For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0036] Please refer to Figures 1 to 4 In the first embodiment of the present application, a glue iron 10 for preventing light leakage of camera blind hole is provided, which comprises an iron frame 11, an iron frame round hole 12 for accommodating a camera module is formed on the iron frame 11, an iron frame round pipe 13 extends on the iron frame round hole 12, and an injection glue sticking part 14 for sticking light shielding glue is arranged on one end of the iron frame round pipe 13 away from the iron frame round hole 12.

[0037] It can be known that the glue iron 10 is provided with the iron frame round pipe 13 on the iron frame round hole 12 of the iron frame 11, one end of the iron frame round pipe 13 away from the iron frame round hole 12 is provided with the injection glue sticking part 14 for sticking light shielding glue, the thickness of the pipe wall of the iron frame round pipe 13 is increased, and then the sticking area and the supporting strength of the light shielding glue are effectively increased, the light shielding glue is effectively prevented from being separated at the position of the iron frame round pipe 13, the light leakage of the backlight source 1 at the camera blind hole is avoided, and the overall reliability of product assembly is improved.

[0038] Please refer to Figures 3 to 7In some embodiments, the iron frame round pipe 13 comprises a round pipe body 131, a top end surface 132 and an outer surface 133; the inner diameter of the round pipe body 131 is the same as the inner diameter of the iron frame round hole 12, which ensures the installation of the camera; the top end surface 132 is arranged at the end of the round pipe body 131 away from the iron frame round hole 12, which provides a flat bonding interface for the light shielding glue to enhance the bonding stability; the outer surface 133 is the surface of the round pipe body 131 away from the axis, which further increases the bondable area of the light shielding glue, thereby improving the fixing strength and light shielding effect of the light shielding glue; the glue injection and bonding part 14 covers the top end surface 132 and the outer surface 133, forming an overall cladding fixing structure, which greatly increases the bonding area of the light shielding glue by covering the top end surface 132 and the outer surface 133 at the same time, not only enhancing the bonding strength of the light shielding glue and the iron frame round pipe 13, but also enabling the light shielding glue to maintain firm adhesion in complex environments such as high temperature and high humidity, which is suitable for scenes with high requirements for light shielding performance and reliability; or, the glue injection and bonding part 14 covers the outer surface 133 and is flush with the top end surface 132, thereby optimizing the fixing method and glue injection process of the light shielding glue; by arranging the glue injection and bonding part 14 only on the outer surface 133 and flush with the top end surface 132, the light shielding glue can be adhered to the outer surface 133 and the bottom end surface at the same time, reducing the amount of glue on the top end surface 132, which on the one hand reduces material costs and on the other hand ensures the stability and light shielding effect of the light shielding glue in critical positions.

[0039] In some embodiments, the area where the glue injection and bonding part 14 is located on the outer surface 133 is uniformly provided with a plurality of weight reduction notches 134 in the circumferential direction. That is, while ensuring the improvement of the light shielding glue bonding effect, the weight reduction notches 134 arranged on the outer surface 133 of the cylinder reduce the amount of material used, thereby reducing the weight of the entire glue iron 10, which is beneficial to the lightness and thinness of the backlight 1; the plurality of weight reduction notches 134 are symmetrically distributed on the cylinder, avoiding stress concentration caused by material weight reduction.

[0040] Further, the geometric shape of the plurality of weight reduction notches 134 is arranged as regular arc grooves, which naturally transition with the curved surface structure of the cylinder, thereby avoiding damage to the light shielding glue caused by sharp edges. The arc length of each weight reduction notch 134 is arranged to be 10°-30° of the circumference, and the depth is 10%-30% of the wall thickness of the cylinder, thereby ensuring sufficient mechanical strength while reducing weight. At the same time, the number of weight reduction notches 134 is 3-8, which are uniformly distributed in the circumferential direction, and the spacing between each weight reduction notch 134 is equal, so as to ensure the structural symmetry and avoid assembly deviation or stress concentration caused by imbalance.

[0041] In some embodiments, the glue injection and adhesion part 14 is arranged on the outer surface 133 in a flat and continuous manner. By arranging the glue injection and adhesion part 14 in a flat and continuous manner without steps, grooves or other surface irregularities, the flat and continuous surface provides a uniform and smooth adhesion interface, so that the light shielding glue can be uniformly distributed on the surface of the glue injection and adhesion part 14, avoiding the problems of glue accumulation or insufficient adhesion caused by surface irregularities, thereby significantly improving the initial adhesion strength and long-term stability of the light shielding glue.

[0042] For reference Figure 8 In some embodiments, the glue injection and adhesion part 14 covers the entire outer surface 133 in the axial direction, thereby effectively improving the connection strength of the glue injection and adhesion part 14 and the outer surface 133.

[0043] In some embodiments, a plurality of glue injection fixing grooves 135 are arranged around the outer surface 133, which are used to improve the connection strength of the glue injection and adhesion part 14 and the circular tube body 131, thereby effectively ensuring the connection strength of the glue injection and adhesion part 14 and the iron frame circular tube 13.

[0044] In some embodiments, the wall thickness of the radial section of the iron frame circular tube 13 is 0.25-0.45mm, thereby effectively ensuring that the light shielding glue has sufficient adhesion area.

[0045] For reference Figure 9 The second embodiment of the present application also provides a backlight source 1 comprising the glue iron 10 provided in the first embodiment of the present application, thereby effectively ensuring the light shielding effect at the camera blind hole 20 and avoiding the light leakage defect at the camera blind hole 20. For details, please refer to the first embodiment of the present application.

[0046] The third embodiment of the present application also provides a display device comprising the backlight source 1 provided in the second embodiment of the present application, thereby effectively ensuring the light shielding effect at the camera blind hole and avoiding the light leakage defect at the camera blind hole.

[0047] The fourth embodiment of the present application also provides a smart mobile terminal comprising the backlight source 1 provided in the second embodiment of the present application, thereby effectively ensuring the light shielding effect at the camera blind hole 20 and avoiding the light leakage defect at the camera blind hole 20, thereby ensuring the camera shooting effect of the smart mobile terminal.
