Description

A kind of depressible integral type touch key-press structure

Technical field

The utility model relates to vehicle mounted multimedia hosts to assemble field, in particular to a kind of depressible integral type touch is pressed Bond structure.

Background technique

The key form majority of existing vehicle-mounted automobile electronics in the market can be divided into physical mechanical key and touch key-press.And One module to realize multiple functions triggering we would generally assign its multiple physical mechanical key or the cloth on a plate Set multiple touch key-press.But there are many limited cases in reality again, for example physical mechanical press-key structure is complicated, space accounting is big, Since so much physical mechanical key is not arranged in space limitation, and the technology sense of physical button is not strong.But it uses and touches It is expensive since touch key-press need to be accompanied by feedback mechanism, mostly vibration and sound feedback when key, because cost limits It cannot consider the feedback mechanism of vibration with sound, and once be accounted for using conventional vibration or sound feedback module, space Than can also greatly increase.

Summary of the invention

In order to solve the above-mentioned technical problem the utility model, provides a kind of depressible integral type touch key-press structure.

A kind of depressible integral type touch key-press structure, including key, touch modules, trigger switch and identification are single The inside of the key-top is arranged in member, the touch modules, receives key press operation, and the trigger switch is arranged in institute Key bottom is stated, the pressing operation of the key is responded；The enabled input terminal of the recognition unit is arranged in the trigger switch Between enable signal source, the output end of the touch modules is connect with the input terminal of the recognition unit.

Further, the key includes button cap and key support, and the button cap is connected to the key support Top, the key support resist the trigger switch.

It further, further include pcb board, the trigger switch and recognition unit are welded on the pcb board.

Further, the touch modules are electrically connected with the pcb board by FPC wiring board, and the FPC wiring board is along institute State the distribution of key support inner sidewall.

Further, the key support setting.

Further, the key cap surface is equipped with different function character functional characters.

Further, touch modules are included in each function character functional character corresponding position and are provided with individual identification region.

A kind of depressible integral type touch key-press structure of the utility model plays following technical effect：

1, more keys can be thus achieved by key and touch modules cooperation in the complex degree of structure for optimizing mechanical key Trigger Function；

2, the unexistent key force feedback of conventional touch key is provided, the module arrangement of vibration, sound feedback is saved, is saved Cost and space.

Detailed description of the invention

Fig. 1 is the structural blast schematic diagram in the utility model embodiment 1.

Fig. 2 is the circuit module schematic diagram in the utility model embodiment 1.

Wherein, key 1；Button cap is 11；Key support is 12；Touch modules are 2；FPC wiring board is 21；Triggering Switch is 3；Recognition unit is 4；Pcb board is 5；Signal input part is INPUT；Enabled input terminal is EN.

Specific embodiment

The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model It is easier to be readily appreciated by one skilled in the art with feature, to make apparent define to the protection scope of the utility model.

Embodiment 1：

As depicted in figs. 1 and 2, the depressible integral type touch key-press structure of the utility model passes through touch-control module reality While existing button operation input, the feedback of mechanical key can also be realized.

Specifically, the press-key structure of the present embodiment is roughly the same with the key arrangement of the prior art in terms of setting, It can be embedded on the control panel, also can be set on knob.It, can be effective when its use is on automobile control panel Play the effect that feedback is reminded.It includes key 1, touch modules 2, trigger switch 3 and recognition unit 4.

Touch modules 2 can with but be not limited only to be resistive touch module or capacitance touch module.It is used to receive The pressing operation of key 1.The inside at 1 top of key preferably can be set in touch modules 2, according to 2 type of touch modules Difference can choose between key 1 by being bonded or being fixed by fixed structure, it is made to effectively receive touch-control behaviour Work.

1 aspect of key, key include button cap 11 and key support 12, the key hole of key support 12 and panel setting （Attached drawing is not shown）Match, makes user when implementing pressing operation, key 1 has the effect of crumple.Button cap 11 and touch mould Block 2 connects, and shape can need to be arranged to various shape according to different designs, and key support 12 is then suitable with button cap 11 Match, key support 12 is tubular structure, and top is connect with button cap 11, and bottom end is then against in trigger switch 3, in crumple Trigger switch 3 can in the process triggered.During user presses the button 1, trigger switch 3 can generate machinery in triggering Feedback guarantees to inform that user's operation is effective.

Preferably, the trigger switch 3 of the present embodiment is microswitch.In order to facilitate structure design, the setting of pcb board 5 is being pressed The bottom of bond structure, trigger switch 3 are welded on pcb board, meanwhile, the touch modules 2 of the present embodiment are to touch diaphragm, are passed through FPC wiring board 21 is electrically connected with the realization of pcb board 5, guarantees that touch signal can transmit, FPC wiring board 21 is along key support 12 Inner sidewall distribution, improve the compactedness of structure.

In terms of circuit structure, as shown in Fig. 2, signal caused by the button operation of user mainly have recognition unit 4 into Row identification is also improved, recognition unit 4 includes that signal is defeated due to increasing the machine feedback of trigger switch 3 on circuit Enter to hold INPUT, for receiving the signal of the output of touch modules 2, while further including enabled input terminal EN, when enabled input terminal EN connects When receiving enable signal, recognition unit 4 can just receive and identify the signal of touch modules 2.In the present embodiment, trigger switch 3 is set It sets between the enabled input terminal EN of the recognition unit and enable signal source, enable signal source can be high level signal, It can be provided by low-voltage regulated power supply.

In actual use, user touches operation to key 1 merely and can't be responded, and only presses the button 1 And make just to have corresponding response after the triggering of trigger switch 3, this function especially can effectively avoid missing when driving Touching, and user can significantly know whether button operation is effective under the action of trigger switch 3.

Further, since key 1 is touch key, different function words can be equipped on 11 surface of button cap Symbol, and each function character functional character corresponding position is provided with individual identification region in touch modules 2, when user presses corresponding function When energy character, touch modules 2 send corresponding signal specific to recognition unit, so that system implements corresponding response action.

The embodiments of the present invention is explained in detail above in conjunction with attached drawing, but the utility model is not limited to Above embodiment can also not depart from the utility model within the knowledge of a person skilled in the art Various changes can be made under the premise of objective.
