Description

Technical Field

[0001] The utility model relates to the technical field of automobile air conditioners, in particular to an automobile air conditioner damper actuator which can be adjusted at will. Background Art

[0002] The automobile air conditioning system is a device that realizes cooling, heating, ventilation and air purification in the car. It can provide a comfortable riding environment for passengers, reduce driver fatigue and improve driving safety. Therefore, the air conditioning device has become an important indicator of whether the car has complete functions.

[0003] Although most of the damper actuators equipped in most car air conditioning systems are equipped with automatic air sweeping function, if you want to adjust the air outlet fan blades to a specified angle, you can only do it by manually adjusting the fan blades or sliding the pulley on one side without power. This adjustment method is difficult to achieve precise adjustment in unclear lighting conditions. If driving on highways, it will affect the driver's attention and increase the danger of driving. At the same time, it is necessary to add an additional transmission mechanism for manual adjustment, which increases the cost and usage volume.

In daily use, by adopting the above technical solution, when the circuit board receives a signal from the automobile ECU, the motor is started, the transmission gear set is operated, and the power is transmitted to the execution power shaft through the transmission part. The execution power shaft drives the damper shaft to rotate. When the damper is fully opened or fully closed, the transmission gear set is disengaged from the transmission part, and the disconnection part corresponds to it, so that the execution power shaft cannot continue to rotate. However, the actuator cannot adjust the air outlet fan blades to a specified angle at will. Summary of the invention

In this embodiment, the driving gear set includes a meshing double pinion 4-1 and a double large gear 4-2, one of the double pinion 4-1 and the double large gear 4-2 cooperates with the motor worm at the output end of the motor 3, and the other meshes with the output gear 4-3. The steering member 7 cooperates with the output gear 4-3.

[0031] Embodiment 2 differs from Embodiment 1 in that a protrusion and a groove that can be embedded in or disengaged from each other are provided between the mating surfaces of the steering member 7 and the output gear 4 - 3 .

[0032] Furthermore, if Figure 4 As shown, the steering member 7 includes a column coaxially inserted into the output gear 4-3 and a truncated cone 7-2 coaxially arranged outside the column. Figure 3As shown, the middle part of the output gear 4-3 is provided with an axial blind hole 4-3-1 for inserting one end of the column, and the other end of the column passes through the housing and is connected to the air conditioner fan blade. The side of the truncated cone 7-2 matches the end face of the output gear 4-3, and the side of the truncated cone 7-2 and the end face of the output gear 4-3 are provided with the protrusions and grooves that can be embedded or disengaged. That is, the side of the truncated cone 7-2 is provided with a protrusion, and the end face of the output gear 4-3 is provided with a groove 4-3-2.

[0033] Embodiment 3 is different from Embodiment 2 in that the protrusion includes a plurality of limit bevel blocks 7-2-1 arranged at equal angles on the side of the truncated cone 7-2. In this embodiment, three limit bevel blocks 7-2-1 are provided. The cross section of the limit bevel block 7-2-1 perpendicular to the radial direction of the truncated cone 7-2 is a trapezoidal structure, the bottom edge of the trapezoidal structure is in contact with the truncated cone 7-2, the top edge faces the end face of the output gear 4-3, and the waists on both sides of the trapezoidal structure are beveled edges, so that the limit bevel block 7-2-1 can be separated from the groove 4-3-2 under the action of external force.

[0034] Embodiment 4 is different from Embodiment 2 in that the protrusions include a plurality of limiting protrusions arranged at equal angles on the side of the cone 7-2, and the surface of the limiting protrusions is an arc surface.

[0035] Embodiment 5 is different from Embodiment 3 in that the elastic member is provided between the side of the truncated table 7-2 away from the output gear 4-3 and the housing, and the elastic member is an abutment spring 6 sleeved on the column.

[0036] The cylinder includes a cylinder 7-1 inserted into the blind hole 4-3-1 of the output gear 4-3 and a guide column 7-3 passing through the abutment spring 6 and the housing. The cylinder 7-1 is coaxially arranged with the guide column 7-3, and the diameter of the cylinder 7-1 is larger than the diameter of the guide column 7-3. In addition, in this embodiment, the cylinder 7-1 is a hollow cylinder.

The upper cover 1 is provided with a hole 1-2 for the end of the column away from the output gear 4-3, namely the guide column 7-3 to pass through.

[0038] Furthermore, if Figure 2 As shown, the inner side of the upper cover 1 is provided with a boss 1-1 which presses against the abutment spring 6. When no power is supplied, the bottom of the abutment spring 6 fits tightly against the boss 1-1, and the top of the abutment spring 6 fits tightly against the cone 7-2 of the steering member 7. The abutment spring 6 is in a compressed state at this time.

[0039] The working principle of this utility model:

[0040] When the air outlet of the damper actuator operates normally, the contact spring 6 set between the upper cover 1 and the steering member 7 is in a compressed state, which will press the steering member 7 against the bottom surface of the output gear 4-3, and the limit bevel 7-2-1 is embedded in the groove 4-3-2. At this time, the limit bevel 7-2-1 and the groove 4-3-2 remain relatively still due to the friction force, and the steering member 7 and the output gear 4-3 become a whole. The steering member 7 will also drive the air conditioner outlet fan blade to swing; when the air conditioner outlet fan blade is blocked by external force, the external force it receives will also be transmitted to the steering member 7 connected to it, so the steering member 7 will also stop moving. When the external force received is larger than the friction between the two, the limit bevel 7-2-1 will slide out of the groove 4-3-2, and the transmission mechanism 4 will continue to move under the drive of the motor, and the steering member 7 will remain still, and the air conditioner outlet fan blade connected to the steering member 7 will also remain still, so as to achieve the purpose of conveniently stopping the fan blade at the desired air outlet angle.
