Description

  The present invention relates to a mobile device charger and a height adjustment mechanism.

  Conventionally, a self-propelled cleaner that cleans a traveling surface (floor surface) while autonomously traveling on the floor surface is known. When the charge level of the battery of the self-propelled cleaner becomes below a predetermined amount, the self-propelled cleaner returns to the charger provided at the standby position of the self-propelled cleaner, The battery is charged by docking the traveling cleaner with the charging terminal of the self-propelling cleaner in contact with the power terminal of the charger.

  Then, the charging terminal of the self-propelled cleaner and the power supply of the charger are disturbed by the tilt of the charger due to the impact when the self-propelled cleaner is docked with the charger for the self-propelled cleaner. A charger provided with an anchor member for stabilizing the posture of the charger is known so as not to cause inconvenience in contact with the terminal (see, for example, Patent Document 1).

Moreover, in the charger 200 for self-propelled cleaners provided with the leg part 70 which has the support | pillar 60 which can be projected and retracted with respect to the bottom hole 51 of the bottom face of the charger main body 50 shown in FIG. As shown in b), the height of the charger main body 50 is adjusted according to the number of spacers S that can be attached so as to sandwich the support column 60, and the height of the power supply terminal 55 of the charger 200 is self-propelled. A technique for aligning with the height of the charging terminal of the machine is known.
Then, as shown in FIGS. 12 (a) and 12 (b), by adjusting the number of spacers S attached between the leg portion 70 and the charger main body 50, the vehicle running on a hard floor such as flooring is automatically adjusted. A self-propelled cleaner that travels so that the charging terminal 40 of the traveling cleaner 300 and the power terminal 55 of the charger 200 placed on the floor are aligned, or a soft floor such as a carpet is submerged. It is possible to align the positions of the 300 charging terminals 40 and the power supply terminal 55 of the charger 200 placed on the floor.
JP 2005-329223 A

However, in the case of the above prior art, if the thickness of the spacer S is reduced in order to make it possible to finely adjust the height of the power supply terminal 55 of the charger 200 (charger main body 50), the height adjustment range is larger. Therefore, there is a problem in that the number of parts increases and the cost increases.
Further, if the spacer S, which is an accessory part of the charger 200, is lost, there is a problem that the height of the charger 200 cannot be adjusted.

  An object of the present invention is to provide a mobile device charger and a height adjustment mechanism that can be adjusted in height.

In order to solve the above problems, the invention described in claim 1

A groove wall part formed with, a leg part having,
A housing having a column holding part that holds the column part so as to be movable in the extending direction of the column part;
A sliding portion having a sliding wall in sliding contact with the groove wall portion and formed with a piece portion slidable along the inclined groove;
With
By moving the slide portion in a direction parallel to the contact surface portion, the leg portion is moved in a direction in which the column portion extends.

The invention according to claim 3 is the height adjustment mechanism according to claim 2,
The slide portion includes a restricting portion that prevents the slide portion from being detached from the housing and restricts movement of the slide portion so that the piece portion does not come out of the inclined groove.

The invention according to claim 4 is the height adjusting mechanism according to claim 2 or 3,
The slide part includes an elastically deformable protrusion,
The housing is provided with a plurality of locking recesses for locking the protrusions along a direction in which the slide portion moves.

According to the first aspect of the present invention, the groove wall portion of the leg portion in the mobile device charger has a direction parallel to the contact surface portion in which the slide portion slides and a leg portion from the housing. An inclined groove is formed that has an inclination along the direction in which the direction in which the column part extends and exits and the direction in which the column part extends, so that when the slide part is moved in a direction parallel to the contact surface part, it is formed in the slide part When the piece portion is moved along the inclined groove of the groove wall portion, the force by which the piece portion pushes the inclined groove of the groove wall portion acts in the direction in which the support portion of the leg portion extends. Therefore, the leg can be made to appear and disappear with respect to the housing by the acting force.
In other words, by changing the degree to which the slide part is moved, the length of the leg protruding from the casing can be switched, and the floor surface of the casing is changed according to the length of the leg extending from the casing. The height from can be switched.
Therefore, in the mobile device charger, the height of the housing can be easily increased by sliding the slide portion in a direction parallel to the contact surface portion and switching the length of the leg portion extending downward from the housing. The casing adjusted to the height can be supported by the legs.
Therefore, this mobile device charger can suitably adjust the height of the housing.

  In addition, the mobile device charger prevents the slide portion from being detached from the housing by the restriction portion provided in the slide portion, and prevents the slide portion from slipping out of the inclined groove of the leg portion. The leg part can be prevented from being detached from the casing, so that the slide part and the leg part can move relative to the casing while the leg part and the sliding part do not come off the casing. It is possible to assemble to.

  The mobile device charger can lock the elastically deformable protrusion provided in the slide portion by a plurality of locking recesses provided in the housing along the direction in which the slide portion moves.

It is possible to switch the height from the floor in stages.

According to the second aspect of the invention, the leg portion enters and exits the groove wall portion of the leg portion in the height adjusting mechanism in a direction parallel to the contact surface portion, which is the direction in which the slide portion slides, and from the housing. Since the inclined groove having the inclination along the direction in which the direction in which the column part extends is combined is formed, when the slide part is moved in the direction parallel to the contact surface part, the slide part is formed. When the piece part moves along the inclined groove of the groove wall part, the force that the piece part pushes the inclined groove of the groove wall part acts in the direction in which the support part of the leg part extends, Due to the acting force, the leg portion can be moved in and out of the housing.
In other words, by changing the degree to which the slide part is moved, the length of the leg protruding from the casing can be switched, and the floor surface of the casing is changed according to the length of the leg extending from the casing. The height from can be switched.
Therefore, in the height adjustment mechanism, the height of the housing can be easily adjusted by sliding the slide portion in the direction parallel to the contact surface portion and switching the length of the leg portion extending downward from the housing. The casing adjusted to the height can be supported by the legs.
Therefore, the height adjustment mechanism can adjust the height of the housing suitably.

  According to the invention described in claim 3, it is needless to say that the same effect as that of the invention described in claim 2 can be obtained, and the height adjustment mechanism is configured so that the slide part is separated from the housing by the restriction part provided in the slide part. Can be prevented from coming off the sloping groove of the leg part so that the leg part does not come off from the slide part. It is possible to assemble the leg portion and the slide portion so as not to be detached from the casing while allowing the portion to move relatively.

  According to the invention described in claim 4, it is needless to say that the same effect as that of the invention described in claim 2 or 3 can be obtained, and the height adjusting mechanism is provided with an elastically deformable protrusion provided in the slide portion. Since the slide portion can be locked by a plurality of locking recesses provided in the housing along the moving direction, the slide portion protrudes into the continuous locking recesses when sliding. The part is locked in stages, and the height of the housing from the floor can be switched in stages by sliding the slide part in stages.

In addition, an operation button portion 32 d that is picked when the slide portion 30 is moved is formed on the outer surface on the distal end side of the lever portion 32.

As shown in FIG. 1, the charger main body 10 includes a charging unit (not shown) having a power supply terminal 11 for charging power supplied from a predetermined power source to a self-propelled cleaner, and a charging unit therein. And a housing 12 that accommodates and exposes the power terminal 11 to the outside.
The power supply terminal 11 is a terminal that contacts the charging terminal (see FIG. 12) of the self-propelled cleaner and supplies power to the battery (not shown) of the self-propelled cleaner.
As shown in FIGS. 1 and 4A to 4D, the housing 12 is a case body having a substantially rectangular parallelepiped shape, and the leg portion 20 is accommodated in the bottom surface portion via the slide portion 30. The leg accommodating part 12a which performs this, and the lever accommodating part 12b which accommodates the lever part 32 of the slide part 30 are formed.

The leg housing part 12a is provided with a column holding part 13 into which the column part 22 of the leg part 20 is inserted.
The support column holding portion 13 has a substantially rectangular parallelepiped box shape, and the inner surface shape thereof is substantially the same three-dimensional shape as the outer surface shape of the support column portion 22. And the support | pillar holding | maintenance part 13 hold | maintains the support | pillar part 22 inserted in the inner surface side of the support | pillar holding | maintenance part 13 so that the movement to the direction where the support | pillar part 22 extends is possible.

The lever accommodating portion 12b is provided with a locking portion 14 into which the protruding portion 32a of the slide portion 30 is engaged, and a guide groove 15 into which the restricting portion 32b of the slide portion 30 is engaged.
As shown in FIG. 5, the locking portion 14 is provided with a plurality of locking recesses 14 a for locking the inserted protrusions 32 a along the direction in which the slide portion 30 moves.
The guide groove 15 is a groove portion that allows the slide portion 30 to move along the direction in which the guide groove 15 extends by guiding the engaging restriction portion 32 b and the guide rib 32 c. Note that a restriction convex portion 16 is formed on one end side of the guide groove 15, and an alignment groove 17 is formed so as to sandwich the restriction convex portion 16.

  And by attaching the leg part 20 to the housing | casing 12 via the slide part 30, it becomes possible to arrange | position the charger main body 10 away from the floor surface, and the leg part 20 and the slide part 30 A height adjustment mechanism 90 is configured by the housing 12.

  Next, attachment of the leg part 20 and the slide part 30 to the housing | casing 12 of the charger main body 10 is demonstrated.

  First, as shown in FIG. 5, the protrusion 32 a of the slide portion 30 is engaged with the locking portion 14 of the housing 12, and as shown in FIGS. 6 and 7A, the restricting portion of the slide portion 30. The slide portion 30 is attached to the housing 12 such that the guide rib 32c is engaged with the guide groove 15 while aligning 32b with the alignment groove 17 of the housing 12.

  Next, as shown in FIG. 6, the upper opening side of the inclined groove 23 a is matched with the inclination of the piece portion 31 a of the sliding wall 31 of the slide portion 30 and the inclination of the inclined groove 23 a of the groove wall portion 23 of the leg portion 20. The column portion 22 of the leg portion 20 is inserted into the column holding portion 13 of the housing 12 so that the piece portion 31a is aligned with the frame portion 31a, and the leg portion 20 and the slide portion 30 are overlapped.

Next, the slide portion 30 in FIG. 7A is slid to the left in the drawing in the direction in which the leg portion 20 is contracted. When the sliding movement of the sliding portion 30 causes the regulating portion 32b of the sliding portion 30 to bend and over the slope of the regulating convex portion 16, the regulating portion 32b is engaged with the guide groove 15 as shown in FIG. Come in.
Then, as shown in FIG. 8A, the leg portion 20 and the slide portion 30 are attached to the housing 12 with the leg portion 20 being most extended.

When the restricting portion 32b is engaged with the guide groove 15, the tip surface of the restricting portion 32b is the contact surface of the restricting convex portion 16 even if the slide portion 30 in FIG. Therefore, the restricting portion 32b cannot pass over the restricting convex portion 16, and the restricting portion 32b does not slip out from the guide groove 15 to the alignment groove 17 side. Then, the slide part 30 cannot be detached from the housing 12.
Further, since the movement of the slide portion 30 is restricted when the restriction portion 32 b hits the restriction convex portion 16, the piece portion 31 a of the slide wall 31 of the slide portion 30 is inclined with respect to the groove wall portion 23 of the leg portion 20. Since it does not completely come out of the groove 23 a, the leg portion 20 cannot be detached from the slide portion 30.
That is, when the restricting portion 32 b of the slide portion 30 is engaged with the guide groove 15 of the housing 12, the slide portion 30 is attached so as not to be detached from the housing 12, and the leg portion 20 is not detached from the slide portion 30. The leg portion 20 and the slide portion 30 can move relatively with respect to the housing 12, but the leg portion 20 and the slide portion 30 do not come off the housing 12. Can be assembled to.

  Next, height adjustment of the charger main body 10 by the casing 12, the leg portion 20, and the slide portion 30 as the height adjustment mechanism 90 will be described.

When the lever portion 32 in the height adjustment mechanism 90 shown in FIG. 8A is moved to the left side in the drawing and the slide portion 30 is slid along the guide groove 15, the slide wall of the slide portion 30 is moved. As 31 moves so as to be in sliding contact with the groove wall portion 23 of the leg portion 20, the piece portion 31a also moves to the left in the figure.
When the piece portion 31a slides in accordance with the sliding movement of the sliding wall 31, the piece portion 31a moves so as to slide in the inclined groove 23a following the inclination of the inclined groove 23a of the groove wall portion 23. When the piece portion 31a pushes the inner surface of the inclined groove 23a upward, the leg portion 20 relatively moves in the direction approaching the housing 12 side, and FIG. 8 (b), FIG. 9 (a), FIG. As shown in (b), the leg 20 enters the housing 12.

On the other hand, if the slide part 30 is slid along the guide groove 15 so that the lever part 32 in the height adjusting mechanism 90 shown in FIG. As the moving wall 31 moves so as to be in sliding contact with the groove wall portion 23 of the leg portion 20, the piece portion 31a also moves to the right side in the drawing.
When the piece portion 31a slides in accordance with the sliding movement of the sliding wall 31, the piece portion 31a moves so as to slide in the inclined groove 23a following the inclination of the inclined groove 23a of the groove wall portion 23. When the piece portion 31a pushes the inner surface of the inclined groove 23a downward, the leg portion 20 moves relatively in a direction away from the housing 12 side, and as shown in FIG. Extends from the housing 12.

That is, the inclined groove 23a of the groove wall portion 23 is inclined along a direction in which the direction in which the slide portion 30 slides (lateral direction) and the direction in which the leg portion 20 enters and exits from the housing 12 (vertical direction) are combined. Therefore, when the piece 31a having substantially the same inclination as this inclination is slid in the horizontal direction, the piece 31a is moved along the inclined groove 23a. Since the force pushing the (inclined groove 23a) acts in the vertical direction on the leg portion 20, the leg portion 20 moves relatively in the vertical direction so that the column portion 22 moves in and out of the column holding portion 13. As a result, the leg 20 appears and disappears with respect to the housing 12.
Then, the height of the charger main body 10 from the floor surface is switched according to the length of the leg portion 20 extending from the housing 12.

In particular, as shown in FIG. 5, the height adjustment mechanism 90 is locked so that the protrusion 32a of the lever portion 32 that can be elastically deformed engages with the locking recess 14a of the locking portion 14. When the slide 30 is slid, the protrusion 32a is locked in stages to the plurality of continuous locking recesses 14a, and the height of the charger body 10 from the floor surface can be switched in stages. It can be done.
For example, in the height adjusting mechanism 90 shown in FIG. 8A, the length of the leg 20 extending most from the housing 12 is 10 mm. In the height adjusting mechanism 90 shown in FIG. When the leg portion 20 is accommodated in the body 12 and the length of the leg portion 20 that is most contracted is 0 mm, the eleven locking recesses 14a are formed in the locking portion 14 to enable 11-stage switching. The height of the charger main body 10 from the floor surface can be switched from 0 mm to 10 mm by 1 mm.

  Thus, the height adjustment mechanism 90 in which the leg portion 20 is attached to the housing 12 via the slide portion 30 can switch the arrangement of the leg portion 20 according to the degree to which the slide portion 30 is slid. The charger main body 10 can be arranged at a height corresponding to the arrangement of the legs 20 and the height at which the legs 20 support the housing 12.

Specifically, the leg portion 20 that extends downward from the bottom surface portion of the housing 12 by switching the arrangement of the slide portion 30 so as to switch the locking recess 14 a to which the protruding portion 32 a of the lever portion 32 is locked. The height at which the charger main body 10 is separated from the floor surface can be adjusted by adjusting the length of.
Then, the power source terminal 11 of the charger 100 and the charging terminal of the self-propelled cleaner are influenced by the material of the floor surface (flooring, carpet, etc.) and the weight of the charger 100 and the self-propelled cleaner on the floor surface. If the height position of the battery charger is shifted, the position of the power supply terminal 11 and the charge terminal is adjusted by adjusting the height of the charger 100 from the floor surface of the charger body 10, and the power supply terminal 11. And the charging terminal can be adjusted so that predetermined contact can be made.

As described above, the charger 100 for the self-propelled cleaner according to the present invention including the height adjustment mechanism 90 including the leg portion 20, the slide portion 30, and the housing 12 includes the slide portion 30. The height at which the charger main body 10 is separated from the floor surface can be adjusted by switching the arrangement of the above by slide movement and adjusting the length of the leg 20 extending from the housing 12.
Therefore, the charger 100 including the height adjusting mechanism 90 can suitably adjust the height of the charger body 10 and can easily switch the height of the power supply terminal 11.
That is, it can be said that the charger 100 and the height adjusting mechanism 90 are a mobile device charger and a height adjusting mechanism capable of suitably adjusting the height.

  In the above embodiment, the height adjusting mechanism 90 capable of performing 11-stage height switching by the locking portion 14 in which the 11 locking recesses 14a are formed has been described. The present invention is not limited to this, and the number of the locking recesses 14a, the number of height switching steps, the height per step, etc. are arbitrary, and the mobile device (self-propelled cleaner) or the charger is used. A suitable number or shape may be used depending on the specifications.
