Description

Technical Field

[0001] This utility model relates to the field of rocker switch technology, and specifically to a rocker switch with a long lifespan. Background Technology

[0002] Traditional lever switches are widely used in the automotive industry, and one of their core components is the lever structure. The lever controls the on / off state of the switch by contacting the microswitch. However, due to the change in angle of the lever during rotation, the direction of the force applied to the microswitch by the lever's pressing end changes, resulting in uneven force distribution. This uneven force distribution adversely affects the operation of the microswitch, not only causing poor contact and affecting the stability and reliability of the switch, but also potentially accelerating the mechanical wear of the microswitch, thereby shortening its service life. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a long-life rocker switch.

[0004] The technical solution adopted by this utility model is as follows: This application provides a long-life rocker switch, including a base, a button, a circuit board disposed in the base, and a micro switch disposed on the circuit board. The micro switch includes a trigger end and a pressure head driven by the button. The force direction of the pressure head is different from that of the trigger end, and the pressure head always acts perpendicularly to the trigger end.

[0005] In some embodiments, a pressure rod is rotatably disposed within the base. The pressure rod is driven to rotate by a button. A pressure head is rotatably disposed at one end of the pressure rod near the micro switch. The pressure head includes a contact surface, which is always in contact with the trigger end.

[0006] In some embodiments, a lever is rotatably disposed within the base, with one end of the lever away from the micro switch connected to a button, and the other end abutting against a pressure head and / or a pressure rod.

[0007] In some embodiments, the trigger end is a horizontally arranged pressing plane, and the contact plane is always in contact with the pressing plane.

[0008] In some embodiments, the pressure rod is provided with a mounting shaft at one end near the micro switch, and a snap-fit ​​cavity adapted to the mounting shaft is provided on the side of the pressure head away from the trigger end. The snap-fit ​​cavity has an opening for the mounting shaft to be snapped in and removed.

[0009] In some embodiments, the opening is provided with a guide port that opens outwards.

[0010] In some embodiments, the pressure head has a groove on the side facing the trigger end, the contact plane is disposed in the groove, and the trigger end extends into the groove.

[0011] In some embodiments, a lever is rotatably disposed within the base, one end of the lever away from the micro switch is connected to a button, and the other end is rotatably disposed with a pressure head, the pressure head including a contact plane, the contact plane always being in contact with the trigger end.

[0012] In some embodiments, a lever is rotatably disposed within the base, with one end of the lever away from the micro switch connected to a button, and the other end abutting against the pressure head, which is slidably disposed within the base in a direction perpendicular to the trigger end.

[0013] The beneficial effects of this utility model are as follows: In this utility model, when the force direction of the pressure head is different from that of the trigger end of the micro switch, the pressure head is always perpendicular to the trigger end of the micro switch and is not affected by the force angle of the pressure head.

[0024] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] Regarding the accompanying drawings of this application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0026] Example 1:

[0027] Traditional lever switches typically use a button to rotate a lever, which in turn triggers a microswitch on the circuit board. However, the pressure end of the lever generates a component force as the lever angle changes, causing uneven force on the microswitch and thus affecting its lifespan.

[0028] like Figures 1 to 5As shown, this embodiment provides a long-life rocker switch, including a base 1, a button 2, a circuit board 3 disposed within the base 1, a micro switch 4 disposed on the circuit board 3, and a pressure head 5 driven by the button 2. Typically, a transmission assembly is provided between the button 2 and the pressure head 5. The micro switch 4 includes a trigger end 40, generally a push-button type. Since it is a rocker switch, the force direction of the pressure head 5 is different from the force direction of the trigger end 40. However, in this embodiment, the pressure head 5 is always operated perpendicularly. Specifically, at the trigger end 40, a pressure rod 6 is rotatably disposed within the base 1. The pressure rod 6 is driven to rotate by the button 2. The pressure head 5 is rotatably disposed at one end of the pressure rod 6 near the micro switch 4. Preferably, one end of the pressure rod 6 is hinged to the base 1, and the other end is rotatably disposed with the pressure head 5. The pressure head 5 includes a contact plane 50, which is always in contact with the trigger end 40. Preferably, the trigger end 40 is a horizontally disposed pressing plane, and the contact plane 50 is always in contact with the pressing plane.

[0029] In this way, even when the force direction of the pressure head 5 is different from that of the trigger end of the micro switch, the pressure head 5 is always perpendicular to the trigger end 40 of the micro switch 4 and is not affected by the force angle of the pressure head 5, that is, it is not affected by the angle of the pressure rod 6. This makes the micro switch uniformly stressed, reduces the probability of poor contact, improves the stability and reliability of the switch, and extends the service life of the switch.

[0030] In this embodiment of the present disclosure, a lever 7 is rotatably disposed inside the base 1. One end of the lever 7 away from the micro switch 4 is connected to the button 2, and the other end abuts against the pressure head 5 and / or the pressure rod 6, thus ensuring that the pressure head 5 always applies force vertically to the trigger end 40.

[0031] Secondly, the pressure rod 6 is provided with a mounting shaft 60 at one end near the micro switch 4, and the pressure head 5 is provided with a snap-fit ​​cavity 51 on the side away from the trigger end 40, which is adapted to the mounting shaft 60. The snap-fit ​​cavity 51 has an opening 52 for the mounting shaft 60 to be snapped in and out. The two side walls constituting the snap-fit ​​cavity 51 are deformable. Optionally, the pressure head 5 is made of materials such as plastic or rubber.

[0032] Furthermore, the opening 52 is provided with a guide port 53 that opens outward to facilitate the quick assembly of the pressure head 5 and the pressure rod 6.

[0033] Optionally, the pressure head 5 is provided with a groove 54 on the side facing the trigger end 40, the contact plane 50 is disposed in the groove 54, and the trigger end 40 extends into the groove 54, ensuring that the trigger end 40 and the contact plane 50 are precisely aligned, thereby improving the reliability of the structure.

[0034] Example 2:

[0035] Unlike Embodiment 1, in this embodiment, a lever 7 is rotatably disposed inside the base 1. One end of the lever 7 away from the micro switch 4 is connected to the button 2, and the other end is rotatably disposed with the pressure head 5. The pressure head 5 includes a contact plane 50, which is always in contact with the trigger end 40. The pressure lever 6 is eliminated, and the pressure head 5 is directly rotatably disposed on the lever 7, which can also achieve the same result as the pressure head 5 always acting perpendicularly on the trigger end 40.

[0036] Example 3:

[0037] Unlike Embodiment 1 and Embodiment 2, in this embodiment, a lever 7 is rotatably disposed inside the base 1. One end of the lever 7 away from the micro switch 4 is connected to the button 2, and the other end abuts against the pressure head 5. The pressure head 5 is slidably disposed inside the base 1 in a direction perpendicular to the trigger end 40. Thus, the pressure head 5 can only move in a direction perpendicular to the trigger end 40 to press the trigger end 40, and the lever 7 only needs to push the pressure head 5 to move.

[0038] It should be understood that there are various structures for the pressure head 5 to slide within the base 1, such as the structure of the protrusion and the slide rail, which will not be described in detail here.

[0039] It should be understood that button 2 can be equipped with a separate reset structure, which can be achieved by means of springs, contact springs, or the reset structure of micro switch 4.

[0040] In summary, after reading this detailed disclosure, those skilled in the art will understand that the foregoing detailed disclosure is presented by way of example only and is not restrictive. Although not explicitly stated herein, those skilled in the art will understand that the requirements of this application encompass various reasonable changes, improvements, and modifications to the embodiments. These changes, improvements, and modifications are intended to be made by this application and are within the spirit and scope of the exemplary embodiments of this application.

[0041] Furthermore, it should be understood that in the foregoing description of the embodiments of this application, various features are combined in a single embodiment, drawing, or description for the purpose of simplifying the understanding of a feature. However, this does not mean that the combination of these features is necessary, and those skilled in the art may readily identify some of the devices as separate embodiments when reading this application. That is, the embodiments in this application can also be understood as an integration of multiple sub-embodiments.
