Description

Technical Field

[0001] This invention relates to the technical field of door locks, and in particular to an automatic charging smart door lock. Background Technology

[0002] Smart locks are improvements upon traditional mechanical locks, offering greater intelligence and convenience in terms of user security, identification, and management. As people become more security-conscious, they are increasingly inclined to use smart locks as the locking mechanism in access control systems.

[0003] Because smart locks require constant power, they typically contain rechargeable batteries. While smart locks consume little power, prolonged use can still cause the battery's charge to drop. Therefore, new types of self-charging smart locks have emerged. However, conventional smart locks have many components and auxiliary parts, making repairs and replacements more difficult and costly. Summary of the Invention

[0004] The main objective of this invention is to provide an automatically rechargeable smart door lock, thereby effectively solving the problems pointed out in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automatic charging smart door lock includes a door body with a door lock mechanism installed on it.

At the same time, numerals such as "first," "second," and "third" do not represent a specific quantity or order, but are only used to distinguish names. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0020] like Figures 1 to 7 As shown, an automatic charging smart door lock includes a door body 1, a door lock mechanism installed on the door body 1, and a mounting box 2 installed inside the fixing groove of the door body 1. A movable seat 3 is slidably installed inside the cavity of the mounting box 2. Multiple sets of positioning pins 4 are installed on the movable seat 3, and the multiple sets of positioning pins 4 are slidably connected to the through holes of the mounting box 2 respectively. Two sets of fixing plates 5 are provided inside the cavity of the mounting box 2. A first spring 6 is installed on the fixing plate 5, and the other end of the first spring 6 is connected to the movable seat 3. The positioning pins 4 are chamfered on the rotating and closing side of the door body 1. A drive mechanism installed inside the cavity of the mounting box 2 is used to drive the multiple sets of positioning pins 4 on the movable seat 3 to move. A control panel 7 is installed on the mounting box 2 and is connected to the drive mechanism. The control panel 7 has multiple functions including password, fingerprint and face recognition. During use, the door body 1 is installed in conjunction with the door frame through the door lock mechanism. Multiple sets of positioning pins 4 are slidably installed on the mounting box 2 through the movable seat 3. The positioning pins 4 have a chamfer on one side to limit the door body 1 and the door frame and allow unidirectional rotation. The multiple sets of positioning pins 4 increase the connection strength between the door body 1 and the door frame. The first spring 6 is stably supported inside the cavity of the mounting box 2 through the fixing plate 5. The movable seat 3 provides driving power to the positioning pins 4 through the cooperation of two sets of first springs 6. The driving mechanism causes the movable seat 3 to move the multiple sets of positioning pins 4 to disconnect the door body 1 from the door frame. The driving mechanism is controlled through the control panel 7, which improves the ease of use of the door lock.

[0021] As a preferred embodiment of the above, a movable frame 8 is slidably installed inside the cavity of the mounting box 2. Multiple sets of locking pins 9 are installed on the movable frame 8. The multiple sets of locking pins 9 are slidably connected with the inner hole of the mounting box 2. A sleeve 10 is installed on the movable seat 3. The sleeve 10 is in contact with the movable frame 8. During use, the moving frame 8 allows multiple sets of locking pins 9 to slide inside the cavity of the door body 1. The multiple sets of locking pins 9 cooperate with the door frame to increase the strength of the door body 1 and the door frame. The sleeve 10 allows the moving seat 3 to move, and the moving frame 8 drives the multiple sets of locking pins 9 to disengage from the door frame.

[0022] As a preferred embodiment of the above, the drive mechanism includes a connecting beam 11, which is mounted on the movable seat 3. Spur racks 12 are symmetrically installed in the fixing grooves at both ends of the connecting beam 11. Two sets of support shafts 13 are rotatably installed inside the cavity of the mounting box 2. A first gear 14 is coaxially mounted on the support shaft 13 and meshes with the spur rack 12 for transmission. A second gear 15 is coaxially mounted on the support shaft 13 and the two sets of second gears 15 mesh for transmission. During use, the two sets of racks 12 are symmetrically mounted on the movable seat 3 via the connecting beam 11. The first gear 14 is rotated and supported inside the cavity of the mounting box 2 via the support shaft 13. The first gear 14 meshes with the rack 12 to drive the support shaft 13 and the connecting beam 11. The two sets of second gears 15 mesh to drive the two sets of support shafts 13 synchronously in opposite directions. By setting two sets of support shafts 13, the transmission strength of the connecting beam 11 driving the movable seat 3 is increased.

[0023] As a preferred embodiment of the above embodiment, an installation shaft 16 is rotatably installed inside the cavity of the installation box 2, and a transmission component 17 is coaxially installed on the installation shaft 16. The outer wall of the transmission component 17 is composed of teeth, arc edges and straight edges. A connecting component 18 is coaxially installed on a set of support shafts 13. The connecting component 18 is provided with arc grooves, teeth and grooves. The teeth of the transmission component 17 and the teeth of the connecting component 18 mesh and are connected for transmission. The arc edges of the transmission component 17 and the arc grooves of the connecting component 18 are slidably connected. During use, the transmission component 17 rotates and is supported inside the cavity of the mounting box 2 via the mounting shaft 16. The teeth of the transmission component 17 mesh with the teeth of the connecting component 18, causing the mounting shaft 16 to drive the first gear 14 on the support shaft 13 to rotate and mesh with the rack 12. This causes the moving seat 3 to drive multiple sets of positioning pins 4 to disengage from the door frame. The mounting shaft 16 drives the arc edge of the transmission component 17 to engage with the arc groove of the connecting component 18, causing the support shaft 13 to rotate and lock, preventing the moving seat 3 from moving the positioning pins 4 and locking the door body 1 to the door frame. The transmission component 17 and the straight edge and the groove of the connecting component 18 disengage the transmission component 17 and the connecting component 18 from the moving seat 3. Two sets of first springs 6 work together to drive the positioning pins 4 to reset, facilitating subsequent engagement with the door frame.

[0024] As a preferred embodiment of the above, a servo motor 19 is provided inside the cavity of the mounting box 2. A third gear 20 is coaxially mounted on the output end of the servo motor 19. A fourth gear 21 is coaxially mounted on the mounting shaft 16. The fourth gear 21 and the third gear 20 are meshed and connected for transmission. The servo motor 19 is electrically connected to the control panel 7. During use, the servo motor 19 is connected to the mounting shaft 16 by the cooperation of the third gear 20 and the fourth gear 21. The servo motor 19 provides rotational power to the mounting shaft 16, and the control panel 7 controls the servo motor 19 to provide rotational power.

[0025] As a preferred embodiment of the above embodiment, a drive shaft 22 is rotatably mounted inside the cavity of the mounting box 2, a support beam 23 is rotatably mounted on the drive shaft 22, a ratchet is provided inside the support beam 23, a stop block 24 is rotatably mounted on the drive shaft 22, a second spring 25 is mounted on the stop block 24 and the support beam 23, the stop block 24 and the support beam 23 are connected by the ratchet, two sets of limiting posts 26 are installed inside the cavity of the mounting box 2, the two sets of limiting posts 26 are located on both sides of the support beam 23, and an adjusting cap 36 is coaxially mounted on the drive shaft 22; During use, the drive shaft 22 causes the support beam 23 to rotate and support it inside the cavity of the mounting box 2. The second spring 25 causes the stop block 24 to engage with the support beam 23 through ratchet engagement. The ratchet engagement between the stop block 24 and the support beam 23 enables unidirectional transmission between the drive shaft 22 and the support beam 23. The drive shaft 22 drives the support beam 23 to rotate and contact the moving frame 8, locking the working position of multiple sets of locking pins 9. The two sets of limit pins 26 work together to limit the rotation range of the support beam 23, further improving the working strength of the door lock mechanism.

[0026] As a preferred embodiment of the above, a positioning slide rail 27 is provided inside the cavity of the mounting box 2, and a transmission beam 28 is slidably mounted on the positioning slide rail 27. One end of the transmission beam 28 is in contact with and slidably connected to the support beam 23, and a third spring 29 is installed at the other end of the transmission beam 28. One end of the spring 29 is installed on the cavity wall of the mounting box 2.

[0027] During use, the transmission beam 28 is positioned and slidably supported inside the cavity of the mounting box 2 by the positioning slide rail 27. The third spring 29 moves the transmission beam 28 and provides reset power. The movement of the transmission beam 28 cooperates with the support beam 23 to release the support beam 23 from the support of the moving frame 8, which facilitates the subsequent movement of the moving frame 8 and multiple sets of locking pins 9 relative to the mounting box 2.

[0028] As a preferred embodiment of the above, the sector gear 30 is coaxially mounted on the mounting shaft 16, and a straight tooth is provided on one side of the transmission beam 28. The sector gear 30 and the transmission beam 28 are meshed and connected for transmission. During use, the mounting shaft 16 drives the sector gear 30 to rotate and engages with the spur teeth of the transmission beam 28, providing the transmission beam 28 with the power to move, which facilitates the rotation of the support beam 23 and increases the working stability of the device.

[0029] As a preferred embodiment of the above, a piston slider 31 is slidably installed in the connecting groove of the door body 1, a transmission column 32 is provided on the piston slider 31, the transmission column 32 is provided with a chamfer at the outer end of the connecting groove of the door body 1, a touch switch 33 is provided inside the connecting groove of the door body 1, the transmission column 32 is in contact with the touch switch 33, the touch switch 33 is electrically controlled by the servo motor 19, a fourth spring 34 is installed on the piston slider 31, and the other end of the fourth spring 34 is connected to the wall of the connecting groove of the door body 1. During use, the piston slider 31 causes the transmission column 32 to slide and connect with the door body 1. The fourth spring 34 causes the piston slider 31 to drive the transmission column 32. The transmission column 32 contacts the door frame, causing the door body 1 to open automatically. The transmission column 32 contacts the touch switch 33, causing the servo motor 19 to start. The mounting shaft 16 drives the transmission component 17 to rotate. The arc edge and the arc groove of the connecting component 18 are matched. At the same time, the door body 1 opens and rotates automatically, which is easier to open when both hands are holding objects, compared to the traditional manual opening method.

[0030] When the door 1 needs to close and engage with the door frame, multiple sets of positioning pins 4 are first compressed by the force applied to the two sets of first springs 6. When the driving force of the positioning pins 4 disappears, the multiple sets of positioning pins 4 are reset by the first springs 6 and engage with the door frame. During the engagement of the door 1 and the door frame, the transmission column 32 is compressed by the force applied to the fourth spring 34. After the door 1 engages with the door frame, the transmission column 32 contacts the touch switch 33. At this time, the touch switch 33 controls the servo motor 19 to start. Then, the servo motor 19 meshes with the third gear 20 and the fourth gear 21. The mounting shaft 16 rotates, which in turn drives the transmission component 17 to rotate until the arc plate of the transmission component 17 mates with the arc groove of the connecting component 18. At this point, the moving seat 3 and multiple sets of positioning pins 4 are locked to the mounting box 2. When the connection between the door body 1 and the door frame needs to be reinforced, the support beam 23 on the drive shaft 22 is rotated by adjusting the cap 36. Then, the support beam 23 and the moving frame 8 work together to move multiple sets of locking pins 9 to mate with the door frame. When the door body 1 needs to be opened, the servo motor 19 can be started via the control panel 7. When the servo motor 19 starts, it drives the mounting shaft 16 to rotate through the meshing of the third gear 20 and the fourth gear 21. The mounting shaft 16 drives the sector gear 30 to rotate and mesh with the transmission beam 28. Then, the transmission beam 28 drives the support beam 23 to rotate. At the same time, the mounting shaft 16 drives the transmission component 17 to rotate. First, the arc edge of the transmission component 17 disengages from the arc groove of the connecting component 18. Then, the teeth of the transmission component 17 engage with the teeth of the connecting component 18, and the support shaft 13 drives the first gear 14 to rotate. Then, the first gear 14 engages with the rack. 12 The engagement of the connecting beam 11 drives the multiple sets of positioning pins 4 on the moving seat 3 to disengage from the door frame. During this process, the sleeve 10 drives the moving frame 8 to move multiple sets of locking pins 9 synchronously. After the locking pins 9 and positioning pins 4 are disengaged from the door frame, the door body 1 flips under the force of the fourth spring 34 through the transmission column 32. After the teeth of the transmission component 17 and the teeth of the connecting component 18 disengage, the transmission component 17 and the connecting component 18 disengage. At this time, the moving seat 3 drives the multiple sets of positioning pins 4 to reset under the force of the first spring 6.

[0031] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
