Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lighting appliances, in particular to a flashlight with an integrated battery compartment cover and power control mechanism. BACKGROUND

[0002] The current outdoor flashlight is mainly composed of a lamp head assembly, a barrel, a battery, and a tail cover. The barrel is made of conductive materials such as aluminum alloy, stainless steel, and titanium alloy, which not only serves as protection and support but also as a negative path. However, for high-power flashlights, the rated current can reach 3-5A or even higher, and using the barrel as a negative path can easily cause electric leakage, which is less safe. SUMMARY

[0003] In view of the above problems, the utility model is proposed to provide a flashlight with an integrated battery compartment cover and power control mechanism that overcomes the above problems or at least partially solves them.

[0004] The flashlight with an integrated battery compartment cover and power control mechanism includes a lamp head assembly, a barrel, a battery, a battery compartment cover, and a tail cover. The battery compartment cover and the tail cover are fixed by a connecting piece. The battery compartment cover includes a cover body, a negative spring, two negative connection lines, a positive conductive column, a first PCB board, an elastic contact assembly, and a front cover. The cover body forms a compartment for accommodating the battery. The front sealing plate part of the cover body is fixedly connected with the front cover and encloses an installation space. The first PCB board is fixed in the installation space. The positive conductive column is fixedly connected with the first PCB board, with one end extending out of the first through hole in the middle of the front cover and the other end extending into the through hole in the middle of the front sealing plate part. The positive pole of the battery arranged in the compartment contacts the end of the positive conductive column extending into the through hole in the middle of the front sealing plate part, and the negative pole of the battery contacts the negative spring extending out of the through hole in the middle of the rear sealing plate part of the cover body. The bottom of the elastic contact assembly is fixedly connected with the first PCB board, and the head thereof extends out of the second through hole of the front cover and contacts the conductive ring of the lamp head assembly. The inner wall of the compartment forms two installation grooves for installing the two negative connection lines respectively. The two ends of each negative connection line are electrically connected with the first PCB board and the second PCB board of the power control mechanism in the tail cover respectively. The negative spring is electrically connected with the second PCB board. The first PCB board forms conductive lines connecting each negative connection line with the bottom of the elastic contact assembly.

[0005] In one embodiment, the cover body forms an opening for the battery to enter the compartment. The middle part of each of the two opposite long edges of the opening is bent inwardly in a direction away from the bottom of the compartment to form a buckle part, and the outer wall of the other part of the two long edges is recessed inwardly to form a thin wall part.

[0006] In one embodiment, the elastic contact assembly includes a conductive spring and a rivet-shaped electrical contact; the second through hole is a stepped hole, and the rivet-shaped electrical contact extends out of the second through hole, and the rivet-shaped electrical contact can abut against the transverse wall of the second through hole; one end of the conductive spring abuts against the rivet-shaped electrical contact, and the other end is fixedly connected to the first PCB board.

[0007] In one embodiment, the bottom of the compartment has a marking indicating the battery installation direction.

[0008] This utility model of a flashlight with an integrated battery compartment cover and power control mechanism uses two negative terminal connecting wires installed on the inner wall of the compartment, conductive lines on the first PCB board, and elastic contact components as the negative terminal path. Compared to using the flashlight body as the negative terminal path, this method offers higher safety. The use of two parallel negative terminal connecting wires prevents power outages caused by the breakage of a single negative terminal connecting wire, thus improving product reliability.

[0024] Now referring to Figure 5 And Figure 6 , the battery compartment cover 4 includes compartment cover main body 6, negative spring 7, two negative connection line 8, positive conductive column 9, first PCB board 10, elastic contact component 11 and front cover 12.The compartment cover main body 6 forms a compartment 13 for accommodating battery 3, the front sealing plate part 14 of the compartment cover main body 6 is fixedly connected with the front cover 12 and encloses an installation space, and the first PCB board 10 is fixed in the installation space.In this embodiment, the front sealing plate part 14 and the front cover 12 are both generally disc-shaped, the circular edge of the front sealing plate part 14 abuts against the circular edge of the front cover 12, and the front sealing plate part 14 and the front cover 12 are fixedly connected by bolts.

[0025] The positive conductive column 9 is fixedly connected with the first PCB board 10, specifically, the first PCB board 10 can form a through hole for the positive conductive column 9 to pass out one end, and a gold pad can be arranged around the through hole, and the positive conductive column 9 and the first PCB board 10 are fixedly connected by welding.

[0026] One end of the positive conductive column 9 extends out of the first through hole 15 in the middle of the front cover 12, and the other end extends into the through hole in the middle of the front sealing plate part 14.The positive pole of the battery 3 arranged in the compartment 13 contacts one end of the positive conductive column 9 extending into the through hole in the middle of the front sealing plate part 14, and the negative pole of the battery 3 contacts the negative spring 7 passing out of the through hole in the middle of the rear sealing plate part 16 of the compartment cover main body 6.

[0030] The batteries used in outdoor flashlights are mostly rechargeable lithium batteries, and the reverse connection of the positive and negative electrodes is a serious mistake. Lithium batteries may have a violent electrochemical reaction under reverse current, rapidly heat up in a short time, and even have safety hazards such as bulging and fire. The bottom of the compartment 13 can be provided with a mark indicating the installation direction of the battery, so as to reduce the probability of installation error of the positive and negative electrodes of the battery.

[0031] The embodiment uses two negative electrode connecting wires mounted on the inner wall of the compartment, a conductive circuit of the first PCB board, and an elastic contact assembly as the negative electrode passage, which is safer than the way of using a barrel as the negative electrode passage. The use of two negative electrode connecting wires in parallel can prevent power failure caused by the breakage of a single negative electrode connecting wire, thereby improving the reliability of the product.
