Description

A micro-power consumption electronic lock provided by a key

technical field

The present invention relates to locks, especially electronic locks.

Background technique

With the development of modern microelectronics technology and computer technology, electronic locks are entering people's social life more and more. Compared with traditional mechanical locks, electronic locks have obvious advantages in many aspects such as confidentiality, safety and convenience.

But existing electronic lock is almost all equipped with battery in the lock, causes the volume of electronic lock is huge, function is limited, kind is monotonous, thereby has limited its popularization and use in social vast family and office. As we all know, the service life of the battery is generally 1-2 years. Therefore, the existing electronic locks inevitably have troubles and uncertainties in battery installation, battery maintenance and battery replacement. If an electronic lock with a battery is not replaced in time due to human negligence, or due to the cold weather and sudden drop in temperature, the electronic lock loses power before it can alarm, or because people are away on business for a long time If people have reported to the police and cannot know, then, the electronic lock cannot be opened due to power loss, and the consequences of prying the door and smashing the lock are very unpleasant.

There are also very few electronic locks that rely on AC mains power to work, so for these electronic locks, there are inevitably problems that may be more troublesome. For example, how to access the AC mains? How to ensure personal safety after the AC mains power is connected to the door or into the lock? How to unlock in case of power outage? etc.

In addition, because the lock is equipped with a battery or has a power supply, it is impossible to make the electronic lock small in size, so it is difficult for them to be used in places where the lock volume is limited, such as drawers, cabinets, bags, machinery and equipment. In some occasions, they cannot be applied to the mortise door locks that have become the mainstream varieties in the world lock market today. This is why the electronic locks that people can see at present are almost all limited to door locks and have never seen the mortise type electronic lock at all.

From the point of view of technical design, existing various electronic locks consume a lot of energy and power of the power supply, which further aggravates the defect of the power supply in the lock. The main manifestations of its large energy consumption and high power consumption are:

1. As long as the existing electronic lock is put into use, no matter whether you open it or not, the power supply in the lock is always connected, and the proportion of energy consumption in this part is quite large.

2. For existing electronic locks, after completing the necessary password communication and password identification each time the lock is unlocked, the power supply in the lock not only undertakes the unlocking drive of the key unlocking device, but also undertakes the reset drive of the key unlocking device. In this way, the electric energy consumed by the two kinds of driving back and forth cannot be ignored.

3. In addition to the above two kinds of energy consumption, the power supply of quite a few electronic locks has to bear the driving of the solid and heavy deadbolt. It is conceivable that this not only consumes more energy from the power supply in the lock, but also requires The power supply in the lock must have sufficient power.

4. The electromechanical driving device of the existing electronic lock is composed of a motor plus a speed reduction device, and the speed reduction device used in the current electronic lock is inseparable from the worm gear. Apparently, in addition to the large volume of this turbo-worm method, the large frictional resistance that cannot be ignored during its own work also requires that the power supply must be able to provide sufficient power and energy.

In a word, existing electronic locks have the above-mentioned many disadvantages because they have batteries or power sources and their large volume, large power consumption and large energy consumption, which limits their application, popularity and popularity in a wider field. promote.

2. One of the electronic lock embodiments of the electronic lockset of the present invention

The present embodiment is an embodiment (see Fig. 6 and Fig. 7) of a drawer lock, certainly it also can be applied to cabinet and luggage etc. In the figure, the contact 20 made of metal conductive material is installed in the keyhole device 25 with insulating material as the carrier, and the contact 20 is provided with a power supply contact that is the only way for the electronic circuit device 31 to get electricity. The position of the contact 20 in the keyhole device 25 corresponds to the position of the contact 6 after the key head 1 is inserted into the key socket 21 . 24 is a back cover, and 22 is a deadbolt, and the keyhole device 25 that contains the contact 20 and the key socket 21 is installed in the unlocking rotary device 29 . The outline structure of unlocking rotating device 29 is as shown in Figure 9, and it is a hollow cylindrical structure that is provided with key jack 21 at one end, is provided with semicircular boss 28 on both sides outside its key jack 21, It is also provided with a protruding tooth 30 for toggling the locking tongue 22 . Unlocking rotating device 29 is installed in the housing 23 as shown in Figure 8, and this housing 23 is provided with the Φ shape through hole 26 that has breach 27, and the semicircle boss 28 of unlocking rotating device 29 is placed on this Φ shape. Through hole 26. Due to the existence of the notch 27 on the shell 23 and the notch 13 on the key, the insertion and extraction of the key head 1 to the key socket 21 can only be carried out at a fixed notch position (see Figure 10). Key head 1 then can't be pulled out (seeing figure 11) during the angle.

FIG. 13 is a diagram of the internal structure of this embodiment with the rear cover 24 removed. Among the figure, the electromechanical driving device is made of a motor 32 connected to a section of flexible silk 36 or flexible ribbon that can be wound around its shaft end 34, and the other end of the flexible silk 36 or flexible ribbon is fixed to the end of the lever 41 arm of force. The motor 32 is electrically connected with the electronic circuit device 31 and is driven by its control current. The electronic circuit device 31 is installed above the lock bolt 22 and is electrically connected with the contact 20 provided in the keyhole device 25 through a flexible wire 38 . The mechanical switch device comprises a lever 41 and a spring 37, wherein the spring 37 is a torsion spring with two tension arms 48 as shown in Figure 12 and with two vertical hooks 45, the vertical hooks (45) The direction is perpendicular to the moment arm 48 and perpendicular to the tension direction of the two moment arms 48 . The spring 37 is located between the lever 41 and the casing 23 and can move flexibly. In order to facilitate the observation of the spring 37, the lever 41 is assumed to be a transparent object in FIG. 13 . In FIG. 13 , a vertical hook 45 of the spring 37 is inserted into a small hole in the arm of the lever 41 and can rotate flexibly, and another vertical hook 45 is inserted into the small hole 55 in the shell 23 and can also rotate flexibly. The lever 41 rotates around the lever shaft 39. Due to the limiting effect of the stopper 44 and the dead bolt 22, the lever 41 has two extreme movable positions, one of which is shown in Figure 13, and the other extreme position is shown in Figure 14. If a straight line (shown in dotted line among the figures) is used to connect the center of the lever shaft 39 and the center of the small hole inserted into the vertical hook 45 on the lever, then the straight line forms an included angle at the two extreme positions of the lever 41 activities, and the shell The aperture 55 position of inserting vertical crotch 45 on 23 is just located on the vertical projection line of this included angle bisector. The lever 41 installed in this way and the spring 37 constitute a mechanical switch device that can be triggered to turn over and maintain its mechanical state after turning over. The lever 41 it includes has two steady-state mechanical positions, that is, the aforementioned two limit positions.

In Fig. 13, the dead bolt 22 is in the locked position, the mechanical switch device or the lever 41 is in the unlocked state, and due to the tension of the spring (as shown by the arrow in the figure), the head of the lever 41 is pressed against the dead bolt 22 and enters the locking position. Below block 70. Now if the unlocking rotating device 29 is rotated, the protruding teeth 30 will be driven to apply force to the recessed notch 42 provided on the dead bolt 22 and try to make the dead bolt 22 move towards the unlocking direction, but the position of the lever 41 is just in time to withstand the block. The block 70, the lever 41 plays a position-limiting effect on the dead bolt 22, so that the dead bolt 22 cannot move.

After a key that allows to open the lock is inserted into the keyhole device 25 of the lock, the electronic circuit device 17 connected to the battery in the key provides power to the electronic circuit device 31 in the lock through the contact 20 of the key contact 6 and the electronic lock and After transmitting the password for unlocking, the electronic circuit device 31 in the lock provides a short pulse control current to the motor 32 to drive the motor 32 to rotate after the password of the identified key is correct. When the motor 32 rotates, the flexible silk thread 36 or the flexible ribbon is wound around its shaft end 34 and a pulling force is generated on the lever 41, so that the lever 41 rotates and at the same time the spring 37 rotates with the vertical hook 45 in the small hole 55 of the shell as the axis. The lever 41 is then flipped to the steady state mechanical position of the unlocked state. At this time, even if the motor 32 stops driving, the head of the lever 41 is pressed against the stopper 44 under the action of the tension of the spring 37 (as shown by the arrow) so that the mechanical switch device or the lever 41 can maintain the steady state in the unlocked state. Mechanical position (see Figure 14). In order to prevent the bolt 22 from pressing the lever 41 when the motor 32 drives the lever 41 so that it cannot move, it is very important to limit the insertion of the key at a fixed position. When the key socket 21 was inserted into the key in the position shown in Figure 13, the protruding teeth 30 on the unlocking rotating device 29 would bear against the dead bolt 22, so that there was a gap between the head of the lever 41 and the stopper 70 so that On lever 41 activity. In Fig. 13, 33 is a limit post, which can facilitate the insertion and extraction of the key at the correct position.

From the above, in Fig. 14, when the lever 41 is turned over to the unlocked state, the unlocking rotating device 29 can be rotated by turning the key, so that the protruding teeth 30 can move the recessed notch 42 on the dead bolt 22 to make the dead bolt 22 slide toward the unlocking direction ; So the slider 40 that is integrated with the dead bolt 22 on the dead bolt 22 also slides to the unlocking direction along with the dead bolt 22 and slides and collides with the lever 41 during the sliding process to generate a reset thrust. Finally, when the deadbolt 22 reaches the unlocked position, the lever 41 has turned over to the non-unlocked state (see FIG. 15 ) to get ready for the next time the deadbolt is limited. At this time, if you continue to turn the key, you can pull out the key at the position shown in Figure 16; and if you turn the key in the opposite direction, you can make the protruding tooth 30 move the dead bolt 22 to the upward locking direction, so that both the dead bolt 22 and the lever 41 are locked. Get back to the locked initial state as shown in Figure 13.

In this embodiment, the mechanical switch device can be replaced by a slider 50 , a spring 37 and a magnet 47 , as shown in FIG. 17 . In the figure, 49 is a slider guide rail, 51 is a limit post, a magnet 47 is located on a slide bar 46 connected with the dead bolt, and the flexible wire 36 or flexible ribbon included in the electromechanical drive device is fixed on the slider 50. Above, the slider 50 is a ferromagnetic substance that can slide in translation in the slider guide rail 49 . In Fig. 17, the dead bolt 22 is in the locked position, the mechanical switch device or the slider 50 is in the unlocked state, and the slider 50 is pressed to the left under the push rod 52 under the pulling force of the spring 37 to limit the dead bolt 22. position, causing the dead bolt 22 to be unable to move towards the unlocking direction. After the key is inserted into the key jack 21 to make the motor 32 obtain the brief drive current for unlocking, the flexible silk thread 36 or flexible ribbon will pull the slider 50 to the far right to make it magnetically contact with the magnet 47 and be attracted, so the slider 50 overturned to the steady state mechanical position of the unlocked state. Now as long as the key is rotated, the dead bolt 22 can be driven to move in the unlocking direction to complete the unlocking. Apparently, when the lock tongue 22 moves in the unlocking direction, it will drive the slide bar 46 to move and separate the magnet 47 from the slide block 50 during sliding. After the slide block 50 is separated from the magnet 47, the slide block 50 will be pressed against the dead bolt 22 under the pulling force of the spring 37 and try to turn over to the steady-state mechanical position of the non-unlocked state to prepare for the next limit to the dead bolt 22 (See Figure 19). When the key is rotated to make the deadbolt reach the locked position, the slider 50 will fully reach the steady-state mechanical position of the non-unlocked state under the tension of the spring 37, thereby limiting the deadbolt 22 and returning to the position shown in Figure 17 The locked initial state of . When the slider 50 limits the lock tongue 22, the slider guide rail 49 plays a supporting role.

3. The second embodiment of the electronic lock of the electronic lock of the present invention

This embodiment is evolved from one of the aforementioned electronic lock embodiments. Get the unlocking rotating device 29 that contains keyhole device 25 and protruding tooth 30 in one of aforementioned electronic lock embodiments and fix a component mounting plate 64 on it, on the mounting plate 64, be installed with contact 20 electrical contacts. The connected electronic circuit device 31, the electromechanical drive device electrically connected with the electronic circuit device 31, and the mechanical switch device driven by the electromechanical drive device; while retaining the housing 23, deadbolt 22 and rear cover in one of the aforementioned electronic lock embodiments 24 basic functional structures, like this, just obtained the present embodiment of another drawer lock.

The side sectional view of the drawer lock of this embodiment is shown in Figure 20, in the figure, the Φ-shaped through hole 26 on the contact 20, the key socket 21, the keyhole device 25 and the shell 23 is the same as that in one of the aforementioned electronic lock embodiments The same as described, the contact 20 is provided with the power supply contact that is the only way to get electricity for the electronic circuit device 31, the position of the contact 20 in the keyhole device 25 is the same as that of the key head 1 inserted into the key socket 21. The positions of points 6 correspond one to one. A sliding slope 71 for resetting the mechanical switch device is provided on the lock tongue 22; the unlocking rotating device 29 is located in the housing 23, and its enlarged view is shown in FIG. 21 . In FIG. 21 , the spring 37 included in the mechanical switch device is located between the lever 41 and the mounting plate 64 , and the column 63 is rigidly connected with the lever 41 and passes through the mounting plate 64 . The same electronics 31 as one of the previous electronic lock embodiments is mounted on the outermost side.

FIG. 22 is an internal view of FIG. 20 with the rear cover 24 removed, and FIG. 23 is an internal view of the electronic circuit device 31 in FIG. 22 removed. In Fig. 23, the electromechanical driving device is to connect a section of flexible silk 36 or flexible ribbon that can be wound around its shaft end 34 by the motor 32, and the other end of the flexible silk 36 or flexible ribbon is connected with the lever 41; Through hole 72 is arranged; Mechanical switch device comprises lever 41 and spring 37, and lever 41 rotates around lever rotating shaft 39, and lever 41 is observed as L-shaped lever from the direction perpendicular to lever rotating shaft 39, and the end of one arm of lever 41 includes A cylinder 63 is perpendicular to the surface of the mounting plate 64 , passes through the through hole 72 and can follow the movement of the lever 41 in the through hole 72 . In Fig. 23, the lever 41 that the mechanical switch device comprises has two stable mechanical positions that can be triggered to turn over and can maintain its mechanical state after turning over. Its working principle and the structure and installation principle of the spring 37 are the same as those of the aforementioned electronic lock The description in one of the embodiments is the same.

Fig. 24 is an internal view after removing the unlocking rotating device 29 in Fig. 23. In the figure, a sliding slope 71 for resetting the mechanical switch device and a force bearing for toggling the dead bolt 22 are provided on the dead bolt 22. Block 74. Dead bolt self-locking device is made of movable push rod 68 and spring 66, and movable push rod 68 rotates around axle 67, and spring 66 presses it to dead bolt 22 all the time. Among the figure, the shape of movable push rod 68 is like a knife, and its blade surface can slide on the partial position on the dead bolt 22, and the upper left corner of movable push rod 68 is provided with one towards shell 23 and can prevent dead bolt 22 to unblanking. The projection 69 moving in the direction is provided with a block 70 matched with it on the dead bolt 22 .

To facilitate observation and understanding of the working principle of this embodiment, it is assumed in FIG. 22 that the electronic circuit device 31 is a transparent object, so its view can also be shown in FIG. 23 . After a key that allows to open the lock is inserted into the keyhole device of the lock, the electronic circuit device connected to the battery in the key provides power to the electronic circuit device 31 in the lock and transmits the unlock code, and the electronic circuit device 31 in the lock recognizes the key. After the password is correct, a brief pulse control current is provided to the motor 32 to drive the motor 32 to rotate. When the motor 32 rotates, the flexible silk thread 36 or flexible ribbon is wound around its shaft end and a pulling force is generated on the lever 41, so that the lever 41 is turned over to the steady-state mechanical position of the unlocked state as shown in Figure 25, even if the motor 32 stops driving , under the action of the tension of the spring 37, the lever 41 can also maintain the steady mechanical position in the unlocked state. Now, turning the key to the unlocking direction has rotated the mounting plate 64 and also rotated the lever 41 at the same time, so the cylinder 63 on the lever 41 pushes the movable push rod 68 away and opens to allow the dead bolt 22 to move to the unlocking direction (as Figure 26). Further turn the key to the unlocking direction, then the lever 41 as a force arm drives the force stopper 74 on the dead bolt 22 through the cylinder 63 and finally the dead bolt 22 is fully opened to complete the unlocking (as shown in Figure 27). After completing the unlocking, the reverse rotation key can extract the key at the gap 27 of the shell Φ-shaped through hole 26, but during the rotation process before the key is extracted, the sliding slope 71 that is located on the dead bolt 22 will collide with the lever 41 The upper cylinder 63 slides and collides to generate a reset thrust so that the lever 41 is reset to the steady-state mechanical position of the non-unlocked state (as shown in FIG. 28 ). No matter whether the key is pulled out or inserted again after the lever 41 is reset, as long as it is turned in the upward locking direction, the protruding teeth 30 arranged on the unlocking rotating device 29 will stir the projection 75 on the dead bolt to make the dead bolt in the upward locking direction. The movement completes the locking of the dead bolt and returns to the initial state of locking as shown in Figure 23.

Similar to one of the aforementioned electronic lock embodiments, in this embodiment, we can replace the mechanical switch device with the composition of the slider 50, the spring 37 and the magnet 47, and the electromechanical drive device can also be replaced by the electromagnet 57. Drive mode, as shown in Figure 30. In Fig. 30, the slider 50 can translate and slide in the slider guide rail 49, and the head of the slider includes a cylinder 63 that is perpendicular to the surface of the mounting plate 64, passes through the through hole 72, and can move in the through hole 72. . On the moving iron 78 of the electromagnet 57, a connecting piece 77 of a ferromagnetic substance is fixed, and the connecting piece 77 is also fixed with the slider 50 to make the moving iron 78 and the slider 50 maintain the rigidity of interlocking translation. Furthermore, a magnet 47 and a spring 37 are fastened to the stop 76 . When the lock tongue 22 is in the locked position, the spring 37 presses the connecting piece 77 so that the slider 50 is in the stable mechanical position of the unlocked state. When the key is inserted into the key jack 21 to make the electromagnet 57 obtain the short-term drive current for unlocking, the moving iron 78 of the electromagnet 57 is attracted and the slider 50 is followed by sliding, so that the connecting piece 77 is attracted by the magnet 47, and then slides. Block 50 is flipped to the steady state mechanical position of the unlocked state shown in FIG. 31 . At this time, turning the key will make the mounting disc 64 rotate, so the slider 50 is pushed away by the cylinder 63 as a force arm in the process of following the rotation of the mounting disc 64 and opens the dead bolt self-locking device so as to move the dead bolt 22 to the unlocking direction. Move and complete unlocking (seeing Figure 32). After completing the unlocking, if the key is reversely rotated, the key can be extracted at the gap 27 of the shell Φ-shaped through hole 26, but during the rotation process before the key is extracted, the sliding slope 71 that is located on the dead bolt 22 will be in contact with the sliding surface. The cylinder 63 on the block 50 slides and collides to generate reset thrust, causing the slider 50 to push the connecting piece 77 to separate from the magnet 47. During the separation process, once the pressing force of the spring 37 is greater than the magnetic field attraction force, the slider 50 will It is turned over and reset to the steady-state mechanical position (as shown in Figure 33) of the non-unlocked state.

Obviously, in this embodiment, when the lever 41 or the slider 50 is in the unlocked state and the deadbolt 22 is in the locked position, the radius of rotation of any part on the cylinder 63 is smaller than that of any part on the deadbolt 22 reaching the housing 23 Therefore, the unlocking rotating device 29 is a free rotating device that can rotate at any angle around the central axis of the key socket 21 in this case. In addition, in order to avoid that the mechanical switch device cannot be driven because it is at the dead point position of the projection 75 on the lock tongue 22 when being driven, the key is limited to be inserted at a fixed position at the notch of the Φ-shaped through hole 26 on the shell 23. Pulling is very important.

4. The third embodiment of the electronic lock of the electronic lock of the present invention

Present embodiment is shown in Figure 34, and this is a door lock embodiment. In the figure, the keyhole device 25 including the contacts 20 arranged outside the casing 23 is electrically connected with the electronic circuit device 31 inside the casing 23 through a wire 38 . The contact 20, the key socket 21, and the keyhole device 25 are the same as those described in one of the aforementioned electronic lock embodiments, and the contact 20 is provided with a power supply contact that is the only way to get electricity for the electronic circuit device 31, The position of the contact 20 in the keyhole device 25 corresponds to the position of the contact 6 after the key head 1 is inserted into the key socket 21 . The electronic circuit device 31 is electrically connected with the electromechanical driving device. The electromechanical driving device includes a motor 32 and a section of flexible wire 36 or flexible ribbon fixed on its shaft end 34. The other end of the flexible wire 36 or flexible ribbon is connected to the mechanical switch device. The mechanical switch device includes a lever 41 and a spring 37 , and the lever 41 rotates around the lever rotating shaft 39 and is limited by the limit column 86 . The lever 41 has two steady-state mechanical positions that can be triggered to flip and maintain its flipped mechanical state. Its working principle and the structure and installation principle of the spring 37 are the same as those described in one of the aforementioned electronic lock embodiments. In the figure, the unlocking rotating device includes an unlocking handle 90 and a clutch device 84 connected to the unlocking handle with two states of "off" or "on". The clutch device 84 can follow the rotation of the unlocking handle 90 in the "on" state The deadbolt 22 is moved. The deadbolt 22 can slide in the guide rail 81, and the rear end of the deadbolt 22 is fixed with a force plate 82 for the clutch device 84 to rotate and unlock. Under the thrust of stage clip 83, dead bolt 22 tries hard to make oneself be in the locked position all the time. Deadbolt 22 is the usual oblique deadbolt with inclined plane in the lockset industry, it can utilize the collision when closing the door to enter in the shell 23 and eject shell 23 automatically and lock when the door is closed.

Figure 35 is an enlarged view of the clutch device 84 in Figure 34. Among the figures, the clutch device 84 includes a rotating core 89 that can rotate in its cavity, and the rotating core 89 is connected with the handle 90 and can rotate together. There is also a blind hole 88 in the core 89 . On the shell of the clutch device 84 there is a projection 87 which can follow the rotation of the clutch device 84 to toggle the dead bolt 22 and a slide block 91 for resetting the mechanical switch device. There is also a through hole on the shell of the clutch device 84, and a movable latch 92 with a limited range of motion and a spring 93 that pushes the movable latch 92 outward all the time are arranged in the through hole. When the movable latch 92 was positioned at the outward limit position, the clutch device 84 was in the "off" state, and now turning the handle 90 would not drive the casing of the clutch device 84 to rotate together; When in the blind hole 88 on the rotating core 89, the clutch device 84 is in the "closed" state, and now turning the handle 90 can drive the shell of the clutch device 84 to rotate together so that the dead bolt 22 moves. In Fig. 34, the mechanical switch device is in a non-unlocked state, and it is a control device that can push the movable latch 92 to reach the "closed" state.

In Fig. 34, when a key allowing to open the lock is inserted into the keyhole device 25 of the lock, the electronic circuit device in the key provides power to the electronic circuit device 31 in the lock and transmits the unlock code, and the electronic circuit device 31 in the lock After the password of the identification key is correct, a brief pulse control current is provided to the motor 32 to drive the motor 32 to rotate. When the motor 32 rotates, the flexible silk thread 36 or the flexible ribbon is wound around its shaft end and a pulling force is generated on the lever 41, so that the lever 41 is turned over to the steady-state mechanical position of the unlocked state as shown in Figure 36 and at the same time the lever 41 on the clutch device 84 The movable pin 92 is pushed into the blind hole 88 of the rotating core 89 . At this time, although the spring 93 on the clutch device 84 tries to push the movable latch 92 outwards, the tension force of the spring 37 is greater than the push force of the spring 93, so even if the motor 32 stops driving, the lever 41 can still maintain this position. The steady-state mechanical position of the unlocked state.

In FIG. 36 , since the clutch device 84 is in the "on" state, rotating the unlock handle 90 rotates the clutch device 84 at the same time. During the rotation process, the clutch device 84 first drives the slider 91 to slide and collide with the lever 41 in the unlocked state so that the lever 41 is turned over to the stable mechanical position of the non-unlocked state, and then the dead bolt 22 is moved to the unlocked position to complete the unlocking (See Figure 37). After completing the unlocking, unclamp the unlocking handle 90, the same as the unlocking handle of a common lock, the unlocking handle 90 will return to the initial state under the action of the panel spring (not shown in the figure), so everything returns to as shown in Figure 34 initial state shown.

In this embodiment, we can replace the mechanical switch device with a lever 41, a spring 37 and a magnet 47, as shown in FIG. 38 . In the figure, the magnet 47 is arranged on a sliding side that can slide relative to the lever 41 on the casing of the clutch device 84, and the lever 41 is a ferromagnetic substance. After the motor 32 gets the short-term driving current for unlocking, the flexible silk thread 36 or the flexible ribbon will pull the lever 41 to make it magnetically contact with the magnet 47 and be attracted, and its attracting force is far greater than the ejection force of the spring 93 on the movable latch 92 And the pulling force of spring 37 to lever 41, so lever 41 is turned over to the steady-state mechanical position (seeing Fig. 39) of unlocking state. Now as long as the unlocking handle 90 is rotated, the sliding side on the clutch device 84 can slide and separate from the lever 41 while driving the dead bolt 22 to the unlocking direction, so that the magnet 47 is separated from the lever 41. After the magnet 47 is separated from the lever 41, under the pulling force of the spring 37, the lever 41 is reset to the steady-state mechanical position of the non-unlocked state.

5. Embodiment of the electronic lock head of the electronic lockset of the present invention

After the electronic lock head of this embodiment is used to replace the mechanical lock head of any mortise type mechanical lock, the original mortise type mechanical lock can be changed into a mortise type electronic lock immediately. Fig. 40 is a side sectional view of this embodiment. The mortice-type electronic lock that becomes after replacing the mechanical lock head is installed on the door as shown in Fig. 41, and Fig. 42 is a side view of Fig. 41. Obviously, this is different from ordinary The installation method and use method of the mortise mechanical lock are exactly the same. In Fig. 41 and Fig. 42, 135 is the panel of the lock, 22 is the dead bolt, 137 is the present embodiment, 21 is the key socket, and 143 is the screw for fixing the lock head. As can be seen from Figure 42, the key socket 21 is located outside the door, and the knob 101 as the unlocking handle in the door is located in the door. Whether it is a mechanical lock or an electronic lock, its task is to turn the dead bolt dial 111 so that the dead bolt 22 can be stirred. Because there are teeth 144 on the dead bolt 22, the dead bolt dial 111 on the lock head can move the dead bolt 22 by one grid every time it rotates.

In Fig. 40, there is a through hole on both sides of the gap 121 in the middle of the shell 23, wherein the right one is called the front hole facing the unlock key, and the left one is called the rear hole facing the knob 101. Unblanking rotating device 29 is located in the front hole of shell 23, and the keyhole device 25 that contains contact 20 and key jack 21 is installed in unblanking rotating device 29, and contact 20, key jack 21, keyhole device 25 and aforementioned The same as described in one of the electronic lock embodiments, the contact 20 is provided with the power supply contact that is the only way to get electricity for the electronic circuit device 31, and the position of the contact 20 in the keyhole device 25 is the same as that of the key head 1 The positions of the contacts 6 after the key is inserted into the key socket 21 are in one-to-one correspondence. The outline structure of unlocking rotating device 29 is as shown in Figure 45, is provided with key socket 21 and two semicircle bosses 28 at its front end, is provided with the projection 145 that is used for torque transmission at its rear end. The unlocking rotating device 29 is installed in the housing 23 shown in FIG. Due to the existence of the notch 27 and the notch 13 on the key, the insertion and extraction of the key head 1 to the key socket 21 can only be performed at a fixed notch position (see FIG. 10 ). When the key head 1 rotates at a certain angle relative to the shell 23 The key head 1 then cannot be extracted (referring to Fig. 11).

In Fig. 40, inside and outside the rear hole of the housing 23, there is a knob device used as the unlock handle inside the door. It is arranged in the back hole of the shell 23, and its thick end is a knob 101 outside the shell 23 with a closed shape.

In FIG. 40 , the unlocking rotating device 29 is engaged with the rotating shaft 110 provided in the knob device through a protrusion 145 and a connecting piece 113 for torque transmission. The deadbolt dial 111 is located between the front hole and the rear hole of the housing 23, and it is engaged with the round tube 108 provided in the knob device.

FIG. 58 is an enlarged view of the knob device separated from the housing 23. In the figure, the end of the elastic reed 13 installed on the driven disk 129 is an elastic bent step.

Fig. 48 is an internal view after the knob 101 in Fig. 40 is cut away. In the figure, the electronic circuit device 31 is located on the outermost side, and the motor 32 included in the electromechanical drive device is beside it. Figure 49 is an internal view after the electronic circuit device 31 in Figure 48 is removed. Or the other end of the flexible transmission belt is connected to the mechanical switch device. A through hole 72 is provided on the mounting plate 64 . When the mounting plate 64 is rotated to the position shown in the figure, the force-bearing block 103 on the driven plate 129 can be seen from the through hole 72 . In Fig. 49, the lever 41 rotates around the lever rotating shaft 39, and the lever 41 is viewed as an L-shaped lever from a direction perpendicular to the lever rotating shaft 39, and the end of an arm of the lever 41 includes an arm that is perpendicular to the surface of the mounting disc 64 and passes through. A through hole 72 and a cylinder 63 movable in the through hole 72 . The lever 41 has two steady-state mechanical positions that can be triggered to flip and maintain its flipped mechanical state. Its working principle and the structure and installation principle of the spring 37 are the same as those described in one of the aforementioned electronic lock embodiments. A wire outlet hole 149 is also provided on the mounting plate 64 for the lead out of the wire 109 .

Figure 50 is an internal view after removing the mounting disc 64 in Figure 49. In the figure, the annular elastic reed 131 with a gap is installed on the driven disc 129, and the end of the elastic reed 131 gap is bent Steps, the bending steps are located on both sides of the force block 103 (see Figure 58). The inner edge on the bending step is provided with a sliding slope that can slide and collide with the post 63 to generate reset thrust when the post 63 slides over its surface and then rotates in the opposite direction. In the figure, the cylinder 63 is in an unlocked state. When it is driven to rotate, it can press and slide over the bending steps of the elastic reed 131 in two directions, and the cylinder 63 slides over the bending steps of the elastic reed 131 The trajectory of the surface is shown by the arrow in the figure. Due to the damping effect of the damping device on the connecting part of the dial, the elastic reed 131 will not move together when the cylinder 63 slides over the surface of the elastic reed 131 .

As can be seen from the foregoing, as long as the key drives the unlocking rotating device 29 to rotate, the rotating shaft 110 will follow the rotation and drive the mounting disc 64 and the lever 41 to rotate together; as long as the force block 103 on the driven disc 129 rotates, the driven disc 129 It will drive the round pipe 108 and the deadbolt dial 111 to rotate together. In order to facilitate observation and understanding of the working principle of this embodiment, it is assumed in FIG. 48 that the electronic circuit device 31 is a transparent object, so its view can also be shown in FIG. 49 . In Fig. 49, after a key allowing to open the lock is inserted into the keyhole device of the lock head, the key rotates in a certain direction under human operation, so that the mounting disc 64 is driven to rotate. During the rotation of the installation disk 64, the electronic circuit device in the key provides power to the electronic circuit device 31 in the lock and transmits the unlock code, and the electronic circuit device 31 in the lock provides a short pulse control current to the motor 32 after the password of the identification key is correct. Thereby, the motor 32 is driven to rotate. When the motor 32 rotates, the flexible wire 36 or the flexible ribbon is wound around its shaft end and generates a pulling force on the lever 41, so that the lever 41 turns over. Thus, when the lever 41 turns over to the unlocked state, it can slide over the step surface of the elastic reed 131 and drive the force stopper 103 to rotate together as a force arm when it rotates in any direction. The deadbolt dial 111 rotates together to realize the unlocking or locking function of the lock head (see FIG. 51 ). Then, because the cylinder 63 of the lever 41 has slid over the elastic reed 131, if the key is rotated in the opposite direction at this time, the sliding slope on the inner edge of the elastic reed 131 will slide and collide with the cylinder 63 to generate reset thrust, so , the lever 41 is reset to the steady-state mechanical position of the non-unlocking state and returns to the initial state.

In order to prevent the key from rotating, the position of the lever 41 when it is driven by the motor 32 happens to be the dead center position that cannot be reversed due to the resistance of the force stopper 103 and the elastic reed 131 . The in-position switch 148 that is pressed and connected by the lever 41 when turned over to the unlocked state. The in-position switch 148 is electrically connected to the electronic circuit device 31 and sends an in-position signal to the electronic circuit device 31 after being switched on. If the electronic circuit device 31 sends a drive current to the motor 32 and does not obtain the in-position signal of the in-position switch 148 within a specified time, the electronic circuit device 31 will send a drive current to the motor 32 again within a certain time interval, so that the lever 41 is actuated again, therefore, there is always a chance that the lever 41 is not actuated in the dead center position. When the lever 41 is driven to turn over to the steady-state mechanical position of the unlocked state, the in-position switch 148 is pressed to send an in-position signal. After the in-position switch 148 sends the in-position signal, the electronic circuit device 31 will stop the motor 32 from driving again. At this time, under the action of the tension force of the spring 37, the lever 41 maintains its stable mechanical position in the unlocked state so that it can slide over the elastic reed 131 and drive the force block 103 to rotate. Practice has proved that due to the existence of the Φ-shaped through hole 26 on the shell and the notch 13 on the key, the key can only be inserted and removed at a fixed position, which will greatly reduce the existence of the driving dead point of the lever 41 .

Similar to the second embodiment of the aforementioned electronic lock, in this embodiment, we can also replace the mechanical switch device with the composition of the slider 50, the spring 37 and the magnet 47, and the electromechanical drive device can also be replaced by the electromagnet 57 drive mode, as shown in Figure 52. In the figure, the slider 50 can translate and slide in the slider guide rail 49, and the head of the slider includes a cylinder 63 perpendicular to the surface of the mounting plate 64, passing through the through hole 72, and movable in the through hole 72. On the moving iron 78 of the electromagnet 57, a connecting piece 77 of a ferromagnetic substance is fixed, and the connecting piece 77 is also fixed with the slider 50 to make the moving iron 78 and the slider 50 maintain the rigidity of interlocking translation. Furthermore, a magnet 47 and a spring 37 are fastened to the stop 76 . When the slider 50 is in the unlocked state as shown in FIG. 52 , the spring 37 presses the connecting piece 77 so that the slider 50 can maintain its stable mechanical position in the unlocked state. When the key is inserted into the key jack 21 to make the electromagnet 57 obtain the short-term drive current for unlocking, the moving iron 78 of the electromagnet 57 is attracted and the slider 50 is followed by sliding, so that the connecting piece 77 is attracted by the magnet 47, and then slides. Block 50 is flipped to the steady state mechanical position of the unlocked state. When the slide block 50 was in the unlocked state, it could slide over the step surface of the elastic reed 131 and drive the force block 103 to rotate together as a force arm when it rotated in any direction. The wheel 111 rotates together so as to realize the unlocking and locking functions of the lock head (see FIG. 53 ). Then, because the cylinder 63 of the slider 50 has slid over the elastic reed 131, if the key is rotated in the opposite direction at this time, the sliding slope on the inner edge of the elastic reed 131 will slide and collide with the cylinder 63 to generate reset thrust. Thus, the slider 50 pushes the connecting piece 77 to separate from the magnet 47. In this way, once the pressing force of the spring 37 is greater than the magnetic field attraction force during the separation process, the slider 50 will be reversed and reset to the stable mechanical position of the non-unlocked state. And return to the initial state. In Fig. 52 and Fig. 53, the function and working principle of the in-position switch are the same as those described above in this embodiment.

In this embodiment, the reset process of the mechanical switch device is realized by the reverse rotation of the key. In FIG. Locking, in the case of pulling out the key without reverse rotation, even if a key that does not belong to the lock is inserted into the lock, there is no need to worry that the lock will be opened. This is because the dead bolt has been locked at this time, and to unlock it, it must be rotated in the direction opposite to the direction of rotation when the key was inserted last time. Like this, the reset of the mechanical switch device that was not completed before the key was pulled out last time will be be done first. And after the key belonging to this lock is inserted into this lock again, because the effect of aforementioned in-position switch 148 can make mechanical switch device be driven again after resetting and finish unblanking.

In order to ensure the safety of locking the dead bolt by turning the knob 101 in the door, in this embodiment, a second reset mechanism that can reset the mechanical switch device is provided as long as the knob 101 is turned. The second reset mechanism includes a sickle-shaped lever 102 and a spring 156 arranged on the driven plate 129, as shown in FIGS. 54 and 58 . Figure 54 is an internal view including the second reset mechanism after the mounting disc 64 is removed, in which the sickle-shaped lever 102 rotates around the axis 155, and one end of it is provided with a cylinder 159, which points to the annular plate of the knob mount 106 (as shown in Figure 58). One end of the spring 156 is fixed on the cylinder 159, and its other end is fixed on the driven disc 129. The lever 102 is always opened outwards under the tension of the spring 156 . In addition, a stopper 128 and a spring post 104 are provided on the side of the driven disk 129 facing the annular plate 106 . FIG. 55 is an internal view of removing the driven plate 129 in FIG. 54 and retaining the stopper 128 on the driven plate 129 , the spring post 104 and the cylinder 159 on the lever 102 . In the figure, the annular plate 106 is provided with two stoppers 127 forming an included angle, two spring posts 157 and a V-shaped boss 158 (see FIG. 58 ). One ends of the two springs 105 are simultaneously fixed on the spring posts 104 of the driven disk 129 , and their other ends are respectively fixed on the two spring posts 157 of the annular plate 106 . Under normal circumstances, due to the symmetrical resultant force of the tension of the spring 105, the stopper 128 on the driven plate 129 is located at the center of the two stoppers 127 of the annular plate 106, and the cylinder 159 on the lever 102 is also located at and pressed against the V-shaped protrusion. The central part of platform 158 depression. When the knob 101 rotates, due to the damping effect of the circular tube 108, the annular plate 106 and the driven plate 129 are misaligned, and the cylinder 159 and the V-shaped boss 158 are also misaligned. Then, the V-shaped curve on the side of the V-shaped boss 158 pushes the cylinder 159 outward to rotate the lever 102 and simultaneously pushes the cylinder 63 to reset the mechanical switch device in the unlocked state, as shown in FIG. 56 . When the misalignment between the annular plate 106 and the driven disk 129 reaches a certain degree, due to the limiting effect of the stopper 127 on the stopper 128, the knob 101 finally drives the driven disk 129 and the deadbolt dial 111 to rotate together, thereby completing The purpose of turning the lock tongue with a knob in the door and ensuring the reset of the mechanical switch device. Obviously, due to the damping effect of the damping device on the unlocking rotating device, even if the cylinder 63 is in a position outside the arc of the lever 102, it can be slid and bumped during the rotation of the knob 101 to reset the mechanical switch device in the unlocked state. As shown in Figure 57. When the knob 101 is rotated and then loosened, the driven disk 129 and the annular plate 106 return to the relative equilibrium position as shown in FIGS. 54 and 55 under the resultant force of the spring 105 tension.
