Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a filter cavity with a buffer structure. Background Technology

[0002] A filter is a key device used in signal processing. By selectively allowing or blocking signals within a specific frequency range, it achieves signal filtering, separation, and purification. Filters are widely used in communications, electronic equipment, power systems, and other fields. According to their function, filters can be divided into low-pass, high-pass, band-pass, and band-stop filters. Low-pass filters allow low-frequency signals to pass through while suppressing high-frequency signals, while high-pass filters do the opposite. Band-pass filters only allow signals in a specific frequency band to pass through, and band-stop filters block signals in a specific frequency band. The filter cavity is the key carrier for signal filtering, but existing filter cavities have certain defects.

[0003] A cavity filter, as described in application number CN202021054307.7, includes a metal cavity and a resonant rod. The metal cavity includes a bottom wall, side walls, and a cavity formed between the bottom wall and the side walls. The resonant rod is welded to the bottom wall. The resonant rod is firmly welded, the structure is simple, and the installation is convenient, which is conducive to automated installation design. It does not use screws for installation, resulting in low material costs and reduced production costs. However, this filter cavity cannot effectively protect internal components when subjected to vibration or external impact, easily leading to component damage or performance degradation. Furthermore, the cavity's heat dissipation structure is unreasonable, preventing timely heat dissipation and causing internal component temperatures to rise, affecting their service life and performance. Additionally, it cannot organize the messy internal component cables, potentially impacting the equipment.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a filter cavity with a buffer structure. Utility Model Content

[0005] The purpose of this utility model is to provide a filter cavity with a buffer structure to solve the problems mentioned in the background art, which are that when subjected to vibration or external impact, the internal components cannot be effectively protected, which can easily lead to component damage or performance degradation. In addition, the cavity heat dissipation structure is unreasonable, and heat cannot be dissipated in time, which can cause the internal component temperature to rise, affecting its service life and performance. Furthermore, it is impossible to organize the messy internal component cables, which may affect the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter cavity with a buffer structure, comprising a cavity shell and a shielding and storage mechanism. The shielding and storage mechanism is fixedly connected to the inner wall of the cavity shell, and the shielding and storage mechanism includes an inner metal mesh fixedly connected to the inner wall of the cavity shell. A conductive connecting strip is fixedly connected to one side of the inner metal mesh, and an outer metal mesh is fixedly connected to one side of the conductive connecting strip. A magnetic layer is fixedly connected to one side of the outer metal mesh, and a magnetic block is adsorbed on one side of the magnetic layer. A storage rack is provided inside the magnetic block.

[0007] Preferably, the cavity shell is internally fixedly connected with reinforcing ribs, and the bottom of the inner surface of the cavity shell is fixedly connected with a composite buffer mechanism.

[0008] Preferably, the composite buffer mechanism includes a buffer bracket fixedly connected to the bottom of the inner surface of the cavity shell, and a rubber buffer damper fixedly connected to the top of the buffer bracket. A buffer spring is sleeved on the outer surface of the rubber buffer damper, and a mounting plate is fixedly connected to the top of the rubber buffer damper.

[0009] Preferably, the inner surface of the top of the cavity shell is fitted with sealant, and a groove is formed on the inner surface of the top of the cavity shell.

[0010] Preferably, a fastening bolt is connected through the inner surface of the slot, and a sealing groove is provided on one side of the slot.

[0011] Preferably, the top of the sealant is fixedly connected to a device cover, and the outer surface of the device cover is fixedly connected to a heat dissipation channel.

[0012] Preferably, the outer surface of the heat dissipation channel is fixedly connected with heat dissipation fins, and the bottom of the equipment cover is fixedly connected with a U-shaped buckle, the inside of which is provided with a reinforcing pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a shielded storage mechanism, ensures the stable operation of the filter cavity, playing a dual protection and intelligent storage role, effectively improving the performance and reliability of the equipment, preventing interference signals from entering the cavity, ensuring that the filtered signal is not contaminated by noise, and greatly improving the accuracy and purity of the output signal. Through the adjustable storage method, it can not only avoid signal loss caused by cable tangling, but also prevent cable displacement and wear caused by vibration. At the same time, it can also optimize the internal space layout of the cavity, leaving sufficient space for component heat dissipation and maintenance, significantly enhancing the practicality and durability of the filter cavity;

[0015] 2. This utility model, through the combination of a composite buffer mechanism and reinforcing ribs, collaboratively constructs a three-dimensional protection system for the cavity shell, effectively preventing internal components from malfunctioning due to severe vibrations, such as loose solder joints and broken circuits. The reinforcing ribs are cleverly distributed inside the sides of the cavity shell to further enhance the buffering effect. When the impact force is transmitted to the cavity shell, the reinforcing ribs, with their rigid structure, evenly distribute the external force to the entire cavity surface, avoiding local stress concentration that could lead to shell deformation. Both work from the dual dimensions of energy absorption and structural reinforcement to comprehensively ensure the structural integrity and operational stability of the filter under complex vibration environments.

[0021] 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.

[0022] like Figures 1-2As shown, a filter cavity with a buffer structure includes a cavity shell 1 and a shielding and storage mechanism 2. The shielding and storage mechanism 2 is characterized in that the inner wall of the cavity shell 1 is fixedly connected to the shielding and storage mechanism 2, and the shielding and storage mechanism 2 includes an inner metal mesh 201 fixedly connected to the inner wall of the cavity shell 1. A conductive connecting strip 202 is fixedly connected to one side of the inner metal mesh 201, and an outer metal mesh 203 is fixedly connected to one side of the conductive connecting strip 202. A magnetic layer 204 is fixedly connected to one side of the outer metal mesh 203, and a magnetic block 205 is adsorbed onto one side of the magnetic layer 204. The magnetic block 205 has a storage rack 206 inside. The conductive connecting strip 202 connects the inner metal mesh 201 and the outer metal mesh 203 together. The inner metal mesh 201 is close to the inner wall of the cavity shell 1. Both the inner metal mesh 201 and the outer metal mesh 203 are made of materials with good conductivity to reduce external electromagnetic interference and ensure the accuracy of the filtered signal. The magnetic block 205 can change its position on the magnetic layer 204 according to the internal components of the cavity shell 1, thereby organizing the cables of the internal components.

[0023] like Figure 3 As shown, a reinforcing rib 3 is fixedly connected inside the cavity shell 1, and a composite buffer mechanism 4 is fixedly connected to the bottom of the inner surface of the cavity shell 1. The composite buffer mechanism 4 includes a buffer bracket 401 fixedly connected to the bottom of the inner surface of the cavity shell 1, and a rubber buffer damper 402 is fixedly connected to the top of the buffer bracket 401. A buffer spring 403 is sleeved on the outer surface of the rubber buffer damper 402, and a mounting plate 404 is fixedly connected to the top of the rubber buffer damper 402. The buffer brackets 401 are distributed in an alternating pattern at the bottom of the inner surface of the cavity shell 1, which effectively improves the strength of the bottom of the inner surface of the cavity shell 1. When the cavity shell 1 is subjected to vibration or external impact, the rubber buffer damper 402 first undergoes elastic deformation to absorb part of the impact force. Then, the buffer spring 403 further buffers and consumes energy through its own elasticity and damping characteristics, reducing the impact force on the internal components at the top of the mounting plate 404.

[0024] Furthermore, a sealant 5 is attached to the inner top surface of the cavity shell 1, and a groove 6 is provided on the inner top surface of the cavity shell 1. A fastening bolt 7 is connected through the inner surface of the groove 6, and a sealing groove 8 is provided on one side of the groove 6. The U-shaped buckle 12 on the equipment cover 9 fits into the groove 6 of the cavity shell 1. After the U-shaped buckle 12 is inserted, the fastening bolt 7 is tightened. The equipment cover 9 and the cavity shell 1 are tightly pulled together through the thread drive. The sealant 5 is embedded in the sealing groove 8, and the pressure deformation fills the gap, blocking the infiltration of gas and liquid, and ensuring that the cavity shell 1 is sealed and installed stably.

[0025] Furthermore, the top of the sealant 5 is fixedly connected to the equipment cover 9, and the outer surface of the equipment cover 9 is fixedly connected to the heat dissipation channel 10. The outer surface of the heat dissipation channel 10 is fixedly connected to the heat dissipation fins 11, and the bottom of the equipment cover 9 is fixedly connected to the U-shaped buckle 12. The U-shaped buckle 12 is provided with a reinforcing gasket 13. The dense heat dissipation holes in the heat dissipation channel 10 increase the air circulation area, and the heat dissipation fins 11 expand the heat dissipation contact range. The two work together to accelerate heat exchange. The reinforcing gasket 13 increases the friction, making the connection between the U-shaped buckle 12 and the fastening bolt 7 more secure and preventing the U-shaped buckle 12 from loosening.

[0026] Working principle: When using the filter cavity with buffer structure, firstly, according to the position of the components on the surface of the mounting plate 404, the magnetic block 205 is attracted to a suitable position on the magnetic layer 204. The component cables are then stored using the storage rack 206 to prevent tangling during use. Next, the U-shaped buckle 12 on the device cover 9 is aligned with the slot 6 on the cavity shell 1, and pressure is applied to engage the U-shaped buckle 12. Then, the fastening bolt 7 is tightened to quickly connect the device cover 9 to the cavity shell 1. The sealant 5 is then embedded into the sealing groove 8. Then, when the filter is working... The heat generated inside is conducted to the heat dissipation channel 10 through the equipment cover 9, and the heat is quickly carried away by the heat dissipation fins 11. At the same time, the inner metal mesh 201 and the outer metal mesh 203 of the shielding and storage mechanism 2 are connected by the conductive connecting strip 202 to form a shielding layer to reduce electromagnetic interference. Finally, the reinforcing rib 3 and the composite buffer mechanism 4 ensure the stability of the cavity structure. The rubber buffer damper 402 and the buffer spring 403 of the composite buffer mechanism 4 cooperate with the mounting plate 404 through the buffer bracket 401 to absorb external vibration and impact. This is the working principle of the filter cavity with buffer structure.
