Description

Writing pad

Technical Field

The utility model relates to a handwriting pad.

Background

Writing pads are a common office product and are commonly used for drawing.

The handwriting film and the PCB of the traditional handwriting board are usually arranged at intervals, so that the screen occupation ratio of the handwriting board is small, and the use experience is not good.

SUMMERY OF THE UTILITY MODEL

Based on this, it is necessary to provide a handwriting board with a high screen occupation ratio.

A handwriting board comprises a bottom board shell, a PCB, a handwriting film and an upper frame;

the bottom plate shell and the upper frame enclose an accommodating cavity, and the PCB and the handwriting film are arranged in the accommodating cavity;

the bottom plate shell is provided with a mounting groove matched with the PCB, the PCB is arranged in the mounting groove, and the handwriting film is stacked on the PCB.

The PCB board setting of this kind of handwriting pad is in the mounting groove to can range upon range of the handwriting film on the PCB board, the front of handwriting pad only has the frame except handwriting film, for the handwriting pad that traditional handwriting film and PCB board separated the setting, the screen of this kind of handwriting pad accounts for than higher, uses and experiences better.

Drawings

Fig. 2 is an exploded view of the writing tablet shown in fig. 1.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.

The handwriting board of one embodiment as shown in fig. 1 and 2 includes a bottom casing 10, a PCB board 20, a handwriting film 30, and an upper frame 40.

The bottom plate shell 10 and the upper frame 40 enclose a containing cavity, and the PCB board 20 and the handwriting film 30 are both arranged in the containing cavity.

The bottom plate shell 10 is provided with a mounting groove 12 matched with the PCB 20, the PCB 20 is arranged in the mounting groove 12, and the handwriting film 30 is laminated on the PCB 20.

The PCB 20 of the handwriting board is arranged in the installation groove 12, so that the handwriting film 30 can be stacked on the PCB 20, the front surface of the handwriting board is only provided with a frame except the handwriting film 30, and compared with the handwriting board which is arranged between the traditional handwriting film and the PCB at intervals, the handwriting board has the advantages that the screen occupation ratio is high, and the use experience is good.

Referring to the drawings, in the present embodiment, a platform 14 matched with a handwriting film 30 is provided on a base plate housing 10, an area of the platform 14 is recessed to form a mounting groove 12, and the handwriting film 30 is provided on the platform 14, so that the handwriting film 30 is laminated on a PCB 20.

Specifically, in conjunction with the figures, the edges of the platform 14 and the base housing 10 form a recess in which are disposed a plurality of mounting structures by which the upper rim 40 and the base housing 10 are mounted together.

Preferably, in this embodiment, the mounting slot 12 is located at an edge of the platform 14. This arrangement may facilitate electrical connection between PCB board 20 and writing membrane 30.

Referring to the drawings, in the present embodiment, the electronic components on the PCB 20 are disposed on the front or side of the PCB 20, and when the PCB 20 is disposed in the mounting groove 12, the front of the PCB 20 is opposite to the bottom of the mounting groove 12. Such an arrangement makes it possible to prevent the elements from coming into contact with the writing film 30 when the writing film 30 is laminated on the PCB, thereby causing interference with each other.

Specifically, the back surface of the PCB board 20 is a flat surface. Specifically, in the present application, the rear surface of the PCB board 20 is not provided with any element.

Referring to the drawings, in the present embodiment, the handwriting film 30 and the PCB 20 are electrically connected through an FPC board (flexible circuit board, not shown). Because the PCB 20 and the handwriting film 30 are arranged in a laminated manner, the FPC board is adopted to realize high stability of electric connection between the PCB and the handwriting film, and the lamination of the PCB and the handwriting film is not influenced.

Specifically, in the present embodiment, the chassis housing 10 has a rectangular plate shape, the PCB board 20 has an elongated shape, and the longitudinal direction of the PCB board 20 is parallel to one side of the chassis housing 10.

Specifically, in the present embodiment, the bottom plate case 10 is further provided with a screen clearing key 16. After the screen-clearing key 16 is pressed, the pattern drawn on the handwriting film 30 can be erased completely.

Preferably, in other embodiments, the writing pad further comprises a stylus. Specifically, a first magnetic member is disposed on one side of the bottom plate housing 10, a second magnetic member is disposed on the stylus, and the first magnetic member and the second magnetic member are magnetically attracted to be connected, so that the stylus is magnetically attracted to the bottom plate housing 10.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
