Description
Technical field
This utility model relates to technique for fixing, particularly relates to the fixing device of a kind of pressure touch module.
Background technology
Traditional key switch (as mobile phone physical button switchs) is mainly made up of three parts: the button cover that is embedded in phone housing, button self, the key supporting structure that is embedded in mainboard supporting construction. Button cover be stressed tailing edge vertical hand machine side casings direction produce point to interior of mobile phone displacement, extruding button contact point. After keyboard contact point is squeezed, end metal sheet Guan Bi circuit, coupling cock circuit. After system detects the signal of telecommunication of on-off circuit, identify button and be pressed.
Due to the stress point that button self needs only to, contact point for button cover Yu button, extruding the contact point of this button just can coupling cock circuit, and except this on-off circuit, without the signal processing circuit of additional complexity, therefore, the circuit realiration principle of above-mentioned key switch is simple, structure is also simple, is widely used. Adopt the fixed form of conventional keys, it is the side that described key supporting structure is embedded in described mainboard supporting construction, when button is installed, is aligned with the gap of phone housing and internal main board supporting structure, pressing is inserted, and connects the interface of button and cell phone mainboard.
Novel key switch (by the pressure buttons switch that pressure touch module realizes) mainly is made up of two parts: button self structure, fix the supporting construction of button. Pressure touch module changes the associated electrical signals in pressure touch modular circuit because of deformation, and this signal of telecommunication, after special signal processing integrated circuit plate (IC) circuit and algorithm process, is identified as different button operations. Last signal processing circuit will identify that the different button operation obtained passes to system, and system performs different process according to different button operations.
For novel key switch, this pressure buttons switch realized by pressure touch module, owing to pressure buttons switch by independent signal processing IC circuit and a piece of can not be formed by the described pressure sensitive film that handset structure affects, this novel key switch is compared to traditional key switch, and the structure relative complex of its button self is many.
In sum, novel key switch is due to the complexity of its pressure buttons structure self, the more traditional key switch of thickness adds much, and installing, in order to eliminate the handset structure impact on pressure sensitive film, except the supporting construction of self, remaining part can not produce any interaction force with phone housing or mainboard supporting construction. If it occur that interaction force, so, after the specific region that phone housing button position is corresponding is under pressure, the associated electrical signals in pressure touch modular circuit is changed because producing deformation, the described different button operation that this signal of telecommunication finally identifies after special signal processing IC circuit and algorithm process can identify inaccurate, thus causing that function problem occurs in novel key switch.
Visible, if still realizing fixing novel key switch with the fixed form switched for conventional keys, owing to the interaction force that button back and cell phone mainboard occur between supporting when button pressurized cannot be avoided, therefore, the normal operation of pressure sensitive film can be affected, thus causing that function problem occurs in described novel key switch. In order to make novel key switch energy normal operation, it is necessary to design new keystroke fixing structure.

Pressure touch module A 1, the pressure sensitive film of its front portion is contacted with each other by double faced adhesive tape and phone housing 21, to sense the pressure from phone housing 21. Pressure touch module A 1, the signal processing IC circuit at its back is attached in the supporting construction of self with the form of FPCA chip 14, is in unsettled form, to avoid affecting the normal operation of pressure sensitive film group with other form touch of mobile phone. Wherein, when an example of signal processing IC circuit realizes with the form of FPCA chip 14, the holding wire of FPCA chip 14 is along the trough layout of described mainboard supporting construction, and is ultimately connected to the signaling interface 15 of motherboard circuit.
In this utility model one embodiment, draw-in groove 17 includes L-type baffle plate, one end of baffle plate is connected to the inner surface of phone housing 21, the other end of baffle plate is parallel with the inner surface of phone housing 21, therefore baffle plate and phone housing are collectively forming an accepting groove, accepting groove has two openings, and one of them opening is relative with another draw-in groove, and another card channel opening is upward.Accepting groove has 2, respectively the first accepting groove 191 in Fig. 2 and shown in the second accepting groove 192, and wherein, the first accepting groove 191 is relative with the first buckle 161 in Fig. 2, is the groove of the first buckle 161 upwards two sides opening to the right below; Second accepting groove 192 is relative with the second buckle 162 in Fig. 2, is the groove of the second buckle 162 upwards two sides opening to the left below, is cooperatively made up of a part for described draw-in groove the first accepting groove 191 and the second accepting groove 192 the two accepting groove.
In this utility model one embodiment, two buckles (first buckle 161 and the second buckle 162) are hollow outs in the middle of, the cuboid laminated structure of three openings. Three openings form a simple accepting groove, for housing the supporting construction of pressure touch module A 1. During installation, left-hand thread, in the supporting construction of pressure touch module A 1, is fixed on the two ends of draw-in groove 17.
In this utility model one embodiment, trough (not shown) along mainboard supporting construction layout, it is the depression fillet L row narrow slot on mainboard supporting construction surface, exports the line of signaling interface and the signaling interface 15 of motherboard circuit for pressure touch module A 1.
Based on the description of above-mentioned this utility model and various embodiment thereof, in actual applications, applying the fixing device of pressure touch module of the present utility model, its installation process includes following content:
First pressure touch module A 1 is inserted in draw-in groove 17, the foam in pressure touch module A 1 is made to be close to the inner surface of phone housing 21, then buckle (first buckle 161 and the second buckle 162) is inserted in draw-in groove 17 along the opening of accepting groove (first accepting groove 191 and the second accepting groove 192), and make the snap fit of buckle (first buckle 161 and the second buckle 162) be mutually clamped with the interface of setting on draw-in groove 17, so that buckle (first buckle 161 and the second buckle 162) and draw-in groove 17 fit together. When one example of signal processing IC circuit realizes with the form of FPCA chip 14, the output signal line of FPCA chip 14 is good along trough layout, the supporting construction of comparison mainboard installs cell phone mainboard, is finally connected with the signaling interface 15 of motherboard circuit by the holding wire of FPCA chip 14.
Adopt this utility model, eliminate the button cover of conventional physical button, touch phone housing correspondence position and can trigger pressure touch module, thus realizing key switch function, it is provided that brand-new key user is experienced. The design that this utility model provides is also more flexible than the fixing device of traditional physical button, the shortcoming that conventional physical press key fixing device is applied can not only be avoided in novel buttons field, and, can not only be applied to novel buttons field, simultaneously can also compatible conventional keys field, namely can also be applied to fixing with the conventional physical key switch supported.
