[0023] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] As Figures 1 to 4 shown, a light - transmissive button, characterized in that it includes a bottom shell 1 and a face shell 2. The bottom shell 1 is snap - connected to the face shell 2, and an accommodation space is formed between the bottom shell 1 and the face shell 2. A circuit board 3 is provided in the accommodation space. An LED lamp 4 is provided on the circuit board 3. The face shell 2 is provided with a button hole 11, and a button 5 is provided at the position of the button hole 11. The button 5 is provided with a light - transmissive hole 51 communicating with the outside. A silica gel pad 6 is provided between the button 5 and the circuit board 3. The silica gel pad 6 is provided with a through - hole 61. A light guide column 7 is provided on the lower side of the silica gel pad 6. The upper side of the light guide column 7 extends to the upper side surface position of the button 5 through the through - hole 61 and the light - transmissive hole 51.

[0027] The light guide column 7 is passed through the silica gel pad 6 and the button 5, so that the light of the LED lamp 4 arranged on the upper side of the circuit board 3 can directly propagate from the position of the light guide column 7 to the upper side of the button 5, thus forming a button 5 with a light - transmissive effect. For the silica gel pad 6 and the button 5, no special treatment is required, and the production cost is reduced without affecting the use effect.

[0028] At this time, in order for the button 5 to form a signal input during use, in this embodiment, a dome switch 8 is provided on the upper side of the circuit board 3, and the bottom of the light guide column 7 is located above the dome switch 8. In this way, when the button 5 is pressed, the light guide column 7 moves downward at the same time, thereby pressing down the dome switch 8, and then the dome switch 8 abuts against the circuit board 3 to form a signal input.

[0029] The silicone pad 6 is used to provide a restoring elastic force for the button 5. Therefore, in this embodiment, the silicone pad 6 includes a main body 62 and an annular protrusion 63 provided on the lower side of the button 5. The through hole 61 is provided in the middle of the annular protrusion 63. A groove 52 corresponding to the annular protrusion 63 is provided on the lower side surface of the button 5. The button 5 is arranged on the upper side of the silicone pad 6 through the groove 52 and the annular protrusion 63. At this time, the main body 62 of the silicone pad 6 is fixed between the bottom case 1 and the face case 2. At this time, the silicone pad 6 is arranged on the lower side of the button 5, and the button 5 is fixed on the upper side of the annular protrusion 63 of the silicone pad 6. At this time, in order to prevent the button 5 from detaching from the button hole 11 of the face cover, an outer folded edge is provided around the button 5, and the size of the outer folded edge is larger than the size of the button hole 11. In this way, the button 5 can be prevented from detaching at the position of the button hole 11. At the same time, the annular protrusion 63 of the silicone pad 6 is arranged on the lower side of the button 5, which can provide an upward force for the button 5 after being pressed, so that the button 5 returns to its original position.

[0030] At this time, the button 5 is arranged on the upper side of the silicone pad 6. In order to keep the button 5 and the silicone pad 6 moving up and down synchronously, in this embodiment, the groove 52 of the button 5 and the annular protrusion 63 of the silicone pad 6 are in interference fit. Through the interference fit, the button 5 is fixed on the outside of the annular protrusion 63 of the silicone pad 6 through the groove 52, thereby fixing the button 5 and the silicone pad 6, and at the same time avoiding the problems of the button 5 loosening and shaking during use, and also avoiding the problem of the pressing cavity feeling of the button 5 during use.

[0031] In order to make the reset effect of the button 5 better after being pressed, in this embodiment, an elastic arm 64 is provided between the annular protrusion 63 and the main body 62 of the silicone pad 6. The elastic arm 64 is made of inclined silicone. After the elastic arm 64 is provided, the elasticity of the silicone pad 6 at the position of the elastic arm 64 can be further increased, thereby further increasing the reset effect of the annular protrusion 63 and the button 5.

[0032] At this time, for the convenience of production, the main body 62, the elastic arm 64 and the annular protrusion 63 of the silicone pad 6 are integrally formed. Specifically, the elastic arm 64 is an inclined part provided between the main body 62 and the annular protrusion 63 of the silicone pad 6. The silicone pad 6 (main body 62, elastic arm 64, annular protrusion 63) is integrally formed as a whole, so that the elastic arm 64 can provide a certain elastic force during use and also facilitate the production of the silicone pad 6.

[0033] Since the light guide column 7 passes through the silica gel pad 6, in order to avoid light leakage, in this embodiment, the silica gel pad 6 is black. The overall black color of the silica gel pad 6 can wrap the light guide column 7 entirely, so that light will not transmit through the gap between the light guide column 7 and the silica gel pad 6 (the annular protrusion 63). At the same time, the light guide column 7 is red. During use, a red light spot can be observed from the outside of the button 5 through the red light guide column 7, thus forming a button 5 with a specific characteristic light emission.

[0034] The light guide column 7 is used for light transmission at this time and also for transmitting the pressing force. Specifically, in this embodiment, the light guide column 7 includes a middle part 71. The middle part 71 is clamped at the inner groove position of the annular protrusion 63. The upper side of the middle part 71 is an upper light-transmitting part 72 that passes through the through hole 61 of the silica gel pad 6 and the light-transmitting hole 51 of the button 5. The lower side of the middle part 71 is provided with a lower pressing part 73. The lower pressing part 73 corresponds to the position of the button 5 on the circuit board 3 through the dome switch 8.

[0035] In order to ensure the sealing effect of the positions of the light guide column 7, the through hole 61, and the light-transmitting hole 51, in this embodiment, the upper light-transmitting part 72 is integrally frustum-shaped. The light-transmitting hole 51 of the button 5 and the through hole 61 of the silica gel pad 6 are tapered holes. When the upper light-transmitting part 72 is frustum-shaped and the through hole 61 of the silica gel pad 6 and the light-transmitting hole 51 are tapered holes, when the button 5 is pressed, the button 5 and the silica gel pad 6 act on the inclined surface of the upper light-transmitting part 72, so that the light guide column 7 moves downward. At the same time, it can also ensure better fitting of the positions of the button 5, the silica gel pad 6, and the upper light-transmitting part 72 of the light guide column 7, improving the waterproof effect of the button 5.

[0036] In another embodiment of the present invention, a remote control uses the above-mentioned light-transmitting button 5. At this time, a plurality of buttons 5 are provided. All the buttons 5 adopt the light-transmitting button 5 structure, or some of the buttons 5 adopt the light-transmitting structure and some adopt the ordinary structure.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0038] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
