2results about How to "Less prone to interference" patented technology

This utility model relates to the field of snow-throwing machine technology, and more particularly to a snow-throwing tube structure and a snow-throwing robot. The snow-throwing tube structure includes a tube body, a guide shell, a rotary drive assembly, an outer volute cover, and an inner volute cover. The guide shell is rotatably connected to the tube body. The outer volute cover is mounted on the guide shell, and a first internal space is provided between the outer volute cover and the guide shell. The inner volute cover is mounted on the tube body, and a second internal space communicating with the first internal space is provided between the inner volute cover and the tube body. One end of the inner volute cover is slidably inserted into the first internal space. The rotary drive assembly is mounted on the tube body, located in the first and second internal spaces, and connected to the guide shell, for driving the guide shell to rotate relative to the tube body. In this utility model, the rotary drive assembly and other components are always located in the sealed first and second internal spaces, avoiding interference from the external environment. The inner and outer volute covers also provide insulation for the rotary drive assembly.

This application discloses a battery device and an electrical device. The battery device includes: a housing; multiple battery cells, each having a casing and an electrical connection portion. In a first direction, the electrical connection portion is located on one side of the casing, and the multiple battery cells are electrically connected via electrical connectors. The housing has a first cavity wall opposite to the electrical connectors. A support structure is at least partially located between the casing and the first cavity wall, with a minimum distance between the support structure and the first cavity wall that is less than the minimum distance between the electrical connectors and the first cavity wall. At least one support structure is a first support structure and includes a first support portion and a second support portion connected together. The first support portion is located between two adjacent electrical connectors, and the second support portion is located between the casing and the electrical connectors. In the above technical solution, the support structure can transmit and disperse the external impact force borne by the first cavity wall. The first support structure can support the electrical connectors and increase the mating area with the casing, effectively reducing the risk of damage to the electrical connection structure.
