First embodiment
Referring to fig. 1 and fig. 2, the present embodiment provides a mobile terminal device 1, where the mobile terminal device 1 includes a main body 10, a display 20, a protection device 30, a first sensor 40, and a processor 50. The display screen 20 and the protection device 30 are disposed on the same side of the main body 10.
Referring to fig. 2, the first sensor 40 and the processor 50 are disposed inside the main body 10 of the mobile terminal 1, for example, may be disposed on the PCB 12 of the mobile terminal 1, and the processor 50 is electrically connected to the first sensor 40.
The first sensor 40 may be a gravity sensor or an acceleration sensor, and is configured to obtain an acceleration value of the mobile terminal device 1. Taking the first sensor 40 as a gravity sensor as an example, the first sensor 40 may acquire an acceleration value of the mobile terminal device 1 in the vertical direction, and at the same time, the first sensor 40 sends the acquired acceleration value to the processor 50.
The processor 50 is an integrated circuit chip having signal processing capabilities. For example, the Processor may be a general-purpose Processor, including a Central Processing Unit (CPU), a Network Processor (NP), and the like; but also as Digital Signal Processors (DSPs), Application Specific Integrated Circuits (ASICs), array of ready-made programmable gates (FPGAs) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, which may implement or perform the methods, steps disclosed in embodiments of the present invention. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
The processor 50 is configured to receive the acceleration value sent by the first sensor 40, and send a first control signal to the protection device 30 when the processor 50 detects that the received acceleration value meets a preset condition. Specifically, the preset condition may be that the acceleration value is greater than or equal to the preset acceleration value. That is, the processor 50 receives the acceleration value sent by the first sensor 40, compares the acceleration value with a preset acceleration value, and if the acceleration value is greater than or equal to the preset acceleration value, determines that a preset condition is met, and sends a first control signal to the protection device 30. The preset acceleration value may be preset by a manufacturer that produces the mobile terminal device 1, or may be preset by a user of the mobile terminal device 1.
The specific structure of the protection device 30 will be described with reference to the accompanying drawings.
referring to fig. 1 and 2 again, a portion of the main body 10 facing the display screen 20 is provided with a through hole 11. The protection device 30 is disposed in the main body 10 of the mobile terminal apparatus 1, and includes a stopper 31 and an ejector 32. The limiting member 31 is electrically connected to the processor 50, and the ejecting member 32 is disposed corresponding to the through hole 11.
The protection device 30 has a first relative position and a second relative position with respect to the main body 10.
When the protection device 30 is located at the first relative position, the ejecting member 32 is subjected to a limiting effect of the limiting member 31, and is flush or substantially flush with the display screen 20, or is recessed toward the inside of the main body 10 relative to the display screen 20, and when the limiting member 31 receives the first control signal, the limiting member 31 ejects the ejecting member 32 from the through hole 11, so that the ejecting member 32 protrudes from the display screen 20.
Further, the ejector 32 includes an elastic connector 321 and a movable portion 322, and the movable portion 322 is connected to the inside of the main body 10, for example, the PCB 12, through the elastic connector 321.
As an embodiment, the elastic connection member 321 may be a return spring, which can be elastically deformed under the action of an external force, and can be restored to the original state and be in a free state after the external force is removed. In this embodiment, when the limiting member 31 is in the limiting state, the elastic connecting member 321 is in a state of being compressed by the movable portion 322, and when the limiting member 31 is in the non-limiting state, the elastic connecting member 321 is in a free state.
The movable portion 322 includes a first movable portion 3221, a second movable portion 3222, and a third movable portion 3223, and in one aspect, the first movable portion 3221, the second movable portion 3222, and the third movable portion 3223 are integrally formed, and the whole shape of the movable portion is a rectangular wave. The first movable portion 3221 is connected to the inside of the main body 10 through the elastic connection member 321, and the third movable portion 3223 is also connected to the inside of the main body 10 through the elastic connection member 321.
in this embodiment, when the protection device 30 is in the first relative position, the second movable portion 3222 is flush with the display screen 20 or is recessed inward of the main body 10 relative to the display screen 20. When the protection device 30 is at the second relative position, the second movable portion 3222 protrudes from the display screen 20.
as an embodiment, the second movable portion 3222 may be made of a high-strength and impact-resistant metal material.
referring to fig. 3 and fig. 4, the limiting member 31 includes a first limiting member 311 and a second limiting member 312, and the first limiting member 311 and the second limiting member 312 are disposed at two sides of the movable portion 322 relatively. The first limiting member 311 is used to limit the movable portion 322 to be close to the first movable portion 3221 of the first limiting member 311, and the second limiting member 312 is used to limit the movable portion 322 to be close to the third movable portion 3223 of the second limiting member 312.
There are various embodiments of the first limiting member 311, and in this embodiment, as one embodiment, the first limiting member 311 may include a first stepping motor 3111 and a first limiting plate 3114. The first stepper motor 3111 may include a first shaft 3112 and a first motor body 3113. The first motor body 3113 is rotatably connected to the PCB board 12 of the body 10 through a first shaft 3112. The first stopper plate 3114 is provided on the first motor body 3113, and extends in a direction perpendicular to the first rotation axis 3112 from the first motor body 3113 to a direction away from the first rotation axis 3112. Further, the distance between the bottom of the first stopper plate 3114 and the PCB 12 is greater than the distance between the top of the first movable portion 3221 and the PCB 12 when the elastic connector 321 is in a compressed state. When the first stepping motor 3111 rotates, the first limiting plate 3114 can be driven to rotate to a position where the first moving portion 3221 is in contact with, so that the first moving portion 3221 is limited.
Similarly, the second limiting member 312 may be a second stepping motor 3121 and a second limiting plate 3124. The second stepping motor 3121 may include a second rotating shaft 3122 and a second motor main body 3123. The second stepping motor 3121 is rotatably connected to the PCB panel 12 of the main body 10 by a second rotating shaft 3122. A second limit plate 3124 is provided on the second motor main body 3123 to extend from the second motor main body 3123 in a direction perpendicular to the second rotation shaft 3122 in a direction away from the second rotation shaft 3122. Further, the distance from the bottom of the second limiting plate 3124 to the PCB 12 is greater than the distance from the top of the third movable portion 3223 to the PCB 12 when the elastic connection 321 is in a compressed state. When the second stepping motor 3121 rotates, the second limiting plate 3124 may be driven to rotate to a position contacting with the third movable portion 3223, so as to limit the third movable portion 3223.
In this embodiment, the first stepping motor 3111 and the second stepping motor 3121 may be rotated under the control of the processor 50 to separate the first stopper plate 3114 from the first movable portion 3221 to release the stopper function of the first movable portion 3221, and separate the second stopper plate 3124 from the third movable portion 3223 to release the stopper function of the third movable portion 3223.
since the mobile terminal apparatus 1 is mostly in free-fall motion or in flat-throw motion during falling out of the user's control, the acceleration of the mobile terminal apparatus 1 in the vertical direction is greater than or equal to the acceleration of gravity G (typically 9.8m/s 2). Thus, as an implementation paradigm, the preset acceleration value may be set to 9.8m/s 2.
Further, when the processor 50 detects that the acceleration of the mobile terminal apparatus 1 in the vertical direction is greater than or equal to the acceleration of gravity of 9.8m/s2, it is determined that the mobile terminal apparatus 1 is in the falling state, and the processor 50 controls the protection device 30 to move from the first relative position to the second relative position. Since the protection device 30 protrudes relative to the display 20 when in the second relative position, the protection device can protect the display 20 of the mobile terminal device 1 and prevent the display 20 from being accidentally damaged.
Further, please refer to fig. 5 and fig. 6, in combination with the protection device 30, the first sensor 40 and the processor 50, when the processor 50 receives that the acceleration value sent by the first sensor 40 is greater than or equal to the preset acceleration value, it indicates that the mobile terminal device 1 is in the falling state. The processor 50 transmits first control signals to the first stepping motor 3111 and the second stepping motor 3121, respectively. After receiving the first control signal, the first stepping motor 3111 may rotate clockwise or counterclockwise (for example, the rotation direction of the first stepping motor 3111 is counterclockwise as indicated by an arrow in fig. 5) by a first preset angle, so that the first stopper plate 3114 rotates from facing the first movable portion 3221 to departing from the first movable portion 3221, and is separated from the first movable portion 3221. After receiving the first control signal, the second stepping motor 3121 may rotate by a first preset angle in a direction opposite to the rotation direction of the first stepping motor 3111, so that the second limiting plate 3124 rotates from facing the third movable portion 3223 to departing from the third movable portion 3223, thereby separating from the third movable portion 3223. The elastic connecting element 321 is released from the compression deformation and returns to the free state, so that the movable portion 322 moves from the first relative position to the second relative position, and the second movable portion 3222 protrudes from the main body 10, i.e., the display screen 20, in the direction shown by the arrow in fig. 6. Therefore, the impact force almost entirely falls on the second movable portion 3222, and the destructive force to the display screen 20 is greatly reduced, so that the display screen 20 is effectively protected and the display screen 20 is prevented from being accidentally broken.
Wherein the first preset angle may be 180 degrees.
in order to make the protection device 30 at the first relative position not affect the overall aesthetic appearance of the mobile terminal device 1, and at the same time, in order to avoid adding components on the original basis of the mobile terminal device 1 as much as possible, as an embodiment, the movable portion 322 may be a speaker net located on a receiver of the main body 10, or may be a decorative ring sleeved on a key of the display 20, where the key is located on one side of the display 20.
In addition, please refer to fig. 7, in order to equalize the stress of the protection device 30 when the mobile terminal device 1 falls to the ground, so that the protection device 30 can better protect the display screen 20, as an implementation paradigm, two protection devices 30 may be simultaneously disposed on the mobile terminal device 1, and the movable portions 322 of the two protection devices 30 are respectively a decorative ring of keys on the display screen 20 and a speaker net on the earpiece of the main body 10.
further, the protection device 30 may protrude 0.5mm compared to the display screen 20 when in the second relative position. After the mobile terminal device 1 falls to the ground, because the speaker net and the decorative ring are popped up and are higher than the display screen 20 by 0.5mm, impact stress points almost fall on the two parts, the destructive power to the display screen 20 is greatly reduced, and the function of effectively protecting the display screen 20 is achieved.
It should be noted that the above-mentioned key may be a home key, a fingerprint unlocking key, or a key integrating a home key and a fingerprint unlocking key. Of course, all the keys described above may be physical keys or virtual keys.
In addition, the mobile terminal device 1 may be a smart phone, and may also be a tablet computer.
When the protective device 30 is in the second relative position, the speaker mesh and/or the bezel are raised relative to the display screen 20. At this time, if the protection device 30 cannot be restored to the first relative position, that is, the speaker net and/or the bezel cannot be restored to the original state, the aesthetic appearance of the mobile terminal apparatus 1 may be degraded.
Therefore, referring to fig. 8, as an embodiment, the mobile terminal device 1 may further include a second sensor 60.
The second sensor 60 is disposed in the main body 10 and electrically connected to the processor 50 for acquiring the moving state of the eject member 32.
Further, the second sensor 60 may be a distance sensor, and the moving state is a distance moved when the ejector 32 is shifted from the second relative position to the first relative position, and accordingly, the second sensor 60 may be configured to acquire a distance value between the first movable portion 3221 or the third movable portion 3223 and itself, and send the acquired distance value to the processor 50.
A distance sensor is a sensor that measures distance by emitting light pulses. Referring to fig. 9, a second sensor (distance sensor) 60 in the present embodiment includes an LED lamp 61 and a receiver 62. After the LED lamp 61 emits a beam of infrared light, the infrared light is reflected by the reflector 63 and attenuated. Eventually, the reflected light is received by the receiver 62. The receiver 62 can calculate the distance between the second sensor 60 and the reflector 63 from the received infrared reception value. In this embodiment, the reflector 63 may be the first movable portion 3221 or the third movable portion 3223, or may be a reflection plate additionally added to reflect infrared light.
The processor 50 is further configured to obtain the moving state acquired by the second sensor 60, and when it is detected that the moving state meets the limiting condition of the limiting member 31, the processor 50 sends a second control signal to the limiting member 31, so that the ejecting member 32 is switched from the second relative position to the first relative position. That is, the processor 50 receives the distance value sent by the second sensor 60 and compares the distance value with a preset distance value. The preset distance value represents a critical value at which the limiting member 31 can limit the ejecting member 32. If the distance value is smaller than the predetermined distance value, the processor 50 controls the eject member 32 to switch from the second relative position to the first relative position.
further, please refer to fig. 10 and 11, in combination with the protection device 30, the second sensor 60 and the processor 50, when the processor 50 receives that the distance value sent by the second sensor 60 is smaller than the preset distance value, the characteristic limiting member 31 may limit the ejecting member 32. The processor 50 transmits a second control signal to the first stepping motor 3111 and the second stepping motor 3121, respectively. After receiving the second control signal, the first stepping motor 3111 may rotate by a second preset angle (the rotation direction of the first stepping motor 3111 is clockwise as indicated by an arrow in fig. 10), so that the first limiting plate 3114 rotates from away from the first movable portion 3221 to toward the first movable portion 3221, and thus, the first stepping motor 3111 is squeezed by the first movable portion 3221. After receiving the second control signal, the second stepping motor 3121 may rotate by a second preset angle in a direction opposite to the rotation direction of the first stepping motor 3111, so that the second limiting plate 3124 rotates from departing from the third movable portion 3223 to facing the third movable portion 3223, thereby achieving squeezing with the third movable portion 3223. The elastic connecting element 321 is compressed and deformed to move the movable portion 322 from the second relative position to the first relative position according to the direction shown by the arrow in fig. 11, and the second movable portion 3222 is flush with the display screen 20 or recessed towards the inside of the main body 10 relative to the display screen 20 to move the protection device 30 from the second relative position to the first relative position, so that the mobile terminal device 1 can be finally restored to the normal state.
it is worth pointing out that the user can change the distance value between the first moving portion 3221 or the third moving portion 3223 and the second sensor 60 by pressing the microphone net or/and the decorative ring with the fingers, and can also change the distance value between the first moving portion 3221 or the third moving portion 3223 and the second sensor 60 by indirectly pressing the microphone net or/and the decorative ring with other objects.
as an implementation paradigm, the second rotation angle may be the same as the first rotation angle, and the rotation direction is opposite. In another embodiment, the rotation direction of the second rotation angle may be the same as the rotation direction of the first rotation angle, and in this case, the first rotation angle and the second rotation angle are both 180 degrees.
The working principle of the mobile terminal device 1 provided by the first embodiment of the present invention is as follows: the first sensor 40 acquires an acceleration value of the mobile terminal device 1, sends the acquired acceleration value to the processor 50, and when the processor 50 receives that the acceleration value sent by the first sensor 40 is greater than or equal to a preset acceleration value, the processor 50 represents that the mobile terminal device 1 is in a falling state, and the processor 50 controls the protection device 30 to be switched from a first relative position to a second relative position to protrude from the display screen 20. Therefore, the impact force almost entirely falls on the protection device 30, and the destructive force to the display screen 20 is greatly reduced, thereby effectively protecting the display screen 20. In addition, the user can press the hearing tube net or/and the decorative ring by fingers, and the like, so that the protection device 30 can be moved from the second relative position to the first relative position again, that is, the mobile terminal device 1 can be restored to a normal state, and the beauty of the mobile terminal device 1 is ensured.
Second embodiment
