[0030] like Figures 1-8 As shown, a circuit board mounting structure for a flashlight includes a mounting bracket 1 and a circuit board assembly. The mounting bracket 1 is located between the battery 2 and the lampshade 3. The mounting bracket 1 has a placement slot 11 for placing the circuit board assembly, and the bottom of the placement slot 11 is open. The top of the placement slot 11 itself has an opening to allow the circuit board assembly to enter and expose electronic components, and the bottom of the placement slot 11 has an opening to expose the electronic components.

[0031] Meanwhile, the circuit board assembly includes circuit board 4, circuit board 5 and circuit board 6, wherein the battery 2 is electrically connected to circuit board 6, and one of circuit board 4 and circuit board 2 is provided with a charging head 41, and the other is provided with a switch 51. Circuit board 4 and circuit board 2 are both soldered onto circuit board 6, and the placement slot 11 has two protrusions 12 inside.

[0032] Therefore, in actual use, the circuit board assembly is placed in the placement slot 11. At this time, the first circuit board 4 is located at the top opening of the placement slot 11 and is connected to the boss 12 by fasteners, i.e. screws, so as to prevent the circuit board assembly from falling out of the placement slot 11. The second circuit board 5 is located between the first circuit board 4 and the mounting bracket 1.

[0033] Therefore, by soldering circuit board 4 and circuit board 5 onto circuit board 6, the three boards are integrated into a whole and can be installed together. This is more convenient than installing them separately, and while installing them separately requires at least six screws, this application only requires two, thus saving time and effort.

[0034] The battery 2 is protected by a casing 10. The battery 2 is electrically connected to the circuit board 6 using a spring, as springs are conductive and their elasticity ensures a more stable connection. The mounting structure at the other end of the battery 2 is not the focus of this text and is existing technology, so it will not be described in detail. The casing 7 has an opening above the charging head 41 and a silicone cover 42 for protection. The circuit board 5 has a clearance groove 52 corresponding to the protrusion 12, and a pressing plate 53 is located below the switch 51. Pressing the pressing plate 53 activates the switch 51.

[0035] like Figures 4-7 As shown, in order to make the connection between the mounting bracket 1 and the circuit board assembly more stable, a protrusion 13 is provided at the end of the mounting bracket 1, and the circuit board 6 is located on the outside of this end of the mounting bracket 1 and has a hole 61 corresponding to the protrusion 13.

At this time, the circuit board 36 is located outside the mounting bracket 1, and the clip 54 is located in the elongated hole 14. Then, the circuit board assembly is moved towards the lampshade 3 until the protrusion 13 is located in the hole 61 and the clip 54 is matched with the slot 15, thereby realizing the installation. Then, it is tightened by fasteners, i.e., screws.

[0038] Furthermore, the inner wall of the placement groove 11 is provided with a step 16, and the step 16 and the upper surface of the boss 12 are on the same horizontal plane, and the bottom of the circuit board 4 is located on the step 16, thereby limiting the position of the circuit board 4 and allowing the circuit board 4 to contact the boss 12.

The housing 7 is connected to a cover 8 at one end near the mounting bracket 1, and the lampshade 3 is located between the cover 8 and the mounting bracket 1. The cover 8 and the housing 7 are connected by threads.

[0040] Meanwhile, the mounting bracket 1 and the lampshade 3 are connected by threads, and the end of the lampshade 3 connected to the mounting bracket 1 is provided with a lamp bead 31, and a sealing ring 32 is provided on the outer side of this end. The lamp bead 31 is electrically connected to the circuit board assembly. The other end of the lampshade 3 is provided with a transparent plate 33, and a sealing ring 34 is provided between the transparent plate 33 and the housing 7. The transparent plate 33 is located between the cover 8 and the lampshade 3, and the cover 8 has an opening corresponding to the transparent plate 33.

[0041] The LED bead 31 is electrically connected to the circuit board assembly; that is, the LED bead 31 is mounted on the circuit board and can be electrically connected to the circuit board assembly via wires. Meanwhile, the sealing ring serves to seal and prevent the ingress of external substances.

[0042] like Figure 8 As shown, the structure between the mounting bracket 1 and the housing 7 is as follows: First, the housing 7 is also included, and the mounting bracket 1, battery 2 and lampshade 3 are all located inside the housing 7. The mounting bracket 1 and the housing 7 are connected by fasteners, i.e. screws. The inner wall of the housing 7 is provided with a protruding plate 71, and the protruding plate 71 abuts against the mounting bracket 1 to restrict the position of the mounting bracket 1.
