2. Description of the Related Art Conventionally, in an automatic cleaner for cleaning a running road surface with a rotating brush arranged in a lower portion of a vehicle body and rotating in a direction perpendicular to the running road surface, a side brush is projected and fixed diagonally forward and outward of the vehicle body. Had a configuration.

[0003]

Conventionally, as described above, the side brush is projected and fixed diagonally forward and outward of the vehicle body. Therefore, when cleaning a corner of a room, the side brush contacts a wall or the like. There was a problem that corners could not be cleaned without avoiding the damage. The present invention has been made to solve the above-mentioned problems.

SUMMARY OF THE INVENTION The present invention relates to an automatic cleaner for cleaning a running road surface with a rotating brush which rotates in a direction perpendicular to the running road surface. A side brush holding mechanism protruding out of one of the bumpers is rotatably supported on the vehicle body, and a protrusion is provided at one end of the side brush holding mechanism near the vehicle body, and the other side brush holding mechanism is provided. The present invention has solved the above-mentioned problem as a configuration in which the protrusions are provided so as to be adjustable while a side brush is attached to an end so as to be pushed outward.

[0005]

[Function] When the side brush hits the wall, the side brush holding mechanism pivots to reduce the impact applied to the side brush holding mechanism, and when the side brush holding mechanism rotates over a certain angle, the protrusion contacts the bumper. To stop the vehicle.

The first dust collection box accommodated in the first dust collection box 13 is accommodated in the vehicle body 2, and the second dust collection box arranged downstream of the first dust collection box 12 is the control unit accommodated in the vehicle body 2. , 15 is a vacuum hose connecting between the hopper 7 and the first dust collection box 12, and 16 is an automatic cleaner 1
Is a battery that supplies energy for driving the battery.

The side brush mounting mechanism, which is a feature of the present invention, will be described in detail with reference to FIGS. 3 to 6. FIG. 3 is a plan view showing the mounting relationship with the vehicle body 2, and FIG. In the side view shown, reference numeral 18 denotes a first mounting bracket, which has an L-shape, and is fixed to the vehicle body 2 at an L-shaped vertical portion. Moreover, a pair of members are fixed to the vertical portion toward the front of the vehicle body 2 and a hole is formed in the center. On the other hand, a long hole is formed in the L-shaped horizontal portion.

Reference numeral 19 denotes a second mounting bracket, which has an L-shape similar to the first mounting bracket 18, the L-shaped vertical portion is located in front of the vehicle body, and a corner member is fixed to an end of the upper surface of the horizontal portion. A flat plate having a predetermined thickness is fixed to the lower surface.

On the other hand, an L-shaped member is fixed to the upper portion of the front wall of the vertical portion, and a flat plate is fixed to the lower portion thereof at predetermined intervals, and a hollow cylindrical body is horizontally elongated in front of the vertical wall of the L-shaped member. It is fixed to.

[0010] As shown in FIG. 5, the second mounting bracket 19 and the first mounting bracket 18 are composed of a corner member fixed to the end of the horizontal portion of the second mounting bracket 19 and the first mounting bracket 18. A pair of members are rotatably supported by pins.

As shown in FIG. 5, the bottle 26 mounted in the long hole of the L-shaped horizontal portion of the first mounting bracket 18 is slid forward to the front of the vehicle body and the second mounting bracket 18 is attached to the tip of a bolt. When the lower surface of the flat plate having a predetermined thickness fixed to the lower surface of the horizontal portion 19 contacts, the horizontal portion of the second mounting bracket 19 is pushed up, and the horizontal portion other than the flat plate is pushed down.

Reference numeral 20 denotes a third mounting bracket, as shown in FIG. 6, which is a member having a long U-shaped cross section, and a lower side being an L-shaped member above the front wall of the vertical portion of the second mounting bracket 19. Is inserted into the space formed by the lower plate and the lower plate, is rotatably supported by a pin, a brush rotation motor for rotating the brush is mounted on the upper side, the lower side and the upper side are fixed by a cylindrical member, A wedge-shaped member is fixed to the outer periphery of the cylindrical member.

As shown in FIG. 6, the cylindrical member of the third mounting bracket 20 serves to connect the brush rotating motor and the brush, and the shaft of the brush mounting member for fixing the brush and the brush rotating shaft. The rotating shaft of the motor is connected via a key, and a bearing is inserted between the outer periphery of the shaft of the brush mounting member and the inner periphery of the cylindrical member.

As shown in FIG. 6, a spring is mounted in a hollow cylinder fixed to the front of the vertical wall of the L-shaped member of the second mounting bracket 19 in a horizontally long manner, and a rod for pressing the spring is provided. Is inserted into a cylindrical body, a disk is rotatably mounted on one end of the rod body, and the disk is fitted in the wedge shape. When an external force is applied to the side brush, the spring is compressed and supported by a pin. In the position where
The bracket 20 rotates.

As shown in FIG. 3, a pair of projections are fixedly mounted on the rear end of the lower side of the third mounting bracket 20 or adjustable in the length direction or the width direction. When the motor 20 rotates by a predetermined angle or more, one of the protrusions comes into contact with the front bumper 9 and stops the traveling of the automatic cleaner 1.

[0016]

As described above, the present invention relates to an automatic cleaner for cleaning a running road surface with a rotating brush which is disposed below the vehicle body and rotates in a direction perpendicular to the running road surface. A side brush holding mechanism protruding outside one of the bumpers is rotatably supported on the vehicle body, and a protrusion is provided at one end near the vehicle body side of the side brush holding mechanism. Since the protrusions are provided so as to be adjustable while the side brushes are basically attached to the other end so as to be pushed outward, even if the side brush contacts a wall and a large external force acts, the side brush is held. The mechanism rotates to reduce the impact force, and also stops the automatic vacuum cleaner itself so that no more external force is applied to the side brush holding mechanism. Destruction of the holding mechanism can be prevented.
