Description

Technical Field

[0001] The utility model relates to the field of HAHA, and specifically relates to a structure of an LED light source board. Background Technique

[0002] The LED light source is a light-emitting diode light source. LED lamps have the characteristics of high brightness, low power consumption, long service life, etc., and have gradually replaced traditional light sources and become the most commonly used lamps in life. In the structure of an LED lamp, the part where the light-emitting unit is fixed is the LED light source board.

[0003] Conventional LED light source boards are usually installed in the lamp housing of a lamp by means of screw fixation or glue bonding. However, these two installation methods are rather cumbersome during the installation process and need to be improved. For example, the Chinese patent document with the publication number CN220770956U discloses an LED light source board, belonging to the field of LED light source boards, including a lamp housing and an LED light source board body. Installation mechanisms are respectively arranged on the left and right sides of the inner bottom surface of the lamp housing. When the LED light source board body is installed into the lamp housing, the positioning columns installed in the lamp housing are correspondingly inserted into the positioning holes opened on the LED light source board body, and the limiting plate is turned upward to leave the limiting rod to release the restriction on the baffle plate.

[0004] The above document completes the fixation of the LED light source board through the cooperation of multiple components such as springs. The structure is complex and the operation is cumbersome, which not only increases the input cost but also brings a burden to the manufacturing and assembly of the device.

The connecting plates are fixed to the inner wall of the lamp panel by bolts. A pressure rod is rotatably installed on the connecting plates. U-shaped sections are integrally formed at both ends of the pressure rod. A pair of upright ears are arranged at one end of the connecting plate close to the lamp board. Grooves for accommodating the pressure rod are respectively arranged on the pair of upright ears. Square holes for accommodating the U-shaped sections are opened at positions corresponding to the connecting plates on the top of the lamp board, so that the pressure rod rotates until the U-shaped sections are inserted into the square holes to complete the limitation of the lamp board.

[0007] Preferably, a through hole is arranged on the top of the connecting plate, and a pressing plate is arranged on the inner wall of one side of the through hole.

[0008] Preferably, an arc-shaped cavity for accommodating the pressing rod is integrally formed by bending the pressing plate.

[0009] Preferably, the corners of the connecting plate are all smoothly transitioned with rounded corners.

[0010] Preferably, the pressing rod is integrally formed by bending into a dovetail structure with a bent section.

[0011] Preferably, the bent section and the U-shaped section are connected and transitioned through a horizontal section, and the horizontal section abuts against the card slot.

[0012] Preferably, four circular holes for bolts to penetrate are provided at the top of the connecting plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The present utility model completes the fixation of the lamp board in the lamp tray through the cooperation of the connecting plate and the pressing rod. The bent section generated by bending the pressing rod makes elastic movement to cooperate with the U-shaped section to limit the lamp board, effectively improving the disassembly and assembly efficiency of the lamp board, and having a simple structure and convenient operation.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer toFigures 1 - 4 , the present utility model provides a technical solution: an LED light source board structure, including a lamp panel 1, further including a lamp board 2 and several connecting plates 3. An installation groove for accommodating the lamp board 2 is reserved on the bottom wall of the lamp panel 1. Four circular holes 10 for bolt penetration are provided on the top of the connecting plate 3. The connecting plate 3 is fixed to the inner wall of the lamp panel 1 by bolts. At the installation position of the connecting plate 3 at the bottom of the lamp panel 1, screw holes for bolt installation are also provided. A pressing rod 4 is rotatably installed on the connecting plate 3. A through hole 11 is provided on the top of the connecting plate 3. The setting of the through hole 11 can reduce the weight of the connecting plate 3 and perform a lightweight design on the connecting plate 3. A pressing plate 5 is provided on one inner wall of the through hole 11. The pressing plate 5 is integrally formed with a bent arc-shaped cavity for accommodating the pressing rod 4, providing support for the pressing rod 4 and enabling the pressing rod 4 to make a circular motion around the axis of the arc-shaped cavity. The corners of the connecting plate 3 are all smoothly transitioned with rounded corners. The advantage of this setting is to avoid scratching the skin during installation due to sharp corners. The pressing rod 4 is integrally formed by bending into a dovetail structure with a bent section 7. The pressing rod 4 itself has elasticity. The setting of the dovetail structure enables the two ends of the pressing rod 4 to have a restoring force after being pressed. U-shaped sections 12 are integrally formed at both ends of the pressing rod 4. A pair of upright ears 9 are provided at one end of the connecting plate 3 close to the lamp board 2. Card slots 8 for accommodating the pressing rod 4 are respectively provided on the pair of upright ears 9. The bent section 7 and the U-shaped section 12 are connected and transitioned through a horizontal section. The horizontal section abuts against the card slot 8. The setting of the card slot 8 is used for anti-detachment and limit of the pressing rod 4. A pair of square holes 6 for accommodating the U-shaped sections 12 are opened at the corresponding positions of the top of the lamp board 2 and the connecting plate 3, so that the pressing rod 4 can be rotated until the U-shaped sections 12 are inserted into the square holes 6 to complete the limit of the lamp board 2. When installing the lamp board 2 in this application, place the lamp board 2 in the installation groove reserved on the bottom wall of the lamp panel 1. Then pinch the two ends of the pressing rod 4 to make the U-shaped sections 12 at both ends of the pressing rod 4 approach each other. Rotate the pressing rod 4 to make it make a circular motion around the pressing plate 5 until the U-shaped sections 12 are inserted into the square holes 6 of the lamp board 2. At this time, the horizontal section of the pressing rod 4 is located between the pair of upright ears 9. Release the U-shaped sections 12, and the pressing rod 4 elastically moves back to make the horizontal section abut against the card slot 8, completing the limit of the lamp board 2. When disassembling the lamp board 2, pinch the U-shaped sections 12 until the horizontal section of the pressing rod 4 is far away from the card slot 8 and then rotate the pressing rod 4, that is, the U-shaped sections 12 release the limit on the square holes 6, and the lamp board 2 can be removed. This application completes the fixation of the lamp board 2 in the lamp panel 1 through the cooperation of the connecting plate 3, the pressing rod 4 and the lamp board 2. The bent section 7 generated by bending the pressing rod 4 makes an elastic motion and cooperates with the U-shaped section 12 to limit the lamp board 2, effectively improving the disassembly and assembly efficiency of the lamp board 2, and having a simple structure and convenient operation. Compared with the complex structure of the prior art, this application is more convenient for manufacturing and assembly and is suitable for mass production.
