DETAILED DESCRIPTION
[0043] The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.
[0044] According to an embodiment of the present invention, an intelligent scanning device is provided.
[0045] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.
[0046] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.
[0047] like Figure 1-Figure 4 as well as Figure 6As shown, according to the embodiment of the present application, the intelligent scanning device includes a shell 10 and a camera module, wherein a main control component and a pressure sensing component 30 and a sensor component 40 electrically connected to the main control component are arranged in the shell 10, an opening 11 penetrating in the up-down direction is arranged at the front end of the shell 10, a first beam 12 formed at the front end of the shell 10 is arranged on the front side of the opening 11, a trigger component 50 is arranged on the first beam 12, a pressure sensing component 30 is arranged at the front end of the shell 10, and the trigger component 50 abuts against the pressure sensing component 30, and the intelligent scanning device is configured as follows: in response to the trigger component 50 abutting against the scanning medium to apply a force to the pressure sensing component 30 to generate a scanning trigger signal; after receiving the scanning trigger signal, the main control component controls the camera module to start collecting images of the scanning medium; in response to the trigger component 50 leaving the scanning medium, the main control component controls the camera module to continue collecting images of the scanning medium with an expanded shooting field of view; in response to the sensor component 40 detecting that a preset stop condition is met, the main control component controls the camera module to stop collecting images of the scanning medium; and the collected multiple images are screened and identified to determine the target scanning content.
[0048] To elaborate, by setting the first crossbeam 12, the trigger component 50 can be set on the first crossbeam 12, which can allow the size of the trigger component 50 to be increased accordingly, so that the force applied to the pressure sensing component 30 by the trigger component 50 when it is pressed from the front meets the starting condition, and the first crossbeam 12 is used to increase the structural strength of the front end of the shell 10. The trigger component 50 is used to contact the object to be tested, and feed back the force it receives to the pressure sensing component 30. The pressure sensing component 30 converts the force it receives into an electrical signal, which is then transmitted to the main control component to confirm whether the intelligent scanning device needs to be started. Among them, the pressure sensing component 30 is electrically connected to the main control component, and the trigger component 50 is mechanically connected to the pressure sensing component 30. The connection here refers to a broad connection. As long as direct contact can achieve force transmission, the trigger component 50 and the pressure sensing component 30 do not have to be connected in a narrow sense.
[0049] It is understandable that by arranging the trigger assembly 50 on the first crossbeam 12, there can be enough installation space for the trigger assembly 50 to be installed. Therefore, the size of the trigger assembly 50 can be appropriately increased, thereby avoiding the possibility that the trigger assembly 50 is easily accidentally triggered due to too little force.
[0050] The pressure sensing component 30 is electrically connected to the main control component, and the trigger component 50 is mechanically connected to the pressure sensing component 30. The connection here refers to a broad connection, as long as direct contact can achieve force transmission. The trigger component 50 and the pressure sensing component 30 do not have to be connected in a narrow sense.
[0051] The intelligent scanning device can generate a scanning trigger signal in response to the trigger component 50 pressing against the scanning medium to apply force to the pressure sensing component 30. The intelligent scanning device can start to capture images after the trigger component 50 presses a position point of the scanning medium, which is more convenient than the long press movement operation. The scanning medium can carry text content to be scanned or translated, and the image captured of the scanning medium can include capturing an image of the text content carried by the scanning medium. In some application scenarios, the scanning medium can be paper or an ink screen. In other application scenarios, the scanning medium can be an electronic screen (non-ink screen). In other embodiments, the intelligent scanning device can be a scanning pen, a dictionary pen, a point reading pen, etc.
[0052] After receiving the scanning trigger signal, the main control component controls the camera module to start collecting images of the scanning medium. The images of the scanning medium can be collected by collecting one or more images. In particular, for the needs of querying long words, long phrases or sentences and other types of text to be queried, for example, in some embodiments, the intelligent scanning device can be controlled to collect multiple images of the scanning medium, and one or more clearer images can be screened out from the multiple images for subsequent recognition and other operations, or the multiple images can be recognized and an image with better recognition results can be selected from them. According to such a setting, the accuracy of image recognition can be improved.
[0053] Since the smart scanning device can start collecting images after the trigger component 50 presses a position point of the scanning medium, for long words, long phrases or sentences and other types of text to be queried, the closer the distance between the smart scanning device and the scanning medium, the smaller the shooting range of the camera module. Therefore, when the smart scanning device is lifted, the camera module continues to collect images. For example, in some embodiments, the multiple images collected by the camera module can be compared with the previous frame, and the image difference threshold is called. If the difference between two adjacent images is less than or equal to the difference threshold, the last frame of the image or a clear frame in the next few frames is selected. If the difference between two adjacent images is greater than the difference threshold, it means that the user has moved the smart scanning device. If the range is farther than the text to be scanned and the image is not clear enough, the subsequent image frames are discarded. Alternatively, several consecutive frames from the last frame to the front are selected for comparison (not all the acquired images are compared). If the difference is less than or equal to the difference threshold, the image of the clear frame within the first preset number range from the last frame or the last frame can be selected for analysis. Alternatively, for all the acquired image frames, images within a second preset number range are randomly selected for comparison. If the difference is less than or equal to the difference threshold, clear frames are selected for analysis. If the difference is greater than the difference threshold, new images within the second preset number range are selected for comparison until the difference is less than or equal to the difference threshold, and clear frames are selected for analysis.
[0054] The second preset number range is greater than the first preset number range.
[0055] Capturing the image of the scanned medium may include: continuously capturing the image of the scanned medium during the image capture period. According to such a setting, multiple images with continuous content can be obtained, so as to facilitate subsequent operations such as screening or splicing as needed. For example, in one embodiment, multiple images captured continuously can be spliced to form an image to be recognized including more content and perform operations such as recognition or translation. Since the image capture range of a single image is limited, the splicing of multiple images will be more conducive to expanding the range of the image obtained after splicing. According to one embodiment of the present invention, the acquisition time of a single image can be less than or equal to 8 milliseconds (ms), and such acquisition time is usually lower than the reaction time of the user, so continuous and rapid image acquisition can be achieved without affecting the user's operation and perception.
[0056] Among them, the scanning trigger signal may include at least one of the following: a click touch signal generated by the trigger component 50 clicking on the scanning medium; a continuous touch signal generated by the trigger component 50 continuously touching the scanning medium; a tactile signal generated by the trigger component 50 touching the scanning medium; a lift-off signal generated by the trigger component 50 being lifted off the scanning medium, at which time the sensor component 40 includes at least one of a distance sensor and a gyroscope; a distance signal generated when the distance between the intelligent scanning device and the scanning medium reaches a first preset distance; a vibration signal generated by the vibration of the intelligent scanning device; a first pressing signal generated when the trigger component 50 of the intelligent scanning device is pressed; a first voice control signal received by the intelligent scanning device; and a movement signal generated when the moving speed or movement acceleration of the intelligent scanning device is within a preset range.
[0057] In response to the trigger component 50 of the intelligent scanning device leaving the scanning medium, the main control component controls the camera module to continue to collect images of the scanning medium with an expanded shooting field of view, which can obtain images in a larger range and meet the user's needs for querying types of text to be queried, such as long words, long phrases or sentences.
[0058] According to the intelligent scanning device of the embodiment of the present application, the intelligent scanning device detects through the sensor component 40 that the intelligent scanning device can still perform image acquisition operations when it leaves the scanning medium, so that the intelligent scanning device can obtain a larger image acquisition range during image acquisition, or subsequently perform operations such as screening or splicing on multiple acquired images, which is beneficial to improve the accuracy of image recognition and further expand the image acquisition range, thereby enhancing the recognition ability of the intelligent scanning device, and does not require the user to perform complex operations, thereby reducing the requirements for user operations and bringing a better experience to the user. In response to the sensor component 40 detecting that the preset stop condition is met, the main control component controls the camera module to stop acquiring the image of the scanning medium. In this way, the intelligent scanning device can be controlled to stop scanning in time, which can reduce the energy consumption of the intelligent scanning device.
[0059] A click touch signal generated by the intelligent scanning device clicking on the scanning medium; a continuous touch signal generated by the intelligent scanning device continuously touching the scanning medium; a tactile signal generated by the intelligent scanning device touching the scanning medium; a lift-off signal generated by the intelligent scanning device lifting off the scanning medium; a distance signal generated when the distance between the intelligent scanning device and the scanning medium reaches a first preset distance; a vibration signal generated by the vibration of the intelligent scanning device; a first pressing signal generated when the trigger component 50 of the intelligent scanning device is pressed; a first voice control signal received by the intelligent scanning device; and a movement signal generated when the moving speed or movement acceleration of the intelligent scanning device is within a preset range.
[0060] In a specific embodiment, the smart scanning device may control the smart scanning device to start collecting images in response to a first voice control signal received by the smart scanning device. In some application scenarios, the smart scanning device may control whether to start the image collection function by receiving and recognizing a voice instruction from a user (e.g., start scanning, start collecting, start solving a problem, or start translating, etc.).
[0061] In a specific embodiment, the scanning trigger signal may be that the distance between the intelligent scanning device and the scanning medium measured by the sensor assembly 40 using laser distance measurement satisfies the first preset distance. For example, in a specific embodiment, the first preset distance may be within the focal length range of the camera module of the intelligent scanning device to ensure that a clear image can be captured. The intelligent scanning device may respond to the distance signal generated by detecting the first preset distance and control the intelligent scanning device to capture an image of the scanning medium at the first preset distance. In some further embodiments, in response to detecting that the distance between the intelligent scanning device and the scanning medium is greater than the first preset distance, the image of the scanning medium may continue to be captured.
[0062] The scanning stop condition can be generated by one or more combinations of the following conditions: the sensor component 40 detects that the distance between the smart scanning device and the scanning medium exceeds a second preset distance; detects that the distance between the smart scanning device and the scanning medium first increases and then decreases; detects that the time the smart scanning device leaves the scanning medium exceeds a preset time; detects that the moving speed or moving acceleration of the smart scanning device is outside a preset range; detects that a second pressing signal generated by pressing the trigger component 50 of the smart scanning device is detected; a second voice control signal is received via the smart scanning device; and the content contained in the recognized image meets the recognition end condition.
[0063] In addition, the content contained in the identified image meets the scanning stop condition and may include: performing correlation matching on the content contained in the multiple identified images; and in response to the correlation of the content contained in the multiple identified images being lower than a correlation threshold, stopping the recognition operation on the subsequently acquired images.
[0064] The correlation matching described above may include comparing the contents contained in multiple images to determine the degree of correlation of the contents contained in the multiple images. The closer the contents contained in the multiple images are, the higher the correlation is; the more different the contents contained in the multiple images are, the lower the correlation is. The correlation threshold can be set as needed. When the correlation between the contents contained in one part of the multiple images and another part of the images is lower than the correlation threshold, it can be determined that the part of the images does not belong to the scanning range to which the other part of the images belongs. For example, in some application scenarios, after the user uses a smart scanning device to scan or query the text to be queried, the smart scanning device may be placed randomly, so that the camera module of the smart scanning device may collect other non-related content (such as content other than the scanning medium). At this time, the recognition can be stopped and a scanning end signal can be generated.
[0065] The smart scanning device may control the smart scanning device to stop collecting images in response to receiving the second voice control signal via the smart scanning device. In some application scenarios, the smart scanning device may control whether to end the image collection function by receiving and recognizing a voice instruction from the user (e.g., stop scanning, stop collecting, stop solving problems, or stop translating, etc.).
[0066] In some embodiments, the content contained in the recognized image can be matched with the target text in a preset word library to determine whether one or more target texts are matched, where the target texts may include, for example, words, phrases, etc. The preset word library may be a word library built into the intelligent scanning device or remotely accessible. The word library may include a plurality of target texts and their interpretations, etc. In other embodiments, the content contained in the recognized image can be matched with the target text in a preset question bank to determine whether one or more target texts are matched, where the target texts may include various types of test questions, etc. The preset question bank may be a question bank built into the intelligent scanning device or remotely accessible. The question bank may include a plurality of target texts and their answers, etc.
[0067] As the distance between the intelligent scanning device and the scanning medium increases, not only can images containing longer content be captured, but in some scenarios, content containing more context can also be captured (e.g. Figure 6 The image shown in can capture two lines of text content), so the method according to the present invention can utilize the intelligent scanning device to achieve a larger image acquisition range during the period when it leaves the scanning medium, thereby helping to realize the query function of more types of content (such as articles, test questions, etc.) to be suitable for more application scenarios (such as translation, judgment questions, problem solving, etc.).
[0068] According to the intelligent scanning device of the embodiment of the present application, before responding to the trigger component 50 pressing against the scanning medium to apply force to the pressure sensing component 30 to generate a scanning trigger signal, it also includes: in response to the sensor component 40 detecting that a preset start-up condition is met, initializing the camera module to enter a low-power shooting mode.
[0069] That is to say, when the user is looking for the content to be queried, the sensor component 40 detects that the smart scanning device meets the preset startup conditions, and the smart scanning device initializes the camera module, so that the camera module enters the low-power shooting mode, shortens the startup time, thereby improving the user's quick response to the required recognition image and reducing the energy consumption in this process, thereby improving the user's experience. For example, when the sensor component 40 includes a three-axis gyroscope, the moving speed or the moving acceleration of the smart scanning device can be determined, and the preset startup conditions can include the numerical range of the moving speed or the moving acceleration, and can also include the direction range of the moving speed or the moving acceleration. For another example, when the sensor component 40 includes a tilt sensor, the tilt angle of the smart scanning device can be detected, and the preset startup conditions can include the tilt angle range and the data change time for judging the posture of the smart scanning device. For example, when the continuous change time of the motion posture data of the smart scanning device exceeds the preset time threshold, it is determined that the motion posture meets the time value condition.
[0070] The preset start condition and the distance or angle threshold of the scanning trigger signal are different. When the sensor component 40 includes a distance sensor, the intelligent scanning device determines whether to start based on the distance, and the preset start distance value is different from the first preset distance, or when it is an angle sensor, the angle threshold of the preset start condition is different from the first preset distance.
[0071] In a specific embodiment, it is determined whether the posture data meets the posture value condition. Within the time value, when the intelligent scanning device is in an upward posture and the inclination angle of the intelligent scanning device in the Z-axis direction is within a preset angle range, it is determined that the posture data meets the posture value condition.
[0072] The attitude value condition includes the conditions satisfied by the tilt angle of the intelligent scanning device in the Z-axis direction when the intelligent scanning device is in an upward attitude within the time value, for example, the preset angle range is -90°-90°. The upward attitude refers to the tilted attitude of the intelligent scanning device with the front end facing downward and the rear end facing upward.
[0073] According to the intelligent scanning device of the embodiment of the present application, the multiple captured images are screened and identified to determine the target scanning content, including: based on the images captured by the camera module in the low-power shooting mode, the multiple captured images are corrected and processed to determine the target scanning content.
[0074] In detail, when the smart scanning device meets the preset startup conditions, the camera module is initialized to capture images in low power consumption mode and then cached or stored as a supplementary image set after the smart scanning device is started. After the smart scanning device is started in response to a scanning trigger signal, when screening and identifying the multiple captured images, if a correlation matching is performed on the contents contained in the multiple identified images and it is found that the correlation of the contents contained in the multiple identified images is higher than the correlation threshold, the content protected by the images in the supplementary image set is identified as a supplement, and the content subsequently acquired by the camera module is improved, thereby improving the recognition intelligence of text content such as long words, long phrases or sentences.
[0075] According to the intelligent scanning device of the embodiment of the present application, the intelligent scanning device also includes a fill light source, which is arranged at the front end of the shell 10. After the main control component receives the scanning trigger signal, it controls the camera module to start collecting the image of the scanning medium, including: after the main control component receives the scanning trigger signal, it controls the fill light source to emit invisible light, and the main control component controls the camera module to start collecting the image of the scanning medium.
[0076] Specifically, the fill light source is arranged at the front end of the housing 10, for example, arranged around the opening 11, which can facilitate auxiliary lighting into the scanning window 112, thereby improving the lighting effect, and emitting the lighting light source onto the scanning medium is conducive to improving the brightness when the camera module collects images, thereby helping to improve the clarity and recognizability of the images collected by the intelligent scanning device. For example, when the intelligent scanning device is far away from the scanning medium, the main control component controls the fill light source to emit invisible light after receiving the scanning trigger signal, which helps to solve the problem of darkening of the image caused by the increase in the distance between the intelligent scanning device and the scanning medium, thereby expanding the image acquisition range while ensuring the clarity and recognizability of the image.
[0077] In some embodiments, increasing the illumination intensity of the fill light source may be achieved by increasing the luminous flux, or increasing the number of light-emitting components that simultaneously emit the fill light source.
[0078] The supplementary light source may include, for example, one or more of infrared light, far infrared light, and ultraviolet light.
[0079] like Figure 2-Figure 4 As shown, according to the intelligent scanning device of the embodiment of the present application, the opening 11 defines an observation window 111 and a scanning window 112 that are relatively arranged, and the intelligent scanning device also includes a transparent support member 60 that is clamped in the opening 11, and the two sides of the support member 60 are respectively opposite to the observation window 111 and the scanning window 112, and the support member 60 abuts against the first cross beam 12, and the support member 60 and the front end of the shell 10 jointly define a first installation groove, and the pressure sensing component 30 is embedded in the first installation groove.
[0080] In detail, the support member 60 is fixed to the housing 10 and abuts against the first crossbeam 12, so that the support member 60 increases the structural strength of the first crossbeam 12 and improves the structural strength of the front end of the housing 10 as a whole. The support member 60 is set to a transparent structure, so that light can penetrate into the scanning window 112, assist the image acquisition component to fill in light, and facilitate the user to observe the content framed in the scanning window 112 through the support member 60.
[0081] The support member 60 can be connected to the front end portion, rear end portion or side portion of the housing 10 located at the opening 11, and can be detachably connected or integrally formed, which is not limited in the present application. In one embodiment of the present application, the support member 60 is detachably connected to the housing 10.
[0082] The support member 60 and the front end of the housing 10 together define a first mounting groove, and the pressure sensing component 30 is embedded in the first mounting groove. The first mounting groove can be used to limit and fix the pressure sensing component 30.
[0083] The material of the support member 60 can be selected from a variety of different materials as needed, and the mechanical strength, transparency, durability, processing performance and other aspects of the material can be considered during selection. For example, glass can be selected, which has excellent optical transparency and scratch resistance, high hardness, and good chemical stability. Resin materials such as acrylic, polycarbonate (PC), polyurethane (TPU), and epoxy resin can also be selected.
[0084] In addition, the shape of the support member 60 can be set as needed, for example, it can be set to a three-dimensional structure with a cross section of a circle, an ellipse, a triangle, a pentagon, etc.
[0085] In some embodiments, the sensor assembly 40 includes a distance sensor, which is disposed in the first mounting groove and is electrically connected to the main control assembly. The distance sensor is disposed in the first mounting groove, and the distance between the distance sensor and the trigger assembly 50 is relatively close. When the intelligent scanning device contacts the scanning medium, the distance between the distance sensor and the scanning medium is closer, which is conducive to improving the detection accuracy. At the same time, the distance sensor is disposed in the first mounting groove, which can reasonably plan the positions of various components and improve the rationality of the structural setting.
[0086] like Figure 2-Figure 4 As shown, in some embodiments, a first beam 12 and a second beam 13 are respectively provided on the front and rear sides of the opening 11, and the support member 60 abuts against the first beam 12 and the second beam 13 at the same time, and a main control component is fixed to the side of the second beam 13 facing away from the support member 60.
[0087] In detail, the support member 60 is abutted against the first beam 12 and the second beam 13 at the same time. The second beam 13 can cooperate with the first beam 12 to limit and position the support member 60. The second beam 13 is used to enhance the supporting force of the support member 60 on the first beam 12, thereby jointly enhancing the structural strength of the first beam 12 and reinforcing the structural strength of the front end of the shell 10.
[0088] The thickness of the first cross beam 12 and the second cross beam 13 can be set as required and can be substantially consistent with the thickness of the support member 60 .
[0089] like Figure 5 As shown, in some embodiments, a side of the support member 60 close to the scanning window 112 has a first convex surface 61 , and the first convex surface 61 protrudes toward a direction close to the scanning window 112 .
[0090] Specifically, the support member 60 has the effect of a magnifying glass. On the one hand, it is convenient to gather light to the scanning window 112, thereby improving the illumination level of the fill light source. On the other hand, when the user observes the content framed in the scanning window 112 through the observation window 111, the content framed on the scanning medium is magnified, which is helpful for the user to determine whether the selected content is accurate.
[0091] The protruding curvature of the first convex surface 61 can be set as needed. If it is too large, the overall volume of the intelligent scanning device will be increased, while if it is too small, the magnification effect will be poor. Therefore, a suitable curvature needs to be set.
[0092] In some embodiments, a side of the support member 60 close to the observation window 111 has a second convex surface, and the second convex surface protrudes toward a direction close to the observation window 111 .
[0093] In this way, the support member 60 has the effect of a magnifying glass. On the one hand, it is convenient to gather light to the scanning window 112, thereby improving the illumination level of the fill light source. On the other hand, when the user observes the content framed in the scanning window 112 through the observation window 111, the content framed on the scanning medium is magnified, which is helpful for the user to determine whether the selected content is accurate.
[0094] Among them, the protruding curvature of the second convex surface can be set as needed. If it is too large, it will hinder the camera module from acquiring images, while if it is too small, the magnification effect will be poor. Therefore, a suitable curvature needs to be set.
[0095] like Figure 4 and Figure 5 As shown, in some embodiments, a transparent first cover plate 91 is provided at the observation window 111 , and a transparent second cover plate 92 is provided at the scanning window 112 .
[0096] The transparent first cover plate 91 can facilitate the penetration of light, thereby providing light illumination for the image acquisition component of the smart scanning pen so as to identify the document to be scanned, and facilitating the user to observe the content framed in the scanning window 112 through the support block.
[0097] The first cover plate 91 can be made of resin materials such as glass, acrylic, polycarbonate (PC), polyurethane (TPU), and epoxy resin.
[0098] The scanning window 112 is used to select the content to be identified. The second cover plate 92 can be used to close the intelligent scanning device at the observation window 111, which is dustproof and waterproof. The second cover plate 92 is set as a transparent structure, which is conducive to the image acquisition component to obtain the content and cooperate with the observation window 111 to provide auxiliary lighting for the image acquisition component.
[0099] The second cover plate 92 can be made of resin materials such as glass, acrylic, polycarbonate (PC), polyurethane (TPU), and epoxy resin.
[0100] In some embodiments, a first limiting groove and a second limiting groove are provided on the side wall of the opening 11, and a first limiting portion and a second limiting portion are provided on the support member 60. The first limiting portion is clamped in the first limiting groove, and the second limiting portion is clamped in the second limiting groove. The first limiting portion and the second limiting portion have different shapes and / or sizes.
[0101] Specifically, the side wall of the opening 11 is provided with a first limiting groove and a second limiting groove, and the support member 60 is provided with a first limiting portion and a second limiting portion. The first limiting portion and the first limiting groove are clamped together, and the second limiting portion and the second limiting groove are clamped together, thereby increasing the contact area between the support member 60 and the opening 11. The first limiting portion and the second limiting portion have different shapes and / or sizes, which can reduce the possibility of shaking in the assembly between the first limiting portion and the first limiting groove and the second limiting portion and the second limiting groove caused by processing errors, improve the stability between the support member 60 and the opening 11 after assembly, and also improve the reliability of the intelligent scanning device when it is hit. In addition, when the support member 60 is a plastic part, setting the first limiting portion and the second limiting portion to have different shapes and / or sizes can also reduce the processing difficulty during injection molding.
[0102] It should be noted that the first limiting portion and the second limiting portion have different shapes and / or sizes, which means that, in some embodiments, the first limiting portion and the second limiting portion have different shapes; in some embodiments, the first limiting portion and the second limiting portion have different sizes; in some embodiments, the first limiting portion and the second limiting portion have different shapes and sizes.
[0103] like Figure 2 and Figure 4As shown, in some embodiments, a deformable member 70 is sandwiched between the trigger assembly 50 and the pressure sensing assembly 30 .
[0104] The deformable member 70 is sandwiched between the trigger portion 513 and the pressure sensing component 30. The deformable member 70 is used to transmit the force acting on the trigger component 50 to the pressure sensing component 30. While transmitting the force, the deformable member 70 can absorb the force by deformation, thereby buffering the effect of the trigger component 50 on the pressure sensing component 30, so that the pressure sensing component 30 can sense a larger force without being damaged.
[0105] It is understandable that as the trigger component 50 increases in size, the force acting on the pressure sensing component 30 will increase. Therefore, as the trigger component 50 increases in size, the deformable member 70 is used to transmit the force acting on the trigger component 50 to the pressure sensing component 30. While transmitting the force, the deformable member 70 can utilize deformation to absorb the force, thereby buffering the effect of the trigger component 50 on the pressure sensing component 30, allowing the pressure sensing component 30 to sense a greater force without being damaged.
[0106] In addition, the deformable member 70 also has the function of resetting the trigger assembly 50. After the force acting on the trigger assembly 50 disappears, the deformable member 70 is reset and drives the trigger assembly 50 to reset.
[0107] like Figure 2 As shown, in some embodiments, a third limiting portion 65 is provided on a side of the support member 60 opposite to the first cross beam 12, a third limiting groove is provided on the deformable member 70, and the third limiting portion 65 is engaged with the third limiting groove.
[0108] Specifically, since the size of the deformable member 70 is relatively large, the third limiting portion 65 and the third limiting groove are used for limiting and positioning, thereby simplifying the difficulty of aligning the deformable member 70 when it is installed on the support member 60. At the same time, by using the cooperation between the third limiting portion 65 and the third limiting groove, when the trigger assembly 50 of the intelligent scanning device is forced to drive the deformable member 70 to deform, the positioning cooperation between the third limiting portion 65 and the third limiting groove can also prevent the deformable member 70 from being misaligned during the resetting process.
[0109] like Figure 2 and Figure 4 As shown, according to the intelligent scanning device of the embodiment of the present application, a through hole 121 connected to the opening 11 is provided on the first crossbeam 12, and the trigger component 50 includes a trigger member 51, and the trigger member 51 is inserted into the through hole 121. The trigger member 51 includes a main body 511, a connecting portion 512 and a trigger portion 513. The connecting portion 512 connects the main body 511 and the trigger portion 513. A sealing member 80 is sleeved on the connecting portion 512. At least part of the main body 511 is exposed outside the through hole 121 so as to abut against the scanning medium when in use. The trigger portion 513 faces the opening 11 and abuts against the pressure sensing component 30.
[0110] In detail, the trigger 51 includes a main body 511, at least part of which is located outside the housing 10, so that when the reading pen selects the document to be read, the main body 511 directly contacts the scanning medium, increasing the contact area between the reading pen and the paper surface, so that the reading pen is more evenly stressed when moving with the paper surface, and more stable when moving. The connecting part 512 is provided with a sealing member 80, which can block the gap between the trigger 51 and the through hole 121, prevent dust and water, and prevent impurities and water from passing through the gap to damage the pressure sensing component 30 and other parts.
[0111] like Figure 2 As shown, in some embodiments, the number of connecting parts 512 is two, the number of triggering parts 513 is two, the two triggering parts 513 correspond to the two connecting parts 512 one by one, and the relative interval between the main body 511 and the triggering part 513 defines a first avoidance groove 514, and the first avoidance groove 514 is located on the side where the two connecting parts 512 are away from each other, and part of the sealing member 80 is embedded in the first avoidance groove 514.
[0112] It can be understood that there are two trigger parts 513, and the two trigger parts 513 are arranged at intervals, which is conducive to the concentrated force on the deformable member 70, thereby improving the sensitivity of the pressure sensing component 30. By setting the first avoidance groove 514, the connection size between the main body 511 and the connecting part 512 and the connection size between the connecting part 512 and the trigger part 513 can be reduced. When the main body 511 is subjected to a force when abutting against the scanning medium, the stress can be concentrated and transmitted to the trigger part 513 through the connecting part 512, and then transmitted to the pressure sensing component 30 through the trigger part 513, so that the reaction when the force is transmitted to the pressure sensing component 30 is faster, thereby improving the sensitivity of the trigger member 51 to transmit the force, and the vacant first avoidance groove 514 can also be used to clamp the seal 80, thereby improving the accuracy of the position and positioning of the seal 80 and avoiding misalignment or displacement.
[0113] like Figure 2 As shown, in some embodiments, the relative spacing between the main body portion 511 and the trigger portion 513 defines a second avoidance groove 515 , and the second avoidance groove 515 is located on a side where the two connecting portions 512 are close to each other.
[0114] In detail, by providing the second avoidance groove 515, the connection size between the main body 511 and the connecting part 512 and the connection size between the connecting part 512 and the trigger part 513 can be reduced. When the main body 511 is subjected to a force when abutting against the scanning medium, the stress can be concentrated and transmitted to the trigger part 513 through the connecting part 512, and then transmitted to the pressure sensing component 30 through the trigger part 513, so that the reaction when the force is transmitted to the pressure sensing component 30 is faster, thereby improving the sensitivity of the trigger member 51 to transmit the force.
[0115] like Figure 2 , Figure 7 and Figure 8 As shown, in some embodiments, a latching protrusion 516 is provided on the main body 511 , and the latching protrusion 516 is located between the two connecting portions 512 and is spaced apart from the connecting portions 512 on both sides, and a latching groove 71 is provided on the seal 80 , and the latching protrusion 516 is embedded in the latching groove 71 .
[0116] Specifically, a latching protrusion 516 is provided on the main body 511, and the latching protrusion 516 is located between the two connecting parts 512 and is spaced apart from the connecting parts 512 on both sides. A latching groove 71 is provided on the seal 80, and the position of the seal 80 can be further limited by utilizing the cooperation between the latching protrusion 516 and the latching groove 71. During multiple pressings of the trigger member 51, the seal 80 is always kept in place, thereby improving the sealing performance of the seal 80.
[0117] The cross-sectional dimensions of the protruding portion 516 include, but are not limited to, circular, square, triangular, and elliptical.
[0118] In addition, the number of the protruding portions 516 can be one or more, for example, two, three, four, five, etc.
[0119] like Figure 4 As shown, in some embodiments, a third avoidance groove 122 is provided on the first crossbeam 12 , and the third avoidance groove 122 is opposite to the pressure sensing component 30 so that a partial area of the first crossbeam 12 is spaced apart from the pressure sensing component 30 .
