Expansion device of remote controller

An expansion device of a remote controller comprises a shell and a control circuit module. The first end of the shell is provided with a containing cavity used for containing the remote controller, and the edge of the containing cavity is provided with one or more sets of buckle components; the second end of the shell is provided with a sealing cavity, and the control circuit module is located inthe sealing cavity; when the remote controller is placed in the containing cavity, the buckle part limits the remote controller. According to the scheme, multiple functions with large power consumption can be achieved through the expansion device, and the use cost of a user is reduced while the user requirement is better met. 一种遥控器的拓展装置，包括壳体以及控制电路模块；其中，所述壳体的第一端具有用于放置所述遥控器的容纳腔，所述容纳腔的边缘具有一组或多组卡扣部件；所述壳体的第二端具有密封腔，所述控制电路模块位于所述密封腔内；当所述遥控器放置于所述容纳腔时，所述卡扣部件对所述遥控器进行限位。本发明方案可以利用拓展装置实现多种功耗较大的功能，在更好地满足用户需求的同时，降低用户使用成本。
