[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0047] Combination Figures 1 to 5 As shown, the embodiment of the present disclosure provides a computer board fixing assembly, which includes: a computer box 20 and a computer board 10, the computer box 20 is provided with at least one guide column 21 and at least two buckles 22, the two buckles 22 are arranged opposite to each other, the two buckles 22 are respectively engaged with the two side walls of the computer board 10, the buckles 22 are used to limit the vertical movement of the computer board 10 and the movement along the relative directions of the two buckles 22, the guide column 21 is used to limit the horizontal movement of the computer board 10; the computer board 10 is provided with a guide column 21 that is suitable for the guide column 21. The computer box 20 is provided with a first through hole 111 matched with the guide column 21, and the number of the first through holes 111 is the same as that of the guide column 21 and they are arranged in a one-to-one correspondence; or, the computer box 20 is provided with at least two guide columns 21 and at least one buckle 22, the guide column 21 is used to limit the movement of the computer board 10 in the horizontal direction, the buckle 22 can be engaged with the side wall of the computer board 10, and the buckle 22 is used to limit the movement of the computer board 10 in the vertical direction; the computer board 10 is provided with a first through hole 111 matched with the guide column 21, and the number of the first through holes 111 is the same as that of the guide column 21 and they are arranged in a one-to-one correspondence.

[0048] According to the embodiment of the present disclosure, by providing the guide column 21 on the computer box 20, the guide column 21 can pass through the first through hole 111 to be connected and fixed with the computer board 10, and the computer board 10 can be quickly and accurately inserted into the computer box 20 without excessive position adjustment, thereby improving the convenience of positioning. By providing the buckle 22, the buckle 22 can easily fix the computer board 10 and the computer box 20 together without the use of additional tools, thereby greatly simplifying the installation process.

[0049] By setting a guide column 21 and two buckles 22, the buckle 22 can limit the vertical movement of the computer board 10, while the guide column 21 can limit the horizontal movement of the computer board 10. By setting the two buckles 22 relative to each other, the two buckles 22 can abut against the two opposite side walls of the computer board 10, thereby limiting the horizontal movement of the computer board 10 along the relative directions of the two buckles 22, thereby preventing the computer board 10 from rotating relative to the guide column 21. In this way, the computer board 10 can be fixed in all directions, making the position of the computer board 10 in the chassis more stable, reducing the risk of loosening or damage caused by vibration or impact; and no additional tools, such as screwdrivers or wrenches, are required, thereby reducing the risk of damage that may be caused during installation and improving installation efficiency.

[0050] By setting two guide columns 21 and a buckle 22, the buckle 22 can limit the vertical movement of the computer board 10, and the two guide columns 21 can limit the horizontal movement trend of the computer board 10, that is, the rotation or movement of the computer board 10 in the horizontal direction is restricted, and then the computer board 10 can be fixed in all directions, making the position of the computer board 10 in the chassis more stable, reducing the risk of loosening or damage caused by vibration or impact.

[0051] By fixing the computer board 10 and the computer box 20 with the guide column 21 and the buckle 22, the convenience of assembling the computer box 20 and the computer board 10 can be improved. The user only needs to align the computer board 10 with the guide column 21, and then push the computer board 10 in so that the buckle 22 is engaged with the side wall of the computer board 10. This installation method saves the tools and time required for using screws and screw holes, greatly improving the installation efficiency. It is also convenient for the user to disassemble. When the computer board 10 needs to be disassembled, it is only necessary to unfasten the buckle 22 from the side wall of the computer board 10, and then pull the computer board 10 out of the guide column 21.

[0052] Compared with the method of fixing the computer board 10 with four screw holes in the related art, the present embodiment, firstly, does not need to use screw holes and screws for fixing, which can effectively avoid the situation that the screw holes are damaged or worn during repeated installation or disassembly, resulting in the screws being unable to be firmly fixed in the screw holes, thereby increasing the risk of the computer board 10 moving in the chassis. And it can avoid the situation that the screws are too tight or too loose. Overtightened screws may damage the screw holes or the computer board 10, while overly loose screws cannot provide sufficient fixing force, causing the computer board 10 to shake or loosen in the chassis. Secondly, if the installation space is small, it may become difficult to install the screws, which will increase the assembly time of the computer board 10 and the computer box 20. Since the present embodiment does not need to use screws and screw holes, it avoids the problem of difficult installation during the installation process and the problem of static electricity that may be generated by the screws.

[0053] Specifically, during the actual installation process, the computer board 10 is configured to be assembled on the computer box 20 from top to bottom with the side where the first through hole 111 is located facing downward, so that the first through hole 111 is connected to the guide column 21, and then the computer board 10 is rotated downward with the side where the first through hole 111 is located as a fixed point until it is engaged with the buckle 22. In this way, the assembly convenience of the computer board and the computer box can be effectively improved, the assembly time can be shortened, and the assembly efficiency of the computer board 10 and the computer box 20 can be improved.

[0054] Optionally, the cross-section of the guide column 21 is circular, the cross-section of the guide column 21 may also be rectangular, triangular, etc. It can be understood that the cross-section shape of the guide column 21 is not unique.

[0055] Preferably, the cross section of the guide post 21 is circular, and the first through hole 111 is also circular. The diameter of the first through hole 111 is slightly larger than the diameter of the guide post 21 so that the two are compatible.

[0056] First, the contact between the guide post 21 with a circular cross section and the first through hole 111 on the computer board 10 is point contact. This contact mode can reduce friction resistance and make the computer board 10 slide more smoothly on the guide post 21. In contrast, shapes such as rectangles or triangles may cause line contact or surface contact, which will increase friction resistance. Secondly, when the guide post 21 with a circular cross section is subjected to pressure from the computer board 10, it can evenly disperse the pressure over the entire circumference, thereby avoiding stress concentration and possible damage. This uniform force also extends the service life of the guide post 21. Finally, when the guide post 21 with a circular cross section is matched with the circular through hole on the computer board 10, a certain degree of deviation can be allowed, because as long as the diameter of the through hole is slightly larger than the diameter of the guide post 21, the computer board 10 can be easily installed on the guide post 21, effectively improving the adaptability of the installation.

[0057] Optionally, when there are multiple first through holes 111 , the multiple first through holes 111 are located on the same side of the computer board 10 .

[0058] According to the embodiment of the present disclosure, when there are multiple first through holes 111, the multiple first through holes 111 are located on the same side of the computer board 10, that is, there are multiple guide plates, and the multiple guide posts 21 are located on the same side of the computer box 20. In this way, it is convenient to tilt the computer board 10 and install it with the computer box 20, and the convenience of connecting the electric control box and the computer box 20 is improved.

[0059] Specifically, combined Figure 1 and Figure 2 As shown in FIG. 1 , the number of the first through holes 111 is two, and the two first through holes 111 are both located at the right end of the computer board 10 .

[0060] Exemplary, combined Figures 1 to 5 As shown in the figure, the computer board 10 is provided with two first through holes 111, and the two first through holes 111 are both located at the right end of the computer board 10. The computer box 20 is provided with two guide columns 21, and the two guide columns 21 are both located at the right end of the computer box 20. The computer box 20 is provided with two buckles 22, and the two buckles 22 are arranged along the front and rear directions, and the two buckles 22 are respectively connected with the front side wall and the rear side wall of the computer board 10.

[0061] In this way, the reliability of the connection between the computer board 10 and the computer box 20 can be guaranteed.

[0062] Optionally, the guide column 21 is inclined vertically toward the side where the first through hole 111 is located at a preset angle, and the preset angle is greater than 0 degree and less than or equal to 5 degrees.

[0063] By adopting the embodiment of the present disclosure, by setting the guide column 21 to be tilted vertically toward the side where the first through hole 111 is located at a preset angle, the computer board 10 can be more easily inserted into the guide column 21 and aligned with the guide column 21, thereby reducing the difficulty of installing the first through hole 111 and the guide column 21 and improving the installation efficiency. By setting the preset angle to be greater than 0 degrees and less than or equal to 5 degrees, the installation convenience of the first through hole 111 and the guide column 21 can be improved while ensuring that the guide column 21 has sufficient structural strength.

[0064] Specifically, combined Figure 2 and Figure 3 As shown in FIG. 1 , the guide column 21 is arranged to be tilted to the right vertically, and the tilt angle to the right is 3 degrees.

[0065] In this way, the 3-degree tilt angle allows the computer board 10 to slide more smoothly into the guide column 21 during installation, reducing the time for the user to adjust the position and improving installation efficiency.

[0066] Optionally, the cross-sectional area of ​​the guide column 21 gradually increases from top to bottom.

[0067] According to the embodiment of the present disclosure, the cross-sectional area of ​​the guide column 21 is gradually increased from top to bottom, so that as the cross-sectional area gradually increases, the contact area between the guide column 21 and the computer board 10 also increases accordingly. This not only helps to provide better guiding performance, ensuring that the computer board 10 can slide more accurately along the guide column 21 during the insertion process, reducing deviation and misalignment to provide better support and guidance capabilities, but also makes the guide column 21 more stable when bearing the weight and impact force from the computer board 10, reducing the risk of breakage or deformation.

[0068] Optionally, the opening area of ​​the first through hole 111 gradually increases from top to bottom, and the maximum opening area of ​​the first through hole 111 is equal to the cross-sectional area of ​​the bottom surface of the guide post 21 .

[0069] According to the disclosed embodiment, the opening area of ​​the first through hole 111 is gradually increased from top to bottom, and the maximum opening area of ​​the first through hole 111 is equal to the cross-sectional area of ​​the bottom surface of the guide column 21. In this way, when the computer board 10 is installed in the electric control box, the inner wall surface of the first through hole 111 can contact the side wall of the guide column 21 in the up and down directions, ensuring the precise fit between the two. The precise fit means that there is no gap or looseness between the computer board 10 and the guide column 21, ensuring that the computer board 10 will not move relative to the electric control box in a vibration or impact environment. In addition, during the installation process of the computer board 10 and the electric control box, since the opening area of ​​the first through hole 111 is gradually increased, the computer board 10 can slide in more smoothly when inserted into the guide column 21, reducing friction and resistance. This not only makes the installation process easier, but also reduces the stress that may be generated during installation, thereby protecting the computer board 10 and the guide column 21.

[0070] Optionally, the top of the guide column 21 is chamfered.

[0071] According to the embodiment of the present disclosure, by providing a chamfer at the top of the guide column 21, the chamfer can guide the computer board 10 to be inserted into the guide column 21 more smoothly, reducing friction and resistance during installation, making the installation process easier, and thus improving the user's installation experience. Secondly, the chamfer makes the top of the guide column 21 smoother, which not only improves the overall aesthetics, but also avoids scratches or damage to the computer board 10 that may be caused by sharp edges or burrs.

[0072] Optionally, after the computer board 10 is connected to the computer box 20, the distance between the top surface of the guide column 21 and the end surface of the computer board 10 is a preset distance h, and the preset distance h is greater than or equal to 2 mm and less than or equal to 5 mm.

[0073] According to the embodiment of the present disclosure, the distance between the top surface of the guide column 21 and the end surface of the computer board 10 is set to a preset distance h, and the preset distance h is set to be greater than or equal to 2 mm and less than or equal to 5 mm. In this way, when the distance between the top surface of the guide column 21 and the end surface of the computer board 10 is greater than 5 mm, the length of the guide column 21 is too long to make it difficult for the user to disassemble it. When the distance between the top surface of the guide column 21 and the end surface of the computer board 10 is less than 2 mm, the length of the guide column 21 is too short to guide the computer board 10.

[0074] Preferably, the distance between the top surface of the guide column 21 and the end surface of the computer board 10 is 3 mm.

[0075] Optionally, the computer board 10 includes: a board body 11 and a radiator 12, the board body 11 is provided with a first through hole 111; the radiator 12 is connected to the board body 11, and the radiator 12 is located on a side away from the first through hole 111; wherein, the computer board 10 is provided with a first screw hole 112 at the end corresponding to the radiator 12, and the computer box 20 is provided with a second screw hole 23 at the position corresponding to the first screw hole 112, and the second screw hole 23 is adapted to the first screw hole 112 so that the computer board 10 and the computer box 20 are fixed by screws.

[0076] By adopting the embodiment of the present disclosure, by arranging the radiator 12 on the board body 11, the radiator 12 can dissipate heat for the electronic components on the board body 11, which helps to effectively dissipate the heat on the board body 11, thereby significantly improving the heat dissipation performance of the computer board 10 and preventing performance degradation or damage caused by overheating. By arranging the radiator 12 on the side away from the first through hole 111, the radiator 12 can be arranged on the side away from the connection between the board body 11 and the guide column 21, which facilitates the connection between the first through hole 111 and the guide column 21 and improves installation convenience. By arranging mutually compatible first screw holes 112 and second screw holes 23 on the computer board 10 and the computer box 20, and fixing them with screws, it can be ensured that the connection between the computer board 10 and the computer box 20 is firm and reliable, and the stability of the connection between the computer board 10 and the computer box 20 can be improved by fixing them together with screws, buckles 22 and guide columns 21.

[0077] Optionally, there are two first screw holes 112 , and the two first screw holes 112 are located at two opposite sides of an end of the computer board 10 where the heat sink 12 is disposed.

[0078] According to the embodiment of the present disclosure, two first screw holes 112 are provided, and the two first screw holes 112 are provided on both sides of the heat sink 12. In this way, the two first screw holes 112 can not only better spread the load of the heat sink 12, which helps to reduce the risk of deformation or damage caused by uneven weight distribution, but also the provision of the two first screw holes 112 enhances the connection stability between the computer board 10 and the heat sink 12, thereby preventing the computer board 10 from moving during transportation.
