Description

  The present invention relates to a mounting case of an electronic device having a structure that is difficult to transmit vibration and impact generated outside the electronic device unit to an electronic device having a built-in structure, and an electronic device mounting device that detachably mounts the mounting case. In particular, the present invention relates to a mounting housing that hardly transmits external vibration and impact to a detachable hard disk device and a mounting device that detachably mounts the mounting housing.

  2. Description of the Related Art Conventionally, techniques for protecting and using precision electronic devices from vibration and impact have been developed. For example, as a precision electronic device as described above, there is an increasing demand for recording / reproducing devices that have a large recording capacity and can read and write a large amount of data at high speed, for example, hard disk devices while protecting them from vibrations and shocks. ing.

  The hard disk device includes recording / reproducing means for recording / reproducing information at an extremely high density in order to realize a large recording capacity. For example, in a hard disk, a high-density information is recorded by forming a fine recording area on a disk-shaped disk, positioning the recording / reproducing means with respect to the recording area on the disk with high accuracy, and reading and writing information. Is playing. In order to realize a large capacity, information is recorded / reproduced while keeping a very small distance between the recording / reproducing means and the disc. That is, in a large-capacity recording / reproducing apparatus such as a hard disk device, the reproducibility of the position of the recording / reproducing means during operation is extremely important, and high positioning accuracy is required.

  For this reason, it is known that hard disk drives are vulnerable to external vibrations and shocks. If vibration or impact is applied from the outside, the position of the recording / reproducing means is shaken, and accurate recording / reproduction cannot be performed. Further, when the vibration or impact is increased, the recording / reproducing means may come into contact with the disk, and the recording / reproducing means, the disk, etc. may be mechanically damaged and recording / reproducing may not be performed. Therefore, a mechanism has been realized in which recording / reproducing means moves to a position away from the disc when recording / reproducing is not performed today. Also, a mechanism has been realized in which the recording / reproducing means moves to a position away from the disk when the hard disk device senses falling gravity or shock.

  In addition, as a technique for reducing the influence of vibration generated inside the hard disk device, the electrical frequency is connected to the FPC (Flexible Printed Circuit), and a cavity (slit) is provided in the FPC to reduce the natural frequency of a specific frequency. A technique for reducing this is known (Patent Document 1). Patent Document 1 discloses a technique for stabilizing the operation of a hard disk device by controlling the natural frequency at a specific frequency of vibration energy generated mechanically in a hard disk drive by the shape of a slit provided in the FPC.

  On the other hand, the hard disk device is susceptible to vibration during operation, but is also useful for carrying a large recording capacity. For example, a portable computer recording / reproducing device such as a notebook personal computer or a vehicle-mounted road navigation system recording / reproducing device is now widely used as a means for carrying large amounts of electronic information. When the hard disk device is used in an environment where vibration and impact are generated in this way, a damper for absorbing vibration and shock is provided around the hard disk device so that external vibration and shock are not easily transmitted to the hard disk device itself. Technology is known.

  In addition, the hard disk device as described above is also used as a replaceable large-capacity recording medium such as a conventional recording medium such as a compact disk (CD) or a DVD (Digital Versatile Disk). This is realized by a method in which an HDD unit including a hard disk device includes an attachment / detachment mechanism and is attached to / detached from a housing as in the information storage device disclosed in Patent Document 2, for example. In addition, as in the hard disk device disclosed in Patent Document 3, a detachable HDD unit includes vibration damping means, and a technique for carrying a large amount of electronic information in a detachable manner is also known.

By using such a technique, a recording / reproducing apparatus that reads and replaces a large recording capacity, which is difficult to realize with a CD or a DVD, by freely attaching and detaching, and realizing high-speed reading and writing is realized.

  However, in the above-described conventional configuration, the electronic device mounted on the housing is an electronic device that incorporates vibrations and shocks generated outside the housing of the electronic device due to the wiring to which the electronic device is electrically connected. Have the problem of telling.

  FIG. 6 is a cross-sectional view of the HDD unit disclosed in Patent Document 3. As shown in FIG. In the HDD unit 500 shown in FIG. 6, the hard disk device 560 is installed in the HDD unit 500 via vibration damping means 540 provided on the bottom surface of the chassis 510. In addition, the hard disk device 560 is electrically connected to the chassis 510 of the HDD unit 500 by a flexible cable 520 in which a plurality of cables are collected in a flexible band shape or bundle shape.

  The flexible cable 520 connects the hard disk device 560 and the chassis 510 in a slack state. At this time, the HDD unit 500 shown in FIG. 6 is smoothly deformed with respect to vibration and impact that move in the vertical direction (the direction of the z-axis shown in FIG. 6). Therefore, when the HDD unit 500 moves in the vertical direction (the z-axis direction shown in FIG. 6), it is considered that the movement of the HDD unit 500 is not easily transmitted to the hard disk device 560.

  However, the flexible cable 520 grouped in a strip shape is a direction crossing a plurality of signal lines provided in the flexible cable 520 among the directions provided on the surface formed by the flexible cable 520 (the y-axis direction illustrated in FIG. 6). It is particularly difficult to deform.

  That is, when the HDD unit 500 is moved by vibration and impact in a direction crossing a plurality of signal lines provided in the flexible cable 520 provided in the hard disk device 560 (y-axis direction illustrated in FIG. 6), the flexible cable 520 is provided. Is difficult to deform smoothly. In this case, vibrations and shocks generated in the HDD unit 500 may be transmitted to the hard disk device 560 via the flexible cable 520.

  In addition, since the flexible cable 520 is formed by a plurality of flexible cables, the shape and flexibility of the flexible cable 520 change each time the hard disk device 560 is installed in the chassis 510 of the HDD unit 500. Therefore, every time the hard disk device 560 is installed in the chassis 510, the direction of vibration and shock that is easily transmitted to the hard disk device 560 changes, and it is difficult to take measures against vibration and shock of the hard disk device 560.

  Furthermore, since the natural frequency of the flexible cable 520 itself that connects the hard disk device 560 and the chassis 510 changes due to the deformation of the flexible cable 520 as described above, the frequency component of vibration transmitted to the hard disk device 560 can be controlled. was difficult.

  In the HDD unit 500 shown in FIG. 6, the hard disk device 560 is installed in the chassis 510 via vibration damping means 540 provided on the bottom surface of the chassis 510. For this reason, it has been difficult to effectively suppress the movement of the hard disk device 560 against vibrations and shocks in the front / rear, left / right, up / down directions acting on the hard disk device 560.

  FIG. 7 is a plan view of the conventional HDD unit shown in FIG. 6 as viewed from the front. In the HDD unit 500 shown in FIGS. 6 and 7, the hard disk device 560 is installed by vibration damping means 540 provided on the bottom surface of the chassis 510. Therefore, when the HDD unit 500 moves in the vertical direction (the z-axis direction described in FIGS. 6 and 7), the hard disk device 560 is shaken in the vertical direction and the movement is suppressed by the vibration damping effect of the vibration damping means 540. . However, when shaken in the left-right direction or the front-rear direction (the y-axis direction and the x-axis direction shown in FIGS. 6 and 7, respectively), the hard disk device 560 swings while swinging left and right or back and forth around the vibration damping means 540. It will be. FIG. 7 shows the case where vibration is applied in the vertical and horizontal directions. Therefore, in the conventional HDD unit as shown in FIGS. 6 and 7, the direction crossing a plurality of signal lines provided in the flexible cable 520 (the direction of the y-axis as shown in FIGS. Direction) and the direction in which the flexible cable 520 is inserted into the connector of the HDD unit (that is, the x-axis direction shown in FIGS. 6 and 7 and the front-rear direction) are hard to move. Therefore, it is difficult to effectively protect the hard disk device from vibration and impact.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide an electronic device having an anti-vibration structure that is difficult to transmit vibrations and shocks generated outside the housing of the electronic device to the electronic device containing the electronic device. An object of the present invention is to provide a device mounting housing and an electronic device mounting device that detachably mounts the mounting housing.

  According to said structure, the mounted electronic device is installed in the mounting housing | casing by several vibration damping means with which a pair of side surface is equipped. Therefore, even if the electronic device built in due to vibration and impact applied from the outside of the mounting housing is shaken in any direction of front / rear, left / right, up / down, straight line with respect to each direction in which the vibration damping means is shaken. Expansion and contraction can be performed. Therefore, the vibration attenuating means can perform only the action of absorbing and mitigating vibration and shock due to its elasticity, and can effectively suppress the movement of the electronic device due to vibration and shock.

  In addition, the electronic device and the mounting housing are electrically connected by wiring means formed by FPC. Therefore, the shape of the wiring means hardly changes every time the electronic device is installed in the mounting housing.

The action can be suppressed. In addition, since the wiring means is provided with a slit, the wiring means is formed on the mounting housing connector plane and in a direction perpendicular to the connection direction of the wiring means to the insertion port of the mounting housing connector, that is, FPC. The deformation can be smoothly performed in a direction crossing a plurality of signal lines provided in the wiring means. For this reason, the action of the wiring means transmitting the vibration and impact transmitted from the outside of the mounting housing to the electronic device becomes very small. In other words, since the electronic device can be considered to be provided in the mounting housing only by the vibration damping means, it is possible to effectively absorb vibration and impact by the elasticity of the vibration damping means.

  Moreover, it is preferable that a plurality of the slits are provided in the wiring means.

  According to the above configuration, the elastic characteristics of the wiring means due to the plurality of slits, for example, the elasticity and flexibility of the wiring means acting by being in contact with the electronic device, the natural frequency of the wiring means itself, etc. Can be adjusted.

  Moreover, it is preferable that the said slit is the structure formed along the direction in which the said wiring means is provided toward the said mounting housing | casing from the said electronic device.

  According to said structure, the slit is formed in the wiring means formed with FPC along the direction provided toward the mounting housing | casing from an electronic device. Therefore, the elasticity and flexibility characteristics of the wiring means, for example, the vibration transmission action of the wiring means acting when the wiring means mechanically contacts the electronic device, the natural frequency of the wiring means itself, etc. are adjusted. Can do.

  Moreover, it is preferable that two pieces of the vibration damping means are provided on each of a pair of opposite side surfaces of the electronic device.

  In addition, the electronic device and the mounting housing are electrically connected by wiring means formed by FPC. Therefore, the shape of the wiring means hardly changes every time the electronic device is installed in the mounting housing. For this reason, the elastic characteristics of the wiring means, for example, the elastic and flexible characteristics of the wiring means that act when the wiring means is in contact, the natural frequency of the wiring means itself, and the like are not easily changed. Therefore, vibrations and shocks transmitted from the outside of the mounting housing can always be transmitted to the electronic device mounted in the same manner.

  In addition, since the wiring means is integrally formed of FPC, the elasticity and flexibility characteristics of the wiring means, for example, the wiring means by mechanically contacting the electronic device installed in the mounting housing of the wiring means. It is possible to control effects such as vibration transmission action and the natural frequency of the wiring means itself.

And connected. In addition, since the sheet surface of the wiring means is connected in a wavy shape with respect to the direction in which the wiring means is inserted, the wiring means mechanically pushes or pulls the electronic device. The action can be suppressed. In addition, since the wiring means is provided with a slit, the wiring means is formed on the mounting housing connector plane and in a direction perpendicular to the connection direction of the wiring means to the insertion port of the mounting housing connector, that is, FPC. The deformation can be smoothly performed in a direction crossing a plurality of signal lines provided in the wiring means. For this reason, the action of the wiring means transmitting the vibration and impact transmitted from the outside of the mounting housing to the electronic device becomes very small. In other words, since the electronic device can be considered to be provided in the mounting housing only by the vibration damping means, it is possible to effectively absorb vibration and impact by the elasticity of the vibration damping means.

  Further, as described above, the electronic device mounting apparatus of the present invention includes the signal connection unit, and detachably mounts the mounting case of the electronic device described above, and the signal connection means is the signal connection unit.

  The connector connection unit 130 includes a connector 131 (mounting housing connector) for electrically connecting the HDD unit 100 of the present embodiment to the electronic device mounting apparatus 20. The connector 131 of the present embodiment is connected to an FPC harness portion 120 formed by an FPC (Flexible Printed Circuit) formed in a sheet shape. Although details of the FPC harness portion 120 will be described later, in the connector 131 of the present embodiment, the sheet-like FPC of the FPC harness portion 120 is connected to the connector 131 in a planar manner. Further, the connector 131 of the present embodiment is formed as a planar substrate.

  In HDD unit 100 of the present embodiment, connector 161 provided on hard disk device 160 and connector 131 provided on connector part 130 are physically connected by FPC harness part 120 and electrically connected. It is connected. In the HDD unit 100 of the present embodiment, the FPC harness portion 120 is formed by an FPC (Flexible Printed Circuit) formed in a sheet shape.

  In addition, the damper 140 of the present embodiment is a member that physically connects the chassis 110 and the hard disk device 160. In the HDD unit 100 of the present embodiment, the damper 140 is formed on the side surface of the hard disk device 160.

  FIG. 4 is a plan view of the HDD unit 100 according to the present embodiment as viewed from above, and shows a part of the chassis 110 shown in FIG. As shown in FIG. 4, the damper 140 of the present embodiment is a side surface of the hard disk device 160 that is perpendicular to the flat board surface of the connector 131, and a side surface that does not face the connector 131 and the front grill 150. A total of four are provided, two each. That is, a total of four dampers 140 are provided, two on each of a pair of opposite side surfaces of the hard disk device 160.

  These dampers 140 may be provided at any position on the above-described side surface of the hard disk device 160, but may be fixed to, for example, a well-known mounting screw portion (not shown) that the hard disk device 160 includes for fixing. Further, these four dampers 140 may be provided at symmetrical positions on the side surface of the hard disk device 160. Two of the two dampers 140 provided on one side face are opposite to the other side face through the hard disk device 160, that is, in a position symmetrical with respect to the direction in which the FPC harness portion 120 is inserted into the connector 131. Individual dampers 140 may be provided. By installing the hard disk device 160 in the chassis 110 in this way, it can be stably installed.

  The damper 140 can be fixed to the hard disk device 160 by a known method such as screwing.

  The damper 140 according to the present embodiment is a member that absorbs and relaxes vibrations and shocks applied to the chassis 110 from the outside, and is formed of an elastic member. For example, it may be formed of an elastic member such as silicon rubber, or may be formed of an elastic member supported by a fluid such as oil. As such a damper, for example, a damper supplied by Pioneer material Precision Tech as a product expressed as IIR 10 ° as a material and hardness can be used. The damper 140 is not limited to the above-described member, and a well-known one can be used.

  Next, the operation when vibration and impact are applied to the HDD unit 100 of the present embodiment will be described with reference to FIG.

  FIG. 5 is a plan view of the HDD unit 100 according to the present embodiment as viewed from the front, and the front grill 150 is removed for explanation.

  In the HDD unit 100 of the present embodiment, the hard disk device 160 is installed in the chassis 110 by the damper 140 provided as described above. Therefore, when the HDD unit 100 of the present embodiment moves in the vertical direction (the direction of the z axis shown in FIG. 5 and the direction perpendicular to the flat board surface of the connector 131), the hard disk device 160 moves in the vertical direction. The movement is suppressed by the vibration damping effect of the damper 140 while being shaken. Similarly, the left-right direction (the y-axis direction shown in FIG. 5, that is, the direction parallel to the flat board surface of the connector 131 and perpendicular to the direction in which the FPC harness 120 is inserted into the connector 131) and the front-rear direction It can be seen that the movement is suppressed by the vibration damping effect of the damper 140 even when it is shaken in the direction of the x-axis described in FIG. 5 (the direction in which the FPC harness 120 is inserted into the connector 131).

  Since the dampers 140 are provided at a total of four locations, two on the opposite side surfaces of the hard disk device 160 as described above, each of the dampers 140 is linear with respect to the three-dimensional movements in the front, rear, left, right, and up and down directions as described above. Can be stretched. Therefore, the damper 140 only needs to perform an action of absorbing and mitigating vibration and shock due to its elasticity, so that the hard disk device 160 can be effectively protected from vibration and shock.

  In the HDD unit 100 of the present embodiment, the hard disk device 160 and the connector 131 are physically connected by the FPC harness unit 120 and are also electrically connected. The FPC harness portion 120 is integrally formed of FPC as described above. Therefore, when the hard disk device 160 is installed in the HDD unit 100, the shape of the FPC harness portion 120 is less likely to change compared to a conventional configuration using a flat cable. Therefore, vibrations and impacts transmitted from the outside of the HDD unit 100 can always be transmitted to the hard disk device 160 in the same manner.

  In addition, since the FPC harness part 120 is integrally formed with FPC, the elastic and flexible characteristics of the FPC harness part 120, for example, the FPC harness part 120 mechanically contacts the hard disk device 160 provided in the chassis 110. By doing so, it is possible to control the effect of vibration transmission of the FPC harness part 120 and the natural frequency of the FPC harness part 120 itself. Therefore, the vibration transmission effect exerted by the FPC harness portion 120 and the natural frequency of the FPC harness portion 120 itself can be adjusted.

  Further, since the FPC harness portion 120 has a sufficient length and gently connects the connector 161 and the connector 131, it is possible to suppress the action of mechanically pushing or pulling the hard disk device 160. Moreover, since the slit 121 is provided in the FPC harness part 120, it can deform | transform smoothly also with respect to the direction which crosses the several signal wire | line provided in the FPC harness part 120. FIG. Therefore, the action of the FPC harness unit 120 transmitting the vibration and impact applied to the chassis 110 to the hard disk device 160 is extremely reduced. In other words, the hard disk device 160 can be considered to be provided in the chassis 110 only by the damper 140, so that vibration and impact can be effectively absorbed by the elasticity of the damper 140.

  In addition, this invention is not limited to each structure demonstrated above, A various change is possible in the range shown to the claim. Embodiments obtained by appropriately combining the technical means explained in the above invention are also included in the technical scope of the present invention.

  As described above, in the present invention, the hard disk device is fixed to the HDD unit chassis by the damper formed on the side surface of the hard disk device, and the hard disk device is provided outside the HDD unit via the harness formed of FPC. Because it is configured to be electrically connected to various devices, it is difficult to transmit externally applied vibrations and shocks to the HDD unit to the hard disk device, and the dampers effectively absorb and mitigate vibrations and shocks. be able to. Therefore, the present invention provides a known large-capacity recording / reproducing apparatus such as an external recording / reproducing apparatus for a portable computer such as an installation type or a notebook personal computer, a recording / reproducing apparatus for an in-vehicle road navigation system, or a large-capacity recording / reproducing apparatus thereof. It can be used not only for the purpose of detachably carrying the device, but also widely applicable for the purpose of detachably carrying an electronic device that is susceptible to vibration and shock.
