Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of vehicle windows, and in particular relates to a vehicle window air guide device, an automobile, and a control method of the vehicle window air guide device. BACKGROUND

[0002] When the automobile is left in an open environment for a long time (such as a summer sun exposure scene), complete closure of the vehicle window will form a closed space in the vehicle, and heat cannot be effectively dissipated, resulting in a sharp rise in the temperature in the vehicle (often 20-30 DEG C higher than the outside temperature). At this time, the user needs to rely on the air conditioner for a long time to cool down before normal driving, which not only causes energy waste, but also brings strong discomfort to the driver and passengers due to the initial high temperature, and the interior of the vehicle in a high-temperature environment may release harmful substances, which poses a certain health and safety hazard; if the window is opened in advance for heat dissipation, dust, fallen leaves and other debris will enter the vehicle, increasing the cleaning burden. When the vehicle is driving, if the window is opened for ventilation due to heat, the outside airflow will directly flow into the vehicle, forming strong wind noise and affecting the driving experience; at the same time, fine rain, small stones or dust splashed from the roadside during driving will enter the vehicle through the window opening, polluting the interior or causing slight injury to the personnel.

[0003] When the outside temperature is suitable (such as spring and autumn), the user needs to open the window for rest in the vehicle, and the existing vehicle window structure cannot meet the demand: complete opening of the window can ensure ventilation, but flying insects and reptiles can easily enter the vehicle through the window, affecting the rest comfort; if the window is closed, the air circulation in the vehicle is poor, and long-term stay can easily lead to oxygen deficiency or heat, especially for drivers who need to take a short nap, it is difficult to balance the dual needs of ventilation and anti-disturbance. In summary, the single on-off state of the existing vehicle window cannot adapt to the diversified scenes of "sun exposure and heat dissipation", "driving ventilation and protection", "parking and resting to prevent disturbance", and the like.

[0021] When the car is parked for a long time in an open environment (such as a summer sun exposure scene), the complete closure of the car window will form a closed space in the car, and the heat cannot be effectively dissipated, resulting in a sharp rise in the temperature in the car (often exceeding the outside temperature by 20-30 DEG C). At this time, the user needs to rely on the air conditioner for a long time to cool down before normal driving, not only causing energy waste, but also causing strong discomfort to the driver and passengers due to the initial high temperature, and the interior of the car in a high-temperature environment may release harmful substances, which poses a certain health and safety hazard; if the window is opened in advance for heat dissipation, dust, leaves and other debris will enter the car, increasing the cleaning burden. Moreover, during the driving process, if the car window needs to be opened for ventilation due to the heat, the outside airflow will directly flow into the car, causing strong wind noise and affecting the driving experience; at the same time, fine rain, small stones or dust splashed from the roadside during driving will enter the car through the window opening, polluting the interior or causing slight injury to the personnel. In addition, when the outside temperature is suitable (such as spring and autumn), the user needs to open the window for rest in the car, and the existing window structure cannot meet the demand: completely opening the window can ensure ventilation, but flying insects and reptiles can easily enter the car through the window, affecting the comfort of rest; if the window is closed, the air circulation in the car is poor, and long-term stay can easily cause oxygen deficiency or heat, especially for drivers who need to take a short nap, it is difficult to balance the dual needs of ventilation and anti-disturbance. In summary, the single on-off state of the existing car window cannot adapt to the diversified scenes such as "sun exposure and heat dissipation", "driving ventilation and protection", "parking and rest anti-disturbance" and the like.

[0022] Therefore, the present application provides a car window air guide device, a car and a control method of the car window air guide device, aiming to solve the problem that the existing car window cannot balance the ventilation and protection needs in different scenes.

[0023] Please refer to Figure 1 The car window air guide device 100 comprises a first storage assembly 1, an air guide assembly 2 and a first clamping assembly 3. The first storage assembly 1 comprises a first storage box 11 and a first winding assembly 12 arranged in the first storage box 11; the air guide assembly 2 comprises a wind direction driving shaft 21, a plurality of air guide pieces 22 and a plurality of penetrating shafts 23, each air guide piece 22 is arranged along the horizontal direction, each penetrating shaft 23 is correspondingly penetrated in each air guide piece 22 along the vertical direction, and the wind direction driving shaft 21 is sequentially penetrated in each air guide piece 22 along the horizontal direction to synchronously drive each air guide piece 22 to rotate around the corresponding penetrating shaft 23; the upper end of each penetrating shaft 23 is connected to the first winding assembly 12; the first clamping assembly 3 is used for detachably clamping the top end of the car window glass 200, and the lower end of each penetrating shaft 23 is connected to the first clamping assembly 3; wherein the bottom end of each penetrating shaft 23 is connected to the first clamping assembly 3, and each air guide piece 22 and each penetrating shaft 23 can deform to enter the first storage box 11 with the upward and downward movement of the car window glass 200 and the rotation drive of the first winding assembly 12.

[0024] In practical application, when the vehicle window glass 200 is in an open state, the first clamping assembly 3 is clamped and fixed with the top end of the vehicle window glass 200, at this time, the air adjusting sheet 22 and the penetrating shaft 23 are driven by the first clamping assembly 3 to extend out of the first storage box 11, forming a wind guide barrier at the vehicle window opening. When the vehicle window needs to be closed, the vehicle window glass 200 moves upward, and the first clamping assembly 3 rises, at this time, the first winding assembly 12 gradually winds the penetrating shaft 23 and the air adjusting sheet 22 upward. Since the air adjusting sheet 22 and the penetrating shaft 23 are designed by using a deformable material, they will naturally fold and gather during the winding process, enter the storage box through the opening of the first storage box 11, and finally, along with the complete closing of the vehicle window glass 200, the air adjusting assembly 2 is stored in the first storage box 11, without affecting the normal closing of the vehicle window.

[0025] Moreover, since the first clamping assembly 3 is detachably connected to the top end of the vehicle window glass 200, the user can flexibly choose whether to install the air guide device according to actual use requirements. When the air guide function is not needed, the user only needs to remove the clamping relationship between the first clamping assembly 3 and the vehicle window glass 200, and then stores the air adjusting assembly 2 in the first storage box 11, so that the original use state of the vehicle window can be restored, avoiding any interference with the normal lifting function of the vehicle window.

[0026] Therefore, through the modular structure design and the deformable air adjusting assembly 2, the embodiment of the present application realizes the functional requirements of ventilation and protection in different scenes, which is embodied in the following aspects: Firstly, the structure design realizes the dual functions of ventilation and protection. Specifically, the combined design of the first storage assembly 1, the air adjusting assembly 2 and the first clamping assembly 3 enables the air adjusting assembly 2 to form a wind guide barrier when the vehicle window is opened. The multiple horizontally arranged air adjusting sheets 22 rotate around the penetrating shaft 23 under the synchronous driving of the wind direction driving shaft 21 (the driving mode of the wind direction driving shaft 21 can be manual or electric adjustment), which can flexibly adjust the angle and rate of air flow entering the vehicle: in the summer sun scenario, the air adjusting sheets 22 can be adjusted to a large angle ventilation state to accelerate the exchange of hot air in the vehicle and the outside air, quickly reduce the temperature in the vehicle, and the physical barrier formed by the air adjusting sheets 22 can block dust and fallen leaves from entering; when the vehicle is running, the air adjusting sheets 22 can be adjusted to a smooth wind angle to avoid wind noise caused by direct air flow, and also can intercept flying rain, small stones and dust, preventing interior pollution and slight injury to personnel; in the spring and autumn seasons, the air adjusting sheets 22 can be kept in a small angle ventilation state to ensure air circulation in the vehicle, while blocking flying insects and reptiles from entering, meeting the ventilation and anti-interference requirements. Second, the deformable characteristics and the storage design do not affect the normal use of the vehicle window. The air adjusting piece 22 and the penetrating shaft 23 are made of a deformable material, and are driven by the rolling drive of the first rolling assembly 12, so that the air adjusting assembly 2 can be flexibly rolled up or rolled out along with the up-down movement of the vehicle window glass 200. When the vehicle window is closed, the air adjusting assembly 2 can be smoothly rolled up and entered into the first storage box 11, and does not hinder the normal closing of the vehicle window. When the vehicle window is opened, the first clamping assembly 3 is clamped and fixed with the top end of the vehicle window glass 200, and the air adjusting assembly 2 can be quickly extended to form a wind guiding barrier, so as to realize the compatibility of the wind guiding function and the original lifting function of the vehicle window. Third, the detachable design improves the use flexibility. Specifically, the detachable clamping structure of the first clamping assembly 3 and the top end of the vehicle window glass 200 allows the user to independently select whether to use the wind guiding device according to the actual needs. When the wind guiding function is not needed, the clamping relationship is released and the air adjusting assembly 2 is stored in the first storage box 11, so that the original use state of the vehicle window can be restored, and the practicability and adaptability of the product are improved. In summary, the present application integrates the functions of ventilation, wind guiding, protection and storage into one, and can adapt to various scenes such as “exposure and heat dissipation”, “driving ventilation and protection”, “parking rest and anti-interference”, etc. The present application not only solves the use pain points of the existing vehicle window, but also takes into account the flexibility and convenience of use, and significantly improves the comfort and safety of automobile driving and riding.

[0027] In some embodiments, the first rolling assembly 12 includes a first rolling roller, a first rolling spring 122 and a first fixed seat. The first fixed seat is fixedly arranged in the interior of the first storage box 11, the first rolling roller is rotationally connected to the first fixed seat, and the first rolling spring 122 is sleeved on the first rolling roller and connected to the first rolling roller at one end and to each penetrating shaft 23 at the other end. When the first rolling roller rotates, the first rolling spring 122 rotates with the first rolling roller and drives each penetrating shaft 23 and each air adjusting piece 22 to roll up or extend into the first storage box 11.

[0028] When the vehicle window glass 200 is opened downward, the first clamping assembly 3 moves downward synchronously with the vehicle window glass 200: the first clamping assembly 3 pulls each penetrating shaft 23 to move downward, and the penetrating shaft 23 drives the first rolling roller to rotate in the first direction (such as clockwise) through the connected first rolling spring 122. At this time, the first rolling spring 122 is gradually stretched or twisted along with the rotation of the first rolling roller, forming an energy storage state; at the same time, each penetrating shaft 23 gradually extends out of the first storage box 11 under the action of the tension, driving each air adjusting piece 22 to expand synchronously, until the vehicle window glass 200 stops moving downward, and the air adjusting piece 22 forms a stable wind guiding barrier at the vehicle window opening, and the angle of the air adjusting piece 22 can be adjusted through the wind direction driving shaft 21 to realize the wind guiding function. When the window glass 200 is closed upward, the first clamping assembly 3 moves upward synchronously with the window glass 200: the downward pulling force of the first clamping assembly 3 on the penetrating shaft 23 gradually decreases, at this time the first coil spring 122 in the energy storage state releases energy, and drives the first winding roller to rotate in the second direction opposite to the first direction (for example, counterclockwise rotation). The reverse rotation of the first winding roller drives each penetrating shaft 23 to move upward through the first coil spring 122, and the penetrating shaft 23 drives each air deflector 22 to be folded into the first storage box 11; as the window glass 200 continues to move upward, the penetrating shaft 23 and the air deflector 22 are gradually completely wound into the first storage box 11, until the window glass 200 is completely closed, and the storage state of the air deflector assembly 2 does not affect the sealing of the closed window.

[0029] In addition, the rotating connection between the first fixed seat and the first winding roller can be achieved by setting a bearing structure, so as to reduce the friction resistance when the first winding roller rotates, improve the smoothness of the process of driving the penetrating shaft 23 to fold or extend by the first coil spring 122, and reduce the risk of window lifting jamming or air deflector assembly 2 movement blocked due to excessive friction.

[0030] In some embodiments, please refer to Figure 2 The first storage box 11 has a first storage opening 111 for the plurality of air deflectors 22 and the plurality of penetrating shafts 23 to enter, the first storage opening 111 faces downward, and the size of the first storage opening 111 gradually increases from top to bottom. This design makes the air deflector assembly 2 more smoothly pass through the first storage opening 111 into the inside of the first storage box 11 during the folding process, avoiding the risk of component jamming due to the small opening size.

[0031] In some embodiments, please refer to Figure 3 and Figure 4The first clamping assembly 3 comprises a first frame 31, a first pressing block 32, a first clamping buckle 33, a first reset spring 34 and a clamping driving member. The first frame 31 is connected to the lower end of each through shaft 23. One end of the first frame 31 towards the vehicle window glass 200 is provided with a first opening 311. The first pressing block 32 is movably connected to the first frame 31 along the vertical direction. One end of the first clamping buckle 33 is movably arranged on the inner side of the first frame 31 in the horizontal direction, and the other end thereof protrudes from the first opening 311 of the first frame 31 to be clamped to the vehicle window glass 200. The first reset spring 34 is arranged to extend along the horizontal direction, and one end thereof abuts against the inner side of the first frame 31, and the other end thereof abuts against the first clamping buckle 33, so as to provide the first clamping buckle 33 with an elastic clamping force towards the vehicle window glass 200. The fixed end of the clamping driving member is slidably arranged on the side of the window frame, and the movable end thereof is connected to the first pressing block 32 to drive the first pressing block 32 to move up and down. The side of the first clamping buckle 33 towards the first opening 311 is provided with a first inclined surface 331, and the first pressing block 32 abuts against the first inclined surface 331. When the first pressing block 32 moves in the vertical direction, the first clamping buckle 33 is pushed to move in the horizontal direction to clamp or release the vehicle window glass 200.

[0032] The working principle of the first clamping assembly 3 is as follows: ① pressing block movement and inclined surface force conversion: the movable end of the clamping driving member drives the first pressing block 32 to move in the vertical direction (such as upward pulling), and the lower end of the first pressing block 32 is pressed against the first inclined surface 331 of the first clamping buckle 33. Since the first inclined surface 331 is an inclined structure (such as "narrow at the top and wide at the bottom"), the vertical pulling force of the pressing block is guided by the inclined surface and converted into a horizontal pushing force (towards the inner side of the first frame 31) of the first clamping buckle 33. ② clamping buckle contraction and glass unlocking: the horizontal pushing force forces the first clamping buckle 33 to contract inwards against the elastic force of the first reset spring 34, and the outer end thereof completely separates from the glass edge, so that the clamping relationship between the clamping buckle and the glass is released. At this time, the user can easily take the first frame 31 from the top end of the glass to complete the disassembly. ③ component reset and preparation for next time: after the driving member is released or the driving signal is stopped, the first reset spring 34 pushes the first clamping buckle 33 to extend out of the first opening 311 again, and the first pressing block 32 returns to the initial position under the reaction force of the first reset spring 34 (or the reset force of the driving member); the fixed end of the clamping driving member can slide along the window frame to the initial position, waiting for the next use.

[0033] In this way, the original function of the vehicle window is avoided to be interfered, the "lossless adaptation" is realized, and the safety of the vehicle is ensured.

[0034] In this component, an anti-slip rubber pad can be added to the side of the first buckle 33 facing the glass (in conjunction with the first return spring 34 for flexible clamping) to avoid hard contact that could scratch the glass; at the same time, after unlocking, the component can be completely detached from the glass, and does not occupy the window lifting space when stored, and the locking drive component slides along the window frame without interfering with the operation of core components such as the window guide rail and the lifting motor.

[0035] Furthermore, the inner wall of the first frame 31 is provided with a groove extending in the horizontal direction, and the first buckle 33 is slidably connected in the groove.

[0036] The sliding groove provides a stable horizontal sliding track for the first latch 33, which can limit the offset of the first latch 33 during movement, so that the first latch 33 moves in the direction toward or away from the window glass 200, avoiding problems such as unstable engagement or difficulty in unlocking caused by the first latch 33 shaking.

[0037] In some embodiments, please refer to Figure 3 and Figure 4 The top of the first frame 31 is provided with a through hole facing up and down, and the first pressure block 32 passes through the through hole. The diameter of the through hole is slightly larger than the cross-sectional size of the first pressure block 32, so that the first pressure block 32 can move up and down smoothly in the through hole and reduce frictional resistance during the movement.

[0038] In some embodiments, please refer to Figure 2 A wind direction sensor 4 and a wind direction drive are provided at intervals on the outer side of the first frame 31. The wind direction sensor 4 is used to detect the external wind direction. The wind direction drive is connected to the wind direction drive shaft 21 to drive the wind direction drive shaft 21 to rotate, thereby driving each wind vane 22 to rotate synchronously around the corresponding through shaft 23.

[0039] Real-time wind direction detection: Wind direction sensors 4 (such as miniature ultrasonic wind direction sensors or Hall effect wind direction sensors) are spaced apart on the outer side of the first frame 31. They can capture the flow direction (such as frontal wind, side wind, and diagonal wind) and wind speed in real time, and convert the detected wind direction data into electrical signals (such as voltage signals or digital signals), which are then transmitted to the control unit (such as a microcontroller MCU) of the wind direction drive component. Drive signal processing: After receiving the signal from the wind direction sensor 4, the control unit generates a corresponding drive command according to the preset "wind direction - wind vane 22 angle" matching logic (such as adjusting the wind vane 22 angle to 30°-45° when there is frontal wind and adjusting it to 15°-20° when there is side wind), and sends it to the wind direction drive component (such as a miniature stepper motor or servo motor). Synchronous adjustment of the wind adjusting pieces 22: after the wind direction driving member receives the instruction, it drives the wind direction driving shaft 21 connected thereto to rotate around the horizontal axis; since the wind direction driving shaft 21 is sequentially arranged in each wind adjusting piece 22, its rotation will synchronously drive all the wind adjusting pieces 22 to rotate around the corresponding penetrating shaft 23, so as to adjust the whole wind adjusting piece 22 to the angle adapted to the current wind direction, and complete the wind direction adjustment. Dynamic real-time adaptation: when the external wind direction changes (such as the change of crosswind direction caused by lane changing or driving route turning of the vehicle), the wind direction sensor 4 will continuously detect and transmit the new wind direction data, and the control unit will adjust the driving instruction in real time according to the changed wind direction, so as to dynamically optimize the angle of the wind adjusting piece 22 according to the wind direction, and always keep the best wind guiding state.

[0040] In some embodiments, please refer to Figure 2 , further comprising a second storage assembly 5, a screen 6 and a second clamping assembly 7, the second storage assembly 5 is used for mounting on the top end of the window frame body, and the second storage assembly 5 is arranged independently in the horizontal direction with respect to the first storage assembly 1; the second storage assembly 5 comprises a second storage box 51 and a second winding assembly 52 arranged in the second storage box 51; the top end of the screen 6 is connected to the second storage assembly 5, and the bottom end of the screen 6 is connected to the second clamping assembly 7; wherein the second clamping assembly 7 is used for detachably clamping on the top end of the window glass 200, and the screen 6 can enter the second storage box 51 along with the up and down movement of the window glass 200 and the rotation driving of the second winding assembly 52.

[0041] The first storage assembly 1, the wind adjusting assembly 2 and the first clamping assembly 3 can be arranged on the outer side of the window glass 200. The second storage assembly 5, the screen 6 and the second clamping assembly 7 can be arranged on the inner side of the window glass 200.

[0042] The working principle of the second storage assembly 5 is similar to that of the first storage assembly 1. When the vehicle window glass 200 is in an open state, the second clamping assembly 7 is clamped and fixed to the top end of the vehicle window glass 200, and the screen 6 is extended out of the second storage box 51 under the driving of the second clamping assembly 7, forming a protective screen located inside the vehicle window opening. When the vehicle window is closed, the second clamping assembly 7 moves upward with the vehicle window glass 200, and the second winding assembly 52 gradually winds the screen 6 upward. Since the screen 6 has flexibility, it can be smoothly rolled up and into the second storage box 51, without affecting the normal closing of the vehicle window. The arrangement of the screen 6 further expands the function of the device. While the air deflector 22 realizes air deflection and basic protection, the screen 6 can more effectively block small debris such as mosquitoes, willow catkins, etc. from entering the vehicle, especially when parking and ventilating at night in summer or driving with the window open in spring and autumn. This can prevent flying insects from directly contacting the driver and passenger, and improve the comfort of use. In addition, the second storage assembly 5 and the first storage assembly 1 are independently arranged, and the user can individually enable the air deflection function or the screen 6 protection function according to actual needs, or simultaneously enable them, further enhancing the scene adaptability of the product.

[0043] The embodiment of the present application also provides an automobile. The automobile includes a vehicle body, a vehicle window frame, a vehicle window glass 200, and a vehicle window air deflector 100 in any of the above embodiments. The vehicle window frame is mounted on the vehicle body, the vehicle window glass 200 is arranged in the vehicle window frame in a lifting manner, and the first storage assembly 1 and the second storage assembly 5 (if provided) of the vehicle window air deflector 100 are respectively fixed to the top end of the vehicle window frame, and the first clamping assembly 3 and the second clamping assembly 7 (if provided) are detachably connected to the top end of the vehicle window glass 200. By integrating the vehicle window air deflector 100, the automobile obtains diversified ventilation, air deflection and protection capabilities on the basis of retaining the original vehicle window lifting function, can be flexibly adjusted according to different use scenes, effectively improves the comfort and safety of the driver and passenger, and enhances the market competitiveness of the whole vehicle.

[0044] Further, the top end of the vehicle window glass 200 is provided with a clamping groove or a clamping hole on both sides, which is matched with the clamping structure of the first clamping assembly 3 and the second clamping assembly 7. When the first clamping assembly 3 or the second clamping assembly 7 needs to be fixed, the clamping buckle can be inserted into the corresponding clamping groove or clamping hole, forming a stable mechanical connection, preventing the clamping assembly from loosening due to bumps or air flow impact during vehicle driving.

[0045] The embodiment of the present application also provides a control method of a vehicle window air deflector.

[0046] Please refer to Figures 1 to 4The method is applied to the above-mentioned vehicle window air guide device 100, and comprises the following steps: the wind direction sensor 4 collects wind direction data and calculates a target rotation direction and a target rotation angle and transmits them to the wind direction driving member, and the wind direction driving member drives the wind direction driving shaft 21 to rotate according to the target rotation direction and the target rotation angle, so as to guide the airflow to avoid the vehicle window opening. When the vehicle window glass 200 moves upwards, the winding roller reverses rotation, and pulls the air regulating piece 22 and the penetrating shaft 23 to gradually fold upwards and enter the first storage box 11. When the vehicle window glass 200 moves downwards, the winding roller reverses rotation, and the penetrating shaft 23 and the air regulating piece 22 gradually unfold downwards under the action of gravity of the first clamping assembly 3 and extend out of the first storage box 11.

[0047] For example, when a head-on wind (the angle between the wind direction and the vehicle driving direction is ≤30°) is detected and the wind speed is ≤5 m / s, the target rotation direction is “clockwise” (in the perspective of the vehicle interior), and the target rotation angle is 30°-45°, so as to guide the airflow to smoothly enter the vehicle interior along the upper part of the vehicle window and avoid directly blowing on the driver and the passenger; if the wind speed is >5 m / s, the target rotation angle is adjusted to 15°-20°, so as to reduce the dust brought by strong wind or wind noise. When a side wind (the angle between the wind direction and the vehicle driving direction is >30°) is detected, the target rotation direction is “counterclockwise”, and the target rotation angle is fine-tuned according to the side wind direction (for example, the angle is adjusted to 10°-15° when a left side wind is detected, and the angle is adjusted to 20°-25° when a right side wind is detected), so as to weaken the interference of the side wind on the airflow in the vehicle interior and maintain the balance of the airflow. When a reverse wind is detected (for example, when the vehicle reverses), the target rotation angle is adjusted to 0° (the air regulating piece 22 is vertically closed), so as to avoid the airflow from pouring into the vehicle interior in the reverse direction and prevent dust and sundries from entering.

[0048] The control method realizes the automatic and intelligent control of the vehicle window air guide device 100 through the cooperation of sensor sensing, logical judgment and actuator driving, and further improves the convenience and scene adaptability of the user.

[0049] In some embodiments, referring to Figures 1 to 4 The control method of the vehicle window air guide device 100 further comprises the following steps: when the vehicle window glass 200 moves upwards, the second clamping assembly 7 moves upwards synchronously with the vehicle window glass 200, the second winding assembly 52 in the second storage assembly 5 reverses rotation, gradually winds the screen 6 and enters the second storage box 51. When the vehicle window glass 200 moves downwards, the second winding assembly 52 reverses rotation and releases the screen 6, and the screen 6 unfolds and extends out of the second storage box 51 under the action of gravity of the second clamping assembly 7 synchronously with the vehicle window glass 200.

[0050] For example, in the scenario of a short lunch break in the car in spring and autumn, the control method can realize the automatic protection of "opening the window to deploy the screen 6, closing the window to roll up the screen 6", the specific process is as follows: Initial state: the window glass 200 is in a fully closed state, the second clamping assembly 7 is clamped at the top end of the window glass 200, the second winding assembly 52 winds the screen 6 completely into the second storage box 51 (the storage box is usually installed on the upper edge of the window, arranged side by side with the first storage box 11), and the screen 6 has no external exposure, which does not affect the appearance and normal closing of the window. The window moves down and the screen 6 is deployed synchronously: The driver presses the window lift button to control the window glass 200 to move down (e.g. to 1 / 3 height to meet the ventilation requirement). At this time, the window glass 200 drives the second clamping assembly 7 to move down synchronously, and the second clamping assembly 7 pulls the screen 6 under the action of gravity; at the same time, the second winding assembly 52 (including the second winding roller and the second winding spring) in the second storage box 51 receives the window down signal (obtained through displacement sensor or CAN bus) and immediately reverses and releases the screen 6. The screen 6 moves down vertically along the inner side of the window glass 200 under the traction of the gravity of the second clamping assembly 7 and the release of the second winding assembly 52, gradually extends out of the second storage box 51, and finally stably deploys with the window glass 200 stopping moving down. At this time, the deployed screen 6 completely covers the window opening area (e.g. the screen 6 is deployed to 30 cm height synchronously for a 30 cm high window opening), forming a physical barrier that can ensure fresh air from outside to enter the car through the gap of the screen 6 (to meet the ventilation requirement) and block insects and reptiles (such as mosquitoes and ants) from entering the car to avoid disturbing the driver's lunch break. The window moves up and the screen 6 is wound synchronously: After the driver finishes the lunch break, the driver presses the window lift button to control the window glass 200 to move up (to close the window). The window glass 200 drives the second clamping assembly 7 to move up synchronously, and the second winding assembly 52 reverses (winding direction) after receiving the window up signal, and the second winding spring releases the stored energy to drive the second winding roller to rotate, gradually winding the screen 6 upwards. Since the screen 6 is made of light and foldable nylon material, it will be tightly wound along the axis of the second winding roller during winding, and gradually enter the second storage box 51; when the window glass 200 is completely closed, the second clamping assembly 7 returns to the initial position at the top end of the window, and the screen 6 is completely wound into the second storage box 51, with no excess screen 6 exposed, which does not affect the complete closing and sealing of the window. For example, in the scenario of low-speed driving (such as moving a car in a community or slow driving in a congested road) and ventilation in summer: When the driver opens the window glass 200 (e.g. moves it 5 cm downwards to avoid wind noise at high speed), the second winding assembly 52 synchronously releases the gauze 6, and the gauze 6 is unfolded 5 cm downwards with the window glass 200 to cover the narrow window opening. At this time, the outside airflow can enter the vehicle through the gauze 6 to achieve slight ventilation, while preventing mosquitoes in roadside grass from entering the vehicle through the window opening; when the vehicle accelerates to high speed (e.g. more than 60 km / h), the driver controls the window glass 200 to close upwards, and the second winding assembly 52 immediately rotates forward to wind the gauze 6, and the gauze 6 is quickly stored in the second storage box 51 with the window closing, to avoid the gauze 6 being blown by the airflow to produce abnormal sound or deformation when driving at high speed. As can be seen from the above scenarios, the winding and unwinding of the gauze 6 is completely synchronized with the lifting action of the window glass 200, without the need for the user to additionally operate the gauze 6 switch, which meets the dual needs of "ventilation + anti-interference" in different scenarios, and maintains the convenience of operation, and forms a complementary function with the air regulating assembly 2 (the air regulating assembly 2 is responsible for air guiding and protection, and the gauze 6 is responsible for mosquito prevention and small debris prevention), which further improves the scene adaptation capability of the window air guiding device 100. The above-described embodiments are merely exemplary embodiments of the present application, and do not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
