Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for an inching switch for performing creep operation in an automatic vehicle equipped with an automatic transmission.

[Prior Art] A mechanism is known that actively incorporates the creep phenomenon of an automatic vehicle to cause the automatic vehicle to move in increments. An inching switch for this purpose is provided near the selector lever. This inching switch is activated when the engine is started and the lever is in R or D position.
When the vehicle is in the range and the accelerator pedal is not depressed, if you turn it on, the vehicle will start to slide.
Set the vehicle speed to an appropriate speed for parking in a garage, driving at the slowest speed, etc.

The conventional inching switch mounting structure is to store the inching switch in a switch box and to prevent the driver from accidentally operating it or turning it on against the driver's wishes. It had a structure with a cover attached to the box. The switch was operated using a two-operation method in which the switch was turned on only after opening the cover and pressing the switch button inside (for example, Utility Model No. 61-97035).

[Problem to be solved by the invention] However, with this method of mounting an inching switch, although the elastic force of the spring for restoring the switch cover is large, the switch button is small and
Moreover, the button had to be pressed while pushing the cover open, making it difficult to operate.

The purpose of the present invention is to provide a mounting structure for an inching switch for an automatic vehicle, which prevents the driver from inadvertently turning on the switch and starting the vehicle, and which makes it easy to turn on the switch. .

[Means for Solving the Problems] In order to achieve the above object, the present invention integrally forms a switch cover and an inching switch. More specifically, as shown in FIGS. 1 to 4, the present invention includes a case 2 provided in the driver's seat of an automatic vehicle and having an opening 2a for an inching switch, and a case 2 inside the case 2. A case 2 includes a switch box 3 provided below the opening 2a and having an open top, an inching switch 4 provided within the box 3 for causing the automatic vehicle to perform a creep operation, and a case 2 having a protrusion 5a on the surface. opening 2
The switch cover 5 is provided with a switch cover 5 which is slidably provided inside the case 2. After the protrusion 5a slides on the opening 2a of the case 2, the switch cover 5 is placed in a state where the protrusion 5a is in contact with one end of the opening 2a. It is installed so that it can be lowered into the interior. The switch button 4a of the inching switch 4 is pressed down when the switch cover 5 is lowered. The switch box 3 is characterized in that a spring 7 is provided within the switch box 3 to urge the lowered switch cover 5 to rise and come into contact with the other end of the opening 2a.

[Function] When the switch cover 5 is not slid, the switch cover 5 cannot be pushed down and the inching switch 4 will not be turned on. When the switch cover 5 is slid and comes into contact with one end of the opening 2a, the switch cover 5 can be lowered and the switch button 4 can be lowered.
When a is pressed down, the inching switch 4 is turned on.

[Example] Next, an example of the present invention will be described in detail based on the drawings. 1 and 2, a selector lever 1 is provided at the driver's seat of an automatic vehicle, passing through a display case 2 that displays its selected position. The display case 2 has an opening 2 for the inching switch.
a is provided. Inside the display case 2 below this opening 2a is a switch box 3 whose top is open.
will be provided. An inching switch 4 for causing the automatic vehicle to perform a creep operation is attached to the inner bottom of the box 3 with a screw 4b. Above this switch 4 is a switch cover 5.
is provided so as to be able to slide on the inner surface of the opening 2a of the display case 2.

The switch cover 5 has a protrusion 5a projecting from the opening 2a on its front surface, sliding portions 5b and 5c on both sides of its back surface, and a switch pressing portion 5d approximately in the center of the back surface. Sliding part 5 of switch cover 5
A fan-shaped cover support plate 5f is provided near c. The sliding parts 5b and 5c are the opening 2 of the display case 2.
It slides on the sliding guide parts 2b and 2c provided on the mutually facing edges of a.

As shown in FIG.
a is disengaged from the sliding guide portions 2b, 2c while in contact with one end of the opening 2a of the display case 2, and is provided so as to be able to descend into the box 3. Further, in this state, the switch pressing portion 5d is located above the inching switch 4, and the switch cover 5 is positioned above the inching switch 4 as shown in FIG.
is lowered, press switch button 4 of inching switch 4.
It is designed to push down on a.

Returning to FIG. 2, the support plate 5 of the switch cover 5
A rotation shaft 6 is fixed to the lower end of f. This rotation axis 6
A coil spring 7 is wound around. One end of the spring 7 is fixed to the rotating shaft 6, and the other end presses against the inner bottom surface of the switch box 3, and the spring 7 is fixed to the rotating shaft 6.
support. The spring 7 raises the lowered switch cover 5 and closes the opening 2a of the display case 2.
Force it to come into contact with the other end.

Next, a method of operating the inching switch 4 having such a configuration will be explained.

When the inching switch 4 is not operated, the elastic force of the coil spring 7 causes the protrusion 5a of the switch cover 5 to move against the display case 2, as shown in FIG.
The other end of the opening 2a (the right end in the figure) is pressed against the other end (right end in the figure). In this state, the switch cover 5 is attached to the sliding guide portion 2.
It is not possible to descend due to b and 2c.

Next time you operate the inching switch 4,
As shown in the figure, move the protrusion 5a of the switch cover 5 in the direction of the arrow, and when the protrusion 5a comes into contact with one end of the opening 2a (the left end in the figure), press this protrusion 5a as shown in Fig. 4. Lower it. Since the sliding parts 5b and 5c of the switch cover 5 come off the sliding guide parts 2b and 2c, the switch cover 5 can be lowered, and when lowered, the switch pressing part 5d presses down the switch button 4a of the inching switch 4. , the switch is turned on. In this state, the spring 7 is compressed by the sliding of the switch cover 5 and the lowering of the rotating shaft 6.

Next, when the protrusion 5a is released, the switch cover 5 rises to the position shown in FIG.
b, 2c and automatically returns to the position shown in FIG.

In addition, in the above example, the inching switch is installed inside the display case 2 through which the selector lever 1 passes, but the inching switch of the present invention is not limited to this, and can be installed in other places such as the instrument panel of the driver's seat. may be provided.

[Effects of the invention] As described above, according to the invention, the inching switch will not turn on unless the switch cover is pushed down after sliding, so the driver will not be able to turn on the inching switch unconsciously. This prevents erroneous operations. Furthermore, since the switch cover and the inching switch are integrally formed, it has the effect of making the switch operation much easier.
