Description

Technical Field

[0001] The utility model relates to the technical field of automotive air conditioner control mechanisms, and particularly relates to a multi-air door linkage mechanism and a vehicle. Background Art

[0002] Automotive air conditioners usually have multiple modes, such as the face-blowing mode, the foot-blowing mode, and the defrosting mode, etc. To achieve these modes, air vents are usually set at corresponding positions, such as the face-blowing air vent, the foot-blowing air vent, and the defrosting air vent, etc. Among them, by setting air doors at the air vents to open and close the corresponding air vents, the adjustment of the corresponding modes can be completed. In the related art, usually a single motor is used to control the air door of a single air vent, that is, the control of each mode is completed independently. Therefore, more motors and connecting rod structures are required.

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0038] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture.

When the combination of technical solutions results in contradictions or is unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0040] In the prior art, each air outlet of an automotive air conditioner is provided with an independent damper assembly. Correspondingly, each damper assembly is controlled by an independent motor, which reduces the design difficulty and enables independent control of the air outlet. However, since an automotive air conditioner has multiple air outlets, such as a face-blowing air outlet, a foot-blowing air outlet, and a defrosting air outlet, etc., the independent damper assemblies and independent motors, although reducing the design difficulty, also increase the number of damper assemblies, especially the number of motors, resulting in an increase in both the weight and cost of the automotive air conditioner, and not conforming to the current development trend of automotive lightweight and compactness.

[0041] The present utility model proposes a multi-damper linkage mechanism.

[0042] Please refer to Figure 1 、 Figure 8 and Figure 9 , in an embodiment of the present utility model, the multi-damper linkage mechanism includes:

[0043] A driving member 100;

[0044] A disk structure 200, the disk structure 200 is sleeved on the rotating shaft 110 of the driving member 100, and the disk structure 200 is provided with a plurality of track grooves 300 distributed along the extending direction of the rotating shaft 110; and

[0045] Damper assemblies, there are multiple groups of damper assemblies, and they are movably connected to the track grooves 300 in one-to-one correspondence. The damper assemblies can move along the extending direction of the corresponding track grooves 300 to control the opening degree of the corresponding air outlets.

[0046] The technical solution of the present utility model is to provide a disc structure 200 on the rotating shaft 110 of the driving member 100. A plurality of track grooves 300 are distributed in the extending direction of the rotating shaft 110 of the disc structure 200. A group of air damper assemblies are movably connected to one track groove 300. Under the action of the corresponding track groove 300, the air damper on the air damper assembly can be driven to switch between opening and closing the corresponding air outlet. Thus, when the driving member 100 controls the rotation of the rotating shaft 110, the disc structure 200 rotates synchronously with the rotating shaft 110. Correspondingly, the plurality of track grooves 300 make a circular motion around the rotating shaft 110, so that the track grooves 300 act on the corresponding air damper assemblies relatively, thereby driving the air damper assemblies to open and close the corresponding air outlets, realizing that the opening degrees of a plurality of air outlets can be controlled by one driving member 100, thus reducing the number of driving members 100, reducing the weight and cost, and conforming to the development trend of vehicle lightweight and compactness.

[0047] It can be understood that when the plurality of track grooves 300 rotate synchronously, the corresponding air damper assemblies can be driven to move synchronously, that is, the opening and closing degrees of the corresponding air outlets can be controlled synchronously. Similarly, by designing the arrangement modes of different track grooves 300, when the plurality of track grooves 300 rotate synchronously, the asynchronous movement of different air damper assemblies can also be realized, that is, a plurality of air outlets can also be opened and closed asynchronously. Among them, the plurality of track grooves 300 are distributed in the extending direction of the rotating shaft 110. Correspondingly, the plurality of air damper assemblies are also distributed in the axial direction of the rotating shaft 110, which not only avoids the interference between different air damper assemblies, but also facilitates the track grooves 300 to independently control the corresponding air damper assemblies, realizing the independent and flexible control of different air outlets. In addition, in this embodiment, the driving member 100 is configured as a motor, and a speed reducer can be arranged at the output end of the motor to transmit power to the rotating shaft 110. By arranging the speed reducer, not only the transmission ratio between the motor and the rotating shaft 110 is changed, but also the flexibility of the position setting of the motor is improved. In other embodiments, the disc structure 200 can also be directly sleeved in the rotating shaft 110 of the motor, or the driving member 100 is configured as a cylinder or an oil cylinder.

[0048] It should be noted that the air outlet in this embodiment is the air outlet of an automotive air conditioner, including outlets for cold air, hot air, fresh air or humid air. Without loss of generality, the positions of different air outlets of the automotive air conditioner are also different. For example, the front blowing surface air outlet is in the front row, the rear blowing surface air outlet is in the rear row, the defrosting air outlet is close to the windshield, and the foot blowing air outlet is close to the chassis. Thus, different damper components can be in different circumferential orientations relative to the disk structure 200. When the corresponding damper components are controlled to move by the track groove 300, the possibility of interference between different damper components corresponding to different air outlets is relatively low, thereby ensuring the stability of independent control of multiple air outlets. For the disk structure 200, the disk structure 200 can be an independent integral component or a combined component formed by connecting multiple drive disks. In addition, the quantity descriptions such as multiple, multiple groups, multiple segments or multiple roots in this solution include quantities of two, two groups, two segments or two roots and above. Without loss of generality, for the way in which the track groove 300 controls the movement of the corresponding damper component, the damper component can abut against the groove side wall of the track groove 300. During the process of the track groove 300 rotating around the rotating shaft 110, the damper component can not only be pushed by the track groove 300 to control the opening and closing of the corresponding air outlet, but also slide relative to the groove side wall of the track groove 300 to avoid interfering with the rotation of the disk structure.

[0049] In one embodiment, please refer to Figure 8 and Figure 9, the track groove 300 extends in an arc shape and has a driving section 401 and an idle running section 402. In the driving section 401, the air door assembly controls the opening degree of the corresponding air outlet. In the idle running section 402, the air door of the air door assembly remains stable. It can be understood that during the rotation of the disk structure 200, the track groove 300 synchronously makes a circular motion around the rotating shaft 110, that is, the driving section 401 and the idle running section 402 also synchronously make a circular motion around the rotating shaft 110. Among them, the air door assembly has a pushing end that moves along the extending direction of the track groove 300. When the driving section 401 rotates to the point where its groove side wall abuts against the pushing end of the air door assembly, the air door assembly is affected by the acting force of the driving section 401, and then controls the corresponding air door to move to open or close the corresponding air outlet. When the idle running section 402 rotates to the same circumferential position as the pushing end of the air door assembly, there is no pushing action between the pushing end of the air door assembly and the groove side wall of the track groove 300, that is, the track groove 300 does not pull the air door assembly to move, and the air door remains stable and does not adjust the opening degree of the corresponding air outlet. In this way, by adjusting the positional relationship between the driving section 401 and the idle running section 402, when multiple track grooves 300 rotate synchronously, the active states of different track grooves 300 driving different air door assemblies can be the same or different, realizing the independent movement of multiple air door assemblies without interference with each other, and improving the flexibility of controlling multiple air outlets. It should be noted that the circumferential two ends of different track grooves 300 around the rotating shaft 110 are in the same radial direction of the rotating shaft 110, so as to avoid a situation where after a certain track groove 300 rotates to the end, another track groove 300 still has the movement space for the pushing end of the corresponding air door assembly, resulting in mutual interference between different track grooves 300 when driving the corresponding air door assemblies.

[0050] Further, please refer to Figure 8 and Figure 9 , the driving section 401 and the idle running section 402 are continuously arranged and are respectively arranged at both ends of the corresponding track groove 300. It can be understood that as an embodiment of the driving section 401 and the idle running section 402, the driving section 401 and the idle running section 402 are respectively arranged at both ends in the extending direction of the track groove 300. In this way, during the rotation of the track groove 300, after one of the driving section 401 and the idle running section 402 completes the action on the air door assembly, the other immediately controls the air door assembly to realize the continuous control of the opening and closing of the air door. Among them, the driving section 401 and the idle running section 402 of different track grooves 300 can be arranged in reverse to avoid the situation where different air outlets are opened and closed simultaneously. Of course, the driving section 401 and the idle running section 402 of different track grooves 300 can also be arranged at the same end to realize the simultaneous opening and closing of different air outlets.

[0051] Similarly, in another embodiment, please refer to Figure 8 and Figure 9, the driving section 401 and / or the idling section 402 of a track groove 300 includes multiple segments, and the driving section 401 and the idling section 402 of a track groove 300 are arranged according to a preset pattern. It can be understood that for the same track groove 300, multiple driving sections 401 can be set, or multiple idling sections 402 can be set, or multiple driving sections 401 and multiple idling sections 402 can be set. The arrangement of multiple driving sections 401 or multiple idling sections 402 can be flexibly set according to the pattern requirements. For example, if the preset pattern requires opening and closing the face air outlet first and then the foot air outlet, during the rotation of the rotating shaft 110, first, the driving section 401 of the track groove 300 that controls the face air door drives the face air door assembly to open and close the face air outlet. Here, the idling section 402 of the track groove 300 that controls the foot air door 530 moves relative to the pushing end of the foot air assembly; then, the driving section 401 of the track groove 300 that controls the foot air door 530 drives the foot air door assembly to open and close the foot air outlet. Here, the idling section 402 of the track groove 300 that controls the face air door moves relative to the pushing end of the face air door assembly, which is manifested as: in a circumference of the rotating shaft 110, the driving section 401 and the idling section 402 of the track groove 300 that controls the face air door are distributed in sequence, while the idling section 402 and the driving section 401 of the track groove that controls the foot air door 530 are distributed in sequence; or, if the preset pattern requires opening or closing the face air outlet and the foot air outlet in sequence, taking a certain circumference direction of the rotating shaft 110 as the upstream and downstream direction of the track groove 300, the driving section 401 of the track groove 300 that controls opening the face air outlet is adjacent to the downstream of the driving section 401 of the track groove 300 that controls opening the foot air outlet, and then, the driving section 401 of the track groove 300 that controls closing the foot air outlet is adjacent to the downstream of the driving section 401 of the track groove 300 that controls closing the face air outlet. Similarly, the idling section 402 of the track groove 300 that controls the face air door and the idling section 402 of the track groove 300 that controls the foot air door 530 are distributed with reference to the above driving section 401. Thus, on the axial projection of the rotating shaft 110, the idling section 402 of the track groove 300 that controls the foot air door 530 coincides with the driving section 401 of the track groove 300 that controls the face air door, and the driving section 401 of the track groove 300 that controls the foot air door 530 coincides with the idling section 402 of the track groove 300 that controls the face air door. Of course, the above description takes the face air outlet and the foot air outlet as examples to analyze and explain the preset pattern, and the control of other air outlets can be similarly referred to. The actual situation of the preset pattern is configured according to the parameters and models of the vehicle, and no further examples are given here.

[0052] In one embodiment, please refer to Figure 8 and Figure 9, the driving segments 401 of one track groove 300 and the driving segments 401 of other track grooves 300 are spaced or staggered in the circumferential direction of the rotating shaft 110. It should be noted that when the driving segments 401 of different track grooves 300 have an overlapping part in the circumferential direction of the rotating shaft 110, that is, the driving segments 401 of the different track grooves 300 have a part corresponding to the same arc of the rotating shaft 110, so that the air outlets controlled by the different track grooves 300 can be opened and closed synchronously. According to the degree of circumferential staggering, it can be completely synchronous opening and closing, or one track groove 300 can first control the corresponding air outlet to open or close. Before it is completely opened or closed, another track groove 300 can then immediately open or close the corresponding air outlet, realizing the situation where different air outlets have partial synchronous opening and closing. When the driving segments 401 of different track grooves 300 are spaced in the circumferential direction of the rotating shaft 110, that is, the driving segments 401 of the different track grooves 300 do not have a part corresponding to the same arc of the rotating shaft 110, so that the air outlets controlled by different track grooves 300 are opened and closed asynchronously. That is, after one track groove 300 controls the corresponding air outlet to open and close, another track groove 300 can control the corresponding air outlet to open and close. It appears that in the axial direction of the rotating shaft 110, the driving segment 401 of one of the different track grooves 300 is opposite to the idle running segment 402 of the other.

[0053] In one embodiment, please refer to Figure 8 and Figure 9 , the idle running segment 402 extends in an arc shape in the circumferential direction of the rotating shaft 110, and the driving segment 401 extends eccentrically relative to the circumferential direction of the rotating shaft 110. It can be understood that the driving segment 401 drives the corresponding damper assembly to move through the trajectory formed by its extending direction, and then controls the opening and closing of the corresponding air outlet. From this, it can be seen that setting the driving segment 401 to extend eccentrically relative to the circumferential direction of the rotating shaft 110, that is, setting it in a non-circular arc shape. During the rotation of the track groove 300, the driving segment 401 needs to change its relative position relationship with the damper assembly, so as to push the damper assembly to move, and then control the opening degree of the corresponding air outlet. When the damper assembly moves to the idle running segment 402, the damper assembly does not contact the track groove 300 in the idle running segment 402. From this, it can be seen that during the rotation of the disk structure 200, the relative distance between the idle running segment 402 and the damper assembly needs to be kept stable. In this way, the idle running segment 402 is set to extend in an arc shape around the circumferential direction of the rotating shaft 110. During the rotation of the track groove 300, the idle running segment 402 can maintain the distance from the damper assembly, thus avoiding interfering with the state of the damper assembly, that is, the corresponding damper can maintain stability. Among them, the arc-shaped extension of the driving segment 401 is determined according to the preset mode, the force required by the corresponding damper, the relative position relationship between the track groove 300 and the air outlet, and the relationship between the rotation direction of the disk structure 200, and will not be elaborated here one by one.

[0054] In one embodiment, please refer to Figure 3 、Figure 5 and Figure 7 The disc structure 200 includes a plurality of transmission discs that are arranged in parallel on the rotating shaft 110, and a track groove 300 is provided on at least one side of the transmission disc. It can be understood that the end of a damper assembly close to the disc structure 200 is arranged on one side of a transmission disc, so that different damper assemblies are also distributed in the axial direction of the rotating shaft 110 and are located on opposite sides of the transmission disc, so that the multiple damper assemblies are staggered in the axial direction of the rotating shaft 110, ensuring that different track grooves 300 can stably and independently control the corresponding damper assemblies, while also avoiding mutual interference between different damper assemblies, ensuring independent and flexible control of different air outlets. Specifically, in this embodiment, the disc structure 200 includes a first transmission disc 201 and a second transmission disc 202, a track groove 300 is provided on one side of the first transmission disc 201, and track grooves 300 are provided on both sides of the second transmission disc 202; or, in another embodiment, three or more transmission discs are provided according to the number of damper assemblies. Of course, in other embodiments, the disc structure 200 can also be configured as an integrated structure, having multiple disc parts distributed in the extension direction of the rotating shaft 110, one track groove 300 is set in one disc part, and multiple track grooves 300 are on the same side of multiple disc parts, thereby avoiding mutual interference between different damper components.

[0055] In one implementation, please refer to Figure 1 A damper assembly includes a lever and multiple connecting rods connected in sequence. The damper is mounted on the lever, which is rotatably mounted on the vehicle frame. The damper is driven to open and close the corresponding air outlet by toggling the lever. The end of the connecting rod away from the lever is movably connected to a track groove 300. When the corresponding transmission plate rotates, the track groove 300 rotates about the rotation axis 110, driving the connecting rod to move radially, thereby transmitting the driving force toward the lever along the multiple connecting rods. The connecting rod away from the transmission plate then toggles the corresponding lever, completing the opening and closing of the air outlet. The multiple connecting rods are rotationally connected to each other, maintaining a stable relative position between the lever and the transmission plate. Through the rotational connection of the multiple connecting rods, when the track groove 300 makes circular motion, the track groove 300 can change the radial position of the connecting rod relative to the rotation axis 110, causing two adjacent connecting rods to rotate relative to each other, thereby toggling the lever, thereby driving the damper to open and close the corresponding air outlet. It should be noted that the position of the lever will be different for different damper assemblies. For a damper assembly, the positional relationship between the lever and the corresponding transmission plate affects the posture and shape of multiple connecting rods. During the rotation of the transmission plate, the direction of the force between the track groove 300 and the connecting rod is consistent with the relative position of the adjacent connecting rods. At this time, some connecting rods are set to have a turning portion, which can change the direction of force transmission, avoid the situation where the forces of the connected connecting rods conflict with each other and affect the transmission of the driving force, and ensure the flexibility and stability of the damper assembly in controlling the opening and closing of the air outlet.

[0056] For example, in one embodiment, please refer to Figure 4 、 Figure 5 and Figure 9 , a damper assembly is configured as a foot-blowing damper assembly 500, a track groove 300 is configured as a first track groove 301, the foot-blowing damper assembly 500 includes a foot-blowing lever 520 and multiple foot-blowing connecting rods 510 connected in sequence, one end of the foot-blowing connecting rod 510 away from the foot-blowing lever 520 is movably connected to the first track groove 301, and the foot-blowing lever 520 is provided with a foot-blowing damper 530. In this embodiment, the transmission disk of the first track groove 301 is set as the second transmission disk 202, and the first track groove 301 is arranged on the side of the second transmission disk 202 away from the first transmission disk 201. In this way, when the driving member 100 controls the second transmission disk 202 to rotate, the first track groove 301 rotates synchronously, thereby driving the corresponding foot-blowing connecting rod 510 to move along the radial direction of the second transmission disk 202. Under the transmission action of multiple foot-blowing connecting rods 510, the transmission reversal of the force is realized, and then the foot-blowing connecting rod 510 away from the second transmission disk 202 is used to move the foot-blowing lever 520, thereby driving the foot-blowing damper 530 to open and close the foot-blowing air outlet, completing the control of the air conditioner's air outlet toward the feet, and avoiding interference between the foot-blowing connecting rod 510 and other connecting rods, thereby ensuring the independence and flexibility of controlling the foot-blowing air outlet.

[0057] Similarly, in one embodiment, please refer to Figure 6 、 Figure 7 and Figure 8 A damper assembly is configured as a defrost damper assembly 600, and a track groove 300 is configured as a second track groove 302. The defrost damper assembly 600 includes a defrost lever 620 and a plurality of defrost connecting rods 610 connected in sequence. One end of the defrost connecting rod 610, which is away from the defrost lever 620, is movably connected to the second track groove 302. The defrost lever 620 is provided with a defrost damper 630. In this embodiment, the transmission disc provided with the second track groove 302 is the first transmission disc 201. The second track groove 302 is configured on the side of the first transmission disc 201 facing the second transmission disc 202 and away from the motor body. It can be understood that the first transmission disc 201 and the second transmission disc 202 are sequentially sleeved on the rotating shaft 110 in a direction away from the motor body. In this way, when the driving member 100 controls the rotation of the first transmission disk 201, the second track groove 302 rotates synchronously, thereby driving the corresponding defrost link 610 to move radially along the first transmission disk 201. Under the transmission action of multiple defrost links 610, the transmission reversal of the force is realized, and then the defrost lever 620 is moved by the defrost link 610 away from the first transmission disk 201, thereby driving the defrost damper 630 to open and close the defrost air outlet, completing the control of the windshield defrost, and avoiding the defrost link 610 from interfering with the connecting rods of other damper components, thereby ensuring the flexibility and independence of controlling the defrost air outlet.

[0058] In one embodiment, please refer toFigure 2 、 Figure 3 and Figure 9 A damper assembly is configured as a blowing-face damper assembly 700, and one track groove 300 is configured as a third track groove 303. The blowing-face damper assembly 700 includes a front blowing-face lever 720 and a plurality of front blowing-face connecting rods 710 connected in sequence. One end of the front blowing-face connecting rod 710, which is remote from the front blowing-face lever 720, is movably connected to the third track groove 303. The front blowing-face lever 720 is provided with a front blowing-face damper 730. In this embodiment, the transmission disc provided with the third track groove 303 is the second transmission disc 202. The third track groove 303 is configured on the side of the second transmission disc 202 that faces the first transmission disc 201, which is also the side facing the motor body. In this way, when the driving member 100 controls the second transmission disk 202 to rotate, the third track groove 303 rotates synchronously, thereby driving the corresponding front blowing surface connecting rod 710 to move radially along the second transmission disk 202. Under the transmission action of multiple front blowing surface connecting rods 710, the transmission reversal of the force is realized, and then the front blowing surface lever 720 is moved by the front blowing surface connecting rod 710 away from the second transmission disk 202, thereby driving the front blowing surface damper 730 to open and close the front blowing surface air outlet, completing the control of the air conditioner's air outlet toward the front row of people's faces, and avoiding the front blowing surface connecting rod 710 from interfering with the connecting rods of other damper components, thereby ensuring the flexibility and independence of controlling the front blowing surface air outlet.

[0059] Further, in this embodiment, please continue to refer to Figure 2 and Figure 3The blowing surface damper assembly 700 also includes a rear blowing surface lever 760 and multiple rear blowing surface connecting rods 750 connected in sequence. One end of the front blowing surface lever 720 is provided with a transmission guide groove 740, and one end of the rear blowing surface connecting rod 750 away from the rear blowing surface lever 760 is movably connected to the transmission guide groove 740. The rear blowing surface lever 760 is provided with a rear blowing surface damper 770. Without loss of generality, the transmission guide groove 740 extends in an arc shape around the circumference of the front-facing lever 720. As the second transmission disc 202 pulls the front-facing damper 730 to open and close the front-row air vents, the transmission guide groove 740 is synchronously driven along with the front-facing lever 720, causing the rear-facing connecting rod 750 to move radially along the front-facing lever 720. Driven by the multiple rear-facing connecting rods 750, the force is reversed. The rear-facing connecting rod 750, which is located farther away from the front-facing lever 720, then drives the rear-facing damper 770 to open and close the rear-facing air vents, thereby controlling the air flow directed toward the faces of the rear passengers. This synchronized control of the front and rear-facing airflow simplifies the complexity of the transmission structure within the disc structure 200, facilitating design. Furthermore, the synchronized control of the airflow to the front and rear rows ensures a pleasant riding experience for both front and rear passengers. Of course, in other embodiments, a transmission disk for controlling the rear blowing surface connecting rod 750 can also be set on the rotating shaft 110, and a track groove 300 for controlling the rear blowing surface air door 770 can be set accordingly to realize separate control of the rear blowing surface air outlet, that is, the front blowing surface air door 730 and the rear blowing surface air door 770 are connected in parallel to the two track grooves 300 on the disk structure 200.

[0060] In one embodiment, please refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 7 The multi-damper linkage mechanism further includes a mounting member 800, with the rotating shaft 110 extending toward the mounting member 800. The mounting member 800 is provided with a mounting position, and the transmission disc is rotatably disposed in the mounting position. The mounting member 800 is mounted on the vehicle frame, and the driving member 100 can be connected to the mounting member 800 or to the vehicle frame. In this way, the mounting member 800 and the driving member 100 remain stable relative to each other and the vehicle frame. The transmission disc is mounted on the mounting member 800, and the mounting position forms a limiting support for the transmission disc, ensuring that the transmission disc can rotate stably under the action of the driving member 100, thereby preventing deviation of the damper assembly during the transmission process, thereby improving the reliability and accuracy of the air conditioner air outlet opening control.
