Description

[Technical Field]

[0001] The present invention relates to an operation button structure and an in-vehicle device equipped with the same. [Background technology]

[0002] Patent Document 1 describes a button structure that allows a contact point on a circuit board on the back side of the button to be pressed normally no matter which part of the button is pressed. The push button structure described in Patent Document 1 is provided on a panel, and a hinge connected to one end of the back side of the push button extends toward the other end of the back side of the push button, and is configured so that the panel supports it at a position beyond that other end. Therefore, the hinge is a long member that extends from one end of the push button to a position beyond the other end, and is therefore easily flexible.

[0003] This allows the hinge to bend smoothly no matter which position on the push button is pressed, so that the switch contacts can be pressed normally regardless of the part that is pressed. Hereinafter, the action of the push button pressing the switch contacts will be referred to as the switch action. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-311050 Summary of the Invention [Problem to be solved by the invention]

[0005] In a car navigation device as an in-vehicle device equipped with an image display unit and an operation unit with multiple push buttons, the front panel size is set to a predetermined size such as 2DIN, and it is desirable that the image display unit be as large as possible within that size. On the front panel of such a car navigation device, multiple push buttons are arranged along the edge of the screen as an operation unit in a section that forms the housing frame on the outside (for example, the right side) of one edge of the display image unit. Therefore, if the display image unit is made larger, the space for the operation unit becomes narrow and limited. Therefore, it is structurally difficult to make the push button of the operating unit a conventional push button that uses a long hinge that extends from one end of the button to a position beyond the other end, as described in Patent Document 1, and improvements are desired.

As shown in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] A push button structure according to an embodiment of the present invention and an in-vehicle device equipped with the same will be described using a push button structure BK of an example and an in-vehicle device 91 equipped with the same. The in-vehicle device 91 of the example is a car navigation device.

[0011] (Example) FIG. 1 is a front view of an in-vehicle device 91, which is an example of an in-vehicle device according to an embodiment of the present invention. The in-vehicle device 91 is a so-called 2DIN size car navigation device that is mounted on the dashboard of a vehicle such as an automobile. For ease of explanation, the up, down, left, and right directions are defined by the directions of arrows in FIG. 1. The front side of the paper in FIG. 1 is the front side, and the back side of the paper is the rear side.

[0012] The in-vehicle device 91 includes a housing 1, an image display unit 2, and an operation unit 3G. The housing 1 is in the shape of a six-sided box, and the front portion has an opening 13 in the center, and is formed in a frame shape so that the image display unit 2 is exposed inside the opening 13. An operation unit 3G is disposed in a portion that becomes the frame portion on the right outer side of the opening 13. The operation unit 3G has a plurality of push buttons 3a to 3c, 3, 3d to 3f that are aligned in the vertical direction.

[0013] The push button 3, located in the center of the operation unit 3G in the vertical direction, has a portion that is pressed with a finger exposed as a rectangular button decoration 32 in front view. The button decoration 32 is smaller in the left-right direction than the other push buttons 3a to 3c and 3d to 3f, and because it is smaller, edges 11 and 12 of the housing 1 extend to the left and right of the push button 3, respectively, to accentuate the push button 3.

[0014] 2 is a perspective view showing the internal structure of the operation unit 3G as seen from the front diagonally downward right side. In FIG. 2, the push buttons 3a to 3c and the push buttons 3d to 3f are not shown, and only the push button 3 is shown. The operation unit 3G has a substrate 5, switches 51a to 51c, 51, 51d to 51f which are tactile switches mounted on the front surface of the substrate 5, and a plurality of light emitting elements 52 which are light sources. The switches 51a to 51c, 51, 51d to 51f are mounted at positions corresponding to the push buttons 3a to 3c, 3, 3d to 3f, respectively. In this example, there are four light-emitting elements 52, which are mounted at separate locations on the substrate 5 at positions corresponding to the vertices of a rectangle within the area included in the button decorative part 32 when viewed from the front.

[0015] The push button 3 will be described in detail with reference to Figures 3 and 4. Figure 3 is a perspective view showing the push button structure BK including the push button 3, as seen from the upper right rear. Figure 4 is a cross-sectional view taken along the line S4-S4 in Figure 1.

[0016] The push button 3 is a button that is pressed down to close the contacts of the switch 51, and includes a button body 31 and a button decoration 32. The button body 31 is made of a milky white resin that diffuses and transmits light, while the button decoration 32 is made of a light-transmitting resin, such as a blue resin. Examples of resins for the button body 31 are PC (polycarbonate resin) and for the button decoration 32 are PMMA (polymethyl methacrylate resin).

[0017] As shown in Figure 3, the button main body 31 has a rectangular flat base 311 arranged opposite the substrate 5, restricting legs 313, 314, a side wall 319, a first fixing leg 3F1 and a second fixing leg 3F2, and a push-in column 312. The restricting legs 313 and 314 are plate-shaped portions that extend rearward from the lower right corner and upper right corner of the base 311, respectively. The side wall 319 is a wall that rises rearward from the left edge of the base 311. The rear end of the side wall 319 is closer to the base 311 than the rear end of the restriction legs 313, 314.

[0018] The first fixed leg 3F1 is formed to extend further downward from the rear end below the side wall portion 319, and has a leg portion 315 that extends straight downward, and a fixed leg portion 316 that extends rearward from the tip of the leg portion 315. The second fixed leg 3F2 is formed to extend further upward from the upper rear end of the side wall portion 319, and has a leg portion 317 that extends straight upward, and a fixed leg portion 318 that extends rearward from the tip of the leg portion 317.

[0019] The bases of fixed legs 316 and 318, which are the tip portions, engage with grooves 111 formed in housing 1, and are arranged to be sandwiched between housing 1 and substrate 5. In detail, as shown in Figures 3 and 4, the bases of fixed legs 316 and 318 engage with grooves 111, so that movement of button body 31 in the vertical and horizontal directions relative to housing 1 in its natural state is restricted. In this state, the rear ends of the fixing legs 316, 318 come into contact with the board 5, so that the rearward movement of the button body 31 relative to the housing 1 in its natural state is restricted.

[0020] The push-in column 312 is erected facing rearward in the center in the vertical direction near the right edge of the base 311. As shown in Fig. 2, the push-in column 312 is a member that pushes in the contacts of the switch 51, and is formed so that its cross section is T-shaped and has high rigidity. As shown in FIG. 4, the push-in column 312 is disposed in a natural state so that its tip is spaced forward a predetermined distance Ha from the upper surface of the switch 51 and faces the switch 51. Meanwhile, the tips of the restricting legs 313 (not shown in FIG. 4) and 314 are positioned a predetermined distance Hb forward from the upper surface of the substrate 5. Here, the distance Hb is set as the sum (Ha1+Ha2) of the push-in amount Ha1 necessary for the switch 51 to operate, including the distance Ha, and the push-in margin Ha2, which is the maximum amount of further push-in that the switch 51 allows after it operates. This prevents the push-in column 312 from being pushed too hard into the switch 51.

[0021] In the above-mentioned push button 3, no matter which position on the base 311 is pressed, the first fixed leg 3F1 and the second fixed leg 3F2 are deformed well, the base 311 is pressed, and the pressing pillar 312 presses the switch 51. This pushing operation will be described with reference to FIGS. 5 and 6 for the cases where the vicinity of the left edge of the button decorative part 32 is pushed in and the case where the vicinity of the right edge is pushed in. FIG.

[0022] FIG. 5 shows the operation of the push button 3 when the vicinity of the left edge of the button decorative part 32 is pressed with a force F1. As shown in Figure 5, when a rearward force F1 is applied near the left edge of the button decorative portion 32, the leg 315 of the first fixed leg 3F1 and the leg 317 of the second fixed leg 3F2, which are long members in the vertical direction, undergo flexural deformation (bending deformation) to allow the button main body portion 31 side to move rearward as shown by arrow DR1. As a result, the push-in column 312 also moves rearward as shown by the arrow DR2, and pushes in the contact of the switch 51.

[0023] FIG. 6 shows the operation of the push button 3 when the vicinity of the right edge of the button decorative part 32 is pressed with a force F2. As shown in Fig. 6, when a rearward force F2 is applied to the button decorative part 32 by the user's finger or the like, a bending moment is applied to the leg 315 of the first fixed leg 3F1 and the leg 317 of the second fixed leg 3F2 because the point of application of the force is far enough to the right from the fixed legs 316, 318 supported on the edge 11 of the housing 1. Because the legs 315 and 317 are members that are long in the vertical direction, they are twisted and deformed counterclockwise in Fig. 6 around the vertical axis as indicated by the arrow DR3. As a result, the push-in column 312 also moves rearward as shown by the arrow DR4, and pushes in the contact of the switch 51.

[0024] The push button structure BK using the above-mentioned push button 3 has a first fixed leg 3F1 and a second fixed leg 3F2, which are parts that deform when pressed against the button decorative part 32, formed so that when viewed from above (from behind), they extend outward in the vertical direction from one edge (one edge) in the left-right direction of the button main body part 31 in a first direction along that edge. Therefore, the width of the push button 3 in the left-right direction is substantially the same as the width of the button body 31, making it extremely compact. Furthermore, the first fixing leg 3F1 and the second fixing leg 3F2 are substantially bent when the side closer to them on the button decorative part 32 (base 311) is pressed in, and are twisted when the side farther from them is pressed in, causing the pushing column 312 to move in the pushing direction. This allows the push button structure BK to perform stable switching operation regardless of the part pressed, even if the placement space is narrow.

[0025] The embodiment described above in detail is not limited to the configuration, and modifications may be made without departing from the spirit of the present invention.

[0026] 7 is a perspective view of push button 4, a variation of push button 3, as seen from the upper left rear diagonally. The up, down, left, right, front, and back directions correspond to the directions when push button 4 is used in place of push button 3 in push button structure BK.

[0027] The push button 4 is supported by being sandwiched between the edge 11 of the housing 1 and the substrate 5, and presses the switch 51, and has a button main body 41 that corresponds to the button main body 31. The push button 4 is integrally provided with a button ornamental part 42 that corresponds to the button ornamental part 32 on the front side of the button main body 41. The button body 41 is made of a milky white resin that diffuses and transmits light, such as PC (polycarbonate).

[0028] The button body 41 has a rectangular flat base 411, restricting legs 413 and 414, a first fixing leg 4F1, a second fixing leg 4F2, and a push-in column 412. In addition, Fig. 7 shows the button body 41 having a frame wall 419. The restricting legs 413 and 414 are plate-shaped portions that extend rearward from the lower right corner and upper right corner of the base 411, respectively. The frame wall portion 419 is a frame-shaped wall formed so as to extend rearward at a position roughly corresponding to the edge of the button decorative portion of the base portion 411. This wall is not necessarily a necessary part, but is formed in order to keep the light from the light-emitting element 52 mounted on the substrate 5 inside the frame wall portion 419 and guide it through the button main body portion 41 to the button decorative portion 42.

[0029] The first fixing leg 4F1 is formed to extend rearward from the lower left end of the base 411. The first fixing leg 4F1 has a first leg 415a, a second leg 415b, a third leg 415c, a fourth leg 415d, a fifth leg 415e, and a fixing leg 416. The first leg 415a is a portion that extends rearward from the lower left end of the base 411. The second leg portion 415b is a portion that bends and extends upward from the rear end of the first leg portion 415a. The third leg portion 415c is a portion that bends and extends rearward from the upper tip of the second leg portion 415b. Fourth leg 415d is a portion that bends downward from the rear end of third leg 415c and extends further downward than first leg 415a. Fourth leg 415d is formed so as not to come into contact with substrate 5 not only in its natural state but also when base 411 is pushed backward and deformed to operate switch 51. Fifth leg 415e is a portion that is bent forward from the lower tip of fourth leg 415d. The fixed leg 416 is formed at the front end of the fifth leg 415e and is supported by the edge 11 of the housing 1. That is, the fixed leg 416 has a first leg 415a, a third leg 415c, and a fifth leg 415e that extend in a second direction, which is the front-to-rear direction, a second leg 415b that extends in a first direction perpendicular to the second direction and connects the first leg 415a and the third leg 415c, and a fourth leg 415d that connects the third leg 415c and the fifth leg 415e.

[0030] The second fixing leg 4F2 has a shape that is symmetrical to the first fixing leg 4F1 in the up-down direction. That is, the second fixing leg 4F2 is formed to extend rearward from the upper left end of the base 411. The second fixing leg 4F2 has a first leg 417a, a second leg 417b, a third leg 417c, a fourth leg 417d, a fifth leg 417e, and a fixing leg 418. The first leg 417a is a portion that extends rearward from the upper left end of the base 411. The second leg portion 417b is a portion that bends and extends downward from the rear end of the first leg portion 417a. The third leg portion 417c is a portion that bends and extends rearward from the lower tip of the second leg portion 417b. Fourth leg 417d is a portion that bends upward from the rear end of third leg 417c and extends further upward than first leg 417a. Fourth leg 417d is formed so as not to come into contact with substrate 5 not only in its natural state but also when base 411 is pushed backward and deformed to operate switch 51. Fifth leg portion 417e is a portion that is bent forward from the upper tip of fourth leg portion 417d. The fixed leg 418 is formed at the front end of the fifth leg 417e and is supported by the edge 11 of the housing 1. That is, the fixed leg 417 has a first leg 417a, a third leg 417c, and a fifth leg 417e that extend in a second direction, which is the front-to-rear direction, a second leg 417b that extends in a first direction perpendicular to the second direction and connects the first leg 417a and the third leg 417c, and a fourth leg 417d that connects the third leg 417c and the fifth leg 417e.

[0031] Fixed leg 416 and fixed leg 418 have openings 416a, 418a with axes extending in the front-to-rear direction, and engage with dowels (not shown) that protrude rearward and are formed on housing 1. As a result, push button 4 is sandwiched between housing 1 and board 5, and its movement in all directions is restricted in its natural state.

[0032] The push-in pillar 412 is erected facing rearward in the vertical center near the right edge of the base 411. Like the push-in pillar 312 of the push button 3, the push-in pillar 412 is a member that pushes in the switch 51, and is formed so that its cross section is T-shaped to make it less likely to bend.

[0033] In the above-mentioned push button 4, when any position on the base 411 is pressed, the first fixed leg 4F1 and the second fixed leg 4F2 are easily deformed, the base 411 is pressed, and the pressing pillar 412 presses the switch 51. This pushing operation will be described with reference to FIGS. 8 and 9 for the cases where the vicinity of the left edge of the base 411 is pushed in and the case where the vicinity of the right edge is pushed in. FIG.

[0034] FIG. 8 shows the operation of the push button 3 when the vicinity of the left edge of the button decoration part 42 integrated with the front side of the base part 411 is pressed with a force F1. 8, when a backward force F1 is applied to the button decorative part 42 by a finger, the second leg 415b and the fourth leg 415d of the first fixing leg 4F1 and the second leg 417b and the fourth leg 417d of the second fixing leg 4F2 are flexed and deformed as shown by arrow DR5 to allow the button main body 41 to move backward. This is because the second leg 417b and the fourth leg 417d are members that are sufficiently long in the vertical direction. As a result, the push-in column 412 also moves rearward as shown by the arrow DR6, and pushes in the contact of the switch 51.

[0035] Here, the first fixed leg 4F1 has a plurality of members extending in the vertical direction. That is, in this example, two legs, the second leg 415b and the fourth leg 415d, extend in the vertical direction, and there are many portions that are primarily bent and deformed by the force F1, making it easier to bend and deform. The same is true for the second fixed leg 4F2. Therefore, the pressing operation of the switch 51 when the force F1 is applied is performed stably and reliably.

[0036] FIG. 9 shows the operation of the push button 4 when the right edge of the button decorative part 42 is pressed with a force F2. As shown in Figure 9, when a backward force F2 is applied to the button decorative portion 42 by the user's finger or the like, a bending moment is applied to the first fixed leg portion 4F1 and the second fixed leg portion 4F2 around an axis extending in the vertical direction indicated by the arrow DR7. The first fixed leg 4F1 has a plurality of parts extending in the front-rear direction, namely, a first leg part 415a, a third leg part 415c, and a fifth leg part 415e. The second fixed leg 4F2 has a plurality of portions extending in the front-rear direction, namely, a first leg portion 417a, a third leg portion 417c, and a fifth leg portion 417e. Therefore, the first fixed leg 4F1 and the second fixed leg 4F2 are easily torsionally deformed mainly by the bending moment indicated by the arrow DR7. As a result, the push-in column 412 moves rearward in the direction of arrow DR8 toward the board 5, and pushes in the switch 51.

[0037] As described above, the first fixed leg 4F1 has a plurality of members extending in the front-rear direction. That is, in this example, the three legs, the first leg 415a, the third leg 415c, and the fifth leg 415e, extend in the front-rear direction, and there are many portions that are easily twisted and deformed by the force F2. Therefore, the pressing operation of the switch 51 by the application of the force F2 is performed stably and reliably.

[0038] The push button structure BK using the above-mentioned push button 4 has a first fixed leg and a second fixed leg, which are parts that deform when pressed against the button decorative part 42, formed so as to extend in the vertical direction from one of the left-right edges of the button main body part 41. Therefore, the width of the push button 4 in the left-right direction is substantially the same as the width of the button body 41, making it extremely compact.

[0039] As a result, the push button structure BK, by using the push button 4, can provide a more stable switch operation regardless of the part that is pressed, even if the placement space is narrow.

[0040] In addition, in both the push button 3 and the push button 4, the rear side of the button decorative portion 32, 42 is open, and the light emitted from the light-emitting element 52 enters the button decorative portion 32, 42 through the button main body 31, 41 without being blocked. This allows the button decorative portion 32, 42 to emit light uniformly over its entire surface, resulting in excellent design.

[0041] Although the push buttons 3 and 4 have been shown as examples in which the button main body 31, 41 can be indirectly pressed by pressing the button decorative part 32, 42 with a finger, thereby applying force, they may not be provided with the button decorative part 32, 42. In this case, the button main body 31, 41 is directly pressed with a finger or the like, and the switch 51 is pressed by the pressing posts 312, 412. [Explanation of symbols]
