Description
Technical field
The present invention relates to charging pile, in particular to a kind of wiring board shell structure.
Background technology
The electric car of current nearly all cell charges all without the charging place of specification, substantially by every family man
Zhong Cong buildings exterior wall unwrapping wire is charged to Stall, and private, which is drawn, disorderly to be connect, and causes the safe and reliable degree of electric power to substantially reduce, safe thing
Therefore rate increases therewith；And existing outdoor charging pile influenceed by outside environmental elements it is more serious, generally on rainy day
The interface of charging pile occurs that the service life for into water or a large amount of dusts, causing charging pile reduces at special road section,
Charging pile short circuit or even directly damage can be caused when serious.
The content of the invention
It is an object of the invention to provide a kind of wiring board shell structure, ensures the security that charging pile interface uses, keeps away
Exempt from the debris such as rainwater or dust to enter in charging inlet.
The purpose of the present invention is achieved through the following technical solutions：
A kind of wiring board shell structure, including it is covered in the housing at charging inlet and the arc being rotatably arranged on housing
Shape cover plate, clip-connecting rod is fixed with the both ends of the cover plate, the clip-connecting rod includes the cylinder and spheroid being connected with each other, cylinder
End and the movable end bottom of cover plate connect, and the movable end bottom of cover plate is provided with baffle plate, is correspondingly arranged on and blocks on housing
The clamping seat that post matches and the limited block that can be engaged with baffle plate are connect, is provided with the clamping seat for clamping column end activity
Spherical cavity, multiple fan grooves are offered on spherical cavity inwall, is slided in fan groove and is provided with grip block, and grip block leads to
The bottom for crossing spring and fan groove connects；It is trapezoidal flexible feet that the end of the baffle plate, which is provided with two sections, and two
Individual flexible feet leaves gap, and dovetail groove, in addition to two acute angle corner blocks, two acute angle corner blocks are provided with limited block
Longest edge be connected respectively with the two side of dovetail groove, when cover plate seals to charging inlet, baffle plate and dovetail groove
Position is configured as, and the hypotenuse of its outer wall and acute angle corner block does relative motion after flexible feet enters in dovetail groove, while two
Individual flexible feet is pressed against drawing close in the middle part of gap by two acute angle corner blocks respectively., will after electric car charging finishes
Cover plate pushes, and makes it that whole charging inlet to be completely covered so that clip-connecting rod cooperates with clamping seat, and then completes to charging
Interface it is closed with prevent the external world dust or rainwater enter in charging inlet, ensure charging pile stability use；This
During invention work, after cover plate is rotated down certain angle around the shaft, spheroid enter spherical cavity in, and the outer wall of spheroid with
The grip block contact of spherical cavity both sides, clip-connecting rod continue to move down, and grip block stress is moved in fan groove, while spring is pressed
Contracting, when spheroid enters spherical cavity bottom, spring is compressed into largest deformation amount, and one and folder can be produced when replying deformation
The opposite elastic force of block Impact direction is held, and then spheroid is fastened on spherical cavity, while baffle plate engages with limited block, is filled with realizing
It is complete closed at electrical interface；Wherein, the grip block stressing conditions positioned at spherical cavity bottom and the clamping of spherical cavity both sides
Block stressing conditions are identical, and in cover plate when pushing excessive velocities, the bottom of clip-connecting rod can occur acutely with spherical cavity bottom
Collision, and then cause both of which to be damaged, after spheroid is with the grip block upper surface positioned at spherical cavity bottom, spring pressure
The elastic force opposite with lower pressure direction is produced after contracting to buffer the impact that grip block is subject to, and then protection card joint chair internal junction
The purpose of structure；
When cover plate seals to charging inlet, the position of baffle plate and dovetail groove is configured as, and flexible feet enters swallow
The hypotenuse of its outer wall and acute angle corner block does relative motion after in stern notch, while two flexible feets are respectively by two acute angles three
Hornblock is pressed against drawing close in the middle part of gap, and flexible feet itself can reply deformation and then to acute angle after being deformed upon after being squeezed
Triangle produces the active force of an opposite direction so that baffle plate is clamped in dovetail groove so that cover plate quilt at charging inlet
Locking, prevents the children near charging pile from wantonly opening cover plate because playing, and avoids the occurrence of electric power safety accident, improves charging pile
Security.
Further, in addition to drainage, the drainage are arranged on the bottom of housing, and the center of face baffle plate.
When there is vehicle traveling in rainy day or roadside by liquid splash to cover plate, baffle plate will drain into housing bottom with limited block under rainwater
Portion, charging pile most is flowed out through drainage afterwards, avoids rainwater from flowing at charging inlet and cause the short circuit of charging pile to be damaged.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention is positioned at the grip block stressing conditions of spherical cavity bottom and the grip block stress feelings of spherical cavity both sides
Condition is identical, and in cover plate when pushing excessive velocities, violent collision can occur with spherical cavity bottom for the bottom of clip-connecting rod, and then
Cause both of which to be damaged, when clip-connecting rod end with positioned at spherical cavity bottom grip block upper surface after, spring pressure
The elastic force opposite with lower pressure direction is produced after contracting to buffer the impact that grip block is subject to, and then protection card joint chair internal junction
The purpose of structure；
2nd, when cover plate seals to charging inlet, the position of baffle plate and dovetail groove is configured as the present invention, elasticity branch
The hypotenuse of its outer wall and acute angle corner block does relative motion after pin enters in dovetail groove, while two flexible feets are respectively by two
Individual acute angle corner block is pressed against drawing close in the middle part of gap, and flexible feet itself can reply deformation after being deformed upon after being squeezed and enter
And the active force of an opposite direction is produced to acute triangle so that baffle plate is clamped in dovetail groove so that cover plate is charging
Interface is locked, and is prevented the children near charging pile from wantonly opening cover plate because playing, is avoided the occurrence of electric power safety accident, carry
The security of high charge stake.
