[0026] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] Please refer to Figures 1-5 A windless drum structure as shown, which includes a drum carrier 1, a windless drum 2, and a drive assembly 3; wherein the drum carrier 1 includes a drum bearing portion 11; wherein the windless drum 2 includes a drum body 21 rotatably arranged on the drum bearing portion 11 and a rotating shaft 22 arranged inside the drum body 21; the rotating shaft 22 includes a rotating shaft body 221 and at least one row of connecting rod assemblies 222 arranged along the length direction of the rotating shaft body 221; the connecting rod assemblies 222 are used to connect the rotating shaft body 221 and the inner wall of the drum body 21; wherein the drive assembly 3 includes a drive main tooth portion 31 arranged on the drum carrier 1 and a drive sub-tooth portion 32 arranged at one end of the rotating shaft 22; the drive main tooth portion 31 drives the drive sub-tooth portion 32, and then drives the drum body 21 to rotate through the rotating shaft 22.

[0028] During actual use, the present invention is provided with a drum carrier 1 for installing and protecting the windless drum 2. The windless drum 2 includes a drum body 21 and a rotating shaft 22, and the rotating shaft 22 includes a rotating shaft body 221 and a connecting rod assembly 222. The connecting rod assembly 222 supports the drum body 21 from the inside, improving the structural strength of the drum body 21 and reducing the damage and cracking that are prone to occur when affected by hot and cold air for a long time; the drive assembly 3 includes a drive main tooth portion 31 and a drive sub-tooth portion 32. The drive main tooth portion 31 is arranged on the drum carrier 1, and the drive sub-tooth portion 32 is arranged at one end of the rotating shaft 22, thus avoiding the direct connection of the drum body 21 to an external power source and reducing the damage and cracking of the drum body 21 caused by directly bearing the torque brought by the external power source, and improving the service life of the drum body 21.

[0029] Please continue to refer to Figure 1 、 Figure 2 , wherein the drum bearing portion 11 includes an arc-shaped support plate 111 and mounting portions 112 arranged at both ends of the arc-shaped support plate 111; the drum body 21 is arranged to be rotatably connected between the two mounting portions 112; through this structural design with balanced ends, both ends of the drum body 21 can be protected, and the rotation action of the drum body 21 driven by the drive assembly 3 can be more balanced in force, thus reducing cracking caused by uneven local stress.

[0030] A windless feeling drum structure of the present utility model, wherein the inner wall of the arc-shaped support plate 111 is set to cooperate with the outer wall of the drum body 21, so that the drum body 21 is supported by the arc-shaped support plate 111 when rotating.

[0031] When the drum body 21 is driven by the driving component 3 to rotate, the inner wall of the arc-shaped support plate 111 can support the drum body 21, thereby dispersing the stress of the drum body 21, so that the drum body 21 is not easily cracked during long-term use.

[0032] Please continue to refer to Figure 1 、 Figure 2 、 Figure 4 , wherein, the drum carrier 1 further includes an air inlet duct 12; the air inlet duct 12 is arranged to communicate with the drum body 21.

[0033] Specifically, the air inlet duct 12 is connected to the air supply system of the vehicle, air enters from the air inlet duct 12, passes through the drum bearing part 11 and then enters the drum body 21, and finally blows out windless feeling wind through the action of the drum body 21.

[0034] Please continue to refer to Figure 4 、 Figure 5 , wherein, the drum body 21 includes a windless feeling air outlet surface 211 and two wind shielding surfaces 212 arranged on both sides of the windless feeling air outlet surface 211; the drum body 21 has a notch 213, and the notch 213 is arranged between the two wind shielding surfaces 212.

[0035] During use, the drum body 21 can be rotated to select to open or close. When the air inlet duct 12 is opposite to the notch 213, air enters from the notch 213 and blows out from the windless feeling air outlet surface 211, thereby blowing out windless feeling wind; when any one of the wind shielding surfaces 212 is opposite to the notch 213, the drum body 21 is in a closed state.

[0036] Furthermore, the windless feeling air outlet surface 211 has a plurality of air outlet holes 2111; and the area of the air outlet holes 2111 gradually decreases from the central axis of the windless feeling air outlet surface 211 along both ends; through the arrangement of the plurality of air outlet holes 2111, the air can be divided into multiple sub-airflows when passing through the windless feeling air outlet surface 211, and since the area of the air outlet holes 2111 gradually decreases from the central axis of the windless feeling air outlet surface 211 along both ends, there will be a difference in the pressure between the sub-airflows, and these sub-airflows with different pressures disturb each other, so that the blown wind has less disturbing feeling to the user.

[0037] Please continue to refer to Figure 4 、 Figure 5, wherein the connecting rod assembly 222 is arranged in at least two rows and circumferentially distributed along the rotating shaft body 221; the connecting rod assemblies 222 are respectively arranged on two wind shielding surfaces 212.

[0038] Specifically, the connecting rod assembly 222 includes a plurality of connecting rods evenly distributed along the length direction of the rotating shaft body 221. Since these connecting rods are evenly distributed on the inner wall of the drum body 21, when the rotating shaft body 221 rotates, the torque is evenly distributed on the inner wall of the drum body 21 instead of being concentrated on a certain part, so that the drum body 21 is not easily cracked or damaged; and the connecting rods are arranged at intervals, and the hindering effect on the wind is relatively small.

[0039] It is worth mentioning that, as Figure 4 shown in the embodiment, according to the overall structure and strength requirements of the automotive air outlet assembly, the connecting rod assembly 222 is arranged in three groups, with one group of connecting rod assemblies 222 provided on the upper wind shielding surface 212 and two groups of connecting rod assemblies 222 provided on the lower wind shielding surface 212.

[0040] Please continue to refer to Figure 1 , Figure 3 , wherein the driving main tooth part 31 includes a turntable 311 rotatably arranged on the drum carrier 1, a power source connecting part 312 arranged on one side of the turntable 311, and a driving tooth 313 arranged on the other side of the turntable 311; the driving sub-tooth part 32 is arranged to mesh with the driving tooth 313.

[0041] Specifically, the power source connecting part 312 is used to connect an external power source, such as an externally connected actuator. When the external power source works, the turntable 311 can be driven to rotate through the power source connecting part 312, and then the driving sub-tooth part 32 can be driven to rotate through the driving tooth 313, and finally the drum body 21 can be driven to rotate through the rotating shaft 22, thus avoiding cracking and damage caused by excessive torque when the actuator directly drives the drum body 21.

[0042] An automotive air outlet includes the windless drum structure as described above.

[0043] The above is only an illustration of the best embodiment of the present invention, but it should not be construed as a limitation to the claims. The present invention is not limited to the above embodiments, and its specific structure allows changes. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
