Description

The present invention relates to a step device provided in a vehicle.

Some vehicles such as automobiles with a high floor position are equipped with a step device in order to improve the ease of getting on and off the occupants. For example, Patent Document 1 discloses a movable side step device provided in a lower part of a side door of a vehicle. In the side step device described in Patent Document 1, a step for getting on and off (side step) is connected to the lower part of the vehicle body via a parallel link, and the side step device gets on and off in the vertical direction (vertical direction and vehicle width direction) with respect to the vehicle body. The structure is such that the steps can be moved. By operating the actuator, the side step device is configured so that the boarding / alighting step can be moved between the storage position stored in the lower part of the vehicle body and the deployment position protruding laterally from the vehicle body.

Japanese Unexamined Patent Publication No. 58-39543

In a vehicle step device as in Patent Document 1, since an occupant is on board the boarding / alighting step, a relatively large load is applied to the boarding / alighting step. Patent Document 1 has a structure in which when an occupant boarded the boarding / alighting step at the deployed position, the actuator regulates the downward movement of the boarding / alighting step.
Here, in order to configure the step device compactly, for example, in a vertical link type step device provided with a link that swings in the vertical direction as in Patent Document 1, the link is rotationally driven by a motor to perform a step for getting on and off. A structure that moves between the storage position and the expansion position can be considered.

However, in the structure in which the link is rotationally driven by an actuator, particularly a motor, as described above, when an occupant or the like gets on the boarding / alighting step at the deployed position, if the boarding / alighting step is to be maintained at the deployed position, the motor is driven. There is a possibility that the shaft will receive an excessive load (torque). Therefore, for example, it is necessary to increase the size of the motor or to suppress the load applied to the motor drive shaft by providing a clutch that regulates the rotation when the motor is not operating. There is a problem that it causes an increase.

The present invention has been made to solve such a problem, and an object of the present invention is to reduce the load on the actuator when a occupant or the like gets on the boarding / alighting step, and to reduce the load on the actuator so that the vehicle can be configured compactly. To provide a step device.

In order to achieve the above object, the vehicle step device of the present invention includes a step for getting on and off, a vehicle body fixing member fixed to the vehicle body, and a step support member in which the step for getting on and off is supported at one end and extends in the vehicle width direction. A first link arm in which one end is rotatably supported by the vehicle body fixing member and the other end is rotatably supported by the other end of the step support member, and one end is the first link. A second link arm rotatably supported by the vehicle body fixing member separated from the arm and outward in the vehicle width direction, and the other end rotatably supported by the other end of the step support member, and the above. It has an actuator that rotationally drives the first link arm, and by rotationally driving the first link arm by the actuator, a deployment position in which the boarding / alighting step is located outside the vehicle body and a lower portion of the vehicle body. A vertical link type vehicle step device that moves in the vehicle width direction to and from a storage position located in, and is provided on at least one of the first link arm and the second link arm, and is provided with the step for getting on and off. At the unfolding position of the above, the first link arm and the second link arm are in contact with each other, and the movement of the first link arm and the second link arm in a direction approaching each other is restricted, and the boarding / alighting step is performed. It is characterized by having a stopper that regulates downward movement.

As a result, at the deployed position of the boarding / alighting step, the stopper regulates the downward movement of the boarding / alighting step. Therefore, even if an occupant or the like gets on the boarding / alighting step at the deployed position, the movement of the boarding / alighting step due to the load can be performed. Be regulated. Since the stopper abuts on the other of the first link arm and the second link arm at the deployed position of the boarding / alighting step, it regulates the movement of the first link arm and the second link arm in a direction approaching each other. The load applied to the first link arm by the load received by the boarding / alighting step at the time of boarding is distributed and received by the second link arm via the stopper. As a result, the load acting on the actuator that rotationally drives the first link arm can be reduced.

Preferably, at the deployment position of the step for getting on and off, the first rotation center, which is the rotation center of the first link arm and the vehicle body fixing member, and the rotation of the second link arm and the step support member. A third rotation, which is the rotation center between the contact position of the stopper and the step support member and the first link arm, with an imaginary line connecting the second rotation center, which is the center of movement, sandwiched between them. The center and should be located on opposite sides of each other.

As a result, the contact position of the stopper and the third rotation center of the step support member and the 1-link arm are located on opposite sides of each other across the virtual line. Even if a downward load acts on the boarding / alighting step, the load (torque) acting on the first link arm from the boarding / alighting step via the step support member and the load (torque) acting on the first link arm via the stopper. The loads (torques) act in opposite directions to cancel each other out, and the torque input to the actuator that rotationally drives the first link arm can be suppressed.

Preferably, the linear distance connecting the second rotation center and the third rotation center and the linear distance connecting the first rotation center and the third rotation center are added. The value is set longer than the length of the virtual line, and at the deployment position of the boarding / alighting step, the third rotation center is located inside the virtual line in the vehicle width direction, and the contact position of the stopper is , It is preferable that the vehicle is located outside the virtual line in the vehicle width direction.

As a result, at the deployment position of the step for getting on and off, the third rotation center of the step support member and the 1-link arm is located inside the vehicle width direction from the virtual line, and the contact position of the stopper is located in the vehicle width direction from the virtual line. The structure is located on the outside and on opposite sides of the virtual line.
Preferably, the actuator is a motor having a drive shaft coaxially or integrally arranged with a support shaft that rotatably supports the vehicle body fixing member and the first link arm.

As a result, at the deployed position of the boarding / alighting step, the stopper regulates the movement of the first link arm and the second link arm in a direction approaching each other, and the load received by the boarding / alighting step when boarding the boarding / alighting step causes the first link arm. The torque received by the motor can be reduced by receiving the load acting on the 1-link arm in a distributed manner by the second link arm via the stopper.

In the vehicle step device of the present invention, the load received by the first link arm is distributed by the second link arm via a stopper when, for example, an occupant is on board the step for getting on and off and a load is applied downward in the deployed position. Therefore, the load received by the actuator can be reduced in order to prevent the boarding / alighting step from moving downward.
As a result, it is not necessary to increase the size of the actuator or to provide a mechanism for restricting the movement of the link mechanism such as the first link arm when the actuator is inactive, and the size of the actuator and the link mechanism is suppressed to a compact structure. Can be a step device.

The members are connected at a portion outside in the vehicle width direction. A step plate 3 is fixed to an end portion of the link arm 14 that is outward in the vehicle width direction. The link bracket 11 and the link arm 14 are arranged at the same front and rear positions of the vehicle. Specifically, the vertical plate member on the front side of the link bracket 11 and the vertical plate member on the front side of the link arm 14, the vertical plate member on the rear side of the link bracket 11 and the vertical plate member on the rear side of the link arm 14 are the same vehicle. It is placed in the front-back position.

The drive link 12 and the driven link 13 are arm-shaped members having a box-shaped cross section, and are arranged such that one end is attached to the link bracket 11 and the other end is attached to the link arm 14 so that the axes extend in the front-rear direction of the vehicle. It is rotatably supported by link pins 21, 22, 23, 24. Therefore, the drive link 12 and the driven link 13 are arranged so as to be swingable in the vehicle width direction with respect to the vehicle body 20.

The drive link 12 is arranged inside the driven link 13 in the vehicle width direction (on the right side of the vehicle). Further, the drive link 12 is formed shorter than the driven link 13.
The first link pin 21 (support shaft, first rotation center) that supports the link bracket 11 and the drive link 12 is integrally formed with the drive shaft of the drive motor 10. The drive motor 10 is fixed to the link bracket 11.

The second link pin 22 that supports the link bracket 11 and the driven link 13 is arranged so as to be separated from the first link pin 21 on the outer side in the vehicle width direction and is offset below the first link pin 21. Is arranged.
On the other hand, in the link arm 14 extending in the vehicle width direction, the third link pin 23 (third rotation center) that supports the link arm 14 and the drive link 12 is arranged at the inner end portion of the link arm 14 in the vehicle width direction. Has been done. The fourth link pin 24 (second center of rotation) that supports the link arm 14 and the driven link 13 is arranged near the inner end of the link arm 14 in the vehicle width direction and is located closer to the inner end of the link arm 14 in the vehicle width direction than the third link pin 23. They are arranged on the outside and downward in the vehicle width direction.

As shown in FIG. 2, in the retracted state where the step plate 3 is located at the retracted position, the drive link 12 and the driven link 13 rotate inward in the vehicle width direction, and the third link pin 23 and the fourth link pin 24 move inward. It is located inside the first link pin 21 and the second link pin 22 in the vehicle width direction.
As shown in FIG. 3, in the deployed state in which the step plate 3 is located at the deployed position, the drive link 12 and the driven link 13 rotate outward in the vehicle width direction, and the third link pin 23 and the fourth link pin 24 move outward. It is located outside the vehicle width direction from the first link pin 21 and the second link pin 22.

As shown in FIG. 4, at the unfolded position of the step plate 3, the upper surface of the step plate 3 is substantially horizontal (parallel to the horizontal plane of the vehicle body 20). On the other hand, in the retracted position of the step plate 3, the step plate 3 is located inside the vehicle width direction from the unfolded position, and the upper surface of the step plate 3 is slightly above the unfolded position and faces outward in the vehicle width direction. It is slightly inclined downward.

By driving the drive motor 10 and rotating the drive link 12, the step plate 3 moves between the retracted position and the deployed position. When the step plate 3 moves from the retracted position to the deployed position, the position of the outermost upper end portion of the step plate 3 in the vehicle width direction moves slightly downward while moving slightly downward as shown by the two-dot chain line Tls in FIG. Move outward in the direction.
FIG. 5 is a detailed configuration diagram of the rear link mechanism 5 in the deployed state. Note that FIG. 5 is an enlarged view of the rear link mechanism 5 in FIG.

As shown in FIG. 5, the drive link 12 is provided with a stopper 30 that regulates the upward rotation of the drive link 12 in the deployed state.
The stopper 30 is made of an elastic body and is arranged between the first link pin 21 and the third link pin 23 toward the driven link 13.
On the other hand, the driven link 13 is provided with a receiving portion 31 between the second link pin 22 and the fourth link pin 24, to which the stopper 30 abuts in the deployed state.

FIG. 6 is a partial schematic view of the rear link mechanism 5 in the deployed state. Specifically, FIG. 6 shows the positional relationship between the first link pin 21, the third link pin 23, the fourth link pin 24, and the contact position 33 between the stopper 30 and the receiving portion 31 at the deployed position of the step plate 3. Shown.
As shown in FIG. 6 and the following equation (1), in the rear link mechanism 5, the linear distance L1 connecting the third link pin 23 and the fourth link pin 24 in the link arm 14 and the length L2 of the drive link 12 ( The length obtained by adding (the straight line distance connecting the first link pin 21 and the third link pin 23) is the length of the virtual line VL which is a straight line connecting the first link pin 21 and the fourth link pin 24 in the deployed state. The length is set longer than Lvl.

Lvl <L1 + L2 ... (1)
Further, in the deployed state, the third link pin 23 is arranged inside the virtual line VL in the vehicle width direction. Further, in the deployed state, the contact position 33 between the stopper 30 and the receiving portion 31 is arranged outside the virtual line VL in the vehicle width direction. That is, in the deployed state, the third link pin 23 and the contact position 33 between the stopper 30 and the receiving portion 31 are located on opposite sides of the virtual line VL.

FIG. 7 is a vertical cross-sectional view showing the structure of the fixed portion between the link arm 14 and the step plate 3.
As shown in FIG. 7, the step plate 3 is formed of a steel material such as aluminum in a hollow box shape. Further, in order to secure the strength of the step plate 3 itself, it has several vertical plates 40 (two in FIG. 7, connecting the upper plate 43 and the lower plate 44).

The inner end portion of the step plate 3 in the vehicle width direction is placed on the upper plate 41 provided at the outer upper end portion in the vehicle width direction of the link arm 14, and is fixed to each other by a plurality of bolts 42. The step plate 3 projects outward in the vehicle width direction from the tip of the link arm 14 on the outside in the vehicle width direction.
The upper plate 43 and the lower plate 44 of the step plate 3 are formed with rib portions 45 having an increased vertical thickness at the tip positions of the link arm 14. The rib portion 45 is formed so that the vertical thickness gradually decreases from the position of the tip end portion of the link arm 14 toward the projecting direction (outside in the vehicle width direction). As a result, the bending of the step plate 3 near the tip of the link arm 14 is suppressed, and the weight of the step plate 3 can be reduced while ensuring the rigidity of the step plate 3.

The upper plate 43 of the step plate 3 is bent at several places to form a non-slip 46. Further, a protector 47 formed of rubber or the like that also serves as a non-slip is supported at the outer tip of the step plate 3 in the vehicle width direction.
Hereinafter, with reference to FIGS. 3, 5 and 6, the load acting on the drive link 12 when the step plate 3 receives a load downward in the deployed state of the step device 1 of the present embodiment will be described.

In the step device 1 having the above configuration, when an occupant is on the step plate 3 and receives a downward load in the deployed state, the link arm 14 has the fourth link pin 24 as the center of rotation and the third link pin. 23 tries to rotate upward and outward in the vehicle width direction (counterclockwise in FIGS. 3 and 5). As a result, the drive link 12 receives a load via the third link pin 23, and the third link pin 23 is upward and outside in the vehicle width direction with the first link pin 21 as the center of rotation (right in FIGS. 3 and 5). Try to rotate around). However, in the deployed state, the stopper 30 comes into contact with the receiving portion 31 of the driven link 13, and the drive link 12 is restricted from rotating outward in the vehicle width direction closer to the driven link 13. As a result, the upper surface of the step plate 3 is maintained in a substantially horizontal state.

In the present embodiment, the total length of the linear distance L1 connecting the third link pin 23 and the fourth link pin 24 in the link arm 14 and the length L2 of the drive link 12 is the first link pin 21. Since the length of the virtual line VL, which is a straight line connecting the fourth link pin 24, is set longer than the length Lvl, the third link pin 23 is inside the virtual line VL in the vehicle width direction at the unfolded position of the step plate 3. To position. Further, since the contact position 33 between the stopper 30 and the receiving portion 31 is located outside the virtual line VL in the vehicle width direction, the contact position of the stopper 30 and the third link pin 23 form the virtual line VL. They are located on opposite sides of each other. As a result, at the unfolded position, when an occupant or the like gets on the step plate 3 and the step plate 3 receives a load downward, the load to be input to the drive link 12 via the third link pin 23 and the corresponding load. The load input from the receiving portion 31 of the driven link 13 to the stopper 30 at the contact position 33 acts on the drive link 12 as torque in opposite directions around the first link pin 21. That is, even if a load acts downward due to the occupant boarding the step plate 3 in the deployed position at the time of getting on and off, the torque around the first link pin 21 acting on the drive link 12 cancels each other out due to this load, and the drive motor The torque (load) acting on the drive shaft when the 10 is not operated can be suppressed.

Therefore, in order to prevent excessive torque from being input to the drive shaft of the drive motor 10, for example, a clutch that regulates rotation when the drive motor 10 is not operating is provided, or the drive motor 10 is enlarged to allow input to the drive shaft. There is no need to increase. Further, since the drive motor 10 that suppresses the output torque enables the step plate 3 to operate and support the step plate 3 at the time of deployment, one of the plurality of link mechanisms 4 and 5 that support the step plate 3 Only one link mechanism can be provided with a small drive motor, and the other link mechanisms can have a simple structure for follow-up operation. As described above, it is possible to reduce the size of the entire step device 1 and reduce the weight and cost.

As a comparative example, when the contact position 33 between the stopper 30 and the receiving portion 31 is changed to the inside in the vehicle width direction from the virtual line VL in the deployed state with respect to the rear link mechanism 5 of the above embodiment, the occupant is placed on the step plate 3. Moves in the direction in which the drive link 12 and the driven link 13 are separated from each other at the contact position 33 when the vehicle is boarded. Therefore, if the structure is such that the stopper 30 faces the driven link 13 side, that is, the outside in the vehicle width direction, and the receiving portion 31 faces the drive link 12, that is, the inside in the vehicle width direction as in the above embodiment, the step. When an occupant gets on the plate 3, the stopper 30 and the receiving portion 31 do not come into contact with each other, and if there is no support by the drive motor 10, the drive link 12 rotates downward and the step plate 3 moves downward. It ends up.

Therefore, when the contact position 33 between the stopper 30 and the receiving portion 31 is set inside the virtual line VL in the vehicle width direction, the stopper 30 provided on the drive link 12 is provided on the driven link 13 so as to face the inside in the vehicle width direction. The receiving portion 31 is arranged so as to face outward in the vehicle width direction so that the stopper 30 and the receiving portion 31 come into contact with each other to regulate the movement of the drive link 12 and the driven link 13 in a direction away from each other. For example, the downward movement of the step plate 3 is restricted in the deployed state. However, with this configuration, when an occupant or the like is on board the step plate 3 and the step plate 3 receives a load downward at the deployed position, the input is input to the drive link 12 via the third link pin 23. Since the load to be applied and the load input from the receiving portion 31 of the driven link 13 to the stopper 30 at the contact position 33 act as torque in the same direction on the drive link 12 around the first link pin 21, the drive motor The torque acting on the drive shaft when the 10 is not operated cannot be suppressed as in the present embodiment.

As described above, in the present embodiment, the contact position 33 of the stopper 30 and the third link pin 23 are located on opposite sides of the virtual line VL so that the occupant or the like can move to the step plate 3 at the unfolded position. When boarding, the stopper 30 restricts the downward movement of the step plate 3, and the torque acting on the drive link 12 can be reduced to reduce the load on the drive motor 10.

The present invention is not limited to the above embodiment.
For example, in the above embodiment, the drive link 12 is rotationally driven by the drive motor 10, but the drive link 12 may be driven by another actuator such as a cylinder instead of the drive motor 10. Even with such a structure, it is possible to reduce the load acting on the actuator when the occupant gets on the step plate 3 at the deployed position.
