Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to a steering and positioning structure for a handlebar of a dual-drive electric vehicle. Background Art

[0002] There are many technologies on the market that propose dual-drive electric vehicles with dual drive devices to solve the problem of insufficient power. For example, a dual-drive electric vehicle proposed in a public technology has a dual drive device on the vehicle body, which solves the problem of low horsepower of traditional electric vehicles.

[0003] The handlebar of a dual-drive electric vehicle is connected to the front shock absorber of the front wheel through a handlebar. When the handlebar and the front shock absorber locking nut are loosened after the dual-drive electric vehicle is driven for a long time or after the dual-drive electric vehicle falls, the handlebar and the front shock absorber will rotate relative to each other, causing the handlebar and the front wheel to be non-vertical. At this time, even if the handlebar is turned to a horizontal state, the front wheel of the dual-drive electric vehicle is in a tilted position, so that the vehicle will deviate. At this time, the handlebar needs to be adjusted manually. The traditional adjustment method is to completely loosen the nut, clamp the front wheel with both legs and then manually pull the handlebar. Not only is the operation cumbersome, but when the nut is completely loosened, the handlebar is very easy to rotate freely relative to the front shock absorber. Even after adjustment, when the nut is tightened with a wrench, the application of external force will cause the handlebar to deflect relative to the front shock absorber again. At present, there is only a structure for steering and positioning the handlebar of a motorcycle in the public technology. The front wheel clamp I and the front wheel clamp II clamp the front wheel, and the rear wheel clamp I and the rear wheel clamp II move relatively inward, so that two rollers clamp the left and right ends of the rear wheel tire. The operator loosens the nut between the handlebar and the front shock absorber, but does not rotate it too loosely. The rear wheel of the motorcycle rotates, and then the power wheel rotates. The linkage device drives the turntable to rotate clockwise to a certain angle and then automatically reverses and rotates counterclockwise. The front wheel of the motorcycle drives the front shock absorber to twist forward and then reverse. When the operator observes that the handlebar and the front wheel are adjusted, he squeezes the brake. After the power wheel stops rotating, the turntable stops rotating. At this time, the position of the handlebar is positioned and the front wheel remains fixed. At this time, the operator can use a wrench to tighten the nut. The entire operation process can be completed on the vehicle, which is convenient for use in motorcycle and electric vehicle repair shops, and improves the efficiency of adjusting the handlebars of motorcycles or electric vehicles and the convenience of operation.

[0004] The above-mentioned public technology can also be used for dual-drive electric vehicles, but its use is relatively cumbersome, and the positioning between the handlebars and the front wheels is still through manual observation with average accuracy. After the positioning is completed, the handlebars are still in a non-positioned state when the screws are tightened, and may still be displaced due to the tightening of the screws. Therefore, it is necessary to improve its structure. Utility Model Content

The two groups of clamping plates 16 can slide along the outer walls of the four groups of second sliding rods 15. By setting the four groups of second sliding rods 15, a good guiding effect is played, and at the same time, the rear end of the clamping plate 16 can be prevented from giving way when the front end is clamped;

[0028] The two groups of clamping plates 16 extend toward the front side of the first sliding structure, and the inner walls of the two groups of clamping plates 16 are provided with a clearance groove 17 that penetrates the front end. The left wall of the left group of the two groups of vertical plates 14 is fixedly connected with a rotating seat 18, and the inner wall of the rotating seat 18 is rotatably connected with a rotating rod 19. The end of the rotating rod 19 facing the vertical plate 14 sequentially penetrates the inner wall of the left group of the two groups of vertical plates 14, the inner wall of the two groups of clamping plates 16, and the inner wall of the right group of the two groups of vertical plates 14. The rotating rod 19 is threadedly connected to the two groups of clamping plates 16, and the end of the rotating rod 19 extending to the left side of the rotating seat 18 is fixedly connected with a hand wheel 2 0, the outer wall of the rotating rod 19 between the two sets of vertical plates 14 is arranged on the left and right sides in sequence with a first thread segment 21 and a second thread segment 22, the first thread segment 21 and the second thread segment 22 have opposite thread directions, and the two sets of clamping plates 16 are respectively threadedly connected with the first thread segment 21 and the second thread segment 22. The hand wheel 20 is rotated forward or reversely to drive the rotating rod 19 to rotate forward or reversely. Through the characteristics that the first thread segment 21 and the second thread segment 22 have opposite thread directions, the two sets of clamping plates 16 can be driven to move closer to or farther from each other, and the front wheel can be clamped when they are close to each other;

[0029] Two groups of columns 3 are fixedly connected in sequence on the upper wall of the bottom plate 1 and near the rear wall in a left-right distribution. The upper walls of the two groups of columns 3 are provided with a crossbeam 5 through a height adjustment structure. The front wall of the crossbeam 5 is slidably connected with a connecting plate 7 through a second sliding structure.
