The design starting point, the idea and the beneficial effects of the utility model adopting the technical scheme are as follows:
the existing movable armrests are often arranged on the seat in a T-shaped integral form, and the transverse parts for supporting the arms and the vertical parts serving as main body supports tend to move together, so that the flexibility required by the independent movement of the transverse parts is not achieved; so from the flexibility of the transverse component, the transverse component is separated from the vertical component as far as possible, thereby reducing the constraint of the vertical component to the transverse component and freeing the flexibility of the transverse component, and mainly comprising two points: firstly, an adjusting piece is arranged between the transverse component and the vertical component so as to enable the transverse component and the vertical component to move, and the transverse component can rotate around two perpendicular adjusting shafts of the adjusting piece, so that the movement direction of the transverse component is more, and the posture of the transverse component relative to the vertical component is more; secondly, the connection point of the transverse component and the vertical component is not in the middle of the transverse component but at one end of the transverse component, so that the transverse component can be flexibly changed towards the arm; therefore, after changing the thinking that the armrest is a whole, the transverse component and the longitudinal component have more definite functional positioning, namely, the longitudinal component is used as a main body support and can also be used for adjusting the height, and the transverse component is used as a component for supporting the arm and is flexibly and movably arranged on the longitudinal component, so that the arm can be reasonably and comfortably supported under more human postures.
Specifically, the bracket is movably arranged on the bracket through the adjusting piece and can rotate around the first adjusting shaft and the second adjusting shaft respectively, when the bracket rotates around the first adjusting shaft, one end of the bracket can rotate up and down, when the bracket rotates around the second adjusting shaft, one end of the bracket can rotate left and right, and the bracket can keep stable after each rotation; the bracket can rotate up and down around the first adjusting shaft after rotating left and right around the second adjusting shaft so as to present multiple postures, thus realizing more flexible adjustment and supporting arms under more human postures; when a user looks at the mobile phone, the brackets at the two sides of the seat can be folded inwards and tilted upwards after the structure is adjusted, so that the most comfortable support for the arms of the human body is provided.
The moving end in the initial state is positioned behind the connecting end, and is in a conventional armrest posture at the moment, namely, a user can place an arm on the bracket when sitting normally; in the adjusting state, the adjusting piece between the bracket and the bracket is similar to a joint, and only one end of the bracket is connected with the bracket, so that the bracket is similar to a flexibly movable support arm and can have more postures after rotating around the first adjusting shaft and the second adjusting shaft.
The movement end of the bracket is prevented from downward deflection in the initial state by the limiting table; the adjusting piece is limited by the limiting block, so that the bracket is prevented from rotating downwards excessively in the adjusting state. Therefore, the bracket rotates around the rotating column in the rotating process, after the limiting platform rotates away from the extension arm, the bracket can rotate up and down around the rotating shaft, and at the moment, the bracket can still rotate around the rotating column, so that the bracket has more postures to support arms of a human body in different scenes.
