The invention provides an electric bicycle frame, an electric bicycle, a battery box body and a battery. The electric bicycle frame comprises: a first mounting rod; a second mounting rod; and a bottom support. A guide rail extending up and down is arranged on the first mounting rod and the second mounting rod and is used for being in up-down guide fit with guide grooves in the side wall of the battery box body; the guide rail is provided with a clamping groove for a telescopic rod on the battery box body to be clamped in so as to limit the battery box body. The battery box body comprises a first side wall, a second side wall, a third side wall and a fourth side wall, the first side wall and the second side wall are parallel, guide grooves extending up and down are formed in the first side wall and the second side wall, telescopic rods are arranged on the guide grooves, and the telescopic rods are used for being clamped into clamping grooves in an electric bicycle frame so as to lock the battery box body. An unlocking mechanism for driving the telescopic rods to move for unlocking is mounted on the battery box body. According to the invention, a relatively good anti-theft effect can be achieved on the battery box body, and the battery box body can be conveniently taken out when charging is needed.

    本发明提供了一种电动自行车车架、电动自行车、电池箱体及电池,电动自行车车架包括:第一安装杆;第二安装杆;底部支撑件;第一安装杆和第二安装杆上设有上下延伸的导轨,导轨用于与电池箱体侧壁上的导槽上下导向配合;导轨上设置有供电池箱体上的伸缩杆卡入的卡槽,以对电池箱体进行限位。电池箱体包括平行的第一侧壁和第二侧壁、平行的第三侧壁和第四侧壁,第一侧壁和第二侧壁中上设置有上下延伸的导槽,导槽上设置有伸缩杆,伸缩杆用于卡入电动自行车车架上的卡槽中,以将电池箱体锁死,且电池箱体上安装有用于驱动伸缩杆移动以进行解锁的解锁机构。本发明能够对电池箱体起到比较好的防盗效果,且方便在需要充电时将电池箱体取出。
