Abstract

Provided is a rear three-point backrest-type electric power-assisted recreational vehicle, which is a tricycle with two front guide wheels and a rear drive wheel. A driver's seat is provided with a backrest. The two front guide wheels are double-fork arm shockproof suspension units, each of which is composed of an upper A-shaped arm, a lower A-shaped arm and a serially-connected damper helical spring. One end of each of the upper and lower fork arms is respectively connected with knuckles on the wheels in an up-down manner, and the other end is connected with upper and lower beams of a vehicle body. The serially-connected damper helical spring serves as a column, wherein the upper end thereof is connected with the upper beam of the vehicle body and the lower end is connected with a lower swing arm. The rear wheel is an electric power-assisted drive wheel, and is connected with the vehicle body via a rear wheel frame and a rear wheel damper. The three wheels are all independent suspension units. The seat is a backrest-type seat, which is comfortable to use and can be moved and adjusted back and forth. The angle of the backrest can be adjusted according to the demand of a driver. Meanwhile, the rear wheel is equipped with a speed-changing cone pulley. In this way, during the driving, the speed can be adjusted in accordance with the road conditions and the demand of a driver, making the driving stable, safe, easy and comfortable.

Description

3 the electric boosted RV recreational vehicle of backrest type in back

Affiliated technical field: a kind of electric boosted tricycle.

Background technology; Present electric assisted bicycle, electric boosted tricycle is various in style, and form is similar; Just do a little variations at size, height; Body frame structure for automotive, the mode of riding do not have to change basically, and it is also uncomfortable to ride, back 3 electric boosted RV recreational vehicle of backrest type; Changed traditional vehicle shelf structure, layout and the mode of riding, it is safe, light, comfortable to ride.

Summary of the invention: back 3 electric boosted RV recreational vehicle of backrest type are three-wheel vehicles of a rear drive sprocket layout of a kind of two front jockey wheels, and motorist's seat has backrest; The adjustable angle joint of backrest; Two front jockey wheels adopt two yoke (two A type arm) shockproof suspensions, and the back is electric boosted drive wheel, and three wheels all adopt independent suspension; Driving safety, it is easily comfortable to ride.

3 the electric boosted RV recreational vehicle of backrest type in back is characterized in that two front jockey wheels, the three-wheel vehicle of a rear drive sprocket layout; Front jockey wheel adopts two yoke shockproof suspensions, and two yoke shockproof suspensions are made up of two A font arms and series connected bumper coil spring up and down, up and down two A font arm one ends respectively with wheel on steering swivel link to each other up and down; The other end is put the beams in place with vehicle body, fine strain of millet is connected down, and series connected bumper coil spring serves as pillar, puts the beams in place with vehicle body and be connected in its upper end; The lower end links to each other with following A font arm, and A font arm is responsible for absorbing the transverse force when turning to up and down, and the pillar bumper is responsible for supporting tare and control wheel bob; Two A font arms up and down of two yoke suspensions have leg-of-mutton rock-steady structure, and it can well suppress the inclination of car when turning, and stronger lateral rigidity provides good lateral support; The pedal sprocket wheel is also reach between two front jockey wheels; Seat is to have the backrest type seat of feeling comfortable, can move forward and backward adjusting, and the angle of backrest can be regulated according to motorist's requirement; Under the seat battery, electric cabinet; Rear drive sprocket adopts the brushless motor power-assisted to drive, and steering handle is controlled wheel flutter on the both sides of seat through connecting rod, steering track rod, and trailing wheel is through trailing wheel vehicle frame and rear wheel shock-absorbing device and body contact; Trailing wheel is equipped with the speed change cone pulley simultaneously, when riding, can carry out speed governing according to road conditions and motorist's requirement.

3 the electric boosted RV recreational vehicle of backrest type in back owing to adopt the layout of a rear drive sprocket of two front jockey wheels, have reduced the height of motorist's seat; So improved the stability when RV recreational vehicle is gone greatly, human engineering is more pressed close in the change of vehicle frame and seat, the angle of back of seat can be regulated according to motorist's requirement; Make the bicyclist more comfortable when taking, by the antagonistic force of backrest, buttocks, waist, back all can be participated in firmly when riding; So laborsaving in the process of riding, light and comfortable, two front jockey wheels are owing to adopted two yokes (two A type arm) to add the shockproof suspension that series connected bumper coil spring is formed, two front jockey wheel controls are more accurately stable; Let wheel can be good at close proximity to ground; The shockproof suspension of two front jockey wheels is independent separately, and the electric boosted drive wheel in back is through trailing wheel vehicle frame and rear wheel shock-absorbing device and body contact; The suspension of three wheels is independent separately, makes the car more stability and safety of going.
