Description

Technical Field

[0001] This utility model relates to the field of electromagnetic pen technology, specifically to an electromagnetic pen positioning accuracy optimization device for an electromagnetic screen display module. Background Technology

[0002] An electromagnetic pen is a handwriting input device based on electromagnetic induction technology. It achieves high-precision positioning and pressure-sensitive writing by working with a screen that has a built-in electromagnetic induction layer.

[0003] However, most existing electromagnetic pens are composed of components encapsulated in a shell. This means that the entire pen relies solely on a single shell for protection. When dropped, the impact directly affects the shell and vibrates the internal components, making it difficult to effectively protect the pen and easily leading to damage. Furthermore, the shells of electromagnetic pens are mostly made of plastic, which allows electromagnetic signals to penetrate the plastic shell and interfere with the internal components under external electromagnetic interference, thus affecting the accuracy of the pen's contact positioning and impacting its usability.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed an electromagnetic pen positioning accuracy optimization device for electromagnetic screen display modules. Utility Model Content

[0005] The purpose of this invention is to provide an electromagnetic pen positioning accuracy optimization device for an electromagnetic screen display module, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic pen positioning accuracy optimization device for an electromagnetic screen display module, comprising a sleeve, with protrusions uniformly distributed and fixedly connected to the outer surface of the sleeve, an electromagnetic protective plate fixedly connected to the inner wall of the sleeve, an end sleeve provided on the lower side of the sleeve, a threaded ring fixedly connected to the upper surface of the end sleeve, a through opening at the bottom end of the end sleeve, a rotating head rotatably connected to the upper surface of the sleeve via a damping rotating ring, and the same adjusting clamping mechanism provided on the lower surface of the rotating head and the upper surface of the inner surface of the sleeve.

[0007] Preferably, the protrusion is a rubber hemisphere made of soft rubber, and the end sleeve is threadedly connected to the sleeve via a threaded ring.

[0008] Preferably, the adjusting clamping mechanism includes a bidirectional lead screw rotatably connected to the upper side of the inner surface of the sleeve, and a top plate is fixedly connected to the upper side of the inner surface of the sleeve below the bidirectional lead screw. The top plate has through cavities on both the left and right sides of its surface.

[0009] Preferably, the adjusting clamping mechanism further includes a driven bevel gear fixedly connected to the right side of the center of the bidirectional lead screw surface, and a driving bevel gear is meshed on the left side of the upper surface of the driven bevel gear, and the upper surface of the driving bevel gear is fixedly connected to the center of the lower surface of the rotating head.

[0010] Preferably, the adjusting clamping mechanism further includes connecting rods threaded to both the left and right sides of the bidirectional lead screw surface, and the lower end of the connecting rod is slidably fitted and fixedly connected to a clamping plate through the cavity, and the clamping plate is set as a semi-circular arc plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a sleeve, a protrusion, an electromagnetic protective plate, an end sleeve, a threaded ring, and a through-hole, allows the electromagnetic pen to be placed inside the sleeve. The end sleeve, connected to the sleeve by the threaded ring, completely encloses the electromagnetic pen, and the contact point of the electromagnetic pen tip can protrude through the through-hole without affecting its use. In the event of a drop, the sleeve and end sleeve can make contact with the ground first, preventing the impact from directly affecting the electromagnetic pen, thus effectively protecting it. At the same time, the protrusion, in contact with the ground, uses its own rubber elasticity to cushion the impact, reducing drop damage and further enhancing the protection of the electromagnetic pen. The electromagnetic protective plate in the entire device is wrapped around the sleeve, which can block external electromagnetic fields from interfering with the signal of the internal electromagnetic pen, thereby significantly improving the positioning accuracy of the electromagnetic pen and preventing contact point positioning from shifting.

[0013] 2. This utility model, through the arrangement of a screw head, adjusting clamping mechanism, bidirectional lead screw, top plate, through cavity, driven bevel gear, driving bevel gear, connecting rod, and clamping plate, limits the maximum insertion depth of the electromagnetic pen when it is inserted into the sleeve. Then, by screwing the screw head, the driving bevel gear meshes with the driven bevel gear and rotates. The bidirectional lead screw will follow the driven bevel gear and rotate. Under the limitation of the connecting rod by the inner wall of the through cavity, the connecting rod will only be subjected to the thread force to move in the opposite direction, thereby driving the clamping plate to move in the opposite direction and clamping and fixing the tip of the electromagnetic pen. This improves the stability of the electromagnetic pen placed inside the sleeve and prevents the electromagnetic pen from shaking and being damaged. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-3 As shown, an electromagnetic pen positioning accuracy optimization device for an electromagnetic screen display module includes a sleeve 1. The outer surface of the sleeve 1 is uniformly distributed and fixedly connected with protrusions 2. The inner wall of the sleeve 1 is fixedly connected with an electromagnetic protective plate 3. An end sleeve 4 is provided on the lower side of the sleeve 1. A threaded ring 5 is fixedly connected to the upper surface of the end sleeve 4. A through-hole 6 is opened at the bottom end of the end sleeve 4. A rotating head 7 is rotatably connected to the upper surface of the sleeve 1 via a damping rotating ring. The same adjustment and clamping mechanism 8 is provided on the lower surface of the rotating head 7 and the upper surface of the inner surface of the sleeve 1.

[0020] The protrusion 2 is a rubber hemisphere made of soft rubber, and the end sleeve 4 is threadedly connected to the sleeve 1 through the threaded ring 5.

[0021] By adopting the above technical solution, the electromagnetic pen is placed inside the sleeve 1. After the end sleeve 4 is connected to the sleeve 1 by the threaded ring 5, it completely covers the electromagnetic pen. The sleeve 1 and the end sleeve 4 can make contact with the ground first, and the collision will not directly affect the electromagnetic pen.

[0022] The contact point at the tip of the electromagnetic pen can protrude through the port 6 without affecting its use;

[0023] When the protrusion 2 contacts the ground, it will use its own rubber elasticity to cushion the impact, reduce damage from falls, and further enhance the protection of the electromagnetic pen.

[0024] The electromagnetic shielding plate 3 is wrapped around the sleeve 1 in a ring-like manner, thereby blocking the external electromagnetic field from interfering with the signal of the internal electromagnetic pen.

[0025] Furthermore, the adjusting clamping mechanism 8 includes a bidirectional lead screw 801 rotatably connected to the upper side of the inner surface of the sleeve 1, and a top plate 802 is fixedly connected to the upper side of the inner surface of the sleeve 1 below the bidirectional lead screw 801. A through cavity 803 is opened on both the left and right sides of the surface of the top plate 802.

[0026] Furthermore, the adjusting clamping mechanism 8 also includes a driven bevel gear 804 fixedly connected to the right side of the center of the surface of the bidirectional lead screw 801. A driving bevel gear 805 is meshed on the left side of the upper surface of the driven bevel gear 804, and the upper surface of the driving bevel gear 805 is fixedly connected to the center of the lower surface of the rotating head 7.

[0027] Furthermore, the adjusting clamping mechanism 8 also includes a connecting rod 806 threaded to both the left and right sides of the surface of the bidirectional lead screw 801, and the lower end of the connecting rod 806 is slidably attached to the through cavity 803 and fixedly connected to a clamping plate 807, and the clamping plate 807 is set as a semi-circular arc plate.

[0028] By adopting the above technical solution, when the electromagnetic pen is inserted into the sleeve 1, the top plate 802 limits the maximum insertion depth of the electromagnetic pen. Then, by turning the screw head 7, the active bevel gear 805 is driven to mesh with the driven bevel gear 804 and rotate. The bidirectional screw 801 will rotate with the driven bevel gear 804. Under the limitation of the connecting rod 806 by the inner wall of the cavity 803, the connecting rod 806 will only be subjected to the thread force to move in the opposite direction, thereby driving the clamping plate 807 to move in the opposite direction and clamping and fixing the tip of the electromagnetic pen.

[0029] Working Principle: When using the electromagnetic pen positioning accuracy optimization device of this electromagnetic screen display module, firstly, the electromagnetic pen is inserted into the sleeve 1. The top plate 802 limits the maximum insertion depth of the electromagnetic pen. Then, by turning the screw head 7, the active bevel gear 805 meshes with the driven bevel gear 804 to rotate. The bidirectional lead screw 801 will rotate with the driven bevel gear 804. Under the limitation of the connecting rod 806 by the inner wall of the cavity 803, the connecting rod 806 will only be subjected to the thread force to move in opposite directions, thereby driving the clamping plate 807 to move in opposite directions and clamp and fix the tip of the electromagnetic pen. After the electromagnetic pen is fixed, the end sleeve 4 is connected to the sleeve 1 by the threaded ring 5, and then... The electromagnetic pen is completely enclosed, and the contact point of the electromagnetic pen tip can extend through the opening 6. The electromagnetic protection plate 3 in the device is wrapped around the sleeve 1, which can block the external electromagnetic field from interfering with the signal of the internal electromagnetic pen, thereby greatly improving the positioning accuracy of the electromagnetic pen. In the event of a drop, the sleeve 1 and the end sleeve 4 can make contact with the ground first, and the impact will not directly affect the electromagnetic pen, thus effectively protecting the electromagnetic pen. At the same time, the protrusion 2, when in contact with the ground, will use its own rubber elasticity to cushion the impact and reduce the damage from the drop. This is the working principle of the electromagnetic pen positioning accuracy optimization device of the electromagnetic screen display module.
