Description

electronic devices This application claims priority to Chinese Patent Application No. 202411559837.X, filed with the State Intellectual Property Office of China on November 1, 2024, entitled “Electronic Device”, the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of electronic product technology, and more particularly to an electronic device. Background Technology Currently, electronic devices such as mobile phones and tablets are equipped with button modules to trigger one or more functions. For example, button modules can be used to control the power on/off of the electronic device, the screen power on/off, volume control, and camera control. However, button modules in this technology are prone to errors during assembly, affecting their reliability. Summary of the Invention This application provides an electronic device to solve the technical problem that button modules are easily assembled incorrectly during the assembly process. To achieve the above objectives, this application adopts the following technical solution: This application provides an electronic device, including a button body and a housing. The button body includes a pressing structure and a triggering structure. The pressing structure includes an outer surface, and the triggering structure is located on the side of the pressing structure opposite to the outer surface. The triggering structure includes a first segment and a second segment arranged in a first direction. The first segment is located between the pressing structure and the second segment. The second segment includes a first body portion and a buffer member, with the buffer member disposed at the end of the first body portion away from the first segment. The housing has a first connecting hole, and the second segment is disposed within the first connecting hole. The pressing structure is located outside the first connecting hole, and the first connecting hole includes a first opening facing the pressing structure. The first segment is projected orthographically onto a reference plane as a first projection, and the first opening is projected orthographically onto the reference plane as a second projection. The area of the first projection is larger than the area of the second projection. The reference plane is perpendicular to the first direction. In this way, when the trigger structure is assembled into the first connecting hole from the first opening with the second segment facing the pressing structure and the first segment facing the switch, the first segment of the trigger structure will be blocked outside the first opening or stuck inside the first connecting hole, making it impossible to assemble the trigger structure with the first connecting hole. Therefore, the first segment can form a foolproof structure for the trigger structure, allowing it to be detected in time when the trigger structure is assembled in the wrong orientation (i.e., the aforementioned second orientation), effectively preventing the trigger structure from being installed backwards and ensuring correct installation. This allows the buffer to be located at the end of the trigger structure furthest from the pressing structure, ensuring that the trigger structure can contact the switch with the help of the buffer to trigger the button module. This not only buffers the force between the first body and the switch, improving the pressing feel of the button body, but also helps prevent corrosion or swelling of the buffer, thus improving its reliability and effectively preventing switch failure, thereby improving the reliability of the button module. In one possible implementation, the first segment includes a first end face and a second end face facing away from each other. The second end face faces away from the pressing structure, and the orthographic projection of the second end face onto the reference plane is a third projection. At least a portion of the third projection does not overlap with the second projection. In this way, as the button body moves relative to the housing, the first segment remains outside the first connecting hole, effectively preventing the first segment from getting stuck in the first connecting hole. This ensures smooth switching between the initial position and the triggered position of the button body, preventing the button body from getting stuck. In one possible implementation, the first segment includes a first end face and a second end face facing away from each other, with the second end face facing away from the pressing structure. The area of the first end face is greater than or equal to the area of the second end face. This helps to ensure a larger contact area between the triggering structure and the pressing structure, thereby improving the stability of the fit between them and reducing the stress between them. This also helps to prevent damage to the pressing and triggering structures during compr
