Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically to a light-leakage-proof display screen frame. Background Technology

[0002] In-vehicle LCD screens are mainly used as display screens. Controlled by the main control device, they can display various images or text, bringing great convenience to people's lives.

[0003] For example, a light leakage prevention and fixing frame for a liquid crystal display screen (publication number: CN222071001U) includes a housing, an internal liquid crystal display screen, a cover plate at the bottom of the housing, a fixing frame fixedly connected to the bottom of the liquid crystal display screen, a reinforcing plate fixedly connected to the bottom of the fixing frame, screws at the four corners of the bottom of the cover plate, a pressure block at the top of the cover plate, a first retaining shell fixedly connected to the bottom of the pressure block, and a second retaining shell slidably connected to the outside of the first retaining shell. This utility model, by using the pressure block, specifically, involves pressing the cover plate after it is installed at the bottom of the housing, fixing the cover plate to the housing with screws, and then pushing the reinforcing plate under the elastic action of a spring, thereby ensuring a tight fit between the liquid crystal display screen and the protective pad. This improves the fixing effect, prevents the liquid crystal display screen from becoming loose, and protects the liquid crystal display screen from damage.

[0004] Based on the search of the aforementioned patents and the findings of existing devices, it is evident that the design of the housing and cover plate in the aforementioned devices does not adequately consider the heat dissipation requirements of the electronic components supporting the display screen. Although the connection structure between the housing and cover plate is robust and can effectively fix the display screen and prevent light leakage, unfortunately, this design lacks a heat dissipation mechanism for the electronic components. The supporting electronic components of the display screen, such as driver chips and power management modules, generate a large amount of heat during operation. Currently, no heat dissipation channels or structures are provided between the housing and cover plate, resulting in the inability to dissipate this heat in a timely and effective manner. Therefore, we need to propose a light leakage-proof display screen bezel. Utility Model Content

[0005] The purpose of this utility model is to provide a light-leakage-proof display screen frame. By setting a heat-conducting component on the bottom cover, the heat-conducting component can conduct heat to the electronic components of the display screen inside the frame, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A light leakage prevention display screen frame includes a frame, a display screen body is installed inside the frame, and a light leakage prevention component is installed on the side of the display screen body. A bottom cover is detachably installed at the bottom of the frame, and a retaining frame is installed on the top of the bottom cover to cooperate with the light leakage prevention component and to abut and limit the bottom of the display screen body. A heat-conducting component for conducting heat to the heating elements inside the frame is installed inside the retaining frame.

[0008] Preferably, the light leakage prevention component includes a spiral-shaped sealing gasket, which is fixedly installed on the inner top of the frame. A spiral-shaped sealing strip is integrally formed on the bottom of the spiral-shaped sealing gasket, and the inner side of the connection between the spiral-shaped sealing gasket and the spiral-shaped sealing strip is respectively attached to the top edge and side wall of the display screen body.

[0009] Preferably, the top of the outer wall of the abutment frame is provided with a groove, and the bottom of the spiral sealing strip is inserted into the inside of the groove.

[0010] Preferably, the heat-conducting component includes a heat-conducting plate, which is fixedly installed on the top surface of the bottom cover. An insulating heat-conducting sheet is fixedly installed on the top of the heat-conducting plate, and several sets of heat dissipation fins are fixedly installed at equal intervals on the bottom of the heat-conducting plate.

[0011] Preferably, the bottom cover has an interface corresponding to several sets of heat dissipation fins, and the bottom of the bottom cover has a heat dissipation groove that connects several sets of interface. The bottoms of several sets of heat dissipation fins extend through several sets of interface to the interior of the heat dissipation groove.

[0012] Preferably, the bottom of the abutting frame is fixedly installed at the top edge of the heat-conducting plate, and two sets of guide blocks are fixedly installed on both outer walls of the abutting frame. The inner wall of the frame is provided with guide grooves corresponding to the guide blocks, and the outer wall of the guide block is slidably connected to the inner wall of the guide groove.

One end of the internal hexagon bolt passes through the countersunk hole and is threaded into the inside of the frame.

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

[0015] This invention, through the setting of a heat-conducting component, utilizes an insulating heat-conducting sheet in conjunction with a heat-conducting plate and heat dissipation fins. The insulating heat-conducting sheet conducts the heat from the electronic components of the display screen to the heat-conducting plate, which then conducts the heat to several sets of equidistantly arranged heat dissipation fins. The heat dissipation fins then dissipate the heat to the bottom of the cover, effectively preventing damage or performance degradation of electrical components due to heat accumulation, thereby improving the safety performance of the entire display screen system.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A light leakage prevention display screen frame includes a frame 1, a display screen body 2 installed inside the frame 1, and a light leakage prevention component 3 installed on the side of the display screen body 2. A bottom cover 4 is detachably installed at the bottom of the frame 1. A retaining frame 5 is installed on the top of the bottom cover 4 to cooperate with the light leakage prevention component 3 and to abut and limit the bottom of the display screen body 2. A heat-conducting component 6 is installed inside the retaining frame 5 to conduct heat to the heat-generating elements inside the frame 1.

[0024] Furthermore, the light leakage prevention component 3 includes a spiral-shaped sealing gasket 31, which is fixedly installed on the inner top of the frame 1. A spiral-shaped sealing strip 32 is integrally formed on the bottom of the spiral-shaped sealing gasket 31. The inner side of the connection between the spiral-shaped sealing gasket 31 and the spiral-shaped sealing strip 32 is respectively attached to the top edge and side wall of the display body 2. The spiral-shaped sealing gasket 31 and the spiral-shaped sealing strip 32 work together to protect the top edge and side wall of the display body 2, while also preventing light leakage.

[0025] Specifically, a groove 8 is formed at the top of the outer wall of the abutting frame 5, and the bottom of the loop-shaped sealing strip 32 is inserted into the inside of the groove 8. The abutting frame 5 is used to abut and limit the bottom of the display screen main body 2, and cooperate with the light leakage prevention component 3 to play a role in limiting and protecting the display screen main body 2, and at the same time, there is no light leakage space for the display screen main body 2.

[0026] Further, the heat conduction component 6 includes a heat conduction plate 61, the heat conduction plate 61 is fixedly installed on the top surface of the bottom cover 4, an insulating heat conduction sheet 62 is fixedly installed on the top of the heat conduction plate 61, and a plurality of groups of heat dissipation fins 63 are fixedly installed at equal intervals on the bottom of the heat conduction plate 61. The insulating heat conduction sheet 62 is attached to the bottom of the electronic components supporting the display screen (such as a circuit board, not shown in the figure). The heat generated by the heat dissipation of the electronic components supporting the display screen is conducted to the heat conduction plate 61 through the insulating heat conduction sheet 62, and the heat conduction plate 61 conducts the heat to a plurality of groups of heat dissipation fins 63 arranged at equal intervals.

[0027] Specifically, insertion openings 7 corresponding to the plurality of groups of heat dissipation fins 63 are formed on the bottom cover 4, and a heat dissipation groove 11 communicating with the plurality of groups of insertion openings 7 is formed at the bottom of the bottom cover 4. The bottoms of the plurality of groups of heat dissipation fins 63 respectively pass through the plurality of groups of insertion openings 7 and extend into the inside of the heat dissipation groove 11. The heat is conducted and dissipated to the bottom of the bottom cover 4 through the heat dissipation fins 63, which can effectively avoid damage or performance degradation of electrical components caused by heat accumulation.

[0028] Specifically, the bottom of the abutting frame 5 is fixedly installed at the top edge of the heat conduction plate 61. Two groups of guide blocks 9 are fixedly installed on the outer walls of both sides of the abutting frame 5. Guide grooves 10 corresponding to the guide blocks 9 are formed on the inner wall of the frame body 1. The outer wall of the guide block 9 is slidably connected to the inner wall of the guide groove 10, which is convenient for guiding and limiting the installation of the bottom cover 4 by the cooperation of the guide block 9 and the guide groove 10.

[0029] Specifically, four sets of countersunk holes are symmetrically formed at the bottom of the bottom cover 4. Inner hexagon bolts 12 are arranged inside the four sets of countersunk holes. One end of the inner hexagon bolt 12 passes through the countersunk hole and is threadedly connected to the inside of the frame body 1, which is convenient for disassembling and assembling the bottom cover 4 through the inner hexagon bolts 12.

[0030] Working Principle: In use, this utility model involves installing the display body 2 inside the frame 1, with the top and sides of the display body 2 fitting against the inner side of the connection between the U-shaped sealing gasket 31 and the U-shaped sealing strip 32 in the anti-leakage light assembly. The bottom cover 4 is then installed at the bottom of the frame 1 using hexagonal bolts 12, so that the top of the abutting frame 5 abuts against the bottom edge of the display body 2. The U-shaped sealing strip 32 is inserted into the groove 8 at the top of the abutting frame 5, thus limiting and fixing the display body 2 while preventing light leakage. Through the heat-conducting component 6, the insulating heat-conducting sheet 62, in conjunction with the heat-conducting plate 61 and heat dissipation fins 63, conducts heat from the electronic components of the display to the heat-conducting plate 61. The heat-conducting plate 61 then conducts the heat to several sets of equidistantly arranged heat dissipation fins 63, which then dissipate the heat to the bottom of the bottom cover 4. This effectively prevents damage or performance degradation of electrical components due to heat accumulation, thereby improving the safety performance of the entire display system.
