Description

[Detailed Description of the Invention] This invention relates to a wiring structure for a shift operating lever of an automobile, which is equipped with a switch in a gripping head.

Conventionally, in this type of vehicle, for example, a vehicle that can switch between two-wheel and four-wheel drive (hereinafter referred to as a four-wheel drive vehicle), as exemplified in Japanese Utility Model Application No. 56-6630, a shift operation mechanism is Since the connected gear shift operation lever and the drive wheel switching operation lever are installed separately, the quick response between the gear shift operation and the drive wheel switching operation is poor, making it difficult to use as a four-wheel drive vehicle. It was not possible to fully utilize the driving performance of the vehicle.

Therefore, this invention has been developed to change the drive wheels of a four-wheel drive vehicle equipped with an automatic transmission, for example, by a switching operation, and to operate the changeover switch using a grip head attached to the tip of a shaft constituting a speed change operation lever. The purpose is to improve operability and quick response, and to increase the protective effect of the harness by incorporating it into the switch and by making improvements to the wiring of the harness connected to the switch. .

Hereinafter, this invention will be explained in detail based on the illustrated embodiment. As shown in FIG. This is a connected gear shift operation lever. The shift operation lever 1 consists of a cylindrical shaft 2 whose outer peripheral surface except for the upper and lower ends is covered and protected by a contraction tube 21, and a grip head 3 attached to the tip 2a of the shaft 2. The lower end portion 2b of the shaft 2 is fixed via a bracket 4 to a rotating shaft 102 which is pivotally supported by a control plate 103 attached to a boot portion 101 on a base 100 installed on the indoor floor of the vehicle body. It is rotatable in the front and rear directions about the rotation shaft 102. Further, as shown in FIG. 2, the head section 3 is fixed by inserting the tip end 2a of the shaft 2 into an insertion hole 31 provided at the lower end and fixing it with a screw 5. In other words, the select knob 6 protrudes from the position corresponding to the thumb of the hand H in the gripping state. The base portion 6a of the select knob 6 is connected to the head portion 3.
The spring 7 is inserted into the insertion hole 32 inside the spring 7.
A tapered surface portion 61 is formed in a portion corresponding to the tip end portion 2a of the shaft 2, and the tapered surface portion 61 has a vertically movable portion within the shaft 2. The tip 8a of the rod 8, which is freely inserted, is facing.
A lock pin 9 is protruded from the lower end 8b of the rod 8, and the lock pin 9 is inserted into an engagement groove 104 of a control plate 103 for controlling the shift position in stages, which is arranged on the base 100. When the select knob 6 is pushed in, the tapered surface portion 61 presses against the rod tip 8a, causing the rod 8 to move downward against the biasing force of the spring 10, thereby engaging the engagement groove 104. While releasing the locked state and allowing the shaft 2 to rotate freely, the rod 8 is moved upward by opening the select knob 6 at a predetermined shift position and is locked in the engagement groove 104, thereby changing the shaft 2. It has a configuration that restricts the rotation of the.

Further, numeral 11 in the figure is a drive wheel changeover switch box having a knob 11a. The switch box 11 is located below and in parallel with the select knob 6 disposed on the head section 3, and is disposed within the operational range of the thumb of the hand H that grips the head section 3. It is inserted from the outside into a mounting hole 33 that communicates with the shaft insertion hole 31 formed in the head portion 3, and as shown in FIG. 33a
Due to the elastic action of an arcuate plate spring 12 provided in the holder, the holder is held in a detachable manner under pressure.

In addition, reference numeral 13 in the figure is a harness connected to the changeover switch box 11, and as shown in FIG. The part thereof is covered and held by the contraction tube 21.
As shown in FIG. 5, one end 13a of the harness 13 is pulled out from the distal end 2a of the shaft 2 through the mounting hole 33 of the switchbox 11 in the head section 3 so as to face the outside. After connecting to the terminal portion 11b, the switch box 11 is inserted into the mounting hole 33 while rotating the head portion 3 around the shaft axis with the head portion 3 in the unfixed state, and at the same time, one end side 13a of the harness 13 is inserted into the sixth As shown in the figure, the head portion 3 is rolled up along the circumferential direction of the outer periphery of the tip portion 2a of the shaft 2, and the head portion 3 is screwed into the screw 5 while maintaining a slight slack (looseness that does not sag).
It has a wiring structure fixed by.

Furthermore, the other end side 13b of the harness 13 pulled out from the lower end 2b side of the shaft 2,
As shown in FIG. 7, two through holes 101a and 101 are formed in the boot portion 101 on the base 100
The ring 1 is held by being threaded between the holes 1 and 1, and is left loose in the middle of being pulled out.
4 serves as a spacer between it and other mechanisms.

In the above embodiments, the shift control lever is of a type used in an automobile having an automatic transmission. However, the present invention is not limited thereto. In addition, the switches mounted on the head section are not limited to the drive wheel changeover switch in a four-wheel drive vehicle, but other switches such as a headlamp changeover switch may also be provided, and their mounting positions are controlled by the thumb. It is not limited to the active range, but can also be appropriately placed in the active range of other fingers.

As explained above, this invention has its lower end fixed to a rotating shaft that is linked to the speed change operation mechanism of the vehicle body, which is pivotally supported by the boot part of the base, and is rotatable back and forth around the rotating shaft. a shaft, a gripping head inserted into the tip of the shaft and housing a suitable switchbox; one end connected to the terminal of the switchbox stored in the head; a harness attached to a concave groove formed along the axial direction of the outer surface of the shaft and held and fixed by a contraction tube covered on the outer peripheral surface of the shaft, the other end of the harness being pulled out to the lower end side of the shaft; It is characterized in that the side of the boot part is threaded through at least two through holes provided through the boot part to provide slack, and an elastic ring is attached to the slack part. This allows the harness to follow the rotational movement of the shaft during gear shifting operations without straining the harness, and the attachment of the elastic ring prevents direct contact with the mechanism, preventing damage to the harness. This has excellent practical effects, such as being able to reliably prevent damage.
