Abstract
Description
Technical Field
[0001] This utility model relates to the field of key shells, specifically a high-strength keyboard key shell. Background Technology
[0002] Keyboard keys are the components that users directly contact. They are responsible for transmitting the user's typing actions to the key switches, thereby triggering the corresponding input signals. The function of the keys is to convert the user's typing actions into electrical signals that the electronic device can recognize, enabling operations such as character input and function execution.
[0003] Existing keyboard keycaps have the following drawbacks: Some keycaps are made of high-hardness plastic, such as untreated ABS plastic, resulting in a stiff feel and lack of tactile feedback when typing, which can easily lead to finger fatigue after prolonged use. Secondly, some keyboard keycaps have smooth surfaces and lack anti-slip design, making it easy for keycaps to slide under the user's fingers during rapid typing or when hands are sweaty, affecting typing accuracy and speed. Furthermore, due to their overly simple design, keycaps lack sufficient support structure. Under frequent use or forceful typing, keycaps are prone to deformation or damage, leading to a poor key feel or even failure to trigger input signals properly. Utility Model Content
[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a high-strength keyboard key shell, which can effectively solve the technical problems of poor tactile feel, easy slippage and low structural strength of existing keyboard key shells.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-strength keyboard key shell, including keycaps, the bottom of which is provided with an outwardly opening mounting cavity, a rubber pad is adhered to the surface of the keycap, a positioning round rod perpendicular to the inner wall of the keycap is provided inside the mounting cavity, a plurality of connecting plates are provided on the side of the positioning round rod, and adjacent connecting plates are symmetrically arranged, and a square frame perpendicular to the inner wall of the keycap is provided inside the mounting cavity, the square frame and the adjacent connecting plates forming a triangular structure.
[0006] Furthermore, a reinforcing plate is bonded to the inner wall of the keycap, and the thickness of the reinforcing plate is greater than the thickness of the keycap.
[0007] Furthermore, an elastic sponge block is adhered to the inner wall of the keycap, and the elastic sponge block is square in shape.
[0008] Furthermore, the keycap is trapezoidal in shape and is made of ABS plastic or PBT plastic.
[0009] Furthermore, the surface of the rubber pad is printed with letter patterns.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a high-strength keyboard key shell with an outward-facing mounting cavity at the bottom of the keycap. Inside the mounting cavity, a positioning round rod and a square frame are set, forming a triangular structure through a connecting plate. This significantly enhances the structural strength and stability of the key shell, effectively preventing deformation or damage to the key during high-frequency use, extending the service life of the key, and improving the tactile feel and anti-slip performance of the key by attaching a rubber pad to the surface of the keycap.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] The following is combined Figure 1 and Figure 2 A detailed description of this utility model is provided below:
[0017] A high-strength keyboard key shell includes a keycap 1. The bottom of the keycap 1 has an outward-facing mounting cavity. A rubber pad 2 is adhered to the surface of the keycap 1. A positioning rod 3, perpendicular to the inner wall of the keycap 1, is disposed inside the mounting cavity. Several connecting plates 4 are disposed on the sides of the positioning rod 3, symmetrically arranged between adjacent connecting plates 4. A square frame 5, perpendicular to the inner wall of the keycap 1, is disposed inside the mounting cavity. The square frame 5 and the adjacent connecting plates 4 form a triangular structure. A reinforcing plate 7, with a thickness greater than that of the keycap 1, is adhered to the inner wall of the keycap 1. A spring-loaded... The keycap 1 is trapezoidal and made of ABS plastic. The surface of the rubber pad 2 is printed with letter patterns. The reinforcing plate 7 further improves the pressure resistance and rigidity of the key shell, ensuring the stability of the key when subjected to large external forces. At the same time, the addition of the elastic sponge block 6 effectively buffers the vibration and noise when the key is pressed, improving the comfort of using the key. The trapezoidal design of the keycap 1 conforms to the ergonomic principle, better fits the finger pressing habits, and reduces fatigue caused by long-term use. The use of ABS plastic ensures the high strength and durability of the key shell.
[0018] This embodiment provides a high-strength keyboard key shell with an outward-facing mounting cavity at the bottom of the keycap 1. Inside the mounting cavity, a positioning round rod 3 and a square frame 5 are provided, forming a triangular structure through a connecting plate 4. This significantly enhances the structural strength and stability of the key shell, effectively preventing deformation or damage to the key during high-frequency use, extending the key's lifespan. Furthermore, by attaching a rubber pad 2 to the surface of the keycap 1, the tactile feel and anti-slip performance of the key are improved.
