Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a manual mute switch. Background Technology

[0002] The word "switch" is defined as turning on and off. It also refers to an electronic component that can open a circuit, interrupt current, or divert it to another circuit. The most common switches are electromechanical devices operated by humans, which have one or more electronic contacts. A manual switch is a switch that is pressed manually.

[0003] For example, Chinese patent CN219979390U discloses a push-button switch. The base and pressure plate together form a cavity containing a pressing component, an elastic component, a conductive element, and two contacts. A guide post is positioned on the side of the base facing the pressure plate. One end of the elastic component is fitted onto the guide post, and the other end passes through the guide post and connects to the pressing component. The two contacts are located on either side of the guide post, on the side of the conductive element facing the pressure plate. When the switch is pressed down, the pressing component and the elastic component drive the conductive element downwards, causing both ends of the conductive element to contact the two contacts. Disconnection; when the switch is pressed down again, the pressing component and the elastic component drive the conductive element to move upward so that the two ends of the conductive element contact the two contacts. This utility model uses an elastic component to control the on and off of the switch. Based on the pressing component driving the elastic component to pop up or compress, the conductive element is disconnected or connected with the contacts on both sides, preventing power waste caused by accidental switch touch. The overall structure of this push switch is simple, small in size, easy to operate, and safer. However, in this solution, the pressing component will collide with other structures and produce noise when it is pressed down, which will produce noise when switching on and off, making it unsuitable for places that require quiet. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a manual silent switch that solves the problem that when the pressing component is pressed down, it will collide with other structures and produce noise, making it unsuitable for quiet locations.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A manual mute switch includes: a switch housing, a first mounting cover on the top surface of the switch housing, a second mounting cover fixedly sleeved inside the first mounting cover, a switch button movably sleeved inside the second mounting cover, a movable bracket fixedly mounted on the bottom surface of the switch button, a spring provided on the outer wall surface, a switch bracket provided inside the switch housing, and the movable bracket movably sleeved with the switch bracket; and a mute component disposed on the bottom surface of the switch bracket for silencing when the switch button is pressed, the mute component including: a rubber pad disposed on the bottom surface of the switch bracket, a first rubber block fixedly mounted on the top surface of the rubber pad, two second rubber blocks fixedly mounted on the bottom surface of the rubber pad, a circuit board disposed on the bottom surface of the rubber pad, and two connecting holes formed on the top surface of the circuit board, the connecting holes movably sleeved with the second rubber blocks.

[0007] To support the circuit board, in a preferred embodiment of this invention, the switch bracket has two fixing blocks fixedly mounted on its bottom surface, a fixing plate fixedly mounted on the bottom surface of each fixing block, and a support plate fixedly mounted on one side of each fixing plate.

[0008] In order to avoid noise when the switch button base contacts the second mounting cover upwards, as a preferred embodiment of the present invention, the outer circular wall of the switch button is movably fitted with a first rubber ring.

[0009] To protect the circuit board, as a preferred embodiment of this invention, a rubber sheet is fixedly installed on the top surface of the support plate.

[0010] In order to connect the wires to the circuit board, as a preferred embodiment of the present invention, the bottom surface of the switch housing is provided with a mounting hole, and a connecting tube is fixedly sleeved on the inner circular wall of the mounting hole.

[0011] To avoid friction between the wire and the connecting pipe, as a preferred embodiment of this invention, a second rubber ring is fixedly fitted onto the inner circular wall of the connecting pipe.

[0012] In summary, the present invention has the following main advantages:

[0013] By setting up rubber pads, the rubber pad circuit board can be assembled first, and then the assembled rubber pad and circuit board can be fixed to the bottom of the switch bracket with hot melt adhesive. When the switch button is pressed, the switch button and the movable bracket move downward to compress the spring. The downward-moving movable bracket will then press against the first rubber block at the bottom of the switch bracket. The first rubber block absorbs the vibration energy when it is impacted by the movable bracket, thereby reducing the noise of the movable bracket hitting downward. This greatly reduces the noise generated when the switch button is pressed, making it suitable for places where quiet is required. Attached Figure Description

A second mounting cover 3 is fixedly sleeved inside the first mounting cover 2. A switch button 4 is movably sleeved inside the second mounting cover 3. A movable bracket 5 is fixedly mounted on the bottom surface of the switch button 4. A spring 7 is provided on the outer wall surface. A switch bracket 6 is provided inside the switch housing 1, and the movable bracket 5 is movably sleeved with the switch bracket 6. A mute component is provided on the bottom surface of the switch bracket 6 for silencing when the switch button 4 is pressed. The mute component includes: a rubber pad 8, which is located on the bottom surface of the switch bracket 6. A first rubber block 9 is fixedly mounted on the top surface of the rubber pad 8. Two second rubber blocks 10 are fixedly mounted on the bottom surface of the rubber pad 8. A circuit board 11 is provided on the bottom surface of the rubber pad 8, and an opening is provided on the top surface of the circuit board 11. There are two connecting holes 12, which are movably connected to the second rubber block 10. By setting a rubber pad 8, the second rubber block 10 on the rubber pad 8 can be inserted into the interior of the connecting hole 12 on the circuit board 11, so that the rubber pad 8 and the circuit board 11 are assembled together. Then, the assembled rubber pad 8 and the circuit board 11 are fixed to the bottom of the switch bracket 6 with hot melt adhesive, and the rubber pad 8 is in contact with the bottom of the switch bracket 6. When the switch button 4 is pressed, the switch button 4 and the movable bracket 5 move downward to compress the spring 7. The downwardly moving movable bracket 5 will abut against the first rubber block 9 at the bottom of the switch bracket 6. The first rubber block 9 will absorb the vibration energy when it is hit by the movable bracket 5, thereby reducing the noise of the movable bracket 5 hitting downward, which greatly reduces the noise generated when the switch button 4 is pressed, making it suitable for places that require quiet.

[0022] Example 2

[0023] Based on the above embodiment 1, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4Two fixing blocks 13 are fixedly installed on the bottom surface of the switch bracket 6. A fixing plate 14 is fixedly installed on the bottom surface of the fixing blocks 13. A support plate 16 is fixedly installed on one side of the fixing plate 14. By setting the support plate 16, after the rubber pad 8 and the circuit board 11 are installed at the bottom of the switch bracket 6 with hot melt adhesive, the support plate 16 will abut against the bottom of the circuit board 11 to support the circuit board 11, preventing the movable bracket 5 from hitting the first rubber block 9 downward for a long time, which would cause the rubber pad 8 and the circuit board 11 to deviate from their positions. A first rubber ring 17 is movably sleeved on the outer circular wall of the switch button 4. By setting the first rubber ring 17, after the switch button 4 is pressed, the switch button 4 and the movable bracket 5 will be pushed upward by the elastic force released by the spring 7. This design avoids the noise generated when the base of the switch button 4 contacts the second mounting cover 3 when the spring 7 rebounds, thus improving the quietness when pressing the switch button 4. A rubber sheet 15 is fixedly installed on the top surface of the support plate 16 to protect the circuit board 11. A mounting hole 18 is provided on the bottom surface of the switch housing 1. A connecting tube 19 is fixedly sleeved on the inner circular wall of the mounting hole 18. By setting the connecting tube 19, the wires can enter the interior of the switch housing 1 and connect to the circuit board 11 through the connecting tube 19. The wiring connection method of the circuit board 11 is existing technology and will not be described in detail in this solution. A second rubber ring 20 is fixedly sleeved on the inner circular wall of the connecting tube 19 to prevent friction between the wires and the connecting tube 19.

[0024] refer to Figures 1-4 As shown, by setting the rubber pad 8, the second rubber block 10 on the rubber pad 8 can be inserted into the connection hole 12 on the circuit board 11, so that the rubber pad 8 and the circuit board 11 are assembled together. Then, the assembled rubber pad 8 and the circuit board 11 are fixed to the bottom of the switch bracket 6 with hot melt adhesive, and the rubber pad 8 is in contact with the bottom of the switch bracket 6. When the switch button 4 is pressed, the switch button 4 and the movable bracket 5 move downward to compress the spring 7. The downwardly moving movable bracket 5 will abut against the first rubber block 9 at the bottom of the switch bracket 6. The first rubber block 9 will absorb the vibration energy when it is hit by the movable bracket 5, thereby reducing the noise of the movable bracket 5 hitting downward. After the switch button 4 is pressed, the switch button 4 and the movable bracket 5 will be pushed upward by the elastic force released by the spring 7. The first rubber ring 17 can prevent the sound generated when the base of the switch button 4 contacts the second mounting cover 3 when the spring 7 rebounds, greatly reducing the noise generated when pressing the switch button 4, which is suitable for places that require quiet.
