Heat generated in the working process of the functional assembly 700 is firstly conducted to the circuit board 300, then can be conducted to the copper-exposed area 311 in the circuit board 300, is conducted to the front shell 110 through the third heat-conducting piece 600 in the copper-exposed area 311, and is conducted to the outside through the front shell 110, so that heat dissipation is realized; the heat can be conducted to the first heat conducting member 400 through the circuit board 300, and the first heat conducting member 400 conducts the heat to the front shell 110 and to the outside through the front shell 110, so that the heat dissipation is realized; or may be conducted to the second heat conducting member 500 through the circuit board 300, and the second heat conducting member 500 conducts heat to the rear case 120 and then to the outside through the rear case 120, thereby realizing heat dissipation. For current heat dissipation approach, the heat radiating area of the above-mentioned module of making a video recording 10 is great, and the heat dissipation approach is more, can be fast with inside heat conduction to the external world, avoids thermal accumulation for inside temperature maintains under operating condition, can satisfy normal work demand on the one hand, improves user experience, and on the other hand can also keep the reliability of each part, improves the life of the module of making a video recording 10. Therefore, the mobile terminal with the camera module 10 has the advantages of good heat dissipation effect, good user experience and long service life.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
