[0029] To describe in detail the technical content, achieved objectives and effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the drawings.

[0030] Please refer to Figure 1 and Figure 5As shown, the present utility model designs a mobile pet companion robot, which can be specifically used to walk indoors at home and observe the living conditions of pets. The mobile pet companion robot specifically includes: a housing 1 and a walking device 2, and the walking device 2 is detachably arranged at the bottom end of the housing 1, so that when the walking device 2 is affected by hair or other foreign objects and its movement is restricted, the user can detach the walking device 2 from the housing 1 and clean it, thus simplifying the cleaning process and preventing the cleaning water from entering the circuit part inside the housing 1, optimizing the user experience.

[0031] Among them, referring to Figure 1 and Figure 2 As shown, in this embodiment, considering aesthetics, the housing 1 of the mobile household robot can be integrally spherical, with a more beautiful and cute shape, and at the same time it is easier to avoid obstacles. And, in order to further improve aesthetics and passability, a groove 11 is also provided at the bottom of the housing 1, and the walking device 2 can be specifically arranged in the groove 11 to present a posture of being partially embedded in the housing 1; among them, in order to ensure that the walking device 2 can normally drive the robot to walk, at least part of the walking device 2 needs to be controlled to extend out of the groove 11 to contact the ground.

[0032] Referring to Figures 3 - 5 , in actual application, the walking device 2 specifically includes: a motor compartment and two drive wheel sets. The two drive wheel sets are respectively arranged on the left and right sides of the motor compartment, and both of these two drive wheel sets include a crawler 23 and two drive wheels, and these two drive wheels are respectively a first drive wheel 21 and a second drive wheel 22. Among them, in this embodiment, in order to enhance the passability and reliability of the walking device 2 when facing obstacles and avoid restricted movement, the outer shapes of the first drive wheel 21 and the second drive wheel 22 are not the same, and the crawler 23 is used to surround the first drive wheel 21 and the second drive wheel 22 of the drive wheel set and form a wheeled structure.

[0033] It should be noted that as Figure 4 and Figure 5As shown in the figure, in order to ensure that the above-mentioned crawler 23 can effectively surround the first driving wheel 21 and the second driving wheel 22 of the driving wheel set and is not easily loosened, in this embodiment, a tooth groove 211 and an annular groove 212 are provided on the outer peripheral wall of the first driving wheel 21 of the above-mentioned driving wheel set, and the annular groove 212 is arranged around the outer peripheral wall of the first driving wheel 21; moreover, a convex tooth 231 and an annular rib 232 are provided on the inner peripheral wall of the above-mentioned crawler 23, and the convex tooth 231 of the above-mentioned crawler 23 can be correspondingly meshed and matched with the tooth groove 211 on the first driving wheel 21, and the annular rib 232 of the above-mentioned crawler 23 can be correspondingly meshed and matched with the annular groove 212 on the first driving wheel 21. Based on this setting, the mutual matching relationship between the crawler 23 and the first driving wheel 21 can be restricted, and the crawler 23 can be prevented from loosening from the first driving wheel 21; at the same time, it is also convenient for the user to disassemble the crawler 23 from the outer peripheral wall of the first driving wheel 21, reducing the disassembly difficulty of the crawler 23 and facilitating subsequent cleaning or replacement.

[0034] Correspondingly, in this embodiment, in order to optimize the matching effect between the above-mentioned crawler 23 and the first driving wheel 21, in actual setting, a plurality of tooth grooves 211 are provided on the outer peripheral wall of the above-mentioned first driving wheel 21, and these tooth grooves 211 are arranged at equal intervals around the outer peripheral wall of the first driving wheel 21; moreover, the above-mentioned tooth grooves 211 are arranged along the extension direction of the central axis of the first driving wheel 21, and the annular groove 212 on the outer peripheral wall of the above-mentioned first driving wheel 21 extends at a 90° angle to the above-mentioned tooth grooves 211 on the outer peripheral wall of the first driving wheel 21. Among them, in this embodiment, the above-mentioned annular groove 212 is arranged on the central axis in the thickness direction of the outer peripheral wall of the first driving wheel 21 to ensure uniform force application.

[0035] In addition, in order to improve the installation effect between the above-mentioned first driving wheel 21 and the crawler 23 and facilitate the user to reinstall after disassembly, in this embodiment, the annular groove 212 of the above-mentioned first driving wheel 21 is specifically arranged to be respectively and communicatively connected with a plurality of tooth grooves 211. The user only needs to snap the convex tooth 231 on the crawler 23 into the corresponding tooth groove 211 of the first driving wheel 21, and the matching relationship between the above-mentioned annular rib 232 and the annular rib 232 on the outer peripheral wall of the first driving wheel 21 can be indirectly completed.

[0036] In addition, in this embodiment, the tooth groove 211 of the above-mentioned first driving wheel 21 is specifically set as a flat-topped conical tooth groove 211, and the cross-sectional area of one end of the tooth groove 211 away from the central axis direction of the first driving wheel 21 is larger than the cross-sectional area of the other end of the tooth groove 211 close to the central axis direction of the first driving wheel 21. The reason for using the flat-topped conical tooth groove 211 to match with the convex tooth 231 of the crawler 23 is to strengthen the meshing and matching effect between the two, so that when the robot walks obliquely on one side, the convex tooth 231 on the crawler 23 will not easily loosen from the flat-topped conical tooth groove 211 on the first driving wheel 21.

[0037] Accordingly, as Figure 4 shown, in order to prevent the crawler 23 from easily coming off the second drive wheel 22, in this embodiment, an annular accommodation groove 221 is further provided on the outer peripheral wall of the second drive wheel 22. The annular accommodation groove 221 is arranged around the second drive wheel 22, and both sides of the annular accommodation groove 221 have retaining edges. At least a part of the crawler 23 can be correspondingly wound around the annular accommodation groove 221 of the second drive wheel 22 to prevent the crawler 23 from laterally displacing and detaching from the second drive wheel 22. At the same time, this matching form between the crawler 23 and the second drive wheel 22 is also a matching form that is easy to disassemble. The user can also easily disassemble the crawler 23 from the second drive wheel 22 and perform cleaning or replacement.

[0038] Further referring to the above Figure 4 It can be seen that in this embodiment, although the structures of the above-mentioned first drive wheel 21 and second drive wheel 22 are significantly different, the outer contour diameters of the above-mentioned first drive wheel 21 and second drive wheel 22 are still controlled to be exactly the same, so as to obtain better balance when the crawler 23 is sleeved on the two drive wheels to form a wheeled structure and ensure that it is not easy to roll over.

[0039] In summary, it can be seen that the mobile pet companion robot designed by the present utility model has a simple structure, low cost, and can achieve the effect that the crawler 23 will not come off the first drive wheel 21 or the second drive wheel 22 when the robot walks with one side tilted. It has better stability, higher reliability, better user experience, and has good promotion prospects and application value.
