The floor assembly 180 includes a floor 181 and a pedal mechanism installed on the top of the floor, and the pedal mechanism is composed of a brake system 182 and a throttle system 183;

[0024] The gas spring 110 comprises: a pressure rod 112 and a pressure cylinder 111; the pressure rod 112 can move axially relative to the pressure cylinder 111; wherein the gas spring 110 is arranged along the longitudinal direction of the vehicle body;

[0026] The gas spring connecting ear 130 is fixed to the bottom of the base plate 181; an M8 protruding threaded rod 114 is processed at the free end of the pressure cylinder 111, and the threaded rod 114 passes through the gas spring connecting ear 130. The end of the threaded rod 114 is fixed by an M8 nylon anti-loosening nut, so that the gas spring 110 is fixedly connected to the bottom of the base plate 181 through the gas spring connecting ear 130.

[0027] Based on the characteristics of the controllable gas spring, the force of the gas spring 110 is used to push the gas spring fixing lug 120 to quickly adjust the base plate assembly 180 .

[0028] Two optical axes 150 are arranged along the longitudinal direction of the vehicle body, the two optical axes 150 are located below the bottom plate 181 and are respectively arranged on both sides of the gas spring 110;

[0029] The optical axis hanging ear 160 is divided into two parts, the upper and lower parts, and is connected to the two ends of the optical axis 150 by upper and lower clamping. The two ends of the optical axis 150 are connected to the frame through the optical axis hanging ear 160 respectively;

[0030] A frame welding component 170, which is welded to the frame, and the frame welding component 170 is connected to the optical axis hanging ear 160 by bolts;

[0031] The optical axis hanging ears 160 are connected to the two ends of the optical axis 150 by upper and lower clamping, and the two ends of the optical axis 150 are respectively fixedly connected to the frame through the connection between the optical axis hanging ears 160 and the frame welding component 170;

[0032] Two sets of linear sliders 140 are fixedly mounted on the bottom of the base plate 181 and are matched and mounted on the two optical axes 150 one by one, so that the base plate assembly 180 can only make forward and backward adjustment movements along the optical axis 150, limiting the movement direction of the base plate assembly 180.

[0033] like Figure 2 As shown, the utility model provides a quick adjustable mechanism for the floor assembly of an FSEC racing car. The pull wire (not shown in the figure) of the controllable gas spring 110 is used as a switch to adjust the gas spring 110, and is used to control the use state of the gas spring 110; the number of each group of the linear sliders 140 is two, and the four linear sliders 140 are installed at the four corners of the floor 181 by bolts. The linear sliders 140 are embedded with sliding bearings, so that the floor assembly 180 is evenly stressed and moves forward and backward smoothly; the number of the optical axis hanging ears is four; the number of the frame welding parts 170 is four, which are arranged at the four corners of the adjustment mechanism; the frame welding parts 170 and the gas spring fixing hanging ears 120 are welded to the frame, so that the quick adjustable mechanism of the floor assembly of the entire FSEC racing car is fixed on the car.

The optical axis 150 can also be replaced with other components that can slide forward and backward.

[0036] The quick adjustable mechanism of the bottom plate assembly of the FSEC racing car provided by the utility model is designed by utilizing the characteristics of the controllable gas spring. The force of the gas spring 110 pushes the gas spring fixing lug 120, thereby driving the bottom plate assembly 180 to move forward and backward with the gas spring 110. The connection mode of the optical axis 150 and the linear slider 140 in the adjustable mechanism makes the bottom plate assembly 180 evenly stressed and can only move forward and backward. Compared with the common electric adjustment of the lead screw on the field at this stage, the adjustable mechanism provided by the utility model can adjust the bottom plate assembly 180 forward and backward more conveniently and quickly, and the coaxiality requirement is low during installation.
