Description

  The present invention relates to a component fixing mechanism and an electronic device, and more particularly, to a component fixing mechanism and an electronic device improved in a component locking method.

  2. Description of the Related Art A housing that contains a container and a lid that covers the container, and stores equipment therein is known. For example, in the case of a personal computer (hereinafter referred to as “PC”), for example, a motherboard, a hard disk, a memory, a disk drive, a power supply, a video card, and the like are housed in a housing including a plastic lid and a container.

  In the case of a PC, a device such as a memory is often added or changed after purchase. Therefore, it is preferable that the housing has a structure that allows the lid to be easily opened. As a lock mechanism used in such a structure, for example, the structure shown in FIG. 1 is exemplified. 1A to 1C are diagrams illustrating an example of the configuration and operation of a component fixing mechanism in a conventional casing. In FIG. 1A, the component fixing mechanism is provided on the lid 110 of the housing, and moves along the lid 110 from the first position (right side in the figure) to the second position (left side in the figure) of the groove 115. The first fitting portion 121 and the second fitting portion 131 that are provided in the container 102 of the housing and can be fitted to the first fitting portion 121 are provided. The first fitting portion 121 includes a convex member 124. The second fitting portion 131 includes a concave member (132 + 133 + 134) into which the convex member 124 is fitted. The convex member 124 is fitted into the concave space 136, and the lid 110 is fixed (locked) to the container 102.

  In FIG. 1A, the lid 110 and the container 102 of the housing are separated from each other. The first fitting portion 121 is in the vicinity of the first position (right side of the drawing) of the groove 115. In FIG. 1B, the lid 110 is moved from the first direction A to the coupling position where the lid 110 and the container 102 are coupled. In FIG. 1C, the lid 110 is in the coupling position, and the first fitting portion 121 is moved from the first position (the right end in the figure) to the second position (the left end in the figure) of the groove 115, and the first fitting is performed. The convex member 124 of the joint portion 121 and the concave member (132 + 133 + 134) of the second fitting portion 131 are fitted.

  In the above case, the first fitting portion 121 is in the vicinity of the first position of the groove 115 in FIG. Accordingly, the lid 110 can be moved from the first direction A to the coupling position in FIG. That is, the movement of the side surface 125 of the convex member 124 is not hindered by the side surface 135 of the concave member (132 + 133 + 134). 2A to 2B are diagrams illustrating another example of the operation of the component fixing mechanism in the conventional casing. In the case of FIG. 2A, the first fitting portion 121 is in the vicinity of the second position (the left end in the drawing) of the groove 115. In this case, when the lid 110 is moved from the first direction A to the coupling position, the first fitting portion 121 hits the outside of the second fitting portion 131 as shown in FIG. That is, the side surface 125 of the convex member 124 is prevented from moving by the side surface 135 of the concave member (132 + 133 + 134), and the lid 110 cannot be moved to the coupling position.

  In recent years, PCs have come to be used by many people, and among them, there are many beginners and people unfamiliar with the handling of the case. When such a situation as shown in FIG. 2 occurs, those people may forcibly push the lid 110 against the container 102 and break the first fitting portion 121 and the second fitting portion 131. Such a problem in the housing is similarly observed not only in electronic devices such as PCs but also in other devices and apparatuses. Even when the position of the fixing member such as the first fitting portion 121 is not appropriate, a technique that enables the lid 110 and its container 102 to be fixed is desired.

  As a related technique, Japanese Patent Laid-Open No. 2000-3226 discloses a technique of a lid opening / closing device for a personal computer. This lid opening / closing device is provided with a main body in which a keyboard is arranged and a lid in which a display device is arranged on an inner surface while being rotatable between a closed position and an open position with respect to the main body. And a personal computer with It comprises first and second operation levers, first and second hook members, and transmission means. The first and second operation levers are provided on both side surfaces of the lid so as to be displaceable between a lock position and a lock release position. The first and second hook members engage with an engaging portion provided in the main body when the lid is in the closed position, lock the lid in the closed position, and the first and second operation levers. Due to this, it is displaced between the locked position and the unlocked position. The transmission means transmits the displacement force of one of the first operation lever and the second operation lever to the other operation lever.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a component fixing mechanism and an electronic apparatus according to the present invention will be described with reference to the accompanying drawings. In the present embodiment, a component fixing mechanism applied to a personal computer (PC) as an electronic device will be described, but it can also be attached to other devices.

  An embodiment of a component fixing mechanism of the present invention and a PC of the present invention to which the component fixing mechanism is applied will be described with reference to the accompanying drawings.

  First, the configuration of the embodiment of the PC of the present invention will be described. FIG. 3 is an external view from the front right showing the configuration of the embodiment of the PC of the present invention, and FIG. 4 is an external view from the left rear showing the configuration of the embodiment of the PC of the present invention. The PC 1 includes a PC main body 2 stored in a casing including a container 9 and a lid 10 covering the container 9, a keyboard 3 that can be stored in a lower space of the PC main body 2, a CD-ROM drive, a DVD drive, and an FD. A storage unit 4 storing a disk drive, a USB port, and the like, and a display 5 attached to the PC main body 2 are provided. FIG. 5 is an external view from the rear showing the configuration of the embodiment of the PC of the present invention. The lid 10 and the container 9 are provided with component fixing mechanisms 11, 12, and 13 and are fixed to each other.

  Next, the component fixing mechanisms 12 and 13 will be described in detail. FIGS. 6A to 6C are views showing the configuration and the first operation of the component fixing mechanism of the present invention. In FIG. 6A, the component fixing mechanisms 12 and 13 include a first fitting portion 21 provided on the lid 10 of the casing of the PC main body 2 and a first fitting portion 21 provided on the container 9 of the casing of the PC main body 2. 2 fitting portions 31. FIG. 6A shows a state where the lid 10 is removed from the container 9.

  The first fitting portion 21 includes an operation member 22, a main body member 23, and a convex member 24 that are integrally formed. The convex member 24 tapers as it moves away from the main body member 23. The side surface 25 forms a flat surface or a curved surface convex outward. It is preferably made of a material having a low coefficient of friction, or coated with a material having a low coefficient of friction, and a surface that is slippery with respect to other materials. The operation member 22 is movable from a position R (the right end of the groove 15 in FIG. 6A) of the groove 15 provided in the lid 10 to a position L (the left end of the groove 15 in FIG. 6A). . Accordingly, the first fitting portion 21 is moved from the first position (position of FIG. 6A) to the second position (FIG. 6C) along the lid 10 (in the direction of arrow D1 in FIG. 6A). ) Position).

  The second fitting portion 31 includes a return member 32 and a recess member 33 that are integrally formed. The return member 32 has a side surface 35 that forms a predetermined angle with respect to the direction of arrow A (or the surface of the container 9) in which the lid 10 in FIG. 6A is coupled to the container 9. The side surface 35 forms a flat or convex curved surface outward. It is preferably made of a material having a low coefficient of friction, or coated with a material having a low coefficient of friction, and a surface that is slippery with respect to other materials. The concave member 33 has a concave space 36 that opens in a direction perpendicular to the arrow A direction (or the surface of the container 9) and can fit a convex object. However, the return member 32 and the recessed member 33 may not be integrally formed as long as they are provided in the vicinity.

  Next, the operation of the component fixing mechanism of the present invention will be described.

First, the first operation of the component fixing mechanism of the present invention will be described with reference to FIGS.
6A, when the lid 10 is coupled to the container 9 by a user or an operator (hereinafter referred to as “user etc.”), the lid 10 is brought closer to the container 9 in the direction of arrow A. Then, the lid 10 reaches a coupling position as a position in contact with the container 9. This state is shown in FIG. At this time, the convex member 24 does not hit the second fitting portion 31 because the operation member 22 is at the position R (the first fitting portion 21 is at the first position).

  6B, the operation member 22 is moved from the position R to the position L by the user or the like. Accordingly, the first fitting portion 21 is moved along the lid 10 from the first position (position shown in FIG. 6A) to the second position (position shown in FIG. 6C). The convex member 24 is fitted into the concave space 36 of the concave member 33. This state is shown in FIG. Thereby, the 1st fitting part 21 and the 2nd fitting part 31 are couple | bonded, and the lid | cover 10 and the container 9 are fixed.

Next, the second operation of the component fixing mechanism of the present invention will be described with reference to FIGS. 7 (a) and 7 (b) and FIGS. 8 (a) to 8 (c). FIGS. 7A and 7B and FIGS. 8A to 8C are views showing a second operation of the component fixing mechanism of the present invention.
The state shown in FIG. 7A is basically the same as the state shown in FIG. However, FIG. 6A differs from FIG. 6A in that the operation member 22 of the first fitting portion 21 is not at the position R but at the position L. Accordingly, the first fitting portion 21 is not in the first position (the position in FIG. 6A) but in the second position (the position in FIG. 6C).

  In the state of FIG. 7A, when the lid 10 is coupled to the container 9 by the user or the like, the lid 10 is brought close to the container 9 in the direction of arrow A by the user or the like. However, since the operation member 22 is not at the position R but at the position L, the side surface 25 of the convex member 24 contacts the side surface 35 of the return member 32. Therefore, at this stage, the lid 10 cannot reach the coupling position as the position in contact with the container 9. This state is shown in FIG.

  In the state of FIG. 7B, the lid 10 is further pushed in the direction of arrow A by the user or the like. In that case, the pushing force P can be considered separately at a contact point between the side surface 25 and the side surface 35, a force P1 perpendicular to the side surface 35 and a force P2 parallel to the side surface 35. The force P1 is canceled by the effect of the return member 32. The side surface 25 slides on the side surface 35 by the force P2, and the convex member 24 moves along the side surface 35 (in parallel) in the lower right direction in FIG. That is, the 1st fitting part 21 moves to the arrow B direction in FIG.7 (b), while the lid | cover 10 approaches the container 9. FIG. Accordingly, the operation member 22 also moves from the position L toward the position R. This state is shown in FIG.

  In the state of FIG. 8A, the lid 10 is further pushed in the direction of arrow A by the user or the like. Due to the pushing force P, the first fitting portion 21 further moves in the direction of arrow B while the lid 10 further approaches the container 9. As a result, the first fitting portion 21 reaches the first position, and the operation member 22 reaches the position R. This state is shown in FIG.

  Since FIG. 8B and FIG. 8C are the same as FIG. 6B and FIG. 6C, respectively, description thereof is omitted.

  Regarding the side surface 35 of the return member 32, the angle formed by the side surface 35 and the arrow A direction is determined so that the force P2 in the drawing can move the first fitting portion 21 along the lid 10. Is preferred. The side surface 25 becomes easier to slide on the side surface 35 as the side surface 35 intersects at an acute angle with respect to the arrow A direction. However, if the angle is too acute, the original concave space 36 cannot be formed. Therefore, an acute angle within a predetermined range is preferable as the angle at which the force P2 becomes such a force. The range is determined by experiment or simulation.

According to the present invention, when the lid 10 and the container 9 in the casing are coupled and locked, the first fitting portion 21 that locks the lid 10 is not an appropriate position (position R) for attachment / detachment. Even in the locking position (position L: in the case of FIG. 7 (a)), it is only necessary to perform the same operation (the method described in FIG. 6) for locking the two parts as in the normal state. 1 fitting part 21 can be moved to an appropriate position (position R). As a result, the lid 10 and the container 9 can be directly coupled and locked.
That is, when two parts are joined, even if the position of one part is not the proper position for joining, only the normal joining operation is performed, the part moves to the proper position, and the joining operation is performed as it is. It becomes possible.

  In FIGS. 6, 7 and 8, the side surface 25 of the convex member 24 is a gently convex curved surface, and the side surface 35 of the return member 32 is a flat surface. However, the present invention is not limited to these. FIGS. 9A to 9C are diagrams showing other examples of the shape of the side surface of the convex member and the side surface of the return member. In the case of FIG. 9A, the convex member 24 is hemispherical, and its side surface 25 is spherical. The side surface 35 of the return member 32 is a flat surface. In the case of FIG. 9B, the convex member 24 is a circular cone (or half thereof: indicated by a broken line), and the side surface 25 is a side surface of a cone. The side surface 35 of the return member 32 is a side surface of a rounded curved surface (quarter cylinder). In the case of FIG.9 (c), the convex member 24 is hemispherical and the side surface 25 is spherical. The side surface 35 of the return member 32 is a gently convex curved surface.

  The side surface 25 and the side surface 35 are pressed against each other at the contact surface to form a contact surface having a predetermined area by the elasticity of the material of the convex member 24 and the return member 32. The area of the contact surface is preferably wide for reasons such as not concentrating the pressing force (P) in a small area, and facilitating delivery of the pressing force. That is, a predetermined lower limit exists for the area of the contact surface. On the other hand, it is preferably narrow for reasons such as reducing friction on the contact surface and making it easy to slide. That is, there is a predetermined upper limit for the area of the contact surface. Therefore, the curvatures of the curved surfaces of the side surface 25 and the side surface 35 are the elastic modulus of the material of the convex member 24 and the return member 32, the friction coefficient of the surface of the side surface 25 and the side surface 35, the magnitude of the assumed pressing force P, and the first fitting. Based on the slipperiness of the joint portion 21, it is determined by experiment or simulation so as to fall within the range of the area of the contact surface.

  The present invention can be applied not only in the case of attaching the lid 10 by a general user, but also in the operation of attaching the lid 10 to the container 9 in the assembly operation of the PC production process. In that case, when two parts are joined, even if the position of one part is not the proper position for joining, the operation of returning it to the proper position can be omitted. Then, only by performing a normal coupling operation, the part moves to an appropriate position, and the coupling operation can be performed as it is. Thus, the number of operations in the PC assembly work can be reduced, and the work efficiency can be improved.

  6, 7, and 8, the location where the lid 10 and the container 9 are coupled at a right angle has been described, but the present invention can be similarly applied to a location where they are coupled in parallel. This is shown in FIGS. 10 (a) to 10 (d). FIGS. 10A to 10D are views showing another configuration and third operation of the component fixing mechanism of the present invention. This is applied to the component fixing mechanism 11.

  10, the first fitting portion 21 and the second fitting portion are joined so that the second fitting portion 31 is joined to the container 9 on the return member 32 side, and the lid 10 and the container 9 are coupled in parallel. The difference from the case of FIGS. 6, 7 and 8 is that 31 is provided. However, the configuration and operation of the first fitting portion 21 and the second fitting portion 31 are the same as those in FIGS. 6 and 7. 10 (a), (b), (c), and (d) correspond to FIGS. 7 (a), (b), FIG. 8 (b), and (c), respectively. Is omitted.

  Also in this case, the same effect as in the case of FIGS. 6, 7 and 8 can be obtained.

  The present invention can be applied not only to the relationship between the lid and the container in the housing as described above but also to other members. One example will be described below. FIGS. 11A and 11B are views showing a crescent tablet to which the present invention is applied. The crescent lock is used for a glass door such as an aluminum sash, and includes a crescent main body 41 (FIG. 11A) and a crescent receiver 43 (FIG. 11B).

  The crescent main body 41 (FIG. 11A) is provided in a sash 51a (described later), and is rotatable from a first position (an unlocked position) to a second position (a locked position). A convex member 42 including a side surface 45 is provided. The crescent receiver 43 (FIG. 11B) includes a concave member 44 including a concave space 46 to which the convex member 42 is coupled, and a return member 47 having a side surface 48. The side surface 45 corresponds to the side surface 25 of the convex member 24 in FIG. The side surface 48 corresponds to the side surface 35 of the return member 32 in FIG. The conventional crescent body has a shape having a side surface M, but the crescent body 41 has a side surface 45. Accordingly, the return member 47 is pushed and rotated.

  12A to 12C are diagrams showing the operation of the crescent lock to which the present invention is applied. The crescent body 41 is attached to the sash 51a. The crescent receiver 43 is attached to a sash 51b that is paired with the sash 51a. And in Fig.12 (a), although the lock is not locked, the crescent body 41 is in the position where the lock is locked.

  At this time, when the sash 51a and the sash 51b are moved to a position where the glass door is closed and brought close to each other, the crescent body 41 and the crescent receiver 43 collide with each other. That is, the side surface 45 and the side surface 48 are in contact with each other. This state is shown in FIG. In the case of the conventional crescent lock, it stops as it is, and it is necessary to rotate the crescent main body 41.

  However, in the crescent lock to which the present invention is applied, the crescent body 41 rotates by bringing the sash 51a and the sash 51b closer to each other in the state shown in FIG. Thereby, the crescent body 41 is in the unlocked position. This is shown in FIG.

The rotation will be further described.
Figure 13 is a diagram showing a state of force in the case of contact between the crescent main body 41 and the crescent receiving 4 3. As crescent receiving 4 3 reaction force Q0 on Crescent body 41, crescent receiving 4 3 receives a force Q. The force Q can be decomposed into a force Q1 perpendicular to the side surface 45 and a force Q2 parallel to the side surface 45. At this time, the crescent body 41 can be rotated upward (in the unlocking direction) in the figure by the force Q2.

In this way, even when the lock is not locked, even if the crescent body 41 is in the position to lock the lock, the sash 51a or 51b is moved to the position where it is normally closed, so that the crescent body 41 can be in the unlocked position. Thereby, it can prevent that the crescent main body 41 and the crescent receptacle 43 collide, and the sash 51a, 51b will stop, or it will remove | deviate from a wheel. Further, it is possible to prevent the crescent body 41 and the crescent receiver 43 from colliding with each other and breaking. The crescent lock can bring the sash 51a closer to the return member 47 after the operation of opening the sash 51a.
That is, when two parts are joined, even if the position of one part is not the proper position for joining, the part moves to the proper position just by performing an operation like a normal joining operation, The coupling operation can be performed as it is.

  FIG. 14 is a diagram illustrating a lock mechanism in the cover of the storage unit 4. The storage unit 4 includes a cover 61, a lock mechanism 67, a pedestal 64, and a device 65. The cover 61 covers an area where the device 65 is stored. The lock mechanism 67 locks the cover 61 when the cover 61 is closed. The pedestal 64 fixes a part of the lock mechanism 67 to the PC main body 2. The device 65 is, for example, a CD-ROM drive, a DVD drive, an FD disk drive, a USB port, or the like.

  The lock mechanism 67 includes a convex member 62 and a concave member 63. The convex member 62 is provided on the cover 61. The cover 61 is provided at a position where it can be coupled to the recess member 63 when the cover 61 is closed. The recessed member 63 is fixed to the pedestal 64 so as to be movable up and down. The concave member 63 is coupled or removed by moving the upper and lower positions in the vertical direction (moving as indicated by arrows (alternate operation)) by the force applied to the convex member 62. The cover 61 is closed. Then, it can be coupled with the convex member 62. The concave member 63 is provided with a small switch (not shown) in the pedestal 64 for holding the position by the alternate operation.

When the user tries to open the cover 61 by hand, the user pushes the cover 61 downward once. Then, the convex member 62 moves downward, and thereby the concave member 63 is pushed downward, and the small switch is unlocked. Thereby, the concave member 63 moves upward and comes to a position where the convex member 62 is easily detached. The cover 61 is always applied with an upward force (direction in which the cover 61 is opened) by the elastic force of an elastic body such as a spring. Therefore, when the convex member 62 is easily detached, the convex member 62 is detached from the lock mechanism 67 and the cover 61 is opened.
On the other hand, when the user tries to close the cover 61 by hand, the user closes the cover 61 downward. Then, the convex member 62 moves downward and is inserted into the concave member 63. Thereby, the lower side of the concave member 63 is pushed by the convex member 62, and the concave member 63 moves downward and comes to a locked position. Then, the small switch is locked. Thus, the cover 61 is closed by the convex member 62 being locked by the concave member 63.
Therefore, when the user opens and closes the cover 61, it is necessary to perform an operation of pushing the cover 61 in both cases.

FIGS. 15A and 15B are cross-sectional views showing details of the locking mechanism. FIG. 15A shows a conventional lock mechanism 147. FIG. 15B shows a locking mechanism according to the present invention.
In the conventional locking mechanism 147 of FIG. 15A, the tip of the convex member 142 is strongly fixed to the concave member 143 because the tip of the convex member 142 is a rectangular parallelepiped. Therefore, when the user performs an operation of opening the cover 61, when the user performs an operation of lifting the cover 61 instead of a pressing operation, the convex member 142 cannot jump out while being fitted to the concave member 143. Accordingly, there is a high risk that the locking mechanism 147 may be broken due to an excessive force applied to the concave member 143.
On the other hand, the lock mechanism 67 of the present invention shown in FIG. 15B has a shape (wedge shape) in which the tip of the convex member 62 lies on a triangular prism with a short back. Therefore, since there is no upper corner portion of the convex member 62, locking is possible and there is no problem with the locking operation, but the fixing strength to the concave member 63 is suppressed as compared with the conventional case. Therefore, even when the user performs the operation of opening the cover 61, even when the user performs the operation of lifting the cover 61, an excessive force is not applied to the concave member 43, and the allowable range of the concave member 63 (the damage to the concave member 63 is not damaged). Due to the elastic deformation in a very small range), the lock mechanism 47 can be opened as it is without breaking. In that case, in order to restore the state of the small switch, it is only necessary to close the cover 61 once, lightly push the recessed member 63 to release it from the locked position, and close it again.
Thereby, damage and fatigue to the material of the lock mechanism can be reduced, and the life can be extended.
