Wherein the inclined base is provided with a top mounting matching surface and a bottom inclined surface, the mounting matching surface is used for bearing the micro-motion unit, and the bottom inclined surface and an external mounting plane form an assembly interface with an inclined angle. At least one positioning convex part is arranged at the bottom of the micro-motion unit; and a positioning groove body is correspondingly arranged on the mounting matching surface. Under the condition that a mold and a basic structure of the microswitch are not changed, through collaborative design of the inclined base and the pins with different lengths, asymmetric abrasion of lateral component force to internal components is reduced through axial coaxiality of the triggering direction and the driving force, the linearity and the operation smoothness of switch action are effectively improved, and the service life of the microswitch is prolonged. The service life is obviously prolonged; and the assembly reliability is enhanced.

Description

Technical Field

[0001] This application relates to the field of microswitches, and in particular to a tilted microswitch. Background Technology

[0002] In the field of existing electronic devices and input devices, microswitches, as a common triggering element, are widely used in devices such as mice and keyboards. Taking a mouse as an example, its left and right buttons typically employ a horizontally or vertically arranged microswitch structure. The pressing action of the button triggers the deformation of a metal spring inside the switch, thereby switching the circuit on or off. In traditional designs, the triggering direction of the microswitch is usually strictly aligned with the switch axis; for example, a vertically arranged microswitch requires the button to apply force in a vertical direction. However, in practical applications, it has been found that the movement trajectory of mouse buttons is not an ideal vertical motion. Because the button structure typically uses a single-sided hinge support, when the user presses the button, the button will form an arc-shaped trajectory or a diagonal straight line movement with the hinge point as the fulcrum, causing the direction of the driving force to deviate significantly from the triggering axis of the microswitch.

[0003] This mismatch between the motion trajectory and the triggering direction causes traditional microswitches to face multiple problems during long-term use. First, the non-axial driving force creates a lateral component force inside the switch, resulting in uneven friction between the metal spring and the contact, accelerating spring fatigue and contact oxidation, thus shortening the switch's electrical life. Second, the presence of lateral force increases the resistance during button operation, causing a stiff or stuck feel and affecting the smoothness of operation. Furthermore, due to differences in different users' pressing habits, the actual applied force angle may further deviate from the design axis, exacerbating the uncontrollability of the above problems. At its root, traditional designs are based on idealized vertical or horizontal motion assumptions and fail to fully consider the motion trajectory deviation caused by actual mechanical structures (such as hinged supports), resulting in insufficient coordination between the driving force and the switch triggering direction.

[0004] To address this technical bottleneck, developing a micro-switch structure that can adapt to actual motion trajectories is of great value. Utility Model Content

[0005] The purpose of this application is to overcome at least one deficiency of the prior art and to provide a tilted micro switch.

[0006] To achieve the above objectives, this application discloses an inclined micro switch, which includes a micro switch unit and an inclined base assembled therewith.

[0007] The inclined base has a top mounting surface and a bottom inclined surface. The mounting surface is used to support the micro-motion unit, and the bottom inclined surface forms an assembly interface with an inclined angle with the external mounting plane.

[0008] The micro-motion unit has at least one positioning protrusion at its bottom and a corresponding positioning groove on its mounting surface. The precise angular positioning of the micro-motion unit relative to the inclined base is achieved by the engagement of the protrusion and the groove, ensuring that the trigger axis and the direction of the external driving force form a preset coaxial relationship.

[0009] At least two conductive pins extend downward from the bottom of the micro-motion unit. The length of each pin is designed differently according to the tilt angle of the inclined base, so that when the pins are fully inserted into the slot inside the base, the height of the exposed part of each pin extending to the bottom inclined surface remains consistent.

[0010] Furthermore, the slot extends from the mounting mating surface to the bottom bevel.

[0011] Furthermore, the end face of the pin is geometrically machined to form a cut surface that matches the shape of the bottom bevel. When the pin is fully inserted, the bottom end of each pin is flush with the bottom bevel as a reference, so that the soldering point of each pin and the external circuit board is on the same plane, eliminating the height difference of the soldering surface caused by the tilted assembly, and avoiding poor electrical contact or mechanical stress concentration caused by uneven pin length during the soldering process.

[0012] Compared with the prior art, this application, without changing the mold and basic structure of the micro switch itself, achieves consistent exposed height of the pin ends and fits against the bottom slope by coordinating the design of the inclined base and the pins of different lengths. This ensures the coplanarity of the welding surface and the stability of electrical contact. At the same time, by making the triggering direction and driving force axially coaxial, the asymmetric wear of the lateral force on the internal components is reduced, effectively improving the linearity and smoothness of the switch action, significantly extending the service life and enhancing the assembly reliability.

[0024] See attached document Figures 1 to 4 In this embodiment, a tilted micro switch is provided. Its structural design aims to solve the problem of varying solder surface heights that may occur when traditional micro switches are assembled at an angle, while ensuring a precise coaxial relationship between the trigger axis and the direction of the external driving force. This micro switch is particularly suitable for devices such as mice that require frequent clicking, significantly improving user experience and product reliability.

[0025] Structurally, the micro-motion unit in this embodiment is the core functional component of the switch 1. It has at least one positioning protrusion 101 at its bottom, which is used to fit into the positioning groove 201 of the inclined base 2, thereby realizing the precise angular positioning of the micro-motion unit 1 on the inclined base 2.

[0026] In this embodiment, the inclined base 2 serves as a support structure. Its top is provided with a mounting mating surface 202 for supporting the micro-motion unit 1, and its bottom is designed as an inclined surface 203. The inclined surface 203 forms an inclined angle with the mounting plane inside the mouse. The specific angle can be adjusted according to the internal space of the mouse and design requirements.

[0027] Three pins 102 extend downward from the bottom of the micro-motion unit 1. The length of each pin 102 is designed differently according to the tilt angle of the inclined base 2. The cross-section of the pin 102 is rectangular, and the difference in their lengths is calculated geometrically to ensure that when the pin 102 is fully inserted into the slot 204 inside the inclined base 2, the exposed part of each pin 102 extending to the inclined surface of the bottom 203 is at the same height.

[0028] In the above structure, the slot 204 extends from the mounting mating surface 202 to the bottom slope 203, and its axial direction matches the tilt angle of the inclined base 2. The tilt of the slope 203 is compensated by the difference in the length of the pins 102, ensuring that the exposed height of the ends of each pin 102 is flush. The end face 103 of the pin 102 is geometrically machined to form a cut surface that matches the shape of the bottom slope 203. When the pins 102 are fully inserted into the slot, the bottom end of each pin 102 is flush with the bottom slope 203, so that the solder joints of each pin 102 and the internal circuit board of the mouse are on the same plane, thereby eliminating the height difference of the solder joints caused by the tilted assembly.

[0029] See attached document Figure 5 In mouse applications, microswitches need to withstand frequent clicks and long-term mechanical stress. The angled design not only optimizes welding reliability but also demonstrates significant advantages in force distribution and operational stability. The tilt angle of the angled base 2 allows the microswitch unit 1 to better distribute the stress generated by clicks after assembly. The click force is transmitted to the angled base 2 through the microswitch unit. The tilted design of the base 2 decomposes the vertical force into components along the inclined plane, thereby reducing local stress concentration. During mouse use, the trigger axis of the microswitch forms a precise coaxial relationship with the direction of the driving force applied by the user. This design ensures that each click accurately triggers the microswitch unit, avoiding inconsistent trigger strokes caused by force deviation.

[0030] It should be noted that the design and implementation methods of the internal contact structure and electrical performance parameters of the micro-motion unit are well-known to those skilled in the art and will not be elaborated upon here. For example, the selection of contact materials and surface treatment processes can refer to relevant standards, and the machining accuracy control of the slot can be achieved using conventional CNC machining technology. In summary, this embodiment solves the problem of welding surface height difference in inclined assembly through the cooperative design of the inclined base and the micro-motion unit, while ensuring the precise coaxial relationship between the trigger axis and the direction of the external driving force. This design is particularly suitable for devices such as mice that require frequent clicking operations, and can significantly improve product reliability and user experience.
