[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] In related technologies, electronic devices such as mobile phone cameras are prone to glare problems in strong light environments, which affects the shooting effect. Some solutions include coating the lens surface and optimizing software algorithms, but the effect of eliminating glare is not good and increases the cost and complexity.

[0032] In view of the above problems, this application provides a camera component and an electronic device, which will be described below with reference to the accompanying drawings.

[0033] Please see Figure 1 As shown, Figure 1 This is a schematic diagram of a camera assembly provided in an embodiment of this application. For example, the camera assembly 100 includes a camera 110, a mounting bracket 120, a light shield 130, and a driver 140.

[0034] The camera 110 includes a base 112 and a lens 114. The lens 114 is mounted on the base 112, which supports the lens 114 and can house electrical components related to the lens 114. For example, the base 112 can be rectangular or cubic, and the lens 114 can be cylindrical, and the lens 114 can be a variable-diameter cylinder to suit its functional requirements.

[0035] Mounting bracket 120 is used to mount the light shield 130. Mounting bracket 120 is connected to base 112 and has an opening 122 for exposing lens 114, ensuring that lens 114 can capture the image. It should be noted that, in the direction directly facing lens 114, mounting bracket 120 can be open, or in other words, the projection of mounting bracket 120 onto base 112 does not overlap with the projection of lens 114 onto base 112.

[0036] A lens hood 130 is disposed around the lens 114 and is movably connected to the mounting bracket 120. The lens hood 130 has a first state in which it is moved to be hidden within the mounting bracket 120, and a second state in which it is moved to protrude from the mounting bracket 120 to block light in the circumferential direction of the lens 114. For example, the lens hood 130 may be annular, and the inner diameter of the lens hood 130 may be larger than the outer diameter of the lens 114, which can prevent the lens hood 130 from interfering with or hindering the operation of the lens 114.

[0037] The driving component 140 is connected to the light shield 130 via a transmission connection, and the driving component 140 is used to drive the light shield 130 to move. The transmission connection can be understood as connecting the driving component 140 and the light shield 130 respectively through a transmission structure as an intermediate connecting component.

[0038] In the camera assembly 100 provided in this application embodiment, by setting the light shield to a liftable form and raising the light shield when the lens is shooting, the light around the lens is effectively blocked, creating good lighting conditions for shooting, which can reduce glare problems and does not require complex algorithm processing.

[0039] It should be noted that the light shield 130 is mainly used to partially block the light from the lens 114 of the camera 110. Therefore, the light shield 130 is defined as part of the camera assembly 100, but this does not limit the application scope of the light shield 130. In some other embodiments, the light shield 130, as well as the mounting bracket 120 and the drive component 140, can also be used as a separate light shield assembly. In order to be compatible with other components, the mounting bracket 120 can also be modified accordingly.

[0040] For example, in the direction away from the base 112, the lens 114 is flush or nearly flush with the mounting bracket 120, which can reduce or avoid the influence of the mounting bracket 120 on the light of the lens 114 when the ambient light is normal or not strong.

[0041] Please combine Figure 1 And see Figure 2 As shown, Figure 2 This is a structural block diagram of a camera assembly provided in an embodiment of this application. Exemplarily, the camera assembly 100 further includes a controller 150, which is electrically connected to the lens 114 and the drive unit 140. The controller 150 is configured to generate a first drive signal based on a start signal from the lens 114, and drive the light shield 130 to move to a position protruding from the mounting bracket 120 via the drive unit 140. The controller 150 is also configured to generate a second drive signal based on a stop signal from the lens 114, and drive the light shield 130 to move to a position hidden within the mounting bracket 120 via the drive unit 140.

[0042] It should be noted that the controller 150, also known as the control circuit, is the core control component for the lifting and lowering movement of the light hood 130. The controller 150 coordinates the work of various components to achieve precise control over the lifting and lowering of the light hood 130. The controller 150 can detect and process signals. When the camera 110 is activated, the electronic device sends a start signal. Upon receiving this signal, the controller 150 detects and processes it to confirm that it is a command to activate the camera 110. Similarly, when shooting ends, the electronic device sends an end signal, which the controller 150 accurately recognizes. The controller 150 can also generate drive signals. Upon receiving the camera 110 start signal, the controller 150 generates a corresponding drive signal and transmits it to the drive component 140, causing the drive component 140 to rotate in a predetermined direction and speed, thus raising the light hood 130. When the shooting ends signal arrives, the controller 150 changes the drive signal, causing the drive component to rotate in the opposite direction, lowering the light hood 130.

[0043] In order to ensure the stable operation of the control circuit, overcurrent protection and overvoltage protection circuit modules are also designed. These protection modules can automatically cut off the power supply or take corresponding protective measures when abnormal conditions occur in the circuit, so as to prevent the drive component 140 and other circuit components from being damaged due to overload or overvoltage, thereby improving the reliability and service life of the entire system.

[0044] The light hood 130 is a component that directly provides light protection. Its shape and size are designed according to the specific specifications of electronic devices such as mobile phone cameras. The light hood 130 can be made of opaque materials, such as black plastic or black metal, to effectively block external light from interfering with camera shooting and improve image quality. The part of the light hood 130 that connects to the transmission device is specially designed and processed to ensure a firm and reliable connection with the transmission device, enabling accurate transmission of motion and force.

[0045] It should be noted that the height of the lens hood 130 is less than the height of the lens 114. The distance by which the lens hood 130 protrudes from the mounting bracket 120 can be the height of the lens hood 130. For example, the bottom of the lens hood 130 can be flush with the top of the mounting bracket 120 to prevent gaps between them from affecting the light-blocking effect. This setting makes it easier to control the raising of the lens hood 130 without complicated calculations, which simplifies the program design.

[0046] In some embodiments, the distance by which the light shield 130 extends beyond the mounting bracket 120 can be determined according to the intensity of the ambient light. For example, when the ambient light intensity is high, the light shield 130 can be moved to a position where its bottom is flush with the top of the mounting bracket 120; when the ambient light intensity is moderate, the light shield 130 can be moved to a position where it protrudes at least half the height of the mounting bracket 120; and when the ambient light is weak, the light shield 130 can be moved to a position where it is hidden inside the mounting bracket 120.

[0047] For example, please refer to Figure 3 , Figure 3 This is an exploded structural diagram of a portion of the camera assembly provided in an embodiment of this application. The transmission connection between the drive member 140 and the light shield 130 can be achieved using a transmission device. For example, the camera assembly 100 further includes a first transmission member 162 and a second transmission member 164. The first transmission member 162 is fixedly connected to the light shield 130, and the second transmission member 164 is fixedly connected to the drive member 140. The second transmission member 164 is rotatably connected to the first transmission member 162 to transmit the driving force of the drive member 140 to the light shield 130.

[0048] Among them, the driving component 140 can be a micro motor. The micro motor serves as the power source for the lifting and lowering of the entire sunshade 130. It has the characteristics of small size, low energy consumption, and fast response speed, which can meet the requirements of compact internal space and strict energy consumption control of electronic devices such as mobile phones. The micro motor generates rotational power by receiving electrical signals from the controller 150.

[0049] In order to make the movement of the sunshade 130 more stable, micro motors can be set on opposite sides of the sunshade 130, and correspondingly, two pairs of first transmission components 162 and second transmission components 164 can be set to cooperate.

[0050] A transmission device connects the drive component 140 (i.e., the micro motor) and the sunshade 130, converting the rotational motion of the micro motor into the linear lifting motion of the sunshade 130. The transmission device can be a rack and pinion mechanism, such as a rack as the first transmission component 162 and a gear as the second transmission component 164. A drive gear is mounted on the output shaft of the micro motor, and a rack that meshes with the drive gear is fixedly connected to the sunshade 130. When the micro motor drives the drive gear to rotate, the gear's rotation, through meshing with the rack, pushes the rack to move in a certain direction, thereby raising and lowering the sunshade. Alternatively, a screw and nut transmission mechanism can be used, such as a nut as the first transmission component 162 and a screw as the second transmission component 164. The micro motor drives the screw to rotate, and the nut on the screw is connected to the sunshade 130. As the screw rotates, the nut moves linearly along the screw, thus raising and lowering the sunshade 130.

[0051] Please see Figure 4 As shown, Figure 4 This is an exploded view of the camera assembly provided in an embodiment of this application. To reduce swaying or displacement during the raising and lowering of the light shield 130, a guide rail can be provided to guide the movement of the light shield 130. For example, the mounting bracket 120 is provided with a guide rail 124. It should be noted that this embodiment of the application describes the guide rail 124 as part of the mounting bracket 120, or in other words, the guide rail 124 is integrally formed with a portion of the mounting bracket 120 during manufacturing. However, this does not limit the guide rail 124 to being only part of the mounting bracket 120; in other embodiments, the guide rail 124 may be provided independently of the mounting bracket 120.

[0052] The camera assembly 100 also includes a slide bar 170, with both ends of the slide bar 170 abutting against the guide rail 124. A drive component 140 is mounted on the slide bar 170, so that the drive component 140 moves along with the light shield 130 when it is raised or lowered, and is guided by the slide bar 170, thereby enabling the linear movement of the light shield 130.

[0053] It should be noted that the guide rail 124 provides guidance for the lifting and lowering of the sunshade 130, ensuring that the sunshade 130 can move along a predetermined straight line during the lifting and lowering process without wobbling or deviation. The guide rail 124 is usually made of high-precision metal or plastic materials, which have good wear resistance and smoothness. The installation position of the guide rail 124 is precisely matched with the interior of the sunshade 130 and the mounting bracket 120, ensuring that the sunshade 130 maintains a suitable clearance with surrounding components during the lifting and lowering process, avoiding collisions or friction.

[0054] For example, the mounting bracket 120 includes a bottom wall 126, a top wall 127, and four uprights 128. The bottom wall 126 and the top wall 127 are arranged opposite each other, and both the bottom wall 126 and the top wall 127 have openings 122 to avoid obstructing the lens 114. The four uprights 128 are arranged between the bottom wall 126 and the top wall 127, and at the four corners of the bottom wall 126 and the top wall 127, which can provide support and save materials. The guide rail 124 can be arranged on the uprights 128, which can save materials and eliminate the need for positioning installation.

[0055] The light shield 130 in the camera assembly 100 of this application embodiment has two usage states. Please refer to... Figures 1 to 4 And see Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram of the first usage state of the camera assembly provided in an embodiment of this application. Figure 6This is a schematic diagram of the second usage state of the camera assembly provided in this application embodiment. The first usage state is the raised state. When the electronic device activates the camera 110 function, the controller 150 receives the corresponding activation signal and generates a drive signal to make the drive component 140 rotate. The drive component 140 drives the light shield 130 to move upward along the guide rail 124 through the transmission device until it reaches the predetermined raised position. During this process, the light shield 130 gradually rises, effectively blocking the light around the camera 110, i.e., the lens 114, creating good lighting conditions for the lens 114 to take pictures.

[0056] The second usage state is the lowered state. After the shooting ends, the electronic device sends an end signal. After receiving the end signal, the controller 150 changes the drive signal of the drive component 140, causing the drive component 140, such as a micro motor, to rotate in the opposite direction. Through the transmission device, the light hood 130 moves downward along the guide rail 124 and finally returns to its initial position, that is, the position hidden inside the mounting bracket 120. At this time, the light hood 130 no longer blocks the lens 114 and does not affect other normal functions of the electronic device. At the same time, it also avoids the light hood 130 occupying extra space when not in use.

[0057] In the camera assembly 100 of this application embodiment, through the coordinated work of the driving component 140 such as a micro motor, the transmission device such as the first transmission component 162 and the second transmission component 164, the controller 150, and the light shield 130, the stable lifting and lowering of the light shield 130 around the electronic device camera 110 is realized, which effectively solves the problem of light interference when the camera 110 is shooting, improves the shooting quality, and does not require complicated program processing.
