JP4871931B2 - Sliding mobile terminal - Google Patents

Description

  The present invention relates to a slide-type mobile terminal, and more particularly to a twist prevention structure when the mobile terminal is closed.

  Conventionally, a sliding mobile phone, which is a representative product of a sliding mobile terminal, has two housings, one housing is provided with a guide groove, and the other housing is provided with a slider. It is designed to slide in the groove.

  For example, in Patent Document 1, a lower plate coupled to a main body of a cellular phone is coupled to a cover portion of the cellular phone, the upper plate is slid relative to the lower plate, and one end of a first coil spring is connected to the lower plate by a first fixing pin. The other end is fixed to the upper plate by a second fixing pin, and the upper plate is slid with respect to the lower plate by the biasing force of the coil spring.

  As described above, as a driving force for sliding of a slide type mobile phone, an elastic member such as a torsion coil spring or a compression coil spring is generally used. In some cases, a plurality of springs are incorporated to reduce the thickness of the product. In a sliding portable terminal in which sliding movement is assisted by an elastic member, it is very difficult to apply an urging force completely parallel to the sliding direction with respect to the two housings. For this reason, there is a problem that the two housings are not able to be opened and closed in parallel and are rattling or inclined.

As in Patent Document 2, in a slide type mobile phone that is slidably connected to two housings via a slide mechanism, there is a problem that the two housings rattle due to a gap between the slider and the groove. In order to prevent such rattling between the two housings, the first housing is formed so that the outer surface and the inner surface of the upper housing penetrate the groove provided in the upper housing so that the slider can slide. And a second groove extending along the first groove in the longitudinal direction of the upper housing 1 and in which a projection for preventing rattling is slidably fitted. ing.

  However, the above-mentioned Patent Document 2 does not consider any gap between the slider and the groove in the rattling in the left-right direction. For this reason, especially when the first casing and the second casing are closed, the subtle displacement between the first casing and the second casing is noticeable due to the force of the elastic member. There is a problem of being bad.

  The present invention has been made in view of such a point, and an object of the present invention is to provide two housings without obstructing a sliding operation in a sliding portable terminal that assists sliding with a biasing member. This is to make it difficult for twisting and rattling to occur when closed.

  In order to achieve the above object, according to the present invention, a protrusion protruding in a direction perpendicular to the sliding direction is provided in the slider and the guide groove in which the slider is guided.

Specifically, in the first invention,
The first housing provided with a pair of guide grooves on the back side is slid onto the second housing provided with a pair of sliders for sliding in the guide grooves, and is configured to be freely opened and closed. Targets sliding mobile terminals.

And the sliding mobile terminal is
An urging member for assisting the sliding movement;
A first slider-side protrusion that protrudes perpendicularly to the direction of the slide on the side surface of the slider, and a protrusion amount in a direction perpendicular to the first slider-side protrusion is small, and a sliding amount of the first housing in the sliding direction A second slider-side protrusion is provided at a shorter distance than
A first guide groove-side protrusion is provided corresponding to the first slider-side protrusion so that the guide housing contacts the guide groove when the first housing and the second housing are closed. Corresponding to the two slider-side protrusions, a second guide groove-side protrusion having a larger protrusion amount in the vertical direction than the first guide groove-side protrusion is provided.

  According to the above configuration, when the first casing and the second casing are closed, the first guide groove side protrusion on the first casing side and the first slider side protrusion on the second casing side are in contact with each other. In addition, since the second guide groove side protrusion on the first housing side and the second slider side protrusion on the second housing side are in contact with each other, a force is applied in a direction inclined with respect to the sliding direction by the biasing member. Even if it works, the first casing and the second casing do not twist and do not wobble. Therefore, the first casing and the second casing are neatly overlapped and look good. Further, while the first housing slides with respect to the second housing, the moving first guide groove side protrusion passes the second slider side protrusion, but the first guide groove side protrusion protrudes. Since the amount is smaller than the protrusion amount of the second guide groove side protrusion, the second slider side protrusion that is in contact with the second guide groove side protrusion when closed is not in contact with the first guide groove side protrusion. For this reason, the sliding movement of the first housing is not hindered.

In the second invention, in the first invention,
The first and second guide groove side protrusions and the first and second slider side protrusions are provided at symmetrical positions.

  According to the above configuration, the left / right balance is improved by providing the left / right target positions.

In the third invention, in the first or second invention,
The biasing member is a torsion coil spring, one end of which is rotatably supported between the pair of guide grooves in the first casing, and the other end rotates between the pair of sliders in the second casing. Supported as possible.

  According to the above configuration, the force applied by the torsion coil spring is not completely parallel to the sliding direction, but the first and second guide groove sides when the first housing and the second housing are closed. Since the protrusion and the first and second slider side protrusions are in contact with each other, the first housing and the second housing are not twisted or wobbled.

In a fourth invention, in any one of the first to third inventions,
The slider is made of an elastic material that can be displaced in the vertical direction.

  According to the above configuration, when the first casing and the second casing are closed, the first casing is stabilized by the elastic force of the slider, and thus rattling and twisting are further prevented.

  As described above, according to the present invention, the first and second guide groove side protrusions and the first and second slider side protrusions that come into contact with each other when the first casing and the second casing are closed. Are provided in the guide groove of the first housing and the slider of the second housing so that they do not come in contact with each other during sliding, so that twisting and cracking can be prevented when the two housings are closed without obstructing the sliding operation. It can prevent rattling.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

-Mobile phone configuration-
1 to 3 show a mobile phone 1 as a sliding mobile terminal according to an embodiment of the present invention. The mobile phone 1 includes a first housing 3 having a display unit 2 on the front surface side. Further, the slide mechanism 6 is configured to be slidable on the second housing 5 having the operation unit 4. Accordingly, the cellular phone 1 is in a closed state in which the operation unit 4 illustrated in FIG. 1 is hidden on the back side of the first casing 3 by sliding the first casing 3 onto the second casing 5. And an open state in which the display unit 2 shown in FIG. 2 appears.

  The display unit 2 includes a liquid crystal display. The display unit 2 may include an organic EL display or may be configured with a touch panel. The display unit 2 occupies almost the entire first housing 3, but an operation key may be provided on a part of the first housing 3.

  As shown in FIG. 4, the operation unit 4 is provided from the upper and lower centers to the lower side of the second casing 5, and from the center to the upper side, a pair of rail-like sliders 7 protrude from the surface. Stands in parallel. The slider 7 is made of an elastic material that can be displaced in the left-right direction, for example, a synthetic resin material or a metal material. For example, the slider 7 is integrally formed with the second housing 5.

  On the other hand, as shown in FIG. 5, the slider 7 is fitted on the back side of the first housing 3, and a pair of guide grooves 8 for guiding the slider 7 sliding inside is parallel to each other. It is depressed. Stoppers 9 are provided at the upper and lower ends of each guide groove 8 to regulate the vertical sliding range L1 (shown in FIG. 3) of the slider 7 (first housing 3).

  As shown in FIGS. 6 to 10, in order for the slider 7 to slide smoothly in the guide groove 8, there is a gap C between the left and right inner surfaces of the slider 7 and the left and right inner walls of the guide groove 8. Is set. As shown in FIGS. 4 and 5, in order to prevent the mobile phone 1 from shaking in the thickness direction, the back surface upper protrusion 10 a and the back surface intermediate protrusion 10 b are formed on the back surface side of the first housing 3. And the back surface lower side protrusion 10c is provided. When the first housing 3 is closed, the front upper contact portion 11a is provided on the surface of the second housing 5 that the back upper projection 10a contacts, and when the first housing 3 is opened, the rear surface A front lower contact portion 11b is provided on the surface of the second housing 5 with which the lower protrusion 10c contacts.

  In addition, the cellular phone 1 includes a torsion coil spring 13 as an urging member that assists the sliding movement. The torsion coil spring 13 has one end 13 a rotatably supported by a back side spring support pin 14 between the pair of guide grooves 8 in the first housing 3, and the other end 13 b between the pair of sliders 7 in the second housing 5. The front side spring support pin 15 is rotatably supported.

  9 and 10, on the left and right outer surfaces of the lower end of the slider 7, there are formed first slider-side projections 7a that are perpendicular to the vertical sliding direction, that is, project to the left and right outer sides. . Similarly, second slider-side protrusions 7b are formed on the left and right outer surfaces at the upper end of the slider 7 so as to protrude outward in the left and right directions. The protrusion amount A1 of the first slider side protrusion 7a to the left and right outside is set to be larger than the protrusion amount A2 of the second slider side protrusion 7b (A1> A2). The vertical distance L2 between the first slider-side protrusion 7a and the second slider-side protrusion 7b is smaller than the entire slide amount L1 (L2 <L1).

  A first guide groove-side protrusion 8a that protrudes inward in the left-right direction corresponding to the first slider-side protrusion 7a is provided at the upper and lower intermediate positions of the guide groove 8. Similarly, a second guide groove side protrusion 8b is provided at the upper end of the guide groove 8 corresponding to the second slider side protrusion 7b. The first and second guide groove side protrusions 8a and 8b and the first and second slider side protrusions 7a and 7b are provided at symmetrical positions. The protrusion amount B2 of the second guide groove side protrusion 8b to the left and right inner side is larger than the protrusion amount B1 of the first guide groove side protrusion 8a (B2> B1). When the first casing 3 and the second casing 5 are closed, the first slider side protrusion 7a and the first guide groove side protrusion 8a come into contact with each other, and the second slider side protrusion 7b and the second guide groove side The protrusion 8b comes into contact with the protrusion 8b. That is, as a dimensional relationship, as shown in FIG. 9, A1 + B1 = A2 + B2.

-Action of mobile phone-
Next, the operation of the mobile phone 1 by the slide mechanism 6 constituted by the slider 7, the guide groove 8, and the torsion coil spring 13 will be described.

  When the mobile phone 1 is carried, it is carried in a closed state as shown in FIG. Various functions of the mobile phone 1 can be used even in this closed state.

  As shown in FIGS. 6 and 9, when the first housing 3 and the second housing 5 are closed, the biasing force is applied in the direction shown in FIG. Working, the first housing 3 tends to twist counterclockwise when viewed from the surface. However, the first guide groove side projection 8a on the first housing 3 side and the first slider side projection 7a on the second housing 5 side come into contact with each other, and the second guide on the first housing 3 side. Since the groove-side protrusion 8b and the second slider-side protrusion 7b on the second casing 5 abut against each other, even if a force acts in the direction inclined with respect to the sliding direction by the torsion coil spring 13, the first casing 3 and the second housing 5 do not wobble.

  For this reason, the first housing 3 and the second housing 5 are neatly overlapped and look good. Further, since the first and second guide groove side protrusions 8a and 8b and the first and second slider side protrusions 7a and 7b are provided at left and right symmetrical positions, the right and left balance is improved. Furthermore, since the first housing 3 is stabilized by the elastic force of the slider 7, rattling is further effectively prevented.

  Next, when using the operation unit 4 to make a call or the like with the mobile phone 1, it is necessary to open the first housing 3. As shown in FIGS. 7 and 10, when the first casing 3 is slid, the sliding movement of the first casing 3 is assisted by the action of the torsion coil spring 13. While the first casing 3 slides with respect to the second casing 5, the first guide groove-side protrusion 8a that moves upward passes the second slider-side protrusion 7b. Since the protrusion amount A1 of the groove-side protrusion 8a is smaller than the protrusion amount A2 of the second guide groove-side protrusion 8b, the second slider-side protrusion 7b that is in contact with the second guide groove-side protrusion 8b when closed is It does not contact the first guide groove side protrusion 8a. For this reason, the sliding movement of the first housing 3 is not hindered. 7A, the force of the torsion coil spring 13 is just balanced, but if this is exceeded, the slide is assisted in the direction of opening the first housing 3, and the front is the first. The sliding is assisted in the direction of closing the casing 3 of the first.

  When the first casing 3 is slid by the sliding amount L1 with the help of the torsion coil spring 13, the slider 7 comes into contact with the stopper 9 and the sliding movement is completed as shown in FIG. At this time, the urging force acts in the direction shown in FIG. 8A due to the action of the torsion coil spring 13, and the first casing 3 tends to twist counterclockwise when viewed from the surface. Then, because of the gap C provided to facilitate sliding, the first housing 3 that receives the force of the torsion coil spring 13 is slightly inclined with respect to the second housing 5. Is not conspicuous like the twist when the cellular phone 1 is closed, so that the appearance can be avoided.

-Effect of the embodiment-
Therefore, according to the mobile phone 1 according to the present embodiment, the first and second guide groove side protrusions 8a and 8b and the first guide groove side protrusions 8a and 8b that come into contact with each other when the first housing 3 and the second housing 5 are closed. And the second slider side projections 7a and 7b are provided in the guide groove 8 of the first housing 3 and the slider 7 of the second housing 5 so as not to come into contact with each other during the sliding, so that the sliding operation is not hindered. Twist and rattling can be prevented when the two casings 3 and 5 are closed.
