29 and 30, and these coils are made of suitable conductive winding, normally metal, for example made of copper.Iron core 22 can be any kind known in the industry, and can be solid or layering, and is known as the magnet technical field.Solid core is made by permeability magnetic material usually, and the layering iron core is configured to the many flux channeled layer of magnetic conduction steel usually.Iron core 22 and coil 28 form a magnet like this, and switchably are connected to power supply 100, and the latter is by controller 102 controls, as shown in Figure 1.

The housing of latch assembly 20 is made of the basal part 32 and the lid 50 that are shown in respectively among Fig. 5 and Fig. 6.Basal part 32 comprises a diapire 34 and a sidewall 36, and the latter is made up of three

sidewall sections

38,39 and 40.Enclose district 42 and be positioned on each angle of basal part 32, and form one with it, and be provided with hole 18 for screw 16 usefulness.One L shaped rib 44 extends from the district 42 that respectively encloses that is positioned at basal part 32 fronts.These rib 44 projections toward each other.On the basal part 32 rear portions places diapire 34 and on the sidepiece 40, enclose district 42 accordingly near each and be provided with a pair of seat portion 46.In each one 46, be formed with a columniform depression 47 respectively.There is pair of posts 48 upwards to protrude out and provide guiding piece in diapire 34 central authorities from it, as mentioned below.

Referring to Fig. 6, lid 50 comprises cover plate 51, and cover plate 51 is centered on by side rib 52 at three sides.Each angle of lid 50 is provided with encloses district 54, and comprises the hole 18 that is used for above-mentioned screw 16.Be provided with a pair of seat portion 56 along the back of lid 50, wherein each all has a cylindrical depression 57 that is formed at wherein.On cover plate 51 and be provided with pair of posts 58 in the central,, as described below as guiding piece.

Fig. 7 and Fig. 8 show a representational latch piece that is used for the first embodiment of the present invention.Wherein, latch piece 60 is claw-like, has a base portion 62 and an elongated arm 64, and there is a hook 66 the arm end.The a pair of gudgeon that protrudes out on the contrary 68 is columniform, and stretches out on the contrary from base portion 62 directions.One side of arm 64 is provided with a post 65, one inclined planes 69 and forms a cam surface, and its effect hereinafter will be described in more detail.

Now, show basal part 32 and lid 50, be assembled into housing 31 together with a pair of latch piece 60 is installed referring to Fig. 9.As seen from Figure 9, when lid 50 is placed on the basal part 32, enclose district 54 and will distinguish 42, and aligns mutually in each hole 18 in abutting connection with firmly enclosing.Should point out: if desired, because size is enclosed district 42 and also can be made step-like.Each one 46 and corresponding seat portion 56 are opposed and form a portion to the gudgeon 68 so that each latch piece 60 to be installed.So far, each gudgeon 68 all is received in a corresponding

cylindrical depression

47 and 57, thereby makes latch piece 60 31 commentaries on classics of housing relatively.This installation also is shown among Figure 10, can see that the inclined plane 69 of a pair of latch piece 60 faces with each other, and two also projections toward each other of hook portion 66.Enclose the district and 42 have step-like structure by making, can see, just can provide suitable size so that enclose and distinguish the pivoting action that 42 bottom can not hinder the arm 64 of latch piece 60.Can see also among Figure 10 that screw 16 extends through housing 31.In addition, can see that also lid 50 is installed on basal part 32 and has formed a passage 70 that enters housing 31 inside 33,, see below to settle dead bolt.

The configuration of latch assembly 20 each element is shown in Figure 11.In conjunction with Figure 11 referring again to Fig. 3.Iron core 22 has a pair of hold-down arm 71 and a pair of hold-down arm 73 from fin 26 reverse projections from fin 24 reverse projections.Each arm 71 is equipped with a portion 72, and each arm 73 is equipped with a portion 74.On fin 24, be formed with a pair of cross rib 76 and form a passage 77.Equally, on fin 26, be formed with pair of parallel rib 78, and form a passage 79 betwixt.One pin 80 extends between one group of

arm

71 and 73, and another pin 80 extends between another

group arm

71 and 73.

Referring to Figure 11 and 12, iron core 22 and associated components thereof can be regarded an arm shape spare 23 that is installed in housing 31 inside 33 as, and are held in place and guide by being received in post 48 and 58 (Fig. 5 and Fig. 6) in

passage

77 and 79 respectively.Arm shape spare 23 is pressed into primary importance by compression spring 82, and spring 82 is in each L shaped

rib

44 and 71 extensions of an accepting arm, and its medi-spring 82 is received within the seat portion 72 of arm 71.Referring to Figure 11, can see a representational latch piece 60 has been installed, can between a pair of

seat portion

46 and 56, rotating, and be pressed into lock-out state by compression spring 84.To illustrate now that pin 80 and compression spring 84 1 work makes latch piece 60 in locking with mobile between discharging.

Referring to Figure 13 and 14, can see that when arm shape spare 23 is in primary importance (Figure 13), sells 80 and support inclined plane 69, the power of compressing spring 84 by resistance makes latch piece 60 rotations force them separately.Arm shape spare 23 is pressed into this primary importance by the compression spring with spring constant bigger than spring 84.Thereby under the situation without any other power, arm shape spare will be pressed into housing 31 backward, and latch piece 60 will move into release conditions.Yet, when arm shape spare 23 to inlet 70 when advancing, pin 80 similarly moves forward.This moves into the second place corresponding to arm shape spare 23.When this took place, pin 80 69 moved along the inclined plane, thereby allows compression spring 84 that latch piece 60 is moved to lock-out state, as shown in figure 14.

Behind the structure of the dead bolt 90 shown in having discussed among Figure 15 the most clearly, that the action of electromechanical lock 10 will become is clearer.Dead bolt 90 is the form of a T shape piece among the figure, has a bottom 92 and a top 94, and 94 oppositely stretches out a pair of protuberance 96 from the top.Protuberance 96 forms the shoulder 97 that is fit to by hook portion 66 engagements of latch piece 60, and this will be described below.Be provided with by countersunk 98 and admit screw 99, dead bolt 90 is fixed in the second member part, door for example shown in Figure 1.Should understand dead bolt 90 and form an armature, this is that the electromechanical lock industry is in common knowledge, and dead bolt 90 is formed by a suitable ferromagnetic material.Term " ferromagnetic " means that this object will be by magnetic attraction.In addition, term " protuberance " refers to any concrete member that can be lived by the latch piece operative constraint in this article, can include but not limited to hook, fork, ring, flange, shoulder, otch or the like.

At last, see Figure 16 and 17, just can understand the running of electromechanical lock 10 fully.Among Figure 16, can see arm shape spare 23 (comprise iron core 22,

arm

71 and 73 and sell 80) be compressed spring 82 and be pressed into primary importance so that the pin 80 that acts on the inclined plane 69 forces latch piece 60 separately, thereby compressed spring 84.In this position, latch piece 60 is in release conditions.Dead bolt 90 70 is in by the admittance state by entering the mouth, thereby makes it be received within the inside of a latch assembly 20.Do not have electric current to flow through coil 28, spring 82 remains on release conditions with latch piece 60, so door 12 can be outwarded winding from doorframe 14.Yet as shown in figure 17, when coil 28 had electric current, iron core 22 and coil 28 became an electromagnet, and dead bolt 90 is magnetically maintained.When door 12 moved, this magnetic attracting force moved the power of arm shape spare 23 resistance springs 82 forward towards the described second place, thus make pin 80 along the inclined plane 69 to reach.So spring 84 is depressed into lock-out state with latch piece 60.At this state, the shoulder 97 that is formed by protuberance 96 is lived in hook portion 66 constraints of each latch piece 60, and has mechanically limited dead bolt 90 and left being moved further by the state of admittance.

Can understand from the above mentioned: as long as the intensity of electromagnet is enough big, so that its magnetic force gets final product with compressing spring 84 compressive force that 69 power that act on pin 80 can overcome spring 82 along the inclined plane.By the spring constant of selected spring 82 suitably and 84 and the size on inclined plane 69 (this all is that common mechanical engineer's technical ability is in one's power within the scope), what the power of electromagnet can be than common magnetic force lock is low.This just can cancel used big and stupid electromagnet in existing controlled inlet magnetic force lock.

Should understand the present invention can adopt panoramic latch piece and not exceed scope of the present invention.In addition, also can adopt panoramic arm shape spare and panoramic dead bolt.For example, dead bolt can have the Any shape and the structure that can retrain latch piece.For example as shown in figure 24, be substituted by the protuberance 96 of the alar part that oppositely stretches out, dead bolt 103 can form the hollow housing 105 that has two openings 107 on the face.Thereby the edge of two openings provides the periphery " protuberance " 109 around them.In this situation, the extensible inside of dead bolt 103 and the peripheral protuberance 109 that opening 107 is lived in constraint of entering of latch piece.

Dead bolt also can be designed to hogring or the annulus for the latch piece constraint.Hogring 106 for example shown in Figure 25 is installed on the plate 108 and forms a dead bolt 104.Ring 106 provides " projection " to retrain latch piece.Should see that Figure 24 and 25 only is some examples of dead bolt, and as mentioned above, the structure of panoramic dead bolt all is possible, this will depend on the structure of latch assembly.

In order to provide some examples of other latch assembly, and the various structures that can develop according to the application's principle of the general skilled designer of restriction have anything but illustrated some and can be used as alternative structure in Figure 18 to 23.One second embodiment of the present invention is shown among Figure 18 to 20.Wherein latch assembly 120 is shown in and is installed in the housing 131.Arm shape spare 123 is with the form of plate 124, and at plate 124 upper support electromagnet 125.Spring 182 is interconnected with housing 131, and plate 124 guides in any suitable manner.Plate 124 is furnished with pair of pin 180, and they are received in the cam path that forms in the arm 164 of latch piece 160.This structure has been cancelled the compression spring 84 in first embodiment.

Shown in Figure 18 and 20, spring 182 is pressed into primary importance with arm shape spare 123.In this position, pin 180 slides in cam path 169, forces latch piece 160 to enter release conditions.Owing to do not have magnetic force, dead bolt 90 can move into as shown in figure 18 admittance state, and move the admittance state that breaks away from as shown in figure 20.But when lead 185 was supplied with electromagnet 125 with magnetic current, magnetic force was enough to overcome the power of spring 182, thereby as shown in figure 19, under magneticaction, electromagnet 125 is attached to dead bolt 90.So, to attempt when quilt admittance state shifts out when dead bolt 90, pin 180 slides in cam path 169, effectively latch piece 160 is pushed lock-out state.At this state, the protuberance 96 of dead bolt 90 is lived in hook portion 166 constraints of latch piece 160.

One the 3rd embodiment of the present invention is shown among Figure 21.Can see that electromagnet 225 forms the part of dead bolt 290.Head 294 provides a pair of protuberance 296, is appreciated that dead bolt 290 can make with the core material of the electromagnetic coil that forms electromagnet 225.Under any circumstance, latch assembly 220 comprises an arm shape spare 223, and it is slidably mounted on the post 228, and is exerted pressure by spring 282, as shown in figure 21.Latch piece 260 is pivotably mounted on the relative two ends of the plate 224 on the axle 261, and when being touched by dead bolt 290, is maintained at off-position (as shown in figure 21) by suitable cam face.Helical spring (not shown, but be similar to Figure 22 and 23 described) extend around axle 262, latch piece 260 is depressed into latched position.But because the effect of spring 282, arm shape spare 223 forces cam member 260 to enter the off-position, and is such as mentioned above.When to electromagnet 225 energisings, magneticaction is with web 224 and dead bolt 290.So door 12 is removed the power that makes plate 224 overcome spring 282 from doorframe 14, thereby makes dead bolt latch piece 260 be switched to latched position, as the skilled person after reading this explanation, be understood that now.

At last, referring to Figure 22 and 23, show the fourth embodiment of the present invention.Wherein, latch assembly 320 is tabular, is installed on first member 314 by screw 322, and screw 322 has a matrix 340, is contained in the depression 342 that forms in the latch assembly 320.One spring 382 is pressed into plate 320 primary importance of close member 314.Dead bolt 390 is installed on one second member 312, and during the receiving positions in being in latch assembly 320, abuts against plate 324.Plate 324 links to each other with electromagnet 325, and a pair of latch piece 360 is connected on the axle 361 rotationally, and is depressed into lock-out state by helical spring 384.

As shown in figure 23, when to electromagnet 325 energisings, dead bolt 390 is drawn to plate 324 by magnetic force.The motion that dead bolt 390 leaves member 314 makes the power of plate 324 resistance compression springs 382 and leaves member 314.When this took place, spring 384 worked, and latch piece 360 is gone to lock-out state shown in Figure 23.But when electromagnetic force allayed, first power that is provided by spring 382 was enough to overcome the power of spring 384, thereby plate 324 is pulled to member 314.When this takes place, act on the face 315 at the cam surface 369 of latch piece 360 peripheries, latch piece 360 is gone to release conditions shown in Figure 22.At this, electromagnet can be the part of dead bolt 390 still, and the installed part that is used for latch piece 360 can be a plate that is attracted to magnet, as among the embodiment of Figure 21.
