Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a folding mechanism and an electric scooter. Background Technology

[0002] Electric scooters are transportation and recreational tools based on traditional human-powered scooters, supplemented by electric motors. Their lightweight, convenient, and portable nature has made them popular with consumers. Most electric scooters on the market have a folding mechanism between the vertical tube and the front fork, allowing the vertical tube to be folded up above the footboard for storage. However, some current folding mechanisms concentrate stress in one spot when locked, making them prone to malfunction after prolonged use and exhibiting poor reliability. Utility Model Content

[0003] The main objective of this invention is to propose a folding mechanism that aims to improve the reliability of the folding mechanism.

[0004] To achieve the above objectives, the folding mechanism proposed in this utility model includes:

[0005] A folding seat includes a fixed seat and a rotating seat, wherein one side of the fixed seat and the rotating seat are hinged to each other, and the rotating seat is provided with a first locking part;

[0006] A locking mechanism is rotatably mounted on the other side of the fixed base and has a first rotation axis. The locking mechanism has an abutment portion and a second locking portion on the side facing the rotating base; and

[0007] A limiting member is rotatably mounted on the other side of the rotating seat, and the limiting member has at least a second rotation axis parallel to the first rotation axis.

[0008] The scooter folding mechanism has a used state in which the fixed seat and the rotating seat are stacked together, and a folded state in which the fixed seat and the rotating seat are unfolded. In the used state, the second locking part is engaged with the first locking part, and the limiting member abuts against the side of the abutting part facing the fixed seat.

[0009] Optionally, the limiting member includes a rotating shaft and a limiting post disposed on the rotating shaft. The rotating shaft is rotatably mounted on the rotating seat, and the end of the limiting post away from the rotating shaft abuts against the abutting part.

[0010] Optionally, the rotating shaft is provided with an adjusting screw hole, and the limiting post is screwed into the adjusting screw hole;

[0011] Optionally, the end of the limiting post away from the rotating shaft is provided with an abutment surface, which is a convex spherical surface.

[0012] Optionally, the rotating seat has a mounting side and a rotating portion disposed on the mounting side, the rotating shaft is mounted on the rotating portion, and the limiting member has a first state in which the limiting post is parallel to the mounting side and a second state in which the limiting post is inclined relative to the mounting side; the folding mechanism further includes a spring, the spring being connected between the rotating shaft and the rotating seat, and having elastic deformation that drives the limiting member to move from the first state to the second state.

[0013] Optionally, the abutting portion is provided with a receiving groove, and in the use state, the free end of the limiting member abuts in the receiving groove.

[0014] Optionally, the axis of rotation between the fixed seat and the rotating seat is parallel to the first axis of rotation.

[0015] Optionally, the rotation axis between the fixed seat and the rotating seat is a third rotation axis, and the first locking part is located on the rotating seat on the side away from the third rotation axis; the first locking part is spaced apart on the side of the limiting member away from the fixed seat, and the second locking part is spaced apart on the side of the abutment part away from the fixed seat.

[0016] Optionally, the locking mechanism includes a mounting member, an unlocking member, and an elastic member. The mounting member is rotatably mounted on the fixed base, and the unlocking member is movably mounted on the mounting member, having a snap-fit ​​position and an unlocked position. The elastic member is disposed between the mounting member and the unlocking member, and has elastic deformation that drives the unlocking member to move from the unlocked position to the snap-fit ​​position. The unlocking member has a second snap-fit ​​portion, and the mounting member has the abutment portion. In the usage state, the unlocking member is in the snap-fit ​​position, and the second snap-fit ​​portion snaps into the first snap-fit ​​portion.

[0017] Optionally, the unlocking component is slidably mounted on the mounting component and disposed near the free end of the mounting component. The sliding direction of the unlocking component is perpendicular to the rotation axis of the mounting component, and the unlocking position is farther from the rotation axis of the mounting component than the snap-fit ​​position.

[0018] This utility model also proposes an electric scooter, including a pedal assembly, a front fork, a handlebar assembly, and a folding mechanism as described above. The front fork is rotatably mounted on the front end of the pedal assembly, the fixed seat of the folding mechanism is mounted on the upper end of the front fork, and the rotating seat of the folding mechanism is mounted on the lower end of the handlebar assembly.

[0019] This utility model's technical solution hinges one side of a fixed base and a rotating base together, and provides a rotatable locking mechanism and a limiting member on the other side of the fixed base and the rotating base, respectively. The rotating base has a first engaging portion, and the locking mechanism has an abutment portion and a second engaging portion on the side facing the rotating base. In use, the second engaging portion engages with the first engaging portion, and the limiting member abuts against the side of the abutment portion facing the fixed base. This engagement of the first and second engaging portions restricts the locking mechanism from rotating away from the rotating base. Furthermore, the limiting member and the abutment portion press the rotating base firmly against the fixed base. Compared to a method that relies on the first and second engaging portions to restrict the locking mechanism's rotation relative to the rotating base while simultaneously pressing the rotating base against the fixed base, this method disperses the force between the locking mechanism and the rotating base, avoiding force concentration at the first and second engaging portions. It simplifies the structure of the first and second engaging portions while ensuring their reliability, thereby improving the reliability of the folding mechanism. Attached Figure Description

[0037] This utility model proposes a folding mechanism for electric scooters.

[0038] In the embodiments of this utility model, such as Figures 1 to 10 As shown, the folding mechanism includes a folding seat 10, a locking mechanism 20, and a limiting member 25. The folding seat 10 includes a fixed seat 11 and a rotating seat 12. One side of the fixed seat 11 and the rotating seat 12 are hinged to each other. The rotating seat 12 is provided with a first latching part 121.

[0039] The locking mechanism 20 is rotatably mounted on the other side of the fixed seat 11 (i.e., one side of the fixed seat 11 is hinged to the rotating seat 12, and the other side is hinged to the locking mechanism 20), and has a first rotation axis. The locking mechanism 20 has an abutment part 213 and a second snap-fit ​​part 2231 on the side facing the rotating seat 12. The limiting member 25 is rotatably mounted on the other side of the rotating seat 12 (i.e., one side of the rotating seat 12 is hinged to the fixed seat 11, and the other side is provided with the limiting member 25). The limiting member 25 has at least a second rotation axis parallel to the first rotation axis.

[0040] The scooter folding mechanism has a working state in which the fixed seat 11 and the rotating seat 12 are stacked together, and a folded state in which the fixed seat 11 and the rotating seat 12 are unfolded. In the working state, the second locking part 2231 is engaged with the first locking part 121, and the limiting member 25 abuts against the side of the abutting part 213 facing the fixed seat 11.

[0041] It can be understood that both the first and second rotation axes are virtual axes, and the inner side of the locking mechanism 20 is the side facing the rotating seat 12 when in use.

[0042] The first engaging portion 121 is spaced apart from the abutting portion 213, and the second engaging portion 2231 is spaced apart from the limiting member 25. In use, the first engaging portion 121 and the second engaging portion 2231 engage to restrict the locking mechanism 20 from rotating away from the rotating seat 12. The abutting portion 213 is located above the limiting member 25, that is, the abutting portion 213 can press against the limiting member 25, thereby pressing the rotating seat 12 tightly onto the fixed seat 11 and avoiding a gap between the rotating seat 12 and the fixed seat 11 in use. Compared to the method of restricting the locking mechanism 20 from rotating relative to the rotating seat 12 by the first latching part 121 and the second latching part 2231 while pressing the rotating seat 12 against the fixed seat 11, the locking mechanism 20 is restricted from rotating away from the rotating seat 12 by the latching engagement of the first latching part 121 and the second latching part 2231. In addition, the rotating seat 12 is pressed against the fixed seat 11 by the limiting member 25 and the abutment part 213. This can distribute the force between the locking mechanism 20 and the rotating seat 12, and avoid the force being concentrated at the first latching part 121 and the second latching part 2231. This simplifies the structure of the first latching part 121 and the second latching part 2231 while ensuring the reliability of the first latching part 121 and the second latching part 2231, thereby improving the reliability of the folding mechanism.

[0043] The axis of rotation between the fixed base 11 and the rotating base 12 is defined as the third axis of rotation. In some embodiments, the first engaging portion 121 is located on the rotating base 12 on the side away from the third axis of rotation. This arrangement, with the first engaging portion 121 located away from the third axis of rotation, improves the limiting effect on the rotating base 12 during use and simplifies the structure of the first engaging portion 121. Of course, in other embodiments, the first engaging portion 121 can also be provided on both opposite sides of the rotating base 12 along the direction of extension of the third axis of rotation, and the locking mechanism 20 provides a second engaging portion 2231 for each first engaging portion 121.

[0044] In some embodiments, the rotation axis (third rotation axis) between the fixed base 11 and the rotating base 12 is parallel to the first rotation axis. Specifically, in the use state, the first latching portion 121 abuts against the side of the second latching portion 2231 opposite to the rotating base 12, and the second latching portion 2231 abuts against the side of the first latching portion 121 facing the rotating base 12. When the folding mechanism is used in an electric scooter, the locking mechanism 20 is rotatably mounted on the front side of the fixed base 11, and the rotation axis between the fixed base 11 and the rotating base 12, as well as the first rotation axis, extends in the left-right direction. The locking mechanism 20 can rotate forward and move away from the rotating base 12. In this way, in the use state, the side of the rotating base 12 away from its rotation axis can be locked better. While ensuring the locking effect of the locking mechanism 20 on the rotating base 12 and the fixed base 11, the size of the folding mechanism in the front-back direction of the electric scooter can be reduced.

[0045] Of course, in other embodiments, the rotation axis between the fixed seat 11 and the rotating seat 12 can be perpendicular to the first rotation axis. The first locking part 121 is provided with a groove, and the second locking part 2231 is provided with a glass ball screw. When the locking mechanism 20 rotates to the point where the second locking part 2231 corresponds to the first locking part 121, the steel ball of the glass ball screw is engaged in the groove.

[0046] In some embodiments, the limiting member 25 includes a rotating shaft 251 and a limiting post 252 disposed on the rotating shaft 251. The rotating shaft 251 is rotatably mounted on the rotating seat 12, and the end of the limiting post 252 away from the rotating shaft 251 abuts against the abutment portion 213. That is, the rotating shaft 251 is coaxial with the second rotation axis, which simplifies the structure of the limiting member 25 and also simplifies the structure on the rotating seat 12 for mounting the rotating shaft 251, making assembly easier. Of course, in other embodiments, a spherical portion can be provided at one end of the limiting member 25, and a semi-circular groove can be provided on the rotating seat 12. The spherical portion is rotatably mounted in the semi-circular groove, and the other end of the limiting member 25 abuts against the abutment portion 213.

[0047] Optionally, the rotating shaft 251 is provided with an adjusting screw hole 2511, and the limiting post 252 is screwed into the adjusting screw hole 2511. This allows adjustment of the distance between the end of the limiting post 252 away from the adjusting screw hole 2511 and the rotating shaft 251. In use, the limiting post 252 can be adjusted to ensure that the rotating seat 12 is pressed tightly against the fixed seat 11, which reduces the precision requirements of the fitting between the limiting member 25 and the locking mechanism 20, and helps to reduce production costs. In other embodiments, the rotating shaft 251 and the limiting post 252 can be integrally formed or welded together.

[0048] In some embodiments, the end of the limiting post 252 away from the rotating shaft 251 is provided with an abutment surface 253, which is convex spherical. Thus, when the latch is rotated so that the abutment portion 213 gradually approaches the limiting post 252, the abutment surface 253 gradually contacts the abutment portion 213, and the pressure between them gradually increases until they are properly engaged. This provides good guidance during installation, ensuring accurate engagement between the abutment portion 213 and the limiting post 252.

[0049] In some embodiments, the rotating base 12 has a mounting side 125 and a rotating portion 126 disposed on the mounting side 125. A rotating shaft 251 is mounted on the rotating portion 126. The limiting member 25 has a first state in which the limiting post 252 is parallel to the mounting side 125 and a second state in which the limiting post 252 is inclined relative to the mounting side 125. The folding mechanism also includes a spring 26, which is connected between the rotating shaft 251 and the rotating base 12, and has elastic deformation to drive the limiting member 25 to move from the first state to the second state. Specifically, the fixed base 11 has a first end face, the rotating base 12 has a second end face, the mounting side 125 is adjacent to the second end face, and in the use state, the second end face and the first end face are stacked together.

[0050] When the folded state is in which the limiting member 25 is not subjected to external force, the limiting member 25 can be in the second state under the action of the spring 26. When the rotating seat 12 is rotated to be stacked on top of the fixed seat 11, and the locking mechanism 20 is rotated to gradually approach the rotating seat 12, the abutment part 213 can gradually contact the limiting post 252, and as the locking mechanism 20 rotates, it gradually drives the limiting post 252 to rotate to the first state. At this time, the first locking part 121 and the second locking part 2231 are engaged, and the folding mechanism is in the use state. This ensures that every time the folding mechanism is switched from the folded state to the use state, the abutment part 213 can gradually contact the limiting post 252 until it is in place, ensuring the installation effect.

[0051] Optionally, the spring 26 is a torsion spring and is fitted onto the rotating shaft 251, which simplifies the installation structure of the spring 26.

[0052] In some embodiments, the abutment portion 213 is provided with a receiving groove, and in the use state, the free end of the limiting member 25 abuts against the receiving groove. Thus, during the process of switching the folding mechanism from the folded state to the use state, the limiting member 25 can be positioned and limited, preventing the limiting member 25 from shaking after the locking mechanism 20 contacts the abutment portion 213 and before the first engaging portion 121 and the second engaging portion 2231 engage, ensuring the stability of the limiting member 25 during the switching process. Furthermore, in the use state, the limiting member 25 can be limited, ensuring the installation stability of the limiting member 25.

[0053] In some embodiments, the first engaging portion 121 is spaced apart from the side of the limiting member 25 away from the fixed base 11, and the second engaging portion 2231 is spaced apart from the side of the abutting portion 213 away from the fixed base 11. That is, the abutting portion 213 is located between the second engaging portion 2231 and the fixed base 11, and in the use state, the limiting member 25 is located between the first engaging portion 121 and the fixed base 11. It can be understood that in the use state, the cooperation structure between the abutting portion 213 and the limiting member 25 is the main force-bearing position for holding the rotating base 12 in the use state. By bringing the abutting portion 213 and the limiting member 25 close to the first rotation axis, the stability of the abutting portion 213 and the limiting member 25 can be ensured.

[0054] In some embodiments, the locking mechanism 20 includes a mounting member 21, an unlocking member 22, and an elastic member 23. The mounting member 21 is rotatably mounted on the fixed base 11, and the unlocking member 22 is movably mounted on the mounting member 21 and has a snap-fit ​​position and an unlocked position. The elastic member 23 is disposed between the mounting member 21 and the unlocking member 22 and has elastic deformation that drives the unlocking member 22 to move from the unlocked position to the snap-fit ​​position. The unlocking member 22 has a second snap-fit ​​portion 2231, and the mounting member 21 has an abutment portion 213. In the use state, the unlocking member 22 is in the snap-fit ​​position, and the second snap-fit ​​portion 2231 snaps into the first snap-fit ​​portion 121.

[0055] Specifically, the unlocking component 22 is slidably mounted on the mounting component 21 and positioned close to the free end of the mounting component 21. The sliding direction of the unlocking component 22 is perpendicular to the rotation axis 251 of the mounting component 21, and the unlocking position is farther from the rotation axis 251 of the mounting component 21 compared to the engaging position. That is, the length direction of the mounting component 21 is perpendicular to the first rotation axis 251, and the unlocking component 22 is slidably mounted on the mounting component 21 along the length direction of the mounting component 21. This reduces the width of the locking mechanism 20, which, when used in electric scooters, reduces the size of the locking mechanism 20 in the left-right direction of the electric scooter.

[0056] In the use state, the second latching part 2231 abuts against the side of the first latching part 121 facing the first rotation axis, and the first latching part 121 abuts against the side of the second latching part 2231 facing the mounting member 21. The elastic member 23 keeps the unlocking member 22 engaged with the first latching part 121. When switching from the use state to the folded state, the unlocking member 22 can be pulled from the side of the mounting member 21 away from the rotating base 12, so that the unlocking member 22 moves to a position where the second latching part 2231 is away from the first latching part 121. This allows the mounting member 21 to be rotated away from the rotating base 12, thereby rotating the rotating base 12 and switching the folding mechanism to the folded state.

[0057] Conversely, when switching from the folded state to the use state, first rotate the rotating base 12 so that it is stacked on top of the fixed base 11, then rotate the mounting part 21 so that it is close to the rotating base 12. Then pull the unlocking part 22 from the side of the mounting part 21 away from the rotating base 12 so that the unlocking part 22 moves to the position where the second locking part 2231 is misaligned with the first locking part 121. After the mounting part 21 is rotated into place, release the unlocking part 22. Under the action of the elastic member 23, the unlocking part 22 can move to the position where the second locking part 2231 is engaged with the first locking part 121, thereby completing the switch to the use state.

[0058] In this way, when used in electric scooters, it can ensure structural reliability and prevent the locking mechanism 20 from being easily opened. It can also make the locking mechanism 20 and the unlocking part 22 located at the front, so that the unlocking part 22 can be easily observed when the user needs to switch states. The unlocking part 22 can be operated accurately, reducing the time spent on trial and error and making it convenient for the user.

[0059] Of course, in other embodiments, the sliding direction of the unlocking member 22 may be parallel to the first rotation axis; or, the unlocking member 22 may be rotatably mounted on the mounting member 21, and the rotation axis of the unlocking member 22 may be perpendicular to the first rotation axis and the length direction of the mounting member 21.

[0060] In some embodiments, the end of the unlocking member 22 furthest from the first rotation axis is not higher than the free end of the mounting member 21. Specifically, even when the unlocking member 22 moves to its furthest position from the first rotation axis, the end of the unlocking member 22 furthest from the first rotation axis is flush with or spaced apart from the free end of the mounting member 21. This allows the user to support their hand on the free end of the mounting member 21 when pulling the unlocking member 22, facilitating the application of force and operation. It also avoids the risk of the unlocking member 22 being damaged by collisions when its furthest end is higher than the free end of the mounting member 21, thus improving its reliability. Of course, in other embodiments, when the unlocking member 22 moves to its furthest position from the first rotation axis, it may also extend beyond the free end of the mounting member 21.

[0061] In some embodiments, the mounting member 21 is provided with a first through hole 211, and the unlocking member 22 includes a handle 221 and a locking block 223. The handle 221 is plate-shaped and located on the side of the mounting member 21 away from the rotating seat 12, and is slidably mounted at the first through hole 211. The locking block 223 is mounted on the portion of the handle 221 corresponding to the first through hole 211, and has a second locking portion 2231 that engages with the first locking portion 121. With this configuration, the size of the handle 221 is not limited by the size of the mounting member 21, allowing the handle 221 to be larger and easier for the user to operate. Of course, in other embodiments, the handle 221 can also be located on the side of the mounting member 21 facing the rotating seat 12, and a lever can be provided on the handle 221 so that the lever extends to the side of the mounting member 21 away from the rotating seat 12.

[0062] Optionally, both the first snap-fit ​​portion 121 and the second snap-fit ​​portion 2231 are provided with guide slopes to facilitate snapping the second snap-fit ​​portion 2231 into the first snap-fit ​​portion 121.

[0063] In some embodiments, the unlocking member 22 has a pull ring at one end away from the first rotation axis. The pull ring is located on the side of the mounting member 21 opposite to the rotating seat 12, and the mounting member 21 has a clearance space 212 corresponding to the position of the pull ring. This allows the user to pull the handle 221 by inserting their finger into the inner hole of the pull ring portion 2211. The large force-bearing area reduces hand pressure during operation and prevents slippage. By providing the clearance space 212 in the mounting member 21, the mounting member 21 can be prevented from obstructing the user's finger, ensuring that the user can fully insert their finger into the pull ring portion 2211 to better hook the pull ring portion 2211, facilitating user operation. Optionally, the pull ring is spaced apart from the free end face of the mounting member 21 when in the unlocked position.

[0064] In some embodiments, the elastic element 23 is disposed within the first through hole 211, and the locking block 223 has a blocking portion 2232 located on the side of the mounting member 21 facing the rotating seat 12 and covering the first through hole 211. Specifically, the first through hole 211 is elongated, and its length direction is consistent with the sliding direction of the unlocking member 22. The length of the portion of the handle 221 or the locking block 223 located within the first through hole 211 along the sliding direction of the unlocking member 22 is less than the length of the first through hole 211, so the handle 221 can cover the first through hole 211. By disposing of the elastic element 23 within the first through hole 211 and covering the first through hole 211 with the blocking portion 2232 on the locking block 223, the elastic element 23 can be hidden inside, reducing the risk of the elastic element 23 falling out and preventing sand and gravel from entering the first through hole 211 and affecting the elastic element 23, thus improving the reliability of the locking mechanism. Optionally, the elastic element 23 can be a compression spring 26, a sheet, or a rubber block, etc.

[0065] In some embodiments, the mounting base 11 has an insertion hole 111, a first hinge portion 112, and two locking portions 113. The two locking portions 113 are located on one side of the insertion hole 111 and are spaced apart. The gap between the two locking portions 113 extends to the inner wall of the insertion hole 111, so that the mounting base 11 is annular with openings at the two locking portions 113. The two locking portions 113 are connected by a second screw. The mounting member 21 is rotatably mounted on the two locking portions 113. The first rotating portion 126 is located on the side of the insertion hole 111 away from the two locking portions 113 and is hinged to the mounting base 11. That is, the first mounting position has an insertion hole 111. When used for an electric scooter, the upper end of the front fork 70 is inserted into the insertion hole 111, and the two locking portions 113 are locked by the second screw, so that the mounting base 11 is locked to the upper end of the front fork 70. This facilitates the installation of the mounting base 11 and the fork 70, and also allows for the installation of the snap-fit ​​mechanism using the two locking parts 113, thereby improving the structural compactness of the folding mechanism.

[0066] In some embodiments, the rotating base 12 is provided with a plug-in portion 122 and a second hinge portion 123. The plug-in portion 122 is used to plug into the lower end of the vertical tube 43 of the electric scooter, and the second hinge portion 123 is located on one side of the plug-in portion 122 and is hinged to the first hinge portion 112. That is, the second mounting position is provided with the plug-in portion 122. When used for an electric scooter, the plug-in portion 122 is plugged into the vertical tube 43, which allows for a larger connection area between the rotating base 12 and the vertical tube 43, improving the connection reliability. Optionally, the side of the plug-in portion 122 is provided with a plurality of third screw holes, and the vertical tube 43 is provided with a third through hole for each third screw hole, so that a locking screw can lock the plug-in portion 122 and the vertical tube 43 together.

[0067] This utility model also proposes an electric scooter, as shown in the reference. Figures 6 to 10 The electric scooter includes a pedal assembly 30, a front fork 70, a handlebar assembly 40, and a folding mechanism. The specific structure of the folding mechanism is as described in the above embodiments. Since this electric scooter adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. Specifically, the front fork 70 is rotatably mounted on the front end of the pedal assembly 30, the fixed seat 11 of the folding mechanism is mounted on the upper end of the front fork 70, and the rotating seat 12 of the folding mechanism is mounted on the lower end of the handlebar assembly 40. Specifically, the handlebar assembly 40 includes a vertical tube 43 and a horizontal handlebar 41 disposed on the upper end of the vertical tube 43, and the rotating seat 12 of the folding mechanism is mounted on the lower end of the vertical tube 43.

[0068] In some embodiments, the electric scooter also includes a rear mudguard, which is mounted on the pedal assembly 30 and covers the rear wheel 62. The top of the rear mudguard has a hook 81, and the rear of the handlebars 40 has a hanging member 50. In the folded state, the hanging member 50 engages with the hook 81. This prevents the vertical tube 43 and handlebars 40 from unfolding, and allows the electric scooter to be lifted via the vertical tube 43, making it convenient for the user to carry.

[0069] In some embodiments, the handlebar 40 includes a handlebar seat 42 and a handlebar 41. One end of the handlebar seat 42 is connected to the upper end of the riser tube 43, and the other end extends toward the front side of the riser tube 43. The handlebar 41 is mounted on the handlebar seat 42 and is located in front of the riser tube 43. A hanger 50 is mounted on the handlebar seat 42 and has a suspension portion 51. The suspension portion 51 is located behind the handlebar seat 42 and extends along the length direction of the handlebar 41. The rear end faces of the suspension portion 51 and the handlebar seat 42 are spaced apart.

[0070] By arranging the suspension parts 51 at intervals behind the handlebar seat 42 and extending along the length of the handlebar 41, items can be hung using the suspension parts 51. Because the suspension parts 51 extend along the length of the handlebar 41, their size is relatively large, and their location in the middle of the handlebar 41 allows for the hanging of more items while reducing the impact on the electric scooter's balance when hanging heavy objects. This facilitates the user's hanging of personal belongings while ensuring riding safety. Furthermore, the absence of upward-extending hooks prevents clothing from being snagged during riding or getting on and off the scooter, ensuring safety.

[0071] In some embodiments, the hanger 50 further includes two connecting portions 52, which are respectively disposed on opposite sides of the handlebar 42 and extend along the length of the handlebar 42. A suspension portion 51 is connected between the two connecting portions 52. This arrangement allows for a larger contact area between the hanger 50 and the handlebar 42, improving the installation stability of the hanger 50. Of course, in other embodiments, the hanger 50 can also be fixed at the rear end of the handlebar 42.

[0072] In some embodiments, the handlebar 42 has a mounting hole 422 on its side. The end of the connecting part 52 away from the hanging part 51 extends into the handlebar 42 through the mounting hole 422 and is fixed to the handlebar 42. That is, the hanging part 50 is mainly fixed through the part of the connecting part 52 located inside the handlebar 42. This allows the hanging part 50 to be hidden inside the connecting part 52 of the handlebar 42, avoiding collisions with external objects, ensuring reliability and a better appearance. Of course, in other embodiments, the connecting part 52 can also be welded to the outside of the handlebar 42.

[0073] In some embodiments, a fixing part 423 is provided inside the handlebar 42 and inside the mounting hole 422, and the connecting part 52 is fixed to the fixing part 423. This reduces the length of the connecting part 52 inside the handlebar 42, thereby reducing the space occupied inside the handlebar 42, so as to reserve more space inside the handlebar 42 for setting up functional components such as buttons and displays.

[0074] In some embodiments, the suspension part 51 includes a support section 511 and an opening / closing section 512. The support section 511 is connected to one of the connecting parts 52 and extends along the length of the handle 41. The opening / closing section 512 is hinged to the other connecting part 52 and has a closed state overlapping the support section 511 and an open state away from the support section 511. When it is necessary to hang an object, the opening / closing section 512 can be rotated to the open state, so that an object with a closed handle, such as a plastic bag, can be hung on the support section 511. Then, the opening / closing section 512 can be rotated to the closed state to prevent the object from falling off. This makes it convenient for users to hang items and also ensures that the items are hung reliably, reducing the risk of items falling off. Of course, in other embodiments, when the suspension part 51 is connected to the two connecting parts 52 as one unit, items can also be hung by providing one or more hooks / hooks (carabiners) on the suspension part 51.

[0075] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
