The present invention relates to a vehicle cradle of a portable radiotelephone, and in particular, a cradle for performing an on / off function when used in a hand free for an optional cradle of a portable radiotelephone. It is about.

Recently, due to the development of various communication facilities, portable wireless telephones (mobile phones) which can be always carried in order to meet the user's information needs are being used.In addition, due to the development of the electronic industry, the electronic components are gradually reduced in size and weight, The mobile phone, which has been reduced in volume and realizes multifunctionality, has been developed in order to pursue user convenience and to mount the mobile phone accordingly.

Furthermore, due to the development of mobile communication, a cradle of a mobile phone is installed when driving in various vehicles. In the case of the conventional mobile phone, a vehicle cradle 100 for fixing the mobile phone when used in a vehicle is shown in FIGS. 1 and 2. It became.

As shown in FIG. 2A, a fastener 3a which is inclined inwardly and protrudes in the vicinity of an upper case 1 for fixing a portable radiotelephone to the mounting portion 4 of the upper case 1, The push button 3 is integrally formed at the lower end, and the push button 3 is supported by the torsion spring 5, and the spring 5 is supported by the locking protrusion 6.

Also, as shown in FIG. 2B, the portable radiotelephone 80 is firmly fixed to the mounting portion 4 of the upper case 1, and at the same time, the inner side of the portable radiotelephone 80 is separated to detach when the portable radiotelephone 80 is detached. The ejector 7 is provided, and the ejector 7 has a structure in which a compression coil spring 8 is installed and supported.

According to the above configuration, the mobile radio telephone 80 is pressed down forcibly, and since the latch 3a is inclined to one side and protrudes, the latch 3a is retracted to the rear and is caught by the locking groove 81.

Since the latch 3a is extended by the phenomenon that the push button 3 is integrally protruded from the lower side and is supported by the torsion spring 5, the latch 3a moves forward again by the restoring force.

In addition, the upper end portion 7a of the ejector 7 ejecting on the mounting portion 4 simultaneously with the latch 3a is caught by the locking groove 81 is moved downward and disappears, and the lower end portion of the ejector 7 ( 7b) protrudes toward the upper surface of the support plate 9.

The ejector 7 has a large diameter portion formed therein, and a locking projection 7c is formed at its outer circumference to be supported by the compression coil spring 8 between the large diameter portion and the support plate 9, and the locking projection 7c is Limit the shanghai east of the ejector 7.

At this time, since the ejector 7 is supported by the compression coil spring 8, the ejector 7 has a restoring force to move upwards to support the bottom surface of the radiotelephone 80.

In this state, since the compression coil spring 8 is subjected to compression stress and the ejector 7 is continuously pushed upward, the vibration and shock of the vehicle are absorbed.

Therefore, the conventional vehicle cradle 100 performs a function of simply fixing the portable radiotelephone 80 to the cradle by simply attaching and detaching the mobile cordless phone 80 as a function of the clasp 3a and the ejector 7, and this structure is a charging terminal. In the structure of charging the battery using the it can be said that the performance of the ejector installed therein is sufficient.

However, in the structure of the vehicle cradle without a charging terminal, the inconvenience of having to turn on / off the operation of the hand free using a separate component manufactured independently occurs.

The present invention has been made to solve the above-mentioned problems, the object of the present invention is to perform the ejecting function and the sensing function at the same time by installing the optical sensor to operate by attaching the sensing unit to the ejector installed in the existing cradle By doing so, the hands free on / off operation is performed in the cradle without the charging terminal.

In order to achieve the above object, the present invention is a portable wireless device comprising an ejector coupled to a fixed device installed in the case for fixing the portable radiotelephone hand-free and securely fixed at the same time and easily separated at the time of departure In the vehicle cradle of the telephone, the ejector sensing unit is attached to the middle part of the ejector, and correspondingly the sensor is installed on the support plate to interact with the sensing unit.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

For convenience of description, like reference numerals designate like elements.

As shown in Figure 3, 4, the cradle 100 of the present invention is a portable radiotelephone 80 as a fixing device including a push button (3) and a torsion spring (5) in the case (1) as before Ejector 7 carried by the compression coil spring (8) is installed in order to firmly fix the cradle (100) to the cradle (100), and also to securely fix it and to easily detach it at the time of detachment.

The ejector 7 has a semicircular plate shape at the upper end portion 7a, a cylindrical portion at the lower end portion 7b, and has a locking projection 7c and a large diameter portion formed thereon so that the portable radio telephone 80 is seated on the mounting portion 4, The upper end 7a is pressed down and disappears, and the lower end 7b protrudes.

A compression coil spring 8 is installed between the upper end portion 7a and the lower end portion 7b to absorb the shock or vibration generated when the vehicle travels by holding the portable radiotelephone 80 by the ejector 7, and then the obstacles. The limited movement is comprised by the group 7c.

At this time, the ejector 7 of the present invention, unlike the shape of the conventional ejector, attaches the ejector sensing unit 30 additionally to the intermediate part, and correspondingly the optical sensor 20 on the support plate (9) sensor is installed to perform the operation by vertically reciprocating because the ejector 7 is supported by the compression coil spring 8.

Specifically, the ejector 7 is installed on the upper case 1 so that the up and down movement can be performed, and the printed board assembly (PBA) having the optical sensor 20 is installed on the support plate 9. Next, when the upper case 1 and the lower case 2 are combined, the ejector sensing unit 30 is positioned directly above the optical sensor 20.

Therefore, when the portable radiotelephone 80 is fixed to the holder 100, the portable radiotelephone 80 presses the upper end portion 7a of the ejector 7, and the ejector sensing unit moves downward to allow the optical sensor 20 to move. ) Is combined to perform the sensing function.

That is, the ejector sensing unit 30 contacts and detaches from the optical sensor 20 to perform the hand free on / off function.

As described above, the vehicle cradle of the present invention attaches the sensing unit to the existing ejector, and achieves the effect of simultaneously performing the ejecting function and the sensing function by installing an optical sensor on the support plate.
