[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0029] The utility model provides a handle locking device for an intelligent door lock, referring to Figure 1, the handle locking device of the intelligent door lock includes a housing 1, a lock core assembly 2, a handle assembly 3, and a locking assembly 4. Among them, the housing 1 has a lock core hole 11, the lock core assembly 2 is arranged in the lock core hole 11, and the lock core assembly 2 is used for unlocking and locking with a mechanical key. The handle assembly 3 is rotatably connected to the housing 1, and the handle assembly 3 can block or avoid the lock core hole 11.

[0030] The locking assembly 4 includes an elastic member 42 and a locking member 43 both arranged in the housing 1. The locking member 43 is slidably connected to the housing 1, and the elastic member 42 is used to provide a locking force for the locking member 43. The handle 32 assembly 3 includes a rotating member 31 and a handle 32. The rotating member 31 is arranged in the housing 1 and is rotatably connected to the housing 1. The handle 32 is arranged outside the housing 1 and is connected to the rotating member 31, and the handle 32 rotates synchronously with the rotating member 31. The locking member 43 has a locking state and an unlocking state. In the locking state, the locking member 43 locks the rotating member 31, and there is a wedge fit between the locking member 43 and the rotating member 31. The locking member 43 can gradually increase the locking force on the rotating member 31 as the handle 32 shakes.

[0031] Based on the above scheme, by locking the handle assembly 3 with the locking member 43, it is not easy for the handle assembly 3 to shake after resetting. Even when the handle assembly 3 is structurally worn, through the wedge fit between the locking member 43 and the rotating member 31, the locking member 43 can still provide a firm locking force for the handle assembly 3, and the handle assembly 3 can become tighter as it shakes. In this way, the phenomenon of the handle assembly 3 shaking is avoided, and in this way, the problem that the current handle 32 shakes and affects the user experience is well improved, the use reliability of the product is improved, and the user experience is enhanced.

[0032] When the handle 32 is reset, the locking member 43 first locks the rotating member 31 to restrict the rotation of the rotating member 31, thereby effectively preventing the handle 32 from rotating. The elastic member 42 provides an elastic force for the locking member 43, so that the locking member 43 is in floating contact with the rotating member 31. When the handle 32 shakes in the state where the locking member 43 and the rotating member 31 maintain a wedge fit, the locking member 43 can strengthen the wedge fit force with the rotating member 31 under the push of the elastic member 42, that is, it can provide a firm locking force for the rotating member 31, thereby firmly fixing the handle 32, realizing that the handle 32 becomes more locked as it shakes, so as to improve the comfort of the user rotating the handle 32 and enhance the product use experience.

[0033] The handle 32 is arranged vertically. When not rotated, the handle 32 blocks the lock core hole 11, which is a hidden design and can prevent the lock core hole 11 from being exposed and cracked by others. When the handle 32 rotates, it can expose the lock core hole 11, facilitating the user to insert the key into the lock core hole 11 for unlocking and locking operations.

[0034] The housing 1 assembly includes a front lock housing 12 and a front sealing plate 13, the front sealing plate 13 is fixed to the front lock housing 12 by screws, the front sealing plate 13 and the front lock housing 12 cooperate to form a receiving cavity, the receiving cavity is used to receive the lock core assembly 2 and the locking assembly 4, and the locking assembly 4 is arranged at the bottom of the receiving cavity. The lock core hole 11 runs through the front sealing plate 13 and the front lock housing 12.

[0035] The lock core assembly 2 may be a mechanical lock core structure, which is unlocked by a mechanical key to achieve unlocking of the handle locking device of the smart door lock.

[0036] Reference Figures 1 to 5 The rotating member 31 is provided with a matching portion 311, the matching portion 311 has a first wedge-shaped wall surface 3111, the locking member 43 is provided with a locking protrusion 431, the locking protrusion 431 has a second wedge-shaped wall surface 4311, the locking protrusion 431 is locked with the matching portion 311, and under the action of the elastic member 42, the contact area between the first wedge-shaped wall surface 3111 and the second wedge-shaped wall surface 4311 can be gradually increased.

[0037] With such a configuration, when the handle 32 is in the reset state, the elastic member 42 provides a driving force for the locking member 43, so that the locking member 43 stably locks the rotating member 31, effectively restricting the rotating member 31, and further restricting the shaking of the handle 32. Even when the handle 32 shakes at a small angle, the contact between the locking member 43 and the rotating member 31 changes. Under the action of the locking elastic member 42, the contact area between the first wedge-shaped wall surface 3111 and the second wedge-shaped wall surface 4311 gradually increases, thereby more advantageously restricting the rotation of the rotating member 31, thereby increasing the locking force of the rotating member 31, and stably locking the handle 32.

[0038] Among them, the rotating member 31 can be a rotating disk, and the matching portion 311 can be a matching groove. The matching groove can penetrate the rotating disk along the thickness direction of the rotating disk, or can not penetrate the rotating disk. The matching groove is gradually narrowed from the locking member 43 to the handle 32.

[0039] Continue to refer to Figures 1 to 5 The housing 1 is provided with a long slide hole 121, that is, the long slide hole 121 is formed at the bottom of the front lock housing 12, and the long slide hole 121 is extended along the thickness direction of the housing 1. The locking piece 43 is provided with a toggle portion 432, and the toggle portion 432 is arranged in the long slide hole 121 and extends to the outside of the housing 1. When the toggle portion 432 is subjected to external force, it drives the locking piece 43 to move along the direction defined by the long slide hole 121, so that the locking piece 43 is switched from a locked state to an unlocked state.

[0040] With such a setting, it is convenient for the user to toggle the toggling part 432, so as to drive the locking convex part 431 of the locking part 43 to disengage from the mating part 311, release the locking of the rotating part 31, and unlock the handle 32. The user can rotate the handle 32 to expose the lock core hole 11 for the user to perform the unlocking and locking operations. The operation method is simple and efficient, which helps to improve the efficiency of unlocking the handle 32.

[0041] The locking assembly 4 further includes a bracket 41 disposed in the housing 1. The bracket 41 is fixedly installed on the inner wall of the housing 1. One end of the elastic member 42 abuts against the bracket 41, and the other end abuts against the locking member 43. The bracket 41 is provided with a guiding portion 411, and the locking member 43 is provided with a guiding portion 433. The guiding portion 433 is in guiding cooperation with the guiding portion 411 to guide and direct the movement of the locking member 43, that is, to guide and direct the locking member 43 to move in the direction defined by the long sliding hole 121. Such a setting helps to improve the convenience of the user's operation, enhance the smoothness of the user toggling the locking member 43, and enhance the user experience.

[0042] Specifically, the guiding portion 411 may be a guiding groove extending along the thickness direction of the bracket 41, and the guiding portion 433 may be a lateral convex block. The lateral convex block is in sliding cooperation with the groove wall of the guiding groove, so as to realize the guiding movement of the locking member 43.

[0043] The groove wall of the guiding groove is penetrated with an avoidance notch for avoiding the locking convex part 431. This can prevent the locking member 43 from interfering and colliding with the bracket 41 during movement. On the one hand, it can well protect the locking member 43 and help to extend the service life of the locking member 43. On the other hand, it can improve the compactness between structures and improve the overall use performance of the handle locking device of the intelligent door lock.

[0044] The locking member 43 is provided with an installation groove 434. The elastic member 42 may be a spring. One end of the spring abuts against the bottom of the guiding groove, and the other end extends into the installation groove 434. In this way, the spring can be stably assembled, ensuring that the spring can stably and elastically press the locking member 43, thereby improving the locking stability of the locking member 43 to the rotating member 31.

[0045] The elastic member 42 may also be other structural members with elastic potential energy, as long as it can provide an elastic force for the locking member 43, and no specific limitation is made here.

[0046] Continue to refer to Figures 1 to 5 , a convex ring 14 is provided in the housing 1. The rotating member 31 is sleeved on the convex ring 14. The handle assembly 3 further includes a reset feedback member 33. The reset feedback member 33 is installed on the rotating member 31 and rotates synchronously with the rotating member 31. The reset feedback member 33 is in feedback cooperation with the housing 1, and the reset feedback member 33 is used to provide a reset state feedback for the handle 32.

[0047] With such a setting, after the handle 32 is reset, the reset feedback member 33 can timely feedback the reset state of the handle 32, so that the user can know the reset state of the handle 32, improving the user experience. In addition, the reset feedback member 33 is slidably engaged with the housing 1, which can also provide an operating feel for the user, further improving the user experience.

[0048] The reset feedback member 33 is a ball catch structure, and the housing 1 is provided with a mating hole 15. The mating hole 15 is arranged on the rotation path of the reset feedback member 33. The ball catch structure is engaged with the mating hole 15 to feedback the reset state of the handle 32. When the handle 32 is reset, the ball of the ball catch structure slides into the mating hole 15 in real time and makes a sound to indicate that the handle 32 is reset in place.

[0049] Furthermore, a plurality of reset feedback members 33 are provided, and the number of mating holes 15 is set corresponding to the number of reset feedback members 33. All the mating holes 15 are spaced apart and distributed on the rotation path of the reset feedback member 33. Through the one-to-one engagement of the plurality of reset feedback members 33 and the plurality of mating holes 15, the user experience can be greatly improved.

[0050] It can be understood that the reset feedback member 33 can also be other structural members with reset feedback, as long as the reset state of the handle 32 is timely feedback, which will not be listed one by one here.

[0051] Continue to refer to Figures 1 to 5 , the convex ring 14 is formed with a through hole 141. The handle 32 is provided with a rotating shaft 321. The rotating shaft 321 extends into the through hole 141. The handle 32 is connected to the rotating member 31 through a connecting member 34. The housing 1 is provided with a limiting arc hole 16 for the connecting member 34 to pass through. The axis of the limiting arc hole 16 coincides with the axis of the convex ring 14. The limiting arc hole 16 is used to limit the rotation angle of the handle 32.

[0052] With such a setting, the rotation angle of the handle 32 is limited by the limiting arc hole 16, which can not only ensure the operating feel but also avoid the possibility of damaging the handle 32 due to large-angle rotation of the handle 32.

[0053] It can be understood that the handle 32 can rotate relative to the housing 1 in the clockwise direction or in the counterclockwise direction.

[0054] Furthermore, two limiting arc holes 16 are provided. The two limiting arc holes 16 are arranged on both sides of the convex ring 14 and are symmetrically arranged with respect to the convex ring 14. The number of connecting members 34 is also correspondingly set to two. The two connecting members 34 pass through the corresponding limiting arc holes 16 one by one. With such a setting, the rotation stability of the handle 32 can be increased to provide a more stable operating feel.

[0055] The connecting member 34 may be a mounting column, one end of which may be integrally formed with the handle 32, and the other end of which may be fixed to the rotating member 31 by screws. The connecting member 34 may also be a latch or other mechanism with connecting properties, which is not specifically limited here.

[0056] The handle 32 can rotate at an angle of 0-45° in a clockwise or counterclockwise direction. For example, the handle 32 can rotate at any angle within a range of 45° in a clockwise direction, and the handle 32 can also rotate at any angle within a range of 45° in a counterclockwise direction to expose the lock core hole 11, making it convenient for the user to insert the key into the lock core hole 11 to unlock the lock.

[0057] Reference Figure 1 The handle locking device of the smart door lock also includes a hole cover 5, which is rotatably connected to the housing 1 and is used to cover or open the lock core hole 11. On the one hand, the hole cover 5 can be used to hide the lock core hole 11 to prevent the lock core hole 11 from being exposed to the outside. On the other hand, the hole cover 5 can prevent dust or foreign matter from entering the lock core hole 11, effectively protecting the lock core assembly 2 and ensuring the performance of the handle locking device of the smart door lock.

[0058] Reference Figures 1 to 5 The unlocking principle of the handle locking device of the smart door lock is as follows:

[0059] Unlocking principle: In the locked state, manually toggle the toggle portion 432 to drive the locking member 43 to overcome the elastic force of the elastic member 42, so that the locking member 43 moves toward the bracket 41, and the locking member 43 exits the matching groove to release the lock of the rotating member 31. At this time, the rotating member 31 is in a free rotation state, and then the handle 32 is turned to reveal the lock core hole 11. The user inserts the key into the lock core hole 11 to perform the unlocking operation;

[0060] Locking principle: In the unlocked state, the handle 32 is returned to its original position, and the rotating member 31 rotates with the handle 32 until there is a clear sense of being in place. The ball of the ball structure pops out and slides into the matching hole 15. At the same time, the locking member 43 slides into the matching groove under the action of the elastic member 42, thereby locking the rotating member 31 and then locking the handle 32. There is no need to manually turn the toggle part 432 again, and the handle 32 can be self-locked.

[0061] The utility model provides a smart door lock, which includes a handle locking device of the smart door lock. The specific structure of the handle locking device of the smart door lock refers to the above embodiments. Since the smart door lock adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
