The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
The overall structure of present embodiment as shown in Figure 2, comprise rotary electric machine 1, slideway 13, car door 14, the roller 16 that is slidingly matched with slideway 13 inwalls, the hinged support arm 15 that is matched with between car door 14 belows and the car door frame, roller 16 is by linking arm 2 and the assembling of car door 14 tops, screw rod 7 one ends are connected with the output of rotary electric machine 1, screw rod 7 horizontal fixed are on the car door frame of car door 14 tops and be two sections integral structures that thread rotary orientation is opposite, symmetry be set in screw rod 7 external surfaces and with the slipping block 4 of its threaded engagement, be slidingly matched with slipping block 4 and with the fixing feed rod anti-rotation device of car door frame; Slipping block 4 is slidingly matched with linking arm 2.Slideway 13 is vertical with car door and symmetrical class " an eight " font slideway.Every slideway is formed by the slideway parallel with the car door upper side frame with its tangent circular arc slideway that is communicated with respectively in class " eight " the font slideway.
Anti-rotation device includes one and be arranged in parallel with screw rod 7 and feed rod 8 on the car door frame is fixed at two ends, slipping block 4 is slidingly matched with feed rod 8, slipping block 4 cooperates with screw rod 7 threads turn, the fixing assembling of nut on carrier bar 3 one ends and the slipping block 4, linking arm 2 is slidingly matched with the bar hole that carrier bar 3 other ends are offered.
Rotation direction is opposite in the screw rod 7 is arranged with travel switch 5,6 in abutting connection with the position, the other end of screw rod 7 is provided with brake 12.The other end of screw rod 7 also is provided with the striking plate 11 by steel wire 9 controls, and travel switch 10 is located at striking plate 11 tops.
The operating principle of present embodiment is:
Driving the slipping block that rotated by feed rod 8 carryings, limit 4 with rotary electric machine 1 by opposite two sections screw rods 7 of rotation direction and carrier bar 3 moves along linear reciprocation; then being connected in the linking arm 2 that can vertically move on the slipping block 4 is forced to along slideway 13 curve slidings through roller 16; just make the car door 14 that is connected on the linking arm 2 by slideway 13 curvilinear path slippages, thereby realize that the curve unlatching of car door 14 to car outside is affixed on closing of vehicle body with concordant.Close and after unlatching puts in place, send signal for rotary electric machine 1 by travel switch 5,6 at car door 14, rotary electric machine 1 outage stops operating; Brake 12 outages simultaneously, the brake(-holder) block in the brake 12 can not rotate screw rod 7, thereby plays the effect of braking car door 14.When needing manually to open and close car door 14, pulling steel wire 9, striking plate 11 move and touch travel switch 10 and makes rotary electric machine 1 outage, and brake(-holder) block is thrown off simultaneously, and screw rod 7 freely rotates, thereby can be with manual unlocking or closed door 14.Support arm 15 car door 14 close with the opening movement process in play the booster action of guiding, balance car door 14.
