Description

  The present invention relates to a component fixing structure, and more particularly to a component fixing structure for fixing a component incorporated in an electronic apparatus such as an information processing apparatus to a support member.

  In an information processing apparatus such as a personal computer, the optical drive apparatus or the like is often unitized in order to facilitate incorporation into an information processing apparatus such as an optical drive apparatus. When incorporating such a unit into an information processing apparatus, for example, it is common to attach the unit to a bracket and incorporate the unit into the information processing apparatus together with the bracket. That is, the unit is incorporated into the information processing apparatus via the bracket.

  The bracket is generally formed of a thin metal plate, and has a screw hole for attaching the unit. When attaching the unit to the bracket, the unit is attached to the bracket by screwing the screw into the screw hole and tightening.

  Here, for example, when the unit is an optional component and the unit is not attached, a unit dummy is incorporated in the bracket instead of the unit. The dummy is generally a part formed of a metal plate that imitates the shape of the unit, and plays a role of covering the space where the unit disappears. Therefore, the dummy is much lighter than an actual unit and does not need to be firmly fixed to the bracket using screws.

  Therefore, in order to fix the dummy to the bracket, a structure is often used in which a pin is provided at a portion aligned with the screw hole, and the dummy is attached to the bracket simply by inserting the pin into the screw hole. In this case, a screw tightening operation for fixing the dummy to the bracket is unnecessary, and the assembly process can be simplified.

  However, in the mounting structure in which the dummy pin is simply inserted into the screw hole, there may be a problem that the dummy rattles due to vibration during operation of the apparatus and abnormal noise is generated. That is, in order to insert the pin into the screw hole, the pin diameter must be smaller than the screw hole diameter, and the pin diameter is set smaller than the screw hole in consideration of variations in the pin position. Play occurs between the holes, and the pins move in the screw holes and hit the inner surface of the screw holes to generate noise.

  In addition, for example, the assembly process may be simplified by setting the unit to be the same as the dummy attachment. In such a case, there is a concern that the unit may vibrate and adversely affect the performance of the unit.

  As an attachment method for preventing such rattling of component attachment, there is a method of attaching a component to a support member with an adhesive material. This method is, for example, a method in which a part is attached to a support member with a double-sided adhesive tape or the like. However, if the adhesive force is lost due to aging of the adhesive material, a problem of rattling occurs.

  Alternatively, there is a method of absorbing vibration by providing an anti-vibration damper between the component and the support member. However, the vibration proof damper is more expensive than the double-sided adhesive tape described above, and there is a problem that a space for providing the vibration proof damper must be secured. Further, when the vibration isolating damper is used when attaching the actually operating unit as described above, the unit performance may be deteriorated due to the frequency characteristics of the vibration isolating damper.

Here, as a component fixing structure for attaching the plate member to another support member without using a screw, a method of sandwiching and fixing the plate member using a grommet has been proposed (see, for example, Patent Document 1). .) According to this attachment method, since the elastic grommet is inserted and fitted into the through hole of the plate member and the support member, the plate member can be attached to the support member without rattling.
JP 2006-83936 A

  According to the above-described component fixing method using a grommet, the grommet must be prepared as a component separate from the plate-like member to be attached, which increases the number of components and leads to an increase in cost. Further, a jig for deforming the grommet at the time of attachment is required. Furthermore, a process for deforming and attaching the tool grommet using the jig is required, and the number of assembling steps is also increased.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a component fixing structure that can attach a component to a support member with a simple structure without rattling, and an electronic device that employs the structure. .

  According to the present invention, there is provided a component fixing structure for attaching and fixing a component to a support member, the component and at least one projecting member provided so as to project from one of the support members, and the component. A sheet-like member that is provided on the other of the support members and that is attached to the other of the component and the support member so as to cover a hole that receives the protruding member and a region in which the hole is provided. When the protruding member is inserted into the hole, the sheet-like member is pressed and deformed by the protruding member, so that a part of the sheet-like member enters the hole. A component fixing structure is provided.

  According to the above-described invention, when the protruding member attached to the support member or the component is inserted into the hole of the component, the sheet-shaped member is pressed and deformed by the protruding member, whereby a part of the sheet-shaped member is formed. The sheet enters the hole, and a part of the sheet-like member is sandwiched between the protruding member and the inner surface of the hole. Thereby, the protruding member is fixed so as not to move in the hole, and the fixing without rattling is achieved. According to the present invention, it is possible to achieve fixing without rattling with a simple structure in which the sheet-like member is simply pasted so as to cover the hole of the support member or component.

  An embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view of a personal computer using a component fixing structure according to an embodiment of the present invention. FIG. 2 is a side view of the personal computer shown in FIG. FIG. 3 is a rear perspective view of the personal computer shown in FIG. 4 is an exploded rear perspective view of the personal computer shown in FIG.

  A personal computer 10 shown in FIG. 1 is an information processing apparatus, and a display screen 14 is provided on the front surface of a main body 12. As shown in FIG. 4, the side cover 16 of the main body 12 of the personal computer 10 is provided with an opening 16a for incorporating an information storage device such as an optical disk drive device or a flexible disk drive device. The optical disk drive device and the flexible disk drive device may be optional components, and when these devices are not incorporated into the main body 12 of the personal computer 10, a dummy 18 is incorporated as shown in FIG. 4 to close the opening 16a. Specifically, by arranging the front plate 18a of the dummy 18 in the opening 16a, the opening 16a is closed in the same manner as when the optical disk drive device is incorporated. The optical disk drive device incorporated as an optional component is unitized and configured as a single unit, and the optical disk drive device may be hereinafter referred to as a unit.

  The dummy 18 is a part formed of a metal plate, imitating the shape of a unit incorporated in the main body 12. When the unit is assembled in the main body 12, the bracket 20 is usually mounted and fixed in the main body 12 after being attached and fixed to the bracket 20 which is a support member for supporting the unit. That is, the unit is assembled and fixed in the main body 12 via the bracket 20. The bracket 20 is configured so that a plurality of types of units can be attached, and even different types of units can be incorporated into the main body 20 via the same bracket 20.

  Therefore, when the dummy 18 is assembled into the main body 20, the dummy 18 (component) is first attached and fixed to the bracket 20 (support member), and then the bracket 20 is assembled into the main body 12 as shown in FIG. The bracket 20 is fixed to the main body 20 with screws or the like. As shown in FIG. 6, the bracket 20 is a structure formed of a metal plate, and includes a fixed portion 22 and a slide portion 24 that is a moving portion provided to be slidable with respect to the fixed portion 22. FIG. 7 is a plan view of the bracket 20 shown in FIG. 6 as viewed from above. FIG. 7A shows a state in which the slide part 24 as a moving part is pulled out from the fixed part 22, and FIG. 7B shows a state in which the slide part 24 is pushed into the fixed part 22.

  Two upright pieces 24 a are formed in the slide portion 24, and the upright pieces 24 a move relative to the fixed portion 22 as the slide portion 24 moves. A pin 24b, which is a protruding member, is fixed to each of the standing pieces 24a. The pin 24b is provided so as to protrude perpendicular to the upright piece 24a. Therefore, the protruding direction of the pin 24 b coincides with the moving direction of the slide portion 24. Two pins 22 b are also attached to the rear plate 22 a of the fixed portion 22, and the protruding direction of these pins 22 b also coincides with the moving direction of the slide portion 24.

  The dummy 18 is attached to the bracket 20 configured as described above. FIG. 8 is a perspective view showing the dummy 18 and the bracket 20 when the dummy 18 is attached to the bracket 20. The side plate 18b of the dummy 18 is provided with holes 18c at positions corresponding to the pins 22b and 24b of the bracket 20. The hole 18c is a through-hole formed by burring of a metal plate, and has an inner diameter that can receive the corresponding pins 22b and 24b. The hole 18c is not limited to a hole formed by burring, and may be a through hole formed by drilling, for example. Further, the hole 18 may not be a through hole as long as the pins 22b and 24b can be received.

  After the dummy 18 is placed on the bracket 20, the slide portion 24 of the bracket 20 is pushed toward the fixed portion 22, and the dummy 18 is attached to the bracket 20 as shown in FIG. 9. At this time, the upright piece 24a moves toward the dummy 18 as the slide portion 24 moves, and the pin 24b protruding from the upright piece 24a is inserted into the hole 18c provided in the side plate 18b of the dummy 18. At the same time, the pin 22 b provided on the rear plate 22 a of the fixing portion 22 of the bracket 20 is also inserted into the hole 18 c provided on the side plate 18 b of the dummy 18. Accordingly, the dummy 18 is sandwiched between the upright piece 24a of the bracket 20 and the rear plate 22b, and the pins 22b and 24b of the bracket 20 are inserted into the holes 18c of the dummy 18 to be attached and fixed to the bracket 20.

  FIG. 10 is an enlarged perspective view showing the vicinity of the upright piece 24a before the pin 24b is inserted into the hole 18c. When the dummy 18 is placed on the bracket 20, the pins 24 b of the upright pieces 24 a provided on the slide portion 24 of the bracket 20 are aligned with the holes 18 c provided on the side plate 18 b of the dummy 18. Therefore, when the slide part 24 is moved in the direction of the dummy 18, the pin 24b is inserted into the hole 18c. At this time, the pin 22b is also inserted into the hole 18c provided in the side plate 18b opposite to the dummy 18.

  FIG. 11 is a cross-sectional view showing a state where the pin 24b is inserted into the hole 18c. As shown in FIG. 11, a gap G1 is generated between the standing piece 24a and the side plate 18b of the dummy 18, and a gap G2 is generated between the pin 24b and the hole 18c. The gap G1 is a gap formed by the machining dimension tolerance of the dummy 18 and the bracket 20, and the gap G2 has an outer diameter of the pins 22b and 24b that is larger than an inner diameter of the hole 18c so that the pins 22b and 24b can be inserted into the hole 18c. In order to absorb the difference between the distance between the two pins 22b or 24b and the distance between the two holes 18c, the inner diameter of the hole 18c is made larger than the outer diameters of the pins 22b and 24b. This is because of the void. Since the gaps G1 and G2 are generated, rattling occurs between the dummy 18 and the bracket 20, and the dummy 18 vibrates and generates abnormal noise.

  Therefore, in the present embodiment, rattling of the dummy 18 is prevented by providing one sheet-like member in the gaps G1 and G2. The sheet-like member is a tape that is relatively easy to tear, and one having an adhesive material attached on one side is used. As shown in FIG. 12A, the sheet-like member 30 is pasted on the dummy 18 so as to cover the hole 18c, and the sheet-like member 30 is broken when the pin 24b (or 22b) is inserted into the hole 18c. Keep it like that. When the pin 24b (or 22b) breaks through the sheet-like member 30, the torn part of the sheet-like member 30 enters the hole 18c and fills the gap G2 as shown in FIG. 12 (b). By attaching the sheet-like member 30, the gap G1 is also filled.

  As the sheet-like member 30, a tape or sheet having a hardness or strength that allows the pins 24b (or 22b) to be easily broken through is used. As such a sheet-like member 30, it is preferable to use a cloth tape in which an adhesive material is attached to a woven fabric such as acetate cloth tape or cotton tape. Or the plastic tape which affixed the adhesive material on the plastic film like a vinyl tape can also be used. Or the rubber tape which affixed the adhesive material to the rubber sheet as mentioned later can also be used. Or what adhered the adhesive material to the gasket material may be used. The function necessary for the sheet-like member 30 is that it can be affixed to the surface of the dummy 18 and can be broken by the pins 24b (or 22b). It is not limited to.

  In this embodiment, as shown in FIG. 13, the sheet-like member 30 is affixed to a region where the hole 18c of the side plate 18b of the dummy 18 is provided so as to completely cover the hole 18c. The dummy 18 shown in FIG. 13 is shown with the dummy 18 shown in FIG. 8 turned upside down. 14A is an enlarged perspective view showing a region where the hole 18c of the dummy 18 is provided before the sheet-like member 30 is pasted, and FIG. 14B is a view after the sheet-like member 30 is pasted. It is a perspective view which expands and shows the area | region in which the hole 18c of the dummy 18 was provided. Since the hole 18c is provided at a position close to the back surface 18d, the sheet-like member 30 is pasted from the side plate 18b to the back surface 18d. However, as long as the sheet-like member 30 can be successfully attached, it is not always necessary to attach the sheet-like member 30 to the back surface 18d.

  After pasting the sheet-like member 30 so as to cover the hole 18 of the dummy 18, the dummy 18 is placed on the bracket 20, the slide portion 24 is moved, and the upright piece 24 a is moved toward the side plate 18 c of the dummy 18. Let As a result, the pin 22b opposite to the pin 24b of the upright piece 24a abuts against the sheet-like member 30 covering the hole 18c of the dummy 18, and the slide part 24 is further moved, whereby the pin 24b and the pin 22b are made into a sheet-like shape. It breaks through the member 30 and enters the hole 18c. At this time, the torn part of the sheet-like member 30 enters between the inner surface of the hole 18c and the pin 24b or the pin 22b. FIG. 15 is a perspective view showing the dummy 18 attached to the bracket 20 as described above. In the state shown in FIG. 15, the pin 24b (22b) is inserted into the hole 18c, and as shown in FIG. 12B, a part of the sheet-like member 30 is between the pin 24b (22b) and the inner surface of the hole 18c. I'm stuck in.

  The gap G2 shown in FIG. 11 is filled with the sheet-like member 30 that has entered between the pin 24b (22b) and the inner surface of the hole 18c, and the sheet-like member 30 is present between the dummy 18 and the bracket 20. Since the gap G <b> 1 shown in FIG. 11 is also filled, rattling of the dummy 18 is eliminated, and the dummy 18 is fixed to the bracket 20. Thereby, even if the bracket 20 vibrates, the dummy 18 does not rattle and no abnormal noise due to rattling occurs.

  In addition, even if a part of the sheet-like member 30 does not completely enter between the pin 24b (22b) and the inner surface of the hole 18c, even if it slightly enters as shown in FIG. There is an effect to suppress. Further, as shown in FIG. 17, even when the pin 24b (22b) is biased in the hole 18c, the sheet-like member 30 only needs to enter the one side.

  Further, when an elastic rubber sheet or the like is used as the sheet-like member 30, even if the sheet-like member 30 is not pierced, the sheet-like member 30 is deformed to cover the pins 24b, whereby the sheet-like member 30 24b and the inner surface of the hole 18c are inserted, and rattling of the dummy 18 can be prevented.

  As described above, according to the above-described embodiment, when the pins 24b and 22b (protruding members) attached to the bracket 20 (supporting member) are inserted into the holes 18c of the dummy 18 (components), the sheet-like member. 30 is pressed and deformed by the pins 24b and 22b (protruding members), so that a part of the sheet-like member 30 enters the hole, and a sheet-like shape is formed between the pins 24b and 22b (protruding member) and the inner surface of the hole 18c. A part of the member 30 is sandwiched. As a result, the pins 24b and 22b (protruding members) are fixed so as not to move in the hole 18c, and fixing without rattling is achieved. According to this embodiment, it is possible to achieve fixing without rattling with a simple structure in which the sheet-like member 30 is simply pasted so as to cover the hole 18c of the dummy 18 (component).

  In the above-described embodiment, the hole 18c is provided in the dummy 18 and the pins 24b and 22b are provided in the bracket 20. However, the holes and the pins are reversed, the pins are provided in the dummy 18 and the holes are provided in the bracket 20. Also good. That is, a pin may be provided on one of the dummy 18 and the bracket 20 and a hole may be provided on the other of the dummy 18 and the bracket 20 so that the pin is inserted into the hole.

  Further, in the above-described embodiment, the pin 24b and the pin 22b are provided on both the standing piece 24a and the rear plate 22a of the bracket 20, respectively, and the sheet-like member 30 is provided for the entire region of the hole 18c of the dummy 18 corresponding to these pins. However, it is not always necessary to provide the sheet-like member 30 for all of the holes 18c. For example, the sheet-like member 30 is attached only to the region of the hole 18c corresponding to the pin 24b provided in the two standing pieces 24a of the bracket 20, and the sheet is inserted into the hole 18c corresponding to the pin 22b provided in the rear plate 22a. Even if the shape-like member is left as it is, there is a sufficient effect of suppressing the rattling. In that case, the number of sheet-like members 30 is reduced, and the assembly process can be shortened.
