Description

Technical Field

[0001] The present application belongs to the technical field of computer peripheral auxiliary equipment, and in particular, relates to a multifunctional folding keyboard capable of modular combination. Background Art

[0002] The keyboard is a commonly used input device. The keyboard can be connected to terminal devices such as computers and tablet computers through wired or wireless means. The keyboard can be used to input English letters, Chinese characters, numbers, punctuation marks, etc. into the terminal device, thereby issuing commands to the terminal device, inputting data, etc., so that the terminal device can perform corresponding operations and applications according to the input instructions.

[0003] Common keyboard specifications include full-size keyboards, 96-key keyboards, and reduced-size keyboards of 87 keys, 75%, 60% or 40%. Among them, the full-size keyboard has 104 keys, is about 44 cm long, and includes a numeric keypad; the 96-key keyboard is about 34 cm long. Both types of keyboards are commonly used keyboards with complete keys, but they take up a large space, especially because they are too long, which is not conducive to storage and carrying. The above-mentioned smaller-size 87-key, 75%, 60% or 40% reduced-size keyboards have shortened lengths to reduce the space they take up, making them easier to store and carry, but they do not have complete keys, which affects actual use.

[0004] In this regard, foldable keyboards are introduced on the market. This type of foldable keyboard divides the keyboard into two or three parts, which can be folded together to reduce the length of the keyboard, reduce the overall volume of the keyboard, and facilitate storage and carrying. However, this type of foldable keyboard will increase the overall thickness. In order to reduce the thickness after folding, the design direction of reducing the keys as much as possible is adopted. Usually, only the main key area of ​​the keyboard (sub-keys and symbol key area) is provided, and there is no function key area (such as numeric keys, touchpad, etc.), resulting in fewer functions on the keyboard, and no consideration of extended functions. Therefore, the foldable keyboards currently on the market do not meet the usage needs of today's consumers. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a foldable keyboard to solve the technical problem that the foldable keyboard in the prior art has a single function and lacks extended functions.

[0006] To achieve the above purpose, the technical solution adopted by the present application is: to provide a foldable keyboard, comprising:

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0038] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] Traditional folding keyboards are divided into two or three parts, which can be folded together to reduce the length of the keyboard, reduce the overall size of the keyboard, and facilitate storage and carrying. In order to reduce the thickness after folding, traditional folding keyboards cut off uncommon keys or function keys on the keyboard, resulting in a lack of functions on the keyboard, and no consideration of extended functions.

[0041] In order to improve the keys and extended functions on the folding keyboard, in the related art, there is a setting of adding functional modules, for example: changing at least a part of the key area on the original full-size keyboard into a functional module; or adding a part with a set function, so that the part is used as an extended functional module, and this functional module can be a module with auxiliary functions such as a handwriting board, thereby increasing the function of the folding keyboard. However, this structure directly changes a part of the original folding keyboard into a functional module, or directly adds a functional module as a foldable part on the folding keyboard. Therefore, this functional module is fixed, and the keyboard has been set at the factory, and it cannot be changed later, and it cannot meet different usage requirements. If in order to adapt to different usage requirements, it is necessary to add keyboard styles with different functional modules, which causes the keyboard manufacturer to increase the production line and production costs. Consumers also have to purchase multiple keyboards with different functional modules according to usage requirements, which increases the cost of use.

[0042] The embodiment of the present application provides a new type of folding keyboard, which improves the extended function part of the folding keyboard so that the extended function part can be replaced and set, so that consumers can add corresponding functional modules according to their usage requirements. It not only expands the performance of the folding keyboard, but also adapts to different usage requirements, thereby reducing production costs and usage costs, and effectively solves the technical problems of the traditional folding keyboard with single functions and lack of extended functions. It is now described in detail.

[0043] Please also read Figure 1 and Figure 2 The folding keyboard includes a main keyboard 1 and an installation disk 2.

[0044] The main keyboard 1 has a main key area of ​​a conventional keyboard, and can be provided with a full-size keyboard, a 96-key keyboard, or a reduced-size keyboard of 87 keys, 75%, 60% or 40%. The size can be set according to the size requirements, which is not specifically limited here.

[0045] The installation disk 2 is hinged to one side of the main keyboard 1, so that the installation disk 2 can be folded on the main keyboard 1 to shorten the overall length of the keyboard, which is convenient for storage and carrying; when the keyboard is needed, the folded keyboard can be opened like a book, so that the installation disk 2 carrying the functional module 3 can be flattened for use. The installation disk 2 can be connected to any side of the main keyboard 1, such as the left, right, upper, and lower sides of the main keyboard 1. By means of a hinge, the installation disk 2 can be rotated with the hinge as the axis, so that it is convenient to fold it on the main keyboard 1; or, it can be opened from the main keyboard 1 for use.

[0046] A detachable functional module 3 is provided on the installation disk 2. The functional module 3 may be a numeric keypad, a charger, a docking station, a touchpad, a handwriting board, etc. The user may selectively install the functional module 3 on the installation disk 2 according to usage requirements, so that the installation disk 2 can carry the functional module 3 and be folded and stored or opened for use on the main keyboard 1.

[0047] The hinge between the installation disk 2 and the main keyboard 1 has an electrical connection mechanism, and the function module 3 is electrically connected to the main keyboard 1 through the electrical connection mechanism, so that the function module 3 can use the power supply on the main keyboard 1, allowing the main keyboard 1 and the function module 3 to operate together for easy use.

[0048] Compared with the prior art, the folding keyboard provided in the embodiment of the present application includes a main keyboard 1 and an installation disk 2. A detachable functional module 3 is provided on the installation disk 2. The installation disk 2 is hinged to one side of the main keyboard 1 so that the installation disk 2 can carry the functional module 3 and be folded onto the main keyboard 1 for easy storage and carrying.

[0049] Among them, since the functional module 3 is detachably arranged, the user can select a corresponding functional module 3 to be installed on the installation disk 2 according to usage requirements, so as to be used together with the main keyboard 1.

[0050] On the one hand, the folding keyboard of the present application can be flexibly matched with different types of functional modules 3 to achieve a modular combination mode, which is convenient to use and effectively improves the overall performance of the folding keyboard. On the other hand, since the installation disk 2 on the folding keyboard is compatible with the installation and combined use of different functional modules 3, the manufacturer does not need to set up additional production lines according to different functional modules 3, and the user does not need to purchase the same type of keyboard with different functional modules 3 for different functional modules 3, which effectively reduces the production cost and the user's use cost.

[0051] It should be noted that in other embodiments (not shown), in the scenario where there is no mandatory requirement for the thickness of the folded keyboard, the installation disk 2 can also be hinged on the four sides, or any two opposite sides, or any two adjacent sides of the main keyboard 1. Different functional modules 3 can be installed on each installation disk 2 and stored on the main keyboard 1 in a folded manner, thereby maximizing the use of the peripheral space of the main keyboard 1 and effectively improving the overall expansion performance of the keyboard.

[0052] For the structure of the mounting plate 2, in one embodiment of the present application, please refer to Figure 2 and Figure 3 The mounting plate 2 includes a base plate 21 and a connecting portion 4 arranged on the base plate 21 , and the functional module 3 is mounted on the base plate 21 .

[0053] Preferably, the surface area of ​​the base plate 21 is not less than the overall area of ​​the functional module 3, that is, the surface area of ​​the base plate 21 is greater than or equal to the overall area of ​​the functional module 3, so that the base plate 21 can well support the functional module 3 and effectively improve the support stability of the functional module 3.

[0054] The connecting portion 4 is used to be hinged with the main keyboard 1, and hinges 41 connected to the main keyboard 1 are provided at both ends of the connecting portion 4. In this embodiment, the connecting portion 4 can preferably be a strip-shaped piece with the same thickness as the main keyboard 1 and a width similar to that of the mounting plate 2, and the connecting portion 4 is located on one side edge where the bottom plate 21 is connected to the main keyboard 1. Preferably, the connecting portion 4 is integrally connected with the bottom plate 21 to ensure the structural strength of the connecting portion 4.

[0055] Thus, the installation tray 2 carries the functional module 3 via the bottom plate 21 and is hinged to the main keyboard 1 via the connecting portion 4, so that the installation tray 2 can carry the functional module 3 and be folded or unfolded onto the main keyboard 1 for use, which is convenient for storage and carrying.

[0056] Regarding the hinges 41 at both ends of the connecting portion 4, in the embodiment of the present application, please refer to Figure 3 The hinge 41 can preferably be a movable hinge respectively arranged at the two ends of the connecting part 4, and connected to the main keyboard 1. The two ends of the hinge are respectively connected to the main keyboard 1 and the end fixing plate 42 of the connecting part 4 through a rotating shaft. The fixing plate 42 is integrally connected to the bottom plate 21 so that the installation plate 2 and the main keyboard 1 can move relative to each other.

[0057] The upper half of the joint surface between the main keyboard 1 and the connecting part 4 is preferably an arcuate surface 11a (the same joint surface part on the connecting part 4 is not shown in the figure), so that the connecting part 4 and the main keyboard 1 can be folded toward each other. The lower half of the joint surface between the connecting part 4 and the main keyboard 1 is preferably a vertical plane 11b (the same joint surface part on the connecting part 4 is not shown in the figure). After the connecting part 4 and the main keyboard 1 are opened, the vertical plane 11b of the lower half of the joint surface between the connecting part 4 and the main keyboard 1 abuts against each other, thereby limiting the opening range of the installation disk 2. In this embodiment, the maximum angle of the connecting part 4 when the main keyboard 1 is opened can be preferably set to 180 degrees, so that the installation disk 2 can be completely flattened with the main keyboard 1 after opening.

[0058] For the installation structure of the functional module 3 on the installation disk 2, in one embodiment of the present application, please refer to Figure 3 and Figure 4, a magnetic member 43 is provided on the connection part 4, and the magnetic member 43 is used to magnetically fix the functional module 3 arranged on the bottom plate 21. In this embodiment, the connection part 4 is arranged on one side of the installation plate 2 so as to be hingedly matched with the main keyboard 1, and the other side of the connection part 4 away from the main keyboard 1 can be set as a magnetic surface 43a. In coordination, one side surface of the functional module 3 is set as a magnetic surface 31 for magnetic matching or a metal surface that can be magnetically attracted.

[0059] Thus, when the functional module 3 is placed on the bottom plate 21, the functional module 3 can be automatically magnetically connected to the connecting portion 4, which is convenient for assembly. In actual operation, the functional module 3 can slide onto the connecting portion 4 using the bottom plate 21 as a guide plate, and when the magnetic surface 31 on the functional module 3 touches the magnetic surface 43a on the connecting portion 4, it is automatically magnetically fixed, effectively improving assembly efficiency.

[0060] For the installation structure of the functional module 3 on the installation disk 2, please refer to another embodiment of the present application. Figure 3 and Figure 4 A buckle groove 44 is provided on the connecting portion 4, and a buckle block 32 is provided on the functional module 3 for buckling with the buckle groove 44. By means of the mutual buckling of the buckle groove 44 and the buckle block 32, the functional module 3 is fixed on the mounting plate 2, effectively ensuring the accuracy of mutual alignment.

[0061] On the basis of the above, the buckle groove 44 can preferably be arranged as a slide groove arranged in the height direction of the connecting portion 4, and the upper surface of the connecting portion 4 has a buckle groove port for the buckle block 32 to slide into. Figure 5 and Figure 6 As shown, the side of the buckle block 32 has a protruding buckle hook 321, and the buckle groove 44 has an inner concave cavity 441 for the buckle hook 321 to buckle into.

[0062] In this way, the functional module 3 can slide into the buckle groove 44 from the buckle groove 44 port located on the upper surface of the connecting part 4 through the buckle block 32, and at the same time, the buckle hook 321 on the buckle block 32 is buckled into the inner concave cavity 441 of the buckle groove 44, so that the functional module 3 is fixedly connected to the connecting part 4, which is conducive to narrowing the gap between the functional module 3 and the connecting part 4.

[0063] In this embodiment, if Figure 5 and Figure 6 As shown, the buckle block 32 is a T-shaped structure, and the two sides of the buckle block 32 protrude outward to form double-sided hooks 321. The shape of the buckle groove 44 matches the buckle block 32 and is a T-shaped groove body of a matching size, so that the buckle block 32 can lock the connection position of the functional module 3 after being buckled into the buckle groove 44.

[0064] In other embodiments (not shown), the buckle block 32 may also be an L-shaped structure, that is, any side of the buckle block 32 protrudes outward to form a single-sided hook 321, and the shape of the buckle groove 44 matches the buckle block 32 to form an L-shaped groove body of matching size, thereby achieving the same technical effect.

[0065] For the electrical connection structure between the functional module 3 and the main keyboard 1, in one embodiment of the present application, please refer to Figure 3 , Figure 4 and Figure 7 The functional module 3 is provided with an electrical contact 33 for electrical connection. Specifically, the electrical contact 33 is arranged on the splicing surface of the functional module 3 for splicing with the connecting part 4.

[0066] The electrical connection mechanism includes an electrical contact 45 disposed on the connection portion 4 . The electrical contact 45 is used to contact the electrical contact 33 on the functional module 3 , so that the functional module 3 and the connection portion 4 are electrically connected.

[0067] Among them, Figure 7 As shown, a wire hole 46 is also provided on the connecting portion 4, and the electrical connection mechanism also includes a flexible cable 12 arranged on the main keyboard 1. After the flexible cable 12 is led out from the main keyboard 1, it extends into the interior of the connecting portion 4 from the wire hole 46 and is connected to the electrical contact 45.

[0068] In this way, the flexible cable 12 can adapt to the folding movement of the foldable keyboard and ensure the stability of the electrical connection at the same time.

[0069] In addition, based on the above electrical connection structure, in order to ensure the connection accuracy and stability between the electrical contact 33 and the electrical contact 45 , the installation structure of the functional module 3 on the installation plate 2 can adopt the above fixing method combining the magnetic attraction and the buckle groove 44 .

[0070] like Figure 3 and Figure 4 As shown, on the one hand, in order to ensure the stability of electrical contact, the electrical contact 33 is set on the magnetic surface 31 of the functional module 3, and correspondingly, the electrical contact 45 on the connecting part 4 is set on the magnetic surface 43a, and the magnetic attraction between the connecting part 4 and the functional module 3 is utilized to ensure that the electrical contact 33 and the electrical contact 45 are in contact with each other.

[0071] On the other hand, in order to ensure the connection accuracy, the buckle groove 44 on the connecting part 4 cooperates with the buckle block 32 on the functional module 3, so that the joint part of the functional module 3 and the connecting part 4 is automatically positioned to lock the corresponding positions of the electric contact 33 and the electric contact 45, so that the electric contact 33 and the electric contact 45 are automatically aligned during the installation process, thereby playing a fool-proof installation role. In addition, by adopting the buckle connection structure of the buckle groove 44 and the buckle block 32, the buckle hook 321 on the buckle block 32 and the inner concave cavity 441 in the buckle groove 44 can tighten the gap between the functional module 3 and the connecting part 4, so that the joint surfaces of the two are mutually fitted, effectively ensuring that the electric contact 33 and the electric contact 45 are in contact, thereby improving the stability of the electrical connection.

[0072] In practical applications, the electrical contacts 33 on the functional module 3 are protrudingly arranged so as to better contact the electrical contacts 45 on the connecting portion 4. The protruding electrical contacts 33 are easily touched by foreign objects, which may cause a short circuit risk.

[0073] Here, in another embodiment of the present application (not shown), an elastic telescopic structure capable of shielding the electrical contact 33 may preferably be provided on the functional module 3, so that when the functional module 3 is assembled on the connecting part 4, it is triggered to expose the electrical contact 33 and contact the electrical contact 45 on the connecting part 4.

[0074] As an example, the elastic telescopic structure (not shown) may preferably include a movable sleeve sleeved on the electrical contact 33, and a push rod is provided on the splicing surface of the connecting part 4, so that when the functional module 3 and the connecting part 4 are spliced ​​together, the push rod pushes the movable sleeve to move, so that the electrical contact 33 can be exposed from the movable sleeve and smoothly contact the electrical contact 45 to achieve electrical connection.

[0075] The structure of functional module 3 includes but is not limited to the following forms:

[0076] In one embodiment of the present application, see Figure 8 The functional module 3 is preferably a charger 3a, and the charger 3a has a wireless charging module 34. The wireless charging module 34 is electrically connected to the cable 11 on the main keyboard 1 through the electrical contact 33 to obtain power.

[0077] The upper surface of the charger 3a is a charging contact surface 341 of the wireless charging module 34. Preferably, the charging contact surface 341 is a plane, so that when the mounting plate 2 carrying the functional module 3 is folded on the main keyboard 1, the charging contact surface 341 can be in smooth contact with the keys on the main keyboard 1, thereby avoiding squeezing the keys on the main keyboard 1, effectively protecting the keys on the main keyboard 1, and extending the service life of the keys.

[0078] In this way, the wireless charging function is added to the foldable keyboard, and the user can place a mobile intelligent terminal with wireless charging function, such as a smart phone, on the charger 3a to achieve wireless charging.

[0079] In another embodiment of the present application, see Fig. 9 The functional module 3 is preferably an expansion dock 3b, and the expansion dock 3b is provided with a plurality of expansion interfaces 35, and the types of these expansion interfaces 35 may include but are not limited to TYPE-C, USB, HDMI, etc. The expansion function is added to the foldable keyboard, which is convenient for data connection with different terminal devices and is conducive to improving the connection adaptability of the keyboard.

[0080] A plurality of expansion interfaces 35 are distributed on the periphery of the expansion dock 3b. Each expansion interface 35 may include one or more, which may be specifically arranged according to the available space on the functional module 3, and is not specifically limited here.

[0081] Preferably, the upper surface of the expansion dock 3 b is a flat surface to prevent the expansion dock 3 b from squeezing the keys on the main keyboard 1 when the expansion dock 3 b is folded on the main keyboard 1 , thereby effectively protecting the keys on the main keyboard 1 .

[0082] For the structure of the entire folding keyboard, in one embodiment of the present application, please refer to Fig.10 The foldable keyboard also includes at least one auxiliary keyboard 5, which can preferably be a numeric keyboard or a specially set shortcut function key keyboard, etc., which is not specifically limited here.

[0083] like Fig.10 As shown, the auxiliary keyboard 5 and the mounting plate 2 are respectively hinged on opposite sides of the main keyboard 1, so that the auxiliary keyboard 5 and the mounting plate 2 can be folded on the main keyboard 1 facing each other.

[0084] Preferably, the total area of ​​the auxiliary keyboard 5 and the mounting plate 2 combined is similar to the area of ​​the main keyboard 1. When the auxiliary keyboard 5 and the mounting plate 2 are folded on the main keyboard 1 facing each other, the total area of ​​the auxiliary keyboard 5 and the mounting plate 2 combined is the same as the area of ​​the main keyboard 1. In this way, the space on the opposite sides of the main keyboard 1 is maximized, making the overall structure of the keyboard bilaterally symmetrical, thereby improving the extended function of the keyboard, increasing the key area of ​​the keyboard, and effectively improving the overall performance and overall aesthetics of the keyboard.

[0085] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
