Through setting up first bolster 60 and second bolster 61, the connecting portion 45 cover of first bolster 60 is established on fastener 43 and wears to locate first fixed part 14 and second fixed part 59, the both ends of the protruding portion 62 of first bolster 60 respectively with the spacing portion 44 and the first fixed part 14 butt of fastener 43, the second bolster 61 cover is established on first bolster 60, and the both ends of second bolster 61 respectively with first fixed part 14 and second fixed part 59 butt for form elastic connection between drive assembly 10, shell 50 and the fastener 43, with the vibrations between buffering drive assembly 10 and the casing 52, reduce the influence of the vibrations that drive assembly 10 produced to reflector 200 adjustment accuracy, reduce the noise simultaneously.

Referring to fig. 2, the housing 50 is further provided with a positioning member 46, and the positioning member 46 is used for mounting and positioning the driving member 11. Alternatively, the positioning member 46 and the housing 50 may be of unitary construction. Optionally, the positioning member 46 is detachably connected to the housing 50, and the positioning member 46 and the housing 50 may be connected by plugging, screwing, and clamping, so that the positioning member 46 may be removed after the driving assembly 10 is installed, to reduce the weight of the product.

Through setting up setting element 46, setting element 46 and shell 50 can be integrated into one piece structure, also can be detachable connection, setting element 46 installs before drive assembly 10 to be convenient for carry out the location to drive assembly 10, make drive assembly 10 can be connected with shell 50 accuracy, guarantee that the position deviation that exists between drive element 11 and the reduction gears 21 is less than preset value, in order to reduce the wearing and tearing of drive element 11 and drive assembly 10, extension product life and stability.

In the description of the embodiments of the present utility model, it should be noted that, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like refer to the orientation or positional relationship described based on the drawings, which are merely for convenience of description and simplification of the description, and do not indicate or imply that the apparatus or element in question must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

The above disclosure is only a preferred embodiment of the present utility model, and it should be understood that the scope of the utility model is not limited thereto, but all or part of the procedures for implementing the above embodiments can be modified by one skilled in the art according to the scope of the appended claims.
