Abstract

Provided is a vehicle cup holder allowing wireless charging. A vehicle cup holder allowing wireless charging according to an embodiment of the present invention comprises: a housing having an accommodation space for accommodating objects, including a portable telephone; a support unit coupled to the housing by means of a rotational shaft to allow rotation in the accommodation space, and comprising a wireless transmission module for wirelessly charging the battery of a portable telephone; a sensing unit for sensing input signals from a user or the proximity of a portable telephone; and a driving unit for providing driving power to the rotational shaft so as to allow the position of the support unit to be changed, on the basis of a signal sensed by the sensing unit, to a charging position in which the portable telephone can be charged, or to a standby position in which an object can be accommodated in the accommodation space.

First claim

The invention claimed is:

1. A vehicle cup holder allowing wireless charging, comprising:
a housing which has an accommodation space, in which an object including a portable terminal is accommodated, formed therein;
a mounting unit which is coupled to the housing through a rotation shaft so as to be rotatable in the accommodation space and which includes a wireless power transmission module configured to wirelessly charge a battery of the portable terminal;
a sensing unit which detects an input signal of a user or detects proximity of the portable terminal; and
a driving unit which provides a driving force to the rotation shaft based on a signal detected by the sensing unit such that the mounting unit is shifted to a charging position at which the battery of the portable terminal is charged or a standby position at which the object is accommodated in the accommodation space.

2. The vehicle cup holder of claim 1 , wherein the charging position is a position at which one surface of the mounting unit is disposed to be inclined at an acute angle with respect to a bottom surface or a side surface of the accommodation space so as to support one surface of the portable terminal, and
the standby position is a position at which the one surface of the mounting unit is disposed in a state parallel to the side surface of the accommodation space.

3. The cup vehicle holder of claim 1 , wherein the sensing unit is a proximity sensor configured to detect a user's movement or a touch sensor configured to detect a user's touch.

4. The vehicle cup holder of claim 3 , wherein the sensing unit is disposed in the housing so as to be positioned outside the accommodation space.

5. The vehicle cup holder of claim 1 , wherein the sensing unit is a near field communication (NFC) antenna embedded in the mounting unit to recognize an NFC signal transmitted from the portable terminal.

6. The vehicle cup holder of claim 1 , wherein the rotation shaft includes a first rotation shaft and a second rotation shaft which protrude outward from both sides of the mounting unit by a predetermined length, and
the driving unit includes a driven gear axially coupled to the first rotation shaft, a driving motor mounted in the housing, and a drive gear axially coupled to the driving motor and engaged with the driven gear.

7. The vehicle cup holder of claim 6 , further comprising a malfunction prevention unit configured to shift the mounting unit to the standby position by detecting a state in which the object is accommodated in the accommodation space when the mounting unit is rotated from the standby position to the charging position.

8. The vehicle cup holder of claim 7 , wherein the driving unit further includes a first member axially coupled to a rotation shaft of the driving motor, a second member axially coupled to the drive gear and having an opposite surface facing the first member, a first joint member disposed between the first member and the second member and axially coupled to the rotation shaft of the driving motor, a second joint member disposed between the first member and the second member and axially coupled to the drive gear, and a spring member of which one end portion is fixed to the first joint member, and the other end portion is fixed to the second joint member, and which is disposed to surround circumferential surfaces of the first joint member and the second joint member, and
the malfunction prevention unit includes a Hall sensor mounted on one surface of the first member and a magnet member mounted on one surface of the second member.

9. The vehicle cup holder of claim 1 , wherein the mounting unit includes a case having an interior space in which the wireless power transmission module is disposed, and a connection board disposed in the interior space and electrically connected to the wireless power transmission module,
the rotation shaft has a through-hole formed to pass therethrough in a length direction thereof, and
the connection board includes a first part disposed in the interior space and a second part disposed to pass through the through-hole such that a portion thereof is exposed to the outside and a cable is connected thereto.

10. The vehicle cup holder of claim 9 , wherein the mounting unit includes at least one protrusion protruding from an inner surface of the case so as to support one surface of the wireless power transmission module.

11. The vehicle cup holder of claim 1 , further comprising another wireless power transmission module embedded in a bottom surface of the accommodation space,
wherein, in a state in which the mounting unit maintains the standby position, the another wireless power transmission module transmits wireless power to the object inserted into the accommodation space.
