[0033] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0034] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "radial", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0035] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0036] Figure 1 is a schematic application diagram of a seat in the prior art. As Figure 1 , Figure 2 shown, in the prior art, when a driver is driving a vehicle, the feet are placed on the accelerator pedal 110, the main body of the seat cushion 120 is a foam body, and a thigh support area 121 for the occupant's thigh to lean on is provided on the front surface of the foam body to provide support for the front part of the driver's thigh.

[0037] When the driver refuels, the feet step on the accelerator pedal 110 downward with force, causing the accelerator pedal 110 to rotate, and at the same time driving the front part of the thigh to press the seat cushion 120 downward. However, the foam body lacks compression space, resulting in difficulty in shrinking the foam body, generating a large stress, which will bring a reaction force to the thigh. Therefore, the driver needs to increase the downward pressure of the leg to complete the refueling action, thus increasing the squeezing force on the front part of the driver's thigh, and further increasing the discomfort of the driver when operating the accelerator.

[0038] In order to reduce the discomfort of the driver and passengers during driving, some vehicles are attached with a layer of soft sponge 130 in the thigh support area. The additional soft sponge 130 will increase the overall cost of the seat cushion.

[0039] Therefore, the present utility model proposes a technical solution that can solve the problem of the reaction pressure brought by the foam to the thigh in the prior art and the problem of the increase in the cost of the seat cushion caused by adding a soft sponge layer.

[0040] Figure 3 It is a schematic structural diagram of the seat cushion in the first embodiment of the present utility model, as Figure 3 shown, and with reference to Figures 4 to 9 , the embodiment of the present utility model provides a seat cushion, including a seat cushion foam 200. A first support area 220 is provided on the side of the seat cushion foam 200 away from the seat back. A plurality of softening grooves 230 and / or softening holes are provided in the first support area 220.

[0041] In the embodiment of the present utility model, when the driver is driving, the seat cushion foam 200 provides support for the driver's thigh. The first support area 220 is used to support the front part of the occupant's thigh. Since the softening grooves 230 and / or softening holes are provided in the first support area 220, when the driver steps on the accelerator, the front part of the thigh presses down on the seat cushion foam 200, and the first support area 220 of the seat cushion foam 200 is squeezed and deformed. The softening grooves 230 and / or softening holes provide a compression space for the deformation of the seat cushion foam 200, enabling the seat cushion foam 200 to contract, reducing the reaction force brought by the seat cushion foam 200 to the driver's thigh, and avoiding increasing the discomfort of the driver when operating the accelerator. At the same time, the soft sponge is cancelled, and the usage amount of the foam material is reduced. The structure is simpler, and the overall cost of the vehicle seat is reduced.

[0042] Furthermore, the arrangement of the softening grooves 230 and / or softening holes can allow air to circulate better, reduce the heat accumulation on the surface of the seat cushion, and thus provide a cooler driving experience for the driver.

[0043] As Figure 4 , Figure 6 shown, in an embodiment of the present utility model, the first support area 220 includes a peripheral area 221 and two sub-support areas 222. The two sub-support areas 222 are arranged at intervals along the width direction of the seat. The peripheral area 221 surrounds the sub-support areas 222; the sub-support areas 222 are in a shape-matching fit with the driver's thigh. The arrangement of the sub-support areas 222 increases the contact area between the sub-support areas 222 and the driver's thigh, enables the driver's thigh to be fully supported, reduces the pressure points, and thus allows the body to reach a relatively relaxed state, improving the driver's driving experience.

[0044] In an embodiment of the present utility model, the depth of the softening groove 230 in the sub-support area 222 is greater than the depth of the softening groove 230 in the peripheral area 221; and / or, the depth of the softening holes in the sub-support area 222 is greater than the depth of the softening holes in the peripheral area 221.

[0045] In this embodiment, by adjusting the depth of the softening groove 230 and / or the softening holes, the support of the seat cushion foam 200 on the legs can be adjusted. The greater the depth of the softening groove 230, the greater the compression space, the greater the deformation that the seat cushion foam 200 can generate, and the weaker the support, so as to reduce the reaction force brought by the seat cushion foam 200 to the driver's thigh, thereby meeting the different requirements of the driver for the softness of the seat cushion.

[0046] In an alternative embodiment of the present utility model, the width of the softening groove 230 in the sub-support area 222 is greater than the width of the softening groove 230 in the peripheral area 221; and / or, the diameter of the softening holes in the sub-support area 222 is greater than the diameter of the softening holes in the peripheral area 221.

[0047] Similarly, by adjusting the width of the softening groove 230 and / or the diameter of the softening holes, the support of the seat cushion foam 200 on the legs can be adjusted. The greater the width of the softening groove 230 and / or the diameter of the softening holes, the greater the compression space, the greater the deformation that the seat cushion foam 200 can generate, and the weaker the support, so as to reduce the reaction force brought by the seat cushion foam 200 to the driver's thigh, thereby meeting the different requirements of the driver for the softness of the seat cushion.

[0048] Specifically, the widths and depths of the multiple softening grooves 230 and / or softening holes in the peripheral area 221 are kept consistent; the widths and depths of the multiple softening grooves 230 and / or softening holes in the sub-support area 222 are kept consistent. Or, along the direction from the sub-support area 222 to the peripheral area 221, the width and depth of the softening groove 230 decrease, and the diameter and depth of the softening holes decrease.

[0049] As Figures 4 - 8 shown, in an embodiment of the present utility model, the softening groove 230 extends along a preset line segment, and the preset line segment includes a straight line segment, a curved line segment, or a combination of the two, so as to promote better air circulation. Similarly, the softening groove 230 can also be in regular shapes such as strip-shaped or polygonal, or other irregular ring structures.

[0050] As Figure 3 、 Figure 4 shown, in an embodiment of the present utility model, the softening groove 230 is linear and extends along the length direction of the seat.

[0051] As Figure 5 、 Figure 6As shown, in another alternative embodiment of the present utility model, the softening tank 230 is linear and extends along the width direction of the seat.

[0052] As Figure 7 shown, in an alternative embodiment of the present utility model, some of the softening tanks 230 are linear and extend along the width direction of the seat. Some of the softening tanks 230 are curved, and a plurality of softening tanks 230 are evenly spaced.

[0053] As Figure 8 shown, in another alternative embodiment of the present utility model, the softening tank 230 is linear, some of the softening tanks 230 extend along the length direction of the seat, some of the softening tanks 230 extend along the width direction of the seat, and at least some of the softening tanks 230 extend along a preset straight line, and the included angle between the preset straight line and the width direction of the seat is greater than 0° and less than 90°.

[0054] In an embodiment of the present utility model, the number of the softening tanks 230 is multiple, and a plurality of softening tanks 230 are spaced from each other. The softening tanks 230 extend along the length direction or the width direction of the seat. Or, at least some of the softening tanks 230 extend along the length direction of the seat, and at least some of the softening tanks 230 extend along the width direction of the seat, so that a plurality of softening tanks 230 crisscross to form a network structure. Or, at least some of the softening tanks 230 extend along a preset straight line, and the included angle between the preset straight line and the width direction of the seat is greater than 0° and less than 90°, so as to form an irregular arrangement.

[0055] In an embodiment of the present utility model, a second support area 210 is further provided on the seat cushion foam 200. The second support area 210 and the first support area 220 are located on the same side of the seat cushion foam 200. The second support area 210 is connected to the first support area 220, and the second support area 210 is used to support the driver's buttocks. Further, the first support area 220 and the second support area 210 are integrally formed, which can prevent the deformation of the seat cushion and ensure the flatness of the seat cushion.

[0056] In an embodiment of the present utility model, the softening holes are arranged in a rectangular array on the seat cushion. Similarly, the softening holes can also be arranged irregularly on the seat cushion. The softening holes are in regular shapes such as circular, oval, polygonal, or other irregular shapes.

[0057] As Figure 9 shown, the present utility model further provides a seat, which includes a seat frame 300 and a seat cushion as in any one of the above embodiments, so as to have all the effects of the seat cushion. The seat cushion is assembled on the seat frame 300.

[0058] Further, the seat further includes a seat cushion cover 400, and the seat cushion cover 400 is wrapped on the seat cushion foam 200.

[0059] The present utility model further provides a vehicle, including the seat cushion of the above embodiment.
