[0002] In the door lock industry, traditional clutch structures usually require manual operation or complex mechanical structures to achieve the clutch function. The design of traditional clutch structures not only increases the manufacturing cost, but also may lead to inconvenient operation and reliability problems.

[0003] In the prior art, traditional clutch structures mostly adopt springs, cams or other mechanical components. These components are prone to wear due to long-term use, resulting in performance degradation or failure. In addition, traditional clutch structures have deficiencies in automation and cannot meet the high requirements of modern door locks for intelligence and automation. Therefore, it is of great significance to develop a new type of door lock structure with simple structure, high reliability and automatic clutch function. Summary of the Invention

[0004] In view of the deficiencies of the existing methods, this application proposes a door lock and its clutch structure to solve the technical problems of complex structure and poor reliability existing in traditional clutch structures.

[0005] To achieve the above object, this application provides the following technical solutions:

The planetary assembly includes a sun gear and planetary gears that mesh with each other. The sun gear rotates coaxially with the input shaft. The planetary gears are coaxially connected with a pushing member extending radially along the planetary gears.

[0007] When the pushing member rotates with the planetary gear and abuts against the output shaft, the output shaft is controlled by the pushing member and rotates with the rotation of the pushing member. When the pushing member rotates reversely with the planetary gear and moves away from the output shaft, the output shaft returns to the free rotation state.

[0008] Further setting: There are at least three planetary gears, and the planetary gears are evenly distributed along the circumferential direction of the sun gear. Each planetary gear is provided with a pushing member.

[0037] In view of the problem that in the current door lock industry, the traditional clutch structure usually requires manual operation or a complex mechanical structure to achieve the clutch function, resulting in inconvenient operation and low reliability, the present application provides a clutch structure. Please refer to Figures 1 to 5 which can be applied to a door lock, uses a simple mechanical structure to automate the clutch function, has high reliability, effectively reduces the risk of failure caused by wear of mechanical components, and then improves the overall reliability of the door lock.

[0038] Please combine Figures 1 to 3 As shown in, the clutch structure 1 of the present application includes a bracket 11 and an input shaft 12, a planetary assembly 13 and an output shaft 14 sequentially arranged on the bracket 11. Among them, the input shaft 12 is rotatably installed on the bracket 11, and the input shaft 12 is connected to a driving source to drive the input shaft 12 to rotate through the driving source. The planetary assembly 13 is arranged between the input shaft 12 and the output shaft 14 to achieve the coupled state and decoupled state of the clutch between the input shaft 12 and the output shaft 14 through the planetary assembly 13. The planetary assembly 13 includes a sun gear 131 and a planetary gear 132 that mesh with each other. The sun gear 131 rotates coaxially with the input shaft 12, and the planetary gear 132 is coaxially connected with a pushing member 133 extending radially along the planetary gear 132, and the pushing member 133 rotates with the rotation of the planetary gear 132.

[0039] It should be noted that there is no direct interference between the planet gear 132 and the output shaft 14 of the present application. The planet gear 132 and the output shaft 14 can rotate relatively independently. In this embodiment, the pushing member 133 is a push rod extending radially along the planet gear 132, and the length of the push rod is greater than the radius of the planet gear 132, so that the push rod can rotate with the planet gear 132 until it abuts against the output shaft 14, thereby the output shaft 14 can be pushed by the push rod to achieve the purpose of clutch coupling. The specific structure of the pushing member 133 is not limited to the push rod disclosed in this embodiment, and can also be designed into various shapes and structures, specifically depending on the requirements and design purposes of the transmission process. That is, the sun gear 131 and the planet gear 132 of the planet assembly 13 in this embodiment are used as the transmission structure between the input shaft 12 and the pushing member 133, and the input shaft 12 and the output shaft 14 are coupled by the pushing member 133 abutting against the output shaft 14. In other embodiments, the transmission structure can also be set as a sprocket chain structure or a synchronous belt structure to achieve the transmission between the input shaft 12 and the pushing member 133.

[0040] Specifically in this embodiment, the drive source is a motor 301. The motor shaft of the motor 301 is fixedly connected to the input shaft 12. The bracket 11 is relatively fixed to the base of the motor 301. The input shaft 12 can achieve relative rotation with the bracket 11 through bearings. The input shaft 12 is controlled by the motor 301 and rotates under the drive of the motor 301. The input shaft 12 drives the sun gear 131 to rotate, so that the planet gear 132 meshing with the sun gear 131 rotates synchronously.

[0041] In order to improve the transmission efficiency and stability between the input shaft 12 and the sun gear 131, the sun gear 131 and the input shaft 12 in this embodiment are of an integrally formed structure, which can improve the torsional stiffness of the overall structure, reduce the risk of elastic deformation, improve the stability of power transmission under high loads, and the integral structure is also beneficial to reducing the number of parts and assembly processes, and can reduce the risk of cumulative processing errors. In other embodiments, the input shaft 12 and the sun gear 131 can also be connected by a coupling to achieve coaxial rotation of the sun gear 131 and the input shaft 12, and the specific structure can be set according to the actual use situation.

[0042] When the push rod rotates with the planet gear 132 and abuts against the output shaft 14, the output shaft 14 and the input shaft 12 reach a coupled state through the planetary assembly 13. The output shaft 14 is controlled by the push rod, and the tangential component force of the rotation of the push rod will push the output shaft 14 to rotate synchronously. Subsequently, the rotation of the output shaft 14 can be controlled through the input shaft 12, which is convenient for controlling the opening of the door lock. When the motor reversely drives the input shaft 12 to rotate, that is, the rotation direction is opposite to the rotation direction for making the push rod abut against the output shaft 14, the pushing member 133 rotates away from the output shaft 14 with the planet gear 132. After rotating within a certain angle range, the output shaft 14 and the input shaft 12 are in a disengaged state, and the output shaft 14 returns to the free rotation state. At this time, the rotation of the output shaft 14 can no longer be controlled through the input shaft 12.

[0043] Furthermore, there are at least three planet gears 132, and each planet gear 132 is provided with a pushing member 133. In this embodiment, there are three planet gears 132, and the three planet gears 132 are evenly distributed along the circumferential direction of the sun gear 131. Then, the output shaft 14 is rotated by the simultaneous action of the three pushing members 133. The radial forces generated by the multiple pushing members 133 on the output shaft 14 are balanced with each other, and it can also avoid excessive single-point force, which can significantly improve the transmission capacity of the planetary assembly 13. At the same time, the output shaft 14 will exert a reaction force on the pushing member 133. Using three pushing members 133 can disperse the tangential force of the output shaft 14 on the planet gear 132, reduce the contact stress between the planet gear 132 and the sun gear 131, reduce the risk of failure caused by long-term wear of the components, and extend the service life of the components.

[0044] On the circumferential surface of the output shaft 14, there is also an abutting surface 141 for abutting against the pushing member 133. The abutting surface 141 is the key contact part for transmitting force and motion between the pushing member 133 and the output shaft 14, and the number of the abutting surfaces 141 is the same as the number of the pushing members 133, ensuring that each pushing member 133 has an independent acting point, which can avoid interference or clearance during the power transmission process and ensure the continuity of the transmission. At the same time, the synchronous cooperation of the multiple pushing members 133 and the abutting surfaces 141 can achieve the superimposed output of torque, so that the multiple pushing members 133 jointly hold the output shaft 14 tightly. Subsequently, the rotation of the input shaft 12 can be reversely driven through the output shaft 14, ensuring the overall transmission efficiency.

[0045] The planetary assembly 13 of the present application further includes a planetary carrier 134. The planetary carrier 134 is the core load-bearing component for the transmission of the planet gear 132. The planet gear 132 is rotatably installed on the planetary carrier 134 through a planetary shaft 135. The planetary carrier 134 plays a role in supporting and limiting the planet gear 132, ensuring the meshing accuracy between the planet gear 132 and the sun gear 131, so that the sun gear 131 and the planet gear 132 can form a stable power transmission framework, ensuring the stability of the transmission of the planetary assembly 13.

[0046] Further, the bracket 11 is provided with a mounting groove 111, and the planetary bracket 134 is embedded in the mounting groove 111 and can rotate relative to the bracket 11. At the same time, an elastic pad 15 is provided between the planetary bracket 134 and the bracket 11. The elastic pad 15 increases the frictional force between the planetary bracket 134 and the bracket 11 to inhibit the unexpected rotation of the planetary assembly 13 caused by inertia or external vibration, and avoid affecting the coupling effect between the planetary assembly 13 and the output shaft 14.

[0047] In addition, the output shaft 14 is supported by a fixing member 16 that is relatively fixed to the bracket 11. The output shaft 14 is inserted into the fixing member 16 and rotates relative to the fixing member 16, thereby limiting the output shaft 14, reducing the risk of eccentric load during rotation of the output shaft 14, enhancing the anti-torsion ability, preventing the output shaft 14 from moving axially during rotation, and improving the rotational stability of the output shaft 14. In this embodiment, a rolling bearing can be used to achieve low-friction relative rotation between the output shaft 14 and the fixing member 16, ensuring stability during torque transmission.

[0048] The clutch structure 1 of the present application mainly realizes the clutch function between the input shaft 12 and the output shaft 14 through the planetary gear structure in cooperation with the pusher 133. The structure is simple, reducing the complex mechanical parts in the traditional clutch structure 1, simplifying the mechanical structure, reducing the failure risk caused by wear between a large number of mechanical parts, improving the reliability of the overall structure, and also reducing the manufacturing cost. At the same time, the driving source for controlling the rotation of the input shaft 12 in the present application can adopt a motor 301, thereby realizing the automation of the clutch function without manual operation, improving the convenience of use.

[0049] The present application also relates to a door lock applying the above clutch structure 1. Please refer to Figure 6 which includes a clutch structure 1, a driving source, and a lock tongue. Among them, the driving source is connected to the input shaft 12 of the clutch structure 1, and the lock tongue is connected to the output shaft 14 of the clutch structure 1. The driving source realizes the clutch function of the clutch structure 1 by driving the rotation of the input shaft 12, and then achieves the purpose of controlling the telescopic movement of the lock tongue to realize the unlocking or locking of the door lock.

[0050] The driving source of this embodiment includes a motor 301 and a power supply 302 for supplying electrical energy to the motor 301. The motor shaft of the motor is fixedly connected to the input shaft 12 of the clutch structure 1 to facilitate the motor 301 to control the rotation of the input shaft 12. In addition, the present application does not limit the rotation direction of the planetary assembly 13 in the clutch structure 1. Therefore, the motor 301 can realize the control of the clutch structure 1 both in the forward rotation and reverse rotation, so that the clutch state of the clutch structure 1 can be flexibly controlled according to actual needs, with strong flexibility.

[0051] Further, the present application further includes an unlocking module. The unlocking module is used to obtain unlocking information and verify whether the unlocking information matches the preset information. When it is determined that the unlocking information matches the preset information, the unlocking module is used to send a control signal to the drive source, and the drive source is used to respond to the received control signal and drive the input shaft 12 of the clutch structure 1 to rotate. The present application can be unlocked by means of password, fingerprint recognition, face, etc. Or, a corresponding unlocking signal can also be sent from a mobile phone or other wireless device to the unlocking module, so that the unlocking module can send a corresponding control signal to the drive source according to the unlocking signal.

[0052] In a specific embodiment, the door lock further includes a housing 2. The housing 2 is fixed to the door panel through a bottom plate 21. The clutch structure 1 and the drive source are arranged in the accommodation space formed by the combination of the housing 2 and the bottom plate 21. The housing 2 is provided with a knob 4 on its side relative to the bottom plate 21. The knob 4 is rotatably arranged on the housing 2 and is connected to the output shaft 14, so as to facilitate the user to rotate the knob 4 behind the door to control the rotation of the output shaft 14 for unlocking. In this embodiment, by arranging the clutch structure 1 and the drive source of the door lock in the accommodation space formed by the housing 2 and the bottom plate 21, a module that can be independently installed and disassembled can be formed. In addition, the door lock of this embodiment further includes a panel (not shown in the figure). The panel and the housing 2 are respectively arranged on both sides of the door panel. The panel is provided with an unlocking module that can input unlocking information through password, fingerprint or other unlocking methods, so as to facilitate the user to input unlocking information for unlocking. In this embodiment, by setting a double-sided operation structure on both sides of the door panel, the unlocking module realizes the verification of unlocking information for electronic unlocking, and the knob 4 of the housing 2 can provide internal mechanical control, forming a two-way operation logic. The user does not need to separately debug each component, and the door lock module can be quickly docked and installed with the door panel through a standardized interface, simplifying the assembly process of the door lock and the door panel and reducing the installation complexity.

[0053] In another embodiment, the clutch structure 1, the drive source and the unlocking module can be directly arranged inside the door panel. The unlocking module can be unlocked by receiving signals sent from a mobile phone or other wireless devices. Through the combination of internalization of mechanical components and wireless control technology, the unity of the anti-destruction ability and intelligent convenience of the door lock is realized.

[0054] During the unlocking process of the door lock of the present application, when the unlocking information of the unlocking module is successfully verified and matched with the preset signal, the unlocking module sends a control signal to the drive source. After receiving the control signal, the motor 301 drives the input shaft 12 of the clutch structure 1 to rotate. While the input shaft 12 rotates to drive the sun gear 131, since the planet gear 132 meshes with the sun gear 131, the planet gear 132 rotates synchronously. After the planet gear 132 rotates to a certain angle, the pushing member 133 coaxially connected to the planet gear 132 abuts against the output shaft 14. Please refer to Figure 4, that is, it reaches the state where the output shaft 14 is coupled to the input shaft 12. Subsequently, the motor 301 can continue to rotate to transmit power to the lock tongue through the input shaft 12, the planetary assembly 13, and the output shaft 14, so as to control the telescopic movement of the lock tongue, and then control the door lock to unlock or lock.

[0055] It should be noted that during the above process of electronically controlling the movement of the lock tongue, the clutch structure 1 always remains in a coupled state, ensuring that the rotation of the input shaft 12 can be continuously and effectively transmitted to the lock tongue to achieve the purpose of controlling the opening of the door lock.

[0056] When the motor 301 drives the input shaft to rotate in the reverse direction and drives the planet gear 132 to rotate in the reverse direction through the sun gear 131, the pushing member 133 gradually moves away from the output shaft 14 as the planet gear 132 rotates. Please refer to Figure 5 , and the clutch decoupling state can be achieved. At this time, the output shaft 14 returns to a free state and can no longer control the movement of the lock tongue through the input shaft 12.

[0057] In summary, the clutch structure 1 of the present application can be applied to various door lock systems, especially suitable for intelligent door locks, which can greatly improve the intelligent level and market competitiveness of door locks.

[0058] The above-mentioned clutch structure 1 simplifies the mechanical structure and adopts a combined design of a planetary structure model and a bracket 11 to achieve the clutch function between the input shaft 12 and the output shaft 14. It reduces the complex mechanical components used in the traditional clutch structure 1, reduces the risk of failures caused by mechanical component wear, improves the overall reliability of the clutch structure 1, ensures the normal operation of the door lock switch, and extends the service life of the door lock.

[0059] When the clutch structure 1 of the present application is applied to an intelligent door lock, the unlocking operation is used to control the motor 301 to drive and realize the automation of the clutch structure 1, eliminating the need for manual operation, improving the convenience for users, and greatly enhancing the user experience.

[0060] The above are only some embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
