Smart forklifts are widely used in warehousing logistics, production and manufacturing, e-commerce logistics and other fields. They can improve logistics operation efficiency, reduce labor costs, and improve operation safety and accuracy.

[0003] With regard to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: with the rise of the smart forklift industry, most steering wheels with a wheel diameter of more than 300 mm on the market do not have a shock-absorbing structure suitable for smart forklifts. When the forklift is used on different surfaces, it cannot meet the special requirements of relatively uneven road conditions indoors.

[0004] Therefore, the utility model provides a steering wheel shock absorbing mechanism. Utility Model Content

[0007] Preferably, the surfaces of the two adjusting bolts are both provided with anti-slip protrusions.

[0008] In summary:

[0009] In the utility model, a fixed vehicle body upper plate, a fixed steering wheel upper plate, a boost adjustment plate, a shock absorbing spring, a fixed steering wheel lower plate, and a fixed vehicle body lower plate are strung together by connecting a long axis and can slide up and down in the vertical direction of the connecting long axis. The fixed vehicle body upper plate, the fixed steering wheel upper plate, the boost adjustment plate, the fixed steering wheel lower plate, and a first oil-free bushing is installed in a hole of the fixed vehicle body lower plate, and the first oil-free bushing is fixed by bolts. The steering wheel is bolted and fixed to the steering wheel connecting plate, and the fixed steering wheel upper plate and the fixed steering wheel lower plate are bolted to form a whole that can slide up and down along the long axis. The fixed vehicle body upper plate is fixed to the intelligent forklift body, and the first oil-free bushing is fixed by bolts. The second oil-free bushing bolt is fixed to the upper plate of the fixed steering wheel, the boost shaft passes through the second oil-free bushing, and the adjusting bolt is tightened to press the boost shaft downward, thereby pressing the boost adjustment plate downward, adjusting the position of the boost adjustment plate, and controlling the compression amount of the shock absorber spring. The long-axis fixed cover plate is fixed to the upper plate of the fixed vehicle body to prevent the shaft from moving upward, and the upper plate of the fixed vehicle body is locked on the vehicle body and fixed, and the long axis is fixed. After the adjusting bolt is adjusted, the boost shaft and the boost adjustment plate are fixed, connecting the steering wheel and the steering wheel connecting plate, fixing the steering wheel upper plate, and fixing the steering wheel lower plate as a whole. When the steering wheel encounters a raised ground, it is subjected to an upward force, thereby driving the connection The steering wheel is connected to the steering wheel, the upper plate of the steering wheel is fixed, and the lower plate of the steering wheel is fixed and moves upward as a whole. The lower plate of the steering wheel is fixed to press the spring upward, and the spring presses the boost adjustment plate upward. The boost adjustment plate is fixed, and the spring produces elastic deformation, thereby avoiding the overall upward vibration of the vehicle body. When walking on the concave ground, the spring elastic force and the steering wheel's own gravity make the steering wheel move downward, and the steering wheel can still play a driving role to avoid slipping. This product is an integrated device that integrates shock absorption with the steering wheel. It can be directly installed on the frame back plate of the smart forklift. Only positioning holes and bolt holes need to be opened for easy installation and disassembly. The steering wheel spring is in normal condition before installation. In the unstressed state, when installed in the air on the vehicle body, the steering wheel protrudes 10-40mm from the ground under the vehicle. After the steering wheel touches the ground, the spring is stressed and has a certain pre-compression. The spring pre-compression can be adjusted by replacing the spring according to the vehicle load, so as to achieve the corresponding shock absorption effect. The pre-tightening force generated by the spring can also be adjusted according to the usage by tightening the bolts to adapt to different working conditions. The utility model can be used for the shock absorption and buffering function of large steering wheel intelligent forklifts, and the spring compression length can be adjusted according to different working conditions. The spring can also be replaced according to different vehicle loads. It has a variety of adjustability to cope with different road conditions and is suitable for more scenarios.
