Hereinafter, a method of coupling the cleaner 300 to the charging base 10 will be described.

6 is a view illustrating a cleaner coupled to a charging stand. Specifically, FIG. 6 (a) shows a state in which the cleaner is guided by the cleaner guide, and FIG. 6 (b) shows the state in which the locking unit is coupled to the cleaner.

Referring to FIG. 6, the cleaner body 310 may move forward and backward along the cleaner guide 137 while being supported by the cleaner guide 137. Accordingly, the cleaner body 310 may selectively contact the first charging terminal 113.

The locking part 120 may be rotatably connected to the first body 110 within a predetermined angle range. FIG. 6A illustrates a state in which the locking unit 120 is rotated upward (clockwise in FIG. 6A). The locking unit 120 may be referred to as an “open state” in which the locking unit 120 is rotated upward as much as possible. On the contrary, a state in which the locking unit 120 is coupled to the cleaner 300 may be referred to as a "closed state".

The locking part 120 may be provided with a pressing part 123. The pressing part 123 may be provided inside the locking part 120. The pressing part 123 may be pressed by the battery housing 320 while the cleaner body 310 moves along the guide part 116.

When the battery housing 320 presses the pressing part 123, the locking part 120 may operate.

Specifically, when the locking unit 120 operates, the locking unit 120 may rotate forward (counterclockwise in FIG. 6B) to be coupled to the outer circumferential surface of the battery housing 320. Accordingly, the locking part 120 may cover at least a portion of the battery housing 320.

When the locking unit 120 rotates forward, an elastic member (not shown) may provide an elastic force to maintain the locking unit 120 rotated forward. Accordingly, the locking part 120 may serve to fix the battery housing 320 to the first body 110.

The battery housing 320 has a fixing protrusion 322 to be coupled to the locking unit 120 is formed. In a state where the cleaner 3000 is seated on the cleaner guide 137, the fixing protrusion 322 faces upward. Therefore, the locking part 120 may be coupled to the fixing protrusion 322.

In the present invention, since the locking part 120 is coupled to the fixing protrusion 322 of the battery housing 320, the locking part 120 is forcibly pulled out of the cleaner 300 in the closed position to clean the cleaner 300. ) May be prevented from remaining in the charger 100 even if the battery is mounted in the cleaner 300.

That is, only the cleaner main body 310 may be prevented from being separated from the charging stand 100 while the battery installed in the cleaner 300 remains in the charging stand 100.

Hereinafter, a detailed configuration and operating principle of the locking unit 120 will be described in detail.

7 is a view showing a state in which the locking unit is removed from the first body, Figure 8 is a view showing the back of the locking unit, Figure 9 is a perspective view showing a fixing groove formed in the locking unit.

3, 7 to 9, the locking part 120 includes a cover part 121 and a pressing part 123. The cover part 121 may have an arch shape, and the pressing part 123 may be connected to a bottom surface of the cover part 121.

When the locking part 120 is coupled to the cleaner 300, the cover part 121 surrounds at least a portion of the battery housing 320 of the cleaner 300.

The rear surface 123a of the pressing part 123 is provided with a first hinge part 124 rotatably coupled to the first body 110.

The first hinge portion 124 is hinged to the hinge coupling portion 1104 provided in the first body 110. Accordingly, the locking part 120 may rotate in the up and down direction about the first hinge part 124. As shown, the first hinge portion 124 may be configured in a pair.

The upper rotational range of the locking unit 120 may be limited by the rear surface 125 of the locking unit 120. That is, when the locking part 120 rotates upward by a predetermined angle, the rear surface 125 of the locking part 120 contacts the first surface 1107 (upper stopper) of the first body 110. The rotation range of the locking unit 120 in the upper direction may be limited.

The first body 110 is provided with a front cover 1101 for protruding the first charging terminal 113.

The locking part supporter 1100 is provided on an upper side of the front cover 1101. The locking part supporter 1100 may be provided with a lower stopper 1102 for limiting the rotation range toward the lower side of the locking part 120.

An opening 1103 may be formed in the locking part supporter 1100. A portion of the locking part 120 may be inserted into the opening 1103 to be provided with an elastic force for the operation of the locking part 120. A link member is provided inside the first body 110 to transmit the elastic force to the locking unit 120.

A second hinge portion 126 connected to the link member is provided on the rear surface 123a of the pressing portion 123.

The lower surface of the cover portion 121 may be provided with a fixing groove 121a for accommodating the fixing protrusion 322 provided in the cleaner 300. The fixing protrusion 322 may be accommodated in the fixing groove 121a while the locking unit 120 is rotated in the counterclockwise direction with reference to FIG. 6.

Since the fixing protrusion 322 should be inserted into the fixing groove 121a during the rotation of the locking unit 120, the size of the fixing groove 121a may be somewhat larger than that of the fixing protrusion 322. have. Alternatively, since the fixing protrusion 322 should be inserted into the fixing groove 121a while the locking unit 120 rotates, the lower surface of the cover unit 121 is closed in the state in which the locking unit 120 is closed. The battery housing 320 may be spaced apart. In this state, the fixing force of the fixing protrusion 322 and the fixing groove 121a may be weak.

Therefore, in the present invention, the fixing rib 121b may be formed on the lower surface of the cover portion 121 so that the fixing force of the fixing protrusion 322 and the fixing groove 121a is increased. The fixing rib 121b is formed around the fixing groove 121a, and the fixing rib 121b is formed at the front of the fixing protrusion 322 in a state in which the fixing protrusion 322 is accommodated in the fixing groove 121a. It can be located at. In the present invention, the front of the fixing protrusion 322 is a direction from the first body 110 toward the battery housing.

That is, the fixing protrusion 322 is located between the fixing rib 121b and the first surface 1107 of the first body 110.

The fixing rib 121b may cover at least one surface of the fixing protrusion 322 in the state in which the fixing protrusion 322 is accommodated in the fixing groove 121a. In this case, the fixing rib 121b may contact the fixing protrusion 322 in a state where the fixing protrusion 322 is accommodated in the fixing groove 121a.

Therefore, when the locking unit 120 is to be separated from the cleaner 300 in the closed state, not only the fixing groove 121a but also the fixing rib 121b acts as a resistance of the fixing protrusion 322. The separation of the cleaner 300 may be prevented.

Meanwhile, a part 325 of the battery 324 mounted on the battery housing 320 is exposed to the outside of the battery housing 320.

The cover part 121 may further include a cover rib 121c covering a portion 325 of the battery 324 exposed to the outside of the battery housing 320.

When removing the cleaner 300 while the locking unit 120 is closed, the cover rib 121c covers a part of the battery 324 mounted to the battery housing 320. Therefore, since the cover rib 121c acts as a resistance on a path for the battery 324 to move, the cleaner 300 may be further prevented from being separated.

Therefore, according to the present invention, since the locking force of the locking unit 120 and the cleaner is improved, even if an external force is applied to the cleaner while the cleaner 300 is mounted on the holder 100, the cleaner 300 Is separated from the cradle 10 can be prevented from falling.

Hereinafter, the operating principle of the locking unit 120 will be described in detail.
