[0031] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0032] like Figure 1-8As shown, this embodiment provides a foldable electric scooter, which includes a front end assembly 100, a connecting tube 200, and a handlebar tube 300. The connecting tube 200 is fixedly mounted on the front end assembly 100, and the handlebar tube 300 is mounted on the end of the connecting tube 200, thereby enabling the handlebar tube 300 to be installed and used on the front end assembly 100. The handlebar tube 300 provides a handhold for the rider. Furthermore, the front end assembly 100 is fixedly mounted on the front riser tube 400 of the vehicle. The lowermost end of the riser tube 400 is connected to the top end of the front fork 500 on which the front wheel 510 is mounted. The front fork 500 is rotatably mounted on a passenger-carrying frame assembly 600. After the rider holds the handlebar tube 300, the handlebar tube 300, riser tube 400, front fork 500, and front wheel 510 can be rotated relative to the frame assembly 600 by operating the handlebar tube 300. Furthermore, a rear wheel 610 is installed on the end of the frame assembly 600 away from the front wheel 510, and a rear fender assembly 620 is also installed and fixed on the frame assembly 600 above the rear wheel 610.

[0033] Furthermore, the first end of the horizontal tube 300 near the connecting tube 200 is rotatably connected to the corresponding end of the connecting tube 200, so that the angle between the horizontal tube 300 and the connecting tube 200 can be adjusted. When the electric scooter of this embodiment needs to be stored, the horizontal tube 300 can be rotated so that the horizontal tube 300 changes from a state coaxial with the connecting tube 200 to a state at a certain angle with the connecting tube 200, thereby reducing the width of the electric scooter to a certain extent, which facilitates the storage and transportation of the electric scooter.

[0034] Furthermore, a sliding sleeve 310 is also fitted on the first end of the horizontal tube 300. The sliding sleeve 310 can reciprocate along the axial direction of the horizontal tube 300. When the horizontal tube 300 is rotated to be coaxial with the connecting tube 200, the sliding sleeve 310 can be moved to the rotational connection point between the horizontal tube 300 and the connecting tube 200, so that the sliding sleeve 310 fits on the rotational connection point between the horizontal tube 300 and the connecting tube 200. In this way, the sliding sleeve 310 can limit the rotation of the horizontal tube 300, so that the horizontal tube 300 can remain coaxial with the connecting tube 200. When it is necessary to store the electric scooter, the sliding sleeve 310 can be moved so that the rotating connection between the handlebar 300 and the connecting tube 200 is no longer covered by the sliding sleeve 310. This allows the handlebar 300 to rotate relative to the connecting tube 200, thereby adjusting the angle between the handlebar 300 and the connecting tube 200. This reduces the width of the electric scooter and makes it easier to store.

[0035] It should be noted that when the horizontal tube 300 and the connecting tube 200 are in a coaxial state, the operating sleeve 310 moves toward the connecting tube 200. When the sleeve 310 is fitted at the rotatable connection between the horizontal tube 300 and the connecting tube 200, the two ends of the sleeve 310 will also fit the first end of the corresponding horizontal tube and the end of the connecting tube 200, thereby improving the stability and safety of the sleeve 310 in limiting the rotation of the horizontal tube 300.

[0036] In some embodiments, a first connecting block 301 is provided on the first end of the horizontal tube 300, and a second connecting block 210 is provided on the corresponding end of the connecting tube 200. The horizontal tube 300 and the connecting tube 200 are rotatably connected through the first connecting block 301 and the second connecting block 210. Specifically, the first connecting block 301 and the second connecting block 210 are connected through a shaft hole to realize relative rotation between the first connecting block 301 and the second connecting block 210, thereby realizing relative rotation between the horizontal tube 300 and the connecting tube 200.

[0037] In some embodiments, a first return spring 320 is provided between the sliding sleeve 310 and the handle tube 300, and the sliding sleeve 310 can be automatically returned to its original position by the provision of the first return spring 320.

[0038] It should be noted that in the non-folded state, the horizontal tube 300 and the connecting tube 200 are coaxial. At this time, the sliding sleeve 310 is fitted onto the rotatable connection between the horizontal tube 300 and the connecting tube 200. When the electric scooter needs to be folded up, the rider can operate the sliding sleeve 310, causing it to move by compressing the first return spring 320. This moves the sliding sleeve 310 away from the rotatable connection between the horizontal tube 300 and the connecting tube 200, allowing the horizontal tube 300 to rotate relative to the connecting tube 200. The handlebars can be rotated to allow for storage. When the electric scooter is needed, the handlebar tube 300 can be rotated so that it is coaxial with the connecting tube 200. At this time, the first return spring 320, which is in a compressed state, can push the sliding sleeve 310 to move toward the connecting tube 200. This allows the sliding sleeve 310 to move to the rotational connection between the handlebar tube 300 and the connecting tube 200 under the push of the first return spring 320, thereby limiting the rotation of the handlebar tube 300 by the sliding sleeve 310.

[0039] By setting the first return spring 320, the problem of the driver forgetting to move the sliding sleeve 310 can be better avoided, which can improve safety and facilitate the driver's use.

[0040] In some embodiments, an annular groove 302 is formed on the circumferential sidewall of the first end of the horizontal tube 300; an annular retaining ring 311 is provided on the inner sidewall of the sliding sleeve 310, and the retaining ring 311 is located at the middle position in the axial direction of the sliding sleeve 310; wherein, a first return spring 320 is sleeved in the annular groove 302, and the sliding sleeve 310 is sleeved outside the first return spring 320; furthermore, one end of the first return spring 320 abuts against the sidewall of the annular groove 302 away from the connecting tube 200, and the other end of the first return spring 320 abuts against the sidewall of the retaining ring 311 near the sidewall of the horizontal tube 300. Preferably, one end of the first return spring 320 is fixedly connected to the annular groove 302, and the other end of the first return spring 320 is fixedly connected to the retaining ring 311.

[0041] Understandably, when the electric scooter needs to be stored, the driver operates the sliding sleeve 310 to move it away from the connecting tube 200. During this process, the sliding sleeve 310 compresses the first return spring 320 through the retaining ring 311. As the first return spring 320 is compressed, the retaining ring 311 also moves into the annular groove 302 until the sliding sleeve 310 completely exits the rotatable connection between the handlebar 300 and the connecting tube 200, allowing the handlebar 300 to rotate relative to the connecting tube 200. When the electric scooter needs to be used, the handlebar 300 is rotated so that it is coaxial with the connecting tube 200. During this process, the first return spring 320 pushes the retaining ring 311 out of the annular groove 302 and continues to move towards the connecting tube 200 until the sliding sleeve 310 is repositioned at the rotatable connection between the handlebar 300 and the connecting tube 200.

[0042] It should be noted that the part of the sliding sleeve 310 on the side of the retaining ring 311 away from the handlebar tube 300 is used to fit the rotating connection between the handlebar tube 300 and the connecting tube 200. Furthermore, when the axial dimension of the sliding sleeve 310 is large, the part of the sliding sleeve 310 on the side of the retaining ring 311 away from the handlebar tube 300 can also fit the corresponding end of the connecting tube 200.

[0043] In some embodiments, the seat tube 400 and the fork 500 are rotatably connected. When the electric scooter needs to be stored, the seat tube 400 can be rotated relative to the fork 500, causing the seat tube 400 to rotate toward the frame assembly 600, that is, causing the front bumper assembly 100 to move toward the rear fender assembly 620, thereby enabling the seat tube 400 to be folded. When the electric scooter needs to be used, the seat tube 400 can be rotated relative to the fork 500, causing the seat tube 400 to return to its original position.

[0044] Understandably, when storing the electric scooter, the handlebar 300 can be rotated relative to the connecting tube 200 to form a 90-degree angle between them, thus reducing the width of the electric scooter. Then, the upright 400 can be rotated relative to the front fork 500 to bring the front bumper assembly 100 closer to the rear fender assembly 620, thus reducing the height of the electric scooter.

[0045] In some embodiments, a third connecting block 410 is provided at the end of the riser 400 near the fork 500, and a fourth connecting block 520 is provided at the end of the fork 500 near the riser 400. The third connecting block 410 and the fourth connecting block 520 are hinged together, thereby enabling better rotation between the riser 400 and the fork 500.

[0046] In some embodiments, a buckle 521 is provided between the third connecting block 410 and the fourth connecting block 520. When the riser 400 is rotated through the third connecting block 410 and the fourth connecting block 520 to the electric scooter in use, the buckle 521 can fix the relative position between the third connecting block 410 and the fourth connecting block 520 to restrict the relative rotation between the third connecting block 410 and the fourth connecting block 520, thereby fixing the relative position between the riser 400 and the front fork 500, so that the electric scooter can meet the needs of the driver.

[0047] Furthermore, the hinge between the third connecting block 410 and the fourth connecting block 520 is located on the side near the rear fender assembly 620, that is, the rear side in the forward direction of the electric scooter, while the buckle 521 is located on the other side opposite to the hinge between the third connecting block 410 and the fourth connecting block 520, that is, the front side in the forward direction of the electric scooter.

[0048] In some embodiments, a slot 110 is provided on the front bumper assembly 100, and a hook 621 is provided on the upper surface of the rear fender assembly 620. When the electric scooter needs to be stored, the stem 400 is rotated relative to the fork 500, causing the front bumper assembly 100 to move toward the rear fender assembly 620. During this process, the slot 110 also moves toward the hook 621. When the front bumper assembly 100 is in place, the hook 621 can extend into the slot 110, thereby limiting the front bumper assembly 100 to a certain extent, improving the positional stability of the front bumper assembly 100 and the stem 400, and preventing the front bumper assembly 100 and the stem 400 from shaking to a large extent.

[0049] It is understandable that either the slot 110 or the hook 621 can be configured to have a certain degree of elasticity. For example, the hook 621 can be configured to have a certain degree of elasticity. When the front assembly 100 moves toward the rear fender assembly 620, the slot 110 can squeeze the hook 621, so that the hook 621 can extend into the slot 110 through elastic deformation, thereby achieving the function of limiting the front assembly 100.

[0050] In some embodiments, the hook 621 is disposed on the rear fender assembly 620 by a second return spring (not shown in the figure). Specifically, the hook 621 is capable of reciprocating in the forward direction of the electric scooter by means of the second return spring.

[0051] It should be noted that when the front bumper assembly 100 moves toward the rear fender assembly 620, the hook 621 can be operated to move away from the riser tube 400 by compressing the second return spring. After the front bumper assembly 100 is in place, the slot 110 on the front bumper assembly 100 is on the side of the hook 621 closer to the front wheel 510. At this time, the hook 621 can be released, so that the hook 621 moves toward the slot 110 under the push of the second return spring until the hook 621 extends into the slot 110. Then, with the cooperation of the hook 621 and the slot 110, the front bumper assembly 100 is limited. When the electric scooter needs to be used, the hook 621 can be operated to compress the second return spring and move.

[0052] In some embodiments, a button 622 is provided on the rear fender assembly 620. Pressing the button 622 can drive the hook 621 to compress the second return spring, thereby achieving automated control and preventing the driver from directly touching the hook 621, thus improving operational safety.

[0053] Furthermore, the button 622 can drive the hook 621 to compress the second return spring by providing a connecting rod (not shown in the figure) in the rear fender assembly 620. The button 622 can also be controlled by providing a drive motor (not shown in the figure) in the rear fender assembly 620, with the button 622 electrically connected to the drive motor to drive the hook 621 to compress the second return spring. There are no particular limitations on this.

[0054] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
