[0037] With the update and iteration of vehicle products, consumers' demand for interior products in vehicle cabins is also upgrading, and the requirements for the aesthetics and functionality of interior products are gradually increasing. Taking the air outlet of the heat exchange equipment in the vehicle cabin as an example, most of the interiors of vehicle products on the market are rectangular grille air outlets, which occupy a large amount of space on the vehicle dashboard. At the same time, the shape is traditional and the decorativeness needs to be improved.

[0038] In response to this, some vehicles have designed hidden air outlets or round air outlets on the dashboard to replace rectangular grille air outlets to improve the appearance. Among them, round air outlets are popular because of their aesthetics, low processing difficulty and small size.

[0039] However, circular air outlets have the defect of small air outlet range due to their shape. Due to the limitation of the cross-sectional area of ​​the air outlet, circular air outlets usually do not have the function of sweeping air, and the air diffusion effect is weak. The direct air outlet form affects the user experience of the driver and passengers. In addition, circular air outlets are mostly surface treated by mature processes such as electroplating, spark pattern, and spray-free. This decorative layer is difficult to replace during the service life of the vehicle, and the visual difference between different products is small, and the aesthetics are limited.

[0040] In order to solve the problems of the prior art, the embodiment of the present application provides an air nozzle for an air outlet of a heat exchange device of a vehicle, an air outlet of a heat exchange device, and a vehicle. The air nozzle provided in the embodiment of the present application is first introduced below.

[0041] See also Figures 1 to 3In the first aspect, the embodiment of the present application provides an air nozzle for the air outlet of a vehicle heat exchange device, the air nozzle comprising a decorative member 100 and a first stopper 200, the first stopper 200 being detachably connected to the air outlet of the vehicle heat exchange device, and the decorative member 100 being driven to rotate around the first stopper 200 and the air outlet of the vehicle heat exchange device. The decorative member 100 comprises a coaxially arranged decorative inner ring 110, a decorative outer ring 120, and at least three passive blades 130 connected between the decorative inner ring 110 and the decorative outer ring 120, the at least three passive blades 130 being arranged at intervals along the outer peripheral wall of the decorative inner ring 110; the first stopper 200 is provided with a first guide structure, at least one of the decorative inner ring 110, the decorative outer ring 120, and the passive blades 130 being connected to the first guide structure.

[0042] The decorative member 100 has a plurality of hollow areas, which are formed by the decorative inner ring 110, the decorative outer ring 120 and two adjacent passive blades 130. When the vehicle heat exchange device is started, the airflow flows through the hollow areas to the vehicle cabin, and the airflow hits the surface of the passive blades 130, driving the passive blades 130 to move along the tangential direction. Each passive blade 130 is driven to move along the tangential direction, driving the decorative member 100 to move as a whole. Limited by the first guide structure, at least part of the decorative member 100 moves along the first guide structure, so that the decorative member 100 rotates relative to the first limiter 200 and the air outlet assembly of the vehicle.

[0043] Thus, the driver and passengers can know the opening and closing status of the vehicle heat exchange device by observing the rotation of the decorative part 100. When air flows out of the air outlet of the heat exchange device and the decorative part 100 rotates, the passive blades 130 disturb the flow field at the air outlet of the heat exchange device, weaken the direct blowing phenomenon existing in the circular air outlet, accelerate the diffusion of the air flow at the air outlet of the heat exchange device, and diffuse the directional wind emitted from the air outlet of the vehicle heat exchange device into a soft wind with more uniform flow.

[0044] It can be understood that the air nozzle as a whole can be detachably installed on the air outlet of the vehicle's heat exchange equipment through the first limiter 200. The decorative part 100 can be made of different materials or processed using different techniques to change the visual effect of the air nozzle. The air outlet of the vehicle's heat exchange equipment can achieve visual changes by replacing the air nozzle to meet the personalized needs of the car owner.

[0045] See also Figure 1 In the embodiment provided in the present application, the first stopper 200 is disposed on the outer circumference of the decorative element 100 to limit the rotation axis of the decorative element 100. It can be understood that in other embodiments, the first stopper 200 is disposed on the inner circumference of the decorative element 100 to limit the rotation axis of the decorative element 100, and the present application does not limit this.

[0046] According to certain embodiments of the present application, the passive blades are arranged in an annular array along the outer peripheral wall of the decorative inner ring.

[0047] Exemplarily, the decorative element includes three passive blades, and an interval of 120° is set between two adjacent passive blades.

[0048] Exemplarily, the decorative element includes five passive blades, and an interval of 72° is set between two adjacent passive blades.

[0049] Therefore, the stability and continuity of the rotation of the decorative element along the first guide structure are improved.

[0050] According to some embodiments of the present application, in the first plane where the decorative element 100 is located, the passive blade 130 forms a first angle α with the radial direction of the decorative element 100 , where 0°<α<90°.

[0051] Optionally, the first angle α is not greater than 45°.

[0052] Optionally, the first angle α is not greater than 30°.

[0053] Thus, the passive blades 130 are tilted relative to the radial direction of the decorative element 100 to increase the contact area between the passive blades 130 and the airflow, increase the thrust of the airflow on the passive blades 130, and make the decorative element 100 easier to be driven to rotate.

[0054] According to some embodiments of the present application, in a second plane perpendicular to the decorative element 100 , the passive blade 130 is arranged at a second angle β to the normal direction of the decorative element 100 , where 0°<β<90°.

[0055] Optionally, the second angle β is not less than 30°.

[0056] Optionally, the second angle β is not less than 45°.

[0057] Optionally, the second angle β is not greater than 75°.

[0058] Therefore, by changing the size of the second angle β, the thrust component of the airflow on the passive blade 130 in the tangential direction is adjusted, thereby adjusting the driving effect of the airflow at the air outlet of the heat exchange device on the decorative component 100.

[0059] In addition, the contact surface between the passive blade 130 and the airflow can have various forms, and the present application does not impose specific restrictions on this. Exemplarily, the contact surface between the passive blade 130 and the airflow is a planar structure, or the contact surface between the passive blade 130 and the airflow is a curved surface structure, or the contact surface between the passive blade 130 and the airflow is a combination of a planar structure and a curved surface structure, so that the airflow can provide a thrust for the passive blade 130 to move in a tangential direction through the contact surface.

[0060] According to some embodiments of the present application, the first stopper 200 includes at least two first assembling pieces 210, which are sequentially connected end to end and enclosed to form a ring structure to connect the decorative element 100. Two adjacent first assembling pieces 210 are detachably installed.

[0061] Optionally, two adjacent first assembling pieces 210 are snap-connected to facilitate quick assembly and disassembly.

[0062] Optionally, the central angle of each first assembling piece 210 is not greater than 180°, so as to facilitate the assembly of the first assembling piece 210 to the decorative element 100 .

[0063] Optionally, the first limiting member 200 includes two first assembling members 210 , and the central angles of the two first assembling members 210 are both 180°.

[0064] Optionally, the first limiting member 200 includes three first assembling members 210 , and the central angles of the three first assembling members 210 are 100°, 120°, and 140°, respectively.

[0065] Therefore, the assembly between the first limiting member 200 and the decorative member 100 is facilitated, so that the air nozzle can be replaced with the decorative member 100 made of different materials or different processes to improve the aesthetics.

[0066] See also Figure 3 In some embodiments, the first assembly piece 210 is provided with a stop structure 213, which extends along the thickness direction of the first assembly piece 210 and is arranged on the outside of the decorative outer ring 120 to separate the decorative outer ring 120 from other components in the vehicle cabin and the instrument panel to improve the rotational stability of the decorative piece 100.

[0067] Optionally, the stop structures 213 are arranged at intervals along the circumference of the first limiting member 200 .

[0068] Optionally, the stopping structure 213 is configured as a ring-shaped structure.

[0069] See also Figure 3 According to certain embodiments of the present application, the first guide structure includes a first groove 211 and a first protrusion 212. The first groove 211 is opened on the inner wall of the first splicing piece 210 along the circumference of the first limiting piece 200, and the first protrusion 212 is protruded from the inner wall of the first groove 211.

[0070] Optionally, the first protrusions 212 are symmetrically arranged with respect to the thickness direction of the decorative element 100 .

[0071] Optionally, a plurality of first protrusions 212 are arranged along the circumference of the first groove 211 , and the plurality of first protrusions 212 are arranged in a ring array with respect to the decorative element 100 to improve the stability of the decorative element 100 rotating in the first groove 211 .

[0072] Therefore, when the decorative piece 100 rotates relative to the first limit piece 200, the decorative piece 100 and the first protrusion 212 are in sliding contact, reducing the contact area between the decorative piece 100 and the first limit piece 200, thereby reducing the friction force encountered by the decorative piece 100 during the rotation process and improving the smoothness of the rotation of the decorative piece 100.

[0073] See also Figure 1 According to some embodiments of the present application, the nozzle further includes a second stopper 300, the second stopper 300 is provided with a second guide structure, and the second guide structure is coaxially arranged with the first guide structure. The decorative element 100 is sandwiched between the first guide structure and the second guide structure.

[0074] Optionally, the decorative member 100 is connected to the first limiting member 200 and the second limiting member 300 through the passive blade 130 . The passive blade 130 has a connecting portion 131 . The connecting portion 131 is sandwiched between the first guide structure and the second guide structure.

[0075] Thus, the first stopper 200 and the second stopper 300 are respectively arranged on the outer circumference and inner circumference of the decorative member 100, further limiting the rotation axis of the decorative member 100 and improving the stability of the air nozzle. In addition, the second stopper 300 arranged on the inner circumference of the decorative member 100 can separate the decorative member 100 from other components of the air outlet of the heat exchange device to prevent the decorative member 100 from being unexpectedly stuck.

[0076] According to some embodiments of the present application, the second limiting member 300 includes at least two second assembling pieces 310 , and the at least two second assembling pieces 310 are sequentially connected end to end and enclosed to form a ring structure, and two adjacent second assembling pieces 310 are detachably connected.

[0077] Optionally, two adjacent second assembling pieces 310 are snap-connected to facilitate quick assembly and disassembly.

[0078] Optionally, the central angle of each second splicing element 310 is not greater than 180°.

[0079] Optionally, the second limiting member 300 includes two second assembling members 310 , and the central angles of the two second assembling members 310 are both 180°.

[0080] Optionally, the second limiting member 300 includes four second assembling members 310 , and the central angles of the four second assembling members 310 are 30°, 45°, 135°, and 150°, respectively.

[0081] Therefore, it is easy to assemble the second limiting member 300 to the decorative member 100 to separate the decorative member 100 from other components of the air outlet of the heat exchange device.

[0082] According to some embodiments of the present application, the second guiding structure includes a second groove 311 and a second protrusion 312 , and the second groove 311 is opened on the outer peripheral wall of the second assembling piece 310 along the circumferential direction of the second limiting piece 300 .

[0083] Optionally, the second protrusions 312 are symmetrically arranged with respect to the thickness direction of the connecting portion 131 .

[0084] Optionally, a plurality of second protrusions 312 are arranged along the circumference of the second groove 311 , and the plurality of second protrusions 312 are arranged in a ring array with respect to the decorative element 100 to improve the stability of the decorative element 100 rotating in the second groove 311 .

[0085] Therefore, when the decorative piece 100 rotates relative to the second limiting piece 300, the connecting portion 131 and the second protrusion 312 are in sliding contact, reducing the contact area between the connecting portion 131 and the first limiting piece 200, thereby reducing the friction force encountered by the decorative piece 100 during the rotation process and improving the smoothness of the rotation of the decorative piece 100.

[0086] See also Figure 4 In the second aspect, an embodiment of the present application provides an air outlet of a heat exchange device for a vehicle, the air outlet of the heat exchange device comprising a mounting structure and an air nozzle provided in any one of the aforementioned embodiments, wherein two ends of the mounting structure are respectively connected to the vehicle heat exchange device and the vehicle cabin, the mounting structure has an outlet end open toward the vehicle cabin, and the air nozzle is detachably mounted on the outlet end of the mounting structure through a first limit member 200.

[0087] It can be understood that the air outlet of the heat exchange device has all the beneficial effects of the air nozzle of any embodiment of the first aspect mentioned above.

[0088] According to certain embodiments of the present application, a plurality of positioning blocks are circumferentially arranged at the outlet end of the mounting structure, and the first limiting member 200 is provided with a plurality of buckles 220 , the number of the buckles 220 is equal to that of the positioning blocks and they are arranged one-to-one, and the buckles 220 are snap-connected with the positioning blocks.

[0089] Optionally, to facilitate the disassembly and assembly of the air nozzle, a positioning block is arranged on the outer peripheral wall of the outlet end of the mounting structure.

[0090] Therefore, it is convenient to quickly disassemble and assemble the air nozzle to the outlet end of the mounting structure, so as to change the air outlet effect or visual effect of the air outlet of the heat exchange device.
