Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a lamp board connection structure and a display device. Background Technology

[0002] In the assembly process of existing display modules, the connection between the lamp board and the base shell is typically achieved using screw fastening. Screw mounting posts are welded to the back of the lamp board, and screws pass through the base shell to secure it to the mounting posts, thus connecting the lamp board and the base shell. However, in actual production and use, it has been found that uneven cooling temperatures are prone to occur at the weld joints of the mounting posts when welding them to the back of the lamp board. This temperature difference can cause the mounting posts to shift or tilt abnormally during cooling. When the lamp board and base shell are subsequently assembled, this abnormal shift or tilting of the mounting posts leads to stress concentration at the connection between the lamp board and the base shell. With increased usage time, under the influence of stress concentration, the connection between the mounting posts and the lamp board is highly susceptible to breakage, severely affecting the structural stability and lifespan of the display module. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a lamp panel connection structure and display device to solve the problem that the mounting columns of the current lamp panels have the risk of abnormal detachment.

[0033] Example 1

[0034] Combination Figures 1 to 7 As shown, the lamp panel connection structure of this utility model is schematically illustrated, including a first component 10 and a second component 20.

[0035] like Figure 6 and Figure 7 The first component 10 has a sleeve 10c protruding from it. The sleeve 10c has a mounting hole 11. The inner wall of the mounting hole 11 has a clearance groove 111 and a limiting part 112 arranged alternately along its circumference. In this embodiment, there are two clearance grooves 111 and two limiting parts 112. Therefore, the openings of the two clearance grooves 111 are arranged opposite to each other.

[0036] The second component 20 is provided with a first limiting protrusion 21, preferably two of them. As the second component 20 passes through the mounting hole 11 of the first component 10, the first limiting protrusion 21 passes through the relief groove 111. Then, the second component 20 is rotated so that the first limiting protrusion 21 and the relief groove 111 are misaligned, and the first limiting protrusion 21 and the limiting part 112 are opposite to each other. At this time, the limiting part 112 and the first limiting protrusion 21 cooperate to prevent the first component 10 and the second component 20 from separating.

[0037] Combination Figure 4 and Figure 5 A filler portion 30 is provided between the first component 10 and the second component 20. The filler portion 30 is preferably formed by the solidification of an adhesive filler. It connects the first component 10 and the second component 20 by applying the adhesive filler into the mounting hole 11 and then connecting the first component 10 and the second component 20, ensuring the filler fills the gap between them. Before the filler solidifies, the second component 20 is placed on the first component 10, and its position is maintained by a tooling fixture to ensure it does not shift or tilt until the filler solidifies, thus guaranteeing the installation accuracy of the second component 20. The solidified viscous filler forms a filling portion 30, which can prevent the first component 10 and the second component 20 from rotating relative to each other. The setting of the limiting portion 112 and the first limiting protrusion 21 can also prevent the filling portion 30 from being directly torn by tensile force. That is, when an external force is applied to the first component 10 and the second component 20 to force the first component 10 and the second component 20 to separate, the limiting portion 112 and the first limiting protrusion 21 bear the external force, and the filling portion 30 is used to prevent the first component 10 and the second component 20 from rotating relative to each other.

[0038] The second component 20 is provided with a second limiting protrusion 22, which is staggered from the first limiting protrusion 21 and their extension directions are parallel to each other. During the process of the second component 20 passing through the mounting hole 11 of the first component 10, after the first limiting protrusion 21 passes through the relief groove 111, the second limiting protrusion 22 abuts against the upper surface of the sleeve 10c and limits the first component 10 and the second component 20 to prevent the first component 10 and the second component 20 from moving excessively. At this time, the first component 10 and the second component 20 can be rotated to make the first limiting protrusion 21 and the relief groove 111 staggered. In this embodiment, the second component 20 is a rotating body structure. The first limiting protrusion 21 and the second limiting protrusion 22 are both arranged along the circumference of the second component 20. After the first limiting protrusion 21 passes through the relief groove 111, the second limiting protrusion 22 abuts against the upper surface of the sleeve 10c. During the rotation of the first component 10 and the second component 20, the second limiting protrusion 22 slides relative to the upper surface of the sleeve 10c.

[0039] The outer diameter of the second limiting protrusion 22 is larger than the inner diameter of the mounting hole 11. The end face of the second limiting protrusion 22 is opposite to the upper surface of the sleeve 10c. The first limiting protrusion 21 cooperates with the limiting part 112 to prevent the first component 10 and the second component 20 from separating. The second limiting protrusion 22 cooperates with the upper surface of the sleeve 10c to prevent the first component 10 from continuing to penetrate into the mounting hole 11, thus avoiding the end of the first component 10 accidentally piercing the lamp plate 40 connected to the second component 20. The outer edge perimeter of the first limiting protrusion 21 is smaller than the outer edge perimeter of the second limiting protrusion 22. This structure allows for a larger connection area between the second limiting protrusion 22 and the upper surface of the sleeve 10c, resulting in a stronger load-bearing capacity.

[0040] To improve the bonding stability of the first component 10 and the second component 20, a filling part 30 is provided between the end face of the second limiting protrusion 22 and the upper surface of the sleeve 10c.

[0041] Furthermore, combined Figures 1 to 5As shown, the first component 10 has a front side 10a and a back side 10b. The back side 10b of the first component 10 has a receiving cavity 12, the opening of which is opposite to the lamp panel 40. The receiving cavity 12 extends into the interior of the sleeve 10c and communicates with the mounting hole 11. A first limiting protrusion 21 is located inside the receiving cavity 12. A filling part 30 is provided inside the receiving cavity 12, and the adhesive filler inside the receiving cavity 12 can bond to the lamp panel 40 through the opening of the receiving cavity 12. A gap exists between the end face of the second component 20 located inside the receiving cavity 12 and the plane of the back side 10b of the first component 10. A filling part 30 is provided in the gap. This filling part 30 not only serves to bond the end face of the second component 20 to the lamp panel 40, but also acts as a buffer between the end face of the second component 20 and the lamp panel 40 to prevent the second component 20 from puncturing the lamp panel 40 due to external impact.

[0042] Example 2

[0043] The difference between this embodiment and Embodiment 1 is that the second component 20 has a clearance hole 23. When the second component 20 is made of a transparent material, the clearance hole 23 can be used to insert a UV lamp, which can accelerate the curing of the existing adhesive filler and form the filling part 30. In other optional embodiments, the clearance hole 23 has an internal thread, which can be connected with fasteners such as screws or bolts.

[0044] Example 3

[0045] Combination Figure 8 and Figure 9 As shown, this embodiment discloses a display device 100, including a lamp board 40, a bottom shell 50, and a lamp board connection structure as described above. The lamp board connection structure is welded or bonded to the lamp board 40, so that the first component 10 is fixed on the lamp board 40, and the second component 20 is connected to the first component 10 through the filling part 30. Screws are inserted through the bottom shell 50 and threaded to the second component 20, so that the bottom shell 50 and the lamp board 40 are connected through the lamp board connection structure.

[0046] In summary, the inner wall surface of the mounting hole 11 on the sleeve 10c of the first component 10 is provided with a clearance groove 111 and a limiting part 112 arranged alternately along its circumference. During the process of the second component 20 passing through the mounting hole 11, the first limiting protrusion 21 on the second component 20 passes through the clearance groove 111. The second component 20 is rotated so that the first limiting protrusion 21 and the clearance groove 111 are misaligned, and the first limiting protrusion 21 and the limiting part 112 are arranged opposite to each other. The limiting part 112 cooperates with the first limiting protrusion 21 and prevents the first component 10 and the second component 20 from separating. The filling part 30 between the first component 10 and the second component 20 can achieve an adhesive effect. This structure can eliminate the influence of the high temperature generated during welding on the installation accuracy and installation stability, and improve the structural stability and service life of the product.
