[0002] With the improvement of user demand, the screen ratio of the terminal equipment is getting larger and larger. The larger screen ratio can provide better operation interface and visual experience for the user. In order to further increase the display area of the terminal equipment, the double-sided screen terminal equipment emerges as the times require, that is, the front and back sides of the terminal equipment are both provided with display screens, which greatly compresses the stacking space of the terminal equipment in the thickness direction (i.e. the direction perpendicular to the display screen).

[0003] With the improvement of user demand, the terminal equipment has more and more functions, and the infrared sensing function is a more practical function, which can realize distance detection, proximity detection, ambient light detection and other functions. Since the display screen is arranged on both sides, the terminal equipment has independent application scenarios on both sides, and under the premise of configuring the infrared sensing function, the terminal equipment has the need to configure infrared sensing on both sides. Based on this, in the current terminal equipment, infrared sensors are arranged on both sides of the terminal equipment, so as to realize the respective infrared sensing on both sides.

[0004] Since the stacking space in the thickness direction of the double-sided screen terminal equipment is relatively cramped, configuring infrared sensors on both sides of the terminal equipment will inevitably occupy a large space, making the stacking of the terminal equipment in the thickness direction more difficult. Of course, it is not limited to the double-sided screen terminal equipment, other terminal equipment may also have the need to arrange infrared sensors on both sides, and with the development of the light and thin direction of the terminal equipment, arranging infrared sensors on both sides of the terminal equipment will still make the thickness of the terminal equipment larger.

[0036] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions will be described below in connection with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0037] The technical solutions disclosed by the various embodiments of the present application will be described in detail below in connection with the drawings.

[0038] Reference should be made to Figures 1-5 The embodiments of the present application disclose an infrared sensing module, which can be applied to a terminal device. The disclosed infrared sensing module comprises a reflecting part 200, a driving part 300, an infrared light emitter 400 and an infrared light receiver 500.

[0039] The infrared light emitter 400 is used for emitting infrared light, and the infrared light receiver 500 is used for receiving infrared light. The reflecting part 200 is used for reflecting infrared light. The infrared light emitted by the infrared light emitter 400 can change the projection direction after being reflected by the infrared reflecting layer 220 of the reflecting part 200.

[0040] The driving part 300 is connected with the reflecting part 200, and the driving part 300 can drive the reflecting part 200 to rotate, so as to adjust the working position of the reflecting part 200. In the case that the reflecting part 200 rotates to a preset position, the infrared reflecting layer 220 of the reflecting part 200 faces the infrared light emitter 400 and the infrared light receiver 500, so as to be capable of reflecting infrared light.

[0041] In the specific working process, the driving part 300 drives the reflecting part 200 to rotate, so that the position of the reflecting part 200 can be changed, and the reflecting part 200 can work at multiple positions. In the process of infrared detection, the driving part 300 drives the reflecting part 200 to rotate to a preset position, in this case, the infrared light emitted by the infrared light emitter 400 can be projected onto the infrared reflecting layer 220 of the reflecting part 200, and under the reflection of the infrared reflecting layer 220, the infrared light can be projected onto the detected object (for example, a human face), and the infrared light reflected by the detected object can be reflected to the infrared light receiver 500 by the infrared reflecting layer 220. In this process, the detection result can be obtained by processing the amount of infrared light emitted by the infrared light emitter 400 and the amount of infrared light received by the infrared light receiver 500. The process and principle of detecting by using infrared light are known technologies, and will not be described here.

[0042] In the infrared sensing module disclosed in the embodiment of the present application, the driving part 300 can drive the reflecting part 200 to rotate, and when the reflecting part 200 rotates to a preset position, the infrared reflecting layer 220 of the reflecting part 200 can be directed towards the infrared light emitter 400 and the infrared light receiver 500, so that the infrared reflecting layer 220 works. Since the reflecting part 200 can rotate, the infrared detection at multiple positions can be realized. The infrared sensing module with this structure can be applied to a terminal device to realize infrared detection in multiple directions of the terminal device. In this case, the terminal device only needs to be provided with one infrared sensing module to realize infrared detection in at least two directions, and does not need to be provided with infrared sensors in each detection direction, thereby reducing the stacking and facilitating the reduction of the thickness of the terminal device.

[0043] In the embodiment of the present application, the preset position is at least two. In a specific embodiment, the preset position is two. When the preset position is two, the infrared sensing module is arranged inside the terminal device, and infrared detection can be realized on both sides of the terminal device.

[0044] In order to facilitate assembly, in a more preferred scheme, the disclosed infrared sensing module can further include a circuit board 600. The infrared light emitter 400 and the infrared light receiver 500 are arranged on the circuit board 600, and the infrared light emitter 400 and the infrared light receiver 500 are electrically connected with the circuit board 600. In this case, the infrared light emitter 400 and the infrared light receiver 500 can be first mounted on the circuit board 600, which is conducive to the modularization of the infrared sensing module, and the above assembly structure is more conducive to the installation of the infrared light emitter 400 and the infrared light receiver 500 in the terminal device. In the preferred scheme, the infrared light emitter 400 and the infrared light receiver 500 can be arranged at intervals, thereby avoiding the influence between each other.

[0045] In the embodiment of the present application, the structure of the reflecting part 200 can be various, and the reflecting part 200 can be a common reflecting structure, for example, the reflecting part 200 can be a plane mirror. Of course, the reflecting part 200 can also be other structures, please refer to Figure 5 The reflecting part 200 disclosed in the embodiment of the present application can include a base part 210 and an infrared reflecting layer 220 arranged on the base part 210, and the driving part 300 is drivingly connected with the base part 210. The infrared reflecting layer 220 is used for reflecting infrared light.

[0046] When the terminal device does not perform infrared detection, the reflecting part 200 does not need to reflect the infrared light out of the terminal device. Based on this, the base part 210 can be provided with an infrared absorbing layer 230, and the driving part 300 can drive the reflecting part 200 to rotate to a position (i.e. a third position) at which the infrared absorbing layer 230 is opposite to the infrared light emitter 400, so that the infrared absorbing layer 230 can absorb the infrared light emitted by the infrared light emitter 400, thereby avoiding the infrared light from being projected out of the first light transmission hole 120 or the second light transmission hole 130. Of course, the infrared light emitter 400 can also be not turned off, and the control module of the terminal device can control the infrared light emitter 400 and the infrared light receiver 500 to stop working.

[0047] The structure of the base part 210 can be various, in order to make the base part 210 stay at the non-working position more conveniently, the surface of the base part 210 can include a straight surface and a curved surface connected with the straight surface, the infrared reflecting layer 220 is arranged on the straight surface, the infrared absorbing layer 230 is arranged on the curved surface, each part of the curved surface is located in the same cylindrical surface, and the area of the base part 210 located at the center of the cylindrical surface is drivingly connected with the driving part 300. In this case, the center of gravity of the base part 210 is more likely to make the reflecting part 200 stay at the position at which the infrared absorbing layer 230 is opposite to the infrared light emitter 400.

[0048] The infrared absorbing layer 230 and the infrared reflecting layer 220 are both coating or film, and the embodiment of the present application does not limit the specific structure of the infrared absorbing layer 230 and the infrared reflecting layer 220.

[0049] Based on the infrared sensing module disclosed in the embodiment of the present application, the embodiment of the present application discloses a terminal device, and the disclosed terminal device includes a shell 100 and the infrared sensing module described in the above embodiment. The infrared sensing module is arranged in the shell 100.

[0050] The shell 100 is a basic component of the terminal device, and the shell 100 can provide a mounting basis for other components of the terminal device. The shell 100 has an inner cavity 110, and in the embodiment of the present application, the reflecting part 200, the driving part 300, the infrared light emitter 400 and the infrared light receiver 500 are all arranged in the inner cavity 110.

[0051] In this embodiment of the invention, a first light-transmitting hole 120 and a second light-transmitting hole 130 are respectively provided on opposite sides of the housing 100. The first light-transmitting hole 120 and the second light-transmitting hole 130 face opposite directions, and both the first light-transmitting hole 120 and the second light-transmitting hole 130 can transmit light into the inner cavity 110. Of course, according to the principle of optical path reversibility, light in the inner cavity 110 can also be projected out of the housing 100 through the first light-transmitting hole 120 and the second light-transmitting hole 130. In this case, there can be two preset positions, namely a first position and a second position.

[0052] Infrared light emitted by the infrared emitter 400 is reflected by the reflector 200 and then emitted through the first light-transmitting hole 120 or the second light-transmitting hole 130 to the outside of the housing 100. The infrared light projected outside the housing 100 passes the object being detected and then enters the housing 100 through the first light-transmitting hole 120 or the second light-transmitting hole 130. It is then reflected by the reflector 200 to the infrared receiver 500, ultimately achieving detection through the difference in infrared light. Specifically, the drive unit 300 drives the reflector 200 to rotate, so that the reflector 200 switches between engaging with the first light-transmitting hole 120 and the second light-transmitting hole 130.

[0053] like Figure 2 As shown, when the reflector 200 is rotated to the first position, the infrared light emitted by the infrared emitter 400 is reflected by the reflector 200 and emitted from the first light-transmitting hole 120. After the infrared light is reflected by the object being detected, the reflector 200 reflects the infrared light from the outside of the terminal device through the first light-transmitting hole 120 to the infrared receiver 500. This process enables infrared detection to be performed on one side of the terminal device.

[0054] like Figure 3 As shown, when the reflector 200 is rotated to the second position, the infrared light emitted by the infrared emitter 400 is reflected by the reflector 200 and emitted from the second light-transmitting hole 130. After the infrared light is reflected by the object being detected, the reflector 200 reflects the infrared light to the infrared receiver 500. This process enables infrared detection to be performed on the other side of the terminal device.

[0055] The terminal device disclosed by the embodiment of the present application can drive the reflection part 200 to rotate by the driving part 300, so that the reflection part 200 can be rotated to the first position or the second position, and the first light-transmitting hole 120 and the second light-transmitting hole 130 can be cooperated with each other in different positions, so that the infrared light emitter 400 and the infrared light receiver 500 can be cooperated with the first light-transmitting hole 120 in one position of the reflection part 200 and can be cooperated with the second light-transmitting hole 130 in another position. In this case, only one set of infrared light emitter 400 and infrared light receiver 500 needs to be arranged in the terminal device, so that the infrared detection function can be realized on both sides of the terminal device. Compared with the current terminal device in which the infrared detection components are arranged on both sides, the number of the infrared detection components can be reduced, the space in the shell 100 can be reduced, and the thickness of the terminal device can be reduced.

[0056] Meanwhile, the reduction of the infrared detection components can reduce the manufacturing cost of the terminal device and simplify the structure of the terminal device.

[0057] As described above, the first light-transmitting hole 120 and the second light-transmitting hole 130 are arranged on the opposite sides of the shell 100. In general, the terminal device includes the first screen assembly 700, and the first light-transmitting hole 120 can be arranged on the side of the shell 100 on which the first screen assembly 700 is arranged. The first screen assembly 700 includes the first light-transmitting area arranged on the first light-transmitting hole 120. Specifically, the first screen assembly 700 can include the first light-transmitting cover plate including the first light-transmitting area, and the first light-transmitting area of the first light-transmitting cover plate is arranged on the first light-transmitting hole 120. The first light-transmitting area can also cover the first light-transmitting hole 120 without affecting the light transmission of the first light-transmitting hole 120, so that the dustproof and waterproof effects can be achieved.

[0058] Under the premise that the terminal device is a single-screen terminal device, the second light-transmitting hole 130 can be arranged on the side of the shell 100 on which the battery cover is arranged.

[0059] In order to increase the display area of the terminal device, in a more preferred solution, the terminal device can further include the second screen assembly 800, and the first screen assembly 700 and the second screen assembly 800 can be arranged on the two sides of the shell 100, respectively. In this case, the terminal device is a double-screen terminal device, and the double-screen terminal device includes the first screen assembly 700 and the second screen assembly 800, so that the display area of the terminal device can be increased, and the display performance of the terminal device can be improved.

[0060] Specifically, the second screen assembly 800 can include a second light-transmitting area covering the second light-transmitting hole 130. Generally, the second screen assembly 800 includes a second light-transmitting cover plate, the second light-transmitting cover plate includes the second light-transmitting area, and the second light-transmitting area of the second light-transmitting cover plate covers the second light-transmitting hole 130. The second light-transmitting area can also cover the second light-transmitting hole 130 without affecting the light transmission of the second light-transmitting hole 130, thereby achieving the effects of dustproof and waterproof.

[0061] The terminal device disclosed in the embodiments of the present application can be a smart phone, a tablet computer, a wearable device, an electronic book reader, or the like. The embodiments of the present application do not limit the specific type of the terminal device.

[0062] Based on the terminal device disclosed in the embodiments of the present application, the embodiments of the present application disclose a control method of a terminal device. The disclosed control method includes the following steps.

[0063] Step one, driving the reflection part 200 to rotate by the driving part 300.

[0064] In this step, the driving part 300 can be controlled to drive the reflection part 200 to rotate cyclically.

[0065] Step two, determining whether the intensity of the infrared signal received by the infrared light receiver 500 meets a preset condition.

[0066] Due to the rotation of the reflection part 200, the infrared light emitted by the infrared light emitter 400 can be emitted from the first light-transmitting hole 120 and the second light-transmitting hole 130 through the reflection part 200. The detected object can be on the side facing the first light-transmitting hole 120 or the side facing the second light-transmitting hole 130. The infrared light projected outside the shell 100 is reflected after encountering the detected object, and finally reflected to the infrared light receiver 500 through the first light-transmitting hole 120 or the second light-transmitting hole 130. Of course, when the infrared light does not encounter the detected object, the amount of infrared light reflected back into the shell 100 is small. Therefore, the position of the detected object can be determined according to the intensity of the infrared signal received by the infrared light receiver 500.

[0067] Step three, fixing the position of the reflection part 200 when the intensity of the infrared signal meets the preset condition.

[0068] In this step, when the intensity of the infrared signal meets the preset condition, it means that there is a detected object. In this case, the position of the reflection part 200 is fixed. Specifically, the driving part 300 can be controlled to stop driving the reflection part 200, so that the position of the reflection part 200 is fixed.

[0069] Generally, the terminal device does not perform infrared detection in the idle state, in order to achieve more efficient control, in a more preferred embodiment, the terminal device can include a gravity sensor; under the premise that the terminal device includes a gravity sensor, step one can also include:

[0070] Step A, detecting the signal change of the gravity sensor of the terminal device.

[0071] Step B, when the signal of the gravity sensor changes, controlling the driving part 300 to turn on.

[0072] Generally, when the user picks up the terminal device, the signal detected by the gravity sensor will change, and under this condition, the driving part 300 is controlled to turn on.

[0073] Based on the control method disclosed in the embodiment of the present application, the embodiment of the present application discloses a control device of a terminal device, the disclosed control device can include:

[0074] The first control module is used to control the driving part 300 to drive the reflection part 200 to rotate.

[0075] The judgment module is used to judge whether the intensity of the infrared signal received by the infrared light receiver 500 meets the preset condition;

[0076] The second control module fixes the position of the reflection part 200 when the intensity of the infrared signal meets the preset condition.

[0077] The embodiment of the present application discloses a terminal device, the disclosed terminal device includes a processor, a memory and a computer program stored on the memory and executable on the processor, when the computer program is executed by the processor, the control method described above is realized.

[0078] The embodiment of the present application discloses a computer readable storage medium, the computer readable storage medium stores a computer program, when the computer program is executed, the control method described above is realized.

[0079] The difference between the embodiments is mainly described in the above embodiments of the present application, the optimization features different between the embodiments can be combined to form a more optimal embodiment as long as they are not contradictory, considering the brevity of the text, it will not be repeated here.

[0080] The above only describes the embodiments of the present application and is not used to limit the present application. The present application can have various changes and variations for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the scope of claims of the present application.
