Abstract
Description
Technical Field
[0001] This utility model relates to the field of computer boards, and in particular to a novel computer core board. Background Technology
[0002] A circuit board is a type of printed circuit board, or PCB for short. It is manufactured with inserts that can be inserted into slots on the main circuit board of a computer to control the operation of hardware such as monitors and data acquisition cards. After installing drivers, the corresponding hardware functions can be realized. In industrial computers, unlike the circuit boards in home computers, in order to reduce the size of the computer and occupy less space in the machine, computer circuit boards that can be directly replaced are usually provided.
[0003] In the process of developing this application, the inventors discovered the following problems with the prior art:
[0004] In existing technologies, electronic components are usually directly soldered onto the surface of the circuit board. In order to ensure stable heat dissipation, the electronic components can only be exposed on the surface of the circuit board. When the circuit board is disassembled and transported, the electronic components on the surface of the circuit board are easily bumped and damaged. In addition, heat is continuously generated inside the circuit board during use. In existing technologies, heat dissipation is usually achieved only through surface ventilation, which is a low-efficiency heat dissipation method.
[0005] Therefore, those skilled in the art have provided a novel computer core board to solve the problems mentioned in the background section. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel computer core board that can protect the electronic components on the board surface and enhance the overall heat dissipation of the board.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A novel computer core board includes a PCB board. A locking mechanism is provided at each of the four corners of the upper surface of the PCB board. Each of the four locking mechanisms includes a fixing tube. Bolts are threaded inside each of the four fixing tubes. Springs are fixedly provided on the upper surface of the outer wall of each of the four fixing tubes. Locking blocks are movably sleeved on the upper surface of the outer wall of each of the four fixing tubes.
[0009] A protective cover is movably provided on the upper surface of the PCB board. A sliding groove is provided on one side of both the front and rear ends of the upper surface of the protective cover. A locking groove is provided on both ends of the two sliding grooves and on the other side of both the front and rear ends of the upper surface of the protective cover. A heat-conducting plate is movably provided on the lower surface of the PCB board. Multiple heat dissipation fins are fixedly provided on the lower surface of the heat-conducting plate.
[0010] Furthermore, the four fixing tubes are respectively fixedly embedded at the four corners of the upper surface of the PCB board, and the upper ends of the four springs are respectively fixedly connected to the top surface of the inner wall of the four locking blocks.
[0011] Furthermore, the four fixed tubes are movably disposed inside the six locking slots, and the four locking blocks are respectively embedded inside the four locking slots of the six locking slots.
[0012] Furthermore, a fixing panel is fixedly provided on the rear end face of the PCB board, and screws are threadedly embedded on both sides of the center of the rear end face of the fixing panel.
[0013] Furthermore, the heat-conducting plate is made of brass, and slots are provided at the four corners of the lower end face of the heat-conducting plate, with the four fixing tubes respectively embedded in the four slots.
[0014] Furthermore, protrusions are fixedly provided at both ends of the outer wall of the four fixed tubes, and grooves are provided at both ends of the inner wall of the four locking blocks, with the protrusions slidingly disposed inside the grooves respectively.
[0015] Furthermore, the protective cover has multiple ventilation slots on its surface, and the protective cover is made of brass.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model proposes a novel computer core board. After the electronic components are soldered onto the PCB board, the locking block is pulled upward to disengage it from the locking groove. Then, the protective cover is slid to one side to cover multiple electronic components. The locking block is then released to allow it to reset under the action of the spring and embed into the locking groove, thereby achieving the effect of fixing the position of the protective cover. The protective cover can protect the electronic components exposed on the outside of the PCB board and prevent them from being damaged by scratches and collisions.
[0018] 2. The present invention proposes a novel computer core board in which four fixing tubes are located at the bottom of the PCB board and pass through the four corners of the upper surface of the heat-conducting plate. Then, four bolts are rotated to thread them into the four fixing tubes. The combination and fixing of the substrate and the heat-conducting plate can be achieved by the bolts. Since the heat-conducting plate has excellent heat conduction and can increase the heat transfer area and improve the heat transfer efficiency through heat dissipation fins, the heat dissipation efficiency of the PCB board can be improved.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Reference Figures 1 to 6 One embodiment provided by this utility model:
[0029] A novel computer core board includes a PCB board 1. Locking mechanisms 3 are provided at the four corners of the upper surface of the PCB board 1. Each of the four locking mechanisms 3 includes a fixing tube 303. Bolts 304 are threaded inside each of the four fixing tubes 303. Springs 302 are fixedly provided on the upper surface of the outer wall of each of the four fixing tubes 303. Locking blocks 301 are movably sleeved on the upper surface of the outer wall of each of the four fixing tubes 303.
[0030] A protective cover 4 is movably provided on the upper end face of the PCB board 1. Slide grooves 7 are provided on one side of both the front and rear ends of the upper end face of the protective cover 4. Locking grooves 6 are provided on both ends of the two slide grooves 7 and on the other side of both the front and rear ends of the upper end face of the protective cover 4. A heat-conducting plate 2 is movably provided on the lower end face of the PCB board 1. Multiple heat dissipation fins 8 are fixedly provided on the lower end face of the heat-conducting plate 2.
[0031] Specifically, the locking mechanism 3 enables the unlocking and fixing of the protective cover 4, while facilitating the installation, disassembly, and cleaning of the heat-conducting plate 2 and the heat dissipation fins 8. The protective cover 4 protects the exposed electronic components on the surface of the PCB board 1 without affecting its heat dissipation efficiency. The heat-conducting plate 2 and the heat dissipation fins 8 increase the heat conduction area and enhance the overall heat dissipation efficiency.
[0032] Reference Figure 4 Four fixing tubes 303 are fixedly embedded at the four corners of the upper surface of the PCB board 1, and the upper ends of the four springs 302 are fixedly connected to the top surface of the inner wall of the four locking blocks 301.
[0033] Specifically, pulling the locking block 301 upwards stretches the spring 302, and releasing the locking block 301 resets it under the action of the spring 302.
[0034] Reference Figure 1 , Figure 2 , Figure 5 Four fixed tubes 303 are respectively movably disposed inside the six locking slots 6, and four locking blocks 301 are respectively embedded inside the four locking slots 6.
[0035] Specifically, by embedding the locking block 301 inside the locking groove 6, the locking block 301 can be used to fix the position of the protective cover 4.
[0036] Reference Figure 5 A fixing panel 5 is fixedly installed on the rear end face of the PCB board 1, and screws are threadedly embedded on both sides of the center of the rear end face of the fixing panel 5.
[0037] Specifically, screws can fix the device in the installation position and connect it to external equipment through the fixing panel 5. This is a mature existing technology, so it will not be described in detail.
[0038] Reference Figure 1 , Figure 6 The heat-conducting plate 2 is made of brass, and slots are provided at the four corners of the lower end face of the heat-conducting plate 2. The four fixing tubes 303 are respectively embedded in the four slots.
[0039] Specifically, the excellent thermal conductivity of brass can improve the heat dissipation efficiency of PCB board 1, while the design of embedding the fixing tube 303 into the slot can initially fix the position of the heat conduction plate 2.
[0040] Reference Figure 4 Each of the four fixed tubes 303 has a protrusion fixedly installed at both ends of the outer wall, and each of the four locking blocks 301 has a groove at both ends of the inner wall, with the protrusions slidingly installed inside the grooves.
[0041] Specifically, the engagement of the protrusion and the groove prevents the locking block 301 from rotating, thereby preventing the locking block 301 from twisting the spring 303 and causing it to age faster.
[0042] Reference Figure 1 , Figure 2 , Figure 3 The protective cover 4 has multiple ventilation slots on its surface and is made of brass.
[0043] Specifically, the brass protective cover 4 can play a certain role in heat dissipation. The multiple ventilation slots on the surface of the protective cover 4 can play a protective role without affecting the heat dissipation of the PCB board 1 and electronic components.
[0044] Working principle: The heat-conducting plate 2 is placed on the lower end of the PCB board 1, and the four fixing tubes 303 pass through the four slots at the four corners of the heat-conducting plate 2. Then, the bolts 304 are screwed into the fixing tubes 303 to complete the installation and fixation of the heat-conducting plate 2. The heat-conducting plate 2, together with the heat dissipation fins 8, can expand the heat dissipation area and improve the heat conduction efficiency, thereby improving the heat dissipation efficiency of the PCB board 1. After the electronic components are soldered to the upper end of the PCB board 1, the two locking blocks 301 located inside the slide groove 7 are pulled upward to disengage them from the two locking slots 6. Then, the protective cover 4 is slid to one side and the two locking blocks 301 on the other side are pulled upward. When the two fixing tubes 303 at the lower end of the two locking blocks 301 on the other side are respectively inserted into the two locking slots 6 on one side, the locking blocks 301 are released so that they retract under the action of the spring 302 and are inserted into the locking slots 6, thereby achieving the effect of fixing the position of the protective cover 4. Then, the protective cover 4 can protect the exposed electronic components.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
