The working principle is as follows: when the electric forklift carries goods, the fork arm 1 goes deep into the lower side of the goods and lifts the goods. At the moment, the feedback unit 8 collects the weight of the goods supported by the fork arm 1, whether the fork arm 1 is pressed down relative to the set lifting height, and whether the rear wheel of the electric forklift rises to the ground;
if the weight of the goods supported by the fork arm 1 reaches the set rated weight of the upper bearing limit of the fork arm 1, the judgment control unit 7 controls the air pump to output air, so that the rigid rod 303 rotates downwards to be used as the support of the fork arm 1, and the situation that the electric forklift is tilted due to the fact that the fork arm 1 cannot bear the weight of a supported object is avoided;
if the weight of the goods supported by the fork arm 1 does not reach the set rated weight of the upper limit supported by the fork arm 1, but the forklift encounters a downhill slope in the driving process, the rear wheel of the electric fork is higher than the horizontal height of the front wheel, and the gravity center is close to the fork arm 1, so that the electric forklift is easy to tilt forwards, and at the moment, if the rear wheel of the electric forklift is detected to be lifted off, the judgment control unit 7 controls the air pump to output air, so that the rigid rod 303 rotates downwards to be used as the support of the fork arm 1, and the situation that the fork arm 1 cannot support the weight of a supported object to cause tilting of the electric forklift is avoided;
if the weight of the goods supported by the fork arm 1 does not reach the rated weight of the set upper limit supported by the fork arm 1, the rear wheel of the forklift is not lifted off the ground during running, but the height position of the front end of the fork arm 1 and the set lifting height are lowered, the situation that the fork arm 1 cannot support the weight of the supported object and is bent or about to be broken is determined, the control unit 7 controls the air pump to output air, so that the rigid rod 303 rotates downwards to be used as the support of the fork arm 1, and the situation that the fork arm 1 cannot support the weight of the supported object to cause the bending and breaking of the fork arm 1 is avoided;
when the rigid rod 303 rotates downwards and is vertical to the fork arm 1, the fork arm 1 is connected and supported with the ground; wherein, the vesicle 202 is full of gas, effectively avoids electric fork truck on the way, runs into jolt rigidity pole 303 and yoke 1 and produces direct rigid contact, causes the cracked problem of rigidity pole 303 to take place, has effectively slowed down the dynamics and the contact velocity of rigid contact, has effectively prolonged part life.
The second embodiment is as follows: in contrast to the first embodiment, referring to fig. 7-9, the buffering unit 2 includes a buffering housing 204 and a buffering piston 206; a closed buffer cavity 205 is formed in the buffer shell 204, and the buffer cavity 205 is filled with buffer solution; the cushion piston 206 is slidably connected to the cushion chamber 205, and the cushion piston 206 is provided with a through damper hole 207.

The working principle is as follows: when the rigid rod 303 rotates downwards to form a vertical state with the fork arm 1, the buffer piston 206 is positioned at the lower side in the buffer cavity 205 due to the self-weight; under this state, when electric fork-lift truck runs into jolting in the journey, rigid bar 303 moves upwards, because the effect of damping hole 207 and buffer, can slow down the vibration of rigid bar 303, reduces the direct influence to yoke 1, effectively avoids vibrating too big problem emergence that leads to the goods to drop or damage to yoke 1. Meanwhile, the buffer cavity 205 and the buffer piston 206 are both located inside the buffer shell 204, so that damage to the component due to external force collision is effectively avoided, and the service life of the component is effectively prolonged.

when the rigid rod 303 rotates downwards and is perpendicular to the fork arm 1, the buffering elastic piece 209 is extruded and embedded into the limiting groove 101, and the buffering shell 204 and the rigid rod 303 are limited, so that the problem that the rigid rod 303 is not perpendicular to the fork arm 1 and loses the supporting function on the fork arm 1 due to the fact that the rigid rod 303 rotates and inclines inwards under the action of external force is effectively avoided;
when the rigid rod 303 rotates downwards to form a vertical state with the yoke 1, in this state, when the yoke 1 of the electric forklift is slightly shaken during running, the elastic compensation of the buffering elastic piece 209 is relied on, so that the problem that the rigid collision of the rigid rod 303 causes the service life of the rigid rod 303 to be shortened is effectively avoided.
