Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in accompanying drawing one, the utility model discloses a kind of mechanical device of automobile tail gate strut, comprise ball head connecting piece 1, lower ball head connecting piece 17, motor box 6 and screw mandrel 11, be provided with driver train in described motor box 6, upper ball head connecting piece 1 is locked at motor box 6 upper end by screw 2; Also comprise from outer toward the interior spring overcoat 13, spring inner sleeve 9 and the ut socket 12 that are set with successively, ut socket 12 outer wall is set with spring 14, and this spring 14 is arranged in spring inner sleeve 9; Screw mandrel 11 is contained in ut socket 12, and this screw mandrel 11 upper end upwards extends and bearing 10 is housed, and this screw mandrel 11 upper end is connected with the driver train in motor box 6 by coupler 8, and this screw mandrel 11 lower end is to downward-extension and guides 15 is housed; The lower end attaching of ut socket 12 has base 16, and lower ball head connecting piece 17 is arranged on this base 16.
Described driver train comprises the Direct Current Motor 5 and retarder 7 that are connected, and this retarder 7 is connected with screw mandrel 11 by coupler 8.The transmission shaft of Direct Current Motor 5 is provided with four pole magnetic sheets 3, the terminals of this Direct Current Motor 5 are provided with wiring board 4, this wiring board 4 is equipped with hall sensing element, can accurate feedback motor rotating cycle by hall principle, to realize stretching strut, the accurate control object of indention journey.
For the ease of installing, ut socket bottom outer wall is provided with screw thread, locks between base and ut socket in the screw thread mode of spinning.To install in the screw thread mode of spinning between ball head connecting piece and base down.Install in the screw thread mode of spinning between upper ball head connecting piece and screw.
In the process of concrete assembling, upper ball head connecting piece 1 is connected with screw 2 and is locked at motor box 6 upper end; Screw mandrel 11 installs guides 15, then screw in ut socket 12; Again together through behind the hole of spring inner sleeve 9, load onto bearing 10; With coupler 8, the axle of the output shaft of drop-gear box 7 with screw mandrel 11 is connected again; Direct Current Motor 5, drop-gear box 7, coupler 8, bearing 10 are fixed in motor box 6; Motor box 6 is inserted in after closing shell in spring inner sleeve 9 again; Spring 14 is enclosed within outside ut socket 12, loads in spring inner sleeve 9, then is inserted in spring overcoat 13 by spring 14 other end; On ut socket 12 outside thread, the assembly parts of locking base 16 and lower ball head connecting piece 17, can link together ut socket 12, base 16, spring overcoat 13, lower ball head connecting piece 17.
