The rail is restricted from moving in the direction of coming out of the shoe of the battery mounting part 25. - 特許庁

The removal restriction opening 83 is not limited to the removal restriction opening 83 provided in the flange portion 82 . Removal restriction port 83 mechanically contacts power supply terminal 53 connected to power reception terminal 51 , such as a notch provided in flange portion 82 , an edge of flange portion 82 , and a side wall of the case of secondary battery 13 . Any portion that prevents the removal of the secondary battery 13 is sufficient.

The vacuum cleaner 2 according to this embodiment includes a disconnection mechanism that disconnects the power receiving terminal 51 and the power supply line 47 when the secondary battery 13 is removed from the vacuum cleaner main body 12 instead of the removal restricting portion 75 . It's okay to be prepared. Unlike the removal regulation part 75 that regulates removal of the secondary battery 13 when the power supply line 47 is connected to the power reception terminal 51 , the connection release mechanism is interlocked with the removal of the secondary battery 13 to disconnect the power reception terminal 51 . The connection with the feed line 47 is released.

For example, when the terminal connection restricting portion 73 closes the through hole 71 , the connection release mechanism consumes the energy of the closing elastic member 77 to push the power supply line 47 out of the power receiving terminal 51 . In this case, the disconnection mechanism is composed of a known mechanism such as a link mechanism or a cam mechanism that converts the energy of the closing elastic member 77 into a force that pushes the power supply line 47 out of the power receiving terminal 51 . Further, the disconnection mechanism pushes the power feeding path 47 out of the power receiving terminal 51 by a force applied to the operation portion 62 when the lock mechanism 61 is unlocked, for example. In this case, the disconnection mechanism is composed of a known mechanism such as a link mechanism or a cam mechanism that converts the force applied to the operation portion 62 into a force that pushes the power supply line 47 out of the power receiving terminal 51 .

Furthermore, the disconnection mechanism may have a hole (orifice) in a flange provided on the secondary battery 13, for example. In this case, the through hole 71 of the cleaner body 12 preferably opens in the direction in which the secondary battery 13 moves when the secondary battery 13 is attached to or detached from the battery mounting portion 25 . The hole of the secondary battery 13 overlaps with the through-hole 71 when the secondary battery 13 is attached to the battery mounting portion 25 , so that the power supply terminal 53 can be connected to the power receiving terminal 51 while the secondary battery 13 is attached to the battery mounting portion 25 . When removed from the portion 25 , the power supply terminal 53 is extracted from the power reception terminal 51 by the movement of the secondary battery 13 .

The charging device 3 is also a storage base for the cleaner main body 12 . The charging device 3 restricts the secondary battery 13 from being removed from the cleaner main body 12 when the charging device 3 vacuum cleaner 2 is attached and the power supply line 47 can supply power to the secondary battery 13. A second removal restricting portion 85 is provided.

The second removal restricting portion 85 is a part of the side wall portion 43 of the charging device 3, and hides the operation portion 62 of the locking mechanism 61 when the cleaner main body 12 is housed in the charging device 3. impede. The second removal regulating part 85 hides the operation part 62 of the lock mechanism 61 to inhibit the operation regardless of whether the power supply line 47 is connected to the power receiving terminal 51 of the cleaner body 12 or not.

The second removal restricting portion 85 is a part of the side wall portion 43 of the charging device 3 and inhibits the movement of the lever 66 of the locking mechanism 61 when the cleaner main body 12 is housed in the charging device 3. can be

In addition, the second removal restricting portion 85 is configured to lock the cleaner main body 12 in a state where the cleaner main body 12 is accommodated in the charging device 3 by the surface to be cleaned on which the charging device 3 is installed or the wall surface on which the charging device 3 is installed. The operation part 62 of 61 may be hidden to hinder the operation. In the floor-mounted charging device 3, the operating portion 62 of the lock mechanism 61 faces the surface to be cleaned and cannot be pushed in, or the lever 66 of the lock mechanism 61 contacts the surface to be cleaned and cannot be moved. , the cleaner body 12 is stored in the vicinity of the surface to be cleaned in a recumbent posture (posture in which the cleaner body 12 is laid down in the longitudinal direction). In the wall-mounted charging device 3, the vacuum cleaner main body 12 is arranged so that the operating portion 62 of the lock mechanism 61 faces the wall surface and cannot be pushed in, or the lever 66 of the lock mechanism 61 contacts the wall surface and cannot be moved. , the cleaner body 12 is stored near the wall surface in an upright posture (a posture in which the longitudinal direction of the cleaner body 12 is directed vertically).
