Fig. 1 to 4 show a foldable electronic device 100 folded outwards. The illustrated foldable electronic device 100 includes a first casing 100a, a second casing 100b, and a display screen 140, the display screen 140 is disposed on an outer surface of the first casing 100a and an outer surface of the second casing 100b, and the first casing 100a and the second casing 100b are foldable outward about a folding axis O1O 2. The foldable electronic device 100 that is folded outward can be generally divided into three states, and the foldable electronic device 100 shown in fig. 2 is folded from the unfolded state in the folding direction to the stand state, and is further folded from the stand state in the folding direction to the folded state.

When the foldable electronic device 100 in the unfolded state is folded in the reverse folding direction (opposite to the folding direction) shown in fig. 3 due to an incorrect operation (i.e., the reverse folding state), the display screen 140 is easily damaged due to being crushed, as shown in fig. 3 and 4.

When the foldable electronic device 100 in the unfolded state is folded in the reverse folding direction (opposite to the folding direction) shown in fig. 7 due to an incorrect operation (i.e., the reverse folding state), the display screen 140 is lifted by other components of the electronic device 100, and a bulge is likely to occur, as shown in fig. 7 and 8.

Example one

Referring to fig. 10 to 12, fig. 10 illustrates a front perspective view of a foldable electronic device 100; fig. 11 shows a rear view of a foldable electronic device 100; fig. 12 is a schematic cross-sectional view of section C-C in fig. 11. The foldable electronic device 100 shown in the figure includes a first casing 100A, a second casing 100b, a display screen 140 and a pressure sensor 180A, wherein the display screen 140 is disposed on an inner surface of the first casing 100A and an inner surface of the second casing 100b, and the first casing 100A and the second casing 100b can be folded around a folding axis O1O2 in a folding direction. The first casing 100A is provided with a mounting hole 101 at a portion close to the second casing 100b, and the pressure sensor 180A is provided in the mounting hole 101.

In the process of the foldable electronic device 100 from the unfolded state to the folded state according to the folding direction, as shown in fig. 13, the pressure sensor 180A of the mounting hole 101 gradually separates from the second casing 100b, and the first casing 100A is not pressed by the second casing 100 b. However, when the foldable electronic device 100 is turned from the unfolded state to the unfolded state in the unfolded direction due to an erroneous operation, as shown in fig. 14, the second housing 100b presses the first housing 100A and also presses the pressure sensor 180A provided in the mounting hole 101.

It should be noted that, in the drawings, the mounting hole 101 is disposed on the first casing 100a for example, in some embodiments of the present application, the mounting hole 101 may also be disposed on the second casing 100b, and the structure disposed on the second casing 100b is similar to the structure disposed on the first casing 100a, and is not described herein again.

As can be seen from the above description, when the electronic device 100 is folded in the reverse folding direction due to an erroneous operation, the first casing 100a and the second casing 100b have a structure pressed against each other, and by collecting the pressure of the structure, it can be determined whether the foldable electronic device 100 is in the reverse folding state. Based on this, the pressure sensor 180A detects a pressure signal resulting from the presence of mutual pressing of the first casing 100A and the second casing 100 b. The foldable electronic device 100 may determine whether the foldable electronic device 100 is in the unfolded state based on the pressure signal detected by the pressure sensor 180A.

In some embodiments, the cable of the pressure sensor 180A is electrically connected to the processor 110, the pressure sensor 180A detects a pressure signal applied to the first housing 100A by the second housing 100b and transmits the pressure signal to the processor 110, the processor 110 obtains pressure data from the pressure signal, compares the pressure data with a first threshold, and when the pressure data is greater than the first threshold, it indicates that the foldable electronic device 100 is in the reverse-folding state, and the processor 110 controls the display screen 140 to display the reminder data, controls the speaker to broadcast the reminder data, or controls the micro motor to perform alarm vibration.

The operation of the pressure sensor 180A is described further below with reference to fig. 13-14.

Referring to fig. 13, in the process that the foldable electronic device 100 is folded from the unfolded state to the folded state according to the foldable direction, the second housing 100b is not in contact with the first housing 100A, and the pressure sensor 180A does not detect a pressure signal, which indicates that the foldable electronic device 100 is not in the reverse folding state, and the processor 110 does not control the display screen 140 to display the reminding data, control the speaker to broadcast the reminding data, or control the micro motor to perform alarm vibration.

Referring to fig. 14, in the process that the foldable electronic device 100 is folded from the unfolded state to the unfolded state according to the unfolding direction, the second housing 100b extrudes the first housing 100A, the pressure sensor 180A detects a pressure signal between the first housing 100A and the second housing 100b, the processor 110 obtains pressure data from the pressure signal, compares the pressure data with a first threshold value, and when the pressure data is greater than the first threshold value, it indicates that the foldable electronic device 100 is in the unfolded state, and the processor 110 controls the display screen 140 to display the reminding data, controls the speaker to broadcast the reminding data, or controls the micro motor to perform alarm vibration according to the pressure signal.

In the above embodiment, the pressure receiving face of the pressure sensor 180A is exposed from the mounting hole 101, and can directly detect the pressure signal between the first casing 100A and the second casing 100 b. In the illustration, the pressure-bearing surface of the pressure sensor 180A is a flat surface, and in some examples of the invention, the pressure-bearing surface of the pressure sensor 180A may also be a curved surface, such as a spherical surface, a conical surface, etc. in the curved surface. The mounting hole 101 is disposed at a position of the first casing 100a close to the second casing 100b, specifically, at an end surface of the first casing 100a, when the foldable electronic device 100 is in the unfolded state, the end surface of the first casing 100a corresponds to the end surface of the second casing 100 b; in the process of folding the foldable electronic device 100 from the unfolded state to the folded state in the folding direction, the end face of the first housing 100a and the end face of the second housing 100b are away from each other.

It should be noted that the pressure sensor 180A may also indirectly detect a pressure signal between the first casing 100A and the second casing 100 b. In some embodiments of the present application, referring to fig. 15 to 16, a sealing head 102 is slidably mounted at a position of the mounting hole 101 near the second casing 100b, a pressure-bearing surface of the sealing head 102 exposes the mounting hole 101, and a pressure-bearing surface of the pressure sensor 180A is disposed opposite to the sealing head 102, and a sealed cavity 101a is formed therebetween. In the process of the electronic device 100 being folded from the unfolded state to the folded state according to the folding direction, the blocking head 102 and the second casing 100b are gradually separated, and the first casing 100a is not pressed by the second casing 100 b. However, when the foldable electronic device 100 is turned from the unfolded state to the unfolded state in the unfolding direction due to an erroneous operation, the second housing 100b presses the first housing 100A and also presses the pressure-bearing surface of the plugging head 102 disposed in the mounting hole 101, the plugging head 102 slides in the mounting hole 101 to compress the gas in the sealed cavity 101a, the pressure of the compressed gas increases, and the pressure sensor 180A detects a gas pressure signal.

It should be noted that, in the drawings, the pressure-bearing surface of the plugging head 102 is a flat surface, and in some examples of the present invention, the pressure-bearing surface of the plugging head 102 may also be a curved surface, such as a spherical surface or a conical surface in a curved surface. When the foldable electronic device 100 is turned over in the reverse folding direction due to an incorrect operation, the plugging head 102 senses the extrusion of the second housing 100b first, and slides in the direction close to the pressure sensor 180A under the extrusion to compress the gas in the sealed cavity 101a (the volume of the sealed cavity 101a becomes smaller), and the pressure detected by the pressure sensor 180A becomes larger on the premise that the area of the pressure-bearing surface of the pressure sensor 180A is not changed. In the illustration, a sealed cavity 101a exists between the pressure sensor 180A and the blocking head 102, that is, the pressure received by the blocking head 102 compresses the gas in the sealed cavity 101a, and the pressure-bearing surface of the pressure sensor 180A detects the pressure of the gas in the sealed cavity 101a, that is, the pressure-bearing surface of the pressure sensor 180A does not directly contact with the second casing 100 b. The pressure sensor 180A adopting such a structural form is compact in structure and small in occupied volume.

The blocking head 102 is made of soft rubber, and when the second shell 100b presses the first shell 100a, the second shell 100b is in soft contact with the pressure-bearing surface of the blocking head 102, so that noise can be reduced.

The operation of the pressure sensor 180A is described further below with reference to fig. 15-16.

Referring to fig. 15, in the process that the foldable electronic device 100 is folded from the unfolded state to the folded state according to the foldable direction, the second housing 100b is not in contact with the first housing 100A, the pressure sensor 180A does not output a pressure signal, which indicates that the foldable electronic device 100 is not in the reverse folding state, and the processor 110 does not control the display screen 140 to display the reminding data, control the speaker to broadcast the reminding data, or control the micro motor to perform alarm vibration.

Referring to fig. 16, in the process that the foldable electronic device 100 is turned from the unfolded state to the unfolded state according to the unfolding direction, the second housing 100b presses the plugging head 102 at the first housing 100A, the plugging head 102 slides in the direction close to the pressure sensor 180A, the volume of the sealed cavity 101a decreases, the pressure sensor 180A detects a pressure signal transmitted by the plugging head 102 to the pressure-bearing surface of the pressure sensor 180A through the compressed gas in the sealed cavity 101a, the processor 110 obtains pressure data from the pressure signal, compares the pressure data with a first threshold value, and when the pressure data is greater than the first threshold value, it indicates that the foldable electronic device 100 is in the unfolded state, and the processor 110 controls the display screen 140 to display the reminding data, controls the speaker to broadcast the reminding data, or controls the micro motor to perform alarm vibration according to the pressure signal.

As described above in the context of the hardware components of the electronic device 100, the pressure sensor 180A in the present embodiment may be a gauge pressure sensor, a micro pressure sensor, or the like. Due to differences in the diameters and ranges of the different types of pressure sensors 180A. Therefore, the threshold values of the different pressure sensors 180A may be slightly different, but as a whole, as long as the pressure sensors can detect the pressure signal when the first casing 100A is pressed, the pressure sensors 180A can be used in the embodiment of the present application.

The aforementioned first housing 100A, second housing 100b and pressure sensor 180A may constitute a housing assembly. Of course, in the housing assembly, the first housing 100a is provided with the mounting hole 101 at a position close to the second housing 100b, or the second housing 100b is provided with the mounting hole 101 at a position close to the first housing 100 a; the pressure sensor 180A is disposed in the mounting hole 101. In the housing assembly provided in the embodiment of the present application, when the first housing 100A and the second housing 100b are close to each other along the reverse folding direction, the pressure sensor 180A may detect a pressure signal caused by the close of the first housing 100A and the second housing 100b, and the processor 110 determines, from the pressure signal, that the first housing 100A and the second housing 100b are folded along the reverse folding direction.

Based on the structure of the foldable electronic device 100 proposed above, the embodiment of the present application further discloses an anti-reverse intelligent alarm method. The anti-reverse-folding intelligent alarm method provided by the embodiment comprises the following steps: the pressure sensor detects a pressure signal; the processor 110 obtains pressure data from the pressure signal, and compares the pressure data with a first threshold value to obtain a comparison result; determining that the first shell 100a and the second shell 100b are reversely folded according to the reverse folding direction according to the comparison result; control the display screen 140 to display the reminder data, control the speaker to broadcast the reminder data, or control the micro-motor to perform alarm vibration.

The detailed operation of the pressure sensor and the processor 110 can be referred to the foregoing, and will not be described herein.

Example two

Referring to fig. 17 to 20 in conjunction with fig. 10, fig. 17 illustrates a rear perspective view of an inwardly turned foldable electronic device 100; fig. 18 is an enlarged schematic view of portion D of fig. 17.

The foldable electronic device 100 shown in the figure comprises a first casing 100a, a second casing 100B, a display screen 140 and a first strain gauge 180B, wherein the display screen 140 is disposed on the inner surface of the first casing 100a and the second casing 100B, and the first casing 100a and the second casing 100B can be folded around a folding axis O1O2 according to the folding direction; the first casing 100a is provided with a mounting groove 103 at a position close to the second casing 100B, and the first strain gauge 180B is attached to the bottom of the mounting groove 103.

In the process of folding the foldable electronic device 100 from the unfolded state to the folded state along the folding direction, as shown in fig. 19, the mounting groove 103 is gradually separated from the second housing 100b, and the mounting groove 103 is not pressed by the second housing 100 b; when the foldable electronic device 100 is turned from the unfolded state to the unfolded state in the reverse folding direction due to an erroneous operation of the electronic device 100, the portion of the second housing 100b opposite to the mounting groove 103 presses the mounting groove 103, and the bottom of the mounting groove 103 is deformed due to stress, as shown in fig. 20.

It should be noted that, in the drawings, the installation groove 103 is disposed on the first casing 100a for illustration, in some embodiments of the present application, the installation groove 103 may also be disposed on the second casing 100b, and the structure disposed on the second casing 100b is similar to the structure disposed on the first casing 100a, and is not repeated herein.

As can be seen from the above description, when the electronic device 100 is folded in the reverse folding direction due to an incorrect operation, the first casing 100a and the second casing 100b have a mutual pressing structure, and by collecting the stress deformation of the structure, it can be determined whether the foldable electronic device 100 is in the reverse folding state. Based on this, the first strain gauge 180B detects a pressure signal resulting from the presence of mutual pressing of the first casing 100a and the second casing 100B. The foldable electronic device 100 may determine whether the electronic device 100 is in the reverse-folded state based on the pressure signal detected by the first strain gauge 180B.

In some embodiments, the cable of the first strain gauge 180B is electrically connected to the processor 110, the first strain gauge 180B detects a pressure signal applied to the first housing 100a by the second housing 100B and transmits the pressure signal to the processor 110, the processor 110 obtains pressure data from the pressure signal, compares the pressure data with a second threshold, and when the pressure data is greater than the second threshold, it indicates that the foldable electronic device 100 is in a reverse-folded state, and the processor 110 controls the display screen 140 to display reminding data, controls the speaker to broadcast the reminding data, or controls the micro motor to perform alarm vibration.

The operation of the first strain gauge 180B is described in detail below with reference to fig. 19 to 20:

referring to fig. 19, in the process that the foldable electronic device 100 is folded in the folding direction, the second housing 100B is not in contact with the first housing 100a, the pressure signal detected by the first strain gauge 180B is processed by the processor 110 to obtain pressure data, and the pressure data is smaller than a second threshold value, which indicates that the foldable electronic device 100 is not in the reverse folding state, and the processor 110 does not control the display screen 140 to display the reminding data, control the speaker to broadcast the reminding data, or control the micro motor to execute alarm vibration according to the pressure signal.

Referring to fig. 20, in the process that the foldable electronic device 100 is folded to the reverse folding direction, the second housing 100B and the first housing are squeezed with each other, the first strain gauge 180B detects a pressure signal, and the pressure signal is processed by the processor 110 to obtain pressure data, where the pressure data is greater than a second threshold value, which indicates that the foldable electronic device 100 is in the reverse folding state, and the processor 110 controls the display screen 140 to display reminding data, controls the speaker to broadcast the reminding data, or controls the micro motor to execute alarm vibration according to the comparison result.

It should be noted that the second threshold may be adjusted according to the selected first strain gauge 180B, and the first strain gauge 180B may be a resistance-type strain gauge in this embodiment of the application. When the resistance strain gauge is attached to a measured object, the resistance strain gauge can expand and contract along with the strain of the measured object, so that the metal foil of the resistance strain gauge expands and contracts along with the strain, and the resistance of the metal changes along with the mechanical expansion or contraction. Therefore, by measuring the change in the resistance, a pressure signal applied to the object to be measured can be obtained. In addition, by selecting metals of different strain materials, the strain detection capability of the metal can be different, and the third threshold value can be different.

The aforementioned first housing 100a, second housing 100B and first strain gauge 180B may constitute a housing assembly. Of course, in the housing assembly, the first housing 100a is provided with a mounting groove 103 at a position close to the second housing 100b, or the second housing 100b is provided with a mounting groove 103 at a position close to the first housing 100 a; the first strain gauge 180B is disposed in the mounting groove 103. According to the housing assembly provided by the embodiment of the application, when the first housing 100a and the second housing 100B are close to each other along the reverse folding direction, the first strain gauge 180B may detect a pressure signal caused by the close of the first housing 100a and the second housing 100B, and the processor 110 may obtain pressure data from the pressure signal, and may determine that the first housing 100a and the second housing 100B are folded in the reverse folding direction by using a relationship between the pressure data and a second threshold value.

Based on the structure of the foldable electronic device 100 proposed above, the embodiment of the present application further discloses an anti-reverse intelligent alarm method. The anti-reverse-folding intelligent alarm method provided by the embodiment comprises the following steps: the first strain gauge 180B detects a pressure signal. The processor 110 processes the pressure signal into pressure data and compares the pressure data to a second threshold. When the processor 110 determines that the pressure data is greater than the second threshold, the display screen 140 is controlled to display the reminding data, the speaker is controlled to broadcast the reminding data, or the micro motor is controlled to execute alarm vibration.

The specific working processes of the first strain gauge 180B and the processor 110 can be referred to the foregoing, and are not described herein.

As can be seen from the above description, when the electronic device 100 is folded in the reverse folding direction due to an erroneous operation, the folded portion of the display screen 140 around the folding axis O1O2 is squeezed, and the stress deformation of the part of the structure is collected, so that it can be determined whether the foldable electronic device 100 is in the reverse folding state. Based on this, the second strain gauge 180C in the embodiment of the present application is attached to the folded portion of the display screen 140 around the folding axis O1O2 to detect the pressure signal at this portion. The foldable electronic device 100 may determine whether the electronic device 100 is in the reverse-folded state based on the pressure signal detected by the second strain gauge 180C.

Referring to fig. 24, in the process that the foldable electronic device 100 is folded from the unfolded state to the folded state according to the folding direction, the second strain gauge 180C detects a pressure signal of a folded portion of the display screen 140 around the folding axis O1O2 and outputs the pressure signal to the processor 110, the processor 110 obtains pressure data from the strain signal, and when the pressure data is greater than a third threshold value, it indicates that the foldable electronic device 100 is in the folded state, and the processor 110 controls the display screen 140 to display reminder data, controls the speaker to broadcast reminder data, or controls the micro motor to execute alarm vibration.
