[0038] The present invention is further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0039] See also Figure 1-Figure 3 The present embodiment provides a folding air guide door 100, which includes a main board 110, a sub-board 120, a motor 130 and a motor pressure cover 140; the main board 110 is rotatably connected to the sub-board 120, and the motor 130 is connected to the sub-board 120 to drive the sub-board 120 to rotate relative to the main board 110; the motor 130 is installed on the main board 110, and the motor pressure cover 140 cooperates with the main board 110 to press the motor 130 against the main board 110.

[0040] The folding air guide door 100 provided in this embodiment, after the motor 130 is installed on the main board 110, the motor 130 used to drive the sub-board 120 to rotate is pressed onto the main board 110 using the motor pressure cover 140. After the assembly is completed, the motor 130 is started to drive the sub-board 120 to rotate relative to the main board 110, so as to realize the folding function of the folding air guide door 100.

[0041] It should be noted that the motor pressure cover 140 can position the motor 130 , which can greatly reduce the risk of the motor 130 loosening and improve the quality of the folding air guide door 100 .

[0042] A groove 111 can be set on the main board 110, and the motor 130 can be installed in the groove 111. On this basis, the motor cover 140 is installed at the notch of the groove 111, so that the motor cover 140 can cooperate with the groove wall of the groove 111 to lock the motor 130 in the groove 111. The setting of the groove 111 is conducive to improving the positioning effect of the motor 130.

[0043] See also Figure 2 , Figure 4 and Figure 5 A hollow portion 141 may be provided on the motor gland 140, and the hollow portion 141 is arranged opposite to the motor 130. Thus, the hollow portion 141 can increase the heat dissipation area of ​​the motor 130 and improve the heat dissipation performance. The hollow portion 141 may be a window provided on the motor gland 140.

[0044] A first pressing plate portion 142 and a second pressing plate portion 143 may also be provided on the motor cover 140, and the first pressing plate portion 142 is clamped between one axial end of the motor 130 and the groove wall of the groove 111, and the second pressing plate portion 143 is clamped between the other axial end of the motor 130 and the groove wall of the groove 111. In this way, the volume of the groove 111 can be set larger to facilitate the installation of the motor 130 into the groove 111. After the motor 130 is installed in the groove 111, the first pressing plate portion 142 and the second pressing plate portion 143 are respectively clamped into the gaps between the two axial ends of the motor 130 and the groove wall of the groove 111, so as to achieve axial limitation of the motor 130.

[0045] Further, a snap button 145 may be provided on the side of at least one of the first pressing plate portion 142 and the second pressing plate portion 143 facing away from the motor 130. Accordingly, a card slot 112 is provided on the groove wall of the groove 111. When the motor gland 140 is installed, the snap button 145 may be inserted into the card slot 112 on the groove wall of the groove 111. In this way, the first pressing plate portion 142 and / or the second pressing plate portion 143 may be positioned, so that the first pressing plate portion 142 and the second pressing plate portion 143 may be smoothly installed in place and not easily loosened, which is beneficial to improving the connection stability between the motor gland 140 and the main board 110. In fact, by providing the snap button 145 on one of the first pressing plate portion 142 and the second pressing plate portion 143, a better positioning effect can be achieved and assembly is facilitated.

[0046] A third pressure plate portion 144 may also be provided on the motor cover 140, and the third pressure plate portion 144 is abutted against the side wall of the motor 130 facing away from the groove 111. In this way, the third pressure plate portion 144 can be used to radially press the motor 130 into the groove 111. In this way, the third pressure plate portion 144 can cooperate with the groove wall of the groove 111 to achieve radial limitation of the motor 130.

[0047] The shape of the side of the third pressing plate portion 144 facing the motor 130 is preferably set to be compatible with the side wall of the motor 130, so that the limiting effect of the third pressing plate portion 144 on the motor 130 can be improved. The side wall of the motor 130 is generally cylindrical, so the third pressing plate portion 144 can be set to a structure with an arc cross section.

[0048] Preferably, a first rib 114 can be provided on the inner groove wall of the groove 111, and a second rib 147 can be provided on the side of the first pressure plate portion 142, the second pressure plate portion 143 and the third pressure plate portion 144 of the motor pressure cover 140 facing the motor 130, so that the first rib 114 and the second rib 147 can be used to abut the motor 130, thereby reducing the contact area between the groove 111, the motor pressure cover 140 and the motor 130, and reducing the noise generated by vibration and collision when the motor 130 is running.

[0049] The groove 111 may have an arcuate groove wall and two plane groove walls, the two plane groove walls are respectively located on both sides of the arcuate groove wall and are perpendicular to the arcuate groove wall; the side wall of the motor 130 corresponds to the arcuate groove wall, the size of the arcuate groove wall can be set to be adapted to the size of the motor 130, the two ends of the motor 130 correspond to the two plane groove walls, and the two plane groove walls are respectively provided with notches 113, which can be used for the first pressing plate part 142 and the second pressing plate part 143 of the motor gland 140 to be inserted. The second rib 147 can be set on the arcuate groove wall and the two plane groove walls of the groove 111.

[0050] A connecting portion 146 may be further provided on the motor gland 140, and the connecting portion 146 is connected to the main board 110 in a detachable manner, so that the motor gland 140 and the main board 110 can be connected and fixed, and the motor gland 140 can be removed from the main board 110 as needed, thereby improving practicality. For example, when the pressing effect of the motor gland 140 decreases or the motor 130 is damaged, the motor gland 140 can be removed to repair or replace the motor gland 140 or the motor 130.

[0051] Preferably, the connection part 146 of the motor gland 140 can be locked and fixed to the main board 110 through the threaded connector 150. The threaded connector 150 can provide good locking reliability for the connection part 146, and the threaded connector 150 is relatively convenient to install and remove, which can improve the efficiency of assembly and disassembly. Specifically, the threaded connector 150 can be a screw. In this case, a threaded hole can be opened on the main board 110, and a through hole can be opened in the connection part 146 of the motor gland 140. After the motor gland 140 is installed to the position where the through hole on the connection part 146 is opposite to the threaded hole on the main board 110, the screw is passed through the through hole on the connection part 146 and screwed into the threaded hole on the main board 110, so that the connection part 146 of the motor gland 140 can be locked and fixed to the main board 110.

[0052] A rotating shaft 160 can be set on the sub-plate 120, and the rotating shaft 160 can be rotatably matched with the main plate 110. In this way, the main plate 110 and the sub-plate 120 can be rotated and matched through the rotating shaft 160; the motor shaft of the motor 130 is coaxially fixed with the rotating shaft 160. In this way, the motor 130 can directly drive the sub-plate 120, and the transmission is more stable and the torque is smaller. In addition, the motor 130 can be miniaturized, which is convenient for smoothly installing the motor 130 into the groove 111 of the main plate 110.
