[0003] The folding bicycle has folding joints, and the folding parts connected with each other rotate with each other through the folding joints to be folded or unfolded, so that the folding bicycle is switched between the folded state and the unfolded state.
[0004] However, the conventional folding bicycle is easy to be scattered under the action of external force between the folding parts folded with each other after folding, which affects the folding effect. UTILITY MODEL CONTENTS

[0014] In one of the embodiments, the first attracting member comprises an attracting part and a flange connected with each other, and the flange is protruded from the attracting part and forms a limiting groove together with the attracting part.
[0015] The second attracting member is inserted into the limiting groove and attracts the attracting part, and the flange is arranged around the second attracting member to limit the relative sliding between the second attracting member and the attracting part.
[0016] In one of the embodiments, the flange is an annular shape with a notch, and the size of the notch is smaller than the size of the second attracting member located in the limiting groove, so as to limit the second attracting member from sliding out of the limiting groove.
[0017] In one of the embodiments, the flange is a closed annular shape.
[0018] In one of the embodiments, the attracting part is a disc shape, the second attracting member is a cylindrical shape, and the flange is an arc shape which can be arranged around the second attracting member.

[0037] Referring to Figures 1-3 In one embodiment, the folding vehicle 100 includes at least two folding portions 10, and each adjacent two folding portions 10 are connected by a folding joint 20, and the adjacent two folding portions 10 are folded or unfolded by rotating relative to each other through the folding joint 20. That is, the folding vehicle 100 can include two folding portions 10 or more than two folding portions 10, and each adjacent two folding portions 10 are connected by a folding joint 20, and the adjacent two folding portions 10 are folded or unfolded by rotating relative to each other through the folding joint 20. It can be seen that the number of folding joints 20 is less than the number of folding portions 10.
[0038] In some embodiments, the folding vehicle 100 includes two folding portions 10, and the two folding portions 10 are connected by a folding joint 20, and the two folding portions 10 of the folding vehicle 100 can be folded or unfolded relative to each other through the folding joint 20.
[0039] In other embodiments, the folding vehicle 100 includes three folding portions 10, and since each adjacent two folding portions 10 are connected by a folding joint 20, the three folding portions 10 are correspondingly connected by two folding joints 20, and the adjacent two folding portions 10 are folded or unfolded relative to each other through the corresponding folding joint 20.
[0040] It can be conceived that in other embodiments, the number of folding joints 20 varies according to the number of folding portions 10.
[0041] The folding vehicle 100 further includes a magnetic attraction assembly 30, and each adjacent two folding portions 10 that rotate relative to each other are correspondingly provided with a set of magnetic attraction assemblies 30. Each set of magnetic attraction assemblies 30 includes a first attraction member 31 and a second attraction member 32, and the first attraction member 31 and the second attraction member 32 are respectively provided on the corresponding two folding portions 10. When the two folding portions 10 are folded, the first attraction member 31 and the second attraction member 32 are attracted along the approaching direction of the two folding portions 10 that approach relative to each other, and the concave-convex cooperation of the first attraction member 31 and the second attraction member 32 limits the mutual sliding between the attraction surfaces of the first attraction member 31 and the second attraction member 32 to separate them.
[0042] It should be noted that the direction of the two folding portions 10 approaching each other is that when the two folding portions 10 are folded, the two folding portions 10 are close to each other or approach each other at the end away from the folding joint 20, and the direction of the two folding portions 10 approaching each other is the approaching direction. The meaning that the first suction member 31 and the second suction member 32 are limited from being separated by the relative sliding between the suction surfaces of the first suction member 31 and the second suction member 32 is that at least one of the first suction member 31 and the second suction member 32 is formed with a recess, and at least one of the first suction member 31 and the second suction member 32 is formed with a protrusion. When the first suction member 31 and the second suction member 32 are suctioned, the protrusion extends into the recess, and the protrusion and the recess cooperate to limit the relative sliding between the suction surfaces of the first suction member 31 and the second suction member 32, thereby limiting the first suction member 31 and the second suction member 32 from being separated due to the relative sliding.
[0043] Specifically, continuing to refer to Figure 1 , the folding vehicle 100 is a folding bicycle, and the folding bicycle includes two folding portions. The two folding portions 10 are respectively a front wheel folding portion 10 and a rear wheel folding portion 10. The front wheel folding portion includes a front fork assembly 11 and a front wheel 12, and the rear wheel folding portion includes a rear fork assembly 13 and a rear wheel 14. The first suction member 31 is arranged on one of the front fork assembly 11 and the rear fork assembly 13, and the second suction member 32 is arranged on the other of the front fork assembly 11 and the rear fork assembly 13. By arranging that the folding bicycle includes the front wheel folding portion 10 and the rear wheel folding portion 10, the structure of the folding bicycle is simplified, and the unfolding and folding of the folding bicycle can be achieved by only operating the two folding portions 10.
[0044] It can be understood that in other embodiments, the type of the folding vehicle 100 is not limited, such as a folding motorcycle and the like. Meanwhile, the number of the folding portions 10 included in the folding vehicle 100 is not limited, such as three folding portions 10.
[0045] The above arrangement is that when the two adjacent folding portions 10 are folded, the first suction member 31 and the second suction member 32 are suctioned, and under the action of the suction force of the first suction member 31 and the second suction member 32, the two folding portions 10 are not easy to unfold, so that the folding portions 10 are easy to remain in the folded state, and the folding effect is better. When the two folding portions 10 need to be unfolded, the first suction member 31 and the second suction member 32 only need to be pulled apart in the direction opposite to the approaching direction. Meanwhile, since the first suction member 31 and the second suction member 32 are matched in recess and protrusion when the two folding portions 10 are folded, the relative sliding between the suction surfaces of the first suction member 31 and the second suction member 32 is limited, so that the suction of the first suction member 31 and the second suction member 32 is more reliable, and the folding portions 10 can always remain in the folded state before the first suction member 31 and the second suction member 32 are pulled apart, and the folding effect is better.
[0046] In some embodiments, referring to Figure 2 and Figure 3 , the first attracting member 31 and the second attracting member 32 are arranged at the ends of the two folding portions 10 away from the folding joint 20. When the first attracting member 31 and the second attracting member 32 are arranged at the ends of the two folding portions 10 away from the folding joint 20, a larger force is required to unfold the two folding portions 10 when they are attracted to each other, and the folding effect is better.
[0047] Of course, in other embodiments, the first attracting member 31 and the second attracting member 32 can also be arranged at other positions of the folding portions 10, such as being arranged at the ends of the folding portions 10 close to the folding joint 20.
[0048] In some embodiments, the first attracting member 31 is a piece of iron, and the second attracting member 32 is a magnet. Since the magnet can attract the piece of iron, a better attracting effect can be ensured.
[0049] In other embodiments, the first attracting member 31 and the second attracting member 32 are respectively magnets with opposite polarities. Since magnets with opposite polarities can attract each other, a better attracting effect can also be ensured.
[0050] In some embodiments, referring to Figures 4-6 , the first attracting member 31 comprises an attracting portion 311 and a flange 312 connected to each other, the flange 312 is protrudingly arranged on the attracting portion 311, and the flange 312 and the attracting portion 311 jointly form a limiting recess 313. The second attracting member 32 extends into the limiting recess 313 and is attracted to the attracting portion 311, and the flange 312 is arranged around the second attracting member 32 to limit the relative sliding between the second attracting member 32 and the attracting portion 311.
[0051] With the above arrangement, when the two folding portions 10 are folded, the second attracting member 32 extends into the limiting recess 313 and is attracted to the attracting portion 311 as the bottom wall of the limiting recess 313, and the flange 312 is arranged around the second attracting member 32 to limit the sliding of the second attracting member 32 relative to the attracting portion 311, so that the second attracting member 32 and the first attracting member 31 always remain in the attracted state, avoiding separation when they slide relative to each other.
[0052] In some embodiments, the flange 312 is an annular ring with a gap 3121, the size of the gap 3121 is smaller than the size of the second attracting member 32 located in the limiting groove 313, limiting the second attracting member 32 from sliding out of the limiting groove 313. When the folding part 10 is subjected to external force and has a tendency to drive the relative movement of the second attracting member 32 and the first attracting member 31, because the size of the second attracting member 32 is smaller than the size of the gap 3121, the second attracting member 32 will not slide out of the limiting groove 313 from the position of the gap 3121, thereby ensuring the attracting effect of the first attracting member 31 and the second attracting member 32. At the same time, the gap 3121 can also play a role in weight reduction.
[0053] In other embodiments, the flange 312 is a closed annular ring. When the folding part 10 is subjected to external force and has a tendency to drive the relative movement of the second attracting member 32 and the first attracting member 31, because the flange 312 is a closed annular ring, the second attracting member 32 cannot slide out of the limiting groove 313 from any position of the flange 312, thereby ensuring the attracting effect of the first attracting member 31 and the second attracting member 32.
[0054] Further, the attracting part 311 is disc-shaped, the second attracting member 32 is cylindrical, and the flange 312 is an arc-shaped flange that can surround the second attracting member 32. In this way, the shapes of the first attracting member 31 and the second attracting member 32 are more regular, facilitating the processing and manufacturing of the first attracting member 31 and the second attracting member 32.
[0055] It is conceivable that, in addition to the above-mentioned way of achieving the concave-convex cooperation of the first attracting member 31 and the second attracting member 32 by the second attracting member 32 extending into the limiting groove 313 formed by the flange 312 and the attracting part 311, other ways can also be used to achieve the concave-convex cooperation of the first attracting member 31 and the second attracting member 32, which are not limited herein. For example, protrusions and pits are respectively provided on the first attracting member 31 and the second attracting member 32, the protrusions on the first attracting member 31 and the pits on the second attracting member 32 are concave-convex cooperated, and the protrusions on the second attracting member 32 and the pits on the first attracting member 31 are concave-convex cooperated, to achieve the concave-convex cooperation of the first attracting member 31 and the second attracting member 32.
[0056] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.
[0057] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
