[0033] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1-9 As shown, the structure of a field edge computing gateway in this embodiment includes a first housing 1, a circuit board assembly 2, and a second housing 3. The circuit board assembly 2 is disposed on the first housing 1, and the first housing 1 is provided with a plurality of positioning posts 1011. The circuit board assembly 2 is provided with a plurality of positioning holes 202, and each positioning post 1011 is inserted into a positioning hole 202. The second housing 3 includes an upper wall panel 301 and a front wall panel 302 disposed on the front side of the upper wall panel 301. The upper wall panel 301 abuts against the upper part of the first housing 1 and the two are detachably connected. The front wall panel 302 abuts against the front part of the first housing 1 and the two are detachably connected.

[0035] By designing the second housing 3 as an "L"-shaped structure, with the upper wall panel 301 and the front wall panel 302 perpendicular to each other, and both abutting against the first housing 1 from different directions, the upper wall panel 301 and the front wall panel 302 cooperate to allow the first housing 1 to serve as the assembly positioning surface for the second housing 3 in the vertical direction, and the front wall panel 302 cooperates with the first housing 1 to serve as the assembly positioning surface for the second housing 3 in the front-back direction. This ensures accurate relative positioning between the second housing 3 and the first housing 1. The positioning hole 202 extends vertically, and the positioning post 1011 forms a shaft-hole fit with the positioning hole 202, ensuring accurate relative positioning between the circuit board assembly 2 and the first housing 1. This improves assembly efficiency and optimizes the appearance of the assembled product. Furthermore, during installation, the circuit board assembly 2 is inserted into the first housing 1 from top to bottom, and the second housing 3 is matched with the first housing 1 from front to back and then detachably connected by bolts or other means, reducing assembly difficulty and time.

[0036] In this embodiment, the first housing 1 includes a lower wall panel 101, a left wall panel 102, a rear wall panel 103, and a right wall panel 104. The left wall panel 102, the rear wall panel 103, and the right wall panel 104 are arranged to form a U-shaped plate structure. The lower part of the U-shaped plate structure is connected to the lower wall panel 101. The first housing 1 and the second housing 3 are connected to form a square housing with an inner cavity. A plurality of positioning posts 1011 are all disposed on the lower wall panel 101.

[0037] The positioning post 1011 of the lower wall plate 101 can position the circuit board assembly 2, and the lower wall plate 101 itself can provide support for the circuit board assembly 2.

[0038] In this embodiment, the upper wall panel 301 includes an upper wall body 3011 and a U-shaped flange 3012 protruding downward from the upper wall body 3011. The lower surface of the upper wall body 3011 abuts against the upper surface of the U-shaped plate structure, and the surface of the U-shaped flange 3012 facing the outside of the inner cavity abuts against the surface of the U-shaped plate structure facing the inside of the inner cavity.

[0039] During the assembly process of the second housing 3 matching the first housing 1 from front to back, the U-shaped flange 3012 can form a sliding fit with the left and right sides, the left wall plate 102 and the right wall plate 104, and play the role of slide rail guide. At the same time, the fit between the U-shaped flange 3012 and the left wall plate 102 and the right wall plate 104 can also determine the relative position of the second housing 3 and the first housing 1 in the left-right direction. After the U-shaped flange 3012 abuts against the rear wall plate 103, the relative position of the second housing 3 and the first housing 1 in the front-back direction can be determined. And the lower surface of the upper wall body 3011 abuts against the upper surface of the U-shaped plate structure can determine the relative position of the second housing 3 and the first housing 1 in the vertical direction. That is, the first housing 1 and the upper wall plate 301 can achieve assembly positioning in multiple directions.

[0040] In this embodiment, the upper wall panel 301 further includes a rear positioning rib 3013 protruding rearward from the U-shaped flange 3012. The rear wall panel 103 is provided with a rear positioning groove 1031, and the rear positioning rib 3013 is conformally inserted into the rear positioning groove 1031. The conformal fit between the rear positioning rib 3013 and the rear positioning groove 1031 determines the relative positions of the upper wall panel 301 and the rear wall panel 103 in multiple directions, which can further ensure the accuracy of assembly positioning and the reliability of connection after assembly.

[0041] In this embodiment, the upper wall panel 301 further includes two rear connecting seats 3014 disposed on the U-shaped flange 3012. The upper part of the left and right sides of the rear wall panel 103 is respectively provided with a first through hole 1032. Two first bolts 5 are respectively passed through the first through holes 1032 and respectively connected to the rear connecting seats 3014 to realize the connection between the upper wall panel 301 and the rear wall panel 103, which can facilitate disassembly and assembly.

[0042] In this embodiment, the front part of the lower wall panel 101 is provided with an upwardly protruding front flange 1012, the left side of the front flange 1012 is provided with a left front connecting seat 10141013, and the right side of the front flange 1012 is provided with a right front connecting seat 1014.

[0043] The front wall panel 302 includes a front wall body 3021 and two flanges 3022 protruding rearward from the front wall body 3021. The two flanges 3022 are respectively disposed on the left and right sides of the front wall body 3021. The rear surfaces of the two flanges 3022 abut against the front surfaces of the left wall panel 102 and the right wall panel 104, respectively. The surfaces of the two flanges 3022 facing the interior of the cavity abut against the left surface of the left front connecting seat 10141013 and the right surface of the right front connecting seat 1014, respectively.

[0044] The left wall panel 102, right wall panel 104, front flange 1012, front wall body 3021, and two flanges 3022 together ensure that the relative position of the front wall panel 302 and the first housing 1 in the front-back direction and the left-right direction is accurate.

[0045] In this embodiment, a front positioning rib 1015 is provided in the middle of the front flange 1012, and a front positioning groove 3023 is provided on the front wall body 3021. The front positioning rib 1015 is inserted into the front positioning groove 3023 in a conformal manner. A second through hole 3024 is provided on the lower part of the left and right sides of the front wall body 3021, and two second bolts 6 are respectively passed through the second through holes 3024 and connected to the left front connecting seat 10141013 and the right front connecting seat 1014, respectively, to realize the connection between the front wall plate 302 and the lower wall plate 101.

[0046] The front positioning rib 1015 conformally fits the front positioning groove 3023, which determines the relative positions of the front wall panel 302 and the lower wall panel 101 in multiple directions, thereby further ensuring the accuracy of assembly positioning and the reliability of connection after assembly.

[0047] In this embodiment, the circuit board assembly 2 is provided with multiple configuration interfaces 201, and the front wall panel 302 and the right wall panel 104 are both provided with interface clearance holes; the upper wall panel 301 and the left wall panel 102 are both provided with heat dissipation holes. For example, the configuration interface 201 can be a 4G / 5G antenna interface, an RF antenna interface, a SIM card slot, a LAN 2.5G interface, a USB 2.0 interface, an HDMI 2.1 interface, etc. The configuration interfaces 201 are all existing technologies. This embodiment does not improve the power supply and communication principle of the circuit board assembly 2, therefore the power supply and communication principle of the circuit board assembly 2 will not be described in detail here.

[0048] In this embodiment, an external snap-fit ​​connector 4 is also included, which is connected to the rear side of the first housing 1 by a third bolt 7.

[0049] In this embodiment, the external snap-fit ​​connector 4 includes a connecting portion 401, a first elastic snap-fit ​​portion 402 disposed on the left side of the connecting portion 401, and a second elastic snap-fit ​​portion 403 disposed on the right side of the connecting portion 401. When installed in specific locations such as industrial sites, transportation hubs, and warehousing logistics facilities, by providing a matching connector for the external snap-fit ​​connector 4 on the equipment cabinet or wall, installation only requires inserting the matching connector into the slot of the external snap-fit ​​connector 4. The elasticity of the first elastic snap-fit ​​portion 402 and the second elastic snap-fit ​​portion 403 provides clamping force, thereby connecting the external snap-fit ​​connector 4 to the matching connector on the equipment cabinet or wall, thus improving installation efficiency.
