When the second locking member 14 is located between the frame body 1 and the rear wheel seat 12, the second locking member 14 locks the rear wheel seat 12, and the rear wheel seat 12 is oriented relative to the frame body 1. When the second linkage mechanism 4 drives the second locking member 14 to move out of the rear wheel seat 12, the rear wheel seat 12 is unlocked, and the rear wheel seat 12 can rotate relative to the frame body 1.

[0047] See also Figure 3 and Figure 8 The release mechanism 5 includes a release linkage assembly 51 and a driving member 52. The driving member 52 is movably disposed on the rider 2.

Specifically, the release linkage assembly 51 includes an operating portion 511 and a release steel wire 512. The release steel wire 512 is connected between the operating portion 511 and the driving member 52. The operating portion 511 is operated to drive the release steel wire 512 to pull the driving member 52. In this embodiment, the operating part 511 includes an operating button 511a and a rotating member 511b. The operating button 511a is slidably disposed on the rider 2.

The operating slider slides to pull the release wire 512, so that the release wire 512 pulls the driving member 52, so that the driving member 52 drives the first linkage mechanism 3 or the second linkage mechanism 4 to move. It can be understood that in Fig.14 In the embodiment, operating sliders, unlocking wires 512 and driving members 52 are provided on both sides of the rider 2. However, the structure of the unlocking mechanism 5 is not limited thereto. For example, the unlocking mechanism 5 can directly use an operating member slidably disposed on the rider 2 to connect with the driving member 52, and the driving member 52 can be directly driven to slide by operating the operating member.

[0048] See also Figure 3 , Figure 4 and Fig. 9In one embodiment of the first linkage mechanism 3, the first linkage mechanism 3 includes a first connecting member 31 and a first pulling member 32. The first connecting member 31 is movably disposed on the frame body 1. The first pulling member 32 is connected between the first connecting member 31 and the first locking member 13. The first connecting member 31 is driven by the release mechanism 5 to move, so as to drive the first pulling member 32 and the first locking member 13, so that the first locking member 13 is withdrawn from the front wheel seat 11, thereby releasing the front wheel seat 11. In this embodiment, the first connecting member 31 is pivoted to the frame body 1. Specifically, the middle part of the first connecting member 31 is pivoted to the frame body 1, and the first pulling member 32 is fixedly connected to one end of the first connecting member 31. The driving member 52 of the release mechanism 5 can push the other end of the first connecting member 31 to rotate the first connecting member 31, thereby pulling the first pulling member 32, and then pulling the first locking member 13 through the first pulling member 32 to move out of the front wheel seat 11. The frame body 1 is provided with a first slot 15, and the first connecting member 31 is movably arranged in the first slot 15. Specifically, the first connecting member 31 is pivoted in the first slot 15, and a part of the structure of the first connecting member 31 protrudes out of the first slot 15 so as to facilitate the driving member 52 to push. At the same time, the side wall of the first slot 15 can also limit the rotation of the first connecting member 31. Further, the first linkage mechanism 3 also includes a first elastic member (not shown) for resetting the first connecting member 31, and the first elastic member is arranged between the first connecting member 31 and the frame body 1. When the first connecting member 31 rotates and pulls the first traction member 32, the first connecting member 31 overcomes the elastic resistance of the first elastic member; when the driving member 52 no longer pushes the first connecting member 31, the first connecting member 31 can rotate and reset under the action of the elastic restoring force of the first elastic member, thereby pulling the first traction member 32 and the first locking member 13 to reset. The first elastic member can adopt existing torsion springs, compression springs and other parts.

[0049] See also Figures 1 to 3 as well as Figure 5 , Figure 6 , Fig.10In one embodiment of the second linkage mechanism 4, the second linkage mechanism 4 includes a second connecting member 41 and a second pulling member 42. The second connecting member 41 is movably disposed on the frame body 1. The second pulling member 42 is connected between the second connecting member 41 and the second locking member 14. The second connecting member 41 is driven by the unlocking mechanism 5 to drive the second pulling member 42 and the second locking member 14, so that the second locking member 14 withdraws from the rear wheel seat 12, thereby unlocking the rear wheel seat 12. In this embodiment, the second connecting member 41 is slidably disposed on the frame body 1. The frame body 1 is provided with a second groove 16, and the second connecting member 41 is movably disposed in the second groove 16. Specifically, the second connecting member 41 is slidably disposed in the second groove 16, and a part of the structure of the second connecting member 41 protrudes out of the second groove 16 so as to dock with the driving member 52. The driving member 52 of the release mechanism 5 abuts against and pulls the second connecting member 41 to slide, so that the second connecting member 41 pulls the second pulling member 42, so that the second pulling member 42 pulls the second locking member 14 out of the rear wheel seat 12. Further, the second linkage mechanism 4 also includes a second elastic member 44 for resetting the second connecting member 41, and the second elastic member 44 is arranged between the second connecting member 41 and the frame body 1. When the second connecting member 41 slides and pulls the second pulling member 42, the second connecting member 41 overcomes the elastic resistance of the second elastic member 44; when the driving member 52 no longer abuts against and pulls the second connecting member 41, the second connecting member 41 can slide and reset under the elastic restoring force of the second elastic member 44, thereby driving the second pulling member 42 and the second locking member 14 to reset. The second elastic member 44 can adopt an existing compression spring, but is not limited thereto. In this embodiment, the second linkage mechanism 4 further includes a second pulley 43, the second pulley 43 is pivotally connected to the frame body 1, the middle portion of the second traction member 42 is wound around the second pulley 43, one end of the second traction member 42 is fixedly connected to the second connecting member 41, and the other end of the second traction member 42 is fixedly connected to the second locking member 14. However, this is not limited to the above. In another embodiment, Figure 7 As shown, the second linkage mechanism 4 may not be provided with the second pulley 43, and the second connecting member 41 is used to directly pull the second traction member 42 to move, so that the second connecting member 41 and the second traction member 42 have the same direction.

[0050] It is worth noting that in another embodiment of the first linkage mechanism 3, the first linkage mechanism 3 can be used in conjunction with the above-mentioned second linkage mechanism 4 (such as Figures 5 to 7The first link mechanism 3 has the same structure as shown in the figure. Specifically, the first connecting member 31 of the first linkage mechanism 3 is slidably arranged on the frame body 1, and the first slot 15 of the frame body 1 can be arranged for the first connecting member 31 to slide. The driving member 52 of the release mechanism 5 can slide by abutting and pulling the first connecting member 31, thereby pulling the first traction member 32, and then pulling the first locking member 13 through the first traction member 32 to move out of the front wheel seat 11. When the driving member 52 slides by pushing the first connecting member 31, the first connecting member 31 overcomes the elastic resistance of the first elastic member; when the driving member 52 no longer abuts and pulls the first connecting member 31, the first connecting member 31 can rotate and reset under the action of the elastic restoring force of the first elastic member, and also drives the first traction member 32 and the first locking member 13 to reset. In another embodiment of the first linkage mechanism 3, the first linkage mechanism 3 can also include a first pulley, the first pulley is pivotally connected to the frame body 1, and the middle part of the first traction member 32 is wound around the first pulley.

Specifically, the middle part of the second connecting member 41 is pivotally connected to the frame body 1, one end of the second connecting member 41 is connected to the second pulling member 42, and the second elastic member 44 is arranged between the second connecting member 41 and the frame body 1. The driving member 52 of the unlocking mechanism 5 pushes the other end of the second connecting member 41, so that the second connecting member 41 rotates, thereby pulling the second pulling member 42 and the second locking member 14, so that the second locking member 14 moves out of the rear wheel seat 12, thereby unlocking the rear wheel seat 12. In the process of the driving member 52 pushing the second connecting member 41 to rotate, the second connecting member 41 overcomes the elastic resistance of the second elastic member 44; when the driving member 52 no longer pushes the second connecting member 41, the second connecting member 41 can rotate and reset under the elastic restoring force of the second elastic member 44, thereby driving the second pulling member 42 and the second locking member 14 to reset.

[0053] When driver 2 turns to Fig.12 In the second position shown, the rider 2 drives the third traction member 61, so that the end of the third traction member 61 pulls the first locking member 13 out of the front wheel seat 11, and the middle of the third traction member 61 releases the second locking member 14, so that the second locking member 14 is reinserted into the rear wheel seat 12, so that the rear wheel seat 12 on the same side as the rider 2 is locked and oriented relative to the frame body 1, while the front wheel seat 11 on the side not on the same side as the rider 2 can rotate relative to the frame body 1. At this time, when the rear wheel seat 12 needs to rotate relative to the frame body 1, the release mechanism 5 can be operated to make the driving member 52 of the release mechanism 5 push the second rotating mechanism, so that the second connecting member 41 of the second rotating mechanism is actuated and drives the second traction member 42, so that the second traction member 42 drives the second locking member 14 out of the rear wheel seat 12, so that the rear wheel seat 12 can rotate relative to the frame body 1, so that both the front wheel seat 11 and the rear wheel seat 12 can rotate in all directions relative to the frame body 1.
