Specific embodiments

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] As Figure 1 , Figure 2 shown, an external PCBA motherboard includes a housing 1 and a multi-layer circuit board body 2.

[0022] As Figure 2 , Figure 3 shown, a multi-layer slide rail 3 for the circuit board body 2 to slide and embed is horizontally arranged between the inner walls on both sides of the housing 1, and mounting holes 4 for the circuit board body 2 to be inserted are arranged at both ends of the housing 1, and the mounting holes 4 are arranged in a vertically staggered manner at both ends of the housing 1.

[0023] As Figure 2 , Figure 3 shown, a wiring board 5 embedded in the mounting hole 4 is arranged at the end of the circuit board body 2, and locking members 6 for fixing it in the mounting hole 4 are arranged at both ends of the wiring board 5. The locking member 6 includes a connecting plate 61, a locking plate 62, a locking block 63 and a handle 64.

[0024] As Figure 2 , Figure 3 shown, the connecting plate 61 is vertically arranged at the end of the wiring board 5, the locking plate 62 is fixed to the connecting plate 61 and is used to abut against the side wall of the mounting hole 4. The locking block 63 is arranged on the outer wall of the locking plate 62, and a locking groove 65 for the locking block 63 to be embedded is arranged on the side wall of the mounting hole 4. The handle 64 is arranged at the outer end of the locking plate 62 and is tilted outward.

[0025] As Figure 2 , Figure 3 shown, there is a gap between one end of the circuit board body 2 away from the wiring board 5 and the housing 1, and the multi-layer circuit board body 2 divides the interior of the housing 1 into a serpentine cooling channel 7. An air inlet 11 and an air outlet 12 communicating with both ends of the cooling channel 7 are respectively arranged on the side wall of the housing 1, and a fan 13 is arranged in the air inlet 11.

[0026] As Figure 2 , Figure 3 shown, serpentine water-cooling channels 8 are provided inside both sides of the outer shell 1, and a water inlet pipe 81 and a water outlet pipe 82 communicating with both ends of the water-cooling channel 8 are respectively provided on the outer shell 1.

[0027] When the entire external PCBA motherboard structure is installed and used, each layer of circuit board body is inserted into the installation hole 4, and the circuit board body 2 slides in the slide rail 3 to support the circuit board body 2. After the wiring board 5 on the circuit board is embedded into the installation hole 4, the locking block 63 on the locking plate 62 automatically embeds into the locking groove 65 on the side wall of the installation hole 4 to fix the entire circuit board body 2.

[0028] When maintenance and repair of the circuit board body 2 are required, the handle 64 can be pressed close to the wiring board 5 to cause the handle 64 to drive the locking plate 62 to bend and the locking block 63 to disengage from the locking groove 65, so that the wiring board 5 and the circuit board body can be pulled out, thereby enabling the repair of the circuit board body.

[0029] Therefore, by providing the outer shell 1 capable of carrying multiple layers of circuit board bodies 2 and cooperating with the pull-out type circuit board body 2, the pull-out type external installation of the circuit board body 2 is realized, and the entire structure is located entirely outside the electronic device. The repair process of the circuit board body 2 does not require the disassembly of the electronic device, reducing the time required for the repair process, lowering the high repair cost, and facilitating maintenance and repair.

[0030] Meanwhile, when the circuit board body 2 is working, since the layout of the circuit board body 2 is staggered and a serpentine cooling channel 7 is formed inside the outer shell 1, the cold air can be sent into the outer shell 1 in cooperation with the fan 13 and flow along the serpentine cooling channel 7, so that the cold air can flow through the front and back surfaces of each circuit board body 2 to fully cool down the circuit board body 2 and ensure the heat dissipation effect of the circuit board body 2.

[0031] At the same time, cold water can be introduced into the water inlet pipe 81 on the outer shell 1, and the used cold water is discharged outside along the water outlet pipe 82. The water-cooling channel 8 inside the outer shell 1 is used to cool down the inside of the outer shell 1, thereby further fully cooling down the circuit board body 2 and ensuring the heat dissipation effect of the circuit board body 2.

[0032] As Figure 2 , Figure 3 shown, the outer shell 1 includes a housing 14 and a cover plate 15. The cover plate 15 is arranged at the upper end of the housing 14. Hook 16 is provided at each of the four corner positions of the housing 14, and a hook hole 17 for the hook 16 to pass through is provided on the cover plate 15. Therefore, by providing the combined outer shell 1, the cover plate 15 can be opened to facilitate wiring of each layer of circuit board body 2 and also make the repair process easy and convenient.

[0033] As Figure 2 , Figure 3 shown, a wire threading hole 18 is provided at the bottom wall position of the housing 14, so that the trunk line can penetrate into the housing 14 from the bottom of the housing 14, realizing the concealed installation of the trunk line. A shock pad 19 surrounding the wire threading hole 18 is provided on the lower end face of the housing 14 to increase the seismic performance of the entire structure. A glue layer is provided on the lower end face of the shock pad 19 for realizing the quick installation and fixation of the entire structure.

[0034] The specific embodiments are only explanations of the present invention, and they are not limitations on the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
