The invention discloses a camera lens and a preparation method thereof, a camera assembly and electronic equipment. Specifically, the invention provides a camera lens, which comprises: a substrate, wherein the substrate is provided with a window area and a texture area arranged around the window area; an appearance membrane which is attached to one side of the base plate and comprises; a substrateprovided with a first hollowed-out area, wherein the orthographic projection of the first hollowed-out area on the base plate covers the window area; a texture layer, wherein the texture layer is arranged on one side of the substrate, and the orthographic projection of the texture layer on the substrate at least covers the texture area; and a coating layer, wherein the coating layer is arranged on one side, far away from the substrate, of the texture layer. Therefore, the bonding strength between the appearance diaphragm and the substrate is relatively high, the texture effect of the camera lens is flashing, the texture layer is not easy to fall off, the appearance effect is good, the product yield is relatively high, and the production cost is relatively low.
