Description

Technical Field

[0001] This utility model belongs to the field of radar correction, specifically, it relates to a radar correction structure suitable for unmanned driving. Background Technology

[0002] Autonomous vehicles require LiDAR for autonomous driving, which is an important tool for obstacle segmentation and detection and laser SLAM-assisted localization in autonomous driving systems. Autonomous vehicles drive in complex environments. When driving on uneven roads, sand particles can easily impact the radar surface, causing damage to the radar. The impact of sand and gravel can also cause the radar to deviate.

[0003] To address these shortcomings, a radar correction structure suitable for autonomous driving is proposed. Utility Model Content

[0004] The technical problem to be solved by this invention is to overcome the shortcomings of the existing technology and provide a radar correction structure suitable for unmanned driving.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A radar correction structure suitable for unmanned driving includes a housing, on which a radar body is mounted, and a cross-shaped locking post is mounted on one side of the radar body.

[0007] A threaded annular plate is fitted inside the housing. One end of the annular plate is attached to one side of the radar body, which facilitates positioning the radar body inside the housing via the annular plate. The radar body is also placed inside the housing via the slot. A positioning disc is elastically and slidably fitted on the other side of the annular plate, which is mounted on one side of the annular plate via a spring. A positioning rod is threaded onto one end of the positioning disc, and one end of the positioning rod is engaged with one end of the cross-shaped locking post.

[0008] Optionally, the housing has a slot and a threaded groove communicating with the radar body. The radar body is located inside the slot. The outer wall of the annular plate has an external thread, which engages with the threaded groove. This facilitates the annular plate's engagement with the housing via the external thread and the threaded groove. The inner wall of the annular plate has multiple first recesses evenly distributed, and the outer wall of the positioning disk has multiple second recesses evenly distributed. A spring is connected between the corresponding second recess and the first recess. This facilitates the installation of one end of the spring on the annular plate via the first recess and the installation of the other end of the spring inside the positioning disk via the second recess, thus facilitating the positioning disk's reset under the elastic action of the spring.

[0009] Optionally, the first end of the positioning rod has a cross-shaped groove, and the cross-shaped locking post is located inside the cross-shaped groove, which facilitates the placement of the first end of the positioning rod on the cross-shaped locking post through the cross-shaped groove. The second end of the positioning rod has a threaded hole, and a threaded rod is installed on one side of the positioning disk, which facilitates the installation of the threaded rod on one side of the positioning disk. One end of the threaded rod is threaded into the threaded hole, which facilitates the threaded rod being threaded into the second end of the positioning rod through the threaded hole. The outer wall of the positioning rod is equipped with multiple rubber protrusions, which facilitates the installation of the rubber protrusions on the outer wall of the positioning rod, thereby increasing the coefficient of friction between the outer wall of the positioning rod and the user's hand.

[0010] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0011] The positioning rod is designed to be positioned on one side of the radar body under the elasticity of the spring. This reduces the problem of the radar body shifting due to the impact of sand on the radar body when the autonomous vehicle is driving on uneven roads. The spring elasticity is used to correct the shifted radar body.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this embodiment provides a radar correction structure suitable for unmanned driving, including a housing 1, a radar body 2 on the housing 1, and a cross-shaped locking post 201 on one side of the radar body 2.

[0028] An annular plate 3 is threaded inside the housing 1. One end of the annular plate 3 is attached to one side of the radar body 2, which facilitates the positioning of the radar body 2 inside the housing 1 through the annular plate 3. It also facilitates the placement of the radar body 2 inside the housing 1 through the slot 101. The other side of the annular plate 3 is elastically and slidably fitted with a positioning disc 4, which is conveniently mounted on one side of the annular plate 3 by a spring 302. One end of the positioning disc 4 is threadedly fitted with a positioning rod 5, and one end of the positioning rod 5 is engaged with one end of the cross-shaped locking post 201.

[0029] When the radar body 2 needs to be installed, firstly, the positioning rod 5 is threaded onto one end of the threaded rod 402 through the threaded hole 501. Then, the radar body 2 is placed inside the housing 1 through the slot 101. Next, the annular plate 3 is threaded onto the inside of the threaded groove 102 through the external thread, and the radar body 2 is positioned inside the slot 101 through the annular plate 3. The positioning disk 4 moves through the spring 302 connected to the annular plate 3. The positioning disk 4 drives the positioning rod 5 to move through the threaded rod 402. Then, the positioning rod 5 is slid, and the positioning rod 5 drives the positioning disk 4 to move through the threaded rod 402 and stretches the spring 302. Then, one end of the positioning rod 5 is placed on the cross-shaped locking post 201 through the cross-shaped locking groove 502 and the positioning rod 5 is released. The positioning disk 4 is reset under the elastic action of the spring 302. The positioning disk 4 drives the positioning rod 5 to be positioned on the cross-shaped locking post 201 through the threaded rod 402, and thus the radar body 2 is installed inside the housing 1.

[0030] The positioning rod 5 is set so that it is positioned on one side of the radar body 2 under the elastic action of the spring 302. This reduces the problem of the radar body 2 being deviated due to the impact of sand when the unmanned vehicle is driving on uneven roads. The elasticity of the spring 302 is used to correct the radar body 2 when it is deviated.

[0031] In this embodiment, the housing 1 has a slot 101 and a threaded groove 102 that communicates with the radar body 2. The radar body 2 is located inside the slot 101. The outer side wall of the annular plate 3 has an external thread, which is threadedly engaged with the threaded groove 102. This facilitates the annular plate 3 to be threadedly engaged with the threaded groove 102 inside the housing 1. The inner side wall of the annular plate 3 has a plurality of first recesses 301 evenly distributed. The outer side wall of the positioning disk 4 has a plurality of second recesses 401 evenly distributed. The spring 302 is connected between the corresponding second recesses 401 and the first recesses 301. This facilitates the installation of one end of the spring 302 on the annular plate 3 through the first recess 301 and the other end of the spring 302 inside the positioning disk 4 through the second recesses 401. This facilitates the positioning disk 4 to be reset under the elastic action of the spring 302.

[0032] In this embodiment, the first end of the positioning rod 5 has a cross-shaped slot 502, and the cross-shaped locking post 201 is located inside the cross-shaped slot 502, which facilitates the placement of the first end of the positioning rod 5 on the cross-shaped locking post 201 through the cross-shaped slot 502. The second end of the positioning rod 5 has a threaded hole 501, and a threaded rod 402 is installed on one side of the positioning disk 4, which facilitates the installation of the threaded rod 402 on one side of the positioning disk 4. One end of the threaded rod 402 is threaded into the inside of the threaded hole 501, which facilitates the threaded rod 402 being threaded into the second end of the positioning rod 5 through the threaded hole 501. The outer wall of the positioning rod 5 is provided with multiple rubber protrusions, which facilitates the installation of the rubber protrusions on the outer wall of the positioning rod 5, thereby increasing the coefficient of friction between the outer wall of the positioning rod 5 and the user's hand.
