[0025] See also Figure 1 , Figure 1 This is an exploded schematic diagram of a folding screen hinge cover fixing device according to the present application. The present application provides a folding screen hinge cover fixing device 1, comprising: a lower box body 11, an upper box body 12, and a stopper 13. The upper box body 11 and the lower box body 12 are connected and enclosed to form a folding screen fixing area. The stopper 13 is arranged in the folding screen fixing area and is clamped to both sides of the folding screen hinge along the axial direction of the folding screen hinge, abutting against the folding screen hinge cover.

[0026] Please also see Figure 2 , Figure 2 This is a schematic diagram of a folding screen rotation axis and a folding screen rotation axis cover of a folding screen rotation axis cover fixing device of the present application. The folding screen mobile phone 2 includes a folding screen rotation axis 23 and a folding screen rotation axis cover 24. The folding screen mobile phone 2 is connected through the folding screen rotation axis 23 and rotates around it to implement unfolding or folding. The folding screen rotation axis 23 is set in the folding screen fixing area. The folding screen rotation axis 23 is provided with a folding screen rotation axis cover mounting portion, and the folding screen rotation axis cover 24 is set in the folding screen rotation axis cover mounting portion by gluing, wherein the folding screen rotation axis cover mounting portion can be a groove or an interface.

[0027] The stoppers 13 surround the folding screen hinge cover, are clamped on both sides of the folding screen hinge 23, and abut against the folding screen hinge cover 24. The stoppers 13 act as a limiter for the folding screen hinge cover 24, effectively preventing the folding screen hinge cover 24 from deviating toward the edge of the folding screen hinge 23. Furthermore, the stoppers 13 do not directly press the folding screen hinge cover 24, thus preventing deformation of the folding screen hinge cover 24.

[0028] In addition, after the lower box body 11 is connected to the upper box body 12, a relatively closed environment can be provided for the glue solidification process, which helps to reduce the interference of external factors on the glue curing, such as dust and water vapor, thereby ensuring the bonding quality between the folding screen hinge cover 24 and the folding screen rotating shaft 23.

[0029] In this embodiment, the limiting member 13 can be two long limiting strips. When projected along the axial direction of the limiting strip 13, the cross section of the limiting strip 13 is L-shaped. Figure 3 The two limiting strips 13 are respectively engaged with the right angles of the two side frames of the folding screen rotation axis 23 through their L-shaped structures, and are respectively in contact with the two sides of the folding screen rotation axis cover 24.

[0030] In one embodiment, the upper box body 12 is recessed inward to form a second receiving groove, and the limiting strip includes a limiting portion 131 and a fixing portion 132 that are perpendicular to each other. After the limiting portion 131 and the fixing portion 132 are clamped at right angles with the frame of the folding screen rotation axis 23, the limiting portion 131 abuts against the folding screen rotation axis cover 24; after the upper box body 12 is connected to the lower box body 11, the fixing portion 132 abuts against the inner wall of the second receiving groove.

[0031] The limiting parts 131 of the two limiting strips 13 are respectively clamped on both sides of the folding screen rotation axis 23, and the fixing part abuts against the inner wall of the second receiving groove, thereby realizing the abutment of the limiting strips 13 on both sides of the folding screen rotation axis cover 24. The folding screen rotation axis cover 24 is restricted from deviating toward both sides of the folding screen rotation axis 23. Of course, in other embodiments, the shape and number of the limiting strips 13 can be adaptively adjusted according to the actual shape of the folding screen rotation axis 23. For example, when groove structures are provided on both sides of the folding screen rotation axis 23, the limiting strips 13 can be correspondingly provided as convex structures, thereby matching the groove structures on the folding screen rotation axis 23 to form a stable limiting relationship.

[0032] Please also see Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the lower box body of a folding screen hinge cover fixing device of this application.

The receiving seat 112 and the connecting seat 111 can be integrally formed or fixedly installed by welding.

[0034] By providing the receiving seat 112, when glue is applied to the rotating shaft 23, the folding screen is placed in the first receiving groove, which facilitates clamping and securing the lower box body 11 to complete the glue application. After the glue application and the bonding of the folding screen rotating shaft cover 24 are completed, the limiting member 13 can be directly nested with the folding screen rotating shaft 23 to complete the fixed position of the folding screen rotating shaft cover 24, effectively improving work efficiency.

[0035] The upper case 12 is provided with a plurality of guide posts 121, and the connecting base 111 is provided with a plurality of mounting holes 111a corresponding to the guide posts 121. The guide posts 121 are arranged around the second receiving slot, and the mounting holes 111a are arranged around the opening 111d corresponding to the guide posts 121.
