[0031] like Figure 1-4 As shown, a product switch button 5 structure based on light conduction, the product switch button 5 structure includes: an upper cover 1, a PCB board 2, a plurality of lamp beads 3, a light conduction member 4 and a button 5;

[0032] The middle part of the upper cover 1 is provided with an annular channel 101 extending from the bottom to the top; the PCB board 2 is arranged on the bottom of the upper cover 1, and an on-off switch 6 for triggering the on-off of the product circuit is arranged on the PCB board 2, and the on-off switch 6 is located directly below the center of the annular channel 101; a plurality of lamp beads 3 are arranged on the PCB board 2, and are arranged at intervals around the outer direction of the annular channel 101; the light transmission member 4 is made of a transparent soft material, and the light transmission member 4 includes a first annular transmission part 401 and a second cylindrical transmission part 402. Part 402, the first conducting part 401 is horizontally arranged and pressed on a plurality of lamp beads 3, one end of the second conducting part 402 is connected to the inner ring edge of the first conducting part 401, and the other end of the second conducting part 402 is located in the annular channel 101 to form a circle of light conduction belt, and the outer wall of the second conducting part 402 is in contact with the inner wall of the annular channel 101; the button 5 is arranged in the second conducting part 402, forming an integral structure with the second conducting part 402, and the button 5 is located on the inner surface of the second conducting part 402 and contacts with the on-off switch 6.

[0033] Specifically, the first embodiment provides a product switch button 5 structure based on light conduction, by installing a circle of light conduction members 4 in the annular channel 101 where the button 5 is set, so that when the button 5 is pressed, the light conduction members 4 evenly conduct the light source to the periphery of the button 5, thereby enhancing the design aesthetics and technological sense of the button 5, thereby improving the user experience. During implementation, a penetrating annular channel 101 is set in the middle of the upper cover 1, and the PCB board 2 is installed at the bottom of the upper cover 1, so that the on-off switch 6 located on the PCB board 2 is located below the annular channel 101. The center of the annular channel 101 is then taken as a reference, and several lamp beads 3 are arranged around the PCB board 2. At the same time, a light transmission member 4 is arranged between the annular channel 101 and the PCB board 2, so that the first transmission part 401 of the light transmission member 4 is pressed on the lamp bead 3, and the second transmission part 402 is arranged around the inner wall of the annular channel 101, so that when the on-off switch 6 is pressed, the lamp bead 3 is powered on and emits light, and then the light of the light bead is transmitted to the second transmission part 402 through the first transmission part 401, so as to form uniform light around the periphery of the annular channel 101. The design method of the switch button 5 structure enhances the design aesthetics and technological sense of the button 5, and improves the user experience.

[0034] Furthermore, with respect to the design quantity of the lamp beads 3, this embodiment proposes a specific implementation method, in which the number of the lamp beads 3 can be designed to be 4, and the lamp beads 3 are arranged on the PCB board 2 at equal intervals with the center of the annular channel 101 as a reference.

[0035] In some possible embodiments, the product switch button 5 structure also includes: a retaining ring 102, the retaining ring 102 is made of an opaque material and is coaxially arranged with the annular channel 101, the top edge of the retaining ring 102 is integrally connected to the bottom of the upper cover 1, and the bottom cover of the retaining ring 102 is arranged on the periphery of a plurality of lamp beads 3.

[0036] In the above embodiment, the lamp beads 3 are covered by the retaining ring 102 to gather the light source in the area of ​​the annular channel 101, thereby preventing the light source from diffusing and leaking out and better gathering the light source together, so that the lighting effect is better;

[0037] In some possible implementations, the lamp bead 3 and the second conducting part 402 are arranged at intervals.

[0038] This is because the lamp bead 3 and the second conducting part 402 need to maintain a certain distance to diffuse the light more evenly on the second conducting part 402, thereby making the light on the second conducting part 402 more stable. Specifically, the distance between the lamp bead 3 and the second conducting part 402 is 2.5-5 mm. In this embodiment, it can be preferably 3 mm.

[0039] In some possible implementations, a reflective layer 201 is provided on the PCB board 2 in the area where the retaining ring 102 is provided.

[0040] In this way, the light source can reflect the light in the direction of the annular channel 101 through the reflective layer 201 , thereby making the light presentation effect on the light-conducting member 4 better.

[0041] In some possible implementations, the light transmission component 4 further includes: a pair of mounting tentacles 403 , one end of the pair of mounting tentacles 403 is disposed on the outer edge of the first transmission portion 401 , and the other end of the pair of mounting tentacles 403 is detachably connected to the upper cover 1 .

[0042] Specifically, a circular hole is provided at the other end of the pair of mounting tentacles 403, and the mounting tentacles 403 are connected to the upper cover 1 by pins.

[0043] In some possible embodiments, the outer edge of the upper cover 1 is also provided with a connection structure, and the connection structure is used to connect the components of the product. In order to achieve a better connection effect, a plurality of connection structures can be provided, and they are arranged at equal intervals on the outer edge of the upper cover 1. Furthermore, the connection structure can be provided as a buckle, so that it can be buckled with the outer edge of the upper cover 1 through the buckle.

[0044] In some possible implementations, the top surface of the upper cover 1 is located at the periphery of the annular channel 101 to form a smooth concave slope.

[0045] In this way, the area where the annular channel 101 is located, that is, the area where the button is located, is more clearly identified, and the position of the button can be identified by touch through the smooth concave slope. In this way, when the user uses it, even without visual observation, the position of the button can be clearly touched through this design, thereby improving the user experience.

[0046] In some possible implementations, an adhesive layer is provided at the contact portion between the key 5 and the second conducting part 402 to adhere the key 5 and the second conducting part 402 into an integrated structure, so that the second conducting part 402 and the key 5 form a good sealing effect, thereby avoiding the drawback of uneven light transmission on the second conducting part 402 caused by leakage of the light source. Furthermore, the lamp bead 3 is an LED lamp, and the color of the light source can be selected according to the effect presented.
