[0011]
The lower cover 5 has a recess 6 in which an HDD assembly 8 as a unit product can be incorporated on the outer surface, and the recess 6 can be closed with a lid 9.
[0012]
More specifically, the HDD assembly 8 includes an HDD unit 10 and a bracket 12 that covers the outer surface of the HDD unit 10 and is fixed to the one surface 10a with a fixing screw 11. Among these, the bracket 12 is bent at a substantially right angle from the main body 12a along the front surface 10b of the HDD unit 10 and the main body 12a fixed by the fixing screw 11 along the one surface 10a of the HDD unit 10. A front wall portion 12b, left and right side wall portions 12c that are bent at substantially right angles from the main body portion 12a along the left and right side surfaces of the HDD unit 10, and a right angle from the main body portion 12a along the rear surface 10c of the HDD unit 10. The rear wall portion 12d that is bent is integrally formed with a locking claw portion 12e that is bent at a substantially right angle toward the rear from the lower end of the rear wall portion 12d. In addition, a pair of rectangular lock holes 13 are formed on the left and right sides of the corner portion where the front wall portion 12b is bent from the main body portion 12a.
[0013]
The lower cover 5 will be further described. The concave portion 6 of the lower cover 5 has a sufficient space for accommodating the HDD assembly 8, and a lock hole 13 on the HDD assembly 8 side from the bottom surface 6a. The pair of locking pieces 14 are integrally formed so as to protrude toward the opening side. A locking claw 14a that can be engaged with the lock hole 13 is integrally provided at the tip of each locking piece 14 as shown in FIG. A pair of lock holes 15 are formed on the inner surface 6 b of the recess 6 facing the locking piece 14 so as to correspond to the locking piece 14. Further, a slit 16 is formed in the inner surface 6c of the recess 6 facing the inner surface 6b corresponding to the locking claw portion 12e of the HDD assembly 8 at the left and right central portions. Thus, the lock piece 17a of the lock plate 17 is disposed in a state in which the lock piece 17a protrudes from the inner surface 6c at a substantially right angle into the recess 6. The lock plate 17 is fixed to the lower cover 5, and a part 17b is cut and raised at the tip of the lock piece 17a as shown in FIG. A portion 18 is formed, and a locking claw portion 12e is inserted into the notch 18 so as to be engageable.
[0014]
The lid 9 is formed of the same resin material as the lower cover 5, and has a main body portion 9 a that covers the opening of the recess 6, and a pair of latches corresponding to the lock hole 15 on the lower cover 5 side on the back surface side of the main body portion 9 a. The piece 19 is divided into left and right parts (see FIG. 7). A locking claw 19 a that can be engaged with the lock hole 15 is integrally provided at the tip of each locking piece 19, and a locking surface 19 b of the locking claw 19 a is engaged with the lock hole 15. When the locking piece 19 is pulled strongly in the detaching direction after being joined, it is formed as a tapered surface so that the engagement can be forcibly released.
Further, stopper ribs 20 are formed integrally with the back surface side of the main body 9 so as to correspond to the back surface side of the locking pieces 19 and extend substantially parallel to the locking pieces 19 (see FIG. 7). The stopper rib 20 and the locking piece 19 can be inserted substantially in the gap between the inner surface 6 b of the recess 6 and the locking piece 14 in the lower cover 5. Among these, the stopper rib 20 functions as a member for preventing the locking piece 19 from falling toward the inner surface 6b side. On the other hand, on the end portion side opposite to the end portion side where the locking piece 19 of the main body portion 9 is formed, it is inserted into the slit 16 on the lower cover 5 side and engaged with the end surface 16a. A letter-shaped locking claw 21 is formed integrally with the main body 9a.
[0015]
8 to 10 are diagrams showing the assembling operation of the HDD assembly 8. Accordingly, the operation of assembling the HDD assembly 8 will be described with reference to FIGS. In the following description, it is assumed that the lid 9 is removed and the HDD assembly 8 is not yet set in the recess 6 of the lower cover 5.
[0016]
First, the HDD assembly 8 is set in the recess 6. When the HDD assembly 8 is set, the entire HDD assembly 8 is inclined with the rear wall portion 12d side down, and the locking claw portion 12e of the bracket 12 is moved to the lock plate 17 on the lower cover 5 side. The engaging claw portion 12e is engaged with the back side of the lock plate 17, and the front wall portion 12b side is dropped into the recess 6 in this engaged state (see FIG. 8). Then, the bracket 12 comes into contact with the locking claw 14a of the locking piece 14 in the middle, but the outer surface 14b of the locking claw 14a here is formed in a taper shape, and this locking shape causes the locking piece 14 to be outside. The force that escapes to the (inner surface 6b side) is received from the HDD assembly 8 side and is elastically deformed outward to allow the HDD assembly 8 to further enter the recess 6. When the HDD assembly 8 is dropped until it is in close contact with the bottom surface 6 a of the recess 6, the lock hole 13 of the bracket 12 corresponds to the lock claw 14 a, and the lock claw 14 a is inserted into the lock hole 13. The locking piece 14 is elastically restored to the state of being engaged and locked (see FIGS. 5 and 9). As a result, the HDD assembly 8 is secured to the recess 6 by being engaged with the locking claw portion 12e and the lock plate 17 and by being engaged with the locking claw 14a and the lock hole 13.
[0017]
Next, a lid 9 is attached to the lower cover 5 to hide the HDD assembly 8 in the recess 6. When the lid 9 is attached to the lower cover 5, the lid 9 is inclined with the side on which the locking claw 21 is formed facing down, and the locking claw 21 is placed in the slit 16 on the lower cover 5 side. The engaging claw 21 is engaged with the end face 16a, and then the lid 9 is dropped into the recess 6 in this engaged state (see FIG. 9). Then, the locking piece 19 and the stop rib 20 are dropped in a state of entering between the inner surface 6 b of the recess 6 and the locking piece 14. In the middle of this, the locking claw 19b of the locking piece 19 abuts against the opening edge of the recess 6. However, the outer surface 19c of the locking claw 19b here is formed in a taper shape. The stop piece 19 receives a force to escape inward (stop rib 20 side) and is elastically deformed inward to escape, thereby allowing the locking piece 19 to enter the recess 6. When the lid 9 is dropped to the state where the opening of the recess 6 is closed, the locking claw 19a corresponds to the lock hole 15, and the locking claw 19a is inserted into the lock hole 15 and locked. The locking piece 19 returns elastically to the state. Further, in this state, the stop rib 20 is disposed in a state of being in close contact with the back surface (the inner surface 6b side) of the locking piece 14 (see FIGS. 1 and 10). As a result, the lid 9 is prevented from coming off by the engagement of the locking claw 21 and the end surface 16a and the engagement of the locking claw 19a and the lock hole 15, and the lower cover 5 is closed to the opening surface of the recess 6. Fixed.
[0018]
Therefore, the mounting of the HDD assembly 8 to the electronic device 1 is completed, and the gap 19 is closed between the inner surface 6b of the recess 6 and the locking piece 14, and the locking piece 19 and the stop piece. The ribs 20 are arranged. In this state, the electronic device 1 is subjected to vibration from the outside, for example, a force is applied to the HDD assembly 8 to move in the direction of arrow B in FIG. 1, and a force is also applied to the locking piece 14 in the direction of arrow B. In such a case, since the stop rib 20 is disposed on the back side of the locking piece 14, the stop rib 20 serves as a stopper to prevent the locking piece 14 from being bent in the arrow B direction. The claw 14a and the lock hole 13 are prevented from coming off. The force in the direction of arrow B is also transmitted to the locking piece 19 on the lid 9 side via the stop rib 20 and presses the locking piece 19 against the inner surface 6b, so that the locking claw 19a engages with the lock hole 15. Prevents you from losing. Therefore, in this structure, even if the HDD assembly 8 tries to move in the direction of arrow B in FIG. 1 due to external vibration from the electronic device 1, the HDD assembly 8 and the lid 9 are not easily removed. .
[0019]
Next, the case where the HDD assembly 8 needs to be replaced and the HDD assembly 8 is removed will be described. In this case, a force is applied to the lid 9 to pull the end of the lid 9 on the side where the locking piece 19 is formed to the outside. Then, since the locking surface 19b of the locking claw 19a is formed as a taper surface, the locking piece 19 is elastically deformed inward (stop rib 20 side) by the force with which the lid 9 is pulled and escapes. Can be lifted. Next, when the latching claw 21 is removed from the slit 16, the lid 9 can be removed from the lower cover 5, whereby the HDD assembly 8 is exposed in the recess 6.
[0020]
Next, the locking piece 14 is tilted to the inner surface 6b side of the recess 6 to remove the locking claw 14a from the lock hole 13, and in this state, one side of the HDD assembly 8 close to the locking piece 14 is lifted up. Next, when the locking claw 12 e of the bracket 12 is extracted from the notch 18 of the lock plate 17, the HDD assembly 8 can be removed from the recess 6. Then, replacement is completed by incorporating a new HDD assembly 8 as described above.
[0021]
Therefore, in the structure of this embodiment, the HDD assembly 8 can be easily attached without using screws or the like used in the conventional structure.
Moreover, even if the lower cover 5 is not removed, the replacement work can be easily performed by simply removing the lid 9.
Furthermore, since the locking piece 19 and the stop rib 20 are disposed in a state in which the gap between the inner surface 6b of the recess 6 and the locking piece 14 is closed, the lid 9 is closed. In addition, the lid 9 and the HDD assembly 8 can be prevented from being easily removed.
[0022]
In the present embodiment, the case where the HDD assembly is composed of the HDD unit 10 and the bracket 12 has been described. However, this can also be applied to the case where the HDD unit 10 is directly assembled in the recess 6. The same effect can be expected when the present invention is applied not only to the assembly 8 but also to a case where a unit product that needs to be replaced, such as a battery unit, is attached to the electronic device 1.
[0023]
【The invention's effect】
As described above, according to the present invention, since the unit product can be easily attached to the electronic device side without using screws or the like used in the conventional structure, the unit can be easily replaced. . Moreover, since the unit can be easily replaced by simply removing the lid, workability is improved.
Furthermore, even if the device side locking piece is pressed from the unit product side due to external impact, etc., the deformation deformation is suppressed by the stop rib, and the unit product side locking hole and the device side locking claw Since the engagement is difficult to disengage, it can be expected that the lid and the unit product can be easily prevented from coming off.
