DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] The directional nouns involved in the embodiments of this application, such as "upper", "lower", "side", etc., are generally expressed in the form of Figure 1 The relative relationships shown in the figure are used as a reference, and these directional terms are used only to more clearly describe the relationship between structures, not to describe absolute directions. When the product is placed in different postures, the direction may change, for example, "up" and "down" may be interchangeable.

[0038] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0039] In order to make the technical solutions and advantages of the present application clearer, the implementation methods of the present application will be described in further detail below with reference to the accompanying drawings.

[0040] The first aspect of the present application provides a camera module, such as Figure 1 、 Figure 2 and Figure 6 As shown, the camera module includes a light-transmitting part 1, a lens 2 and a heating part 3.

[0041] The light-transmitting portion 1 is located on the light-incoming side of the lens 2 .

[0042] The heat generating portion 3 is located between the lens 2 and the light transmitting portion 1 .

[0043] The orthographic projection of the heat generating portion 3 on the light transmitting portion 1 is separated from the orthographic projection of the lens 2 on the light transmitting portion 1 .

[0044] It can be understood that the lens 2 can focus the light on the light-entering side. The light-transmitting portion 1 is located on the light-entering side of the lens 2, which can not only allow light to pass through, but also protect the lens 2 from contacting and being damaged by other objects on the light-entering side. The heating portion 3 is located between the lens 2 and the light-transmitting portion 1, and can accelerate the evaporation of water droplets on the lens 2 and the light-transmitting portion 1 by generating heat, thereby preventing the light from being distorted by the water droplets, thereby maintaining the imaging quality of the camera module of the present application. At the same time, the positive projection of the heating portion 3 on the light-transmitting portion 1 is separated from the positive projection of the lens 2 on the light-transmitting portion 1, which can reduce the interference of the heating portion 3 on the lens 2, so as to facilitate the lens 2 to focus the light.

[0045] In the embodiment of the present application, the light-transmitting portion 1 is used to protect the lens 2 on the one hand and to allow light to pass through on the other hand. Therefore, it can be made of materials such as glass or transparent plastic to reduce the impact on the passing light.

[0046] In the embodiment of the present application, the lens 2 may be a convex lens, and the light passing through the lens 2 converges at the focal position of the lens 2, which is conducive to the generation of the image.

[0047] In the embodiment of the present application, the field of view of the lens 2 can be regarded as a platform, with the smaller bottom surface of the platform facing the lens 2. The orthographic projection of the heating portion 3 on the light-transmitting portion 1 is separated from the orthographic projection of the lens 2 on the light-transmitting portion 1, which can reduce the interference between the heating portion 3 and the field of view of the lens 2.

[0048] In the embodiment of the present application, the heating part 3 can generate heat and conduct it to the lens 2 and the light-transmitting part 1 through the air or other filling gas between the heating part 3 and the lens 2, and between the heating part 3 and the light-transmitting part 1, thereby increasing the evaporation rate of water droplets on the lens 2 and the light-transmitting part 1, so as to reduce the distortion caused by these water droplets when passing through the light-transmitting part 1 and the lens 2, which is conducive to the light passing through the lens 2 converging at the focal position of the lens 2.

[0049] In the embodiment of the present application, the number of the heat generating portion 3 can be one, two, three, four, or any other number. When the number is two or more, they can be arranged in a plane perpendicular to the arrangement direction of the lens 2 and the light-transmitting portion 1 so as to conduct heat to the lens 2 and the light-transmitting portion 1 at the same time.

[0050] In the embodiment of the present application, the heating portion 3 can generate heat by utilizing energy such as electricity. The heating portion 3 can be made of a metal that can generate heat when energized, such as copper or tungsten, or an alloy such as a nickel alloy or a chromium alloy.

[0051] In some of the embodiments of this application, Figure 1 As shown, the orthographic projection of the heating portion 3 on the light-transmitting portion 1 is annular and surrounds the orthographic projection of the lens 2 on the heating portion 3 .

[0052] It is understandable that the heat generated by the annular heating portion 3 can be distributed around the lens 2 and at a position on the transparent portion 1 corresponding to the field of view of the lens 2, thereby ensuring uniform heating of the lens 2 and the transparent portion 1.

[0053] In the embodiment of the present application, the orthographic projection of the heating portion 3 on the light-transmitting portion 1 is annular, and the orthographic projection of the lens 2 on the light-transmitting portion 1 is circular. The inner diameter of the orthographic projection of the annular shape is larger than the diameter of the orthographic projection of the circle. The orthographic projection of the annular shape is concentric with the orthographic projection of the circle.

[0054] In some of the embodiments of this application, Figure 3 and Figure 4 As shown, the camera module includes a bracket 4 , which has a through hole 401 . The through hole 401 passes through the bracket 4 along the arrangement direction of the lens 2 and the light-transmitting portion 1 , and the lens 2 extends into the through hole 401 .

[0055] It is understandable that the bracket 4 can support the lens 2 , the light-transmitting portion 1 and the heating portion 3 , which is beneficial for the three to maintain a relatively stable positional relationship, thereby maintaining the working performance of the heating portion 3 .

[0056] In the embodiment of the present application, the lens 2 and the side wall of the through hole 401 can be connected by bonding, clamping, etc.

[0057] In some of the embodiments of this application, Figure 1 and Figure 2 As shown, the heating portion 3 is mounted on the bracket 4 and is located on the end surface of the through hole 401 facing the light-transmitting portion 1 .

[0058] It is understood that the heating element 3 is mounted on the bracket 4, which helps to improve its stability by forming a stable connection with the bracket 4, and reduces the displacement of the heating element 3 relative to the lens 2 due to collision. The heating element 3 is located on the end surface of the through hole 401 facing the light-transmitting portion 1, which helps to transfer heat to both the light-transmitting portion 1 and the lens 2, thereby evaporating water droplets on both.

[0059] In some of the embodiments of this application, Figure 2 As shown, the bracket 4 has a first groove 402 . The first groove 402 is located at one end of the through hole 401 facing the light-transmitting portion 1 and surrounds the through hole 401 . The heating portion 3 is located in the first groove 402 .

[0060] It is understood that the heating element 3 is located within the first groove 402 and is limited by the first groove 402, making movement along the width of the first groove 402 somewhat difficult, thereby reducing interference with the lens 2 caused by displacement. The first groove 402 surrounds the through hole 401, which facilitates heat transfer from the heating element 3 to the circumference of the lens 2 and the corresponding position of the light-transmitting portion 1, thereby improving the uniformity of the evaporation rate of water droplets located therein.

[0061] In the embodiment of the present application, the first groove 402 is annular.

[0062] In the embodiment of the present application, the heating portion 3 and the wall surface of the first groove 402 can be connected by bonding or other means, so that the heating portion 3 can remain in the first groove 402.

[0063] In some of the embodiments of this application, Figure 1 and Figure 3 As shown, the camera module includes a power supply 5 , which is located on a side of the bracket 4 away from the light-transmitting portion 1 , and is electrically connected to the heating portion 3 .

[0064] It is understood that the power supply 5 can form a loop with the heating portion 3, which is conducive to the heat generation of the heating portion 3. The power supply 5 is located on the side of the bracket 4 away from the light-transmitting portion 1 to avoid interference with the field of view of the lens 2 caused by the power supply 5.

[0065] In the embodiment of the present application, the power supply 5 and the heating portion 3 may be electrically connected via a lead wire.

[0066] In some of the embodiments of this application, Figure 2 As shown, the bracket 4 has a second groove 403 , which is communicated with the first groove 402 and extends along the edge of the bracket 4 to a side of the bracket 4 opposite to the power supply 5 .

[0067] It is understood that the second groove 403 can be used to arrange the leads between the power supply 5 and the heating element 3. The second groove 403 extends along the edge of the bracket 4 to the side of the bracket 4 opposite the power supply 5, which helps to prevent the leads from protruding from the bracket 4 and being damaged by scratches from other components during assembly.

[0068] In some of the embodiments of this application, Figure 2 and Figure 5 As shown, the bracket 4 has two second grooves 403 , and the heating portion 3 has two contacts 31 . The two contacts 31 extend from the first groove 402 into the corresponding second grooves 403 .

[0069] It is understood that two leads are generally required to form a circuit between the power supply 5 and the heating portion 3. The two second grooves 403 can correspond to the number of leads. At the same time, the two contacts 31 of the heating portion 3 also facilitate the electrical connection between the leads and the heating portion 3.

[0070] In the embodiment of the present application, the lead wire can be electrically connected to the contact 31 by welding, clamping, etc.

[0071] In some of the embodiments of this application, Figure 1 As shown, the camera module includes a photoelectric sensor, which is located on the light-emitting side of the lens 2 , and the orthographic projection of the lens 2 on the light-transmitting portion 1 is located within the orthographic projection of the photoelectric sensor on the lens 2 .

[0072] It will be appreciated that the photoelectric sensor receives light focused at a focal point by lens 2 and generates a corresponding electrical signal, thereby forming an image. The orthographic projection of lens 2 on light-transmitting portion 1 is located within the orthographic projection of the photoelectric sensor on lens 2, facilitating the photoelectric sensor's coverage of light within the field of view of lens 2.

[0073] A second aspect of the present application provides an electronic device, which includes the camera module described in the above embodiment.

[0074] It can be understood that due to the adoption of the camera module of the above embodiment, the electronic device of the present application has the same technical effect as the above camera module, which will not be repeated here.

[0075] In the embodiments of the present application, the electronic device may be a smart phone, a smart watch, a tablet computer, or the like.

[0076] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless expressly limited otherwise.
