[0023] The following is for reference. Figures 1-8 The present invention describes a seat ventilation assembly 100 according to an embodiment of the present invention. The seat ventilation assembly 100 can achieve efficient ventilation function, improve ventilation efficiency, reduce the number of parts, effectively ensure ventilation volume, improve user experience, has a simple overall structure, high process feasibility, low manufacturing cost, is easy to manufacture, and has a high degree of integration.

[0024] like Figures 1-8 As shown, a seat ventilation assembly 100 according to an embodiment of the present invention includes: a seat cushion body 1 and a ventilation structure 2.

[0025] First, it should be noted that the seat ventilation assembly 100 of this utility model can be either a blowing type or a suction type. The following description will take the suction type seat ventilation assembly 100 as an example.

[0026] The seat cushion body 1 is the structural component that passengers sit on directly, bearing the weight of the passengers. It has good softness and elasticity and is relatively thick, which plays a role in supporting the human body. Thus, the seat cushion body 1 can improve the comfort of passengers and protect the original seat. The seat can be equipped with a ventilation structure, namely the seat ventilation assembly 100, to cool the seat surface and remove heat and moisture from the seat surface.

[0027] The seat cushion body 1 has multiple ventilation holes 11, meaning that the seat cushion body 1 can have two, three, four, or even more ventilation holes 11. The ventilation holes 11 are arranged along the thickness direction of the seat cushion body 1, i.e., in the vertical direction, so that hot air from the seat surface can flow from the upper surface of the seat cushion body 1 to the lower surface of the seat cushion body 1 through the ventilation holes 11. By setting multiple ventilation holes 11, hot air from the seat surface can flow downward through multiple ventilation holes 11 simultaneously, thereby improving ventilation efficiency and quickly cooling the seat surface.

[0028] The ventilation structure 2 is used to achieve ventilation, allowing hot air flowing to the lower surface of the seat cushion body 1 to further flow downward through the ventilation structure 2 and then be discharged downward. The ventilation structure 2 is located at the bottom of the seat cushion body 1 so that it can receive hot air flowing to the lower surface of the seat cushion body 1. The ventilation structure 2 is provided with an air guide trough 21 and an air intake 22. The air guide trough 21 is connected to multiple ventilation holes 11 and is used to connect the multiple ventilation holes 11 to the air intake 22. That is, the air guide trough 21 is connected to both the multiple ventilation holes 11 and the air intake 22. One side of the air guide trough 21 is connected to the multiple ventilation holes 11, and the other side of the air guide trough 21 is connected to the air intake 22. Thus, the hot air flowing downward to the lower surface of the seat cushion body 1 through the multiple ventilation holes 11 can enter the air guide trough 21 and flow within it. Then, it is guided by the air guide trough 21 to the air intake 22 and discharged downward, realizing the ventilation function of the entire seat ventilation assembly 100.

[0029] Thus, multiple ventilation holes 11, air guide slots 21 and air intakes 22 together form an air guide channel, enabling hot air to flow smoothly from top to bottom, thereby achieving efficient ventilation.

[0030] In practical design, the seat cushion body 1 can be manufactured using materials such as polyurethane through foaming, resulting in a porous internal structure with good softness and elasticity, thus providing excellent comfort and support. The foaming process with polyurethane and other materials primarily optimizes the seat's indentation depth, hysteresis loss rate, damping coefficient, and elasticity coefficient by adjusting the foam thickness and hardness, thereby improving seating comfort. During actual manufacturing, polyurethane and a fixative are mixed in a certain proportion to form a foaming mixture, which is then injected into a foaming mold. After treatment and curing, the ventilation holes 11 on the seat cushion body 1 are also integrally formed by the mold. After foaming and curing, the ventilation holes 11 also solidify, thus realizing the manufacturing of the seat cushion body 1. Therefore, the ventilation holes 11 are formed on the seat cushion body 1, meaning they are integrated into the seat cushion body 1, making manufacturing simple and convenient.

[0031] Furthermore, the ventilation structure component 2 can be made of foamed polypropylene material. Foamed polypropylene material (EPP) uses PP as the main raw material and adopts physical foaming technology to make foamed beads. That is, the ventilation structure component 2 is rigid EPP, which can ensure the rigidity of the ventilation structure component 2, so that the seat ventilation assembly 100 can effectively support the weight of the human body, effectively improve its load-bearing capacity, and prevent the air guide duct 21 from being deformed or damaged, thus affecting the ventilation function. The air guide duct 21 can be integrally formed with the ventilation structure component 2 through a mold. That is, while forming the ventilation structure component 2, the air guide duct 21 is also formed on the ventilation structure component 2. It is convenient to manufacture and has high manufacturing efficiency. Moreover, since EPP has excellent cushioning performance and toughness, the grooving on the ventilation structure component 2 will not affect its structural performance.

[0032] It should be noted that in existing technologies, ventilation bladders are installed at the bottom of the seat foam, connecting the bladders to the foam to form an airflow channel. A fan connects to the bladders to achieve ventilation. This method is complex, involves many components, has low ventilation efficiency, and is difficult to implement. Furthermore, under high load, the bladders are compressed, reducing the airflow channel and decreasing the air volume, thus affecting passenger comfort. In contrast, this application integrates a ventilation structure 2 with an air guide trough 21 and an air intake 22. The air guide trough 21 connects multiple ventilation holes 11 and air intakes 22, achieving highly efficient ventilation, improving efficiency, reducing the number of components, and ensuring strong load-bearing capacity even under high load. This enhances user experience. The overall structure is simple, has high feasibility, low manufacturing cost, is easy to manufacture, highly integrated, and lightweight.

[0033] According to the embodiment of the present utility model, the seat ventilation assembly 100 has multiple ventilation holes 11 formed in the seat cushion body 1, and air guide grooves 21 and air inlets 22 are provided in the ventilation structure 2. The air guide grooves 21 are respectively connected to the multiple ventilation holes 11 and are used to connect the multiple ventilation holes 11 to the air inlets 22. Thus, the multiple ventilation holes 11, air guide grooves 21 and air inlets 22 together form an air guide channel, realizing efficient ventilation function, eliminating the ventilation transfer link, improving ventilation efficiency, reducing the number of parts, and the ventilation structure 2 has a strong load-bearing capacity. Even when the load is large, it can effectively ensure the ventilation volume, improve the user experience, and the overall structure is simple, has high process feasibility, low manufacturing cost, is easy to manufacture, has high integration, and is lightweight.

[0034] In some embodiments, the seat ventilation assembly 100 further includes a suction fan 3, which is used to draw air from the air inlet 22 and to discharge the airflow at the air guide slot 21 from the air inlet 22.

[0035] Specifically, when the blades of the suction fan 3 rotate at high speed, they will generate suction at the air intake 22. The suction will draw the hot air from the air guide 21 into the air intake 22, which will then flow to the bottom of the suction fan 3, i.e., the bottom of the ventilation structure 2, and then be discharged from the bottom, thereby achieving the discharge of hot air from the seat surface and achieving cooling.

[0036] Among them, by setting up a suction fan 3 to drive airflow circulation, the heat exchange between the seat and the air is accelerated, continuous ventilation is provided to avoid heat accumulation and improve heat dissipation efficiency. Moreover, the airflow is gentle, which can provide users with a comfortable riding experience and avoid the discomfort caused by direct airflow.

[0037] Therefore, the overall ventilation function is achieved through multiple ventilation holes 11, air guide channels 21, air intake 22 and air intake fan 3, without the need for other structural components and without ventilation transfer links. The entire seat ventilation assembly 100 has a simplified and efficient structure, lower cost, and more obvious cost reduction and efficiency improvement. In some embodiments, the ventilation structure 2 further forms a mounting groove 23, the air intake 22 is connected between the air guide groove 21 and the mounting groove 23, and the air intake fan 3 is installed in the mounting groove 23 and is distributed opposite to the air intake 22.

[0038] Specifically, the mounting slot 23 is used to install the suction fan 3, and the suction port 22 is connected between the air guide slot 21 and the mounting slot 23. That is, one end of the suction port 22 is connected to the air guide slot 21, and the other end of the suction port 22 is connected to the mounting slot 23. This allows the suction port 22 to be connected between the air guide slot 21 and the mounting slot 23, so that the hot air at the air guide slot 21 can flow to the suction port 22, and then flow into the mounting slot 23, and be discharged from the suction fan 3. Specifically, the size of the mounting slot 23 can be set to be larger than the structural size of the suction fan 3, so that there is a certain gap between the suction fan 3 and the inner wall of the mounting slot 23. This allows the suction fan 3 to be smoothly installed in the mounting slot 23, achieving a fixed installation of the suction fan 3, ensuring stable operation of the suction fan 3, preventing collision with the inner wall of the mounting slot 23, and thus preventing abnormal noise. At the same time, during vehicle operation, the seat will vibrate due to bumps, which can also prevent the suction fan 3 from tilting and hitting the inner wall of the mounting slot 23. Furthermore, it allows hot air to be discharged downwards through the gap between the suction fan 3 and the inner wall of the mounting slot 23, further improving ventilation efficiency.

[0039] In actual design, the suction fan 3 can be installed in the mounting slot 23 by screwing, snapping, hanging, gluing, etc., to ensure the installation stability of the suction fan 3. The detachable installation method such as screwing makes it easy to disassemble the suction fan 3 and facilitates maintenance and replacement.

[0040] The suction fan 3 and the air inlet 22 are positioned opposite each other, that is, the suction fan 3 and the air inlet 22 are coaxially distributed with their axes coinciding, forming a straight airflow channel. This facilitates the suction fan 3 inhaling hot air from the air guide groove 21 through the air inlet 22. In other words, the hot air in the air guide groove 21 is all gathered at the air inlet 22, enters the suction fan 3 in a straight line from the air inlet 22, and is then discharged downwards, thereby improving ventilation efficiency and reducing wind resistance and ventilation noise. In actual design, the air inlet 22 can be set to a circular, elliptical, or other flexible shapes, and can be flexibly selected according to the actual situation, not limited to the embodiment described herein.

[0041] In a specific embodiment, such as Figure 1 As shown, the bottom of the ventilation structure 2 is recessed to form a mounting groove 23. The suction fan 3 is installed in the mounting groove 23. The air intake 22 and the air guide 21 are provided on the ventilation structure 2. The upper end of the air intake 22 is connected to the air guide 21, and the lower end of the air intake 22 is connected to the mounting groove 23. Thus, the air intake 22 is connected between the air guide 21 and the mounting groove 23. The suction fan 3 is fixedly installed in the mounting groove 23 and is distributed directly opposite the air intake 22.

[0042] In some embodiments, such as Figure 1 and Figure 3 As shown, the air guide slot 21 is formed on the top of the ventilation structure 2 and opens upwards.

[0043] This allows the air guide slot 21 to open towards the bottom of the seat cushion body 1, so that the hot air on the seat surface can flow directly to the air guide slot 21 through the ventilation hole 11, thus ensuring that the airflow flows in a straight line in the vertical direction and ensuring efficient airflow.

[0044] Multiple ventilation holes 11 can be distributed directly opposite the air guide trough 21, so that the airflow in the multiple ventilation holes 11 can flow straight down into the air guide trough 21, thereby improving the airflow efficiency and thus improving the ventilation efficiency.

[0045] It should be noted that the shape of the ventilation hole 11 is not limited and can be set to any shape, such as circle, square, oval, etc.

[0046] In addition, the air ducts 21 can be distributed in the scenic area where passengers sit, that is, the core space area actually used by passengers, to improve the user's ventilation experience and make the passenger ride more comfortable.

[0047] In other embodiments, such as Figure 1 As shown, the bottom of the ventilation structure 2 is recessed to form a mounting groove 23, that is, the mounting groove 23 is formed at the bottom of the ventilation structure 2 and the mounting groove 23 is open downwards. This facilitates the installation of the suction fan 3 from bottom to top in the mounting groove 23 and facilitates the suction fan 3 to discharge airflow downwards.

[0048] Among them, such as Figure 1 As shown, the depth of the mounting groove 23 is greater than the axial dimension of the suction fan 3. This increases the flow space for airflow, which is beneficial for air circulation and thus improves ventilation efficiency.

[0049] In some embodiments, the suction fan 3 is disposed on the inner top wall of the mounting groove 23, and the suction fan 3 and the outlet end of the suction port 22 are axially opposite each other.

[0050] Specifically, the suction fan 3 can be configured as a centrifugal fan with radially arranged blades. Airflow enters from the center of the impeller and is ejected radially (perpendicular to the axis of rotation, i.e., perpendicular to the axis of the suction fan 3). After being drawn into the center of the impeller, the air is accelerated radially due to centrifugal force, forming a "diffusion" airflow. This allows more air in the air guide trough 21 to be drawn into the air intake 22 and then discharged through the suction fan 3, achieving centralized air delivery, increasing the air volume, and making the output airflow more stable. Figure 1As shown, the suction fan 3 is installed on the inner top wall of the mounting groove 23. A hanging hole can be provided on the inner top wall of the mounting groove 23, and a hook can be provided on the suction fan 3 so that the suction fan 3 can be hung on the inner top wall of the mounting groove 23. Alternatively, connecting parts, such as bolts and screws, can be sequentially inserted through the suction fan 3 and the inner top wall of the mounting groove 23 so that the suction fan 3 is threadedly connected to the inner top wall of the mounting groove 23. The connection method between the suction fan 3 and the inner top wall of the mounting groove 23 is diverse and flexible, and is not limited to the one described in this embodiment.

[0051] The exhaust fan 3 and the exhaust port 22 are axially aligned, meaning that the axis of the exhaust fan 3 coincides with the axis of the exhaust port 22. In other words, the exhaust fan 3 and the exhaust port 22 are concentrically distributed. This allows hot air coming out of the exhaust port 22 to directly enter the exhaust fan 3 axially and then flow out radially, improving airflow efficiency.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the bottom of the seat cushion body 1 has a downward-open mounting cavity 12, and multiple ventilation holes 11 are connected to the mounting cavity 12. The ventilation structure 2 is installed in the mounting cavity 12.

[0053] Therefore, by installing the ventilation structure 2 inside the mounting cavity 12, the space occupied by the ventilation structure 2 is saved, and it is avoided from occupying other space outside the seat cushion body 1, which improves the structural compactness and simplification of the seat ventilation assembly 100. In addition, the ventilation structure 2 can support the seat cushion body 1, making the overall structure of the seat cushion body 1 stable.

[0054] The multiple ventilation holes 11 are all connected downward to the mounting cavity 12, so that the ventilation structure 2 in the mounting cavity 12 can receive the hot air flowing from the multiple ventilation holes 11 into the mounting cavity 12, that is, directly realize the air circulation, avoid the air flowing to other places, which is quick and convenient and has high air guiding efficiency.

[0055] In practical design, refer to the appendix. Figure 1 and attached Figure 2 As shown, the shape and size of the mounting cavity 12 should be adapted to the shape and size of the ventilation structure 2 so that the ventilation structure 2 can be stably installed in the mounting cavity 12 to ensure the comfort of the human body.

[0056] In some embodiments, the thickness of at least a portion of the ventilation structure 2 gradually decreases from one end near the air intake 22 to the other end away from the air intake 22.

[0057] Specifically, such as Figure 1As shown, in the front-to-back direction of the seat, the thickness of a portion of the ventilation structure 2 on the rear side of the air intake 22 can be set to gradually decrease from front to back, that is, from the end near the air intake 22 to the end away from the air intake 22. In this way, it can adapt to the shape of the mounting cavity 12, so that the thickness of the rear part of the ventilation structure 2 can be set to be thicker, thereby ensuring both ventilation performance and seating comfort. It also makes the ventilation structure 2 roughly flush with the bottom surface of the seat cushion body 1, so as to facilitate the overall assembly of the seat ventilation assembly 100 onto the seat cushion frame.

[0058] In other embodiments, the top surface of the ventilation structure 2 is constructed as a gently sloping surface 24.

[0059] Specifically, such as Figure 1 As shown, in the front-rear direction of the seat, the top surface of the ventilation structure 2 extends from top to bottom at an angle, so that the top surface of the ventilation structure 2 is constructed as a gently sloping surface 24. At the same time, the depth of the mounting cavity 12 is set to gradually decrease from front to back, so that the shape of the inner top wall of the mounting cavity 12 matches the shape of the top surface of the ventilation structure 2, so that the ventilation structure 2 can be matched and installed with the seat cushion body 1.

[0060] By constructing the top surface of the ventilation structure 2 as a gently sloping surface 24, it can be adapted to human body characteristics, thereby improving the passenger's riding comfort and enhancing the user experience.

[0061] In some embodiments, the radial dimensions of the plurality of ventilation holes 11 increase sequentially in the direction away from the air intake 22.

[0062] In other words, the radial dimension of the ventilation hole 11 that is closer to the air intake 22 is smaller, and the radial dimension of the ventilation hole 11 that is farther away from the air intake 22 is larger. This is because the closer the ventilation hole 11 is to the air intake 22, the easier it is for air to be drawn into the air intake 22, the stronger the airflow and the greater the ventilation volume. On the other hand, the farther the ventilation hole 11 is from the air intake 22, the less likely it is for air to be drawn into the air intake 22, the slower the airflow and the smaller the ventilation volume. This results in a significant difference in regional airflow, which can easily cause discomfort when riding.

[0063] Therefore, by increasing the radial dimension of the multiple ventilation holes 11 sequentially in the direction away from the air intake 22, the air volume of the ventilation holes 11 in different areas can be relatively evenly distributed, thereby avoiding obvious regional air volume differences and ensuring that passengers do not feel obvious regional air volume differences, thus improving the passenger riding experience.

[0064] In other embodiments, the depth of the air guide slot 21 increases in the direction away from the air intake 22.

[0065] In other words, the farther away from the air intake 22, the greater the depth of the air guide 21; the closer to the air intake 22, the smaller the depth of the air guide 21. This increases the airflow in the air guide 21 that is farther away from the air intake 22, further controls the regional airflow difference, and makes the airflow relatively evenly distributed in the air guide 21, thereby further reducing the regional airflow difference and improving the passenger's riding experience.

[0066] In other embodiments, the width of the air guide slot 21 increases in the direction away from the air intake 22.

[0067] In other words, the farther away from the air intake 22, the wider the air guide 21 is, and the closer to the air intake 22, the narrower the air guide 21 is. This can further increase the air volume of the air guide 21 that is farther away from the air intake 22, further control the regional air volume difference, and make the air volume relatively evenly distributed in the air guide 21, thereby further reducing the regional air volume difference and improving the passenger's riding experience.

[0068] In some embodiments, the width of the air guide slot 21 is A and satisfies: 25mm≤A≤30mm.

[0069] In other words, the width A of the air guide slot 21 can be set to 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, or other widths within the range of 25mm to 30mm. It can be flexibly set. It is understandable that the wider the air guide slot 21 is, the greater the ventilation volume. However, if the width of the air guide slot 21 is too large, it may reduce the structural strength of the ventilation structure component 2, making the ventilation structure component 2 prone to breakage and deformation, affecting the safety of passengers. On the other hand, if the width of the air guide slot 21 is smaller, although it increases the structural strength of the ventilation structure component 2, it will lead to a decrease in ventilation volume and affect ventilation efficiency.

[0070] Therefore, by setting the width A of the air guide slot 21 within a reasonable range of 25mm to 30mm, the structural strength of the ventilation structure 2 is ensured to be sufficient, thus ensuring the structural safety of the ventilation structure 2. At the same time, the ventilation requirements are met and the ventilation efficiency is improved.

[0071] In other embodiments, the depth of the air guide slot 21 is B and satisfies: 12mm≤B≤20mm.

[0072] In other words, the depth B of the air guide slot 21 can be set to 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, or other widths within the range of 12mm to 20mm. It can be understood that the greater the depth of the air guide slot 21, the greater the ventilation volume. However, if the depth of the air guide slot 21 is too large, it may reduce the structural strength of the ventilation structure 2, making the ventilation structure 2 prone to breakage and deformation, affecting passenger safety. On the other hand, if the depth of the air guide slot 21 is smaller, although it improves the structural strength of the ventilation structure 2, it will lead to a decrease in ventilation volume and affect ventilation efficiency.

[0073] Therefore, by setting the depth B of the air guide trough 21 within a reasonable range of 12mm to 20mm, the structural strength of the ventilation structure 2 is ensured to be sufficient, thus ensuring the structural safety of the ventilation structure 2. At the same time, the ventilation requirements are met and the ventilation efficiency is improved.

[0074] In other embodiments, the air guide slots 21 are distributed within a range of 230mm in length and 220mm in width to avoid the air guide slots 21 being set in an excessively large area, occupying too much space in the structure of the ventilation structure 2, resulting in insufficient structural strength of the ventilation structure 2, thereby reducing the safety of the ventilation structure 2.

[0075] In some embodiments, the seat ventilation assembly 100 further includes a cover 4, which is wrapped around the outside of the seat cushion body 1. The cover 4 has ventilation holes that are connected to the ventilation holes 11.

[0076] Specifically, the cover 4 is used to protect the seat ventilation assembly 100. The cover 4 wraps around the outside of the seat cushion body 1, preventing external foreign objects, dirt, etc. from damaging and contaminating the outer surface of the seat cushion body 1. The cover 4 has ventilation holes that are connected to the ventilation holes 11, so that external air can enter the ventilation holes 11 through the ventilation holes, and then enter the air guide channel 21 and the air intake 22 to achieve air circulation and ensure ventilation functionality.

[0077] In practical design, the cover 4 can be made of spliced ​​fabrics, such as woven fabrics, artificial leather, and genuine leather, offering flexible options. The woven fabric itself has a mesh structure, forming breathable holes, allowing for rapid and smooth airflow to the ventilation holes 11. This means the woven fabric does not require perforation to create breathable holes, and it is soft and comfortable. Artificial leather, also known as synthetic leather, is made by foaming or coating various formulations of PVC and PU onto a woven or non-woven fabric base. Genuine leather is made from raw animal hides processed by tanneries. When artificial leather or genuine leather is used for the cover 4, perforations need to be made to create breathable holes to meet ventilation requirements.

[0078] It also includes a sponge layer 5, which is disposed between the seat cushion body 1 and the cover 4.

[0079] Specifically, such as Figure 1 As shown, the sponge layer 5 is disposed between the upper surface of the seat cushion body 1 and the inner side of the cover 4. The sponge layer 5 has a mesh structure inside, which can be breathable and has high softness. Therefore, by setting the sponge layer 5, the ventilation requirements can be met while ensuring comfort, without affecting air circulation.

[0080] In actual design, the sponge layer 5 and the cover 4 can be bonded together with hot melt adhesive to make the sponge layer 5 and the cover 4 more stable.

[0081] This utility model also proposes a vehicle.

[0082] The vehicle according to an embodiment of the present invention includes a seat, the seat including the seat ventilation assembly 100 of any of the above embodiments.

[0083] The seat ventilation assembly 100 can be installed in the seating area of ​​the seat. By installing the seat ventilation assembly 100, the service life of the seat can be extended, the seat can be prevented from being corroded, the seat performance stability can be maintained, the safety of the seat can be improved, and the overall weight of the seat can be reduced due to fewer parts. Therefore, by installing a seat including the seat ventilation assembly 100 in the vehicle, it is beneficial to achieve vehicle weight reduction, improve vehicle safety and user experience, and reduce costs.
