The invention provides a pen point waterproof structure, which is suitable for an electronic pen capable of realizing touch control or writing functions on an electronic screen, such as a touch control pen, also called a capacitance pen or an intelligent pen, and generally, the touch control pen comprises a pen shell 100, a pen core 200 and an internal circuit component.
In one embodiment, the waterproof structure for the pen tip according to the present invention includes a pen case 100, a pen core 200, and an elastic waterproof member 300.
A through hole is provided at one end of the case 100, and the cartridge 200 is provided in the case 100, the cartridge 200 having a nib section 210 protruding from the case 100 through the through hole.
The pen shell 100 is not limited in style, and is generally in a pen shape common in daily life and used for holding; the pen core 200 is also not limited in style, and is usually connected to the pen case 100, and may be inserted or connected in another way, and has a pen tip section 210 extending outside the case for writing, drawing or touching on the capacitive screen.
The common connection mode of the pen core 200 and the pen shell 100 is insertion connection, and the insertion connection mode is adopted for connection, so that the waterproofness and the dustproofness are generally poor, most of the pen shells 100 of the touch control pen adopt the integrated pen shell 100 at present, and the only place which can be invaded by water or dust is the pen point, namely the insertion connection position of the pen core 200 and the pen shell 100.
According to the invention, the touch pen is sealed by the elastic waterproof piece 300, the elastic waterproof piece 300 is provided with the first connecting part 310 and the second connecting part 330, the first connecting part 310 is hermetically connected to the pen point section 210 in a sealing manner, the second connecting part 330 is hermetically connected to the pen shell 100 in a sealing manner, and a gap at the insertion position of the pen core 200 and the pen shell 100 is hermetically wrapped, so that the waterproof reliability is improved, and various sealing and sleeving manners, such as injection molding, are adopted.
In practical application, a touch pen is generally required to be capable of writing with different thicknesses according to the requirements of a user, and generally, the larger the force for writing the touch pen is, the thicker the strokes displayed on a capacitive screen is; refill 200 has relative both ends, the nib of one end for being used for writing, the other end meets with the signal probe 400 of placing the casing in, signal probe 400 meets with pressure sensor 500, pressure sensor 500 can sense the change of the user dynamics of writing, thereby change the thickness of handwriting according to the change of the user dynamics of writing, and then reach excellent effect and experience, for making pressure sensor 500 can normally work, need refill 200 can carry out the flexible of certain degree along the axial of through-hole.
The waterproof piece 300 of elasticity that this embodiment adopted is soft material, and is changeed in general stereoplasm material and produces deformation relatively, can satisfy refill 200 along the axial fore-and-aft concertina movement of through-hole, and waterproof piece 300 of elasticity can adopt liquid silica gel, and liquid silica gel has excellent tear resistance, resilience, anti-yellowing nature, heat stability and ageing resistance, and for other most materials, its is safer environmental protection. Of course, in other embodiments, the material of the elastic waterproof member 300 may also be elastic plastic (such as TPE, TPR, TPU, etc.) or other materials.
In the daily writing and drawing touch screen, the direction of force applied to the pen point is not single, the pen point can do front and back telescopic movement along the axial direction of the through hole of the pen shell 100 under the action of external force, and can generate small left and right shaking and deformation under the action of external force, so that the gap at the insertion joint of the pen core 200 and the shell can be increased, the risk of liquid intrusion can be increased if the pen core 200 is carelessly contacted with liquid at the moment, furthermore, the pen core 200 inserted in the pen shell 100 can continuously collide with the inner wall of the pen shell 100 in the using process, certain abrasion can be generated along with the time, the gap at the insertion joint of the pen core 200 and the pen shell 100 can be further increased, and the risk of liquid and dust intrusion is increased; the elastic material can rock along with the pen core 200 due to the characteristics of the elastic material, so that the pen point is ensured to be in a sealed state at any time, and the reliability of water resistance and dust resistance is greatly improved.
Compared with the conventional waterproof scheme, the elastic waterproof piece 300 is directly adopted to seal the gap at the joint of the pen core 200 and the pen shell 100, the elastic waterproof piece 300 is extruded when the pen core 200 is stressed to do telescopic motion along the axial direction of the through hole of the pen shell 100 in the writing process, the waterproof and dustproof effects are further achieved, when the pen core 200 is stressed to shake left and right, the elastic waterproof piece 300 also shakes left and right, liquid or dust is difficult to enter the pen shell 100, and the waterproof and dustproof performance of the touch pen is greatly improved.
Here, the front and rear directions refer to an axial direction of the through hole of the pen case 100, and the left and right directions refer to directions forming an angle with the axial direction of the through hole of the pen case 100, not fixed two directions.
