BACKGROUND OF THE INVENTION
The present invention is a vehicle automatic vehicle having a lock pin that rotatably holds a shift lever and that can be slid by a pressing operation of a push knob formed on the distal end side of the shift lever and moves with the shift lever. The present invention relates to a speed change operation device.
[0002]
[Prior art]
An automatic shift operation device for operating an automatic transmission provided in a vehicle usually has a shift lever for a driver to perform a shift operation, and by rotating the shift lever to a desired position, The automatic transmission can be arbitrarily operated. For example, the shift lever is configured to rotate between a parking position (P), a reverse position (R), a drive position (D), and a second speed position (2).
[0003]
Conventionally, such a shift lever is rotatably held by an integral bracket, and an automatic transmission operating device is attached to a vehicle by attaching a mounting bracket to the bracket and fixing the bracket to the vehicle body. On the other hand, a push knob that can be pushed by the driver is formed on the tip side of the shift lever. If the push knob is not pushed, the shift lever moves from the parking position (P) to the reverse position (R) (drive). The second speed position (2) is not rotated from the position (D).
[0004]
For example, as disclosed in Patent Document 1, the shift lever is provided with a lock pin that slides in conjunction with the pressing operation of the push knob, and the lock pin is moved downward by pressing the push knob. If it is not slid, there is an erroneous operation prevention window portion formed with a portion that interferes with the lock pin and restricts the rotation of the shift lever, and a portion that allows the shift lever to rotate without pressing the push knob. It is provided on the bracket.
[0005]
Further, as disclosed in the same document, when the shift lever is in the parking position, the bracket engages with a part of the shift lever and restricts the pivoting operation or disengages the restriction. In order to cancel this, a parking lock means having a solenoid or the like and a forcible release means for forcibly releasing the restriction by the parking lock means are provided.

[Problems to be solved by the invention]
However, the above-described conventional automatic speed change operation device has the following problems because the erroneous operation preventing window, the parking lock means, and the forced release means are formed in the integrated bracket. That is, depending on the type of vehicle to which the automatic speed change operation device is attached, the rotation angle and range of the shift lever and the number of ranges (for example, “P”, “R”, “D”, “2” as described above) In the case of other ranges such as “1”, etc.), it is necessary to change the shape of the erroneous operation prevention window portion accordingly. On the other hand, the parking lock means and the forced release means depend on the rotation angle of the shift lever, etc. There is no need to change the mounting position and angle.
[0008]
However, since the erroneous operation prevention window, the parking lock means and the forcible release means are formed in an integral bracket, the entire bracket is provided for each vehicle model to which an automatic transmission operating device having a different rotation angle of the shift lever is attached. It was necessary to change. Therefore, it is difficult to divert one bracket to an automatic transmission operation device having a different rotation angle and the like, and it is necessary to prepare each bracket, resulting in a problem that manufacturing costs deteriorate.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The vehicle automatic shift operating device according to the present embodiment is for performing a shift operation of an automatic transmission (automatic transmission) included in the vehicle. As shown in FIGS. 1 to 5, a shift lever (select lever) ) 1, a cover member (escussion) 3, a first bracket 8, and a second bracket 9.
[0015]
The shift lever 1 is configured to be gripped by the driver at the distal end side thereof, and is rotatable with respect to the cover member 3, the first bracket 8 and the second bracket 9. In other words, the shift lever 1 is inserted and assembled into a rotation slot 3a formed in the cover member 3 as shown in FIG. 5, and the parking position (P), reverse position (R), drive position (D) and It rotates between the 2nd speed position (2) and performs a desired speed change operation on an automatic transmission (not shown).
[0016]
As shown in FIG. 4, a push knob 1a that can be pressed by the driver is formed on the distal end side of the shift lever 1, and in the longitudinal direction of the shift lever 1 by the pressing operation of the push knob 1a. The extending rod 6 is configured to slide downward, and the spring 7 disposed at the base end of the rod 6 constantly urges the rod 6 upward. When released, the rod 6 returns upward.
[0017]
As shown in the figure, the lock pin 2 extends substantially perpendicular to the longitudinal direction of the rod 6, and the lock pin 2 moves up and down along with the slide of the rod 6 within the shift lever 1. It is configured to slide in the direction. That is, as shown in FIG. 8, a pin insertion hole 1b extending in the vertical direction is formed on the rotation base end side (lower side in the figure) of the shift lever 1, and the lock pin 2 is a pin insertion hole. It slides up and down with the rod 6 along 1b and rotates with the shift lever 1.
[0018]
As shown in FIGS. 1 and 8, the first bracket 8 is attached to one side surface (right side surface in FIG. 2) substantially parallel to the rotation direction of the shift lever 1. Three bolt holes 8a to 8c are formed. The erroneous operation prevention window 10 is formed at a position where one end (the left end in FIG. 4) of the lock pin 2 is inserted, and has a shape that restricts or allows the movement of the lock pin 2. In addition, the code | symbol 16 in FIG. 8 has shown the cushion material fixed to the upper edge part of the misoperation prevention window part 10. FIG.
[0019]
Specifically, the erroneous operation preventing window 10 has a shape as shown in FIG. 9, and when the lock pin 2 is in the upper position (the push knob 1a is not pressed), the shift lever When rotating 1 from the parking position (P) to the reverse position (R), a portion that contacts the lock pin 2 is formed, and the rotation of the shift lever 1 can be restricted. .
[0020]
That is, in order to perform a driver's conscious operation, the push knob 1a is pressed to move the lock pin 2 downward, so that the lock pin 2 does not come into contact with the erroneous operation prevention window 10, thereby shifting the shift lever. 1 is configured to allow rotation from the parking position (P) to the reverse position (R). From the same viewpoint, the shift lever 1 is rotated from the reverse position (R) to the parking position (P), from the neutral position (N) to the reverse position (R), and from the drive position (D) to the second speed position (2). Also when moving, it is necessary to push the push knob 1a.
[0021]
On the other hand, as shown in FIGS. 3 and 8, the second bracket 9 is attached to the other side surface (the left side surface in FIG. 2) substantially parallel to the rotation direction of the shift lever 1, and is attached to the outer side surface thereof. Are provided with a solenoid 11 and a regulating member 12 as a parking lock means, and a forcible releasing means 13. Note that an opening 15 is formed in the second bracket 9 at a position where the other end (right end in FIG. 4) of the lock pin 2 is inserted. The opening 15 has a shape that allows the operation of the lock pin 2 ( (Substantially rectangular shape).
[0022]
The parking lock means comprising the solenoid 11 and the regulating member 12 regulates or cancels the rotation of the shift lever 1 when the shift lever 1 is in the parking position (P) from the viewpoint of preventing an unexpected sudden start. For example, as shown in FIG. 10, a restriction member 12 is connected to an operation portion 11 a that expands and contracts by the operation of the solenoid 11. And in the state which the operation part 11a of the solenoid 11 extended, as shown in the figure, even if the front end surface 12a of the regulating member 12 abuts against the other end of the lock pin 2 and the push knob 1a is pressed, parking is performed. The lock pin 2 in the shift lever 1 at the position (P) is prevented from sliding downward.
[0023]
Further, when an electric signal is transmitted from the vehicle side to the solenoid 11 by recognizing that the driver has stepped on the brake pedal by a sensor or the like, the operation portion 11a of the solenoid 11 contracts. It rotates around the rotating shaft 12b. Accordingly, the front end surface 12a of the restricting member 12 also moves, and if the push knob 1a is pressed, the lock pin 2 can be slid downward, and the shift lever 1 is rotated from the parking position (P) to the reverse position (R). Can be allowed to move.
[0024]
By the way, when an electrical failure occurs in the vehicle, the operation unit 11a may not operate. Therefore, the second bracket 9 is provided with a forcible release means 13 that forcibly rotates the restriction member 12 and releases the restriction by the parking lock means regardless of the drive of the solenoid 11.
[0025]
As shown in the figure, the forcible release means 13 can swing about a shaft 13a, and has an operation surface 13b at one end and an action surface 13c at the other end. Then, when the lid 4 (see FIG. 5) formed on the cover member 3 is removed and the key K is inserted from the insertion hole 5 as shown in FIG. 3, the tip of the key K presses the operation surface 13b, The forcible release means 13 swings about the shaft 13a. By such swinging, the action surface 13c of the forcible release means 13 presses the protruding portion 12c formed on the operation portion 11a side, so that the regulating member 12 is moved in the same direction as when the operation portion 11a of the solenoid 11 contracts. It can be rotated and the restriction by the parking lock means can be released.
[0026]
Further, as shown in FIG. 7, three connecting members 9 a to 9 c each formed in a bar shape are extended from the inner side surface of the second bracket 9, and in the vicinity of the tips of the connecting members 9 a to 9 c. The male screw part is formed in. Moreover, each connection member 9a-9c is formed in the position corresponding to the bolt holes 8a-8c formed in the 1st bracket 8, and as shown in FIG. The first bracket 8 and the second bracket 9 are inserted by inserting the connecting members 9a to 9c through the bolt holes 8a to 8c and screwing the nuts Na to Nc to the male screw portions of the connecting members 9a to 9c. Thus, the rotation base end side of the shift lever 1 is sandwiched.
[0027]
Here, the connecting member 9c, which is one of the three connecting members 9a to 9c, is inserted into the rotation center hole 14 formed on the rotation base end side of the shift lever 1, thereby shifting the shift member 9c. The rotation axis of the lever 1 is formed. Thus, by using one of the connecting members as the rotation shaft of the shift lever 1, the number of parts can be reduced and the assemblability can be improved as compared with the case where a separate rotation shaft is provided.
[0028]
Moreover, as shown in FIG.4 and FIG.8, as for the 1st bracket 8 and the 2nd bracket 9, these lower parts are each bend-formed by the outside, respectively, and it is substantially L-shaped as a whole, and each bending part is A and B are configured to be fixed to the vehicle body. Accordingly, a base member or the like for fixing individual brackets can be eliminated, the number of parts can be reduced, and the manufacturing cost can be reduced. It is preferable that a bolt hole is formed in each of the bent portions A and B, and the bolt is inserted into the bolt hole and fixed to the vehicle body.
[0029]
According to the above-described automatic transmission operation device for a vehicle, the first bracket 8 in which the erroneous operation preventing window 10 is formed on one side surface on the rotation base end side of the shift lever 1, and the parking lock means (solenoid) on the other side surface. 11 and the restricting member 12) and the second bracket 9 provided with the forcible releasing means 13 are provided, respectively, and the following effects can be obtained.
[0030]
Since only the first bracket 8 needs to be changed with respect to other automatic transmission operation devices having different rotation angles, rotation ranges, number of ranges, etc. of the shift lever, the second bracket 9 can be used as it is. Deployment of the device to other models is relatively easy, and deterioration of manufacturing costs can be suppressed. That is, it is mainly the erroneous operation prevention window that needs to be changed according to the shift lever turning angle or the like. The first bracket 8 formed with such an erroneous operation prevention window is formed according to the model of the automatic transmission operation device. If it is replaced, the second bracket 9 that does not depend much on the difference in model can be used as it is.
[0031]
Furthermore, according to the automatic speed change operation device as in this configuration, since it is possible to assemble from one side (first bracket 8 or second bracket 9) in order, it is possible to improve the assemblability. That is, in the case where the conventional bracket is integrated, there is a limit to the direction in which the shift lever or the like is assembled (specifically, assembly from the direction perpendicular to the rotation direction of the shift lever is necessary). On the other hand, according to this embodiment, since it can be assembled from one side, there is no limitation on the assembly direction of the shift lever or the like interposed between the brackets, and the assembly is improved.
[0032]
Although the present embodiment has been described above, the present invention is not limited to this. For example, as shown in FIGS. 11 and 12, the lower portion of the first bracket 8 ′ in which the erroneous operation prevention window portion 10 is formed is on the inner side and the outer side. The bent portions C and D extending inwardly and outwardly may be fixed to the vehicle body while being formed into a bent shape and having an inverted T-shape as a whole.
[0033]
According to such another embodiment, as in the case where the lower part of each bracket is L-shaped as described above, a base member or the like for fixing each bracket can be eliminated, and the number of parts can be reduced. Thus, the manufacturing cost can be reduced, and it is not necessary to bend the lower portion of the second bracket 9 ′. Instead of such an embodiment, the lower part of the second bracket provided with the parking lock means and the forcible release means is bent inwardly and outwardly to have an inverted T-shape as a whole, and inside and outside these parts. A bent portion extending to the vehicle body may be fixed to the vehicle body.
[0034]
【The invention's effect】
According to the first aspect of the present invention, the first bracket on which one of the side surfaces of the shift lever on the rotation base end side is provided with an erroneous operation prevention window, and the other side surface is provided with the parking lock means and the forcible release means. Since the second brackets are respectively disposed, it is sufficient to change only the first bracket with respect to other automatic transmission operation devices having different rotation angles of the shift lever, and the second bracket can be used as it is. Deployment of the automatic transmission operation device to other models is relatively easy, and deterioration of manufacturing costs can be suppressed.
[0035]
According to the second aspect of the present invention, the shift lever includes the plurality of connecting members that connect the first bracket and the second bracket via the rotation base end side of the shift lever, and one of the connecting members is the shift lever. Since the rotating shaft is formed, the number of parts can be reduced and the assembling property can be improved.
[0036]
According to the invention of claim 3, the first bracket and the second bracket are formed such that the lower portions thereof are bent outward, respectively, so as to be substantially L-shaped as a whole, and the respective bent portions are fixed to the vehicle body. Since it is comprised so that the base member etc. for fixing each bracket can be made unnecessary, a number of parts can be reduced and manufacturing cost can be reduced.
[0037]
According to the invention of claim 4, one lower portion of the first bracket or the second bracket is bent inwardly and outwardly, and is formed into an inverted T-shape as a whole, and the bent portion extends inwardly and outwardly. Since the base is fixed to the vehicle body, the base member for fixing the individual brackets can be eliminated as in the invention of claim 3, the number of parts can be reduced, and the manufacturing cost can be reduced.
