Description

Technical Field

[0001] The utility model relates to the field of magnetic bases, and in particular to a magnetic base for a laser radar. Background Art

[0002] Existing laser radars are fixed with structures such as bolts, but this method is more complicated in the installation and disassembly process. In response to this, a magnetic base has emerged to fix the laser radar. For example, the Chinese utility model patent with the announcement number CN212905467U discloses a square shell, the lower end of which is bonded with a soft rubber pad that can fit the surface of the vehicle body and increase friction, and a magnet plate that can attract the lower side of the vehicle body is installed in the shell, and a vertical mounting plate for radar installation is fixed to one side of the upper end of the shell; preferably, it also includes a threaded mechanism connected between the magnet plate and the upper end of the shell, and when the threaded mechanism rotates, it can drive the magnet plate to move up and down along the shell to change the attraction force on the vehicle body. The magnetic base mainly uses a spiral structure set on the upper end of the magnet plate to move the magnet plate up and down, change the distance between the magnet and the vehicle body, and thus achieve change in the attraction force. However, this type of base has the following problems: 1. The space between the spiral rod and the laser radar is small, which makes it inconvenient to operate the spiral rod; 2. The spiral rod is set at the upper end, and it is more laborious to pull it apart at the upper end to overcome the attraction force of the magnet. Utility Model Content

[0003] The purpose of the utility model is to provide a magnetic base for laser radar. The utility model changes the attraction between the magnet and the vehicle body by lifting and adjusting, which is easy to operate, saves time and effort, and improves the convenience of disassembly.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0021] Embodiment: A magnetic base for laser radar, comprising a base body 1 and a base cover 2, as shown in the attached Figure 1 As shown, a soft rubber pad for increasing friction that can fit the surface of the vehicle body is bonded to the lower end of the base body, and the base cover 2 is installed with a fixing bracket 3 for fixing the laser radar. A plurality of fixing side branches 14 are fixed to the upper end of the fixing bracket 3, and the fixing side branches 14 are connected to the laser radar through bolts. The bolt connection facilitates installation and disassembly when problems occur with the laser radar; a vertical shaft 4 is installed in the middle of the base body 1 and the base cover 2, and a slidable magnet 5 is installed on the vertical shaft 4, and the magnet 5 includes a magnetic frame 20 slidably connected to the vertical shaft 4, as shown in the attached Figure 4 As shown, a plurality of magnetic blocks 21 are placed in the magnetic frame 20. The magnetic blocks will be demagnetized under the influence of various external factors. If the magnetism of individual magnetic blocks disappears, some of the magnetic blocks can be replaced. The base body 1 has a cavity 6 on one side, as shown in the attached Figure 2 As shown, a bracket 7 is installed in the cavity 6, and a linkage member 8 connected by a torsion spring is provided on the bracket 7. A sleeve member 9 is installed on the inner wall of the cavity 6. Figure 3 As shown, a fixing nut 10 is installed on one side of the sleeve 9, and a matching adjusting rod 11 is installed in the fixing nut 10. The inner end of the adjusting rod 11 is connected to one end of the linkage 8. A fixing ring 16 is installed on the inner end of the adjusting rod 11. The fixing ring 16 contacts one end of the linkage 8. Under the action of the torsion spring, one end of the linkage will cling to the fixing ring. A positioning seat 12 is installed at the bottom of the base body 1. A slidable top column 13 is installed in the positioning seat 12. The upper end of the top column 13 contacts the bottom of the magnet 5. The other end of the linkage 8 is matched and connected with the circumference of the top column 13. Figure 3 In the process, the top column is in a lifted state, and the adjusting rod is rotated to move the adjusting rod outward. The adjusting rod causes the linkage member to rotate through the fixing ring, and the linkage member drives the top column to rise.

[0022] An insulating plate 15 is provided on the upper part of the base body 1, and there are also metal parts on the upper cover of the base. In order to reduce the attraction between the metal parts and the magnet and the influence of the parts, an insulating plate is provided on the upper end of the base body. The top column 13 has an annular portion 17 on the circumferential surface, and the other end of the linkage 8 has an arc portion 18 that conflicts with the annular portion 17. After the linkage is deflected, the arc portion will conflict with the annular portion of the top column to achieve the rise of the top column. The upper end of the top column 13 has a top portion 19 that conflicts with the bottom of the magnet 5. The upper end of the top column is a top portion structure. The lifting force is increased by reducing the contact area between the top column and the magnet, making it easier to lift the magnet.

[0023] The working principle of the utility model: in the initial state, an attractive force will be generated between the magnet and the vehicle body, the base body will adsorb the vehicle body, the bottom of the top column will fit with the bottom of the positioning seat, and the outer end of the adjusting rod will be close to the fixing nut. At this time, when disassembling the base body, the adjusting rod is rotated outward, and the adjusting rod drives the linkage part to rotate through the fixing ring. The arc portion at one end of the linkage part conflicts with the annular portion of the top column, driving the top column to push out upward, realizing the upward movement of the magnet, and the distance between the magnet and the vehicle body becomes longer, thereby changing the attractive force and facilitating the disassembly of the base body; an adjustment mechanism is set on the side of the base body, which can avoid interference with the laser radar compared to setting the upper end of the base body, and is convenient for adjustment. Secondly, the magnet is moved in a jacking manner, which is more labor-saving and more convenient for disassembly and assembly.
