Description

  The present invention relates to an electronic device such as a mobile phone having a slide mechanism.

  As this type of electronic equipment, there are many foldable mobile phones and slide-type mobile phones on the market. The slide-opening mobile phone includes two parts that can slide linearly with respect to each other. One part includes a display unit for displaying an image or the like. The other part includes an operation unit that is opened and closed by sliding the one part.

  A spring for assisting these slides may be provided between the two parts. This spring is firmly fixed to the two parts at both ends. When the operation part is opened (closed) halfway by sliding, the operation part can be automatically slid and opened (closed) by the action of the spring thereafter. Therefore, when the slide is made linear between the two parts, the spring is always kept parallel to the two parts, so that it can be expected to effectively assist the slide.

  In a foldable mobile phone, it is easy to bring the mouth and the microphone close together during a call due to its structure. On the other hand, unlike a foldable mobile phone, a sliding open / close type mobile phone has a problem that the mouth and the microphone portion are likely to be relatively far apart during a call.

  Therefore, the inventors sought to develop a mobile phone that slides while the two parts curve so that the mouth and the microphone part approach each other during a call. At that time, it was found that the behavior of the spring provided between the two portions was different from the case of sliding linearly when sliding while curving. That is, when sliding while curving, the spring may be inclined with respect to the two portions. Therefore, if the spring is fixed in the same manner as in the case of sliding linearly while sliding while curving, the spring and the portion where the spring is fixed may interfere with each other, and smooth sliding may be hindered.

  Therefore, an exemplary problem of the present invention is to provide a slide opening / closing electronic device capable of avoiding interference of a spring for assisting a slide and realizing a smooth slide.

According to an exemplary aspect of the present invention, a first portion, a second portion that is slidable with respect to the first portion and that changes in angle with respect to the first portion before and after the slide, and A first fixing portion fixed to the first portion; a shaft portion protruding from the second portion; and a flange portion extending in a radial direction from the shaft portion and spaced from the second portion. Two fixing portions and a spring connected to the first and second fixing portions for assisting the slide, wherein the spring is engaged with the first fixing portion. An end portion and a second end portion engaged with the second fixing portion, the second end portion having a gap between the second portion and the flange portion, An electronic device can be obtained, which is arranged so as to be inclined with respect to the flange portion at an angle .
According to another exemplary aspect of the present invention, a first portion, and a second portion that is slidable with respect to the first portion and whose angle with respect to the first portion changes before and after the slide, A first fixing part fixed to the first part, a second fixing part having a fixing pin rotatable around an axis intersecting the second part, and the first and second parts And a spring for assisting the slide connected between the fixing parts, the fixing pin has an engaging part extending across an axis, and the spring is engaged with the first fixing part. And a second end portion rotatably engaged with the engaging portion, the second end portion having an angle with respect to the engaging portion. An electronic apparatus characterized in that it is arranged so as to be inclined can be obtained.

  ADVANTAGE OF THE INVENTION According to the exemplary aspect of this invention, the slide opening-and-closing electronic device which can avoid the interference of the spring for assisting a slide and can implement | achieve a smooth slide can be provided.

  With reference to FIG. 1 and FIG. 2, the structure of a slide openable mobile phone will be described first as an electronic apparatus according to an exemplary embodiment of the present invention.

  In FIG. 1, a slide open / close type mobile phone includes a display housing 1 and an operation housing 2 that slide open / close while curving. The display housing 1 includes a display unit 3 for displaying an image. The operation housing 2 includes an operation unit 4 having a plurality of buttons. The operation housing 2 includes an upper case 5 and a lower case 6 that are coupled to each other.

  In FIG. 2 showing an exploded view of the mobile phone, a slide unit portion 7 is provided between the display housing 1 and the operation housing 2. The slide unit portion 7 includes a rail plate 8 attached to the display housing 1, a frame 10 attached to the upper case 5 of the operation housing 2, and two sliders 9 attached to both ends of the frame 10. . When the rail plate 8 is engaged with the slider 9, the display housing 1 and the operation housing 2 can slide with respect to each other. Since the portion of the rail plate 8 that engages with the slider 9 is curved, when the mobile phone is opened and closed, it slides while curving. Each slider 9 is made of a slippery material in order to make the sliding operation smooth.

  The slide unit portion 7 further includes a spring 11 for assisting the slide. One end of the spring 11, that is, the first end portion 11 a engages with a first fixing pin 12 that functions as a first fixing portion fixed to the rail plate 8. The other end of the spring 11, that is, the second end portion 11 b engages with a second fixing pin 13 that functions as a second fixing portion fixed to the frame 10. Due to the presence of this spring 11, when the display housing 1 is opened from the slide closed state, it is automatically fully opened from the middle by the force of the contracted spring. Similarly, when the display housing 2 is closed from the slide open state, the display housing 2 is automatically fully closed halfway.

  Here, the display housing 1 and the rail plate 8 are collectively referred to as a first portion, and the operation housing 2, the slider 9, and the frame 10 are collectively referred to as a second portion. In this case, the first end 11 a of the spring 11 is attached to the first part by the first fixing pin 12, and the second end 11 b of the spring 11 is attached to the second part by the second fixing pin 13. It will be attached.

  With reference to FIG. 3, the attachment form of the spring 11 is demonstrated.

  The first fixing pin 12 has a shaft portion 12 a that protrudes from the rail plate 8, and a head portion or flange portion 12 b that extends in the radial direction from the shaft portion 12 a and is separated from the rail plate 8. The first end portion 11a of the spring 11 is sandwiched between the rail plate 8 and the flange portion 12b and engaged with the shaft portion 12a. Therefore, the first fixing pin 12 firmly fixes the first end portion 11 a of the spring 11.

  The second fixing pin 13 includes a shaft portion 13 a that protrudes from the frame 10, and a head portion or flange portion 13 b that extends radially from the shaft portion 13 a and is separated from the frame 10. The second end portion 11b of the spring 11 is disposed between the frame 10 and the flange portion 13b with an axial clearance and is engaged with the shaft portion 13a. Thus, the second fixing pin 13 loosely holds the second end portion 11b so as to allow the first end portion 11a of the spring 11 to freely move.

  With reference to FIG. 4 together with FIG. 3, the operation of the above-described slide openable mobile phone will be described.

  In the closed state of the mobile phone shown in FIGS. 3A and 3B, the spring 11 is substantially parallel to the flange portion 13 b of the second fixing pin 13 as shown in FIG. However, when the cellular phone shown in FIGS. 4A and 4B is opened, the spring 11 is inclined with respect to the flange portion 13b of the second fixing pin 13 at an angle as shown in FIG. become.

  If the spring 11 strongly hits the flange portion 13b of the second fixing pin 13, the slide opening / closing operation may not be smooth. However, here, by increasing the height of the second fixing pin 13, the flange portion 13 b of the second fixing pin 13 does not hit the spring 11 even when the spring 11 is inclined in the open state of the mobile phone. I have to. Therefore, a smooth opening / closing operation can be realized.

  In addition, since the first fixing pin 12 is low in height, the position of the spring 11 is stable, the spring 11 rattles against other parts such as a housing, the spring makes a rattling sound due to vibration, Such a problem does not occur.

  Further, it is preferable that a stabilizing member (not shown) such as a washer having a spring is provided in the axial clearance described above, and the position of the second end portion 11b of the spring 11 is elastically stabilized.

  The first fixing pin 12 may also hold the first end portion 11a loosely so as to allow the second end portion 11b of the spring 11 to freely move. In that case, the first end portion 11a of the spring 11 is disposed with an axial clearance between the rail plate 8 and the flange portion 12b of the first fixing pin 12, and the shaft portion of the first fixing pin 12 is provided. 12a is engaged.

  Another modification will be described with reference to FIGS. 3 and 4 as well as FIG.

  In FIG. 5, the second fixing pin 13 is fixed to the frame 10 so as to be rotatable as indicated by an arrow around an axis 14 that intersects the frame 10 and is preferably orthogonal. In this case, the second fixing pin 13 has a through hole 13b that intersects with the axis and preferably serves as an engaging portion extending perpendicularly. The second end portion 11b of the spring 11 is inserted into the through hole 13b and is rotatably engaged therewith. Thus, the second end portion 11b is loosely held so that the first end portion 11a of the spring 11 can freely move.

  A similar structure is also adopted between the first fixing pin 12 and the first end 11a of the spring 11, and the first end 11b of the spring 11 is allowed to move freely. The end 11a may be held loosely.

  Of course, the first fixing pin 12 may firmly fix the first end 11 a of the spring 11.

  In the above description, the mobile phone that slides while opening and closing has been described. However, as shown by the white arrows in FIG. The present invention can be similarly applied to any mobile phone having a slide mechanism in which an angle is generated.

  It goes without saying that various combinations of the above-described structures are possible.

  The present invention can be widely applied not only to mobile phones but also to other types of electronic devices such as video cameras and digital cameras.
