DETAILED DESCRIPTION

[0025] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] The zero-gravity seat frame mechanism according to the first embodiment of the present invention includes a seat cushion frame 10 and a backrest frame 11, and also includes: an adjustment device, the adjustment device is located at the lower part of the seat cushion frame 10; an adjustment device, used to adjust the height of the seat cushion frame 10 to reduce the angle between the seat cushion frame 10 and the backrest frame 11 in the zero-gravity state.

[0029] According to the zero-gravity seat frame mechanism of the embodiment of the present application, an adjustment device is introduced to reduce the angle between the seat cushion frame 10 and the backrest frame 11 in the zero-gravity state, thereby reducing the angle between the occupant's upper torso and lower limbs, so as to achieve a self-locking state between the safety belt and the occupant's ilium, slowing down the tendency of the safety belt to slide toward the occupant's abdomen, and reducing abdominal injuries.

[0030] Specifically, if Figure 1 As shown, when the seat is in a normal state, the angle between the seat cushion frame 10 and the backrest frame 11 is generally in the range of 90°-110°. In a normal state, the ilium of the passenger's waist is generally upright, and the ilium of the passenger and the safety belt fit tightly. Figure 2As shown, when the seat is in a zero-gravity state, the angle between the seat cushion frame 10 and the backrest frame 11 is generally greater than 110°. In the zero-gravity state, the ilium of the occupant's waist turns from an upright state to a tilted state, and the angle between the safety belt and the ilium will increase. The friction between the two will decrease accordingly, which cannot meet the self-locking requirements. Self-locking refers to a mechanism that uses friction to fix or lock an object. In this application, it refers to the state where the safety belt and the human body's ilium reach a non-slip state through friction. When a collision occurs, generally a head-on collision, the occupant will move forward and increase the rotation of the upper torso. Since the angle between the seat cushion frame 10 and the backrest frame 11 remains unchanged, the movement of the occupant during a collision increases the risk of the occupant diving. The safety belt will slide from the ilium of the occupant to the abdomen of the occupant, causing additional damage to the occupant's abdomen. The zero-gravity seat frame mechanism of the embodiment of the present application, such as Figure 3 As shown, when a collision occurs, an adjustment device is introduced to reduce the angle between the seat cushion frame 10 and the backrest frame 11 in a zero-gravity state, thereby reducing the angle between the occupant's upper torso and lower limbs, so as to achieve a self-locking state between the safety belt and the occupant's ilium, thereby slowing down the tendency of the safety belt to slide toward the occupant's abdomen in a collision and reducing the injury to the occupant's abdomen.

[0031] According to some embodiments of the present invention, the adjustment device includes: a connecting rod assembly, connecting the base 13 and the seat cushion frame 10 of the seat, and located between the base 13 and the seat cushion frame 10; a driving member 12, connected to the connecting rod assembly, for driving the connecting rod assembly to move to adjust the angle between the seat cushion frame 10 and the backrest frame 11.

[0032] Specifically, through the combination of the connecting rod assembly and the driving member 12, the precise control of the mechanical structure of the adjustment device is achieved. In the event of a collision, the connecting rod assembly driven by the motor can respond quickly to reduce the angle between the seat cushion frame 10 and the backrest frame 11 in the zero-gravity state, thereby reducing the injury to the occupant's abdomen. According to some embodiments of the present invention, the connecting rod assembly includes a first connecting rod 14 and a second connecting rod 15, one end of the first connecting rod 14 is rotatably connected to one end of the second connecting rod 15, the other end of the first connecting rod 14 is rotatably connected to the base 13, and the other end of the second connecting rod 15 is rotatably connected to the seat cushion frame 10.

[0033] like Figure 1-5 As shown, the first connecting rod 14 and the second connecting rod 15 are rotatably connected, and the other end of the first connecting rod 14 is rotatably connected to the base 13, and the other end of the second connecting rod 15 is rotatably connected to the seat cushion frame 10, that is, the height distance between the base 13 and the seat cushion frame 10 can be adjusted by the first connecting rod 14 and the second connecting rod 15, so that the height adjustment of at least part of the seat cushion frame 10 can be achieved.

[0034] According to some embodiments of the present invention, a first sliding groove 16 is provided on the base 13 , and a first sliding block 17 adapted to the first sliding groove 16 is provided on the first connecting rod 14 , and the first sliding block 17 moves in the first sliding groove 16 .

[0035] like Figure 1-5 As shown, the first connecting rod 14 and the base 13 move relative to each other through the first sliding groove 16 and the first slider 17. The first sliding groove 16 and the first slider 17 mechanism convert the linear motion into a height change of the seat cushion frame 10. The structure is compact and easy to maintain.

[0036] In some optional embodiments, such as Figure 1-5 As shown, the arc-shaped design of the first slide groove 16 allows the seat cushion to remain stable during the lifting process, thereby improving the comfort of the user.

[0037] According to some embodiments of the present invention, the connecting rod assembly further includes a third connecting rod 18 , one end of the third connecting rod 18 is rotatably connected to the seat cushion frame 10 , and the other end of the third connecting rod 18 is connected to the base 13 .

[0038] like Figure 1-5 As shown, the seat cushion frame 10 and the seat are supported by a third connecting rod 18, which enhances the overall strength of the seat frame. One end of the third connecting rod 18 is rotatably connected to the seat cushion frame 10, allowing the seat frame to adjust its inclination angle, which is used to reduce the angle between the seat cushion frame 10 and the backrest frame 11 in a zero-gravity state.

[0039] According to some embodiments of the present invention, a second sliding groove 19 is provided on the base 13 , and a second slider 20 adapted to the second sliding groove 19 is provided on the third connecting rod 18 , and the second slider 20 moves in the second sliding groove 19 .

[0040] like Figure 1-5 As shown, the third connecting rod 18 and the base 13 move relative to each other through the second slide groove 19 and the second slider 20. The second slide groove 19 and the second slider 20 mechanism convert the linear motion into a height change of the seat cushion frame 10. The structure is compact and easy to maintain.

[0041] In some optional embodiments, such as Figure 1-5 As shown, the arc-shaped design of the second slide groove 19 enables the seat cushion to remain stable during the lifting process, thereby improving the comfort of the user.

[0042] In some optional embodiments, such as Figure 1-5As shown, the first link 14 and the third link 18 are arranged at intervals in the front-to-back direction of the seat. For example, along the front-to-back direction of the seat, the first link 14 is located in front of the third link 18, that is, in the event of a collision, the front part of the seat cushion frame 10 can be raised by the first link 14 and the second link 15, and the rear part of the seat cushion frame 10 can be lowered by the third link 18, thereby reducing the angle between the seat cushion frame 10 and the backrest frame 11 in the zero-gravity state, reducing the angle between the upper torso and the lower limbs, slowing down the tendency of the safety belt to slide toward the abdomen of the occupant, and reducing the injury to the abdomen of the occupant.

[0043] According to some embodiments of the present invention, at least a portion of the second slider 20 is deformable. When the second slider is deformed, the second slider slides from a first position to a second position, and the height of the first position is higher than the height of the second position.

[0044] Specifically, the second slider 20 is at least partially a deformable structure, and adaptive locking is achieved through structural characteristics. Figure 6 The second slider 20 is shown in the state where it is not deformed. Figure 7 As shown, this is the state of the second slider 20 after deformation. When the second slider is not deformed, its size and the second slide groove 19 cannot move relative to each other; when subjected to external impact, the second slider 20 is deformed, and the corresponding size of a certain direction of the deformed second slider 20 is reduced compared with before deformation. The second slider 20 slides from the first position of the second slide groove 19 to the second position of the second slide groove 19. The height of the first position is higher than the height of the second position, which is used to reduce the height between part of the seat cushion frame 10 and the base 13, and reduce the angle between the seat cushion frame 10 and the backrest frame 11 in the zero gravity state.

[0045] In some optional embodiments, such as Figure 2-5 As shown, along the front-to-back direction of the seat, the connection point between the third link 18 and the seat cushion frame 10 is behind the connection point between the second link 15 and the seat cushion frame 10, and the connection point between the third link 18 and the base 13 is behind the connection point between the first link 14 and the base 13. Figure 6-7As shown, along the height direction of the seat, the structure of the second slide groove 19 can be divided from top to bottom: a second slide groove upper section 101, a second slide groove middle section 102 and a second slide groove lower section 103. When the seat is in a zero gravity state, the second slider 20 is located in the second slide groove upper section 101, corresponding to the state where the second slider 20 is not deformed. When the force applied by the driving member 12 to the third connecting rod 18 is greater than the deformation threshold of the second slider 20, the second slider 20 is deformed, and the second slider 20 slides out from the second slide groove upper section 101, passes through the second slide groove middle section 102, and moves to the second slide groove lower section 103, so that the rear part of the seat cushion frame 10 tilts downward, reducing the angle between the seat cushion frame 10 and the backrest frame 11, thereby reducing the angle between the upper torso and the lower limbs, slowing down the tendency of the safety belt to slide toward the occupant's abdomen, and reducing the injury to the occupant's abdomen.

[0046] In some optional embodiments, such as Figure 6-7 As shown, along the height direction of the seat, the structure of the second slider 20 can be divided from top to bottom into: a second slider upper portion 104, a second slider middle portion 105 and a second slider lower portion 106, as shown in FIG. Figure 7 (a) shows the state where the second slider 20 is not deformed. When viewed from the side of the seat, the cross-section of the second slider 20 is circular, that is, the cross-section of the second slider upper portion 104, the second slider middle portion 105, and the second slider lower portion 106 is circular. Figure 7 As shown in (b), when the force applied by the driving member 12 to the third connecting rod 18 is greater than the deformation threshold of the second slider 20, the second slider 20 is deformed, and the middle portion 105 of the second slider can move relative to the upper portion 104 of the second slider and the lower portion 106 of the second slider, as shown in FIG. Figure 7 (c) shows the final state of the second slider 20 after deformation. Along the height of the seat, the second chute 19 can be divided, from top to bottom, into an upper second chute section 101, a middle second chute section 102, and a lower second chute section 103. Viewed from the side of the seat, the upper second chute section 101 is shaped like a major arc, with a diameter less than or equal to the diameter of the circular cross-section corresponding to the undeformed second slider 20. When the seat is in zero gravity, the second slider 20 is located in the upper second chute section 101 and cannot move relative to the second chute 19 when the seat is in zero gravity. Seen from the side of the seat, the extension direction of the middle section 102 of the second slide groove is inclined from top to bottom and forward, and the lower section 103 of the second slide groove extends in the front-to-back direction of the seat. When the driving member 12 drives the third link 18 to move forward, the driving force is greater than the deformation threshold of the second slider 20, and the middle section 105 of the second slider can move forward relative to the upper section 104 of the second slider and the lower section 106 of the second slider, thereby reducing the height dimension of the cross section of the second slider 20. Figure 7As shown in (d), the second slider 20 moves from the middle section 102 of the second chute to the lower section 103 of the second chute. In the event of a collision, the rear portion of the seat cushion frame 10 tilts downward, reducing the angle between the seat cushion frame 10 and the backrest frame 11. This reduces the angle between the upper torso and lower limbs, slowing the lap belt's tendency to slide toward the occupant's abdomen and minimizing abdominal injuries.

[0047] According to some embodiments of the present invention, the connecting rod assembly also includes: a fourth connecting rod 21 and a fifth connecting rod 22, one end of the fourth connecting rod 21 is rotatably connected to one end of the fifth connecting rod 22, the other end of the fourth connecting rod 21 is rotatably connected to the base 13, and the other end of the fifth connecting rod 22 is rotatably connected to the seat cushion frame 10; a sixth connecting rod 23, one end of the sixth connecting rod 23 is rotatably connected to the seat cushion frame 10, and the other end of the sixth connecting rod 23 is connected to the base 13.

[0048] like Figure 2-5 As shown, by adding a fourth connecting rod 21, a fifth connecting rod 22, and a sixth connecting rod 23, the adjustment efficiency and adjustment stability of the adjustment device are improved. Specifically, the fourth connecting rod 21 and the fifth connecting rod 22 are rotatably connected and connected between the seat cushion frame 10 and the base 13, thereby achieving the same function as the first connecting rod 14 and the second connecting rod 15. The sixth connecting rod 23 is connected between the seat cushion frame 10 and the base 13 to achieve the same function as the third connecting rod 18, improving the efficiency of reducing the angle between the seat cushion frame 10 and the backrest frame 11 and making the process of reducing the angle between the seat cushion frame 10 and the backrest frame 11 more stable.

[0049] In some optional embodiments, such as Figure 4-5 As shown, along the left and right direction of the seat, the first link 14 and the fourth link 21 are arranged at intervals, the second link 15 and the fifth link 22 are arranged at intervals, and the third link 18 and the sixth link 23 are arranged at intervals, so as to improve the adjustment efficiency and adjustment stability of the adjustment device.

[0050] In some optional embodiments, such as Figure 4-5As shown, a third slide groove 31 is provided on the base 13, and a third slider 32 adapted to the third slide groove 31 is provided on the fourth connecting rod 21, and the third slider 32 moves in the third slide groove 31; a fourth slide groove 33 is also provided on the base 13, and a fourth slider 34 adapted to the fourth slide groove 33 is provided on the sixth connecting rod 23, and the fourth slider 34 moves in the fourth slide groove 33. The fourth slider 34 is similar to the second slider 20 and can be deformed at least partially when subjected to force, and has two states. The fourth link 21 and the sixth link 23 are arranged at intervals in the front-to-back direction of the seat. Along the front-to-back direction of the seat, the fourth link 21 is located in front of the sixth link 23, that is, in the event of a collision, the front part of the seat cushion frame 10 can be raised by the movement of the fourth link 21 and the fifth link 22, as well as the movement of the first link 14 and the second link 15, and the rear part of the seat cushion frame 10 can be lowered by the joint action of the sixth link 23 and the third link 18, thereby reducing the angle between the seat cushion frame 10 and the backrest frame 11 in the zero-gravity state, reducing the angle between the upper torso and the lower limbs, slowing down the tendency of the safety belt to slide toward the abdomen of the occupant, and reducing the injury to the abdomen of the occupant.

[0051] According to some embodiments of the present invention, the adjustment device further includes: a first component 24 and a second component 25, the first connecting rod 14 and the fourth connecting rod 21 are fixedly connected via the first component 24, and / or the third connecting rod 18 and the sixth connecting rod 23 are fixedly connected via the second component 25, such as Figure 4-5 As shown, the structural stability of the adjusting device is improved.

[0052] In some optional embodiments, such as Figure 5 As shown, the first end 107 of the first component is fixedly connected to the first connecting rod docking hole 109 by a threaded manner, and the second end 108 of the first component is fixedly connected to the fourth connecting rod docking hole 110 by a threaded manner, and the first end 111 of the second component is fixedly connected to the third connecting rod docking hole 113 by a threaded manner, and the second end 112 of the second component is fixedly connected to the sixth connecting rod docking hole 114 by a threaded manner, so as to realize that the first connecting rod 14 and the fourth connecting rod 21 are fixedly connected through the first component 24, and the third connecting rod 18 and the sixth connecting rod 23 are fixedly connected through the second component 25.

[0053] According to some embodiments of the present invention, the adjusting device further includes: a third component 26 , the first component 24 and the second component 25 are fixedly connected via the third component 26 , and the driving member 12 is provided on the third component 26 for adjusting the length of the third component 26 .

[0054] like Figure 4-5As shown, in addition to improving the structural stability of the adjustment device by adding a third component 26, the driving member 12 is also arranged on the third component 26. By adjusting the length of the third component 26, on the one hand, it can drive the first component 24 to move, linking the first link 14 and the second link 15 to move, and at the same time linking the fourth link 21 and the fifth link 22 to move, so as to realize the raising of the front part of the seat cushion frame 10; on the other hand, it can drive the second component 25 to move, linking the third link 18 and the sixth link 23 to move, so as to realize the lowering of the rear part of the seat cushion frame 10, reduce the angle between the seat cushion frame 10 and the backrest frame 11, realize the reduction of the angle between the upper torso and lower limbs of the occupant, and reduce the injury to the occupant's abdomen.

[0055] In some optional embodiments, such as Figure 1-3 As shown, when the seat is in a normal state, the length of the third component 26 is the longest; when the seat is in a zero-gravity state, the length of the third component 26 is moderate; after the seat collides, the state adjusted by the adjustment device corresponds to a safe state, and the length of the third component 26 is the shortest, so as to reduce the angle between the seat cushion frame 10 and the backrest frame 11, thereby achieving the adjustment effect of multiple uses of the same component.

[0056] According to some embodiments of the present invention, the third component 26 includes: a first subcomponent 27 and a second subcomponent 28. The first subcomponent 27 is provided with a gear 29, and the second subcomponent 28 is provided with a rack 30. The driving member 12 is connected to the gear 29, and the gear 29 is engaged with the rack 30.

[0057] like Figure 4-5 As shown, the driving member 12 drives the gear 29 on the first sub-component 27 to rotate, and the gear 29 engages with the rack 30 on the second sub-component 28 to adjust the length of the third component 26. The length of the third component 26 is adjusted by the meshing movement of the gear 29 and the rack 30, thereby improving the reliability and response speed of the adjustment device.

[0058] In some optional embodiments, such as Figure 1 、 Figure 5 As shown, the seat is in a normal state, the gear 29 is meshed with the front end of the rack 30, that is, at this time, the length of the third component 26 is the longest, the first slider 17 is at the bottom end of the first slide 16, the third slider 32 is at the bottom end of the third slide 31, the second slider 20 is at the top end of the second slide 19, and the fourth slider 34 is at the top end of the fourth slide 33. The inclination angle of the seat cushion frame is the smallest, meeting the normal sitting posture requirements of the occupant. Figure 2 、 Figure 5As shown, the seat is in a zero-gravity state, the gear 29 is engaged in the middle of the rack 30, that is, at this time, the length of the third component 26 is moderate, the first slider 17 is in the middle of the first chute 16, the third slider 32 is in the middle of the third chute 31, the second slider 20 is at the top of the second chute 19, and the fourth slider 34 is at the top of the fourth chute 33. The front part of the seat frame is raised, and the backrest frame 11 rotates downward to meet the comfort needs of the passengers. In addition, the degree of elevation of the seat frame can be adjusted by engaging the gear 29 and the rack 30 at different positions to meet the needs of passengers with different body shapes. Figure 4 As shown, when the seat collides, the gear 29 moves to the right relative to the rack 30, driving the first slider 17 to move to the uppermost end of the first chute 16 through the first subassembly 27, and the third slider 32 to move to the uppermost end of the third chute 31. At this time, the second slider 20 and the fourth slider 34 do not deform, and the second slider 20 remains at the uppermost end of the second chute 19, and the fourth slider 34 remains at the uppermost end of the fourth chute 33, corresponding to the further elevation of the front portion of the seat cushion frame. Figure 3 、 Figure 5 As shown, the gear 29 moves further to the right relative to the rack 30, and the gear 29 engages at the rear end of the rack 30. The seat is in a safe state, that is, the state adjusted by the adjustment device after the seat collides, that is, at this time the length of the third component 26 is the shortest, the first slider 17 is at the upper end of the first slide 16, the third slider 32 is at the upper end of the third slide 31, the second slider 20 is at the lower end of the second slide 19, and the fourth slider 34 is at the lower end of the fourth slide 33. The front part of the seat cushion frame is further raised, and the rear part of the seat cushion frame is lowered, reducing the angle between the seat cushion frame 10 and the backrest frame 11, so as to reduce the angle between the occupant's upper torso and lower limbs, so as to achieve a self-locking state between the safety belt and the ilium of the occupant, thereby slowing down the tendency of the safety belt to slide toward the occupant's abdomen in a collision and reducing the injury to the occupant's abdomen.

[0059] The zero-gravity seat system according to the second aspect of the present invention includes any one of the above-mentioned zero-gravity seat frame mechanisms; a seat controller, which is connected to an adjustment device and is used to control the adjustment device to adjust the height of the seat cushion frame 10 to reduce the angle between the seat cushion frame 10 and the backrest frame 11 in the zero-gravity state.

[0060] According to the zero-gravity seat system of the embodiment of the present application, the seat controller controls the adjustment device to reduce the angle between the seat cushion frame 10 and the backrest frame 11 in the zero-gravity state, thereby reducing the angle between the occupant's upper torso and lower limbs, slowing down the tendency of the safety belt to slide toward the occupant's abdomen, and reducing injuries to the occupant's abdomen.

[0061] According to some embodiments of the present invention, the seat controller is configured to: in a zero gravity state, control the adjustment device to adjust the height of the seat cushion frame 10 according to the first feedback information to reduce the angle between the seat cushion frame 10 and the backrest frame 11; wherein: the first feedback information includes information about a vehicle collision.

[0062] Specifically, if Figure 2 As shown, when the seat is in a zero-gravity state, the ilium of the occupant's waist turns from an upright state to a tilted state, the angle between the safety belt and the ilium will increase, and the friction between the two will decrease accordingly. When a collision occurs, generally a head-on collision, the occupant moves forward and the rotation of the upper torso increases. Since the angle between the seat cushion frame 10 and the backrest frame 11 remains unchanged, the movement of the occupant in a collision increases the risk of the occupant diving. The safety belt will slide from the ilium of the occupant to the abdomen of the occupant, causing additional damage to the abdomen of the occupant. The zero-gravity seat system of the embodiment of the present application, as shown in FIG. Figure 2 As shown, when a collision occurs, the seat controller controls the adjustment device to reduce the angle between the seat cushion frame 10 and the backrest frame 11 in a zero-gravity state, thereby reducing the angle between the occupant's upper torso and lower limbs, causing the occupant's waist ilium to rotate from a tilted state to an upright state, thereby reducing the angle between the occupant's upper torso and lower limbs, thereby slowing down the tendency of the safety belt to slide toward the occupant's abdomen in a collision and reducing the injury to the occupant's abdomen.

[0063] According to some embodiments of the present invention, when controlling the adjustment device to adjust the height of the seat cushion frame 10, the seat controller is specifically configured to: control the first slider 17 in the adjustment device to move in a direction close to the seat cushion frame 10, and / or control the second slider 20 in the adjustment device to move in a direction away from the seat cushion frame 10.

[0064] like Figure 2-3 As shown, the seat controller controls the first slider 17 in the adjustment device to move in the direction close to the seat cushion frame 10 to achieve the increase of the front part of the seat cushion frame 10; the seat controller can also control the second slider 20 in the adjustment device to move away from the seat cushion frame 10 to achieve the decrease of the rear part of the seat cushion frame 10, reduce the angle between the seat cushion frame 10 and the backrest frame 11, and reduce the injury to the occupant's abdomen.

[0065] In some optional embodiments, such as Figure 2-3As shown, the seat controller controls the first slider 17 in the adjusting device to move in the direction close to the seat cushion frame 10, and controls the third slider 32 in the adjusting device to move in the direction close to the seat cushion frame 10, so as to realize the raising of the front part of the seat cushion frame 10; the seat controller can also control the second slider 20 in the adjusting device to move away from the seat cushion frame 10, and controls the fourth slider 34 in the adjusting device to move away from the seat cushion frame 10, so as to realize the lowering of the rear part of the seat cushion frame 10, reduce the angle between the seat cushion frame 10 and the backrest frame 11, and reduce the injury to the occupant's abdomen.

[0066] According to the third aspect of the present invention, a method for controlling a zero-gravity seat includes: in a zero-gravity state, when a vehicle collides, controlling the seat to switch to a safe state; wherein: the angle of the seat corresponding to the safe state is smaller than the angle corresponding to the seat in the zero-gravity state.

[0067] Specifically, according to the control method of the zero-gravity seat of the embodiment of the present application, when the seat is in a zero-gravity state, when a vehicle collides, the seat angle is controlled to be reduced, thereby reducing the angle between the occupant's upper torso and lower limbs, slowing down the tendency of the safety belt to slide toward the occupant's abdomen, and reducing the injury to the occupant's abdomen.

[0068] According to some embodiments of the present invention, the method for controlling a zero-gravity seat further includes: controlling the seat to switch between a normal state and a zero-gravity state according to first prompt information; the first prompt information includes user adjustment requirement information for the seat.

[0069] Specifically, the seat can be adjusted from a normal state to a zero-gravity state according to user needs, or from a zero-gravity state to a normal state according to user needs. Figure 1 As shown, when the seat is in a normal state, the angle between the seat cushion frame 10 and the backrest frame 11 is generally between 90° and 110°; Figure 2 As shown, when the seat is in a zero-gravity state, the angle between the seat cushion frame 10 and the backrest frame 11 is generally greater than 110°. When the seat is in a zero-gravity state, the seat surface can perfectly match the human body curve, thereby evenly distributing pressure, aiming to improve the comfort of the occupants and reduce the burden on muscles and spine.

[0070] In some optional embodiments, such as Figure 8As shown, the zero-gravity seat control method further includes: when the seat is not in a zero-gravity state, the seat is in a normal state by adjusting the length of the third component 26 in the adjustment device to the maximum. If a collision occurs in the normal state, the seat can be protected according to existing conventional protective measures. When the user requires the seat to be in a zero-gravity state, the seat is in a zero-gravity state by adjusting the length of the third component 26 in the adjustment device to an appropriate length. If a collision occurs while the seat is in the zero-gravity state, the front portion of the seat cushion frame 10 is raised after the length of the third component 26 is adjusted to the minimum, and the rear portion of the seat cushion frame 10 is lowered to achieve a safe state.

[0071] In some optional embodiments, such as Figure 9 As shown, the control method of the zero-gravity seat also includes: when a collision occurs when the seat is in a zero-gravity state, the length of the third component 26 is adjusted to the shortest, so that the second slider 20 is deformed, and the deformed second slider 20 moves along the second slide groove 19, from the upper section 101 of the second slide groove through the middle section 102 of the second slide groove to the lower section 103 of the second slide groove, so that the rear part of the seat cushion frame 10 is lowered, so that the seat is in a safe state, the angle between the seat cushion frame 10 and the backrest frame 11 is reduced, and the angle between the occupant's upper torso and lower limbs is reduced, so as to achieve a self-locking state between the safety belt and the occupant's ilium, slow down the tendency of the safety belt to slide toward the occupant's abdomen, and reduce the injury to the occupant's abdomen.

[0072] According to the fourth aspect of the present invention, the vehicle comprises any one of the zero-gravity seat frame mechanisms described above, or any one of the zero-gravity seat systems described above, or a control method for executing any one of the zero-gravity seats described above.
