Description

Technical Field

[0001] The present invention relates to the technical field of folding screen terminals, and in particular to a folding state detection device, method and folding screen terminal for a folding screen terminal. Background Art

[0002] Mobile terminals have entered the 5G era. People have been exploring, updating and iterating on the innovation of terminals. In recent years, the application of flexible screen and folding screen technologies on mobile terminals has brought people a brand-new experience. The folding screen expands the screen area of the mobile terminal. Especially for mobile phone terminals, it can enable the mobile terminal screen to achieve a larger space expansion and content display.

[0003] For a folding screen terminal, there are two states: the folding state and the unfolded state. When in the folding state, the outer screen is used for work, and when in the unfolded state, the folded inner screen is used for work. Since the screen sizes and ratios of the outer screen and the inner screen are different, the display adaptability of the application program in the folding state and the unfolded state of the folding screen is very important for the user experience. Therefore, it is necessary to be able to detect and judge the folding and unfolding states of the folding screen terminal.

[0004] For the detection and judgment of the folding and unfolding states of a folding screen terminal, the existing technology is to set sensors on both sides of the folding screen, and determine the folding and unfolding states of the two sides of the screen through data measurement and data communication between the sensors. However, setting multiple groups of sensors not only has a high cost, but also the sensor devices will interfere with each other, affecting calibration. Summary of the Invention

[0044] The present invention designs a detection device that can move with the hinge by utilizing the movement of the hinge of a foldable screen terminal, and obtains a detection result through a detection circuit, so that the display adaptation of the application program can be adjusted according to the detection result. Specific embodiments are described as follows.

[0045] Please refer to Figure 1 , which is a schematic cross-sectional structure diagram of the unfolded state of the foldable screen terminal in this embodiment. The foldable screen terminal includes a hinge assembly 10, a foldable screen 20, a housing 30, a folding state detection device 40, a power supply (not shown in the figure), and a control unit (not shown in the figure). Among them, the hinge assembly 10 is used to unfold and fold the foldable screen terminal. The foldable screen 20 covers the side of the housing 30. The housing 30 is used to accommodate the hinge assembly 10, the folding state detection device 40, and the power supply. The folding state detection device 40 is connected to the hinge assembly 10 to detect the unfolded and folded states of the foldable screen 20. The power supply is used to supply power to the folding state detection device 40. The control unit is used to obtain the detection signal of the folding state detection device 40.

[0046] Specifically, the hinge assembly 10 includes a hinge rotating shaft 11 and two hinge swinging blades 12. Among them, the two hinge swinging blades 12 can rotate relative to each other with the hinge rotating shaft 11 as the axis.

[0047] The foldable screen 20 is an electronic screen that can be bent. The center line of the foldable screen 20 is opposite to the hinge rotating shaft 11. The foldable screen 20 is arranged parallel to the two hinge swinging blades 12. That is, when the hinge swinging blades 12 rotate, the foldable screen 20 unfolds or folds along this center line as a fold line. Please also refer to Figure 2 and Figure 3 , Figure 2 which is a schematic cross-sectional structure diagram of the intermediate state of the foldable screen terminal in this embodiment; Figure 3 which is a schematic cross-sectional structure diagram of the folded state of the foldable screen terminal in this embodiment. The foldable screen terminal includes three states: the unfolded state, the intermediate state, and the folded state. When the foldable screen terminal is in the unfolded state, the foldable screen 20 is a flat surface; when the foldable screen terminal is in the intermediate state, the foldable screen 20 faces the display surface for displaying images and is in a bent shape; when the foldable screen terminal is in the folded state, the foldable screen 20 is in a half-folded state.

[0048] The housing 30 is a semi-open structure, and the opening of the housing 30 is fixedly connected to the edge of the foldable screen 20. More specifically, the housing 30 can be cut into a first housing 31 and a second housing 32 along the vertical center line of the side opposite to the foldable screen 20. The first housing 31 and the second housing 32 are connected by a flexible housing 33. When the foldable screen terminal is in the unfolded state, the first housing 31 and the second housing 32 can be in direct contact; when the foldable screen terminal is in the intermediate state and the folded state, the first housing 31 and the second housing 32 will separate as the foldable screen 20 moves, and the flexible housing 33 will gradually unfold.

[0049] Please refer to Figure 4 Figure 4 , which is the schematic diagram of the detection circuit of the folding state detection device. The folding state detection device 40 includes a first base substrate 42, a second base substrate 43, a conductor probe 44, a connecting member 45, a first resistor 46, and a second resistor 47. Among them, the first base substrate 42 is a conductor, which is arranged on one side close to the folding screen 20 and opposite to the folding line of the folding screen 20; the second base substrate 43 is a conductor, which is arranged on one side close to the housing 30 and opposite to the first base substrate 42; the conductor probe 44 is arranged between the first base substrate 42 and the second base substrate 43, and both ends of the conductor probe 44 are opposite to the first base substrate 42 and the second base substrate 43, and the conductor probe 44 is electrically connected to the power supply; there are two connecting members 45. One end of one connecting member 45 is respectively movably connected to a hinge flap 12 and the conductor probe 44, and can relatively rotate with the hinge flap 12 and the conductor probe 44 respectively. The two ends of the other connecting member 45 are respectively movably connected to another hinge flap 12 and the conductor probe 44, and can relatively rotate with the hinge flap 12 and the conductor probe 44 respectively; one end of the first resistor 46 is electrically connected to the first base substrate 42, and the other end is electrically connected to the power supply. The conductor probe 44, the first base substrate 42, the first resistor 46, and the power supply form a first detection circuit; one end of the second resistor 47 is electrically connected to the second base substrate 43, and the other end is electrically connected to the power supply. The conductor probe 44, the second base substrate 43, the second resistor 47, and the power supply form a second detection circuit.

[0050] The control unit is electrically connected to the first resistor 46 and the second resistor 47, and is used to obtain a detection signal according to the current or voltage of the first resistor 46 and the second resistor 47. When there is current or voltage on the first resistor 46, the detection signal is that the folding screen terminal is in the unfolded state; when there is current or voltage on the second resistor 47, the detection signal is that the folding screen terminal is in the folded state; when there is no current or voltage on both the first resistor 46 and the second resistor 47, the detection signal is that the folding screen terminal is in the intermediate state.

[0051] The working principle of the folding state detection device 40 for detecting the folding state of the folding screen terminal is: when the folding screen terminal is in the unfolded state, the conductor probe 44 contacts the first base substrate 42, and at this time the first detection circuit is turned on, that is, current passes through the first resistor 46, and a signal that the folding screen terminal is in the unfolded state can be obtained by detecting the current or voltage of the first resistor 46; when the folding screen terminal is in the intermediate state from the unfolded state to the folded state, the hinge leaf 12 rotates, and the conductor probe 44 is linked through the connecting piece 45, and the conductor probe 44 leaves the first base substrate 42 and does not reach the second base substrate 43. At this time, the first detection circuit and the second detection circuit are both disconnected, that is, no current passes through the first resistor 46 and the second resistor 47, and the signal that the folding screen terminal is in the unfolded state can be obtained by detecting the current or voltage of the first resistor 46. The current or voltage of the second resistor 47 can obtain a signal that the folding screen terminal is in an intermediate state; when the folding screen terminal is in a folded state, the conductor probe 44 contacts the second base substrate 43, and the second detection circuit is turned on. That is, current passes through the second resistor 47, and the signal that the folding screen terminal is in a folded state can be obtained by detecting the current or voltage of the second resistor 47; similarly, when the folding screen terminal is in an intermediate state from a folded state to an unfolded state, the hinge leaf 12 rotates, and the conductor probe 44 is linked through the connector 45, and the conductor probe 44 leaves the second base substrate 43. At this time, the first detection circuit and the second detection circuit are both disconnected, and the signal that the folding screen terminal is in an intermediate state can be obtained by detecting the current or voltage of the first resistor 46 and the second resistor 47.

Figure 6Schematic diagram of the detection circuit of the folding state detection device for an alternative embodiment. In an alternative embodiment, the folding state detection device 40 includes a first base substrate 42, a conductor probe 44, a connecting member 45, and a first resistor 46. Among them, the first base substrate 42 is a conductor, which is arranged on one side close to the folding screen 20 and opposite to the folding line of the folding screen 20; the conductor probe 44 is arranged on the side of the first base substrate 42 facing away from the folding screen 20. One end of the conductor probe 44 is vertically opposite to the first base substrate 42, and the conductor probe 44 is electrically connected to the power supply; there are two connecting members 45. One end of one connecting member 45 is respectively movably connected to a hinge flap 12 and the conductor probe 44, and can relatively rotate with the hinge flap 12 and the conductor probe 44 respectively. The two ends of the other connecting member 45 are respectively movably connected to another hinge flap 12 and the conductor probe 44, and can relatively rotate with the hinge flap 12 and the conductor probe 44 respectively; one end of the first resistor 46 is electrically connected to the first base substrate 42, and the other end is electrically connected to the power supply. The conductor probe 44, the first base substrate 42, the first resistor 46, and the power supply form a first detection circuit.

[0053] In this alternative embodiment, the folding state of the folding screen terminal can be detected by detecting the current or voltage on the first resistor 46. When it is detected that there is current or voltage on the first resistor 46, a signal that the folding screen terminal is in the unfolded state can be obtained; when it is detected that there is no current or voltage on the first resistor 46, a signal that the folding screen terminal is in a non-unfolded state, that is, an intermediate state or a folded state, can be obtained.

[0054] Please refer to Figure 7 and Figure 8 , Figure 7 Schematic cross-sectional structure diagram of the unfolded state of the folding screen terminal for another alternative embodiment, Figure 8Schematic diagram of the detection circuit of the folding state detection device for an optional embodiment. In another optional embodiment, the folding state detection device 40 includes a second base substrate 43, a conductor probe 44, a connecting member 45, and a second resistor 47. Among them, the second base substrate 43 is a conductor, which is arranged on one side close to the housing 30 and opposite to the folding line of the folding screen 20; the conductor probe 44 is arranged on the side of the second base substrate 43 facing the folding screen 20. One end of the conductor probe 44 is vertically opposite to the second base substrate 43, and the conductor probe 44 is electrically connected to the power supply; there are two connecting members 45. One end of one connecting member 45 is respectively movably connected to a hinge swing blade 12 and the conductor probe 44, and can relatively rotate with the hinge swing blade 12 and the conductor probe 44 respectively. The two ends of the other connecting member 45 are respectively movably connected to another hinge swing blade 12 and the conductor probe 44, and can relatively rotate with the hinge swing blade 12 and the conductor probe 44 respectively; one end of the second resistor 47 is electrically connected to the second base substrate 43, and the other end is electrically connected to the power supply. The conductor probe 44, the second base substrate 43, the second resistor 47, and the power supply form a second detection circuit.

[0055] In this optional embodiment, the folding state of the folding screen terminal can be detected by detecting the current or voltage on the second resistor 47. When it is detected that there is current or voltage on the second resistor 47, a signal that the folding screen terminal is in the folding state can be obtained; when it is detected that there is no current or voltage on the second resistor 47, a signal that the folding screen terminal is in the non-folding state, that is, the intermediate state or the unfolded state, can be obtained.

[0056] Compared with the prior art, the folding state detection device 40 of the present invention changes the position of the conductor probe 44 by moving with the hinge assembly. The first base substrate 42 and the second base substrate 43 are respectively arranged at the positions where the conductor probe 44 is located when the folding screen terminal is in the folding state and the unfolded state. When the folding screen terminal is in different states, the contact and separation of the conductor probe 44 with the first base substrate 42 and the second base substrate 43 are used to control the on and off of the two detection circuits, so as to change the current or voltage state of the first resistor 46 and the second resistor 47, as an indication signal of different states of the folding screen terminal, which can accurately detect the unfolded state of the folding screen terminal and has a low production cost.

[0057] Based on the above embodiment of the folding screen terminal, the present invention also provides a method for detecting the unfolded state of a folding screen terminal. This detection method can be implemented by running a computer program by a controller of the control unit of the folding screen terminal. This detection method includes the steps of:

[0058] Real-time detect the current or voltage of the first resistor 46 and the second resistor 47 in the folding state detection device 40;

[0059] When current or voltage is detected in the first resistor 46, a folding interrupt is triggered as a status report;

[0060] When current or voltage is detected in the second resistor 47, an unfolding interrupt is triggered as a status report;

[0061] The display mode of the folding screen terminal is adaptively adjusted according to the status report.

[0062] In a specific implementation, the adaptive adjustment of the display of the folding screen terminal according to the status report includes:

[0063] When it is detected that there is no current or voltage in both the first resistor 46 and the second resistor 47, and the most recent status report is a folding interrupt, the folding screen terminal is adjusted to a display mode adapted to the unfolded state;

[0064] When it is detected that there is no current or voltage in both the first resistor 46 and the second resistor 47, and the most recent status report is an unfolding interrupt, the folding screen terminal is adjusted to a display mode adapted to the folded state.

[0065] In another specific implementation, the adaptive adjustment of the display of the folding screen terminal according to the status report includes:

[0066] When a folding interrupt is triggered as a status report, the folding screen terminal is adjusted to a display mode adapted to the folded state;

[0067] When an unfolding interrupt is triggered as a status report, the folding screen terminal is adjusted to a display mode adapted to the unfolded state.

[0068] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and the present invention also intends to include these changes and modifications.
