The invention discloses an automatic locking charging base, a charging device and a motor vehicle. The charging base comprises a base body, a terminal and a locking mechanism; the base body is provided with at least one terminal cylinder, the terminal is provided with an insertion section with a variable diameter, at least parts of the insertion section is arranged in the terminal cylinder, and an insertion cavity is formed in the insertion section; the locking mechanism is at least partially arranged at the periphery of the insertion section and is configured to translate along the axial direction of the terminal and reduce or enlarge the diameter of the insertion cavity. According to the automatic locking charging base, the female terminal can be automatically locked when the male terminal and the female terminal are plugged, so that the contact area when the female terminal and the male terminal are plugged is ensured, the contact resistance of a plug-in structure is reduced, and the risks of part damage and even vehicle burnout caused by too high temperature rise of the plug-in structure are reduced.

    本发明公开了一种自动锁紧的充电座、充电装置及机动车辆,充电座包括座体、端子和锁紧机构,座体上设有至少一个端子筒,端子具有直径变化的插入段,插入段的至少部分设置在端子筒内部,插入段内部形成插入腔体,锁紧机构至少部分设置在插入段外周,并构造成沿端子轴向方向平移并使插入腔体的直径缩小或扩大。本发明的自动锁紧的充电座,可以在公端子与母端子对插时使母端子自动锁紧,保证母端子与公端子对插时的接触面积,降低对插结构的接触电阻,减少由于对插结构温升过高产生的零部件损坏甚至车辆烧毁的风险。
