Description

Technical Field

[0001] This utility model relates to the field of screw technology, and in particular to a high-precision screw assembly for smart home appliances. Background Technology

[0002] High-precision screw assemblies consist of a lead screw, a guide rod, and a guide rail. Micrometer-level linear positioning is achieved by controlling the number of rotation steps of the lead screw. The screw pitch design directly affects the positioning accuracy, while the accuracy of the guide rail ensures the smoothness of the movement. High-precision screw assemblies are required in the production and processing of smart home appliances to improve the efficiency of the processing.

[0003] Patent CN215171974U discloses a lead screw nut and lead screw nut sleeve mating device. This patent includes a lead screw, a movable bracket, a lead screw nut sleeve, a needle roller bearing, a groove, and a lead screw nut. It replaces the original lead screw nut and adds a lead screw nut sleeve to mate with the lead screw nut, allowing the lead screw nut to float up and down within the sleeve, preventing jamming and improving practicality and efficiency. The lead screw nut can float up and down within the lead screw nut sleeve, and the lead screw nut sleeve is connected to the movable bracket. Therefore, the lead screw and nut can drive the nut sleeve to move back and forth, ultimately driving the extension and retraction of the vehicle-mounted electric retractable wheelchair passage, improving the smoothness of the overall device and extending its service life. Since the weight of the lead screw and slight deformation of the vehicle chassis can cause the lead screw to bend in different directions, the mechanism of the lead screw and nut and the lead screw and nut sleeve cooperating with the lead screw in this invention allows the lead screw and nut a certain degree of vertical and horizontal movement clearance within the lead screw and nut sleeve, thereby preventing the lead screw and lead screw and nut from jamming. However, the following problems still exist in this patent:

[0004] During use, the aforementioned lead screw assembly may generate a lot of heat due to environmental factors, which may cause thermal deformation of the lead screw and lead screw pair may jam. In addition, dust is easy to accumulate inside the lead screw gap, which is troublesome to clean. If it is not cleaned in time, it may affect the efficiency of the lead screw.

[0005] To address the above issues, a high-precision screw assembly for smart home appliances needs to be designed to overcome these problems. Utility Model Content
