TECHNICAL FIELD
[0001] The present application relates to the technical field of exchange equipment of computer hardware modules, and in particular to an exchange equipment based on an LRM architecture. BACKGROUND
[0002] In the design of communication exchange equipment, a common solution includes adopting a standard rack structure, connecting various functional modules such as computing modules, service modules, AI intelligent computing modules, and data storage modules through a backboard, and these modules usually exchange data with external devices through interfaces such as Ethernet ports, CAN interfaces, TSN management interfaces, and maintenance management interfaces.
[0003] However, the existing communication exchange equipment has certain deficiencies in terms of modular design, heat dissipation performance, and reliability. For example, the traditional rack structure is inconvenient to replace and maintain, as it requires the disassembly of a large number of screws, increasing maintenance time and cost. In addition, the efficiency of the heat dissipation system is low, which can easily lead to overheating of the equipment, affecting the long-term stable operation of the equipment. Furthermore, the existing locking mechanism may have the risk of loosening during installation, affecting the overall stability of the equipment. Therefore, how to design a more modular, easy-to-maintain, excellent heat dissipation performance, and stable communication exchange equipment has become a technical problem to be solved. CONTENT OF THE INVENTION
[0004] To overcome the deficiencies of the prior art, the present application provides an exchange equipment based on an LRM architecture, which adopts a modular design, is easy to maintain, has excellent heat dissipation performance, and can realize stable communication exchange.
[0005] The present application is implemented through the following technical solutions:
[0006] An exchange equipment based on an LRM architecture includes a rack and a plurality of unit frames containing computer hardware modules. The rack includes a top plate, a bottom plate, and side plates. The side plates are arranged parallel between the top plate and the bottom plate, forming a frame structure with a horizontal opening. The back of the rack is provided with a backboard frame, and the backboard frame is provided with an interconnection plate. The interconnection plate is integrated with a plurality of LRM connector interfaces for connecting with the computer hardware modules. The bottom plate is provided with a plurality of slot positions suitable for the unit frames. The bottom plate is provided with a base plate below, and a containing space is formed between the bottom plate and the base plate. The containing space is provided with a fan module, which includes a fan and a fan drive board. The fan drive board is connected to the backboard frame through the LRM connector interface.
[0007] By adopting the above technical scheme, the switching device based on the LRM architecture realizes quick plugging and safe locking of each computer hardware module through modular design, improves the flexibility and maintainability of the device. By setting the upper interconnection plate in the back plate frame and the LRM connector interface thereon, stable connection and efficient communication between the modules are ensured. At the same time, the design of the fan module effectively solves the problem of heat dissipation of the device. By connecting the fan driving plate to the back plate frame, intelligent monitoring and speed regulation of the fan are realized, and the heat dissipation efficiency and reliability of the device are improved. In addition, the structural design of the rack has good electromagnetic compatibility and protection performance, ensuring the stable operation of the device in complex environments.
[0008] Optionally, the unit frame is provided with a quick pull mechanism for extraction.
[0009] By adopting the above technical scheme, the quick pull mechanism allows the unit frame to be quickly pulled out, facilitating maintenance and replacement, and improving the maintainability and flexibility of the device. Specifically, the quick pull mechanism includes a lever, the middle segment of the lever is provided with a hinge seat for hinging at the bottom of the unit frame, the upper segment is provided with a handle portion, and the lower segment is provided with a support portion abutting against the bottom plate. This design not only simplifies the installation and disassembly process of the unit frame, but also ensures the stability of the unit frame during installation, effectively improving the overall reliability of the device.
[0010] Further optionally, the quick pull mechanism includes a lever, the middle segment of the lever is provided with a hinge portion for hinging at the bottom of the unit frame, the upper segment is provided with a handle portion, and the lower segment is provided with a support portion abutting against the bottom plate.
[0011] By adopting the above technical scheme, the design of the quick pull mechanism makes the installation and disassembly of the unit frame more convenient, improving the maintenance efficiency of the device. Specifically, the middle segment of the lever is hinged to the bottom of the unit frame through the hinge seat, the handle portion of the upper segment is convenient for manual operation by the operator, and the support portion of the lower segment abuts against the bottom plate, ensuring the stability and safety of the unit frame during extraction. When the unit frame needs to be extracted, since the support portion abuts against the bottom plate, a rotating fulcrum is formed, and only the handle portion needs to be pulled outwards. The hinge seat will drive the unit frame to move outward, so that the unit frame panel protrudes from the rack, making it convenient for the operator to take out the unit frame. This design not only simplifies the maintenance process, but also reduces the risk of device damage caused by frequent disassembly, improving the overall reliability and service life of the device.
[0012] Optionally, a locking mechanism is provided between the rack and the unit frame.
[0013] By adopting the above technical scheme, the locking mechanism can effectively improve the connection stability between the rack and the unit frame, ensuring the reliable operation of the device in harsh environments. This design not only improves the overall structural strength of the device, but also facilitates quick installation and disassembly of the modules, improving the maintenance convenience of the device.
[0014] Further optionally, the locking mechanism includes a stud, a C-shaped buckle, an elastic member, and a pressing pad; the stud penetrates the elastic member, the pressing pad, and the C-shaped buckle in sequence and is threadedly connected in a threaded hole provided on the bottom plate, and the C-shaped buckle is clamped on the rack and the unit frame by the elastic member providing a pre-tightening force.
[0015] By adopting the above technical solution, the design of the locking mechanism enables the unit frames to be stably fixed in the rack, improving the overall structural strength and reliability of the equipment. Specifically, the combination design of the stud, the C-shaped buckle, the elastic member, and the pressing pad not only effectively fixes the unit frames but also ensures that the C-shaped buckle is firmly clamped on the rack and the unit frame through the pre-tightening force provided by the elastic member, thereby avoiding loosening caused by vibration or impact. This design is particularly suitable for military and industrial application scenarios, improving the stability and service life of the equipment.
[0016] Optionally, the clamping edge of the C-shaped buckle is in a wedge structure; the rack and the unit frames are provided with clamping grooves adapted to the C-shaped buckle.
[0017] By adopting the above technical solution, the clamping edge of the C-shaped buckle is in a wedge structure, which can more easily enter the clamping grooves on the rack and the unit frame during installation, improving installation efficiency and convenience. At the same time, the wedge structure design enables the C-shaped buckle to tightly fit the clamping grooves on the rack and the unit frame and gradually generate a pre-tightening force during installation, further enhancing the reliability of the C-shaped buckle and ensuring that the modules maintain a good connection state during long-term operation. The adapted clamping groove design also improves the assembly precision of the entire equipment, reduces the failure rate caused by improper assembly, and improves the overall reliability and safety of the equipment.
[0018] Optionally, an elastic pad is provided between the bottom plate and the backing plate.
[0019] By adopting the above technical solution, the elastic pad can effectively reduce mechanical impact caused by vibration during transportation and installation of the equipment, improving the stability and reliability of the equipment and prolonging the service life.
[0020] Optionally, the side plate is in a hollow structure; the bottom plate and the top plate are provided with ventilation holes.
[0021] By adopting the above technical solution, the hollow side plate and the ventilation holes provided on the bottom plate and the top plate significantly enhance the heat dissipation performance of the equipment, effectively reducing internal heat accumulation and improving the stability and reliability of the equipment. At the same time, good ventilation design also helps to prolong the service life of the equipment and reduce the failure rate caused by overheating.
[0022] Optionally, the back plate frame is provided with positioning columns for limiting the position of the unit frame.
[0023] By adopting the technical scheme, the position of the unit frame can be accurately limited during installation and disassembly, correct docking and stable connection between modules are ensured, and the assembly efficiency and reliability of the equipment are improved.
[0024] Optionally, the two sides of the slot are provided with a pad strip.
[0025] By adopting the technical scheme, the pad strip lifts the unit frame, and a ventilation gap is formed between the unit frame and the bottom plate, so that the ventilation performance is improved.
