[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] To solve the technical problem of signal interference caused by high-speed bus circuits to the display module, such as Figures 1 to 3 As shown, this application provides a chassis, including a chassis 1, a signal shielding partition 2, and a face shield 3. The chassis 1 has a mounting opening 11. The signal shielding partition 2 is connected to the mounting opening 11, and its size matches the mounting opening 11, completely covering the mounting opening 11 and effectively blocking electromagnetic interference generated inside the chassis 1. The face shield 3 is also connected to the mounting opening 11 and covers the outside of the signal shielding partition 2, forming a complete electromagnetic shielding structure together with the signal shielding partition 2. A first cavity for mounting a display module is formed between the signal shielding partition 2 and the face shield 3, and a second cavity for mounting a bus board is formed between the signal shielding partition 2 and the chassis 1. The two cavities are physically isolated by the signal shielding partition 2. The signal shielding partition 2 is provided with at least one cable pass-through hole 21, which connects the first cavity and the second cavity, allowing the power lines and signal lines of the display module to pass through the cable pass-through hole 21 and electrically connect to the bus board in the second cavity, while ensuring the integrity of the electromagnetic shielding effect. The chassis provided in this application achieves effective electromagnetic isolation between the display module and the bus board, ensures necessary electrical connections, and features a compact structure and reliable installation.

[0039] like Figure 1 and Figure 2As shown, in a specific embodiment of this application, the signal shielding partition 2 includes a partition portion 22 and a first partition flange 23. The partition portion 22 is a flat plate structure, the size of which matches the mounting opening 11, for achieving electromagnetic shielding. The first partition flange 23 extends along the two opposite edges of the partition portion 22, specifically it can be set on the upper and lower edges or the left and right edges of the partition portion 22. The first partition flange 23 is composed of a U-shaped flange body 231, which naturally forms a first slot 232 during the molding process. The size of the first slot 232 is adapted to the thickness of the side plate of the housing 1. By inserting the first slot 232 into the side plate of the housing 1 at the mounting opening 11, a stable connection between the signal shielding partition 2 and the housing 1 is achieved. This plug-in connection structure not only simplifies the assembly process but also improves the installation stability of the signal shielding partition 2, ensuring that it can maintain a good electromagnetic shielding effect even in a vibration environment.

[0040] like Figure 1 and Figure 2 As shown, in a specific embodiment of this application, the signal shielding partition 2 is further provided with a second partition flange 24, which together with the first partition flange 23 forms a complete edge connection structure. The second partition flange 24 extends along the other two opposite edges of the partition portion 22, forming a complementary installation layout with the first partition flange 23. The second partition flange 24 adopts an L-shaped flange body structure, and its bending angle matches the first box flange 12 on the side plate of the box 1. When the signal shielding partition 2 is installed to the installation opening 11, the L-shaped flange body of the second partition flange 24 overlaps with the first box flange 12. This overlapping structure not only enhances the positioning accuracy of the signal shielding partition 2, but also improves the mechanical strength of the overall structure. Through the combination of the insertion connection of the first partition flange 23 and the overlapping cooperation of the second partition flange 24, the signal shielding partition 2 is fixed in multiple directions on the box 1, effectively preventing displacement or loosening of the shielding partition during use, and ensuring the continuous stability of the electromagnetic shielding effect.

[0041] like Figure 1 and Figure 2As shown in a specific embodiment of this application, the second partition flange 24 and the first housing flange 12 are respectively provided with corresponding connecting through holes. The diameter and position of these connecting through holes are matched to ensure assembly accuracy. The chassis also includes fasteners 4, which are standard parts such as bolts or screws, and their diameter is adapted to the size of the connecting through holes. When the signal shielding partition 2 is installed to the housing 1, the fasteners 4 pass through the connecting through holes on the second partition flange 24 and the first housing flange 12 in sequence, and reliably connect the two by means of threaded fastening. This connection method not only realizes the mechanical fixation of the signal shielding partition 2 to the housing 1, but also facilitates disassembly operations during subsequent maintenance. The fastening force of the fasteners 4 can ensure a tight fit between the second partition flange 24 and the first housing flange 12, effectively eliminating assembly gaps, thereby ensuring the continuity of electromagnetic shielding. This connection structure, together with the plug-in connection of the first partition flange 23, constitutes a dual fixing system for the signal shielding partition 2, which can improve the stability and reliability of the overall structure.

[0042] like Figure 1 and Figure 2 As shown in a specific embodiment of this application, connecting protrusions 13 are provided on the side plate of the housing 1, and these connecting protrusions 13 are distributed at intervals along the edge of the side plate. When the face shield 3 is installed to the installation opening 11, the connecting protrusions 13 and the inner wall of the face shield 3 form an overlapping fit. The first partition flange 23 adopts a segmented structure arrangement, with appropriate intervals between each segment. When the signal shielding partition 2 is installed to the installation opening 11, the connecting protrusions 13 on the side plate of the housing 1 pass through the intervals between the segments of the first partition flange 23. This staggered structure does not affect the installation and fixation of the signal shielding partition 2, and also ensures a reliable overlap between the connecting protrusions 13 and the face shield 3.

[0043] like Figure 1 and Figure 2 As shown in a specific embodiment of this application, the connecting protrusion 13 and the face mask 3 are respectively provided with matching mating through holes. Fasteners pass sequentially through the mating through holes on the face mask 3 and the connecting protrusion 13, and the face mask 3 is fixedly connected to the housing 1 via a threaded connection. The diameter of the mating through holes is adapted to the diameter of the fastener 4, ensuring positioning accuracy and connection reliability during assembly. This connection method not only achieves mechanical fixation between the face mask 3 and the housing 1, but also facilitates alignment operations during assembly.

[0044] like Figure 1 and Figure 2As shown in a specific embodiment of this application, a second box body flange 14 is provided on the outer edge of the box body 1, and the flange structure extends circumferentially along the box body 1. Multiple mounting holes are evenly distributed on the second box body flange 14 for fixing the box body 1 to an external mounting surface using bolts or screws. During installation, a shock-absorbing pad can be installed between the second box body flange 14 and the mounting surface to reduce vibration transmission.

[0045] like Figure 1 and Figure 2 As shown, in a specific embodiment of this application, the second housing flange 14 maintains a certain distance from the side plate of the housing 1, forming a second slot 141. The width of the second slot 141 is adapted to the thickness of the first partition flange 23. When the signal shielding partition 2 is installed into the housing 1, the end of the first partition flange 23 is inserted into the second slot 141. This plug-in structure achieves multiple positioning of the signal shielding partition 2 and the housing 1, which improves assembly accuracy and enhances connection strength. After the first partition flange 23 extends into the second slot 141, its end forms a surface contact with the inner wall of the second housing flange 14, effectively dispersing structural stress and preventing local deformation. This structural design makes the connection between the signal shielding partition 2 and the housing 1 more stable and reliable, while facilitating alignment operations during assembly.

[0046] like Figure 1 and Figure 2 As shown, in one specific embodiment of this application, the partition portion 22 of the signal shielding partition 2 and the first housing folded edge 12 can have two relative positional relationships: the end face of the partition portion 22 is flush with the inner edge of the first housing folded edge 12, forming a continuous mounting reference surface; or, the partition portion 22 extends a certain distance into the housing 1 relative to the first housing folded edge 12. The specific arrangement can be selected according to actual installation requirements to meet the space requirements of different application scenarios while ensuring the installation reliability of the signal shielding partition 2.

[0047] This application also provides an electronic device that includes the chassis in the above embodiments, and therefore also has the advantages of the chassis in the above embodiments.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
