Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The terminal device provided in the related art employs a mechanical key. Generally, an opening is provided in a terminal housing of a terminal device, and a key includes a movable member inserted into the opening. When the terminal device is used, one end of the movable piece is positioned in the terminal device and is opposite to the contact of the circuit board; the other end of the movable piece extends out of the terminal through an opening on the terminal shell. The movable piece moves towards the inside of the terminal by pressing the part of the movable piece, which is positioned outside the terminal, until the movable piece contacts with the contact on the circuit board, and then an electric signal is output.

In addition, the terminal key in the related art is also provided with a reset piece arranged in the terminal equipment, so that a reset acting force is provided for the moving piece, and the moving piece is reset after the moving piece is released from abutting, so that the next operation can be performed.

The inventors found that the terminal provided in the related art has the following drawbacks:

first, need the trompil in order to peg graft the moving part on the terminal housing to the moving part needs to follow trompil axial activity, causes to have the gap between moving part and the trompil. The opening hole communicates the inside and the outside of the terminal, and affects the sealing property and the waterproof property of the terminal. Moreover, the opening of the holes in the terminal housing increases the process and manufacturing difficulty.

Secondly, enough space needs to be reserved in the terminal to install the key so as to meet the space requirement for triggering and resetting the moving part.

And thirdly, the keys are easy to damage and age in the frequent pressing and resetting processes, so that the service life of the terminal equipment is influenced.

Based on the above problem, the embodiments of the present disclosure provide a terminal and a terminal control method.

In a first aspect, an embodiment of the present disclosure provides a terminal. As shown in fig. 1 and 2, the terminal includes a terminal housing 10.

In one embodiment, the terminal housing 10 includes a rear cover 11 and sides 12. The side edges 12 are connected to the edges of the rear cover 11 to enclose a cavity 13. Optionally, the rear cover 11 and the side 12 are of an integrally formed structure. Alternatively, the rear cover 11 and the side 12 are two independent sets of members, and the connection is achieved by a connecting member (e.g., a screw, etc.) or a connecting structure (e.g., a key-groove structure, etc.).

Wherein the terminal housing 10 is provided with a pressing surface 14. Illustratively, the pressing surface 14 is disposed on the side edge 12, as shown in fig. 1, or the pressing surface 14 spans the rear cover 11 and the side edge 12, or, as shown in fig. 2, the pressing surface 14 is disposed on the rear cover 11. For the convenience of the user, a pressing surface 14 is provided on the outer side surface of the terminal housing 10.

Further, the terminal also comprises a first piezoelectric element 20, the first piezoelectric element 20 being located inside the terminal housing 10, i.e. within the cavity 13. The first piezoelectric element 20 is connected to the terminal housing 10, and the pressing surface 14 is pressed to deform the first piezoelectric element 20 and output an electrical signal.

Free electrons are adsorbed on the surface of the first piezoelectric element 20, and the piezoelectric effect is achieved, so that conversion between mechanical energy and electric energy is achieved.

As shown in fig. 3, when the first piezoelectric element 20 is compressed and deformed (from the state a to the state B shown in the figure), the first piezoelectric element 20 releases electrons, outputs an electrical signal, and realizes conversion from mechanical energy to electrical energy. Moreover, the sensitivity of the piezoelectric element to mechanical energy is high, and weak machinery can trigger the piezoelectric element to deform to generate a piezoelectric effect.

When the pressing of the first piezoelectric element 20 is released (from the state B to the state a shown in the figure), the first piezoelectric element 20 is deformed and restored, and the release of electrons is stopped, and the electric signal is no longer output.

As shown in fig. 4, when an external electric field acts on the first piezoelectric element 20, the first piezoelectric element 20 is deformed (switching between the a state and the B state), and conversion from electric energy to mechanical energy is performed. Among them, the piezoelectric element can realize a contraction deformation (from state a to state B), and an extension deformation (from state B to state a). The deformation mode and degree of the first piezoelectric element 20 can be controlled by an external electric field.

In the embodiment of the present disclosure, the piezoelectric effect of the first piezoelectric element 20 is utilized to implement the triggering function of the key in the related art.

When the pressing surface 14 is pressed, the pressure is transmitted to the first piezoelectric element 20 through the terminal housing 10, so that the first piezoelectric element 20 is deformed and an electrical signal is output. This process corresponds to the related art pressing a key to generate a trigger signal.

When the pressing of the pressing surface 14 is released, the deformation of the first piezoelectric element 20 is restored, and the output of the electric signal is stopped. This procedure corresponds to the resetting of the key upon activation of the key by contact in the related art.

In one embodiment, the first piezoelectric element 20 is disposed corresponding to the pressing surface 14. Specifically, the first piezoelectric element 20 is connected to the inner wall of the terminal housing 10 at a position corresponding to the pressing surface 14. The first piezoelectric element 20 corresponds to the pressing surface 14, and the first piezoelectric element means: the first piezoelectric element 20 has an overlapping portion with the pressing surface 14 in the direction from the outside to the inside of the terminal housing 10. Accordingly, the pressure applied to the pressing surface 14 is effectively transmitted to the first piezoelectric element 20, and the trigger sensitivity of the first piezoelectric element 20 is improved.

In addition, when the first piezoelectric element 20 corresponds to the pressing surface 14, the area of the pressing surface 14 is preferably smaller than the area of the portion where the first piezoelectric element 20 is connected to the terminal housing 10, so that the pressure applied to the pressing surface 14 is transmitted to the first piezoelectric element 20 as much as possible, and the trigger is achieved in place, thereby optimizing the trigger effect.

In one embodiment, the thickness of the portion of the terminal housing 10 corresponding to the pressing face 14 is smaller than the thickness of the portion of the terminal housing 10 surrounding the corresponding pressing face 14. The trigger sensitivity of the first piezoelectric element 20 is enhanced by thinning a portion of the terminal case 10 corresponding to the pressing surface 14.

Alternatively, the terminal housing 10 has a flat outer side surface, i.e., the pressing surface 14 is flush with a portion around the pressing surface 14; the inner side surface of the terminal housing 10 is formed with a recess corresponding to the pressing surface 14 to achieve thinning. This way the terminal housing 10 has regular outer sides, optimizing the visual effect.

Or, alternatively, the terminal housing 10 has a flat inner side surface, and a depression is formed on the outer side surface of the terminal housing 10, and the depression is the pressing surface 14. This makes the pressing surface 14 distinguished from the region around the pressing surface 14 by the difference in structure.

Alternatively, a recess may be optionally provided on both the inner side and the outer side of the terminal housing 10 to weaken the thickness of the portion of the terminal housing 10 corresponding to the pressing surface 14.

Further, as shown in fig. 5, a visual marker such as an icon or the like is provided at the pressing face 14. Alternatively, tactile markings, such as frosted structures, protrusions, or a predetermined texture, may be provided on the pressing surface 14. The specific position of the pressing surface 14 is facilitated to be clear to the user through visual or tactile identification, and the user experience is optimized.

In one embodiment, the terminal further includes a vibrator disposed inside the terminal housing 10, and the vibrator is attached to the terminal housing 10. The vibrator is used for generating vibration to realize tactile feedback. In particular, in the embodiment of the present disclosure, after the first piezoelectric element 20 outputs the trigger signal, the vibrator generates vibration, so that tactile feedback corresponding to the trigger operation of the first piezoelectric element 20 is realized, and the user experience is optimized.

Wherein, the optional vibrator is a linear motor or a coil motor, etc. Alternatively, the optional vibrator 30 includes a second piezoelectric element 31. In this case, the second piezoelectric element 31 is rapidly deformed by applying a varying electric field to the second piezoelectric element 31 using the piezoelectric effect of the second piezoelectric element 31, and vibration is generated. The second piezoelectric element 31 can form a vibration surface, thereby realizing vibration sensation with uniform intensity distribution and considering the hardware cost of the vibrator.

When the vibrator includes the second piezoelectric element 31, as shown in fig. 6, the first piezoelectric element 20 and the second piezoelectric element 31 are optionally provided with a space 15 therebetween. Deformation mutual noninterference of the two is guaranteed through interval 15, and the independent work guarantees triggering accuracy and feedback effect. The specific size of the space 15 is not limited, and may be selected according to actual installation conditions.

In one embodiment, as shown in fig. 7, the terminal further comprises a controller 40, and the controller 40 is connected to the first piezoelectric element 20 and is configured to receive the electrical signal output by the first piezoelectric element 20. The controller 40 is also connected to the vibrator, and upon receiving the electric signal output from the first piezoelectric element 20, the controller 40 sends an activation command to the vibrator.

Specifically, when the vibrator includes the second piezoelectric element 31 and the power supply element, the power supply element is connected to the controller 40. The power supply element provides an external electric field for the second piezoelectric element 31 according to the start instruction, and excites the piezoelectric effect of the second piezoelectric element 31 to generate vibration.

In one embodiment, the terminal housing 10 comprises a ceramic member and the first piezoelectric element 20 and/or the second piezoelectric element 31 comprise a piezoelectric ceramic element.

Preferably, the first piezoelectric element 20 and/or the second piezoelectric element 31 are formed integrally with the ceramic member of the terminal housing 10. In this case, the integration of the piezoelectric elements (20 and 31) with the terminal housing 10 is improved, and the internal space of the terminal housing 10 is effectively saved.

Wherein the ceramic member of the terminal housing 10 may be selected to be the side 11, or a portion of the side 11; alternatively, the ceramic member is the back cover 12, or a portion of the back cover 12.

In summary, the terminal provided by the embodiment of the present disclosure has the following beneficial effects:

firstly, the first piezoelectric element 21 is deformed by pressing the pressing surface 14 on the terminal housing 10 to output an electrical signal, so as to realize the triggering function of the key. By adopting the terminal, the button function can be realized without arranging an opening on the terminal shell, so that the sealing property and the waterproof property of the terminal are optimized, and the preparation difficulty of the terminal shell is reduced.

Secondly, the piezoelectric effect of the first piezoelectric element 21 is utilized to realize the key function, wherein the first piezoelectric element 21 has a small volume, which is beneficial to saving the space in the terminal device. Particularly, when the first piezoelectric element 21 and the terminal housing are made of ceramic materials, the first piezoelectric element 21 and the terminal housing are integrally formed members. The integration level of the terminal structure is further improved, the internal space of the terminal is increased, and the flexibility of planning the internal space of the terminal is improved.

Thirdly, the key formed by the first piezoelectric element 21 is simple in structure and convenient to produce and manufacture, the first piezoelectric element 21 is relatively fixed in arrangement position and is located inside the terminal, damage is not prone to occurring, and the service life is long.

In a second aspect, embodiments of the present disclosure provide a ceramic structural component that includes a first ceramic structure and a second ceramic structure.

In one embodiment, the second ceramic structure is connected to the first ceramic structure, and the second ceramic structure has a piezoelectric effect property, and is configured to deform when the first ceramic structure deforms, and output an electrical signal.

Wherein the first ceramic structure may be selected as a housing, such as a back cover, or a side of the terminal device. The second ceramic structure may optionally be a piezoelectric ceramic.

The triggering function of the key in the terminal product can be realized through the piezoelectric effect property of the second ceramic structure. And compared with a mechanical key in the related art, the second ceramic structure occupies a small space, and the limitation in planning the internal space of the terminal equipment is reduced. And, need not to set up the mounting hole on the first ceramic structure, improve the leakproofness and the structural stability of whole ceramic structure spare.

In one embodiment, the first ceramic structure and the second ceramic structure are integrally connected by sintering. For example, a first ceramic structure and a second ceramic structure are formed by using a mold, and further sintering is performed to solidify the ceramic green body to form the connected first ceramic structure and second ceramic structure.

In one embodiment, the second ceramic structure has piezoelectric effect properties after being integrally connected with the first ceramic structure through a polarization process.

And the orientation of the dipoles in the second ceramic structure is consistent through polarization treatment, so that the second ceramic structure is endowed with piezoelectric effect properties. Particularly, after the second ceramic structure and the first ceramic structure are connected into a whole by sintering, the second ceramic structure is planned and processed, and the polarization effect is prevented from being influenced by a high-temperature sintering environment.

When the piezoelectric element is used, the pressing surface is pressed for a long time, so that the first piezoelectric element generates continuous deformation and outputs a first electric signal. The pressing surface is pressed for a short time, so that the first piezoelectric element generates instantaneous deformation and outputs a second electric signal. The first electric signal is different from the second electric signal, and in such a case, the long-press operation and the short-press operation of the key are realized by the first piezoelectric element.

And S103, the controller receives the electric signal and adjusts the working parameter of the terminal according to the received electric signal, wherein the working parameter is the parameter indicated by the pressing operation.
