The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

Furthermore, the terms "first," "second," and the like, are used primarily to distinguish between different devices, elements, or components (the particular species and configurations may be the same or different), and are not used to indicate or imply the relative importance and number of devices, elements, or components indicated. Unless otherwise indicated, the meaning of "a plurality" is two or more.

The embodiment of the application provides a scanning pen 01. As shown in fig. 1, the scanning pen 01 may have a length direction, a width direction, and a thickness direction. For convenience of explanation, the following embodiment will use the X direction as the length direction of the pen 01, the Y direction as the width direction of the pen 01, and the Z direction as the thickness direction of the pen 01. For example, the outline of the scanning pen 01 may be rectangular, the direction in which the long side is located may be the length direction of the scanning pen 01, and the direction in which the short side is located may be the width direction of the scanning pen 01. Of course, the scanning pen 01 may be provided in a square or oval shape. The specific shape of the scanning pen 01 is not particularly limited in the embodiment of the present application.

As shown in fig. 2, the scanning pen 01 may include a host 10, a scanning assembly 20 (shown in fig. 2), and a display screen 30. The host 10 may have oppositely disposed first and second surfaces 10a, 10b (shown in fig. 2). The host 10 is rotatably coupled to the scanning assembly 20. The scanning assembly 20 can be stored on the second surface 10b of the host 10 or extend out of the second surface 10b in the X direction of the host 10, the scanning assembly 20 is in a storage state, and the overall size of the scanning pen 01 can be reduced when the scanning assembly 20 is in the storage state, so that the scanning pen 01 is convenient to carry.

As an example, as shown in fig. 3, the host 10 may include a host housing 11, the host housing 11 may include a first housing 101 and a second housing 102 connected to each other, the first surface 10a may be disposed on the first housing 101, and the second surface 10b may be disposed on the second housing 102. The second housing 102 may include a slot bottom plate 11a and a slot side wall 11b, and the slot bottom plate 11a and the slot side wall 11b may enclose a receiving slot 11c, where the receiving slot 11c is located outside the second housing 102. When the scanning assembly 20 rotates relative to the host 10 and expands to the expanded state, the surface of the scanning assembly 20 may abut against the groove bottom plate 11a to limit the scanning assembly 20 from rotating continuously, thereby limiting the expanding angle of the scanning assembly 20.

As shown in fig. 1 and 4, the display screen 30 may be disposed on the first surface 10a of the host 10 and electrically connected to the host 10. The display screen 30 may cover the entire first surface 10a of the host 10, that is, in the XY plane, the area of the display screen 30 may be the same as that of the host 10, so that the display area may be increased.

As shown in fig. 5, the scanning pen 01 may further include a rotating shaft assembly 100, and the host computer 10 and the scanning assembly 20 may rotate around the rotating shaft assembly 100, so that the scanning assembly 20 may be folded to a storage state with respect to the host computer 10. Or, to a deployed state.

Specifically, as shown in fig. 5, the main body housing 11 (only a portion of which is shown in the drawing) may have a main body cavity, which may be formed by connecting the first housing 101 (shown in fig. 3) and the second housing 102 (shown in fig. 3). The first housing 101 and the second housing 102 may be fastened, adhered, screwed, or the like. The connection manner of the first housing 101 and the second housing 102 is not particularly limited in the embodiment of the present application. The scan assembly 20 (shown in fig. 5) may include a scan housing 21 (only a portion of which is shown), and the scan housing 21 may have a scan cavity 22. The spindle assembly 100 may include a first spindle 110 and a second spindle 120 located on an a-a axis. The first and second rotating shafts 110 and 120 may be installed in the scan cavity 22 at both ends of the scan cavity 22 along the a-a axis such that one ends of the main body housing 11 and the scan housing 21 may be hinged through the first and second rotating shafts 110 and 120. Thereby allowing the host 10 and the scan assembly 20 to be rotated relative to each other about the rotation axis assembly 100.

In some embodiments, as shown in fig. 6, the second rotating shaft 120 may include a shaft sleeve 122 and a first connecting member 123 connected to each other, and the first connecting member 123 may be disposed at one end of the shaft sleeve 122 for connection with the scan housing 21, and the other end of the shaft sleeve 122 may be rotatably connected with the main housing 11. Of course, the second shaft 120 may be directly adhered to the scan housing 21 or integrally formed as a separate component. The specific structure of the second rotating shaft 120 and the connection manner between the second rotating shaft 120 and the scan housing 21 are not particularly limited in the embodiment of the present application.

Along the X direction, one end of the host 10 may be rotatably connected to one end of the scan assembly 20 through the rotation shaft assembly 100, so that the host 10 and the scan assembly 20 may rotate with each other, and the scan assembly 20 may be rotatably folded and stored in the storage groove 11c, so that the scan assembly 20 is in a storage state. The surface of the folded scanning assembly 20 facing away from the host 10 may be flush with the second surface 10b to maintain the alignment of the scanner 01. The scanning assembly 20 is in the storage state, and the overall dimension of the scanning pen 01 can be reduced in the storage state, so that the scanning pen 01 is convenient to carry, and the service efficiency of the scanning pen is improved.

To implement the scanning function of the scanning pen, as shown in fig. 3, the scanning assembly 20 may include a scanning window 201, the scanning window 201 may be disposed at an end of the scanning assembly 20 remote from the host computer 10, and the scanning window 201 may face the same side of the scanning pen 01 as the second surface 10b when the scanning pen 01 is unfolded. Thus, when the user holds the scanning pen 01, the scanning window 201 and the display screen 30 (shown in fig. 1) are opposite to each other, so that the display screen 30 faces the user side when the scanning window 201 faces the scanned object, and the user can perform video learning while scanning. Meanwhile, when the scanning pen 01 is folded, the scanning window 201 can be stored in the storage groove 11c, so as to prevent the scanning window 201 from colliding, scratching or entering dust.

As shown in fig. 7, the scanning pen 01 further includes a rotation angle detecting element 40, and the rotation angle detecting element 40 may be disposed on at least one of the host 10, the scanning assembly 20, or the rotating shaft assembly 100, and an output value of the rotation angle detecting element 40 is used to determine an angle between the host 10 and the scanning assembly 20, so that it may be determined that the scanning assembly 20 is in a storage state or an unfolding state with respect to the host 10.

Illustratively, the rotation angle detecting element 40 may be a magnetic induction sensor, which may measure the magnetic field strength, one magnetic member may be provided on one of the host computer 10 or the scanning assembly 20, and the rotation angle detecting element 40 may be provided on the other of the host computer 10 or the scanning assembly 20. The rotation angle detecting element 40 can measure the change in the magnetic field intensity when the scanning unit 20 is switched between the unfolded state and the stored state, so that the scanning pen 01 can determine the angle between the main body 10 and the scanning unit 20. Or, the rotation angle detecting element can be a rotary potentiometer, the rotation angle detecting element can be arranged on the rotating shaft assembly, and the rotation angle detecting element can measure the rotation parameter of the rotating shaft assembly, so that the scanning pen can determine the angle between the host machine and the scanning assembly. Or, the rotation angle detecting element can be a multi-axis sensor, at this time, the rotation angle detecting element can be simultaneously arranged on the host machine and the scanning component, when the scanning component rotates relative to the host machine, the acceleration value and the gyroscope angle value respectively output by the rotation angle detecting element on the host machine and the scanning component are different, so that the scanning pen can determine the angle between the host machine and the scanning component.

It will be appreciated that the scanning pen 01 of the embodiments of the present application includes a host 10 and a scanning assembly 20. Therefore, the scanning pen 01 of the embodiment of the present application may have various operation modes. Illustratively, the scanning assembly 20 is in the storage state, and the scanning pen 01 can independently have a play mode of the host 10, so as to meet the use requirement of the user on the large screen in the learning scene. The scanning component 20 is in an unfolding state, and the scanning pen 01 can also have a playing mode of the host 10 and a scanning mode of the scanning component 20 at the same time, so as to meet the use requirement that a user can scan target content by using the scanning component 20 and play video or images associated with the target content through the host 10. The embodiments of the present application do not particularly limit the various operation modes that the scanning pen 01 can have.

Since the rotation angle detecting element 40 capable of detecting the rotation angle between the host 10 and the scanning component 20 is arranged on the scanning pen 01, the scanning pen 01 can determine the rotation angle between the host 10 and the scanning component 20 through the output value of the rotation angle detecting element 40, and can determine that the scanning component 20 is in an unfolding state or a storage state, so that the scanning pen 01 can quickly read into a working mode corresponding to the rotation angle, and can be switched among multiple working modes according to the rotation condition of the scanning component 20. Therefore, compared with the traditional scanning device which selects the working mode by pressing a key or triggering an icon, the method of rotating the scanning assembly 20 to enable the scanning pen 01 to enter the corresponding working mode can realize the rapid opening function of different working modes, thereby further improving the use efficiency of the scanning device.

Alternatively, as shown in FIG. 4, the width of the display screen 30 may be greater than the width of the scanning assembly 20 in the Y-direction. On the one hand, the larger the area of the display screen 30 arranged on the host 10 is, the more the user experience can be improved. On the other hand, the smaller the width of the scanner unit 20 is, the easier it is to be accommodated in the accommodation groove 11c (shown in fig. 3), and the holding feeling of the scanner pen 01 by the small-hand user can be satisfied.

On this basis, as shown in fig. 8, the scanning assembly 20 may have a stent state. When the scan assembly 20 is in the cradle state, the scan assembly 20 is positioned between the stowed and deployed states in the above-described embodiments. Meanwhile, in the stand state, the scan assembly 20 has a predetermined angle α with the host 10. For example, in the storage state, the preset angle α between the scan assembly 20 and the host 10 may be 0 °. In the deployed state, the preset angle α between the scan assembly 20 and the host 10 may be 180 °. Depending on factors such as different dimensions of the scanning pen 01, different weights of the host computer 10, different weights of the scanning assembly 20, etc., the preset angle α between the scanning assembly 20 and the host computer 10 may be 10 °, 15 °, 18 °, 20 °, 25 °, 30 °, 45 °, 60 °, 80 °, 120 ° etc. in the stand state. The embodiment of the present application does not specifically limit the specific preset angle α.

When the scanning pen 01 is in the storage state, the stand state, or the unfolded state, the rotation shaft assembly 100 may provide a certain holding force to the scanning assembly 20 in order to allow the scanning assembly 20 to be maintained in the storage state, the stand state, or the unfolded state. The retaining force means that the scanning assembly 20 can keep the scanning assembly 20 in a folded or unfolded state relative to the host 10 by the rotating shaft assembly 100 under the action of no external force; when a certain force is applied to the scan assembly 20, the scan assembly 20 can be kept in a folded or unfolded state with respect to the host 10 by the rotation shaft assembly 100.

Illustratively, the manner in which the spindle assembly 100 provides the retention force to the scan assembly 20 may be to provide a damping force by the concave wheel, cam and spring being pressed against each other, thereby providing a certain retention force to the scan assembly 20. The retaining force provided by the rotating shaft assembly to the scanning assembly can also be provided by using magnetic force between an electromagnet and a magnet piece of the rotating shaft assembly as damping force of the rotating shaft assembly, so that a certain retaining force of the scanning assembly is provided. The mode that the rotating shaft assembly provides the holding force for the scanning assembly can provide the holding force for the scanning assembly at a plurality of positions, so that the scanning assembly can maintain the current state at a plurality of positions, and the use requirements of a user on the scanning pen 01 under different use scenes are met.

The spindle assembly 100 provides a holding force for the scanning assembly 20, so that a user can rotate the scanning assembly 20 to a preset angle alpha when using the scanning pen 01, the scanning assembly 20 can be used as a bracket, and the host 10 is supported on a desktop through the scanning assembly 20, so that the user can watch target content played by the host 10. Of course, the spindle assembly 100 may be provided with a plurality of gear positions to form adjustable gear positions of the scan assembly 20 in different stand states. The number of gear steps by which the scanning assembly 20 rotates is not particularly limited in the present embodiment.

Alternatively, the host computer 10 and the scan assembly 20 may not only be rotated with each other by the rotation shaft assembly 100, but also the host computer 10 and the scan assembly 20 may be maintained in a folded or unfolded fixed position by the rotation shaft assembly 100. Of course, the function of maintaining the host 10 and the scanning assembly 20 in a fixed position may also be accomplished by a locking structure.

In order to maintain the folded state between the host 10 and the scan assembly 20, the above-described locking structure may include a first locking member 60 as one embodiment. As shown in fig. 2, the first locking member 60 may be provided at a long side of the main body 10. Of course, the first locking member 60 may be disposed at other positions of the host 10, and the specific position of the first locking member is not particularly limited in the embodiments of the present application. Correspondingly, as shown in fig. 9, a first locking groove 20b matched with the first locking member 60 may be provided on the scanning assembly 20. When the scanning pen 01 is folded, the host 10 and the scanning assembly 20 can be locked by matching the first locking piece 60 with the first locking groove 20b. Specifically, the first locking member 60 may be provided on the first housing 101.

When the scan assembly 20 is in the storage state, the scan assembly 20 may be locked on the host 10 by a locking structure to maintain the storage state of the scan assembly 20. The spindle assembly 100 applies a holding force to the scan assembly 20 that rotates away from the host 10, the scan assembly 20 having a tendency to pop up away from the host 10.

When the locking structure is unlocked, the rotating shaft assembly 100 applies a holding force to the scanning assembly 20, which rotates away from the host 10, so that the scanning assembly 20 rotates, a preset angle α (for example, 18 °) is maintained between the scanning assembly 20 and the host 10, and the scanning assembly 20 hovers at the preset angle α to maintain the stand state, so that the scanning assembly 20 can be used as a stand of the host 10, so that a user can watch target content played by the host 10 conveniently.

It can be understood that the output value of the rotation angle detecting element 40 may also be used to indicate that the scanning assembly 20 and the host 10 are in a stand state, by setting the range of the preset angle α, the scanning pen 01 may determine that the scanning assembly 20 is in a stand state relative to the host 10 according to the output value of the rotation angle detecting element 40, and when the scanning assembly 20 is flicked to the range of the preset angle α after unlocking, the scanning pen 01 quickly reads and enters into a working mode corresponding to the stand mode, thereby further enriching the scenes that the scanning pen 01 quickly enters into different working modes by rotating the scanning assembly 20.

In order to better illustrate the content of the embodiments of the present application, the following embodiments will take the rotation angle detecting element 40 as a hall sensor as an example, and describe in detail how the scanning pen 01 determines the rotation angle of the scanning assembly 20 according to the output value of the rotation angle detecting element 40, and how the scanning pen 01 automatically enters into different working modes.

The scanning pen 01 includes a controller, which may be implemented as at least one of a CPU (Central Processing Unit ), DSP (Digital Signal Processor, digital signal processor) or ASIC (Application Specific Integrated Circuits, application specific integrated circuit). The controller can be flexibly deployed, and can be arranged in the host 10 or the scanning assembly 20. The controller is electrically connected to the rotation angle detecting element 40 so that the controller can receive the output value of the rotation angle detecting element 40.

The rotation angle detecting element 40 may be disposed on one of the host computer 10 or the scanning assembly 20, and the other of the host computer 10 or the scanning assembly 20 may be provided with a magnetic member 50, and the magnetic member 50 may be a magnet. During the rotation of the scanning assembly 20, the distance between the rotation angle detecting element 40 and the magnetic member 50 is different along the thickness direction of the scanning pen 01, so that the magnetic flux received by the rotation angle detecting element 40 changes, and the output value of the rotation angle detecting element 40 changes.

The output value of the rotation angle detection element 40 may be a quantized value in mT (millitesla). The scanning pen 01 may be preset with a correspondence relationship between the output value of the rotation angle detecting element 40 and the rotation angle, and the correspondence relationship may be a monotonically increasing and decreasing curve as shown in fig. 10, or may be a monotonically increasing curve. The correspondence may be stored in a storage device of the scanning pen 01, and when the controller receives the output value output by the rotation angle detecting element 40, the correspondence may be called from the storage device, and the rotation angle of the scanning assembly 20 may be determined according to the correspondence.

As shown in table 1, when the output value output by the rotation angle detecting element 40 is-2.5975 mT, the corresponding rotation angle of the scanning assembly 20 is 0 °; when the output value output by the rotation angle detecting element 40 is-1.577 mT, the corresponding rotation angle of the scanning assembly 20 is 60 degrees; when the output value output by the rotation angle detecting element 40 is-29.9 mT, the corresponding rotation angle of the scanning assembly 20 is 170 degrees; when the output value of the rotation angle detecting element 40 is-33.57 mT, the corresponding rotation angle of the scanning assembly 20 is 180 °. Therefore, in the process of switching the scanning assembly 20 from the storage state to the unfolding state, the output value output by the rotation angle detecting element 40 is in a monotonic decreasing trend, the magnetic flux is in an increasing trend, and each output value corresponds to an angle, so that the rotation angle of the scanning assembly 20 can be accurately detected by the rotation angle detecting element 40. Of course, the output values output by the rotation angle detecting element 40 may be monotonically increasing curves, as long as each output value can be ensured to correspond to an angle.

As described above, the scanning pen 01 may include a plurality of operation modes, and the controller may set a plurality of control instructions, where each control instruction is associated with a range of rotation angles and an operation mode, and when the controller determines that the rotation angle of the scanning assembly 20 is within a range of rotation angles through the output value of the rotation angle detecting element 40, the controller executes the corresponding control instruction to enable the scanning pen 01 to enter the corresponding operation mode.

Alternatively, when the controller determines that the rotation angle of the scanning assembly 20 is in the first angle range through the output value of the rotation angle detecting element 40, the controller determines that the scanning assembly 20 is in the storage state, and the controller controls the scanning pen 01 to automatically enter the first operation mode of the plurality of operation modes. The first angular range may be 0 ° to 5 °, or the first angular range may be other angular ranges approaching 0 °.

The first mode of operation of the scanning pen 01 may include the host 10 being in a first play mode or standby mode, and the scanning assembly 20 being in a standby mode. Specifically, the standby mode of the host 10 may refer to a mode in which the host 10 is not awake, generally refers to a mode in which the display 30 on the host 10 is off, or a mode in which the display 30 may display time but does not perform other related operations. The standby mode of the scan assembly 20 may refer to a mode in which the scan function is not activated.

In the case that the controller determines that the rotation angle of the scan assembly 20 re-enters the first angle range from the other angle range, indicating that the host 10 has been activated before, the host 10 may also be in the first play mode, where the first play mode may include a desktop display mode, that is, displaying an icon of a first application program, which is an application program unrelated to the scan function, such as a word book, a hearing aid, etc., on the display screen 30, that matches the scan assembly 20 in the storage state, and when the user triggers the icon of the first application program, the host 10 may execute the corresponding application program.

Alternatively, in the case that the controller determines that the rotation angle of the scanning assembly 20 is in the second angle range through the output value of the rotation angle detecting element 40, the controller determines that the scanning assembly 20 is in the stand state, and the controller controls the scanning pen 01 to automatically enter the second operation mode of the plurality of operation modes. The second angle range, that is, the selected range of the preset angle α, may be 10 ° to 120 °. The second angle range is not particularly limited in the embodiment of the present application.

With the scanning pen 01 in the second mode of operation, the host 10 may enter the second play mode and the scanning assembly 20 is in the standby mode. The second play mode of the host 10 may be to play the first target content including any one or more of video, audio, or images.

As previously described, the stand state of the scanning assembly 20 may include a plurality of different hover positions, and after the scanning assembly 20 is unlocked by the locking structure, a first gear of the stand state may be reached, and the user may continue to rotate the scanning assembly 20 to other different hover positions. Accordingly, the second operation mode may also include a plurality of second sub-operation modes corresponding to a plurality of gear positions. In each second sub-mode of operation, the host 10 may be in a different second sub-play mode, i.e., the host 10 may play different first target content, and the scanning assembly 20 may remain in a standby state.

For example, when the controller determines that the rotation angle of the scan assembly 20 is between 10 ° and 30 °, the scan assembly 20 can be regarded as a first gear automatically reached after being unlocked, and the second sub-playing mode automatically entered by the controller controlling the host 10 can be an audio playing mode. The user may continue to rotate the scan assembly 20 to the next gear, and when the controller determines that the rotation angle of the scan assembly 20 is 31 ° to 60 °, the controller controls the host 10 to automatically enter the second sub-play mode, which may be a video play mode. The user may continue to rotate the scanning assembly 20 to the next gear, and when the controller determines that the rotation angle of the scanning assembly 20 is 61 ° to 90 °, the second sub-playing mode that can control the host computer 10 to automatically enter may be the album image displaying mode. When the controller determines that the rotation angle of the scanning assembly 20 is 91 ° to 120 °, the controller can control the host 10 to automatically enter the second sub-playing mode as the recommended mode of the display content. In this way, the second operation mode entered by the scanning pen 01 may have a richer mode selection scheme in the case that the scanning assembly 20 is in the stand mode after the scanning assembly 20 is unlocked by the locking structure.

Alternatively, in the case where the controller determines that the rotation angle of the scan assembly 20 is in the third angle range through the output value of the rotation angle detecting element 40, the controller determines that the scan assembly 20 is in the unfolded state, and the controller controls the scan pen 01 to automatically enter the third operation mode among the plurality of operation modes. The third angular range may be 170 ° to 180 °, or other angular range approaching 180 °.

With the scanning pen 01 in the third mode of operation, the host 10 may enter a third play mode and the scanning assembly 20 is in the scanning mode. The third play mode of the host 10 includes playing the second target content associated with the scanned content acquired by the scanning component 20.

For example, the second target content may be an analysis content of the scanned content, so that the scanning pen 01 can help the user to obtain the answer quickly, thereby improving learning efficiency and learning experience. Alternatively, the second target content may also be a result of modification to the scanned content. The correction results may include scores, errors, and the like.

It should be noted that, the controller not only can control the scanning pen 01 to enter a corresponding working mode, but also can control the scanning pen 01 to switch among a plurality of working modes.

Illustratively, when the locking structure is unlocked, the scan assembly 20 springs out to the stand state under the retaining force of rotation away from the host 10, and the spindle assembly 100 retains the scan structure in the stand state. The controller determines that the rotation angle changes from the first angle range to the second angle range, and switches the working mode of the scanning pen 01 from the first working mode to the second working mode, namely, the scanning pen 01 can be awakened from the standby mode and quickly enters the working mode corresponding to the bracket state.

In order to wake up the scanning pen 01 from the first operation mode to the second operation mode in time, when the rotation angle of the scanning assembly 20 reaches the first gear of the stand state, the rotation angle detecting element 40 may be set to output a first level signal to the controller, so that the controller switches the scanning pen 01 to the second operation mode in time.

In the case that the scanning assembly 20 rotates from the storage state to the unfolding state relative to the host 10 through the rotating shaft assembly 100, the controller determines that the rotation angle changes from the first angle range to the third angle range, and the controller switches the operation mode of the scanning pen 01 from the first operation mode to the third operation mode, so that the scanning pen 01 can be awakened from the standby mode to the scanning mode. Also, when the rotation angle of the scan assembly 20 reaches the unfolded state, the rotation angle detecting element 40 may be set to output a second level signal to the controller, so that the controller timely switches the scan pen 01 to the third operation mode.

In the case that the scan assembly 20 rotates from the stand state to the extended state relative to the host 10 through the rotation shaft assembly 100, the controller determines that the rotation angle changes from the second angle range to the third angle range, and the controller switches the operation mode of the scan pen 01 from the second operation mode to the third operation mode.

In this way, the controller establishes a correlation between the rotation angle of the scanning component 20 and a plurality of working modes, and controls the scanning pen 01 to enter a corresponding working mode according to the interval range where the rotation angle of the scanning component 20 is located, and the working mode of the scanning pen 01 can be switched among the plurality of working modes along with the rotation of the scanning component 20, which is different from the mode of switching the working modes of the electronic equipment by a key or an icon in the related art, so that the efficiency of the scanning pen 01 entering different working modes is further improved.

In order to further improve the detection accuracy and reliability of the rotation angle detecting element 40, the embodiment of the present application describes the specific form of the rotation angle detecting element 40 in detail below.

Specifically, the rotation angle detecting element 40 is a hall sensor that can receive the magnetic field generated by the magnetic member 50 and output different output values by different received magnetic fluxes. As shown in fig. 12, 13 and 14, with the scanning assembly 20 in the deployed state, the rotation angle detecting element 40 and the magnetic member 50 have a first distance therebetween in the thickness direction of the scanning pen 01; when the scanning assembly 20 rotates relative to the host 10 and the scanning assembly 20 is in the storage state, the rotation angle detecting element 40 and the magnetic member 50 have a second distance L2 along the thickness direction of the scanning pen 01, and the first distance L1 is smaller than the second distance L2.

That is, when the scan module 20 is in the storage state, the distance between the rotation angle detecting element 40 and the magnetic member 50 is large, so that the magnetic flux received by the rotation angle detecting element 40 is small, and when the scan module 20 is rotated relative to the main unit 10 and is in the unfolding state, the distance between the rotation angle detecting element 40 and the magnetic member 50 is small, so that the magnetic flux received by the rotation angle detecting element 40 is large.

In this way, in the process of switching the scanning assembly 20 from the storage state to the unfolding state, the magnetic flux received by the rotation angle detecting element 40 increases progressively, so that the detection of the rotation angle detecting element 40 on the rotation of the scanning assembly 20 to the unfolding state is ensured to be more timely and accurate, so that the controller can determine that the scanning assembly 20 is in the unfolding state according to the output value of the rotation angle detecting element 40 in time, so as to switch the scanning pen 01 from the first working mode to the third working mode in time, namely, when the user rotates the scanning assembly 20 to the unfolding state, the effect that the scanning pen 01 can be automatically and quickly awakened from the standby mode is achieved.

Alternatively, the first distance L1 may satisfy 1.1 mm.ltoreq.L1.ltoreq.1.7 mm. In particular, the first distance L1 may be 1.1mm, 1.2mm, 1.4mm, 1.6mm or 1.7mm. Obviously, the first distance L1 between the rotation angle detecting element 40 and the magnetic member 50 is smaller, so that the rotation angle detecting element 40 can receive a stronger magnetic field, thereby also reducing the size requirements for the magnetic member 50 and the rotation angle detecting element 40, so that both the rotation angle detecting element 40 and the magnetic member 50 can be further miniaturized.

Optionally, the second distance L2 satisfies 5.7 mm.ltoreq.l2.ltoreq.6.4 mm. In particular, the second distance L2 may be 5.7mm, 5.9mm, 6.1mm, 6.3mm or 6.4mm. The second distance L2 between the rotation angle detecting element 40 and the magnetic member 50 can ensure that the rotation angle detecting element 40 can receive the magnetic field of the magnetic member 50, and can further reduce the maximum distance between the rotation angle detecting element 40 and the magnetic member 50, so that the scanning pen 01 can be further miniaturized.

Based on the first distance L1 and the second distance L2 between the rotation angle detecting element 40 and the magnetic member 50, the thickness of the rotation angle detecting element 40 may be reduced to be less than or equal to 0.6mm, and the thickness of the magnetic member 50 may be reduced to be less than or equal to 0.6mm, thereby reducing the space occupation requirement of the rotation angle detecting element 40 and the magnetic member 50 on the scanning pen 01.

In an alternative embodiment, as shown in fig. 7 and 11 to 13, the rotation angle detecting element 40 is disposed on the host 10, the magnetic member 50 is disposed on the scanning assembly 20, the S pole of the magnetic member 50 faces the rotation angle detecting element 40 when the scanning assembly 20 is in the unfolded state, and the N pole of the magnetic member 50 faces the rotation angle detecting element 40 when the scanning assembly 20 is in the stored state.

Because the magnetic member 50 can turn over along with the synchronous rotation of the scanning assembly 20, the direction of the magnetic flux received by the rotation angle detecting element 40 changes, so that the output quantity of the rotation angle detecting element 40 monotonically decreases in the process of rotating the scanning assembly 20 from the storage state to the unfolding state, so that the controller can determine the rotation angle of the scanning assembly 20 based on the output value of the rotation angle detecting element 40, and under the condition that the scanning assembly 20 is in the unfolding state, the rotation angle detecting element 40 can obtain stronger magnetic flux, so that the rotation angle detecting element 40 has a more accurate detection result on the unfolding state of the scanning assembly 20.

In combination with the above embodiment, the host 10 is provided with the accommodating groove 11c, the scanning assembly 20 is accommodated in the accommodating groove 11c in the accommodating state, the host 10 includes a host cavity formed by the host housing 11, the host housing 11 is formed with the accommodating groove 11c, and the rotation angle detecting element 40 is disposed at the bottom of the accommodating groove 11c and is located in the cavity of the host 10, so as to avoid exposing the rotation angle detecting element 40 to the host 10.

As shown in fig. 5, the scanning assembly 20 includes a scanning housing 21, at least a portion of the scanning housing 21 faces the bottom of the accommodating groove 11c and is stacked with the bottom of the accommodating groove 11c when the scanning assembly 20 is in the unfolded state, that is, in the Z-axis direction of the scanning pen 01, at least a portion of the projection of the scanning housing 21 onto the host 10 falls into the accommodating groove 11c, and the magnetic member 50 is disposed on the inner surface of the portion of the scanning housing 21. The groove bottom of the receiving groove 11c may be formed entirely of the groove bottom plate 11a, or may be formed of another structural member that is connected to the groove bottom plate 11a and forms the groove bottom of the receiving groove 11 c.

It will be appreciated that, since the scan housing 21 is opposite to the bottom of the accommodating groove 11c in the accommodating state, the scan housing 21 of the portion where the magnetic member 50 is disposed is still opposite to the bottom of the accommodating groove 11c after the scan housing 21 is rotated to the open state, so that it is ensured that the magnetic field of the magnetic member 50 can be detected by the rotation angle detecting element 40 disposed at the bottom of the accommodating groove 11c regardless of whether the scan assembly 20 is in the accommodating state, the bracket state or the open state, so that the rotation angle detecting element 40 can always detect the rotation angle between the scan assembly 20 and the host 10.

Further, as shown in fig. 11 and 14, along the thickness direction of the scanning assembly 20, i.e., the Z-axis direction, the scanning housing 21 is divided into a third housing 23 and a fourth housing 24, and the third housing 23 and the fourth housing 24 are buckled to form the scanning housing 21, and a scanning element may be disposed in the scanning housing 21. In the accommodated state of the scanning unit 20, the third housing 23 is farther from the bottom of the accommodating groove 11c than the fourth housing 24, i.e., the fourth housing 24 is opposite to the bottom of the accommodating groove 11 c. In the unfolded state of the scanning assembly 20, the third housing 23 is closer to the bottom of the accommodating groove 11c than the fourth housing 24, that is, at least a portion of the third housing 23 and the bottom of the accommodating groove 11c are stacked, which corresponds to the orthographic projection of a portion of the third housing 23 into the accommodating groove 11c falling into the bottom of the accommodating groove 11c, and the magnetic member 50 is disposed on the inner surface of the portion of the third housing 23.

In this way, the magnetic piece 50 is disposed on the portion of the third housing 23 that can be opposite to the storage slot 11c when the scanning assembly 20 is in the unfolded state, so that the distance between the magnetic piece 50 and the rotation angle detecting element 40 is relatively short when the scanning assembly 20 is in the unfolded state, the magnetic flux received by the rotation angle detecting element 40 is relatively large, and the detection of the unfolded state of the scanning assembly 20 by the rotation angle detecting element 40 is relatively timely and accurate, so that the controller can switch the working mode of the scanning pen 01 to the third working mode in time.

Further, as shown in fig. 11, the third housing 23 includes a spindle chamber 231 for accommodating the spindle assembly 100, and the magnetic member 50 is disposed in the spindle chamber 231. The rotating shaft assembly 100 includes a first rotating shaft 110 and a second rotating shaft 120, the host 10 and the scanning assembly 20 are rotatably connected through the first rotating shaft 110 and the second rotating shaft 120, the first rotating shaft 110 and the second rotating shaft 120 are coaxial and are arranged at intervals, and the magnetic member 50 is located between the first rotating shaft 110 and the second rotating shaft 120. In this way, the magnetic member 50 can be prevented from being set up by the rotating shaft assembly 100, the arrangement of the magnetic member 50 does not affect the rotation of the rotating shaft assembly 100, and the space generated by the interval arrangement of the first rotating shaft 110 and the second rotating shaft 120 is reasonably utilized.

In order to improve the accuracy of the output value of the rotation angle detecting element 40 corresponding to the rotation angle, the reliability of the rotation angle detecting element 40 is ensured. The calibration process of the corresponding relation between the output value and the rotation angle is described in detail in the embodiment of the application.

Considering errors of the magnetic member 50 itself, and assembly tolerances of the scanning pen 01 generated during assembly, these factors affect the accuracy of the rotation angle determined according to the output value of the rotation angle detecting element 40. Therefore, a calibration device may be disposed on the production line of the scanning pen 01 to calibrate the rotation angle detecting element 40, so that the correspondence between the output value and the rotation angle stored in the storage device of the scanning pen 01 is more accurate.

The scanning pen 01 is timely informed that the scanning assembly 20 is in the unfolded state, and the scanning pen 01 can be timely switched to the third working mode for realizing the scanning function, so that the scanning pen 01 is awakened. The following description will be given by taking, as an example, a calibration of a rotation angle of the scan assembly 20 near the unfolded state, for example: calibration may be selected at 173 deg. to ensure the margin for the scan assembly 20 to wake up in the deployed state. The calibration procedure is as follows:

The scanning assembly 20 of the scanning pen 01 is rotated to 173 ° and then placed in a calibration device, and the output value of the rotation angle detecting element 40 in the current state is read, for example: the output value of the rotation angle detecting element 40 in the present state is-30 mT. The output value of the calibration device is stored in the memory device described in the above embodiment and written into the rotation angle detection element 40 at the same time.

To ensure the reliability of the calibration process, the following test verification may also be performed on the scanning pen 01 by the calibration device to verify the detection accuracy of the rotation angle detecting element 40. The verification process is as follows: when the scanning assembly 20 of the scanning pen 01 is rotated to 180 degrees, the output value of the current rotation angle detecting element 40 should be theoretically smaller than-30 mT, and meanwhile, the deviation of 2mT can be set, when the output value of the rotation angle detecting element 40 is at-32 mT, the rotation angle detecting element 40 is verified. Similarly, the scanning assembly 20 of the scanning pen 01 can be rotated to 170 degrees, the output value of the current rotation angle detecting element 40 is theoretically larger than-30 mT, and meanwhile, the deviation of 1mT can be set, and when the output value of the rotation angle detecting element 40 is at-29 mT, the rotation angle detecting element 40 passes verification. The calibration and verification process described above is exemplified by 173 °, and a plurality of other angles may be selected as needed to calibrate and verify the rotation angle detecting element 40 in actual operation.

In order to improve the calibration efficiency of the calibration device, it is considered that the output value of the rotation angle detecting element 40 at a partial angle is actually measured, and analog output values are used for other angles, so that a corresponding relationship between the analog output value but with higher accuracy and the rotation angle can be obtained, and the corresponding relationship obtained by the simulation can be stored in the storage device of the finger scanning pen 01, and used as a basis for determining the rotation angle of the scanning assembly 20 by the controller.

Illustratively, some angles between 0 ° and 180 ° may be chosen for calibration. For example: the output values of the rotation angle detecting element 40 may be measured by rotating the scanning assembly 20 to 0 °, 30 °, 60 °, 90 °, 120 °, 150 ° and 180 ° to obtain measured output values of the rotation angle detecting element 40, and then dividing the two continuous measured output values into 30 parts in average for calculating the analog output value.

For example, referring to table 2, when the scan assembly 20 rotates to 0 °, the measured output value of the rotation angle detecting element 40 is a, a= 2.5975mT, when the scan assembly 20 rotates to 30 °, the measured output value of the rotation angle detecting element 40 is B, b= 0.82531mT, and according to the two measured output values, the analog output value of the scan assembly 20 at 10 ° can be simulated to be C, c=a- (a-B)/(30×10= 2.00677. According to the above method, the analog output value of the rotation angle detecting element 40 between 0 ° and 180 ° other than the above 7 angles can be simulated.

By combining the actually measured output values of the angles in table 1 and the analog output values of the angles in table 2, it is known that the analog output values are very close to the actually measured output values, and the corresponding relationship between the obtained output values and the rotation angles is obtained in an analog manner, but the reliability is high, and the corresponding relationship can be stored in the storage device of the scanning pen 01 to be used as the basis for determining the rotation angles of the scanning assembly 20 by the scanning pen 01, so that the efficiency of the calibration process is improved.

TABLE 2

In order to describe in detail how the shaft assembly provides a damping structure of a retaining force for the scanning assembly in the storage state, the support state and the deployed state, and how the scanning assembly automatically springs to the support state after being unlocked by the locking structure, the embodiments of the present application describe the damping structure in the shaft assembly in detail below.

Specifically, the spindle assembly 100 may further include a damping structure 140. The damping structure 140 may be fitted over the first shaft 110, and a retaining force is provided between the host 10 and the scan assembly 20 by the damping structure 140. Specifically, as shown in fig. 6, the damping structure 140 may include an end cam 141, a first restoring member 142, and an end concave wheel 143. The host 10 may drive the end cam 141 to rotate, and the scan assembly 20 may drive the end cam 143 to rotate. The end cam 141 and the end concave wheel 143 may be sleeved on the first rotating shaft 110, and the end cam 141 and the end concave wheel 143 are disposed opposite to each other. The end cam 141 and the end concave wheel 143 can be abutted by the first reset piece 142 to provide the holding force of the damping structure 140.

In some embodiments, as shown in fig. 6 and 14, the spindle assembly 100 may further include a catch plate 111, a second connector 144, and a stopper 145. The baffle plate 111 may be connected to an end position remote from the first rotation shaft 110 to expose a portion of the first rotation shaft 110. Thus, when the first rotation shaft 110 is mounted, the shutter 111 may abut against the inner side of the scan case 21, and a part of the first rotation shaft 110 exposed may extend out of the scan case 21 for connection with the main body case 11 (shown in fig. 5). Of course, the first rotating shaft 110 may also be directly and fixedly connected with the host 10. The connection manner between the first rotating shaft 110 and the host 10 is not particularly limited in the embodiment of the present application.

The cross section of the first rotating shaft 110 (perpendicular to the axial direction of the first rotating shaft 110) may be a non-circular shape such as a kidney shape, a rectangle, a triangle, or other polygons. When the first rotating shaft 110 is connected to the host 10, the host 10 can drive the first rotating shaft 110 to rotate. The end cam 141 may have a hole of the same shape as the cross section of the first rotary shaft 110, and the end cam 141 may be slidably coupled with the first rotary shaft 110 in the axial direction of the first rotary shaft 110. Thus, the end cam 141 may be fixed relative to the first shaft 110 along the circumferential direction of the first shaft 110, so that the host 10 may rotate the end cam 141.

With continued reference to fig. 6 and 14, the second connecting member 144 may be connected to the concave end wheel 143, and the second connecting member 144 may be connected to the scan housing 21 by a connection structure such as a screw or a rivet, so that the scan assembly 20 may rotate the concave end wheel 143. The stopper 145 may be fixedly coupled to one end of the first rotation shaft 110, and the first reset member 142 may be fitted on the first rotation shaft 110 and located between the end cam 141 and the stopper 145. Thus, the end cam 141 can slide on the first rotating shaft 110 under the elastic action of the first restoring member 142. The first restoring member 142 may be a spring, a spring plate, a disc spring, or the like, which is not limited in particular to the specific structure of the first restoring member 142 in the embodiment of the present application.

As shown in fig. 6 and 14, the end surface concave wheel 143 may be provided with a circular hole, so that the first rotating shaft 110 may rotate in the hole of the end surface concave wheel 143, and the end surface concave wheel 143 may be disposed between the end surface cam 141 and the baffle disc 111, so that the end surface cam 141 abuts against the end surface concave wheel 143 through the first reset member 142.

In order to provide a retention force for the scan assembly 20, as shown in fig. 15 and 16, the face cam 141 may include a first boss 1411. The face concave wheel 143 may include a plurality of second protrusions 1431, and grooves 1432 may be formed between adjacent second protrusions 1431. The grooves 1432 may include a first groove 1432a and a second groove 1432b, and the grooves 1432 may have groove walls 1433 and groove bottoms 1434. Wherein the first boss 1411 and the groove wall 1433 have slopes, respectively, to smoothly transition. Thus, under the pushing action of the first restoring member 142 (shown in fig. 6), when the first protruding portion 1411 abuts against the groove wall 1433 and the first protruding portion 1411 is not in contact with the groove bottom 1434, the first protruding portion 1411 has a tendency to move toward the groove bottom 1434, and the tendency of movement can provide the holding force of the scanning assembly 20.

The user may rotate the scan assembly 20 to a preset angle a while using the scan pen 01. At this time, the scanning assembly 20 may be used as a stand so that the host computer 10 may be supported on a desktop by the scanning assembly 20 to facilitate the user's viewing of the target content. Of course, the face cam 141 may be provided with a plurality of first protrusions 1411, and the face concave wheel 143 may be provided with a greater number of grooves 1432 to form adjustable gears in different carrier states. In this way, the user can adjust the bracket states of a plurality of preset angles alpha, so that the display effect of the scanning pen 01 with different angles can be realized. The number of gear steps by which the scanning assembly 20 rotates is not particularly limited in this embodiment.

Specifically, as shown in fig. 17, the end cam 141 may have a first shaft hole 1410, and the first boss 1411 may include a first outer boss 14111 and a second inner boss 14112. The first outer protrusion 14111 and the second inner protrusion 14112 are disposed at both sides of the first shaft hole 1410, respectively, and the first outer protrusion 14111 is far from the first shaft hole 1410, and the second inner protrusion 14112 is near the first shaft hole 1410.

Accordingly, as shown in fig. 18, the end face concave wheel 143 may have a second shaft hole 1430, and the second boss 1431 may include a third outer boss 14311, a fourth outer boss 14312, a third inner boss 14313, and a fourth inner boss 14314. The third and fourth outer protrusions 14311 and 14314 are disposed at both sides of the second shaft hole 1430, respectively, the fourth and inner protrusions 14312 and 14313 are disposed at both sides of the second shaft hole 1430, respectively, the third and fourth outer protrusions 14311 and 14312 are distant from the second shaft hole 1430, and the third and fourth inner protrusions 14313 and 14314 are close to the second shaft hole 1430.

In addition, both ends of the third outer boss 14311 and the third inner boss 14313 have slopes, a first central angle a is provided between a slope bottom of the third outer boss 14311 and a slope bottom of the corresponding third inner boss 14313, a second central angle B is provided between a slope top of the third outer boss 14311 and a slope top of the corresponding third inner boss 14313, and the first central angle a is equal to the second central angle B. Meanwhile, both ends of the fourth outer boss 14312 and the fourth inner boss 14314 have slopes, a third central angle C is provided between the slope bottom of the fourth outer boss 14312 and the slope bottom of the corresponding fourth inner boss 14314, a fourth central angle D is provided between the slope top of the fourth outer boss 14312 and the slope top of the corresponding fourth inner boss 14314, and the third central angle C is equal to the fourth central angle D. Corresponding to the sloping surfaces of the same ends of the third outer protruding portion 14311 and the third inner protruding portion 14313, and the sloping surfaces of the same ends of the fourth outer protruding portion 14312 and the fourth inner protruding portion 14314.

The following embodiments will describe the damping structure 140 of the scanning assembly 20 in detail in each state, as shown in fig. 19-24. As shown in fig. 19, when the scanning assembly 20 is in the storage state, the slope of one end of the first outer boss 14111 may abut against the slope of the fourth outer boss 14312. At the same time, the slope of one end of the second inner protrusion 14112 also abuts the slope of the third inner protrusion 14313. The scanning pen 01 may further include a locking structure (the following embodiments will describe the locking structure in detail) so that the scanning assembly 20 may be locked on the host 10 to maintain the folded state of the scanning assembly 20. The first boss 1411 has a tendency to move toward the groove bottom 1434 of the first recess 1432a to apply a retaining force to the scan assembly 20 that rotates away from the host 10, the scan assembly 20 having a tendency to pop up away from the host 10.

When the locking member is unlocked, as shown in fig. 20, the first outer protrusion 14111 and the second inner protrusion 14112 move and abut against the groove bottom 1434 of the first groove 1432a under the elastic urging force of the first restoring member 142. At this time, a preset angle α (for example, 18 °) is maintained between the scanning assembly 20 and the host 10, so that the scanning assembly 20 hovers at the preset angle α, and thus the scanning assembly 20 may be used as a stand of the host 10, so that a user can watch video.

When the user desires to scan, the scanning assembly 20 may continue to be rotated as shown in FIG. 21. At this time, the first outer boss 14111 abuts against the slope of the third outer boss 14311. The slope at the other end of the first outer lobe 14111 is required to overcome the slope resistance at one end of the third outer lobe 14311 to climb the slope. At this point, the scanning assembly 20 is at an angle of 18-55 degrees with respect to the host 10. As the rotation proceeds, the crest of the first outer boss 14111 reaches the crest position of the third outer boss 14311, and the first outer boss 14111 and the third outer boss 14311 rub against each other. At this point, the scanning assembly 20 is at an angle of 55 ° -150 ° with respect to the host 10.

As the rotation continues, as shown in fig. 22, the first outer protrusion 14111 enters the second groove 1432b, and the scanning assembly 20 is unfolded to be 180 ° from the host 10, so that the scanning assembly 20 cannot be rotated continuously. At this time, however, the slope of the first outer lobe 14111 abuts the slope position of the third outer lobe 14311 and the first outer lobe 14111 is not in contact with the groove bottom 1434 of the second groove 1432b such that the first outer lobe 14111 has a tendency to move toward the groove bottom 1434 of the second groove 1432b, thereby providing a retaining force when the scan assembly 20 hovers in the deployed state. Meanwhile, the slope at the other end of the second inner protruding portion 14112 needs to overcome the slope resistance at one end of the fourth inner protruding portion 14314 to climb the slope. Until the slope of the second inner lobe 14112 reaches the slope of the other end of the fourth inner lobe 14314 and the second inner lobe 14112 is not in contact with the trough bottom 1434 of the second recess 1432b, the second inner lobe 14112 also has a tendency to move toward the trough bottom 1434 of the second recess 1432b, thereby providing a retaining force when the scan assembly 20 hovers in the deployed state.

The first outer lobe 14111 and the second inner lobe 14112 of the present embodiment form a set of inner and outer double-layered cam assemblies, the third outer lobe 14311 and the fourth inner lobe 14314 form a set of inner and outer double-layered cam assemblies, and the fourth outer lobe 14312 and the third inner lobe 14313 form a set of inner and outer double-layered cam assemblies. Through the cam structure form of the inner layer and the outer layer, the protruding part of the inner layer and the protruding part of the outer layer are not symmetrical about the center of the cam. In this way, the design of the different hover angles and the design of the retaining force of the scanning assembly 20 can be achieved, and the protrusions of the inner layer and the protrusions of the outer layer can be flexibly arranged along the circumferential direction of the cam (i.e. the different angle designs of the first central angle a, the second central angle B, the third central angle C and the fourth central angle D in the above embodiment), so that the retaining force of the scanning assembly 20 under the different hover angles can be different.

By way of example, the predetermined angle α of the scan assembly 20 in the cradle state may be designed to be 18 °, i.e., 18 ° between the scan assembly 20 and the host computer 10 when the first outer protrusion 14111 contacts the groove bottom 1434 of the first groove 1432 a. At this time, the first central angle a, the second central angle B, the third central angle C, and the fourth central angle D may be set to 15 °. When the scan assembly 20 is in the deployed state, the scan assembly 20 may have a holding force of 3 ° with respect to the host 10. Of course, the first central angle a, the second central angle B, the third central angle C, and the fourth central angle D may be set to 10 °, 20 °, or other degrees, so that the scanning assembly 20 may have different degrees of retention force with respect to the host computer 10 when the scanning assembly 20 is in the deployed state. The specific retention design between the scan assembly 20 and the host 10 is not particularly limited by the embodiments of the present application.

Further, providing the first boss 1411 and the second boss 1431 as the inner and outer double-layer cams, respectively, can increase the friction area between the face cam 141 and the face concave wheel 143. Because the friction force of the end cam 141 and the end concave wheel 143 rotating under the pushing and resisting action of the first reset piece 142 is fixed, increasing the friction area is beneficial to reducing the abrasion between the end cam 141 and the end concave wheel 143, thereby prolonging the service life of the rotating shaft assembly 100.

In the above embodiment, the first boss 1411 and the second boss 1431 may have different slopes, and the different slopes may adjust the magnitude of torsion force when the face cam 141 and the face concave wheel 143 rotate. The greater the gradient, the greater the torque force required between the face cam 141 and the face concave wheel 143. Conversely, as the gradient is smaller, the torque force required between the face cam 141 and the face concave wheel 143 is also smaller.

In further embodiments, as shown in fig. 17, the first boss 1411 can further include a second outer boss 14113 and a first inner boss 14114. The second outer boss 14113 and the first inner boss 14114 are disposed on opposite sides of the first shaft hole 1410, respectively, and the second outer boss 14113 is remote from the first shaft hole 1410, with the first inner boss 14114 being proximate to the first shaft hole 1410.

Further, the top of the first outer boss 14111 is flush with the top of the first inner boss 14114, and the face cam 141 is in contact with only the top of the first inner boss 14114 during relative rotation of the face cam 141 and the face cam 143. Likewise, the top of the second outer lobe 14113 is flush with the top of the second inner lobe 14112 and the face cam 141 is only in contact with the top of the second outer lobe 14113 during relative rotation of the face cam 141 and the face cam 143.

During the relative rotation of the face cam 141 and the face concave wheel 143, the both ends of the second outer boss 14113 and the first inner boss 14114 are not in contact with the both ends of the second boss 1431. The provision of the second outer boss 14113 and the first inner boss 14114 can increase the friction area between the face cam 141 and the face concave wheel 143, thereby reducing wear between the face cam 141 and the face concave wheel 143. In addition, the second outer lobe 14113 can support the second inner lobe 14112 and the first inner lobe 14114 can support the first outer lobe 14111, thereby improving the service life of the face cam 141.

The above embodiment describes the structure of the spindle assembly 100 having a tendency to rotate away from the host 10 when the scan assembly 20 is in the folded state. In other embodiments, the scan assembly 20 may also have a rotational tendency toward the host 10 when in the collapsed state to prevent the scan assembly 20 from easily disengaging from the host 10 when in the collapsed state. As shown in fig. 23 and 24, the face cam 141 may include a third boss 1412. The end face concave wheel 143 may include a plurality of fourth protrusions 1435, and a third groove 1432c and a fourth groove 1432d may be formed between adjacent fourth protrusions 1431. As shown in fig. 19, the third boss 1412 may also have the first outer boss 14111 in the above-described embodiment, and the fourth boss 1435 may also have the third and fourth outer bosses 14311, 14312 in the above-described embodiment. The remaining structures of the third protrusion 1412 and the fourth protrusion 1435 may be the same as the structure of the rotating shaft assembly 100 in the above embodiment, and will not be described herein.

When the scanning assembly 20 is in the folded state, the slope of the first outer lobe 14111 may not abut the slope of the fourth outer lobe 14312, but rather the slope of the first outer lobe 14111 may abut the slope of the third outer lobe 14311, and the third lobe 1412 does not contact the groove bottom 1434 of the third groove 1432 c. At this time, the scan assembly 20 has a tendency to rotate toward the host 10, i.e., the scan assembly 20 has a holding force with the host 10 to avoid the scan assembly 20 from being easily detached from the host 10 in the folded state.

When a user desires to scan, the scanning assembly 20 may be rotated in a direction away from the host 10. In doing so, the user applies a rotational force to the scanning assembly 20 to cause the third protrusion 1412 to enter the fourth recess 1432d (shown in fig. 24), and as such, the third protrusion 1412 first snaps into the groove wall 1433 of the fourth recess 1432d and the third protrusion 1412 does not contact the groove bottom 1434 of the fourth recess 1432d, such that the scanning assembly 20 still has a tendency to rotate in a direction away from the host computer 10. But at this time, the scanning assembly 20 has been unfolded 180 ° from the host computer 10, so that the third protrusion 1412 cooperates with the groove wall 1433 of the fourth groove 1432d to provide a retaining force for the scanning assembly 20 in the unfolded state, so as to avoid shaking of the host computer 10 during scanning.

Of course, the first boss 1411 or the third boss 1412 may be provided on the face concave wheel 143, and the groove 1432 may be provided on the face cam 141. In addition, depending on the desired hover position of the scanning assembly 20, a plurality of grooves 1432 may be provided on the face concave wheel 143. When the first boss 1411 or the third boss 1412 on the face cam 141 are embedded in the grooves 1432 of different positions, the scan assembly 20 can also hover over different positions of the host computer 10 for ease of use by a user. The specific positions and the specific numbers at which the first boss 1411, the third boss 1412, and the groove 1432 are provided are not particularly limited in the present embodiment.

The above embodiment describes the damping structure of the spindle assembly 100 in detail, and the host 10 and the scanning assembly 20 can not only rotate relative to each other through the spindle assembly 100, but also maintain the host 10 and the scanning assembly 20 in a folded or unfolded fixed position through the spindle assembly 100.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
