3 to 6, the cover portion 30 according to the present embodiment may include a cover portion 31 including an outer cover 31 and an inner cover 33, and a support portion 35 .

When the cover portion 30 is closed to the receiving portion 20, the outer cover 32 of the cover portion 31 is exposed to the outside. Accordingly, the outer cover 31 may be a plate disposed on the outermost side of the cover portion 30. [

The outer cover 31 may include a wireless charging module (60 of FIG. 7) therein. The wireless charging module 60 can charge the battery of the portable terminal 1 by wirelessly transmitting energy.

The wireless charging module 60 can be embedded in the outer cover 31. [ For example, the wireless charging module 60 can be completely embedded in the outer cover 31 so that it can not be visually recognized from the outside. However, the configuration of the present invention is not limited thereto, and it is possible to constitute it so as to be partially exposed if necessary.

7 is a perspective view schematically illustrating a wireless charging module according to an embodiment of the present invention. The wireless charging module 60 may be formed of a coil part 65 including at least one coil 66 and a circuit part 62 supplying current to the coil part 65. [

The coil portion 65 forms a magnetic field under the control of the circuit portion 62 and radiates radio power into the atmosphere. To this end, one or more coils 66 may be attached to the coil section 65 on the substrate 67. Here, the coil 66 may be a wire-shaped coil, but the present invention is not limited thereto. The coil 66 may be formed on the substrate in the form of a conductor pattern, or may be formed using a coil formed by a flat wire.

The circuit portion 62 can be formed by mounting a plurality of electronic elements 61 on a circuit board 63 and includes a circuit for controlling charging. Therefore, the coil part 65 emits electric power under the control of the circuit part 62 and transmits electric power to the portable terminal.

The circuit portion 62 is electrically connected to the coil portion 65 by the connecting portion 68. At this time, the connection portion 68 may be formed of a wire-shaped conductor or may be formed of a flexible substrate.

The wireless charging module 60 according to the present embodiment is configured such that the circuit portion 62 and the coil portion 65 are formed in the form of a thin plate and the outer cover 31 is stacked in a stacked state, . At this time, the wireless charging module 60 is embedded in the outer cover 31 such that the coil 66 of the coil portion 65 is disposed on the inner surface side of the outer cover 31, that is, on the insertion space 40 side.

 The overall area of the wireless charging module 60 corresponds to the area of the circuit portion 62 and the coil portion 65 and the thickness can be formed to the entire thickness of the circuit portion 62 and the coil portion 65. [

The wireless charging module 60 is placed in the outer cover 31 without expanding the area of the conventional cup holder unit cover by embedding the circuit portion 62 and the coil portion 65 in the outer cover 31 in a superposed state .

On the other hand, due to the thickness of the wireless charging module 60, the thickness of the outer cover 31 can also be increased. However, this can be reduced by minimizing the thickness of the wireless charging module 60, such as forming the coil portion 65 into a thin film coil.

The inner cover 33 is engaged with the inner surface of the outer cover 32. At this time, as shown in Fig. 6, a part of the support portion 35 is inserted between the inner cover 33 and the outer cover 32. As shown in Fig.

A space in which the insertion portion 39 of the support portion 35 can be disposed may be provided between the inner cover 33 and the outer cover 32. In addition, (50) is inserted and arranged.

The interlocking member 50 is formed of a gear having a through hole formed therein and having teeth on the outer circumferential surface thereof and is rotatably fitted to a guide cylinder 32a formed on the inner surface of the outer cover 32. [

The supporting portion 35 is engaged with the teeth of the interlocking member 50 in an engaged manner. Therefore, the interlocking member 50 is rotated in accordance with the movement of the support portion 35.

The support portion 35 is provided to stably hold the portable terminal when charging the portable terminal.

To this end, a part of the support portion 35 is inserted between the outer cover 31 and the inner cover 33 and is coupled to the cover portion 31. Therefore, the support portion 35 is disposed on one side of the lid portion 31 and is disposed in the storage space 21 when the lid portion 31 is closed.

The inner cover 33 is provided with a coupling groove 33a which is a space through which the support portion 35 is coupled. Accordingly, the supporting portion 35 defines a moving distance corresponding to the size of the engaging groove 31a.

 The supporting portion 35 according to the present embodiment may include the first to third supporting portions 35a, 35b and 35c.

The first and second support portions 35a and 35b are disposed to be spaced apart from each other as far as they are opposed to each other and are coupled to the lid portion 31 so as to be movable. At this time, the moving directions of the first and second support portions 35a and 35b may be a direction in which they are close to each other or a direction in which they are distant from each other. That is, the direction of movement of the first and second support portions 35a and 35b may be defined as a direction toward or away from the center of the lid portion 31.

The third support portion 35c is disposed between the first and second support portions 35a and 35b and is arranged to be movable in a direction perpendicular to the moving direction of the first and second support portions 35a and 35b.

The third support portion 35c is disposed at a position adjacent to the rotation axis P of the cover portion 30 so as to be coupled to the lid portion 31 so as to be movable toward or away from the center of the lid portion 31. [ do.

The first to third support portions 35a, 35b and 35c each have an insertion portion 39 inserted into the lid portion 31, an extension portion extending from the insertion portion 39 to the outside of the lid portion 31 38 and a protrusion 37 extending from the end of the extension 38 toward the center of the lid 31. [

The space formed between the lid 31 and the projections 37 of the first to third supports 35a, 35b and 35c is formed as a space into which the portable terminal 1 can be inserted.

The distance between the lid 31 and the protrusion 37 can be defined by the length of the extension 38 and the maximum thickness of the mobile terminal 1 inserted between the lid 31 and the protrusion 37 . ≪ / RTI >

The insert portion 39 is elongated along the surface direction of the lid portion 31 at the extended portion 38 and formed at one side with teeth that mesh with the teeth of the interlocking member 50. Thus, the interlocking member 50 and the insert 39 are coupled together in the form of rack and pinion gears.

The insertion portions 39 of the first to third supporting portions 35a, 35b and 35c are arranged such that the teeth are all engaged with the teeth of the interlocking member 50. Therefore, when the interlocking member 50 is rotated, the first to third supporting portions 35a, 35b and 35c are simultaneously moved.

For example, in FIG. 6, when the interlocking member rotates in the R direction, as shown in FIG. 4, the first to third supporting portions 35a, 35b and 35c move in a direction approaching each other, The terminal is held by the first to third support portions 35a, 35b, 35c.

On the other hand, when the interlocking member 50 rotates in the L direction in FIG. 6, as shown in FIG. 3, the first to third supporting portions 35a, 35b and 35c move in directions away from each other, 1 to the third supporting portions 35a, 35b, 35c are spaced apart from the portable terminal, the user can easily take the portable terminal from the wireless charging apparatus 100. [

Similarly, when the user moves one support portion (e.g., the first support portion), the support portion 35a rotates the interlocking member 50 in the moving process, and the other support portions 35b, 35c also move together.

Therefore, even if only one supporting portion 35a is moved, all other supporting portions 35b and 35c are moved together, and insertion and removal of the portable terminal in the insertion space 40 is very easy.

The first to third supporting portions 35a, 35b and 35c may be elastically coupled to the lid portion 31 through the elastic coupling portion 80. [

The elastic coupling portion 80 may elastically connect the insertion portion 39 of the first to third supporting portions 35a, 35b and 35c with the lid portion 31. [ Therefore, when the supporting portion 35 is moved away from the center of the lid portion 31 by an external force applied to the first to third supporting portions 35a, 35b and 35c, the elastic coupling portion 80 becomes elongated and elastically deformed. Therefore, elastic force for moving the center of the lid part 31 is continuously applied to the support part 35, so that the portable terminal inserted in the insertion space 40 can be firmly supported.

The elastic coupling portion 80 may be variously used as long as it is a member capable of providing an elastic force such as a spring or a rubber member. For example, the elastic coupling portion 80 can be constructed by connecting the insertion portion 39 and the outer cover 32 with a coil spring.

In the present embodiment, as shown in FIG. 6, the first supporting portion 35a and the outer cover 32 are connected to each other by using one elastic coupling portion 80. In this case, as shown in FIG. However, the present invention is not limited thereto, and various modifications may be made as necessary, for example, by arranging the elastic coupling portions 80 with respect to all the supporting portions 35a, 35b, 35c.

In addition, the wireless charging apparatus 100 according to the present embodiment may include a buffer member 70.

The cushioning member 70 is attached to the inner surface of the outer cover 31 and the protrusion 37 facing the outer cover 31 to prevent slipping of the portable terminal and prevent scratches on the portable terminal.

Therefore, the buffer member 70 may be formed in the form of a pad, a block, or a band of a rubber material or a sponge material, but is not limited thereto.

The vehicle wireless charging apparatus according to the present embodiment configured as described above can wirelessly charge the battery of the portable terminal while storing the portable terminal in a cup holder cover provided in most vehicles, have. In addition, since the portable terminal can be securely fixed and fixed so as not to be shaken, the charging efficiency can be increased.

In addition, since the portable terminal is always positioned at the center of the wireless charging module by the supporting portion, the charging efficiency can be increased.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be obvious to those of ordinary skill in the art.
