[0029] The utility model is further described below in conjunction with embodiments and drawings.

[0030] A car comprises a vehicle body and a seat that can be transformed into a bed. The structure of the seat will be described in detail below.

[0031] like Figure 1 and Figure 3 As shown, a seat that can be transformed into a bed includes a seat frame 2, a backrest assembly, and a slide rail assembly 1 located at the bottom of the seat frame 2, wherein the slide rail assembly 1 is used to enable the seat frame 2 to be assembled into the interior of the vehicle body so as to be movable forward and backward. Figure 6As shown, in the present embodiment, the slide rail assembly 1 includes an upper slide rail 12 and a lower slide rail 11. The lower slide rail 11 is fixedly mounted inside the vehicle body and extends along the length direction of the vehicle body. The upper slide rail 12 is slidably arranged on the lower slide rail 11, and the lower end of the seat frame 2 is fixedly assembled on the upper slide rail 12. A mounting support 5 is also fixedly provided inside the vehicle body, and the mounting support 5 is located behind the slide rail assembly 1. Furthermore, the backrest assembly is a double backrest structure, which includes a front backrest 3 and a rear backrest 4. The upper end of the front backrest 3 is rotatably connected to the upper end of the rear backrest 4, the lower end of the front backrest 3 is rotatably mounted on the rear end of the seat frame 2, and the lower end of the rear backrest 4 is rotatably connected to the mounting support 5. The seat has a sitting mode and a lying mode. In the sitting mode, the seat frame 2 is located at the rear end of the slide rail assembly 1. At this time, the front backrest 3 and the rear backrest 4 are arranged overlappingly (refer to Figure 4 ), the upper slide rail 12 drives the seat frame 2 to slide forward, which can pull the front backrest 3 to tilt backward and the rear backrest 4 to tilt forward, so that the seat changes from the sitting mode to the lying mode (reference Figure 7 ). Driving the upper slide rail 12 to slide forward and backward along the lower slide rail 11 is a prior art and will not be described in detail here.

[0032] When the seat needs to be transformed into a bed, the upper slide rail 12 drives the seat frame 2 to slide forward. Since the lower end of the front backrest 3 is rotatably connected to the rear end of the seat frame 2, the upper end of the front backrest 3 is rotatably connected to the upper end of the rear backrest 4, and the lower end of the rear backrest 4 is rotatably connected to the mounting support 5, the seat frame 2 can pull the front backrest 3 to slide and rotate backward along with the seat frame 2 during the forward movement, and at the same time, drive the rear backrest 4 to rotate forward around the mounting support 5 until the front backrest 3 and the rear backrest 4 are completely laid flat (refer to Figure 6 and 7 ), thereby realizing the transformation of the seat into a bed, which has the technical advantages of intuitive and convenient operation and appropriate overall structure size, and can meet the support length and comfort of users lying flat.

[0033] Furthermore, Figure 1 and 3 As shown, the upper part of the backrest assembly is provided with an adapter component 7, and the two ends of the adapter component 7 are respectively rotatably connected to the upper ends of the front backrest 3 and the rear backrest 4. The backrest assembly is equipped with an angle adjustment driver 6, which can drive the front backrest 3 or the rear backrest 4 to rotate forward and backward. With such a design, in the sitting mode, the front backrest 3, the adapter component 7, the rear backrest 4 and the "integral formed by the seat frame 2 and the mounting support 5" form a four-bar structure, which drives the front backrest 3 or the rear backrest 4 to rotate, and can make the front backrest 3 and the rear backrest 4 rotate synchronously, so as to achieve the purpose of adjusting the backrest inclination angle in a small range and meet the user's comfort needs in the sitting state.

[0034] Depend on Figure 3It can be seen that in this embodiment, the angle adjustment driver 6 is arranged on the rear backrest 4. When the seat is in the sitting position, the angle adjustment driver 6 drives the rear backrest 4 to rotate forward and backward, which can drive the front backrest 3 to rotate synchronously. In addition, when the seat is in the lying mode, the angle adjustment driver 6 drives the rear backrest 4 to rotate upward, which can drive the front backrest 3 to rotate upward and pull the seat frame 2 to slide backward, thereby completing the transformation of the seat from the lying mode to the sitting mode, further improving the convenience of operation.

[0035] Please refer to Figure 1 and 2 The front backrest 3 has a first cross bar 31 at the upper end, and the rear backrest 4 has a second cross bar 41 at the upper end. Figure 5 As shown, the adapter component 7 is a block structure, and both ends of the length direction thereof are provided with connecting through holes 71, and the first cross bar 31 and the second cross bar 41 are respectively rotatably supported in the two connecting through holes 71. In this embodiment, the adapter component 7 is a split structure, which is formed by buckling the upper and lower parts for easy assembly.

[0036] Re-attend Figure 3 A torsion spring a is provided between the adapter component 7 and the rear backrest 4, and the torsion spring a applies a force that deforms the angle between the adapter component 7 and the rear backrest 4. The advantage of such a design is that when the seat is in the sitting mode, the gap between the adapter component 7 and the rear backrest 4 can be eliminated, ensuring that the front backrest 3 and the rear backrest 4 are always tightly connected, thereby ensuring the stability of the overall structure. When the seat is retracted from the lying mode to the sitting mode, the torsion spring a can ensure that the connection position between the front backrest 3 and the rear backrest 4 has an upward rotation pre-thrust force, thereby ensuring the stability and reliability of the merging of the front backrest 3 and the rear backrest 4. In this embodiment, the torsion spring a is located between the adapter component 7 and the end of the second crossbar 41.

[0037] like Figure 3 As shown, in order to improve the reliability of the rotation connection between the front backrest 3 and the rear backrest 4, in this embodiment, there are two sets of adapter components 7. The two sets of adapter components 7 are distributed along the width direction of the backrest assembly. At the same time, there are also two sets of torsion springs a, which are arranged at both ends of the second crossbar 41.

[0038] Please refer to Figure 3 In this embodiment, there are two groups of mounting supports 5 , which are respectively located at both sides of the lower end of the rear backrest 4 , and both sides of the lower end of the rear backrest 4 are rotatably connected to the two groups of mounting supports 5 .

[0039] like Figure 1 As shown, both sides of the rear end of the seat frame 2 are fixedly provided with adapters 21 extending upward, and the lower end of the front backrest 3 is rotatably mounted on the two adapters 21.

[0040] Finally, it should be noted that the above description is only the preferred embodiment of the present utility model.
