In the deployed state 20, the second backrest 2 extends relative to the seat cushion 3, further stretching the length of the seat cushion 3 and the first backrest 1, and the length after deployment is convenient for passengers to rest, improving the comfort of the passengers. In some embodiments, in the deployed state 20, the seat cushion 3, the first backrest 1 and the second backrest 2 are sequentially laid horizontally. The seat cushion 3, the first backrest 1 and the second backrest 2 are arranged in sequence from front to back, and the upper surfaces of the three are flush and horizontally extended. By adding the second backrest 2 and laying the seat cushion 3, the first backrest 1 and the second backrest 2, the space for passengers to lie down and rest in the vehicle is increased, the problem that the length of the seat cushion 3 and the backrest is short after being laid flat in the related art and the passengers cannot lie down comfortably is solved, the deployment size is expanded, and the passengers can lie flat, improving the comfort.

[0048] In other embodiments, the seat cushion 3 and the first backrest 1 are laid horizontally, the second backrest 2 extends obliquely upward from the first backrest 1, and the second backrest 2 is arranged at a certain angle relative to the first backrest 1. The passengers can lean against the second backrest 2, and the seat cushion 3 and the first backrest 1 can support the entire leg, or the passengers can lie on the seat with the head slightly higher, improving the comfort. In some embodiments, the angle of the second backrest 2 relative to the first backrest 1 is adjustable, thereby effectively providing convenience for various angles required by the passengers when lying down. The passengers can position to the corresponding angle according to their own needs, improving the comfort of the passengers. In other embodiments, the deployed state includes a first deployed state and a second deployed state.

[0049] Figure 3 As shown Figure 1 Another angle structure diagram of the vehicle folding seat in the seating state is shown. In Figure 3In the embodiment shown, in order to facilitate the push-pull structure of the vehicle folding seat 18 to achieve the unfolding and folding recovery, the vehicle folding seat 18 comprises a sliding assembly 7, which is slidably connected to the seat cushion 3 and the vehicle body, so that the seat cushion 3 can slide forward and backward relative to the vehicle body. By setting the sliding assembly 7 to make the seat cushion 3 slide forward and backward, it moves forward during the process from the sitting state 19 to the unfolded state 20, leaving more space for the first backrest 1 and the second backrest 2 to unfold, so as to utilize the space in front of the seat, so that the unfolded seat can be set longer, improving the comfort of the passengers. It moves backward during the process from the unfolded state 20 to the sitting state 19.

[0050] Figure 4 As shown Figure 1 Another angle structure of the vehicle folding seat is shown. In Figure 4 In the embodiment shown, in order to make the seat cushion 3 move along the sliding assembly 7 while the first backrest 1 and the second backrest 2 also move, and finally achieve the flat state, the vehicle folding seat 18 comprises a seat-back connecting hinge 5 and a backrest connecting hinge 4, the seat-back connecting hinge 5 connects the seat cushion 3 and the first backrest 1, the backrest connecting hinge 4 connects the first backrest 1 and the second backrest 2, when the seat cushion 3 slides forward in the sitting state 19 through the sliding assembly 7, the first backrest 1 moves through the seat-back connecting hinge 5, and the second backrest 2 moves to the unfolded state 20 through the backrest connecting hinge 4. The first backrest 1 and the seat cushion 3 are connected together through the seat-back connecting hinge 5, and when the seat cushion 3 moves along the sliding assembly 7, the first backrest 1 is correspondingly extended and lengthened, widening the space for human use of the seat. The second backrest 2 is directly connected to the first backrest 1 through the backrest connecting hinge 4, and indirectly connected to the seat cushion 3, and when the seat cushion 3 moves along the sliding assembly 7, the second backrest 2 is extended and lengthened with the first backrest 1 until the sliding assembly 7 pulls the seat cushion 3, the first backrest 1 and the second backrest 2 to unfold to the flat state. In this process, the seating surface of the seat is always upward, ensuring the comfort of the passengers. Moreover, the seat-back connecting hinge 5 and the backrest connecting hinge 4 are accommodated between the seat cushion 3 and the first backrest 1 and between the first backrest 1 and the second backrest 2 in the unfolded state 20, so that the seat cushion 3, the first backrest 1 and the second backrest 2 seamlessly connect in the unfolded state 20, improving the user experience. The seat cushion 3 slides, and the first backrest 1 and the second backrest 2 move accordingly. By controlling the sliding of the seat cushion 3, the movement of the first backrest 1 and the second backrest 2 can be controlled, and the conversion between the unfolded state 20 and the sitting state 19 is simple, convenient and easy to operate. Optionally, the seat-back connecting hinge 5 comprises an upper hinge connecting plate, a lower hinge connecting plate, a limiting pin and a limiting slot, the limiting pin is welded on the upper hinge connecting plate and fixed to the first backrest through a bolt, and the lower hinge connecting plate is provided with the limiting slot and fixed to the seat cushion through a bolt. In the sitting state, the limiting pin is located at the upper limit position of the limiting slot, at which time the first backrest is relatively fixed and cannot be turned forward.

[0051] Figure 5 Fig. 1 shows a partial view of a vehicle folding seat in a sitting state. Fig. 2 shows a partial view of a vehicle folding seat in an unfolded state. Figure 5 In the embodiment shown, the sliding assembly 7 comprises a horizontal telescopic assembly 8, one end of which is connected to the seat cushion 3, the other end of which is connected to the vehicle body, and which extends along the front-rear direction of the seat cushion 3 and can telescopically move forward and backward to drive the seat cushion 3 to slide forward and backward. The horizontal telescopic assembly 8 moves while driving the seat cushion 3 to move, and the angle between the seat cushion 3 and the first backrest 1 and the second backrest 2 is opened accordingly, and the total length is continuously increased, and finally a larger seat space is formed by laying flat. In addition, by arranging the horizontal telescopic assembly 8, one-key unfolding and folding of the seat cushion 3, the first backrest 1 and the second backrest 2 can be achieved. The horizontal telescopic assembly 8 moves while driving the seat cushion 3, the first backrest 1 and the second backrest 2 to move, reducing the cumbersome adjustment of the backrest angle in the related art. In some embodiments, the horizontal telescopic assembly 8 comprises an electrically extendable support rod extending horizontally. Optionally, the electrically extendable support rod can be arranged on both sides of the seat cushion 3 to achieve bilateral arrangement and maintain stability. When the seat cushion 3 slides forward to the limit position formed by the sliding assembly 7, the electrically extendable support rod stops and is locked, and at this time the first backrest 1 and the second backrest 2 are also folded in place and kept horizontal under the limit of the seatback connecting hinge 5 and the backrest connecting hinge 4.

[0052] In some embodiments, the sliding assembly 7 further comprises a first slide rail 701, a second slide rail 702 and a third slide rail 703. The first slide rail 701 is fixedly arranged on the vehicle body, the second slide rail 702 is fixedly arranged on the seat cushion 3, and the third slide rail 703 connects the first slide rail 701 and the second slide rail 702, and the third slide rail 703 slides forward and backward relative to the first slide rail 701, and the second slide rail 702 slides forward and backward relative to the third slide rail 703. When the vehicle folding seat switches from the sitting state 19 to the unfolded state 20, the second slide rail 702 moves towards the front end of the vehicle relative to the third slide rail 703, and at the same time, the third slide rail 703 also moves towards the front end of the vehicle relative to the first slide rail 701, and the seat cushion 3 as a whole moves towards the front end of the vehicle, providing sufficient space for the unfolding of the first backrest 1 and the second backrest 2.

[0053] In some embodiments, the vehicle folding seat 18 comprises a controller 17 electrically connected to the horizontal telescopic assembly 8. In the unfolded state 20, the controller 17 is used to control the horizontal telescopic assembly 8 to stretch, and in the sitting state 19, the controller 17 is used to control the horizontal telescopic assembly 8 to contract. The occupant controls the controller 17 to switch the vehicle folding seat 18 between the unfolded state 20 and the sitting state 19, and controls the seat cushion 3, the first backrest 1 and the second backrest 2 to contract and stretch at the same time through the controller 17, achieving one-key conversion and avoiding the cumbersome sequential control in the related art.

[0054] Figure 6 Figure 6 shows another angle of the structure of the folding seat in the unfolded state. Figure 6 In the embodiment shown, the folding seat 18 comprises at least two support legs 11 arranged below the seat cushion 3 to support the seat cushion 3, the bottom end of the support legs 11 being provided with a pulley 15, the support legs 11 moving forward and backward with the seat cushion 3 when the seat cushion 3 slides forward and backward. The support legs 11 are used to support the seat cushion 3 to keep the seat cushion 3 in a balanced state, the pulley 15 at the bottom of the support legs 11 making a rolling movement towards the front end of the car during the movement of the seat cushion 3 along the sliding assembly 7 towards the front end of the car, reducing the resistance generated during the unfolding of the folding seat 18 and reducing the damage to the car itself.

[0055] Figure 7 Figure 7 shows a partial view of the rotating hinge of the folding seat. In combination with Figure 1 , Figure 7 In the embodiment shown, in order to more stably install the second backrest 2 in the car, the folding seat 18 comprises a rotating hinge 6, the second backrest 2 comprising a first end 201 and a second end 202 opposite to each other, the first end 201 being rotatably connected to the first backrest 1, the second end 202 being connected to the car body through the rotating hinge 6, the second backrest 2 rotating relative to the car body during the conversion between the unfolded state 20 and the seating state 19. During the conversion between the unfolded state 20 and the seating state 19 of the folding seat 18, the second backrest 2 connected to the first backrest 1 slides accordingly with the forward movement of the seat cushion 3, the rotating hinge 6 connecting the second backrest 2 to the car body so that the second backrest 2 does not randomly sway and cause impact during the unfolding process, effectively maintaining the stability of the second backrest 2 during the conversion between the two states. The rotating hinge 6 connects the second backrest 2 and the car body at the second end 202 of the second backrest 2, the first backrest 1 moving forward and rotating downward when the seat cushion 3 slides forward, one end of the second backrest 2 being rotatably connected to the first backrest 1 and the other end being rotatably connected to the car body, so that the second backrest 2 can be pulled out and unfolded relative to the first backrest 1, so that the folding seat 18 can be unfolded more easily and smoothly.

[0056] In the embodiment shown, Figure 1 and Figure 4In the embodiment shown, the vehicle folding seat 18 comprises a vertical telescopic assembly 10 connected to a controller 17, the bottom end of the vertical telescopic assembly 10 is connected to the vehicle body, the controller 17 controls the vertical telescopic assembly 10 to perform vertical telescopic movement, when the controller 17 controls the vertical telescopic assembly 10 to be in the collapsed state, the top end of the vertical telescopic assembly 10 is lower than the cushion 3. When the controller 17 controls the vertical telescopic assembly 10 to be in the expanded state 20, the vertical telescopic assembly 10 abuts against the first backrest 1 and lifts the first backrest 1 upward, so that the first backrest 1 and the second backrest 2 form an angle and gradually fit to a set height, after reaching the set height, the controller 17 controls the horizontal telescopic assembly 8 to gradually collapse to the seating state 19, and the controller 17 controls the vertical telescopic assembly 10 to collapse downward below the cushion 3 and leave a certain gap with the cushion 3 after the horizontal telescopic assembly 8 is completely collapsed, at this time, the cushion 3 moves backward without obstacles, and the first backrest 1 and the second backrest 2 collapse to the set height and finally change to the seating state 19. In the expanded state 20, the vertical telescopic assembly 10 is located below the first backrest 1, when the vertical telescopic assembly 10 extends, it abuts against the first backrest 1 upward, so that the first backrest 1 rotates upward to the position in the seating state 19, and when the first backrest 1 is in the position in the seating state 19, the vertical telescopic assembly 10 collapses and the cushion 3 slides backward above the vertical telescopic assembly 10. In the expanded state 20, the vertical telescopic assembly 10 extends upward, lifts the first backrest 1, and the first backrest 1 rotates upward and forward, and extends upward and forward relative to the cushion 3, until the vertical telescopic assembly 10 extends to the maximum length, and the angle between the first backrest 1 and the cushion 3 reaches the set angle. Then the vertical telescopic assembly 10 retracts downward, and does not hinder the cushion 3 to move backward, so that the vehicle folding seat 18 switches to the seating state 19, and it is easier to switch to the seating state 19. The vertical telescopic assembly is collapsed and stored below the cushion 3 without being used, and keeps a certain distance from the cushion 3, which effectively ensures the safety of the passengers, and facilitates the rotation and fitting of the first backrest 1 and the second backrest 2 in the use state, so as to promote the vehicle folding seat 18 to enter the seating state 19. In some embodiments, the vertical telescopic assembly 10 comprises a vertically extending electric support rod.

In the embodiment shown, the vehicle folding seat 18 comprises a locking assembly 13, the locking assembly 13 is connected to the controller 17, and the controller 17 controls the locking assembly 13 to be in the locking state 21 or the unlocking state 22. When the controller 17 controls the locking assembly 13 to be in the locking state 21, the locking assembly 13 is in the locking state, and the first backrest 1 and the second backrest 2 are locked in the expanded state 20. When the controller 17 controls the locking assembly 13 to be in the unlocking state 22, the locking assembly 13 is in the unlocking state, and the first backrest 1 and the second backrest 2 are unlocked and can be switched to the seating state 19. Figure 3 and Figure 8 In the embodiment shown, the vehicle folding seat 18 comprises a headrest 12, and in the seating state 19, the headrest 12 is located above the first backrest 1. The headrest 12 is arranged to facilitate the passengers to rest their heads on the headrest 12 when they are sitting, which is ergonomic and improves the riding experience of the passengers.

[0058] In order to facilitate the folding of the vehicle folding seat 18 in the unfolded state 20, the headrest 12 can be accommodated, avoiding certain discomfort to the passengers, and the second backrest 2 is provided with a recess 16 at one end connected to the first backrest 1. In the unfolded state 20, the connecting part of the headrest 12 and the first backrest 1 can be accommodated in the recess 16, and the headrest 12 is located on the side of the second backrest 2 away from the first backrest 1. Specifically, in some embodiments, the headrest 12 is fixedly connected to the vehicle body, and in the unfolded state 20, the headrest 12 is located at the rear end of the second backrest 2, which does not affect the passengers lying flat in the vehicle, and when the passengers need to sit up, they can lean on the headrest 12. In other embodiments, the headrest 12 is detachably connected to the vehicle body, and when the passengers do not need to use the headrest 12, they can detach the headrest 12 from the vehicle body. The connecting part between the headrest 12 and the first backrest 1 is accommodated in the recess 16, which is beneficial to the first backrest 1 and the second backrest 2 to keep flat in the unfolded state 20, avoiding the protruding setting of the connecting part between the headrest 12 and the first backrest 1 to the passengers, causing poor user experience.

[0059] In some embodiments, the headrest 12 is connected to the vehicle body and separated from the first backrest 1. The headrest 12 is connected to the vehicle body, so that the headrest 12 is arranged independently of the seat cushion 3 and the first backrest 1, reducing the need to remove the headrest 12 when replacing or cleaning the seat cushion 3 and the backrest, improving convenience.
