Description

Technical Field

[0001] The utility model relates to a handlebar folding and locking device and a scooter, belonging to the technical field of scooters. Background Art

[0002] A scooter is a small vehicle, typically consisting of two or more wheels, that is propelled forward by the user pedaling. Scooters can be categorized into several types, including non-electric scooters and electric scooters.

[0003] Non-electric scooters typically consist of a flat pedal, one or two front wheels, and one or two rear wheels, and rely on human power for propulsion. Electric scooters, on the other hand, are based on non-electric scooters but incorporate batteries and motors, enabling autonomous propulsion. They are suitable for short trips and recreational activities. Furthermore, there are mobility scooters designed specifically for people with limited mobility. These scooters are often equipped with automatic braking and speed limiters to ensure user safety.

[0004] The use of scooters is not limited to personal transportation, but is also widely used in various sports and entertainment activities. For example, electric scooters have become the preferred tool for short-distance travel in many cities due to their environmental friendliness and convenience. In the field of extreme sports, professional scooters provide higher performance and controllability, and are suitable for performing various difficult skills. Existing scooters usually need to consider the function of folding and carrying. The front structure commonly used in the industry uses a snap-on method to achieve a foldable connection between the upright pole and the front steering part. Users usually stand on the scooter body and hold the front handlebar to drive the scooter. Since the upright pole of the scooter has a long force arm, the stress of the upright pole when accelerating, decelerating or moving during driving is concentrated at the snap-on connection position, which is easy to disengage or break, causing the upright pole to suddenly fold during driving, creating a safety risk. Therefore, there is an urgent need for a handlebar folding locking device with a folding safety structure. Utility Model Content
