Abstract
Description
[Technical Field]
[0001] The present disclosure relates to the field of electric door locks, and more particularly to an electric door locking device and an electric door lock that is powered from the door frame side or from the door instead of the door lock. [Background technology]
[0002] Smart electronic door locks have been used in commercial and residential buildings for many years with some success. The ability to open doors without relying on a physical key has gained widespread acceptance. Some smart electronic door locks also offer remote locking and unlocking capabilities for user convenience. Furthermore, the key code on a smart electronic door lock can be quickly and easily changed by the user. Changing the physical lock or key involves a more complicated process, such as hardware modification. Furthermore, while physical keys can be lost, smart electronic door locks can use key codes or biometric indicators, such as fingerprints, instead of physical keys.
[0003] However, despite these advantages, current state-of-the-art smart electronic door locks still have some drawbacks. For example, many electronic door locks are battery-powered, requiring the batteries in the door lock to be replaced periodically. Also, loss of power due to an uncharged battery can lock a user out of the building.
[0004] Another drawback of current technology electronic door locks is that electronic circuitry, mechanical motors, and other components are located on the door and / or door handle, which can be damaged or stop functioning due to the force of the door slamming when opening and closing.
[0005] Furthermore, current smart lock technology has limited door handle and lock hardware options. Smart electronic door locks require dedicated door handles that are specific to a specific smart lock, so standard door handles and door handles with various designs cannot be used with current electronic door handles. This limited design of smart lock door handles limits the design options and aesthetic requirements for building owners.
[0006] Additionally, many smart lock devices that are hardwired to a power source require drilling a hole in the door to allow the wiring to pass through. Drilling a passageway for wiring through a door can be difficult, especially for fire doors with specific requirements, and in some cases, drilling a hole is not possible. Wiring to an electronic lock within a door may require a custom door or other door customization. A smart lock that is hardwired to a building's power source or other power source and allows the use of standard doorknobs and standard doors without the need for customization would be desirable.
[0007] Therefore, there remains a great need for an electronic smart door lock that allows the use of standard doorknobs and standard doors without requiring holes to be drilled in the door to accommodate wiring to the electronic lock. There is also a need to wire the smart lock to a continuous power source to avoid damage to the electronic lock components due to impacts to the door when opening and closing the door. Summary of the Invention
[0008] The present disclosure aims to solve at least one of the technical problems existing in the current technology and further provides many advantages. Accordingly, the present disclosure provides an electronic door lock device that is powered by a power source 40, including but not limited to, building power, solar power, a rechargeable lithium battery power source, an external power source not from the building, power generated inside the lock device, wireless charging via contact or contactless charging of the lock device, or other reliable power sources, thereby improving the continuity of use and overall user experience of the electronic smart lock.
[0009] The present disclosure also provides an electronic door lock device and / or electronic door lock in which the electronic components, or at least some of the components, are located on the strike plate side of the door frame rather than inside the actual door. This arrangement provides flexibility in using standard door handles that would not otherwise be used with electronic door locks. The electrical wiring connections of the present disclosure are made through the strike plate and do not require the involvement of the door itself. Having the wiring in this area allows for increased flexibility in using any door without modifying or drilling holes for wire passage. Additionally, locating the components and wiring on the outside of the door avoids the risk of the door moving when opening and closing, potentially cutting electrical wiring or damaging electrical components.
[0010] In one aspect, the extension block moves a secondary latch that locks a cam to prevent the door handle from rotating when the door is locked. The cam contacts a link strip that engages with the lock tongue to lock the door. The electronic door lock is unlocked when an electronic key is entered into the device. The electronic key may be a fingerprint, password, user interface input, wireless token, key card, retina scan, biometric reader, facial recognition technology, NFC, RFID, radio frequency remote control, etc. After the electronic key is entered, an electrical module drives the extension block to retract, and the secondary latch spring extends the secondary latch. When a user rotates the door handle shaft, the secondary latch disengages from the cam groove, allowing the cam to rotate. The rotation of the cam drives the link strip to move, which drives the lock tongue to retract from the strike plate, unlocking the door.
[0011] In another embodiment, a blocking block moved by an electromagnetic module may be used to lock the cam. The distal end of the blocking block is inserted into a groove in the cam to lock the cam. The blocking block may be moved toward the cam by a blocking block spring, electromagnetic force, or the like. When an electronic key is input and the electromagnetic module generates a magnetic field that moves the blocking block toward the electromagnetic module, the door is unlocked. When the blocking block disengages from the cam, the cam rotates freely. The rotation of the cam drives and moves a link strip, which drives the lock tongue to retract from the strike position, unlocking the door.
[0012] The present disclosure also provides a door lock including the above door locking device, which includes a deadbolt with a locking tongue and a movement mechanism that may or may not include a cam and / or a printed circuit board assembly (PCBA), depending on the implementation.
[0013] A door lock device according to an embodiment of the present disclosure includes:
[0014] The lock includes a strike assembly and a lock body. The strike assembly includes a power module, and the power module operates as either an electric power module or an electromagnetic power module. That is, the power module is an electric power module or an electromagnetic power module.
[0015] The strike assembly further includes an extension block disposed on the electric power module that drives the auxiliary latch, or a blocking block outside the electromagnetic power module, that is used to lock the cam. The cam can be connected to a door handle shaft and a standard door handle or any door handle.
[0016] The lock body includes a cam that can rotate or move around its center. The cam center defines a hole through which the door handle shaft can pass. The cam further defines a groove into which either the distal end of the auxiliary latch or the distal end of the blocking block can enter to lock the cam. The cam also has a plurality of protrusions that move in a circular directional path or other motion when the door is locked or unlocked.
[0017] Furthermore, depending on the implementation, the locking device may further include a cam locking member. The cam locking member may be either an auxiliary latch or a blocking block disposed between the power module and the cam for engaging a groove in the cam. The link strip contacts multiple protrusions on the cam, and movement of the linked strap is controlled by movement of the multiple protrusions. A locking tongue mechanism controlled by movement of the link strip may also be included.
[0018] The locking tongue mechanism may also include a locking tongue body having a locking tongue, a locking tongue spring disposed in the body, a locking tongue positioning piece, and a locking tongue cap. The locking tongue body contacts a link strip, and the link strip may be disposed between the cap and the locking tongue positioning piece. The locking tongue can be retracted and extended into the door frame strike plate. When a door in the door frame is closed, the locking tongue extends into the door frame strike plate, and the cam lock member moves toward the cam and engages with the groove to lock the cam, preventing the cam from rotating and maintaining the door locked.
[0019] Furthermore, depending on the implementation, when the electronic key is entered wirelessly, through a user interface, or by other means, the expansion block moves toward the electrical module, releasing the distal end of the auxiliary latch from the cam groove, or the electromagnetic module generates a magnetic field that moves the blocking block closer to the electromagnetic module, releasing the distal end of the blocking block from the cam groove. Rotating the doorknob shaft allows the cam to rotate freely, moving the link strip and retracting the lock tongue from the strike plate, unlocking the door.
[0020] Door locking devices according to embodiments of the present disclosure may also have at least the following beneficial effects: No drilling or wiring is required inside the door. Any door can be used with any doorknob or door design with the present disclosure. Electronic door locking devices of the present disclosure do not require battery replacement. Electronic components and hardware are removed from the door, reducing the risk of damage from the door being forced closed or opened. Users can maintain other benefits of current electronic door locking devices.
[0021] According to some embodiments of the present disclosure, an electronic locking device includes:
[0022] a power module for driving only the expansion block or the blocking block that contacts the auxiliary latch;
[0023] and a cam for receiving the door handle shaft. The cam has a protrusion for moving the link strip. The cam further defines a groove, and a distal end of the auxiliary latch or a distal end of the blocking block engages with the groove to lock the cam and the door.
[0024] When the electronic key is entered, either the auxiliary latch or the blocking block is released from the cam groove, allowing the cam to rotate and move a link strip that releases the lock tongue to open the door.
[0025] In yet another embodiment, an electric door locking device includes a strike assembly and a deadbolt assembly disposed around a door frame and a door, and a user interface or electronic key for controlling the electric door locking device. The strike assembly includes a power source for supplying electricity to a strike electrode or energy transmission end. The strike electrode or energy transmission end has an opening on one side of the door frame. The deadbolt assembly includes a deadbolt electrode or energy receiving end, a movement mechanism, and a locking tongue. After the door is closed, the power source supplies electricity to the strike electrode or energy transmission end, which energizes the deadbolt electrode or energy receiving end, which powers the movement mechanism. After a user inputs an unlock command, the movement mechanism receives the command and drives the locking tongue to retract from the strike assembly, unlocking the door.
[0026] In yet another embodiment, an electric door locking device includes a strike assembly and a deadbolt assembly arranged around a door frame and a door having an opening on one side, and a user interface or electronic key for controlling the electric door locking device. The strike assembly includes a power source for supplying electricity to electrode 1 or the energy transmitting end. Electrode 1 or the energy transmitting end supplies power to electrode 2 or the energy receiving end. The deadbolt assembly includes a printed circuit board assembly (PCBA) in communication with electrode 2 or the energy receiving end via a conductive medium, and a movement mechanism in communication with the lock tongue. After the door is closed, the power source supplies electricity to electrode 1 or the strike electrode or the energy transmitting end, which supplies power to electrode 2 or the deadbolt electrode or the energy receiving end, and the PCBA powers the movement mechanism. After a command is input to the user interface or electronic key, the PCBA receives the command, and the movement mechanism moves, driving the lock tongue to retract and unlocking the door.

DETAILED DESCRIPTION OF THE INVENTION
[0029]
[0023] The following detailed description will be given of the embodiments of the present disclosure. Examples of the embodiments are shown in the accompanying drawings, and the same or similar reference numerals denote the same or similar elements, or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and are used only to explain the present disclosure, and should not be understood as limiting the present disclosure.
[0030] In describing the present disclosure, it should be understood that the directions or positional relationships included in descriptions of directions such as up, down, front, back, left, right, proximal, and distal are based on the directions or positional relationships shown in the drawings, and do not suggest or imply that the devices or elements referred to have a particular orientation or must be constructed and operated in a particular orientation, but are merely for convenience and simplicity of description of the present disclosure, and therefore should not be understood as limitations of the present disclosure.
[0031] Referring to FIG. 1, one embodiment of the present disclosure is shown. An electronic locking device and lock are shown, including a strike assembly 1 and a lock body 2. An electronic key 27 may be used to activate the electronic locking device. The electronic key may include, but is not limited to, a fingerprint, a retinal scan, a biometric reader, a wireless token, a password, a user interface, or the like. For example, a doorbell may be used as the user interface. Alternatively, a keypad not attached to the door may be used. Similarly, the system may be wireless and controlled solely by a cell phone, tablet, or other personal device assistant.
[0032] Strike plate assembly 1 includes a strike plate having an opening and a power module. In some embodiments, the power module may be an electrical module or an electromagnetic module as described herein. Lock body 2 includes lock tongue 6 and may also include a secondary latch. The lock tongue engages an opening 36 in the strike plate to lock the door. A proximal portion 25 of the secondary latch also helps maintain the door locked. As shown in FIG. 1 and the accompanying figures, for the aforementioned advantages, all electronic components, power sources, and / or wiring are routed through the door frame on the strike plate side of the door frame.
[0033] FIG. 2 shows the lock body 2 without the top cover to reveal the internal mechanical components. FIG. 2 also illustrates one embodiment of the present disclosure. The strike assembly 2 shows an electrical module 4 and an extension block 3. The module 4 may include, but is not limited to, an electric motor, an electromagnet, a dashpot, an electromechanical piston, and the like. The module 4 includes an extension block 3 that moves linearly back and forth when the module 4 is activated and deactivated by an electronic key 27. The strike assembly also includes a strike plate 5 having openings that receive the lock tongue 6 and the proximal end 25 of the auxiliary latch 7.
[0034] In some embodiments, lock body 2 may further include a secondary latch 7 having a proximal end 25 and a distal end 23. Secondary latch 7 may further include a secondary latch spring 8 secured in place by a positioning lug 9. Positioning lug 9 provides resistance to spring 8 such that a stretched spring 8 retracts distal portion 23 away from cam 10, allowing the cam to rotate. Spring 8 stretches as extension block 3 retracts into electrical module 4.
[0035] 3, when the expansion block 3 expands, the spring 8 is compressed against the positioning piece 9 and the distal portion 23 of the auxiliary latch engages the cam 10, preventing the cam from rotating and thus locking the door. The link strip 11 communicates with the cam 10 to lock the lock tongue 6 in the opening in the strike plate 5 which keeps the door locked.
[0036] The lock tongue 6 is part of the lock tongue body 19. A lock tongue spring 20 is disposed on the lock tongue body. A lock tongue positioning piece 21 provides resistance to the spring 20. When the spring 20 expands, the lock tongue 6 engages with the opening 36 in the strike plate 5, locking the door. When the spring 5 is compressed, the lock tongue retracts, allowing the door to be opened.
[0037] In some embodiments, the locking tongue body may also include a locking tongue cap 22. The locking cap 22 and the locking tongue positioning piece 21 provide resistance to a link 11 that may be disposed between them, allowing the link 11 to move the locking tongue 6.
[0038] Referring to FIG. 4, the operation of one embodiment of a locking device utilizing an electrical module 4 and an extension block 3 is illustrated. As shown, a spring 8 biases the auxiliary latch to push the extension block 7 into the electrical module 4. Movement of the extension block to open the door is initiated by an electric key 27. After activation, the distal portion 23 of the auxiliary latch retracts from the groove 17 of the cam 10. Depending on the implementation, the cam 10 may have multiple protrusions 16 that rotate with the cam in a circular path that drives the link strip 11. The cam 10 may also include a hole 15 in the center of the cam to receive a door handle shaft that rotates the cam when the cam is unlocked, as shown in FIG. 4.
[0039] 4 further shows the lock tongue mechanism 18, including the lock tongue 6, spring 20, locating piece 21, and lock tongue cap 22. When the cam 10 is free to rotate because the distal portion 23 is retracted from the groove 17, the cam rotation drives the link strip 11, which retracts the lock tongue 6. The spring 20 holds the lock tongue in the strike plate hole until the cam rotates and the pivoting force of the cam overcomes the strength of the spring, retracting the lock tongue and opening the door. When the cam stops rotating and the force is released from the door handle shaft, the spring 20 moves the lock tongue back into the strike plate hole.
[0040] FIG. 5 illustrates the locking or closing function of an embodiment of the electrical module and extension block. After the door is closed, extension of the extension block occurs. The secondary latch compresses the secondary latch spring. The secondary latch may have a bend so that the bend contacts the secondary latch spring at one end, causing the secondary spring to contact the positioning piece. The distal end of the secondary latch protrudes into the groove of the cam to lock the cam. The locked cam prevents the cam from rotating, maintaining the locked door closed.
[0041] Figure 6 further illustrates the unlocking principle of the electrical module and auxiliary latch mechanical system. After entering the electronic key, the electrical module drives the extension block to retract. The auxiliary latch spring again fully extends the auxiliary latch. The distal end of the auxiliary latch disengages from the cam groove. The cam is free to rotate, driving the link strip to move. The link strip again drives the lock tongue to retract, allowing the door to be released and unlocked.
[0042] 7 shows another embodiment utilizing an electromagnetic module 12 and a blocking block 14. Depending on the implementation, the blocking block may have a spring 13 disposed thereon and in contact with the locating point 9. The extension of the spring 13 drives a distal portion 24 of the blocking block to engage the cam groove 10 and lock the cam, preventing it from rotating and thereby locking the door. After the door is closed, the distal end 24 of the blocking block protrudes into the cam groove, locking the cam and maintaining the closed lock.
[0043] Figure 8 shows the unlocking of the locking device in the embodiment of Figure 7. After entering the electronic key, the electromagnetic module generates a magnetic field, which pulls the proximal end 26 of the blocking block toward the electromagnetic module 12. The distal end 24 disengages from the cam groove. This disengagement allows the cam to rotate freely as the door handle shaft rotates. The rotation of the cam drives the link strip to move, which in turn drives the lock tongue to retract from the strike plate opening, unlocking the door.
[0044] 9A and 9B show how an electronic locking device unlocks after receiving a signal from an electronic key. The cam moves horizontally. In some embodiments, the cam may move in any direction and in any manner. After receiving a signal from an electronic key 27, such as, but not limited to, a fingerprint or password, the electronic module 4 retracts the extension block 3, and the auxiliary latch spring 8 fully extends. The auxiliary latch protrusion 54 disengages from the blocking plate 51, and the blocking leaf spring 52 allows the blocking plate 51 to disengage from the cam groove. A limiting plate 53 is used to guide the limiting plate protrusion 55, which is part of the blocking plate 51, into the cam groove. The limiting plate also provides resistance to the blocking leaf spring, limiting the movement of the limiting plate protrusion into the cam groove. In some embodiments, the cam can move horizontally or in any direction due to the operation of the door handle, pushing the link strip 11 and causing the link strip to retract the lock tongue 6 into the locking device, unlocking the door.
[0045] 10A and 10B show how the electronic locking device unlocks after receiving a signal from the electronic key 27. The electric module 4 or electromagnetic module 12 retracts the extension block, causing the secondary latch spring to fully extend the secondary latch. The secondary latch disengages from the cam groove. The cam can move vertically due to the action from the door handle and push the link strip. The link strip then retracts the lock tongue into the lock, unlocking the door.
[0046] Fig. 11 is an embodiment of a deadbolt lock solution. As shown in Fig. 11, it is an exploded view of a strike assembly 28 of Solution 1 and a deadbolt 29 of Solution 1. The strike assembly 28 having a strike is provided with an opening 36.
[0047] Figures 12A-12D show cross-sectional views of the deadbolt lock shown in Figure 11. Figures 12A and 12B are enlarged views of portions of Figures 12C and 12D, respectively. The strike assembly 28 and deadbolt 29 of Solution 1 shown in Figures 12A-12D include a lock tongue 6, a strike 5, an electromagnetic module 14, a positioning piece 9, a blocking block spring 13, a blocking block 14, and a cam 10. In the locked position, after the door is closed, the end of the blocking block protrudes into the cam groove to prevent the cam from moving and maintain the lock closed. After entering an electronic key such as a fingerprint or password to unlock the deadbolt, the electromagnetic module generates a magnetic force to move the blocking block out of the cam groove. The cam is then free to move. The user can move the cam with the door handle, which drives the lock tongue to retract, unlocking the door.
[0048] Figure 13 shows Solution 2, or an embodiment different from the embodiment shown in Figure 11. Shown is a strike assembly 30 of Solution 2 and a deadbolt 31 of Solution 2. The strike assembly 30 has a strike and an opening 36.
[0049] Figures 14A-14B show the locked position for the embodiment shown in Figure 13. Figure 14A is an enlarged view of a portion of Figure 14B. A cross-sectional view of the strike assembly 30 and deadbolt 31 is shown, including the electrical module 4, locking tongue 6, extension block 3, telescoping rod 56, strike 5, and cam 10. To lock the system, the door handle is moved, and then the handle moves the cam, which in turn moves and extends the locking tongue, locking the door.
[0050] Figures 15A-15B show the unlocked position for the embodiment shown in Solution 2 of Figure 13. Figure 15A is an enlarged view of a portion of Figure 15B. After inputting the electronic key as described above, the electrical module drives the extension block to extend, which drives the telescopic rod to move, which drives the cam to move. The cam drives the lock tongue to retract, and then the door is unlocked.
[0051] Figure 16 shows Solution 3, or an embodiment different from the embodiment shown in Figure 11. Shown is a strike assembly 32 of Solution 3 and a deadbolt 33 of Solution 3. The strike assembly 32 has an opening 36 for receiving a locking tongue 6. The locking tongue 6 is moved by a moving mechanism 37, as will be further described herein.
[0052] Figures 17A-17C show the locked position for the embodiment shown in Figure 16. Figures 17A and 17C are enlarged views of a portion of Figure 17B. Figure 17B shows a cross-sectional view of the power supply cable 40, strike assembly 32, strike module 60, lock tongue 6, deadbolt electrode 58, lock tongue sleeve 59, printed circuit board assembly (PCBA) 41 that may be included in the movement mechanism, motor gearbox 42, cam 43, cam gear 44, cover plate 45, and motor gearbox gear 46, strike assembly 32, and deadbolt 33. To lock this system, after the door is closed, the power supply cable supplies electricity to the strike electrode 57. The strike electrode 57 may be the strike itself or may have an electrode built into the strike. The strike electrode supplies power to the deadbolt electrode 58. The deadbolt electrode then supplies power to the PCBA 41, which in turn supplies power to the motor gearbox 42.
[0053] In locking the above system in Solution 3, after a lock close command is input into a user interface, including but not limited to a mobile device, a keypad, a biometric interface, and any combination thereof, the PCBA receives the information and enables the motor gearbox gear to drive and move the cam gear. The cam gear rotates and drives and moves the lock tongue rod. The lock tongue rod drives and extends the lock tongue, and then the door is locked.
[0054] Figures 18A-18C show the unlocked positions for the embodiment shown in Solution 3 of Figure 16. Figures 18A and 18C are enlarged views of a portion of Figure 18B. As mentioned above, after inputting an unlock command or electronic key, the PCBA receives the information and enables the motor gearbox gear to drive and move the cam gear. The cam gear drives and moves the lock tongue rod, and the lock tongue rod drives the lock tongue to retract, and then the door is unlocked.
[0055] Figure 19 shows Solution 4, or an embodiment different from the embodiment shown in Figure 11. Shown is the Solution 4 strike assembly 34 and the Solution 4 deadbolt 35 with a movement mechanism 38, which will be described further herein.

The conductive medium may be any means of conducting electrical power, including, but not limited to, radio, radio frequency, conductive material, etc. After the door is closed, the power supply cable supplies electricity to electrode 1, which in turn supplies electricity to electrode 2. Electrode 2 supplies electricity to the PCBA via cable or conductive medium 39. The conductive medium may include, but is not limited to, an electrical cable, wire, conductive material, etc. The PCBA has a capacitor that can store electricity for the motor, which moves the motor gearbox, and then the deadbolt lock can lock and unlock.To lock this system, after giving the lock close command or electronic key, the PCBA receives the information and enables the gear of the motor gearbox to drive and move the cam gear.The cam gear drives and moves the cam, and the cam drives and extends the lock tongue, thus locking the door.
[0057] Figures 21A-21C show the unlocked position for the embodiment shown in Solution 4 of Figure 19. Figures 21A and 21C are enlarged views of a portion of Figure 21B. After issuing an unlock command or using an electronic key, PCBA 41 receives information, enabling motor gearbox gear 46 to reversely drive and reversely move cam gear 44. The cam gear drives and moves the cam, which drives lock tongue 6 to retract, and then the door is unlocked. In some embodiments, when the cam moves, the cam protrusion arm moves, which in turn moves lock tongue rod 56, which moves lock tongue 6.

[0060] 24-27B utilize all of the inventive subject matter described herein above with the addition of utilizing wireless charging to lock and unlock doors. Wireless charging may be contact-based or contactless, depending on the embodiment. The power supply may be either household AC or DC, such as a battery. In some embodiments, no external power supply is required, and the lock device may have a power storage capacity that can be wirelessly charged when the power storage capacity is low. Additionally, there may be a user interface that allows the user to determine when the power storage capacity is low. This interface may include, but is not limited to, a phone app, an electronic display on the lock device, and any combination thereof.
[0061] Wireless charging uses electromagnetic induction, also known as inductive coupling, to transfer energy between two objects, such as a charger and a smartphone. The charging base has a transmitting coil that sends out a signal, which seeks out a receiving coil, such as one found in a compatible smartphone. When the signal detects the receiving coil, electrons in the transmitting coil begin to flow around it. The transmitting coil emits an alternating current (AC) magnetic field, which induces an AC voltage / current in the receiving coil inside the device. Wireless charging can occur with or without contact. Contact means that the transmitting and receiving ends are in physical contact. Contactless means that the transmitting and receiving ends are not in physical contact, and energy is transmitted via radio frequency, microwave, electromagnetic force, other forms of wireless energy transmission, or a combination thereof.
[0062] In this embodiment, shown in FIG. 24 , an embodiment of the wireless charging, either contact or non-contact, and movement mechanism of the assembled lock device is shown in the locked position. In the locked position, the lock tongue of the lock body 19 is shown retracted into the strike assembly 1. Power from the power supply cable 40 transmits electrical power to the energy transmission end 50. The energy transmission end 50 then transmits energy, either through contact or non-contact, to the energy receiving end 47. The energy receiving end 47 then transmits power to the movement mechanism 37 to lock and unlock or move the lock tongue and lock body. Additionally, in some embodiments, the wireless charging may include a power source for providing electricity to the strike electrode or energy transmission end 50 for the strike assembly. The strike electrode or energy transmission end may then have an opening on one side of the door frame for the lock tongue to move through. The deadbolt assembly may further include the deadbolt electrode or energy receiving end 47, the movement mechanism, and the lock tongue. After the door is closed, the power source provides electricity to a strike electrode or energy transmitting end that powers the deadbolt electrode, or to an energy receiving end that powers the movement mechanism to lock and unlock the door.
[0063] Figure 25 is a perspective view of an embodiment of a wireless charging (contact or contactless) and movement mechanism for the assembled device of Figure 24, but in the unlocked position. Also, power may be transferred by contact or contactless means, such as but not limited to radio frequency, microwave, electromagnetic force, etc., between the energy transmitting end and the energy receiving end. Alternatively, the locking device may be directly charged, either contact or contactless, without a power supply cable, with power stored within the locking device itself.
[0064] Figure 26 is a perspective view of wireless charging again, either contact or contactless, as previously described, but with movement mechanism 38 including PCBA 41 and conductive media 39. This embodiment of the assembled locking device shown in Figure 26 is shown in the locked position.
[0065] In this embodiment, shown in Figures 26-27B, an embodiment of the wireless charging, either contact or contactless, of the assembled locking device and movement mechanism is shown in the locked position. In the locked position, the lock tongue of the lock body 19 is shown retracted into the strike assembly 1. Power from the power supply cable 40 transfers electrical power to the energy transmission end 48. The energy transmission end 48 then transfers energy to the energy receiving end 49, either through contact or without contact. Depending on the implementation, a conductive medium may or may not be connected to the movement mechanism to transfer power to the movement mechanism.
[0066] The energy receiving end 49 transmits power to the movement mechanism 38 having the PCBA 41 to lock and unlock or move the lock tongue and lock body. Additionally, in some embodiments, the wireless charging may include a power source for supplying electricity to the strike electrode or energy transmitting end 48 for the strike assembly. The strike electrode or energy transmitting end 48 may then have an opening on one side of the door frame for the lock tongue to move through. The deadbolt assembly may further include the deadbolt electrode or energy receiving end 49, the movement mechanism 38, and the lock tongue. After the door is closed, the power source supplies electricity to the strike electrode or energy transmitting end that powers the deadbolt electrode or the energy receiving end that powers the movement mechanism, locking and unlocking the door.
[0067] 27A and 27B are perspective views of an embodiment of a wireless charging (contact or contactless) and movement mechanism for the assembled locking device of FIG. 26, with FIGS. 27A and 27B showing the unlocked position. As shown in FIGS. 26 and 27A-27B, energy transmitting end 48 transmits power to energy receiving end 49. This can be done with or without contact with the respective ends, as described in FIGS. 24-25. As with FIGS. 24-25, the locking device itself may be wirelessly charged, either contact or contactless, by having internal power storage (not shown) or by being stored in a capacitor or the like on PCBA 41.
