1. Integration of functional modules
The compact internal structure design of the Handheld power tools Wallpaper machine is first reflected in the integration of functional modules. Wallpaper machines usually include multiple functional modules such as motors, transmission systems, glue coating devices, and wallpaper conveying mechanisms. In the design, it is key to highly integrate these functional modules. For example, the motor is closely integrated with the transmission system, and the power transmission path is minimized through optimized gear sets or belt drives.
The small and efficient motor is directly installed near the wallpaper conveying roller, reducing the length and number of intermediate transmission components. At the same time, the glue coating device and the wallpaper conveying mechanism are integrated, so that the glue coating and wallpaper conveying can be completed in a compact space. This integrated design not only saves a lot of internal space, but also improves the coordination efficiency between the functional modules, and reduces the power loss and failure probability that may occur due to the dispersion of components.
2. Use of miniaturized and customized components
In order to achieve a compact internal structure, handheld electric Wallpaper machines use a large number of miniaturized and customized components. In terms of motor selection, small motors with high power density are preferred. These motors have a significantly reduced volume while ensuring sufficient power output. For example, the new brushless DC motor can reduce the volume by 30%-50% compared with the traditional motor at the same power.
In addition to the motor, other components are also mostly customized. For example, the transmission gear adopts a special modulus and number of teeth to make it as small as possible while meeting the strength requirements. The internal circuit board is also carefully designed to remove unnecessary redundant components, and adopt multi-layer wiring and small packaging chip technology to greatly reduce the area of the circuit board. These miniaturized and customized components can be arranged tightly in a limited space, thus achieving the compactness of the internal structure of the wallpaper machine.
3. Reasonable space layout and wiring planning
Reasonable space layout and wiring planning are crucial to the compact design of the handheld electric wallpaper machine. In terms of space layout, reasonable arrangements are made according to the frequency of use, degree of mutual correlation and heat dissipation of each functional module. Frequently used and closely related components, such as motors and transmission systems, are placed in the core area close to the handheld part to facilitate operation and power transmission.
For components that generate more heat, such as motors and power components on circuit boards, a certain amount of heat dissipation space will be reserved, and they will be separated from temperature-sensitive components (such as glue storage devices). In terms of wiring planning, flat cables and hidden wiring methods are used to arrange power cables, signal cables, etc. along the edge of the wallpaper machine's shell or the grooves of the internal frame to avoid the cables from being cluttered in the internal space, thereby making full use of every inch of space and making the entire internal structure appear more compact and orderly.
4. Optimize the design of the shell and internal frame
The optimized design of the shell and internal frame also contributes to the compactness of the handheld electric wallpaper machine. The shell is made of high-strength, thin-walled engineering plastics or lightweight metal materials. While ensuring sufficient mechanical strength to protect the internal components, the wall thickness is reduced as much as possible, thereby increasing the internal available space.
The design of the internal frame fully considers the installation and positioning of each component. The frame is equipped with precise card slots, screw holes and positioning pins, so that each component can be accurately and compactly installed in the predetermined position. For example, by setting up multiple layered slots on the frame, circuit boards and small components of different thicknesses can be layered and fixed to make full use of the vertical space. This coordinated design of the shell and the internal frame provides a solid foundation for realizing the compact internal structure of the handheld electric wallpaper machine.
