The fourth waterproof sealing ring 2215 is disposed on the second installation surface 2213 of the upper case 221 , and is located on the upper case 221 and the outer cover 222 . In this embodiment, the fourth waterproof sealing ring 2215 is a waterproof double-sided adhesive disposed between the upper case 221 and the outer cover 222. On the other hand, the waterproof effect between the upper case 221 and the outer cover 222 can also be realized at the same time, preventing external water vapor and dust from entering the interior of the upper case 221 from the connection between the upper case 221 and the outer cover 222, resulting in the fisheye lens 21 erosion.

In the modular panoramic lens 100 provided by the present invention, four waterproof sealing designs are provided in sequence from the outside to the inside, which can meet the waterproof requirements of the entire panoramic lens 100 . Wherein, in the front case assembly 22 of the panoramic lens 100, a fourth waterproof sealing ring 2215 is arranged between the outer cover 222 and the upper case 221, and a second waterproof sealing ring 118 is arranged between the upper case 221 and the metal frame 11. . Both the fourth waterproof sealing ring 2215 and the second waterproof sealing ring 118 are made of waterproof double-sided adhesive tape, which prevents water vapor from entering the gap, and can simultaneously connect the two components. Meanwhile, when the upper case 221 is fixedly connected with the metal frame 11 , a first waterproof sealing ring 2216 is provided inside the second mounting hole 2213C, and a third waterproof sealing ring 2214 is provided between the upper case 221 and the fisheye lens 21 . The third waterproof sealing ring 2214 and the first waterproof sealing ring 2216 are both made of silicone elastic soft rubber. Through the locking of the connector and the fixing of the fisheye lens 21, the sealing ring is compressed, thereby achieving waterproofing of the installation. Sealing effect.

The two lens modules 20 in a modular panoramic lens 100 provided by the present invention are arranged symmetrically along the center, compactly installed and arranged, fully utilizing the internal space, and the main heat dissipation parts of the two lens modules 20 are vertically arranged. The circuit board 211 is distributed on both sides of the middle frame assembly 10, and the heat dissipation copper area 2111 is set on the vertical circuit board 211 to improve the heat dissipation effect of the fisheye lens 21, and at the same time, a heat insulation frame is set on the outside of the metal frame 11 12. Ensure heat dissipation while taking into account the heat insulation effect, so as to avoid the influence of user experience due to high touch temperature; design a multi-layer waterproof design scheme in the entire panoramic lens to achieve better waterproof effect.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention. Inside.
