[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] This application proposes a backlight plate positioning structure, please refer to Figure 1 , Figure 2 and Figure 3 , including: a circular stopper 11, a metal plate 10 and a positioning assembly 20. The positioning assembly 20 includes a base 21 and a positioning column 22. The base 21 is arranged at the bottom of the positioning column 22. The diameter of the base 21 is larger than the diameter of the positioning column 22. The surface of the metal plate 10 extends the enclosure 12 in the thickness direction. The circular stopper 11 covers the enclosure 12 to form an installation cavity. The circular stopper 11 is provided with a through hole connected to the installation cavity. The base 21 is installed in the installation cavity. The positioning column 22 extends to the outside through the through hole for positioning for subsequent assembly. Other parts to be assembled are sleeved on the positioning column 22. The positioning assembly 20 is fixed on the metal plate 10. The base 21 includes a bottom surface and an opposite top surface. The bottom surface of the base 21 is fixed on the metal plate 10, and the top surface of the base 21 is connected to the positioning column 22. Since the thickness of the metal plate 10 is relatively small, the metal plate 10 is easily deformed due to the force of the positioning assembly 20. A circular blocking member 11 and an enclosure 12 limiting base 21 are provided at the connection between the positioning column 22 and the metal plate 10, which not only increases the fixing area of ​​the positioning assembly 20 and the metal plate 10, but also enhances the ability of the metal plate 10 to resist deformation of the positioning assembly 20, thereby improving the delivery quality of the backlight panel. The height of the installation cavity is consistent with the height of the bottom plate 211, so that the bottom plate 211 is tightly limited to the bottom plate 211 in the installation cavity to prevent the bottom plate 211 from shaking in the installation cavity. Preferably, the metal plate 10 is a rectangular parallelepiped structure.

[0025] In one embodiment, the ratio of the height of the base 21 to the height of the positioning assembly 20 is 0.25, that is, the ratio of the height of the positioning column 22 to the height of the base 21 is 3, so that the positioning column 22 can be inserted into more components, and the material on the base 21 is saved, thereby reducing costs. Specifically, the base 21 includes a bottom plate 211 and a base 212. The bottom plate 211 and the base 212 are fixedly sleeved on one end of the positioning column 22, and the bottom plate 211 is set in the installation cavity. The bottom plate 211 and the base 212 jointly clamp the annular blocking member 11, so that the base 21 is more firmly fixed on the metal plate 10, so that the metal plate 10 is less likely to deform. For further information, please refer to Figure 3 A wavy clamp is provided on the side of the bottom plate 211, and a clamping sleeve cooperating with the clamp is provided on the inner wall of the mounting groove, so that the positioning assembly 20 and the metal plate 10 do not rotate relative to each other, thereby preventing the components sleeved on the positioning column 22 from rotating and causing undesirable misalignment.

[0026] In another embodiment, see Figure 2, one end of the positioning column 22 away from the base 21 is set to be hemispherical, and the parts to be assembled are smoothly inserted from the top of the positioning column 22, thereby improving the work efficiency of assembly. Furthermore, the positioning column 22 is cylindrical, and the parts inserted into the positioning column 22 are rotated to adjust the position, thereby improving the assembly accuracy of the parts. Further, the metal plate 10 is provided with two positioning components 20 on the same side, and two enclosures 12 are extended from the surface of the metal plate 10 in the thickness direction, and two annular blocking members 11 are respectively covered on the two enclosures 12 to form two installation cavities, and the annular blocking members 11 are provided with through holes connected to the installation cavities, and the base 21 is installed in the installation cavity, and the positioning column 22 extends to the outside through the through holes to further position the parts to be assembled, so that the parts to be assembled are accurately set on the metal plate 10. In addition, the metal plate 10 is an iron plate, and buckles are provided on the iron plate to facilitate the connection with the backlight.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
