[0029] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0030] In the related art, a camera module can be applied to an electronic device. The camera module is installed in a receiving cavity of a housing of the electronic device, and the receiving cavity is covered and wrapped by a pressing cover plate, such as a glass cover plate, so as to achieve the installation of the camera module. The camera module is a movable device. During the focusing process, the camera module will extend and retract the camera module to different degrees according to the distance of the focused object, so as to ensure clear photos. Therefore, sufficient preset space needs to be reserved between the camera unit of the camera module and the glass cover plate. The preset space can prevent the camera unit from hitting the internal structure of the electronic device, causing the camera module to focus blur.

[0031] Figure 1 is a structural schematic diagram of a camera module of the related technology, Figure 2 Schematic diagram of the focusing state of the camera module of the related art. Figure 1 and Figure 2 As shown, the camera module of the related art may include a housing 1 and a camera unit 2. The housing 1 is provided with a receiving cavity 11, and the housing 1 is provided with an opening 12 connected to the receiving cavity 11. A groove portion is provided at the opening 12 of the housing 1, and the camera module further includes a cover glass CG (coverglass), and the cover glass 3 is fixed to the opening 12 by gluing the groove portion. The camera unit 2 has an initial state and a focusing state. In the initial state, there is a first preset distance between the camera unit 2 and the cover glass 3. In the focusing state, there is a second preset distance between the camera unit 2 and the cover glass 3, and the first preset distance is greater than the second preset distance. That is to say, during the focusing process, the camera unit 2 will extend and retract the lens of the camera unit 2 to different degrees according to the distance of the focusing object, so that the distance between the camera unit 2 and the cover glass 3 gradually changes from the first preset distance to the second preset distance, thereby ensuring clear photography.

[0032] For example, Figure 1 As shown, the size of the reserved space 4 between the camera unit 2 and the cover glass 3 is d1, and the thickness of the cover glass 3 is d2. In the initial state and the focusing state, the camera unit 2 is located in the accommodating cavity 11. There are two parts of structural dimensions between the camera unit 2 and the housing 1. One part is the reserved space 4 to ensure safety. The size d1 of the reserved space 4 can include the focusing distance of the camera unit 2 and the assembly tolerance of the structure. The other part is the thickness d2 of the cover glass 3. Such a setting makes the thickness of the camera module larger, resulting in a thicker thickness of the entire electronic device. Moreover, if the electronic device is used for a long time, dust will enter the accommodating cavity 11 of the camera module, which may cause the lens of the camera unit 2 to be contaminated. Since the cover glass 3 covers and surrounds the accommodating cavity 11, the camera unit 2 is located in the accommodating cavity 11, which is inconvenient to clean the camera unit 2.

[0033] Exemplarily, the camera unit 2 includes a 1-inch lens, and the reserved space is determined by the focusing distance and safety space of the lens of the camera unit 2, which are 0.65 mm and 0.45 mm respectively. The thickness of the cover glass 3 is 0.5 mm, so that 1.6 mm of size is added outside the lens of the camera unit 2, thereby increasing the thickness of the electronic device by 1.6 mm.

[0034] In order to solve the problem of poor lightness and thinness of camera modules in the related art, an embodiment of the present disclosure provides a camera module. The camera module and electronic device of the embodiment of the present disclosure are described in detail below with reference to the accompanying drawings.

[0035] Figure 3 is a cross-sectional schematic diagram of a camera module according to an embodiment of the present disclosure, Figure 4 FIG. 1 is a schematic cross-sectional view of a partially focused state of a camera module according to an embodiment of the present disclosure. Figure 3 and Figure 4 As shown, the camera module of the embodiment of the present disclosure includes a housing 10 , a camera unit 20 and a telescopic film 30 .

[0036] Reference Figure 3 and Figure 4 Specifically, the housing 10 is provided with a receiving cavity 11, and the housing 10 is provided with an opening 12 communicating with the receiving cavity 11. The camera unit 20 is at least partially disposed in the receiving cavity 11. One end of the telescopic film 30 is connected to the housing 10, and the other end of the telescopic film 30 is connected to the camera unit 20. The telescopic film 30 is telescopic to change the distance that the camera unit 20 extends out of the opening.

[0037] It should be noted that the camera unit 20 is at least partially disposed in the accommodating cavity 11. For example, when the camera unit 20 is in the initial state, the camera unit 20 can be completely located in the accommodating cavity 11, so that the thickness of the camera module in the initial state can be the thinnest. Alternatively, the camera unit 20 is partially in the accommodating cavity 11, and the rest of the camera unit 20 extends out of the housing 10. In the initial state, the portion of the camera unit 20 located outside the accommodating cavity 11 should be as small as possible. The telescopic membrane 30 can be telescoped along the axial direction of the accommodating cavity 11 to change the distance that the camera unit 20 extends out of the opening 12, thereby achieving the focus of the camera module.

[0038] In the camera module of the embodiment of the present disclosure, the housing 10 is provided with a receiving cavity 11, the housing 10 is provided with an opening 12 connected to the receiving cavity 11, the camera unit 20 is at least partially arranged in the receiving cavity 11, and the telescopic film 30 can be telescopic to change the distance of the camera unit 20 extending out of the opening 12. Such a setting removes the cover glass at the position of the opening 12 in the related art, and the camera unit 20 can be more exposed outside the opening 12, reducing the thickness of the camera module. In addition, the camera module of the embodiment of the present disclosure removes the cover glass to avoid glare to a large extent. The camera unit 20 and the housing 10 are connected by the telescopic film 30, which has a simple structure and enhances the ease of use of the camera module. In addition, the user can also clearly observe the focusing action process of the camera unit 20, and the user can experience a process similar to that of a single-lens reflex camera focusing, which further improves the user experience, facilitates the cleaning of the camera unit 20, and enhances the fun of the camera module.

[0039] In one embodiment, the camera unit 20 includes a lens structure and a photosensitive structure. The light projected to the camera unit 20 passes through the lens structure and then projects to the photosensitive structure. The photosensitive structure generates an image after sensing the light. The imaging effect of the camera unit 20 can be adjusted by adjusting the composition of the lens structure, for example, negative effects such as chromatic aberration or distortion can be reduced. The photosensitive structure is a device that can convert an optical image into a digital signal. The photosensitive structure can be a metal oxide semiconductor element CMOS or an image sensor CCD.

[0040] In one embodiment, in order to protect the camera unit 20, the lens structure of the camera unit 20 can be made of glass or sapphire or transparent ceramic material to enhance the hardness of the lens of the camera unit 20 and prevent it from being broken.

[0041] For example, the housing 10 may be a rectangular, cylindrical or other shaped housing made of plastic, metal or other materials. The housing 10 only needs to be provided with a receiving cavity 11 capable of carrying the camera unit. The material and shape of the housing 10 are not specifically limited in the embodiment of the disclosure.

[0042] For example, the camera unit 20 may be located in the accommodating cavity 11, and the camera unit 20 may extend from the opening 12 of the housing 10 to a preset distance for focusing. In the initial state, the camera unit 20 may be completely hidden in the accommodating cavity 11 of the housing 10, and the top surface of the camera unit 20 is flush with the end surface of the housing 10, so that the appearance of the camera module can be more regular and the overall thickness of the camera module in the initial state can be reduced.

[0043] Exemplarily, the opening 12 may be circular, square or other shaped openings. It should be noted that the shape of the opening 12 only needs to allow the camera unit to extend out of the accommodating cavity 11 from the opening, and the shape of the opening 12 is not specifically limited in the embodiment of the disclosure.

[0044] In one embodiment, the shape of the opening 12 can be set to match the outer peripheral shape of the camera unit 20, so that the gap between the camera unit 20 and the opening 12 can be smaller, thereby preventing dust from entering the accommodating cavity 11 through the gap between the camera unit and the opening 12, thereby protecting other electrical structures located in the accommodating cavity.

[0045] Exemplarily, one end of the telescopic film 30 is connected to the housing 10, and the other end of the telescopic film 30 is connected to the camera unit 20. For example, the camera unit 20 further includes a fixing plate, the fixing plate is located outside the lens structure, one end of the telescopic film 30 is bonded to the fixing plate by glue, and the other end of the telescopic film 30 is bonded to the housing 10 by glue.

[0046] Reference Figure 3 and Figure 4 As shown, in one embodiment, the camera unit 20 has an initial state and a focus state. In the initial state, the camera unit 20 has a compressed film 30 and the camera unit 20 extends out of the opening 12 by a first preset distance. When the camera unit 20 is in the focus state, the film 30 is in an extended state and the camera unit 20 extends out of the opening 12 by a second preset distance, which is greater than the first preset distance.

[0047] Exemplarily, when the telescopic film 30 is in a compressed state, the first preset distance that the camera unit 20 extends out of the opening 12 may be equal to 0, so that the overall thickness of the camera module in the initial state is relatively small.

[0048] Exemplarily, the camera unit 20 can move along the axial direction of the accommodating cavity 11, and the telescopic film 30 is in a compressed state, and the telescopic film 30 can be curled or partially folded into a plane. When the telescopic film 30 is in an extended state, the camera unit 20 moves along the axial direction of the accommodating cavity 11 to drive the telescopic film 30 to stretch, and the telescopic film 30 can be completely or partially stretched and deformed. The elongated length of the telescopic film 30 can be determined according to the moving distance of the camera unit 20 for focusing. The camera unit 20 extends out of the opening 12 by a second preset distance, which is not limited here and can be set according to actual focusing requirements.

[0049] In the camera module of the disclosed embodiment, when the telescopic film switches from the telescopic state to the extended state, the camera unit 20 switches from the initial state to the focusing state, and the distance of the camera unit 20 extending out of the opening 12 increases from the first preset distance to the second preset distance, so that the camera unit is exposed outside the opening 12 during the focusing process, which reduces the thickness of the camera module, and the cover glass is removed at the position of the opening 12 to avoid glare. The telescopic process of the camera unit 20 can be clearly observed outside the opening 12, which improves the user experience and facilitates the cleaning of the camera unit 20.

[0050] Reference Figure 1 and Figure 2 As shown, the camera unit 2 is wrapped by the glass cover 3 in the housing 1, and there are two parts of structural space above the camera unit 2, namely, the reserved space and the structural size of the cover glass 3. Figure 4 As shown, when the camera unit 2 is focusing, the lens of the camera unit 2 extends to occupy the focusing space, leaving a safety space. Figure 1 and Figure 2 In the camera module of the related art shown, Figure 1 The overall thickness of the camera module in the unfocused state shown Figure 2 The overall thickness of the camera module in the focused state shown remains unchanged.

[0051] Reference Figure 3 and Figure 4 As shown, the embodiment of the present disclosure connects the housing 10 and the camera unit 20 via a telescopic film 30. Figure 3 The camera module is in a non-focus state, the telescopic film 30 is in a compressed state, and the thickness of the camera module reaches the thinnest state. Figure 4 The camera module is in a partially focused state, the telescopic film 30 is in a partially extended state, the camera unit 20 extends a preset distance out of the opening 12, the lens of the camera unit 20 protrudes, and the camera module is partially focused. Figure 3 and Figure 4 The camera module is relative to Figure 1 and Figure 2 The camera module of the present invention removes the glass cover plate 3, the reserved space and the focus space while ensuring the reliability of the camera module, so that the overall thickness of the camera module is reduced. Moreover, the embodiment of the present invention removes the glass cover plate 3 to avoid the glare generated by the glass cover plate. Figure 2 Focusing is performed in the accommodating cavity 11, Figure 4 The lens of the camera module can be extended to the second preset distance outside the opening 12, and the focusing process of the camera unit can be clearly seen, thereby enhancing the interest. In addition, the camera unit 20 can be extended outside the opening 12 to facilitate cleaning of the camera unit.

[0052] Reference Figure 3As shown, in one embodiment, the stretch film 30 is in a compressed state, and the stretch film 30 includes multiple layers of folds stacked together. When the stretch film 30 is in an extended state, at least one layer of the multiple layers of folds of the stretch film 30 is flattened. Exemplarily, the stretch film 30 is silicone. The use of silicone in the stretch film 30 can facilitate the formation of multiple layers of folds stacked together. When the camera unit 20 is in an initial state, each layer of folds of the stretch film 30 is tightly pressed together, and the camera unit 20 is partially or completely located in the accommodating cavity 11. At this time, the overall thickness of the camera module is minimal. During the focusing process of the camera module, the stretch film 30 is extended, and one or more layers of the folds of the stretch film 30 are flattened. For example, reference can be made to Figure 4 , the camera unit 20 is in a partial focus state, the telescopic film 30 is stretched to a certain length along the axial direction of the accommodating cavity 11 as a whole, one or more layers of the folds of the telescopic film 30 are flattened, so that the camera unit 20 extends to a second preset distance outside the opening 12, and the camera unit 20 switches to the focus state.

[0053] The stretch film 30 of the embodiment of the present disclosure is formed of multiple layers of folds by using silicone material. The stretch film 30 can be stretched from a compressed state to an extended state. The silicone material stretch film 30 also has a certain elasticity, and the stretch film 30 can be restored from an extended state to a compressed state.

[0054] Figure 5 is a cross-sectional schematic diagram of a camera module according to another embodiment of the present disclosure, Figure 6 It is a partial structural enlarged schematic diagram of the camera module of the embodiment of the present disclosure, Figure 7 It is a cross-sectional schematic diagram of the focusing state of the camera module of an embodiment of the present disclosure. Figure 6 Can be Figure 5 A partial structural enlargement diagram. Figures 5 to 7 As shown, in one embodiment, the camera module also includes a locking mechanism 40, which is used to lock the camera unit 20 when the camera unit 20 is in an initial state, or the locking mechanism 40 can also unlock the camera unit 20 when the camera unit 20 is in a focusing state.

[0055] The camera module of the disclosed embodiment locks the camera unit 20 when the camera unit 20 is in an initial state through the locking mechanism 40, and unlocks the camera unit 20 when the camera unit 20 needs to focus, thereby improving the reliability of the camera module.

[0056] In one embodiment, referring to Figures 5 to 7As shown, the housing 10, the camera unit 20 and the telescopic film 30 form a closed space, which includes a receiving cavity 11, and the locking mechanism 40 is located in the closed space. The telescopic film 30, the camera unit and the housing 10 form a closed space, which can prevent foreign objects from entering the camera unit 20 and the housing 10, thereby improving the reliability of the camera module.

[0057] Exemplarily, the camera unit 20 is located in the accommodating cavity 11, and there is a certain gap between the camera unit 20 and the accommodating cavity 11. One end of the telescopic film 30 is connected to the housing 10, and the other end of the telescopic film 30 is connected to the camera unit 20, so that the space between the camera unit and the housing 10 can be covered to form a closed space. The locking mechanism 40 is located outside the accommodating cavity, but in the closed space, so that the telescopic film 30 can further serve as a sealing protective film to prevent foreign objects from entering the housing 10.

[0058] Reference Figures 5 to 7 As shown, in one embodiment, the locking mechanism 40 includes a locking claw 41 and a locking spring 42. One end of the locking claw 41 is connected to the housing 10, and the other end of the locking claw 41 is connected to the camera unit 20. One end of the locking spring 42 is connected to the locking claw 41, and the other end of the locking spring 42 is connected to the housing 10. When the camera unit 20 is in the initial state, the locking claw 41 overlaps and locks the camera unit 20. When the camera unit 20 is in the focusing state, the locking spring 42 extends to move the locking claw to disengage from the camera unit 20 and unlock.

[0059] Exemplarily, one end of the locking jaw 41 is fixed on the end face of the housing 10, and the other end of the locking jaw 41 is suspended. The locking jaw 41 is tilted at an angle relative to the end face of the housing 10, and the two ends of the locking spring 42 are respectively connected to the locking jaw 41 and the housing 10. In the initial state of the camera unit 20, the locking jaw overlaps and locks the camera unit 20. When the camera unit 20 switches from the initial state to the focus state, the locking spring 42 stretches so that the locking jaws 41 move away from each other and break contact with the camera unit 20 to unlock. When the camera unit returns to the initial state from the focus state, the locking spring 42 resets so that the locking jaws 41 approach each other and overlap and lock the camera unit. In this way, the locking mechanism formed by the locking jaw 41 and the locking spring 42 can lock the camera unit 20 in the initial state, further improving the reliability.

[0060] Reference Figures 5 to 7As shown, in one embodiment, the locking clamp 41 includes a first end 411, an inclined section 412 and a second end 413. The first end 411 and the second end 413 are respectively arranged at the two ends of the inclined section 412, the first end 411 overlaps with the housing 10, the camera unit 20 is provided with an overlap portion 21, and the end of the housing 10 on one side of the opening 12 is provided with a bending portion 16, and a groove is formed between the bending portion 16 and the housing 10. One end of the locking spring 42 is connected to the first end 411, and the other end of the locking spring 42 is connected to the bending portion 16, and the locking spring 42 is located in the groove. When the camera unit 20 is in the initial state, the overlap portion 21 overlaps with the second end 413 to lock the camera unit 20. When the camera unit 20 is in the focusing state, the locking spring 42 extends to move the locking clamp 41 to disengage from the overlap portion 21 and unlock.

[0061] Exemplarily, the groove formed between the bending portion 16 and the shell 10 is arranged toward the side away from the accommodating cavity, and the locking spring 42 can be accommodated in the groove. One end of the first end portion 411 is connected to the locking spring 42, and the end of the first end portion 411 connected to the locking spring 42 can extend into the groove. In this way, the locking claw 41 can be driven to open or lock the camera unit through the stretching and resetting of the locking spring 42, thereby improving the reliability of the camera module.

[0062] Exemplarily, the first end 411 and the second end 413 are arranged horizontally, and the camera unit 20 further comprises a fixing plate, which is located outside the lens structure, and the fixing plate is provided with an overlap portion 21 located on the outer peripheral side. In the initial state, the overlap portion 21 overlaps with the second end 413 to lock the camera unit 20. When the camera unit moves to focus, the camera unit 20 pushes the locking claw 41 to disengage the overlap portion 21 from the second end 413, thereby unlocking the overlap portion 21 from the second end 413. The camera unit 20 extends to the second preset distance of the opening 12 to achieve focusing.

[0063] Reference Figures 5 to 7 As shown, in one embodiment, the locking mechanism 40 further includes a memory metal wire 43. The housing 10 is provided with through holes 13 located on both sides of the accommodating cavity 11, the memory metal wire 43 is located in the through holes 13, and a power contact 14 is provided on the side of the housing 10 away from the opening. The memory metal wire 43 is coupled to the power contact 14. The memory metal wire 43 includes a power-on state and a non-power-on state. In the non-power-on state, the memory metal wire 43 is relaxed. In the power-on state, the memory metal wire 43 contracts, driving the locking jaw 41 to move in the opposite direction to the elastic force of the locking spring, so that the locking jaw 41 is unlocked from the overlapping portion 21.

[0064] Exemplarily, the memory metal wire 43 is made of a material that shrinks when heated and expands when cooled.

[0065] Exemplarily, the through hole 13 is arranged along the axial direction of the accommodating cavity 11, and the distance between the first end 411 of the locking jaw 41 and the accommodating cavity 11 is smaller than the distance between the through hole and the accommodating cavity 11, that is, the through hole is arranged at the end of the locking spring 42 away from the accommodating cavity 11, so that when the memory metal wire 43 contracts, the locking spring 42 is stretched to drive the locking jaw 41 to move, thereby unlocking the locking jaw 41 and the overlapping portion 21. The camera module of the disclosed embodiment, by providing the through hole 13 and the energized contact 14, the memory metal wire 43 is arranged along the axial direction of the housing 10, and the energization and de-energization of the energized contact 14 are controlled to open or lock the locking jaw 41 of the locking mechanism 40.

[0066] In one embodiment, the material of the memory metal wire 43 is a memory metal alloy.
