The access request of mouth, can be written and read by the data transmission circuit.Calculated as long as i.e. USB interface connection is outside
Machine, no matter whether being in write-protect state for accessing wirelessly, the USB interface is all readable writeable shape to the memory cell 201
State.
In the above-described embodiment, specially processor 202 is in response to pressing operation of the user to button, so as to control phase
The circuit answered.It will be understood by those skilled in the art that during implementing, above-mentioned discharge switching circuit 205, wirelessly open
Powered-down road 208 can also be the circuit with microswitch, without the control of processor 202, by each button come straight
Disconnection and the closure of control microswitch are connect, so that each circuit is switched between different states.
Alternatively, authentication chip (not shown), identity are additionally provided with the basis of above-described embodiment, on wiring board
Proofing chip is connected with processor.The authentication chip can be tested the user identity for remotely accessing or closely accessing
Card, if being verified, allows user to access mobile hard disk, if authentication failed, does not allow user to access mobile hard disk.
With reference to specific application scenarios, the implementation process of the mobile hard disk provided the present embodiment is illustrated.
In a specific application scenarios, mobile hard disk is located at the family of user, and mobile hard disk passes through USB interface and electricity
Source adapter is connected, and power supply adaptor switches on power, i.e. mobile hard disk is chronically at "on" position, and mobile hard disk is by wireless
Network interface card logs in mobile Internet.When user is outgoing, such as when going to work, go on business, travelling, user can by mobile Internet without
Line accesses the mobile hard disk.Alternatively, user first can send identifying code to the mobile hard disk, when authentication chip is tested this
When card code is verified, user can remotely access the data in the mobile hard disk.It is directed to when user opens the mobile hard disk
During the write-protect state of accessing wirelessly, user can only then read the data in the mobile hard disk.Thus, the mobile hard disk becomes
The personal Dropbox of user, user can conveniently obtain number in the place that having network from mobile hard disk whenever and wherever possible
According to.
In another specific application scenarios, user carries the mobile hard disk when outgoing, user by the first button,
Second button closes corresponding circuit, reduces the power consumption of mobile hard disk.When user needs to obtain the mobile hard disk by mobile phone
In data, user pass through the first button connect discharge switching circuit so that rechargeable type electrical storage device provides electricity for mobile hard disk
Amount, and wireless switching circuit is connected by the second button so that user can obtain the data in the mobile hard disk.
The mobile hard disk that the present embodiment is provided, by setting wireless communication interface and wireless switching circuit so that user is not
It only can also control whether the mobile hard disk can connect network with the accessing wirelessly mobile hard disk, improve user oneself
Main property；By setting write-protect circuit, when can prevent user radio access hard disk, to the damages of the data on mobile hard disk and
Distort, improve the security of data；By setting discharge switching circuit and rechargeable type electrical storage device so that mobile hard disk is not having
Having can also use when switching on power, by setting radio communication indicator lamp, write-protect indicator lamp and discharge indicating lamp, can be with
Indicate the various states of mobile hard disk；By setting the first button, the second button, the 3rd button, personalization has been provided the user
Operation, be easy to user to mobile hard disk carry out autonomous operation.Thus, the mobile hard disk that the present embodiment is provided, can not only make
The mobile hard disk can be remotely accessed by obtaining user, be used when can also power off, and prevent that data are damaged or usurped during accessing wirelessly
Change, while the autonomous operation of user is realized, so that user conveniently can obtain from mobile hard disk whenever and wherever possible
Access evidence.
Detailed embodiment is used below, and the implementation to rechargeable type electrical storage device is illustrated.
In a kind of possible implementation, rechargeable type electrical storage device includes electric capacity, the diode connected with electric capacity and limit
Leakage resistance.Wherein, diode plays rectified action so that electric current can flow to electric capacity from power control circuit 203, and can not be from
Electric capacity flows to power control circuit 203.
In alternatively possible implementation, rechargeable type electrical storage device is chargeable lithium ion battery or chargeable
Ni-Cr battery.
Alternatively, rechargeable type electrical storage device can be generated heat in charge or discharge, if heat can not shed, it will influence is moved
The normal work of dynamic hard disk.In the present embodiment, for the ease of the radiating of rechargeable type electrical storage device, as shown in Fig. 2 the present embodiment
Rechargeable type electrical storage device is set close to the side of housing 101, in the position of the side correspondence rechargeable type electrical storage device of housing 101
It is provided with the first heat emission hole 109.The position of the upper surface correspondence rechargeable type electrical storage device of housing is provided with the second heat emission hole
110.Thus, rechargeable type electrical storage device has two faces to be radiated, and adds the area of dissipation of rechargeable type electrical storage device, plus
Fast rate of heat dispation.
Alternatively, as shown in Fig. 2 the first heat emission hole 109 is more than the first pre-determined distance with the edge of housing apart from d1, the
Two heat emission holes 110 are more than the second pre-determined distance apart from the edge of housing apart from d2, and the first pre-determined distance, which is not more than second, to be preset
Distance.Specifically, first pre-determined distance is not less than the 1/6 of mobile hard disk thickness.I.e. in the present embodiment, the first heat emission hole
Although, also there is certain safety between the edge of housing in 109 and the edge setting of the close housing of the second heat emission hole 110
Distance, the safe distance can ensure the intensity of housing, it is to avoid two heat emission hole hypotelorisms, cause asking for casing rigidity decline
Topic.
Because the second heat emission hole 110 is arranged on the upper surface of housing 101, and thickness of the width more than housing 101 of housing 101
Degree, the i.e. width of upper surface are more than the width of side, are ensureing the intensity of housing to greatest extent, and ensure the premise of radiating effect
Under, first pre-determined distance is not more than the second pre-determined distance.Alternatively, first pre-determined distance is not less than mobile hard disk thickness
1/6.It will be understood by those skilled in the art that i.e. the first heat emission hole 109 is all higher than movement apart from the distance of top edge and lower edge
The 1/6 of hard disk thickness, so as to ensure that the intensity of housing side.
Finally it should be noted that：Various embodiments above is only limited to illustrate the technical solution of the utility model, rather than to it
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
