The charging assembly(4)is disposed between the first and second portions (201,202) and includes a circuit board,a chip (401) disposed on the circuit board and contacted with the first portion (201),a charging coil and an exciting unit.The connecting assembly (5) defines a first end electrically connected with the circuit board.A method for charging an apparatus with the wireless charging device (100) is also provided.
Abstract:
Embodiments of the present disclosure are drawn to a wave-absorbing material that includes a main composition, an auxiliary composition, and a sintering additive. The main composition includes at least one of Fe2O3, MnO, ZnO, and MgO. The auxiliary composition includes at least one of CeO2 and P2O5. The molar ratio of CeO2 to P2O5 ranges from about 1:1 to about 2:1. A method for preparing the wave-absorbing material is also provided.
Abstract:
The present invention disclosed a spring and a spring assembly formed by the spring. The spring which comprises a first end, a second end, and a spring main body connected between the first end and the second end, in which the spring main body comprises a compression spring portion and a torsion spring portion, and the spring main body is substantially located in a same plane. The spring according to the present invention comprises a compression spring portion and a torsion spring portion, so that a plurality of segments of the spring deforms during deformation of the spring, the stress is allocated among the plurality of segments and the spring life is increased. In addition, the spring thickness may be reduced, which is advantageous for thinning of the spring driving module and mobile terminal.
Abstract:
The present invention provides a sliding module comprising a plurality of guiding rods; a plurality of elastic members; a first component having a first fastener and a plurality of guiding apertures; and a second component having a second fastener and a plurality of fastening holes that correspond to the plurality of guiding apertures of the first component; wherein the first component and the second component are configured to slide with respect to each other; each of the elastic members is configured to shield a respective guiding rod; each of the guiding rods is configured to be fastened in a respective fastening hole at the second component, and traverse through a respective guiding aperture at the first component; and a longitudinal axis across the respective centers of the first fastener and the second fastener is configured to be parallel to each of the guiding rods.
