At the same time, it can also make up for the lack of fatherly and motherly love of left-behind children. It can not only realize the cross-time and space interaction between parents and children, but also serve as a playmate for children, bringing unique life experiences to children.

[0030] The accompanying robot in this embodiment includes a main body 10, a display screen 20 and a rotating assembly 30. The main body 10 has a supporting function. The display screen 20 is used for displaying images, and a camera is also provided on the display screen 20 to realize the monitoring function of the accompanying robot. The display screen 20 is rotatably connected to the main body 10; the rotating assembly 30 is used for connecting the display screen 20 and the main body 10 and driving the display screen 20 to rotate; the rotating assembly 30 includes a connecting member 31, a rotating shaft 32 and a fixing member 33. One end of the rotating shaft 32 is electrically connected to a motor 50, and the motor 50 drives the rotating shaft 32 to rotate; a limiting portion 321 is provided on the rotating shaft 32, and the limiting portion 321 extends outward along the circumferential direction of the rotating shaft 32. The limiting portion 321 is used for limiting the mounting portion 21, the connecting member 31 and other structural members; the fixing member 33 is detachably connected to the rotating shaft 32, so that the fixing member 33 and the limiting portion 321 jointly press and fix the structural members located between the fixing member 33 and the limiting portion 321; one ends of the mounting portion 21 and the connecting member 31 are both sleeved outside the rotating shaft 32, and the mounting portion 21 and the connecting member 31 are both fixed between the limiting portion 321 and the fixing member 33. The other end of the mounting portion 21 is fixedly connected to the display screen 20, and the other end of the connecting member 31 is fixedly connected to the main body 10. The connecting member 31 is used for connecting the rotating shaft 32 and the main body 10. The end of the connecting member 31 away from the rotating shaft 32 and the end of the mounting portion 21 away from the rotating shaft 32 extend in opposite directions, so that the display screen 20 is rotatably connected to the main body 10.

[0031] When the motor 50 is started, the rotating shaft 32 rotates clockwise or counterclockwise, thereby driving the mounting portion 21 to rotate on the horizontal plane, and finally causing the display screen 20 to rotate, so as to improve the flexibility of the display screen 20.

[0032] In this application, by providing the rotation assembly 30 between the display screen 20 and the main body 10, both the connecting member 31 and the mounting portion 21 of the display screen 20 are sleeved on the rotating shaft 32, and both the connecting member 31 and the mounting portion 21 are press-fitted and fixed on the rotating shaft 32 by the limiting portion 321 and the fixing member 33. The connecting member 31 fixes the rotating shaft 32 on the main body 10. When the rotating shaft 32 rotates, the display screen 20 rotates along with the rotation of the rotating shaft 32, so as to improve the stability and accuracy of the rotation of the display screen 20.

[0033] More specifically, the overall shape of the companion robot in this embodiment is a pea-shaped intelligent companion robot, thereby increasing the interest of the companion robot.

[0034] In one embodiment, referring to Figures 1 to 3 As shown, the connecting member 31 is located on the side of the mounting portion 21 close to the limiting portion 321. The rotating shaft assembly 30 further includes a key-fitting piece 34 sleeved outside the rotating shaft 32, and the key-fitting piece 34 is located between the connecting member 31 and the limiting portion 321. Specifically, both the connecting member 31 and the mounting portion 21 are only sleeved outside the rotating shaft 32, and the connecting member 31 is located on the side of the mounting portion 21 close to the limiting portion 321. The rotating shaft assembly 30 further includes a key-fitting piece 34 sleeved outside the rotating shaft 32, and the key-fitting piece 34 is located between the connecting member 31 and the limiting portion 321. The fixing member 33 and the limiting portion 321 press-fit the mounting portion 21, the connecting member 31 and the key-fitting piece 34 on the rotating shaft 32. When the rotating shaft 32 rotates, the key-fitting piece 34 can output torque more stably, thereby further improving the stability of the rotation of the display screen 20.

[0035] In a specific embodiment, referring to Figures 1 to 3As shown, the rotating shaft assembly 30 further includes a gasket 35. The gasket 35 is sleeved on the outer side of the rotating shaft 32, and the gasket 35 is located between the key fitting piece 34 and the limiting portion 321.

The gasket 35, the key fitting piece 34, the connecting piece 31, and the mounting portion 21 are all pressed and fixed on the rotating shaft 32 by the limiting portion 321 and the fixing piece 33. The gasket 35 increases the friction between the key fitting piece 34 and the limiting portion 321, thereby preventing the key fitting piece 34 and the limiting portion 321 from loosening, resulting in the assembly of the structural members of the rotating shaft assembly 30 becoming loose, affecting the rotation of the mounting portion 21, and further affecting the rotation of the display screen 20. By increasing the friction between the key fitting piece 34 and the limiting portion 321, the structural stability of the rotating shaft assembly 30 is improved, making the rotation of the display screen 20 more stable.

[0036] In one embodiment, referring to Figures 1 to 3As shown, the rotating shaft assembly 30 further includes two friction members 36 sleeved outside the rotating shaft 32.

The two friction members 36 are respectively located outside the connecting member 31 and the mounting portion 21. Both ends of the receiving groove 361 are provided with the upper groove wall 3611 and the lower groove wall 3612. When assembling the rotating shaft assembly 30, the connecting member 31 and the mounting portion 21 are respectively installed in the receiving grooves 361 of the two friction members 36, and the upper and lower sides of the connecting member 31 and the upper and lower sides of the mounting portion 21 are respectively abutted against the upper groove wall 3611 and the lower groove wall 3612, so that the two friction members 36 respectively wrap the upper and lower sides of the connecting member 31 and the mounting portion 21, thereby increasing the friction between the connecting member 31 and the mounting portion 21 and other structural members. Thus, a certain rotation angle of the mounting portion 21 is kept unchanged through the friction member 36, so that the display screen 20 is kept in a certain working state, the rotation accuracy and stability of the display screen 20 are improved, and the structural strength of the rotating shaft assembly 30 is also improved.

[0037] In a specific embodiment, referring to Figures 1 to 3 As shown, the fixing member 33 is a nut.

Specifically, the connecting member 31 includes a first connecting section 311 and a second connecting section 312, and the first connecting section 311 and the second connecting section 312 are perpendicularly connected, that is, the connecting member 31 has an "L" - shaped structure. The first connecting section 311 is completely closely attached to one side of the main body 10 and fixedly connected to the main body 10. The second connecting section 312 extends perpendicularly to the main body 10 in the direction of the rotating shaft 32. One end of the second connecting section 312 is sleeved on the outer side of the rotating shaft 32, thereby realizing the connection between the rotating shaft 32 and the main body 10. The first connecting section 311 and the second connecting section 312 are fixed, and the rotating shaft 32 can rotate. The "L" - shaped connecting member 31 transmits torque to the display screen 20, thereby realizing the rotation of the display screen 20. The main body 10 does not rotate. The structure of the connecting member 31 is simple and the connection stability is high.
