Description

Technical Field

[0001] This application relates to the technical field of automotive interior products, and in particular to a seat cushion core. Background Technology

[0002] With the continuous increase in consumption in China's automotive aftermarket, car seat cushions have become a major consumer product for car owners. Choosing a comfortable and practical car seat cushion according to the season is particularly important. Nowadays, there are car seat cushions made of different materials such as synthetic fibers, artificial fur, and wool on the market.

[0003] Traditional seat cushions have poor breathability, so after prolonged use, it is difficult for sweat to escape from the user's buttocks and legs, causing the user to feel stuffy and uncomfortable, which needs to be improved. Utility Model Content

[0004] In order to improve the breathability of the seat cushion and enhance the user experience, this application provides a seat cushion.

[0005] The technical solution for a seat cushion core provided in this application is as follows:

[0006] A seat cushion core includes a core body, the core body includes a surface layer and a bottom layer, the surface layer has a plurality of upper shaped parts evenly distributed, the bottom layer has a plurality of lower support bodies evenly distributed, the upper shaped parts are provided with air vents, the lower support bodies are provided with support vents, and the support vents are connected to the air vents.

[0007] By adopting the above technical solution, when the user's buttocks come into contact with the upper deformable part, the ventilation cavity deforms, making the user's buttocks feel softer when in contact with the upper deformable part, which can effectively improve the user's comfort. At the same time, due to the presence of the lower support body and the connection between the support cavity and the ventilation cavity, it can effectively play a supporting role. Moreover, the heat generated by the buttocks and legs will be transferred to the support cavity through the ventilation cavity, thus ensuring good ventilation and improving the user's experience.

[0008] Preferably, the cross-sections of the air vent and the support cavity are both regular hexagonal, the number of support vents is the same as the number of air vents and they correspond one-to-one, and the wall of the support cavity is flush with the wall of the corresponding air vent.

[0009] By adopting the above technical solution, the ventilation cavity and the support cavity are in the shape of a regular hexagon, which helps to improve the structural strength of the upper deformation body and the lower support body, and improve the service life of the seat cushion core. The walls of the ventilation cavity and the support cavity are flush, which helps the hot air in the ventilation cavity to enter the support cavity more quickly and smoothly, thus ensuring a good heat dissipation effect.

[0010] Preferably, the surface layer further includes a first support ring, the number of which is the same as the number of air vents and corresponds one-to-one. The first support ring is embedded in the air vent, and the end of the first support ring away from the bottom layer is flush with the side of the surface layer away from the bottom layer. A first support strip is connected to the wall of the air vent, and the other end of the first support strip is connected to the outer wall of the first support ring. Several first support strips are provided in any air vent, and several first support strips in any air vent are distributed circumferentially along the first support ring in the same air vent.

[0011] By adopting the above technical solution, the first support ring is embedded in the ventilated cavity, which can enhance the structural strength of the upper shape-forming variant. Furthermore, by setting multiple first support strips that are spaced apart along the circumference of the first support ring between the ventilated cavity wall and the outer wall of the first support ring, the stability and structural strength of the upper shape-forming variant are further improved, which helps to maintain the shape of the ventilated cavity, ensure the breathability effect, and thus improve the user experience.

[0012] Preferably, the cross-section of the first support ring is a regular hexagon, and the distance from each point on the outer wall of the first support ring to the wall of the ventilated cavity is equal. There are six first support bars in any ventilated cavity. The length direction of the first support bar is perpendicular to the side wall of the first support ring. The extension lines of the six first support bars in the same ventilated cavity along the length direction of the first support bar intersect at the center of the circumcircle of the ventilated cavity.

[0013] By adopting the above technical solution, the first support ring has a regular hexagonal cross section and the distance from each point on the outer wall to the wall of the air vent is equal. This makes the air permeability between the wall of the air vent and the outer wall of the first support ring more uniform, reducing the possibility of poor local heat dissipation and ensuring the breathability of the seat cushion core and the user's experience.

[0014] Preferably, the bottom layer further includes a second support strip, the number of which is the same as the number of the first support strip and corresponds one-to-one. One end of the second support strip is fixedly connected to the wall of the support cavity, and the side of the second support strip near the surface is in contact with the end of the first support ring near the bottom layer.

[0015] By adopting the above technical solution, a second support strip is connected inside the support cavity wall, which is attached to the side near the surface and the side of the first support ring near the bottom layer, thereby enhancing the overall structural stability of the seat cushion core and ensuring that the breathable structure can play an effective role for a long time, thus maintaining good breathability and user experience.

[0016] Preferably, the bottom layer further includes a second support ring, the number of the second support rings being the same as the number of support cavities and corresponding one-to-one, the second support rings being embedded in the support cavities, the inner and outer surfaces of the first support ring being flush with the inner and outer surfaces of the first support ring, the end of the second support ring away from the surface being flush with the side of the bottom layer away from the surface, and the end of the second support ring near the surface being in contact with the end of the first support ring near the bottom layer.

[0017] By adopting the above technical solution, one end of the second support ring is attached to the first support ring, and the other end of the second support ring is flush with the side of the bottom layer away from the surface layer, which helps to disperse the pressure on the first support ring. The side wall of the second support ring is flush with the side wall of the first support ring, ensuring the breathability of the seat cushion core and improving the user experience.

[0018] Preferably, all the second support bars in the same support cavity intersect at the center of the circumscribed circle of the support cavity, and the two sides of the second support bars are flush with the two sides of the bottom layer.

[0019] By adopting the above technical solution, the second support strip in the same support cavity of the bottom layer intersects at the center of the outer circle of the support cavity and is flush with the two sides of the bottom layer, which enhances the support stability of the bottom layer, ensures the overall structure of the seat core is stable, guarantees the stability of breathability and support performance during long-term use, and improves the user experience.

[0020] Preferably, the inner core body further includes an edge banding, which is connected to the surface layer and the bottom layer sidewall.

[0021] By adopting the above technical solution, the surface layer and the bottom layer are fixed together by setting the edging, which enhances the connection stability between the two, strengthens the structural strength of the seat cushion core, and improves the service life of the seat cushion core.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. During use, the user's buttocks come into contact with the upper shape-shifting body, and then the ventilation cavity deforms, making the user's buttocks feel softer when in contact with the upper shape-shifting body, which can effectively improve the user's comfort. At the same time, due to the presence of the lower support body and the connection between the support cavity and the ventilation cavity, it can effectively provide support. Moreover, the heat generated by the buttocks and legs will be transferred to the support cavity through the ventilation cavity, thus ensuring good breathability and improving the user's experience.

[0024] 2. The ventilation cavity and support cavity are hexagonal, which helps to improve the structural strength of the upper shape and the lower support, and increase the service life of the seat core. The walls of the ventilation cavity and the support cavity are flush, which helps the hot air in the ventilation cavity to enter the support cavity more quickly and smoothly, thus ensuring good heat dissipation.

[0025] 3. The first support ring is embedded in the ventilated cavity, which can enhance the structural strength of the upper shape-forming variant. Furthermore, by setting multiple first support strips that are spaced apart along the circumference of the first support ring between the ventilated cavity wall and the outer wall of the first support ring, the stability and structural strength of the upper shape-forming variant are further improved, which helps to maintain the shape of the ventilated cavity, ensure the breathability, and thus improve the user experience.

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses a seat cushion core.

[0036] Example 1

[0037] Reference Figure 1 A cushion core includes an inner core body 1. The inner core body 1 includes a surface layer 11, a bottom layer 12, and an edge 13. One side surface of the surface layer 11 along the thickness direction of the surface layer 11 is fixedly connected to one side surface of the bottom layer 12 along the thickness direction of the bottom layer 12. The side wall of the surface layer 11 is flush with the side wall of the bottom layer 12. The edge 13 is fixedly connected to the side walls of the surface layer 11 and the bottom layer 12.

[0038] Reference Figure 1 and Figure 2 The surface layer 11 has a plurality of upper shaped variants 111 evenly distributed, each upper shaped variant 111 having a vent 1111. The vent 1111 penetrates the upper shaped variant 111 along the thickness direction of the surface layer 11. The bottom layer 12 has a plurality of lower support bodies 121 evenly distributed, each lower support body 121 having a support cavity 1211. The support cavity 1211 penetrates the lower support body 121 along the thickness direction of the bottom layer 12. The number of vent 1111 is the same as the number of support cavities 1211 and they correspond one-to-one. The cross-section of both the vent 1111 and the support cavity 1211 is a regular hexagon, and the cavity wall of the vent 1111 is flush with the cavity wall of the corresponding support cavity 1211.

[0039] Reference Figure 2 and Figure 3 The surface layer 11 also includes a first support ring 112. The number of first support rings 112 is the same as the number of air vents 1111 and they correspond one-to-one. The first support ring 112 is embedded in the air vent 1111. The cross-section of the first support ring 112 is a regular hexagon. The distance from each point on the outer wall of the first support ring 112 to the wall of the air vent 1111 is equal. The two ends of the first support ring 112 along the thickness direction of the surface layer 11 are flush with the two sides of the surface layer 11 along the thickness direction of the surface layer 11.

[0040] Reference Figure 3 and Figure 4 The surface layer 11 also includes a first support strip 113. The length direction of the first support strip 113 is perpendicular to the thickness direction of the surface layer 11. One end of the first support strip 113 is fixedly connected to the wall of the vent cavity 1111, and the other end of the first support strip 113 is fixedly connected to the outer wall of the first support ring 112. The surface of the first support strip 113 away from the bottom layer 12 is flush with the surface of the edging 13 away from the bottom layer 12. Several first support strips 113 are provided in any vent cavity 1111, and these strips are spaced apart circumferentially along the first support ring 112. In this embodiment, six first support strips 113 are provided in any vent cavity 1111. The length direction of the first support strip 113 is perpendicular to the side wall of the first support ring 112, and the extension lines of the six first support strips 113 along their length direction intersect at the center of the circumscribed circle of the vent cavity 1111.

[0041] Reference Figure 4 and Figure 5The bottom layer 12 also includes a second support strip 122. The number of second support strips 122 is the same as the number of first support strips 113 and they correspond one-to-one. One end of the second support strip 122 is fixedly connected to the cavity wall of the support cavity 1211. The ends of all the second support strips 122 in the same support cavity 1211 that are away from the cavity wall of the support cavity 1211 intersect at the center of the circumscribed circle. The two side surfaces of the second support strip 122 along the thickness direction of the bottom layer 12 are flush with the two side surfaces of the bottom layer 12 along the thickness direction of the bottom layer 12. The side surface of the second support strip 122 near the surface layer 11 is in contact with the end of the first support ring 112 near the bottom layer 12.

[0042] The implementation principle of Example 1 is as follows: During use, the user's buttocks come into contact with the upper deformable part 111 and the first support ring 112, causing the upper deformable part 111 and the first support ring 112 to deform, and the pressure is transmitted to the lower support body 121. Because of the presence of the second support bar 122, it can play a good supporting role. There are six second support bars 122, and the included angle between adjacent second support bars 122 is 60°. Since the second support bars 122 are connected to the cavity wall of the support cavity 1211, the length of each second support bar 122 is equal, so that when subjected to pressure, the second support bar 122 is subjected to more uniform force and has a smaller deformation, which greatly improves the supporting effect and ensures that the problem of poor heat dissipation caused by the deformation of the lower support body 121 under long-term use does not occur.

[0043] Example 2

[0044] Reference Figure 6 The difference between this embodiment and Embodiment 1 is that the bottom layer 12 includes a second support ring 123 and a second support strip 122. The number of second support rings 123 is the same as the number of support cavities 1211 and they correspond one-to-one. The second support rings 123 are embedded in the support cavities 1211. The cross-section of the second support ring 123 is a regular hexagon. The inner and outer surfaces of the second support ring 123 are flush with the inner and outer surfaces of the first support ring 112. The two ends of the second support ring 123 along the thickness direction of the bottom layer 12 are flush with the two sides of the bottom layer 12 along the thickness direction of the bottom layer 12. The end of the second support ring 123 near the surface layer 11 is in contact with the end of the first support ring 112 near the bottom layer 12. The number of second support bars 122 is the same as the number of first support bars 113 and they correspond one-to-one. One end of the second support bar 122 is fixedly connected to the cavity wall of the support cavity 1211, and the other end of the second support bar 122 is fixedly connected to the outer wall of the second support ring 123. The surface of the second support bar 122 away from the surface layer 11 is flush with the surface of the edging 13 away from the surface layer 11. The length direction of the second support bar 122 is perpendicular to the side wall of the second support ring 123. The extension lines of the six second support bars 122 in the same support cavity 1211 along the length direction of the second support bar 122 intersect at the center of the circumcircle of the support cavity 1211.

[0045] The implementation principle of Example 2 is as follows: When a heavy user uses the device, the user will come into contact with the ventilation cavity 1111. When the ventilation cavity 1111 deforms, the upper end of the first support ring 112 is flush with the upper surface of the upper deformable body 111, the lower end of the first support ring 112 is in contact with the upper end of the second support ring 123, and the lower end of the second support ring 123 is flush with the lower surface of the lower support body 121. Therefore, the user's buttocks will come into contact with the first support ring 112, which can effectively distribute pressure, reduce the deformation of the upper deformable body 111 and the lower support body 121, and avoid the problem of poor breathability caused by excessive deformation of the lower support body 121.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
