5results 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.

The object of the present invention is to provide a method for manufacturing an adhesive sheet and an adhesive sheet obtained by the manufacturing method, wherein even when an additive is added to the adhesive sheet, the change in the physical properties of the adhesive sheet and the interference between the additives are suppressed to a minimum, and the freedom of design of the selection of additives, curing conditions, etc. is increased to facilitate design. The manufacturing method of the adhesive sheet of the present invention is characterized in that it includes the following steps: forming an adhesive layer 10 formed of a transparent adhesive matrix material on a support S, curing the adhesive layer 10, preparing a solution 12 of an additive 11, applying the solution 12 on one surface of the cured adhesive layer 10a, allowing the additive 11 contained in the solution 12 to penetrate from the one surface of the adhesive layer 10a along the thickness direction, and drying the adhesive layer 10a.

The invention belongs to the field of electronic equipment, and provides a circuit board assembly and an earphone, the earphone comprises the circuit board assembly, the circuit board assembly comprises a PCB and a switch member, the thickness direction of the PCB is a first direction, the PCB is provided with a front surface, a back surface and a side surface, the front surface and the back surface are oppositely arranged along the first direction, and the side surface is arranged between the front surface and the back surface along the first direction; the switch piece is integrated on the side. According to the circuit board assembly, the switch piece is integrated on the side face of the PCB, the situation that the switch piece occupies the space of the side where the front face and the back face of the PCB are located is effectively avoided, the layout is reasonable, electronic components on the front face or the back face of the PCB are not prone to interference, and the technology difficulty and the production cost of products can be reduced; therefore, in the earphone assembling process, when the circuit board assembly, the battery, the loudspeaker and other assemblies are arranged in a stacked mode in the first direction, the switch piece is not prone to being collided, and the yield can be improved.

The invention provides compression molding equipment, a foaming part production system and a compression molding method, and relates to the technical field of foaming part production, and the compression molding equipment comprises a rack, a moving seat, a lifting oil cylinder, a turnover oil cylinder and a compression molding oil cylinder. The rack is provided with a base; the base is fixedly connected with a lower die of the forming die; the moving seat is arranged above the base and used for being fixedly connected with an upper die body of the forming die. The lifting oil cylinder is arranged on the first side of the movable base, a cylinder body of the lifting oil cylinder is vertically and fixedly installed on the rack, and a piston rod of the lifting oil cylinder is upwards hinged to a part A on the movable base. The overturning oil cylinder is arranged above the first side close to the moving seat and inclines towards the first side of the moving seat, the first end of the overturning oil cylinder is hinged to the rack, and the second end of the overturning oil cylinder is hinged to the moving seat; the pressing die oil cylinder is arranged over the movable base, the first end of the pressing die oil cylinder is hinged to the rack, and the second end of the pressing die oil cylinder is hinged to the movable base. When the compression molding equipment is used for molding large products, the operation convenience and the molding precision can be guaranteed at the same time, and the interference phenomenon can be avoided.

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.
