[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-7 As shown, a mobile phone protective case with a drawing board function includes a leather jacket 1, a bottom shell 2 and an upper cover 4 are fixedly connected to the leather jacket 1, a mobile phone body 3 is clamped in the bottom shell 2, an antenna board 5 is installed in the upper cover 4, a handwriting screen 6 is installed on the antenna board 5, the upper cover 4 is covered on the bottom shell 2, a mounting structure 7 is installed on the leather jacket 1, and the mounting structure 7 includes a pen cover 701, a pen cover 701 is fixedly connected to the leather jacket 1, an electromagnetic pen 13 is slidably connected to the pen cover 701, and a spring 7 is fixedly connected to the end of the pen cover 701. 02, a support plate 703 is fixedly connected to the spring 702, and the support plate 703 is slidably connected to the inner wall of the pen cover 701, and the support plate 703 and the electromagnetic pen 13 are in conflict with each other at one end facing the spring 702, and a fixed structure 8 is installed on the leather jacket 1; the upper cover 4 of the mobile phone protective case has an antenna board 5 that can sense electromagnetic handwriting signals, and is equipped with a handwriting screen 6, which has the function of a drawing board. The upper cover 4 usually protects the screen of the mobile phone body 3. When the upper cover 4 is opened, the electromagnetic pen 13 included in the case can be used to write and draw, thereby making the functions of the mobile phone protective case diversified and more practical.

[0024] As a technical optimization solution of the present invention, six first protrusions 9 are fixedly connected to the bottom shell 2, and six second protrusions 10 are fixedly connected to the upper cover 4. The first protrusions 9 are engaged with the corresponding second protrusions 10. The cross-section of the first protrusions 9 is a "convex"-shaped structure, and the cross-section of the second protrusions 10 is a "concave"-shaped structure. When the mobile phone body 3 is no longer in use, the upper cover 4 is covered on the bottom shell 2. At this time, the first protrusions 9 on the edge of the upper cover 4 are engaged with the second protrusions 10. At the same time, the depth of the groove on the second protrusion 10 is less than the overall height of the first protrusion 9. When the first protrusions 9 are engaged with the second protrusions 10, a gap is retained between the upper cover 4 and the bottom shell 2 to avoid complete contact and friction between the screen of the mobile phone body 3 and the handwriting screen 6, thereby preventing external fine particles from falling between the two and causing scratches or damage to the screens of both.

[0025] As a technical optimization solution of the present utility model, the end of the pen cover 701 facing away from the spring 702 is fixedly connected to a connecting block 704, and a rotating shaft 705 is rotatably connected to the connecting block 704. The rotating shaft 705 is fixedly connected to a cover 706, and the cover 706 and the end of the electromagnetic pen 13 facing away from the spring 702 are in contact with each other; the cover 706 contacts the electromagnetic pen 13, so that the electromagnetic pen 13 is stored in the pen cover 701, thereby protecting the electromagnetic pen 13.

[0026] As a technical optimization solution of the present invention, a torsion spring 707 is sleeved on the rotating shaft 705, one end of the torsion spring 707 is fixedly connected to the cover 706, and the other end of the torsion spring 707 is fixedly connected to the connecting block 704, the torsion force of the torsion spring 707 is greater than the elastic force of the spring 702, and a pull plate 708 is fixedly connected to the cover 706; the torsion spring 707 drives the cover 706 to always block the entrance of the pen cover 701, and the torsion force of the torsion spring 707 is greater than the elastic force of the spring 702, so that the cover 706 can stably resist the electromagnetic pen 13, thereby preventing the electromagnetic pen 13 from slipping out of the pen cover 701 under the action of the spring 702.

[0027] As a technical optimization solution of the present invention, three connecting sleeves 11 are fixedly connected to the leather jacket 1, and a data cable 12 is locked in the connecting sleeve 11; it is convenient to carry the data cable 12, and the connecting sleeve 11 is made of elastic material, and the setting of the connecting sleeve 11 is convenient for storing the data cable 12.

[0028] As a technical optimization solution of the present invention, the fixing structure 8 includes a fixing belt 801, one side of the leather jacket 1 is fixedly connected to the fixing belt 801, a magnet 802 is installed in the fixing belt 801, the other side of the leather jacket 1 is fixedly connected to an iron sheet 803, and the magnet 802 is magnetically connected to the iron sheet 803; through the magnetic attraction between the magnet 802 and the iron sheet 803, the upper cover 4 and the bottom shell 2 remain covered, thereby protecting the mobile phone body 3.

[0029] When the present invention is in use, first lift the fixing belt 801 upwards so that the magnet 802 and the iron sheet 803 are no longer magnetically connected, then open the upper cover 4, so that the leather jacket 1 is unfolded and laid flat, thereby facilitating writing and drawing on the handwriting screen 6, and then lift the pull plate 708, which drives the cover plate 706 to move in the direction away from the electromagnetic pen 13, and the cover plate 706 drives the rotating shaft 705 to rotate, so that the cover plate 706 no longer conflicts with the electromagnetic pen 13, and when the cover plate 706 does not conflict with the electromagnetic pen 13, the spring 702 resets, driving the support plate 703 to slide in the direction of the cover plate 706, and the support plate 703 is rotated. 03 drives the electromagnetic pen 13 to slide, so that the end of the electromagnetic pen 13 slides to the outside of the pen cover 701, which makes it easy to take out the electromagnetic pen 13, and then use the electromagnetic pen 13 to write and draw on the handwriting screen 6, thereby making the functions of the mobile phone protective cover more diversified and more practical, making people's daily use more convenient and flexible; when it is necessary to store the electromagnetic pen 13, the cover 706 is opened by pulling the plate 708, so that the cover 706 no longer blocks the entrance of the pen cover 701, and at this time the torsion spring 707 is twisted and stored, and the electromagnetic pen 13 is inserted into the pen cover 701, and then the cover 70 is released. 6. The torsion spring 707 is reset, and the cover plate 706 is driven to rotate toward the electromagnetic pen 13 through the rotating shaft 705 until the cover plate 706 contacts the electromagnetic pen 13, causing the electromagnetic pen 13 to slide into the pen cover 701. The electromagnetic pen 13 contacts the support plate 703 and slides. The support plate 703 drives the spring 702 to contract, so that the electromagnetic pen 13 is stored in the pen cover 701, forming a protection for the electromagnetic pen 13, preventing the electromagnetic pen 13 from slipping off the mobile phone protective cover and causing damage or loss. The torsion force of the torsion spring 707 is greater than the elastic force of the spring 702, so that the cover plate 706 can stably contact the electromagnetic pen 1 3, preventing the electromagnetic pen 13 from sliding out of the pen cover 701 under the action of the spring 702; when the mobile phone body 3 is no longer in use, the upper cover 4 is closed on the bottom shell 2. At this time, the first protrusion 9 on the edge of the upper cover 4 is engaged with the second protrusion 10, and the depth of the groove on the second protrusion 10 is less than the overall height of the first protrusion 9. When the first protrusion 9 is engaged with the second protrusion 10, a gap is retained between the upper cover 4 and the bottom shell 2, avoiding complete contact and friction between the screen of the mobile phone body 3 and the handwriting screen 6, thereby preventing external fine particles from falling between the two and causing scratches or damage to the screens of both.
