Description

Technical Field

[0001] The utility model belongs to the technical field of HUD tools, and in particular relates to an LCD screen fixing structure. Background Art

[0002] With the development of the times, more and more cars are equipped with HUD. LCD screen is an important component of HUD. In the prior art, some HUD LCD screens are fixed on the shell by liquid glue / double-sided tape or screws in combination with structural parts. Liquid glue / double-sided tape fixation requires glue to be applied, which places high requirements on the position of glue application. According to actual operations, glue application and pasting are prone to misalignment, which leads to error gaps in installation. At the same time, screw installation requires the use of tools, which is troublesome. According to actual experience, when the mounting hole is slightly misaligned, the screw can still be screwed into the mounting hole at a slight angle, which will also cause error gaps. Therefore, whether liquid glue / double-sided tape or screws are used for fixing, there will usually be assembly design gaps and production tolerances. Utility Model Content

DETAILED DESCRIPTION

[0026] This specific implementation is a LCD screen fixing structure, and its structural schematic diagram is as follows Figure 1-Figure 6 As shown, the LCD screen fixing structure installs the LCD screen 3 in the shell 1, wherein a diffuser 2 is installed inside the shell 1, and mounting holes are opened at the four corners of the diffuser 2. The inner wall of the back side of the shell 1 is fixedly connected with mounting posts 7 that match the mounting holes. The diffuser 2 can be installed inside the shell 1 by inserting the mounting posts 7 through the mounting holes. First, align the mounting holes of the diffuser 2 with the mounting posts 7 on the shell 1, and then insert the diffuser 2 through the mounting holes on the mounting posts 7 to complete the installation of the diffuser 2.

[0027] The LCD screen fixing structure includes a positioning assembly 5 for positioning the LCD screen 3 when it is installed. The positioning assembly 5 includes a first positioning block 51 fixedly connected to the inner bottom wall of the housing 1 and the left inner wall of the housing 1, and the side of the first positioning block 51 away from the back inner wall of the housing 1 is an inclined surface. The positioning assembly 5 also includes a positioning groove 52 opened on the left outer wall and the bottom outer wall of the LCD screen 3. A second positioning block 53 is fixedly installed inside the positioning groove 52. The side of the second positioning block 53 close to the housing 1 is set as an inclined surface matching the first positioning block 51.

[0028] After the diffuser 2 is installed inside the shell 1, the LCD screen 3 is installed. The positioning groove 52 provided on the LCD screen 3 is aligned with the first positioning block 51 on the shell 1. During the installation of the LCD screen 3 into the shell 1, the first positioning block 51 can enter the interior of the positioning groove 52 provided on the LCD screen 3 until the inclined surface provided by the first positioning block 51 contacts the inclined surface provided by the second positioning block 53. At this time, the LCD screen 3 has been installed into the shell 1. Therefore, during the installation of the LCD screen 3, the cooperation of the positioning groove 52 and the first positioning block 51 facilitates the installation of the LCD screen 3, can play a positioning role in the installation of the LCD screen 3, and can eliminate the assembly design gap and production tolerance.

[0029] The LCD screen fixing structure also includes an elastic buckle 6, which is used to play a preliminary limiting role for the LCD screen 3 after it is installed inside the shell 1. Three elastic buckles 6 are provided, two of which are symmetrically fixedly connected to the top of the shell 1, and the other elastic buckle 6 is fixedly connected to the right side of the shell 1. The end of the elastic buckle 6 away from the shell 1 is an arc-shaped end, and the end of the arc-shaped end extends to the inside of the shell 1. When the LCD screen 3 is installed, the arc-shaped end of the elastic buckle 6 is first flush with the inside of the shell 1 during the process of the LCD screen 3 entering the shell 1, so that the LCD screen 3 can enter the inside of the shell 1 conveniently. After the LCD screen 3 enters the inside of the shell 1, the elastic buckle 6 will be reset to be close to the outer wall of the LCD screen 3, so that the LCD screen 3 is preliminarily limited and fixed under the action of the elastic buckle 6.

[0030] The LCD screen fixing structure also includes a screen cover 4, which is installed on the shell 1 through a fixing component to further fix the LCD screen 3. The fixing component includes a card slot 41 opened at the top and bottom of the screen cover 4 and an elastic card buckle 42 fixedly connected to the top and bottom of the shell 1 and matched with the card slot 41. After the LCD screen 3 enters the interior of the shell 1 and is preliminarily fixed by the elastic buckle 6, the screen cover 4 is installed on the shell 1, the card slot 41 opened on the screen cover 4 is aligned with the elastic card buckle 42 on the shell 1, and then the screen cover 4 is horizontally pushed onto the shell 1. The screen cover 4 will first squeeze the elastic card buckle 42 during the movement on the shell 1. After the screen cover 4 is pushed into the shell 1, the elastic card buckle 42 is completely located in the card slot 41. At this time, the elastic card buckle 42 is no longer squeezed and begins to reset to its original state. At this time, with the cooperation of the card slot 41 and the elastic card buckle 42, the LCD screen 3 can be further fixed inside the shell 1.

[0031] In addition, a clearance groove for the protrusion of the LCD screen 3 to pass through is opened on the top of the screen cover 4, and a clearance groove for the protrusion of the LCD screen 3 to pass through is opened on the top of the shell 1; by opening the clearance groove on the shell 1, when the LCD screen 3 enters the interior of the shell 1, the protrusion on the LCD screen 3 passes through the clearance groove and extends to the outside of the shell 1, and at the same time, the clearance groove is opened on the screen cover 4, and the protrusion on the LCD screen 3 can be accommodated through the clearance groove when the screen cover 4 is installed.

[0032] In summary, the utility model firstly realizes the positioning of the LCD screen 3 during the installation process through the positioning component 5, which can eliminate the assembly design gap and production tolerance, and can play a preliminary limiting and fixing role on the LCD screen 3 through the elastic buckle 6, and then the LCD screen 3 can be further fixed through the screen cover 4, the installation process is simple, and the production efficiency is improved.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
