Example 1
In order to solve the problem that in the prior art, a cushion with unchanged rigidity easily causes fatigue of buttocks of a driver and influences riding experience, as shown in fig. 1-3, the embodiment discloses an automobile seat cushion 10, the automobile seat cushion 10 comprises a cushion foaming layer 110, and the periphery of the cushion foaming layer 110 is wrapped with a cushion surface cover 120; a pressure detection unit 130 is arranged between one side of the cushion foaming layer 110 close to the cushion surface cover 120 and the cushion surface cover 120, an adjusting unit 140 and a hanging part 150 which are connected with each other are arranged on one side of the cushion foaming layer 110 far away from the cushion surface cover 120, and the hanging part 150 is used for supporting the cushion foaming layer 110; wherein the pressure detecting unit 130 detects body pressure distribution information of an occupant on the seat cushion 10 of the car seat and transmits the same to the adjusting unit 140, and the adjusting unit 140 changes the position of the hanging part 150 with respect to the cushion foam layer 110 according to the body pressure distribution information to adjust the rigidity of the cushion foam layer 110.
Specifically, in the present embodiment, the pressure detecting unit 130 detects the body pressure distribution information of the occupant on the seat cushion 10 of the vehicle seat and transmits the same to the adjusting unit 140, and the adjusting unit 140 adjusts the rigidity of the cushion foam layer 110 according to the body pressure distribution information, thereby solving the problem of fatigue of the buttocks of the occupant due to the body pressure distribution in one state for a long time after the occupant sits for a long time. Therefore, this embodiment provides an intelligent and full-automatic car seat cushion 10, so that the passengers on the car seat cushion 10 can obtain better riding experience, especially for the drivers and passengers with longer riding time, the car seat cushion 10 will effectively improve the fixed body pressure distribution state of the existing car seat cushion 10, obtain better riding comfort, make the car seat cushion 10 more intelligent and automatic, and can actively sense the passenger state and make corresponding adjustment.
More specifically, the adjusting unit 140 changes the position of the suspension portion 150 with respect to the cushion foam layer 110 according to the body pressure distribution information to adjust the rigidity of the cushion foam layer 110 may be to adjust the supporting area of the suspension portion 150 for supporting the cushion foam layer 110, such as a case where the suspension portion 150 is stretched to be longer to increase the supporting area; it is also possible to support the extruded cushion foam layer 110 for adjusting the suspension portion 150 so as to change the thickness of the cushion foam layer 110 and thus the rigidity thereof; the suspension portion 150 may also be adjusted to change the distribution of the support points supporting the cushion foam layer 110 relative to the support points supporting the cushion foam layer 110 so as to change the rigidity of the cushion foam layer 110, specifically, the pressure detecting unit 130 actively senses the distribution information of the passenger pressure, and the adjusting unit 140 is driven in real time according to the distribution information of the passenger pressure by a comfort body pressure curve set in the ECU (electronic control unit for automobile) to act, so as to adjust the rigidity of the cushion foam layer 110, and make the occupant obtain more intelligent feeling and more comfortable riding experience.
As shown in fig. 1 to 3, according to another embodiment of the present embodiment, which discloses an automobile seat cushion 10, the adjusting unit 140 includes controllers electrically connected to each other, which may be the ECU mentioned above, and further includes a driver 160 and an adjusting assembly; wherein the pressure detecting unit 130 detects body pressure distribution information of an occupant on the car seat cushion 10 and transmits the same to the controller; the controller controls the driver 160 to drive the adjusting assembly to move according to the body pressure distribution information so as to link the suspension portion 150 to move to change the position of the suspension portion 150 relative to the cushion foam layer 110 to adjust the rigidity of the cushion foam layer 110. The car seat cushion 10 further includes two cushion frames 170, the cushion frames 170 being located on a side of the cushion foam layer 110 remote from the cushion cover 120.
Because of the large variation in human body size, it is not a certain value but is distributed over a range. If asians are 151-188 cm in height, we can only use a certain value when designing, and we cannot use the average value as we generally understand, how does we determine which value to use? This is the problem to be solved by the percentile approach. The definition of percentiles is as follows: the percentile represents the percentage of people having a certain body size and less than that size to the total number of people in the statistical subject. Taking the 5 th percentile, human height dimension as an example, it is indicated that there is 5% human height equal to or less than that dimension. In this embodiment, according to the difference in the passenger sitting body pressure distribution of different percentiles, when the rigidity of the cushion foam layer 110 needs to be increased, the driver 160 drives the adjustment assembly to move so that the linkage suspension 150 moves toward the side close to the cushion foam layer 110, and when the rigidity of the cushion foam layer 110 needs to be reduced, the driver 160 drives the adjustment assembly to move so that the linkage suspension 150 moves toward the side far from the cushion foam layer 110.
For example, when the pressure detecting unit 130 detects that the body pressure distribution of the occupant on the car seat cushion 10 is near the front of the cushion (i.e., a position near the right side of the car seat cushion 10 in fig. 2), the driver 160 drives the adjusting assembly to move so that the linked suspension portion 150 swings clockwise around the right cushion frame 170 and stretches, and conversely, swings counterclockwise around the right cushion frame 170 and stretches to adjust the rigidity of the cushion foam layer 110.
As shown in fig. 1-3, according to another embodiment of the present embodiment, another embodiment of the present embodiment discloses an automotive seat cushion 10, the adjustment assembly includes a rocker 1401 and two links 1402; wherein one end of the hanging portion 150 is connected to one end of one of the seat cushion frames 170.
