[0012] The beneficial effects of the present utility model:
[0013] 1. Compared with the traditional electric vehicle charging interface, which uses a common triangular interface and has a poor anti-fooling effect and cannot distinguish chargers with different charging methods. When using a 60V charger to charge an electric vehicle powered by a 48V battery, it is easy for the electric vehicle battery to malfunction or even catch fire due to overcharging, affecting the safety of users and the public. By adding an anti-fooling structure to the interface, this device distinguishes different chargers, preventing users from using the wrong charger to charge the electric vehicle and ensuring the safety of the electric vehicle battery;
[0014] 2. When charging by connection, insert the insertion base into the fixed base. The anti-slip pattern prevents the hand from sliding against the insertion base. The cross-sections of the anti-fooling special-shaped block and the anti-fooling special-shaped hole match, and the cross-sections of the anti-fooling post and the anti-fooling hole match, enabling the insertion base to continue moving. Insert the electrode into the charging hole for charging. The charging hole can also isolate multiple groups of electrodes to prevent short circuits when water enters. When using the wrong charger, the cross-sections of the anti-fooling post and the anti-fooling hole do not match, and the cross-sections of the anti-fooling special-shaped block and the anti-fooling special-shaped hole do not match, making it difficult to insert the insertion base into the fixed base, achieving the anti-fooling function, so as to solve the problem that the anti-fooling effect of most electric vehicle charging interfaces is poor and users are prone to using the wrong charger for charging.
[0015] 3. The installation post installs and fixes the nameplate to display the parameters of the charger to the user, facilitating the user to find a suitable charger. When the insertion base is inserted, lift the cover plate, drive the connecting block to make the rotating rod rotate in the rotating seat, and at the same time store energy for the torsion spring. During the movement of the insertion base, the buckle slides on one side of the insertion base. After the insertion base moves to the appropriate position, the torsion spring releases energy to drive the cover plate to move, so that the buckle snaps into one side of the insertion base, preventing the insertion base from sliding out during charging, causing poor contact between the electrode and the charging hole, and at the same time facilitating the user to know whether the insertion base is inserted in place.
