Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a lighting device. Background Technology

[0002] A flashlight is a common handheld electronic lighting tool. Most flat flashlights on the market have a push-button cover at the tail end of the flashlight shell, that is, the end facing away from the light body. This cover controls the flashlight's on / off state and allows switching between modes such as light intensity and wavelength, thereby controlling the final illumination effect.

[0003] In existing technology, flashlights have indicator lights on their bodies to display the battery level and charging status. These indicator lights are typically located on the side of the body. This arrangement complicates the design, requiring custom slots and perforations on the side. Furthermore, side-mounted indicator lights offer poor waterproofing; prolonged exposure to humid environments allows moisture to seep into the indicator lights through the slots, affecting their reliability and stability. Utility Model Content

[0004] The purpose of this utility model is to provide a lighting device with a reasonable layout of the indicator light group and good and reliable waterproof performance.

[0005] To achieve this objective, the present invention adopts the following technical solution:

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] This embodiment provides a lighting device. (Refer to...) Figures 1 to 4 As shown, the lighting device includes a cylindrical body 1, a soft cap 2, and a pressing cover 3. The first end of the cylindrical body 1 has a lighting element 101, and the second end of the cylindrical body 1 has a mounting groove 11. The mounting groove 11 contains a PCB board 12 electrically connected to the lighting element 101, and the PCB board 12 has an indicator light group 121. The soft cap 2 is located in the mounting groove 11 and covers the PCB board 12. The soft cap 2 has a light-transmitting hole 21 corresponding to the indicator light group 121. The pressing cover 3 is movably covered on the mounting groove 11. The pressing cover 3 has a transparent light-transmitting plug 31 corresponding to the light-transmitting hole 21. Both the light-transmitting hole 21 and the transparent light-transmitting plug 31 are used to transmit the light emitted by the indicator light group 121.

[0034] In this embodiment, the indicator light group 121 is located in the mounting groove 11 at the end of the cylinder 1 for mounting the PCB board 12. The arrangement of the indicator light group 121 has been optimized to avoid additional openings in the side of the cylinder 1, resulting in a simple structure and reasonable layout. The soft cap 2 has a light-transmitting hole 21, and the pressing cover 3 has a transparent light-transmitting plug 31. The light-transmitting hole 21 and the transparent light-transmitting plug 31 correspond to the indicator light group 121. The light emitted by the indicator light group 121 can be transmitted to the outside through the light-transmitting hole 21 and the transparent light-transmitting plug 31 for the user to observe, thereby reliably performing the indicating function of the indicator light group 121. In addition, the soft cap 2 is located in the mounting groove 11 and covers the PCB board 12. A sealing structure can be formed between the soft cap 2 and the PCB board 12, as well as between the pressing cover 3 and the soft cap 2, thereby ensuring a reliable seal within the mounting groove 11, providing reliable waterproof performance, and ensuring the reliable and stable operation of the PCB board 12 and the indicator light group 121, making it highly practical.

[0035] For example, the indicator light group 121 can indicate the power level and charging status of the lighting device by flashing different colored lights.

[0036] In this embodiment, a pressing head 32 is provided on the side of the pressing cover 3 facing the mounting groove 11. The pressing head 32 is used to press the soft cap 2 against the PCB board 12. The pressing head 32 is provided to press the soft cap 2 tightly when the pressing cover 3 is closed, ensuring the position of the soft cap 2 is stable, preventing the soft cap 2 from moving, and ensuring reliable sealing performance.

[0037] Specifically, a sealed cavity is formed between the soft cap 2, the PCB board 12, and the wall of the mounting groove 11. Specifically, the soft cap 2 is pressed tightly against the wall of the mounting groove 11, so that a sealed cavity is formed between the soft cap 2, the PCB board 12, and the wall of the mounting groove 11, thus sealing the gap between the outer edge of the soft cap 2 and the wall of the mounting groove 11, further ensuring the waterproof performance inside the mounting groove 11.

[0038] In this embodiment, the pressing cover 3 is provided with a hinge shaft, and the pressing cover 3 is hinged to the second end of the cylinder 1 through the hinge shaft. The pressing cover 3 can rotate relative to the cylinder 1 through the hinge shaft, so that the pressing cover 3 has a closed state and an outward flip state. Specifically, the second end of the cylinder 1 has hinge holes on both sides of the groove wall opposite to the mounting groove 11, and the two opposite ends of the hinge shaft pass through the hinge holes and are rotatably connected to the hinge holes.

[0039] In this embodiment, ball-head plungers 33 are provided on both opposite sides of the press cover 3. The ball-head plungers 33 are adapted to abut against the opposite side walls of the mounting groove 11 when the press cover 3 is flipped outward around the hinge axis, so that the press cover 3 is kept in the flipped-out state. The ball-head plungers 33 can support the opposite side walls of the mounting groove 11 when the press cover 3 is flipped outward around the hinge axis, thereby keeping the press cover 3 in the flipped-out state.

[0040] Specifically, when the press cover 3 is kept in the outward flipped state, the transparent light-transmitting plug 31 is opened, and the light generated by the indicator light group 121 of the PCB board 12 is transmitted through the light-transmitting hole 21.

[0041] Specifically, when the press cover 3 is in the closed state, the pressing head 32 presses against the soft cap 2, the soft cap 2 deforms and generates a force F1 towards the press cover 3. At this time, the ball plunger 33 is located in the mounting groove 11, deforms and abuts against the inner wall of the mounting groove 11. The ball plunger 33 is squeezed and generates a downward component force F2. F1 and F2 are balanced, so that the press cover 3 is in a closed and flat state.

[0042] In this embodiment, the pressing cover 3 has receiving grooves 331 on both opposite sides, and the ball plunger 33 is partially inserted into the receiving groove 331. Specifically, when the pressing cover 3 is in the closed state, the ball plunger 33 is located in the corresponding receiving groove 331, and deforms to abut against the inner wall of the receiving groove 331.

[0043] Optionally, the ball plunger 33 can be made of an elastic material, such as rubber, which is inexpensive and easy to manufacture.

[0044] In this embodiment, the PCB board 12 is provided with a USB port, and the soft cap 2 has a through hole 22 that is directly opposite the USB port. In this embodiment, when the pressing cover 3 is flipped outward around the hinge axis and kept in the flipped-out state, the USB port is exposed through the through hole 22, and an external USB plug can pass through the through hole 22 and be plugged into the USB port.

[0045] In this embodiment, the soft cap 2 is made of natural-colored high-transparency soft rubber. After the surface is painted with a light-shielding coating, the light-transmitting holes 21 are laser-engraved or otherwise treated to remove the light-shielding coating layer to achieve the light-transmitting effect.

[0046] Specifically, a light-transmitting element 211 is provided on the light-transmitting hole 21. The light-transmitting element 211 may be made of a transparent material.

[0047] In this embodiment, the pressing cover 3 has an insertion hole 34, and the transparent light-transmitting plug 31 is inserted into the insertion hole 34. The transparent light-transmitting plug 31 and the insertion hole 34 are interference-fitted.

[0048] The lighting device provided in this embodiment can be a flashlight or other types of lighting devices; this application does not impose any further limitations.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
