Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] This utility model provides a camera module capable of heating the lens, which includes a PCB board, a housing, a heating element, a heat-conducting sheet, and a lens. The housing is fixed to the upper surface of the PCB board; the heating element is disposed on the PCB board; one end of the heat-conducting sheet is connected to the heating element, and the other end of the heat-conducting sheet is fixed to the upper surface of the housing; the lens is disposed above the housing, and the back of the protrusion of the lens abuts against the heat-conducting sheet.

[0026] Because the PCB board has a heating element connected to a heat-conducting plate, which abuts against the back of the lens protrusion, the heating element can be activated to heat the lens when the host software or manual judgment determines that defogging or water removal is required. The heat emitted by the heating element is transferred to the back of the lens protrusion through the heat-conducting plate, thereby heating the lens. Water mist and water droplets on the lens can be evaporated after heating, avoiding affecting the driver's normal use and improving the product's competitiveness.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] Example 1, please refer to Figures 1 to 5 This invention provides a camera module capable of heating the lens, comprising a PCB board 1, a housing 2, a heating element 3, a heat-conducting plate 4, and a lens 5. The housing 2 is fixed to the upper surface of the PCB board 1; the heating element 3 is disposed on the PCB board 1; one end of the heat-conducting plate 4 is connected to the heating element 3, and the other end of the heat-conducting plate 4 is fixed to the upper surface of the housing 2; the lens 5 is disposed above the housing 2, and the back of the protrusion of the lens 5 abuts against the heat-conducting plate 4. Because the heating element 3 is disposed on the PCB board 1, and the heating element 3 is connected to the heat-conducting plate 4, which abuts against the back of the protrusion of the lens 5, when the host software or manual determination indicates that defogging or dehydration is required, the heating element 3 can be activated to heat the lens. The heat emitted by the heating element 3 is transferred to the back of the protrusion of the lens 5 through the heat-conducting plate 4, thereby heating the lens 5. Water mist and droplets on the lens 5 can be evaporated after heating, avoiding interference with the driver's normal use and improving the product's competitiveness.

[0029] Furthermore, the outer shell 2 is made of aluminum alloy, and the heat-conducting sheet 4 is made of copper. Taking advantage of the fact that copper has a higher thermal conductivity than aluminum alloy, copper sheets are added during the manufacturing of the aluminum alloy outer shell 2 to achieve rapid and effective heat conduction to the lens 5.

[0030] Example 2, please refer to Figures 1 to 5 As a further optimization of Embodiment 1, in this embodiment, there are two heating elements 3, which are respectively disposed on both sides of the PCB board 1.

The outer shell 2 is provided with a groove 21 for the connecting part 41 to pass through and a stepped groove 22 for placing the heat-conducting part 42, so that the heat-conducting sheet 4 can pass through the outer shell 2 and abut against the lens 5, thereby allowing the heat emitted by the heating element 3 to be quickly transferred to the lens 5, so as to achieve rapid water removal and defogging, and improve the competitiveness of the product.

[0031] Furthermore, the heating element 3 includes a base 31 and a wave-shaped clamping part 32 disposed on the base 31. The base 31 is fixed to the PCB board 1 and electrically connected to it. The wave-shaped clamping part 32 can clamp the heat-conducting sheet 4 well and transfer heat to the heat-conducting sheet 4.

[0032] Furthermore, the lower surface of the outer shell 2 is provided with four threaded holes 23, and the PCB board 1 is provided with two fixing holes 11. The two fixing holes 11 are located at two points on the diagonal of the PCB board 1, and each fixing hole 11 is provided with a bolt 6. That is, there are two bolts 6 in this embodiment. The size and position of the two fixing holes 11 correspond to the size and position of the two threaded holes 23. The PCB board 1 is fixed to the two threaded holes 23 by the two bolts 6, thereby realizing the fixation between the outer shell 2 and the PCB board 1.
