For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0017] like Figures 1 to 2 As shown, this embodiment provides a three-row zero-gravity seat with sliding rails that can achieve forward seat lifting, including a seat cushion assembly, a seat cushion forward lifting component 4, and a backrest assembly; wherein, the seat cushion assembly includes a seat cushion bottom frame, a seat cushion side panel frame 2, a seat cushion rear cross tube 3, a seat cushion front cross tube, and a rear support arm. The front end of the seat cushion bottom frame is connected to the seat cushion side panel frame 2 through the seat cushion forward lifting component 4, and the rear end is connected to the seat cushion side panel frame 2 through the rear support arm; the seat cushion rear cross tube 3 and the seat cushion front cross tube are disposed between the two seat cushion side panel frames 2 and are rotatably connected to the seat cushion side panel frames 2, with the seat cushion rear cross tube 3 disposed rearward and the seat cushion front cross tube disposed forward; the lower end of the rear support arm is rotatably connected to the seat cushion bottom frame, and the upper end is fixedly connected to the seat cushion rear cross tube 3. The seat cushion assembly achieves forward lifting through the seat cushion forward lifting component 4;
[0018] The seat cushion front lifting assembly 4 includes a seat cushion lifting motor 6, a lower support plate 8 for the adjusting angle device, an adjusting angle device 9, an upper connecting plate 10 for the adjusting angle device, a front lifting support arm 11, and a synchronizing rod 12. The seat cushion lifting motor 6 is mounted on the lower support plate 8 for the adjusting angle device and drives the synchronizing rod 12 to rotate. There are two lower support plates 8 for the adjusting angle device, both mounted on the seat cushion bottom frame, and their front and rear ends are fixed to the seat cushion bottom frame by mounting bolts. There are two adjusting angle devices 9. One end of the angle adjuster 9 is mounted on the lower support plate 8 of the angle adjuster, and the other end is connected to the upper connecting plate 10 of the angle adjuster. It is located on the outside of the lower support plate 8 of the angle adjuster. The lower end of the front lifting arm 11 is rotatably connected to the upper connecting plate 10 of the angle adjuster, and the upper end is fixedly connected to the front horizontal tube of the seat cushion at the front end of the seat cushion side plate frame 2 or rotatably connected to the seat cushion side plate frame 2. The synchronizing rod 12 passes through the lower support plate 8 of the angle adjuster and is connected to the angle adjuster 9. It is rotatably connected to the lower support plate 8 of the angle adjuster.
[0019] The backrest assembly includes a backrest frame 5 and a backrest angle adjustment motor; wherein, the backrest frame 5 is installed between two seat cushion side plate frames 2, and a second angle adjuster 7 is provided at the connection point, and the angle of the backrest assembly is adjusted by driving the second angle adjuster 7 through the backrest angle adjustment motor.
[0020] It should be noted that in this embodiment, the backrest assembly can be any existing backrest assembly capable of angle adjustment. For details on how to achieve backrest angle adjustment, those skilled in the art can refer to existing technologies.
[0021] This invention uses a seat lifting motor 6 to drive a synchronous rod 12 and an angle adjuster 9 to rotate, increasing the angle between the lower support plate 8 (stationary) and the upper connecting plate 10 (moving) of the angle adjuster. The upper connecting plate 10 then lifts the front lifting arm 11, which is connected to the seat cushion side panel frame 2. The seat cushion side panel frame 2 is connected to the backrest frame 5, causing the seat cushion and backrest to rotate backwards simultaneously around the rear cross tube 3. This adjustment method causes the backrest to rotate backwards synchronously. Independent front lifting requires the backrest angle adjustment motor 7 to work in conjunction to ensure the passenger's backrest angle remains constant.
[0022] The three-row zero-gravity seats of this utility model are equipped with a long sliding rail 1 for adjusting the seat's fore-and-aft position. The lower support plate 8 of the adjusting mechanism is fixedly connected to the bottom frame of the seat cushion and then slidably connected to the long sliding rail 1 for adjusting the seat's fore-and-aft position. When it is necessary to adjust the third-row seats to a comfortable position according to the needs of the passengers, the fore-and-aft position is first adjusted using the long sliding rail 1 to increase the space between the third-row seats and the second-row seats. If tall passengers feel that their thighs lack support, the seat cushion can be adjusted to lift forward. The method for adjusting the seat cushion to lift forward is as follows:
[0023] The seat cushion assembly is lifted forward via the seat cushion front lifting component 4. The seat cushion front lifting component 4 drives the synchronous rod 12 and the angle adjuster 9 to rotate via the seat cushion lifting motor 6, thereby increasing the angle between the lower support plate 8 and the upper connecting plate 10 of the angle adjuster. The upper connecting plate 10 of the angle adjuster lifts the front lifting support arm 11, causing the seat cushion and backrest to rotate backward around the rear cross tube 3 of the seat cushion simultaneously.
[0024] The above describes specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
