A LiDAR pod is an aviation device that integrates a LiDAR system. It is usually installed on drones, helicopters, or other aircraft. In order to ensure the normal use of the radar, a protective mechanism for the pod is required.

[0003] However, most of the protective mechanisms inside rotating lidar pods in the existing technology use an external metal frame for the radar, which is heavy during use and increases the load on the drone.

[0004] Therefore, a protective mechanism is needed inside the rotating lidar pod. Utility Model Content

[0005] This utility model proposes a protective mechanism for the internal structure of a rotating lidar pod, which solves the problem that existing protective mechanisms for rotating lidar pods mostly use an external metal frame for the radar, resulting in heavy weight and increased load on the UAV during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0011] Preferably, the protective rings are arranged in a spherical array outside the inner protective shell, and the centers of the inner protective shell and the protective rings coincide with each other.

[0012] Preferably, the anti-collision cotton and the inner protective shell are fixed to each other, and the laser body is matched with the inner wall of the anti-collision cotton through a limiting groove.

[0013] Preferably, the rear protective shell forms a sealed structure with the front protective shell through a positioning plate.

[0014] Preferably, the contact surfaces between the positioning plates are sized to match and fit tightly together.

[0015] Preferably, the front protective shell is mutually sealed to the laser body through a sealing ring.

[0016] This utility model proposes a protective mechanism for a rotating lidar pod. Compared with the prior art, the advantages of this utility model are:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides a technical solution: a protective mechanism inside a rotating lidar pod, comprising a rear protective shell 1 and a rear protective assembly installed inside the rear protective shell 1, wherein the rear protective assembly includes a support truss 2;

[0027] A support truss 2 is fixedly installed on the inner wall of the rear protective shell 1. A protective ring 3 is fixedly installed on the side of the support truss 2. An inner protective shell 4 is fixedly installed at the other end of the support truss 2. An anti-collision cotton 5 is fixedly installed on the inner wall of the inner protective shell 4. A limit groove 6 is opened on the inner wall of the anti-collision cotton 5. A positioning plate 7 is fixedly installed on the outside of the support truss 2.

[0028] Furthermore, rotating mounting brackets 8 are fixedly installed on the left and right sides of the positioning plate 7, a laser body 9 is tightly installed inside the anti-collision cotton 5, a front protective shell 10 is installed in front of the rear protective shell 1, a laser body 9 is installed at the position where the front protective shell 10 contacts the laser body 9, a fixing bolt 11 is installed on the surface of the rotating mounting bracket 8, and a sealing ring 12 is provided on the surface of the laser body 9.

[0029] Furthermore, the support truss 2 array is installed on the inner wall of the rear protective shell 1. The support truss 2 has an "eight" shaped structure and is fixed to the inner protective shell 4. The support truss 2 is made of lightweight material. During use, the support truss 2's "eight" shaped structure can support the inner protective shell 4 inside the device, creating space between the inner protective shell 4 and the rear protective shell 1. This improves the strength of the device and enhances the shock resistance of the laser body 9 inside the device, thus improving the protection of the laser body 9. At the same time, the array distribution of the support truss 2 inside the rear protective shell 1 makes the device more stable. In addition, the lightweight material of the support truss 2 reduces the overall weight of the device, making it convenient to use.

[0030] Furthermore, the protective rings 3 are arranged in a spherical array outside the inner protective shell 4, with the centers of the inner protective shell 4 and the protective rings 3 coinciding with each other. The protective rings 3 are also arranged in an array outside the inner protective shell 4. Therefore, the inner protective shell 4 is further protected on the basis of the supporting truss 2, which improves the stability of the device and prevents the internal laser body 9 from being damaged and affecting the use of the device.

[0031] Furthermore, the anti-collision cotton 5 and the inner protective shell 4 are fixed to each other. The laser body 9 is matched with the inner wall of the anti-collision cotton 5 through the limiting groove 6. The anti-collision cotton 5 is fixed to each other inside the inner protective shell 4, which can protect the laser body 9 and prevent the laser body 9 from colliding with the inner protective shell 4 when the device is impacted, thus avoiding damage to the device and affecting its use. At the same time, the matching size between the laser body 9 and the inner wall of the anti-collision cotton 5 can prevent the laser body 9 from shaking inside the device.

[0032] Furthermore, the rear protective shell 1 forms a sealed structure with the front protective shell 10 through the positioning plate 7; during use, the rear protective shell 1 and the front protective shell 10 are installed together through the positioning plate 7, and then the laser body 9 is installed inside the anti-collision cotton 5 to facilitate the protection of the laser body 9. During installation, the two positioning plates 7 are fixed together to prevent external moisture and other substances from entering the device and causing damage during use.

[0033] Furthermore, the contact surfaces between the positioning plates 7 are sized and fit tightly together. During use, the rear protective shell 1 and the front protective shell 10 are installed together through the positioning plates 7, and then the laser body 9 is installed inside the anti-collision cotton 5 to facilitate the protection of the laser body 9. During installation, the two positioning plates 7 are fixed together to prevent external moisture and other substances from entering the device and causing damage during use.

[0034] Furthermore, the front protective shell 10 is sealed to the laser body 9 by the sealing ring 12. The front of the laser body 9 explores the external environment. At this time, the front protective shell 10 is installed around the outside of the laser body 9 by the sealing ring 12. At the same time, the sealing ring 12 and the laser body 9 are sealed to each other, which can prevent external moisture from entering the device through the gap between the front protective shell 10 and the laser body 9 during the use of the device and affecting the use of the device.

[0035] Working principle: First, the laser body 9 is installed inside the anti-collision cotton 5. The anti-collision cotton 5 is fixed inside the inner protective shell 4, protecting the laser body 9 and preventing it from colliding with the inner protective shell 4 when the device is impacted, thus avoiding damage to the device and affecting its use. At the same time, the dimensions of the laser body 9 and the inner wall of the anti-collision cotton 5 match, preventing the laser body 9 from shaking inside the device. Meanwhile, the supporting truss 2 has a V-shaped structure, which supports the inner protective shell 4 inside the device, creating space between the inner protective shell 4 and the rear protective shell 1. This increases the strength of the device and enhances the laser's internal performance. The shock resistance of body 9 is improved, enhancing the protection of laser body 9. At the same time, the array distribution of the supporting truss 2 inside the rear protective shell 1 also makes the device more stable. Then, the front protective shell 10 is installed together with the rear protective shell 1, and the two positioning plates 7 are fixed together to prevent external moisture from entering the device and causing damage during use. At this time, the front protective shell 10 is installed around the outside of the laser body 9 through the sealing ring 12. At the same time, the sealing ring 12 and the laser body 9 are mutually sealed, which can prevent external moisture from entering the device through the gap between the front protective shell 10 and the laser body 9 during use and affecting the use of the device.
