pole, self can reply deformation after there is deformation after flexible feet is squeezed and then a rightabout active force is produced to acute triangle, baffle plate is made to be clamped in dovetail groove, make cover plate locked at charging inlet place, prevent the children near charging pile from wantonly being opened by cover plate because playing, avoid occurring electric power safety accident, improve the fail safe of charging pile.
Further, the cross section of described cavity is trapezoidal, and the smallest end external diameter of tapered pole is greater than the smallest end internal diameter of cavity.Cavity along tapered pole outer wall glide time, the overall dimensions of tapered pole is greater than the space size of inside cavity, and then the space of inside cavity is swollen by the tapered pole when flexible feet moves down, and then a direction is produced to flexible feet with acute angle corner block, the contrary pressure of force direction is produced to flexible feet, make flexible feet by stable holding in dovetail groove, ensure that cover plate is to the sealing property of charging inlet.
Further, also comprise drainage, described drainage is arranged on the bottom of housing, and just to the center of baffle plate.Have when rainy day or roadside vehicle travel by liquid splash to cover plate time, baffle plate and guide vane end stop drain into housing bottom by under rainwater, finally by drainage outflow charging pile, avoid rainwater flow to charging inlet place and cause the short circuit of charging pile impaired.
The present invention compared with prior art, has following advantage and beneficial effect:
1, the present invention is when cover plate seals charging inlet, the position of baffle plate and dovetail groove is configured to, the hypotenuse that flexible feet enters its outer wall and acute angle corner block after in dovetail groove does relative motion, and the inwall of cavity glides along tapered pole outer wall, for the movement of cavity provides guide effect, the extruding that simultaneously two flexible feets are subject to two acute angle corner blocks is respectively drawn close to tapered pole, self can reply deformation after there is deformation after flexible feet is squeezed and then a rightabout active force is produced to acute triangle, baffle plate is made to be clamped in dovetail groove, make cover plate locked at charging inlet place, prevent the children near charging pile from wantonly being opened by cover plate because playing, avoid occurring electric power safety accident, improve the fail safe of charging pile,
2, the present invention cavity along tapered pole outer wall glide time, the overall dimensions of tapered pole is greater than the space size of inside cavity, and then the space of inside cavity is swollen by the tapered pole when flexible feet moves down, and then a direction is produced to flexible feet with acute angle corner block, the contrary pressure of force direction is produced to flexible feet, make flexible feet by stable holding in dovetail groove, ensure that cover plate is to the sealing property of charging inlet.
