Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective structure technology, specifically to an aviation aluminum alloy outer shell protective plate. Background Technology
[0002] Due to the complexity of aircraft structures, the variety and quantity of various components, and the fact that most small parts have low rigidity under their own weight, while the quality of assembly has strict technical requirements, in order to ensure safety, the protection of important components is strengthened by adding side guards, etc. The current exhaust connection side guard is an integral steel component with a reinforced rib structure on the surface, which enhances the strength and rigidity of the workpiece, but at the same time causes the disadvantages of excessive weight and difficulty in heat dissipation due to complete enclosure.
[0003] Utility model patent CN210761333U discloses an aviation connecting side guard plate. This design features a side guard plate body with a central heat dissipation section containing heat dissipation holes. One side of the side guard plate body has a positioning section with a first positioning pin hole and a second positioning pin hole below it. Adjacent to the positioning section is a connecting section with a first connecting groove, a first connecting plate, a second connecting groove, and a second connecting plate. Both the first and second connecting plates have connecting holes. The structure is simple, ensuring both the strength of the protective plate and sufficient heat dissipation, while also ensuring uniform stress distribution and preventing deformation.
[0004] However, the above solutions still have some shortcomings. One issue is that these solutions only increase the heat dissipation area of the heat dissipation structure by creating ventilation holes. However, when high-speed airflow flows along the heat dissipation structure, the airflow cannot reach the inside of the ventilation holes. Therefore, increasing the number of ventilation holes has a limited effect on improving the heat dissipation efficiency of the heat dissipation structure. In view of this, we propose an aerospace aluminum alloy outer shell cover. Utility Model Content
[0005] The purpose of this utility model is to provide an aviation aluminum alloy shell protective plate. This aviation aluminum alloy shell protective plate solves the problem that in the prior art, the heat dissipation area of the heat dissipation structure is increased by simply opening heat dissipation holes. However, when high-speed airflow flows along the heat dissipation structure, the airflow cannot flow into the heat dissipation holes. Therefore, the increase of heat dissipation holes has a limited effect on improving the heat dissipation efficiency of the heat dissipation structure.
[0006] To achieve the above objectives, this utility model provides the following technical solution: An aviation aluminum alloy outer shell protective plate, comprising an outer shell; The outer shell is connected to a protective plate body, and the protective plate body is provided with a heat dissipation mechanism. The heat dissipation mechanism includes a mounting frame, which is fixedly connected to the outside of the protective plate body. A heat dissipation plate is rotatably connected to the inside of the mounting frame, and a drive rod is slidably connected to the inside of the mounting frame. A connecting rod is rotatably connected to the end of the drive rod, and the end of the connecting rod is rotatably connected to the heat dissipation plate.
[0007] Preferably, a heat dissipation fin is rotatably connected to the heat dissipation plate, the heat dissipation fin is equidistantly arranged on the heat dissipation plate, and both the heat dissipation plate and the heat dissipation fin have a streamlined structure.
[0008] Preferably, an oscillating spring is fixedly connected to the inner side of the heat dissipation fin, and the end of the oscillating spring is fixedly connected to the heat dissipation plate.
[0009] Preferably, a handle is fixedly connected to the side of the guard plate body. The handle has an arc-shaped structure and an anti-slip groove is provided on the handle.
[0010] Preferably, the protective plate body is provided with an installation mechanism, the installation mechanism includes an installation block, the installation block is slidably connected to the installation frame, the installation block is internally engaged with an installation bolt, and the outer shell is provided with screw holes corresponding to the structure of the installation bolt.
[0011] Preferably, the outer casing has a positioning groove, a positioning block is movably connected in the positioning groove, an installation rod is rotatably connected to the outside of the positioning block, and the end of the installation rod is rotatably connected to the installation block.

[0013] By employing the above technical solution, this utility model provides an aviation aluminum alloy outer shell protective plate. It possesses at least the following beneficial effects: (1) The present invention uses multiple sets of streamlined heat dissipation fins to draw the heat dissipation fins outward by using the negative pressure generated by the high-speed airflow when the airflow passes by, so that the heat dissipation structure can quickly increase the heat dissipation area. At the same time, after the heat dissipation fins rotate outward and unfold, they block the airflow. Under the action of the airflow, they rotate inward and close again, so that the heat dissipation fins form a cycle between unfolding heat dissipation and closing heat storage, thereby improving the heat dissipation effect of the heat dissipation plate.
[0014] (2) The installation structure of this utility model, through the linkage structure, allows the heat sink to be rotated outward from inside the installation frame while the protective plate body is installed on the outer shell, thereby improving the opening efficiency of the heat sink structure, reducing the amount of operation required by the operator in installing the protective plate body, and improving the installation efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0018] Example 1 An aviation aluminum alloy outer shell protective plate, such as Figures 1-5As shown, the device includes an outer shell 1; a protective plate body 2 is connected to the outer shell 1, and a heat dissipation mechanism 3 is provided on the protective plate body 2. The heat dissipation mechanism 3 includes a mounting frame 301, which is fixedly connected to the outside of the protective plate body 2. A heat dissipation plate 302 is rotatably connected to the inside of the mounting frame 301, and a drive rod 303 is slidably connected to the inside of the mounting frame 301. A connecting rod 304 is rotatably connected to the end of the drive rod 303, and the end of the connecting rod 304 is rotatably connected to the heat dissipation plate 302. The protective plate body 2 can protect and dissipate heat from the outer shell 1, improving the heat dissipation effect of the outer shell 1 while preventing damage to the outer shell 1 caused by external impacts. The heat dissipation mechanism 3 can improve the heat dissipation effect of both the protective plate body 2 and the outer shell 1. The mounting frame 301 can fix the heat dissipation mechanism 3 onto the protective plate body 2. The heat dissipation plate 302 inside the mounting frame 301 can rotate outward and unfold after installation, thereby increasing the heat dissipation area of the mounting plate and thus improving the heat dissipation efficiency and effect. The drive rod 303 structure can drive the heat dissipation plate 302 to unfold. The connecting rod 304 structure at the end of the drive rod 303 can drive the heat dissipation plate 302, so that one side of the heat dissipation plate 302 can rotate outward and open. Heat dissipation fins 305 are rotatably connected to the heat dissipation plate 302. The heat dissipation fins 305 are equidistantly arranged on the heat dissipation plate 302. Both the heat dissipation plate 302 and the heat dissipation fins 305 are streamlined. The streamlined heat dissipation fins 305 utilize the negative pressure generated by the high-speed airflow on their sides to drive them outwards, allowing them to open automatically during use and dissipate heat internally. Once fully deployed, the fins block the airflow and rotate inwards again under the influence of the airflow, creating a oscillating motion that rapidly dissipates heat from the outer shell 1 and the protective plate body 2. An oscillating spring 306 is fixedly connected to the inner side of the heat dissipation fins 305, with its end fixedly connected to the heat dissipation plate 302. When the heat dissipation fins 305 are subjected to airflow... After opening outward under the negative pressure of the airflow, the heat dissipation fins 305 stretch the inner oscillation springs 306. Combined with the impact of the airflow on the heat dissipation fins 305, the heat dissipation fins 305 can rebound. At the same time, multiple sets of equidistantly arranged heat dissipation fins 305, together with the oscillation springs 306, can protect against external impacts, thereby reducing the damage caused by the impact of foreign objects on the outer shell 1. A handle 4 is fixedly connected to the side of the protective plate body 2. The handle 4 has an arc-shaped structure and an anti-slip groove 5. The handle 4 structure can facilitate the installation of the protective plate body 2 onto the outer shell 1, or the movement of the protective plate body 2 through the handle 4. At the same time, the anti-slip groove 5 structure can facilitate the operator to grip the protective plate body 2.
[0019] Example 2 like Figures 1-4As shown, the protective plate body 2 is provided with an installation mechanism 6, which includes an installation block 601. The installation block 601 is slidably connected to the installation frame 301, and an installation bolt 602 is engaged inside the installation block 601. The outer shell 1 has screw holes 603 corresponding to the structure of the installation bolt 602. The installation mechanism 6 can easily install the protective plate body 2 onto the outer shell 1. The structure of the installation block 601 can accommodate the installation bolt 602. The installation bolt 602 can cooperate with the screw holes 603 to fix the protective plate body 2 to the outer shell 1. The outer shell 1 has a positioning groove 604, and a positioning block 605 is movably connected in the positioning groove 604. An installation rod 606 is rotatably connected to the outside of the positioning block 605. The end of the installation rod 606 is rotatably connected to the installation block 601. The structure of the positioning groove 604 can assist in positioning the protective plate body 2 and prevent the protective plate body 2 from being positioned. After installation and fixing, if a misalignment occurs, the positioning groove 604 is opened on both sides of the screw hole 603. During the installation of the mounting block 601, the positioning block 605 can be moved into the positioning groove 604 by the mounting rod 606, thereby realizing the tight fixing operation of the protective plate body 2. The mounting block 601 is fixedly connected to the side of the ejector block 607. The side of the ejector block 607 is an arc-shaped structure. The end of the drive rod 303 is an arc-shaped structure corresponding to the structure of the ejector block 607. The drive rod 303 is arranged adjacent to the ejector block 607. The structure of the ejector block 607 can enable the mounting mechanism 6 and the heat dissipation mechanism 3 to be linked. When the mounting block 601 is installed and fixed by the mounting bolt 602, the mounting block 601 moves inward and can be driven by the ejector block 607 on the side to drive the drive rod 303, so that the drive rod 303 slides laterally and adjusts. When moving, the heat dissipation plate 302 is rotated and opened by the connecting rod 304.
[0020] In use, the aerospace aluminum alloy outer shell protective plate of this utility model is moved to the surface of the outer shell 1 to be installed, and the mounting bolt 602 is rotated inward. The mounting bolt 602 then moves from the mounting block 601 into the screw hole 603 of the outer shell 1, and drives the mounting block 601 towards the outer shell 1. The mounting block 601 then pushes the positioning block 605 into the positioning groove 604 through the mounting rod 606. The mutual cooperation between the mounting block 601 and the mounting groove improves the installation firmness of the protective plate body 2. While the mounting block 601 is moving, the push-out block 607 on the side can push the drive rod 303 to move, so that the drive rod 303 continuously moves away from the mounting block 601 in the direction of the drive rod 303. The drive rod 303 then drives the heat sink 302 to rotate outward through the connecting rod 304. During use, the airflow flows along the heat sink 302, which can quickly dissipate the heat transferred by the heat sink 302. At the same time, the streamlined structure heats the heat sink. Plate 302 can increase the airflow velocity on the surface of heat sink 302, and use the negative pressure generated by the high-speed airflow to draw the heat sink 305 outward. After the heat sink 305 is deployed, it can increase the surface area of heat sink 302, thereby improving the heat dissipation efficiency of heat sink 302. In addition, after the heat sink 305 is deployed, it blocks the airflow on the surface of heat sink 302. The airflow then impacts the heat sink 305, and the elastic force formed by stretching the oscillating spring 306 after the heat sink 305 rotates outward causes the heat sink 305 to rotate inward again. The continuous reciprocating oscillation of the heat sink 305 can allow the heat sink 305 to fan out the heat accumulated inside heat sink 302, thereby further improving the heat dissipation effect of heat sink 302. When heat sink 302 is impacted by hail or high-speed water droplets, the heat sink 305 can buffer the impact through the elasticity of the inner oscillating spring 306, thereby reducing the impact on the outer shell 1 and extending the service life of the outer shell 1.
