[0008] (Outline of this embodiment) (1) A storage battery disclosed herein comprises an electrode, a battery case having an opening and housing the electrode, a lid portion closing the battery case, and a handle, the lid portion having a pair of side surfaces, each of the pair of side surfaces being provided with a pair of support portions, the support portion comprising an axis portion protruding from the side surfaces and a stop portion formed on the protruding end of the axis portion, the stop portion having a portion extending upward from the axis portion, the handle comprising a grip portion and a pair of arms extending from both ends of the grip portion, a through hole formed in an end of the arm portion to receive the axis portion, when the arms extend in a direction perpendicular to the opening direction of the opening, the through hole has a shape that fits the support portion, allowing the support portion to be inserted and removed from the insertion hole, and when the grip portion is lifted, the stop portion engages with the edge of the insertion hole.

[0009] With this configuration, it is possible to prevent the handle from coming off the lid when the storage battery is transported, and the handle can be easily attached to the lid.

[0010] (2) In the storage battery described above in (1), it is preferable that the retaining portion further has a portion extending downward from the shaft portion.

[0011] With this configuration, it is easy to increase the area over which the anti-slip portion engages with the edge of the insertion hole, which further prevents the handle from coming off the lid when the storage battery is transported.

[0012] (3) In the storage battery of (1) or (2) above, it is preferable that the shaft portion protrudes axially from the side surface, the arm portion has an extension portion extending from the end of the arm portion in a direction perpendicular to the axial direction, and the cover portion has a locking portion arranged in the vicinity of the support portion, and that when the arm portion extends in a direction perpendicular to the opening direction of the opening, the extension portion does not interfere with the locking portion, and when the gripping portion is lifted, the extension portion locks with the locking portion.

[0013] With this configuration, the extension portion and the locking portion are locked together, which further prevents the handle from coming off the lid portion when the storage battery is transported.

[0014] (4) In any one of the storage batteries (1) to (3) above, it is preferable that the shaft portion protrudes in the axial direction from the side surface, and the contour line of the retaining portion is curved when viewed in the axial direction.

[0015] With this configuration, it is possible to prevent the insertion hole from expanding while ensuring the area required for engagement between the retaining portion and the edge of the insertion hole, thereby preventing a decrease in strength of the end of the arm and wobbling of the arm relative to the cover.

[0016] <Embodiment 1> A first embodiment of the present disclosure will be described with reference to Figures 1 to 14. In the following description, the front-rear direction, left-right direction, and up-down direction are based on the front-rear direction, left-right direction, and up-down direction shown in Figure 1. In this specification, "perpendicular" and "parallel" do not only mean strictly perpendicular and parallel, but also include roughly perpendicular and parallel within the scope of the action and effect of this embodiment.

[0017] 1. Battery configuration The storage battery 10 is mounted on a mobile object such as a four-wheeled vehicle or a two-wheeled vehicle. The storage battery 10 in this embodiment is a lead-acid battery. As shown in Fig. 1, the storage battery 10 includes a battery case 11 having an opening 15 (see Fig. 2), a lid 20 that closes the opening 15 of the battery case 11, and a handle 30 that is rotatably supported by the lid 20. The battery case 11, the lid 20, and the handle 30 are each made of synthetic resin.

[0018] As shown in Fig. 2, the battery case 11 is box-shaped and opens upward. The opening 15 of the battery case 11 opens in the vertical direction. Five partition walls 11A are formed inside the battery case 11 at equal intervals in the left-right direction. The five partition walls 11A divide the inside of the battery case 11 into six cell chambers 12. As shown in Fig. 3, each cell chamber 12 contains a plate group 13 (an example of an electrode) and an electrolyte 14 made of dilute sulfuric acid.

[0019] The electrode plate group 13 is composed of a positive electrode plate 13A, a negative electrode plate 13B, and a separator 13C that separates the positive electrode plates 13A, 13B. Each of the electrode plates 13A, 13B is composed of a lattice body filled with an active material.

[0020] 1, the storage battery 10 is provided with a positive external terminal 10A and a negative external terminal 10B. These external terminals 10A, 10B are disposed at the right end and the left end of the upper surface of the lid portion 20, respectively.

[0021] 2. Lid structure As shown in Fig. 4, the lid 20 includes a flat plate 21, an outer peripheral wall 22 extending downward from the outer peripheral edge of the flat plate 21, and an overhang 23 overhanging upward from the flat plate 21. The flat plate 21 is thin in the vertical direction and is formed to a size capable of closing the opening 15 of the battery case 11. A lid partition wall (not shown) is formed on the back surface of the lid 20 at a position corresponding to the partition wall 11A of the battery case 11. The lid 20 is attached so as to be overlapped on the battery case 11, and is heat-welded to the battery case 11.

[0022] The protruding portion 23 is substantially T-shaped in a plan view. The protruding portion 23 includes a horizontally long portion 23A and a convex portion 23B that protrudes forward from the left-right center of the horizontally long portion 23A. The horizontally long portion 23A is long in the left-right direction and is disposed in the rear half of the lid portion 20. The convex portion 23B is disposed between the positive electrode external terminal 10A and the negative electrode external terminal 10B in the left-right direction.

[0023] A pair of support parts 25 are provided on each of a pair of side surfaces 24 (left and right surfaces) of the horizontally elongated portion 23A. The pair of support parts 25 are disposed at approximately the center of the front-rear direction of the lid portion 20. The support parts 25 are inserted into insertion holes 35 of the handle 30 to support the handle 30. When the handle 30 is supported by the support parts 25, the handle 30 is rotatable relative to the lid portion 20.

[0024] 5, the support portion 25 includes a shaft portion 25A protruding from the side surface 24, and a retaining portion 25B formed at the protruding end of the shaft portion 25A. The direction in which the shaft portion 25A protrudes from the side surface 24 is defined as the axial direction. In this embodiment, the axial direction is the left-right direction (left or right). The shaft portion 25A has a generally cylindrical shape extending in the axial direction.

[0025] The retaining portion 25B extends from the shaft portion 25A in a radial direction perpendicular to the axial direction. In this embodiment, the retaining portion 25B extends upward from the shaft portion 25A. As shown in FIG. 6, the contour line of the retaining portion 25B in the axial direction (side view) is curved. The retaining portion 25B is smoothly connected to the outer peripheral surface of the shaft portion 25A. The support portion 25 as a whole has a substantially egg shape in a side view.

[0026] As shown in Figs. 6 and 11, the support portion 25 may have a lightening hole 25C formed so as to be recessed from the protruding end surface of the support portion 25 in the axial direction.

[0027] As shown in Figs. 5 and 6, a slit 25D extending in the radial direction is provided at the protruding end of the support portion 25, and the protruding end of the support portion 25 may be divided by the slit 25D. For example, in this embodiment, the support portion 25 includes a first divided body 25E and a second divided body 25F divided by the slit 25D extending in the front-rear direction. The first divided body 25E is disposed above the second divided body 25F. The retaining portion 25B is disposed on the first divided body 25E side. With this configuration, the first divided body 25E and the second divided body 25F can be elastically deformed so as to approach each other, and the support portion 25 can be easily inserted into the insertion hole 35 of the handle 30.

[0028] As shown in Figs. 4 and 12, the engaging portions 26 are provided on both sides and the rear of the horizontally elongated portion 23A of the cover 20. The engaging portions 26 are formed so as to protrude upward from the flat plate portion 21 and to be recessed with respect to the upper surface of the horizontally elongated portion 23A. The engaging portions 26 are arranged so as to partially surround the outer periphery of the horizontally elongated portion 23A. As shown in Figs. 1 and 10, the engaging portions 26 have a shape that allows the handle 30 attached to the cover 20 to engage with them. When the handle 30 is engaged with the engaging portions 26, the arms 32 of the handle 30 are arranged to extend in the front-rear direction, and the gripping portion 31 of the handle 30 is arranged to extend in the left-right direction. In addition, the upper surface of the horizontally elongated portion 23A and the upper surface of the handle 30 are arranged at approximately the same position in the vertical direction.

[0029] 3. Handle configuration As shown in Fig. 4, the handle 30 includes a grip portion 31 and a pair of arms 32 extending from both ends of the grip portion 31. The grip portion 31 and the pair of arms 32 each have an elongated shape. Each of the pair of arms 32 includes a tip portion 33 (an example of an end portion of an arm portion) disposed on the opposite side to the connection portion with the grip portion 31. The pair of arms 32 are configured to be elastically deformable from the grip portion 31 such that the tip portions 33 of the pair of arms 32 move away from each other. The grip portion 31 is a portion that an operator grasps with his or her hands when, for example, transporting the storage battery 10.

[0030] As shown in FIG. 7, each arm 32 has a cylindrical portion 34 at its tip 33. The cylindrical portion 34 is formed by penetrating the tip 33 of the arm 32 in the direction in which the pair of arms 32 are aligned. When the handle 30 is attached to the lid 20, the direction in which the pair of arms 32 are aligned coincides with the axial direction (left-right direction). The cylindrical portion 34 has a first portion 34A and a second portion 34B that is connected to the first portion 34A in the axial direction. As shown in FIG. 11, the inner diameter of the second portion 34B is larger than the inner diameter of the first portion 34A. The inner peripheral surface of the second portion 34B is disposed radially outward from the inner peripheral surface of the first portion 34A. The first portion 34A is disposed on the side of the cylindrical portion 34 that is closer to the side surface 24 of the lid 20 in the axial direction (hereinafter referred to as the inner side in the axial direction). The second portion 34B is disposed on the side of the cylindrical portion 34 that is farther from the side surface 24 of the cover portion 20 in the axial direction (hereinafter, referred to as the outer side in the axial direction).

[0031] The first portion 34A has an insertion hole 35 that receives the shaft portion 25A of the support portion 25. The second portion 34B has a communication hole 36 that receives the protruding end portion of the support portion 25. The insertion hole 35 and the communication hole 36 are in communication with each other.

[0032] The inner circumferential surface of the first portion 34A and the inner circumferential surface of the second portion 34B are connected in a stepped manner via a retaining portion 37. The retaining portion 37 is a surface of the hole edge of the insertion hole 35 that is disposed on the outer side in the axial direction.

[0033] As shown in Fig. 4, the handle 30 of this embodiment is attached to the lid 20 with the pair of arms 32 aligned in the axial direction and extending horizontally (one example of a direction perpendicular to the opening direction of the opening). More specifically, the pair of arms 32 extend forward relative to the grip 31. Hereinafter, the position of the handle 30 when attached to the lid 20 is referred to as the attachment position. Specifically, the attachment position is the position of the handle 30 shown in Figs. 1, 4, and 10.

[0034] As shown in FIG. 14, when the handle 30 is in the mounting position, the shape of the insertion hole 35 in a side view (see FIG. 9) matches the shape of the support part 25 in a side view (see FIG. 6). In other words, the outline of the insertion hole 35 in the axial direction is substantially the same as the outline of the support part 25 in the axial direction. The two-dot chain lines in FIG. 9 and FIG. 14 indicate the shape of the shaft part 25A inserted into the insertion hole 35 in a side view. Since the shape of the insertion hole 35 in a side view matches the shape of the support part 25 in a side view, when the handle 30 is in the mounting position, the insertion of the support part 25 into the insertion hole 35 is permitted (see FIG. 11). Similarly, when the handle 30 is attached to the cover part 20 and the handle 30 is in the mounting position, the support part 25 can be removed from the insertion hole 35.

[0035] In a state where the pair of arms 32 are rotated from the attached posture around a virtual axis extending in the axial direction, the shape of the insertion hole 35 in a side view does not match the shape of the support part 25 in a side view. For this reason, the protruding end part (retaining part 25B) of the support part 25 hits the hole edge part of the insertion hole 35, so that the insertion of the support part 25 into the insertion hole 35 is not allowed.

[0036] When the pair of arms 32 are rotated from the attached position about the shaft 25A with the shaft 25A inserted through the insertion hole 35, the retaining portion 25B and the retaining portion 37 are disposed opposite to each other in the axial direction. Thus, the retaining portion 25B and the retaining portion 37 are engaged with each other in the axial direction, thereby preventing the shaft 25A from coming off the insertion hole 35. For example, as shown in FIG. 13, the retaining portion 25B is engaged with the retaining portion 37 when the grip portion 31 is raised.

[0037] In this embodiment, the handle 30 is rotatable about the shaft portion 25A between a position where it engages with the engaging portion 26 (see FIG. 10) and a position where it interferes with the external terminals 10A, 10B.

[0038] When the retaining portion 25B is configured to be elastically deformable as described above, the shape of the outer portion of the insertion hole 35 through which the shaft portion 25A is inserted (see FIG. 9) in a side view may be set to be slightly smaller than the shape of the retaining portion 25B in a side view (see FIG. 6). According to this configuration, the retaining portion 25B (first divided body 25E) slides against the hole edge of the insertion hole 35 and elastically deforms, so that the shaft portion 25A can be inserted into the insertion hole 35. Furthermore, after the shaft portion 25A is inserted into the insertion hole 35, the retaining portion 25B returns to its natural state, so that the retaining receiving portion 37 and the retaining portion 25B can be engaged in the axial direction. Therefore, even when the handle 30 is in the mounting position, the shaft portion 25A can be prevented from coming off the insertion hole 35 (see FIG. 11). In this case, the operator can remove the support portion 25 from the insertion hole 35 by elastically deforming the retaining portion 25B.

[0039] Furthermore, when the pair of arms 32 are rotated from the attached position around the axis 25A, the amount of elastic deformation of the first segment 25E and the second segment 25F is designed so that the support portion 25 does not come out of the insertion hole 35 even if the first segment 25E and the second segment 25F are elastically deformed.

[0040] As shown in Fig. 8, the tip 33 of the arm 32 has an opposing portion 38 disposed on the axially inner side of the hole edge of the insertion hole 35. When the pair of arms 32 are in the mounting position, the opposing portion 38 and the side surface 24 are disposed to face each other, making it possible to insert the support portion 25 into the insertion hole 35 (see Fig. 11). When the pair of arms 32 are rotated from the mounting position about a virtual axis extending in the axial direction, the protruding end of the support portion 25 abuts against the opposing portion 38, so that the support portion 25 is not allowed to be inserted into the insertion hole 35.

[0041] In this embodiment, as shown in Fig. 8, a guide portion 41 is formed on the facing portion 38. When the handle 30 is in the mounting position, the guide portion 41 is disposed on the lower portion of the facing portion 38. The guide portion 41 is recessed from the end face of the facing portion 38 outward in the axial direction and has a groove shape extending in the vertical direction. When the handle 30 is in the mounting position, the tip portion 33 of the arm portion 32 is pressed against the protruding end of the support portion 25 from above, whereby the tip portion 33 of the arm portion 32 is elastically deformed so as to open outward in the axial direction relative to the grip portion 31, and the support portion 25 is guided to the insertion hole 35 through the guide portion 41 (see Fig. 4).

[0042] 4.Effects In the above configuration, when the pair of arms 32 are in the mounting position, the insertion hole 35 has a shape that fits the support part 25, allowing the support part 25 to be inserted into and removed from the insertion hole 35. When the grip part 31 is raised, the retaining part 25B engages with the edge of the insertion hole 35. Therefore, according to this embodiment, the handle 30 can be easily attached to the lid part 20. Also, the handle 30 can be prevented from coming off the lid part 20 when the storage battery 10 is transported.

[0043] In this embodiment, the contour of the retaining portion 25B is curved when viewed in the axial direction. With this configuration, compared to a case where the retaining portion is formed in a rectangular shape, for example, it is easier to prevent the insertion hole 35 from expanding while ensuring the area required for engagement between the retaining portion 25B and the hole edge of the insertion hole 35. This makes it possible to prevent a decrease in strength of the tip portion 33 of the arm portion 32 and rattling of the arm portion 32 relative to the cover portion 20.

[0044] <Embodiment 2> A second embodiment of the present disclosure will be described with reference to Figures 15 to 18. Hereinafter, the same components as those in the first embodiment will be denoted by the same reference numerals, and duplicated descriptions may be omitted.

[0045] As shown in Fig. 15, the support part 125 of the cover part 120 according to the second embodiment includes a shaft part 25A and a retaining part 125B. The retaining part 125B has a portion extending upward from the shaft part 25A and a portion extending downward from the shaft part 25A. The contour line of the retaining part 125B in a side view is mainly arc-shaped and partially linear. The shape of the support part 125 in a side view is substantially elliptical. In another embodiment, the retaining part formed in an arc shape may have only a portion extending upward from the shaft part.

[0046] 16, the handle 130 according to the second embodiment includes an arm 132, and an insertion hole 135 is formed in a tip 133 of the arm 132. When the arm 132 is in the mounting position, the insertion hole 135 has a shape that fits the support part 125. In other words, the shape of the insertion hole 135 in a side view is substantially the same as the shape of the support part 125 in a side view.

[0047] Fig. 17 is a cross-sectional view corresponding to Fig. 11 of embodiment 1. When arm portion 132 is in the mounting position, as shown in Fig. 17, the shape of insertion hole 135 and the shape of support portion 125 match, so that support portion 125 can be inserted into and removed from insertion hole 135.

[0048] Fig. 18 is a cross-sectional view corresponding to Fig. 13 of the first embodiment. As shown in Fig. 18, when the gripping portion 31 is lifted and the arm portion 132 is rotated from the attached posture, the retaining portion 125B and the retaining receiving portion 37 are arranged to face each other in the axial direction (left-right direction). Therefore, it is possible to prevent the support portion 125 from coming off the insertion hole 135.

[0049] According to the configuration of the second embodiment, it is easier to increase the area for engagement between the retaining portion 125B and the retaining receiving portion 37, compared to the case where the retaining portion 25B is provided only above the shaft portion 25A as in the first embodiment. Therefore, it is possible to further prevent the handle 130 from coming off the cover portion 120.

[0050] <Embodiment 3> A third embodiment of the present disclosure will be described with reference to Fig. 19 to Fig. 27. Hereinafter, the same components as those in the first embodiment will be denoted by the same reference numerals, and duplicated descriptions may be omitted.

[0051] 19, the handle 230 according to the third embodiment includes an extension 250. The cover 220 according to the third embodiment has a recess 227 that receives the extension 250 when the arm 232 is rotated from the attached position.

[0052] 20 and 21, support portion 225 of cover portion 220 includes shaft portion 225A and retaining portion 25B. Shaft portion 225A has a shape in which a part of a cylinder is cut out for the convenience of forming recess 227, but it does not have to have a cut-out shape.

[0053] As shown in FIG. 21, the recess 227 is disposed so as to surround the support portion 225 from the rear of the support portion 225 to the diagonally downward front. The recess 227 is configured by a side surface 24, a locking portion 227A axially facing the side surface 24, and a bottom surface 227B disposed between the side surface 24 and the locking portion 227A. The locking portion 227A is disposed in the vicinity of the support portion 225. The bottom surface 227B faces the support portion 225 in the radial direction. The bottom surface 227B may be curved. For the convenience of molding the support portion 225, the locking portion 227A has a groove portion 227A1 recessed downward from the end surface of the locking portion 227A formed therein, but the groove portion 227A1 may not be formed.

[0054] 22, arm 232 of handle 230 includes extension 250 extending radially from tip 233 in a direction perpendicular to the axial direction. In detail, extension 250 extends forward when arm 232 is in the attached position. Extension 250 is formed on the inner portion of tip 233 in the axial direction.

[0055] 23, when the arm portion 232 is in the mounting position, the extension portion 250 is disposed in a position not axially opposed to the locking portion 227A. In this state, similar to the first embodiment, the support portion 225 is allowed to be inserted into and removed from the insertion hole 35 (see FIG. 24).

[0056] In the state where the gripping portion 31 is lifted, as shown in Fig. 25, at least a part of the extension portion 250 is disposed in a position facing the locking portion 227A in the axial direction. As shown in Fig. 26, at least a part of the extension portion 250 is located inside the recess 227. Therefore, for example, when the arm portion 232 is pulled outward in the axial direction, the extension portion 250 is locked with the locking portion 227A in the axial direction, so that the tip portion 233 can be prevented from being displaced in the axial direction. Therefore, the support portion 225 can be prevented from coming off the insertion hole 35.

[0057] In the state where the grip portion 31 is raised, as in the first embodiment, the retaining portion 25B and the retaining receiving portion 37 are engaged to prevent the support portion 225 from coming off the insertion hole 35 (see FIG. 27).

[0058] According to the configuration of the third embodiment, the extension portion 250 and the locking portion 227A are locked together, so that the handle 230 can be prevented from coming off the cover portion 220 even more.

[0059] <Other embodiments> The present disclosure is not limited to the embodiments described above and illustrated in the drawings, but is intended to include all modifications within the scope of the claims and their equivalent meanings. The technical scope of the present disclosure also includes, for example, the following embodiments.

[0060] The guide may be omitted.

[0061] The second portion of the cylindrical portion may be omitted.

[0062] Holes and slits may be omitted.

[0063] The contour line of the retaining portion when viewed in the axial direction does not have to be curved, and may be, for example, a broken line (polygonal shape). [Explanation of symbols]
