[0036] For the convenience of understanding the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is expressed as "fixed to" another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween. When an element is expressed as "connected to" another element, it can be directly connected to the other element, or there can be one or more intermediate elements therebetween. The terms "upper", "lower", "inner", "outer", "vertical", "horizontal", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention 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 to the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0037] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0038] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] With the popularization and complication of written records, handwriting has gradually become inefficient and error-prone. Especially after the Industrial Revolution, with the explosion of information processing volume, people need a tool that can input text quickly and accurately 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 and greatly improved the efficiency of information processing.

[0040] Keyboards are used in all walks of life. For example, in the teaching industry, keyboards provide an efficient interaction method for online education platforms. Students can input answers, complete assignments, and participate in online discussions through keyboards. In an online exam system, students can use keyboards to quickly and accurately input text answers, which greatly improves the answering efficiency compared with handwriting input. Another example is in programming teaching. The keyboard is a key tool for students to communicate with the computer. By inputting code instructions through the keyboard, students can practice programming ideas and cultivate logical thinking and problem-solving abilities. In multimedia teaching, keyboards can facilitate teachers to produce and demonstrate courseware. Teachers can use keyboards to input text, edit picture annotations, etc., making the teaching content more rich and vivid. Thus, it can be seen that keyboards have played an indispensable role in people's lives.

[0041] During the teaching process, due to software interface limitations or management permission limitations, students are unable to switch the computer's display screen to view relevant materials. They have to hold mobile devices such as mobile phones or tablets to view materials while operating the computer according to the materials on the mobile devices. If the mobile devices are placed on the desktop, it is difficult to view the materials at a suitable angle, which is not conducive to students operating the keyboard.

[0042] The inventors of this application found through research that the keyboard structures on the market are relatively simple and have relatively single functions. When placing mobile devices such as mobile phones or tablets, the keyboard may tilt due to the different weights of the mobile devices. For this reason, the inventors of this application found through research that the keyboard structure can be changed to increase the weight of the keyboard, thereby improving the phenomenon of tilting when the mobile device is placed on the keyboard. The specific solution is as follows:

[0043] As shown Figures 1-3 in FIG. 1, a keyboard 1 provided by one embodiment of the present application includes a base 2, a middle frame module 3, a key module 4, and a weight block 5. The middle frame module 3 is connected to the base 2, the key module 4 is connected to the middle frame module 3. The middle frame module 3 is provided with an accommodation space 302, the weight block 5 is disposed in the accommodation space 302, and one end surface of the weight block 5 abuts against the base 2, and the other end surface of the weight block 5 abuts against the key module 4. Wherein, at least a part of the structure of the key module 4 is located between the base 2 and the middle frame module 3, and an accommodation groove 101 for accommodating and supporting a mobile device is formed by enclosing between one end of the middle frame module 3 protruding relative to the key module 4, the key module 4, and the base 2. The accommodation groove 101 is located on a side of the middle frame module 3 away from the base 2.

[0044] As shown Figure 4 in FIG. 2 Figure 4 shows a schematic diagram of a mobile device placed in the accommodation groove 101 of the keyboard 1 in one embodiment. The mobile device is supported by the middle frame module 3 and the key module 4 together. Through the above structure, setting the weight block 5 can increase the overall weight of the keyboard 1, reduce the risk of tipping when a relatively heavy mobile device is placed in the accommodation groove 101, and is beneficial to improving the user experience.

[0045] In some embodiments, as shown Figure 3 in FIG. 3 Figure 5 a support structure 21 is provided in the base 2. 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. Of course, it can also be other structures as long as it can play a supporting role. In this embodiment, the support structure 21 adopts a combined structure of the support column 211 and the reinforcing rib 212. In this way, it can not only enhance the strength of the base 2, but also support other components.

[0046] In some embodiments, please refer to FIG. 3 again Figure 2 or Figure 3 FIG. 4, several support bars 22 are provided on one end surface of the base 2 away from the middle frame plate 31. The several support bars 22 are spaced apart 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 several support bars 22 are beneficial to reducing the contact area between the base 2 and the support surface and reducing the risk of the base 2 being contaminated by the support surface.

[0047] In some embodiments, as shown Figures 1-2 in FIG. 5, the accommodation groove 101 is in the length direction of the keyboard 1 (such as Figure 1On both sides in the direction L shown, it is open. In other words, there are no blocking objects at both ends of the receiving groove 101 in the length direction of the keyboard 1, which facilitates the user to clean the dust, dander or other pollutants falling into the receiving groove 101.

[0048] In some embodiments, as Figure 2 shown, the middle frame module 3 includes a connected middle frame plate 31 and a support protrusion 32. The middle frame plate 31 is connected to the base 2, and the support protrusion 32 protrudes in a direction away from the base 2 (such as the direction Z shown in Figure 2 ) relative to the surface of the middle frame plate 31, and the support protrusion 32 and the button module 4 are located on the same side of the middle frame plate 31. Among them, there is a preset distance between the support protrusion 32 and the button module 4, and a receiving groove 101 is constructed between the middle frame plate 31, the support protrusion 32 and the button module 4. In this way, the back of the mobile device can lean on the support protrusion 32, as Figure 3 shown, and the side edges of the mobile device respectively abut against the middle frame plate 31 and the button module 4, so that the mobile device is restricted and will not directly tip over relative to the base 2, which is convenient for the user to view the mobile device while operating the keyboard 1 and is beneficial to improving the user experience.

[0049] 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 it can support the mobile device. For example, the support protrusion 32 extends along the side close to the button module 4 relative to the middle frame plate 31, or the support protrusion 32 extends along the side away from the button module 4 relative to the middle frame plate 31. In this embodiment, as Figure 2 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 button 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, more light emitted by the mobile device can be projected onto 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 more light emitted by the mobile device to be projected onto the user and reduces the risk of reflection caused by external light shining on the mobile device. Specifically, α can be 60°, 70°, 75°, 80° or 85°.

[0050] In some embodiments, as Figure 2As 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.

[0051] In some embodiments, Figure 2 , Figure 3 , Figure 5 and Figure 6 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, and the first side end 411 is closer to the support protrusion 32 than the second side end 412. 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 button 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 button 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 the button is installed on the bearing surface 413, since the bearing surface 413 is tilted relative to the middle frame plate 31, the button is also tilted relative to the middle frame plate 31, which is conducive to user pressing and improves the user experience.

[0052] In some embodiments, Figures 5-6 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 6 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.

[0053] In some embodiments, please refer again to Figure 2, on one side of the key module 4 facing the supporting protrusion 32, that is, on the first side end 411, there is a limiting protrusion 401. The limiting protrusion 401 is used to abut against the mobile device, reducing the risk of the mobile device tipping over due to the smooth surface of the side of the key module 4 facing the supporting protrusion 32, which is beneficial to improving the stability of the mobile device placed in the receiving groove 101 of the keyboard 1. In this embodiment, the limiting protrusion 401 is located on the surface of the first side end 411 of the key housing 41 facing the supporting protrusion 32.

[0054] The key housing 41 and the limiting protrusion 401 can be integrally designed or separately designed. In some embodiments, the key housing 41 and the limiting protrusion 401 are integrally formed, which can be integrally formed by injection molding or by metal casting. Of course, other methods can also be used, and specific selection is based on needs. In other embodiments, a separate design is adopted between the key housing 41 and the limiting protrusion 401, that is, the limiting protrusion 401 is installed on the key housing 41 by screwing, bonding or clamping. Exemplarily, a bonding member (not shown in the figure) is provided on the surface of the limiting protrusion 401 facing the key housing 41, and the limiting protrusion 401 is bonded to the key housing 41 through the bonding member, which is beneficial to improving the assembly efficiency, and the limiting protrusion 401 can be replaced according to needs after wear, which is beneficial to improving the user experience. The bonding member can be a double-sided tape, glue or other viscous members made of viscous materials.

[0055] The limiting protrusion 401 can be made of elastic materials such as silicone, or made of other materials such as plastic, and specific selection can be made according to needs. In this embodiment, the limiting protrusion 401 is made of elastic materials such as silicone. In this way, 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 beneficial to improving the user experience.

[0056] In some embodiments, such as Figure 5 and Figure 6 shown, 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 overly deformed. The weight block 5 can be a metal block such as an iron block, or a plastic block with a heavy mass. Of course, it can also be others, as long as it can increase the overall weight of the keyboard 1.

[0057] In some embodiments, please refer to Figure 3 and Figure 7 , the key module 4 includes a main keyboard area 402, along the direction of the base 2 facing the key module 4 (such as Figure 3In the shown direction Z), the orthographic projection of the weight increasing 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 is beneficial for the keyboard 1 to stably carry the mobile device. It should be noted here that the orthographic projection of the weight increasing block 5 can partially cover the main keyboard area 402 or completely cover the main keyboard area 402. The size of the weight increasing block can be specifically set according to needs.

[0058] In some embodiments, please refer to Figure 3 and Figure 7 , the key module 4 further 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 from the base 2 towards the key module 4 (such as Figure 3 the shown direction Z), 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. In this way, it is more beneficial to increase the overall weight of the keyboard 1, further beneficial for the keyboard 1 to stably carry the mobile device, and beneficial for the center of gravity of the keyboard 1 to be at the central position.

[0059] In some embodiments, as Figure 5 shown, the keyboard 1 further includes a control board 6. The control board 6 is disposed on the middle frame plate 31 and located within the accommodation space 302. The control board 6 is connected to the key module 4 so that the control board 6 can input signals according to the pressed key caps 42 and output corresponding characters or commands according to the control of the software.

[0060] In some embodiments, as Figure 8 shown, the keyboard 1 further includes at least two support rods 7. The at least two support rods 7 are all movably connected to the base 2. Each support rod 7 can extend from the side of the base 2 adjacent to the support protrusion 32. In this way, the contact area with the support surface (such as a desktop) can be increased, indirectly increasing the resistance to tipping of the keyboard 1 when the mobile device is placed in the accommodation groove 101, which is beneficial to improving the stability of placing the mobile device on the keyboard 1.

[0061] There are various ways for the support rod 7 to be movably connected to the base 2. Exemplarily, the support rod 7 can rotate relative to the base 2, that is, a limiting shaft for the support rod 7 to rotate is provided on the base 2. According to the weight of the mobile device, the support rod 7 can be in a retracted state or an extended state relative to the base 2. When the weight of the mobile device is too heavy, the support rod 7 rotates relative to the limiting shaft beyond 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 overall flipping of the keyboard 1. When the weight of the mobile device is appropriate, the support rod 7 can be rotated in the opposite direction relative to the limiting shaft 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 provided 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 from the base 2.

[0062] In some embodiments, as Figure 9 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 Figure 9 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 guide grooves 312 are provided on both side walls of the notch 311. The support protrusion 32 includes a connected protrusion part 321 and a connecting part 322. The protrusion part 321 protrudes relative to the connecting part 322. The side end of the connecting part 322 is arranged in the guide groove 312 and can slide along the guide groove 312. In this way, when the protrusion part 321 is pulled, the support protrusion 32 can slide the required distance along the guide groove 312, realizing the adjustment of the distance between the protrusion part 321 and the key module 4, thereby adjusting the position where the protrusion part 321 supports the mobile device. Moreover, adjusting the position where the protrusion part 321 is located 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 beneficial to improving the user experience.

[0063] In some embodiments, as Figure 10 shown in Figure 11 the figure, the keyboard 1 further includes a limiting component 8. The limiting component 8 is arranged on the middle frame plate 31 and partially exposed in the receiving groove 101. The limiting component 8 is used to limit the mobile device in the length direction of the receiving groove 101 (such as Figure 10In this embodiment, there are two groups of limit assemblies 8, each group of limit assemblies 8 includes 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, and the bottom of the receiving groove 101 is provided with two guide grooves 102 arranged at intervals, and 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.

[0064] 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.

[0065] The keyboard 1 provided in the embodiment of the present application comprises a base 2, a middle frame module 3, a weight block 5 and a key module 4.
