The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the singular forms "a", "an" and "the" include plural references unless the context clearly dictates otherwise. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0027] Reference will now be made to Figures 1 to 6The application discloses a replaceable key remote controller structure, which comprises a bottom shell 100, an ejector 200, a PCB board 300, an elastic lining 400, a light blocking ring 500, a key 600 and a face shell 700. The ejector 200 and the PCB board 300 are arranged on the bottom shell 100, and the ejector 200 is arranged below the PCB board 300. The elastic lining 400 is arranged on the PCB board 300. The face shell 700 is arranged on the bottom shell 100 and is provided with a key position through hole 710. The light blocking ring 500 and the key 600 are arranged in the key position through hole 710. The light blocking ring 500 is limited by the face shell 700. The key 600 is connected with the light blocking ring 500 and abuts against the elastic lining 400. The bottom of the ejector 200 is provided with a pressing column 210 which penetrates the bottom of the bottom shell 100. The top of the ejector 200 is provided with a lifting column 220 which penetrates the PCB board 300 and acts on the elastic lining 400, so that the key 600 is ejected.

[0028] Specifically, in the embodiment, the ejector 200, the PCB board 300 and the elastic lining 400 are sequentially arranged on the bottom shell 100 from bottom to top. The face shell 700 is arranged on the bottom shell 100. The light blocking ring 500 and the key 600 are arranged in the key position through hole 710 of the face shell 700. The light blocking ring 500 is limited by the face shell 700. The key 600 is connected with the light blocking ring 500 and abuts against the elastic lining 400, so that the remote controller structure is assembled. When the key 600 needs to be replaced, the pressing column 210 of the ejector 200 which penetrates the bottom of the bottom shell 100 is pressed, so that the ejector 200 is operated. When the ejector 200 is operated, the lifting column 220 at the top of the ejector 200 applies pressure to the elastic lining 400. Since the elastic lining 400 abuts against the key 600, when the elastic lining 400 is applied with pressure, the elastic lining 400 acts on the key 600 and ejects the key 600 from the key position through hole 710 of the face shell 700, so that the key 600 is separated from the light blocking ring 500. At this time, the new key 600 is arranged in the key position through hole 710 and connected with the light blocking ring 500, so that the key 600 is replaced. During the replacement of the key 600, only the pressing column 210 of the ejector 200 needs to be pressed, so that the replacement of the key 600 is simple and convenient. In addition, the key 600 is replaced alone, so that the maintenance cost is effectively reduced.

[0029] In order to enable the elastic inner lining 400 to apply pressure to the key 600 when the ejector 200 acts on the elastic inner lining 400, the elastic inner lining 400 in the embodiment has elastic protrusions 410 that cooperate with the key 600. The elastic protrusions 410 pass through the light-blocking ring 500 and abut against the key 600. The elastic inner lining 400 is made of silicone. When the pressing column 210 of the ejector 200 is pressed, the lifting column 220 of the ejector 200 is forced to apply pressure to the elastic protrusions 410 of the elastic inner lining 400. When the elastic protrusions 410 are subjected to pressure, they act on the key 600, thereby ejecting the key 600 from the keyhole through hole 710 of the face shell 700, so as to realize replacement of the key 600.

[0030] Further, in order to install the ejector 200, the bottom shell 100 is provided with a support portion 120 for installing the ejector 200. The ejector 200 is made of ABS plastic. In order to facilitate pressing of the pressing column 210 of the ejector 200 and enable the lifting column 220 of the ejector 200 to cooperate with the elastic inner lining 400, the bottom shell 100 is provided with a pressing hole 110 through which the pressing column 210 can pass out of the bottom shell 100, thereby enabling the pressing column 210 to be pressed. The PCB board 300 is provided with an avoiding hole 310 through which the lifting column 220 can pass through the PCB board 300 and cooperate with the elastic inner lining 400. In this way, the elastic protrusions 410 of the elastic inner lining 400 are pressed by the lifting column 220, so as to eject the key 600.

[0031] In addition, please refer to Figures 2 to 4 Since the remote controller in the embodiment is a backlit remote controller, the key 600 can emit light in a dark environment, so that the characters on the key 600 can be clearly seen. Since the key 600 of the remote controller is detachably replaceable, the assembly gap between the key 600 and the keyhole through hole 710 is large, thereby causing the key 600 to be translucent around the keyhole through hole 710, which affects the clarity of the characters on the key 600 when the key 600 is backlit. Therefore, the light-blocking ring 500 is installed in the keyhole through hole 710. The light-blocking ring 500 can block the gap, thereby preventing the key 600 from being translucent around the keyhole through hole 710, so as to facilitate observation of the characters on the key 600 and use of the remote controller.

[0032] In order to install the light blocking ring 500, a limiting part 510 is arranged at the bottom edge of the light blocking ring 500, when the face cover 700 is combined with the bottom cover 100, the face cover 700 can limit the installation of the light blocking ring 500 at the edge in the key position through hole 710 through the limiting part 510, at this time, the key 600 is also installed in the key position through hole 710, and is connected with the light blocking ring 500, so that the installation of the light blocking ring 500 is realized, and the light blocking ring 500 can shield the light around the key 600, so as to facilitate the use of the remote controller.

[0033] Meanwhile, in order to facilitate the connection of the key 600 and the light blocking ring 500, in the embodiment, the inner wall of the light blocking ring 500 is provided with a clamping groove 520, and the outer wall of the key 600 is provided with a clamping block 610 corresponding to the clamping groove 520, when the key 600 is connected with the light blocking ring 500, the clamping block 610 of the key 600 is clamped into the clamping groove 520 of the light blocking ring 500, so that the key 600 and the light blocking ring 500 are clamped, and the key 600 is installed in the key position through hole 710; when the pressing column 210 of the ejector 200 is pressed, the lifting column 220 of the ejector 200 exerts pressure on the elastic protrusion 410 of the elastic lining 400, and the elastic protrusion 410 of the elastic lining 400 exerts pressure on the key 600, so that the clamping block 610 of the key 600 is separated from the clamping groove 520 of the light blocking ring 500, so that the key 600 is ejected from the key position through hole 710, and the key 600 is replaced.

[0034] Finally, the remote controller has a plurality of keys 600 in the embodiment, and the elastic lining 400 has a plurality of elastic protrusions 410, and the pressing column 210 and the lifting column 220 of the ejector 200 also have a plurality of, and the key 600, the elastic protrusion 410, the pressing column 210 and the lifting column 220 correspond one by one, so that each key 600 on the remote controller can be individually ejected and replaced through a plurality of groups of pressing columns 210, lifting columns 220 and elastic protrusions 410, so as to reduce the subsequent maintenance cost.

[0035] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. Any person skilled in the art can implement the utility model according to the drawings and the above description; however, any equivalent changes, modifications and evolution made by any person skilled in the art within the scope of the technical scheme of the utility model, using the above disclosed technical content, are equivalent embodiments of the utility model; meanwhile, any equivalent changes, modifications and evolution made by any person skilled in the art according to the essential technology of the utility model are still within the protection scope of the technical scheme of the utility model.
