Description

Technical Field

[0001] This invention relates to the field of vehicle air vents, specifically to an external vehicle air vent telescopic drive structure and a telescopic air vent assembly. Background Technology

[0002] The air conditioning vents in a car are one of the key components for regulating the comfort of the cabin environment. Their core function is to direct the processed airflow to the areas needed by passengers.

[0003] Currently, the air vent designs used in the vast majority of car models on the market have relatively mature and fixed basic structures and working principles.

[0004] Traditional air vents typically consist of a fixed outer frame and an embedded air guide component (such as a blade assembly or grille). Their primary adjustment function focuses on airflow direction control; users can change the direction of the airflow in two dimensions—up and down (pitch) and left and right (yaw)—by moving or rotating the blades inside the vent. This adjustment usually relies on a ball-and-socket joint mechanism or similar universal joint structure to achieve multi-angle positioning. However, the adjustment dimension of such designs is limited to the angle of the airflow, and there is absolutely no active adjustment for the physical distance between the air outlet and the passenger's face or body.

[0005] The air vents are permanently fixed to a specific mounting location on the dashboard or interior panel, and their airflow distance (i.e., the straight-line distance from the air vent grille to the passenger) is constant.

[0006] This fixed airflow distance design has revealed obvious flaws and limitations in practical use. First, it cannot meet the personalized and diverse comfort needs of passengers.

[0007] Passengers often need to adjust the airflow distance for personal comfort during use. However, most car air vents on the market currently lack this feature, resulting in a limited user experience. For example, in hot summers, some passengers may prefer a close, direct airflow for rapid cooling; while in milder temperatures or when passengers are more sensitive, a gentler, more dispersed airflow from a greater distance is needed to avoid the discomfort of direct cold air. Existing designs cannot accommodate this, leading to a limited and passive user experience.

[0008] The prior art CN119175989A discloses a retractable multi-functional air vent and an automobile; however, it only discloses the shell structure of the air vent, but lacks a drive unit.

[0009] CN210941281U provides a retractable automotive air conditioning vent and an automobile, belonging to the field of vehicle air conditioning system components. The retractable automotive air conditioning vent includes an air conditioning vent body, with an air conditioning vent adjustment panel at the front end and a retractable corrugated pipe at the rear end; the retractable corrugated pipe is located inside the dashboard. However, this prior art does not possess any functions other than air venting.

[0010] Therefore, in order to improve or solve at least one of the above technical problems, it is necessary to optimize the design of the existing air outlet structure. Summary of the Invention

[0019] The outer shell includes a base shell and a pedestal shell; the pedestal shell and the base shell are connected by a detachable connection; the inner shell is connected to the base shell through the pedestal shell.

[0020] The base shell includes a connecting seat and a connecting plate, the connecting plate being connected to the base shell via the connecting seat; the inner shell is connected to the connecting plate via a guide unit, the guide unit including a sliding groove disposed on the connecting plate and a sliding block disposed on the inner shell body.

[0021] The inner shell includes an inner shell body, and a latch is provided at the end of the inner shell body; the inner shell body is provided with a sliding block and an assembly groove.

[0022] A damping unit is provided between the outer shell and the inner shell. The damping unit includes a gear damper provided on the outer shell and a rack provided on the inner shell.

[0023] The base shell includes a bottom plate; the bottom plate has lateral connecting plates on opposite sides; the bottom plate has at least two fixing holes;

[0024] The base plate includes a middle base plate, and both ends of the middle base plate are connected to side connecting plates via a bottom connecting plate; the middle base plate and the bottom connecting plate are staggered; the middle base plate is connected to the bottom connecting plate via an arc connecting plate.

[0025] A telescopic air vent assembly includes an outer air vent housing and an inner air vent housing; the inner air vent housing is inserted into the end of the outer air vent housing; the inner air vent housing is connected to the outer air vent housing via an external vehicle air vent telescopic drive structure.

[0026] The outer air vent housing is provided with an air outlet channel, which includes a first channel and a second channel; the first channel and the second channel are connected; the inner air vent housing is inserted into the second channel; the vertical cross-sectional area of ​​the first channel is greater than the vertical cross-sectional area of ​​the second channel; in the external vehicle air vent telescopic drive structure, the outer shell is connected to the outer air vent housing, and the inner shell is connected to the inner air vent housing.

[0027] The advantages of this invention are:

[0028] This invention discloses an external vehicle air vent telescopic drive structure and a telescopic air vent assembly.

[0029] Flexible airflow distance adjustment: Through the relative sliding structure between the inner and outer shells, combined with the drive and locking mechanisms, the overall position of the air outlet can be moved smoothly and controllably forward and backward. Users can freely adjust the airflow distance between the air outlet and the passenger according to their own needs, meeting personalized air supply needs based on different temperatures, comfort preferences, and health conditions.

[0030] Enhanced comfort and health: This design avoids the discomfort such as headaches and colds caused by prolonged direct airflow onto the head or body, which can result from the fixed airflow distance of traditional air vents. Users can move the air vent further away or closer to the head to obtain a gentler, more dispersed airflow, improving riding comfort and reducing health risks.

[0031] Stable and reliable structure: The self-locking structure (lock and latch cooperation) ensures reliable fixation of the inner shell, guaranteeing stable locking at any extension or retraction position and preventing displacement due to vibration during operation. The slide rail and guide unit (sliding groove and sliding block) ensure smooth, jam-free movement and extend service life.

[0032] Convenient driving and resetting: The drive mechanism uses a drive spring to provide extension and retraction power. Its simple structure and sensitive response allow for one-button or touch-based operation. The combination of the spring and drive sleeve provides thrust as well as assists in guidance and resetting, making adjustments easy and effortless for users.

[0033] Highly modular and maintainable: The outer shell features a detachable base shell and pedestal shell design, facilitating assembly, repair, or replacement of internal components. The inner shell and drive mechanism are modularly integrated, which is beneficial for production line assembly and subsequent maintenance.

[0034] Highly adaptable and easy to integrate: This structure can be used as an independent drive module (external automotive air vent telescopic drive structure) in various air vent assemblies. By connecting with the outer air vent housing and the inner air vent housing, it can quickly upgrade and transform traditional air vents without changing the main body of the original air duct system.

[0035] Damping and buffering enhance the feel: Optional gear dampers and rack and pinion structures provide a smooth damping feel during the extension and retraction process, resulting in a better operating feel, preventing rapid bounce, and improving product quality and user experience.

[0036] Optimized airflow organization: When the inner air vent housing extends into the outer air vent housing, the flatness of the air outlet cavity can be ensured. Attached Figure Description

[0046] 1-1 Telescopic drive structure; 1-2 Inner air vent housing; 1-3 Outer air vent housing. Detailed Implementation

[0047] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0048] An external vehicle air vent telescopic drive structure includes a housing, on which a locking mechanism and a drive mechanism are provided. The housing includes an outer shell 1 and an inner shell 2, the inner shell 2 being movable relative to the outer shell 1. The locking mechanism is used to lock and fix the outer shell 1 and the inner shell 2. The drive mechanism is used to push the inner shell 2 to move within the outer shell 1. The external vehicle air vent telescopic drive structure 1-1 disclosed in this invention is mainly applicable to telescopic air vents. The external vehicle air vent telescopic drive structure 1-1 disclosed in this invention mainly includes a housing, which is the main structure of the external vehicle air vent telescopic drive structure 1-1. The housing is provided with a locking mechanism and a drive mechanism. The locking mechanism is used to lock and fix the outer shell 1 and the inner shell 2, while the drive mechanism is mainly used to enable the inner shell 2 to move autonomously relative to the outer shell 1 after the outer shell 1 and the inner shell 2 are unlocked.

[0049] In this invention, the drive mechanism (specifically the drive spring 3) is the power source for the telescopic movement. When the user unlocks the device, the preload or release force of the spring automatically pushes the inner housing 2 outward. When the user needs to retract the device, the spring can be compressed to store energy for the next extension.

[0050] It enables "one-click" or "touch" operation. Users only need to unlock the door and the air outlet will automatically extend. The operation is intuitive and effortless, enhancing the convenience and premium feel of the product.

[0051] The locking mechanism (the engagement of latch 4 and bolt 41) is crucial for maintaining the position. When the inner housing 2 moves to a preset position (or achieves any position through a continuous mechanism), bolt 41 engages with latch 4, rigidly locking the inner housing 2 to the outer housing 1.

[0052] It ensures that the air outlet position will not accidentally slide or retract under the vibration environment of vehicle driving, and the air blowing direction and distance can be kept stable to meet the user's personalized setting needs.

[0053] The entire structure relies on the precise fitting of the outer shell 1 and the inner shell 2, as well as any guide units (such as the sliding block 24 and the sliding groove 13). This enhances the linear guidance of the telescopic movement.

[0054] Initial (retracted) state: The inner housing 2 is housed inside the outer housing 1, the drive spring 3 is in a compressed or pre-tightened state, and the locking mechanism is locked.

[0055] Extension process: The user operates the unlocking device (such as pressing the component linked to the latch 4) to disengage the latch 4 from the bolt 41.

[0056] Once the lock is released, the elastic force of the drive spring 3 is released, pushing the inner housing 2 to slide smoothly outward along the slide rail or guide groove.

[0057] Recovery process:

[0058] The user pushes the inner shell 2 back by hand. At this time, the external force overcomes the force of the drive spring 3 and compresses it.

[0059] When pushed to the retracted locking position, the locking mechanism locks the outer shell 1 and the inner shell 2 again.

[0060] Furthermore, in this invention, the locking mechanism includes a latch 4 disposed on the outer shell 1 and a latch 41 disposed on the inner shell 2; the driving mechanism includes at least one driving component, the driving component including a driving spring 3, one end of the driving spring 3 being connected to the outer shell 1 and the other end being connected to the inner shell 2; the driving component also includes a driving sleeve 31, the driving sleeve 31 being inserted into the driving spring 3 and connected to the outer shell 1; the core of the locking mechanism is the pairing combination of the latch 4 and the latch 41, and its working principle is similar to that of a push-button cabinet door.

[0061] The latch 4 is fixed to the outer casing 1. It serves as the fixing or receiving end of the locking system. Its function is to provide a fixed locking position for "grabbing" or "locking" the latch 41 from the inner casing 2. It determines the specific locking position of the inner casing 2.

[0062] A latch 41 is disposed on the inner housing 2. It serves as the moving or triggering end of the locking system. It is typically a latch component. When the inner housing 2 moves, the latch 41 moves accordingly; when it reaches the locked position, the latch 41 engages with the latch 4 on the outer housing 1, thereby preventing the inner housing 2 from moving further. This achieves a rigid connection between the moving and fixed components and is the component that directly performs the locking action.

[0063] The core of the drive mechanism is the combination of the drive spring 3 and the drive sleeve 31, which is responsible for converting the stored elastic potential energy into smooth linear motion.

[0064] One end of the drive spring 3 is connected to the outer shell 1, and the other end is connected to the inner shell 2. The connection method can be contact pressing or fixed connection. The specific connection method can be selected according to the needs. Generally, for the convenience of assembly, disassembly and replacement, the two ends of the drive spring 3 are required to press against the inner shell 2 and the outer shell 1 respectively.

[0065] In this invention, the drive spring 3 primarily stores energy and provides power: when the inner housing 2 is pushed back, the spring is compressed, storing elastic potential energy. When the lock is released, the spring releases energy, generating a driving force that pushes the inner housing 2 outward.

[0066] As the user manually pushes the air vent back, the spring force gradually increases, providing a certain degree of damping and clear feedback at the end of the stroke. This automates the telescopic movement (one-button pop-out) and provides elastic assistance, greatly improving the user experience and serving as the energy source for the driving function.

[0067] The drive sleeve 31 is inserted into the drive spring 3 and connected to the outer casing 1; generally, a fixed connection is used here. The drive sleeve 31 mainly serves as a limiting and restraining function, providing radial support force to the drive spring 3 to ensure its smooth operation and prevent excessive bending of the drive spring 3 due to gravity or other reasons, which would affect its operation within the settling groove 26. In other words, it prevents the drive spring 3 from lateral bending, twisting, or buckling (instability) when under force.

[0068] Meanwhile, the drive sleeve 31 also serves as a limiter. By limiting its length, the depth to which the inner housing 2 is inserted into the outer housing 1 can be restricted, as can the maximum deformation of the drive spring 3, preventing it from being over-compressed and damaged, and reducing friction between the spring coils.

[0069] In this invention, the driving component also includes a recessed groove 26 disposed on the inner housing 2; one end of the driving spring 3 is inserted into the recessed groove 26; in this invention, the recessed groove 26 is essentially a cylindrical groove structure, mainly used to arrange the driving spring 3; the position of one end of the driving spring 3 is defined; in this invention, the inner diameter of the recessed groove 26 is larger than the outer diameter of the driving sleeve 31, which can reduce the installation and movement interference between components.

[0070] In this invention, a typical driving mechanism includes two driving components, which are distributed symmetrically at intervals.

[0071] In this invention, a recess 26 is arranged on the inner housing 2, and near the locking end 4, it is a groove or cavity for accommodating the end of the drive spring 3. During movement, this prevents the end of the drive spring 3 from slipping off the connection point. This allows the drive spring 3 to be partially embedded inside the inner housing 2, improving the reliability and integrity of the drive mechanism connection, reflecting a refined design.

[0072] Operation procedure: User unlocks (latch 41 disengages from latch 4) → Drive spring 3 releases, pushing the inner housing 2 to extend smoothly along the outer housing 1.

[0073] In this invention, the outer shell 1 includes a base shell 11 and a base shell 12; the base shell 12 and the base shell 11 are connected by a detachable connection; the inner shell 2 is connected to the base shell 11 through the base shell 12; the present invention, through the arrangement of the base shell 11 and the base shell 12, makes the outer shell 1 a box structure with an opening at least at one end, which facilitates the subsequent insertion and installation of the inner shell 2.

[0074] In this invention, the base shell 11 is fixed on the outer wall of the outer air vent shell, and the base shell 12 acts as a connector, which facilitates the connection between the inner shell 2 and the outer shell 1. At the same time, the driving mechanism, the guiding unit and the locking mechanism of this invention are all arranged on the base shell 12, so that the base shell 12 acts as a connection base, which facilitates subsequent integration and assembly.

[0075] In this invention, the base shell 11 is the main part that fixes the outer shell 1 to the outer air outlet shell. Through the fixing holes on it, screws or other fasteners are used to securely install the entire air outlet drive structure at a predetermined position on the outer air outlet shell, providing the main rigidity and support for the outer shell 1.

[0076] The base shell 12 serves as the "functional load-bearing cover" of the outer shell 1 and as a direct guide and support for the inner shell 2. Typically, functional components requiring precise positioning, such as the latch 4, the fixed end of the drive sleeve 31, and the gear damper 5, are directly mounted on the connecting plate 122 of the base shell 12.

[0077] Guide unit mounting surface: The sliding groove 13 on it (as part of the guide unit) is a precise track for guiding the inner housing 2 to slide, which determines the smoothness of the telescopic movement.

[0078] After the base shell 12 and the base shell 11 are combined, they together form a complete and closed cavity that encloses the motion mechanism.

[0079] The base shell 12 and the base shell 11 of the present invention are connected by a detachable connection method; the detachable connection method (such as buckles, screws) is mainly to achieve non-permanent fixation between the base shell 11 and the base shell 12. This design facilitates assembly: it allows all internal mechanisms (springs, inner shell 2, latch 41, etc.) to be installed on the base shell 12 as a sub-module during production line or maintenance, and then quickly assembled with the fixed base shell 11.

[0080] When internal mechanisms (such as spring failure or gear damper 5 damage) need to be repaired or replaced, there is no need to disassemble the entire air outlet assembly or damage the installation of the base shell 11. All core components can be directly exposed simply by opening the base shell 12, which greatly reduces the difficulty and cost of maintenance.

[0081] In actual design, different stroke or gear models can be quickly derived by modifying the design of the base shell 12 (such as the length of the sliding groove 13 and the position of the latch 4), while the mounting interface of the base shell 11 can remain universal to adapt to the mounting points of different vehicle models.

[0082] In summary, the design of splitting the outer casing 1 into a base casing 11 and a base casing 12, and connecting them in a detachable manner, is a highly forward-thinking engineering design. It goes beyond simply achieving basic functionality, optimizing the entire lifecycle from the perspectives of manufacturing, after-sales service, and cost control. This results in an air vent drive structure that not only boasts superior performance but also excellent adaptability to industrial production and user-friendly maintainability. This is typically a key characteristic of high-end or mature automotive components.

[0083] Furthermore, in this invention, the base shell 12 includes a connecting seat 121 and a connecting plate 122. The connecting plate 122 is connected to the base shell 11 through the connecting seat 121. In this invention, the thickness of the connecting seat 121 is greater than the thickness of the connecting plate 122. Based on this design, the base shell 12 forms an L-shaped structure. When the base shell 12 is connected to the base shell 11, the screw passes through the side of the base shell 11 and connects to the side of the connecting seat 121 on the base shell 12. At the same time, because the connecting seat 121 and the connecting plate 122 have different thicknesses, the drive sleeve 31 can be arranged on the end face of the connecting seat 121 during subsequent use, which facilitates the suspended arrangement of the drive sleeve 31 inside the outer shell 1.

[0084] In this invention, the inner shell 2 is connected to the connecting plate 122 via a guide unit. The guide unit includes a sliding groove 13 disposed on the connecting plate 122 and a sliding block 24 disposed on the inner shell body 21. The guide unit ensures the linearity of the relative movement between the inner shell 2 and the outer shell 1.

[0085] In this invention, the sliding block 24 can be attached to the outer shell 1. Based on the actual design, the sliding groove 13 and the sliding block 24 can be designed as a T-shaped structure with a vertical cross-section. In this invention, the sliding groove 13 includes a guide section and an assembly section. The guide section of the sliding groove 13 has a T-shaped vertical cross-section, and the assembly section has a U-shaped vertical cross-section. Essentially, the sliding groove 13 is divided into a first sliding groove 13 and a second sliding groove 13, which are connected. The first sliding groove 13 is T-shaped, and the second sliding groove 13 is U-shaped. The second sliding groove 13 is located at the end of the outer shell 1 away from the latch 4. The length of the first sliding groove 13 is not less than the running length of the inner shell 2 within the outer shell 1. Based on the above design, the end of the inner shell 2 away from the inner air vent shell can be attached to the outer air vent shell, ensuring that both ends of the inner shell 2 have support points, reducing the stress at the connection between the inner shell 2 and the air vent shell.

[0086] Meanwhile, the second sliding groove 13 of the assembly section plays a good role in avoiding obstacles, making it convenient for the sliding block 24 on the inner shell 2 to pass through the outer shell 1, and making it convenient for the sliding block 24 to be hung on the sliding groove 13.

[0087] In this invention, the inner shell 2 includes an inner shell body 21, and a latch 41 is provided at the end of the inner shell body 21. The inner shell body 21 is provided with a sliding block 24 and an assembly groove 22. The inner shell body 2 is the main structure of the inner shell 2, and the lock door is located at the end of the inner shell body 21. The sliding block 24 is provided on the inner shell body 21. The sliding block 24 and the inner shell body 21 are generally designed as an integral structure, but it can also be an external structure, which can be selected according to needs. One function of the assembly groove 22 is to act as a material reduction groove. In addition, there are holes in the assembly groove 22. The subsequent fasteners pass through the holes in the assembly groove 22 and connect to the air outlet inner shell. The assembly groove 22 can accommodate the corresponding fasteners and prevent the fasteners from being exposed on the outside of the shell.

[0088] Furthermore, in this invention, a damping unit is provided between the outer shell 1 and the inner shell 2. The damping unit includes a gear damper 5 mounted on the outer shell 1 and a rack 23 mounted on the inner shell 21. The gear damper 5 is fixed to the outer shell 1 (typically the base shell 12). It is a small device, with its core being a gear system that generates rotational resistance through viscous silicone oil or other media. A small gear on its output shaft is exposed. The rack 23 is fixed to the inner shell 2 and parallel to the direction of movement of the inner shell 2. The rack 23 is essentially a toothed straight rod.

[0089] The pinion gear on the gear damper 5 meshes with the rack 23 on the inner housing 2. When the inner housing 2 extends or retracts within the outer housing 1, it drives the rack 23 to move linearly. The linear motion of the rack 23 forces the pinion gear of the gear damper 5 to rotate. As the pinion gear rotates, it needs to overcome the resistance generated by the viscous medium inside the damper. This resistance, through the meshing of the gear and rack 23, is converted into a smooth and continuous damping force that opposes the linear motion of the inner housing 2. This provides excellent handling and a premium feel.

[0090] After the user unlocks the device, the thrust of the drive spring 3 is balanced by the damping force, making the extension and retraction of the inner housing 2 slow, uniform, and smooth, rather than a rapid pop-out. The damping force effectively buffers the instantaneous impact of spring release and protects the delicate locking mechanism (latch 4 / latch 41) and guide unit from sudden external forces that may be applied during manual operation, preventing them from wearing, deforming, or failing due to impact, thus extending the service life of the entire mechanism. When the vehicle is traveling on bumps, the damping force effectively suppresses accidental sliding or shaking of the inner housing 2 caused by vibration, and even if there is a slight gap in the locking mechanism, no unpleasant noise will be produced. This ensures the stability of the air vent position under various operating conditions, improving safety and passenger comfort.

[0091] Furthermore, in this invention, the base shell 11 includes a bottom plate 111; the bottom plate 111 is provided with lateral connecting plates 112 on opposite sides; based on this, the base shell 11 is in the form of a U-shaped structure, and the bottom plate 111 is provided with at least two fixing holes; generally, three fixing holes are provided, and the three fixing holes are distributed in an equilateral triangle, through which fasteners are connected to the outer air vent shell.

[0092] In this invention, the base plate 111 includes a middle base plate 101, and the two ends of the middle base plate 101 are respectively connected to the side connecting plates 112 through a bottom connecting plate 103; the middle base plate 101 and the bottom connecting plate 103 are staggered; the middle base plate 101 is connected to the bottom connecting plate 103 through an arc connecting plate 102; based on this design, the middle part of the base plate 111 has a concave structure, which facilitates avoiding the protrusions on the outer air vent housing. At the same time, a groove structure can be provided at the lower end of the base plate 111. In subsequent use, the base plate 111 is fitted onto the protrusions of the outer air vent housing through the groove, realizing the self-positioning of the base shell 11 and the outer air vent housing; ensuring the stability and accuracy of the connection between the outer air vent housing and the external vehicle air vent telescopic drive structure 1-1.

[0093] A telescopic air outlet assembly includes an outer air outlet housing 1-3 and an inner air outlet housing 1-2. The inner air outlet housing 1-2 is inserted into the end of the outer air outlet housing 1-3. The inner air outlet housing 1-2 is connected to the outer air outlet housing 1-3 through an external vehicle air outlet telescopic drive structure 1-1. This invention discloses a telescopic air outlet assembly. Through the relative sliding structure between the inner housing 2 and the outer housing 1, combined with a drive mechanism and a locking mechanism, the overall position of the air outlet can be moved smoothly and controllably forward and backward. Users can freely adjust the airflow distance between the air outlet and the passenger according to their own needs, meeting the personalized air supply needs of different temperatures, body preferences, and health conditions.

[0094] Enhanced comfort and health: This design avoids the discomfort such as headaches and colds caused by prolonged direct airflow onto the head or body, which can result from the fixed airflow distance of traditional air vents. Users can move the air vent further away or closer to the head to obtain a gentler, more dispersed airflow, improving riding comfort and reducing health risks.

[0095] In addition, the outer air vent housing 1-3 of the present invention is provided with an air outlet channel, which includes a first channel and a second channel; the first channel and the second channel are connected; the inner air vent housing 1-2 is inserted into the second channel; the outer shell 1 of the external vehicle air vent telescopic drive structure 1-1 is connected to the outer air vent housing 1-3, and the inner shell 2 of the external vehicle air vent telescopic drive structure 1-1 is connected to the inner air vent housing 1-2; based on this arrangement, the movement of the inner shell 2 of the external vehicle air vent telescopic drive structure 1-1 relative to the outer shell 1 can be converted into the movement of the inner air vent housing 1-2 relative to the outer air vent housing 1-3.

[0096] Furthermore, in this invention, the vertical cross-sectional area of ​​the first channel is greater than that of the second channel. This arrangement creates a stepped platform at the connection between the first and second channels. This platform can limit the retraction position of the inner air vent housing 1-2. At the same time, by controlling the wall thickness of the inner air vent housing 1-2 relative to the outer air vent housing 1-3, and in conjunction with the above design, the flatness of the inner sidewall of the inner air vent housing 1-2 relative to the inner sidewall of the outer air vent housing 1-3 can be guaranteed.

[0097] In this invention, the outer air vent housing 1-3 is the outer frame and air duct of the air outlet assembly.

[0098] It has an internal air outlet duct; the inner air vent housing 1-2: the movable part that actually delivers the airflow, usually with a grille and air direction deflector. It faces the passengers directly.

[0099] Special design of the air outlet duct: First duct: located at the rear end inside the outer air outlet housing 1-3, with a larger cross-sectional area. Second duct: located at the front end inside the outer air outlet housing 1-3, with a smaller cross-sectional area; the inner air outlet housing 1-2 is normally inserted into it. Design intention: This "large cavity connecting to a small tube" design is crucial. The large space of the first duct is conducive to collecting the incoming airflow from the air conditioning duct and stabilizing the airflow; the contraction of the second duct guides and accelerates the airflow and serves as a precision guide tube for the extension and retraction movement of the inner air outlet housing 1-2.

[0100] The outer shell 1 of the external vehicle air vent telescopic drive structure 1-1 is fixedly connected to the outer air vent housing 1-3. The inner shell 2 of the drive structure is fixedly connected to the inner air vent housing 1-2.

[0101] The relative linear motion between the inner and outer shells 1 of the drive structure is transmitted 1:1 to the inner and outer air outlet shells 1-3 of the air outlet. When the drive structure is working, the inner air outlet shell 1-2 extends or retracts precisely accordingly.

[0102] Initial (retracted) state: The inner air vent housing 1-2 is mostly housed in the second channel, with a compact appearance.

[0103] The spring in the drive mechanism is compressed, and the locking mechanism is locked.

[0104] Extension process: User unlocks. Drive spring 3 is released, pushing the inner housing 2 of the drive structure outward. Since the inner housing 2 is rigidly connected to the inner air vent housing 1-2, the inner air vent housing 1-2 slides smoothly out of the second channel, increasing the distance between the air vent grille and the passenger.

[0105] The damping unit ensures a smooth, uniform, and quiet sliding process.

[0106] When the inner air vent housing 1-2 extends, the airflow enters the second channel (small) from the first channel (large), producing a slight "Venturi effect" or simple cross-sectional contraction acceleration, which helps to maintain or even slightly increase the outlet air velocity and compensate for the weakening of the airflow due to the increased distance between the air vents.

[0107] At the same time, this design can reduce turbulence and wind noise caused by the movement of the inner air vent housing 1-2, ensuring that the airflow is relatively stable in different extension and retraction positions.

[0108] The user reverses the operation, and the inner air vent housing 1-2 retracts smoothly with the assistance of the drive mechanism, restoring its initial compact state.

[0109] Based on the above design, the retractable drive structure 1-1 for vehicle air vents seamlessly integrates mechanical telescopic motion with air conditioning function.

[0110] The retractable drive structure 1-1 for vehicle air vents of this invention can serve as a standardized "power compartment" and can be adapted to external air vent housings 1-3 with different shapes and air volumes, greatly simplifying the vehicle adaptation and upgrade process.

[0111] Regardless of the shape of the air vent, the user experience (smooth damping, one-button pop-up, precise locking) obtained through this retractable automotive air vent drive structure 1-1 is consistent and of high quality, enhancing the overall brand image.

[0112] If the drive module needs repair, it can be removed from the assembly relatively independently without replacing the entire air outlet panel, reducing after-sales costs.

[0113] The retractable drive structure 1-1 for automotive air vents disclosed in this invention can be easily externally connected to existing "air vent assemblies" (outer air vent housing 1-3, inner air vent housing 1-2). This greatly simplifies the product upgrade and modification process, eliminating the need to redesign the entire air conditioning duct system.

[0114] The "telescopic drive" function is separated from functions such as "airflow direction adjustment" and "airflow / damper control," each handled by a dedicated structure. This division of labor makes the mechanical structure of each function more specialized, more reliable, and prevents interference between them.

[0115] With its compact structure, the inner shell 2 is completely hidden within the outer shell 1 when retracted, without occupying additional dashboard space; when extended, it makes full use of the space in front of the original air vent. It fundamentally solves the pain point of the fixed air blowing distance of traditional air vents, giving users control over the distance dimension of the air conditioning airflow, which is a major leap in comfort.

[0116] In summary, this "External Vehicle Air Vent Telescopic Drive Structure 1-1" is a sophisticated mechatronic module. Through the efficient coordination of the spring (providing power), the slide rail / sleeve rod (guiding direction), and the latch 4 / latch 41 (fixing position), it makes a simple linear telescopic movement controllable, reliable, smooth, and user-friendly.

[0117] Example 1:

[0118] The external vehicle air vent telescopic drive structure 1-1 disclosed in this invention is mainly applicable to telescopic air vent assemblies.

[0119] The telescopic air outlet assembly disclosed in this invention utilizes the synergistic effect of the drive mechanism, locking mechanism, and guide unit to ensure that the air outlet housing can achieve the telescopic function of extending and retracting in a stable state.

[0120] The telescopic function is implemented as follows: When the user presses the inner air vent housing 1-2, the inner air vent housing 1-2 will drive the inner housing 2 to trigger the numbered PUSH lock switch, and the inner housing 2 will be unlocked from the PUSH lock.

[0121] Under the combined action of the drive spring 3 and the spring sleeve rod, the inner housing 2 moves along a predetermined trajectory. The inner housing 2 is tightly connected to the inner air vent housing 1-2 by screws. As the inner housing 2 extends, the inner air vent housing 1-2 also extends, thus realizing the extension function of the air vent.

[0122] Conversely, when the user presses the surface of the air vent panel, the inner housing 2 moves along a predetermined trajectory. The inner housing 2 is connected to the inner air vent housing 1-2 by screws. As the inner housing 2 retracts, the PUSH lock automatically locks with the inner housing 2, thus allowing the inner air vent housing 1-2 to retract smoothly, achieving the air vent retraction function.

[0123] Example 2:

[0124] This invention discloses an external vehicle air vent telescopic drive structure 1-1 and a telescopic air vent assembly including the structure.

[0125] External vehicle air vent telescopic drive structure 1-1:

[0126] The external vehicle air vent telescopic drive structure 1-1 mainly includes a housing, a locking mechanism, and a drive mechanism.

[0127] The housing includes an outer shell 1 and an inner shell 2. The inner shell 2 is capable of linear motion relative to the outer shell 1.

[0128] The locking mechanism is used to lock and fix the outer shell 1 and the inner shell 2 in different relative positions. The locking mechanism includes a latch 4 disposed on the outer shell 1 and a latch 41 disposed at the end of the inner shell 2. The latch 4 serves as a fixed receiving end, and the latch 41 serves as a movable trigger end. The two work together to achieve reliable engagement and disengagement, thereby rigidly locking the inner shell 2 onto the outer shell 1 or unlocking it.

[0129] The drive mechanism provides a driving force to move the inner housing 2 relative to the outer housing 1 after the inner housing 2 is unlocked. The drive mechanism includes at least one drive component. Each drive component includes a drive spring 3 and a drive sleeve 31. One end of the drive spring 3 is connected to the outer housing 1, and the other end is connected to the inner housing 2; the connection can be either compression or fixation. When the inner housing 2 is pushed back, the drive spring 3 is compressed to store elastic potential energy; when the lock is released, this elastic potential energy is released and converted into a force that pushes the inner housing 2 outward. The drive sleeve 31 is fixedly connected to the outer housing 1 and inserted inside the drive spring 3, serving as a core guide component. Its function is to provide radial support for the drive spring 3, preventing the spring from bending, twisting, or becoming unstable during compression or extension, and simultaneously limiting the maximum stroke of the inner housing 2 and the maximum compression of the spring through its own length, thus playing a mechanical limiting role.

[0130] Furthermore, to optimize assembly and connection, the drive component also includes a recessed groove 26 disposed on the inner housing 2. The end of the drive spring 3 is inserted into the recessed groove 26 to achieve stable positioning and containment, preventing the spring from dislodging. The inner diameter of the recessed groove 26 is larger than the outer diameter of the drive sleeve 31 to avoid motion interference. Typically, the drive mechanism may include two relatively symmetrically spaced drive components to provide balanced driving force.

[0131] The outer shell 1 adopts a split modular design, including a base shell 11 and a base shell 12, which are connected by a detachable connection method (such as clips or screws). The inner shell 2 is indirectly connected to the base shell 11 through the base shell 12. The base shell 11 serves as the foundation for fixing the entire drive structure to the outside (such as the external air vent shell), and it is provided with at least two fixing holes for installation using fasteners. The base shell 12 serves as a functional load-bearing unit, and precision components such as the locking buckle 4 and the fixing end of the drive sleeve 31 are all installed on the base shell 12. This design allows the base shell 12, which contains all moving parts, to be assembled, tested, and repaired as an independent sub-module, greatly improving production efficiency and maintenance convenience.

[0132] Specifically, the base shell 12 includes a connecting seat 121 and a connecting plate 122, with the connecting plate 122 connected to the base shell 11 via the connecting seat 121. The thickness of the connecting seat 121 is typically greater than the thickness of the connecting plate 122, resulting in an overall L-shaped structure for the base shell 12. This facilitates lateral connection with the base shell 11 and also provides space for the arrangement of components such as the drive sleeve 31.

[0133] To ensure the linearity and stability of the inner shell 2's movement, the inner shell 2 is connected to the connecting plate 122 of the base shell 12 via a guide unit. The guide unit includes a sliding groove 13 on the connecting plate 122 and a sliding block 24 on the inner shell 2. The cooperation between the sliding block 24 and the sliding groove 13 provides precise linear guidance. The sliding groove 13 can be designed to include a connecting guide section and an assembly section. The vertical cross-section of the guide section is T-shaped, allowing the sliding block 24 to be hooked into it for stable support; the vertical cross-section of the assembly section is U-shaped, facilitating the sliding block 24 to slide into the guide section during assembly. This design ensures effective support at both ends of the inner shell 2, improving the force distribution.

[0134] The inner housing 2 mainly includes an inner housing body 21. One end of the inner housing body 21 is provided with the latch 41 described above, and the side is provided with a sliding block 24 that cooperates with the guide unit, and a recessed groove 26 for accommodating the end of the drive spring 3 is provided. The inner housing body 21 may also be provided with an assembly recessed groove 22, which can be used to reduce weight, or to provide a connection hole for fasteners to pass through to connect external components (such as the air outlet inner housing), and to embed the head of the fastener in the groove to maintain a flat appearance.

[0135] To further enhance handling and motion quality, a damping unit is provided between the outer shell 1 and the inner shell 2. The damping unit includes a gear damper 5 fixed to the outer shell 1 (typically the base shell 12) and a rack 23 fixed to the inner shell body 21 and parallel to the direction of movement of the inner shell 2. The pinion of the gear damper 5 is constantly meshed with the rack 23. When the inner shell 2 extends or retracts, the linear motion of the rack 23 forces the pinion to rotate, thereby overcoming the viscous resistance inside the damper and generating a smooth and continuous damping force. This damping force makes the extension and retraction of the inner shell 2 slow, uniform, and smooth, eliminating harsh mechanical impact and effectively suppressing unexpected shaking or abnormal noises that may be caused by driving vibrations, thus protecting the internal mechanisms.

[0136] More specifically, the base shell 11 includes a base plate 111 and lateral connecting plates 112 located on opposite sides of the base plate 111, forming an overall U-shaped structure. The base plate 111 may further include a middle base plate 101, with both ends of the middle base plate 101 connected to the lateral connecting plates 112 via arc connecting plates 102 and bottom connecting plates 103, respectively, so that the middle base plate 101 and the bottom connecting plates 103 on both sides are staggered, forming a concave structure in the middle. This design facilitates avoidance of other components at the installation position, and a groove can be provided at the lower end of the base plate 111 to cooperate with the protrusions on the outer shell, achieving rapid self-positioning installation and ensuring connection accuracy.

[0137] Telescopic air vent assembly; based on the above-mentioned drive structure, the present invention also discloses a telescopic air vent assembly. The assembly includes an outer air vent housing 1-3, an inner air vent housing 1-2, and the aforementioned external vehicle air vent telescopic drive structure 1-1.

[0138] The inner air vent housing 1-2 is inserted into the end of the outer air vent housing 1-3. The outer housing 1 of the external vehicle air vent telescopic drive structure 1-1 is fixedly connected to the outer air vent housing 1-3, while its inner housing 2 is fixedly connected to the inner air vent housing 1-2. Thus, the linear telescopic movement of the inner housing 2 relative to the outer housing 1 is directly converted into the linear telescopic movement of the inner air vent housing 1-2 relative to the outer air vent housing 1-3, thereby achieving flexible adjustment of the blowing distance.

[0139] An air outlet channel is provided inside the outer air outlet housing 1-3, which includes a first channel and a second channel that are connected to each other. The inner air outlet housing 1-2 is inserted into the second channel when retracted. The vertical cross-sectional area of ​​the first channel is larger than that of the second channel. This variable cross-sectional design allows the first channel to collect and stabilize the airflow from the air conditioning duct, while the second channel guides and accelerates the airflow, helping to maintain the outlet air velocity when the inner air outlet housing 1-2 is extended, reducing wind loss and airflow noise. Simultaneously, the stepped platform formed at the connection between the first and second channels limits the maximum retracted position of the inner air outlet housing 1-2.

[0140] Work process and beneficial effects

[0141] In the initial state, the inner housing 2 together with the inner air vent housing 1-2 is in the retracted position, the drive spring 3 is compressed and stored energy, and the latch 41 engages with the latch 4 to lock.

[0142] When the blowing distance needs to be adjusted, the user operates the unlocking device (such as pressing the component linked to the latch 4) to disengage the latch 4 from the bolt 41. Once the lock is released, the elastic force stored in the drive spring 3 is released instantaneously, pushing the inner housing 2 and the connected inner air outlet housing 1-2 along the sliding groove 13 and the drive sleeve 31, extending smoothly and uniformly outward. The damping unit provides smooth damping force during this process, ensuring smooth and quiet movement. The user can release the unlocking device at any desired position, and the bolt 41 will re-engage with the currently corresponding latch 4 position (or through a continuous locking mechanism) under the spring force or its own elasticity, achieving rigid locking.

[0143] When the air outlet needs to be retracted, the user unlocks the device again and manually pushes the inner air outlet housing 1-2 inward. At this point, external force overcomes the elasticity of the drive spring 3 and the resistance of the damper, pushing the inner housing 2 back, and the drive spring 3 is recompressed and recharged. The locking mechanism locks again once the inner housing 2 is pushed back to its initial locked position.

[0144] This invention achieves controllable, reliable, and sophisticated air outlet extension and retraction through the efficient coordination of a locking mechanism, a drive mechanism (spring and sleeve), a guide unit, and a damping unit. Its modular design facilitates production, assembly, and maintenance, and it can be externally connected to various traditional air outlet assemblies without altering the main air duct system. Ultimately, this structure grants users the ability to independently adjust the airflow distance, effectively avoiding the discomfort caused by fixed direct airflow, significantly improving passenger comfort and health, and addressing the core pain points of existing technologies.

[0145] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
