[0030] The following will be combined with Figure 2 to detail a reinforced and optimized structure of a TV backplane rib involved in the embodiments of the present application. It should be noted that the following embodiments are only used to explain the present application and do not constitute a limitation to the present application.

[0031] Embodiment 1:

[0032] As Figure 1-2 shown, a reinforced and optimized structure of a TV backplane rib includes: a backplane 1 made of SECC or SGCC. The backplane usually has a rib strengthening structure, and there are height differences in single ribs or height differences in cross ribs.

[0033] That is, lower ribs 11 and higher ribs 12 are provided on the backplane 1, and the height of the lower ribs 11 is lower than the height of the higher ribs 12. The lower ribs 11 and the higher ribs 12 are connected by a connection structure 13. The connection draft angle of the connection structure between the lower ribs and the higher ribs is between 80° and 85°. In the reinforced and optimized structure of the TV backplane rib of the present invention, by reasonably setting the connection structure between the lower ribs and the higher ribs, not only is the rigidity of the backplane not reduced due to the low ribs, but at the same time, the stress concentration phenomenon at the connection of the high and low ribs is alleviated and the strength is increased.

[0034] In some embodiments, a single rib or a cross rib is formed between the lower rib 11 and the higher rib 12. Wherein, the upper surface of the connecting structure 13 is an inclined surface, and the high end is close to the side of the higher rib 12. The connecting structure 13 is integrally formed with the lower rib 11, and a fillet 14 with a radius of R20 - R50 is provided at the transition between the connecting structure 13 and the lower rib 11. The connecting structure 13 is integrally formed with the higher rib 12, and a fillet 14 with a radius of R20 - R50 is provided at the transition between the connecting structure 13 and the higher rib 12. The inclined surface of the connecting structure 13 and the planes of the lower rib 11 and the higher rib 12 are transitioned by a fillet surface, a die fillet, which increases the overall and local rigid strength structure of the backplane. Its main functions are to enhance the rigidity of the backplane, reduce the stress concentration at the turning points of the lower rib and the higher rib, and reduce the die angle to enhance the service life of the die.

[0035] In some embodiments, when the lower rib 11 and the higher rib 12 are cross ribs, the included angle between the lower rib 11 and the higher rib 12 is 30° - 150°. The connecting draft angle of the connecting structure between the lower rib and the higher rib is between 80° - 85°.

[0036] Figure 3 , Figure 5 , Figure 7 It shows the maximum deformation at the center point under the same load, which are 0.313 mm, 0.308 mm, and 0.288 mm respectively. The deformation reduction gains are that the deformation is reduced by 1.6% when the draft angle is 60° compared with when the draft angle is 30°; the deformation reduction gains are that the deformation is reduced by 8% when the draft angle is 85° compared with when the draft angle is 30°, and the gain is obvious.

[0037] Figure 4 , Figure 6 , Figure 8 It shows the stress at the stress concentration point of the connecting corner under the same load, which are 32.41 MPa, 28.98 MPa, and 11.62 MPa respectively. The stress reduction gains are that the stress is reduced by 10.6% when the draft angle is 60° compared with when the draft angle is 30°; the deformation reduction gains are that the stress is reduced by 64% when the draft angle is 85° compared with when the draft angle is 30°, and the gain is obvious.

[0038] The rib reinforcement and optimization structure of the TV backplane of the present utility model reasonably sets a connecting structure between the lower rib and the higher rib, which not only avoids the reduction of the rigidity of the backplane due to the low ribs, but also relieves the stress concentration phenomenon at the connection of the high and low ribs and increases the strength.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
