Description

Technical Field

[0001] The present application relates to the field of buttons, and in particular to a scissor-type ultra-low button module. Background Art

[0002] In the design and manufacture of modern electronic devices, especially portable electronic devices such as laptops, tablets and ultra-thin keyboards, the pursuit of lightness, thinness and compactness has always been the mainstream trend. The increasing user demand for portability and comfort has promoted the development of ultra-thin design technology.

[0003] Existing technologies have not been able to meet the needs of the above-mentioned technological developments. Specifically, traditional mechanical keys provide good feedback and durability, but their design is often relatively thick and heavy, which is not conducive to use in thin and light devices. This design limits the overall portability and lightness of the device. Although membrane key modules are thinner and lighter than mechanical keys, they are often inferior to mechanical keys in terms of tactile feedback and typing experience. In addition, the durability and reliability of membrane keys are also generally lower than mechanical keys. When trying to make thinner electronic devices, the design of existing key modules often cannot effectively utilize limited space, resulting in restrictions on the design of the device and failing to meet the requirements of both thinness and high performance at the same time.

[0004] In summary, developing an ultra-short key module is of great significance to the art. Utility Model Content

[0005] The purpose of the present application is to overcome at least one of the deficiencies of the prior art and to provide a scissor-type ultra-low key module that can better meet the market demand for thinner and more portable devices.

[0006] To achieve the above-mentioned purpose, the present application discloses a scissor-type ultra-low button module, comprising a bracket, two wing frames symmetrically hinged on the bracket, a tension spring connecting the two wing frames, and an elastic trigger component installed in the bracket, wherein the two wing frames have a free rotation angle upward around the connection position, and under normal conditions, the two wing frames are pulled up by the tension spring; the elastic trigger component comprises a fixed seat, a movable part inserted into the fixed seat, the movable part can have an automatic stroke in the vertical direction in the fixed seat, the fixed seat is installed with a reset spring and a spring-type switch through a reserved space, the movable part cooperates with the reset spring and the spring-type switch at the same time, a guide block cooperating with the spring-type switch is provided under the movable part, when the movable part moves downward, the guide block pushes the spring-type switch to realize switch triggering, and the reset spring provides an upward reset elastic force to the movable part.

[0007] Furthermore, the elastic trigger assembly has a reserved escape position for the tension spring.

[0008] Furthermore, the bracket and the elastic trigger assembly are mounted on a PCB board, and the PCB board has a circuit connected to and matched with the spring-type switch.

[0009] Furthermore, the fixing seat is reserved with two empty spaces, which are respectively installed with a reset spring and a spring-type switch, so that the reset spring and the spring-type switch are arranged at the same level, further reducing the height of the button module.

[0010] Furthermore, the spring-type switch includes a conductive fixed contact and a movable contact opposite to the fixed contact. The movable contact is separated from the fixed contact under normal conditions. The movable contact moves horizontally under the push of the movable part to achieve contact and conduction between the movable contact and the fixed contact.

[0011] Compared with the prior art, the present application has at least one of the following beneficial effects:

[0012] 1. Improved key responsiveness and accuracy: The combination of two wing frames and tension springs achieves fast key response and high-precision triggering. This design enables each press of the user to accurately trigger the corresponding command, thereby improving typing and operating efficiency and comfort.

[0013] 2. Enhanced durability of the key: The design of the elastic trigger component, including the reasonable combination of the fixed seat, movable parts, reset spring and spring switch, not only ensures the stability and reliability of the key, but also provides upward reset elastic force for the movable parts through the reset spring, thereby enhancing the durability of the key and the stability of long-term use, and providing a one- or two-stage pressing feel.

[0014] 3. Optimized space utilization and module thickness: The design of the entire module fully considers the effective use of space, especially the reserved tension spring avoidance position, as well as the compact layout of the bracket and elastic trigger component, which not only makes the module thinner and lighter, but also realizes the ultra-low design of the module without sacrificing performance, adapting to the current trend of electronic equipment towards thinness and lightness.

[0027] Reference Figure 1-4 This embodiment discloses an exemplary structure for achieving the purpose of this application. This embodiment relates to a scissor-type ultra-low key module, whose structural design is intended to meet the requirements of modern electronic devices for light, efficient and highly responsive keys. The design of this key module fully considers the efficiency of space utilization, as well as the requirements of providing excellent user tactile experience and long-term durability.

[0028] In terms of structure, as shown in the figure, in this embodiment, it includes a bracket 1, a wing frame 2, a tension spring 3, an elastic trigger component 4 and a PCB board 5.

[0029] The bracket 1 is a basic structure, fixedly mounted on the PCB board 5, and symmetrically hinged with two wing frames 2. These wing frames 2 can rotate freely upward around the joint and are designed to rotate freely at a certain angle, that is, have a certain free rotation stroke to provide excellent key feedback and reset capabilities. The two wing frames 2 are connected by a tension spring 3 to ensure that when there is no external force, the two wing frames 2 can be automatically pulled up to the normal position to achieve rapid reset.

[0030] In this embodiment, the elastic trigger assembly 4 is installed inside the bracket 1, and includes a fixed seat 6, a movable member 7, a reset spring 8, and a spring-type switch 9. The movable member 7 can move vertically in the fixed seat 6, and interact with the spring-type switch 9 through the guide block provided below to trigger the switch. At the same time, the movable member 7 also cooperates with the reset spring 8, and the reset spring 8 provides the movable member 7 with a vertical reset force.

[0031] In this embodiment, in order to reduce the height of the button module, the fixing seat 6 is designed with two reserved spaces for installing the reset spring 8 and the spring switch 9. These components work together with the movable part 7 to provide a stable trigger and reset mechanism.

[0032] In this embodiment, the spring switch 9 includes a conductive fixed contact and a movable contact. The two contacts are separated when there is no pressing force. The movable contact is pushed by the movable member 7 to move horizontally, thereby contacting and conducting with the fixed contact to close the circuit.

[0033] It should be understood that both the moving contact piece and the fixed contact piece are electrically connected to the PCB board.

[0034] When the present embodiment is implemented, during operation, when the user presses the button, the movable member 7 moves downward, pushing the guide block and the movable contact of the spring-type switch 9, causing the movable contact to contact the fixed contact, thereby closing the circuit to transmit the signal. Once the button is released, the tension spring 3 causes the two wing frames to return to their initial positions, and at the same time, the reset spring 8 provides an upward reset elastic force to the movable member 7, causing the movable member 7 and its guide block to return to their initial positions, and the contacts of the spring-type switch 9 are separated, disconnecting the circuit.

[0035] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
