Description

Technical Field

[0001] The utility model relates to the technical field of keyboards, and in particular discloses a key cap structure with functions and a keyboard. Background Art

[0002] A keyboard is a device used to input commands and data to operate a computer. It also refers to a set of function keys arranged systematically to operate a machine or device (such as a typewriter or computer keyboard). The keyboard is the most commonly used and primary input device, allowing users to enter English letters, Chinese characters, numbers, punctuation marks, and more into a computer, thereby issuing commands and inputting data.

[0003] Traditional keyboards utilize a "keycap + key switch + midplate + key base" structure. The keycap is the visible part of the keyboard, the part that the user directly interacts with for inputting characters or executing commands. The keycap design can affect the feel and comfort of the keys. The key switch is the core component of the keyboard, located beneath the keycap. It senses the user's key presses and converts these movements into electronic signals for processing by the computer. The type and quality of the key switch directly impacts the keyboard's durability and user experience. The midplate, also known as the positioning plate, sits beneath the key switches. It provides stable support and transmits the key switch's motion to the keyboard's circuitry. The material and design of the midplate also impact the keyboard's overall performance and feel. The key base's primary function is to provide stability and support. A keyboard's key base is a crucial component, located beneath each key and providing stable support for the keycap. The design and material of the key base have a significant impact on the keyboard's overall performance and user experience. The key base not only supports the keycap but also interacts with other keyboard components (such as the support structure and magnetic components) to enable key movement and retraction. This structural design enables the keyboard to effectively convert user input into instructions that the computer can understand, while ensuring the accuracy and reliability of the input.

[0004] However, existing keyboards have the following defects:

[0005] 1. The push button switch requires a separate component to be installed on the mid-board, which is costly. In addition, due to the high installation precision requirements, poor installation may occur, and the production cost is also relatively high.

[0006] 2. Existing keyboards require separate key switches. A standard keyboard requires 108 key switches, which increases material costs accordingly.

[0007] Therefore, the above-mentioned defects of the existing keyboards are technical problems that need to be solved urgently. Utility Model Content

[0008] The utility model provides a key cap structure with functions and a keyboard, aiming to solve at least one defect existing in the above-mentioned existing keyboards.

[0009] One aspect of the present invention relates to a functional keycap structure, comprising a keycap, a magnet, a spring, a positioning plate and a PCBA. The magnet is embedded in the keycap, located between the keycap and the positioning plate, and the keycap and the positioning plate are buckled together. The PCBA is correspondingly arranged below the positioning plate and generates induction with the magnet.

[0010] Furthermore, a sliding groove is provided on the positioning plate, and a sliding block matching the sliding groove is correspondingly provided on the keycap, and the positioning plate and the keycap are slidably connected via the sliding groove and the sliding block.

[0011] Furthermore, a buckle is provided at the bottom of the keycap, and a corresponding position that cooperates with the buckle is provided at the top of the positioning plate.

[0012] Furthermore, a mounting portion is extended along the center of the bottom of the keycap, and the magnet is embedded in the mounting portion.

[0013] Furthermore, the magnet is in the shape of a bar-shaped rectangular parallelepiped.

[0014] Furthermore, the spring is cylindrical in shape.

[0015] Furthermore, a sensing through hole corresponding to the position of the mounting portion is provided on the positioning plate.

[0016] Another aspect of the present invention relates to a keyboard with functions, including the above-mentioned keycap structure with functions, a plurality of keycaps are buckled on a positioning plate, and each keycap is correspondingly inlaid with a magnet.

[0017] Furthermore, a Hall switch corresponding to each magnet is provided on the PCBA.

[0018] Furthermore, the positioning plate and the PCBA are fixedly connected by screws.

[0019] The beneficial effects achieved by the utility model are:

[0020] This utility model provides a functional keycap structure and keyboard, comprising a keycap, a magnet, a spring, a positioning plate, and a PCBA. The magnet is embedded within the keycap and positioned between the keycap and the positioning plate, and the keycap and the positioning plate interlock with each other. The PCBA is positioned below the positioning plate and generates induction with the magnet. The functional keycap structure and keyboard provided by this utility model are simple in structure and cost-effective. They do not require separate key switches, reducing material costs.

The keyboard provided in this embodiment has a spring 30 placed in the spring placement position of the positioning plate 40, and then the plurality of keycaps 10 inlaid with magnets 20 are correspondingly buckled into the positioning plate 40 with the spring 30 placed thereon, and finally the PCBA50 is fixed to the positioning plate 40 by screws 60. The keyboard is completed, easy to assemble, and reduces the difficulty of assembly, thereby reducing the manufacturing cost accordingly.

[0038] like Figures 8 to 11 As shown, the keycap structure and keyboard with functions provided in this embodiment have the following working principles:

[0039] When assembling the keyboard, first place the spring 30 in the spring placement position of the positioning plate 40, then buckle the multiple keycaps 10 embedded with magnets 20 into the positioning plate 40 where the spring 30 is placed, and finally fix the PCBA 50 to the positioning plate 40 with screws 60. The keyboard is completed, easy to assemble, reducing the difficulty of assembly and correspondingly reducing the manufacturing cost.

[0040] When the keyboard is in use, when the keycap 10 is pressed downward, the magnet 20 is prompted to sense the corresponding Hall switch on the PCBA 50, thereby generating the corresponding function.

[0041] Compared to existing technologies, the functional keycap structure and keyboard provided in this embodiment utilize keycaps, magnets, springs, a positioning plate, and a PCBA. The magnets are embedded within the keycaps and positioned between them and the positioning plate, which engage with them. The PCBA is positioned below the positioning plate and generates induction with the magnets. The functional keycap structure and keyboard provided in this embodiment offer a simple and cost-effective structure. They eliminate the need for separate key switches, reducing material costs.
