Description
The present invention relates to the device that a kind of electronic jack combines with electric air pump, particularly a kind ofly not only can make jack but also the device of making air pump is arranged.
The device of existing jack and air pump combination is the piston reciprocates that drives air pump and oil hydraulic cylinder with electrical motor by eccentric stiffener simultaneously, oil hydraulic cylinder and air pump are worked simultaneously, play the effect of while pump gas and jack stand weight, the device that combines with air pump as U.S. Pat 4746097 disclosed the sort of jacks, cylinder and oil cylinder coaxial arrangement in this device, air pump plunger is coaxial with fuel feed pump plunger, so pump gas and jack-up weight are effect simultaneously.Yet described device in use often need not require pump gas in the jack-up weight, and for example motor tire is damaged and when needing changing of tire, generally be first jack-up vehicle body changing of tire again, pump gas again behind the retread a tyre.This described existing apparatus must be that jack-up weight and pump gas carry out simultaneously, and this not only expends unnecessary energy but also the wearing and tearing of aggravation part also require the power of drive motor big simultaneously, uses also inconvenient.
Therefore, the objective of the invention is to propose the device (being the electric air pump jack) that a kind of jack combines with air pump, this device can make pump gas and jack-up weight carry out respectively, and operation is also very convenient.
The electric air pump jack that the present invention proposes, this jack comprises dc drive motor, source switch, eccentric drive mechanism, and jack assembly and air pump assembly, it is characterized in that: wherein also comprise free-wheel clutch, described source switch is the switch of the changed positive and negative electrode input end of two-phase, there is free-wheel clutch at the output shaft two ends of described dc drive motor attaching respectively, and this free-wheel clutch joins with the part that is driven of air pump assembly and jack assembly respectively by eccentric drive mechanism; Described free-wheel clutch has cup-shaped driven member, and the closed side of this cup-shaped driven member has the transmission gear that is meshed with the eccentric drive mechanism respective gears, and the center has through hole; Driving link is a disc, and the one side has boss, also has central through hole; Friction component is by " ┌ " shape part, " U " shape part and support spring are formed, " ┌ " shape part one end is hook-shaped, the curved wedge-like of the other end, the outside at its place of curving has an arc, " U " shape part one end has with described " ┌ " shape part and is the crotch that a hook-shaped end matches, vertical its in-plane of its other end is extended with a pin, this pin is inserted in the pin-and-hole on the disc-shaped part of disc driving link, have an arc convex on the external arc of " U " shape part, two support arms of support spring are supporting the arc wedge-like end of " ┌ " shape part and the end with pin of " U " shape part respectively; The dc drive motor axle passes the driving link centre hole, support spring center and driven member centre hole, this motor reel termination has collar, the driving link boss has screw, one screw is solidly connected driving link and electrical motor pivot pin, and driving link disk excircle cooperates rotationally with the cup-shaped inner periphery of driven member.
Described jack can be oil jack, also can be screw type mechanical type jack.
The electric air pump jack that the present invention proposes uses very convenient, because the dc drive motor two ends have been hinged with free-wheel clutch respectively, as long as switch bi-directional power switch, change the rotation direction of DC motor, can drive jack or air pump, not only can save energy consumption but also can reduce the wearing and tearing of unnecessary part, and noise is little, running steadily.
Below in conjunction with accompanying drawing embodiments of the invention are described further.
Fig. 1 is the general illustration of the embodiment of the electric air pump jack of the present invention's proposition;
The scheme drawing of the free-wheel clutch that Fig. 2 proposes for the present invention has only represented among the figure that friction component is installed in the signal situation on the driving link, as can be seen from Figure " U " shape part be by the pin on it with the driving link bonded assembly; Fig. 3 shows scheme drawing for the cuing open of free-wheel clutch that the present invention proposes, and its profile position is equivalent to the I-zero-I among Fig. 2.
Ask for an interview Fig. 1, this figure is the general arrangement of embodiments of the invention, and the source switch of dc drive motor 12 is bidirectional switch 11, and this bidirectional switch 11 can change the input polarity of power supply, thereby changes the rotation direction of DC motor 12.There is a free-wheel clutch 13 at the two ends of the output shaft of this electrical motor 12 attaching respectively, the driving link of this free-wheel clutch 13 is affixed with the output shaft two ends of electrical motor 12 respectively, by transmission gear 14 and corresponding eccentric drive mechanism, can drive air pump 16 or jack 15 respectively.
Described source switch 11 is the switch of the changed positive and negative electrode input end of two-phase, there is free-wheel clutch at the output shaft two ends of described dc drive motor 12 attaching respectively, this free-wheel clutch joins with the part that is driven of air pump assembly 16 and jack assembly 15 respectively by eccentric drive mechanism, ask for an interview Fig. 2 and Fig. 3, the figure shows the structure and the assembled condition of free-wheel clutch 13.
Described free-wheel clutch 13 has cup-shaped driven member 1, and the closed side of this cup-shaped driven member 1 has the transmission gear 7 that is meshed with eccentric drive mechanism respective gears 14, and driven member 1 has central through hole; Driving link 2 is a disc, and the one side has boss, also has central through hole; Friction component is by " ┌ " shape part 8, " U " shape part 6 and support spring 5 are formed, " ┌ " shape part 8 one ends are hook-shaped, the curved wedge-like A of the other end, the outside at its place of curving has an arc B, " U " shape part 6 one ends have with described " ┌ " shape part and are the crotch that a hook-shaped end matches, vertical its in-plane of its other end is extended with a pin 5, this pin 5 is inserted in the pin-and-hole on the disc-shaped part of disc driving link 2, have an arc convex C on the external arc of " U " shape part 6, two support arms of support spring 5 are supporting the arc wedge-like end of " ┌ " shape part 8 and the end with pin of " U " shape part 6 respectively; Dc drive motor axle 9 passes driving link 2 centre holes, support spring 5 centers and driven member 1 centre hole, these motor reel 9 terminations have collar 10, the boss of driving link 2 has screw, one screw 3 is solidly connected driving link 2 and motor reel 9 pins, and driving link 2 disk excircles cooperate rotationally with driven member 1 cup-shaped inner periphery.
Described jack can be oil jack, also can be screw type mechanical type jack.
When power turn-on switch 11, dc drive motor 12 rotates, the driving link 2 of the free-wheel clutch on its two end is together with " ┌ " shape part on it 8 and " U " shape part 6 and support spring 5 rotations, when the driving link 2 of electrical motor 12 1 ends (for example jack assembly end) rotates by S direction shown in Figure 2, because the cup-shaped inboard effect of the tapered end A of " ┌ " shape part 8 and driven member 1, therefore driving driven member 1 rotates, thereby carry out the operation of jack stand weight, but 2 of the driven members of the other end (being the air pump assembly end) are pressed J direction rotation shown in Figure 2 simultaneously, this moment, tapered end A can not drive driven member 1 rotation with the cup-shaped inboard effect of driven member 1, at this moment air pump assembly does not move, and only does the jack stand operation.Otherwise, as long as change combining of switch 11 and power supply, electrical motor 12 counter-rotatings, in like manner a pump gas and do not make jack stand and move then.
