Description

  The present application relates to a display device having a waterproof structure.

  Conventionally, some electronic devices are provided with a waterproof structure that prevents water from entering the casing of the electronic device in consideration of outdoor use. In general, an electronic device having such a waterproof structure is provided with a display lamp for displaying an operation state of the electronic device in a casing, and the display lamp portion is also waterproof. Since the display lamp performs display by guiding light from a light emitting element such as a light emitting diode (LED) provided inside the housing to the outer surface of the housing using a light guide member, the waterproof structure has a light guide structure. It is provided between the member and the housing. For example, Patent Document 1 discloses a waterproof structure in which an adhesive is applied to the inside of a hole opened in a housing through which the light pipe passes when light emitted from an LED is guided to the outside of the housing with a light pipe. Yes.

  On the other hand, in an electronic device, there is a waterproof structure in which waterproofing between a light guide member and a housing is performed with a double-sided tape. Here, a waterproof structure of a comparative technique using a double-sided tape will be described with reference to FIGS. 1 to 3 by taking a display device such as a tablet as an example.

  FIG. 1A shows the display device 1 having the image display unit 4 on the upper side as viewed from the display unit 4 side, and FIG. 1B shows the display device 1 shown in FIG. It is seen from the lid 5 side. The housing 2 of the display device 1 is generally provided with several display lamp units 3 for displaying the operation state, the charging state, and the like of the display device 1. In the display device 1 of this example, the display lamp unit 3 is provided on one side surface 2S of the housing 2, and there are three lamps (indicators). In some cases, a light emitting element such as an LED is directly attached to the display lamp unit 3, but in general, light emitted from the light emitting element mounted on a circuit board built in the display device 1 is enclosed by a light guide member. The display is performed by guiding to the side surface 2S of the body.

  Here, a comparative technique for guiding light emitted from a light emitting element mounted on a circuit board built in the display device 1 to the side surface 2S of the housing using a light guide member will be described. FIG. 2A shows the inside of the housing of the display lamp unit 3 provided on the side surface 2S of the housing 2 of the display device 1 shown in FIG. The display lamp portion 3 provided on the side 2S surface of the display device 1 shown in FIG. 1B has three display lamps, and a through-hole for inserting the light guide member 6 inside the housing. 2H is provided in three places. The light guide member 6 is usually formed as a lens light guide component 8 including a mounting plate 7, and the three light guide members 6 are fixed to the mounting plate 7 at the same intervals as the three through holes 2H. The lens light guide component 8 provided with the mounting plate 7 can be formed by insert molding in which a resin is injected while the light guide member 6 is placed in a mold.

  2B, the light guide members 6 of the lens light guide component 8 shown in FIG. 2A are inserted into the through holes 2H, respectively, and the mounting plate 7 is fixed to the side surface 2S of the housing 2 to guide the lens. The state in which the component 8 is attached to the side surface 2S of the housing 2 is shown. When the state in which the lens light guide component 8 is attached to the side surface 2S of the housing 2 is viewed from the outside of the housing 2, as shown in FIG. 3A, the distal end of the light guide member 6 from the side surface 2S of the housing 2 The part is exposed.

  FIG. 3B shows a portion X in FIG. 1B when the lens light guide component 8 of the comparative technique is mounted inside the display lamp portion 3 in the display device 1 shown in FIG. The cross section in is shown. In the cross-sectional view shown in FIG. 3B, only necessary portions are hatched.

  However, in the display device 1 to which the lens light guide component 8 of the comparative technique is attached, when the lens light guide component 8 is fixed to the housing 2, the mounting plate 7 is waterproof on both sides from the viewpoint of the waterproof specification of the display device 1. The tape 17 is watertightly attached around the through hole 2H of the housing 2. A sealing material may be used instead of the double-sided tape 17. For this reason, in order to obtain the waterproof performance of the waterproof double-sided tape 17, the display device depends on the width of the mounting plate 7 around the through-hole 2H of the housing 2 and the thickness of the waterproof double-sided tape 17. There is a problem that the height of 1 increases.

  Further, in the structure shown in FIG. 3B, a support member that supports the lens light guide component 8 inside the housing 2 against the water pressure that pushes the lens light guide component 8 inward when the display device 1 is submerged is necessary. However, there is a problem that the internal space of the apparatus is limited and it is difficult to install the support member.

  Hereinafter, embodiments of the present application will be described in detail based on specific examples with reference to the accompanying drawings. Note that members other than the lens light guide component used in the display device of the present application that are also used in the display device using the lens light guide component of the comparative technique are described with the same reference numerals. .

  As a specific example of the display device of the present application, a waterproof specification display device 1 such as a tablet shown in FIGS. 1A and 1B will be described. That is, in the display device 1 shown in FIGS. 1A and 1B, the light emitted from the light emitting element mounted on the built-in circuit board is guided to the side surface 2S of the housing by the lens light guide component to emit light. The structure of the display lamp unit 3 will be described as an example. The display device is not limited to a tablet, and may be another type of display device in which a lens light guide component is used for the display lamp unit and a display is provided.

  FIG. 4A shows a first form of the light guide member 20 of the first embodiment of the present application used for the display lamp portion 3 provided on the side surface 2S of the display device 1 shown in FIG. Viewed from the back side. The light guide member 20 can be made by molding a material having translucency, and the completed light guide member 20 has flexibility. An example of such a material is silicon. The light guide member 20 includes a light receiving unit 21 having an incident surface on which light is incident, a light output unit 22 from which light is emitted, a body unit 23 inserted into a through hole provided in the housing, and the light receiving unit 21 and the body. There is a slope 24 provided between the portions 23. Further, a ridge 25 having a semicircular cross section around the body part 23 is provided on the side of the body part 23 close to the light output part 22.

  FIG. 4B shows the second embodiment of the first embodiment of the present application in which the light receiving portion 21 of the light guide member 20 of the first embodiment shown in FIG. The optical member 20A is viewed from the back side. The light guide member 20 </ b> A of the second form is provided with a light receiving part 21, a light output part 22, a body part 23, a slope 24 and a protrusion 25, similar to the light guide member 20 of the first form. The cutout portion 26 is provided in the light receiving portion 21, and this is for avoiding interference with the housing when the body portion 23 of the light guide member 20A is inserted into a through-hole provided in the housing. . Depending on the shape of the housing, only the light guide member 20 of the first form may be required, and the light guide member 20A of the second form may be unnecessary.

  The display lamp unit 3 provided on the side 2S surface of the display device 1 shown in FIG. 1B has three display lamps. Therefore, in the first embodiment, two light guide members 20 of the first form and one light guide member 20A of the second form are used to guide the lens as shown in FIG. A part 30 is formed. 4C shows the lens light guide component 30 viewed from the back side (inside the housing), and FIG. 5A shows the lens light guide component 30 viewed from the front side. (B) shows the lens light guide component 30 as viewed from the side.

  The lens light guide component 30 is an insert for arranging two light guide members 20 of the first form and one light guide member 20A of the second form in a mold and filling the mold with resin. It can be formed by molding. At this time, the three light guide members 20 and 20A are arranged in the mold in correspondence with the positions of the through holes in the housing. As can be seen from FIGS. 4B, 5A, and 5B, the lens light guide component 30 includes two light guide members 20, a light receiving portion 21 of one light guide member 20A, and a slope 24. Although the main body part 31 covered with the resin is provided, the light incident surface of the light receiving part 21 is exposed from the main body part 31. In addition, a slope 34 that is inclined along the slope 24 is formed of resin on the outside of the slope 24. The inclination angle of the slope 24 and the slope 34 may not be the same. The body portion 23 of the light guide member 20 and the light guide member 20A protrudes from the main body portion 31 and is not covered with resin.

  FIG. 6A shows a process of attaching the lens light guide component 30 to the inside of the display lamp portion 3 housing provided on the side surface 2S of the housing 2 of the display device shown in FIG. . The light guide part 30 and the body part 23 of the lens light guide component 30 are inserted into the through hole 2H formed in the side surface 2S and attached to the side surface 2S from the inside. Although the outer diameter of the protrusion 25 provided in the body part 23 is slightly larger than the inner diameter of the through hole 2H formed in the side surface 2S. Since the light guide members 20 and 20A have flexibility, the protrusion 25 enters the through hole 2H in a compressed state. The through hole 2 </ b> H is a leading hole (tapered hole), and its inner diameter is formed smaller as it is closer to the outside of the housing 2.

  In addition, an obliquely inclined rib 2R is provided inside the side surface 2S of the housing 2 of the present embodiment, and the notch portion 26 of the light guide member 20A is provided to avoid interference with the rib 2R. ing. If there is no obliquely inclined rib 2 </ b> R inside the side surface 2 </ b> S of the housing 2, three light guide members 20 can be used for the lens light guide component 30.

  FIG. 6B shows a state where the lens light guide component 30 shown in FIG. 6A is attached to the side surface 2S of the housing 2. Due to the cutout portion 26, the light guide member 20 </ b> A does not interfere with the obliquely inclined rib 2 </ b> R provided inside the side surface 2 </ b> S of the housing 2. Further, the light incident surface of the light receiving unit 21 is exposed inside the housing 2.

  FIG. 7A shows a state in which the lens light guide component 30 shown in FIG. 6B is attached to the side surface 2S of the housing 2 as viewed from the outside of the housing 2. FIG. The casing 2 shown in FIG. That is, in the case 2 shown in FIG. 7A, the upper side of the figure is the side to which a display device to be described later is attached. From the side surface 2S of the housing 2, it can be seen that the light output portions 22 of the light guide members 20 and 20A are exposed. FIG. 7B is a cross-sectional view of the Y portion of FIG. 7A viewed from the same direction as FIG. 6B. From this figure, it can be seen that the protrusion 25 is positioned in the through hole 2H in a compressed state.

  FIG. 8A shows a process of incorporating the display assembly 40 into the housing 2 shown in FIGS. 6B and 7B to which the lens light guide component 30 is attached. The display assembly 40 forms the display unit 4 shown in FIG. 1A and includes a touch panel 41 and a liquid crystal display (LCD) 42. The touch panel 41 is bonded to the liquid crystal display 42 with the double-sided tape 17. Further, the end portion 42 </ b> C on the side facing the lens light guide component 30 of the liquid crystal display 42 is formed in a curved shape so as to smoothly press the slope 34 when contacting the slope 34 of the lens light guide component 30. ing. A double-sided tape 17 is affixed to a portion of the housing 2 where the display assembly 40 is joined.

  When the liquid crystal display 42 is brought close to the housing 2 from the state shown in FIG. 8A, the end portion 42 </ b> C of the liquid crystal display 42 comes into contact with the inclined surface 34 of the lens light guide component 30. At this time, the liquid crystal display 42 is not completely joined to the housing 2 by the double-sided tape 17. When the liquid crystal display 42 is further moved to the housing 2 side from this state and the liquid crystal display 42 is joined to the housing 2 by the double-sided tape 17, the end portion 42 </ b> C of the liquid crystal display 42 becomes the slope 34 of the lens light guide component 30. The lens light guide component 30 is pushed into the through hole 2H.

  FIG. 8B shows a state in which the liquid crystal display 42 shown in FIG. 8A is joined to the housing 2 by the double-sided tape 17. Since the outer diameter of the through hole 2H is smaller than that of the inner side of the housing 2, when the lens light guide component 30 is further pushed into the through hole 2H, the protrusion 25 provided in the body portion 23 is formed. It is further crushed.

  FIG. 9A shows a process of incorporating the circuit board assembly 50 and the back cover 5 from the opposite side of the display assembly 40 into the housing 2 in which the display assembly 40 shown in FIG. Is. The circuit board assembly 50 is provided with a circuit board 9 on which a light emitting element (LED) 10 and a circuit component 11 are mounted, an inner housing 12 having a rubber packing 18 at an edge, a metal part 13, and a heat pipe 16. Yes. The light emitting element 10 is mounted on the circuit board 9 at a position facing the light receiving portion 21 of the lens light guide component 30 incorporated in the housing 2. A light emitting diode (LED) can be used for the light emitting element 10. Further, the rubber packing 18 provided at the edge of the internal housing 12 is provided at a position facing the side surface of the rib 2R of the housing 2.

  FIG. 9B shows a cross section in a state where the lens light guide component 30, the display assembly 40, the circuit board assembly 50, and the back cover 5 are incorporated in the housing 2, and this state is shown in FIG. This corresponds to the cross section of the portion X shown in FIG. Since the protrusion 25 of the lens light guide component 30 is firmly pressure-bonded to the inner peripheral surface of the through hole 2H of the housing 2, water can be prevented from entering the inside of the housing 2 from the through hole 2H. Even if water pressure is applied to the light exiting portion 22 of the lens light guide component 30, the inclined surface 34 of the lens light guide component 30 is pressed by the end portion 42C of the liquid crystal display 42 of the display assembly 40. The optical component 30 does not move into the housing 2 due to water pressure. For this reason, it is not necessary to provide another stopper structure for preventing the lens light guide component 30 from moving due to water pressure inside the housing 2.

  Furthermore, a portion for attaching a double-sided tape for joining the lens light guide component 30 to the housing is unnecessary in the vertical direction of the lens light guide component 30. Since the height of the protrusion 25 provided on the body portion 23 of the lens light guide component 30 can be lowered compared to the case where the lens light guide component is attached to the housing with a waterproof double-sided tape like the lens light guide component of the comparative technique. The height of the lens light guide component 30 can be reduced. As a result, the thickness of the display device 1 using the lens light guide component 30 can be reduced.

  Here, the lens light guide component 30 will be described with reference to FIGS. 4 and 7 together. The light emitting element 10 emits light in response to detection of a predetermined state transition by the circuit board 9 such as an ON state of a power source, a charging required state where the remaining battery level is below a threshold, or a waterproof level state. The light emitted from the light emitting element 10 enters from the light receiving unit 21 disposed facing the light emitting element 10 and is guided to the body unit 23 and the light emitting unit 22. At this time, the main body 31 is located between the light guide members 20 and obstructs the transmission of light on the surface facing the light receiving part different from the light receiving part 21 that has entered the light. Specifically, the lens light guide component 30 guides light incident from the light receiving unit 21 to the light guide member 20. Then, the lens light guide component 30 guides the light transmitted through the light guide member 20 to the light output unit 22. At this time, the main body 31 suppresses light leakage to the light guide member 20 or the light exiting part 22 adjacent to the light guide member 20 corresponding to the light emitting element 10 or the light exiting part 22 corresponding to the light emitting element 10. Thereby, even when the arrangement interval of the light emitting parts 22 is short due to the downsizing and thinning of the housing 2, the lens light guide component 30 allows the light emitted from the light emitting elements 10 to correspond to the light emitting elements 10. 22 only.

  The inclined surface 34 of the lens light guide component 30 is pressed by the end portion 42 </ b> C of the liquid crystal display 42 of the display assembly 40, but the target to be pressed is not limited to the liquid crystal display 42. That is, the liquid crystal display 42 is an example of a “unit”, and the “unit” is partially fixed to the housing 2 in a state of being housed in the housing 2, and a part of the “unit” is lens-guided. What is necessary is just to press the slope 34 of the optical component 30. FIG. A battery unit, a fan unit, an optical disk drive (ODD: Optical Disk Drive) unit, a hard disk drive (HDD: Hard Disk Drive) unit, and the like correspond to examples of the “unit”. The “unit” is sandwiched from both sides in the lateral direction by the rib 2R extending from the inside of the side surface 2S of the housing 2 or the side surface 2S of the housing 2. Thereby, the movement of the “unit” in the side surface direction can be suppressed.

  In the lens light guide component 30 of the embodiment described above, one protrusion 25 is provided on the body part 23, but the number of protrusions 25 provided on the body part 23 is not particularly limited. FIG. 10 shows a lens light guide component 30A, which is a modification of the lens light guide component 30 of the first embodiment shown in FIG. 5A, as viewed from the front side. The body portion 23 is provided with two ridges 25.

  FIG. 11 shows a state in which the lens light guide component 30B of the second embodiment of the present application is attached to the X portion of the display device 1 shown in FIG. 1B, and FIG. Corresponds to the cross section shown in FIG. The constituent members other than the lens light guide component 30B of the display device 1 may be the same as the constituent members of the display device 1 shown in FIG. 9B. Omitted.

  The lens light guide component 30B of the second embodiment is different from the lens light guide component 30 of the first embodiment in that the angle of the inclined surface 24 provided on the light guide members 20 and 20A is determined by the axis of the body portion 23 or light reception. This is a point formed at 45 degrees with respect to the light incident surface of the portion 21. Then, the overlap between the inclined surface 24 provided on the light guide members 20 and 20A and the light incident surface of the light receiving portion 21 of the light guide members 20 and 20A is made larger than that of the lens light guide component 30 of the first embodiment. ing.

  Another difference is that a mirror 27 is built in between the slope 34 of the lens light guide component 30B and the slope 24 of the light guide members 20 and 20A. When the mirror 27 is incorporated between the slope 34 of the lens light guide component 30B and the slope 24 of the light guide members 20 and 20A, insert molding is performed with the mirror 27 attached to the slope 24 of the light guide members 20 and 20A. Just do it. Further, instead of incorporating the mirror 27, the mirror surface may be formed by vapor deposition on the inclined surfaces 24 of the light guide members 20 and 20A.

  In this way, the angle of the inclined surface 24 is formed to be 45 degrees with respect to the light incident surface of the light receiving portion 21 to incorporate the mirror 27, and overlap with the light incident surface of the light receiving portion 21 of the light guide members 20, 20A. Is increased, the light incident from the LED 10 is reflected by the mirror 27 and emitted from the light output part 22 as indicated by a broken line. For this reason, compared with the case where the light incident from the LED 10 is repeatedly reflected in the light guide member and is emitted from the light exit part 22, the intensity of the light emitted from the light exit part 22 can be increased, and the lamp is lit brightly. be able to.

  The above embodiments can be implemented in combination with each other without departing from the object. Furthermore, it is needless to say that the present application is not limited to the above-described embodiments, and includes other modifications and application examples without departing from the gist of the invention described in the claims.
