Detailed Description
Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 shows the utility model provides a main structure of looking down of orientable laser pen, fig. 2 shows the utility model provides a structure of looking down of orientable laser pen, fig. 3 shows the utility model provides a section structure of looking down of orientable laser pen, fig. 4 shows the utility model provides a taper sleeve looks sideways at local enlarged structure.
Referring to fig. 1 to 4, the present invention provides a directional laser pen, which includes a protective casing 11 for supporting and protecting, and a controller module 116 disposed inside the protective casing 11, wherein a signal conversion module 115 is further disposed inside the protective casing 11, a first infrared emitting device 12, a second infrared receiving device 13, and a laser emitting device 14 are disposed at one end (output end) of the protective casing 11, wherein the first infrared emitting device 12 and the second infrared receiving device 13 are all connected to the controller module 116 through the signal conversion module 115, and the laser emitting device 14 is directly connected to the controller module 116; furthermore, a first infrared receiving device 161 and a second infrared emitting device 162 are disposed on an external object 16 to be directed (such as a teaching blackboard, a multimedia whiteboard, etc.), and the first infrared receiving device 161 is electrically connected to the second infrared emitting device 162 through a controller.
It should be noted that the signal conversion module 115 is an existing modulation and demodulation device, and is mainly used for modulating an infrared signal that needs to be sent by the first infrared transmitting device 12 and demodulating an infrared signal that is received by the second infrared receiving device 13, and sending the demodulated digital or analog signal to the controller module 116, and in addition, as for the controller module 116, a single chip microcomputer of an existing type, such as a 51-series single chip microcomputer and a 32-series single chip microcomputer, is generally selected.
In actual use, when the laser pen is required to emit laser light, the orientable laser pen firstly emits a set of first infrared signals 121 associated with emitting laser light from the first infrared emitting device 12 through the controller module 116 in cooperation with the signal conversion module 115; at this time, when the orientable laser pointer points at the object 16 to be pointed, the first infrared receiving device 161 on the object 16 to be pointed receives the first infrared signal 121, and the second infrared receiving device 13 on the orientable laser pointer emits a second infrared signal 163 different from the first infrared signal 121 through the second infrared emitting device 162, because the infrared ray is in straight-line propagation, the second infrared receiving device 13 receives the second infrared signal 163, the second infrared receiving device 13 transmits information carried by the second infrared signal 163 to the controller module 116 through the signal conversion module 115, and the controller module 116 controls the laser emitting module to emit the corresponding colored laser 141.
It should be noted here that, firstly, because the propagation speed of the infrared ray is extremely fast, the phenomenon that the signal is extended due to the transmission of the infrared signal before the colored laser light 141 is emitted is not caused in practical use; secondly, since the invention of the present invention is to utilize the infrared principle, the modulation and demodulation principle of the signal conversion module 115 and the control principle of the controller module 116 to realize the orientable function of the laser pen, the infrared principle, the modulation and demodulation principle of the signal conversion module 115 and the control principle of the controller module 116 are all the prior art, and therefore the detailed description of the principle is omitted; third, the infrared receiving device (especially the first infrared receiving device 161) has a receiving range capable of receiving the first out-of-hole signal from the desired direction.
In addition, it should be noted that the infrared emission tube on the infrared emission device can be set to different emission angles, that is, emission half angles, and if the emission angle is 45 °, the radiation range of infrared emission is a 90 ° view angle range with the laser pen as the vertex; if the emission angle is 60 deg., the radiation range of infrared emission is 1200 deg. viewing angle range with the laser pointer as the vertex. However, since the present invention is directed to controlling the emission angle of laser light by the emission of infrared light to realize the directional function of laser light, the emission angle of the infrared emission tube of the infrared emission device needs to be set relatively small (e.g., 10 ° to 45 °) to prevent colored laser light from being emitted when the laser pen is directed to the audience. Of course, although the smaller the emission angle of the infrared emission tube on the infrared emission device, the more accurate the laser orientation function thereof, for example, the emission angle of the infrared emission tube on the infrared emission device is limited to 30 °.
However, considering the limitation of the receiving range of the infrared receiving device, a plurality of first infrared receiving devices 161 may be disposed on the object 16 to be pointed, and in the actual setting process, the number of the first infrared receiving devices 161 may be determined according to the emission angle of the infrared emission tube, and the smaller the emission angle setting of the infrared emission tube is, the more the number of the first infrared receiving devices 161 needs to be disposed, specifically, as long as the laser orientation can be achieved. In addition, the receiving principle of the infrared receiving device is also the prior art, and is not described herein again.

In the actual use process, when some information needs to be transmitted, the output part 176 of the usb disk 17 can be slid to the outside of the protective shell 11 from the through hole 18 and connected to corresponding equipment, and after the use is finished, the output part 176 of the usb disk 17 is slid into the protective shell 11, so that the usb disk 17 is protected, and the service life of the usb disk is prolonged.
Specifically, a support rod 172 is fixed on the side wall of the usb flash disk 17, a rectangular hole 173 corresponding to the support rod 172 is formed in the side wall of the protective casing 11, and the support rod 172 extends to the outside of the protective casing 11 through the rectangular hole 173; a slider 174 is fixed to a portion of the support rod 172 extending to the outside of the protective case 11. Through the supporting rod 172 and the sliding block 174 which are connected with the USB flash disk 17, the sliding of the USB flash disk 17 on the sliding groove 171 can be controlled outside the protective shell 11, and the practicability of the device is improved.
More specifically, an elastic receiving groove 175 adapted to the usb disk 17 is disposed at an end of the sliding groove 171 away from the output portion 176, and in an actual use process, when the output portion 176 of the usb disk 17 needs to be received in the protective housing 11, the sliding block 174 can be controlled to contract the usb disk 17 toward the protective housing 11, and as the usb disk 17 moves, an end of the usb disk 17 away from the output portion 176 is closer to the elastic receiving groove 175, and when the end of the usb disk 17 away from the output portion 176 is limited in the elastic receiving groove 175, the sliding block 174 can be stopped.
It should be noted that, the inside of the elastic receiving groove 175 is made of a soft material (such as rubber, sponge, etc.), and when one end of the usb disk 17 away from the output portion 176 is received in the elastic receiving groove 175, the inside of the elastic receiving groove 175 provides a small pressing force to the outer wall of the usb disk 17, and the pressing force can fix the position of the usb disk 17 to a certain extent, but does not fix the usb disk 17 too fast, and the usb disk 17 can be removed from the elastic receiving groove 175 through the slider 174.
In a specific embodiment of the present invention, a power supply module 117 is further disposed inside the protective casing 11, and the controller module 116 and the signal conversion module 115 are both connected to the power supply module 117, so as to supply power to the controller module 116 and the signal conversion module 115.
