Description

Technical Field

[0001] This application belongs to the field of air conditioning vents for new energy vehicles, and specifically relates to a novel vehicle air conditioning vent device and operating system. Background Technology

[0002] The rapid development of the new energy vehicle industry has transformed vehicles from simple means of transportation into multifunctional mobile spaces that integrate travel, leisure, and daily living, thanks to their capabilities such as high-power external discharge and long-term parking power supply.

[0003] Nowadays, many car owners drive new energy vehicles for travel and camping, using their vehicles as mobile homes. In outdoor settings, wet hair and clothes urgently need to be dried quickly, but traditional hair dryers are inconvenient to carry and often cannot be used in a timely manner.

[0004] In the current technological solution, the vehicle's air conditioning vents are rigidly fixed inside the instrument panel (IP), and their airflow direction depends entirely on the adjustment of the internal guide vanes. This fixed structure means that the vents cannot be moved freely, making it extremely inconvenient when users need to locally dry specific items (such as hair or clothing) at close range, failing to simulate the flexibility and convenience of a traditional handheld hair dryer. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a novel vehicle air conditioning vent device and operating system, featuring a handheld blowing mode that allows the vent frame to be held and moved in a convenient manner for blowing operations.

[0006] A novel vehicle air conditioning vent device and operating system includes a main air duct, an instrument panel, and an air vent frame body. The main air duct is located within the instrument panel, and the air vent frame body is fitted to the air outlet of the instrument panel. A corrugated pipe is provided between the main air duct and the air vent frame body. Both ends of the corrugated pipe are connected to the main air duct and the air vent frame body respectively by bolts or snap-fit ​​connections, and the main air duct and the air vent frame body are interconnected through the corrugated pipe. Positioning protrusions are installed on both side walls of the air vent frame body. A pair of symmetrically distributed spiral guide rails are installed on the instrument panel. The positioning protrusions are slidably mounted on the spiral guide rails. The positioning protrusions are pushed back and forth by a drive structure.

[0007] Preferably, an end crossbar is installed inside the instrument panel; an elastic rope connects the end crossbar and the air outlet frame body.

[0008] Preferably, the drive structure includes a motor; the motor is disposed inside the instrument panel; the output end of the motor is provided with a worm gear transmission mechanism; the bottom end of the positioning protrusion is inlaid with a threaded structure; the threaded structure of the positioning protrusion and the worm gear transmission mechanism mesh with each other.

[0009] Preferably, the positioning protrusion and the spiral guide rail are fitted with a clearance, and foam is provided in the clearance.

[0010] Preferably, the air outlet frame body is fitted to the opening of the dashboard, and sealing foam is installed on the inner side wall of the air outlet frame body.

[0011] Preferably, the instrument panel is provided with multiple air outlets, some of which are equipped with corrugated pipes, positioning protrusions, threaded structures, spiral guide rails, motors, worm gear transmission mechanisms, end crossbars, elastic ropes, bolts and air outlet frame bodies, serving as the end of a handheld hair dryer.

[0012] Preferably, a novel vehicle air conditioning vent operating system controls the aforementioned novel vehicle air conditioning vent device, including a vehicle control module; the vehicle control module is equipped with a handheld hair dryer mode, which controls the air blowing state of the vent body; the handheld hair dryer mode includes a motor control module and an air volume centralization module.

[0013] Preferably, the motor control module controls the drive of the motor; the air volume centralized module controls the opening and closing of the air damper at the air outlet of the instrument panel.

[0014] Preferably, the trigger command for the handheld hair dryer mode is: When the first-level operation command is triggered: the handheld hair dryer mode is triggered for the first time. The air volume concentration module closes the air dampers of the other air outlets and only opens the air damper of the air outlet frame body. At the same time, the motor control module drives the motor to rotate forward, causing the air outlet frame body to extend outward along the loop guide rail for handheld removal. When the second-level operation command is triggered: the handheld hair dryer mode is triggered for the second time, the HVAC assembly starts to supply air, and the airflow is blown out from the extended air outlet frame body through the main air duct and the corrugated pipe; When the third-level operation command is triggered: the handheld hair dryer mode is triggered for the third time, the motor control module drives the motor to reverse, which drives the air outlet frame to return to the instrument panel. At the same time, the vehicle control module releases the air damper of the other air outlets from the closed state.

[0015] Preferably, in the motor control module, the theoretical working time of the motor required for the air outlet frame body to move from the initial position to the end position is t0. In actual vehicle applications, the actual running time of the motor is set to t1, and t1>t0.

[0016] Compared with the prior art, this application has the following advantages: The entire system uses the dashboard as its mounting base, with a main air duct installed internally. The air outlet frame is mounted at the air outlet position on the dashboard. The main air duct and the air outlet frame are connected by a corrugated pipe, which is reinforced at both ends with bolts or clips. Symmetrical positioning protrusions are arranged on the back of the air outlet frame, forming a precise sliding pair with the loop guide rail on the dashboard. The entire unit moves back and forth thanks to a matching drive structure. The corrugated pipe has excellent expansion and contraction performance, ensuring smooth airflow throughout the entire process while providing room for the air outlet frame to be pulled out and moved, perfectly suited for handheld use. The symmetrical loop guide rail and positioning protrusion structure ensure even force distribution on the air outlet, resulting in smooth and stable sliding without any deviation or jamming.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] like Figure 2 right side and Figure 3 As shown on the right, a novel vehicle air conditioning vent device includes a main air duct 1, an instrument panel 2, and an air vent frame body 3. The main air duct 1 is located inside the instrument panel 2, and the air vent frame body 3 is fitted to the air vent of the instrument panel 2. A corrugated pipe 4 is provided between the main air duct 1 and the air vent frame body 3. The two ends of the corrugated pipe 4 are connected to the main air duct 1 and the air vent frame body 3 respectively by bolts 5 or snap-fit, and the main air duct 1 and the air vent frame body 3 are interconnected through the corrugated pipe 4. Positioning protrusions 6 are installed on both side walls of the air vent frame body 3. A pair of symmetrically distributed loop guide rails 7 are installed on the instrument panel 2. The positioning protrusions 6 are slidably mounted on the loop guide rails 7. The positioning protrusions 6 are pushed back and forth by a drive structure. like Figure 1 As shown, Figure 1 On the left is the basic structure of a vehicle air conditioner, which mainly consists of an HAVC assembly, air ducts, and air vents. The hot / cold air generated by the HAVC is transferred to the vehicle interior through the corresponding air ducts and air vents to achieve the functions of heating and cooling the vehicle interior. Generally, vehicles have four air vents, with air outlet frames on the vents ( Figure 1 The right side (of the air vent) is usually fixed to the vehicle's IP (Installation Equipment). The entire air vent frame is immovable. The airflow volume and direction can be controlled by adjusting the angle of the air vent frame blades. Figure 2 left side and Figure 3 As shown on the left, it can be seen from the above that the vehicle's air conditioning vent is rigidly fixed inside the instrument panel IP. Its airflow direction depends entirely on the adjustment of the internal guide vanes. This fixed structure means that the vent cannot be moved at will, which makes it extremely inconvenient when users need to dry specific items (such as hair or clothes) locally and at close range. It cannot simulate the flexibility and convenience of a traditional handheld hair dryer. like Figure 2As shown in the right figure, in the design of this application, the entire equipment uses the instrument panel 2 as the mounting base, with the main air duct 1 arranged inside. The air outlet frame body 3 is assembled at the air outlet position of the instrument panel 2. The main air duct 1 and the air outlet frame body 3 are connected by a corrugated pipe 4, and the two ends of the corrugated pipe 4 are reinforced by bolts 5 or snap-fit. The back of the air outlet frame body 3 is symmetrically arranged with positioning protrusions 6, forming a precise sliding pair with the loop guide rail 7 on the instrument panel 2 (such as...). Figure 3 right side and Figure 4 As shown in the diagram, the entire unit moves back and forth thanks to a matching drive structure. The corrugated pipe 4 has excellent expansion and contraction performance, ensuring smooth airflow throughout the entire process while providing space for the pull-out and repositioning of the air outlet frame 3, perfectly suited for handheld use. The symmetrical spiral guide rail 7 and positioning convex strip 6 structure ensure even force distribution on the air outlet, resulting in smooth and stable sliding without any deviation or jamming issues.

[0023] An end crossbar 11 is installed inside the instrument panel 2; an elastic rope 12 is connected between the end crossbar 11 and the air outlet frame body 3. like Figure 2 As shown on the right, the end crossbar 11 is fixed at a designated position inside the instrument panel 2, serving as a fixed fulcrum for the elastic rope 12. The two ends of the elastic rope 12 are respectively bound to the end crossbar 11 and the air outlet frame body 3. Following the movement of the air outlet frame body 3, it completes the stretching and rebounding actions. When the air outlet frame body 3 is driven outward by the motor 9, the elastic rope 12 is stretched and stores elastic potential energy. When the air outlet frame body 3 needs to retract, the elastic rope 12 releases the stored elastic force, actively pulling the air outlet frame body 3 back into the instrument panel 2, effectively sharing the workload of the motor 9. The load is reduced, the operating loss of motor 9 is reduced, and the retraction of bellows 4 is facilitated. In the scenario where the user manually assists in the return, the elastic rope 12 can also greatly reduce the pushing and pulling resistance, making the operation easier and less strenuous. The component is small in size and can be installed in the narrow space inside the dashboard 2 without occupying the space of the driving and riding area. It has a simple structure, low cost and is not easily damaged. At the same time, the assistance of the elastic rope 12 makes the reciprocating motion of the air outlet frame body 3 smoother, improving the overall user feel and smooth operation of the product. It is an optimized design that takes into account both practicality and economy.

[0024] like Figure 5 As shown, the drive structure includes a motor 9; the motor 9 is installed inside the instrument panel 2; the output end of the motor 9 is provided with a worm gear transmission mechanism 8; the bottom end of the positioning protrusion 6 is inlaid with a threaded structure 10; the threaded structure 10 of the positioning protrusion 6 and the worm gear transmission mechanism 8 mesh with each other; The motor 9 serves as the sole power source, transmitting its rotational power to the worm gear transmission mechanism 8. Through the meshing of the worm gear transmission mechanism 8 and the threaded structure 10, the rotational motion is converted into linear reciprocating motion, driving the positioning cam 6 and the air outlet frame body 3 to extend and retract along the loop guide rail 7. This drive structure operates smoothly with low noise, meeting the requirements for quiet operation of interior components. Most importantly, the worm gear transmission mechanism 8 inherently possesses a mechanical self-locking characteristic. When the motor 9 stops working, even under external force or vehicle vibration, the transmission structure will not rotate in the opposite direction, and the air outlet frame body 3 can remain stably in its current position. This eliminates the need for additional clips, locking plates, or other components, effectively simplifying the overall mechanical structure. Furthermore, the motor 9 is concealed within the dashboard, preventing accidental contact by passengers and providing dust and impact protection, further extending the service life of the drive components and ensuring long-term stable operation.

[0025] The positioning protrusion 6 and the loop guide rail 7 are fitted with a gap, and foam is provided in the gap; The area where the positioning protrusion 6 and the loop guide 7 meet is filled with foam material. This is mainly used to solve the problem of abnormal noise and vibration caused by metal moving parts. Both the positioning protrusion 6 and the loop guide 7 are made of hard metal or hard plastic. In order to ensure smooth sliding, a reasonable assembly gap must be maintained between the two. However, the bumps and vibrations generated during vehicle operation will cause the two hard parts to rub and collide continuously, resulting in obvious abnormal noise and affecting the driving experience. The foam filling the gap is soft and can fully fill the tiny gap. Without hindering normal sliding, it buffers vibration and isolates friction, eliminating metal impact and friction noise at the source. In addition, the foam can also play a slight limiting role, reducing the amount of shaking of the parts in the gap and improving the compactness of the overall structure. This modification method is simple and efficient. It does not require modification of the main mechanical structure. The NVH performance of the whole vehicle is optimized simply by adding buffer material. It takes into account the sliding flexibility and the quietness requirements of the whole vehicle, and improves the quality and comfort of the product.

[0026] The air outlet frame body 3 is fitted to the opening of the instrument panel 2, and sealing foam is installed on the inner side wall of the air outlet frame body 3. Sealing foam is added to the inner wall of the air vent frame 3 that fits into the dashboard 2, focusing on optimizing the sealing performance and noise reduction capability of the device. When the air vent frame 3 is stored inside the dashboard 2, there will be a slight assembly gap at the joint between the two. When the vehicle is moving and vibrating, the hard contact between the air vent frame 3 and the dashboard housing can easily generate resonance noise. The sealing foam filling operation has the effect of buffering shock absorption and noise reduction, while also ensuring a sealed state.

[0027] The instrument panel 2 is provided with multiple air outlets, some of which are equipped with a corrugated pipe 4, a positioning protrusion 6, a threaded structure 10, a spiral guide rail 7, a motor 9, a worm gear transmission mechanism 8, an end crossbar 11, an elastic rope 12, a bolt 5, and an air outlet frame body 3, serving as the end of a handheld hair dryer. Instrument Panel 2 features multiple standard air conditioning vents. Some of these vents are fully equipped with a complete functional structure, including a corrugated pipe 4, sliding rail, drive motor 9, and elastic cord 12, specifically designed for handheld use as a hairdryer. The remaining vents retain their original factory-installed structure and basic functions. This differentiated design offers several advantages: it eliminates the need for large-scale modifications to the vehicle's air conditioning ductwork and the overall structure of Instrument Panel 2, significantly reducing R&D, mold, and mass production modification costs, while shortening the project implementation cycle. Secondly, it enables functional zoning management. The unmodified vents continue to provide standard cooling, heating, and ventilation, meeting the daily temperature control needs of all passengers. The dedicated vents independently function as telescopic and handheld hairdryers, with the two functions operating independently without interference. The overall layout follows the original vehicle's interior design logic, maintaining a consistent exterior style without disrupting the overall visual effect. This solution balances existing user habits with the requirements of new functions, offering reasonable modifications, strong practicality, and ease of future maintenance and troubleshooting.

[0028] A novel vehicle air conditioning vent operating system controls the aforementioned novel vehicle air conditioning vent device, including a vehicle control module; the vehicle control module is equipped with a handheld hair dryer mode, which controls the air blowing state of the vent body 3; the handheld hair dryer mode includes a motor control module and an air volume centralization module. The motor control module controls the drive of the motor 9; the air volume centralized module controls the opening and closing of the air damper at the air outlet of the instrument panel 2. like Figure 6 As shown, the trigger command for the handheld hair dryer mode is: When the first-level operation command is triggered: the handheld hair dryer mode is triggered for the first time. The air volume concentration module closes the air dampers of the other air outlets and only opens the air damper of the air outlet frame body 3. At the same time, the motor control module drives the motor 9 to rotate forward, causing the air outlet frame body 3 to extend outward along the loop guide rail 7 for handheld removal. When the second-level operation command is triggered: the handheld hair dryer mode is triggered for the second time, the HVAC assembly starts to supply air, and the airflow is blown out from the extended air outlet frame body 3 through the main air duct 1 and the corrugated pipe 4. When the third-level operation command is triggered: the handheld hair dryer mode is triggered for the third time, the motor control module drives the motor 9 to reverse, which drives the air outlet frame 3 back into the instrument panel 2. At the same time, the vehicle control module releases the air damper of the other air outlets from the closed state.

[0029] This section establishes the framework of the entire device's electronic control system, with the vehicle-mounted control module at its core. It includes a dedicated handheld blower mode and is further subdivided into a motor control module and a centralized airflow module. Each module has a clear division of labor and works collaboratively to achieve full-function intelligent control. The vehicle-mounted control module, as the central hub, receives user commands and coordinates various tasks. The centralized airflow module specifically manages the opening and closing of the dampers at all air vents throughout the vehicle, distributing and concentrating airflow. The motor control module precisely manages the start, stop, forward and reverse rotation, and runtime of motor 9, controlling the rhythm of mechanical movements. This modular electronic control design ensures a clear and organized overall control logic, with each sub-module performing its specific function. This reduces the probability of program conflicts, ensuring stable system operation. Furthermore, it allows for quick location of the corresponding functional module during later use and maintenance, simplifying the maintenance process. The entire electronic control system is integrated into the original vehicle's infotainment system, eliminating the need for an additional independent controller. It boasts high hardware integration, with the operation interface integrated into the vehicle's central control screen, conforming to the interaction habits of modern smart cars. This results in low learning costs, ease of use, and a comprehensive improvement in the level of functional intelligence.

[0030] This section specifies that the handheld hair dryer mode is triggered by the vehicle's screen and is divided into three levels of operation commands, completing airflow adjustment, mechanical actions, and mode switching step by step, thus constructing a complete automated workflow. Upon the first trigger, the airflow concentration module closes the dampers of the remaining air outlets and concentrates the airflow, while simultaneously driving motor 9 to rotate forward and push the air outlet frame 3 outward, completing all preparations before use. The second trigger activates the HVAC air conditioning assembly, and airflow blows normally from the extended vents, entering the handheld hair dryer operation state. The third trigger drives motor 9 to rotate in reverse, retracting the vents and restoring the ventilation function of all air outlets, returning the system to normal mode. This step-by-step execution logic effectively avoids action conflicts caused by simultaneous airflow switching and mechanical movement, ensuring stable and orderly equipment operation. The entire process uses touchscreen or voice triggering, eliminating cumbersome manual unlocking and plugging / unplugging operations. It boasts a high degree of automation, intuitive and simple operation, and the three-level process covers the entire scenario of "preparation—use—reset," with logic conforming to user habits. This ensures complete functionality while significantly improving operational convenience and user experience.

[0031] In the motor control module, the theoretical working time of the motor 9 required for the air outlet frame body 3 to move from the initial position to the end position is t0. In actual vehicle applications, the actual running time of the motor 9 is set to t1, and t1>t0.

[0032] Considering the structural characteristics of the worm gear transmission mechanism 8 and the speed parameters of the motor 9, we set the theoretical working time of the motor 9 required for the component to move from the initial position to the final position as t0. To ensure that the air outlet frame body 3 can be reliably fixed inside the instrument panel 2, mechanical constraints can be achieved through the self-locking characteristics of the worm gear transmission mechanism 8. On the other hand, we can also start from the software control strategy and ensure the position is in place by controlling the rotation time of the motor 9. In actual vehicle applications, we set the actual running time of the motor 9 as t1, and t1>t0 to ensure sufficient locking (to compress the sealing foam and ensure the sealing state). The specific calibration values ​​of t0 and t1 can be determined and optimized through bench testing. The actual running length of the motor 9 is greater than the theoretical running length of the air outlet frame body 3 to complete a single-pass sliding motion. In conjunction with the self-locking structure of the worm gear transmission mechanism 8, the air outlet frame body 3 is locked and positioned. At the same time, the motor 9 itself has self-locking properties. When the positioning protrusion 6 is pushed out, the rotation of the worm gear transmission mechanism 8 is in a fixed state. This means that when the positioning protrusion 6 is pushed out and pushed in, the worm gear transmission mechanism 8 is in a stationary state, which facilitates the insertion and removal of the threaded mechanism of the positioning protrusion 6 and ensures the pushing out and pushing in state of the positioning protrusion 6.

[0033] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
