Description

Steering handle adjusting mechanism for electric motorcycle Technical Field The invention relates to the technical field of motorcycle assembly, in particular to a steering handle adjusting mechanism for an electric motorcycle. Background The steering handle of the electric motorcycle is a core component for controlling the steering of the vehicle, and directly affects the riding stability, the control precision and the safety; for the steering handle of the electric motorcycle, the prior art still has some defects: 1. The flexibility is lacking, namely, once the steering handle is installed, the height is basically fixed, and if the original installation is not carried out, or the body condition and riding requirement of a rider are changed, the steering handle can be always in an uncomfortable posture, and the strain is easily caused; 2. The adaptation cost is high, a perfect height is found for a specific rider, handles with different lengths and angles can be needed to be replaced, or a front fork vertical tube is cut, so that the adjustment process is a one-time adjustment process, more specialized knowledge is needed, and the trial-and-error cost is high; 3. The commonality is poor, namely, the same vehicle is difficult to perfectly adapt to another rider with larger figure difference under the condition of not replacing parts; 4. the impact of the wheels is directly transmitted to a steering handle through a steering column, so that the impact is brought to the arms of a rider; In view of the above problems, the inventors have proposed a steering handle adjusting mechanism for an electric motorcycle for solving the above problems. Disclosure of Invention The invention aims to solve the problems of poor flexibility, high adaptation cost, poor commonality and poor impact resistance of an electric motorcycle steering handle, and provides a steering handle adjusting mechanism for an electric motorcycle. In order to solve the technical problems, the steering handle adjusting mechanism for the electric motorcycle comprises an outer sleeve and a steering handle, wherein an axial adjusting bracket is slidably arranged on the outer sleeve, an inner sleeve is fixedly arranged on the axial adjusting bracket, an input shaft is rotatably arranged in the inner sleeve, the steering handle is fixedly arranged at one end of the input shaft, an output shaft is arranged at the other end of the input shaft, and a driving mechanism is arranged between the outer sleeve and the axial adjusting bracket. Preferably, bearings are fixedly arranged at two ends of the inner sleeve, and the input shaft is fixedly connected with an inner ring of the bearings. Preferably, the input shaft and the output shaft are matched through two splines, and a sliding bushing is arranged between the two splines. Preferably, the driving mechanism comprises a motor, a gear and a toothed plate, wherein the motor is fixedly arranged outside the outer sleeve, the gear is fixedly arranged at the driving output end of the motor, the toothed plate is fixedly arranged at one end of the axial adjusting bracket, and the gear is in meshed connection with the toothed plate. Preferably, a locking mechanism is arranged between the outer sleeve and the inner sleeve, and locks the inner sleeve and the outer sleeve. Preferably, the locking mechanism comprises a worm, a worm wheel, a threaded rod, a threaded sleeve and a tight supporting seat, wherein the worm is rotationally arranged outside the outer sleeve, the threaded sleeve is rotationally arranged outside the outer sleeve, the worm is meshed with the worm wheel and is connected, the worm wheel is fixed at one end of the threaded rod, the threaded rod is in threaded connection with the threaded sleeve, and the tight supporting seat is fixed at one end of the threaded sleeve. Preferably, a rubber pad is fixedly arranged on one side of the abutting seat, and one side of the rubber pad is movably contacted with the outer wall of the inner sleeve. Compared with the prior art, the invention has the beneficial effects that: 1. According to the invention, through the action of the driving mechanism, the height of the steering handle can be finely adjusted according to the height, arm length, riding habit and physical state (such as fatigue and injury) of a rider, so that the most comfortable riding posture is found, the pressure of the wrist, the shoulder, the neck and the back is reduced, the device is particularly suitable for long-distance travel, commute or leisure riding, and meanwhile, the adaptation cost can be reduced; 2. According to the invention, the same electric motorcycle can be more conveniently used by riders (such as families) with different statures by arranging the direction handle with adjustable height, and the height can be simply adjusted; 3. According to the invention, the height-adjustable steering handle is arranged, so that the steering handle can be adjusted under different road conditio
