Patent number: 11952044Abstract: An all-terrain vehicle is provided. The all-terrain vehicle includes a vehicle frame unit. A steering mechanism is rotatably mounted to a front side of the vehicle frame unit. Front wheels are rotatable mounted to a lower side of the steering mechanism as being arranged pairwise as a left-side one and a right-side one and are controllable by the steering mechanism. The all-terrain vehicle includes a vehicle cover unit covering a periphery of the vehicle frame unit. The vehicle cover unit includes a front vehicle cover section. An open receiving space is formed between a top side of the front wheels and the front vehicle cover section. An inertial sensor is arranged in the open receiving space. As such, mounting and servicing the inertial sensor can be carried out without removing the front vehicle cover section or other parts, and thus, mounting and servicing of the inertial sensor is made easy.Type: GrantFiled: June 11, 2021Date of Patent: April 9, 2024Assignee: KWANG YANG MOTOR CO., LTD.Inventors: Te-Feng Chen, Guei-Cheng Ye, Shih-Bin Chien

Patent number: 9333856Abstract: A device for controlling power to a vehicular differential speed controller is applied to control a differential speed controller inside a vehicle, and has an input voltage regulation circuit, a trigger circuit, a driving circuit and a relay. The input voltage regulation circuit converts an input voltage into an operating voltage and supplies the operating voltage to the trigger circuit. The trigger circuit generates a trigger signal after receiving a parking brake signal, such that the driving circuit activates the relay according to the trigger signal and supplies an output voltage to the differential speed controller. Accordingly, the present invention can automatically provide a sufficient power supply time to the differential speed controller to switch an operation state of a vehicle differential to a locked state when the vehicle power is switched off and the parking brake is activated.Type: GrantFiled: December 1, 2014Date of Patent: May 10, 2016Assignee: KWANG YANG MOTOR CO., LTD.Inventors: Wei-Jen Cheng, Shih-Chia Hsieh, Te-Feng Chen

Publication number: 20100210417Abstract: A handle-mounted parking brake device includes a parking brake lever movable between a first position, where a brake unit is disposed at a non-braking position for permitting rotation of a wheel axle of a vehicle, and a second position, where the brake unit is disposed at a braking position, and a cutoff switch having a mechanical switch body displaceable with movement of the parking brake lever between switch-on and switch-off positions, where a condenser discharge ignition is powered by and cut off from a DC power supply, respectively. Premature activation of a starter motor can be avoided to ensure cutoff of an engine when the vehicle is in a parking brake state so as to reliably prevent inadvertent operation to drive the vehicle.Type: ApplicationFiled: February 11, 2010Publication date: August 19, 2010Applicant: KWANG YANG MOTOR CO., LTD.Inventors: I-Chien Lin, Te-Feng Chen
