Technical field

The utility model is related to one kind and (refers to liquid crystal type, including display, monitor, plate display for display Device, similarly hereinafter and display for short) lifting support frame, more particularly to backing thickness be thinned structure lifting support frame.

Background technology

The display screen of the electronic product such as PC and television set is the liquid crystal based on liquid crystal display on the market at present Display be a kind of flat display, because itself can not self uprights, and must by support frame mode will show Device is located at precalculated position.Display bracket is in addition to providing the function of support display, and majority must possess adjustment display The function of height and position, this requires what the lifting module for connecting display in display bracket can be in support frame substantially to erect Lifted into the column or support of setting, and the lifting moving for lifting module is smooth, because ball sliding rail has action Smooth, stabilized structure, durable, movement parts gap is small, the advantages of rock small, therefore is widely used in display lifting support frame In and vertical support installed therein in be used as lift module lifting when support (slide rail is generally used in a pair, mutually Abreast vertically it is mounted near the both sides in display bracket medium-height trestle).Certainly, to make aobvious with greater weight Operate light when showing device lifting, must also there is one can balance the power source of display weight component in support frame, fixed force spring is because of power Value is constant, and structure is extremely simple, compact, cost is low, and footprint is small during drawing work, and is widely adopted, fixed force spring two End is located at support with lifting on module 6a (or interior rail in slide rail, be connected because lifting module with interior rail).

Varied widely as the development of technology is particularly people's aesthetical interest at present, increasingly require display liter The more slimming (the mainly slimming of its medium-height trestle, it is desirable in long and flat plate body shape) of descending branch support, but support frame hair Open up history very long, several generations is thinned, then enter one be thinned will be extremely difficult, the existing skill closest with the utility model at present Its construction of the thin display lifting support frame of art approximately as (refer to Fig. 9,1 shown in), including：

The base of one plate body shape；

One support 7a, is plate body shape, is generally vertically arranged on base, its side has been recessed a storage tank；

Two slide rail 10a, the both sides being respectively arranged in parallel to each other in the storage tank simultaneously are fixed on to form described accommodating On the wall of groove；

One lifting module 6a, including a sliding part 61a, a screen pitching hinge unit, shield itself rotation hinge unit, a company Connect the screen connecting plate of display；Sliding part both sides described in two correspond to slide rail described in two respectively；Screen pitching hinge unit is used to adjust The pitching visual angle of display；Shield the rotation angle that itself rotation hinge unit is used to adjust display itself；

At least certain force spring 8a, each fixed force spring 8a include an a winder 81a and connection end 82a, and institute State winder 81a winding axis general horizontal and parallel to the publicly-owned face where the two slide rails 10a, the connection end 82a With winder the 81a company of the setting sliding part 61a (or on interior rail in slide rail 10a described below) and support 7a respectively；

When the sliding part 61a is slided downwards along the two slide rails guide path, the fixed force spring 8a is corresponding Stretch and keep elastic pulling force constant for balance display gravity, make display can be arbitrarily with the height position required for being parked in Put；

Further to adjust the visual angle of display, what support 7a bottoms had is additionally provided with support rotation hinge unit 91a.

Especially it is noted that slimming of slide rail 10a described in above-mentioned to support is critically important, in its tool of prior art Body includes again：

One outer rail 1a, it is substantially u-shaped in terms of cross section, namely be connected including a disjunctor portion 12a with by disjunctor portion 12a Two general parallel orientations, adjacent tabular raceway plate 11a；The disjunctor portion 12a is generally the homonymy longitudinal direction of the two raceways plate 11a Integrally extension bending interconnection is formed and is connected with the both sides in the support 7a in display lifting support frame at edge；

Rail 2a in one, with a groove portion 21a and a connecting portion 22a, groove portion 21a is plate body shape and is arranged at two rolling Gap is kept everywhere between guidance tape 11a and with outer rail 1a；By rolled portion 21a plate bodys, integrally curved prolong is formed the connecting portion 22a, is used The sliding part 61a in lifting module 6a in connection display bracket.

Two row balls (ball 3a be steel ball) and a corresponding pearl frame 4a, the pearl frame 4a in terms of slide rail cross section substantially U-shaped, between the outer rail 1a and interior rail 2a, its opening direction and outer rail 1a opening direction is towards identical；Two row Each ball 3a in ball 3a is spaced, is accommodated and is held in the corresponding two row receiving hole of corresponding pearl frame 4a；Groove portion Each clamping common respectively contradicts a row ball 3a between the two sides of 21a plate bodys and two neighbouring raceway plate 11a；And interior rail 2a with Outer rail 1a be equipped with the face contacted with each ball 3a corresponding groove-like ball guiding and load raceway it is (each Two row raceways each affiliated are correspondingly formed the passage that two ball 3a are rolled jointly on the interior rail 1a and outer rail 2a of slide rail).

Thus, relatively moved between interior rail a2 and outer rail 1a by the rolling of ball a3, make display bracket Module is lifted by the guiding of ball slide rail raceway along a straight line path shift reciprocately.

But the ball slide rail in the slim support frame of prior art is two row balls and arrangement is contraposition arrangement, i.e., from slide rail Cross section sees that the ball arrangement of two row balls is (assuming that two row balls just respectively have a ball fortune in the slide rail in the prior art Move on the cross section) be：The line of centres of its two ball is along (the thickness direction industry definition of slide rail of slide rail thickness direction For generally perpendicular to the direction of the raceway plate plate face of outer rail two), namely " contraposition " arrangement that ball be referred to as in the industry is arranged is (accordingly We can also tilt on the cross section to the normal direction in the face of the line of centres by two row balls with the slide rail thickness direction The ball arrangement referred to as " dislocation " of one angle is arranged, the slide rail of certain currently available technology there is not yet such a dislocation is arranged, because As two row balls be in dislocation arrangement if in rail 2a will can not be positioned in outer rail, it is stabilized).So that the gross thickness of slide rail For：Locate the interior rail 2a plate bodys between the row ball of diameter+two of the outer rail 1a two raceway plate 11a row ball of thickness+two most Small thickness；Obviously can be still thicker.

The main bottleneck of the slimming of support frame is except there is the arrangement of fixed force spring in slide rail thickness, and in the prior art The winding axis general horizontal of the winder of fixed force spring and parallel to the publicly-owned face where two slide rail, and winder Because being that spring stalloy winding is formed, the diameter of its profile lifting the life requirements of drawing numbers because being unable to very little, therefore Also into the thinned big bottleneck of second support, certainly, existing slide rail also has some other structural factor to hinder subtracting for support It is thin.

Therefore, prior art is limited to these structural factors, limits it in the Display support for having thinner slide rail requirement Use in frame.

Due to the progress of the electronic product such as display bracket mechanism design in recent years, people pursue the support of more and more thinner Outward appearance, therefore the purposes of prior art will be quite limited, it is impossible to suitable for more slim display bracket product.Therefore The improvement of backing thickness reduction how is carried out by existing structure, display lifting support frame of the production with thinner requirement is realized, Turn into one of industry important topic to be solved.

Refer to shown in Fig. 2 to Fig. 8, and emphatically referring to Fig. 7, a kind of three pearls column thin display support frame E classes, it is special Levying is, including：

One support 7, substantially in elongated plate body shape (because slim, so generally plate body shape；Illustrate but do not limit with This, material and shaping are such as shaped using aluminium alloy compression casting, and bottom is used for the cables such as display provided with a big threading hole 75 and walked Line), one lateral plates (are illustrated but are not so limited, according to the side plate face of support 7, big provided with a storage tank 71 being recessed Body position on the upper side is recessed to be formed to plate face thickness direction, and two vertical slots 74 are further opened with for aftermentioned on storage tank 71 described in this example Two connecting portions 22 cross therebetween), the support 7 generally vertically (often has low-angle pitch tilt, but substantially still Vertical setting) set and (be typically that should be arranged on base 9, but be used as independent-lifting mould also according to support when needing 7 Group is substantially erect using without on base 9)；

Two slide rails 10, (two slide rails 10 are parallel to each other and are spaced for the both sides being abreast respectively arranged in the storage tank 71 Certain distance, such as, the general opening of two slide rail 10 towards), each of which slide rail 10 is included again：

One outer rail 1, including two general parallel orientations, it is adjacent set plate body shape raceway plate 11 (general parallel orientation between two raceway plates 11, together When its between a receiving space is formed because alternate), one respectively connect be connected two raceway plates 11 disjunctor portion 12 (for example but Not limited to this：It is in approximate U-shaped, disjunctor portion 12 therein, equivalent to the back cover of U fonts that outer rail 1 is overall such as in terms of cross section Section, the two raceways plate 11 then removes two sections that back cover section is left behind equivalent to U-shaped；The outer rail 1 can integrally be rushed by steel plate Pressing formation；It is general set along face of the disjunctor portion along longitudinal direction several screwed holes or open-work be used for in display lifting support frame Column or support 7 are connected；Its longitudinal two ends of outer rail 1 can set up block, be deviate from the interior rail 2 for stopping mobile)；

Rail 2 (being such as but not limited to this, can be integrally formed by steel plate punched or ferrous based powder metallurgical) in one, with one substantially In the connecting portion 22 of groove portion 21 and one of plate body shape, (connecting portion 22 is used to such as lift module with the part on display lifting support frame 6 etc. are attached), the groove portion 21 is arranged between raceway plate 11 described in two that (groove portion 21 can be that it is mostly in Between it) and keep gap (to be touched because there is relative motion mutually to wipe between the two, so between should having everywhere with the outer rail 1 Gap)；

Three rows of balls and corresponding elongated pearl frame 4, each row ball are arranged along slide rail longitudinal direction, each column ball The each ball 3 included in a plurality of balls 3 (ball 3 such as uses steel ball), each column ball is spaced, accommodates guarantor The corresponding pearl frame 4 is held in (to be such as but not limited to, the structure of pearl frame 4 is the quantity of ball 3 in the row correspondence ball row of band one Receiving hole strip stalloy) on respective amount receiving hole in；From slide rail cross section, the ball of the three rows of balls The heart substantially in isosceles triangle (adhere to separately three rows of balls 3 ball centre ofs sphere linked up with straight line see) arrangement, the groove portion 21 It is common between the plate face of raceway plate 11 described in the one side of plate body and neighbouring one to contradict the ball in isosceles triangle corner point (forming the ball roll channel that common clamping contradicts the row ball), the another side of the plate body of groove portion 21 with it is neighbouring Another plate face of raceway plate 11 between common two balls contradicted in the base angle point of isosceles triangle two (form common clamping Contradict another two ball roll channels of the row ball)；

The height of the isosceles triangle≤(average (average computation if three rows of balls diameter is not waited) of three ball 3 Diameter+3) (㎜) (in terms of slide rail cross section, it is clear that under certain condition, isosceles triangle it is high smaller, it is meant that in top The ball 3 of angle point is more moved to another two balls direction, and slide rail thickness is smaller, also implies that the middle part local sheet of groove portion 21 Body is more bent along slide rail thickness direction to the isosceles triangle base side direction to be protruded；So, with being arranged using two row contrapositions The prior art construction slide rail of cloth is contrasted under the same conditions, and slide rail thickness can be substantially reduced using three rows of balls dislocation arrangement, Through actually showing, the change of dislocation arrangement size is carried out in this formula size interval, can be more beneficial for reducing slide rail thickness direction Size, processing technology is optimal；Slide rail can be made most thin in thickness direction minimum, slide rail as far as possible) (note, such as prior art The contraposition arrangement of two row balls also wants to be thinned and corrects mistakes position arrangement then due apparently to interior rail cannot get the support of triangle ball and can not Holding position is stable, and uses three rows of balls dislocation arrangement that interior rail position obviously can be made to be supported and stabilized, and slide rail One also can be used alone in support frame, what this will be appreciated that)；

The interior rail 2 can carry out reciprocating linear movement through the rolling and guiding of the three rows of balls relative to the outer rail 1 (it is quite obvious natural result)；

The respective outer rail 1 of two slide rail 10 is fixedly arranged on to be formed on the wall of the storage tank 71 respectively；

One lifting module 6, including a sliding part 61 (being grillage like members, such as stamping parts is combined or casting forming), One screen connecting plate 62 (be plate-like piece, such as steel stamping part, for connecting display screen, general lower edges be additionally provided with clamp with Just fast dismounting display use is realized)；Rail 2 in described in corresponding two is respectively fixedly connected in the both sides of sliding part 61 (being generally in both sides) The connecting portion 22 (this example be the connecting portion 22 through the vertical slot 74 stretch out the support 7 it is outer after slided with described Part 61 is connected, the sliding part 61 puts in support 7 with its effect that is connected and is also in turn, visual concrete structure which kind of It is more convenient, more meets the requirements and select)；

At least two (such as this example be 4) fixed force springs 8 (pulling force approximately constant when it is stretched) and above and below at least dividing Two rows set (point four rows, often arrange one above and below such as this example, it is clear that but often arrange also more than one) in the support 7 (such as This example is in the storage tank 71 of support 7), each fixed force spring 8 (being formed by elastic steel sheet winding) includes a winding Portion 81 (the approximate hollow cylinder of profile) and a connection end 82, and the winder 81 winding axis generally perpendicular to the branch Frame 7 plate face (winding axis so selection after, size of the fixed force spring on the direction of backing thickness can greatly reduce, Certain fixed force spring 8 reduces the elastic force for single spring in the backing thickness direction size to be declined, but can be again above and below Multiple rows of accelerate requires that final such arrangement greatly reduces described than prior art meet total spring force Size of the fixed force spring on backing thickness direction, while total force value requirement is still met, so as to realize the super of support 7 It is thin), the winder 81 and connection end 82 respectively the company's of setting support 7 and the interior rail 2 (due to interior rail 2 and the sliding part 61 be connected, and therefore, the connection end 82 is also attached to the part that the sliding support 61 is stretched into the support 7, is shown Right effect is suitable, specifically mainly considers that connection is more convenient reasonable；Surface meeting during as winder 81 due to its work Opposite brackets 7 are rotated, therefore the company of setting of itself and support can select according to concrete structure, such as this example is used in the middle of winder 81 Borehole jack mounted in support 7 fixing axle 72 on, between certain fixing axle 72 and winder 81 provided with plastic wear sleeve pipe come every Pad, the two sides of winder 81 are also typically provided pad that plastic sheet etc. is separated etc. and carry out anti-attrition and prevent from scratching support 7)；When When the sliding part 61 is moved downwards together with the interior rail 2, each fixed force spring 8 by phase strain stretch and keeps elasticity (its pulling force still keeps approximately constant to pulling force when fixed force spring is stretched, and the power of each fixed force spring is added and can substantially be put down Weigh the gravity of display, display is realized in any height and position with stopping, can also be in lifting travel certainly in practical structures Inside set a friction pair to produce extra frictional resistance, position more steady, the descending operation feel for stopping display is more preferable).

Above please simultaneously emphatically referring to Fig. 7 and Fig. 2.

Further, each interior rail 2 further includes (the such as steel plate of transfer strip 23 of a strip substantially vertically disposed Punching press or casting forming), outwards (substantially seeing) one is curved prolongs by the plate body of the groove portion 21 for the connecting portion 22 of the interior rail 2 Formation (is such as but not limited to this：Its curved shape prolonged of one etc. can be according to the corresponding attachment structure of sliding part 61 to be connected It is adapted to)；Screw or open-work (corresponding attachment structure that specifically should with sliding part 61 of the connecting portion 22 provided with connection Adaptation selection)；The connection end 82 of the connecting portion 22 and the fixed force spring 8 is respectively fixedly connected (because upper in the transfer strip 23 Under have multiple rows of fixed force spring 8, directly by the connecting portion 22 therewith correspond to fixation the connecting portion 22 will be made vertically to become It is very long, shape more difficult, connect also more difficult, therefore to carry out switching relay then relatively good by increasing the transfer strip 23, Described its top of transfer strip 23 is connected with the connecting portion 22 to be connected, the institute of the particularly middle hypomere in side then with multiple arrangements up and down The connection end 82 for stating fixed force spring is connected；Certainly transfer strip is integrally extended into by connecting portion 22 also possible, processing is with installing Difficulty all can be larger) (such as, the interior rail 2 is steel stamping part or iron-base sintered metal piece, and the connecting portion 22 in Fig. 8 is exactly Powder metallurgy structure, the shape matching so connected is easily adapted to connected piece).

Further, the disjunctor portion 12 of the outer rail 1 integrally extends curved for the homonymy longitudinal edge of the two raceways plate 11 Song interconnection one is into (for example but not limited to this：It is in totally what is be approximately integrated to make its shape of outer rail 1 in terms of cross section U-shaped, this relatively simple for structure, good rigidity, stably is easy to be used alone, had enough to meet the need；As shown in Figure 2)；From slide rail cross section See, the length for contradicting the raceway plate of isosceles triangle corner point ball is less than the length of another raceway plate (such as Fig. 2 institutes Show, what this will be appreciated that, have few because contradicting ball and showing, it is clear that the raceway plate for only contradicting a row ball can be relatively short A bit, to save material consumption；The outer rail 1 of illustrating is that steel stamping part shapes or rolling forming).

Further, please simultaneously shown in Figure 5 emphatically, in terms of slide rail cross section, the outer rail 1 is divided into two L-shaped Steel plateelement combination (can be so reduced on process for machining and manufacturing because of the difficulty of the small forming difficulty of thickness；Two L shaped plate parts can be steel plate stamping Casting die or rolling forming part), the long sides of two L-shaped corresponds to raceway plate 11 described in two respectively, the short sides of two L-shaped then it is overlapped simultaneously It is connected and constitutes disjunctor portion 12 (rivet can not be shown mutually with small rivet rivet clasp in figure by being connected, certainly also solderable；This is connected short While equivalent to disjunctor portion 12), the two short sides overlapping of L-shaped part described in two is longitudinally arranged on connection display lifting along slide rail The screwed hole or through hole (riveting location of two L part short side overlappings it should be noted that its position should stagger) of support 7 in support frame； Wherein (please referring also to Fig. 8, this can make outer rail 1 in the branch of display lifting support frame to the steel plate thickness of two L shaped plate parts to be different When being installed in frame 7, thin L-shaped part can borrow or make use of the intensity of of support 7 itself to do rear portion backrest to support, and be fixed on branch If frame 7 is gone up sideways but the long edge position of L-shaped can so still ensure that the rigidity of cantilever in the L parts thickness of cantilever, make the totality of outer rail 1 Rigidity and intensity do not decline, namely by distributing the thickness of two raceway plates, are not reduced while being thinned meeting slide rail thickness The rigidity and intensity of slide rail, a point two pieces manufacture are to reduce the difficulty on process for machining and manufacturing, certainly, sometimes due to correspondence branch The structure of frame 7 is limited, and which L-shaped part also needs according to circumstances to do opposite selection to be thicker, and can not only consider rigidity and intensity).

Further, please simultaneously emphatically referring to shown in Fig. 6,8, the vertical side of the edge of the pearl frame 4 of the three rows of balls It is connected as a single entity, makes from gap that is u-shaped in terms of slide rail cross section and being arranged between the interior rail 2 and the outer rail 1 (this is that a kind of three pearls frame 4 links into an integrated entity the structure of formula, and pearl frame semi-finals degree and rigidity can be a shade better, while synchronism is also quite a lot of； But from cross section, because three pearl framves 4 are linked to be a U-shaped, the certain of gap between the periphery of interior rail 2 and outer rail 1 certainly will be tied up Gap width, is correspondingly readily appreciated that, slide rail thickness can increased)；The pearl frame 4 be by sheet metal punching press it is integrally formed or Plastic injection piece is integrally formed.

Further, raceway plate plate face described in the groove portion plate face and two is in the corresponding position contradicted with the three rows of balls Put respectively along longitudinal direction provided with the (raceway appearance usually in the form of shallow slot, such as with the diameter phase of ball 3 of ball raceway When local arc-shaped slot raceway；The guiding that raceway is used for the rolling of ball 3 makes the relatively described position of outer rail 1 of the interior rail 2 steady It is fixed, separation will not be sliped off, while can also carry the effect with dispersion force, when ball 3 and the raceway groove plane-plane contact, it is to avoid Concentrated on stress is mitigated on face a bit, improve contact stiffness and service life, what this will be appreciated that；Certainly interior rail 2 with Being save on outer rail 1 wherein special a certain may still enable the position of the relatively described outer rail 1 of the interior rail 2 to raceway at two It is determined that, but at this moment interior rail 2 and rigidity, the intensity of the relative motion of outer rail 1 can decline after all, and one to the two place stress is also excessively concentrated In material surface a bit, it is bad, it is not recommended that use, be Unify legislation also therefore, it is believed that the raceway of one to the two place raceway Groove still have simply depth be approximately zero).

Further, at least one described fixed force spring (such as this example is 4, then wherein at least should have one) from as Two to three layers of similar elastic steel sheet are brought into close contact compound together winding into (close by similar two to three layers of elastic steel sheet Laminating is overlapping to be combined together, equivalent to one steel disc, and together winding is formed, and is often enclosed and is close to from each other, so that it is overall outer Shape increase substantially but spring tension is corresponding into multiple increase, althoughs note that the fixed force spring of this internal structure quantitatively still It is considered as a fixed force spring).

Further, the pearl frame is provided with stopper section, is touched to be raised the interior rail of motion, drives band and keep away Exempt from voluntarily to slide (slide rail be for lifting, using when outer rail 1 be fixed on support, the then reciprocal lifting, the pearl frame of interior rail 2 4 also and then reciprocal liftings, it is apparent that after more than 4 lifting of pearl frame, it is unavoidable in being rolled because of the self gravitation reason of pearl frame 4 and because of ball 3 There is the reason such as asynchronous and pearl frame 4 is dropped gradually downward, namely the repeatedly relatively described interior rail 2 of the pearl frame 4 after relative movement Degree of overlapping can gradually decrease, at this moment participate in roll work the total quantity of ball 3 will accordingly reduce, so as to reduce interior rail 2 With the quantity of ball 3 supported simultaneously of outer rail 1, rigidity is such as moved in the work of influence slide rail, and display is possible to rock, unstable；Cause This, it is so-called to set backstop, refer to do a stop configurations on the pearl frame 4 that such as local stamped bumps, riveting, welding smallclothes make this Stop configurations interior rail 2 rise movement nearly peak position on can be touched by interior rail 2 gear and be forced drive band it is together upward, i.e., It touches the stop configurations of pearl frame 4 when being and rising to nearly peak every time by interior rail 2 and forces to drive pearl frame 4 to return original again There is position, be unlikely to gradually down to drop, the stop configurations are so-called stopper section).

Further, it is please simultaneously (in figure for the sake of prominent, omitting interior rail 2) shown in Figure 3 emphatically, the stopper section 5 are connected by a hyphen plate 51 (such as, using harder short steel plate strip) and are formed with the upper top of three pearl framves 4 respectively (it is such as but not limited to this：Interval sets three holes of rivet 52 in short steel plate strip, and the upper top of corresponding three pearl framves 4 is also opened up Corresponding rivet hole, is then connected with rivet 52, and also can substitute rivet 52 with welding such as spot welding certainly is connected), when described interior Rail 2 can touch the transverse slat 51 when rising and drive the pearl frame 4 to follow upwards, it is to avoid because pearl frame 4 is back and forth lifted repeatedly and certainly Row gradually falls, while not influenceing the reciprocal elevating movement of the pearl frame 4 again.(this stopper section structure reliably, stably, simply, hold Easily realize, three pearl frame synchronisms are good).

Further, it is please simultaneously (in figure for the sake of prominent, omitting interior rail 2) shown in Figure 4 emphatically, the stopper section 5 are respectively equipped with one and convex to form and (are such as but not limited to this for top on the pearl frame 4 of the three rows of balls：Using at three Top respectively opens up a rivet hole on pearl frame 4, then naturally constitutes projection with the grade rivet clasp of rivet 53, notes after the riveting of rivet 53, with The two sides of pearl frame 4 see, the material distribution of rivet should be more some more than the material away from interior trackside in inner trackside, so as to convex more than material Rise can rail in backstop, while do not influence to lift in the raceway of outer rail 1 again；For another example, if pearl frame 4 is using can be if plastics integral pieces Thereon top in the lump the convex structure of integrated injection molding one formation stopper section 5；Obviously, similar bulge-structure can have a variety of variants； Noting the raised shape can touch on interior rail 2 top to block to guarantee in the raceway of outer rail 1 lifting carriage simultaneously Without being bypassed), the projection can be touched by the interior rail 2 when the interior rail 2 rises and drive the pearl frame 4 to follow Upwards, it is to avoid because of pearl frame 4, back and forth lifting repeatedly and is voluntarily gradually fallen, while not influenceing the reciprocal elevating movement of the pearl frame 4 again (this stopper section is simple in construction, easy realization, but three pearl framves go up and down with different paces and determine synchronization).

In addition, in the display lifting support frame of this example, please simultaneously shown in Figure 7 emphatically, the lifting module 6 is also It is located at including a screen pitching hinge unit 63 between the sliding part 61 and the screen connecting plate 62, for display viewing angles Pitch regulation.
