The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "vertical", "horizontal", etc. used in this specification is based on the orientation or positional relationship shown in the accompanying drawings, only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0040] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0041] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] As written records become more popular and complex, handwriting has gradually become inefficient and prone to errors. Especially after the Industrial Revolution, with the surge in information processing, people need a tool that can quickly and accurately input text to support daily work and study. Therefore, the keyboard, as an input device that converts human finger movements into electronic or mechanical signals, came into being, greatly improving the efficiency of information processing.

[0043] Keyboards are used in all walks of life. For example, in the teaching industry, keyboards provide an efficient way of interaction for online education platforms. Students can use the keyboard to enter answers, complete homework, participate in online discussions, etc. In the online examination system, students can use the keyboard to quickly and accurately enter text answers, which greatly improves the efficiency of answering questions compared to handwriting input. For example, in programming teaching, the keyboard is a key tool for students to communicate with computers. By entering code instructions on the keyboard, students can practice programming ideas and cultivate logical thinking and problem-solving skills. In multimedia teaching, the keyboard can facilitate teachers to make and demonstrate courseware. Teachers can use the keyboard to enter text, edit picture annotations, etc., making the teaching content richer and more vivid. It can be seen that keyboards have played an indispensable role in people's lives.

[0044] During the teaching process, students are unable to switch the computer display to view relevant information due to software interface limitations or management permission restrictions. They have to use mobile devices such as mobile phones or tablets to view information while operating the computer based on the information on the mobile devices. However, if the mobile devices are placed on the desktop, it is difficult to view the information at a suitable angle, which is not conducive to students operating the keyboard.

[0045] The inventor of this application has found through research that the keyboard structure design on the market is relatively simple and the function is relatively single, and it is impossible to place mobile devices such as mobile phones or tablets, thus failing to meet the teaching needs of students. To this end, the inventor of this application has set a structure on the keyboard to constrain mobile devices such as mobile phones or tablets so that the mobile devices can be placed on the keyboard. The specific solution is as follows:

[0046] like Figure 1-2 As shown, a keyboard 1 provided in one embodiment of the present application includes a base 2, a middle frame module 3 and a key module 4, wherein the middle frame module 3 is connected to the base 2, and the key module 4 is connected to the middle frame module 3. The middle frame module 3 includes a middle frame plate 31 and a supporting protrusion 32 connected to each other, wherein the middle frame plate 31 is connected to the base 2, the supporting protrusion 32 is protruded relative to the surface of the middle frame plate 31 in a direction away from the base 2, and the supporting protrusion 32 and the key module 4 are located on the same side of the middle frame plate 31. There is a preset spacing between the key module 4 and the supporting protrusion 32, and a receiving groove 101 is constructed between the middle frame plate 31, the supporting protrusion 32 and the key module 4, and a limiting protrusion 401 is provided on the side of the key module 4 facing the supporting protrusion 32, and the limiting protrusion 401 is used to resist the mobile device located in the receiving groove 101.

[0047] Through the above structure, the back of the mobile device can lean against the support protrusion 32, such as Figure 3As shown, the side edges of the mobile device respectively abut the middle frame plate 31 and the limiting protrusion 401, so that the mobile device is constrained and will not fall directly relative to the base 2, which is convenient for the user to view the mobile device while operating the keyboard 1, thereby increasing the usage scenarios and functions of the keyboard 1 and improving the user experience.

[0048] In some embodiments, Figure 4 As shown, a support structure 21 is provided in the base 2, and the support structure 21 abuts against the middle frame plate 31 to support the middle frame plate 31. The support structure 21 can be a support column 211, or a reinforcing rib 212, or a combination of the support column 211 and the reinforcing rib 212, or other structures as long as they can play a supporting role. In this embodiment, the support structure 21 adopts a combination structure of the support column 211 and the reinforcing rib 212, so that it can not only play a role in enhancing the strength of the base 2, but also play a role in supporting other components.

[0049] In some embodiments, please refer again to Figure 2 or Figure 3 A plurality of support bars 22 are provided on one end surface of the base 2 away from the middle frame plate 31. The plurality of support bars 22 are arranged at intervals and are used to support and raise the base 2. When the keyboard 1 is placed on a support surface such as a desktop, the plurality of support bars 22 are helpful to reduce the contact area between the base 2 and the support surface, thereby reducing the risk of the base 2 being contaminated by the support surface.

[0050] In some embodiments, Figure 1-2 As shown, the receiving slot 101 is in the length direction of the keyboard 1 (such as Figure 1 In other words, there is no shielding at both ends of the receiving slot 101 in the length direction of the keyboard 1, which facilitates the user to clean the dust, dander or other pollutants dropped into the receiving slot 101.

[0051] It should be understood that the inclination direction and inclination angle of the support protrusion 32 relative to the surface of the middle frame plate 31 can be set as needed, as long as the mobile device can be supported. For example, the support protrusion 32 extends along the side close to the key module 4 relative to the middle frame plate 31, or the support protrusion 32 extends along the side away from the key module 4 relative to the middle frame plate 31. In this embodiment, Figure 2As shown, the support protrusion 32 is inclined relative to the surface of the middle frame plate 31 and extends along the side close to the key module 4, and the inclination angle of the support protrusion 32 relative to the surface of the middle frame plate 31 is α, satisfying α<90°. In this way, when the support protrusion 32 supports the mobile device, the light emitted by the mobile device can be more directed to the user, which is beneficial for the user to view the mobile device. Further, the inclination angle α of the support protrusion 32 relative to the surface of the middle frame plate 31 satisfies 60°≤α<90°, so that the angle at which the support protrusion 32 supports the mobile device is appropriate, which helps the light emitted by the mobile device to be more directed to the user, and reduces the risk of external light shining on the mobile device and causing reflection. Specifically, α can be 60°, 70°, 75°, 80° or 85°.

[0052] In some embodiments, Figure 2 As shown, a curved guide surface 301 is provided on one side of the support protrusion 32 close to the button module 4. The curved guide surface 301 is used to guide the mobile device to be accommodated in the accommodating groove 101. The curved guide surface 301 is configured to be recessed in a direction away from the button module 4. This is beneficial for the user to place the mobile device in the accommodating groove 101. Under the action of the curved guide surface 301, the mobile device will slide to an appropriate position in the accommodating groove 101, making it convenient for the user to place the mobile device.

[0053] In some embodiments, Figure 4 As shown, the middle frame plate 31 is provided with a receiving space 302 , and the receiving space 302 is used to receive part of the key module 4 , so that the supporting structure 21 in the base 2 can support part of the key module 4 .

[0054] In some embodiments, Figure 2 , Figure 4 and Figure 5 As shown, the button module 4 includes a button shell 41, which is connected to the middle frame plate 31 and is located on the side of the middle frame plate 31 away from the base 2. The button shell 41 includes a first side end 411 and a second side end 412 that are oppositely arranged. The first side end 411 is closer to the support protrusion 32 than the second side end 412, and the first side end 411 is provided with a limiting protrusion 401. Figure 2 The thickness of the first side end 411 is greater than the thickness of the second side end 412, so that a surface of the key shell 41 away from the middle frame plate 31 is tilted relative to the middle frame plate 31. In this embodiment, a surface of the key shell 41 away from the middle frame plate 31 is a bearing surface 413, and the bearing surface 413 connects the first side end 411 and the second side end 412. When a key for tapping is installed on the bearing surface 413, since the bearing surface 413 is tilted relative to the middle frame plate 31, the key is also tilted relative to the middle frame plate 31, which is conducive to user pressing and improves user experience.

[0055] In some embodiments, Figure 4 and Figure 5 As shown, the key module 4 further includes a plurality of key caps 42, a flexible circuit board group 43 and a soft plastic part 44. The key shell 41 is provided with a plurality of key holes 414, one key cap 42 is provided in one key hole 414, the soft plastic part 44 is provided on one end surface of the flexible circuit board and is located below the key cap 42, and the other end surface of the flexible circuit board group 43 can abut against the base 2. In this embodiment, as shown in FIG. Figure 5 As shown, the flexible circuit board group 43 includes a first flexible circuit board 431, a second flexible circuit board 432 and an insulating film (not shown in the figure), the insulating film is arranged between the first flexible circuit board 431 and the second flexible circuit board 432, and the insulating film is kept away from air in the area where each key cap 42 is pressed, so that when the user presses the key cap 42, the soft rubber part 44 can press the second flexible circuit board 432, thereby triggering a signal of pressing the key at that location.

[0056] The button shell 41 and the limiting protrusion 401 can be an integrated design or a separate design. In some embodiments, the button shell 41 and the limiting protrusion 401 are integrally formed, which can be integrally formed by injection molding or metal casting. Of course, other methods can also be used, which are selected according to needs. In other embodiments, a separate design is adopted between the button shell 41 and the limiting protrusion 401, that is, the limiting protrusion 401 is installed on the button shell 41 by screwing, bonding or clamping. Exemplarily, a bonding member (not shown) is provided on the side of the limiting protrusion 401 facing the button shell 41, and the limiting protrusion 401 is bonded to the button shell 41 by the bonding member, which is conducive to improving assembly efficiency, and the limiting protrusion 401 can be replaced as needed after being worn, which is conducive to improving user experience. The bonding member can be a sticky member made of double-sided tape, glue or other sticky materials.

[0057] The limiting protrusion 401 can be made of elastic materials such as silicone or other materials such as plastic, and the specific material can be selected according to needs. In this embodiment, the limiting protrusion 401 is made of elastic materials such as silicone, so that when the user places or adjusts the mobile device, the risk of the limiting protrusion 401 scratching the surface of the mobile device can be reduced, which is conducive to improving the user experience.

[0058] In some embodiments, Figure 4-6As shown, the keyboard 1 also includes a weight block 5, which is arranged in the accommodating space 302, one end face of the weight block 5 abuts against the base 2, and the other end face of the weight block 5 abuts against the flexible circuit board group 43 of the key module 4. In this way, when the key cap 42 indirectly presses the flexible circuit board group 43 through the soft rubber part 44, the weight block 5 can support the flexible circuit board group 43 to prevent the flexible circuit board group 43 from being excessively deformed. Moreover, the provision of the weight block 5 can increase the overall weight of the keyboard 1, reduce the risk of tipping over when a heavy mobile device is placed in the accommodating slot 101, and is conducive to improving the user experience. The weight block 5 can be a metal block such as an iron block, or a heavy plastic block, or of course other blocks, as long as the overall weight of the keyboard 1 can be increased.

[0059] In some embodiments, please combine Figure 6 and Figure 7 The key module 4 includes a main keyboard area 402, along the direction of the base 2 toward the key module 4 (such as Figure 6 In the direction Z shown, the projection of the weight block 5 covers the main keyboard area 402. In this way, it is beneficial to increase the overall weight of the keyboard 1, avoid the center of gravity of the keyboard 1 being located near the four corners, and facilitate the keyboard 1 to stably carry the mobile device.

[0060] In some embodiments, see Figure 7 The key module 4 also includes an editing key area 403, a function key area 404, a numeric keypad area 405 and an indicator light area 406. Along the direction of the base 2 toward the key module 4, the projection of the weight-increasing block 5 covers the main keyboard area 402, the editing key area 403, the function key area 404 and the numeric keypad area 405. This is more conducive to increasing the overall weight of the keyboard 1, further conducive to the keyboard 1 stably carrying the mobile device, and conducive to the center of gravity of the keyboard 1 being in the center position.

[0061] In some embodiments, Figure 4 As shown, the keyboard 1 also includes a control panel 6, which is disposed on the middle frame plate 31 and located in the accommodating space 302. The control panel 6 is connected to the key module 4 so that the control panel 6 can input a signal according to the pressed key cap 42 and output corresponding characters or commands according to the control of the software.

[0062] In some embodiments, Figure 8 As shown, the keyboard 1 also includes at least two support rods 7, and at least two support rods 7 can be movably connected to the base 2. Each support rod 7 can extend from a side of the base 2 adjacent to the support protrusion 32, thereby increasing the contact area with the supporting surface (such as a desktop), indirectly increasing the resistance of the keyboard 1 to tipping over when the mobile device is placed in the accommodating groove 101, which is beneficial to improving the stability of placing the mobile device on the keyboard 1.

[0063] There are many ways in which the support rod 7 can be movably connected to the base 2. Exemplarily, the support rod 7 can rotate relative to the base 2, that is, a limit axis for the support rod 7 to rotate is set on the base 2, and the support rod 7 can be in a retracted state or an extended state relative to the base 2 according to the weight of the mobile device. When the weight of the mobile device is too heavy, the support rod 7 rotates relative to the limit axis to exceed the edge of the base 2. At this time, the support rod 7 is in an extended state relative to the base 2, which can reduce the risk of the keyboard 1 turning over as a whole. When the weight of the mobile device is appropriate, the support rod 7 can be rotated in the opposite direction relative to the limit axis until it coincides with the edge of the base 2. At this time, the support rod 7 is in a retracted state relative to the base 2. Exemplarily, the support rod 7 can be telescopic relative to the base 2, that is, a slide rail is set on the base 2, and the support rod 7 can slide on the slide rail. When it is necessary to increase the supporting force of the keyboard 1, the support rod 7 can be pulled out of the base 2.

[0064] In some embodiments, Fig. 9 As shown, the support protrusion 32 is movably connected to the middle frame plate 31, and the support protrusion 32 can move relative to the middle frame plate 31 in a direction away from the key module 4, that is, along Fig. 9 Move in the direction M shown in the figure to adjust the distance between the support protrusion 32 and the key module 4. In this embodiment, the middle frame plate 31 is provided with a notch 311, and the two side walls of the notch 311 are provided with guide grooves 312. The support protrusion 32 includes a protruding portion 321 and a connecting portion 322 connected to each other. The protruding portion 321 is protruding relative to the connecting portion 322. The side end of the connecting portion 322 is arranged in the guide groove 312 and can slide along the guide groove 312. In this way, when the protruding portion 321 is pulled, the support protrusion 32 slides along the guide groove 312 by the required distance, and the distance between the protruding portion 321 and the key module 4 is adjusted, thereby adjusting the position of the protruding portion 321 supporting the mobile device. Moreover, adjusting the position of the protruding portion 321 can also adjust the angle at which the mobile device is placed on the keyboard 1, which is convenient for users to choose and is conducive to improving user experience.

[0065] In some embodiments, Fig.10 and Fig.11 As shown, the keyboard 1 further includes a limit assembly 8, which is disposed on the middle frame plate 31 and partially exposed in the receiving slot 101. The limit assembly 8 is used to limit the mobile device in the length direction of the receiving slot 101 (such as Fig.10In the present embodiment, there are two groups of limit assemblies 8, each group of limit assemblies 8 comprises an elastic member 81 and a limit block 82, wherein the two elastic members 81 are arranged at intervals along the length direction of the receiving groove 101, one end of each elastic member 81 is connected to the middle frame plate 31, and the other end of each elastic member 81 is connected to the limit block 82, the bottom of the receiving groove 101 is provided with two guide grooves 102 arranged at intervals, a limit block 82 is slidably arranged in one guide groove 102 and partially exposed in the receiving groove 101, and the two limit blocks 82 are arranged relatively to clamp the mobile device together under the elastic force of the two elastic members 81.

[0066] When in use, it is only necessary to pull the two limit blocks 82 apart by a certain distance and put the elastic member 81 in a compressed state. When the mobile device is placed in the receiving slot 101, the two limit blocks 82 are released, and the two elastic members 81 recover their deformation to push the two limit blocks 82 to clamp the mobile device. In this way, the mobile device can be restricted from moving left and right in the receiving slot 101, which is conducive to reducing the impact of the vibration force generated when the user taps the key cap 42 on the mobile device, thereby improving the user experience.

[0067] The keyboard 1 provided in the embodiment of the present application comprises a base 2, a middle frame module 3 and a key module 4, wherein the middle frame module 3 comprises a middle frame plate 31 and a supporting protrusion 32 connected to each other, wherein the middle frame plate 31 is connected to the base 2, and the supporting protrusion 32 is provided protrudingly in a direction away from the base 2 relative to the surface of the middle frame plate 31; the key module 4 is detachably connected to the middle frame plate 31, and a limiting protrusion 401 is provided on the side of the key module 4 facing the supporting protrusion 32, and a preset spacing is provided between the key module 4 and the supporting protrusion 32, and a receiving groove 101 is constructed between the key module 4, the middle frame plate 31 and the supporting protrusion 32, wherein the limiting protrusion 401, the supporting protrusion 32 and the middle frame plate 31 are used together to constrain the mobile device placed in the receiving groove 101.
