The lens 12 is coupled to the carrier 11. The image sensor 13 is fixed to the carrier 11 and the image sensor 13 has a gap with the carrier 11. The heat conducting member 14 is fixed to the carrier 11 , and the heat conducting member 14 is in contact with the carrier 11 and the image sensor 13 , and the heat conducting member 14 extends to a sidewall of the carrier 11 . The carrier 11 is detachably connected to the outer casing 15, and the carrier 11, the lens 12, the image sensor 13, and the heat conducting member 14 are disposed in the outer casing 15. The gap between the image sensor 13 and the carrier 11 can increase the contact area of the image sensor 13 with the air to increase the natural convection heat dissipation; on the other hand, the heat conducting member 14 can be disposed between the gaps. The heat conducting member 14 can quickly introduce heat generated by the image sensor 13 into the carrier 11 and be conducted from the carrier 11 to the outer casing 15 to increase heat conduction and heat dissipation.

The carrier 11 includes a first base 111 and a second base 112. The first base 111 is detachably connected to the second base 112. Specifically, the first base 111 is provided with a threaded hole, and the second base 112 is provided with a threaded protruding column, and the threaded hole is equal to the number of the protruding column. The first base 111 is detachably mounted to the second base 112 by the threaded hole being engaged with the thread of the boss. The carrier 11 is provided with two first pedestals 111, the second pedestal 112 is disposed between the two first pedestals 111, and the second pedestal 112 and the two first bases There is a gap between the seats 111. One end of the protruding post is embedded in the threaded hole of one of the first bases 111, and the other end is embedded in the threaded hole of the other first base 111 to fix the two first bases 111. . In order to increase heat dissipation, the first pedestal 111 may be made of a material that can thermally conduct heat and has good thermal conductivity. For example, the first pedestal 111 is made of an aluminum material, wherein aluminum has a fast heat conduction and absorbs heat quickly. . In some other embodiments, the first pedestal 111 can also be made of copper or other suitable material.

It is to be understood that, in some other embodiments, the first base 111 is provided with a threaded raised post, and the second base 112 is provided with a threaded hole through which the threaded hole is The threaded engagement of the raised posts causes the first base 111 to be detachably mounted to the second base 112.

Since the heat conducting member 14 and the second pedestal 112 have a small contact area with air, natural convection heat dissipation is slow, and there is a contact gap between the second pedestal 112 and the first pedestal 111, and therefore, To dissipate heat sufficiently, a heat dissipating member (not shown) may be disposed between the second pedestal 112 and the gap of the first pedestal 111. The heat dissipating member may be made of a material with good heat dissipation effect. For example, the heat dissipating member is made of silica gel, that is, the heat dissipating member is a heat dissipating silica gel. Rapid heat conduction can be further ensured by providing the heat sink. The side wall of the second pedestal 112 is in contact with the outer casing 15 to quickly introduce heat generated by the operation of the image sensor 13 from the heat conducting member 14 to the carrier 11 and then conducted by the carrier 11 To the outer casing 15.

The lens module 100 is provided with two of the lenses 12, and the two lenses 12 are respectively disposed on opposite sides of the carrier 11.

The image sensor 13 is in direct contact with the heat conducting member 14. Since the lens module 100 is provided with two of the lenses 12, correspondingly, the image sensor 13 is two. Two of the image sensors 13 are disposed on opposite sides of the second pedestal 112. The image sensor 13 is an element for converting an optical image into an electronic signal. Since the image sensor 13 belongs to a power device, it generates a lot of heat during operation, and if it does not dissipate heat in time, it may affect the normal operation of the image sensor 13. In particular, when the distance between the two image sensors 13 is very close, the amount of heat generation is greatly increased, and since the two lenses 12 are symmetrically arranged, the image sensor 13 cannot be dissipated by the fan, but only by natural convection; However, since the internal convection area of the lens module 100 is small, the heat generated when the image sensor 13 operates is not easily diffused. Therefore, in order to quickly guide the heat dissipation, the image sensor 13 and the heat conductive member 14 are directly Contact to increase heat and heat. The image sensor 13 may be a Charge Coupled Device (CCD) or a Complementary Metal-Oxide Semiconductor (CMOS) or the like.

The heat conducting member 14 may be made of a material having good thermal conductivity. For example, the heat conducting member 14 is made of a material such as copper foil or copper, that is, the heat conducting member 14 may be a heat conductive copper foil. And the second pedestal 112 can be made of aluminum, because the aluminum heat conduction is fast, and the heat absorption is fast, and the heat conduction of the copper foil is faster than that of the aluminum, and the heat absorption is relatively slow, so the heat conducting member 14 is combined. In association with the characteristics of the second pedestal 112, the heat conducting member 14 rapidly conducts heat generated by the image sensor 13 to the second pedestal 112, and the second pedestal 112 absorbs heat rapidly, thereby increasing heat conduction. And heat dissipation. Since the lens module 100 is provided with two of the image sensors 13, correspondingly, the heat conducting members 14 are also provided with two, one of the heat conducting members 14 and one of the image sensors 13 and the second base.

The inner surface of the curved casing 152 is provided with a heat absorbing layer (not shown), and the heat absorbing layer is made of a material that can absorb heat radiation, and the heat absorbing layer may be graphene or the like. Since the internal space of the lens module 100 is small and is a closed structure, the fluidity of the internal air is poor, or even substantially no flow, and there is no convection, so that the temperature difference between the outer casing 15 and the lens 12 is relatively obvious. Therefore, the heat generated by the lens 12 can be transmitted to the outer casing 15 through the heat absorbing layer disposed on the inner surface of the curved casing 152 to achieve rapid heat conduction and heat dissipation. The effect of cooling the interior of the lens module 100 is achieved. There are two arc-shaped casings 152, and correspondingly, the heat-absorbing layers are also two.

Specifically, the first pedestal 111 and the second pedestal 112 are both provided with circular through holes, and the circular through holes have a diameter slightly larger than the diameter of the rotating shaft 211, so that the first pedestal The second base 112 and the second base 112 can be sleeved on the rotating shaft 211. Moreover, the rotating shaft 211 is rotatable relative to the first base 111 and the second base 112.
