Description

Technical Field

[0001] This utility model relates to the field of industrial Internet of Things (IoT) communication equipment technology, and specifically to a multifunctional industrial IoT gateway. Background Technology

[0002] Industrial IoT gateways, as core node devices in industrial IoT systems, primarily undertake data acquisition, protocol conversion, and network transmission functions for sensors, actuators, controllers, and other devices in the industrial field. They serve as crucial hubs connecting underlying industrial equipment with upper-level information management systems. Their performance directly impacts the stability, scalability, and data transmission reliability of the industrial IoT system.

[0003] In existing technologies, traditional industrial IoT gateways generally have the following shortcomings: First, the communication interface type is fixed, making it difficult to adapt to the device access requirements of various industrial communication protocols such as RS485, CAN bus, and Ethernet, thus limiting scalability; Second, the heat dissipation design mostly adopts a single heat sink or a simple air duct structure, which leads to the accumulation of internal heat during high-load operation, easily causing electronic components to age or fail. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional industrial IoT gateway that solves the problems of insufficient interface expandability and low heat dissipation efficiency in the prior art through modular interface design and split heat dissipation structure design, thereby improving the overall performance of the industrial IoT gateway.

The front of the main housing is provided with a modular interface compartment, which contains a sliding interface module tray. The interface module tray integrates at least two replaceable industrial communication interface units, including any combination of RS485 units, CAN bus units, and Ethernet units. The bottom of the main housing is provided with a split heat dissipation base, which contains a serpentine heat dissipation copper pipe. The serpentine heat dissipation copper pipe at the top of the heat dissipation base is tightly attached to the control motherboard and the power module by a thermally conductive silicone pad.

[0006] As a preferred technical solution of this utility model, the interface module tray is provided with guide rail grooves on both sides, and the inner wall of the modular interface compartment is provided with corresponding metal guide rails, and the guide rail grooves and metal guide rails achieve sliding fit.

The side wall of the modular interface compartment is provided with a lock hole that matches the positioning pin.

[0008] As a preferred technical solution of this utility model, the fastening point between the main housing and the heat dissipation base forms a stepped sealing edge, and an annular sealing groove is provided on the mating surface of the stepped sealing edge, with a rubber sealing ring embedded in the annular sealing groove.

[0009] As a preferred embodiment of this utility model, the bottom of the heat dissipation base is provided with a heat dissipation hole array, and the bottom of the heat dissipation hole array is covered with a removable dust filter.

[0010] As a preferred technical solution of this utility model, the top of the main housing is provided with a status indicator light bar, which is covered by a light-transmitting acrylic sheet. The light-transmitting acrylic sheet is sealed to the main housing by adhesive, and a waterproof sealing ring is connected to the inner side of the adhesive joint.

[0011] As a preferred technical solution of this utility model, the bottom four corners of the heat dissipation base are provided with anti-vibration pads, which are made of vulcanized rubber and have magnetic plates embedded inside.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1.

[0014] 2. High-efficiency heat dissipation performance: The split heat dissipation base combines serpentine heat dissipation copper pipes, heat dissipation hole arrays and thermal conductive silicone pads to form a multi-path heat conduction and air convection heat dissipation structure, which effectively reduces the internal temperature of the equipment during operation and extends the service life of electronic components.

[0015] 3. Multiple sealing protection: The stepped sealing edge, combined with the rubber sealing ring in the annular sealing groove and the waterproof sealing ring on the inside of the light-transmitting acrylic plate, significantly improves the overall waterproof and dustproof performance of the equipment, meeting the stringent requirements of industrial environments.

[0016] 4. Shock-absorbing and buffering protection: The vulcanized rubber shock-absorbing pads at the four corners of the bottom are embedded with magnetic strips. They can absorb vibration energy through the rubber material and enhance installation stability through magnetic fixation, effectively reducing the impact of industrial site vibration on internal components.

[0028] In this utility model, the top of the main housing 1 is provided with a status indicator light strip 19, which is covered by a light-transmitting acrylic sheet. The light-transmitting acrylic sheet is sealed to the main housing 1 by adhesive, and a waterproof sealing ring 20 is connected to the inner side of the adhesive joint.

[0029] In this utility model, the interface module tray 5 integrates at least two replaceable industrial communication interface units 6, which include any combination of RS485 unit, CAN bus unit, and Ethernet unit.

[0030] In this utility model, the bottom of the main housing 1 is provided with a split heat dissipation base 7. The heat dissipation base 7 is embedded with a serpentine heat dissipation copper pipe 8. The serpentine heat dissipation copper pipe 8 on the top of the heat dissipation base 7 is tightly attached to the control motherboard 2 and the power module 3 by a thermally conductive silicone pad 9. The bottom of the heat dissipation base 7 is provided with a heat dissipation hole array 17. The bottom of the heat dissipation hole array 17 is covered with a removable dust filter 18. The dust filter 18 is fixed to the bottom of the heat dissipation base 7 by magnetic attraction.

[0031] In this utility model, the bottom four corners of the heat dissipation base 7 are provided with anti-vibration pads 21. The anti-vibration pads 21 are made of vulcanized rubber and have magnetic plates 22 embedded inside.

[0032] As per the instruction manual Figure 4 As shown, the interface module tray 5 has guide rail grooves 10 on both sides, and the inner wall of the modular interface compartment 4 has a corresponding metal guide rail 11. The guide rail grooves 10 and the metal guide rail 11 are slidably engaged. The main housing 1 is located on one side of the interface module tray 5 and has an anti-detachment locking knob 12.
