Description

TECHNICAL FIELD

[0001] The utility model relates to the keyboard key field especially relates to a special-shaped key cap, special-shaped key cap and keyboard. BACKGROUND

[0002] In the prior art, the traditional single-shears structure keyboard when processing special-shaped or large size character key, often exist structural strength is insufficient, touch feeling is uneven etc. These defects not only influence the user's use experience, also limit the keyboard design diversity and innovativeness. In addition, due to the structural limitation, the reinforcement of special-shaped key cap is usually difficult to realize, resulting in the overall performance of the product decline. UTILITY MODEL CONTENTS

[0003] The utility model aims at providing a special-shaped key cap and the key module and keyboard using the special-shaped key cap with higher structural strength, better touch feeling and beautiful appearance.

[0004] Technical scheme: the special-shaped key cap of the utility model, including the key cap female die and key cap male die of two-shot molding, the key cap female die is special-shaped key cap body, and the key cap male die is the reinforcing structure that surrounds the outside of special-shaped key cap body.

[0005] Further, the key cap male die material carries out plastic reinforcing.

[0006] Further, the key cap male die adopts polycarbonate material and adds glass fiber reinforcing.

[0007] Further, the key cap male die adopts nylon material and adds glass fiber reinforcing.

[0008] Further, the key cap female die bottom is equipped with a plurality of connecting pieces for making the key cap with the assembly of other components of key module.

[0009] The utility model of a kind of key module, key adopts the special-shaped key cap structure as described above.

[0010] Further, the key module adopts single-shears, without balance bar structure.

[0011] The utility model of a kind of keyboard, adopts the key module as described above.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: (1) The irregular keycap of the present invention adopts a double injection molding male mold and female mold structure. Through two injection molding processes, the male mold (1 injection) structure focuses on structural reinforcement, which not only makes the keycap have excellent mechanical properties, but also effectively resists deformation and wear under long-term use. The female mold (2 injection) focuses on appearance and touch, using easy-to-form and beautiful materials to ensure the overall aesthetics of the keyboard and user experience, while ensuring the aesthetics and functionality of the product; (2) The key module of the present invention adopts the above-mentioned irregular keycap, which can achieve a stable structure and uniform touch without the need for an additional balance bar.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0018] Example 1

[0019] like Figures 1-3 As shown, this embodiment provides a non-standard keycap including a keycap female mold 1 and a keycap male mold 2, both formed by double-shot molding. The keycap female mold 1 is the body of the non-standard keycap. The bottom of the keycap female mold 1 has several connectors for assembling the keycap with other components of the key module (such as scissor-switch leads). The material of the keycap female mold 1 can be easily molded while also meeting aesthetic requirements. The keycap male mold 2 is a reinforcing structure wrapped around the outside of the non-standard keycap body, and its material is reinforced with plastic. In this embodiment, the appearance and structure can be manufactured independently, avoiding conflicting molding methods. This optimizes aesthetic requirements and prevents appearance problems caused by uneven thickness. Simultaneously, the structural strength is more stable, the corners of the non-standard structure feel better, and the tightness of the bond is better compared to adhesive bonding using double-shot molding.

[0020] In some embodiments, the keycap mold 2 is made of polycarbonate material and reinforced with glass fiber.

[0021] In some embodiments, the keycap mold 2 is made of nylon material and reinforced with glass fiber.

[0022] Example 2

[0023] The key module provided in the embodiment adopts the special-shaped key cap mentioned in any one of embodiments 1-2. Since the special-shaped key cap has good structural strength, the key module can adopt a single scissors without a balance bar structure.

[0024] Embodiment 3

[0025] The keyboard provided in the embodiment adopts the key module mentioned in embodiment 2.
