Description
Technical Field
[0001] The present invention relates to the technical field of balancing vehicles, and in particular to a unicycle balancing vehicle with an adjustable handlebar tension structure. Background Art
[0002] A self-balancing scooter is an electric vehicle that automatically maintains balance using a built-in gyroscope and sensors. Existing self-balancing scooters include two-wheeled scooters and one-wheeled scooters. Two-wheeled scooters have two wheels and pedals, offering high stability and are suitable for beginners and short commutes. One-wheeled scooters are for advanced enthusiasts, requiring a higher level of balance and are often used for acrobatics or urban commuting.
[0003] With the continuous development of balance scooters, in order to improve the portability of balance scooters, a shipping handle is generally installed on the balance scooter. In order not to occupy the volume of the balance scooter, a flip-up and storable shipping handle structure is adopted. One end of the shipping handle is hinged to the main body of the balance scooter. When the handle is not in use, it is flipped and stored, and when it is needed, it is flipped and used again. However, with long-term use, the plastic shipping handle is prone to loosening or deformation at the hinge, resulting in an unstable connection between the handle and the balance scooter. In order to solve the unstable connection, the existing solution can only be to return the handle to the factory for repair or replace the handle.

The outer peripheries of the adjustment head 221 and the connecting tail 222 are both provided with a tight-fitting inclined surface 223. The tight-fitting inclined surface 223 of the adjustment head 221 can cooperate with the inner wall of the adjustment channel 211 to achieve a tight fit between the adjustment head 221, the adjustment end and the hinge seat 11. The tight-fitting inclined surface 223 of the connecting tail 222 can cooperate with the inner wall of the connecting channel 212 to achieve a tight fit between the connecting tail 222, the connecting end and the hinge seat 11. A tightening screw 23 is threadedly connected to the adjustment head 221. A tightening boss 213 that cooperates with the tightening screw 23 is provided in the connecting channel 212. The tightening screw 23 can cooperate with the tightening boss 213 to move the connecting shaft 22 toward the adjustment channel 211.
[0028] By adjusting the tight-fitting bevels 223 on the head 221 and the connecting tail 222, when the connection between the consignment handle 2 and the hinged seat 11 becomes loose, the user adjusts the tightening screw 23 to move the connecting shaft 22 toward the adjustment channel 211, and the tight-fitting bevel 223 gradually fits tightly with the inner walls of the adjustment channel 211 and the connecting channel 212. At the same time, the connecting end and the adjusting end gradually fit with the hinged seat 11, and the tightness of the handle can be quickly adjusted, which effectively improves the flexibility of the consignment handle 2 and meets the user's usage needs.
[0029] When tightening is required, a tool is inserted into the adjustment channel 211 to rotate the tightening screw 23 clockwise. Under the action of the tightening boss 213, the position of the tightening screw 23 in the adjustment channel 211 remains unchanged, and the connecting shaft 22 gradually approaches the screw head of the tightening screw 23 to achieve tightening.
[0030] The cross-section of the adjusting head 221 is polygonal, and the front guide portion is an adjusting contour surface provided in the adjusting channel 211 and matching the shape of the adjusting head 221 .
[0031] The provision of the front guide portion can prevent the connecting shaft 22 and the handle ring 21 from rotating relative to each other, thereby preventing the user from experiencing the same.
[0032] A rear guide portion cooperating with the connecting tail 222 is provided in the connecting channel 212 . The cross-section of the connecting tail 222 is polygonal. The rear guide portion is a connecting contour surface provided in the connecting channel 212 and cooperating with the connecting tail 222 .

With long-term use, the consignment handle 2 made of plastic is prone to loosening or deformation at the hinge, resulting in an unstable connection between the handle and the balance car, and there are problems of high subsequent maintenance costs and low efficiency. By adjusting the tight-fitting bevel 223 on the adjusting head 221 and the connecting tail 222, when the connection between the consignment handle 2 and the hinge seat 11 becomes loose, the user adjusts the tightening screw 23 to move the connecting shaft 22 toward the adjustment channel 211, and the tight-fitting bevel 223 gradually fits tightly with the inner walls of the adjustment channel 211 and the connecting channel 212. At the same time, the connecting end and the adjusting end gradually fit with the hinge seat 11, and the tightness of the handle can be quickly adjusted, which effectively improves the flexibility of the consignment handle 2 and meets the user's usage needs.
