Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-12, a mobile hard disk with multiple heat dissipation modes includes a mobile hard disk main body, wherein the mobile hard disk main body includes a protection housing 1, a circuit board and a hard disk 3 assembled and matched with each other. The circuit board comprises a control chip 12 and a data and power interface 2, wherein the control chip 12 and the hard disk 3 are positioned in the protective shell 1, and the data and power interface 2 is arranged on the side surface of the protective shell 1.
The control chip 12 is electrically connected with the data and power interface 2 and the hard disk 3 through corresponding connection ports, and can realize data exchange and power acquisition with external data reading equipment through the data and power interface 2.
Common manifestations of the data and power interface 2 are USB, IEEE1394, eSATA, etc.
As shown in fig. 6 to 7, the data and power interface 2 is mounted on the left side of the protection housing 1, and the data and power interface 2 and the hard disk 3 may be connected to the connection port of the control chip 12 by spot welding, which may be understood as a part of the integration of the data and power interface 2, the control chip 12 and the hard disk 3, thereby reducing the occupied internal space of the protection housing 1.
The top side shaping of protection casing 1 has the inside heat dissipation window 4 of intercommunication protection casing 1, and the top side of protection casing 1 still is provided with dust blocking cover plate 5, and dust blocking cover plate 5 is for can controlling the activity setting on the top side of protection casing 1.
In order to make the dust-blocking cover plate 5 not easy to separate from the protection shell 1 when moving left and right, a slide rail 6 is formed on the front side of the protection shell 1 and the rear side of the protection shell 1, a slide block 7 is correspondingly formed on the front side of the dust-blocking cover plate 5 and the rear side of the dust-blocking cover plate 5, and the sliding direction of the slide block 7 on the slide rail 6 is suitable for being the same as the moving direction of the dust-blocking cover plate 5 on the protection shell 1 (the left and right directions are shown in the figure).
The dust cover plate 5 can be moved on the protection shell 1 by sliding the dust cover plate 5, and the dust cover plate 5 mainly moves around three movable states, namely:
a first active state for making the total opening of the heat dissipation window 4 zero, a third active state for making the total opening of the heat dissipation window 4 maximum, and a second active state for making the total opening of the heat dissipation window 4 between zero and maximum.
It can be appreciated that in the first active state, the dust cover plate 5 is a complete cover for the heat dissipation window 4; in the second active state, the dust cover plate 5 is a cover part heat dissipation window 4; in the third active state, the dust-blocking cover plate 5 does not cover the heat dissipation window 4 at all.
In the embodiment of the present utility model, when the dust-blocking cover plate 5 slides on the slide rail 6 through the slide block 7 to form a sliding route, the heat dissipation window 4 is formed by at least one heat dissipation hole 41 extending along the sliding route of the dust-blocking cover plate 5; the illustrated sliding path is a moving path in the left-right direction, and as shown in fig. 2 to 3, the heat dissipation hole 41 has a long shape extending in the left-right direction. At this time, the change in the opening degree of the heat radiation window 4 means that the opening (the portion not covered by the dust flap) of one or some of the heat radiation holes 41 is adjusted in size.
In other embodiments, when the dust-blocking cover plate 5 slides on the sliding rail 6 through the sliding block 7 to form a sliding path, the heat dissipation window 4 may also be formed by a plurality of heat dissipation holes 41 arranged at intervals along the sliding path of the dust-blocking cover plate 5; the illustrated sliding path is a moving path in the left-right direction, and as shown in fig. 5, the plurality of heat dissipation holes 41 are provided at left-right intervals. At this time, the change in the opening degree of the heat radiation window 4 means to adjust the number of the heat radiation holes 41 not covered by the dust flap 5.
Referring to fig. 2, 3 and 7, the first active state, the second active state and the third active state are obtained when the dust cover plate 5 slides to the left area, the middle area and the right area on the sliding rail 6 of the protection casing 1 respectively.
When the mobile hard disk is used for data transmission, the current total opening of the heat dissipation window 4 (namely, the channel of the gas is increased) can be increased by sliding the dust blocking cover plate 5 rightwards, so that the heat dissipation effect can be enhanced; when the mobile hard disk is used completely or heat dissipation is not needed, the current total opening of the heat dissipation window 4 is zero by sliding the dust blocking cover plate 5 leftwards, so that the possibility that dust, fragments and water enter from the heat dissipation window 4 is reduced, and the situation that dust blocks the heat dissipation hole after long-time storage is avoided.
The dust cover plate 5 has a plurality of movable states, and can not cover the heat dissipation window 4 completely and cover the heat dissipation window 4 completely, but also can cover only part of the heat dissipation window 4 according to the use requirement, so that the applicability is better.
When the dust cover plate 5 is just started to be used, the dust cover plate 5 can be in a second movable state, namely, only part of the heat dissipation window 4 is covered, so that a moderate heat dissipation effect is obtained, the current total opening of the heat dissipation window 4 can be controlled under the condition of improving the heat dissipation effect, and the possibility that dust and water enter the protective shell 1 is reduced; when the temperature of the mobile hard disk is higher after a period of use, the dust cover plate 5 can be in a third movable state, namely the heat dissipation window 4 is not covered at all, so that the heat dissipation effect is achieved to the greatest extent. Through the improvement of the mobile hard disk, the heat dissipation degree of the mobile hard disk is adjustable, and a plurality of heat dissipation modes are obtained.
In order to enable a user to better slide the dust cover plate 5, the top side of the dust cover plate 5 is provided with an anti-slip blocking piece 11, the anti-slip blocking piece 11 can be a group of anti-slip convex strips as shown in fig. 3, the intervals between the anti-slip convex strips can be enough for placing fingers of an adult, and when the user places the fingers in the intervals between the anti-slip convex strips, the left and right directions are provided with the anti-slip convex strips for anti-slip blocking.
In the embodiment of the utility model, when the heat dissipation holes 41 are arranged in a strip shape extending leftwards and rightwards, the bottom side of the dust blocking cover plate 5 is also provided with the heat conduction block 8, and the heat conduction block 8 passes through the position of the heat dissipation holes 41 so as to enter the inside of the protection shell 1.
Because the dust cover plate 5 slides left and right, the heat conducting block 8 moves along with the dust cover plate 5, when the dust cover plate 5 moves from the second active state to the first active state and from the second active state to the third active state, the heat conducting block 8 may abut against the leftmost hole wall and the rightmost hole wall of the heat dissipation hole 41, and the active state cannot be changed: during manufacture, the heat dissipation holes 41 may actually extend along the moving path (the left-right moving path in the drawing) of the heat conduction block 8, or the top side of the protection casing 1 may be further formed with an extension section communicating with the heat dissipation holes 41, so that the heat conduction block 8 can smoothly slide along the dust cover 5 in the left-right direction.
Preferably, the size of the heat conducting block 8 is adapted to the size of the heat dissipating holes 41, so that the heat dissipating holes extending left and right form guide rails of the heat conducting block 8 at the same time, and the dust cover plate 5 is more stable when sliding left and right.
After the heat conducting block 8 stretches into the protection shell 1, heat in the protection shell 1 can be quickly conducted to the dust blocking cover plate 5 positioned outside the protection shell 1, so that the heat dissipation effect is better.
To make the heat dissipation efficiency of this heat dissipation path (heat conduction through the heat conduction block) better: install heat conduction mechanism in the protection casing 1, heat conduction mechanism is including installing the mount pad 9 in the protection casing 1, installs elasticity chucking seat 10 on the mount pad 9, elasticity chucking seat 10 extends along the slip route of keeping off dirt apron 5, and elasticity chucking seat 10 is used for carrying out elasticity chucking to heat conduction piece 8 when heat conduction piece 8 arrives, and elasticity chucking seat 10 is heat conduction type elasticity chucking seat.
By means of the direct contact between the heat conducting block 8 and the elastic clamping seat 10, heat in the protection shell 1 can be more efficiently conducted to the dust blocking cover plate 5 through the direct contact between the elastic clamping seat 10 and the heat conducting block 8.
Preferably, when the dust cover plate 5 is in the second movable state and/or the third movable state on the protective shell 1, the heat conducting block 8 is elastically clamped by the elastic clamping seat 10; the second active state and the third active state mainly represent the situation that heat needs to be dissipated, in this case, the direct contact between the elastic clamping seat 10 and the heat conducting block 8 can enable the overall heat dissipation effect to be better, and under the elastic clamping effect of the elastic clamping seat 10 on the heat conducting block 8, the dust blocking cover plate 5 is not easy to generate the situation of false sliding in the second active state and the third active state, so that efficient heat dissipation is ensured. When the dust blocking cover plate 5 is in the first movable state, the heat conducting block 8 is driven to be separated from the elastic clamping of the elastic clamping seat 10, so that the elastic clamping seat 10 is prevented from being in the state of elastic clamping of the heat conducting block 8 all the time, and the elastic clamping force of the elastic clamping seat 10 is effectively maintained at a high value.
Unlike the foregoing, in this embodiment, the heat conduction block 8 may be always in a state of being clamped by the elastic clamping seat 10. That is, when the dust-blocking cover plate 5 is in the first active state, the second active state or the third active state, the elastic clamping seat 10 keeps the elastic clamping of the heat conducting block 8, and the resistance after the position movement is always provided for the dust-blocking cover plate 5, so that the whole is more stable.
The elastic clamping seat 10 comprises two elastic pieces 101 fixed on the mounting seat 9, a gap corresponding to the heat conducting block 8 is formed between the two elastic pieces 101, and each elastic piece 101 elastically extends towards the other elastic piece and elastically clamps the heat conducting block through the elastic extension; the elastic member 101 is a heat conductive elastic member. When the heat conducting block 8 moves between the two elastic pieces 101, the two elastic pieces 101 are pushed first to enlarge the gap between the two elastic pieces 101, the elastic pieces 101 are in an elastic deformation state, and after the heat conducting block 8 enters between the two elastic pieces 101, the two elastic pieces 101 correspondingly clamp the heat conducting block 8 elastically.
As shown in fig. 10, two elastic members 101 are disposed in tandem, and each elastic member extends along a sliding path of the dust cover plate: so as to ensure that the heat conducting block 8 is elastically clamped by the elastic clamping seat 10 when the dust blocking cover plate is in the second movable state and/or the third movable state on the protection shell; or to ensure that the heat conducting block 8 is always clamped by the elastic clamping seat 10.
Preferably, the mounting seat 9 is close to the hard disk, and the elastic member 101 is close to the heat dissipation hole 41.
The mounting seat 9 is preferably a heat conduction type mounting seat; the dust blocking cover plate 5 can be made of aluminum materials with good heat dissipation effect, the mounting seat 9 can be made of aluminum materials with good heat dissipation effect, and the elastic piece 101 can be made of copper sheets with good elasticity and good heat dissipation effect.
Preferably, the mounting seat 9 may be close to a heat generating part of the hard disk 3 or conduct heat with the hard disk 3 through a heat conducting medium, so that the medium may be a heat conducting metal sheet. Therefore, in addition to the movement positioning of the dust cover plate 5, the elastic clamping seat 10 and the heat conducting block 8 are matched, and the elastic member 101 and the heat conducting block 8 also form a heat radiating fin of the hard disk 3, so that the heat radiating area of the hard disk 3 is increased, and the heat radiating effect of the hard disk 3 is better.
It should be noted that, when the heat dissipation window 4 is formed by a plurality of heat dissipation holes 41 extending along the sliding path of the dust cover plate 5, the number of the heat conduction blocks 8 may be configured to correspond to the heat dissipation holes 41 one by one, and the number of the elastic clamping seats 10 may be configured to correspond to the heat conduction blocks 8 one by one.
In the embodiment of the utility model, the mobile hard disk is also provided with an active heat dissipation device, and the active heat dissipation device comprises
A heat radiation fan 13 for fanning the inside of the protection case 1;
an opening detection unit for detecting a moving position of the dust-blocking cover plate 5;
the control unit obtains the current total opening of the heat dissipation window 4 according to the current position of the dust blocking cover plate 5 detected by the opening detection unit, and correspondingly controls the wind speed of the heat dissipation fan 13 according to the current total opening of the heat dissipation window 4, wherein the wind speed control of the heat dissipation fan 13 is shown as increasing the wind speed when the current total opening of the heat dissipation window 4 is increased; the wind speed control of the heat radiation fan 13 is shown as decreasing the wind speed when the current total opening of the heat radiation window 4 becomes smaller.
The heat dissipation window 4 is used as an air outlet channel and/or an air inlet channel of air driven by the heat dissipation fan 13 in the fan heat dissipation process.
When the dust cover plate 5 is moved to enlarge the current total opening of the heat radiation window 4, i.e. the channel pair strain of the gas passing through the heat radiation window 4 is large, the opening detection unit and the control unit make the wind speed of the heat radiation fan 13 correspondingly controlled to be increased at this time, i.e. the wind speed of the heat radiation fan 13 is controlled to be based on the change of the current total opening of the heat radiation window 4. The situations of large wind speed of a small channel or small wind speed of a large channel are avoided, the current total opening of the heat radiation window 4 is reasonably utilized, and the wind speed of the heat radiation fan 13 is reasonably controlled, so that the channel of gas can be correspondingly increased (the current total opening of the heat radiation window becomes large) when the wind speed of the heat radiation fan 13 is increased, the wind speed of the heat radiation fan 13 can be correspondingly controlled and reduced when the channel of gas is reduced, and the cart is avoided.
When the current total opening of the heat radiation window is kept unchanged in the traditional design, even if the wind speed of the heat radiation fan is increased, the current total opening of the heat radiation window is limited, and only a small degree of gas flow increase can be brought; when the current total opening of the heat dissipation window 4 and the wind speed of the heat dissipation fan 13 are simultaneously increased, the increase of the air flow is limited by the heat dissipation window 4 to a smaller extent, and the increase of the air flow brought by the heat dissipation window is to a larger extent, so that the heat dissipation effect can be increased to a larger extent.
When the dust cover plate 5 is slid rightward for indicating that the heat radiation effect needs to be increased, the air speed of the heat radiation fan 13 is controlled to be increased in addition to the opening degree of the heat radiation window 4, so that the provided heat radiation effect can meet the user's requirement.
Through the setting of aperture detecting element for the user only needs to carry out the removal regulation of keeping off dirt apron 5, can realize simultaneously that the aperture of radiator window 4 is adjusted and radiator fan 13's wind speed is adjusted, also more convenient in control regulation.
Preferably, when the position of the dust cover plate 5 is detected to be in the first active state, that is, the cooling fan 13 is controlled to be in a stopped state, so that the wind speed of the cooling fan 13 is zero.
When it is detected that the position of the dust-blocking cover plate 5 is in the first active state, that is, the obtained current total opening of the heat dissipation window 4 is zero, one way to change the wind speed of the heat dissipation fan 13 is to change the rotation speed of the motor of the heat dissipation fan 13:
when the position of the dust cover plate 5 is detected to be in the first active state, a set value which represents the current total opening of the heat dissipation window 4 is obtained and is set as Lmin;
setting a set value Lmax representing the current total opening of the heat radiation window 4 when the position of the dust cover plate 5 is detected to be in the third active state;
when the dust blocking cover plate 5 is moved, the current total opening of the heat radiation window 4 is changed in Lmin-Lmax;
setting the rotation speed of the motor controlling the cooling fan 13 to Smin when the set value of the current total opening of the cooling window 4 is Lmin;
setting the rotation speed of the motor controlling the heat radiation fan 13 to Smax when the set value of the current total opening of the heat radiation window 4 is Lmax;
when the dust flap 5 is moved, the rotational speed of the motor of the radiator fan 13 varies in smin—smax.
Referring specifically to fig. 11, as one embodiment, lmin is 0mm, smin is 0 rpm, and the rotation speed of the motor of the heat dissipation fan 13 is increased in proportion to the current total opening of the heat dissipation window 4, for example, 30 rpm is increased every 1 mm.
Referring specifically to fig. 12, as another embodiment, lmin is 0mm, smin is 0 rpm, and an initial rotation speed Sa is further set; the Smin corresponds to a first movable state of the dust cover plate 5; when the dust flap 5 is in the second and third active states, the rotational speed of the motor of the radiator fan 13 is varied in Sa-Smax, where Sa is greater than Smin.
Sa may be 250 rpm, 280 rpm, 350 rpm, etc., and has a value between 0 rpm and Sa may be also understood as idle speed. When the heat radiation window 4 is opened, the rotation speed of the motor of the heat radiation fan 13, that is, the lowest is kept at the initial rotation speed Sa, and is continuously increased from the initial rotation speed Sa along with the continuous increase of the current total opening of the heat radiation window 4; when the dust flap 5 is changed from the second active state to the first active state, the rotational speed of the motor of the radiator fan 13 is changed directly from the initial rotational speed Sa to Smin.
Preferably, the opening degree detecting unit includes a magnet 14 mounted on the dust-blocking cover plate 5, and a magnetic sensor 15 mounted in the protective housing 1 corresponding to the magnet 14, and the movement amount of the magnet 14 is sensed by the magnetic sensor 15, so that the real-time position of the dust-blocking cover plate 5 can be obtained. The dust cover plate 5 is preferably provided with a mounting seat penetrating one of the heat dissipation holes, and the magnet 14 is mounted on the mounting seat, so that the magnet can be closer to the magnetic sensor, and the detection accuracy is better.

The dust blocking cover plate 5 is also provided with an air port blocking piece 17 corresponding to the opening of the ventilating window 16; when the air port baffle 17 moves along with the dust cover plate 5, the opening degree of the ventilation window 16 is correspondingly changed, and the opening degree change of the ventilation window 16 is the same as or positively correlated with the opening degree change of the heat dissipation window 4; or the air port baffle 17 correspondingly changes the fluency of the air passing through the ventilation window 16 when moving along with the dust cover plate 5, and the fluency change of the air passing through the ventilation window 16 is positively correlated with the opening change of the heat dissipation window 4.

when the dust cover plate 5 moves leftwards, the air port baffle 17 can be leftwards close to the ventilation window 16, and when the dust cover plate 5 moves rightwards, the air port baffle 17 is gradually far away from the ventilation window 16 along with the movement of the dust cover plate 5, so that the smoothness of gas passing through the ventilation window 16 can be increased.
When the elastic clamping seat 10 and the heat conducting block 8 are arranged, as shown in fig. 6-10, the position of the vent 161 is positioned on the right side of the protection shell 1, the cooling fan 13 is positioned between the vent 161 and the elastic clamping seat 10, the cooling fan 13 works to enable air outside the protection shell 1 and close to the vent 161 to be sucked into the protection shell 1, and the cooling fan 13 blows towards the elastic clamping seat 10 positioned on the left side of the cooling fan 13, so that the air can blow through the surfaces of the elastic piece 101 and the heat conducting block 8 and take away heat of other components positioned in the protection shell 1, particularly a hard disk, and finally is discharged from the cooling hole 41, so that the whole heat dissipation effect is better.
