[0029] See also Figure 1 , Figure 1 The present application provides a self-heating camera module 100, which includes a lens 1 and a heating element 2. The heating element 2 generates heat when powered on, which is used to heat the lens 12.

[0030] The lens 1 comprises a lens barrel 11, a lens 12 disposed in the lens barrel 11 and exposed from one end of the lens barrel 11, and a first support 13. The first support 13 is protruded from the outer wall of the lens barrel 11 along a direction perpendicular to the axis of the lens barrel 11.

[0031] Please refer to Figure 2 , Figure 2 1 is a schematic diagram of the structure of the heating body provided in this embodiment. The heating body 2 is sleeved on the outer wall of the lens barrel 11 from one end of the lens 12 exposed from the lens barrel 11, and is located between the lens 12 and the first support 13. Specifically, the heating body 2 is an annular body, and is provided with a mounting hole 24 that penetrates the heating body 2 along the axial direction of the heating body 2. The heating body 2 includes an inner wall 22 and a bottom wall 23 that surround the mounting hole 24. When the heating body 2 is sleeved on the lens barrel 4, the inner wall 22 fits the outer wall of the lens barrel 11, and the bottom wall 23 fits the first support 13 and is supported by the first support 13. In this embodiment, the heating body 2 has a self-limiting temperature effect, that is, the heating body 2 is limited to heating the lens 12 within a certain temperature range. When the temperature of the lens is lower than the minimum operating temperature, the heating body 2 is energized, and the temperature of the heating body 2 rises. When the temperature of the heating body 2 rises to a preset temperature, the temperature of the heating body 2 no longer rises, and the operating temperature of the heating body 2 is limited to the preset temperature, which effectively avoids damage to the lens 12 caused by the excessive temperature of the heating body 2. In this embodiment, the size of the heating body 2 is 1-5 mm and the inner wall 22 and the bottom wall 23 are in contact with the lens 1 to heat the lens 12. The heating area is large and the heating effect on the lens 12 is good. It can be understood that since the heating body 2 can have a temperature limiting effect, a large voltage can be provided to quickly allow the heating body 2 to reach a preset temperature without causing the temperature of the heating body 2 to be too high.

[0032] The first support body 13 is also an annular body, and the inner diameter of the heating body 2 is smaller than the outer diameter of the first support body 13, and the outer diameter of the heating body 2 is larger than the outer diameter of the first support body 13. In this embodiment, the heating body 2 is inserted from the end of the lens 1 close to the lens 12 along the direction of the axis of the lens barrel 11 and is clamped on the lens 1. It can be understood that the outer wall of the lens barrel 11 and the first support body 13 both play a limiting role on the heating body 2. In this embodiment, the lens 1 also includes a second support body 14, which is convexly arranged on the outer wall of the lens barrel 11 along the direction perpendicular to the axis of the lens barrel 11, and the end face of the second support body 14 facing away from the lens 1 is fixedly connected to the lens 1 and the face shell 5 by AA glue.

[0033] The heating body 2 includes a ceramic shell 25, and a heating slurry is provided inside the ceramic shell 25. Since the heating slurry is arranged inside the ceramic shell 25, the heating slurry is not affected by external forces, and there is no risk of breakage. In this embodiment, the heating body 2 is sintered in a high temperature environment of +1600°C using a customized mold, and has excellent high temperature resistance. It can be understood that the heating body 2 is not necessarily sintered into a ring shape. Without considering the size of the product, a customized mold can be used to sinter any solid object designed to be provided with a mounting hole to adapt to the shape of different lenses, for example, a block with a mounting hole, or other irregular shapes, etc.

[0034] The camera module 100 also includes a heating circuit board 3, which is arranged on the side of the lens 1 away from the heating body 2. The heating body 2 is provided with a conductor 21, one end of the conductor 21 is electrically connected to the heating body 2, and the other end is electrically connected to the heating circuit board 3. The heating circuit board 3 is used to provide or stop providing a heating voltage to the heating body 2. Among them, the heating circuit board 3 is also provided with a first notch 31 for the conductor 21 to pass through and a socket 32 ​​for the conductor 21 to be electrically connected. In this embodiment, the camera module 100 also includes a sensor circuit board (not shown), and the sensor circuit board is also provided with a second notch (not shown) for the conductor 21 to pass through. The sensor circuit board is placed parallel to the heating circuit board 3. In this embodiment, the conductor 21 first passes through the second notch, then passes through the first notch 31, and finally is plugged into the socket 32 ​​of the heating circuit board 3. Among them, the conductor 21 is designed to be L-shaped, which is convenient for the conductor 21 to be plugged into the socket 32.

The camera module 100 also includes a bottom shell 6, a front shell 5 and a mask 4. The bottom shell 6 and the mask 4 are respectively assembled on the opposite sides of the front shell 5 and form a receiving space with the front shell 5 for receiving the lens 1, the heating body 2, and the heating circuit board 3. It can be understood that the receiving space also receives other components of the camera module 100, for example, the second sealing member 8, the first sealing ring 9, the second sealing ring 10, etc.

The camera module 100 also includes a first seal 7 and a second seal 8, the first seal 7 is arranged around the lens 12, the second seal 8 is arranged around the lens barrel 11, and is located between the heating body 2 and the first seal 7, the mask 4 is provided with an opening 41, a hole wall 42 surrounding the opening 41, and an annular convex edge 43 extending from the hole wall 42, the lens 1 is exposed from the opening 41 and surrounded by the convex edge 43, when the mask 4 and the face shell 5 are assembled together, the first seal 7 is located at the convex edge 43 and the first seal 7 is embedded between the hole wall 42 and the lens 1, and the second seal 8 is squeezed and arranged between the convex edge 43 and the heating body 2. In this embodiment, the first seal 7 is a sealant, and the second seal 8 is a sealing foam, which has the characteristics of anti-vibration and high temperature resistance. During the operation of the camera, the camera may face various vibrations, and the sealing foam can effectively reduce the influence of vibration on heat conduction and ensure the stability of the heat dissipation effect. In addition, the sealing foam can withstand high temperature environments and will not melt due to high temperatures, ensuring that the camera can work normally in high temperature environments.

[0037] Please refer to Figure 5 , Figure 5 1 is a schematic diagram of the structure of the sealing ring provided in this embodiment. The camera module 100 also includes a first sealing ring 9 and a second sealing ring 10.
