[0041] This utility model proposes a folding mechanism for electric scooters.

[0042] In the embodiments of this utility model, such as Figures 1 to 14 As shown, the folding mechanism includes a folding seat 10 and a snap-fit ​​mechanism 20. 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. The second part 12 has a first snap-fit ​​portion 121 on the side away from the first rotation axis X.

[0043] The latching 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 exposed on the side of the mounting member 21 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 usage state in which the first part 11 and the second part 12 are stacked together, and a folded state in which the first part 11 and the second part 12 are unfolded. In the usage state, the mounting part 21 is close to the side of the second part 12 away from the first rotation axis X, and the unlocking part 22 is engaged with the first engaging part 121.

[0045] It can be understood that the first rotation axis X and the second rotation axis Y are both virtual axes. The first part 11 has a first mounting position, and the first part 11 is fixed to the upper end of the front fork 70 of the electric scooter through the first mounting position. The first rotation axis X and the second rotation axis Y are respectively located on opposite sides of the first mounting position, that is, the mounting member 21 is located on the side of the first part 11 away from the first rotation axis X. The second part 12 has a second mounting position, and the second part 12 is connected to the lower end of the vertical tube 30 of the electric scooter through the second mounting position. The first snap-fit ​​part 121 and the first rotation axis X are respectively located on opposite sides of the first mounting position. In the use state, the second part 12 is stacked on the first part 11, so that the vertical tube 30 is upright above the front fork 70; while in the folded state, the second part 12 is rotated open to one side of the first part 11, so that the vertical tube 30 is placed horizontally above the pedal assembly 90 of the electric scooter.

[0046] In this embodiment, the length direction 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 its length direction. This reduces the width of the locking mechanism 20, thus reducing the size of the locking mechanism 20 in the left-right direction when mounted on an electric scooter. Of course, in other embodiments, the movement direction of the unlocking member 22 can 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 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 keeps the unlocking member 22 engaged between the second engaging portion 2231 and the first engaging portion 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 second base, causing the unlocking member 22 to move 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 part 12, thereby rotating the second part 12 and switching the folding mechanism to the folded state. Conversely, when switching from the folded state to the usage state, first rotate the second part 12 to overlap the first part 11, then rotate the mounting piece 21 so that it is close to the second part 12. Pull the unlocking piece 22 from the side of the mounting piece 21 away from the second base body so that the unlocking piece 22 moves to the position where the second locking part 2231 is misaligned with the first locking part 121. After the mounting piece 21 is rotated into place, release the unlocking piece 22. Under the action of the elastic member 23, the unlocking piece 22 can move to the position where the second locking part 2231 is engaged with the first locking part 121, thereby completing the switching of the usage state.

[0048] This utility model's technical solution hinges one side of the first part 11 and the second part 12 of the folding seat 10 together, provides a latching mechanism 20 on the other side of the first part 11, and provides a first latching part 121 on the other side of the second part 12. The unlocking part 22 on the latching mechanism 20 for unlocking operation is exposed on the side of the mounting part 21 away from the second part 12. In this way, when used for electric scooters, the latching mechanism 20 and the unlocking part 22 can be located on the front side, so that when the user needs to switch states, the unlocking part 22 can be easily observed and operated accurately, reducing the time spent on trial and error and making it convenient for the user.

[0049] In some embodiments, the end of the unlocking member 22 furthest from the second rotation axis Y 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 second rotation axis Y, the end of the unlocking member 22 furthest 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 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 second rotation axis Y, it may also extend beyond the free end of the mounting member 21.

[0050] Optionally, the width of the unlocking component 22 is smaller than the width of the mounting component 21, that is, the orthographic projection of the unlocking component 22 on the mounting component 21 is entirely located on the mounting component 21. In this way, the unlocking component 22 can be protected by the mounting component 21, reducing the risk that the unlocking component 22 will be affected by collision deformation and thus improving the reliability of the unlocking component 22.

[0051] In some embodiments, the mounting member 21 has 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 opposite to the second part 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 second part 12, and a lever can be provided on the handle 221 so that the lever extends to the side of the mounting member 21 opposite to the second part 12.

[0052] 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.

[0053] In some embodiments, the handle 221 has a pull ring portion 2211, and the mounting member 21 is provided with a clearance space 212 corresponding to the position of the pull ring portion 2211; that is, the user can pull the handle 221 by inserting his / her finger into the inner hole of the pull ring portion 2211. The large force-bearing area reduces the pressure on the user's hand during operation and also prevents the hand from slipping during operation. By providing a clearance space 212 in the mounting member 21, the mounting member 21 can be prevented from blocking the user's finger, ensuring that the user can fully insert his / her finger into the pull ring portion 2211 to better hook the pull ring portion 2211, making it convenient for the user to operate.

[0054] In some embodiments, the free end of the mounting member 21 gradually extends at an angle 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 away from the second part 12, which can better shield the unlocking member 22, reduce the risk of the unlocking member 22 being damaged, and increase the lateral width (the direction 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 contact area between the hand and the free end of the mounting member 21 is larger when the hand comes into contact with and deforms, which can provide a better support effect.

[0055] 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 second portion 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 20. Optionally, the elastic element 23 can be a compression spring, a sheet 531, or a rubber block, etc.

[0056] In some embodiments, the handle 221 has a sliding portion 2212, which is slidably installed in the first through hole 211, and the locking block 223 is installed on the sliding portion 2212. In this way, during installation, the sliding portion 2212 can be inserted into the first through hole 211 first to achieve the pre-positioning of the handle 221, and the structural strength of the position of the sliding portion 2212 on the handle 221 can be increased to ensure the stable installation of the locking block 223.

[0057] Optionally, the sliding part 2212 is provided with a plurality of first screw holes 2213, and the locking block 223 is provided with a second through hole 2233 corresponding to the position of each first screw hole 2213. The locking mechanism 20 also includes a first screw 24, the shank of the first screw 24 passing through the second through hole 2233 and screwed into the first screw hole 2213. This ensures reliable installation of the locking block 223 and facilitates the installation of the locking mechanism 20.

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

[0059] In some embodiments, the handle 221 has a relief groove on the side facing the first through hole 211, and the elastic member 23 is located in the relief groove. This increases the installation space of the elastic member 23, allowing for the use of a larger elastic member 23, so that the elastic member 23 has better elastic deformation capability, ensuring the reliable use of the snap-fit ​​mechanism 20.

[0060] In some embodiments, the first portion 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 first portion 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 hinge portion 112 is located on the side of the insertion hole 111 away from the two locking portions 113 and is hinged to the first portion 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 first portion 11 is locked to the upper end of the front fork 70. This facilitates the installation of the first part 11 and the front fork 70, and also allows the two locking parts 113 to install the snap-fit ​​mechanism 20, thereby improving the structural compactness of the folding mechanism.

[0061] In some embodiments, the second part 12 is provided with a plug-in part 122 and a second hinge part 123. The plug-in part 122 is used to plug into the lower end of the vertical tube 30 of the electric scooter, and the second hinge part 123 is located on one side of the plug-in part 122 and is hinged to the first hinge part 112. That is, the second mounting position is provided with a plug-in part 122. When used for an electric scooter, the plug-in part 122 is plugged into the vertical tube 30, which allows the connection area between the second part 12 and the vertical tube 30 to be larger, thus improving the connection reliability. Optionally, the side of the plug-in part 122 is provided with a plurality of third screw holes, and the vertical tube 30 is provided with a third through hole for each third screw hole, so that a locking screw can lock the plug-in part 122 and the vertical tube 30 together.

[0062] In some embodiments, the first hinge portion 112 is provided with first clearance grooves 114 on opposite sides, and the second hinge portion 123 extends toward the second portion 12 away from the insertion portion 122 and is provided with a second clearance groove 124. The first hinge portion 112 is hinged in the second clearance groove 124. This can improve the structural compactness of the hinge portion of the first portion 11 and the second portion 12, which is beneficial to reducing the size of the folding mechanism.

[0063] This utility model also proposes an electric scooter, as shown in the reference. Figures 7 to 14 The electric scooter includes a pedal assembly 90, a front fork 70, a vertical tube 30, handlebars 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 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 vertical tube 30, and the handlebars 40 are mounted on the upper end of the vertical tube 30.

[0064] In some embodiments, the electric scooter also includes a rear mudguard, which is mounted on the pedal assembly 90 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 30 and handlebars 40 from unfolding, and allows the electric scooter to be lifted through the vertical tube 30, making it convenient for the user to carry.

[0065] 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 30, and the other end extends toward the front side of the riser tube 30. The handlebar 41 is mounted on the handlebar seat 42 and is located in front of the riser tube 30. The 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 face 421 of the suspension portion 51 and the handlebar seat 42 are spaced apart.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] In some embodiments, the fixing part 423 has a concave arc surface 424, which is flush with the inner wall of the mounting hole 422, and the connecting part 52 is fixed at the concave arc surface 424. This allows for a larger contact area between the concave arc surface 424 and the connecting part 52, improving the connection stability between the connecting part 52 and the fixing part 423. Optionally, the connecting part 52 is fixed to the fixing part 423 by a locking screw, which ensures connection stability while facilitating assembly. Of course, in other embodiments, the connecting part 52 can also be welded to the fixing part 423.

[0071] In some embodiments, a limiting groove 425 is provided on the side of the handle 42, extending along the length of the handle 42, and the connecting part 52 is located within the limiting groove 425. Specifically, when a heavy object is hung on the suspension part 51, the connecting part 52 deforms downward and abuts against the lower side wall of the limiting groove 425. That is, the lower side wall of the limiting groove 425 can support the connecting part 52, reducing the deformation of the connecting part 52 when hanging a heavy object, and improving the load-bearing capacity and reliability of the hanger 50. When no heavy object is hung, the connecting part 52 and the side wall (upper side wall or lower side wall) of the limiting groove 425 can abut against each other, or they can be spaced a certain distance apart (which can reduce the fitting precision).

[0072] 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.

[0073] In some embodiments, the opening / closing section 512 has 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 direction of the opening / closing section 512. A connecting section is hinged between the two mounting portions 512c. A limiting groove 521 is provided at the end of the connecting section corresponding to the position of the receiving hole 512d. The hanger 50 also includes an elastic member 53, which is located within the receiving hole 512d and has a spring piece 531 extending into the limiting groove 521. The spring piece 531 has an elastic deformation that drives the opening / closing section 512 to move from the open state to the closed state. That is, the opening / closing section 512 can be held in the closed state by the elastic member 53, and when the opening / closing section 512 is opened to the open state, it can also be reset to the closed state under the action of the elastic member 53 after being released. This can avoid the need to manually switch the opening / closing section 512 to the closed state and can also prevent the opening / closing section 512 from opening automatically during driving, thus ensuring high reliability.

[0074] Optionally, the pendant 50 also includes a limiting spring 54, which is sleeved on the limiting component. One end of the limiting spring 54 abuts against the wall of the receiving hole 512d away from the limiting slot 521, and the other end abuts against the spring piece 531. In this way, the limiting spring 54 can be used to press the spring piece 531 against the limiting slot 521, thereby better keeping the opening and closing section 512 in the closed state.

[0075] In some embodiments, a first slot 511a is provided on the upper side of the support section 511, extending to the end face 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 direction of the handle 41. In the closed state, the first engaging portion 512a is located within the first slot 511a. Specifically, the opening of the first slot 511a faces upward, the bottom wall of the slot 511a opposite to the opening is spaced apart from the lower side of the support section 511, the first slot 511a penetrates the end face of the support section 511, and the first engaging portion 512a is located on the upper side of the end of the opening and closing section 512 and spaced apart from the lower side of the end of the opening and closing section 512. In the closed state, the support section 511 can restrict the downward rotation of the opening and closing section 512, while the first slot 511a can restrict the horizontal rotation of the opening and closing section 512, so that the opening and closing section 512 can be stably kept 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 part can also be provided in the connecting part 52, so that the limiting part extends to the lower side of the hinge end of the opening and closing section 512. In the closed state, the opening and closing section 512 abuts against the upper part of the limiting part to restrict the downward rotation of the opening and closing section 512.

[0076] Optionally, a second slot 511b is also provided on the upper side of the support section 511. The second slot 511b extends radially along the support section 511, and the first slot 511a extends from the second slot 511b to the end face of the support section 511. The first engaging portion 512a is provided with the second engaging portion 512b at the end far from the hinge end of the opening and closing section 512. In the closed state, the second engaging portion 512b engages with the second slot 511b. In this way, the swing of the opening and closing section 512 can be further restricted in the closed state, so that the opening and closing section 512 can be stably maintained in the closed state.

[0077] In some embodiments, the rear end face 421 of the handle 42 is a convex arc surface, the generatrix of which extends along the length of the vertical tube 30, and the suspension part 51 is an arc shape that convexes away from the handle 42. This avoids sharp edges in the suspension part 51, ensuring safety during use, and also allows for a larger gap between the suspension part 51 and the rear end face 421 of the handle 42, facilitating the hanging of various types of items.

[0078] 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.
