The iron core 202b of each magnet assembly 202 is wound with the wound magnetic coil 202c, and the power supply of the wound magnetic coil 202c to which one or more magnet assemblies 202 is or is not supplied and the current strength of each wound magnetic coil 202c are determined by the central control unit ECU of the automobile, so that the slip speed and the slip distance of the mass 302 can be controlled by effectively coordinating and scheduling the power supply of the wound magnetic coils 202 c. The height signal that the height sensor 104 of cooperation installation on frame 100 passed out is as the feedback, can realize the intelligent closed loop quality control of whole car automobile body, makes up the defect in intelligent regulation and control of current automobile body frame module.
The magnet assembly 202 can attract the mass block 302 after being electrified, the material of the mass block 302 is preferably iron, the plurality of slidable mass blocks 302 can improve the circumferential mass distribution of the vehicle body, wherein the mass block 302 sliding in the short-side beam 103 is beneficial to improving various dangerous tendencies of the vehicle body such as rolling, sliding and yawing, and the mass block 302 sliding in the long-side beam 102 is beneficial to improving the longitudinal swinging of the vehicle body, such as the longitudinal fluctuation tendency of a cab and a carriage, so that the stability of the vehicle body can be better improved, the defect of mass distribution adjustment can be improved on the basis of the traditional vehicle frame, and meanwhile, the springs 304 between the isolation plates 303 can also reduce the impact energy to a certain extent, and further reduce the possibility of the rollover tendency.

For medium and small enterprises, the manufacturing cost is controllable, the vehicle body driving safety is improved, meanwhile, the cost and the period of rectification are reduced, and the market potential is huge.
It should be noted that the balance principle of the device of the present invention is as follows:
first, the predetermined implementation is a pickup truck with a cabin, as shown in fig. 7, where the balance line is maintained on the center line of the body of the truck frame 100. Then, considering from the overturning direction of the vehicle body, the left and right masses of the vehicle body on two sides of the center line are respectively M1 and M2, the mass of the mass block 302 is Δ M, the gravitational potential energy on two sides is respectively M1g and M2g, and the total initial gravitational potential energy is M1g h + M2g h, wherein g is the gravitational acceleration, and h is the height of the vehicle frame 100 from the ground. When a limit rollover tendency occurs, due to the adjusting action of the mass blocks 302, the additional mass induced by the shifted mass blocks 302 is k × Δ m, and under the rollover action, the reversed gravitational potential energy Mr is (m1-k × Δ m) g (L + Δ L1) + (m2+ k Δ m) g (L- Δ L2), wherein Δ L1 and Δ L2 are changes of the distances between the left and right side frames 100 and the ground, and the energy difference dissipated by the gravitational potential energy is-k Δ m × g 1-k Δ m g Δ L2 compared with the initial frame 100 state, namely equivalent to the reversed gravitational energy dissipated by the shifted mass blocks 302, so that the vehicle can rapidly reach an equilibrium state. The rebalancing process in the front-rear direction and the roll energy reduction mechanism in the left-right direction of the frame system shown in fig. 8 are the same, and will not be described again here.
When a vehicle is toppled to approach to side turning, the height sensor 104 on the vehicle frame 100 senses the height change of left and right or front and rear wheels, the central control unit ECU of the vehicle senses a height signal transmitted by the height sensor 104 and judges that the mounting vertical displacement value of the vehicle frame 100 exceeds the standard, the vehicle-mounted pump body lifts the pressure in each air bag 305a, the air bags 305a inflate the damper 305b through the air pipeline, the damper 305b expands and drives the baffle 306 to move, and the movement distance of the mass block 302 at the moment is increased. In addition, the central control unit ECU of the automobile controls the energization of the magnetic coil 202c, the iron core 202b wrapped on the supporting column 202a generates magnetic force on the magnet assembly 202 under the action of the energized magnetic coil 202c, pulls the mass block 302 to move, and by the mass transfer and the flat-back rollover trend, after the central control unit ECU of the automobile judges that the height signal transmitted by the height sensor 104 is reasonable, the current on the magnetic coil 202c is cut off, the magnetic force on the magnet assembly 202 disappears, meanwhile, the pressure of each air bag 305a is reduced by the vehicle-mounted pump body, the damper 305b contracts and drives the baffle 306 to return to the initial position, the baffle 306 further drives the mass block 302 to return to the initial position, and the balancing process is finished.
It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
