Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle driving robot on a chassis dynamometer.

[0002]

[Prior art]

 Conventionally, in order to test the dynamic driving performance of automobiles, a chassis dynamometer has been used to perform a simulated driving of an actual vehicle. Recently, this simulated driving of an actual vehicle is driven by hydraulic pressure, air pressure, or a DC motor. A vehicle driving robot (hereinafter simply referred to as a driving robot) that can operate multiple actuators individually and use this actuator to depress the accelerator pedal, brake pedal, clutch pedal, etc. and switch the shift lever will be used. Is becoming.

In order to drive an automobile to be tested in a predetermined traveling pattern by such a driving robot, actuators for operating the pedals and shift levers, respectively, are firmly attached to the robot body, The operating state of each pedal or shift lever is created manually, the operating robot stores the operation amount and coordinates for operating each pedal or shift lever, and each actuator is controlled using the coordinates during the test operation. Need to be made.

By the way, the driving robot is provided on a driver's seat of an automobile by an appropriate supporting member by facing each actuator so as to correspond to each pedal or shift lever of the automobile. For accelerator pedals, brake pedals, and clutch pedals, the actuators that depress these pedals are arranged in a state of being separated from each pedal, and each actuator depresses the pedal by expanding and contracting its actuator shaft. However, since it is configured to move, return, or move away from the pedal, it is necessary to ensure proper alignment of each actuator shaft (actuator shaft) with each pedal.

In the past, the position adjustment was performed by extending or contracting the actuator shaft by a remote controller or manually.

[0006]

[Problems to be solved by the device]

 However, in the alignment method as described above, it is not possible to align the two unless the tip of each actuator shaft is extended until it comes into contact with each pedal. Since it is installed in a place where there is no such movement, it is difficult to reliably observe the movement of the actuator shaft, and as a result, it takes a lot of time and effort to align each actuator shaft with each pedal, and the accuracy of this alignment is not always required. It wasn't enough.

The present invention has been made in view of the above matters, and an object thereof is to easily and securely align the shaft of the actuator with respect to the pedal without expanding and contracting the shaft of the actuator. It is to provide a driving robot capable of

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a driving robot in which an actuator for operating each pedal of an accelerator, a brake, and a clutch is provided in a robot body mounted on a driver's seat. It is characterized in that an LED is provided at the tip of the shaft.

[0009]

[Action]

 The LED provided at the tip of the actuator shaft illuminates the pedal facing the actuator shaft, and by visually observing the position of the irradiation portion on the pedal surface, it is possible to confirm whether or not the actuator shaft is touching the core. Therefore, the actuator shaft can be easily and surely aligned with the pedal without expanding and contracting the actuator shaft.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the present invention. First, in FIGS. 1 and 2, reference numeral 1 denotes a robot body, which is attached to a base 3 placed on an operation seat 2 and To the front (to the right in FIGS. 1 and 2), an accelerator pedal actuator 7, a brake pedal actuator 8 and a clutch for pedaling the accelerator pedal 4, brake pedal 5 and clutch pedal 6 provided on the vehicle, respectively. A pedal actuator 9 is provided. Although the shift lever actuator is also provided in the robot body 1, it is not shown in the figure because it is not relevant in the present application.

Since the pedal actuators 7, 8 and 9 have the same structure and the same mounting structure, the accelerator pedal actuator 7 is representatively used as an example and the structure and the mounting structure are shown in FIG. Refer to also for explanation. The accelerator pedal actuator 7 comprises an actuator shaft 7a which is reciprocated by a servomotor (not shown) provided on a support member 7b, and is attached to the robot body 1 as follows. . 1 to 3, the reference numerals of the brake pedal actuator 8 and the clutch pedal actuator 9 are the same as those of the accelerator pedal actuator 7, for example, the brake pedal actuator 8 The reference numeral 8a attached in indicates that the member is the same as the actuator shaft 7a in the accelerator pedal actuator 7.

That is, a support shaft 10 and a screw shaft 12 rotated by a handle 11 are provided in parallel to each other in the left-right direction in front of the robot body 1 (on the side of the pedals 4, 5, 6). . Reference numeral 13 denotes a slide base that is loosely fitted to the support shaft 10 and held by being screwed into the screw shaft 12 so as to be slidable in the left-right direction. Reference numeral 14 denotes an eccentric cam having a claw 15 that engages with the thread groove of the screw shaft 12. When the handle 16 is operated so as to be perpendicular to the screw shaft 12, the claw 15 engages with the thread groove. Rotation of the screw shaft 12 is allowed, and in this state, when the handle 11 is turned clockwise, the slide base 13 moves in the direction of arrow A, and when the handle 11 is turned counterclockwise, the slide base 13 moves in the direction of arrow B. Move to. Then, when the handle 11 is set in a slightly inclined state as shown in FIGS. 2 and 3, the rotation of the screw shaft 12 is locked.

Reference numeral 17 denotes an actuator mounting base that is pivotally supported above and forward of the slide base, and a support member 7b of the accelerator pedal actuator 7 is fixed to the front side of the actuator mounting base by an appropriate means. 18 is a screw shaft for adjusting the standing posture of the actuator mounting base 17, and the lower end thereof is rotated to a receiving member 20 pivotally supported by a bracket 19 mounted on the upper surface of the slide base 13 on the back side of the actuator mounting base 17. It is movably held, has a handle 21 at the upper end, and is screwed with a nut member 23 held by a bracket 22 standing upright on the rear surface of the actuator mounting base 17. When the handle 21 is turned clockwise when viewed from above, the nut member 23 rises in the direction of arrow C, the actuator mounting base 17 tilts forward, and when turned counterclockwise, the nut member 23 moves in the direction of arrow D. The actuator mounting base 17 descends and tilts backward.

That is, in the accelerator pedal actuator 7, the positional relationship of the actuator shaft 7a with respect to the accelerator pedal 4 can be adjusted by operating the handles 11 and 21. The other brake pedal actuator 8 and the clutch pedal actuator 9 can be adjusted in the same manner, and the actuators 7, 8 and 9 can be adjusted independently of the other actuators. You can

In order to facilitate the position adjustment, the present invention is configured as follows. That is, as shown in an enlarged manner in FIG. 4, for example, a commercially available LE D24 with a lens is embedded in the front end surface of the shaft tip portion 7c of the actuator shaft 7a of the accelerator pedal actuator 7, and the LED 24 is used to drive the accelerator pedal 4 It is possible to irradiate in spots. In addition, 25 is a lead wire for power supply.

In the driving robot thus configured, for example, when the actuator shaft 7a of the accelerator pedal actuator 7 is aligned with the corresponding accelerator pedal 4, as shown in FIGS. The LED 24 is caused to emit light, and the light 26 is applied to the accelerator pedal 4. Since the light 26 at this time is spot light, the positional relationship of the actuator shaft 7a of the accelerator pedal actuator 7 with respect to the accelerator pedal 4 can be grasped only by visually observing the irradiation position of the light 26 on the accelerator pedal 4. it can. When the positional relationship is not a predetermined positional relationship, the handle 11 or 21 is appropriately operated to adjust the position of the accelerator pedal actuator 7.

In the adjustment, unlike the conventional case, it is not necessary to extend and retract the actuator shaft 7a by a remote controller or manually, and since the surroundings are illuminated by the light 26 emitted from the LED 24, the actuator shaft 7a can be adjusted. When you check the movement by expanding and contracting, there is an advantage that you can observe this, and workability in a dim place is greatly improved.

It goes without saying that the other brake pedal actuators 8 and clutch pedal actuators 9 can be adjusted in the same manner.

The present invention is not limited to the above-described embodiment. For example, as shown in FIG. 5, a plurality of LEDs 24 may be embedded in a ring shape on the front end surface of the shaft tip portion 7c of the actuator shaft 7a. Good.

[0021]

[Effect of device]

 As described above, according to the present invention, the LED provided at the tip of the actuator shaft illuminates the pedal facing the actuator shaft, and the position of the illuminating portion on the pedal surface is visually checked to determine the position of the actuator shaft. You can check whether or not you are touching. Therefore, the actuator shaft can be easily and surely aligned with the pedal without expanding and contracting the actuator shaft.

Since the surroundings are illuminated by the light emitted from the LED, there is an advantage in that when the operation is confirmed by expanding and contracting the actuator shaft, there is an advantage that this can be observed, and workability in a dim place is significantly improved. It Further, the LED used as the light emitting body has advantages that it is inexpensive and consumes less power.
