[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0039] The following will refer to Figures 1-8 The present invention will be described in detail with reference to the embodiments.

[0040] like Figures 1-8 As shown, the central air outlet structure 1000 according to an embodiment of the present invention includes a housing 1, rear blades 2, front blades 3, and a second motor 5. There are multiple housings 1, which are arranged side by side, and each housing 1 defines a through-hole. There are multiple sets of rear blades 2, which are vertically arranged in the multiple air ducts respectively. There is one set of front blades 3, which is located in front of the multiple sets of rear blades 2 and is arranged horizontally at the front end of the multiple air ducts. There is one second motor 5, which is arranged between any two adjacent housings 1 and fixed on one of the two housings 1. The second motor 5 is used to drive the front blades 3 to swing up and down.

[0041] Specifically, there are multiple housings 1 arranged side by side, and each housing 1 is defined with a front-to-back through air duct. During use, the central air outlet structure 1000 of this embodiment of the invention will allow airflow to flow into the multiple air ducts of the multiple housings 1, pass through the rear blades 2 in the multiple housings 1 and the front blades 3 at the front end of the multiple housings 1 in sequence, and then be discharged from the front end of the multiple air ducts.

[0042] There are multiple sets of rear blades 2, each set vertically positioned in a corresponding air duct opening; there is one set of front blades 3, located in front of the multiple sets of rear blades 2 and horizontally positioned at the front end of the multiple air duct openings. Both the front blades 3 and the rear blades 2 serve to guide airflow. The rear blades 2 are used to achieve left-right oscillation and change the air outlet angle of the central air outlet structure 1000 in the left-right direction, while the front blades 3 are used to achieve up-down oscillation and change the air outlet angle of the central air outlet structure 1000 in the up-down direction.

[0043] There is one set of front blades 3, which are horizontally arranged at the front end of multiple air duct openings. That is, there are multiple front blades 3, arranged parallel to each other vertically at the front end of the air duct openings. Each front blade 3 spans the front end of multiple air duct openings and is rotatably supported on the housing 1. In this invention, only one set of front blades 3 is provided, which facilitates the use of a second motor 5 to drive the rotation of all front blades 3.

[0044] There is one second motor 5, which is located between any two adjacent housings 1 and fixed to one of the housings 1. It is used to drive the front blades 3 to swing up and down. First, this invention only requires one second motor 5 to drive the front blades 3 to swing, which meets the usage requirements. Compared with the central air outlet in the prior art that requires two motors to drive the front blades 3 to rotate, the central air outlet structure 1000 of this invention has a lower cost. Second, this invention places the second motor 5 between any two adjacent housings 1. In this way, the installation space occupied by the second motor 5 is the space between the two adjacent housings 1. The second motor 5 does not need to occupy additional space in the left and right directions, which helps to reduce the overall volume of the central air outlet structure 1000 of this invention.

[0045] According to the central air outlet structure 1000 of the present invention, on the one hand, by setting only one set of front blades 3 and only setting one second motor 5 to drive the set of front blades 3 to rotate, compared with the air outlet of the prior art which requires two motors to drive the front blades to rotate, the present invention only needs to set one motor to meet the usage requirements, thereby making the central air outlet structure 1000 of the present invention lower in cost; on the other hand, by setting the second motor 5 between any two adjacent housings 1 among the multiple housings 1, the installation space occupied by the second motor 5 is the space between the two adjacent housings 1, and the second motor 5 does not need to occupy additional space in the left and right directions, thereby helping to reduce the overall volume of the central air outlet structure 1000 of the present invention.

[0046] Optionally, the housing 1 is provided with multiple connecting posts, and the second motor 5 is connected to the connecting posts by bolts to be fixed to the housing 1.

[0047] According to some embodiments of the present invention, there is a receiving space between adjacent housings 1, and the second motor 5 is disposed on the middle housing 1 or in the middle receiving space. That is, when there is an odd number of housings 1, such as 3, the second motor 5 is installed on the middle housing 1; when there is an even number of housings 1, and the receiving space between the multiple housings 1 is an odd number, such as 4, there are 3 receiving spaces between the 4 housings 1, and the second motor 5 is located in the middle receiving space. In this way, on the one hand, the second motor 5 can be connected to the middle of the front row blades 3, and the front row blades 3 are not easily deformed when they swing under the drive of the second motor 5; on the other hand, it can make the center of gravity of the entire central air outlet structure 1000 of the present invention closer to the middle, thereby making the multiple housings 1 less prone to deformation.

[0048] According to some embodiments of the present invention, the central air outlet structure 1000 further includes a first motor 4. Multiple first motors 4 are respectively fixed to multiple housings 1, and are used to drive multiple sets of rear blades 2 to swing left and right respectively. It is understood that, in this way, the first motors 4 on the housings 1 near the left side can drive the rear blades 2 to swing to the left, the first motors 4 on the housings 1 near the right side can drive the rear blades 2 to swing to the right, and the first motors 4 on the housings 1 near the center can drive the rear blades 2 to remain in a centered position. This allows the central air outlet structure 1000 of the present invention to discharge air in different directions from different locations, better meeting user needs.

[0049] According to some embodiments of the present invention, the housings 1 on both sides of the second motor 5 are detachably connected. That is, at least the two housings 1 on both sides of the second motor 5 are designed separately, and the two housings 1 are independent components. When the second motor 5 is installed, the two housings 1 are not connected, so that there is sufficient installation space for the second motor 5 and the installation operation is convenient. After the second motor 5 is installed, the two housings 1 are connected and fixed so that the two housings 1 are connected as a whole for use.

[0050] According to some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the housings 1 on both sides of the second motor 5 are detachably connected via a pre-installation structure 6 and a reinforcing connection structure 7. It should be noted that using the pre-installation structure 6 and the reinforcing connection structure 7 to connect the two housings 1 on both sides of the second motor 5 ensures a stable connection between the two housings 1, preventing deformation due to uneven stress. When assembling the two housings 1 together, they can first be connected using the pre-installation structure 6, and then stably connected using the reinforcing connection structure 7. This not only strengthens the connection but also allows the pre-installation structure 6 to act as a pre-connection positioning element, facilitating the subsequent installation of the reinforcing connection structure 7.

[0051] Preferably, to ensure good use and connection effect, the upper and lower sides of the housing 1 on both sides of the second motor 5 are provided with pre-installation structure 6 and reinforcing connection structure 7.

[0052] Optionally, the housings 1 on both sides of the second motor 5 can be connected using only multiple pre-installation structures 6, with pre-installation structures 6 provided on both the upper and lower sides of the housings 1 on both sides of the second motor 5. Alternatively, the housings 1 on both sides of the second motor 5 can be connected using only multiple reinforcing connection structures 7, with reinforcing connection structures 7 provided on both the upper and lower sides of the housings 1 on both sides of the second motor 5.

[0053] According to some embodiments of the present invention, the pre-installation structure 6 is a snap-fit ​​structure, which is convenient and quick to connect.

[0054] According to some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the pre-installed structure 6 is located near the front end of the air duct opening, and the reinforcing connection structure 7 is a connecting bracket 701 located away from the front end of the air duct opening. The left and right ends of the connecting bracket 701 are connected to the housing 1 on both sides of the second motor 5 by bolts. Figure 1 As shown, since the front ends of two adjacent shells 1 have parts that directly fit together, the pre-installation structure 6 is used to pre-connect and fix the front ends of the two adjacent shells 1, so that the pre-positioning connection effect is better.

[0055] According to some embodiments of the present invention, such as Figure 2 , Figure 3 and Figure 7 As shown, the snap-fit ​​structure includes a plug 601 and a slot 602. The plug 601 and the slot 602 are respectively located on the front end of two adjacent housings 1 near the air duct opening. That is, one housing 1 is provided with a plug 601, and the other housing 1 is provided with a slot 602, and both the plug 601 and the slot 602 are located on the housing 1 near the front end. Figure 7 As shown, the insert 601 has a locking hole 6011, the slot 602 has a locking protrusion 6021, and the front and rear side walls of the slot 602 have first protrusions 6022. When the insert 601 is inserted into the slot 602, the locking protrusion 6021 is located in the locking hole 6011, and the first protrusion 6022 is used to limit the position of the front and rear sides of the insert 601. It can be understood that the locking structure including the insert 601 and the slot 602 can connect and limit the two adjacent housings 1.

[0056] According to some embodiments of the present invention, such as Figure 2 and Figure 8 As shown, the snap-fit ​​structure includes a first insert 603 and a second insert 604. The first insert 603 and the second insert 604 are respectively disposed in the middle of the housing 1 on both sides of the second motor 5. That is, the first insert 603 is disposed in the middle of one housing 1, and the second insert 604 is disposed in the middle of the other housing 1. Figure 8 As shown, the first insert 603 has a through groove 6031 running vertically, with the opening of the groove 6031 facing the second insert 604. Second protrusions 6032 are located on both the front and rear sides of the opening. The second insert 604 has an elongated third protrusion 6041. A protrusion 6042, which matches the through groove 6031, is located at the end of the third protrusion 6041 closest to the first insert 603. The through groove 6031 and the second protrusion 6032 together restrict the movement of the protrusion 6042 in the left-right direction. It can be understood that the snap-fit ​​structure including the first insert 603 and the second insert 604 can connect and limit the two housings 1.

[0057] Optionally, in the embodiments of the present invention, the two housings 1 may be provided with only a snap-fit ​​structure including a slot 602 and a plug 601, or only a snap-fit ​​structure including a first plug 603 and a second plug 604, or both a snap-fit ​​structure including a slot 602 and a plug 601 and a snap-fit ​​structure including a first plug 603 and a second plug 604 may be provided.

[0058] According to some embodiments of the present invention, such as Figure 4 As shown, the second motor 5 is connected to the front row of blades 3 via a crank-connecting rod mechanism 8 to drive the front row of blades 3 to swing up and down. Specifically, the crank-connecting rod mechanism 8 includes a crank 801, a transition connecting rod 802, and a connecting rod 803. One end of the crank 801 is rotatably connected to the rotor of the second motor 5, the other end of the crank 801 is rotatably connected to one end of the transition connecting rod 802, the other end of the transition connecting rod 802 is rotatably connected to one end of the connecting rod 803, and the other end of the connecting rod 803 is rotatably connected to a set of front row blades 3. Figure 4 As shown, the front end of the connecting rod 803 has multiple connecting teeth, which are rotatably connected to multiple front blades 3 in a one-to-one correspondence, so as to synchronously drive the multiple front blades 3.

[0059] According to some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, each set of rear blades 2 includes multiple rear blades 2 arranged in parallel. Each rear blade 2 is rotatably mounted on the upper fixing plate 201 and the lower fixing plate 202. The upper fixing plate 201 and the lower fixing plate 202 are respectively fixed to the upper side wall and the lower side wall of the housing 1. Figure 6 As shown, all blades in each group of rear blades 2 are connected by a connector 203. The rotor of the first motor 4 is connected to one of the rear blades 2 in each group of rear blades 2. When the first motor 4 drives one rear blade 2 to rotate, the rear blade 2 will drive the other rear blades 2 in the group of rear blades 2 to rotate synchronously through the connector 203.

[0060] According to some embodiments of the present invention, such as Figure 5 As shown, the central air outlet structure 1000 also includes a support plate 9. The support plate 9 is disposed on multiple housings 1 and located behind the front blades 3. The front end of the support plate 9 does not contact the front blades 3. When an external force is applied to the front blades 3, the front blades 3 will deform to a certain extent and then abut against the support plate 9, thus preventing the front blades 3 from undergoing significant deformation and being less prone to damage. For example, when there are two housings 1, the support plate 9 is located between two sets of rear blades 2 on two adjacent housings 1, and two support plates 9 are provided on the rear side of one front blade 3, spaced apart from each other.

[0061] The following is a specific example to illustrate the central air outlet structure 1000 of the present invention.

[0062] In this specific example, such as Figures 1 to 8 As shown, the central air outlet structure 1000 includes a housing 1, a rear row of blades 2, a front row of blades 3, a first motor 4, and a second motor 5.

[0063] There are two housings 1, which are arranged side by side. Each housing 1 defines a through-hole opening. The two housings 1 are detachably connected by a snap-fit ​​structure including a plug 601 and a slot 602, a snap-fit ​​structure including a first insert 603 and a second insert 604, and a reinforcing connection structure 7.

[0064] The insert 601 and the slot 602 are respectively located on the front end of the two housings 1 near the air duct opening. The insert 601 is provided with a locking hole 6011, and the slot 602 is provided with a locking protrusion 6021. The front and rear side walls of the slot 602 are provided with a first protrusion 6022. When the insert 601 is inserted into the slot 602, the locking protrusion 6021 is located in the locking hole 6011, and the first protrusion 6022 is used to limit the position of the front and rear sides of the insert 601.

[0065] The first insert 603 and the second insert 604 are respectively disposed in the middle of the two housings 1. The first insert 603 is provided with a through groove 6031 that runs vertically through the first insert 6031. The opening of the through groove 6031 faces the second insert 604. The front and rear sides of the opening are provided with second protrusions 6032. The second insert 604 is provided with a long strip-shaped third protrusion 6041. The end of the third protrusion 6041 near the first insert 603 is provided with a protrusion 6042 that matches the through groove 6031. The through groove 6031 and the second protrusion 6032 together restrict the movement of the protrusion 6042 in the left and right directions.

[0066] The reinforced connection structure 7 is a connecting bracket 701 located away from the front end of the air duct opening. The left and right ends of the connecting bracket 701 are connected to the two housings 1 respectively by bolts.

[0067] There are two sets of rear blades 2, which are vertically arranged in two air duct openings respectively. There are two first motors 4, which are fixed on two housings 1 respectively, and are used to drive the two sets of rear blades 2 to swing left and right respectively. Each set of rear blades 2 includes multiple rear blades 2 arranged in parallel. Each rear blade 2 is rotatably mounted on the upper fixing plate 201 and the lower fixing plate 202. The upper fixing plate 201 and the lower fixing plate 202 are respectively fixed on the upper side wall and the lower side wall of the housing 1. All blades in each set of rear blades 2 are connected by a connector 203. The rotor of the first motor 4 is connected to one of the rear blades 2 in each set of rear blades 2. When the first motor 4 drives one rear blade 2 to rotate, the other rear blades 2 will rotate synchronously through the connector 203.

[0068] There is one set of front blades 3, which are located in front of the two sets of rear blades 2 and are laterally positioned at the front end of the two air duct openings. There is one second motor 5, which is located between the two housings 1 and fixed to one of the housings 1, and is used to drive the front blades 3 to swing up and down. The second motor 5 is connected to the front blades 3 through a crank-connecting rod mechanism 8. The crank-connecting rod mechanism 8 includes a crank 801, a transition connecting rod 802, and a connecting rod 803. One end of the crank 801 is rotatably connected to the rotor of the second motor 5, and the other end of the crank 801 is rotatably connected to one end of the transition connecting rod 802. The other end of the transition connecting rod 802 is rotatably connected to one end of the connecting rod 803, and the other end of the connecting rod 803 is rotatably connected to one set of front blades 3.

[0069] The functional components in the central air outlet structure 1000 of this specific example have the same function as the corresponding functional components mentioned above, and will not be repeated here.

[0070] The central air outlet structure 1000 in this specific example has several advantages. First, by setting only one set of front blades 3 and only setting one second motor 5 to drive the front blades 3 to rotate, compared with the air outlets in the prior art that require two motors to drive the front blades to rotate, the present invention only needs to set one motor to meet the usage requirements, thereby making the central air outlet structure 1000 of the present invention lower in cost. Second, by setting the second motor 5 between any two adjacent housings 1 among the multiple housings 1, the installation space occupied by the second motor 5 is the space between the two adjacent housings 1. The second motor 5 does not need to occupy additional space in the left and right directions, thereby helping to reduce the overall volume of the central air outlet structure 1000 of the present invention.

[0071] Another object of the present invention is to provide an automobile including a central air vent structure 1000 according to an embodiment of the present invention.

[0072] Compared to existing technologies, the advantages of the automobile of the present invention are the same as those of the central air vent structure 1000 of the present invention, and will not be repeated here.

[0073] Another objective of this invention is to propose a control method based on the central air outlet structure 1000 and the air conditioner in this embodiment of the invention, wherein when the air conditioner is powered off, the front blades 3 of the central air outlet structure 1000, which are at any rotation angle, will continue to rotate to the position of the front end of the closed air duct.
