Such door handles require a reserved position for the door handle on the vehicle door and a recess is designed at the same time, which makes the streamline design of the vehicle body have great limitations, and wind resistance and noise will be generated during driving. With the improvement of the vehicle structure, hidden door handles have emerged. This kind of door handle retracts into the door when not in use and is not easy to see. When it is needed, it extends out according to the control instruction for convenient door opening. Compared with the traditional straight-pull door handle, the hidden door handle makes the overall shape of the vehicle body more streamlined and beautiful, and at the same time reduces wind resistance.

Detailed Embodiments
[0017] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.
[0018] Embodiment: As Figures 1-3 shown, a lifting platform with a guiding function for a concealed handle of the present utility model includes a positioning seat 1 and a lifting table 2. The surface of the lifting table 2 is used for installing a handle; and a vertical downward guiding column 3 and several limiting columns 4 are provided at the bottom of the lifting table 2, and a through hole 5 for the guiding column 3 and the limiting column 4 to pass through is provided on the positioning seat 1. A straight rack 6 is vertically provided on the side wall of the guiding column 3, and a receiving groove 7 for receiving the straight rack 6 is provided on the guiding column 3. A gear 8 meshing with the straight rack 6 is provided on the positioning seat 1, and a driving motor 9 for driving the gear 8 to rotate is fixed on the positioning seat 1.
