[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 4As shown, a climbing vehicle seat with automatic balance adjustment comprises a frame, a plurality of seats and a synchronous adjustment mechanism are fixed on the frame, wherein an angle sensor is fixedly arranged under the seat surface of one of the seats, and the angle sensor and the seat surface are in the same horizontal plane; the synchronous adjustment mechanism comprises a driving device, a linkage rod, a plurality of connecting shafts and a rotating shaft with the same number as the connecting shafts, the rotating shaft comprises a central shaft and a hexagonal shell sleeved outside the central shaft, a plurality of seats are fixedly arranged on the shell, one end of the connecting shaft is vertically fixedly connected to the rotating shaft, and the other end is fixed to an F-type fixing piece, and the F-type fixing piece is hinged to the same side of the linkage rod at an equal distance, and a shoulder extending from one of the F-type fixing pieces is hinged to the driving device, and the synchronous adjustment mechanism is used to automatically adjust the balance of the plurality of seats according to the feedback of the angle sensor.

[0022] The above technical scheme is adopted, by setting the frame, seat, synchronous adjustment mechanism and angle sensor for coordinated use, the angle sensor is installed under the seat surface of the seat and ensured to be in the same horizontal plane to detect the state of the seat, when the seat is in a tilted state, an adjustment signal is transmitted to the synchronous adjustment mechanism, the synchronous adjustment mechanism uses the driving device, linkage rod, connecting shaft and rotating shaft in coordination, and uses the connecting shaft to convert the telescopic movement of the driving device into the circular rotation of the rotating shaft, so that the seat installed on the rotating shaft produces a forward and backward swinging movement, and then ensures that the seat is in a horizontal state, and the linkage rod can be used to make the front and rear rows of seats move together, complete the synchronous adjustment of the tilt state of the multiple rows of seats, so that the multiple rows of seats always remain in a horizontal state, and when the climbing vehicle tilts during operation, the seat inclination angle can be automatically adjusted to compensate, so that the angle between the seat surface and the horizontal plane is kept within a reasonable range, thereby improving the riding comfort and sightseeing experience of passengers.

[0023] like Figure 1 and Figure 2 As shown, the number of the seats is an integer multiple of the number of the rotation axes.

[0024] By adopting the above technical solution, the power of the driving device can be maximized by setting the number of seats to an integer multiple of the number of rotating shafts. However, when the number of seats exceeds the limit, it is necessary to add corresponding driving devices.

[0025] like Figure 3 and Figure 4 As shown, the seat also includes a seat back and a seat frame, the seat surface and the seat back are fixedly arranged on the seat frame, a bayonet is arranged at the bottom of the seat frame, and the bayonet is clamped on the shell of the rotating shaft.

[0026] By adopting the above technical solution, a bayonet is provided, and the shape of the bayonet matches the hexagonal shape of the shell, so that a tight snap fit can be achieved, thereby better converting the rotation of the rotating shaft into the forward and backward swinging of the seat.

[0027] like Figure 1 As shown, two ends of the central axis of the rotating shaft are connected with triangular fixing frames, and one end of the fixing frame away from the rotating shaft is fixedly connected to the vehicle frame.

[0028] By adopting the above technical solution and providing a triangular fixing frame, the seat can be firmly fixed on the vehicle frame by utilizing the stability of the triangle.

[0029] like Figure 1 , Figure 2 As shown, the driving device is an electric hydraulic push rod, the driving device is electrically connected to a power source, connected to the angle sensor signal, and fixedly connected to the vehicle frame.

[0030] By adopting the above technical solution, the driving device is set as an electric hydraulic push rod and electrically connected to the power supply and the angle sensor signal. After the angle sensor detects that the seat is in a tilted state, it transmits a signal to the driving device, and the driving device starts working to adjust the seat state to a horizontal state.

[0031] like Figure 2 As shown, the frame is also provided with a limiting groove for limiting the movement direction of the connecting shaft.

[0032] By adopting the above technical solution and providing the limit groove, the connecting shaft can be restricted to swing back and forth only in the limit groove, thereby converting the telescopic motion of the driving device into the circular motion of the rotating shaft.
