Technical Field

The present invention relates to a push type shift device.

Background

There is known a push-type shifting device that switches a gear ratio in response to a shift operation input via an operation knob (button) instead of a shift lever. In the push type shifting device, there are cases where: the housing main body has a recess, and an operation knob (hereinafter referred to as a "slide-type operation knob") which is displaceable in a direction different from the vertical direction is provided in the recess.

Disclosure of Invention

Problems to be solved by the invention

However, in the above-described conventional technique, there is a concern that the original operability of the slide-type operation knob may be impaired by foreign matter falling into the recess or the like. For example, if a liquid having a high viscosity enters the recess, the liquid may flow into a space between the slide-type operation knob and the panel and solidify, and the operation knob may be fixed and not be moved. In contrast, simply providing a wall for blocking liquid in the front side of the operation knob creates a gap in the sliding direction between the wall and the knob during the sliding operation of the operation knob, and there is a problem that the operation knob cannot be returned to the initial position if a large solid body such as a snack is sandwiched.

Therefore, in the aspect 1, the present invention aims to improve the possibility that the original operability of the slide-type operation knob can be maintained even if foreign matter falls into the recess or the like.

Means for solving the problems

In an aspect, there is provided a push type shift device including:

a first operation knob of a slide type which is displaceable in a sliding direction between a first position and a second position, the first operation knob being in a direction different from the vertical direction as the sliding direction;

a housing main body having a recess formed on an upper surface thereof and recessed downward, the recess having an opening formed therein and opening in the sliding direction, the opening being provided for the first operation knob;

a contact portion that generates an operation signal based on a displacement of the first operation knob to the second position; and

a slider connected to the first operation knob and supported to be displaceable in the sliding direction with respect to the housing main body,

when the first operation knob is located at the second position, the recess and the first operation knob form a gap in the sliding direction, and the slider includes a communication means for communicating the gap in the vertical direction with a space below the slider.

Effects of the invention

In the aspect 1, according to the present invention, it is possible to improve the possibility that the original operability of the slide-type operation knob can be maintained even if foreign matter falls into the recess or the like.

Detailed Description

Hereinafter, each embodiment will be described in detail with reference to the drawings.

[ example 1]

Fig. 1 is a plan view schematically showing a shifting device 1 of embodiment 1. Fig. 2 is a sectional view briefly showing a section along line a-a of fig. 1. Orthogonal 3-axis X, Y, Z is defined in fig. 1. The Y axis corresponds to a displacement direction (sliding direction) of an operation knob described later. In the mounted state of the shift device 1, the Y axis extends in a substantially horizontal plane, and the Z axis corresponds to the vertical direction. However, in the mounted state of the shift device 1, the Z axis may not be parallel to the gravitational direction.

The shifting device 1 is a push-type shifting device for switching the transmission ratio, and is operated by a user. The gear ratio to be switched is a gear ratio of a transmission (transmission), and the form of the transmission is arbitrary. The gear shift device 1 is mounted on a mobile body having a transmission case, for example, a vehicle, an airplane, or the like. As for the speed change ratio, for example, in a vehicle, the shifting device 1 may be used for shift-by-wire type shifting operation.

The shift device 1 includes a case body 10, operation buttons 2, 3, and 7, and an upper slider 50 (an example of a slider).

The case body 10 is formed of, for example, resin or the like. The housing body 10 is fixed to a moving body. The housing body 10 may be formed of a plurality of parts. The housing body 10 includes a panel member 12 that forms an upper surface of the shifting device 1.

The case body 10 has a recess 120 formed on the upper surface thereof and recessed downward. The concave portion 120 is formed at a position on the negative side in the Y direction with respect to the base surface 122 of the panel member 12 so as to be deeper toward the negative side in the Y direction (an example of a side from the first position toward the second position), as shown in fig. 2, for example. The recess 120 extends in the X direction by a length corresponding to the length of the operation knob 7 in the X direction as shown in fig. 1.

As shown in fig. 2, the recess 120 has a wall 130 rising upward. The wall portion 130 functions as a protection wall against foreign matter as will be described later. The wall 130 stands upward in the Z direction and defines an opening 126 (described later) on the upper side in the Z direction. The wall 130 preferably extends in the X direction so as to cover the entire X direction of the operation knob 7. That is, the relationship between the wall portion 130 and the operation knob 7 shown in fig. 2 (the same applies to the relationship in fig. 3 described later) is preferably realized at an arbitrary position in the X direction of the operation knob 7.

As shown in fig. 2, the case body 10 has an opening 126 that opens in the Y direction at the end on the Y direction negative side in the concave portion 120. In the example shown in fig. 2, the opening 126 is formed by a difference in the vertical direction between the portion 124 of the panel member 12 extending to the Y direction negative side of the recess 120 and the surface of the recess 120. Specifically, the portion 124 of the panel member 12 defines the opening 126 at the lower side, and the wall portion 130 of the recess 120 defines the opening 126 at the upper side. More specifically, opening 126 is formed between end 124a on the Y-direction positive side of portion 124 and end 120a on the Y-direction negative side of recess 120 (end 120a on the Y-direction negative side of wall 130). In addition, it is preferable that the portion 124 extend in a range not overlapping with the recess 120 in a plan view (a view angle viewed in the Z direction) due to an assembling property.

The operation buttons 2, 3, and 7 are members operated by the user. The operation knobs 2 and 3 are members operated obliquely, for example, in the vertical direction or slightly inclined with respect to the vertical direction, and the operation knob 7 (an example of a first operation knob) is a slide-type operation knob and is a member operated in the Y direction. In the example shown in fig. 1, the operation knob 7 is arranged at a position closer to the operation knob 3 (an example of a second operation knob) than the operation knob 2 in the Y direction. That is, the operation knob 7 is disposed adjacent to the operation knob 3 in the Y direction. In the modification, one or both of the operation knobs 2 and 3 may be omitted, or another operation knob may be added.

Here, the operation knob 7 will be further described with reference to fig. 2 and 3.

Fig. 3 is a sectional view similar to fig. 2 showing a state where the operation knob 7 is located at the second position. In addition, fig. 2 shows a state in which the operation knob 7 is located at the first position.

The operation knob 7 is provided in the opening 126. The operation knob 7 is displaceable in the Y direction between a first position shown in fig. 2 and a second position shown in fig. 3. The second position is on the Y direction negative side of the first position as shown in fig. 2 and 3. The distance between the first position and the second position in the Y direction corresponds to the operation stroke of the operation knob 7. As shown in fig. 1, when the operation knob 7 is located at the first position, the end portion on the positive side in the Y direction is preferably exposed from the opening 126. Further, "exposed from the opening 126" means that the portion of the operation knob 7 protrudes from the entrance surface of the opening 126 (i.e., a surface defined by a straight line connecting the Y-direction positive-side end 124a of the portion 124 and the Y-direction negative-side end 120a of the recess 120 and the X axis) toward the Y-direction positive side. In this case, the portion 124 preferably exposes the upper portion of the operation knob 7 located at the first position. This facilitates the operation (see arrow R1) by the user, thereby improving the operability.

The surface of the operation knob 7 on the Y-direction front side forms a pressing operation surface 720 to be pressed by the user. The pressing operation surface 720 extends in the vertical direction and in the X direction. The pressing operation surface 720 may be processed to improve operability and the like. For example, the pressing surface 720 may be subjected to a crimping process or a plating process for improving the appearance. The pressing operation surface 720 and the wall portion 130 face each other in the Y direction. When the operation knob 7 is located at the first position, the pressing operation surface 720 may abut against the wall portion 130 in the Y direction, or may face the wall portion 130 in the Y direction with a predetermined small gap.

The operation knob 7 and the recess 120 do not face each other in the Z direction. This improves the assembling property. Specifically, the panel member 12 can be assembled (covered) in a button assembly including the operation button 7 in a vertically downward direction (see arrow R2 in fig. 2), and the assembling property is good. In contrast, in the configuration in which the operation knob 7 and the recess 120 face each other in the Z direction, if the panel member 12 is assembled to the knob assembly so as to face downward (see arrow R2 in fig. 2), the recess 120 of the panel member 12 interferes with the operation knob 7, and the assembly becomes impossible or difficult. The button assembly is, for example, a state in which the operation button 7 is assembled to an upper slider 50, a lower slider 52, and the like, which will be described later with reference to fig. 4 and 5.

The operation knob 7 forms a gap Δ (space) in the Y direction with the concave portion 120 when the operation knob is located at the second position as schematically shown in fig. 3.

The upper slider 50 is integrally connected to the lower side of the operation knob 7 as schematically shown in fig. 2 and 3. For example, the operation knob 7 and the upper slider 50 are connected by snap fitting. The lower slider 52 is connected to the upper slider 50 so as not to be displaceable in the Y direction. For example, the upper slider 50 and the lower slider 52 are fitted and connected by a vertical pin. The lower slider 52 is biased toward the Y direction positive side by a spring 90. The other end of the spring 90 (end not on the lower slider 52 side) is supported by the case main body 10. The lower slider 52 includes a sliding contact 54 (see fig. 5) electrically connected to a contact 72 (see fig. 5) on the substrate 70.

The upper slider 50 extends below the gap Δ as schematically shown in fig. 2 and 3. The upper slider 50 has a portion 560 extending below the gap Δ when the operation knob 7 is located at the second position (hereinafter referred to as "gap immediately below portion 560"), and has a through hole 570 in the vertical direction as a communicating unit at the gap immediately below portion 560. The through hole 570 communicates the gap Δ with the space 30 below the upper slider 50 in the vertical direction. The space 30 below the upper slider 50 may be formed between the case member 110 forming the case body 10 and the upper slider 50 as shown in fig. 2. The case member 110 extends above the substrate 70, and has a function of preventing direct communication between the gap Δ and the substrate 70 in the vertical direction via the through hole 570.

The through-holes 570 have a function of allowing foreign matter that can be caught by the gap Δ to fall downward (hereinafter, also referred to as a "foreign matter fall promoting function by the through-holes 570"). That is, the through-hole 570 has a function of dropping the foreign matter entering from the gap Δ toward the space 30 as will be described later. Further, since the foreign matter dropped into the space 30 does not directly reach the substrate 70 due to the case member 110, the circuit and the like on the substrate 70 can be protected from the dropped foreign matter.

Fig. 4 is a perspective view showing details of one example of the upper slider 50, the lower slider 52, and the spring 90. Fig. 5 is a perspective view showing details of one example of the substrate 70 and the sliding contact 54. Fig. 5 also shows the upper slider 50, the lower slider 52, and the spring 90. Fig. 6 is a sectional view showing the relationship of the upper slider 50 and the case member 110.

In the example shown in fig. 4, the upper slider 50 has a claw portion 501 for snap-fitting with the operation knob 7, and slide guide portions 510 are provided on both sides in the X direction. The slide guide 510 is sandwiched by the case member 110 from the upper and lower sides as shown in fig. 6. Therefore, the upper slider 50 is supported by the case body 10 via the slide guide portion 510 so as to allow only the displacement in the Y direction. The upper slider 50 includes cam portions 520 for creating an operation feeling on both sides in the X direction (only one side is visible in fig. 4). The actuator, not shown, engages with the cam portion 520 from the up-down direction.

In the example shown in fig. 5, the lower slider 52 holds the slide terminal portion 80, and the slide contact 54 provided on the lower side of the slide terminal portion 80 is in contact with the board 70. When the lower slider 52 is displaced in the Y direction together with the operation knob 7, the sliding contact 54 slides in the Y direction on the substrate 70, and the electrical connection state with the contact 72 on the substrate 70 changes. Specifically, when the operation knob 7 reaches the second position, the sliding contact 54 is electrically conducted to the contact 72 on the substrate 70 (i.e., an operation signal is generated). In addition, it is also possible to provide a plurality of sets of the sliding contacts 54 and the contacts 72, and generate the operation signal based on a few majority-compliant principles. In this way, the contact 72 of the substrate 70 forms an example of a contact portion that generates an operation signal based on the displacement of the operation knob 7 to the second position. In the modification, a rubber dome switch or the like may be used as the contact portion for generating the operation signal based on the displacement of the operation knob 7 to the second position. For example, in the case of a rubber dome switch, the rubber dome switch may be disposed so as to be displaced in the Y direction.

As described above, in embodiment 1, since the upper slider 50 and the lower slider 52 are provided by utilizing the space below the operation knob 7, the upper slider 50 can be formed relatively large (e.g., larger than the operation knob 7), for example. Therefore, for example, as shown in fig. 6, by providing the slide guide portions 510 on both sides in the X direction, the stability of displacement during the sliding operation can be improved. Further, rigidity can be easily secured to such an extent that the spring is not deformed even by an external force (input via a spring or the like) input via the cam portion 520 or the like.

Next, the effects of example 1 (the function of the wall portion 130 as a protection wall against foreign matter, and the foreign matter fall promoting function by the through-holes 570) will be described with reference to fig. 7 and 8, and fig. 9 and 10, which show comparative examples.

In the comparative example shown in fig. 7, the wall portion 130 is not provided. In this comparative example, when the liquid 101 having high viscosity enters the concave portion 62, the liquid 101 may flow into and solidify between the slide-type operation knob 61 and the panel member 60 (see arrow 63), and the operation knob 61 may be fixed and not be moved.

In contrast, according to example 1, as shown in fig. 9, when the liquid 101 having high viscosity enters the concave portion 120, the liquid 101 moves downward by gravity as well. However, according to embodiment 1, it is blocked by the wall 130 as shown with the liquid 102. That is, due to the barrier function of the wall portion 130, it is difficult for liquid to enter between the operation knob 7 and the wall portion 130, and a failure (fixation of the operation knob 7) occurring in the comparative example shown in fig. 7 can be reduced.

In the comparative example shown in fig. 8, a wall 65 (a wall equivalent to the wall 130) for blocking the liquid is simply provided on the front side (the positive side in the Y direction) of the operation knob 61, but a through hole corresponding to the through hole 570 is not formed in the slider 69. Fig. 8 shows the operation knob 61 in the operation position (in the state after the slide operation toward the Y direction negative side). In this case, since the wall 65 can function in the same manner as the wall 130 of embodiment 1, it is possible to reduce a problem caused by the inflow of liquid between the slide-type operation knob 61 and the panel member 60. On the other hand, in the comparative example shown in fig. 8, a gap Δ in the Y direction can be formed between the wall 65 and the operation knob 61 at the time of the sliding operation of the operation knob 61, and there is a possibility that a large solid 104 such as a snack is sandwiched. If the solid 104 is sandwiched between the wall 65 and the operation knob 61, the solid 104 cannot fall down due to the slider 69, and the operation knob 61 cannot return to the initial position.

In contrast, according to embodiment 1, as shown in fig. 10, similarly to the comparative example shown in fig. 8, when the operation knob 7 is located at the second position, the gap Δ in the Y direction can be formed between the wall portion 130 and the operation knob 7. Therefore, when a large solid 104 such as a snack falls down into the recess 120 or the like, the solid is sandwiched between the operation knob 7 and the wall 130 when the operation knob 7 is operated (when the operation knob is displaced to the second position) similarly due to the gap Δ in the Y direction between the wall 130 and the operation knob 7. However, according to embodiment 1, as shown in fig. 10, the foreign matter drop promoting function realized by the through hole 570 prevents a solid from remaining between the operation knob 7 and the wall portion 130 during the operation of the operation knob 7 (during the displacement to the second position), and thus the defect (the defect that the operation knob 7 cannot return to the first position) generated in the comparative example shown in fig. 8 can be reduced. Specifically, since the solid matter entering between the operation knob 7 and the wall portion 130 falls down toward the space 30 through the through hole 570 (see arrow R3), the problem that the operation knob 61 cannot return to the initial position can be solved. Fig. 10 schematically shows a state G after the object is dropped by a broken line.

In embodiment 1, the through hole 570 is preferably provided in a range overlapping the gap Δ in a plan view when the operation knob 7 is located at the second position in order to improve the foreign matter fall promoting function. Specifically, as shown in fig. 10, the boundary 570a of the through hole 570 on the Y direction negative side is preferably set at the same position in the Y direction as the pressing surface 720 or set on the Y direction negative side with respect to the pressing surface 720. However, if the Y-direction distance between the boundary 570a on the Y-direction negative side of the through hole 570 and the pressing surface 720 is intentionally made smaller than the Y-direction distance of the gap Δ, the boundary 570a on the Y-direction negative side of the through hole 570 may be set to be on the Y-direction positive side with respect to the pressing surface 720. Similarly, the boundary 570b of the through hole 570 on the Y direction positive side is preferably set to the same position in the Y direction as the end 120a of the recess 120 when the operation knob 7 is at the second position, or set to a position on the Y direction positive side than the end 120a when the operation knob 7 is at the second position as shown in fig. 10. Similarly, if the distance in the Y direction between the boundary 570b on the Y direction positive side of the through hole 570 and the end 120a when the operation knob 7 is at the second position is intentionally made smaller than the distance in the Y direction of the gap Δ, the boundary 570b on the Y direction positive side of the through hole 570 may be set to be located on the Y direction negative side of the end 120a when the operation knob 7 is at the second position.

However, when the operation knob 3 is provided adjacent to the operation knob 7 on the side from the first position toward the second position in the sliding direction and displaceable in a direction different from the sliding direction as in embodiment 1, the restriction on the space for disposing the mechanism for the operation knob 7 becomes larger at the position on the Y direction negative side of the operation knob 7 than in the case where the operation knob 3 is not provided. On the other hand, in embodiment 1, since the operation knob 7 is provided in the vicinity of the end portion of the concave portion 120 on the Y-direction negative side, there is a tendency that the space below the concave portion 120 is less restricted than the operation knob 7 and the Y-direction negative side. The arrangement of the slide guide portion 510 of the upper slider 50 and the like in the space below the concave portion 120 is useful from the viewpoint of efficient use of space, but a defect of the comparative example shown in fig. 8 is likely to occur as the opposite surface thereof. Therefore, embodiment 1 is particularly suitable for a case where the operation knob 3 is provided adjacent to the operation knob 7 on the negative side in the Y direction.

Next, a more preferable configuration of the upper slider 50 will be described with reference to fig. 11 and 12 (and fig. 6 described above).

Fig. 11 is a perspective view showing the upper side of the upper side slider 50. Fig. 12 is a cross-sectional view corresponding to a cross-section taken along line B-B of fig. 11.

The upper slider 50 has 2 through holes 570 (an example of a plurality of through holes) in the gap directly below portion 560. The number of the through holes 570 is arbitrary, and may be 1, or 3 or more. The shape of the through-hole 570 is arbitrary, and may be rectangular (elongated hole in the X direction) in a plan view as shown in fig. 11, or may be circular in addition to the rectangular shape. The through holes 570 may be formed so as to be aligned in the Y direction instead of or in addition to the X direction. The size of the through hole 570 is arbitrary, but is preferably determined according to the virtual size of the large solid 104 (see fig. 10) such as a snack, so that the foreign matter dropping promoting function described above can be satisfactorily realized.

As shown in fig. 6, 11, and 12, the upper slider 50 includes a chamfered portion 590 around the through hole 570 on the upper surface. The chamfered portion 590 is provided over the entire outer periphery of the through hole 570. Therefore, the chamfered portion 590 is formed in a Y-direction well portion 572 formed between the through holes 570 in the X-direction, a X-direction well portion 574 extending over the slide guide portion 510 on both sides and located at the Y-direction positive end of the upper slider 50, and the like. The well portion 572 defines the through hole 570 on both sides in the X direction, and therefore chamfered portions 590 are formed on both sides in the X direction.

The chamfered portion 590 is formed by chamfering in an inclined direction narrowing on the upper side as shown in fig. 6 and 12. The upper side narrowing inclination direction at the chamfered portion 590 is a direction that promotes the object on the chamfered portion 590 to fall downward. This ensures the required rigidity of the upper slider 50 and the foreign matter fall promoting function described above. Since the gap lower position 560 at the upper slider 50 has the slide guide portions 510 on both sides in the X direction, it is useful to have a relatively high rigidity. In this regard, the through hole 570 causes a reduction in the rigidity of the upper slider 50, but by realizing a separate well structure (structure including well portions 572 and 574) in the plurality of through holes 570, it is possible to easily ensure the necessary rigidity in the upper slider 50. In a modification, the well portions 572 and 574 may be omitted, and the through hole 570 may be formed as a single slit that opens to the Y-direction positive side.
