Description

  The present invention relates to a sensing electronic device having a housing and an antenna disposed in the housing.

  2. Description of the Related Art A GPS portable device that obtains user position information using a global positioning system (GPS) is known. The GPS portable device is carried by the user when used. Some GPS portable devices measure a user's movement distance, detect a movement route, and the like based on acquired position information.

  The GPS portable device has, as its configuration, a housing, an antenna that receives radio waves emitted from an artificial satellite, a substrate and electronic components that perform functions such as storing position information, and a driving battery. The antenna, the substrate, the electronic component, and the battery are accommodated in the housing.

  It is known that the reception function of an antenna is generally lowered due to the influence of the ground of the substrate. The ground is disposed in a portion other than the wiring in the substrate and is formed of a metal material. For this reason, a technique is known in which the antenna is formed in an upright shape with respect to the substrate and is electrically connected to the substrate to prevent the function from being deteriorated. By forming the antenna in this way, the antenna is disposed at a position away from the substrate, and the function of the antenna is prevented from deteriorating (see, for example, Patent Documents 1 and 2).

  The use of the above-described antenna formed in a standing shape with respect to the substrate for a sensing electronic device carried by a user such as a GPS portable device has the following problems. That is, the sensing electronic device carried by the user is required to be miniaturized so that the user can easily carry it. Since the GPS portable device is often used when a user performs an exercise such as a marathon, a downsizing is particularly required. However, by forming the antenna upright with respect to the substrate, it is necessary to secure a large space for arranging the antenna in the casing, and the casing is increased in size.

  In view of the above, an object of the present invention is to provide a sensing electronic device that can prevent an increase in the size of a housing while preventing a decrease in the function of an antenna.

  As one embodiment of the present invention, a sensing electronic device includes a housing, a substrate disposed in the housing, on which an electronic component is mounted, and a planar antenna including a longitudinal side and a lateral side. And an antenna disposed on the edge side of the substrate in a posture in which the longitudinal direction is along the inner surface of the housing and the surface of the antenna faces the inner surface of the housing.

  As shown in FIG. 1, the housing 20 is formed in a flat shape, for example. As shown in FIG. 3, the housing 20 is composed of, for example, a plurality of components. Specifically, the casing 20 is fixed to, for example, a bowl-shaped casing main body 21 that opens at one side, and constitutes one part in the thickness direction, and the opening of the casing main body 21 is sealed. The lid member 22 is formed so as to be capable of being formed. FIG. 1 shows the GPS portable device 10 in a state where the lid member 22 is fixed to the housing body 21. FIG. 2 shows the GPS portable device 10 with the lid member 22 removed.

  The housing body 21 includes a first end wall portion 23 and a first peripheral wall portion 24 that rises gently from the periphery of the first end wall portion 23. The first end wall portion 23 is formed in a shape that is long in one direction and has a short surface in a direction orthogonal to the one direction. This is because the substrate 31 is formed in a rectangular shape, and the substrate 31 can be disposed inside. Further, as shown in FIG. 3, a housing space forming member 25 that forms a first housing space R <b> 1 is fixed between the housing body 21 and the lid member 22.

It is fixed to. As shown in FIG. 1, the housing 20 is formed with an opening 20 a that can expose the connector 40 to the outside. Further, the housing 20 is formed with holes, slits, and the like for efficiently emitting the sound emitted from the speaker 50 to the outside of the housing 20.

  As shown in FIG. 3, the board unit 30 includes a board 31 and an electronic component 32 mounted on the board 31. The substrate 31 is formed in a rectangular shape. FIG. 3 shows a state where the GPS portable device 10 is cut along a cross section orthogonal to the longitudinal direction of the substrate 31. The substrate 31 has wiring on its main surface 33. In addition, the substrate 31 is provided with a ground for releasing electricity at a portion where wiring is not applied.

  The electronic component 32 is mounted on the main surface 33 of the substrate 31 and is electrically connected to the wiring. The electronic component 32 is, for example, an electronic component having a function of detecting the position information of the GPS portable device 10 based on the radio wave received by the antenna 100, a memory that stores the detected position information, and the like. The electronic component is not limited to these. As the electronic component, an electronic component necessary for achieving the function required for the GPS portable device 10 is used.

  The substrate unit 30 configured as described above is disposed in the first accommodation space R1 in a posture in which the main surface 33 of the substrate 31 faces the second end wall portion 26 of the housing body 21. Further, the substrate 31 has a posture in which the edge along the longitudinal direction is opposed to the portion along the longitudinal direction of the housing 20 in the second peripheral wall portion 27, and the edge along the short direction of the substrate 31 is the first The second peripheral wall portion 27 is disposed in the first accommodating space R <b> 1 so as to face the portion along the short direction of the housing 20.

  As shown in FIGS. 1 and 2, a part of the connector 40 is disposed, for example, in the first accommodation space R <b> 1 inside the housing 20. Specifically, the connector 40 is disposed at a position facing the edge along the short direction of the substrate 31 among the edges of the substrate 31. The connector 40 is, for example, a USB connector. The connector 40 is electrically connected to the substrate 31. A portion of the connector 40 to which the USB is connected is exposed to the outside of the housing 20 through the opening 20a, and the USB can be connected from the outside.

  The speaker 50 is disposed, for example, in the first housing space R1 inside the housing 20. Specifically, the speaker 50 is disposed at a position opposite to the edge along the short side direction of the edge of the substrate 31 and on the opposite side of the connector 40. The speaker 50 is electrically connected to the substrate 31. The speaker 50 is configured to be able to issue an alarm that alerts the surroundings, for example, when it is detected that the GPS portable device 10 is above a specific altitude based on the acquired position information.

  The operation unit 60 is disposed on the surface of the housing 20 as shown in FIG. Specifically, the operation unit 60 is disposed on the surface of the peripheral wall portion, which is a portion facing the edge along the longitudinal direction of the substrate 31 in the housing 20. The operation unit 60 is formed to be operable by the user. The operation unit 60 is electrically connected to the substrate 31. The operation unit 60 includes a power button, a switch that enables the GPS portable device 10 to be connected to an external device wirelessly, and the like. The operation unit 60 is not limited to the one described above. The operation unit 60 is configured according to functions and the like that the GPS portable device 10 has.

  As shown in FIG. 3, the battery case 70 is fixed on the other main surface 34 of the substrate 31, and is formed so that the battery 80 can be accommodated therein. Note that FIG. 3 and FIG. 4 used later show a state in which a part of the housing 20 is cut out, but the substrate 31 is not cut. The battery case 70 has, for example, a hook-shaped engagement portion 75. The substrate 31 is formed with a hole in which the engaging portion 75 is engaged. The battery case 70 is fixed to the substrate 31 by engaging the engaging portion 75 with the hole of the substrate 31.

  The battery case 70 is made of a resin material. Specifically, the battery case 70 includes a main body portion 71 formed in a bowl shape that opens toward the main surface 34, and an antenna fixing portion 72 formed in the main body portion 71. The main body 71 forms a second accommodating space R <b> 2 between the main surface 34 of the substrate 31. The second accommodation space R2 has a size that can accommodate the battery 80.

  The main body 71 is arranged at a position close to one side in the short direction of the substrate 31. In other words, the main body 71 is disposed on one edge side along the longitudinal direction of the substrate 31 on the main surface 34 of the substrate. More specifically, the main body 71 is disposed in the vicinity of the edge along the longitudinal direction of the substrate 31. Therefore, a space S is provided between the main body 71 and one of the other edges along the longitudinal direction of the substrate 31. This is because the substrate 31 is larger than the main body 71. The substrate 31 has a relatively large area for mounting a plurality of electronic components 32. Furthermore, as the GPS portable device 10 has more functions, the number of electronic components 32 to be mounted increases, and thus the substrate 31 tends to increase. Therefore, a space S is provided on the substrate 31 around the main body 71 of the battery case 70. By disposing the main body 71 on one edge side of the substrate 31 on the main surface 34 of the substrate 31, the battery 80 is also disposed on this edge side. In other words, the battery case 70 is arranged as described above in order to arrange the battery 80 on the edge side of the substrate in the main surface 34 of the substrate 31.

  The antenna fixing portion 72 is disposed in the space S. The antenna fixing portion 72 extends to the other edge along the longitudinal direction of the substrate 31, that is, to the vicinity of the edge opposite to the edge side where the battery 80 is disposed. Further, the height of the antenna fixing portion 72 in the direction orthogonal to the main surface 34 of the substrate 31 is less than the height of the main body portion 71 with respect to the main surface 34. In the present embodiment, the height of the antenna fixing portion 72 with respect to the main surface 34 is set to, for example, approximately half the height of the main body portion 71 with respect to the main surface 34. The battery 80 is disposed in a second accommodation space R <b> 2 formed between the main body 71 and the main surface 34.

  The antenna fixing part 72 has a fixing surface 73 to which the antenna 100 is fixed. The fixing surface 73 is a surface facing the inner surface 29 a of the peripheral wall portion 29 of the lid member 22 in the antenna fixing portion 72. By fixing the antenna 100 to the fixing surface 73, the antenna 100 is disposed between the inner surface 29 a and the battery 80. In other words, the antenna 100 has an inner surface 29a whose longitudinal direction is the opposite side of the surface (second surface) 20d different from the surface 23a of the first end wall 23 which is a part of the surface of the housing 20. And the main surface 104 which is the surface of the antenna 100 is disposed on the edge side of the substrate 31 in a posture facing the inner surface 29a of the housing 20. The fixed surface 73 is formed so that the antenna 100 fixed to the fixed surface 73 is in a posture in which the longitudinal direction of the antenna 100 is along the inner surface of the housing 20.

  In the present embodiment, the fixing surface 73 faces the inner surface 29 a of the peripheral wall portion 29 of the lid member 22. The fixed surface 73 is formed on a surface parallel to the inner surface 29a so that the antenna 100 fixed to the fixed surface 73 is in a posture parallel to the inner surface 29a which is an example of a posture along the inner surface 29a. In the present embodiment, the inner surface 29 a is formed on a plane orthogonal to the plane including the main surface 34 of the substrate 31. For this reason, the fixed surface 73 is formed in a plane orthogonal to the main surface 34. In the present embodiment, the fixing surface 73a is disposed on the edge 31a along the longitudinal direction of the substrate 31 on the main surface 34, as shown in FIG.

  As shown in FIGS. 1 and 2, the LED 90 is mounted on a flexible substrate 91 that is electrically connected to the substrate 31, for example. The integrated body of the flexible substrate 91 and the LED 90 is disposed on the surface of the main body 71 of the battery case 70. In addition, the surface said here is a surface in the main-body part 71 facing the end wall part 28 of the cover member 22. As shown in FIG. The portion of the lid member 22 that faces the LED 90 is formed of, for example, a transparent material so that the light emitted from the LED 90 can be emitted to the outside of the housing 20. Alternatively, the lid member 22 may be formed of a totally transparent material. The LED 90 lighting pattern notifies the user of various information related to the GPS portable device, such as the remaining battery level.

  The antenna 100 is formed so as to be able to receive an electromagnetic wave emitted from an artificial satellite used for GPS. Specifically, the antenna 100 includes a flexible substrate 101 and an antenna line 102 fixed to the flexible substrate 101 as shown in FIG.

  The flexible substrate 101 is formed in a rectangular shape that is long in one direction. This is because the antenna wire 102 is formed in a shape that is long in one direction, and this antenna wire 102 is supported. That is, the antenna 100 is formed by fixing an antenna wire 102 to a flexible substrate 101 having a planar shape composed of a side in the longitudinal direction and a side in the lateral direction. As described above, the flexible substrate 101 has a rectangular shape, that is, the antenna 100 is formed in a planar shape including the longitudinal side and the lateral side by having the lateral side 101a and the lateral side 101b. Will be. In the antenna 100, one main surface 103 of the flexible substrate 101 is fixed to the fixing surface 73 of the antenna fixing portion 72 with the longitudinal direction of the flexible substrate 101 being along the inner surface 29 a of the housing 20. That is, the antenna 100 is positioned in such a posture that the longitudinal direction of the flexible substrate 101 is along the inner surface 29 a of the housing 20 and the surface of the flexible substrate 101 is opposed to the inner surface 29 a of the housing 20.

  The fixed surface 73 is formed in a parallel plane on the inner surface 29 a of the housing 20, that is, the inner surface that is a portion facing the antenna 100 in the housing 20. Therefore, the antenna 100 is disposed between the inner surface 29a and the battery 80 in a posture in which the other main surface 104 is parallel, which is an example of a posture along the inner surface 29a.

  The antenna wire 102 is fixed to the other main surface 104 of the flexible substrate 101 so that the longitudinal direction of the antenna wire 102 is along the longitudinal direction of the flexible substrate 101. For this reason, the antenna wire 102 is arranged in the housing 20 in a posture in which the longitudinal direction thereof is along the inner surface 27 a of the housing 20. The antenna line 102 is disposed at a position relatively distant from the main surface 34 of the substrate 31 on the main surface 104. In the present embodiment, the antenna line 102 is disposed on the main surface 104 at a portion higher than the antenna fixing portion 72 with respect to the main surface 34 of the substrate 31. The antenna wire 102 is disposed at a position closer to the end wall portion 28 of the lid member 22 than the substrate 31. That is, the antenna wire 102 is disposed between the inner surface and the substrate 31 in a posture along the inner surface of the end wall portion 28. The antenna line 102 is electrically connected to the substrate 31.

  The antenna 100 configured as described above is disposed in the housing 20 between the inner surface 29a of the housing 20 and components other than the antenna 100 disposed in the housing 20, and The longitudinal direction is arranged in a posture along the inner surface 29a. Specifically, in the antenna 100, the antenna wire 102 is disposed between the battery 80 and the inner surface 29a so that the longitudinal direction of the antenna wire 102 is along the inner surface 29a. Further, in the antenna 100, the antenna wire 102 is disposed between the inner surface of the end wall portion 28 of the lid member 22 and the substrate 31 with the longitudinal direction of the antenna wire 102 being along the inner surface of the end wall portion 28. It becomes. In the present embodiment, the antenna 100 is disposed in a posture parallel to the inner surface 29a, but is not limited to being parallel.

  The attitude along the inner surface 29a referred to here is an attitude that can be arranged in a gap between the constituent elements other than the antenna 100 arranged in the housing 20 and the inner surface 29a. And it is the attitude | position which can be arrange | positioned in the position away from the board | substrate 31 or the battery 80. FIG. The distant position referred to here is a position where the function of the antenna 100 is sufficiently maintained. When the gap between the inner surface of the housing and other components is reduced, the antenna 100 is brought closer to the inner surface of the housing 20 by making the posture of the antenna 100 parallel or substantially parallel to the inner surface of the housing. Can be arranged. That is, the antenna 100 can be arranged away from the substrate 31 and the battery 80. For this reason, it is possible to prevent the function of the antenna 100 from being deteriorated.

  In the GPS portable device 10 configured as described above, the antenna 100 is disposed between the inner surface 29 a and the antenna fixing portion 72 of the battery case 70 with the longitudinal direction thereof being along the inner surface 29 a of the housing 20. For this reason, since the antenna 100 can be disposed at a position close to the inner surface 27a, the antenna 100 can be disposed away from the substrate 31 and the battery 80. Therefore, it is possible to prevent the function of the antenna 100 from being deteriorated. Moreover, the antenna 100 can be arrange | positioned in the existing clearance gap between the inner surface 27a and the battery case 70 by arrange | positioning with the attitude | position in which the longitudinal direction follows the inner surface 27a. That is, it is not necessary to newly form a space for arranging the antenna 100 in the housing 20. For this reason, the enlargement of the housing | casing 20 can be prevented.

  As described above, the GPS portable device 10 according to the present embodiment can prevent the casing 20 from being enlarged while preventing the function of the antenna 100 from being deteriorated.

  Further, by fixing the antenna 100 to the antenna fixing portion 72 of the battery case 70, the substrate unit 30, the connector 40, the speaker 50, the battery case 70, the battery 80, the LED 90, and the antenna 100 are configured as one unit. be able to. For this reason, when manufacturing the GPS portable device 10, it is only necessary to arrange this unit in the housing body 21 of the housing 20 and then fix the lid member 22 to the housing body 21. Since the GPS portable device 10 can be manufactured in this way, the manufacturing efficiency of the GPS portable device 10 can be improved.

  Further, by forming an antenna fixing portion 72 that protrudes away from the battery 80 in the battery case 70 that houses the small battery 80 with respect to the substrate 31, the substrate unit 30, the connector 40, the speaker 50, the battery case 70, The antenna 100 can be arranged at a position away from the battery 80 without increasing the size of the unit including the battery 80, the LED 90, and the antenna 100. For this reason, it is possible to prevent the GPS portable device 10 from being enlarged while preventing the function of the antenna 100 from being lowered. Furthermore, by disposing the antenna line 102 in a portion of the flexible substrate 101 that is away from the substrate 31, it is possible to prevent the function of the antenna 100 from being deteriorated.

  Further, by arranging the antenna 100 in a posture along the peripheral wall portion arranged around the thickness direction of the flat casing 20, that is, the inner surface 29 a which is the inner surface of the peripheral wall portion continuous to the end wall portion, the antenna 100 is provided. The function of 100 can be prevented from deteriorating. This point will be specifically described.

  The casing 20 of the GPS portable device 10 is formed in a flat shape, so that the width along the short direction of the first end wall 23 of the casing body 21 and the short of the end wall 28 of the lid member 22 are formed. The width (length along the thickness direction of the casing 20) of the peripheral wall portion constituted by the first peripheral wall portion 24 and the peripheral wall portion 29 is smaller than the width along the hand direction. For this reason, the GPS portable apparatus 10 is stably fixed to the user by bringing the first end wall portion 23 or the end wall portion 28 into contact with the user's body.

  For this reason, when the user wears the GPS portable device 10, the GPS portable device 10 is placed on the user's body with the outer surface of the first end wall portion 23 or the outer surface of the end wall portion 28 in contact with the body. To become fixed. In the present embodiment, the GPS portable device 10 recommends that the surface on which the LED 90 can be viewed be fixed to the body away from the body. The user confirms the LED 90, and in a state where the surface 23a (first surface) of the first end wall portion 23 of the housing body 21 which is the surface opposite to the LED 90 is in contact with the body, That is, the GPS portable device 10 can be fixed to the body so that the surface 23a comes into contact with the user. That is, the LED 90 is an example of a mark referred to in the present invention. Further, when the GPS portable device 10 is fixed to the body as described above, the hole portion where the sound from the speaker 50 is emitted, the connector 40, and the operation portion 60 are arranged at the location of the GPS portable device that is not covered by the user's body. Will be.

  When the GPS portable device 10 is fixed to the user with the first end wall portion 23 in contact with the user, the peripheral wall portion facing the antenna 100 is not covered by the user's body. For this reason, it is prevented that the function of the antenna 100 falls.

  In the present embodiment, the antenna 100 includes the flexible substrate 101 and the antenna line 102 as its configuration, but is not limited thereto. As another example, a configuration having only the antenna line 102 may be used. Also in this case, the antenna wire 102 can be disposed close to the inner surface of the housing 20 by arranging the antenna wire 102 in a posture in which the longitudinal direction thereof is along the inner surface of the housing 20. The effect is obtained. Further, in the configuration having the antenna line 102, when the antenna line 102 is folded, for example, and has a plurality of line parts arranged in a direction orthogonal to the longitudinal direction, the longitudinal direction side where these line parts are arranged and A virtual plane composed of sides in the short direction can be assumed. That is, even in a configuration having only the antenna line 102 without the flexible substrate 101, it can be considered as a planar antenna having this virtual plane. Thus, even the antenna 100 having a virtual plane is arranged on the edge side of the substrate 31 with the longitudinal direction thereof along the inner surface of the housing 20 and the surface of the antenna 100 facing the inner surface of the housing 20. As a result, the same effects as in the present embodiment can be obtained. Further, in this embodiment, the antenna 100 does not have the flexible substrate 101, and the antenna line 102 has a plurality of line portions arranged side by side in a direction orthogonal to the longitudinal direction of the antenna line 102. Even in the case where there is no structure, the same effect can be obtained by fixing the longitudinal direction of the antenna 100 to the fixing surface 73 of the antenna fixing portion 72 in a posture along the inner surface 29a of the housing 20.

  In the present embodiment, the antenna 100 is disposed between the inner surface 29a and the battery case 70 in a posture along the inner surface 29a of the peripheral wall portion 29 of the lid member 22 of the housing 20, but is not limited thereto. The antenna 100 may be disposed between the arbitrary portion and other components in a posture along an arbitrary portion of the inner surface of the housing 20. For example, the antenna 100 has a longitudinal direction along the inner surface 26 a of the second end wall portion 26 of the housing space forming member 25 of the housing body 21, and the inner surface 26 a of the second end wall portion 26 and the substrate 31. You may arrange | position between.

  Even in this case, the antenna 100 is arranged in a posture in which the longitudinal direction thereof is along the inner surface 26 a of the second end wall portion 26, so that the gap between the inner surface 26 a of the second end wall portion 26 and the substrate 31 is increased. In FIG. 3, the substrate can be arranged at a position away from the substrate 31. Further, the antenna 100 can be disposed in the existing gap between the inner surface 26 a and the substrate 31. Therefore, it is possible to prevent the GPS portable device 10 from becoming large while preventing the function of the antenna 100 from deteriorating.

  As described above, the antenna 100 is arranged between the portion and other components in a posture along the portion regardless of the length of the inner surface of the housing 20. Since it is arranged using the existing gap between that part of the inner surface and other configurations, and is arranged at a position away from the substrate 31 and the battery 80, the function of the antenna 100 is prevented from being deteriorated. On the other hand, an increase in the size of the GPS portable device 10 can be prevented.

  Furthermore, in this embodiment, the antenna fixing portion 72 is formed integrally with the battery case 70, but is not limited to this. The antenna fixing portion 72 may be separate from the battery case 70. FIG. 4 is a cross-sectional view showing this modification. 4 shows a state where the GPS portable device 10 is cut along a cross section orthogonal to the longitudinal direction of the antenna 100, as in FIG. In the modification shown in FIG. 4, the antenna fixing portion 72 is configured separately from the battery case 70, and is disposed in one space along the longitudinal direction of the substrate 31 and in the space S between the battery cases 70. It is fixed to the substrate 31. As described above, the antenna fixing portion 72 can be arranged by using the space S between the edge of the substrate 31 and the battery case 70 which are increased in size with an increase in functionality.

  Moreover, in this embodiment, although the antenna 100 is being fixed to the unit comprised from the board | substrate unit 30, the battery case 70, the battery 80, etc., it is not limited to this. In another example, the antenna 100 may be fixed to the inner surface of the housing 20 in a posture along the longitudinal direction of the antenna 100 along the inner surface. That is, the antenna 100 is not a unit composed of the substrate unit 30, the battery case 70, the battery 80, and the like as long as the distance from the object that adversely affects the function of the antenna 100 can be taken. The longitudinal direction of the antenna 100 may be fixed to the inner surface of the housing 20 in a posture along the inner surface. Even in this case, the antenna 100 is arranged such that the longitudinal direction thereof is along the inner surface of the housing 20 and between the inner surface and another configuration.

In another example, the antenna 100 may be disposed between the inner surface 29a and the edge 31a along the longitudinal direction of the substrate 31. For example, the fixing surface 73a of the antenna fixing portion 72 is disposed on the edge 31a along the longitudinal direction of the substrate 31, whereby the substrate 31 can be disposed between the inner surface 29a and the edge 31a.

  Even if the antenna 100 is arranged in this way, the antenna 100 is arranged on the edge side of the substrate 31. By arranging the antenna 100 in this manner, the antenna 100 has a longitudinal direction along the inner surface 29a of the housing 20, and the main surface 104 which is the surface of the antenna 100 faces the inner surface 29a so that the substrate 31 faces. It is arranged between the substrate 31 and the inner surface 29a of the housing 20 on the edge side. Even if the antenna 100 is arranged in this manner, the antenna 100 is arranged between the inner surface 29 a and the battery 80.
