Description

Technical Field

[0001] This utility model relates to the field of computer input device technology, and in particular to a folding multi-mode mechanical keyboard. Background Technology

[0002] As the core input device for operating computer equipment, the keyboard is mainly used to input instructions and data into electronic systems. It is widely used in personal computers, mobile terminals, industrial control equipment and smart terminals. With the popularization of mobile office, remote collaboration and portable computing platforms such as ultra-thin laptops, tablets, 2-in-1 devices and handheld game consoles, users have put forward higher requirements for the portability, flexibility and multi-scenario adaptability of input peripherals.

[0003] Currently, traditional full-size mechanical keyboards have long been favored by professional users due to their excellent key feel, high actuation accuracy, long lifespan, and good structural rigidity. However, they generally have inherent characteristics such as large size, heavy weight, and fixed and unchangeable structure, which show obvious limitations in non-fixed office environments or when carried around, making it difficult to meet the dual needs of modern users for high performance and high portability. To improve portability, various alternative solutions have emerged in existing technologies, among which the most typical is the split keyboard design. This type of keyboard divides the traditional keyboard into two independent functional units along the center line. When using it, the two units can be placed separately or together in the natural position of both hands to conform to the ergonomic angle and reduce wrist fatigue. However, most products are prone to relative wobbling and misalignment of the left and right units when used together, resulting in discontinuous keycap arrangement and inconsistent pressing feel, which seriously affects typing smoothness and user experience.

[0004] Therefore, there is an urgent need for a foldable multi-mode mechanical keyboard that can maintain a high-rigidity and stable connection when unfolded, achieve compact folding when stored, and support multiple connection modes such as wired, Bluetooth and 2.4GHz wireless, so as to balance high-performance input experience and ultimate portability to meet the diverse and mobile usage needs of modern users. Utility Model Content

[0005] To overcome the shortcomings of existing traditional full-size mechanical keyboards, such as large size, non-foldability, and difficulty in meeting the portability needs of mobile office scenarios, and the fact that existing split keyboards are prone to problems such as left and right unit wobbling, misalignment, or loose splicing when used together, which affect the typing experience and overall rigidity, this utility model provides a foldable multi-mode mechanical keyboard.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a folding multi-mode mechanical keyboard, comprising a left keyboard and a right keyboard. The surfaces of both the left and right keyboards are regularly arranged with standard keycap arrays. Guide grooves are provided on the front and rear sides of the interior of both the left and right keyboards. Slider blocks are slidably disposed within the guide grooves. Multiple first elastic elements connect the sliders to the inner walls of the guide grooves. Three hinges, arranged horizontally and hinged to each other, are provided between the sliders of the left and right keyboards, forming a three-segment linkage folding structure. An indicator light is provided on the surface of the left keyboard.

[0007] Furthermore, the left keyboard has a horizontally oriented groove running along the front-to-back direction, and a vertically slidable pressing rod is installed inside the groove. One end of the pressing rod extends rearward from the groove and protrudes from the surface of the left keyboard, with a lever fixed to its end. Both ends of the pressing rod are fixedly connected to locking blocks. The right keyboard has locking grooves on both the front and back sides that match the locking blocks. Multiple guide rods are evenly spaced along the axial direction on the pressing rod. The left keyboard has guide holes that slide with the guide rods. A second elastic element is sleeved on the guide rod, and both ends of the second elastic element are fixedly connected to the pressing rod and the interior of the left keyboard, respectively.

[0008] Furthermore, both the left and right keyboards have rotatable pivots at the rear corners of their bottom surfaces, and support blocks are mounted on the pivots.

[0009] Furthermore, LED light strips are embedded in the front surfaces of the left and right keyboards.

[0010] Furthermore, a first magnet is provided on the left side of the bottom surface of the left keyboard, and a second magnet is provided on the right side of the bottom surface of the right keyboard.

[0011] Furthermore, rubber pads are provided at both ends of the bottom front and rear sides of the left and right keyboards.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting a three-section hinge structure between the left and right keyboards, the keyboard can be smoothly folded in half. After folding, the overall volume is significantly reduced, making it easy to carry or store in a backpack or handbag. This effectively solves the problem of inconvenience in moving and using traditional mechanical keyboards due to their large size and non-foldability. In addition, with the inward pressing force of the slider under the action of the elastic element, the left and right keyboards fit tightly when unfolded and assembled, improving the overall structural rigidity and ensuring no shaking or looseness when typing, thus guaranteeing input stability.

[0013] 2. By setting up a press-type locking structure consisting of a press lever, a locking block, a locking slot, and a second elastic element, the left and right keyboard units are rigidly locked in use. Under normal conditions, the locking block automatically inserts into the locking slot under the action of elastic force, preventing accidental separation caused by external impact or wrist rest during typing. To unlock, simply press down the lever to complete the unlocking. The operation is simple and the response is fast, taking into account both safety and convenience. Attached Figure Description

Detailed Implementation

[0022] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0023] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 A foldable multi-mode mechanical keyboard includes a left keyboard 1 and a right keyboard 2, which can be used separately or in combination. When combined, the left keyboard 1 and right keyboard 2 form a complete full-size keyboard. It supports three communication modes: wireless Bluetooth, wired USB, and 2.4GHz wireless reception. Users can freely choose the connection method via a mode switch key or system settings. Both the left keyboard 1 and right keyboard 2 have a standard keycap array 3 arranged regularly on their surfaces. Guide grooves 4 are provided on the front and back sides of the interior of both the left keyboard 1 and right keyboard 2. Slider 5 is slidably installed inside the guide grooves 4, and three first elastic elements connect the slider 5 to the inner wall of the guide groove 4. Component 6 provides reset elasticity and structural cushioning. Three horizontally arranged and interconnected hinges 7 are provided between the sliders 5 of the left keyboard 1 and the right keyboard 2, forming a three-segment linked folding structure. The three-hinge layout effectively disperses stress and maintains structural stability in both unfolded and folded states, preventing structural deformation or fatigue fracture due to single-point stress, thus improving overall durability. The surface of the left keyboard 1 is equipped with signal indicator lights 8 to display real-time information such as current connection mode, battery status, Caps Lock, and Num Lock, enhancing the human-computer interaction experience. Rotary pivots 16 are rotatably installed at the rear corners of the bottom surfaces of both the left keyboard 1 and the right keyboard 2. A support block 17 is provided on the pivot 16. The support block 17 can rotate synchronously with the pivot 16 to achieve two states: folded and unfolded. Its bottom surface contacts the support surface, thereby raising the rear of the keyboard to form an ergonomic tilt angle, which helps reduce wrist fatigue and improve typing posture. When not in use, the support block 17 can be flipped upwards and stored on the bottom of the keyboard to keep the overall surface flat and prevent damage to the exposed structure during transportation. LED light strips 18 are embedded in the front surfaces of the left keyboard 1 and the right keyboard 2. The LED light strips 18 serve as ambient lighting to enhance visual appeal and can also integrate status indicator functions. The left side of the bottom surface of the left keyboard 1... A first magnet 19 is provided, and a second magnet 20 is provided on the right side of the bottom surface of the right keyboard 2. The two magnets have opposite polarities and form a magnetic attraction relationship. When the left and right keyboards 2 are close to each other in the folded or unfolded state, the two magnets generate magnetic force to guide the two units to automatically align and keep them in a close fit. This can effectively prevent the keyboard from being accidentally unfolded and improve the safety of carrying it. Rubber pads 21 are provided at both the front and rear ends of the bottom surface of the left keyboard 1 and the right keyboard 2 to form a multi-point support layout, ensuring that the keyboard is placed stably and preventing it from slipping during typing. At the same time, the rubber material can effectively absorb the vibration of the keystrokes, reduce the impact noise on the desktop, and protect the desktop from scratches.

[0024] When the keyboard needs to be folded for storage, the user applies inward force to fold the left and right keyboard units 2 together. The three sets of hinges 7 bend and rotate simultaneously, while the slider 5 slides outward along the guide groove 4, compressing the first elastic element 6 to store elastic potential energy. During this process, the overall width of the keyboard is significantly reduced, forming a compact folded shape that is easy to carry and store. When unfolded for use, the user pulls the left and right keyboard units 2 outward, and the hinges 7 gradually return to the coplanar unfolded state. During this process, the potential energy stored in the first elastic element 6 is released, pushing the slider 5 to retract into the guide groove 4, thereby applying a continuous inward pressing force to the left and right keyboard units 2, ensuring that the two units fit tightly after being assembled, eliminating lateral gaps, and improving the consistency of typing feel and the overall rigidity of the structure.

[0025] Example 2: Based on Example 1, please refer to... Figures 4-6 The left keyboard 1 has a horizontally oriented groove 9 running front to back. A vertically slidable push rod 10 is mounted inside the groove 9. One end of the push rod 10 extends rearward from the groove 9 and protrudes from the surface of the left keyboard 1, with a toggle block 15 fixed to its end for manual operation. Both ends of the push rod 10 are fixed with locking blocks 11. The right keyboard 2 has locking slots 12 on both its front and rear sides that match the locking blocks 11. When the left and right keyboards 2 are unfolded and closed, the locking blocks 11... It can be inserted upward into the slot 12 to form a rigid mechanical lock, realizing a reliable connection and positioning between the two keyboards. Two guide rods 13 are fixedly connected at even intervals along the axial direction on the pressing rod 10. The left keyboard 1 has a guide hole that slides with the guide rod 13. A second elastic element 14 is sleeved on the guide rod 13. The upper and lower ends of the second elastic element 14 are fixedly connected to the pressing rod 10 and the left keyboard 1 respectively, thereby providing an upward reset force for the pressing rod 10 under normal conditions.

[0026] When the keyboard is unfolded and in use, as the left and right keyboard units 2 are unfolded and tightly joined together via the three-section hinge 7, the pressing lever 10 automatically moves upward under the elastic restoring force of the second elastic element 14, causing its upper locking block 11 to move upward synchronously and accurately embed into the corresponding locking slot 12 on the right keyboard 2 side, achieving physical locking. This locking state can effectively prevent the left and right keyboards 2 from sliding laterally, misaligning, or accidentally separating during typing or external impact, significantly improving the overall structural rigidity and operational stability. When folding for storage is required, the user moves the lever downward. 15. Drive the pressing rod 10 to overcome the elastic force of the second elastic element 14 and move vertically downward along the slide groove 9, causing the locking block 11 to disengage from the slot 12 and complete the unlocking action. During this process, the guide rod 13 slides synchronously along the guide hole, which plays a guiding and anti-deviation role, ensuring that the unlocking action is smooth and without jamming. At the same time, the second elastic element 14 is compressed and stored to provide power for subsequent reset. After unlocking, the user can apply inward force to fold the left and right keyboard 2 units. The three-section hinge 7, together with the slider 5, slides in the guide groove 4 to achieve smooth folding and finally enter the compact storage state.
