Electronic device

1. An electronic device, comprising:

a device body;

a rotary plate hinged to the device body through a rotary shaft and provided with a first guide portion;

a slide plate slidably connected to the rotary plate and provided with a second guide portion, wherein the second guide portion is slidably matched with the first guide portion; and

a flexible display screen connected to the device body and the slide plate respectively, wherein the slide plate slides relative to the rotary plate during switching between an unfolded state and a folded state of the flexible display screen,

wherein the first guide portion comprises multiple comb teeth, and the second guide portion comprises multiple comb teeth grooves, wherein the multiple comb teeth are matched with the multiple comb teeth grooves in a one-to-one correspondence,

wherein a comb tooth is provided with a first positioning flange, and a comb tooth groove is provided with a step portion, wherein the first positioning flange and the step portion are matched in a positioning manner in a direction perpendicular to the slide plate.

2. The electronic device according to claim 1 , wherein the multiple comb teeth comprise a first comb tooth, wherein the first comb tooth is an elastic comb tooth, and one surface, facing the flexible display screen, of the first comb tooth is provided with a first bar-shaped portion and a second bar-shaped portion, wherein both the first bar-shaped portion and the second bar-shaped portion extend along a sliding direction of the slide plate, and a gap exists between the first bar-shaped portion and the second bar-shaped portion.

3. The electronic device according to claim 2 , wherein an end side that is of at least one of the first bar-shaped part and the second bar-shaped part and that faces the flexible display screen is provided with an extension flange, wherein the extension flange is matched with a side wall of a comb tooth groove.

4. The electronic device according to claim 2 , wherein the multiple comb teeth comprise a second comb tooth, and a surface, facing the flexible display screen, of the second comb tooth is a smooth surface, and the first comb tooth and the second comb tooth are matched with different comb teeth grooves respectively.

5. The electronic device according to claim 1 ,

wherein:

at least one comb tooth groove is a trapezoidal groove,

a cross-sectional area of the trapezoidal groove gradually increases in a direction toward the rotary shaft, and

the cross section is perpendicular to a sliding direction of the slide plate.

6. The electronic device according to claim 5 , wherein the multiple comb teeth grooves comprise a first comb tooth groove and a second comb tooth groove, wherein the first comb tooth groove and the second comb tooth groove are alternately arranged, and in a direction toward the rotary shaft, a cross-sectional area of the first comb tooth groove gradually increases and a cross-sectional area of the second comb tooth groove gradually decreases.

7. The electronic device according to claim 1 , wherein the slide plate comprises a main body portion and multiple spacing bars connected to the main body portion,

wherein:

the multiple spacing bars are arranged at intervals,

a comb tooth groove is formed between adjacent spacing bars, and

a spacing bar comprises a first spacing section, a second spacing section, and a third spacing section arranged in sequence, wherein the first spacing section and the third spacing section are rigid structures, and the second spacing section is a flexible structure.

8. The electronic device according to claim 1 ,

wherein:

the slide plate is further provided with a positioning groove,

the rotary plate is further provided with a second positioning flange,

the positioning groove is located at an edge of the slide plate and communicates with a comb tooth groove, and

the positioning groove is matched with the second positioning flange in a positioning manner in a sliding direction of the slide plate.
