PREFERRED EMBODIMENT

[0018] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0019] Example: Figures 1-4 As shown, this utility model discloses a vertically driven platform with a lifting motor, including a lifting platform 1 and a positioning frame 2. The bottom of the lifting platform 1 is provided with a fixed housing 3. The fixed housing 3 is provided with a vertically downward lead screw 4 and multiple guide posts 5. The fixed housing 3 is also provided with multiple guide sleeves 6 for inserting the guide posts 5. The positioning frame 2 is also fixed with a fixing nut 7, which meshes with the lead screw 4. The fixed housing 3 is provided with a drive motor 8 that drives the lead screw 4 to rotate. The bottom of the fixed housing 3 is provided with an insertion cavity 9 for inserting the outer end of the positioning frame 2. This invention houses the drive motor 8 and the lead screw 4 within the mounting housing formed by the positioning frame 2 and the retaining housing. This effectively reduces the overall lateral volume, ensuring that it does not occupy excessive space when installed inside the car door and does not adversely affect the installation of other components inside the car door. During operation, the drive motor 8 rotates the lead screw 4. Since the fixing nut 7 is fixed inside the housing 10, the lead screw 4 and the fixing nut 7 undergo relative displacement, thereby enabling the extension and retraction of the lifting platform 1. Because the handle is mounted on the lifting platform 1, it can be retracted and hidden. This invention is characterized by its simple structure and ease of assembly.

[0020] The positioning frame 2 is provided with an inwardly recessed storage cavity 10 for storing the fixing nut 7. A positioning post 12 for positioning the fixing nut 7 is installed in the storage cavity 10, which facilitates fixing the fixing nut. The positioning post 12 is provided with a through hole for the lead screw 4 to pass through.

[0021] The positioning post 12 is provided with a positioning edge 13, which is fixed to the positioning frame 2 by bolts. The positioning frame 2 is provided with a storage groove 17 for storing the positioning edge, which facilitates the fixing of the positioning post and prevents the end of the positioning post from protruding outside the fixing housing and abutting against the side wall of the door.

[0022] The positioning frame 2 includes an upper frame 14 and a lower frame 15. The guide sleeve 6 is provided on the upper frame 14, and the lower frame 15 is also provided with a telescopic cavity 16 for the guide post 5 to extend and retract. The fixing nut 7 is fixed on the lower frame 15. This facilitates the installation of the guide post and the guide sleeve, as well as the installation and disassembly of the whole.

[0023] Working principle: drive motor 8, screw rod 4 are all received in the installation shell formed by the positioning frame 2 and the retaining shell, which effectively reduces the overall transverse volume, does not occupy too much volume when installed in the door, does not cause adverse effects on the installation of other components in the door; wherein the utility model discloses when working through drive motor 8 drives screw rod 4 to rotate, because fixed nut 7 is fixed in the storage cavity 10, so that screw rod 4 and fixed nut 7 relatively displace, and the telescopic of lifting platform 1 is realized, because handle is installed on lifting platform 1, so handle can be retracted and hidden, and has the characteristics of simple structure and easy assembly.

[0024] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features. Any modification, equivalent replacement, improvement etc. within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
