Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, specifically to a frame panel sealing mechanism for a vehicle display. Background Technology

[0002] In-vehicle displays are electronic devices installed inside vehicles to provide various information and entertainment functions. They are mainly divided into two types: central control displays and instrument panel displays. The central control display is the core display and control interface of the vehicle, usually located in the center of the dashboard. The instrument panel displays various vehicle parameters and status information, such as vehicle speed, fuel consumption, and water temperature, providing real-time feedback to help the driver better understand the vehicle's condition. During production, workers need to install the display screen inside the frame. Because there are some delicate electronic components inside the display screen, it needs to be sealed to prevent external moisture from entering and affecting the operation of these delicate electronic components.

[0003] However, existing methods for sealing displays inside vehicle display frames typically involve compressing solid sealing rings. Once installed, this method applies constant pressure to the sealing ring, which cannot be adjusted later. As the vehicle display is used over time and subjected to constant vibrations inside the vehicle, the sealing rings age. In extremely cold weather, the sealing rings shrink due to temperature variations, further reducing the sealing effect and allowing moisture to enter the display. Therefore, this method does not meet current requirements. To address this, we propose a new sealing mechanism for the frame panel of vehicle displays. Utility Model Content

[0004] The purpose of this utility model is to provide a frame panel sealing mechanism for a vehicle-mounted display screen, in order to solve the problem mentioned in the background art where workers typically use a solid sealing ring to seal the display screen when installing it inside the frame. Once installed, the pressure on the solid sealing ring is constant and cannot be changed later. As the vehicle-mounted display screen is used for a long time and is subjected to vibrations inside the vehicle, the solid sealing ring will age to some extent. In extremely cold weather, the solid sealing ring will shrink to some extent due to temperature, which will reduce the sealing effect of the display screen and allow some moisture to enter the interior of the vehicle-mounted display screen.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a frame panel sealing mechanism for a vehicle-mounted display screen, comprising a lower frame body for the vehicle-mounted display screen:

[0006] The upper frame of the vehicle display screen is installed on the upper end of the lower frame of the vehicle display screen. Hollow rubber sealing rings are installed inside the lower frame and the upper frame of the vehicle display screen, and insulating oil is provided inside the hollow rubber sealing rings.

[0007] A hollow expansion boss is located at the lower end of both sides of the hollow rubber sealing ring. A limit pin is fixedly installed at one end of the hollow expansion boss. The limit pin is slidably connected to the lower frame body of the vehicle display screen through a slot. A sealing adjustment hexagonal screw is threadedly installed at the upper end of the upper frame body of the vehicle display screen. A pressure adjustment plate is rotatably connected to the lower end of the sealing adjustment hexagonal screw. Limit inserts are fixedly installed on both sides of the lower end of the upper frame body of the vehicle display screen.

[0008] Preferably, the inner limiting plate is provided with limiting fitting holes inside, and there are three limiting fitting holes.

[0009] Preferably, a limiting boss is fixedly installed at the lower end of the lower frame body of the vehicle display screen and the upper end of the upper frame body of the vehicle display screen.

[0010] Preferably, both sides of the lower frame of the vehicle display screen are equipped with mating bosses, which are fixedly connected to the lower frame of the vehicle display screen.

[0011] Preferably, the inner side of the hollow rubber sealing ring is provided with the display screen body, and the outer side of the display screen body is in contact with both the mating boss and the limiting boss.

[0012] Preferably, the hollow rubber sealing ring is connected to both the lower frame body and the upper frame body of the vehicle display screen via slots.

[0013] Preferably, both sides of the upper surface of the lower frame of the vehicle display screen are provided with embedded grooves, and the limiting embedded plate extends into the embedded grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by installing a hollow rubber sealing ring and placing insulating oil inside it, facilitates the adjustment of the internal pressure of the hollow rubber sealing ring. This allows the insulating oil to evenly distribute the pressure throughout the hollow rubber sealing ring, causing it to expand simultaneously and seal the device. The installation of the sealing adjustment hexagonal screw allows operators to control the position of the pressure adjustment plate, which in turn applies localized pressure to the hollow rubber sealing ring. This further amplifies the pressure, allowing the insulating oil inside to evenly distribute the pressure, resulting in simultaneous expansion and enhanced sealing. This design enables subsequent sealing adjustments, reduces the impact of aging on the vehicle display screen, and allows the solid sealing ring to expand in extremely cold weather to compensate for the reduced sealing strength, preventing moisture from entering the vehicle display screen.

[0016] 2. By installing a limiting insert plate, this utility model allows the insulating oil to expand the hollow expansion boss when the pressure regulating plate compresses the hollow rubber sealing ring, causing the hollow expansion boss to elongate. This, in turn, causes the hollow expansion boss to push the limiting pin shaft to move, locking the limiting pin shaft inside the limiting mating hole. This, in turn, stably connects the lower frame body of the vehicle display screen and the upper frame body of the vehicle display screen together, achieving internal self-locking and making the device look neater and more aesthetically pleasing.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 The present invention provides an embodiment of a frame panel sealing mechanism for a vehicle-mounted display screen, comprising a lower frame body 1 of the vehicle-mounted display screen.

[0024] The upper frame body 2 of the vehicle display screen is installed on the upper end of the lower frame body 1 of the vehicle display screen. Hollow rubber sealing rings 7 are installed inside the lower frame body 1 and the upper frame body 2 of the vehicle display screen. Installing hollow rubber sealing rings 7 and filling them with insulating oil can facilitate the device to adjust the internal pressure of hollow rubber sealing rings 7, so that the insulating oil can evenly transmit the pressure to all parts of hollow rubber sealing rings 7, thereby causing all parts of hollow rubber sealing rings 7 to expand simultaneously, so that hollow rubber sealing rings 7 can seal the device and ensure the sealing effect of the device. Insulating oil is filled inside hollow rubber sealing rings 7.

[0025] Hollow expansion bosses 8 are located at the lower ends of both sides of the hollow rubber sealing ring 7. A limiting pin 9 is fixedly installed at one end of each hollow expansion boss 8. The limiting pin 9 is laterally slidably connected to the lower frame body 1 of the vehicle display screen via a slot. A sealing adjustment hexagonal screw 4 is threadedly installed at the upper end of the upper frame body 2 of the vehicle display screen. Installing the sealing adjustment hexagonal screw 4 allows the operator to control the position of the pressure regulating plate 12, thereby causing the pressure regulating plate 12 to locally compress the hollow rubber sealing ring 7, thus improving the insulation inside the hollow rubber sealing ring 7. The oil evenly transmits pressure to the hollow rubber sealing ring 7, causing the hollow rubber sealing ring 7 to expand simultaneously, thereby enhancing the sealing effect of the device. This allows the device to be adjusted for sealing later, reducing the impact of aging of the vehicle display screen. In extremely cold weather, the solid sealing ring can expand to compensate for the sealing strength, thus preventing the sealing effect of the display screen from decreasing and causing some moisture to enter the interior of the vehicle display screen. The lower end of the sealing adjustment hexagonal screw 4 is rotatably connected to the pressure adjustment plate 12. Limiting insert plates 10 are fixedly installed on both sides of the lower end of the upper frame body 2 of the vehicle display screen.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The limiting inner plate 10 has three limiting mating holes 11 inside. Installing the limiting inner plate 10 allows the insulating oil to expand the hollow expansion boss 8 when the pressure regulating plate 12 compresses the hollow rubber sealing ring 7, causing the hollow expansion boss 8 to elongate. This, in turn, pushes the limiting locking shaft 9 to move, locking it inside the limiting mating hole 11. This ensures a stable connection between the lower frame body 1 and the upper frame body 2 of the vehicle display screen, achieving internal self-locking and making the device look neater and more aesthetically pleasing. The lower end of the lower frame body 1 and the vehicle display... Limiting bosses 6 are fixedly installed on the upper part of the upper frame body 2. Matching bosses 5 are installed on both sides of the lower frame body 1 of the vehicle display screen. The matching bosses 5 are fixedly connected to the lower frame body 1 of the vehicle display screen. The display body 3 is provided on the inner side of the hollow rubber sealing ring 7. The outer side of the display body 3 is in contact with the matching bosses 5 and the limiting bosses 6. The hollow rubber sealing ring 7 is connected to the lower frame body 1 and the upper frame body 2 of the vehicle display screen through slots. The upper surface of the lower frame body 1 of the vehicle display screen is provided with embedded grooves 13 on both sides. The limiting embedded plate 10 extends into the embedded groove 13.

[0027] Working principle: During use, the operator installs the display screen body 3 inside the hollow rubber sealing ring 7, ensuring the ring completely covers all four sides. Then, the hollow rubber sealing ring 7 is installed from top to bottom inside the lower frame body 1 of the vehicle display screen. Next, the operator places the upper frame body 2 of the vehicle display screen on top of the lower frame body 1, inserting the limiting inner plate 10 into the inner groove 13. Then, the operator controls the upper frame body 2 to move downwards, gradually approaching the lower frame body 1, until it reaches the top of the hollow rubber sealing ring 7, until the lower frame body 1 and the upper frame body 1 are aligned. After the body 2 is fitted together, the operator turns the sealing adjustment hexagonal screw 4, causing the pressure adjustment plate 12 to move. This pressure adjustment plate 12 compresses the upper end of the hollow rubber sealing ring 7, increasing the internal pressure of the hollow rubber sealing ring 7. The insulating oil inside the hollow rubber sealing ring 7 then evenly distributes the pressure to all parts of the hollow rubber sealing ring 7, causing all parts of the hollow rubber sealing ring 7 to expand. This causes the hollow expansion boss 8 to elongate, which in turn pushes the limiting pin 9 to move, locking the limiting pin 9 inside the limiting mating hole 11. This ensures a stable connection between the lower frame body 1 and the upper frame body 2 of the vehicle display screen. Simultaneously, the expansion of all parts of the hollow rubber sealing ring 7 is rapid and even. The device fills the gaps between the main body 3 of the display screen and the lower frame 1 and upper frame 2 of the vehicle display screen, thereby sealing the lower frame 1 and upper frame 2 of the vehicle display screen. As the device is used for an extended period, or when the vehicle owner needs to use the vehicle in extremely cold weather, the operator can tighten the sealing adjustment hexagonal screw 4 as needed to increase the pressure of the pressure adjustment plate 12 on the hollow rubber sealing ring 7, thus improving the device's sealing performance. The installation of the hollow rubber sealing ring 7 and the inclusion of insulating oil inside it facilitates the adjustment of the internal pressure of the hollow rubber sealing ring 7, allowing the insulating oil to evenly distribute the pressure to all parts of the hollow rubber sealing ring 7, causing it to expand simultaneously. The hollow rubber sealing ring 7 seals the device, ensuring its sealing effect. The installation of the sealing adjustment hexagonal screw 4 allows operators to easily control the position of the pressure regulating plate 12, which in turn causes the pressure regulating plate 12 to locally compress the hollow rubber sealing ring 7. This allows the insulating oil inside the hollow rubber sealing ring 7 to evenly distribute pressure, causing the hollow rubber sealing ring 7 to expand simultaneously, thus enhancing the device's sealing effect. This allows for subsequent sealing adjustments, reducing the impact of aging of the vehicle display screen. In extremely cold weather, the solid sealing ring can expand to compensate for the reduced sealing strength, preventing moisture from entering the vehicle display screen and thus ensuring a better seal.Installing the limiting insert plate 10 allows the insulating oil to expand the hollow expansion boss 8 when the pressure regulating plate 12 compresses the hollow rubber sealing ring 7, causing the hollow expansion boss 8 to elongate. This, in turn, pushes the limiting retaining shaft 9 to move, locking it inside the limiting mating hole 11. This ensures a stable connection between the lower frame body 1 and the upper frame body 2 of the vehicle display screen, achieving internal self-locking and resulting in a cleaner and more aesthetically pleasing appearance.
