[0047] Next, the technical solutions in the present application will be described with reference to the accompanying drawings.

[0048] This embodiment provides an automatic turntable system 10, which can solve the problem that the floor sweeper 10A in the prior art is difficult to enter the base station by backing up.

[0049] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , Figure 1 which are schematic diagrams of the floor sweeper 10A climbing to the automatic turntable system 10 in this embodiment, Figure 2 which is a schematic diagram of the floor sweeper 10A in the automatic turntable system 10 in this embodiment, Figure 3 which is a schematic diagram of the floor sweeper 10A in the cleaning posture in the schematic diagram when the floor sweeper 10A is in the automatic turntable system 10, Figure 4 which is a perspective view of the automatic turntable system 10 in this embodiment, Figure 5 which is an exploded perspective view of the automatic turntable system 10 in this embodiment.

[0050] The automatic turntable system 10 includes a base 11, a turntable assembly 12, and a drive assembly 13. The turntable assembly 12 is rotatably connected to the base 11. The turntable assembly 12 includes a turntable body 14 and an annular rack 15 provided on the turntable body 14. The drive assembly 13 is provided on the base 11 and the drive gear of the drive assembly 13 meshes with the annular rack 15.

[0051] The drive assembly 13 drives the turntable body 14 to rotate a predetermined angle to switch the floor sweeper 10A located on the turntable body 14 between its traveling posture and cleaning posture.

[0052] In the above implementation process, the floor sweeper 10A travels to the turntable body 14 in its normal traveling posture, that is, in the normal forward manner. Through the operation of the drive assembly 13, the turntable body 14 rotates a predetermined angle to adjust the orientation of the floor sweeper 10A so that the floor sweeper 10A is adjusted to the cleaning posture.

[0053] When the automatic turntable system 10 is applied to a base station, refer to Figure 1 and Figure 2 , since the forward climbing angle of the sweeper 10A is large, the sweeper 10A can easily enter the base station in a walking posture and is located on the turntable body 14. Refer to Figure 3 . By the operation of the automatic turntable system 10, after the sweeper 10A is rotated by a predetermined angle, the sweeper 10A is in a cleaning posture relative to the entire automatic turntable system 10, that is, the mopping cloth 30 of the sweeper 10A corresponds to the cleaning station of the base station, so that the cleaning and other operations can be successfully completed in the base station. After the cleaning is completed, the automatic turntable system 10 operates to rotate the sweeper 10A to the walking posture, and then it can exit the base station.

[0054] In the present disclosure, the ring rack 15 is fixed to the lower surface of the turntable body 14, and the turntable body 14 and the ring rack 15 are coaxial.

[0055] In the above implementation process, since the turntable body 14 and the ring rack 15 are coaxial, when the driving assembly 13 operates and the driving gear rotates, it drives the ring rack 15 and the turntable body 14 to rotate synchronously, thereby quickly driving the sweeper 10A to rotate to adjust the orientation of the sweeper 10A. At the same time, the ring rack 15 is located on the lower surface of the turntable body 14, which also avoids the ring rack 15 interfering with the sweeper 10A.

[0056] Please refer to Figure 6 , Figure 6 which is a perspective view of a partial structure of the automatic turntable system 10.

[0057] In the present disclosure, the automatic turntable system 10 further includes a turntable guide wheel assembly. The turntable guide wheel assembly is arranged on the base 11 and abuts against the ring rack 15.

[0058] In the above implementation process, the turntable guide wheel assembly guides the ring rack 15, so that under the drive of the driving assembly 13, the ring rack 15 can smoothly rotate by a predetermined angle to complete the smooth switching of the sweeper 10A between the walking posture and the cleaning posture; at the same time, the turntable guide wheel assembly also plays a role in supporting the ring rack 15 and the turntable body 14 to ensure that the ring rack 15 and the turntable body 14 can smoothly rotate relative to the base 11.

[0059] In the present disclosure, the turntable guide wheel assembly includes a plurality of guide wheel units 16. The plurality of guide wheel units 16 are arranged at intervals along the length direction of the ring rack 15 to support the ring rack 15 and rollingly cooperate with the ring rack 15.

[0060] In the above implementation process, multiple guide wheel units 16 jointly play a guiding and supporting role to jointly share the acting forces of the turntable assembly 12 and the sweeping robot 10A, thereby improving the service life of the turntable guide wheel assembly.

[0061] It should be noted that in combination with Figure 7 and Figure 8 , the guide wheel unit 16 includes a first guide unit 16a and a second guide unit 16b.

[0062] The number of the first guide units 16a is two, and the two first guide units 16a are arranged at intervals. The first guide unit 16a includes a support frame 16c and rollers arranged on the support frame 16c. The support frame 16c is fixed on the base 11, and the rollers abut against the annular rack 15.

[0063] The number of the second guide units 16b is two. The two first guide units 16a are located between the two second guide units 16b, and the second guide unit 16b is located outside the adjacent first guide unit 16a. In the present disclosure, the second guide unit 16b includes rollers, and the rollers are rotatably embedded in the base 11 through a rotating shaft 17. When the annular rack 15 rotates to a certain angle, the annular rack 15 will contact the second guide unit 16b, and the second guide unit 16b supports the annular rack 15.

[0064] Please combine Figure 5 and Figure 9 , Figure 9 which is the assembly drawing of the trigger rod 18, the first photoelectric switch 19 and the second photoelectric switch 20 in this embodiment.

[0065] The turntable body 14 is provided with a rotating shaft 17. The rotating shaft 17 passes through the base 11, and the rotating shaft 17 is configured with a trigger rod 18. The lower surface of the base 11 is configured with a first photoelectric switch 19 and a second photoelectric switch 20 arranged at intervals. When the driving assembly 13 drives the turntable body 14 to rotate a predetermined angle, the trigger rod 18 triggers the first photoelectric switch 19 or the second photoelectric switch 20 to control the driving assembly 13 to stop working.

[0066] During the above implementation process, when the sweeper 10A needs to be switched from the traveling posture to the cleaning posture, the turntable body 14 rotates. After the turntable body 14 rotates a predetermined angle, the trigger rod 18 will trigger the first optoelectronic switch 19, and the first optoelectronic switch 19 will feedback to the drive assembly 13, causing the drive assembly 13 to stop working, ensuring that the sweeper 10A is in the correct orientation, that is, the cleaning posture. When the sweeper 10A needs to be switched from the cleaning posture to the traveling posture, the turntable body 14 rotates reversely. After the turntable body 14 rotates reversely a predetermined angle, the trigger rod 18 will trigger the second optoelectronic switch 20, and the second optoelectronic switch 20 will feedback to the drive assembly 13, causing the drive assembly 13 to stop working, ensuring that the sweeper 10A is in the correct orientation, that is, the traveling posture.

[0067] In the present disclosure, the predetermined angle is one hundred and eighty degrees.

[0068] During the above implementation process, the predetermined angle is one hundred and eighty degrees, which indicates that the sweeper 10A can rotate one hundred and eighty degrees to switch its traveling posture and cleaning posture, and can be combined with Figure 2 and Figure 3 it can be seen. It should be noted that the cleaning posture corresponds to the cleaning station of the base station. When the specific position of the cleaning station of the base station changes, its predetermined angle also changes accordingly. For example, in other embodiments, the predetermined angle can be ninety degrees or one hundred and twenty degrees, etc.

[0069] In the present disclosure, the turntable body 14 is provided with a stop block 21, and the stop block 21 is used to cooperate with the sweeper 10A to realize the braking of the sweeper 10A.

[0070] During the above implementation process, when the sweeper 10A advances into the turntable body 14, the front collision of the sweeper 10A touches the stop block 21 on the turntable, and then it can immediately stop on the turntable, so that the automatic turntable system 10 works.

[0071] In the present disclosure, a side enclosure 22 is formed on the surface of the base 11, and two side guide wheel units 23 are provided at intervals on the side enclosure 22. Combining Figure 10 , Figure 10 is a perspective view of the side guide wheel unit 23 in this embodiment.

[0072] The side guide wheel unit 23 includes a side guide wheel 24 and a vertical guide wheel 25. The side guide wheel 24 rolls around the vertical direction and is used for fixed cooperation with the wall surface of the sweeper 10A. The vertical guide wheel 25 rolls around the horizontal direction and abuts against the surface of the turntable body 14.

[0073] During the above implementation process, when the floor sweeper 10A advances into the turntable body 14, the side guide wheels 24 guide the floor sweeper 10A so that the floor sweeper 10A can accurately and smoothly enter the side enclosure 22 of the base 11 and be located on the turntable body 14. The vertical guide wheels 25 abut against the surface of the turntable body 14 and play a role in supporting and guiding the rotation of the turntable body 14.

[0074] In the present disclosure, the base 11 includes a base body 26 and a bottom cover 27. The turntable assembly 12 is provided on the base body 26, and the drive assembly 13 is located between the base body 26 and the bottom cover 27. One end of the base body 26 forms a slope 28.

[0075] During the above implementation process, the floor sweeper 10A can smoothly pass through the slope 28 in a walking posture and enter the base body 26. The drive assembly 13 is located between the base body 26 and the bottom, and can be well protected to avoid the drive assembly 13 being exposed outside and increasing the risk of being damaged. It should be noted that in the present disclosure, the drive assembly 13 includes a drive motor, a gearbox, and a drive gear provided on the output shaft of the gearbox.

[0076] It should be noted that in the present disclosure, a base station is also provided.

[0077] The base station includes the automatic turntable system 10 described above.

[0078] Combined Figure 2 and Figure 3 , when the floor sweeper 10A switches to the cleaning posture through the automatic turntable system 10, the charging system and / or the cleaning system of the base station charge the floor sweeper 10A and / or clean the mop 30 of the floor sweeper 10A.

[0079] In Figure 2 , the charging positive and negative electrodes 29 and the mop 30 of the floor sweeper 10A are shown.

[0080] During the above implementation process, after the floor sweeper 10A rotates 180 degrees, the charging positive and negative electrodes 29 and the mop 30 of the floor sweeper 10A also rotate 180 degrees, so that charging and cleaning work can be carried out in the base station.

[0081] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications.
