20130088193 | WIRELESS CHARGER WITH POSITION-GUIDING MECHANISM - A wireless charger includes a wireless charging body, a carrier and an elastic element. The wireless charging body has a track. The carrier includes an extension part, which is movably disposed on the track. The elastic element is connected with the carrier for providing a pulling force to the carrier, so that the carrier is maintained at an initial position. When an electronic device is held by the carrier, the carrier is moved from the initial position to a charging position along the track in response to a gravity force of the electronic device, so that a receiver coil of the electronic device is aligned with a transmitter coil of the wireless charging body. When the electronic device is not held by the carrier, the carrier is returned to the initial position in response to the pulling force. | 04-11-2013 |
20130169058 | WIRELESS POWER TRANSMISSION DEVICE - A wireless power transmission device includes a main body, a first position-limiting bulge, a second position-limiting bulge, and a closed transmitter coil. The first position-limiting bulge and the second position-limiting bulge are disposed within the main body. A space is defined between the first position-limiting bulge and the second position-limiting bulge. The closed transmitter coil is penetrated through the space. The two sides of the closed transmitter coil are respectively in contact with the first position-limiting bulge and the second position-limiting bulge, so that the closed transmitter coil is shaped as a dumbbell. Since the closed transmitter coil is shaped as a dumbbell, the magnetic flux can be uniformly generated by the electromagnetic effect when the closed transmitter coil is magnetized. Under this circumstance, the wireless charging efficiency is enhanced. | 07-04-2013 |
20130206945 | CLAMPING DEVICE - A clamping device is used for clamping an object. The clamping device includes a main body, an actuating mechanism, and two clamping arms. The actuating mechanism is disposed within the main body. The actuating mechanism includes a gear and cam, which are coaxial with each other. Each of the two clamping arms has an extension part. The two extension parts are engaged with two opposite sides of the gear. In a case that the engaging element is engaged with the cam, the two clamping arms are in an open status. In a case that the engaging element is disengaged with the cam, the gear is driven by the cam to be rotated. As the gear is rotated, the two extension parts are towed to be linearly moved. Consequently, the two clamping arms are switched from the open status to a clamping status. | 08-15-2013 |
20130257361 | WIRELESS CHARGING DEVICE - A wireless charging device includes a casing, a carrying member, and a first coil assembly. The casing includes a receiving space, an entrance side, and a supporting part. The carrying member includes a carrying plate, a first elastic structure, and a second elastic structure. The supporting part is disposed within the receiving space. The carrying member is located over the supporting part. The first coil assembly is fixed on the carrying plate. When the entrance side of the casing is fixed on a first surface of an object, the supporting part is presses against the first elastic structure and the second elastic structure, allowing the first elastic structure and the second elastic structure to be pushed by the first surface of the object and subject to deformation. Consequently, a balanced supporting force is generated to maintain a specified distance between the first coil assembly and the first surface of the object. | 10-03-2013 |
20140035381 | WIRELESS POWER TRANSMISSION DEVICE - A wireless power transmission device includes a circuit board, heat-dissipating plate, a closed transmitter coil, and an encapsulation member. The closed transmitter coil is disposed on the circuit board. The heat-dissipating plate is disposed on the circuit board. The circuit board, the heat-dissipating plate and the closed transmitter coil are sealed by the encapsulation member. Since no gaps are formed in the encapsulation member, the foreign liquid and dust are prevented from being introduced into the encapsulation member. Moreover, since portions of the heat-dissipating plate are partially protruded outside the encapsulation member and partially exposed outside the encapsulation member, the wireless power transmission device of the present invention has enhanced heat-dissipating efficiency. | 02-06-2014 |
20140139179 | WIRELESS CHARGING DEVICE - A wireless charging device includes a circuit board, a heat-absorbing plate, an inductive transmitter coil, and a casing. The inductive transmitter coil is disposed on the heat-absorbing plate. The heat-absorbing plate is disposed on the circuit board. The circuit board, the heat-absorbing plate and inductive transmitter coil are covered by the casing. The heat-absorbing plate includes at least one opening for increasing the entropy value of the heat-absorbing plate. | 05-22-2014 |
20140284226 | PROTECTING DEVICE FOR ELECTRONIC DEVICE - A protecting device for an electronic device is provided. The protecting device includes a first main body and a second main body. The first main body has a closed receiver coil for receiving electric power from a wireless power transmission device. The second main body is connected with the first main body, and slidable and swingable relative to the first main body. After the electronic device is stored in the protecting device, the second main body may be slid and swung relative to the first main body in order to expose a connecting port of the electronic device. Consequently, a connecting wire may be plugged into the connecting port. | 09-25-2014 |
20150069961 | WIRELESS CHARGING DEVICE - A wireless charging device for charging an electronic device is provided. Thee wireless charging device includes an adjustable bracket assembly and a wireless charging body. The wireless charging body is disposed on the adjustable bracket assembly. The adjustable bracket assembly includes a first bracket and a second bracket, wherein a relative position between the first bracket and the second bracket is adjustable. When a relative position between the first bracket and the second bracket is adjusted, a position of the electronic device supported on the adjustable bracket assembly is changed. Consequently, the wireless charging body is aligned with the electronic device to perform an efficient wireless charging operation on the electronic device. | 03-12-2015 |
