JP 2002-145028 A

  In the above conventional one, the middle part of the operation lever having the operation part on one end side is rotatably supported on the vehicle body, and the wire is connected to the other end part of the operation lever. In some cases, the connecting point of the wire to the other end of the operating lever moves on an arc centering on the rotation fulcrum of the operating lever to pull the wire. That is, the wire is pulled while displacing the connecting point of the wire to the operation lever in a direction perpendicular to the pulling direction of the wire, and the invalid stroke is relatively large. For this reason, it cannot be said that the ratio of the pulling stroke of the wire to the operation stroke of the operation lever is large, and the operation efficiency is low. Therefore, if the rotation fulcrum of the operating lever and the length between the operating parts are set short, the operating efficiency can be improved, but the operating lever is required to obtain the traction force required to set the wheel brake to the parking brake state. Therefore, the length cannot be set as short as a dark cloud.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an operation mechanism for a vehicular device that increases the operation efficiency of an operation lever while avoiding an increase in operation load. .

  In order to achieve the above-described object, the present invention provides a wire that allows an operation lever having an operation portion on one end side to be operated by a vehicle driver to be pivotally supported on a vehicle body, and activates a vehicle device in accordance with the action of traction force. However, in the operation mechanism of the vehicle equipment that is linked and connected to the operation lever so as to be pulled according to the operation of the operation lever, the intermediate portion is supported rotatably on the vehicle body via the first support shaft. A link is pivotally connected to the other end of the operation lever via a link pivot shaft parallel to the first support shaft, and the wire is connected to the link at a position offset from the link pivot shaft. The other end of the connecting rod, which is connected and is rotatably supported on the vehicle body via a second support shaft that is parallel to the first support shaft, rotates the operation lever according to the operation by the vehicle driver. Around the axis of the second spindle when moving Serial connecting rod so as to rotate about the axis of shaft link times the link in the direction pulling the wire by rotating, characterized in that it is connected to the link.

  According to the present invention, when the operation lever that is rotatably supported on the vehicle body is operated via the first support shaft, the link that is connected to the operation lever via the link rotation shaft is the first support shaft. Since it rotates around the axis of the link rotation shaft that rotates around the axis of the link and pulls the wire connected to the link, compared to the wire that is directly connected to the other end of the operation lever, The pulling stroke of the wire can be amplified by the amount of rotation of the link. Accordingly, it is possible to increase the operation efficiency without increasing the ratio of the wire pulling stroke to the operation stroke of the operation lever and setting the length between the first rotation shaft and the operation portion of the operation lever short.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below based on one embodiment of the present invention shown in the accompanying drawings.

  1 to 6 show an embodiment of the present invention. FIG. 1 is a perspective view of an instrument panel when a parking brake operating lever is in a non-operating state, and FIG. 2 is a front view of FIG. 3 is a perspective view corresponding to FIG. 1 in a state in which the parking brake operation lever is operated, FIG. 4 is a sectional view taken along line 4-4 of FIG. 2, and FIG. FIG. 6 is a sectional view taken along line 6-6 of FIG.

  1 to 3, a console box 2 is provided at the center of the instrument panel 1 of the vehicle. The console box 2 includes a car navigation display 3, an air-conditioning blow grill 4, an audio device 5, and the like. The accessory case 6 etc. is equipped. An operation lever 10 for a parking brake is disposed on the side edge of the console box 2 on the driver's seat side (the right edge in FIGS. 1 to 3).

  The operation lever 10 has an operation portion 10a on one end side for a vehicle driver to hold and operate, and the operation portion 10a is provided in a recess 11 formed on a side edge portion on the driver seat side of the console box 2. It can be rotated between a non-operating position (position shown in FIG. 1 and FIG. 2) in which it is accommodated and an operating position (position shown in FIG. 3) in which the operating portion 10a is escaped from the recess 11.

  4 and 5 together, the operation lever 10 covers a lever body 12 formed in a hollow shape by a steel plate, and at least a portion of the lever body 12 exposed to the outside from the instrument panel 1. The lever body 12 partially penetrates through the front wall of the console box 2 and enters the console box 2. On the other hand, the vehicle body B has a support frame 7 that supports the instrument panel 1, and a bracket 14 fixed to the support frame 7 has a middle portion in the lever main body 12 of the operation lever 10 as a first support. It is rotatably supported via a shaft 15.

  A fan-shaped ratchet gear 17 and an arcuate surface 18 connected to one end of the ratchet gear 17 are formed on the bracket 14 so as to be arranged on a virtual arc centered on the first support shaft 15. On the other hand, a ratchet pole 19 having a claw portion 19a at one end is rotatably attached to the lever body 12 via a shaft 20 parallel to the first support shaft 15, and the claw portion 19a is connected to the operation lever 10. 4 is in contact with the circular arc surface 18 as shown in FIG. 4, and is engaged with one of the ratchet gears 17 as shown in FIG.

  One end of a connecting rod 21 accommodated in the lever body 12 is rotatably connected to the other end portion of the ratchet pole 19, and a flange portion 21 a provided at the other end of the connecting rod 21 and one end of the lever body 12.

In this way, they are linked and connected.

  Thus, at the other end of the operation lever 10, a link 28 is rotatably connected to the lever body 12 via a link rotation shaft 29 parallel to the first support shaft 15, and is offset from the link rotation shaft 29. The wire 26 is connected to the link 28 at the position where the connecting rod 31 is rotatably supported at one end on the support frame 7 of the vehicle body B via a second support shaft 30 parallel to the first support shaft 15. The other end is connected to the link 28 via the connecting shaft 32.

  Moreover, the link 28 is formed in a triangular shape, and the connecting point of the link rotating shaft 29, the connecting shaft 32, and the wire 26 to the link 28 is offset from each other at each apex portion of the triangle. Be placed. Further, the connecting rod 31 rotates the connecting rod 31 around the axis of the second support shaft 30 when the operation lever 10 rotates according to the operation from the non-operating position to the operating position by the vehicle driver. The link 28 is connected to the link 28 so as to rotate around the axis of the link rotation shaft 29 in the pulling direction.

  Next, the operation of this embodiment will be described. The intermediate portion of the operation lever 10 having the operation portion 10a on one end side is supported on the bracket 14 fixed to the vehicle body B through the first support shaft 15 so as to be rotatable. The link 28 is rotatably connected to the other end of the operation lever 10 via a link rotation shaft 29 parallel to the first support shaft 15, and the link 28 is offset from the link rotation shaft 29. Is connected to a wire 26 for operating the wheel brake 27 to the parking brake state. Moreover, the other end of the connecting rod 31 whose one end is rotatably supported on the support frame 7 of the vehicle body B via the second support shaft 30 parallel to the first support shaft 15 is operated by the vehicle driver. Accordingly, when the operating lever 10 rotates from the non-operating position to the operating position, the connecting rod 31 rotates about the axis of the second support shaft 30 to pull the link 26 in the direction in which the wire 26 is pulled. It is connected to the link 28 so as to rotate about the axis 29.

  Therefore, when the operating lever 10 is rotated from the non-operating position to the operating position, the link 28 rotates around the axis of the first support shaft 15 from the state indicated by the chain line in FIG. In this embodiment, the wire 26 that rotates and rotates around the axis of the rotation shaft 29 and is connected to the link 28 is pulled substantially linearly, and the wire 26 is directly connected to the other end of the operation lever 10.
