Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide an electric air outlet mechanism for automatically adjusting wind direction and air volume.

[0004] In a first aspect, an electric air outlet mechanism is provided, comprising: an air guide panel, an air outlet front housing, an air guide outer cover, an upper blade electric assembly, an air guide inner cover, a lower blade electric assembly and an air outlet rear housing;

[0005] The air guide panel, the air outlet front shell and the air outlet rear shell are sequentially connected to form an outer shell cover, and the middle part of the outer shell cover constitutes an air outlet inner cavity;

[0006] The air guide outer cover is connected to the air guide inner cover to form an inner shell;

[0007] The inner shell is arranged in the outer shell so that an upper blade installation cavity is formed between the upper and lower surfaces of the inner shell and the outer shell;

[0008] The upper blade electric assembly is installed in the upper blade installation cavity;

[0009] The lower blade electric assembly is arranged in the air outlet rear shell and connected to the air guide inner cover.

[0010] Furthermore, the air guide cover includes an upper wall plate and a lower wall plate, and a connecting plate connecting the upper wall plate and the lower wall plate; the upper wall plate and the lower wall plate are configured as inclined air guide wall plates, so that the transverse cross-sectional view of the air guide cover is a trapezoid with a smaller front and a larger rear.

[0011] Furthermore, the angle between the wind guiding inclined wall plate and the horizontal direction is 32-33°.

[0012] Furthermore, the air guide inner cover is arranged to be in an arc shape with a middle portion convex toward the rear shell body of the air outlet.

[0013] Furthermore, the transverse cross-sectional view of the middle portion of the air guide inner cover is C-shaped.

[0014] Further, it also includes a blade cushioning sponge;

[0015] The blade buffer sponge is arranged on the inner surface of the shell behind the air outlet.

[0016] Furthermore, the wind guide panel is provided with reinforcing ribs.

[0017] Furthermore, the reinforcing ribs are honeycomb-shaped.

[0018] In a second aspect, an air conditioning system is provided, characterized in that it comprises two electric air outlet mechanisms as described in the above technical solution;

The above schematic diagram is not intended to be an actual scale of an actual product.

[0036] like Figures 1 to 3 As shown, an electric air outlet mechanism of an embodiment of the utility model includes: an air guide panel 1, an air outlet front shell 2, an air guide outer cover 3, an upper blade electric assembly 4, an air guide inner cover 5, a lower blade electric assembly 6 and an air outlet rear shell 7.

[0037] Among them, the air guide panel 1 is located in the front part of the air outlet mechanism, which is the external visible part of the air outlet mechanism and is usually matched with the vehicle interior design. There are two sheet-like limiting ribs on the upper and lower bottom surfaces of the rear side of the air guide panel 1, and the limiting ribs have assembly guide slopes. The air outlet decorative panel is provided with a snap-on structure adapted to the limiting ribs to form an interlocking in the upper and lower directions, which helps to accurately control the assembly of the air guide panel 1 and the decorative panel, reduce the assembly surface difference, improve the overall matching quality and avoid abnormal noise during driving. Iron buckle holes are provided on both sides of the air guide panel 1. Correspondingly, an iron buckle adapted thereto is provided on the air outlet decorative panel. The connection between the air guide panel 1 and the air outlet decorative panel is achieved by the adaptive connection between the iron buckle and the iron buckle hole.

[0038] Reinforcement ribs 10 are provided on the outer surface of the air guide panel 1. Specifically, the reinforcement ribs 10 are designed to be honeycomb-shaped to enhance their rigidity and prevent deformation under hot and cold working conditions.

[0039] The upper and lower bottom surfaces of the front side of the air guide panel 1 each have two "T"-shaped clamping feet for connecting to the air outlet front shell 2.

[0040] The air outlet front housing 2 is provided with a mounting hole adapted to the "T"-shaped clamping foot, which is used to connect the air outlet front housing 2 and the air guide panel 1 through the "T"-shaped clamping foot adapting to the mounting hole. The rear part of the air outlet front housing 2 is also provided with a clamping slot.

[0041] The air outlet rear housing 7 is trumpet-shaped. A clamping protrusion adapted to the clamping slot is provided at the edge of the front portion thereof, and the connection between the air outlet rear housing 7 and the air outlet front housing 2 is achieved through the adaptive connection between the clamping protrusion and the clamping slot.

[0042] The air outlet sealing sponge 11 is pasted on the circumference of the rear part of the air outlet rear shell 7 for connecting with the air duct. Specifically, a limiting strip rib is provided on the outer surface of the rear part of the air outlet rear shell 7. The air outlet sealing sponge 11 is sleeved on the rear part of the air outlet rear shell 7, and the position of the air outlet sealing sponge 11 is limited by the limiting strip rib.

[0043] Through the above structure, the air guide panel 1, the air outlet front shell 2 and the air outlet rear shell 7 are sequentially connected to form an outer shell, and the middle of the outer shell forms the air outlet cavity. The modular design can improve production efficiency and reduce costs.

[0044] The "front" here refers to the outlet close to the air outlet, and the "back" refers to one end close to the air duct.

[0045] As a component directly facing the passengers, the wind guide panel 1 is usually required to have certain aesthetics, wear resistance and light weight. Therefore, the wind guide panel 1 may be made of engineering plastics with strong weather resistance, such as ABS (acrylonitrile-butadiene-styrene copolymer) or PC (polycarbonate). ABS plastic is widely used in automotive interior parts due to its good impact resistance, molding processability and cost-effectiveness; PC is known for its high transparency, high strength and toughness, and is suitable for parts that require light transmission or high impact resistance.

[0046] The air outlet front housing 2 needs to consider the installation of the motor and provide structural support. Therefore, a stronger material may be selected, such as reinforced engineering plastics (such as glass fiber reinforced PA, i.e. nylon) or lightweight metals (such as aluminum alloy). These materials can not only provide sufficient strength to fix the motor and other accessories, but also maintain lightweight, which is beneficial to the fuel economy or battery life of the vehicle.

[0047] As a component hidden inside the dashboard, the material selection of the air outlet rear housing 7 focuses more on functionality, such as sealing, heat resistance and assembly convenience. Therefore, plastics with good heat resistance, such as PPS (polyphenylene sulfide) or PBT (polybutylene terephthalate), may be used. These materials are stable in high temperature environments and are suitable for contact with air conditioning systems. In addition, lightweight metal materials may also be used, especially if the rear housing needs to withstand certain mechanical loads or is part of the air duct.

[0048] The air guiding outer cover 3 is connected to the air guiding inner cover 5 to form an inner shell.

[0049] The front side of the air guide cover 3 is designed with an air guide slope. Specifically, the air guide cover 3 includes an upper wall plate and a lower wall plate, and a connecting plate connecting the upper wall plate and the lower wall plate; the upper wall plate and the lower wall plate are arranged as an air guide slope wall plate 8, so that the transverse cross-sectional view of the air guide cover 3 is a trapezoid with a small front and a large rear. The angle between the air guide slope wall plate 8 and the horizontal direction is 32 to 33°. This design aims to optimize the direction of the airflow and ensure that the wind direction adjustment is more in line with the comfort requirements of the human body. The rear side of the air guide cover 3 may be provided with a sheet-like limiting rib for assembling the guide slope, which is used to precisely dock with the air guide panel 1 or other interior parts, reduce the assembly gap, and improve the overall aesthetics and sealing.

[0050] The front end of the air guide outer cover 3 is connected to the decorative plate. A clamping portion is provided at the rear side of the air guide outer cover 3. A clamping portion adapted to the clamping portion is provided at the front side of the air guide inner cover 5. The connection between the air guide outer cover 3 and the air guide inner cover 5 is achieved through the adaptive clamping of the clamping portion and the clamping portion.

[0051] The air guide inner cover 5 is arranged in an arc shape with the middle part protruding toward the air outlet rear housing 7. The transverse cross-sectional view of the middle part of the air guide inner cover 5 is C-shaped. This design enables it to effectively separate the internal space of the air outlet into two independent upper and lower air ducts, providing the necessary space support for the movement of the two sets of upper blades. This special structure of the inner cover helps to guide and adjust the airflow, making it output more smoothly and evenly.

[0052] The inner shell is arranged in the outer shell cover, so that an upper blade installation cavity is formed between the upper and lower parts of the inner shell and the outer shell cover, and the inner shell is restricted in a fixed position by the upper blade retaining frame.

[0053] When selecting the materials of the air guide outer cover 3 and the air guide inner cover 5, the following factors are considered:

[0054] Temperature resistance: Must be able to withstand the range of temperatures likely to be encountered inside a vehicle, including cold air from the air conditioning system and heat from the engine compartment.

[0055] Durability: The material needs to be strong and durable enough to handle the mechanical stresses and environmental factors of long-term use.

[0056] Processability: Easy to process and shape to facilitate mass production and reduce costs.

[0057] Cost-effectiveness: Balance performance and cost and choose cost-effective materials.

[0058] Environmental protection: In the current automotive industry, the recyclability and environmental protection properties of materials are also increasingly valued.

[0059] The final material selection will be determined based on the specific requirements of the product, cost budget and market positioning.

[0060] The upper blade electric assembly 4 includes the following components;

[0061] Upper blades: This is a key component directly involved in air volume regulation. The upper blades are divided into two groups, namely the first group of upper blades and the second group of upper blades. Each group is designed with multiple blades (such as upper blades 1-5), which are usually made of lightweight and high-strength materials, such as plastic or metal alloy, and installed inside the wind guide inner cover 5. The first group of upper blades is arranged between the top of the inner shell and the outer shell, and the second group of upper blades is arranged between the bottom of the inner shell and the outer shell.

[0062] Upper blade connecting rods: There are two. Each upper blade connecting rod is used to connect multiple upper blades in each group. The mechanical linkage mechanism ensures that multiple blades in each group move synchronously. The connecting rods are usually designed with appropriate length and strength to ensure smooth and precise movement.

[0063] Upper blade holders: two. Each upper blade holder is used to fix multiple upper blades and upper blade connecting rods in each group to ensure their stable operation on a predetermined path. The upper blade holder is usually connected to the air outlet front housing 2 by screws or other fixing elements.

[0064] Stepper motor: responsible for driving the upper blades to rotate, realize the rotation of the blades and the opening and closing of the damper. The stepper motor is installed on the upper, lower or left or right side of the front housing 2 of the air outlet and fixed by screws. The PIN pin design of the motor is along the screw installation direction to prevent compression of the wires during assembly.

[0065] The lower blade electric assembly 6 includes:

[0066] Lower blades: usually made of lightweight, high-strength materials (such as plastic or alloy), designed as rotatable blades, directly involved in the fine adjustment of air volume. They are horizontally arranged sheet plates, and their shape is determined according to design requirements to achieve the ideal airflow guidance effect.

[0067] Stepper motor: As a power source, it drives the lower blades to rotate by precisely controlling the current pulses to adjust the air volume. The stepper motor is connected to the rear housing 7 of the air outlet through a preset mounting hole or fixed point, usually using screws, buckles or quick-release mechanisms to ensure that the components are firmly installed and easy to maintain.

[0068] In one embodiment, a blade buffer sponge 9 is further included; the blade buffer sponge 9 is arranged on the inner surface of the housing 7 behind the air outlet.

[0069] The blade buffer sponge 9 is usually made of soft materials with good elasticity and buffering properties, such as polyurethane sponge, EVA (ethylene-vinyl acetate copolymer) sponge or other polymer foaming materials. These materials not only have good sound absorption and shock absorption effects, but also are soft in texture, not easy to age, and can maintain stable performance in a wide temperature range.

[0070] The blade buffer sponge 9 is cut into a corresponding shape according to the specific structural design of the air outlet rear housing 7 and fixedly arranged on the inner surface of the air outlet rear housing 7. Its position precisely corresponds to the area that the lower blade may contact when it is in the extreme position, so as to achieve the best buffering effect.

[0071] When the lower blades are opened or closed to the extreme position, they may slightly collide with the rear shell 7 of the air outlet, generating unnecessary noise. The presence of the blade buffer sponge 9 can absorb this part of the impact energy, significantly reduce or eliminate the impact sound, and improve the quietness in the car. Long-term mechanical impact may cause wear or even damage to the blades or shell. The buffer sponge acts as a protective pad to reduce direct hard contact and extend the service life of the components. By reducing noise during operation, the vehicle's air conditioning system can operate more smoothly and quietly, creating a more comfortable riding environment for users.

The two air guide outer covers 3 in the two electric air outlet mechanisms are the same, and the air guide inner covers 5 are also the same.
