detailed description

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

detailed description

1 to 4 are respectively an exploded sectional view, an exploded view, an assembly sectional view and a partially enlarged view of the hidden display touch key structure in this embodiment. As shown in FIG. 1 to FIG. 4 , this embodiment proposes a hidden display touch button structure, which can be applied to a rice cooker. The hidden display touch button structure includes a transparent shell 1, a pattern layer 2 and a PCB board 3 arranged in the transparent shell 1, a lampshade bracket 5 is arranged between the transparent shell 1 and the PCB board 3, and the pattern layer 2 is arranged on the lampshade. on the surface of the bracket 5.

On the basis of the existing hidden display touch button structure, the utility model arranges the pattern layer 2 on the surface of the lampshade bracket 5, which not only can realize touch control, but also can display hiddenly (it can clearly display text or / and patterns, text or/and patterns cannot be clearly displayed after power off), which effectively solves the limitation problem that the existing appearance parts cannot use IMD technology, and there is no limit to the appearance shape of the appearance parts.

This embodiment proposes a preferred hidden display touch button structure, which includes a transparent shell 1, a pattern layer 2 and a PCB board 3 arranged in the transparent shell 1, and a lampshade bracket is arranged between the transparent shell 1 and the PCB board 3 5. Specifically, the transparent housing 1 is injection-molded with a transparent material, and a sprayed layer is provided on the surface of the transparent material. The transparent shell 1 is provided with a key display area 6 (see FIG. 2 ) for displaying keys. The key display area 6 is at least partly thinned to clearly display text or patterns when the keys are illuminated. The lampshade bracket 5 is closely attached to the transparent shell 1 and the two are fastened and connected by screws, and the PCB board 3 and the lampshade bracket 5 are fastened and connected by screws. In this way, the lampshade bracket 5 can be assembled on the assembly line, which is convenient for assembly and does not require overtime. wave soldering.

In this embodiment, the pattern layer 2 is disposed on the surface of the lampshade support 5 . Preferably, the pattern layer 2 is pasted on the surface of the lampshade bracket 5 with its own 3M glue, which is convenient to operate, realizes both touch control and hidden display, and effectively solves the limitation that the existing appearance parts cannot use IMD technology There are no restrictions on the appearance and shape of appearance parts.

The pattern layer 2 is a transparent film with characters and/or patterns printed on silk screen. Further, the silk screen on the pattern layer 2 is hollowed-out characters or/and patterns, and the characters or/and patterns are partly transparent and can transmit light, while other parts are opaque.

The PCB 3 is provided with an elastic component 32 , and one end of the elastic component 32 is connected to the sensing electrode of the PCB 3 , and the other end is in contact with the lampshade bracket 5 . Specifically, the elastic member 32 is an induction spring, and the induction spring is arranged between the lampshade support 5 and the PCB board 3 in a compressed form, so as to prevent the capacitance from being reduced due to the gap between the induction spring and the lampshade support 5, A problem with reduced touch sensitivity.

The PCB board 3 is provided with a light emitting diode 31 , the lampshade 4 is installed on the lampshade bracket 5 , and the light emitting diode is located in the lampshade 4 . Through the setting of the lampshade 4, the light emitted by the light-emitting diode 31 has a better light-gathering effect. Furthermore, the lampshade 4 is trumpet-shaped, and the bell mouth is far away from the light-emitting diodes 31. The lampshade 4 can better gather the light emitted by the light-emitting diodes 31, and has a guiding function to make the light display more uniform.

The above-mentioned elastic member 32 is sheathed outside the lampshade 4 . This kind of setting form can play a certain supporting and fixing effect on the elastic component 32 , and more importantly, it can make the button display area 6 and the elastic component 32 be located on the same straight line, which improves the accuracy of the button.

This embodiment also proposes a household appliance, which has the hidden display touch key structure as described above. For example, the hidden display touch button structure can be applied to not limited to household appliances such as rice cookers.

The technical principles of the present utility model have been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the utility model, and cannot be construed as limiting the protection scope of the utility model in any way. Based on the explanations herein, those skilled in the art can think of other specific implementation modes of the present utility model without creative work, and these modes will all fall within the protection scope of the present utility model.
