Description

  The present invention relates to a portable electronic device having a storage space for storing an electronic component such as a battery in a housing and having a detachable lid that covers the storage space. The present invention relates to a portable electronic device in which a lid is difficult to drop even when an impact is applied.

  The mobile phone has a storage space for storing an electronic component such as a battery in a casing, and the storage space is covered with a lid.

  The lid is attachable to and detachable from the housing in order to attach or replace the electronic component. For example, in Patent Document 1, the lid is mounted by sliding it with respect to the casing, and in Patent Document 2, the lid is mounted on the casing by separately providing a locking knob or lever. .

Japanese Patent Laid-Open No. 10-255749 JP 2000-269655 A

When the cover is slid and mounted, the surface on which the housing and the cover slide relatively needs to be flat.Therefore, the slide surface has an uneven shape for arranging connectors, buttons, etc. I can't do it.
In addition, when a locking knob or lever is provided separately, the number of parts increases and the assembly of the device becomes complicated. Further, it is necessary to operate a locking knob or lever when attaching or detaching the lid, which is troublesome.

In view of this, there has also been proposed a portable electronic device in which a claw piece is provided on each end edge of the lid, and a concave portion in which the claw piece is fitted is formed in the casing. According to the portable electronic device, with the claw piece at one end fitted in the recess, the other end of the lid is pressed against the housing to deform the lid while deforming the other end. The lid can be attached to the housing by fitting the edge claw piece into the recess.
However, since the claw pieces are separated from both ends of the lid body, the lid body is easily rattled against the housing, and when the mobile electronic device is impacted by dropping or the like, the lid body is bent and the claw pieces are recessed. May come off and the lid may fall off the housing.

  An object of the present invention is to provide a portable electronic device in which a lid is not easily dropped even when an impact such as dropping is applied.

In order to solve the above problems, a portable electronic device according to the present invention is
A housing with a recessed storage space for storing electronic components;
A cover that covers the storage space and is detachably attached to the housing;
The lid includes a first end and a second end facing the first end, and a first engagement portion and a second engagement portion are provided at the first end and the second end, respectively. Have
In the portable electronic device having the first receiving portion and the second receiving portion that can engage the first engaging portion and the second engaging portion,
The lid has a curved portion that is bent toward the housing between the first end portion and the second end portion, and is directed toward the housing at a position sandwiching the first engaging portion and the bending portion. A third engaging portion formed,
The housing includes a third receiving portion with which the third engaging portion can be engaged.

After the lid is engaged with the second receiving portion, the lid is pushed toward the housing in a state where the third engaging portion is engaged with the third receiving portion, By bending and deforming the curved portion with the contact surface between the third engaging portion and the third receiving portion as a fulcrum, the first engaging portion engages with the first receiving portion, and the lid is attached to the housing. The
Further, in order to remove the lid from the housing, the first end is pulled in a direction in which the first engagement portion is detached from the first reception portion with the contact surface between the third engagement portion and the third reception portion as a fulcrum. Thus, it is only necessary to bend and deform the bending portion and remove the first engaging portion from the first receiving portion.

In the electronic apparatus according to the present invention, since the first engaging portion and the third engaging portion are provided with the bending portion interposed therebetween, the attachment / detachment of the lid body is restricted by the bending deformation generated only in the bending portion. Since the curved portion with a narrower region is less likely to bend and deform than the entire lid, once it is bent and deformed and attached to the housing, it can be difficult to remove, and the lid can be more firmly attached to the housing. .
Therefore, even if an impact such as dropping is applied to the lid body and the entire lid body is subjected to a bending deformation force, the force is dispersed throughout the lid body and does not concentrate on the curved portion. That is, since the bending deformation of the bending portion is small, it is difficult for the first engagement portion and the third engagement portion of the bending portion to be detached from the first receiving portion and the third receiving portion, and the lid body falls off from the housing. Can be prevented.

  Further, since the first engaging portion and the third engaging portion firmly fix the lid body to the housing at the first receiving portion and the third receiving portion at the bending portion, the lid body is attached to the housing at the time of mounting. Prevents rattling.

The side part and the lower part of the lid attachment surface (28) are curved toward the side edge and the lower edge. The lower curved portion of the lid attachment surface (28) is referred to as an internal curved portion (28a).

A plurality of receiving portions (21), (23), and (25) for attaching the lid (30) are formed on the lid attachment surface (28).
The receiving portions (21), (23), and (25) can have a concave shape. More specifically, as shown in FIGS. 4 and 6, the first concave portion provided at the lower end of the housing (20). (21), a second recess (23) provided above the storage space (27), and a third recess (25) provided between the first recess (21) and the second recess (23). be able to. The shape and arrangement of the recesses (21), (23) and (25) will be described later.

  A recess (29) for inserting a fingertip when the battery (41) is removed is formed below the storage space (27), following the storage space (27).

  As shown in FIG. 6, inside the housing (20) composed of the front half (20a) and the latter half (20b), control of the antenna (42) for signal transmission / reception and other cellular phones (10), An electronic component (44) necessary for communication and the like is accommodated.

As shown in FIGS. 1 to 3, 5, 6, etc., the lid body (30) is detachable from the lid body mounting surface (28) of the housing (20). The lid (30) can be formed by integrally molding a resin.
The lid (30) is formed in a shape that is smoothly continuous with the latter half (20b) when the exterior is mounted, and the first end (30a) serving as the lower end of the lid (30) and both sides of the lid (30) Is bent towards the housing (20). The bent portion on the first end portion (30a) side is referred to as a curved portion (39).
As shown in FIG. 8, the curved portion (39) is curved in a substantially coincident shape so as to follow the internal curved portion (28a) of the lid mounting surface (28).

As shown in FIGS. 5 and 6, the lid (30) has a plurality of receiving portions (21) (23) (25) formed on the lid mounting surface (28) at the first end (30a). Have engaging portions (31), (33) and (35), respectively.
When the receiving portions (21), (23), and (25) have a concave shape, the engaging portions (31), (33), and (35) can have a protruding shape, more specifically, the engaging portions. The first protrusion (31) that fits into the first recess (21), the second protrusion (33) that fits into the second recess (23), and the third protrusion that fits into the third recess (25) (35).

  The first protrusion (31) protrudes inward from the vicinity of the first end (30a). In the embodiment shown in the drawing, the first protrusion (31a) is spaced at two locations on the left and right sides of the first end (30a). A first protrusion (31) is formed. As shown in FIG. 8, each first protrusion (31) is formed such that the first contact surface (32) that contacts the first recess (21) faces obliquely upward.

  The second protrusion (33) has an insertion piece (33a) that extends inside the upper end that becomes the second end (30b) of the lid (30) and has a tip bent upward. In the illustrated embodiment, the second protrusion (33) is formed at the center of the second end (30b) and at three locations on the left and right.

  The third protrusion (35) is provided at a position sandwiching the bending portion (39) with respect to the first protrusion (31). More specifically, it is desirable that the third protrusion (35) is disposed at an upper position along the lid (30) with respect to the first protrusion (31). Thereby, when the protrusions (31) and (35) are engaged with the recesses (21) and (25), the lid (30) can be more easily removed from the housing (20).

  As shown in FIG. 8, each third protrusion (35) has a third contact surface (36) that contacts the third recess (25) so that it is substantially parallel to the first contact surface (32). It is desirable to form. More specifically, as shown in FIG. 8, when the first contact surface (32) is formed obliquely upward, the third contact surface (36) is also formed so as to face obliquely upward.

In addition, the lid (30) has a recess (37) for inserting the fingernails of the operator to pry open when removing the lid (20) between the first protrusions (31), (31). Is formed. The dent (37) can be exemplified by a shape of a groove that is long in the left-right direction or a shape that is opened through.
In addition, a notch (38) is formed on the side edge of the lid (30) corresponding to the protruding portion (20c) provided on the side edge of the latter half (20b).

The recesses (21), (23), and (25) provided in the aforementioned housing (20) are formed at positions where the above-described protrusions (31), (33), and (35) can be engaged.
More specifically, as shown in FIG. 4, the first recess (21) that engages with the first protrusion (31) is recessed on the lower end side of the housing (21). As shown in FIGS. 6 and 8, the first recess (21) has the first contact surface (22) on the side that contacts the first contact surface (32) of the first protrusion (31) facing obliquely downward. It is formed as follows.

  The second recess (23) that engages with the second protrusion (33) is recessed near the upper end of the lid attachment surface (28). As shown in FIG. 6, the second recessed portion (23) has a locking portion (24) protruding downward from which the insertion piece (36) at the tip of the second protruding portion (33) is hooked.

  The third recess (25) engaged with the third protrusion (35) is formed at an upper position along the internal bending portion (28a) of the housing (20) with respect to the first recess (21). In the illustrated embodiment, the third recess (25) is formed continuously to the storage space (27). As shown in FIGS. 6 and 8, the third recess (25) has a third contact surface (26) on the side that contacts the third contact surface (36) of the third protrusion (35) obliquely downward. It is formed to face.

  In the mobile phone (10) configured as described above, the lid (30) is attached to the housing (20) in the following manner.

  First, hold the lid (30) so that the second end (30b) is inclined toward the housing (20), and align the second protrusion (33) with the second recess (23). The insertion piece (36) of the second protrusion (33) is inserted into the second recess (23). Next, the lid body (20) is slid slightly upward as it is, and the insertion piece (36) is hooked on the locking portion (24) of the second recess (23).

  Next, by pressing the lid (30) so that the first end (30a) approaches the housing (20), as shown in FIG. 7, the third protrusion (35) becomes the third recess (25 ).

  In this state, the lid (30) is inclined with respect to the housing (20). The bending portion (39) is bent, and the first protrusion (31) and the third protrusion (35) formed with the bending portion (39) in between are the first contact surface (32) and the first protrusion (32). Since the three contact surfaces (36) are provided so as to be substantially parallel, the first protrusion (31) does not fit into the first recess (21) as shown in FIG. The tip of one recess (21) is in contact with the inner curved portion (28a) of the lid attachment surface (28).

  Accordingly, the first end (30a) side of the lid (30) is further strongly pressed in the direction of arrow A in FIG. As a result, the lid (30) has the first protrusion with the third contact surface (26) (36) as a fulcrum in a state where the third protrusion (35) is in contact with the third recess (25). The tip of (31) moves along the internal bending portion (28a), and is bent and deformed so that the bending portion (39) spreads.

As a result, as shown in FIG. 8, the first protrusion (31) gets over the lower end of the lid attachment surface (28) and fits into the first recess (21).
Thus, the lid (30) has the first protrusion (31) as the first recess (21), the second protrusion (33) as the second recess (23), and the third protrusion (35) as the third. The lid (30) is attached to the housing (20) while being fixed in a state of being fitted in the recess (25).

  More specifically, the movement of the lid (30) in the vertical direction of the casing (20) is performed by the first protrusion (31), the first recess (21), the second protrusion (33), and the second recess ( 23) and is regulated by the engagement of the third protrusion (35) and the third recess (25). Therefore, the lid (30) does not rattle up and down with respect to the housing (20).

  Further, the rearward movement of the lid (30) relative to the housing (20) is caused by the relationship between the first protrusion (31) and the first recess (21), and the second protrusion (33) and the second recess (23). Therefore, the lid (30) does not come off rearward with respect to the housing (20).

  However, the lid (30) can be firmly attached to the housing (20) without rattling.

  Since the curved shape of the curved portion (39) of the lid (30) and the internal curved portion (28a) of the lid mounting surface (28) are substantially the same, the lid (30) is attached to the housing (20), In a state where the first protrusion (31) is fitted in the first recess (21), the bending deformation of the bending portion (39) is released, and no bending force remains in the bending portion (39).

  From the state in which the lid (30) is mounted on the housing (20), the operator's fingernail or the like is inserted into the recess (37) formed in the curved portion (39), and the lid in the direction of arrow B in FIG. By pulling (30), the lid (30) can be removed from the housing (20). More specifically, in the lid body (30), the curved portion (39) is bent and deformed in the direction of arrow B, and the first protrusion (31) is disengaged from the first recess (21). When the lid (30) is further pulled up in the direction of arrow B in this state, the third protrusion (35) is then detached from the third recess (25), and the second protrusion (33) is further moved to the second recess (23 ).

  When the lid (30) is pulled in the direction of arrow B, the vertical movement of the lid (30) is restricted by the engagement between the third protrusion (35) and the third recess (25). The That is, a tensile force acts on the entire lid body (30) and the entire lid body (30) is not flexed and deformed, but only the bending portion (39) is flexed and deformed in the direction of expanding the curvature. Therefore, even when the same tensile force is applied, the bending amount of only the bending portion (39) is smaller than the total bending amount of the flexible lid (30), and therefore the first protrusion (31 ) Is required to be removed from the first recess (21). Therefore, it is difficult to remove the lid (30).

  The same can be said when the cellular phone (10) is dropped and subjected to an impact. That is, even when the lid (30) is bent and deformed by an impact such as dropping, if the mobile phone (10) of the present invention, the bent portion (39) of the lid (30) is greatly bent. As long as the deformation force does not act, the first protrusion (31) does not come off the first recess (21). Therefore, the mobile phone (10) can be provided in which the lid (30) is unlikely to fall off the housing (20) even when subjected to an impact such as dropping.

  In the above description, the first engaging portion (31), the second engaging portion (33), and the third engaging portion (35) are the protrusions, the first receiving portion (21), and the second receiving portion (23). The third receiving portion (25) has a concave shape, but any or all of the irregularities can be formed in reverse. Further, it is obvious that the positions and the number of the engaging portions (31), (33), (35) and the receiving portions (21), (23), and (25) are not limited to the above embodiments. Of course, additional engaging portions and receiving portions may be provided in addition to these engaging portions and receiving portions. For example, an engaging part and a receiving part can be further arranged on the side surfaces of the lid (30) and the housing (20).

  Further, in this embodiment, the lid (30) is configured to cover a part of the rear surface of the housing (20), but may be configured to cover the entire rear surface of the housing (20). In this case, the first engaging portion (31) and the third engaging portion (35) can be provided on one or both of the lid (30), and the bending portion (39) It is also possible to form both. When these are provided on both the lids (30), the above-described second engagement portion (33) may be the first engagement portion (31).

According to the cellular phone (10) of the present invention, since a lock knob and lever are not separately provided, the number of parts is not increased and the trouble of attaching and detaching is eliminated, and the cover with a relatively simple structure by integral molding is provided. The body (30) can be firmly attached to the housing (20).
In addition, the connector (50) and buttons for external connection can be arranged on the side of the lid (30) and the housing (20) facing each other to adopt an uneven shape, reducing various design constraints. And design variations can be increased.

  Note that the shape of the cellular phone (10) and the method for attaching and detaching the lid (30) are not limited to the above, and the present invention can of course be applied to, for example, a folding portable electronic device. .

  INDUSTRIAL APPLICABILITY The present invention is useful as a portable electronic device in which a lid body does not easily drop even when an impact such as dropping is applied.
