Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.
While a mobile phone will be exemplified in the following description, those skilled in the art will understand that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for mobile purposes.
Please refer to fig. 1 to fig. 2. The embodiment of the invention provides a shell 10, the shell 10 comprises a middle frame 20 and a plurality of pressure sensors 30, wherein at least part of the inner wall of the middle frame 20 is arc-shaped; the plurality of pressure sensors 30 are distributed on the arc-shaped area of the inner wall of the middle frame 20.
In some embodiments, the housing 10 may be applied to electronic devices such as mobile phones, tablet computers, electronic scales, wearable smart devices, and the like. The following will further illustrate the solution of the present application by taking a mobile phone as an example.
In some embodiments, the arcuate region is provided with at least three pressure sensor groups 40, each pressure sensor group including at least one pressure sensor 30. Optionally, the distance between any two adjacent pressure sensor groups is not specially limited; the distance between any two adjacent pressure sensors in the same pressure sensor group is not specially limited.
By arranging at least three pressure sensor groups 40, when the mobile phone is under the action of pressure, whether the mobile phone is pressed effectively or triggered by mistake can be judged according to the pressure distribution of each pressure sensor group 40.
Specifically, a plurality of pressure sensors are included in at least three pressure sensor groups, and the sensors are distributed in all places of the arc-shaped area, for example, a part of the pressure sensors are distributed in the center of the arc-shaped area, and another part of the pressure sensors are distributed in the edge of the arc-shaped area.
The arc-shaped area is assumed to be arranged on the frame of the mobile phone and used as a pressure key area. When the normal pressure operation from the front of the frame exists, the pressure sensors positioned at the two side edges of the arc-shaped area are subjected to smaller pressure, so that the output signal is weaker, and the pressure sensor positioned in the middle of the arc-shaped area is directly pressed by the front, so that the output signal is stronger. After comparing the output signal value of the pressure sensor at the middle and the edge, if the pressure value output by the pressure sensor at the two edges is judged to be obviously smaller than the pressure value output by the pressure sensor at the middle position, the pressure-sensitive key area of the frame can be determined to be pressed positively, and the operation is normal, so that the operation is effective. Compared with the traditional plane structure, the arc-shaped area can enhance the stress of the pressure sensor at the middle position under the condition and reduce the stress at two sides of the edge, so that the characteristics of signals with large middle and small two sides are more obvious, and the lateral extrusion force is more easily identified.
When the pressure operation is performed from the screen or the rear cover, the pressure sensors located at both sides of the edge output a strong signal because they are subjected to a large pressure, and the pressure sensor located in the middle outputs a weak signal because it is not directly pressed against the front. After the output signal values of the pressure sensors at the middle and the edges are compared, if the pressure values output by the pressure sensors at the edges at two sides are judged to be obviously larger than the pressure value output by the pressure sensor at the middle position, the pressure-sensitive key area of the frame can be determined not to be pressed by the front side, and therefore the key event is not recorded as an effective key event for misoperation. Compared with the traditional plane structure, the stress of the pressure sensors on the two sides of the edge can be enhanced by the arrangement of the arc-shaped area, the stress of the middle position is reduced, the signal characteristics of small middle and large two sides are more obvious, and therefore the lateral extrusion force is easier to identify.
When pressure is caused by the distortion of the middle frame 20, the force exerted on the pressure sensors at the two sides of the edge is centrosymmetric, that is, along the length direction of the frame, the force exerted on the pressure sensors at one side edge is gradually decreased, and the force exerted on the pressure sensors at the other side edge is gradually increased. Therefore, the electric signals output by the pressure sensors on the two sides of the edge are compared, and if the characteristics are met, the current stress caused by distortion of the middle frame can be judged, so that the misoperation is realized, and the effective key event is not recorded.
Through the arrangement, when different types of forces are applied, the output signals of the pressure sensors distributed in the arc-shaped area show different characteristics, so that the stress type can be identified according to the characteristics of the output signals of the pressure sensors, and the current stress is determined to be caused by effective operation of a user or caused by misoperation, so that the misoperation can be effectively identified.
In some embodiments, at least three pressure sensor groups 40 are distributed circumferentially along the arcuate region.
In some embodiments, the at least three pressure sensor groups 40 include a first pressure sensor group 41 disposed in a central region of the arc region and a second pressure sensor group 42 and a third pressure sensor group 43 disposed on both sides of the first pressure sensor group 41, respectively. Alternatively, the distance between the second pressure sensor group 42 and the first pressure sensor group 41 and the distance between the third pressure sensor group 43 and the first pressure sensor group 41 may be the same or different. For example, the distance between the second pressure sensor group 42 and the first pressure sensor group 41 is smaller than the distance between the third pressure sensor group 43 and the first pressure sensor group 41 of the first pressure sensor group 41, or the distance between the second pressure sensor group 42 and the first pressure sensor group 41 is larger than the distance between the third pressure sensor group 43 and the first pressure sensor group 41.
By arranging at least three pressure sensor groups 40, when the mobile phone is under the action of pressure, whether the mobile phone is pressed effectively or triggered by mistake can be judged according to the pressure distribution of each pressure sensor group 40.
In some embodiments, the second pressure sensor group 42 and the third pressure sensor group 43 are symmetrically disposed on both sides of the first pressure sensor group 41. Through the symmetrical arrangement, the output electrical signals of the second sensor group 42 and the third sensor group 43 will present a symmetrical characteristic relative to the output signal of the first sensor group during normal pressing, and when normal pressure operation from the front of the frame occurs, normal pressing and abnormal pressing can be identified more quickly and better.
In some embodiments, as shown in fig. 3. At least part of the section of the inner wall of the middle frame 20 along the length direction of the middle frame 20 is an arc shape protruding towards the inner wall of the middle frame 20; at least three pressure sensor groups 40 are distributed along the width direction of the middle frame 20, and each pressure sensor group 40 includes a plurality of pressure sensors 30 arranged along the length direction of the middle frame 20. Alternatively, each pressure sensor group 40 may include the same or different number of pressure sensors 30; the distance between two adjacent pressure sensors 30 of each pressure sensor group 40 is arbitrary and can be arbitrarily selected according to the requirement.
By arranging at least three pressure sensor groups 40 in the width direction of the middle frame 20, when the mobile phone is under pressure, whether the mobile phone is pressed effectively or triggered by mistake can be judged according to the pressure distribution of each pressure sensor group 40.
In some embodiments, the middle frame 20 is a polygonal middle frame 20 formed by connecting a plurality of frames, wherein the inner wall of at least one frame is arc-shaped; or at least one section of the inner wall of at least one frame is arc-shaped. Taking a rectangular mobile phone as an example to continue the description, the middle frame 20 of the mobile phone is a quadrilateral middle frame 20 formed by connecting 4 side frames, and the arc-shaped area can be arranged on the side frame or a certain section of the side frame.
By arranging the inner wall of the bezel in an arc shape or arranging a section of the inner wall of the bezel in an arc shape, an arc-shaped area for mounting the pressure sensor 30 or the pressure sensor group 40 can be formed.
The invention also provides a terminal comprising a housing as described in any of the above. That is, the terminal uses the above-described housing. The shell 10 comprises a middle frame 20 and a pressure sensor 30, wherein at least partial area of the inner wall of the middle frame 20 is arc-shaped; the pressure sensor 30 is disposed in an arc-shaped region of the inner wall of the middle frame 20.
The pressure sensors 30 arranged in the arc area are distributed, the positions of the pressure sensors 30 in the middle position are more protruded than the positions of the pressure sensors 30 on two sides, when different types of forces are applied, the output signals of the pressure sensors distributed in the arc area can present different characteristics, so that the stress type can be identified according to the characteristics of the output signals of the pressure sensors, and then the current stress is determined to be caused by effective operation of a user or be caused by misoperation, so that misoperation can be effectively identified.
The terminal may be implemented in various forms. For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a smart band, a pedometer, and the like, and a fixed terminal such as a Digital TV, a desktop computer, and the like.
Please refer to fig. 4. The invention also provides a pressure detection method, which is applied to any one of the shell or the terminal, and the pressure detection method comprises the following steps:
s101, pressure information output by a pressure sensor arranged in an arc-shaped area of the inner wall of the middle frame is obtained.
Specifically, as shown in fig. 1-3, the arc-shaped area of the inner wall of the middle frame is provided with a plurality of pressure sensors 30, the plurality of pressure sensors 30 can be divided into at least one pressure sensor group 40, and each pressure sensor group 40 comprises at least one pressure sensor 30. For example, 3 pressure sensor groups 40 are disposed over the arc area, each pressure sensor group 40 including at least one pressure sensor 30.
Optionally, the pressure information may include a pressure value. By acquiring the pressure information output by the pressure sensors, the pressure distribution of the arc-shaped area of the inner wall of the middle frame can be determined, and the stress type of the arc-shaped area can be further determined. For example, when the central position of the arc-shaped area is subjected to a large force and the edge position is subjected to a small force, the force type may be determined as the force applied at the central position of the arc-shaped area, and when the central position of the arc-shaped area is the preset key position, the force type may be determined as the forward pressing force generated by the key operation of the user. On the contrary, when the central position of the arc-shaped area is under small stress and the edge position is under large stress, the stress type can be determined to be the acting force at the side position of the arc-shaped area, and when the central position of the arc-shaped area is the preset key position, the stress type can be determined to be the lateral pressing force generated by the misoperation of the user.
And S102, determining whether the pressing operation corresponding to the pressure information is a preset effective pressing operation or not according to the pressure information.
When the central position of the arc-shaped area is stressed largely and the edge position is stressed less, the pressure can be determined to be effective pressing, and at this time, the pressure value of the pressure sensor 30 of the first sensor group 41 is the largest, so that normal pressing operation can be determined, and a normal key event is reported.
When the stress of the central position and the stress of the edge position of the arc-shaped area are small and large, the pressure can be determined as the misoperation, and the pressure values of the second sensor group 42 and the third sensor group 43 are larger than the pressure value of the first sensor group 41, so that the abnormal pressing operation can be judged, and the key event is not reported.
When the pressure is caused by the distortion of the middle frame 20, the force applied to the pressure sensors on both sides of the edge will exhibit a central symmetry characteristic. Therefore, when the force exerted on the plurality of pressure sensors at the edge of one side is gradually reduced and the force exerted on the plurality of pressure sensors at the edge of the other side is gradually reduced along the specific direction of the length of the middle frame, that is, when the output signal laws of the pressure sensors at the edges of the two sides are opposite, the stress type can be judged to be the twisting force.
According to the embodiment, at least partial area of the inner wall of the middle frame is set to be the arc area, a plurality of groups of pressure sensor groups are arranged in the arc area, when different types of forces are applied, output signals of a plurality of pressure sensors distributed in the arc area have different characteristics, so that the stress type can be identified according to the characteristics of the output signals of the pressure sensors, and then the current stress is determined to be caused by effective operation of a user or be caused by misoperation, so that misoperation can be effectively identified.
Please refer to fig. 5. In some embodiments, determining whether the pressing operation corresponding to the pressure information is a preset effective pressing operation according to the pressure information specifically includes the following steps:
s103, determining the stress type of the shell according to the pressure information output by each pressure sensor group, wherein the stress type comprises at least one of positive pressing force, lateral extrusion force and twisting force.
In this embodiment, the forward pressing force refers to an acting force when the center position of the arc-shaped area is pressed forward, and therefore, when the pressure value of the first pressure sensor group located in the center area is greater than the pressure values of the second pressure sensor group and the third pressure sensor group 43 located in the edge area, it can be determined that the force type is the forward pressing force.
The lateral extrusion force is the action force when the edge position of the arc-shaped area is extruded; the twisting force is the acting force when the middle frame or the shell where the arc-shaped area is located is twisted. The two types of the pressure sensors are non-positive pressing, so that in the first case, when the pressure values of the second pressure sensor group and the third pressure sensor group which are positioned at two sides are simultaneously greater than the pressure value of the first pressure sensor group, the stress type can be judged to be lateral pressing force; in the second case, when there is a pressure due to the distortion of the middle frame 20, the force applied to the pressure sensors located at both sides of the edge will exhibit a central symmetry characteristic, and therefore, when the output signals of the plurality of pressure sensors in the second pressure sensor group are sequentially increased and the output signals of the plurality of pressure sensors in the third pressure sensor group are sequentially decreased along a specific direction of the length of the middle frame, it can be judged that the force type is a distortion force. Alternatively, when the output signals of the plurality of pressure sensors in the second pressure sensor group are sequentially decreased and the output signals of the plurality of pressure sensors in the third pressure sensor group are sequentially increased in a specific direction along the length of the middle frame, it may be determined that the force type is a twisting force.
And S104, determining whether the pressing operation corresponding to the pressure information is effective pressing operation or not according to the stress type.
By analyzing the force type of the housing, it can be determined whether the user has applied a valid pressing operation to the housing. For example, when the above-mentioned plurality of pressure sensors are used as the pressure detecting elements of the pressure-sensitive keys, and the central position of the arc-shaped area is the key position, the forward pressing force is generally generated by the normal key operation of the user, and the lateral pressing force and the twisting force are generally generated by other actions than the normal key operation. It is thus possible to specify: if the force type is positive pressing force, the pressing operation is effective, and otherwise, the pressing operation is not effective. And after the operation is judged to be effective, according to the result, the action of reporting the key event or not reporting the key event is executed, so that the effect of preventing misoperation is achieved.
Please refer to fig. 6. In some embodiments, the pressure information includes a first pressure value detected by the first pressure sensor group 41, a second pressure value detected by the second pressure sensor group 42, and a third pressure value detected by the third pressure sensor group 43. Correspondingly, determining the stress type of the shell specifically includes the following steps:
and S105, if at least one of the second pressure value and the third pressure value is greater than the first preset value and the first pressure value is smaller than the first preset value, determining that the stress type of the shell is lateral extrusion force.
Alternatively, the first pressure value may comprise the pressure values of the individual sensors in the first sensor group 40, or be the mean or median of the pressure values of the plurality of pressure sensors 30 in the first sensor group 40.
The second pressure value may comprise a pressure value of each sensor of the second sensor group 40, or a mean or median of pressure values of the plurality of pressure sensors 30 of the second sensor group 40.
The third pressure value may comprise the pressure values of the individual sensors in the third sensor group 40, or may be a mean or median of the pressure values of the plurality of pressure sensors 30 in the third sensor group 40.
When the two sides of the middle frame are extruded, the stress of the pressure sensors at the two sides is large, and the stress of the pressure sensor at the middle position is small, so that when the pressure values of the pressure sensors accord with a rule from large to small or from small to large, the stress type of the shell is determined to be lateral extrusion force, the pressing force is directly judged to come from the direction of the screen and the rear cover, and the system does not report a key event for misoperation.
S106, if the first pressure value is larger than the second preset value, and the second pressure value and the third pressure value are both smaller than the second preset value, determining that the stress type of the shell is the forward pressing force.
When the middle position of the middle frame is pressed, the stress of the pressure sensors at the two sides is small, and the stress of the pressure sensor at the middle position is large.
And S107, if the plurality of second pressure values output by the pressure sensors 30 continuously arranged in the second pressure sensor group 42 conform to a rule from large to small or from small to large, and the plurality of third pressure values output by the pressure sensors 30 continuously arranged in the third pressure sensor group 43 conform to a rule opposite to the second pressure values, determining that the stress type of the shell is a twisting force.
When there is a pressure caused by the distortion of the middle frame 20, the force exerted on the pressure sensors located on both sides of the edge will exhibit a central symmetry characteristic, and therefore, when the output signals of the plurality of pressure sensors arranged in series in the second pressure sensor group sequentially increase and the output signals of the plurality of pressure sensors in the third pressure sensor group sequentially decrease along the specific direction of the length of the middle frame, it can be determined that the type of the force exerted is a distortion force. Alternatively, when the output signals of the plurality of pressure sensors arranged in series in the second pressure sensor group decrease in sequence and the output signals of the plurality of pressure sensors in the third pressure sensor group increase in sequence along a specific direction of the length of the middle frame, it may be determined that the force type is a twisting force.
According to the method of the steps, the stress type can be uniquely determined, and whether effective pressing operation is applied to the shell by a user can be further determined.
In some embodiments, determining whether the pressing operation corresponding to the pressure information is an effective pressing operation according to the force type specifically includes the following steps:
and S104A, if the force type is positive pressing force, determining that the pressing operation corresponding to the pressure information is effective pressing operation.
And S104B, if the force type is the lateral extrusion force and the twisting force, determining that the pressing operation corresponding to the pressure information is not the effective pressing operation.
In some embodiments, after determining that the pressing operation corresponding to the pressure information is not a valid pressing operation if the force type is a lateral pressing force and a twisting force, the method further includes the following steps:
when it is determined that the pressing operation is not a valid pressing operation, a response to the pressing operation is denied.
When the pressing operation does not belong to the effective pressing operation, the pressing operation is refused to be responded, and when the pressing operation is the effective pressing operation, the pressing operation is responded, so that misoperation is avoided, and the safety of the mobile phone is improved.
In one embodiment, when it is determined that the pressing operation is an effective pressing operation, the triggering position of the signal can be further determined according to the ratio of the signal intensity of each pressure sensor in the first pressure sensor group located at the middle position of the arc-shaped area, so as to obtain the exact key pressing position actually pressed by the user.
In a specific embodiment, the housing and the pressure detection method are applied to a mobile phone, at least a partial area of a frame of the mobile phone is provided with an arc-shaped area, and three pressure sensor groups are arranged on the arc-shaped area. Specifically, the arc-shaped area extends along the length direction of the middle frame, that is, the arc-shaped area is an arc-shaped cylindrical area, the three pressure sensor groups are specifically three rows of pressure sensors distributed on the arc-shaped cylindrical area, and each row of pressure sensors is a group. The currently detected pressing operation is judged to be effective pressing operation or false triggering operation aiming at the key according to the pressure distribution of the two rows of sensors at the arc-shaped edge, so that the aims of detecting effective pressing and avoiding false triggering are fulfilled.
Specifically, when a normal key operation is performed from the front side of the frame, the mobile phone recognizes that the pressure values sensed by the two sensor groups at the edge of the arc-shaped area are small, and the pressure value of the sensor group in the middle is large; if the pressure distribution of the three groups of pressure sensors accords with the characteristics, the fact that the user effectively presses the frame is judged, and the key processing program can normally report the key event.
When there is a squeezing force from the screen or the rear cover, the two sensor groups on both sides of the arc area will sense a greater pressure value, while the pressure value of the middle pressure sensor group is the smallest. At this time, the pressure signal is considered to be caused by the misoperation of the user, and the key event is not reported by the key processing program.
When pressure is caused by distortion of the middle frame 20, one of the pressure sensor groups 40 on two sides of the arc-shaped area generates a pressure distribution from light to heavy, and the other generates a pressure regular distribution from heavy to light. At this time, it can be judged that the pressure signal is caused by the misoperation of the user, and the key event is not reported by the key processing program.
