[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Please refer to Figure 1-Figure 7 .

[0031] Embodiment 1

[0032] like Figure 1-Figure 3As shown, the present embodiment provides a scanner mounting assembly 12, comprising a mounting bracket 1, a scanner mounting plate 2 and an angle adjustment module, wherein the mounting bracket 1 is used to mount the entire scanner mounting assembly 12 on other equipment, such as an AGV vehicle body 13, and the scanner mounting plate 2 is opposite to the mounting bracket 1 and is spaced apart, that is, the scanner mounting plate 2 and the mounting bracket 1 are arranged face to face, and there is a certain interval between the two to provide space for adjusting the angle; the angle adjustment module connects the mounting bracket 1 and the scanner mounting plate 2 and is located therebetween, and the angle adjustment module comprises at least two groups of fastening components 3 spaced apart, and the at least two groups of fastening components 3 are respectively arranged on both sides of the scanner mounting plate 2, and adjust the scanner mounting plate 2 and the mounting bracket 1 to have different intervals; for example, when two groups are arranged When fastening the assembly 3, the interval on one side between the mounting bracket 1 and the scanner mounting plate 2 is adjusted to be different from the interval on the other side. When the opposite side of the mounting bracket 1 and the scanner mounting plate 2 is in a horizontal state, the scanner mounting plate 2 is in an inclined state, thereby causing the scanner 11 installed on the scanner mounting plate 2 to be in an inclined state; of course, the fastening assembly 3 can also be provided in three groups, four groups or multiple groups of other numbers, as long as it is ensured that the scanner mounting plate 2 and the mounting bracket 1 have different intervals on both sides and the scanner mounting plate 2 can have a certain inclination angle; wherein the fastening assembly 3 can be a combination of bolts and springs, or a combination of bolts and elastic gaskets, etc., as long as the interval between the scanner mounting plate 2 and the mounting bracket 1 is adjusted well and the interval can be maintained.

[0033] Specifically, in this embodiment, the fastening assembly 3 includes a fastening bolt 4 and an adjusting spring 5 sleeved on the fastening bolt 4, the fastening bolt 4 passes through the scanner mounting plate 2 and the mounting bracket 1 to connect the scanner mounting plate 2 and the mounting bracket 1, and the adjusting spring 5 is clamped between the scanner mounting plate 2 and the mounting bracket 1 to provide a supporting force for the distance between the scanner mounting plate 2 and the mounting bracket 1. In this embodiment, the different distances between the scanner mounting plate 2 and the mounting bracket 1 are adjusted by adjusting the compression amount of the adjusting spring 5, so that the scanner mounting plate 2 has a tilt angle.

[0034] Furthermore, the mounting bracket 1 and the scanner mounting plate 2 are provided with a through hole and a threaded hole 6, wherein the threaded hole 6 can be provided on the mounting bracket 1 or on the scanner mounting plate 2, and the fastening bolt 4 passes through the through hole and is fastened to the threaded hole 6; the fastening bolt 4 is fixedly connected to one of the mounting bracket 1 or the scanner mounting plate 2 through the threaded hole 6, for example, the threaded hole 6 is provided on the mounting bracket 1, and the fastening bolt 4 is fixedly connected to the mounting bracket 1 through the threaded hole 6, while the connection with the scanner mounting plate 2 is through the through hole, that is, there is no absolute fixed connection relationship between the fastening bolt 4 and the scanner mounting plate 2, and the scanner mounting plate 2 The plate is limited by the bolt head of the fastening bolt 4 on one side and the adjusting spring 5 on the other side to ensure the distance between it and the mounting bracket 1. Since this distance is ensured by the limitation of the bolt head of the fastening bolt 4 and the adjusting spring 5, when the ground is bumpy, the elastic effect of the adjusting spring 5 will buffer the vibration of the scanner mounting plate 2, and then have a buffering effect on the scanner 11, thereby avoiding damage to the scanner 11. In addition, when adjusting the installation angle, it is necessary to keep a certain pre-tightening force on the adjusting spring 5 to avoid the situation where the vibration amplitude of the adjusting spring 5 is too large when there is a slight shake, causing the installation angle to change.

[0035] Furthermore, a group of limiting bolts 7 is provided in the middle between the two groups of fastening components 3. The limiting bolts 7 are fastened to the scanner mounting plate 2 and pass through the scanner mounting plate 2 to abut against the mounting bracket 1. By adding a limiting bolt 7 in the middle, the distance between the scanner mounting plate 2 and the mounting bracket 1 is ensured. While ensuring the spacing between the two, it also avoids affecting the vibration reduction effect of the adjustment springs 5 ​​on both sides.

[0036] In this embodiment, three first parallel lugs 8 extend from the side of the mounting bracket 1, and two L-shaped lugs 10 and a second parallel lug 9 located between the two L-shaped lugs 10 extend from the opposite side of the scanner mounting plate 2. The distance between the L-shaped lug 10 and the first parallel lug 8 is greater than the distance between the first parallel lug 8 and the second parallel lug 9 to ensure that there is sufficient space for angle adjustment. The space between the L-shaped lug 10 and the first parallel lug 8 is used to install the fastening component 3, and the space between the first parallel lug 8 and the second parallel lug 9 is used to install the limit bolt 7.

[0037] Furthermore, the angle adjustment module includes at least three groups of fastening components 3, and the at least three groups of fastening components 3 are distributed on two opposite sides of the scanner mounting plate 2. By setting the fastening components 3 to at least three groups, the stability of the installation of the entire scanner mounting plate 2 is ensured; of course, it can also be set to four groups. When it is set to four groups, it can be symmetrically arranged on both sides, and two groups of fastening components 3 are arranged on each side, and the two groups of fastening components 3 on each side are relatively arranged at both ends of the scanner mounting plate 2, that is, an overall layout is formed in which the fastening components 3 are respectively arranged at the four corners of the scanner mounting plate 2.

[0038] In this embodiment, the cross-section of the mounting bracket 1 can be L-shaped, U-shaped or T-shaped, as long as there is a flat surface for mounting the scanner mounting plate 2 and other surfaces for mounting the overall scanner mounting assembly 12 on other equipment; when the mounting bracket 1 is set to be U-shaped, the scanner mounting plate 2 is installed on the inner side of one arm of the U-shape, so that the scanner 11 is also installed on the inner side of the arm, thereby forming a certain protection for the scanning head part of the scanner 11 through the other arm.
