Abstract

PROBLEM TO BE SOLVED: To securely protect a protective subject from any vibration and impact by further improving buffer performance to the optional direction of this protective subject, and simultaneously to easily detach the subject. SOLUTION: Four oblate spheroidal buffer structural bodies 10a to 10d are set in the four corners of a magnetic disklike recording medium 12 or a protective subject in making the longitudinal direction accord with a direction being weak against those of vibrations and impulses, and then they are fitted in a gap with a storage case 14. With this constitution, when these vibrations and impulses from the outside are added, a contact surface between these buffer structural bodies 10a to 10d and the storage case 14 shifts from point to face, in the meantime a buffer action works, whereby the magnetic disklike recording medium 12 can be surely protected from vibrations and impulses. In addition, buffer performance is well improvable by means of adjusting the longitudinal direction of the buffer structural bodies 10a to 10d to a direction where the magnetic disklike recording medium 12 should be protected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorbing structure, and more particularly, to a shock absorbing structure disposed between an object to be protected from vibration and impact and a supporting member for supporting the object. For example, the present invention relates to a buffer structure for protecting an electronic device such as a magnetic disk-shaped recording medium or an optical disk-shaped recording medium from external vibration and impact.

[0002]

2. Description of the Related Art In recent years, various types of electronic devices such as precision devices, magnetic disk-shaped recording media, and optical disk-shaped recording media are externally mounted when transported in a state where they are mounted in a device or stored in a storage case. In order to prevent the internal devices from malfunctioning or being damaged by vibrations and shocks applied from the outside, they have been mounted or housed with an elastic member for vibration isolation and cushioning interposed therebetween.

FIGS. 11 and 12 show examples of shapes and arrangements of vibration-damping and shock-absorbing elastic members arranged in a conventional electronic device, and FIG. 13 shows a case where the conventional electronic device is housed. The shape of the vibration-damping / buffering elastic member arranged in the storage case and an example of its arrangement are shown.

In FIGS. 11 to 13, a conventional elastic member is an electronic device 5 such as a magnetic disk-shaped recording medium (FD).
0, elastic members 52a to 52d, and elastic members 54a to 54d arranged at four corners for protecting the electronic device 50 from vibration and impact.
54d, a storage case 56 for storing the electronic devices, and elastic members 58a to 58d for protecting the electronic devices arranged at the four corners of the inner wall of the storage case 56 from vibration and impact.

[0005] As shown in FIGS. 11 to 13, a conventional electronic device 50 and a cushioning structure constituted by elastic members 52, 54, 58 disposed on the side of a storage case 56 for storing the same are: Most of them are provided at or near the four corners of the electronic device 50, and the shape is a rectangular parallelepiped, a cube, a cylinder, or a combination thereof. The case) and the elastic member interposed therebetween were all in surface contact, and were firmly connected and fixed by bonding or connecting parts.

[0006]

However, in such a conventional buffer structure, since the electronic device, the storage case supporting the electronic device, and the elastic member are in contact with each other, the buffer performance is low. Vibration and impact are apt to be easily transmitted, and there is a disadvantage that an extremely large impact from the outside may cause a failure of the internal electronic device.

Therefore, for example, Japanese Utility Model Laid-Open No. 62-10639
In the vibration isolating structure disclosed in Japanese Patent Application Publication No. 1 (1993), the cushioning performance is improved by using a substantially spherical elastic member. This substantially spherical elastic member is in contact with a point or a line in a normal state by being interposed between an acoustic device to be protected and a device housing, and has a point contact or a point contact when externally applied vibration or impact. An attempt was made to obtain a buffering effect during the transition from line contact to surface contact. However, since the object to be protected in the above publication is a vehicle-mounted acoustic device, and it is necessary to deal with various vibrations and impacts applied from all directions, it is considered that a substantially spherical elastic member is used. .

However, since the shape of a substantially spherical elastic member is almost spherical even if the size and material of the elastic member are changed,
Although it can have a uniform damping effect against vibrations and shocks from all directions, there is a limit in trying to improve the damping performance in a predetermined direction. there were. In particular, recent electronic devices are very sensitive to vibrations and shocks, and thus it is essential to improve the buffer performance.

Further, some objects to be protected are vulnerable to vibration or impact from a specific direction. Therefore, in the buffer structure as in the above-mentioned conventional example, it is difficult to protect from such vibration or impact. There was an inconvenience that it was very difficult.

Further, in the conventional shock absorbing structure, an elastic member serving as a vibration damping material or a shock absorbing material is adhered to an object to be protected such as an electronic device or a case for accommodating them, or is fixed by connecting parts or the like. Therefore, there is an inconvenience that it takes a certain amount of labor and time to attach and detach the electronic device and the like.

The present invention has been made in view of the inconveniences of the prior art, and further protects the object to be protected from vibrations and shocks by further improving the cushioning performance of the object to be protected in any direction. A first object is to obtain a buffer structure that can be used.

It is a second object of the present invention to provide a cushioning structure in which an elastic member is fitted into a gap between an object to be protected and a support member so that the object to be protected and the like can be easily attached and detached.

[0013]

In order to achieve the above-mentioned object, in a cushioning structure according to the present invention, an object to be protected from vibration or impact and a support for supporting the object to be protected are provided. The cushioning structure that is placed between the members has a spherical shape with a long axis direction and a short axis direction, and is composed of a resilient elastic member that deforms itself and relieves vibration and shock. The long axis direction of the elastic member is aligned with the direction in which the object to be protected is protected from vibration and impact.

According to this, the elastic member is composed of an oblong elastic member having a major axis direction and a minor axis direction, and the major axis direction of the elastic member is aligned with the direction to be protected from vibration and impact of the object to be protected. By arranging in such a manner, the buffer performance in the direction can be further improved, and the object to be protected can be surely protected.

In the buffer structure according to the next invention,
The object to be protected is an electronic device and is formed of an elastic member having an insulating property.

According to this, the electronic device can be protected from external vibrations and shocks, and since the elastic member has insulating properties, the object to be protected is protected from external electric influences. be able to.

In the buffer structure according to the next invention,
The support member is a storage case for storing the object to be protected, and a hole is formed in the storage case in a direction orthogonal to a mounting / removing direction of the object to be protected, and the pin structure support slides in the hole. Thereby, the elastic member is detachably fixed to the storage case.

According to this, since the elastic member can be detachably fixed to the storage case by the pin structure support that slides in the hole formed in the storage case, the object to be protected can be easily attached and detached. It can be carried out.

In the buffer structure according to the next invention,
The length of the oblong elastic member in the major axis direction and the minor axis direction is changed in accordance with the direction of protection and the degree of protection from vibration and impact of the object to be protected.

According to this, the lengths of the oblong elastic member in the major axis direction and the minor axis direction are changed according to the direction in which the object to be protected is protected from vibration and impact and the degree of protection. Thus, a buffer structure having a buffer performance suitable for the object to be protected can be provided.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a buffer structure according to the present invention.

(Embodiment 1) FIG. 1 shows Embodiment 1
1 is a perspective view showing a state in which the buffer structures 10a to 10d according to the present invention are mounted on the protection target 12, and FIG. 2 shows the protection target 12 with the buffer structures 10a to 10d in FIG.
FIG. 3 is a perspective view showing a state in which the object to be protected 12 is stored in the storage case 14 of FIG. The figure is shown.

The buffer structure 10a according to the first embodiment
Here, to protect the magnetic disk-shaped recording medium (hereinafter also referred to as the magnetic disk-shaped recording medium 12) as the protection target 12 from external vibrations and shocks, an elastic member having a predetermined shape is placed at a predetermined position. It is arranged.

In FIG. 1, the buffer structures 10a to 10d are magnetic disk-shaped recording media 12 as electronic equipment.
Are arranged at the four corners, respectively. Here, the spheroidal elastic member has a three-dimensional shape called a spheroid, and the spheroid is a three-dimensional shape formed by one rotation around a long axis or a short axis of a so-called ellipse. is there. As described above, by forming the elastic member into a spheroid (hereinafter, collectively referred to as an oblate spheroid) and using it,
In particular, it is possible to obtain the buffer structures 10a to 10d with improved buffering performance (vibration-proofing, buffering action) in the long axis direction.

As shown in FIG. 3, for example, as shown in FIG. 3, the smaller the contact area between the storage case 14 and the lid 16 becomes (the longer axis) The contact area in the direction is smaller than the contact area in the short axis direction), and the action of dispersing vibration and impact from one direction to the other direction, that is, the action of converting the vibration energy into the oscillation energy in the other direction. Since the strength is remarkably enhanced, the buffer performance can be dramatically improved.

The damping capacity of the buffer structures 10a to 10d can be significantly increased as the contact area with the storage case 14 and the lid 16 decreases, so that the vibration response magnification is dramatically reduced. It is possible to do.

As described above, the buffer structures 10a to 10a to reduce the contact area with the storage case 14 and the lid 16 are reduced.
Considering the shape of 0d, the ratio of the surface area to the volume is small, the contact surface with the storage case 14 or the lid 16 is close to a point, and the contact area can be minimized. This corresponds to the major axis direction of the above-mentioned oblate (spheroidal) buffer structure, and the buffer structure 10a is adapted to the direction weak in vibration and impact in the magnetic disk-shaped recording medium 12 such as an electronic device. By attaching the long axis directions of 10 to 10d together, the buffering action in that direction can be further enhanced.

FIGS. 4 to 6 show diagrams in which the effects of the vibration-proofing and the buffering action according to the shape of the elastic member described above have been confirmed by experiments. FIG. 4 shows a comparative example showing the relationship between the frequency ratio and the response magnification when the shape of the elastic member is a rectangular parallelepiped or similar, and FIG. 5 shows the frequency ratio and the case where the shape of the elastic member is spherical. A comparative example showing the relationship with the response magnification is shown, and FIG.
Shows an example of Embodiment 1 showing the relationship between the frequency ratio and the response magnification when the shape of the elastic member is oblate.

4 to 6, the contact area of the buffer structure contacting the storage case and the lid becomes smaller. For example, when comparing the response magnification at a frequency ratio (1.0), FIG. 4 has a response magnification of about (6.5), and the sphere of FIG. 5 has a response magnification of about (2.1). It can be seen that the number has decreased.

Further, in FIG. 6, the response magnification is about (1.6) in the case of an oblate spheroid capable of enhancing the buffering action in a direction particularly vulnerable to vibration and impact of the electronic device, and the rectangular parallelepiped shape of FIG. 4 is obtained. Compared with the response magnification of about (6.5), it can be seen that the response magnification is drastically reduced to about 1/4.

Although not shown here, the damping capacity also increases in the order of FIG. 4 → FIG. 5 → FIG. 6 according to the same tendency as the above-mentioned response magnification, and the shape of the elastic member is compared with that of a rectangular parallelepiped or a sphere. Compared to the examples (FIGS. 4 and 5), the spheroid (FIG. 6) of the first embodiment has the best damping ability.

In the first embodiment, the buffer structure 10c (other 10a, 10b, 1
0d has the same shape), as shown in FIG. 7, the major axis direction diameter of the buffer structure 10c is (a), as shown in FIG.
The diameter in the minor axis direction is (b), and the magnetic disk-shaped recording medium 1
2 is (c), the thickness in the major axis direction of the buffer structure 10c is (d), and the thickness in the minor axis direction of the buffer structure 10c is (e). By changing the dimensions of each part up to (e) in accordance with the magnitude of vibration or shock applied to the magnetic disk-shaped recording medium 12, the emphasis is placed on a predetermined direction necessary for protection of the magnetic disk-shaped recording medium 12. Buffer performance can be obtained.

FIG. 8 is a diagram showing the relationship between the contact area ratio and the response magnification ratio between the buffer structure having three shapes (a and b) and the storage case or lid. Have been. In FIG. 8, the case where the buffer structure 10 has a spherical shape (a = b) in which the major axis direction diameter (a) and the minor axis direction diameter (b) are equal is shown by a solid line, and is oblate spherical (a> b). Is shown by a rough broken line, and the case of an oblate spheroid (a <b) is shown by a fine broken line.

As shown in FIG. 8, in each case, the response magnification ratio decreases as the contact area ratio decreases, and the buffer structure 10 has a spherical shape (a> b: rough broken line) and a spherical shape (a = B: solid line), the response ratio of the oblate sphere (a> b) to the contact area ratio is always lower than that of the sphere (a = b), and the better buffer It can be seen that the performance has been obtained.

Also, in electronic devices such as the magnetic disk-shaped recording medium 12, an oblate spheroid in which the thickness of the buffer structure 10 in a direction particularly vulnerable to vibration and impact is increased (a> b: rough broken line)
When comparing the difference in cushioning performance between the case of (b) and the case of a spherical ball (a <b: a fine broken line) in which the thickness of the buffer structure 10 is reduced, the spherical ball (a <b) In the case of a> b), the ratio of the response magnification to the contact area ratio is lower, and it can be seen that good buffer performance is obtained.

FIG. 9 shows the relationship between the degree of impact (G) received by the electronic device and the passage of time (T) when a certain impact is applied to the electronic device protected by the buffer structures of various shapes. A diagram is shown, in which a comparative example using a buffer structure having a rectangular parallelepiped or a similar shape is diagram A,
A comparative example using a spherical buffer structure is a diagram B, and a first embodiment using an oblate (here, a> b) buffer structure is a diagram C.

As can be seen from the measurement results shown in FIG. 9, when the spheroidal buffer structure according to the first embodiment is used, a large damping capacity can be obtained. It can be seen that an excellent buffer effect can be obtained.

In the first embodiment, sorbosane (SORBOTHANE: registered trademark) manufactured by Sanshin Kosan Co., Ltd., which is commercially available, is used as the material of the buffer structure. This material is suitable for use environment for electronic equipment because it has strong insulation properties against aging and heat, and it is easy to manufacture and mold, so it is possible to save processing costs during manufacturing. . When this sorbosein is installed as a buffer structure in an electronic device or a storage case, the material itself has adhesiveness, so it is only necessary to fit three or more places between the electronic device and the case. Becomes

Further, as shown in FIG. 3, when the storage case 14 and the lid 16 cover the buffer structure, the adhesion of the material causes the adhesion of the material irrespective of the installation position of the electronic device. It is no longer necessary to take measures to prevent falling off, so that the assembling work time can be significantly reduced as compared with the conventional case. Also, when removing electronic devices,
Since the buffer structure is not adhered to the electronic device or the case or is not firmly connected and fixed with connecting parts, it is very simple and hassle-free.

Next, the operation of the first embodiment will be described. First, as shown in FIG. 1, a magnetic disk-shaped recording medium 12 as an object to be protected is provided with spheroidal buffer structures 10a to 10d for vibration isolation and buffering at four corners. As shown in FIG. 3, the inside of each of the spheroidal buffer structures 10a to 10d is a magnetic disk-shaped recording medium 1 as shown in FIG.
2, it can be easily attached to the magnetic disk-shaped recording medium 12 as it is.

Then, as shown in FIG. 2, the magnetic disk-shaped recording medium 12 to which the buffer structures 10a to 10d are attached is put into a storage case 14 as it is, and as shown in FIG. And covered with the lid 16.

As described above, the shape of the buffer structures 10a to 10d attached to the magnetic disk-shaped recording medium 12 according to the first embodiment is in a direction in which the magnetic disk-shaped recording medium 12 is susceptible to vibration and impact (here, , The vertical direction in FIG. 3).

That is, as shown in FIG.
Buffer structure 10 for supporting magnetic disk-shaped recording medium 12
c, when the magnetic disk-shaped recording medium 12 is particularly vulnerable to vibration or impact from the vertical direction on the paper surface, the buffer structure 1
By setting the size of the oblate sphere of 0c to (d> e), it is possible to obtain a buffer structure having more excellent vibration proofing and buffering action in the vertical direction.

Further, since the buffer structure 10c is oblate, even if the magnetic disk-shaped recording medium 12 is not so susceptible to vibration or impact (such as the horizontal direction in FIG. 7), the buffer structure 10c has a certain degree of buffer performance. Therefore, the magnetic disk-shaped recording medium 12 can be reliably protected from any vibration or impact.

As described above, according to the first embodiment, the magnetic disk-shaped recording medium 12, which is an object whose shape of the buffer structures 10a to 10d is to be protected, is elongated in a direction particularly susceptible to vibration and impact. By making the shape of the spheroid match the axial direction, the contact area with the storage case 14 and the lid 16 is greatly reduced, the response magnification is remarkably reduced, and the damping capacity can be remarkably increased. The performance and the buffer performance can be dramatically improved.

In particular, since the direction of the buffering performance to be enhanced can be changed in accordance with the object to be protected, the electronic equipment and the like can be more effectively and reliably protected from vibration and impact. In this regard, compared to the conventional spherical buffer structure, it has direction selectivity against vibration and impact,
It can be used properly depending on the purpose and the target, and the buffer performance can be improved.

Further, in the first embodiment, since sorbosane, which is a sticky and flexible elastic member, is used as the material of the buffer structure, it can be used by being fitted between the electronic device and the case. This makes it easy to replace and replace electronic devices, or to process and assemble during manufacturing, thereby reducing manufacturing time and manufacturing costs.

As shown in FIG. 3, when the buffer structure 10 is covered with the storage case 14 or the lid 16, the electronic device can be stored in the case via the buffer structure regardless of the posture in which the electronic device is stored. The electronic device can be protected from vibrations and shocks simply by being fitted into the electronic device. Further, since sorbosein, which is an elastic member, has insulating properties, it is possible to protect electronic components from external electrical influences.

In the first embodiment, a magnetic disk-shaped recording medium has been described as an electronic device to be protected. However, the present invention is not limited to this, and a more accurate electronic component such as a hard disk device may be used. It can also be widely applied for vibration isolation and shock absorption of small precision equipment having a precise driving mechanism.

As described above, according to the second embodiment, even when the storage case 14 has no lid and is not in a state of covering the buffer structure, the pin structure supports 22a to 22d can be used. The bodies 20a to 20d can be fixedly installed on the storage case 14 side, and it is possible to prevent the buffer structure and the disk-shaped recording medium from falling out of the storage case 14.
