Description

Technical Field

[0001] The utility model relates to the field of micro switches, and in particular to an optical micro switch. Background Art

[0002] In the design of traditional optical switches, the optical switch column is an indispensable component. Although its existence realizes the switching function of the optical path, it also brings a series of challenges. The up and down movement of the button drives the corresponding movement of the optical switch column to adjust the optical path state of the light pair tube to achieve connection or blockage. However, this mechanism exposes some problems that cannot be ignored in practical applications.

[0003] The assembly process of the optical path switch column is relatively complicated and requires high-precision positioning and alignment, which increases the difficulty of production to a certain extent and affects the overall yield of the product. Any slight deviation may lead to inaccurate switching of the optical path and even affect the normal operation of the entire switch. In addition, the existence of the optical path switch column also increases the material cost and manufacturing cost of the product, which is undoubtedly a problem that needs to be solved for manufacturers who pursue maximum cost-effectiveness. Utility Model Content

[0004] In view of this, the utility model provides an optical microswitch, in which a spring has a lower extension plate extending downward, and a through hole is dug on the lower extension plate. When the button moves up and down, the position of the through hole on the spring can be changed, thereby realizing the overlap or misalignment of the through hole and the hole groove. The dynamic change of the overlap or misalignment directly leads to the connection or blocking of the optical path of the light to the tube, thereby realizing the closing and disconnecting functions of the switch, and abandoning the optical path switch column component commonly seen in traditional optical path switches. This innovation greatly simplifies the internal structure of the switch, making the entire system more compact and lightweight, reducing manufacturing costs, reducing components and thus reducing potential failure points.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] An optical micro switch comprises an upper cover, a base, a button, a terminal and a spring. The base is provided with a hole slot, and a group of optical coupling tubes are arranged on both sides of the hole slot. The spring has a lower extension plate extending downward, and the lower extension plate is dug with a through hole. When the button presses the spring, the through hole and the hole slot are overlapped or staggered to realize the connection or blocking of the optical path of the optical coupling tube.

[0007] The base is provided with a hole slot, and a pair of optical tubes are placed on both sides of the hole slot, which are the key components to realize the switch function. As an important component of the switch, the spring is unique in that the lower extension plate extends downward, and a through hole is cleverly dug on the lower extension plate. The design of this through hole enables the button to change the position of the through hole on the spring when it moves up and down, thereby realizing the overlap or stagger of the through hole and the hole slot. This dynamic change of overlap or stagger directly leads to the connection or blockage of the optical path of the light pair tube, thereby realizing the closing and disconnecting functions of the switch. The biggest advantage of this design is that it abandons the optical path switch column, which is common in traditional optical path switches. This innovation greatly simplifies the internal structure of the switch, making the entire system more compact and lightweight. At the same time, due to the reduction in the number of components, the assembly steps in the production process are simplified, thereby reducing manufacturing costs. In addition, this design also helps to improve the reliability and durability of the switch, because fewer components mean fewer potential failure points.

[0008] Preferably, a dustproof groove is dug on the upper surface of the button, and the upper cover is provided with a dustproof protrusion that cooperates with the dustproof groove.

[0009] The upper surface of the button is carefully dug with a dustproof groove, and the upper cover is equipped with a dustproof protrusion that perfectly matches it. The close combination of the dustproof groove and the dustproof protrusion forms a solid line of defense, effectively preventing the invasion of dust and impurities, thereby ensuring the cleanliness and hygiene of the inside of the switch. At the same time, it also makes the connection between the button and the upper cover more stable, the button is not prone to jitter, and ensures stable optical conduction.

[0010] Preferably, guide ridges are provided on both sides of the button, and the upper cover is provided with guide grooves matching with the guide ridges.

[0011] There are guide ribs on both sides of the button, and the upper cover is provided with matching guide grooves. The precise matching of the guide ribs and the guide grooves enables the button to move along a predetermined path when moving up and down, thus ensuring the accuracy and stability of the operation. This design not only improves the service life of the product, but also brings users a smoother and more comfortable control experience.

[0012] Preferably, an impact protrusion is provided at the bottom of the guide groove, and the top of the guide rib impacts the upper cover on the impact protrusion.

[0013] An impact protrusion is cleverly set at the bottom of the guide groove, and the top of the guide ridge collides with the upper cover during the movement of the button, and this collision point happens to be above the impact protrusion.

[0014] Preferably, there are multiple impact protrusions, and the multiple impact protrusions are evenly distributed.

[0015] There are more than one impact protrusion, which are evenly distributed at the bottom of the guide groove, which not only increases the contact area between the button and the upper cover, improving the stability and reliability of the operation, but also provides more uniform resistance when the button moves, making the operation feel smoother. In addition, the setting of multiple impact protrusions can also disperse the pressure, reduce the wear and tear that may be caused by a single impact point, and thus extend the service life of the product.

[0016] Preferably, the gaps between the plurality of impact protrusions form an echo recess cavity.

[0017] The core feature of the impact protrusion is that the gaps between multiple impact protrusions form an echo concave cavity. The impact protrusion is a protruding structure. When the user presses the button, the impact protrusion collides with the shell to make a sound. The echo concave cavity is a specially designed cavity located in the gap between the impact protrusions. The impact protrusion pushes air into this cavity to produce a sound feedback. This sound feedback is similar to the "click" sound of traditional mechanical buttons, providing users with instant operation confirmation and enhancing the sensory experience of interaction. The advantage of this design is that through auditory feedback, users can more intuitively perceive the effect of button operation. The design of the impact protrusion and the echo concave cavity increases the operability of the button, allowing users to obtain obvious sound feedback when pressing the button, thereby enhancing the pleasure of operation. Due to its simple structure and the absence of complex mechanical moving parts, this large volume button has high durability and can withstand long-term frequent use.

[0018] Preferably, the impact protrusion is in the shape of a quadrangular pyramid, and a plurality of impact protrusions are distributed in a rectangular array.

[0019] The shape of the impact bump is carefully designed to be a quadrangular pyramid, which is not only more stable in structure but also more distinctive in visual appearance. Multiple impact bumps are neatly arranged in a rectangular array, which is not only beautiful but also provides more uniform impact feedback in actual operation. The quadrangular pyramid design makes the impact point more concentrated, thereby improving the accuracy and sensitivity of the operation.

[0020] Preferably, the spring piece further comprises a spring piece body, and the lower extension piece is connected to the spring piece body and is orthogonal to each other.

[0021] The shrapnel includes a shrapnel body and a lower extension, which are orthogonal to each other. This structural design not only ensures the overall strength of the shrapnel, but also provides a solid foundation for the realization of its functions. Because the lower extension is innovatively extended on the basis of the shrapnel body, the optical path switch column, which is common in traditional optical path switches, can be abandoned. This innovation greatly simplifies the internal structure of the switch, making the entire system more compact and lightweight. At the same time, due to the reduction in the number of components, the assembly steps in the production process can be simplified, thereby reducing manufacturing costs. In addition, this design also helps to improve the reliability and durability of the switch, because fewer components mean fewer potential failure points.

[0022] Preferably, the button has a square shape.

[0023] The appearance design of the button adopts a square shape. This simple and classic geometric shape not only presents a stable and reliable image visually, but also shows many significant advantages in actual use. In actual use, the edges of the square button are clear, making it difficult for the button to shake under the constraint of the upper cover. This stability is essential to ensure the reliability of optical conduction. Since the button will not affect the connection or blocking of the optical path due to slight movement, the accuracy and consistency of the switch action are guaranteed. The stability of this design not only improves the overall performance of the product, but also reduces the possible misoperation caused by the shaking of the button, thereby improving the user's satisfaction. In addition, the design of the square button also simplifies the manufacturing process because it does not require complex curved surface processing, which helps to reduce production costs. At the same time, the regular shape of the square button also facilitates precise docking with other components, which not only improves assembly efficiency, but also makes it easier to repair and replace components.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] The optical micro switch of the utility model has a hole groove on the base, and a pair of optical pair tubes are placed on both sides of the hole groove, which are key components for realizing the switch function. As an important component of the switch, the spring is unique in that the lower extension plate extends downward, and a through hole is cleverly dug on the lower extension plate. The design of this through hole enables the button to change the position of the through hole on the spring when it moves up and down, thereby realizing the overlap or misalignment of the through hole and the hole groove. This dynamic change of overlap or misalignment directly leads to the connection or blocking of the optical path of the optical pair tube, thereby realizing the closing and disconnecting functions of the switch. The biggest advantage of this design is that it abandons the optical path switch column component commonly used in traditional optical path switches. This innovation greatly simplifies the internal structure of the switch, making the entire system more compact and lightweight. At the same time, due to the reduction in the number of components, the assembly steps in the production process are simplified, thereby reducing the manufacturing cost. In addition, this design also helps to improve the reliability and durability of the switch, because the reduction in components means the reduction of potential failure points.

[0034] The technical solution in this application will be described below in conjunction with the accompanying drawings.

The base 200 is provided with a hole slot 210, and a group of optical coupling tubes 600 are arranged on both sides of the hole slot 210. The spring 500 has a lower extension plate 510 extending downward, and the lower extension plate 510 is dug with a through hole 511. When the button 300 presses the spring 500, the through hole 511 coincides with or is offset from the hole slot 210 to achieve the connection or blocking of the optical path of the optical coupling tube 600.

[0036] The base 200 is provided with a hole slot 210, and a pair of optical tubes 600 are placed on both sides of the hole slot 210, which are key components for realizing the switch function. As an important component of the switch, the spring 500 is unique in that the lower extension sheet 510 extends downward, and a through hole 511 is cleverly dug on the lower extension sheet 510. The design of this through hole 511 enables the button 300 to change the position of the through hole 511 on the spring 500 when moving up and down, thereby realizing the overlap or misalignment of the through hole 511 and the hole slot 210. This dynamic change of overlap or misalignment directly leads to the connection or blockage of the optical path of the optical tube 600, thereby realizing the closing and disconnecting functions of the switch. The biggest advantage of this design is that it abandons the optical path switch column component commonly seen in traditional optical path switches. This innovation greatly simplifies the internal structure of the switch, making the entire system more compact and lightweight. At the same time, due to the reduction in the number of components, the assembly steps in the production process are simplified, thereby reducing the manufacturing cost. Additionally, this design helps improve the reliability and durability of the switch, as fewer parts means fewer potential points of failure.

[0038] The upper surface of the button 300 is carefully dug with a dustproof groove 310, and the upper cover 100 is correspondingly equipped with a dustproof protrusion 110 that perfectly matches it. The close combination of the dustproof groove 310 and the dustproof protrusion 110 forms a solid defense line, effectively preventing the invasion of dust and impurities, thereby ensuring the cleanliness and hygiene of the inside of the switch, and at the same time making the connection between the button 300 and the upper cover 100 more stable, the button 300 is not prone to jitter, ensuring stable optical conduction.

[0039] In this embodiment, guide ribs 320 are provided on both sides of the button 300 , and the upper cover 100 is provided with guide grooves 120 matched with the guide ribs 320 .

[0040] Guide ribs 320 are provided on both sides of the button 300, and the upper cover 100 is provided with matching guide grooves 120 accordingly. The precise matching of the guide ribs 320 and the guide grooves 120 enables the button 300 to move along a predetermined path when moving up and down, thereby ensuring the accuracy and stability of the operation. This design not only improves the service life of the product, but also brings a smoother and more comfortable control experience to the user.

[0041] In this embodiment, a collision protrusion 121 is provided at the bottom of the guide groove 120 , and the top of the guide rib 320 and the upper cover 100 collide with the collision protrusion 121 .

[0042] An impact protrusion 121 is cleverly provided at the bottom of the guide groove 120 , and the top of the guide rib 320 collides with the upper cover 100 during the movement of the button 300 , and the collision point is just located above the impact protrusion 121 .

[0043] In this embodiment, there are multiple impact protrusions 121 , and the multiple impact protrusions 121 are evenly distributed.

[0044] The number of the impact protrusions 121 is not just one, but multiple, and these impact protrusions 121 are evenly distributed at the bottom of the guide groove 120, which not only increases the contact area between the button 300 and the upper cover 100, improving the stability and reliability of the operation, but also provides more uniform resistance when the button 300 moves, making the operation feel smoother. In addition, the provision of multiple impact protrusions 121 can also disperse the pressure, reduce the wear that may be caused by a single impact point, and thus extend the service life of the product.

[0045] In this embodiment, the gaps between the plurality of impact protrusions 121 form an echo recess cavity 122 .

[0046] The core feature of the impact protrusion 121 is that the gaps between the multiple impact protrusions 121 form an echo recessed cavity 122. The impact protrusion 121 is a protruding structure. When the user presses the button 300, the impact protrusion 121 collides with the shell to make a sound.

[0050] The shrapnel 500 includes a shrapnel body 520 and a lower extension 510, which are orthogonal to each other. This structural design not only ensures the overall strength of the shrapnel 500, but also provides a solid foundation for the realization of its functions.

[0052] The appearance design of the button 300 adopts a square shape. This simple and classic geometric shape not only presents a stable and reliable image visually, but also shows many significant advantages in actual use. In actual use, the edges of the square button 300 are clear, so that the button 300 is not easy to shake under the constraint of the upper cover 100.
