[0019] Example 1: A drop-resistant foldable electronic device includes a base 21 and a rotatable screen 22. A lower plate 1 is mounted on the base 21. The rotatable screen 22 is rotatably connected to the lower plate 1 through two spaced upper plates 2. Each end of the lower plate 1 has a vertically downward bending portion 12. The front end of each bending portion 12 has a mounting portion 13 extending to the outside of the base 21. A rotating shaft 3 is mounted on the mounting portion 13. The two upper plates 2 are correspondingly fitted onto the two rotating shafts 3 and can rotate around the rotating shafts 3.

[0020] The mounting part 13 has two spaced-apart first protrusions 91 and second protrusions 92 on one end near the upper plate 2. When the upper plate 2 is in a vertical 90° position, the first protrusion 91 is in line contact with the upper plate 2. When the upper plate 2 is in a 130° position, the second protrusion 92 is in line contact with the upper plate 2. The areas of the first protrusion 91 and the second protrusion 92 that are in contact with the upper plate 2 are arc-shaped.

[0021] The rotating shaft 3 has a flange 4 located between the lower plate 1 and the upper plate 2. A support plate 5 is rotatably mounted on the rotating shaft 3 and connected to the upper plate 2. One end face of the support plate 5 is in contact with the flange 4. A spring 6 is mounted on the rotating shaft 3 between the other end face of the support plate 5 and the upper plate 2. Several spring pieces 7 are mounted on the rotating shaft 3 on the side of the upper plate 2 opposite to the spring 6 and are pressed and fixed by nuts 8.

[0022] A washer 10 is provided between each end of the spring 6 and the upper plate 2 and the support plate 5.

[0023] The through hole connecting the mounting part 13 and the rotating shaft 3 is a square through hole.

[0024] Example 2: A drop-resistant foldable electronic device includes a base 21 and a rotatable screen 22. A lower plate 1 is mounted on the base 21. The rotatable screen 22 is rotatably connected to the lower plate 1 through two spaced upper plates 2. Each end of the lower plate 1 has a vertically downward bending portion 12. The front end of each bending portion 12 has a mounting portion 13 extending to the outside of the base 21. A rotating shaft 3 is mounted on the mounting portion 13. The two upper plates 2 are correspondingly fitted onto the two rotating shafts 3 and can rotate around the rotating shafts 3.

[0025] The mounting part 13 has two spaced-apart first protrusions 91 and second protrusions 92 on one end near the upper plate 2. When the upper plate 2 is in a vertical 90° position, the first protrusion 91 is in line contact with the upper plate 2. When the upper plate 2 is in a 130° position, the second protrusion 92 is in line contact with the upper plate 2. The areas of the first protrusion 91 and the second protrusion 92 that are in contact with the upper plate 2 are arc-shaped.

[0026] The rotating shaft 3 has a flange 4 located between the lower plate 1 and the upper plate 2. A support plate 5 is rotatably mounted on the rotating shaft 3 and connected to the upper plate 2. One end face of the support plate 5 is in contact with the flange 4. A spring 6 is mounted on the rotating shaft 3 between the other end face of the support plate 5 and the upper plate 2. Several spring pieces 7 are mounted on the rotating shaft 3 on the side of the upper plate 2 opposite to the spring 6 and are pressed and fixed by nuts 8.

[0027] A washer 10 is provided between each end of the spring 6 and the upper plate 2 and the support plate 5.

[0028] The aforementioned support plate 5 includes a main body 51 for connecting with the upper plate 2 and a connecting part 52 perpendicular to the main body 51. One end of the connecting part 52 is fitted onto the rotating shaft 3 and can rotate around the rotating shaft 3.

[0029] In use, the upper plate 2 rotates around the pivot. When it reaches 90°, it is stopped by the first protrusion 9 on the lower plate 1 in the clockwise direction. When the upper plate 2 rotates counterclockwise around the pivot to 130°, it is stopped by the second protrusion, thus completing the entire action.

[0030] When the product is at 90° or 130° and subjected to a strong impact, the upper plate 2 will directly pass the stop point. Afterwards, the product can continue to be used normally simply by adjusting it to the normal working area.

[0031] When using the above-mentioned drop-resistant foldable electronic device, a flange is provided on its rotating shaft between the lower and upper plates. A support plate is rotatably mounted on the rotating shaft and connected to the upper plate. One end face of the support plate is in contact with the flange. A spring is mounted on the rotating shaft between the other end face of the support plate and the upper plate. Several spring pieces are mounted on the rotating shaft on the side of the upper plate opposite to the spring and are fixed by compression with nuts. Through the combined use of the spring and spring pieces, the upper plate can be stably rotated within a certain range. When subjected to impact, the impact can be effectively mitigated, the structure can be protected, and the torque can be kept stable, thereby ensuring the stability of the overall structure during long-term use.

[0032] Furthermore, the mounting section has two spaced-apart first protrusions and second protrusions on the end near the upper plate. When the upper plate is in a vertical 90° position, the first protrusion makes line contact with the upper plate. When the upper plate is in a 130° position, the second protrusion makes line contact with the upper plate. The areas of the first and second protrusions that make contact with the upper plate are arc-shaped, which can achieve a stop at 90° and 130° positions. When the product is at 90° or 130° and is subjected to a strong impact, the upper plate will directly pass over the stop point. Afterwards, the product can continue to be used normally by simply adjusting it to the normal working area, which can reduce the damage to the entire mechanism and reduce the risk of damage to the stop point.

[0033] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
