Description
Technical field
The present invention relates to a kind of automobile miniature electric jack, be specially a kind of multistage ball-screw work-saving device, motor-driven and miniature electric jack with permanent magnet band-type brake of adopting, belong to mechanical equipment technical field.
Background technology
Jack is with car indispensability instrument, jack-up maintain part vehicle body at certain altitude when being usually used in auto repair or change tire.Existing it is commonly used in having of kart: rhombus hand-rail type jack, manually or hydraulic jack, rhombus hand-rail type jack realizes lifting by the rotation of leading screw, be easy to carry, easy to use and take up room little, this kind of jack normally only uses when needs re-type or repairing tyre, long-time idle it be easily caused leading screw and get rusty, make screw turns get up highly difficult；Hydraulic jack is heavier, takes dynamic and places all inconvenient, especially with time need to consume bigger muscle power.
The jacking mechanism of new patent " a kind of electric jack for vehicle " (CN03254400.6) is made up of the outer layer screw rod of spiral shell in the center bolt with outer spiral shell, middle screw rod with inside and outside spiral shell, band；Middle screw rod is enclosed within center bolt, and outer layer screw sleeve is in middle screw rod, and the inside and outside spiral shell between each screw rod engages each other；Motor drives center bolt to rotate by reducing gear, makes middle screw rod, outer layer screw rod jack-up.Its advantage is that volume is little, and driven by motor lifts；Its deficiency is: for being conducive to screw rod self-locking, the lead angle on each screw rod is less than the equivalent friction angle of each nut stem material, and so during motor jack-up, required rated power is bigger, especially because being not frequently used reason, when corrosion occurs in screw rod, motor starting moment is big, stall phenomenon even occurs.
Patent of invention " small size gasoline jack for vehicles " (CN201510902109.9) includes supporting seat, pedestal, and ball-screw and feed screw nut, motor, first to～fourth link, when motor output end ball-screw rotates, jack lifting is driven by linkage, it is disadvantageous in that: because of bar linkage structure reason, the material of 1 this kind of jack pair ball-screw and strength demand are very tight, and during work, ball-screw stress is fragile greatly；2 its volumes are relatively big, not readily portable and deposit；3 rising or falling speeds are slower；4 all do not record motor in this description of the invention and claims simultaneously is connected with nut seat, and therefore motor in operation will rotate around ball-screw, can not drive ball-screw.
Summary of the invention
The present invention seeks to overcome described in background technology not enough, a kind of automobile miniature electric jack of design, there is laborsaving and quick electric lifting, simple in construction, compact simultaneously, it is simple to the advantage such as carry and deposit.
