Description

  The present invention relates to a portable terminal, for example, a battery cover of a mobile printer.

  In recent years, there is a user's desire to use a portable terminal such as a mobile phone or a mobile printer for a longer period of time or to support use in a special environment. In order to respond to such a demand, for example, as in Patent Document 1, a large-capacity battery (hereinafter referred to as a special battery) is attached instead of a battery normally provided in a mobile terminal (hereinafter referred to as a normal battery for convenience). Configuration is considered.

JP 5-3101414 A

  The mobile terminal disclosed in Patent Document 1 is a mobile phone, and a battery is attached by inserting a normal battery or a special battery into a notch formed in the mobile terminal body. A part of the outer shell of these batteries also serves as the outer shell of the mobile terminal itself.

  On the other hand, a portable terminal having a battery mounting structure of a type different from that of Patent Document 1, for example, a mobile printer as shown in FIG. 1, is configured such that a normal battery is completely stored in a battery chamber inside the printer. . The battery chamber is closed by a battery lid shaped to fit the opening of the battery chamber. Therefore, the normal battery stored in the battery chamber to which the battery cover is attached is held so as not to jump out and is appropriately protected against an external load.

  As shown in FIG. 1, the mobile printer has a size in the width direction (X direction in the figure) larger than the dimension in the height direction (Z direction in the figure) and depth direction (Y direction in the figure). It has a rectangular parallelepiped shape. In this mobile printer 100, a rod-shaped normal battery 310 is used so that the capacity of the normal battery 310 is as large as possible within a range that does not increase the size of the printer itself. That is, a battery chamber 110 that is long in the width direction is formed at the rear portion of the mobile printer 100, and the normal battery 310 is stored such that the longitudinal direction thereof is the width direction of the battery chamber (FIG. 1A).

  In such a mobile printer 100, when a special battery is used, the special battery 330 is larger than the normal battery 310 and has a cross-sectional shape different from that of the normal battery in a plane orthogonal to the longitudinal direction ( FIG. 1 (B)). When the special battery 330 is used, the special battery 330 does not fit in the battery chamber 110 and a part of the special battery 330 protrudes from the terminal body. Therefore, the battery lid that is normally used when using the battery cannot be used as it is. When the special battery is used, a dedicated battery lid is required to appropriately hold and protect the special battery protruding from the battery chamber 110. That is, in the conventional portable small terminal, a different battery lid must be prepared according to the battery to be used, resulting in an increase in the number of parts.

  In addition, since the special battery protrudes from the battery chamber, it is more susceptible to external impact than a normal battery that is always in a stored state during use. Therefore, the battery cover dedicated to the special battery has to have a special and expensive structure with impact resistance so that the special battery can be protected more firmly.

  In view of the above circumstances, the present invention is a portable terminal battery that appropriately holds both a normal battery and a special battery while suppressing the number of parts of the entire terminal, and has a high impact resistance particularly when the special battery is used. An object is to provide a lid and a cover for a portable terminal including the battery lid.

  In order to solve the above problems, the battery lid for a portable terminal according to the present invention is a portable battery that can use a normal battery and a special battery having a cross-sectional shape different from that of the normal battery in a plane orthogonal to the longitudinal direction of the battery chamber. A battery lid for a terminal, having elasticity and configured to be detachable from a portable terminal, and in a state of being attached to the terminal, substantially contacts an opening forming surface of a battery chamber in the terminal, and the opening A first region that closes the battery, a second region that is formed in the first region and that has a recess that stores a partial region protruding from the opening of the special battery stored in the battery chamber, and the battery chamber when the battery is normally used And an entry restricting means for restricting entry of the normal battery stored in the battery into the second area.

  In addition, according to the battery lid for a portable terminal according to claim 2, the entry restricting means is formed in the vicinity of the opening of the second region, and the rib that restricts the movement of the normal battery in the direction toward the second region. It can be configured to have.

  Specifically, according to the battery lid for a portable terminal according to claim 3, the rib protrudes along the depth direction of the battery chamber in a state where the battery lid is attached to the terminal, and is normally stored in the battery chamber. It is desirable to energize the battery.

  Furthermore, according to the battery lid for a portable terminal according to claim 4, the rib is protruded in the direction of narrowing the opening of the second area, and the battery lid is attached to the terminal, and is normally stored in the battery chamber. You may comprise so that it may function as a stopper, when a battery moves to the direction which goes to a 2nd area | region.

  According to the battery lid for a portable terminal according to claim 5, when the special battery has a shape having an apex portion that appears as a shape obtained by adding a triangular region to the cross-sectional shape of the normal battery. The recess of the second region preferably has a V-shaped cross section so that the apex portion of the special battery fits. When configured in this way, the entry restricting means can use the pair of slopes forming the V-shaped recess as the entry restricting means (claim 6).

  According to the battery lid for a portable terminal according to claim 7, it is desirable that the first region has a surface shape that matches the opening forming surface. Thereby, the contact state with the opening forming surface is ensured, and the risk of the battery lid being inadvertently displaced with respect to the terminal is effectively reduced.

  From another viewpoint, the mobile terminal cover according to claim 8 is integrally formed with a battery cover region corresponding to the mobile terminal battery cover having the above characteristics and a covering region covering at least each end of the mobile terminal. Even if either a normal battery or a special battery is used, the battery used is held and protected by the battery lid area, and at the same time, the portable terminal is protected by the protection area.

  As described above, according to the battery lid for a portable terminal according to the present invention, while providing a region in which a part of the special battery protruding from the battery chamber is securely stored, the normal battery is placed in the region when the normal battery is used. Means to limit entry. Thereby, when using a normal battery, the battery can be properly stored in the battery chamber, and when using a large battery such as a special battery, it can be reliably held and protected including the protruding portion of the battery. . That is, according to the present invention, a common battery lid is provided for all batteries. Therefore, the user need not always have a plurality of types of battery lids corresponding to each battery as in the conventional case, and convenience is improved.

  Furthermore, according to the portable terminal cover according to the present invention, in addition to the function as a battery cover common to the different types of batteries as described above, the portable terminal cover also has a function of appropriately protecting the entire portable terminal from an external load. A cover is provided.

  A portable terminal cover according to an embodiment of the present invention will be described with reference to the drawings. First, prior to describing the portable terminal cover of the present embodiment, an outline of the mobile printer 100 as an example of a portable terminal to which the cover can be suitably attached will be described. FIG. 1 is a perspective view clearly showing a portable terminal that can use the portable terminal cover of the present embodiment, more specifically, the back surface 130 of the mobile printer 100. Specifically, FIG. 1A is a perspective view showing the mobile printer 100 when the normal battery 310 is attached, and FIG. 1B shows the mobile printer 100 when the large-capacity battery 330 that is a special battery is attached. It is a perspective view. 2A shows the external appearance of the normal battery 310, and FIG. 2B shows the external appearance of the large-capacity battery 330.

  A mobile printer 100 shown in FIGS. 1A and 1B is provided with a battery chamber 110 having an opening 110 a on the back surface 130. In the following text, for convenience of explanation, the mobile printer 100 is assumed to be in a normal use state in which the bottom surface is placed on a horizontal surface. Then, the X, Y, and Z directions are defined in the mobile printer 100 in the normal use state. Specifically, the width direction of the mobile printer 100, that is, the width direction of the printing medium (for example, printing paper) is defined as the X direction. Further, the depth direction of the mobile printer 100 is defined as the Y direction. Further, a direction orthogonal to the X and Y directions, that is, a height direction (vertical direction) of the mobile printer 100 is defined as a Z direction.

  The normal battery 310 is assumed to be an assembled battery in which two round-bar batteries arranged side by side are fixed by a heat-shrinkable tube or the like. Therefore, as shown in FIG. 2A, the normal battery 310 has an elliptical cross section S1 on a plane (YZ plane) orthogonal to the longitudinal direction (X direction). The large-capacity battery 330 is assumed to be an assembled battery in which three round bar-shaped batteries stacked in a triangular shape are fixed by a heat-shrinkable tube or the like. Therefore, as shown in FIG. 2 (B), the large-capacity battery B2 has a cross-sectional shape in the YZ plane, which corresponds to the cross-sectional area S1a corresponding to the cross-section S1 of the normal battery 310 and the third battery arrangement position. It has a shape obtained by joining the corresponding triangular cross-sectional area S2. Hereinafter, a portion corresponding to the cross-sectional area S1a of the large-capacity battery 330 is referred to as a base portion 331. Further, a portion corresponding to the cross-sectional area S2 of the large-capacity battery 330, that is, a portion where the third battery is disposed is referred to as a protruding portion, in particular, the apex angle portion 332 in the present embodiment.

  As shown in FIG. 1A, the battery chamber 110 of the mobile printer 100 has a shape such that the normal battery 310 can be properly accommodated. Therefore, as shown in FIG. 2B, when the large-capacity battery 330 is mounted, the base portion 331 is accommodated but the apex angle portion 332 cannot be accommodated in the battery chamber 110 and protrudes to the outside. Therefore, the conventional battery lid fitted into the opening 110 a when using the normal battery 310 cannot cope with the use of the large capacity battery 330. In addition, since the battery cover dedicated to the large capacity battery 330 needs to have a special shape corresponding to the protruding portion described above, it is inconvenient to store and carry. In addition, a battery lid dedicated to a large-capacity battery must be combined with a normal battery lid, which causes a problem of increasing the number of parts.

  FIG. 3 is a perspective view showing the mobile terminal cover 10 of the present embodiment configured to appropriately solve the above problem. FIG. 4 is a top view showing the mobile terminal cover 10 of the present embodiment. FIG. 5 is a cross-sectional view taken along line AA of the portable terminal cover 10 shown in FIG. FIG. 6 is a front view of the mobile terminal cover 10 of the present embodiment. FIG. 7 is a cross-sectional view taken along line BB of the mobile terminal cover 10 shown in FIG.

  As shown in FIGS. 3 to 7, the mobile terminal cover 10 includes a front part 11, a pair of side parts 12, a top part 13, a back part 14, and a bottom part 15. Moreover, the cover 10 for portable terminals has the storage space 16 prescribed | regulated by each said surface parts 11-15. The storage space 16 is provided for storing the mobile printer 100. Accordingly, the storage space 16 has a shape suitable for the mobile printer 100.

  The opening 16 a is formed to store the mobile printer 100 in the storage space 16. In the present embodiment, since the mobile printer 100 is assumed as a portable terminal to be stored, the opening 16a also functions as a paper supply / discharge port for the mobile printer 100.

  Here, if the opening 16a is disposed too large, the mobile printer 300 stored in the storage space 16 may easily be detached from the space, that is, removed from the mobile terminal cover 10. is there. On the other hand, if the opening 16a is too small, it becomes difficult to feed and discharge the mobile printer 100. Therefore, the opening 16a is set shorter than the width of the mobile printer 100 and larger than the width of the printing paper in the X direction. The opening 16a is set shorter than the depth of the mobile printer 100 in the Y direction.

  In the present embodiment, as shown in each drawing, the opening 16a is formed from the front portion 11 to the upper surface portion 13. This is because the paper feed port and the paper discharge port of the mobile printer 100 are located on the front portion 11 and the upper surface portion 13 side in the state of being stored in the storage space 16, respectively. That is, the opening 16a is not necessarily formed at a position as in the present embodiment. The formation position of the opening 16a can be appropriately changed according to the arrangement position of the paper feed port, the paper discharge port, and the display unit in the mobile printer 100.

  The portable terminal cover 10 is manufactured using an elastic member. In the present embodiment, silicon rubber is assumed as the elastic member. By using such an elastic member, external loads such as impact and contact are effectively absorbed by the elastic member. Therefore, it is possible to reduce the influence of the external load received by the mobile printer 100 stored in the storage space 16.

  When the mobile printer 100 is stored in the mobile terminal cover 10, the elasticity of the material of the mobile terminal cover 10 is used. Specifically, the opening 16 a is temporarily expanded and the mobile printer 100 is inserted into the storage space 16. The mobile printer 100 inserted in the storage space 16 is firmly attached to the inner surface of the cover by the elasticity of the mobile terminal cover 10 and is firmly held.

  Note that the mobile printer 100 stored in the storage space 16 is not necessarily covered by the elastic member over the entire area. That is, it is sufficient that each of the surface portions 11 to 13 and 15 other than the back surface portion 14 that defines the storage space 16 is formed so as to cover at least the end portion of the mobile printer 100. For example, in the present embodiment, a through window 12w is provided at the center of the pair of side surface portions 12. The penetrating window 12w allows the mobile printer 100 housed in the housing space 16 to connect with other external devices with priority or wirelessly via various external connection terminals (not shown) disposed on the side of the printer 100. Allow that. Examples of the external connection terminal include a USB terminal and an infrared port.

  In the storage space 16, a lid region 50 that functions as a battery lid for the battery chamber 110 is formed in a region corresponding to the opposite side of the back surface portion 14. The lid region 50 includes a contact portion 51, a recess 52, and a pair of ribs 53.

  The contact portion 51 is a portion that closes the opening 110 a of the battery chamber 110 by contacting the back surface 130 of the mobile printer 100 stored in the storage space 16. The contact portion 51 shown in FIG. 5 has a shape substantially corresponding to the back surface 130. However, in the portable terminal cover according to the present invention, the contact portion has at least a sufficient shape to close the opening of the battery chamber and is disposed at a position that can reliably close the opening. Good.

  Further, in order to improve the holding and protecting function of the battery used, it is desirable that the contact portion 51 has a surface shape that is in close contact with the back surface 130. For example, when the back surface 130 has a three-dimensional striped shape, it is preferable to provide the contact portion 51 with a concavo-convex shape that matches the stripe shape.

  The concave portion 52 is a portion for accommodating the apex angle portion 332 protruding from the battery chamber 110 when the mobile printer 100 with the large-capacity battery 330 attached is accommodated in the mobile terminal cover 10. Here, the recess 52 does not simply store the apex angle portion 332 but needs to appropriately hold and protect the apex angle portion 332. Therefore, as shown in FIG. 7, the recess 52 is configured such that the cross-sectional shape in the YZ plane has a V shape so that the apex angle portion 332 fits. That is, the shape of the opening 52 a of the recess 52 is substantially equal to the opening 110 a of the battery chamber 110. Or the opening 52a of the recessed part 52 may be a slightly reduced shape rather than the opening 110a of a battery chamber, considering that the cover 10 for portable terminals is made of an elastic member.

  The pair of ribs 53 are the ends of the opening 52 a of the recess 52, and are formed along the longitudinal direction (X direction) of the recess 52. The pair of ribs 53 has a shape protruding in the depth direction (Y direction) of the stored mobile printer 100. The pair of ribs 53 restricts the normal battery 310 from entering the recess 52 when the normal battery 310 is stored in the battery chamber 110 of the mobile printer 100 stored in the storage space 160.

  Further, in the present embodiment, the cross-sectional shape is more specifically different from the shapes of the normal battery 310 and the large capacity battery 330. Therefore, the slope itself forming the recess 52 also has a function of restricting entry of the battery 310 into the recess 52. That is, as shown in FIG. 2, when using a large-capacity battery 330 whose cross-sectional shape is not normally a shape obtained by simply extending the battery 310, the slope of the recess 52 functions as an entry restricting means. It is not necessary to provide it. Thereby, the cover 10 for portable terminals can be made into a simple structure, and manufacturing cost can be held down.

  FIG. 8A is a cross-sectional view in the YZ plane of the mobile terminal cover 10 that houses the mobile printer 100 when the normal battery 310 is used. FIG. 8B is a cross-sectional view in the YZ plane of the mobile terminal cover 10 that houses the mobile printer 100 when the large-capacity battery 330 is used. 8A and 8B, for convenience of explanation, a small space is provided between the mobile printer 100 and the mobile terminal cover 10, but in reality, both are in close contact as described above. . That is, the back surface 130 of the mobile printer 100 stored in the storage space 16 is in close contact with the contact portion 51. The same applies to the following drawings.

  As shown in FIG. 8A, when storing the mobile printer 100 when the normal battery 310 is used, the mobile terminal cover 10 is urged by the pair of ribs 53 so that the normal battery 310 is held in the battery chamber 110. ing. In addition, if an external load such as a relatively large vibration is applied to the mobile terminal cover 10 (the mobile terminal cover 10), the normal battery 310 deforms the rib 53 and tries to enter the recess 52. Access is limited by the slope forming 52. That is, when the battery 310 is normally used, entry into the recess 52 is limited by the inclined surfaces of the rib 53 and the recess 52, and the holding in a stable state is guaranteed.

  Further, as shown in FIG. 8B, when the mobile printer 100 is stored when the large-capacity battery 330 is used, the portable terminal cover 10 has a large capacity, particularly by fitting the apex portion 332 into the recess 52. The battery 330 is securely held.

  Further, as shown in FIGS. 8A and 8B, the battery is properly covered with the battery chamber 110 and the elastic lid region 50 even when any battery is used. Therefore, the battery is sufficiently protected against an external load, and the risk of damage is reduced.

  The above is the description of the embodiment of the present invention. Next, some modifications of the above embodiment will be described. Each modified example has a configuration different from that of the above embodiment, but has an effect equal to or greater than that of the above embodiment.

  FIG. 9 is a YZ sectional view showing a lid region 50 of a modified example. FIG. 10A is a YZ sectional view of a mobile terminal cover 10 of a modified example in which the mobile printer 100 is housed when the normal battery 310 is used. FIG. 10B is a YZ cross-sectional view of a mobile terminal cover 10 of a modified example in which the mobile printer 100 is stored when the large capacity battery 330 is used. The modification shown in FIG. 9 has, as an alternative to the rib 53, a rib 54 that extends in the X direction so as to narrow the opening 52 a of the recess 52. As shown in FIG. 10A, by providing the rib 54, the normal battery 310 is effectively prevented from jumping out of the battery chamber 110 (that is, entering the recess 52). As shown in FIG. 10B, when the large capacity battery 330 is used, the rib 54 is deformed and the large capacity battery 330 is allowed to enter the recess. Therefore, as in the above embodiment, the battery chamber 110 and the recess 52 are securely held.

  As shown in FIG. 9, the lid region 50 of the present modification has a rib 54 that narrows the opening 52a. Therefore, unlike the above embodiment, the large-capacity battery 330 can be used even when the cross-sectional shape of the large-capacity battery 330 is usually a shape obtained by extending the cross-sectional shape of the battery 310, that is, the protruding portion is a shape obtained by extending the base portion. it can.

  Furthermore, in the above description, the mobile terminal cover 10 having the lid region 50 in part has been described. Here, if it is not necessary to protect the entire portable terminal such as a mobile printer, a battery lid that allows only the lid region 50 to be extracted and securely attached to the terminal without being displaced and removed safely. You may comprise as.

  Further, the above-described battery is not limited to the normal battery and the large capacity battery as described in the embodiment. The present invention can be applied to any portable terminal that can use a normal battery and a special battery that is larger than the normal battery and has a different cross-sectional shape.
