The specific embodiment
As Figure 1-3, a kind of vehicle Multifunctional electric jack, it comprises motor 1, air pump 2, oil pump 4, oil cylinder 5 and fuel tank 7, and air pump 2 and oil pump 3 are arranged on the front and back mouth of motor 1, and described air pump 2 bodies connect with the rear mouth of motor 1 by power-transfer clutch 21; Be meshed by the mouth of valve body 3 with motor 1 at described oil pump 2, described valve body 3 and oil cylinder 5 have common base 6; Be provided with the asphalt channel that is communicated with oil cylinder 5, oil pump 4 and fuel tank in the inside of described valve body 3 and base 6; Described asphalt channel comprises oil inlet passage 31, drainback passage 32, control oil duct 33 and the non-return oil duct 34 that is arranged in the valve body, and oil inlet passage 31 and drainback passage 32 are communicated with described oil inlet passage 31 with fuel tank and communicate with the import 41 of oil pump 4; Be provided with piston 35 at described control oil logical 33, piston 35 is controlled the conducting of drainback passages 32 and control oil duct 33 and is closed, piston all arranges piston rod in both sides about in the of 35, upper piston rod 36 passes the surface of valve body 3, lower piston rod 37 extends to non-return oil duct 34, be provided with boiler check valve 38 at non-return oil duct 34 entrance points, non-return oil duct 34 is communicated with oil cylinder 5 by the asphalt channel of base 6 inside; The outlet 42 of described oil pump 4 is communicated with control oil duct 33, is provided with check valve at outlet 42 places of oil pump 4.
Working process of the present utility model:
As shown in Figure 4, the top working process is such on the jack: motor 1 forward drives the gear rotation of oil pump 4, this moment, air pump was because disengaging of clutch and motor are isolated can not work, oil pump is just being transferred from a team to another and is being caused drainback passage 32 internal oil pressure to be lower than the oil pressure of control oil duct 33 inside simultaneously, this moment, piston can will be controlled oil duct 33 and drainback passage 32 isolation by automatic-ascending, controlling simultaneously the boiler check valve 38 that the interior oil pressure of oil duct 33 continue to rise non-return oil duct 34 entrance points backs down, and the asphalt channel of hydraulic oil in base entered in the oil cylinder, thereby push up on the realization oil cylinder, thereby the jack of realizing rises; Owing to be provided with the check valve that outlet 42 places of boiler check valve 38 and oil pump 4 arrange at the time entrance point of non-return oil duct 34, when quitting work, plays by oil pump the effect of double non-return, guarantee the reliability of jack work.
As shown in Figure 5, jack decline working process is such: motor 2 counter-rotatings, so that drainback passage 32 interior oil pressure rise, when drainback passage 32 interior oil pressure rise to greater than the oil pressure in the control oil duct 33, can automatically back down piston 35,35 times movements of piston are so that lower piston rod 37 backs down boiler check valve 38, then stop operation of oil pump, oil cylinder 5 is pressed to return flow line 32 with the hydraulic oil of oil cylinder 5 from control oil duct 33, until jack resets under the effect of pressure of vehicle at this moment; Can drive air-pump work during motor reversal, realize the function of inflation pump.
The off-load of the utility model oil cylinder can also make lower piston rod remove to back down the boiler check valve 38 of non-return oil duct 34 by pressing upper piston rod, and utilizes pressure of vehicle to realize the automatic back flow of hydraulic oil in the oil cylinder,
The utility model also is provided with adjusting screw(rod) 51 at described oil cylinder 5 tops in addition, adjusting screw(rod) 51 is screwed in the screw at oil cylinder 5 tops, can regulate the height that pushes up on the oil cylinder by rotation adjusting screw(rod) 51, it mainly is different for the height on different automobile types chassis that adjusting screw(rod) 51 is set at oil cylinder 5 tops, for some chassis cross-country car, present jack rises to vertex still can't be with the complete jack-up of vehicle, and adjusting screw(rod) 51 is set at the oil cylinder top, during for the higher cross-country car in chassis, can rotate up first adjusting screw(rod) 51, so just be equivalent to have improved the height on the upper top of jack, thereby satisfy the demand of the higher vehicle in chassis; And for the vehicle of the chassis end of than, adjusting screw(rod) 51 is regulated nadir, and at this moment jack of the present utility model is identical with common jack.
The utility model connects motor and oil pump by valve body, valve body is the control cock of oil circuit, it is again the butt flange that connects oil pump and motor, oil pump has adopted the small and exquisite gear type pump of volume, so that the utility model structure is more simple compact with respect to the structure of existing motor-driven jack, volume is smaller and more exquisite, moves more reliable and more stable.
