An internal view lens structure with an automatic horizontal function, comprising a shell member, a bearing, a main eccentric member, an electronic slip ring, a camera lens module, a secondary eccentric member and a light source module, wherein the bearing assembly is disposed in the shell member, The main eccentric member is an eccentric weight structure, the sleeve is assembled and rotatable relative to the bearing, and the electronic slip ring and the camera lens module are disposed on the main eccentric member, and the auxiliary eccentric member is also eccentrically matched. The weight structure is coupled to the main eccentric member and rotates along the main eccentric member, the light source module is disposed on the auxiliary eccentric member, and the main eccentric member and the auxiliary eccentric member are eccentrically weighted to enable the camera lens The shooting direction of the module and the illumination direction of the light source module are automatically horizontal.一種具自動水平功能之內視鏡頭部結構，包含殼件、軸承、主偏心件、電子滑環、攝像鏡頭模組、副偏心件以及光源模組，該軸承組設於該殼件內，該主偏心件為偏心配重結構，穿套組設該軸承並可相對於該軸承旋轉，該電子滑環與該攝像鏡頭模組設置定位在該主偏心件上，該副偏心件亦為偏心配重結構，組接於該主偏心件並跟著該主偏心件旋轉，該光源模組設置定位在該副偏心件上，該主偏心件與該副偏心件透過偏心配重原理可使該攝像鏡頭模組的拍攝方向、光源模組的照射方向自動呈水平狀態。
