Description

Technical Field

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

[0002] Mechanical switches are a common type of key found on keyboards and are widely used in computers and various terminal devices. Operators can use mechanical switches to input various commands or data into the computer, thereby controlling the computer's operation.

[0003] Currently, the key switches used in computer devices 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 certain inconveniences for 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 main keycap, a switch face shell, a switch bottom shell, and a side axis assembly. The switch bottom shell is snapped and fixed to the bottom of the switch face shell. The main keycap is disposed on the top of the switch face shell. The side axis assembly is disposed on one side of the main keycap and located on the top of the switch face shell. The side axis assembly includes a fixed post fixedly connected to the switch face shell. A spring post is slidably connected inside the fixed post. A transmission frame is fixedly connected to the top of the spring post. A side keycap is fixedly connected to the top of the transmission frame. A pair of connecting posts are fixedly connected to the bottom of the transmission frame. Conductive silicone is fixedly connected to the bottom end of the connecting posts. Through holes are formed on the switch face shell and the switch bottom shell at the corresponding connecting posts. During the pressing of the side keycap, one of the conductive silicone pieces passes through the through hole and contacts the PCB board to conduct electrical signals.

[0007] Preferably, a side return spring is sleeved between the transmission frame and the shaft shell, located outside the spring column.

[0008] Preferably, a mounting cavity is formed between the front shell and the back shell of the switch body, and a spindle core is provided in the mounting cavity. The front shell of the switch body has a mounting hole for the spindle core to pass through. The spindle core is slidably installed in the mounting hole. The bottom of the main keycap is provided with a slot for engaging and fixing with the spindle core. A spindle core spring post is fixedly connected to the bottom of the spindle core. A return spring is sleeved between the spindle core and the back shell of the switch body, located outside the spindle core spring post.

[0009] Preferably, a pair of limiting blocks are fixedly connected to the bottom end of the outer wall of the shaft core, and a limiting groove is formed in the mounting hole along the axial direction, with the limiting blocks placed in the limiting groove.

[0010] Preferably, a shaft core contact is fixedly connected to the bottom end of the outer wall of the shaft core. A stationary plate and a moving plate are installed inside the bottom shell of the shaft body for cooperation. In the initial state of the shaft core, the shaft core contact abuts against the moving plate, causing the moving plate to deform. After the shaft core is pressed to a certain distance, the shaft core contact separates from the moving plate, causing the moving plate to reset and contact the stationary plate, so as to conduct electrical signals to the PCB board.

[0011] Preferably, the connecting post passes through the through hole in the shaft shell and is fixedly connected with a connecting post buckle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the setting of a side shaft component, 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 original switch structure that 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, offers a new key method for the key switches of currently common keyboard devices, and provides users with an experience of two different pressing sensations.

Detailed Implementation

[0018] 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.

[0019] Example: Please refer to Figures 1-3 This embodiment provides a key switch assembly capable of triggering two commands, including a main keycap 100, a switch face shell 101, a switch bottom shell 102, and a side axis assembly 200. The switch bottom shell 102 is snapped and fixed to the bottom of the switch face shell 101, the main keycap 100 is disposed on the top of the switch face shell 101, and the side axis assembly 200 is disposed on one side of the main keycap 100 and located on the top of the switch face shell 101.

[0020] The side axis assembly 200 includes a fixed post 205 fixedly connected to the switch housing 101. A spring post 204 is slidably connected inside the fixed post 205. A transmission frame is fixedly connected to the top of the spring post 204. A side keycap 201 is fixedly connected to the top of the transmission frame. A pair of connecting posts 207 are fixedly connected to the bottom of the transmission frame. A conductive silicone 206 is fixedly connected to the bottom of the connecting posts 207. Through holes are opened on the switch housing 101 and the switch bottom housing 102 at the corresponding positions of the connecting posts 207. During the pressing down of the side keycap 201, one of the conductive silicone 206 passes through the through hole and contacts the PCB of the keyboard to conduct electrical signals.

[0021] A mounting cavity is formed between the switch face shell 101 and the switch bottom shell 102. A switch core 104 is provided in the mounting cavity. A mounting hole is provided on the switch face shell 101 for the switch core 104 to pass through. The switch core 104 is slidably installed in the mounting hole. A slot 103 is provided at the bottom of the main keycap 100 to engage and fix with the switch core 104. A switch core contact 109 is also fixedly connected to the bottom end of the outer wall of the switch core 104. A stationary plate 106 and a moving plate 105 are installed inside the switch bottom shell 102. In the initial state of the switch core 104, the switch core contact 109 abuts against the moving plate 105, causing the moving plate 105 to deform. After the switch core 104 is pressed to a certain distance, the switch core contact 109 separates from the moving plate 105, causing the moving plate 105 to reset and contact the stationary plate 106, thus transmitting electrical signals to the PCB board.

[0022] Specifically, during use, pressing the side keycap 201 in the side axis assembly 200 causes the connecting post 207 to descend along with the side keycap 201, bringing the conductive silicone 206 into contact with the PCB board to conduct electrical signals and trigger one instruction. Pressing the main keycap 100 then causes the switch core 104 to press down, separating the switch core contact 109 from the moving piece 105, allowing the moving piece 105 to reset and contact the stationary piece 106, transmitting electrical signals to the PCB board and triggering another instruction. By adjusting the side axis assembly 200 to accommodate another up-and-down pressing method while maintaining the same main body of the key switch, a new operating method is added to the switch structure that originally only had a single pressing instruction. This allows the key switch to trigger two instructions, providing new possibilities for keyboard layout. For example, it allows for the design of keyboards that save desktop space and reduces design costs. It also provides a new keying method for commonly used keyboards, offering users a unique two-key pressing experience.

[0023] In this embodiment, as Figure 2 As shown, a side return spring 203 is sleeved between the transmission frame and the shaft housing 101 and outside the spring post 204. The spring post 204 and the side return spring 203 are used to reset the side keycap 201 so that the side keycap 201 can be pressed again next time.

[0024] In this embodiment, as Figure 3 As shown, a core spring post 108 is fixedly connected to the bottom of the core 104. A return spring 107 is sleeved between the core 104 and the bottom shell 102 of the switch body and outside the core spring post 108. The core spring post 108 and the return spring 107 are provided to facilitate the next press of the main keycap 100.

[0025] In this embodiment, a pair of limiting blocks are fixedly connected to the bottom of the outer wall of the shaft core 104. A limiting groove is opened along the axial direction in the mounting hole, and the limiting blocks are placed in the limiting groove. The limiting blocks and the limiting blocks play a limiting and guiding role in the mounting hole, preventing the shaft core 104 from deflecting.

[0026] In this embodiment, as Figure 3 As shown, the connecting post 207 passes through the through hole of the switch housing 101 and is fixedly connected with the connecting post buckle 202. The buckle 202 allows the connecting post 207 to pass through the through hole of the switch housing 101 for better fixation. When the side keycap 201 is reset by the side reset spring 203, it is limited by the buckle 202 and fixed in the reset position. The descent process of the side keycap 201 is deeper than that of the main keycap 100, and the side keycap 201 can descend asynchronously with the main keycap 100 to realize two key operation modes.

[0027] Working principle: In use, pressing the side keycap 201 in the side axis assembly 200 causes the connecting post 207 to descend along with the side keycap 201, bringing the conductive silicone 206 into contact with the PCB board to conduct electrical signals and trigger one instruction. Pressing the main keycap 100 causes the switch core 104 to press down, separating the switch core contact 109 from the moving piece 105, allowing the moving piece 105 to reset and contact the stationary piece 106, conducting electrical signals to the PCB board and triggering another instruction. By setting up the side axis assembly 200, with the main parts of the key switch being the same, the side part of the switch is adjusted to accommodate another up-and-down pressing method. This adds another operation mode to the switch structure that originally only had a single pressing instruction. Since the key switch can trigger two instructions, it provides new possibilities for the key layout of keyboard devices and provides users with an experience of two different pressing sensations.

[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.
