1 is an exploded perspective view illustrating a vehicle holder of a portable terminal according to a first embodiment of the present invention, Figure 2 is a perspective view showing a vehicle holder of a portable terminal according to the first embodiment of the present invention. As shown, the vehicle cradle 100 of the portable terminal according to the first embodiment of the present invention is installed in the vehicle and provided on the cradle 110 and the cradle 110 on which the main body 1 of the portable terminal is mounted. It comprises a sliding coupling portion 120 and the vibration absorbing means 130 is installed in the sliding coupling portion 120.

On the other hand, the portable terminal mounted by the vehicle cradle 100 of the portable terminal according to the present invention includes a navigation (portable media player), personal digital assistants (PDA), digital multimedia broadcasting (DMB) player, MP3 ( MPEG audio layer-3) Includes players, electronic dictionaries, mobile phones, as well as miniaturized electronics for portable use.

The cradle 110 is a cradle 111 having a mounting portion 111a is detachably coupled to the support 112 so that the main body 1 of the portable terminal is detachably coupled thereto, and the support 112 is installed in a vehicle interior. do.

The cradle 111 and the support 112 are each formed with a coupling groove 111b and a coupling piece 112a to be detachably coupled to each other, and inserts the coupling piece 112a formed by the letter “a” into the coupling groove 111b. By changing the direction at right angles to the cradle 111 is fixed to the support 112 to prevent the departure from the front.

The support 112 is a ball made of a ball housing 112c in which the ball 112b and the ball 112b are rotatably mounted inward so that the portable terminal can be rotated in the vertical and horizontal directions along with the cradle 111 in the middle. Joint couplings are provided.

The support 112 is installed in the vehicle interior by an attachment member 112d provided at an end to be installed in the vehicle interior. The attachment member 112d may be a double-sided tape, but is easily removable as in the present embodiment. It is preferable that the adsorbing plate is made.

Sliding coupling portion 120 is provided in the cradle 110 is made of the first and second coupling members (121, 122) that are slidingly coupled to each other located on the inside and outside, for example, the first coupling member 121 of the tube shape It is inserted to be slidable inside the second coupling member 122. At this time, in order to prevent the first coupling member 121 from being separated from the outside in the state of being inserted into the second coupling member 122, the locking jaw 121a is formed at the bottom of the first coupling member 121 and the first coupling member 121 is formed. The cap 123 fitted to the coupling member 121 is screwed to the end of the second coupling member 122.

Vibration absorbing means 130 is installed in the sliding coupling portion 120 to absorb the vibration or shock applied to the cradle 110 by applying a damping force to the first and second coupling members (121, 122).

The vibration absorbing means 130 is a first coil spring having both ends elastically supported by the first and second coupling members 121 and 122 in the first embodiment, and may be inserted into the second coupling member 122. As in the first coupling member 121 has a tube shape similar to the second coupling member 122 is mounted inside the first and second coupling members 121, 122, both ends of the first and second coupling members 121, 122, respectively Elastic support.

Therefore, the vehicle cradle 100 of the portable terminal according to the first embodiment of the present invention is the compression when the sliding coupling portion 120 is compressed or vice versa as shown in Figure 3 by the vibration or shock applied from the vehicle It is absorbed by the elastic force applied from the vibration absorbing means 130, which is the first coil spring, thereby preventing damage to the portable terminal and suppressing an impact on the coupling portion between the main body 1 and the cradle 110 of the portable terminal. Prevent occurrence.
