[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Please refer to Figures 1 to 6 The embodiment of the present application discloses a camera, which includes a housing 100 , a sensor 200 , a reflector 300 and a photosensitive chip 400 .

[0034] The housing 100 is a basic component of the camera, and is used to provide a mounting base for other components of the camera, wherein the reflector 300 and the photosensitive chip 400 are both disposed in the housing 100. In addition, the housing 100 is also used to form some functional spaces or structures, such as the light inlet 110 described later.

[0035] The sensor 200 is a core component for detecting the actual light intensity in the camera, the reflector 300 is used in the camera to transmit light by reflecting light, and the photosensitive chip 400 is a core component for realizing imaging in the camera. The housing 100 is provided with a light inlet 110, through which light can enter the housing 100, and the sensor 200 is used to detect the actual light intensity of the light entering the light inlet 110. Optionally, the sensor 200 can be arranged in the housing 100, and in order to better detect the actual light intensity of the light entering the light inlet 110, the sensor 200 can be arranged at the edge of the light inlet 110.

[0036] In the specific work process, such as Figure 2 As shown, when the actual light intensity is greater than or equal to the first light intensity threshold, the reflector 300 is used to reflect the light outside the photosensitive chip 400 to prevent the light with the actual light intensity or equal to the first light intensity threshold from being transmitted to the photosensitive chip 400 and damaging the photosensitive chip 400, thereby preventing the camera from being easily damaged when shooting in a scene with high light intensity. Figure 1 As shown, when the actual light intensity is less than the first light intensity threshold, the reflector 300 is used to reflect at least part of the light onto the photosensitive chip 400 to form an image on the photosensitive chip 400, thereby performing normal shooting.

[0037] It should be noted that the first light intensity threshold may be the limit value of the light intensity that the photosensitive chip 400 can receive. When the actual light intensity is greater than or equal to the first light intensity threshold, the photosensitive chip 400 will be burned by the light and damaged, making it difficult to use normally, resulting in defects in the imaging of the photosensitive chip 400, making it difficult to form normal images.

[0038] Optionally, at least a portion of the reflective element 300 can be movably disposed in the housing 100 so that at least a portion of the reflective element 300 can move with changes in actual light intensity, thereby being used to change the light reflected by the reflective element 300 onto the photosensitive chip 400 through corresponding movement of at least a portion of the reflective element 300.

[0039] In a specific working process, when the actual light intensity is greater than or equal to the first light intensity threshold, the reflector 300 can be used to reflect the light outside the photosensitive chip 400 by at least partially moving the reflector 300. When the actual light intensity is less than the first light intensity threshold, the reflector 300 can be used to reflect at least part of the light onto the photosensitive chip 400 by at least partially moving the reflector 300.

[0040] In one embodiment, at least a portion of the reflective member 300 can rotate as the actual light intensity changes, so that it can be used to change the light reflected by the reflective member 300 onto the photosensitive chip 400 by corresponding rotation of at least a portion of the reflective member 300, so that when the actual light intensity is greater than or equal to a first light intensity threshold, the reflective member 300 can be used to reflect the light outside the photosensitive chip 400 by at least a portion of the rotation of the reflective member 300, and when the actual light intensity is less than the first light intensity threshold, the reflective member 300 can be used to reflect at least a portion of the light onto the photosensitive chip 400 by at least a portion of the rotation of the reflective member 300.

[0041] In this structure, when the actual light intensity is less than the first light intensity threshold so that the photosensitive chip 400 can form an image, the reflector 300 can be arranged at an angle relative to the axis of the light inlet 110, and can be arranged at an angle relative to the photosensitive surface of the photosensitive chip 400. This allows the shell 100 to have reserved installation space for the above-mentioned installation method of the reflector 300, and at least part of the reflector 300 can rotate in the installation space, so that there is no need to provide additional rotation space in the shell 100 for at least part of the rotation of the reflector 300, thereby reducing the occupation of the internal space of the shell 100, which is conducive to the compact design of the camera structure.

[0042] In another embodiment, at least a portion of the reflector 300 can move with the change of the actual light intensity, so that the light reflected by the reflector 300 to the photosensitive chip 400 can be changed by corresponding movement of at least a portion of the reflector 300, so that when the actual light intensity is greater than or equal to the first light intensity threshold, the reflector 300 can be used to reflect the light outside the photosensitive chip 400 by at least a portion of the movement of the reflector 300, and when the actual light intensity is less than the first light intensity threshold, the reflector 300 can be used to reflect at least part of the light to the photosensitive chip 400 by at least a portion of the movement of the reflector 300. This structure is relatively simple and easy to implement.

[0043] The camera disclosed in the embodiment of the present application improves the structure of the camera involved in the related art, by setting a sensor 200, and setting a reflector 300 and a photosensitive chip 400 in the shell 100, so that the actual light intensity of the light entering the light inlet 110 of the shell 100 can be detected by the sensor 200, so that when the actual light intensity is less than the first light intensity threshold, the reflector 300 is used to reflect at least part of the light to the photosensitive chip 400 for normal shooting, and when the actual light intensity is greater than or equal to the first light intensity threshold, the reflector 300 can reflect the light to the outside of the photosensitive chip 400, so as to prevent the light with the actual light intensity or equal to the first light intensity threshold from being transmitted to the photosensitive chip 400 and easily damaging the photosensitive chip 400, thereby avoiding the problem of the camera being easily damaged when shooting in a scene with high light intensity.

[0044] In a further technical solution, Figure 3 As shown, when the actual light intensity is greater than or equal to the second light intensity threshold and less than the first light intensity threshold, the reflector 300 can be used to reflect part of the light outside the photosensitive chip 400 to prevent the reflector 300 from reflecting all the light onto the photosensitive chip 400, thereby weakening the light intensity projected onto the photosensitive chip 400, thereby minimizing damage to the photosensitive chip 400 and minimizing the impact on the imaging quality of the photosensitive chip 400. Figure 1 As shown, when the actual light intensity is less than the second light intensity threshold, the reflector 300 can be used to reflect the light onto the photosensitive chip 400 to form an image on the photosensitive chip 400, thereby performing normal shooting. In addition, the first light intensity threshold can be greater than the second light intensity threshold.

[0045] It should be noted that the second light intensity threshold may be a rated value of the light intensity that the photosensitive chip 400 can receive. When the actual light intensity is less than the second light intensity threshold, the photosensitive chip 400 will not be damaged by the light burns, and the photosensitive chip 400 can be used normally, so that the imaging quality of the photosensitive chip 400 will not be affected, and the photosensitive chip 400 can form images normally, that is, the second light intensity threshold may be a safe light intensity threshold. Specifically, the type of light may be light emitted by laser or fireworks, and the present application embodiment does not limit this.

[0046] In a feasible technical solution, the camera may further include a polarizing mechanism 500, which may be used to receive the light reflected by the reflector 300. Specifically, the polarizing mechanism 500 may be disposed in the housing 100, and may be disposed between the reflector 300 and the photosensitive chip 400, so as to receive the light reflected by the reflector 300, and enable at least part of the received light to pass through the polarizing mechanism 500 and be projected onto the photosensitive chip 400.

[0047] In a specific working process, when the actual light intensity is greater than or equal to the second light intensity threshold and less than the first light intensity threshold, the polarization mechanism 500 can be in a power-on state, and is used to refract part of the received light to the outside of the photosensitive chip 400, so as to further reduce the light projected onto the photosensitive chip 400, so as to further weaken the light intensity projected onto the photosensitive chip 400, and thus more effectively avoid damaging the photosensitive chip 400, so as to further avoid affecting the imaging quality of the photosensitive chip 400.

[0048] When the actual light intensity is less than the second light intensity threshold, the polarizing mechanism 500 can be in a power-off state, so that the light reflected by the reflector 300 passes through the polarizing mechanism 500 and is projected onto the photosensitive chip 400. In this case, the polarizing mechanism 500 will not affect the light reflected by the reflector 300, so that the light reflected by the reflector 300 passes through the polarizing mechanism 500 and is projected onto the photosensitive chip 400, and can be imaged on the photosensitive chip 400, so that normal shooting can be performed.

[0049] In addition, when the actual light intensity is greater than or equal to the first light intensity threshold, the reflector 300 is used to reflect the light to the outside of the photosensitive chip 400, and the photosensitive chip 400 does not perform imaging. In this case, the polarizing mechanism 500 can be in a power-off state, thereby reducing the loss of the polarizing mechanism 500, which is beneficial to reducing the loss of the camera.

[0050] In an optional technical solution, the polarizing mechanism 500 may include a first electrode layer 510, a second electrode layer 520 and a liquid crystal layer 530. The liquid crystal layer 530 may be disposed between the first electrode layer 510 and the second electrode layer 520, and may be connected to the first electrode layer 510 and the second electrode layer 520, respectively. The liquid crystal layer 530 may include a plurality of liquid crystal molecules 531. By powering on or off the polarizing mechanism 500, the distribution of the liquid crystal molecules 531 may be changed, thereby changing the refractive index of the polarizing mechanism 500. This structure is relatively light and thin, which is conducive to reducing the occupation of the internal space of the housing 100, making the structure of the camera more compact. At the same time, the cost of this structure is low, which is conducive to cost saving. Specifically, the first electrode layer 510 may be a positive electrode layer, and the second electrode layer 520 may be a negative electrode layer.

[0051] In a specific working process, when the polarizing mechanism 500 is in a powered-on state, the first electrode layer 510 and the second electrode layer 520 can be electrically conductive. Figure 6 As shown, multiple liquid crystal molecules 531 can be tilted relative to the distribution direction of the first electrode layer 510 and the second electrode layer 520, so as to refract part of the received light outside the photosensitive chip 400, thereby reducing the light projected onto the photosensitive chip 400, so as to further weaken the light intensity of the light projected onto the photosensitive chip 400.

[0052] When the polarizing mechanism 500 is in a power-off state, both the first electrode layer 510 and the second electrode layer 520 may be powered off. Figure 5 As shown, the plurality of liquid crystal molecules 531 may be perpendicular to the distribution direction of the first electrode layer 510 and the second electrode layer 520, so as to enable the light reflected by the reflector 300 to pass through the polarizing mechanism 500 and be projected onto the photosensitive chip 400, thereby preventing the polarizing mechanism 500 from affecting the light reflected by the reflector 300, so that the light reflected by the reflector 300 can form an image on the photosensitive chip 400 after passing through the polarizing mechanism 500 and being projected onto the photosensitive chip 400, thereby performing normal shooting.

[0053] Of course, in other embodiments, an optical compensation film or a polarizer may be used to refract part of the received light outside the photosensitive chip 400 when the actual light intensity is greater than or equal to the second light intensity threshold and less than the first light intensity threshold. The embodiments of the present application are not limited to this.

[0054] In the embodiment of the present application, at least a portion of the reflector 300 can be movably disposed in the housing 100, so that at least a portion of the reflector 300 can move with the change of the actual light intensity, and is used to change the light reflected by the reflector 300 to the photosensitive chip 400 through the corresponding movement of at least a portion of the reflector 300. This structure controls the direction of the light reflected by the reflector 300 by controlling the state of the reflector 300, thereby being able to efficiently adjust the light reflected to the photosensitive chip 400.

[0055] In a specific working process, when the actual light intensity is greater than or equal to the first light intensity threshold, the reflector 300 can be used to reflect the light outside the photosensitive chip 400 by at least partially moving the reflector 300, so as to prevent the light with the actual light intensity or equal to the first light intensity threshold from being transmitted to the photosensitive chip 400 and easily damaging the photosensitive chip 400. When the actual light intensity is greater than or equal to the second light intensity threshold, and less than the first light intensity threshold, the reflector 300 can be used to reflect part of the light outside the photosensitive chip 400 by at least partially moving the reflector 300, so as to reduce the light projected onto the photosensitive chip 400, thereby weakening the light intensity projected onto the photosensitive chip 400 and avoiding damage to the photosensitive chip 400. When the actual light intensity is less than the second light intensity threshold, the reflector 300 can be used to reflect the light onto the photosensitive chip 400 by at least partially moving the reflector 300, so that the photosensitive chip 400 is imaged for normal shooting.

[0056] In a further technical solution, at least part of the reflector 300 can be rotatably arranged in the housing 100, so that at least part of the reflector 300 can rotate with the change of the actual light intensity, and is used to change the light reflected by the reflector 300 to the photosensitive chip 400 by the corresponding rotation of at least part of the reflector 300. This structure changes the light reflected by the reflector 300 to the photosensitive chip 400 by rotating the reflector 300. Among them, when the actual light intensity is less than the second light intensity threshold so that the photosensitive chip 400 can form an image normally, the reflector 300 can be tilted relative to the axis of the light inlet hole 110, and can be tilted relative to the photosensitive surface of the photosensitive chip 400, so that the housing 100 has reserved an installation space for the above-mentioned installation method of the reflector 300, and at least part of the reflector 300 can rotate in the installation space, so that the housing 100 does not need to provide an additional rotation space for the rotation of at least part of the reflector 300, thereby reducing the occupation of the internal space of the housing 100, which is conducive to the compact design of the camera structure.

[0057] In a specific working process, when the actual light intensity is greater than or equal to the first light intensity threshold, the reflector 300 can be used to reflect the light outside the photosensitive chip 400 by at least partially rotating the reflector 300, so as to prevent the light with the actual light intensity or equal to the first light intensity threshold from being transmitted to the photosensitive chip 400 and easily damaging the photosensitive chip 400. When the actual light intensity is greater than or equal to the second light intensity threshold, and less than the first light intensity threshold, the reflector 300 can be used to reflect part of the light outside the photosensitive chip 400 by at least partially rotating the reflector 300, so as to reduce the light projected onto the photosensitive chip 400, thereby weakening the light intensity projected onto the photosensitive chip 400 and avoiding damage to the photosensitive chip 400. When the actual light intensity is less than the second light intensity threshold, the reflector 300 can be used to reflect the light onto the photosensitive chip 400 by at least partially rotating the reflector 300, so that the photosensitive chip 400 is imaged for normal shooting.

[0058] Of course, in other embodiments, at least a portion of the reflective element 300 can move as the actual light intensity changes, so that it can be used to change the light reflected by the reflective element 300 to the photosensitive chip 400 by corresponding movement of at least a portion of the reflective element 300. This structure is relatively simple and easy to implement.

[0059] In a specific working process, when the actual light intensity is greater than or equal to the first light intensity threshold, the reflector 300 can be used to reflect the light outside the photosensitive chip 400 by at least partially moving the reflector 300, so as to prevent the light with the actual light intensity or equal to the first light intensity threshold from being transmitted to the photosensitive chip 400 and easily damaging the photosensitive chip 400. When the actual light intensity is greater than or equal to the second light intensity threshold, and less than the first light intensity threshold, the reflector 300 can be used to reflect part of the light outside the photosensitive chip 400 by at least partially moving the reflector 300, so as to reduce the light projected onto the photosensitive chip 400, thereby weakening the light intensity projected onto the photosensitive chip 400 and avoiding damage to the photosensitive chip 400. When the actual light intensity is less than the second light intensity threshold, the reflector 300 can be used to reflect the light onto the photosensitive chip 400 by at least partially moving the reflector 300, so that the photosensitive chip 400 is imaged for normal shooting.

[0060] In an optional technical solution, the reflector 300 may include a first sub-reflector 310 and a second sub-reflector 320, and the first sub-reflector 310 and the second sub-reflector 320 may be rotatably connected, and at least one of the first sub-reflector 310 and the second sub-reflector 320 may rotate as the actual light intensity changes. In this structure, when the first sub-reflector 310 or the second sub-reflector 320 rotates, the first sub-reflector 310 rotates relative to the second sub-reflector 320, or the second sub-reflector 320 rotates relative to the first sub-reflector 310, so that the first sub-reflector 310 or the second sub-reflector 320 can occupy a smaller space when rotating, and further reduce the occupation of the internal space of the housing 100, so that the structure of the camera can be more compact.

[0061] Specifically, the first sub-reflector 310 and the second sub-reflector 320 can be a split structure, and the two can be rotatably connected through an axial hole structure. The first sub-reflector 310 and the second sub-reflector 320 can also be an integrated structure, and the two can be rotatably connected through a flexible member. The embodiments of the present application do not limit this.

[0062] As described above, in a specific working process, when the actual light intensity is greater than or equal to the first light intensity threshold, the first sub-reflector 310 and the second sub-reflector 320 can be used to reflect light outside the photosensitive chip 400 to prevent light with an actual light intensity or equal to the first light intensity threshold from being able to be transmitted to the photosensitive chip 400 and easily damaging the photosensitive chip 400.

[0063] When the actual light intensity is greater than or equal to the second light intensity threshold and less than the first light intensity threshold, at least one of the first sub-reflector 310 and the second sub-reflector 320 can be used to reflect part of the light outside the photosensitive chip 400 to prevent the reflector 300 from reflecting all the light onto the photosensitive chip 400, thereby weakening the light intensity projected onto the photosensitive chip 400, and further avoiding damage to the photosensitive chip 400 as much as possible, so as to avoid affecting the imaging quality of the photosensitive chip 400 as much as possible.

[0064] When the actual light intensity is less than the second light intensity threshold, the first sub-reflector 310 and the second sub-reflector 320 can both be used to reflect light onto the photosensitive chip 400 to form an image on the photosensitive chip 400, thereby performing normal shooting.

[0065] Optionally, the first sub-reflector 310 can be fixed in the housing 100, and the second sub-reflector 320 can be rotatably connected to the first sub-reflector 310, so that when the actual light intensity is greater than or equal to the second light intensity threshold and less than the first light intensity threshold, Figure 3 As shown, the first sub-reflector 310 can be used to reflect a portion of light onto the photosensitive chip 400, and the second sub-reflector 320 can be used to reflect another portion of light outside the photosensitive chip 400. This structure only requires the second sub-reflector 320 to rotate, and the first sub-reflector 310 is fixed in the housing 100, thereby reducing the risk of the entire reflector 300 being offset, which is beneficial to improving the reliability of the camera, and only the rotation of the second sub-reflector 320 can occupy a smaller space, thereby further reducing the occupation of the internal space of the housing 100.

[0066] In a technical solution, Figure 2 As shown, when the actual light intensity is greater than or equal to the first light intensity threshold, the first sub-reflector 310 can be used to receive a portion of the light reflected by the second sub-reflector 320, and can be used to reflect the received portion of the light reflected by the second sub-reflector 320 out of the light inlet 110, and the second sub-reflector 320 can be used to receive another portion of the light reflected by the first sub-reflector 310, and can be used to reflect the received portion of the light reflected by the first sub-reflector 310 out of the light inlet 110. This structure can reflect the light out of the light inlet 110 as much as possible, thereby avoiding the light from being reflected into the housing 100 as much as possible, causing the light to be reflected in the housing 100 and easily projected onto the photosensitive chip 400, thereby more effectively avoiding damage to the photosensitive chip.

[0067] In order to be able to more accurately control the rotation of the second sub-reflector 320, the camera may also include a driving mechanism 600 and a first transmission member 700. The driving mechanism 600 may include a connected power source 610 and a second transmission member 620. The first transmission member 700, the power source 610 and the second transmission member 620 may all be arranged in the shell 100. The power source 610 may be used to drive the second transmission member 620 to rotate. The first transmission member 700 and the second sub-reflector 320 may be connected and may be driven and connected to the second transmission member 620. The second transmission member 620 may be used to drive the second sub-reflector 320 to rotate through the first transmission member 700, so that the rotation of the second sub-reflector 320 can be accurately controlled through the power source 610, and this structure can respond quickly, which is beneficial to improving the sensitivity of the second sub-reflector 320.

[0068] The first transmission member 700 and the second transmission member 620 may be respectively a first gear and a second gear, which may be meshed and connected to each other. Of course, the first transmission member 700 and the second transmission member 620 may also be respectively a first pulley and a second pulley, which may be connected to each other via a transmission belt, and the embodiment of the present application does not limit this. In addition, the power source 610 may be a motor.

[0069] In other embodiments, the camera may further include a manual operating unit, which may be connected to the second sub-reflector 320, so that the rotation of the second sub-reflector 320 may be manually controlled through the manual operating unit. This structure is relatively simple and easy to implement, which helps to reduce costs.

[0070] In an embodiment of the present application, the camera may further include a lens 800, which may be disposed between the reflective element 300 and the photosensitive chip 400, so that when the actual light intensity is greater than or equal to the second light intensity threshold and less than the first light intensity threshold, the reflective element 300 is used to reflect part of the light into the lens 800, so that part of the light passes through the lens 800 and is projected onto the photosensitive chip 400, thereby enabling the photosensitive chip 400 to achieve imaging.

[0071] When the actual light intensity is less than the second light intensity threshold, the reflector 300 is used to reflect the light into the lens 800 so that the light passes through the lens 800 and is projected onto the photosensitive chip 400 , thereby enabling the photosensitive chip 400 to achieve imaging.

[0072] When the camera also includes a polarizing mechanism 500, the polarizing mechanism 500 can be arranged between the reflective element 300 and the photosensitive chip 400, and the lens 800 can be arranged between the polarizing mechanism 500 and the photosensitive chip 400. This structure allows a sufficient distance between the polarizing mechanism 500 and the photosensitive chip 400, so that when the actual light intensity is greater than or equal to the second light intensity threshold and less than the first light intensity threshold, the polarizing mechanism 500 in the power-on state can more easily refract part of the received light to outside the photosensitive chip 400.

[0076] Step 2: When the actual light intensity is greater than or equal to the first light intensity threshold, the reflector 300 is controlled to reflect the light outside the photosensitive chip 400;

[0077] Step three: when the actual light intensity is less than the first light intensity threshold, control the reflective element 300 to reflect at least part of the light onto the photosensitive chip 400 .

[0078] The electronic device disclosed in the embodiments of the present application may be a smart phone, a tablet computer, an e-book reader, a wearable device (such as a smart watch), an electronic game console, VR glasses, and the like. The embodiments of the present application do not limit the specific types of electronic devices.

As long as the different optimization features of the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
