Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle-mounted audio device having a detachable panel operation unit, and more particularly to a vehicle-mounted audio device suitable for preventing an erroneous operation of a lock release knob for unlocking a panel operation unit.

[0002]

[Prior art]

 Conventionally, many detachable panel type on-vehicle audio devices having the structures shown in FIGS. 5 and 6 have been provided. FIG. 5 is a perspective view of the main body when the panel operation unit is detached, and FIG. 6 is a sectional view showing the lock release knob and the lock lever of the lock mechanism.

In the figure, reference numeral 1 denotes a main body of an on-vehicle audio equipment, and a front surface of the main body 1 has a panel mounting portion 1a for mounting and dismounting a panel operating portion (not shown) which is detachable. Reference numeral 3 is a lock lever of a lock mechanism for fixing the panel operation portion, and the lock lever 3 rotates around a fulcrum 3a. Reference numeral 10 denotes a lock release knob provided on the panel surface of the main body 1. The tip 10a of the lock release knob 10 contacts the lock lever 3 to drive the lock lever 3.

In the panel operation section of the detachable panel type configured as described above, the tip end 10a of the lock release knob 10 pushes the lock lever 3 by pushing the lock release knob 10, and the lock lever 3 serves as a fulcrum. By rotating around 3a, the lock lever 3 which has been locked to the panel operation section can be released and the panel operation section can be removed.

Originally, in order to prevent theft, the removable panel-type on-vehicle audio equipment is easily unlocked as described above because when the vehicle is parked and left from the vehicle, only the panel operation part is detached and brought back. The structure was such that the panel operation section could be freely attached and removed by operating knob 10.

[0006]

[Problems to be solved by the device]

 However, in the above-described conventional detachable panel type on-vehicle audio equipment, the lock release knob 10 is pushed by an unexpected malfunction while the main body 1 is being used, or the hands or body unintentionally come into contact with the lock release knob 10. There is a drawback that the panel operation part often comes off and falls against the user's will when the lock release knob 10 is pushed and operated.

In particular, there is a high risk that the panel operation unit may be detached and dropped from the main body 1 due to the above-mentioned erroneous operation while the vehicle is being driven, and the driver may panic and the vehicle operation may be neglected.

The present invention has been made in view of the above points, and the purpose thereof is to solve the drawbacks of the conventional example, and to provide a rib on the lock release knob to allow a push operation of the lock release knob due to an erroneous operation. We are providing the in-vehicle audio equipment that was impossible.

[0009]

[Means for Solving the Problems]

 The in-vehicle audio device of the present invention is equipped with a lock mechanism for fixing the panel operation unit to the in-vehicle audio device main body, and a lock release knob for releasing the lock mechanism by push operation on the main body. In an in-vehicle audio device having an operation section, a rib provided on the lock release knob and a fitting hole into which the rib fits are provided on the body panel surface, and the lock release knob is configured to be rotatable. The rib is fitted in the fitting hole to perform a push operation.

[0010]

[Action]

 According to this invention, a rib is provided on the lock release knob for releasing the lock mechanism for fixing the panel operation unit to the in-vehicle audio equipment main body, and when the rib of the lock release knob pushes the lock release knob, the main body panel is pressed. It can be pushed in by being fitted into the fitting hole on the surface.

On the other hand, even if the lock release knob is pushed by rotating the lock release knob for example at 90 degrees, the rib of the lock release knob comes into contact with the panel surface of the main body and the push operation cannot be performed. It becomes impossible to perform the unlocking drive of the lock lever that is locked by locking the operation part.

In this way, by rotating the unlocking knob to make the fixation and unlocking of the panel operating unit impossible, a malfunction or unintentional push operation of the unlocking knob is performed, and the panel operating unit is operated as in the conventional case. It is possible to prevent it from being detached and dropped without knowing it.

【Example】

 An embodiment of an in-vehicle audio device according to the present invention will be described with reference to FIGS. The same parts as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted. 1 is a perspective view of a main part, FIG. 2 is a sectional view showing a lock release knob and a lock lever, FIG. 3 is a sectional view showing a state where the lock release knob is pushed, and FIG. 4 is a lock release knob. It is sectional drawing which showed the state which Mi rotated.

In the figure, 1b is a fitting hole provided on the panel surface of the main body 1, 2 is a lock release knob, and a rib 2a is formed on the operating portion of the lock release knob 2, and the tip of the lock release knob 2 is formed. The portion 2b is in contact with the lock lever 3 inside.

When the panel operation unit (not shown) of the vehicle-mounted audio apparatus configured as described above is attached or detached, the rib 2a of the unlocking knob 2 is straightened to the fitting hole 1b on the panel surface as shown in FIG. When the lock release knob 2 is pushed as shown in FIG. 3, the rib 2a of the lock release knob 2 is fitted in the fitting hole 1b and the push operation is performed, and the tip 2b of the lock release knob 2 is locked by the lock lever. 3 is pressed, the lock lever 3 rotates about the fulcrum 3a, and the claw of the lock lever 3 that has been locked to the panel operation portion is released, and the panel operation portion can be detached.

When the panel operating portion is fixed to the panel mounting portion 1a of the main body 1 with the lock lever 3 and the vehicle acoustic device is used, the unlock knob 2 is rotated, for example, as shown in FIG. As shown in Fig. 4, when the lock release knob 2 is rotated about 90 degrees, the rib 2a of the lock release knob 2 comes into contact with the panel surface of the main body 1 and the lock release knob 2 cannot be pushed. That is, the push operation of the unlock knob 2 for unlocking the panel operation unit is fixed, and the panel operation unit cannot be released.

As described above, the unlocking operation of the unlocking knob 2 is controlled by the position of the rib 2a of the unlocking knob 2, and the unlocking knob is only at a position where the rib 2a position matches the fitting hole 1b on the panel surface. 2 can be pushed and the lock lever 3 can be unlocked. When the lock release knob 2 rotates and the position of the rib 2a and the position of the fitting hole 1b are different, the lock release operation cannot be performed.

That is, when the vehicle-mounted audio device is in use, the unlocking operation is disabled by setting the unlocking knob 2 in a rotated state, which causes a malfunction or carelessness of the panel operation unit as in the conventional case. It is possible to prevent the panel operation part from being detached and attached by pushing the lock release knob 2 by.

Further, by setting the rotation direction of the unlocking knob 2 to the left rotation direction, which is the reverse of the setting by the right rotation shown in FIG. 4, the rib 2a portion holds down the panel operating portion fixed to the panel mounting portion 1a. It is possible to attach the panel operation portion more firmly. Further, by using a mechanism (not shown) in which the above rib 2a locks and presses the panel operation part, the lock lever 3 for fixing the panel operation part can be omitted. It is also possible to construct the detachable panel type mechanism more simply.
