Technical Field

[0001] This utility model relates to the field of cabinet locks, and in particular to an ultra-thin motor lock. Background Technology

[0002] The locks used in existing smart cabinets generally use electromagnets to open and close the door and reed switches to detect whether the door is closed. Currently, these locks cannot be unlocked in an emergency, and the large size of the reed switches makes the overall size of the lock large. In addition, the reed switches are also relatively easy to damage.

[0003] In view of the above problems, it is necessary to study an ultra-thin motor lock, which has the advantages of small size and emergency unlocking capability. Utility Model Content

[0004] The purpose of this utility model is to provide an ultra-thin motor lock, which has the advantages of small size and emergency unlocking capability.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] An ultra-thin motor lock includes a lock housing, a latch, a torsion spring, a motor unlocking assembly, a Hall element, and a control circuit board. The lock housing has a latch inlet / outlet and an emergency opening communicating with the inner cavity of the lock housing. The latch is rotatably disposed within the lock housing and has a locking part, an electronic unlocking part, and an emergency unlocking part. The torsion spring is disposed between the latch and the lock housing and is used to drive the latch to reset to the locked position. The motor unlocking assembly includes an unlocking block and a motor that drives the unlocking block to move. The unlocking block movably pushes against the electronic unlocking part of the latch, and the motor is fixed inside the lock housing. The Hall element is fixed inside the lock housing and is adjacent to the latch inlet / outlet. The control circuit board is fixed inside the lock housing and is electrically connected to the motor and the Hall element respectively. When the ultra-thin motor lock is in the locked state, the latch is in the locked position and the emergency unlocking part of the latch is movably opposite to the emergency opening, and the unlocking block of the motor unlocking assembly disengages from the electronic unlocking part of the latch.

[0007] The latch has a rotating shaft that is rotatably connected to the lock housing. A torsion spring is sleeved on the rotating shaft. The first end of the torsion spring abuts against the upper locking part of the latch, and the second end of the torsion spring abuts against the lock housing.

[0008] The upper locking part of the latch is provided with a groove for the first end of the torsion spring to fit into, and the lock housing is provided with a stop part for the second end of the torsion spring to abut against.

[0009] The motor unlocking assembly also includes a lead screw, the output shaft of the motor is connected to the lead screw, the unlocking block is screwed to the lead screw and the unlocking block is slidably connected to the lock housing.

[0010] The lock housing is provided with a sliding groove that slides into the unlocking block.

[0011] The output shaft of the motor is connected to the lead screw via a reducer.

[0012] The upper locking part of the latch is provided with a hook for engaging the lock hook.

[0013] The control circuit board and the motor are arranged vertically adjacent to each other, and the latch is located on the side of the control circuit board.

[0014] The lock case comprises two connected half-shells.

[0015] The lock housing has a through locking channel.

[0016] With the above solution, when the ultra-thin motor lock of this invention needs to be unlocked in an emergency while locked, the user can insert a tool (such as a screwdriver, push rod, etc.) into the emergency opening of the lock case, and use the tool to push against the emergency unlocking part of the latch, causing the latch to rotate to the unlocked position, thus disengaging the locking part of the latch from the lock hook and unlocking it, thereby achieving emergency unlocking. Furthermore, this invention replaces the existing reed switch with a Hall element. Compared to a reed switch, the Hall element is smaller and more reliable, effectively reducing the size of the ultra-thin motor lock and improving its reliability. Attached Figure Description

[0030] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0031] like Figures 1 to 3 As shown, this utility model discloses an ultra-thin motor lock A, which includes a lock housing 1, a latch 2, a torsion spring 3, a motor unlocking assembly 4, a Hall element 5, and a control circuit board 6; wherein, the lock housing 1 is provided with a hook inlet / outlet 11 communicating with the inner cavity of the lock housing 1 and an emergency opening 12; the latch 2 is rotatably disposed inside the lock housing 1, and the latch 2 has a locking part 21, an electronic unlocking part 22, and an emergency unlocking part 23, the locking part 21 is provided with a hook part 211 for hooking the latch B; the torsion spring 3 is disposed between the latch 2 and the lock housing 1, and the torsion spring 3 is used to drive the latch 2 to return to the locked position; the motor unlocking assembly 4 includes an unlocking part 4; The unlocking block 41 and the motor 42 that drives the unlocking block 41 to move, the unlocking block 41 actively pushes against the electronic unlocking part 22 of the latch 2, the motor 42 is fixed inside the lock housing 1; the Hall element 5 is fixed inside the lock housing 1 and is close to the lock hook inlet and outlet 11; the control circuit board 6 is fixed inside the lock housing 1 and is electrically connected to the motor 42 and the Hall element 5 respectively; when the ultra-thin motor lock A is in the locked state, the latch 2 is in the locked position and the emergency unlocking part 23 of the latch 2 is actively opposite to the emergency opening 12, and the unlocking block of the motor unlocking assembly 4 disengages from the electronic unlocking part 22 of the latch 2.

[0032] When using the ultra-thin motor lock A of this utility model, the ultra-thin motor lock A is installed on the cabinet, and the locking hook B that cooperates with the ultra-thin motor lock A is installed on the corresponding cabinet door. The locking hook B is equipped with a magnet C. When the ultra-thin motor lock A of this utility model is in the unlocked state, the unlocking block 41 pushes against the electronic unlocking part 22 of the latch 2, so that the latch 2 is in the unlocked position. At this time, the upper locking part 21 of the latch 2 is deviated from the locking hook inlet and outlet 11. When the user closes the cabinet door, the locking hook B is inserted into the locking hook inlet and outlet 11 of the latch 2. At this time, the Hall element 5 senses the magnet C and sends a signal to the control circuit board 6. The control circuit board 6 controls the motor 42 to drive the unlocking block 41. The electronic unlocking part 22 of the latch 2 is disengaged and the latch 2 rotates to the locked position under the action of the torsion spring 3, so that the locking part 21 of the latch 2 hooks the hook B (the locking part 21 is opposite to the hook inlet / outlet 11), and at this time the emergency unlocking part 23 of the latch 2 moves opposite to the emergency opening 12. When the user wants to unlock, the user sends an unlocking command to the control circuit board 6, and the control circuit board 6 controls the motor 42 to drive the unlocking block 41 to move and abut against the electronic unlocking part 22 of the latch 2, so that the latch 2 rotates to the unlocking position. At this time, the locking part 21 of the latch 2 disengages from the hook B and is unlocked (the locking part 21 of the latch 2 deviates from the hook inlet / outlet 11).

[0033] When the ultra-thin motor lock A of this invention needs to be unlocked in an emergency while locked, the user can insert a tool (such as a screwdriver, push rod, etc.) into the emergency opening 12 of the lock housing 1, and the tool will push against the emergency unlocking part 23 of the latch 2, causing the latch 2 to rotate to the unlocked position, so that the locking part 21 of the latch 2 disengages from the lock hook B and is unlocked, thereby achieving emergency unlocking. The tool can be inserted into the emergency opening 12 of the lock housing 1 through an opening reserved in the cabinet, and the cabinet opening can be opened and closed by a mechanical lock. Furthermore, this invention replaces the existing reed switch with a Hall element 5. Compared with the reed switch, the Hall element 5 is smaller and more reliable, which effectively reduces the size of the ultra-thin motor lock A of this invention and improves its reliability.

[0034] In an embodiment of this utility model, the latch 2 has a rotating shaft that is rotatably connected to the lock housing 1, and a torsion spring 3 is sleeved on the rotating shaft.

The lock housing 1 may be provided with abutting part 14 for the second end of the torsion spring 3 to abut against.

[0035] In an embodiment of this utility model, the motor unlocking assembly 4 further includes a lead screw 43, the output shaft of the motor 42 is connected to the lead screw 43, the unlocking block 41 is screwed to the lead screw 43 and slidably connected to the lock housing 1; when the motor 42 drives the lead screw 43 to rotate, the lead screw 43 drives the unlocking block 41 to translate; wherein, the lock housing 1 is provided with a sliding groove 15 that slides with the unlocking block 41 so that the unlocking block 41 translates smoothly; and the output shaft of the motor 42 can be connected to the lead screw 43 through a reducer 44, so that the motor 42 can be a small torque, low cost micro motor.

[0036] In an embodiment of this utility model, the control circuit board 6 and the motor unlocking component 4 are arranged adjacent to each other vertically, and the latch 2 is located on the side of the control circuit board 6; this can effectively utilize the internal space of the lock housing 1, making the ultra-thin motor lock A of this utility model small in size.

[0037] In an embodiment of this utility model, the lock housing 1 includes two connected half-shells 101, which facilitates the installation of the lock housing 1, the latch 2, the torsion spring 3, the motor unlocking assembly 4, the Hall element 5, and the control circuit board 6. The lock housing 1 may be provided with a through locking channel 13 so that the lock housing 1 can be locked to the cabinet by screws passing through the locking channel 13.
