Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the template herein is only for the purpose of describing specific embodiments and is not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0044] As Figures 1 to 3 Some embodiments of the present application provide a key, which includes a control board 100, a plurality of spaced apart light emitting modules 200, at least one key switch 300 and a key shell 400.

[0045] Among them, the number of light emitting modules 200 can be two or any number of values, which can be set according to actual conditions. In addition, the number of key switches 300 can be one, two or any number of values.

[0046] In addition, the light emitting module 200 can be an LED light emitting module 200.

[0047] Meanwhile, each of the key switch 300 and each of the light-emitting module 200 are arranged on the control panel 100 respectively and are electrically connected with the control panel 100 respectively, so as to control the light-emitting module 200 to be lighted or extinguished through the control panel 100.

[0048] In addition, the control panel 100 is provided with a key shell 400, and the key shell 400 is provided with at least one key cap 410, and each of the key cap 410 covers one of the key switch 300, and it is to be noted that the inner wall of the key cap 410 is spaced apart from the key switch 300, so that the light-emitting space is formed through the combination of the key cap 410 and the control panel 100.

[0049] The side wall of each of the key cap 410 is provided with a light shielding layer, and it is to be noted that the side wall of the key cap 410 refers to the inner side wall of the key cap 410 or the outer side wall of the key cap 410. It can be understood that the light shielding layer is not arranged on the top surface of the key cap 410, and at least one light-emitting module 200 is arranged on the inner side of each of the key cap 410, so that the light emitted by the light-emitting module 200 can pass through the top surface of the key cap 410, so that the user can observe the light-emitting key cap 410, so as to facilitate the user to control the key switch 300.

[0050] It is to be noted that, in order to avoid the light emitted by the light-emitting module 200 located in the inner side of the key cap 410 from being transmitted from the side wall of the key cap 410, which forms interference to the key cap 410 which has not been lighted yet and affects the judgment of the user, the light shielding layer is arranged on the side wall of the key cap 410, so as to block or shield the light emitted by the light-emitting module 200 located in the inner side of the key cap 410, and meanwhile, the light interference phenomenon of the adjacent key cap 410 in the light-emitting process can be avoided.

[0051] Among them, the light interference mainly has two cases: overflow light interference and glare interference. The overflow light interference is that the adjacent direct light or reflected light exceeds the range that should be lighted originally, and the phenomenon that other things are lighted; the glare interference mainly comes from the direct vision of dazzling light, because it is difficult to avoid the attraction of light to attention, so as to disturb the normal attention object.

[0052] In some embodiments of the present application, the number of the key switch 300 and the number of the key cap 410 are multiple respectively and are equal, and a plurality of the light-emitting module 200 are arranged on the circumference of each of the key switch 300 respectively.

[0053] Among them, the arrangement mode of the plurality of light-emitting modules 200 arranged on the circumference of the key switch 300 can be any one of the annular arrangement, the broken line arrangement and the array or the combination of two or more.

[0054] As Figure 3As shown in the drawings, in some embodiments of the present application, the number of key switches 300 and the number of keycaps 410 are both two, i.e. the keycap 410 is arranged on the key shell 400 in two, and the two keycaps 410 are arranged at intervals.

[0055] Specifically, the plurality of light-emitting modules 200 are arranged in a ring around the keycap 410, and the spacing between any two adjacent light-emitting modules 200 is equal. In addition, in order to improve the coverage area of the light emitted by the light-emitting module 200, there is a gap between each light-emitting module 200 and the keycap 410, and there is a gap between each light-emitting module 200 and the key switch 300.

[0056] It can be understood that by arranging the light shielding layer on the side wall of each keycap 410, the phenomenon of light interference between adjacent two keycaps 410 can be avoided, and the collimation of the light emitted by each light-emitting module 200 through the keycap 410 can be improved.

[0057] At the same time, by arranging the light shielding layer on the side wall of the keycap 410, the scattering of light can be avoided when the light emitted by the light-emitting module 200 transmits through the keycap 410. It should be noted that the scattering of light refers to the phenomenon that part of the light deviates from the original direction when the light passes through a non-uniform medium. The light deviating from the original direction is called scattered light. The scattering light does not change the frequency, such as Dingtuoer scattering (Dingdah effect), molecular scattering; the frequency changes, such as Raman scattering, Brillouin scattering and Compton scattering. Dingtuoer scattering was first studied by J. Dingtuoer, which is caused by suspended particles in a homogeneous medium (such as smoke and dust in the air), turbidity liquid and colloid. True solution does not produce Dingtuoer scattering, and chemistry often distinguishes colloid and true solution according to whether there is Dingtuoer scattering. Molecular scattering is caused by density fluctuations caused by molecular thermal motion. The scattering with changed frequency is related to the microstructure of the scattering substance.

[0058] As shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, in some embodiments of the present application, the side of the key shell 400 away from the control panel 100 is provided with a cover 500, and the cover 500 is provided with at least one key part 510. The number of key parts 510 is equal to the number of key switches 300, and each key part 510 covers one key switch 300.

[0059] Specifically, each key part 510 covers one key switch 300 means that in the orthographic projection of the plane where the control panel 100 is located, the plane formed by the key part 510 in the projection direction covers the plane formed by the key switch 300 in the projection direction.

[0060] It should be noted that, in order to further improve the collimation of light in the keycap, a light-shielding layer is coated around the outer wall of the keycap. This layer blocks the light inside the keycap, preventing the light from being transmitted through the side wall.

[0061] In addition, in some embodiments of the present invention, a light-shielding layer is provided on the side wall of the cover 500 to block and shield the light emitted by the light-emitting film, so as to further improve the collimation of the light emitted by the light-emitting module 200 transmitted through the keycap 410 and prevent light interference.

[0062] It should be noted that the light-shielding layer can be any one of PS (Polystyrene), PVC (Polyvinylchloride), PE (polyethylene), or PP (polypropylene). Alternatively, the light-shielding layer can also be a light-shielding coating, which is formed by adding light-shielding agents such as titanium dioxide, carbon black, and pigments to a coating agent and then applying multiple layers. When light strikes the light-shielding coating, it is either reflected or absorbed and ultimately completely blocked, thus achieving the purpose of light shading.

[0063] The color of the light-shielding layer can be specifically set according to the actual situation. Specifically, in this embodiment, the color of the light-shielding layer is black to improve the quality of blocking the light emitted by the light-emitting module 200.

[0064] In some embodiments of the present invention, both the cover 500 and the keycap 410 are made of light-transmitting material, and the color of the cover 500 can be any one or a combination of two or more of red, orange, yellow, green, cyan, blue, and purple.

[0065] It should be noted that the cover 500 and keycap 410 can be made of materials such as glass, plexiglass, acrylic sheet, polycarbonate sheet, translucent stone, and translucent resin.

[0066] In addition, the cover 500 and keycap 410 are made of soft material, allowing users to press the cover 500 and keycap 410 to press the key switch 300.

[0067] like Figure 3 As shown, in some embodiments of the present invention, a data interface 600 is provided on the side of the control board 100 opposite to the push button switch 300, so that an external power supply or mobile terminal can form an electrical connection with the data interface 600 through a data cable to control the push button switch 300.

[0068] In addition, such as Figures 4 to 6 As shown, some embodiments of the present invention provide a button, the button further including a light-transmitting plate 700.

[0069] It should be noted that the light-transmitting plate 700 is a ring structure with a middle passage, and the light-transmitting plate 700 is sleeved on the cover body 500, and the light-transmitting plate 700 is connected with the edge of the key shell 400. The connection between the light-transmitting plate 700 and the key shell 400 can be any one of clamping, bonding, threaded connection, bolt connection, or a combination of two or more thereof.

[0070] Specifically, the light-transmitting plate 700 completely covers the side wall of the cover body 500.

[0071] In order to avoid the light emitted by the light-emitting module 200 inside the keycap 410 interfering with the light-transmitting plate 700, the side wall of the cover body 500 is provided with the light-blocking layer, which can block the light emitted by the light-emitting module 200 inside the keycap 410.

[0072] It should be noted that the side wall of the cover body 500 refers to the inner side wall of the cover body 500 and / or the outer side wall of the cover body 500. Specifically, the outer surface of the cover body 500 is coated with the light-blocking layer 1000, and the key portion 510 of the cover body 500 is not coated with the light-blocking layer 1000, so that the light emitted by the light-emitting module 200 inside the keycap 410 is projected from the key portion 510 of the cover body 500, thereby improving the collimation of the light emitted from the inside of the keycap.

[0073] Preferably, the light-blocking layer 1000 is arranged on the outer side of the side wall of the cover body 500.

[0074] In addition, by coating the inner wall of the mounting groove 420 with the light-blocking layer 1000, the light-blocking layer 1000 blocks the light passing through the key shell 400, thereby avoiding mutual interference between the light emitted by the light-emitting module in the cavity and the light emitted by the light-emitting module inside the keycap.

[0075] Specifically, the light-transmitting plate 700, the key shell 400, and the control panel 100 form a cavity 800, and a plurality of spaced-apart light-emitting modules 200 are arranged in the cavity 800. The arrangement of the plurality of light-emitting modules 200 in the cavity 800 can be any one of a ring arrangement, an array, or a zigzag arrangement, or a combination of two or more thereof.

[0076] It can be understood that when the light-emitting module 200 is arranged in the cavity 800 and the light-emitting module 200 is electrically connected with the external power supply, the light-emitting module 200 can emit light, and the light emitted by the light-emitting module 200 in the cavity 800 can transmit through the light-transmitting plate 700, thereby illuminating the light-transmitting plate 700.

[0077] In addition, in some embodiments of the present application, the light-shielding layer is arranged on the side of the light-transmitting plate 700 facing the cover 500, and the light emitted by the light-emitting module 200 in the cavity 800 is blocked by the light-shielding layer, so as to avoid the light emitted by the light-emitting module 200 in the cavity 800 from being transmitted into the keycap 410 and interfering with the light emitted by the light-emitting module 200 in the keycap 410.

[0078] It should be noted that the side light source of the key is uniformly transmitted through the light-transmitting plate 700.

[0079] As shown in Figure 6 some embodiments of the present application, in order to further improve the collimation of the light emitted by the light-emitting module 200 and transmitted from the keycap 410 and the light-transmitting plate 700, and avoid light interference, the light-shielding layer is arranged on the side of the key housing 400 away from the key switch 300. It can be understood that the light-emitting module 200 in the keycap 410 is blocked and shielded from the light-emitting module 200 in the cavity 800 by the arrangement of the light-shielding layer, which avoids the light emitted by the light-emitting module 200 in the keycap 410 from being transmitted through the edge of the key housing 400 into the cavity 800, and also avoids the light emitted by the light-emitting module 200 in the cavity 800 from being transmitted through the edge of the key housing 400 into the keycap 410, thereby avoiding the phenomenon of light interference.

[0080] As shown in Figure 1 , Figure 4 and Figure 6 some embodiments of the present application, in order to improve the stability of the connection between the key housing 400 and the light-transmitting plate 700, the mounting groove 420 is arranged on the edge of the key housing 400, the light-transmitting plate 700 is provided with the protrusion 710 on the side facing the control panel 100, and the protrusion 710 is engaged with the mounting groove 420.

[0081] It should be noted that in order to make the light transmitted through the silicone protrusion on the side of the mounting groove 420 close to the keycap 410 and transmitted through the light-transmitting plate 700, the light-shielding layer 1000 is coated on the inner wall of the mounting groove 420. The light-shielding layer 1000 blocks the light passing through the key housing 400, preventing the light from being transmitted out of the mounting groove, so that the light can be transmitted into the light-transmitting plate through the protrusion on the side of the mounting groove close to the keycap, and the light-transmitting plate is illuminated.

[0082] Further, the light-shielding layer 1000 is coated on the side of the light-transmitting plate 700 close to the keycap 410, and the light-shielding layer 1000 is also coated on the side of the light-transmitting plate 700 away from the keycap 410, so as to avoid the light entering the light-transmitting plate from leaking out of the side wall of the light-transmitting plate, thereby improving the collimation of the light when it is transmitted through the light-transmitting plate.

[0083] In addition, the light-transmitting plate 700 and the key shell 400 can also be connected by adhesive to further improve the stability of the connection between the light-transmitting plate 700 and the key shell 400.

[0084] The material of the translucent panel 700 can also be glass, plexiglass, acrylic sheet, polycarbonate sheet, translucent stone, translucent resin, etc.

[0085] It should be noted that the color of the light-transmitting panel 700 is different from the color of the housing 900, in order to facilitate color differentiation.

[0086] like Figure 7 and Figure 8 As shown, some embodiments of the present invention provide a housing, including a housing 900 and a button as described in any of the above embodiments, the button being disposed on the housing 900.

[0087] Specifically, the housing 900 has an installation opening, and the light-transmitting plate 700 abuts against the inner wall of the installation opening. At the same time, the control plate 100 is connected to the housing 900 by bolts, so that the control plate 100 and the housing 900 limit the light-transmitting plate 700, the cover 500 and the key shell 400 to improve the stability of the key on the housing 900.

[0088] In addition, in some embodiments of the present invention, the connection between the button and the housing 900 can be embedded installation, that is, the button is embedded in the housing 900.

[0089] Some embodiments of the present invention also provide an electronic device, such as a robotic vacuum cleaner, including a main control board and a housing 900 as described in any of the above embodiments.

[0090] The main control board is electrically connected to the control board 100 so that the main control board can send control commands to the control board 100 and the control board 100 can control the starting or stopping of the light-emitting module 200.

[0091] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0092] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0093] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the protection scope of the present application.
