Abstract: A sensing-enabled automatically foldable scooter frame includes a support frame, a seat, an electric pushrod, a sensor, a controller, and an operating member. The electric pushrod is provided at the support frame to drive folding and unfolding of the support frame. The sensor is provided at a surface of the seat. The controller receives a signal from the sensor to control extension or retraction of the electric pushrod. The operating member is electrically connected to the controller. The operating member is disabled when the sensor detects existence of pressure, and the controller controls the electric pushrod in a retracted state, thereby ensuring the support frame in an unfolded state. The operating member is enabled when no pressure is detected, and the controller drives folding or unfolding of the support frame. The present invention can prevent a scooter frame from being folded accidentally, thereby protecting a user from being hurt.

Abstract: A buffer guiding structure for an extension tube comprises an inner tube, an outer tube, and a buffer member. The inner tube is slidably sleeved into the outer tube. The buffer member is provided at an end surface of one end of the inner tube. An edge of the buffer member engages with an outer edge of the inner tube and abuts against an inner wall of the outer tube, such that when the inner tube extends outwardly, the buffer member is scrolled downwards to reduce a friction force, and when the inner tube retracts inwardly, the buffer member remains slidably abutting against the inner wall of the outer tube, thereby realizing buffer function. The buffer guiding structure for an extension tube has a simple structure and good buffing performance, and can protect hands from being clamped.
