[0036] Embodiment 1: A backlight source with a heat dissipation mechanism, see Figures 1 to 5 , including a light guide plate 1, a light source module 2 is arranged at the front end of the light guide plate 1, and also includes a connecting structure 3; the connecting structure 3 is connected to the light guide plate 1;

[0037] The connection structure 3 includes a back frame 301 and a back plate 302; the back frame 301 is embedded and matched with the light guide plate 1; the back plate 302 is fixed on the back side of the back frame 301; wherein, the four sides of the light guide plate 1 are respectively arranged with heat dissipation abutment plates 201, and the four sides of the back frame 301 are respectively opened with through holes 3011, and the heat dissipation abutment plates 201 abut and match with the through holes 3011.

[0038] The utility model has the advantage of facilitating the installation and positioning of the light guide plate 1 by providing a back frame 301, a back plate 302, a heat dissipation abutment sheet 201 and a perforation 3011, while at the same time, the heat generated by the heat dissipation abutment sheet 201 is discharged from the perforation 3011 to enhance the heat dissipation, thereby solving the problem that the heat generated by the backlight source is also accumulated in a small space and the heat dissipation effect is not ideal if it is only relying on itself.

[0039] Specifically, the heat dissipation abutting piece 201 adopts an arc-shaped structure design, and the inner side of the perforation 3011 is set as an abutting groove 3011-2, and the arched end of the heat dissipation abutting piece 201 abuts and cooperates with the abutting groove 3011-2. The arc-shaped heat dissipation abutting piece 201 and the abutting groove 3011-2 abut and position more smoothly.

[0040] Furthermore, the outer side of the through hole 3011 is configured as a heat dissipation groove 3011 - 1 , and the heat dissipation groove 3011 - 1 is connected with the abutting groove 3011 - 2 , and the heat dissipation groove 3011 - 1 dissipates heat outwards.

[0041] Furthermore, gaps are left between the four sides of the light guide plate 1 and the four sides of the back frame 301 , which helps to dissipate heat and facilitates the bending of the heat dissipation abutting sheet 201 when it is squeezed.

[0042] It is worth noting that the connection structure 3 also includes an insert block 303 and a connection block 305;

[0043] The insert block 303 is inserted into the groove A3012 and the groove B3013 opened at the long side end of the back frame 301; wherein, a rubber pad 304 is fixedly provided at the inner end of the insert block 303, and the rubber pad 304 is abutted against the outer wall of the back frame 301; the connecting block 305 is fixedly arranged at the outer end of the insert block 303; wherein, the connecting block 305 is embedded and matched with the groove A3012; wherein, the two ends of the connecting block 305 are respectively connected to the two ends of the connection between the groove A3012 and the groove B3013 by screws 306, and the screws 306 pass through the connecting block 305 and are screwed into the threaded holes at the connection between the groove A3012 and the groove B3013.

[0044] The utility model has the advantage of positioning the light guide plate 1 after the light guide plate 1 is embedded in the back frame 301 by arranging the insert block 303, the connecting block 305, the groove A3012, the groove B3013 and the screw 306, so as to keep the light guide plate 1 embedded stably.

[0045] It is worth noting that the length of the groove A3012 is greater than the length of the groove B3013, and the connecting block 305 can be stably located in the groove A3012.

[0046] Working principle: When the device of the utility model is used, the light guide plate 1 is embedded in the back frame 301, and the arc-shaped heat dissipation abutting sheet 201 is squeezed and bent by the inner wall of the back frame 301 until the light guide plate 1 is completely inserted into the back frame 301. The arched end of the arc-shaped heat dissipation abutting sheet 201 corresponds to the abutting groove 3011-2 and rebounds to engage with the abutting groove 3011-2. The plug block 303 is correspondingly inserted into the groove A3012 and the groove B3013 until the connecting block 305 is embedded in the groove A3012. The screw 306 passes through the connecting block 305 and is screwed into the threaded hole at the connection between the groove A3012 and the groove B3013. At this time, the rubber pad 304 abuts against the light guide plate 1 to further position the light guide plate 1. The heat generated by the heat dissipation abutting sheet 201 is discharged from the perforation 3011.
