Description

Technical Field

[0001] This invention relates to the field of laptop hardware, and more specifically to an improved structure of the circuit board on which the CPU and GPU of a laptop are located. Background Technology

[0002] Laptops, due to their smaller size and greater portability compared to desktop computers, have become essential for many computer users. Current trends show a trend towards smaller size, lighter weight, and more powerful functionality. The main difference between laptops and desktops lies in portability, and laptops have different requirements for motherboards, CPUs, memory, graphics cards, and hard drive capacity.

[0003] In particular, the CPU (Central Processing Unit) and GPU (Graphics Processing Unit) are crucial components of a laptop's main configuration, and their combination directly affects the user experience. Currently, the CPU and GPU are soldered onto the same circuit board, requiring each configuration combination to have its own circuit board designed and manufactured. This is cumbersome in terms of design, manufacturing, and process management, lacks flexibility, and limits the user's upgrade options.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention

[0005] To address the aforementioned technical issues, we propose an improved structure for the circuit board housing the CPU and GPU of a laptop computer. By designing and manufacturing the CPU and GPU separately on two circuit boards and connecting them with a small connecting board, we increase the flexibility of the configuration.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] An improved structure for a laptop computer's CPU and GPU circuit board includes a CPU circuit board, a GPU circuit board, and a connecting board. The CPU is mounted on the CPU circuit board, and the GPU is mounted on the GPU circuit board. Each of the CPU and GPU circuit boards has an exposed contact. The connecting board has two elastic contacts, which make contact with the exposed contacts on the CPU and GPU circuit boards respectively, thereby enabling the connecting board to signal connect to both the CPU and GPU circuit boards.

[0008] Preferably, the connecting board has internal signal traces, and two elastic contacts on the connecting board are connected to components on the connecting board through the internal signal traces.

[0009] Preferably, both the CPU circuit board and the GPU circuit board are provided with a PCIe control bus, and the CPU and GPU are respectively connected to exposed contacts through the PCIe control bus on the CPU circuit board and the GPU circuit board.

[0010] Preferably, the PCIe control buses on both the CPU circuit board and the GPU circuit board are connected to external power supply and communication lines.

[0011] Preferably, the CPU circuit board and the GPU circuit board are symmetrically arranged on the outside of the connecting board.

[0012] Through the above technical solution, the present invention, by designing and manufacturing the CPU and GPU circuit boards separately and connecting them using a small connecting board, has the following beneficial effects:

[0013] 1. When different configurations are required, simply combine the two corresponding boards, making configuration combinations more flexible.

[0014] 2. The tests are mainly conducted on the CPU and GPU boards that serve as the basic configuration, eliminating the need to test each configuration from scratch, thus saving development time.

[0015] 3. Users can upgrade the required configurations individually without replacing the entire machine, providing greater upgrade potential.

[0016] 4. Repair is more convenient. Only the faulty CPU circuit board, GPU circuit board and related circuit boards in the connector board need to be repaired or replaced, saving repair costs. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0025] Example

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, an improved structure of a circuit board for a laptop computer's CPU and GPU includes a CPU circuit board 1, a GPU circuit board 2, and a connecting board 3. The CPU is mounted on the CPU circuit board 1, and the GPU is mounted on the GPU circuit board 2. Each of the CPU circuit board 1 and the GPU circuit board 2 has an exposed contact 4. The connecting board 3 has two elastic contacts 5, and the connecting board 3 contacts the exposed contact 4 on the CPU circuit board 1 and the exposed contact 4 on the GPU circuit board 2 through the two elastic contacts 5, thereby enabling the connecting board 3 to signal connect to both the CPU circuit board 1 and the GPU circuit board 2.

[0027] The connecting board 3 has an internal signal trace 6, and the two elastic contacts 5 on the connecting board 3 are connected to the components on the connecting board 3 through the internal signal trace 6.

[0028] Meanwhile, both the CPU circuit board 1 and the GPU circuit board 2 are equipped with PCIe control buses 7, and the CPU and GPU are respectively connected to the exposed contact 4 through the PCIe control buses 7 on the CPU circuit board 1 and the GPU circuit board 2.

[0029] In addition, the PCIe control bus 7 on both the CPU circuit board 1 and the GPU circuit board 2 is connected to an external power supply and communication line 8. The CPU circuit board 1 and the GPU circuit board 2 are symmetrically arranged on the outside of the connecting board 3.

[0088] In this example, the present invention designs and manufactures the circuit boards containing the CPU and GPU separately, and connects them using a connecting board 3. The CPU and GPU circuit boards are designed as two fully functional, power-supplying CPU circuit board 1 and GPU circuit board 2. In the circuit design, the lines for communication and power sharing between the CPU and GPU are symmetrically placed below the connector, and exposed contacts 4 are formed by exposing the surface contacts of the CPU circuit board 1 and GPU circuit board 2. The connecting board 3 has elastic contacts 5 underneath, which are fixed to the CPU circuit board 1 and GPU circuit board 2 with screws. After fixing, the elastic contacts 5 on the connecting board 3 will make close contact with the corresponding contacts on the CPU circuit board 1 and GPU circuit board 2, connecting the corresponding signal circuits together through the internal wiring of the connecting board 3, thus completing the connection and integration of the CPU circuit board 1 and GPU circuit board 2. Practice has shown that this design layout allows for more flexible configurations by simply combining the two required boards when different configurations are needed. During testing, the system can primarily focus on CPU-related and GPU-related components, eliminating the need to test every single component on the original PCB board from scratch, thus saving development time. Users can also upgrade individual components without replacing the entire system, providing greater upgrade flexibility. Repair is also more convenient; only the faulty CPU circuit board, GPU circuit board, and related circuit boards in the connecting panels need repair or replacement, saving on repair costs. This design achieves the goals of novelty, rational structure, and excellent application performance.

[0089] The above description is merely a preferred embodiment of the improved structure of the circuit board containing the CPU and GPU of a laptop computer according to the present invention. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
