As shown in fig. 1 to 3, the present embodiment provides a key conducting structure, which includes a fixed shaft 10, a conducting contact member 20, a pressing member 30 and a rebound member 40; the conductive pressing member 20 of the embodiment is rotatably sleeved on the fixed shaft 10, and the conductive pressing member 20 is respectively provided with a pressing portion 21 and a force receiving portion 22 at intervals; the pressing piece 30 is matched with the force receiving portion 22 of the conductive pressing piece 20, the rebound piece 40 is abutted against the conductive pressing piece 20, and when the pressing piece 30 drives the force receiving portion 22 of the conductive pressing piece 20, the conductive pressing piece 20 and the pressing portion 21 thereof can be driven to rotate relative to the fixed shaft 10, so that the pressing portion 21 can press the pressing switch 51 of the PCB 50.

As shown in fig. 4, in order to prevent the pressing portion 21 from pressing the pressing switch 51 of the PCB 50 due to an excessively large movement stroke of the conductive pressing member 20, in this embodiment, a limiting portion 11 is disposed on an outer sidewall of the fixed shaft 10, and the limiting portion 11 is spaced from the conductive pressing member 20. In this way, when the pressing piece 30 drives the conductive pressing piece 20 to rotate relative to the fixed shaft 10, the maximum rotation stroke of the conductive pressing piece 20 can rotate to abut against the limiting part 11 on the fixed shaft 10. Thus, the excessive movement stroke of the conductive contact 20 can be effectively prevented by the limiting action of the limiting part 11 on the fixed shaft 10. The motion stroke of the conductive pressing member 20 is slightly larger than the distance between the pressing portion 21 and the pressing switch 51 of the PCB 50, so that the pressing of the pressing portion 21 and the pressing switch 51 of the PCB 50 can be realized, and the phenomenon that the pressing switch 51 of the PCB 50 is damaged due to the overlarge motion stroke of the conductive pressing member 20 can be prevented.

The limiting portion 11 of the present embodiment may be, but is not limited to, a fan-shaped protrusion structure provided on an outer sidewall of the fixed shaft 10. In addition, as shown in fig. 4, in order to prevent the fixed shaft 10 from moving in the axial direction, the fixed shaft 10 of the present embodiment is radially provided with a stopper 12.

As shown in fig. 5, the conductive contact 20 of the present embodiment further includes an arc-shaped collar 23 for being sleeved on the fixed shaft 10, and the arc-shaped collar 23 has a ring-shaped structure with a notch. In this way, the conductive pressing member 20 of the present embodiment is rotatably sleeved on the fixed shaft 10 through the arc-shaped collar 23 thereof, and the notch of the arc-shaped collar 23 is matched with the fan-shaped protrusion on the fixed shaft 10; when the pressing piece 30 drives the conductive pressing piece 20 to rotate, one end face of the notch on the arc-shaped lantern ring 23 stops rotating when the notch abuts against the fan-shaped bulge, so that the effect of controlling the action stroke of the conductive pressing piece 20 is achieved.

The key conducting structure of the present embodiment further includes a housing 60, wherein the fixing shaft 10 is fixedly disposed in the housing 60, the pressing member 30 is telescopically disposed on the housing 60, and an opening is disposed on an outer side wall of the housing 60, such that an end of the pressing member 30 away from the conducting contact 20 is disposed in the opening of the housing 60. Therefore, after the user applies force to one end of the pressing member 30 located at the opening of the housing 60, the pressing member 30 can be driven to extend into the housing 60 and drive the conductive contact member 20 to rotate.

In order to better drive the conductive contact 20 to rotate, the pressing member 30 of the present embodiment includes a key portion 31 and a first rail groove 32, where the key portion 31 is connected to the first rail groove 32. The force receiving portion 22 of the conductive contact 20 is an arc-shaped protrusion, and the first rail groove 32 of the pressing member 30 abuts against the force receiving portion 22. Therefore, the pressing piece 30 of the embodiment is provided with the first guide rail groove 32 at one end opposite to the conductive pressing piece 20, and the force receiving portion 22 of the conductive pressing piece 20 is pushed and simultaneously the force receiving portion 22 can be effectively prevented from derailing or jamming by the limiting function of the first guide rail groove 32.

The first rail groove 32 of the present embodiment may be, but is not limited to, a U-shaped groove structure, and the length of the groove of the first rail groove 32 is much longer than the motion stroke of the conductive contact 20. Therefore, the force receiving portion 22 of the present embodiment abuts against the first guide rail groove 32, and through the U-shaped design of the first guide rail groove 32, the force receiving portion 22 can be effectively prevented from sliding out of the first guide rail groove 32, and the force receiving portion 22 is ensured to be always located in the first guide rail groove 32.

As shown in fig. 6, the pressing member 30 of the present embodiment further includes a limiting base 33, the key portion 31 and the first rail groove 32 are respectively disposed at two ends of the limiting base 33, and the pressing surface of the key portion 31 and the groove surface of the first rail groove 32 may be disposed in parallel or inclined.

Further, in the present embodiment, by providing a design that the pressing surface of the key portion 31 and the groove surface of the first rail groove 32 can be parallel or inclined, the pressing member 30 is beneficial to the angle adjustment of the switch operation panel of different electronic products, so that the angle design of the switch operation panel of different electronic products can be applied according to the design of different angles required by actual production, thereby improving the applicability of the key conductive structure of the present embodiment.

As shown in fig. 6 and 7, in the present embodiment, the guiding slider 61 is disposed on the inner side wall of the housing 60, and the limiting base 33 of the pressing member 30 is provided with a limiting sliding hole 331 at a position opposite to the guiding slider 61, so that the limiting base 33 is slidably disposed on the guiding slider 61 of the housing 60 through the limiting sliding hole 331. In order to make the sliding of the limit base 33 smoother, in the present embodiment, two supporting sliders 62 are disposed on the inner sidewall of the housing 60, the two supporting sliders 62 are disposed at intervals respectively and below the guiding sliders 61, the bottom of the limit base 33 of the pressing member 30 slidably abuts against the tops of the two supporting sliders 62, and a partition 332 is disposed in the middle of the bottom of the limit base 33, so that the partition 332 divides the bottom of the limit base 33 into two abutting portions, and the two abutting portions of the limit base 33 abut against the tops of the two supporting sliders 62 respectively, and the partition 332 can be inserted into a space between the two supporting sliders 62 during the sliding process of the limit base 33 to perform a limiting function, thereby preventing the limit base 33 from shifting during the sliding process.

As shown in fig. 2 and 3, the rebound member 40 of the present embodiment includes a rebound rod 41 and a telescopic spring 42, wherein one end of the rebound rod 41 abuts against the conductive contact member 20, the other end of the rebound rod 41 is connected with one end of the telescopic spring 42, and the other end of the telescopic spring 42 is fixed in the housing 60.

Similarly, in order to prevent derailment or jamming between the rebound bar 41 and the conductive contact member 20, in the present embodiment, the second rail groove 24 is disposed at a position where the conductive contact member 20 abuts against the rebound bar 41, and the second rail groove 24 may be, but is not limited to, a U-shaped groove structure. Further, the housing 60 of the present embodiment is provided with a cavity accommodating the extension spring 42 and the rebound lever 41, the top of the rebound lever 41 is of a hemispherical structure, and the top of the rebound lever 41 abuts against the middle of the second rail groove 24. Thus, when the conductive contact 20 rotates, the second guide rail groove 24 can push the hemispherical top of the resilient rod 41 and make the resilient rod 41 move in the direction of compressing the expansion spring 42, when the contact 30 is released, the resilient rod 41 is pushed by the expansion spring 42 and moves in the direction of expanding the expansion spring 42 under the condition that no external force is applied to the conductive contact 20, and at this time, the resilient rod 41 can push the second guide rail groove 24 of the conductive contact 20 to move through the hemispherical top thereof, so as to drive the conductive contact 20 to reversely rotate. Wherein, in the process of the interaction of the rebound lever 41 and the second guide rail groove 24, the U-shaped design of the second guide rail groove 24 can effectively prevent the top of the rebound lever 41 from sliding out of the second guide rail groove 24, so as to ensure that the top of the rebound lever 41 is always positioned in the first guide rail groove 32.

In addition, a PCB 50 is disposed in the housing 60 of the present embodiment, and a touch switch 51 is disposed on the PCB 50, and when the pressing member 30 drives the conductive pressing member 20 to rotate, the touch portion 21 on the conductive pressing member 20 is simultaneously driven to touch the touch switch 51 on the PCB 50.

Therefore, in the key conducting structure of the present embodiment, first, the pressing member 30 is pressed by pressing the key portion 31 at the opening of the housing 60, and the pressing member 30 moves inwards on the supporting slider 62 of the housing 60 through the limiting base 33 thereof, so that the first rail groove 32 at the other end of the pressing member 30 can push the force receiving portion 22 on the conducting contact member 20, thereby driving the conducting contact member 20 to rotate relative to the fixed shaft 10. When the arc collar 23 of the conductive contact 20 rotates to abut against the limit part 11 of the fixed shaft 10, the contact part 21 of the conductive contact 20 just contacts the contact switch 51 on the PCB 50; when the conductive pressing piece 20 rotates, the second guide rail groove 24 on the conductive pressing piece 20 pushes the top of the rebound rod 41 and enables the rebound rod 41 to move towards the direction of compressing the telescopic spring 42, so that when the pressing piece 30 is released, the rebound rod 41 is pushed by the telescopic spring 42 and moves towards the direction of stretching the telescopic spring 42 under the condition that no external force exists on the conductive pressing piece 20, and at the moment, the rebound rod 41 can push the second guide rail groove 24 of the conductive pressing piece 20 to move through the hemispherical top of the rebound rod 41, and further the conductive pressing piece 20 is driven to reversely rotate; and then the first guide rail groove 32 of the pressing piece 30 is reversely pushed by the stress part 22 on the conductive pressing piece 20, so that the conductive pressing piece 20 and the pressing piece 30 realize the reset function.

Compared with the prior art, the beneficial effects of the embodiment are as follows: the key conducting structure of the embodiment has a simple and attractive overall structure, adopts the ingenious design that the conducting contact piece 20 is rotatably sleeved on the fixed shaft 10, and can drive the stress part 22 of the conducting contact piece 20 through the pressing piece 30 to drive the contact part 21 of the conducting contact piece 20 to rotate, so that the function of contacting the contact switch 51 on the PCB 50 is realized; therefore, the angles between the pressing surface of the pressing member 30 and the working surface of the pressing member 30 and the conductive contact member 20 can be designed to be different angles, and the angle design of the operation panel of different electronic products can be applied according to the design of different angles required by actual production. In addition, the fan-shaped bulge is arranged on the fixed shaft 10, so that the overlarge rotation stroke of the conductive pressing piece 20 is prevented, and the phenomenon that the PCB 50 and keys on the PCB 50 are damaged due to the action stroke of the conductive pressing piece 20 is effectively prevented; the resilient member 40 is effective to achieve automatic resetting of the conductive contact member 20 and the pressing member 30.
