The invention provides a charging interface structure. The charging interface structure comprises an inner contact mounting plate; at least two inner contacts which are arranged on the inner contact mounting plate and are communicated with an internal circuit of the charging equipment; an outer contact mounting plate; at least two outer contacts which are arranged on the outer contact mounting plate, are communicated with a charging plug of an external circuit and are in one-to-one correspondence with the inner contacts, wherein a certain insulation distance is formed between the correspondingouter contact and the corresponding inner contact; a connecting sleeve, wherein one end of the connecting sleeve is connected to the edge of the charging interface, the other end of the connecting sleeve is connected to the outer contact mounting plate, and the connecting sleeve and the outer contact mounting plate define an inserting cavity for inserting a charging plug; wherein the connecting sleeve and/or the outer contact mounting plate are/is made of an elastic material. The invention has the beneficial effects that when no charging is performed, the inner contact is isolated from the outside, even if water enters the charging interface and the plugging cavity, the positive electrode inner contact and the negative electrode inner contact cannot be conducted, so the short-circuit fault of an internal circuit is avoided, the waterproof effect is achieved, the outer contact is not electrified, and the safety is greatly improved.
本发明提供了一种充电接口结构,包括:内触点安装板;内触点,有至少两个,设在内触点安装板上,与充电类设备的内部电路连通;外触点安装板;外触点,设在外触点安装板上,与外部电路的充电插头连通,有至少两个且与内触点一一对应,对应的外触点与内触点之间具有一定的绝缘距离;连接套,一端连在充电接口口沿处、另一端连在外触点安装板上,连接套和外触点安装板围成供充电插头插入的插接腔;连接套和/或外触点安装板由弹性材料制成。有益效果:未充电时,内触点与外界隔绝开,即使有水进入充电接口内,也是进入插接腔中,不会将正极和负极内触点导通,避免内部电路发生短路故障,达到了防水的效果,并且外触点不带电,大大提高了安全性。
