Description

Technical Field

[0001] The present invention relates to the technical field of scanning pens, and in particular to a vertical scanning pen. Background Art

[0002] A scanning pen is a handheld electronic device. Users can scan and enter text or images by holding the scanning pen. Through the built-in optical character recognition (OCR) module, text can be recognized, stored and edited. It is widely used in scenarios such as student learning and travel translation.

[0003] Currently, scanning pens that support intelligent recognition and translation are very popular among users. If you encounter a word you don’t understand, you only need to scan it to know the meaning, which is very helpful for learning and communication. However, most scanning pens on the market currently rely on pressing one end of the stylus tip to trigger recognition. Each recognition requires dragging the stylus tip to scan, and the scanning area changes with the dragging position, which is not conducive to global scanning (for example, recognizing a whole page of a book). Some scanning pens with global scanning functions are still not very convenient to operate when performing global scanning. For example, they cannot be conveniently placed on the desktop, which reduces the user experience.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application.

The magnet plug is inserted into the air intake channel to close the air intake channel, or withdrawn from the air intake channel to open the air intake channel. The electromagnet is arranged corresponding to the magnet plug, and the electromagnet switches polarity depending on a given current.

[0015] Furthermore, a limiting structure is arranged on the air inlet passage, and the limiting structure is used to prevent the magnet plug from completely moving out of the air inlet passage.

[0016] Furthermore, the electromagnet generates a repulsive force with the magnet plug in a default state, so that the magnet plug is kept in the air intake passage.

[0017] As another solution, the opening and closing assembly includes a slider and an elastic member, and the slider is elastically connected to the bottom cavity through the elastic member.

[0031] Embodiment 1:

[0032] like Figure 1 As shown, an embodiment of the present invention provides a vertical scanning pen, including a scanning pen body 1, a camera module and a fixed component. The camera module includes a local camera 2 and a global camera 3. The local camera 2 realizes local scanning and completes the line-by-line recognition of characters, words and sentences. The global camera 3 realizes a large-scale global scanning and can capture images of the entire page of books, test papers, etc., and complete functions such as fingertip reading and intelligent correction. Among them, the bottom end of the scanning pen body 1 is the pen head 4, the local camera 2 is connected to the pen head 4, and the global camera 3 is connected to the top of the scanning pen body 1. In other embodiments, the local camera 2 and the global camera 3 can also be combined into one and arranged at the pen head 4. When a global scan is required, the scanning pen only needs to be turned upside down and the global function of the camera is turned on.

[0033] When performing a local scan, the user can slide the pen tip 4 over the target scanning area just like operating a conventional scanning pen. When performing a global scan, the user only needs to open the shooting angle in front of the global camera 3 to ensure that the global camera 3 is at a better scanning height and angle, and then the global scan can be successfully completed, and global recognition or fingertip reading can be performed.

[0034] The fixing component is used to fix the scanning pen body 1 to the support surface, so that the scanning pen body 1 stands on the support surface. Therefore, relying on the supporting function of the support member, the user can place the scanning pen directly on the desktop during global scanning, so that the top end (or pen head 4) of the scanning pen body 1, that is, the global camera 3 stands upright, so that the global camera 3 can be kept in a better position for capturing the global image, and the user only needs to turn the pages of the book one by one to accurately complete the whole book recognition, etc., which improves the convenience of operation.

[0035] In this embodiment, the fixed component is a pen cap 5, and the pen cap 5 can cover the top of the scanning pen body 1 and / or the pen tip 4. Therefore, when the scanning pen is not in use, the pen cap 5 can be covered at the pen tip 4 to seal and protect the entire pen tip 4. When a local scan is required, the pen tip 4 can be opened and covered at the top of the scanning pen body 1 to prevent the pen cap 5 from being lost. When a global scan is required, if the global camera 3 is located at the top of the scanning pen body 1, the pen cap 5 is covered at the pen tip 4, and the scanning pen is placed directly on the desktop. The scanning pen is stably supported by the pen cap 5. In addition, the pen tip is not in a pressed or working state when the scanning pen is erected on the desktop, so as to effectively prevent the pen tip 4 from being damaged or being in a pressed working state for a long time. The power consumption problem caused by the long-term pressing and working state. If the global camera 3 is located at the pen tip 4, the pen cap 5 is covered at the top of the scanning pen body 1, and the scanning pen is inverted and placed on the desktop.

[0036] In this embodiment, a suction cup module is arranged on the pen cap 5, and the suction cup module can be adsorbed and fixed on a supporting surface such as a desktop, so that the pen cap 5 can be stabilized on the desktop without falling down by relying on the negative pressure effect.

[0037] At the same time Figure 2 As shown, in this embodiment, the pen cap 5 includes a cavity 6 and a bottom cavity 7. The cavity 6 is used to accommodate the top end or pen tip 4 of the scanning pen body 1, and the bottom cavity 7 is used to install the suction cup module, so that the pen cap 5 can accommodate and support the scanning pen, and be adsorbed and fixed on a supporting surface such as a desktop.

[0038] In this embodiment, the suction cup module includes a suction cup 8, an air inlet channel 9 and an opening and closing component. Among them, a first through hole is opened at the bottom of the bottom cavity 7, and the suction cup 8 is installed at the first through hole. At the same time, the suction cup 8 is opened with a second through hole, and the air inlet channel 9 adopts a curved pipe structure, and the first end is connected to the second through hole of the suction cup 8. The second end of the air inlet channel 9 is an air inlet 10, which is arranged outside the bottom cavity 7 (or other positions, as long as it can be connected to the outside world). The opening and closing component is arranged on the air inlet channel 9, preferably close to the first end, to control the opening and closing of the air inlet channel 9.

[0039] As a further improvement, in order to make the installation and removal of the suction cup 8 more convenient, so that the user can replace the suction cup 8 by himself when the suction cup 8 is damaged, the suction cup module in this embodiment also includes a T-shaped frame 11. Among them, the T-shaped frame 11 is provided with a third through hole 12, the T-shaped frame 11 passes through the second through hole and is sleeved on the first through hole, and the suction cup 8 is pressed and fixed on the bottom of the cavity 6 by the annular edge of the T-shaped frame 11. In addition, the third through hole of the T-shaped frame 11 is connected to the second through hole of the suction cup 8, and is connected to the first end of the air inlet channel 9, so that the suction cup 8 can exhaust and inlet air through the third through hole 12 of the T-shaped frame 11.

[0040] As a preferred implementation, in this embodiment, the first through hole is a threaded hole, and the T-frame 11 is formed with an external thread corresponding to the threaded hole. Therefore, the T-frame 11 is detachably connected to the bottom cavity 7 by threaded cooperation, which is convenient for disassembly and replacement.

[0041] In this embodiment, the opening and closing assembly includes a driving part 13, a screw 14, a connecting rod 15 and a piston 16. The driving part 13 is transmission-connected to the screw 14 to drive the screw 14 to rotate, so that the connecting rod 15 threadedly connected to the screw 14 moves, and controls the piston 16 fixedly connected to the connecting rod 15 to be inserted into the intake channel 9 to close the intake channel 9, or to withdraw from the intake channel 9 to open the intake channel 9.

[0042] As a preferred embodiment, the driving part is a stepper motor, which drives the lead screw 14 to rotate by a preset angle, so that the piston 16 is just inserted into the air intake passage 9, or withdraws from the air intake passage 9. Of course, the driving part 13 in this embodiment is not limited to the form of a stepper motor, as long as it can drive the lead screw 14 to rotate.

[0043] As a preferred embodiment, the first end of the connecting rod 15 is threadedly connected to the lead screw 14, and the second end of the connecting rod 15 is also sleeved on a guide rod 17 installed in the bottom cavity 7. The displacement of the connecting rod 15 is guided by the guide rod 17, so that the displacement of the connecting rod 15 and the piston 16 is more precise and stable.

[0044] In this embodiment, a one-way exhaust port is also arranged on the suction cup 8 for directly exhausting the gas in the suction cup 8 . Therefore, when the suction cup 8 is exhausted, it is directly exhausted through the one-way exhaust port without exhausting from the air inlet channel 9 .

[0045] In the default state, the piston 16 of the opening and closing assembly is inserted into the air inlet channel 9 and closed. When the scanning pen body 1 is inserted into the pen cap 5 and stands on the desktop, the suction cup 8 at the bottom of the pen cap 5 will exhaust the gas under the gravity or the downward force applied by humans, and directly exhaust the gas through the one-way exhaust port, so that the pen cap 5 and the scanning pen body 1 can stand stably on the desktop. When the user needs to remove the scanning pen, the pen removal operation is triggered, and the piston 16 of the opening and closing assembly withdraws from the air inlet channel 9, so that the air inlet 10 is connected with the suction cup 8, and the gas enters the suction cup 8, so that the pen cap 5 (or the entire scanning pen) can be easily removed.

[0046] In this embodiment, there is no specific limitation on triggering the pen picking operation, which can be implemented by one or more combinations of methods such as pressure sensors, gestures, voice control, touch screens, physical buttons, etc.

[0047] Embodiment 2:

[0048] At the same time Figure 3 As shown, embodiment 2 of the present invention provides another vertical scanning pen, which is mainly different from embodiment 1 in the form of the opening and closing component.

[0049] In this embodiment, the opening and closing component includes a magnetic plug 18 and an electromagnet 19. The magnetic plug 18 is inserted into the air intake channel 9 to close the air intake channel 9, or withdrawn from the air intake channel 9 to open the air intake channel 9. The electromagnet 19 is arranged corresponding to the magnetic plug 18. 19 switches the polarity by a given current, thereby generating a repulsive force or an attractive force on the magnetic plug 18.

[0050] Among them, a limiting structure 20 is arranged on the air inlet channel 9, and the limiting structure 20 is used to prevent the magnet plug 18 from being completely moved out of the air inlet channel 9, so as to avoid the subsequent inability to insert and close the air inlet channel 9.

[0051] In the default state, the electromagnet 19 and the magnetic plug 18 generate a repulsive force, so that the magnetic plug 18 remains in the air inlet channel 9 to close it. When the scanning pen body 1 is inserted into the pen cap 5 and stands on the desktop, the suction cup 8 at the bottom of the pen cap 5 discharges the gas under the gravity or the downward force applied by humans, and directly exhausts the gas through the one-way exhaust port, so that the pen cap 5 and the scanning pen body 1 stand stably on the desktop. When the user needs to remove the scanning pen, the pen removal operation is triggered, and the electromagnet 19 switches the polarity so that the magnetic plug 18 is attracted and withdraws from the air inlet channel 9, so that the air inlet 10 is connected with the suction cup 8, and the gas enters the suction cup 8, so that the pen cap 5 (or the entire scanning pen) can be easily removed.

[0052] Similarly, triggering the pen picking operation can be achieved by one or more combinations of methods such as pressure sensors, gestures, voice control, touch screens, physical buttons, etc.

[0053] Embodiment 3:

[0054] At the same time Figure 4As shown, embodiment 3 of the present invention provides another vertical scanning pen, which is mainly different from embodiments 1 and 2 in the form of the opening and closing component.

[0055] In this embodiment, the opening and closing assembly includes a slider 21 and an elastic member 22. The slider 21 is elastically connected to the bottom cavity 7 through the elastic member 22. The slider 21 is inserted into the air inlet channel 9 to close the air inlet channel 9, or withdraws from the air inlet channel 9 to open the air inlet channel 9. At the same time, a control block 23 is connected to the slider 21, and one end of the control block 23 is exposed to the outside of the bottom cavity 7, so that the user can conveniently control the position of the slider 21 outside the bottom cavity 7.

[0056] Among them, the elastic member 22 is a compression spring, which continuously applies elastic force to the slider 21, so that the slider 21 remains in the air inlet channel 9 when no external force is applied, that is, the slider 21 closes the air inlet channel 9 in the default state. When the scanning pen body 1 is inserted into the pen cap 5 and stands on the desktop, the suction cup 8 at the bottom of the pen cap 5 discharges the gas under the gravity or the downward force applied by humans, and directly exhausts the gas through the one-way exhaust port, so that the pen cap 5 and the scanning pen body 1 stand stably on the desktop. When the user needs to remove the scanning pen, the control block 23 is directly moved to make the slider 21 withdraw from the air inlet channel 9, and the air inlet is connected to the suction cup 8. After the gas enters the suction cup 8, the pen cap 5 (or the entire scanning pen) is directly removed.

[0057] The opening and closing assembly provided by this embodiment has a simpler structure and lower manufacturing and maintenance costs than embodiments 1 and 2.

[0058] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
