Technical Field

[0001] This utility model relates to the field of modern defense, and in particular to a base shield opening and closing device with an axis-driven translational structure. Background Technology

[0002] In the field of modern defense technology, base security is a crucial aspect. With the advancement of technology and the development of tactical requirements, traditional fixed or manually operated protective devices can no longer meet the requirements of rapid response and efficient protection.

[0003] Existing base shield opening and closing technologies mostly employ hydraulic or helical drive methods. While these methods achieve the shield's opening and closing function to a certain extent, they have many limitations. First, hydraulic systems are complex, have high maintenance costs, and their reliability decreases under extreme weather conditions. Second, although helical drive mechanisms are simple, their opening and closing speed is slow in the application of large shields, affecting reaction time. In addition, these traditional designs often neglect the adaptation to environmental factors (such as wind and shock waves), which greatly reduces the stability and safety of the device when facing real battlefield environments.

[0004] Therefore, it is necessary to provide a base shield opening and closing device with an axis-driven translation structure to solve the above-mentioned technical problems. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] First Embodiment

[0030] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a base shield opening and closing device with a shaft-driven translational structure provided by this utility model; Figure 2 for Figure 1 A three-dimensional structural diagram of the overall external structure of the device shown; Figure 3 for Figure 1 The diagram shows a three-dimensional internal structure of the device. A base shield opening and closing device employing an axis-driven translational structure includes:

[0031] Mounting frame 1, the surface of which is respectively provided with a bottom cover 2 and a protective cover 3;

[0032] Rotating assembly 5 is disposed inside the mounting frame 1. The rotating assembly 5 includes a rotating seat 51. A plurality of rotating rods 52 are rotatably connected to the surface of the rotating seat 51 via a rotating shaft. One end of the plurality of rotating rods 52 is rotatably connected to a push rod 53 via a rotating shaft.

[0033] A pushing device 4 is disposed inside the mounting frame 1 and located at one end of the pushing rod 53.

[0034] One end of the push rod 53 is connected to a rotating seat 54.

[0035] The pushing device 4 includes a fixed frame 41, and hydraulic telescopic rods 42 are connected to the left and right sides of the bottom of the fixed frame 41. The rotating seat 54 is connected to the fixed frame 41.

[0036] One end of the hydraulic telescopic rod 42 is connected to a push plate 43.

[0037] When the push plate 43 is pushed, the hydraulic telescopic rod 42 is activated to drive the push plate 43 to move.

[0038] When multiple pushing components 4 are pushed simultaneously, the rotating seat 51 drives multiple rotating rods 52 to rotate. When the multiple rotating rods 52 rotate, they drive the pushing rods 53 to move. When the pushing rods 53 move, they push the pushing components 4 to move through the rotating seat 54.

[0039] First, the device's rapid response capability was considered. In a competition, time is of the essence, and a shield that can open and close quickly can more effectively protect the base. Experimental tests revealed that the startup time of the axis-driven translational structure was significantly better than that of the helical drive system. For example, in a typical experiment, the average startup time of the axis-driven translational structure was 0.5 seconds, while the average startup time of the helical drive system was 1.2 seconds. This means that the axis-driven translational structure can protect the base much faster in emergency situations, demonstrating a significantly quicker response.

[0040] Secondly, stability is another crucial factor considered during the design phase. In combat, the base shield may face continuous impacts, thus stability directly affects the device's lifespan. Comparative testing revealed that the shaft-driven translational structure exhibits stronger impact resistance. For example, in simulated projectile impact experiments, the shaft-driven translational structure only experienced a 1% decrease in stability after withstanding 1000 consecutive impacts, while the helical-driven structure showed a 5% decrease. This demonstrates that the shaft-driven translational structure can withstand sustained impacts better, thus providing superior base protection.

[0041] Compared with related technologies, the base shield opening and closing device with a shaft-driven translation structure provided by this utility model has the following advantages:

[0042] This utility model provides a base shield opening and closing device with an axis-driven translational structure. A rotating component 5 and a pushing device 4 are respectively set on the mounting frame 1 with a bottom cover 2 and a protective cover 3. Through precise calculation and optimized layout, high-efficiency power transmission and smooth opening and closing action can be achieved. The device uses one or more sets of axis drive systems in conjunction with a slide rail translation mechanism to ensure the synchronization and stability of the shield during the opening and closing process. At the same time, this design simplifies the structure, reduces the weight of the device, and improves the energy efficiency ratio and ease of operation.

The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0045] Specifically, the second embodiment of this application provides a base shield opening and closing device with an axis-driven translational structure. The difference is that, in a base shield opening and closing device with an axis-driven translational structure, a splicing component 6 and a fixing component 7 are respectively provided between the bottom cover 2 and the protective cover 3. The splicing component 6 includes an annular splicing block 61, and the top of the bottom cover 2 is provided with an annular splicing groove 62 that is adapted to the annular splicing block 61.

[0046] The fixing component 7 includes an external thread fixing block 71, and the bottom of the protective cover 3 is provided with a mounting through hole 72 that is adapted to the external thread fixing block 71.

[0047] The annular splicing block 61 is connected to the bottom of the protective cover 3. The use of the annular splicing block 61 and the annular splicing groove 62 facilitates the positioning of the bottom cover 2 and the protective cover 3 during installation.

[0048] The surface of the external threaded fixing block 71 is threadedly connected to a threaded sleeve 73.

[0049] The external threaded fixing block 71 is connected to the top of the bottom cover 2.

[0050] The working principle of the base shield opening and closing device with a shaft-driven translational structure provided by this utility model is as follows:

[0051] When using, when disassembling the bottom cover 2 and the mounting cover 3, first remove the threaded sleeve 73 on the surface of the external threaded fixing block 71. After the threaded sleeve 73 is removed, pull the mounting cover 3 to separate the mounting through hole 73 from the external threaded fixing block 71.

[0052] Compared with related technologies, the base shield opening and closing device with a shaft-driven translation structure provided by this utility model has the following advantages:

[0053] This utility model provides a base shield opening and closing device with a shaft-driven translation structure. A splicing component 6 and a fixing component 7 are set between the bottom cover 2 and the protective cover 3 so that the internal components of the device can be easily disassembled and inspected when they malfunction.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
