Description

Technical Field

[0001] This utility model relates to a seat, and more particularly to a three-person zero-gravity seat for automobiles. Background Technology

[0002] Commercial vehicles are a common mode of transportation for daily commutes and business trips.

[0040] like Figures 1 to 13 The image shows a three-person zero-gravity car seat, comprising a six-part seat A and a four-part seat B.

[0041] The six-segment seat A includes a backrest connecting plate 1, a seat connecting plate 2, a middle connecting plate 3, a seat assembly 4, a backrest assembly 5, a seat connecting rod 12, and a leg support assembly 10; the bottom end of the backrest assembly 5 is disposed on a first lead screw 602, and a first angle adjustment assembly 6 is provided on the first lead screw 602; one end of the seat assembly 4 near the backrest assembly is disposed on a second lead screw 702, and a second angle adjustment assembly 7 is provided on the second lead screw 702;

[0042] The backrest connecting plate 1 is connected to the backrest assembly 5 at one end and to the first angle adjustment assembly 6 at the other end; the middle connecting plate 3 is disposed on one side of the first angle adjustment assembly 6 at one end and connected to the second angle adjustment assembly 7 at the other end; the seat connecting plate 2 is disposed on one side of the second angle adjustment assembly 7 at one end and connected to the seat assembly 4 at the other end.

[0043] The seat assembly 4 is disposed on the third lead screw 902 at the end away from the backrest assembly 5, and the third lead screw 902 is provided with a zero gravity drive assembly 9;

[0044] The leg support assembly 10 is mounted on the fourth lead screw 1102 via the leg support connecting rod 1104, and the fourth lead screw 1102 is provided with a leg support angle adjustment assembly 11; the seat assembly 4 is connected to the fourth lead screw 1102 via the seat connecting rod 12, and the seat assembly 4, the backrest assembly 5 and the leg support assembly 10 are all provided with sponge pads 8.

[0045] The intermediate connecting plate 3, under the action of the second angle adjustment component 7, drives the backrest assembly 5 to rotate away from the seat assembly and to a horizontal state with the seat assembly 4; the backrest connecting plate 1, under the action of the first angle adjustment component 6, drives the backrest assembly 5 to rotate towards the seat assembly 4 and to a folded state on the seat assembly 4; the leg support assembly 10, under the action of the fourth lead screw 1102, rotates to a state flush with the seat assembly 4; the end of the seat assembly 4 away from the backrest assembly 5 is lifted upward under the drive of the zero gravity drive component 9.

[0046] The quarter-seat and the six-seat have the same structure. The various states of the quarter-seat and the six-seat in this application can be driven independently.

[0047] The backrest assembly, seat assembly, and leg rest assembly 10 in this application are in the following three states:

[0048] 1. Zero Gravity State: Activate the second angle adjustment component 7, which drives the middle connecting plate 3, the first angle adjustment component 6, the backrest connecting plate 1, and the backrest assembly 5 to rotate away from the seat assembly 4, so that the backrest assembly 5 and the seat assembly 4 form an obtuse angle; then activate the zero gravity drive component 9, which drives the end of the seat assembly 4 away from the backrest assembly 5 to lift upward, realizing the zero gravity state of the seat and improving passenger comfort;

[0049] II. Horizontal State: After the seat assembly 4 and backrest assembly 5 are in a naturally vertical state, activate the second angle adjustment component 7. This component drives the intermediate connecting plate 3, the first angle adjustment component 6, the backrest connecting plate 1, and the backrest assembly 5 to rotate away from the seat assembly 4 until the backrest assembly 5 and seat assembly 4 are horizontal. At this point, the seating area is extended. Activate the leg rest angle adjustment component 11, which drives the leg rest assembly 10 to rotate until the leg rest assembly 10 is aligned with the seat assembly. The four components are in a horizontal position, ultimately forming a bed-like planar support structure between the backrest assembly 5, seat assembly 4, and leg support assembly 10. This allows passengers to lie down on the seat, improving comfort and increasing the seat's functionality. When passengers do not need to lie down, the second angle adjustment assembly 7 can be activated, causing the middle connecting plate 3, the first angle adjustment assembly 6, and the backrest connecting plate 1 to rotate the backrest assembly 5 towards the seat assembly 4. The leg support angle adjustment assembly 11 can then be activated, causing the leg support assembly 10 to return to its original position, ultimately resulting in the backrest assembly 5, seat assembly 4, and leg support assembly 10 being in a natural state.

[0050] 3. Folding state: After the seat assembly 4 and backrest assembly 5 are in a natural vertical position, the first angle adjustment assembly 6 is activated. The first angle adjustment assembly 6 drives the backrest connecting plate 1 and the backrest assembly 5 to move closer to the seat assembly 4 until the backrest assembly 5 is folded onto the seat assembly 4. At this time, the backrest assembly 5 is folded onto the seat assembly 4, which reduces the space occupied by the backrest assembly 5 in the business vehicle when it is in a vertical or horizontal state. It is convenient to place luggage or items on the backrest assembly 4, which increases the volume of the vehicle and improves the versatility of the folding seat.

[0051] Since the four-quarter and six-quarter seats in this application have the same structure, their various states can be adjusted independently, improving the adaptability of the seats to meet the needs of different passengers.

[0052] In a preferred embodiment, the first angle adjustment assembly 6 includes a first angle adjustment motor 601 and a first angle disk 603. The first lead screw 602 is disposed at the axis of the first angle adjustment motor 601. The first lead screw 602 is provided with a backrest connecting plate 1 and the first angle disk 603. One end of the intermediate connecting plate 3 is fixedly disposed on one side of the first angle disk 603 through a base. The first angle adjustment motor 601 drives the backrest connecting plate 1 to rotate the backrest assembly 5 toward the seat assembly 4.

[0053] The second angle adjustment assembly 7 includes a second angle adjustment motor 701 and a second angle disk 703. The second lead screw 702 is mounted on the shaft of the second angle adjustment motor 701. The other end of the intermediate connecting plate 3 and the second angle disk 703 are mounted on the second lead screw 702. One end of the seat connecting plate 2 is fixedly mounted on the second angle disk 703 via a base. The second angle adjustment motor 701 drives the intermediate connecting plate 3 to rotate the first angle adjustment assembly 6 and the backrest assembly 5 away from the seat assembly 4.

[0054] The zero-gravity drive assembly 9 includes a zero-gravity motor 901 and a zero-gravity disk 903. The third lead screw 902 is located at the axis of the zero-gravity motor 901. The zero-gravity disk 903 is connected to a zero-gravity connecting rod 904. The other end of the zero-gravity connecting rod 904 is connected to one end of the seat assembly 4 near the leg support assembly.

[0055] The leg support angle adjustment assembly 11 includes a leg support motor 1101 and a leg support disc 1103. The fourth lead screw 1102 is located at the axis of the leg support motor 1101. The fourth lead screw 1102 is provided with a leg support connecting rod 1104 connected to the leg support disc 1103. The leg support connecting rod 1104 is connected to the leg support assembly 10.

[0056] When a passenger needs to adjust the backrest assembly 5 from a naturally vertical position to a horizontal position with the seat assembly 4, the second angle adjustment motor 701 is first activated. The rotation of the second angle adjustment motor 701 drives the second lead screw 702 to rotate. The second lead screw 702 then drives the intermediate connecting plate 3 and the second angle disc 703 mounted on it to rotate. This, in turn, causes the intermediate connecting plate 3, the first angle adjustment assembly 6, and the backrest connecting plate 1 to rotate the backrest assembly 5 until the backrest assembly 5 rotates. The backrest assembly 5 is adjusted so that it is level with the seat assembly 4. When the leg support motor 1101 is activated, the leg support motor 1101 drives the fourth lead screw 1102 to rotate, which in turn drives the leg support disc 1103 to rotate. The leg support disc 1103 drives the leg support connecting rod 1104 to rotate, until the leg support assembly 10 is level with the seat assembly 4. This creates a planar support structure similar to a bed between the backrest assembly 5, the seat assembly 4, and the leg support assembly 10, making it easier for passengers to lie down and rest, thus improving comfort.

[0057] When it is necessary to adjust the backrest assembly 5 and seat assembly 4 from their natural vertical state to the point where the backrest assembly 5 is folded onto the seat assembly 4, the first angle adjustment motor 601 is first started. The first angle adjustment motor 601 drives the first lead screw 602 to rotate, the first lead screw 602 drives the first angle disc 603 to rotate, the first angle disc drives the backrest connecting plate 1, and then drives the backrest assembly 5 to rotate towards the seat assembly 4 until the backrest assembly 5 is completely folded onto the seat assembly 1, reducing space occupation, improving in-vehicle storage capacity, and enhancing the multi-functionality of the seat.

[0058] When it is necessary to adjust the backrest assembly 5 and seat assembly 4 from a natural vertical state to a zero-gravity state, the zero-gravity motor 901 is activated. The zero-gravity motor 901 drives the third lead screw 902 to rotate, which in turn drives the third disc 903 to rotate. This, in turn, drives the zero-gravity connecting rod 904 through the third disc to lift the seat assembly near the leg rest assembly upwards. The second angle adjustment motor 701 is then activated, which drives the first lead screw 702 to rotate, causing the second angle disc to rotate. This, in turn, causes the intermediate connecting plate 3, the first angle adjustment assembly 6, the backrest connecting plate 1, and the backrest assembly 5 to rotate away from the seat assembly 4, so that the backrest assembly 5 and the seat assembly 4 form an obtuse angle, achieving a zero-gravity state for the seat and improving passenger comfort.

[0059] In a preferred embodiment, the backrest connecting plate 1 and the intermediate connecting plate 3 are respectively located on both sides of the first angle disc 603. A first limiting post 101 is provided on one end of the backrest connecting plate 1, which is mounted on the first lead screw 602. A first limiting groove 301 is provided on one end of the intermediate connecting plate 3, which is mounted on the first lead screw 602. The first limiting groove 301 is located near the seat assembly 4, and the first limiting post 101 slides along the first limiting groove 301. Since one end of the intermediate connecting plate 3 is fixed to one side of the first angle disc 603 via a base, when the first lead screw 602 drives the backrest connecting plate 1, thereby driving the backrest assembly 5 to rotate towards the seat assembly 4, one end of the intermediate connecting plate 3 initially… The backrest connecting plate 1 remains stationary. During the rotation of the backrest connecting plate 1 by the first lead screw 602 driven by the first angle adjustment motor 601, the first limiting post 101 on the backrest connecting plate 1 slides along the corresponding first limiting groove 301, improving the stability of the backrest connecting plate 1 rotating towards the seat assembly 4. Furthermore, the first limiting groove 301 in this application is a 1 / 4 arc-shaped groove, and the sliding angle of the first limiting post 101 along the first limiting groove 301 is 90°. That is, the angle between the starting and ending positions of the first limiting post 101 sliding along the first limiting groove 301 and the center of the circle is 90°, thus enabling the backrest connecting plate 1 to rotate the backrest assembly 5 by 90°, ultimately achieving the complete folding of the backrest assembly 5 onto the seat assembly 4.

[0060] The intermediate connecting plate 3 and the seat connecting plate 2 are respectively located on both sides of the second angle disc 703. The intermediate connecting plate 3, mounted on the second lead screw 702, has a second limiting post 302 at one end, and the seat connecting plate 2, mounted on the second lead screw 702, has a second limiting groove 201 at one end. The second limiting groove 201 is located on the side away from the seat assembly 4, and the second limiting post 302 slides along the second limiting groove 201. Since the seat connecting plate 2 is fixedly mounted on one side of the second angle disc 703 via the base, it remains stationary while the intermediate connecting plate 3, the first angle adjustment assembly 6, and the backrest connecting plate 1 drive the backrest assembly 5 to rotate. When the second angle adjustment motor 701 drives the second lead screw 702 to rotate... During the rotation of the intermediate connecting plate 3, the second limiting post 302 set on the intermediate connecting plate 3 slides along the second limiting groove 201 on the corresponding seat connecting plate, ensuring the stability of the intermediate connecting plate 3 in driving the backrest assembly to rotate away from the seat assembly; at the same time, the second limiting groove 201 is a 1 / 4 arc groove, and the angle at which the second limiting post 302 slides along the second limiting groove 201 is 90°, that is, the angle between the starting position and the ending position of the second limiting post 302 sliding along the second limiting groove 201 and the center is 90°, realizing that the intermediate connecting plate 3 drives the backrest assembly 5 to rotate away from the seat assembly by 90°, and finally realizes that the backrest assembly 5 and the seat assembly 4 are horizontal, realizing the overall length of the seat is extended, making it convenient for passengers to lie down and rest.

[0061] In a preferred embodiment, there are two first angle discs 603, each connected to a backrest connecting plate 1, improving the stability of the first angle disc 603 driving the backrest connecting plate 1 to rotate; there are two second angle discs 703, each connected to a middle connecting plate 3, improving the stability of the second angle disc 703 driving the middle connecting plate 3 to rotate, thereby driving the backrest assembly 1 to rotate; there are two zero-gravity discs 903, each connected to a zero-gravity connecting rod 904, so that the zero-gravity disc 903 drives the zero-gravity connecting rod 904 to rotate, thereby driving one end of the seat assembly 4 connected to the leg support assembly 10 to lift upwards, ensuring the stability of the seat assembly 4 lifting upwards; there are two leg support discs 1103, each connected to a leg support connecting rod 1104, improving the stability of the leg support rotating driven by the leg support connecting rod 1104.
