The invention relates to a fixing base, a laser projection module and electronic equipment. The laser projection module comprises a fixing base, a light-emitting chip and an optical element. The fixing base is provided with a first surface and a second surface which are arranged oppositely in the height direction. The second surface is a light emitting surface, the fixing base is provided with a first containing cavity, a second containing cavity and a third containing cavity which are sequentially distributed in the direction from the first surface to the second surface and communicate with each other. The first inner wall of the fixing base is connected with the second inner wall of the fixing base through a first fixing face, the second inner wall is connected with the third inner wallof the fixing base through a second fixing face, and the fixing base is provided with a conduction line. The light-emitting chip is arranged on the first fixing surface of the fixing seat and is electrically connected with one end of the conduction line. The optical element is arranged on the second fixing face of the fixing base, and laser emitted by the light-emitting chip is projected to the outside of the fixing base through the third containing cavity after passing through the optical element. The safety of the laser projection module is improved.
Description
technical field [0001] The invention relates to the field of imaging technology, in particular to a fixing seat, a laser projection module and electronic equipment. Background technique [0002] The depth acquisition device used in the current 3D imaging recognition technology uses the light-emitting chip of the laser projection module to emit a laser beam with a small angle, and diffuses the laser beam into a uniform light surface or spot with a large angle through optical elements. The energy density is reduced and will not cause harm to the human body. [0003] The optical components in the laser projection module are generally composed of glass and polymer materials, which are thin and fragile. Once the optical components are not firmly bonded, fall off or break, the laser light emitted by the light-emitting chip will directly irradiate the body or eyes of the human body, causing serious safety problems.
