Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hardware parts, and in particular relates to a rocker switch. Background Art
[0002] A rocker switch is a common electrical switch, mainly used to control the connection and disconnection of a circuit. Its appearance is similar to a seesaw, with a movable contact and a fixed contact. When the rocker switch is pressed, the movable contact will contact the fixed contact, thereby connecting the circuit; when the rocker switch is released, the movable contact will leave the fixed contact, thereby disconnecting the circuit. Due to its simple structure, low price, and easy use, rocker switches are widely used in electrical equipment in the fields of home, industry, and commerce, such as electric lights, electric fans, and motors. However, in the prior art, during the switching process, the contact surface between the movable contact and the fixed contact will move relative to each other at the contact point between the seesaw and the drive member. This movement will cause friction to be generated, especially when the contact area is small, the friction is relatively large, which not only generates noise but also reduces the service life of the switch due to excessive friction. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] like Figure 1-4As shown, a rocker switch comprises a button 1, a shell 2, a driving member 3 and a rocker 6; the middle part of the button 1 is hinged with the middle part of the shell 2; the button 1 is connected to the rocker 6 through the driving member 3; the shell 2 comprises a base and an outer shell, a static contact foot 4 is installed on one side of the base, there are two static contact feet 4, the two static contact feet 4 are arranged oppositely on the base, and a mounting opening is opened on the other side of the base; the rocker 6 is an L-shaped structure, the end of the L-shaped short side of the rocker 6 passes through the mounting opening and is clamped to the outside of the base, the L-shaped long side of the rocker 6 comprises two connecting pieces, a clamping space is formed between the two connecting pieces, and a moving contact 5 is arranged at the end of the connecting piece, the two sides of the bottom of the driving member 3 abut against the two connecting pieces, and the middle part of the bottom of the driving member 3 is located in the clamping space; grooves 7 are opened on both sides of the bottom of the driving member 3, and the groove 7 has a plurality of strips, A plurality of grooves 7 are arranged obliquely along the bottom of the driving member 3; the presence of the grooves 7 allows the lubricating oil to fully infiltrate the bottom of the driving member 3, forming a lubricating film, reducing the direct friction and wear between the driving member 3 and the seesaw 6, thereby enhancing its wear resistance, so that the mechanical system can work more smoothly and efficiently. The groove 7 design can effectively slow down the movement speed between the driving member 3 and the seesaw 6, and reduce the noise and vibration caused by friction. In addition, the presence of the lubricating film can also reduce the generation of friction sound, further reducing noise. By enhancing the wear resistance and lubricity between the driving member 3 and the seesaw 6, reducing wear and friction, the service life of the mechanical equipment can be effectively extended. At the same time, reducing noise and vibration can also reduce fatigue and damage of the mechanical equipment, further improving its life.
[0020] It also includes a spring 8 and a top column 9. The top column 9 is arranged in the driving member 3 and one end of the top column 9 protrudes from the bottom of the driving member 3. The button 1 is connected to the driving member 3 through the spring 8.
[0021] The working principle of a rocker switch involved in the utility model is as follows:
[0022] Attachment Figure 1 From the left and right perspective, when the left part of the button 1 is pressed, the bottom of the driving member 3 abuts against the rocker 6. During the pressing process, the pressure pushes the driving member 3 to rotate rightward with the hinge point of the button 1 and the housing 2 as the center. During the rotation of the driving member 3, the connecting piece of the rocker 6 is pressed down, so that the moving contact point 5 of the connecting piece abuts against the static contact foot 4 to form a passage.
[0023] When the right part of the button 1 is to be pressed, the bottom of the driving member 3 presses the connecting piece. During the pressing process, the pressure pushes the driving member 3 to rotate leftward with the hinge point of the button 1 and the shell 2 as the center, driving the driving member 3 to reset. At this time, the force exerted by the driving member 3 on the connecting piece gradually decreases, and the connecting piece gradually rises upward, so that the static contact foot 4 is separated from the moving contact 5, forming a circuit breaker.
[0024] The above describes some embodiments of the utility model in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
