Description

  The present invention relates to a pull damper device for damping an operation of a glove box or the like of an automobile.

  Conventionally, there exists a thing of patent document 1 as a pulling damper apparatus.

  This pulling damper device applies a drag force in the direction of pulling the rod, and can, for example, damp the operation of a glove box of an automobile.

  However, since the rod is pulled, each fastening portion is easily detached, and it is necessary to increase the strength of the fastening portion.

  For this reason, it has been difficult to obtain a low-cost pull damper device.

  The objective of making it possible to obtain a low-cost pull damper device was realized by a base adapter and a movable adapter and a shock absorber that generates a drag force by compression.

[Overall configuration of pull damper device]
1 is a side view of the pull damper device, FIG. 2 is a cross-sectional view of the pull damper device, FIG. 3A is a side view of one side of the pull damper device, and FIG. 4 and 4 are perspective views of the base adapter.

  As shown in FIGS. 1 to 3, the pull damper device 1 includes a shock absorber 3, a base adapter 5, and a movable adapter 7. The relationship between the base and the movable is arbitrary and can be changed as appropriate.

  In the shock absorber 3, a rod 11 is coupled to a piston disposed in a cylinder 9, and a recirculation path is formed in the piston. The piston includes a valve capable of opening and closing the recirculation path.

  When both ends of the shock absorber 3 are compressed and the rod 11 enters the cylinder 9 and the piston moves in the same direction, the return path of the piston receives the pressure of the working liquid stored in the cylinder 9 and closes with a valve. And generate drag.

  When the rod 11 extends out of the cylinder 9, the working liquid passes through the reflux path and no drag acts.

  The base adapter 5 and the movable adapter 7 are disposed along the shock absorber 3.

  As shown in FIGS. 1 to 4, the base adapter 5 has a main body portion 13 formed in a rectangular cross-section cylindrical shape, and is fixed to one side of the main body portion 13 by hitting the end portion of the cylinder 9 which is one end of the shock absorber 3. And a base adapter coupling portion 17 on the other side. In the base adapter 5, through holes 19 a and 19 b are formed on both sides of the base adapter contact end 15. The base adapter coupling portion 17 is formed such that a pair 17a and 17b face each other, and coupling holes 21a and 21b are formed.

  The movable adapter 7 is formed in a substantially U-shaped cross section as a whole, and is fitted to the base adapter 5. The movable adapter 7 includes a main body portion 23, and the main body portion 23 includes a pair of opposing plate portions 23a and 23b. The mutual width between the outer surfaces of the pair of plate portions 23 a and 23 b corresponds to the width in the base adapter 5, and the opposing width of the pair of plate portions 23 a and 23 b corresponds to the outer diameter of the cylinder 9.

  A movable adapter abutting end 25 is fixed on one side of the main body portion 23 and fixed to the tip of the rod 11 which is the other end of the shock absorber 3, and a movable adapter coupling portion 27 is provided on the other side. The movable adapter coupling portion 27 protrudes from the pair of plate portions 23a and 23b so that the pair 27a and 27b are opposed to each other, and faces the outside of the base adapter 5 through the through holes 19a and 19b of the base adapter 5, It protrudes from the contact end 15. In the movable adapter coupling portion 27, coupling holes 29a and 29b are formed.

Note that both ends of the shock absorber 3 may not be fixed to the base / adapter contact end 15 and the movable adapter contact end 25. In this case, a return spring of the piston is disposed in the shock absorber 3.
[Dumping]
In the pull damper device 1 of this embodiment, for example, the base adapter 5 is attached to the glove box body side of the automobile, and the movable adapter 7 is attached to the lid side of the glove box.

  The base adapter coupling portion 17 of the base adapter 5 is aligned with the coupling portion on the glove box body side, and the coupling holes 21a and 21b of the base adapter coupling portion 17 and the coupling holes on the coupling portion on the glove box body side A pin is inserted into the pin and a free coupling is performed.

  The movable adapter coupling portion 27 of the movable adapter 7 is aligned with the coupling portion on the lid side of the glove box, and is coupled to the coupling holes 29a and 29b of the movable adapter coupling portion 27 and the coupling hole on the coupling portion side of the lid side. A pin is inserted to allow free rotation.

  The pull damper device 1 is pulled out from the through holes 19a and 19b as shown in FIGS. 5 and 6 with respect to the base adapter 5 when the movable adapter 7 receives a force, for example, by opening the lid of the glove box. . At this time, the rod 11 enters the cylinder 9 and generates a drag as described above.

  Therefore, the lid of the glove box can be opened gently.

  When closing the lid of the glove box, the movable adapter 7 returns into the base adapter 5, and the rod 11 is pulled out of the cylinder 9 with this return, and the piston moves in the same direction without receiving drag.

  Therefore, the lid of the glove box can be closed without difficulty.

[Effect of Example 1]
The first embodiment of the present invention includes a shock absorber 3 that generates a drag force by compression, and a base / adapter contact end 15 that protrudes from an end face of a cylinder 9 that is disposed along the shock absorber 3 and that is one end of the shock absorber 3. The base adapter 5 that contacts the movable adapter 7 that abuts the movable adapter abutting end 25 against the tip of the rod 11 that is the other end, and the base that is provided on the other side of the base adapter 5 and protrudes from the movable adapter abutting end 25. An adapter coupling portion 17 and a movable adapter coupling portion 27 provided on the other side of the movable adapter 7 and projecting from the base adapter contact end 15 are provided.

  For this reason, the pull damper device 1 can be obtained using the shock absorber 3 that generates a drag force by compression by the base adapter 5 and the movable adapter 7.

  As the shock absorber 3, a general-purpose one that generates an effect in the pushing direction can be adopted, and since there are many market results, high reliability can be maintained.

  Since the shock absorber 3 that generates the effect in the pushing direction is used, it is not necessary to increase the strength of the fastening portion of the shock absorber 3 as compared with the conventional pulling damper, and a small and high resistance damper can be obtained.

  The shock absorber 3 that is a damper in the pushing direction is manufactured in a large quantity, so that the price is low and the cost can be reduced.

  A base adapter abutting end 15 may be formed at a position 16 in FIG. 2 to serve as a stopper. In this case, since a stopper function can be provided on the adapter side, it is advantageous in terms of strength over providing a stopper by a single damper.

  FIGS. 7 and 8 relate to the second embodiment, FIG. 7 is a sectional view of the pull damper device, FIG. 8A is a side view of one side of the pull damper device, and FIG. FIG. 9 is a cross-sectional view of the pull damper device showing a pulling state. Note that the basic configuration is the same as that of the first embodiment, and corresponding components are denoted by the same reference numerals, and redundant description is omitted.

  In the pull damper device 1A of the second embodiment, the square cross-sectional areas of the base adapter 5A and the movable adapter 7A are enlarged, and four shock absorbers 3 are arranged.

  When the movable adapter 7A receives a force by opening the lid of the glove box or the like, the movable adapter 7A is pulled out from the through holes 19a and 19b to the base adapter 5A as shown in FIG. At this time, the four rods 11 respectively enter the four cylinders 9 to generate drag.

  Therefore, in this Example 2, a greater effect can be obtained.

  In addition, the four shock absorbers 3 are three-dimensionally stacked and stored compactly, and the increase in size can be suppressed.

  FIG. 10A is a side view of one side of the pull damper device, and FIG. 10B is a side view of the other side of the pull damper device.

  In this example, the base adapter 5B and the movable adapter 7B have a rectangular cross section, and two shock absorbers 3 are arranged.

Even in this pull damper device 1B, the two shock absorbers 3 can provide a greater effect than in the first embodiment.
