A TOF camera module and an electronic product

Abstract

The invention provides a TOF camera module and an electronic product. The TOF camera module comprises s a circuit board, a supporting seat, a lens unit and a TOF emission unit; the circuit board comprises a main body part, the supporting seat comprises a first supporting part and a second supporting part, the second supporting part is connected to one side of the first supporting part, the secondsupporting part is a metal frame, the first supporting part is a plastic frame, and the supporting seat is installed on the main body part of the circuit board; The lens unit is installed on the firstsupporting part, and the TOF transmitting unit is installed on the second supporting part. According to the TOF camera module and the electronic product provided by the invention, the second supporting part provided with the TOF transmitting unit is designed into the metal frame, so that heat generated by the TOF transmitting unit can be well transferred out, and the TOF camera module has good heat dissipation performance. Moreover, the metal frame has high strength, the second supporting part can be designed to be light and thin, and heat dissipation is better facilitated.

Description

technical field [0001] The invention relates to the technical field of TOF, in particular to a TOF camera module and electronic products. Background technique [0002] TOF (Time of Flight, time of flight) technology, by continuously sending light pulses to the target, reflecting after encountering the target object, and then using the sensor to receive the light returned from the object, and by calculating the time difference or phase difference between the light emission and emission, to calculate The distance of the object to be photographed is used to generate depth information, and further combined with traditional contact photography, so that the three-dimensional outline of the object is presented in the form of images with different colors representing different distances. [0003] The TOF camera module usually includes two parts, a TOF transmitter unit and a camera unit, and both the TOF transmitter unit and the camera unit are set on a plastic support base and conne...

AI Technical Summary

Problems solved by technology

However, the thermal conductivity of the plastic material is poor, which is not conducive to the heat dissipation of the TOF camera module, and because the strength of the plastic material is low, in order to improve its strength, the supporting base has a larger wall thickness, which further aggravates the problem of poor heat dissipation. question

In addition, ordinary circuit boards have poor thermal conductivity, which is also not conducive to the heat dissipation of TOF camera modules.
