The identification information obtained by the scanning module 200 can be displayed in the projection area. Changing the projection area is helpful when the placement of the scanner pen is limited, for example, the placement is too low or too high, so that the projection area is lower or higher. When the user needs to lower or raise his head to view the projected image, the projection image is formed in front of the user's line of sight when looking straight ahead. That is, when watching the projection for a long time, the user will not suffer from shoulder and neck pain due to lowering or raising his head for a long time, which helps to enhance the user experience.

[0036] In one embodiment, the projection module 300 includes a projection housing 31 and a projection assembly 32. The projection housing 31 is formed with an accommodation cavity. The projection assembly 32 is disposed in the accommodation cavity and partially exposed from the projection housing 31. The projection assembly 32 is electrically connected to the control main board 400. The projection housing 31 is connected to the scanning pen body 100 through a hinge assembly 33 so that the projection housing 31 rotates around a first axis to change the irradiation direction of the projection of the projection assembly 32. In other embodiments, the projection housing 31 and the scanning pen body 100 may be connected through a universal ball assembly so that the projection housing 31 can rotate in all directions relative to the scanning pen body 100.

The first position and the second position are both on the path of the projection housing 31 moving around the first axis, and the projection housing 31 rotates between the first position and the second position, that is, the projection module 300 has at least two adjustable angles for selection. In other embodiments, the projection module 300 may not have the first abutting surface 311 and the second abutting surface 312, and the scanning pen body 100 may not have the corresponding third abutting surface 14 and the fourth abutting surface 15.

[0038] In one embodiment, the projection module 300 is disposed at one end of the scanning pen body 100 away from the pen tip 11. The projection assembly 32 includes a projector 321, which is exposed at one end of the projection module 300 away from the scanning pen body 100. In the first position, the first abutting surface 311 is disposed on the end surface of the projection housing 31 close to the scanning pen body 100, and the third abutting surface 14 is disposed on the end surface of the scanning pen body 100 away from the pen tip 11. At this time, the center of the projection light of the projector 321 is parallel to the direction of the scanning pen body 100. In the second position, the center of the projection light of the projector 321 intersects with the axial direction of the scanning pen body 100. During the rotation of the projection housing 31, the projection area moves in the up-down direction, thereby changing the height of the projection area, so that when the scanning pen is placed at a lower or higher position, the projection area is adjusted to a height suitable for the user to watch. Furthermore, when the second abutting surface 312 abuts against the fourth abutting surface 15 , the center of the projection light of the projector 321 is perpendicular to the axial direction of the scanning pen body 100 .

When the projection housing 31 is in the first position, the projection housing 31 is folded with the scanning pen body 100, and when the projection housing 31 is in the second position, the projection housing 31 is folded with the scanning pen body 100. The shell 31 and the scanning pen body 100 are fully unfolded. In the first position, the projector 321 is exposed on the side of the projection shell 31 away from the scanning pen body 100, that is, the projection shell 31 and the scanning pen body 100 can be unfolded to a certain angle so as to form a triangular bracket between the placement surface, and the height and projection angle of the projector 321 can be adjusted by adjusting the unfolding degree of the projection shell 31 and the scanning pen body 100, thereby adjusting the height of the projection area, so that when the scanning pen is placed lower or higher, the projection area can be adjusted to a height suitable for the user to watch.

[0040] In one embodiment, the hinge assembly 33 includes a hinge column 331 and a suspension assembly 335 disposed on the periphery of the hinge column 331. The axis of the hinge column 331 is configured as a whole with the first axis. The suspension assembly 335 is used to relatively fix the projection housing 31 and the scanning pen body 100 at a preset angle, that is, the projection housing 31 can be relatively fixed with the scanning pen body 100 between the first position and the second position, so that the projection module 300 has more than two adjustable angles to choose from. That is, when the user applies a certain force to the projection housing 31, rotates the projection housing 31 to the expected angle, and then releases the projection housing 31, the projection housing 31 can be stopped at the expected angle under the action of the suspension assembly 335, so as to be relatively fixed with the scanning pen body 100.

The user applies a certain force to the projection housing 31, so that the rack 332 slips out of the currently meshed toothed structure 337, and the rack 332 can slide relative to the toothed structure 337. When the force applied to the projection housing 31 is removed, the rack 332 re-meshes with the toothed structure 337, so that the projection housing 31 and the scanning pen body 100 are relatively fixed. The physically formed toothed structure 337 is durable, and the protruding rack 332 will not be easily worn, which helps to reduce the frequency of maintenance. In addition, the forming process of the toothed structure 337 is mature, which helps to reduce the difficulty and time of production. In other embodiments, a damping structure may be provided on the suspension component 335 to increase the friction force so that the projection housing 31 and the scanning pen body 100 are relatively fixed at a preset angle.

The suspension assembly 335 includes a supporting plate 336 provided at both ends of the hinge column 331. The toothed structure 337 includes a rack groove 338. The rack groove 338 is provided on the side of the supporting plate 336 facing the projection housing 31 and can be meshed with the rack 332. When a user applies a certain force to the projection housing 31, the rack 332 disengages from the currently engaged rack groove 338 and rolls on the supporting plate 336. When the force applied to the projection housing 31 is removed, the rack 332 re-engages with the rack groove 338 to relatively fix the projection housing 31 and the scanning pen body 100. In other embodiments, a toothed structure 337 may be provided at the connection between the supporting ear 13 and the connecting column 333, and the rack 332 may be provided on the peripheral side of the connecting column 333 to engage with the toothed structure 337.

[0043] In one embodiment, the hinge column 331 is provided with a wire hole 334, and both ends of the wire hole 334 are exposed on both sides of the hinge column 331, one end is connected to the connection hole 12, and the other end is connected to the accommodating cavity. The wires used for electrical connection between the control main board 400 and the projection assembly 32 pass through the connection hole 12, the wire hole 334, the accommodating cavity, and are connected to the projection assembly 32 from the scanning pen body 100. Furthermore, when the projection housing 31 is in the first position or the second position, the wire hole 334 is not exposed to the outside, so as to prevent water vapor and dust from entering the scanning pen body 100 and the accommodating cavity. In other embodiments, the hinge column 331 may not be provided with a wire hole 334, and a conductive terminal may be provided on the hinge column 331, and a conductive sheet extending circumferentially along the hinge column 331 may be provided on the supporting plate 336. When the hinge column 331 rotates in the connecting hole 12, the conductive terminal maintains contact with the conductive sheet, so that the projection assembly 32 and the control main board 400 in the scanning pen body 100 maintain electrical connection.

[0044] In one embodiment, the hinge column 331 and the projection housing 31 are integrally formed. This helps save the molding material of the hinge column 331. Furthermore, the projection housing 31 is provided with an avoidance groove 313 corresponding to the support ear 13, the support ear 13 extends into the avoidance groove 313, and the avoidance groove 313 extends along the extension direction of the support ear 13 to avoid the support ear 13 limiting the rotation range of the projection housing 31 during the rotation of the projection housing 31.
