Description

Technical Field

[0001] This utility model relates to the field of light-emitting diode technology, specifically to a wire support for light-emitting diodes. Background Technology

[0002] LED leadframes are key structural components that support and electrically connect LED chips. They are primarily used to fix the chip's position, provide a current path, and assist in heat dissipation. Their core function is to connect the chip to external circuits via wires, while simultaneously providing physical support to the chip, ensuring the stability of the LED during soldering, packaging, and operation.

[0003] If the lead pins of the bracket are too thin or there are defects in the stamping process, they are prone to breakage during welding or assembly. At the same time, in high-frequency vibration scenarios, the connection between the lead pins and the bracket body will crack due to fatigue stress. To address this, we propose a lead pin bracket for light-emitting diodes. Utility Model Content

[0004] The purpose of this invention is to provide a lead wire support for light-emitting diodes (LEDs) to solve the problems mentioned in the background art, such as lead wires being too thin or having stamping process defects, making them prone to breakage during welding or assembly, and cracking at the connection between the lead wires and the support body due to fatigue stress in high-frequency vibration scenarios. To achieve the above objective, this invention provides the following technical solution: a lead wire support for LEDs, comprising a supporting base rod;

[0005] A connecting assembly includes several grooves formed on the side surface of a supporting base rod. The grooves are arranged in a circular array on the side surface of the supporting base rod. A limiting base is fixedly connected to the bottom end of the supporting base rod. A hinge seat is movably connected inside each groove. A hinge shaft is movably connected inside the hinge seat via a hinge. Two hinge plates are movably connected to the side surface of the hinge shaft via hinges. The two hinge plates are symmetrically distributed on the side surface of the hinge shaft. A through column is movably connected inside the two hinge plates.

[0006] The support assembly includes several hinge seats two, which are fixedly connected to the side surface of the support base rod. The hinge seats two are arranged in a ring array on the side surface of the support base rod. A hinge shaft two is movably connected inside the hinge seat two. A connector is fixedly connected to the side surface of the hinge shaft two. A support leg is fixedly connected to one side of the connector. An anti-slip pad is fixedly connected to the bottom end of the support leg.

[0007] More preferably, a connecting column is fixedly connected to the top of the support base rod, and a universal joint is movably connected to the top of the connecting column. The bracket is supported by the connecting assembly and the support assembly. The hinge shaft is rotated by the hinge seat two, thereby causing the hinge shaft two to drive the connecting piece, which in turn causes the connecting piece to drive the support leg to extend outward. The support is then supported by the anti-slip pad in contact with the ground. At the same time, the bottom of the anti-slip pad is provided with a protrusion to increase friction for stabilizing the bracket. The support assembly is further stabilized by the connecting assembly. The hinge plate is connected to the support leg by the through column. When the support leg extends outward, the through column rotates.

[0008] In a further preferred embodiment, a connecting rod is fixedly connected to the top of the universal joint, an adjusting member is movably connected to the side surface of the connecting rod, and a top rod is fixedly connected to the top of the connecting rod. This allows the hinge plate to push the hinge seat to slide within the groove, thereby completing the unfolding of the bracket for support and fixation. This ensures that the bracket is relatively stable during operation, avoids vibration of the bracket, and prevents the bracket pins from being too thin or having stamping process defects, which could easily break during welding or assembly. Additionally, in high-frequency vibration scenarios, the connection between the pins and the bracket body may crack due to fatigue stress.

[0009] More preferably, the side surface of the top rod is movably connected to a sleeve member, and the side surface of the sleeve member is fixedly connected to a fixed power source.

[0010] More preferably, a rotating shaft is movably connected to the side surface of the top rod, a connecting bracket is fixedly connected to the side surface of the rotating shaft, and a circuit board is fixedly connected to the top of the connecting bracket.

[0011] More preferably, a mounting plate is fixedly connected to the top of the circuit board, and a movable shaft is fixedly connected to the top of the top rod. The shaft is then connected to the connecting rod via a connecting column and a universal joint, thereby adjusting the angle of the bracket. At the same time, a fixed power supply is used to power the LED body. The LED body is connected to the circuit board, and the adjustment knob can adjust the angle of the movable shaft. The rotating shaft is used to rotate and adjust the angle of the circuit board, thus making the device highly flexible during use.

[0012] More preferably, each end of the movable shaft is fixedly connected to an adjustment knob, and the two adjustment knobs are symmetrically distributed at both ends of the movable shaft.

[0013] More preferably, a curved plate is fixedly connected to the side surface of the movable shaft, and a light-emitting diode body is fixedly connected to one side of the curved plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the bracket is supported by a connecting assembly and a supporting assembly. The hinge seat rotates the hinge shaft, causing the hinge shaft to drive the connecting piece, which in turn causes the supporting leg to extend outwards. Support is achieved by an anti-slip pad that adheres to the ground. The bottom of the anti-slip pad has protrusions to increase friction and stabilize the bracket. The connecting assembly further stabilizes the supporting assembly. A through-post connects the hinge plate to the supporting leg. When the supporting leg extends outwards, the through-post rotates, causing the hinge plate to push the hinge seat to slide within the groove, thus completing the bracket's unfolding and support fixation. This ensures the bracket is relatively stable during operation, preventing vibration and thus preventing breakage during welding or assembly due to excessively thin pins or stamping defects. It also prevents cracks caused by fatigue stress at the connection between the pins and the bracket body in high-frequency vibration scenarios.

[0016] In this invention, the bracket angle is adjusted by connecting the connecting column and universal joint to the connecting rod. At the same time, the LED body is powered by a fixed power supply. The LED body is connected to the circuit board. The adjustment knob can adjust the angle of the movable shaft, and the rotating shaft is used to rotate and adjust the angle of the circuit board, thus making the device highly flexible during use.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides a technical solution: a wire support for a light-emitting diode, comprising a supporting base rod 1;

[0026] The connecting component 2 includes several grooves 201, which are formed on the side surface of the supporting base rod 1. The grooves 201 are arranged in a ring array on the side surface of the supporting base rod 1. The bottom end of the supporting base rod 1 is fixedly connected to a limiting base 202. Each groove 201 is movably connected to a hinge seat 203. The hinge seat 203 is movably connected to a hinge shaft 204 via a hinge. The side surface of the hinge shaft 204 is movably connected to two hinge plates 205 via a hinge. The two hinge plates 205 are symmetrically distributed on the side surface of the hinge shaft 204. The two hinge plates 205 are movably connected to a through column 206.

[0027] Support assembly 3 includes several hinge seats 301, which are fixedly connected to the side surface of the support base rod 1. The hinge seats 301 are arranged in a circular array on the side surface of the support base rod 1. A hinge shaft 302 is movably connected inside each hinge seat 301. A connector 303 is fixedly connected to the side surface of the hinge shaft 302. The support assembly 3 and the connecting assembly 2 support the bracket. Rotating the hinge shaft 302 by the hinge seats 301 causes the hinge shaft 302 to drive the connector 303, which in turn causes the support leg 304 to extend outwards. The support is further secured by an anti-slip pad 305 that adheres to the ground. The bottom of the anti-slip pad 305 has protrusions to increase friction and stabilize the bracket. The supporting component 3 is further stabilized by the connecting component 2. The hinge plate 205 is connected to the supporting leg 304 by the through column 206. When the supporting leg 304 extends outward, the through column 206 rotates, so that the hinge plate 205 pushes the hinge seat 203 to slide in the groove 201, thereby completing the bracket deployment and support fixation, ensuring that the bracket is relatively stable during operation and avoiding vibration of the bracket. This prevents the bracket pins from being too thin or having stamping process defects, which can easily break during welding or assembly. At the same time, in high-frequency vibration scenarios, the connection between the pins and the bracket body may crack due to fatigue stress. The supporting leg 304 is fixedly connected to one side of the connecting component 303, and the bottom end of the supporting leg 304 is fixedly connected to the anti-slip pad 305.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a connecting column 4 is fixedly connected to the top of the support rod 1, a universal joint 5 is movably connected to the top of the connecting column 4, a connecting rod 6 is fixedly connected to the top of the universal joint 5, an adjusting member 7 is movably connected to the side surface of the connecting rod 6, and a top rod 8 is fixedly connected to the top of the connecting rod 6. Simultaneously, a fixed power supply 10 supplies power to the LED body 18. The LED body 18 is connected to the circuit board 13. An adjusting knob 16 can adjust the angle of the movable shaft 15, and a rotating shaft 11 is used to rotate to adjust the angle of the circuit board 13, thus giving the device high flexibility during use. A sleeve 9 is movably connected to the side surface of the top rod 8 via a sleeve connection, a fixed power supply 10 is fixedly connected to the side surface of the sleeve 9, a rotating shaft 11 is movably connected to the side surface of the top rod 8, a connecting bracket 12 is fixedly connected to the side surface of the rotating shaft 11, and a circuit board 13 is fixedly connected to the top of the connecting bracket 12.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 and Figure 6 As shown, a mounting plate 14 is fixedly connected to the top of the circuit board 13, a movable shaft 15 is fixedly connected to the top of the top rod 8, and adjustment knobs 16 are fixedly connected to both ends of the movable shaft 15. The two adjustment knobs 16 are symmetrically distributed at both ends of the movable shaft 15. A curved plate 17 is fixedly connected to the side surface of the movable shaft 15, and a light-emitting diode body 18 is fixedly connected to one side of the curved plate 17.

[0030] The method of use and advantages of this utility model: The lead wire bracket for light-emitting diodes operates as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when using the lead frame for LEDs, the frame is first supported by the connecting assembly 2 and the supporting assembly 3. The hinge shaft 302 is rotated by the hinge seat 301, causing the hinge shaft 302 to drive the connector 303, which in turn causes the support leg 304 to extend outwards. The support is then supported by an anti-slip pad 305 that adheres to the ground. The bottom of the anti-slip pad 305 has protrusions to increase friction and stabilize the frame. The supporting assembly 3 is further stabilized by the connecting assembly 2. The hinge plate 205 is connected to the support leg 304 by a through post 206. When the support leg 304 extends outwards, the through post 206 rotates, causing the hinge plate 205 to push the hinge seat 203 to slide within the groove 201. This allows the bracket to be deployed and fixed, ensuring stability during operation and preventing vibration. It also prevents breakage during welding or assembly due to thin pins or stamping defects. Furthermore, in high-frequency vibration scenarios, fatigue stress can cause cracks at the connection between the pins and the bracket body. The bracket angle is adjusted by connecting the connecting rod 6 via connecting column 4 and universal joint 5. A fixed power supply 10 powers the LED body 18, which is connected to the circuit board 13. Adjusting knob 16 adjusts the angle of the movable shaft 15, and rotating shaft 11 adjusts the angle of the circuit board 13, thus providing high flexibility during use.
