As shown in fig. 1 to 6, an embodiment of the present utility model will be described in detail:

a damping chassis comprises a chassis body 1, a fixed shaft 2, a supporting leg frame 3 and a torsion spring 4; the lower extreme of quick-witted case body 1 rear side is provided with fixed axle 2, and landing leg frame 3 rotates on fixed axle 2, and torsional spring 4 cover is established on fixed axle 2, and the both ends top tightly landing leg frame 3 and quick-witted case body 1 respectively, makes the upper end top tightly of landing leg frame 3 the lower extreme of quick-witted case body 1, and the lower extreme backward slope of landing leg frame 3.

The working state of the embodiment is that the front end of the chassis body 1 and the support leg frame 3 are simultaneously supported on the ground, when the chassis is impacted or vibrated, the front end of the chassis body 1 keeps in a state of contacting with the ground, the rear end of the chassis body 1 can press down the support leg frame 3, so that the support leg frame 3 can rotate on the fixed shaft 2 against the elastic force of the torsion spring 4, the impact or vibration is buffered, and after the impact or vibration, the chassis is automatically restored to the original state through the elastic force of the torsion spring 4, and then the protection of electric elements in the chassis body 1 is formed;

when the support leg frame 3 rotates, the contact part of the support leg frame 3 and the ground or the contact part of the chassis body 1 and the ground can slide with the ground, so that a space is provided for the rotation of the support leg frame 3, and meanwhile, the support leg frame 3 is further buffered by friction force with the ground.

Further:

by arranging another fixed shaft 2 at the lower end of the front side of the case body 1 and rotating another leg frame 3 on the fixed shaft 2, another torsion spring 4 is arranged between the leg frame 3 and the case body 1.

The working state of the embodiment is that the chassis body 1 is supported on the ground through the two leg frames 3, when the chassis is impacted or vibrated, the chassis body 1 can downwards press the two leg frames 3, so that the two leg frames 3 respectively overcome the elastic force of the torsion springs 4 and rotate on the two fixed shafts 2, the impact or vibration is buffered, and after the impact or vibration, the chassis body automatically returns to the original state through the elastic force of the torsion springs 4, and then the protection of electric elements in the chassis body 1 is formed;

also, when the two leg frames 3 are rotated, the contact part of the leg frames 3 and the ground can slide with the ground, so that space is provided for the rotation of the leg frames 3, and meanwhile, the rotation of the leg frames 3 is further buffered by friction force with the ground.

Further, the two support leg frames 3 are in a front-back symmetrical state, so that the whole machine is attractive, and when the machine case is impacted or vibrated, the two support leg frames 3 can uniformly and synchronously rotate under the stress, vibration generated by the inclination of the machine case is reduced, and further protection of electric elements is formed.

Further:

the left and right sides of the lower end of each leg frame 3 are respectively provided with a roller 5 in a rotating way; the outer end of each roller 5 is provided with a rubber layer; a cavity is arranged in the rubber layer.

Through the arrangement of the four rollers 5, the chassis is supported on the ground through the four rollers 5, and when the chassis is impacted or vibrated, the two support leg frames 3 overcome the elastic force of the torsion springs 4 and rotate, the direct sliding between the two support leg frames 3 and the ground is replaced through the rolling of the four rollers 5 on the ground, so that the smoothness of the chassis for impact or vibration buffering is improved, and the adaptability of the chassis to the placement environment is improved; meanwhile, through the arrangement of the rubber layer, the friction force between the roller 5 and the ground is improved, so that further buffering of the rotation of the support leg frame 3 is conveniently ensured through the friction force; and the cavity is formed in the rubber layer, so that the rubber layer is deformed under the pressure of the chassis when contacting with the ground, the contact area between the rubber layer and the ground is increased, the friction between the roller 5 and the ground is increased, and the support leg frame 3 is further guaranteed to be buffered by the friction.

Moreover, through the setting of four gyro wheels 5, be convenient for make quick-witted case roll movement, improve the moving efficiency.
