Description

Pressure detection data processing method, device and system and handheld device thereof

Technical Field

The invention belongs to the technical field of electronic equipment, and particularly relates to a pressure detection data processing method, device and system and handheld equipment thereof.

Background

The existing intelligent handheld equipment is mostly handheld equipment with HOME keys, some handheld equipment is also provided with a pressure sensor unit at the side edge, only one piece of pressure detection data is output according to data detected by one or more pressure sensor units so as to represent the pressure applied to the handheld equipment by a user, under one condition, the pressure detection data is compared with a preset pressure grade according to the pressure detection data, and once the pressure detection data falls into a certain preset grade, an application is correspondingly started or a certain operation is triggered. Although the operation mode of the handheld device is enriched by utilizing the pressure detection mode, and some common application programs are convenient to start, the pressure grade division is limited, and the space for developing the application related to the handheld device is not large, so that the problem that a large number of manufacturers in the prior art research the pressure detection technology but do not generate scale commercial use due to the limitation of market application is caused. In addition, there is also a technology that detects the pressure applied to the handheld device and the time (which may be called a pressing time) of the user applying the pressure to the handheld device at the same time, compares the output pressure detection data and the pressing time with the preset pressure detection data and the preset time, respectively, identifies the time parameters (long pressing and short pressing) at the same time of identifying the pressure, and operates the relevant application of the handheld device through the detection of two dimensions of the pressure and the time. Although the application range is expanded to a certain extent, because the operation is distinguished by time, the user needs to wait for the pressing time and remember the corresponding pressure and time parameters at the same time, thereby bringing inconvenience to the user. For example, there are many applications related to the handheld device, such as waking up, unlocking a camera, messaging, answering a call, etc., and if it is assumed that a preset long press exceeds a certain pressure detection data, the camera is started, and if it is assumed that a short press exceeds a certain pressure detection data, the answering call is started, and thus, a user may have a malfunction due to inaccurate understanding of the duration.

In summary, the usability of the handheld device based on pressure detection in the prior art is not good.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, some embodiments of the present application will be described in detail by way of example with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the examples, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

Referring to fig. 1, fig. 1 is a front view of a handheld device with a pressure detection data processing method according to the present application, and the handheld device 100 may include a camera module 110, an infrared camera module 120, a first pressure sensor module 130, a second pressure sensor module 140, and a screen 150. The camera module 110 and the infrared camera module 120 can perform face recognition together, and the screen 150 can be a full screen. When the user holds the handheld device with his hand, typically, the thumb 210 presses the right side frame of the handheld device, the pressure is applied to the second pressure sensor module 140, the other fingers 220 press the left side frame of the handheld device, and the pressure is applied to the first pressure sensor module 130. For example, the first pressure sensor module 130 and the second pressure sensor module 140 are respectively used for detecting the pressure generated by pressing the fingers (or hands) on two sides. The first pressure sensor module 130 and the second pressure sensor module 140 may respectively include a plurality of pressure sensor units, the plurality of pressure sensor units are distributed at different positions of the handheld device, the plurality of pressure sensor units are used to perform pressure detection on a plurality of touch areas (or touch points), and the plurality of detected pressure detection data are sequentially arranged according to a time sequence to form a multi-dimensional pressure matrix, so as to precisely identify the gesture and/or force application distribution of the user holding the device. In an embodiment, the first pressure sensor module 130 may output S pressure signals, the second pressure sensor module 140 may output N pressure signals, and the S + N pressure signals may form a multi-dimensional pressure matrix according to the requirement of the application end and the distribution of the pressure sensor units.

Please refer to fig. 2 and fig. 3 together. Based on the disclosure of the above embodiments, optionally, in this embodiment, the first pressure sensor module 130 includes 3 pressure sensor units, which are the first pressure sensor unit 131, the second pressure sensor unit 132, and the third pressure sensor unit 133, respectively. Fig. 3 is a right side view of a handheld device, and as shown in fig. 3, the second pressure sensor module 140 includes 3 pressure sensor units, namely, a fourth pressure sensor unit 141, a fifth pressure sensor unit 142, and a sixth pressure sensor unit 143. The above 6 pressure sensor units are all located in different touch areas. The first pressure sensor module 130 can output 3 pressure signals, the second pressure sensor module 140 can output 3 pressure signals, and output 6 pressure signals in total, the pressure signal processing circuit processes the 6 pressure signals into 6 pressure detection data, and according to the time sequence, the handheld device processor module sequentially arranges the obtained 6 pressure detection data into a 3 × 2 matrix or a 2 × 3 matrix, but not outputs single pressure detection data after averaging or other operations.

The number of the pressure sensor units can be designed according to requirements, and the embodiment of the application does not limit the number.

The number and the layout of the pressure sensor units are not limited to those shown in the figures, and different combination layouts can be performed in combination with the structure of the handheld device, for example, 4 pressure sensor units are arranged on the left side, 2 pressure sensor units are arranged on the right side, or vice versa, and the embodiment of the present application does not limit the number and the layout.

It should be understood that in the present embodiment, each pressure sensor module may include a plurality of pressure sensor units, a flexible circuit board, and an interface. Of course, the pressure sensor module may also include only one pressure sensing unit, for example, a pressure sensor module including only one pressure sensing unit may be disposed on the upper right side of the handheld device.

It should be noted that fig. 1-3 show the pressure sensor modules on the handheld device for ease of description, but in practical cases, the pressure sensor modules are not visible from the outside if the outer frame material or the housing material of the handheld device is non-transparent. Of course, in the case of using a non-transparent material, the housing may be frosted at a position corresponding to the pressure sensor unit to provide a tactile sensation different from that of the surrounding material, thereby improving the user experience.

Fig. 4 is a partial cross-sectional view of the hand-held device of fig. 1. Based on the disclosure of the above embodiment, optionally, in this embodiment, the second pressure sensor module 140 is disposed on the inner wall of the right side frame 160 of the handheld device, and the manner of the second pressure sensor module is a fitting type, specifically: the pressure sensor unit 141 is attached to the inner wall of the right bezel 160 of the handheld device by the attaching glue 1412. The pressure sensor unit is connected to a flexible circuit board 1413, and the flexible circuit board 1413 is connected to the interface. For example, when a user holds the handheld device with his hand, and applies an external force to the outer wall of the right side frame 160 of the handheld device, the right side frame 160 deforms, and transmits a deformation signal to the pressure sensor unit through the right side frame 160 of the handheld device and the adhesive 1412, and the pressure sensor unit outputs a pressure signal representing the magnitude of the force applied according to the applied force. The pressure signal is transmitted to the pressure signal processing circuit through the flexible circuit board 1413 and the interface.

As another embodiment, as shown in fig. 5, the second pressure sensor module is disposed on the inner wall of the right side frame 260 of the handheld device, and the method is embedded, specifically: the pressure sensor unit is arranged in the frame material of the right side frame 260 of the handheld device by a high-temperature injection molding method. The pressure sensor unit 231 is connected to the contact 262, and is connected to the pressure signal processing circuit through the contact 262. For example, when an external force is applied to the right side frame 260 of the handheld device, the deformation of the right side frame 260 will directly cause the deformation of the pressure sensor unit, and the pressure sensor unit outputs a pressure signal. The pressure signal is transmitted to the pressure signal processing circuit through contact 262. The contacts 262 are disposed on the inner wall of the side frame of the handheld device by means of fitting and/or embedding.

Optionally, the pressure sensor unit may be disposed on the inner wall of the left side frame and the inner wall of the right side frame of the handheld device in an attaching manner, an embedding manner, or other manners, which is not limited in this embodiment of the present application.

It should be understood that fig. 4 and 5 illustrate a single pressure sensor unit, and of course, two or more pressure sensor units may be disposed in the side frame of the handheld device according to the attaching and embedding method shown in fig. 4 and 5.

As another embodiment, as shown in fig. 6, the second pressure sensor module is disposed on the right side frame 360 of the handheld device in a manner that the pressure sensor unit is disposed on the inner wall of the side frame 360 of the handheld device by a method combining the attaching and the high temperature injection molding. Unlike the previous embodiments, the pressure sensor unit 330 shown in fig. 6 includes a first pressure sensor subunit 331 and a second pressure sensor subunit 332, wherein the first pressure sensor subunit 331 is disposed inside the material of the right side frame 360 of the handheld device by a high temperature injection molding method, and the second pressure sensor subunit 332 is attached to the inner wall of the right side frame 360 of the handheld device by an attaching glue 3312. The first pressure sensor subunit 331 and the second pressure sensor subunit 332 are connected to a contact 362, and the contact 362 is connected to a pressure signal processing circuit. The first pressure sensor sub-unit 331 and the second pressure sensor sub-unit 332 are located at the same position. Optionally, pressure signals output by the two pressure sensor subunits can be superposed at the same position, pressure signals output by the multiple pressure sensor subunits can also be superposed at the same position, and the superposition combination has higher sensitivity to pressure sensing. Specifically, when an external force acts on the right side frame 360 of the handheld device, the deformation of the side frame will simultaneously cause the deformation of the pressure sensor unit, and the pressure sensor unit outputs a pressure signal. At this time, the first pressure sensor unit 331 and the second pressure sensor unit 332 each output one pressure signal, and the output signal is subjected to averaging, median processing, weighting processing, or the like to output a single value as one of data of the multi-dimensional pressure matrix. Compared with a single sensor unit arranged at a single position, the pressure detection precision of the position can be improved by arranging a plurality of sensor subunits at the single position, so that the sensitivity of the pressure detection to pressure sensing is higher. One or more, or even all, of the first pressure sensor unit 31, the second pressure sensor unit 132, the third pressure sensor unit 133, the fourth pressure sensor unit 141, the fifth pressure sensor unit 142, and the sixth pressure sensor unit 143 in the previous embodiment may be the same structure as the pressure sensor unit 330, i.e., the pressure sensor units at different positions may include a plurality of pressure sensor sub-units. The manner of disposing the pressure sensor module in the side frame provided in the embodiment of the present application is only an exemplary illustration, and those skilled in the art can obtain other disposing manners according to the above embodiment without creative efforts.

It should be understood that fig. 6 is an example of two pressure sensor units, and of course, three or more pressure sensor units may also be provided in the handheld device side frame according to the combination method of attaching and embedding shown in fig. 6, and the number of the pressure sensor units provided in the embodiment of the present application is not limited.

The pressure sensor module is arranged in the side frame of the handheld device, and has an invisible key attribute, the waterproof performance of the whole handheld device can be effectively improved by the attribute, the original appearance of the side edge of the handheld device is not changed, and the integral feeling of the handheld device is kept.

As shown in fig. 7, the pressure signal processing circuit 500 includes: a multiplexing switch 510, a pre-buffer 520, an analog-to-digital converter and a power supply module 540, wherein the analog-to-digital converter adopts a high-precision analog-to-digital converter 530.

Specifically, the output end of the power module 540 is connected to the input end of the pressure sensor module 300, and is used for providing power for the pressure sensor module 300; the input end of the multiplexing switch 510 is connected to the output end of the pressure sensor module 300, and is configured to receive one or more pressure signals generated by the pressure sensor module 300 in a time-sharing manner and convert the pressure signals into differential signals; for example, the multiplexing switch 510 receives two pressure signals generated by the first pressure sensor module (left side plate) 300 and the second pressure sensor module (right side plate) 300 in a time sharing manner. The input end of the pre-buffer 520 is connected to the output end of the multiplexing switch 510, and is used for converting the differential signal into a single-ended signal; the input end of the high-precision analog-to-digital converter 530 is connected with the output end of the pre-buffer 520 and is used for quantizing the single-ended signal to generate pressure detection data, and even a weak signal can be identified and quantized; the input end of the handheld device processor module 310 is connected to the output end of the high-precision analog-to-digital converter 530, and is configured to generate and analyze the pressure detection data transmitted by the high-precision analog-to-digital converter 530 into a multidimensional pressure matrix, so as to start a preset function. Specifically, after the pressure sensor module 300 senses pressure deformation, the first pressure sensor module and the second pressure sensor module output a pressure signal of each pressure sensor unit in a time-sharing manner, the multiplexing switch 510 converts a pressure signal into a differential voltage signal for resistance value or capacity value change caused by the deformation and sends the differential voltage signal into the pre-buffer 520, the differential voltage signal is converted into a single-ended voltage signal through the pre-buffer 520, and the single-ended voltage signal is quantized through the high-precision analog-to-digital converter 530 to generate pressure detection data and then sent into the handheld device processor module 310. The multiplex switch can support multiple pressure signals input from the outside, so that the multiple signals share the same hardware processing circuit, and the post-stage circuit architecture is simplified. The high-precision analog-to-digital converter can identify weak signals and quantize the signals, so that the analog-to-digital converter and the amplifier are not required to be added in a circuit, and circuit resources are saved.

Optionally, in this application embodiment, the multiplexing switch may connect two pressure sensor modules, or may be one or more pressure sensor modules, which is not limited in this application embodiment.

Alternatively, the pressure signal processing circuit 500 and the handset processor module 310 may be integrated on a touch chip or a motherboard of the handset, which is not limited in this embodiment.

And sequentially receiving a plurality of pressure detection data according to the time sequence. For example, when the handheld device side frame is squeezed to generate deformation, and the pressure sensor module 300 detects the deformation, a pressure signal is output. For example, the pressure sensor module 300 has 9 pressure sensor units, the pressure sensor module outputs 9 pressure signals, the pressure signal processing circuit outputs pressure detection data, that is, the time-sharing output of the 9 pressure detection data, and the handset processor module 310 receives the 9 pressure detection data of the pressure signal processing circuit.
