Description

Technical Field

[0001] This utility model belongs to the field of automotive air conditioning, and specifically relates to an automotive air conditioning unit damper control device. Background Technology

[0002] The car air conditioning unit has multiple air dampers, which direct air into different channels. There are generally four types of air dampers, which are used for front airflow, side airflow, foot airflow, and glass defrosting. The opening and closing of the air dampers is generally controlled by a mode drive disc. The mode drive disc is equipped with an arc-shaped guide groove. The air damper is equipped with a damper shaft. By rotating the drive disc, the guide groove guides the transmission structure to drive the damper shaft to rotate and open and close.

[0003] Existing mode drive panels typically set guide slots on a single side. Concentrating multiple guide slots corresponding to multiple dampers on one side has the following drawbacks: Due to the large number of guide slots and the large variation in their curvature, the number and length of guide slots that can be set on a single side cannot be simultaneously optimized. Fewer guide slots result in fewer controlled dampers, and shorter guide slot lengths make it difficult to design combinations of multiple blowing modes. Utility Model Content

[0004] The purpose of this invention is to provide an automotive air conditioning unit damper control device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A car air conditioning unit damper control device includes a fixed part disposed on the air conditioning unit and a drive disc rotatably disposed between the fixed part and the air conditioning unit. The drive disc has a first guide groove and a second guide groove on its two sides respectively. A first driving member is rotatably disposed on the outer surface of the air conditioning unit, and a second driving member is rotatably disposed on the fixed part. The first driving member has a first guide part corresponding to the first guide groove, and the second driving member has a second guide part corresponding to the second guide groove. When the drive disc rotates, the trajectory change of the first guide groove and the second guide groove drives the corresponding driving member to rotate. The driving member is used to actuate the damper shaft to open and close.

[0007] As a further optimization of this utility model, a mounting base extends from the outer surface of the air conditioning unit, and the fixing part is fixedly connected to the mounting base to form a gap between the fixing part and the air conditioning unit to accommodate the drive disk. This solution connects the fixing part by extending the mounting base from the outside of the air conditioning unit, so that a second driving member can be set on the fixing part to utilize the other side of the drive disk.

[0008] As a further optimization of this utility model, one end of the damper shaft extends through to the outside of the air conditioning unit, and the end is provided with a toggle member that cooperates with the drive member to rotate the damper shaft. This solution provides a toggle member on the damper shaft so that the drive member can drive the damper shaft to rotate when it rotates.

[0009] As a further optimization of this utility model, the actuating component is divided into a first actuating component that cooperates with the first driving component and a second actuating component that cooperates with the second driving component. The first driving component and the first actuating component are both sector gears, and the second driving component is an L-shaped arm. One end of the L-shaped arm is rotatably mounted on the fixed part, and the other end is used to drive the second actuating component. This solution specifically provides a structure for the actuating component and the driving component, wherein the first driving component and the first actuating component are set as sector gears, which can adapt to different transmission ratios by the ratio of the gear radii.

[0010] As a further optimization of this utility model, the rotation shaft of the second driving member is radially provided with a side arm, which is used to connect the second guide part. The second guide part is connected through the side arm and enters the second guide groove through the fixing part.

[0011] As a further optimization of this utility model, the second actuating member extends radially from one of the damper shafts, and a sliding groove is provided on the second actuating member. A protruding rod is provided at the end of the second driving member to cooperate with the sliding groove. This solution specifically sets up a structure in which the second driving member drives the second actuating member.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention provides a guide groove on the side of the drive disc away from the air conditioning unit, a fixed part on the air conditioning unit, and a second drive component on the fixed part. The second drive component is driven to rotate by the guide groove on this side, and the second drive component drives one of the corresponding air dampers to open and close. This arrangement links multiple air conditioning dampers, saves on the amount of electrical components used, and achieves the purpose of saving costs. Rotating the second drive component on the fixed part helps to make the structure compact and does not occupy more space in the vehicle. Attached Figure Description

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1-9 As shown, an automotive air conditioning unit damper control device includes a fixed part 2 disposed on an air conditioning unit 6 and a drive disc 1 rotatably disposed between the fixed part 2 and the air conditioning unit 6. The drive disc 1 has a first guide groove 101 and a second guide groove 102 on its two sides. A first driving member 4 is rotatably disposed on the outer surface of the air conditioning unit 6, and a second driving member 5 is rotatably disposed on the fixed part 2. The first driving member 4 has a first guide part 401 corresponding to the first guide groove 101, and the second driving member 5 has a second guide part 502 corresponding to the second guide groove 102. When the drive disc 1 rotates, the corresponding driving member rotates due to the trajectory change of the first guide groove 101 and the second guide groove 102. The driving member is used to actuate the damper shaft 3 to open and close.

[0027] Specifically, the air dampers of the air conditioning unit 6 include a first air damper 601, a second air damper 602, a third air damper 603, and a fourth air damper 604, each having an air damper shaft 3, and the air damper shafts 3 are parallel to each other. The four air dampers are used for front blowing, side blowing, foot blowing, and glass defrosting, respectively. This embodiment requires four guide grooves, including three first guide grooves 101 and one second guide groove 102.

[0028] In this solution, a guide groove is also provided on the side of the drive disc 1 away from the air conditioning unit 6. A fixing part 2 is provided on the air conditioning unit 6, and a second drive member 5 is provided on the fixing part 2. The second drive member 5 is driven to rotate by the guide groove on this side. The second drive member 5 drives one of the corresponding air dampers to open and close. This arrangement links multiple air conditioning dampers, saves the amount of electrical components used, and achieves the purpose of saving costs. Rotating the second drive member 5 on the fixing part 2 helps to make the structure compact and does not occupy more space in the vehicle.

[0029] An installation base extends from the outer surface of the air conditioning unit 6, and the fixing part 2 is fixedly connected to the installation base to form a gap between it and the air conditioning unit 6 to accommodate the drive disk 1. In this solution, the fixing part 2 is connected by extending the installation base from the outside of the air conditioning unit 6, so that a second drive member 5 can be provided on the fixing part 2 to utilize the other side of the drive disk 1.

[0030] One end of the damper shaft 3 extends through to the outside of the air conditioning unit 6, and this end is provided with a toggle member that cooperates with the drive component to rotate the damper shaft 3. This solution provides a toggle member on the damper shaft 3 so that the drive component can drive the damper shaft 3 to rotate when it rotates.

[0031] Specifically, the actuating element is divided into a first actuating element 301 that cooperates with the first driving element 4 and a second actuating element 302 that cooperates with the second driving element 5. Both the first driving element 4 and the first actuating element 301 are sector gears. The second driving element 5 is an L-shaped arm, with one end of the L-shaped arm rotatably mounted on the fixed part 2, and the other end used to drive the second actuating element 302. This solution specifically provides a structure for the actuating element and driving element, wherein the first driving element 4 and the first actuating element 301 are configured as sector gears, which can adapt to different transmission ratios through the ratio of gear radii. The advantage is that... Figure 7 As shown, the radius of the first driving member 4 is larger than that of the first actuating member 301, so that the first driving member 4 can drive the first actuating member 301 to rotate a sufficient angle to open and close the damper with a very small rotation arc. This makes the arc of the first guide groove 101 relatively smooth, and the trajectory of the first guide groove 101 only needs a small undulation to drive the first guide part 401 to move, which is beneficial for laying out multiple first guide grooves 101.

[0032] Correspondingly, the rotation shaft of the second driving member 5 is radially provided with a side arm 501, which is used to connect the second guide part 502. The second guide part 502 passes through the fixing part 2 and enters the second guide groove 102, such as... Figure 5As shown, the rotation axis of the second drive member 5 is set on the fixed part 2, so that the length of the side arm 501 can be set to be shorter. The advantage is that the arc direction of the second guide groove 102 can also be smooth. Only a small undulation is needed to drive the side arm 501 to rotate to a sufficient angle, that is, to drive the second drive member 5 to rotate to a sufficient angle. A sufficient angle refers to the angle range that can drive the damper to open and close.

[0033] The second actuating member 302 extends radially from one of the damper shafts 3, and a sliding groove is provided on the second actuating member 302. The end of the second driving member 5 is provided with a protruding rod that cooperates with the sliding groove. This scheme specifically sets up the structure in which the second driving member 5 drives the second actuating member 302.

[0034] The specific implementation method is as follows: The four dampers have several combination modes, including single-door opening and combined opening. Specifically, when the drive disk 1 is driven by an external motor to rotate to angle A, the four guide parts are in different positions of the guide groove, so that the four drive components are in a rotating / non-rotating state, and the corresponding dampers are in an open / closed state. When the drive disk 1 rotates to angle B, one or more of the four drive components rotate, and the opening and closing combination of the dampers changes. Since the guide grooves are distributed on both sides of the drive disk 1 and the trajectory of the guide grooves is relatively smooth with little undulation, the length of the guide grooves can be set to be long enough. The guide parts can be set to more adjustment states in the guide grooves. For the four guide parts, more air blowing opening and closing combinations can be formed. For example, the opening and closing combinations of the four dampers can be: open / close / close / close, closed / open / close / close, closed / close / open / close, closed / close / close / open, open / close / open / close, closed / open / open / close, ...

[0035] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
