Description

Technical Field

[0001] The utility model relates to the field of lamps, in particular to a small-volume anti-collision column Background Art

[0002] The existing backlight module includes a frame, a light guide plate, a diffuser plate and a backlight source. The backlight source generally includes a substrate and LED lamp beads arranged on the substrate. When installing the light guide plate and the diffuser plate, it is easy to hit the LED lamp beads, thereby easily damaging the LED lamp beads. Therefore, an anti-collision column is arranged on the substrate, and the height of the anti-collision column is higher than the height of the LED lamp beads (so as to play a role of pre-stress).

[0003] However, the existing anti-collision column has a complex structure and blocks a lot of light from the LED lamp beads, which affects the light output of the LED lamp beads.

[0004] The anti-collision column generally includes a metal bracket and an elastic seat wrapped around the bracket, so the combination of the two is related to the safety of the LED lamp beads (such as the falling off of the elastic seat).

[0005] The metal bracket is mainly used to facilitate the welding of the anti-collision column. The existing metal bracket is generally suitable for the overall height of the elastic seat, so that the combination of the metal bracket and the elastic seat is more stable (avoiding the problem of separation after collision).

[0006] However, in a smaller-sized anti-collision column, if the metal bracket is too high, the cushioning effect of the elastic seat will be reduced; when the metal bracket is too short, the bonding degree between the elastic seat and the bracket will be reduced, and the welding stability will also be reduced. Utility Model Content

[0007] The main purpose of the utility model is to provide a small-volume anti-collision column, aiming to simplify the production and reduce the cost by improving the structure of the bracket, and the elastic seat after molding has a more stable combination and is convenient to weld.

[0008] To achieve the above purpose, the utility model provides a small-volume anti-collision column, comprising:

[0009] A bracket, wherein a through hole is provided in the middle of the bracket, and a supporting portion of the bracket extends upward from the through hole;

[0010] The elastic seat is formed on the upper wall of the bracket, and the elastic seat extends toward the inner wall of the supporting part to form a limiting wall.

[0011] In the actual design, a through hole is directly formed in the middle of the bracket and the support part is extended integrally, so that the integrity of the bracket is better, and the bonding between the bracket and the elastic seat can be strengthened. The structure is simple, and the through hole is used as an injection hole to mold the plastic between the outer wall and the inner wall of the support part through the through hole, thereby improving the bonding between the elastic seat and the bracket and ensuring the stability after welding (avoiding the detachment of the elastic seat). The height of the elastic seat reaches a predetermined value, which can have a better buffering effect. BRIEF DESCRIPTION OF THE DRAWINGS
