Abstract: An interchangeable vehicle-mounted cup holder disclosed in the utility model, comprises a retaining base to be set on a vehicle-mounted cup tray and a cup holder magnetically attached with the retaining base, wherein a screw cap is configured at the top of the retaining base. The screw cap is attached with an outrigger block through a quadrilateral linkage mechanism and drives the outrigger block to move through the quadrilateral linkage mechanism, so that the outrigger block is set against the cup tray and the retaining base is fixed firmly on the cup tray. The retaining base can be used to hold different cup types by changing the cup holder. This device has a simple structure and can be used to hold different cup types by changing the cup holder, which solves the problem that conventional cup holders cannot be compatible with multiple cup types.

Abstract: The present disclosure is applicable to the technical field of metering and distributing of an adhesive dispensing machine, and provides a machine learning-based flexible intelligent adhesive dispensing method.

Abstract: The present disclosure discloses a horizontal-axis ocean current power generation device for an underwater vehicle. The power generation device is disposed in a groove of a rotary body of the underwater vehicle, and includes an undercarriage unit, a yawing unit, and a power generation unit. The undercarriage unit can realize elevation and descent of the entire power generation device, and the power generation unit is capable of realizing arbitrary rotation within 360° in a horizontal plane through the yawing unit. The power generation device can actively yaw based on change of an ocean current direction to perform an incident flowing function. The power generation unit respectively drives an outer shaft and an inner shaft to rotate through a front blade and a rear blade that rotate in opposite directions, so as to drive inner and outer rotors of a motor, thereby cutting magnetic induction to generate electric power.

Abstract: A telescopic mobile electronic device support, including a pedestal on which a housing is mounted, a telescopic movable rod and a telescopic sleeve arranged thereon. The telescopic sleeve and the telescopic movable rod are mounted in the housing. The telescopic sleeve is provided with ball screws. The telescopic movable rod is provided with limiting grooves. The ball screws abut the limiting grooves. The steel balls of the two ball screws are pressed to move inwards when the telescopic movable rod slides. When aligned with the limiting grooves on the telescopic movable rod, the steel balls will eject to support the limiting grooves and fix the position of the telescopic movable rod. The limiting grooves on the telescopic movable rod abut the steel balls for limiting, to adjust the distance of the telescopic movable rod.

Abstract: A new mobile electronic device fixation clamp has a shell body, a control mechanism, a first clamp arm, a second clamp arm and a resetting mechanism; the control mechanism has a control block and a pulling plate; the control block is arranged on the shell body moveably and rotatably; the pulling plate is connected with the control block; the first clamp arm and the second clamp arm are arranged on the shell body slidably and are connected with two sides of the control block, respectively; the resetting mechanism triggers the pulling plate to reset. During use, the control block is pulled to rotate, thereby driving the first clamp arm and the second clamp arm to slide, and accordingly changing a distance between the first clamp arm and the second clamp arm and thus holding and fixing the mobile electronic device therebetween.
