  According to the present invention, a vehicular door closing speed control device, a vehicular door closing speed control method, and a vehicular swing provided with a vehicular door closing speed control device that suppress a force in a closing direction with a simple configuration. A type door can be provided.

  A swing type door of a vehicle provided with a vehicle door closing speed control device according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the swing type door 10 is attached to a side portion of the vehicle body 100 and supported by a hinge 11.

  The swing door 10 includes a door check 20, an absorber 30, and an absorber fixing bracket 40. A wavy line indicates a broken line of the vehicle body 100.

  The door check 20 is a component that limits the opening degree of the swing type door 10. A schematic diagram of the door check 20 is shown in FIG.

  The door check 20 includes a guide arm 21 and a sliding body 22 that is inserted through the guide arm 21 and slides along the longitudinal direction thereof.

  One end of the guide arm 21 in the longitudinal direction is attached to the vehicle body 100. Further, the other end of the guide arm 21 has a stopper 23 for stopping the swing type door 10 from being fully opened.

  The sliding body 22 is fixed inside the swing type door 10, and has a pair of cushion members 24 made of an elastic body such as rubber inside the sliding body 22 and a pair of sliding members 25 arranged therebetween. is doing.

  The sliding member 25 receives pressure from the cushion member when the swing type door 10 is opened and closed, and slides in contact with the guide arm 21.

  The guide arm 21 has a convex part and a concave part, and increases or decreases the pressure with the sliding member 25 inside the sliding body 22 to make the swing-type door 10 open stepwise.

Specifically, when the swing type door 10 is opened and closed, the sliding body 22 slides on the guide arm 21 via the sliding member 25.
And by making the half open position and the full open position of the guide arm 21 into a recessed part, the sliding member 25 becomes easy to rest at this recessed part, and makes the swing type door 10 easy to rest at the half open position and the fully open position.

  The absorber 30 is a device that controls the closing speed of the swing type door 10. A schematic diagram of the absorber 30 is shown in FIG.

  The absorber 30 includes, for example, a cylinder 31, a piston 32, a piston rod 33, an inner tube 34, a return spring 38, and the like. When the swing type door 10 is closed by the absorber fixing bracket 40, a door check is performed. It is fixed at a position where it collides with the other end of the 20 guide arms 21.

  The cylinder 31 is formed in a cylindrical shape, one end is closed, and the other end is provided with an insertion hole for projecting the piston rod 33 to the outside.

  The piston 32 is in the cylinder 31 and is disposed in close contact with the inner tube 34 in the cylinder 31.

  The piston rod 33 has a piston attached to one end, and the other end protrudes from the insertion hole of the cylinder 31. Further, the other end has a piston head 36 with which a control object collides.

  The inner tube 34 is disposed in the cylinder 31 and filled with a liquid 37, and a plurality of orifices (holes) 35 are provided at predetermined intervals in the thickness direction.

  The return spring 38 is a spring for returning the liquid 37 flowing out from the inner tube 34 into the inner tube 34.

  An example of speed control in the case where the absorber 30 having the above configuration is fixed at a place where it does not move and an object to be controlled contacts the absorber 30 will be described below.

When the piston rod 33 is pressed, for example, when a control object comes into contact with the piston head 36, the piston 32 moves in the cylinder 31 in the pressed direction.
At this time, the piston 32 moves while compressing the liquid 37 in the inner tube 34 while being in sliding contact with the inner tube 34.

As a result, the liquid 37 flows out of the inner tube 34 through the orifice 35 in the inner tube 34.
When the pressure on the piston head 36 disappears, the liquid 37 that has flowed out of the inner tube 34 is returned to the inner tube 34 by the return spring 38.

  Thus, the dynamic pressure resistance through which the liquid 37 passes through the orifice 35 decelerates the movement of the piston 32 and the piston rod 33, and also decelerates the movement of the controlled object.

  In the absorber 30 having such a configuration, the strength of the resistance changes depending on the load (speed) of the piston 32. That is, if the piston 32 is low speed, the resistance is small, and if the piston 32 is high speed, the resistance is strong.

  Further, by adjusting the size and number of the orifices 35, it is possible to have a characteristic of decelerating to a constant speed regardless of the magnitude of the load (speed) within a predetermined load (speed). .

  The absorber fixing bracket 40 is a member for fixing the absorber 30 inside the swing type door 10.

  Next, the closing speed control operation of the swing type door 10 including the door check 20 and the absorber 30 as described above will be described with reference to FIG.

  The operation when the door is fully opened, indicated by a dashed line in FIG. 4, through a quarter of the fully opened state indicated by a dashed line, and then the door is fully closed, indicated by a solid line, will be described.

  First, the swing-type door 10 is kept fully open by the door check 20. Here, when the driver or the like starts closing the swing type door 10, the slide body 22 fixed inside the swing type door 10 slides on the guide arm 21 of the door check 20 that is pivotally attached to the vehicle body 100. Move.

  Accordingly, the other end of the guide arm 21 moves through the sliding body 22 through the inside of the swing type door 10.

  When the swing type door 10 starts to close and becomes a quarter of the fully open position shown by the wavy line in FIG. 4, the other end of the guide arm 21 that has moved inside the swing type door 10 collides with the piston head 36 of the absorber 30. To do.

  When the other end of the guide arm 21 and the piston head 36 collide with each other, the absorber 30 starts the speed control described above.

  Since the absorber 30 is fixed to the swing type door 10 by the speed control, the swing type door 10 receives a drag opposite to the door closing direction via the absorber 30.

  The swing-type door 10 is decelerated to a constant speed after the collision due to the characteristics of the absorber 30 described above, and is in a fully closed state indicated by a solid line in FIG.

  As described above, the swing type door 10 is closed in a conventional manner until the swing type door 10 starts to be closed and reaches a quarter of the fully opened state. When the other end of the guide arm 21 of the door check 20 and the piston head 36 of the absorber 30 collide with each other in a state where the quarter of the door check 20 is fully opened, the swing type door 10 starts to decelerate. Decelerate to speed and keep full speed until it reaches full closure.

  As described above, according to this vehicle swing-type door closing speed control device, the speed of the swing-type door 10 is controlled immediately before the door is fully closed, thereby preventing a hand or the like from being caught and the swing-type door 10 being closed. Sound can be suppressed.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible.

  For example, the structure of the absorber 30 of the above embodiment is arbitrary as long as the object of the present invention can be achieved. For example, the inner tube 34 is sealed, an orifice (hole) is provided in the piston 32, and the pressure from the outside is The liquid 37 may flow into the piston to obtain a dynamic pressure resistance.

  Further, the resistance value of the absorber 30 may be adjusted by adjusting the pressure applied in the cylinder 31 by adjusting the volume in the cylinder 31 or the like.
