Description

Technical Field

[0001] This utility model belongs to the field of folding keyboard technology, and in particular relates to a Bluetooth folding keyboard that can be locked in an unfolded state. Background Technology

[0002] Currently, commercially available foldable Bluetooth keyboards typically employ a two-part folding structure connected by a central hinge, facilitating storage and portability. However, in practical use, when the keyboard is placed on non-flat surfaces such as laps or sofas, the lack of stable support causes the two parts of the keyboard to fold automatically due to typing force or leg movement, leading to inconvenience during input or even the device slipping. Existing technology lacks an anti-folding locking design specifically for 'leg typing scenarios', therefore a simple and easy-to-operate locking mechanism is needed to ensure the keyboard remains stable and flat when unfolded. Utility Model Content

[0003] This utility model provides a lockable unfolded Bluetooth folding keyboard, which is implemented as follows: A lockable unfolded Bluetooth folding keyboard includes:

[0004] A first keyboard module and a second keyboard module are hinged together.

[0005] The first keyboard module has a storage groove on its back, and the second keyboard module has a locking groove on its back. The storage groove and the locking groove are respectively provided with a first locking block and a second locking block. The storage groove is provided with a locking rod. When the first keyboard module and the second keyboard module are flattened, the locking rod flips from the storage groove into the locking groove and engages with the second locking block.

[0006] Preferably, the locking rod has a U-shaped structure, and the two ends of the locking rod are provided with pivots, and the pivots are inserted into the side wall of the storage groove with shaft holes.

[0007] Preferably, the size of the first locking block is larger than the size of the second locking block.

[0008] Preferably, when the first keyboard module and the second keyboard module are unfolded, the first locking block and the second locking block are connected to each other to form an integral structure, and the distance between the shaft hole and the two ends of the integral structure formed by the first locking block and the second locking block is equal.

[0009] Preferably, both the first locking block and the second locking block are provided with latches, which are respectively located at both ends of the integral structure formed by the first locking block and the second locking block.

[0010] Preferably, both the first locking block and the second locking block are provided with a toggle groove.

[0011] Preferably, the first locking block is provided with a deformation groove, the deformation groove being positioned corresponding to the shaft hole. When the first locking block and the second locking block are aligned, the distance from the deformation groove to the edge of the first locking block and the distance between the deformation groove and the edge of the second locking block are equal.

[0012] Compared with the prior art, the embodiments of this application have the following main advantages:

[0013] In the lockable unfolded Bluetooth folding keyboard provided by this utility model, after the first locking block and the second locking block are connected to form an integral structure, the locking lever flips and locks the first locking block and the second locking block to maintain a flat and connected state. This allows the first keyboard module and the second keyboard module to maintain a flat state for a long time and prevents them from being folded again. The locking structure can maintain the flat state of the first keyboard module and the second keyboard module. In some environments where a stable supporting plane cannot be provided, the locking structure can maintain the flat state of the first keyboard module and the second keyboard module. By using its own limit to maintain flatness, the keyboard itself can meet the fixing function of keyboard use. Attached Figure Description

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a Bluetooth foldable keyboard that can be locked in an unfolded state, such as... Figures 1-5 As shown, the lockable unfolded Bluetooth folding keyboard includes:

[0024] A first keyboard module 110 and a second keyboard module 120 are hinged together. The internal circuit structure and keycap structure of the first keyboard module 110 and the second keyboard module 120 are completely the same as those of existing two-fold Bluetooth folding keyboards. This application adds a locking structure to the existing keyboard. The first keyboard module 110 and the second keyboard module 120 remain flush after rotation to form an integral plane. When the first keyboard module 110 and the second keyboard module 120 remain flush, the contact surface is a mating surface.

[0025] Specifically: The first keyboard module 110 has a storage groove 201 on its back, and the second keyboard module 120 has a locking groove 202 on its back. The front of the first keyboard module 110 and the second keyboard module 120 are the keycap surfaces. When folded, the front surfaces of the first keyboard module 110 and the second keyboard module 120 are close to each other, while the back surfaces become opposite surfaces after folding. The storage groove 201 and the locking groove 202 are both designed with embedded slots.

[0026] The storage groove 201 and the locking groove 202 are respectively provided with a first locking block 310 and a second locking block 320. The storage groove 201 is provided with a locking rod 200. When the first keyboard module 110 and the second keyboard module 120 are flattened, the locking rod 200 flips from the storage groove 201 into the locking groove 202 and engages with the second locking block 320. When folded, the locking rod 200 flips from the locking groove 202 into the storage groove 201 and engages with the first locking block 310. The first locking block 310 and the second locking block 320 are respectively spaced apart from the inner walls of the storage groove 201 and the locking groove 202 to form a space to accommodate the locking rod 200.

[0027] The specific function of the locking lever 200 is to keep the first locking block 310 and the second locking block 320 in a flat and aligned state after they are connected to form an integral structure. This allows the first keyboard module 110 and the second keyboard module 120 to remain in a flat state for a long time and prevents them from being folded again. The locking structure can maintain the flat state of the first keyboard module 110 and the second keyboard module 120. In some environments where a stable support plane cannot be provided, the locking structure can maintain the flat state of the first keyboard module 110 and the second keyboard module 120. By limiting the flatness, the keyboard itself can meet the fixing function of keyboard use.

[0028] In a preferred embodiment of this invention, the locking lever 200 has a U-shaped structure and two ends of the locking lever 200 are provided with pivots. The pivots are inserted into the side wall of the storage groove 201 and are provided with shaft holes 203. When the first keyboard module 110 and the second keyboard module 120 are unfolded, the first locking block 310 and the second locking block 320 are connected to each other to form an integral structure. The shaft holes 203 are equidistant from the two ends of the integral structure formed by the first locking block 310 and the second locking block 320.

[0029] The first locking block 310 is provided with a deformation groove 303, which corresponds to the position of the shaft hole 203. When the first locking block 310 and the second locking block 320 are aligned, the distance from the deformation groove 303 to the edge of the first locking block 310 and the distance from the deformation groove 303 to the edge of the second locking block 320 are equal.

[0030] The locking lever 200 utilizes the deformation characteristics of the U-shaped structure and the space provided by the deformation groove 303 to help insert the locking lever 200 into the shaft hole 203. The first locking block 310 and the second locking block 320 have the same width but different lengths, ensuring that the locking lever 200 can flip and engage with the first locking block 310 and the second locking block 320 during the flipping process. The first locking block 310 and the second locking block 320 remain flush with the edges of the adjacent mating surfaces of the receiving groove 201 and the locking groove 202, respectively, ensuring that the first keyboard module 110 and the second keyboard module 120 do not interfere with each other after unfolding.

[0031] As a preferred embodiment of this embodiment, both the first locking block 310 and the second locking block 320 are provided with latches 301, and the latches 301 are respectively provided at both ends of the integral structure formed by the first locking block 310 and the second locking block 320.

[0032] In this embodiment, the latch 301 adopts the principle of existing technology and mainly engages and fixes the locking rod 200 with a circular cross-section; both the first locking block 310 and the second locking block 320 are provided with actuation grooves 302, which are arranged between the latches 301; the actuation grooves 302 provide a certain space for the locking rod 200 to perform unlocking operations.
