[0027] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. Below, reference is made to Figures 1 - 4 Describe the seat frame 100 according to an embodiment of the present utility model, including: a seat cushion frame 10, a sliding assembly 20, and a connecting rod assembly 30.

[0028] Specifically, as Figure 1 and Figure 2 shown, the seat cushion frame 10 is disposed on the sliding assembly 20; the connecting rod assembly 30 includes a first connecting rod 31 and a second connecting rod 32. One end of the first connecting rod 31 is rotatably connected to the seat cushion frame 10, one end of the second connecting rod 32 is rotatably connected to the sliding assembly 20, and the other ends of the first connecting rod 31 and the second connecting rod 32 are rotatably and movably connected.

[0029] The seat cushion frame 10 is connected to the sliding assembly 20 through the connecting rod assembly 30. Among them, the sliding assembly 20 includes: a slider 21 and a slide rail 22. The slider 21 is installed on the slide rail 22, and the slider 21 can move relative to the slide rail 22. The seat cushion frame 10 is connected to the slider 21 through the connecting rod assembly 30. The seat frame 100 further includes a driving assembly, and the driving assembly is disposed between the sliding assembly 20 and the seat cushion frame 10, and the driving assembly is connected to the second connecting rod 32. All connections between the seat cushion frame 10, the first connecting rod 31, the second connecting rod 32, and the sliding assembly 20 are rotational connections.

[0030] The driving component can be used to adjust the angle of the seat cushion frame 10 to meet the needs of different occupants. The other end of the first link 31 is rotatably and movably connected to the other end of the second link 32, so that the first link 31 rotates relative to the second link 32, and at the same time, the first link 31 rotates relative to the seat cushion frame 10. That is, the seat cushion frame 10 rotates relative to the sliding component 20 through the link assembly 30 to adjust the angle of the seat cushion frame 10 relative to the sliding component 20. When a vehicle collision occurs, the seat cushion frame 10 is stressed. Since the connection between the first link 31 and the second link 32 is rotatable and movable, when the seat cushion frame 10 is stressed and transmits the force to the first link 31, relative rotation and relative movement occur between the first link 31 and the second link 32, so that the second link 32 can move along the length direction of the first link 31 towards the end of the first link 31 away from the second link 32. That is, the first link 31 absorbs energy by deforming.

[0031] According to the seat frame 100 of the embodiment of the present invention, through the rotatable and movable connection between the first link 31 connected to the seat cushion frame 10 and the second link 32 connected to the sliding component 20, during a vehicle collision, relative rotation and movement can occur between the first link 31 and the second link 32, so that through the movement between the first link 31 and the second link 32 during a collision, the collapse of the seat cushion frame 10 is realized to reduce the stress on the lumbar spine of the occupant, increase the protection for the occupant, and avoid the occupant being impacted by inertia due to the inability to adjust the angle of the seat cushion frame 10 in time.

[0032] According to some embodiments of the present invention, as Figure 2 shown, a through hole 311 is formed in the first link 31. The through hole 311 penetrates the first link 31 along the thickness direction of the first link 31 and extends along the length direction of the first link 31.

[0033] That is, a through hole 311 is formed by penetrating the first link 31 from one side of the first link 31 towards the other side of the first link 31 along the thickness direction of the first link 31 at the end of the first link 31 adjacent to the second link 32. The through hole 311 extends along the length direction of the first link 31 and is disposed adjacent to the end of the first link 31 where the first link 31 is connected to the second link 32.

[0034] Accordingly, a through hole 311 is formed in the first link 31. The through hole 311 is a deformable energy-absorbing hole. When impacted and the driving component fails, it can enable the second link 32 to move within the through hole 311 of the first link 31, changing the relative position between the first link 31 and the second link 32, and achieving the adjustment of the angle of the seat cushion frame 10. At the same time, the setting of the through hole 311 can reduce the possibility of the collision force causing deformation of the link assembly 30 during transmission between the first link 31 and the second link 32, avoid breakage of the first link 31, better protect the lumbar spine of vehicle occupants, and improve the safety of the seat frame 100.

[0035] According to some embodiments of the present invention, as Figure 2 shown, a first mounting hole is formed at one end of the first link 31. The fastener 312 is adapted to pass through the first mounting hole and connect with the seat cushion frame 10. The first link 31 is rotatable relative to the fastener 312.

[0036] A first mounting hole is formed at one end of the first link 31 adjacent to the seat cushion frame 10. The first mounting hole penetrates the first link 31 along the thickness direction of the first link 31, enabling the fastener 312 to pass through the first mounting hole and be fixed on the seat cushion frame 10. The first link 31 and the fastener 312 form a clearance fit, enabling the first link 31 to be rotatably connected to the seat cushion frame 10, thereby facilitating the adjustment of the angle of the seat cushion frame 10.

[0037] Accordingly, the first link 31 is rotatable relative to the fastener 312, that is, the first link 31 is rotatably connected to the seat cushion frame 10. When a vehicle collision occurs, by setting the fastener 312 to connect the first link 31 and the seat cushion frame 10, the seat cushion frame 10 can automatically follow the first link 31 to timely adjust the height of the seat cushion frame 10, and at the same time prevent the first link 31 from detaching from the seat cushion frame 10.

[0038] In this embodiment, the fastener 312 can be a pin or a shaft pin.

[0039] According to some embodiments of the present invention, as Figure 2 shown, the first mounting hole and the through hole 311 are arranged at intervals.

[0040] That is, the first mounting hole and the through hole 311 are arranged at intervals along the length direction of the first link 31 on the first link 31. Accordingly, the first mounting hole and the through hole 311 are arranged at intervals, avoiding the connection between the first mounting hole and the first link 31, resulting in stress concentration on the first link 31, improving the anti-bending ability of the first link 31, enhancing the structural strength of the first link 31, facilitating the transmission of the collision force between the seat cushion frame 10 and the first link 31, and being beneficial to the adjustment of the angle of the seat cushion frame 10.

[0041] According to some embodiments of the present invention, asFigure 4 As shown, on the other end of the first link 31, i.e., the end connected to the second link 32, a second mounting hole 313 is formed. The second mounting hole 313 cooperates with the second link 32, and the second mounting hole 313 is spaced from the through hole 311; or the second mounting hole 313 communicates with the through hole 311.

[0042] That is, on the other end of the first link 31 adjacent to the second link 32, the second mounting hole 313 is formed by penetrating the first link 31 from one side to the other side in the thickness direction of the first link 31. The second mounting hole 313 cooperates with the second link 32. When the vehicle is impacted, the other end of the first link 31 and the other end of the second link 32 can be rotatably and movably connected quickly, that is, it is convenient for the first link 31 and the second link 32 to be rotatably connected and movably connected at the same time, which is convenient for energy absorption by using the deformation of the through hole 311, quickly adjusting the height of the seat cushion frame 10, and reducing the impact on the lumbar spine of the occupant.

[0043] Optionally, in this embodiment, the second mounting hole 313 and the through hole 311 are spaced along the length direction of the first link 31, or the second mounting hole 313 communicates with the through hole 311, so that when the occupant is stressed and the driving component cannot adjust the angle in time, the second link 32 can move from cooperating with the second mounting hole 313 to cooperating with the through hole 311 in the through hole 311 through the deformation of the through hole 311 to achieve energy absorption and thus achieve the angle adjustment of the seat cushion frame 10, reducing the force on the occupant.

[0044] In this embodiment, the second mounting hole 313 and the through hole 311 are spaced along the length direction of the first link 31 adjacent to the other end of the second link 32 away from the first link 31, and at the same time the second mounting hole 313 communicates with the through hole 311. For example, an opening is formed on the side wall of the second mounting hole 313, and the opening faces the through hole 311, and the through hole 311 communicates with the second mounting hole 313 through the opening. Thus, the second mounting hole 313 communicates with the through hole 311, so that after the occupant is impacted by the inertial force, the second link 32 can quickly slide from the second mounting hole 313 into the through hole 311, and part of the impact force is absorbed through the deformation of the first link 31, reducing the impact force on the occupant to better protect the safety of the occupant.

[0045] According to some embodiments of the present invention, as Figure 4 shown, the first link 31 further includes: a plurality of bosses 33. The plurality of bosses 33 include a first boss and a second boss. The first boss is provided at one end of the first link 31, i.e., the end of the first link 31 adjacent to the seat cushion frame 10, and the first boss is formed with a first mounting hole; or the second boss is provided at the other end of the first link 31 connected to the second link 32, and the second boss is formed with the second mounting hole 313, or the first boss is formed with a first mounting hole, and at the same time the second boss is formed with the second mounting hole 313.

[0046] In this embodiment, the plurality of bosses 33 include a first boss and a second boss. The first boss is connected to one end of the first connecting rod 31 adjacent to the seat cushion frame 10, and a first mounting hole is formed on the first boss. Alternatively, the second boss is connected to the other end of the first connecting rod 31 connecting the second connecting rod 32, and a second mounting hole 313 is formed on the second boss. Optionally, the first boss is connected to one end of the first connecting rod 31 adjacent to the seat cushion frame 10, a first mounting hole is formed on the first boss, and at the same time, the second boss is connected to the other end of the first connecting rod 31 connecting the second connecting rod 32, and a second mounting hole 313 is formed on the second boss.

[0047] Thus, a first boss is provided at one end of the first connecting rod 31 adjacent to the seat cushion frame 10, and a first mounting hole is formed on the first boss. At the same time, a second boss is provided at the other end of the first connecting rod 31 connected to the second connecting rod 32, and a second mounting hole 313 is formed on the second boss, which can improve the positioning accuracy and connection strength of the second connecting rod 32 on the first connecting rod 31, and prevent the other end of the second connecting rod 32 from falling off from the first mounting hole or the second mounting hole 313 when the other end of the first connecting rod 31 and the other end of the second connecting rod 32 move relative to each other, improve the structural strength of the connection between the first connecting rod 31 and the seat cushion frame 10, and improve the structural strength of the connection between the first connecting rod 31 and the second connecting rod 32, and prevent the first connecting rod 31 from being bent in the thickness direction under force. At the same time, due to the arrangement of the plurality of bosses 33, the contact area between the first connecting rod 31 and the seat cushion frame 10 is increased, and the contact area between the first connecting rod 31 and the second connecting rod 32 is increased, so that the connection between the first connecting rod 31 and the second connecting rod 32 is more stable and not easily deformed by torsion under force.

[0048] According to some embodiments of the present invention, as Figure 2 and Figure 4 shown, along the direction from the end of the first connecting rod 31 connected to the seat cushion frame 10 to the other end of the second connecting rod 32, the cross-sectional area of the through hole 311 shows an increasing trend.

[0049] Along the length direction of the first connecting rod 31, from the end of the first connecting rod 31 adjacent to the seat cushion frame 10 towards the other end of the first connecting rod 31 adjacent to the second connecting rod 32, the cross-sectional area of the through hole 311 gradually increases.

[0050] In this embodiment, the second link 32 has a first position and a second position adjacent to the other end of the first link 31. Among them, the second link 32 is in the first position in cooperation with the second mounting hole 313, and the second link 32 is in the second position in cooperation with the through hole 311. When the vehicle is in normal use, the first link 31 and the second link 32 are connected in the first position, that is, when the driving assembly drives the link assembly 30 to move at this time, the adjustment of the height and angle of the seat cushion frame 10 can be realized. When the vehicle is impacted and the driving assembly fails due to the inertial force, the through hole 311 is deformed and the first link 31 and the second link 32 are connected in the second position.

[0051] Therefore, when the vehicle is collided, the second link 32 and the first link 31 change from the first position to the second position connection. Along the direction from the end of the first link 31 adjacent to the seat cushion frame 10 to the end of the second link 32 adjacent to the other end, the cross-sectional area of the through hole 311 gradually increases, which can facilitate the second link 32 to smoothly cooperate with the through hole 311 and increase the guiding effect on the second link 32. And the through hole 311 can absorb the impact force transmitted from the seat cushion frame 10 to the first link 31, and realize the slow adjustment of the angle of the seat cushion frame 10 relative to the sliding assembly 20, reduce the thrust of the seat cushion frame 10 on the lumbar vertebra of the vehicle occupant, and effectively improve the safety of the seat frame 100.

[0052] According to some embodiments of the present invention, such as Figure 2 and Figure 4 shown, the first link 31 is provided with a flange, the flange is arranged on the outer peripheral edge of the first link 31, and the flange extends along the thickness direction of the first link 31.

[0053] That is, the outer peripheral edge of the first link 31 is provided with a flange along the thickness direction of the first link 31 toward the second link 32. Thus, the outer peripheral edge of the first link 31 is provided with a flange, which can improve the structural strength of the first link 31. When the first link 31 rotates and moves relative to the second link 32, the anti-torsion ability of the first link 31 can be improved, and the first link 31 can be prevented from deforming or even breaking, and the link assembly 30 can be prevented from failing.

[0054] According to some embodiments of the present invention, the seat cushion frame 10 further includes: a stop portion, and the stop portion is arranged on at least one side of the first link 31 along the width direction of the first link 31.

[0055] That is, at one end where the first link 31 is connected to the seat cushion frame 10, a stop portion is provided on at least one side along the width direction of the first link 31. Thus, the stop portion is provided on at least one side of the first link 31 along the width direction of the first link 31. After the through hole 311 is deformed and absorbs energy, the stop portion can prevent the end of the first link 31 connected to the seat cushion frame 10 from coming into direct contact with the seat cushion frame 10 on the side facing the seat cushion frame 10 along the width direction of the first link 31, provide a supporting effect for the first link 31, and improve the structural strength of the link assembly 30.

[0056] According to some embodiments of the present invention, as Figure 4 shown, the other end of the second link 32 connected to the first link 31 forms a limiting groove, and the other end of the first link 31 away from the seat cushion frame 10 cooperates with the limiting groove. That is, a limiting groove is formed at one end of the second link 32 connected to the first link 31. The limiting groove extends along the circumferential direction of the second link 32, and the limiting groove cooperates with the second mounting hole 313 so that the first link 31 can rotate in the limiting groove.

[0057] Thus, the other end of the first link 31 cooperates with the limiting groove formed at the other end of the second link 32. When the vehicle collides, the driving assembly drives the second link 32 to cooperate with the limiting groove formed at the other end of the second link 32 through the boss 33 at the other end of the first link 31, so that the first link 31 rotates relative to the limiting groove, preventing the boss 33 at the other end of the first link 31 from separating from the other end of the second link 32, further improving the connection strength between the other end of the first link 31 and the other end of the second link 32, and effectively realizing the adjustment of the angle of the seat cushion frame 10 relative to the sliding assembly 20. At the same time, the limiting groove can limit the first link 31 in the length direction of the second link 32, that is, the thickness direction of the first link 31, and prevent the movement of the first link 31 in the length direction of the second link 32 when the first link 31 is connected to the second link 32, effectively reducing the possibility of torsional deformation of the first link 31 under force.

[0058] The seat according to the second aspect embodiment of the present invention includes the seat frame 100 according to the first aspect embodiment of the present invention above.

[0059] According to the seat of the embodiment of the present invention, by providing the through hole 311 on the link assembly 30, when the strength of the driving assembly is insufficient or fails, the deformation of the through hole 311 when the first link 31 is connected to the second link 32 increases the energy absorption effect of the seat, reduces the magnitude of the lumbar force transmitted to the occupant, increases the protection of the occupant, and improves the safety of the seat.
