[0018] The upper shell (11) of the main body (1) has a first storage position (111) embedded in the sidewall for fixing a magnet (112), and the inner bottom surface of the cover body (21) of the bottom cover (2) has a second storage position (211) for fixing another magnet (112), and the two are connected through an elastic hinge structure. When magnetic attraction is needed, the magnet (112) of the main body (1) is attracted to a metal surface (such as the door of a refrigerator), and at the same time the magnet (112) of the bottom cover (2) enhances the attraction; when clamping is needed, press the bottom cover (2), the elastic hinge structure drives the bottom cover (22) to expand outward, and the friction between the anti-skid pad (221) and the clamping surface (such as a wooden board or a table edge) fixes the lamp, realizing double-mode quick switching. The magnets (112) are respectively arranged in the storage positions of the main body and the bottom cover to realize complementary fixing in double modes. The anti-skid pad (221) and the magnet (112) cooperate to improve the clamping stability.

[0019] See Figures 1 to 5 In another embodiment, the elastic hinge structure includes a rivet (3) and a spring (4), the bottom cover (2) is hinged to the upper shell (11) through the rivet (3), and the spring (4) is arranged at the hinge shaft of the rivet (3).

[0020] The rivet (3) penetrates the hinge hole of the upper shell (11) and the hinge part of the bottom cover (2), and the spring (4) is sleeved on the shaft part of the rivet (3) and is pre-compressed. When the bottom cover (2) is pressed, the spring (4) is compressed, and the bottom cover (2) rotates and expands around the axis of the rivet (3); when it is released, the restoring force of the spring (4) drives the bottom cover (2) to reset and close. This structure supports clamping thickness of 0.5-15mm, and the spring (4) is made of 316 stainless steel, which is corrosion-resistant and has a service life of more than 100,000 times. The spring (4) provides uniform elastic pressure, which is suitable for different clamping thicknesses. The rigid connection of the rivet (3) ensures the stability of the rotating structure.

[0021] See Figures 1 to 5 In another embodiment, a light diffusion plate (14) is arranged between the lighting surface shell (13) and the lower shell (12), and a waterproof ring (16) is sleeved between the light diffusion plate (14) and the light guide part (151) of the PCBA lamp plate assembly (15). The light diffusion plate (14) is made of frosted acrylic material, covers the light guide part (151) of the PCBA lamp plate (15), and the edge is sealed and connected with the light guide part (151) through the waterproof ring (16). After the light is emitted from the light guide part (151), it is uniformly scattered to the whole area of the lighting surface shell (13) through the light diffusion plate (14), and the waterproof ring (16) is made of silicone material to prevent water vapor from entering the inside of the lamp plate, meeting the IP54 protection standard. The light diffusion plate (14) eliminates the problem of local overexposure and improves the uniformity of illumination. The waterproof ring (16) simultaneously realizes the functions of sealing and optical gap filling.

[0022] See Figures 1 to 5In another embodiment, the main body (1) is also provided with a key structure (5), which comprises a support frame (51), a PCBA key plate (52), a light guide (53) and a key group plate (54), both ends of the support frame (51) are provided with clamping grooves (511), the edges of the light guide (53) are clamped into the clamping grooves (511), the PCBA key plate (52) is fixed to the inner side of the upper shell (11), and the key group plate (54) is clamped with the matching groove (531) of the light guide (53).

[0023] The clamping grooves (511) of the support frame (51) are buckled into the edges of the light guide (53), the key group plate (54) is fixed in the matching groove (531) of the light guide (53) by screws, and the PCBA key plate (52) is attached to the inner side of the upper shell (11). When assembling, the key assembly is inserted into the mounting groove (17) formed by the upper shell (11) and the lower shell (12), the light transmission part of the light guide (53) is aligned with the opening of the illumination face shell (13), and when the touch operation is performed, the key group plate (54) presses to trigger the micro switch of the PCBA key plate (52). The light guide (53) has the functions of key guiding and status indicator. The nested design of the clamping grooves (511) and the matching grooves (531) realizes quick assembly of the key assembly. The light guide (53) integrates light guiding and signal triggering double-layer functions, simplifying the structure.

[0024] See Figures 1 to 5 In another embodiment, the upper shell (11) and the lower shell (12) form a mounting groove (17) when buckled, and the support frame (51) is bonded in the mounting groove (17).

[0025] After the upper shell (11) and the lower shell (12) are buckled, the edges form a mounting groove (17) with a rectangular cross section, and the depth is 2.5mm. The bottom surface of the support frame (51) is coated with high-temperature resistant epoxy glue, which is cured after being embedded in the mounting groove (17), and the bonding area covers more than 85% of the bottom surface of the support frame (51). This design eliminates the traditional screw fixing process, improves the assembly efficiency by 30%, and avoids damage to the appearance of the lamp by screws. The bonded mounting groove (17) provides stable support and simplifies the production line process.

[0026] See Figures 1 to 5 In another embodiment, the depth of the first compartment (111) and the second compartment (211) is 90%-95% of the thickness of the built-in magnet (112).

[0027] Taking the thickness of the magnet (112) as an example, the depth of the first position (111) and the second position (211) is designed to be 2.7-2.85mm. After embedding, the back surface of the magnet (112) is flush with the opening of the position or slightly lower than 0.3mm, preventing scratches caused by protrusion. Tests show that the loss of magnetic attraction is less than 5%, and the magnet has no risk of falling off in a strong vibration environment. The depth of the position is accurately matched with the thickness of the magnet, ensuring the balance between the adsorption force and the structural safety.
