Technical Field
[0001] The utility model relates to the technical field of material carts, in particular to a shock-absorbing material cart for a traction-type AGV. Background Art
[0002] AGV (Automated Guided Vehicle) is an automated guided vehicle that can automatically travel along a set route. With the continuous advancement of technology, there are many different AGVs on the market. For example, the fork-type AGV can use the fork to replace manual labor to load and unload materials, greatly improving the efficiency of the entire transportation process. Another example is the traction AGV, which is combined with a material cart to form a material handling device, so that the material cart can transport materials under the guidance of the traction AGV.
[0003] However, in actual applications, traction AGVs often encounter various complex road conditions when towing material carts for transportation, such as uneven roads, potholes, steps, etc. These uneven road conditions can cause the material cart to bump, which in turn causes the materials and equipment loaded on the material cart to slide and cause damage, especially for some fragile, sensitive or high-precision materials. This damage is particularly serious and may cause material damage, equipment failure, and even affect the normal operation of the entire production line. Utility Model Content
