Description

Shock absorber

  The present invention relates to a shock absorber for portable electronic devices such as notebook personal computers and PDAs having devices that are susceptible to vibration and shock, and more particularly to a buffer for protecting an information storage device such as a hard disk drive that is vulnerable to vibration and shock from vibration and shock. It relates to the device.

In recent years, the information processing apparatus performance, along with the large-capacity, lighter and smaller, and thinner advances, laptop or PDA such as an information processing apparatus (hereinafter, representative and that the laptop) used in portable applications the It is widely spread.

To These laptops satisfying the high performance and large capacity hard disk drive (hereinafter, referred to as HDD) as an information storage device is incorporated.

  In order to maintain the confidentiality of stored information and to share notebook PCs, these HDDs are frequently removed from and attached to notebook PCs.

  Further, the HDD taken out is carried by itself or managed individually.

  As a result, vibration or impact is applied to the HDD when the laptop is carried or the like due to the product dropping or contact with other objects. As a result, the HDD built in the notebook computer is damaged.

  Further, an HDD carried in a state where it is taken out from a notebook personal computer may be further damaged by direct vibration or impact.

  In order to avoid such a situation, various ideas have been made to prevent damage by suppressing vibrations and shocks applied to the HDD, regardless of whether they are built in a notebook personal computer or taken out from a device and carried.

For example, Patent Document 1 describes an example in which a device that is sensitive to impact such as HDD is protected by an impact absorbing holder, and Patent Document 2 describes an example in which a polyurethane sheet is used as an impact absorbing sheet. Document 3 describes an example in which an HDD or the like is protected by using an elastic shock absorber that absorbs elastic deformation energy and a plastic shock absorber that absorbs plastic deformation energy.

  Although the structure of these shock absorbers is different, the basic structure is to absorb and reduce the impact applied from the outside by compressing and deforming the impact applied from the outside by placing an elastic body functioning as a shock absorber around the HDD. However, this is common in that the HDD is protected.

  FIG. 5 is a diagram showing a schematic structure of a shock absorber for protecting an HDD built in a conventional notebook computer.

In FIG. 5, the buffer member 4 sandwiches the HDD 1 as a buffered body and the buffer member 4 in the space below the main body upper case 2 that is the outer shell of the shock absorber, and the buffer member 5 sandwiches the HDD 1 in the space above the main body lower case 3. The main body upper case 2 and the buffer member 4 are bonded to each other by the double-sided tape 8. The double-sided tape 8 has such an adhesive force that the buffer member 4 and the buffer member 5 do not easily shift laterally.

  FIG. 6 is a diagram showing a buffered state when an impact is applied to the conventional buffer device.

In FIG. 6, for example, when the shock absorber falls in the direction of arrow A, it receives an impact in the direction of arrow B. In this case, the shock-absorbing member 5 sandwiched between the HDD 1 and the main body lower case 3 is compressed and deformed to absorb the impact and relieve the impact applied to the HDD 1.

However, in the above conventional shock absorber, not only the portable information device can be reduced in size and weight, but also a sufficient shock-absorbing effect due to high impact resistance performance cannot be obtained, and both space saving and improvement in impact resistance performance are achieved. It is very difficult.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a shock absorber having a shock absorbing structure having a large impact resistance and a sufficient shock absorbing effect .

In order to solve the above-described conventional problems, a shock absorber according to the present invention includes an outer shell case that houses a buffered body, and the outer shell case and the upper and lower, left, right, and front and rear of the buffered body housed therein. A buffer member is disposed in each space formed between the buffer member and the buffer member and the buffer member, and the outer shell case and the buffer member are fixed. The outer shell case is fixed and stored in three directions perpendicular to the upper, lower, left, and right sides.

According to the shock absorber of the present invention, the buffer members disposed in the space between the outer shell case in the three directions perpendicular to the upper and lower sides, the left and right, and the front and rear of the buffer body are respectively provided to the buffer body and the outer shell case. By storing the buffered body in the outer shell case in a fixed state, when receiving an impact, the cushioning effect of both compression and extension of the cushioning member can be obtained in any impact direction, and there is little space The impact resistance is greatly improved. Therefore, it is possible to effectively realize a reduction in size, weight, and thickness of a notebook personal computer incorporating the shock absorber.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a schematic structural diagram of a shock absorber according to Embodiment 1 of the present invention.

In the present embodiment, FIG. 5, the same arrangement as the conventional example shown in FIG. 6 are denoted by the same reference numerals.

In FIG. 1, a buffer member 4 is disposed in a space between the HDD 1 that is a buffered body and the main body upper case 2 that is an outer shell of the shock absorber, and further, a buffer is provided in the space between the main body lower case 3 on the opposite side and the HDD 1 The member 5 is disposed. Then, the main body upper case 2 and the buffer member 4, the main body lower case 3 and the buffer member 5, the HDD 1 and the buffer member 4, and the HDD 1 and the buffer member 5 are respectively placed on the adhesive 6 at positions facing the HDD 1. And glue. Here, the foaming urethane foam having viscoelasticity and good buffering property and workability is used for the buffer members 4 and 5, and the adhesive 6 is a cyanoacrylate type that can be cured instantaneously to obtain a strong adhesive force. An adhesive is used.

  FIG. 2 is a diagram showing a state in which an impact is applied to the HDD due to the fall of the notebook personal computer and the impact is alleviated by the shock absorber of the present invention.

  In FIG. 2A, for example, when the shock absorber drops in the direction indicated by the arrow A, it receives an impact in the arrow B direction. In this case, the HDD 1 moves in the direction of arrow A. At this time, the buffer member 5 sandwiched between the HDD 1 and the main body lower case 3 is compressed, and the impact applied to the HDD 1 is alleviated. Further, since the buffer member 4 disposed on the opposite side of the buffer member 5 and the HDD 1 is strongly bonded to both the main body upper case 2 and the HDD 1 by the cyanoacrylate adhesive 6, the buffer member 4 extends, The impact applied to the HDD 1 is further alleviated.

In the description of FIG. 2 (a), but considered them to fall susceptible direction most impact effect of HDD 1, the horizontal direction as shown in FIG. 2 (b), as the C direction shown in FIG example In addition, even when falling in a direction perpendicular to the A direction shown in FIG. 2A, the buffer member 4 is placed on the main body upper case 2 and the HDD 1, and the buffer member 5 is placed on the main body lower case 3 and the HDD 1. Ri by the fact that is strongly bonded with cyanoacrylate adhesive 6 respectively, both of cushioning members 4 and 5 are stretched, impact applied to HDD1 is alleviated.

  Further, in the case of the falling direction between the A direction and the C direction, the ratio of compression and expansion of the buffer members 4 and 5 changes, but the impact applied to the HDD 1 is not reduced.

(Embodiment 2)
FIG. 3 is a schematic structural diagram of the shock absorber according to Embodiment 2 of the present invention.

Also in the present embodiment, the same components as those in the conventional example shown in FIGS. 5 and 6 are denoted by the same reference numerals.

3, in addition to the configuration of the first embodiment, disposing the respective buffer member 7 to a buffer space between the side surface 9 of the main body lower case 3 is an outer shell of HDD1 and shock absorber which is an object to be cushion. And bonding a side 9 of the main body lower case 3 and the buffer member 7, HDD 1 a cushioning member 7 at the respective cyanoacrylate adhesive 6. Similarly to the buffer members 4 and 5, foamed urethane foam is used for the buffer member 7.

FIG. 4 is a diagram showing a state in which the shock absorber according to the present invention reduces the impact applied to the HDD due to the fall of the notebook computer.

In FIG. 4A, for example, when the shock absorber drops in the direction indicated by the arrow A, it receives an impact in the arrow B direction. In this case, the HDD 1 moves in the direction of arrow A. At this time, as in the first embodiment, the shock-absorbing member 5 is compressed, and the shock-absorbing shock-absorbing member 4 is further expanded to buffer the shock applied to the HDD 1. 3 is bonded to both the side surfaces 9 of the HDD 3 and the HDD 1 with a cyanoacrylate adhesive 6, so that the shock applied to the HDD 1 is alleviated more than that of the first embodiment by simultaneously expanding the buffer member 7 as shown in the figure. Is done.

As in the first embodiment, as shown in FIG. 4B, the buffer members 4, 5, and 7 are the upper and lower cases 2 , 3 of the main body and the HDD 1 even in the falling direction such as the C direction perpendicular to the A direction. Since the buffer members 4, 5 and 7 are stretched and compressed as shown in the drawing, the impact applied to the HDD 1 is reduced.

In FIGS. 3 and 4 of the above embodiment, the buffer members 4, 5, and 7 are arranged to alleviate the impact in the horizontal and vertical directions with respect to the HDD 1 on the paper surface. Similarly , the HDD 1 that is a buffered body may be fixed to the outer shell case from three directions perpendicular to each other.

  Further, as shown in FIG. 7, a buffer member 10 that wraps the HDD 1 may be disposed. Also in this case, needless to say, a buffer member that wraps the HDD 1 may be arranged in a direction perpendicular to the paper surface.

In addition, the foamed urethane foam, which is a buffer member, the main body case, and the HDD are each bonded with a cyanoacrylate adhesive, and the HDD is fixedly housed in the main body case. Any means can be used as long as it can be fixed to the main body case or the HDD, for example, by inserting a part of the foamed urethane foam into the main body case or the HDD or using a fixing part.

  Further, depending on the required level of impact resistance, it is not always necessary to fix it, and it may be changed to adhesion by an adhesive material such as a double-sided tape.

  Further, the buffer member is not limited to the foamed urethane foam, and the buffer member may be changed according to the buffer specifications such as a silicon buffer material or an acrylic buffer material.

As described above, since the conventional shock absorber uses a shock absorbing effect only in the direction in which the shock absorbing member compresses, the shock absorbing member arranged on the side opposite to the falling direction did not have any shock absorbing effect. In this form, not only compression but also a buffering effect due to expansion can be obtained, so that all the buffer members can be used effectively. Therefore, if the same amount of buffer members as in the conventional case is used, impact resistance performance is improved. If it can be improved and the same buffering effect as before can be obtained, the amount of the buffering member can be reduced, the space of the entire buffering device can be reduced, and portable information such as a laptop computer incorporating the buffering device The effect that the device can be reduced in size, weight, and thickness can be obtained.

  The shock absorber according to the present invention can secure a shock-absorbing stroke necessary for obtaining a sufficient shock-absorbing effect in a space-saving manner, improve shock resistance, and reduce the size and weight of the shock absorber and the laptop computer incorporating the shock absorber. Since it is possible to effectively reduce the thickness, it is useful as a shock absorber that protects an HDD built in a notebook personal computer from an impact.
