Description

Technical Field

[0002] Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can be called printed circuit boards or printed circuit boards. Circuit boards are also called flexible circuit boards. Flexible circuit boards are made of polyimide or polyester film as a substrate and are highly reliable and extremely flexible printed circuit boards. Therefore, they have been widely used in the field of new energy vehicle LED lights.

[0003] Chinese patent publication number CN211084015U discloses a flexible circuit board for new energy vehicle LED lights. The board comprises a circuit board body, a mounting plate disposed below the board body, and through-holes formed near the top and left sides of the board body and the mounting plate. Threaded tubes are disposed between the board body and the mounting plate, near the left and right sides, respectively. The top and bottom ends of the threaded tubes extend into the two vertical through-holes, respectively. Nuts are disposed above the threaded tubes. First soft pressing plates are fixedly connected to the tops of the threaded tubes, near the left and right sides, respectively. Second soft pressing plates are fixedly connected to the tops of the two first soft pressing plates. The tops of the second soft pressing plates are fixedly connected to the bottoms of the nuts.

[0004] The flexible circuit board for new energy vehicle LED lights involved in the above-mentioned patent is installed on the top of the mounting plate by pressing and positioning. However, this installation method causes the bottom of the circuit board to fit tightly with the top of the mounting plate, resulting in a weak heat dissipation effect. When the automotive LED lights are used for a long time, a lot of heat will be generated. If the heat is not dissipated in time, the circuit board will be easily damaged.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-4The utility model provides a flexible circuit board for new energy vehicle LED lamps, including a circuit board body 1, a top cover 2 and a base 3 are respectively provided on the upper and lower sides of the circuit board body 1, and support frames 4 are fixedly installed on both sides of the bottom of the inner cavity of the base 3. The bottom of the circuit board body 1 is in contact with the top of the support frame 4, and a plurality of groups of partition frames 5 are fixedly installed on the back of the inner cavity of the base 3. The back of the circuit board body 1 is in contact with the front of the partition frames 5. A tightening component is provided on both sides of the inner cavity of the top cover 2, and the circuit board body 1 is tightly fixed to the inner cavity of the base 3 through the tightening component. The tightening component includes a tightening plate 10 provided on both sides of the bottom of the top cover 2, and a compression spring 11 is fixedly installed on the top of the tightening plate 10. The top of the compression spring 11 is fixedly connected to the top of the inner cavity of the top cover 2.

[0022] In this embodiment, the circuit board body 1 is installed between the base 3 and the top cover 2. The base 3 and the top cover 2 can protect the circuit board body 1. The top of the circuit board body 1 will not contact the top cover 2, and the back and bottom of the circuit board will not contact the base 3 through the use of the abutment plate 10, the spacer 5 and the support frame 4. This non-contact creates space for heat dissipation. The arrangement of the abutment assembly can firmly fix the circuit board body 1 to the inner cavity of the base 3 when the top cover 2 is locked and fixed to the base 3. In addition, in this embodiment, a connection slot (not shown) is provided on the back of the top cover 2 for connecting the wiring harness to the circuit board body 1.

[0023] Preferably, a locking assembly is provided between the top cover 2 and the base 3, and the top cover 2 is locked and fixed to the top of the base 3 through the locking assembly. The locking assembly includes a first locking column 12 fixedly installed at the four corners of the top cover 2 and a second locking column 13 installed at the four corners of the base 3. The top of the first locking column 12 is threadedly connected to a locking rod 14, and the top of the second locking column 13 is provided with a locking hole 15 that is compatible with the locking rod 14. The bottom end of the locking rod 14 passes through the first locking column 12 and extends to the bottom of the first locking column 12 and is threadedly connected to the inner wall of the locking hole 15. The top of the first locking column 12 is provided with a countersunk hole 16 that is compatible with the top of the locking rod 14.

[0024] By setting the locking assembly, the top cover 2 can be locked and fixed to the top of the base 3. After placing the circuit board body 1 in the inner cavity of the base 3, the user can cover the top cover 2 on the top of the base 3, and then tighten the locking rod 14. The rotation of the locking rod 14 will cause its bottom end to pass through the first locking column 12 and be threadedly connected to the locking hole 15 at the top of the second locking column 13, thereby locking and fixing the top cover 2 to the top of the base 3. By setting the countersunk hole 16, the top end of the locking rod 14 will be hidden in the inner cavity of the countersunk hole 16 when it is in the locked state, so as to improve the flatness of the top of the top cover 2.

[0025] It is worth noting that a heat dissipation component for improving the air circulation on the surface of the circuit board body 1 is provided between the top cover 2 and the base 3. The heat dissipation component includes an air inlet component and an air exhaust component. The air inlet component is installed on the top of the top cover 2, and the exhaust component is provided on the front of the base 3. The air inlet component includes a cooling fan 6 provided on the top of the top cover 2. An air inlet slot 7 is provided on the top of the top cover 2 and corresponding to the cooling fan 6. The exhaust component includes an exhaust slot 8 provided on the front of the base 3, and a filter 9 is fixedly installed in the inner cavity of the exhaust slot 8.

[0026] Through the configuration of the heat dissipation assembly, when the LED lamp is operating, the cooling fan 6 draws cooler air from the outside into the interior of the top cover 2 and base 3. The cooler air then flows through the top and bottom of the circuit board and is discharged to the outside through the exhaust slots 8, thereby cooling the surface of the circuit board body 1. The provision of the filter 9 prevents external dust from entering the interior of the base 3 and top cover 2 through the exhaust slots 8 and adhering to the surface of the circuit board body 1.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
