Technical Field

[0001] This application relates to the technical field of terminal devices, and particularly to a learning machine. Background Art

[0002] The camera of a learning machine is usually arranged on the back of the learning machine. When the camera is used to photograph the front environment of the learning machine, the camera needs to rotate a large angle. The movement range of the camera is large, and the area of the camera exposed to the air is large, making it easy to be damaged by collision. Moreover, when the camera is located on the back of the learning machine, the camera faces away from the housing, and the camera can still photograph the surrounding environment of the learning machine, which is not conducive to protecting the privacy of users. Summary of the Invention

[0003] The purpose of this application is to provide a learning machine to solve the problems that the camera component of the learning machine requires a large space when rotating, the damage probability of the camera component is high, and the privacy of users cannot be protected.

The camera component includes a camera. When the camera component is in the storage position, the camera faces the groove wall of the receiving groove. When the camera component is in the shooting position, the camera can photograph an object located in front of the display screen and below the camera component.

[0005] The beneficial effects of this application are as follows: By rotatably installing the camera component in the receiving groove on the front surface of the housing, the learning machine requires a small space when the camera component rotates, and the learning machine is more flexible to use.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations. In addition, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

The character " / " generally represents an "or" relationship between the associated objects before and after.

[0033] Unless otherwise defined, all the technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] The learning machine can be connected to input devices (such as a mouse, keyboard, etc.), a bracket, and a playback device (such as a speaker, etc.). The learning machine can be a tablet computer, a mobile phone, a display screen, etc.

[0035] The following describes the usage scenarios of the learning machine by way of example:

[0036] When the user is studying, a reading material (such as a book, a test paper, etc.) can be placed on a support (such as a desk, a coffee table), and then the learning machine is placed on the same support. The learning machine is supported and erected, the screen of the learning machine faces the user, the learning machine can be set to be inclined relative to the upper surface of the support, the screen of the learning machine gradually moves away from the user from bottom to top, the reading material is located in front of the learning machine, the learning machine has a camera, the camera is located above the reading material, and the user can control the camera to face the reading material to take pictures and identify the content on the reading material. The content captured by the camera can be displayed on the display screen, and the user clicks on the display screen to study, explain, or interpret the relevant content.

[0037] The inventors of the present application have found that: in the learning machines in the related art, the camera assembly is usually arranged on the back of the housing. When it is necessary to photograph the scene in front of the learning machine, the camera assembly needs to be flipped from the rear side of the housing to the front side. The required movement range of the camera assembly is large. When the camera assembly is flipped to the front of the learning machine, the camera assembly is exposed outside the housing, and the probability of the camera assembly being knocked and damaged is high. Especially when the learning machine falls, the camera assembly may directly contact the ground, and the camera assembly is easily damaged. Moreover, when the camera assembly is located on the back of the housing, the camera of the camera assembly still faces outward, and it will continuously photograph the surrounding scenes, which is not conducive to protecting the privacy of users.

[0038] Based on the above findings, the inventors of the present application have improved the above problems by arranging the camera assembly 300 on the front of the housing 100 of the learning machine 1 to reduce the space required for the rotation of the camera assembly 300. Moreover, a receiving groove 120 is provided on the front of the housing 100, and the camera assembly 300 is placed in the receiving groove 120. The groove wall of the receiving groove 120 is used to block the camera assembly 300, reducing the damage probability of the camera assembly 300. Even when the learning machine 1 falls, the probability that the camera assembly 300 directly contacts the ground is low, and the camera assembly 300 is not easily damaged. In addition, when the camera 330 of the camera assembly 300 faces the groove wall of the receiving groove 120, the camera 330 cannot photograph the environment outside the receiving groove 120, which can protect the privacy of users.

[0039] The following describes the learning machine 1 according to an embodiment of the present application with reference to the drawings.

[0040] Please refer to Figures 1 to 4, the learning machine 1 according to the embodiments of the present application includes a housing 100, a display screen 200, and a camera assembly 300.

[0041] The housing 100 has a front surface 110, and a receiving groove 120 is provided on the front surface 110. The display screen 200 is disposed on the front surface 110, and the camera assembly 300 is rotatably disposed on the front surface 110 between a storage position and a shooting position. The camera assembly 300 includes a camera 330. When the camera assembly 300 is in the storage position, the camera 330 faces the groove wall of the receiving groove 120. When the camera assembly 300 is in the shooting position, the camera 330 can shoot an object located in front of the display screen 200 and below the camera assembly 300. The object can be a reading material, a picture album, or other works with image content for taking pictures, or a person located in front of the learning machine 1 for taking pictures.

[0042] It should be noted that the housing 100 has a front surface 110 and a back surface 150. The front surface 110 and the back surface 150 can be located on opposite sides in the thickness direction of the housing 100. The front surface 110 is used to mount the display screen 200. When the learning machine 1 is in use, the front surface 110 faces the user, facilitating the user to view and operate the display screen 200.

[0043] According to the learning machine 1 of the embodiments of the present application, by rotatably disposing the camera assembly 300 on the front surface 110 and disposing the display screen 200 on the front surface 110, that is to say, the camera assembly 300 and the display screen 200 are located on the same side of the housing 100.

[0044] In addition, a receiving groove 120 is provided on the front surface 110. The camera assembly 300 is rotatably disposed in the receiving groove 120 between a storage position and a shooting position. The camera assembly 300 includes a camera 330. When the camera assembly 300 is in the storage position, the camera 330 faces the groove wall of the receiving groove 120; when the camera assembly 300 is in the shooting position, the camera 330 faces the groove opening of the receiving groove 120.

[0045] In this way, when the camera assembly 300 is located in the receiving groove 120, the groove wall of the receiving groove 120 can block the camera assembly 300 to reduce the exposed surface area of the camera assembly 300, thereby reducing the probability of the camera assembly 300 being knocked. Even when the learning machine 1 falls, the probability that the camera assembly 300 directly contacts the ground is low, and the damage probability of the camera assembly 300 is also reduced accordingly.

[0046] When the camera module 300 is in the storage position, the camera 330 of the camera module 300 faces the wall of the receiving groove 120. The content captured by the camera 330 is the wall of the receiving groove 120, and information outside the receiving groove 120 will not be captured, preventing the leakage of user privacy. When the camera module 300 is in the shooting position, the camera 330 faces the opening of the receiving groove 120, and the camera 330 can capture information outside the receiving groove 120 through the opening of the receiving groove 120.

[0047] For example, the camera module 300 can stop rotating at any position between the storage position and the shooting position. The camera module 300 can capture things at different angles at different positions. Thus, the camera module 300 can capture at least one of the environments above the front, in front of, and below the front of the learning machine 1. The content captured by the camera module 300 can be displayed on the display screen 200.

[0048] Installing the camera module 300 on the front surface 110 of the housing 100, compared with installing the camera module 300 on the back surface 150 of the housing 100, when the camera module 300 rotates from the storage position to the shooting position and is used to shoot forward or downward, the space required for the camera module 300 to rotate is smaller, the rotation trajectory of the camera module 300 is smaller, the learning machine 1 is more flexible to use, and when the learning machine 1 drops, the camera module 300 is more likely to be received into the receiving groove 120 to further prevent the camera module 300 from being damaged, achieving the technical effect of anti-falling.

[0049] Thus, the camera module 300 of the learning machine 1 according to the embodiment of the present application requires less space when rotating, has a low probability of damage, and can protect user privacy.

[0050] As Figures 1 - 4 shown, in some embodiments of the present application, when the camera module 300 is in the storage position, the camera module 300 does not protrude beyond the front surface 110; when the camera module 300 is in the shooting position, the camera 330 protrudes beyond the front surface 110.

[0051] In this way, when the camera module 300 is in the shooting position, the shooting angle of the camera 330 is larger, and objects closer to the learning machine 1 can be captured. When the camera 330 faces downward, it is easier to capture the content on the book, thereby improving the usability of the learning machine.

[0052] For example, when the learning machine drops, if the camera module 300 is in the storage position, the housing 100 can form a large-area enclosure around the camera module 300, reducing the probability of the camera module 300 being damaged by force; if the camera module 300 is in the shooting position, the housing 100 can also form an enclosure around the camera module 300, reducing the possibility of the camera module 300 being collided. Even if the camera module 300 is subjected to force, the camera module 300 can rotate from the shooting position to the storage position under the action of the external force, so that the camera module 300 is surrounded by the housing 100 in a large area, reducing the probability of the camera module 300 being damaged by force.

[0053] As Figures 1 - 4 shown, when the above-mentioned camera module 300 is in the storage position, the camera 330 faces the lower side wall of the receiving groove 120. When the camera module 300 is in the shooting position, the camera 330 faces downward the horizontal plane at the height where the camera 330 is located. For example, the camera 330 gradually slopes downward from inside the receiving groove 120 to outside the receiving groove 120. The horizontal plane at the height where the camera 330 is located refers to the plane parallel to the plane on which the learning machine 1 is placed and passing through the highest point of the camera 330. One end of the camera 330 facing away from the housing 100 is used to collect images, and the end of the camera 330 facing away from the housing 100 faces downward the horizontal plane at the height where the camera 330 is located.

[0054] In this way, the camera 330 can not only capture the reading material located below it, but also the camera module 300 has a small rotation angle, which can achieve the effect of micro-angle rotation, facilitating the camera module 300 to be received into the receiving groove 120 when the learning machine 1 drops, further preventing the camera module 300 from being damaged and achieving the technical effect of anti-fall.

[0055] In addition, since the shooting angle of the camera module 300 is downward, it is not easy to capture the user's facial information, which can improve the privacy protection ability.

[0056] The above-mentioned learning machine 1 can also have a controller, which is electrically connected to the camera module 300. The controller is used to control the camera module 300 to move to the storage position when receiving a detection signal sent by the camera module 300 indicating that there is no one in front of the learning machine 1.

[0057] For example, the controller can be installed inside the housing 100 of the learning machine 1, or the controller can be located between the learning machine 1 and the camera module 300 for wireless communication.

[0058] For example, when the camera module 300 is in the shooting position, if the image captured does not change within a preset time, that is, the reading material does not turn pages or move, and the learning machine 1 is not operated during this time period, it can be determined that the user is not present. Then the camera module 300 sends a no-person signal to the controller to control the camera module 300 to be in the storage position; alternatively, if the camera module 300 does not capture the outline of the user, such as the arm and body, within a preset time, it can be determined that the user is not present. Then the camera module 300 sends a no-person signal to the controller.

[0059] When the above camera module 300 switches between the storage position and the shooting position, the rotation angle is not greater than 90°. Among them, when the camera module 300 switches between the storage position and the shooting position, the rotation angle can be 90°, 80°, 70°, 60°, 50°, 40°, 30°, 20° or 10°, etc.

[0060] For example, when the camera module 300 is in the storage position, the camera 330 can face the lower side wall of the receiving groove 120. During the process of the camera module 300 rotating from the storage position to the shooting position, the camera 330 gradually moves forward. During the process of the camera module 300 moving from the storage position to the shooting position, the moving angle is not greater than 90°. In this way, the camera module 300 can already achieve shooting of the reading material below, and the camera module 300 can stop moving at any position within its rotation stroke, and the shooting range of the camera module 300 is larger.

[0061] Furthermore, when the above camera module 300 switches between the storage position and the shooting position, the rotation angle is not greater than 45°. Among them, when the camera module 300 switches between the storage position and the shooting position, the rotation angle can be 45°, 40°, 35°, 30°, 25°, 20°, 15°, 10° or 5°, etc.

[0062] In most cases, the distance between the reading material and the learning machine 1 is not too far. Therefore, controlling the rotation angle of the camera module 300 not to be greater than 45° can already achieve shooting of the content of the reading material within this rotation range. Moreover, since the rotation angle of the camera module 300 is small, the motor driving the camera module 300 is not easily blocked, the damage risk is small, and it is easy to control the rotation accuracy of the camera module 300. When the learning machine 1 drops, the camera module 300 is more likely to rotate towards the storage position.

[0063] Even further, when the above camera module 300 switches between the storage position and the shooting position, the rotation angle is not greater than 39°. Among them, when the camera module 300 switches between the storage position and the shooting position, the rotation angle can be 39°, 35°, 30°, 25°, 20°, 15°, 10° or 5°, etc.

[0064] In this way, it is ensured that the camera assembly 300 can capture the reading material in the vast majority of usage scenarios. Further, the maximum rotation angle of the camera assembly 300 is reduced, the motor driving the camera assembly 300 is not prone to jamming, the damage risk is small, and it is easy to control the rotation accuracy of the camera assembly 300. When the learning machine 1 drops, the camera assembly 300 is more likely to rotate towards the storage position.

[0065] Such as Figures 1 - 4 As shown, the above-mentioned receiving groove 120 is located above the display screen 200 and is spaced apart from the display screen 200. Specifically, when the learning machine 1 is in use, the receiving groove 120 is located above the display screen 200, the camera assembly 300 can be in the shooting position, and the camera assembly 300 can shoot forward and downward. The learning machine 1 can be used as a learning device. For example, the camera assembly 300 shoots forward and downward or scans the content on the book located below the learning machine 1 and displays the content on the display screen 200 for the user to learn.

[0066] In addition, the receiving groove 120 is spaced apart from the display screen 200. On the one hand, it can prevent the camera assembly 300 from interfering with the display screen 200 during rotation. On the other hand, at least a part of the display screen 200 is embedded in the housing 100, which can also prevent the edge of the display screen 200 from overlapping with the receiving groove 120, ensuring the connection reliability between the display screen 200 and the housing 100, and it is not easy for the display screen 200 to separate from the housing 100.

[0067] For example, the areas of the housing 100 on the left and right sides of the display screen 200 are smaller than the area of the housing 100 above the display screen 200 to increase the area of the display screen 200 and improve the space utilization rate of the housing 100.

[0068] Such as Figure 3 And Figure 4 As shown, the above-mentioned housing 100 has a first thickness area 130 and a second thickness area 140, and the thickness of the first thickness area 130 is greater than the thickness of the second thickness area 140. Among them, the receiving groove 120 is constructed in the first thickness area 130, and the display screen 200 is arranged in the second thickness area 140. Among them, when the learning machine 1 is in use, the first thickness area 130 can be located above the second thickness area 140.

[0069] By constructing the receiving groove 120 in the first thickness region 130, the first thickness region 130 has a greater thickness, which is conducive to increasing the depth of the receiving groove 120, providing a larger rotation space for the camera module 300. The size of the camera module 300 can be increased, which is beneficial to improving the shooting performance of the camera module 300, and more effectively accommodating the camera module 300, reducing the risk of the camera module 300 being damaged by collision in the storage position.

[0070] In addition, by disposing the display screen 200 in the second thickness region 140, the second thickness region 140 has a thinner thickness. The thickness of the second thickness region 140 can be greater than the thickness of the display screen 200, which can reduce the weight of the learning machine 1, reduce the volume of the learning machine 1, facilitate the miniaturization setting of the learning machine 1, and the material cost of the learning machine 1 can be reduced accordingly.

[0071] As Figure 3 and Figure 4 shown, the rear side of the above-mentioned first thickness region 130 protrudes backward from the rear side of the second thickness region 140. Among them, the front side of the second thickness region 140 does not protrude forward from the front side of the first thickness region 130. For example, the front side of the first thickness region 130, the front surface 110 of the display screen 200, and the front side of the region of the second thickness region 140 not blocked by the display screen 200 can be located on the same plane.

[0072] In this way, it can not only ensure that the thickness of the first thickness region 130 is greater than the thickness of the second thickness region 140, but also avoid the front side of the first thickness region 130 protruding forward excessively beyond the display screen 200, blocking the user's line of sight to view the display screen 200, and ensuring the experience of viewing the display screen 200.

[0073] As Figure 3 shown, there is a first distance D1 between the above-mentioned camera module 300 and the front side of the first thickness region 130, and there is a second distance D2 between the camera module 300 and the rear side of the first thickness region 130. Among them, the first distance D1 is less than the second distance D2.

[0074] For example, there is a side wall between the rear side of the first thickness region 130 and the camera module 300 in the receiving groove 120. By increasing the distance between the camera module 300 and the rear side of the first thickness region 130, it is convenient to form the above-mentioned side wall of the receiving groove 120, which is beneficial to blocking the rear side of the camera module 300, further reducing the exposed area of the camera module 300, and reducing the damage probability of the camera module 300.

[0075] In addition, the distance between the camera module 300 and the front side of the first thickness region 130 is reduced. When the camera module 300 is in the shooting position, the probability of the camera 330 being blocked by the groove wall of the receiving groove 120 is reduced, and the shooting range of the camera module 300 is larger.

[0076] As Figure 6 shown, the above camera assembly 300 includes a mounting shell 310, a bushing 320, a camera 330, and a patch cord 340.

[0077] The mounting shell 310 is rotatably disposed in the receiving groove 120. The mounting shell 310 is provided with a hollow rotating shaft 311 on one side in the extending direction of the rotation axis of the camera assembly 300. The bushing 320 is disposed on the housing 100. The relative position of the bushing 320 and the housing 100 is fixed. The hollow rotating shaft 311 rotatably passes through the bushing 320. The camera 330 is disposed in the mounting shell 310. The patch cord 340 is connected to the camera 330 and extends out of the mounting shell 310 from the hollow rotating shaft 311.

[0078] By providing the bushing 320, on the one hand, the mounting shell 310 can be rotated relative to the housing 100. On the other hand, it can prevent friction from occurring between the hollow rotating shaft 311 and the housing 100 due to contact, reduce the wear rate of the hollow rotating shaft 311 and the housing 100, and extend the service life of the mounting shell 310 and the housing 100.

[0079] Moreover, the camera 330 is mounted in the mounting shell 310. The mounting shell 310 can protect the camera 330, and by rotating the mounting shell 310 relative to the housing 100, the angle of the camera 330 relative to the housing 100 can be changed. The patch cord 340 is connected to the camera 330, and the camera 330 can transmit signals or be charged through the patch cord 340.

[0080] In addition, the patch cord 340 extends out of the mounting shell 310 from the hollow rotating shaft 311. Since the hollow rotating shaft 311 only rotates along its central axis when the mounting shell 310 rotates relative to the housing 100, the relative position between the patch cord 340 located in the hollow rotating shaft 311 and the housing 100 remains almost unchanged, avoiding situations such as the patch cord 340 being twisted, knotted, or broken, extending the service life of the patch cord 340, and the patch cord 340 is not likely to interfere with the housing 100, making the rotation of the camera assembly 300 smoother.

[0081] As Figure 6 , Figure 7 , Figure 10 and Figure 11As shown, a limiting post 312 is provided on the hollow rotating shaft 311, and a first limiting protrusion 321 and a second limiting protrusion 322 are provided on the inner peripheral surface of the shaft sleeve 320. The first limiting protrusion 321 and the second limiting protrusion 322 are arranged at intervals along the circumferential direction of the shaft sleeve 320, and the first limiting protrusion 321 and the second limiting protrusion 322 are located on opposite sides of the limiting post 312 in the circumferential direction of the hollow rotating shaft 311. Among them, when the camera assembly 300 rotates to the storage position, the limiting post 312 abuts against one of the first limiting protrusion 321 and the second limiting protrusion 322; when the camera assembly 300 rotates to the shooting position, the limiting post 312 abuts against the other of the first limiting protrusion 321 and the second limiting protrusion 322.

[0082] For example, the limiting post 312 is provided on the end face of one end of the hollow rotating shaft 311 facing the shaft sleeve 320, or the limiting post 312 is provided on the outer peripheral surface of the hollow rotating shaft 311. Through the cooperation between the first limiting protrusion 321, the second limiting protrusion 322 and the limiting post 312, the relative angle between the camera assembly 300 and the housing 100 can be limited, preventing the camera assembly 300 from rotating excessively and colliding with the housing 100, and it can be determined whether the camera assembly 300 rotates in place.

[0083] As Figure 5 shown, the above camera assembly 300 further includes a fixing bracket 350. The fixing bracket 350 is arranged in the mounting shell 310. The camera 330 includes a camera body 331 and a conductive clip 332. The camera body 331 and the conductive clip 332 are connected. The fixing bracket 350 is clamped between the camera body 331 and the conductive clip 332, and the patch cord 340 is connected to the side of the conductive clip 332 facing away from the fixing bracket 350.

[0084] For example, the camera body 331 and the conductive clip 332 can clamp the fixing bracket 350, and then the fixing bracket 350 is installed in the mounting shell 310. In this way, when the camera assembly 300 and the fixing bracket 350 are assembled, they are not restricted by the mounting shell 310, and the assembly of the camera assembly 300 and the fixing bracket 350 is more convenient.

[0085] The fixing bracket 350 and the mounting shell 310 can be connected by means of snap connection, threaded connection, bonding, interference fit, etc. Since it is not necessary to directly install the camera assembly 300 on the mounting shell 310, there is no need to modify the camera assembly 300, which is beneficial to ensuring the structural strength of the camera assembly 300, and the mounting shell 310 is not likely to interfere with the patch cord 340 and the conductive clip 332, facilitating the connection between the patch cord 340 and the conductive clip 332, and the patch cord 340 is electrically connected to the camera body 331 through the conductive clip 332.

[0086] As Figure 6 、Figure 7 and Figure 9 As shown in Figure 9 , the above-mentioned fixing bracket 350 includes a clamping portion 351, a first fixing portion 352 and a second fixing portion 353.

[0087] The inner wall of the mounting shell 310 is provided with a first support column 315 and a second support column 316. The first support column 315 and the second support column 316 are arranged at intervals along the extending direction of the rotation axis of the camera assembly 300. The clamping portion 351 is located between the first support column 315 and the second support column 316. The first fixing portion 352 is connected to the clamping portion 351 on one side of the extending direction of the rotation axis of the camera assembly 300. The side of the first support column 315 facing away from the camera body 331 is connected to the first fixing portion 352. The second fixing portion 353 is connected to the clamping portion 351 on the other side of the extending direction of the rotation axis of the camera assembly 300. The side of the second support column 316 facing away from the camera body 331 is connected to the second fixing portion 353.

[0088] By connecting the first fixing portion 352 to the first support column 315 and connecting the second fixing portion 353 to the second support column 316, a multi-point connection is formed between the fixing bracket 350 and the mounting shell 310. The connection between the fixing bracket 350 and the mounting shell 310 is more stable, with high connection strength, and it is not easy for relative rotation to occur between the fixing bracket 350 and the mounting shell 310.

[0089] For example, the first fixing portion 352 and the first support column 315 can be connected by a threaded fastener, and the second fixing portion 353 and the second support column 316 can be connected by a threaded fastener. Moreover, the fixing bracket 350 further includes a first connecting portion 355 and a second connecting portion 356. The first connecting portion 355 is respectively connected to the clamping portion 351 and the first fixing portion 352. The second connecting portion 356 is respectively connected to the clamping portion 351 and the second fixing portion 353. The first fixing portion 352 and the second fixing portion 353 are located in the same plane and are both arranged parallel to the clamping portion 351.

[0090] In addition, the clamping portion 351 protrudes towards the camera body 331 relative to the first fixing portion 352 and the second fixing portion 353, and the camera body 331 can be closer to the camera hole 314 described below, improving the shooting clarity of the camera head 330.

[0091] As Figure 9 shown, a groove 354 is provided on the side of the above-mentioned clamping portion 351 facing the camera body 331, and the camera body 331 is located in the groove 354. By placing the camera body 331 in the groove 354, the overall size of the camera assembly 300 and the fixing bracket 350 can be reduced, and pre-positioning can be achieved between the camera body 331 and the fixing bracket 350.

[0092] In addition, the camera body 331 and the clamping part 351 are adhesively bonded. For example, the camera body 331 and the clamping part 351 are connected by a foam adhesive to improve the connection strength between the camera body 331 and the clamping part 351, and it is not easy for the camera body 331 and the clamping part 351 to separate.

[0093] As Figure 6 and Figure 7 shown, the outer surface of the above-mentioned mounting shell 310 is provided with a positioning groove 313 and a camera hole 314. The camera hole 314 is respectively communicated with the positioning groove 313 and the inside of the mounting shell 310. A lens 400 is installed in the positioning groove 313, and the lens 400 blocks the camera hole 314. The camera 330 is located at the camera hole 314 and collects images through the lens 400.

[0094] For example, the lens 400 does not protrude beyond the outer surface of the mounting shell 310. On the one hand, it increases the contact area between the lens 400 and the mounting shell 310. On the other hand, it reduces the probability of the edge of the lens 400 being damaged during the rotation of the mounting shell 310.

[0095] By setting the positioning groove 313, the relative position between the lens 400 and the mounting shell 310 can be fixed. The lens 400 and the mounting shell 310 can be adhesively bonded or have an interference fit. The camera 330 takes pictures through the camera hole 314 and the lens 400. By setting the lens 400, it can not only prevent the camera 330 from being damaged, but also have little or no impact on the shooting of the camera 330.

[0096] In addition, the mounting shell 310 includes a first shell 317 and a second shell 318. The outer surface of the first shell 317 is provided with a positioning groove 313 and a camera hole 314. The second shell 318 is provided with a first support column 315 and a second support column 316. And a first threaded fastener 357 is inserted into the first shell 317 and connected to the first support column 315, and a second threaded fastener 358 is inserted into the second shell 318 and connected to the second support column 316. Among them, the first threaded fastener 357 and the second threaded fastener 358 are located in the positioning groove 313. In this way, the lens 400 can block the first threaded fastener 357 and the second threaded fastener 358, increasing the difficulty of disassembling and assembling the camera assembly 300, preventing the camera assembly 300 from being disassembled and assembled when it does not need to be repaired, and reducing the probability of damage to the camera assembly 300.

[0097] In addition, the learning machine 1 further includes an angle detection mechanism. The angle detection mechanism is installed on at least one of the housing 100 and the camera assembly 300, that is, the angle detection mechanism is installed on the housing 100, or the angle detection mechanism is installed on the camera assembly 300, or the angle detection mechanism is installed on both the housing 100 and the camera assembly 300. The angle detection mechanism is used for the rotation angle of the camera assembly 300.

[0098] For example, a first magnetic member 700 may be installed inside the installation housing 310. The first magnetic member 700 may be adhered to the second housing 318. A second magnetic member that cooperates with the first magnetic member 700 is provided inside the housing 100. When the camera module 300 rotates relative to the housing 100, the first magnetic member 700 is driven to move relative to the second magnetic member, so as to determine the rotation angle of the camera module 300.

[0099] The first magnetic member 700 and the second magnetic member cooperate to form Hall induction to detect the rotation angle of the camera module 300, so as to be able to determine whether the rotation of the camera module 300 is in place.

[0100] As Figure 8 shown, a first thinning groove 410 is provided on the side of the above-mentioned lens 400 facing the camera 330, and the camera 330 extends into the first thinning groove 410. In this way, on the one hand, it is convenient to position between the camera 330 and the lens 400, and the overall size between the camera 330 and the lens 400 is reduced, which is beneficial to the miniaturization of the camera module 300. On the other hand, by providing the first thinning groove 410, the thickness of the lens 400 at the position corresponding to the camera 330 can be reduced, the shooting influence of the lens 400 corresponding to the camera 330 is smaller, the shooting effect of the camera 330 is better, and the weight of the lens 400 is lighter and the cost is low.

[0101] As Figure 8 shown, a second thinning groove 420 is provided on the side of the above-mentioned lens 400 facing away from the camera, and the position of the camera 330 corresponds to that of the second thinning groove 420. Among them, in the plane parallel to the lens 400, the orthographic projection of the first thinning groove 410 is located inside the orthographic projection of the second thinning groove 420. For example, the area of the first thinning groove 410 is the same as that of the second thinning groove 420 and the positions correspond, or the area of the first thinning groove 410 is smaller than that of the second thinning groove 420. In this way, the thickness of the lens 400 at the position corresponding to the camera 330 can be further reduced, the shooting influence of the lens 400 corresponding to the camera 330 is smaller, the shooting effect of the camera 330 is better, and the weight of the lens 400 is lighter and the cost is low.

[0102] As Figure 6 shown, the above-mentioned learning machine 1 further includes a driving motor 500 and a reduction mechanism 600.

[0103] The driving motor 500 is arranged on the housing 100. The reduction mechanism 600 is respectively connected to the driving motor 500 and the installation housing 310. The driving motor 500 drives the camera module 300 to rotate between the storage position and the shooting position through the reduction mechanism 600. Among them, the reduction mechanism 600 and the hollow rotating shaft 311 are located on opposite sides of the installation housing 310 in the extending direction of the rotation axis of the camera module 300.

[0104] In this way, the driving force of the driving motor 500 can be transmitted to the mounting shell 310 through the speed reduction mechanism 600 to drive the mounting shell 310 to rotate relative to the housing 100. By setting the speed reduction mechanism 600, the function of speed reduction and torque increase can be achieved, making the rotation of the mounting shell 310 more stable.

[0105] For example, the mounting shell 310 is provided with a transmission rotating shaft. The transmission rotating shaft and the hollow rotating shaft 311 are located on opposite sides of the mounting shell 310 in the extending direction of the rotation axis of the camera assembly 300. The speed reduction mechanism 600 can be provided with a bushing, and the transmission rotating shaft is in transmission connection with the bushing.

[0106] The self-locking torque of the above-mentioned driving motor 500 is not greater than 10 N. The rotation speed of the driving motor 500 is not less than 2000 pps, the thrust is not less than 60 gf.cm, and the rated voltage is not less than 5 V to achieve the purpose that the self-locking torque of the driving motor 500 is not greater than 10 N.

[0107] In this way, the gravity of the learning machine 1 is much greater than the self-locking torque of the driving motor 500. When the learning machine 1 falls, the pressure received by the camera assembly 300 is greater than the self-locking torque of the driving motor 500, and the camera assembly 300 can easily move into the receiving groove 120. Moreover, when the learning machine 1 vibrates or moves, etc., the driving motor 500 can effectively lock the position of the camera assembly 300 to prevent the camera assembly 300 from shaking relative to the housing 100.
