When the heart needs to adjust forward, vertical adjustment stepper motor 402 is rotated forward, and drives vertical adjustment lead screw by vertical adjustment lead screw 404
Nut 403 travels forward, and under the drive of vertical adjustment feed screw nut 403, lateral adjustments support baseboard 306 drives vertical adjustment
The forward slip on vertical adjustment sliding rail 401 of sliding block 405 realizes that power battery 1 travels forward, reaches the mesh that center of gravity is adjusted forward
, vice versa.
When the range of center of gravity regulatory demand longitudinally forward is larger, vertical adjustment sliding block 405 passes through fastening spring hinge 406
Pinch wheels 413 are driven to move forward with pinch wheels support plate 407, pinch wheels 413 and such as Fig. 7 institute of pinch wheels support plate 407
Show, when pinch wheels 413 touch the scalable sliding rail 412 of vertical adjustment and move forward, pinch wheels 413 provide clamping force
The scalable sliding rail 412 of vertical adjustment is stretched out, and forms straight line with vertical adjustment sliding rail 401, as shown in figure 5, making longitudinal direction
Adjusting slider 405 can be slided into successfully on the scalable sliding rail 412 of vertical adjustment, realize the larger range of forward of center of gravity longitudinal direction
It adjusts.It is longitudinal to adjust when vertical adjustment sliding block 405, which moves rearwards to pinch wheels 407, is separated from the scalable sliding rail 412 of vertical adjustment
It saves scalable sliding rail 412 to retract under the opening force effect for opening spring hinge 415, make at the scalable sliding rail 412 of vertical adjustment
In in the security protection frame of electric tractor.
As shown in fig. 6, passing through fixing bolt 410 in support plate when the scalable sliding rail 412 of vertical adjustment is stretched out or retracted
The fixing bolt 409 under fixing bolt 410 in support plate and support plate of support plate 411 is driven to rotate, in vertical adjustment sliding block 405
When sliding on the telescopically adjustable sliding rail 412 of vertical adjustment, support plate can play the work for bearing most of gravity of power battery 1
With.The vertical adjustment power that scalable sliding rail freely retracts can be provided by opening spring hinge 415, but the power is than fastening spring hinge
The clamping force of 406 offers is small, and the clamping force for enabling pinch wheels 413 to apply is relatively easily by the scalable sliding rail of vertical adjustment
412 stretch out.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring substantive content of the invention.

The scalable sliding rail of vertical adjustment, when vertical adjustment needs bigger adjustable range, the scalable sliding rail of vertical adjustment
It stretches out, forms straight line with vertical adjustment sliding rail, vertical adjustment sliding block is slid on the scalable sliding rail of vertical adjustment, is realized bigger
The longitudinal center of gravity of range is adjusted, and by the support of support plate, so as to bear greater weight battery；
The pinch wheels, for stretching out the scalable sliding rail of vertical adjustment to the scalable sliding rail applied force of vertical adjustment；
The electric tractor stringer, for fixing, supporting vertical adjustment sliding rail and vertical adjustment lead screw firm banking；
The opening spring hinge, for providing the opening force of the scalable sliding rail of vertical adjustment, thus do not need it is wider
When vertical adjustment, retract the scalable sliding rail of vertical adjustment.
6. a kind of electric tractor gravity adjusting device according to claim 5, which is characterized in that the opening spring closes
Page opens the opening force that spring hinge provides and had been able to satisfy the opening of the scalable sliding rail of vertical adjustment not only to reach retraction effect, but also
Being able to satisfy the scalable sliding rail of vertical adjustment can be easier to stretch out under the action of pinch wheels.
