Detailed implementation manners

[0023] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0024] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0025] As Figures 1-7 shown, a floor washing machine obstacle avoidance test device includes a main body platform 1. A reversing platform 2 is arranged in front of the main body platform 1. A workbench 3 is arranged above the main body platform 1. The horizontal height at the top of the reversing platform 2 is the same as the horizontal height at the top of the workbench 3. A central cavity 4 is opened inside the workbench 3. A reciprocating pushing mechanism 6 is arranged inside the central cavity 4. A bottom cavity 5 is opened inside the main body platform 1. A driving mechanism 7 is arranged inside the bottom cavity 5. Two empty slots are opened on the surface of the workbench 3, and the empty slots are located at the end corners of the central cavity 4. An obstacle mechanism 8 is movably arranged in the empty slots. A rotating mechanism 22 is arranged inside the reversing platform 2. By arranging the reciprocating pushing mechanism 6 inside the central cavity 4, under the control of the driving mechanism 7, the reciprocating pushing mechanism 6 can enable two ways of the obstacle mechanism 8 to be reflected alternately on the surface of the workbench 3, so that obstacles can be set within the driving range of the floor washing machine. At the same time, by arranging the rotating mechanism 22, the turning operation of the floor washing machine can be realized, which is convenient for repeatedly testing the floor washing machine.

[0026] The reciprocating pushing mechanism 6 includes a first gear 9 and a second gear 10. The first gear 9 and the second gear 10 are rotatably installed in the middle of the central cavity 4, and the first gear 9 and the second gear 10 are meshed. When the first gear 9 rotates, the second gear 10 will also rotate, and the rotation directions of the first gear 9 and the second gear 10 are opposite. A first sector rack 11 is fixedly arranged above the first gear 9, and a second sector rack 12 is fixedly arranged above the second gear 10. The directions of the first sector rack 11 and the second sector rack 12 are opposite. Two moving platforms 13 are symmetrically and slidably arranged inside the central cavity 4. The moving platform 13 includes a first moving platform 33 and a second moving platform 34. The first moving platform 33 and the second moving platform 34 are respectively arranged on both sides of the first gear 9 and the second gear 10. The first moving platform 33 and the second moving platform 34 are both arranged in a T shape, and a mating rack 14 is arranged on the end faces of the tops of the first moving platform 33 and the second moving platform 34. The mating rack 14 meshes with the first sector rack 11 and the second sector rack 12. Limit strips 15 are arranged below the first moving platform 33 and the second moving platform 34. The bottoms of the limit strips 15 are fixedly installed in the central cavity 4. The bottoms of the first moving platform 33 and the second moving platform 34 are respectively movably clamped in the limit strips 15. When the first gear 9 and the second gear 10 rotate, the first sector rack 11 and the second sector rack 12 on their tops will also rotate. Thus, the first sector rack 11 and the second sector rack 12 can control the first moving platform 33 and the second moving platform 34 in sequence. When the first gear 9 rotates clockwise and the second gear 10 rotates counterclockwise, the first sector rack 11 drives the first moving platform 33 to move forward, and the second sector rack 12 drives the second moving platform 34 to move forward. The first moving platform 33 and the second moving platform 34 can move forward to the front of the central cavity 4 at the same time. After rotating a certain angle, the directions of the first sector rack 11 and the second sector rack 12 are swapped. At this time, the first sector rack 11 drives the second moving platform 34 to move backward, and the second sector rack 12 drives the first moving platform 33 to move backward. The first moving platform 33 and the second moving platform 34 can move backward to the rear of the central cavity 4 at the same time. When the first gear 9 rotates, the first moving platform 33 and the second moving platform 34 can make reciprocating motions inside the central cavity 4.

[0027] The obstacle mechanism 8 includes a lifting block 17. A T-shaped slide bar 18 is provided on the inner wall of the central cavity 4. The surface of the lifting block 17 is slidably clamped on the surface of the T-shaped slide bar 18. A connecting rod 16 is connected between the end of the moving table 13 and the bottom of the lifting block 17 through a rotating shaft. When the first moving platform 33 and the second moving platform 34 move forward towards the front of the central cavity 4 at the same time, the second moving platform 34 pushes the lifting block 17 under the action of the connecting rod 16, causing the lifting block 17 to move upward. At the same time, the first moving platform 33 pulls the lifting block 17 under the action of the connecting rod 16, causing the lifting block 17 to move downward. At this time, the lifting block 17 at the front end of the workbench 3 protrudes from the workbench 3, while the lifting block 17 at the rear end of the workbench 3 retracts into the central cavity 4. When the first moving platform 33 and the second moving platform 34 can move backward towards the rear of the central cavity 4 at the same time, the first moving platform 33 pushes the lifting block 17 under the action of the connecting rod 16, causing the lifting block 17 to move upward. At the same time, the second moving platform 34 pulls the lifting block 17 under the action of the connecting rod 16, causing the lifting block 17 to move downward. At this time, the lifting block 17 at the front end of the workbench 3 retracts into the central cavity 4, while the lifting block 17 at the rear end of the workbench 3 protrudes from the workbench 3. The two modes of the obstacle mechanism 8 can be staggered on the surface of the workbench 3, and obstacles can be set within the range where the floor washer travels.

[0028] The driving mechanism 7 includes a stepping motor 19 and a third gear 20. The output end of the stepping motor 19 is connected to the first gear 9. A driving rod is provided at the center of the third gear 20, and the top end of the driving rod is connected to the second gear 10. The stepping motor 19 can drive the first gear 9 to rotate, and the driving rod and the third gear 20 can ensure the stability of the second gear 10 during rotation.

[0029] The rotating mechanism 22 includes a fourth gear 26. A conveying rod is arranged at the center of the fourth gear 26. A turntable 28 is installed at the top end of the conveying rod. Driven by the rotation of the fourth gear 26, the conveying rod can drive the turntable 28 to rotate. A frame-shaped pushing bracket 23 is arranged outside the fourth gear 26. A second pushing rack 24 is arranged on the inner wall of the frame-shaped pushing bracket 23. The second pushing rack 24 meshes with the fourth gear 26. An extension rod 25 is arranged at the end of the frame-shaped pushing bracket 23. The extension rod 25 movably penetrates through the reversing table 2 and the main body table 1. A spring 27 is arranged at the other end of the frame-shaped pushing bracket 23. The elastic force of the spring 27 can push the frame-shaped pushing bracket 23 towards the rear of the device, so that the extension rod 25 penetrates through the reversing table 2 and the main body table 1 when not stressed. A first pushing rack 21 is slidably arranged inside the bottom cavity 5. The first pushing rack 21 meshes with the third gear 20, and the first pushing rack 21 is aligned with one of the extension rods 25. When the third gear 20 rotates, the first pushing rack 21 can move inside the bottom cavity 5. When the third gear 20 rotates counterclockwise, the first pushing rack 21 will move towards the front of the bottom cavity 5. At this time, the first pushing rack 21 can push the extension rod 25 into the inside of the reversing table 2. At this time, the second pushing rack 24 on the inner wall of the frame-shaped pushing bracket 23 can drive the fourth gear 26 to rotate. When the floor washer is at the top of the turntable 28, the frame-shaped pushing bracket 23 drives the fourth gear 26 to rotate 180 degrees, realizing the turning operation of the floor washer, which is convenient for repeatedly testing the floor washer multiple times.

[0030] The top of the turntable 28 is at the same horizontal level as the top of the reversing table 2, ensuring that the floor washer can smoothly move from the workbench 3 to the surface of the reversing table 2 and the turntable 28. A limiting frame 30 is arranged at the top of the reversing table 2. The limiting frame 30 is located on the side of the turntable 28 and can block the outside of the turntable 28, playing a limiting role. A limiting ring 29 is arranged on the outer surface of the turntable 28. The limiting ring 29 is movably clamped in the reversing table 2 to ensure the stability of the turntable 28 during rotation.

[0031] On one side of the main body table 1 away from the reversing table 2, an inclined plate 31 is arranged. The two ends of the inclined plate 31 are connected to protruding blocks 32 through rotating shafts. The other ends of the two protruding blocks 32 are fixedly connected to the workbench 3. The floor washer can move to the surface of the workbench 3 through the inclined plate 31.

[0032] Support frames are fixedly arranged at the four corners of the top of the main body table 1. The tops of the support frames are fixedly connected to the workbench 3 to strengthen the stability of the connection between the main body table 1 and the workbench 3. Railings are installed on the side of the workbench 3 to protect the floor washer and prevent the floor washer from tipping and falling.

[0033] Working principle: First, the floor washer can be moved to the surface of the workbench 3 through the inclined plate 31. Then, the stepping motor 19 drives the first gear 9 to rotate. Since the first gear 9 meshes with the second gear 10, when the first gear 9 rotates, the second gear 10 will also rotate, and the rotation directions of the first gear 9 and the second gear 10 are opposite. When the first gear 9 and the second gear 10 rotate, the first sector rack 11 and the second sector rack 12 at their tops will also rotate. Thus, the first sector rack 11 and the second sector rack 12 can control the first moving platform 33 and the second moving platform 34 in sequence. When the first gear 9 rotates clockwise and the second gear 10 rotates counterclockwise, the first sector rack 11 drives the first moving platform 33 to move forward, and the second sector rack 12 drives the second moving platform 34 to move forward. The first moving platform 33 and the second moving platform 34 can move forward to the front of the central cavity 4 simultaneously. And under the action of the connecting rod 16, the second moving platform 34 pushes the lifting block 17, causing the lifting block 17 to move upward. At the same time, the first moving platform 33 pulls the lifting block 17 under the action of the connecting rod 16, causing the lifting block 17 to move downward. At this time, the lifting block 17 at the front end of the workbench 3 protrudes from the workbench 3, while the lifting block 17 at the tail end of the workbench 3 retracts into the central cavity 4. Then, after rotating a certain angle, the directions of the first sector rack 11 and the second sector rack 12 are swapped. At this time, the first sector rack 11 drives the second moving platform 34 to move backward, and the second sector rack 12 drives the first moving platform 33 to move backward. The first moving platform 33 and the second moving platform 34 can move backward to the rear of the central cavity 4 simultaneously. And under the action of the connecting rod 16, the first moving platform 33 pushes the lifting block 17, causing the lifting block 17 to move upward. At the same time, the second moving platform 34 pulls the lifting block 17 under the action of the connecting rod 16, causing the lifting block 17 to move downward. At this time, the lifting block 17 at the front end of the workbench 3 retracts into the central cavity 4, while the lifting block 17 at the tail end of the workbench 3 protrudes from the workbench 3. That is, when the first gear 9 rotates, the first moving platform 33 and the second moving platform 34 can make reciprocating motions inside the central cavity 4. The two ways of the obstacle mechanism 8 can be alternately reflected on the surface of the workbench 3, and obstacles can be set within the range where the floor washer travels. Finally, after the floor washer moves from the workbench 3 to the surface of the turntable 28, when the stepping motor 19 drives the third gear 20 to rotate counterclockwise, the first push rack 21 will move forward to the front of the bottom cavity 5. At this time, the first push rack 21 can push the extension rod 25 into the inside of the reversing platform 2. At this time, the second push rack 24 on the inner wall of the frame-shaped push rack 23 can drive the fourth gear 26 to rotate. When the floor washer is at the top of the turntable 28, the frame-shaped push rack 23 drives the fourth gear 26 to rotate 180 degrees, realizing the turning operation of the floor washer, which is convenient for repeatedly testing the floor washer multiple times.
