Abstract: A universal door hinge for a vehicle and a method of using the universal door hinge for the vehicle. The universal door hinge includes: a hinge assembly; an upper rotation assembly; and a lifting assembly. In particular, the hinge assembly includes a rotation plate including a first rotation pin hole formed therein and a hinge arm including a differently-shaped bolt hole formed therein. The upper rotation assembly includes a rotation pin capable of passing through the first rotation pin hole of the hinge assembly to rotatably couple the hinge assembly to the upper rotation assembly. The lifting assembly includes a differently-shaped bolt capable of passing through the differently-shaped bolt hole of the hinge arm to couple the lifting assembly to the hinge assembly.

Abstract: A hinge structure for a vehicle coach door can include a bracket configured to be fixed to a vehicle body, wherein a first end portion of the bracket is hingedly coupled to a connecting plate, and a second end portion of the bracket includes an arch-shaped guide arm, a driving assembly coupled to the connecting plate to be movable along the guide arm, an electric-powered assembly coupled to the driving assembly, and a hinge arm configured to be fixed to the door, wherein the hinge arm is coupled to the electric-powered assembly so as to be movable relative to the electric-powered assembly, wherein the hinge arm is configured to be move linearly relative to the electric-powered assembly during a first operation, and wherein the hinge arm is configured to pivot in an arch shape relative to the bracket during a second operation.

Abstract: An adjustable door hinge structure includes: a mounting bracket mounted on a vehicle body; a hinge arm including a first end portion fixed to a door and a second end portion rotatably connected to the mounting bracket; and a position-limiting assembly including a housing fixed to the mounting bracket and a shaft protruding from an inside of the housing, wherein the shaft is configured for being moved relative to the housing to change a length by which a first end portion of the shaft protrudes from an inside of the housing, thus changing the maximum rotation angle of the hinge arm relative to the mounting bracket. The adjustable door hinge structure may improve a passenger's boarding experience by adjusting the maximum door opening angle to make it convenient for the passenger to get on and/or off a vehicle or close a door after boarding the vehicle.

Abstract: Disclosed is a fingerstall oximeter comprising an upper housing (11), a middle housing (12), a lower housing (13) and a detection unit. The upper housing (11), the middle housing (12) and the lower housing (13) are connected in turn. The lower housing (13) is made of silica gel, and a finger accommodating chamber (14) for accommodating a finger to be measured is formed between the opposed surfaces of the lower housing (13) and the middle housing (12). The fingerstall oximeter has high measurement accuracy and small volume, and is easy to disassemble and carry.
