The heating device includes a heating element 11 and a conductive element 12 that is electrically connected to the heating element 11 and supplies power to it. It also includes a power supply area 2 for supplying power to the heating device. One end of the conductive element 12 away from the heating element 11 is provided with a bonding area 13. The bonding area 13 can be fixed on the power supply area 2 through a bonding process and form an electrical connection with it. In this embodiment of the present application, the connection of the conductive element on the heating device is connected to the power supply area through a bonding process. This implementation manner has a simple structure, and the connection of the conductive element occupies a small space, making the lens and the module end wiring more flexible.

[0033] Furthermore, asFigure 5 , 6 As shown in FIGS. 12 and 13, a plurality of conductive PIN pins 10 are provided on the bonding area 13, and power supply PIN pins 20 corresponding to the conductive PIN pins 10 are provided on the power supply area 2. When connecting, the PIN pins on the bonding area 13 need to be electrically connected to the corresponding PIN pins on the power supply area 2 for power supply, and then the heating element can operate normally through the conductive element. Through this connection method, the automatic assembly between the lens with a wire and the module can be realized. The bonding method does not require a terminal interface, which is beneficial to improving production.

[0034] Furthermore, the conductive element 12 is an FPC flexible circuit board. One end of the conductive element 12 far from the heating element 11 is bent horizontally to form a connecting portion 14. The bonding area 13 is arranged on the upper side of the connecting portion 14. When connecting, the PIN pins on the FPC need to correspond to the PIN pins on the power supply area 2. This design is convenient for connection, and the space occupied by the connection of the conductive element is small.

[0035] As a preferred embodiment of the present application rather than a limitation, as Figures 1 - 6 shown in Embodiment 1, the conductive element 12 extends to the rear side of the lens barrel 3. A first substrate 6 is attached to the rear side of the lens barrel 3. The power supply area 2 is arranged on the first substrate 6. The conductive element leads out from the inside of the lens barrel, and the interface is connected to the bottom substrate of the lens barrel through a bonding process. When connecting, the PIN pins on the FPC need to correspond to the PIN pins on the substrate. During operation, the module end is powered by contacting the substrate through the PCB board contacts, and then the heating element can operate normally through the conductive element. This embodiment has a simple structure, and the space occupied by the connection of the conductive element is small, making the wiring between the lens and the module end more flexible. It can be widely used for the circuit connection between various components, and through this connection method, the automatic assembly between the lens with a wire and the module can be realized, which is beneficial to improving production efficiency and reducing costs.

[0036] As a preferred embodiment of the present application rather than a limitation, as Figures 7 - 8 shown in Embodiment 2, the conductive element 12 extends to the rear side of the lens barrel 3. The power supply area 2 is etched on the lens barrel 3, and the conductive element is directly connected to the lens barrel. The difference between Embodiment 2 and Embodiment 1 is that the substrate is cancelled, the PIN pins are located at the bottom of the lens barrel, and the FPC interface circuit is etched on the lens barrel. This design has a simple structure, and the space occupied by the connection of the conductive element is even smaller.

[0037] Further, in Embodiments 1 and 2, the heating element 11 abuts against the first lens 4 to directly heat the first lens 4. A wire passing channel 30 is provided on the side wall of the lens barrel 3. The conductive element 12 extends through the wire passing channel 30 to the rear side of the lens barrel 3. The conductive element exits from the inside of the lens barrel, and the interface is correspondingly connected to the power supply area at the bottom of the lens barrel through a bonding process. When connecting, the PIN pins on the FPC need to correspond to the PIN pins on the power supply area. During operation, the module end contacts the power supply area through the PCB board contacts for power supply, and then the heating element operates normally through the conductive element. This implementation method has a simple structure, and the space occupied by the connection of the conductive element is small, making the lens and the module end flexible cable more flexible.

The difference between Embodiment 3 and Embodiment 2 is that the heat conductive element exits externally, the interface is bonded to the base, the PIN pins are located at the bottom of the base, the interface circuit is directly etched on the base, and the conductive element is directly attached to the base. This design is convenient for assembly, and the lens and the module end flexible cable are more flexible.

[0039] As a preferred implementation manner rather than a limitation of the present application, as Figures 11 - 13 shown in Embodiment 4, a base 7 is provided at the rear end of the lens barrel 3, the power supply area 2 is etched on the base 7, and the conductive element 12 extends toward the rear side of the base 7. The difference from Embodiment 1 is that the heat conductive element exits externally, and the interface is correspondingly connected to the substrate at the bottom of the base through a bonding process. When connecting, the PIN pins on the FPC need to correspond to the PIN pins on the substrate. During operation, the module end contacts the substrate through the PCB board contacts for power supply, and then the heating element operates normally through the conductive element. This implementation method has a simple structure, and the space occupied by the connection of the conductive element is small, making the lens and the module end flexible cable more flexible. It can be widely used for the circuit connection between various components, and through this connection method, the automatic assembly between the lens with a wire and the module can be realized, which is beneficial to improving production efficiency and reducing costs.

[0040] Further, in Embodiments 3 and 4, the heating element 11 is disposed on the gland 5 to indirectly heat the first lens 4 through the gland 5. The conductive element 12 passes through the gland 5 and extends rearward. The conductive element leads out from the outside of the lens barrel, and the interface is correspondingly connected to the power supply area at the bottom of the base through a bonding process. When connecting, the PIN pins on the FPC need to correspond to the PIN pins on the power supply area. During operation, the module end contacts the power supply area through the PCB board contacts to supply power, and then the heating element operates normally through the conductive element. This implementation method has a simple structure, and the space occupied by the connection of the conductive element is small, making the lens and the module end flexible.
