Description

Technical Field

[0001] This invention relates to the field of automotive technology, specifically to an auxiliary drive side-opening device for automotive sliding doors. Background Technology

[0002] Sliding doors are mainly used in various types of vehicles, commonly found in multi-purpose vehicles, vans, and some commercial vehicles. Structurally, sliding doors use a track system to open and close the door by sliding it laterally. Compared with traditional hinged doors, they have some unique advantages. In terms of space utilization, sliding doors do not need to swing outwards when opening, which is very practical in situations where parking space is relatively narrow, preventing collisions with adjacent vehicles or obstacles when the door is open. In terms of interior space layout, sliding doors can make the door opening larger, making it easier for passengers to enter and exit the vehicle, especially for rear passengers. For vehicles with multiple passengers, this effectively improves the convenience of riding. Moreover, this opening method of sliding doors brings a unique visual effect to the vehicle's appearance, increasing the overall recognition of the vehicle.

[0003] However, in existing car sliding door systems, due to the possibility of cars being left unused for extended periods, air quality deteriorates significantly. Prolonged closure prevents air circulation, causing harmful chemicals from the interior, such as formaldehyde and benzene, to accumulate. These substances not only have a pungent odor but also pose a significant health risk, potentially leading to respiratory illnesses, allergic reactions, and even more serious health problems. Secondly, bacteria and mold easily proliferate. The humidity and temperature inside the car, in a closed environment, may be conducive to microbial growth, causing mold to easily form on seats, carpets, and other surfaces. Bacteria also multiply rapidly in corners such as the air conditioning system and vents. Once the vehicle is used again, these bacteria and mold will spread throughout the entire interior space with the airflow, affecting the health of the occupants. Furthermore, odors are difficult to dissipate. Residual food smells, cigarette smoke, or other odors mix together in a poorly ventilated environment, creating an unpleasant smell that greatly reduces the comfort of the ride.

[0004] To address this, an auxiliary drive side-opening device for automobile sliding doors is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary drive side-opening device for automobile sliding doors, in order to solve the problem mentioned in the background art that, in existing automobile side-sliding door devices, due to the possibility that the car may be left unused for a long time, the air quality will seriously deteriorate, and the long-term closure will prevent the air inside the car from circulating.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary drive side-opening device for automobile sliding doors, comprising a vehicle body, diaphragm valves, and side sliding doors disposed on both sides of the vehicle body. The side sliding doors are internally equipped with an air storage mechanism, which includes an air storage chamber and an air pump disposed inside the air storage chamber. The air storage chamber has multiple air inlets equidistantly spaced on its side for air intake, and each air inlet is internally equipped with a diaphragm valve for slow exhaust after inflation. The air storage chamber is internally fixedly connected to a top plate via multiple equidistantly arranged elastic mechanisms, and nut sleeves are fixedly connected to both ends of the top plate. When gas lifts the top plate, it drives the nut sleeves at both ends to move up and down on a threaded rod. The nut sleeves are movably connected to the threaded rod, and the nut sleeves and the threaded rod are connected via a ball nut pair, so that when the nut sleeves move up and down, they drive the threaded rod to rotate. An air intake mechanism is fixedly connected to the bottom of the air storage mechanism.

[0007] The air intake mechanism includes an air intake chamber and a rotating rod fixedly connected to a threaded rod. Three baffles are rotatably connected inside the air intake chamber, and turbines are fixedly connected to both ends of each baffle. Three worm gears matching the turbines are fixedly connected to the rotating rod so that the turbines are driven to rotate when the rotating rod rotates. Rotating shafts are also fixedly connected to both ends of the turbines so that the baffles are opened to allow air intake when the rotating rod rotates. A fragrance mechanism for filtering air is also provided on the side of the air intake chamber.

[0008] Preferably, the rotating connection between the gas storage mechanism and the rotating rod is provided with a rubber pad to increase the airtightness of the equipment, and the elastic mechanism includes a spring, a spiral telescopic tube and a gas strut, so that the top plate automatically resets after being lifted.

[0009] Preferably, the ends of the three baffles are fixedly connected with rubber sheets to prevent air intake, so as to ensure the airtightness of the vehicle body when the baffles are closed.

[0010] Preferably, an infrared sensor is provided on the side of the sliding door, and the infrared sensor is electrically connected to the air pump so that the air pump is activated to inflate when the sliding door is opened.

[0011] Preferably, the fragrance mechanism includes a filter chamber and clips fixedly connected to the upper and lower ends of the filter chamber. The side sliding door has a groove inside that matches the clips, so that the filter chamber can be quickly disassembled and replaced. The filter chamber is equipped with an activated carbon mesh for filtering. The filter chamber is connected to the vent on the air intake mechanism. Multiple equally spaced impellers are rotatably connected to the side of the filter chamber so that the impellers rotate when air is intaked.

[0012] Preferably, the wind turbine includes a fragrance component, and the fragrance component is fixedly connected inside the wind turbine shaft so that the fragrance inside the fragrance component is blown out when the wind turbine shaft rotates.

[0013] Preferably, one end of the fragrance component is fixedly connected to a handle for pulling out the fragrance component, and the side of the filter chamber is provided with a sliding groove that matches the fragrance component, so as to facilitate the disassembly and replacement of the fragrance component.

[0014] Preferably, the fragrance component includes a fragrance rod disposed on one side of the fragrance component, and an elastic rod is movably connected inside the fragrance rod via a latch. A straight rod is fixedly connected inside one side of the fan shaft. An upper convex ring matching the elastic rod is fixedly connected to the front end of the straight rod, and a lower convex ring is movably connected to the straight rod. The maximum radius of the lower convex ring is greater than the maximum radius of the upper convex ring, so that when the fragrance rod is pushed, the upper convex ring is unlocked from the latch via the lower convex ring.

[0015] Preferably, the side of the gas storage chamber is provided with an auxiliary door opening mechanism for assisting in opening the door. The auxiliary door opening mechanism includes two air chambers opened inside the gas storage chamber, and an air pipe is fixedly connected inside the air chamber. A one-way valve for gas passage is provided inside the air pipe so that the gas pressure difference drives the door to move initially. A sealing membrane to prevent air leakage is fixedly connected to the end of the air pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention improves in-vehicle air quality by incorporating an air storage mechanism, an air intake mechanism, and a fragrance mechanism inside the side sliding door. When the side sliding door is opened, the automatic inflation and air intake process is initiated, allowing fresh air to enter the vehicle. The diaphragm valve in the air storage mechanism controls the gas intake and exhaust, ensuring proper gas exchange. The baffle and turbine structure of the air intake mechanism effectively control the intake volume and mode. The activated carbon mesh in the fragrance mechanism filters impurities and harmful gases, while the fragrance component adds aroma. This series of designs effectively avoids the air quality degradation caused by prolonged vehicle parking, reduces the growth of harmful chemicals, bacteria, and mold, and provides a healthier air environment for vehicle occupants.

[0018] This invention improves air exchange efficiency through a unique mechanical transmission structure. The connection between the top plate and the nut sleeve and threaded rod in the air storage mechanism, and the cooperation between the rotating rod and the baffle and turbine in the air intake mechanism, form a highly efficient transmission system. When the side sliding door is opened, the air pump starts, and the change in gas pressure drives the top plate to move. This, in turn, causes the threaded rod to rotate through the ball nut pair, which in turn drives the rotating rod to rotate, ultimately causing the baffle to open and allow air to enter. This transmission method makes the air intake process rapid and stable, enabling a large amount of air to be exchanged in a short time, ensuring rapid air renewal inside the vehicle, and improving the exchange efficiency between the air inside the vehicle and the outside air. The effect is particularly significant when the car is turned on again after being left unused for a long time.

[0019] This invention achieves convenient maintenance and replacement through a clever design of the fragrance component structure. The fragrance component is located inside the impeller, and the fragrance is blown out when the impeller shaft rotates. The fragrance component includes a fragrance rod, a flexible rod, and other structures, which are connected by a locking mechanism. At the same time, the upper and lower convex rings on the straight rod cooperate to unlock when the fragrance rod is pushed. In addition, the side of the filter chamber has a sliding groove that matches the fragrance component, as well as a handle for pulling it out. This design makes it simple and convenient to replace the fragrance component when it is needed. Users can easily remove the fragrance component for replacement or maintenance without complicated tools or operations, reducing maintenance costs and difficulty, and improving the user experience.

[0020] This invention utilizes an auxiliary door-opening mechanism in the gas storage chamber to achieve easy initial pulling of the sliding door by taking advantage of the gas pressure difference. When the door opening action is triggered, the gas in the storage chamber flows into the air chamber through the one-way valve in the air pipe. The pressure inside the air chamber increases, creating a pressure difference with the normal pressure inside the vehicle, which pushes the door outward. This method effectively overcomes the large resistance when the traditional sliding door is initially opened, reduces manpower consumption, and makes one-handed operation more convenient. At the same time, it ensures a smooth and stable opening action, avoiding impact and jamming, and greatly improves the user's comfort when opening the door. It is especially convenient for the elderly, children, and other people with less strength or those carrying items. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1 to 8 This invention provides a technical solution for an auxiliary drive side-opening device for automotive sliding doors:

[0040] A side-opening auxiliary drive device for a car sliding door includes a car body 1, a diaphragm valve 6, and side sliding doors 2 disposed on both sides of the car body 1. The side sliding doors 2 are equipped with an air storage mechanism 3. The air storage mechanism 3 includes an air storage chamber 31 and an air pump disposed inside the air storage chamber 31. The side of the air storage chamber 31 is provided with multiple air inlets 32 for air intake at equal intervals. Each air inlet 32 ​​is provided with a diaphragm valve 6 for slowly releasing air after inflation. The air storage chamber 31 is fixedly connected to a top plate 33 through multiple elastic mechanisms 34 arranged at equal intervals. Nut sleeves 35 are fixedly connected to both ends of the top plate 33 so that when the gas lifts the top plate 33, it drives the nut sleeves 35 at both ends to move up and down on the threaded rod 36. The nut sleeves 35 are movably connected to the threaded rod 36. The nut sleeves 35 and the threaded rod 36 are connected by a ball nut pair so that when the nut sleeves 35 move up and down, they drive the threaded rod 36 to rotate. An air intake mechanism 4 is fixedly connected to the bottom of the air storage mechanism 3.

[0041] The air intake mechanism 4 includes an air intake chamber 41 and a rotating rod 45 fixedly connected to the threaded rod 36. Three baffles 42 are rotatably connected inside the air intake chamber 41, and turbines 43 are fixedly connected to both ends of the baffles 42. Three worm gears 46 that match the turbines 43 are fixedly connected to the rotating rod 45 so that the turbines 43 are driven to rotate when the rotating rod 45 rotates. The two ends of the turbines 43 are also fixedly connected to the rotating shafts 44 so that the baffles 42 are opened to allow air intake when the rotating rod 45 rotates. A fragrance mechanism 5 for filtering air is also provided on the side of the air intake chamber 41. A rubber pad is provided at the rotating connection between the air storage mechanism 3 and the rotating rod 45 to increase the airtightness of the equipment. The elastic mechanism 34 includes a spring, a spiral telescopic tube and a gas strut to automatically reset the top plate 33 after it is lifted. Rubber sheets to prevent air intake are fixedly connected to the ends of the three baffles 42 to ensure the airtightness of the vehicle body 1 when the baffles 42 are closed. An infrared sensor is provided on the side of the side sliding door 2 and is electrically connected to the air pump to start the air pump to inflate when the side sliding door 2 is opened.

[0042] During operation, when the sliding door 2 opens, its side infrared sensor quickly detects this movement. The infrared sensor detects movement based on the principle of infrared reflection or absorption. When the sliding door 2 moves, it changes the propagation path of surrounding infrared rays, thus being detected by the infrared sensor. After detecting the door opening, the infrared sensor transmits an electrical signal to the air pump, which is connected to it via a pre-set circuit. Upon receiving the signal, the air pump begins operation. Through its mechanical structure and working principle, it draws in and compresses external air, then delivers the compressed air to the air storage chamber 31 through pipes or other connections. The air storage chamber 31 has multiple air inlets 32 equidistantly spaced on its side. These air inlets 32 are designed for... To ensure even airflow into the gas storage chamber 31 and maintain uniform gas pressure distribution within it, gas enters the chamber through inlets 32. Each inlet 32 ​​contains a diaphragm valve 6. The diaphragm valve 6 operates based on the elastic deformation of a diaphragm. When gas enters, the gas pressure causes the diaphragm to deform and open the valve, allowing gas to enter the gas storage chamber 31. Once the gas pressure inside the chamber reaches a certain level, the diaphragm, under the combined action of its own elasticity and the gas pressure, gradually returns to a certain position, resulting in a slow venting state. This ensures that the gas pressure inside the chamber 31 does not become excessively high and allows for slow gas release when needed. As gas continuously enters, the pressure inside the gas storage chamber 31 gradually decreases. As the pressure gradually increases, a top plate 33 is fixedly connected inside the gas storage chamber 31 via multiple equidistantly arranged elastic mechanisms 34 (such as springs, spiral telescopic tubes, or gas struts). The function of the elastic mechanisms 34 is to provide support and restoring force to the top plate 33 when the gas pressure changes. When the gas pressure increases to a certain level, the gas will push up the top plate 33. Nut sleeves 35 are fixedly connected to both ends of the top plate 33. During the process of the top plate 33 being pushed up, the nut sleeves 35 will move on the threaded rod 36. Since the nut sleeves 35 and the threaded rod 36 are connected by a ball nut pair, which is a high-precision transmission mechanism that converts rotary motion into linear motion, when the nut sleeves 35 move up and down, the balls will roll between the threads of the nut sleeves 35 and the threaded rod 36. The rotation of the threaded rod 36 drives the rotating rod 45 in the intake mechanism 4. Three baffles 42 are rotatably connected inside the intake chamber 41 of the intake mechanism 4. Turbines 43 are fixedly connected to both ends of each baffle 42. Three worm gears 46, matching the turbines 43, are fixedly connected to the rotating rod 45. When the rotating rod 45 rotates, the meshing transmission between the worm gears 46 and the turbines 43 drives the turbines 43 to rotate. This meshing transmission is based on the gear transmission principle; the worm gear 46 acts like a screw, and the turbine 43 acts like a gear. When the worm gears 46 rotate, they push the turbines 43 to rotate. A rotating shaft 44 is also fixedly connected to both ends of the turbine 43. During the rotation of the turbine 43, the rotating shaft 44 causes the baffles 42 to unfold.This allows outside air to enter the air intake chamber 41 when the car is not in use for extended periods. The baffle 42 unfolds by rotating the shaft 44, causing the baffle 42 to rotate around its connection point with the air intake chamber 41, thereby opening the air intake passage.

[0043] As one embodiment of the present invention, such as Figure 6 and Figure 7 As shown, the fragrance mechanism 5 includes a filter chamber 51 and a retaining strip 53 fixedly connected to the upper and lower ends of the filter chamber 51. The side sliding door 2 has a groove matching the retaining strip 53 inside, so that the filter chamber 51 can be quickly disassembled and replaced. The filter chamber 51 is provided with an activated carbon mesh for filtering. The filter chamber 51 is connected to the air vent on the air intake mechanism 4. Multiple equally spaced impellers 52 are rotatably connected to the side of the filter chamber 51 so that the impellers 52 are rotated when air is intake. The impellers 52 include a fragrance component 521, and the fragrance component 521 is fixedly connected to the inside of the impeller shaft 523 so that the fragrance inside the fragrance component 521 is blown out when the impeller shaft 523 rotates. One end of the fragrance component 521 is fixedly connected to a handle 522 for pulling out the fragrance component 521. The side of the filter chamber 51 has a sliding groove 54 matching the fragrance component 521 to facilitate the disassembly and replacement of the fragrance component 521.

[0044] During operation, an aromatherapy mechanism 5 is installed on the side of the air intake chamber 41. Air entering the air intake chamber 41 is processed by this mechanism. The aromatherapy mechanism 5 includes a filter chamber 51 and multiple impellers 52 rotatably connected to its side. The filter chamber 51 contains an activated carbon mesh. The activated carbon mesh utilizes the adsorption properties of activated carbon to filter the air. Activated carbon has a large specific surface area, enabling it to adsorb impurities, harmful gases, and odors in the air. When air enters the filter chamber 51, it flows across the surface of the activated carbon mesh, and impurities, harmful gases, and odors are adsorbed by the activated carbon, thus... To achieve air filtration and purification, the impeller 52 includes a fragrance component 521, which is fixedly connected inside the impeller shaft 523. When air enters, it drives the impeller 52 to rotate. When the impeller shaft 523 rotates, it blows out the fragrance inside the fragrance component 521, so that the air entering the car has a pleasant fragrance and is also filtered and purified. The rotation of the impeller 52 is based on the power of air flow. When air enters the air intake chamber 41 and flows through the impeller 52, the air flow will generate a torque on the impeller 52, causing the impeller 52 to rotate around its axis.

[0045] As one embodiment of the present invention, such as Figure 7 and Figure 8As shown, the fragrance component 521 includes a fragrance rod 5211 disposed on one side of the fragrance component 521, and an elastic rod 5213 is movably connected to the inside of the fragrance rod 5211 via a latch 5212. A straight rod 524 is fixedly connected to the inside of one side of the fan shaft 523. An upper protruding ring 525 matching the elastic rod 5213 is fixedly connected to the front end of the straight rod 524, and a lower protruding ring 526 is also movably connected to the straight rod 524. The maximum radius of the lower protruding ring 526 is greater than the maximum radius of the upper protruding ring 525, so that when the fragrance rod 5211 is pushed, the upper protruding ring 525 is unlocked from the latch 5212 through the lower protruding ring 526.

[0046] During operation, the front end of the straight rod 524 is fixedly connected to an upper convex ring 525 that matches the elastic rod 5213. A lower convex ring 526 is also movably connected to the straight rod 524, and the maximum radius of the lower convex ring 526 is greater than the maximum radius of the upper convex ring 525. When the fragrance component 521 needs to be operated, such as changing the fragrance substance, pushing the fragrance rod 5211 will cause the elastic rod 5213 to move along with it. Due to the larger radius of the lower convex ring 526, when the fragrance rod 5211 moves to a certain extent, the elastic rod 5213 will contact the lower convex ring 526, and the fragrance rod... As 5211 continues to be pushed, the lower convex ring 526 applies an outward force to the elastic rod 5213, causing the elastic rod 5213 to overcome its engagement with the upper convex ring 525. This allows the lower convex ring 526 to unlock the upper convex ring 525 from the latch 5212, thus allowing the fragrance rod 5211 to be removed from the fragrance component 521. This enables maintenance or replacement of fragrance substances inside the fragrance component 521. After the operation is completed, the fragrance rod 5211 is reinserted, and the elastic rod 5213 will re-engage with the upper convex ring 525 under its own elasticity, thus re-fixing the fragrance component 521.

[0047] As one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 9 As shown, an auxiliary door opening mechanism 7 for assisting door opening is provided on the side of the gas storage chamber 31. The auxiliary door opening mechanism 7 includes two air chambers 71 opened inside the gas storage chamber 31, and an air pipe 72 is fixedly connected inside the air chamber 71. A one-way valve 73 for gas passage is provided inside the air pipe 72 so that the gas pressure difference drives the door to move initially. A sealing membrane 74 to prevent air leakage is fixedly connected to the end of the air pipe 72.

[0048] During operation, when the side sliding door is triggered (e.g., by an infrared sensor detecting that the side sliding door handle is pulled), the gas pre-stored in the gas storage chamber 31, under the control of the control system, begins to flow through the gas pipe 72 into the air chamber 71 of the auxiliary door opening mechanism 7. Due to the one-way valve 73 installed in the gas pipe 72, the gas can only flow in the direction from the gas storage chamber 31 to the air chamber 71, effectively preventing backflow and ensuring that the air chamber 71 can smoothly establish a high-pressure environment. As gas continuously flows into the air chamber 71, the air chamber 7... The pressure inside the door rises rapidly. Since the air chamber 71 is located in a specific position inside the sliding door (close to the edge of the door or associated with the door's load-bearing structure to facilitate the effective application of thrust), while other areas inside the vehicle are at a relatively normal or low pressure (the interior space is connected to the outside atmosphere, the air pressure is relatively stable, and there is a significant pressure difference with the air chamber 71), this pressure difference generates a strong thrust on both sides of the sliding door. This thrust acts directly on the sliding door, pushing it to move outward, thus achieving the initial pull-out action.

[0049] Working Principle: During operation, when the side sliding door 2 opens, the infrared sensor on its side quickly detects this movement. The infrared sensor detects the movement of objects based on the principle of infrared reflection or absorption. When the side sliding door 2 moves, it changes the propagation path of the surrounding infrared rays, thus being detected by the infrared sensor. After detecting that the door is open, the infrared sensor transmits an electrical signal to the air pump connected to it via a pre-set circuit connection. Upon receiving the signal, the air pump starts working. Through its own mechanical structure and working principle, it draws in and compresses external air, and then delivers the compressed air to the air storage chamber 31 through pipes or other connections. The air storage chamber 31 has multiple air inlets 32 equidistantly arranged on its side. The design of these air inlets 32... The design aims to ensure that air enters the gas storage chamber 31 evenly, guaranteeing a uniform gas pressure distribution within it. Gas enters the gas storage chamber 31 through these inlets 32, each equipped with a diaphragm valve 6. The diaphragm valve 6 operates based on the elastic deformation of a diaphragm. When gas enters, the gas pressure causes the diaphragm to deform and open the valve, allowing gas to enter the gas storage chamber 31. Once the gas pressure inside the gas storage chamber 31 reaches a certain level, the diaphragm, under the combined action of its own elasticity and the gas pressure within the chamber, gradually returns to a certain degree, placing the valve in a slow venting state. This ensures that the gas pressure inside the gas storage chamber 31 does not become excessively high, while also allowing for the slow release of gas when needed. As gas continuously fills the gas storage chamber 31... As the internal pressure gradually increases, a top plate 33 is fixedly connected to the gas storage chamber 31 via multiple equidistantly arranged elastic mechanisms 34 (such as springs, spiral telescopic tubes, or gas struts). The function of the elastic mechanisms 34 is to provide support and restoring force to the top plate 33 when the gas pressure changes. When the gas pressure increases to a certain level, the gas will push up the top plate 33. Nut sleeves 35 are fixedly connected to both ends of the top plate 33. During the process of the top plate 33 being pushed up, the nut sleeves 35 will move on the threaded rod 36. Since the nut sleeves 35 and the threaded rod 36 are connected by a ball nut pair, which is a high-precision transmission mechanism that converts rotary motion into linear motion, when the nut sleeves 35 move up and down, the balls will roll between the threads of the nut sleeves 35 and the threaded rod 36. This causes the threaded rod 36 to rotate, which in turn drives the rotating rod 45 in the intake mechanism 4 to rotate. Three baffles 42 are rotatably connected inside the intake chamber 41 of the intake mechanism 4. Turbines 43 are fixedly connected to both ends of each baffle 42. Three worm gears 46, matching the turbines 43, are fixedly connected to the rotating rod 45. When the rotating rod 45 rotates, the meshing transmission between the worm gears 46 and the turbines 43 drives the turbines 43 to rotate. This meshing transmission is based on the gear transmission principle; the worm gear 46 acts like a screw, and the turbine 43 acts like a gear. When the worm gears 46 rotate, they push the turbines 43 to rotate. A rotating shaft 44 is also fixedly connected to both ends of the turbine 43. During the rotation of the turbine 43, the rotating shaft 44 causes the baffles 42 to unfold.This allows outside air to enter the air intake chamber 41 when the car is not in use for extended periods. The baffle 42 unfolds by rotating the shaft 44, causing the baffle 42 to rotate around its connection point with the air intake chamber 41, thus opening the air intake passage. An aromatherapy mechanism 5 is located on the side of the air intake chamber 41. The air entering the air intake chamber 41 is processed by the aromatherapy mechanism 5. The aromatherapy mechanism 5 includes a filter chamber 51 and multiple impellers 52 rotatably connected to its side. The filter chamber 51 contains an activated carbon mesh, which utilizes the adsorption properties of activated carbon to filter the air. Activated carbon has a large specific surface area and can adsorb impurities and harmful gases in the air. The air filter 52 removes impurities and odors. When air enters the filter chamber 51, it flows over the surface of the activated carbon mesh. Impurities, harmful gases, and odors are adsorbed by the activated carbon, thus filtration and purification of the air. The impeller 52 includes a fragrance component 521, which is fixedly connected inside the impeller shaft 523. When air enters, it drives the impeller 52 to rotate. As the impeller shaft 523 rotates, it blows out the fragrance from inside the fragrance component 521, making the air entering the vehicle pleasantly scented and also filtered and purified. The rotation of the impeller 52 is based on the power of airflow. When air enters the intake chamber 41 and flows through the impeller 52, the air... The airflow generates a torque on the impeller 52, causing it to rotate around its axis. The front end of the straight rod 524 is fixedly connected to an upper convex ring 525 that matches the elastic rod 5213. A lower convex ring 526 is also movably connected to the straight rod 524, and the maximum radius of the lower convex ring 526 is larger than the maximum radius of the upper convex ring 525. When the fragrance component 521 needs to be operated, such as changing the fragrance substance, pushing the fragrance rod 5211 will cause the elastic rod 5213 to move as well. Due to the larger radius of the lower convex ring 526, when the fragrance rod 5211 moves to a certain extent, the elastic rod 5213 will contact the lower convex ring 5213. As the fragrance rod 5211 continues to be pushed, the lower protruding ring 526 applies an outward force to the elastic rod 5213, causing the elastic rod 5213 to overcome its engagement with the upper protruding ring 525. This unlocks the upper protruding ring 525 from the latch 5212, allowing the fragrance rod 5211 to be removed from the fragrance assembly 521. This facilitates maintenance or replacement of fragrance substances within the fragrance assembly 521. After these operations are completed, the fragrance rod 5211 is reinserted, and the elastic rod 5213, under its own elasticity, re-engages with the upper protruding ring 525, thus re-secureing the fragrance assembly 521.
