The mechanical device has the advantages that the mechanical device is driven by the motor, so that the automatic jack is more labor-saving to operate, and the motor and the speed reducer are installed in the inner space of the hoisting arm, so that the volume of the jack can be saved. The jack can be widely used for drivers.

Description

A kind of electric automotive jack

Technical field

The utility model relates to a kind of mechanical device, specifically is meant the automatic jack of a kind of vehicle by motor action.

Technical background

At present a lot of automobile screw mandrel formula jacks are accomplished the up-down of jack through the rocking arm of artificial both hands rotary screw rod, waste time and energy.Some car jack is through motor-driven, but after motor was installed, volume was bigger, and motor is also heavier, has increased the load of automobile.Therefore, the design is to provide a kind of light, motorcar electric jack that volume is less.

The utility model content

The utility model is to deficiency of the prior art, proposed a kind of handled easily, light, motorcar electric jack that volume is less.

The utility model is achieved through following technical proposals:

A kind of electric automotive jack comprises base, lifts arm, it is characterized in that: the motor fabricated section is installed in the inner space of lifting arm, and motor and retarder are formed one and be installed in together in the motor fabricated section; When jack was packed up, the motor fabricated section is installed in lifted the grooved inside that arm surrounded; The shaft of motor reducer is connected through holding screw with screw mandrel, is rotated by motor rotating band movable wire bar, and then drives lifting arm, realizes the lifting action of upper bracket.

As preferably, the motor of above-mentioned a kind of motorcar electric jack is controlled by peripheral control unit, and the illumination of LED lamp is arranged on the controller, and the LED lamp places the LED lampshade.

As preferably; Screw mandrel one end is connected through holding screw with the shaft of motor reducer in above-mentioned a kind of motorcar electric jack, and screw mandrel contacts with thrust ball bearing simultaneously, and its axial force is born by thrust ball bearing; The other end of screw mandrel is connected with nut, constitutes screw pair.

Beneficial effect: the design uses motor-driven, makes that the operation of car jack is more laborsaving, through motor and retarder are installed in the inner space of lifting arm, has saved the volume of jack.

The specific embodiment

Below in conjunction with accompanying drawing, the enforcement of the utility model is specified:

Embodiment 1

As shown in Figure 1; The technical scheme that present embodiment adopts is: a kind of elec. vehicle jack, and comprise base 5, lift arm, motor and retarder 9 and be installed in motor fabricated section 10 the insides, the shaft of motor reducer and screw mandrel 6 are connected through holding screw; Rotation through motor and retarder 9; Drive the rotation of screw mandrel 6, lift arm 1,2,3,4 motions, realize the lifting action of upper bracket 8 thereby drive.Motor movement can be controlled the motion of motor and retarder 9 through its rising button 13 and decline button 14 easily through controller 12 controls; Also have LED lamp 18 to be used for illumination on the controller 12.Said motor fabricated section 10 is installed in jack and lifts in the inner space of arm 1,2,3,4, and motor and retarder 9 are installed in the motor fabricated section 10 together, and when jack was packed up, motor fabricated section 10 was in grooved is lifted the grooved space of arm; Said motor is by vehicle power supply, and jack has external controller 12, and rising button 13 and decline button 14 are arranged on the controller 12, also has LED lamp 18 to be used for illumination on the controller 12.LED lamp 18 places LED lampshade 17, and LED lampshade 17 can make illumination zone wider, and light is more concentrated.

Embodiment 2

As shown in Figure 1, this jack mainly comprises lifts arm 1,2,3,4, base 5, screw mandrel 6; Nut 7, upper bracket 8, motor and retarder 9, motor fabricated section 10; Power lead 11, controller 12, rising button 13, decline button 14; Automobile cigarette lighter 15, control circuit board 16, LED lampshade 17 and LED lamp 18.Motor and retarder 9 are installed in the motor fabricated section 10, the groove width that the width of motor fabricated section 10 is lifted arm less than grooved, and when jack was packed up, motor fabricated section 10 was in grooved is lifted the grooved space of arm.LED lampshade 17 can make the illumination zone of LED lamp 18 wider, and light is more concentrated.Screw mandrel 6 one ends are connected through holding screw with the shaft of motor reducer, and screw mandrel 6 contacts with thrust ball bearing 19 simultaneously, and its axial force is born by thrust ball bearing 19, and the other end of screw mandrel is connected with nut 7, constitute screw pair.

During concrete operations, earlier automobile cigarette lighter 15 and automobile power source are connected, pressed rising button 13, motor 9 is just changeing, and drives screw mandrel 6 forward rotation, lifts arm 1,2,3,4 motions, and the upper bracket 8 of jack rises, and has realized the action of top automobile.Otherwise, press decline button 14, the motor counter-rotating, the upper bracket 8 of jack is accomplished down maneuver.
