The terms "first", "second", etc. in the description and claims of the present utility model or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order.

[0026] Referring to "embodiments" in the present utility model means that the specific features, structures or characteristics described in connection with the embodiments may be included in at least one embodiment of the present utility model. The phrase appears in various positions in the description does not necessarily refer to the same embodiment, nor is it an exclusive, independent or alternative embodiment to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described in the present utility model may be combined with other embodiments.

[0027] In order to enable those skilled in the technical field to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Such as Figure 1-7As shown in the figure, the present utility model relates to an intelligent door lock with a clutch unlocking structure, which includes a front panel 1, a lock body 2, and a rear panel 3 arranged in sequence from front to back. A square shaft hole 2011 and a lock core hole 202 are provided on the lock body 2. A square shaft 201 is arranged in the square shaft hole 2011. A first controller component, an automatic unlocking component, and a key unlocking component are arranged in the front panel 1. One end of the square shaft 201 close to the front panel 1 is fixedly provided with a clutch rotating shaft gear 4. The key unlocking component includes a lifting clutch push plate 51 and a lifting lock core 52. The upper and lower ends of the lifting clutch push plate 51 are respectively a clutch driving part and a lifting connecting part. The automatic unlocking component includes an unlocking driving device 61 and an unlocking clutch driving part.

[0029] Through the setting of the lifting lock core 52, after the key 7 is inserted into the lifting lock core 52 and rotated, it can push the clutch driving part to perform a lifting movement, realizing the connection or separation between the clutch driving part and the clutch rotating shaft gear 4, and the clutch driving part can effectively drive the clutch rotating shaft gear 4 to rotate, thereby realizing unlocking with the key 7.

[0030] And adopting this structure, in the separated state of the clutch driving part and the clutch rotating shaft gear 4, it can ensure that when the user uses electric automatic unlocking, it will not affect the automatic unlocking component.

[0031] Through the setting of the unlocking driving device 61, it can effectively drive the unlocking clutch driving part to be connected or separated from the clutch rotating shaft gear 4, and the unlocking clutch driving part can drive the clutch rotating shaft gear 4 to rotate, thereby realizing electric automatic unlocking.

[0032] Through the setting of the unlocking clutch driving part, when the unlocking clutch driving part is in a separated state from the clutch rotating shaft gear 4 and the user uses the key 7 to unlock, it will not affect the key unlocking component.

[0033] By both the automatic unlocking component and the key unlocking component acting on the square shaft 201 and independently driving the square shaft 201 to rotate, thereby controlling the retraction and extension of the lock tongue in the lock body 2, it avoids the situation in the traditional structure where key unlocking and electric automatic unlocking in the front and rear panels 3 act on the square shaft 201 and the lock core hole 202 respectively. For different models of the lock body 2, the positions of the lock core holes 202 on the lock body 2 are different, while the position of the square shaft 201 is relatively fixed. This enables the front and rear panels 3 to be compatible with different models of the lock body 2, effectively improving the compatibility of the front panel 1 and the rear panel 3 with multiple models of the lock body 2. This structural device is suitable for 95% of the double-live double-fast broken bridge aluminum lock bodies 2 (2885, 3085, 3585, etc.) on the market, making the use and installation more flexible and enhancing the competitiveness of the product.

[0034] The clutch driving part is the driving rack 511 and the clutch clearance position 512 arranged on the lifting clutch push plate 51. The driving rack 511 can be meshed and connected with the clutch rotating shaft gear 4, and the lifting clutch push plate 51 can avoid being affected by the operation of the automatic unlocking component in the initial state through the clutch clearance position 512.

[0035] Through the setting of the clearance groove, the clutch rotating shaft gear 4 is not restricted by the driving rack 511 of the lifting clutch push plate 51, avoiding interference between the automatic unlocking component and the key unlocking component.

[0036] The user rotates the lifting lock core 52 through the key 7 to drive the lifting clutch push plate 51 to move up and down, so that the clutch rotating shaft gear 4 switches back and forth between two mating positions: cooperating with the driving rack 511 and being arranged at the clutch clearance position 512.

[0037] The number of the driving racks 511 is two groups, and the two groups of driving racks 511 are symmetrically arranged on the upper and lower sides of the clutch clearance position 512 respectively.

[0038] Through the setting of the two groups of driving racks 511, it is convenient to adapt to different lock bodies 2 of different models or different installation methods, adapt to different unlocking directions, and meet the scenarios of unlocking with the lower driving rack 511 or the upper driving rack 511.

[0039] The intelligent door lock with a clutch unlocking structure further includes a clutch gear reset part 8. The automatic unlocking component further includes a gear set. The unlocking clutch driving part is a clutch driving gear 9. The moving end of the unlocking driving device 61 is connected to one end of the gear set, and the other end of the gear set is meshed and connected with the clutch driving gear 9. A positioning block 41 is arranged on the clutch rotating shaft gear 4, and an arc-shaped clutch groove 91 is arranged on the clutch driving gear 9. The positioning block 41 is arranged in the arc-shaped clutch groove 91. The clutch gear reset part 8 is a reset spring. Elastic reset feet 81 are arranged at both ends of the reset spring respectively. The two groups of elastic reset feet 81 are arranged on both sides of the positioning block 41 respectively. And a spring placement position 101 for cooperating with the reset spring is arranged on the automatic unlocking component. A spring fixing block 102 is arranged in the spring placement position 101. The two groups of elastic reset feet 81 are also arranged on both sides of the spring fixing block 102 respectively. The clutch rotating shaft gear 4 can be reset through the cooperation of the spring fixing block 102 and the elastic reset feet 81.

[0040] Through the setting of the clutch gear reset part 8, after the unlocking driving device 61 drives the clutch driving gear 9 to drive the clutch rotating shaft gear 4 to rotate, when the unlocking driving device 61 drives the clutch driving gear 9 to reset, the clutch rotating shaft gear 4 can also be reset under the action of the reset spring. After resetting, it is ensured that the key unlocking component is not affected by the automatic unlocking component when unlocking, improving the user experience.

[0041] And the clutch gear reset member 8, after the key 7 rotates to lift the lock cylinder 52 and controls the retraction of the lock tongue through the driving rack 511, when the key 7 is released, under the action of the clutch secondary gear reset member, it will still control the rotation and reset of the clutch rotating shaft gear 4, so that the clutch rotating shaft gear 4 is arranged in the clutch avoidance position 512, realizing the reset of the key unlocking assembly.

[0042] A gear housing 10 is sleeved outside the gear set, and a spring placement position 101 is arranged on the inner wall of the gear housing 10.

[0043] Through the setting of the spring fixing block 102, when the clutch rotating shaft gear 4 rotates, the positioning block 41 pushes one side of the elastic reset foot 81 to deform elastically according to the rotation direction, and the other side of the elastic reset foot 81 abuts against the fixing block, so as to produce the effect of reset elastic force.

[0044] Obviously, for the unlocking clutch driving member being the clutch driving gear 9, the automatic unlocking assembly further includes a gear set, realizing that the automatic unlocking assembly controls the rotation of the clutch rotating shaft gear 4 in a clutch manner. Other structures can also be used for replacement. For example, the automatic unlocking assembly includes an unlocking driving device 61 and a lifting clutch push plate 51. The upper and lower ends of the lifting clutch push plate 51 are respectively a clutch driving part and a lifting connecting part.

The unlocking driving device 61 can drive the lifting clutch push plate 51 to move up and down. The clutch driving part is a driving rack 511 and a clutch avoidance position 512 arranged on the lifting clutch push plate 51. The driving rack 511 can be meshed and connected with the clutch rotating shaft gear 4. The lifting clutch push plates 51 of the automatic unlocking assembly and the key unlocking assembly act on both sides of the clutch rotating shaft gear 4 respectively, and can also achieve the effect of the above solution.

[0045] A rotating shaft hole cooperating with the clutch rotating shaft gear 4 is arranged on the clutch driving gear 9. The clutch rotating shaft gear 4 includes a rotating shaft part and a gear part 42. The square shaft 201 is fixedly arranged in the rotating shaft part, and the rotating shaft part is arranged in the rotating shaft hole. The gear part 42 is arranged on the side of the clutch rotating shaft gear 4 away from the lock body 2.

[0046] By arranging the gear part 42 on the side of the clutch rotating shaft gear 4 away from the lock body 2, the working process can be more stable.

[0047] The gear set includes a driving wheel 11 and a driven wheel 12. The driving wheel 11 is meshed and connected with the driven wheel 12. The driven wheel 12 is meshed with the clutch driving gear 9. The unlocking driving device 61 is a driving motor and a worm assembly. The moving end of the driving motor is connected with one end of the worm assembly. The worm assembly is meshed with the driving wheel 11.

[0048] The intelligent door lock with a clutch unlocking structure further includes a gear rotation detection plate 13. A Hall switch is provided on the gear rotation detection plate 13, and a plurality of induction magnets 14 are arranged on the clutch driving gear 9 at an angular interval. Through the cooperation of the Hall switch and the induction magnets 14, the rotation signal of the clutch driving gear 9 can be effectively obtained, and the process of electronic automatic unlocking can be realized more efficiently.

[0049] The number of key unlocking components is two groups. The two groups of key unlocking components are the front key unlocking component and the rear key unlocking component 15 respectively. A second controller component and a battery box component 16 are arranged inside the rear panel 3. The front key unlocking component and the rear key unlocking component 15 are respectively arranged in the front panel 1 and the rear panel 3. The second controller component is electrically connected to the first controller component, and the battery box component 16 is electrically connected to the second controller component. A rear driving gear is arranged at one end of the square shaft 201 facing the rear panel 3. The lifting lock core 52 of the rear key unlocking component 15 can push the clutch driving part to move up and down to be connected or separated from the rear driving gear, and the clutch driving part of the rear key unlocking component 15 can drive the rear driving gear to rotate.

[0050] The clutch driving part of the rear panel 3 is also provided with a clutch avoiding position 512, so that the unlocking of the front panel 1 is not affected by the key unlocking component of the rear panel 3.

[0051] The second controller component includes a second control board 17, a second touch button board 18 and a second fingerprint control 19. A rear swing handle 20 is arranged on the rear panel 3.

[0054] Through the settings of the first touch button board 22 and the first fingerprint control 23, the front panel 1 can be provided with options for fingerprint electronic automatic unlocking and button password input electronic automatic unlocking.

[0055] The working process of the intelligent door lock with a clutch unlocking structure provided in this embodiment is as follows: The embodiment of the present invention provides an intelligent door lock that has the advantage of higher compatibility with the lock body 2 compared with the existing intelligent door locks.

[0056] For the electronic automatic unlocking process of the front panel 1:

[0057] In the initial state, the lock tongue of the lock body 2 is in the locked state. First, the user selects button password unlocking or fingerprint unlocking on the front panel 1 or the rear panel 3.

[0058] After successful unlocking, the moving end of the unlocking drive device 61 rotates 90 degrees clockwise. The gear set rotates under the drive of the unlocking drive device 61. After the gear set drives the clutch drive gear 9 to rotate 45 degrees, it continues to drive the clutch drive gear 9 for another 45 degrees. When the rotation is greater than 45 degrees, the arc-shaped clutch groove 91 will push the positioning block 41 to rotate together, so that the final clutch shaft gear 4 rotates 45 degrees, and the square shaft 201 controls the lock tongue to contract to achieve unlocking.

[0059] While the positioning block 41 is being pushed, one of the elastic reset feet 81 of the reset spring deforms, providing the reset elastic force for the subsequent reset of the clutch shaft gear 4.

[0060] During the rotation of the clutch drive gear 9, the gear rotation detection plate 13 continuously reads the rotation angle and stops rotating after rotating 90 degrees.

[0061] After 5 seconds, control the moving end of the unlocking drive device 61 to rotate 90 degrees counterclockwise for reset, control the gear set and the clutch drive gear 9 to perform angle reset, so that the end of the arc-shaped clutch groove 91 is far away from the positioning block 41. The positioning block 41 is reset under the action of the reset spring. When the reset is completed, the positioning block 41 is set at the center of the arc-shaped clutch groove 91. At this time, the lock tongue of the lock body 2 extends to achieve the locking process. The arc angle of the arc-shaped clutch groove 91 is 90 degrees.

[0062] For the key 7 unlocking process of the front panel 1:

[0063] In the initial state, the lock tongue of the lock body 2 is in the locked state, and the clutch shaft gear 4 is set in the clutch avoidance position 512. First, the user inserts the key 7 into the lifting lock core 52 and rotates the lifting lock core 52 clockwise. The moving end of the lifting lock core 52 pulls the lifting clutch push plate 51 downward. The upper drive rack 511 moves downward and gradually meshes with the clutch shaft gear 4, driving the clutch shaft gear 4 to rotate. At the same time, when the clutch shaft gear 4 rotates, the positioning block 41 pushes one of the elastic reset feet 81 of the reset spring, causing the elastic reset foot 81 to deform, providing the reset elastic force for the subsequent reset of the clutch shaft gear 4.

[0064] When the user rotates 90 degrees clockwise, the lock tongue of the lock body 2 is completely retracted, completing the unlocking process.

[0065] After completing the unlocking process, the user can directly release their hand or rotate the lifting lock cylinder 52 counterclockwise. In the case of directly releasing the hand, the return spring will control the clutch rotating shaft gear 4 to rotate in the opposite direction, and at the same time drive the lifting clutch push plate 51 to move upward, so that the clutch rotating shaft gear 4 moves away from the driving rack 511 and is arranged in the clutch avoidance position 512. The lock tongue of the lock body 2 also fully extends to complete the locking process.

[0066] In the case of rotating the lifting lock cylinder 52 counterclockwise, it is to control the lifting clutch push plate 51 to move upward, so that the clutch rotating shaft gear 4 moves away from the driving rack 511 and is arranged in the clutch avoidance position 512. The lock tongue of the lock body 2 also fully extends to complete the locking process.

[0067] The unlocking method of the key 7 on the rear panel 3 is the same as that on the front panel 1, which will not be elaborated here.

[0068] As can be seen from the above, the beneficial effects of the present utility model are as follows: By adopting its mechanism, it can effectively solve the problems in the prior art that the flexibility of intelligent door locks in adapting to different lock bodies 2 is poor, there is a problem that they cannot adapt to different lock bodies 2, and the economic benefits are low. By using the product structure, both the key unlocking component and the automatic unlocking component act on the square shaft 201 in the lock body 2, which can flexibly adapt to different models of lock bodies 2, improve the economic benefits of the product and the user experience, and is conducive to improving the competitiveness of the product.

[0069] The above-mentioned specific implementation manner is the preferred implementation manner of the present utility model, and does not limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to this specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
