Description

Shift device

The present invention relates to a shift device for a vehicle.

Conventionally, a shift device for a vehicle for switching the gear range of an automatic transmission is well known.
The shift device of Patent Document 1 includes a P switch for setting the gear range to the parking range, an R switch for setting the reverse range, an N switch for setting the neutral range, and a D switch for setting the forward range. Is provided. The P switch, N switch, and D switch are juxtaposed, and are push switches that are pushed in a first direction that intersects the juxtaposed direction. The R switch is a push switch that is pushed in the second direction along the parallel direction. Note that the tip of the R switch is covered with a cover that is juxtaposed with the P switch, the N switch, and the D switch. When the cover is pushed in the first direction, the cover rotates around the rotation shaft provided on the N switch side and comes into contact with the tip of the R switch. After the contact between the cover and the tip of the R switch, the R switch can be pushed in the second direction. That is, in the shift device, in order to push the R switch in the second direction, it is necessary to push the cover in the first direction.

JP 2014-83974 A

In the switch device of Patent Document 1, since the cover of the R switch is pushed in the same first direction as the P switch, N switch, and D switch, the driver only pushes the cover. There is a risk of erroneously recognizing that the R switch has been pushed, leading to an erroneous operation of the shift device.

The present invention is to provide a shift device in which erroneous operations are suppressed.

In one aspect, the shift device includes a first changeover switch that is operated toward the first direction and is allowed to be operated in a second direction that intersects the first direction. By detecting the displacement of the first changeover switch in the second direction in the detection unit, the shift range of the transmission is changed to the gear range corresponding to the first changeover switch.

According to this configuration, the transmission cannot be switched to the gear range corresponding to the first changeover switch unless the first changeover switch itself is operated in the first direction and the second direction. That is, since it is necessary to operate the first changeover switch in two stages, erroneous operation of the first changeover switch is suppressed.

In the above configuration, it is preferable that a second changeover switch that is allowed to operate only in the second direction is provided, the first changeover switch is one, and the corresponding gear range is a reverse range.

According to this configuration, since only the first changeover switch for switching to the reverse range can be operated in the first direction, it is easy to differentiate between the first changeover switch and the second changeover switch through the operation. Thereby, erroneous operation of the first changeover switch is suppressed.

In the above configuration, it is preferable that one of the operation in the first direction and the operation in the second direction is a rotation operation and the other is a linear operation.
According to this configuration, it is easy to determine that the first changeover switch has been operated from the difference in operation. In addition, it is easy to determine that the second selector switch has been operated.

In the above configuration, it is preferable that a second changeover switch that is allowed to be operated only in a third direction different from any of the first direction and the second direction is provided.
According to this configuration, since the operation direction of the first changeover switch operated in two steps is different from the operation direction of the second changeover switch operated in one step, the first changeover switch and the second changeover switch In either case, it is difficult for erroneous operations to occur.
The said structure WHEREIN: It is preferable that the said shift apparatus is further provided with the lock protrusion which controls operation to the said 2nd direction of a said 1st changeover switch when the said 1st changeover switch exists in an original position. In this case, when the operation of the first changeover switch in the first direction is performed, the first changeover switch is opposed to the lock protrusion, thereby causing the first changeover switch in the second direction. It is preferable to include a lock release groove that allows operation of the changeover switch.
According to this configuration, a two-step operation of the first changeover switch can be realized by a simple lock mechanism using a combination of a protrusion and a groove.

Hereinafter, an embodiment of a shift device will be described with reference to the drawings.
As shown in FIG. 1, the shift device 1 includes a housing 2 and a plurality of operation units 3 that are pushed. The shift device 1 switches the gear range of a transmission (automatic transmission) 4 (see FIG. 3) mounted on a vehicle when the operation unit 3 is operated. It is arranged around the console, the instrument panel, and these components.

As shown in FIG. 2, the housing 2 includes left and right divided

bodies

21 and 22, a rear divided body 23, and a base plate 24, and the left and right divided

bodies

21 and 22 extend the left and right sides of the base plate 24. 23 respectively cover the rear side of the base plate 24. For this reason, as shown in FIG. 1, the housing 2 has a front opening 25.

As shown in FIG. 2, a recess 21 a that faces the front opening 25 is provided in the upper part of the left divided body 21.
The shift device 1 includes a substrate 5, a contact rubber 6, and a contact member 7 between the rear divided body 23 and the base plate 24.

As shown in FIG. 3, the substrate 5 has fixed

contacts

5 a, 5 b, 5 c arranged in the vertical direction so as to be exposed on the front surface, and is fixed to the front surface of the rear divided body 23. The substrate 5 is electrically connected to a shift ECU 8 that switches the gear range of the transmission 4. The shift ECU 8 outputs a shift signal for switching the gear range to the transmission 4 based on the contact state between the fixed

contacts

5a, 5b, and 5c and corresponding movable contacts described later. More specifically, the shift ECU 8 switches the shift signal for switching to the reverse range when the fixed contact 5a and the corresponding movable contact come into contact with each other, and switches the shift signal to the neutral range when the fixed contact 5b and the corresponding movable contact come into contact with each other. A shift signal for switching to the drive range is output when the shift signal comes into contact with the fixed contact 5c and the corresponding movable contact. As a result, the gear range of the transmission 4 is switched. As shown in FIG. 3, the shift ECU 8 may be provided outside the substrate 5 or may be provided on the substrate 5. The fixed contact 5a corresponds to a switch detection unit.

Contact rubber 6 covers the front surface of substrate 5. The contact rubber 6 has

click domes

6a, 6b, 6c arranged in a vertical direction so as to protrude forward, and these

click domes

6a, 6b, 6c have corresponding fixed

contacts

5a, 5b, 5c respectively. Covering. A metal material (not shown) for closing the internal circuit of the substrate 5 when attached to the corresponding fixed

contacts

5a, 5b, 5c is attached to the rear surfaces of the

click domes

6a, 6b, 6c. The metal material corresponds to a movable contact.

Contact member 7 is a general term for

contact members

7a, 7b, and 7c arranged in parallel in the vertical direction. The contact member 7 extends in the front-rear direction. The

contact members

7a, 7b, and 7c are provided so as to correspond to the

click domes

6a, 6b, and 6c, respectively, and are inserted in through

holes

27a, 27b, and 27c that are arranged in parallel in the vertical direction on the base plate 24 and penetrate in the front-rear direction. ing. The tip portions of the

contact members

7a, 7b, and 7c are positioned in front of the base plate 24, respectively.

As shown in FIG. 1, the shift device 1 includes, as an operation unit 3, an R switch 31 for switching the transmission 4 to the reverse range, an N switch 32 for switching the transmission 4 to the neutral range, and the transmission 4. A D switch 33 for switching to the drive range is provided. The R switch 31, the N switch 32, and the D switch 33 are juxtaposed in the vertical direction in a state of being exposed from the front opening 25 provided in the housing 2. In the present embodiment, the R switch 31 is an example of a first changeover switch, and each of the N switch 32 and the D switch 33 is an example of a second changeover switch.

2 and 3, the R switch 31 has a support piece 31a extending downward from the rear end portion. The D switch 33 has a support piece 33a extending upward from the rear end. The tip portions of the

support pieces

31a and 33a are rotatably supported by support portions 28 provided on the base plate 24, respectively. That is, the R switch 31 and the D switch 33 rotate around the tip portions of the

support pieces

31a and 33a, respectively.

In addition, as shown in FIG. 2, the clearance C is set between the support piece 31a and the support piece 33a in the left-right direction. As shown in FIG. 7, the R switch 31 is allowed to be displaced in the left-right direction by the previous clearance C and the recess 21a. A return spring 34 in an elastically compressed state is interposed between the left support piece 31a and the support piece 33a. The R switch 31 is always urged rightward by the return spring 34. The displacement of the R switch 31 in the left-right direction is restricted by the left and right divided

bodies

21, 22, respectively. 7, the position of the R switch 31 indicated by a solid line is defined as an original position, and the position of the R switch 31 indicated by a two-dot chain line in FIG. 7 is defined as an intermediate position.

Further, as shown in FIGS. 8A, 8B, 9A, and 9B, the lock release groove 37 is recessed in the rear end surface 36 of the R switch 31. It is installed. When the R switch 31 is in the original position (the position indicated by the solid line in FIG. 7), the lock release groove 37 does not face the lock protrusion 26 protruding from the front surface of the base plate 24, and the R switch 31 is in the middle. When in the position (the position indicated by the two-dot chain line in FIG. 7), it faces the lock protrusion 26. The inner diameter of the lock release groove 37 is set to be slightly larger than the outer diameter of the lock protrusion 26, and the lock protrusion 26 is allowed to enter the lock release groove 37. When the R switch 31 is in the original position, the rear end face 36 of the R switch 31 and the lock protrusion 26 face each other. In other words, the R switch 31 at the original position is restricted from moving backward, and the R switch 31 at the intermediate position is allowed to move backward.

As shown in FIGS. 2 and 3, the N switch 32 is supported by the base plate 24 so as to be displaceable in the front-rear direction while being sandwiched between the R switch 31 and the D switch 33 in the vertical direction.

3 to 6, the R switch 31, the N switch 32, and the D switch 33 are in contact with the front ends of the

contact members

7a, 7b, and 7c at the respective rear ends. Accordingly, the R switch 31, the N switch 32, and the D switch 33 can be pushed backward by the amount of elastic deformation of the

click domes

6a, 6b, and 6c via the

contact members

7a, 7b, and 7c, respectively. It is said that.

Next, the movement when each switch is operated will be described.
The N switch 32 reaches the position (push position) shown in FIG. 5 by being pushed backward from the position (original position) shown in FIG. 3 against the elastic force of the click dome 6b. When the operation is canceled, the N switch 32 returns to the original position along with the elastic return of the click dome 6b.

The D switch 33 reaches the position (push position) shown in FIG. 6 by being pushed backward from the position (original position) shown in FIG. 3 against the elastic force of the click dome 6c. When the operation is canceled, the D switch 33 returns to the original position along with the elastic return of the click dome 6c.

The R switch moves from the position indicated by the solid line in FIG. 7 (original position) (see FIGS. 8A and 9A) to the left against the elastic force of the return spring 34 (see FIG. 2). As a result of the sliding operation, the position (intermediate position) indicated by a two-dot chain line in FIG. 7 (see FIGS. 8B and 9B) is reached. Furthermore, the R switch 31 reaches the position (push position) shown in FIG. 4 by being pushed backward from the state of being located at the intermediate position against the elastic force of the click dome 6a. When the operation is canceled, the R switch 31 returns to the intermediate position with the elastic return of the click dome 6a, and then returns to the original position with the elastic return of the return spring 34.

Next, the operation and effects of the shift device 1 will be described.
As shown in FIGS. 8 (a) and 9 (a), the R switch 31 at the original position is restricted from being pushed backward, and as shown in FIGS. 8 (b) and 9 (b) The R switch 31 at the position is allowed to push backward. Therefore, in order to switch the gear range of the transmission 4 through the R switch 31, the R switch 31 at the original position is slid leftward (corresponding to the first direction) and then rearward (in the second direction). It is necessary to perform a push operation toward the corresponding). That is, since the R switch 31 needs to be operated in two steps, it is unlikely to be erroneously operated. Further, since the R switch 31 is not covered with a cover or the like as in the prior art and is exposed to the outside, it is easy to determine whether or not it has been operated in two steps. For this reason, erroneous operation of the R switch 31 is suppressed.

Also, the N switch 32 and the D switch 33 are only allowed to push backwards corresponding to the second direction. On the other hand, the R switch 31 needs to be pushed backward after a sliding operation to the left corresponding to the first direction. Therefore, it is easy to differentiate the R switch 31 from other switches through operation. Thereby, erroneous operation of the R switch 31 is suppressed.

In addition, you may change the said embodiment as follows.
In the above embodiment, the R switch 31 is a two-step operation by two linear operations, that is, a linear operation in the left-right direction (slide operation) and a linear operation in the front-rear direction (push operation). Is not limited to this.

A case will be described in which the R switch 41 shown in each of FIGS. 10A and 10B and FIGS. 11A and 11B is employed instead of the R switch 31 of the above embodiment. In this example, the R switch 41 corresponds to a first changeover switch. The R switch 41 has an elliptical lock release groove 43 recessed in the rear end face 42. As shown in FIG. 10A, in the state where the R switch 41 is in the original position, the inner diameter dimension of the lock release groove 43 in the left-right direction is smaller than the outer diameter dimension of the lock protrusion 26 and The dimensions are set to be larger than the outer diameter dimension of the lock protrusion 26.

For this reason, by rotating the R switch 41 counterclockwise from the original position shown in FIG. 10A to reach the intermediate position shown in FIG. 10B, the unlocking groove shown in FIG. The state in which the entry of the lock protrusion 26 into the state 43 is restricted is changed to a state in which the entry of the lock protrusion 26 into the lock release groove 43 shown in FIG. Thereby, push operation of R switch 41 is permitted.

As described above, since the R switch 41 requires different two-stage operations of the counterclockwise rotation operation and the backward linear operation (push operation), it is determined whether or not the R switch 41 is pushed. Is easier than the above embodiment. The other switches (N switch 32 and D switch 33) are only push operations. Therefore, it is easy to differentiate the R switch 41 from other switches through operation.

In addition, in the other example, the rotation operation of the R switch 41 may be a clockwise operation.
Further, the two-stage operation is not limited to the above embodiment and the above example.

When the R switch 51 shown in FIGS. 12, 13A, 13B, 14C, 14A, 14B, and 14C is used instead of the R switch 31 of the above embodiment. Will be described. In this example, the R switch 51 corresponds to a first changeover switch. The R switch 51 has a lock release groove 53 that is recessed in the rear end surface 52. As shown in FIG. 14, the lock release groove 53 includes a first release groove 54 and a second release groove 55, and the first and

second release grooves

54 and 55 respectively have inner and

lower surfaces

54 a and 55 a. Are continuously continuous in the left-right direction.

The vertical dimension of the first release groove 54 is set slightly larger than the vertical dimension of the lock protrusion 26.
The vertical dimension of the second release groove 55 is set sufficiently larger than the vertical dimension of the lock protrusion 26.

With this configuration, when the R switch 51 is slid rightward from the original position indicated by the solid line in FIG. 12 to reach the intermediate position indicated by the two-dot chain line in FIG. a) As shown in (b), the lock projection 26 changes from the state in which it enters the first release groove 54 to the state in which the lock projection 26 enters the second release groove 55.

As shown in FIG. 13A, since the vertical dimension of the first release groove 54 is only slightly larger than the vertical dimension of the lock protrusion 26, the inner upper surface 54b of the first release groove 54 and the upper surface of the lock protrusion 26 The distance between is short. For this reason, since the inner upper surface 54b of the first release groove 54 and the upper surface of the lock protrusion 26 are engaged with each other, the R switch 51 cannot be rotated around the rotation shaft provided in the support piece 51a (see FIG. 15). . That is, the R switch 51 cannot be pulled forward.

On the other hand, as shown in FIG. 13B, the vertical dimension of the second release groove 55 is sufficiently larger than the vertical dimension of the lock protrusion 26. For this reason, a sufficient space is secured between the inner upper surface 55 b of the second release groove 55 and the upper surface of the lock protrusion 26. For this reason, as shown in FIG.13 (c), R switch 51 can be pulled to the near side. That is, the R switch 51 can be pulled.

In addition, when adopting the R switch 51 that performs the pulling operation toward the front side in this way, as shown in FIG. 15, the support piece 51a that is longer than the support piece 31a of the above embodiment is adopted. And while supporting the center part of the up-down direction of the support piece 51a rotatably, the contact member 7a, the click dome 6a, and the fixed contact 5a are made to respond | correspond to the front-end | tip part of the said support piece 51a. If comprised in this way, when the R switch 51 is pulled to the near side, the front-end | tip part of the support piece 51a displaces back, Therefore The shift ECU8 can detect that the R switch 51 was operated. Note that the direction pulled toward the front corresponds to the second direction, and the direction in which the N switch 32 and the D switch 33 are pushed backward (see FIGS. 5 and 6) corresponds to the third direction.

When configured as described above, the R switch 51 operated in two steps is different from the direction in which the N switch 32 and the D switch 33 are pushed in any direction. Incorrect operation of the 32 and the D switch 33 is suppressed. Further, erroneous operation of the R switch 51 in an attempt to operate the N switch 32 or the D switch 33 is suppressed.

In the above embodiment, the R switch 31 is a two-stage operation in which a push operation is performed after a slide operation, but may be a two-stage operation in which a slide operation is performed after a push operation. In such a configuration, it is preferable that the N switch 32 and the D switch 33 are also slid.

-In above-mentioned embodiment, although R switch 31, N switch 32, and D switch 33 were arranged in the up-down direction, the parallel arrangement direction is not restricted to the said direction.
In the above embodiment, the shift positions allocated to the R switch 31, N switch 32, and D switch 33 may be changed as appropriate.

In the above embodiment, the switch that requires the two-stage operation is the R switch 31, but another switch may be used. Moreover, the structure which requires a two-step operation may be sufficient as a some switch.

In the above embodiment, the R switch 31, the N switch 32, and the D switch 33 are provided, but the number of switches used for switching the gear range may be changed as appropriate. For example, a P switch for switching the gear range to parking may be provided.
