Detailed Implementation

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The following is for reference. Figure 1 A seat assembly 100 for a vehicle according to an embodiment of the present invention is described.

[0021] like Figure 1 As shown, the vehicle seat assembly 100 according to the present invention includes: a seat frame 1, the seat frame 1 including a seat cushion frame 11; a flexible seat cushion 2, the flexible seat cushion 2 disposed in the seat cushion frame 11; and a hardness adjustment mechanism 3, the hardness adjustment mechanism 3 disposed between the seat cushion frame 11 and the flexible seat cushion 2. The hardness adjustment mechanism 3 includes: a first flexible member 31 and a second flexible member 32. The first flexible member 31 has a circular cross-sectional structure, and the second flexible member 32 is embedded in the first flexible member 31 and has an elliptical cross-sectional structure. The central axes of the first flexible member 31 and the second flexible member 32 are collinear. The second flexible member 32 has a different hardness than the first flexible member 31. The hardness adjustment mechanism 3 is rotatable about the central axis of the first flexible member 31 to adjust the dimensional ratio of the first flexible member 31 and the second flexible member 32 along the height direction of the seat assembly 100.

[0022] The seat frame 1 includes a seat cushion frame 11, and a flexible seat cushion 2 is disposed on the seat cushion frame 11. In some embodiments of this application, the flexible seat cushion 2 is placed on the seat cushion frame 11. In some embodiments of this application, the flexible seat cushion 2 is adhered to the seat cushion frame 11. A hardness adjustment mechanism 3 is disposed between the seat cushion frame 11 and the flexible seat cushion 2. The hardness adjustment mechanism 3 includes a first flexible member 31 and a second flexible member 32. The cross-sectional structure of the first flexible member 31 is circular or approximately circular, and the second flexible member 32 is embedded within the first flexible member 31, and the cross-sectional structure of the second flexible member 32 is elliptical or approximately elliptical.

[0023] The central axes of the first flexible member 31 and the second flexible member 32 are collinear. The second flexible member 32 and the first flexible member 31 have different hardnesses. As some embodiments of this application, the hardness of the second flexible member 32 is greater than that of the first flexible member 31. As some embodiments of this application, the hardness of the first flexible member 31 is greater than that of the second flexible member 32. This application will describe the situation with the second flexible member 32 having a greater hardness than the first flexible member 31 as an example. The hardness adjustment mechanism 3 can rotate about the central axis of the first flexible member 31 to adjust the dimensional ratio of the first flexible member 31 and the second flexible member 32 along the height direction of the seat assembly 100.

[0024] When the occupant 200 has a large weight and body size, the hardness adjustment mechanism 3 can rotate about the central axis of the first flexible member 31 to adjust the size ratio of the first flexible member 31 and the second flexible member 32 along the height direction of the seat assembly 100 to increase. Since the hardness of the second flexible member 32 is greater than that of the first flexible member 31, this adjustment can make the flexible seat cushion 2 feel softer and improve the comfort of the occupant 200.

[0025] When the occupant 200 is relatively small in weight and size, the stiffness adjustment mechanism 3 can rotate about the central axis of the first flexible member 31 to adjust the size ratio of the first flexible member 31 to the second flexible member 32 along the height direction of the seat assembly 100 to become smaller. Since the stiffness of the second flexible member 32 is greater than that of the first flexible member 31, this adjustment can make the flexible seat cushion 2 more supportive, reduce the risk of the small-weight or small-sized occupant 200 sinking, and the small-weight and small-sized occupant 200 will have less pressure on the flexible seat cushion 2 and will not directly feel the second flexible member 32. This can improve the safety of the vehicle while taking into account comfort.

[0026] Therefore, the first flexible member 31 and the second flexible member 32 can be adjusted according to the weight and body shape of the occupant 200, so that the stiffness adjustment mechanism 3 can effectively support the occupant 200, reduce the risk of occupants 200 of different weights and body shapes falling, and improve the safety and comfort of the vehicle.

[0027] In some examples of the present invention, such as Figure 1As shown, the seat frame 11 defines a first receiving groove 111 that opens toward the flexible seat cushion 2. The first receiving groove 111 is used to receive part of the structure of the hardness adjustment mechanism 3. The flexible seat cushion 2 defines a second receiving groove 21 that opens toward the seat frame 1. The second receiving groove 21 is used to receive another part of the structure of the hardness adjustment mechanism 3.

[0028] The seat cushion frame 11 defines a first receiving groove 111, which opens toward the flexible seat cushion 2. The first receiving groove 111 is used to receive part of the structure of the hardness adjustment mechanism 3. The flexible seat cushion 2 defines a second receiving groove 21, which opens toward the seat frame 1. The second receiving groove 21 is used to receive another part of the structure of the hardness adjustment mechanism 3. This arrangement allows the entire hardness adjustment mechanism 3 to be received between the seat cushion frame 11 and the flexible seat cushion 2, which is beneficial to the close fit between the seat cushion frame 11 and the flexible seat cushion 2, reduces the risk of gaps between the seat cushion frame 11 and the flexible seat cushion 2, and thus improves the riding stability and comfort of the occupant 200.

[0029] In some examples of the present invention, such as Figure 1 As shown, the volume of the first receiving slot 111 is A, and the volume of the second receiving slot 21 is B, satisfying the relationship: 0.95≤A / B≤1.05.

[0030] The volume of the first receiving slot 111 is A, and the volume of the second receiving slot 21 is B. The volume A of the first receiving slot 111 and the volume B of the second receiving slot 21 satisfy the relationship: 0.95 ≤ A / B ≤ 1.05. That is, the ratio between the volume A of the first receiving slot 111 and the volume B of the second receiving slot 21 is between 0.95 and 1.05. For example, the ratio between the volume A of the first receiving slot 111 and the volume B of the second receiving slot 21 can be 0.95, 1, or 1.0. 5. However, this application is not limited to this. As long as the ratio between the volume A of the first receiving groove 111 and the volume B of the second receiving groove 21 is between 0.95 and 1.05, this setting can make the volume of the first receiving groove 111 and the volume of the second receiving groove 21 reasonable, reduce the risk that the adjustment support effect of the hardness adjustment mechanism 3 will be poor due to the ratio being too large, and also reduce the risk that the occupant 200 will directly feel the second flexible part 32 due to the ratio being too small, thereby reducing the risk of the comfort of the seat assembly 100 being reduced.

[0031] In some examples of the present invention, such as Figure 1 As shown, the hardness of the second flexible member 32 is greater than that of the first flexible member 31.

[0032] The second flexible element 32 has a higher hardness than the first flexible element 31. When the occupant 200 has a larger weight and body size, the hardness adjustment mechanism 3 can rotate around the central axis of the first flexible element 31 to adjust the size ratio of the first flexible element 31 and the second flexible element 32 along the height direction of the seat assembly 100 to increase. Since the second flexible element 32 has a higher hardness than the first flexible element 31, this adjustment can make the flexible seat cushion 2 feel softer and improve the comfort of the occupant 200.

[0033] When the occupant 200 is relatively small in weight and size, the stiffness adjustment mechanism 3 can rotate about the central axis of the first flexible member 31 to adjust the size ratio of the first flexible member 31 to the second flexible member 32 along the height direction of the seat assembly 100 to become smaller. Since the stiffness of the second flexible member 32 is greater than that of the first flexible member 31, this adjustment can make the flexible seat cushion 2 more supportive, reduce the risk of the small-weight or small-sized occupant 200 sinking, and the small-weight and small-sized occupant 200 will have less pressure on the flexible seat cushion 2 and will not directly feel the second flexible member 32. This can improve the safety of the vehicle while taking into account comfort.

[0034] In some examples of the present invention, such as Figure 1 As shown, the seat assembly 100 may further include: a drive component, which is disposed on the seat cushion frame 11 and is connected to the hardness adjustment mechanism 3 in a transmission manner, and the drive component is configured to drive the hardness adjustment mechanism 3 to rotate.

[0035] The seat assembly 100 may further include a drive component. In some embodiments of this application, the drive component may be configured as a motor. In some embodiments of this application, the drive component may be configured as a cylinder. The drive component is disposed on the seat cushion frame 11, and its output end is connected to the hardness adjustment mechanism 3 for transmission, so that the drive component can drive the hardness adjustment mechanism 3 to rotate, thereby smoothly adjusting the dimensional ratio of the first flexible member 31 and the second flexible member 32 along the height direction of the seat assembly 100. This allows the hardness adjustment mechanism 3 to effectively support the occupant 200, reducing the risk of occupants 200 of different weights and body types falling over, and improving the safety and comfort of the vehicle.

[0036] In some examples of the present invention, such as Figure 1 As shown, the seat assembly 100 may also include: a controller, a seat belt pull-out sensor 4, the controller, the seat belt pull-out sensor 4, and a drive unit. The controller is configured to control the drive unit to drive the stiffness adjustment mechanism 3 to rotate according to the seat belt 41 pull-out size information, so as to adjust the size ratio of the first flexible member 31 and the second flexible member 32 along the height direction of the seat assembly 100. The size ratio of the first flexible member 31 is proportional to the extension size of the seat belt 41.

[0037] The seat assembly 100 may further include a controller and a seatbelt pull-out sensor 4. The controller, seatbelt pull-out sensor 4, and drive unit are all communicatively connected. In some embodiments of this application, the controller, seatbelt pull-out sensor 4, and drive unit are all connected via WLAN. In some embodiments of this application, the controller, seatbelt pull-out sensor 4, and drive unit are all connected via Bluetooth.

[0038] The controller can receive the seat belt 41 pull-out size information and control the drive component to drive the stiffness adjustment mechanism 3 to rotate according to the seat belt 41 pull-out size information, so as to adjust the size ratio of the first flexible member 31 and the second flexible member 32 along the height direction of the seat assembly 100 for different body types of occupants 200. The size ratio of the first flexible member 31 is directly proportional to the seat belt 41 extension size. When the seat belt 41 extension size is longer, the occupant 200 is larger; when the seat belt 41 extension size is shorter, the occupant 200 is smaller. In this way, the seat support can be adjusted for different body types of occupants 200, improving the safety of occupants 200 while also taking into account their comfort.

[0039] In some examples of the present invention, such as Figure 1 As shown, the seat assembly 100 may further include: a weight sensor, which is located on the flexible seat cushion 2 and connected to the controller. The controller is also configured to control the drive component to drive the hardness adjustment mechanism 3 to rotate according to the load information, so as to adjust the size ratio of the first flexible element 31 and the second flexible element 32 along the height direction of the seat assembly 100. The size ratio of the first flexible element 31 is proportional to the load of the flexible seat cushion 2.

[0040] The seat assembly 100 may also include a weight sensor, which is located on the flexible seat cushion 2 and is connected to a controller. The controller can receive the load information from the weight sensor and, based on the load information, control the drive component to drive the hardness adjustment mechanism 3 to rotate. This allows for the adjustment of the size ratio of the first flexible component 31 and the second flexible component 32 along the height direction of the seat assembly 100 for occupants of different body types 200. The size ratio of the first flexible component 31 is directly proportional to the load-bearing capacity of the flexible seat cushion 2. The higher the load information value, the greater the weight of the occupant 200; the lower the load information value, the smaller the weight of the occupant 200. This allows for the adjustment of the seat support for occupants of different weights, improving both the safety and comfort of the occupants 200.

[0041] In some examples of the present invention, such as Figure 1 As shown, according to the formula: Calculate the size proportion of the first flexible component 31, where Q is the size proportion of the first flexible component 31. The load-bearing weight of the weight sensor; The reference load-bearing weight; This refers to the seatbelt pull-out amount of 41. The standard seatbelt pull-out amount is 41.

[0042] In some embodiments of this application, based on the HⅢ50th dummy in a car collision as a reference, its weight is the reference occupant weight 200, and the amount of seat belt 41 pulled out by the dummy is the reference seat belt 41 pull-out amount. The dummy's load-bearing information serves as the baseline load capacity. The occupants pulled out 41 seat belts out of 200 people. The load-bearing information for occupant 200 is the load-bearing weight of the weight sensor. According to the formula: The size ratio of the first flexible member 31 is calculated so that the drive stiffness adjustment mechanism 3 rotates to the position where the size ratio of the first flexible member 31 to the second flexible member 32 along the height direction of the seat assembly 100 is most suitable, thereby improving the safety of the passenger 200 while also taking into account the comfort of the passenger 200.

[0043] In some examples of the present invention, such as Figure 1 As shown, the first flexible component 31 is made of the same material as the flexible seat cushion 2.

[0044] The first flexible component 31 is made of the same material as the flexible seat cushion 2. This arrangement makes the material design of the first flexible component 31 and the flexible seat cushion 2 reasonable, effectively reducing the foreign body sensation when the passenger 200 sits on the seat, thereby improving the passenger 200's riding comfort.

[0045] The vehicle according to the present invention includes a seat assembly 100 of the vehicle described in the above embodiment. The first flexible member 31 and the second flexible member 32 can be adjusted according to the weight and body shape of the occupant 200, so that the stiffness adjustment mechanism 3 can effectively support the occupant 200, reduce the risk of occupants 200 of different weights and body shapes falling, and improve the safety and comfort of the vehicle.

[0046] The ratio of the dimensions of the first flexible member 31 and the second flexible member 32 along the height direction of the seat assembly 100 is adaptively adjusted according to the different weight and body shape of the occupant 200, so as to combine safety and comfort. Before a collision occurs, the occupant 200's descent protection and comfort are taken into consideration, thus preventing problems before they occur. At the same time, the seat assembly 100's descent protection is adjusted before the vehicle collision, reducing the risk of not being able to recognize the trigger signal.
