Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive seat ventilation bag technology, specifically an air bag for automotive seat ventilation systems. Background Technology
[0002] In the modern automotive industry, as people's demands for driving and riding comfort continue to increase, car seat ventilation systems have gradually become standard equipment in mid-to-high-end models. Car seat ventilation systems deliver air to the seat surface, removing heat and moisture from the parts of the body that come into contact with the seat, effectively avoiding problems such as stuffiness and dampness caused by long-term sitting, and improving the driving and riding experience.
[0003] As a key component of automotive seat ventilation systems, the performance of the air bag directly affects the overall effectiveness of the system. Existing air bags used in automotive seat ventilation systems have many problems in actual use. Among them, the most prominent is the lack of air filtration. Most air bags on the market are not equipped with a dedicated filtration device, allowing dust, hair, pollen, and other impurities from the outside air to directly enter the air bag. This not only easily clogs the air bag's vents, affecting ventilation, but also accumulates a large amount of dirt inside the air bag, breeding bacteria and producing odors, posing a potential threat to the health of drivers and passengers.
[0004] According to the description in the patent announcement (CN218430961U) for an air bag for a car seat ventilation system published on the patent website, the air bag for the car seat ventilation system includes "airtight non-woven fabric, air inlet" etc., to achieve ventilation.
[0005] Regarding the above description, the applicant believes the following issues exist:
[0006] The air bag used in this car seat ventilation system utilizes airtight non-woven fabric and air inlets to achieve ventilation. However, this air bag is only designed to achieve ventilation, and it lacks a structure to filter the air during the ventilation process. This allows impurities such as dust, hair, and pollen from the outside air to directly enter the air bag, which can easily clog the air outlets, affecting the ventilation effect and posing a potential threat to the health of drivers and passengers. Therefore, this air bag needs to be improved. Utility Model Content
[0007] The purpose of this invention is to provide an air bag for a car seat ventilation system to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention provides the following technical solution: an air bag for a car seat ventilation system, comprising an air bag body, a ventilation mechanism at the bottom of the air bag body, and a fixing mechanism at the bottom of the ventilation mechanism;
[0009] The ventilation mechanism includes a fixed plate disposed within the air bag body. A connecting shaft is threadedly connected to the inside of the fixed plate. A mounting frame is slidably connected to the periphery of the connecting shaft. The mounting frame is disposed at the bottom of the air bag body. A nut is threadedly connected to the periphery of the connecting shaft. A fixed frame is fixedly connected to the bottom of the mounting frame. A filter plate is slidably connected inside the fixed frame. A mounting bracket is fixedly connected to the inner side of the mounting frame. A servo motor is fixedly connected to the bottom of the mounting bracket. A rotating shaft is fixedly connected to the top of the servo motor. Fan blades are fixedly connected to the periphery of the rotating shaft.
[0010] Preferably, the bottom of the fixing plate is in contact with the bottom of the air bag body, and the top of the mounting frame is in contact with the bottom of the air bag body, so as to ensure the stable operation of the fan blades under the action of the mounting frame.
[0011] Preferably, the fixed frame has a sliding groove inside, the filter plate is slidably connected in the sliding groove, and the mounting frame has a wiring groove inside, and the wiring groove is circular, so as to ensure the stability of the filter plate through the sliding groove.
[0012] Preferably, the rotating shaft is rotatably connected inside the mounting frame, and the connecting shaft passes through the inside of the air bag body, so as to facilitate the operation of the fan blades by rotating the shaft.
[0013] Preferably, the fixing mechanism includes a sealing cover, which is threaded to the bottom of the fixing frame. A telescopic rod is fixedly connected to the bottom of the sealing cover, a protective frame is fixedly connected to the top of the telescopic rod, and a squeezing ball is fixedly connected to the top of the protective frame. The squeezing ball is located at the bottom of the filter plate, and a spring is sleeved around the telescopic rod.
[0014] Preferably, the top of the spring is fixedly connected to the top of the protective frame, and the bottom of the spring is fixedly connected to the bottom of the sealing cover, so that the spring can buffer the telescopic rod under the action of the spring, thereby avoiding damage to the filter plate caused by squeezing the ball.
[0015] Preferably, the outer periphery of the extrusion ball is in contact with the bottom of the filter plate, the bottom of the fixing frame is provided with a fixing groove, and the sealing cap is threaded into the fixing groove to facilitate sealing the bottom of the fixing frame through the sealing cap.
[0016] Compared with the prior art, the present invention provides an air bag for a car seat ventilation system, which has the following beneficial effects:
[0017] 1. This car seat ventilation system uses an air bag. Through a set ventilation mechanism, the fixing plate and mounting frame are in close contact with the bottom of the air bag body, respectively. With the threaded connection of the connecting shaft and nut, a stable installation structure is formed, ensuring the stability between the fixing plate, mounting frame and air bag body. This completes the fixation of the mounting frame. At the same time, the connection cable of the servo motor is connected to the power supply equipment near the car seat through the wiring groove for power supply. The outer protruding part of the filter plate is in a horizontal position. It slides upward in the fixing frame first. When it slides to the bottom, it rotates 90 degrees to initially install the filter plate. The servo motor drives the rotating shaft and fan blades to continuously provide a stable and strong airflow to the air bag body, improving the ventilation efficiency of the car seat and creating a comfortable environment for the driver and passengers. The filter plate can effectively intercept dust and impurities in the air, preventing them from entering the air bag body and affecting the ventilation effect or causing pollution inside the car seat. The filter plate can be easily removed and replaced by pulling it out along the sliding groove in the fixing frame.
[0018] 2. The air bag used in this automotive seat ventilation system, through a fixed mechanism, ensures that when the mounting frame and air bag body are installed under the action of the connecting shaft, and the filter plate is slidably connected inside the fixed frame, the sealing cover is threaded to the bottom of the fixed frame. This not only provides sealing protection for the filter plate but also facilitates opening the sealing cover for maintenance. During the tightening of the sealing cover, the compression ball contacts the filter plate and compresses the telescopic rod and spring, causing them to extend and deform. After the sealing cover is fixed, the telescopic rod and spring ensure that the outer periphery of the compression ball remains in contact with the bottom of the filter plate, guaranteeing its stability and preventing displacement of the filter plate during air bag operation. The elasticity of the spring also provides a certain buffering and shock absorption effect, preventing excessive compression of the filter plate and extending its service life.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] This utility model provides the following technical solution: Example 1
[0031] Please see Figure 1-7 This utility model provides a technical solution: an air bag for a car seat ventilation system, including an air bag body 1, a ventilation mechanism 2 at the bottom of the air bag body 1, and a fixing mechanism 3 at the bottom of the ventilation mechanism 2;
[0032] The ventilation mechanism 2 includes a fixed plate 21, which is disposed inside the air bag body 1. A connecting shaft 22 is threadedly connected inside the fixed plate 21. A mounting frame 23 is slidably connected to the outer periphery of the connecting shaft 22. The mounting frame 23 is disposed at the bottom of the air bag body 1. A nut 24 is threadedly connected to the outer periphery of the connecting shaft 22. A fixed frame 25 is fixedly connected to the bottom of the mounting frame 23. A filter plate 26 is slidably connected inside the fixed frame 25. A mounting bracket 27 is fixedly connected to the inner side of the mounting frame 23. A servo motor 28 is fixedly connected to the bottom of the mounting bracket 27. A rotating shaft 291 is fixedly connected to the top of the servo motor 28. A fan blade 29 is fixedly connected to the outer periphery of the rotating shaft 291.
[0033] The bottom of the fixing plate 21 is in contact with the bottom of the air bag body 1, and the top of the mounting frame 23 is in contact with the bottom of the air bag body 1, so as to ensure the stable operation of the fan blade 29 under the action of the mounting frame 23.
[0034] The fixed frame 25 has a sliding groove inside, and the filter plate 26 is slidably connected in the sliding groove. The mounting frame 23 has a wiring groove inside, and the wiring groove is circular, which facilitates the stability of the filter plate 26 through the sliding groove. The rotating shaft 291 is rotatably connected inside the mounting bracket 27, and the connecting shaft 22 passes through the inside of the air bag body 1, which facilitates the operation of the fan blade 29 through the rotating shaft 291. Example 2
[0035] Please see Figure 1-7 Furthermore, based on Embodiment 1, the fixing mechanism 3 includes a sealing cover 31, which is threaded to the bottom of the fixing frame 25. A telescopic rod 32 is fixedly connected to the bottom of the sealing cover 31, and a protective frame 34 is fixedly connected to the top of the telescopic rod 32. A compression ball 35 is fixedly connected to the top of the protective frame 34, and the compression ball 35 is located at the bottom of the filter plate 26. A spring 33 is sleeved around the telescopic rod 32.
[0036] The top of the spring 33 is fixedly connected to the top of the protective frame 34, and the bottom of the spring 33 is fixedly connected to the bottom of the sealing cover 31. This facilitates the buffering effect of the telescopic rod 32 under the action of the spring 33, thereby preventing the filter plate 26 from being damaged by the squeeze ball 35. The outer periphery of the squeeze ball 35 is in contact with the bottom of the filter plate 26. The bottom of the fixed frame 25 is provided with a fixing groove, and the sealing cover 31 is threaded into the fixing groove, which facilitates sealing the bottom of the fixed frame 25 through the sealing cover 31.
[0037] In actual operation, when this device is used, first adjust the position of the fixing plate 21 inside the air bag body 1 so that the fixing plate 21 and the mounting frame 23 are in close contact with the bottom and bottom of the air bag body 1 respectively, and are consistent. At this time, slide the connecting shaft 22 inside the mounting frame 23 and pass through the air bag body 1, and thread it inside the fixing plate 21. At the same time, thread the nut 24 to the outside of the connecting shaft 22 to ensure the stability between the fixing plate 21, the mounting frame 23 and the air bag body 1. At the same time, connect the servo motor 28 to the power supply equipment near the car seat through the wiring slot to supply power.
[0038] After connection, make the protruding part of the filter plate 26 horizontal and slide it upward in the fixed frame 25. When it slides to the bottom, rotate it 90 degrees to initially install the filter plate 26. At this time, make the sealing cover 31 threaded to the bottom of the fixed frame 25. This not only seals and protects the filter plate 26, but also makes it easy to open the sealing cover 31 to maintain the filter plate 26. During the tightening of the sealing cover 31, the extrusion ball 35 will contact the filter plate 26 and compress the telescopic rod 32 and the spring 33, causing them to move and deform. After the sealing cover 31 is fixed, the telescopic rod 32 and the spring 33 can ensure that the outer edge of the extrusion ball 35 is always in contact with the bottom of the filter plate 26, ensuring its stability and ensuring that the filter plate 26 will not be displaced during the operation of the air bag. The elasticity of the spring 33 can also play a certain role in buffering and shock absorption, avoiding excessive compression of the filter plate 26 and extending the service life of the filter plate 26.
[0039] After installation and protection are completed, the air bag body 1 can be fixed inside the car seat by external fixing equipment. The servo motor 28 drives the rotating shaft 291 and fan blades 29 to continuously provide a stable and strong airflow to the air bag body 1, improve the ventilation efficiency of the car seat, and create a comfortable environment for the driver and passengers. The filter plate 26 can effectively intercept dust, impurities and other particles in the air to prevent them from entering the air bag body 1 and affecting the ventilation effect or causing pollution to the inside of the car seat.
[0040] When the filter plate 26 needs to be cleaned or replaced, simply remove the sealing cover 31 and take out the filter plate 26.
[0041] The use of the air bag body 1, the installation of the air bag body 1 in the car seat, and the wiring and power supply of the servo motor 28 are all basic skills required by those skilled in the art. Those skilled in the art can skillfully operate these skills to perform installation and wiring work, and will not be described in detail in this case.
