Description

Multifunctional key waterproof structure of vehicle-mounted comprehensive screen Technical Field The utility model relates to a vehicle-mounted flat plate structure, in particular to a vehicle-mounted full-screen multifunctional key waterproof structure used for industrial and agricultural medium-sized electronic products. Background At present, the on-vehicle comprehensive screen panel button of agricultural machinery is mainly located the radiating piece face, and the function is also more single, and agricultural machinery operational environment is abominable, and rainy day and dust can influence the screen display effect, and at this moment, the button is in visual field blind area, and the driver hardly touches panel button function, and the operation is easy misjudgement. The keys of the traditional agricultural machinery vehicle-mounted flat screen are larger, the arrangement is scattered, the stacking layout of the whole agricultural machinery structure is seriously affected, and the appearance and the shape are also relatively bloated. Disclosure of Invention In order to solve the technical problems, the utility model provides a vehicle-mounted full-screen multifunctional key waterproof structure, solves the problem of misjudgment of full-screen key touch of vehicle-mounted equipment, and provides a screen touch operation alternative scheme for severe working environments. The technical scheme adopted for solving the technical problems is as follows: a multifunctional key waterproof structure for a vehicle-mounted comprehensive screen mainly comprises a display screen module, a face shell assembly, a key assembly, a main board assembly and a rear shell assembly. The key assembly is arranged below the face shell assembly and is assembled with the key hole on the face shell assembly in a limiting mode through the key cap. The key assembly comprises keys, a key support and a key FPC. The key comprises a key cap and TPU soft rubber, and 6 key caps and TPU soft rubber are integrally formed through double-shot injection molding. The key support is located below the key assembly, is assembled through limiting of the locating column on the face shell assembly, and is fixed by means of screw locking. The button FPC is assembled through the limiting of the locating column on the button support and fixed on the button support through screw locking. The main board assembly is located above the rear shell assembly and is fixed through screw locking. The key positions on the right side of the face shell component are designed to be in large-inclined-plane transition, and the key caps are not higher than the screen, so that false touch caused by front collision of the whole machine is avoided. Further, the display screen module is located above the face shell assembly and is fixedly sealed through foam adhesive. Furthermore, the button FPC is connected through the mainboard shrapnel, so that the function signal transmission is realized. Further, the key assembly is located on the right side of the screen, and 6 functional key caps are distributed at the middle positions of 3 screw posts on the right side of the face shell assembly, so that the width of the whole machine is reduced. Further, the keys are contacted with the face shell component through TPU soft rubber, and the TPU soft rubber is pressed by the key support to seal and prevent water. Furthermore, the TPU soft rubber is independently provided with a sealing bin at the positions of 6 function keys, and each function key is independently sealed. Furthermore, 7 screw hole sites on the button support are evenly distributed on two sides of the button, so that a pressing plane is formed, Z-direction pressure is provided for each functional button, and waterproof sealing stability is improved. The beneficial effects of the utility model are as follows: The key is positioned on the right side of the screen, the whole machine occupies small proportion, the visual effect has small overall influence on the whole screen, and the beautiful degree of the whole machine is improved.
