Description

  The present invention relates to a vehicle lifting apparatus.

2. Description of the Related Art Conventionally, as an elevating device mounted on a vehicle, a device that assists an elevating plate in a standing direction using a torsion torque of a torsion bar is known (for example, Patent Document 1).
Japanese Patent Publication No. 63-58731

  In the conventional apparatus disclosed in Patent Document 1, a torsion bar that extends relatively long along the rotation center of the lifting plate is disposed in the lifting plate. Therefore, in order to avoid interference between the lifting plate and the vehicle body floor (for example, the loading platform), the entire lifting plate including the peripheral portion of the rotation center (torsion bar) is not only tilted but also in the standing state. The structure had to protrude beyond the outer edge of the car body floor. Therefore, the conventional device has a problem in that the size (length and width) of the vehicle increases as the lifting plate protrudes outside.

  SUMMARY OF THE INVENTION Accordingly, the present invention provides a vehicle elevating device that stores an elevating plate in an upright state from the outer edge of a vehicle body floor, and that can apply a torque in the erecting direction to the elevating plate by a torsion bar. Objective.

According to the present invention, the vehicle lifting device is arranged in the lifting plate so as to be shifted from the first rotating shaft substantially parallel to the first rotating shaft with respect to the vehicle body of the lifting plate, and one end thereof is lifted and lowered. A torsion bar fixed to the plate, and the other end of the torsion bar supported by the lifting plate so as to be rotatable about a second rotation axis that is substantially parallel to the first rotation axis and deviated from the first rotation axis. A rotating member having a fixed position, and a torsion that is interposed between the rotating member and the slider to cause a relative rotation angle difference between the rotating member and the lifting plate as the lifting plate is tilted. A torque transmission mechanism for twisting the bar and transmitting a reaction force or torque of the twisted torsion bar to the slider so as to give a torque in a standing direction to the lifting plate, and the rotating member includes the second member Two side walls orthogonal to the rotation axis, and one side connecting the two side walls A base having a substantially U-shaped cross-section with the door, has a pressing plate, and is the most important feature that is interposed between one end of the torsion bar the pressing plates and the base.

  According to the present invention, by providing the rotating member and the torque transmission mechanism, the torsion bar can be shifted from the rotation center of the lifting plate, so that the torsion bar is accommodated around the rotation center of the lifting plate. There is no need to secure the part to be. Therefore, when the lift plate is tilted from the stowed storage position to the pull-out position, it can be configured to protrude from the inner side (upper side) of the outer edge of the vehicle body floor to the outer side. It is possible to store in a state where it is erected on the inner side, and to apply a torque in the erection direction to the elevating plate by the torsion bar.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following embodiments and modifications include similar components. Therefore, the same constituent elements are given common reference numerals, and redundant description is omitted. In each figure, FR indicates the front of the vehicle, UP indicates the upper side of the vehicle, and WD indicates the vehicle width direction.

FIG. 4 is a diagram showing a state in which the lifting plate is in a stowed storage position, FIG. 3 is a perspective view of the vehicle lifting device, and is a diagram showing a state in which the lifting plate is in a tilted drawer position, FIG. FIG. 5 is a side view of the vehicle elevating device, showing a state in which the elevating plate is tilted, and FIG. 5 is a perspective view of the vehicle elevating device, in which the elevating plate is tilted. FIG. 6 is a side view of the vehicle elevating device, and shows a state where the elevating plate is tilted and is lowered from the position shown in FIG. 4. FIG. 7 is an exploded perspective view of a part of the vehicle lifting device, and FIG. Is a perspective view showing an enlarged part of a vehicle lifting device.

  A vehicle lifting / lowering device 1 according to the present embodiment is provided at a rear end portion of a truck bed (vehicle body, vehicle body floor) 2, and a pair of substantially extending at the both ends in the vehicle width direction of the cargo bed 2 along the vertical direction. Rails 3 and 3 having a box-like cross section are provided. A slider 4 is supported on each rail 3 so as to be movable up and down. And the raising / lowering board 5 is supported by this slider 4 so that rotation is possible. The pair of left and right sliders 4 are adjusted so as to be positioned at the same height, and the elevating plate 5 is configured to rotate around a first rotation axis Ax1 that is parallel to the loading platform 2 and substantially horizontal. .

  The elevating plate 5 includes a rectangular plate-like main body portion 5a that functions as a platform, and a pair of arms 5b and 5b extending from both ends in the width direction of the main body portion 5a (vehicle width direction in the present embodiment) toward the base end side. These arms 5b, 5b are rotatably supported by the sliders 4, 4, respectively. An end edge 5c on the base end side of the main body 5a is separated from the first rotation axis Ax1. Therefore, in the stowed storage position P0 shown in FIGS. 1 and 2, the elevating plate 5 is disposed on the inner side (the vehicle front side in the present embodiment) from the end edge (outer edge) 2a of the loading platform 2, and FIGS. In the tilted drawing position P1 shown in FIG. 8 and the like, the lifting plate 5 can be arranged so as to protrude outward from the end edge 2a of the loading platform 2 (in the present embodiment, the vehicle rear side).

  A torsion bar 6 that is substantially parallel to the first rotation axis Ax1 is accommodated in the main body 5a of the elevating plate 5. In this embodiment, the torsional torque of the torsion bar 6 is used as the elevating plate by the user. This is used as an auxiliary torque for the 5 rotation operation. That is, by applying torque in the standing direction to the lifting plate 5 by the torsion bar 6, the torque in the tilting direction due to gravity of the lifting plate 5 is reduced, and the operating force of the lifting plate 5 is reduced or tilted when standing. In such a case, the momentum that the lifting plate 5 falls is weakened.

  As described above, in this embodiment, since the end edge 5c of the main body 5a is set at a position away from the first rotation axis Ax1, the torsion axis of the torsion bar 6 is the first rotation axis Ax1. It is off. Therefore, in the present embodiment, the rotating member 7 and the torque transmission mechanism 8 are provided in order to cause the torsion bar 6 to be twisted and to transmit the torsion torque generated by the twist to the slider 4 side.

  A pair of left and right rotating members 7 are provided at the edge of the elevating plate 5 in the width direction, and are rotatable about a second rotation axis Ax2 substantially parallel to the first rotation axis Ax1. . The second rotation axes Ax2 of the two rotation members 7 and 7 are made to coincide. In addition, the second rotation axis Ax2 is preferably substantially coincident with the extension axis of the torsion bar 6, but it is not essential and is slightly shifted in the present embodiment.

  In this embodiment, the torque transmission mechanism 8 is supported by the slider 4 so as to be rotatable about the third rotation axis Ax3 located at a position shifted from the first rotation axis Ax1 and the other end 8b. Is configured as a link arm that is supported by the rotating member 7 so as to be rotatable about a fourth rotating axis Ax4 located at a position separated from the second rotating axis Ax2.

  Specifically, as shown in FIG. 7, the rotating member 7 has a base 7a having a substantially U-shaped cross section and a substantially flat pressing plate 7b, and the base 7a and the pressing plate 7b. Are fastened by screws 7c, and the end portion (other end portion) 6b of the torsion bar 6 is sandwiched. A base bracket 7d fixed to the elevating plate 5 (the arm 5b or the main body 5a) is rotatably attached to the base 7a. The other end (one end) 6a of the torsion bar 6 is fixed to the elevating plate 5 (the main body 5a) (see FIG. 13).

  The torque transmission mechanism 8 serving as a link arm has a substrate portion 8c formed in a substantially rectangular flat plate shape, and projecting piece portions 8d erected substantially vertically from the four corners of the substrate portion 8c. As shown in FIG. 9, when the lifting plate 5 is in the stowed storage position P <b> 0, the rotating member 7 is held and accommodated.

  From the slider 4, a rib 4a having a cross-section projecting sideways is provided, and a shaft 4b corresponding to the third rotation axis Ax3 is attached to the rib 4a.

  The rotating member 7 and the torque transmission mechanism 8 of FIG. 7 are assembled in the state shown in FIG. 8, and as shown in FIG. 8, the notch 2 b formed at the corner of the end edge 2 a of the loading platform 2 and the lifting plate 5. And a notch 5d formed at the corner of the end edge 5c on the base end side of the main body 5a.

  Here, with reference to FIGS. 9-12, the effect | action of these rotation members 7 and the torque transmission mechanism 8 is demonstrated. FIG. 9 is a perspective view of a part of the vehicle lifting apparatus, and shows a state where the lifting plate is in the stowed storage position, and FIG. 10 is a perspective view of a part of the vehicle lifting apparatus, FIG. 11 is a side view of the vehicle elevating device, and shows an enlarged view of the state where the elevating plate is in the stowed storage position, and FIG. It is a side view of the vehicle lifting device, and is an enlarged view showing a state where the lifting plate is in the tilted drawer position.

  9 and 11, the torsion bar 6 is in a free state in which it is hardly twisted in the state where the elevating plate 5 is at the stowed storage position P0. As shown in FIG. 11, in the present embodiment, the third rotation axis Ax3 is arranged to be shifted upward with respect to the first rotation axis Ax1, and the fourth rotation axis Ax4 is the second rotation axis. It can be seen that the first to fourth rotation axes Ax1 to Ax4 are all arranged in a substantially straight line in this state while being displaced upward with respect to the axis Ax2.

  As shown in FIGS. 10 and 12, when the lifting plate 5 is tilted and moved to the pull-out position P1, in the present embodiment, the outer side of the edge 2a (rear of the vehicle) ). Referring to FIG. 12 in comparison with FIG. 11, a link mechanism including a rotating member 7 and a link arm which is a torque transmission mechanism 8 between the elevating plate 5 and the slider 4 which rotatably supports the lifting plate 5. It will be understood that the operation of the rotating member 7 is realized by this link mechanism. In the present embodiment, a parallelogram link mechanism is constructed in which the first to fourth rotation axes Ax1 to Ax4 move while maintaining substantially the apex of the parallelogram.

  Therefore, according to the above configuration from FIGS. 9 to 12, the relative rotation between the rotation member 7 and the lifting plate 5 with the tilting of the lifting plate 5 from the storage position P <b> 0 to the drawing position P <b> 1. It will be understood that an angular difference (approximately 90 deg in the present embodiment) is generated, which causes the torsion bar 6 to be twisted. Considering the elevating plate 5 as a reference now, the torsion bar 6 gives a torque Tc in a direction in which the rotating member 7 is tilted (clockwise in FIG. 12). This torque Tc is also transmitted to the slider 4 as a tensile force f by the torque transmission mechanism 8 configured as a link arm, so that the torsion bar 6 also applies a torque in a tilting direction to the slider 4. become. Here, since the slider 4 is fixed to the loading platform 2 as a vehicle body and does not substantially move, the direction in which the slider 4 rises with respect to the slider 5 by the torsional torque of the torsion bar 6 (reverse to FIG. 12). A torque T in the clockwise direction) is generated. That is, in the present embodiment, the torque transmission mechanism 8 configured as a link arm transmits the tensile force f from the rotating member 7 to the slider 4, thereby giving the rising and falling plate 5 torque T. is there. Further, from the consideration here, the link mechanism in which the slider 4, the lift plate 5, the rotating member 7, and the link arm as the torque transmission mechanism 8 are connected so as to be capable of mutual rotation may not be a parallelogram link mechanism. I can understand that.

  FIG. 13 is a front view of the vehicle elevating device in a state where the elevating plate is stood up (the view seen from the rear of the vehicle). As shown in FIG. 13, the rail 3 has a substantially box-shaped cross section, and a slit 3 a that is elongated vertically is formed in a wall on the rear side of the vehicle. The slider 4 is supported in the rail 3 so as to be movable up and down, and a support portion 4c that supports the elevating plate 5 is exposed to the outside of the rail 3 from the slit 3a.

  As described above, in the present embodiment, in the vehicle lifting device 1, the first lifting shaft 5 is substantially parallel to the first rotation axis Ax1 with respect to the loading platform 2 (vehicle body) of the lifting plate 5. A torsion bar 6 which is arranged offset from the rotation axis Ax1 and has one end 6a fixed to the lifting plate 5, and the lifting plate 5 is substantially parallel to the first rotation axis Ax1 and shifted from the first rotation axis Ax1. A rotating member 7 supported so as to be rotatable about the second rotation axis Ax2 and to which the other end 6b of the torsion bar 6 is fixed, and an elevating plate 5 interposed between the rotating member 7 and the slider 4. When the torsion bar 6 is tilted, a relative rotation angle difference is generated between the rotation member 7 and the lifting plate 5 to twist the torsion bar 6, and the reaction force or torque of the twisted torsion bar 6 is applied to the slider 4. Torque transmission that gives the lifting plate 5 a torque in the standing direction by transmitting to The mechanism 8, and the formed.

  Therefore, by providing the rotation member 7 and the torque transmission mechanism 8, the torsion bar 6 can be shifted from the rotation center (first rotation axis Ax 1) of the elevating plate 5. There is no need to secure a portion for accommodating the torsion bar 6 around the rotation center. Therefore, when the lift plate 5 is tilted from the stowed storage position P0 to the pull-out position P1, the lift plate 5 can be configured to protrude from the inside (upper side) of the end edge 2a of the loading platform 2 to the outside. 5 can be stored in a state of standing up from the end edge 2a of the loading platform 2, and torque in the standing direction can be applied to the lift plate 5 by the torsion bar 6.

  Further, in the present embodiment, the torque transmission mechanism 8 is supported by the slider 4 so as to be rotatable at a position separated from the first rotation axis Ax1 and the other end 8b is secondly supported by the rotation member 7. It was comprised as a link arm supported so that rotation was possible in the position spaced apart from rotation axis Ax2. Therefore, the torque transmission mechanism 8 can be embodied as a relatively simple configuration.

  (Second Embodiment) FIG. 14 is a side view of a vehicle lifting apparatus according to this embodiment.

  In the vehicle lifting apparatus 1A according to the present embodiment, the torque transmission mechanism 8A is configured as a gear mechanism. That is, the torque transmission mechanism 8A includes a gear 8e fixed to the slider 4A, a gear 8f fixed to the rotating member 7A, and a gear 8g that meshes with both the gears 8e and 8f. These gears 8e to 8g are interlocked. The number of teeth of the gears 8e to 8g is the same. The intermediate gear 8g is rotatably supported by the lifting plate 5A. Further, one end 6a of the torsion bar 6A is fixed to the lifting plate 5A, and the other end 6b is fixed to the rotating member 7A.

  In such a configuration, when the lifting plate 5A is tilted, the gear 8g rolls in the clockwise direction of FIG. 14 with respect to the gear 8e fixed to the slider 4A, and the gear 8f of FIG. Rolls counterclockwise. Here, in this embodiment, since the number of teeth of the gears 8e to 8g is the same, when the gear 8g rolls clockwise by one tooth, the gear 8f is opposite to the gear 8g by one tooth. Rolls clockwise (in the opposite direction to the gear 8g). Therefore, also in the present embodiment, as in the case where the parallelogram link mechanism of the first embodiment is configured, the rotating member 7A moves without changing the posture as the lifting plate 5A tilts. become. Therefore, even in the configuration according to the present embodiment, the tilting of the lifting plate 5A causes a relative rotation angle difference (90 deg) between the rotating member 7A and the lifting plate 5A, thereby twisting the torsion bar 6A. .

  When considering the lifting plate 5A as a reference, the torsion torque generated in the torsion bar 6A is also transmitted to the slider 4A due to the meshing of the gears 8e to 8g. Therefore, also in the present embodiment, the torque T in the direction of standing on the lift plate 5A with respect to the slider 4A (counterclockwise direction in FIG. 14) is generated by the torsional torque of the torsion bar 6A.

  Also according to the present embodiment described above, the torque transmission mechanism 8A can be embodied as a relatively simple configuration. Further, in the present embodiment, if the gears 8e to 8g are within the thickness of the lifting plate 5, the torque transmission mechanism 8A advances to the upper surface of the lifting plate 5A while the lifting plate 5A is at the pulling position P1. It is possible to suppress an obstacle when a load or the like is placed on the lifting plate 5A.

  (Third Embodiment) FIG. 15 is a side view of a vehicle lifting apparatus according to this embodiment.

  In the vehicle lifting apparatus 1B according to this embodiment, the torque transmission mechanism 8B is configured as a gear mechanism. However, in the present embodiment, the gear 8e fixed to the rotating member 7B and the gear 8g fixed to the slider 4B are directly meshed, and the number of teeth is the same. Also in this embodiment, one end 6a of the torsion bar 6B is fixed to the lifting plate 5B, and the other end 6b is fixed to the rotating member 7B.

  In such a configuration, the gear 8f rolls 180 (deg) with respect to the tilt of the lifting plate 5B by 90 (deg). That is, also in this embodiment, a relative rotation angle difference (90 deg) is generated between the rotation member 7B and the lifting plate 5B, and the torsion bar 6B is twisted. The plate 5B can be made to act in the standing direction (counterclockwise direction in FIG. 15) as a reaction against tilting.

  According to the present embodiment as described above, the same effect as in the second embodiment can be obtained.

  (Fourth Embodiment) FIG. 16 is a side view of a vehicle lifting apparatus according to this embodiment.

  In the vehicle lifting / lowering apparatus 1C according to the present embodiment, the torque transmission mechanism 8C is configured as a string-like structure (for example, a wire) whose length does not substantially change depending on the tilt of the lifting plate 5C, and one end 8h is a slider. 4C is connected at a position separated from the first rotation axis Ax1, and the other end 8i is connected to the rotation member 7C at a position separated from the second rotation axis Ax2. Arc-shaped guides 8j and 8k are provided on both the slider 4C and the rotating member 7C.

  According to such a configuration, since the rotating member 7C can be pulled with respect to the slider 4C by the torque transmission mechanism 8C configured as a string-like structure, the rotating member can be used even when the lifting plate 5C is tilted. The posture of 7C can be maintained in an upright state. Therefore, as in the first embodiment, the tilting of the lifting plate 5C causes a relative rotational angle difference (90 deg) between the rotating member 7C and the lifting plate 5C, which causes the torsion bar 6C to be screwed. It is done.

  Since the torsional torque can be transmitted from the rotating member 7C to the slider 4C via the torque transmission mechanism 8C as a string-like structure, the torsional torque of the torsion bar 6C also applies to the slider 4C in this embodiment. On the other hand, it is possible to generate a torque T in the direction of standing on the lifting plate 5C (counterclockwise direction in FIG. 16).

  Also according to the present embodiment described above, the torque transmission mechanism 8C can be embodied as a relatively simple configuration. Furthermore, also in this embodiment, if the torque transmission mechanism 8C as the string-like structure and the guides 8j and 8k are set to a size within the thickness of the lifting plate 5C, the torque transmission mechanism is in a state where the lifting plate 5C is at the drawing position P1. It can be suppressed that 8C advances to the upper surface of the lift plate 5C and becomes an obstacle when a load or the like is placed on the lift plate 5C.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made.

  For example, a part of the other end side of the torsion bar can be used as the rotating member. Specifically, for example, the other end of the torsion bar can be bent radially outward as shown in the above embodiments, and the other end can be used as a rotating member. In this case, in order to rotate the other end more reliably, the main body part or arm of the lifting plate is connected to the main body part of the torsion bar (part extending substantially parallel to the first rotation axis, preferably the other end side). It is preferable to provide a rotation support portion that inserts a near portion and supports the torsional rotation. Then, the position of the other end portion on the tip side (position away from the torsion shaft of the other end portion of the torsion bar) and the position away from the first rotation shaft of the slider are a link arm or string shape as a torque transmission mechanism. Connect with a structure. Further, the tip end side of the other end portion may be bent to facilitate connection with the torque transmission mechanism. According to the above configuration, it is possible to obtain substantially the same operation and effect as in the first embodiment or the fourth embodiment, and to reduce the number of parts, thereby contributing to the reduction in manufacturing cost.
