When the swing rod 32 rotates relative to the fixed frame 31, the spring assembly 33 can swing in the space of the avoidance groove one 311 and the avoidance groove two 321 without interference. As shown in fig. 6 and 7, at this time, the spring assembly 33 is located on the right side of the fixing frame 31, and the stretching action of the spring assembly 33 makes the roller assembly vertically upwards and tightly contact with the side wall of the track; as shown in fig. 10 and 11, at this time, the spring assembly 33 is located at the left side of the fixing frame 31, and the roller assembly is in a horizontal state due to the stretching action of the spring assembly 33, so that the roller assembly can be closely attached to the ground surface. That is, when the swing rod 32 drives the roller assembly to move to the switching position, the spring assembly 33 can swing in the space of the avoidance groove one 311 and the avoidance groove two 321.

Further, the two sides of the bottom end of the fixing frame 31 are respectively provided with a limiting part 314, the limiting part 314 is provided with a limiting groove 3141, two side walls of the limiting groove 3141 are set to be at fixed angles, the round end of the upper end of the swing rod 32 is tightly clung to the round inner groove of the center of the limiting groove 3141 to be rotatably arranged, and the angles of the two side walls of the limiting groove 3141 are preferably set to be 90 degrees. When the swing rod 32 rotates by a fixed angle, the side wall of the swing rod 32 clings to the side wall of the limit groove 3141 to be limited.

As shown in fig. 6 and 7, when the swing rod 32 rotates anticlockwise until the side wall of the swing rod 32 is clung to the right side wall of the limit groove 3141, at this time, the swing rod 32 cannot continue to rotate anticlockwise again to reach the maximum rotation angle, and at this time, the roller assembly is just in a vertical state and can be clung to the side wall of the track.

As shown in fig. 10 and 11, when the swing link 32 rotates clockwise until the side wall of the swing link 32 is tightly attached to the left side wall of the limit groove 3141, the swing link 32 cannot continue to rotate clockwise again until the maximum rotation angle is reached, and the roller assembly is in a horizontal state and can be tightly attached to the ground surface. That is, the design of the limiting groove 3141 can enable the roller assembly to be limited after rotating to a fixed angle and a fixed position.

Referring to fig. 8 and 9, further, the bottom end of the fixing frame 31 is provided with a circular guide groove 3211 at the upper end of the swing rod 32, and the arc-shaped end of the fixing frame 31 is slidably disposed close to the guide groove 3211. That is, after the fixing frame 31 and the swing rod 32 are rotationally connected through the rotating shaft 315, the guiding groove 3211 is further designed to perform limit guiding, so that the connection stability of the fixing frame and the swing rod is further improved.

In the utility model, the driving component is preferably a motor 7, the motor 7 is fixedly clamped and fixed on the limiting part 314, and the motor 7 and the output shaft are connected with one of the rotating shafts 315 for transmission. The motor 7 directly drives the rotating shaft 315 to move so as to drive the swing rod 32 to rotate, and therefore the position of the roller assembly is adjusted.

Further, the bottom of pendulum rod 32 extends and is provided with U-shaped mount pad 36, articulates in the mount pad 36 has roller assembly, and roller assembly includes fixing base 35 and rotates the gyro wheel 34 that sets up on fixing base 35, and fixing base 35 passes through the axle 351 and is connected with mount pad 36, is provided with torsion spring on the axle 351, and torsion spring's the other end and the inner wall fixed connection of mount pad 36. As shown in fig. 6 and 10, in the initial state, the roller 34 is limited by the torsion spring, and the roller 34 and the mounting seat 36 are in a parallel state; once the support assembly is stressed, i.e., the roller 34 is subjected to a force, the roller 34 may deflect at an angle relative to the mounting seat 36, and the torsion spring is stretched, so that the roller 34 may return after the roller 34 is in force contact.

In this case, as shown in fig. 1, the roller 34 is pressed against the ground surface 6, and if the bicycle is in a running state, the roller 34 is blocked from being forced when the roller 34 encounters a foreign object such as a raised stone, a sleeper, or the like, so that it is deflected at an angle with respect to the mounting seat 36, thereby buffering the passage of the obstacle.

In this case, as shown in fig. 2, the roller 34 is tightly attached to the side wall of the track 5, and if the bicycle is in a running state, the roller 34 can be blocked from being stressed when the side wall of the track 5 is uneven, has foreign matters, and the like, so that the roller 34 deflects at a certain angle relative to the mounting seat 36, thereby buffering the passing obstacle.

As shown in fig. 4 and 5, the rail 5 is not a smooth rail, and fixing plates 4 are provided on both side walls and are connected and fixed by bolt assemblies 41 at the joint of two adjacent rails 5 to connect the two rails. Thus, when the vehicle is in this position, the roller 34 cannot pass against the side wall of the rail 5, because the roller 34 is blocked by the presence of the fixing plate 4 and the bolt assembly 41. In this case, the driving assembly drives the swing rod 32 to rotate, so that the roller 34 is changed from being closely attached to the side wall of the rail 5 to being closely attached to the ground surface 6, and the fixing plate 4 and the bolt assembly 41 are bypassed, so that the junction of the two rails 5 can be passed.

Preferably, at least one side of the roller 34 is provided with a tapered buffer 341.

When the roller 34 is provided with the buffer portion 341 on the side far away from the fixing seat 35, the roller 34 can be slowly clung to the side wall of the track 5 in the process of rotating from the close-to-ground base surface 6 to the close-to-track 5, and the resistance of the roller 34 is reduced.

When the roller 34 is provided with the buffer portion 341 on one side close to the fixing seat 35, the roller 34 can be slowly clung to the ground surface 6 in the process of rotating from the side wall clung to the track 5 to the clung to the ground surface 6, and the resistance of the roller 34 is reduced.

As shown in fig. 12, when the buffer portions 341 are provided on both sides of the roller 34, the resistance of the roller 34 can be reduced regardless of the direction in which the roller 34 moves. In particular, the roller 34 can be quickly separated from the ground surface 6 when the roller 34 rotates from the ground surface 6 to the side wall of the track 5, so that friction between the roller 34 and the ground surface 6 is reduced.

The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
