[0027] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0028] The following refers to Figures 1 - 5 to describe the seat cushion device 100 and the vehicle according to an embodiment of the present utility model.

[0029] The seat cushion device 100 according to an embodiment of the present utility model includes: a first foam member 10 and a second foam member 20. The first foam member 10 and the second foam member 20 are fixedly connected, and the density of the first foam member 10 is greater than the density of the second foam member 20.

[0030] Among them, the first foam member 10 and the second foam member 20 are fixedly connected. For example, the first foam member 10 and the second foam member 20 can be fixedly connected by adhesion, or the first foam member 10 and the second foam member 20 can be fixedly connected by rivets. However, the present utility model is not limited thereto, and the first foam member 10 and the second foam member 20 can also be fixedly connected by other means, as long as the first foam member 10 and the second foam member 20 are fixedly connected. In this application, the case where the first foam member 10 and the second foam member 20 are fixedly connected by a snap ring nail is taken as an example for description, and the first foam member 10 covers the outer surface of the second foam member 20.

[0031] Specifically, the first foam member 10 and the second foam member 20 can be first cut and formed according to the design requirements of the seat cushion device 100, and the cover is laid on the first foam member 10 and the second foam member 20. Holes are drilled at the pre-designed positions on the cover, the first foam member 10 and the second foam member 20. The positions of the holes need to be accurately aligned to ensure that the snap ring nail can smoothly pass through and fix the first foam member 10, the second foam member 20 and the cover, so as to form a firm connection. The assembly is simple and fast, which is beneficial to improving the production efficiency of the seat cushion device 100 and reducing the production cost. It can be explained that the material of the cover can be cloth, leather or synthetic material, etc., and can be reasonably selected and customized according to the design requirements of the seat cushion device 100, so as to improve the appearance quality of the seat cushion device 100.

[0032] Since the density of the first foam member 10 is greater than the density of the second foam member 20, the weight of the same volume of the second foam member 20 is less than the weight of the first foam member 10. By using the second foam member 20 and the first foam member 10 to be formed in cooperation in the seat cushion device 100, compared with the case where all the first foam members 10 are used in the seat cushion device 100, the weight of the seat cushion device 100 can be reduced, which is beneficial to the lightweight design of the vehicle.

[0033] Furthermore, the first foaming member 10 can be configured as a polyurethane (PUR) foam with a relatively high density, which can provide good support and resilience, effectively disperse body pressure, and reduce the discomfort caused by sitting for a long time. The second foaming member 20 can be configured as a high-expansion polypropylene member (EPP). The EPP material has a low density, is lightweight, and has good shock absorption and buffering performance. It can effectively absorb external impacts, protect the internal structure of the cushion device 100 and the safety of users. It can also make the entire cushion device 100 reduce the overall weight while maintaining sufficient support force, which is convenient for handling and installation. In addition, the EPP material is inexpensive and can be recycled, meeting the modern environmental protection concept.

[0034] Furthermore, the first foaming member 10 can be arranged at the top of the cushion device 100 to support the user, so as to provide the comfort and support of the cushion device 100. The second foaming member 20 can be located inside the first foaming member 10 as an internal support structure to enhance the durability and stability of the cushion device 100. Therefore, by applying the first foaming member 10 made of polyurethane foam and the second foaming member 20 made of high-expansion polypropylene to the cushion device 100, not only the support performance of the cushion device 100 is ensured, but also the weight of the cushion device 100 can be reduced. Furthermore, it is beneficial to improve the comfort and durability of the cushion device 100, is also beneficial to the lightweight design of the vehicle, and can also reduce the manufacturing cost of the cushion device 100.

[0035] According to the cushion device 100 of the embodiment of the present invention, by replacing part of the first foaming member 10 with the second foaming member 20 and fixedly connecting the first foaming member 10 and the second foaming member 20 to jointly form the cushion device 100, compared with the case where all the first foaming members 10 are used in the cushion device 100, the weight of the cushion device 100 can be reduced, which is beneficial to the lightweight design of the vehicle.

[0036] In some embodiments of the present invention, as Figure 4 shown, the cushion device 100 may further include: a first skeleton 11. The first skeleton 11 can be a tightening wire. The first foaming member 10 is wrapped around the first skeleton 11, which can provide protection and buffering for the first skeleton 11, thereby reducing the risk of damage to the first skeleton 11 caused by external impacts, abrasions or corrosion. It also helps to maintain the temperature stability of the first skeleton 11 and prevent the performance degradation of the first skeleton 11 caused by temperature changes. The first skeleton 11 can enhance the support force of the first foaming member 10, which helps the cushion device 100 to quickly return to its original shape after being stressed, maintain the shape and elasticity of the cushion device 100, and is beneficial to extending the service life of the cushion device 100. The combined use of the first foaming member 10 and the first skeleton 11 can also make the cushion device 100 fit the human body curve better, thereby providing better support and comfort for the user and helping to reduce the fatigue of the user during long-term sitting.

[0037] In some embodiments of the present utility model, the first foam member 10 and the first skeleton 11 can be integrally formed, which can simplify the production process of the seat cushion device 100, reduce the assembly steps, thereby improving the production efficiency of the seat cushion device 100. And through precise design and integral forming technology, the formed first skeleton 11 is fixed in the mold, and the raw material of the first foam member 10 is poured into the mold, so that the raw material of the first foam member 10 fully fills the mold and wraps the first skeleton 11, without wasting the raw material at the connection between the first foam member 10 and the first skeleton 11, and can maximize the utilization of the raw materials of the first foam member 10 and the first skeleton 11, thereby reducing the production cost of the seat cushion device 100.

[0038] In addition, after the first foam member 10 and the first skeleton 11 are integrally formed, the first skeleton 11 can further enhance the supporting force of the first foam member 10, making the structure of the seat cushion device 100 more firm and durable, capable of effectively resisting external pressure and impact, maintaining the shape and stability of the seat cushion device 100. Even when the seat cushion device 100 is used for a long time or bears heavy objects, it can effectively reduce the deformation and collapse phenomenon, and maintain the flatness and comfort of the seat cushion device 100.

[0039] In some embodiments of the present utility model, as Figure 5 shown, the seat cushion device 100 may further include: a second skeleton 21. The second skeleton 21 can be a wire skeleton, and the shape of the wire skeleton can be reasonably set according to the assembly positions of the first foam member 10 and the second foam member 20. For example: the wire skeleton can form a polygonal ring along the edge of the second foam member 20. The part of the second foam member 20 that wraps the second skeleton 21, for example: the second foam member 20 wraps one-half of the second skeleton 21, or the second foam member 20 wraps one-third of the second skeleton 21. However, the present utility model is not limited thereto, and the second foam member 20 can also wrap other proportional parts of the second skeleton 21, as long as the part of the second foam member 20 that wraps the second skeleton 21 is sufficient. The second skeleton 21 has good strength and rigidity, and can provide support for the second foam member 20. The second foam member 20 wraps the second skeleton 21, and can form a firm bonding layer, which helps the second skeleton 21 to maintain a stable shape. Even when the second skeleton 21 is subjected to external force extrusion or deformation, it can quickly return to its original shape, and can further enhance the overall supporting force of the seat cushion device 100, thereby extending the service life of the seat cushion device 100.

[0040] In some embodiments of the present utility model, the second foam member 20 and the second skeleton 21 can be integrally formed, which can simplify the production process of the seat cushion device 100, reduce the assembly steps, thereby improving the production efficiency of the seat cushion device 100. And through precise design and integral forming technology, the formed second skeleton 21 is fixed in the mold, and the raw material of the second foam member 20 is poured into the mold, so that the raw material of the second foam member 20 fully fills the mold and wraps the second skeleton 21, without wasting the raw material at the connection between the second foam member 20 and the second skeleton 21, and can maximize the utilization of the raw materials of the second foam member 20 and the second skeleton 21, thereby reducing the production cost of the seat cushion device 100.

[0041] Compared with the separate second foam member 20 and second skeleton 21, the integrally formed second foam member 20 and second skeleton 21 form an integral structure, having higher integrity, stability and buffering performance, and can withstand greater loads and stresses, so that the seat cushion device 100 can better resist deformation when subjected to external forces, and improve the stability of the seat cushion device 100.

[0042] In some embodiments of the present utility model, as Figure 5 shown, the second skeleton 21 can have a fixed mounting portion 22 for mating and assembling with the first foam member 10, and the position of the fixed mounting portion 22 on the second skeleton 21 corresponds to the position of the holes drilled in the first foam member 10. For example, the fixed mounting portion 22 can be located at the edge position of the second skeleton 21, which is beneficial to evenly distribute the load borne by the seat cushion device 100 to the second skeleton 21 and the second foam member 20, avoiding damage or deformation of the seat cushion device 100 caused by excessive local pressure, and thus being beneficial to extending the service life of the seat cushion device 100.

[0043] It can be explained that a plurality of mounting holes 24 can be provided on the fixed mounting portion 22, and the plurality of mounting holes 24 correspond one-to-one to the plurality of holes drilled in the first foam member 10, and the first foam member 10 and the second skeleton 21 are fixedly connected by snap rings, thereby realizing the fixed connection between the first foam member 10 and the second foam member 20.

[0044] In some embodiments of the present utility model, as Figure 3 shown, the second foam member 20 can be formed with an avoidance opening 23, and the fixed mounting portion 22 is located in the avoidance opening 23, which can avoid interference between the fixed mounting portion 22 and the second foam member 20, and thus reduce the fixing difficulty and the risk of stress concentration between the fixed mounting portion 22 and the first foam member 10.

[0045] In some embodiments of the present utility model, as Figure 3 and Figure 5As shown, there can be multiple avoidance openings 23 and fixed mounting parts 22. For example, the number of both the avoidance openings 23 and the fixed mounting parts 22 can be two, three, four, etc. However, the present utility model is not limited thereto, and there can also be other numbers of avoidance openings 23 and fixed mounting parts 22, as long as there are multiple avoidance openings 23 and multiple fixed mounting parts 22. The multiple avoidance openings 23 and the multiple fixed mounting parts 22 correspond one by one, so that each fixed mounting part 22 can be fixedly connected to the first foaming member 10 through the corresponding avoidance opening 23, thereby making the connection between the first foaming member 10 and the second foaming member 20 more stable. Moreover, the multiple fixed mounting parts 22 can disperse stress to the entire cushion device 100, avoiding excessive single-point force on the cushion device 100 and damage, which is beneficial to improving the durability and service life of the cushion device 100.

[0046] In some embodiments of the present utility model, the first foaming member 10 can be configured as a polyurethane member (i.e., the above-mentioned polyurethane PUR foam), which has a relatively high density, can provide good support and resilience, can effectively disperse body pressure, and reduce the discomfort caused by long-term sitting postures. The second foaming member 20 can be configured as a high-foaming polypropylene member (i.e., the above-mentioned high-foaming polypropylene member EPP). The EPP material has a low density, is light in weight, and has good shock-resistant and buffering performance, can effectively absorb external impacts, protect the internal structure of the cushion device 100 and user safety, and can also make the entire cushion device 100 reduce the overall weight while maintaining sufficient support force, which is convenient for handling and installation. In addition, the EPP material is inexpensive and can be recycled, meeting the modern environmental protection concept.

[0047] By applying the first foaming member 10 made of polyurethane material and the second foaming member 20 made of high-foaming polypropylene material to the cushion device 100, it not only ensures the support performance of the cushion device 100 but also can reduce the weight of the cushion device 100, which is beneficial to improving the comfort and durability of the cushion device 100, is also beneficial to the lightweight design of the vehicle, and can also reduce the manufacturing cost of the cushion device 100.

[0048] The vehicle according to the embodiment of the present utility model includes the cushion device 100 of the above embodiment, which can reduce the weight of the cushion device 100 on the premise of ensuring the support performance of the cushion device 100, which is beneficial to the lightweight design of the vehicle, and can also reduce the manufacturing cost of the cushion device 100.
