Camera module

A camera module, comprising:

• a lens barrel, having a first portion and a second portion connected to the first portion, wherein the first portion of the lens barrel has a first through hole through the first portion;
• a front housing, accommodating the second portion of the lens barrel, wherein the first portion of the lens barrel is disposed outside the front housing and has a rear surface abutting against a front surface of the front housing such that the first through hole directly communicates with an internal space defined between the second portion of the lens barrel and the front housing;
• a circuit board, adjacent to the front housing and having a control element;
• a lens module, disposed in the lens barrel and having a front lens;
• and
• a heating module, disposed in the lens barrel, wherein the heating module comprises:
• an electrical connector, disposed in the first portion of the lens barrel and extending through the first through hole of the first portion of the lens barrel and the internal space defined between the second portion of the lens barrel and the front housing, such that the electrical connector is not exposed to an outside of the first portion of the lens barrel and is electrically connected to the control element of the circuit board;
• a heating element, in contact with the front lens of the lens module and electrically connected to the control element of the circuit board through the electrical connector;
• and
• a temperature sensor, close to the front lens of the lens module and electrically connected to the control element of the circuit board through the electrical connector, wherein the temperature sensor is configured to measure a temperature close to the front lens, and the control element turns on the heating element when the temperature is lower than a set temperature.
