For ease of understanding, stressing conditions and the motion process of each parts while describing described movable armrest board work below in conjunction with Fig. 2, Fig. 5 to Fig. 8:
Refer to Fig. 5:
When board 101, fixing outside plate 102, connector 103, fixing 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, when normal work, the upper surface of board 101 is subject to self gravitation or weight pressure and is sagging, when without other active force, described movable armrest board can rotate in the counterclockwise direction centered by Metallic rod 107, now, the limit body 1071 of described Metallic rod 107 coordinates the stopper slot 1081 of described handrail 108 to use, can produce a torsion along clockwise direction to described limit body 1071, make the board 101 of described movable armrest board remain on horizontal level, for user normally.
Refer to Fig. 6:
When described movable armrest board is normally worked, be that board 101 is while being positioned at horizontal level, described elastic component 106 is subject to force compresses, when decrement exceedes the elastic characteristic angle of elastic component 106 itself, the rotation that can not rebound of described board 101, i.e. the now normal work of movable armrest board is not rotated.
Refer to Fig. 7:
In the time of described movable armrest board folding, described board 101 will rotate 155 degree together with described fixing inner panel 104, described elastic component 106 opens, thereby drive board 101 to rotate, 155 degree of described rotation are limited by the design in advance of fixing inner panel 104, can also be designed to when needed other angle.
The elastic force that elastic component 106 discharges is larger, and in order to prevent that larger elastic force from producing loud noise when described fixing inner panel 104 is contacted with described direction turning piece 105, now described limited block 109 has played the effect of buffer spring, realizes the object of vibration silencer.
Refer to Fig. 8:
While described board 101 folding being described above, can horizontally rotate 155 degree, with time simultaneously, described Metallic rod 107 also can be rotated 90 degree along clockwise direction.And described in 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 folding.
In the embodiment of the present invention, rotating mechanism comprises: fixing inner panel 104, direction turning piece 105, elastic component 106, Metallic rod 107 and handrail 108, wherein fix rotating mechanism the horizontally rotating for movable armrest board that inner panel 104, direction turning piece 105 and elastic component 106 form, and the rotating mechanism that Metallic rod 107 and handrail 108 form is for the circumference twisting of described movable armrest board, simplify the structure of movable armrest board; Coordinate connection bit 1041, the limit body 1071 of described Metallic rod 107 and the stopper slot 1081 of described handrail 108 of the connecting hole 1061 of described elastic component 106, described fixing inner panel 104, the precise positioning while having realized described movable armrest board rotation.Therefore, the present invention can simplify manufacture, the assembling operation of movable armrest board, makes user obtain preferably movable armrest board experience, increases the reliability of movable armrest board simultaneously.
Above a kind of adjustable armrest support provided by the present invention is described in detail, for one of ordinary skill in the art, according to the thought of the embodiment of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
