[0088] An embodiment of the utility model provides a car, comprising a seat frame.

[0089] As an example, the seat frame includes a front cross tube 10, a seat pan 11 and a frame assembly; the front cross tube 10 is set between the two support structures of the frame assembly to form an installation position, and the seat pan 11 is installed at the installation position, so that the installation of the chassis 11 is more convenient and stable. The frame assembly includes a connecting beam 7 and two support structures; during installation, the two ends of the connecting beam 7 are respectively connected between the slide rail assemblies 2 of the two support structures, so that an integral three-dimensional structure is formed by the connection, and the two support structures cooperate to facilitate the adjustment of the posture of the frame assembly to achieve the adjustment of the posture of the seat pan to meet the use requirements. The frame assembly includes a connecting beam 7 and two support structures; the support structure can be applied to the frame assembly to adjust the posture of the frame assembly. The frame assembly can be applied to many products to adjust the overall use posture of the product. For example, the frame assembly can be applied to the seat frame to adjust the use posture of the seat. During installation, the two ends of the connecting beam 7 are respectively connected between the slide rail assemblies 2 of the two support structures, so that an integral three-dimensional structure is formed by the connection, and the two support structures cooperate to facilitate the adjustment of the posture of the frame assembly. The support structure specifically includes a support plate 1, a slide rail assembly 2, a first connecting rod 3, a second connecting rod 4 and a third connecting rod 5; during installation, the support plate 1 and the slide rail assembly 2 are arranged at intervals, the slide rail assembly 2 is used as a support reference, the support plate 1 is used to install the supported member, the first end of the first connecting rod 3 is movably connected to the first end of the slide rail assembly 2, and the second end of the first connecting rod 3 is movably connected to the first end of the support plate 1; the first end of the second connecting rod 4 is movably connected to the second end of the slide rail assembly 2, the second end of the second connecting rod 4 is movably connected to the first end of the third connecting rod 5, and the second end of the third connecting rod 5 is movably connected to the second end of the support plate 1; in this way, the support plate 1, the slide rail assembly 2, the first connecting rod 3, the second connecting rod 4 and the third connecting rod 5 form five movable connection points, which can increase the variables in the support structure, thereby reducing the restrictions between the connecting rods, improving the adjustment effect, and facilitating the adjustment of the posture of the support structure. When the second connecting rod 4 and the third connecting rod 5 remain stationary, the angle between the two remains unchanged, and the first connecting rod 3 rotates, the height difference between the first end of the slide rail assembly 2 and the first end of the support plate 1 will change, and the distance between the support plate 1 and the slide rail assembly 2 will change accordingly, so that the height of the support plate 1 can be adjusted by changing the posture of the first connecting rod 3, so as to adjust the height of the supported member. The support structure also includes a transmission assembly 6, which movably connects the transmission assembly 6 with the second end of the second connecting rod 4 and the first end of the third connecting rod 5. When the first connecting rod 3 remains stationary, the angle between the second connecting rod 4 and the third connecting rod 5 can be adjusted by the transmission assembly 6 to adjust the inclination angle of the support plate 1, so as to adjust the posture of the supported member. Among them, the transmission assembly 6 can be set on the support plate 1. When the transmission assembly 6 is not working, the support plate 1, the third connecting rod 5 and the transmission assembly 6 cooperate to form a triangular structure, which can improve the stability of the support structure.

[0090] The seat frame in this example can adjust the height and posture of the frame assembly through the supporting structure of the frame assembly, which can realize the combination of driver posture and zero-gravity posture and ensure the safety of occupants and drivers. This is because the height adjustment and angle adjustment in the seat frame can be operated separately in principle, and either driving posture or zero-gravity posture can be realized at the same time.

[0091] This example also includes the vehicle computer and the seat controller; when the vehicle computer detects that the door on the corresponding side of the seat frame is opened, and the sensor detects that there is no occupant in the seat frame, the vehicle computer sends a signal to the seat controller to execute the occupant boarding and welcoming. The supporting structure of the seat frame automatically adjusts the frame assembly and the backrest assembly 12 to the welcoming mode position; when the vehicle computer detects that the door on the corresponding side of the seat is not opened or the sensor detects that there is an occupant on the seat frame, if one of the two conditions is met, it is judged that no occupant is on the vehicle, the welcoming mode is not entered, and the seat frame does not move; when the occupant has finished boarding, and the vehicle computer detects that the engine / motor is running, the vehicle computer will automatically adjust the frame assembly and the backrest assembly 12 to the welcoming mode position. When the speed is zero, the vehicle computer sends a signal to the seat controller, and the seat frame enters the standby or rest mode. The seat frame does not make any automatic movements. At this time, if the space conditions permit, the zero gravity state can be started with one button, and the frame assembly and the backrest assembly 12 can be adjusted to any achievable position through the support structure of the seat frame according to human-machine requirements; when the vehicle computer detects that the engine / motor speed is not zero, the vehicle computer will send a signal to the seat controller, and the seat frame enters the driving mode; when the vehicle speed is detected to be lower than 40KM / H (this data can be adjusted according to safety requirements), the vehicle computer sends an indication signal, and the seat frame enters Low-speed driving mode, at this time, the one-key zero-gravity start mode can be executed, and the support structure of the seat frame can adjust the frame assembly and the backrest assembly 12 to any human-machine required position; when the vehicle speed is detected to be higher than 40KM / H (this data can be adjusted according to safety requirements), the vehicle computer sends an indication signal to the seat controller, and the seat enters the high-speed driving mode. At this time, the one-key zero-gravity function will not be started, and the backrest assembly 12 will be restricted when adjusted to a certain angle (specifically defined according to safety requirements), and the maximum backrest angle cannot be reached. The frame assembly angle will be restricted when adjusted to a certain angle (specifically defined according to safety requirements) , and the maximum angle cannot be reached; when the sensor detects that there is an occupant in the seat, and detects that the door on the side corresponding to the seat frame is open, and at the same time detects that the vehicle is turned off, the vehicle computer determines that the occupant is about to leave the vehicle, and the vehicle computer sends a signal to the seat controller, and the seat frame enters the departure mode, and the supporting structure of the seat frame automatically moves the frame assembly and the backrest assembly 12 to the departure mode position; when the sensor detects that there is no occupant in the seat frame, or detects that the door on the side corresponding to the seat frame is not open or detects that the vehicle is not turned off, if one of the three conditions is met, the vehicle computer determines that it is not in departure mode, and the seat frame will not move.
