Description

Technical Field

[0001] The utility model belongs to the technical field of smart home product design, and particularly relates to a housing for an electric flip drive. Background Art

[0002] With the rapid development of technology and the increasing improvement of people's living standards, smart home products such as smart toilets, dishwashers, and smart washing machines have been widely used in modern families. These smart home products not only improve the convenience of life but also significantly enhance the quality of life. Among these products, the electric flip function, as an important intelligent feature, greatly improves the user experience. However, there are still some technical bottlenecks and deficiencies in the design and manufacturing of the widely used electric flip drives on the market.

[0003] Most of the existing electric flip drives adopt a plastic housing design to reduce the overall volume and weight, facilitating installation and use. However, due to the characteristics of the plastic material itself, especially the relatively thin wall thickness designed to reduce the volume, the drive is prone to deformation when operating for a long time or under a large reaction force. This deformation not only affects the appearance beauty of the drive but more importantly, may cause the loosening of the internal structure of the drive, thereby affecting the stability and reliability of its flipping function.

[0004] In addition, most of the existing drive housings use a screw connection method to fix each component. Although this connection method ensures the structural stability to a certain extent, it also brings problems such as complex installation and inconvenient maintenance. At the same time, the stress concentration phenomenon at the screw connection may also cause cracks or fractures in the drive during use, further reducing its service life and safety.

[0005] In view of the above problems, there is an urgent need in the market for a new type of electric flip drive that can significantly improve the structural strength and durability while maintaining a small volume and light weight, reducing the risk of functional failure caused by deformation and loosening.

Users or maintenance personnel can more easily access and replace each component, reducing the maintenance cost and time. This modular design also helps to quickly locate the problem when a fault occurs, improving the repair efficiency.

[0047] Improving Transmission Efficiency and Performance:

[0048] The independent design of the power unit installation chamber and the transmission device installation chamber enables the motor and the transmission device to work more efficiently. It reduces the energy loss during the transmission process and improves the transmission efficiency. At the same time, this design also helps to optimize the transmission ratio and power output, enabling the driver to more accurately control the movement of the flap and improving the overall performance.

Whether it is a high-power or low-power motor, the best space utilization and assembly effect can be achieved by adjusting the inclination angle.

[0062] Improve transmission efficiency:

[0063] The inclined support plates also help to optimize the transmission path of the motor and reduce the energy loss during the transmission process. Since the relative positions between the motor and the transmission device are more reasonable, the transmission efficiency is improved, thereby enhancing the overall performance of the driver.

[0064] In summary, this technical feature optimizes the space utilization and structural compactness of the driver by inclining the first motor shaft end support plate and the first motor tail end support plate, enhances its adaptability to motors of different specifications, and improves the transmission efficiency.
