For ease of understanding stressing conditions and the motion process of each parts when describing described movable armrest board work below in conjunction with Fig. 2, Fig. 5 to Fig. 8:
See also Fig. 5:
When board 101, fixedly outside plate 102, connector 103, fixedly inner panel 104, direction turning piece 105, elastic component 106, Metallic rod 107, after being assembled together, limited block 109 and wear washer 110 combinations obtain movable armrest board as shown in Figure 5, during normal operation, the upper surface of board 101 is subjected to self gravitation or weight pressure and is sagging, without other active force the time, described movable armrest board can rotate centered by Metallic rod 107 in the counterclockwise direction, at this moment, the limit body 1071 of described Metallic rod 107 cooperates the stopper slot 1081 of described handrail 108 to use, can produce a torsion along clockwise direction to described limit body 1071, so that the board 101 of described movable armrest board remains on horizontal level, for the user normally.
See also Fig. 6:
When described movable armrest board normal operation, be that board 101 is when being positioned at horizontal level, described elastic component 106 is subjected to force compresses, when decrement surpasses the elastic characteristic angle of elastic component 106 itself, the rotation that can not rebound of described board 101, namely this moment, the normal operation of movable armrest board was not rotated.
See also Fig. 7:
When described movable armrest board folding, described board 101 will rotate 155 degree together with described fixedly inner panel 104, described elastic component 106 opens, thereby driving board 101 rotates, 155 degree of described rotation are to be subjected to the in advance designing institute restriction of fixing inner panel 104, can also be designed to other angle when needed.
The elastic force that elastic component 106 discharges is larger, so that described fixedly inner panel 104 produces loud noise when contacting with described direction turning piece 105, this moment, described limited block 109 played the effect of buffer spring, realized the purpose of vibration silencer in order to prevent larger elastic force.
See also Fig. 8:
Can horizontally rotate 155 degree when the above has illustrated described board 101 folding, with the time simultaneously, described Metallic rod 107 also can be rotated 90 degree along clockwise direction.And describedly horizontally rotate 155 degree and described to rotate along clockwise direction two actions of 90 degree separate, Figure 8 shows that the movable armrest board design sketch after the folding.
Among the utility model embodiment, rotating mechanism comprises: fixedly inner panel 104, direction turning piece 105, elastic component 106, Metallic rod 107 and handrail 108, wherein fixedly the rotating mechanism of inner panel 104, direction turning piece 105 and elastic component 106 formations is used for horizontally rotating of movable armrest board, and the rotating mechanism that Metallic rod 107 and handrail 108 consist of is used for the circumference twisting of described movable armrest board, has simplified the structure of movable armrest board; Cooperate the connection bit 1041 of the connecting hole 1061 of described elastic component 106, described fixedly inner panel 104, the limit body 1071 of described Metallic rod 107 and the stopper slot 1081 of described handrail 108, the precise positioning when having realized described movable armrest board rotation.Therefore, the utility model can be simplified manufacturing, the assembling operation of movable armrest board, so that the user obtains better movable armrest board experience, increases simultaneously the reliability of movable armrest board.
