Description

Technical Field

[0001] This utility model relates to the field of lighting equipment structure technology, specifically to a multifunctional flashlight housing structure, which is particularly suitable for flashlight products with high requirements for integrated display, control and protection performance. Background Technology

[0002] Most flashlights on the market currently feature traditional metal casings with protruding buttons that are easily damaged by impacts. The display windows are often fixed with adhesive, resulting in poor sealing and making maintenance difficult once the structure loosens. The threaded connections on the casing have low protection levels, making them susceptible to water and dust ingress during outdoor use, affecting their lifespan. Furthermore, traditional casings often lack dedicated positioning designs for the display screen and button components, leading to internal structural loosening or misalignment, causing problems such as unresponsive operation and unclear display. Therefore, there is an urgent need for a multi-functional flashlight casing structure with optimized structure, reliable assembly, and excellent protective performance to meet the needs of outdoor and industrial applications. Utility Model Content

The housing is provided with a button mounting cavity, a display window, and protective components.

[0005] Preferably, the button mounting cavity has a recessed structure, and the button is fixedly connected to the housing by a limiting ring and a snap-fit ​​flange;

[0006] Preferably, the display window has a stepped slot structure, the cover plate is interference-fitted with it, and it is waterproof and dustproof through a sealing ring;

[0007] Preferably, a silicone waterproof ring is provided at the threaded interface to effectively improve the sealing performance of the housing;

[0008] Preferably, the outer surface of the housing is provided with multiple heat dissipation grooves to improve the heat dissipation efficiency during equipment operation;

[0009] Preferably, the housing is made of anodized aluminum alloy, which balances strength, corrosion resistance and aesthetics. Attached Figure Description

[0023] Implementation Method 1: This implementation method provides a multifunctional flashlight housing structure, including a cylindrical housing. One end of the cylindrical housing is provided with a threaded interface for tight connection with a light source module. The other end of the housing is provided with a rear cover, which is connected to the housing by a thread and secured with a buckle to ensure the overall structural stability and sealing. The limiting buckle structure is a symmetrically arranged tongue-type buckle located on both sides of the outer edge of the rear cover (7). It cooperates with the groove on the inner wall of the cylindrical housing (1) to achieve locking and positioning after being screwed into the thread. The thickness of the tongue is 1mm to 5mm, and the groove is an open groove structure with a depth of 1.2mm to 1.8mm. The structural design allows for automatic engagement and positioning during tightening, while also having an anti-loosening function, facilitating repeated disassembly and assembly, and ensuring high reliability. This structure can be formed by injection molding or integral milling and is suitable for metal or plastic materials.

[0024] Implementation Method 2: The cylindrical shell has a button mounting cavity in the middle. The button mounting cavity is a recessed structure with a circular or elliptical cross-section and a depth of 2mm to 4mm, which can be adjusted according to the button structure size. The button mounting cavity is formed by vertical drilling and is integrally formed with the shell body. The inner side wall is provided with an annular limiting groove. After the button is installed, it is fixed by the limiting structure (including the limiting ring and the snap-fit ​​flange), which avoids the problem of the button falling off due to external force. The limiting structure (8) includes the embedded limiting ring and the snap-fit ​​flange. The two work together to realize the axial positioning and anti-dislodgement function of the button, effectively improving the service life and assembly stability. The limiting ring is an annular boss structure, radially positioned in the middle section of the inner wall of the button mounting cavity, with a thickness of 0.5mm to 1mm, used to limit the button insertion depth. The snap-fit ​​flange is located outside the limiting ring, spaced 0.2mm apart to form a fitting groove. The bottom edge of the button has corresponding snap teeth, which engage with the snap-fit ​​flange during assembly to ensure the button remains stable in both the axial and radial directions. This structure is easy to mold and has high reliability. The shape of the annular groove and snap teeth can be adjusted according to specific dimensional requirements. The shape or processing method can be adjusted according to specific circumstances.

[0025] Implementation Method 3: The housing is equipped with a display window, which is rectangular in structure with stepped slots along the edges. A transparent cover plate is embedded in the slots and interference-fits with them, ensuring both the safety of the display screen and dust and water resistance. The display window is positioned to fit snugly with the housing structure, facilitating rapid assembly of standard display modules. The display components are fixed to the limiting brackets via guide rails on the inner wall of the housing. These guide rails are symmetrically distributed on both sides of the inner wall of the display window. For OLED or LCD modules with a thickness of 0.8mm-1.0mm, the bracket height and guide rail spacing can be adjusted according to the specific module size. OLED modules are typically flexible structures with ribbon cables located on the side of the module. A ribbon cable channel with a width of 3mm-1mm is provided on the inner side of the housing. The display components, through the aforementioned guide rails and limiting brackets, achieve stable installation and anti-vibration positioning for modules with different structures, adapting to display units of different sizes and thicknesses, improving overall compatibility and assembly reliability. The stepped slot structure includes two steps. The first step guides the positioning of the transparent cover plate, and the inner diameter of the second step is 0.2mm-1mm smaller than the outer diameter of the cover plate. The edges of the step difference are rounded to avoid stress concentration. This structure can be combined with a sealing ring to achieve a protection level of IPX5 or higher, providing good airtightness and vibration resistance. It can be adjusted according to the specific application environment.

[0026] Implementation Method 4: A waterproof ring is provided at the threaded interface. The waterproof ring is made of silicone material and is installed in a special groove on the outer ring of the interface. It effectively prevents moisture and dust from entering the shell and improves the overall IP protection level of the flashlight.

[0027] Implementation Method 5: The outer surface of the cylindrical shell is provided with multiple evenly distributed heat dissipation grooves. These grooves increase the heat dissipation area, helping to quickly dissipate internal heat, making it suitable for use in scenarios involving long-term lighting or high-brightness modes. Preferably, the number of heat dissipation grooves is 6 to 10, evenly distributed along the axial direction of the shell, with a depth of 0.8 mm to 1.2 mm and a length covering the middle section of the shell (accounting for 40% to 60% of the total length of the shell), to balance thermal conductivity and structural strength. The heat dissipation grooves can be processed by milling or injection molding, and the specific dimensions can be adjusted according to the overall thermal load design.

[0028] Implementation Method Six: The shell material is anodized aluminum alloy, which has strong corrosion resistance and mechanical strength. At the same time, its surface treatment process gives the shell better aesthetics and durability. The color and spraying method can be adjusted according to specific circumstances to meet the needs of different brands.
