Description

Technical Field

[0001] This utility model relates to the field of keyboards, and more particularly to a keyboard that facilitates key replacement. Background Technology

[0002] Keyboards, as essential input devices for computers and other electronic devices, are widely used in daily life and work. With increasing user demand for keyboard personalization, the need for key replacement is also growing. However, traditional keyboard keys are typically fixed to the keyboard base by welding or gluing, requiring the entire keyboard to be disassembled or specialized tools for key replacement, which is complex and can easily damage the keyboard structure. Existing snap-on keyboard designs allow for key replacement. However, existing snap-on keyboard designs have the following drawbacks;

[0003] 1. The snap-fit ​​structure is prone to loosening, causing the buttons to fall off during use;

[0004] 2. Replacing buttons requires special tools, making the operation inconvenient;

[0005] Based on this, we propose a keyboard that allows for easy key replacement. Utility Model Content

[0006] To address the technical problem of easy loosening of the snap-fit ​​structure, this utility model provides a keyboard that facilitates key replacement.

[0007] This utility model is achieved by the following technical solution: a keyboard that is easy to replace keys, including a keyboard body, the keyboard body including keyboard keys and a key removal and assembly mechanism; the key removal and assembly mechanism is installed on a base plate, a circuit board is installed on the base plate, and the circuit board is connected to the keyboard keys.

[0008] The button assembly / disassembly mechanism includes a fixed plate, a return spring connected to the inner side of the fixed plate, the return spring being connected between the fixed plate and the clamping plate, the clamping plate being made of metal; a movable base plate is fixedly connected to the bottom end of the clamping plate, the movable base plate being slidably connected to the slide groove, and a disassembly / assembly mother plate is fixedly connected to the outer side of the clamping plate, forming a clamping cavity between the two sets of opposing clamping plates.

[0009] When replacing keyboard keys, users simply need to gently expand the clamping plate outwards to separate the mother plate from the daughter plate, allowing the key to be removed from the clamping cavity. To install a new key, the daughter plate is inserted into the clamping cavity, and the two mother plates then engage with it for positioning. Two return springs automatically reset the clamping plate, ensuring a tight connection between the mother and daughter plates and guaranteeing key stability. The return springs and sliding groove design ensure a smooth and convenient key replacement process, enhancing the keyboard's user experience.

[0010] As a further optimization of this utility model, a chip switch is fixedly connected to the bottom of the keyboard keys, and the chip switch extends downwards with wire contacts that connect to the circuit board. Detachable sub-boards are installed on both sides of the bottom of the chip switch. The chip switch is installed below the keyboard keys, and pressing the keyboard keys actuates the chip switch to input commands.

[0011] As a further optimization of this utility model, a sliding groove is opened on the fixed plate. The sliding groove is a straight groove. A slider extends downward from the bottom end of the movable base plate and slides inside the sliding groove to guide the movable base plate to slide smoothly.

[0012] As a further optimization of this utility model, both the disassembly mother plate and the disassembly daughter plate are rectangular plates. In the installed state, the disassembly daughter plate is snapped into the inside of the two sets of disassembly mother plates.

[0013] As a further optimization of this utility model, the reset spring is a helical spring, which has high elasticity and durability, and can ensure the smooth movement of the clamping plate during the button replacement process.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model automatically resets the clamping plate using two sets of reset springs, ensuring a tight connection between the disassembly / reassembly mother plate and the disassembly / reassembly daughter plate, thus ensuring the stability of the keys. The design of the reset springs and slide grooves ensures a smooth and convenient key replacement process, improving the keyboard's user experience.

[0016] 2. This utility model enables quick and convenient replacement of keyboard keys by setting a key disassembly and assembly mechanism, without the need for special tools.

[0017] 3. This utility model adopts a rectangular plate design for the disassembly mother plate and the disassembly daughter plate to ensure the stability of the button connection and prevent the button from falling off during use. Attached Figure Description
