In this embodiment, the fourth waterproof sealing ring 2215 is a waterproof double-sided adhesive tape disposed between the upper shell 221 and the outer cover 222, which on one hand serves to fixedly connect the upper shell 221 and the outer cover 222, and on the other hand, can also achieve a waterproof effect between the upper shell 221 and the outer cover 222, so as to prevent external moisture and dust from entering the upper shell 221 from the connection between the upper shell 221 and the outer cover 222, which may cause erosion to the fisheye lens 21.

In the modular panoramic lens 100 provided by the utility model, four waterproof sealing designs are sequentially arranged from outside to inside, so that the waterproof requirement of the whole panoramic lens 100 can be met. In the front housing assembly 22 of the panoramic lens 100, a fourth waterproof sealing ring 2215 is disposed between the outer cover 222 and the upper housing 221, and a second waterproof sealing ring 118 is disposed between the upper housing 221 and the metal frame 11. This fourth waterproof sealing ring 2215 and second waterproof sealing ring 118 all are the structure that adopts waterproof double faced adhesive tape, when playing to prevent steam and getting into the gap, can also compromise the effect of connecting two parts simultaneously. Meanwhile, the upper shell 221 and the metal frame 11 are fixedly connected, a first waterproof sealing ring 2216 is arranged in the second mounting hole 2213C, and a third waterproof sealing ring 2214 is arranged between the upper shell 221 and the fisheye lens 21. This third watertight sealing ring 2214 and first watertight sealing ring 2216 all are the material that adopts the silica gel elasticity flexible glue, through the locking of connecting piece and fisheye lens 21 fixed, the compression sealing ring to play the waterproof sealing effect to setting up the department.

The two lens modules 20 in the modularized panoramic lens 100 are symmetrically arranged along the center, are compactly arranged, fully utilize the internal space, and distribute the vertical circuit boards 211 of the main heat dissipation parts of the two lens modules 20 on two sides of the middle frame component 10, and the vertical circuit boards 211 are provided with heat dissipation copper exposure areas 2111, so that the heat dissipation effect of the fisheye lens 21 is improved, meanwhile, the heat insulation frame 12 is sleeved on the outer side of the metal frame 11, so that the heat insulation effect is ensured while the heat dissipation is ensured, and the influence of overhigh touch temperature on the user experience is avoided; a multilayer waterproof design scheme is designed in the whole panoramic lens, so that a better waterproof effect is achieved.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
