[0024] In conventional technologies, the air outlet direction is adjusted manually.

When the toggle key is no longer adjusted, the grid group is fixed in that direction, ensuring constant airflow. However, the air outlet only has a single air outlet mode, which means that the air can only be blown in one fixed direction, making it difficult to meet the diverse needs of users.

[0025] To solve the above problems, the embodiments of the present application provide an air outlet device and a vehicle that can not only achieve fixed air outlet direction by adjusting the grille, but also avoid air outlet direction concentration in a certain direction, thereby achieving the effect of simulating natural wind. Note that in this embodiment, natural wind is considered to be simulated unless air outlet is fixed in one direction.

Fig. 2 is a diagram showing the configuration of the blowing device in Fig. 1 after the outer panel of the blowing port has been removed. Fig. 3 is a diagram showing the configuration of the blowing device in Fig. 1 after the outer panel of the blowing port and the inner panel of the blowing port have been removed. Fig. 4 is a partial schematic diagram 1 of the blowing device in Fig. 1. Fig. 5 is a partial schematic diagram 2 of the blowing device in Fig. 1.

[0028] 1 and 2, an embodiment of the present application provides a blowing device including an air outlet case 10, a grill assembly 20, and a rotating assembly 30. The blowing device is a part of a vehicle, which further includes an air conditioner main body, and the blowing device is removably attached to the air conditioner main body.

[0029] The air outlet case 10 has an air outlet 101, the grill assembly 20 is provided in the air outlet 101, and the rotating assembly 30 is provided in the air outlet case 10.

[0030] 3 to 5, the grill assembly 20 includes a plurality of grills 21 and a plurality of direction adjusting members 22 for adjusting the air guide direction of the grills 21. Each grill 21 is fixedly connected to one direction adjusting member 22.

[0031] The rotating assembly 30 comprises a plurality of rotating bodies 31 and a drive mechanism for rotating or stopping the plurality of rotating bodies 31, each of which includes a first groove portion and a second groove portion that are interconnected in the circumferential direction of the rotating body 31, one end of the directional adjustment member 22 being slidably provided in the first groove portion and / or the second groove portion, and the first groove portion and the second groove portion being used to adjust the position of the directional adjustment member 22 in the rotational direction of the grill 21.

[0032] The plurality of direction adjusting members 22 are used to make the air guide direction of all the grills 21 of the grill assembly the same when the plurality of rotating bodies 31 are stopped and the plurality of direction adjusting members 22 are positioned in the first groove portions of the corresponding rotating bodies 31.

[0033] The plurality of direction adjusting members 22 are used to make the air guide directions of at least two grilles 21 different when the plurality of rotating bodies 31 are stopped and the plurality of direction adjusting members 22 are respectively positioned in the second groove portions of the corresponding rotating bodies 31, and / or The plurality of direction adjusting members 22 are used to change the airflow direction of all grills 21 of the grill assembly when the plurality of rotating bodies 31 rotate and the plurality of direction adjusting members 22 are positioned in the first groove portion and / or the second groove portion of the corresponding rotating body 31.

[0034] Here, the grills 21 are rotatably provided on the air outlet case 10, and the rotation axes of all the grills 21 of the grill assembly 20 extend in the same direction. In some examples, the grills 21 can rotate left and right in the vehicle.

[0035] The directional adjustment member 22 is fixedly connected to the grille 21, and the position of the directional adjustment member 22 can be changed only in the circumferential direction of the grille 21.

[0036] The number of the grills 21 can be set according to actual needs. The number of the direction adjusting members 22 is provided corresponding to the number of the grills 21.

[0037] The drive mechanism is fixed to the air outlet case 10 and can control the plurality of rotating bodies 31 to rotate simultaneously, and can also control the plurality of rotating bodies 31 to stop simultaneously.

[0038] The rotating body 31 may be a cylindrical member having an axis, and the rotating body 31 rotates along this axis, and the first groove portion and the second groove portion can be connected in the circumferential direction of the rotating body 31 to form a closed figure.

[0039] In the circumferential direction of the rotating body 31, the rotation of the rotating body 31 causes the direction adjustment member 22 to slide relative to the rotating body 31. Specifically, the direction adjustment member 22 may slide relative to the rotating body 31 in the first groove portion, in the second groove portion, or in both the first groove portion and the second groove portion.

[0040] The number of the rotating bodies 31 can be set according to actual needs. At least one direction adjusting member 22 is provided on the rotating body 31.

[0041] The rotating body 31 rotates in the circumferential direction of the rotating body 31, and the first groove portion and the second groove portion can adjust the position of the direction adjustment member 22 in the rotation direction of the grill 21, i.e., the position of the direction adjustment member 22 in the rotation direction of the grill 21 changes, and the direction adjustment member 22 rotates the grill 21.

[0042] The direction adjusting members 22 make all of the grilles 21 of the grill assembly 20 guide air in the same direction when the rotating bodies 31 are stopped and each of the direction adjusting members 22 is positioned in the first groove portion of the corresponding rotating body 31. Specifically, after the driving mechanism controls the rotating bodies 31 to stop simultaneously, the direction adjusting members 22 are positioned in the first groove portion of the corresponding rotating body 31, and the positions of the direction adjusting members 22 in the rotation direction of the corresponding grilles 21 are the same. This makes it possible to make the rotation angles of all of the grilles 21 of the grill assembly 20 the same, thereby making the air guide directions of all of the grilles 21 of the grill assembly 20 the same and achieving directional airflow. The rotation angle of the grill 21 is the angle of the grill 21 with respect to the longitudinal direction of the vehicle.

[0043] The direction adjusting members 22 are used to differentiate the airflow directions of at least two grilles 21 when the rotors 31 are stopped and each of the direction adjusting members 22 is positioned in the second groove of the corresponding rotor 31. Specifically, after the drive mechanism controls the rotors 31 to stop simultaneously, the direction adjusting members 22 are positioned in the second groove of the corresponding rotor 31. The positions of the direction adjusting members 22 in the rotation direction of the corresponding grill 21 are different for at least two of the direction adjusting members 22. By differentiating the rotation angles of the at least two grilles 21, the airflow directions of at least two of all grilles 21 in the grill assembly 20 can be differentiated. This also prevents the airflow direction from concentrating in a certain direction, achieving the effect of simulating natural wind. In this embodiment, unless the airflow is fixed in one direction, it is considered to be simulated natural wind.

[0044] The plurality of direction adjusting members 22 are used to change the airflow direction of all grills 21 of the grill assembly 20 when the plurality of rotating bodies 31 rotate and the plurality of direction adjusting members 22 are positioned in the first groove portion and / or the second groove portion of the corresponding rotating body 31. Specifically, when the forward and reverse rotations of the multiple rotating bodies 31 are controlled by the drive mechanism, the multiple direction adjustment members 22 are positioned in the first groove portions of the corresponding rotating bodies 31, and the position of each direction adjustment member 22 in the rotation direction of the corresponding grill 21 is adjusted, thereby changing the air guide direction of all grills 21 of the grill assembly 20; when the forward and reverse rotations of the multiple rotating bodies 31 are controlled by the drive mechanism, the multiple direction adjustment members 22 are positioned in the second groove portions of the corresponding rotating bodies 31, and the position of each direction adjustment member 22 in the rotation direction of the corresponding grill 21 is adjusted, thereby changing the air guide direction of all grills 21 of the grill assembly 20; when the forward and reverse rotations of the multiple rotating bodies 31 are controlled by the drive mechanism, the multiple direction adjustment members 22 are positioned in the first and second groove portions of the corresponding rotating bodies 31, and the position of each direction adjustment member 22 in the rotation direction of the corresponding grill 21 is adjusted, thereby changing the air guide direction of all grills 21 of the grill assembly 20. By installing them in this manner, it is possible to avoid the airflow direction from concentrating in a certain direction, and to achieve the effect of simulating natural wind. Note that the plurality of direction adjusting members 22 are respectively positioned in the first groove portion and the second groove portion of the corresponding rotor 31. That is, the direction adjusting members 22 may be positioned in either the first groove portion or the second groove portion of the rotor 31.

[0045] The blowing device according to the embodiment of the present application uses a plurality of direction adjusting members 22 to make the airflow direction of all grills 21 of the grill assembly the same when the plurality of rotating bodies 31 are stopped and the plurality of direction adjusting members 22 are positioned in the first grooves of the corresponding rotating bodies 31, and uses a plurality of direction adjusting members 22 to make the airflow direction of at least two grills 21 different when the plurality of rotating bodies 31 are stopped and the plurality of direction adjusting members 22 are positioned in the second grooves of the corresponding rotating bodies 31. This not only achieves directional blowing, but also prevents the blowing direction from concentrating in a certain direction, achieving the effect of simulating natural wind, realizing a variety of blowing modes for the air outlet, and meeting the diverse needs of users.

[0046] The blowing device according to the embodiment of the present application can use a plurality of direction adjusting members 22 to make the airflow direction of all the grills 21 of the grill assembly the same when the plurality of rotating bodies 31 are stopped and the plurality of direction adjusting members 22 are respectively positioned in the first groove portions of the corresponding rotating bodies 31, and can use a plurality of direction adjusting members 22 to change the airflow direction of all the grills 21 of the grill assembly when the plurality of rotating bodies 31 are rotating and the plurality of direction adjusting members 22 are respectively positioned in the first groove portions and / or second groove portions of the corresponding rotating bodies 31, thereby not only realizing directional blowing, but also preventing the blowing direction from concentrating in a certain direction, achieving the effect of simulating natural wind, thereby realizing a variety of blowing modes for the air outlet and meeting the diverse needs of users.

The direction adjusting members 22 change the airflow direction of all the grills 21 of the grill assembly when the rotating bodies 31 are rotating and the direction adjusting members 22 are located in the first grooves and / or second grooves of the corresponding rotating bodies 31, thereby not only realizing directional air outlet but also preventing the air outlet from concentrating in a certain direction, achieving the effect of simulating natural wind, realizing diversification of the air outlet air outlet air outlet modes, and meeting the diverse needs of users.

[0049] Here, a plurality of grills 21 are provided in the first outlet 1011, and a plurality of grills 21 are provided in the second outlet 1012.

[0050] The number of grills 21 in the first outlet 1011 may be the same as or different from the number of grills in the second outlet 1012. In this embodiment, the number of grills 21 in the first outlet 1011 is the same as the number of grills in the second outlet 1012.

In the extending direction of the unfolded plane, the length of the first region A is equal to the length of the third region C, the length of the second region B is equal to the length of the fourth region D, the first groove 3111 is located in the first region A, the second groove 3121 is located in the second region B, the third groove 3112 is located in the third region C, and the fourth groove 3122 is located in the fourth region D. The first groove 3111, the second groove 3121, the third groove 3112, and the fourth groove 3122 are connected in sequence on the unfolded plane of the circumferential surface of the rotating body 31. The first groove 3111 overlaps with the third groove 3112 after translating 180 degrees along the extension direction of the unfolded plane of the circumferential surface of the rotating body 31, and the second groove 3121 completely misaligns with the fourth groove 3122 after translating 180 degrees along the extension direction of the unfolded plane of the circumferential surface of the rotating body 31, i.e., does not overlap with either position.

[0066] Furthermore, when the forward and reverse rotation of multiple rotating bodies 31 is controlled by the driving mechanism, the swing position and swing angle of all grills 21 of the grill assembly 20 can be changed by changing the rotation angle range of the rotating bodies 31.Therefore, by controlling the position of all direction adjustment members 22 of the grill assembly 20 relative to their corresponding rotating bodies 31, it is possible to control the swing position and swing angle of all grills 21 of the grill assembly 20, and it is possible to realize blowing modes with different swing positions, blowing modes with different swing angles, and blowing modes with different swing positions and swing angles. The rotation angle section of the rotating body 31 may be one of the first groove 3111, the second groove 3121, the third groove 3112 and the fourth groove 3122, or may be two connected grooves of the first groove 3111, the second groove 3121, the third groove 3112 and the fourth groove 3122, and all the direction adjustment members 22 of the grill assembly 20 may be simultaneously positioned in three sequentially connected grooves of the first groove 3111, the second groove 3121, the third groove 3112 and the fourth groove 3122, or all the direction adjustment members 22 of the grill assembly 20 may be simultaneously positioned in the first groove 3111, the second groove 3121, the third groove 3112 and the fourth groove 3122.

[0067] Furthermore, when the drive mechanism controls the forward and reverse rotation of multiple rotating bodies 31, blowing modes with different swing angular velocities, swing positions, and swing angles can be realized by controlling the rotation speed of the drive motor 32 and controlling the positions of all direction adjustment members 22 of the grill assembly 20 relative to their corresponding rotating bodies 31.

[0068] Furthermore, the two direction adjustment members 22 in each rotating body 31 correspond to one grill 21 in the first outlet 1011 and one grill 21 in the second outlet 1012, respectively, and the two direction adjustment members 22 in each rotating body 31 are arranged at 180 degree intervals in the circumferential direction of the rotating body 31.

[0069] In one alternative embodiment, five grills 21 are provided in the first outlet 1011, and five grills 21 are provided in the second outlet 1012, and the rotating assembly 30 includes five rotating bodies 31. The development planes on the circumferential surfaces of the five rotating bodies 31 may all be the first development plane, and the five rotating bodies 31 include a first rotating body, a second rotating body, a third rotating body, a fourth rotating body, and a fifth rotating body, and the first groove 3111 of the first rotating body, the first groove 3111 of the second rotating body, the first groove 3111 of the third rotating body, the first groove 3111 of the fourth rotating body, and the first groove 3111 of the fifth rotating body overlap on the first development plane, and the third groove 3112 of the first rotating body, the third groove 3112 of the second rotating body, the third groove 3112 of the third rotating body, and the third groove 3112 of the fourth rotating body overlap on the first development plane. The third groove 3112 and the third groove 3112 of the fifth rotating body overlap in the first developed plane, the second groove 3121 of the first rotating body, the second groove 3121 of the second rotating body, the second groove 3121 of the third rotating body, the second groove 3121 of the fourth rotating body and the second groove 3121 of the fifth rotating body are completely offset in the first developed plane, and the fourth groove 3122 of the first rotating body, the fourth groove 3122 of the second rotating body, the fourth groove 3122 of the third rotating body, the fourth groove 3122 of the fourth rotating body and the fourth groove 3122 of the fifth rotating body are completely offset in the first developed plane.

[0070] After the rotating body 31 of the rotating assembly 30 stops, all of the grills 21 in the first outlet 1011 are positioned in the first groove 3111, and all of the grills 21 in the second outlet 1012 are positioned in the third groove 3112, so that the rotation angles of all of the grills 21 in the grill assembly 20 can be made the same, and the air guide directions of all of the grills 21 in the grill assembly 20 can be made the same, thereby realizing directional blowing.

[0071] After the rotating body 31 of the rotating assembly 30 stops, all of the grills 21 in the first outlet 1011 are positioned in the second groove 3121, and all of the grills 21 in the second outlet 1012 are positioned in the fourth groove 3122, so that the rotation angles of all of the grills 21 in the grill assembly 20 can be made different, and the air guide directions of all of the grills 21 in the grill assembly 20 can be made different, thereby avoiding the blowing direction from concentrating in a certain direction and achieving the effect of simulating natural wind.

[0072] As one possible embodiment, as shown in Figures 2 and 4, the direction adjustment member 22 includes a direction adjustment ball 221 and a direction adjustment lever 222, one end of the direction adjustment lever 222 is fixedly connected to the grill 21, the other end of the direction adjustment lever 222 is fixedly connected to the direction adjustment ball 221, and the direction adjustment ball 221 is fitted into the first groove portion and the second groove portion.

[0073] The first groove portion and the second groove portion need to be designed so that the direction adjusting ball 221 is not easily caught when the rotating body 31 rotates.

[0074] The direction adjustment member 22 further includes a flap 223 fixed to the direction adjustment lever 222, and the air outlet inner plate 12 has a through hole, the direction adjustment lever 222 passes through the through hole, and the flap 223 is arranged to cover the through hole, thereby avoiding the problem of air leakage through the through hole of the air outlet inner plate 12.

[0075] An embodiment of the present application provides a vehicle, which includes an air conditioner main body and a blowing device, the blowing device being detachably attached to the air conditioner main body.
