[0037] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Now, in conjunction with the drawings, the preferred embodiments of the present invention will be described in detail.

[0038] The embodiment of the present invention provides an air guiding device 1000, which is applied to the air outlet of an automobile air conditioner. As Figures 1 to 4 shown, the air guiding device 1000 includes a housing 100 and a follower fan 200. The housing 100 has an inner cavity 110 inside. The housing 100 is also provided with an air inlet 120 and a first air outlet 130 that communicate with the inner cavity 110. The air inlet 120 is used for air flow to blow in. The first air outlet 130 is arranged around the air inlet 120. The air outlet direction of the first air outlet 130 is perpendicular to the air inlet direction of the air inlet 120 (as Figure 2 shown by the X direction in

[0039] ); the follower fan 200 is installed in the inner cavity 110 and rotatably connected to the housing 100; the rotation axis of the follower fan 200 is consistent with the air inlet direction; wherein, the follower fan 200 is used to guide the air flow entering from the air inlet 120 to be blown out from the first air outlet 130. The air guiding device 1000 of the present application can diffuse the air flow blown out from the middle air outlet of the automobile, making the temperature reduction effect in the vehicle more uniform.

[0040] Specifically, the air flow blows into the air inlet 120 and enters the inner cavity 110, and then drives the follower fan 200 to rotate. While the follower fan 200 rotates, it changes the flow direction of the air flow, so that the air flow is blown out from the first air outlet 130. And because the first air outlet 130 is arranged around the air inlet 120, while the follower fan 200 changes the flow direction of the air flow, it will also rotate and diffuse the air flow around, so as to more effectively cover the entire vehicle interior space and improve the temperature reduction effect inside the automobile. In addition, since the air guiding device 1000 can disperse the air blown out by the automobile air conditioner, it can avoid the air directly blowing on the user, thus effectively reducing the discomfort of the user.

[0041] Refer to Figure 5 And Figure 6, in the present application, the shape of the housing 100 can be set in various ways. Exemplarily, the housing 100 can be in the shape of a water droplet. In another example, the housing 100 can be circular.

[0042] The housing 100 can be integrally formed or assembled. Exemplarily, the housing 100 is assembled from components. Among them, the housing 100 includes an upper cover and a lower shell. The air inlet 120 is provided on the lower shell. The upper cover is covered on the lower shell to jointly enclose an inner cavity 110 with the lower shell. There are various connection methods between the upper cover and the lower shell, which can be snap connection, threaded connection, etc., and are not limited here.

[0043] Refer to Figure 2 And Figure 5 , in an embodiment, the follower fan 200 is rotatably connected to the side of the housing 100 away from the air inlet 120. With this arrangement, the airflow enters the inner cavity 110 from the air inlet 120 and acts on the follower fan 200. The follower fan 200 is subjected to force and also receives a thrust in the air inlet direction when rotating. The thrust causes the follower fan 200 to always have a tendency to move towards the side of the housing 100 away from the air inlet 120, so that the follower fan 200 can maintain its relative position with the housing 100 and be more stable when rotating, which is more conducive to diffusing the airflow.

[0044] There are many ways to set the rotatable connection between the follower fan 200 and the housing 100. Exemplarily, the inner cavity 110 includes a cavity wall away from the air inlet 120. A rotation hole 140 is provided on the cavity wall. The fan 200 includes a main body 210 and a plurality of fan blades 220 arranged around the main body 210. The main body 210 is rotatably connected to the rotation hole 140. With this arrangement, the relative rotation between the follower fan 200 and the housing 100 is realized. Specifically, the cavity wall is provided with a boss, the rotation hole 140 is provided on the boss, and the main body 210 includes a fixed shaft rotatably connected to the rotation hole 140.

[0045] Preferably, the fixed shaft can be made of a metal material. A metal sleeve is sleeved on the boss, and the fixed shaft is adapted to the inner circle of the metal sleeve, that is, the rotation hole 140. With this arrangement, the connection strength between the two can be improved, and the connection part where the two rotate is less likely to be worn, improving the durability of the air guiding device 1000.

[0046] Refer to Figure 3 , Figure 5 And Figure 6 , in an embodiment, the housing 100 is further provided with a second air outlet 150. The second air outlet 150 is disposed opposite to the air inlet 120, and the fan 200 is located between the second air outlet 150 and the air inlet 120. With this arrangement, part of the airflow entering the inner cavity 110 from the air inlet 120 can be blown out through the second air outlet 150, which helps to improve air circulation and the overall ventilation effect.

[0047] It is worth mentioning that by implementing the above embodiments, the air guiding device 1000 has different configuration options, and users can choose whether to be equipped with the second air outlet 150 according to the actual situation and preferences, providing more choices for users to meet their different needs, and the flexibility of the air guiding device 1000 is better.

[0048] Refer to Figures 3 to 7 , in one embodiment, the housing 100 further includes a plurality of partition plates 160, and the plurality of partition plates 160 are arranged around the air inlet 120. Any adjacent partition plates 160 are spaced apart to divide the first air outlet 130 into a plurality of third air outlets 131. Among them, the partition plates 160 extend from the end close to the fan 200 in the rotation direction of the follower fan 200. With such a setting, the plurality of partition plates 160 divide the first air outlet 130 into a plurality of third air outlets 131, and the air volume of each third air outlet 131 can be in a relatively balanced state, enabling the air guiding device 1000 to achieve the effect of uniform air output and improving the user experience; and the partition plates 160 also play a guiding role. After the air flow enters the third air outlet 131, the partition plates 160 can help the air flow flow more smoothly to the outside of the housing 100, increasing the air circulation and cooling the vehicle interior more efficiently.

[0049] Furthermore, the distance between two adjacent partition plates 160 ( Figure 7 shown as H1 and H2 in

[0050] Refer to Figure 8 , in one embodiment, the air guiding device 1000 further includes a clamping seat 300, and the clamping seat 300 is installed on the housing 100, and the clamping seat 300 is used to fix the housing 100. Specifically, the clamping seat 300 is connected to the blades of the vehicle air conditioner outlet to realize the fixation of the air guiding device 1000 to the air conditioner outlet.

[0051] Refer to Figure 9, in a specific embodiment, the housing 100 is sequentially provided with an opening 180 and a receiving groove 170 in the air inlet direction, and the opening 180 communicates with the receiving groove 170; the clamping seat 300 includes a clamping portion 330, a connecting portion 310, and a limiting portion 320. The connecting portion 310 is located between the clamping portion 330 and the limiting portion 320. The connecting portion 310 passes through the opening 180, and the limiting portion 320 is received in the receiving groove 170. The width of the limiting portion 320 in the first direction (such as the Y direction shown in Figure 9 ), (such as H3 shown in Figure 9 ) is greater than the width of the opening 180 (such as H4 shown in Figure 9 ), where the first direction is perpendicular to the air inlet direction. With such a setting, the width of the limiting portion 320 is greater than the width of the opening 180, which can limit the movement of the limiting portion 320 in the direction away from the receiving groove 170, thereby limiting and fixing the limiting portion 320 in the receiving groove 170. The clamping seat 300 is more firmly connected to the housing 100, enhancing the structural stability of the air guiding device 1000.

[0052] Specifically, both the opening 180 and the receiving groove 170 extend in the second direction (such as the Z direction shown in Figure 10 ), and the second direction is perpendicular to the first direction and the air inlet direction. Thus, the limiting portion 320 can move relative to the receiving groove 170 in the second direction to change the relative position between the clamping seat 300 and the housing 100, thereby adjusting the relative position between the air guiding device 1000 and the air conditioner outlet, ensuring that the air guiding device 1000 can stably intake air.

[0053] Preferably, the opening 180 and the receiving groove 170 extend in the second direction and penetrate through the housing 100 to form a notch, so that the connecting portion 310 and the limiting portion 320 can be respectively placed into the opening 180 and the receiving groove 170 through the notch, realizing the quick connection between the clamping seat 300 and the housing 100, and the assembly is more convenient; and the two can also be disassembled and separated, facilitating storage.

[0054] Referring to Figure 10 , in a more specific embodiment, the receiving groove 170 includes groove walls oppositely arranged in the first direction. A plurality of convex bump groups 171 are provided on the groove walls. The plurality of convex bump groups 171 are spaced apart in the second direction. The convex bump group 171 includes two convex bumps 171a, and a positioning groove 171b is formed between the two convex bumps 171a. The limiting portion 320 has an arc surface 321, and the arc surface 321 is engaged with the positioning groove 171b. With such a setting, the arc surface 321 can be engaged with any positioning groove 171b, so that after the clamping seat 300 adjusts its relative position with the housing 100, it can maintain its own non-displacement, and the stability of the air guiding device 1000 is better after the position adjustment. Moreover, after the user adjusts the clamping seat 300, the air inlet direction of the air inlet 120 and the air outlet direction of the air conditioner outlet can be aligned to ensure the air intake volume.

[0055] Refer again Figure 9 The clamping portion 330 includes two spaced clamping arms 331, and the clamping arm 331 includes an elastic section 331a and a clamping section 331b. The clamping section 331b is disposed on the side of the elastic section 331a away from the connecting portion 310. The elastic section 331a is bent by force, so that the two clamping sections 331b can be relatively opened, so that the blade can be clamped between the two clamping sections 331b. During installation, the user only needs to roughly align the blade between the two clamping arms 331, and then apply force to push the blade between the two clamping sections 331b to achieve a fixed connection. The fixing method is simpler and faster.

[0056] In addition, the advantage of such a setting is that when the user turns the button to change the direction of the blade, the clamping seat 300 can also move along with it, thereby always keeping the air inlet 120 of the air guide device 1000 consistent with the air outlet direction of the car air conditioning vent, ensuring that the air guide device 1000 can stably intake air.

[0057] Specifically, the two clamping sections 331 b are provided with anti-skid bosses on the sides facing each other. The anti-skid bosses can increase the contact area with the blades, thereby increasing the friction force and making the connection more stable.

For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
