Abstract
An electric jack for an automobile comprises a base, an upper support, an upper left connecting rod, an upper right connecting rod, a lower left connecting rod, a lower right connecting rod, a screw rod, a nut, a motor and a support. The upper end of the upper left connecting rod and the upper end of the upper right connecting rod are hinged to the upper support. The lower end of the lower left connecting rod and the lower end of the lower right connecting rod are hinged to the base. The lower end of the upper left connecting rod is hinged to the upper end of the lower left connecting rod. The lower end of the upper right connecting rod is hinged to the upper end of the lower right connecting rod. The motor is arranged at the hinge position of the upper left connecting rod and the lower left connecting rod. The motor is connected with one end of the screw rod. The nut is arranged at the other end of the screw rod. The nut is connected with one end of the support. The other end of the support is connected to the hinge position of the upper right connecting rod and the lower right connecting rod. The support and the nut are matched with the screw rod, so that the screw rod is short; the end portion of the screw rod cannot be exposed outside after the electric jack rises, as a result, the space occupied in the using process is small, and the risk that a maintenance man is injured due to a collision is lowered; the contact area between the nut and the screw rod does not change, and therefore power required by the electric jack for ascending and descending does not change.

In order further to realize the purpose of this utility model, can also be by the following technical solutions: described support be sleeve pipe, and the axis of sleeve pipe and the axis of screw mandrel are straight line, and the internal diameter of sleeve pipe is greater than the internal diameter of screw mandrel.Between described motor and leading screw, change speed gear box is set.Described motor connects two-direction switch, two-direction switch point of connection smoke device plug.Between described two-direction switch and cigarette lighter plug, by the wire socket connection, the communication port place of two-direction switch and wire arranges dust cap.Described pop-up top arranges adapter shaft, and bracket is set on adapter shaft, offers cross recess on bracket.Described bracket top arranges asperities.
The utility model has the advantage of: support and nut coordinate with screw mandrel, thereby the length of screw mandrel is shorter, and after jack hoists, the end of screw mandrel can not leaked externally, and the space that use procedure occupies is little, reduce the risk that the maintainer damages; Nut and screw mandrel area of contact are constant, and jack rising and the required power that descends are constant.The utility model also has advantages of compactness simple for structure, cheap for manufacturing cost and easy to use.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model; Fig. 2 is that the A of Fig. 1 is to looking the structure for amplifying schematic diagram.
Reference numeral: 1 motor 2 upper left connecting rod 3 pop-up 4 upper right connecting rod 5 nut 6 support 7 asperities 8 change speed gear box 9 dust cap 10 screw mandrel 11 lower-left connecting rod 12 base 13 bottom right connecting rod 14 two-direction switch 15 cigarette lighter plug 16 bracket 17 cross recess 18 adapter shafts.
The specific embodiment
Electric jack for automobile, as shown in the figure, comprise base 12, pop-up 3, upper left connecting rod 2, upper right connecting rod 4, lower-left connecting rod 11, bottom right connecting rod 13, screw mandrel 10, nut 5, motor 1 and support 6, the upper end of the upper end of upper left connecting rod 2 and upper right connecting rod 4 is hinged with pop-up 3 respectively, the lower end of the lower end of lower-left connecting rod 11 and bottom right connecting rod 13 is hinged respectively at base 12, the upper end of the lower end of upper left connecting rod 2 and lower-left connecting rod 11 is hinged, the upper end of the lower end of upper right connecting rod 4 and bottom right connecting rod 13 is hinged, upper left connecting rod 2 and lower-left connecting rod 11 hinged places arrange motor 1, motor 1 connects an end of leading screw 10.Between described motor 1 and leading screw 10, change speed gear box 8 is set, change speed gear box 8 is convenient to adjusting rotary speed.The other end of screw mandrel 10 arranges nut 5, an end of nut 5 connection brackets 6, and the other end of support 6 connects the hinged place of upper right connecting rod 4 and bottom right connecting rod 13.Support 6 and nut 5 coordinate with screw mandrel 10, thereby the length of screw mandrel 10 is shorter, and after jack hoists, the end of screw mandrel 10 can not leaked externally, and the space that use procedure occupies is little, reduce the risk that the maintainer damages; Nut 5 is constant with screw mandrel 10 area of contact, and jack rising and the required power that descends are constant.Described support 6 is sleeve pipe or strut bar, preferred sleeve pipe, and the axis of the axis of sleeve pipe and screw mandrel 10 is straight line, and the internal diameter of sleeve pipe is greater than the internal diameter of screw mandrel 10, and sleeve pipe can be protected screw mandrel 10, simultaneously, the easy to process and solid compactness of sleeve pipe.The biggest lifting capacity of the present utility model is 2 tons.
