[0009] -First embodiment- A first embodiment of the present invention will be described below with reference to Figs. 1A to 9. The holding device according to the first embodiment of the present invention is configured to detachably hold a storage battery (secondary battery) such as a battery. Figs. 1A and 1B are perspective views that show a schematic overall configuration of a holding device 100 according to the first embodiment, Fig. 1A shows a state in which a battery 200 has been removed, and Fig. 1B shows a state in which the battery 200 is housed. For convenience, three axial directions that are mutually orthogonal as shown in the drawings are defined below as the front-rear direction, the left-right direction, and the up-down direction, and the configuration of each part will be described according to these definitions. The up-down direction corresponds to the direction of gravity (also called the vertical direction).

[0010] 1A and 1B, the holding device 100 has a housing 10 and a holder 20 movably provided in the housing 10. The housing 10 has a top wall 11, a bottom wall 12, left and right side walls 13 and 14, and a rear wall 15, and is generally formed in a box shape. The housing 10 defines a generally box-shaped storage space SP therein via an opening 16 on the front side, and the holder 20 is stored in the storage space SP.

[0011] As shown in FIG. 1A, the holder 20 has a pair of left and right storage sections 21. The left and right storage sections 21 have the same configuration. The storage section 21 has a recess 21a whose front, rear, left and right side surfaces and bottom surface are closed and whose top surface is open. The left and right side walls of each recess 21a are formed by the left and right side walls 22, 23 of the holder 20 and a partition wall 24 between the left and right side walls 22, 23. The recess 21a is formed in a generally rectangular shape in a plan view corresponding to the external shape of the battery 200, and the bottom of the battery 200 is fitted into the recess 21a, thereby holding the battery 200.

[0012] The battery 200 is a portable battery weighing, for example, about 10 kg, and has a handle 201 on its upper surface. The battery 200 may be lighter or heavier than 10 kg. The battery 200 has a generally rectangular parallelepiped shape. The battery 200 may have other shapes, such as a flat shape in which the length in the front-rear direction is shorter than the length in the left-right direction. The battery 200 is, for example, a lithium-ion battery, and can be used for various purposes. As one example, it can be used as a power source for a traveling motor mounted on a two-wheeled or four-wheeled electric vehicle.

[0013] In Fig. 1A, the storage portion 21 of the holder 20 protrudes forward from the housing 10, and the entire holder is tilted. Hereinafter, such a position or posture of the storage portion 21 will be referred to as the tilted position or posture. In Fig. 1B, the storage portion 21 is stored in the housing 10. Hereinafter, such a position or posture of the storage portion 21 will be referred to as the stored position or posture. In the stored posture, the storage portion 21 stands upright within the housing 10. The storage ratio of the holder 20 to the housing 10 in the stored position is greater than the storage ratio in the tilted position.

[0014] When the holder 20 (accommodating section 21) is in the inclined position, the accommodating section 21 is inclined forward, and the upper surface of the accommodating section 21 is exposed from the housing 10. While gripping the handle 201 of the battery 200, the user inserts the battery 200 into the recess 21a from above the accommodating section 21, as shown by the arrow A1 in Fig. 1A. The insertion direction of the battery 200 (the direction of the arrow A1) is not vertically downward, but a direction corresponding to the inclination of the accommodating section 21, that is, a direction inclined downward and backward.

[0015] The holder 20 has a substantially plate-shaped lid 25 in front of the storage section 21. The lid 25 is provided integrally with the storage section 21 and moves integrally with the storage section 21. The lid 25 has a substantially rectangular shape so as to cover the opening 16 on the front side of the housing 10, and in the storage position shown in FIG. 1B, the opening 16 is closed by the lid 25. In this storage position, as described later, a terminal (connection portion) on the bottom surface of the battery 200 is connected to a terminal (connection portion) in the holding device, and the battery 200 is charged by power supplied from the holding device side. Note that, in the storage position, the battery 200 may be configured to supply power from the battery 200 to the holding device side. That is, the holding device 100 may be used not only for charging the battery 200 but also for discharging the battery 200.

[0016] The holder 20 is connected to the housing 10 via a connecting portion so that the accommodating portion 21 can move between an inclined position and a stored position. The configuration of the connecting portion will be described below. The connecting portions are provided between the left and right side walls 13, 14 of the housing 10 and the left and right side walls 22, 23 of the holder 20, respectively. That is, the connecting portions are provided between the inner side surfaces in the left and right direction of the side walls 13, 14 facing each other and the outer side surfaces in the left and right direction of the side walls 22, 23. The configurations of the left and right connecting portions are the same. The configuration of one of the left and right connecting portions (for example, the right side) will be described below. First, a comparative example of this embodiment will be described.

[0017] Fig. 2 is a cross-sectional view showing a schematic configuration of a holding device 100A as a comparative example of this embodiment. Fig. 2 shows center-of-gravity positions G1 and G2 of the battery 200 when the holder 20 (accommodating section 21) is in the retracted position and in the inclined position, respectively. In the example of Fig. 2, the bottom of the holder 20 is supported by the side wall 14 of the housing 10 via a rotation shaft 210 extending in the left-right direction so as to be rotatable in the front-rear direction. Therefore, the height of the center-of-gravity position G1 (axis line CL1) and the height of the center-of-gravity position G2 (axis line CL2) are different from each other.

[0018] As a result, when the holder 20 is moved between the stored position and the inclined position, the gravity of the battery 200 may cause an impact on the holder 20 or may hinder the movement of the holder 20. Alternatively, the gravity of the battery 200 may cause the moving speed of the holder 20 to be too fast or too slow. For this reason, the operability when moving the holder 20 (the operability for opening and closing the lid 25), i.e., the opening and closing force, varies depending on the presence or absence of the battery 200, and the ease of attaching and detaching the battery 200 to and from the holding device 100 is impaired.

[0019] 2, in order to prevent the rear end corner of the holder 20 from contacting the rear wall 15 of the housing 10 when the accommodation portion 21 is moved from the stored position to the inclined position, it is necessary to provide a gap CL between the rear wall 26 of the holder 20 and the rear wall 15 of the housing 10. This causes the housing 10 to become larger in the front-rear direction. Therefore, in order to improve the attachment and detachment of the battery 200 and to prevent the housing 10 from becoming larger, the present embodiment configures the coupling portion as follows.

[0020] FIG. 3 is a cross-sectional view showing a schematic configuration of a main part of the holding device 100 according to the first embodiment of the present invention. For convenience, hatching showing a cross-sectional shape is omitted in FIG. 3. As shown in FIG. 3, the holding device 100 has a pair of front and rear connecting parts, that is, a first connecting part 30 provided on the rear side and a second connecting part 40 provided on the front side. FIG. 3 shows a virtual line L1 passing through the positions of the centers of gravity G1 and G2 of the battery 200. The virtual line L1 extends horizontally (forward and backward) in the storage position, and an axis L2 perpendicular to the virtual line L1 is the insertion and removal direction of the battery 200. The heights of the positions of the centers of gravity G1 and G2 indicated by the axis CL0 are the same.

[0021] 3, the first connecting portion 30 has a first link 31 formed to be elongated. The first link 31 extends in the up-down direction in the storage position, and one end (upper end) 31a in the longitudinal direction is supported by a link support portion 14a provided at the rear of the side wall 14 of the housing 10 so as to be rotatable about a rotation shaft 32 extending in the left-right direction as a fulcrum. The other end 31b in the longitudinal direction of the first link 31 is supported by a link support portion 23a provided at the rear of the side wall 23 of the holder 20 so as to be rotatable about a rotation shaft 33 extending in the left-right direction as a fulcrum. In the storage position, the link support portion 23a is located on the axis CL0, and the link support portion 14a is located above the link support portion 23a.

[0022] The second connecting portion 40 has a second link 41 formed to be elongated. The second link 41 extends in the up-down direction in the storage position, and one end (lower end) 41a in the longitudinal direction is supported by a link support portion 14b provided in the front portion of the side wall 14 of the housing 10 so as to be rotatable about a rotation shaft 42 extending in the left-right direction as a fulcrum. The other end 41b in the longitudinal direction of the second link 41 is supported by a link support portion 23b provided in the front portion of the side wall 23 of the holder 20 so as to be rotatable about a rotation shaft 43 extending in the left-right direction as a fulcrum. In the storage position, the link support portion 23b is located on the axis CL0, and the link support portion 14b is located below the link support portion 23b.

[0023] Fig. 4A is a diagram showing the operation of the connecting parts 30, 40 in the storage position and the tilted position of the housing part 21 of the holder 20, and Fig. 4B is a diagram showing the connecting parts 30, 40 in each position superimposed on each other. Note that in Fig. 4B, the connecting parts 30, 40 (first link 31, second link 41) in the storage position are shown by solid lines, and the connecting parts 30, 40 in the tilted position are shown by dotted lines.

[0024] 3, 4A, and 4B, when the storage section 21 moves from the stored position to the inclined position together with the holder 20, the first link 31 rotates forward and upward about the pivot shaft 32, and the second link 41 rotates forward and downward about the pivot shaft 42. As a result, the battery 200 (imaginary line L1) and the storage section 21 protrude forward beyond the opening 16 of the housing 10, and the upper side thereof tilts forward. At this time, as shown in FIG. 4A, the rotation of the first link 31 is restricted by a stopper 35 (restriction section) extending from the inner surface of the side wall 14 of the housing 10 toward the side wall 23 of the holder 20.

[0025] This allows the user to insert or remove the battery 200 into or from the storage section 21 along the axis L2 perpendicular to the imaginary line L1 without interfering with the upper wall 11 (FIG. 3) of the housing 10. That is, the battery 200 can be inserted or removed from the storage section 21. The stopper 35 may extend from the outer surface of the side wall 23 of the holder 20 toward the side wall 14 of the housing 10. As shown in FIG. 4A, in the storage position, the axis L2 and the vertical line L0 in the gravity direction coincide with each other. In addition, as long as the angle θ between the axis L2 and the vertical line L0 in the tilted position is larger than the angle between the axis L2 and the vertical line L0 in the storage position, the axis L2 and the vertical line L0 do not have to coincide with each other in the storage position. For example, the battery 200 may be stored tilted forward or backward.

[0026] The center of gravity position G2 of the battery 200 when the storage section 21 is in the inclined position can be adjusted by appropriately setting the positions of the link supports 14a, 14b, 23a, and 23b shown in Fig. 3. That is, since the connecting sections 30 and 40 have a link structure that does not have a fixed rotation axis of the holder 20 (for example, the rotation axis 210 in Fig. 2), the center of gravity position G2 of the battery 200 after the storage section 21 moves from the stored position to the inclined position can be easily adjusted by changing the link setting.

[0027] As shown in FIG. 3, FIG. 4A, and FIG. 4B, in this embodiment, the positions of the link supports 14a, 14b, 23a, and 23b or the positions of the pivot shafts 32, 33, 42, and 43 are set so that the height of the center of gravity G2 is equal to the height of the center of gravity G1, and the length of the links 31 and 41 is set accordingly. As a result, the height of the center of gravity G1 of the battery 200 in the storage position and the height of the center of gravity G2 of the battery 200 in the inclined position are equal. Therefore, when the storage section 21 is moved between the storage position and the inclined position with the battery 200 held in the storage section 21, it is possible to suppress deterioration of the opening and closing operability of the holder 20 due to the influence of the gravity of the battery 200. As a result, the battery 200 can be easily attached to and detached from the holding device 100.

[0028] In addition, in this embodiment, since the connecting portions 30, 40 have a link structure, there is no need to provide a gap CL (FIG. 2) between the rear wall 26 of the holder 20 and the rear wall 15 of the housing 10, as shown in FIG. 3. This makes it possible to prevent the housing 10 from becoming large in the front-rear direction, and allows the entire device to be configured compactly.

[0029] There are various link structures other than those described above that set the height of the center of gravity position G1 of the battery 200 in the stored position and the height of the center of gravity position G2 of the battery 200 in the inclined position equal to each other. Below, several examples will be described as modified examples of Figures 4A and 4B, focusing mainly on the differences from Figures 4A and 4B.

[0030] 5A and 5B show an example in which the second connecting portion 40 is configured by a plurality of links. The configuration of the first connecting portion 30 is the same as that of FIGS. 4A and 4B. As shown in FIGS. 5A and 5B, the second connecting portion 40 has a plurality of links 411 to 413 each formed to be elongated. The links 412 and 413 are formed to have the same length. The link 411 is formed to be longer than the links 412 and 413. The link 411 may be formed to be shorter than the links 412 and 413, or may be formed to be the same length as the links 412 and 413.

[0031] One end of the link 411 is supported by the link support portion 23b on the holder side so as to be rotatable about the pivot shaft 43. The link 411 extends obliquely backward and downward from the pivot shaft 43, and one end of a pair of front and rear links 412, 413 is connected to the other end so as to be rotatable about pivot shafts 44, 45 extending in the left-right direction. The links 412, 413 extend in the up-down direction in the storage position, and the other end (lower end) is supported by the link support portions 14c, 14d provided on the side wall 14 of the housing 10 so as to be rotatable about pivot shafts 46, 47 extending in the left-right direction. The distance between the link support portions 14c, 14d is equal to the distance between the pivot shafts 44, 45. Therefore, the links 412, 413 form a parallel link.

[0032] 5A and 5B, when the housing 21 moves from the storage position to the inclined position, the link 411 moves forward and downward as a whole while its rotational posture is restricted by the parallel links 412 and 413. This causes the axis L2 perpendicular to the virtual line L1 to incline forward, allowing the battery 200 to be inserted or removed along the axis L2. At this time, the heights of the center-of-gravity positions G1 and G2 of the battery 200 in the storage position and the inclined position are equal to each other, so that the holder 20 can be easily operated between the storage position and the inclined position.

[0033] In Fig. 5A and Fig. 5B, the link support 14c on the front side of the housing 10 is located behind the link support 14b on the front side of the housing 10 in Fig. 4A and Fig. 4B. The housing 10 cannot be provided behind the link support 14b and 14c, and the position of the front end of the housing 10 is determined by the positions of the link support 14b and 14c. In Fig. 5A and Fig. 5B, the link 411 moves forward as a whole in the inclined position. As a result, in the example of Fig. 5A and Fig. 5B, the storage section 21 can be protruded further forward from the housing 10 in the inclined position than in the example of Fig. 4A and Fig. 4B. As a result, the insertion and removal of the battery 200 becomes easier. Note that instead of forming the second connecting part 40 by the link 411 and a pair of links 412 and 413 connected to the link 411, the second connecting part 40 may be formed by the link 411 and a single link (for example, the link 413) connected to the link 411.

[0034] 6A and 6B show an example in which both the first connecting portion 30 and the second connecting portion 40 support the holder 20 from the upper portion of the housing 10. As shown in Fig. 6A and 6B, one end of the second link 41 is supported by the link support portion 14b on the housing side so as to be rotatable about a rotation shaft 42. In the stored position, the second link 41 extends obliquely backward and downward from the rotation shaft 42, and the other end of the second link 41 is supported by the link support portion 23b on the holder side so as to be rotatable about a rotation shaft 43.

[0035] In the example of Fig. 6A and Fig. 6B, the link support 14b is provided above the link support 23b. Therefore, the second link 41 is subjected to a tensile force due to the weight of the battery 200 and the holder 20, as in the case of the first link 31. When a compressive force acts on the links 31 and 41, in order to prevent buckling, it is necessary to configure the links 31 and 41 to have a high strength by increasing the plate thickness, providing ribs, or using a high-strength material. In this regard, in the example of Fig. 6A and Fig. 6B, since a tensile force acts on the second link 41, the second link 41 can be configured to be thinner than that of Fig. 4A and Fig. 4B, for example, and the second connecting portion 40 can be easily provided between the side wall 14 of the housing 10 and the side wall 23 of the holder 20.

[0036] 7A and 7B show an example in which the second connecting portion 40 is formed of a plurality of links 411-413 and is supported by link support portions 14c and 14d provided above the axis line CL0. That is, this is an example in which a part of the configuration of FIG. 5A and FIG. 5B is combined with a part of the configuration of FIG. 6A and FIG. 6B. In addition, in the inclined position, the link 411 is positioned overlapping the imaginary line L1. In FIG. 7A and FIG. 7B, the amount of protrusion of the accommodating portion 21 from the housing 10 in the inclined position can be increased. In addition, since a tensile force acts on the links 411 and 412, the links 411 and 412 can be configured to be thinner than those in FIG. 5A and FIG. 5B. As for the link 413, a tensile force acts on it in the example of FIG. 5A and FIG. 5B, and a compressive force acts on it in the example of FIG. 7A and FIG. 7B. 7A and 7B, a stopper 35 is provided in front of the link 412, and the rotation of the link 412 is restricted by the stopper 35. In FIG.

[0037] 8A and 8B show an example in which the first link 31 and the second link 41 are provided below the housing 10 and the holder 20. The imaginary line L1 is an imaginary line that passes through the center of gravity positions G1 and G2 of the battery 200 and also passes through the holder-side rotation shaft 33 of the first link 31 and the holder-side rotation shaft 43 of the second link 41. In FIG. 8A and FIG. 8B, the center of gravity positions G1 and G2 and the rotation shafts 33 and 43 are located on the same straight line (imaginary line L1), but either one of the rotation shafts 33 and 43 may not be on the same straight line. That is, the rotation shaft 43 may not be on the straight line connecting the center of gravity positions G1 and G2 and the rotation shaft 33, or the rotation shaft 33 may not be on the straight line connecting the center of gravity positions G1 and G2 and the rotation shaft 43.

[0038] As shown in Figs. 8A and 8B, the first link 31 is formed shorter than the second link 41. In the storage position, the holder-side link support 23a of the first link 31 is located lower and rearward than the housing-side link support 14a. The housing-side link support 14b of the second link 41 is located forward of the link support 14a. The holder-side link support 23b of the second link 41 is located above and rearward of the link support 14b, and above the link support 14a. In Fig. 8A, the stopper 35 is provided on the movement trajectory of the second link 41, not on the movement trajectory of the first link 31.

[0039] In Fig. 8A and Fig. 8B, when the storage section 21 moves from the stored position to the tilted position, the first link 31 rotates forward around the pivot shaft 32, and the second link 41 rotates forward around the pivot shaft 42. At this time, the rotation angle of the short first link 31 is larger than the rotation angle of the long second link 41. This allows the storage section 21 to be tilted forward significantly while making the heights of the center of gravity positions G1 and G2 equal to each other, and the angle θ between the vertical line L0 and the axis line L2 to be increased. In Fig. 8A and Fig. 8B, the second connecting section 40 is formed by a single link 41, so that the number of parts is smaller than that in Fig. 5A and Fig. 5B, and the configuration is easier. Furthermore, the position of the front link support section 14b is located further rearward than that in Fig. 4A and Fig. 4B, so that the protrusion amount of the storage section 21 in the tilted position can be increased.

[0040] The first connecting portion 30 and the second connecting portion 40 may be configured in a manner other than that described above. For example, the first connecting portion 30 and the second connecting portion 40 in Fig. 4A and Fig. 4B may be upside down, and the first link 31 may be provided below the axis line CL0 and the second link 41 may be provided above the axis line CL0. The first connecting portion 30 and the second connecting portion 40 in Fig. 6A, Fig. 6B and Fig. 7A and Fig. 7B may be configured upside down. The first connecting portion 30 and the second connecting portion 40 in Fig. 8A and Fig. 8B may be configured upside down.

[0041] The connection operation of the terminals provided on the bottom surface of the battery 200 will be described using the structure of FIG. 4A and FIG. 4B as an example. FIG. 9 is a diagram that shows an example of the connection operation of the terminals. The terminals are attached to and detached from the battery 200 via the attachment / detachment mechanism 50 in conjunction with the movement of the housing part 21 from the storage position to the inclined position. More specifically, a concave receptacle 200a is provided on the front side and in the center in the left-right direction on the bottom surface of the battery 200, and the plug 56a moves from below to above the receptacle 200a, and is fitted into the receptacle 200a, so that the contacts of the terminals are connected to each other. In FIG. 9, for convenience, the attachment / detachment mechanism 50 and the connecting parts 30 and 40 of FIG. 3 are each shown by a solid line. In particular, the attachment / detachment mechanism 50 is shown by a thick line.

[0042] As shown in FIG. 9, the first link 31 has an extension portion 31c extending from the pivot shaft 33, and is configured to be bent as a whole. The attachment / detachment mechanism 50 has a plurality of elongated links 51-53 arranged between the side wall 14 of the housing 10 and the side wall 23 of the holder 20, that is, a horizontal link 51, a vertical link 52, and a connecting link 53. The horizontal link 51 is arranged above the center positions G1 and G2 of the gravity of the battery 200, and extends in the approximately front-rear direction in the storage position. The central portion of the horizontal link 51 in the front-rear direction is supported by the link support portion 29 provided on the side wall 23 of the holder 20 so as to be rotatable about a pivot shaft 54 ​​extending in the left-right direction as a fulcrum. The front end of the horizontal link 51 is connected to one end of the vertical link 52 so as to be rotatable about a pivot shaft 55 extending in the left-right direction as a fulcrum.

[0043] The vertical link 52 extends in the up-down direction, and a plate 56 is fixed to its lower end. The plate 56 extends in the left-right direction along the bottom surface of the recess 21a of the holder 20, and a plug 56a is protruding from the upper surface of the plate 56 at a position corresponding to the receptacle 200a of the battery 200. Preferably, the vertical links 52 are provided on the left and right sides of the storage section 21, and both left and right ends of the plate 56 are supported by the left and right vertical links 52. The rear end of the horizontal link 51 is connected to one end of the connecting link 53 so as to be rotatable around a rotation shaft 57 extending in the left-right direction. The connecting link 53 extends in the up-down direction, and the extension portion 31c of the first link 31 is connected to its lower end so as to be rotatable around a rotation shaft 58 extending in the left-right direction.

[0044] The attachment / detachment mechanism 50 operates as follows. In the storage position shown in FIG. 9, the first link 31 extends in the vertical direction, and the pivot 58 is located at the lower end of the first link 31 (extension 31c). As a result, the connecting link 53 is pulled downward, the horizontal link 51 assumes a substantially horizontal position with the pivot 54 as a fulcrum, and the vertical link 52 is pulled upward via the pivot 55. As a result, the plate 56 moves upward, and the plug 56a fits into the receptacle 200a on the bottom surface of the battery 200. This brings the contact points of the terminal of the battery 200 and the terminal on the holding device into contact with each other, allowing charging of the battery 200. The position of the plug 56a in this state is called the connection position.

[0045] When removing the battery 200 after charging, the user moves the storage section 21 of the holder 20 to the inclined position. At this time, the first link 31 rotates upward about the pivot 32, and the connecting link 53 is pushed upward via the extension 31c. This causes the horizontal link 51 to rotate about the pivot 54, and the vertical link 52 is pushed downward. As a result, the plate 56 moves below the bottom surface of the battery 200, and the plug 56a is released from the receptacle 200a. The position of the plug 56a in this state is called the separated position.

[0046] In this way, in conjunction with the movement of accommodating section 21 from the stored position to the inclined position, plug 56a moves from the connected position to the separated position via attachment / detachment mechanism 50. Therefore, it is not necessary to perform an operation of fitting plug 56a to and detaching it from receptacle 200a separately from the operation of holder 20, and battery 200 can be easily charged. Furthermore, when battery 200 is inserted or removed from recess 21a of accommodating section 21 in the inclined position, the plug is retracted below the bottom surface of recess 21a, so that even if an impact is applied to holder 20 due to the weight of battery 200, damage to plug 56a and the terminals of receptacle 200a can be prevented.

[0047] According to this embodiment, the following advantageous effects can be obtained. (1) The holding device 100 includes a housing 10, a holder 20 provided movably relative to the housing 10 and having a storage section 21 for holding a battery 200, and connecting sections 30, 40 for connecting the housing 10 and the holder 20 such that the storage section 21 can move between a storage position where the battery 200 is stored and an inclined position where the battery 200 is attached and detached (FIGS. 1A and 3). The connecting sections 30, 40 connect the housing 10 and the holder 20 such that the height (axis line CL0) of the center of gravity position G1 of the battery 200 held by the storage section 21 located at the storage position coincides with the height (axis line CL0) of the center of gravity position G2 of the battery 200 held by the storage section 21 located at the inclined position (FIG. 3).

[0048] This suppresses vertical changes in the center of gravity positions G1, G2 that accompany the movement of the storage section 21 while the battery 200 is held, and prevents the movement of the storage section 21 from being hindered by the weight of the battery 200. As a result, the storage section 21 can be moved smoothly together with the holder 20, and the battery 200 can be easily attached and detached.

[0049] (2) The connecting portions 30, 40 have a first link 31 having one end 31a and the other end 31b connected to the housing 10 and the holder 20, respectively, and a second link 41 having one end 41a and the other end 41b connected to the housing 10 and the holder 20, respectively, at positions different from those of the first link 31 (FIG. 3). This makes it possible, with a simple configuration, to match the height of the center of gravity position G1 of the battery 200 held by the accommodating portion 21 in the stored position with the height of the center of gravity position G2 of the battery 200 held by the accommodating portion 21 in the inclined position.

[0050] (3) The housing 10 has link supports 14a, 14b to which one end 31a of the first link 31 and one end 41a of the second link 41 are respectively rotatably connected (FIG. 3). The holder 20 has link supports 23a, 23b to which the other end 31b of the first link 31 and the other end 41b of the second link 41 are respectively rotatably connected (FIG. 3). The distance between the link supports 14a, 23a corresponds to the length from one end 31a to the other end 31b of the first link 31, and the distance between the link supports 14b, 23b corresponds to the length from one end 41a to the other end 41b of the second link 41 (FIG. 3). Although the center of gravity positions G1 and G2 of the battery 200 change depending on the positions at which the link supports 14a, 14b, 23a, and 23b are provided, in this embodiment, the link supports 14a, 14b, 23a, and 23b are provided so that the heights of the center of gravity positions G1 and G2 match. This makes it possible to match the heights of the center of gravity positions G1 and G2 with a simple configuration.

[0051] (4) The first link 31 is provided so that the pivot shaft 32 at one end 31a is located higher than the pivot shaft 33 at the other end 31b (FIG. 3). The second link 41 is provided so that the pivot shaft 43 at the other end 41b is located higher than the pivot shaft 42 at one end 41a (FIG. 3). This makes it easy to achieve a configuration in which the heights of the center of gravity positions G1 and G2 are the same.

[0052] (5) The first link 31 may be configured so that the pivot shaft 32 at one end 31a is located higher than the pivot shaft 33 at the other end 31b, and the second link 41 may be configured so that the pivot shaft 42 at one end 41a is located higher than the pivot shaft 43 at the other end 41b (FIG. 6A). This allows a tensile force due to the weight of the battery 200 to act on the first link 31 and the second link 41. This allows the plate thickness of the links 31, 41 to be thinner than when a compressive force is applied, and the links 31, 41 can be easily disposed between the side walls 14, 23.

[0053] (6) The second connecting portion 40 can also be configured to have a link 411 provided with a pivot shaft 43 on the holder side, and links 412, 413 pivotally connected to the link 411 and provided with pivot shafts 46, 47 on the housing side (FIGS. 5A and 7A). This can increase the amount of protrusion of the accommodating portion 21 of the holder 20 from the housing 10 in the inclined position, making it easier to insert and remove the battery 200.

[0054] (7) In this case, a pair of links 412, 413 are rotatably connected to the link 411 (FIGS. 5A and 7A). This makes it possible to easily regulate the posture of the link 411 from the stored position to the inclined position.

[0055] (8) Furthermore, the pair of links 412, 413 are configured as parallel links that are parallel to each other (FIGS. 5A and 7A). This makes it possible to optimally set the position and posture of the link 411 during movement via the links 412, 413.

[0056] (9) The holding device 100 further includes a stopper 35 provided on the movement path of the first link 31 so as to restrict the movement (rotation) of the first link 31 (FIG. 4A). This restricts the amount of movement of the first link 31, and the storage section 21 can be easily held in the inclined position when inserting and removing the battery 200. The stopper 35 may be provided so as to restrict the amount of movement of the second link 41 (FIG. 8A).

[0057] (10) The holder 20 is provided so as to be receivable in the housing 10, and is provided so as to be movable with respect to the housing 10 such that the accommodation ratio of the holder 20 to the housing 10 when the accommodation portion 21 is located at the storage position is greater than the accommodation ratio of the holder 20 to the housing 10 when the accommodation portion 21 is located at the inclined position (FIGS. 1A, 1B, and 3). As a result, the holder 20 is largely accommodated within the housing 10 at the storage position. This reduces the amount of protrusion of the holder 20 from the housing 10, and the entire device can be constructed without any irregularities.

[0058] (11) The connecting parts 30, 40 connect the holder 20 to the housing 10 so that the storage part 21 protrudes outward from the housing 10 when the storage part 21 is in the inclined position further than when the storage part 21 is in the stored position (FIG. 3). This allows the holder 20 to protrude when the user attaches or detaches the battery 200, but the holder 20 is stored otherwise, which is excellent from the viewpoint of crime prevention.

[0059] (12) Battery 200 is removably mounted in housing 21 along axis L2 perpendicular to a reference line defined by housing 21, i.e., imaginary line L1 (FIG. 3). Housing 21 is disposed so that the angle θ of axis L2 with respect to vertical line L0 is larger when housing 21 is in the inclined position than when housing 21 is in the retracted position (FIG. 4A). This allows battery 200 to be inserted and removed without interfering with housing 10 when in the inclined position.

[0060] (13) The storage section 21 has the recess 21a that holds the battery 200 so that the battery 200 can be inserted and removed along the axis L2 ( FIG. 3 ). This makes it easy to insert and remove the battery 200 into and from the storage section 21.

[0061] (14) The housing 10 has an opening 16 that houses the storage portion 21 (FIG. 1A). The holder 20 has a lid 25 that closes the opening 16 when the storage portion 21 is in the storage position and opens the opening 16 when the storage portion 21 is in the inclined position (FIGS. 1A, 1B, and 3). This allows the battery 200 to be stored in a sealed space in the storage position, and provides good protection for the electrical components.

[0062] (15) When the storage unit 21 is in the retracted position, the rear wall 26 of the storage unit 21 is disposed adjacent to the rear wall 15 inside the housing 10 (FIG. 3). This allows the housing 10 to be made smaller in the front-to-rear direction, and the entire device can be made compact.

[0063] (16) The holding device 100 further includes a plug 56a provided so as to be releasable from a terminal portion of the battery 200, i.e., a receptacle 200a on the bottom surface of the battery 200, and an attachment / detachment mechanism 50 configured to move the plug 56a from a connection position connected to the receptacle 200a of the battery 200 to a separated position separated from the receptacle 200a in conjunction with the movement of the accommodation portion 21 from the retracted position to the inclined position (FIG. 9). This eliminates the need to perform an operation for connecting the terminals of the battery 200 separately from the operation of the holder 20 for moving the accommodation portion 21, making it easy to charge the battery 200.

[0064] -Second embodiment- A second embodiment of the present invention will be described with reference to Figures 10A and 10B. Differences from the first embodiment will be mainly described below. The second embodiment differs from the first embodiment in the configuration of the connecting parts. That is, in the first embodiment, the connecting parts 30, 40 are configured by a link structure, but in the second embodiment, the connecting parts are configured by grooves and protrusions.

[0065] FIG. 10A is a diagram showing the operation of the connecting part 60 in the retracted position and the tilted position of the accommodation part 21 of the holder 20 constituting the holding device 100 according to the second embodiment, and FIG. 10B is a diagram showing the connecting part 60 in each position superimposed. Note that FIG. 10A shows the inner surfaces of the left and right side walls 13, 14 of the housing 10. As shown in FIG. 10A and FIG. 10B, a pair of upper and lower grooves 17, 18 are provided on the inner surfaces of the left and right side walls 13, 14 of the housing 10. The upper groove 17 extends in the front-rear direction for a predetermined length along the axis CL0. The lower groove 18 extends in the up-down direction for a predetermined length behind the groove 17.

[0066] A pair of upper and lower projections 27, 28 projecting outward in the left-right direction from the outer surfaces of the left and right side walls 22, 23 of the holder 20 are engaged with the grooves 17, 18, respectively. The position of the projection 27 is the same as the center of gravity positions G1, G2 of the battery 200 held by the storage section 21 (FIG. 1A). For convenience, the projections 27, 28 are shown connected by a virtual line L1. The projections 27, 28 are movable along the grooves 17, 18, respectively, and the projections 27, 28 and the grooves 17, 18 form a connecting section 60. The combination of the upper groove 17 and projection 27 may be called a first connecting section 61, and the combination of the lower groove 18 and projection 28 may be called a second connecting section 62.

[0067] In the stored position where the accommodating portion 21 is stored in the housing 10, the protrusion 27 is located at the rear end of the groove 17, and the protrusion 28 is located at the lower end of the groove 18. On the other hand, in the tilted position where the accommodating portion 21 protrudes from the housing 10, the protrusion 27 is located at the front end of the groove 17, and the protrusion 28 is located at the upper end of the groove 18. In the stored position, one of the protrusions 27 and 28 abuts against the end of the groove 17 and 18, and in the tilted position, one of the protrusions 27 and 28 abuts against the end of the groove 17 and 18. This limits the movement of the holder 20 relative to the housing 10. At this time, the ends of the grooves 17 and 18 function as stoppers. Therefore, there is no need to provide a stopper separately.

[0068] In the second embodiment, the projections 27, 28 engage with the grooves 17, 18 to restrict the positions of the projections 27, 28 while the storage section 21 of the holder 20 moves from the storage position to the tilted position. More specifically, the projection 27 moves horizontally along the axis CL0. This makes it possible to make the height of the center of gravity G1 of the battery 200 in the storage position equal to the height of the center of gravity G2 in the tilted position. As a result, the weight of the battery 200 is prevented from interfering with the movement of the storage section 21, and the battery 200 can be easily attached and detached.

[0069] 10A and 10B, the first groove and the second groove are provided on the housing 10, and the first protrusion and the second protrusion are provided on the holder 20. However, the arrangement of the grooves and protrusions is not limited thereto, and the first groove and the second groove may be provided on the holder 20, and the first protrusion and the second protrusion may be provided on the housing 10. The first groove and the second protrusion may be provided on the housing, and the second groove and the first protrusion may be provided on the holder.

[0070] The second embodiment can achieve the following advantageous effects different from those of the first embodiment. (1) The connecting portion 60 has a first connecting portion 61 and a second connecting portion 62 provided at a predetermined distance from each other (FIG. 10A). The first connecting portion 61 has a protrusion 27 provided on the holder 20 and a groove 17 provided on the housing 10 so that the protrusion 27 can engage with the protrusion, and the second connecting portion 62 has a protrusion 28 provided on the holder 20 and a groove 18 provided on the housing so that the protrusion 28 can engage with the protrusion (FIG. 10A). This allows for an inexpensive configuration that suppresses an increase in the number of parts, and makes it possible to equalize the heights of the center of gravity positions G1, G2 of the battery 200 when the storage portion 21 moves from the stored position to the inclined position.

[0071] (2) The groove 17 of the first connecting part 61 extends in the front-rear direction so that the protrusion 27 can move linearly along the groove 17, and the groove 18 of the second connecting part 62 extends in the up-down direction so that the protrusion 28 can move linearly along the groove 18 ( FIG. 10A ). By engaging the protrusions 27, 28 with the pair of linear grooves 17, 18 in this manner, the attitude of the storage part 21 in the inclined position can be easily adjusted with a simple configuration.

[0072] (3) Groove 17 and groove 18 extend in different directions (FIG. 10A). By providing a pair of grooves 17, 18 extending in different directions in this manner, storage section 21 can be easily tilted as holder 20 moves, making it easier to insert and remove battery 200.

[0073] (4) Groove 17 extends horizontally (forward and backward) (FIG. 10A). This allows the height of the center of gravity of battery 200 to be kept constant as the storage section moves. In addition, engagement between groove 18 and protrusion 28 allows storage section 21 to be gradually tilted as storage section 21 moves from the retracted position to the tilted position.

[0074] Other embodiments or modifications will be described below. In the above embodiment, the battery 200 is attached and detached when the storage section 21 is in the inclined position, but the battery 200 may be attached and detached when the storage section 21 is in a position other than the inclined position. FIG. 11 is a diagram showing one example. In FIG. 11, similar to FIG. 3, the storage section 21 is supported so as to be movable integrally with the holder 20 via the first connecting section 30 (first link 31) and the second connecting section 40 (second link 41). However, in FIG. 11 In the embodiment, a cover portion 19 is provided on the housing 10 to cover the upper side of the storage portion 21 in the inclined position.

[0075] Therefore, when the storage section 21 is in the inclined position, it is stored in the housing 10. On the other hand, when the storage section 21 is in the upright position, the upper part of the storage section 21 is open, and in this state, the battery 200 is inserted and removed. That is, the battery 200 is inserted and removed along a vertical axis L2 perpendicular to the imaginary line L1 of the battery 200. Note that the insertion and removal direction of the battery 200 (the direction of the axis L2) is not limited to the above, and may be, for example, a horizontal direction. That is, the first position where the battery 200 is stored is not limited to the stored position, and the second position where the battery 200 is attached and detached is not limited to the inclined position.

[0076] In the above embodiment, the housing 10 as the first member and the holder 20 as the second member are connected via the connecting parts 30, 40, 60, but the configuration of the first member and the second member is not limited to the above. The holder 20 may have a plurality of storage parts 21 as a holding part in the vertical direction instead of a plurality of storage parts 21 in the horizontal direction. The holder 20 may have a single storage part 21 (holding part) instead of a plurality of storage parts 21. In the above embodiment, the holder 20 has the lid 25, but the lid part may be omitted and the holder may be stored in a state where a part of the holding part is exposed. In the above embodiment, the holding device 100 holds the battery 200, but the holding device may hold a capacitor, and the power storage device to which the present invention is applied is not limited to a power storage part such as a battery.

[0077] In the above embodiment, the storage section 21 is configured to be movable between a storage position (first position) in which the battery 200 is stored and an inclined position (second position) in which the battery 200 is attached or detached, but the first position and the second position may be positions other than those described above. In the storage position, the storage section 21 may not be entirely stored in the housing 10, but only a part of it may be stored. In the inclined position, the storage section 21 may not be entirely protruding from the housing 10, but only a part of it may be protruding.

[0078] In the above embodiment, the connecting parts 30, 40, 60 are formed by a link structure or by engagement between a groove and a protrusion, but the connecting parts may be formed in a form other than the above, as long as the height (vertical position) of the center of gravity position G1 (first center of gravity position) at the first position and the height of the center of gravity position G2 (second center of gravity position) at the second position are connected to match. In the above embodiment, the first connecting part 30 is formed by the first link 31 (first connecting member) having one end 31a (first connecting part at one end) and the other end 31b (first connecting part at the other end), and the second connecting part 40 is formed by the second link 41 (second connecting member) having one end 41a (second connecting part at one end) and the other end 41b (second connecting part at the other end), but the first connecting member and the second connecting member may be formed by something other than a link. The one-end first connecting portion or the other-end first connecting portion may be provided at an end other than the one end 31a or at an end other than the other end 31b of the first link 31. The one-end second connecting portion or the other-end second connecting portion may be provided at an end other than the one end 41a or at an end other than the other end 41b of the second link 41.

[0079] In the above embodiment, the housing 10 is provided with link support portion 14a (one end first connected portion) and link support portion 14b (one end second connected portion) to which one end 31a of the first link 31 and one end 41a of the second link 41 are respectively rotatably connected, and the holder 20 is provided with link support portion 23a (the other end first connected portion) and link support portion 23b (the other end second connected portion) to which the other end 31b of the first link 31 and the other end 41b of the second link 41 are respectively rotatably connected. However, as long as they are arranged so that the heights of the center of gravity positions are the same, the one end first connected portion, one end second connected portion, the other end first connected portion and the other end second connected portion may be arranged at positions other than those described above.

[0080] In the above embodiment (FIGS. 5A and 7A), the second connecting portion 40 (second connecting member) is constituted by a link 411 (first component member) having an end (second connecting portion at the other end) connected to the link support portion 23b on the holder side, and a pair of links 412, 413 (second component members) rotatably connected to the link 411 and having ends (second connecting portions at one end) connected to the link support portions 14c, 14d on the housing side. More specifically, the pair of links 412, 413 are provided in parallel, but the pair of second component members do not have to be parallel. The second connecting member may be constituted by the first component member and a single second component member.

[0081] In the above embodiment (FIG. 3, etc.), when the storage portion 21 moves from the storage position (first position) to the tilted position (second position), the first link 31 as the first connecting member is configured to extend from the housing 10 as the first member to the holder 20 as the second member, but instead, it may be configured to extend from the second member to the first member. Alternatively, it may be configured to extend from the first member to the second member and from the second member to the first member. In the above embodiment, the movement of the first link 31 is restricted by the stopper 35, but the configuration of the restricting portion provided on the movement trajectory of the first connecting member is not limited to the above. For example, a restricting portion may be provided on the rotation axis of the first connecting member.

[0082] In the above embodiment (FIG. 10A), the first connecting portion 61 has the protrusion 27 (first engaging portion) provided on the holder 20 and the groove 17 (first engaged portion) provided on the housing 10, and the second connecting portion 62 has the protrusion 28 (second engaging portion) provided on the holder 20 and the groove 18 (second engaged portion) provided on the housing 10, but the configurations of these engaging portions and engaged portions are not limited to those described above. For example, the engaged portion may be configured in a rail shape. In the above embodiment, the groove 17 is linearly extended in the front-rear direction (first direction), and the groove 18 is linearly extended in the up-down direction (second direction), but the first direction and the second direction may be directions other than those described above. The engaged portion may be formed in a non-linear shape.

[0083] In the above embodiment, the recess 21a provided in the storage section 21 holds the battery 200 so as to be insertable and removable along the axis L2 (reference line), but the battery 200 may be held by something other than the recess (for example, a protrusion). Instead of storing and holding the battery 200 (storage battery) in the storage section 21, a mounting section on which the storage battery is placed may be provided and the storage battery may be held by the mounting section. In the above embodiment, the storage section 21 is arranged adjacent to the front surface (wall surface) of the rear wall 15 of the housing 10 in the stored position, but it may be arranged adjacent to another wall surface inside the first member.

[0084] In the above embodiment (FIG. 9), the detachment mechanism 50 moves the plug 56a (movable connection part) provided below the holder 20 from a connection position where it is connected to the receptacle 200a (connection part) of the battery 200 to a separated position away from the connection part in conjunction with the movement of the accommodation part 21 from the retracted position to the inclined position, but the configuration of the detachment mechanism 50 as a moving mechanism is not limited to the above. An actuator may be used to move the movable connection part from the connection position to the separated position, or from the separated position to the connection position.

[0085] In addition, the connecting portion may have any configuration as long as it is configured to connect the first member and the second member so that the height of the center of gravity of the storage battery held by the holding portion located at the first position coincides with the height of the center of gravity of the storage battery held by the holding portion located at the second position, or as long as the connecting portion is configured to have a first connecting member on one end side and a first connecting portion on the other end side, which are connected to the first member and the second member, respectively, and a second connecting member on one end side and a second connecting portion on the other end side, which are connected to the first member and the second member, respectively, at a position different from the first connecting member.

[0086] In the above embodiment, the battery 200 that stores power is held by the holding section (container), but the present invention can be similarly applied to the case of holding other energy storage devices, such as a hydrogen container (portable hydrogen tank) that stores hydrogen used in a fuel cell. That is, energy storage includes not only the case of storing energy such as electric power, but also the case of storing an energy source (hydrogen for a fuel cell) for generating energy (electric power). Therefore, the portable energy storage device (energy storage device) is not limited to the portable battery (electric power storage device) described above, but may be a hydrogen tank (energy source storage device). In the above embodiment, power is transferred in a state in which the connection section of the battery 200 and the connection section of the holding device are connected, but if the energy storage device is a hydrogen tank, hydrogen may be transferred in a state in which the connection section of the hydrogen tank and the holding device are connected. In the above embodiment, the energy storage device is portable so that a person can carry it, and is attached to and detached from the holding device by human power alone, but the energy storage device may be attached to and detached from the holding device by using a machine or mechanism as an auxiliary. This makes it possible to easily attach and detach a heavy energy storage device.

[0087] The above description is merely an example, and the present invention is not limited to the above-mentioned embodiment and modifications, as long as the features of the present invention are not impaired. The above-mentioned embodiment and one or more modifications can be arbitrarily combined, and modifications can be combined with each other. [Explanation of symbols]
