[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in 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.

[0036] A learning machine is an electronic device used for educational and learning purposes. Users can acquire knowledge and educational resources through online learning, e-book reading, video watching, etc. The use of a learning machine can help people conduct activities such as remote learning, self-study, and online training, providing a more convenient and flexible way of learning.

[0037] However, when using a learning machine, an external bracket is usually required to support the learning machine for easy use by the user. If the user forgets to bring the bracket, the learning machine cannot be fixed at the desired display angle, which limits the flexibility of the learning machine. The external bracket requires additional space to carry, which increases the weight and burden on the user. In addition, the existing learning machines have limited application scenarios. For example, they are inconvenient to use in a car or without a table or chair.

[0038] See also Figure 1 to Figure 2 , an embodiment of the present application proposes a learning machine 10, including a device body 100, a first bracket 200 and a second bracket 500.

[0039] The first bracket 200 is rotatably connected to the device body 100, and can be rotated relative to the device body 100 to switch between an open state and a folded state. In the folded state, the first bracket 200 and the device body 100 are close to each other for folding. The second bracket 500 can be detachably connected to the device body 100 when the first bracket 200 is in the folded state, and is used to support the device body 100. In this way, the first bracket 200 can switch between an open state and a folded state relative to the device body 100, and the second bracket 500 can be detachably connected to the device body 100 when the first bracket 200 is in the folded state. In the open state, the first bracket 200 can cooperate with the device body 100, so as to support the learning machine 10 on the support surface. In this way, the user can easily place the learning machine 10 on a desktop or other support surface to better use the learning machine 10. In the folded state, the first bracket 200 is folded with the device body 100 and rests on the surface of the device body 100, so that the thickness of the first bracket 200 can be reduced, thereby facilitating the carrying and storage of the learning machine 10. In addition, when the first bracket 200 is in the folded state, the second bracket 500 is connected to the device body 100, so that the device body 100 can be fixed in different usage scenarios to meet different usage needs of users.

[0040] The device body 100 has a display surface, and the side of the device body 100 with the display surface is defined as the front side, and the side opposite to the display surface is defined as the back side, and the front side and the back side are arranged opposite to each other.

[0041] The first bracket 200 includes a support member 210 and a connecting member 220, and opposite sides of the connecting member 220 are rotatably connected to the device body 100 and the supporting member 210 respectively. The rotatable connection includes but is not limited to a hinge connection, a sleeve connection, a shaft connection, etc. Here, the present application does not limit the rotatable connection between the connecting member 220 and the device body 100, and between the connecting member 220 and the supporting member 210.

[0042] In some connection modes, the embodiment of the present application further includes a rotating shaft, the connecting member 220 is rotatably connected to the device body 100 through the rotating shaft, and the supporting member 210 is rotatably connected to the connecting member 220 through the rotating shaft. The connecting member 220 can rotate relative to the device body 100, and the supporting member 210 can rotate relative to the connecting member 220, so that the first bracket 200 can switch between an open state and a folded state relative to the device body 100. In the open state, the supporting member 210 and the device body 100 can both contact the supporting surface so that the learning machine 10 can be supported on the supporting surface. In the embodiment of the present application, the first bracket 200 is provided on the back of the learning machine 10, and the user can conveniently place the learning machine 10 on a desktop or other supporting surface to better use the learning machine 10. In the folded state, the supporting member 210 and the connecting member 220 are folded and abut against the surface of the device body 100, so that the thickness of the first bracket 200 can be reduced, thereby facilitating the carrying and storage of the learning machine 10.

[0043] The support member 210, the connector 220 and the rotating shaft may be made of metal, such as but not limited to aluminum alloy, stainless steel, copper, etc. The metal material has high strength and durability and can provide good support and connection functions. The support member 210, the connector 220 and the rotating shaft may be made of plastic, such as but not limited to PE (polyethylene), PP (polypropylene), PVC (polyvinyl chloride), PS (polystyrene), etc. The plastic material is light, low cost and good processability, which facilitates the processing of the support member 210, the connector 220 and the rotating shaft, and can also reduce the weight of the first bracket 200.

[0044] In some connection modes, one side of the connector 220 can be connected to the back of the device body 100, so as to facilitate use and facilitate the user to use the learning machine 10. In some other embodiments, one side of the connector 220 can also be connected to the side of the device body 100. As long as the connector 220 and the support member 210 can rotate relative to each other and cooperate with the device body 100 to support the learning machine 10 on the support surface, the present application does not limit the specific position of the rotational connection between the connector 220 and the learning machine 10.

[0045] To adjust the display angle of the display surface of the learning machine 10, please refer to Figure 3 , the rotation angle between the connecting member 220 and the device body 100, or the rotation angle between the connecting member 220 and the supporting member 210 of the embodiment of the present application can be adjusted, or the rotation angle between the connecting member 220 and the device body 100, and the rotation angle between the connecting member 220 and the supporting member 210 can be adjusted. Among them, Figure 3 a is a schematic diagram of the first bracket 200 in a folded state; Figure 3b is a schematic diagram of the first bracket 200 supporting the device body 100 at a first display angle; Figure 3 c is a schematic diagram of the first bracket 200 supporting the device body 100 at a first display angle; Figure 3 d is a schematic diagram showing that the first bracket 200 supports the device body 100 at a first display angle.

[0046] In order to facilitate the adjustment of the rotation angle between the connecting member 220 and the device body 100, and the rotation angle between the connecting member 220 and the supporting member 210, the rotating shaft (not shown in the figure) that is rotatably connected between the connecting member 220 and the device body 100, and the rotating shaft that is rotatably connected between the connecting member 220 and the supporting member 210 have a damping effect. In some structural forms, a gasket can be installed on the rotating shaft, and when the gaskets rotate, the gaskets are squeezed, thereby generating friction to provide a damping effect. Among them, those skilled in the art can adjust the magnitude of the friction by setting the number of gaskets and the tightness of the nut. When in use, the friction on the rotating shaft can make the display surface stay at the display angle desired by the user, so as to improve the user's experience. Of course, in some other embodiments, a liquid damper can also be set inside the rotating shaft to provide a damping effect through the viscosity and flow resistance of the liquid. When the rotating shaft rotates, the liquid in the liquid damper will be subjected to pressure or shear force, thereby generating flow resistance. This flow resistance will make the movement of the bracket have a damping effect through viscosity and friction, and the liquid damper can keep the display surface at the angle required by the user. Here, the application does not limit the specific form of forming the damping effect.

[0047] See also Figure 1 and Figure 2 , the support member 210 may be a disc-shaped structure, and in the folded state, the disc surface and the back surface of the support member 210 are close to each other. In some other embodiments, the support member 210 may also be a frame structure, a block structure, etc. The support member 210 may also be a circular structure, a rectangular structure or other irregular structure, as long as the learning machine 10 can be supported on the support surface. Here, the specific structure of the support member 210 is not limited in this application.

[0048] The connecting member 220 may be a flat block structure. In some other embodiments, the connecting member 220 may also be a rod structure, or a frame structure, etc. Here, the present application does not limit the specific form of the connecting member 220. Specifically, setting the connecting member 220 as a flat block structure can make the thickness of the connecting member 220 relatively small, thereby reducing the thickness of the learning machine 10 and making it easier to carry.

[0049] For further information, see Figure 4A receiving cavity 211 is formed on one side of the support member 210 connected to the connecting member 220. In the folded state, the connecting member 220 can be at least partially embedded in the receiving cavity 211. With such a configuration, when the first bracket 200 is folded at the back of the learning machine 10, the thickness of the first bracket 200 is relatively small, making it convenient for the learning machine 10 to be carried.

[0050] In order to charge the device body 100, please refer to Figure 2 , to facilitate the use of the learning machine 10, a charging interface 300 is provided on the device body 100. Through the charging interface 300, the device body 100 can be electrically connected to the power source and charged, so that the learning machine 10 does not need to replace the battery, which is convenient to use. In some embodiments, the charging interface 300 can use fast charging technology, which can charge the device faster and save the user's time. The charging interface 300 may include but is not limited to universal interfaces such as USB interface and type-C interface.

[0051] Furthermore, the charging interface 300 is arranged on the back of the device body 100, wherein, in the folded state, the first bracket 200 covers the charging interface 300. In this way, when not in use, the first bracket 200 can protect the charging interface 300, prevent dust, cotton wool and other impurities from entering the charging interface 300, and thus increase the reliability and service life of the charging interface 300. When charging is required, the first bracket 200 is opened and supports the learning machine 10, and then the charging cable is connected to the charging interface 300.

[0052] In order to facilitate the detachable connection between the device body 100 and the second bracket 500, please refer to Figure 5 The embodiment of the present application further includes an assembly portion 400 , which is disposed on the device body 100 and on the outer side of the first bracket 200 .

[0053] The second bracket 500 includes a matching portion 510 and a bracket main body 520. The bracket main body 520 is connected to the matching portion 510. The matching portion 510 can be detachably connected to the assembly portion 400 when the first bracket 200 is in a folded state, so that the bracket main body 520 can support the learning machine 10. In this way, by connecting the assembly portion 400 with different second brackets 500, the device body 100 can be fixed in different usage scenarios to meet different usage requirements. For example, the second bracket 500 can be a floor bracket. In this way, when there is no study table or table stool available, the second bracket 500 can support the device body 100, so that the display surface of the device body 100 can have the user's desired usage angle; the second bracket 500 can also be a vehicle-mounted bracket, which is fixed to the headrest bracket of the car seat through the vehicle-mounted bracket, so as to meet the scenario of the rear-seat users using the learning machine 10 in the mobile scene of the car.

[0054] In some structural forms, the assembly part 400 can be a magnet of an annular structure, and surround the outer side of the first bracket 200, and the matching part 510 is magnetically attracted to the assembly part 400. It is understandable that the magnet of the annular structure can be an integral structure or a split structure. Specifically, the annular magnet of the integral structure can be conveniently installed on the device body 100, and when it is a magnet of a split structure, the magnet can be set to multiple, and the multiple magnets can be arranged in a circle on the device body 100. Since the magnet has a strong adsorption force, it is only necessary to align the assembly part 400 with the matching part 510 on the second bracket 500 to complete the fixation. This method is faster and more convenient than other fixing methods. At the same time, since the magnet has a simple structure and a small size, a more stable fixing effect can be achieved without affecting the overall weight and appearance of the device, thereby improving the user experience of the device. Of course, in some other structural forms, the assembly part 400 can also be a card hole set on the device body 100, and the matching part 510 can be a buckle. The buckle can be inserted into the card hole to match and fix the assembly part 400 and the matching part 510. Here, this application does not limit the specific matching and fixing method between the assembly part 400 and the matching part 510.

[0055] Furthermore, a side of the mating portion 510 facing the first bracket 200 is provided with an avoidance groove (not shown in the figure), and the avoidance groove is used to accommodate at least part of the structure of the first bracket 200 after the mating portion 510 is connected to the assembly portion 400. In this way, the structure of the first bracket 200 can be better accommodated in the second bracket 500, thereby more stably supporting the learning machine 10. The avoidance groove can avoid interference and conflict between the first bracket 200 and the mating portion 510, and reduce unnecessary friction and damage. In this way, when using the learning machine 10, the user can place it on the second bracket 500 with greater peace of mind, without worrying about the device accidentally falling or being unstable, thereby improving the convenience and safety of use.

[0056] In some structural forms, see Figure 5 and Figure 6 The bracket main body 520 may include a vertical rod 521 and a base 522. The vertical rod 521 is connected to the matching portion 510, and the base 522 is connected to the vertical rod 521. The device body 100 can be fixed on different support surfaces through the base 522 and the vertical rod 521, and the device body 100 can be supported to a certain height, so that the display angle of the display surface can be raised to meet different user requirements. It can be understood that the vertical rod 521 can be retractable, and the height of the device body 100 can be adjusted by adjusting the length of the vertical rod 521, thereby meeting different display requirements of users.

[0057] For further information, see Figure 7, the mating portion 510 can rotate relative to the vertical rod 521, so that the assembly portion 400 that is magnetically attracted to the mating portion 510 can rotate relative to the vertical rod 521, thereby adjusting the display angle of the learning machine 10. The vertical rod 521 can also rotate relative to the base 522, so that the display angle of the learning machine 10 can also be adjusted. It can be understood that the mating portion 510 and the vertical rod 521 can be rotatably connected, and the vertical rod 521 and the base 522 can be rotatably connected. It can also be set in combination, and this application does not limit this. Among them, Figure 7 a is a schematic diagram showing that the second bracket 500 supports the device body 100 at a first display angle; Figure 7 b is a schematic diagram of the second bracket 500 supporting the device body 100 at a second display angle; Figure 7 c is a schematic diagram of the second bracket 500 supporting the device body 100 at a third display angle.

[0058] Of course, in some other embodiments, the matching portion 510 and the vertical rod 521 can be fixedly connected, such as but not limited to welding, screwing, clamping, etc. The vertical rod 521 and the base 522 can also be fixedly connected, such as but not limited to welding, screwing, clamping, etc.

[0059] In order to facilitate the use of the learning machine 10, a roller (not shown) may be provided at the bottom of the base 522. By sliding the roller, the learning machine 10 can be moved to different usage scenarios. In some structural forms, the roller may be provided with a brake device, so that after the learning machine 10 is moved into place, the brake device is locked to fix the learning machine 10 in the desired position.

[0060] In some structural forms, see Figure 8 , the bracket body 520 includes a fixing clip 523 connected to the matching portion 510, and the fixing clip 523 is used to clamp or clamp the external structure. The fixing clip 523 may include two oppositely arranged buckle portions 5231, and a card slot 5232 is formed between the two buckle portions 5231, wherein the opening size of the card slot 5232 gradually decreases in the direction away from the matching portion 510, and the two buckle portions 5231 can be close to or away from each other. In some embodiments, the fixing clip 523 can be made of plastic material, such as but not limited to PE (polyethylene), PP (polypropylene), PVC (polyvinyl chloride), PS (polystyrene), etc., so that the two buckle portions 5231 have a certain elastic deformation ability, so that they can be close to or away from each other. In this way, the headrest bracket of the vehicle seat can be clamped by the fixing clip 523, so that users sitting in the back row of the vehicle can use the learning machine 10.

[0061] In some connection modes, the mating portion 510 and the fixing clip 523 can be rotatably connected, so that the angle of the display surface of the device body 100 can be adjusted. Fig. 9 and Fig.10 , by adjusting the angle between the matching portion 510 and the fixing clip 523, it is convenient for the user to use the learning machine 10. In some other embodiments, the matching portion 510 and the fixing clip 523 can also be fixedly connected, such as but not limited to welding, screwing, clamping, etc. In some other embodiments, the fixing clip 523 can be a spring clip, and a spring mechanism is provided between the two clamping jaws. The spring mechanism can keep the two clamping jaws in a closed state, and clamp or release the object by loosening or pressing a button. Here, the present application does not limit the specific form of the fixing clip 523.

[0062] In order to improve the versatility of the learning machine 10, the learning machine 10 of the embodiment of the present application also includes a camera 600. In some structural forms, the camera 600 is arranged on the top of the learning machine 10. The camera 600 can be used for video conferencing and remote learning. Users can conduct real-time audio-visual communication with others through the camera 600, whether participating in online meetings or remote learning courses, which can be carried out more conveniently and intuitively. This enables users to communicate and learn in different locations, breaking the limitations of time and space. The camera 600 enables the learning machine 10 to easily record teaching videos or demonstration tutorials. Educators or students can use the camera 600 to record their explanations, experimental processes or other teaching content for subsequent viewing or sharing with others. This provides more possibilities and flexibility for teaching and learning. In addition, the camera 600 can also perform face recognition and identity authentication to enhance the security of the learning machine 10. Users can use the facial recognition function to log in to ensure that only authorized personnel can use the device. This can prevent unauthorized access and use and protect the privacy and data security of users.
