Description

Technical Field

[0001] The present invention relates to the field of charging structures, and in particular to a charging structure with a fool-proof function. Background Art

[0002] With the increasing popularity of electric vehicles and the continuous advancement of technology, electric vehicle charging technology has also made great progress. However, in actual application, traditional electric vehicle charging plugs and battery structures have some obvious defects, especially the proneness to errors during the docking and charging process, which not only affects charging efficiency but also may pose safety risks.

[0003] Currently, during the actual use of electric vehicles, the original charger may be damaged or users may want a charger with higher power. Some users may choose not to buy the original charger and choose to use other models of chargers circulating on the market. When using other models of chargers circulating on the market, it is easy to connect the positive and negative poles of the male and female ends in reverse, causing safety accidents such as short circuit and fire of the battery pack protection board, posing a threat to personal safety and property safety. Summary of the Invention

[0004] In order to reduce the possibility of users misusing non-original charging plugs and improve usage safety, the present application provides a charging structure with an anti-fouling function.

[0005] The present application provides a charging structure with foolproof function, which adopts the following technical solutions:

[0006] A charging structure with an anti-foolproof function comprises a male end for electrically connecting to the charging end of a charger and a female end for electrically connecting to the charging end of an electric vehicle, the male end being equipped with a plug connector, and the female end being provided with a plug slot for inserting the plug connector; the plug connector being provided with a plurality of plug holes, the plug connector being provided with a power-on plug post located in the plug holes; the plug slot being provided with a plug post for plugging into the plug hole, the plug post being provided with a power-on slot for inserting the power-on plug post, the outer side wall of the plug connector being provided with a plurality of anti-foolproof plug blocks at intervals along the circumferential direction, and the spacing between adjacent anti-foolproof plug blocks being different; the inner side wall of the plug slot being provided with an anti-foolproof slot matching the anti-foolproof plug post along the circumferential direction.

[0007] By adopting the above technical solution, when charging is needed, when the plug connector is inserted into the socket, the anti-middle plug block is inserted into the anti-middle slot, the plug post is inserted into the socket hole, and the power plug post is inserted into the power slot. Since the spacing between multiple anti-middle plug blocks is different, users can only use the original charging plug to charge the electric vehicle, thereby achieving an anti-middle effect, reducing the risk of users connecting the male end of the charger circulating on the market with the positive and negative poles of the original female end of the electric vehicle in reverse, and improving safety of use.

[0008] Preferably, two pairs of anti-foolproof plug blocks are provided, and the cross-sectional shapes of the two pairs of anti-foolproof plug blocks are different.

[0009] By adopting the above technical solution, the fool-proofing action of each fool-proof plug block can be achieved, thereby improving the plug-in accuracy between the male end and the female end.

[0010] Preferably, each corner of each fool-proof plug-in block is arc-shaped.

[0011] By adopting the above technical solution, a guiding effect is achieved and the smoothness of plugging is improved.

[0012] Preferably, the plug-in post includes a first unit and a pair of second units, the powered plug-in post includes a negative pole, a positive pole and a ground pole, the ground pole is inserted into the plug-in post through the powered slot of the first unit, the positive pole is inserted into the plug-in post through the powered slot of one second unit, and the negative pole is inserted into the plug-in post through the powered slot of another second unit; the cross-section of the first unit and the cross-section of the second unit are different polygons.

[0013] By adopting the above technical solution and using a variety of different plug-in posts to insert into the plug-in holes, the compatibility between the original male end and the female end is further improved, and the possibility of a non-original male end being plugged into the original female end is reduced, thereby further improving safety.

[0014] Preferably, the two second units are symmetrically arranged along the radial direction of the plug-in slot.

[0015] By adopting the above technical solution, the two second units are reasonably arranged in the plug-in slot, the space occupied by the two second units is reduced, and the volume required for the plug-in slot is reduced, thereby improving the space utilization rate of the plug-in slot installed at the rear of the electric vehicle.

[0016] Preferably, a pair of the anti-idiot plug-ins are located on one side of the plug connector where the grounding column is set, and the other pair of the anti-idiot plug-ins are located on the other side of the plug connector; the two plug-in holes adapted to the two second monomers are symmetrical holes, and the two anti-idiot plug-ins in each pair are symmetrically arranged toward the symmetry axis of the two symmetrical holes.

[0017] By adopting the above technical solution, the overall structure can be made more symmetrical, making the overall appearance more neat. While ensuring that mis-insertion is avoided, the overall structure has regularity, thereby improving ease of use.

[0018] Preferably, the outer side wall of the male end is provided with anti-slip grooves.

[0019] By adopting the above technical solution, the friction between the hand and the male end when the user grasps the male end can be improved, the slippage during plugging can be reduced, and the plugging smoothness can be improved.

[0020] Preferably, the outer side wall of the female end is provided with an external thread for connecting to an electric vehicle.

[0021] By adopting the above technical solution, the installation of the female end is facilitated and the installation is stable.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When charging is required, the plug connector is inserted into the socket, the anti-mashup plug is inserted into the anti-mashup slot, the plug post is inserted into the plug hole, and the power plug is inserted into the power slot. Since the spacing between the multiple anti-mashup plugs is different, the user can only use the original charging plug to charge the electric vehicle, achieving an anti-mashup effect, reducing the user's misuse of non-original charging plugs, and improving safety;

[0024] 2. It can achieve the anti-fool action between each anti-fool plug and improve the plug-in accuracy between the male end and the female end;

[0025] 3. Using a variety of different plug-in posts to insert into the plug-in holes further improves the adaptability between the original male end and the female end, reduces the possibility of non-original male end being plugged into the original female end, and thus further improves safety.
