[0024] For the sake of clearly describing the utility model, now further detailed description is combined with the drawings.

[0025] Example 1

[0026] As Figures 1-5 shown, a kind of module lifter fixing structure part, including: base 2, first buckle 5, second buckle 6 and fixed screw 3.

[0027] The base 2 is provided with a center hole 22; the first clamping buckle 5 is at least two, which is fixedly connected with the base 2; the second clamping buckle 6 is at least two, which is fixedly connected with the base 2; the fixing screw 3 includes a screw rod 31 and a nut 32.

[0028] Among them, the first clamping buckle 5 and the second clamping buckle 6 are distributed on the concentric circle of the center hole 22, the height of the first clamping buckle 5 is less than the height of the second clamping buckle 6, and the radius of the nut 32 is greater than the distance from the hook part of the first clamping buckle 5 and the hook part of the second clamping buckle 6 to the axis of the center hole 22.

[0029] The first clamping buckle 5 and the second clamping buckle 6 are arranged in an alternating circular array.

[0030] The bottom surface of the base 2 is provided with a sealing protrusion 21.

[0031] The hook part is provided with a transition inclined surface.

[0032] As shown in the figure, the base 2 is arranged close to the edge of the module lifter, and "X" is the arrangement point of the fixing structure. Figure 8

[0033] The flange hole 11 of the door panel 1 on the vehicle door is threaded by the fixing screw 3, and then the fixing structure is fixed to the door panel 1 by tightening the fixing screw 3.

[0034] The fixing screw 3 needs to be pre-assembled to the fixing structure of the module lifter, the first clamping buckle 5 on the fixing structure can limit the movement of the fixing screw 3 to one side of the door panel 1, and the second clamping buckle 6 on the fixing structure can limit the movement of the fixing screw 3 to the side away from the door panel 1, so as to achieve the pre-positioning effect of the fixing structure on the fixing screw 3. Ensure that the fixing screw 3 is supplied to the automobile assembly line together with the module lifter.

[0035] When tightening the fixing screw 3, the fixing screw 3 is pushed to move to the side of the door panel 1 by the tightening tool, and then the fixing screw 3 is tightened, so as to fix the fixing structure to the door panel 1.
