[0038] The utility model provides a scanning pen.
[0039] See also Figures 1 to 7In one embodiment of the utility model, the scanning pen includes a scanning pen body 100, a scanning module 200, a projection module 300, a control mainboard 400 and a support module 500. One end of the scanning pen body 100 is provided with a pen head 11. The scanning module 200 is arranged at one end of the scanning pen body 100 close to the pen head 11. The scanning module 200 is used to obtain identification information. The projection module 300 is arranged in the scanning pen body 100. The projection module 300 is used to project and display the obtained identification information. The control mainboard 400 is arranged in the scanning pen body 100. The control mainboard 400 is electrically connected to the scanning module 200 and the projection module 300 respectively. The support module 500 includes a sleeve 51 and a support foot 52. The sleeve 51 is sleeved on the scanning pen body 100 and can extend relative to the axis of the scanning pen body 100. The support foot 52 is movably connected to the sleeve 51 and has an extended state and a folded state. When projection is needed, the support foot 52 is changed to the extended state. In the extended state, the support foot 52 is away from the scanning pen body 100 to stably support the scanning pen body 100. The projection light emitted by the projection module 300 will not shake easily, which helps to improve the stability of the projection. At this time, the scanning pen body 100 can move relative to the sleeve 51 to adjust the irradiation height of the projection light emitted by the projection module 300, so that the user can watch the projection. After the projection is completed, the support angle can be changed to the folded state. In the folded state, the support foot 52 is close to the scanning pen body 100, so that the user holds the scanning pen to scan the area to be scanned, and the support foot 52 will not hinder the movement of the scanning pen.
[0040] In one embodiment, at least three supporting legs 52 are provided and distributed along the circumference of the sleeve 51, that is, in the unfolded state, the supporting legs 52 are combined into a tripod, so that the scanning pen body 100 can be stably and vertically stood on the placement surface of the scanning pen, so as to accurately adjust the movement of the projection module 300 in the height direction. In the folded state, the plurality of supporting legs 52 enclose a receiving space 521, the scanning pen body 100 passes through the receiving space 521, and the pen head 11 extends out of the receiving space 521, that is, the supporting legs 52 in the folded state will not affect the operation of the scanning module 200. In the process of the supporting legs 52 changing from the folded state to the unfolded state, after the supporting legs 52 rotate to be away from the scanning pen body 100, the sleeve 51 moves along the extension direction of the axis of the scanning pen body 100 to approach the pen head 11, so that in the unfolded state, the pen head 11 abuts against the placement surface of the scanning pen, or there is a gap between the pen head 11 and the placement surface of the scanning pen, so as not to affect the support of the supporting legs 52. In other embodiments, the support foot 52 may be provided with one, and a triangular support structure is enclosed between the support foot 52, the scanning pen body 100 and the placement surface to stably support the scanning pen body 100.
[0041] In one embodiment, the cross-sectional shape of the scanning pen body 100 is configured as a circle, and the side of the support foot 52 facing the scanning pen body 100 is provided with an inner concave arc surface 522, and the inner concave arc surface 522 extends along the length direction of the scanning pen body 100. At this time, the scanning pen body 100 and the groove can fit tightly, which helps to reduce the volume of the receiving space 521 on the scanning pen, and further reduce the volume of the scanning pen. At the same time, the support foot 52 in the folded state can play a better protective role for the scanning pen body 100. In other embodiments, the cross-sectional shape of the scanning pen body 100 can also be configured as a square, and the side of the support foot 52 facing the scanning pen body 100 is provided with a groove that matches the square.
[0042] In one embodiment, the side of the support foot 52 away from the scanning pen body 100 includes a convex arc surface 523, and the arc center of the convex arc surface 523 is set at the axis of the scanning pen body 100, that is, on the cross section of the scanning pen, the circle enclosed by multiple convex arc surfaces 523 and the circle of the scanning pen body 100 are concentric circles, and the convex arc surface 523 extends along the length direction of the scanning pen body 100, so that the user can hold the support foot 52 in the folded state during scanning, and have a better hand feel. When the side of the support foot 52 close to the scanning pen body 100 is provided with an inner concave arc surface 522, the side of the support foot 52 away from the scanning pen body 100 is provided with an outer convex arc surface 523, which helps to reduce the production materials of the support foot 52 and reduce the production cost. In other embodiments, the side of the support foot 52 away from the scanning pen body 100 may not be provided with an outer convex arc surface 523.
[0043] In one embodiment, the lower end of the sleeve 51 is hinged to the upper end of the support leg 52, and the upper end surface of the support leg 52 is provided with an abutting inclined surface 524. In the unfolded state, the abutting inclined surface 524 abuts against the lower end surface of the sleeve 51, so that the support leg 52 rotates to a preset angle to support the sleeve 51. That is, when the support leg 52 rotates to a preset angle, the abutting inclined surface 524 abuts against the lower end surface of the sleeve 51. When the scanning pen is placed on the placement surface, under the influence of the weight of the scanning pen itself, the abutting inclined surface 524 maintains abutment with the lower end surface of the sleeve 51, and the support leg 52 and the sleeve 51 can be relatively fixed and support the scanning pen body 100. In other embodiments, there can also be a locking member between the sleeve 51 and the support leg 52, so that the sleeve 51 and the support leg 52 can be fixed at a preset angle.
[0044] In one embodiment, the sleeve 51 and the scanning pen body 100 are connected by threads. That is, an external thread is formed on the outer surface of the scanning pen body 100, and an internal thread is formed on the inner surface of the sleeve 51. The external thread and the internal thread can be adapted to each other. When the scanning pen body 100 is screwed on the sleeve 51, the scanning pen body 100 and the sleeve 51 move relative to each other. In other embodiments, the sleeve 51 and the scanning pen body 100 can also be locked and connected by a locking member, for example, the locking member includes a semicircular clamp and a locking bolt, and the locking bolt tightens the semicircular clamp so that the semicircular clamp presses the sleeve 51 and the scanning pen body 100 to fix the sleeve 51 and the scanning pen body 100.
[0045] In one embodiment, the projection module 300 is disposed at one end of the scanning pen body 100 away from the pen tip 11, and is movably connected to the scanning pen body 100, so that the projection module 300 can be rotated on the scanning pen body 100, so that the orientation of the projection module 300 on the scanning pen body 100 can be changed without rotating the support module 500, so as to align the projection light emitted by the projection module 300 with the area to be projected. In other embodiments, the projection module 300 can also be fixedly connected to the scanning pen body 100.
[0046] In one embodiment, the projection module 300 includes a projection housing 31 and a projection assembly 32. The projection assembly 32 is disposed in the projection housing 31 and is electrically connected to the control mainboard 400. The projection assembly 32 includes a projection lamp 321. The projection lamp 321 is exposed on the side of the projection housing 31 and emits projection light. The projection housing 31 can rotate around the axis of the scanning pen body 100 to adjust the irradiation direction of the projection light in the horizontal direction. In other embodiments, the projection housing 31 can also rotate around a second axis, and the extension direction of the second axis is arranged to intersect with the extension direction of the axis of the scanning pen body 100.
[0047] See also Figure 7In one embodiment, the projection module 300 includes a shaft assembly 33, which is disposed in the scanning pen body 100 and includes a plurality of mutually insulated conductive rings 331 and a plurality of mutually insulated conductive pins 332. The plurality of conductive rings 331 correspond to and are connected to a plurality of wires in the projection assembly, respectively. The conductive pins 332 are respectively connected to a plurality of wires of the control motherboard 400 to form a plurality of conductive paths. The conductive pins 332 abut against the outer peripheral surface of the conductive rings 331. The plurality of conductive rings 331 are arranged at intervals along the extension direction of the axis of the scanning pen body 100. The conductive ring 331 can rotate around the axis of the scanning pen body 100, and during the rotation process, the conductive ring 331 and the conductive pin 332 can maintain contact, so that when the projection assembly 32 rotates around the axis of the scanning pen body 100 at any angle on the scanning pen body 100, it can achieve signal transmission with the control main board 400, so as to avoid the situation that the wires are loosened or broken after the projection assembly 32 rotates excessively on the scanning pen body 100, which helps to improve the stability of the electrical connection between the projection assembly 32 and the control main board 400. In other embodiments, the conductive pin 332 can be electrically connected to the projection assembly 32, and the conductive ring 331 can be electrically connected to the control main board 400.
