When the handrail lifting device works, the handrail control module 600 controls the screw rod driving motor assembly 200 to act, the screw rod driving motor assembly 200 drives the handrail function assembly 500 to turn and unfold through the handrail turning motion assembly 400, and then drives the handrail function assembly 500 in the unfolded state to lift through the handrail lifting motion assembly 300.
The electric two-way central armrest structure of the invention has the following driving force conversion path in each stage section:
referring to fig. 13, the electric two-way central handrail structure of the present invention drives the lead screw slider seat 230 to drive the handrail lifting assembly 300 and the handrail turning assembly 400 through the lead screw motor 210 to complete the electric folding and lifting functions of the handrail.
Referring to fig. 14 and 15, in the initial position, the armrest is in the lowermost, fully stowed position. The leg G of the armrest lifting/lowering assembly 300 and the fixed bracket assembly 100 contact the stop point O due to the gravity, and the sliding shaft 430 and the armrest lifting/lowering assembly 300 contact the stop point P.
Referring to fig. 16-18, the armrest is in the deployed stage. The lead screw motor 210 drives the lead screw slider seat 230 to move upwards through the rotation of the lead screw 220. The lead screw slider holder 230 drives the sliding rotation shaft 430 to move along the left and right armrest turning guide grooves 311a and 311b of the elevating bracket plate 310 and the left and right guide grooves 121a and 121b of the fixed base plate 110. The left and right upper hinge brackets 440a, 440b hinged to the sliding rotation shaft 430 are moved in synchronization with the sliding rotation shaft 430.
Referring to fig. 19 and 20, the armrest is in the deployed stage. The left and right upper hinge brackets 440a, 440b are connected to the lead screw slider holder 230 through the sliding rotation shaft 430, and can rotate around the sliding rotation shaft 430. The left and right upper hinge brackets 440a, 440b are connected to the left and right lower hinge brackets 450a, 450b by step locking posts 451a, 451b, the connection point being a movable end point a. The other ends of the left and right lower hinge brackets 450a, 450B are connected to the fixed shaft 420 at a fixed end point B. Therefore, the left and right upper hinge brackets 440a and 440B, the left and right lower hinge brackets 450a and 450B, the sliding shaft 430, the movable end point A and the fixed end point B form a crank-slider mechanism. The upward movement of the sliding shaft 430 drives the left and right upper hinge brackets 440a, 440B to move synchronously, the left and right upper hinge brackets 440a, 440B drive the left and right lower hinge brackets 450a, 450B to rotate around the fixed end point B through the movable end point a, and the movable end point a also rotates along with the left and right lower hinge brackets 450a, 450B.
Referring to fig. 21-23, the armrest is in the deployed stage. The left and right lower hinge brackets 450a and 450b are fixedly connected to the fixed shaft 420. The fixing shaft 420 is also fixedly connected with the handrail framework 410 through a limiting insert 415 and a fixing screw 414. The left and right lower hinge brackets 450a and 450b are fixed relative to the handle frame 410. The fixed shaft 420 rotates around the fixed end point B, and the handrail framework 410 is driven by the fixed end point B and the limiting insert 415 to rotate around the fixed end point B, so that the whole handrail is turned over and opened.
Referring to fig. 24 and 25, the armrest is in the fully extended position. When the lead screw motor 210 drives the lead screw slider seat 230 to move upwards and the handrail framework 410 and the handrail lifting motion assembly 300 contact the blocking point C, the turning motion reaches the limit position, and the handrail is completely unfolded. In this position, the stop point C is in rigid contact, the external load on the armrest frame 410 is borne by the armrest lifting movement assembly 300 through the stop point C, and the motor has no load. When the lead screw motor 210 drives the lead screw slider seat 230 and other related parts to continue moving upwards, the handrail enters into the handrail lifting stroke.
Referring to fig. 26 and 27, during the armrest lifting stroke, the armrest lifting/lowering movement assembly 300 is movably connected to the fixed bracket assembly 100 via the lifting/lowering guide block 320 and the support leg G. The lifting guide block 320 can guide the armrest lifting moving assembly 300 to move along the elongated guide slot 111 of the fixed bracket assembly 100 relative to the fixed bracket assembly 100. Through this connection, the Y-direction movement between the armrest lifting/lowering movement assembly 300 and the fixed bracket assembly 100 can be restrained. The leg G can move along the left and right guide grooves 121a and 121b of the fixed bracket assembly 100. The load on the arm-rest lifting motion assembly 300 is mainly borne by the legs G.
Referring to fig. 28, when the handrail is in the lifting stroke, when the lead screw motor 210 drives the lead screw slider seat 230 to move upwards continuously through the stroke node, the sliding rotating shaft 430 contacts with the handrail lifting movement assembly 300 at the stop point E. The sliding shaft 430 drives the armrest lifting/lowering movement assembly 300 to move upward along the fixed bracket assembly 100 relatively through the contact of the position. During this travel, the inside of the armrest turning motion assembly 400 remains relatively stationary, completing the overall raising of the armrest.
Referring to fig. 29 and 30, the armrest is in the fully raised position. When the screw rod sliding block seat 230 drives the sliding rotating shaft 430 to move until the sliding rotating shaft 430 contacts the fixed support assembly 100 at the stop point D, the motor is locked, the system reaches the movement limit position, and the armrest integrally reaches the highest lifting position.
