It is not only easy to operate, but also can greatly improve work and study efficiency, and is very popular among people.

[0003] At present, the scanning windows of scanning pens or dictionary pens on the market are all fixed. When faced with some relatively dense text, images and other information, the scanned content will be scanned across lines, resulting in the scanned information not being what the user wants to scan. The user needs to select the required information from it, which is not only time-consuming and laborious, but also the scanning is not accurate enough, affecting the user experience. Summary of the invention

[0004] The purpose of the present invention is to provide a scanning pen that can autonomously adjust the width of the scanning window according to demand, avoid cross-line scanning, and improve scanning accuracy.

[0005] The technical solution provided by the present invention is as follows:

[0006] A scanning pen, comprising:

[0007] A housing, wherein a scanning window is provided at one end of the housing;

[0008] A scanning module, disposed in the housing and corresponding to the scanning window;

[0009] A pen tip is arranged at one end of the shell where the scanning window is provided, and the pen tip includes a bracket, a first support member and a second support member. One end of the bracket is movably connected to the shell, and the first support member and the second support member are arranged at the other end of the bracket and are located on both sides of the scanning window along the width direction of the shell. The first support member is movable along the width direction of the shell to partially block the scanning window, thereby adjusting the scanning width of the scanning module.

[0010] In some embodiments, a first limiting portion is provided on the first support member along the width direction of the shell, and a second limiting portion is provided on the bracket along the width direction of the shell. The first limiting portion cooperates with the second limiting portion to limit the first support member so that the first support member can move along the width direction of the shell.

[0011] In some embodiments, the first limiting portion is a T-shaped slot or a dovetail slot;

[0012] The second limiting portion is a protrusion matched with the first limiting portion.

[0013] In some embodiments, an adjustment component is further included, wherein the adjustment component is connected to the first support member and is used to drive the first support member to move along the width direction of the shell.

[0014] In some embodiments, a toggle switch for turning on or off the scanning function is further included. The toggle switch is disposed in the housing and above the pen tip. The pen tip is movable along the length direction of the housing to turn on or off the toggle switch.

[0015] In some embodiments, a return spring is further included, wherein the return spring is disposed in the housing, an abutment portion is provided in the housing, one end of the return spring abuts against the abutment portion, and the other end abuts against the pen tip. In a scanning state, the pen tip moves upward to compress the return spring and toggle the toggle switch to turn on the scanning function. In a non-scanning state, the return spring is reset, and the pen tip moves downward to reset.

[0016] In some embodiments, the adjustment assembly includes a sleeve, an adjustment knob, a push rod and a ball, the sleeve is connected to the outer shell, the adjustment knob is connected to the push rod, one end of the push rod is threadedly connected to the sleeve, a portion of the ball is located inside the other end of the push rod, and the other portion protrudes from the push rod and contacts the first support member, and when the adjustment knob is rotated, the push rod moves along the width direction of the outer shell to push the first support member to move along the width direction of the outer shell.

[0017] In some embodiments, the adjustment assembly further includes a ball spring, which is disposed in the push rod and has one end abutting against the push rod and the other end abutting against the ball.

[0018] In some embodiments, the second support member is movable along a width direction of the housing.

[0019] In some embodiments, rollers are respectively provided at one end of the first support member and the second support member away from the housing; or, one end of the first support member and the second support member away from the housing is a smooth arc surface.

[0020] The technical effect of the present invention is that by setting a first support member movable along the width direction of the shell, when encountering information such as text content with a small line spacing or a small font, it is only necessary to move the first support member along the width direction of the shell so that the first support member can block a part of the scanning window, and the scanning module can only scan through the unblocked area of ​​the scanning window, and the scanning width of the scanning window becomes smaller to accurately obtain the content to be scanned, prevent cross-line scanning, and improve the scanning recognition accuracy. Correspondingly, when the user needs to scan text information with a large font or a large line spacing, the first support member is moved in the opposite direction so that the first support member no longer blocks the scanning window, and the scanning width of the scanning window becomes larger. The scanning module can scan text information within a wider range to obtain complete scanning information, avoid incomplete scanning, and improve scanning accuracy.

[0037] In one embodiment of the present application, Figure 1 and Figure 2As shown, a scanning pen includes a shell 10, a scanning module and a pen tip 20. A scanning window 101 is provided at one end of the shell 10; the scanning module is arranged in the shell 10 and corresponds to the scanning window 101; the pen tip 20 is arranged at the end of the shell 10 where the scanning window 101 is provided, and the pen tip 20 includes a bracket 21, a first support member 22 and a second support member 23. One end of the bracket 21 is movably connected to the shell 10, the first support member 22 and the second support member 23 are arranged at the other end of the bracket 21 and are located on both sides of the scanning window 101 along the width direction of the shell 10, and the first support member 22 can be moved along the width direction of the shell 10 to partially block the scanning window 101, thereby adjusting the scanning width of the scanning module.

[0038] Specifically, the extension direction of the housing 10 is the length direction of the housing 10. Figure 1 In the direction indicated by the arrow a, the width direction of the housing 10 is Figure 1 In the direction indicated by the middle arrow b, one end of the housing 10 scans the window 101, the scanning module is arranged in the housing 10 and faces the scanning window 101, the first support member 22 and the second support member 23 are located on both sides of the scanning window 101 along the width direction, wherein the width direction of the scanning window 101 is consistent with the width direction of the housing 10, and the optical path channel of the scanning module is formed between the first support member 22 and the second support member 23. When the scanning pen is working, the scanning module scans the book to be scanned through the scanning window 101 and the optical path channel. The scanning module is an existing structure, for example, the scanning module can be a camera module, and scanning and recognition are performed through the camera module, which will not be described in detail here.

[0039] The pen tip 20 includes a bracket 21, a first support member 22 and a second support member 23. The bracket 21 is movably installed in the shell 10. The bracket 21 is movable relative to the shell 10 along the length direction of the shell 10. The first support member 22 and the second support member 23 are both installed on the bracket 21. The second support member 23 can be fixedly connected to the bracket 21 or formed integrally with the bracket 21. The first support member 22 is movable relative to the bracket 21 along the width direction of the scanning window 101. When the first support member 22 moves along the width direction of the scanning window 101 toward the second support member 23 to block a part of the scanning window 101, the scanning width of the scanning window 101 can be adjusted, thereby realizing the adjustment of the scanning width of the scanning pen.

[0040] When the user uses the scanning pen to scan, the first support member 22 and the second support member 23 of the pen head 20 are in contact with the book to be scanned, and then the scanning pen is moved. The scanning module scans the book to be scanned through the scanning window 101 and the optical path, and then scans and translates or interprets the text, graphics and other information on the book to be scanned, so as to facilitate the user's study, work, etc. When encountering information such as text content with small line spacing or small font, it is only necessary to move the first support member 22 along the width direction of the housing 10 so that the first support member 22 can block a part of the scanning window 101. The scanning module can only scan through the unblocked area of ​​the scanning window 101, and the scanning width of the scanning window 101 becomes smaller to accurately obtain the content to be scanned, prevent cross-line scanning, and improve the scanning recognition accuracy. Accordingly, when the user needs to scan text information with a larger font or a larger line spacing, the first support member 22 is moved in the opposite direction so that the first support member 22 no longer blocks the scanning window 101, and the scanning width of the scanning window 101 becomes larger, and the scanning module can scan text information within a wider range to obtain complete scanning information. In this embodiment, by providing a first support member 22 that is movable along the width direction of the housing 10, the user can adjust the scanning range of the scanning pen according to actual use needs, avoid cross-line scanning or incomplete scanning, and improve scanning accuracy and user experience.

[0041] As a simple variation, the second support member 23 is movably connected to the bracket 21, and the second support member 23 is movable relative to the bracket 21 along the width direction of the housing 10. When adjusting the width of the scanning window 101, the user can choose to move the first support member 22 or the second support member 23, or move the first support member 22 and the second support member 23 at the same time, thereby improving the convenience and speed of adjusting the width of the scanning window 101. The second support member 23 and the bracket 21 can be movably connected in the same manner as the first support member 22 and the bracket 21.

[0042] Furthermore, if Figure 3 As shown, the housing 10 includes a bottom shell 11 and a front shell 12. The front shell 12 is covered on the bottom shell 11 to form a storage space for accommodating electronic components of the scanning pen. A display screen 121 is provided on the side of the front shell 12 away from the bottom shell 11. The display screen 121 is used to display the scanned content. The back side of one end of the bottom shell 11 is recessed inward to form a scanning window 101. The scanning module is installed at the scanning window 101. Figure 2 As shown, one end of the housing 10 having a scanning window 101 is also provided with two supporting feet 13, and the two supporting feet 13 are located on both sides of the scanning window 101 along the width direction, and the first supporting member 22 and the second supporting member 23 are respectively located in one supporting foot 13, and an opening is provided on the inner side of the supporting foot 13 on which the first supporting member 22 is installed, so that the first supporting member 22 can be moved out of the supporting foot 13 along the width direction of the housing 10.

[0043] In some embodiments, Figure 4 As shown, a first limiting portion 221 is provided on the first support member 22 along the width direction of the housing 10, and a second limiting portion 211 is provided on the bracket 21 along the width direction of the housing 10. The second limiting portion 211 extends along the width direction of the housing 10, and the first limiting portion 221 cooperates with the second limiting portion 211 to limit the position, so that the first support member 22 can move along the width direction of the housing 10. In this embodiment, the bracket 21 can be made of metal, and the first support member 22 can be made of plastic. The first support member 22 and the bracket 21 are connected by the first limiting portion 221 and the second limiting portion 211 to limit the position, so that the first support member 22 can move relative to the bracket 21 without falling off the bracket 21. Preferably, the first limiting portion 221 is a T-shaped slot or a dovetail slot; the second limiting portion 211 is a protrusion adapted to the first limiting portion 221, and the first support member 22 and the bracket 21 are connected and limited by the T-shaped slot or the dovetail slot to ensure a good connection between the first support member 22 and the bracket 21.

[0044] In some embodiments, Figure 5 As shown, it also includes an adjustment component 30, which is connected to the first support member 22 and is used to drive the first support member 22 to move along the width direction of the housing 10. By driving the first support member 22 to move through the adjustment component 30, the user can adjust the width of the scanning window 101 conveniently, thereby improving the convenience of user adjustment and the use experience.

[0045] Furthermore, if Figure 5 and Figure 6 As shown, the scanning pen also includes a toggle switch 40 for turning on or off the scanning function. The toggle switch 40 is disposed in the housing 10 and located above the pen head 20. The pen head 20 is movable along the length direction of the housing 10 to turn on or off the toggle switch 40.

[0046] In this embodiment, the bracket 21 of the pen tip 20 is arranged in the shell 10, and a limiting frame is provided in the shell 10, so that the bracket 21 can move up and down relative to the shell 10 inside the shell 10. The movable range of the pen tip 20 can be 1 to 2 mm. When the user uses the scanning pen, if he needs to scan content, he presses the pen tip 20 downward to move the pen tip 20 upward relative to the shell 10. When the bracket 21 of the pen tip 20 moves upward, the toggle switch 40 is turned on to turn on the scanning function of the scanning pen, so that the scanning pen can scan the content that needs to be identified.

[0047] Furthermore, if Figure 6As shown, it also includes a reset spring 50, which is arranged in the housing 10. The housing 10 is provided with an abutting portion. One end of the reset spring 50 abuts against the abutting portion, and the other end abuts against the pen tip 20. In the scanning state, the pen tip 20 moves upward to compress the reset spring 50 and toggle the toggle switch 40 to turn on the scanning function. In the non-scanning state, the reset spring 50 is reset, and the pen tip 20 moves downward to reset. When scanning is required, the housing 10 is pressed downward to move the pen tip 20 upward relative to the housing 10. When the pen tip 20 moves upward, the reset spring 50 is compressed and the toggle switch 40 is toggled, turning on the scanning function of the scanning pen and entering the scanning function mode state; when scanning is not required, the downward pressure on the housing 10 is removed, so that the pen tip 20 automatically resets under the action of the reset spring 50, and the toggle switch 40 also automatically resets to turn off the scanning function.

[0048] Furthermore, if Figure 7 and Figure 8 As shown, the adjustment assembly 30 includes a sleeve 31, an adjustment knob 32, a push rod 33 and a ball 34. The sleeve 31 is connected to the housing 10, and the adjustment knob 32 is connected to the push rod 33. One end of the push rod 33 is threadedly connected to the sleeve 31, and a portion of the ball 34 is located inside the other end of the push rod 33, and the other portion of the ball 34 protrudes out of the push rod 33 and contacts the first support member 22. When the adjustment knob 32 is rotated, the push rod 33 moves along the width direction of the housing 10 to push the first support member 22 to move along the width direction of the housing 10.

[0049] In this embodiment, the push rod 33 is in contact with the first support member 22 through the ball 34. When the pen head 20 drives the first support member 22 to move up and down relative to the housing 10, the adjustment component 30 does not move, and the ball 34 contacts the side wall of the first support member 22, thereby reducing the friction between the adjustment component 30 and the side wall of the first support member 22. The push rod 33 is threadedly connected to the sleeve 31, and the push rod 33 is extended and retracted by rotating the adjustment knob 32 to control the movement of the first support member 22 along the width direction of the housing 10.

[0050] Preferably, if Figure 8 As shown, the adjustment assembly 30 further includes a ball spring 35, which is disposed in the push rod 33, and one end of the ball spring 35 abuts against the push rod 33, and the other end of the ball spring 35 abuts against the ball 34. The ball 34 is connected to the push rod 33 through the ball spring 35, and when the pen head 20 drives the first support member 22 to move up and down relative to the housing 10, the friction between the first support member 22 and the ball 34 can be adjusted by the ball spring 35, so that the pen head 20 moves up and down more smoothly.

[0051] Furthermore, if Figure 1 and Figure 2As shown, the first support member 22 and the second support member 23 are respectively provided with rollers 24 at one end away from the housing 10; when scanning, the two rollers 24 located at the bottom end of the scanning pen roll on the surface of the scanned object, which can reduce the friction resistance during the scanning process, making the scanning process smoother and providing a better user experience.

[0052] Of course, in addition to setting the roller 24 at the bottom end of the first support member 22 and the second support member 23, the end of the first support member 22 and the second support member 23 away from the outer shell 10 can also be set to a smooth arc surface, which can also reduce the friction of the scanning pen moving on the surface of the scanned object and improve the smoothness of the scanning and the user experience.

[0053] The above is only 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 principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
