Description

Technical Field

[0001] This application relates to the field of smart lock technology, specifically to a smart lock. Background Technology

[0002] Smart locks differ from traditional mechanical locks; they are composite locks that combine security, convenience, and advanced technology.

[0003] In related technologies, the motor inside a smart lock is generally a backpack motor. The backpack motor drives the bolt to extend and retract through a transmission component to perform locking and unlocking actions. When the backpack motor or key drives the bolt to unlock, it is difficult to move the bolt to open the door when the door resistance is high. At the same time, the power consumption of the motor is relatively large. Furthermore, the related technologies use a double linkage structure for unlocking, which is more complex and poses a risk of jamming and being unable to unlock. Utility Model Content

[0004] In view of this, this application provides a smart lock to solve or improve the problems of difficulty in opening the door when the door resistance is high and the door becoming stuck and unable to unlock.

The handle or the motor is used to drive the main bolt lever to rotate so as to drive the bolt to lock or unlock.

[0008] In this embodiment, with the latch locked, the motor drives the unlocking push plate to slide along a first direction. The unlocking push plate slides against the lever, and the unlocking push plate moves along the first direction, driving the lever to move, which in turn drives the main latch lever to rotate. The main latch lever causes the latch to retract, thus unlocking. Based on the lever principle, the unlocking push plate drives the lever to rotate, and the lever drives the main latch lever to rotate, making unlocking easier and solving or improving the problem of difficulty in opening the door when the door resistance is high. When the handle is rotated, the handle engages with the transmission gear through the locking push plate, driving the main latch lever to rotate. The main latch lever drives the latch to extend, thus locking. The dual unlocking and locking via the battery and handle prevents the latch from jamming and becoming unrecoverable.

[0033] Smart locks differ from traditional mechanical locks; they are composite locks that combine security, convenience, and advanced technology.

[0034] In related technologies, the motor in a smart lock is generally a backpack motor. The backpack motor drives the bolt to extend and retract via a transmission component to perform locking and unlocking actions. When the backpack motor or key drives the bolt to unlock, it is difficult to move the bolt to open the door when the door resistance is high. At the same time, the motor's power consumption is relatively high. Furthermore, the double-link structure used in related technologies is more complex and carries the risk of jamming and being unable to unlock. Therefore, this application provides a smart lock to solve or improve the problems of difficulty in opening the door when the door resistance is high and the risk of jamming and being unable to unlock.

[0035] The following is combined with Figures 1 to 2 This describes an embodiment of the present application.

[0036] According to an embodiment of this application, a smart lock is provided, including: a lock housing 1, a motor 2 and a bolt 3. The bolt 3 is slidably connected to the lock housing 1. A main bolt lever 4 is rotatably disposed inside the lock housing 1. A transmission tooth 401 is disposed on one side of the main bolt lever 4 and a lever 402 is disposed on the other side. The transmission tooth 401 is connected to the handle through meshing with the locking push plate 5. The main bolt lever 4 is connected to the bolt 3 in a transmission manner.

[0037] It also includes an unlocking push plate 6, which is slidably disposed on the lock housing 1 along the first direction X. The unlocking push plate 6 slides against the lever 402 and is used to push the lever 402 to rotate. The output end of the motor 2 can be connected to the locking push plate 5 and the unlocking push plate 6 for transmission. The handle or the motor 2 is used to drive the main lock tongue lever 4 to rotate so as to drive the lock tongue 3 to lock or unlock.

[0038] In this embodiment, such as Figure 2 As shown, with the latch 3 locked, the motor 2 drives the unlocking push plate 6 to slide along the first direction X. The unlocking push plate 6 slides against the lever 402, and the unlocking push plate 6 moves along the first direction X, driving the lever 402 to move, which in turn drives the main latch lever 4 to rotate. The main latch lever 4 drives the latch 3 to retract, thus unlocking. According to the lever principle, the unlocking push plate 6 drives the lever 402 to rotate, and the lever 402 drives the main latch lever 4 to rotate, making unlocking easier and solving or improving the problem of difficulty in opening the door when the door resistance is high. When the handle is rotated, the handle engages with the transmission gear 401 through the locking push plate 5, driving the main latch lever 4 to rotate. The main latch lever 4 drives the latch 3 to extend, thus locking. Through the dual unlocking and locking of the motor 2 and the handle, the latch 3 is prevented from jamming and becoming unable to unlock.

[0039] In some embodiments, such as Figure 2 As shown, the unlocking push plate 6 is an N-shaped plate, which includes a first vertical plate, a second vertical plate, and a horizontal plate. The first vertical plate, the horizontal plate, and the second vertical plate are connected end to end in sequence, and the first vertical plate and the second vertical plate are both arranged perpendicular to the horizontal plate. The surface of the horizontal plate slides against the lever 402.

[0040] Specifically, motor 2 can be a backpack motor.

[0041] In one embodiment, the motor 2 is connected to the unlocking push plate 6. The unlocking push plate 6 is provided with a first abutment part 601. The lever 402 slides against the first abutment part 601. The first abutment part 601 drives the main locking tongue pawl 4 to rotate through the lever 402 to drive the locking tongue 3 to unlock.

[0042] In this embodiment, such as Figure 2 As shown, the motor 2 drives the unlocking push plate 6 to move upward along the first direction X, the first abutment part 601 pushes the lever 402 to rotate clockwise, thereby driving the main lock tongue lever 4 to rotate clockwise, and then driving the lock tongue 3 to move to the right along the second direction Y, so that the lock tongue 3 retracts into the lock case 1 to unlock.

[0043] In one embodiment, the unlocking push plate 6 is provided with a step, which is the first abutment part 601.

[0044] In this embodiment, such as Figure 1 and Figure 2As shown, the first vertical plate and the horizontal plate form a step, and the first abutting part 601 is the surface of the horizontal plate. The first abutting part 601 can increase the contact area with the lever 402 and improve the stability of the sliding abutment.

[0045] In one embodiment, such as Figure 2 As shown, the end of the lever 402 that slides against the first abutment 601 is set as an arc end 4021.

[0046] In this embodiment, such as Figure 2 As shown, one end of the lever 402 is set as an arc end 4021, which can reduce the sliding friction between it and the first abutment part 601. The first abutment part 601 drives the lever 402 to rotate. During the rotation, the contact area between the lever 402 and the first abutment part 601 remains unchanged, which improves the stability of the lever 402 driving the main locking tongue 4 to rotate.

[0047] In one embodiment, such as Figure 2 As shown, the unlocking push plate 6 is provided with a guide part 7, which is slidably connected to the lock housing 1 along the first direction X.

[0048] In this embodiment, such as Figure 2 As shown, the guide portion 7 guides the unlocking push plate 6 to slide along the first direction X. The unlocking push plate 6 is adapted to slide and switch between a first position and a second position. In the first position, the first abutment portion 601 abuts against the lever 402, and the bolt 3 extends out of the lock housing 1 to lock. The first abutment portion 601 drives the lever 402 to rotate, so that the unlocking push plate 6 is in the second position. At the same time, the lever 402 drives the main bolt lever 4 to rotate, and the main bolt lever 4 drives the bolt 3 to retract, thereby unlocking.

[0049] In one embodiment, such as Figure 2 As shown, the guide section 7 includes:

[0050] Guide hole 701 is provided on unlocking push plate 6 and extends along the first direction X.

[0051] Guide block 702 is adapted to be connected to lock housing 1, and guide hole 701 is slidably connected to guide block 702.

[0052] In this embodiment, such as Figure 2 As shown, the inner wall of the guide hole 701 slides against the outer wall of the guide block 702, which can restrict the unlocking push plate 6 from sliding along the first direction X.

[0053] Specifically, the two side walls of the guide block 702 are arranged in parallel, and the two side walls of the guide block 702 slide against the two inner walls of the guide hole 701.

[0054] In some embodiments, such as Figure 2 As shown, both the first vertical plate and the second vertical plate are provided with guide holes 701, and the guide holes 701 on the first vertical plate and the second vertical plate extend along the first direction X. Two guide blocks 702 are provided, one end of each guide block 702 passes through the two guide holes 701 respectively, and the two guide blocks 702 slide against the inner wall of the two guide holes 701 respectively, which can prevent the first vertical plate and the second vertical plate from sliding along the second direction Y.

[0055] Specifically, the guide hole 701 is an oval hole, and the guide block 702 can be a cylinder, a block, or a plate.

[0056] In one embodiment, such as Figure 2 As shown, the main locking tongue lever 4 includes:

[0057] Mounting plate 403 is provided with mounting holes. The first end of lever 402 is connected to the side wall of mounting plate 403, and the second end of lever 402 slides against the first abutting part 601. Mounting plate 403 is connected to locking tongue 3 through transmission assembly 8. Transmission teeth 401 are provided on the side wall of mounting plate 403.

[0058] A connecting shaft 404 is provided, one end of which passes through the mounting hole and is connected to the lock housing 1. The connecting shaft 404 is rotatably connected to the mounting plate 403.

[0059] In this embodiment, such as Figure 2 As shown, when the latch 3 is locked, the motor 2 drives the unlocking push plate 6 to slide along the first direction X. The first abutment part 601 drives the mounting plate 403 to rotate through the lever 402, causing the mounting plate 403 to rotate. The mounting plate 403 drives the latch 8 to retract through the transmission assembly 8 to unlock.

[0060] In some embodiments, the connecting shaft 404 can be a screw or bolt to mount the mounting plate 403 onto the lock housing 1.

[0061] In one embodiment, such as Figure 2 As shown, the transmission assembly 8 includes:

[0062] Transmission rod 801, one end of which is connected to the side wall of mounting plate 403;

[0063] The latch connecting plate 802 is slidably connected to the lock housing 1 along the second direction Y. The latch connecting plate 802 is provided with a connecting hole 804 and is suitable for installing the latch 3.

[0064] A connecting rod 803 is provided, one end of which is connected to the transmission rod 801, and the other end passes through the connecting hole 804. A movable gap is provided between the connecting rod 803 and the connecting hole 804.

[0065] In this context, the first direction X is perpendicular to the second direction Y.

[0066] In one embodiment, such as Figure 1 As shown, the unlocking push plate 6 is provided with a second abutment part, and the end of the transmission rod 801 away from the mounting plate 403 can abut against the second abutment part.

[0067] In one embodiment, such as Figure 1 and Figure 2 As shown, motor 2 is mounted on lock housing 1, and a lever 9 is provided on the output end of motor 2. The lever 9 can be connected to the unlocking push plate 6 or the locking push plate 5.

[0068] In one embodiment, such as Figure 1 and Figure 2 As shown, it also includes: rack 10, rack 10 is connected to upper locking push plate 5, and multiple transmission teeth 401 are connected to rack 10 for transmission.

[0069] In this embodiment, such as Figure 1 As shown, the latch connecting plate 802 is slidably connected to the lock housing 1 along the second direction Y, and can slide between the extended position and the retracted position. When the latch 3 is locked, the motor 2 drives the unlocking push plate 6 to slide upward along the first direction X. The first abutting part 601 drives the mounting plate 403 to rotate clockwise through the lever 402. The mounting plate 403 drives the transmission rod 801 to rotate. The transmission rod 801 drives the latch connecting plate 802 to move from the extended position to the retracted position, that is, to the right along the second direction Y. The latch connecting plate 802 drives the latch 3 to retract, thus unlocking.

[0070] A movable gap is provided between the connecting rod 803 and the connecting hole 804 to ensure that when the transmission rod 801 performs circular motion to drive the locking tongue connecting plate 802 to perform linear motion in the second direction Y, no jamming occurs.

[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, a slider is provided on the latch connecting plate 802, and a guide groove 11 is provided on the lock housing 1. The guide groove 11 extends along the second direction Y, and the slider is slidably connected in the guide groove 11. A sliding hole 12 is provided on the latch connecting plate 802. The sliding hole 12 extends along the second direction Y, and a fixed shaft 13 is connected to the lock housing 1. The fixed shaft 13 passes through the sliding hole 12 and is slidably connected to the sliding hole 12 to limit the sliding distance of the latch connecting plate 802 along the second direction Y.

[0072] In some embodiments, such as Figure 1 and Figure 2As shown, a paddle 9 is mounted on the output shaft of motor 2. The output shaft of motor 2 drives the paddle 9 to rotate, and the paddle 9 can abut against the unlocking push plate 6, driving the unlocking push plate 6 to move upward along the first direction X. The first abutment part 601 drives the lever 402 to rotate, causing the mounting plate 403 to rotate clockwise. The mounting plate 403 drives the transmission rod 801 to rotate. The transmission rod 801 drives the lock tongue connecting plate 802 to slide to the right along the second direction Y through the connecting rod 803, moving from the extended position to the retracted position. The lock tongue connecting plate 802 drives the lock tongue 3 to retract, thus unlocking.

[0073] In some embodiments, such as Figure 1 and Figure 2 As shown, when motor 2 rotates, the paddle 9 drives the locking push plate 5 to slide upward along the first direction X. The rack 10 is connected to multiple transmission teeth 401, driving the mounting plate 403 to rotate counterclockwise. The mounting plate 403 drives the transmission rod 801 to rotate. The transmission rod 801 drives the lock tongue connecting plate 802 to slide to the left along the second direction Y through the connecting rod 803, moving from the retracted position to the extended position. The lock tongue connecting plate 802 drives the lock tongue 3 to extend, thus locking.

[0074] In some embodiments, such as Figure 1 and Figure 2 As shown, a handle transmission plate is also provided. The handle transmission plate is rotatably connected to the lock housing 1. One end of the handle transmission plate is connected to the locking push plate 5. The handle transmission plate is connected to the handle. The handle can drive the handle transmission plate to rotate. During the rotation, the handle transmission plate can drive the locking push plate 5 to move along the first direction X. Then, through the rack 10, it meshes with the drive teeth to drive the mounting plate 403 to rotate counterclockwise or clockwise. Then, the handle can be used to lock and unlock.

[0075] The following is an example, combined with Figures 1 to 2 A comprehensive explanation of all the above-mentioned plans is provided.

[0076] When motor 2 rotates, it drives lever 9 to rotate. Lever 9 drives locking push plate 5 to move upward along the first direction X. Rack 10 is connected to multiple transmission teeth 401, driving mounting plate 403 to rotate counterclockwise. Mounting plate 403 drives transmission rod 801 to rotate counterclockwise. Transmission rod 801 is connected to latch connecting plate 802 via connecting rod 803. Connecting rod 803 drives latch connecting plate 802 to move to the left along the second direction Y. Latch connecting plate 802 is equipped with latch 3, which can be driven to extend out of lock case 1 for locking. At the same time, lever 402 drives unlocking push plate 6 to move downward along the first direction X, driving unlocking push plate 6 to the locked position.

[0077] Motor 2 reverses direction, causing the lever 9 to rotate. The lever 9 drives the second vertical plate to move upward along the first direction X. The first abutment part 601 drives the lever 402 to rotate clockwise. The lever 402 drives the mounting plate 403 to rotate clockwise. The mounting plate 403 drives the transmission rod 801 to rotate clockwise. The transmission rod 801 drives the latch connecting plate 802 to move to the right along the second direction Y through the connecting rod 803. The latch 3 is installed on the latch connecting plate 802, which can drive the latch 3 to retract into the lock housing 1 to perform the unlocking action. At the same time, the transmission gear 401 drives the locking push plate 5 to move downward along the first direction X. At this time, the unlocking push plate 6 is in the unlocked position.

[0078] When the handle is turned, the handle transmission plate can drive the locking push plate 5 to move along the first direction X, and then through the rack 10, it meshes with the drive teeth to drive the mounting plate 403 to rotate counterclockwise or clockwise, thereby locking and unlocking through the handle.

[0079] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended application.
