[0034] Combine the following Figure 1-Figure 7 The utility model describes a dictionary pen.
[0035] The dictionary pen provided by the utility model comprises a pen body 1, a camera module 2, a main control board 3, a light emitting body 4 and a light averaging lens 5. Figure 2 As shown, the scanning end of the pen body 1 is provided with a scanning window 11, and the scanning window 11 is used to frame the scanning content. The camera module 2 is installed on the pen body 1 and is located on the side of the scanning window 11 away from the scanning end of the pen body 1. Figure 3 As shown, the main control board 3 is installed in the pen body 1, the light-emitting body 4 is fixed to the pen body 1, and the light-emitting body 4 and the camera module 2 are electrically connected to the main control board 3 respectively. Figure 4 As shown, the light-homogenizing lens 5 is fixed to the pen body 1 , and the light emitted by the light-emitting body 4 is refracted by the light-homogenizing lens 5 to illuminate the content to be scanned.
[0036] The scanning end of the pen body 1 is provided with a scanning window 11. When scanning, the scanning window 11 faces the scanning medium and is used to frame the content to be scanned. As the dictionary pen moves along the scanning medium surface 100, the camera module 2 captures the image of the content to be scanned. Figure 1 and Figure 2 As shown, the scanning end of the pen body 1 is also provided with an observation window 12, which is arranged on the front of the dictionary pen and is made of a transparent material. During the scanning process, the user can view the specific content selected by the scanning window 11 through the observation window 12, thereby improving the accuracy of the scanning. The front of the dictionary pen is the side of the dictionary pen facing the user during scanning.
[0037] The interior of the pen body 1 is hollow, and the main control board 3 is fixed to the interior of the pen body 1 by screws or other fasteners. The main control board 3 includes a circuit board and electronic devices arranged on the circuit board, and the electronic devices can process the image information collected by the camera module 2 in real time, and can communicate with the cloud server to realize real-time translation.
[0038] Specifically, the light source 4 may be a light strip or a light bead, and the light source 4 and the light-homogenizing lens 5 may be directly fixed to the pen body 1, or may be fixed to the pen body 1 through other components. Figure 4 and Figure 5 As shown, the light emitted by the luminous body 4 passes through the homogenizing lens 5 and irradiates the scanning medium surface 100, illuminating the content to be scanned, and facilitating the scanning of the camera module 2. The homogenizing lens 5 includes a plurality of optical lenses or a single prism, and the reflected light of the luminous body 4 passing through the homogenizing lens 5 does not affect the normal scanning of the camera module 2, and the refracted light of the luminous body 4 passing through the homogenizing lens 5 can provide fill light for the scanning of the camera module 2.
[0039] In the dictionary pen provided by the utility model, the light refracted by the light-emitting body 4 through the homogenizing lens 5 converges on the surface 100 of the medium to be scanned, illuminating the content to be scanned, and the uniformity of the light is better everywhere. Compared with the traditional method of setting a fill light, it can effectively avoid uneven fill light, which helps to improve the scanning quality of the camera module 2.
[0040] In a specific embodiment, if Figure 6 As shown, the light averaging lens 5 includes a first refractive surface 51 and a second refractive surface 52. The light emitting body 4 is mounted outside the camera module 2, and the light emitted by the light emitting body 4 passes through the first refractive surface 51 and the second refractive surface 52 in sequence to illuminate the content to be scanned.
[0041] The location of the light averaging lens 5 is determined according to the relative location of the light emitting body 4 and the area to be illuminated. Figure 4 and Figure 7 As shown, the homogenizing lens 5 is arranged below the light emitting body 4. The homogenizing lens 5 includes at least a first refractive surface 51 and a second refractive surface 52. The light emitted by the light emitting body 4 undergoes two refractions, and the direction of the light changes, making the installation position of the light emitting body 4 more flexible and convenient for installation.
[0042] For example, the homogenizing lens 5 includes a lens body and a mounting seat fixedly connected to the lens body. The lens body is a prism or has a triangular tip; the mounting seat is fixed on the pen body 1 and is arranged toward the outside to avoid external light interference while maintaining the consistency of the outer wall of the dictionary pen. Specifically, the homogenizing lens 5 is a prism. For example, Figure 6 As shown in , the cross section of the prism is a right triangle. Figure 4 and Figure 5As shown, the light emitting body 4, the light averaging lens 5 and the camera module 2 are arranged on the same bracket, which facilitates installation.
[0043] Specifically, the light emitting body 4 is a strip light strip, and the number of light strips can be set as required.
[0044] like Figure 3 and Figure 4 As shown, the dictionary pen further comprises a mounting bracket 21, the mounting bracket 21 is provided with a mounting groove, and the camera module 2 is clamped in the mounting groove. The mounting bracket 21 is fixed to the pen body 1, and the inner side of the mounting bracket 21 serves as a fixing surface of the light emitting body 4.
[0045] The material of the mounting bracket 21 is the same as that of the pen body 1. For example, both are injection molded parts. The mounting bracket 21 is fixed to the scanning end of the pen body 1 by screws, such as Figure 4 As shown, the outer side of the mounting bracket 21 is flush with the wall surface of the pen body 1, the inner side of the mounting bracket 21 is a flat surface, and the light-emitting body 4 is fixed on the flat surface. Specifically, the light-emitting body 4 includes a light board, and the light board is fixed on the inner side of the mounting bracket 21. The inner wall of the pen body 1 is provided with a step surface, the top of the mounting bracket 21 is against the step surface, part of the outer wall of the mounting bracket 21 is fitted with the thin-walled section of the step surface, and part of the wall surface of the mounting bracket 21 is exposed to the outside to form the top of the scanning window 11. Among them, the inner side of the mounting bracket 21 is opposite to the outer side of the mounting bracket 21, and the inner side of the mounting bracket 21 refers to the side of the mounting bracket 21 that is closer to the inside of the pen body 1. It can be understood that the bottom of the mounting groove is provided with a through hole for scanning.
[0046] In order to prevent the camera module 2 from moving along the length direction of the pen body 1, the dictionary pen also includes a snap-fit bracket 22, which is snap-fitted into the notch of the installation slot to fix the camera module 2 in the installation slot.
[0047] like Figure 4 As shown, a sealing foam 8 is sandwiched between the bottom of the mounting groove and the camera module 2. A through hole for scanning is provided on the pen body 1 corresponding to the camera module 2, and the lens of the camera module 2 faces the through hole and the through hole at the bottom of the mounting groove to ensure that scanning can be performed. On the one hand, the sealing foam 8 can prevent external dust from entering the camera module 2 and affecting the scanning quality; on the other hand, the sealing foam 8 can also play a buffering role, preventing the camera module 2 from vibrating, improving the stability of the camera module 2, and improving the scanning quality.
[0048] like Figure 3 and Figure 5As shown, the dictionary pen also includes a flexible circuit board 6 electrically connected to the main control board 3. The flexible circuit board 6 includes a horizontal plate and a vertical plate connected vertically. The camera module 2 is fixedly mounted on the horizontal plate, and the horizontal plate is fixed to the notch of the mounting groove. The light emitter 4 is fixed to the vertical plate, and the vertical plate is fixed to the inner side of the mounting bracket 21. Thus, the camera module 2, the main control board 3 and the light emitter 4 can be electrically connected by means of a flexible circuit board 6. Of course, the camera module 2 and the light emitter 4 can also be connected to the main control board 3 through a flexible circuit board respectively.
[0049] like Figure 4 As shown, the mounting bracket 21 is used to mount the camera module 2, which is fixed to the pen body 1 by screws or fixed to the scanning end of the pen body 1 by bonding or clamping. The camera module 2 is electrically connected to the horizontal plate, and the light emitting body 4 is electrically connected to the vertical plate, so that the light emitting body 4 and the camera module 2 are staggered along the length direction of the pen body 1. The horizontal plate is placed horizontally at the slot of the mounting groove, and the horizontal plate is constrained by the opposite side slot wall of the mounting groove and the buckle bracket 22. Figure 5 As shown, the light-emitting body 4 is located at the lower side of the camera module 2. When scanning, the camera module 2 faces the scanning medium surface 100, and the light-emitting body 4 is refracted from the side of the observation window 12 to illuminate the content to be scanned, which not only provides lighting for the user to view, but also provides fill light for the scanning of the camera module 2.
[0050] A connector 31 is installed on the main control board 3, and the flexible circuit board 6 is bent upward and connected to the connector 31. The camera module 2 and the light emitter 4 are both installed on the flexible circuit board 6. Therefore, the camera module 2 and the light emitter 4 are connected to the main control board 3 respectively by means of the flexible circuit board 6, so that the main control board 3 can control the switch of the camera module 2 and the switch of the light emitter 4.
[0051] like Figure 4 As shown, the camera module 2 is horizontally arranged along the width direction of the pen body 1, and the bottom end of the mounting bracket 21 has an inclined surface which forms an acute angle with the front surface of the pen body 1, and the inclined surface is provided with a light-transmitting hole for scanning by the camera module 2, and a light-transmitting mirror 7 is installed in the light-transmitting hole.
[0052] The inclined surface is located below the mounting groove, and after the camera module 2 is fixed inside the mounting groove, the content to be scanned on the scanning medium is obtained through the light-transmitting mirror 7. The light-transmitting mirror 7 can not only seal the internal cavity of the pen body 1 to prevent external dust and sewage from entering the pen body 1, but also ensure that the camera module 2 can obtain the image of the content to be scanned.
[0053] In addition, the camera module 2 and the light emitting body 4 can also be installed at the same height in the length direction of the pen body 1 , and the camera module 2 can be ensured not to be affected by the light reflected by the light emitting body 4 by setting the position of the light averaging lens 5 .
[0054] Optional, such as Figure 4 and Figure 5 As shown, the light emitted by the light emitting body 4 is refracted by the light averaging lens 5 and then scans the medium surface 100 to form a bright area, and the range of the bright area coincides with the shooting range of the camera module 2.
[0055] It should be noted that the range of the bright area completely overlaps with the shooting range of the camera module 2; or, the range of the bright area is slightly smaller than the shooting range of the camera module 2 by 2% to 10%, ensuring that the light source 4 can fully illuminate the shooting range of the camera module 2.
[0056] like Figure 3 As shown, the pen body 1 includes a first shell 13 and a second shell 14, and the first shell 13 and the second shell 14 are detachably connected. The first shell 13 is the front side of the pen body 1, and the second shell 14 is the back side of the pen body 1. The observation window 12 is arranged on one side of the first shell 13 close to the scanning end.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
