The specific embodiment
By Fig. 1, known, a kind of electricity powered car door reduction of heat noise reduction acceleration system, comprise door device 1 and Men Tou mechanism 7, door device 1 is comprised of two of left and right door leaf and shift fork 1-2, Men Tou mechanism 7 is located at the top of door leaf, and driving mechanism 2, transmission device 3, guiding mechanism 4, locking device 5 and door control unit (DCU) 6 are housed in Men Tou mechanism 7.Driving mechanism 2 is comprised of motor and shaft coupling; Transmission device 3 is comprised of combined threaded rod, nut and three supporting bases; Described door control unit (DCU) 6 sends instruction, motor drives diameter progressive screw rotation, reducing nut drives shift fork 1-2, door leaf to do rectilinear motion along screw axis direction, and path nut-screw pair screws that to realize car door rapidly opened and closed, and large footpath nut-screw pair screws realizes car door fast self-locking.
By Fig. 2, being known, is the left view of Fig. 1.The upper lateral part of door leaf is connected with shift fork 1-2, and shift fork 1-2 is link rod structure, by the loaded axle 8 being arranged in Men Tou mechanism 7, is connected with reducing combination nut 3-1.
By Fig. 3, being known, is the structural representation of transmission device.Transmission device 3 is reducing combined threaded rod nut screw pairs, comprise reducing combination nut 3-1 and reducing combined threaded rod 3-2, reducing combined threaded rod 3-2 is supported in Men Tou mechanism 7 by left and right supporting base 3-3 and middle supporting base 3-4, reducing combination nut 3-1 and reducing combined threaded rod 3-2, be divided into right (dextrorotation) two sections in a left side (left-handed) take middle supporting as boundary; Two ends are large helical pitch minor diameter screw pair, implement door device 1 close leading portion, open back segment, reducing combination nut 3-1 and reducing combined threaded rod 3-2 screw, screw diameter is Φ 16mm, in low friction, realizes fast moving; At middle part near middle supporting base 3-4, left and right is respectively provided with the little lift angle screw pair of major diameter that a segment length is less, and screw diameter is Φ 104mm, large footpath little lift angle part reducing combination nut 3-1,3-2 screws with reducing combined threaded rod, implement door device 1 close latter end, open leading portion.Described reducing combination nut 3-1 adopts model engineering plastic to make.Left and right two parts of reducing combined threaded rod 3-2, are provided with the diameter of thread and are bis-sections of Φ 16mm and Φ 104mm respectively, its large footpath section Φ 104mm, lead angle λ=5.81 °, equivalent friction angle arc tan fv=5.91 °.
It is rapidly opened and closed that described locking device 5 and transmission device 3 the two unification: path Tr16*32 (p8) part realize car door, large footpath Tr104*32 (p8) part, and length only has 32mm, realizes the locking functions of car door.
Embodiment 1:
Fig. 4 is the locking device structure chart of embodiment 1.A kind of form that locking and transmission are two-in-one, reducing combination nut 3-1 is combined by path nut 3-11 and large footpath nut 3-12.Path nut 3-11 and reducing combined threaded rod path part 3-21 screw that to realize car door rapidly opened and closed, adopt the model engineering plastic that friction factor (f=0.11) is less to make.Large footpath nut 3-12 and reducing combined threaded rod large diameter portion 3-22 screw, and meet mechanical self-latching condition.Large footpath nut 3-12 adopts the model engineering plastic that friction factor (f=0.45) is larger to make.During normal work, reducing combined threaded rod nut minor diameter part divides relative motion, drives door leaf switch, and this section friction factor is little, frictional heat is few, noise is low, is suitable for rapid movement; Door leaf cuts out rear (while being about to cut out), and large diameter portion bolt and nut screws, and its lead angle (λ=24.84 °) is less than equivalent friction angle (arc tan fv=24.98 °), meets mechanical self-latching condition.Therefore after closing of the door, when without external torsional interaction, car door cannot be opened, and realizes self-locking.Relatively, large path difference is less, and structure is more reasonable, and manufacturability is more excellent.
