Description

Technical Field

[0001] This application relates to the field of automotive air conditioning technology, and more particularly to an air outlet blade, an air outlet assembly, and a vehicle. Background Technology

[0002] As a core component of the vehicle's air conditioning system and its interaction with the cabin environment, the air vent assembly performs a crucial function: it delivers processed cold and hot air to different areas of the cabin according to preset directions and flow rates, thereby precisely regulating the interior temperature, humidity, and air circulation to create a comfortable driving and riding environment for passengers. Furthermore, the harmonious design and ease of operation of the air vents directly impact the overall quality of the vehicle's interior and the user experience, making them an important interior component that combines functionality and aesthetics.

[0003] Most existing vehicle air vent blades adopt a one-piece design, with the blades themselves typically injection molded from a single material (such as ABS plastic). The blade body is directly connected to the air vent frame via a pivot or clip, and the blades achieve synchronous adjustment of airflow direction through a linkage mechanism. While this design can meet basic airflow adjustment needs, it has significant limitations in terms of structural stability and durability.

[0004] In actual use, air vent blades face multiple risks of damage. Firstly, some users habitually clamp external devices such as phone holders onto the blades. The continuous clamping force of the holder keeps the blades under constant stress, and the vibrations and bumps during vehicle movement further exacerbate the deformation, easily leading to cracks or even breakage over time. Secondly, if foreign objects such as coins or cards accidentally fall into the air vent and become stuck between the blades while the vehicle is parked, the blades may break due to abnormal stress when the driver or passengers attempt to adjust them. Furthermore, during daily use or vehicle maintenance, accidental impacts from tools or other objects to the air vent blades can directly cause deformation, cracking, or even breakage. More importantly, because the blades and air vent frame are designed as a single unit, once a blade is damaged, it is often impossible to replace it individually; the entire air vent assembly must be replaced. This undoubtedly increases repair costs significantly, placing an unnecessary financial burden on users. Utility Model Content

[0005] This application provides an air outlet blade, an air outlet assembly, and a vehicle, which aims to solve the problem of excessive cost caused by the need to replace the entire blade when it is damaged. By adopting a split modular design, the replacement plate can be replaced individually, thereby effectively reducing maintenance and replacement costs.

[0006] To achieve the above objectives, this application adopts the following technical solution: This application provides an air outlet blade, comprising: A blade base is provided with a receiving cavity; the receiving cavity extends through the blade base along the thickness direction; the receiving cavity extends through one side of the blade base along the width direction; along the length direction of the blade base, the portions of the blade base located on both sides of the receiving cavity are protrusions, and the protrusions facing the receiving cavity are provided with a first slot. A replacement plate is inserted into the receiving cavity along the width direction of the blade base; a second slot is provided at each of its two ends; when the replacement plate is fully inserted into the receiving cavity, the first slot and the second slot correspond to each other and are connected. A locking pin, which can be embedded in the first slot and the corresponding second slot.

[0007] In the above embodiments, this application achieves a detachable structure for the replacement plate by interlocking the receiving cavity of the blade base with the replacement plate, which facilitates the individual replacement of the replacement plate later (e.g., due to wear, functional upgrades, or appearance changes), thereby reducing maintenance costs. The design of the replacement plate being interlocked with the blade base ensures its stability in the thickness and length directions. The structure of the locking pin embedded in the corresponding slot can stably lock the relative position of the replacement plate and the blade base in the width direction. The above design can effectively prevent the replacement plate from loosening or falling off during use (e.g., vehicle vibration, external force contact), improving the stability of the overall structure. In addition, the through design of the receiving cavity provides ample operating space for the disassembly and assembly of the replacement plate, with a reasonable structural layout and strong adaptability.

[0008] In some embodiments of this application, the ratio of the length of the replacement plate to the length of the blade base is 60% to 80%.

[0009] In the above embodiments, the replacement plate is limited to 60% to 80% of the blade base length. This ensures that the replacement plate has sufficient functional areas (such as clamping, guiding, decoration, etc.) to meet actual usage requirements, while avoiding the structural strength of the blade base being weakened due to the replacement plate being too long. In particular, it avoids excessive weakening of the support capacity of the protrusions on both sides of the receiving cavity, thus balancing functionality and structural stability.

[0010] In some embodiments of this application, the protrusion is provided with a groove on the side facing the receiving cavity, and the two sides of the replacement plate are respectively provided with sliders that match the groove; during assembly, the sliders can be embedded in the groove, and the replacement plate achieves a detachable connection with the blade base through the cooperation of the two.

[0011] In the above embodiments, this application provides a guiding function for the insertion of the replacement plate by cooperating with the sliding block of the protrusion and the slider of the replacement plate, making the disassembly and assembly process smoother and more convenient. At the same time, while ensuring the ease of installation, it can effectively ensure the stability of the replacement plate in the thickness and length directions—the cooperation between the sliding block and the slider can limit the displacement of the replacement plate in the thickness direction, and the two protrusions limit the displacement of the replacement plate in the length direction. In addition, the locking pin restricts the width direction of the replacement plate, further improving the overall stability of the connection and reducing shaking during use, which is suitable for scenarios that require frequent disassembly and assembly of the replacement plate.

[0012] In some embodiments of this application, the replacement plate is provided with sliding grooves on both sides, and the protrusion is provided with a slider that matches the sliding groove on the side facing the receiving cavity; during assembly, the slider can be embedded in the sliding groove, and the replacement plate is detachably connected to the blade base through the cooperation of the two.

[0013] In some embodiments of this application, the groove is a dovetail groove.

[0014] In the above embodiments, this application defines the slide groove as a dovetail groove. By utilizing the structural characteristics of the dovetail groove, which has a narrow opening and a wide bottom, it can effectively prevent the slider from detaching along the direction perpendicular to the slide groove, significantly improving the connection strength and anti-loosening ability between the replacement plate and the blade base. It is especially suitable for scenarios with high requirements for structural stability in dynamic environments (such as vehicle driving).

[0015] In some embodiments of this application, the replacement plate has a second arc-shaped end on the side opposite to the blade base, and the protrusion has a first arc-shaped end on one side corresponding to the second arc-shaped end.

[0016] In the above embodiments, the arc-shaped end of this application can reduce sharp edges compared with the right-angle structure, reducing the risk of users being scratched when touching it. It is especially suitable for scenarios where people are likely to come into contact with it, such as vehicles, thus improving the safety of use. In addition, the arc-shaped end can disperse stress concentration, preventing the end from cracking or being damaged due to long-term stress (such as clamping of external components or airflow impact), thus extending the service life of the blade.

[0017] In some embodiments of this application, the main body of the blade base and the main body of the replacement plate are both integrally molded from fiber-reinforced thermoplastic composite material, and both surfaces are integrally covered with an elastomer friction layer.

[0018] In the above embodiments, the blade base and replacement plate of this application are made of fiber-reinforced thermoplastic composite material (such as PA66 + glass fiber). This material has high strength, high rigidity, and excellent weather resistance, which can meet the structural load-bearing requirements of the air outlet blades and effectively support external components and resist airflow impact. Both surfaces are covered with an elastomer material (such as TPU), which not only improves surface wear resistance and increases the coefficient of friction to prevent external components from sliding, but also reduces abnormal noise caused by vibration through elastic buffering. This rigid-flexible composite structure achieves dual protection against dynamic and static loads, taking into account both structural performance and user comfort.

[0019] In some embodiments of this application, a first rotating shaft is provided at one end of the blade base, and a second rotating shaft is provided at the other end of the blade base away from the first rotating shaft, wherein the first rotating shaft and the second rotating shaft are coaxial; A connecting block is connected to one end of the second rotating shaft away from the blade base. A connecting shaft is provided on the side of the connecting block opposite to the second rotating shaft. The connecting shaft is not coaxial with the second rotating shaft.

[0020] In addition, this application also provides an air outlet assembly, including an air outlet frame and at least one air outlet blade disposed within the air outlet frame.

[0021] In addition, this application also provides a vehicle, including a vehicle body and a plurality of air outlet blades or a plurality of air outlet assemblies disposed within the vehicle body.

[0022] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0030] As a core component of the vehicle's air conditioning system and its interaction with the cabin environment, the air vent assembly bears a crucial mission: it delivers treated hot or cold air to various areas of the cabin according to preset directions and flow rates, precisely regulating the temperature, humidity, and air circulation within the vehicle to create a comfortable environment for passengers. Currently, most vehicle air vent blades are a one-piece design, typically injection-molded from a single material such as ABS plastic; the blades are directly connected to the vent frame via a pivot or clip, and the airflow direction is synchronized between the blades through a linkage mechanism. While this design meets basic airflow adjustment needs, it has significant shortcomings in structural stability and durability, making the blades susceptible to damage in various scenarios.

[0031] In actual use, the air outlet blades face various risks of damage. Accidental intrusion of foreign objects into the air outlet, excessive force when adjusting the blade angle, accidental impacts to the air outlet blades, and clamping of external devices can all easily lead to blade damage. Because the blades and frame are designed as a single unit, damage often necessitates replacing the entire air outlet assembly, significantly increasing repair costs. Among these, damage caused by clamping external devices is the most common. Some users habitually clamp external devices such as phone holders onto the blades, which places excessive stress on them. The continuous clamping force of the holder keeps the blades under constant stress, and combined with repeated deformation from driving bumps, this can easily cause the blades to loosen, crack, or even break.

[0032] Based on this, this application proposes an air outlet blade, assembly, and vehicle. By providing a through-hole receiving cavity 112 on the blade base 110, a replacement plate 120 can be inserted into the receiving cavity 112. The plate is guided and limited by the sliding groove 111b and the slider 122, and then locked by the slot and locking pin 130, forming a modular design. This structure allows for the individual replacement of the replacement plate 120, thereby effectively reducing maintenance and replacement costs.

[0033] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0034] As attached Figures 1 to 16 As shown in an illustrative embodiment of this application, the air outlet blade 100 includes a blade base 110, and the blade base 110 is provided with a receiving cavity 112. The receiving cavity 112 penetrates the blade base 110 along the thickness direction and penetrates one side of the blade base 110 along the width direction; specifically, a notch is provided on one side of the blade base 110.

[0035] In addition, the width direction of the blade base 110 is set as the X-axis, the length direction of the blade base 110 is set as the Y-axis, and the thickness / height direction of the blade base 110 is set as the Z-axis. This setting will be used in the following text and will not be repeated.

[0036] In some embodiments, such as Figure 6 As shown, the projection shape of the blade base 110 on the XY plane is roughly concave.

[0037] In some embodiments, along the length direction (Y-axis direction) of the blade base 110, the portions of the blade base 110 located on both sides of the receiving cavity 112 are protrusions 111, and a first slot 111e is provided on the side of the protrusions 111 facing the receiving cavity 112.

[0038] In some embodiments, the first slots 111e of the two protrusions 111 both face the receiving cavity 112, and the two first slots 111e are located on the same straight line, which is parallel to the length direction of the blade base 110.

[0039] In some embodiments, the projection shape of the protrusion 111 in the XY plane is generally rectangular.

[0040] In some embodiments, the air outlet blade 100 includes a replacement plate 120, the replacement plate 120 having a rectangular shape projected onto the XY plane (e.g., ...). Figure 10 , 12 As shown in the figure, and adapted to the shape of the receiving cavity 112; the replacement plate 120 is detachably inserted into the receiving cavity 112 along the width direction (X-axis direction) of the blade base 110. Through this insertion connection method, the replacement plate 120 can be constrained in the Y-axis and Z-axis directions, thereby ensuring the stability of the replacement plate 120 in the Y-axis and Z-axis directions.

[0041] In some embodiments, such as Figure 11 As shown, along the length direction (Y-axis direction) of the blade base 110, the two ends of the replacement plate 120 are respectively provided with second slots 123; when the replacement plate 120 is fully inserted into the receiving cavity 112, the first slot 111e and the second slot 123 correspond to each other and are connected.

[0042] In some embodiments, the first slot 111e and the second slot 123 are mated to form a complete slot. The projection shape of the slot in the XY plane can be flexibly designed, including but not limited to rectangle, circle, triangle, trapezoid or other polygons, as long as the locking pin 130 can be stably embedded and achieve the positioning function.

[0043] In some embodiments, such as Figure 5As shown, the air outlet blade 100 includes two locking pins 130. The locking pins 130 mate with a slot composed of a first slot 111e and a corresponding second slot 123. The locking pins 130 can be embedded into the slot composed of the first slot 111e and the corresponding second slot 123. The locking pins 130 are used to constrain the replacement plate 120 in the X-axis direction, ensuring the stability of the replacement plate 120 in the X-axis direction. Together with the previous constraints in the Y and Z-axis directions, they complete the all-round constraint of the replacement plate 120 in the X, Y, and Z directions, achieving the effect of firmly fixing the replacement plate 120 to the blade base 110.

[0044] In some embodiments, the projection shape of the locking pin 130 in the XY plane can be flexibly designed, including but not limited to rectangle, circle, triangle, trapezoid or other polygon, as long as the locking pin 130 can be stably embedded and achieve the positioning function.

[0045] In some embodiments, the dimensions of the locking pin 130 in the length, width, and height directions match the dimensions of the slot formed by the first slot 111e and the corresponding second slot 123 in the same three directions.

[0046] In some embodiments, the dimensions of the locking pin 130 in the length, width and height directions are slightly larger than the dimensions of the slot formed by the first slot 111e and the corresponding second slot 123 in the same three directions; that is, the locking pin 130 is embedded in the slot formed by the first slot 111e and the corresponding second slot 123 in an interference fit manner.

[0047] Furthermore, the locking pin 130 is made of elastic materials such as rubber, and its elastic properties make it easy to assemble into the slot composed of the first slot 111e and the corresponding second slot 123 in an interference fit state.

[0048] It is worth noting that when the air vent blade 100 is assembled onto the vehicle, both the first slot 111e and the second slot 123 face the roof. This design can use gravity to assist in locking, effectively preventing the locking pin 130 from accidentally coming off when the vehicle is bumpy.

[0049] In some embodiments, the ratio of the length of the replacement plate 120 along the Y-axis (length direction) to the length of the blade base 110 along the same direction (Y-axis direction) is 60% to 80%. If this ratio is less than 60%, the size of the replacement plate 120 will be too small, failing to meet practical usage requirements such as phone holder clamping. In this case, the phone holder may be directly clamped onto the blade base 110, which not only violates the original intention of the modular design of this application but may also cause damage to the blade base 110. If the ratio is greater than 80%, the size of the blade base 110 will be too small, and the replacement plate 120 will be too long, weakening the structural strength of the blade base 110 and affecting the overall stability.

[0050] By controlling the ratio within the range of 60% to 80%, the functionality of the replacement plate 120 is ensured. As a component that directly contacts external devices (such as mobile phone holders), the replacement plate 120 needs to have sufficient length to stably support the external devices. A length ratio of over 60% can provide ample clamping space for the external devices, ensuring their stability after installation and preventing the external devices from shaking or falling off due to insufficient contact area. On the other hand, the structural integrity of the blade base 110 is also taken into account. The blade base 110 needs to provide a stable support and installation foundation for the replacement plate 120. Retaining a certain length can ensure the structural strength of the base itself and prevent the connection strength between the base and the air outlet frame 500 from being weakened due to the replacement plate 120 having an excessively large proportion, ensuring that the entire blade structure is not easily deformed or damaged during long-term use.

[0051] Preferably, the ratio of the length of the replacement plate 120 to the length of the blade base 110 is 80%. This ratio is at the upper limit of the reasonable range of 60% to 80%, which allows the blade base 110 to retain 20% of its length to ensure sufficient structural strength, while also allowing the length of the replacement plate 120 to reach its relative maximum value, thereby maximizing its contact area with external devices (such as mobile phone holders) and fully meeting the functional requirements of stably supporting external devices.

[0052] Preferably, the ratio of the length of the replacement plate 120 to the length of the blade base 110 is 60%. This ratio is at the lower limit of the reasonable range of 60% to 80%, which can both reserve more sufficient length for the blade base 110 (accounting for 40%), thereby maximizing the structural strength of the base, effectively enhancing the deformation resistance and durability of the entire blade structure, and providing a solid and reliable support foundation for the replacement plate 120; and ensure that the replacement plate 120 has the length to meet the basic functional requirements, which is sufficient to support external devices such as mobile phone holders and provide a stable clamping space.

[0053] In some embodiments, such as Figure 5 As shown, the protrusion 111 of the blade base 110 is provided with a groove 111b on the side facing the receiving cavity 112, and the two sides of the replacement plate 120 are respectively provided with sliders 122 that match the groove 111b; during assembly, the sliders 122 can be embedded in the groove 111b along the X-axis direction (width direction of the blade base 110), and the replacement plate 120 can be detachably connected to the blade base 110 through the sliding engagement of the groove 111b and the sliders 122.

[0054] Furthermore, the first slot 111e is disposed on the slide groove 111b, and the second slot 123 is disposed at the matching position of the slider 122; when the replacement plate 120 is fully inserted into the receiving cavity 112 along the X-axis direction (the width direction of the blade base 110), and the slider 122 and the slide groove 111b complete the sliding engagement, the first slot 111e and the second slot 123 will be precisely aligned and form a through complete slot, realizing the corresponding connection and communication between the two.

[0055] In some embodiments, not shown in the figures, the replacement plate 120 is provided with grooves 111b on both sides, and the protrusion 111 of the blade base 110 is provided with a slider 122 that matches the groove 111b on the side facing the receiving cavity 112. During assembly, the slider 122 can be embedded in the groove 111b along the X-axis direction (width direction of the blade base 110). The replacement plate 120 achieves a detachable connection with the blade base 110 through the sliding engagement of the groove 111b and the slider 122.

[0056] In some embodiments, the groove 111b is a dovetail groove.

[0057] The dovetail groove is a commonly used connecting groove in mechanical structures, named for its cross-sectional shape resembling the tail of a swallow. Its cross-section has unique characteristics: the width of the groove opening 111d is smaller than the width of the groove bottom 111c, forming a wedge-shaped structure. This structure, with its self-locking property, can withstand certain lateral and vertical forces, thus achieving a strong and stable connection.

[0058] In some embodiments, the replacement plate 120 has a second arcuate end 121 on the side away from the blade base 110. The second arcuate end 121 extends from one end of the replacement plate 120 to the other end along the length direction (Y-axis direction) of the replacement plate 120. The cross-section of the second arcuate end 121 in the XZ plane is arcuate. Specifically, its arcuate profile is a curved surface formed along the X-axis and Z-axis directions. Preferably, the cross-section of the second arcuate end 121 in the XZ plane is semi-circular. The arcuate shape protrudes to the side away from the blade base 110.

[0059] In some embodiments, a first arcuate end 111a corresponding to the second arcuate end 121 is provided on one side of the protrusion 111. The first arcuate end 111a extends from one end of the protrusion 111 to the other end along the length direction (Y-axis direction) of the blade base 110. The cross-section of the first arcuate end 111a in the XZ plane is arcuate. Specifically, its arcuate profile is a curved surface shape formed along the X-axis and Z-axis directions. Preferably, the cross-section of the first arcuate end 111a in the XZ plane is semi-circular.

[0060] The first arc-shaped end 111a and the second arc-shaped end 121 are designed to avoid stress concentration and to prevent sharp edges from scratching the user.

[0061] In some embodiments, the main body of the blade base 110 and the main body of the replacement plate 120 are both integrally molded from fiber-reinforced thermoplastic composite materials, and both surfaces are integrally covered with an elastomer friction layer. The process principle is based on two-color injection molding technology: by injection molding, an elastomer material is integrally coated onto the surface of the main body composed of composite materials to form an elastomer friction layer. This increases the friction of the contact surfaces to prevent loosening of the connecting parts and utilizes the properties of the elastomer to reduce abnormal noise caused by rigid contact between parts. Two-color injection molding technology is a special injection molding process that uses two barrels of an injection molding machine and a set of molds to sequentially inject and fuse two different materials or colors of plastic into the same mold, forming a product with the characteristics of both materials or colors. Two-color injection molding technology is widely used in the industrial field.

[0062] This design effectively solves two problems: first, it improves dynamic stability, preventing the phone holder from falling off due to inertia when the vehicle accelerates or brakes suddenly, thus ensuring ease of use; second, it reduces noise interference. By using an elastomer friction layer to buffer the rigid contact between the holder and the blade, it reduces noise generated when the vehicle vibrates, thereby avoiding distracting the driver, reducing the risk of fatigue driving, improving the passenger experience, and enhancing the overall quality of the vehicle.

[0063] Fiber-reinforced thermoplastic composites are composite polymer materials formed by incorporating glass fibers, carbon fibers, and other reinforcing fibers into thermoplastic resin as the matrix, and are widely used in industrial fields. Thermoplastic resin has the characteristics of being meltable and malleable when heated and solidified upon cooling, while reinforcing fibers significantly improve the mechanical properties of the material, such as strength, rigidity, and wear resistance, making the overall performance of the composite material superior to that of a single resin.

[0064] Common fiber-reinforced thermoplastic composites include: glass fiber reinforced polyamide 66, glass fiber reinforced polypropylene composites, carbon fiber reinforced polyether ether ketone composites, glass fiber reinforced polybutylene terephthalate composites, carbon fiber reinforced polyamide composites, basalt fiber reinforced polyethylene composites, etc.

[0065] Elastomers are a class of polymeric materials with significant elastic deformation capabilities. Their core characteristics are: they can undergo large deformations under external forces and quickly return to their original shape after the force is removed. They also possess a certain degree of toughness and wear resistance, making them widely used in industrial fields. Common elastomer materials include thermoplastic polyurethane (TPU), thermoplastic polyolefin (TPO), thermoplastic polyester elastomer (TPEE), natural rubber (NR), nitrile rubber (NBR), chloroprene rubber (CR), and silicone rubber (SR).

[0066] Preferably, the main body of the blade base 110 and the main body of the replacement plate 120 are both made of PA66+30% glass fiber composite material (i.e., polyamide 66 as the matrix, with 30% glass fiber added), and the material of the elastomer friction layer is TPU.

[0067] In some embodiments, a first rotating shaft 140 is provided at one end of the blade base 110, and a second rotating shaft 150 is provided at the other end of the blade base 110 away from the first rotating shaft 140, wherein the first rotating shaft 140 and the second rotating shaft 150 are coaxial; The end of the second rotating shaft 150 away from the blade base 110 is connected to a connecting block 160. A connecting shaft 170 is provided on the side of the connecting block 160 away from the second rotating shaft 150. The connecting shaft 170 is not coaxial with the second rotating shaft 150. The second rotating shaft 150, the connecting block 160 and the connecting shaft 170 together form a Z-shaped structure. The function of this structure is to cooperate with the linkage mechanism of the air outlet assembly, so that the synchronous adjustment of all blades can be achieved by adjusting a single blade.

[0068] This application provides an air outlet assembly, which includes an air outlet frame 500, a linkage plate 300, a fixing plate 400, and at least one of the aforementioned air outlet blades 100. The components cooperate with each other to achieve the air outlet direction adjustment function.

[0069] The fixed plate 400 has a number of shaft holes arranged at even intervals. The number of shaft holes corresponds exactly to the number of air outlet blades 100. The first rotating shaft 140 of each air outlet blade 100 can be rotatably assembled in the corresponding shaft hole. This connection structure provides a stable rotation support point for the air outlet blades 100, ensuring that the blades will not deviate during rotation.

[0070] The linkage plate 300 has several through holes, the number of which is equal to the number of air outlet blades 100. The connecting shaft 170 of each air outlet blade 100 passes through the corresponding through hole, and the connecting shaft 170 is rotatably connected to the through hole. Specifically, the outer diameter of the connecting shaft 170 is slightly smaller than the inner diameter of the through hole, allowing the connecting shaft 170 to rotate flexibly within the through hole. At the same time, the connecting shaft 170 is provided with a retaining groove, which forms a certain limiting fit with the edge of the through hole, preventing the connecting shaft 170 from falling out of the through hole without affecting the relative rotation between the two.

[0071] The fixing plate 400 is fixedly installed on one side of the air outlet frame 500, providing a stable installation base for the entire blade assembly; the other side of the air outlet frame 500 is provided with several through holes, and the second rotating shaft 150 of each air outlet blade 100 is rotatably set in the corresponding through hole, which together with the first rotating shaft 140 constitutes the dual-axis rotation support structure of the air outlet blade 100.

[0072] This design allows the outlet blades 100 to rotate stably around the axes of the first and second rotating shafts 140 and 150, thereby adjusting the airflow direction. The key to the synchronous rotation of the outlet blades 100 lies in the transmission function of the linkage plate 300: when one outlet blade 100 is rotated, its connecting shaft 170 rotates within the corresponding through hole of the linkage plate 300. Simultaneously, through the friction and limiting action between the connecting shaft 170 and the through hole, the linkage plate 300 as a whole moves upward or downward accordingly. The movement of the linkage plate 300 is then transmitted through other through holes to the connecting shafts 170 of the other connected outlet blades 100, thus causing all outlet blades 100 to rotate synchronously. Ultimately, adjusting one blade allows for the simultaneous adjustment of all blades, ensuring the consistency and convenience of outlet airflow direction adjustment.

[0073] In some embodiments, such as Figures 14-16 As shown, the air outlet assembly also includes an active blade 200, which is equipped with a lever. One end of the active blade 200 is connected to a first rotating shaft 140, and the other end of the active blade 200, away from the first rotating shaft 140, is connected to a second rotating shaft 150. The first rotating shaft 140 and the second rotating shaft 150 are coaxial. A connecting block 160 is connected to the end of the second rotating shaft 150 away from the active blade 200. A connecting shaft 170 is located on the side of the connecting block 160 opposite to the second rotating shaft 150, and the connecting shaft 170 is not coaxial with the second rotating shaft 150. Furthermore, the active blade 200 is assembled into the air outlet frame 500 in the same way as the air outlet blade 100, and will not be described further.

[0074] This application provides a vehicle, including a vehicle body and a plurality of air outlet blades 100 or a plurality of air outlet assemblies disposed within the vehicle body.

[0075] In some embodiments, the air vent assembly is located on the dashboard of the vehicle body.
