[0031] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0032] In order to simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0033] With the development of smart education, tool-type educational hardware represented by learning machines and learning tablets have entered the public eye. They are deeply loved by users for their large screens, multiple functions and advantages that are conducive to learning. However, due to the functional requirements of learning machines, they require powerful processor support, resulting in a relatively high cost. The general price is in the range of 1,000-4,000 yuan, which is not conducive to popularization.

[0034] Smart watches, phone watches, smart bracelets and other wearable smart devices are widely used among children and students. They have one or more functions such as calling, positioning, reminders, navigation, calibration, monitoring, interaction, etc., and can be connected to the Internet through smart phones or home networks, and can download and use application software through Apple or Android systems. Therefore, they usually have a more powerful processor. Since smart watches are related to the safety of children and students, they are more important to children and students than learning machines and learning tablets; and the existing smart education usually requires children and students to buy both products; if the functions of learning machines, learning tablets and other devices are realized by using the processors of wearable smart devices such as smart watches, there is no need to purchase additional learning machines, learning tablets and other devices. Only one smart watch is needed to realize all functions, which is conducive to reducing learning costs.

[0035] In one embodiment, the reference specification Figures 1 to 3 The present invention provides an expansion device based on a wearable intelligent device 4, comprising: a mounting seat 1 and an expansion screen 2, wherein the expansion screen 2 is arranged on the mounting seat 1. The mounting seat 1 can be a three-dimensional type, such as a rectangular parallelepiped, a cylindrical type, etc., and the expansion screen 2 is arranged on a side of the mounting seat 1; the mounting seat 1 can also be a bracket type, and the expansion screen 2 is arranged on the bracket of the mounting seat 1. The purpose of the mounting seat 1 is to fix and support the expansion screen 2, and its specific form is not limited. The expansion screen 2 can be an LCD screen, a touch screen, etc., and its size is adjusted according to the use requirements, which is not limited here.

[0036] When connecting the mounting base 1 and the extended screen 2, a fixed connection or an active connection can be adopted, such as the extended screen 2 can be rotated or flipped around the mounting base 1; and the extended screen 2 can be electrically connected to the control structure that controls the display content of the extended screen 2 through the lines, holes, etc. arranged on the mounting base 1.

[0037] Buttons, operation keys and other structures may also be provided on the mounting base 1, and electrically connected to the extended screen 2 or a control structure that controls the display content of the extended screen 2 to achieve manual control or operation.

[0038] The extended screen 2 can be a whole display screen, or multiple display screens can be used in combination. For example, in one example, the extended screen 2 is composed of four display screens. The four display screens can be combined into a whole to display content, or they can be moved along the mounting base 1 and distributed on the four sides of the mounting base 1 to achieve simultaneous display in all directions, making the application scenarios of the device more extensive.

[0039] The mounting seat 1 is provided with a placement cavity 3 adapted to the wearable smart device 4, and the placement cavity 3 is used to place the wearable smart device 4. In this embodiment, the wearable smart device 4 is fixed by providing the placement cavity 3 on the mounting seat 1, so that the installation of the wearable smart device 4 is more stable. In other embodiments, other fixing forms may also be used, such as providing a clamping member, a connecting member, etc. adapted to the wearable smart device 4 on the mounting seat 1, which is not limited here.

[0040] The placement cavity 3 can be set on the side, bottom, top, etc. of the mounting seat 1, and its size is comparable to the size of a wearable smart device 4 such as a smart device; an elastic structure can be additionally set in the placement cavity 3, which, on the one hand, makes the wearable smart device 4 more firmly fixed and will not damage the wearable smart device 4, and on the other hand, enables the placement cavity 3 to adapt to wearable smart devices 4 of different models or types.

[0041] The placement cavity 3 is connected to the wearable smart device 4 by sliding, snap-on, or the like. When the wearable smart device 4 needs to be used as a learning machine or a learning tablet through the extended screen 2, the wearable smart device 4 only needs to be placed in the placement cavity 3. A first connector that can be electrically connected to the processor of the wearable smart device 4 is provided in the placement cavity 3; the first connector is a PIN pin, a PIN hole, etc., and the extended screen 2 is electrically connected to the first connector. The wearable smart device 4 is provided with a connection structure that is compatible with the first connector, so that when the wearable smart device 4 is placed in the placement cavity 3, the extended screen 2 can be electrically connected to the processor of the wearable smart device 4, so that the expansion device can utilize the powerful processor of the existing wearable smart device 4 such as a smart watch, and realize the expansion of the function of the wearable smart device 4 through the extended screen 2, so as to meet the same requirements as those of devices such as learning machines and learning tablets, and reduce costs.

[0042] The processor in the embodiment of the present application may be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor, an algorithm chip, or any conventional processor, etc.

[0043] In addition, since the processor functions of the existing smart devices such as wearable smart devices 4 are powerful enough, and the main purpose of the learning machine, learning tablet and other devices is to assist children and students in learning, no other additional functions are required. Therefore, the processor of the wearable smart device 4 is sufficient for use, and there is no need to further improve the function of the processor of the wearable smart device 4, and it can be used directly, which is also one of the reasons why this application is convenient to apply and promote.

[0044] Specifically, when in use, according to the learning function that the user needs to use, the corresponding software is downloaded through the wearable smart device 4 such as a smart watch. After downloading and installation, the wearable smart device can be placed in the placement cavity 3. Since the processor of the wearable smart device 4 is electrically connected to the expansion screen 2, the corresponding content can be displayed through the expansion screen 2. The expansion screen 2 or the mounting seat 1 is provided with buttons, speakers and other structures, and corresponding operations can be performed through these structures to achieve the same purpose as using a learning machine or a learning tablet.

[0045] In one embodiment, the reference specification Figures 1 to 3 On the basis of the foregoing embodiment, the mounting base 1 includes a mounting bracket 11, the extended screen 2 is mounted on one side of the mounting bracket 11, and the extended screen 2 is electrically connected to the first connecting member through a line channel provided in the mounting bracket 11.

[0046] In this embodiment, the mounting base 1 adopts a bracket-type structure, and the mounting bracket 11 is a columnar structure, and its material can be metal, plastic, etc. The extended screen 2 is installed on the top side of the mounting bracket 11, and the extended screen 2 can be fixedly connected or movably connected; a wire groove is provided at the connection between the extended screen 2 and the mounting bracket 11, and a line channel is provided inside the mounting bracket 11, so that the extended screen 2 can be electrically connected to the first connecting member by a hard connection, thereby realizing the corresponding display function of the extended screen 2.

[0047] Preferably, the placement cavity 3 is arranged on the other side of the mounting bracket 11 relative to the extended screen 2 .

[0048] By setting the placement cavity 3 on the other side of the mounting bracket 11 relative to the extended screen 2, when the extended screen 2 is in use, the wearable smart device 4 can be located on the back of the mounting base 1, making the device more beautiful; when the extended screen 2 is not needed, or only the voice function, alarm function, story listening and other functions are performed through the extension device, the extended screen 2 can be rotated to face the back, making the use of the device more user-friendly.

[0049] Further preferably, the mounting base 1 also includes a base 12 , and the mounting bracket 11 is movably connected to the base 12 .

[0050] The base 12 is a machine for the mounting base 1. When in use, the base 12 can be placed on a desktop. By providing a mounting bracket 11 movably connected to the base 12, the expansion device can be rotated when in use, thereby rotating the expansion screen 2 to face the back, or rotating the placement cavity 3 to face the back.

[0051] Preferably, the mounting bracket 11 can rotate 360° around the base 12 .

[0052] Specifically, a rotation hole is provided on the top surface of the base 12, the bottom of the mounting bracket 11 is circular and can be stuck in the rotation hole, and the bottom of the mounting bracket 11 is connected to the rotation hole through a bearing, so that the mounting bracket 11 can rotate around the base 12. A limit ring can be provided on the top surface of the rotation hole to prevent the mounting bracket 11 from detaching from the base 12; a torsion spring or a buckle assembly can also be provided in the rotation hole, so that the mounting bracket 11 can be fixed after rotating to a preset angle, and can rotate again after an external force is applied.

[0053] Preferably, a sound outlet 13 is provided on the other side of the mounting bracket 11 relative to the extended screen 2 .

[0054] A speaker assembly is provided in the sound outlet 13, and the speaker assembly is electrically connected to the extension screen 2 or the first connecting member, so that when the extension device is in use, it can play sound through the sound outlet 13, thereby realizing the extended functions of some software, such as storytelling function, alarm clock function, etc.

[0055] In the present application, the function of the first connector is to electrically connect to the processor of the wearable smart device 4 when the wearable smart device 4 is placed in the placement cavity 3. The specific form of the first connector can be various.

[0056] In one embodiment, the first connector is a first PIN pin disposed on the inner wall of the placement cavity 3. A first PIN pin hole corresponding to the first PIN pin is disposed on the wearable smart device 4. The PIN pin is a metal material used in the connector to complete the conduction (transmission) of electricity (signals). The PIN pin material is made of "tungsten carbide" raw material, that is, cemented carbide, which has high hardness, strength, wear resistance and corrosion resistance.

[0057] In this embodiment, the PIN needle can not only be used for signal transmission, but also can be used to charge the wearable smart device 4 placed in the placement cavity 3. Since users, especially children, students and other users, often forget to charge the wearable smart device 4 when using the wearable smart device 4, which affects the normal use of the wearable smart device 4, the present application can also charge the wearable smart device 4 while utilizing the powerful processor of the existing wearable smart device 4 for function expansion, making the device more powerful and more convenient and user-friendly to use.

[0058] There are also many ways to place the wearable smart device 4 in the placement cavity 3. In one example, the two sides of the placement cavity 3 can be provided with two side end surfaces that penetrate the mounting bracket 11, so that the wearable smart device 4 can slide into or out of the placement cavity 3 through the side of the mounting bracket 11. For example, when the wearable smart device 4 is a smart watch, when using it, it is only necessary to hold the watch body or the watch strap and slide the smart watch into the placement cavity from the side of the mounting bracket 11; when taking it out, it is only necessary to continue sliding the smart watch to take it out.

[0059] The first PIN pin can be set on the side wall of the placement cavity 3. The first PIN pin is an elastic PIN pin, so that when the wearable smart device 4 slides in or out along the side of the mounting bracket 11, the first PIN pin can be retracted into the inside of the placement cavity 3, thereby not affecting the sliding of the wearable smart device 4; the first PIN pin can also be set to be able to extend or retract from the side wall of the placement cavity 3 manually and actively.

[0060] The first PIN needle can also be movably installed on the side wall of the placement cavity 3 through a movable part, so that when the wearable smart device 4 slides in or out along the side of the mounting bracket 11, the first PIN needle can be rotated to fit the side wall of the placement cavity 3, thereby not affecting the sliding of the wearable smart device 4.

[0061] By setting the first PIN needle as an elastic PIN needle or setting the first PIN needle to be movably installed on the side wall of the placement cavity 3 through a movable part, when the wearable smart device 4 slides to the preset position of the placement cavity 3 (that is, the position where the first PIN needle can be inserted into the first PIN needle hole), the first PIN needle can be electrically connected to the first PIN needle hole preset on the wearable smart device 4. Since the first PIN needle hole is electrically connected to the processor of the wearable smart device 4, the first PIN needle can be electrically connected to the processor of the wearable smart device 4, thereby realizing the electrical connection between the extended screen 2 and the processor of the wearable smart device 4.

[0062] In one example, the inner wall of the placement cavity 3 may also be provided with an elastic member, such as a rubber ring or a silicone ring is provided around the inner wall of the placement cavity 3, and the top surface of the rubber ring or the silicone ring is provided with a guide surface, so that the wearable smart device 4 can be directly inserted into or pulled out of the placement cavity 3; in this example, the first PIN needle is directly provided at the bottom of the placement cavity 3, so that when the wearable smart device 4 is inserted into the placement cavity 3, the first PIN needle can be electrically connected to the second PIN pin hole preset on the bottom surface of the wearable smart device 4. Since the second PIN pin hole is electrically connected to the processor of the wearable smart device 4, the first PIN needle can be electrically connected to the processor of the wearable smart device 4, thereby realizing the electrical connection between the extended screen 2 and the processor of the wearable smart device 4.

[0063] In one embodiment, the first connector is a third PIN pinhole provided on the inner wall of the placement cavity 3, and a second PIN pin corresponding to the third PIN pinhole is provided on the wearable smart device 4. When the wearable smart device 4 is placed in the placement cavity 3, the third PIN pinhole can be electrically connected to the second PIN pin on the wearable smart device 4, and since the second PIN pin is electrically connected to the processor of the wearable smart device 4, the third PIN pinhole can be electrically connected to the processor of the wearable smart device 4, thereby realizing the electrical connection between the extended screen 2 and the processor of the wearable smart device 4.

[0064] When the first connecting member is a third PIN pinhole arranged on the inner wall of the placement cavity 3, there are also multiple ways to place the wearable smart device 4 in the placement cavity 3. In one example, the two sides of the placement cavity 3 are arranged to pass through the two side end surfaces of the mounting bracket 11, so that the wearable smart device 4 can slide into or out of the placement cavity 3 through the side of the mounting bracket 11.

[0065] The third PIN pin hole can be set on the side wall of the placement cavity 3, and the second PIN pin preset on the wearable smart device 4 is an elastic PIN pin, so that when the wearable smart device 4 slides in or out along the side of the mounting bracket 11, the second PIN pin can be retracted to the inside of the wearable smart device 4, thereby not affecting the sliding of the wearable smart device 4, and the second PIN pin can also be set to be able to be manually actively extended or retracted from the wearable smart device 4; the second PIN pin can also be movably installed on the wearable smart device 4 through a movable part, so that when the wearable smart device 4 slides in or out along the side of the mounting bracket 11, the second PIN pin can be rotated to fit the side wall of the wearable smart device 4, thereby not affecting the sliding of the wearable smart device 4.

[0066] By setting the second PIN needle of the wearable smart device 4 as an elastic PIN needle or setting the second PIN needle to be movably installed on the wearable smart device 4 through a movable part, when the wearable smart device 4 slides to the preset position of the placement cavity 3 (that is, the position where the second PIN needle can be inserted into the third PIN needle hole), the third PIN needle hole can be electrically connected to the second PIN needle preset on the wearable smart device 4. Since the second PIN needle is electrically connected to the processor of the wearable smart device 4, the third PIN needle hole can be electrically connected to the processor of the wearable smart device 4, thereby realizing the electrical connection between the extended screen 2 and the processor of the wearable smart device 4.

[0067] In one example, the inner wall of the placement cavity 3 may also be provided with an elastic member, such as a rubber ring or a silicone ring is provided around the inner wall of the placement cavity 3, and the top surface of the rubber ring or the silicone ring is provided with a guide surface, so that the wearable smart device 4 can be directly inserted into or pulled out of the placement cavity 3; in this example, the third PIN pinhole can be directly provided on the bottom or side wall of the placement cavity 3, so that when the wearable smart device 4 is inserted into the placement cavity 3, the third PIN pinhole can be electrically connected to the second PIN pin preset on the bottom or side of the wearable smart device 4. Since the second PIN pin is electrically connected to the processor of the wearable smart device 4, the third PIN pinhole can be electrically connected to the processor of the wearable smart device 4, thereby realizing the electrical connection between the extended screen 2 and the processor of the wearable smart device 4.

[0068] Preferably, the first connector is a charging connector, and the mounting base 1 is connected to an external power source so that the wearable smart device 4 can be charged when the wearable smart device 4 is placed in the placement cavity 3.

[0069] In one embodiment, the reference specification Figures 1 to 3 The present invention also provides a display system, including a wearable intelligent device 4, and an expansion device based on the wearable intelligent device 4.

In addition, since the processor function of the wearable smart device 4 such as the existing smart device is already powerful enough, and the main purpose of the learning machine, learning tablet and other devices is to assist children and students in learning, no other additional functions are required. Therefore, the processor of the wearable smart device 4 is sufficient for use, and there is no need to further improve the function of the processor of the wearable smart device 4, and it can be used directly.

[0071] Specifically, when in use, according to the learning function that the user needs to use, the corresponding software is downloaded through the wearable smart device 4 such as a smart watch. After downloading and installation, the wearable smart device can be placed in the placement cavity 3. Since the processor of the wearable smart device 4 is electrically connected to the expansion screen 2, the corresponding content can be displayed through the expansion screen 2. The expansion screen 2 or the mounting seat 1 is provided with buttons, speakers and other structures, and corresponding operations can be performed through these structures to achieve the same purpose as using a learning machine or a learning tablet.
