Detailed Description
The invention will be further described with reference to specific embodiments and the accompanying drawings.
As shown in fig. 1 to 7, a frame structure comprises a front frame 1 and a rear frame 2, wherein front wheels 3 are arranged at the bottom of the front frame 1, rear wheels 4 are arranged at the bottom of the rear frame 2, the front frame 1 and the rear frame 2 are connected through a connecting frame, the connecting frame comprises a first connecting rod 5, a second connecting rod 6, a third connecting rod 7 and a fourth connecting rod 8, one end of the first connecting rod 5 is hinged with the front frame 1, the other end of the first connecting rod 5 is hinged with one end of the third connecting rod 7, the other end of the third connecting rod 7 is hinged with the rear frame 2, one end of the second connecting rod 6 is hinged with the front frame 1, the other end of the second connecting rod 6 is hinged with one end of the fourth connecting rod 8, the other end of the fourth connecting rod 8 is hinged with the rear frame 2, the first connecting rod 5 is arranged side by side with the second connecting rod 6, the third connecting rod 7 is arranged side by side with the fourth connecting rod 8, a locking column 10 with a locking ring 9 is, the hinged parts of the third connecting rod 7 and the fourth connecting rod 8 and the rear frame 2 are correspondingly provided with locking columns 10, and the hinged parts of the first connecting rod 5 and the third connecting rod 6 and the hinged parts of the second connecting rod 7 and the fourth connecting rod 8 are detachably connected through locking devices. The locking device may employ a locking post 10 with a locking ring 9.
The rear wheel 4 is arranged on a rear wheel frame 11, the top of the rear wheel frame 11 is rotationally connected with a rear frame 2, an upper support plate 12 extends outwards from the tail of the rear frame 2, a lower support plate 13 is correspondingly arranged on the rear wheel frame 11, the upper and lower support plates 12 and 13 are connected through a telescopic rod 14, and a spring 15 is sleeved outside the telescopic rod 14. When the bicycle runs on uneven ground, the rear wheel 4 drives the rear wheel frame 11 to rotate upwards, the spring 15 is compressed, and energy is absorbed; after the bicycle passes through the rugged bottom surface, the spring 15 recovers the natural state, the spring 15 pushes the lower support plate 13 downwards to release energy, the power is provided for the rotation of the rear wheel 4, and a certain labor-saving effect is achieved.
