Abstract
The invention discloses a push rod device for switching power for an electric automobile. The push rod device comprises a shell and a lockable air spring, wherein the axis of the lockable air spring extends along the forward-backward direction; the tail end of a piston rod of the air spring is hinged to the shell; the tail end of an air spring cylinder extends forwards out of the shell to form a force application end for pushing a battery box; a front support which is matched with a sliding support of the air spring cylinder is arranged in the shell; and the shell is also provided with a control mechanism for controlling opening and closing of an air spring button. Since the air spring is adopted in the shell, the forward-backward stretch of the air spring cylinder is realized under the control effect of the control mechanism, the thrust produced thereby is sufficient to meet the requirements of draw-out of the battery box, and the battery box can be pushed in smoothly even though the battery box is blocked.

Work technique and the impact in mechanical spring life-span, general thrust is less, so in the case of battery case runs into catching phenomenon, is difficult to
Battery case is pushed in, in turn results in and change electricity failure；In addition, the push rod of this transfer bar mechanism can only move along a straight line, once run into
Battery case tilts just to easily cause push rod torsional deformation.
Content of the invention
It is an object of the invention to provide a kind of disclosure satisfy that electric motor vehicle cell box extracts the push rod device needing, in order to solve
The less problem of thrust of electric putter device offer is now provided.
The present invention adopts the following technical scheme that：A kind of electric automobile changes electricity push rod device, including housing and be located at
The lockable gas spring that in housing, axis extends along the longitudinal direction, air spring piston bar end is hinged on housing, gas spring
The tip forward of cylinder body is stretched out housing and is formed force side for pushing tow battery case, being provided with and gas spring cylinder slides in housing
The front support of support cooperation；The controlling organization controlling gas spring button opening and closing is additionally provided with housing.
Described front support is float support, and front support includes guiding sliding sleeve on gas spring cylinder for the slip cap and right
Claim to be arranged in the extension spring of gas spring cylinder arranged on left and right sides, one end of extension spring is connected with described sliding sleeve, the other end and housing corresponding
Side wall connects.
One end away from gas spring of described each extension spring is screwedly mounted on the regulation spiral shell on housing left and right side wall by spiral respectively
Nail is connected on housing, and the corresponding end of each extension spring is connected in the adjusting screw of respective respective side.
Described controlling organization include being inserted on housing, can swing driving lever, one end of driving lever is stretched in housing,
And it is connected with drawstring between inserting end and the connecting lever pressing plate controlling gas spring button.
Using the push rod device of said structure, due to adopting gas spring in housing, under the control action of controlling organization, real
Now gas spring cylinder is elastic, and it produces the needs that thrust is sufficient for battery case extraction, even if battery case runs into clamping stagnation
Battery case also can smoothly be pushed in by phenomenon.

Fig. 2 is working state figure of the present invention；
Fig. 3 is the A-A of Fig. 1 to sectional view；
Fig. 4 is the external structure schematic diagram of the right view of Fig. 1.
Specific embodiment
The embodiment of push rod device of the present invention：As Figure 1-4, including housing 1, it is provided with axis in housing 1 along front and back
To the lockable gas spring extending, gas spring is existing device, mainly by gas spring cylinder 5, the gentle spring of air spring piston bar 2
Button 9 is constituted, and wherein gas spring button 9 is used for controlling the flexible of gas spring, and gas spring button 9 is then controlled by connecting lever pressing plate 10
Its pressure or ejection；The end of air spring piston bar 2 is passed through the first vertically extending bearing pin 11 of axis and is hinged on housing 1
Interior, housing front side wall is stretched out in the end of gas spring cylinder 5, is additionally provided with and props up before gas spring cylinder 5 is supported in housing 1
Support, front support is slidably matched with gas spring cylinder 5 guiding, so passes through to control gas spring button 9, achievable gas spring cylinder 5
Elastic motion, the external part of gas spring cylinder 5 is force side.In the present embodiment, the control of connecting lever pressing plate 10 is by controlling
Mechanism processed realizes, and controlling organization includes the driving lever 7 being inserted in housing right side wall, connects between driving lever 7 and housing right side wall
It is connected to the second bearing pin 12 that can make driving lever swing, simultaneously in order to meet the swing needs of driving lever 7, the hole in housing right side wall
The elongated hole that the hole position that driving lever 7 passes through extends along the longitudinal direction；One end of driving lever 7 is stretched in housing 1, and inserting end and control gas bullet
It is connected with steel wire rope 8, steel wire rope 8 is to be in transmission connection between driving lever 7 and connecting lever pressing plate 10 between the connecting lever pressing plate 10 of spring button 9
Drawstring, during driving lever 7 forward swing, as shown in Fig. 2 steel wire rope 8 applies, to gas spring button 9, the active force that pushes, realize
The opening of gas spring, conversely, gas spring button 9 ejects, gas spring is closed.
As optimizing further, described front support is float support, including guiding slip cap on gas spring cylinder 5
Sliding sleeve 6 and the extension spring 3 being arranged symmetrically in gas spring arranged on left and right sides, one end of extension spring 3 is connected on sliding sleeve 6, extension spring 3 another
One end is connected in the housing sidewall of respective respective side, so relies on the pulling force of two extension springs 3 to realize propping up of gas spring cylinder 5
Support, the elastic force of extension spring simultaneously, enable gas spring free floating in the external force by any direction, and then avoid because of battery
Case tilts and causes the phenomenon of air spring piston bar deformation to occur.
As optimizing further, in order to ensure the stress balance of gas spring, on housing left and right side wall respectively from outside to inside
Spiral has been screwed adjusting screw 4, and one end away from gas spring of each extension spring 3 is connected to the adjusting screw 4 of respective respective side
On, the adjustment effect relying on adjusting screw 4 is it can be ensured that the stress balance of gas spring cylinder 5.
In other embodiments, front support can also be the fixing support being installed on housing, and such gas spring cylinder is only
Can linear motion.
In other embodiments, controlling organization can also be connected to the drawstring on gas spring button, drawstring only with one end
The other end stretch out housing, directly pass through the opening and closing pulling drawstring also to enable gas spring button.
