Patent Description:
This disclosure relates to the field of photographing technologies, and in particular, to a camera assembly and an electronic device.

Nowadays, photographing performance is one of important indicators used by a consumer to select a consumer electronic device. An electronic device is equipped with a rotatable camera module to have a large angle stabilization function. However, when the camera module rotates, one end of a bottom of the camera module is suspended. Consequently, the bottom is wrapped by air, and heat dissipation of the camera module is hindered. When a temperature of an element (for example, an image sensor or a lens) in the camera module is very high, photographing performance, for example, a focusing speed, image resolution, or image noise, of the electronic device is significantly affected.

Document <CIT>relates to an optical unit with rolling correction function which performs rolling correction by fixing a circuit board on which an imaging element is mounted and a heat dissipating member to a rotation member, transmitting heat from the circuit board to the heat dissipating member, and rotating the rotation member. A rotation shaft of a rotation supporting mechanism is fixed to the rotation member via the heat dissipating member. Accordingly, it is possible to dissipate heat by transmitting heat that is generated from the imaging element, from the circuit board to the heat dissipating member, and then transmitting the heat from the heat dissipating member to the rotation shaft. The imaging element and the heat dissipating member overlap with the rotation shaft at an identical position when the imaging element and the heat dissipating member are seen from an optical axis direction. The heat dissipating member may have a heat dissipating member main body and a protrusion part that is bent at an outer circumferential edge of the heat dissipating member main body towards a counter object side.

Document <CIT> describes a flexible printed circuit board in a small space with high flexibility in an optical unit with shake correction function. In an optical unit with rolling correction function, a first flexible printed circuit board for an imaging element is drawn around an optical axis of the optical unit with rolling correction function such that the first flexible printed circuit board is wound by substantially a turn in a circumferential direction at an identical height in an optical axis direction. Furthermore, in a portion wound in the circumferential direction (i.e., a connection part), one end and the other end in the circumferential direction are at an identical height in the optical axis direction. Moreover, a second flexible printed circuit board for a rolling magnetic driving mechanism and a third flexible printed circuit board for a swing magnetic driving mechanism are described.

Document <CIT> is directed to a physical assembly including a magnet mount for physically receiving a physical module that includes a housing having a rear surface of a first shape. The magnet mount includes a first surface, a second surface and a magnetic material. The first surface is configured to attach to a mounting surface. The second surface has a second shape that is substantially complementary to the first shape, and is configured to engage the rear surface of the housing of the physical module. The magnetic material is disposed between the first and second surfaces and configured to magnetically couple to a magnetic material of the physical module. When the physical module is magnetically coupled to the magnet mount, an adjustable union between the magnet mount and the physical module is formed permitting adjustment of an angle of orientation of the physical module with respect to the magnet mount.

Document <CIT> discloses a camera module comprising a thermoelectric device disposed at the rear camera housing portion, and a heat transfer element is disposed between and in thermal conductive contact with the thermoelectric device and the imager printed circuit board. The thermoelectric device is electrically powered to draw heat from the imager printed circuit board to the rear camera housing portion.

A structure of an electronic device provided in the eleventh implementation is approximately the same as the structure of the electronic device provided in the first implementation. <FIG> is a schematic diagram of a partial structure of an electronic device according to an eleventh implementation of this disclosure. A difference is that a first fastened module and a second fastened module are omitted from a camera assembly <NUM>.

The thermoelectric cooler is made based on a Peltier effect of a semiconductor material. The Peltier effect is a phenomenon in which one end absorbs heat while the other end discharges heat when a direct current flows through a galvanic couple including two semiconductor materials. Heavily doped N-type bismuth telluride and P-type bismuth telluride are mainly used as semiconductor materials the TEC, and bismuth telluride elements are electrically connected in series and emit heat in parallel. The TEC includes some pairs (groups) of P-type bismuth telluride and N-type bismuth telluride, the pairs are connected together by using an electrode, and are sandwiched between two ceramic electrodes. When a current flows through the TEC, heat generated by the current is transferred from one side of the TEC to the other side, and a "hot" side and a "cold" side are generated on the TEC. This is a heating and cooling principle of the TEC.
