This structural arrangement can reduce the thickness of the mounting bracket 160 and the end cover 175 after assembling, thereby facilitating the lightweight and thin design of the mobile terminal 10 . The setting of the baffle 177 can prevent the movement of the end cover 175 in the thickness direction of the mobile terminal 10 during the rotation process, thereby preventing the mounting seat 200 from moving in the thickness direction of the mobile terminal 10, thereby improving the stability of the rotation of the mounting seat 200. sex. Further, in some embodiments, after the end cover 175 , the mounting bracket 160 and the motor 180 are assembled into an assembly, the thickness thereof is less than or equal to the thickness of the mounting seat 200 . Assembly of the mount 200. For example, after assembling the end cover 175 , the mounting seat 200 , the motor 180 and the mounting seat 200 , they can be inserted into the mounting slot 101 from the outside of the frame 123 , and then the mounting frame 160 and the middle plate 121 can be fixed.

Further, referring to FIGS. 20 , 21 and 22 , the mounting bracket 160 includes a collar 167 , the collar 167 is sleeved on the outer circumference of the boss 161 , and the collar 167 is provided with a protrusion 168 on the side away from the groove 162 , the convex Raise 168 is used to support end cap 175 during rotation of end cap 175 . Further, the protrusion 168 is integrally formed on the collar 167, and the protrusion 168 is in the shape of a closed ring in the circumferential direction. Referring to FIG. 11 , the protrusion 168 has a second end 168 a for supporting the end cap 175 , and the cross-sectional profile of the second end 168 a is arc-shaped. The arrangement of the protrusions 168 can support the base body 220 during the rotation of the mounting base 200 relative to the main body 100 , so that the base body 220 can rotate stably and avoid generation between the base body 220 and the boss 161 of the mounting frame 160 . high frictional resistance. The collar 167 can be made of a wear-resistant and relatively high-strength material, such as stainless steel or ceramics, to form an effective support for the end cover 175 and facilitate the realization of a thin and light design of the mobile terminal 10 . Of course, the collar 167 can be integrally formed with the boss 161 .

In some embodiments, the mounting base 200 can maintain a communication connection with the circuit board of the body 100 during the rotation process relative to the body 100 . For example, the body 100 may include a flexible circuit board or a coaxial cable, and the camera module 210 of the mounting base 200 , the fan 230 and other electronic components can be communicatively connected to the circuit board of the main body 100 through a flexible circuit board or a coaxial cable. In some embodiments, the structure of metal contacts can also be used, and the communication connection between the mounting base 200 and the circuit board of the main body 100 is realized through the metal contact structure when the camera module 210 is exposed and positioned, so that the camera module of the mounting base 200 is Group 210 or other electronic components can be used normally.
