[0043] like Figures 1-5 As shown, a protective device 100 for a three-dimensional laser scanner according to an embodiment of the present invention includes a supporting structure 1, a protective mechanism 2 and a driving mechanism 3.

[0044] The supporting structure 1 includes a supporting plate 11, a base 12, and a placement groove 13; the base 12 is vertically arranged, the supporting plate 11 is horizontally arranged above the base 12 and connected to the base 12, and the placement groove 13 is arranged on the upper surface of the supporting plate 11, and the placement groove 13 is used to place a three-dimensional laser scanner.

[0045] The protective mechanism 2 includes a first protective cover 21 and a second protective cover 22, which are respectively disposed on both sides of the placement groove 13 in the first direction X; a first opening is provided on the surface of the first protective cover 21 opposite to the second protective cover 22, and a second opening is provided on the surface of the second protective cover 22 opposite to the first protective cover 21.

[0046] The first protective cover 21 and the second protective cover 22 are slidably connected to the support plate 11, so that the first protective cover 21 and the second protective cover 22 can move closer to or further away from each other;

[0047] The drive mechanism 3 is located on one side of the support plate 11 in the second direction Y. The drive mechanism 3 is connected to the first protective cover 21 and the second protective cover 22 respectively, and is used to drive the first protective cover 21 and the second protective cover 22 to move closer or further away from each other.

[0048] Among them, the first direction X and the second direction Y are perpendicular to each other in the horizontal direction;

[0049] When the first protective cover 21 and the second protective cover 22 are close to each other and the first opening and the second opening are in contact, the first protective cover 21 and the second protective cover 22 form a protective cavity, and the placement groove 13 is located in the protective cavity.

[0050] Based on the above technical solution, the protective device 100 for the 3D laser scanner is set up in an outdoor scene via the base 12; the first protective cover 21 and the second protective cover 22 are driven to move closer to each other via the driving mechanism 3 so that the first opening and the second opening fit together, thereby forming a protective cavity by the first protective cover 21 and the second protective cover 22. The 3D laser scanner is placed in the placement slot 13 located in the protective cavity; this is to store the 3D laser scanner and prevent it from being directly exposed to the external environment, thereby reducing the damage to the 3D laser scanner caused by rain or a large amount of dust; and the first protective cover 21 and the second protective cover 22 can be driven away from each other via the driving mechanism 3 to open the protective cavity, thereby allowing the 3D laser scanner to be taken out for use.

[0051] Furthermore, such as Figure 1 and Figure 2 As shown, in order to specifically realize the driving mechanism 3 driving the first protective cover 21 and the second protective cover 22 to move closer or further apart from each other; the driving mechanism 3 includes a drive motor 31, a driving gear 32, a driven gear 33, a rotating rod 34, a first connecting member 35, and a second connecting member 36;

Since the first protective cover 21 and the second protective cover 22 are slidably connected to the support plate 11 respectively, and one end of the first connecting member 35 is fixedly connected to the first protective cover 21 and the other end is screwed to the rotating rod 34; one end of the second connecting member 36 is fixedly connected to the second protective cover 22 and the other end is screwed to the rotating rod 34, when the rotating rod 34 rotates, the first connecting member 35 and the second connecting member 36 screwed to the rotating rod 34 will move closer to each other or further away from each other, so as to drive the first protective cover 21 and the second protective cover 22 to move closer to each other or further away from each other.

[0056] Furthermore, such as Figure 1 and Figure 2 As shown, to specifically realize the screw connection between the first connecting member 35 and the second connecting member 36 and the rotating rod 34, the rotating rod 34 has a rotating groove at both ends, and the peripheral wall of the rotating groove is provided with an internal thread; the first connecting member 35 and the second connecting member 36 are screwed to the rotating rod 34 through the rotating grooves at both ends of the rotating rod 34.

One end of the U-shaped ends of the first connector 35 is fixedly connected to one side surface of the first protective cover 21, and the other end is inserted into the rotating groove and screwed to the rotating groove. One end of the U-shaped ends of the second connector 36 is fixedly connected to one side surface of the second protective cover 22, and the other end is inserted into the rotating groove and screwed to the rotating groove. This enhances the reliability of the connection between the first connector 35 and the second connector 36 and the first protective cover 21, the second protective cover 22 and the rotating rod 34.

[0058] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, to facilitate the installation of the drive mechanism 3, the supporting structure 1 also includes a mounting plate 14;

[0059] The mounting plate 14 is horizontally positioned and fixedly connected to one side of the support plate 11 in the second direction Y; the drive motor 31 is fixedly mounted on the upper surface of the mounting plate 14.

[0062] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, in order to facilitate the drainage of rainwater accumulated in the sliding groove 111, a plurality of guide holes 112 are provided at the bottom of the sliding groove 111; one end of the guide hole 112 penetrates the sliding groove 111, and the other end penetrates the lower surface of the support plate 11.

[0063] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, in order to reduce the friction between the first protective cover 21 and the second protective cover 22 during movement and make the movement smoother, two guide grooves 113 are provided in parallel at intervals in the middle of the support plate 11.

[0064] The guide groove 113 extends along the first direction X and penetrates the upper and lower surfaces of the support plate 11;

[0065] The first protective cover 21 and the second protective cover 22 are both fixedly provided with pulleys 24 at their bottom ends in the second direction Y. The sliding direction of the pulleys 24 is parallel to the guide groove 113. The first protective cover 21 and the second protective cover 22 are slidably connected to the guide groove 113 through the pulleys 24.

[0066] Furthermore, such as Figure 3 and Figure 4 As shown, to enhance the isolation effect of the protective device 100 for the 3D laser scanner against rain and dust, the protective device 100 for the 3D laser scanner further includes a sealing mechanism 4, which includes a first sealing strip 41 and a second sealing strip 42.

[0069] When the first protective cover 21 and the second protective cover 22 are close to each other and the first opening and the second opening are in contact, the sealing block 421 is inserted into the sealing groove 410, so that the first sealing strip 41 and the second sealing strip 42 are sealed together.

[0070] The working process of this utility model is as follows: the drive motor 31 starts and drives the main shaft to rotate, thereby driving the drive gear 32 to rotate, which in turn drives the driven gear 33 meshing with the drive gear 32 to rotate, and then drives the rotating rod 34 to rotate; so that the first connecting piece 35 and the second connecting piece 36 screwed to the rotating rod 34 move closer or further away from each other, thereby driving the first protective cover 21 and the second protective cover 22 to move closer or further away from each other, thereby forming the protective cavity as needed or opening the protective cavity to realize the storage or retrieval of the three-dimensional laser scanner.

[0071] In summary, this utility model embodiment provides a protective device 100 for a 3D laser scanner, which includes a supporting structure 1, a protective mechanism 2, and a driving mechanism 3.

This storage method prevents the 3D laser scanner from being directly exposed to the external environment, reducing damage from rain or dust. Furthermore, the driving mechanism 3 can be used to move the first protective cover 21 and the second protective cover 22 away from each other to open the protective cavity, allowing the 3D laser scanner to be retrieved for use.
