[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] The present invention provides a cable guide sleeve for a scooter, comprising a sleeve body with a guide hole, the guide hole including a cavity, a first opening for the cable harness to pass through, and a second opening for the cable harness to exit. The cavity is located inside the sleeve body, the first opening is located at the top of the sleeve body and communicates with the top of the cavity, the second opening is located at the rear side of the sleeve body and communicates with the rear side of the cavity, an arc-shaped guide surface is provided on the front side of the cavity, the top of the arc-shaped guide surface is connected to the front side of the first opening, and the bottom of the arc-shaped guide surface is connected to the bottom of the second opening. A cable groove for the front brake cable to pass through is vertically provided on one side of the sleeve body.

[0006] In this solution, the wiring harness includes a rear brake cable and a data cable. The sleeve is inserted into the swivel tube that connects to the scooter handlebars. During the wiring process, the wiring harness is first inserted through the upper opening of the swivel tube. As the wiring harness moves downward, the bottom end of the wiring harness is inserted through the first opening. Then, after the bottom end of the wiring harness contacts the arc-shaped guide surface, it is guided by the arc-shaped guide surface to the second opening, and then extends outward through the swivel tube through the second opening. Next, the front brake cable is wired. The bottom end of the front brake cable is inserted through the upper opening of the swivel tube. During the wiring process of the front brake cable, the bottom end of the front brake cable is guided by the wire groove on one side of the sleeve and passes through the sleeve from top to bottom. The overall wiring process is convenient, quick, and efficient.

[0007] Preferably, the arc of the arc-shaped guide surface is a quarter circle.

[0008] Preferably, the outer edge of the first opening is provided with a first rounded corner structure.

[0009] Preferably, the outer edge of the second opening is provided with a second rounded corner structure.

[0010] The present invention provides a scooter handlebar assembly, comprising a scooter handlebar, a head tube, a pivot tube, and a cable sleeve for a scooter as described above. The scooter handlebar is connected to the top of the pivot tube. The head tube is sleeved on the outside of the pivot tube and its upper and lower ends are rotatably connected to the pivot tube via cup bearings. The head tube has a cable outlet hole communicating with a slanted tube connecting to the frame. The pivot tube has an installation hole on its rear side corresponding to the cable outlet hole for the sleeve to extend into. The sleeve is located inside the pivot tube and is detachably connected to the pivot tube.

[0011] Preferably, the sleeve body has a threaded hole on the front side, and the rotating shaft tube has a through hole corresponding to the threaded hole. A locking screw is provided in the through hole, and the threaded part of the screw is threadedly connected to the threaded hole.

[0012] Preferably, when the locking screw is tightened to the locked position, the front side of the sleeve abuts against the front side of the inner wall of the shaft tube, the nut part of the locking screw is located in the through hole, and the rear side of the sleeve fits against the mounting hole.

[0013] Preferably, the wire groove and the inner wall of the shaft tube on the corresponding side form a channel for the front brake cable to pass through.

[0014] Preferably, the cross-section of the wire groove is arc-shaped.

[0015] When installing the sleeve, first insert the sleeve into the shaft tube through the mounting hole, then insert the threaded part of the locking screw into the through hole, so that the threaded part of the locking screw is threadedly connected to the threaded hole on the front side of the sleeve. Then tighten the locking screw, so that the threaded part of the locking screw drives the sleeve forward through the threaded hole until the front side of the sleeve abuts against the front side of the inner wall of the shaft tube. At this time, the locking screw is engaged in the locking position, the nut part of the locking screw is located in the through hole, and the rear side of the sleeve fits against the mounting hole. The sleeve is now installed. At the same time, the wire groove and the corresponding side of the inner wall of the shaft tube form a channel for the front brake cable to pass through.

[0016] When threading is required, first insert the wire harness into the swivel tube, so that the bottom end of the wire harness passes through the first opening. As the wire harness moves from top to bottom, the bottom end of the wire harness contacts the arc-shaped guide surface and is guided by the arc-shaped guide surface to the second opening. Then, it moves through the second opening to the cable outlet and extends into the frame assembly connecting tube. Next, thread the front brake cable by inserting the bottom end of the front brake cable through the opening at the top of the swivel tube. During the threading process of the front brake cable, the bottom end of the front brake cable is guided by the wire groove on one side of the sleeve and passes through the channel from top to bottom. The overall threading process is convenient, quick, and efficient.

[0017] Preferably, the cross-sectional dimensions of the wire groove gradually decrease from top to bottom.

[0018] During the threading of the front brake cable, the wire groove is arc-shaped and its cross-sectional dimensions gradually decrease from top to bottom. The larger size at the top of the wire groove facilitates the insertion of the front brake cable, making the threading process convenient, quick, and efficient.

[0019] The beneficial effects of this invention are: the arc-shaped guide surface can guide the wire harness, making the wire threading work more convenient and increasing the efficiency of the wire threading work; when the locking screw is tightened to the locking position, the front side of the sleeve abuts against the front side of the inner wall of the rotating shaft tube, so that the sleeve and the rotating shaft tube are locked, which can prevent the sleeve from detaching from the rotating shaft tube; the wire groove is arc-shaped and the cross-sectional size of the wire groove gradually decreases from top to bottom, so that the channel has a guiding function, allowing the front brake cable to pass through the channel quickly, making the front brake cable threading process convenient, fast and efficient.

The first opening 21 is located at the top of the sleeve 1 and communicates with the top of the cavity 2. The second opening 22 is located at the rear side of the sleeve 1 and communicates with the rear side of the cavity 2. An arc-shaped guide surface 23 is provided on the front side of the cavity 2. The top of the arc-shaped guide surface 23 is connected to the front side of the first opening 21, and the bottom of the arc-shaped guide surface 23 is connected to the bottom of the second opening 22. A wire groove 24 for the front brake cable 6 to pass through is vertically provided on one side of the sleeve 1.

[0031] The arc of the arc-shaped guide surface 23 is a quarter circle.

[0032] The first opening 21 has a first rounded corner structure at its outer edge, and the second opening 22 has a second rounded corner structure at its outer edge.

[0033] In this solution, the wiring harness 7 includes a rear brake cable 71 and a data cable 72. The sleeve is inserted into the swivel tube connected to the scooter handlebars. During the threading process, the harness is first threaded through the upper opening of the swivel tube. As the harness moves downwards, its bottom end enters through the first opening. Then, after contacting the curved guide surface, the bottom end is guided to the second opening, and extends outwards through the second opening. Next, the front brake cable is threaded, with its bottom end entering through the upper opening of the swivel tube. During the threading process, the bottom end of the front brake cable is guided by the wire groove on one side of the sleeve, passing through the sleeve from top to bottom. The overall threading process is convenient, quick, and efficient.

[0034] This embodiment provides a scooter handlebar assembly, such as... Figures 2 to 7 As shown, the device includes a scooter handlebar 9, a head tube 3, a pivot tube 4, and a cable sleeve for a scooter as described above. The scooter handlebar 9 is connected to the top of the pivot tube 4. The head tube 3 is sleeved on the outside of the pivot tube 4 and its upper and lower ends are rotatably connected to the pivot tube 4 through a cup bearing 5. The head tube 3 is provided with a cable outlet hole 31 that communicates with the inclined tube 8 connecting to the frame. The pivot tube 4 is provided with an installation hole 41 on the rear side corresponding to the cable outlet hole 31, into which the sleeve 1 extends.

[0036] The wire groove 24 and the inner wall of the shaft tube 4 on the corresponding side form a channel for the front brake cable to pass through.

[0037] The wire groove 24 is arc-shaped.

[0038] In this solution, when installing the sleeve, first insert the sleeve into the shaft tube through the mounting hole, then insert the threaded part of the locking screw into the through hole, so that the threaded part of the locking screw is threadedly connected to the threaded hole on the front side of the sleeve. Then tighten the locking screw, so that the threaded part of the locking screw drives the sleeve forward through the threaded hole until the front side of the sleeve abuts against the front side of the inner wall of the shaft tube. At this time, the locking screw is engaged in the locking position, the nut part of the locking screw is located in the through hole, and the rear side of the sleeve fits against the mounting hole. The sleeve is now installed, and at the same time, the wire groove and the corresponding side of the inner wall of the shaft tube form a channel for the front brake cable to pass through.

[0039] When threading is required, first insert the wire harness into the swivel tube. The bottom end of the wire harness is inserted through the first opening. As the wire harness moves from top to bottom, the bottom end of the wire harness contacts the arc-shaped guide surface and is guided by the arc-shaped guide surface to the second opening. Then, it moves through the second opening to the cable outlet and extends into the frame connecting slant tube. Then, thread the front brake cable into the swivel tube. During the threading process of the front brake cable, the bottom end of the front brake cable passes through the channel and through one side of the sleeve. The threading process is convenient and quick.

[0040] Example 2: A scooter handlebar assembly according to this example. Example 2 has a structure basically the same as Example 1, except that: Figure 8 As shown, the cross-sectional dimensions of the wire groove 24 gradually decrease from top to bottom.

[0041] In this solution, during the threading of the front brake cable, the guide groove is arc-shaped and the cross-sectional size of the guide groove gradually decreases from top to bottom. The larger size at the top of the guide groove facilitates the threading of the front brake cable, making the overall threading process convenient, fast, and efficient.
