[0015] The present invention has the following beneficial effects:

[0016] 1. The folding scooter adopts a curling type storage and folding structure through the curling frame, which significantly reduces the overall size of the device. Compared with the folding structure of ordinary scooters, the folding structure of this device has an excellent volume advantage, making the overall size of the device smaller and the space occupancy rate smaller. In addition, the device is more convenient to take and operate, and the overall structure is easy to store and easy to carry. The overall structure of the device can adapt to the use of various spaces and people, making the device more adaptable.

[0017] 2. The foldable scooter is configured such that the locating pin is disengaged from the connecting frame, and the supporting shaft is unfolded and perpendicular to the supporting long board at a 90-degree angle to complete the supporting state. At this time, the supporting shaft is released from the clamping effect on the curling frame, and is elastically acted upon by the internal structure of the elastic unfolding component, so that the curling frame in the curled state is stretched out, and the supporting structure of the end connecting plate and the long connecting plate is used to complete the unfolded state. The unfolding is limited to 180 degrees, which is convenient for the user to stand on the upper end of the curling frame. In the combat state, the user applies a force downward, and the curling direction of the curling frame is inward, so that the downward pressure is opposite to the curling direction, thereby achieving the folding effect while also having a rigid support structure, so that the device will not affect the supporting effect of the device when it is flexibly unfolded, and the device has the function of automatically popping open, which greatly increases the convenience of use of the device, makes the operation of the device simpler, saves operation time, and significantly improves the convenience effect brought by the device.

[0018] 3. The folding scooter, through the cooperation of the limiting inclined surface and the angle groove, is equipped with an elastic damping support structure on the basis of the curling structure inside the curling frame. When the curling frame is affected by the vibration of the user himself or the ground and sinks downward, it is directly supported by the elastic damping rod. When the operator stands on the upper end of the curling frame, the incoming vibration is offset, thereby achieving the device's own shock absorption requirements. Although the curling effect and the damping shock absorption function of the device are an integrated structure, the two do not affect each other, so that the device can achieve a great buffering support effect when in use, increasing the flexibility of the device while also having a buffering effect.

[0031] The lower surface of the supporting long plate 21 and the interior of the supporting middle plate 22 and the supporting short plate 23 are all provided with a paving structure 5. The second roller 25 is used to be placed in the paving structure 5. Connecting components 3 are installed on both sides of the supporting long plate 21. The connecting components 3 are used to provide a rotational connection between the supporting long plate 21 and the supporting middle plate 22, and between the supporting middle plate 22 and the supporting short plate 23.

[0032] A supporting shaft sleeve 7 is installed on the outside of the supporting shaft rod 1, and a connecting frame 12 is provided on one side of the supporting shaft sleeve 7. One end of the connecting frame 12 is rotatably connected to one end of the supporting long plate 21, and a positioning frame 13 is provided on the upper surface of one end of the supporting long plate 21. A positioning hole 14 is provided inside the positioning frame 13, and the positioning frame 13 is annularly inserted into the interior of the connecting frame 12. A positioning pin 15 is inserted into the interior of the connecting frame 12. The positioning pin 15 is used to pass through the interior of the connecting frame 12 and the positioning hole 14, and the positioning pin 15 is used to locate the active angle between the supporting shaft rod 1 and the curling frame 2. The connecting component 3 includes a long coupling plate 31 and an end coupling plate 32. The long coupling plate 31 is used to connect the supporting long plate 21 and the supporting middle plate 22, and the end coupling plate 32 is used to connect the supporting middle plate 22 and the supporting short plate 23;

[0033] The length of the end coupling plate 32 is greater than the thickness of the tail end frame 24 and the supporting short plate 23. The end coupling plate 32 is used to provide support for the supporting middle plate 22 when it is folded.

[0034] When folding a conventional scooter, the handlebars and the body are usually folded in half to complete the folding operation of the body. However, the effect of this folding method is not significant enough, and the space occupancy rate saved by this method is not much different from the effect brought by the body before it is folded, making it difficult to achieve further space saving of the structure;

[0035] The tail frame 24 and the supporting short plate 23 are folded: the tail frame 24 is turned 180 degrees, and the tail frame 24 is turned 180 degrees. Figure 2 Figure 3 As shown, the lower surface of the tail frame 24 is made to fit with the lower surface of the supporting short plate 23, and after the two are fitted together, the second roller 25 extends into the paving structure 5;

[0036] The short support plate 23 and the middle support plate 22 folding action: At this time, the short support plate 23 is flipped 180 degrees so that the upper surface of the tail frame 24 is in contact with the lower surface of the middle support plate 22. The length of the end coupling plate 32 is greater than the sum of the thicknesses of the short support plate 23 and the tail frame 24. After the short support plate 23 and the tail frame 24 overlap, the middle support plate 22 can directly curl the two together and wrap them, and the second roller 25 is inserted into the flattening structure 5 inside the middle support plate 22.

[0037] Folding action of supporting long board 21 and supporting middle board 22: Figure 3As shown, in the same manner, the long support plate 21 is covered on the outside of the short support plate 23, and the long coupling plate 31 is supported to form traction on the middle support plate 22, thereby completing the folding structure of the entire curling frame 2. The folding structure is a curling structure. When folding and installing, it is only necessary to stack one layer on top of another and install the layers around each other to complete the folding operation of the entire curling frame 2. Moreover, after folding, the device occupies very little space and is also easy to carry.

[0038] The curling frame 2 adopts a curling type storage and folding structure, so that the overall size of the device is significantly reduced. Compared with the folding structure of an ordinary scooter, the folding structure of this device has an excellent volume advantage, making the overall size of the device smaller and the space occupancy rate smaller. The device is more convenient to take and operate, and the overall structure is easy to store and has the effect of being easy to carry. The overall structure of the device can adapt to the use of various spaces and people, making the device more adaptable. The elastic expansion component 4 is installed inside the supporting long board 21. , the elastic expansion component 4 includes an inner cavity 41, a movable push plate 42, a telescopic column 43, a spring 49 and a stretching rope 44. The inner cavity 41 is provided inside the supporting long plate 21, and the movable push plate 42 is installed inside the inner cavity 41. The telescopic column 43 is installed inside the spring 49. The spring 49 is symmetrically installed on one side of the movable push plate 42. The elastic expansion component 4 is installed inside the supporting long plate 21 and the supporting middle plate 22. The two movable push plates 42 are connected by a stretching rope 44. The spring 49 is used to provide elastic pushing power support between the supporting long plate 21 and the supporting middle plate 22;

[0039] A stretching rope 44 is installed on one side of the movable push plate 42. The stretching rope 44 is used to connect the two movable push plates 42. The thrust generated by the two movable push plates 42 acts on the stretching rope 44. The stretching rope 44 is made of non-elastic material and is transmitted between the supporting long plate 21 and the supporting middle plate 22 to form a tightening force.

[0040] Automatic pop-up: elastic expansion components 4 are installed between the supporting long plate 21 and the supporting middle plate 22, the supporting middle plate 22 and the supporting short plate 23, and the supporting short plate 23 and the tail frame 24 to provide elastic contraction function, and the thrust is provided by the spring 49. The telescopic column 43 is used to keep the spring 49 moving in a straight line and push the movable push plate 42. After pushing the movable push plate 42, the stretching rope 44 is pulled. The elastic support is driven by the two springs 49, and the thrust generated acts on the inside of the movable push plate 42. The stretching rope 44 is made of non-elastic material. When the two movable push plates 42 are pulled at the same time, the force is transmitted to the inside of the supporting long plate 21 and the supporting middle plate 22, and the force is limited to the end position of the supporting long plate 21 and the supporting middle plate 22 by pulling the stretching rope 44.

[0041] At the same time, the long coupling plate 31 is supported, which is similar to a fulcrum. The stretching rope 44 is similar to a lever. The two movable push plates 42 pull the stretching rope 44 at the same time, generating a lever action, which pulls the angle between the supporting long plate 21 and the supporting middle plate 22 to 180 degrees, providing dynamic support for the expansion of the supporting long plate 21 and the supporting middle plate 22. Similarly, the supporting long plate 21, the supporting middle plate 22, the supporting short plate 23 and the tail frame 24 have dynamic support for elastic expansion.

[0043] Example 2

[0044] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1-8 A tapered groove is provided between the supporting long plate 21 and the supporting middle plate 22. The tapered groove is an angle groove 16. The angle groove 16 has an angle of 10 degrees. An angle groove 16 is provided between the supporting middle plate 22 and the supporting short plate 23 and between the supporting short plate 23 and the tail end frame 24. The angle groove 16 is used to enable the curling frame 2 to have a reverse activity angle in the curling direction. Limiting inclined surfaces 17 are provided on both sides of the supporting long plate 21, the supporting middle plate 22 and the supporting short plate 23 and one end of the tail end frame 24. The limiting inclined surfaces 17 are used to increase the range of activity between the structures.

[0045] The elastic expansion component 4 also includes an elastic damping rod 45, a support plate 46, a stop block 47 and a positioning groove 48. An elastic damping rod 45 is provided at one end of the supporting long plate 21, and a support plate 46 is installed at one end of the elastic damping rod 45. A stop block 47 is installed at one end of the supporting middle plate 22. A positioning groove 48 is provided at one end of the stop block 47. The positioning groove 48 is used to position the support plate 46. The elastic expansion component 4 is used to provide tightening force between the supporting long plate 21, the supporting middle plate 22 and the supporting middle plate 22, the supporting short plate 23 and the supporting short plate 23, and the tail end frame 24, as well as an elastic effect.

[0046] according to Figure 4 、 Figure 6 As shown, after the long support plate 21 and the middle support plate 22 are flattened, the angle groove 16 can cause the space between the two to be concave downward, and the limiting inclined surface 17 ensures that the long coupling plate 31 or the end coupling plate 32 is not affected when the two are concave. The same structure is provided between the long support plate 21 and the middle support plate 22, the middle support plate 22 and the short support plate 23, and the short support plate 23 and the tail frame 24.

[0047] By cooperating with the limiting inclined surface 17 and the angle groove 16, the connection between the long support plate 21 and the middle support plate 22 is in a downward concave state after being unfolded, and the multiple structures between the long support plate 21, the middle support plate 22, the short support plate 23, and the tail end frame 24 are combined with each other to increase the degree of concave. When the user stands on the curling frame 2, it will automatically sink under the influence of gravity. At the same time, the elastic damping rod 45 provides an elastic damping effect, and the support plate 46 is pressed against the inside of the positioning groove 48 to provide a damping support effect between the two, and the entire concave state of the curling frame 2 is lifted up, so that when the curling frame 2 sinks due to gravity, the falling gravity directly acts on the elastic damping rod 45, ensuring that when the user stands on the upper end of the curling frame 2, it can play a shock-absorbing support effect;

[0048] Through the cooperation of the limiting inclined surface 17 and the angled groove 16, the device is provided with an elastic damping support structure on the basis of the curling structure inside the curling frame 2, so that when the curling frame 2 is affected by the vibration of the user himself or the ground and sinks downward, it is directly supported by the elastic damping rod 45, so that when the operator stands on the upper end of the curling frame 2, the incoming vibration is offset, thereby achieving the shock absorption requirement of the device itself. Although the curling effect and the damping shock absorption function of the device are an integrated structure, the two do not affect each other, so that the device can achieve a great buffering support effect when in use, increasing the flexibility of the device while also having a buffering effect.

[0049] Example 3

[0050] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figures 1-8 The paving structure 5 includes a slot 51, an inner slot 52, a side flap 53 and a positioning shaft 58. The inner slot 52 located in the supporting long plate 21 is symmetrically provided above the slot 51. The side flap 53 is symmetrically installed inside the slot 51. One end of the side flap 53 is installed with a positioning shaft 58. The positioning shaft 58 is used to support the side flap 53 to rotate and is installed inside the slot 51.

[0051] The inner groove 52 is symmetrically provided with a supporting side shaft 56 located in the supporting long plate 21. The inner groove 52 is also provided with an upper supporting plate 55. One end of the upper supporting plate 55 is used to be rotatably connected to the top of the side flap 53.

[0052] A supporting side shaft 56 is symmetrically mounted on the outer side of the upper support plate 55. A bearing 57 is mounted on the top of the supporting side shaft 56. The bearing 57 is used to slide on the supporting side shaft 56. The supporting side shaft 56 is used to support the upper support plate 55 to move in the inner groove 52. One end of the supporting side shaft 56 is provided with an angled angle, which is used to lift the upper support plate 55.

[0053] A connecting sleeve 8 is provided at the top of the supporting shaft 1, an inner slot 9 is provided inside the connecting sleeve 8, a handlebar 10 is installed above the connecting sleeve 8, the handlebar 10 is used to be inserted into the inner slot 9, and elastic pins 11 are symmetrically installed below the handlebar 10. Holes are symmetrically provided on the outer side of the connecting sleeve 8, and the elastic pins 11 are used to be inserted into the hole slots.

[0054] When the second roller 25 is inserted into the slot 51, it first contacts the abutment 54 and pushes it to both sides. At the same time, the ends of the side flaps 53 are rotatably connected to the upper support plate 55. At the same time, the two sides of the upper support plate 55 are slidably connected to the inside of the supporting side shaft 56. When the side flaps 53 are unfolded, they drive one end of the upper support plate 55 to retract into the inside of the inner groove 52 according to the trajectory of the supporting side shaft 56, thereby achieving the unfolding effect. This structure is to facilitate the second roller 25 to provide a support structure for the top of the slot 51 after it is disengaged from the slot 51, so that the top of the slot 51 forms a flat state, which is convenient for the user to stand.
