Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to a seat ventilation fan shock absorption and anti-pressure mechanism. Background Technology

[0002] Seat ventilation fans are typically installed on the foam back of the seat cushion and backrest. When in operation, the fan draws in air, directs it into the ventilation layer, and the airflow then permeates upwards from the surface of the ventilation layer, passing through the heating pad and flowing to the surface of the seat cover. Since the seat cover is usually made of perforated leather, air flows out through these small holes, achieving the ventilation function and effectively improving the air circulation environment of the part of the body in contact with the seat surface. The seat ventilation fan shock absorption and anti-pressure mechanism is an important component to ensure the stable operation of the seat ventilation fan and improve riding comfort. It usually uses pressure-resistant materials or shock absorption mechanisms to achieve shock absorption.

[0003] While existing shock absorption mechanisms offer numerous advantages during use, they still suffer from the following problems: poor uniformity of pressure distribution; and the fact that the pressure distribution on the fan depends on the seating posture of the person in the seat, which can lead to a shift in the pressure angle of the fan, causing pressure points to accumulate and potentially damaging the fan. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a seat ventilation fan shock absorption and anti-pressure mechanism.

[0005] The technical solution adopted by this utility model to solve its technical problem is a seat ventilation fan shock absorption and anti-pressure mechanism, including a fixed plate, a fixed block and a movable rod. The fixed plate is provided with an exhaust hood inside. The upper outer wall of both the fixed plate and the exhaust hood is equipped with a circular array of fixed blocks. A bearing is embedded in one side of the upper outer wall of the fixed block. A support plate is interference-fitted to the upper end of the bearing. A sleeve is provided on the upper outer wall of the support plate. The movable rod and the sleeve are rotatably installed inside the sleeve.

[0006] By adopting the above technical solution, the circular array of movable rods and sleeves can make the exhaust hood uniformly stressed in all directions inside the fixed plate, enhancing the stability of the overall structure. The bearings allow the support plate to rotate flexibly, thereby enabling the exhaust hood to move relative to the fixed block. This ensures that the fan body can shift at an angle after being pressed, ensuring that the fan body is uniformly stressed, reducing pressure point concentration, and minimizing damage to the fan body.

[0007] Specifically, the outer wall of the fixing plate is equipped with a circular array of connectors, and the interior of the fixing plate adopts a through-type design.

[0008] By adopting the above technical solution, the fixing plate can be connected to the matching bracket of the seat through the connector, ensuring the stability of the fixing plate in use, and the through-type design provides a range of motion for the exhaust hood.

[0009] Specifically, the exhaust hood has ventilation holes inside, a fan body is installed on one side of the inner wall of the ventilation holes, and sealing gaskets are glued and fixed to the upper and lower outer walls of the exhaust hood.

[0010] By adopting the above technical solution, the fan body can effectively exhaust air through the ventilation holes to realize the function of seat ventilation. The sealing gasket can prevent air leakage, improve ventilation efficiency, and at the same time reduce the noise generated by the fan body when it is working and improve the user experience.

[0011] Specifically, fasteners are installed on both sides of the support plate and the outer wall of the sleeve. Bolts are provided inside the fasteners, and the fasteners are connected to each other by bolts.

[0012] By adopting the above technical solution, fasteners and bolts can ensure a tight connection between the support plate and the ferrule, preventing loosening during use, ensuring the stability of the entire shock absorption and anti-pressure mechanism, and facilitating the disassembly and maintenance of the ferrule, thereby improving the adjustability and maintainability of the equipment.

[0013] Specifically, the size of the movable rod is smaller than the inner wall size of the sleeve, and the movable rod is located inside the sleeve.

[0014] By adopting the above technical solution, the movable rod can freely extend and retract within the sleeve, providing a foundation for the realization of the shock absorption function. When subjected to pressure, the movable rod can slide within the sleeve, absorbing and dispersing the pressure, thus playing a role in shock absorption.

[0015] Specifically, a spring is provided on one side of the inner wall of the sleeve, and the movable rod is elastically connected to the inner wall of the sleeve through the spring.

[0016] By adopting the above technical solution, the spring has the characteristic of elastic deformation. When the moving rod is subjected to pressure, the spring will be compressed, converting the pressure into the elastic potential energy of the spring, thereby effectively buffering and absorbing the pressure, and further improving the shock absorption performance.

[0017] Specifically, a cover plate is provided on the outside of the sleeve, and the cover plate is located outside the movable rod. Both the cover plate and the outer wall of the sleeve are equipped with support members distributed in a circular array, and the cover plate and the sleeve are connected by screws of the support members.

[0018] By adopting the above technical solution, the cover plate can shield the sleeve, and the movable rod can move inside the cover plate. Thus, the cover plate can limit the movement distance of the movable rod, ensuring the structural stability of the exhaust hood, and the support component ensures the stability of the connection between the cover plate and the sleeve.

[0019] The beneficial effects of this utility model are:

[0020] (1) The seat ventilation fan shock absorption and anti-pressure mechanism of this utility model allows the exhaust cover to be displaced relative to the fixed block, ensuring that the fan body can be deflected at an angle after being pressed, ensuring that the fan body can be evenly stressed, reducing the concentration of pressure points, and reducing the damage to the fan body.

[0021] (2) The seat ventilation fan shock absorption and anti-pressure mechanism of this utility model has a spring that is compressed when the movable rod is subjected to pressure, which converts the pressure into the elastic potential energy of the spring, thereby effectively buffering and absorbing the pressure and ensuring the shock absorption performance.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the seat ventilation fan shock absorption and anti-pressure mechanism of this utility model includes a fixed plate 1, a fixed block 2 and a movable rod 3. An exhaust hood 12 is provided inside the fixed plate 1. Fixed blocks 2 are arranged in a circular array on the upper outer wall of both the fixed plate 1 and the exhaust hood 12. A bearing 21 is embedded in one side of the upper outer wall of the fixed block 2. A support plate 22 is interference-fitted to the upper end of the bearing 21. A sleeve 24 is provided on the upper outer wall of the support plate 22. The movable rod 3 and the sleeve 31 are rotatably installed inside the sleeve 24.

[0030] In use, the circular array of movable rods 3 and sleeves 31 ensures that the exhaust hood 12 is subjected to uniform force in all directions inside the fixed plate 1, enhancing the stability of the overall structure. The bearing 21 allows the support plate 22 to rotate flexibly, thereby enabling the exhaust hood 12 to move relative to the fixed block 2. This ensures that the fan body 14 can deflect at an angle after being pressed, ensuring that the fan body 14 is subjected to uniform force, reducing pressure point concentration, and reducing damage to the fan body 14.

[0031] To fix the usage location, for example, such as Figure 1 As shown, the outer wall of the fixing plate 1 is equipped with a circular array of connectors 11, and the interior of the fixing plate 1 adopts a through-type design.

[0032] When in use, the fixing plate 1 can be connected to the matching bracket of the seat through the connector 11 to ensure the stability of the fixing plate 1 in use, and the through design provides the exhaust hood 12 with a range of motion.

[0033] For ventilation, for example, such as Figure 1 As shown, the exhaust hood 12 has ventilation holes 13 inside, and a fan body 14 is installed on one side of the inner wall of the ventilation hole 13. Sealing gaskets 15 are glued and fixed to the upper and lower outer walls of the exhaust hood 12.

[0034] When in use, the fan body 14 can effectively exhaust air through the ventilation hole 13 to realize the function of seat ventilation. The sealing gasket 15 can prevent air leakage, improve ventilation efficiency, and at the same time reduce the noise generated by the fan body 14 when it is working and improve the user experience.

[0035] For securing the connection, for example, such as Figure 3 As shown, fasteners 23 are installed on both outer walls of the support plate 22 and the sleeve 24. Bolts 25 are provided inside the fasteners 23, and the fasteners 23 are connected to each other by bolts 25.

[0036] During use, the fasteners 23 and bolts 25 ensure a tight connection between the support plate 22 and the ferrule 24, preventing loosening during use, ensuring the stability of the entire shock absorption and anti-pressure mechanism, and facilitating the disassembly and maintenance of the ferrule 24, thereby improving the adjustability and maintainability of the equipment.

[0037] To provide space for movement, for example, such as Figure 4 As shown, the size of the movable rod 3 is smaller than the inner wall size of the sleeve 31, and the movable rod 3 is located inside the sleeve 31.

[0038] During use, the movable rod 3 can freely extend and retract within the sleeve 31, providing a basis for the realization of the shock absorption function. When subjected to pressure, the movable rod 3 can slide within the sleeve 31 to absorb and disperse the pressure, thus playing a role in shock absorption.

[0039] For shock absorption, for example, such as Figure 4 As shown, a spring 32 is provided on one side of the inner wall of the sleeve 31, and the movable rod 3 is elastically connected to the inner wall of the sleeve 31 through the spring 32.

[0040] When in use, the spring 32 has the characteristic of elastic deformation. When the movable rod 3 is subjected to pressure, the spring 32 will be compressed, converting the pressure into the elastic potential energy of the spring 32, thereby effectively buffering and absorbing the pressure, and further improving the shock absorption performance.

[0041] To limit the distance of movement, for example, such as Figure 4 As shown, a cover plate 33 is provided on the outside of the sleeve 31, and the cover plate 33 is located outside the movable rod 3. Both the cover plate 33 and the outer wall of the sleeve 31 are equipped with support members 34 arranged in a circular array, and the cover plate 33 and the sleeve 31 are connected by screws through the support members 34.

[0042] In use, the cover plate 33 can cover the sleeve 31, and the movable rod 3 can move inside the cover plate 33. Thus, the cover plate 33 can limit the movement distance of the movable rod 3, ensuring the structural stability of the exhaust hood 12, and the support member 34 ensures the stability of the connection between the cover plate 33 and the sleeve 31.

[0043] When this utility model is in use, after the fan body 14 is started, it effectively discharges air through the ventilation hole 13 to realize the function of seat ventilation. When the seat is under pressure, the pressure is transmitted to the exhaust hood 12. Due to the circular array distribution of the movable rods 3 and the sleeves 31, the exhaust hood 12 is subjected to uniform force in all directions inside the fixed plate 1. The movable rods 3 can freely extend and retract inside the sleeves 31. When under pressure, the movable rods 3 slide inside the sleeves 31 to absorb and disperse the pressure. At the same time, the springs 32 on the inner wall of the sleeves 31 are compressed, converting the pressure into the elastic potential energy of the springs 32, further buffering and absorbing the pressure, and playing a good shock absorption role.

[0044] The bearing 21 allows the support plate 22 to rotate flexibly, thereby allowing the exhaust shroud 12 to be displaced relative to the fixed block 2. When the fan body 14 is under pressure, it can undergo angular displacement, ensuring that the fan body 14 is evenly stressed and reducing pressure point concentration.
