Description

Technical Field

[0001] This utility model relates to the field of automotive air vent technology, specifically to a double-layer airflow adjustment mechanism for automotive air conditioning vents. Background Technology

[0002] Dual-layer air vents are a new air vent structure in modern automobiles. The upper and lower air vents have different orientations so that the air is delivered to different heights in the cabin, thereby making the temperature of the entire cabin more even.

[0003] Each of the upper and lower air outlets requires a set of blades to adjust the air direction. In this case, existing technologies often require two independent power mechanisms to control the two sets of blades in the upper and lower air outlets respectively, resulting in a high cost and a large space occupied by the entire air direction adjustment mechanism. Utility Model Content

The synchronous transmission assembly is slidably disposed at the air outlet; the power assembly is connected to one of the upper blade group and the lower blade group; when the power assembly drives one of the upper blade group and the lower blade group to move, the other is synchronously driven by the sliding movement of the synchronous transmission assembly at the air outlet.

[0006] In practical use, this utility model, through the setting of two sets of blades, upper and lower, meets the basic requirements for air direction adjustment of the upper and lower air outlets. By setting a synchronous transmission component connected to the upper and lower blade sets and a power component connected to one of the upper and lower blade sets in the air outlet structure, it can be realized that when a single power component drives one blade set to move, the other blade set is driven by the synchronous transmission component to move synchronously.

[0009] This utility model discloses a double-layer wind direction adjustment mechanism, wherein the upper blade group includes multiple first sub-blades and a first gear disposed on one of the first sub-blades; the first gear engages with the first rack; the lower blade group includes multiple second sub-blades and a second gear disposed on one of the second sub-blades; the second gear engages with the second rack. When one of the first rack and the second rack is driven by one of the first gear and the second gear, the sliding part slides in the air outlet.

[0010] This utility model discloses a double-layer wind direction adjustment mechanism, wherein the power component includes a power unit and a transmission rod extending from the power unit; the transmission rod is connected to one of the first sub-blades or one of the second sub-blades.

Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.

[0018] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] Please see Figure 1-4The double-layer wind direction adjustment mechanism shown includes an upper blade group 1, a lower blade group 2, a synchronous transmission component 3 disposed between the upper blade group 1 and the lower blade group 2, and a power component 4 disposed between the upper blade group 1 and the lower blade group 2. The synchronous transmission component 3 is slidably disposed at the air outlet; the power component 4 is connected to one of the upper blade group 1 and the lower blade group 2; when the power component 4 drives one of the upper blade group 1 and the lower blade group 2 to move, the other is synchronously driven by the sliding movement of the synchronous transmission component 3 at the air outlet.

[0020] In practical use, this utility model, through the setting of two sets of blades, upper blade group 1 and lower blade group 2, meets the basic requirements for air direction adjustment of the upper and lower air outlets. By setting a synchronous transmission component 3 connected to the upper blade group 1 and lower blade group 2, and a power component 4 connected to one of the upper blade group 1 and lower blade group 2 in the air outlet structure, it can be realized that when a single power component 4 drives one blade group to move, the other blade group is driven by the synchronous transmission component 3 to move synchronously. Compared with setting two power components 4 independently for the upper and lower air outlets, the cost is lower and the space occupied is smaller.

[0021] Please continue reading. Figure 1-4 The synchronous transmission component 3 includes a main body 31, a sliding part 32 disposed on the lower end face of the main body 31, a first rack 33 disposed on one side of the main body 31, and a second rack 34 disposed on the other side of the main body 31; the sliding part 32 cooperates with the air outlet so that the synchronous transmission component 3 can slide in the air outlet.

[0022] Specifically, the main body 31 is the base of the entire synchronous transmission assembly 3, which is used to support other substructures of the synchronous transmission assembly 3. The sliding part 32 is set as the lower end face of the main body 31, which is used to cooperate with the air outlet structure to realize the synchronous transmission assembly 3 sliding along the set direction of the air outlet structure. The first rack 33 and the second rack 34 on both sides of the main body 31 are used to cooperate with the upper blade group 1 and the lower blade group 2 to transmit force.

[0023] Furthermore, in this embodiment, the sliding part 32 is configured as a slider protruding downward from the lower end of the main body part 31. Correspondingly, the air outlet structure is provided with a groove that cooperates with the slider so as to realize the sliding of the synchronous transmission component 3.

[0024] Please continue reading. Figure 1-4The synchronous transmission assembly 3 further includes a first compensation part 35 disposed on one side of the main body 31 and a second compensation part 36 disposed on the other side of the main body 31; the first rack 33 is connected to the main body 31 via the first compensation part 35; and the second rack 34 is connected to the main body 31 via the second compensation part 36.

[0025] It is understandable that, due to the different internal structures of automobiles, the distance from the main body 31 to the upper and lower air outlets may differ. When the synchronous transmission assembly 3 further includes the first compensation part 35 and the second compensation part 36, the first rack 33 and the second rack 34 can extend to the appropriate positions of the upper and lower air outlets and form a tight fit with the upper blade group 1 and the lower blade group 2.

[0026] Furthermore, in this embodiment, the sliding part 32 can be provided in two places, one located on the lower end face of the aforementioned main body 31, and the other located on one side of the first compensation part 35. The other sliding part 32 also cooperates with the air outlet structure. Under the combined action of the two sliding parts 32, the sliding action of the entire synchronous transmission assembly 3 in the air outlet structure is more stable.

[0027] Please continue reading. Figure 1-4 The upper blade group 1 includes multiple first sub-blades 11 and a first gear 12 disposed on one of the first sub-blades 11; the first gear 12 engages with the first rack 33; the lower blade group 2 includes multiple second sub-blades 21 and a second gear 22 disposed on one of the second sub-blades 21; the second gear 22 engages with the second rack 34; when one of the first rack 33 and the second rack 34 is driven by one of the first gear 12 and the second gear 22, the sliding part 32 slides in the air outlet.

[0028] Specifically, the upper blade group 1 controls the airflow direction of the upper air outlet by oscillating multiple first sub-blades 11, and transfers power through the cooperation of the first gear 12 and the first rack 33; the lower blade group 2 controls the airflow direction of the lower air outlet by oscillating multiple second sub-blades 21, and transfers power through the cooperation of the second gear 22 and the second rack 34, so that when a single power component 4 drives one blade group to move, the other blade group is driven by the synchronous transmission component 3 to move synchronously.

[0029] Please continue reading. Figure 1-4 The power assembly 4 includes a power unit 41 and a transmission rod 42 extending from the power unit 41; the transmission rod 42 is connected to one of the first sub-blades 11 or one of the second sub-blades 21.

[0030] Specifically, the power unit 41 is fixed in the air outlet structure, and the transmission rod 42 extends out from the automatic force unit 41 and is connected to one of the first sub-blades 11 or one of the second sub-blades 21, so that the rotational action provided by the power unit 41 can be converted into the swinging action of the first sub-blade 11 or the second sub-blade 21, thereby controlling the two sets of blades in the two-layer air outlet.

[0031] Please continue reading. Figure 1-4 The transmission rod 42 is connected to one of the first sub-blades 11 so that the first sub-blade 11 is rotated under the control of the transmission rod 42; the upper blade group 1 includes an upper connecting rod 13, and multiple first sub-blades 11 are disposed on the upper connecting rod 13; the first gear 12 is connected to another first sub-blade 11 so that when the first sub-blade 11 rotates, it drives the synchronous transmission assembly 3 to slide via the first rack 33.

[0032] Specifically, in some embodiments, the upper blade assembly 1 receives power from the power unit 41 and drives the synchronous transmission assembly 3 to slide, thus bearing a large torque in different directions. When the transmission rod 42 and the first gear 12 are respectively set on two different first sub-blades 11, the same first sub-blade 11 is prevented from bearing excessive torque in different directions, reducing damage to the first sub-blade 11. Multiple first sub-blades 11 move synchronously through the upper connecting rod 13, thereby playing the role of power transmission and driving the synchronous transmission assembly 3 to slide.

[0033] Please continue reading. Figure 1-4 The lower blade assembly 2 includes a lower connecting rod 23, and multiple second sub-blades 21 are disposed on the lower connecting rod 23; when the second rack 34 drives one of the second sub-blades 21 to swing via the second gear 22, the other second sub-blades 21 swing synchronously via the lower connecting rod 23.

[0034] It is understandable that when the synchronous transmission assembly 3 slides, the second rack 34 drives the second gear 22 to rotate, which in turn drives one of the second sub-blades 21 connected to the second gear 22 to swing. Then, the second sub-blade 21 drives the entire set of second sub-blades 21 to swing through the lower connecting rod 23.

[0035] Based on the above, the present invention provides an automotive air conditioning vent, including the aforementioned dual-layer airflow adjustment mechanism, comprising a housing; the dual-layer airflow adjustment mechanism is disposed in the housing to realize airflow adjustment of the upper and lower air vents.

[0036] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
