Description

Technical Field

[0001] This utility model relates to the field of automotive dashboard technology, and in particular to the installation structure of an LCD screen on a dashboard. Background Technology

[0002] A car's instrument panel consists of various gauges and indicators, especially driver warning lights and alarms, which provide the driver with the necessary information on the car's operating parameters.

[0003] In the current technology, the use of electronic structures in automotive instrument panels is quite common. To reduce costs, a combination of mechanical and electronic components is typically employed. Mechanical gauges are located on both sides, with an LCD screen in the center to display information.

[0004] Traditional LCD screens are inserted into the instrument panel housing on one side and fixed with screws on the other. After the vehicle has been driven for a certain period of time, the screws may loosen due to vehicle bumps, which can cause the LCD screen to loosen and affect its reliability. Utility Model Content

[0005] The purpose of this utility model is to provide an installation structure for an LCD screen on an instrument panel.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: the mounting structure of the LCD screen on the instrument panel includes a mounting base set on the chassis, each of the four corners of the mounting base is provided with an oblique rectangular groove, a rectangular block is inserted into the rectangular groove from top to bottom, a triangular groove is provided on the side of the rectangular block facing the mounting base, and the four corners of the LCD screen are respectively inserted into the triangular groove; a through groove is provided in the rectangular groove, and a pressure rod abutting against the top of the rectangular block is provided in the through groove.

[0007] The mounting base is further configured such that: a decorative frame is provided on the mounting base, barbs are provided on the periphery of the decorative frame, and a slot is provided on the inner wall of the mounting base, with the barbs hooking into the slot.

[0008] The decorative frame is further configured such that an elastic rubber layer is provided on its lower surface, and a rigid strip is provided on the elastic rubber layer, with the rigid strip abutting against the pressure bar.

[0009] The design further includes: the upper part of the pressure bar is semi-circular, and the rigid strip is provided with a semi-circular groove that matches the upper part of the pressure bar.

[0010] Further configuration: An elastic rubber block is provided at the bottom of the rectangular groove.

[0011] In summary, this utility model has the following beneficial effects: the installation structure of the LCD screen on the dashboard can reduce the problem of screw loosening caused by vehicle bumps after a certain period of driving, reduce the possibility of LCD screen loosening, and ensure the reliability of LCD screen fixing.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] The mounting structure for the LCD screen on the dashboard includes a mounting bracket mounted on the chassis, which is recessed.

[0018] The mounting base has angled rectangular slots at each of its four corners, into which rectangular blocks can be inserted from top to bottom. Each rectangular block has a triangular slot on one side. The four corners of the rectangular LCD screen abut against these triangular slots, and then all four rectangular blocks are inserted into the rectangular slots together, thus fixing the LCD screen horizontally.

[0019] Two oblique and opposite through slots are provided on the inner wall of the rectangular groove, and pressure rods are inserted through the through slots. The pressure rods abut against the top of the rectangular block, thereby fixing the LCD screen in the vertical direction, and together with the rectangular block in the horizontal direction, achieving overall fixation of the LCD screen.

[0020] The pressure bar can be of two types. One type is a one-piece pressure bar, in which a spring is installed in one of the slots, thus positioning the pressure bar between the two slots to press down on the rectangular block. The other type is a split pressure bar, in which two pressure bars are inserted into the slots by interference fit to press down on the rectangular block. The figure shows a one-piece pressure bar.

[0021] The mounting base has a rectangular decorative frame that covers the rectangular groove. The decorative frame has downward-pointing barbs on its perimeter, and the mounting base has a slot on its inner wall. The barbs hook into the slot, thus securing the decorative frame.

[0022] The decorative frame also serves to hold down the pressure bar. Specifically, the lower surface of the decorative frame has an elastic rubber layer, on which a rigid strip is placed, which abuts against the pressure bar. The top of the pressure bar is semi-circular, and the rigid strip has a semi-circular groove that fits the top of the pressure bar. The semi-circular groove facilitates the pressing of the pressure bar and ensures that the rigid strip abuts against the pressure bar.

[0023] The bottom of the rectangular groove is equipped with an elastic rubber block. The elasticity of the elastic rubber block, together with the elastic rubber layer, can reduce loosening caused by vehicle bumps and ensure stable and reliable installation of the LCD screen.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
