[0036] like Figures 1 to 3 As shown, this utility model provides a telescopic structure for an electric scooter, including an adjusting T-tube 100, a round tube 200, and a locking mechanism 300; the round tube 200 has an opening at its top end and a cavity inside, the bottom end of the adjusting T-tube 100 extends into the cavity along the opening, and the adjusting T-tube 100 can slide along the extension direction of the cavity; the top end of the adjusting T-tube 100 is used to install a handle, and the top end of the round tube 200 is connected to the front fork of the electric scooter; the locking mechanism 300 is located at the end where the round tube 200 and the adjusting T-tube 100 meet, and is used to limit the length of the adjusting T-tube 100 extending into the cavity.

[0037] In this embodiment, the telescopic mechanism includes an adjusting T-tube 100, a round tube 200, and a locking mechanism 300. The bottom end of the adjusting T-tube 100 extends into the cavity formed inside the round tube 200 through the opening at the top end of the round tube 200, and the adjusting T-tube 100 can slide along the extension direction of the cavity, thereby changing the relative length between the adjusting T-tube 100 and the round tube 200. A locking mechanism 300 is installed at the end where the round tube 200 and the adjusting T-tube 100 meet, which is used to limit the length of the adjusting T-tube 100 extending into the cavity, so that the adjusting T-tube 100 and the round tube 200 can be locked after adjustment, thereby improving the safety of use. The top end of the adjusting T-tube 100 is used to install a handlebar, and the top end of the round tube 200 is connected to the front fork of the electric scooter. Thus, the relative height between the handlebar and the vehicle body can be changed through the adjusting T-tube 100, thereby making it suitable for users of different heights to use alternately.

[0038] According to one embodiment provided by this utility model, such as Figure 2 and Figure 3 As shown, the locking mechanism 300 includes a housing 301, an adjusting component, and a locking block 302. The housing 301 covers the outer wall of the circular tube 200. The adjusting component and the locking block 302 are located inside the housing 301 and are locked to the side wall of the adjusting T-tube 100. The adjusting component is connected to the locking block 302 in a driving manner. The adjusting component can drive the locking block 302 to move closer to or away from the adjusting T-tube 100.

[0039] In this embodiment, the housing 301 covers the outer wall of the circular tube 200, ensuring the aesthetics of the telescopic structure during use. Simultaneously, an adjustment component and a locking block 302 can be installed inside the housing 301. The locking block 302 directly engages with the side wall of the adjustment T-tube 100. The adjustment component moves the locking block 302 closer to or further away from the adjustment T-tube 100. When the locking block 302 moves away from the adjustment T-tube 100, the length of the end of the adjustment T-tube 100 extending into the cavity of the circular tube 200 can be changed. When the locking block 302 engages with the side wall of the adjustment T-tube 100, the fixation between the adjustment T-tube 100 and the circular tube 200 is completed.

[0040] According to one embodiment provided by this utility model, such as Figure 2 and Figure 3 As shown, the side wall of the adjusting T tube 100 is provided with several grooves 101, which are spaced apart along the extension direction of the adjusting T tube 100. The outer wall of the snap-fit ​​block 302 is provided with several protrusions 303, which can snap into the grooves 101.

[0041] In this embodiment, preferably, the locking between the adjusting T-tube 100 and the round tube 200 is achieved by the locking engagement of the groove 101 on the side wall of the adjusting T-tube 100 and the protrusion 303 on the outer wall of the locking block 302, so as to prevent the adjusting T-tube 100 from sliding in the cavity of the round tube 200 and affecting its use.

[0042] According to one embodiment provided by this utility model, such as Figure 3 As shown, the adjustment assembly includes an unlocking wrench 304, an adjusting rod 305, and an elastic reset member 306. The unlocking wrench 304 is installed on the housing 301 and can rotate along the axial direction of the housing 301. One end of the unlocking wrench 304 abuts against the adjusting rod 305. The side of the adjusting rod 305 facing away from the unlocking wrench 304 has an arc portion 307, which fits against the outer wall of the round tube 200. One end of the adjusting rod 305 is connected to the locking block 302, and the other end abuts against the elastic reset member 306. The end of the elastic reset member 306 facing away from the adjusting rod 305 abuts against the outer wall of the round tube 200.

[0043] In this embodiment, the adjustment assembly includes an unlocking wrench 304, an adjusting rod 305, and an elastic reset member 306. The unlocking wrench 304 is rotatable along the axial direction of the housing 301. Since one end of the unlocking wrench 304 abuts against the adjusting rod 305, and the side of the unlocking wrench 304 that abuts against the adjusting rod 305 is arc-shaped, when the unlocking wrench 304 rotates to a certain position, it compresses the elastic reset member 306 disposed between the adjusting rod 305 and the outer wall of the circular tube 200. Then, the adjusting rod 305 drives the locking block 302 away from the groove 101. The elastic reset member 306 allows the locking block 302 to reset after the unlocking wrench 304 resets, continuing to engage with the groove 101. With the above configuration, the length of the adjusting T-tube 100 extending into the cavity of the circular tube 200 can only be changed when the unlocking wrench 304 rotates to a certain position, thereby preventing danger caused by accidental contact with the unlocking wrench 304 during use of the telescopic mechanism.

[0044] Preferably, the elastic reset element 306 is a spring.

[0045] According to one embodiment provided by this utility model, such as Figure 1 and 3 As shown, the housing 301 has a mounting position, and side plates 308 are provided on both sides of the mounting position. The side plates 308 have a first pin hole, and the unlocking wrench 304 has a second pin hole 309. The unlocking wrench 304 is located in the mounting position, and the locking pin passes through the first pin hole and the second pin hole 309 in sequence.

[0046] In this embodiment, the housing 301 is provided with a mounting position, and side plates 308 are provided on both sides of the mounting position. The unlocking wrench 304 is rotatably mounted in the mounting position between the two side plates 308 by means of a locking pin, so as to facilitate its use for opening.

[0047] According to one embodiment provided by this utility model, such as Figure 3 As shown, the adjusting rod 305 includes a straight section 310, an inclined section 311, and a connecting section 312; the straight section 310, the inclined section 311, and the connecting section 312 are connected end to end in sequence; the side wall of the straight section 310 abuts against the elastic reset member 306, the side of the inclined section 311 facing away from the round tube 200 is in contact with the side wall of the unlocking wrench 304, and the other side is provided with an arc portion 307, and the end of the connecting section 312 facing away from the inclined section 311 is connected to the locking block 302.

[0048] In this embodiment, the adjusting rod 305 includes a straight section 310, an inclined section 311, and a connecting section 312, which are connected end to end in sequence. The straight section 310 abuts against the elastic reset member 306. The arc portion 307 is located on the side of the inclined section 311 facing the outer wall of the circular tube 200. The side of the inclined section 311 facing away from the circular tube 200 is in contact with the side wall of the unlocking wrench 304. When the unlocking wrench 304 is rotated, the straight section will be subjected to force, thereby compressing the elastic reset member 306. The connecting section 312 drives the locking block 302 to move.

[0049] According to one embodiment provided by this utility model, such as Figure 3 As shown, the end of the connecting section 312 is provided with an oblong hole, the snap-fit ​​block 302 is provided with a connecting plate 313, the connecting plate 313 is provided with a third pin hole 314, and the sliding pin passes through the third pin hole 314 and the oblong hole in sequence.

[0050] In this embodiment, the end of the connecting segment 312 is provided with an oblong hole, and the connecting plate 313 is provided on the snap-fit ​​block 302. The connecting segment 312 and the connecting plate 313 are connected by a sliding pin so that the connecting segment 312 can drive the snap-fit ​​block 302 to move.

[0051] Furthermore, the sliding pin can slide along the extension direction of the oblong hole.

[0052] In this embodiment, the end of the connecting section 312 is provided with an oblong hole, and the sliding pin can slide along the extension direction of the oblong hole. Thus, by the rotation of the arc portion 307 of the adjusting rod 305 on the outer wall of the circular tube 200 and the sliding pin sliding in the oblong hole, in conjunction with the elastic reset member 306 abutting at the end of the adjusting rod 305, the locking block 302 can be driven to move away from or towards the groove 101, so as to change the relative height between the adjusting T tube 100 and the circular tube 200.

[0053] According to one embodiment provided by this utility model, such as Figure 3 As shown, the locking mechanism 300 also includes an upper cover 315, which is located at the top of the housing 301.

[0054] In this embodiment, the position of the locking mechanism 300 can be effectively restricted by the upper cover 315, and the upper cover 315 is provided with rounded corners to prevent the user's hands from being scratched during use.

[0055] This utility model also provides an electric scooter, including the telescopic structure described above.

[0056] In this embodiment, the electric scooter includes the aforementioned telescopic structure. By using this telescopic mechanism, the relative height between the handlebars and the scooter body can be easily adjusted, making it suitable for users of different heights to use alternately, effectively improving the flexibility of the electric scooter. Simultaneously, the safety of the rider is ensured by the use of the unlocking wrench 304.

[0057] Preferably, a handle can be installed at the top of the adjusting T-tube 100, and the end of the round tube 200 away from the adjusting T-tube 100 can be connected to the front fork of the electric scooter, thereby completing the installation of the telescopic structure on the body of the electric scooter.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
