Description

Technical Field

[0001] This utility model belongs to the field of lock cylinder technology, and specifically refers to a motor lock cylinder. Background Technology

[0002] Door locks are a staple in every household. Traditional door locks are all mechanical locks. With the advancement of technology, traditional mechanical locks have gradually been replaced by smart locks. Smart locks offer great convenience because they eliminate the need to carry cumbersome keys. However, the gearbox and lock cylinder within these smart locks need to be fixed together. Otherwise, the vibrations from repeated forceful opening and closing of the door can cause the lock cylinder and gearbox to shift and become loose, making it difficult for the motor to drive the lock cylinder to rotate or even preventing it from rotating at all, resulting in the motor spinning without being able to drive the lock cylinder to unlock. Currently, workers use a method of drilling holes and connecting the two together with screws. This method is too simplistic and limited. Therefore, a better method is needed that can connect and fix the lock cylinder and gearbox without affecting the normal opening and closing of the smart lock. Summary of the Invention

[0003] The purpose of this invention is to provide a motor lock cylinder with a simple structure that can connect and fix the lock cylinder to the gearbox without affecting the normal opening and closing of the smart lock.

[0004] The purpose of this utility model is achieved as follows:

[0005] A motor lock cylinder includes a geared motor and a lock cylinder. The lock cylinder contains a lock cylinder core. One end of the geared motor has a rotating shaft connected to the lock cylinder core. The geared motor can drive the lock cylinder core to rotate through the rotating shaft. The upper end of the lock cylinder also has a connecting part, and the lower end of the geared motor has a fixing part. The geared motor is fixedly connected to the connecting part on the lock cylinder through the fixing part. The connecting part has an internal thread, and the fixing part has an external thread. The geared motor is threadedly connected to the internal thread on the lock cylinder through the external thread.

[0006] Furthermore, the lower end of the geared motor is provided with an extension part, the external thread is provided on the extension part, the lock cylinder is provided with a lock cylinder hole, the internal thread is provided in the lock cylinder hole, and the extension part can extend into the lock cylinder hole and be fixedly connected to the lock cylinder.

[0007] Furthermore, a rotating component is provided between the geared motor and the lock cylinder. One end of the rotating component is connected to the rotating shaft, and the other end is connected to the lock cylinder core. In the working state, the rotating shaft drives the lock cylinder core to rotate through the rotating component.

[0008] Furthermore, the geared motor includes a drive motor and a gearbox. The drive motor is provided with a motor shaft, and the drive motor is connected to the gearbox through the motor shaft. The rotating shaft is located at the lower end of the gearbox.

[0009] Furthermore, the gearbox contains several layers of planetary gears and sun gears. The motor shaft meshes with the planetary gears at the top of the gearbox, driving the sun gear to rotate. The sun gear drives the planetary gears mounted on the next layer of support, forming a multi-stage rotating connection.

[0010] Furthermore, the lower end of the rotating shaft is a waist-shaped rod, and the rotating component has a waist-shaped hole that matches the waist-shaped hole.

[0011] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0012] This utility model relates to a motor-driven lock cylinder, comprising a geared motor and a lock cylinder. The lock cylinder contains a lock cylinder core. One end of the geared motor has a rotating shaft connected to the lock cylinder core. Driving the geared motor via the rotating shaft causes the lock cylinder core to rotate. The upper end of the lock cylinder also has a connecting part, and the lower end of the geared motor has a fixing part. The geared motor is fixedly connected to the connecting part on the lock cylinder via the fixing part. This utility model, by providing a connecting part on the lock cylinder and a fixing part at the lower end of the geared motor, connects and fixes the lock cylinder and the geared motor. At this point, the positions of the geared motor and the lock cylinder are fixed and cannot move. When the geared motor drives the lock cylinder core to rotate, the lock cylinder core will not rotate synchronously with the lock cylinder. Once the lock cylinder and geared motor are fixed together by the fixing and connecting parts, they will not loosen or deviate due to vibrations caused by the opening and closing of the door. This prevents the rotating shaft from spinning freely and ensures the stability of the smart lock's unlocking. The threaded connection is stable, secure, and easier to disassemble. Workers only need to manually separate the geared motor and lock cylinder without needing other tools. Compared to screws, it is more secure and there is no need to worry about loosening due to vibrations caused by the opening and closing of the door. Threaded connections also have higher compatibility. Screws require precision between the holes and screws. Once the precision is off, the two cannot be matched. Threaded connections also allow the geared motor and lock cylinder to mesh firmly, achieving a tight seal. Threaded connections are also less expensive. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments:

[0023] A motor lock cylinder includes a geared motor 1 and a lock cylinder 2. The lock cylinder 2 contains a lock cylinder core 3. One end of the geared motor 1 is provided with a rotating shaft 4, which is connected to the lock cylinder core 3. The geared motor 1 can drive the lock cylinder core 3 to rotate through the rotating shaft 4. The upper end of the lock cylinder 2 is also provided with a connecting part, and the lower end of the geared motor 1 is provided with a fixing part. The geared motor 1 is fixedly connected to the connecting part on the lock cylinder 2 through the fixing part. The connecting part is an internal thread 7, and the fixing part is an external thread 8. The geared motor 1 is threadedly connected to the internal thread 7 on the lock cylinder 2 through the external thread 8. This utility model adopts a threaded connection.

[0024] This utility model relates to a motor lock cylinder, comprising a geared motor 1 and a lock cylinder 2. The lock cylinder 2 contains a lock cylinder core 3. One end of the geared motor 1 has a rotating shaft 4 connected to the lock cylinder core 3. Driving the geared motor 1 allows it to rotate the lock cylinder core 3 via the rotating shaft 4. The upper end of the lock cylinder 2 has a connecting part, and the lower end of the geared motor 1 has a fixing part. The geared motor 1 is fixedly connected to the connecting part on the lock cylinder 2 via the fixing part. This utility model, by providing a connecting part on the lock cylinder 2 and a fixing part at the lower end of the geared motor 1, connects and fixes the lock cylinder 2 and the geared motor 1, thus fixing their positions and preventing movement. When the geared motor 1 drives the lock cylinder core 3 to rotate, the lock cylinder core 3 will not move. The lock cylinder 2 rotates synchronously, and after the lock cylinder 2 and the reduction motor 1 are fixed by the fixing part and the connecting part, they will not loosen or deviate due to the vibration caused by the opening and closing of the door. This prevents the rotating shaft 4 from spinning freely, ensuring the stability of the smart lock. The threaded connection is stable, secure, and easier to disassemble. Workers only need to manually separate the reduction motor 1 and the lock cylinder 2 without needing to find other tools. It is more secure than screws, and there is no need to worry about loosening due to the vibration caused by the opening and closing of the door. The threaded connection has higher compatibility. Screws require the precision between the hole and the screw. Once the precision is deviated, the two cannot be matched.

[0026] Preferably, a rotating component 11 is provided between the geared motor 1 and the lock cylinder 2. One end of the rotating component 11 is connected to the rotating shaft 4, and the other end is connected to the lock cylinder core 3. In the working state, the rotating shaft 4 drives the lock cylinder core 3 to rotate through the rotating component 11, so that the rotating shaft 4 can better drive the lock cylinder core 3 to rotate, ensuring the stability of the smart lock unlocking and making the connection simple and convenient.

[0027] Preferably, the geared motor 1 includes a drive motor 12 and a gearbox 13. The drive motor 12 is provided with a motor shaft, and the drive motor 12 is connected to the gearbox 13 through the motor shaft. The rotating shaft 4 is located at the lower end of the gearbox 13.

[0028] Preferably, the gearbox 13 contains several layers of planetary gears and sun gears. The motor shaft meshes with the planetary gears at the upper end of the gearbox 13 to drive the sun gear to rotate. The sun gear drives the planetary gears mounted on the next layer of support, forming a multi-stage rotational connection. The deceleration is completed by driving the sun gear to rotate through the meshing connection of the planetary gears, which has strong stability and avoids excessive speed caused by the drive motor 12.

[0029] Preferably, the lower end of the rotating shaft 4 is a waist-shaped rod, and the rotating component 11 is provided with a waist-shaped hole that matches the waist-shaped hole, so as to reduce wear and not affect the normal use of the smart lock.
