[0002] In existing electronic devices, a camera is generally indispensable. The camera can generally be composed of a lens and an image sensor. Specifically, when it is necessary to take a picture of the outside world, the external light enters the camera, and the lens can refract and converge the light, so that the light reflected or emitted by the object can be accurately focused on the image sensor to form a clear image. The image sensor can convert the light signal focused by the lens into an electrical signal.
[0003] With the increasing requirement for image quality, the amount of data processed by the image sensor increases, which causes the power consumption of the image sensor and other components to increase, and in turn causes the heat generation to increase. However, the existing camera mainly performs heat dissipation by providing heat dissipation holes on the shell and optimizing the circuit layout, etc. These methods may not be able to effectively dissipate the heat. Further, when the electronic device is an augmented reality (AR) glasses, due to the limited installation space on the AR glasses, a fan or other means cannot be used for heat dissipation. As the heat cannot be effectively dissipated, the temperature of the camera increases, which may affect the performance and stability of the camera, and even may cause the camera to malfunction.

[0036] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0037] Figure 1 Exemplary structural diagrams of camera structures for electronic devices according to some embodiments of this application are shown. For example... Figure 1 As shown, the camera structure includes a lens barrel portion 10 and a base portion 20 connected to the lens barrel portion 10. The camera structure also includes a first heat dissipation assembly 30 and a second heat dissipation assembly 40. The first heat dissipation assembly 30 includes a first heat dissipation lens barrel assembly 31 and a second heat dissipation lens barrel assembly 32 connected to the first heat dissipation lens barrel assembly 31. The first heat dissipation lens barrel assembly 31 covers the side of the lens barrel portion 10, and the second heat dissipation lens barrel assembly 32 covers the side of the base portion 20. The second heat dissipation assembly 40 is disposed on a first bottom side 21 of the base portion 20, wherein the first bottom side 21 is the side facing away from the lens barrel portion 10. The second heat dissipation lens barrel assembly and the first heat dissipation lens barrel assembly form a stepped portion, and a second side of the base portion abuts against the stepped portion, wherein the second side of the base portion faces the lens barrel portion.
[0038] In some embodiments, the first heat dissipation component 30 is composed of a first heat conductive material, and the second heat dissipation component 40 is composed of a second heat conductive material.
[0039] In some embodiments, the aforementioned electronic device can include a mobile phone, a tablet computer, a vehicle-mounted device, a virtual reality (VR) glasses, an AR glasses, and the like. Some embodiments of the present disclosure take the mobile phone as an example for illustration.
[0040] In some embodiments, the camera of the AR glasses can capture the surrounding environment, thereby providing the AR glasses with visual information about the real world. With these information, the AR glasses can recognize objects, planes, landmarks and other elements in the scene, thereby understanding the environment in which the user is located, and providing a basis for subsequent virtual content superimposition and interaction. Further, the camera captures images of the real scene, which are fused with virtual content, so that virtual elements can be seamlessly combined with the real environment, presenting a realistic augmented reality effect. At the same time, the camera can also track the user's actions and changes in the surrounding environment, and adjust the display of virtual content to achieve a natural interactive experience. Furthermore, the camera also has the functions of taking pictures and recording videos, which can facilitate the user to record the wonderful moments in the real scene and the AR experience, and save images and videos with virtual elements superimposed.
[0041] In some embodiments, the lens barrel part 10 can be provided in the shape of a cylinder, a cube or the like. The inside of the lens barrel part 10 can be provided with optical elements, wherein the optical elements can include multiple layers of lenses (such as convex lenses, concave lenses, etc.). Specifically, when the external light enters the inside of the camera, the lenses can refract and converge the light, so that the light reflected or emitted by the object can be accurately focused on the image sensor, forming a clear image.
[0042] It can be understood that, by different combinations of lenses, different focal lengths and focusing ranges can be achieved to adapt to shooting objects at different distances, ensuring that the AR glasses can shoot clear pictures in various scenes. Further, these lenses can assist in correcting the propagation direction of light, ensuring that light entering the camera from different angles can reach the image sensor along the correct path, reducing light scattering and distortion, thereby improving the clarity and quality of the image. Furthermore, by providing special coatings or materials on some lenses, specific wavelengths of light such as ultraviolet light or infrared light can also be filtered out. In this way, the contrast and color accuracy of the image can be enhanced, and unnecessary light interference on the image can be reduced, making the captured image closer to the real scene seen by the human eye, providing higher quality raw image data for image recognition and processing of the AR glasses.
[0043] In some embodiments, the base portion 20 can also be provided in the shape of a cylinder or a cube, etc. It should be understood that the shell of the base portion 20 and the shell of the lens barrel portion 10 can be connected together by one or a combination of threaded connection, glue joint, clamping connection, and further, the shell of the base portion 20 and the shell of the lens barrel portion 10 can also be provided integrally by welding or casting, etc.
[0044] In some embodiments, the inside of the base portion 20 can be provided with an image sensor, which mainly functions to convert the light signal focused by the lens into an electrical signal. When light shines on the photosensitive element of the image sensor, the photosensitive element will generate an electric charge, and the amount of electric charge is proportional to the intensity of the incident light. In this way, the optical image is converted into an electrical signal image, realizing the energy conversion from light to electricity.
[0045] Further, the image sensor can further convert the electrical signal into a digital signal, so that the computer or other digital processing devices can process, store and transmit the image. The analog-to-digital conversion circuit inside the image sensor will convert the analog electrical signal generated by each photosensitive element into a digital value, which represents the brightness and color information of each pixel point in the image. The image data after digital processing can be processed by the processor of the AR glasses through various algorithms such as image enhancement, feature extraction, target recognition, etc., to provide basic image data support for the AR glasses.
[0046] In some embodiments, the first heat dissipation assembly 30 can include a first heat dissipation lens barrel assembly 31 and a second heat dissipation lens barrel assembly 32 connected to the first heat dissipation lens barrel assembly 31; wherein the first heat dissipation lens barrel assembly 31 is arranged on the side of the lens barrel portion 10, and the second heat dissipation lens barrel assembly 32 is arranged on the side of the base portion 20.
[0047] Specifically, the first heat-conductive material can include metal (such as aluminum or copper, etc.), alloy (such as aluminum alloy, etc.), and heat-dissipating graphite sheet, etc.
[0048] Preferably, the first heat dissipation component 30 can be selected from an aluminum alloy material, which has good thermal conductivity, specifically, it has a relatively high thermal conductivity coefficient, and can quickly conduct the heat generated during the operation of the camera to the outside, effectively reducing the temperature of the internal components of the camera. Further, the density of the aluminum alloy is relatively small, which can provide the camera with heat dissipation function without adding too much weight to the AR glasses, which helps to improve the comfort of the user, avoids discomfort to the user due to the heavy glasses, and affects the use experience. Further, the surface of the aluminum alloy is easy to form a dense oxide film, which can protect the aluminum alloy substrate from the erosion of the external environment, and has good corrosion resistance. Even in some relatively harsh use environments, such as humid and dusty environments, the aluminum alloy heat dissipation material can maintain good performance and is not easy to rust and damage, thereby ensuring the stability and durability of the heat dissipation effect.
[0049] In some embodiments, the second heat-conductive material can include a copper foil material, which has good ductility in addition to good thermal conductivity.
[0050] In some embodiments, the first heat dissipation lens barrel component 31 and the second heat dissipation lens barrel component 32 can be connected together by one or a combination of a threaded connection method, a glue joint connection method, and a clamping connection method. Further, the first heat dissipation lens barrel component 31 and the second heat dissipation lens barrel component 32 can also be integrated by welding or casting.
[0051] In some embodiments, the first heat dissipation lens barrel component 31 can have a sleeve structure, so that the first heat dissipation lens barrel component 31 can be sleeved on the side of the lens barrel portion 10. Specifically, the cross-sectional shape of the first heat dissipation lens barrel component 31 can be the same as the cross-sectional shape of the lens barrel portion 10, so that the first heat dissipation lens barrel component 31 can be covered on the side of the lens barrel portion 10. It should be understood that the internal size of the first heat dissipation lens barrel component 31 can be greater than or equal to the external size of the lens barrel portion 10.
[0052] It can be understood that by sleeving the first heat dissipation component 30 on the side of the first heat dissipation lens barrel component 31, when the camera is in operation, the heat generated inside the lens barrel portion 10 can be dissipated outward through the first heat dissipation lens barrel component 31, thereby playing a heat dissipation role.
[0053] In some embodiments, the second heat dissipation lens barrel assembly 32 can also be a sleeve structure, such that the second heat dissipation lens barrel assembly 32 can be sleeved on the side of the base portion 20. Specifically, the shape of the cross section of the second heat dissipation lens barrel assembly 32 can be the same as the shape of the cross section of the lens barrel portion 10, such that the second heat dissipation lens barrel assembly 32 can be covered on the side of the base portion 20. It should be understood that the inner dimension of the second heat dissipation lens barrel assembly 32 can be greater than the outer dimension of the base portion 20.
[0054] It can be understood that when the camera is in a working state, the heat generated by the image sensor inside the base portion 20 can also be dissipated outward along the side of the base portion 20, and the heat can be emitted outward by the second heat dissipation lens barrel assembly 32.
[0055] In some embodiments, the second heat dissipation assembly 40 can be arranged on the first side 21 of the bottom portion, wherein the material of the second heat dissipation assembly 40 can be a material such as copper foil material having ductility and good heat dissipation performance. The second heat dissipation assembly 40 can be connected with the first side 21 of the bottom portion by means of gluing or threaded connection.
[0056] It can be understood that when the camera is in a working state, the heat generated by the image sensor inside the base portion 20 can also be transmitted outward through the second heat dissipation assembly 40 on the first side 21 of the bottom portion, thereby playing a role in heat dissipation.
[0057] It should be understood that when the camera is in a working state, the base portion 20 is the main source of heat, especially the image sensor inside the base portion 20, which can generate a large amount of heat in the working chamber. Therefore, by arranging the second heat dissipation lens barrel assembly 32 and the second heat dissipation assembly 40, the heat dissipation area of the base portion 20 can be increased, and the heat generated by the base portion 20 can be dissipated outward through the second heat dissipation lens barrel assembly 32 and the second heat dissipation assembly 40, thereby improving the heat dissipation efficiency. Further, by abutting the second side of the base portion against the stepped portion, the movement of the base portion along the axis direction of the lens barrel portion can be limited, thereby achieving the effect of fixing the base portion and the lens barrel portion.
[0058] Through the scheme of the present application, when the camera is in a working state, the heat generated inside the lens barrel portion 10 can be transmitted outward through the first heat dissipation lens barrel assembly 31. The heat generated by the image sensor inside the base portion 20 can be dissipated outward through the second heat dissipation lens barrel assembly 32 and the second heat dissipation assembly 40. By arranging the first heat dissipation assembly 30 and the second heat dissipation assembly 40, the heat dissipation efficiency of the camera can be improved, thereby avoiding the damage of the camera due to high temperature.
[0059] Figure 2An exemplary structural diagram of a camera structure for an electronic device is shown to illustrate some other embodiments of the present disclosure. As shown in Figure 2 The camera structure can include a lens barrel portion 10, a base portion 20, a first heat dissipation assembly 30, and a second heat dissipation assembly 40. The base portion 20 can include a first bottom side 21 facing away from the lens barrel portion 10 and a second bottom side 22 facing towards the lens barrel portion 10. Further, the first heat dissipation assembly 30 includes a first heat dissipation lens barrel assembly 31 and a second heat dissipation lens barrel assembly 32.
[0060] In some embodiments, the second heat dissipation lens barrel assembly 32 forms a step portion 33 with the first heat dissipation lens barrel assembly 31, and the second bottom side 22 of the base portion 20 abuts against the step portion 33.
[0061] In some embodiments, the first heat dissipation lens barrel assembly 31 can have an inner dimension smaller than that of the second heat dissipation lens barrel assembly 32, and a step portion 33 can be formed in a transition region where the first heat dissipation lens barrel assembly 31 and the second heat dissipation lens barrel assembly 32 are connected.
[0062] In some embodiments, a first surface 331 of the step portion 33 can be a side facing towards the base portion, and further, the first surface 331 can be perpendicular to the axis of the lens barrel portion. When the first heat dissipation assembly 30 is mounted on the camera structure, the side of the lens barrel portion 10 can abut against the inner side of the first heat dissipation lens barrel assembly 31, the side of the base portion 20 can abut against the inner side of the second heat dissipation lens barrel assembly 32, and the second bottom side 22 of the base portion 20 can abut against the first surface 331 of the step portion 33. It can be understood that the first surface 331 of the step portion 33 can limit the first heat dissipation assembly 30 in the axial direction.
[0063] When the camera of the AR glasses is in operation, a large amount of heat can be generated in the image sensor inside the lens barrel portion. At this time, the heat can be dissipated outwardly through the second heat dissipation lens barrel assembly, and also through the step portion 33, so as to improve the heat dissipation efficiency of the camera.
[0064] Through the scheme of the present disclosure, the heat generated by the image sensor can be dissipated outwardly through the first heat dissipation assembly, and the heat dissipation efficiency can be improved. Further, through the arrangement of the step portion and the second heat dissipation assembly, the camera structure can be limited, so as to avoid the shaking of the camera due to the relative displacement between the first heat dissipation assembly and the lens barrel portion, and further, the situation of the decline of the shooting quality due to the shaking of the camera can be avoided.

[0066] In some embodiments, the outer side of the first heat dissipation lens barrel assembly 31 is formed with a protruding ring 311 for limiting the camera structure.
[0067] In some embodiments, the electronic device includes a mounting through hole, and the first heat dissipation lens barrel assembly 31 is mounted on the mounting through hole, wherein the size of the mounting through hole is greater than or equal to the size of the first heat dissipation lens barrel assembly 31, and the size of the mounting through hole is less than the size of the protruding ring 311.
[0068] In some embodiments, when the electronic device is an AR glasses, the AR glasses can further include a frame 60, and the camera structure can be mounted on the frame 60. Specifically, the frame 60 can be provided with a mounting through hole, and the cross-sectional shape of the mounting through hole can be the same as the cross-sectional shape of the first heat dissipation lens barrel assembly 31. The internal size of the mounting through hole can be greater than or equal to the external size of the first heat dissipation lens barrel assembly 31, and the internal size of the mounting through hole can be less than the external size of the protruding ring 311. When the cross-sectional shape of the mounting through hole and the cross-sectional shape of the first heat dissipation lens barrel assembly 31 are both circular, the internal size of the mounting through hole can be the inner diameter of the mounting through hole, and the external size of the first heat dissipation lens barrel assembly 31 can be the outer diameter thereof.
[0069] In some embodiments, when the AR glasses are in a wearing state, on the outer side of the first heat dissipation lens barrel assembly 31, the area located in the direction away from the human eye of the protruding ring 311 can form a first lens barrel area 3111, and the area located in the direction toward the human eye of the protruding ring can form a second lens barrel area 3112. In some embodiments, when the camera structure is mounted on the frame 60 of the AR glasses, the inner wall of the mounting through hole of the frame can be bonded together with the first lens barrel area 3111 of the first heat dissipation lens barrel assembly 31. Further, the side wall of the protruding ring 311 can abut against the side of the mounting through hole toward the base part 20.
[0070] By providing the protruding ring of the first heat dissipation lens barrel assembly, the camera structure can be limited, so that the camera structure can be prevented from moving in the direction along the lens barrel axis, thereby improving the accuracy of the camera shooting.

[0073] In some embodiments, the electronic device includes a third protrusion 71 extending along the axis of the lens barrel portion, when the camera structure is mounted on the electronic device, the third protrusion is connected with the limiting groove 411 to limit the camera structure. In some embodiments, the third protrusion 71 can be formed on the frame of the electronic device.
[0074] In some embodiments, the second heat dissipation lens barrel assembly 32 can be covered on the side of the base portion, and the second heat dissipation assembly 40 can be arranged on the bottom of the base portion away from the lens barrel portion.
[0075] In some embodiments, the side of the second heat dissipation lens barrel assembly 32 can be parallel to the axis of the lens barrel portion, and the side of the second heat dissipation lens barrel assembly 32 can include a first region and a second region 3212, which can be arranged at intervals. Further, the second heat dissipation assembly 40 can include a second heat dissipation main portion 4111 and a second heat dissipation auxiliary portion 4112, wherein the second heat dissipation main portion 4111 can be covered on the side of the base portion away from the lens barrel portion, and can be in abutment with the image sensor inside the base portion, so that the heat generated by the image sensor can be dissipated outwardly through the second heat dissipation main portion.
[0076] In some embodiments, one end of the second heat dissipation auxiliary portion 4112 can be connected with the second heat dissipation main portion 4111, and the other end of the second heat dissipation auxiliary portion 4112 can be arranged on the first region and extend towards the lens barrel portion, so that the second heat dissipation auxiliary portion 4112 can be in contact with the side of the second heat dissipation lens barrel assembly 32. It can be understood that through the design of the second heat dissipation auxiliary portion 4112, the heat of the bottom of the base portion 20 can be transmitted to the second heat dissipation assembly 40, and then the heat can be transmitted to the side of the second heat dissipation lens barrel assembly 32 through the second heat dissipation auxiliary portion 4112 of the second heat dissipation assembly 40, so that the efficiency of heat dissipation can be improved.
[0077] In some embodiments, a plurality of first protrusions 41 parallel to each other can be formed on the second region, and the plurality of first protrusions 41 can form one or more limiting grooves 411.
[0078] In some embodiments, the first protrusions 41 can extend along a direction parallel to the axis of the lens barrel portion, and the first protrusions can also extend along a direction inclined to the lens barrel portion.
[0079] In some embodiments, the AR glasses can further include a lens holder 70 connected to the frame, and the lens holder 70 can be arranged in an inclined manner or a vertical manner with respect to the frame. Further, the lens holder can be provided with third protrusions 71 corresponding to the aforementioned limiting grooves 411, and when the camera structure is mounted on the AR glasses, the third protrusions 71 can extend into the limiting grooves 411, thereby limiting the movement of the camera structure in a direction perpendicular to the axis of the lens barrel portion.
[0080] Through the scheme of the present application, the movement of the camera mounting structure in a direction perpendicular to the axis of the lens barrel portion can be limited, thereby improving the stability of the camera shooting.

As Figure 4c shown, in some embodiments, the second heat dissipation lens barrel assembly 32 is formed with second protrusions 3214 towards the direction away from the lens barrel portion 10.
[0082] In some embodiments, the side of the second heat dissipation lens barrel assembly 32 away from the lens barrel portion 10 can be a first limiting surface 3213, and the first limiting surface 3213 can be formed with second protrusions 3214.
[0083] In some embodiments, the plurality of first protrusions 41 and the plurality of limiting grooves 411 form a plurality of lug structures, wherein the plurality of lug structures at least include a first lug structure 43 and a second lug structure 44, the first lug structure 43 is formed with second protrusions 3214 towards the direction away from the lens barrel portion 10, and the radial dimension of the first lug structure 43 is greater than the radial dimension of the second lug structure 44.
[0084] In some embodiments, the lug structure can have a first limiting surface 3213 perpendicular to the axis of the lens barrel portion and towards the side away from the lens barrel portion.
[0085] In some embodiments, the first lug structure 43 and the second lug structure 44 can be formed on the same side of the second heat dissipation lens barrel assembly 32, or on different sides. Preferably, the first lug structure 43 and the second lug structure 44 can be formed on opposite sides of the second heat dissipation lens barrel assembly 32, respectively, and the radial dimension of the first lug structure 43 is greater than that of the second lug structure 44, which can save installation space when the camera structure is mounted on the AR glasses.
[0086] In some embodiments, the radial dimension of the first lug structure 43 is greater than that of the second lug structure 44, and the area of the first limiting surface 3213 of the first lug structure 43 can be greater than that of the second lug structure 44. Specifically, the distance from the limiting groove of the first lug to the side of the second heat dissipation lens barrel assembly 32 where the first lug is located can be greater than the distance from the limiting groove of the second lug to the side of the second heat dissipation lens barrel assembly 32 where the second lug is located. Further, the distance between the two first protrusions forming the first lug can be greater than the distance between the two first protrusions forming the second lug.
[0087] In some embodiments, a second protrusion 3214 can be formed on the first limiting surface 3213 of the first lug structure 43, facing away from the lens barrel portion 10.
[0088] It can be understood that by increasing the area of the first limiting surface 3213 of the first lug structure 43, the second protrusion 3214 can be formed on the first lug structure 43, and the space occupied by the second lug structure 44 can be reduced, thereby saving the space of the electronic device in which the camera structure is installed, improving the space utilization, and facilitating miniaturization design.
[0089] When the camera structure is mounted on the AR glasses, the outer side of the first heat dissipation lens barrel assembly 31 of the camera structure can be mounted in the through hole on the frame of the AR glasses by bonding, and the inner side of the first heat dissipation lens barrel assembly 31 can be connected together by threads and the lens barrel portion.
[0090] Further, the second heat dissipation lens barrel assembly 32 can be covered on the side of the base portion 20, and the second heat dissipation assembly 40 can be arranged on the side of the base portion 20 away from the lens barrel portion.
[0091] Further, on the side of the second heat dissipation assembly 40 away from the lens barrel portion, the frame of the AR glasses can further be formed with a second limiting surface 72, and a second groove 3215 opposite to the second protrusion 3214 can be formed on the second limiting surface 72, wherein the size of the second groove 3215 is greater than or equal to the size of the second protrusion 3214, and when the camera structure is mounted on the AR glasses, the axis of the second groove 3215 and the second protrusion 3214 coincide, so that the second protrusion 3214 can extend into the second groove 3215 to achieve the positioning effect.
[0092] It can be understood that when the cross section of the lens barrel portion, the base portion, the first heat dissipation assembly and the second heat dissipation assembly of the camera structure is a symmetrical shape, and the plurality of first protrusions are arranged obliquely relative to the axis, when the camera structure is mounted on the AR glasses, the oblique directions of the first protrusions and the limiting grooves can be different, thereby causing the installation to fail. At this time, the camera structure needs to be rotated along its axis so that the oblique directions of the first protrusions and the limiting grooves are the same, so that the installation can be started. When the second protrusion is provided, by extending the second protrusion 3214 into the second groove 3215, the oblique directions of the first protrusions and the limiting grooves are the same, so that the installation direction of the camera structure can be determined. By providing the second protrusion and the second groove, the installation efficiency of the camera structure can be improved.
[0093] Figure 5 An exemplary structural diagram of the first heat dissipation assembly 30 of some embodiments of the present disclosure is shown. As shown in Figure 5 The camera structure can include a lens barrel portion, a base portion, a first heat dissipation assembly 30 and a second heat dissipation assembly, wherein the base portion can include a first bottom side and a second bottom side, the first bottom side being a side away from the lens barrel portion, and the second bottom side being a side towards the lens barrel portion. Further, the first heat dissipation assembly 30 includes a first heat dissipation lens barrel assembly 31 and a second heat dissipation lens barrel assembly 32.
[0094] In some embodiments, the camera structure further includes a circuit assembly arranged on the side of the base portion away from the lens barrel portion, and a groove 321 extending along the axis perpendicular to the lens barrel portion is formed on the second heat dissipation lens barrel assembly 32, and the circuit assembly is at least partially arranged in the groove 321.
[0095] In some embodiments, the inner side of the first heat dissipation lens barrel assembly can be provided with a first thread, and the outer side of the lens barrel portion can be provided with a second thread opposite to the first thread, wherein the size of the first thread and the second thread is equal, and the directions are the same. The first lens barrel assembly and the lens barrel portion can be connected together through the first thread and the second thread.
[0096] In some embodiments, the circuit assembly can include a flexible printed circuit (FPC) that can efficiently connect various electronic components in the AR glasses, such as a camera, a voice recognition module, a display screen, a sensor, a processor, and the like, to work in coordination, and ensure accurate transmission of various signals, such as high-definition video, real-time sensor data, and user interaction commands.
[0097] In some embodiments, the second heat dissipation lens barrel assembly 32 can further be provided with a groove 321 on the side facing the second heat dissipation assembly, and when the second heat dissipation lens barrel assembly is arranged on the side of the base portion, the circuit assembly connected to the image sensor of the base portion can extend outward along the groove 321.
[0098] According to the scheme of the present application, the groove can provide a space for the circuit assembly, so that the distance between the circuit assembly and the base portion can be avoided to be too large, and thus the space utilization of the AR glasses can be improved.
[0099] Figure 6a An external example structural diagram of the surface temperature of the camera structure including the first heat dissipation assembly and the second heat dissipation assembly is shown. Figure 6b An internal example structural diagram of the surface temperature of the camera structure including the first heat dissipation assembly and the second heat dissipation assembly is shown. Figure 6c An external example structural diagram of the surface temperature of the camera structure without the first heat dissipation assembly and the second heat dissipation assembly is shown. Figure 6d An internal example structural diagram of the surface temperature of the camera structure without the first heat dissipation assembly and the second heat dissipation assembly is shown.
[0100] In some embodiments, as shown in Figure 6a and Figure 6b When the camera structure is externally provided with the first heat dissipation assembly and the second heat dissipation assembly, the temperature range of the camera assembly can be 38-50.5℃, which can be 38℃, 39.6℃, 41.1℃, 42.7℃, 44.2℃, 45.8℃, 47.4℃, 48.9℃, and 50.5℃, and the like. Further, the temperature of the image sensor of the camera structure can be 50.5℃.
[0101] In some embodiments, as shown in Figure 6c and Figure 6dAs shown, when the camera structure is not provided with the first heat dissipation component and the second heat dissipation component, the temperature range of the camera can be 44.6℃ to 75.7℃, which can be 44.6℃, 48.5℃, 52.4℃, 56.3℃, 60.2℃, 64.1℃, 67.9℃, 71.6℃ and 75.7℃, etc. Further, the temperature of the image sensor of the camera structure can be 75.7℃.
[0102] It can be understood that, compared to the camera structure not provided with the first heat dissipation component and the second heat dissipation component, the camera structure provided with the first heat dissipation component and the second heat dissipation component can improve the heat dissipation efficiency of the camera structure, so as to reduce the temperature of the camera structure. Especially when the image sensor is in a working state, the first heat dissipation component and the second heat dissipation component can effectively reduce the temperature of the image sensor, so as to avoid the increase of noise, color distortion and reduction of dynamic range due to the too high temperature of the image sensor, and further avoid the damage of the camera due to the too high temperature.
[0103] In some embodiments, the present application also discloses an electronic device, comprising: any camera structure as described above; and a frame, wherein the camera structure is arranged on the frame.
[0104] In summary, through the scheme of the present application, when the camera is in a working state, the heat generated inside the lens barrel part can be transferred outward through the first heat dissipation lens barrel component. The heat generated by the image sensor inside the base part can be dissipated outward through the second heat dissipation component. Through the arrangement of the first heat dissipation component and the second heat dissipation component, the heat dissipation efficiency of the camera can be improved, so as to avoid the damage of the camera due to the too high temperature.
