[0050] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of this application will be further described below with reference to the accompanying drawings and through specific embodiments.

[0051] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0052] The intelligent gateway is the control center of the Internet of Things and a key component for the intelligence of local area networks. In the wave of the development of Industry 4.0, multiple devices are interconnected to form the Internet of Things, and the intelligent gateway is located between the perception layer and the network layer in the Internet of Things system. It is equivalent to the "brain" in the Internet of Things. While performing different types of network protocol conversions, it realizes functions such as information collection, information output, centralized control, remote control, and linkage control of various sensors, network devices, cameras, and hosts within the local area network.

[0053] The intelligent gateway is usually installed beside the network server and fixed in a wall-mounted manner. The existing wall-mounted structure of the intelligent gateway uses an integrated ear or a split ear. When installing, multiple screws are required for fastening, resulting in low disassembly and assembly efficiency and being unfavorable for quick installation and maintenance. Moreover, since the installation surface is on the front of the intelligent gateway, the surface is easily scratched when installing the screws, affecting the overall appearance.

[0054] To solve the above technical problems, as Figure 1 and Figure 2 shown, this embodiment provides an intelligent gateway 200 installed on a backplane 100. The backplane 100 is provided with a hanging structure and a limiting groove 102; the hanging structure and the limiting groove 102 are arranged opposite to each other. Exemplarily, the hanging structure is located at one end of the backplane 100 close to the top, and the limiting groove 102 is located at one end of the backplane 100 close to the bottom. In this way, when installing, first cooperate the intelligent gateway 200 with the hanging structure, hang one end of the intelligent gateway 200 on the backplane 100, and then cooperate the other end with the limiting groove 102 to fix the intelligent gateway 200.

[0055] As Figure 1 、 Figure 3 and Figure 4As shown, the smart gateway 200 includes a housing 1 and a locking assembly 2. The housing 1 has a hanging hole 1112 for connecting with a mounting structure. The locking assembly 2 includes a buckle 21 and a buckle lock 22. The first end of the buckle 21 is fixed to the housing 1, and the second end extends through the limiting groove 102. The buckle lock 22 is connected to the second end of the buckle 21, locking the buckle 21 to the back plate 100. During installation, simply hook the hanging hole 1112 of the housing 1 onto the mounting structure of the back plate 100, allowing the second end of the buckle 21 fixed to the housing 1 to pass through the limiting groove 102 of the back plate 100, and then connect the buckle lock 22 to lock the buckle 21, thus reliably fixing the smart gateway 200 to the back plate 100. During disassembly, after removing the buckle lock 22, tilt one end of the smart gateway 200 outward to detach it from the back plate 100. The smart gateway 200, together with the backplane 100, greatly reduces the installation and disassembly steps, significantly improving the convenience and efficiency of maintenance operations.

[0056] For example, continue to refer to Figure 2 The mounting structure is a hook 101, which is either integrally formed with the back panel 100 or a separate structure. For example, a panel is cut from the back panel 100 and bent into an L-shaped hook separate from the back panel 100. During installation, the hanging holes 1112 on the housing 1 are attached to the hook 101. Alternatively, the hook 101 can be welded or snap-fitted onto the back panel 100. To ensure the stability of the smart gateway 200 after mounting, two hooks 1112 and two hooks 101 are provided, one for each. Each of the limiting groove 102 and the locking component 2 is provided. After one end of the smart gateway 200 is hung on the back plate 100 by two hooks 101, the buckle 21 of the other end of the smart gateway 200 is pushed into the limiting groove 102. The first end of the buckle 21 is fixedly connected to the housing 1 in a detachable or non-detachable manner, and the second end is set to a structure that is adapted to the limiting groove 102, so that the buckle 21 is engaged with the limiting groove 102.

[0057] The limiting groove 102 is configured as a T-shaped groove, with the center line of the T-shaped groove coinciding with the center lines of the two hooks 101. Correspondingly, the second end of the buckle 21 is configured as a T-shaped structure, which is pushed into the T-shaped groove, allowing the smart gateway 200 to snap onto the back panel 100. Of course, the limiting groove 102 can also be configured as an I-shaped groove, with the second end of the buckle 21 configured as an I-shaped structure accordingly.

[0058] To further ensure the reliability of the smart gateway 200, a latch lock 22 is connected to the second end of the latch 21 to lock the smart gateway 200 onto the back panel 100.

[0059] In one embodiment, such as Figures 3-8As shown, the buckle 21 is configured to be detachably connected to the housing 1. During installation, the first end of the buckle 21 is first fixed to the housing 1, and then the second end of the buckle 21 is passed through the limiting groove 102 and engaged with the back plate 100.

[0060] In one embodiment, the first end of the latch 21 is fixed to the housing 1 by at least one fastening screw 23. The first end of the latch 21 is provided with a limiting step 211, which cooperates with the housing 1 to limit the movement. During installation, the smart gateway provided in this embodiment is first positioned with the housing 1 by the limiting step 211, and then the latch 21 is fixed to the housing by a fastening screw 23. During disassembly and assembly, only one fastening screw 23 needs to be loosened, which greatly reduces the disassembly and assembly time and improves the efficiency.

[0061] Of course, in other embodiments, the limiting step 211 may be omitted, and the buckle 21 may be directly fixed to the housing 1 by the fastening screws 23. To ensure the stability of the buckle 21, it may also be fixed with two fastening screws 23. Even so, compared with the installation structure of four or sixteen screws in the prior art, it saves disassembly and assembly time. Alternatively, the limiting step 211 may be used to position the buckle 21 to the housing 1 first, and then the buckle 21 may be fixed to the housing 1 by means of snap-fit ​​or other methods.

[0062] For example, the housing 1 is provided with a snap-fit ​​groove 1111. When the buckle 21 is fixedly connected to the housing 1, the buckle 21 is first pushed into the snap-fit ​​groove 1111 until the limiting step 211 on the buckle 21 abuts against one side of the snap-fit ​​groove 1111, and the buckle 21 is installed in place. The side of the buckle 21 with the limiting step 211 is provided with a first threaded hole 213, and the side wall of the housing 1 is provided with a first connecting hole 141. The fastening screw 23 passes through the first connecting hole 141 and screws into the first threaded hole 213 to firmly fix the buckle 21 to the housing 1. Then, after the hanging hole 1112 is engaged with the hook 101, the second end of the buckle 21 is passed through the limiting groove 102 and fixed by the buckle lock 22. During disassembly, first remove the latch lock 22, then loosen the fastening screw 23, tilt the smart gateway 200 away from the back panel 100, so that the second end of the latch 21 is disengaged from the limiting groove 102 or the smart gateway 200 is disengaged from the latch 21, and the smart gateway 200 can be removed from the back panel 100.

[0063] Furthermore, the first connecting hole 141 is located on the bottom wall of the housing 1. When the fastening screw 23 fixes the buckle 21, it passes through the first connecting hole 141 from the bottom wall of the housing 1 and is screwed into the first threaded hole 213, without affecting the appearance of the smart gateway 200.

[0064] The installation structure of the smart gateway 200 provided in this embodiment requires only one fastening screw 23 to fix the entire device; at the same time, the fastening screw 23 is located on the bottom wall of the housing 1 and is completely invisible from the appearance of the smart gateway 200 after installation, which not only improves the overall aesthetics of the product, but also effectively avoids the risk of scratching the appearance of the smart gateway 200 caused by the fastening screw 23.

[0065] In one embodiment, the second end of the latch 21 is provided with a locking groove 212, and the latch lock 22 passes through the locking groove 212 and abuts against the side wall of the back plate 100 away from the housing 1. After the latch lock 22 is inserted into the locking groove 212, it abuts against the side wall of the back plate 100 away from the housing 1, so that the latch 21 cannot be disengaged from the back plate 100, thereby fixing the smart gateway 200 to the back plate 100 by means of the latch 21.

[0066] For example, the locking groove 212 is configured as an inverted U-shaped groove, and the latch lock 22 includes a connecting beam and two locking legs located on both sides of the connecting beam. After the two locking legs are inserted into the U-shaped groove, their protruding portions abut against the side wall of the back plate 100 opposite to the housing 1, and the connecting beam abuts against the bottom of the inverted U-shaped groove. Thus, during disassembly, by lifting the latch lock 22 upwards and removing it from the locking groove 212, the latch 21 can be unlocked. Of course, in other embodiments, the locking groove 212 can also be configured as a hook-shaped groove, and correspondingly, the latch lock 22 is configured as an L-shaped pin structure.

[0067] The smart gateway 200 provided in this embodiment simplifies the disassembly and assembly steps and improves the efficiency of disassembly and assembly by adopting a top-mounted connection and bottom-locking mechanism 21; it also improves the convenience and efficiency of maintenance operations for the smart gateway 200.

[0068] like Figure 9 As shown, the smart gateway 200 also includes a PCB assembly 3 housed in the housing 1. The PCB assembly 3 is the core carrier of the smart gateway 200 hardware system and undertakes key tasks such as electrical connection, signal processing, protocol conversion, data exchange and system control.

[0069] In the existing technology, the smart gateway uses a U-shaped base plate and a top heat sink. During assembly, the PCB assembly 3 needs to be inserted and fixed in a direction parallel to the opening end of the U-shaped base plate. If there are terminals on the side of the PCB assembly 3 near the bottom of the U-shaped base plate, it will interfere with the bottom of the U-shaped base plate, limiting the expansion of the smart gateway's functions. Moreover, during installation, the PCB assembly 3 is prone to interference with the two sides of the U-shaped base plate.

[0070] In one embodiment, such as Figures 9-14As shown, the side wall of the housing 1 is provided with a terminal clearance opening 17 for the terminals of the PCB assembly 3 to pass through. The terminal clearance opening 17 for the terminals of the PCB assembly 3 to pass through can be provided on any of the four side walls of the housing 1, which can adapt to the wiring requirements of the terminals of the PCB assembly 3 on different side walls, eliminate the limitation of the terminal position on the structural design of the housing 1, and allow engineers to freely plan the PCB layout according to circuit optimization or heat dissipation requirements.

[0071] In one embodiment, the housing 1 includes a bottom shell 11, a top shell 12, and a first cover plate 13 and a second cover plate 14 connected to opposite sides of the top shell 12 and the bottom shell 11. The bottom shell 11 includes a bottom plate 111 and a first side plate 112 connected to one end of the bottom plate 111. The top shell 12 includes a top plate 121 and a second side plate 122 connected to one end of the top plate 121. The second side plate 122 is disposed opposite to the first side plate 112. The separate design of the bottom shell 11 and the top shell 12, combined with the sealing connection of the first cover plate 13 and the second cover plate 14 on both sides, allows the PCB assembly 3 to be directly placed into the bottom shell 11 from top to bottom, facilitating the assembly and fixation of the PCB assembly 3. The first side plate 112 and the second side plate 122 are disposed opposite to each other to form a reference alignment surface, eliminating accumulated assembly errors and ensuring the flatness of the seams after the housing 1 is assembled. During disassembly and maintenance, only the top shell 12 needs to be removed to expose the internal PCB assembly 3, without the need to disassemble the entire housing 1, significantly reducing maintenance time and the risk of component damage.

[0072] For example, the bottom plate 111 is inclined upward at one end near the first side plate 112 and at one end near the second side plate 122, so that its inner wall forms a positioning surface for positioning the two ends of the first cover plate 13 and the second cover plate 14, providing positioning for the installation of the first cover plate 13 and the second cover plate 14.

[0073] In one embodiment, a positioning strip 1121 is provided at the end of the first side plate 112 away from the bottom plate 111, and the positioning strip 1121 is flush with the end face of the first side plate 112. The inner wall of the top plate 121 is provided with a positioning groove 1213 that engages with the positioning strip 1121. The design of the positioning strip 1121 being flush with the end face ensures that when the top shell 12 is pressed down, the positioning groove 1213 automatically slides into the positioning strip 1121 until the end face is completely fitted, eliminating longitudinal misalignment and angular deviation between the top shell 12 and the bottom shell 11. The plug-in structure enables blind operation and quick alignment, and the shell 1 can be locked with a single pressing action. In addition, the design of the positioning strip 1121 being flush with the end face allows the positioning strip 1121 to be integrally formed with the first side plate 112, avoiding secondary processing and reducing burr removal costs.

[0074] Of course, in other embodiments, a positioning strip 1121 can also be provided at the end of the second side plate 122 away from the top plate 121, and a positioning groove 1213 that cooperates with the positioning strip 1121 can be provided on the inner wall of the bottom plate 111, which can also achieve the positioning of the top shell 12.

[0075] In one embodiment, a connecting plate 15 is provided on the side of the first cover plate 13 and the second cover plate 14 near the top plate 121. The connecting plate 15 is flush with the end faces of the first cover plate 13 and the second cover plate 14, so that the top plate 121 automatically and completely fits the connecting plate 15 when pressed down, eliminating assembly gaps and ensuring the lateral sealing of the housing 1. The top plate 121 and the connecting plate 15 are fixedly connected by a first fastener. The top plate 121 only needs to be fixed to the connecting plate 15 from above by the first fastener, eliminating the need for multi-angle screw tightening operations and improving assembly efficiency.

[0076] For example, each end of the two connecting plates 15 is provided with a second threaded hole 151, and the top plate 121 is provided with four corresponding second connecting holes 1211. The first fastener is a first screw, which passes through the second connecting hole 1211 and is screwed into the second threaded hole 151. The ends of the first cover plate 13 and the second cover plate 14 away from the connecting plates 15 are both connected to the bottom plate 111 by a third fastener. The first cover plate 13 and the second cover plate 14 are provided with connecting lugs 16, which are provided with fourth connecting holes 161. The bottom plate 111 is provided with a fourth threaded hole 1113. The third fastener is a third screw, which passes through the fourth connecting hole 161 and is screwed into the fourth threaded hole 1113.

[0077] Furthermore, a gap is left between the positioning strip 1121 and both ends of the first side plate 112, and correspondingly, a gap is also left between the positioning groove 1213 and both ends of the top plate 121, providing clearance space for the installation of the first cover plate 13 and the second cover plate 14.

[0078] In this embodiment, the snap-fit ​​groove 1111 is located at one end of the base plate 111 near the second cover plate 14, and one end of the snap-fit ​​groove 1111 is through-hole. The first connecting hole 141 is located on the second cover plate 14. After the limiting step 211 of the buckle 21 abuts against the end face of the second cover plate 14, the buckle 21 is pushed into place, and a fastening screw 23 can be screwed through the first connecting hole 141 and into the first threaded hole 213.

[0079] In one embodiment, a support platform 1114 is provided on the base plate 111, and the support surface of the support platform 1114 is parallel to the base plate 111. The PCB assembly 3 is fixed to the support surface of the support platform 1114 by a second fastener. Both ends of the PCB assembly 3 naturally fall to the support surface parallel to the base plate 111, automatically achieving horizontal alignment, eliminating the manual leveling process, and improving assembly efficiency. In addition, the support platform 1114 lifts the PCB assembly 3, forming a convection airflow channel between the PCB assembly 3 and the base plate 111, accelerating heat dissipation; at the same time, it isolates the metal interference of the base plate 111, improving the radio frequency signal-to-noise ratio.

[0080] For example, a support platform 1114 is provided at each of the four corners of the base plate 111, and each support platform 1114 is provided with a third threaded hole 1115. A third connection hole 311 is provided at each of the four corners of the PCB assembly 3. The second fastener is a second screw, which passes through the third connection hole 311 and is screwed into the third threaded hole 1115.

[0081] In one embodiment, a heat dissipation structure 1212 is provided on the top plate 121. By providing the heat dissipation structure 1212 on the top plate 121, the heat generated by the PCB assembly 3 is dissipated.

[0082] For example, the heat dissipation structure 1212 is a structure such as heat dissipation fins or heat dissipation holes.

[0083] The assembly method of the smart gateway 200 provided in this embodiment is as follows: Place the PCB assembly 3 from top to bottom and let it fall naturally onto the support platform 1114. Then move it horizontally towards the first side plate 112 so that the third connecting hole 311 on the PCB assembly 3 is aligned with the third threaded hole 1115 on the support platform 1114. Then, screw the second screw through the third connecting hole 311 and the third threaded hole 1115. After all four second screws are installed, align the positioning groove 1213 of the top shell 12 with the positioning strip 1121 and press it down so that the top shell 12 covers the bottom shell 11. Then, connect the first cover plate 13 and the second cover plate 14 to the two sides of the first side plate 112 and the second side plate 122 respectively. Finally, screw the first screw through the second connecting hole 1211 and the second threaded hole 151. After all four first screws are tightened, the smart gateway 200 is assembled.

[0084] In one embodiment, such as Figures 14-16 As shown, the PCB assembly 3 includes a PCB board 31, a signal light 32 integrated on the PCB board 31, and a light guide 33 located above the signal light 32. A display window 131 is provided on the side wall of the housing 1, and the light guide 33 transmits the light from the signal light 32 to the display window 131. Integrating the signal light 32 onto the PCB board 31 eliminates the need for wiring harnesses, resulting in a simpler structure and better connection reliability. The light guide 33 converts the point light source of the signal light 32 into uniform surface light from the display window 131, improving visibility in bright light environments.

[0085] In one embodiment, the light guide 33 includes a light guide base 331 and a light guide post 332. The light guide base 331 is provided with a light guide groove 3311 for accommodating the signal lamp 32. The light guide post 332 extends from the light guide base 331 to the display window 131. The light guide groove 3311 tightly wraps around the signal lamp 32, achieving a light capture rate of over 98%. The light guide post 332 can be bent and extended directly to the display window 131, with the optical path error controlled within ±3°.

[0086] For example, the number of light guide grooves 3311 and light guide pillars 332 is set according to the number of signal lights 32, so that the signal lights 32, light guide grooves 3311 and light guide pillars 332 are set in a one-to-one correspondence.

[0087] In one embodiment, the bottom of the light guide base 331 is provided with a snap-fit ​​part 3312 for snapping and fixing with the PCB board 31. The PCB board 31 is provided with snap-fit ​​holes, and the snap-fit ​​part 3312 is configured as a claw. The claw engages with the snap-fit ​​hole to achieve snap-fit ​​fixing of the light guide 33 to the PCB board 31. Of course, the snap-fit ​​part 3312 can also be configured as a snap-fit ​​boss or other structures.

[0088] For example, three claws are provided, and the three claws are evenly distributed at the bottom of the light guide base 331 to achieve a stable connection of the light guide 33.

[0089] In one embodiment, the top wall of the snap-fit ​​part 3312, the light guide groove 3311, and the side of the light guide post 332 are all provided with a light-shielding layer. The light-shielding layer effectively blocks the stray light of the signal light 32, ensuring that its light is precisely constrained and guided to the light guide post 332, and finally realizes that the light route is efficiently converted from the vertical incident direction to the horizontal emission direction, and is clearly displayed in the display window 131 of the housing 1.

[0090] For example, the light-blocking layer is formed by coating with black or other dark-colored light-blocking ink.

[0091] The smart gateway 200 provided in this embodiment achieves initial positioning through the cooperation of the mounting holes 1112 of the housing 1 and the mounting structure of the back plate 100, and is finally fixed using the locking assembly 2; this improves the efficiency of disassembly and assembly, thereby enhancing the convenience and efficiency of maintenance operations. By designing the structure and assembly of the housing 1, a terminal clearance port 17 for the terminals of the PCB assembly 3 to pass through can be provided on any of the four side walls of the housing 1, perfectly adapting to the wiring requirements of the PCB assembly 3 terminals on different side walls, improving the flexibility and adaptability of product assembly. By improving the structure of the PCB assembly 3, the indicator light 32 is directly integrated into the PCB board 31, and the light is conducted through the optimized light guide 33, simplifying the product structure and improving installation efficiency and operational reliability.

For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of this application. The content of this specification should not be construed as a limitation of this application.
