Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED display technology, and more specifically, to an aging test fixture for display modules. Background Technology
[0002] LED display modules typically undergo aging tests during manufacturing to ensure product quality. During aging tests, the modules are usually mounted on an aging rack, the dimensions of which are usually matched to the specifications of the LED display modules to ensure the smooth execution of the aging test.
[0003] However, with the increasing diversification of LED products and the continuous launch of new LED display products, these new products differ from conventional modules in various aspects. During aging tests, new products require modules to be assembled into the cabinet before powering on and aging can begin. Completely assembled modules cannot be aged on the existing aging racks of conventional modules. Furthermore, because the dimensions of individual modules in new products differ from those in conventional modules, they cannot be adapted to the spacing of the aging racks. For example, the module size of a new product is 250*250mm (1:1), while the size of a conventional module is 320*160mm (2:1). Conventional outdoor modules consist of a light board, a base shell, and a faceplate. After assembly, a single module can be tested for illumination and aging. During aging, the module is directly attached to the aging rack using magnets on the base shell. A transmitting card connects multiple modules via a ribbon cable for signal transmission. When assembling a screen, several modules are magnetically attached to the cabinet. The transmitting card hangs directly without affecting the transmission effect. The new product has a different structural design. Signals and power are transmitted through a HUB board. One HUB board connects four modules. The HUB board is relatively large. The male connector on the HUB is directly plugged into the female connector on the module. It does not need to be connected by ribbon cable. Hanging it directly outside the aging rack will affect the transmission effect.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0028] Please see Figures 1-3 This disclosure provides a display module aging test fixture 100 for assembly onto an aging rack for aging testing. It should be noted that in this embodiment, the aging rack can be a structure suitable for conventional group aging tests, having multiple interconnected crossbeams and uprights 200. The display module aging test fixture 100 is assembled onto the uprights 200 of the aging rack for aging testing, without requiring any changes to the existing aging rack structure.
[0029] The display module aging test fixture 100 includes a display module 10, a HUB board 20, and a fixing plate 30 connected in sequence. The module size of the display module 10 can be, for example, 250*250mm (1:1). The HUB board 20 serves as a connection platform and is electrically connected to the display module 10. The HUB board 20 integrates signal and power; both the signals and power of the display module 10 are transmitted through the HUB board 20.
[0030] In this embodiment, the side of the display module 10 facing the HUB board 20 is provided with a female connector 11. The HUB board 20 is provided with a male connector 21 and a fixing part 22.

The first locking member 23 is configured as a screw, and the first connecting portion 31 is configured as a positioning post fixed on the fixing plate 30. The end of the positioning post is provided with a locking groove 311, and the locking groove 311 is provided with a thread adapted to the screw. The fixing portion 22 of the HUB plate 20 is configured as a locking hole. The screw passes through the fixing portion 22 and locks into the locking groove 311 of the positioning post, thereby fixing the HUB plate 20 to the fixing plate 30.
[0032] Furthermore, the multiple fixing parts 22 on the HUB board 20 are arranged in multiple rows, with at least two fixing parts 22 in each row. For example, two fixing parts are provided in the upper, upper middle, lower middle and lower parts of the HUB board 20, for a total of eight fixing parts 22. Correspondingly, eight first connecting parts 31 (positioning posts) are provided in the corresponding positions on the fixing plate 30 to ensure a firm connection with the fixing plate 30.
[0033] It should be noted that in other embodiments, the fixing part 22 and the first connecting part 31 can also be other detachable connection methods. For example, the fixing part 22 and the first connecting part 31 are respectively hook and slot structures, which are engaged by hook and slot.
[0034] Furthermore, in one embodiment, the fixing plate 30 is provided with a plurality of second connecting portions 32, and the second connecting portions 32 and the uprights 200 of the aging rack are locked and fixed by second locking members 33. Specifically, the second locking member 33 is configured as a screw, the second connecting portion 32 is configured as a locking hole, and the upright 200 is provided with a threaded hole adapted to the position of the second locking member 33. The screw passes through the second connecting portion 32 and locks into the threaded hole of the upright 200, thereby fixing the fixing plate 300 to the uprights 200 of the aging rack.
[0035] Furthermore, in one embodiment, the fixing plate 30 is generally H-shaped, including a main board body 301 and extension plates 302 disposed at the four corners of the main board body 301. The main board body 301 generally coincides with the projection of the HUB board 20 in the z-axis direction. A first connecting portion 31 is formed in the main board body 301, and a second connecting portion 32 is formed in the extension plate 302. Figure 1 As shown, the z-axis direction is the connection direction between the HUB plate 20 and the fixed plate 30. Furthermore, each of the four corner extension plates 302 is provided with one or more second connecting portions 32.
[0036] Furthermore, in one embodiment, the HUB board 20 is provided with a plurality of male connectors 21, each male connector 21 being inserted into and mated with a plurality of female connectors 11 of the display modules 10. Specifically, along the x-axis direction, the HUB board 20 is provided with at least two male connectors 21, each male connector 21 being inserted into the female connectors 11 of two display modules 10. Along the y-axis direction, the HUB board 20 is provided with at least two male connectors 21, each male connector 21 being inserted into the female connectors 11 of two display modules 10. For example, in one embodiment, the HUB board 20 is provided with four male connectors 21, arranged in a 2*2 configuration, each of the four male connectors 21 being inserted into the female connectors 11 of four display modules 10.
