DETAILED DESCRIPTION

[0018] The utility model of this application is further described in detail below with reference to the accompanying drawings and specific embodiments. In order to clearly and completely describe the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content recorded in this application without creative work are all within the scope of protection of this utility model.

[0019] In the following embodiments, it should be noted that the terms "up", "down", "left", "right", "inside", "outside", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of clearly describing the present embodiment, and do not indicate or imply that the device or element referred to must have a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0020] like Figure 1-4 As shown, the specific embodiment described in the present invention is a periscope smart pen, whose structure includes a pen holder 1, an image acquisition module 2, a second PCB board 10, a pen barrel 3, a pressure sensing module 5, a pen refill 6, a control element, etc., wherein the image acquisition module 2 includes an optical sensor 22 on a first PCB board 21 and a periscope lens module 23.

[0021] Specifically, a first PCB board 21 is provided on the pen holder 1, and an optical sensor 22 is mounted parallel to the first PCB board 21. This parallel installation method allows the optical sensor 22 to have a larger size without being restricted by factors such as packaging and wiring, and there is no need to reserve wiring positions on the left and right positions. A collection port 4 is provided at the bottom of the pen holder 1, and a periscope lens module 23 is embedded in the collection port 4. The lens module can guide light to the optical sensor 22. The lens module is composed of a first lens 231 and a reflector 232. The reflector 232 is at a 45° angle to the PCB board, and the axis of the first lens 231 is parallel to the first PCB board 21. This design ensures that after the light is reflected by the reflector 232, it can be vertically incident on the first lens 231, and then focused by the first lens 231 and projected onto the optical sensor 22.

[0022] A pressure-sensing module 5 is installed within the pen holder 1, and a pen refill 6 is nested within the pen holder 1. The pen refill 6 can slide up and down within the pen holder 1. When the pen refill 6 slides, it moves the first magnetic member 51 in the pressure-sensing module 5. The first magnetic member 51 and the second magnetic member 52 magnetically attract each other and compress the pressure-sensing element 57, triggering the pressure-sensing element 57 to generate a pressure signal. This pressure signal is transmitted to the control unit for processing.

[0023] Specifically, the pressure sensing module 5 also includes a connecting frame 53, which can be snap-connected to the pen core 6. The connecting frame 53 is respectively provided with a receiving cavity 54 for accommodating the first magnetic part 51 and a receiving groove 55 for accommodating the pressure sensing element 57; the pen holder 1 is provided with a limiting groove 56 that is compatible with the second magnetic part 52.

[0024] A control element is provided on the first PCB board 21, and the optical sensor 22 is electrically connected to the control element. The control element is capable of receiving and processing data from the optical sensor 22, and outputting corresponding operating instructions based on this data. For example, the optical sensor 22 can be used to capture the contents of a paper and detect handwriting or drawing. When the optical sensor 22 detects handwriting, the control element can digitize the handwriting and synchronize it to a digital device; a control unit is provided on the second PCB board 10, and the pressure sensing module 5 is electrically connected to the control unit. The control unit is capable of receiving and processing data from the pressure sensing module 5, and outputting corresponding operating instructions based on this data. For example, when the pressure sensing module 5 detects the sliding of the pen core 6, the control element can identify it as a writing operation and activate the corresponding function.

[0025] Furthermore, the end of the pen holder 1 is connected to a cap 8 equipped with charging contacts for charging the smart pen. The pen barrel 3 is equipped with a pen cap 9, which is also equipped with a ring magnet 7. A Hall effect switch is located on the PCB and is electrically connected to the control components. When the pen is inserted or removed from the pen cap 9, the relative position of the ring magnet 7 on the pen cap 9 and the Hall effect switch changes, enabling power on and off control. This design not only facilitates user experience but also enhances the smart pen's intelligence.

[0026] The periscope-style smart pen provided by this utility model utilizes a parallel-mounted optical sensor 22 and a periscope lens module 23, addressing the limited size and poor mounting stability of the optical sensor 22 in existing smart pens. Furthermore, the design of the pressure-sensing module 5 enables precise detection of the movement of the refill 6, improving the smart pen's handwriting recognition accuracy. Furthermore, the addition of charging contacts and power-on / off control further enhances the smart pen's practicality and intelligence.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements and improvements made to the above embodiments based on the technical essence of the present invention should be included in the scope of protection of the technical solution of the present invention.
