Description

KNOB UNIT OF MULTIMEDIA SYSTEM FOR VEHICLE}

The present invention relates to a knob unit of a multimedia system for a vehicle, and more particularly, to a knob unit of a multimedia system for a vehicle that can improve the operability of a user and reduce the risk of injury in an accident.

In general, the crash pad of the vehicle is provided with a multimedia system for viewing or listening to TV, audio, navigation, etc. for the convenience of passengers including the driver.

At this time, the knob is provided to adjust the volume (volume) or tune (tune) of the TV, audio, etc. In Europe, the height of the knob is regulated by the regulation item of the crash safety law.

In other words, when the height of the knob is high, the occupant may be injured by the protruding knob during an accident, so that the height of the knob is 0.95 cm or less relative to the entire curved surface while the knob is pushed to reduce the risk of injury to the occupant.

By the way, when the height of the knob is lowered so as not to deviate from the above regulation, it is difficult for the user to operate the knob and there is a problem that the operability is deteriorated.

Accordingly, it is an object of the present invention to provide a knob unit of a multimedia system for a vehicle that can prevent injuries of an occupant and improve the operability of a knob.

According to the knob unit of the vehicle multimedia system of the present invention, the object and the head unit fixed body consisting of a rotating hook extending from the body and the first fixing jaw and the second fixing jaw are formed on the outer peripheral surface in turn; A knob having a rotation pin coupled to the center and having an insertion portion for inserting the rotation hook; One end is coupled to the inner surface of the insertion part so as to protrude outward, and is achieved by a rotating arm having a locking part that is sequentially caught by the first fixing jaw and the second fixing jaw at the end.

Here, the circumference of the rotary arm is preferably coupled to the spring for pressing the rotary arm inward.

At this time, the rotating arm is preferably made of a soft material of the degree that can be opened to the outside when the knob passes the second fixing jaw beyond the first fixing jaw.

As described above, according to the present invention, when the impact is applied to the knob, the knob is configured to be further inserted from the first jaw to the second jaw, thereby satisfying the European crash safety regulations regulating the height of the knob. In addition, it is possible to prevent injury to the occupant and the knob unit of the vehicle multimedia system is convenient for use because the knob is high enough when the locking portion is fixed to the first fixing jaw.

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

1 is a side separation view schematically showing a knob unit of a multimedia system for a vehicle according to the present invention, (a) is a perspective view showing the knob of FIG. 1, (b) is a front view of (a), Knob unit 1 of the multimedia system for a vehicle according to the invention is largely composed of a head unit fixture (10) connected to the encoder, the head unit fixture (10) and the knob 30 for the user to push or rotate do. When the knob unit 1 functions to operate the volume of the audio, for example, when the knob 30 is pressed, power comes on, and when the knob 30 is rotated to the right, the volume increases and the knob ( Rotate 30) to the left to lower the volume.

The head unit fixture 10 includes a body 11 and a rotation hook 12 extending from the body 11 and having a first fixing jaw 21 and a second fixing jaw 22 sequentially formed on an outer circumferential surface thereof.

Rotating hanger 12 is coupled to the encoder coupled, when the knob 30 is rotated in conjunction with the rotary pin 33, the signal is converted by the encoder when the knob 30 is rotated to the right or left, the volume is increased It can be higher or lower.

At this time, the first fixing jaw 21 and the second fixing jaw 22 are sequentially formed on the outer circumferential surface of the rotary hook 12, and the first fixing jaw 21 and the second fixing jaw 22 are When the user pushes the knob 30 is caught with the engaging portion 41 of the rotary arm 40 to be described later. That is, when the user pushes the knob 30 in the normal operation, the locking portion 41 is first fixed through the first fixing jaw 21. In this state, additional external force is applied to the knob 30 due to an accident. When applied, the locking portion 41 passes the second fixing jaw 22 and goes through a process of contacting the body 11. Therefore, after the knob 30 is primarily fixed, it can be additionally inserted by the distance from the first fixing jaw 21 to the body 11 to satisfy the height of the knob 30 regulated in Europe. In addition to preventing injuries, when the knob 30 is primarily fixed, the height of the knob 30 is sufficiently high, so that the knob 30 can be easily operated.

Knob 30 is for the user to push or rotate, in the center is coupled to the rotary hook 12 is coupled to the rotary pin 33 for rotating the rotary hook 12. In addition, the center portion of the knob 30 is formed with an insertion portion 31 for inserting the rotary hook 12 on the upper and lower sides with respect to the rotary pin 33.

The inner side of the insertion portion 31 is provided with a rotating arm 40 is coupled to one end protruded outward, the first fixing jaw 21 and the second fixing jaw 22 at the end of the rotating arm 40 ) Is formed in the engaging portion 41 in turn.

Rotating arm 40 is made of a soft material enough to open to the outside when a strong impact is applied to the knob 30 is preferably prevented from being broken by the impact, at this time around the rotary arm 40 The spring 50 for pressing the rotating arm 40 inward is coupled.

By such a configuration, the operation process when the knob 30 of the knob unit 1 of the vehicle multimedia system according to the present invention is pushed will be described briefly with reference to FIGS. 3 to 5.

When the knob 30 is normally pushed, the locking portion 41 is caught by the first fixing jaw 21 as shown in FIG. 3.

Then, when an additional external force is applied to the knob 30 by an accident or the like, the locking portion 41 is over the second fixing jaw 22 as shown in Figure 4, wherein the rotating arm 40 is soft Since the locking portion 41 is made of a material is opened to the outside by the pushing force.

Next, when an additional external force is continuously applied to the knob 30, the locking portion 41 is completely beyond the second fixing jaw 22 and comes into contact with the body 11 as shown in FIG. 5 to enter the height of the collision safety regulation. At this time, the rotary arm 40 is pressed inward by the force of the spring 50 is positioned in the original state.

As described above, according to the present invention, the knob 30 is configured to be further inserted (see FIGS. 4 and 5) in the normal fixed position (see FIG. 3) when an impact is applied to the knob 30. By doing so, it is possible not only to satisfy the European crash safety regulations regulating the height of the knob 30, but also to prevent injuries of the occupants, since the knob 30 is sufficiently high in the normal fixing position. It is convenient to use.
