[0001] This utility model relates to the field of driving power supply technology, specifically a backlight driving power supply module. Background Technology

[0002] A backlight is a light source located behind a liquid crystal display (LCD), and its emission effect directly affects the visual effect of the liquid crystal display module (LCM). The LCD itself does not emit light; it displays graphics or the result of its modulation of light. The driver power module is used to connect to mains power and convert it into a current and voltage suitable for the light source to operate normally. Existing driver power supply housings typically consist of a bottom shell and a front cover, which enclose a housing space containing the driver power module. In this type of driver power supply housing, the function is simply to house and protect the driver power module.

[0003] Existing power module housings cannot adjust the number of input and output wiring connections for different lighting fixtures. When adding additional functions, the limited number of wiring holes makes it inconvenient. Furthermore, directly adding multiple sets of wiring holes can easily allow foreign objects to enter the housing, affecting the operation of the power module. Moreover, existing power module housings can only be used for power modules of a single size. When the size of the power module changes, the housing becomes unsuitable, which may cause the power module to shake inside the housing and lead to damage. Therefore, we need to propose a backlight driver power module. Utility Model Content

[0009] Preferably, the two sets of toothed plates are symmetrically arranged on both sides of the toothed plate, and the power module housing has two sets of moving slots corresponding to the toothed plates and the extension column. The power module housing also has a rotating slot corresponding to the toothed plate, and the two sets of moving slots are connected to the rotating slot.

[0010] Preferably, the drive module further includes a control rotation column and a support ring. One end of the rotation column is threaded through the side plate and connected to the front clamping plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides: a backlight driving power supply module, such as Figure 1-5As shown, the power module housing 1 includes a power module housing 1 for installing power modules of different sizes. Several sets of connection holes 7 are opened on one side of the power module housing 1. A side plate 3 is bolted to the side of the power module housing 1 away from the connection holes 7. Several sets of ventilation grilles 5 are provided on both sides of the power module housing 1, and dustproof nets are provided inside the ventilation grilles 5 to prevent dust from entering the power module housing 1 and affecting the operation of the drive power supply. At the same time, bolting plates 13 are provided on both sides of the power module housing 1 for bolting and fixing the power module housing 1, so as to facilitate fixing the power module housing 1.

[0025] Preferably, the power module housing 1 has a shielding assembly inside for shielding the connection hole 7. The shielding assembly includes a baffle 6, an operating post 18, and a spring plunger 19. Limiting blocks 17 are provided on both sides of the baffle 6. The spring plunger 19 is fixedly located on the side of the limiting block 17 away from the side plate 3. The operating post 18 is fixedly located on the side of the baffle 6 away from the side plate 3. A shielding groove 20 corresponding to the baffle 6 and the limiting block 17 is opened on the side of the power module housing 1. An operating groove 21 corresponding to the operating post 18 is opened on one side of the power module housing 1. A positioning hole corresponding to two sets of spring plungers 19 is provided on one side. A baffle 6 and a limiting block 17 are provided to move up and down inside the blocking groove 20. An operating groove 21 is provided to facilitate the operation column 18 to drive the baffle 6 to move. Depending on whether the connecting hole 7 is used, the baffle 6 can be moved above or inside the connecting hole 7. When the baffle 6 is located above or below, a positioning hole corresponding to the spring plunger 19 is provided. The baffle 6 is limited by the spring plunger 19 being inserted into the positioning hole, thereby preventing the baffle 6 from being unable to be limited and affecting the use of the connecting hole 7.

[0026] Furthermore, a clamping module for clamping power modules of different sizes is provided inside the power module housing 1. The clamping module includes a front clamping plate 10, a side clamping plate 11, and a drive module. The front clamping plate 10 is slidably disposed inside the side plate 3. Two sets of side clamping plates 11 are provided, and the two sets of side clamping plates 11 are slidably disposed inside the power module housing 1. An upper clamping block 9 is fixedly disposed on the upper surface of the front clamping plate 10. The upper clamping block 9 is a protrusion, and a slot corresponding to the upper clamping block 9 is opened at the top of the power module housing 1. Several sets of ventilation holes are opened on the sides of the front clamping plate 10 and the side clamping plate 11 to avoid affecting the heat dissipation of the drive power after the front clamping plate 10 and the side clamping plate 11 clamp the drive power. At the same time, the upper clamping block 9 is set to move along the inside of the slot to limit the front clamping plate 10 and prevent the front clamping plate 10 from rotating when it moves.

[0027] Furthermore, the drive module includes an adjusting column 2, a toothed plate 12, and a toothed plate 14. Two sets of toothed plates 12 are provided, and the two sets of toothed plates 12 are fixedly connected to the corresponding upward movement through an extension column. The two sets of toothed plates 12 are slidably disposed inside the power module housing 1. The toothed plate 14 is rotatably disposed inside the power module housing 1. The adjusting column 2 is fixedly disposed on the upper surface of the toothed plate 14, and the toothed plate 14 is engaged between the two sets of toothed plates 12. When the toothed plate 14 is rotated by the adjusting column 2, the toothed plate 14 drives the toothed plates 12 on both sides to move through the engagement. Thus, the two sets of toothed plates 12 drive the two sets of side clamping plates 11 to move towards each other or away from each other, thereby facilitating the adjustment of the position of the side clamping plates 11 to clamp the drive power supply. This prevents drive power supplies of different sizes from shaking inside the power module housing 1 after installation, thus preventing damage caused by shaking of drive power supplies of different sizes.

[0028] It is worth noting that the two sets of toothed plates 12 are symmetrically arranged on both sides of the toothed plate 14. The power module housing 1 has two sets of moving grooves 15 corresponding to the toothed plates 12 and the extension column. The power module housing 1 has a rotating groove 16 corresponding to the toothed plate 14. Both sets of moving grooves 15 are connected to the rotating groove 16. The two sets of moving grooves 15 ensure that the two sets of toothed plates 12 can move linearly along the inside of the moving grooves 15. The toothed plate 14 rotates inside the rotating groove 16. At the same time, when the toothed plate 14 rotates, it meshes with the toothed plates 12 inside the two sets of moving grooves 15 through the outer arc surface teeth, thereby achieving the effect of synchronously driving the two sets of toothed plates 12 to move.

[0029] Specifically, the drive module also includes a control rotation column 4 and a support ring 8. One end of the rotation column 4 is threaded through the side plate 3 and connected to the front clamping plate 10. The support ring 8 is fixedly set on the outside of the side plate 3 and sleeved on the outer arc surface of the rotation column 4. When the side plate 3 is bolted to the side of the power module housing 1, the front clamping plate 10 is located inside the power module housing 1, and the upper locking block 9 will be locked into the slot. Then, rotating the rotation column 4 will drive the baffle 6 to move inside the power module housing 1. The support ring 8 is set to support the rotation column 4 to prevent the rotation column 4 from tilting when the threaded rotation of the side plate 3 occurs.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
