[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0023] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: an electric bicycle frame, including a base 3. The front end of the base 3 is obliquely upwardly connected to an upper cross beam 1. The other end of the upper cross beam 1 is fixed with a head 2 for connecting to a front fork. The rear end of the base 3 is obliquely upwardly connected to a seat tube 4, and a seat is connected to the seat tube 4. The rear end of the base 3 is also connected to a lower fork 7 for connecting to the rear wheel of the bicycle. The interior of the lower fork 7 is hollow to facilitate passing the brake cable through the lower fork 7 to connect to the rear wheel. An upper fork 6 is connected between the lower fork 7 and the seat tube 4. The lower fork 7 enhances the connection strength between the lower fork 7 and the seat tube 4, further enhancing the rigidity of the lower fork 7. A battery compartment is formed inside the upper cross beam 1 for installing a battery. The base 3 is communicated with the battery compartment to facilitate connecting the battery to the motor inside the base 3 to provide power for the motor. A battery 13 is buckled in the battery compartment. A wiring partition 12 is formed on the bottom surface of the battery compartment. A wiring groove 14 is formed between the wiring partition 12 and the bottom surface of the battery compartment. By passing the connecting wire of the battery 13 into the wiring groove 14 and extending it into the base 3 to connect to the motor inside the base 3 to provide power for the motor, and the formation of the wiring groove 14 makes wiring more convenient, avoiding extrusion and friction between the battery 13 and the circuit. The connecting wire of the battery 13 and the brake cable of the bicycle are all arranged in the wiring groove 14, avoiding the wires being exposed outside the frame, improving the aesthetics, and at the same time better protecting the circuit, reducing damage to the circuit, and extending the service life.

[0024] As Figure 3 and 4 shown, the wiring partition 12 includes a partition body 122. First corner flanges 121 and second corner flanges 124 are formed at both ends of the partition body 122 on the inner wall of the upper cross beam 1. The settings of the first corner flanges 121 and the second corner flanges 124 increase the distance between the partition body 122 and the inner wall of the upper cross beam 1, further expanding the space of the wiring groove 14 and making wire threading more convenient and smooth.

[0025] An arc-shaped groove 123 is formed on the inner wall of the partition body 122. The arc-shaped groove 123 further expands the space of the wiring groove 14, reducing the extrusion and friction of the obliquely arranged partition body 122 on the circuit.

[0026] As Figure 5As shown in the figure, a top support 11 is formed on the top wall of the upper crossbeam 1. The top support 11 is used to connect the battery interface and the battery lock. The top support 11 includes a support fork 111. A central hole 112 is formed in the center of the support fork 111. Two fasteners respectively pass through the central holes 112 at both ends on the top wall of the upper crossbeam 1. The fasteners connect the top support 11 to the battery interface and also connect the top support 11 to the battery lock, thus facilitating the installation of the battery 13 and locking the battery in the battery compartment by using the battery lock.

[0027] A sleeve 5 is connected to the rear of the seat tube 4. The sleeve 5 communicates with the base 3. Wiring is convenient inside the sleeve 5 to connect the taillight to the battery 13 and provide power for the taillight.

[0028] A taillight mounting seat 51 is connected to the rear of the sleeve 5. The taillight is mounted under the rear side of the seat through the taillight mounting seat 51.

[0029] A QR code mounting plate 8 is also fixed between the upper forks 6. The QR code is fixed through the QR code mounting plate 8.

[0030] A headlight mounting seat 21 and a basket mounting seat 22 are also fixed on the head 2. The basket mounting seat 22 is located on the headlight mounting seat 21. The headlight and the basket are respectively mounted through the headlight mounting seat 21 and the basket mounting seat 22.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
