Fig. 4 and Fig. 5 illustrates the structure of auxiliary bat locking device first embodiment of drawer:
Plastic first bearing 10 has the first hole clipping 141 and the second hole clipping 142 that the first buckle 104 and the second buckle 105, first buckle 104 and the second buckle 105 fasten active rail 14 tail end respectively, thus the first magnetic part is fixed in active rail 14.First bearing 10 has two pieces and is parallel to each other and the plane of the first wallboard 101, first wallboard 101 of equidistantly arrangement and the longitudinal axes parallel of active rail 14, and the plane of two piece of first wallboard 101 is also all simultaneously perpendicular to the horizontal plane of active rail 14 in the present embodiment; Two piece of first wallboard 101 all assembly has the first magnet 102, first magnet 102 to be permanent-magnet steels of square sheet, buries when injection moulding the first bearing in the first wallboard 101; It is identical and all perpendicular to the first wallboard 101 plane that the magnetic pole of two piece of first magnet 102 points to (i.e. axis of magnet sensing).In Fig. 5, the first magnet 102 is magnetic north pole N towards the one side in reader direction.
Plastic second bearing 11 has the 3rd buckle 114, second magnetic part and fastens the 3rd hole clipping 121 of retaining rail 12 tail end by the 3rd buckle 114 and be fixed in retaining rail 12.Second bearing 11 has three pieces and to be parallel to each other and the second wallboard 111, second wallboard 111 of equidistantly arrangement upwards extends from the base portion of the second bearing 11; After second bearing 11 and the first bearing 10 all install, the second wallboard 111 of the second bearing 11 is parallel to the first wallboard 101 of the first bearing 10; Three piece of second wallboard 111 all assembly has the second magnet 112, second magnet 112 to be also the permanent-magnet steel of square sheet, and it is identical and point to identical with the magnetic pole of the first magnet 102 that the magnetic pole of three piece of second magnet 112 points to (i.e. axis of magnet sensing).In Fig. 5, the second magnet 112 is also magnetic north pole N towards the one side of reader.When the first magnetic part along with the movement of active rail near the second magnetic part time, the wallboard neutral of the first wallboard 101 and second wallboard 111 cross-entry the other side, in whole effective mobile distance, the first magnet 102 is adjacent with the second magnet 112 alternating parallel and to be separated by and non-interference.
Fig. 6 illustrates the structure of auxiliary bat locking device second embodiment of drawer:
Plastic first bearing 10 is also utilize the first buckle 104 and the second buckle 105 to be fixed in active rail 14.First bearing 10 has the first magnet 102 one piece of first wallboard 101, first wallboard 101 being embedded with one piece of disc; First magnet 102 is permanent-magnet steels, and its magnetic pole directed in orthogonal is in the first wallboard 101 plane.
Second embodiment and the first embodiment difference are that the second bearing 11 and two piece of second wallboard 111 are directly extended by the tail end of retaining rail 12 and bending forms, and thus two panels second magnet 112 is all steel plate material, and namely the second magnet 112 is paramagnets.Second magnet 112 is attracted each other with the first magnet 101 by generating magnetic when it is close at the first magnet 101.
See Fig. 7 and Fig. 8, when drawer as shown by arrows in FIG. direction move to from right to left be about to clap co-bit put time, first magnet 102 and the second magnet 112 attract each other, in the neutral that first wallboard 101 is tried hard to as far as possible between intrusion two piece of second wallboard 112, even if this attraction f makes the drawer panel when the spring of drawer returning device shows weak and weary also can be adjacent to Bu Liu gap, furniture front.The magnetic line of force that first magnet and the second magnet produce always is tried hard to look for the shortest path and is completed closed-loop path, so the axis of magnet (in Fig. 7, the S-N of the first magnet 102 is with arrow straight line) and the axis of magnet (in Fig. 7, the S-N of the second magnet 112 be with arrow straight line) of the second magnet of the first magnet is abundant close but do not align when drawer should be made completely closed during the mutual stroke of the first bearing and the second bearing in the auxiliary bat locking device of design drawer, namely maintain state shown in Fig. 8.
Fig. 9 and Figure 10 illustrates the detailed description of the invention of the auxiliary closing device of drawer, this embodiment is substantially identical with auxiliary bat locking device first embodiment of above-mentioned drawer from contour structures, and difference is that the setting-in direction difference of the first magnet or the second magnet makes the magnetic pole of all second magnets point to and all points to contrary with the magnetic pole of the first magnet.In Figure 10, the first magnet 102 is magnetic north pole N (the first magnet 102 direction in two the first wallboards 101 is consistent) towards the one side of reader; Second magnet 112 is south magnetic pole S (the second magnet 112 direction in three the second wallboards 111 is consistent) towards the one side of reader.Because drawer assists closing device to have longer stroke, thus the first wallboard 101 of the first bearing 10 is long, strengthens bridge 106 to improve their rigidity so be manufactured with between two piece of first wallboard 101.
See Figure 11, the axis of magnet of the first magnet 102 aligns with the axis of magnet of the second magnet 112, and this is a critical localisation, is in a labile state at the auxiliary closing device of this position drawer.Under this critical condition, magnetic field repulses power between first magnet 102 and the second magnet 112 always does one's utmost to make the first wallboard 101 to right translation thus away from the second wallboard 111 (as shown in figure 12), or does one's utmost to make the first wallboard 101 to left thus more invade the neutral (as shown in figure 13) between two piece of second wallboard 111.
When drawer is closed inwards from pull-out state, when moving to close to critical localisation, drawer can be subject to an outside repulsive force f, at this moment user needs to strengthen a little thrust and goes to overcome this repulsive force, once cross critical localisation, repulsive force between first magnet 102 and the second magnet 112 overturn at once, thus orders about drawer continuation and draw close inwards, and user can experience the trend that drawer is inhaled into.
Otherwise, when the drawer of closing will be opened, first user can experience the repulsive force f of antagonism drawer pull-out, at this moment user needs to strengthen a lower pulling force a little and goes to overcome this repulsive force, once cross unstable position, repulsive force between first magnet 102 and the second magnet 112 overturns immediately, thus orders about drawer outwards movement, and user can feel that drawer is ejected fast.
See Figure 14, drawer of the present invention auxiliary bat locking device and drawer assist closing device except being arranged on drawer guideway 12/14, also can be arranged on drawer rear wall 15 and drawer cabinet rear wall 16, this mounting means also produces with the same technique effect of above three embodiments.
Several embodiment describes preferable configuration of the present invention above.In other embodiment, first magnetic part and the second magnetic part can install one group or install many groups, first magnetic part and the second magnetic part can exchange installation site, can also install a damper additional and make drawer panel slowly clap conjunction in the auxiliary closing device of drawer.
The common ground of the auxiliary bat locking device of drawer of the present invention and the auxiliary closing device of drawer is: the axis of magnet of the first magnet, the second magnet points to all perpendicular to the moving direction of drawer.This Magnetic force tracting structure compared with the axis of magnet of two magnets is set to the magnetic circuit identical with the moving direction of drawer construct have larger superiority because the tractive force of the latter can along with between two magnets distance increase and sharply decline; It is relative with different in nature pole-face that such as two panels diameter is about 2 centimetres, thickness is about the Ru-Fe-Mn magnet steel of 5 millimeters, when two magnet steel pole-face distances are 1 millimeter, both attractions can reach the order of magnitude of kilogram, but when two magnet steel pole-faces reach beyond one centimetre apart, attraction just reduces by two orders of magnitude than original.Experiment proves that the Magnetic force tracting structure of the present invention characteristic that attraction (or repulsive force) declines with distance growth in several cm distance will ease too much, thus can provide better operating handle and in the design and assembling of product, provide less size restriction.
