Description

  The present invention relates to a lever / switch device for operating a contact of a vehicle headlight or the like.

  Examples of conventional lever / switch devices include those shown in FIGS. FIG. 10 is an exploded perspective view showing the mounting relationship of the lever / switch device, and FIG. 11 is a sectional view showing the periphery of the switch portion of the lever / switch device.

  The lever switch device 101 of FIGS. 10 and 11 is for instructing electrical operation. For example, a turn signal switch, a passing switch, a main dimmer switching switch, a wiper washer switch, and the like are used. It has a function.

  The lever / switch device 101 includes an operation lever 103 and a switch unit 105, and the switch unit 105 is attached to the body 106 fixed to the steering column 104.

  The operation lever 103 includes first, second and third levers 109, 107 and 111.

  The first lever 109 has a rotary knob 112 fixed to one end and a first operating rod 113 attached to the other end. A fixed knob 114 is attached to one end of the second lever 107, and a moderator support cylinder 115 is integrally formed with the other end. The moderator support cylinder 115 is provided with a second operating rod 117.

  The third lever 111 is rotatably disposed on the outer peripheral side of the first lever 109 and includes a third operating rod 119 on the distal end side.

  In addition, a moderation spring 121 and a moderation body 123 are provided.

  In the switch unit 105, a movable body 127 is disposed in a case 125, and is rotatably supported by a shaft 127a. A fourth operating rod 129 is provided on the movable body 127. The first lever 109 is rotatably supported by the movable body 127 by a shaft 107a. A pole board 131 is disposed below the case 125. A plurality of fixed contacts are provided on the upper surface side of the pole board 131. On the pole board 131, a first movable board 133, a second movable board 135, a third movable board 137, and a fourth movable board 139 are arranged. The first, third, and fourth movable plates 133, 137, and 139 are arranged so as to be linearly movable in the lever axis crossing direction of the operation lever 103 (the direction orthogonal to the paper surface in FIG. 11), and the second movable plate 135 is These are arranged so as to be linearly movable in the lever shaft direction (left and right direction in FIG. 11).

  The headlamp is turned on and off by the linear movement of the first movable platen 133, the main and dimmer switching and passing are performed by the linear movement of the second movable platen 135, and the straight line of the third movable platen 137 is obtained. The fog lamp is turned on and off by the movement, and the direction indicator lamp is blinked by the linear movement of the fourth movable platen 139.

  The first, second, third and fourth movable plates 133, 135, 137 and 139 are engaged with the first, third and fourth movable plates 133, 137 and 139 in order to move them linearly. Portions 141, 143, and 145 are provided, and the second movable platen 135 is provided with a hole 147.

  For example, when the first lever 109 is operated to rotate the shaft by operating the rotary knob 112, the first operating rod 113 is interlocked, and the first operating rod 113 applies an engaging force to the engaging portion 141, and the first operating rod 113 is engaged. The movable platen 133 moves in the lever axis crossing direction. This movement turns off the headlamp as described above. The same applies to the movement of the third movable platen 137 by the shaft rotation operation of the third lever 111.

  When the operation lever 103 is swung around the shaft 107a for switching between main and dimmer and passing, the second movable plate 135 moves linearly in the lever shaft direction via the second operation rod 117.

  At this time, since the first operating rod 113 and the third operating rod 119 move in the direction along the engaging portions 141 and 143, the first and third movable plates 133 and 137 do not operate.

  When the operating lever 103 is swung around the shaft 127a to blink the direction indicator lamp, the fourth movable platen 139 moves linearly in the lever axis crossing direction via the fourth operating rod 129.

  At this time, the first and third operating rods 113 and 119 operate in the direction perpendicular to the paper surface engaged with the engaging portions 141 and 143, but the clearance is set by setting the clearances for the engaging portions 141 and 143 in the same direction. The first and third movable plates 133 and 137 do not operate without engaging with the joint portions 141 and 143.

  Thus, various lever operations can be performed smoothly.

  However, in such a structure, since the first movable plate 133 (engagement portion 141) and the third movable plate 137 (engagement portion 143) are provided side by side, the case 125 has a horizontal direction (FIG. 11). There was a problem that the length of the case 125 (in the left-right direction) was increased and the lever / switch device was increased in size.

FIG. 7 is a bottom view of the main part shown with the pole board, the under cover, and the first movable board removed.

  As shown in FIGS. 3 to 7, the first and second movable plates 41 and 43 are partially overlapped. That is, a first fitting portion 45 described later is disposed at a position where the first and second movable plates 41 and 43 are overlapped. The first and second movable plates 41 and 43 are integrally formed with first and second fitting portions 45 and 47, respectively. The first and second fitting portions 45 and 47 are arranged offset to the T / S rotation axis P side with respect to the first and second movable plates 41 and 43.

  The first and second fitting portions 45 and 47 are formed in a cross-sectional shape that is open on one side and surrounds three sides. Both the walls of the first and second fitting portions 45 and 47 are engaged with each other in the linear movement direction of the first and second movable plates 41 and 43 as shown in FIGS. It becomes walls 45a, 45b, 47a, 47b.

  The first and second fitting portions 45 and 47 have a cross-sectional shape that surrounds the first and second engagement walls 45a, 45b, 47a, 47b and the walls 45c, 47c, and the open side is formed in the case 25. It faces the regulating wall 49 and is arranged adjacent to it. The walls 45c and 47c are disposed opposite to the regulation wall 49 with a space therebetween.

  The restriction wall 49 can be formed integrally with either the first fitting portion 45 or the second fitting portion 47 or both.

  Thus, the first and second fitting portions 45 and 47 are adjacent to each other with the restriction wall 49 interposed therebetween.

  The first and second end portions 19a and 23a of the first and second arms 19 and 23 are fitted to the first and second fitting portions 45 and 47, respectively.

  The restriction wall 49 is disposed between the first and second arms 19 and 23 on the T / S rotation axis P of the movable body 31. The restriction wall 49 is configured to prevent the first and second levers from rotating with respect to the movable body 31 around the shaft 35 of the first and second levers 13 and 15 (rotation in the direction along the steering column). The movement of the arms 19 and 23 is restricted.

  FIG. 8 is a perspective view showing the relationship between the first arm and the first movable platen as viewed from the first and second lever sides, and FIG. 9 is a diagram of the first and second arms and the second movable platen. It is the perspective view which showed the relationship and was seen from the 1st, 2nd lever side.

  As shown in FIGS. 3 and 8, the first arm 19 has a frame-shaped first base portion 19b formed integrally with the first tip portion 19a. The first tip 19a of the first arm 19 is provided with a first hemispherical portion 19c with the adjacent side cut. The adjacent side of the first tip portion 19a including the first hemispherical portion 19c is formed on the flat surface portion 19d. The flat portion 19d faces the regulation wall 49 with the T / S rotation axis P interposed therebetween.

  The first base portion 19b is formed in a frame shape, and a rib 19ba is provided at the center. The distal end of the second lever 15 and the distal end of the first lever 13 protruding from the second lever 15 are also formed in a rectangular shape on the outer periphery, and are provided with slits 15a and 13a.

  The first base 19b of the first arm 19 is fitted to the tip of the first lever 13, and the rib 19ba is fitted to the slit 13a. This attachment prevents the first arm 19 from rotating around the axis of the first lever 13.

  The first base 19b of the first arm 19 is rotatably supported at the tip of the first lever 13 via a pivot 19e.

  The first arm 19 rotates along the lever shaft with respect to the first lever 13 by the rotation prevention by the fitting of the first base portion 19b to the tip of the first lever 13 and the rotation support by the pivot 19e. It is possible and non-rotatably mounted around the lever axis.

  The first arm 19 can be prevented from rotating around the axis of the first lever 13 only by fitting the pivot 19e of the first base portion 19b and the first lever 13, but this fitting portion It is conceivable that the fitting is disengaged due to the load on the surface, and the rib 19ba and the slit 13a are fitted to prevent rotation.

  In this attached state, the first distal end portion 19a of the first arm 19 is fitted to the first fitting portion 45 as described above. The first tip 19 a of the first arm 19 has a clearance with respect to the first engagement walls 45 a and 45 b of the first fitting portion 45 in the linear movement direction of the first movable platen 41. Yes.

  As shown in FIGS. 3 and 9, the second arm 23 and the second fitting portion 47 are configured in the same manner as the first arm 19 and the first fitting portion 45.

  In the second arm 23, a frame-shaped second base 23 b is integrally formed with the second tip 23 a, and the second base 23 b is fitted to the tip of the second lever 15. The second tip 23a of the second arm 23 is provided with a second hemispherical part 23c with the adjacent side cut. The adjacent side of the second tip portion 23a including the second hemispherical portion 23c is formed in a planar portion 23d along the T / S rotation axis P.

  The fitting portion of the second arm 23 to the second lever 15 is separated from the T / S rotation axis P, and the tip 23a of the second arm 23 is located at a position adjacent to the T / S rotation axis P. The second arm 23 has a generally U-shaped cross-sectional view from the fitting portion with the second lever 15 toward the distal end side of the second lever 15 so that the second arm 23 can be disposed in the fitting portion 47 of the second movable plate 43. It has a bent shape.

  Therefore, both the first arm 19 and the second arm 23 can be fitted to the fitting portions 45 and 47 of the corresponding movable plates 41 and 43 at positions adjacent to the T / S rotation axis P, and each of them can be rotated by T / S rotation. They can be arranged at approximately the same distance from the axis P.

  This attachment prevents the second arm 23 from rotating about the axis of the second lever 15.

  The second base 23b of the second arm 23 is rotatably attached to the tip of the second lever 15 via a pivot 23e.

  The second arm 23 rotates with respect to the second lever 15 along the lever shaft by the rotation prevention by the fitting of the first base 23b to the tip of the second lever 15 and the rotation support by the pivot 23e. It is possible and non-rotatably mounted around the lever axis.

  In this attached state, the second tip 23 a of the second arm 23 is fitted into the second fitting portion 47. The second tip 23 a of the second arm 23 has a clearance with respect to the second engagement walls 47 a and 47 b of the second fitting portion 47 in the linear movement direction of the second movable plate 43. Yes.

  The hemispherical portions 19c and 23c are uniform between the walls 45c and 47c with respect to any movement of the first and second arms 19 and 23 when the operation lever 3 is operated in the direction of the arrow C or D. In order to make contact (point contact is possible), the shape is a hemisphere.

  In such a configuration, when the operation lever 3 is operated in the direction of the arrow A or B to blink the turn signal, the first and second tip portions 19a and 23a of the first and second arms 19 and 23 are It only turns slightly around the T / S rotation axis P, and can be relatively moved within a slight clearance in the first and second fitting portions 45 and 47.

  For this reason, in the operation of blinking the turn signal of the operation lever 3, the first and second movable boards 41 and 43 are not interlocked and do not move linearly.

  When the operation lever 3 is operated in the direction of the arrow C or D to switch the main dimmer of the headlamp, the first and second arms 19 and 23 are connected to the first and second fitting portions 45. , 47 are engaged with the walls 45c, 47c and the regulating wall 49 to restrict the operation. This regulation can prevent malfunction.

  At this time, the base portions 19b and 23b of the first and second arms 19 and 23 can be rotated by the pivots 19e and 23e with respect to the first and second levers 13 and 15, and the first and second movable plates can be rotated. The operation lever 3 can be operated in the direction of the arrow C or D without any reaction force from 41 and 43 without difficulty.

  When the first rotary knob 10 is operated, the first lever 13 rotates about the axis, and the first arm 19 rotates together. By the rotation of the first arm 19, the first tip 19 a moves beyond the clearance with respect to the first fitting portion 45, engages with the first engagement walls 45 a and 45 b, and the first movable platen 41. Can be moved linearly.

  With the linear movement of the first movable platen 41, the headlamp and the small lamp can be turned on and off.

  When the second rotary knob 12 is operated, the second lever 15 rotates about the axis, and the second arm 23 rotates together. Due to the rotation of the second arm 23, the second distal end portion 23a operates more than the clearance with respect to the second fitting portion 47, and engages with the second engagement walls 47a and 47b to cause the second movable plate 43 to move. Can be moved linearly.

The fog lamp can be turned on and off by the linear movement of the second movable platen 43.
[Effect of Example]
In the embodiment of the present invention, a movable body 31 rotatably supported by the case 25 and a pole plate 37 on the case 25 side are arranged so as to be movable in a direction perpendicular to the rotational axis of the movable body 31. A plurality of first and second movable plates 41 and 43 that perform contact operation with respect to the plate 37 and a movable body 31 are supported so as to be able to swing and rotate. A plurality of first and second levers 13 and 15 for causing the second movable plates 41 and 43 to contact each other are provided, and the first and second movable plates 41 and 43 are at least partially overlapped. .

  For this reason, the length of the case can be shortened (the length of the case 25 in FIGS. 2 and 3 in the left-right direction can be shortened), and the lever / switch device can be downsized.

  A plurality of first and second levers 13 and 15 which are provided on the first and second movable plates 41 and 43 and are adjacent to each other across the rotation axis of the movable body 31 along the lever shaft. The first and second arms 19 and 23 are respectively fitted with first and second fitting portions 45 and 47, and the first and second movable plates 41 and 43 are overlapped with each other. The joint part 45 was arranged.

  For this reason, the space | interval of the 1st, 2nd arms 19 and 23 provided along a lever axis | shaft can be made small, and the length of the said case can be shortened reliably.

  A movable body 31 rotatably supported by the case 25 and a pole board 37 on the case 25 side are arranged so as to be movable in a direction perpendicular to the rotation axis of the movable body 31 with respect to the pole board 37. First and second movable plates 41 and 43 that perform contact operation, and first and second levers 13 and 15 that are rotatably supported by the movable body 31 and arranged so as to be axially rotatable are provided. The lever / switch device 1, which is provided on the first and second movable plates 41 and 43 and adjacent to the first and second fitting portions 45 and 47 with the rotation axis of the movable body 31 therebetween. The first and second tips are supported by the first and second levers 13 and 15 so that the base portions 19b and 23b can rotate along the lever shaft and cannot rotate about the lever shaft at an axis perpendicular to the lever shaft. The portions 19a and 23a are adjacent to each other with the rotation axis of the movable body 31 interposed therebetween. The first and second arms 19 and 23 fitted to the first and second fitting portions 45 and 47, and the first and second arms 19 and 23 formed between the first and second arms 19 and 23, respectively. , A restriction wall 49 for restricting the movement of the first and second arms 19 and 23 in the lever axis direction with respect to the rotation of the second levers 13 and 15, and the first and second fitting portions 45, 47 is engaged with the first and second arms 19 and 23 by the rotational movement of the first and second arms 19 and 23 due to the shaft rotation of the first and second levers 13 and 15. Engagement walls 45a, 45b, 47a, and 47b for causing the first and second movable plates 41 and 43 to perform a contact operation are provided.

  For this reason, the 1st, 2nd front-end | tip parts 19a and 23a which the 1st, 2nd arms 19 and 23 fit to the 1st and 2nd fitting parts 45 and 47 are brought close to the T / S rotating shaft P. The axial width of the operation lever 3 of the switch unit 7 can be reduced.

  Moreover, the first and second arms 19 and 23 bring the first and second tip portions 19a and 23a fitted to the first and second fitting portions 45 and 47 closer to the T / S rotation axis P. Therefore, when the operation lever 3 is operated around the T / S rotation axis P, the first and second rotation knobs 10 and 12 are operated to rotate the first and second levers 13 and 15 along with the shaft rotation. In order to ensure the contact operation of the first and second movable plates 41 and 43, the operating rod does not have to be lengthened as in the prior art, so the width in the direction perpendicular to the axial direction of the operating lever 3 of the switch unit Can be reduced.

  First hemispherical portions 19c and 23c, which are cut at the adjacent sides, are provided at the first tip portions 19a and 23a of the first and second arms 19 and 23, respectively.

  Therefore, the first and second tip portions 19a and 23a can be brought closer to the T / S rotation axis P, and when the operation lever 3 is operated in the direction of the arrow C or D, the first and second arms The first and second arms 19 and 23 can operate between the walls 45c and 47c with respect to any movement of the nineteen and twenty-three movements, without receiving a reaction force from the first and second movable plates 41 and 43. The operation of the operation lever 3 in the direction of the arrow C or D can be performed without difficulty.

  The first and second fitting portions are formed with walls facing each other with a space from the restriction wall.

  For this reason, when the operation lever 3 is operated in the C and D directions, malfunctions can be prevented by restricting the operation of the first and second arms 19 and 23 by the wall.

  That is, for example, when the operating lever 3 is operated in the D direction, the first arm 19 does not come out in the lever axial direction from the first fitting portion 45 by the wall, so in this state, the first turning knob 10 ( Even if the operation lever 3) is rotated to the small lamp lighting position, the first movable platen 41 operates and the small lamp can be reliably turned on.
