Description

Anti-misinstallation push button fixing mechanism

technical field

The utility model relates to a push button fixing mechanism for preventing misinstallation, in more detail, relates to a push button fixing mechanism for preventing mistaken installation with the function of foolproofing during installation.

Background technique

In the current general-purpose electronic devices, such as electronic devices such as notebook computers (Notebook), portable DVD/VCD players (portable DVD/VCD player) and multimedia players (multimedia viewer), most of them will be provided with a push button (knob button). ), used to push or touch components inside its housing, such as switches, wireless modules, locking mechanisms, etc.

At the same time, in order to pursue the beauty of its appearance and the comfort of the handle, the current various electronic devices adopt a streamlined design for the casing, that is, slopes or rounded corners are set at the edges or corners, such as the Chinese Taiwan patent The invention patent No. 276946 in the certificate and the No. 564340 invention patent in the Taiwan Patent Announcement disclose related designs. Therefore, for operating elements such as exposed push buttons, in order to consider the convenience of their operation, the push buttons are usually designed in a trapezoidal shape, and a corresponding push button fixing mechanism is provided to combine the push button with the housing. In this way, the installed push button can conform to the slope of the casing without affecting the structural beauty of the overall appearance.

Taking the push button fixing mechanism of a notebook computer as an example, as shown in Figure 1A and Figure 1B, the push button fixing mechanism is applied to a casing 1 of a notebook computer. There is a card slot 10. The push button fixing mechanism includes a rectangular engaging hole 11 disposed in the engaging slot 10 , and the trapezoidal push button 2 can be used to combine with the rectangular engaging hole 11 . The inner surface 20 of the trapezoidal push button 2 has a hook 21 for passing through the rectangular hole 11, and a driving portion 23 provided on one side of the hook 21, and the hook 21 can be buckled to the housing. 1, the driving part 23 can drive the internal components (not shown) of the housing 1. After the normal assembly is completed, as shown in FIG. 1C , the installed push button 2 can follow the slope of the casing 1 .

However, in the actual production and assembly process, since the rectangular locking hole 11 and the hook 21 are symmetrical structures, the trapezoidal push button 2 can be fixed to the housing 1 no matter whether the assembler assembles in the correct direction or not. In other words, it is easy for the assembler to reversely install the trapezoidal push button 2 on the housing 1, as shown in FIG. The surface of the casing 1 affects the appearance.

Furthermore, since the push button is first fixed to the housing in the assembly process, and then other components are assembled, if you want to reinstall the wrongly installed push button, you must first disassemble the other components that have been installed, and then disassemble the push button. button and reinstall the push button, after which other components need to be assembled. It can be seen that the re-work (re-work) caused by wrong installation not only wastes working time, but also causes the originally weak shell or hook to break easily due to repeated disassembly and assembly, resulting in an increase in cost.

Therefore, how to design an anti-misinstallation push button fixing mechanism that can prevent misinstallation, so as to solve various defects in the above-mentioned prior art, is actually a problem to be solved urgently by operators in related fields.
