In the single motor driving scene, the driving motor needs to drive multiple connecting rod mechanisms to move, so the fixing mode of the driving motor is very important. In the prior art, in order to fix the driving motor, the grille frame of the air inlet grille module is usually set to be relatively complex, which is difficult to process, and needs to be optimized.

[0049] The main purpose of the present application is to provide a driving mechanism, an air inlet grille module and a vehicle, which aims to optimize the fixing mode of the existing driving motor.

[0050] Please refer to Figures 1 to 2The utility model also proposes a drive mechanism 10, drive mechanism 10 includes drive motor 11 and two drive main shafts 12, drive motor 11 is detachably installed on the grille frame 30 through mounting seat 20.

[0052] It can be understood that in the fixing scheme of drive motor 11, not only drive motor 11 needs to be fixed, but also some fixing structures need to be used; moreover, drive motor 11 needs to be connected with control cable, and some holes need to be installed to pass through cable; in addition, drive motor 11 is drivingly connected with two drive main shafts 12, and how to set drive motor 11 also needs to consider the setting mode of two drive main shafts 12 and the like, which are all aspects that need to be considered in the fixing scheme of drive motor 11.

[0053] In the embodiment of the utility model, the structure of some fixing schemes above is concentrated on mounting seat 20, and mounting seat 20 is relatively small in size relative to grille frame 30, so that complex structures can be conveniently processed. Only some simple connecting and cooperating structures need to be arranged on grille frame 30, and the connection between grille frame 30 and mounting seat 20 can be realized, so that the processing is greatly simplified.

[0054] During assembly, drive motor 11 and two drive main shafts 12 are assembled, then are integrally assembled to mounting seat 20, then mounting seat 20 is assembled to grille frame 30, and the assembly can be completed, so that the assembly efficiency is greatly improved.
