Therefore, when the right lever 19 (or the left lever 18) is driven by the corresponding swing arm 1 and moves, the movement range of the corresponding movement of the middle lever 20 can be reduced through the lever structure of the transverse balance lever 17 (i.e. in this embodiment 1, the top of the middle lever 20 is connected with the middle point of the transverse balance lever 17, the movement range of the top of the middle lever 20 is half of the movement range of the top of the right lever 19, whereas after the right lever is replaced by the left lever 18, the movement range of the top of the middle lever 20 is half of the movement range of the top of the left lever 18), so that the pedal of the rear two-wheeled scooter caused by the obstacle of the wheels can be further reduced (the pedal is not embodied in the drawing, the pedal is parallel to the upper damper connecting rod 7 and the swing arm connecting rod 14, and the center line of the pedal is in the same vertical plane with the center line of the upper damper connecting rod 7 and the center line of the swing arm connecting rod 14, and the pedal inclination of the pedal has the same direction and same range of the swing arm connecting rod 14, so that the stability of the rear two-wheeled scooter is enhanced, and the safety of the rider in the running process is improved.
When the right wheel encounters an obstacle (namely, a road surface bump which affects the stable running of the rear two-wheel pulley car), the swing arm 1 on the right side of the rear frame is driven to rotate towards the rear upper side of the rear two-wheel pulley car by taking the joint of the swing arm 1 and the swing arm connecting rod 14 as a fulcrum, at this time, the swing arm 1 also drives the bottom of the right side lever 19 to rotate towards the rear upper side of the rear two-wheel scooter by the lower balance mechanism connecting rod 16 on the right side of the rear frame 4, so that the whole of the right side lever 19 moves, the top of the right side lever 19 correspondingly moves towards the rear upper side of the rear two-wheel scooter at the same time (at this time, the amplitude of the movement of the top of the right side lever 19 is smaller than the amplitude of the movement of the bottom of the right side lever 19 because of a certain length of the right side lever 19), the top of the right side lever 19 drives the rear upper side of the transverse balance lever 17 again by taking the joint of the transverse balance lever 17 and the middle lever 20 as a fulcrum, and simultaneously the left end of the transverse balance lever 17 drives the top of the left side lever 18 to move towards the rear upper side in the opposite direction (the front lower side of the rear two-wheel scooter at this time), and the left side lever 17 moves towards the front lower side of the left side lever 18 together, namely, the left side lever 18 moves towards the left side of the left side lever 18 and the left side lever has a certain force of the left side lever 16, and the left side of the front two-wheel scooter, and the left side balance lever has a certain force of the left side and the left side roller and the front side roller. In the foregoing process, the transverse balance bar 17 drives the middle bar 20 to move upwards (or upwards and backwards), the bottom of the middle bar 20 drives the damping mechanism (i.e. the telescopic bar 9) to rotate upwards (or upwards and backwards) by taking the joint of the damping mechanism and the upper damping mechanism connecting bar 7 as a fulcrum through the lower damping mechanism connecting bar 13, and the damping mechanism plays a damping function (see later description for details), so as to further reduce the up-and-down vibration and/or the left-right tilting of the upper damping mechanism connecting bar 7 and the rear two-wheeled scooter pedal. When the right wheel leaves the obstacle, the right wheel (simultaneously the right side rod 19 and the transverse balance rod 17) is restored to the initial position (namely, the transverse balance rod 17 is in a horizontal state, the right side rod 19 is in a vertical state, and the left wheel and the right wheel are on the same horizontal ground) with the help of the shock absorption mechanism, and the rear two-wheel scooter pedal does not incline.
When a left wheel encounters an obstacle, the left swing arm 1 of the rear frame is driven to rotate towards the rear upper part of the rear double-wheel scooter by taking the joint of the swing arm 1 and the swing arm connecting rod 14 as a fulcrum, at this moment, the swing arm 1 also drives the bottom of the left side lever 18 to rotate towards the rear upper part of the rear double-wheel scooter by the lower balance mechanism connecting rod 16 on the left side of the rear frame 4, so that the whole left side lever 18 moves, the top of the left side lever 18 correspondingly moves towards the rear upper part of the rear double-wheel scooter (at this moment, the moving amplitude of the top of the left side lever 18 is smaller than the moving amplitude of the bottom of the left side lever 18 because of a certain length of the left side lever 18), the top of the left side lever 18 drives the left end of the transverse balance lever 17 to move towards the rear upper part of the rear double-wheel scooter by taking the joint of the transverse balance lever 17 and the middle lever 20 as a fulcrum, and simultaneously the right end of the transverse balance lever 17 drives the top of the right side lever 19 to move towards the opposite direction (the front lower part of the rear double-wheel scooter), and at this moment, the top of the right side lever 19 correspondingly moves towards the rear upper part of the rear double-wheel scooter, and the left side lever 19 simultaneously generates a certain force towards the rear lower side lever 16, namely the front double-wheel scooter has a certain lifting force towards the rear lower side of the rear double-wheel scooter. In the process, the transverse balance rod 17 drives the middle rod 20 to move upwards (or upwards backwards) at the same time, the bottom of the middle rod 20 drives the damping mechanism to rotate upwards (or upwards backwards) by taking the joint of the damping mechanism and the upper damping mechanism connecting rod 7 as a fulcrum through the lower damping mechanism connecting rod 13, and the damping mechanism plays a damping function to further reduce the up-and-down vibration and/or the left-right tilting of the upper damping mechanism connecting rod 7 and the pedal of the rear two-wheel scooter. When the left wheel leaves the obstacle, the left wheel (simultaneously the left side rod 18 and the transverse balance rod 17) is restored to the initial position (namely, the transverse balance rod 17 is in a horizontal state, the left side rod 18 is in a vertical state, and the left wheel and the right wheel are on the same horizontal ground) with the help of the damping mechanism, and the rear two-wheel scooter pedal does not incline.
When the left and right wheels simultaneously encounter an obstacle (the obstacle can be of the same height or different heights), the two processes simultaneously occur, the two wheels simultaneously drive the left side rod 18 and the right side rod 19 to move upwards and backwards (the distances of the upwards and backwards moving can be the same or different), the left side rod 18 and the right side rod 19 drive the middle rod 20 to correspondingly move upwards and backwards through the transverse balance rod 17, the middle rod 20 drives the bottom of the telescopic rod 9 to move upwards (namely the telescopic rod 9 is compressed), the corresponding limit flange 10 on the telescopic rod 9 compresses the spring 11, the vibration amplitude of the upper vibration-reducing mechanism connecting rod 7 brought by the two wheels is reduced by the spring 11, the purpose of reducing the vibration amplitude of the pedal is achieved, and the vibration-reducing mechanism plays a role in vibration reduction.
In the driving process of the rear two-wheel scooter, when the pedals are required to tilt (for example, the pedals need to turn in the driving process, especially fast turning, a rider can tilt towards one side of the pedals under the influence of centripetal force, and the pedals are required to tilt in the same direction and at corresponding angles, so that the rider can keep balance, the pedals are prevented from being overturned, personal safety of the rider is ensured), the balance mechanism can help the pedals to tilt more conveniently, safely and more effort-effectively (namely, the tilting angle is adjusted), namely, the rider can apply pressure on the pedals by utilizing self gravity, especially, the pressure on the left side and the right side of the pedals, the pressure effect is amplified to two wheels through the leverage of the balance mechanism, so that the two wheels are more convenient and rapid to change the height and the tilting angle of the corresponding swing arms, the tilting angle of the pedals is adjusted, namely, the rider can easily adjust the height and the tilting angle of the two wheels and the corresponding swing arms only by using a small pressure, the tilting direction and the angle of the pedals are adjusted, the pedal can achieve the purposes of saving effort by utilizing the leverage, and the requirements of the pedal for adjusting the pedal to be more convenient and the tilting angle by the rider with light dead weight, and the following specific operation.
When the rider needs to turn right in front of the scooter, the rider is affected by centripetal force to tilt right, the center of gravity of the rider is inclined right, the pressure of the rider on the right side of the pedal is increased, the pressure on the left side of the pedal is reduced (even left foot is separated from the left side of the pedal), the right side pressure of the pedal is increased, the swing arm 1 on the right side of the rear frame 4 rotates to the rear upper side of the rear double-wheel scooter by taking the joint of the swing arm 1 and the swing arm connecting rod 14 as a fulcrum, the swing arm 1 drives the right side rod 19 to move correspondingly to the rear upper side, the top of the right side rod 19 drives the left side rod 18 to move correspondingly to the front lower side (namely, the top of the right side rod 19 and the top of the left side rod 18 move in the same magnitude and in opposite directions), the left side rod 18 has a downward component force to the lower balance mechanism connecting rod 16 and the left wheel after decomposition, the downward component force can help the left wheel to support on the ground when the pedal is inclined, the pedal is ensured to always to be inclined, the two wheels can support the rear double-wheel scooter stably and the two-wheel scooter can not ride stably in the same direction, and the riding comfort of the scooter can be ensured, and the riding comfort of the riding of the scooter is improved.
