[0032] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] Reference Figure 1-2This utility model provides a motor lock, including a bottom shell 1, a front cover 2, a motor 3, a stop block 4, a movable block 5, and a U-shaped component 6. The bottom shell 1 and the front cover 2 can be combined to form a shell with an inner cavity. The motor 3, the stop block 4, the movable block 5, and the U-shaped component 6 are all disposed in the inner cavity. The U-shaped component 6 can be used to engage with an external latch 7 for locking. The stop block 4 can engage with the U-shaped component 6 to prevent the U-shaped component 6 from moving freely. The movable block 5 can engage with the stop block 4 to drive the stop block 4 to move. The motor 3 can be connected to the movable block 5 to drive the movable block 5 to move, thereby unlocking the motor lock.

[0034] The front cover 2 and the bottom shell 1 can be fastened together and fixed by bolts. Both the front cover 2 and the bottom shell 1 have a locking groove 13 on one side, which communicates with the inner cavity. The latch 7 can cooperate with the U-shaped piece 6 in the locking groove to lock the motor 3.

[0035] Reference Figure 2 The front cover 2 and the bottom shell 1 are respectively provided with a first sliding groove 11 and a second sliding groove 21. The first sliding groove 11 and the second sliding groove 21 can cooperate with the movable block 5 respectively, restricting the movement direction of the movable block 5, so that the sliding block can slide stably in the first sliding groove 11 and the second sliding groove 21.

[0036] Reference Figure 2 The middle part of the U-shaped component 6 is rotatably connected to the front cover 2 and the bottom shell 1, allowing the U-shaped component 6 to rotate within the inner cavity. One end of the U-shaped component 6 is provided with a slot 61, which can communicate with the locking groove as the U-shaped component 6 rotates. When locking the door, the latch 7 can be located in the locking groove and engaged in the slot 61. The stop block 4 prevents the U-shaped component 6 from rotating, thereby preventing the latch 7 from disengaging from the U-shaped component 6, thus completing the locking process.

[0037] The end of the U-shaped part 6 away from the slot 61 has an inwardly recessed abutment surface 62, which can cooperate with the stop block 4 to prevent the rotation of the U-shaped part 6. An opening signal switch 12 is fixed on the bottom shell 1. A first protrusion 63 is provided on one side of the U-shaped part 6. The U-shaped part 6 can rotate until the first protrusion 63 contacts the spring plate of the opening signal switch 12, so that the opening signal switch 12 can send a signal to the motor 3 to drive the motor 3 to work.

[0038] Specifically, the U-shaped component 6 rotates in two states: a first state and a second state. In the first state, the U-shaped component 6 rotates to the point where the slot 61 and the locking slot are connected. In the second state, the first protrusion 63 contacts the spring plate of the door opening signal switch 12. A first torsion spring 64 is fixed to the U-shaped component 6, with one end fixed to the bottom shell 1 and the other end fixed to the U-shaped component 6. When the first torsion spring 64 is in operation, it can drive the U-shaped component 6 to rotate from the first state to the second state.

[0039] The stop block 4 is rotatably connected to the bottom shell 1 and the front cover 2 in the middle. The stop block 4 includes a front end 41 and a rear end 42 that are arranged opposite each other. The front end 41 is set towards the U-shaped piece 6, and the rear end 42 is set towards the movable block 5 and is fixed with the emergency rod 421. A second torsion spring 43 is fixed on the stop block 4. One end of the second torsion spring 43 is fixed to the bottom shell 1, and the other end is fixed to the stop block 4 or the emergency rod 421. The second torsion spring 43 can drive the stop block 4 and the emergency rod 421 to rotate counterclockwise.

[0040] In the first state, the abutment surface 62 of the U-shaped part 6 can abut against the end face of the front end 41, allowing the stop block 4 to stably hold the U-shaped part 6 in the first state. The emergency lever 421 can cooperate with the movable block 5, so that the movement of the movable block 5 can drive the stop block 4 to swing. When locking, the latch 7 pushes the U-shaped part 6 to rotate from a distance, lifting the front end 41 and rotating it to the first position. Under the action of the first torsion spring 64, the rebound of the U-shaped part 6 can make the end face of the front end 41 press against the abutment surface 62, so that the U-shaped part 6 can be locked by the stop block 4 and stabilized in the first state. The position of the latch 7 is restricted within the slot 61 to achieve locking.

[0041] Reference Figure 3 The movable block 5 is fixed with a first slider 51 and a second slider 52 on both sides near the front cover 2 and the bottom shell 1, respectively. The first slider 51 and the second slider 52 can slide and connect to the first slide groove 11 and the second slide groove 21, respectively, so that the movable block 5 can slide stably in the inner cavity.

[0042] The motor 3 is fixed to the base shell 1. A screw 31 is fixed to the end of the output shaft of the motor 3. The axial direction of the screw 31 is the same as the extension direction of the first slide groove 11 and the second slide groove 21. A threaded hole 53 is opened on the lower side of the movable block 5. The screw 31 is threaded into the threaded hole 53. When the motor 3 is working, it can drive the screw 31 to rotate, which in turn can drive the movable block 5 to slide.

[0043] Reference Figure 2 and Figure 4 The movable block 5 has a notch 54 on its surface away from the bottom shell 1. The notch 54 includes a bottom surface 543, a first end 541, and a second end 542. The first end 541 and the second end 542 are arranged opposite each other. The bottom surface 543 is perpendicular to and intersects the first end 541 and the second end 542. A threaded hole 53 communicates with the notch 54. A screw 31 is connected in the threaded hole 53, allowing one end of the movable block 5 to be connected to the motor 3 via the screw 31. The emergency rod 421 can be placed in the notch 54 and abut against the end face of the second end 542, so that the emergency rod 421 can be driven to rotate when the movable block 5 slides.

[0044] The movable block 5 of this application has a notch 54. When installing the electronic lock, the motor 3 and the movable block 5 can be installed onto the bottom shell 1 first, and then the stop block 4 with the emergency rod 421 can be installed. It is not necessary to insert the emergency rod 421 on the stop block 4 into the movable block 5, and then install the motor 3, the stop block 4 and the movable block 5 onto the bottom shell 1 simultaneously. This makes it easier for the assembly personnel to install and improves the assembly efficiency.

[0045] Reference Figure 2 and Figure 5 When the motor 3 is locked, under the action of the second torsion spring 43, the emergency lever 421 swings to abut against the end face of the emergency lever 421 and the second end 542. The movable block 5 can prevent the continued rotation of the movable block 5 and limit the position of the movable block 5. When unlocking, the motor 3 receives the unlocking signal and the motor 3 can drive the screw 31 to rotate, which in turn drives the movable block 5 to slide, causing the second end 542 to move down and press against the emergency lever 421. The emergency lever 421 drives the stop block 4 to rotate. The stop block 4 rotates clockwise, causing the abutment surface 62 to disengage from the end face restriction of the front end 41. Under the action of the first torsion spring 64, the U-shaped part 6 rotates from the first state to the second state, popping out the latch 7 to unlock.

[0046] A second protrusion 56 is fixed to one side of the movable block 5, and an unlocking signal switch 14 is also fixed in the bottom shell 1. As the movable block 5 slides down and presses down the emergency lever 421, the second protrusion can move to abut against the spring plate of the unlocking signal switch 14. The unlocking signal switch 14 and the door opening signal switch 12 can work together. When the first protrusion 63 triggers the door opening signal switch 12 or the second protrusion 56 triggers the unlocking signal switch 14, the motor 3 can stop rotating and then rotate in the opposite direction according to the time set by the circuit program. The movable block 5 returns to its original position under the action of the second torsion spring 43, ready to lock the lower side.

[0047] In one embodiment, two latching protrusions 15 are provided on both sides of the bottom shell 1, forming a clamping groove 16 between the two latching protrusions 15. A circuit board 17 is fixed between the clamping grooves on both sides of the bottom shell 1. The circuit board 17 is electrically connected to the motor 3, the door opening signal switch 12, and the lock unlocking signal switch 14. The circuit board 17 can receive external unlocking signals to control the motor 3 to start, and can also receive signals from the door opening signal switch 12 and the lock unlocking signal switch 14 to control the motor to reverse. It should be noted that the circuit of the circuit board 3 controlling the motor 3 to reverse according to time is a common existing technology in locks, and will not be described in detail in this application.

[0048] In one embodiment, a slot is provided at one end of the screw 31, and the output shaft of the motor 3 is inserted into the slot. The output shaft of the motor 3 and the screw 31 are fixed together by a fastening pin 32. The fastening pin 32 enables a stable connection between the screw 31 and the output shaft of the motor 3, and the fastening pin 32 is embedded in the screw without affecting other parts, thus avoiding interference.

[0049] As one embodiment, the bottom surface 543 of the movable block 5 corresponding to the notch 54 is provided with a relief groove 55, which allows the screw 31 to move into the space of the notch 54.

[0050] The implementation principle of this utility model is as follows: When locking, the latch 7 pushes the U-shaped part 6 to rotate from a distance, lifting the front end 41 and rotating it to the first state. Under the action of the first torsion spring 64, the U-shaped part 6 rebounds, allowing the end face of the front end 41 to press against the abutment surface 62, so that the U-shaped part 6 can be locked and stabilized in the first state by the stop block 4. The position of the latch 7 is restricted within the slot 61 to achieve locking. When unlocking, the motor 3 receives the unlocking signal, and the motor 3 works to drive the screw 31 to rotate, which in turn drives the movable block 5 to slide, causing the second end 542 to move down and press the emergency rod 421. The emergency rod 421 drives the stop block 4 to rotate, and the stop block 4 rotates clockwise, causing the abutment surface 62 to disengage from the end face restriction of the front end 41. Under the action of the first torsion spring 64, the U-shaped part 6 rotates from the first state to the second state, popping out the latch 7 to achieve unlocking.

[0051] The movable block 5 of this application has a notch 54. When installing the electronic lock, the motor 3 and the movable block 5 can be installed onto the bottom shell 1 first, and then the stop block 4 with the emergency rod 421 can be installed. It is not necessary to insert the emergency rod 421 on the stop block 4 into the movable block 5, and then install the motor 3, the stop block 4 and the movable block 5 onto the bottom shell 1 simultaneously. This makes it easier for the assembly personnel to install and improves the assembly efficiency.
