[0037] The technical solutions of the present application will be described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also belong to the protection scope of the present application.

[0038] The application will be further described in detail below with specific examples and in conjunction with the drawings.

[0039] Referring to Figures 1-3 The embodiment provides a folding air guide door 100, which comprises a main plate 110, a secondary plate 120, a motor 130 and a motor gland 140; the main plate 110 is rotationally connected with the secondary plate 120; the motor 130 is connected with the secondary plate 120 and is used for driving the secondary plate 120 to rotate relative to the main plate 110; the motor 130 is installed on the main plate 110; the motor gland 140 is matched with the main plate 110 and is used for pressing the motor 130 on the main plate 110.

[0040] The folding air guide door 100 provided by the embodiment is used for pressing the motor 130 for driving the secondary plate 120 to rotate on the main plate 110 by using the motor gland 140 after the motor 130 is installed on the main plate 110; after assembly is completed, the motor 130 can drive the secondary plate 120 to rotate relative to the main plate 110, so that the folding function of the folding air guide door 100 is realized.

[0041] It should be noted that the motor gland 140 can position the motor 130, so that the risk of loosening of the motor 130 can be greatly reduced, and the quality of the folding air guide door 100 is improved.

[0042] The recess 111 can be arranged on the main plate 110, the motor 130 is installed in the recess 111, and on this basis, the motor gland 140 is installed at the slot opening of the recess 111, so that the motor gland 140 is matched with the slot wall of the recess 111, the motor 130 is locked in the recess 111, and the recess 111 is beneficial to improving the positioning effect of the motor 130.

[0043] Referring to Figure 2 , Figure 4 and Figure 5 The hollow part 141 can be arranged on the motor gland 140, the hollow part 141 is arranged opposite to the motor 130, so that the setting of the hollow part 141 can increase the heat dissipation area of the motor 130 and improve the heat dissipation performance. The hollow part 141 can be a window arranged on the motor gland 140.

[0044] The first pressing plate portion 142 is clamped between one end of the motor 130 in the axial direction and the groove wall of the recess 111, and the second pressing plate portion 143 is clamped between the other end of the motor 130 in the axial direction and the groove wall of the recess 111. In this way, the volume of the recess 111 can be set to be larger, facilitating the installation of the motor 130 into the recess 111. After the motor 130 is installed into the recess 111, the first pressing plate portion 142 and the second pressing plate portion 143 are clamped into the gaps between the two ends of the motor 130 in the axial direction and the groove wall of the recess 111, thereby achieving the axial positioning of the motor 130.

[0045] Further, the side of at least one of the first pressing plate portion 142 and the second pressing plate portion 143, which faces away from the motor 130, is provided with a resilient buckle 145. Correspondingly, a clamping groove 112 is formed in the groove wall of the recess 111. When the motor cover 140 is installed, the resilient buckle 145 can be clamped into the clamping groove 112 in the groove wall of the recess 111. In this way, the positioning of the first pressing plate portion 142 and / or the second pressing plate portion 143 can be achieved, so that the first pressing plate portion 142 and the second pressing plate portion 143 can be smoothly installed in place and are not prone to loosening, thereby facilitating the improvement of the connection stability of the motor cover 140 and the main plate 110. In fact, the resilient buckle 145 provided on one of the first pressing plate portion 142 and the second pressing plate portion 143 can achieve a better positioning effect and facilitate assembly.

[0046] The third pressing plate portion 144 is further provided on the motor cover 140. The third pressing plate portion 144 abuts against the side wall of the motor 130 which faces away from the recess 111. In this way, the third pressing plate portion 144 can be used to press the motor 130 radially in the recess 111. Thus, the third pressing plate portion 144 can cooperate with the groove wall of the recess 111 to achieve the radial positioning of the motor 130.

[0047] Preferably, the side of the third pressing plate portion 144 which faces the motor 130 is shaped to be adapted to the side wall of the motor 130. In this way, the positioning 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 provided in the structure with an arc-shaped cross section.

[0048] Preferably, a first rib 114 is provided on the inner groove wall of the recess 111, and a second rib 147 is provided on the side of the first pressing plate portion 142, the second pressing plate portion 143 and the third pressing plate portion 144 of the motor cover 140 which faces the motor 130. The first rib 114 and the second rib 147 can be used to abut against the motor 130, thereby reducing the contact area of the recess 111, the motor cover 140 and the motor 130, and reducing the noise generated by the vibration and collision of the motor 130 during operation.

[0049] The recess 111 can have an arc-shaped slot wall and two plane slot walls, the two plane slot walls are respectively located at two sides of the arc-shaped slot wall and are perpendicular to the arc-shaped slot wall; the side wall of the motor 130 corresponds to the arc-shaped slot wall, the size of the arc-shaped slot wall can be set to be adapted to the size of the motor 130, the two ends of the motor 130 respectively correspond to the two plane slot walls, and the first pressing plate part 142 and the second pressing plate part 143 of the motor pressing cover 140 are clamped into the notches 113 respectively provided on the two plane slot walls. The second ribs 147 can be provided on the arc-shaped slot wall and the two plane slot walls of the recess 111.

[0050] The connecting part 146 can be further provided on the motor pressing cover 140, and the connecting part 146 is connected to the main plate 110 in a detachable manner, so that the motor pressing cover 140 and the main plate 110 are connected and fixed, and the motor pressing cover 140 can be detached from the main plate 110 as needed, improving the practicability. For example, when the pressing effect of the motor pressing cover 140 decreases or the motor 130 is damaged, the motor pressing cover 140 can be detached to repair or replace the motor pressing cover 140 or the motor 130.

[0051] Preferably, the connecting part 146 of the motor pressing cover 140 can be locked and fixed to the main plate 110 through a threaded connecting part 150, the threaded connecting part 150 can provide good locking reliability for the connecting part 146, and the threaded connecting part 150 is convenient to install and detach, so that the efficiency of disassembly and assembly can be improved. Specifically, the threaded connecting part 150 can be a screw, at this time, a threaded hole can be formed on the main plate 110, a through hole can be formed on the connecting part 146 of the motor pressing cover 140, and after the motor pressing cover 140 is installed to the position where the through hole on the connecting part 146 corresponds to the threaded hole on the main plate 110, the screw is passed through the through hole on the connecting part 146 and screwed into the threaded hole on the main plate 110, so that the connecting part 146 of the motor pressing cover 140 is locked and fixed to the main plate 110.

[0052] The rotating shaft 160 can be provided on the auxiliary plate 120 and rotationally matched with the main plate 110, so that the main plate 110 and the auxiliary plate 120 are rotationally matched through the rotating shaft 160; the motor shaft of the motor 130 is coaxially fixed with the rotating shaft 160, so that the motor 130 directly drives the auxiliary plate 120, the transmission is more stable, the torque is smaller, and the motor 130 can be miniaturized, so that the motor 130 can be smoothly installed into the recess 111 of the main plate 110.
