  • Publication number: 20230366250
    Abstract: A hollow hinge includes a first hollow component, a second hollow component and a plurality of support assemblies. The first hollow component has a first surface and a second surface opposite to the first surface, and a plurality of concave portions are disposed on the second surface. The second hollow component is disposed on the second surface of the first hollow component and a plurality of receiving portions corresponding to the concave portions are disposed on the second hollow component. The support assemblies are respectively contained in the receiving portions and continuously butt against the first hollow component through a force. The hollow hinge avoids friction between components and strengthens support, thereby prolonging durability and improving assembly and production yield rate.

  • Patent number: 10707569
    Abstract: A wireless transmission expansion device includes: an expansion unit having a bottom base portion, the bottom base portion having therein a receiving space, wherein each of two sides of the bottom base portion extends to form a positioning clamping arm, and the two positioning clamping arms define therebetween a clamping space; a wireless transmission device disposed in the receiving space; and at least one antenna module disposed at the positioning clamping arms and being in signal connection with the wireless transmission device. Therefore, the wireless transmission expansion device operates in conjunction with an existing video apparatus or portable camera not capable of 4G transmission or not having internal storage space required for 4G transmission, so as to instantly transmit a large amount of video information.
