[0002] With the advancement of science and technology and the development of industrial production, electronic instruments and meters are increasingly used in various scenarios. Due to the complexity and diversity of these applications, the disadvantages of conventionally assembled chassis are obvious: large gaps at the joints make the internal electronic equipment susceptible to various electromagnetic interferences from the external environment; the use of screws for fixing makes the chassis structure prone to loosening and deformation in vibrating environments, easily causing internal compression and making it unreliable; and most reinforced chassis involve adding components, making assembly complex and not lightweight. Therefore, a new chassis structure has been designed and improved. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] like Figures 1 to 6 As shown, a chassis structure includes a chassis 1, a front panel 2, a rear panel 3, a mounting base 4, and a cover plate 5. The front panel 2 is detachably connected to the front end of the chassis 1 via screws; the rear panel 3 is detachably connected to the side of the chassis 1 away from the front panel 2 via screws; the mounting base 4 is detachably connected to the bottom inner side of the chassis 1 via screws; and the cover plate 5 is detachably connected to the top end of the chassis 1 via screws. This design makes the assembly of the entire chassis simpler, more robust, and more reliable.

[0031] Furthermore, the entire chassis structure, including the chassis 1, front panel 2, rear panel 3, mounting base plate 4, and cover plate 5, is made of aluminum alloy, making the whole machine lightweight, highly corrosion-resistant, and durable.

[0032] Furthermore, the entire chassis, including the chassis 1, front panel 2, rear panel 3, mounting base 4, and cover 5, is powder-coated or painted after assembly to ensure that all connections between components are direct metal-to-metal contact and to guarantee the overall conductivity of the chassis. Additionally, the entire chassis, including the chassis 1, front panel 2, rear panel 3, mounting base 4, and cover 5, undergoes overall sandblasting before powder-coating or painting, effectively increasing paint adhesion. Simultaneously, the front panel 2 is equipped with a display window, with a honeycomb perforated shielding cover 14 installed in the center. The rear panel 3 is equipped with honeycomb ventilation holes 31, forming a complete cage-like structure for the entire chassis, effectively dissipating heat and preventing electromagnetic interference and leakage.

[0033] Example 2

[0034] Based on embodiment 1, the front panel 2 is provided with a handle 21 to facilitate moving the body 1, that is, to facilitate moving the entire chassis structure.

[0035] The chassis 1 is formed by integral stamping and bending of sheet metal, with laser welding at the joints between surfaces. The mounting base 4 is installed inside the chassis, and several bosses are provided on the bottom surface of the chassis to support the mounting base 4. The mounting base 4 is used for mounting other components inside the chassis 1. Specifically, the bottom of the chassis 1 is stamped to form several bosses 11 for supporting and stabilizing the chassis 1. The positions of the bosses 11 can be reasonably increased, decreased, or unevenly distributed according to the weight distribution of the internal components, ensuring the mounting base 4 is securely fixed and effectively reducing vibration or resonance of the mounting base 4 itself, thus more effectively protecting internal precision components.

[0036] The two sides of the body 1 are formed by stamping to create grooves 13; this makes the entire assembled chassis structure sturdy, durable, not easily deformed, and shock resistant.

[0037] Furthermore, the connection between the body 1 and the cover plate 5 is filled with conductive foam 15, which can effectively avoid electromagnetic interference and electromagnetic leakage, and at the same time prevent the panel from vibrating or resonating.

[0038] Furthermore, spring ball head screws 12 are installed around the bottom of the mounting base plate 4. The height of the spring ball head screws 12 is adjustable, which can reduce shock and prevent scratches on the machine body 1 during production and installation, thus protecting the paint surface of the entire chassis structure.
