The present utility model proposes a nib assembly 100.

Referring to fig. 1 and 2, in an embodiment of the present utility model, the nib assembly 100 includes a pen cap 110 and a probe 130; a pen cavity 111 with a cavity opening 111a is arranged in the pen cap 110; the probe 130 is arranged in the pen cavity 111, and the probe 130 is in interference fit with one end of the pen cap 110 away from the cavity opening 111 a; the end of the probe 130 facing away from the cavity opening 111a is provided with a through hole 150, in the riveting process, the gas between the probe 130 and the pen cap 110 is transferred towards the cavity opening 111a through the probe 130, and/or the end of the pen cap 110 facing away from the cavity opening 111a is provided with a through hole 150, in the riveting process, the gas between the probe 130 and the pen cap 110 is directly transferred to the outside of the pen cap 110 through the pen cap 110.

The size of the aperture of the through hole 150 can be adjusted according to the actual situation by those skilled in the art. In general, the smaller the aperture of the through hole 150, the less likely the performance of the nib assembly 100 is affected, but the difficulty of gas evacuation increases accordingly.

Specifically, the cavity opening 111a is disposed at the top of the pen cap 110, the probe 130 is in interference fit with the lower end of the pen cap 110, and the through hole 150 is disposed at the bottom of the probe 130 and/or the bottom of the pen cap 110. The upper end of the pen cap 110 is provided with a connecting section, the connecting section is cylindrical, the side wall of the connecting section is provided with external threads so as to be in threaded connection with other components, the outer diameter of the pen cap 110 is gradually reduced from top to bottom so as to be in a conical structure, the outer wall of the bottom of the pen cap 110 is in a hemispherical or hemispherical-like shape so as to improve the writing experience of a user, the user generally inclines the pen cap 110 to a certain degree when writing, and the hemispherical or hemispherical-like writing end enables the user to incline the pen cap 110 at multiple angles relative to the vertical direction without affecting the writing experience; in another aspect, the entire outer wall surface of the lower end of the pen cap 110 is a conical surface or a conical-like surface, which is convenient to hold, and the outer wall surface of the bottom of the pen cap 110 is a hemispherical surface or a hemispherical-like surface, which can avoid the risk of scratching the human body by the edges of the corners.

According to the technical scheme, through holes 150 are formed in the bottom of the probe 130 and/or the bottom of the pen cap 110, so that the situation that riveting is not carried out in place between the probe 130 and the pen nozzle due to gas backlog in the riveting assembly process is avoided. In the process of riveting and assembling the probe 130 and the pen cap 110, the riveting jig is used to press the probe 130 into the bottom of the pen cap 110, in this process, the gas clamped between the bottom of the probe 130 and the bottom of the pen cap 110 can be led out through the through hole 150, so that the situation that the probe 130 cannot be riveted in place due to gas backlog between the probe 130 and the pen cap 110 is avoided, and the product yield is improved.

In the nib assembly 100 of the present utility model, the through hole 150 may be formed at the bottom of the probe 130 or at the bottom of the cap 110, and preferably, the through hole 150 is formed at the bottom of the probe 130. Generally, the probe 130 is made of a hardware material, the cap 110 is made of a plastic material, and since the hole diameter of the through hole 150 is very small (possibly even smaller than 0.1 mm), it is very difficult to make the hole in the cap 110 made of a plastic material, and on the other hand, the opening of the through hole 150 on the cap 110 also affects the aesthetic appearance of the entire nib assembly 100.

Referring to fig. 3, in an embodiment, the probe 130 is a spring 135 probe 130, the probe 130 includes a needle tube 131 and a needle 133, one end of the needle 133 is disposed in the needle tube 131 and is elastically connected to the needle tube 131, the needle 133 can move along the axial direction of the needle tube 131, the needle tube 131 is in interference fit with the pen cap 110, the through hole 150 is disposed at an end of the needle tube 131 away from the needle tube 133, and the through hole 150 is in communication with the interior of the needle tube 131. During the riveting process, the gas between the probe 130 and the pen cap 110 is transferred to the inside of the needle tube 131 through the through hole 150, and then transferred to the outside of the needle tube 131 through the gap between the needle tube 131 and the needle 133.

The probe 130 further comprises a spring 135, the spring 135 is disposed in the needle tube 131 and is clamped between the needle tube 131 and the needle head 133, the upper end and the lower end of the spring 135 are respectively connected with the needle tube 131 and the needle head 133, and the spring 135 stretches along the axial direction of the needle tube 131.

In general, the larger the contact area between the bottom and side of the needle tube 131 and the lower end (writing part) of the pen cap 110, the more advantageous the signal transmission between the probe 130 and the writing instrument. In an embodiment, the shape of the outer wall of the lower end of the needle tube 131 is consistent with the shape of the inner wall of the lower end of the pen cap 110, and the outer wall of the lower end of the needle tube 131 is attached to the inner wall of the lower end of the pen cap 110, so that when different parts of the lower end (writing part) of the pen cap 110 are used for contacting writing equipment during writing, the probe 130 outputs signals.

In the above embodiment, more specifically, the side wall of the lower end of the needle tube 131 is in interference fit with the pen cap 110, the outer bottom wall and the outer side wall of the lower end of the needle tube 131 are correspondingly attached to the inner bottom wall and the inner side wall of the lower end of the pen cap 110, and the through hole 150 is provided at the bottom of the needle tube 131.

In order to reduce the riveting difficulty, the needle tube 131 has a structure with a narrow bottom and a wide top, in an embodiment, a side surface of the needle tube 131 is cylindrical or cylindrical-like, a bottom surface of the needle tube 131 is hemispherical or hemispherical-like, and a side portion of the needle tube 131 is smoothly connected with a bottom portion. The shape of the needle tube 131 has various advantages, on one hand, as described above, the difficulty of riveting the probe 130 into the pen cap 110 can be reduced, and on the other hand, the shape of the bottom of the needle tube 131 is consistent with the shape of the inner and outer walls of the bottom of the pen cap 110, so that the signals output by the pen cap 110 when writing at different inclination angles have consistency, and the stability of signal transmission when writing is improved.

Further, in an embodiment, the through hole 150 is disposed in the middle of the bottom wall of the needle tube 131. The through hole 150 is provided in the middle of the bottom wall of the needle tube 131, so that it is possible to avoid the deflection of the probe 130 toward one side during riveting to affect the product function as much as possible; in addition, the exhaust efficiency of the through hole 150 can be improved.

To facilitate riveting the probe 130 into the bottom of the pen cap 110, in one embodiment, a pushing portion 1311 is protruding from the side wall of the needle tube 131 near the end of the cavity 111a (i.e., the upper end of the needle tube 131). In the riveting process, the riveting jig pushes the probe 130 towards the bottom of the pen cap 110 through the pushing portion 1311.

The utility model also provides an intelligent pen, which comprises a pen point assembly 100, wherein the specific structure of the pen point assembly 100 refers to the embodiment, and as the intelligent pen adopts all the technical schemes of all the embodiments, the intelligent pen at least has all the beneficial effects brought by the technical schemes of the embodiments, and the detailed description is omitted.
