Unless otherwise specified, the meaning of "a plurality" is two or more.
[0069] The following will further illustrate the technical solutions of the present application with reference to specific embodiments and the accompanying drawings.
[0070] See Figure 1 、 Figure 2 and Figure 3, the scanning pen 100 includes: a housing 1, a pen tip 2, and a scanning component 3. Among them, the housing 1 encloses to form a receiving cavity 10, and an opening 11 communicating with the receiving cavity 10 is provided on the housing 1. The pen tip 2 is reciprocally slidably arranged on the housing 1 along a first direction F1 ( Figure 3 the X-axis direction in), and the opening 11 is located on the movement track of the pen tip 2, so that the pen tip 2 can extend or retract into the receiving cavity 10 through the opening 11. When the pen tip 2 extends out of the receiving cavity 10, it is used to abut against the scanned item. The scanning component 3 is arranged on the housing 1, and the scanning component 3 is used to scan the scanned item.
[0071] In this embodiment, since the pen tip 2 is reciprocally slidably arranged on the housing 1 along the first direction F1, the opening 11 is located on the movement track of the pen tip 2, and the opening 11 communicates with the receiving cavity 10. Therefore, when the pen tip 2 reciprocally slides along the first direction F1, the purpose of making the pen tip 2 extend or retract into the receiving cavity 10 through the opening 11 can be achieved.
[0072] Based on this, when it is necessary to scan the scanned item through the scanning pen 100, first, the pen tip 2 can be slid along the negative direction of the first direction F1 ( Figure 3 the negative direction of the X-axis in), so that the pen tip 2 extends out of the receiving cavity 10 through the opening 11, that is, the pen tip 2 is in the extended state. Then, the pen tip 2 can be made to abut against the scanned item. Finally, the scanned item can be scanned through the scanning component 3. Thus, the purpose of scanning the scanned item through the scanning pen 100 is achieved.
[0073] After the scanning is completed, the pen tip 2 can be retracted into the receiving cavity 10 through the opening 11, that is, the pen tip 2 is in the retracted state.
[0074] It can be seen that for the scanning pen 100 provided in this embodiment, when it is necessary to scan the scanned item, the pen tip 2 can be made to extend out of the receiving cavity 10 through the opening 11, so that the pen tip 2 is in the extended state. After the scanning is completed, the pen tip 2 can be made to retract into the receiving cavity 10 through the opening 11, so that the pen tip 2 is in the retracted state. It can be understood that when the pen tip 2 is in the retracted state, the housing 1 can wrap the pen tip 2 around its periphery. Such a setting can avoid or reduce the situation that the pen tip 2 is damaged when the scanning pen 100 falls, and further can avoid the situation that the entire scanning pen 100 is scrapped.
[0075] In addition, when the pen tip 2 retracts into the receiving cavity 10, the volume of the entire scanning pen 100 can also be made relatively small. On the one hand, it is convenient for the storage of the scanning pen 100. On the other hand, the appearance of the scanning pen 100 can also be made simple. On the third hand, the holding angle of the scanning pen 100 by the user also becomes more diverse, and there is no need to deliberately avoid the pen tip 2 when holding the scanning pen 100, and the use experience is better.
[0076] In addition, when the pen tip 2 is retracted into the accommodation cavity 10, the appearance of the scanning pen 100 can be made substantially the same as that of ordinary electronic devices such as MP4s, so that the scanning pen 100 can be used as an ordinary MP4, thereby making the usage scenarios of the scanning pen 100 more diverse and rich.
[0077] It can be understood that when the scanning pen 100 is an electronic device such as an MP4, a screen can also be provided on the housing 1, and a battery, a main board, etc. can also be provided in the accommodation cavity 10. The structure of the scanning pen 100 is not limited in this embodiment.
[0078] Among them, the scanned document can be any possible learning material such as textbooks, tutoring materials, etc. The scanned document is not limited in this embodiment.
[0079] According to the above description, when the pen tip 2 is in the extended state, it means that the work of scanning the scanned document needs to be performed by the scanning pen 100. In order to enable the scanning pen 100 to immediately start the function of scanning the scanned document when the pen tip 2 is in the extended state, in some embodiments, refer to Figure 3 , the scanning pen 100 further includes: an induction component 7, the induction component 7 is electrically connected to the scanning component 3, the induction component 7 is used to detect whether the pen tip 2 is in the extended state or the retracted state, and the scanning component 3 is used to start scanning the scanned document when the pen tip 2 is in the extended state.
[0080] With such a setting, when the pen tip 2 changes from the retracted state to the extended state, it can be immediately detected by the induction component 7. In the case where the induction component 7 can detect whether the pen tip 2 is in the extended state or the retracted state, since the induction component 7 is electrically connected to the scanning component 3, the scanning component 3 can obtain the information of whether the pen tip 2 is in the extended state or the retracted state at this time from the induction component 7. Then, when the induction component 7 detects that the pen tip 2 is in the extended state, it can immediately automatically start the function of scanning the scanned document, and when the induction component 7 detects that the pen tip 2 is in the retracted state, it can immediately automatically turn off the function of scanning the scanned document, without the need for the user to manually start it, making the automation degree of the scanning pen 100 higher, and thus making the user experience better.
[0081] Among them, there are various implementation manners of the above induction component 7, as long as it can achieve the purpose of detecting whether the pen tip 2 is in the extended state or the retracted state, and this embodiment does not limit this. In one possible implementation manner, refer to Figure 3 and Figure 4 , the induction component 7 includes a magnetic part 71 and a Hall sensor 72. Among them, the Hall sensor 72 is electrically connected to the scanning component 3, the magnetic part 71 is arranged on the pen tip 2, and the Hall sensor 72 is arranged on the housing 1.
[0082] Since the magnetic member 71 is disposed on the pen tip 2 and the Hall sensor 72 is disposed on the housing 1, when the pen tip 2 reciprocally slides along the first direction F1 ( Figure 3 the X-axis direction in
[0083] ), causing the pen tip 2 to switch between the retracted state and the extended state, the distance between the magnetic member 71 and the Hall sensor 72 can be changed. As a result, the Hall sensor 72 can sense the change in the magnetic field of the magnetic member 71, and then it can detect whether the pen tip 2 is in the retracted state or the extended state based on the change in the magnetic field. Since the Hall sensor 72 is electrically connected to the scanning assembly 3, the scanning assembly 3 can obtain information about whether the pen tip 2 is in the extended state or the retracted state from the Hall sensor 72. Then, it can immediately automatically activate or deactivate the function of scanning the scanned object. Figure 4 Among them, the Hall sensor 72 being disposed on the housing 1 can be a direct setting or an indirect setting. For example, referring to
[0084] , the Hall sensor 72 can be disposed on the circuit board 31 of the scanning assembly 3, and then the circuit board 31 can be disposed on the housing 1, thereby achieving the purpose of disposing the Hall sensor 72 on the housing 1. This embodiment does not limit this.
[0085] In addition, the above-mentioned setting method where the magnetic member 71 is disposed on the pen tip 2 and the Hall sensor 72 is disposed on the housing 1 is just a possible setting method given in this embodiment. In other setting methods, the Hall sensor 72 can also be disposed on the pen tip 2 and the magnetic member 71 can be disposed on the housing 1. This embodiment does not limit this.
[0086] It should be noted that the above-mentioned magnetic member 71 can be a magnet or any other possible magnetic member. This embodiment does not limit the magnetic member 71.
[0087] In some embodiments, the above-mentioned scanning assembly 3 may include a camera, and the camera can be used to scan the information on the scanned object. To make the scanning effect of the scanning assembly 3 better, the scanning assembly 3 may further include a flash, and the flash can supplement light for the camera so that the camera can scan the scanned object more clearly.
[0088] Of course, the scanning assembly 3 may also include other possible components, as long as it can achieve the function of scanning the scanned object. This embodiment does not limit the scanning assembly 3. Figure 4 and Figure 5 , in order to make the pen tip 2 slide more smoothly along the first direction F1, in some embodiments, referring to
[0089] Since the guide rod 4 extends along the first direction F1 and is located within the accommodation cavity 10, and the pen tip 2 is provided with a guide hole 20, the pen tip 2 is slidably sleeved on the guide rod 4 along the first direction F1 through the guide hole 20. Therefore, under the guiding action of the guide rod 4, the pen tip 2 can slide more smoothly along the first direction F1.
[0090] That is to say, the pen tip 2 realizes the purpose of being slidably arranged on the housing 1 along the first direction F1 through the cooperation of the guide rod 4 and the guide hole 20. Of course, the pen tip 2 can also achieve the purpose of being slidably arranged on the housing 1 along the first direction F1 through other possible means. For example, it can be achieved by the cooperation of a guide rail and a slider to be slidably arranged on the housing 1 along the first direction F1. This embodiment does not limit this.
[0091] In order to make the guiding action of the guide rod 4 better, and thus make the pen tip 2 slide more smoothly along the first direction F1, refer to Figure 4 and Figure 5 , the number of the guide rods 4 and the number of the guide holes 20 can both be multiple, and the multiple guide rods 4 and the multiple guide holes 20 are arranged in one-to-one correspondence. With such an arrangement, the multiple guide rods 4 can jointly guide the pen tip 2, and the pen tip 2 can slide more smoothly along the first direction F1.
[0092] Specifically, the number of the guide rods 4 can be two. Of course, the number of the guide rods 4 can also be three or four, etc. This embodiment does not limit this.
[0093] Furthermore, in order to make the pen tip 2 slide more smoothly and stably along the first direction F1, in some embodiments, refer to Figure 4 , Figure 5 and Figure 6 , the housing 1 is provided with an extension part 12. The extension part 12 is located within the accommodation cavity 10. The extension part 12 is provided with a through hole 121 that penetrates the extension part 12 along the first direction F1. The through hole 121 is communicated with the opening 11, so that when the pen tip 2 reciprocally slides along the first direction F1, it can extend out of or contract into the accommodation cavity 10 through the through hole 121 and the opening 11.
[0094] Since the through hole 121 provided on the extension part 12 that penetrates the extension part 12 along the first direction F1 is communicated with the opening 11, the through hole 121 and the opening 11 can jointly guide the pen tip 2, making the pen tip 2 slide more smoothly and stably along the first direction F1.
[0095] It can be understood that, in order to ensure that the through hole 121 and the opening 11 can jointly guide the pen tip 2, the shapes of the through hole 121 and the opening 11 can match the shape of the pen tip 2. In this way, the channel formed jointly by the through hole 121 and the opening 11 is longer than the channel formed by the opening 11. Therefore, the guiding effect on the pen tip 2 is better, and further, when the pen tip 2 slides along the first direction F1, it can be smoother and more stable.
[0096] See Figure 4 , Figure 6 and Figure 7 , in order to avoid that when the pen tip 2 slides and contracts into the accommodation cavity 10 along the positive direction of the first direction F1 ( Figure 7 the positive direction of the X-axis in Figure 7 ), the pen tip 2 slides out of the opening 11 and detaches from the housing 1, resulting in that when the pen tip 2 slides along the negative direction of the first direction F1 ( Figure 7 the negative direction of the X-axis in
[0097] ), the position of the pen tip 2 and the opening 11 is not aligned, causing the pen tip 2 to be blocked by the housing 1 and unable to extend out of the accommodation cavity 10 through the opening 11. In some embodiments, when the pen tip 2 contracts into the accommodation cavity 10, a part of the structure of the pen tip 2 can be located within the through hole 121. In this way, since the through hole 121 is communicated with the opening 11, the through hole 121 can play a guiding role on the pen tip 2, enabling the pen tip 2 to very smoothly extend out of the accommodation cavity 10 through the opening 11 under the guidance of the through hole 121, and the situation that the pen tip 2 is blocked by the housing 1 and unable to extend out of the accommodation cavity 10 through the opening 11 due to the misalignment of the position of the pen tip 2 and the opening 11 can be avoided.
[0097] In order to avoid that when the pen tip 2 reciprocally slides along the first direction F1, the sliding stroke of the pen tip 2 is too large, resulting in the whole pen tip 2 sliding out of the accommodation cavity 10 through the opening 11 and detaching from the housing 1. In some embodiments, see Figure 5 and Figure 8 , the pen tip 2 includes: a blocking portion 21 and a pen head portion 22. Among them, the blocking portion 21 is reciprocally slidably arranged on the housing 1 along the first direction F1 and is located within the accommodation cavity 10. The projection of the blocking portion 21 on the housing 1 along the first direction F1 exceeds the opening 11. The pen head portion 22 is connected to the blocking portion 21. When the blocking portion 21 reciprocally slides along the first direction F1, it can drive the pen head portion 22 to extend out of or contract into the accommodation cavity 10 through the opening 11. When the pen head portion 22 extends out of the accommodation cavity 10, it is used to abut against the scanned object.
[0098] Since the projection of the blocking portion 21 on the housing 1 along the first direction F1 exceeds the opening 11, in this way, it can be made that the contour of the blocking portion 21 exceeds the opening 11. In this way, when the pen head portion 22 moves along the negative direction of the first direction F1 ( Figure 5When moving in the negative direction of the X-axis (in the negative direction of the first direction F1), as the moving stroke of the pen tip 22 increases, the blocking portion 21 will abut against the housing 1, preventing the pen tip 22 from continuing to move in the negative direction of the first direction F1. The blocking portion 21 can play a role in limiting the position, thereby avoiding the situation that the overall pen tip 2 slides out of the accommodating cavity 10 through the opening 11 and detaches from the housing 1 due to an excessive sliding stroke of the pen tip 2.
[0099] To make the pen tip 22 abut more stably against the scanned object, refer to Figure 8 The number of the pen tips 22 can be two. When the number of the pen tips 22 is two, more fulcrums can be formed between the pen tip 2 and the scanned object, and thus the pen tip 22 can abut more stably against the scanned object. Of course, the number of the pen tips 22 can also be other possible numbers. For example, the number of the pen tips 22 can also be three or four, etc. The present embodiment does not limit the number of the pen tips 22 either.
[0100] In some embodiments, refer to Figure 5 the scanning pen 100 further includes: a driving component 5, and the driving component 5 is configured to drive the pen tip 2 to slide in the negative direction of the first direction F1 ( Figure 5 in the negative direction of the X-axis in the figure), so that the pen tip 2 extends out of the accommodating cavity 10 through the opening 11. When the pen tip 2 is subjected to an external force in the positive direction of the first direction F1 ( Figure 5 in the positive direction of the X-axis in the figure), the pen tip 2 can slide in the positive direction of the first direction F1, so that the pen tip 2 contracts into the accommodating cavity 10 through the opening 11.
[0101] By providing the driving component 5, the pen tip 2 can be automatically extended out of the accommodating cavity 10 without manually pulling the pen tip 2 out of the accommodating cavity 10 by a person. Therefore, the degree of automation is higher.
[0102] After the scanning is completed, an external force in the positive direction of the first direction F1 ( Figure 5 in the positive direction of the X-axis in the figure) can be applied to the pen tip 2. When the pen tip 2 is subjected to an external force in the positive direction of the first direction F1, the pen tip 2 can slide in the positive direction of the first direction F1, so that the pen tip 2 contracts into the accommodating cavity 10.
[0103] There are multiple implementation manners for the above-mentioned driving component 5. In one possible implementation manner, refer to Figure 5 the driving component 5 includes: a first elastic member 51. The first elastic member 51 is located in the accommodating cavity 10 and is respectively connected to the pen tip 2 and the housing 1. The first elastic member 51 is configured to provide an elastic force for driving the pen tip 2 to slide in the negative direction of the first direction F1 ( Figure 5 in the negative direction of the X-axis in the figure).
[0104] Since the first elastic member 51 can use its own elastic force to provide a driving force for the pen tip 2 to slide in the negative direction of the first direction F1, the implementation method is simple and the cost is low. Therefore, the cost of the driving assembly 5 can be reduced. Of course, the driving assembly 5 can also be other possible structures, as long as it can provide a force for the pen tip 2 to slide in the negative direction of the first direction F1 ( Figure 5 the negative direction of the X-axis in the figure), this embodiment does not limit the specific structure of the driving assembly 5.
[0105] It should be noted that the above-mentioned first elastic member 51 can be a spring or any other possible elastic member, and this embodiment does not limit the first elastic member 51. When the first elastic member 51 is a spring, in some embodiments, the spring can be sleeved on the guide rod 4. In this way, the guide rod 4 can play a guiding role for the spring, and the situation that the spring topples during compression can be avoided.
[0106] In order to flexibly control the pen tip 2 to stop or continue to slide in the first direction F1, in some embodiments, refer to Figure 5 and Figure 9 , the scanning pen 100 further includes: a locking assembly 6, and the locking assembly 6 is used to lock or unlock the pen tip 2 so that the pen tip 2 can be stationary or continue to slide relative to the housing 1.
[0107] By setting the locking assembly 6, the pen tip 2 can be flexibly locked or unlocked, and the situation that the pen tip 2 accidentally retracts into the accommodating cavity 10 due to external forces or other reasons when the pen tip 2 is in the extended state or accidentally extends out of the accommodating cavity 10 when the pen tip 2 is in the retracted state can be avoided, making the use experience of the scanning pen 100 better.
[0108] Among them, there are various implementation methods for the above-mentioned locking assembly 6. In one possible implementation method, refer to Figure 9 and Figure 10 , the locking assembly 6 includes: a gear bar 61 and a locking member 62. Among them, the gear bar 61 is connected to the pen tip 2 and is located in the accommodating cavity 10. A stop portion 611 is provided on the gear bar 61. The locking member 62 includes a fastening portion 621 that matches the stop portion 611. The fastening portion 621 is reciprocally slidably disposed on the housing 1 along the second direction F2 ( Figure 10 the Z-axis direction in the figure) and is located in the accommodating cavity 10. Among them, the second direction F2 is different from the first direction F1, and the movement trajectory of the stop portion 611 intersects with the movement trajectory of the fastening portion 621, so that the fastening portion 621 can be fastened to or separated from the stop portion 611.
[0109] Since the fastening portion 621 is reciprocally slidably disposed in the housing 1 along the second direction F2 and is located within the accommodation cavity 10, the second direction F2 is different from the first direction F1 and there is an intersection between the movement locus of the stop portion 611 and the movement locus of the fastening portion 621. Therefore, when the fastening portion 621 moves along the second direction F2 towards the stop portion 611, the fastening portion 621 can be fastened to the stop portion 611. In this way, the fastening portion 621 can block the stop portion 611 from continuing to slide along the first direction F1, thereby achieving the purpose of controlling the pen tip 2 to stop sliding along the first direction F1. When the fastening portion 621 moves along the second direction F2 away from the stop portion 611, the fastening portion 621 can be disengaged from the stop portion 611. In this way, the fastening portion 621 can stop blocking the stop portion 611 from continuing to slide along the first direction F1, allowing the stop portion 611 to continue to slide along the first direction F1, and further achieving the purpose of controlling the pen tip 2 to continue to slide along the first direction F1.
[0110] Among them, referring to Figure 10 , the above-mentioned stop portion 611 can be a groove, and the above-mentioned fastening portion 621 can be a protrusion matching the shape of the stop portion 611. In this way, when the protrusion is fastened to or disengaged from the groove, the purpose of flexibly locking or unlocking the sliding of the pen tip 2 along the first direction F1 can be achieved.
[0111] Of course, the stop portion 611 and the fastening portion 621 can also be other possible structures, and this embodiment does not limit this.
[0112] The above-mentioned second direction F2 and the first direction F1 can be perpendicular. Of course, there can also be other possible angles between the second direction F2 and the first direction F1, and this embodiment does not limit this.
[0113] In order to flexibly control the position where the pen tip 2 stops when sliding along the first direction F1, in some embodiments, referring to Figure 10 , the number of the stop portions 611 is multiple, and the multiple stop portions 611 are arranged at intervals along the first direction F1 on the gear bar 61, and the fastening portion 621 can be fastened to any one of the multiple stop portions 611.
[0114] By arranging the multiple stop portions 611 at intervals along the first direction F1 on the gear bar 61 and making the fastening portion 621 be fastened to any one of the multiple stop portions 611, the position where the pen tip 2 stops when sliding along the first direction F1 can be flexibly controlled, and further the length of the pen tip 2 extending out of the accommodation cavity 10 along the first direction F1 can be flexibly adjusted, thereby making the use experience of the scanning pen 100 better.
[0115] In some embodiments, referring to Figure 10 , Figure 11 and Figure 12, the locking member 62 further includes: a pressing portion 622 and a connecting portion 623. Among them, a pressing opening 13 matching the shape of the pressing portion 622 is provided on the housing 1, and at least part of the structure of the pressing portion 622 is exposed from the accommodating cavity 10 through the pressing opening 13. The connecting portion 623 is located between the pressing portion 622 and the fastening portion 621 and is connected to the pressing portion 622 and the fastening portion 621 respectively. When the pressing portion 622 is subjected to a pressing force along the second direction F2 ( Figure 10 in the Z-axis direction in
[0116] ), it can drive the fastening portion 621 to reciprocally slide along the second direction F2. Figure 10 Since at least part of the structure of the pressing portion 622 is exposed from the accommodating cavity 10 through the pressing opening 13, therefore, the user can press the pressing portion 622 outside the accommodating cavity 10, so that the pressing portion 622 is subjected to a pressing force along the second direction F2 (
[0117] in the Z-axis direction in
[0118] ), and then the pressing portion 622 slides along the second direction F2. When the pressing portion 622 slides along the second direction F2, since the connecting portion 623 is located between the pressing portion 622 and the fastening portion 621 and is connected to the pressing portion 622 and the fastening portion 621 respectively, it can drive the fastening portion 621 to slide along the second direction F2, and then the purpose of making the fastening portion 621 fasten or disengage from the stopping portion 611 can be achieved. Figure 10 It can be seen that the purpose of making the fastening portion 621 fasten or disengage from the stopping portion 611 can be achieved by pressing, and the implementation method is very simple.
[0119] In some embodiments, referring to
[0120]
[0121] Figure 10 Figure 13 Figure 10 and Figure 13, the locking assembly 6 further includes: a seat body 64, the seat body 64 is disposed on the housing 1, covers the pressing portion 622 and has a gap 640 between the seat body 64 and the pressing portion 622. The second elastic member 63 is located in the gap 640 and is respectively connected to the pressing portion 622 and the seat body 64. A first guiding groove 641 extending along the first direction F1 ( Figure 13 the X-axis direction in Figure 13 ) is provided on the seat body 64. The gear bar 61 is slidably disposed in the first guiding groove 641 along the first direction F1; a second guiding groove 642 extending along the second direction F2 ( the Z-axis direction in
[0122] ) is further provided on the seat body 64. The second guiding groove 642 intersects with the first guiding groove 641. The connecting portion 623 is slidably disposed in the second guiding groove 642 along the second direction F2. An avoidance opening 6231 penetrating the connecting portion 623 along the first direction F1 is provided on the connecting portion 623 for the gear bar 61 to pass through along the first direction F1.
[0123] In addition, referring to Figure 10 and Figure 12 , since the connecting portion 623 is provided with an avoidance opening 6231 penetrating the connecting portion 623 along the first direction F1, the gear bar 61 can pass through the avoidance opening 6231 when sliding along the first direction F1. Therefore, when the gear bar 61 penetrates through the avoidance opening 6231 along the first direction F1, the fastening portion 621 can straddle the gear bar 61. In this way, when pressing the pressing portion 622 along the positive direction of the second direction F2 ( Figure 10 the positive direction of the Z-axis in
[0124] ), the pressing portion 622 will drive the fastening portion 621 to move away from the stop portion 611, and the second elastic member 63 will be compressed, so that the fastening portion 621 is disengaged from the stop portion 611. In this way, the pen tip 2 can slide out or retract into the accommodation cavity 10 along the first direction F1, achieving the purpose of unlocking the sliding of the pen tip 2 along the first direction F1. Figure 10 When the pressing of the pressing portion 622 stops, the second elastic member 63 will push the pressing portion 622 towards the negative direction of the second direction F2 (Sliding in the negative direction of the Z-axis, the fastening portion 621 is driven to move towards the stop portion 611, so that the fastening portion 621 is fastened to the stop portion 611, achieving the purpose of locking the sliding of the pen tip 2 along the first direction F1.
[0125] Among them, the second elastic member 63 can be a spring, and the number can be four or other possible numbers. This embodiment does not limit the second elastic member 63.
