Description

Technical Field

[0001] This utility model relates to the field of keyboard switch technology, specifically a resistive slider keyboard switch. Background Technology

[0002] The keyboard is the most commonly used and primary input device. Through the keyboard, English letters, numbers, punctuation marks, etc., can be entered into the computer, thereby issuing commands and inputting data. The key switches are an important part of the keyboard, making it convenient for users to operate.

[0003] Most keyboard switches on the market currently have a single function, meaning that each key can only transmit one type of signal. Although magnetic switches are widely used, they are susceptible to electromagnetic interference, which leads to unstable signal transmission and affects the user experience. Therefore, the applicant has designed a resistive slider keyboard switch that can transmit multiple signals and has strong anti-interference capabilities 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 resistive slider keyboard switch, which aims to solve the problems of existing keyboard switches having limited functionality, each key only transmitting one signal, and being susceptible to electromagnetic interference, resulting in unstable signal transmission.

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

[0006] A resistive slider keyboard switch includes a bottom shell and a top shell disposed on top of the bottom shell. A receiving cavity is formed between the bottom shell and the top shell. A key is disposed in the receiving cavity. A through hole is provided on the top shell for part of the key to pass through. A spring is installed between the bottom of the key and the bottom shell. A resistive element is installed on the side wall of the key. A terminal is installed on the bottom shell at the position corresponding to the resistive element. Two terminals are provided and are in contact with the resistive element. The connecting end of the terminal penetrates the bottom shell and extends to the outside.

[0007] As a preferred embodiment of this utility model, a pair of resistor fixing posts are fixedly connected to the side wall of the handle, and the resistor is provided with a socket corresponding to the resistor fixing post. The resistor and the handle are positioned and installed by the resistor fixing post passing through the socket.

[0008] In a preferred embodiment of this utility model, the two terminals are respectively disposed on both sides of the resistor sheet.

[0009] As a preferred embodiment of this utility model, the bottom of the front shell is fixedly connected with a retaining block around all four sides, and the outer wall of the bottom shell is provided with a retaining groove corresponding to the position of the retaining block around all four sides. The front shell and the bottom shell are fixed together by the retaining block being inserted into the retaining groove.

[0010] As a preferred embodiment of this utility model, a fixed sleeve is fixedly connected to the bottom end of the inner shell, a plug-in post is fixedly connected to the bottom of the handle, the bottom end of the plug-in post is movably inserted into the inside of the fixed sleeve, and the spring is sleeved on the outside of the fixed sleeve and the plug-in post.

[0011] As a preferred embodiment of this utility model, both sides of the handle are vertically provided with slide rails, and the inner wall of the face shell is provided with a slide groove corresponding to the position of the slide rail. The handle and the face shell are slidably connected through the slide rails and the slide groove.

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

[0013] This invention uses a resistor sheet fixed to the handle, with two terminals contacting both sides of the resistor sheet. By pressing the handle up and down, the vertical distance between the two terminals and the resistor sheet is changed, resulting in a corresponding resistance value between the two terminals and transmitted to the keyboard PCB board. The keyboard PCB board converts the resistance value into a corresponding signal and transmits it to the keyboard MCU. The keyboard MCU can control various output signals based on the received signal, conveniently and quickly realizing multiple functions control with a single button. Compared with magnetic switches, resistive switches are free from external magnetic and electric field interference, have stronger anti-interference capabilities, and more stable signal transmission.

[0020] 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.

[0021] Example: Please refer to Figures 1-5 This embodiment provides a resistive sliding keyboard switch, including a bottom shell 1 and a top shell 2 disposed on the top of the bottom shell 1. A receiving cavity is formed between the bottom shell 1 and the top shell 2, and a handle 3 is disposed in the receiving cavity. A through hole is opened on the top shell 2 for part of the handle 3 to pass through. A spring 6 is installed between the bottom of the handle 3 and the bottom shell 1. A resistive sheet 4 is installed on the side wall of the handle 3. Two terminals 5 are installed on the bottom shell 1 at the positions corresponding to the resistive sheet 4 and are in contact with the resistive sheet 4. The two terminals 5 are respectively disposed on both sides of the resistive sheet 4. The connecting end of the terminal 5 passes through the bottom shell 1 and extends to the outside. The connecting end of the terminal 5 extending to the outside of the bottom shell 1 serves as a pin. Connected to the keyboard PCB board, during use, the resistor 4 is fixed to the key 3, and the two terminals 5 are in contact with the two sides of the resistor 4 respectively. By pressing the key 3 up and down, the vertical distance between the two terminals 5 and the resistor 4 is changed, so that the corresponding resistance value between the two pins of the two terminals 5 is transmitted to the keyboard PCB board. The keyboard PCB board converts the resistance value into a corresponding signal and transmits it to the keyboard MCU. The keyboard MCU can control various output signals according to the received signal, which can conveniently and quickly realize multiple functions control of one key. Compared with magnetic switches, resistive switches are free from external magnetic and electric field interference, have stronger anti-interference ability, and more stable signal transmission.

[0022] In this embodiment, as Figure 2 and Figure 3 As shown, a pair of resistor plate fixing posts 302 are fixedly connected to the side wall of the handle 3. The resistor plate 4 has corresponding insertion holes at the resistor plate fixing posts 302. The resistor plate 4 and the handle 3 are positioned and installed by the resistor plate fixing posts 302 passing through the insertion holes. When assembling the resistor plate 4 and the handle 3, the insertion holes on the resistor plate 4 are aligned and inserted into the resistor plate fixing posts 302 on the handle 3 to ensure the resistor plate position remains unchanged. To improve the fixing effect, the resistor plate 4 and the handle 3 can also be fixed with adhesive. In other embodiments, such as... Figure 5 As shown, an insert-type tight-fit connection can also be used. A pair of guide rails are provided on the outside of the handle 3. The resistor 4 is inserted between the pair of guide rails to achieve fixation. Only a stable assembly of the resistor 4 and the handle 3 is required. The resistor 4 is made of PCB material or plastic material, which has good conductivity and stability.

[0023] In this embodiment, as Figure 4 As shown, the terminals 5 extend to the outside of the bottom shell 1 as pin connection ends and have various forms. The connection ends of the two terminals 5 can be set flush or staggered to adapt to different keyboard PCB boards for connection.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the bottom of the front shell 2 is fixedly connected with retaining blocks 202 around all four sides, and the outer wall of the bottom shell 1 is provided with retaining slots 102 corresponding to the positions of the retaining blocks 202 around all four sides. The front shell 2 and the bottom shell 1 are fixedly connected by retaining blocks 202 being inserted into retaining slots 102. The retaining blocks 202 and retaining slots 102 facilitate the fixed assembly of the front shell 2 and the bottom shell 1.

[0025] In this embodiment, as Figure 2 and Figure 3 As shown, a fixed sleeve 101 is fixedly connected to the bottom of the inner shell 1, and a plug pin is fixedly connected to the bottom of the handle 3. The bottom end of the plug pin is movably inserted into the fixed sleeve 101. The spring 6 is sleeved on the outside of the fixed sleeve 101 and the plug pin. During the up and down movement of the handle 3, the plug pin moves inside the fixed sleeve 101, which serves to limit and guide the handle 3 on the one hand, and restrict the position of the spring 6 on the other hand. The spring 6 provides the force for the handle 3 to reset, ensuring that the handle 3 can quickly return to its original position after operation.

[0026] In this embodiment, as Figure 2 As shown, slide rails 301 are vertically arranged on both sides of the handle 3. A groove 201 corresponding to the position of the slide rail 301 is opened on the inner wall of the face shell 2. The groove 201 is designed to extend through the lower end to the lower end of the face shell 2, but not through the upper end of the face shell 2. The handle 3 and the face shell 2 are slidably connected by the slide rail 301 and the groove 201. The slide rail 301 and the groove 201 play a role in restricting and guiding the handle 3, ensuring that the handle 3 moves up and down smoothly and accurately, and preventing the handle 3 from detaching from the top of the face shell 2.

[0027] Working principle: During assembly, first install the two terminals 5 inside the bottom shell 1, then align and insert the socket on the resistor 4 with the resistor fixing post 302 on the key 3, install the resistor 4 onto the key 3, and then install the key 3 into the front shell 2, so that the key 3 and the front shell 2 are slidably connected through the slide rail 301 and the slide groove 201. Then, sleeve the spring 6 on the outside of the fixing sleeve 101, assemble the front shell 2 and the bottom shell 1, and connect and assemble the front shell 2 and the bottom shell 1 by inserting the plug on the key 3 into the fixing sleeve 101, so that the retaining block 202 is aligned and locked into the retaining slot 102, thus completing the keyboard opening. In the assembly of the switch, during use, the resistor 4 is fixed to the handle 3, and the two terminals 5 are in contact with the two sides of the resistor 4 respectively. By pressing the handle 3 up and down, the vertical distance between the two terminals 5 and the resistor 4 is changed, so that the corresponding resistance value between the two pins of the two terminals 5 is transmitted to the keyboard PCB board. The keyboard PCB board converts the resistance value into a corresponding signal and transmits it to the keyboard MCU. The keyboard MCU can control various output signals according to the received signal, which can conveniently and quickly realize multiple functions control of one button. Compared with magnetic switches, resistive switches are not affected by external magnetic and electric fields, have stronger anti-interference ability, and more stable signal transmission.

[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.
