Description

Technical Field

[0001] This invention belongs to the field of GPU mounting technology, specifically a tool-free GPU mounting bracket structure. Background Technology

[0002] Servers possess high-speed CPU processing power, reliable operation over extended periods, robust I / O external data throughput, and superior scalability. Generally, depending on the services provided, servers are capable of responding to service requests, providing services, and ensuring service availability.

[0003] GPU (Graphics Processing Unit) frees up application graphics processing instructions from the main processor (CPU). This process frees up main processor resources for other tasks and executes application graphics processing instructions on hardware, meeting the current demands for higher-level, more detailed, and lifelike rendering, video processing, and visualization. Without a GPU, graphics instructions require software emulation, which consumes main processor resources, resulting in unacceptably low performance. GPUs reduce the graphics card's dependence on the CPU and perform some of the work that the CPU used to do, especially in 3D graphics processing. The core technologies used by GPUs include hardware T&L (geometry transformation and lighting processing), cubic environment mapping and vertex blending, texture compression and bump mapping, and dual-texture four-pixel 256-bit rendering engines. Hardware T&L technology can be considered a hallmark of GPUs.

[0004] The ever-increasing demands of servers for data storage and processing speed are driving performance improvements, requiring more and better-performing GPUs for acceleration. However, finding the best and simplest way to place GPUs in server chassis presents a significant challenge for designers.

[0005] The current mainstream method for installing GPUs in servers is to fix the GPU to a bracket with screws. The GPU plugs into a riser board, and then the bracket is screwed onto the chassis. The advantage of this method is that the screw-fixed structure has good strength and can effectively protect the GPU from damage during vibration or shock tests. However, its disadvantages are also obvious: the screw-fixing method is cumbersome and not conducive to mass production; using a bracket and screws to fix the GPU in the chassis wastes a lot of time during disassembly and assembly; for maintenance personnel, disassembling and replacing the GPU is also more complicated and time-consuming, which is not conducive to the normal operation of the machine; the screw design also makes the GPU bracket more difficult to manufacture, increases the manufacturing cost, and lengthens the processing cycle, which is not conducive to the control of product delivery time. Summary of the Invention

[0006] To address the problems of traditional server GPUs being secured with screws, which is cumbersome, unsuitable for mass production, and time-consuming, inefficient, and inefficient for GPU assembly and disassembly, this invention provides a tool-free GPU mounting bracket structure.

[0007] This invention is achieved through the following technical solution:

[0008] A tool-free GPU mounting bracket structure includes a middle bracket and a rear window panel mounted on the chassis base. A GPU mounting space is formed between the middle bracket and the rear window panel. A GPU bracket and a GPU tail bracket are respectively mounted on the front and rear ends of the GPU. The upper and lower parts of the GPU bracket are respectively provided with a GPU bracket bending part and a GPU bracket positioning plug. A spring pin is mounted on the GPU tail bracket.

[0009] The middle bracket has a sliding groove for the GPU tail bracket that can slide and guide the GPU tail bracket to be installed along the rear edge, and the upper part of the middle bracket has a positioning hole for the GPU tail bracket that can be engaged and positioned with a spring pin.

[0010] The lower part of the rear window shutter is provided with a plug slot that can be inserted and fitted with the GPU chip positioning plug; the upper part of the rear window shutter is equipped with a GPU latch module that can position and press the bent part of the GPU chip.

[0011] A further improvement of the present invention is that the GPU latch module includes a GPU latch base plate and a GPU pressing assembly positioned and installed on the upper side of the rear window panel. The GPU latch base plate is provided with a GPU latch positioning protrusion that can be inserted and fitted with a through hole on the bent portion of the GPU latch. The GPU pressing assembly is used to press and limit the bent portion of the GPU latch.

[0012] A further improvement of the present invention is that the GPU bonding assembly includes an intermediate baffle that is rotatably mounted to the upper side of the rear window baffle, and an upper baffle that is slidably mounted on the upper side of the intermediate baffle; a positioning post with an I-beam structure that slides through the intermediate baffle is mounted on the GPU latch base plate, and a gourd-shaped hole that can be slidably engaged with the positioning post of the I-beam structure is provided on the upper baffle.

[0013] A further improvement of the present invention is that the upper baffle has a guide hole in the left and right direction, and a connecting screw that is screwed into the guide hole to be installed with the middle baffle.

[0014] A further improvement of the present invention is that the upper baffle is provided with a locking block, and the upper side of the rear window baffle is provided with a locking groove that can lock and limit the locking block.

[0015] A further improvement of the present invention is that a tension spring is provided between the upper baffle and the middle baffle, and the tension spring has an elastic force that pulls the upper baffle in the locking direction.

[0016] A further improvement of the present invention is that the left and right side walls of the chassis base are positioned and installed with side wall grooves that can be slidably guided to the left and right sides of the centering bracket.

[0017] A further improvement of the present invention is that the sidewall groove has a plate-like structure, with sidewall groove bending portions bent inward on both sides to form a slide guide for sliding along the edge of the centering bracket; the upper edge of the sidewall groove bending portion is folded outward to form a guide flange.

[0018] A further improvement of the present invention includes a side wall slide groove positioning protrusion on the side wall slide groove and a side wall slide groove mounting hole on the side wall slide groove; a side wall slide groove screw hole and a side wall slide groove positioning hole that engages with the side wall slide groove positioning protrusion are provided on the side wall of the chassis base; the side wall slide groove screw hole and the side wall slide groove mounting hole are connected and installed by screws.

[0019] A further improvement of the present invention is that a cable management hole is provided on the rear side of the upper end of the middle bracket.

[0020] As can be seen from the above technical solutions, the beneficial effects of the present invention are:

[0021] The GPU tail bracket slide groove on the middle bracket allows for vertical sliding guidance and installation of the GPU tail bracket along its rear edge. The spring pin on the GPU tail bracket engages with the positioning socket on the middle bracket, ensuring reliable positioning and installation of the GPU rear end. The GPU bracket positioning plug engages with the plug slot at the bottom of the rear window panel, and the bent part of the GPU bracket is positioned and pressed in place by the GPU locking module, ensuring reliable positioning and installation of the GPU front end. Furthermore, the GPU locking module and spring pin allow for easy unlocking of the front and rear ends of the GPU, enabling tool-free disassembly and installation. This convenient and time-saving design significantly improves GPU maintenance efficiency and facilitates mass production. The overall structure is simple, easy to operate, and highly practical.

[0042] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0043] As shown in the figure, in an optional embodiment of the present invention, a tool-free GPU mounting bracket structure is disclosed, including a middle bracket 3 and a rear window baffle 2 mounted on a chassis base 1. The chassis base 1 has a U-shaped bent plate structure, and a GPU mounting space is formed between the middle bracket 3 and the rear window baffle 2. Multiple GPUs 5 can be installed side by side in the GPU mounting space. The end of the GPU mounting space closer to the rear window baffle 2 is the front end, and the end farther from the rear window baffle 2 is the rear end. A GPU baffle and a GPU tail bracket 6 are fixedly mounted at the front and rear ends of the GPU 5, respectively. The upper and lower parts of the GPU baffle are respectively provided with a GPU baffle bending part 52 and a GPU baffle positioning plug 51. The GPU baffle positioning plug 51 is vertically downward, and the GPU baffle bending part 52 is horizontally forward. The upper rear edge of the GPU tail bracket 6 is provided with a vertical GPU tail bracket bending part 62, and a spring pin 61 is installed on the GPU tail bracket bending part 62.

[0044] The middle bracket 3 is provided with a GPU tail bracket slide groove 33 that can guide the GPU tail bracket 6 to slide vertically along the rear edge, and the upper part of the middle bracket 3 is provided with a GPU tail bracket positioning hole 32 that can be inserted and positioned with the spring pin 61.

[0045] The lower part of the rear window panel 2 is provided with a plug slot 23 of a convex bridge structure that can be inserted and matched with the GPU plate positioning plug 51; the upper side of the rear window panel 2 is provided with a GPU latch module 7 that can position and press the GPU plate bending part 52.

[0046] The rear window baffle 2 and the middle bracket 3 are mounted opposite each other on the chassis base 1, forming a GPU mounting space. The GPU tail bracket slide groove 33 on the middle bracket 3 can vertically guide the GPU tail bracket 6 to slide and install. The spring pin 61 on the GPU tail bracket 6 (GPU tail bracket bending part 62) is inserted into the GPU tail bracket positioning hole 32 on the middle bracket 3, thereby achieving reliable positioning and installation of the rear end of the GPU 5 (GPU tail bracket 6). The GPU bracket positioning plug 51 is inserted into the plug slot 23 at the bottom of the rear window baffle 2, and the GPU bracket bending part 52 is positioned and pressed by the GPU locking module 7, thereby achieving reliable positioning and installation of the front end of the GPU 5 (GPU bracket). Furthermore, the GPU locking module 7 and spring pin 61 enable convenient unlocking of the front and rear ends of the GPU 5 (GPU baffle bending part 52 and GPU tail bracket bending part 62), thus achieving tool-free disassembly and installation of the GPU 5. This facilitates easy disassembly and assembly of the GPU 5, saving time and effort, and greatly improving the efficiency of GPU 5 maintenance and repair, which is beneficial for mass production. The overall structure is simple, easy to operate, and highly practical.

[0047] The chassis base 1 is made of sheet metal, which is easy to form and low in cost. The structural design has many circular through holes and raised bumps to improve the structural strength of the chassis. The chassis base 1 has horizontally bent chassis side wall bending parts 13 in the middle of the left and right side walls. The chassis side wall bending parts 13 can support and limit the installation of the middle bracket 3 and the rear window baffle 2, ensuring the reliability and stability of the installation of the middle bracket 3 and the rear window baffle 2.

[0048] The rear window baffle 2 is made of sheet metal and has an array of wide strip holes, as well as rectangular openings in other positions to expose the GPU5 socket. Several rear window baffle mounting holes 21 are provided on the left and right sides of the rear window baffle 2, and rear window baffle screw holes 14 are provided on the side walls of the chassis base 1. The rear window baffle 2 is reliably and accurately positioned and installed by screwing screws through the rear window baffle screw holes 14 and screwing them into the rear window baffle mounting holes 21.

[0049] Among them, the middle bracket 3 is made of zinc alloy and is processed by casting. It can be made into special shapes. After all the configurations are installed, the weight of the chassis will increase, which can easily cause the chassis to deform. The middle bracket 3 can improve the strength of the chassis.

[0050] The GPU5 has a protrusion at its rear end that is positioned and matched with the GPU rear bracket 6. The GPU is then fixed together with screws to ensure the accuracy and reliability of the connection between the GPU rear bracket 6 and the GPU5.

[0051] In the absence of external force, the spring pin 61 is in a released state due to the elasticity of its internal spring, which allows the internal pin shaft to automatically insert into the GPU tail bracket positioning socket 32 ​​to lock and ensure the reliability of positioning. By pulling the pin backward (overcoming the spring force), the pin can be easily unlocked from the GPU tail bracket positioning socket 32, thereby enabling tool-free disassembly and assembly of the GPU 5 rear end (GPU tail bracket 6).

[0052] Furthermore, such as Figure 8 As shown, since the GPU tail bracket 6 is pressed down onto the upper side of the middle bracket 3 from top to bottom, the lower side of the pin shaft end of the spring pin 61 has a chamfer (beveled surface), which helps to avoid jamming and failure to install properly during installation (by the upper edge of the middle bracket 3 abutting against the chamfered surface, the pin shaft of the spring pin 61 automatically retracts, falls down, and is locked into the positioning socket 32 ​​of the GPU tail bracket); the upper side of the pin shaft does not have a chamfer, which can effectively play a stopping role and has good reliability.

[0053] In another optional embodiment of the present invention, a tool-free GPU mounting bracket structure is disclosed, including a middle bracket 3 and a rear window baffle 2 mounted on a chassis base 1. The chassis base 1 has a U-shaped bent plate structure. A GPU mounting space is formed between the middle bracket 3 and the rear window baffle 2. Multiple GPUs 5 can be installed side by side in the GPU mounting space. The end of the GPU mounting space closer to the rear window baffle 2 is the front end, and the end farther from the rear window baffle 2 is the rear end. A GPU baffle and a GPU tail bracket 6 are fixedly mounted at the front and rear ends of the GPU 5, respectively. The upper and lower parts of the GPU baffle are respectively provided with a GPU baffle bending part 52 and a GPU baffle positioning plug 51. The GPU baffle positioning plug 51 is vertically downward, and the GPU baffle bending part 52 is horizontally forward. The upper rear edge of the GPU tail bracket 6 is provided with a vertical GPU tail bracket bending part 62, and a spring pin 61 is installed on the GPU tail bracket bending part 62.

[0054] The middle bracket 3 is provided with a GPU tail bracket slide groove 33 that can guide the GPU tail bracket 6 to slide vertically along the rear edge, and the upper part of the middle bracket 3 is provided with a GPU tail bracket positioning hole 32 that can be inserted and positioned with the spring pin 61.

[0055] The lower part of the rear window panel 2 is provided with a plug slot 23 of a convex bridge structure that can be inserted and mated with the GPU bracket positioning plug 51; the upper side of the rear window panel 2 is equipped with a GPU latch module 7 that can position and press the GPU bracket bending part 52. The GPU latch module 7 includes a GPU latch base plate 73 and a GPU pressing assembly 72 positioned and installed on the upper side of the rear window panel 2. The GPU latch base plate 73 is provided with a GPU bracket positioning protrusion 732 that can be inserted and mated with the through hole on the GPU bracket bending part 52. The GPU pressing assembly 72 is used to press and limit the GPU bracket bending part 52. The GPU bonding assembly 72 includes an intermediate baffle 724 that is rotatably mounted to the upper front edge of the rear window baffle 2. An upper baffle 721 is slidably mounted on the upper side of the intermediate baffle 724. A positioning post 733 with an I-beam structure that slides upward through the intermediate baffle 724 is mounted on the GPU latch base plate 73. The upper baffle 721 has a gourd-shaped hole 723 that can slide and engage with the positioning post 733 with the I-beam structure. The gourd-shaped hole 723 is set with the left side being larger than the right side.

[0056] The GPU tail bracket slide groove 33 on the middle bracket 3 can guide the vertical sliding installation of the GPU tail bracket 6 along its rear edge. The spring pin 61 on the GPU tail bracket 6 (GPU tail bracket bending part 62) is inserted into the GPU tail bracket positioning hole 32 on the middle bracket 3, thereby achieving reliable positioning and installation of the rear end of the GPU 5 (GPU tail bracket 6). The GPU bracket positioning plug 51 is inserted into the plug slot 23 at the bottom of the rear window panel 2. The GPU bracket bending part 52 is placed on the GPU latch base plate 73. The GPU bracket positioning protrusion 732 is inserted into the through hole on the GPU bracket bending part 52, and the GPU bracket bending part 52 is pressed and locked by the GPU pressing assembly 72 (the positioning post 733 of the I-shaped nail structure is located at the small end of the gourd hole 723, which can restrict the free rotation of the GPU pressing assembly 72), thereby achieving reliable positioning and installation of the front end of the GPU 5 (GPU bracket). The rear end of the GPU5 can be easily unlocked by operating the spring pin 61. By pushing the upper baffle 721 to the right, the positioning post 733 of the I-beam structure is aligned with the large end of the gourd hole 723. By flipping the entire GPU pressing assembly 72 upward, the pressing of the bent part 52 of the GPU baffle can be released, thus easily unlocking the front end of the GPU5. This enables tool-free disassembly and installation of the GPU5, making GPU5 disassembly and assembly convenient, saving time and effort, and greatly improving the efficiency of GPU5 maintenance and repair, which is beneficial for mass production. The overall structure is simple, easy to operate, and highly practical.

[0057] The GPU latch base plate 73 has positioning holes 731 at both ends, and the upper side of the rear window baffle 2 has a latch base plate positioning pin 22 that is positioned and inserted into the positioning holes 731 to ensure the convenience and accuracy of installing the GPU latch base plate 73. The two positioning holes 731 are in different positions, which can prevent the GPU latch base plate 73 from being fooled. The GPU latch base plate 73 is fixed to the upper side of the rear window baffle 2 by riveting with pull studs.

[0058] The intermediate baffle 724 has a roller 727 at its leading edge, and the upper leading edge of the rear window baffle 2 has a corresponding mounting hole. The rotating pin 71 is inserted into the roller 727 and the corresponding mounting hole, which can realize the flexible flipping of the GPU pressing assembly 72.

[0059] A foam strip is attached to the lower rear edge of the middle baffle 724. The foam strip can raise the middle baffle 724 to prevent the middle baffle 724 from failing to pop up and unlock.

[0060] In another optional embodiment of the present invention, a tool-free GPU mounting bracket structure is disclosed, including a middle bracket 3 and a rear window baffle 2 mounted on a chassis base 1. The chassis base 1 has a U-shaped bent plate structure. A GPU mounting space is formed between the middle bracket 3 and the rear window baffle 2. Multiple GPUs 5 can be installed side by side in the GPU mounting space. The end of the GPU mounting space closer to the rear window baffle 2 is the front end, and the end farther from the rear window baffle 2 is the rear end. A GPU baffle and a GPU tail bracket 6 are fixedly mounted at the front and rear ends of the GPU 5, respectively. The upper and lower parts of the GPU baffle are respectively provided with a GPU baffle bending part 52 and a GPU baffle positioning plug 51. The GPU baffle positioning plug 51 is vertically downward, and the GPU baffle bending part 52 is horizontally forward. The upper rear edge of the GPU tail bracket 6 is provided with a vertical GPU tail bracket bending part 62, and a spring pin 61 is installed on the GPU tail bracket bending part 62.

[0061] The middle bracket 3 is provided with a GPU tail bracket slide groove 33 that can guide the GPU tail bracket 6 to slide vertically along the rear edge, and the upper part of the middle bracket 3 is provided with a GPU tail bracket positioning hole 32 that can be inserted and positioned with the spring pin 61.

[0062] The lower part of the rear window panel 2 is provided with a plug slot 23 of a convex bridge structure that can be inserted and mated with the GPU bracket positioning plug 51; the upper side of the rear window panel 2 is equipped with a GPU latch module 7 that can position and press the GPU bracket bending part 52. The GPU latch module 7 includes a GPU latch base plate 73 and a GPU pressing assembly 72 positioned and installed on the upper side of the rear window panel 2. The GPU latch base plate 73 is provided with a GPU bracket positioning protrusion 732 that can be inserted and mated with the through hole on the GPU bracket bending part 52. The GPU pressing assembly 72 is used to press and limit the GPU bracket bending part 52. The GPU pressing assembly 72 includes a middle baffle 724 rotatably mounted to the upper front edge of the rear window baffle 2. An upper baffle 721 is slidably mounted on the upper side of the middle baffle 724. A positioning post 733 with an I-beam structure is mounted on the GPU latch base plate 73, which slides upward through the middle baffle 724. The upper baffle 721 has a gourd-shaped hole 723 that can slide and engage with the positioning post 733. The gourd-shaped hole 723 is larger on the left and smaller on the right. The upper baffle 721 has a guide hole 726 in the left and right directions. A connecting screw 722 is screwed into the guide hole 726 and screwed onto the middle baffle 724. By connecting the upper baffle 721 and the middle baffle 724 through the connecting screw 722, the upper baffle 721 can only slide left and right relative to the middle baffle 724 and cannot be separated, ensuring the reliability of unlocking and locking.

[0063] Specifically, the GPU tail bracket slide groove 33 on the middle bracket 3 can guide the vertical sliding installation of the GPU tail bracket 6 along its rear edge. The spring pin 61 on the GPU tail bracket 6 (GPU tail bracket bending part 62) is inserted into the GPU tail bracket positioning hole 32 on the middle bracket 3, thereby achieving reliable positioning and installation of the rear end of the GPU 5 (GPU tail bracket 6). The GPU bracket positioning plug 51 is inserted into the plug slot 23 at the bottom of the rear window panel 2. The GPU bracket bending part 52 is placed on the GPU latch base plate 73. The GPU bracket positioning protrusion 732 is inserted into the through hole on the GPU bracket bending part 52, and the GPU bracket bending part 52 is pressed and locked by the GPU pressing assembly 72 (the positioning post 733 of the I-beam structure is located at the small end of the gourd hole 723, which can restrict the free rotation of the GPU pressing assembly 72), thereby achieving reliable positioning and installation of the front end of the GPU 5 (GPU bracket). The rear end of the GPU5 can be easily unlocked by operating the spring pin 61. By pushing the upper baffle 721 to the right, the positioning post 733 of the I-beam structure is aligned with the large end of the gourd hole 723. By flipping the entire GPU pressing assembly 72 upward, the pressing of the bent part 52 of the GPU baffle can be released, thus easily unlocking the front end of the GPU5. This enables tool-free disassembly and installation of the GPU5, making GPU5 disassembly and assembly convenient, saving time and effort, and greatly improving the efficiency of GPU5 maintenance and repair, which is beneficial for mass production. The overall structure is simple, easy to operate, and highly practical.

[0064] In another optional embodiment of the present invention, a tool-free GPU mounting bracket structure is disclosed, including a middle bracket 3 and a rear window baffle 2 mounted on a chassis base 1. The chassis base 1 has a U-shaped bent plate structure. A GPU mounting space is formed between the middle bracket 3 and the rear window baffle 2. Multiple GPUs 5 can be installed side by side in the GPU mounting space. The end of the GPU mounting space closer to the rear window baffle 2 is the front end, and the end farther from the rear window baffle 2 is the rear end. A GPU baffle and a GPU tail bracket 6 are fixedly mounted at the front and rear ends of the GPU 5, respectively. The upper and lower parts of the GPU baffle are respectively provided with a GPU baffle bending part 52 and a GPU baffle positioning plug 51. The GPU baffle positioning plug 51 is vertically downward, and the GPU baffle bending part 52 is horizontally forward. The upper rear edge of the GPU tail bracket 6 is provided with a vertical GPU tail bracket bending part 62, and a spring pin 61 is installed on the GPU tail bracket bending part 62.

[0065] The middle bracket 3 is provided with a GPU tail bracket slide groove 33 that can guide the GPU tail bracket 6 to slide vertically along the rear edge, and the upper part of the middle bracket 3 is provided with a GPU tail bracket positioning hole 32 that can be inserted and positioned with the spring pin 61.

[0066] The lower part of the rear window panel 2 is provided with a plug slot 23 of a convex bridge structure that can be inserted and mated with the GPU bracket positioning plug 51; the upper side of the rear window panel 2 is equipped with a GPU latch module 7 that can position and press the GPU bracket bending part 52. The GPU latch module 7 includes a GPU latch base plate 73 and a GPU pressing assembly 72 positioned and installed on the upper side of the rear window panel 2. The GPU latch base plate 73 is provided with a GPU bracket positioning protrusion 732 that can be inserted and mated with the through hole on the GPU bracket bending part 52. The GPU pressing assembly 72 is used to press and limit the GPU bracket bending part 52. The GPU pressing assembly 72 includes a middle baffle 724 rotatably mounted to the upper front edge of the rear window baffle 2, and an upper baffle 721 slidably mounted on the upper side of the middle baffle 724. A positioning post 733 with an I-beam structure, which slides upward through the middle baffle 724, is mounted on the GPU latch base plate 73. The upper baffle 721 has a gourd-shaped hole 723 that can slide and engage with the positioning post 733, with the gourd-shaped hole 723 being larger on the left and smaller on the right. A tension spring 725 connects the upper baffle 721 and the middle baffle 724. The tension spring 725 exerts a pulling force on the upper baffle 721 in the locking direction (left). Without external force, the tension spring 725 ensures that the positioning post 733 is always aligned with the smaller end of the gourd-shaped hole 723, achieving reliable locking and preventing accidental unlocking. Furthermore, the upper baffle 721 has a locking block 728 bent upward at the leading edge, and the upper leading edge of the rear window baffle 2 has an L-shaped slot 24 that can lock and limit the locking block 728. The L-shaped bending direction of the slot 24 is consistent with the pulling direction of the tension spring 725, that is, to the left. When the GPU pressing assembly 72 is flipped open as a whole, the locking block 728 can be automatically and securely locked in the slot 24 under the tension of the tension spring 725, effectively preventing the GPU pressing assembly 72 from falling back, thereby increasing the convenience of disassembling and installing the GPU 5.

[0067] Specifically, the GPU tail bracket slide groove 33 on the middle bracket 3 can guide the vertical sliding installation of the GPU tail bracket 6 along its rear edge. The spring pin 61 on the GPU tail bracket 6 (GPU tail bracket bent part 62) is inserted into the GPU tail bracket positioning hole 32 on the middle bracket 3, thereby achieving reliable positioning and installation of the rear end of the GPU 5 (GPU tail bracket 6). The GPU bracket positioning plug 51 is inserted into the plug slot 23 at the bottom of the rear window panel 2. The GPU bracket bent part 52 is placed on the GPU latch base plate 73. The GPU bracket positioning protrusion 732 is inserted into the through hole on the GPU bracket bent part 52, and the GPU bracket bent part 52 is pressed and locked by the GPU pressing assembly 72 (through the tension of the tension spring 725, without the action of external force, the positioning post 733 of the I-shaped nail structure is at the small end of the gourd hole 723, which can restrict the free rotation of the GPU pressing assembly 72), thereby achieving reliable positioning and installation of the front end of the GPU 5 (GPU bracket). The rear end of the GPU5 can be easily unlocked by operating the spring pin 61. By pushing the upper baffle 721 to the right (overcoming the tension of the tension spring 725), the positioning post 733 of the I-beam structure is aligned with the large end of the gourd hole 723. By flipping the entire GPU pressing assembly 72 upwards, the locking block 728 automatically engages in the slot 24, releasing the pressure on the bent part 52 of the GPU baffle, thus easily unlocking the front end of the GPU5. This enables tool-free disassembly and installation of the GPU5, making GPU5 disassembly and assembly convenient, saving time and effort, greatly improving the efficiency of GPU5 maintenance, and facilitating mass production. The overall structure is simple, easy to operate, and highly practical.

The side wall sliding grooves 4 are plate-shaped structures with side wall sliding groove bending parts 41 bent inward on both sides to form sliding guides for the edges of the center bracket 3; the upper edge of the side wall sliding groove bending part 41 is folded outward with a guide flange; when the center bracket 3 is installed, its left and right sides are vertically guided and installed through the side wall sliding grooves 4, and the outward folded guide flange can realize the convenience of the installation of the center bracket 3; and the left and right sides of the center bracket 3 are provided with center bracket mounting holes 31, and screws pass through the left and right side walls of the chassis base 1 and are screwed into the center bracket mounting holes 31 to realize reliable positioning and installation of the center bracket 3.

[0071] Specifically, the rear window baffle 2 and the middle bracket 3 are mounted opposite each other on the chassis base 1, forming a GPU mounting space. The GPU tail bracket slide groove 33 on the middle bracket 3 can vertically guide the GPU tail bracket 6 to slide and install. The spring pin 61 on the GPU tail bracket 6 (GPU tail bracket bending part 62) is inserted into the GPU tail bracket positioning hole 32 on the middle bracket 3, thereby achieving reliable positioning and installation of the rear end of the GPU 5 (GPU tail bracket 6). The GPU bracket positioning plug 51 is inserted into the plug slot 23 at the bottom of the rear window baffle 2, and the GPU bracket bending part 52 is positioned and pressed by the GPU locking module 7, thereby achieving reliable positioning and installation of the front end of the GPU 5 (GPU bracket). Furthermore, the GPU locking module 7 and spring pin 61 enable convenient unlocking of the front and rear ends of the GPU 5 (GPU baffle bending part 52 and GPU tail bracket bending part 62), thus achieving tool-free disassembly and installation of the GPU 5. This facilitates easy disassembly and assembly of the GPU 5, saving time and effort, and greatly improving the efficiency of GPU 5 maintenance and repair, which is beneficial for mass production. The overall structure is simple, easy to operate, and highly practical.
