Description

Technical Field

[0001] This utility model belongs to the technical field of intelligent electric bicycle accessories, specifically, it relates to a high-capacity intelligent electric assist bicycle frame battery assembly. Background Technology

[0002] Smart electric-assist bicycles are electric bicycles that provide assistance during riding. Their battery packs are typically installed in the seatpost, specifically in the slanted tube connecting the handlebars and sprocket. To reduce weight and save space, the battery capacity is also reduced, resulting in an overall elongated tubular design suitable only for short-distance riding. If a larger battery capacity is needed, the battery pack size would increase, making it impossible to install in the seatpost. Installing it in other locations would make disassembly and charging inconvenient, contradicting the design principles of electric-assist bicycles.

[0003] Therefore, the design of a high-capacity intelligent electric-assist bicycle frame battery assembly urgently needs to be studied. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide a high-capacity intelligent electric-assist bicycle frame battery assembly, which avoids the trouble caused by the inability to install large-capacity battery packs in the frame of electric-assist bicycles in the past, resulting in difficulties in disassembly and assembly.

[0005] To address the aforementioned technical problems, this utility model discloses a high-capacity intelligent electric-assist bicycle frame battery assembly, comprising:

[0006] The frame tube assembly includes a seat tube, with a rear seat tube and a front slant tube welded to its two ends respectively. The rear seat tube is used to connect to the seat, and the front slant tube is used to connect to the handlebars.

[0007] The power connector is located on the upper surface of the lower seat tube;

[0008] A guide base plate fixed to the upper surface of the lower seat tube and exposing the power connection pins; the guide base plate has a front guide protrusion, a middle guide shaft groove, and a rear guide groove.

[0009] The battery box is installed on the upper side of the lower seat tube, and the bottom of the battery box is fitted with the power connection pin and the guide base plate.

[0010] Two limiting posts are set inside the front inclined tube, with the limiting posts facing the battery box and a lock hole at the top. The battery box has a limiting groove corresponding to the limiting post and a lock corresponding to the lock hole.

[0011] The clamp is located inside the rear riser, facing the battery box, and the battery box has a corresponding protruding latch.

[0012] According to one embodiment of the present invention, an upper horizontal tube is welded between the rear vertical tube and the front inclined tube, and the upper horizontal tube is located at the upper end of the battery box.

[0013] According to one embodiment of the present invention, the aforementioned limiting posts are circular and spaced apart, and the limiting groove has a circular groove portion located at the center of the side of the battery box and an expanded groove portion extending outward from the circular groove portion.

[0014] According to one embodiment of the present invention, the clamps have slots corresponding to protruding buckles.

[0015] According to one embodiment of the present invention, the battery box is provided with a carrying handle at the upper end.

[0016] According to one embodiment of the present invention, the rear end of the lower seat tube is further provided with two lower fork interfaces, which are connected to the lower forks on the left and right sides of the rear wheel.

[0017] According to one embodiment of the present invention, the bottom of the battery box is provided with a power connector corresponding to the power connector pins, which respectively correspond to the front positioning groove, the middle positioning shaft, and the rear positioning protrusion of the front guide protrusion, the middle guide shaft groove, and the rear guide groove.

[0018] Compared with the prior art, the present invention can achieve the following technical effects:

[0019] By housing the battery box in the center of the frame tube assembly, the bottom seat tube is connected to the power connector and guide base plate for bottom docking. At the same time, the clamps, locking holes, and limit posts of the rear seat tube and front slant tube form a front and rear locking, completing the assembly of the entire large-capacity battery box. The space arrangement is increased, the size is larger than that of the tubular battery pack, the riding range is improved, and the installation and disassembly are convenient.
