Fig. 2 is a schematic structural diagram illustrating a foldable device according to an exemplary embodiment, fig. 3 is a schematic structural diagram illustrating a hinge according to an exemplary embodiment, the foldable device may be a mobile phone, a tablet computer, or the like, and referring to fig. 2, the foldable device includes: a first housing 201, a second housing 202, a rotating shaft 203 and a processing unit 204.
Referring to fig. 3, the rotating shaft 203 includes a first sliding block 2031, a second sliding block 2032, and a sliding rail 2033, and the first sliding block 2031 and the second sliding block 2032 are located on the sliding rail 2033 and can slide along the sliding rail 2033. The first sliding block 2031 is fixedly connected to the first casing 201, and the second sliding block 2032 is fixedly connected to the second casing 202.
The processing unit 204 is located in an inner space formed by the first casing 201 and the second casing 202, and is connected to the rotating shaft 203. The processing unit 204 is configured to control the rotation shaft 203 to rotate, so as to drive the first housing 201 or the second housing 202 to rotate around the rotation shaft 203, and the first slider 2031 and the second slider 2032 slide on the sliding rail 2033, thereby implementing folding or unfolding of the foldable device.
In one possible implementation, the rotating shaft 203 includes a rotating part, and the first slider 2031 and the second slider 2032 and the processing unit 204 are connected to the rotating part. When the processing unit 204 controls the rotation of the rotation part, the first slider 2031 and the second slider 2032 are slid on the sliding rail 2033. When the first slider 2031 and the second slider 2032 slide, the first housing 201 and the second housing 202 are rotated about the rotation shaft 203.
For example, the first slider 2031, the second slider 2032, and the slide rail 2033 are located at one end of the rotating shaft 203 and are connected to the rotating part. The first sliding block 2031 is fixedly connected with the first casing 201 through a first connecting rod, and drives the first casing 201 through the first connecting rod, and the second sliding block 2032 is fixedly connected with the second casing 202 through a second connecting rod, and drives the second casing 202 through the second connecting rod.
In another possible implementation manner, the rotating shaft 203 includes a rotating part, the first housing 201 and the second housing 202 are connected to the rotating part, and the first slider 2031 and the second slider 2032 are not connected to the rotating part. When the processing unit 204 controls the rotation part to rotate, the first housing 201 and the second housing 202 are driven to rotate around the rotation shaft 203. When the first housing 201 and the second housing 202 rotate around the rotating shaft 203, the first slider 2031 and the second slider 2032 are driven to slide on the sliding rail 203.
For example, the first slider 2031, the second slider 2032, and the slide rail 2033 are located at one end of the rotating portion, and the rotating portion is fixedly connected to the first housing 201 through the first fixing member, and the first housing 201 is driven by the first fixing member. The rotating portion is fixedly connected to the second housing 202 through a second fixing member, and the second housing 202 is driven by the second fixing member.
Referring to the circular marks on fig. 4, a plurality of detecting devices for transmitting a position indication signal to the processing unit 204 when the first slider 2031 or the second slider 2032 is detected are fixedly disposed on the slide rail 2033. The processing unit 204 is configured to obtain a distance between the first slider 2031 and the second slider 2032 according to the received position indication signal, and determine a folding angle of the foldable device according to the distance between the first slider 2031 and the second slider 2032.
Referring to fig. 5, 6 and 7, the folding angle of the foldable device is an angle formed by the first housing 201 and the second housing 202 with the rotation shaft 203 as a tip, and is not less than 0 degree and not more than 180 degrees. The state of the foldable device can be determined according to the folding angle. When the foldable device is in the unfolded state, the folding angle of the foldable device is 180 degrees; when the foldable equipment is in a folded state, the folding angle of the foldable equipment is 0 degree; when the foldable device is in an intermediate state between the unfolded state and the folded state, the folding angle of the foldable device is some angle between 0 degrees and 180 degrees.
The detecting devices are fixedly disposed on the sliding rail 2033, each detecting device is located at a position of the sliding rail 2033, and when any detecting device detects a slider, the position of the detecting device can be regarded as the position of the slider.
In a possible implementation manner, the plurality of detecting devices may be distributed on one side of the sliding rail 2033, or the plurality of detecting devices may be distributed on both sides of the sliding rail 2033. The plurality of detection devices may be uniformly distributed on the sliding rail 2033, or may be randomly distributed on the sliding rail 2033. For example, a total of 6 detection devices are disposed on the sliding rail 2033, 3 detection devices are disposed on each side of the sliding rail 2033, each detection device has a vertical line perpendicular to the sliding rail 2033, and the distance between any two adjacent vertical lines in the 6 detection devices is equal.
The position indication signal is a signal sent by the detection device to the processing unit 204, and is used to indicate that the detection device detects the slider at the current time. The position indication signal carries identification information of the detection device which sends the position indication signal. After receiving the position indication information, the processing unit 204 determines the position of the corresponding detection device according to the identification information in the position indication information, and determines the position of the detection device as the position of the slider.
It should be noted that the rotating shaft 203 includes a rotating portion, slide rails 203 may be disposed on one end or both ends of the rotating portion, a first slider 2031 and a second slider 2032 are disposed on each slide rail 203, and the first slider 2031 and the second slider 2032 are respectively connected to the first housing 201 and the second housing 202. Wherein, set up slide rail 2033 at the both ends of rotating part, can follow both ends fixed rotating shaft 203, first casing 201 and second casing 202, improved the stability of collapsible equipment.
Each slide rail 2033 may be provided with a plurality of detection devices, or because two slide rails 2033 are symmetrical structures, the measured slide positions should be the same, so in order to save cost, a plurality of detection devices may be provided on only one of the slide rails 2033, and no longer provided on the other slide rail 2033.
The detection device may be a magnetic sensor, a light sensor, a distance sensor or other detection device.
In one possible implementation, the detecting device is a magnetic sensor, such as a hall sensor or other type of sensor, and the plurality of detecting devices includes a plurality of magnetic sensors, which are distributed at different positions on the sliding rail 2033, and each of the magnetic sensors is used for emitting a magnetic field signal. Each of the first slider 2031 and the second slider 2032 is provided with a magnetic substance that causes a magnetic field signal to fluctuate.
For each magnetic sensor, when the magnetic substance is closer to the magnetic sensor, the magnetic field signal emitted from the magnetic sensor is influenced more, resulting in a larger fluctuation amplitude of the magnetic field signal. In the process of the magnetic substance from far to near and then from near to far, the fluctuation amplitude of the magnetic field signal is changed from small to large and then from large to small. Therefore, from the fluctuation amplitude of the magnetic field signal of the magnetic sensor, the relative positional relationship between the magnetic substance and the magnetic sensor can be determined.
When the fluctuation amplitude of the magnetic field signal sent by the magnetic sensor exceeds the first preset threshold, it is considered that a slider exists near the magnetic sensor, and at this time, the position of the magnetic sensor can be taken as the position of the slider, so that the magnetic sensor sends a position indication signal to the processing unit 204, where the position indication signal carries identification information of the magnetic sensor, and indicates that the magnetic sensor corresponding to the identification information detects a slider.
The processing unit 204 determines the position of the magnetic sensor as the position of one of the sliders based on the identification information of the magnetic sensor. By using at least two magnetic sensors, the positions of the two sliders, i.e., the first slider 2031 and the second slider 2032, can be determined. Then, the processing unit 204 can obtain the distance between the first slider 2031 and the second slider 2032, and determine the folding angle of the foldable device according to the distance.
In another possible implementation manner, the detecting devices are optical sensors, the detecting devices include multiple sets of optical sensors, the multiple sets of optical sensors are distributed at different positions of the sliding rail 2033, each set of optical sensors includes an optical emitter and an optical receiver fixed on two sides of the sliding rail 2033, and the optical emitter and the optical receiver of each set of optical sensors are disposed opposite to each other.
Wherein each optical transmitter is used for transmitting optical signals to a corresponding optical receiver, and each optical receiver is used for receiving the optical signals transmitted by the corresponding optical transmitter. When there is no object block between one group of optical transmitters and optical receivers, the optical receivers can receive the optical signals transmitted by the corresponding optical transmitters. When a light receiver does not receive the light signal at a certain time, it indicates that the first slider 2031 or the second slider 2032 is located between the light receiver and the corresponding light emitter, and at this time, the light receiver sends a position indication signal to the processing unit 204, where the position indication signal carries identification information of the light sensor, and indicates that the light sensor corresponding to the identification information detects the first slider 2031 or the second slider 2032.
The optical signal sent by the optical transmitter may be an infrared signal or an optical signal in other frequency bands.
In another possible implementation manner, the detecting device is a distance sensor, and the plurality of detecting devices includes a plurality of distance sensors, and the plurality of distance sensors are distributed at different positions of the sliding rail 2033. The distance sensor is used for transmitting a detection signal, receiving a reflection signal obtained by reflecting the detection signal by a measured object, and determining the distance between the distance sensor and the measured object according to the detection signal and the reflection signal.
The detection signal and the reflection signal may be optical signals or ultrasonic signals.
For each distance sensor, in the process of the first slider 2031 or the second slider 2032 moving from far to near and then from near to far, the distance from the distance sensor also decreases and then increases, and when the distance from the first slider 2031 or the second slider 2032 to the distance sensor is the minimum, it indicates that the first slider 2031 or the second slider 2032 is located near the distance sensor at this time.
When a distance sensor detects that the distance between the first slider 2031 or the second slider 2032 is smaller than a second preset threshold, the first slider 2031 or the second slider 2032 is considered to be located near the distance sensor, and at this time, the distance sensor sends a position indication signal to the processing unit 204, where the position indication signal carries identification information of the distance sensor, and indicates that the distance sensor corresponding to the identification information detects the first slider 2031 or the second slider 2032.
In one possible implementation, the foldable device further comprises a flexible display screen 205. The flexible display screen 205 is located on the same side surface of the first casing 201, the second casing 202 and the rotation shaft 203, and deforms with the rotation of the first casing 201 or the second casing 202.
The flexible display screen 205 is made of a flexible material, and may be made of glass, acrylic, transparent plastic composite, PMMA (polymethyl methacrylate), PC (Polycarbonate), or the like, which is a flexible and deformable display material.
The first casing 201 or the second casing 202 may rotate about the rotation shaft 203 such that the flexible display screen 205 located at the same side surface of the first casing 201, the second casing 202, and the rotation shaft 203 is unfolded or folded as the first casing 201 or the second casing 202. Also, by rotating the first casing 201 or the second casing 202 about the rotation shaft 203, the state of the foldable device can be switched, such as switching the foldable device from the folded state to the unfolded state or switching from the unfolded state to the folded state.
In a first possible implementation manner, when the foldable device is in the unfolded state, the first housing 201 and the second housing 202 are rotated around the rotation shaft 203, so that the flexible display screen 205 is bent until the two parts of the flexible display screen 205 are in close contact, and the foldable device is in the folded state.
In a second possible implementation manner, when the foldable device is in the folded state, the first casing 201 and the second casing 202 are rotated around the rotating shaft 203, so that the flexible display screen 205 is gradually unfolded until the flexible display screen 205 is completely unfolded into a plane, and the first casing 201, the second casing 202 and the rotating shaft 203 are in the same plane, at which time the foldable device is in the unfolded state.
The processing unit 204 may be connected to the flexible display screen 205, and control the flexible display screen 205 to display. For example, after the processing unit 204 determines the folding angle during the folding or unfolding process of the foldable device, the folding angle may be displayed on the flexible display screen 205 so that the user can know the folding angle in time. Alternatively, the processing unit 204 may provide the user with the fold angle in other ways, such as playing audio information including the fold angle through a speaker configured with the foldable device.
In the related art, a foldable device is configured with a first housing, a second housing, and a rotating shaft, wherein the first housing and the second housing are both movably connected to the rotating shaft and can rotate around the rotating shaft. The user can determine the folding angle of the foldable device by observation and determine whether to maintain the current state of the foldable device or to switch the state of the foldable device according to the folding angle, and use the foldable device after switching to another state. Since the folding angle of the foldable device can only be determined by the user through observation, the determined folding angle is not accurate enough, and when the subsequent user uses the foldable device based on the folding angle, the device is easily damaged.
