 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of a battery storage structure according to the present invention, FIG. 2 is a bottom view of the same, and FIG. 3 is a side sectional view of the same. In these drawings, the battery storage chamber 2 is formed in a concave shape on the bottom surface of the device 1 and has a substantially U-shaped cross section. The holding piece 4 is projected. Reference numeral 5 denotes a hole for removing the molding die when forming the holding piece 4. Reference numerals 7 and 8 denote through holes and support holes which are formed so as to straddle the upper surface plate 3 and the side surface plate 10.

A pair of bosses 12 are erected on a bottom surface portion 11 adjacent to the side surface plate 10, and a rectangular sliding hole 14 is provided between the bosses 12 to form a pedestal portion having a trapezoidal shape in a side view. 13 is protruding. Reference numeral 15 is a fixing bracket that is entirely formed of a thin plate, and is composed of a bottom plate 16 and a side plate 17 that are bent at a substantially right angle. The bottom plate 16 is provided with a mounting hole 18, and the side plate 17 has a small diameter. The support hole 19 and the large-diameter through hole 20 are provided, and the bent portion 21 is formed.

Reference numeral 23 is an elongated lock releasing member 23, which has an operating portion 24 projecting from the lower surface thereof, a tilted cam portion 25 standing upright from the upper surface thereof, and a spring retaining portion 26 formed at the tip thereof. ing. Numeral 27 is a torsion spring. Reference numeral 30 denotes a lock member, which includes a support dowel 31 projecting to the front and back, a spring retaining dowel 34 projecting to one side, a lock part 32 projecting to the side face plate 10 side, and an engaging part 33 projecting downward. .

Next, a method for assembling the battery housing structure having such a configuration will be described. First, the operation portion 24 of the lock releasing member 23 is fitted into the sliding hole 14 and the lock releasing member 23 is placed on the pedestal portion 13. Next, one of the support bosses 31 of the lock member 30 is fitted into the support hole 8 and the lock portion 32 is fitted into the through hole 7 at the same time to temporarily support the lock member 30 on the side plate 10 on the outer surface of the battery storage chamber 2. . Then, the other support dowel 31 of the lock member 30 is fitted into the support hole 19 of the fixing bracket 15, the bottom surface portion 16 is placed on the boss 12, and the screw is inserted into the mounting hole 18 and screwed into the boss 12. The fixing bracket 15 is fixed to the boss 12 by. Since the support dowel 31 is supported by the support holes 8 and 19, the lock member 30 is swingably supported about the support dowel 31. Finally, the winding portion of the torsion spring 27 is fitted into the bent portion 21 of the fixing bracket 15, one end of which is hooked on the spring hooking dowel 34 and the other end of which is hooked on the spring hooking portion 26, and the lock member 30 is locked. Rotational habit in the B direction around the support dowel 31 and sliding habit in the C direction are imparted to the unlocking member 23.

Next, the operation of storing and removing the battery in the battery storing structure thus assembled will be described. First, when accommodating the battery 35, the battery 35 is inserted from diagonally below the battery storage chamber 2 and the inclined tip portion 38 is brought into contact with the lower surface of the holding piece 4 so that the tip portion 38 serves as a guide. The battery 4 is fitted into the holding groove 37 and the battery 35 is stored in the battery storage chamber 2. At this time, since the lock member 30 has a turning tendency in the B direction, the lock portion 32 faces the battery storage chamber 2 through the through hole 7, and the top plate 3 of the stored battery 35 is locked. The lock member 30 engages with the shaft 32 and rotates once in the direction opposite to the direction B against the torsion spring 27. Then, the notch 36 is aligned with the through hole 7, that is, the battery 35 is in the battery storage chamber. 2, when the lock portion seat 30 is rotated in the B direction again, the lock portion 32 faces the inside of the battery storage chamber 2 through the through hole 7 and engages with the notch portion 36. The battery 35 is locked in the battery storage chamber 2.

For removal, when the lock release member 23 is slid in the direction opposite to the C direction against the urging force of the torsion spring 27, the cam portion 25 engages with the cam portion 33 of the lock member 30. , The lock member 30 is rotated in the direction opposite to the B direction against the biasing force of the torsion spring 27. By this rotation, the lock portion 32 retracts from the battery storage portion 2, the engagement between the lock portion 32 and the cutout portion 36 is released, and the battery 35 can be removed.

As described above, the lock member 30 is swingably arranged along the outer surface of the battery storage chamber 2, and the lock member 30 is slidably arranged by the cam portion 25 of the lock releasing member 23. Since the lock member 30 is rotated to release the lock member 30 along the outer surface of the battery storage chamber 2, the space for storing these members in the direction of the arrow D in the drawing can be minimized. In addition, since these members can be efficiently mounted along the outer surface of the battery storage chamber 2 without providing a dead space, the device can be made smaller and thinner.

Further, since the lock releasing operation of the lock member 30 is performed by the cam portion 25 of the lock releasing member 23, the lock member 30 and the lock releasing member 23 do not depend on the position of the cutout portion 36 of the battery 35. Since the mounting position in the height direction and the mounting position in the longitudinal direction can be appropriately selected, the design or the internal mounting structure is not restricted by these members, and the degree of freedom in design is increased. Further, since all of these members are arranged outside the battery storage chamber 2, the assembly becomes easy. Further, since the lock releasing operation of the lock member 30 is performed by the cam portion 25 of the lock releasing member 23, the lock releasing operation can be smoothly performed.

A lock release member having a lock and a torsion spring that is interposed between the lock release member and the lock member and urges the lock part of the lock member so as to face the inside of the battery storage part. Since this is performed along the outer side surface of the battery storage portion, the device can be made smaller and thinner.

Further, since the lock release operation of the lock member is performed by the cam portion of the lock release member, the arrangement positions of the lock member and the lock release member in the height direction and the longitudinal direction are irrespective of the lock position of the battery. Since it is possible to select as appropriate, these members do not restrict the design or internal mounting structure, and the degree of freedom in design increases. Further, since all of these members are arranged outside the battery housing portion, the assembly becomes easy. Further, since the unlocking operation of the lock member is performed by the cam portion of the unlocking member, there are various effects such that the unlocking operation can be smoothly performed.
