Description

Technical Field

[0001] This invention belongs to the field of circuit board technology, and specifically relates to a power line carrier circuit board for LED smart lighting. Background Technology

[0002] Currently, circuit boards on the market are manufactured by soldering different components onto them. During installation, the circuit board is positioned using through-holes at its corners and then secured with screws. However, during this process, the corners of the circuit board are prone to breakage, rendering the entire board unusable.

[0003] Therefore, it is necessary to invent a power line carrier circuit board for LED smart lighting to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a power line carrier circuit board for LED smart lighting, thereby solving the issues raised in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power line carrier circuit board for LED smart lighting, comprising a base plate, a PCB board placed on top of the base plate, vertical rods fixed at the four corners of the top surface of the base plate, top plates on both sides of the top of the base plate, and the top ends of two vertical rods respectively connected to the bottom surfaces of the top plates. A collar is fitted onto the surface of the vertical rod, a movable frame is fixed inside the collar, a pressure plate is provided at the opening inside the movable frame, a buffer structure connecting the pressure plate is provided inside the movable frame, and the bottom surface of the inner end of the pressure plate corresponds to the top surface of the PCB board. A nut is provided at the top of the collar, which is screwed onto the surface of the vertical rod. When the nut rotates on the surface of the vertical rod, causing the collar to move downward, the collar uses the buffer structure inside the movable frame to drive the pressure plate to squeeze the PCB board. A limiting structure for limiting the collar is provided at the top of the base plate.

[0006] Furthermore, the buffer structure includes a movable rod, the top and bottom of which penetrate the top and bottom surfaces of the movable frame, respectively. The outer end of the pressure plate is located inside the movable frame and is fixedly connected to the movable rod. A spring is installed inside the movable frame, with the top of the spring connected to the inner top surface of the movable frame and the bottom of the spring connected to the top surface of the pressure plate. The downward-moving movable frame causes the inner end of the pressure plate to press against the top surface of the PCB board through the elastic force of the spring.

[0007] Furthermore, a limiting plate is fixed to the bottom end of the movable rod, and a groove corresponding to the limiting plate is provided on the top surface of the bottom plate. The movable rod drives the limiting plate to move up and down inside the groove. A baffle is fixed to the top inner side of the limiting plate, and a notch corresponding to the baffle is provided at the bottom of the inner side of the movable frame. The inner side of the baffle is flush with the inner side of the movable frame.

[0008] Furthermore, the defined structure includes a first sliding frame and a second sliding frame. The first sliding frame is located at the front side of the second sliding frame, and the top surfaces of both ends of the first and second sliding frames are respectively attached to the bottom surfaces of the two top plates. A plurality of protruding rods penetrating the second sliding frame are fixed to the top of the rear side of the first sliding frame. A spring piece is provided between the first and second sliding frames, and the front and rear ends of the spring piece are respectively connected to the rear side of the first sliding frame and the front side of the second sliding frame.

[0009] Furthermore, the first and second sliding frames are respectively connected to the collars on the surfaces of multiple vertical rods. The top of the rotating plate is hinged to the collar surface. Screws pass through the ends of the first and second sliding frames. The screws pass through the bottom of the rotating plate, and the inner end of the screws is screwed with a threaded sleeve. The ends of the first and second sliding frames are rotated with the bottom of the rotating plate using screws. The rotating plates connected to the first and second sliding frames are arranged opposite each other.

[0010] Furthermore, the ends of the first and second sliding frames are respectively attached to the top surface of the base plate, and the first and second sliding frames are vertically arranged. Multiple downward-moving collars push the first and second sliding frames to move through the rotating plate.

[0011] Furthermore, L-shaped plates are provided on both the front and rear sides of the top of the base plate. The L-shaped plates include a horizontal part and a vertical part. The bottom surfaces of the horizontal parts of the two L-shaped plates arranged in front and behind are respectively attached to the top surfaces of the first slide frame and the second slide frame. Multiple screws are spirally passed through the top surfaces of the horizontal parts. The bottom ends of the multiple screws pass through the tops of the first slide frame and the second slide frame respectively. The first slide frame and the second slide frame are fixedly connected to the two L-shaped plates by screws.

[0012] Furthermore, the bottom of the vertical part of the L-shaped plate is attached to the top surface of the base plate, and a rubber plate is fixed to the bottom of the inner side of the vertical part, with the two rubber plates located on the front and rear sides of the PCB board respectively.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. This invention uses a collar to move the movable frame downwards. The downward-moving movable frame uses the elastic force of a spring to facilitate the cooperation of multiple pressure plates to press against the top surface of the PCB board, ensuring the stability of the PCB board on the top of the base plate. The elastic force of the spring prevents the pressure plates from directly pressing against the PCB board, and the rubber pressure plates prevent the edges and corners of the PCB board from breaking or being damaged during the pressing process.

[0015] 2. The present invention gradually brings two L-shaped plates closer together until the rubber plate on the inner side of the vertical part of the L-shaped plate squeezes the end face of the PCB board, which further improves the stability of the PCB board on the top surface of the base plate. In addition, the first sliding frame and the second sliding frame, together with the L-shaped plate, improve the protection effect of the PCB board and prevent external parts from directly impacting the surface of the PCB board.

[0016] 3. The present invention prevents the movable frame from moving by cooperating with the groove, thereby preventing the fixed collar of the movable frame from rotating on the surface of the vertical rod, ensuring the stability of the movable frame moving downward. Furthermore, the downward limiting plate limits the pressure plate by the movable rod, preventing the pressure plate from shaking on the top surface of the PCB board during the pressing process.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] This invention provides a power line carrier circuit board for LED smart lighting, such as... Figure 1 and Figure 2As shown, the system includes a base plate 1, on which a PCB board 2 is placed. Vertical rods 3 are fixed at the four corners of the top surface of the base plate 1. Top plates 4 are provided on both sides of the top surface of the base plate 1. The bottom surfaces of the top plates 4 are respectively connected to the top ends of the two vertical rods 3. A collar 5 is fitted onto the surface of the vertical rod 3. A movable frame 6 is fixed inside the collar 5. A pressure plate 7 is provided at the opening inside the movable frame 6. The pressure plate 7 is made of rubber material. A buffer structure connecting the pressure plate 7 is provided inside the movable frame 6. The bottom surface of the inner end of the pressure plate 7 corresponds to the top surface of the PCB board 2. A nut 8 is provided at the top of the collar 5, which is screwed onto the surface of the vertical rod 3. When the nut 8 rotates on the surface of the vertical rod 3, it causes the collar 5 to move downward. The collar 5 uses the buffer structure inside the movable frame 6 to drive the pressure plate 7 to squeeze the PCB board 2. A limiting structure is provided at the top of the base plate 1 to limit the collar 5. After the PCB board 2 is placed on the top surface of the base plate 1, the pressure plates 7 with openings on the inner sides of the multiple movable frames 6 are positioned on the top of the PCB board 2. When the nut 8 is rotated, the spiral effect of the nut 8 and the vertical rod 3 causes the collar 5 to move down on the surface of the vertical rod 3. The moving collar 5 moves the pressure plate 7 down through the movable frames 6, and the inner end of the moving pressure plate 7 gradually presses against the top of the PCB board 2. Through the pressure of the multiple pressure plates 7, the PCB board 2 is stably fixed on the top of the base plate 1.

[0025] exist Figure 1 In the design, PCB board 2 includes a microcontroller (MCU). The live and neutral wires supply power to the MCU via an AC / DC module, a filter module, an isolated power supply module, and a voltage regulator module. The AC / DC module converts the alternating current (AC) from the live and neutral wires into direct current (DC). The filter, isolated power supply, and voltage regulator modules then stabilize the converted DC into a stable DC power supply, which directly powers the MCU, ensuring stable power supply to the MCU. The MCU is externally connected to an infrared receiver and a digital dimming module.

[0026] In this circuit, TXD is the pin for transmitting data by the microcontroller (MCU), and RXD is the pin for receiving data by the MCU. The MCU analyzes the signal received by the infrared receiver, sends the operating command through the transmitter, amplifies it through a modulator and amplifier, and then evenly distributes it to the device via a coupler. The device's operating signal is then evenly distributed through the coupler, detected by a detector, amplified by an amplifier, and rectified before being sent to the MCU to obtain the device's operating signal.

[0027] exist Figure 2 and Figure 3In this design, the buffer structure includes a movable rod 9, with its top and bottom ends penetrating the top and bottom surfaces of the movable frame 6, respectively. The outer end of the pressure plate 7 is located inside the movable frame 6 and is fixedly connected to the movable rod 9. A spring 10 is installed inside the movable frame 6, with its top end connected to the inner top surface of the movable frame 6 and its bottom end connected to the top surface of the pressure plate 7. The downward-moving movable frame 6 uses the elastic force of the spring 10 to cause the inner end of the pressure plate 7 to press against the top surface of the PCB board 2. When the screw nut 8 and the vertical rod 3 spiral together, causing the collar 5 to move downward, the collar 5 uses the buffer structure inside the movable frame 6 to drive the pressure plate 7 downward until the bottom surface of the inner end of the pressure plate 7 contacts the top surface of the PCB board 2. At this point, the movable frame 6 continues to move downward, moving below the surface of the movable rod 9. The movable frame 6 and the pressure plate 7 work together to press against the spring 10. The elastic force of the spring 10 facilitates the coordinated pressing of multiple pressure plates 7 against the top surface of the PCB board 2, ensuring the stability of the PCB board 2 on top of the base plate 1.

[0028] After the bottom surface of the inner end of the pressure plate 7 is attached to the top surface of the PCB board 2, the PCB board 2 itself restricts the pressure plate 7. The downward moving frame 6 uses the elastic force of the spring 10 to make the pressure plate 7 press against the top surface of the PCB board 2, so as to avoid the moving frame 6 driving the pressure plate 7 to directly press against the top surface of the PCB board 2, and to avoid the top surface of the PCB board 2 being subjected to excessive pressure and thus damaged.

[0029] exist Figures 2 to 4 In this configuration, a limiting plate 11 is fixed to the bottom end of the movable rod 9. A groove 12 corresponding to the limiting plate 11 is provided on the top surface of the base plate 1. The movable rod 9 drives the limiting plate 11 to move up and down inside the groove 12. A baffle 13 is fixed to the inner top surface of the limiting plate 11. A notch corresponding to the baffle 13 is provided at the bottom of the inner side of the movable frame 6, and the inner side of the baffle 13 is flush with the inner side of the movable frame 6. After the PCB board 2 is placed on the top surface of the base plate 1, the limiting plate 11 uses the baffle 13 to limit the side of the PCB board 2, so that the side of the PCB board 2 is in contact with the side of the baffle 13, preventing the side of the PCB board 2 from moving to the top of the groove 12 and preventing the pressure of the pressure plate 7 from causing the side of the PCB board 2 to break at the top of the groove 12. When the movable frame 6 moves the pressure plate 7 downward, the limiting plate 11 at the bottom of the movable rod 9 moves downward inside the groove 12 until the bottom surface of the inner end of the pressure plate 7 is in contact with the top surface of the PCB board 2. At this time, the bottom end of the movable frame 6 is inside the groove 12. When the movable frame 6 continues to move downward, the movable frame 6 compresses the spring 10, and the bottom end of the movable frame 6 moves downward inside the groove 12. The cooperation between the movable frame 6 and the groove 12 prevents the movable frame 6 from moving, thereby preventing the fixed collar 5 of the movable frame 6 from rotating on the surface of the vertical rod 3, ensuring the stability of the downward movement of the movable frame 6. The downward-moving limiting plate 11 limits the pressure plate 7 through the movable rod 9, preventing the pressure plate 7 from shaking on the top surface of the PCB board 2 during the pressing process.

[0030] exist Figure 2 and Figure 5In this structure, the defined structure includes a first sliding frame 14 and a second sliding frame 15. The first sliding frame 14 is located in front of the second sliding frame 15, and the top surfaces of both the first sliding frame 14 and the second sliding frame 15 are respectively attached to the bottom surfaces of the two top plates 4. A plurality of protruding rods 16 penetrating the second sliding frame 15 are fixed to the top of the rear side of the first sliding frame 14. A spring piece 17 is provided between the first sliding frame 14 and the second sliding frame 15, with its front and rear ends connected to the rear side of the first sliding frame 14 and the front side of the second sliding frame 15, respectively. The first sliding frame 14 and the second sliding frame 15, arranged side by side, are located on the top of the PCB board 2. The elasticity of the spring piece 17 causes the first sliding frame 14 and the second sliding frame 15 to separate until the elasticity of the spring piece 17 disappears, at which point the distance between the first sliding frame 14 and the second sliding frame 15 reaches its maximum. Multiple protruding rods 16 are inserted into the top of the second sliding frame 15 at their rear ends. The multiple protruding rods 16 ensure that the first sliding frame 14 and the second sliding frame 15 are aligned and flush. The bottom ends of the first sliding frame 14 and the second sliding frame 15 are attached to the top surface of the base plate 1, and the top surfaces of the first sliding frame 14 and the second sliding frame 15 are attached to the bottom surface of the top plate 4, so that the first sliding frame 14 and the second sliding frame 15 are both in a vertical state.

[0031] The first sliding frame 14 and the second sliding frame 15 are respectively connected at both ends to the collars 5 on the surfaces of the multiple vertical rods 3. The top of the rotating plate 18 is hinged to the surface of the collar 5. Screws 19 penetrate the ends of the first sliding frame 14 and the second sliding frame 15, respectively. The screws 19 penetrate the bottom end of the rotating plate 18, and the inner end of the screws 19 is screwed with a threaded sleeve 20. The ends of the first sliding frame 14 and the second sliding frame 15 are rotatably engaged with the bottom end of the rotating plate 18 by means of the screws 19. The rotating plate 18, which is connected to the first sliding frame 14 and the second sliding frame 15, is arranged opposite to each other. The ends of the first sliding frame 14 and the second sliding frame 15 are respectively attached to the top surface of the base plate 1, and the first sliding frame 14 and the second sliding frame 15 are arranged vertically. The multiple downward-moving collars 5 push the first sliding frame 14 and the second sliding frame 15 to move through the rotating plate 18. The spiral effect of the screw sleeve 20 and the screw 19 connects the ends of the first slide frame 14 and the second slide frame 15 to the bottom of the rotating plate 18. When the spiral effect of the rotating nut 8 and the vertical rod 3 pushes the collar 5 down, the lowering collar 5 drives the top of the rotating plate 18 down. Due to the limitation of the bottom of the rotating plate 18 by the ends of the first slide frame 14 and the second slide frame 15, the bottom of the rotating plate 18 is prevented from moving up and down. At this time, the lowering bottom of the rotating plate 18 causes the rotating plate 18 to rotate. The rotating bottom of the rotating plate 18 pushes the first slide frame 14 and the second slide frame 15 to move. At this time, the first slide frame 14 and the second slide frame 15 gradually approach each other during the sliding process. The protruding rod 16 slides inside the second slide frame 15, and the first slide frame 14 and the second slide frame 15, which are close to each other, cooperate to squeeze the spring piece 17. The elastic force of the spring piece 17 is applied to the bottom end of the rotating plate 18 through the first sliding frame 14 and the second sliding frame 15. At this time, the elastic force is transmitted to the collar 5 through the rotating plate 18. The bottom surface of the nut 8 is attached to the bottom surface of the collar 5. The up and down movement of the movable frame 6 is controlled by the spiral effect of the rotating nut 8 and the vertical rod 3, as well as the elastic force of the spring piece 17.

[0032] exist Figure 2 and Figure 5In the PCB board 2, L-shaped plates 21 are provided on both the front and rear sides of the top of the base plate 1. Each L-shaped plate 21 includes a horizontal portion and a vertical portion. The bottom surfaces of the horizontal portions of the two L-shaped plates 21 arranged in a front-to-back configuration are respectively attached to the top surfaces of the first sliding frame 14 and the second sliding frame 15. Multiple screws 22 are spirally threaded through the top surfaces of the horizontal portions. The bottom ends of the screws 22 respectively pass through the tops of the first sliding frame 14 and the second sliding frame 15, and the first sliding frame 14 and the second sliding frame 15 are fixedly connected to the two L-shaped plates 21 by the screws 22. The bottom ends of the vertical portions of the L-shaped plates 21 are correspondingly attached to the top surface of the base plate 1. A rubber plate 23 is fixed to the bottom inner side of the vertical portion, and two rubber plates 23 are respectively located on the front and rear sides of the PCB board 2. When the first sliding frame 14 and the second sliding frame 15 approach each other, both the first sliding frame 14 and the second sliding frame 15 use the screw 22 to drive the L-shaped plate 21 to move. That is, the first sliding frame 14 drives the front L-shaped plate 21 to move backward, and the second sliding frame 15 drives the rear L-shaped plate 21 to move forward. The two L-shaped plates 21 gradually approach each other until the L-shaped plate 21 uses the rubber plate 23 on the inner side of the vertical part to press the end face of the PCB board 2. At this time, the movable frame 6 uses the elastic force of the spring 10 to make the inner end of the pressure plate 7 press the top surface of the PCB board 2, further improving the stability of the PCB board 2 on the top surface of the base plate 1.

[0033] Working principle of this invention:

[0034] Reference Figures 2 to 5 As shown, after the PCB board 2 is placed on the top surface of the base plate 1, the pressure plates 7 with the inner openings of the multiple movable frames 6 are located on the top of the PCB board 2. The elastic force of the spring piece 17 is applied to the bottom end of the rotating plate 18 through the first sliding frame 14 and the second sliding frame 15. At this time, the elastic force is transmitted to the collar 5 through the rotating plate 18. The bottom surface of the nut 8 is attached to the bottom surface of the collar 5. The up and down movement of the movable frame 6 is controlled by the spiral effect of the rotating nut 8 and the vertical rod 3 and the elastic force of the spring piece 17.

[0035] When the spiral effect of the nut 8 and the vertical rod 3 causes the collar 5 to move downward, the collar 5 uses the buffer structure inside the movable frame 6 to drive the pressure plate 7 to move downward until the bottom surface of the inner end of the pressure plate 7 contacts the top surface of the PCB board 2. At this time, the movable frame 6 continues to move downward. The movable frame 6 moves downward on the surface of the movable rod 9. The movable frame 6 and the pressure plate 7 cooperate to compress the spring 10. The elastic force of the spring 10 facilitates the cooperation of multiple pressure plates 7 to press on the top surface of the PCB board 2, ensuring the stability of the PCB board 2 on the top of the base plate 1.

[0036] The downward-moving collar 5 causes the top of the rotating plate 18 to move downward. Due to the limitation of the bottom of the rotating plate 18 by the ends of the first sliding frame 14 and the second sliding frame 15, the bottom of the rotating plate 18 is prevented from moving up and down. At this time, the downward-moving bottom of the rotating plate 18 causes the rotating plate 18 to rotate. The rotating bottom of the rotating plate 18 pushes the first sliding frame 14 and the second sliding frame 15 to move. At this time, the first sliding frame 14 and the second sliding frame 15 gradually approach each other during the sliding process. The protrusion 16 slides inside the second sliding frame 15, and the first sliding frame 14 and the second sliding frame 15, which are close to each other, cooperate to squeeze the spring piece 17.

[0037] When the first sliding frame 14 and the second sliding frame 15 approach each other, both the first sliding frame 14 and the second sliding frame 15 use the screw 22 to drive the L-shaped plate 21 to move. That is, the first sliding frame 14 drives the front L-shaped plate 21 to move backward, and the second sliding frame 15 drives the rear L-shaped plate 21 to move forward. The two L-shaped plates 21 gradually approach each other until the L-shaped plate 21 uses the rubber plate 23 on the inner side of the vertical part to press the end face of the PCB board 2. At this time, the movable frame 6 uses the elastic force of the spring 10 to make the inner end of the pressure plate 7 press the top surface of the PCB board 2, further improving the stability of the PCB board 2 on the top surface of the base plate 1.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
