At this time, since the elastic button 154 is installed in the elastic button side guide slots 125 and 132 by interference fit, it stops at the position adjusted by the user.

According to another embodiment of the present invention, the elastic button 154 has a side tooth 156 for engaging with the fixed side tooth 135 formed on the elastic button side guide slot 125 on the side surface. When the movable side teeth 156 of the elastic button 154 are engaged with the fixed side teeth 135 formed in the elastic button side guide slot 125, the slider 150 does not move and remains fixed at the current position do. If the user presses the elastic button 154 in the lateral direction of the slider case 152 so that the movable side tooth 156 of the elastic button 154 is engaged with the fixed side tooth 135 formed in the elastic button side guide slot 125, The slider 150 can move in the vertical direction of the apparatus holder 110. The moving teeth 156 of the resilient button 154 and the resilient button side guide slot 154 of the resilient button 154 can be removed by moving the slider 150 in accordance with the position of the power receiver of the portable electronic device, And the fixed side teeth 135 formed on the upper surface 125 are engaged with each other. Accordingly, the slider 150 to which the wireless charging module 151 is attached can not move and remains fixed at the current position adjusted by the user.

According to another embodiment of the present invention, the elastic button 154 can be configured to be elastically deformable in the lateral direction of the slider case 152. [ That is, a space 158 is formed between the plate 157 to which one end of the elastic button 154 is fixed and the side surface of the slider case 152, and both ends of the plate 157 are fixed to the slider case 152 . When the user presses the elastic button 154 in the lateral direction of the slider case 152, the plate 157 is brought into close contact with the side surface of the slider case 152 and the moving side teeth 156 of the elastic button 154 are elastically Side tooth 135 formed in the button-side guide slot 132. [0054] When the movable side teeth 156 and the fixed side teeth 135 are separated as described above, the slider 150 can be easily moved in the vertical direction of the device holder 110 along the elastic button side guide slot 132.

9 is a perspective view showing a device holder of a portable terminal equipped with a wireless charging cradle according to the present invention.

First, the wireless charging cradle 100 is installed with the link assembly 160 in the second through hole 120a of the base plate 120. [ The link assembly 160 includes a first link 161 having a ball fixed at one end and a receptacle at the other end, and a second link 162 rotatably connected to the ball at one end. And the third link 163 is rotatably connected to the other end of the second link 162.

The pedestal 170 includes a body 171, a suction plate 172 fixed to a lower portion of the body 171, a lever (not shown) for pressing the suction plate 172 to fix the pedestal 170 to a dashboard or a window 173). The body 171 is provided at its upper portion with a link connection portion 174 for receiving and rotatably fixing one end of the link assembly 160. The third link 163 is rotatably connected to a link connecting portion 174 formed on the upper portion of the body 171.

As described above, the device holder is attached to the dashboard of the vehicle and the portable terminal is stably mounted to the device holder of the wireless charging cradle. The slider having the wireless charging module installed in the wireless charging cradle can be freely moved up and down in the device holder in accordance with the position of the power receiver of the wirelessly chargeable portable terminal mounted on the device holder. Accordingly, the distance between the power receiver of the portable terminal mounted on the wireless charging cradle and the wireless charging module, which is a power transmitter, is narrowed to improve the transmission efficiency.
