[0002] According to the current design trend of mainstream car manufacturers, in order to achieve an overall aesthetic, the central control entertainment display screen is mostly designed to be exposed on the dashboard. As more and more functions, and even content related to driving safety, are integrated into the display screen, the safety design of the display screen is particularly important. As an electronic product, the waterproof design of the display screen is the most important part of the entire product design. An excellent waterproof design can not only protect the electronic components of the display screen, but also improve its service life. For example, the utility model patent with announcement number CN223413847U discloses a vehicle display screen structure with built-in speaker, including a display screen, a control panel, a keypad, and a motherboard. By improving the control panel structure, a miniature speaker is embedded. Then, the keypad is adjusted, and the speaker is connected to the motherboard with a flexible cable. This achieves the purpose of embedding the speaker without modifying the external structure or the motherboard, without affecting the assembly with the train. It has the technical advantages of relatively low cost and short rectification cycle. However, this utility model lacks an auxiliary installation structure, requiring an additional hand to support the display screen during installation, making it inconvenient to use only the other hand. Furthermore, this display screen lacks a water inlet drainage structure, preventing water from draining in time after entering the screen, which can cause short circuits. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an installation structure for a vehicle-mounted central control entertainment display screen. This solves the technical problems of existing devices lacking an auxiliary installation structure, requiring an extra hand to support the display screen during installation, making installation inconvenient and necessitating the use of only the other hand. Furthermore, such displays lack a water inlet drainage structure, preventing timely drainage of water and leading to short circuits.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An installation structure for a vehicle-mounted central control entertainment display screen includes: The outer shell has an inner shell that can be detachably installed inside. A glass protective panel, in which an LCD panel is fixedly installed, and the LCD panel is detachably connected to the inner shell; Several connecting brackets are fixedly installed at their base on the rear wall of the outer casing, and screw holes are provided at the center of their upper wall. Two locating pins are fixedly installed at their base on the rear wall of the outer casing; Two retaining clips are fixedly mounted at their base on the rear wall of the housing and are adjacent to two locating pins.

[0005] Preferably, sealant is fixedly installed between the inner shell, the glass protective plate, and the outer shell.

[0006] Preferably, the sealant located between the inner shell and the outer shell is inclined from the center of the inner shell to both sides, and the sealant forms a flow channel with the inner shell and the outer shell. Drainage holes are provided on both sides of the outer shell, and the drainage holes are connected to the lowest point of the flow channel.

[0007] Preferably, the sealant is PUR adhesive.

[0008] Preferably, the upper edge of the inner shell is provided with a flow-guiding slope of one to two degrees, and the upper wall of the inner shell is provided with an auxiliary tilt angle of forty-five degrees to accelerate the water flow at the connection between the flow-guiding slope and the upper wall of the inner shell.

[0009] Preferably, a dustproof foam is fixedly connected inside the inner shell to the rear side of the LCD panel.

[0010] Beneficial effects This utility model provides an installation structure for an in-vehicle central control entertainment display screen, which has the following beneficial effects: The installation position is quickly locked by two positioning pins on the rear wall of the housing. Two adjacent fixing clips are pre-fixed to the dashboard. With the help of screw holes on several connecting brackets, precise fastening is achieved, which enhances the stability and firmness during the installation process. It can ensure that the installation position remains stable even after the operator touches the display screen, and the screw holes and the mounting holes on the dashboard will not shift. This solves the problem that existing vehicle display screens do not have an auxiliary installation structure, and require an extra hand to support the display screen during installation, which is very inconvenient. The water flow is guided by a one- to two-degree slope on the upper edge of the inner shell, and the 45-degree auxiliary tilt angle on the upper wall of the inner shell accelerates the water flow. PUR sealant prevents water from penetrating inward and guides it into the flow channel. Finally, the water is discharged through the drainage holes on both sides of the outer shell, preventing water from contacting the internal LCD panel and display components. At the same time, the dustproof foam between the display components and the LCD panel prevents dust from entering, thus providing both waterproof and dustproof protection. This solves the problem that existing vehicle display screens lack a water inlet drainage structure, which prevents water from being discharged in time and causes short circuits in the display screen.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Please see Figures 1-3 An installation structure for an in-vehicle central control entertainment display screen includes: The outer shell 1 has an inner shell 2 that can be detachably installed inside it; The glass protective plate 3 has an LCD panel 4 fixedly installed inside it, and the LCD panel 4 is detachably connected to the inner shell 2. Several connecting brackets 5 are fixedly installed at their base on the rear wall of the outer casing 1, and screw holes 6 are provided at the center of their upper wall. Two positioning pins 7 are fixedly installed at their bases on the rear wall of the outer casing 1; two fixing clips 8 are fixedly installed at their bases on the rear wall of the outer casing 1 and are adjacent to the two positioning pins 7.

[0015] When in use, the sealant 9 fills the gap between the inner shell 2, the glass guard plate 3, and the outer shell 1. This not only prevents dust, moisture, and other impurities from entering the interior and protects the LCD panel 4 from corrosion, but also acts as a buffer to offset the impact of vehicle vibration on various components, while improving the overall sealing and fit of the installation structure.

[0016] Please see Figure 3 Sealant 9 is fixedly installed between the inner shell 2, the glass guard plate 3, and the outer shell 1. When in use, the sealant 9 fills the gap between the inner shell 2, the glass guard plate 3, and the outer shell 1. It can prevent dust, moisture and other impurities from entering the interior and protect the LCD panel 4 from corrosion. It can also act as a buffer to offset the impact of vehicle vibration on various components, while improving the overall sealing and fit of the installation structure.

[0017] Please see Figure 3 The sealant 9 located between the inner shell 2 and the outer shell 1 is inclined from the center of the inner shell 2 to both sides. The sealant 9 forms a flow channel 10 with the inner shell 2 and the outer shell 1. Drainage holes 11 are provided on both sides of the outer shell 1, and the drainage holes 11 are connected to the lowest point of the flow channel 10. In use, the inclined design of the sealant 9 guides the small amount of liquid that may seep in to flow along the flow channel 10, and the drainage holes 11 discharge the liquid to the outside of the outer shell 1 in time, so as to avoid the liquid from accumulating inside and damaging the LCD panel 4, and further enhance the waterproof protection effect.

[0018] Please see Figure 3 The sealant 9 uses PUR adhesive. When used, PUR adhesive (polyurethane hot melt adhesive) has the characteristics of high bonding strength, excellent sealing performance, resistance to high and low temperatures, and anti-aging. It can adapt to the drastic temperature changes (high temperature in summer and low temperature in winter) and long-term vibration in the vehicle environment, ensuring that the sealant 9 can play a stable sealing and buffering role for a long time and is not easy to fall off or age and fail.

[0019] Please see Figure 3 The upper edge of the inner shell 2 has a drainage slope 12 of one to two degrees. The upper wall of the inner shell 2 is connected to the drainage slope 12 and has an auxiliary tilt angle 13 of forty-five degrees to accelerate the water flow. In use, the drainage slope 12 can guide the liquid at the top into the flow channel 10. The auxiliary tilt angle 13 accelerates the water flow speed by optimizing the angle of the flow channel 10. Together with the flow channel 10 formed by the sealant 9 and the drainage hole 11 of the outer shell 1, the overall drainage efficiency is improved and the risk of liquid residue is reduced.

[0020] Please see Figure 3 Inside the inner shell 2, a dustproof foam 14 is fixedly connected to the rear side of the LCD panel 4. When in use, the dustproof foam 14 can prevent dust from affecting the display effect or abrading the surface of the components, while also having a slight cushioning effect to reduce the impact of vibration on the connection between the two.

[0021] In Example 1, the installation position is quickly locked by two positioning pins 7 on the rear wall of the outer casing 1, and two adjacent fixing clips 8 are pre-fixed on the instrument panel. The screw holes 6 on several connecting brackets 5 are used to achieve precise fastening, which enhances the stability and firmness during the installation process. This ensures that the installation position remains stable even after the operator touches the display screen, and the screw holes 6 do not shift from the mounting holes on the instrument panel.

[0022] Specifically, during installation, first insert the two positioning pins 7 on the rear wall of the outer casing 1 into the preset holes on the instrument panel to quickly lock the installation position; the two adjacent fixing clips 8 are simultaneously engaged at the corresponding clips on the instrument panel to achieve pre-fixation. Even if the operator touches the display screen, the screw holes 6 can be precisely aligned with the mounting holes to avoid displacement.

[0023] Then, screws are screwed into the screw holes 6 on the connecting bracket 5 to lock it in place, firmly fixing the outer casing 1 to the dashboard. The entire installation process does not require additional auxiliary fixing, which saves time and improves the installation stability, completely solving the problem of displacement caused by contact during installation.

[0024] In Example 2, the water flow is guided by the drainage slope 12 of one to two degrees on the upper edge of the inner shell 2. The auxiliary tilt angle 13 of 45 degrees on the upper wall of the inner shell 2 accelerates the water flow. The sealant 9 of PUR material prevents the water flow from penetrating inward and guides it into the flow channel 10. Finally, the water flow is discharged through the drainage holes 11 on both sides of the outer shell 1, avoiding the water flow from contacting the internal LCD panel 4. At the same time, the dustproof foam 14 prevents dust from entering, thus providing both waterproof and dustproof protection.

[0025] Specifically, when water comes into contact with the display screen, the one- to two-degree drainage slope 12 on the upper edge of the inner shell 2 guides the water flow to both sides. When it flows through the forty-five-degree auxiliary tilt angle 13, the flow velocity increases, and it quickly flows into the flow channel 10 formed by the sealant 9, the inner shell 2, and the outer shell 1. The sealant 9, which uses PUR adhesive, prevents water from penetrating inward, while guiding the water flow along the flow channel 10 to both sides of the outer shell 1, and finally discharges it to the outside through the drainage hole 11, thus preventing water from contacting the LCD panel 4.

[0026] In addition, the dustproof foam 14 can block dust from entering, and the sealant 9 can also cushion vehicle vibrations, providing waterproof, dustproof and shockproof protection.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
