[0044] Among them, the flexible board body 1 is provided with a rubber rod, a rubber protective plate, a rubber limit rod, etc. The rubber rod, the rubber protective plate, the rubber limit rod, etc. are existing public patents: 202220116632.4 A prior art in a flexible circuit board for a vehicle-mounted LED lamp, which will not be described in detail here;

[0045] Among them, four fixing grooves 3 are arranged on the flexible board body 1;

[0046] Among them, a protective block 4 is fixedly connected in the fixing groove 3;

[0047] Among them, a protective mechanism is arranged on the protective block 4, and the protective mechanism includes an installation groove 5, a installation block 6, a sliding groove 7, a sliding block 8, a support plate 9, a fixing spring 10, a support groove 11, a rubber column 12, a conical cover 13, a bottom groove 14, a support spring 15, and a protective plate 16.

[0048] Furthermore, a plurality of rubber cylinders 12 are fixedly connected to the upper surface of the flexible board 1.

[0049] Wherein, the mounting groove 5 is provided on the upper surface of the protection block 4;

[0050] Wherein, the mounting block 6 is fixedly connected to the lower surface of the protection block 4;

[0051] The lower surface of the mounting block 6 and the lower surface of the flexible board body 1 are in the same plane.

[0052] Further, the sliding groove 7 is provided on the outer surface of the mounting block 6;

[0053] Wherein, the mounting block 6 is adapted to the mounting groove 5;

[0054] The support groove 11 is provided on the outer surface of the protection block 4 , and the support groove 11 is communicated with the inside of the installation groove 5 .

[0055] Further, the sliding block 8 is slidably connected in the supporting groove 11;

[0056] The outer surface of the sliding block 8 close to the protective block 4 slides and extends into the mounting groove 5, and the upper surface of the sliding block 8 extending into the mounting groove 5 is an inclined surface;

[0057] The outer surface of one side of the sliding block 8 away from the protective block 4 extends out of the protective block 4;

[0058] The support plate 9 is fixedly connected to the outer surface of the sliding block 8 on one side away from the protection block 4 .

[0059] Further, two fixing springs 10 are fixedly connected between the support plate 9 and the protection block 4;

[0060] Wherein, the sliding block 8 is adapted to be connected with the sliding groove 7;

[0061] Wherein, the conical cover 13 is fixedly connected to the upper surface of the rubber cylinder 12;

[0066] The upper surface of the protection plate 16 and the upper surface of the conical cover 13 are in the same plane.

[0067] Furthermore, stacking multiple flexible board bodies 1 together during transportation is an incorrect way to place the circuit boards. The correct way to use them is to slide the four mounting blocks 6 on the bottom wall of one flexible board body 1 into the mounting groove 5 on another flexible board body 1. In the process of sliding the mounting block 6 into the mounting groove 5, the lower surface of the mounting block 6 gives a thrust to the inclined surface of the sliding block 8, pushing the sliding block 8 to move out of the mounting groove 5. In this process, the fixing spring 10 is stretched. When the lower surface of the mounting block 6 contacts and fits with the bottom wall of the mounting groove 5, the sliding groove 7 and the bottom wall of the supporting groove 11 are in the same plane. At this time, under the action of the released elastic force of the fixing spring 10, the sliding block 8 is pushed to slide into the sliding groove 7, and then the sliding block 8 connects the upper flexible board body 1 with the lower flexible board body 1. The board body 1 is fixed together by the protective block 4 and the mounting block 6, so that the protective block 4 on the lower flexible board body 1 and the mounting block 6 on the upper flexible board body 1 cannot be separated, thereby realizing the fixation of the two flexible board bodies 1. At the same time, because the protective block 4 itself has a height, and the height of the protective block 4 is higher than the height of the LED lamp bead 2, the bolts on the bottom flexible board body 1 are fixed to a hard board body, thereby isolating the upper flexible board body 1 from the lower flexible board body 1. By aligning the mounting block 6 on the upper flexible board body 1 with the mounting groove 5 on the lower flexible board body 1, the isolation and protection of the flexible board body 1 can be achieved. The operation is convenient and there is no need to rotate the bolts. It saves manpower while improving efficiency, thereby increasing the practicality of the flexible circuit board for automotive LED lamp modules.

[0068] Furthermore, when it is necessary to disassemble multiple isolated flexible board bodies 1, it is only necessary to pull the support plate 9 and simultaneously drive the sliding block 8 to move out of the sliding groove 7. The operation is convenient and there is no need to rotate the bolts, which saves manpower and improves efficiency, thereby increasing the practicality of the flexible circuit board for the automotive LED lamp module.

[0069] Furthermore, when the mounting block 6 on the upper flexible board body 1 is aligned with the mounting groove 5 on the lower flexible board body 1, the upper surface of the protective plate 16 and the upper surface of the conical cover 13 are in contact with and fit with the lower surface of the upper flexible board body 1. When the upper side of the flexible board body 1 is squeezed, the rubber conical cover 13 and the support spring 15 can buffer the squeezing force to prevent the LED lamp beads 2 from being squeezed, thereby protecting the LED lamp beads 2 and preventing the LED lamp beads 2 from being squeezed and damaged, thereby increasing the practicality of the flexible circuit board for the automotive LED lamp module.

[0070] Furthermore, the protective plate 16 can prevent the upper end of the supporting spring 15 from being too sharp and piercing the flexible board body, thereby increasing the practicality of the flexible circuit board for the automotive LED lamp module.

[0071] Furthermore, in this solution, the rubber column 12, the conical cover 13 and the protective plate 16 are all made of rubber material.

[0072] Working principle: When the device is used, multiple flexible board bodies 1 are stacked together during transportation, which is an incorrect way to place the circuit boards. The correct way to use it is to slide the four mounting blocks 6 on the bottom wall of a flexible board body 1 into the mounting groove 5 on another flexible board body 1. In the process of sliding the mounting block 6 into the mounting groove 5, the lower surface of the mounting block 6 gives a thrust to the inclined surface of the sliding block 8, pushing the sliding block 8 to move out of the mounting groove 5. In this process, the fixing spring 10 is stretched. When the lower surface of the mounting block 6 contacts and fits with the bottom wall of the mounting groove 5, the sliding groove 7 and the bottom wall of the supporting groove 11 are in the same plane. At this time, under the action of the released elastic force of the fixing spring 10, the sliding block 8 is pushed to slide into the sliding groove 7, and then the sliding block 8 connects the upper flexible board body 1 with The flexible board body 1 on the lower side is fixed together by the protective block 4 and the mounting block 6, so that the protective block 4 on the lower flexible board body 1 and the mounting block 6 on the upper flexible board body 1 cannot be separated, thereby realizing the fixation of the two flexible board bodies 1. At the same time, because the protective block 4 itself has a height, and the height of the protective block 4 is higher than the height of the LED lamp bead 2, the bolts on the bottom flexible board body 1 are fixed to a hard plate body, thereby isolating the upper flexible board body 1 from the lower flexible board body 1. By aligning the mounting block 6 on the upper flexible board body 1 with the mounting groove 5 on the lower flexible board body 1, the isolation and protection of the flexible board body 1 can be achieved. The operation is convenient and there is no need to rotate the bolts. It saves manpower while improving efficiency, thereby increasing the practicality of the flexible circuit board for automotive LED lamp modules.
