Detailed implementation mode

[0021] The following further describes the embodiments of the present utility model in detail with reference to the accompanying drawings. However, these embodiments do not limit the present utility model. Any similar structures and their similar changes using the present utility model shall be included in the protection scope of the present utility model.

[0022] A scooter includes a folding mechanism on the scooter. For the specific setting of the folding mechanism, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the scooter folding mechanism includes a disc-shaped pushing piece 1, a horizontal positioning piece 2, and a vertical positioning piece 3. The horizontal positioning piece 2 is fixed in the connecting head 4, and the vertical positioning piece 3 is installed in the connecting head 4. The horizontal positioning piece 2 is preferably two groups, symmetrically arranged on both sides of the vertical positioning piece 3 respectively. Corresponding central holes 111 and positioning holes 222 are provided on the pushing piece 1, the horizontal positioning piece 2, and the vertical positioning piece 3. The connecting head 4 is provided with avoidance spaces corresponding to the central holes 111 and the positioning holes 222. A pushing shaft 333 is inserted into the central holes 111 of the horizontal positioning piece 2 and the vertical positioning piece 3, and a positioning pin 444 that is movably inserted is provided in the positioning hole 222. The end of the positioning pin 444 is connected to the pushing piece 1. The positioning hole 222 on the pushing piece 1 is used to connect the positioning pin, or the end of the positioning pin can be set to be flat, and the end of the positioning pin 444 is clamped by the rear cover and the pushing piece to prevent it from shifting. To make the positioning of the folding structure more firm, multiple groups of positioning holes 222 are provided on the horizontal positioning piece 2 and the vertical positioning piece 3, and multiple groups of corresponding positioning pins 444 are provided. When fixing, the front end of the positioning pin 444 is sequentially inserted into the corresponding positioning holes 222 on the horizontal positioning piece 2, the vertical positioning piece 3, and the horizontal positioning piece 2. Guide spaces are respectively provided at both ends of the connecting head 4 along the axial direction of the pushing shaft 333. A rear cover 5 is provided in the guide space close to the pushing piece 1, and a pushing cover 6 is provided in the guide space far from the pushing piece 1. The pushing cover 6 and the rear cover 5 are connected by the pushing shaft 333, and the pushing cover and the rear cover move back and forth in the guide space respectively. For the structure of the pushing shaft 333, it can be obtained by helically connecting two pins. One end of the pushing shaft is inserted from one end of the pushing cover, and the other end of the pushing shaft is inserted from one end of the rear cover, and the overall structure is connected by threaded connection. The horizontal positioning piece 2 and the vertical positioning piece 3 are connected by a guiding bolt 7, and a guiding chute 8 with a 90° arc angle is provided on the vertical positioning piece 3 corresponding to the guiding bolt 7. Pushing the pushing cover 6 drives the rear cover 5 and the pushing piece 1 to move outwards, thereby driving the positioning pin 444 to withdraw from the positioning hole 222, and the vertical positioning piece 3 rotates around the pushing shaft 333 for folding, and the guiding bolt 7 moves along the guiding chute.

[0023] Such as Figure 4As shown in the figure, in order to enable the push shaft 333 to push the push piece, a push sleeve 555 is sleeved on the push shaft 333. The front end of the push sleeve 555 abuts against the inner wall of the push cover 6, and the end of the push sleeve 555 abuts against the push piece 1. The push shaft 333 pushes the push piece 1 to move outwards. A spring 9 is sleeved on the push shaft 333 near the side of the push cover 6. One side of the spring 9 abuts against the inner wall of the push cover 6, and the other side of the spring 9 abuts against the adjacent horizontal positioning piece 2.

[0024] A cross bar 10 is extended and provided at the rear end of the connector 4. A cross fixing bar 11 is extended and provided at the rear end of the horizontal positioning piece 2. The cross fixing bar 11 is fixed within the cross bar 10. A vertical fixing bar 12 is extended and provided at the rear end of the vertical positioning piece 3. The vertical fixing bar 12 is fixed within the vertical bar 13. A guiding arc is provided at the head of the vertical bar 13. The vertical bar 13 rotates and folds around the cross bar 10.

[0025] For the structures of the push shaft and the positioning pin, the connection parts connecting the rear cover, the push cover and the push piece are all as shown in the figure. It can be a flat sheet-like structure similar to the head of a bolt, or other connection methods that can play a pushing and pulling role.

[0026] As Figure 4 and Figure 5 As shown in the figure, during use, the push cover can be pushed to drive the push piece of the rear cover to move outwards by the push shaft. When the push piece moves outwards, it will drive the positioning pin to withdraw from the positioning hole. Furthermore, the vertical positioning piece can be rotated around the push shaft. During rotation, the guiding bolt moves along the guiding chute. When the folding is completed, in the reverse direction, the rear cover can be pushed to drive the front cover and the push shaft to return to their positions, and the positioning pin enters the positioning hole again to play a positioning role.

[0027] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
