[0041] The present invention provides a folding mechanism for an electric scooter.

[0042] In the embodiment of the present invention, Figures 1 to 14 As shown, the folding mechanism includes a folding seat 10 and a clamping mechanism 20, wherein the folding seat 10 includes a first part 11 and a second part 12, one side of the first part 11 and the second part 12 are hinged to each other and have a first rotation axis X, and the side of the second part 12 away from the first rotation axis X is provided with a first clamping portion 121.

[0043] The clamping mechanism 20 includes a mounting member 21, an unlocking member 22 and an elastic member 23. The mounting member 21 is hinged to the other side of the first part 11 and has a second rotation axis Y parallel to the first rotation axis X. The unlocking member 22 is slidably mounted on the mounting member 21 and is exposed on the side of the mounting member 21 facing away from the second part 12. The elastic member 23 is connected between the mounting member 21 and the unlocking member 22 and has elastic deformation that drives the unlocking member 22 to move toward the second rotation axis Y.

[0044] The folding mechanism has a use state in which the first part 11 and the second part 12 are stacked and a folding state in which the first part 11 and the second part 12 are unfolded. In the use state, the mounting member 21 is close to the side of the second part 12 away from the first rotation axis X, and the unlocking member 22 is clamped to the first clamping portion 121.

[0045] It will be understood that the first rotation axis X and the second rotation axis Y are both virtual axes. The first portion 11 has a first mounting position, through which it is fixed to the upper end of the front fork 70 of the electric scooter. The first rotation axis X and the second rotation axis Y are located on opposite sides of the first mounting position. That is, the mounting member 21 is located on the side of the first portion 11 away from the first rotation axis X. The second portion 12 has a second mounting position, through which it is connected to the lower end of the vertical tube 30 of the electric scooter. The first clamping portion 121 and the first rotation axis X are located on opposite sides of the first mounting position. When in use, the second portion 12 is stacked on the first portion 11, thereby positioning the vertical tube 30 upright above the front fork 70. When folded, the second portion 12 rotates to one side of the first portion 11, positioning the vertical tube 30 horizontally above the pedal assembly 90 of the electric scooter.

[0046] In this embodiment, the length of the mounting member 21 is perpendicular to the second rotation axis, and the unlocking member 22 is slidably mounted on the mounting member 21 along the length of the mounting member 21. This reduces the width of the engaging mechanism 20 and, when mounted on an electric scooter, reduces the left-right dimension of the engaging mechanism 20. Of course, in other embodiments, the direction of movement of the unlocking member 22 can also be parallel to the second rotation axis.

[0047] The unlocking member 22 has a second engaging portion 2231. In the use state, the second engaging portion 2231 abuts the side of the first engaging portion 121 facing the first rotation axis X, and the first engaging portion 121 abuts 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 second base, 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 second portion 12, thereby rotating the second portion 12 and switching the folding mechanism to the folded state. On the contrary, when switching from the folded state to the use state, first rotate the second part 12 to stack on top of the first part 11, and then rotate the mounting member 21 so that the mounting member 21 is close to the second part 12, pull the unlocking member 22 from the side of the mounting member 21 away from the second base body, 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.

[0048] The technical solution of the present invention is to hinge the first part 11 and one side of the second part 12 of the folding seat 10 to each other, set a clamping mechanism 20 on the other side of the first part 11, and set a first clamping portion 121 on the other side of the second part 12, and make the unlocking member 22 on the clamping mechanism 20 for unlocking operation appear on the side of the mounting member 21 away from the second part 12. In this way, when used for an electric scooter, the clamping mechanism 20 and the unlocking member 22 can be located on the front side, so that the user can easily and directly observe the unlocking member 22 when switching states, and can accurately operate the unlocking member 22, reducing the time of groping and making it convenient for users to use.

[0049] In some embodiments, the end of the unlocking member 22 distal from the second rotation axis Y is no higher than the free end of the mounting member 21. Specifically, even when the unlocking member 22 is moved to the position farthest from the second rotation axis Y, the end of the unlocking member 22 distal from the second rotation axis Y 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 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 second rotation axis Y 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 the position farthest from the second rotation axis Y, the unlocking member 22 may extend beyond the free end of the mounting member 21.

[0050] 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.

[0051] 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 second portion 12. It 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. This arrangement allows the size of the handle 221 to be unrestricted by the size of the mounting member 21, allowing for a larger size and easier operation for the user. Of course, in other embodiments, the handle 221 can be located on the side of the mounting member 21 facing the second portion 12, and a lever can be provided on the handle 221, extending to the side of the mounting member 21 facing away from the second portion 12.

[0052] 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 .

[0053] In some embodiments, the handle 221 includes a ring pull portion 2211, and the mounting member 21 is provided with an escape space 212 at a position corresponding to the ring pull portion 2211. This allows the user to pull the handle 221 by inserting a finger into the inner hole of the ring pull portion 2211. This provides a large force-bearing area, reduces pressure on the user's hand during operation, and prevents hand slippage during operation. Providing the escape space 212 on the mounting member 21 prevents the mounting member 21 from blocking the user's finger, ensuring that the user can fully insert their finger into the ring pull portion 2211 to better hook the ring pull portion 2211, facilitating user operation.

[0054] In some embodiments, the free end of the mounting member 21 gradually extends in an inclined manner toward the side where the handle 221 is located in a direction away from the second rotation axis Y. That is, the free end of the mounting member 21 gradually bends in a direction away from the second portion 12. This effectively shields the unlocking member 22, reducing the risk of damage to the unlocking member 22. It also increases the lateral width (perpendicular to the second rotation axis Y and the sliding direction of the unlocking member 22) of the free end of the unlocking member 22. When the user pulls the unlocking member 22, the hand abuts against the free end of the mounting member 21 and deforms, which increases the contact area between the hand and the free end of the mounting member 21, thereby providing better support.

[0055] In some embodiments, the elastic member 23 is disposed within the first through-hole 211, and the latch 223 has a shielding portion 2232. The shielding portion 2232 is located on the side of the mounting member 21 facing the second portion 12 and covers the first through-hole 211. Specifically, the first through-hole 211 is elongated, its length aligning with the sliding direction of the unlocking member 22. The length of the handle 221 or the portion of the latch 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 latch 223 to cover the first through-hole 211, the elastic member 23 is 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 20. Optionally, the elastic member 23 is a compression spring, a spring 531 or a rubber block, etc.

[0056] In some embodiments, the handle 221 has a sliding portion 2212 that is slidably mounted within the first through-hole 211, and the clamp 223 is mounted on the sliding portion 2212. This allows the sliding portion 2212 to be inserted into the first through-hole 211 during installation to pre-position the handle 221. This also increases the structural strength of the handle 221 at the location of the sliding portion 2212, ensuring stable installation of the clamp 223.

[0057] Optionally, the sliding portion 2212 is provided with a plurality of first screw holes 2213, and the clamping block 223 is provided with a second through hole 2233 at a position corresponding to each first screw hole 2213. The clamping mechanism 20 further includes a first screw 24, the screw rod of the first screw 24 passes through the second through hole 2233 and is screwed into the first screw hole 2213. This ensures that the clamping block 223 is securely mounted and facilitates installation of the clamping mechanism 20.

[0058] Optionally, a countersunk hole is provided on a side of the clamping block 223 away from the sliding portion 2212 , and the head of the first screw 24 is located in the countersunk hole.

[0059] In some embodiments, a recess is provided on the side of the handle 221 facing the first through-hole 211, and the elastic member 23 is located in the recess. This can increase the installation space of the elastic member 23 and enable the use of a larger elastic member 23, thereby providing the elastic member 23 with better elastic deformation ability and ensuring the reliable use of the clamping mechanism 20.

[0060] In some embodiments, the first portion 11 has a socket 111, a first hinged portion 112, and two locking portions 113. The two locking portions 113 are located on one side of the socket 111 and are spaced apart. The gap between the two locking portions 113 extends to the inner wall of the socket 111, so that the first portion 11 is annular and opens 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 is located on the side of the socket 111 away from the two locking portions 113 and is hingedly connected to the first portion 11. That is, the first mounting position is provided with a socket 111. When used in an electric scooter, the upper end of the front fork 70 is inserted into the socket 111, and the two locking portions 113 are locked by the second screw, so that the first portion 11 is locked to the upper end of the front fork 70. This not only facilitates the installation of the first portion 11 and the front fork 70 , but also allows the two locking portions 113 to be used to install the clamping mechanism 20 , thereby improving the structural compactness of the folding mechanism.

[0061] In some embodiments, the second portion 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 30 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 30. This increases the connection area between the second portion 12 and the vertical tube 30 and improves connection reliability. Optionally, the plug-in portion 122 is provided with a plurality of third screw holes on the side surface. The vertical tube 30 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 30.

[0062] In some embodiments, first avoidance grooves 114 are respectively provided on opposite sides of the first hinged portion 112, and the second hinged portion 123 extends toward the second part 12 away from the plug-in portion 122, and is provided with a second avoidance groove 124. The first hinged portion 112 is hinged in the second avoidance groove 124, which can improve the structural compactness of the hinged part of the first part 11 and the second part 12, which is conducive to reducing the size of the folding mechanism.

[0063] The present invention also provides an electric scooter, referring to Figures 7 to 14 The electric scooter includes a pedal assembly 90, a front fork 70, a stem 30, a handlebar 40, and a folding mechanism. The specific structure of the folding mechanism is similar to that of the above embodiments. Since the 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. Among them, the front fork 70 is rotatably mounted on the front end of the pedal assembly 90, the first part 11 of the folding mechanism is mounted on the upper end of the front fork 70, the second part 12 of the folding mechanism is mounted on the lower end of the stem 30, and the handlebar 40 assembly is mounted on the upper end of the stem 30.

[0064] In some embodiments, the electric scooter further includes a rear fender mounted on the pedal assembly 90 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 riser 30 and handlebar 40 from unfolding, and allows the electric scooter to be carried by the riser 30, making it easier for the user to carry the scooter.

[0065] 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 30, and the other end extends toward the front side of the vertical tube 30. The horizontal handlebar 41 is mounted on the handlebar base 42 and is located on the front side of the vertical tube 30. The hanger 50 is mounted 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] In some embodiments, the fixing portion 423 is provided with a concave arc surface 424 that is aligned with the inner wall of the mounting hole 422, and the connecting portion 52 is fixed to the concave arc surface 424. This increases the contact area between the concave arc surface 424 and the connecting portion 52, thereby improving the stability of the connection 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 can also be welded to the fixing portion 423.

[0071] 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).

[0072] 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.

[0073] In some embodiments, the opening and closing section 512 includes two mounting portions 512c at its end and a receiving hole 512d located between the two mounting portions 512c. The receiving hole 512d extends along the length of the opening and closing section 512. The connecting section is hinged between the two mounting portions 512c. A limiting slot 521 is provided at the end of the connecting section corresponding to the receiving hole 512d. The hanger 50 further includes an elastic member 53 located within the receiving hole 512d and having a spring 531 extending into the limiting slot 521. The spring 531 is elastically deformable to force the opening and closing section 512 from the open state to the closed state. In other words, the elastic member 53 maintains the opening and closing section 512 in the closed state. When the opening and closing section 512 is opened to the open state, the elastic member 53 returns to the closed state upon release of the user's hand. This prevents the opening and closing section 512 from being manually switched to the closed state and prevents the opening and closing section 512 from automatically opening during driving, thereby enhancing reliability.

[0074] Optionally, the hanger 50 also includes a limit spring 54, which is sleeved on the limit component. One end of the limit spring 54 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 54 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.

[0075] 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 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, 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.

[0076] 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.

[0077] 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 30. 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.

[0078] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
