The laser module 20 includes a laser skeleton 21 and a laser 22. The laser skeleton 21 is detachably connected to the device main body 10, and the laser 22 is detachably mounted on the laser skeleton 21. When the laser module 20 is assembled on the device main body 10, the laser 22 and the device main body 10 are electrically connected in a detachable manner. That is, the laser module 20 as a whole can be detached from the device main body 10, and the laser 22 can be individually detached from the laser skeleton 21. Here, the laser 22 can be electrically connected to the device main body 10 through a quick-release connector (not shown in the figure), so that the electrical connection between the laser 22 and the device main body 10 can be controlled at the same time as the laser module 20 is assembled or disassembled on the device main body 10. It should be noted that the structure of the device main body 10 described above can adopt a conventional manner in existing three-dimensional scanning devices, which will not be described here.

[0045] As can be seen from the above, since the laser 22 in the three-dimensional scanning device 100 is detachably assembled, the laser 22 in the three-dimensional scanning device 100 can be replaced or upgraded according to the requirements of use to meet the requirements of different application scenarios, so that the three-dimensional scanning device 100 can use different laser beams to expand the scanning surface in different working modes, and achieve the purpose of improving the scanning efficiency. It should be noted that when the laser 22 is damaged, the laser 22 can be replaced alone; when the laser 22 in the three-dimensional scanning device 100 cannot meet the application scenario, the laser 22 can be upgraded alone.

[0046] It should be noted that the number of lasers 22 in the three-dimensional scanning device 100 of the present application is four, including two blue lasers and two infrared lasers, which are distributed in cross, and the blue laser and the infrared laser can work alone; wherein the blue laser is mainly used for completing the regular scanning, and the infrared laser is mainly used for long-distance laser scanning.

In this way, by using the threaded structure between the first fixing member 201 and the device body 10, the user can realize the disassembly and assembly of the laser skeleton 21 on the device body 10 by screwing the first fixing member 201, so as to realize the quick and convenient disassembly and assembly of the laser skeleton 21 on the device body 10.

[0048] As shown in Figure 4 , the laser skeleton 21 is partially protruding and formed with a connecting lug 211, which is correspondingly arranged with the first fixing member 201, and the first fixing member 201 can pass through the corresponding connecting lug 211 and be screwed with the device body 10, so that the first fixing member 201 can realize the assembly connection of the laser skeleton 21 on the device body 10 by pressing the connecting lug 211. Here, the number of connecting lugs 211 is two, and the two connecting lugs 211 are arranged on both sides of the laser skeleton 21.

[0049] In the present application, the laser module 20 further comprises a second fixing member (not shown in the figure), which is arranged corresponding to the laser 22, and is screwed on the laser skeleton 21 and abuts against the corresponding laser 22, for fixing the corresponding laser 22 to the laser skeleton 21. The second fixing member can abut against the laser 22 after passing through the laser skeleton 21, so as to limit the assembly of the laser skeleton 21 to the laser 22, thereby realizing the quick disassembly and assembly of the laser 22 on the laser skeleton 21. Here, the second fixing member is configured as a screw, bolt, screw, etc.

[0050] As preferred, the number of the second fixing member corresponding to each laser 22 is configured as two, which are arranged along the length direction of the laser 22, so that the laser 22 can be fixed to the laser skeleton 21 by the two fixing members, which can improve the stability of the laser 22 when being limited on the laser skeleton 21. Of course, the number of the second fixing member corresponding to each laser 22 can also be one, three or even more, which will not be elaborated here.

[0051] As shown in Figure 3 , Figure 4 , the laser module 20 further comprises a bottom shell 23 and an outer shell 24, which is detachably connected to the bottom shell 23, and a containing cavity (not shown in the figure) is formed between the outer shell 24 and the bottom shell 23, for accommodating the laser skeleton 21 and the laser 22. That is, the laser skeleton 21 and the laser 22 can be wrapped by the bottom shell 23 and the outer shell 24, and the integration of the structure of the laser module 20 is realized, so that the laser module 20 can be packaged and sold, and the transportation of the laser module 20 is facilitated. Here, the outer shell 24 is provided with a first through hole 241 and a second through hole 242, the first through hole 241 is arranged corresponding to the laser 22, and the laser beam generated by the laser 22 during operation can pass through the corresponding first through hole 241 and be emitted outward, that is, the existence of the outer shell 24 will not affect the emission of the laser beam on the laser 22; the second through hole 242 is arranged corresponding to the first fixing member 201, so that the outer shell 24 will not affect the disassembly of the first fixing member 201.

[0052] As shown in Figures 2 to 4As shown, the laser module 20 further comprises a third fixing member 203, which can pass through the shell 24 and be screwed with the laser skeleton 21, for fixing the shell 24 to the laser skeleton 21, so that the dismounting of the shell 24 on the laser skeleton 21 can be realized by screwing the third fixing member 203, thus realizing the quick and convenient dismounting of the shell 24 on the laser skeleton 21. Here, the number of the third fixing member 203 is configured as two, and the two third fixing members 203 are arranged on the two sides of the laser 22, wherein the third fixing member 203 is configured as a bolt or a screw.

[0053] As shown in Figure 4 , one of the laser skeleton 21 and the shell 24 is configured with a socket 212, and the other is configured with a protruding plug rod (not shown in the figure), which can be plugged with the socket 212 and guide the shell 24 to be assembled to the laser skeleton 21. That is, the shell 24 can be positioned by the plug-in cooperation between the plug rod and the socket 212 when being assembled on the laser skeleton 21, and the accuracy of the assembly position between the shell 24 and the laser skeleton 21 is ensured, so that the shell 24 can be conveniently fixed to the laser skeleton 21 by the third fixing member 203. Here, the socket 212 is provided on the laser skeleton 21, and the plug rod is provided on the shell 24. Of course, in other embodiments, the socket can be provided on the shell 24, and the plug rod can be provided on the laser skeleton 21, which will not be expanded here.

[0054] As shown in Figures 2 to 4 , the laser module 20 further comprises a fourth fixing member 204, which can pass through the shell 24 and be screwed with the bottom shell 23, for fixing the bottom shell 23 to the shell 24. So that the dismounting of the bottom shell 23 on the shell 24 can be realized by screwing the fourth fixing member 204, thus realizing the quick and convenient dismounting of the bottom shell 23 on the shell 24. Here, the number of the fourth fixing member 204 is configured as four, and the four fourth fixing members 204 are arranged on the circumferential side of the laser 22, wherein the fourth fixing member 204 can be specifically configured as a bolt, a screw or a screw. Of course, in other embodiments, the fourth fixing member 204 can also be configured as two, three, five or even more, which will not be expanded here.

[0055] As shown in Figure 1 , Figure 3 , and Figure 4As shown, the laser module 20 further comprises a laser panel 25, which is mounted on the shell 24 for shielding the third fixing member 203 and the fourth fixing member 204, and the laser beam generated by the laser 22 can be transmitted through the laser panel 25 to be emitted outward. That is, the laser panel 25 can shield the positions of the third fixing member 203 and the fourth fixing member 204 on the shell 24, and improve the external appearance of the laser module 20, and on the other hand, can also play a waterproof and dustproof role for the assembly of the laser 22 and the laser 22 and the laser skeleton 21. Here, the laser panel 25 can be connected to the shell 24 in a bonding manner, and the material of the laser panel 25 can be configured as glass. Of course, in other embodiments, the laser panel 25 can also be assembled to the shell 24 in a clamping manner.

[0056] As shown in Figures 2 to 4 , the shell 24 is detachably connected with a shielding member 26, and the shielding member 26 is used for shielding the first fixing member 201. Here, the shielding member 26 is detachably assembled to the second through hole 242 of the shell 24, so that the shielding member 26 not only plays a shielding role for the assembly of the first fixing member 201 on the shell 24 and improves the external appearance of the laser module 20, but also plays a waterproof and dustproof role for the assembly of the first fixing member 201 on the shell 24.

[0057] In the present application, the material of the shielding member 26 is configured as an elastic body, and the shielding member 26 can be connected to the shell 24 in a tight-fitting manner, so that the structure characteristics of the elastic deformation of the shielding member 26 facilitate the assembly and connection of the shielding member 26 on the shell 24. Here, the material of the shielding member 26 can be silicone, rubber, etc.

[0058] As preferred, as shown in Figure 1 , Figure 2 , the shielding member 26 partially extends outward relative to the shell 24, which can be manually actuated. That is, the hand can act on the part of the shielding member 26 extending out of the shell 24, so as to further facilitate the disassembly of the shielding member 26 from the shell 24.

[0059] As can be seen from the above, when the laser module 20 needs to be assembled to the device main body 10, the laser 22 can be first placed into the laser skeleton 21 and locked by the second fixing member; then the laser skeleton 21 assembled with the laser 22 is placed into the bottom shell 23, and the laser skeleton 21 is fixed to the device main body 10 by the first fixing member 201; then the outer shell 24 is fixed to the laser skeleton 21 by the third fixing member 203, and the outer shell 24 is connected and fixed with the bottom shell 23 by the fourth fixing member 204; finally, the laser panel 25 and the shielding member 26 are assembled to the outer shell 24. When the laser module 20 needs to be disassembled from the device main body 10, the shielding member 26 can be first disassembled from the outer shell 24, and the first fixing member 201 is exposed, then the assembly limiting of the laser module 20 on the device main body 10 can be released by disassembling the first fixing member 201, and finally the laser 22 can be disassembled from the laser skeleton 21 in combination with the above assembly steps of the laser module 20.
