1 and FIG. 2 are schematic diagrams of the smart terminal 110 and the housing 120 of the terminal assembly 100 in accordance with an embodiment of the present invention when they are not installed and when they are installed. The housing 120 is sleeved on the smart terminal 110. In addition, it is used as a protective shell for the smart terminal 110, or as one of the modules of the smart terminal 110, forming a part of a shell that can be inserted and detached. When the housing 120 is set outside the smart terminal 110, the user’s grip on the smart terminal 110 will also be transferred to the grip on the housing 120, and the user’s pressing on the housing 120 will also be transferred to the smart terminal 110. Press. When it is necessary to feed back the user's confirmation of receipt of an external command, the housing 120 will also give the user a feel of pressing the physical buttons. In view of this, the shell of the smart terminal 110 in this embodiment can be continuously formed, that is, it is non-porous or non-porous. With a seam design, there is no longer any physical button on it, and all the original physical button command reception, movement, feedback, etc. will be completed by the housing 120. Therefore, a pressing unit 121 is provided on the housing 120, and a sensor module 111 corresponding to the pressing unit 121 is provided in the smart terminal 110. The pressing unit 121 is externally provided and can be used to receive the pressing force applied to the pressing unit 121 when the user wants to perform an operation. Specifically, the pressing unit 121 includes a pressing portion and a triggering portion. The pressing portion is arranged facing the outer direction of the housing 120, that is, facing the outside, and receives the pressing force applied by the user. As the pressing portion leaves the initial position, it will be expected to return to the initial position. The reaction force is the feedback force, and the feedback force is applied to the user. The triggering part is elastically connected with the pressing part, moves together with the pressing part, and also due to displacement, can assist in generating the feedback force. In other words, when the pressing force acts toward the inside of the housing 120, the pressing part and the triggering part of the pressing unit 121 will extend into the inside of the housing 120, that is, move toward the corresponding sensor module 111. With the extension of the pressing unit 121, when the extended distance is basically equal to the stroke of the pressing unit 121, such as the maximum stroke, the triggering part will trigger the sensor module 111. The triggering method can be as part of the triggering part and the sensor module 111 In direct contact, the trigger part changes the external detection data of the sensor module 111. It can also change the external detection data of the wireless signal, such as the wireless signal sent by the trigger part and the sensor module 111 or the induction of a wireless sensor device. Contact type trigger sensor module 111. When the sensor module 111 is triggered by the pressing unit 121, the sensing result is that it receives an operation instruction applied by the user through the pressing unit 121, and executes the corresponding operation according to the operation instruction, so as to finally realize from the user pressing the pressing unit 121 to the execution Steps of operation. After that, when the user finds that the pressing force applied by himself has brought the execution of the desired instruction, he will reduce the pressing force or directly release the pressing force, the pressing part and the trigger part move in the direction of releasing the pressing force, and the above feedback is generated to the user when moving Until it returns to the initial position. It is understandable that since the pressing unit 121 is disposed on the housing 120, and the smart terminal 110 is only provided with the sensor module 111 for mutual inductive cooperation with the pressing unit 121, there is no need to open a hole on the smart terminal 110 to place a pressure receiving device. The physical keys and the loss of the physical keys after being pressed will be borne by the pressing unit 121 on the housing 120. When the pressing unit 121 is damaged, replacing the pressing unit 121 or the housing 120 can provide a new physical key feel to the user. In addition, according to the different configurations of the sensor module 111, the configuration of the pressing unit 121 may be different, but it is also understandable that the part of the pressing unit 121 facing the user side, namely the pressing part, is a metal button that can feedback the pressing feel. , Plastic buttons, rubber buttons, etc., and the part far away from the pressing unit 121 on the user side, that is, the trigger part, can adjust the structure according to different sensor module 111 configurations, so as to satisfy any type of smart terminal 110.

The mutual sensing process of the pressing unit 121 and the sensor module 111 is described in detail below according to the configuration of the sensor module 111 in different embodiments.

Example one

Referring to FIG. 2, in this embodiment, the sensor module 111 includes a magnetic sensor. The magnetic sensor converts changes in the magnetic properties of sensitive elements caused by external factors such as magnetic field, current, stress and strain, temperature, light, etc., into electrical signals, and detects them in this way. The corresponding physical quantity device. The pressing unit has a built-in magnetic element, and all or part of the stroke of the pressing unit during reciprocating motion is within the sensing range of the magnetic sensor. The reciprocating movement of the pressing unit causes the pressing unit to non-contact trigger the magnetic sensor within the sensing range.

specifically. The magnetic sensor can be a Hall sensor, which is a magnetic field sensor made according to the Hall effect. A Hall semiconductor chip is required in the magnetic field generated by the magnetic field sensor, and a constant current I passes through the chip. Under the action of the Lorentz force, the electron flow of I shifts to one side when passing through the Hall semiconductor, causing the plate to generate a potential difference in the vertical direction, that is, the Hall voltage. The Hall voltage changes with the intensity of the magnetic field. The stronger the magnetic field, the higher the voltage, the weaker the magnetic field, and the lower the voltage. The Hall voltage value is very small, usually only a few millivolts, but by the amplifier in the integrated circuit, the voltage can be amplified enough to output a strong signal. If the Hall IC is used for sensing, when the magnetic induction line generated by the magnetic field is cut mechanically, the change of the magnetic flux in the magnetic field will be changed. Therefore, corresponding to the magnetic sensor, the pressing unit 121 has a built-in magnetic element, and the placement position of the magnetic element is: when the pressing unit 121 reciprocates according to the received pressing force, the magnetic element will pass through the magnetic induction line generated by the magnetic sensor, for example The magnetic element is originally located in the magnetic field. The stroke change of the pressing unit 121 will drive the position of the magnetic element in the magnetic field to cut the magnetic induction lines at different positions in the magnetic field, or the magnetic element is originally located outside the magnetic field and changes with the stroke of the pressing unit 121 Enter the magnetic field and cut the magnetic induction lines in the magnetic field; or the magnetic element is originally located in the magnetic field and fixed at a certain position in the magnetic field. The stroke change of the pressing unit 121 will drive the magnetic element out of the magnetic field. The cutting of the magnetic induction line during the moving process of the magnetic sensor changes the induction information of the magnetic sensor. Through the Hall effect-based induction of the magnetic element and the magnetic induction line, the pressing unit 121 can trigger the magnetic sensor in a non-contact manner.

It is understandable that the magnetic sensor may be arranged inside the smart terminal 110, and it is not easy to observe the presence of the sensor module 111 on the surface of the smart terminal 110. The pressing unit 121 may be arranged above the magnetic sensor and arranged in a substantially horizontal setting (in a state where the smart terminal 110 is placed horizontally). When the pressing unit 121 receives a pressing force, it will retract toward the center of the smart terminal 110. The initial position of the triggering portion 123 can be completely hidden in the housing, or partially extended to the projection range of the smart terminal. The magnetic element is arranged at the end of the pressing unit 121, that is, the triggering portion 123, which is also retracted along with the pressing unit 121. In, cut the magnetic induction line perpendicular to the surface of the smart terminal 110.

In other embodiments, the magnetic sensor may be an anisotropic magnetoresistance sensor, giant magnetoresistance sensor or tunnel magnetoresistance sensor. Anisotropic Magneto-Resistance Sensor (AMR (Anisotropic Magneto Resistance) Sensor), a single magnetic layer device, is based on parallel magnetic field induction at 1 to 3% △R/R (maximum resistance change rate) and 45° deflection angle, passing current It flows in the film plane and has a narrow working field. The resistance of a giant magnetoresistance sensor (GMR (Giant Magneto Resistance) Sensor) depends on the scattering of spin electrons at the film interface, and most electrons cannot form scattering. At room temperature, the GMR's △R/R (maximum resistance) Change rate) <20%. The tunneling magnetoresistance sensor (TMR (Tunneling Magneto Resistance) Sensor) uses the spin characteristics of electrons. When the electrons pass through the second layer of magnetic material, the direction of the spin of the electrons is defined, and the electrons with spin pass through the quantum tunneling effect. Pass the MgO (magnesium oxide) insulating layer, and then selectively pass through the magnetic layer (the same spin will pass-low resistance, otherwise it will not pass-high resistance). At room temperature, the △R/R of TMR (maximum Resistance change rate) can reach more than 500%.

In a further embodiment, the pressing portion 122 of the pressing unit 121 is disposed on the side surface of the housing 120 and located above or below the magnetic sensor. The pressing unit 121 includes a pressing key as the pressing part 122 and a folding rib as the triggering part 123. The pressing key is exposed outside the housing 120 and is used to receive the pressing force applied by the user. The fixed end of the folding rib is pivotally fixed at When the free ends of the side edges of the housing 120 extend outward, the entire folding ribs are arranged perpendicular to the surface of the smart terminal 110. An elastic element is connected between the folding rib and the pressing key. After the pressing key is driven by the pressing force, the elastic element drives the folding rib to rotate along the pivot axis, so that it is perpendicular to the surface of the smart terminal 110 and parallel to the smart terminal 110. The surface of the terminal 110 is switched between the same direction (parallel) with the magnetic induction line and the state perpendicular to the magnetic induction line. The switching between the two states will also cut the magnetic induction line to trigger the magnetic sensor. Through the configuration in this embodiment, a simple structure and the size of small parts can be used to save the required space on the housing 120, instead of the induction of the magnetic sensor by the folding of an entire protective cover in the prior art. Even if the terminal assembly 100 is covered with the casing 120 on the smart terminal 110, the external contour of the terminal assembly 100 is consistent and integral, which conforms to the user's usage and aesthetic habits.

Example two

In this embodiment, the sensor module 111 includes a capacitive sensor, which is a sensor that converts other quantities into a change in capacitance. It is mainly composed of upper and lower electrodes, an insulator, a substrate, and a thin film. Under the action of pressure, the thin film produces a certain deformation, and the distance between the upper and lower electrodes changes, resulting in a change in capacitance. The capacitive sensor can be set at any position of the smart terminal 110, such as the back shell, side of the smart terminal 110, or the end face with a display unit, according to the user survey of the smart terminal 110 manufacturer, to detect whether the user has a press trigger, fingerprint detection, etc. . In this embodiment, through the arrangement of the pressing unit 121, the user does not directly contact the sensing surface of the capacitive sensor, but instead uses the pressing unit 121 as an intermediate piece to transmit the pressing operation. specifically. When the pressing part of the pressing unit 121 receives the pressing force, the triggering part is brought into contact with the surface of the capacitive sensor, thereby changing the sensing capacitance of the capacitive sensor, and then triggering the capacitive sensor. Through indirect touch triggering, the user’s touch trigger on the capacitive sensor changes to an operation on the pressing unit 121, and the stroke feedback of the pressing unit 121 can give the user a feedback feel that the original capacitive sensor does not produce, thus giving the user even For fixing different capacitive sensors, it can also have the effect of pressing physical buttons.

The pressing unit 121 may also have different structures for receiving pressing force. For example, the trigger part of the pressing unit 121 may be a key element, that is, a standard physical key structure. The stroke of the key element is the same as the direction of the pressing force. When the key element is pressed, the key element is in contact with the surface of the capacitive sensor to change the sensing capacitance; the trigger part of the pressing unit 121 can also be a roller element, and the pressing part protrudes from the housing In addition to 120, the pressing force can be the force perpendicular to it, or the thrust that rotates the roller element around the roller. With the application of the thrust, different parts of the roller element will contact different surface positions of the capacitive sensor and change The sensing capacitance of the capacitive sensor is used to simulate the sliding touch operation that the original user applied to the capacitive sensor to slide on its surface. Not only can it give the user press feedback, but it can also provide the user with a scrolling experience, which further improves the user's hand experience in the original physical button operation.

Example three

In this embodiment, the sensor module 111 includes a piezoelectric sensor, such as a thin-film operating part installed on the smart terminal 110, which is a sensor made by using piezoelectric effect generated by certain dielectrics. Piezoelectric effect refers to the phenomenon that certain dielectrics undergo deformation (including bending and stretching deformation) due to the polarization of internal charges when they are deformed by an external force in a certain direction. The sensing surface of the piezoelectric sensor is arranged on the surface of the smart terminal 110, the pressing portion of the pressing unit 121 includes a key element (which may be the same as or different from the key element in the second embodiment), and the position of the key element is opposite to the position of the sensing surface. Suppose, when the button element receives the pressing force, the user's finger squeezes the button element, and the button element then squeezes the sensing surface of the piezoelectric sensor, changing the induced voltage of the piezoelectric sensor to trigger it. Through the setting of the button element, the original user's direct extrusion of the piezoelectric sensor will use the button element as the middle part to transfer the pressing force, and the feedback of the button element to the user's finger can be the button feedback obtained after the user applies the pressing force , Thus increasing the refreshing feel of the physical buttons on the original basis.

Regarding the sensor types included in the different sensor modules 111 in the above three embodiments, when the user needs to apply an operation instruction, the objects of its operation will be grouped into the operation of the pressing unit 121. By unifying the operation objects, any type of intelligent The terminal 110 is used as an adaptive application. After any smart terminal 110 is covered with a housing 120 to form the terminal assembly 100, the pressing unit 121 corresponds to the position of the sensor module 111, and the elastic feedback of the pressing unit 121 can be used to provide the user with The physical button feel. In addition, the direct triggering of the sensor module 111 by the pressing unit 121 eliminates the need for additional installation of application mapping buttons on the smart terminal 110, improves the triggering speed, and reduces user feedback delay.

In any embodiment, the housing 120 and the smart terminal 110 are connected to each other by one of snapping, snapping, magnetic attraction, and locking nails, so that the housing 120 and the smart terminal 110 are firmly connected. For example, when connected by a snap connection, the housing 120 has a cavity, and the smart terminal 110 is accommodated in the cavity and is in interference fit with the inner wall of the housing 120; for another example, when connected by a snap connection, the housing 120 There are fasteners inside to lock the shell of the smart terminal 110; for example, when the smart terminal 110 is connected in a magnetic manner, the smart terminal 110 and the housing 120 are respectively provided with magnetic components, and the magnetic components are connected to each other to stabilize the housing 120 and The relative position of the smart terminal 110.

In order to realize the feel of the user's physical buttons after being pressed on the pressing unit 121, the pressing unit 121 can be plastic soft rubber molding, plastic elastic wall molding, spring molding, soft rubber molding, hot melt molding, viscose molding, or screw molding. One of them. The physical buttons commonly found on the smart terminal 110, household appliances, and mechanical equipment can be transferred to the embodiments of the present invention.

Smart terminals can be implemented in various forms. For example, the terminals described in the present invention may include smart terminals such as mobile phones, smart phones, notebook computers, PDAs (personal digital assistants), PAD (tablet computers), PMP (portable multimedia players), navigation devices, etc., and smart terminals such as Fixed terminals for digital TV, desktop computers, etc. Below, assume that the terminal is a smart terminal. However, those skilled in the art will understand that, in addition to elements particularly used for mobile purposes, the configuration according to the embodiments of the present invention can also be applied to fixed-type terminals.
