In the embodiment that another is exemplary, the part in control module except front electrode 12 and backplate 13 also can be arranged in winding receipt portion 20.Such as, front electrode 12 and backplate 13 are separately positioned on display screen main body 11 on the front and back by modes such as stickups, and by other components of extending into wire in winding receipt portion 20 and control module or model calling.
For guaranteeing that the setting of front electrode 12 and backplate 13 does not affect the normal work of display part 10, such as block the information of display in display part 10, preferably, front electrode 12 and backplate 13 are arranged on the bezel locations of display screen main body 11.
The winding end that display part 10 comprises with winding receipt portion connects and with winding hold relative elongated end.Display part 10 is winding in winding receipt portion 20 from winding end, thus when display part 10 is wound, the area occupied by it is substantially shrunk.Because display part 10 needs to be wound, be therefore arranged on front electrode 12 on display part 10 and the back side 13 also should have corresponding flexibility, such as, formed by flexible material manufacture.
As shown in the figure, each front electrode 12 and corresponding backplate 13 are preferably arranged on, and flexible display screen main body has on identical height and position, thus when display part 10 is wound (as shown in Figure 3), the front electrode 12 in flexible display screen main body 11 front can contact respectively with corresponding backplate 13.Preferably, when front electrode 12 and backplate 13 are all arranged on the bezel locations of display screen main body 11, thus when display part 10 is wound, front electrode 12 contacts respectively at corresponding backplate 13.
In the embodiment of display screen reel system of the present utility model, front electrode 12 and backplate 13 all have the shape of regulation.Such as, Fig. 1 and Fig. 2 shows wherein a kind of electrode structure.Wherein, front electrode 12, on the whole for having the pellet electrode of certain width, to fit or to be pasted onto in display screen main body, and is convenient to contact with backplate 13 when reeling.As shown in Figure 2, front electrode 12 comprises two parts: the Part I of rectangle, and leg-of-mutton Part II.Backplate 13 is also on the whole for having the pellet electrode of certain width, to fit or to be pasted onto in display screen main body, and is convenient to contact with front electrode 12 when reeling.Backplate 13 has rectangular shape on the whole.When front electrode 12 and backplate 13 are arranged on the frame place of display screen main body 11, their width, such as, can set according to the width of the frame of display screen main body 11.
In other unshowned embodiments, the leg-of-mutton Part II of front electrode 12 also can be set to other shapes, and this will illustrate hereinafter.
In a unshowned embodiment, the global shape of front electrode 12 and backplate 13 can exchange.That is, front electrode 12 has rectangular shape on the whole; And backplate 13 comprises two parts, the Part I of elongated rectangle and leg-of-mutton Part II.
As shown in Figure 3, when the display part 10 by display screen reel system is wound, front electrode 12 and backplate 13 are by when starting to contact with each other, and first the Part II of the rectangle of front electrode 12 contacts (see Fig. 5) with backplate 13.This Part I by the rectangle by front electrode 12 is arranged to realize than the winding end of leg-of-mutton Part II closer to display part 10.
Fig. 3 shows the schematic sectional side view of the display screen reel system according to an embodiment of the present utility model.Wherein, display screen reel system comprises display part 10 and winding receipt portion 20, and display part 10 can be wound and be received in winding receipt portion 20, and by backward-coiled around and launch, to stretch out from winding receipt portion 20.
Winding receipt portion 20 comprises: shell 21, and this shell 21 is such as cylindrical shape and comprises opening (not shown), and display part 10 enters into shell 21 by this opening and stretches out from shell 21; Be arranged on the flexible liner 22 inside shell 21; With the supporting construction 23 being arranged on central area, winding receipt portion.As shown in Figure 3, display part 10 is wound and is contained between described flexible liner 22 and supporting construction 23.The damage that flexible liner 22 may cause because of shell 21 contact friction with rigidity for preventing display part 10.
Supporting construction 23 comprises: peripheral support wall; Central rotating shaft; With the multiple telescopic props 24 (such as, there is shown 8) for being connected peripheral support wall and central rotating shaft.Described multiple telescopic prop 24 extends along the radial direction of columnar shell 21 and has identical angular separation each other.In embodiment of the present utility model, telescopic prop 24 can realize by being controlled to provide the structure (such as having the sliding sleeve etc. of driving mechanism) suitable arbitrarily of Telescopic, and peripheral support wall has certain flexibility and elasticity, thus the diameter of peripheral support wall correspondingly can be changed along with the flexible of telescopic prop 24.Display screen main body 11 can be connected to peripheral support wall, thus when supporting construction 23 is rotated by the rotation of central rotating shaft, peripheral support wall driving display screen main body 11 is little by little wound up in supporting construction 23, removes winding from from supporting construction 23.
The principle of work of telescopic prop 24 is: when central rotating shaft such as starts to rotate under the drive of motor (not shown), telescopic prop 24 is placed in shortening state, stretches out to ensure that display screen can be involved in shell 21 or from shell 21 smoothly; When central rotating shaft stops operating, telescopic prop 24 is placed in elongation state, now the display screen of enclosure is sandwiched between flexible liner 22 and peripheral support wall, and be subject to the extruding of flexible liner 22 and peripheral support wall, thus the front electrode 12 of display screen can fully contact with backplate 13.That is, after telescopic prop 24 extends, the laminating of pressurized at least partially of the front electrode 12 and backplate 13 reeled can be made fully to contact, and display part 10 can be fixed by the elongation of telescopic prop 24.In addition, the winding radius of display part 10 can be expanded by the elongation of telescopic prop 24.The type of drive of telescopic prop 24 is including, but not limited to the mode such as electronic, hydraulic pressure, air pressure, electromagnetism.
Fig. 4-8 shows the principle of work of the display screen reel system according to the utility model embodiment, schematically show the position relationship between front electrode 12 under different reeling condition and backplate 13.Fig. 9 is the schematic chart of relation between the electric current measured from the control module display screen reel system corresponding with Fig. 4-8 and coil size or winding degree.
As Figure 4-8, control module has the current detection circuit comprising front electrode 12 and backplate 13.
When display screen is not wound, because front electrode 12 and backplate 13 lay respectively at the front and back of display screen main body 11, therefore front electrode 12 does not contact with backplate 13.Fig. 4 schematically shows this state.
When display screen main body 11 starts to be wound, display screen main body 11 is wound up in supporting construction 23 gradually.Be appreciated that when backplate 13 is wound a circle, it can contact with front electrode 12, particularly, contacts with the Part I of the rectangle of front electrode 12 by Fig. 3.Fig. 5 schematically shows this state.
When display screen main body 11 is wound further, is appreciated that backplate 13 will be wound further and fit with front electrode 12 by Fig. 3, thus occurs intersection 14 therebetween.Fig. 6 schematically shows this state.
Along with display screen main body 11 is wound further, display screen main body 11 is fitted completely by being wound into the Part I of backplate 13 with the rectangle of front electrode 12.Fig. 7 schematically shows the state that backplate 13 is fitted completely with the Part I of the rectangle of front electrode 12.
If in the situation of figure 7, then the display screen main body 11 that reels further, then backplate 13 will fit with the leg-of-mutton Part II of front electrode 12 further.Fig. 8 schematically show backplate 13 not only with the Part I of the rectangle of front electrode 12, the state also fitted with the leg-of-mutton Part II of front electrode 12.
In embodiment of the present utility model, front electrode 12 and backplate 13 are made by having high-resistance material, thus when control module is in channel status, the electric current in control module will fall in predetermined current detection range.Along with constantly carrying out of winding, front electrode 12 constantly increases with (laminating) degree that contacts of backplate 13, the resistance of the entirety that front electrode 12 and backplate 13 are formed is also in continuous change, and thus, current generated in the schematic circuit of Fig. 4-8 intensity is also in continuous change.Such as, when the exposure level of front electrode 12 and backplate 13 becomes large gradually, the resistance of the integrated member that front electrode 12 and backplate 13 are formed will diminish gradually, thus current generatedly increase gradually.Especially, the Part I of front electrode 12 and Part II can be made from a variety of materials, and the resistance of leg-of-mutton Part II is apparently higher than the Part I of rectangle.Like this, when front electrode 12 and backplate 13 bonded to each other by the winding of display screen time, the change of overall electrical resistance will be more remarkable, and this will be described hereinafter.
Shown in Fig. 4-8 five kind of basic status corresponds respectively to interval in Fig. 9 and moment 1. to 5..
State shown in Fig. 4 corresponding to the region in Fig. 9 1..In the diagram, front electrode 12 and backplate 13 do not contact with each other, and corresponding to it is state when such as display part 10 is not wound.In this condition, the current detection circuit shown in Fig. 4 is in off state, now, and the some P on circuit
1and P
2place does not have electric current to pass through, and namely puts P
1the electric current I at place
1with a P
2the electric current I at place
2be zero.This state corresponds to display part 10 and is not wound or is being wound but the low-down state of the degree be wound.
2. state shown in Fig. 5 corresponds to moment in Fig. 9.In Figure 5, front electrode 12 and backplate 13 have just started to contact with each other, and corresponding to it is that such as display part 10 has just opened state when being wound.In this condition, the current detection circuit shown in Fig. 5 is in channel status when just connecting just, now, and the some P on current detection circuit
1and P
2place has electric current to pass through, and namely puts P
1the electric current I at place
1with a P
2the electric current I at place
2all non-vanishing.Now, the resistance that the entirety formed due to front electrode 12 and backplate 13 has is maximum, therefore the current value detected is relatively little.
Based on above-mentioned principle, when P being detected
1and P
2place have electric current by time (I
1and/or I
2non-vanishing), then can judge that display part 10 or is wound.And when detect P1 and P2 place do not have electric current by time (1
1and/or I
2be zero), then can judge that display part 10 is not wound (be namely in and fully stretch out state), or to be wound but the degree be wound is less, to such an extent as to front electrode 12 and backplate 13 not yet contact with each other.
State shown in Fig. 6 corresponding to the region in Fig. 9 3..In figure 6, front electrode 12 and backplate 13 be some overlap, and lap 14 is represented by the shadow region in figure.Corresponding to Fig. 6 is the state (being such as wound to a half) that display part 10 is wound in process.Now, because the area of the lap 14 of front electrode 12 and backplate 13 constantly increases, cause front electrode 12 with when just contacting relative to the two with the all-in resistance of backplate 13 little by little and reduce regularly.Therefore, this time point P
1the electric current I at place
1with a P
2the electric current I at place
2to little by little relative to during the two just contact and increase regularly.By controlling the winding speed (such as at the uniform velocity reeling) of display part 10, now P
1the electric current I at place
1with a P
2the electric current I at place
2to at the uniform velocity increase.As the region in Fig. 9 3. shown in, now, electric current at the uniform velocity increases.
4. state shown in Fig. 7 corresponds to moment in Fig. 9.In Fig. 7, the Part I of the rectangle of front electrode 12 contacts completely with between backplate 13.Now, display part 10 reach the perfect condition reeled completely.
State shown in Fig. 8 corresponding to the region in Fig. 9 5..In this course, the leg-of-mutton Part II in the left side of front electrode 12 starts with backplate 13 overlying contact and degree constantly increases.Because the leg-of-mutton Part II of front electrode 12 has special shape, such as shown in the figure, elongated is triangular shaped, now the resistance of integral part that formed of front electrode 12 and backplate 13 by occur with before change procedure (such as from the 2. state in the linear change of rule 3. state or the change of other rules) inconsistent change, thus the change causing the appearance of the electric current in current detection circuit inconsistent accordingly.Such as, shown in Fig. 9 region 5. in detect electric current value accelerate rise.Specifically, such as, when the Part I of front electrode 12 and Part II can be made from a variety of materials and the resistance of leg-of-mutton Part II apparently higher than the Part I of rectangle time, the resistance of entirety that laminating between backplate 13 and the leg-of-mutton Part II of front electrode 12 will be formed both greatly reducing, thus the overall electrical resistance of resistance significantly reduces, the electric current in the circuit detected is caused obviously to increase.Particularly, when Part I and Part II are made up of the material that resistance is significantly different, the Part II of front motor 12 also can have rectangular shape simply.
Such as, the Part II in the left side of front electrode 12 can have other special shapes in addition to the triangular, makes the electric current in current detection circuit occur this inconsistent change mentioned above as long as it can meet.If detect this inconsistent change of the electric current in circuit, can judge that the state of now display screen main body is overwind state, rotating shaft can be made to stop coiling action.
For achieving the above object, the control module of display screen reel system of the present utility model also comprises: for detecting P in the circuit shown in Fig. 4-8
1and P
2the current detection module of the current value at some place; For the processing module (such as, microprocessor or electronic control unit (ECU) etc.) that the signal or numerical value etc. that receive from current detection module compare, analyze and/or judge; With the controller controlled display screen reel system according to the result of processing module.
As described above, current detection module, processing module and controller all can be integrated in the circuit of display part 10 inside, or it is inner to be arranged on winding receipt portion 20.
Be provided with two front electrodes 12 and two backplates 13 in the above-described embodiments respectively.But, this be the one that provides of the utility model preferred embodiment.In other embodiments unshowned, a backplate 13 that a front electrode 12 also only can be provided respectively and correspond.Correspondingly, such as, current detection circuit in Fig. 4-8 will only have the first half or the latter half, thus only need to detect a some P in current detection circuit
1or P
2the electric current at place.
The embodiment of what but the utility model advantageously provided comprise two front electrodes 12 and two backplates 13.As indicated above, two front electrodes 12 identical except the position difference arranged, simultaneously backplate 13 is identical except setting position difference.Therefore, in winding process, P
1the electric current I that some place detects
1with P
2the electric current I that some place detects
2should remain identical or substantially identical.That is, P
1the electric current I that some place detects
1with P
2the electric current I that some place detects
2difference Δ
ishould to equal zero or close to equalling zero.According to embodiment of the present utility model, a threshold value can be provided, when the electric current I detected
1with electric current I
2difference Δ I when being greater than this threshold value, then illustrate that obvious difference has appearred in the resistance value in upside current detection circuit and downside current detection circuit, due to display screen, this situation may occur that in winding process deflection causes.The value of Δ I is larger, illustrates that display screen degree of deflection in winding process is larger, if do not controlled, then further winding process may cause damage to display screen itself.
Next the control method of display screen reel system will be further illustrated.
Needs illustrate, rate-determining steps hereinafter described can be used alone, and also can be that combination with one another gets up to use.
When determining to need display part winding to enter winding receipt portion, processing module controls corresponding actuating device makes telescopic prop be placed in shortening state, thus telescopic prop unclamps the extruding force for display screen main body 11, be convenient to display screen main body 11 and be involved in winding receipt is intrasystem.
Current detecting part can detect and continuous surveillance comprises the P in the current detection circuit of at least one front electrode described and at least one backplate described
1and P
2the current value at place; When the current value detected is zero, determine that described display part is in deployed condition; And when the current value detected is non-vanishing, determine that display part 10 is in just in reeling condition or reeling condition.
As described above, constantly reel at display part in the process entering winding receipt portion, the electric current I that current detection module detects
1and/or I
2it is constantly change.
According to mentioned above, work as electric current I
1and I
2continuous increase, then can judge that display part is current and be in the process being constantly involved in winding receipt portion; Work as electric current I
1and I
2continuous reduction, then can judge that display part is current and be in the process of stretching out from winding receipt portion.
In addition, under normal circumstances, electric current I
1and I
2value should be identical.If electric current I
1with I
2value remain identical, and processing module judges that the process that is involved in of display part is normal; If electric current I
1with I
2value start to occur deviation, then processing module judges that deflection has appearred in display part in the process of being involved in.If electric current I
1with I
2between difference DELTA I be greater than a threshold value, then processing module judges that the degree of display part deflection in winding process is beyond permissible scope, and this Time Controller controls the winding that relevant mechanism stops display part.The winding of display part is stopped usually realizing by two kinds of modes: (1) stops winding actuating mechanism; (2) telescopic prop is extended, thus the peripheral support wall of 13 of supporting construction against display screen main body 11 surface and apply pressure, thus stop display part further scroll movement.Now, user can correct attitude and/or the position of display part by suitable means (automatically or manually), to eliminate this deflection.
In addition, in electric current I
1with I
2value when remaining identical, system also can pre-set an electric current preset value, and such as, just the reel state of half of this electric current preset value and display part is corresponding.Therefore, electric current I is worked as
1with I
2when equaling this electric current preset value, display part is in the position being involved in half in winding receipt portion just, and when processing module judges this state, controller controls the winding that corresponding mechanism (such as telescopic prop) stops display part.Further, when the winding of display part stops, controller can control the Presentation Function of display part or adjust, such as the picture of full screen display is adjusted to and only shows being exposed on half display part outside winding receipt portion, stop using other half display part being wound and having entered winding receipt portion simultaneously, thus a kind of extra using forestland can be provided, and save electric energy.
In addition, at the end of winding is close, also corresponding control can be performed.Such as:
When the current value that current detection module detects continuously, change regularly time, processing module determines that described display part is in the process reeled normally; When inconsistent change appears in the current value detected, processing module determines that described display part has been in overwind state; When determining that described display part has been in overwind state, controller controls the winding that corresponding mechanism stops described display screen.After the winding stopping display part, controller can control to stop powering to whole display part further, or can close the whole electronic product comprising described display part reel system.
According in a unshowned embodiment of the present utility model, the leg-of-mutton Part II of front electrode 12 mentioned above and the Part I of rectangle can location swaps, thus can judge whether display part excessively stretches out by the unexpected change of electric current.
In addition, according in another unshowned embodiment of the present utility model, the Part I both sides of the rectangle of front electrode 12 can be equipped with such as leg-of-mutton Part II.Thus can not only judge display screen whether overwind by the unexpected change of electric current, can also judge whether display screen excessively stretches out.
So far; describe in detail by way of example and thought preferred embodiment of the present disclosure; but person of skill in the art will appreciate that: when not deviating from the spirit of present disclosure; can carry out further modifications and variations to it, and all such modifications and change all should fall in protection domain of the present utility model.
Such as, although preferred embodiment of the present utility model proposes to adopt one group or two groups of corresponding front electrodes and backplate, the number of electrodes that reality uses can be greater than two groups.Again such as, although preferred embodiment of the present utility model proposes by adopting the electrode with special shape to affect resistance in current detection circuit, but also can adopt the impact that other modes realize for resistance value in circuit, such as can detect the coincidence degree between two electrodes, according to the resistance etc. of coincidence extent control one variohm detected.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
