Description

[0001] The present invention relates to a smart phone holder for a vehicle,

The present invention relates to a smartphone holder for a vehicle, which is easily fixed to a grill of a tuyere, and is capable of easily adjusting a left-right angle of a rotary support on which a smartphone is mounted, The present invention relates to a smartphone holder for a vehicle,

In the modern society, various devices such as mobile phones, DMB, GPS, and smart phones are increasingly used regardless of places due to the rapid development of electronic communication equipment and information communication. In particular, smart phones can be used for various functions such as camera, audio, video playback and navigation by installing various applications, so that a smart phone holder for mounting a smartphone in the vehicle is installed.

Generally, a smart phone cradle is largely used as an adsorption cradle for attaching and fixing to a front glass, an attachment type cradle for attaching to a dashboard with an adhesive pad, and a clamp type cradle for connecting and fixing to a vehicle cradle .

The adsorption table is attached to the inner surface of a window by using an air compression unit. In addition to the difficulty in adhering operation, it often occurs that compressed air is released during expansion or contraction due to temperature difference during use. Is disturbed as well as being distant from the driver, so that the operation posture is disturbed when the smartphone is operated, which is a cause of an accident.

The adhesive type pad is fixed to the dashboard by the adhesive force of the adhesive pad. Once the adhesive pad is fixed, it can not be reused and the place can not be moved. In addition, when the adhesive pad is elongated, the adhesive pad remains on the surface of the dashboard So that the problem of poor cosmetic appearance occurred.

In particular, the adsorption mount and the mount stand may cause a phenomenon that the temperature inside the vehicle rises or falls from the glass window or the dashboard due to the thermal change when the temperature falls in the winter season, which may adversely affect the safety driving of the user Lt; / RTI >

The clamp type cradle is a clip type in which a clip capable of engaging with a portable device is fixed to the front of the cradle by inserting the clip into the cradle grill. The clamp type cradle, which is conventionally used, Is not firmly coupled to the grill of the tuyeres, and the shake (gap) phenomenon is generated. In addition to the vibration of the vehicle due to the imperfect fixation, There is a problem in that a phenomenon of being separated from the air outlet grill occurs when an impact or the like is generated.

Particularly, since the shape, angle, and direction of each vehicle differs in shape, angle, direction, and the like, it is difficult to install the mobile phone in a simple clip manner depending on the vehicle. Even if the smartphone mount is installed in the air outlet, Or the smartphone can not be operated while the occupant is seated on the seat.

Patent Registration No. 10-1902424 (2018.09.19) Patent Registration No. 10-1854099 (Aug. 25, 2014) Published Patent Publication No. 10-2018-0040317 (Aug. 20, 201) Patent Registration No. 10-1493433 (Feb.

It is an object of the present invention to improve the convenience of the user by freely adjusting the rotation angle of the rotary support in the left and right direction by firmly fixing the fixed support to the vehicle air outlet grill and spline coupling of the rotary support and the fixed support, The present invention provides a smartphone holder for a vehicle that can easily adjust a turning angle in a left and right direction.

The hook 342 may be made of a high-strength synthetic resin material such as a thin metal or engineer plastic so that the hook 342 can be inserted between the tuyere grilles 510, though the material thereof is not particularly limited.

4, the spring 400 is supported on one side of the cylindrical guide base 333 of the holder, and the other side of the spring 400 is held in contact with the rotary support 225 of the rotary support. And is installed in the assembly hole 240 so as to be positioned around the mounting hole 321.

The spring 400 thus installed elastically presses the rotary support 200 about the holder 330 so that the spline 226 of the rotary support is splined with the spline 323 of the hook housing to rotate in the left- I.e., a function of fixing the angle in the left-right direction of the rotary support. That is, the spring 400 has an elastic force for pressing the rotary support 200 in the tip direction A.

Hereinafter, the operation state of the present invention constructed as above will be described with reference to the accompanying drawings.

FIG. 11 is a view illustrating an operating state of the fixed support according to the present invention. When the hook is pushed between the air guide grilles so that the contact pad is in close contact with the air guide grille, and the lever is rotated, The hook ring is slidably moved in the front end direction, and the contact pad, the hook ring, the hook guide block, and the grill support are brought into close contact with the grill of the air outlet so that the position of the fixed support is fixed.

At this time, the rotary support to which the cradle is connected is elastically pressed in the direction of the tip by the spring and is spline-coupled with the hook housing of the fixed support, so that it is fixed on the fixed support.

12 is a view illustrating an operating state of the rotary support according to the present invention. When the rotary support is pushed in the backward direction in a state where the position of the fixed support is fixed to the rotary grill, the spring is compressed, The spline of the rotary support is released from the spline of the hook housing, so that the rotation support and the hook housing are disengaged from each other. At this time, the spline and the flange of the hook housing are positioned in the fitting hole and the clearance hole in the assembly hole.

When the rotary support body is freed from the hook housing of the stationary support body, the rotary support body is rotated to the left or right by a required angle, and then the force applied to the rotary support body is removed. So that the splines of the rotary support are splined to the splines of the hook housing. (Fixed angle of the rotating support)

At this time, the spline of the rotary support body is formed so that the cross-sectional area of the spline protrusion increases as it goes from the front end to the rearward direction, and the groove area of the spline groove decreases as it goes from the front end to the rearward direction,

The spline of the hook housing is formed such that the cross sectional area of the spline projection increases from the rear end to the front end direction and the groove area of the spline groove decreases from the rear end to the front end direction, The spline coupling between the rotating support and the hook housing is facilitated.

Further, the present invention is such that the rotary support and the hook housing are splined to each other, so that the rotary support can be rotated at a necessary angle within a range of 360 degrees in one direction.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
