Description
Technical Field
The invention relates to a damper, in particular to a rotary damper energy storage self-locking device with an energy storage function and a stepless locking function.
Background
Dampers are devices that provide resistance to movement and dissipate the energy of the movement. The damper has mature technology and is applied to various dampers in aerospace, military industry, automobiles, bridges and various telescopic, foldable and turnover covers. The rotary damper generally takes viscous oil as resistance, and the rotary damper can enable a product to obtain gentle mechanical motion, improve the quality of the product and prolong the service life of the product; the noise that produces when effectively reducing the product and using, with the cooperation of spring and various energy storage equipment, can make the more gentle and agreeable, the uniform velocity of motion, realize semi-automatization.
In the field of automobile parts, rotary dampers are mostly applied to semi-automatic accessories, such as semi-automatic rotating, stretching, lifting and the like. The rotary damper has a single damping function, and generally has a damping one-way or two-way function; if the device is installed in a semi-automatic mechanism, an energy storage device such as a spring needs to be additionally arranged, and particularly, the collocation of a control switch needs to be adjusted in lifting or stretching. Therefore, the technical scheme can diversify the functions of the rotary damper with single function, and can play a better role in the field of automobile parts and other fields.

Although the fixing member 302, the damper 303, the metal ring 304, the torsion spring 306 and the unlocking actuator 307 are combined together, the torsion spring 306 is used for holding the metal ring 304 to increase friction force to implement locking. Since the torsion spring 306 has a plurality of turns and is formed in a spiral shape, one end thereof is fixed to the fixing member 302, and the torsion spring is released by rotation of the other end thereof in the fixing groove 309 to perform unlocking. Since the torsion spring 306 is always in a clasped state, when the distance of rotation of the end connected to the fixing groove 309 during unlocking is not enough, the torsion spring 306 is not completely loosened on the side of the fixing member 302 and has friction with the metal ring 304. Therefore, the accuracy of the structure is not enough, the moving distance is large when unlocking, the lifting force is realized by the additionally arranged spring, and the structure is relatively complex.
The method is not the best, only the better, and is the motivation of innovation, and the innovation is the main factor of the continuous development of the society. A large number of rotary dampers are used in automobile parts designed and produced by people, but energy storage devices such as springs are required to be arranged on the rotary dampers to realize semi-automation. Except under the action of gravity. However, if the distance position of extension, lifting and rotation is controlled, a locking assembly is required to be installed.
