[0002] Electric scooters, based on traditional human-powered scooters and equipped with an electric powertrain, are a popular choice for both transportation and recreation. They are lightweight, convenient, and easy to carry. Electric scooters on the market typically feature a folding mechanism between the stem and front fork, allowing the stem to fold over the pedals when stored. However, some existing folding mechanisms concentrate force in a single location when locked, making them prone to failure after extended use and resulting in poor reliability.

[0008] A handlebar assembly comprises a vertical tube, the lower end of which is connected to the rotating seat;

[0009] The electric scooter has a folded state and a use state. In the use state, the rotating seat is stacked on the fixed seat, the locking mechanism is engaged with the rotating seat, and the limiter abuts against the side of the abutting portion facing the fixed seat. In the folded state, the locking mechanism is separated from the rotating seat, and the vertical tube is placed horizontally above the pedal assembly.

[0010] Optionally, the rotation axis between the fixed seat and the rotating seat is parallel to the first rotation axis.

[0013] Optionally, the rotating shaft is provided with an adjusting screw hole, and the limiting column is screwed into the adjusting screw hole.

[0014] Optionally, an abutment surface is provided at one end of the limiting column away from the rotating shaft, and the abutment surface is in the form of a convex spherical surface.

[0015] Optionally, a rotating portion is provided on the front side of the rotating seat, the rotating shaft is installed on the rotating portion, and the limiting member has a first state in which the limiting column is parallel to the front side and a second state in which the limiting column is inclined relative to the front side; the folding mechanism also includes a spring, which is connected between the rotating shaft and the rotating seat and has elastic deformation that drives the limiting member to move from the first state to the second state.

[0016] Optionally, the abutting portion is provided with an accommodating groove, and in the use state, the free end of the limiting member abuts against the accommodating groove.

[0017] Optionally, the first clamping portion is spaced apart and located at a side of the limiting member away from the fixing seat, and the second clamping portion is spaced apart and located at a side of the abutting portion away from the fixing seat.

[0018] Optionally, the locking mechanism includes a mounting member, an unlocking member and an elastic member, the mounting member is rotatably mounted on the fixing seat, the unlocking member is movably mounted on the mounting member, and has a clamping position and an unlocking position, the elastic member is arranged between the mounting member and the unlocking member, and has elastic deformation that drives the unlocking member to move from the unlocking position toward the clamping position, the unlocking member has the second clamping portion, and the mounting member has the abutting portion; in the usage state, the unlocking member is in the clamping position, and the second clamping portion is clamped with the first clamping portion.

[0019] Optionally, the unlocking member is slidably mounted on the mounting member and is arranged close to the free end of the mounting member.

In a use state, the second clamping portion is engaged with the first clamping portion, and the limiting member abuts against the side of the abutting portion facing the fixed seat. In this way, the locking mechanism is restricted from rotating in a direction away from the rotating seat by the clamping engagement of the first clamping portion and the second clamping portion. In addition, the limiting member and the abutting portion press the rotating seat against the fixed seat. Compared with a method of relying on the first clamping portion and the second clamping portion to restrict the locking mechanism from rotating relative to the rotating seat while pressing the rotating seat against the fixed seat, the force between the locking mechanism and the rotating seat can be dispersed, avoiding the force being concentrated on the first clamping portion and the second clamping portion. The structure of the first clamping portion and the second clamping portion can be simplified while ensuring the reliability of the first clamping portion and the second clamping portion, thereby improving the reliability of the folding mechanism.

[0041] The present invention provides an electric scooter.

[0042] In the embodiment of the present invention, Figures 1 to 13 As shown, the electric scooter includes a pedal assembly 30, a front fork 70, a folding mechanism and a handlebar assembly 40. The front fork 70 is rotatably mounted on the front end of the pedal assembly 30; the folding mechanism includes a fixed seat 11, a rotating seat 12, a locking mechanism 20 and a limiter 25. The fixed seat 11 is fixed to the upper end of the front fork 70, and the rotating seat 12 is rotatably mounted on the rear side of the fixed seat 11. The rotating seat 12 is provided with a first clamping portion 121; the locking mechanism 20 is rotatably mounted on the front side of the fixed seat 11 and has a first rotation axis X. The inner side of the locking mechanism 20 is provided with an abutment portion 213 and a second clamping portion 2231; the limiter 25 is rotatably mounted on the front side of the rotating seat 12. The limiter 25 has at least a second rotation axis Y parallel to the first rotation axis X; the handlebar assembly 40 has a vertical tube 43, the lower end of which is connected to the rotating seat 12.

[0043] The electric scooter has a folded state and a use state. In the use state, the rotating base 12 is stacked on the fixed base 11, the locking mechanism 20 is engaged with the rotating base 12, and the limit member 25 abuts against the side of the abutting portion 213 facing the fixed base 11. In the folded state, the locking mechanism 20 is separated from the rotating base 12, and the vertical tube 43 is placed horizontally above the pedal assembly 30.

[0044] It is understood that the electric scooter further includes a front wheel 61 and a rear wheel 62, etc. The front wheel 61 is mounted on the front fork 70, and the rear wheel 62 is mounted on the rear end of the pedal assembly 30. The basic structure of the electric scooter, such as the battery and the brake system, can be referred to in the prior art and will not be described in detail in the present invention.

[0045] It can be understood that the first rotation axis X and the second rotation axis Y are both virtual axes, and the inner side of the locking mechanism 20 is the side facing the rotating base 12 when in use.

[0046] The first clamping portion 121 is spaced from the abutting portion 213, and the second clamping portion 2231 is spaced from the limiting member 25. When in use, the first clamping portion 121 is clamped with the second clamping portion 2231 to limit the locking mechanism 20 from rotating in a direction away from the rotating seat 12, and the abutting portion 213 is located above the limiting member 25, that is, the abutting portion 213 can be pressed above the limiting member 25, so that the rotating seat 12 can be pressed against the fixed seat 11, avoiding a gap between the rotating seat 12 and the fixed seat 11 when in use. Compared with the method of relying on the first clamping portion 121 and the second clamping portion 2231 to limit the rotation of the locking mechanism 20 relative to the rotating seat 12 while pressing the rotating seat 12 onto the fixed seat 11, the first clamping portion 121 and the second clamping portion 2231 are clamped together to limit the locking mechanism 20 from rotating in the direction away from the rotating seat 12. In addition, the rotating seat 12 is pressed onto the fixed seat 11 by the limiting member 25 and the abutting portion 213, which can disperse the force between the locking mechanism 20 and the rotating seat 12 and avoid the force being concentrated on the first clamping portion 121 and the second clamping portion 2231. The structure of the first clamping portion 121 and the second clamping portion 2231 can be simplified while ensuring the reliability of the first clamping portion 121 and the second clamping portion 2231, thereby improving the reliability of the folding mechanism.

[0047] In some embodiments, the first clamping portion 121 is located on the front side of the rotating base 12. This allows the first clamping portion 121 to be away from the rotation axis between the fixed base 11 and the rotating base 12. This can enhance the position-limiting effect of the rotating base 12 during use and help simplify the structure of the first clamping portion 121. Of course, in other embodiments, the first clamping portion 121 can be provided on both the left and right sides of the rotating base 12, and the locking mechanism 20 can be provided with a second clamping portion 2231 corresponding to each first clamping portion 121.

[0048] In some embodiments, the rotation axis between the fixed seat 11 and the rotating seat 12 is parallel to the first rotation axis X. Specifically, when in use, the first clamping portion 121 abuts against the side of the second clamping portion 2231 facing away from the rotating seat 12, and the second clamping portion 2231 abuts against the side of the first clamping portion 121 facing the rotating seat 12. The rotation axis between the fixed seat 11 and the rotating seat 12 and the first rotation axis X both extend in the left-right direction, and the locking mechanism 20 can rotate forward and away from the rotating seat 12. In this way, the front side of the rotating seat 12 can be better locked when in use. While ensuring the locking effect of the locking mechanism 20 on the rotating seat 12 and the fixed seat 11, the size of the folding mechanism along the front-to-back direction of the electric scooter can be reduced.

[0049] Of course, in other embodiments, the rotation axis between the fixed seat 11 and the rotating seat 12 can also be perpendicular to the first rotation axis X, the first clamping portion 121 is provided with a groove, and the second clamping portion 2231 is provided with a glass ball screw. When the locking mechanism 20 is rotated until the second clamping portion 2231 corresponds to the first clamping portion 121, the steel ball of the glass ball screw is clamped into the groove.

[0050] 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 base 12, and the end of the limiting post 252 away from the rotating shaft 251 abuts against the abutment 213. That is, the rotating shaft 251 is coaxial with the second rotating axis Y. This simplifies the structure of the limiting member 25 and also simplifies the structure on the rotating base 12 for mounting the rotating shaft 251, facilitating assembly. Of course, in other embodiments, a spherical portion may be provided at one end of the limiting member 25, and a semicircular groove may be provided on the rotating base 12. The spherical portion may be rotatably mounted within the semicircular groove, and the other end of the limiting member 25 abuts against the abutment 213.

[0051] Optionally, the rotating shaft 251 is provided with an adjustment screw hole 2511, and the limiting post 252 is threadedly connected to the adjustment screw hole 2511. In this way, the distance between the end of the limiting post 252 away from the adjustment screw hole 2511 and the rotating shaft 251 can be adjusted. During use, the limiting post 252 can be adjusted to ensure that the rotating seat 12 can be pressed tightly against the fixed seat 11 during use. This can reduce the matching accuracy requirements of the limiting member 25 and the locking mechanism 20, which is conducive to reducing production costs. In other embodiments, the rotating shaft 251 and the limiting post 252 can be integrally formed or welded together.

[0052] In some embodiments, an abutment surface 253 is provided on the end of the limiting post 252 away from the rotating shaft 251. The abutment surface 253 is configured as a convex spherical surface. Thus, when the lock is rotated until the abutment portion 213 gradually approaches the limiting post 252, the abutment surface 253 gradually contacts the abutment portion 213, and the pressure between the two gradually increases until they are properly engaged. This provides a good guiding effect during installation, ensuring that the abutment portion 213 and the limiting post 252 are accurately engaged.

[0053] In some embodiments, the front side 125 of the rotating base 12 is provided with a rotating portion 126, a rotating shaft 251 is mounted on the rotating portion 126, and the limiting member 25 has a first state in which the limiting post 252 is parallel to the front side 125 and a second state in which the limiting post 252 is inclined relative to the front 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 an elastic deformation that drives the limiting member 25 from the first state to the second state. Specifically, the fixed base 11 has a first end surface, the rotating base 12 has a second end surface, and the front side 125 is adjacent to the second end surface. In the use state, the second end surface and the first end surface are stacked together.

[0054] In the folded state, and with the limiter 25 unaffected by external forces, the spring 26 forces the limiter 25 into the second state. When the rotating seat 12 is rotated to overlap the fixed seat 11, and the locking mechanism 20 is rotated to gradually approach the rotating seat 12, the abutment 213 gradually contacts the limiter post 252. As the locking mechanism 20 rotates, the limiter post 252 is gradually driven to rotate to the first state. At this point, the first engaging portion 121 engages the second engaging portion 2231, and the folding mechanism is in the use state. This ensures that each time the folding mechanism is switched from the folded state to the use state, the abutment 213 gradually contacts the limiter post 252 until they are properly engaged, ensuring a secure installation.

[0055] Optionally, the spring 26 is a torsion spring and is sleeved on the rotating shaft 251 , which can simplify the installation structure of the spring 26 .

[0056] In some embodiments, the abutment portion 213 is provided with a receiving groove. In the use state, the free end of the stopper 25 abuts within the receiving groove. This allows the stopper 25 to be positioned and restrained during the transition from the folded state to the use state, preventing the stopper 25 from shaking during the transition between the contact between the abutment portion 213 and the stopper 25 and the engagement between the first engaging portion 121 and the second engaging portion 2231 of the locking mechanism 20. This ensures the stability of the stopper 25 during the transition. Furthermore, the stopper 25 can be restrained in the use state, ensuring its stable installation.

[0057] In some embodiments, the first engaging portion 121 is spaced apart from the retaining member 25 on a side away from the fixed seat 11, and the second engaging portion 2231 is spaced apart from the abutting portion 213 on a side away from the fixed seat 11. That is, the abutting portion 213 is located between the second engaging portion 2231 and the fixed seat 11, and when in use, the retaining member 25 is located between the first engaging portion 121 and the fixed seat 11. It will be understood that, when in use, the mating structure of the abutting portion 213 and the retaining member 25 is the primary force-bearing position that maintains the rotating seat 12 in the use state. By placing the abutting portion 213 and the retaining member 25 close to the first rotation axis X, the stability of the abutting portion 213 and the retaining member 25 can be ensured.

[0058] 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 fixing seat 11. The unlocking member 22 is movably mounted on the mounting member 21 and has a clamping position and an unlocking position. The elastic member 23 is arranged between the mounting member 21 and the unlocking member 22 and has an elastic deformation that drives the unlocking member 22 to move from the unlocking position toward the clamping position. The unlocking member 22 has a second clamping portion 2231, and the mounting member 21 has a contact portion 213; in use, the unlocking member 22 is in the clamping position, and the second clamping portion 2231 is clamped with the first clamping portion 121.

[0059] Specifically, the unlocking member 22 is slidably mounted on the mounting member 21 and positioned near the free end of the mounting member 21. The unlocking member 22 slides perpendicularly to the rotating axis 251 of the mounting member 21, and the unlocking position is further away from the rotating axis 251 of the mounting member 21 than the engaging position. In other words, the length of the mounting member 21 is perpendicular to the first rotating axis 251, and the unlocking member 22 slides along the length of the mounting member 21. This reduces the width of the latch mechanism 20. When used on an electric scooter, this reduces the left-right dimension of the latch mechanism 20.

[0060] In the use state, the second engaging portion 2231 abuts against the side of the first engaging portion 121 facing the first rotation axis X, and the first engaging portion 121 abuts against the side of the second engaging portion 2231 facing the mounting member 21. The elastic member 23 maintains the unlocking member 22 in the engaged state between the second engaging portion 2231 and the first engaging portion 121. To switch from the use state to the folded state, the unlocking member 22 can be pulled from the side of the mounting member 21 facing away from the rotating base 12, moving the unlocking member 22 to a position where the second engaging portion 2231 is away from the first engaging portion 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.

[0061] On the contrary, when switching from the folded state to the use state, first rotate the rotating seat 12 to be stacked above the fixed seat 11, and then rotate the mounting member 21 so that the mounting member 21 is close to the rotating seat 12, pull the unlocking member 22 from the side of the mounting member 21 away from the rotating seat 12, so that the unlocking member 22 moves to a position where the second clamping portion 2231 is staggered with the first clamping portion 121. After the mounting member 21 is rotated into place, release the unlocking member 22. Under the action of the elastic member 23, the unlocking member 22 can be moved to a position where the second clamping portion 2231 is clamped with the first clamping portion 121, thereby completing the switching of the use state.

[0062] In this way, when used in an electric scooter, it can not only ensure the reliability of the structure and prevent the locking mechanism 20 from being easily opened, but also make the locking mechanism 20 and the unlocking member 22 located at the front side, so that the user can easily and directly observe the unlocking member 22 when the user needs to switch the state, and can accurately operate the unlocking member 22, reducing the time of groping and making it more convenient for the user to use.

[0063] Of course, in other embodiments, the sliding direction of the unlocking member 22 can also be parallel to the first rotation axis X; or, the unlocking member 22 is rotatably mounted on the mounting member 21, and the rotation axis of the unlocking member 22 is perpendicular to the first rotation axis X and the length direction of the mounting member 21.

[0064] In some embodiments, the end of the unlocking member 22 distal from the first rotation axis X is no higher than the free end of the mounting member 21. Specifically, even when the unlocking member 22 is moved to its furthest position from the first rotation axis X, the end of the unlocking member 22 distal from the first rotation axis X remains 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 user's application of force when pulling the unlocking member 22 and facilitating user operation. This also prevents the end of the unlocking member 22 distal from the first rotation axis X from being easily impacted when it is elevated above the free end of the mounting member 21, thereby reducing the risk of damage to the unlocking member 22 during use and improving the reliability of the unlocking member 22. Of course, in other embodiments, when the unlocking member 22 is moved to its furthest position from the first rotation axis X, the unlocking member 22 may extend beyond the free end of the mounting member 21.

[0065] Optionally, the width of the unlocking member 22 is smaller than the width of the mounting member 21, that is, the orthographic projection of the unlocking member 22 on the mounting member 21 is located on the mounting member 21 as a whole. In this way, the unlocking member 22 can be protected by the mounting member 21, reducing the risk of the unlocking member 22 being deformed by collision and affecting normal sliding, thereby improving the reliability of the unlocking member 22.

[0066] 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 latch 223. The handle 221 is plate-shaped and located on the side of the mounting member 21 facing away from the rotating seat 12, and is slidably mounted on the first through-hole 211. The latch 223 is mounted on the portion of the handle 221 corresponding to the first through-hole 211 and has a second latching portion 2231 that engages with the first latching portion 121. With this arrangement, 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 more convenient for user operation. 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, extending to the side of the mounting member 21 facing away from the rotating seat 12.

[0067] Optionally, both the first clamping portion 121 and the second clamping portion 2231 are provided with guiding inclined surfaces to facilitate clamping the second clamping portion 2231 with the first clamping portion 121 .

[0068] In some embodiments, a pull ring is provided at one end of the unlocking member 22 away from the first rotation axis X. The pull ring is located on the side of the mounting member 21 facing away from the rotating base 12, and a clearance space 212 is provided on the mounting member 21 corresponding to the pull ring. That is, the user can pull the handle 221 by inserting a finger into the inner hole of the pull ring portion 2211. This has a large force-bearing area, which can reduce the pressure on the user's hand during operation and prevent the hand from slipping during operation. By providing the clearance space 212 on the mounting member 21, the mounting member 21 can be prevented from blocking 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, thereby facilitating user operation. Optionally, when the pull ring is in the unlocked position, it is spaced apart from the free end face of the mounting member 21.

[0069] In some embodiments, the elastic member 23 is disposed within the first through-hole 211, and the block 223 has a shielding portion 2232. The shielding portion 2232 is located on the side of the mounting member 21 facing the rotating seat 12 and covers the first through-hole 211. Specifically, the first through-hole 211 is elongated, with its length aligning with the sliding direction of the unlocking member 22. The length of the handle 221 or the portion of the block 223 located within the first through-hole 211 along the sliding direction of the unlocking member 22 is shorter than the length of the first through-hole 211, allowing the handle 221 to cover the first through-hole 211. By disposing the elastic member 23 within the first through-hole 211 and using the shielding portion 2232 on the block 223 to cover the first through-hole 211, the elastic member 23 can be concealed, reducing the risk of the elastic member 23 falling out and preventing sand and gravel from entering the first through-hole 211 and affecting the elastic member 23, thereby improving the reliability of the latching mechanism. Optionally, the elastic member 23 is a compression spring 26 , a spring 531 , a rubber block, or the like.

[0070] In some embodiments, the fixing base 11 comprises an insertion hole 111, a first hinged 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 fixing base 11 is in the shape of a ring with an opening 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 hingedly connected to the fixing base 11. That is, the first mounting position is provided with an insertion hole 111. When used in 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 fixing base 11 is locked to the upper end of the front fork 70. This not only facilitates the installation of the fixing base 11 and the front fork 70 , but also allows the two locking portions 113 to be used to install the clamping mechanism, thereby improving the structural compactness of the folding mechanism.

[0071] In some embodiments, the rotating base 12 is provided with a plug-in portion 122 and a second hinged portion 123. The plug-in portion 122 is configured to be plugged into the lower end of the vertical tube 43 of the electric scooter. The second hinged portion 123 is located on one side of the plug-in portion 122 and is hingedly connected to the first hinged portion 112. Specifically, the plug-in portion 122 is provided at the second mounting position. When used on an electric scooter, the plug-in portion 122 is plugged into the vertical tube 43. This allows for a larger connection area between the rotating base 12 and the vertical tube 43, improving connection reliability. Optionally, a plurality of third screw holes are provided on the side of the plug-in portion 122. The vertical tube 43 is provided with a third through hole corresponding to each third screw hole, for a locking screw to secure the plug-in portion 122 to the vertical tube 43.

[0072] In some embodiments, the electric scooter further includes a rear fender mounted on the pedal assembly 30 and positioned over the rear wheel 62. A hook 81 is provided on the top of the rear fender, and a hanger 50 is provided on the rear side of the handlebar 40. When folded, the hanger 50 engages with the hook 81. This prevents the vertical tube 43 and handlebar 40 from unfolding, and allows the electric scooter to be carried by the vertical tube 43, making it easier for the user to carry the scooter.

[0073] In some embodiments, the handlebar 40 includes a handlebar base 42 and a horizontal handlebar 41. One end of the handlebar base 42 is connected to the upper end of the vertical tube 43, and the other end extends toward the front side of the vertical tube 43. The horizontal handlebar 41 is installed on the handlebar base 42 and is located in front of the vertical tube 43. The hanger 50 is installed on the handlebar base 42 and has a hanging portion 51. The hanging portion 51 is located on the rear side of the handlebar base 42 and extends along the length direction of the horizontal handlebar 41. The hanging portion 51 is spaced apart from the rear end surface 421 of the handlebar base 42.

[0074] By positioning the hanging portion 51 at intervals behind the handlebar 42 and extending along the length of the handlebar 41, items can be hung from the hanging portion 51. Since the hanging portion 51 extends along the length of the handlebar 41, the hanging portion 51 can be larger. Furthermore, the hanging portion 51 is located in the middle of the handlebar 41, allowing for more items to be hung while minimizing the impact on the balance of the electric scooter when heavier objects are hung. This makes it easier for users to hang their belongings while ensuring safe riding. Furthermore, the lack of an upwardly extending hook prevents clothing from getting caught during riding or when getting on and off the scooter, ensuring safe use.

[0075] In some embodiments, the hanger 50 further includes two connecting portions 52, which are disposed on opposite sides of the handlebar base 42 and extend along the length of the handlebar base 42. The hanging 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 base 42, thereby improving the installation stability of the hanger 50. Of course, in other embodiments, the hanger 50 can also be fixed to the rear end of the handlebar base 42.

[0076] In some embodiments, a mounting hole 422 is provided on the side of the handlebar base 42. The end of the connecting portion 52, distal from the hanging portion 51, extends through the mounting hole 422 into the handlebar base 42 and is secured to the handlebar base 42. Specifically, the hanger 50 is primarily secured by the portion of the connecting portion 52 located within the handlebar base 42. This allows the connecting portion 52 between the hanger 50 and the handlebar base 42 to be hidden internally, preventing collision with external objects. This ensures both reliability and a better appearance. Of course, in other embodiments, the connecting portion 52 can also be welded to the outside of the handlebar base 42.

[0077] In some embodiments, a fixing portion 423 is provided inside the handle base 42 and inside the mounting hole 422, and the connecting portion 52 is fixed to the fixing portion 423. This can reduce the length of the connecting portion 52 inside the handle base 42 and the space occupied by the handle base 42, thereby reserving more space inside the handle base 42 for functional components such as buttons and a display screen.

[0078] In some embodiments, the fixing portion 423 is provided with a concave arc surface 424, which is aligned with the inner wall surface of the mounting hole 422, and the connecting portion 52 is fixed at the concave arc surface 424.

[0079] This increases the contact area between the concave arc surface 424 and the connecting portion 52, thereby improving the connection stability between the connecting portion 52 and the fixing portion 423. Optionally, the connecting portion 52 is fixed to the fixing portion 423 via a locking screw, which ensures connection stability while facilitating assembly. Of course, in other embodiments, the connecting portion 52 may also be welded to the fixing portion 423.

[0080] In some embodiments, a limiting groove 425 is provided on the side of the handlebar 42, and the limiting groove 425 extends along the length direction of the handlebar 42, and the connecting portion 52 is located in the limiting groove 425. Specifically, when a heavy object is hung on the hanging portion 51, the connecting portion 52 deforms downward and can abut against the lower side wall of the limiting groove 425, that is, the connecting portion 52 can be supported by the lower side wall of the limiting groove 425, thereby reducing the deformation of the connecting portion 52 when hanging a heavy object and improving the load-bearing capacity and reliability of the hanging component 50. Specifically, when no heavy object is hung, the connecting portion 52 and the side wall (upper side wall or lower side wall) of the limiting groove 425 can abut against each other, or can be separated by a certain distance (which can reduce the matching accuracy).

[0081] In some embodiments, the hanging portion 51 includes a support section 511 and an opening and closing section 512. The support section 511 is connected to one of the connecting portions 52 and extends along the length of the horizontal handle 41. The opening and closing section 512 is hinged to the other connecting portion 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 and 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, and then the opening and closing section 512 is 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 hanging portion 51 is connected to the two connecting portions 52 as one body, items can also be hung by providing one or more hooks / hooks (climbing buckles) on the hanging portion 51.

[0082] In some embodiments, the end of the opening and closing section 512 is provided with two mounting portions 512c and a receiving hole 512d located between the two mounting portions 512c, and the receiving hole 512d extends along the length direction of the opening and closing section 512. The connecting portion 52 is hinged between the two mounting portions 512c, and a limiting slot 521 is provided at the end of the connecting portion 52 corresponding to the receiving hole 512d. The hanger 50 also includes an elastic component 53, which is located in the receiving hole 512d and has a spring piece 531 extending into the limiting slot 521. The spring piece 531 has elastic deformation that drives the opening and closing section 512 to move from an open state to a closed state. That is, the opening and closing section 512 can be kept in a closed state by the elastic component 53, and when the opening and closing section 512 is opened to the open state, the opening and closing section 512 can also be restored to the closed state under the action of the elastic component 53 after the hand is released, which can avoid the situation of manually switching the opening and closing section 512 to the closed state, and can also avoid the opening and closing section 512 automatically opening during driving, and has high reliability.

[0083] Optionally, the hanger 50 also includes a limit spring 5426, which is sleeved on the limit component. One end of the limit spring 5426 abuts against the hole wall of the accommodating hole 512d away from the limit slot 521, and the other end abuts against the spring piece 531. In this way, the limit spring 5426 can be used to press the spring piece 531 tightly in the limit slot 521, so as to better keep the opening and closing section 512 in a closed state.

[0084] In some embodiments, a first engaging groove 511a is provided on the upper side of the support section 511, and the first engaging groove 511a extends to the end surface of the support section 511. A first engaging portion 512a is provided at the end of the opening and closing section 512. The rotation axis 251 of the opening and closing section 512 extends along the length of the horizontal handlebar 41. In the closed state, the first engaging portion 512a is located within the first engaging groove 511a. Specifically, the notch of the first engaging groove 511a faces upward, and the bottom wall of the first engaging groove 511a opposite the notch is spaced from the lower side of the support section 511. The first engaging groove 511a penetrates the end surface of the support section 511, and the first engaging portion 512a is located above the end of the opening and closing section 512 and spaced from the lower side of the end of the opening and closing section 512. In the closed state, the support section 511 can limit the downward rotation of the opening and closing section 512, and the first latching slot 511a can limit the horizontal rotation of the opening and closing section 512, so that the opening and closing section 512 can be stably maintained in the closed state, reducing the possibility of the opening and closing section 512 opening due to accidental operation. Of course, in other embodiments, a limiting portion can also be provided on the connecting portion 52, so that the limiting portion extends to the lower side of the hinged end of the opening and closing section 512. In the closed state, the opening and closing section 512 abuts against the upper side of the limiting portion to limit the downward rotation of the opening and closing section 512.

[0085] Optionally, a second engaging groove 511b is further provided on the upper side of the support section 511. The second engaging groove 511b extends in the radial direction of the support section 511. The first engaging groove 511a extends from the second engaging groove 511b to the end surface of the support section 511. A second engaging portion 512b is provided at the end of the first engaging portion 512a distal from the hinged end of the closing section 512. In the closed state, the second engaging portion 512b engages with the second engaging groove 511b. This further restricts the swinging of the opening and closing section 512 in the closed state, allowing the opening and closing section 512 to remain stably in the closed state.

[0086] In some embodiments, the rear end surface 421 of the handlebar base 42 is a convex arc, with the generatrix of the convex arc extending along the length of the riser 43. The hanging portion 51 is in the shape of an arc that convexly rises away from the handlebar base 42. This prevents sharp corners in the hanging portion 51, ensuring safety in use. It also allows for a wider gap between the hanging portion 51 and the rear end surface 421 of the handlebar base 42, making it easier to hang a variety of items.
