Description

  The present invention relates to a dry battery storage structure, and more particularly to a battery storage structure suitable for a remote control device used for remotely operating an electronic device.

  Conventionally, for example, electronic devices such as a television receiver, a recording / playback device, and an air conditioner can generally be remotely operated by a remote control device. In general, a remote control device provided for performing remote operation of an electronic device is driven using a dry battery (for example, an AA battery or an AAA battery) housed in a housing as a power source.

  In remote control devices, a plurality of dry batteries as power sources are often housed. In that case, the dry batteries housed in the casing are arranged in parallel or in series. The replacement of the dry batteries used in the remote control device is performed by the user, and it is an essential condition for the remote control device that the user can easily insert and remove the dry batteries regardless of the arrangement.

  Incidentally, in recent years, there is a strong demand for downsizing of the remote control device. In view of these points, it is conceivable to use as small a dry battery as possible for the remote control device. For example, it is conceivable to adopt an AAA battery having a smaller size than an AA battery. Further, in order to narrow the width of the remote control device, it is conceivable that the dry batteries stored in the housing are arranged in series.

  If the dry batteries arranged in the casing of the remote control device are arranged in series, as shown in FIG. 11, the number of battery springs 101 that come into contact with the electrodes of the dry battery 100 can be reduced as compared with the parallel arrangement. Cost reduction can be expected. From this point of view, it may be preferable to arrange the dry batteries stored in the housing in series. In FIG. 11, the left side is a view when the dry cells 100 are arranged in parallel, and the right side is a view when the dry cells 100 are arranged in series. In the case of the parallel arrangement, three battery springs 101 are required, but in the case of the series arrangement, only two battery springs 101 are required.

  However, it has been found that when the configuration in which the AAA batteries are arranged in series in the remote control device is adopted, it is very difficult to take out the dry batteries, particularly when the depth of the battery storage portion for storing the dry batteries is deep. FIG. 12 is a diagram for explaining a problem when the AAA batteries are arranged in series in the remote control device. As shown in FIG. 12, the battery storage unit 201 that stores the dry battery 100 has a width W that is substantially the same as the width w of the dry battery 100 in order to ensure the fixation of the dry battery 100. Here, the width w of the battery of the AAA battery is determined to be 10.5 mm according to the standard, and the width W of the battery storage unit 201 is also approximately 10.5 mm.

  By the way, when the dry battery 100 is taken out from the battery storage unit 201 of the remote control device 200, the tip of the index finger or thumb is usually hooked on the end of the dry battery 100 and taken out. In the case of an adult male, for example, the width on the tip side of the index finger is about 13 mm, and the width on the tip side of the thumb is about 17 mm. For this reason, when the battery storage unit 201 is configured as shown in FIG. 12, the width W (about 10.5 mm) of the battery storage unit 201 is too narrow to put a finger in the battery storage unit 201, and the dry battery It was found that taking out 100 was very difficult.

  On the other hand, referring to the configurations of Patent Documents 1 and 2, a guide groove for inserting a finger is provided on the side surface of the battery storage unit 201, and the dry battery 100 is taken out by hooking the finger on the side surface of the dry cell 100. Can be considered. However, if such a guide groove is provided, it is necessary to increase the size of the remote control device in the width direction or to place the battery storage unit 201 close to one side in the width direction. Increasing the size in the width direction may not be able to adopt such a configuration, contrary to the purpose of reducing the size of the remote control device. Further, when the position of the battery storage unit 201 is moved to one side in the width direction, there may be a problem in that the position of the center of gravity of the remote control device and the circuit configuration are uneven.

  Accordingly, an object of the present invention is to provide a battery housing structure in which a dry battery can be easily taken in and out even when a plurality of dry batteries are arranged in series. It is another object of the present invention to provide a remote control device that includes a battery storage unit in which a plurality of dry batteries are arranged in series and is easy to insert and remove the dry batteries.

Provided on one end side of both ends And a second portion that forms a space in which a small portion of the plurality of dry cells is accommodated, and the first portion has an interval that is substantially the same as the width of the dry cell in the second direction. A pair of first walls arranged opposite to each other, and the second portion is arranged to face the second direction with a larger interval than the distance between the pair of first walls in the second direction. It is characterized by having a wall.

  According to this structure, the part wider than the width | variety of a dry cell is provided in the edge part side of a battery accommodating part. For this reason, it becomes possible to take out a dry battery by putting a finger of a person wider than the width of the dry battery into the battery housing and hooking the finger on the end of the dry battery. And in this structure, taking out a dry battery is made easy by devising the storage structure of the part in which a dry cell is accommodated, without providing a groove | channel etc. in the outer side of the part in which a dry battery is accommodated.

Thereby, it is possible to prevent the deviation of the center of gravity and the deviation of the circuit configuration of the remote control device. In the conventional technology, there is a concern about the size of the remote control device when it is intended to realize a configuration in which the battery storage portion is provided in the substantially central portion of the casing and the battery can be easily taken out. According to this, such a concern about an increase in the size of the remote control device can be solved.

  In the remote control device having the above configuration, the dry battery may be a AAA battery. The width of the AAA battery is narrower than the width of a person's finger, and it tends to be difficult to remove the dry battery from the battery compartment of the remote control device. However, in this configuration, the dry battery can be easily taken out even if the dry battery stored in the battery storage portion of the remote control device is a AAA battery.

  In order to achieve the above object, the battery storage structure of the present invention is a battery storage structure when a dry battery is stored in a battery storage part, and is substantially parallel to the longitudinal direction of the dry battery stored in the battery storage part. The first direction, the second direction of the dry battery housed in the battery housing portion being the second direction, the direction being substantially parallel to the bottom surface of the battery housing portion and substantially perpendicular to the first direction. When the width in the direction is the width of the dry battery, the battery storage portion includes a first portion that forms a space in which most of the dry battery is stored, and the first direction of the battery storage portion. A second portion that is provided on one end side of the both end portions and forms a space in which a small portion of the dry cell is stored, and the first portion extends in the second direction. Having a pair of first walls arranged opposite to each other with an interval substantially the same as the width of the dry cell The second portion is characterized by having a pair of second walls disposed opposite at a greater distance than the spacing of the pair of first walls to said second direction.

  According to this structure, the part wider than the width | variety of a dry cell is provided in the edge part side of a battery accommodating part. For this reason, it becomes possible to take out a dry battery by putting a finger of a person wider than the width of the dry battery into the battery housing and hooking the finger on the end of the dry battery. And in this structure, taking out a dry battery is made easy by devising the storage structure of the part in which a dry cell is accommodated, without providing a groove | channel etc. in the outer side of the part in which a dry battery is accommodated. For this reason, in a battery driving device (for example, a remote control device) driven by a dry battery, it is possible to easily insert and remove the dry battery without increasing the size.

  In the battery housing structure configured as described above, the second wall includes a convex curved surface portion adjacent to the first wall, and a flat surface portion adjacent to the curved surface portion and provided at a position away from the first wall. It is preferable to have.

  The remote control device 1 of the present embodiment has a top case 2 and a bottom case 3 as outer shells. The top case 2 and the bottom case 3 are fixed to each other by engagement hooks and screws (not shown). Further, as shown in FIG. 4, a key rubber 6 in which a plurality of button-shaped operation keys 4 are formed and a remote control device 1 of the remote control device 1 are formed inside the casing formed by overlapping the top case 2 and the bottom case 3. A circuit board 7 on which an electric circuit (not shown) necessary for operation is formed, a transmitter 5 for transmitting an infrared signal (not shown in FIG. 4, but a part of the transmitter 5 is exposed in FIG. 2) A dry battery 10 serving as a power source of the remote control device 1 is accommodated.

  A plurality of through holes are formed in the top case 2 of the remote control device 1, and the operation key 4 is exposed from each through hole. Each operation key 4 is slightly lifted from the circuit board 7 on which the key rubber 5 is overlaid, and a switch contact (not shown) is provided at a position corresponding to the operation key of the circuit board 7 immediately below. It has been. Thereby, when the user presses the operation key, the switch contact is connected, and a command signal (infrared signal) assigned thereto is transmitted from the transmitter 5 arranged on the front side of the remote control device 1. The transmitted signal is received by a signal light receiving unit (not shown) of the electronic device to be operated, and the electronic device operates based on the received signal.

  As shown in FIG. 3, an opening 3 a for inserting the dry battery 10 is formed on the bottom surface of the bottom case 3 of the remote control device 1. The remote control device 1 is configured to use two dry batteries 10 (specifically, AAA batteries) as a power source, and the two dry batteries 10 are arranged in series in a casing (top case 2 and bottom case 3). The same holds true for the following). The details of the configuration of the battery storage unit 8 will be described later.

  The opening 3 a provided for inserting the dry battery 10 is covered with a lid 12 so that the dry battery 10 does not fall out of the battery storage part 8 after the dry battery 10 is inserted into the battery storage part 8 of the remote control device 1. ing. As shown in FIG. 5, the lid portion 12 has a substantially rectangular flat plate portion 121, two projections 122 are provided at one end portion of the flat plate portion 121, and elastic deformation at the other end portion. An elastic deformation portion 123 is provided. In addition, a battery pressing portion 125 is formed on the lower surface of the lid portion 12 to restrict the dry battery 10 stored in the battery storage portion 8 from being lifted in a state where the lid portion 12 is attached to the bottom case 3.

  In attaching the lid 12 to the bottom case 3, first, the lid 12 is inclined so that the protrusion 122 enters the inside of the bottom case 3 from the opening 3 a of the bottom case 3. In this case, the lid portion 12 is arranged so that the elastic deformation portion 123 is on the front side of the housing and the protrusion 122 is on the rear surface side of the housing. Next, the elastic deformation portion 123 is pushed down so as to engage with the engagement groove 9 (formed on the front surface side of the housing) of the bottom case 3 with the protruding portion 122 entering the inside of the bottom case 3. . The pushed-down elastically deforming portion 123 enters the engaging groove 9 while being elastically deformed. When pushed down to a desired position, the elastically deforming portion 123 returns to its original state, and the engaging end 123a is provided in the engaging groove 9. Engages with an engaging portion (not shown). Thereby, the lid portion 12 is fixed so as not to be detached from the bottom case 3.

  Note that a handle portion 124 is formed in the elastic deformation portion 123, and the engagement state of the engagement end 123 a can be released by elastically deforming the elastic deformation portion 123 by the handle portion 124, so that the bottom case 3 The attached lid 12 can be easily removed.

(Configuration of battery compartment)
As described above, the remote control device 1 accommodates the AAA batteries (dry batteries) 10 in series. When small batteries such as AAA batteries are housed in series, it may be difficult to remove the batteries from the battery housing as mentioned above. In particular, in the remote control device 1 of the present embodiment, as shown in FIG. 4, the dry battery 10 is stored at a deep position from the bottom surface of the bottom case 3 (upward in FIG. 4). Is difficult to remove the dry battery 10 from the battery housing 8. However, in the remote control device 1 of the present embodiment, the structure of the battery housing portion 8 is devised so that such a small dry battery 10 can be easily taken out from the battery housing portion 8. Hereinafter, the configuration of the battery storage unit 8 will be described in detail.

  The storage space of the battery storage portion 8 provided in the housing of the remote control device 1 is formed on the plate surface 7a (see FIG. 4) of the circuit board 7 and the bottom case 3, and the top case 2 is covered with the bottom case 3. This is a space surrounded by walls (indicated by reference numerals 83a and 83b in FIG. 4) provided so as to stand upright with respect to the plate surface 7a. In other words, the plate surface 7 a of the circuit board 7 is the bottom surface of the battery housing portion 8, and the wall formed on the bottom case 3 is the side wall of the battery housing portion 8.

  FIG. 6 is a schematic plan view for explaining the configuration of the battery housing unit provided in the remote control device of the present embodiment, and is a view of the remote control device as seen from the bottom side. As shown in FIG. 6, the side wall of the battery storage unit 8 includes a front wall 81, a rear wall 82, a pair of first horizontal walls 83 a and 83 b, and a pair of second horizontal walls 84 a and 84 b. The pair of first lateral walls 83a and 83b is an embodiment of the first wall of the present invention, and the pair of second lateral walls 84a and 84b is an embodiment of the second wall of the present invention.

  FIG. 6 shows a state where the lid 12 is removed. Further, since the rear wall 82 and a part of the pair of first horizontal walls 83a and 83b are inside the housing even when the cover 12 is removed, these are shown by thin broken lines in FIG. .

  The front wall 81 and the rear wall 82 are in a substantially parallel relationship with each other, and the distance between the two is the longitudinal direction when the two dry batteries 10 are arranged in series (the same as the first direction of the present invention). It is almost the same as the length. Further, a battery spring (not shown) for the positive electrode of the dry battery 10 is attached to the front wall 81, and a battery spring (not shown) for the negative electrode of the dry battery 10 is attached to the rear wall 82. Yes. For this reason, in the remote control device 1, when the dry battery 10 is stored in the battery storage unit 8, the two dry batteries 10 are aligned so that the front wall 81 side is positive and the rear wall 82 side is negative. It will be stored in the part 8.

  The pair of first horizontal walls 83a and 83b are opposed to each other in a second direction substantially parallel to the bottom surface of the battery storage unit 8 and substantially orthogonal to the above-described longitudinal direction (first direction) with a predetermined interval W1. Has been placed. This constant interval W1 is an interval (specifically, about 10.5 mm) that is substantially the same as the width of the dry battery 10. The term width of the dry battery 10 is used as a term indicating the width in the second direction of the dry battery 10 housed in the battery housing portion 8.

  The pair of second horizontal walls 84a and 84b are disposed to face each other in the second direction described above with a gap larger than the gap W1 between the pair of first horizontal walls 83a and 83b. The pair of second horizontal walls 84a and 84b is one end of both end portions (the end portion on the front wall 81 side and the end portion on the rear wall 82 side) in the longitudinal direction (first direction) of the battery storage portion 8. Is provided on the side (end on the front wall 81 side) side.

  More specifically, the pair of second horizontal walls 84a and 84b are respectively adjacent to the convex curved walls 841a and 841b adjacent to the first horizontal walls 83a and 84b and the convex curved walls 841a and 841b. Plane walls 842a and 842b provided at positions distant from 83a and 83b. The planar walls 842a and 842b are adjacent to the front wall 81.

  The pair of curved walls 841a and 841b are R-shaped curved surfaces, and the interval W2A between the pair of curved walls 841a and 841b increases as the distance from the front wall 81 increases. On the other hand, the interval W2B between the pair of flat walls 842a and 842b is a constant interval. This interval W2B is designed so that the index finger or the tip of the thumb can be inserted when the dry battery 10 is taken out. More specifically, W2B is set to about 20 mm as a width larger than the width of the tip portion of the index finger and thumb of a general adult male.

  Note that the width in the first direction of the planar walls 842a and 842b is preferably as narrow as possible within the range in which the dry battery 10 can be easily taken out.

  As described above, the battery storage unit 8 includes the rear wall 82 and the pair of first lateral walls 83a and 83b, the first portion 8a that forms a space in which most of the two dry batteries 10 are stored, and the front surface It includes a wall 81 and second lateral walls 84a and 84b, and has a second portion 8b in which small portions of the two dry batteries 10 are accommodated. The thick broken line in FIG. 6 is an imaginary line indicating the boundary between the first portion 8a and the second portion 8b. The first portion 8a is below the thick broken line, and the second portion 8b is above the thick broken line.

  The first portion 8a has a distance W1 between the pair of first walls 83a and 83b that is substantially the same as the width of the dry cell 10, and holds the dry cell 10 stored in the battery storage unit 8 so as not to move within the housing. It has a function. Further, the second portion 8b has a function of making it easier to hook the dry battery 10 with the index finger or the tip of the thumb when taking out the dry battery 10 stored in the battery storage unit 8.

  Here, in the battery housing part 8 of the remote control device 1 of the present embodiment, the reason why the convex curved walls 841a and 841b are provided on the second lateral walls 84a and 84b of the second portion 8b with reference to FIG. Let me explain. FIG. 7 is a diagram for explaining the reason why a curved wall is provided on the second lateral wall in the remote control device of this embodiment, and FIG. 7A is a second view of the battery storage unit in the remote control device of this embodiment. FIG. 7B is an enlarged view showing a part periphery, and is a diagram for comparison with the present embodiment.

  The second portion 8b of the battery storage unit 8 is provided to facilitate removal of the dry battery 10 as described above. For this purpose, as shown in FIG. 7B, the second lateral walls 84a and 84b may be configured by only the flat walls 842a and 842b without providing the convex curved walls 841a and 841b ( This configuration is also included in the scope of the present invention). However, in the configuration shown in FIG. 7B, when the dry battery 10 is inserted into the battery housing portion 8, it is difficult to insert the dry battery 10 by being caught on the plane 85 substantially orthogonal to the first horizontal walls 83 a and 83 b. Further, the force tends to concentrate on the edge portion 86, and for example, when the remote control device 1 is dropped, the edge portion 86 is easily broken.

  In order to improve this point, in the battery housing part 8 of the remote control device 1 of the present embodiment, convex curved walls 841a and 841b are provided on the second horizontal walls 84a and 84b of the second portion 8b. By configuring in this way, it is possible to suppress catching when the dry battery 10 is inserted into the battery housing portion 8 and damage to the battery housing portion 8.

  FIG. 8 is an enlarged perspective view showing the configuration in the vicinity of the support portion in the remote control device of the present embodiment. FIG. 9 is an explanatory diagram for explaining the effect of providing a support in the remote control device of this embodiment. FIG. 9A shows the configuration of this embodiment, and FIG. 9B is for comparison. It is the figure which showed the structure at the time of having no support part.

  In the remote control device 1 of the present embodiment, as shown in FIG. 8, a support portion 13 that supports the lid portion 12 attached to the bottom case 3 is provided outside the battery housing portion 8 and in the vicinity of the second portion 8 b. Provided. More specifically, the support portion 13 is provided on the left and right sides of the engagement groove 9 into which the elastic deformation portion 123 (see FIG. 5) of the lid portion 12 is fitted, and has a contact surface that contacts the lower surface of the lid portion 12. It has a configuration.

  In the case where the support portion 13 is not provided, in the remote control device 1 according to the present embodiment, the second portion 8b is provided in the battery storage portion 8, and as shown in FIG. There will be no part that supports the front side. For this reason, the lid 12 attached to the bottom case 3 becomes unstable.

  The support portion 13 is provided to eliminate such instability. That is, as shown in FIG. 9A, in the configuration of the present embodiment, the lid 12 is supported by the support 13 at the two corners 12a and 12b closer to the front surface, and the first wall 83a, A part thereof is also supported by the upper side (upper surface) of 83b and the upper side (upper surface) of the curved walls 841a and 841b of the second walls 84a and 84b. Thereby, the cover part 12 is firmly supported by the bottom case 3, and the instability of the cover part 12 mentioned above can be eliminated.

  In the remote control device 1 of the present embodiment, two support portions 13 are provided, but it is only necessary to stably support the front side of the lid portion 12, and the position where the contact surface is provided and the number of contact surfaces are changed as appropriate. Is possible.

  By the way, the battery storage unit 8 included in the remote control device 1 of the present embodiment has a predetermined length from the rear wall 82 toward the front wall 81 so that the upper surface of the battery storage unit 8 covers the bottom case 3 instead of the lid 12. (See FIG. 6). The reason for this configuration is to facilitate storage of the first dry battery 10 in the battery storage portion 8 when two dry batteries 10 are stored in series in the battery storage portion 8.

  When the battery storage unit 8 is configured as described above, it is possible to provide the remote control device 1 that allows easy insertion and removal of the plurality of dry batteries 10 arranged in series and is easy for the user to use. In particular, when the dry battery 10 is stored in the battery storage unit 8 and the height of the dry battery 10 is lower than the side walls 81, 82, 83 a, 83 b, 84 a, 84 b of the battery storage unit 8, the battery of the dry battery 10 is used. Although there is a tendency that it is difficult to remove from the storage unit 8, the difficulty is solved by the storage structure of the battery storage unit 8 of the present embodiment.

  Further, it is preferable to provide the battery housing portion 8 at a substantially central portion of the casing of the remote control device 1 as much as possible so that the bias of the center of gravity of the remote control device 1 and the bias of the circuit configuration do not occur. If it is attempted to reduce the size of the remote control device 1 (especially to narrow the width direction) while satisfying such a condition, it is difficult to provide a guide groove on the side of the battery housing portion 8. In this regard, according to the configuration of the present embodiment, it is possible to further reduce the size of the remote control device while disposing the battery housing portion 8 at a substantially central portion of the housing.

(Other)
The embodiment described above is an exemplification, and it goes without saying that the scope to which the present invention is applied is not limited to the configuration of the embodiment described above.

  For example, the configuration of the second portion 8b having the pair of second lateral walls 84a and 84b is not limited to the configuration of the above-described embodiment, and the tip portion of the index finger or thumb is hooked on the dry battery 10 to be taken out. Other configurations may be used as long as they are easy to remove. That is, for example, as shown in FIG. 10 (a), the second horizontal walls 84a and 84b are formed only by plane walls, and the plane walls are arranged obliquely with respect to the first horizontal walls 83a and 83b. You may comprise so that the space | interval W2 between a pair of 2nd horizontal wall 84a, 84b may increase as it approaches 81. As shown in FIG. Further, as shown in FIG. 10B, a pair of second lateral walls 84a and 84b having a width wider than the interval W1 between the pair of first lateral walls 83a and 83b is provided only on the upper side of the first portion 8a. The lower side may be configured to provide a wall having the same width as the pair of first horizontal walls 83a and 83b.

  Further, in the present embodiment, the number of the dry batteries 10 stored in series in the battery storage unit 8 is two, but the present invention can be applied even when there are three or more. The type of the dry cell 10 stored in the battery storage unit 8 is not limited to the AAA battery, but the present invention is applied to a battery storage unit that stores a dry cell having a width smaller than that of the index finger or the thumb. It can be suitably applied.

  In addition, the battery storage structure of the present invention can be applied to a dry battery driving device that drives a dry battery other than the remote control device as a power source. In addition, the battery storage structure of the present invention is applicable even when only one dry battery is stored in the battery storage unit.

  The present invention is suitable for a remote control device used for remotely operating electronic devices such as a television receiver, a recording / reproducing device, and an air conditioner.
