Abstract

<P>PROBLEM TO BE SOLVED: To improve operability when pressing a vehicular switch to press a switch disposed by providing a prescribed interval kept from an operation panel. <P>SOLUTION: This vehicular switch 10 is provided with a switch knob 12 and a switch shaft 14 tilted by the tilting movement of the switch knob 12 to press a switch 54. The switch knob 12 rotates with a first rotation fulcrum A as a center, the switch shaft 14 rotates with a second rotation fulcrum B as a center, and a switch shaft part 22 pushed by an actuating shaft 18 presses the switch 54. Since the fulcrum height of the second rotation fulcrum B of the switch shaft 14 is lower than the fulcrum height of the first rotation fulcrum A of the switch knob 12, an amount of lateral displacement of the switch 54 on a contact surface can be lessened. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to an improvement in operability of a vehicle switch, in particular, a vehicle switch that presses a switch arranged at a predetermined interval with respect to an operation panel.

  The vehicle instrument panel is provided with a switch for setting and operating an electronic device such as an acoustic device or an air conditioner mounted on the vehicle. FIG. 6 is a cross-sectional view of a conventional vehicle switch, and FIGS. 6A and 6B show examples of different vehicle switches.

  The vehicle switch 50 shown in FIG. 6A has an operation panel 52 mounted on a vehicle instrument panel (not shown), and a switch 54 is carried on the substrate 56 with a predetermined interval from the operation panel 52. Has been. The operation panel 52 is attached along the surface of the vehicle instrument panel that can be reached by the driver, while the board 56 carrying the switch 54 has to be placed near the components inside the vehicle. . Accordingly, as shown in FIG. 6A, there is a space between the operation panel 52 and the substrate 56, in other words, between the operation panel 52 and the switch 54.

  The switch knob 58 is attached to the operation panel 52 so as to be tiltable about the hinge portion 60 so that a part of the surface is exposed from an opening 52 a formed in the operation panel 52. An operating shaft 62 extends from the back surface of the switch knob 58 toward the switch. Therefore, when the operator presses the switch knob 58, the switch knob 58 tilts with the hinge portion 60 as the pivot point, and the operating shaft 62 presses the switch 54.

  Next, the vehicle switch 70 shown in FIG. 6B will be described, and the same or corresponding members as those in FIG. 6A will be described with the same reference numerals. In the vehicular switch 70 shown in FIG. 6B, the operating shaft 62 is shorter than the vehicular switch 50 in FIG. 6A, and a separate connecting shaft is provided between the shortened operating shaft 64 and the switch 54. 66 is provided. The connection shaft 66 is arranged such that its movement in the vertical direction is guided by the side wall 52 b of the operation panel 52 and the guide 68. As a result, when the operator presses the switch knob 58, the switch knob 58 tilts with the hinge portion 60 as a rotation fulcrum, and the connection shaft 66 pressed by the operating shaft 64 presses the switch 54.

  The switch knob 58 of the vehicle switch 50 described above has a fulcrum height h from the pressing portion of the switch 54 to the rotation fulcrum (hinge portion 60) along the pressing direction. At the time of operation, the switch knob 58 rotates with the hinge portion 60 as a rotation fulcrum, and the tip of the operating shaft 62 moves along the locus indicated by the alternate long and short dash line, so the operating shaft 62 moves laterally on the pressing surface of the switch 54. Has quantity x. As described above, since the distance between the switch knob 58 and the switch 54 is increased in the vehicle switch, the fulcrum height h of the switch knob 58 is large and has a lateral movement amount x. Therefore, there is a problem that the operating shaft 62 cannot push the switch 54 in the vertical direction. For this reason, problems have arisen that the operability of the switch knob 58 is poor or the switch 54 is difficult to operate.

  In order to reduce the movement amount x of the operating shaft 62 in the lateral direction, a structure in which the hinge portion 60 (rotation fulcrum) is moved close to the pressed portion of the switch 54 (point A shown in FIG. 6A) can be considered. . However, in this case, the gap g between the switch knob 58 and the operation panel 52 must be increased so that the operation panel 52 does not interfere with the tilting motion of the switch knob 58.

  On the other hand, in the vehicular switch 70 shown in FIG. 6B, the lateral movement amount is reduced by the shorter operating shaft 64 and the separate connecting shaft 66 as compared with the vehicular switch 50 shown in FIG. ing. However, by inserting another connecting shaft 66, the number of components increases and the tolerance stack increases. For this reason, in order to prevent rattling of the switch knob 58 during non-operation, a push amount of 0.2 to 0.3 mm is given to the connection shaft 66, but there is a problem that dimensional management is difficult.

  Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to improve the operability of a vehicle switch that presses a switch arranged at a predetermined interval with respect to an operation panel.

  The vehicle switch of the present invention includes an operation panel mounted on the vehicle instrument panel, a substrate that supports the switch with a predetermined distance from the operation panel, and a first rotation fulcrum centered on the operation panel. A switch knob that is attached to be tiltable and has an operating shaft extending from the back surface toward the switch, and is attached to the operation panel so as to be tiltable around the second rotation fulcrum, and is disposed between the operating shaft and the switch. A switch shaft that moves when pressed by the operating shaft and presses the switch, and the height of the fulcrum from the pressing part of the switch to the second rotating fulcrum is from the pressing part of the switch to the first rotating fulcrum It is characterized by being smaller than the fulcrum height.

  In the vehicle switch of the present invention, the fulcrum width from the switch pressing portion to the second rotation fulcrum is larger than the fulcrum width from the switch pressing portion to the first rotation fulcrum.

  Furthermore, in the vehicle switch according to the present invention, the switch shaft includes an arm portion having a flexible portion that performs a tilting motion around the second rotation fulcrum, and an operating shaft fixed to the tip of the arm portion. A switch shaft portion disposed between the switches to press the switch.

  According to the present invention, since the switch shaft pressed by the switch knob is provided and the fulcrum height of the switch shaft is made smaller than the fulcrum height of the switch knob, the lateral movement amount of the switch shaft on the switch pressing surface is reduced. can do.

  Hereinafter, modes for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same or equivalent member as the member shown to the prior art mentioned above, and the description is abbreviate | omitted.

Embodiment 1. FIG.
FIG. 1 is a diagram illustrating a cross section of the vehicle switch according to the first embodiment, and is a diagram illustrating a stationary state in which the switch knob is not operated. FIG. 2 is a cross section of the vehicle switch according to the first embodiment. It is a figure which shows, and is a figure which shows the state at the time of the action | operation which operated the switch knob.

  As shown in FIG. 1, the vehicle switch 10 includes an operation panel 52 and a substrate 56 that supports the switch 54 with a predetermined distance from the operation panel 52. Further, the vehicle switch 10 is tilted about the second pivot point by the switch knob 12 attached to the operation panel 52 so as to be tiltable about the first pivot point and the tilting movement of the switch knob 12. And a switch shaft 14 that presses the switch 54. Details will be described below.

  Side walls 52b and 52c facing each other from the back surface of the operation panel 52 toward the substrate 56 are extended. The side wall 52 b extends from the edge of the operation panel 52 toward the substrate 56, and the side wall 52 c extends from the edge of the operation panel 52 slightly inside to the substrate 56. The switch knob 12 is attached to the back surface of the operation panel 52 and the corner at which the side wall 52c is extended so that the hinge portion 16 can be tilted about the rotation fulcrum (first rotation fulcrum A). A part of the switch knob 12 is exposed from the opening 52a of the operation panel 52, and this exposed surface functions as an operation surface pressed by the operator. The operation shaft 18 extends from the back surface of the switch knob 12 toward the switch 54. Accordingly, when the operator presses the switch knob 12, the switch knob 12 tilts the hinge portion 16 about the rotation fulcrum, and the operation shaft 18 moves.

  In the present embodiment, the switch shaft 14 is attached to the operation panel 52 so as to be tiltable about the second rotation fulcrum B, and the operating shaft 18 and the switch 54 are fixed to the tip of the arm portion 20. The switch shaft portion 22 is disposed between the switch shaft portions 22 and presses the switch 54.

  The arm portion 20 is attached to the hinge portion 16 at one end side, and a vertical portion 20a that extends toward the substrate 56 along the side wall 52c of the operation panel 52, and is bent at a substantially right angle on the terminal side of the vertical portion 20a. And a horizontal portion 20b that is stretched in the horizontal direction. The switch shaft portion 22 is fixed to the terminal end (tip portion) of the lateral portion 20 b and is disposed between the operating shaft 18 and the switch 54. It is preferable that the arm portion 20 and the switch shaft portion 22 are integrally formed.

  In this embodiment, the arm part 20 is comprised with the flexible member. Here, since the vertical portion 20a of the arm portion 20 is along the side wall 52c of the operation panel 52, the movement of the vertical portion 20a in the horizontal direction is restricted, and the switch shaft 14 rotates at the point B shown in FIG. It will turn around the fulcrum (second turning fulcrum B). Moreover, since the arm part 20 is comprised by the flexible member, the switch knob 12 can be pressed in an original position with the elastic return force of the horizontal part 20b. In the present embodiment, the arm portion 20 is made of a flexible member, but the lateral portion 20b may be made of a flexible member.

  With such a configuration, when the operator presses the switch knob 12, the switch knob 12 rotates about the first rotation fulcrum A, and the switch shaft portion 22 is pressed by the operating shaft 18, so that the arm portion 20. The horizontal portion 20b is bent and the switch shaft 14 tilts around the second rotation fulcrum B, so that the switch shaft portion 22 can press the switch 54.

  FIG. 3 is a schematic diagram for explaining the first rotation fulcrum and the second rotation fulcrum. The operation of the first rotation fulcrum and the second rotation fulcrum will be described with reference to FIG.

  As shown in FIG. 3, the distances along the pressing direction from the pressing portion of the switch 54 to the first rotation fulcrum A and the second rotation fulcrum B are the fulcrum heights h1 and h2, respectively. The distances in the direction orthogonal to the pressing direction from the part to the first rotation fulcrum A and the second rotation fulcrum B are defined as fulcrum widths w1 and w2, respectively. In the present embodiment, the fulcrum height h2 of the second rotation fulcrum B of the switch shaft 14 is smaller than the fulcrum height h1 of the first rotation fulcrum A of the switch knob 12. The fulcrum widths w1 and w2 are the same. Therefore, as shown in FIG. 2, during operation, the switch shaft 14 rotates about the second rotation fulcrum B having a small fulcrum height h2, so that the lateral movement of the pressing surface of the switch 54 is performed. The quantity x can be reduced. Thereby, the operativity of switch 10 for vehicles can be raised.

  Next, the operation of the vehicle switch 10 of the first embodiment will be described.

  When the operator presses the switch knob 12, the switch knob 12 rotates about the first rotation fulcrum A, and the operation shaft 18 moves. The switch shaft portion 22 is pressed by the movement of the operating shaft 18, the switch shaft 14 rotates about the second rotation fulcrum B, and the switch shaft portion 22 presses the switch 54. Thereby, the switch 54 can be turned on and off. In the present embodiment, the fulcrum height h2 of the second rotation fulcrum B of the switch shaft 14 is smaller than the fulcrum height h1 of the first rotation fulcrum A of the switch knob 12, so that the lateral direction of the switch shaft portion 22 The amount of movement x can be reduced. Further, with this structure, the first pivot fulcrum A of the switch knob 12 can be maintained near the operation panel 52 as in the conventional case, so that the gap g between the operation panel 52 and the switch knob 12 is made a small gap g. be able to.

  Next, when the operator releases the switch knob 12, the switch shaft portion 22 is returned by the elastic return force of the lateral portion 20b, and the switch knob 12 is returned to the original position in the non-operating state as shown in FIG. Maintain state. As described above, the switch knob 12 can be maintained in the return state by the elastic return force of the lateral portion 20b, so that the dimensional management becomes easy.

Embodiment 2. FIG.
FIG. 4 is a diagram illustrating a cross-section of the vehicle switch of the second embodiment. In addition, the same code | symbol is attached | subjected to the same or equivalent member as the member shown in the prior art mentioned above and Embodiment 1, and the description is abbreviate | omitted.

  The vehicle switch 30 of the second embodiment is different from the vehicle switch 10 of the first embodiment in that the switch shaft 32 is integrally formed with the operation panel 52. Thereby, the number of parts can be reduced. The switch shaft 32 in the present embodiment includes a vertical portion 34a extending from the back surface of the operation panel 52 toward the substrate 56, and a horizontal portion 34b bent substantially at right angles and extending in the lateral direction on the terminal side of the vertical portion 34a. And a switch shaft portion 22 that is fixed to the distal end of the lateral portion 34b of the arm portion 34 and disposed between the operating shaft 18 and the switch 54. In this embodiment, since the switch shaft 32 is integrally formed with the operation panel 52, it is made of a hard material. Therefore, in the present embodiment, a thin portion 34c is provided in which the base end portion of the lateral portion 34b is thinner than the other portions, and the switch shaft 32 is tilted about the second rotation fulcrum B. Thereby, the fulcrum height h2 of the 2nd rotation fulcrum B in the switch shaft 32 can be made smaller than the fulcrum height h1 of the 1st rotation fulcrum of the switch knob 12 (refer FIG. 3). Therefore, similarly to the first embodiment, the lateral movement amount on the pressing surface of the switch 54 of the switch shaft portion 22 can be reduced. In the present embodiment, the fulcrum width w2 of the second rotation fulcrum of the switch shaft 32 is larger than the fulcrum width w1 of the first rotation fulcrum of the switch knob 12. Accordingly, the turning radius of the switch shaft 32 is increased, and the amount of movement of the switch shaft portion 22 in the lateral direction can be reduced.

  The operation of the vehicle switch 30 according to the second embodiment is substantially the same as that of the first embodiment, and thus detailed description thereof is omitted.

Embodiment 3. FIG.
FIG. 5 is a cross-sectional view of the vehicle switch of the third embodiment. In addition, the same code | symbol is attached | subjected to the same or equivalent member as the member shown by the prior art and embodiment mentioned above, and the description is abbreviate | omitted.

  The vehicle switch of the third embodiment is an example of a vehicle seesaw switch 40 in which the unique configuration of the present invention is applied to a so-called seesaw type switch. As shown in FIG. 5, for example, the support 42 fixed to the operation panel (not shown) is provided with a switch knob 44 that can be tilted on both sides around the first rotation fulcrum A. The operating shaft 46 is extended toward the switch 54 on both sides. Further, a switch shaft 48 is provided that can be tilted about the second rotation fulcrum B, which is closer to the switch 54 than the first rotation fulcrum A, and is disposed between each operation shaft 46 and the switch 54. Thus, when the switch knob 44 is pressed, the switch knob 12 rotates about the first rotation fulcrum A, the switch shaft 48 rotates about the second rotation fulcrum B, and the switch 54 Can be pressed. Thus, also in the vehicle seesaw switch 40 of the present embodiment, the fulcrum height h2 of the second rotation fulcrum B of the switch shaft 48 is equal to the fulcrum height h1 of the first rotation fulcrum A of the switch knob 44. Since it is smaller, the amount of lateral movement of the pressing surface of the switch 54 of the switch shaft 48 can be reduced.

It is a figure which shows the cross section of the switch for vehicles of Embodiment 1, and is a figure which shows the state at the time of the rest which has not operated the switch knob.
