Description

  The present invention relates to a shock absorber for reducing a shock when a moving member that is movable in a direction approaching and separating from a stopper member abuts on the stopper member.

  If this type of shock absorber is used in a car audio device, for example, as shown in FIG. 6, a mechanism of a slider 5 is provided inside an electronic device housing 8, and the slider 5 is attached to a longitudinal axis. It is configured to be slidable in the direction, and is provided with a rotating shaft 6 at its tip, and is configured to support a front panel 7 that is rotatable with respect to the rotating shaft 6, and the slider 5 is electrically or manually operated. Accordingly, the front panel 7 moved to a retracted position as shown in FIG. 6 through a mechanism (not shown) that is driven can be moved to a drawing position as shown in FIG.

  One end (lower side) of the front panel 7 is supported by a rotating shaft 6 provided at the tip of the slider 5 and can be opened at an angle of about 90 degrees with the rotating shaft 6 as a fulcrum. The member fixed to is configured as a disc tray for loading and unloading a disc such as a DVD.

  When such a slider 5 is moved from the pulled-out position as shown in FIG. 7 to the retracted position as shown in FIG. 6, rattling in a lock mechanism (not shown) provided to engage with the slider 5 is prevented. Therefore, a buffer member 4 made of an elastic material such as a sponge material is fixed to the outside of the L-shaped upright portion 2 fixed integrally with the tip of the slider 5 via the double-sided adhesive tape 3, A stopper 1 provided integrally with the electronic device casing 8 is fixed on the longitudinal axis of the slider 5.

  With this configuration, when the front panel 7 is in the retracted position with respect to the electronic device casing 8, the upright portion 2 and the stopper 1 are in a state where the buffer member 4 is compressed as shown in FIG. 6. Located between.

  Further, when the slider 5 is in the pulled-out position, as shown in FIG. 7, the upright portion 2 and the stopper 1 are completely separated from each other, so that the buffer member 4 is in a state in which the compression is released.

  Therefore, rattling of the locking mechanism when the slider 5 is pulled into the electronic device casing 8 is absorbed by the buffer member 4.

  As described above, in addition to the device that performs buffering when the slider 5 is locked, for example, an optical disk device disclosed in [Patent Document 1], when a tray that is movable back and forth with respect to the device body is placed in the storage position. In addition, a sponge-like cushioning member is affixed to a gap (opening path of dust) caused by variations in components, variations in assembly, and backlash between components using a double-sided tape.

  The shock absorber for reducing the impact when the moving member that is movable in the direction approaching and separating from the stopper member abuts against the stopper member is used only in the electronic device as described above. Of course, the same or similar configuration is used in the case of being adopted in all of the optical devices and various devices.

Japanese Patent Laying-Open No. 2003-249071 (disclosed in FIGS. 13, 14, [0006] and [0007])

  In the conventional shock absorber, a sponge-like shock absorbing member is fixed to the tip of a moving member such as a slider facing a stopper fixed to the electronic device casing using a double-sided adhesive tape, and the upright portion 2 is fixed to the horizontal base surface 2a. In the case of the upright surface 2b perpendicular to the surface (see FIG. 8), since the surface axis L1 of the stopper 1 and the surface axis L2 of the upright surface 2b are in parallel, the compressive stress of the buffer member 4 is double-sided adhesive tape. 3, the parallel state of the surface axis L <b> 1 of the stopper 1 and the surface axis L <b> 2 of the standing surface 2 b is caused by a dimensional error of parts, a dimensional error during assembly, a gap dimensional error between parts, and the like. If it cannot be maintained (see FIG. 9), for example, if the parallelism of the plate surface of the stopper 1, that is, the perpendicularity between the plate surface of the stopper 1 and the horizontal base surface 2a is shifted, the compressive stress of the buffer member 4 is reduced. Unevenly for each part of double-sided adhesive tape 3 It will be pressurized.

  For this reason, in the example shown in FIG. 9, the compressive stress applied to the lower part of the double-sided adhesive tape 3 is large, the compressive stress applied to the upper part is reduced, and the sliding force component that pulls the double-sided adhesive tape 3 upward. And the contact and separation of the stopper 1 and the upright portion 2 are repeatedly performed, whereby the entire double-sided adhesive tape 3 is moved above the upright surface 2b, and a separation portion 3a separated from the upright surface 2b is generated. There is a fear.

  Further, when the inclination of the standing surface 2b with respect to the horizontal base surface 2a is inclined in a direction opposite to that shown in FIG. 9, the entire double-sided adhesive tape 3 slides downward and the entire cushioning member 4 downwards. There is a risk of moving to.

  In addition, it is considered that the problem that the entire adhesive layer is slid and moved can be solved by adopting a means of applying the adhesive to the surface of the upright surface 2b without using the double-sided adhesive tape 3. However, when this means is adopted, a new problem, that is, a complicated process of applying the adhesive increases, and a process of drying the adhesive also occurs, so this means is a fundamental solution. Can not be.

  The problems in the shock absorber as described above are not only caused when used in electronic equipment, but are also the same when used in all of optical equipment and a wide variety of equipment.

  Accordingly, an object of the present invention is to provide a shock absorber capable of preventing slippage or slippage of the adhesive layer that occurs over time when a double-sided adhesive tape is used without increasing the number of steps. It is in.

  In order to solve the above-described problems, the shock absorber according to the present invention employs the following characteristic configuration.

  (1) A stopper member, a moving member movable in a direction approaching and separating from the stopper member, and a buffer member in which a buffer member is fixed to one end surface of the stopper member and / or the moving member via an adhesive member In the device, a shock absorber that forms an opening in a part of an opposing surface of the stopper member and / or the moving member.

  (2) A stopper member, a moving member movable in a direction approaching and separating from the stopper member, and a buffer member in which a buffer member is fixed to one end surface of the stopper member and / or the moving member via an adhesive member In the device, a shock absorber that forms a recess in a part of an opposing surface of the stopper member and / or the moving member.

  (3) The part according to (1) or (2), wherein a plurality of types of the opening, the depression, and the protrusion are combined in part of the opposing surface of the stopper member and / or the moving member. Shock absorber.

  (4) The shock absorber according to (1) to (3), wherein the moving member is configured to move along a linear axis with respect to the stopper member.

  (5) The shock absorber according to any one of (1) to (3), wherein the moving member is configured to move along an arc axis with respect to the stopper member.

  (6) The buffer device according to any one of (1) to (5), wherein the buffer member is made of foamed resin.

  (7) The buffer device according to any one of (1) to (5), wherein the buffer member is made of an elastic rubber material.

  (8) The buffer device according to any one of (1) to (5), wherein the buffer member is configured by stacking a soft member and a hard member.

  Since the conventional double-sided adhesive tape is used, the work process does not increase.

  Double-sided adhesive tape is used because the double-sided adhesive tape has been devised to prevent the double-sided adhesive tape from shifting or falling off at least one of the stopper member and the movable member that is movable in the direction approaching or separating from the stopper member. In doing so, it is possible to prevent slipping and displacement of the adhesive layer that occur over time.

  [Embodiment 1] using the shock absorber according to the present invention will be described with reference to FIGS.

  The base 9 is a member fixed integrally with a slide member or the like, and moves on a surface axis with respect to the plate surface of the base 9, and a standing portion 10 in which the tip of the base 9 is raised vertically. A circular opening 11 is formed at the center of the upright portion 10.

  A buffer member 13 to which a double-sided adhesive tape 12 having a shape corresponding to the surface shape of the upright portion 10 is attached is attached to the front surface of the upright portion 10, and the surface of the upright portion 10 is attached to the front surface of the upright portion 10 as shown in FIG. The buffer member 13 is fixed using the double-sided adhesive tape 12, and the stopper 1 fixed to the electronic device casing is positioned in front of the buffer member 13. The adhesive tape is not necessarily a double-sided adhesive tape.

  When the base portion 9 is brought into the predetermined drawing position, the stopper 1 and the upright portion 10 are largely separated from each other, and the upright portion 10 of the base portion 9 and the stopper 1 are completely separated from each other. The member 13 is in a free state where compression is not applied.

  Then, when the base 9 is moved in the direction of the arrow a by the action of a slide mechanism (not shown) in order to place it in the retracted position, the buffer member 13 is sandwiched between the stopper 1 and the upright portion 10 as shown in FIG. Compressed in the compressed state.

  Therefore, rattling of the locking mechanism when the base 9 is pulled in by a slide mechanism (not shown) is absorbed by the buffer member 13.

  When such an operation is repeatedly performed, since the substantially central portion of the double-sided adhesive tape 12 is brought into the opening 11, the parallelism of the surfaces of the upright portion 10 and the stopper 1 has a component size deviation. Even if it cannot be secured due to changes over time, even if there is a slip or slip component due to stress non-uniformity that accompanies it, it will be blocked by the part of the double-sided adhesive tape 12 that penetrates into the opening 11, and accordingly The double-sided adhesive tape 12 is prevented from shifting or dropping off over time.

  In [Embodiment 1], one opening 11 is provided in the center of the upright portion 10, but a plurality of openings may be provided. This example is shown in FIGS. 4 and 5 as [Embodiment 2]. I will explain.

  In FIG. 4, a base 9 is a member fixed integrally with a slide member or the like, and moves on the surface axis with respect to the plate surface of the base 9, and the tip of the base 9 is raised vertically. Further, a circular first opening 14 and a second opening 15 are provided on the surface of the rising part 10.

  A buffer member 17 to which a double-sided adhesive tape 16 having a shape corresponding to the surface shape of the upright portion 10 (slightly smaller in this example) is attached is attached to the front surface of the upright portion 10. The stopper 1 fixed to the electronic device casing is positioned oppositely.

  When the base portion 9 is brought into the predetermined drawing position, the stopper 1 and the upright portion 10 are separated from each other, and the upright portion 10 of the base portion 9 and the stopper 1 are completely separated from each other. The member 17 is in a free state where compression is not applied.

  Then, when the base 9 is moved in the direction of the arrow b by the action of a slide mechanism (not shown) to place the base 9 in the retracted position, the buffer member 17 is sandwiched between the stopper 1 and the upright portion 10 as shown in FIG. Compressed in the compressed state.

  Therefore, rattling of the lock mechanism when the base portion 9 is pulled in by a slide mechanism (not shown) is absorbed by the buffer member 17.

  When such an operation is repeatedly performed, a part of the double-sided adhesive tape 16 enters both the first opening 14 and the second opening 15. Even if the parallelism cannot be ensured due to component dimensional deviation or aging, even if there is a slip or slip component due to the stress non-uniformity caused by the dimensional deviation, the first opening 14 and the second opening 15 Accordingly, the double-sided adhesive tape 16 is prevented from being displaced or dropped over time by a plurality of portions, that is, the first opening 14 second and the opening 15 portions.

  In [Embodiment 2], two openings of the first opening 14 and the second opening 15 are provided, but a larger number of openings may be provided, and the arrangement of the plurality of openings is equal. Of course, any of an array, a staggered array, etc. may be used.

  Further, in the buffer structure having the positional relationship between the stopper 1 and the upright portion 10, the double-sided adhesive tape 16 (or the double-sided adhesive tape 12) is attached to the upright portion 10 in both [Example 1] and [Example 2]. Although the buffer members (13, 17) are fixed to each other, the buffer members 13, 17 may be attached to the stopper 1 side without being attached to the upright portion 10. As another structure, the stopper 1 and the upright portion 10 are You may comprise so that a buffer member may be provided in both and the said buffer member may contact | abut / separate.

  Furthermore, the opening 11 provided in either the stopper 1 or the upright part 10 may be a hollow part formed by pressing a plate material.

  On the other hand, instead of the opening on the double-sided adhesive tape forming surface, a protrusion may be formed, or the plate surface itself may be formed in a corrugated shape, or these openings, depressions, and corrugated forming may be employed in combination. Good.

  In any case, the buffer member may be made of a foamed resin, an elastic rubber material, or a soft member and a hard member may be laminated.
