[0003] Announcement No. CN218068506U: A backlight structure with high heat dissipation. This utility model relates to the field of display screen technology. The backlight structure includes a connecting frame with a groove inside. A light source board is adhered to the inside of the groove via an adhesive pad. A heat dissipation mechanism, including an air inlet, is provided inside the connecting frame. A filter is fixed inside the air inlet by the mutual adhesion between the connecting block and the connecting frame. A fan operates, using the air inlet to blow air into the groove to dissipate heat from the light source board, and the air is discharged through the fan and the internal groove. This significantly improves the heat dissipation performance of the entire structure and ensures operational safety. A positioning groove connects the connecting frame to adjacent components. A spring-loaded locking head slides along a groove inside the opening, thus securing the connection between adjacent components and ensuring connection stability, preventing damage or delamination.

[0004] This method effectively dissipates heat from the light source board using a fan, but the fan requires a motor to drive it. The installation of the motor, due to its own size, requires a lot of space, which results in the backlight becoming thicker. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] This utility model provides, for example Figure 1-6 The illustrated high-efficiency heat dissipation mechanism for a backlight display includes a mounting frame 3, inside which are disposed a liquid crystal display 1 for heat dissipation and a backlight module 2, and further includes:

[0030] Heat dissipation component 4, which includes fan 41, is used for heat dissipation of backlight module 2;

[0031] The air intake mechanism includes an air intake plate 5 and an air intake groove 6, the air intake groove 6 being used to blow airflow toward the air intake plate 5;

[0032] Connector 7 is used to connect the air intake plate 5 and the heat dissipation assembly 4.

[0033] Specifically, both the LCD screen 1 and the backlight module 2 are fitted inside the mounting frame 3.

[0034] Furthermore, the LCD screen 1 and the backlight module 2 are existing display screens and backlight modules. The backlight module 2 emits a light source to image the LCD screen 1. The mounting frame 3 has a plastic frame inside, which is fitted onto the outer wall of the LCD screen 1 and the backlight module 2. The plastic frame and the mounting frame 3 are snapped together by a buckle, thereby installing the LCD screen 1 and the backlight module 2 inside the mounting frame 3, which is a common method in the prior art.

[0035] Specifically, the air intake slot 6 includes an intake section 61, a compression section 62, and a diffuser section 63. The intake section 61, compression section 62, and diffuser section 63 are sequentially interconnected. The air intake slot 6 is obliquely opened on the front of the intake plate 5. The intake section 61 is used for airflow input and to transmit airflow to the compression section 62. The compression section 62 is used to compress and accelerate the airflow transmitted by the intake section 61 and transmit it to the diffuser section 63. The diffuser section 63 releases the accelerated and compressed airflow and blows it toward the fan 41.

[0036] Furthermore, the entire device is generally placed in a ventilated area, and the outer wall of the frame is provided with heat dissipation holes. Therefore, the air intake slots 6 and the fan 41 are used to assist the heat dissipation holes in heat dissipation. The air intake slots 6 are used to accelerate the airflow. Multiple air intake slots 6 are provided, and the multiple air intake slots 6 are arranged in a ring. The angle of the air intake slots 6 is all in the same direction, corresponding to the direction of the fan blades of the fan 41. Thus, when the air blows into the air intake section 61, the air will be gradually compressed inside the air intake section 61. It will be completely compressed in the compression section 62, accelerating the airflow. Finally, the diffusion section 63 sprays the accelerated air towards the fan blades of the fan 41. Thus, the fan 41 is driven to rotate by the spray from the multiple air intake slots 6, which dissipates heat from the backlight module 2. In conjunction with the heat dissipation holes, the heat dissipation effect is further enhanced, while saving the space occupied by the motor.

[0037] Specifically, the front of the fan 41 is provided with a mounting bracket 42 for mounting the fan 41. The mounting bracket 42 is fitted with a fixing frame 43 for fixing the mounting bracket 42. The front of the fixing frame 43 is provided with fixing bolts 44 for fixing the mounting bracket 42 and the mounting frame 3. The front of the fixing frame 43 is provided with a connecting groove 8 for the connector 7 to be inserted. The horizontal cross section of the connecting groove 8 is L-shaped.

[0038] Furthermore, a round rod is inserted into the middle of the fan 41. The outer wall of the round rod is smooth, so as not to affect the rotation of the fan 41. A threaded section is opened at the end of the round rod away from the mounting bracket 42. A nut is threaded on the outer wall of the threaded section. The nut is used to prevent the fan 41 from slipping out of the round rod. The end of the round rod is bonded and fixed to the mounting bracket 42. The part of the mounting bracket 42 that contacts the fixing frame 43 is bonded and fixed. The mounting frame 3 and the fixing frame 43 are fixed by bolts. The size of the connecting groove 8 is 1.1 times the size of the connecting piece 7. Two connecting grooves 8 are opened, respectively symmetrically opened on both sides of the front of the fixing frame 43.

[0039] Specifically, the connector 7 includes an insert block 71 and a locking block 72. The front of the insert block 71 is fixedly connected to the back of the air intake plate 5. The insert block 71 has a cavity for installing the locking block 72. One side of the inner wall of the cavity has an insertion hole. The locking block 72 is inserted into the insertion hole. One end of the locking block 72 is fixedly connected to a baffle 73. One side of the baffle 73 is provided with an elastic block 74 for pushing the baffle 73.

[0040] Furthermore, the number of connectors 7 corresponds to the number of connecting slots 8. Connectors 7 are used for quick connection and disassembly of the air intake plate 5 and the fixing frame 43. The insert block 71 and the locking block 72 form an L-shaped structure corresponding to the connecting slot 8. Both end slots of the connecting slot 8 penetrate the outer wall of the fixing frame 43, allowing the insert block 71 to be inserted into the connecting slot 8. At the same time, the locking block 72 inserted into the connecting slot 8 can be pressed through the other end slot to unlock the insert block 71. The part of the insert block 71 that contacts the air intake plate 5 is fixed by adhesive. The size of the insertion hole is 1.02 times the size of the locking block 72, the size of the baffle 73 is 1.1 times the size of the insertion hole, the elastic block 74 is an elastic rubber block, both the baffle 73 and the elastic block 74 are in the cavity, the elastic block 74 is always in a compressed state in the cavity, by pressing the locking block 72, the insert 71 is inserted into the interior of the connecting groove 8, when the locking block 72 encounters the transverse port, it pops out under the elastic action of the elastic block 74, thereby fixing the insert 71 in the connecting groove 8, and completing the installation of the air intake plate 5.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
