Description
Technical field
The utility model relates to the improvement proposed the charging socket of electric automobile.
Background technology
At present, for guaranteeing fail safe during charging electric vehicle, usually coupling assembling need be set at plug (socket) place.To this, the applicant once on June 12nd, 2012 applied for a " the charging plug device of electric automobile " by name, application number is the patent of " 201220275844.3 ", and in this case, proposes a kind of novel plug device.But find after reality uses, its less stable, connection reliability are lower, easily produce " slippage " phenomenon, bring great impact to the charging of electric automobile, and bring certain potential safety hazard during use.
Utility model content
The utility model, for above problem, proposes that a kind of novel structure, connection reliability are high, not easily slippage and the charging socket assembly of the high electric automobile of fail safe.
The technical solution of the utility model is: comprise the charging plug being fixedly connected on cradle on electric automobile and external power supply, the end face of described charging plug offers accommodating heavy stand and is provided with some lock pins in heavy stand; The end face of described cradle offers the storage tank with described charging plug adaptation, offer the cylindrical bump with described accommodating heavy stand adaptation in described storage tank, the end face of described cylindrical bump offers the slot with described lock pin adaptation;
Described cradle is also equipped with at least one alignment pin, described alignment pin arranges along the radial direction of described cradle and stretches in described storage tank, described alignment pin is wedge shape towards the side of the notch of described storage tank, and the outside of described alignment pin is fixedly connected with end cap and the outer wall bracket of described end cap and described cradle is connected with extension spring;
The outer wall of described charging plug offers the annular recess for accommodating described alignment pin and described charging plug is also socketed with triggering swivel nut outward, described triggering swivel nut is threaded connection on the outer wall of described charging plug, described triggering swivel nut is conical surface shape towards being provided with gap between the side and the outer wall of charging plug of described accommodating heavy stand and triggering swivel nut towards the side of described accommodating heavy stand, and the side of described triggering swivel nut can be stretched between end cap and the outer wall of cradle.
The radius of the radius sum >=described cradle of described gap and charging plug.
Described cradle is equipped with some alignment pins, and some described alignment pins are evenly distributed on the same shaft section of described cradle.
When the utility model uses, can directly insert in the storage tank of cradle by charging plug, after completing grafting, alignment pin stretches under the effect of extension spring in the annular recess of charging plug downwards, thus effective " pinning " charging plug.And when pulling up charging plug, then can triggering swivel nut be screwed between end cap and the outer wall of cradle, thus lift alignment pin, and then charging plug can conveniently be extracted.Have that novel structure, connection reliability are high, not easily slippage and the high feature of fail safe.
Accompanying drawing explanation
Fig. 1 is using state reference diagram of the present utility model,
Fig. 2 is the structural representation of charging plug in the utility model;
In figure, 1 is cradle, and 11 is slots, and 12 is storage tanks, and 2 is charging plugs, and 21 is lock pins, and 22 is annular recess, and 3 is alignment pins, and 4 is end caps, and 5 is extension springs, and 6 is trigger swivel nut.
Embodiment
The utility model as shown in Figure 1-2, comprises the charging plug 2 being fixedly connected on cradle 1 on electric automobile and external power supply, the end face of described charging plug 2 offers accommodating heavy stand and is provided with some lock pins 21 in heavy stand; The end face of described cradle 1 offers the storage tank 12 with described charging plug adaptation, offer the cylindrical bump with described accommodating heavy stand adaptation in described storage tank, the end face of described cylindrical bump offers the slot 11 with described lock pin adaptation;
Described cradle 1 is also equipped with at least one alignment pin 3, described alignment pin 3 arranges along the radial direction of described cradle 1 and stretches in described storage tank 12, described alignment pin 3 is wedge shape towards the side of the notch of described storage tank 12, and the outside of described alignment pin 3 is fixedly connected with end cap 4 and described end cap 4 is connected with extension spring 5 with the outer wall bracket of described cradle 1;
The outer wall of described charging plug 2 offers the annular recess 22 for accommodating described alignment pin 3 and be also socketed with outside described charging plug 2 and trigger swivel nut 6, described triggering spiral shell 6 cover is threaded connection on the outer wall of described charging plug 2, described triggering swivel nut 6 is conical surface shape towards being provided with gap between the side and the outer wall of charging plug 2 of described accommodating heavy stand and triggering swivel nut 6 towards the side of described accommodating heavy stand, and the side of described triggering swivel nut 6 can be stretched between the outer wall of end cap 4 and cradle 1.
The radius of the radius sum >=described cradle 1 of described gap and charging plug 2.
Described cradle 1 is equipped with some alignment pins 3, and some described alignment pins 3 are evenly distributed on the same shaft section of described cradle 1.Thus the connection reliability improved further between charging plug and cradle, and then fail safe when significantly improving charging.
