Abstract: A concealed charging device of an electrical vehicle, as well as a method thereof, is provided, including a base body arranged, in a concealed manner, in an electrical vehicle. The base body is provided with an extendible member. A driving member controls the extendible member for reciprocal movement in a longitudinal direction on the base body. The extendible member is also provided with an electricity-conducting assembly, which includes a conduction member and an electricity-conducting member. As such, to do charging, the driving member controls the extendible member to extend in the longitudinal direction and the electricity-conducting member is collaboratively operating with a charging seat to achieve electrical transmission of electricity through the electricity-conducting member and the conduction member for carrying out charging to a battery of the electrical vehicle. Further, the charging can be performed while traveling.

Abstract: An electrical connector structure includes an insulating body, ground terminals, and a grounding piece. The insulating body has a divider block. The ground terminals are fixed on the insulating body and arranged in two opposite sides of the divider block. Each ground terminal has a docking portion, a main portion, and a tail portion. The main portions are fixed on the insulating body. The docking portions and the tail portions extend from two sides of the insulation body. The grounding piece is fixed on the divider block. The grounding piece has a first mounting plane and a second mounting plane corresponding to the first mounting plane. The first mounting plane and the second mounting plane are located at two opposite surfaces of the divider block, and have contact portions protruding therefrom. The contact portions electrically contact the ground terminals respectively.

Abstract: The present invention discloses a golf club face assistance device. A proper location on a shaft of a club is provided with a first fixing element and is extended with a first assistance element. The other end of the first assistance element is connected with a second fixing element, and the first assistance element is provided with a second assistance element which is extended toward the shaft. An interface between the first and second assistance elements is defined with an aim point, and a virtual club face is defined from the aim point to the club face. By the virtual club face, one can easily learn a correct hitting form and a correct hit point.

Abstract: A 3D supporting stand for monitors uses a plastic metal tube to serve as a movable device, such that he plastic metal tube can perform rotation and movement in multiple angles, and is extended into the holding tube for connection. By means of a latching device inside the holding tube, the plastic metal tube can be adjusted with retraction, thereby increasing an agility of the monitor supporting stand, and enabling the entire structure to move to any angle and reach to a desired position, so as to achieve a variation of 3D multiple angles, and to facilitate increasing a comfort upon viewing in compliance with ergonomics. Moreover, when the plastic metal tube is completely retracted into the holding tube, the monitor can be adjusted to be horizontally or vertically embedded into an object attached by the holding tube for collection, thereby saving a space.
