The driving module 100 of the present invention realizes the first-stage deceleration by arranging the driving motor 211 to be axially connected with the speed reducer 212; the second-stage speed reduction is realized by the engagement of the spiral teeth 2131 of the worm rod piece 213 and the second gear 2211 of the large gear 221, and the self-locking function is realized; the flexible mounting of the drive module 100 is achieved by the first gear 2221 of the pinion gear 222 engaging with the rack 31.

As shown in fig. 6 to 8, the utility model discloses still provide an intelligent mobile terminal 500, this intelligent mobile terminal 500 includes terminal housing 400, flexible screen and drive module 100, and aforementioned embodiment is referred to drive module 100's concrete structure, because this intelligent mobile terminal 500 has adopted the whole technical scheme of aforementioned all embodiments, consequently has all beneficial effects that the technical scheme of aforementioned embodiment brought at least, and it is here no longer repeated.

In one embodiment, the driving module 100 is disposed in the terminal housing 400, the supporting frame 3 of the driving module 100 is slidably connected to the terminal housing 400, and the flexible screen is disposed on the supporting frame 3; the driving module 100 drives the supporting frame 3 to drive the flexible screen to contract the terminal housing 400 or extend out of the terminal housing 400.

It is understood that the terminal housing 400 may be a mobile phone housing, etc., and is not limited thereto. The installation shell 1 and the drive assembly 2 of the drive module 100 are installed on the terminal shell 400, the support frame 3 is located on one side of the installation shell 1, which faces away from the terminal shell 400, the flexible screen is located on one side of the support frame 3, which faces away from the terminal shell 400, so that the drive module 100 can drive the support frame 3 to drive the flexible screen to contract in the terminal shell 400 or stretch out of the terminal shell 400.

In one embodiment, one of the terminal housing 400 and the supporting frame 3 is provided with a guide rail 401, and the other is provided with a sliding member 402, and the sliding member 402 is slidably engaged with the guide rail 401.

As shown in fig. 6 to 8, the terminal housing 400 is provided with a guide rail 401, and the supporting frame 3 is provided with a sliding member 402, so that the sliding connection between the supporting frame 3 and the terminal housing 400 is realized by the sliding fit between the sliding member 402 and the guide rail 401, and the movement of the supporting frame 3 is guided. Of course, in other embodiments, the guide rail 401 may be disposed on the supporting frame 3, and the sliding member 402 may be disposed on the terminal housing 400, which is not limited herein. It is understood that the sliding connection between the supporting frame 3 and the terminal housing 400 may have other structures, and is not limited herein.

The above is only the optional embodiment of the present invention, and not therefore the limit to the patent scope of the present invention, all the concepts of the present invention utilize the equivalent structure transformation of the content of the specification and the attached drawings, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
