Description

Technical Field

[0001] This utility model relates to the field of navigation data recorder technology, and in particular to a shipborne navigation data recorder. Background Technology

[0002] A ship's navigation data recorder, commonly known as a marine black box, records the ship's status, equipment operation, and bridge voice recordings in real time. This provides objective evidence for reconstructing the events of an accident, changing the way investigations are conducted and improving efficiency. Existing navigation data recorders can record both ship data and voice data. Ship data recording primarily collects and records operational data, navigation data, status data, and fixed data; voice data recording collects and records audio signals from inside and outside the bridge, as well as VHF communication audio signals. Accurate recording and preservation of this data is crucial. Data storage is a key component of the data recorder, capable of recording information transmitted from radar and other equipment. Its reliability and shock resistance directly determine the reliability and effectiveness of the "black box."

[0003] However, some current flight data recorders often employ a robust, sealed, integrated structure to protect the stability of their internal electronic components. The electronic components are rigidly connected to the housing, relying on the high strength of the housing for protection. This protective structure is complex, inconvenient to disassemble, and lacks corresponding shock-absorbing structures due to the frequent ups and downs during flight, making it relatively more susceptible to structural damage from vibration. Utility Model Content

[0004] This invention provides a shipborne navigation data recorder, which helps to solve the problem that some existing shipborne navigation data recorders do not have a suitable shock absorption structure, resulting in the internal electronic components being easily damaged by vibration.

[0005] This utility model is implemented as follows:

[0006] The shipborne navigation data recorder includes a housing with a mounting groove at the bottom. The mounting groove is detachably connected to a cover plate. An inner cavity is provided inside the mounting groove, and an inner shell is installed in the inner cavity. The inner shell is used to install navigation data storage electronic components. A buffer gap is left between the inner shell and the outer shell. Several strip-shaped buffer components are provided in the buffer gap. The buffer components are made of elastic material. The cross-sectional outline of the short side of the buffer component is a "D" shape. One side of the buffer component has a flat part that abuts against the outer wall of the inner shell. The other side of the buffer component has an arched part that abuts against the inner wall of the outer shell. A support part is provided between the flat part and the arched part. The buffer component is located on both sides of the support part to form a first cavity.

[0007] Based on the above technical solution, the support part is an elastic plate structure parallel to the short side direction of the buffer, and the inner and outer ends of the support part are respectively connected and fixed to the outer side wall of the flat part and the inner side wall of the arched part.

[0008] Based on the above technical solution, the buffer component is composed of a flattening part, an arched part, and a supporting part forming an integrated structure.

[0009] Based on the above technical solution, the leveling part is provided with a supporting part in the inner region of the first cavity. One end of the supporting part is perpendicularly connected to the leveling part, and the other end of the supporting part is a free end facing the arched part.

[0010] Based on the above technical solution, there is a gap between the free end of the supporting part and the arching part.

[0011] Based on the above technical solution, several supporting parts are arranged at intervals within the first cavity.

[0012] Based on the above technical solution, the support part is provided with a pleated part, which is composed of a number of flange structures of different sizes arranged linearly.

[0013] Based on the above technical solution, a second cavity is provided on the inner side of the folded part.

[0014] Based on the above technical solution, the first cavity is filled with a filling material.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] This invention features a double-layered protective structure consisting of an outer shell and an inner shell, providing sufficient rigid structural support to support and protect the electronic components used for data storage during navigation. Furthermore, by incorporating a buffer gap and buffer components between the outer and inner shells, this invention adds a buffer structure compared to some existing shipborne navigation data recorders. This structure effectively dampens and buffers vibrations caused by undulations during navigation, reducing the impact on the structural stability of the internal electronic components and thus achieving a greater degree of shock absorption and protection.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0026] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Example 1: Combination Figure 1-4 This embodiment discloses a shipborne navigation data recorder, specifically including a rectangular shell structure, the outer shell 1. The outer shell 1 serves as the external structure of the shipborne navigation data recorder, providing basic protection for the internal structure. The outer shell 1 is also used for connection and installation at a specific mounting position on the ship, effectively securing the recorder. The bottom of the outer shell 1 has a mounting groove 11, forming an opening structure to facilitate the disassembly and assembly of internal components. A cover plate 2 is detachably connected to the mounting groove 11 via bolts. The cover plate 2 seals the mounting groove 11, effectively protecting the interior. It should be noted that a sealing gasket is provided in the connection gap between the cover plate 2 and the mounting groove 11, and the connecting parts (bolts, etc.) are also equipped with corresponding sealing gaskets, giving the internal space of the outer shell 1 excellent sealing and waterproofing.

[0030] The mounting slot 11 has an inner cavity on its inner side, which serves as a loading space. The inner shell 3 is installed in the inner cavity, and the inner shell 3 is used to install navigation data storage electronic components. Therefore, the inner shell 3 and the outer shell 1 form a double-wrap protective structure.

[0031] Furthermore, a buffer gap 4 is provided between the inner shell 3 and the outer shell 1. Several strip-shaped buffer elements 5 are provided in the buffer gap 4. The buffer elements 5 are evenly distributed between the inner shell 3 and the outer shell 1. The buffer elements 5 are made of elastic material (rubber) and serve as a buffer structure between the inner shell 3 and the outer shell 1. When the external environment shakes, the buffer elements 5 can absorb and weaken the shaking to a certain extent, further improving the stability of the internal structure.

[0032] Specifically, in combination Figure 3 and Figure 4The buffer member 5 has a "D"-shaped cross-sectional profile along its short side. One side of the buffer member 5 has a flat portion 51 that abuts against the outer wall of the inner shell 3, and the other side has an arched portion 52 that abuts against the inner wall of the outer shell 1. A support portion 53 is provided between the flat portion 51 and the arched portion 52, and the buffer member 5 forms a first cavity 54 on both sides of the support portion 53. The flat portion 51 is glued to the outer wall of the inner shell 3, ensuring that the installation position of the buffer member 5 remains fixed.

[0033] Furthermore, the support portion 53 is an elastic plate structure parallel to the short side of the buffer member 5, and its inner and outer ends are respectively connected and fixed to the outer side wall of the flattening portion 51 and the inner side wall of the arched portion 52. In this embodiment, the buffer member 5 is composed of a flattening portion 51, an arched portion 52, and a support portion 53 forming an integrated structure. This makes the overall connection between the various parts of the buffer member 5 strong, and it can promptly transmit and disperse force when subjected to external force. Figure 4 As shown, when subjected to compressive force, the arched part 52 is squeezed inward, thereby compressing the support part 53. The support part 53 uses its own elasticity to convert part of the force into elastic deformation, which reduces the compressive force and thus provides shock absorption protection for the internal structure.

[0034] Example 2: Based on Example 1, combined with Figure 5 As shown, in this embodiment, the flattening part 51 is provided with a supporting part 55 in the inner region of the first cavity 54. One end of the supporting part 55 is vertically connected to the flattening part 51, and the other end of the supporting part 55 is a free end facing the arched part 52.

[0035] Furthermore, there is a gap between the free end of the support portion 55 and the arched portion 52. The two support portions 55 are spaced apart within the first cavity 54. The function of the support portions 55 is to add an additional auxiliary support structure, so that the buffering process has two stages. In the initial stage of compression, only the contraction of the support portion 53 is used for buffering. In the later stage of compression, the support portion 55 participates, providing a more sufficient elastic support effect, and avoiding excessive compression of the buffer member 5 so that the external force is directly transmitted to the internal structure.

[0036] Example 3: Based on Example 1, combined with Figure 6 As shown, in this embodiment, the support portion 53 is provided with a pleated portion 56, which is composed of a number of flange structures of different sizes arranged linearly. Furthermore, a second cavity 57 is provided inside the pleated portion 56, which makes the structure of the support portion 53 more complex, improves its elasticity, and enables it to buffer and dampen more slight external shaking.

[0037] In other embodiments, the first cavity 54 can be further enhanced by filling it with a suitable filler material, such as filling it with a suitable elastic ball, which can further enhance the buffering effect of the buffer 5.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
