The specific embodiment
Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 2 is the structural representation of the utility model scheme one.As shown in Figure 2, the agent structure of the utility model lifting driver train is made up of base 3, piston mechanism 1 and push rod 2.Wherein, the cylinder barrel 12 of piston mechanism 1 is connected with base 3 by servo-actuated bindiny mechanism 4, can adopt hinge to connect with being dynamically connected or bearing pin connection or buckle bonded assembly movable connection method, one end of push rod 2 is captiveed joint with the piston 11 of piston mechanism 1, the other end of push rod 2 is captiveed joint with an end of front fork 5, certainly push rod 2 also can be integral structure with front fork 5, and the other end of front fork 5 is with hinged by lifting thing 7.Described servo-actuated bindiny mechanism 4 moving connecting mechanism in other words is made up of bearing pin 41, support 42 and Rocker arm 43, and bearing pin 41 is hinged with support 42 and Rocker arm 43, and support 42 is fixed on the base 3, and Rocker arm 43 is fixed on the cylinder barrel 12 of piston mechanism 1.After pressurized air enters cylinder from admission port 13, promote piston 11 motions, the push rod 2 of captiveing joint with piston 11 is made corresponding sports, and acts on by lifting thing 7 by front fork 5, makes by the attachment point deflection of lifting thing 7 around its lower end, and its upper end descends.After the pressurized air of cylinder disappears, risen by lifting thing 7 upper end under the restoring force effect, get back to initial position thereby drive push rod 2 promotion pistons 11.
In above-mentioned working process, because by the attachment point deflection of lifting thing 7 around its lower end, so will drive push rod 2 deflections, as shown in Figure 3.Because the utility model is arranged to servo-actuated bindiny mechanism 4 with piston mechanism 1 and being connected of base 3, makes piston mechanism 1 with push rod 2 deflections, therefore make the axial direction of push rod 2 identical with piston 11 axial directions all the time.Specifically, the hinge of support 42 and Rocker arm 43 is connected can make the two deflection physical alterations connection angle with push rod 2, and the deflection angle of cylinder barrel 12 is identical with the deflection angle of push rod 2, therefore make the force direction of push rod 2 identical with piston 11 axial directions all the time, make piston can not be subjected to the non-axial force effect, neither can make piston impaired, can keep permanent sealing effectiveness again.
Fig. 4 is the structural representation of the utility model scheme two.As shown in Figure 4, the agent structure of the utility model lifting driver train is made up of base 3, piston mechanism 1 and push rod 2 and pilot bar 6.Wherein, the cylinder barrel of piston mechanism 1 12 is by fixed connecting piece 4 ' captive joint with base 3, and an end of push rod 2 is captiveed joint with the piston 11 of piston mechanism 1, and the other end of push rod 2 passes through pilot bar 6 and is connected by lifting thing 7.Specifically, an end of front fork 5 and pilot bar 6 is hinged, and the other end of front fork 5 is captiveed joint with push rod 2, and the other end of pilot bar 6 is hinged on by on the lifting thing 7.After pressurized air enters cylinder from admission port 13, promote piston 11 motions, the push rod 2 of captiveing joint with piston 11 is made corresponding sports, and acts on by lifting thing 7 by front fork 5, pilot bar 6, make by the attachment point deflection of lifting thing 7 around its lower end, its upper end then descends.After the pressurized air of cylinder disappears, risen by lifting thing 7 upper end under the restoring force effect, get back to initial position thereby drive push rod 2 promotion pistons 11.
In above-mentioned working process, because by the attachment point deflection of lifting thing 7 around its lower end, so drive pilot bar 6 deflections, as shown in Figure 5.Since the utility model with push rod 2 be arranged to pilot bar 6 by being connected between the lifting thing 7, when being risen or descending by lifting thing 7, pilot bar 6 is made corresponding deflection, and push rod 2 with support sleeve 21 effects of its bearing fit under the maintenance direction constant.Specifically, be connected by the hinge of lifting thing 7, pilot bar 6 and front fork 5 and can make pilot bar 6 with by the deflection physical alterations connection angle of lifting thing 7, thereby the direction that guarantees push rod 2 is constant, make the force direction of push rod 2 identical with piston 11 axial directions all the time, make piston can not be subjected to the non-axial force effect, neither can make piston impaired, can keep permanent sealing effectiveness again.
One end slip cap of described support sleeve 21 is connected on the push rod 2, and the other end is captiveed joint with base 3.Therefore, push rod 2 can only move along the direction that support sleeve 21 limits.
When the technical scheme of Fig. 2, lifting driver train shown in Figure 4 is applied to the power connection equipment of electric vehicle, promptly can be used for driving the rising and the decline of trolley pole, realize electric vehicular traffic automatically to line or off-line.Wherein, be trolley pole by lifting thing 7, piston mechanism 1 adopts air operated control, and base 3 is fixed on vehicle roof.Its structure is identical with the aforementioned techniques scheme, repeats no more.
Be the specific embodiment of the present utility model only below, but in any form the utility model do not made restriction.Should be pointed out that for a person skilled in the art, according to design concept of the present utility model; can also make a lot of distortion and improvement; for example, the air pressure mode also can be changed into hydraulic way or electromagnetic mode etc., but these all will fall into protection domain of the present utility model.
