Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an ignition control device for a simulation vehicle of a four-wheeled motor vehicle.

(Prior art) During automatic or semi-automatic endurance driving by a simulation vehicle for a four-wheeled motor vehicle, the ignition on, off, and start control is performed by pulling out a connector in the middle of the vehicle's ignition circuit and using the simulation It is connected to the connector of the ignition control circuit of the device, and is controlled by electrical ignition on/off and start commands from the simulation device.

(Problems to be solved by the invention) In the conventional device, the ignition circuit is reconnected at the connector part, and if a contact failure occurs in the connector part during endurance operation, the ignition is turned off, but the vehicle is not driven. Since the system is in a rotating state, raw gas flows into the catalyzer due to the pumping action of the engine, causing abnormal heating and damage to the catalyzer.

(Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, a fixing member is attached to the ignition key box via a gripping member that grips it, and a servo motor for rotating the key is attached to the fixing member. A supporting plate is attached to the servo motor via an adjustment member, and a key actuation member having a key holding groove for holding a key inserted into the key box is attached to the servo motor. The key is adjustable by an adjustment member, and the key is rotated to the on/off and start positions of the ignition by rotation of the servo motor based on commands from the simulation device.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. Figures 1 to 5 show an embodiment of the present invention. Figure 1 is a plan view showing how the ignition control device according to the present invention is used, and Figure 2 shows the procedure for installing the ignition control device. A partially cutaway plan view, FIG. 3 is a front view showing the key control part of this device, FIG. 4 is a front view showing the fixed part of this device, and FIG. 5 is a side view of the key control part shown in FIG. 3. It is a diagram.

As shown in FIG. 1, this device consists of a fixing member 2 attached to a key box 1 after removing a steering cover A, an adjusting member 3 extending from the fixing member 2 in a substantially L-shape, and an adjusting member 3 extending horizontally from the adjusting member 3. The servo motor 5 is inserted into the key insertion hole 1 through the supporting plate 4
It is arranged and fixed so as to face above the key 6 inserted into the key 1. The second one shows this in detail.
5 to 5. FIG. The fixing member 2 is symmetrical and can be divided into two gripping members 21 and 22, each having an arm bending recess 23 for gripping the key box 1 on opposing surfaces of the distal ends thereof. A base cylinder 31 of the adjusting member 3 for adjusting the gap between the support plate 4 and the fixing member 2 is fixedly provided. Both gripping members 21 and 22 have a bush 24 that is press-fitted into one gripping member 22 and has a screw hole 24a inside thereof on the proximal end side of the arm bent recesses 23 and 23, and a bush 24 that is press-fitted into one gripping member 22 and has a screw hole 24a inside, and a bush 24 that is fitted into the screw hole 24a of the bush 24. Gripping member 21
It is connected by a bolt 25 that is inserted and screwed from the side. Further, the gripping members 21 and 22 have a stopper 27 inserted into a through hole 26 which is bored in the length direction of one of the gripping members 21 and whose intermediate portion is open at the distal end side of the arm bending recesses 23 and 23. The stopper 27 is connected by a screw hole 28 bored perpendicularly to the length direction of the stopper 27 and a bolt 29 inserted from the other gripping member 22 and screwed into the screw hole 28.
By tightening 9, both gripping members 21 and 22 are crimped and fixed to the body of the key box 1.

The adjustment member 3 consists of a base tube 31 that is bent in a substantially L-shape and extends from the fixing member 2, an adjustment nut 34 that is covered on top of this, and an adjustment bolt 38 that extends to the support plate 4. It is something. The base cylinder 3
1 has an open upper part, a hole 32 formed inside, and a circumferential groove 33 formed above the outer circumferential surface. On the other hand, the adjustment nut 34 covered over the opening surface of the base cylinder 31 has a screw hole 35 having a slightly smaller diameter than the hole 32 of the base cylinder 31 so that the central axis thereof coincides with the hole 32, and A plurality of screw holes 36 are bored in the surface, and the tip of a screw 37 screwed into the hole is engaged with the circumferential groove 33, and the adjustment nut 34 is inserted into the base cylinder 3.
It is rotatably arranged above 1.

On the other hand, the adjustment bolt 38 is threaded into the screw hole 35 of the adjustment nut 34, and forms a cylindrical piece 39 having a hole 39a at its upper end.

The support plate 4 is formed with a cylindrical piece 41 corresponding to the cylindrical piece 39, and the cylindrical piece 41 is also provided with a hole 41a having the same diameter as the hole 39a, and a bolt passes through the hole 39a, 41a. 4
2 and nuts 43, the support plate 4 is fixed to the adjustment bolt 38 so as to have a substantially L-shape in plan. A servo motor 5 is attached to the support plate 4 and is operated by a command from a simulation circuit (not shown).A grip portion 61 at the top of the key 6 is attached to the tip of a rotating shaft 51 of the servo motor 5.
A key operating member 7 having a substantially U-shaped cross section and having a key holding groove 71 for inserting and holding the key is fixedly provided.

To explain the installation of this device configured as above and the ignition operation using this device, first remove the steering cover A of the vehicle body to expose the key box 1, and fix the grip members 21 and 22 of the fixing member 2 to the body of the key box 1. do. At this time, the fixing member 2 and the servo motor 5 are separated from each other.

Next, the base cylinder 3 of the adjustment member 3 connected to the fixed member 2
An adjustment bolt 38 connected to the support plate 4 that supports the servo motor 5 is inserted into the hole 32 provided in the servo motor 1. This insertion is performed by screwing the adjustment bolt 38 into the screw hole 35 of the adjustment nut 34 provided at the top of the base cylinder 31, and after these two are screwed together, the adjustment nut 34 is rotated to make the adjustment. The insertion depth of the bolt 38 is adjusted. That is, the above-mentioned screwing operation positions the servo motor 5 with respect to the key box 1, so that the key 6 is held in the key holding groove 71 of the key operating member 7 provided at the tip of the rotating shaft 51 of the servo motor 5. The section 61 is inserted and held.

In this state, the servo motor 5 rotates in response to a command from the aforementioned simulation device (not shown), thereby rotating the key 6 held by the key operating member 7 to the desired on, off, and start positions.

(Effects of the invention) As described above, the present invention has a structure in which the key is rotated by a servo motor, so there is no need to reconnect the wiring as in the conventional case, and even if there is a contact failure in the power supply circuit to the servo motor while driving. Even if power is not supplied due to a problem such as this, the key is held in the on position, so the inhaled raw gas continues to be burned, thereby preventing abnormal heating or damage to the catalyzer.
