Embodiment
Below in conjunction with accompanying drawing the turning device that is used for vehicle-carrying display screen of the present utility model is described in further detail.As shown in Figure 1 to Figure 3, in the present embodiment, the turning device that is used for vehicle-carrying display screen of the present utility model comprises motor 1, worm screw 2, gear set 3, tooth bar 4, panel 5, display screen 6 and housing 7.Described motor 1, worm screw 2, gear set 3, tooth bar 4, panel 5 can be installed on the described housing 7, can certainly be directly installed on the car body.And described tooth bar 4 passes described housing 7; Described panel 5 then can be used as a sidewall of described housing 7, and intersects vertical setting substantially with described tooth bar 4.
Described worm screw 2 is installed in the rotating shaft of described motor 1 output terminal, and can be along with described rotating shaft rotation.Described gear set 3 comprises the worm gear 31 with described worm screw 2 engagements, with the spiral gear 32 of described worm gear 31 one coaxial rotation, with the big small stair spiral gear of described spiral gear 32 engagements, with the thickening spiral gear 35 of described big small stair spiral gear engagement.Described tooth bar 4 is a helical rack, described thickening spiral gear 35 and described tooth bar 4 engaged transmission; Certainly, described tooth bar 4 can be spur rack, and the spur gear that corresponding thickening spiral gear 35 is designed to thicken, the part that the corresponding helical gear and described thickening spur gear of described big small stair is meshed is that straight-tooth gets final product.In order to make the transmission of power more reliable and more stable, described big small stair spiral gear comprises the first small stair spiral gear 33 and the second largest small stair spiral gear 34 of two transmissions that are meshed; Certainly, a plurality of big small stair spiral gears or a big small stair spiral gear can be set according to actual needs.The gear wheel of described first small stair spiral gear 33 and described spiral gear 32 engaged transmission are rotated thereby drive described first small stair spiral gear 33; The transmission that is meshed with the gear wheel of described second largest small stair spiral gear 34 of the pinion wheel of described then first small stair spiral gear 33, rotate the transmission that then is meshed of the pinion wheel of described second largest small stair spiral gear 34 with described thickening spiral gear 35 thereby drive described second largest small stair spiral gear 34.
One end of described display screen 6 directly is fixedly mounted on the described tooth bar 4, and does tangential movement by described tooth bar 4 drives; As shown in Figure 5, described display screen 6 also can be connected with described tooth bar 4 by a plate 10.Described web joint 6 is connected and fixed with tooth bar 4, and does tangential movement by described tooth bar 4 drives.The other end of described display screen 6 then is connected with described tooth bar 4 and intersects substantially on the vertically disposed panel 5.And described display screen 6 and described panel 5 are provided with the carriage that makes that the other end of described display screen 6 can slide on described panel 5.Described carriage comprise be located on described display screen 6 and the end that described panel 5 contacts, and the pulley 8 that can on described panel 5, slide up and down.In order to make described pulley 8 better to slide, described carriage also comprises and is arranged on guide rail 9 on the described panel 5, that slide for described pulley 8 within it.
When needs overturn described display screen 6, at first start described motor 1, make the worm screw 2 that is connected with described motor 1 rotate, thereby drive and worm gear 31 rotations of described worm screw 2 engaged transmission; Because described spiral gear 32 is that one is coaxial with described worm gear 31, rotate thereby drive described spiral gear 32; Described spiral gear 32 and the first small stair spiral gear 33 of drive drive described second largest small stair spiral gear 34 by described first small stair spiral gear 33 again and rotate; Described then second largest small stair spiral gear 34 drives described thickening spiral gear 35 and rotates, and described thickening spiral gear 35 drives described tooth bar 4 again and does tangential movement; Because an end of described display screen 6 is fixed on the described tooth bar 4, thereby described tooth bar 4 drives described display screen 6 and moves horizontally, the pulley 8 that drives the other end of described display screen 6 simultaneously slides on described panel 5, makes flip-flop movement thereby drive described display screen 6.By gear set 3 dynamical stability of described motor 1 is slowed down and to transmit, and the two ends of display screen 6 all do stable action, thereby make that the rotation of display screen 6 is more steadily reliable; Its structure is also compact.
