Abstract: A defog lens for vehicles includes a lens barrel, a lens, and a hydrophilic layer. The lens barrel has an opening toward an object side. The lens is disposed in the lens barrel and is located at the opening. The hydrophilic layer covers a surface of the lens and includes silicone compounds. Water droplets condensed on the lens could form a sheet film sticking to the surface of the lens and hard to form spherical water droplets, thereby improving the problem that the field of view of the conventional lens is blocked by spherical water droplets, effectively improving the clarity of the image captured by the defog lens, and therefore the defog lens could be applied to various environments.

Abstract: A defrosting lens includes a lens barrel having an opening toward an object side, a first lens disposed in the lens barrel and located at the opening, and a heating member. The heating member is for providing a heat source and is disposed between an inner wall of the lens barrel and the first lens. The heating member is arranged along a peripheral edge of the first lens. By raising a temperature of the first lens through the heat source supplied by the heating member, frost formed on the first lens could be removed, thereby a definition of an image captured by the defrosting lens could be effectively improved, and the defrosting lens could be applied in various environments without being limited by the change of climate temperature difference.

Abstract: A cabinet includes a number of drawers slidably attached to the receptacle which has a track, each drawer includes an actuator having two inclined surfaces and a flat surface, a number of latch members are slidably received in the track of the receptacle and each includes two end inclined surfaces for engaging with the inclined surfaces of the actuators, and a spring biasing device may bias the end protrusions of the latch members to anchor the other drawers to the receptacle, and thus to anchor and lock the other drawers to the receptacle when one of the drawers is pulled and moved out of the receptacle, and to prevent the other drawers from slipping out of the receptacle inadvertently.
