Technical Field
[0001] This utility model relates to the field of navigation modules, and more particularly to an anti-interference BeiDou or GNSS dual-mode navigation module. Background Technology
[0002] In numerous fields such as modern transportation, geological exploration, and intelligent driving, high-precision positioning and navigation information is one of the core elements ensuring the efficient and safe operation of various tasks. Anti-interference BeiDou or GNSS dual-mode navigation modules are crucial devices for providing this critical information. With the continuous expansion of application scenarios, these modules often need to operate in complex and ever-changing environments, such as the bumps of vehicles, the severe vibrations of construction machinery, and the impacts and collisions during field exploration. These external vibrations and impacts can easily interfere with the normal operation of the modules. Therefore, improving the modules' anti-interference capabilities in vibration environments and ensuring their positioning accuracy and operational stability has become an important direction for technological development in this field.
[0003] In existing technologies, vibration reduction and protection for navigation modules typically employ basic mechanical structures. For example, some devices use a simple metal casing around the module, utilizing the rigidity of the metal itself to withstand minor external impacts; others use a single spring structure, absorbing some vibration energy through the elastic deformation of the spring; or ordinary foam pads or sponge pads are used as cushioning materials, filling the space between the module and the mounting base, relying on the elasticity of these materials to reduce the impact of vibration on the module. The underlying principle is primarily to attempt to block or dissipate the vibration energy transmitted to the module from the outside world through a single vibration reduction or cushioning method. However, the mechanical structures and protection methods used in existing technologies have limited absorption and buffering effects on lateral vibrations and bottom impacts under complex working conditions. They are difficult to attenuate interference from external vibrations in an all-round and effective manner, often leading to inaccurate navigation data and reduced positioning accuracy of navigation modules in vibration environments. Therefore, anti-interference BeiDou or GNSS dual-mode navigation modules are proposed to solve the above problems. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides an anti-interference BeiDou or GNSS dual-mode navigation module, which aims to improve the problem of inaccurate navigation data and decreased positioning accuracy caused by mechanical vibration or impact interference.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An anti-interference BeiDou or GNSS dual-mode navigation module includes a navigation module, the outer wall of which is provided with a protective shell, the inside of which is provided with a stabilizing component, the bottom of which is provided with a fixing plate, and a quick-release component is provided between the fixing plate and the navigation module; The quick-release assembly includes multiple locking plates located inside the fixing plate. A connecting plate is fixedly connected to the outer wall of the protective shell. Multiple connecting posts are slidably connected inside the connecting plate.

[0008] As a further description of the above technical solution: The stabilizing component includes multiple springs II, which are located on the outer wall of the navigation module, and multiple connecting plates II are fixedly connected to the inner wall of the protective shell.
[0009] As a further description of the above technical solution: Each of the navigation modules has multiple rubber pads fixedly connected to its outer side wall, and the multiple rubber pads are slidably connected to the inner wall of the protective shell.

[0013] This utility model has the following beneficial effects: 1. In this utility model, through a three-dimensional vibration reduction and protection structure, lateral vibrations are absorbed and buffered by the dual action of spring two and rubber pad two, while impacts at the bottom are effectively attenuated by rubber pad one.

It solves the problem of inaccurate navigation data and reduced positioning accuracy caused by mechanical vibration or impact interference, and enhances the anti-interference ability and overall reliability of the navigation module under complex working conditions.
[0014] 2. In this utility model, by setting up a quick-release component, the navigation module can be quickly installed and disassembled.

[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] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of an anti-interference Beidou or GNSS dual-mode navigation module, including a navigation module 1. The outer wall of the navigation module 1 is provided with a protective shell 2, which is used to protect the internal navigation module 1 from external physical impacts. The protective shell 2 is provided with a stabilizing component inside, which is used to absorb and buffer vibrations to ensure the stability of the navigation module 1. The bottom of the navigation module 1 is provided with a fixing plate 4, which is used to provide an installation base. A quick-release component is provided between the fixing plate 4 and the navigation module 1, which is used to realize the quick installation and disassembly of the navigation module 1. This solves the problem of complex, time-consuming and laborious installation and disassembly by traditional screw fixing method, and significantly enhances the convenience of quick replacement and maintenance on site. The quick-release assembly includes multiple locking plates 8 located inside the fixing plate 4. A connecting plate 3 is fixedly connected to the outer wall of the protective shell 2. Multiple connecting posts 6 are slidably connected inside the connecting plate 3. Each connecting post 6 has a slip ring 16 fixedly connected to its outer wall. The slip ring 16 reduces the frictional resistance when the connecting post 6 slides inside the connecting plate 3, enhancing the smoothness of operation. The multiple slip rings 16 are slidably connected to the surface of the sealing groove inside the connecting plate 3. The bottom of each connecting post 6 is fixedly connected to the top of the locking plate 8. A handle 7 is fixedly connected to the top of each connecting post 6. The handle 7 cooperates with the connecting post 6 for pressing and rotating operations, achieving manual control of locking and unlocking of the quick-release assembly. The multiple locking plates 8 cooperate with the grooves inside the fixing plate 4 for rotating engagement. The entire device is locked onto the fixed plate 4. Each locking plate 8 has a push assembly at its bottom, which provides a reverse elastic force to achieve automatic locking of the locking plate 8. Each push assembly includes a spring 11, which stores and releases elastic potential energy to provide power for the rebound locking of the locking plate 8. Each spring 11 is located at the bottom of the locking plate 8. Multiple fixing posts 10 are fixedly connected inside the fixed plate 4. Each fixing post 10 has a sliding post 9 slidably connected to its inner wall. The sliding post 9 slides up and down in cooperation with the fixing post 10, providing a stable guide for the compression and recovery of the spring 11. The top of each spring 11 is fixedly connected to the bottom of the sliding post 9, and the bottom of each spring 11 is fixedly connected to the bottom of the inner wall of the fixing post 10.
[0019] Reference Figures 1-3The stabilizing component is used to absorb and buffer vibrations from the outside in all directions, solving the problem of inaccurate navigation data and decreased positioning accuracy caused by mechanical vibration or impact interference. It enhances the anti-interference capability and overall reliability of the navigation module 1 under complex working conditions. The stabilizing component includes multiple springs 14 located on the outer wall of the navigation module 1. Multiple connecting plates 13 are fixedly connected to the inner wall of the protective shell 2, providing stable fixing points for the springs 14. Multiple rubber pads 15 are fixedly connected to the outer wall of each navigation module 1. These rubber pads 15 slide against the inner wall of the protective shell 2, and their flexible material, together with the springs 14, dampes lateral vibrations, achieving a dual vibration reduction effect. One end is fixedly connected to one side of the connecting plate 2 13, and the other end of multiple springs 2 14 is fixedly connected to one side of the rubber pad 2 15. The multiple springs 2 14 work together with the connecting plate 2 13 and the rubber pad 2 15 to elastically expand and contract, achieving the effect of absorbing and buffering lateral vibration energy. A rubber pad 1 12 is provided at the bottom of the protective shell 2. The rubber pad 1 12 uses its softness to reduce and absorb the vibration force transmitted from the fixed plate 4 to the bottom of the navigation module 1, achieving the effect of buffering the bottom impact. The bottom of the rubber pad 1 12 is fixedly connected to the inner wall of the top groove of the fixed plate 4. A baffle 5 is fixedly connected to the top of the protective shell 2. The baffle 5 is used to limit and protect the top of the navigation module 1 to prevent it from displacing too much during severe vibration. The bottom of the baffle 5 is in contact with the top of the navigation module 1.
[0020] Working principle: When installing navigation module 1, first press down on handle 7. Handle 7 moves the bottom locking plate 8 downwards via connecting post 6. Simultaneously, the slip ring 16 on the outer wall of connecting post 6 slides on the groove surface inside connecting plate 3. When locking plate 8 moves downwards, it pushes the sliding post 9 below it to slide inside the fixing post 10, thereby compressing the spring 11 inside the fixing post 10. Next, rotate handle 7 90 degrees, causing locking plate 8 to rotate 90 degrees as well. At this point, release handle 7. Under the elastic restoring force of spring 11, the sliding post 9 and locking plate 8 will be pushed upwards. Since locking plate 8 has rotated, it will engage with the edge of the groove inside the fixing plate 4, thus firmly locking the entire device onto the fixing plate 4. This completes the quick installation, solving the problems of complex, time-consuming, and labor-intensive installation and disassembly using traditional screw fixing methods, and significantly enhancing the efficiency of modern installation. The system offers convenient quick replacement and maintenance. During operation, vibrations from the external environment are transmitted through the fixed plate 4 and the protective shell 2. For lateral vibrations, multiple springs 14 between the connecting plate 13 on the inner wall of the protective shell 2 and the rubber pad 15 on the side wall of the navigation module 1 effectively absorb and buffer them. At the same time, the flexible material of the rubber pad 15 itself can further attenuate the vibrations. For vibrations from the bottom, the rubber pad 12 laid between the protective shell 2 and the fixed plate 4 provides buffering. This three-dimensional vibration reduction structure can protect the internal navigation module 1 in all directions, ensuring its working stability in a vibration environment. It solves the problem of inaccurate navigation data and decreased positioning accuracy caused by mechanical vibration or impact interference, and enhances the anti-interference ability and overall reliability of the navigation module 1 under complex working conditions.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
