Description

Technical Field

[0001] This utility model relates to the field of LED ceiling light technology, specifically to a PCB board structure for an LED ceiling light. Background Technology

[0002] Circuit boards are widely used in various electronic devices. Circuit boards can electrically connect multiple electronic components to each other. For example, in the field of LEDs, LEDs are currently soldered onto PCB circuit boards with pure tin. Existing LEDs are usually installed in the LEDs using screws.

[0003] When replacing the PCB board of a ceiling light, the operator needs to accurately align the holes on the PCB board with the corresponding holes on the lamp housing during the actual assembly process. This operation requires adjustment and calibration. Moreover, due to the lack of an effective guiding mechanism in the hole alignment process, slight deviations can easily lead to misaligned screws after installation, which can damage the lamp housing and the PCB board. Therefore, a PCB board structure for LED ceiling lights is proposed to address the above situation. Utility Model Content

[0004] The purpose of this utility model is to provide a PCB board structure for an LED ceiling light. Through the structural design of guide grooves, positioning grooves and guide columns, the reserved holes on the outer shell of the PCB board body can be calibrated and aligned during the assembly process. This makes it easier for workers to use screws to fasten the PCB board body to the outer shell. It solves the problem that the screws are easily misaligned after installation due to slight deviations caused by the lack of an effective guiding mechanism in the hole alignment process.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a PCB board structure for an LED ceiling light, comprising a PCB board body, a guide groove on the outer surface of the PCB board body, a base support fixed to the bottom of the PCB board body, and an outer shell surrounding the PCB board body. The outer shell has a circular groove, a guide post is fixed inside the circular groove, and a positioning component is provided on the guide post. When the PCB board body is assembled on the outer shell, the guide post cooperates with the guide groove, the positioning component cooperates with the guide groove, and the base support contacts the bottom of the circular groove.

[0007] Furthermore, the PCB board body has four screw holes, four base plates, and four positioning slots, all of which are staggered with each other.

[0008] Furthermore, positioning grooves are provided on both sides of the inner wall of the guide groove, and the positioning grooves are trapezoidal.

[0009] Furthermore, four guide posts are fixed inside the circular groove of the outer shell.

[0010] Furthermore, the positioning component includes grooves formed on both sides of the outer wall of the guide post, with springs fixed on the grooves and positioning blocks fixed at one end of the springs. When the guide post mates with the guide groove, the positioning blocks mate with the positioning groove.

[0011] Furthermore, support blocks are fixed on both sides of the outer wall of the guide column, and the bottom of the PCB board body contacts the support blocks.

[0012] Furthermore, ventilation holes are provided on the outer casing, and threaded holes are provided in the circular groove of the outer casing. There are four threaded holes, each corresponding to a screw hole.

[0013] This utility model has the following beneficial effects:

[0014] This utility model, through the structural design of guide grooves, positioning grooves and guide pillars, allows the PCB board body to be aligned with the reserved holes on the outer shell during the assembly process through the cooperation of the guide grooves and guide pillars. This makes it easier for workers to use screws to fasten the PCB board body to the outer shell.

[0015] This utility model, through the structural design of positioning groove, groove, spring and positioning block, can achieve the initial positioning treatment of the PCB board body when the guide groove and guide post are in coordination, so as to ensure that the workers can use screws for further fixing and installation. In addition, the setting of the base makes the PCB board body and the shell have a gap, which allows the components to dissipate heat more quickly when they are working.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a PCB board structure for an LED ceiling light, including a PCB board body 1 on which several LED beads are soldered. A guide groove 100 is formed on the outer surface of the PCB board body 1, and positioning grooves 101 are formed on both sides of the inner wall of the guide groove 100. The positioning grooves 101 are trapezoidal. A base support 102 is fixed to the bottom of the PCB board body 1. The base support 102 is made of a high-strength, well-insulated material, such as engineering plastic or insulating ceramic. Its main function is to provide stable support by ensuring close contact between the PCB board body 1 and the bottom of the circular groove of the outer shell 2 when the PCB board body 1 is installed on the outer shell 2. The PCB board body 1 has four screw holes 103, four base supports 102, and four positioning grooves 101, all of which are staggered.

[0024] The PCB board body 1 is surrounded by an outer shell 2, which is the ceiling light housing. The outer shell 2 has a circular groove, and a guide post 3 is fixed in the circular groove. A positioning component is provided on the guide post 3.

[0025] Ventilation holes 200 are provided on the outer casing 2, and threaded holes are provided in the circular groove of the outer casing 2. There are four threaded holes, which correspond one-to-one with the screw holes 103.

[0026] The ventilation holes 200 are divided into upper and lower sets, which are respectively matched with the top and bottom surfaces of the installed PCB board body 1, thereby enhancing the airflow on the top and bottom surfaces of the PCB board body 1 and accelerating heat dissipation. Each set of ventilation holes 200 consists of several holes, which are opened along the outer wall of the outer shell 2. Dustproof nets can be installed on the ventilation holes 200 according to the actual use.

[0027] After the PCB board body 1 is initially installed, screws are used to pass through the screw holes 103 and engage with the threaded holes in the circular groove to fix the PCB board body 1.

[0028] When the PCB board body 1 is assembled on the outer shell 2, the guide post 3 cooperates with the guide groove 100, the positioning component cooperates with the guide groove 100, and the bottom support 102 contacts the bottom of the circular groove.

[0029] The outer casing 2 has four guide posts 3 fixed in the circular groove. The positioning component includes grooves 300 formed on both sides of the outer wall of the guide post 3. A spring 301 is fixed on the groove 300. A positioning block 302 is fixed to one end of the spring 301. When the guide post 3 is engaged with the guide groove 100, the positioning block 302 is engaged with the positioning groove 101.

[0030] The positioning block 302 cooperates with the positioning groove 101, and its shape matches the positioning groove 101. It is made of engineering plastic or metal material with moderate hardness. When the guide post 3 is inserted into the guide groove 100, the positioning block 302 automatically snaps into the positioning groove 101 under the elastic force of the spring 301, realizing the initial positioning of the PCB board body 1. This positioning method can not only quickly and accurately realize the positioning of the PCB board and the shell, but also effectively prevent the PCB board from shifting during the subsequent screw fixing process, reduce the installation difficulty, and improve the installation efficiency.

[0031] Both sides of the outer wall of the guide column 3 are fixed with support blocks 303, and the bottom of the PCB board body 1 is in contact with the support blocks 303.

[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
