Description of the Invention: [Technical Field] The present invention relates to a shockproof protection split, and more particularly to an electronic device having an electronic shockproof hard disk. 5 [Prior Art] With the development of the electronics industry, the daily life has been filled with a variety of electronic products, such as: common portable electronic devices and computer devices. In order to provide the ability to store large amounts of data, many of the portable < electronic devices usually use non-volatile memory or hard disk to store data. However, for a portable electronic farm containing a hard disk, it must have a shockproof function to prevent data loss due to the vibration of the portable electronic device when the hard disk accesses the data. 15 For example, when a portable electronic device with a hard disk drive suddenly drops from a height of 15 places, if the portable electronic device does not have a proper anti-shock mechanism, the hard disk of the portable electronic device The disc or head will likely be damaged as a result. Most of the other anti-vibration mechanisms use mechanical shock-proof or shock-absorbing materials to reduce the stress (C3 value) when the hard disk is subjected to impact. However, the use of mechanical shock-proof (or shock-absorbing materials) must take some extra space to reach, and for electronic devices that are light, thin, and short, in the organization. Ten challenges are a big challenge. In addition, mechanical shock protection is a passive protection method that utilizes mechanical components to absorb impact forces in order to reduce the damage of the hard disk drive and not effectively ensure that the hard monument is moved to the proper position. Whether the position of the head and the disc of the disc has been [Explanation] One object of the present invention is to provide an electronic device having a hard disk, which can increase the stability of the hard disk. The security of the watch is fixed: to provide "sub-devices" to prevent data loss. 10 15 Another object of the present invention is to provide a hard monument π with electronic shock protection mechanical shockproof. According to the features of the present invention, the electronic space is provided by a device. The electronic device is provided with a hard mp m. 11 ”, a portable electronic device, or an electric hard disk. Disc, L + analog digital converter, storage unit, disc, heart. The magnetic force detector described above is used to sense and provide a magnetic field strength j. The analog digital converter is electrically connected to the magnetic sensor to receive: field strength, analog to digital converter and convert magnetic field strength to digital sensing 2 . The above processing is respectively connected to the analog digital converter 'cell unit, and hard::, for the processor to receive the digital sense by the analog converter, and (4) according to at least a preset value and digital sensing The value is used to determine the "displacement of the electronic device. If the electronic device generates a spatial displacement within a preset time, the processor issues a control but the edge path controller controls the hard disk to initiate a protection mechanism. 20 1314725 The hard disk drive may also be a micro hard disk, which includes a magnetic head 'moving arm and a disc, and the magnetic head is located at one end of the moving arm, and when the hard disk is opened, the moving arm is controlled according to the control signal, so that the The head is away from the area of the disc. ' The plurality of preset values include a first preset value, a second preset value, and a second preset value. When the difference between the digital sensed value and the first preset value is less than the second preset value, 'hard The disc continues to operate. When the difference between the digital sensing value and the first preset value is greater than the second preset value, and the difference between the digital sensing value and the first preset value is less than the third preset value=, the control device generates the control signal To make the hard disk boot protection mechanism. When the difference between the digital sensed value and the first preset value is greater than the third preset value, the hard maintenance operation is performed. The above-mentioned magnetic sensor must be a three-axis magnetic sensor 15 [Embodiment] For a preferred embodiment of the present invention, reference is made to the internal functional block diagram of the electronic device 1 including a magnetic sensor.

The above-mentioned health-storing unit 14 stores a plurality of preset values (for example, a first preset value (P1), a second preset value (P2), and a third pre- Set the value (p" processing benefit 13 to determine the spatial displacement of the electronic device based on the preset value and the digital sensed value. The preset time (for example: 1 second) produces 20 students-space displacement (translation or drop) (〇·75 meters), and the processor will send a control signal to control the hard disk 15 start protection mechanism. How the processor 13 performs For the related processing of the judgment, please refer to the following description. The above processor 13 can process the digital sensed value of one or two axial components, or sequentially or simultaneously compare the digital sense of the three axial components 1314725 The value is processed. The following will be explained by the case where the processor 13 processes one of the axis components. After the processor 13 receives the digital sensed value (S1), the processor 13 pairs the digital sensed value (S1) with the first pre- The value (p丨) is processed to find a difference (B1), and then the processor 13 further compares the difference (B1) between the digital sensed value (si) 5 and the first preset value (p 1). The second preset value (p 2) is compared with the third preset value (P3). 10 15 If the difference (B1) is smaller than the second preset value (p2), the representative electronic device 1 may be in a normal spatial movement ( For example, the portable device is carried by the user, and the electronic device 1 may also be stationary. State, that is, the electronic device 1 may be placed on the table without being moved, as shown in FIG. 2a. When the processor 13 still maintains its normal operation' and the hard disk 15 is operating at this time, For example, in FIG. 4, the hard disk 15 is a hard disk, which includes a disk 15 and a moving arm 153, wherein the magnetic head 152 is tilted at the __ end of the moving arm 153. The hard disk is accessed by the data, so the mobile arm 153 is controlled by the hard disk control chip to move to the appropriate position on the disk m for f material access. For the processor, due to the digital sensed value ( The difference (bi) between S1) and the first predetermined page value (ρι) is smaller than the second preset value (P2), so the processor i3 still maintains its normal operation, and the hard disk will continue its data access. The right difference (B1) is greater than the second preset value (p2), and the difference 预Si pre-two value (P3)' represents that the electronic device 1 may be severe. Figure 7 The device 1 may fall from the desktop to the floor, such as Figure 2b does not. At this time, the virtual device 13 generates a control signal 'and processes the crying disc 15 to activate the protection mechanism. For example, if data access is in progress at 20 1314725, move arm - = appropriate position for data access. For processing (10) and s, since the difference (B1) is greater than the second (four) value (4)), and the difference is less than the third preset value (p3), the processor 5 10 15 : gate = send to the hard disk 'making continent 156 Leaving the area of the disc 154, you will be able to avoid the electronic device! The impact force generated by the severe spatial displacement will collide with each other, causing data loss or hard disk. A failure has occurred. If the right difference (m) is greater than the third preset value (P3), it represents the electronic device: the magnetic material sensed by the magnetic sensor u. In this case, processor 13 will maintain its normal operation without initiating a shock protection mechanism. The above is a description of how the processing of n 13 is transmitted through the magnetic field intensity sensed by the magnetic sensor to determine whether or not the electron is in motion. In other embodiments, the storage unit 14 may also store a look-up table. The look-up table has a plurality of representative values, each of which represents the electronic device 1 in various motion states (eg, stationary, normal spatial displacement, or severe). The ideal value for spatial displacement, etc.). Therefore, after receiving the digital sensed value, the processor can compare the digital sensed value to the lookup table to find the representative value closest to the digital sensed value, and then the processor 13 finds the same The representative value is output to maintain its normal operation, or to control the hard disk 15 to start the earthquake protection mechanism. It can be seen from the above description whether the sub-device is in a violent situation. The present invention utilizes a magnetic sensor to detect the displacement of the electric space. If so, it first provides control through the processor 20 1314725 (4), and the hard disk can be shockproofed first. Mechanism, which reduces the chance of hard disk failure due to impact, and can increase hard disk stability, prevent data loss, and eliminate the need for a lot of internal space to provide mechanical shock. The above-described embodiments are merely exemplified for convenience of explanation, and the claims claimed in the present invention are described in the above embodiments.
