The invention discloses a magnetorheological damping type constant-speed opening and closing hinge robot. The magnetorheological damping type constant-speed opening and closing hinge robot comprises a first hinge arm, a second hinge arm, a torsional spring, a damping body, an overturning guide cylinder, a magnet driving sliding block, a push rod, a damping piston and a plurality of damping permanent magnets. Magnetorheological fluid is arranged in the damping body; a spiral guide groove is formed in the overturning guide cylinder; the magnet driving sliding block is provided with a connecting part and a plurality of sliding inclined wedge blocks made of ferromagnetic materials, and the push rod is movably clamped and matched with the spiral guide groove; the push rod is fixedly connected with the connecting part; a plurality of damping through holes are formed in the damping piston; and the multiple damping permanent magnets and a plurality of magnet mounting holes are formed in a one-to-one correspondence mode, and the multiple damping permanent magnets are slidably embedded in the multiple magnet mounting holes in a one-to-one correspondence mode and are correspondingly attached to the inclined surfaces of the multiple sliding inclined wedge blocks in a one-to-one correspondence mode. Real-time adjustment of the damping value is achieved, the damping value is matched with the torsion of the torsional spring, and therefore the constant-speed opening and closing action is achieved.
Description
technical field [0001] The invention relates to a magneto-rheological damping type uniform-speed opening and closing hinge robot. Background technique [0002] At present, most automatic opening and closing hinges are reset by torsion springs or springs, and the speed of the opening and closing hinges is adjusted in conjunction with the damping effect of the hydraulic damper to obtain relatively smooth hinge opening and closing actions. According to the elastic force formula F=KX of the spring, it can be seen that the elastic force of the spring is linearly related to the degree of compression. The greater the degree of compression, the greater the elastic force, and the faster the hinge opens. However, the damping of the existing dampers for hinges cannot be adjusted in real time with the spring force, resulting in that the opening and closing of the hinge cannot be performed at a uniform speed. Contents of the invention [0003] The object of the present invention is to...
