Abstract: This application discloses a camera module and an electronic device. The camera module includes a photosensitive chip, a first lens barrel, a first lens, a rotating assembly, an elastic member, and a drive mechanism. The first lens barrel is provided with the first lens that is disposed opposite the photosensitive chip. The rotating assembly fits around the first lens barrel, and is connected to the rotating assembly via a first fitting convex portion and a first spiral guide slot. The rotating assembly includes a body member and a transmission member that are disposed separately. A first end of the elastic member is connected to the body member, and a second end of the elastic member is connected to the transmission member. The drive mechanism is connected to the transmission member, and the drive mechanism drives, via the transmission member, the elastic member, and the body member in turn.

Abstract: Provided are a method of preparing a malononitrile oxime ether compound and an intermediate compound. The malononitrile oxime ether compound has a structure as shown in formula (VII), wherein W is selected from aryl or heteroaryl. The preparation method comprises: reacting a first raw material with a second raw material in the presence of a first solvent and a catalyst to obtain the intermediate compound, wherein the first raw material has a structure as shown in formula (IV), and the second raw material has a structure as shown in formula (V); and subjecting the intermediate compound, and a dehydrant to a dehydration reaction in the present of a second solvent to obtain the malononitrile oxime ether compound. Furthermore, the malononitrile oxime ether compound is obtained through one-step dehydration reaction. using the preparation method, is advantageous for improving the yield of malononitrile oxime ethers and reducing the cost.
