Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a zero-gravity seat frame. Background Technology

[0002] Traditional chair designs, whether office chairs, car seats, or airplane seats, mostly only consider basic support functions. For example, common office chairs are primarily designed to accommodate people sitting for long periods of time, focusing on basic support for the spine and hips from the backrest and seat cushion. However, after prolonged use, people still experience fatigue in their lower back, back, and hips. This is because traditional chairs do not adequately consider the pressure distribution of the body in different postures, causing some areas of the body to bear greater pressure, hindering blood circulation, and thus leading to discomfort.

[0003] While existing zero-gravity seats have improved the distribution of pressure on the human body to some extent, they still have many shortcomings. On the one hand, in terms of structural design, some zero-gravity seats use complex and large mechanical structures to achieve zero-gravity simulation. This not only increases the overall weight and cost of the seat, but also limits its application in some space-constrained scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a zero-gravity seat frame, which aims to solve the problem that the existing car seats are relatively complex and therefore have high production costs.

[0005] To achieve the above objectives, in a first aspect, this utility model provides a zero-gravity seat frame, including a seat cushion frame assembly, a rear cross tube, a backrest frame assembly, a leg support assembly, two front transmission assemblies, a motor assembly, a toothed plate, a first rear support leg, a rear support rod, a second rear support leg, and an electric slide rail.

[0006] The rear cross tube is mounted on the seat cushion frame assembly, the backrest frame assembly is mounted on the seat cushion frame assembly, the leg support assembly is mounted on the side of the seat cushion frame assembly away from the backrest frame assembly, the two front drive assemblies are respectively mounted on the front end of the seat cushion frame assembly, the motor assembly is mounted on the seat cushion frame assembly, the toothed plate is fixedly connected to the rear cross tube and meshes with the motor assembly, the first rear support leg is fixedly connected to the toothed plate and fixedly connected to the electric slide rail, the motor assembly is mounted on the seat cushion frame assembly, the rear support rod is fixedly connected to the rear cross tube, the second rear support leg is fixedly connected to the rear support rod and fixedly connected to the electric slide rail.

[0007] The seat cushion frame assembly includes a seat cushion frame body, two side plates, and two lower fixing plates. The seat cushion frame body is connected to the leg support assembly. The two side plates are fixedly connected to the seat cushion frame body and rotatably connected to the rear cross tube, respectively. The two lower fixing plates are fixedly connected to the two side plates and are located on the two side plates, respectively.

[0008] The backrest frame assembly includes two angle adjusters, a backrest frame body, a drive shaft, and a backrest adjustment motor. The fixed sides of the two angle adjusters are respectively fixedly connected to the two lower fixed plates. The backrest frame body is connected to the rotating sides of the two angle adjusters. The backrest adjustment motor is mounted on the backrest frame body. The drive shaft is connected to the two angle adjusters and fixedly connected to the output end of the backrest adjustment motor.

[0009] The front transmission assembly includes a connecting rod, a driven rod, and a front support foot. The connecting rod is rotatably connected to the side plate and is located on one side of the side plate. The driven rod is rotatably connected to the connecting rod and is located on the side of the connecting rod away from the side plate. The front support foot is rotatably connected to the driven rod and is fixedly connected to the electric slide rail.

[0010] The zero-gravity seat frame further includes a mounting bracket and a limiting rod. The toothed plate has a limiting groove. The mounting bracket is fixedly connected to the side plate and rotatably connected to the output end of the motor assembly, and is located on one side of the side plate. The limiting rod is fixedly connected to the mounting bracket and the side plate, and is located within the limiting groove.

[0011] Secondly, a method for adjusting the tilt angle of a zero-gravity seat frame, used for the zero-gravity seat frame described in the first aspect, includes the following steps:

[0012] When the motor assembly is started, the gears of the motor assembly drive the gear plate to rotate, and the gear plate drives the seat frame assembly to move away from the vehicle body.

[0013] The rear support rod and the two front drive components rotate to support the seat frame assembly until the seat frame assembly is adjusted to the preset angle;

[0014] At the same time, the backrest adjustment motor drives the transmission shaft to adjust the backrest frame body on the two angle adjusters to the preset angle.

[0015] This utility model discloses a zero-gravity seat frame. The seat cushion frame assembly provides installation conditions for the rear cross tube, the backrest frame assembly, the leg support assembly, the two front drive assemblies, and the motor assembly. The electric slide rail connects to the gear plate and the rear support rod via the first and second rear support feet. When seat adjustment is needed, the motor assembly is activated. The motor assembly drives the gear plate to rotate via gears, causing the seat cushion frame assembly to move away from the vehicle body. Simultaneously, the rear support rod and the two front drive assemblies rotate to support the seat cushion frame assembly until it reaches a preset angle. At this point, the backrest frame assembly activates to adjust the backrest to the corresponding angle, ensuring the human body is in the most comfortable posture. The electric slide rail allows for fore-and-aft adjustment of the seat cushion frame assembly. Compared with other technologies, this utility model has a simpler structure, is easier to arrange, has lower cost, is easier to maintain, and provides sufficient space and installation points for other types of seats and higher-configuration seats to add other functional modules, thus solving the problem of high production costs due to the complexity of existing car seats.

[0032] In this embodiment, the angle of the backrest frame body 13 can be adjusted by the two angle adjusters 12. The backrest adjustment motor 15 can drive the transmission shaft 14 to rotate, and the rotation of the transmission shaft 14 can drive the two angle adjusters 12 to rotate, thereby realizing the angle adjustment of the backrest frame body 13.

[0033] Furthermore, the front transmission assembly includes a connecting rod 16, a driven rod 17, and a front support foot 18.

[0037] When seat adjustment is required, the motor assembly 3 is activated. The motor assembly 3 drives the gear plate 4 to rotate via gears. The gear plate 4 moves the seat cushion frame body 9 away from the vehicle body. Simultaneously, the rear support rod 6, the two front connecting rods 16, and the two driven rods 17 rotate to support the seat cushion frame body until it is adjusted to a preset angle. At the same time, the backrest adjustment motor 15 is activated, driving the transmission shaft 14 to rotate. The transmission shaft 14 drives the two angle adjusters 12 to rotate. The angle adjuster 12 drives the two backrest frame bodies 13 to rotate, adjusting the backrest frame bodies 13 to the corresponding angle, thereby ensuring that the human body is in the most comfortable posture. The electric slide rail 8 can adjust the seat cushion frame body 9 back and forth. Compared with the technology, this utility model has a simple structure, is easy to arrange, and has a lower cost. The components of this utility model can be used for other structural seats, leaving enough space and installation points for other types of seats and higher configuration seats to add other functional modules, thereby solving the problem that the existing car seats are relatively complex and have high production costs.

[0038] Please see Figure 4 Secondly, a method for adjusting the tilt angle of a zero-gravity seat frame, used for the zero-gravity seat frame described in the first aspect, includes the following steps:

[0039] S1 starts the motor assembly 3, the gear of the motor assembly 3 drives the gear plate 4 to rotate, and the gear plate 4 drives the seat frame assembly to move away from the vehicle body.

[0040] Specifically, when the seat needs to be adjusted, the motor assembly 3 is activated. The motor assembly 3 drives the gear plate 4 to rotate through the gears, and the gear plate 4 drives the seat cushion frame body 9 to move away from the vehicle body.

[0041] The S2 rear support rod 6 and the two front drive components rotate to support the seat frame assembly until the seat frame assembly is adjusted to the preset angle.

[0042] Specifically, the rear support rod 6, the two front connecting rods 16, and the two driven rods 17 rotate simultaneously to support the seat cushion frame body 9 until the seat cushion frame body 9 is adjusted to a preset angle.

[0043] S3 simultaneously drives the backrest adjustment motor 15 to operate, which in turn drives the transmission shaft 14 to adjust the backrest frame body 13 on the two angle adjusters 12 to the preset angle.

[0044] Specifically, the backrest adjustment motor 15 starts simultaneously, and the backrest adjustment motor 15 drives the transmission shaft 14 to rotate. The transmission shaft 14 drives the two angle adjusters 12 to rotate, and the two angle adjusters 12 drive the two backrest frame bodies 13 to rotate, so as to adjust the backrest frame bodies 13 to the corresponding angle, thereby ensuring that the human body is in the most comfortable posture.

[0045] The beneficial effects of this utility model are as follows:

[0046] I. Compared with other known technologies, the zero-gravity seat of this utility model has a simple structure, is easy to arrange, and has a lower cost. In this utility model, each component can be used for other structural seats. The structure is simple and easy to maintain. It provides sufficient space and installation points for other types of seats and higher configuration seats to add other functional modules.

[0047] Second, the installation position of the zero-gravity seat motor of this utility model is basically the same as that of the height adjustment motor, which enables this zero-gravity seat to be used with other six-way seats and allows the zero-gravity seat to share a platform with ordinary four-way / six-way seats, greatly reducing product development costs.

[0048] Third, compared with the traditional zero-gravity seat, the new model is arranged further back, which frees up the front space of the seat and reduces the difficulty of arrangement. The traditional zero-gravity seat is arranged in front, but the front of the seat MCU and leg support motor are also arranged, which makes the front structure too compact and difficult to arrange and install. In the new zero-gravity seat, the motor is arranged in the high position of the traditional six-way seat, at the rear of the seat cushion, which provides ample front space for the arrangement of other functions.

[0049] The above-disclosed embodiments are merely preferred embodiments of the zero-gravity seat frame of this utility model, and should not be construed as limiting the scope of this utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes according to the claims of this utility model still fall within the scope of this utility model.
