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.

The folding seat support frame (8) includes a linkage rod (81) and a frame body, wherein a front end of the linkage rod (81) is connected with the front vehicle frame (110), a rear end of the linkage rod (81) is pivotally connected with the frame body, and the linkage rod (81) is able to swing as the front vehicle frame (110) is folded and thus drives the frame body to fold. The folding scooter frame (100) has the advantages of quick and convenient folding operations.

Abstract: A folding drive mechanism of a folding scooter is provided between a front frame (110) and a rear frame (120) of the folding scooter, and the front frame (110) and the rear frame (120) are pivoted. The folding drive mechanism (130) comprises a drive rod (1) and a pull rod (2), wherein the drive rod (1) is pivoted on the rear frame (120) via a middle shaft (120a), one end of the pull rod (2) is pivoted on the front frame (110), the other end of the pull rod (2) is connected to the drive rod (1) to drive the drive rod (1), enabling the drive rod (1) to swing to drive the pull rod (2) so that the front frame (110) is driven to rotate and fold relative to the rear frame (120). The folding scooter is fast to fold, and convenient.

Abstract: A folding scooter frame (100) includes a front frame (1), a rear frame (2), a linkage rod (3) and a seat support frame (4). The front frame (1) and the rear frame (2) are pivotally connected. A front end of the linkage rod (3) is connected with the front frame (1), and a rear end of the linkage rod (3) is pivotally connected with a slider (5). A support rod of the seat support frame (4) is pivotally connected with the slider (5), the slider (5) is slidably provided on the rear frame (2). The linkage rod (3) is able to swing as the front vehicle frame (1) is folded and thus drives the slider (5) to slide so as to make the slider (5) drive the seat support frame (4) to fold. The folding scooter frame (100) has the advantages of quick and convenient folding operations.

Abstract: The present invention relates to a trolley, and more particularly to a lifting trolley capable of raising and lowering goods. The lifting trolley includes a trolley frame, a drive mechanism, and a bearing mechanism. The bearing mechanism is vertically slidably connected to the trolley frame, and the drive mechanism is disposed on the trolley frame and drives the bearing mechanism to slide vertically. Compared with the prior art, the lifting trolley provided by the present invention saves time and effort, is accurate in positioning, and facilitates conveying of goods.

Abstract: A telescopic frame is disclosed, which is applicable to a foldable bicycle or foldable electric vehicle, and includes a front frame, a rear frame and a telescopic device. First guide rails are symmetrically disposed on two sides of the front frame, second guide rails are symmetrically disposed on two sides of the rear frame, and the first guide rails and the second guide rails are fitted together and slidably connected. The telescopic device is fixed on the rear frame, and an output end of the telescopic device is fixed on the front frame to drive the front frame to be unfolded or folded relative to the rear frame. The telescopic frame is simple in structure and capable of being automatically folded.

Abstract: A foldable frame includes first and second upper bars, first and second lower bars, and first and second pin joint pieces. The first and second pin joint pieces are respectively provided with first and second pin joint holes. The first and second lower bars are respectively fixed with the first and second pin joint pieces. The first pin joint piece is pin-jointed with the second pin joint piece through the first pin joint hole, and end surfaces of the first and second pin joint pieces respectively abut against end portions of the second and first lower bars. Two ends of the first upper bar are respectively pin-jointed with an upper end of a front wheel support and at the second pin joint hole of the second pin joint piece. Two ends of the second upper bar are respectively pin-jointed with a rear wheel support and at the second pin joint hole of the first pin joint piece.

Abstract: A foldable seat rack mountable between a body rack and a seat of a foldable motorized vehicle, includes main supporting rods, upper rods, lower rods, a seat base, hooks, and an elastic element. Main supporting rods are fixed on two sides of the body rack respectively. Upper rods are pivoted on upper ends of the main supporting rods respectively. Lower rods are pivoted on middle portions of main supporting rods and a rear end of seat base respectively. Hooks are fixed on the upper ends of the main supporting rods respectively. The foldable seat base has a middle shaft. Middle portions on two sides of the seat base are opened with slide slots. Two ends of the middle shaft pass through the slide slots freely and are hooked by hooks. An elastic element is placed between the front end of the seat base, and the middle shaft.
