  A spring for applying a reaction force when the pedal is depressed is connected to the brake pedal of the automobile driving simulation device. The reaction force of the brake pedal of an automobile is set to various magnitudes depending on the vehicle type. For example, in a light vehicle, the reaction force of a brake pedal is set lightly. The reaction force of the brake pedal of the ordinary car is set larger than the reaction force of the brake pedal of the light car. Further, among ordinary cars, the reaction force of the brake pedal is individually set according to the manufacturer and the vehicle type. For example, the reaction force of a brake pedal in a foreign manufacturer's automobile tends to be larger than the reaction force of a brake pedal in a Japanese manufacturer's automobile.

  With reference to FIG. 1 to FIG. 6, a brake pedal device of an automobile driving simulation device in an embodiment will be described.

  FIG. 1 shows an automobile driving simulation apparatus according to the present embodiment. The vehicle driving simulation device 1 includes a driver seat 2, a handle 3, an accelerator pedal 5, and a brake pedal 11. The automobile driving simulation device 1 includes a display device 4 that displays a landscape that the driver can see through the windshield, and an arithmetic processing device that controls the display device 4. The display device 4 is disposed on the front side of the driver's seat. The arithmetic processing unit is configured by, for example, a digital computer. The arithmetic processing device stores in advance a database including images of landscapes such as roads and urban areas.

  The driver sits in the driver's seat 2 and performs the same operation as that of normal car driving. When the driver operates the handle 3, the accelerator pedal 5, the brake pedal 11, and the like disposed in the vicinity of the driver's seat 2, signals corresponding to these operation amounts are input to the arithmetic processing unit.

  The arithmetic processing unit detects the operation amount such as the depression amount of the accelerator pedal 5, the depression amount of the brake pedal 11, and the rotation amount of the handle 3, for example. The arithmetic processing unit calculates the movement of the automobile based on these manipulated variables. Then, the arithmetic processing device refers to a landscape database stored in advance, and calculates an image of the landscape from the driver's seat corresponding to the motion of the automobile. Then, the arithmetic processing device displays an image obtained by the calculation on the display device 4. By using the automobile driving simulation apparatus 1, the driver can perform driving training and the like with the feeling of driving an actual car.

  In FIG. 2, the perspective view of the brake pedal apparatus in this Embodiment is shown. FIG. 3 shows a front view of the brake pedal device in the present embodiment. 2 and 3, the brake pedal device 10 includes a base member 16 that supports the brake pedal 11 so as to be swingable. The base member 16 includes a base plate 16a formed in a plate shape, and a chassis 16b standing from the base plate 16a. The brake pedal 11 has an arm 12 as a swinging member supported by the base member 16 and a stepping plate 13 fixed to the tip of the arm 12. The arm 12 of the present embodiment is formed in a plate shape. The arm 12 swings about the axis of the rotary shaft 15 supported by the chassis 16b as the center of rotation.

  A potentiometer 17 is connected to the rotary shaft 15. The potentiometer 17 detects the depression amount when the driver depresses the brake pedal 11. More specifically, the potentiometer 17 is formed so as to detect the rotation angle of the rotary shaft 15. The detected rotation angle is sent to the arithmetic processing unit through the signal line 18.

  FIG. 4 shows an enlarged partial cross-sectional view of a portion for energizing the brake pedal of the brake pedal device in the present embodiment. 2 to 4, the brake pedal device 10 includes a first coil spring 22 as a first elastic member that biases the brake pedal 11. In the present embodiment, two coil springs 22 are arranged, and the arm 12 of the brake pedal 11 is biased.

  A shaft 27 is inserted into the coil spring 22. The shaft 27 is supported by the support member 23 via the cylindrical member 28. The support member 23 has a shaft portion 23a. The support member 23 is supported by the fixing member 25 by the shaft portion 23a. The support member 23 is formed to be rotatable about the axis of the shaft portion 23a as a rotation center. The fixing member 25 is fixed to the base plate 16a. A cylindrical member 28 is fixed to the support member 23. The cylindrical member 28 has a collar portion 28a formed in a plate shape. The shaft 27 is disposed so as to slide on the inner surface of the cylindrical member 28. Thus, as shown by the arrow 92, the shaft 27 and the coil spring 22 are formed to be rotatable around the shaft portion 23a.

  At one end portion of the shaft 27, a collar-shaped stopper portion 27a is formed. The stopper 27 a comes into contact with the support member 23, thereby preventing the shaft 27 from coming off the cylindrical member 28. When the stopper portion 27a comes into contact with the support member 23, the first coil spring 22 is in the most extended state in this arrangement.

  A first engagement member 21 connected to the arm 12 is fixed to the other end of the shaft 27. The coil spring 22 is disposed between the first engagement member 21 and the collar portion 28 a of the tubular member 28. The first engagement member 21 is disposed at the tip of the coil spring 22. The first coil spring 22 is formed to be extendable and contractible. When the brake pedal 11 is depressed, the first coil spring 22 provides the arm 12 with a reaction force against the depression force, as indicated by an arrow 93. A hole 21 a is formed in the first engagement member 21.

  The brake pedal device includes connection means for connecting the first coil spring 22 to the arm 12 of the brake pedal 11. The first coil spring 22 is connected to the arm 12 via the first engagement member 21. The connection means of the present embodiment includes an arm 12 having a plurality of holes 12a and a first engagement member 21 having a hole 21a. Further, the connecting means includes a ball lock pin 26 as a rod-like member that connects the engaging member 21 to the arm 12.

  The engagement member 21 is connected to the arm 12 by pushing the ball lock pin 26 as indicated by an arrow 91 with the positions of the hole 12a of the arm 12 and the hole 21a of the engagement member 21 being aligned. Can do.

  The ball lock pin 26 has a ball part 26a urged in the protruding direction at the tip part. By pushing the ball lock pin 26 into the hole portion 21 a, the ball portion 26 a is retracted, and the ball lock pin 26 can be inserted into the hole portion 21 a of the engagement member 21 and the hole portion 12 a of the arm 12. When the ball lock pin 26 is inserted to a predetermined depth, the ball portion 26a penetrates and the ball portion 26a protrudes. For this reason, it is possible to suppress the ball lock pin 26 from coming off.

  Similarly, when the ball lock pin 26 is pulled out, by pulling the ball lock pin 26, the ball portion 26a comes into contact with the hole portion 21a and moves backward. For this reason, the ball lock pin 26 can be easily pulled out.

  As described above, when the brake pedal 11 is depressed, the arm 12 swings about the axis of the rotary shaft 15 as the rotation center. At this time, the first engaging member 21 moves in a direction approaching the base plate 16a. The shaft 27 moves along the cylindrical member 28. The coil spring 22 contracts between the first engagement member 21 and the flange portion 28a. The coil spring 22 applies a reaction force to the brake pedal 11 as indicated by an arrow 93.

  The brake pedal device 10 according to the present embodiment includes a second coil spring 32 as a second elastic member that biases the brake pedal 11. The second coil spring 32 of the present embodiment is disposed above the first coil spring 22. A fixing portion 33 is formed on the base plate 16a. A cylindrical member 38 is fixed to the fixing portion 33. The second shaft 37 is supported by the cylindrical member 38. The second shaft 37 slides on the inner surface of the cylindrical member 38. On the second shaft 37, a collar-shaped stopper portion 37a is formed. When the stopper portion 37a contacts the fixed portion 33, the shaft 37 is prevented from popping out.

  A second engagement member 31 is connected to the end of the second shaft 37. The coil spring 32 is disposed between the second engagement member 31 and the fixed portion 33. The second engagement member 31 is connected to the arm 12 of the brake pedal 11 by a fixing pin 34. As described above, the second coil spring 32 is also connected to the arm 12 via the second engagement member 31.

  When the brake pedal 11 is depressed, the second engagement member 31 moves in a direction approaching the base plate 16a. The second shaft 37 moves along the cylindrical member 38. As the second coil spring 32 contracts, a reaction force can be applied to the brake pedal 11 as indicated by an arrow 94.

  Further, a stopper member 45 is disposed below the region where the first coil spring 22 is disposed. The stopper member 45 is formed from an elastic member. The stopper member 45 is made of rubber, for example. The stopper member 45 is fixed to the base plate 16 a of the base member 16. When the brake pedal 11 is strongly depressed, the arm 12 comes into contact with the stopper member 45 and the depression is prevented. That is, when the arm 12 comes into contact with the stopper member 45, the limit of swinging of the arm 12 is set.

  The total elastic force of the two first coil springs 22 of the present embodiment is formed to be smaller than the elastic force of the second coil spring 32. That is, the spring constant kB when the two coil springs 22 are regarded as one coil spring is formed smaller than the spring constant kA of the second coil spring 32. The spring constant of the first coil spring 22 and the spring constant of the second coil spring 32 can be set according to the required reaction force.

  By the way, the connection means for connecting the first coil spring 22 to the brake pedal 11 according to the present embodiment changes the rotation angle of the first coil spring 22 so that the coil spring 22 is connected to the brake pedal at a plurality of positions. 11 to be connectable. That is, the engaging member 21 is formed so as to be connectable to the arm 12 by changing the angle of the coil spring 22 in the direction in which the coil spring 22 extends and contracts with respect to the arm 12.

  With reference to FIG. 4, the plurality of holes 12 a of the arm 12 are arranged on an arc line 99 centering on the rotation axis of the coil spring 22. That is, the plurality of holes 12 a are formed so that the distance between each hole 12 a and the rotation shaft of the support member 23 is constant. And the arbitrary hole part 12a can be selected and the engagement member 21 can be connected.

  In FIG. 5, the side view explaining the 1st state of the brake pedal apparatus of this Embodiment is shown. In FIG. 6, the side view explaining the 2nd state of the brake pedal apparatus of this Embodiment is shown. In the first state shown in FIG. 5, the first engagement member 21 is connected to the lowermost hole 12 a formed in the arm 12. In the second state shown in FIG. 6, the first engagement member 21 is connected to the uppermost hole 12 a formed in the arm 12. In FIGS. 5 and 6, a state before the brake pedal is depressed is shown by a solid line, and a state when the brake pedal is depressed by a broken line. In the first state shown in FIG. 5, the reaction force against the brake pedal 11 is the largest. In the second state shown in FIG. 6, the reaction force against the brake pedal 11 is the smallest.

  Referring to FIG. 5, brake pedal 11 is depressed in the direction indicated by arrow 95 by the driver. Here, the force TA generated by the second coil spring 32, the spring constant kB when the two first coil springs 22 are regarded as one coil spring, and the free length of the first coil spring 22 are determined. A deformation amount SB is determined. Further, in the vertical direction, the distance XC from the rotation axis of the rotary shaft 15 to the point where the force of the stepping plate 13 acts and the biasing force of the second coil spring 32 from the rotation axis of the rotation shaft 15 act on the arm 12. A distance XA to the point and a distance XB from the rotation axis of the rotary shaft 15 to the point where the urging force of the first coil spring 22 acts on the arm 12 are determined. When these variables are used, the reaction force F supplied to the brake pedal is expressed by the following equation (1).

  F = (TA ・ XA + kB ・ SB ・ XB ・ sinθ) / XC (1)

  Here, the angle θ is an angle in a direction in which the first coil spring 22 extends (a direction in which the first coil spring 22 extends or contracts) with respect to the vertically downward direction. The angle θ corresponds to an angle α in the extending direction of the arm 12 with respect to the extending direction of the first coil spring 22.

  In the first state shown in FIG. 5, since the distance XB is large, the amount of contraction of the first coil spring 22 with respect to a predetermined stepping depth increases. Further, since the distance XB from the rotation axis of the rotation shaft 15 as the fulcrum to the position where the ball lock pin 26 as the action point is inserted is long, the reaction force becomes large. On the other hand, in the second state shown in FIG. 6, since the distance XB is small, the amount of contraction of the first coil spring 22 with respect to a predetermined depression depth is small. Further, since the distance XB from the rotation axis of the rotary shaft 15 as the fulcrum to the position where the ball lock pin 26 as the action point is inserted is short, the reaction force becomes small.

  In other words, referring to the above equation (1), the angle θ increases as the position of the hole 12a connecting the first engagement member 21 increases. The horizontal component of the urging force of the coil spring 22 in the direction shown by the arrow 93 becomes a reaction force in the stepping direction. For this reason, the reaction force decreases as the angle θ increases. That is, since the urging force is dispersed as the angle θ increases, the reaction force against the force that steps on the stepping plate 13 decreases.

  Thus, in the brake pedal device 10 of the present embodiment, the reaction force acting on the brake pedal 11 is increased as the hole 12a that connects the coil spring 22 via the engaging member 21 is located on the lower side. Can do. That is, the brake pedal 11 becomes heavier as the hole 12a connecting the engaging member 21 is located on the lower side. Thus, if the connection position of the hole 12a of the arm 12 is changed, the rotation angle of the first coil spring 22 can be changed. And the magnitude | size of the reaction force which acts on the brake pedal 11 can be changed easily by changing the position in which the ball lock pin 26 is inserted.

  FIG. 4 shows a state in which the ball lock pin 26 is removed, and the connection between the first engagement member 21 and the arm 12 is released. The first coil spring 22 and the second coil spring 32 are in the most extended state. The stopper portion 37 a is locked to the fixed portion 33, and the stopper portion 27 a is locked to the support member 23.

  The hole 12a of the arm 12 is formed so as to be able to be connected to the arm 12 by rotating the first coil spring 22 at the position of the brake pedal 11 where the second coil spring 32 extends most. Further, the hole 21 a of the first engagement member 21 is formed so as to overlap the hole 12 a of the arm 12 in the state where the first coil spring 22 is also extended most. Therefore, the driver can easily align the positions of the holes 12a and 21a by rotating the coil spring 22 with the ball lock pin 26 removed.

  For example, if the second coil spring 32 as the second elastic member is not disposed, the arm 12 hangs vertically downward when the connection between the first engagement member 21 and the arm 12 is released. It becomes difficult to align the portions 12a and 21a. Thus, by arranging the second elastic member, it is possible to easily align the holes 12a and 21a. In addition, the 2nd coil spring 32 as a 2nd elastic member does not need to be arrange | positioned.

  Further, the connecting means of the present embodiment includes the arm 12 in which a plurality of holes 12a are formed, the first engagement member 21 in which the holes 21a are formed, the hole 12a of the arm 12 and the engagement members. And a ball lock pin 26 that is inserted through the hole 21 a of the member 21 and connects the engaging member 21 to the arm 12. With this configuration, the engagement member 21 and the arm 12 can be easily connected and released.

  In particular, in the present embodiment, the ball lock pin 26 is employed as a rod-like member that connects the engaging member 21 to the arm 12. By adopting the ball lock pin 26, the arm 12 and the engaging member 21 can be easily connected and released. In addition, as a connection means, the arbitrary structures which can change the rotation angle of a 1st coil spring and can connect a 1st coil spring to a brake pedal in a some position are employable. For example, the engaging member may be fixed to the arm using a screw instead of the ball lock pin.

  The first elastic member and the second elastic member that urge the brake pedal are not limited to coil springs, and any member that supplies a reaction force against the depression of the brake pedal can be employed.

  In the respective drawings described above, the same or equivalent parts are denoted by the same reference numerals. In addition, said embodiment is an illustration and does not limit invention. Further, in the embodiment, changes of the embodiment shown in the claims are included.
