For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements.

[0034] Refer to the following Figures 1-4Describe the air outlet structure 100 according to an embodiment of the present utility model. The air outlet structure 100 can form a turbulent and delicate soft wind that blows onto the human body surface, improving the occupant's experience of the air outlet effect of the air conditioner outlet 11, and effectively preventing foreign objects from falling into the interior of the air outlet 11 and preventing human hands from accidentally touching the air guide vane 2, avoiding affecting the movement of the air guide vane 2 and causing its function to fail.

[0035] As Figures 1-4 shown, the air outlet structure 100 according to an embodiment of the present utility model includes: an air outlet housing 1, an air guide vane 2, a vane support panel 3, and a mounting grille 4.

[0036] The air outlet housing 1 is the main part of the air outlet structure 100, which forms an air outlet 11, that is, the air outlet housing 1 forms an open channel connecting the interior and the external environment of the air conditioner, namely the air outlet 11. Through the air outlet 11, air can smoothly flow from the interior of the air conditioner to the interior space of the vehicle, realizing air supply inside the vehicle. It can be understood that the shape and size of the air outlet 11 will affect the air outlet effect, and its design needs to maintain the smoothness of air flow and reduce the generation of noise.

[0037] The vane support panel 3 is connected to the air outlet housing 1. The air guide vane 2 is provided with a vane shaft 21, and the vane shaft 21 is rotatably installed on the vane support panel 3, and the air guide vane 2 is located at the air outlet 11.

[0038] Specifically, the vane support panel 3 is used to support and fixedly install the air guide vane 2, and is fixedly connected to the air outlet housing 1 to ensure the stability of the vane support panel 3, thereby ensuring the installation stability of the air guide vane 2, ensuring that the air guide vane 2 can rotate smoothly. At the same time, the vane support panel 3 needs to be able to withstand the wind pressure and vibration generated by the air supply.

[0039] The air guide vane 2 is used to adjust the air supply direction. The air guide vane 2 is installed on the air outlet housing 1 through the vane shaft 21 and is rotatable relative to the vane support panel 3. Thus, the air guide vane 2 can be rotated by rotating the vane shaft 21 to realize air sweeping, so as to flexibly control the air outlet direction at the air outlet 11, and further ensure that the air distribution inside the vehicle is more uniform and comfortable.

[0040] For example, as Figure 1 shown, the air guide vane 2 can perform left - right air sweeping, up - down air sweeping, etc. In the "free air sweeping" mode, the air guide vane 2 performs continuous sweeping from left to right and then from right to left, that is, left - right air sweeping.

[0041] Furthermore, the mounting grille 4 is connected to the air outlet housing 1, and the mounting grille 4 covers the outside of the air outlet 11.

[0042] Specifically, the shape and size of the installation grille 4 need to match those of the air outlet housing 1, so that the installation grille 4 can be stably connected to the air outlet housing 1. In practice, the installation grille 4 can be connected to the air outlet housing 1 by connection methods such as welding, bolt connection, snap connection, etc., to ensure the installation reliability of the installation grille 4 and prevent it from falling. The installation grille 4 can be constructed as a metal grille to improve its strength and prevent deformation.

[0043] Wherein, mesh holes are formed on the installation grille 4, and the air at the air outlet 11 can flow out smoothly through the mesh holes. And when passing through the installation grille 4, the air can be dispersed and reorganized by the grille, so as to form a turbulent and delicate soft wind that blows onto the surface of the occupant, improving the occupant's experience of the air outlet effect of the air conditioner outlet 11. At the same time, the setting of the installation grille 4 can prevent foreign objects in the outside world, such as dust, insects, etc. from entering the inside of the air outlet 11, thereby protecting the internal structure of the air conditioner from damage, and preventing users from directly contacting the rotating air guide blades 2 or other charged components, thus avoiding the occurrence of accidental injuries and affecting the movement of the air guide blades 2, resulting in the failure of their functions.

[0044] According to the air outlet structure 100 of the embodiment of the present utility model, by arranging the installation grille 4 to cover outside the air outlet 11, the air coming out from the air outlet 11 can be dispersed and reorganized, so as to form a turbulent and delicate soft wind that blows onto the surface of the occupant, improving the occupant's experience of the air outlet effect of the air conditioner outlet 11. At the same time, it can prevent foreign objects from entering the inside of the air outlet 11, thereby protecting the internal structure of the air conditioner from damage, and preventing users from directly contacting the rotating air guide blades 2 or other charged components, thus avoiding the occurrence of accidental injuries and affecting the movement of the air guide blades 2, resulting in the failure of their functions.

[0045] In some embodiments, an installation shaft section 211 is formed at the end of the blade shaft 21, and an installation shaft hole is formed on the blade support panel 3. The installation shaft section 211 is rotatably inserted into the installation shaft hole, and a fitting gap is formed between the outer peripheral wall of the installation shaft section 211 and the inner peripheral wall of the installation shaft hole.

[0046] Specifically, as Figure 1 and Figure 2 shown, installation shaft sections 211 are formed at the upper and lower ends of the blade shaft 21, and installation shaft holes that are adapted to the shape and size of the installation shaft sections 211 are formed on the upper and lower end faces of the blade support panel 3, so that the upper and lower ends of the blade shaft 21 can be smoothly, tightly and stably inserted into the installation shaft holes, realizing the connection between the blade shaft 21 and the blade support panel 3, and the installation shaft section 211 can rotate relative to the installation shaft hole inside, so that when the blade shaft 21 rotates, it can drive the air guide blade 2 to rotate flexibly relative to the blade support panel 3, realizing air sweeping.

[0047] Wherein, a fitting clearance is formed between the outer peripheral wall of the mounting shaft section 211 and the inner peripheral wall of the mounting shaft hole, that is, the outer peripheral wall of the mounting shaft section 211 and the inner peripheral wall of the mounting shaft hole are not completely in contact, but are spaced apart by a certain distance. In other words, the radial dimension of the mounting shaft hole is slightly larger than the radial dimension of the mounting shaft section 211. On the one hand, the setting of the fitting clearance enables the mounting shaft section 211 to rotate freely within the mounting shaft hole, thereby meeting the rotation requirements of the air guiding vane 2 during operation. On the other hand, it can also reduce the friction and wear between the mounting shaft section 211 and the mounting shaft hole to a certain extent, and extend the service life of the air guiding vane 2.

[0048] Exemplarily, the fitting clearance can be set to about 0.05 mm. When in the "free sweeping" mode, since the air guiding vane 2 is constantly rotating, the fitting clearance can ensure the stable rotation of the air guiding vane 2.

[0049] In actual design, the blade shaft 21 and the blade support panel 3 can be first fitted. In the "free sweeping" mode, the relative movement frequency between the blade shaft 21 and the mounting shaft hole is much higher than that of the manual air outlet 11. By first fitting the blade shaft 21 and the blade support, since the blade support panel 3 itself has a self-lubricating effect, it can ensure the smoothness of the fit between the blade shaft 21 and the mounting shaft hole to a certain extent, so as to avoid abnormal noises caused by the rough fit between the blade shaft 21 and the air outlet housing 1.

[0050] In some embodiments, an oil storage groove 212 is formed on the outer peripheral wall of the mounting shaft section 211, and the oil storage groove 212 extends along the circumferential direction of the mounting shaft section 211.

[0051] Specifically, when the air guiding vane 2 is in motion, some blade shafts 21 are relatively "tight" in fit with the mounting shaft hole, and some blade shafts 21 are relatively "loose" in fit with the mounting shaft. Therefore, lubricating grease needs to be applied between the blade shaft 21 and the mounting shaft hole. Since the blade shaft 21 is cylindrical, the applied lubricating grease is not easy to retain. Therefore, an oil storage groove 212 needs to be provided on the mounting shaft section 211 of the blade shaft 21 to store the lubricating grease, lubricate the blade shaft 21 and the mounting shaft hole, and retain the lubricating grease to the greatest extent to ensure the smooth movement between the two.

[0052] As Figure 2 shown, the outer peripheral wall of the mounting shaft section 211 is recessed to form the oil storage groove 212, and the oil storage groove 212 extends along the circumferential direction of the mounting shaft section 211 to form an annular groove. Lubricating grease can be stored in the groove. In practice, the oil storage groove 212 can be configured as a spherical groove. Such a setting can ensure that the lubricating grease is evenly distributed on the outer peripheral wall of the mounting shaft section 211, provide comprehensive lubrication for the blade shaft 21, extend the lubrication time, and thus ensure the stable and smooth rotation of the air guiding vane 2.

[0053] Among them, it should be noted that the oil storage tank 212 has a certain depth, and its depth is related to the capacity of the lubricating grease that can be stored. When the depth of the oil storage tank 212 is relatively deep, more lubricating grease can be stored, but the depth should not be too deep to avoid affecting the rigidity of the blade shaft 21. When the depth of the oil storage tank 212 is relatively shallow, less lubricating grease can be stored, and it can be flexibly designed according to the actual situation and requirements.

[0054] In some embodiments, for the width L of the oil storage tank 212 and the outer diameter D of the mounting shaft section 211, the following is satisfied: L / D ≤ 1 / 10.

[0055] That is to say, the proportional relationship between the width L of the oil storage tank 212 and the outer diameter D of the mounting shaft section 211 should satisfy the range of L / D ≤ 1 / 10. For example, the width L of the oil storage tank 212 can be set to 0.3, etc., and the outer diameter D of the mounting shaft section 211 can be set to 3, etc., or L / D can be set to 0.1, 0.09, 0.08, etc.

[0056] It can be understood that the width of the oil storage tank 212 determines the amount of lubricating grease it can store. If the L / D ratio is too large, although more lubricating grease can be stored, it will correspondingly reduce the rigidity and strength of the blade shaft 21, increase the resistance during the movement of the blade shaft 21, and thus affect the rotation of the air guiding blade 2. If the L / D ratio is small, it cannot provide enough lubricating grease to effectively extend the lubrication time, thereby affecting the lubrication effect.

[0057] By setting the proportional relationship of L / D within a reasonable range less than or equal to 1 / 10, not only is a certain oil storage space ensured, which is conducive to the uniform distribution of the lubricating oil on the outer peripheral wall of the mounting shaft section 211. When the blade shaft 21 moves, the lubricating oil can uniformly cover the contact surface with the mounting shaft hole as the mounting shaft section 211 rotates, thereby reducing friction and wear, improving the movement stability and smoothness of the air guiding blade 2, but also the rigidity and strength of the blade shaft 21 can be ensured, preventing it from breaking, etc., and thus improving its stability and reliability.

[0058] In some embodiments, there are multiple air guiding blades 2, that is, the air guiding blades 2 can be set to two, three, four or even more. Multiple air guiding blades 2 can work simultaneously to change the air supply direction, thereby improving the air supply efficiency.

[0059] And an air guiding channel 22 is formed between two adjacent air guiding blades 2, that is, the space area separated between two adjacent air guiding blades 2 is the air guiding channel 22. The air inside the air conditioner can pass through the air guiding channel 22 and flow out to the external environment under the guidance of the air guiding blades 2.

[0060] Specifically, as Figure 1As shown, there are five air guiding vanes 2 arranged above the air outlet housing 1 and five air guiding vanes 2 arranged below it, and an air guiding channel 22 is formed between two adjacent air guiding vanes 2.

[0061] The installation grille 4 is formed with air guiding mesh holes 41. That is to say, the installation grille 4 can be divided into multiple small holes by the grilles, namely the air guiding mesh holes 41. The air inside the air conditioner can flow out through the air guiding mesh holes 41. Among them, the opening width of the air guiding mesh holes 41, that is, the interval between the grilles, is smaller than the width of the air guiding channel 22. In this way, the flow rate and speed of the air flow can be adjusted to a certain extent. The smaller air guiding mesh holes 41 can limit the passing amount of the air flow, making the air more uniform and gentle when flowing out. And the grilles between adjacent air guiding mesh holes 41 can disperse the wind and form a turbulent soft wind blowing onto the surface of the occupant.

[0062] In actual design, the width of each grille can be set to 1.4 mm, etc., to ensure the strength of the installation grille 4 and at the same time ensure the air outlet effect.

[0063] In some embodiments, the installation grille 4 includes an upper region 42, a middle region 43, and a lower region 44 that are sequentially distributed in the up and down direction. The upper region 42 is formed with upper air guiding mesh holes 421, the middle region 43 is formed with middle air guiding mesh holes 431, and the lower region 44 is formed with lower air guiding mesh holes 441. The hole cross-sections of the upper air guiding mesh holes 421 and the lower air guiding mesh holes 441 are both larger than the hole cross-section of the middle air guiding mesh holes 431.

[0064] Specifically, as Figure 4 shown, the holes of the middle air guiding mesh holes 431 are the smallest, the upper air guiding mesh holes 421 and the lower air guiding mesh holes 441 are larger, and both extend in the up and down direction. In this way, the air outlet 11 can maintain a certain directivity in the up and down direction, which is beneficial to forming a more uniform air supply effect in the vertical direction, while the directivity in the left and right directions is slightly worse. Therefore, when performing air sweeping, a feeling of "no obvious wind feeling, but a feeling of coolness" can be formed when blowing on the human body surface, improving the comfort of the occupant.

[0065] In practice, when the upper air outlet channel (when working alone) blows downward and blows out through the upper air guiding mesh holes 421, its large hole cross-section can increase the air supply volume in the nearby area. And when the lower air outlet channel (when working alone) blows upward and blows out through the lower air guiding mesh holes 441, its large hole cross-section can also increase the air supply volume in the nearby area. When the upper air outlet channel and the lower air outlet channel work simultaneously, they will cover the middle region 43 and blow out through the middle air guiding mesh holes 431. Its small hole cross-section can make the wind more gentle. Thus, when the upper air guiding mesh holes 421, the middle air guiding mesh holes 431, and the lower air guiding mesh holes 441 blow out air simultaneously, the head, shoulders, neck, and abdomen of the occupant can all be blown by the wind, increasing the air supply uniformity, improving the blowing feeling, and reducing the discomfort felt by the human body.

[0066] Thus, by flexibly changing the hole cross-sectional sizes of the air guiding mesh holes 41 in different regions of the installation mesh cover 4, the speed, flow rate, and direction of air passing through the mesh holes are affected, thereby optimizing the air supply effect, making the air distribution inside the vehicle more uniform, forming a delicate gentle breeze, and enhancing the comfort of the occupants.

[0067] In some embodiments, the width of the lower end of the upper air guiding mesh hole 421 is configured to gradually decrease from top to bottom.

[0068] Specifically, as Figure 4 shown, the upper end of the upper air guiding mesh hole 421 is configured as a long strip, the lower end is configured as a triangle, and the width of the lower end is configured to gradually decrease from top to bottom. In this way, the air flow can flow downward more smoothly, and the phenomena of turbulence and eddy current can be reduced. At the same time, it can also enhance the uniformity of air supply to a certain extent, and avoid forming too strong an air flow or temperature difference at the top of the air supply area.

[0069] In some other embodiments, the middle air guiding mesh hole 431 is configured as a diamond-shaped hole.

[0070] Specifically, as Figure 4 shown, the middle part of the installation mesh cover 4 is concave, and two rows of diamond-shaped holes are provided. With this setting, the rigidity and strength of the installation mesh cover 4 can be enhanced, it can withstand a greater air flow pressure and is not easily deformed, and the air supply effect can be further homogenized.

[0071] In some other embodiments, the width of the upper end of the lower air guiding mesh hole 441 is configured to gradually decrease from bottom to top.

[0072] Specifically, as Figure 4 shown, the lower end of the lower air guiding mesh hole 441 is configured as a long strip, the upper end is configured as a triangle, and the width of the upper end is configured to gradually decrease from bottom to top. In this way, the air flow can be guided to flow upward more concentratedly, which is beneficial to forming a stronger air flow or temperature gradient at the bottom of the air supply area, and is also beneficial to reducing the turbulence phenomenon when the air flow passes through the lower air guiding mesh hole 441, and improving the stability and efficiency of air supply.

[0073] In some embodiments, the minimum width of the air guiding mesh hole 41 is H1, and it satisfies: 3.5 mm ≤ H1 ≤ 4.5 mm.

[0074] That is to say, the minimum width H1 of the air guiding mesh hole 41 can be set to 3.5 mm, 3.8 mm, 4.0 mm, 4.2 mm, 4.4 mm, 4.5 mm, etc. It can be understood that the smaller H1 is, that is, the smaller the minimum width of the air guiding mesh hole 41 is, the greater the resistance the air flow will encounter when passing through, which may lead to insufficient air supply volume, affecting the blowing feeling of the occupants and making it impossible to clearly feel the wind sensation.

[0075] The larger the H1 is, although the air flow throughability is enhanced, the uniformity of the air supply may be reduced because the larger air guide mesh holes 41 allow more air flow to pass directly through, reducing the dispersion and mixing of the air flow, that is, reducing the recombination of the air flow, thereby reducing the effect of forming gentle wind. At the same time, it also makes it easier for foreign objects to fall into the interior of the air inlet, affecting the movement of the air guide blade 2.

[0076] Therefore, by setting the minimum width H1 of the air guide mesh holes 41 within a reasonable range of 3.5 mm ≤ H1 ≤ 4.5 mm, the uniformity of the air supply and the air supply effect can be improved, ensuring smooth air flow through, and forming delicate gentle wind to blow onto the surface of the occupant.

[0077] In some embodiments, the air outlet structure 100 of the air conditioner further includes an electric driving member 5. The blade shaft 21 is connected with a blade transmission gear 23, and the output end of the electric driving member 5 is connected with a motor gear 51, and the motor gear 51 meshes with the blade transmission gear 23.

[0078] Specifically, the electric driving member 5 serves as a power source to provide power for the rotation of the blade shaft 21. When the electric driving member 5 drives the motor gear 51 to rotate, the motor gear 51 will drive the blade transmission gear 23 to rotate together, so that the rotation of the blade transmission gear 23 can drive the blade shaft 21 to rotate, realizing air sweeping.

[0079] Wherein, the air outlet housing 1 is provided with a first limiting block 12 and a second limiting block 13, and the motor gear 51 is provided with a limiting portion 511. The limiting portion 511 abuts against the first limiting block 12 when the air guide blade 2 rotates to the extreme position in the first direction, and the limiting portion 511 abuts against the second limiting block 13 when the air guide blade 2 rotates to the extreme position in the second direction.

[0080] Specifically, as Figure 3 shown, two limiting blocks are provided on the air outlet housing 1, namely the first limiting block 12 and the second limiting block 13. As shown in the up-down direction in the figure, the first limiting block 12 is located above, the second limiting block 13 is located below, and a limiting portion 511 protrudes from the left end of the motor gear 51, and the first limiting block 12, the second limiting block 13 and the limiting portion 511 are located on the same circular arc.

[0081] In this way, when the motor gear 51 rotates in the first direction, that is, rotates upward to the extreme position, it abuts against the first limiting block 12 to limit the motor gear 51 from continuing to rotate upward. When the motor gear 51 rotates in the second direction, that is, rotates downward to the extreme position, it abuts against the second limiting block 13 to limit the motor gear 51 from continuing to rotate downward. Therefore, by setting the limiting portion 511, the air guide blade 2 contacts the corresponding limiting block when rotating to the extreme position, thereby preventing the air guide blade 2 from further rotating, realizing precise control of the rotation angle of the air guide blade 2, and preventing the air guide blade 2 from being damaged due to excessive rotation.

[0082] Moreover, during the air-sweeping process of the air guide vane 2, its limiting portion 511 needs to continuously strike the first limiting block 12 and the second limiting block 13, which will cause abnormal noises. Therefore, the extreme position of the limiting portion 511 can be set to be 3° less than the positions of the first limiting block 12 and the second limiting block 13, so that it will not touch the limiting blocks, that is, it will not touch the air outlet 11 housing to generate impact abnormal noises.

[0083] The present utility model also proposes a vehicle.

[0084] The vehicle according to this embodiment is provided with the air outlet structure 100 of any one of the above embodiments. Among them, by arranging the installation mesh cover 4 to cover outside the air outlet 11, the air coming out from the air outlet 11 can be scattered and recombined, so as to form a turbulent and delicate soft wind blowing onto the surface of the occupant, improving the experience of the occupant on the air outlet effect of the air conditioner outlet 11. At the same time, it can prevent foreign objects from entering the inside of the air outlet 11, thereby protecting the internal structure of the air conditioner from damage, and can prevent users from directly contacting the rotating air guide vane 2 or other charged components, thereby avoiding the occurrence of accidental injuries and affecting the movement of the air guide vane 2, resulting in the failure of its function.
