Description

Technical Field

[0001] This utility model relates to the field of keyboard button technology, specifically a key switch component capable of triggering two commands. Background Technology

[0002] A keyboard is a common input tool for electronic devices. A keyboard has several key switches. Pressing a key switch generates a sensing signal. A key switch generally includes a housing, a travel component, and a signal component. The travel component generates a linear reciprocating motion to trigger the signal component to generate a sensing signal.

[0003] Currently, the key switches used in keyboards on the market usually only provide a single up and down pressing method to trigger commands. Some keys and shortcut commands often require the user to move their hand a considerable distance to press them. This also causes some infrequently used keys to occupy the layout space of the keyboard device, causing some inconvenience to users with limited desktop space or who need to move frequently. Therefore, there is an urgent need to design a key switch component that can trigger two commands to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a key switch component that can trigger two types of commands. This aims to solve the problem that existing key switches typically only provide a single up-and-down pressing method to trigger commands, resulting in inconvenience in pressing multiple keys simultaneously for shortcut commands, and some less frequently used keys occupying keyboard layout space.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A key switch assembly capable of triggering two commands includes a switch base shell, a switch top shell, a main keycap, and side keycaps. The switch top shell is mounted on top of the switch base shell, and the main keycap and side keycap are mounted on top of the switch top shell. A mounting cavity is formed between the switch base shell and the switch top shell. A switch core is disposed within the mounting cavity. A magnet retaining ring is fixedly connected to the outer side of the switch core. A first magnet is embedded within the magnet retaining ring.

The shaft surface shell and the shaft bottom shell are fixed together by the locking block being aligned and locked into the locking groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting the main keycap and side keycaps, adjusts the side part of the key switch to accommodate another up-and-down pressing method while keeping the main part of the key switch the same. This adds another operation method to the switch structure that originally only had a single pressing command. Since the key switch can trigger two commands, it provides new possibilities for the key layout of keyboard devices.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-5 This embodiment provides a key switch assembly capable of triggering two commands, including a switch base shell 110, a switch face shell 120, a main keycap 140, and a side keycap 160. The switch face shell 120 is mounted on top of the switch base shell 110, and the main keycap 140 and the side keycap 160 are mounted on top of the switch face shell 120. A mounting cavity is formed between the switch base shell 110 and the switch face shell 120, and a switch core 130 is disposed within the mounting cavity. A magnetic retaining ring 132 is fixedly connected to the outer side of the switch core 130. The iron fixing ring 132 is embedded with a first magnet 133. The bottom of the side keycap 160 is fixedly connected to a pair of connecting posts 161. The bottom of the connecting posts 161 is fixedly connected to a second magnet 162. The keyboard PCB board also includes a Hall sensor 170 that is installed at the position corresponding to the first magnet 133 and the second magnet 162. In actual application, only one second magnet 162 needs to be installed on the two connecting posts 161, and only one Hall sensor 170 is installed on the keyboard PCB board.

[0023] This invention, by setting the main keycap 140 and the side keycap 160, adjusts the side part of the key switch to accommodate another up-and-down pressing method while keeping the main part of the key switch the same. This adds another operation method to the switch structure that originally only had a single pressing command. Since the key switch can trigger two commands, it provides new possibilities for the key layout of keyboard devices. At the same time, by using a non-contact triggering method with a first magnet 133, a second magnet 162 and a Hall sensor 170, the key is triggered through the Hall effect. It provides a customizable trigger stroke for the main part and the side part of the key switch and provides a more stable electrical triggering method. This is existing technology, and its specific working principle will not be elaborated here.

[0024] In this embodiment, a mounting post 141 is fixedly connected to the bottom of the main keycap 140. A first through hole 121 is provided on the shaft shell 120 for the mounting post 141 to pass through. A mounting cavity for accommodating the mounting post 141 is provided on the top of the shaft core 130. A plug block 131 is fixedly connected inside the mounting cavity. A plug groove 142 for the plug block 131 to be inserted is provided at the bottom of the mounting post 141. A shaft core spring post 135 is fixedly connected to the bottom of the shaft core 130. A main keycap return spring 1 is installed between the bottom of the shaft core 130 and the bottom end inside the shaft shell 110. 50. The main keycap return spring 150 is sleeved on the outside of the core spring post 135. When the main keycap 140 is installed with the core 130, the mounting post 141 is inserted into the mounting cavity of the core 130, and the plug block 131 is aligned and plugged into the plug slot 142, so that the main keycap 140 and the core 130 are connected and installed. When the main keycap 140 is pressed, it drives the core 130 to move synchronously. The core spring post 135 and the main keycap return spring 150 are used to reset the core 130 and the main keycap 140 so that the main keycap 140 can be pressed again next time.

[0025] In this embodiment, a pair of first limiting blocks 134 are symmetrically fixedly connected to the outer side of the bottom of the spindle core 130. The bottom of the spindle shell 120 and the sides of the first through hole 121 are symmetrically provided with first limiting grooves 122. The first limiting blocks 134 are slidably connected to the first limiting grooves 122. The first limiting blocks 134 and the first limiting grooves 122 play a limiting and guiding role for the spindle core 130, preventing the spindle core 130 from shifting position during movement, improving the stability of the movement of the spindle core 130, and at the same time playing a limiting role for the spindle core 130, ensuring that the spindle core 130 and the main keycap 140 are restricted to the return position when reset.

[0026] In this embodiment, the switch housing 120 is further provided with a second through hole 123 for the connecting post 161 to pass through. A second limiting block 163 is fixedly connected to the outer side of the connecting post 161. A second limiting groove 124 is provided at the bottom of the switch housing 120 and at the second through hole 123. The second limiting block 163 is slidably connected in the second limiting groove 124. A side keycap spring post 164 is also fixedly connected to the bottom of the side keycap 160. A third through hole 125 is also provided on the switch housing 120 for the side keycap spring post 164 to pass through. A side keycap return spring 165 is installed between the bottom of the side keycap 160 and the top of the switch housing 120. Five spring pillars 164 are set on the outside of the side keycap spring pillars 164. When the side keycap 160 is pressed, it moves in the second through hole 123 through the connecting pillar 161, and the side keycap spring pillars 164 move in the third through hole 125. This plays a limiting and guiding role for the side keycap 160, improving the stability of the movement of the side keycap 160. The side keycap spring pillars 164 and the side keycap return spring 165 are used to reset the side keycap 160 so that it can be used for the next press. At the same time, under the action of the second limiting block 163 and the second limiting groove 124, the side keycap 160 is limited to the return position when it is reset.

[0027] In this embodiment, a locking block is provided on the outer wall of the shaft bottom shell 110, and a locking groove corresponding to the position of the locking block is provided on the shaft surface shell 120. The shaft surface shell 120 and the shaft bottom shell 110 are fixed by locking the locking block into the locking groove, which is used for quick assembly connection of the shaft bottom shell 110 and the shaft surface shell 120.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
