However, depending on the location, the amount of current required to be supplied to the motor coil is different, making the motor coil the key to the heat source
Generally speaking, the motor coils are located on the left and right sides of the lower half of the lens, so when the motor is powered on, the lens in the upper half of the lens is heated differently from the lens in the lower half of the lens, resulting in different shrinkage of the lens in the X-Y direction, and then Affects the imaging resolution of the lens
In addition, most of the moving parts inside the lens and motor are made of plastic materials. The thermal conductivity of plastic materials is about 0.2W / (m.K) to 0.3W / (m.K), and the heat dissipation effect is not good.

The invention provides a lens module, which includes a first bearing seat, a second bearing seat, a third bearing seat, a plurality of lenses and an actuator. The second bearing seat is disposed in the first accommodating space of the first bearing seat. The third bearing seat is disposed in the second accommodating space of the second bearing seat. The thermal conductivity of the second carrier is different from the thermal conductivity of the third carrier. The thermal conductivity of one of the second carrier and the third carrier is between 0.9W / (m.K) and 20W / (m.K). The lens is arranged in the third accommodating space of the third bearing seat. One of the coil assembly and the magnet assembly of the actuator is disposed on the first bearing seat and located in the first accommodating space. The other of the coil assembly and the magnet assembly of the actuator is disposed on the second bearing base, and the coil assembly and the magnet assembly are disposed corresponding to each other. The lens module of the present invention has better heat dissipation effect and imaging resolution.
Description
technical field [0001] The present invention relates to an optical module, in particular to a lens module. Background technique [0002] In the current lens module, when the lens module is focusing, the motor is powered on, so that the motor-carrying lens component is moved to the position with the best resolution. However, according to different positions, the amount of current required to be supplied to the motor coil is different, which makes the motor coil the key to the heat source. Generally speaking, the motor coils are located on the left and right sides of the lower half of the lens, so when the motor is powered on, the heating of the lens on the upper half of the lens is different from that of the lens on the lower half of the lens, resulting in different shrinkage of the lens in the X-Y direction, and then Affects the imaging resolution of the lens. In addition, most of the moving parts inside the lens and the motor are made of plastic materials. The thermal con...
