Abstract
Description
Technical Field
[0001] The present application relates to the technical field of clutch devices, and in particular to an anti-stuck clutch door lock. Background Art
[0002] Door lock devices are widely used in various occasions, such as homes, offices, and industrial equipment. Their main function is to ensure safety and convenience. Traditional door lock designs usually use mechanical structures to achieve locking and unlocking functions. These designs have been very mature after years of development, but they still have shortcomings in certain specific application scenarios. For example, in smart door locks and automation systems, in order to improve safety, more complex mechanical structures need to be introduced to prevent jamming caused by external interference. This improvement not only improves the user experience, but also enhances the reliability of the system. The existing door lock anti-jamming mechanism mainly includes several common design schemes. The first is the spring reset door lock, which uses the elastic force of the spring to automatically return to the initial position to avoid jamming. The second is the sliding door lock, which uses the design of sliders or other moving parts to enable the door lock to return to normal even when the force is uneven. In addition, there is a rotary door lock, which uses a rotating mechanism to open and close the door lock, while using friction or other methods to prevent jamming. Although these solutions have solved the jamming problem to a certain extent, there are still some limitations.
[0003] Invention patent publication number CN118029781A discloses an integrated motor reduction gearbox for electronic door locks. The gearbox includes a housing, a motor is mounted on the housing, a handle shaft and an output shaft are mounted in the center of the housing, and a clutch device is mounted between the handle shaft and the output shaft. The gearbox can pull the retaining ring and the clutch roller to reset through the retaining ring spring, so that the handle shaft and the output shaft are in a separated state. Only when the handle shaft rotates, the output shaft and the handle shaft are locked together and rotate synchronously. Since the output shaft and the handle shaft are separated at ordinary times, the output shaft will not drive the handle shaft to rotate during the rotation of the output shaft. The rotation of the output shaft is not limited by the handle shaft, which effectively reduces the load on the motor. After the rotation is completed, it is necessary to pull the retaining ring and the clutch ball to reset to separate the clutch. When the motor is stuck, it is difficult to separate the hand shaft and the output shaft, resulting in difficulty in clutch separation. Summary of the invention
[0004] The purpose of the present application is to provide an anti-stuck clutch door lock and a method of using the same, so as to solve the problem of difficulty in clutch disengagement when the motor is stuck.
[0005] In the first aspect, the present application provides an anti-stuck clutch door lock adopts the following technical solution: An anti-stuck clutch door lock, comprising: A door lock assembly is arranged on the housing, comprising a door lock shaft and a door lock gear, wherein the door lock gear is arranged on the door lock shaft; A clutch assembly is arranged in the housing, and comprises an input gear, a clutch swing arm, a clutch gear and a first transition gear. The input gear and the first transition gear are both mounted on the inner wall of the housing. The first transition gear is meshed with the door lock gear. The input gear is axially connected to the clutch swing arm for rotation. The clutch swing arm is mounted and connected to the clutch gear so that the clutch gear can rotate relative to the input gear. The first clutch gear is meshed with the input gear. Wherein, as the clutch gear rotates relative to the input gear, the clutch gear can mesh with the first transition gear to transmit rotation to the first transition gear.
[0006] By adopting the above technical solution, when the input gear rotates, since the clutch gear is meshed with the input gear, the clutch gear is installed on a clutch swing arm that can rotate relative to the input gear, and the clutch gear is not subject to resistance at the other end, the clutch gear will not rotate, but rotate relative to the input gear under meshing. When the clutch gear rotates to the other side to mesh with the first transition gear, the clutch gear forms meshing on the other side and is subject to resistance, so that the clutch gear can no longer rotate relative to the input gear, and the rotation is transmitted to the first transition gear through meshing. When the drive is finished, since the input gear cannot rotate at this time, it is only necessary to rotate the door lock shaft in the opposite direction so that the first transition gear pushes the clutch gear to rotate relative to the input gear, so that the clutch gear and the first transition gear are separated, thereby completing the clutch operation of the clutch assembly. By using the clutch swing arm and clutch gear to perform clutch operation, when the clutch needs to be connected, only the input gear needs to be rotated to achieve automatic clutch connection. When the clutch needs to be disengaged, only a small amount of reverse rotation of the door lock shaft is required. After the clutch gear is pushed to separate from the first transition gear, the door lock shaft can rotate freely to achieve clutch disengagement, making the clutch operation more convenient and quick. In addition, when the motor is stuck, the clutch can be disengaged by rotating the door lock shaft in the opposite direction to avoid the influence of the motor stuck on the use of the door lock.
[0007] Optionally, a rotation damper is installed between the clutch gear and the clutch swing arm.
[0008] By adopting the above technical solution, if the rotational resistance between the clutch gear and the clutch swing arm is small, and the rotational resistance of the clutch swing arm relative to the input gear is large, when the input gear rotates, it will be difficult to drive the clutch gear to rotate relative to itself. Instead, the clutch gear will idle in place, resulting in the clutch being unable to connect automatically. Therefore, by installing a rotational damper between the clutch gear and the clutch swing arm, the rotational damper can increase the self-rotation resistance of the clutch gear, so that it can start to rotate relative to the input gear first under the drive of the input gear, thereby ensuring the stability of the automatic connection of the clutch.
[0009] Optionally, the number of the clutch gears is two, and the two clutch gears are respectively installed on both sides of the input gear.
[0010] By adopting the above technical solution, by providing a clutch gear on each side of the input gear, the clutch gear can quickly engage with the first transition gear when the input gear rotates in both directions, thereby reducing the idling distance of the input gear and improving the clutch efficiency.
[0011] Optionally, the clutch swing arm is bent toward the first transition gear.
[0012] By adopting the above technical solution, the clutch swing arm bent toward the first transition gear can be arranged closer to the first transition gear, so that the clutch gear can quickly contact the first transition gear while reducing the space occupied by the clutch assembly and improving space utilization.
[0013] Optionally, it also includes an input component, which includes an input motor, a threaded sleeve, and a second transition gear. The input motor is installed in the housing, the threaded sleeve is arranged on the output shaft of the input motor, and the second transition gear is respectively engaged with the threaded sleeve and the input gear.
[0014] By adopting the above technical solution, the input motor is used to input rotation into the clutch motor, the threaded sleeve is connected to the output shaft of the input motor, and meshes with the second transition gear, which can change the rotation direction of the output shaft and convert the rotation of the input motor into the rotation of the gear. The second transition gear allows power to be smoothly transmitted from the input motor to the input gear, further driving the entire clutch assembly to work.
[0015] Optionally, the shell is provided with a door lock hole and a mounting cover, the door lock opening is arranged corresponding to the door lock shaft, and the inner wall of the shell is provided with a gear mounting hole and a motor support frame for installing gears and the input motor.
[0016] By adopting the above technical solution, the door lock hole and mounting cover on the housing can ensure the accurate positioning and fixation of the door lock shaft and the input motor, improving the stability and reliability of the structure. At the same time, the gear mounting hole and motor support frame on the inner wall of the housing further enhance the installation accuracy and stability of the internal components, reduce vibration and noise during operation, and improve the overall performance.
[0017] Optionally, a door lock bearing is sleeved on the door lock shaft, and the door lock bearing is installed on the inner side of the shell to support the door lock shaft.
[0018] By adopting the above technical solution, the door lock bearing can ensure the stability of the door lock shaft during the rotation process, improve the running stability and service life of the door lock assembly. At the same time, the installation of the door lock bearing is stable, ensuring the stable support of the door lock shaft in the housing, and enhancing the reliability of the entire door lock structure.
[0019] In a second aspect, the present application provides a method for using a clutch door lock using the following technical solution: A method for using a clutch door lock, based on the anti-stuck clutch door lock as described above, comprises: S1, driving the input gear to rotate, so as to push the clutch gear to rotate to mesh with the first transition gear; S2. Rotate the door lock shaft in the opposite direction to push the clutch gear to rotate along the input gear and separate from the first transition gear.
[0020] By adopting the above technical solution, before the clutch door lock rotates, the clutch gear is separated from the first transition gear. At this time, the door lock shaft is only connected to the first transition gear, so that it can rotate freely without restriction. When the input gear starts to rotate, the input gear drives the meshed clutch gear to rotate through the clutch swing arm, so that the other side of the clutch gear meshes with the first transition gear, thereby realizing automatic clutch connection. When the drive is completed, if the door lock shaft needs to be rotated freely, the door lock can be rotated in the opposite direction of the previous drive direction, so that the first transition gear pushes the clutch gear. Although the input gear is in a stationary state at this time, the clutch swing arm and the clutch gear can still rotate. By rotating the door lock shaft in the opposite direction, the first transition gear pushes the clutch gear away, releasing the meshing state, so that the clutch is disengaged and the door lock shaft can rotate freely.
[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the input gear rotates, the clutch gear is meshed with the input gear. The clutch gear is installed on a clutch swing arm that can rotate relative to the input gear, and the clutch gear has no resistance at the other end. Therefore, the clutch gear will not rotate, but rotate relative to the input gear under meshing. When the clutch gear rotates to the other side to mesh with the first transition gear, the clutch gear forms meshing on the other side and encounters resistance, so that the clutch gear can no longer rotate relative to the input gear, and the rotation is transmitted to the first transition gear through meshing. When the drive is finished, since the input gear cannot rotate at this time, it is only necessary to rotate the door lock shaft in the opposite direction so that the first transition gear pushes the clutch gear to rotate relative to the input gear, so that the clutch gear and the first transition gear are separated, thereby completing the clutch operation of the clutch assembly. By using the clutch swing arm and clutch gear to perform clutch operation, when the clutch needs to be connected, only the input gear needs to be rotated to achieve automatic clutch connection. When the clutch needs to be disengaged, only the door lock shaft needs to be slightly rotated in the opposite direction. After the clutch gear is pushed to separate from the first transition gear, the door lock shaft can rotate freely to achieve clutch separation, making the clutch operation more convenient and quick. When the motor is stuck, the clutch can also be disengaged by rotating the door lock shaft in the opposite direction to avoid the influence of the motor stuck on the use of the door lock. ; 2. If the rotational resistance between the clutch gear and the clutch swing arm is small, and the rotational resistance of the clutch swing arm relative to the input gear is large, when the input gear rotates, it will be difficult to drive the clutch gear to rotate relative to itself, but will cause the clutch gear to idle in situ, resulting in the inability of the clutch to automatically connect. Therefore, by installing a rotation damper between the clutch gear and the clutch swing arm, the rotation damper can increase the self-rotation resistance of the clutch gear, so that it can start to rotate relative to the input gear first under the drive of the input gear, thereby ensuring the stability of the automatic connection of the clutch; 3. Before the clutch door lock rotates, the clutch gear is separated from the first transition gear. At this time, the door lock shaft is only connected to the first transition gear, so that it can rotate freely without restriction. When the input gear starts to rotate, the input gear drives the meshed clutch gear to rotate through the clutch swing arm, so that the other side of the clutch gear meshes with the first transition gear, thereby realizing automatic clutch connection. After the drive is completed, if the door lock shaft needs to be rotated freely, the door lock can be rotated in the opposite direction of the previous drive direction, so that the first transition gear pushes the clutch gear. Although the input gear is stationary at this time, the clutch swing arm and the clutch gear can still rotate. By rotating the door lock shaft in the opposite direction, the first transition gear pushes the clutch gear away, releasing the meshing state, so that the clutch is disengaged and the door lock shaft can rotate freely.

DETAILED DESCRIPTION
[0024] The present application is further described in detail below in conjunction with the accompanying drawings.
[0025] The present application provides an embodiment, an anti-stuck clutch door lock, referring to Figure 1 and 2 , including a door lock assembly 1, a clutch assembly 2, an input assembly 3 and a housing 4, wherein the housing 4 is the installation body of the clutch door lock, and the door lock assembly 1, the clutch assembly 2 and the input assembly 3 are all installed in the housing 4. Door lock holes 41 are respectively provided on both sides of the housing 4, and the door lock assembly 1 includes a door lock shaft 11, a door lock gear 12 and a door lock bearing 13, wherein the door lock shaft 11 protrudes from the door lock holes 41 on both sides of the housing 4, and both ends of the door lock shaft 11 are provided with connection ports 14, through which the equipment required to be applied can be connected on both sides of the door lock, thereby improving the applicability of the door lock. The part of the door lock shaft 11 located on the inner side of the housing 4 is connected to the door lock gear 12 and the door lock bearing 13, and the door lock bearing 13 is provided on the inner side wall of the housing 4, and is used to rotate and support the door lock shaft 11, and the door lock gear 12 is sleeved on the outer side of the door lock shaft 11, and is used to receive the rotation transmitted by the clutch assembly 2, so that the door lock shaft 11 can be driven to rotate.
[0026] Reference Figure 2 and 3The outer side of the housing 4 is also provided with a mounting cover 42, which can be opened to facilitate adjustment of internal parts without disassembling the housing 4, thereby improving the applicability of the clutch door lock. The inner side of the housing 4 is also provided with a gear mounting hole 43 and a motor support frame 44, wherein the gear mounting hole 43 is provided for mounting the gears of the components inside the housing 4, and the motor support frame 44 can support the input motor 31 in the input component 3. By providing the gear mounting hole 43 and the motor support frame 44, each component can be stably mounted in the housing 4, thereby improving the stability of the clutch door lock.
[0027] Reference Figure 4 and 5 The clutch assembly 2 includes an input gear 21, a clutch swing arm 22, a clutch gear 23 and a first transition gear 24, wherein the input gear 21 and the first transition gear 24 are both mounted on the inner wall of the housing 4 through the gear mounting hole 43, and the input gear 21 and the first transition gear 24 are both double-layer structures, and the upper and lower layers of gears are of different sizes. Through the synchronous rotation of the upper and lower layers, the upper and lower layers of gears with the same angular velocity can correspond to different linear velocities, thereby realizing the amplification or reduction of the rotation speed, making the operation of the clutch door lock more stable. The first transition gear 24 is meshed with the door lock gear 12, and is used to transmit rotation to the door lock gear 12 when the clutch assembly 2 is connected, so as to drive the door lock shaft 11 to rotate.
[0028] Reference Figure 5 and 6The clutch swing arm 22 is connected to the rotating shaft of the input gear 21 and can rotate relative to the input gear 21. The clutch swing arm 22 is curved, and the bending direction is the direction close to the first transition gear 24. A clutch gear 23 is installed at each end of the clutch swing arm 22. The clutch gear 23 can rotate relative to the clutch swing arm 22, and both clutch gears 23 are meshed with the input gear 21. The clutch gear 23 is meshed with the input gear 21, which not only enables the clutch gear 23 to rotate under the drive of the input gear 21, but also because the clutch gear 23 is installed on the clutch swing arm 22 that can rotate relative to the input gear 21, when the input gear 21 rotates and the clutch gear 23 does not rotate, the clutch gear 23 can rotate around the input gear 21. As the clutch gear 23 rotates relative to the input gear 21, the clutch gear 23 will eventually contact with the first transition gear 24 and mesh with the first transition gear 24. At this time, the position of the clutch gear 23 is fixed, and it meshes with the input gear 21 and the first transition gear 24 respectively, so that the input gear 21 can transmit rotation to the first transition gear 24 through the clutch gear 23, and the automatic connection of the clutch assembly 2 is realized through the rotation of the input gear 21. However, it should be noted that the automatic connection of the clutch requires the input gear 21 to keep rotating in the same direction. When the rotation direction of the input gear 21 changes, the clutch gear 23 will rotate in the opposite direction around the input gear 21, thereby separating from the first transition gear 24. The input gear 21 needs to idle for a distance before the clutch gear 23 can be reconnected with the first transition gear 24 at the other end, thereby realizing the automatic connection of the clutch rotating in different directions. There are two clutch gears 23, and they are respectively arranged on both sides of the input gear 21, so that when the input gear 21 rotates in both directions, it can quickly connect to the first transition gear 24, thereby improving the clutch efficiency of the clutch assembly 2.
[0029] Reference Figure 7 A rotation damper 25 is provided at the connection between the clutch gear 23 and the clutch swing arm 22. When the clutch gear 23 is not meshed with the first transition gear 24, in order to make the input gear 21 drive the clutch gear 23 to rotate around the input gear 21, that is, the input gear 21 and the clutch gear 23 are relatively stationary, it is necessary to keep the clutch gear 23 and the clutch swing arm 22 relatively stationary. Therefore, by providing the rotation damper 25, the rotation resistance between the clutch gear 23 and the clutch swing arm 22 will not be too small, so as to avoid the input gear 21 driving the clutch gear 23 to idle, and ensure that the clutch can be connected normally.
[0030] Reference Figure 4The input assembly 3 includes an input motor 31, a threaded sleeve 32 and a second transition gear 33, wherein the input motor 31 and the second transition gear 33 are both mounted on the inner side of the housing 4, the input motor 31 is correspondingly mounted on the motor support frame 44, and the second transition gear 33 is mounted on one of the gear mounting holes 43. The threaded sleeve 32 is sleeved on the output shaft of the input motor 31, and the threaded sleeve 32 is meshed with the second transition gear 33, thereby transmitting rotation to the second transition gear 33 and changing the rotation direction output by the input motor 31. The second transition gear 33 is meshed with the input gear 21, thereby transmitting the rotation input by the input motor 31 to the second transition gear 33, and then transmitting the rotation to the door lock shaft 11 through the clutch assembly 2, completing the motor driving process.
[0031] The implementation principle of the embodiment of the present application is as follows: the input component 3 drives the input gear 21 to drive the clutch gear 23 to mesh with the first transition gear 24, and completes the automatic clutch connection, so that when the motor is not inputting rotation, the door lock shaft 11 can rotate freely without hindrance, and when the input component 3 drives the input gear 21 to rotate, the clutch component 2 can complete the automatic clutch connection, so that the use of the clutch component 2 is more convenient. When the motor drive stops, the door lock shaft 11 is rotated in the opposite direction along the driving direction, so that the door lock shaft 11 drives the first transition gear 24 to rotate in the opposite direction through the door lock gear 12, so that the clutch gear 23 is pushed away from the first transition gear 24, so as to release the clutch connection. The method of releasing the clutch connection by reverse rotation can conveniently and quickly complete the clutch separation, making the use of the clutch simpler and more convenient. Even if the motor is locked, the clutch can be released to ensure the normal use of the door lock shaft 11.
[0032] The present application provides an embodiment, a method for using a clutch door lock, based on the anti-stuck clutch door lock as described above, referring to Figure 8 , including the following steps: S01 . Drive the input gear 21 to rotate, so as to push the clutch gear 23 to rotate until it meshes with the first transition gear 24 .
[0033] Specifically, the input motor 31 is started to drive the input gear 21 to rotate. When the input gear 21 rotates, the clutch gear 23 meshing with the input gear 21 rotates around the input gear 21. After the clutch gear 23 rotates to mesh with the first transition gear 24, the input gear 21 keeps rotating, so that the rotation of the input gear 21 is transmitted to the first transition gear 24 through the clutch gear 23. In addition, by providing the clutch gears 23 on both sides of the input gear 21, when the input gear 21 rotates in both directions, the clutch gear 23 on the corresponding side can be quickly meshed with the first transition gear 24, and when the clutch gear 23 on one side is meshed, the clutch gear 23 on the other side is fixed by the clutch swing arm 22, and the clutch is maintained in idle rotation without affecting the clutch.
[0034] S02, rotating the door lock shaft 11 in the opposite direction to push the clutch gear 23 to rotate along the input gear 21 and separate from the first transition gear 24.
[0035] Specifically, when the input motor 31 stops driving, the input gear 21 connected to the input motor 31 is in a fixed state. At this time, the door lock shaft 11 is rotated in the opposite direction of the motor driving the door lock shaft 11, so that the door lock shaft 11 drives the first transition gear 24 to push the clutch gear 23 to rotate. Since the input gear 21 is in a stationary state, the clutch gear 23 will be pushed to rotate around the input gear 21, thereby separating from the first transition gear 24, and then completing the clutch separation operation. Since the clutch swing arm 22 can rotate freely relative to the input gear 21, the clutch gear 23 installed on the clutch swing arm 22 can also rotate freely relative to the input gear 21. Even if the motor is stuck and the input gear 21 cannot rotate, the clutch separation can still be completed, ensuring the normal use of the door lock shaft 11.
[0036] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
