Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to an anti-collision bicycle. Background Art

[0002] Bicycles are not only a convenient means of transportation, but also play an important role in promoting personal health, environmental protection and social welfare. At present, in order to improve the anti-collision function of bicycles during riding, anti-collision devices are generally installed on special parts of bicycles.

[0003] After investigation, the Chinese utility model patent with publication number CN219544982U discloses a bicycle frame with anti-collision performance. It includes a frame body and a protective mechanism arranged on the outer wall of the frame body, and the protective mechanism also includes a sliding component and a rotating component. By arranging the anti-collision block, when the bicycle is used in daily riding, the bicycle frame is often exposed to the outside. When it is hit or scratched, the frame is prone to bend or scratch, which reduces the service life of the frame. In order to improve the anti-collision performance of the frame, when the anti-collision block is impacted, the impact force on the anti-collision block will drive the sliding block to slide along the inner wall of the slide groove through the rotation connection of the rotating rod. At the same time, the sliding of the sliding block will squeeze the telescopic rod and the spring, which has a buffering effect on the impact force on the anti-collision block, so as to realize the control operation of improving the anti-collision performance of the bicycle frame in daily use. Although the device can play an anti-collision role, the anti-collision structure may scrape the rider's legs when it is in the open state, which in turn has a certain impact on the rider during riding. At the same time, the device can play an anti-collision role for the bicycle itself, but cannot reduce the recoil force on the rider when the bicycle hits an obstacle in front during driving.

Suitable; when an impact occurs, the movement of the spring 64 can help maintain the contact between the wheel 2 and the ground, and maintain a good grip even on uneven roads, which helps the rider to better control the direction and stability of the bicycle and avoid losing balance due to sudden impact; through the buffering of the spring 64, the impact force on the bicycle front fork, frame 1 and rider's body can be reduced, and the risk of damage caused by impact can be reduced, such as reducing vibration damage to the hands, shoulders and waist; when an emergency situation requires emergency braking, a slight movement of the handlebar 5 can alleviate the forward momentum caused by inertia and reduce the risk of the rider falling forward due to emergency braking; the shock-absorbing design reduces the wear of bicycle parts caused by hard impact, which helps to extend the service life of the bicycle in the long run, especially for key parts such as the front fork, handlebar 5 and frame 1.

[0030] During use, when the bicycle hits an obstacle in front, the bicycle transmits an inertial force to the rider to impact forward, and then the rider pushes the cross slider 62 to move forward along the inside of the cross slide groove 69 through the handlebar 5. During the movement of the cross slider 62, the spring 64 is squeezed to shrink and accumulate force. Then, the buffering effect of the spring 64 can absorb the energy from the impact of the obstacle in front, reducing the vibration directly transmitted to the rider, making the riding process smoother and more comfortable. At the same time, when an emergency situation requires emergency braking, a slight movement of the handlebar 5 can alleviate the forward impact caused by inertia and reduce the risk of the rider tipping forward due to emergency braking.

The shock-absorbing pad 68 can reduce the impact force of the cross slider 62 on the cross groove 69 when the spring 64 is reset, thereby increasing the service life of the handle 61.

[0033] Furthermore, the fixed sleeve on the handlebar 5 is provided with an anti-skid sleeve 51, which is made of rubber or synthetic rubber. The rubber material can provide a stable grip and maintain good friction even in sweaty hands or rainy days to prevent hands from sliding.

[0034] Furthermore, a plurality of protrusions 511 are processed on the anti-slip cover 51 , and the protrusions 511 can further increase the friction between the hand and the anti-slip cover 51 .

[0035] A baffle plate 7 fixedly connected to the vehicle frame 1 is provided on the top of the wheel 2 , and the baffle plate 7 can block objects rotating in the circumferential direction when the wheel 2 rotates axially.

[0036] Example 2

[0037] See attached Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, the bicycle also includes an adjustment mechanism arranged on the handlebar 61 for adjusting the tightness of the spring 64, the adjustment mechanism includes a threaded groove 65 opened on the front side of the outer wall of the guide rod 63, the outer sliding sleeve of the guide rod 63 is arranged on a cross plate 66 threadedly connected to the threaded groove 65, and the cross plate 66 is slidably sleeved inside the cross slide groove 69, and the front end of the handlebar 61 is rotatably provided with a knob 67 fixedly connected to the front end of the guide rod 63; through the threaded cooperation between the threaded groove 65 and the cross plate 66, the tightness of the spring 64 can be adjusted to prevent the spring 64 from loosening after long-term use, resulting in the loosening of the cross slider 62 inside the cross slide groove 69, causing the bicycle to become unstable during riding.
