Detailed Description
It should be noted that, without conflict, the embodiments and features of the embodiments in the present application may be combined with each other, and the present utility model will be further described in detail with reference to the drawings and the specific embodiments.
In the embodiment of the present utility model, if there is a directional indication (such as up, down, left, right, front, and rear … …) only for explaining the relative positional relationship, movement condition, etc. between the components in a specific posture (as shown in the drawings), if the specific posture is changed, the directional indication is correspondingly changed.
In addition, the description of "first," "second," etc. in this disclosure is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implying an indication of the number of features being indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.
Referring to fig. 1 to 6, the pressure-sensitive electronic pen with overpressure protection according to an embodiment of the present utility model includes a pen body, a pressure sensor, a pen point core rod, a pressure-bearing block, a pressure rod, and an elastic member.
The pressure-bearing block is fixedly arranged in the pen body, the pressure rod is correspondingly arranged in front of the pressure sensor, two ends of the elastic piece are respectively connected with the pressure rod and the nib core rod, the tail end of the nib core rod is provided with a limiting part, and the limiting part and the pressure-bearing block are separated by a preset distance. The preset distance is small, so that a small gap is reserved between the limiting part and the pressure bearing block. Preferably, a certain gap is also arranged between the pressing rod and the pressure bearing block.
When writing, the writing pressure received by the nib core rod is transmitted to the elastic piece, and the elastic piece is transmitted to the pressure sensor through the pressing rod. The elastic piece can not be compressed and deformed during normal writing. When the writing pressure is too high, the elastic piece is compressed, the limiting part of the nib core rod is contacted with the front end of the pressure-bearing block, and the nib core rod is blocked and limited by the pressure-bearing block, so that the pressure sensor is prevented from being crushed by the pressure-bearing block; when the nib core rod is loosened, the elastic piece is restored to the original state, and the writing pressure is continuously transmitted.
As one implementation mode, a guide hole is arranged in the pressure-bearing block, and a guide post correspondingly positioned in the guide hole is arranged at the tail end of the nib core rod. The guide hole is matched with the guide post (the guide post is inserted from the front end of the guide hole), so that the axial upward movement of the nib core rod is limited, and the nib core rod can be prevented from shaking during writing.
As an implementation mode, the front end of the pressing rod is provided with a limiting column (the limiting column is inserted from the rear end of the guide hole) which is correspondingly positioned in the guide hole, the limiting column is matched with the guide column, limiting is carried out for the axial upward movement of the pressing rod, the pressing rod can be prevented from shaking during writing, the accuracy of the pressure transmission of the pressing rod is improved, and the pressure sensing precision is improved.
As an embodiment, the pressure-sensitive electronic pen with overpressure protection further comprises a pre-compression spring, wherein the pre-compression spring acts on the nib core rod to apply a backward pre-compression force to the nib core rod. The pre-pressing spring enables the pressing rod to be in continuous contact with the pressure sensor, the sensitivity of pressure sensing is improved, meanwhile, the nib core rod is pre-pressed, the situation that the nib core rod is loose and collapses before or during writing is prevented, and the writing hand feeling is improved.
