Detailed Description

Hereinafter, an embodiment of the passenger safety support device according to the present invention will be described with reference to the drawings. In the present embodiment, an example in which the passenger safety support device of the present invention is provided in a bus will be described.

Fig. 1 is a schematic view showing a state of a passenger H standing in a vehicle cabin in which a passenger safety support device 1 of the present embodiment is installed, fig. 2 is a sectional view taken along line II-II in fig. 1, and fig. 3 is a block diagram showing a schematic configuration of the passenger safety support device 1. In fig. 1 and 2, the right side is the vehicle front.

As shown in fig. 1, the passenger safety assistance device 1 of the present embodiment is a device for assisting a passenger H who stands in a vehicle compartment and holds a strap handle 2 to stand stably when the vehicle is accelerated rapidly, decelerated rapidly, or the like.

As shown in fig. 3, the passenger safety assistance device 1 includes a sensing device 3 that detects the traveling state information of the vehicle, a motor (actuator) 4 that moves the bail handle 2 in the horizontal direction, and a control device 5 that controls the operation of the motor 4 based on the detected or estimated traveling state information of the vehicle.

Here, the sensing device 3 is constituted by an acceleration sensor, and when a sudden change in the traveling state such as rapid acceleration or rapid deceleration occurs in the vehicle, the acceleration sensor can detect the acceleration (the acceleration G in the front-rear direction) caused by the sudden change in the traveling state. For example, when the vehicle is accelerating rapidly, the sensing device 3 can detect the magnitude (absolute value) of the acceleration in the forward direction; when the vehicle is decelerated suddenly, the sensing device 3 can detect the magnitude (absolute value) of the acceleration in the negative direction. The sensing device 3 is mounted on, for example, a body frame of a vehicle not shown.

As shown in fig. 1 and 2, the bail handle 2 includes a bail portion 21 and a grip portion 22 attached to a lower end of the bail portion 21. A long slit 61 having a predetermined size in the vehicle length direction is formed in the ceiling 6 of the vehicle.

The strap portion 21 of the bail handle 2 is suspended below the ceiling 6 through the long slit 61. A slide mechanism (moving mechanism) 7 for freely moving the bail handle 2 in the vehicle length direction is provided in a space S above the ceiling 6 (a space between the ceiling 6 and the top plate 8). The slide mechanism 7 includes a slide unit 71 connected to the upper end of the strap portion 21 of the bail handle 2, and a slide rail 72 supporting the slide unit 71 and enabling the slide unit 71 to slide in the vehicle length direction.

The slide rail 72 is provided to extend in the vehicle length direction in the space S above the ceiling 6. The slide rail 72 is positioned above the long slit 61. Racks are formed on the top and bottom surfaces of the slide rail 72, respectively. Both ends of the slide rail 72 are supported by support members 72a fixed to the top surface of the ceiling 6, respectively.

The slide unit 71 includes a unit case 71a, and a pair of upper and lower pinions 71b and 71c and a motor 4, which are housed in the unit case 71 a. Of the pair of upper and lower pinions 71b and 71c, the pinion 71b is an upper pinion 71b that meshes with the rack on the top surface of the slide rail 72, and the pinion 71c is a lower pinion 71c that meshes with the rack on the bottom surface of the slide rail 72. The upper pinion 71b and the lower pinion 71c have a rotating shaft 71d and a rotating shaft 71e extending in the vehicle width direction, respectively. The rotating shaft 71d and the rotating shaft 71e are rotatably supported in the unit case 71 a. A rotating shaft 71d of the upper pinion 71b as a rotating member is connected to an output shaft of the motor 4. Thus, when the output shaft is rotated by the operation of the motor 4, the upper pinion 71b is also rotated along with the rotation shaft 71 d. Thus, the slide unit 71 can be driven to move in the vehicle length direction along the slide rail 72. Meanwhile, the bail handle 2 connected to the sliding unit 71 is moved along the long slit 61 by the sliding unit 71.

The output shaft of the motor 4 is rotatable in both forward and reverse directions. In fig. 1, if the output shaft of the motor 4 rotates clockwise, the upper pinion 71b and the lower pinion 71c roll on the slide rails 72, and the slide unit 71 moves to the vehicle front side along the slide rails 72. Then, the bail handle 2 connected to the slide unit 71 moves toward the vehicle front side along the long slit 61. In contrast, in fig. 1, if the output shaft of the electric motor 4 rotates counterclockwise, the upper pinion 71b and the lower pinion 71c roll on the slide rails 72 to move the slide unit 71 toward the vehicle rear side along the slide rails 72. Along with this, the bail handle 2 moves toward the rear of the vehicle along the long slit 61.

As shown in fig. 3, the control device 5 is connected to the sensing device 3 through a signal line 51, and is connected to the motor 4 through a signal line 52.

When a sudden change in the traveling state such as rapid acceleration or rapid deceleration occurs in the vehicle, the sensing device 3 detects the acceleration caused by the sudden change in the traveling state, and transmits a detected acceleration signal to the control device 5 through the signal line 51. Upon receiving the acceleration signal, the control device 5 transmits a control signal corresponding to the acceleration signal to the motor 4 through the signal line 52.

Specifically, when the vehicle is rapidly accelerated (the rate of increase in the traveling speed exceeds a predetermined value) and the sensing device 3 detects a positive acceleration, the control device 5 receives the detection signal and outputs a control signal to the motor 4 to rotate the output shaft thereof in the clockwise direction in fig. 1, thereby moving the slide unit 71 together with the bail handle 2 toward the front side of the vehicle. At this time, the rotation speed and the operation amount of the motor 4 (the moving speed and the moving amount corresponding to the movement of the slide unit 71 to the vehicle front side) are proportional to the absolute value of the acceleration in the forward direction detected by the sensing device 3.

On the other hand, when the vehicle is suddenly decelerated (the traveling speed reduction rate exceeds a predetermined value) and the sensing device 3 detects a negative acceleration, the control device 5 receives the detection signal, and outputs a control signal for rotating the output shaft of the motor 4 in the counterclockwise direction in fig. 1 to move the slide unit 71 together with the bail handle 2 to the vehicle rear side. At this time, the rotation speed and the operation amount of the motor 4 (the moving speed and the moving amount corresponding to the movement of the slide unit 71 to the vehicle rear side) are proportional to the absolute value of the negative acceleration detected by the sensing device 3.

Next, the operation of the passenger safety assistance device 1 will be described.

First, the operation of the vehicle at the time of rapid acceleration will be described. Fig. 4 is a schematic diagram for explaining the operation of the passenger safety assistance device 1 at the time of rapid acceleration of the vehicle. As shown in fig. 4, when the vehicle is accelerated suddenly while a passenger H standing in the vehicle compartment holds the bail handle 2 with his or her hand, the vehicle generates a forward acceleration of moving forward. The direction and magnitude of this acceleration can be detected by the sensing means 3. The sensing device 3 transmits information indicating the direction and magnitude of the detected acceleration to the control device 5.

Upon receiving the acceleration information, the control device 5 outputs a control signal for rotating the output shaft of the motor 4 in the clockwise direction in fig. 4. Upon receiving the control signal, the motor 4 operates to rotate its output shaft clockwise in fig. 4. Thereby, the upper pinion 71b and the lower pinion 71c roll on the slide rail 72, and the slide unit 71 moves toward the vehicle front side. Along with this, the bail handle 2 is also moved toward the vehicle front side.

In general, when the vehicle is accelerated rapidly, the occupant H receives a large tilting inertia force to tilt the occupant H toward the rear of the vehicle. In fig. 4, arrow a indicates the traveling direction of the vehicle, and arrow B indicates the direction of the toppling inertia force. The broken line in fig. 4 indicates a posture (posture of tilting toward the vehicle rear) in which the passenger H holding the conventional bail handle receives a large tilting inertia force acting toward the vehicle rear. On the other hand, when the passenger safety assistance device 1 of the present embodiment is used, the loop handle 2 moves toward the vehicle front side (as indicated by arrow C in fig. 4), and therefore the passenger H holding the loop handle 2 receives a pulling force that pulls the loop handle toward the vehicle front side, and the pulling force is opposite to the falling inertia force B, and a part of the falling inertia force B is cancelled, and therefore, the passenger H can be effectively prevented from falling toward the vehicle rear side.

Next, a case when the vehicle decelerates suddenly will be described. Fig. 5 is a schematic diagram for explaining the operation of the passenger safety assistance device 1 at the time of rapid deceleration of the vehicle. As shown in fig. 5, when the vehicle is decelerated suddenly while the passenger H stands in the vehicle compartment and holds the bail handle 2 with hands, the vehicle generates a negative acceleration (deceleration) acting in the forward direction. The direction and magnitude of this acceleration can be detected by the sensing means 3. The sensing means 3 sends information indicating the direction and magnitude of the detected acceleration to the control means 5.

Upon receiving the acceleration information, the control device 5 outputs a control signal for rotating the output shaft of the motor 4 in the counterclockwise direction in fig. 5. Upon receiving the control signal, the motor 4 operates to rotate its output shaft counterclockwise in fig. 5. Thereby, the upper pinion 71b and the lower pinion 71c roll on the slide rail 72 to move the slide unit 71 to the vehicle rear side, and the bail handle 2 is also moved to the vehicle rear side in accordance with this.

In general, when the vehicle decelerates rapidly, the occupant H receives a tilting inertial force that tilts toward the front of the vehicle. In fig. 5, arrow a indicates the traveling direction of the vehicle, and arrow B indicates the direction of the toppling inertia force. The broken line in fig. 5 indicates a posture (posture of tilting toward the front of the vehicle) in which the passenger H holding the conventional bail handle receives a large tilting inertia force acting toward the front of the vehicle. On the other hand, when the passenger safety assistance device 1 of the present embodiment is used, since the loop handle 2 moves toward the vehicle rear side (as indicated by an arrow C in fig. 5), the loop handle 2 applies a pulling force to the passenger H to pull the passenger H toward the vehicle rear side, the pulling force being opposite to the falling inertia force B, and a part of the falling inertia force B is cancelled, so that the passenger H can be effectively prevented from falling toward the vehicle front side.

With the configuration of the present embodiment, since the slide mechanism 7 can move the bail handle 2 in the vehicle length direction, the bail handle 2 can apply a biasing force in the direction opposite to the tilting inertial force generated by sudden change in the traveling state of the vehicle (sudden acceleration or sudden deceleration) to the occupant H, and therefore, part of the tilting inertial force can be cancelled out. As a result, the passenger H can be effectively prevented from falling down.

< modification example one >

Next, a first modification of the present invention will be described. In the above embodiment, the suspension handle 2 is used as the passenger support member of the present invention, and the sliding mechanism 7 is driven by the motor 4 to move the suspension handle 2. In the present modification, the armrest is used as a passenger support member, and the slide mechanism 7 is driven by the motor 4 to move the armrest.

Fig. 6 is a schematic view showing a state in which the passenger H standing in the vehicle compartment grips the armrest 24 with a hand in the present modification. As shown in fig. 6, the armrest 24 is, for example, an armrest provided on a seat 25 in the vehicle compartment. The slide mechanism 7 similar to the above embodiment is disposed inside the seat 25. The armrest 24 is mounted on the top surface of the unit case 71a of the slide mechanism 7. A long slit 25a extending in the vehicle length direction is formed in an upper portion of the seat 25. The upper portion (grip portion) of the armrest 24 protrudes upward from the inside of the long slit 25a and is exposed to the outside. The other structures of the slide mechanism 7 are the same as those of the above-described embodiment.

In the present modification, the passenger safety assistance device 1 is configured such that the slide mechanism 7 is operated to move the armrest 24 in the vehicle length direction when the vehicle traveling state changes abruptly.

Specifically, when the vehicle is accelerated suddenly, the slide mechanism 7 is operated (the motor 4 is operated) to move the armrest 24 toward the vehicle front side (arrow C). As a result, the armrest 24 applies a pulling force to the occupant H that pulls the occupant H forward of the vehicle, and the pulling force cancels a part of the toppling inertia force (arrow B), thereby preventing the occupant H from toppling rearward of the vehicle.

On the contrary, when the vehicle decelerates suddenly, the slide mechanism 7 operates (the motor 4 operates) to move the armrest 24 toward the rear of the vehicle. As a result, the armrest 24 applies a pulling force to the occupant H that pulls the occupant H rearward of the vehicle, and the pulling force cancels a part of the toppling inertia force, thereby preventing the occupant H from toppling forward of the vehicle.

Therefore, the structure according to the present modification can also effectively prevent the passenger H standing in the vehicle compartment from falling down.

< modification example two >

Next, a second modification of the present invention will be described. In this modification, the floor of the vehicle is used as the passenger support member of the present invention, and the moving mechanism is driven by the motor to move the floor.

Fig. 7 is a schematic view showing a state in which a passenger H standing in the vehicle compartment grips the bail handle 2 with a hand in this modification.

In the present modification, the moving mechanism is configured to be able to move the floor 91 of the vehicle in the vehicle length direction. Specifically, as shown in fig. 7, the floor panel of the vehicle includes an upper floor panel 91 and a lower floor panel 92, and a predetermined space is provided between the upper floor panel 91 and the lower floor panel 92. The lower floor 92 is fixed to a vehicle body frame, not shown. As the moving mechanism, racks 91a and 92a extending in the vehicle length direction are provided on the bottom surface of the upper floor 91 and the top surface of the lower floor 92, respectively, and a plurality of pinions 93 are disposed between the racks 91a and 92 a. The rotation shafts 93a of the pinions 93 are connected to output shafts of motors, not shown. By operating the motor and rotating the output shaft of the motor to rotate the pinion gears 93, the lower floor 92 can be moved in the vehicle longitudinal direction with respect to the upper floor 91.

In the present modification, the passenger safety assistance device 1 is configured such that, when the traveling state of the vehicle suddenly changes, the moving mechanism operates to move the upper floor 91 in the vehicle length direction.

Specifically, when the vehicle accelerates suddenly, the motor operates to rotate each pinion 93 counterclockwise in fig. 7, thereby moving the upper floor 91 toward the vehicle rear side (as indicated by arrow C). Since the position of the feet of the passenger H moves toward the rear of the vehicle, the rate of change in speed with respect to the road surface decreases, and the toppling inertia force B acting on the passenger H decreases. This effectively prevents the passenger H from falling backward in the vehicle (as shown by the broken line in fig. 7).

In contrast, when the vehicle is suddenly decelerated, the motor is operated to rotate each pinion 93 clockwise in fig. 7, thereby moving the upper floor 91 toward the vehicle front side (as indicated by arrow a). Since the position of the feet of the passenger H moves toward the vehicle front side, the rate of change in speed with respect to the road surface decreases, and the toppling inertia force acting on the passenger H decreases. This effectively prevents the passenger H from falling forward in the vehicle.

Therefore, the structure according to the present modification can also effectively prevent the passenger H standing in the vehicle compartment from falling down.

The present invention is not limited to the contents described in the above embodiments and modifications, and can be modified as appropriate. For example, in the above-described embodiment and the modifications, an example in which the passenger safety support device 1 of the present invention is applied to a bus is described. However, the present invention is also applicable to subways or other vehicles as long as the vehicle allows the passenger H to take a bus in a standing posture.

In the above-described embodiment and modifications, the occupant support member (the bail handle 2, the armrest 24, and the upper floor 91) is moved in the vehicle longitudinal direction, thereby preventing the occupant H from falling down during rapid acceleration or rapid deceleration of the vehicle. However, the present invention is not limited to this, and the passenger H can be prevented from falling down when the vehicle is suddenly steered by moving the passenger support member in the vehicle width direction.

Specifically, when the bail handle 2 or the armrest 24 is used as the occupant support member, the occupant support member is moved to the right in the vehicle width direction when the vehicle is cornering sharply to the right; when the vehicle makes a sharp turn to the left, the passenger support member is moved to the left in the vehicle width direction. When the upper floor 91 is used as the passenger support member, the passenger support member is moved to the left side in the vehicle width direction when the vehicle suddenly turns to the right side; when the vehicle makes a sharp turn to the left, the passenger support member is moved to the right in the vehicle width direction.

In the above-described embodiment and the modifications, the abrupt change in the traveling state such as rapid acceleration or rapid deceleration of the vehicle is sensed by detecting the acceleration of the vehicle by the sensing device 3. However, the present invention is not limited to this, and the occurrence of sudden acceleration, sudden deceleration, and sudden steering of the vehicle can be estimated by detecting the operation amount of the driving operation performed by the driver (the stepping amount and the stepping speed of the accelerator pedal, the stepping amount and the stepping speed of the brake pedal, and the steering amount and the steering speed of the steering wheel). In addition, the occurrence of rapid acceleration, rapid deceleration, and rapid steering of the vehicle can also be estimated by capturing a video of the traveling direction of the vehicle with an imaging device. For example, when an obstacle exists ahead of the vehicle in the traveling direction, it is estimated that the vehicle will suddenly decelerate.
