[detailed description of the invention]
Below in conjunction with specification drawings and specific embodiments, the present invention is further described.
The embodiment of the present invention 1 and embodiment 2 comprise motor, Motorized lift device and anti-dazzle device.
Motor described in embodiment 1 is positive and negative motor, and Motorized lift device adopts bamboo joint type up-down mode, for the spiral synchronization lifting of three joints.
As shown in Figure 1, 2, described Motorized lift device comprises one-level initiatively leading screw 1 and one-level thick stick body 2, secondary lever bracket dish 6, secondary initiatively leading screw 3 and secondary thick stick body 4, and three grades of thick stick bodies 5.One-level thick stick body 2, secondary thick stick body 4 and three grades of thick stick bodies 5 form the sleeve pipe be nested, and three grades of thick stick bodies 5 of sleeve pipe innermost layer are push pipe.Described one-level initiatively leading screw 1 is arranged in one-level thick stick body 2, one-level thick stick body 2 is arranged on base 7, the polished rod part of one-level active leading screw 1 is connected with base 7 by bearing, the power intake 8 of one-level active leading screw 1 is exposed to outside base 7, link with motor output end, the type of drive between described power intake 8 and motor output end can be gear transmission (not showing motor in figure).Described secondary lever bracket dish 6 is with mesopore, and cross section is ring-type, is positioned at one-level thick stick body 2 inner, and secondary lever bracket dish 6 inner ring inner thread and one-level initiatively leading screw 1 outer wall thread are corresponding, and screw-casing is contained on one-level active leading screw 1.On secondary active leading screw 3 outer wall, cover has the screw thread matched with three grades of thick stick body 5 inwalls.
As shown in Figure 3, described secondary thick stick body 4 is fixedly mounted on secondary lever bracket dish 6.Secondary initiatively has a circle bead 9 in leading screw 3 upper end, has an annular arrangement briquetting 10 that this bead 9 is pressed in secondary lever bracket dish 6 lower surface.Annular arrangement briquetting 10 can be fixed on secondary lever bracket dish 6 by spiral nail.
As shown in Figure 4, described secondary lever bracket dish 6 outer wall has corresponding concaveconvex structure 11 with one-level thick stick body 2 inwall, plays position-limiting action, and one-level thick stick body 2, secondary lever bracket dish 6, secondary thick stick body 4 can not be rotated.
Described secondary initiatively leading screw 3 is hollow, and one-level active leading screw 1 is in secondary initiatively leading screw 3 cavity.One-level active leading screw 1 outer wall and secondary initiatively leading screw 3 inwall have by cutting the tangent plane 12 forming correspondence, and to ensure one-level active leading screw 1 when rotated, initiatively leading screw 3 is inner both can to have passed in and out secondary smoothly, and secondary active leading screw 3 can be driven again to rotate simultaneously.The structure of this tangent plane can be as shown in Figure 5.
As shown in Figure 6, three grades of thick stick body 5 outer walls have corresponding concaveconvex structure 13 with secondary thick stick body 4 inwall, play position-limiting action, and secondary thick stick body 4 and three grades of thick stick bodies 5 can not be rotated.
Described anti-dazzle device 14 can be a monoblock, also can make to fold.Three grades of thick stick body 5 ends are connected with anti-dazzle device 14 (be blocked plate 14 in figure to block, do not show) by a connecting device, and described connecting device comprises universal ball connector.
Described motor and Motorized lift device are arranged in housing, and there is opening the below of housing, and Motorized lift device is stretched out by this opening.If with the vehicle of operator's compartment, housing can be arranged on the former sun shield place of driver's side, and adopts vertical or parallel etc. from front windshield different hang according to different automobile types.For the vehicle not having operator's compartment, as motor bike, battery-driven car, housing can be arranged on the helmet, and possess detachable function to be convenient for people to use.
The motor switch of the present embodiment 1 is teleswitch, and teleswitch can be placed on bearing circle, and power supply can utilize automobile power source or other power supplys.When pressing raise/lower actuator, motor output gear drives power intake 8 gear be arranged on one-level active leading screw 1 to rotate, make one-level initiatively leading screw 1 generation rotation, secondary lever bracket dish 6 produces longitudinal travel along one-level active leading screw 1, drives secondary thick stick body 4 to rise/land; While one-level active leading screw 1 rotates, because one-level active leading screw 1 outer wall and secondary active leading screw 3 inwall have the effect by cutting tangent plane 12 corresponding to formation, drive secondary active leading screw 3 produces rotation, thus realizes the rise/landing of three grades of thick stick bodies 5.And the final anti-dazzle device 14 that drives is elevated, and then anti-dazzle device 14 is made to rest on the object suitably highly reaching change strong light dazzling prevention as required.
Embodiment 2 adopts step by step up-down mode section by section.As shown in Figure 7, embodiment 2 comprises housing 15, motor 16, Motorized lift device and anti-dazzle device 14.Opening is had below described housing 15.
Described Motorized lift device comprises the sleeve pipe that more piece is nested, and is arranged on the steel tie rod 17 with hole clipping, disc spring 18 and the power input gear 19 in housing 15.The latch of power input gear 19 engages with the hole clipping on steel tie rod 17.The object of disc spring 18 is that tension steel tie rod 17 prevents its free-extension.Described more piece sleeve pipe is outermost is bottom tube 20, bottom tube 20 is fixedly mounted on housing 15 lower opening place, described sleeve pipe innermost layer be push pipe 21, push pipe 21 end is fixed with a connecting device, connecting device is connected with anti-dazzle device 14 (to be blocked plate 14 to block in figure, do not show), described connecting device comprises universal ball connector.Described motor 16 mouth and power input gear 19 link, and this kind of interlock can have been connected by gear.The connecting device of described steel tie rod 17 one end connecting jacking pipe 21 end, the other end connects disc spring 18, and the other end of disc spring 18 is fixed in housing 15.
Limited location block 22 in described housing 15, its object is to guide steel tie rod 17 can only carry out fore and aft motion along the direction of regulation.Limiting stopper 22 structure can be also guiding indent, and steel tie rod 17 is placed in guiding indent, and guiding indent can be designed to certain radian, thus better increasing controls the occlusion of steel tie rod 17.
Described anti-dazzle device 14 can be a monoblock, also can make the flap that can fold.
The switch of the motor 16 of the present embodiment 2 is teleswitch, teleswitch can be placed on bearing circle, when pressing raise/lower actuator, by motor 16 transmission to power input gear 19, power input gear 19 drives steel tie rod 17 extension/retraction, more piece sleeve pipe launches section by section step by step/regains, and anti-dazzle device 14 declines/be elevated to correct position.
In embodiment 3 except the structure in embodiment 1, also comprise the photoswitch be connected with motor circuit, described photoswitch comprises the connected external sense electronics shaven head of circuit, signal conversion circuit, amplifying circuit and PLC.The optical signal that described external sense electronics shaven head collects is converted to electric signal through signal conversion circuit, and after the amplifier in amplifying circuit amplifies, be transferred to PLC set in circuit, PLC controls motor forward or reverse.Under high light, the PLC of photoswitch makes motor rotate forward, and sun shield 14 is fallen; Light is lower than setting threshold, and PLC makes motor reversal, and sun shield 14 rises.
In embodiment 4 except the structure in embodiment 2, also comprise the photoswitch that motor circuit is connected, described photoswitch structure and the structure in embodiment 3, function are identical.
It should be noted that; particular of the present invention is to invention has been detailed description; for a person skilled in the art, the various apparent change carried out it when not deviating from the spirit and scope of the present invention is all within protection scope of the present invention.
