Description

Technical Field

[0001] The utility model relates to a flat plate structure mounted on an agricultural machinery vehicle, in particular to an anti-seismic and waterproof structure of a screen module mounted on an agricultural machinery vehicle used for medium-sized industrial and agricultural electronic products. Background Art

[0002] Usually, the flat-panel display screen module mounted on agricultural machinery is a post-installed structure. The plastic cover wraps the display screen, and a screen steel sheet bracket is added inside to fix it. The waterproof method for the joint with the plastic cover is usually to add waterproof foam around the display screen module, and squeeze it through the screen steel sheet bracket to seal it on the plastic cover.

[0003] The environment in which vehicle-mounted flat panels are used in industry and agriculture is also relatively harsh. For example, when operating in heavy rain or on various rugged roads, when the agricultural machinery vehicle-mounted flat panel is vibrated by the vehicle, the internal metal steel sheet bracket will continuously impact the display screen, which is easy to damage the display glass. Over time, tiny cracks will appear. At the same time, it is also easy for the steel sheet bracket to deform slightly or cause the waterproof failure of the agricultural machinery vehicle-mounted flat panel display module area. Summary of the invention

[0004] In order to solve the above technical problems, the utility model provides a shockproof and waterproof structure for an agricultural machinery vehicle-mounted screen, which can solve the problem of the agricultural machinery vehicle-mounted flat panel being used in a long-term harsh environment and ensure the long-term effectiveness of the shockproof and waterproof properties of the display screen module area.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The invention discloses an anti-seismic and waterproof structure of an agricultural machinery vehicle-mounted screen, which is mainly composed of a display screen module, a front shell assembly, a screen silicone sleeve, a mainboard assembly, and a rear shell assembly.

[0007] The display screen module is located below the face shell assembly and is fixed and sealed by foam glue on the face shell assembly.

[0008] The screen silicone sleeve is located below the glass cover of the display screen module and is limited by the shape of the glass cover of the display screen module.

[0009] The mainboard assembly is located above the rear shell assembly and is fixed by screws.

[0010] The display screen module is wrapped by the face shell foam glue and the screen silicone cover, and forms an upper and lower sandwich structure with the face shell assembly and the rear shell assembly, thereby increasing the screen buffering and shock-resistant effect.

[0011] Furthermore, the display screen module compresses and supports the screen silicone cover of the display screen module through the bone position on the rear shell component.

[0012] Furthermore, the front shell assembly and the rear shell assembly are fixed by circumferential screws to provide a balanced pressing force for the display screen module.

[0013] The beneficial effects of the utility model are:

[0014] The utility model reduces the number of screen fixing brackets, reduces costs and increases efficiency. The whole machine becomes more convenient to disassemble, reduces the screen damage rate, improves after-sales maintainability, and indirectly reduces project development costs. The display screen module is sandwiched by the front shell and the back shell, and the structure is stable and reliable, which reduces the loosening of the vehicle-mounted tablet in a vibrating environment and improves safety and stability.
