[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0021] A door glass lifting mechanism includes a door glass body 1. Y-direction fixing members 11 are respectively clamped at the lower left and lower right of the door glass body 1. A glass fixing member 3 is provided at the bottom position of the door glass body 1. A slide rail 802 is fixedly connected to the lower right position of the glass fixing member 3. A lifting platform 8 is provided directly below the slide rail 802. Slide blocks 803 are respectively fixedly connected to the upper right end and the lower right end of the lifting platform 8. The slide blocks 803 are slidably connected with the slide rail 802. A fixed bracket 701 is fixedly connected to the bottom end of the glass fixing member 3 located below the lifting platform 8. A coupling 6 is provided at the lower inner side position of the fixed bracket 701. One end of the coupling 6 is connected to a lead screw 4. A lead screw transmission member 5 is threadedly connected to the outside of the lead screw 4. A transmission ejector rod 501 is fixedly connected to one side of the lead screw transmission member 5.

[0022] Such as Figure 1 and Figure 2As shown, on the side of the Y-direction fixing member 11 close to the vehicle door glass body 1, there are respectively fixedly connected with supporting blocks 201. On the side of the supporting block 201 away from the Y-direction fixing member 11, there is a rotatable connection with a guide rail universal wheel 2. The wheel surface of the guide rail universal wheel 2 is in abutting contact with the outer surface of the vehicle door glass body 1. Since the vehicle door glass body 1 is in abutting contact with the guide rail universal wheel 2, when the vehicle door glass body 1 realizes a stable lifting operation, the 4 groups of front and rear guide rail universal wheels 2 will rotate relative to each other due to the upward transmission of the glass, ensuring that the glass is not prone to jamming during the lifting process; at the bottom end of the Y-direction fixing member 11, there is a fixedly connected X-direction fixing member 10. On both sides of the glass fixing member 3 located below the lifting platform 8, there are respectively fixedly connected with Z-direction fixing members 9. There are 2 X-direction fixing members 10 in total. At the top end of the glass fixing member 3 located below the lifting platform 8, there is fixedly installed an optoelectronic sensor 801. By respectively arranging a group of X-direction fixing members 10 and a group of Z-direction fixing members 9, this structural arrangement mainly plays a role in assisting the universal wheel structure and the lifting structure to quickly transfer the vehicle door.

[0023] As Figure 1 and Figure 3 shown, at the middle position of the bottom end of the glass fixing member 3 located below the lifting platform 8, there is a fixedly connected transmission clamping seat 502. There is a rotatable connection between the transmission clamping seat 502 and the lead screw 4. On one side of the transmission clamping seat 502, there is a fixedly connected side supporting rod 503. The left lower end of the side supporting rod 503 is sleeved outside the lead screw 4. When the lead screw 4 rotates to make the lead screw transmission member 5 perform an up-and-down lifting action, the transmission clamping seat 502 and the side supporting rod 503 will provide a connection limiting function from one end position of the lead screw 4.

[0024] As Figure 1 , Figure 4 and Figure 5 shown, at the bottom end of the fixed bracket 701, there is a fixedly connected DC motor 7. The output end of the DC motor 7 penetrates through the fixed bracket 701 and is connected with the coupling 6. The transmission ejector rod 501 penetrates through the top end of the glass fixing member 3 located below the lifting platform 8. One end of the transmission ejector rod 501 is fixedly connected with one end of the glass fixing member 3 located above the lifting platform 8. There is a rotatable connection between the glass fixing member 3 and the lifting platform 8. When the lead screw 4 rotates to make the lead screw transmission member 5 perform an up-and-down lifting action, the transmission ejector rod 501 will jack up the glass fixing member 3 located above the lifting platform 8, thereby enabling the lifting platform 8 to be folded and unfolded upward, and thus realizing the jacking of the vehicle door glass body 1.

[0025] Working process: The electric energy required when the lifting mechanism in the present utility model starts to operate comes from the vehicle power supply module. When it is necessary to perform the lifting adjustment operation on the door glass body 1 during the driving of the vehicle, first, the entire lifting mechanism can be installed on the door by means of screw fixation, respectively installing the Z-direction fixing member 9 and the X-direction fixing member 10 on the door, and controlling the DC motor 7 to be powered on and started, so that it can drive the lead screw 4 to rotate through the coupling 6 under the connection action of the transmission clamping seat 502, the side support rod 503 and the fixed bracket 701, and push the lifting platform 8 to rise through the lead screw transmission member 5 and the transmission ejector rod 501. The glass fixing member 3 and the door glass body 1 rise as a whole, and the setting of the guide rail universal wheel 2 in the X direction of the glass fixed in the Y direction can make the glass lift stably without jamming.

[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
