[0047] The advantages of the present invention are further described below in conjunction with the drawings and specific embodiments.
[0048] Smart devices can be implemented in various forms. For example, the terminal described in the present invention may include mobile phones, smart phones, notebook computers, digital broadcast receivers, PDAs (personal digital assistants), PADs (tablets), PMPs (portable multimedia players), navigation devices, etc. Smart devices and fixed terminals such as digital TVs, integrated computers, etc. Below, assume that the terminal is a smart device. However, those skilled in the art will understand that, in addition to elements particularly used for mobile purposes, the configuration according to the embodiments of the present invention can also be applied to fixed-type terminals.
[0049] At present, multiple sensors are installed in smart devices, such as acceleration sensors, gyroscope sensors, temperature sensors, proximity sensors, etc., through which some states of the smart device can be obtained. In this embodiment, the acceleration sensor and the proximity sensor can determine whether the smart device is in an accidental falling state. When it is in an accidental falling state, it proves that the smart device is at risk of being damaged.
[0050] Refer to figure 1 , In accordance with the flow chart of the anti-fall method for smart devices in a preferred embodiment of the present invention, the method includes:
[0051] Step 101: Install an anti-fall device on the smart device, and the anti-fall device includes a buffer part;
[0052] An anti-fall device is installed on a smart device. The embodiment of the present invention has no special regulations on the location of the smart device. However, since the present invention provides an anti-fall method for the smart device, preferably, The drop device is installed on the rear or upper part of the smart device, and at the same time, it must be able to disassemble and assemble the anti-drop device relatively easily, because the anti-drop device cannot affect the operation of the smart device. To ensure its normal operation, If the installation location is not random, the anti-drop device will cause great inconvenience to the user when the smart device is used normally.
[0053] Step 102: Detect the acceleration of the smart device;
[0054] In an embodiment of the present invention, the user can configure the anti-fall device, and most importantly, configure the anti-fall mode. In this embodiment, there are three modes for the user to choose from, unprotected mode, ground mode, and surface mode. After configuring the anti-drop mode, the anti-drop device can perform different anti-drop measures on the smart device according to different anti-drop modes.
[0055] Step 103: When the acceleration of the smart device is equal to or greater than an acceleration threshold, the anti-fall device activates the buffering part to wrap the smart device and buffer the impact force received by the smart device;
[0056] Since the acceleration sensor can measure the current acceleration force of the smart device, the acceleration of the smart device during the acceleration process can be obtained through the acceleration sensor. When the smart device is in an accidental falling state, the value of the acceleration of the smart device is often greater than or equal to a preset threshold. In an embodiment of the present invention, the preset threshold may be the acceleration of gravity. When the smart device is under gravity only, the smart device will make a free landing motion when the smart device falls unexpectedly, and the acceleration value obtained by the acceleration sensor of the smart device should be the acceleration of gravity. When the smart device has gravity and external force applied by the user, and the smart device falls unexpectedly, the acceleration value obtained by the acceleration sensor of the smart device at this time will be greater than the acceleration of gravity, and it will return a preset value such as 0, when the returned value is 0, it means that the smart device is in an unprotected state, that is, it can be determined that the smart device is in an accidental falling state.
[0057] In this embodiment, once it is detected that the smart device is in an accidentally falling state, the anti-fall measures for the smart device are triggered.
[0058] When the smart device’s anti-drop mode is the ground mode, a parachute bag will be opened on the smart device when it falls vertically. The parachute includes a fixed shell assembled on the upper part of the smart device’s main body. The umbrella body in the fixed shell is made of airtight fabric.
[0059] At the same time, through the elastic gravity block, the overall center of gravity of the smart device is in the lower part of the smart device, so that when the smart device falls, the smart device falls vertically due to the action of the counterweight. When the falling speed of the smart device is not fast, the bottom of the elastic gravity block hits the ground. Due to the elasticity of the rubber, the main body of the smart device is cushioned to a certain extent and is not easily broken; when the smart device falls, the height is higher and the falling speed When it is faster, the parachute is exposed to the wind, the umbrella body inside is blown open, and the same smart device is pulled up, thereby buffering and decelerating the smart device, so that the main body of the smart device will slowly land without being damaged. In this case, the parachute bag will not open when the smart device is dropped randomly, so that the user needs to fold the parachute bag frequently.
[0060] When the anti-drop mode of the smart device is the surface mode, in order to achieve the purpose of the present invention, an anti-drop measure of a floatable airbag is opened. The airbag is provided with an inflatable inflatable cavity, which uses a principle similar to a balloon to complete the inflation. The airbag can make the entire smart device float on the water, which can free the user's hands and make it possible to perform their own operations. It is convenient for the user and can effectively prevent the protective cover from being lost due to sinking underwater. phenomenon.
[0061] At the same time, the inflated width of the airbag can also be set to be greater than the width of the smart device, so that the two ends of the smart device can be balanced, and it can also prevent the smart device from turning over, so that the smart device can float on the water in a balanced manner. on. The inflation port of the inflation cavity uses the inflation port similar to the principle of a water pump. The airbag can also be designed into various shapes according to needs, and after inflation, it can be formed into various shapes like a balloon to enhance the aesthetics of the protection device.
[0062] In one embodiment of the present invention, the power-off data protection function can be activated at the same time. When the smart device is detected to be accidentally dropped, the smart device is shut down and stored in the internal components before the power supply to the internal components is cut off by turning off the power of the smart device Current data, close internal components.
[0063] Refer to figure 2 , In order to comply with the anti-fall device 10 of the smart device of the present invention, it can be implemented by an anti-fall device. The anti-fall device includes: 20-detection module, 30-control module, 40-protection module, 50-buffer module
[0064] Detection module 20:
[0065] Since the acceleration sensor can measure the current acceleration force of the smart device, the acceleration of the smart device during the acceleration process can be obtained through the acceleration sensor. When the smart device is in an accidental falling state, the value of the acceleration of the smart device is often greater than or equal to a preset threshold. In an embodiment of the present invention, the preset threshold may be the acceleration of gravity. When the smart device is under gravity only, the smart device will make a free landing motion when the smart device falls unexpectedly, and the acceleration value obtained by the acceleration sensor of the smart device should be the acceleration of gravity. When the smart device has gravity and an external force applied by the user, and the smart device falls unexpectedly, the acceleration value acquired by the acceleration sensor of the smart device at this time will be greater than the acceleration of gravity.
[0066] Specifically, when the user is carrying the smart device in the process of accelerating motion, and the current acceleration has exceeded the preset acceleration threshold, and in this case, the smart device is not in an accidental falling state. Therefore, in order to prevent misjudgment When the acceleration exceeds the acceleration threshold, the phenomenon occurs by judging whether the smart device is currently in an unprotected state through the proximity sensor. When the distance between the proximity sensor in the smart device and the object does not exceed its preset coverage, it will return to a preset first value, when the distance between the proximity sensor in the smart device and the object exceeds When its preset coverage area, it will return to a preset second value. In this embodiment, the object may be the user or other items. For example, when the smart device is placed in the user's bag, the object may be the user's bag. For example, when the proximity sensor can sense an obstruction within 5 cm from it, and when the object is within 5 cm, the proximity sensor can return a preset value such as 5, indicating that the smart device is in a protected state. When the object is not within 5cm, the proximity sensor cannot detect the object and will return a preset value such as 0. When the returned value is 0, the smart device is in an unprotected state, that is, it can be determined that the smart device is Accidental falling state.
[0067] Control module 30:
[0068] The control module 30 can configure the anti-drop protection state of the smart device. In one embodiment of the present invention, the accidental fall of the smart device causes the greatest damage to accidentally falling into the water or falling on the ground from a height. Therefore, this embodiment In an example, three anti-falling measures can be set for the smart device through the control module 30, including an unprotected mode, a ground mode and a water surface mode. According to the environment in which the smart device is located, setting different protection modes can protect the smart device more safely.
[0069] In this embodiment, the control module 30 always monitors the determination result of the detection module 20. Once the control module 30 detects that the detection module 20 determines that the smart device is accidentally dropped, that is, the detection module 20 returns to the control module 30 that the smart device is The judgment value of the accidental falling state is 0 in this embodiment, and the detection module 20 triggers the protection module 40 to start the anti-fall measures for the smart device.
[0070] Protection module 40:
[0071] The buffer module 50 of the protection module 40 is equipped with anti-fall measures for the smart device. In this embodiment, the control module 30 can set three anti-fall measures for the smart device: no protection mode, ground mode, and water surface mode. The protection module 40 It is also equipped with corresponding anti-drop measures.
[0072] For the case where the anti-drop mode of the smart device is the ground mode, in this embodiment, the protection module 40 provides an anti-drop measure that the smart device will open a parachute bag when the smart device falls vertically during a fall. The parachute includes an assembly mounted on the main body of the smart device. The upper fixed shell is the umbrella body that is plugged into the fixed shell, and the umbrella body is made of airtight fabric.
[0073] In this anti-fall measure, an elastic gravity block is installed at the lower part of the smart device, so that the overall center of gravity of the smart device is in the lower part of the smart device, so that when the smart device falls, the smart device falls vertically due to the action of the counterweight. When the falling speed of the smart device is not fast, the bottom of the elastic gravity block hits the ground. Due to the elasticity of the rubber, the main body of the smart device is cushioned to a certain extent and is not easily broken; when the smart device falls, the height is higher and the falling speed When it is faster, the parachute is exposed to the wind, the umbrella body inside is blown open, and the same smart device is pulled up, thereby buffering and decelerating the smart device, so that the main body of the smart device will slowly land without being damaged. In this case, the parachute bag will not open when the smart device is dropped randomly, so that the user needs to fold the parachute bag frequently.
[0074] When the anti-drop mode of the smart device is the surface mode, in order to achieve the purpose of the present invention, the protection module 40 provides anti-drop measures for a floatable airbag. The airbag is provided with an inflatable inflatable cavity, using a principle similar to a balloon, The inflated airbag can make the entire smart device float on the water surface, which can free the user's hands and enable him to perform his own work. It is convenient for the user and can also effectively prevent the protective cover from sinking underwater. And the phenomenon of loss.
[0075] At the same time, the inflated width of the airbag can also be set to be greater than the width of the smart device, so that the two ends of the smart device can be balanced, and it can also prevent the smart device from turning over, so that the smart device can float on the water in a balanced manner. on. The inflation port of the inflation cavity uses the inflation port similar to the principle of a water pump. The airbag can also be designed into various shapes according to needs, and after inflation, it can be formed into various shapes like a balloon to enhance the aesthetics of the protection device.
[0076] In an embodiment of the present invention, the protection module 40 also includes a power-off data protection function. When the control module 30 detects that the detection module 20 determines that the smart device is accidentally dropped, the power supply to the internal components is cut off by turning off the power of the smart device. Previously, the smart device was turned off and the current data in the internal component was stored, and the internal component was turned off.
[0077] In addition, an embodiment of the present invention also provides a computer-readable storage medium in which computer-executable instructions are stored. The above-mentioned computer-readable storage medium is, for example, a non-volatile memory such as an optical disk, a hard disk, or a flash memory. The above-mentioned computer executable instructions are used to allow a computer or similar computing device to complete various operations in the above-mentioned anti-fall method for smart devices.
