DETAILED DESCRIPTION

[0031] Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments are only used to illustrate the present invention and are not used in limiting the scope of the present invention.In addition, should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.

[0032] See also Figures 1 to 4 , Example 1, the present invention provides a foldable electric scooter, comprising a steering assembly 1, a pedal assembly 4, a handle assembly 2 connected to the upper end of the steering assembly 1, a front wheel 51 connected to the lower end of the steering assembly 1, and a rear wheel 52 connected to the rear and lower part of the pedal assembly 4;

[0033] The foldable electric scooter further includes a connecting assembly, namely a first connecting member 31 and a second connecting member 61. One end of the first connecting member 31 is connected to the direction assembly 1, and the other end is axially connected to the second assembly 61, so that the first connecting member 31 can rotate relative to the second connecting member 61. The second connecting member 61 is connected to the front end of the pedal assembly 4.

[0034] The first connecting member 31 is provided with a protrusion 32, a first hole 33, and a first locking button 34 that moves within the first hole 33. The second connecting member 61 is provided with a second locking button 37. A safety handle (not shown in the drawings) is provided inside the first connecting member 31. The lower end of the safety handle is connected to the second locking button 37 (e.g., via a screw rod). When the safety handle is raised, the second locking button 37 moves upward to lock the protrusion 32. When the safety handle is lowered, the second locking button 37 moves downward to separate from the protrusion 32. At this time, the first connecting member 31 connected to the protrusion 32 can rotate.

[0035] The first locking button 34 is connected to the bottom of at least one movable rod 71. The number of movable rods 71 ​​can be one, two, three or even more. The more movable rods 71 ​​there are, the more stable the connection with the fulcrum rod 72 and the first locking button 34 is. In this embodiment 1, there are two movable rods, and the lower part of the movable rod 71 is fixedly connected to the fulcrum rod 72 (here, any position on the movable rod 71 except the top and bottom can be fixedly connected to the fulcrum rod 72 to form a lever effect. Compared with the existing technology, controlling the first locking button 34 is more labor-saving, more convenient and safer. However, the middle or lower part of the movable rod is fixedly connected to the fulcrum rod 72, which can further save labor, be more convenient and safer, and can better realize the control of the first locking button 34). The position of the fulcrum rod 72 can be adjusted on the first connecting rod 31 as needed, and the fulcrum rod 72 is rotatably connected to the first connecting member 31 (can be The movable rod 71 can be selectively plugged into the first connecting member 31, that is, plugged into a single layer of connecting plate of the first connecting member 31, or simultaneously plugged into the parallel double-layer connecting plates of the first connecting member 31). A hand grip 73 is provided on the top of the movable rod 71 (for the rider to grip and apply force to drive the movable rod 71 to rotate, ultimately achieving the purpose of controlling the engagement or disengagement of the first locking button 34 and the second connecting member 61); when the hand grip 73 approaches the first connecting member 31 (that is, when the hand grip 73 is lifted), the hand grip 73 drives the movable rod 71 to rotate with the fulcrum rod 72 as the fulcrum, and the movable rod 71 drives the first locking button 34 to approach the second connecting member 61. When the hand grip 73 moves away from the first connecting member 31 (that is, when the hand grip 73 is lowered), the hand grip 73 drives the movable rod 71 to rotate with the fulcrum rod 72 as the fulcrum, and the movable rod 71 drives the first locking button 34 away from the second connecting member 61.

[0036] The second connecting member 61 is further provided with a first opening 62, a second opening 63, and a second hole 64. The second locking button 37 moves in the second hole 64. The movable rod 71 drives the first locking button 34 to approach the second connecting member 61 and engage with the second connecting member 61. That is, when the foldable electric scooter is in the unfolded state, the first locking button 34 is aligned with the first opening 62. When the foldable electric scooter is in the folded state, the first locking button 34 is aligned with the second opening 63. The movable rod 71 drives the first locking button 34 away from the second connecting member 61 and releases the engagement between the first locking button 34 and the second connecting member 61.

[0037] The first connecting member 31 is a parallel double-layer structure (i.e., the first connecting member is composed of two parallel connecting plates of the same shape, forming a parallel double-layer structure). The two movable rods 71 ​​are parallel and the bottoms of the two movable rods 71 ​​are both connected to the first locking button 34. The lower portions of the two movable rods 71 ​​are fixedly connected to the fulcrum rod 72, and the tops of the two movable rods 71 ​​are both connected to the hand grip 73. The two movable rods 71 ​​can be arranged in parallel inside the parallel double-layer structure of the first connecting member 31. However, in this embodiment 1, the two movable rods 71 ​​are located outside the parallel double-layer structure of the first connecting member 31 and are respectively on both sides of the first connecting member 31. The first locking button 34 located inside the parallel double-layer structure of the first connecting member 31 is parallel to the fulcrum rod 72, and both ends of the fulcrum rod 72 located inside the parallel double-layer structure of the first connecting member 31 are inserted into the parallel double-layer structure of the first connecting member 31.

[0038] At this time, the movable rod 71 acts as a lever, and the distance between the hand grip 73 at the top of the movable rod 71 and the fulcrum rod 72 (i.e., the power arm) is greater than the distance between the first lock button 34 at the bottom of the movable rod 71 and the fulcrum rod 72 (i.e., the resistance arm). That is, the rider can drive the first lock button 34 to move in the opposite direction and with greater force by applying a small force on the hand grip 73, which can more easily, more labor-saving, more convenient and quicker control the first lock button 34 to achieve the purpose of engaging or disengaging the first lock button 34 and the second connecting member 61. Moreover, the movable rod 71 here is more durable and practical than the switch button, and can also avoid the risk of the foldable electric scooter accidentally overturning due to holding the foldable electric scooter with one hand for a long time.

[0039] A first spring 75 is provided outside the fulcrum rod 72, one end of the first spring 75 is fixed to the fulcrum rod 72, and the other end of the first spring 75 is fixed to the fixing block 74. The first spring 75 can be a coil spring.

[0040] When the hand grip 73 is close to the first connecting member 31 (i.e., the hand grip 73 is lowered), the first spring 75 is in a relaxed state; when the hand grip 73 is away from the first connecting member 31 (i.e., the hand grip 73 is lifted), the first spring 75 is in a rotationally tightened state, and the rebound force of the first spring 75 (i.e., the pre-tightening force) acts on the fulcrum rod 72, so that the fulcrum rod 72 is subjected to a force in the opposite direction of the movement direction of the hand grip 73 (i.e., this force causes the fulcrum rod 72 to return to its original position and drive the hand grip 73 close to the first connecting member 31, i.e., completing the action of lowering the hand grip 73). Assuming that the rider releases the hand grip 73 at this time, the hand grip 73 will automatically move back to a position close to the first connecting member 31 (i.e., the hand grip 73 is in a lowered state) with the help of the first spring 75. If the rider pushes the grip portion 73 back to its original position (i.e., close to the first connecting member 31), the first spring 75 will accelerate the speed at which the grip portion 73 returns to its original position, thereby avoiding the risk of the foldable electric scooter accidentally tipping over due to holding the foldable electric scooter with one hand for a long time.

[0041] At the same time, the first spring 75 can also help the hand grip 73 to maintain a state close to the first connecting member 31 (that is, the hand grip 73 is lowered), and the leverage of the movable rod can indirectly help the first lock button 34 and the second connecting member 61 to maintain an engaged state (that is, the preload force of the first spring 75 helps the fulcrum rod 72 to maintain the position of the hand grip 73 close to the first connecting member 31, indirectly avoiding the disengagement due to accidental movement of the first lock button 34), thereby avoiding accidental disengagement of the two and causing danger to the rider, thereby improving safety performance.

[0042] The first hole 33 is an arc-shaped hole for the movement of the first lock button 34, facilitating the arc-shaped movement of the first lock button 34 with the fulcrum rod as the center. The size of the arc-shaped hole matches the first lock button 34, ensuring the movement trajectory of the first lock button 34 while providing a certain degree of support and fixation for the first lock button 34, helping the first lock button 34 to accurately engage with the second connecting member 61 and improving the efficiency of the engagement. The hand grip 73 is a straight round rod, which improves the rider's grip comfort and makes it easier for the rider to apply tension to the hand grip 73. Both ends of the fulcrum rod 71 located outside the first connecting member 31 are equipped with limit blocks 76 to prevent the ends of the fulcrum rod 71 from falling off the first connecting member 31.

[0043] In this embodiment 1, the steering assembly 1 is used to control the direction, the handle assembly 2 is used to hold the direction and is placed above the steering assembly 1, the pedal assembly 4 is used to support the rider, the front wheel 51 is used for traveling and is placed below the steering assembly 1, the rear wheel 52 is used for traveling and is placed behind and below the pedal assembly 4, and the connecting member is used to connect the steering assembly 1 and the pedal assembly 4 and realize relative rotation and snap-fit ​​fixation between the steering assembly 1 and the pedal assembly 4.

[0044] See also Figure 5, Example 2, a folding electric scooter provided by the present invention, the difference between Example 2 and Example 1 is that: there is no fixing block 74 in Example 2, and a first spring 75 is provided on the outside of the fulcrum rod 72, one end of the first spring 75 is fixed on the fulcrum rod 72, and the other end of the first spring 75 is fixed on the first connecting member 31 near the other end of the first spring 75, so that the fixing block can be omitted, which saves materials and the internal space of the parallel double layers of the first connecting member 31, and can also achieve the purpose of the present invention.

[0045] See also Figure 6 , Example 3, a folding electric scooter provided by the present invention, the difference between Example 3 and Example 1 is that: a fixing block 74 is provided in the parallel double layer of the first connecting member 31, a first spring 75 is provided on the outside of the fulcrum rod 72, one end of the first spring 75 is fixed on the first lock button 34, and the other end of the first spring 75 is fixed on the fixing block (74). When the hand grip 73 is close to the first connecting member 31 (i.e., the hand grip 73 is lowered), the first spring 75 is in a relaxed state. When the hand grip 73 is away from the first connecting member 31 (i.e., the hand grip 73 is lifted), the first locking button 34 rotates under the action of the movable rod 71 and the fulcrum rod 72, and at the same time drives one end of the first spring 75 to rotate. The direction of one end of the first spring 75 changes to generate a pre-tightening force, which acts on the first locking button 34. Assuming that the rider releases the hand grip 73 at this time, the first locking button 34 will drive the movable rod 71 to rotate with the fulcrum rod 76 as the fulcrum (move toward the second connecting member 61) with the help of the pre-tightening force of the first spring 75, indirectly helping the hand grip 73 to automatically move back to a position close to the first connecting member 31 (at this time, the hand grip 73 is in a lowered state). If the rider pushes the grip 73 back to its original position (i.e., close to the first connecting member 31), the preload force of the first spring 75 will accelerate the speed at which the grip 73 returns to its original position, thereby avoiding the risk of the foldable electric scooter accidentally tipping over due to holding the foldable electric scooter with one hand for a long time.

[0046] See also Figure 7 Embodiment 4 of the present invention provides a foldable electric scooter. This embodiment 4 differs from Embodiment 2 in that: in this embodiment 4, there is no fixed block 74. Instead, a first spring 75 is provided on the outside of the fulcrum rod 72. One end of the first spring 75 is fixed to the first lock button 34, and the other end of the first spring 75 is fixed to the first connecting member 31 near the other end of the first spring 75. The operating principles and effects of the grip 73, movable rod 71, fulcrum rod 72, first spring 75, and first lock button 34 of this embodiment 4 are the same as those of Embodiment 3 and are not further described here.

[0047] See also Figures 8 to 10, Example 5, a foldable electric scooter provided by the present invention, the difference between Example 5 and Example 2 is that: the first connecting member 31 is a parallel double-layer, and there is a movable rod 71. The movable rod 71 is located inside the parallel double-layer of the first connecting member 31 and the bottom of the movable rod 71 is connected to the first locking button 34. The lower part of the movable rod 71 is fixedly connected to the fulcrum rod 72, and the top of the movable rod 71 is connected to the hand grip 73; the first locking button 34 located inside the parallel double-layer of the first connecting member 31 is parallel to the fulcrum rod 72, and both ends of the fulcrum rod 72 located inside the parallel double-layer of the first connecting member 31 are inserted into the parallel double-layer of the first connecting member 31. At this time, the top of the movable rod 71 is preferably connected to the middle part of the hand grip 73, the bottom of the movable rod 71 is preferably connected to the middle part of the first lock button 34, and the lower part of the movable rod 71 is preferably connected to the middle part of the fulcrum rod 72. At this time, through a movable rod 71 with the fulcrum rod 72 as the fulcrum, the first lock button 34 can be controlled more labor-saving and conveniently, thereby achieving the purpose of engaging or disengaging the first lock button 34 with the second connecting member 61.
