Description

[Technical field]

[0001] The present disclosure relates to electronic devices. [Background technology]

[0002] Conventionally, there are known portable electronic devices (e.g., telemeters) that use dry batteries as a power source. In such electronic devices, a battery cover is generally attached to a main body case of the electronic device so that the user can replace the dry batteries. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-025941 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, this type of electronic device has a lever part (e.g., a rotatable handle supported by bearings) and a spring that biases the lever part, etc., arranged inside the main body case to enable the battery cover attached to the main body case to be switched between an unlocked state and a locked state (see, for example, Patent Document 1).

[0005] However, in such electronic devices, the lever part is configured to be movable within the main case, so the main case needs to be designed to be large enough to accommodate the lever part and to accommodate the movable space of the lever part, which is an obstacle to reducing the size of the device. Also, electronic devices having multiple parts need to be improved in terms of the need to reduce the number of parts.

[0006] On the other hand, in electronic devices relating to the prior art, the dry cell battery is directly inserted into the battery storage groove formed in the main body case, so when replacing the dry cell battery, the user must insert their finger into the battery storage groove and remove the dry cell battery from there, leaving room for improvement in terms of the ease of replacing the dry cell battery.

[0007] The present disclosure has been made in consideration of the above problems, and has an object to provide an electronic device that can realize a more suitable structure for attaching and detaching a dry cell. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functions are denoted by the same reference numerals, and redundant description will be omitted.

[0012] [Telemetry configuration] In the following, an embodiment of the electronic device according to the present invention will be described in which it is applied to a telemeter (hereinafter, referred to as "telemeter 1"). However, the electronic device according to the present invention can be applied to devices other than telemeters. In particular, the electronic device according to the present invention is suitable for small portable electronic devices such as mobile phones, digital cameras, or portable medical devices (e.g., Holter recorders).

[0013] Fig. 1 is a diagram showing the external appearance of a telemeter 1. Fig. 2 is a perspective view showing a state in which a battery holder 20 is removed from a main body case 10 of the telemeter 1.

[0014] 3, 4 and 5 are perspective views showing the configuration of the main body case 10 of the telemeter 1. Fig. 6 is a perspective view showing the configuration of the push button section 14 attached to the main body case 10 of the telemeter 1.

[0015] 7 and 8 are perspective views showing the configuration of the battery holder 20 (FIG. 7 shows a state in which a dry battery B is installed, and FIG. 8 shows a state in which the dry battery B is not installed).

[0016] In each figure, a common Cartesian coordinate system (X, Y, Z) is shown to clarify the positional relationship of each component. In the following description, the positive direction of the X-axis represents the front direction of the telemeter 1 (hereinafter abbreviated as "front direction"), the positive direction of the Y-axis represents the width direction of the telemeter 1 (hereinafter abbreviated as "width direction"), and the positive direction of the Z-axis represents the upward direction of the telemeter 1 (hereinafter abbreviated as "upward direction"). However, these directions do not limit the posture of the telemeter 1 of the present invention when in use.

[0017] The telemeter 1 is, for example, an electronic device that is carried by a user, acquires the user's biological signals (e.g., information related to arterial blood oxygen saturation and heart rate) sensed by an external sensor device (not shown) via a cable, processes the biological signals, and then transmits them via wireless communication to an external monitor device (not shown).

[0018] The telemeter 1 includes a main body case 10 and a battery holder 20 attached to the main body case 10.

[0019] The telemeter 1 uses a dry battery B (e.g., a manganese dry battery, an alkaline dry battery, or a nickel-cadmium dry battery) as a power source that supplies power to various module components housed in the main body case 10. In the telemeter 1 according to this embodiment, the dry battery B is housed in the main body case 10 while being attached to a battery holder 20 (see FIG. 2). The telemeter 1 according to this embodiment is equipped with two cylindrical AA dry batteries.

[0020] First, the configuration of the main body case 10 will be described.

[0021] The main body case 10 is, for example, a box having a substantially rectangular parallelepiped shape, and houses a circuit board (for example, a printed circuit board) equipped with various modular components that perform various signal processing. The main body case 10 is formed, for example, from an insulating resin material (for example, ABS resin or PBT resin). The main body case 10 is configured such that the internal space is sealed when the battery holder 20 is attached to the battery storage groove 11.

[0022] The main body case 10 includes a battery storage groove 11, an electrode member 12, a claw portion 13, a push button portion 14, an engagement hole 15, an external input / output terminal 16, and the like.

[0023] The battery storage groove 11 is a groove area for storing dry batteries B inside the main body case 10. The battery storage groove 11 has a shape that corresponds to the dry batteries B (here, two AA dry batteries), for example. The battery storage groove 11 also has a step portion 11c around the entire periphery of the edge area (see FIG. 3). The step portion 11c has a shape that corresponds to a step portion 20aa (see FIG. 8) formed on the mounting surface 20a of the battery holder 20 so that the battery holder 20 can fit into the battery storage groove 11.

[0024] The electrode member 12 (hereinafter referred to as "case-side electrode member 12") is a member for electrically connecting with the terminals (positive and negative terminals) of the dry battery B (see FIG. 4).

[0025] In the telemeter 1 according to this embodiment, the dry battery B is mounted in the battery holder 20, and the terminals of the dry battery B itself come into contact with an electrode member 21 (hereinafter referred to as the "holder side electrode member 21") (see FIG. 7) arranged in the battery holder 20. That is, the case side electrode member 12 is arranged at a position on the bottom surface of the battery housing groove 11 that comes into contact with the holder side electrode member 21 when the battery holder 20 is mounted in the main body case 10. The case side electrode member 12 comes into contact with the holder side electrode member 21 and transmits the power supplied from the dry battery B to a circuit board or the like arranged in the main body case 10.

[0026] A pair of case side electrode members 12 are provided corresponding to the positive and negative electrodes, respectively, and are disposed so as to abut against the positive and negative electrode members of the holder side electrode members 21, respectively.

[0027] The case side electrode member 12 is, for example, a spring pin connector (corresponding to the "elastic member" of the present invention) with a pin facing upward. That is, the case side electrode member 12 is arranged so as to bias the holder side electrode member 21 when the battery holder 20 and the main body case 10 are fixed. This ensures a stable electrical connection between the case side electrode member 12 and the holder side electrode member 21. This also ensures that when the fixed state between the battery holder 20 and the main body case 10 is released, the elastic force of the case side electrode member 12 in the upward direction (positive Z direction) causes the battery holder 20 to spring up from the main body case 10, improving the ease of removal of the battery holder 20 from the main body case 10.

[0028] The claw portion 13 is a protruding structure formed on a first side surface 11a (here, the side surface on the negative X direction side) of the battery housing groove 11. More specifically, the claw portion 13 protrudes in the positive X direction from the first side surface 11a of the battery housing groove 11. The claw portion 13 is formed integrally with the main body case 10 from a resin material, for example.

[0029] The claw portion 13 is formed at a position facing an opening 24 formed in the protrusion 23 of the battery holder 20 when the battery holder 20 is fitted into the battery housing groove 11. The claw portion 13 is formed to fit into the opening 24 when the battery holder 20 is fitted into the battery housing groove 11 (see FIG. 10).

[0030] The push button 14 is a push button formed on the first side surface 11a (here, the side surface on the negative X-direction side) of the battery housing groove 11 so as to be pressable from the outside of the main body case 10. More specifically, the push button 14 is disposed on the first side surface 11a of the battery housing groove 11 at a position facing the protrusion 23 of the battery holder 20 (here, a position directly below the claw portion 13) when the battery holder 20 is fitted into the battery housing groove 11.

[0031] The push button section 14 is formed of an elastic member (e.g., a rubber member). The push button section 14 has a base section 14b and a protrusion section 14a protruding from the base section 14b (see FIG. 6). The push button section 14 is disposed such that the base section 14b is fitted and fixed in a through hole formed in the main body case 10, and the protrusion section 14a protrudes from the first side surface 11a on the inner side of the battery housing groove 11.

[0032] Push button 14 is elastically deformed by being pressed, and moves so as to protrude from first side surface 11a toward the inside of main case 10 (here, the positive X direction). That is, when a pressing force is applied to push button 14, push button 14 moves so as to protrude from first side surface 11a toward the inside of main case 10 (here, the positive X direction), and accordingly comes into contact with protrusion 23 of battery holder 20, causing protrusion 23 to move toward the inside of main case 10. As a result, claw 13 of main case 10 comes out of opening 24 of battery holder 20, and the fixed state between battery holder 20 and main case 10 is released (see FIG. 11).

[0033] The engagement hole 15 is a hole formed in the second side surface 11b (here, the side surface on the positive Y direction side, in the area above the step portion 11c) opposite the first side surface 11a of the battery storage groove 11 (see Figure 5).

[0034] The engagement hole 15 is formed to temporarily fix the battery holder 20 to the main case 10 when the battery holder 20 is fitted into the battery storage groove 11, and has a hole shape that fits with an engagement claw 22 (see FIG. 7) formed on the battery holder 20. That is, when attaching the battery holder 20 to the main case 10, first, the engagement claw 22 formed on the battery holder 20 is inserted into the engagement hole 15, and with the front end (end on the positive X side) of the battery holder 20 temporarily fixed to the main case 10, the rear end (end on the negative X side) of the battery holder 20 is lowered downward (in the negative Z direction) until the battery holder 20 is fitted into the battery storage groove 11 (see FIG. 9).

[0035] The external input / output terminal 16 is an electric connector to which a cable extending from a sensor device (not shown) that measures a biosignal of a user is connected (see FIG. 1). For example, one end of the external input / output terminal 16 is exposed from a side surface of the main body case 10 (here, the side surface on the positive X direction side) and a cable is connected. The other end of the external input / output terminal 16 has a pin soldered to a circuit board housed in the main body case 10. The biosignal input to the external input / output terminal 16 is subjected to signal processing by various module components mounted on the circuit board.

[0036] Next, the configuration of the battery holder 20 will be described.

[0037] The battery holder 20 includes an electrode member 21 (that is, a holder-side electrode member 21), an engagement claw 22, a protrusion 23, an opening 24, and the like.

[0038] The battery holder 20 has a shape that fits into the battery storage groove 11 of the main case 10. More specifically, a step 20aa is formed in the edge region of the mounting surface 20a (i.e., the lower surface) of the battery holder 20, and the step 20aa has a shape that corresponds to the step 11c formed in the battery storage groove 11.

[0039] The holder-side electrode member 21 is configured from a pair of electrode members arranged to face each other and stand upright from the mounting surface 20a of the battery holder 20 (see Figs. 7 and 8). The pair of holder-side electrode members 21 hold the dry battery B by sandwiching it from the left and right, and abut against the positive and negative terminals of the dry battery B. The holder-side electrode member 21 is formed from a plate-shaped electrode member standing upright from the mounting surface 20a, and the plate-shaped electrode member is arranged by bending the upper end. When the battery holder 20 is fitted into the battery storage groove 11, the holder-side electrode member 21 abuts at its upper end against a case-side electrode member 12 (i.e., a spring pin) arranged inside the main body case 10.

[0040] The protrusion 23 is a portion that protrudes from the mounting surface 20a of the battery holder 20 in a direction substantially normal to the surface (see FIG. 8).

[0041] The opening 24 is a through hole formed in the protruding portion 23. The opening 24 has a shape that fits with the claw portion 13 formed on the main case 10 (see FIG. 8). That is, when the battery holder 20 is fitted into the battery storage groove 11, the claw portion 13 of the main case 10 fits into the opening 24 formed in the protruding portion 23 of the battery holder 20, thereby fixing the battery holder 20 and the main case 10 together.

[0042] The engagement claw 22 is formed at a position corresponding to the engagement hole 15 when the battery holder 20 is fitted into the battery storage groove 10 (see FIG. 7). Specifically, the engagement claw 22 is formed in the edge region of the battery holder 20 on the opposite side to the position where the protrusion 23 is disposed, with the dry battery B sandwiched between them. The engagement claw 22 has a convex shape that fits into the engagement hole 15 formed in the main case 10, and protrudes laterally from the battery holder 20 (i.e., in a direction approximately parallel to the plane extension direction of the mounting surface 20a).

[0043] That is, when fitting the battery holder 20 into the battery storage groove 11, first the engagement claws 22 of the battery holder 20 are fitted into the engagement holes 15 of the battery storage groove 11, thereby provisionally fixing the battery holder 20 to the main case 10. This makes it possible to position the battery holder 20 relative to the main case 10 when fitting the battery holder 20 into the battery storage groove 11, and also ensures a stable attachment state of the battery holder 20 to the main case 10.

[0044] The packing member 25 is disposed around the entire periphery of the edge region (i.e., the step portion 20aa) of the mounting surface 20a of the battery holder 20. When the battery holder 20 is mounted in the battery storage groove 11, the packing member 25 comes into contact with the step portion 11c formed in the edge region of the battery storage groove 11, preventing water and other foreign matter from entering the battery storage groove 11 from the outside (see FIG. 8).

[0045] The packing member 25 is typically made of a rubber material, so that when the fixed state between the battery holder 20 and the main case 10 is released, the upward elastic force of the packing member 25 causes the battery holder 20 to jump up from the main case 10.

[0046] Here, the short cross section of the packing member 25 is formed in an arc shape on the exposed surface side (see FIG. 8).

[0047] Specifically, in the past, this type of electronic device used a packing member whose short cross section has a corner on the exposed surface side. However, with a packing member of this shape, when attaching the battery holder 20 to the main body case 10, depending on how the battery holder 20 is attached, there is a possibility that the packing member may be twisted (for example, the packing member may be twisted so as to slip inside the main body case 10).

[0048] In this regard, by using packing member 25 in which the short cross section is formed into an arc shape on the exposed surface side, as in packing member 25 according to this embodiment, the way in which packing member 25 contacts the mating side (here, step portion 11c of battery storage groove 11 of main body case 10) is uniform regardless of how battery holder 20 is attached, and it is possible to prevent twisting of packing member 25. In other words, this makes it possible to prevent deterioration of the waterproof properties due to twisting of packing member 25.

[0049] [Process for attaching and detaching the battery holder 20 to the main body case 10] Next, the process for attaching the battery holder 20 to the main body case 10 and the process for removing the battery holder 20 from the main body case 10 will be described.

[0050] Fig. 9 is a diagram showing the steps for attaching the battery holder 20 to the main body case 10. Fig. 10 is a diagram showing the state in which the battery holder 20 is attached to the main body case 10. Fig. 11 is a diagram showing the steps for removing the battery holder 20 from the main body case 10.

[0051] The process for attaching the battery holder 20 to the main body case 10 is as follows.

[0052] First, the user installs a dry battery B in the battery holder 20. Next, the user moves the front end of the battery holder 20 (the end on the positive X side) diagonally or horizontally (in the negative Y direction) relative to the battery storage groove 11 so that the engagement tab 22 of the battery holder 20 fits into the engagement hole 15 of the main case 10. This causes the engagement tab 22 of the battery holder 20 to fit into the engagement hole 15 of the main case 10, temporarily fixing the battery holder 20 and the main case 10 together (see FIG. 9).

[0053] Thereafter, the user simply lowers the rear end (the end on the negative X side) of the battery holder 20 toward the battery storage groove 11 of the main case 10. This causes the battery holder 20 to fit into the battery storage groove 11. Then, when the user further lowers the rear end (the end on the negative X side) of the battery holder 20 toward the battery storage groove 11 of the main case 10, the claw portion 13 of the main case 10 fits into the opening 24 formed in the protrusion 23 of the battery holder 20, and the battery holder 20 and the main case 10 are fixed together (see FIG. 10).

[0054] In this manner, in the telemeter 1 according to this embodiment, the user can easily attach the battery holder 20 to the main body case 10.

[0055] The steps for removing the battery holder 20 from the main body case 10 are as follows.

[0056] First, the user presses in push button 14 of main case 10. This causes push button 14 to move inwardly into main case 10, and as a result, push button 14 comes into contact with protrusion 23 of battery holder 20. Then, as the user further presses in push button 14 of main case 10, push button 14 moves protrusion 23 of battery holder 20 toward the inside of main case 10. This causes claw 13 of main case 10 to disengage from opening 24 of battery holder 20, and the fixed state between battery holder 20 and main case 10 is released (see FIG. 11).

[0057] At this time, as the fixed state between the battery holder 20 and the main case 10 is released, an upward force (positive Z direction) acts on the battery holder 20 due to the elastic force of the case side electrode member 12 and the elastic force of the gasket member 25, causing the battery holder 20 to jump up from the main case 10.

[0058] In this manner, in the telemeter 1 according to this embodiment, the user can easily remove the battery holder 20 from the main body case 10.

[0059] [effect] As described above, the electronic device according to this embodiment has: a main body case and a battery holder detachably attached to the main body case; The main body case includes: A battery storage groove; a claw portion formed on a first side surface of the battery housing groove; a push button portion that is disposed on the first side surface of the battery storage groove so as to be pressable from the outside of the main body case, and that elastically deforms when pressed against itself, and moves so as to protrude from the first side surface toward the inside of the main body case, The battery holder includes: The battery housing has a shape that fits into the battery housing groove, and a protrusion protruding from a mounting surface of the battery holder in a direction substantially normal to the mounting surface; an opening formed in the protrusion, when the battery holder is fitted into the battery storage groove, the tab of the main body case is fitted into the opening formed in the protrusion of the battery holder, thereby fixing the battery holder and the main body case together; When a pushing force is applied to the push button portion of the main body case, the push button portion moves the protrusion of the battery holder toward the inside of the main body case, thereby disengaging the claw portion of the main body case from the opening of the battery holder, thereby releasing the fixed state between the battery holder and the main body case.

[0060] According to the electronic device of this embodiment, unlike electronic devices relating to conventional technology, the battery holder 20 can be attached and detached to the main body case 10 without the need for lever parts or springs to enable the battery cover to be opened and closed.

[0061] This makes it possible to reduce the size of the electronic device, and in addition, this makes it possible to reduce the number of parts required to manufacture the electronic device, and also makes it possible to suppress an increase in the number of steps required to install the lever part.

[0062] Furthermore, according to the electronic device of this embodiment, the user can complete the replacement of the dry battery B simply by attaching the dry battery B to the battery holder 20 removed from the main body case 10, which also contributes to improving the ease of replacing the dry battery B.

[0063] Although the specific examples of the present invention have been described in detail above, these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples exemplified above. [Industrial Applicability]

[0064] According to the electronic device according to the present disclosure, it is possible to realize a more suitable structure for attaching and detaching a dry cell. [Explanation of symbols]
