[Prior Art] Taiwan Patent No. M258916 discloses a "battery seat structure for electric bicycles", which is mainly after the battery case is mounted in the frame, and then positioned by the movable fastener to enable the battery case to be attached to the activity buckle. The conductive sheets are electrically connected within the piece. However, in the above patent case, after the battery case is mounted on the frame, only the movable fastener is used for positioning, and no fixed structure is provided between the battery case and the frame. Therefore, the battery case may be moved by the movable fastener during the driving process of the electric bicycle. The swaying effect is insufficient and the swaying is caused. For a long time, it will easily cause damage to the f-pool box. SUMMARY OF THE INVENTION The main object of the present invention is to provide a battery for an electric bicycle ("" In order to achieve the above object, the battery pack assembly of the present invention comprises a frame power control box, a battery case, and a fixing device. The power control device sighs in the frame and has two first limiting portions; the battery case has a limiting portion' and the two second limiting portions are detachably connected to the '- cousin of the power control box a limiting portion, wherein the battery case is fixed to the power control 201128365 box' at the same time to form an electrical connection; the fixed-fixing member and the mounting member are detachably connected to the first member of the battery disposed on the frame Solid: the solid part, the second is fixed to the frame. Connected to the battery box to fix the hook-shaped guide groove, the first-limit portion of the electric second box is such that the guide block can slide the guide block in the guide groove - the aspect a torque; = the end of the channel. The other fixing member holds 4:=:= the second fixing member and the first-through-linking member forcibly rotate the second solid two-wheeled key. The present invention is directed to providing an electrical=forming mounting method that allows the battery case to be mounted after installation. To achieve the above object, the mounting method of the present invention first provides a frame, a power control box, a battery case, and a fixing device (1), the power control box is fixed to the miscellaneous frame, and has two first-limit portions, the battery case has two second limiting portions, and the turning device has a a first fixing member and a second fixing member pivoted to the battery case, and then the first limiting portion of the battery is respectively engaged with the power control, and the first limiting portion The battery case fixes the power control box, and at the same time forms an electrical connection, and finally presses the battery case downward in the direction of the frame, so that the fixed fixing second fixing member is fixed to the first fixing member for Battery = 201128365 is fixed to the frame. In the embodiment of the present invention, the first limiting portion of the power control box is a curved hook-shaped guiding slot, and the second limiting portion of the battery box is a half-moon shaped guiding block, so that the rear end of the battery box needs a slight Raise it obliquely to slide the guide block of the battery JHL into the guide groove of the power control box' and then push the battery case to engage the guide block of the battery case to the end of the guide groove of the power control box. On the other hand, after the battery case is pressed down toward the frame, the second fixing member is pivoted until the second hook portion of the second fixing member is offset from the first hook portion of the first fixing member. At the same time, the second fixing member is subjected to a torsion spring to cause the second hook portion of the second fixing member to be hooked to the first hook portion of the first fixing member. Thus, the battery pack assembly of the present invention allows the battery case to be simultaneously fixed to the power control box and the frame to obtain a stable mounting effect, and indeed achieves the object of the present invention.
