[0024] First, as Figure 1 and Figure 2As shown, an embodiment of the present application provides a camera module 100, which includes a base 110, a first lens 120 and a heating mechanism 140. The base 110 includes a chamber with openings at both ends in a first direction X; the first lens 120 is connected to the base 110, and the first lens 120 is arranged in the chamber, and the first lens 120 is arranged toward the opening; the heating mechanism 140 is arranged in the chamber, and the heating mechanism 140 and the first lens 120 are thermally connected, and the heating mechanism 140 is used to adjust the temperature of the first lens 120, and the refractive index of the first lens 120 is adjustable as the temperature changes.

[0025] In the camera module 100 provided in the embodiment of the present application, the camera module 100 includes a base 110, a first lens 120 and a heating mechanism 140. The base 110 includes a cavity with openings at both ends in a first direction X. The first lens 120 and the heating mechanism 140 are arranged in the cavity. The first lens 120 and the base 110 are connected and arranged toward the opening so that external light can be incident on the first lens 120 through the opening of the base 110. The heating mechanism 140 and the first lens 120 are thermally conductively connected. The refractive index of the first lens 120 is adjustable with temperature so that the temperature of the first lens 120 is adjusted by the heating mechanism 140 to change the refractive index of the first lens 120. Through the cooperation of the heating mechanism 140 and the first lens 120, the heating mechanism 140 adjusts the temperature of the first lens 120, and the refractive index of the first lens 120 changes with the change of temperature. As the refractive index of the first lens 120 changes, the focusing function of the camera module 100 is realized. The cooperation of the heating mechanism 140 and the first lens 120 replaces the motor, simplifies the structure of the camera module 100, and the first lens 120 remains fixed relative to the base 110 during the focusing process of the camera module 100, which helps to reduce the difficulty of assembling the camera module 100 and improves the reliability of the camera module 100.

[0026] The camera module 100 also includes a photosensitive chip 150. The first lens 120 is an optical device for generating images. The photosensitive chip 150 is arranged opposite to the first lens 120. The photosensitive chip 150 is used to receive the light collected by the first lens 120 and perform photoelectric conversion to realize the recording function of the camera module 100. The photosensitive chip 150 can be a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide Semiconductor).

[0027] The camera module 100 also includes a shell, in which the first lens 120, the base 110, the heating mechanism 140 and the photosensitive chip 150 are all arranged. The shell serves to provide protection for other components of the camera module 100. A light-transmitting hole corresponding to the first lens 120 is provided on the shell, and external light can enter the first lens 120 through the light-transmitting hole; or the base 110 is reused as the shell, and the camera module 100 no longer has a separate shell, which helps to reduce the volume and material cost of the camera module 100, and facilitates heat dissipation of the first lens 120.

[0028] The first lens 120 is disposed in the cavity of the base 110 , and faces the opening of the cavity so that external light can enter the first lens 120 through the opening.

[0029] The first direction X may be the optical axis of the first lens 120 .

[0030] Optionally, the first lens 120 and the base 110 are connected by bonding or snapping.

[0031] The first lens 120 is a temperature-controlled lens. As the first lens 120 expands and contracts due to heat, the radius of curvature of the first lens 120 changes, so that the refractive index of the first lens 120 changes to adjust the focal length of the camera module 100; or as the first lens 120 changes phase, the refractive index of the first lens 120 changes to adjust the focal length of the camera module 100. Exemplarily, the first lens 120 includes thermotropic phase change materials such as vanadium dioxide and GST (Ge2Sb2Te5).

[0032] One end of the heating mechanism 140 is connected to the control mechanism, and the other end is connected to the first lens 120. When the heating mechanism 140 is powered on, the temperature rises and heats the first lens 120; when the heating mechanism 140 is powered off, the temperature of the first lens 120 drops.

[0033] For example, the heating mechanism 140 is powered on to heat the first lens 120, the temperature of the first lens 120 rises, the first lens 120 expands and the refractive index rises, the heating mechanism 140 is powered off, the heating mechanism 140 no longer heats the first lens 120, the temperature of the first lens 120 drops, the first lens 120 contracts and the refractive index drops.

[0034] Exemplarily, the heating mechanism 140 is powered on to heat the first lens 120, and the first lens 120 is heated to transform from an amorphous state to a crystalline state, and the refractive index of the first lens 120 increases. The heating mechanism 140 is powered off, and the heating mechanism 140 no longer heats the first lens 120, and the temperature of the first lens 120 decreases, the first lens 120 is transformed from a crystalline state to an amorphous state, and the refractive index of the first lens 120 decreases.

[0035] The control mechanism can adjust the current flowing into the heating mechanism 140 to control the heating rate of the first lens 120 and the focal length adjustment speed of the camera module 100. The specific current amount can be designed by the user.

[0036] Specifically, when the camera module 100 needs to focus, the control mechanism energizes the heating mechanism 140, causing the camera module 100 to obtain a first image and calculate the contrast of the first image. The heating mechanism 140 continues to heat the first lens 120, causing the camera module 100 to obtain a second image and calculate the contrast of the second image. This process continues until the heating mechanism 140 heats the first lens 120, the camera module 100 obtains the nth image, where n ≥ 2, calculates the contrast of the nth image, and compares the contrast of the first image to the nth image. The control mechanism then stabilizes the temperature of the first lens 120 at the point of highest image contrast, completing the capture. The temperature difference between two adjacent images can be flexibly designed, taking into account the energy consumption and imaging quality of the camera device.

[0037] Optionally, the user can flexibly design the operating temperature of the heating mechanism 140. For example, the heating mechanism 140 can heat the first lens 120 to above 90°C to prevent the first lens 120 from being affected by the ambient temperature and improve the reliability of the first lens 120.

[0038] The first lens 120 increases its own temperature through the heating mechanism 140 . After the heating mechanism 140 is powered off, the heat at the first lens 120 is dissipated into the environment, and the temperature of the first lens 120 decreases.

[0039] It should be clear that since the heating area and heating time of the heating mechanism 140 in the camera module 100 are relatively short, the heat generated by the heating mechanism 140 will not significantly change the overall temperature of the camera module 100 and will not affect the user of the camera module 100.

[0040] The shape of the heating mechanism 140 can be designed by oneself. For example, the heating mechanism 140 is sheet-shaped, with multiple heating sheets arranged at intervals and connected to the first lens 120; or the heating mechanism 140 is coil-shaped, with the heating coil wound around the outer circumference of the first lens 120.

[0041] Optionally, in the first direction X, the orthographic projection of the heating mechanism 140 and the first lens 120 are spaced apart to avoid the problem that the heating mechanism 140 blocks light and interferes with imaging of the camera module 100 .

[0042] In some embodiments, as Figure 1 and Figure 2As shown, the camera module 100 also includes a second lens 130, which is connected to the base 110 and arranged in the cavity. The second lens 130 and the first lens 120 are spaced apart in the first direction X so that external light can be transmitted through the second lens 130 and then transmitted to the first lens 120.

[0043] In these embodiments, the camera module 100 also includes a second lens 130 disposed in the chamber. External light passes through the second lens 130 and is transmitted to the first lens 120. The second lens 130 is used to converge light. The second lens 130 and the first lens 120 are spaced apart in the first direction X to reduce the impact of the high temperature at the first lens 120 on the second lens 130, thereby improving the imaging quality of the camera module 100.

[0044] The second lens 130 and the first lens 120 are spaced apart. External light is focused on the second lens 130 and is captured by the photosensitive chip 150 through the first lens 120 .

[0045] In the related art, a lens assembly includes multiple lenses, including ED (Extra Low Dispersion) lenses and aspherical lenses. However, in the present embodiment, since the first lens 120 and the second lens 130 for adjusting focal length are spaced apart, the number of lenses in the second lens 130 is smaller than in lens assemblies in the prior art. This reduces the manufacturing difficulty of the second lens 130 and provides more space for the first lens 120 to be installed, thereby improving the manufacturing yield of the camera module 100.

[0046] Furthermore, since the first lens 120 and the second lens 130 are spaced apart, the deformation space of the first lens 120 , that is, the focal length adjustment range of the camera module 100 is larger, and the distance between the first lens 120 and the second lens 130 can be flexibly designed.

[0047] Optionally, the second lens 130 and the base 110 are connected by snapping or bonding to improve the stability of the second lens 130 .

[0049] In some embodiments, as Figures 3 to 5As shown, the camera module 100 further includes a heat insulation layer 131 , which is disposed between the base 110 and the second lens 130 , and at least a portion of the second lens 130 is connected to the base 110 via the heat insulation layer 131 .

[0050] In these embodiments, the camera module 100 also includes a heat insulation layer 131 arranged between the base 110 and the second lens 130. At least a portion of the second lens 130 is connected to the base 110 through the heat insulation layer 131. The heat insulation layer 131 is used to reduce the heat transferred from the base 110 to the second lens 130 from the first lens 120, thereby improving the problem of deformation of the second lens 130 at high temperatures and improving the imaging quality of the camera module 100.

[0051] Optionally, the thermal insulation layer 131 extends continuously and surrounds the outer circumference of the second lens 130 to enhance the thermal insulation effect on the second lens 130. Optionally, the thermal insulation layer 131 is a flexible member. Under external force impact, the thermal insulation layer 131 acts to buffer the external force transmitted from the base 110 to the second lens 130.

[0052] Optionally, two sides of the heat insulation layer 131 are respectively bonded or snap-connected to the second lens 130 and the base 110 .

[0053] Optionally, the thermal insulation layer 131 may be thermal insulation foam or a thermal insulation adhesive layer.

[0054] See also Figure 6 , Figure 6 This is a partial structural diagram of the camera module of some embodiments of the present application.

[0055] In some embodiments, as Figure 2 and Figure 6 As shown, the heating mechanism 140 is disposed around the outer peripheral surface of the first lens 120 .

[0056] In these embodiments, the heating mechanism 140 is disposed around the outer circumference of the first lens 120 to increase the contact area between the heating mechanism 140 and the first lens 120, thereby increasing the heating rate of the first lens 120 by the heating mechanism 140 and enabling the heating mechanism 140 to uniformly heat the first lens 120, thereby improving the deformation uniformity of the first lens 120.

[0057] Optionally, the heating mechanism 140 may be a heating plate curved around the outer circumference of the first lens 120 ; or the heating mechanism 140 may be a heating coil wound around the outer circumference of the first lens 120 .

[0058] Optionally, the heating mechanism 140 is bonded to the outer peripheral surface of the first lens 120 by means of thermally conductive adhesive to improve the connection reliability between the heating mechanism 140 and the first lens 120 .

[0059] In some embodiments, as Figure 2 and Figure 6 As shown, the camera module 100 further includes a heat-conducting layer 121 , which is disposed on at least a portion of the outer peripheral surface of the first lens 120 .

[0060] In these embodiments, the camera module 100 also includes a heat-conducting layer 121 arranged on at least a portion of the outer peripheral surface of the first lens 120. The heat-conducting layer 121 improves the heat exchange rate between the first lens 120 and the external environment, thereby increasing the cooling speed of the first lens 120, thereby increasing the focusing speed of the camera module 100 and improving the user experience.

[0061] Optionally, the thermal conductive layer 121 can be a thermal conductive foam, a graphene plate, a metal plate, etc. The thermal conductivity of the thermal conductive layer 121 is greater than the thermal conductivity of the first lens 120, so as to improve the heat exchange rate between the first lens 120 and the external environment through the thermal conductive layer 121. The external environment refers to the environment outside the first lens 120.

[0062] Optionally, the heat conducting layer 121 is connected between the first lens 120 and the base 110 , so that the heat conducting layer 121 can quickly transfer the heat of the first lens 120 to the base 110 , and then conduct the heat from the base 110 to the external environment.

[0063] Optionally, multiple heat conducting members are spaced apart on the outer periphery of the first lens 120, or the heat conducting member continuously extends along the outer periphery of the first lens 120, thereby increasing the contact area between the first lens 120 and the heat conducting member, thereby enhancing the heat conducting member's effect on improving the thermal conductivity of the first lens 120. The specific area of ​​the heat conducting member can be designed by the user.

[0064] Optionally, the heat conducting member and the heating mechanism 140 are spaced apart, and the heating mechanism 140 is attached to the outer peripheral surface of the first lens 120 , so that the heat of the heating mechanism 140 is transferred to the first lens 120 more quickly.

[0065] Optionally, the heat-conducting layer 121 is also arranged on the inner surface of the cavity of the base 110, so that the heat of the first lens 120 can quickly pass through the heat-conducting layer 121 and be conducted to the external environment through the base 110, thereby accelerating the cooling rate of the first lens 120 and improving the focusing speed of the camera module 100.

[0066] In some embodiments, as Figure 2 and Figure 6 As shown, the heat-conducting layer 121 is disposed around the outer peripheral surface of the first lens 120 , and the heating mechanism 140 is surrounded on a side of the heat-conducting layer 121 away from the first lens 120 .

[0067] In these embodiments, the heat-conducting layer 121 is disposed around the outer peripheral surface of the first lens 120 and is disposed between the heating mechanism 140 and the first lens 120. The heat-conducting layer 121 is used to evenly transfer heat from the heating mechanism 140 to the first lens 120, thereby improving the deformation uniformity of the first lens 120; and increasing the contact area between the heat-conducting layer 121 and the first lens 120, thereby improving the heat dissipation rate of the first lens 120.

[0068] The heat-conducting layer 121 surrounds the entire outer surface of the first lens 120 . The heat of the heating mechanism 140 is evenly transferred to the outer surface of the first lens 120 through the heat-conducting layer 121 , thereby heating the entire first lens 120 .

[0069] Optionally, thermal conductive colloid is provided on both sides of the thermal conductive layer 121 to connect the first lens 120 and the base 110 .

[0070] See also Figure 7 , Figure 7 Exploded diagrams of camera modules according to other embodiments of the present application.

[0071] In some embodiments, as Figure 2 and Figure 7 As shown, the camera module 100 further includes a light shielding layer 122 , which is disposed around the outer peripheral surface of the first lens 120 , or the heat conducting layer 121 is a light shielding material.

[0072] In these embodiments, the camera module 100 also includes a light-shielding layer 122 arranged around the outer peripheral surface of the first lens 120 to reduce the impact of external light on the first lens 120, or the heat-conducting layer 121 is a light-shielding material, and the heat-conducting layer 121 can be reused as the light-shielding layer 122, so as to reduce the impact of external light on the first lens 120 while reducing the number of parts in the device and improving the utilization rate of the internal space of the device.

[0073] The light shielding layer 122 and the heat conducting layer 121 are provided separately and bonded to each other to block external light and improve the problem of external light interfering with the imaging of the first lens 120 .

[0074] For example, the light shielding layer 122 may be a plate-shaped or sheet-shaped light shielding member surrounding the outer periphery of the first lens 120 , or the light shielding layer 122 may be a light shielding coating disposed on the surface of the heat conducting layer 121 or the outer periphery of the first lens 120 .

[0075] Optionally, the heat conducting layer 121 is disposed on at least one side in the thickness direction of the heat conducting layer 121 .

[0076] The heat-conducting layer 121 is a light-shielding material. For example, the heat-conducting layer 121 is a black graphene heat-conducting layer 121. In addition to conducting heat between the heating mechanism 140 and the first lens 120, the heat-conducting layer 121 also blocks external light and improves the imaging quality of the first lens 120.

[0077] In some embodiments, as Figures 3 to 6 As shown, the camera module 100 further includes a temperature sensor 123 , which is disposed on the heat-conducting layer 121 and is used to obtain the temperature of the heat-conducting layer 121 .

[0078] In these embodiments, the camera module 100 further includes a temperature sensor 123 disposed on the heat conductive layer 121 so that when the temperature sensor 123 can obtain the temperature of the first lens, the temperature sensor 123 will not block the first lens, thereby avoiding a decrease in the imaging quality of the camera module 100.

[0079] The control mechanism adjusts the current applied to the heating mechanism 140 according to the temperature information obtained by the temperature sensor 123 to control the refractive index of the first lens 120 .

[0080] When the temperature sensor 123 is arranged on both sides of the first lens 120 in the axial direction, the temperature sensor 123 can accurately obtain the temperature of the first lens 120, but it will also block the first lens 120, affecting the imaging of the device; therefore, in an embodiment of the present application, the temperature sensor 123 is arranged on the heat-conducting layer 121, the heat-conducting layer 121 and the first lens 120 are connected, the temperatures of the heat-conducting layer 121 and the first lens 120 are close, the temperature of the heat-conducting layer 121 obtained by the temperature sensor 123 is close to the temperature of the first lens 120, and the temperature sensor 123 arranged on the heat-conducting layer 121 will not block the first lens 120.

[0081] Optionally, the first lens 120 and the heat-conducting layer 121 are spaced apart, and both are disposed on the peripheral surface of the first lens 120 to improve the reliability of the temperature sensor 123 .

[0082] In some embodiments, as Figure 2 As shown, the thermal conductivity of the base 110 is greater than the thermal conductivity of the first lens 120 .

[0083] In these embodiments, the thermal conductivity of the base 110 is greater than the thermal conductivity of the first lens 120, so that after the temperature of the first lens 120 is transferred to the base 110, it can be quickly transferred to the external environment, thereby increasing the cooling speed of the first lens 120 and increasing the zoom rate of the camera module 100.

[0084] Optionally, the base 110 is a metal member, and the metal base 110 has high structural strength to improve the reliability of the camera module 100. Exemplarily, the base 110 is made of aluminum or aluminum alloy or copper or copper alloy.

[0085] Optionally, the base 110 is a non-metallic part to reduce the weight of the device and improve the user experience. Exemplarily, the material of the base 110 is graphene, boron carbide, or silicon carbide.
