TECHNICAL FIELD OF THE INVENTION
The present invention relates to a key interlock cable routing structure applied to an automobile equipped with an automatic transmission.
[0002]
[Prior art]
An automatic transmission mounted on a vehicle selects a shift position by tilting a shift lever (select lever) in the front-rear direction of the vehicle. A general arrangement of shift positions is P, R, N, D, 2, L (1) from the front. When the position of the shift lever is selected to any one of these positions, by associating this movement with the operation of the ignition switch of the engine, erroneous operation and erroneous starting can be prevented.
[0003]
Therefore, unless the brake pedal is depressed, the shift lever cannot be moved from the P (parking) position to another position, and the ignition key cannot be removed when the shift lever is at a position other than P. A key interlock device will be adopted (see Japanese Patent Application Laid-Open No. 4-244427 for the key interlock device and Japanese Patent Publication No. 3-53135 for a lock device for the shift lever and the handle).
[0004]
In order to equip this key interlock device, the shift lever mechanism and the ignition switch mechanism are linked by a key interlock cable composed of a double cable. Therefore, one end of the inner cable of the key interlock cable is connected to the shift lever or a member that moves integrally with the shift lever (rotation about the rotation fulcrum axis of the shift lever), and the other end of the inner cable is connected to the brake mechanism. As well as an ignition switch mechanism.
[0005]
The shift lever is often provided on the center console located between the driver's seat and the passenger's seat, and the ignition switch mechanism is located forward of it.Therefore, this key interlock cable has a bent middle part. Will be used.
[0006]
For this reason, in a small vehicle having a small space, the radius of curvature of the bent portion of the key interlock cable becomes small, and it has been difficult to obtain a smooth operation. Therefore, the key interlock cable is made longer than necessary to increase the radius of curvature as much as possible to obtain a smooth operation. However, with the conventional structure described below, it was difficult to route the key interlock cable in front of the vehicle.
[0007]
This will be described with reference to FIG. Reference numeral 1 denotes a shift lever, the lower end of which is welded to and supported by a shaft 5 inserted into a bracket 4 integrated with a substrate 3 mounted on the vehicle body 2. It is something that leans on. Reference numeral 6 denotes a grip, and 7 denotes a button provided on the grip 6. The middle portion of the shift lever 1 penetrates the indicator panel 8, and the lower part of the indicator panel 8 is made invisible by a console box 9 that covers the indicator panel 8 and its periphery.
[0008]
A detent pin 10 protrudes horizontally from the shift lever 1, penetrates a detent hole 12 (see FIG. 1) of a detent plate 11, engages with a predetermined step, and holds a shift position. I have. A shift cable 13 has a front end connected to the shift lever 1 and a rear end (not shown) connected to the transmission.
[0009]
A key lock plate 14 is provided in parallel adjacent to the detent plate 11, and is supported so as to be rotatable about a shaft 15. The key lock plate 14 is provided with a notch 14a in a part thereof. When the detent pin 10 is engaged with the notch 14a, the shift lever 1 and the key lock plate 14 are linked, and the button 7 of the grip 6 is By pressing, the key lock plate 14 is rotated in the direction of the arrow.
[0010]
At a part of the key lock plate 14 opposite to the engagement position of the detent pin 10 with the shaft 15 interposed therebetween (the front side of the vehicle), the tip of the inner cable 17 of the key interlock cable 16 composed of a double cable is provided. The attached boss 18 is mounted on a shaft 19. The outer cable 20 of the key interlock cable 16 is held by a bracket 22 fixed to the detent plate 11 with a nut 21.
[0011]
[Problems to be solved by the invention]
In the conventional structure having such a configuration, since the key interlock cable 16 is directed obliquely downward in front of the vehicle, the key interlock cable 16 is bent largely once toward the rear and is directed forward along the side of the vehicle body. Searching was impossible. For this reason, there is a problem in that the layout of the parts is restricted, and in connection with this, the number of work steps for wiring increases.
[0012]
Japanese Unexamined Utility Model Publication No. 1-173814 discloses a prior art in which a wire rod for connecting a lever and a lever is divided into two parts, and their divided ends are arranged in parallel and connected by a connecting bracket. According to this invention, the wiring direction can be easily changed by dividing the wire rod into two parts, but there is a problem that the working direction (moving direction) of the wire rod is reversed from the middle part.
[0013]
The present invention has been made in view of this point, and by interposing a conversion device that changes the moving direction of the key interlock cable, it is possible to route cables even in a state where space is restricted, Moreover, it is an object of the present invention to provide a key interlock cable routing structure that allows the cable to be taken out in a direction that matches the intended purpose.
[0014]
[Means for Solving the Problems]
According to the present invention, as a means for solving the above-mentioned problem, in the invention described in claim 1, the key lock plate is rotated by engagement of a detent pin that projects horizontally from the shift lever, and the key lock plate is turned. In a key interlock device in which a key interlock cable is moved by movement, a lower end of the shift lever is supported on a shaft inserted into a bracket integrated with a board attached to a vehicle body, and the key interlock cable is moved back and forth. A switching device for moving the key in a direction, a rod having one end connected to a part of the key lock plate, and a vertical lever having an upper end connected to the other end of the rod. It is between the lock plate and said key interlock cable disposed in the vehicle front than the shaft, connected at the lower edge of the lever The key interlock cable is routed from the front to the rear of the vehicle on the board, and a conversion device that changes the moving direction of the key interlock cable in a horizontal plane is provided on the board on the vehicle rear side from the axis. It is characterized by being arranged.
[0015]
According to a second aspect of the present invention, in the first aspect, the conversion device for changing the moving direction of the key interlock cable in a horizontal plane is an outer casing having a partially arcuate portion. It is characterized by.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
In the following, an embodiment of the present invention will be described with reference to FIG. The major feature of this mechanism is that the inner cable 17 of the key interlock cable 16 is not directly connected to the key lock plate 14, and the lower end of a substantially I-shaped vertically extending lever 24 pivotally attached to the detent plate 11 with a shaft 23. Is mounted on the shaft 25. A rod 26 and a boss 27 are connected between the upper end of the lever 24 and a part of the key lock plate 14.
[0017]
The rod 26 and the boss 27 may be integrated, but the length may be changed by means such as screwing. Reference numeral 28 denotes a shaft for attaching the rod 26 to the lever 24.
The conversion device for moving the key interlock cable 16 in the front-rear direction includes a rod 26 having one end connected to a part of the key lock plate 14 and a lever 24 having an upper end connected to the other end of the rod 26. Is done.
[0018]
The outer cable 20 of the key interlock cable 16 is held by an outer casing 30 fixed to the detent plate 11 with a nut 29. The outer casing 30 has an arcuate portion in a part thereof as described later, and constitutes a conversion device for changing the moving direction of the key interlock cable 16 in a horizontal plane.
[0019]
The outer casing 30 will be described with reference to FIG. 2 showing a plan view, FIG. 3 showing a front view, and FIG. 4 showing a XX section of FIG. The outer casing 30 has a cylindrical portion 31 and a plate portion 32 integrally formed. The cylindrical portion 31 is formed by a straight portion 31a in a range indicated by A in FIG. 2 and an arc-shaped portion 31b in a range indicated by B in FIG. Has become. The plate portion 32 is a portion for fixing the entire outer casing 30 to the detent plate 11 with bolts 29.
[0020]
The key interlock cable 16 is inserted through the cylindrical portion 31 of the outer casing 30. Since a bendable double cable is used as the key interlock cable 16, when the tubular portion 31 of the outer casing 30 is inserted, the cable is bent by the arcuate portion 31b and held in that state. Therefore, as shown in FIG. 5, the tip of the vehicle can be routed in a circular arc below the driver's seat 33, and can be routed so that the tip faces forward of the vehicle body.
[0021]
In this device configured as described above, when the driver grips the grip 6 and tilts the shift lever 1, the detent pin 10 engaged with the notch 14a of the key lock plate 14 is pressed by pressing the button 7. The key lock plate 14 is rotated in the direction of the arrow in FIG. This movement is transmitted to the lever 24 via the boss 27 and the rod 26, and is rotated clockwise about the shaft 23.

【The invention's effect】
The present invention is a wiring structure of a key interlock cable configured as described above, in which a lower end of a shift lever is supported by a shaft inserted through a bracket integrated with a board attached to a vehicle body, and a key interlock is provided. A conversion device for moving the cable in the front-rear direction includes a rod having one end connected to a part of the key lock plate, and a vertical lever having an upper end connected to the other end of the rod . It is arranged between the key lock plate and the key interlock cable, in front of the vehicle with respect to the shaft , and the key interlock cable connected to the lower end of the lever is routed on the board from the front to the rear of the vehicle, Since the conversion device that changes the direction of movement of the key interlock cable in the horizontal plane is provided on the board on the vehicle rear side from the shaft, the key interlock cable is not used. It is possible to bend without once bent largely toward the rear, it has become possible to perform the wiring as directed forward along a vehicle body side. For this reason, a degree of freedom is generated in the layout of parts, and in connection with this, the number of work steps for wiring can be reduced.
[0024]
A conversion device for moving the key interlock cable in the front-rear direction includes a rod having one end connected to a part of the key lock plate, and a vertical lever having an upper end connected to the other end of the rod. Therefore, the structure is simple, and there is no adverse effect such that the operation direction is reversed from the intermediate portion.
[0025]
Further, since the conversion device for changing the moving direction of the key interlock cable in a horizontal plane is an outer casing having an arcuate portion in part, the key interlock cable is only inserted through the cylindrical portion, so that the key interlock cable is inserted. There is an advantage that the direction of the lock cable can be freely changed and the cable can be easily routed in a desired direction.
