[0016] See also Figures 1-4, a built-in cable bin for an electric-assisted bicycle, comprising a cable bin 10 and a wire 11; the cable bin 10 is configured as a cylindrical structure and is opened in the frame of the electric-assisted bicycle, and structures such as a battery pack, a motor and a control system are installed inside the cable bin 10, and the specific distribution is determined according to actual installation requirements. The battery pack, the motor and the control system are electrically connected through the wire 11. At the same time, multiple groups of cable assemblies 12 are detachably installed at intervals along the axial direction of the cable bin 10. The cable assemblies 12 are used to classify and position the wires 11 distributed inside the cable bin 10. The cable assemblies 12 are configured as an annular structure and comprise multiple groups of curved cable plates 14. The curved cable plates 14 are detachably installed on the inner wall of the cable bin 10, and the two ends of adjacent curved cable plates 14 are spaced apart to form an annular structure and are installed on the inner wall of the cable bin 10. Two arc-shaped positioning grooves 24 are symmetrically provided on both sides of the inner side surface of the group of arc-shaped cable arranging plates 14 facing the center of the cable arranging bin 10. Two groups of arc-shaped positioning pressure plates 20 are swingably set on the arc-shaped cable arranging plates 14 where the two arc-shaped positioning pressure grooves 24 are close to each other. The arc-shaped positioning pressure plates 20 and the arc-shaped positioning pressure grooves 24 are elastically swingingly magnetically positioned. The arc-shaped positioning pressure plates 20 and the arc-shaped positioning pressure grooves 24 can be swung to fit together or separate. The wires 11 to be arranged and positioned are placed in the arc-shaped positioning pressure grooves 24 according to their types, and then the arc-shaped positioning pressure plates 20 are swung to press them between the arc-shaped positioning pressure plates 20 and the arc-shaped positioning pressure grooves 24. After the arc-shaped positioning pressure grooves 24 and the arc-shaped positioning pressure plates 20 are fitted together, the inner side of the cable arranging assembly 12 still forms a circular structure, which keeps the interior of the cable arranging bin 10 clean and tidy, thereby achieving effective cable positioning of the wires 11.

[0017] In the embodiment of the present invention, a bolt 15 is installed in the middle of the outer wall of the curved cable tray 14 away from the center of the cable tray 10. An internal threaded hole 13 is opened on the inner wall of the cable tray 10 corresponding to the bolt 15. The bolt 15 is threadedly connected in the internal threaded hole 13 to maintain the detachable connection between the curved cable tray 14 and the inner wall of the cable tray 10. The bolts 15 on the outer side of each group of curved cable trays 14 are the same, ensuring that after being threaded into the internal threaded hole 13, adjacent curved cable trays 14 can maintain an end-to-end spacing distribution, thereby forming a complete ring structure;

[0018] The inner surface of the arc-shaped positioning groove 24 is provided with a plurality of equally spaced wire positioning grooves 16 along its arc-shaped structure. An arc-shaped positioning pressure rod 17 is installed on the arc-shaped positioning pressure plate 20 corresponding to the wire positioning groove 16. The wire 11 is further positioned by the wire positioning groove 16 and then pressed by the arc-shaped positioning pressure rod 17. At the same time, a layer of insulating rubber layer is laid on the surface of the arc-shaped positioning groove 24 to reduce the pressure wear on the wire 11 and improve safety to a certain extent by using insulation.

[0019] The arc-shaped positioning pressure rod 17 is made of insulating rubber material, which ensures that the wire 11 is pressed and held while having a certain buffering effect, that is, reducing the pressure damage to the wire 11;

[0020] In one embodiment of the present invention, a magnetic block 18 is installed on one side of the end of the arc-shaped positioning pressure plate 20, and a magnetic groove 19 is opened on the inner wall of the arc-shaped positioning pressure groove 24 corresponding to the magnetic block 18. The magnetic block 18 is magnetically connected to the magnetic groove 19. When the arc-shaped positioning pressure plate 20 swings toward the arc-shaped positioning pressure groove 24, the magnetic connection between the magnetic block 18 and the magnetic groove 19 is utilized to maintain a stable distribution between the arc-shaped positioning pressure plate 20 and the arc-shaped positioning pressure groove 24.

[0021] A swing connecting plate 21 is installed at the end of the arc-shaped positioning pressure plate 20 facing the arc-shaped wiring board 14, and a swing plate groove 23 is opened on the arc-shaped wiring board 14 corresponding to the swing connecting plate 21. Swing shafts 22 are installed at both ends of the swing connecting plate 21 placed inside the swing plate groove 23. The ends of the swing shafts 22 are rotatably connected to the inner wall of the swing plate groove 23. At the same time, a clockwork spring (not shown in the figure) is wound around the swing connecting plate 21. When the clockwork spring is in a free state, the arc-shaped positioning pressure plate 20 is controlled to be in a fit state with the arc-shaped positioning groove 24. That is, after the wire 11 is placed on the arc-shaped positioning groove 24, the elastic action of the clockwork spring and the magnetic action of the magnetic block 18 and the magnetic groove 19 are used to keep the arc-shaped positioning pressure plate 20 pressing the wire 11 placed on the arc-shaped positioning groove 24 with a certain force, thereby stably positioning and arranging the wire 11.

[0022] The working principle of the present invention is: in the idle position of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in sequence between the electrical components. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process, and does not explain the electrical control. During operation, the battery pack, motor and other electrical components are installed and distributed inside the cable bin 10, and then electrically connected to each other through the wires 11. Then, according to the number and length of the wires 11, a corresponding number of cable assemblies 12 are installed inside the cable bin 10 in advance. The inner arc of the cable assembly 12 in the initial state The arc-shaped positioning pressure plate 20 and the corresponding arc-shaped positioning groove 24 are in a fitted distribution state. When the wires 11 are arranged and positioned, according to the initial distribution position of the wires 11, the arc-shaped positioning pressure plate 20 and the arc-shaped positioning groove 24 are swung to distribute the wires 11, and the wires 11 are classified and passed through the corresponding arc-shaped positioning groove 24. Then, under the magnetic action of the clockwork spring and the magnetic block 18 and the magnetic groove 19, the wires 11 are placed in the fitted position of the wire positioning groove 16 and the arc-shaped positioning pressure rod 17, and are pressed and positioned with a certain force. In this way, the wires 11 at various positions are positioned on the corresponding arc-shaped positioning groove 24, thereby keeping the wires 11 neatly arranged.

[0023] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
