Abstract

PURPOSE:To enable switch-over to 1st and 2nd forward speed to be made only when in a drive range, and also enable switch-over to a parking range to be made only when in a neutral range by covering a switch box while being interlocked with shift lever. CONSTITUTION:A switch-over switch 15 to a parking range P is interposed at the upper section of a switch box 7, and switch-over switches 18 and 21 to 2nd forward speed S and 1st forward speed F are also interposed at the lower end of the box. One end section 25 of a cover 9 is rotatably 23 supported onto an instrument panel, and is concurrently supported rotatably onto a bar 27 projecting outward from a shift lever 1. The other end section 29 is controlled to be rotated in such a way that it covers only the switch-over switch 15 to the parking range P when the shift lever 1 is in a drive range D, and it is also controlled to cover the switch-over switches 19 and 21 to the 2nd and 1st forward speed ranges when the shift lever 1 is in a neutral range N. Moreover, it is controlled to cover the whole of the respective switch-over switches when the shift lever 1 is in a reverse speed range R.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shift device for an automatic transmission used in an automobile.

[Prior Art and Problems to be Solved by the Invention] A conventional shift device for an automatic transmission used, for example, in the floor of an automobile, is disclosed in, for example, Japanese Utility Model Application No. 131425/1983.

However, according to this conventional technology, since the system uses a button switch to switch between parking range, reverse range, neutral range, drive range, and 2nd and 1st speed ranges, it is possible to accidentally switch to drive range while driving at high speed. For example, there is a risk that the parking range switch may be pressed. Furthermore, there is a risk that, for example, the 2nd or 1st gear range switch may be pressed by mistake while the vehicle is moving backwards in the reverse range, and an improvement is desired.

Therefore, according to the present invention, in view of such conventional problems, two
When switching to the 1st and 1st speed ranges, switching to the 2nd and 1st ranges is possible only when the vehicle is in the drive range, and when switching to the parking range, it is possible to switch to the parking range only when the vehicle is in the neutral range. The aim is to make it possible.

[Means to solve the problem]

In order to achieve such an object, the present invention provides a shift device for an automatic transmission that includes a shift lever that is pivotally supported on the vehicle body and is capable of switching only a drive range, a neutral range, and a reverse range, and a switch for switching to a parking range at the top. A switch box in which a switch is arranged and a switch for switching to 2nd speed and 1st speed is arranged at the bottom,
a cover that is rotatably supported on the vehicle body, one end of which is supported by the shift lever, and the other end of which is slidable on the front side of the switch box; and a cover that gives priority to the operation of the switch box over the operation of the shift lever. The priority system is such that when the shift lever is in the drive range, the switch for switching to 2nd gear or 1st gear is exposed, and the switch for switching to the parking range is covered, and when the shift lever is in the neutral range, the switch for switching to the parking range is exposed. When the shift lever is in the range, the changeover switch to the parking range is exposed and the changeover switches to the 2nd and 1st speeds are covered, and when the shift lever is in the reverse range, the switches to the 2nd and 1st speeds and the parking range are covered. The priority system is formed to cover all of the changeover switches, and the priority system changes the range of the automatic transmission to drive when the changeover switch to 2nd speed or 1st speed is pressed when the shift lever is in the drive range. When switching from range to 2nd speed or 1st speed range and pressing the switch to switch to parking range when the shift lever is in neutral range, the range of the automatic transmission is changed from neutral range to parking range. It is characterized by:

[For production]

Since the present invention has such a configuration, its operation will be explained next.

When the shift lever is rotated to the drive range,
The cover rotates with the movement of the shift lever, shifting between 2nd and 1st gears.
Only the continuous selection switch is exposed, and the 2nd and 1st speed selection switches can be operated.

When the shift lever is rotated to the neutral range, the cover rotates due to the movement of the shift lever, exposing only the parking range switch, allowing the parking range switch to be operated.

Of course, it goes without saying that when the shift lever is rotated from drive range to neutral range to reverse range, the gear of the automatic transmission changes to each range.

Therefore, while the shift lever is in the drive range,
By pressing either the 2nd speed or 1st gear selector switch, the priority system allows you to switch between 2nd speed or 1st speed range.

At the same time, unless the shift lever is in the drive range, the switch for 2nd and 1st gear cannot be operated.
Even if you make a mistake, you will not be able to switch to the 2nd or 1st speed range.

Additionally, if the shift lever is in the neutral range and you press the switch to switch to the parking range, the priority system will switch the range to the parking range.

At the same time, unless the shift lever is in the neutral range, the parking changeover switch cannot be operated, so even if the shift lever is not in the neutral range, the changeover to the parking range cannot be performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of an embodiment of the present invention will be described below with reference to the drawings.

1 and 2 are diagrams showing one embodiment of the present invention, and reference numeral 1 designates a shift lever 5 that is pivotally supported on an instrument panel 3, which is a vehicle body, so as to be rotatable up and down. Reference numeral 7 is a switch box fixed to the instrument panel 3. Reference numeral 9 is a cover.

The shift lever 1 is movable up and down through a long hole 11 formed on the surface of the instrument panel 3, and has an operation knob 13 on a portion protruding from the surface of the instrument panel 3. On the rear side 1a of the shift lever 1, when the operating knob 13 of the shift lever 1 is operated downward, the range of the automatic transmission (not shown) is switched to drive range D, and the operating knob 13 of the shift lever 1 is set to neutral. When the automatic transmission (not shown) is operated, the range of the automatic transmission (not shown) is switched to the neutral range N, and the operation knob 1 of the shift lever 1 is pressed.
3 is connected in such a way that the range of an automatic transmission (not shown) is switched to reverse range R when the switch 3 is operated upward.

The switch box 7 is arranged on the surface of the instrument panel 3, and has a changeover switch 15 for parking range P on the top and 2nd speed S and 1st gear on the bottom.
Switches 19 and 21 for switching to speed F, respectively, are provided.

The cover 9 has one end 25 and the other end 29 formed in an abbreviated shape in plan view, and the one end 25 is rotatably supported by a shaft 23 on the instrument panel 3 and is located on the side of the shift lever 1. When the shift lever 1 is in the drive range D, the other end 29 covers the changeover switch 15 to the parking range P as shown in FIG. Changeover switch 19, 2 to 2nd speed range S and 1st speed range F
When the shift lever 1 is in the neutral range N, the switch 1 is controlled to rotate downward so that the shift lever 1 is exposed, and when the shift lever 1 is in the neutral range N, the changeover switch 1 is switched to the 2nd speed range S and the 1st speed range F, respectively.
9, 21 and the parking range P from the opening 17.
When the shift lever 1 is in the reverse range R, the shift lever 1 is rotated to the neutral position so that the changeover switch 15 to
, 2nd speed range S changeover switches 15 , 21 ,
19 are assembled so that they are all covered.

The relationship between the shift lever 1 and each switch 15, 19, 21 of the switch box 7 is controlled by a priority system. The priority system is such that when the shift lever 1 is in the drive range D, when the switches 19 and 21 to switch to 2nd gear S or 1st gear F are pressed, the range of the automatic transmission (not shown) is changed to the drive range with the shift lever 1. Despite being in range D, drive range D
, the shift lever 1 is switched preferentially to the 2nd gear range S or the 1st gear range F, and the shift lever 1 is shifted to the neutral range N.
When the switching switch 15 to the parking range P is pressed when the shift lever 1 is in the neutral range N, the range of the automatic transmission (not shown) is switched preferentially from the neutral range N to the parking range P even though the shift lever 1 is in the neutral range N. controlled to change.

With this configuration, when the shift lever 1 is rotated to the neutral range N, for example, the changeover switch 15 for the parking range P is exposed from the opening 17 of the cover 9, but the changeover switch 15 for the parking range P is exposed from the opening 17 of the cover 9; Since the changeover switches 19 and 21 for F are covered by the other end 29 of the cover 9, it is impossible to operate the changeover switches 19 and 21 for 2nd and 1st speeds. This prevents problems such as the vehicle suddenly starting to move due to a child accidentally switching to 2nd gear or 1st gear S-F while the vehicle is stopped by pressing the changeover switch 15. This will further improve safety.

Then, when the shift lever 1 is rotated in the same manner, for example, to the drive range D, the other end 29 of the cover 9 rotates as the shift lever 1 rotates, and the changeover switches 19 and 21 for 2nd speed S and 1st speed F are rotated. is exposed through the opening 17 of the cover 9, and only the switches 19 and 21 can be operated.Since the changeover switch 15 for the parking range P is covered by the other end 29 of the cover 9, the parking range P Since it is impossible to operate the changeover switch 15 for parking range P, for example, while the vehicle is climbing a slope after pressing the changeover switch 19 to 2nd gear range S, a child or the like may accidentally press the changeover switch 19 to parking range P. 15
This will prevent problems such as the vehicle suddenly stopping when the button is pressed, further increasing safety.

Similarly, when the shift lever 1 is rotated to, for example, the reverse range R, the other end 29 of the cover 9 rotates as the shift lever 1 rotates, and the parking range P, 2
Selector switch 15 for speed range S and 1st speed range F,
Since the switches 19 and 21 are all covered by the other end 29 of the cover 9, it is impossible to operate the changeover switches 15, 19, and 21 for the parking range P, etc. This further increases safety by preventing problems such as the vehicle suddenly stopping while reversing or shifting into forward gear.

Note that numerals 31, 33, and 35 are symbols written on the surface of the instrument panel 3 to indicate that the shift lever 1 is in the reverse range R1, neutral range N, and drive range D. Further, the reference numeral 37 is a steering wheel.

〔effect〕

As explained above, according to the present invention, the shift device for the automatic transmission includes a shift lever that is pivotally supported on the vehicle body and can switch only the drive range, neutral range, and reverse range, and a shift lever on the top that is connected to the parking range. A changeover switch is arranged and the 2nd speed and 1st speed are located at the bottom.
a switch box in which a changeover switch for each speed is disposed; a cover rotatably supported on the vehicle body, one end of which is supported by the shift lever, and the other end of which is slidable on the front side of the switch box; It has a priority system that gives priority to the operation of the switch box over the operation of the shift lever, and the cover exposes the changeover switch to the second gear or the first gear when the shift lever is in the drive range, and also exposes the changeover switch to the second gear or the first gear when the shift lever is in the drive range. When the shift lever is in the neutral range, the parking range switch is exposed and the 2nd and 1st gear switches are covered, and the shift lever is in the reverse range. When the shift lever is in the drive range, the priority system is formed to cover all of the switches for switching to 2nd gear, 1st gear, and parking range, and the priority system covers each of the 2nd gear and 1st gear switches when the shift lever is in the drive range. When you press the switch to switch to the parking range, the range of the automatic transmission changes from the drive range to the 2nd or 1st range.If you press the switch to switch to the parking range when the shift lever is in the neutral range, the range of the automatic transmission changes from the drive range to the 2nd or 1st range. Since the range is switched from the neutral range to the parking range, when the shift lever is rotated to the drive range, the cover is rotated by the movement of the shift lever, and the range is changed to 2nd gear.
Only the 1st gear selector switch is exposed and the 2nd and 1st gear selector switches can be operated. Also, when the shift lever is rotated to the neutral range, the cover rotates due to the movement of the shift lever and the switch is set to the parking range. Only the changeover switch for 2nd gear, 1st gear, and parking range can be operated when the shift lever is in the reverse range. Therefore, when switching to the 2nd and 1st gear ranges, it is possible to switch to the 2nd and 1st gear ranges only when the vehicle is in the drive range, and when switching to the parking range, it is possible to switch to the parking range only when the vehicle is in the neutral range. This is an invention that has a practical effect and is designed to further improve safety.
