Description

Technical Field

[0001] The present invention relates to the field of air outlet wind direction regulating devices, and in particular to an regulating mechanism in which a single driver drives two groups of blades and an air outlet regulating device. Background Art

[0002] Currently, in the automotive industry, air-conditioning vents generally use a manual adjustment knob mechanism to adjust the ventilation volume and wind direction. The disadvantage is that it can easily distract the driver's attention, posing a certain safety hazard during driving. In terms of appearance, since many manually operated parts are all exposed, it not only affects the appearance, but also causes protrusions inside the car, which may cause unnecessary injuries to passengers in a collision accident. There are also motor-driven blades to achieve automatic adjustment functions, but their traditional motor control has a relatively complex structure, high manufacturing costs and poor mechanical durability.

[0003] To this end, a Chinese invention patent application (application number: 202110441294.1) in the published state discloses an on-vehicle automatic air sweeping outlet adjustment device and an automobile, comprising: a housing having a first air outlet port and a second air outlet port formed on both sides of its upper end; a front air damper mechanism disposed in the upper half of the housing, the front air damper mechanism being capable of controlling the air outlet direction of the first air outlet port and the second air outlet port; and a rear air damper mechanism disposed in the lower half of the housing, the rear air damper mechanism being capable of controlling the opening and closing of the first air outlet port and the second air outlet port. Compared with the prior art, the advantage of this invention is that it realizes the air sweeping function of the air conditioner by directly driving the completely hidden blades using a stepper motor. This new mechanism improves the aesthetics of the vehicle interior, eliminates the protrusion problem by eliminating the operating components of the conventional air vents, reduces the need for passengers to manually adjust the air conditioner, improves passenger comfort and safety, and improves reliability. However, this air outlet adjustment device uses two motors to adjust the wind direction when controlling the wind direction, which is expensive to manufacture and occupies a large space in the vehicle.

DETAILED DESCRIPTION

[0036] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0037] like Figures 1 to 11 As shown, in this solution, the adjustment mechanism in the air outlet adjustment device is mainly described in detail.

The levers 14 are connected to the first and second cams 5 respectively, and the levers 14 are connected to the first and second cams 5 respectively.

[0039] Based on the above embodiments, the technical problem to be solved by the present application is that the prior art requires two drive motors to adjust the air direction of the air outlet, which results in high manufacturing costs and large space occupied in the vehicle. To this end, the adjustment mechanism of the present application includes a fixed member 1, a driving member 4, a first follower 6, and a second follower 7. The fixed member 1 is hingedly connected to a first set of air sweep blades 2 and a second set of air sweep blades 3. The output end of the driving member 4 is connected to a three-claw rotating shaft 5. The three-claw rotating shaft 5 and the first follower 6 and the second follower 7 are both in abutment with each other, and the first follower 6 and the second follower 7 are respectively in movable abutment with the first set of air sweep blades 2 and the second set of air sweep blades 3. When the driving member 4 drives the three-claw rotating shaft 5 to rotate, it can drive the first follower 6 and the second follower 7 to move on the fixed member 1, thereby driving the first set of air sweep blades 2 and the second set of air sweep blades 3 to switch between a first state (rotating in the same direction) and a second state (rotating in opposite directions). In this way, the manufacturing cost of the air direction adjustment mechanism and the space occupied in the vehicle can be reduced.

[0040] Furthermore, the end of the three-claw rotating shaft 5 away from the driving member 4 has a first driving rod 8, a second driving rod 9 and a third driving rod 10; the first follower 6 is provided with a first traction groove 11 and a second traction groove 12 at intervals, the first driving rod 8 is movably inserted in the first traction groove 11, and the second driving rod 9 is movably inserted in the second traction groove 12; the second follower 7 is provided with a third traction groove 13 and a fourth traction groove 14 at intervals, the first follower 6 is movably inserted in the third traction groove 13, and the third driving rod 10 is movably inserted in the fourth traction groove 14; when the driving member 4 drives the first driving rod 8 to move in the first traction groove 11 and the third traction groove 13, it drives the first wind sweeping blade group 2 and the second wind sweeping blade group 3 to rotate in the same direction; when the driving member 4 drives the second driving rod 9 to move in the second traction groove 12 and drives the third driving rod 10 to move in the fourth traction groove 14 at the same time, it drives the first wind sweeping blade group 2 and the second wind sweeping blade group 3 to rotate in the opposite directions.

[0041] Based on the above embodiments, the technical problem to be solved by the present application is how the three-claw rotating shaft 5 drives the first sweeping blade group 2 and the second sweeping blade group 3 to switch between the first state and the second state. To this end, the three-claw rotating shaft 5 of the present application is provided with a first driving rod 8, a second driving rod 9 and a third driving rod 10 at one end away from the driving member 4, the first follower 6 is provided with a first traction groove 11 and a second traction groove 12 at intervals, the second follower 7 is provided with a third traction groove 13 and a fourth traction groove 14 at intervals, the first driving rod 8 is movably inserted in the first traction groove 11 and the third traction groove 13, the second driving rod 9 is movably inserted in the second traction groove 12, and the third driving rod 10 is movably inserted in the fourth traction groove 14.

As the first position, the first driving rod 8 is inserted into the first traction groove 11 and the third traction groove 13. When the three-claw shaft 5 rotates in the clockwise direction as shown in the figure, since the distance between the position of the rotation center of the three-claw shaft 5 and the first traction groove 11 and the second traction groove 13 is decreasing, the three-claw shaft 5 can simultaneously drive the first follower 6 and the second follower 7 to move toward the right side as shown in the figure. When the first follower 6 and the second follower 7 move, they drive the first sweep blade group 2 and the second sweep blade group 3 to rotate synchronously in the counterclockwise direction as shown in the figure. Figure 3 The second position shown and Figure 4 In the third position shown, when the wind direction adjustment mechanism of the present invention is applied to the air outlet, Figure 2 The status shown can control the wind direction of the air outlet to blow to the right side of the diagram. Figure 3 The state shown can control the wind direction of the air outlet to blow directly above the diagram. Figure 4The state shown can control the wind direction of the air outlet to blow toward the left side of the diagram. During the above process, the rotation directions of the first sweeping blade group 2 and the second sweeping blade group 3 are the same, both of which are the movement modes in the first state.

[0043] like Figure 4 As shown, when the first driving rod 8 is disengaged from the first traction groove 11 and the third traction groove 13 and the second driving rod 9 rotates toward the second traction groove 12, and the third driving rod 10 rotates toward the fourth traction groove 14, the three-claw rotating shaft 5 can drive the first driven member 6 to Figure 4 The right side of the figure moves and drives the first sweeping blade group 2 to rotate in the counterclockwise direction as shown in the figure. At the same time, the three-claw shaft 5 can drive the second follower 7 to move to the left and drive the second sweeping blade 17 to rotate in the clockwise direction as shown in the figure, and finally move to Figure 5 In the fourth position shown, during the above process, the first and second sweep blade assemblies 2 and 3 rotate in opposite directions, both in the second state. Thus, the three-claw shaft 5 can drive the first and second sweep blade assemblies 2 and 3 to switch between the first and second states.

[0044] Furthermore, guide portions 15 are provided at the upper ends of the first, second, third, and fourth traction grooves 11, 12, 13, and 14.
