[0028] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the 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 by referring to the drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0029] Reference is made below to Figures 1 - 3Describe a seat assembly 10 for a vehicle according to an embodiment of the present application. The seat assembly 10 includes a seat frame 11. The seat frame 11 includes a connecting portion 111 and a supporting portion 112. The supporting portion 112 is disposed on both sides of the connecting portion 111 and is integrally formed with the connecting portion 111. A first energy absorption groove 113 and a second energy absorption groove 114 extending inward are formed on the supporting portion 112. The first energy absorption groove 113 extends in a first direction, and the second energy absorption groove 114 extends in a second direction. The first direction intersects with the second direction.

[0030] Currently, the rear seat frame structure of a vehicle usually adopts an EPP (polypropylene plastic foam material) and steel wire frame structure. The foam is connected and formed with the overall EPP steel wire frame through a covering. While using high-strength EPP to replace part of the steel wire and foam to meet the requirements of the anti-submergence and trunk impact high-strength tests and achieve lightweight at the same time, however, there will be a shrinkage problem after the EPP seat frame is injection-molded. After the EPP shrinks, it will cause the steel wire frame to bend, affecting the use of the seat frame.

[0031] As Figure 1 shown, specifically, the seat assembly 10 may include a seat frame 11 and a foam member. The foam member may be disposed on the outer periphery of the seat frame 11 and connected to the seat frame 11. The seat frame 11 may include a connecting portion 111 and a supporting portion 112. The supporting portion 112 may be disposed on both sides of the connecting portion 111, and the supporting portion 112 can be integrally formed with the connecting portion 111. In a specific embodiment, the supporting portion 112 may be configured as two, and the two supporting portions 112 may be respectively located on both sides of the connecting portion 111.

[0032] Furthermore, energy absorption grooves may be formed on the supporting portion 112. The energy absorption grooves may be recessed inwardly towards the inside of the supporting portion 112. Among them, the energy absorption grooves may include a first energy absorption groove 113 and a second energy absorption groove 114. The first energy absorption groove 113 can extend in a first direction, and the second energy absorption groove 114 can extend in a second direction. It should be noted that the energy absorption grooves can provide a part of the shrinkage space for the shrinkage of the supporting portion 112, thereby ensuring that the overall deformation amount of the supporting portion 112 is reduced and avoiding the bending deformation of the internal frame structure. Thus, the energy absorption grooves can play a role in crash energy absorption. The first direction may intersect with the second direction, so as to ensure that the extending directions of the first energy absorption groove 113 and the second energy absorption groove 114 are different, which is beneficial for the seat frame 11 to achieve shrinkage through the first energy absorption groove 113 and the second energy absorption groove 114, reducing the deformation amount of the seat frame 11.

[0033] Briefly, the seat assembly 10 of the embodiments of the present application has a seat frame 11. The seat frame 11 includes a connecting portion 111 and a supporting portion 112. The supporting portion 112 may be provided with a first energy absorption groove 113 and a second energy absorption groove 114, and the extending directions of the first energy absorption groove 113 and the second energy absorption groove 114 are different. When the seat frame 11 contracts, it can contract towards the first energy absorption groove 113 and the second energy absorption groove 114. Therefore, the first energy absorption groove 113 and the second energy absorption groove 114 can play a role in collapse energy absorption, while reducing the deformation amount of the seat frame 11 and improving the reliability of the seat assembly 10.

[0034] In some embodiments of the present application, the first direction may be orthogonal to the second direction. By making the first direction orthogonal to the second direction, the seat frame 11 can contract towards the first energy absorption groove 113 and the second energy absorption groove 114 when contracting. In a specific embodiment, the first direction may be the width direction of the vehicle, that is, the Y direction of the vehicle, and the second direction may be the length direction of the vehicle, that is, the X direction of the vehicle.

[0035] As Figure 1 shown, in some embodiments of the present application, a first weight reduction hole 1121 may also be formed on the supporting portion 112. The first weight reduction hole 1121 can penetrate through the supporting portion 112 in the thickness direction. The first weight reduction hole 1121 can play a role in weight reduction, thereby reducing the overall weight of the supporting portion 112 and realizing the lightweight design of the seat assembly 10. In some embodiments, the first weight reduction hole 1121 may be configured as a square hole. A second weight reduction hole 1122 may also be formed on the seat frame 11. The second weight reduction hole 1122 can be arranged to surround the seat assembly 10 in the circumferential direction. The second weight reduction hole 1122 can further reduce the overall weight of the seat assembly 10 to realize the lightweight design of the seat assembly 10.

[0036] As Figure 1 shown, in some embodiments of the present application, a plurality of first energy absorption grooves 113 may be configured, and the plurality of first energy absorption grooves 113 may be respectively located on both sides of the first weight reduction hole 1121. It should be noted that the plurality of first energy absorption grooves 113 may be provided on both sides of the first weight reduction hole 1121 in the first direction. The second energy absorption groove 114 may be configured as a plurality, and the plurality of second energy absorption grooves 114 may be configured to be spaced apart in the first direction. The first energy absorption groove 113 and the second energy absorption groove 114 do not intersect. The second energy absorption groove 114 may be located on one side or both sides of the weight reduction hole in the second direction. Using a plurality of first energy absorption grooves 113 and a plurality of second energy absorption grooves 114 can further reduce the deformation amount of the seat frame 11.

[0037] In some embodiments of the present application, the difference between the thickness of the support portion 112 and the depth of the first energy-absorbing groove 113 is d1, which satisfies the relational expression: 30 mm ≤ d1 ≤ 50 mm. That is, the difference between the thickness of the support portion 112 and the depth of the first energy-absorbing groove 113 can be any value between 30 mm and 50 mm. For example, the difference between the thickness of the support portion 112 and the depth of the first energy-absorbing groove 113 can be, but is not limited to, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, etc. Such a setting ensures that the first energy-absorbing groove 113 can effectively collapse and absorb energy.

[0038] The difference between the thickness of the support portion 112 and the depth of the second energy-absorbing groove 114 is d2, which satisfies the relational expression: 30 mm ≤ d2 ≤ 50 mm. That is, the difference between the thickness of the support portion 112 and the depth of the second energy-absorbing groove 114 can be any value between 30 mm and 50 mm. For example, the difference between the thickness of the support portion 112 and the depth of the second energy-absorbing groove 114 can be, but is not limited to, 30 mm, 40 mm, 50 mm, etc. Such a setting ensures that the second energy-absorbing groove 114 can effectively collapse and absorb energy.

[0039] As Figure 2 shown, in some embodiments of the present application, the seat assembly 10 may further include a reinforcement assembly 12. The reinforcement assembly 12 may be disposed inside the seat frame 11, and the reinforcement assembly 12 may include a first side beam 121 and a second side beam 122. The second side beam 122 may be configured as multiple, and the multiple second side beams 122 may be spaced apart in the first direction. The first side beam 121 may be disposed at both ends of the multiple second side beams 122 in the second direction, and the first side beam 121 can be connected to the multiple second side beams 122 to form a closed structure. The reinforcement assembly 12 can improve the overall strength of the seat frame 11, and the reinforcement assembly 12 can also be used to connect the vehicle body and the foam structure.

[0040] Furthermore, the reinforcement component 12 may further include a first reinforcement beam 123 and a second reinforcement beam 124. The first reinforcement beam 123 may be disposed on a side of the first side beam 121 away from the second side beam 122, and the first reinforcement beam 123 can be connected to the first side beam 121. Among them, the first reinforcement beam 123 may be configured as multiple, and the multiple first reinforcement beams 123 may be spaced apart in the first direction. The multiple first reinforcement beams 123 can be arranged in one-to-one correspondence with the connecting portion 111 and the supporting portion 112. By providing multiple first reinforcement beams 123, the overall strength of the reinforcement component 12 can be improved, and the problem of deformation of the reinforcement component 12 when the seat frame 11 collapses can be prevented. The second reinforcement beam 124 may extend in the second direction, and one end of the second reinforcement beam 124 can be connected to the first side beam 121, and the other end of the second reinforcement beam 124 can be connected to the second side beam 122. The second reinforcement beam 124 may also be configured as multiple, and the use of multiple second reinforcement beams 124 further improves the overall strength of the reinforcement component 12, avoids the problem of bending deformation of the reinforcement component 12, and improves the service life of the seat component 10.

[0041] As Figure 3 shown, in some embodiments of the present application, the supporting portion 112 may further include a first block 1123 and a second block 1124. The first block 1123 and the second block 1124 may be configured as an integrally formed part, and a first energy absorption groove 113 may be formed at the connection between the first block 1123 and the second block 1124. The included angle between the extending direction of the first block 1123 and the extending direction of the second block 1124 is α, satisfying the relational expression: 2° ≤ α ≤ 4°, that is, the included angle between the extending direction of the first block 1123 and the extending direction of the second block 1124 may be any value between 2° and 4°. For example, the included angle between the extending direction of the first block 1123 and the extending direction of the second block 1124 may be, but not limited to, 2°, 3°, 4°, etc. Since the supporting portion 112 will undergo deformation in the thickness direction, setting an included angle between the extending direction of the first block 1123 and the extending direction of the second block 1124 can reserve space for the deformation of the supporting portion 112, so that the supporting portion 112 remains horizontal after collapse.

[0042] The vehicle of the embodiment of the present application will be briefly described below.

[0043] The vehicle according to the embodiment of the present application is provided with the seat assembly 10 of the above embodiment. Since the vehicle according to the embodiment of the present application is provided with the seat assembly 10 of the above embodiment, therefore, the seat assembly 10 of this vehicle has a seat frame 11, the seat frame 11 includes a connecting portion 111 and a supporting portion 112, a first energy absorption groove 113 and a second energy absorption groove 114 can be provided on the supporting portion 112, and the extending directions of the first energy absorption groove 113 and the second energy absorption groove 114 are different. When the seat frame 11 contracts, it can contract towards the first energy absorption groove 113 and the second energy absorption groove 114. Therefore, the first energy absorption groove 113 and the second energy absorption groove 114 can play a role in crash energy absorption, while reducing the deformation amount of the seat frame 11, improving the reliability of the seat assembly 10, and meeting the user's needs.
