Description

Technical Field

[0001] The utility model relates to the field of smart locks, in particular to a smart lock. Background Art

[0002] Smart locks generally have two designs: left-opening and right-opening. The clutch blocks used to control the locking and unlocking of the smart locks in these two designs have the same installation orientation, the only difference is that the installation orientation of the handle differs by 180°.

[0003] Because users lack relevant knowledge about locks and are unable to accurately describe their needs, installers often need to carry both left-opening and right-opening smart locks during the door-to-door installation process so that they can choose between them based on actual installation needs at the installation site, causing great inconvenience. Utility Model Content

[0004] Based on this, it is necessary to provide a smart lock to address the problem that the direction of the door opening of the smart lock cannot be switched.

[0008] A handle assembly, wherein the handle assembly is rotatably arranged on the panel around a first rotation axis, the first clutch block is rotatably arranged on the handle assembly around a first rotation axis, the handle assembly comprises a shell and a first clutch member, the first clutch member is movably arranged in the shell, a second boss and a third boss are arranged on the shell, the first boss, the second boss and the third boss are sequentially arranged in the circumferential direction of the first rotation axis; the handle assembly has a left-door-opening state and a right-door-opening state; when the handle assembly is in the right-door-opening state, the first clutch slot and the first clutch member are opposite to each other to allow the first clutch member to at least partially enter the first clutch slot; when the handle assembly is in the left-door-opening state, the second clutch slot and the first clutch member are opposite to each other to allow the first clutch member to at least partially enter the second clutch slot; and

[0009] A reversing assembly is installed on the handle assembly, and the reversing assembly has a limited state and a non-limited state. When the reversing assembly is in the limited state, the reversing assembly is used to limit the rotation of the handle assembly on the panel; when the reversing assembly is in the non-limited state, the handle assembly at least rotates around the first rotation axis on the panel to switch between the left-door-opening state and the right-door-opening state.

[0010] The reversing assembly of the utility model comprises a rotating disk, a torsion spring and a stopper, wherein the rotating disk is fixed on the housing, the rotating disk has a first abutting portion, the torsion spring is sleeved on the housing, the torsion spring has a first end and a second end, and the panel is sequentially provided with a fourth boss, a fifth boss and a sixth boss in the circumferential direction of the first rotation axis, wherein the first end is located between the fifth boss and the sixth boss, and the second end is located between the fourth boss and the fifth boss in the circumferential direction of the first rotation axis;

[0011] When the handle assembly is in the right-opening state and the reversing assembly is in the limiting state, the limiting member is located on the rotating disk, the first end abuts against the limiting member and the sixth boss at the same time, the second end abuts against the fourth boss and the first abutting portion at the same time, and the fifth boss is used to limit the first end and the second end;

[0012] When the handle assembly is in the right-opening state and the reversing assembly is in the non-limiting state, the first end abuts against the sixth boss, the limiting member avoids the first end, and the second end abuts against the fourth boss;

[0013] When the handle assembly is in the left-opening state and the reversing assembly is in the limiting state, the limiting member is located on the rotating disk, the first end abuts against the first abutting portion and the sixth boss at the same time, the second end abuts against the fourth boss and the limiting member at the same time, and the fifth boss is used to limit the first end and the second end;

[0014] When the handle assembly is in a left-open state and the reversing assembly is in a non-limiting state, the first end abuts against the sixth boss, the second end abuts against the fourth boss, and the limiting member avoids the second end.

[0015] In the utility model, at least one of the second boss and the third boss is spaced apart from the first boss.

[0016] The position-limiting member of the utility model is a screw, and the position-limiting member is threadedly connected to the rotating disk.

[0017] According to the utility model, when the handle assembly is in the right-opening state and the reversing assembly is in the limiting state, the second boss contacts the first boss; when the handle assembly is in the left-opening state and the reversing assembly is in the limiting state, the third boss contacts the first boss.

[0018] In the utility model, when the reversing assembly is in a non-limiting state, the first clutch member is located outside the first clutch slot and the second clutch slot.

[0020] In the utility model, at least one of the first clutch groove and the second clutch groove is in a flared shape.

[0021] The handle assembly of the utility model also includes a clutch motor, a transmission shaft, a first spring and a first elastic member. An abutment member is arranged on the outer wall of the transmission shaft. One end of the transmission shaft is transmitted to the clutch motor, and the other end is slidably connected with the first clutch member. The first spring is sleeved on the transmission shaft, and the first elastic member is used to push the first clutch member toward the clutch motor so that the abutment member abuts against the first spring.

[0022] A part of the first clutch block of the utility model is exposed outside the panel and the shell.

[0023] The beneficial effects of the utility model are:

[0024] When the reversing assembly is in a limited state, the reversing assembly can limit the rotation of the handle assembly on the panel. At this time, although the handle assembly can rotate, the rotation angle is limited, which meets the normal locking and unlocking requirements of the handle assembly, but cannot achieve switching between the left door opening state and the right door opening state.

[0025] When the reversing assembly is in a non-limiting state, the handle assembly can push the first boss through the second boss or the third boss to allow the first clutch block to rotate together with the handle assembly. After the handle assembly is rotated into place, the first clutch block is additionally rotated to align the first clutch slot or the second clutch slot with the first clutch component, thereby completing the reversal of the handle assembly while ensuring that the installation direction of the first clutch component does not change.

[0026] The smart lock of the utility model can meet the needs of both left-opening and right-opening doors, has stronger versatility, and can greatly facilitate the on-site installation process of installers. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Embodiment 1:

[0050] See also Figure 1 , Figure 2 , Figure 5 and Fig.10 This embodiment provides a smart lock, including a panel 1, a first clutch block 2, a handle assembly and a reversing assembly.

[0051] The handle assembly is rotatably arranged on the panel 1 around the first rotation axis, wherein the handle assembly has a left-door opening state and a right-door opening state. Figure 2 If the handle assembly can be rotated 180° along direction A or direction B on panel 1, the handle assembly can be switched from the right-opening state to the left-opening state. Similarly, see Figure 5 and Fig.11 If the handle assembly can be rotated 180 degrees along direction A or direction B, the handle assembly can also be switched from the left-opening state to the right-opening state.

[0052] The reversing assembly is installed on the handle assembly, and the reversing assembly has a limit state and a non-limit state. Figure 2 and Figure 5 When the reversing assembly is in the limited position state, the reversing assembly can limit the handle assembly on the panel 1 to limit the rotation angle of the handle assembly along the A direction and the B direction on the panel 1. Accordingly, the handle assembly cannot be switched from the right-opening state to the left-opening state, nor can it be switched from the left-opening state to the right-opening state. On the contrary, when the reversing assembly is in the non-limiting state, the reversing assembly allows the handle assembly to rotate 180° along the A direction and / or the B direction, that is, the handle assembly is allowed to switch between the left-opening state and the right-opening state by rotating around the first rotation axis on the panel 1.

[0053] See also Figure 1 , Figure 3-Figure 5 , Fig.13 and Fig.14 In this embodiment, the first clutch block 2 is generally cylindrical, and the handle assembly includes a housing 31, and an axial hole is provided in the housing 31. The first clutch block 2 passes through the axial hole, so that the first clutch block 2 is rotatably arranged on the handle assembly around the first rotation axis. The two ends of the first clutch block 2 are both located outside the axial hole, one end of the first clutch block 2 is located in the housing 31, and the other end is exposed to the housing 31 and the panel 1, and the rotation of the first clutch block 2 on the housing 31 can be controlled separately through the exposed end. The first clutch groove 21, the first boss 22 and the second clutch groove 23 are provided on the outer wall of the first clutch block 2, and the first clutch groove 21, the first boss 22 and the second clutch groove 23 are all located on the end of the first clutch block 2 in the housing 31, and the first clutch groove 21 and the second clutch groove 23 extend radially along the first rotation axis. The first clutch groove 21, the first boss 22 and the second clutch groove 23 are arranged in sequence and spaced in the circumferential direction of the first rotation axis.

[0054] The handle assembly also includes a first clutch member 32 and a clutch motor 35, both of which are arranged in the housing 31 and can rotate on the panel 1 synchronously with the housing 31. In this embodiment, the first clutch member 32 is generally rod-shaped, and the clutch motor 35 can control the first clutch member 32 to move axially. The housing 31 and the first clutch block 2 can rotate relative to each other so that the first clutch slot 21 or the second clutch slot 23 is relative to the first clutch member 32. The housing 31 is provided with a second boss 33 and a third boss 34, wherein the first boss 22, the second boss 33 and the third boss 34 are arranged in sequence in the circumferential direction of the first rotation axis.

[0055] See also Figure 1 , Figure 3 , Fig.13 and Fig.14When the handle assembly is in the right-opening state, the first clutch slot 21 and the first clutch member 32 are opposite to each other, and the first clutch member 32 can move axially under the control of the clutch motor 35, so that the end of the first clutch member 32 can enter and exit the first clutch slot 21. Figure 5 On the contrary, when the handle assembly is in the left-opening state, the second clutch slot 23 and the first clutch member 32 are relative to each other, and the first clutch member 32 can move axially under the control of the clutch motor 35, so that the end of the first clutch member 32 can enter and exit the second clutch slot 23.

[0056] In the process of the handle assembly switching between the right-opening state and the left-opening state in this embodiment, the first clutch member 32 is always in a retracted state to prevent the first clutch member 32 from entering the first clutch slot 21 and the second clutch slot 23, that is, when the reversing assembly is in a non-limiting state, the first clutch member 32 is located outside the first clutch slot 21 and the second clutch slot 23. In addition, it should be noted that the switching of the handle assembly between the right-opening state and the left-opening state at least requires the rotation of the handle assembly on the panel 1.

[0057] See also Figure 3-Figure 5 The general process of switching the handle assembly from the right-opening state to the left-opening state in this embodiment is as follows: first, adjust the reversing assembly to the non-limiting state, and rotate the first clutch block 2 alone (operate through the end of the first clutch block 2 exposed to the housing 31 and the panel 1), so that the second boss 33 contacts the first boss 22, and then rotate the housing 31 along the A direction, so that the second boss 33 pushes the first boss 22, so that the first clutch block 2 also rotates synchronously with the housing 31, and after the housing 31 rotates 180°, the first clutch block 2 is rotated 180° along the A direction alone, so that the installation direction of the first clutch block 2 is reset, and the first boss 22 contacts the third boss 34. Finally, the reversing assembly is readjusted to the limiting state, and the smart lock can be installed and used normally.

[0058] Conversely, if the handle assembly needs to be switched from the left-opening state to the right-opening state, the reversing assembly also needs to be adjusted to the non-limiting state first, and then the housing 31 is rotated in the B direction, the third boss 34 pushes the first boss 22, and the first clutch block 2 and the housing 31 are synchronously rotated 180°, and then the first clutch block 2 is rotated 180° in the B direction alone, so that the second boss 33 and the first boss 22 are re-contacted. Finally, the reversing assembly is readjusted to the limiting state, and the smart lock can be installed and used normally.

[0059] In this embodiment, when the handle assembly is in the left-door opening state and the right-door opening state, the first boss 22 is in contact with one of the second boss 33 and the third boss 34, and is separated from the other. In some other embodiments, when the handle assembly is in the left-door opening state and the right-door opening state, the second boss 33 and the third boss 34 can be separated from the first boss 22, and one of the second boss 33 and the third boss 34 can be brought into contact with the first boss 22 by rotating the housing 31.

[0060] See also Figure 6-Figure 12 The reversing assembly of this embodiment includes a rotating disk 41, a torsion spring 42 and a stopper 43. The rotating disk 41 is fixed on the housing 31 and is located outside the housing 31, so that the rotating disk 41 can rotate synchronously with the housing 31 around the first rotation axis, wherein the first rotation axis is located at the center of the rotating disk 41. The rotating disk 41 has a first abutment portion 411, and the rotating disk 41 and the panel 1 are spaced apart so that the torsion spring 42 is sleeved on the housing 31 and is located between the panel 1 and the rotating disk 41.

[0061] The panel 1 is provided with a fourth boss 11, a fifth boss 12 and a sixth boss 13 in sequence in the circumferential direction of the first rotation axis, and the torsion spring 42 has a first end 421 and a second end 422, wherein, in the circumferential direction of the first rotation axis, the first end 421 is located between the fifth boss 12 and the sixth boss 13, and the second end 422 is located between the fourth boss 11 and the fifth boss 12. The stopper 43 is movably arranged or detachably arranged on the turntable 41, so as to change the relative position of the stopper 43 and the turntable 41. For example, the stopper 43 is selected as a screw, and the stopper 43 is threadedly connected to the turntable 41.

[0062] See Figure 6-Figure 9At this time, the handle assembly is in the right-opening state and the reversing assembly is in the limiting state. The limiting member 43 is located on the rotating disk 41, and the first end 421 abuts against the limiting member 43 and the sixth boss 13 at the same time, and the second end 422 abuts against the fourth boss 11 and the first abutting portion 411 at the same time. In the circumferential direction of the first rotating shaft, the first end 421 and the second end 422 are located between the limiting member 43 and the first abutting portion 411. If the housing 31 is rotated along the A direction, the limiting member 43 will push the first end 421 to turn to the fifth boss 12. At this time, the first end 421 will separate from the sixth boss 13, while the second end 422 still abuts against the fourth boss 11, and the first abutting portion 411 will separate from the second end 422. Until the first end 421 abuts against the fifth boss 12, the rotating disk 41 and the housing 31 cannot be further rotated along the A direction, and accordingly, the housing 31 cannot be rotated 180° along the A direction. Similarly, if the housing 31 is rotated along the B direction, the first abutting portion 411 will push the second end 422 toward the fifth boss 12, and the second end 422 will be separated from the fourth boss 11, and the limiting member 43 will also be separated from the first end 421, but the first end 421 will still abut on the sixth boss 13. When the second end 422 abuts on the fifth boss 12, the housing 31 cannot be further rotated along the B direction, so the housing 31 cannot be rotated 180° along the B direction. Therefore, when the reversing assembly is in the limited state, the handle assembly cannot be switched from the right-opening state to the left-opening state.

[0063] See also Figure 6-Figure 9 In this embodiment, the switching assembly can be switched to the non-limiting state only by loosening or removing the limiting member 43. After the switching assembly is switched to the non-limiting state, the first end 421 still abuts against the sixth boss 13, but the limiting member 43 avoids the first end 421 and separates from the first end 421, and the second end 422 also abuts against the fourth boss 11 and the first abutting portion 411 at the same time. At this time, if the housing 31 is rotated along the B direction, the fifth boss 12 will still limit the second end 422, so the handle assembly still cannot be switched from the right-opening state to the left-opening state by rotating along the B direction. However, if the housing 31 is rotated in the direction A, the first end 421 remains in contact with the sixth boss 13 due to the avoidance effect of the stopper 43 on the first end 421, and the turntable 41 loses interference with the first end 421. At the same time, the first contact portion 411 is separated from the second end 422, and the second end 422 is still in contact with the fourth boss 11. The rotation of the turntable 41 in the direction A will not be restricted by the fifth boss 12, so the housing 31 and the turntable 41 can be rotated 180° in the direction A to allow the handle assembly to switch from the right-opening state to the left-opening state. Fig.12 When the housing 31 and the turntable 41 rotate 180°, the first abutting portion 411 is located at the sixth boss 13, and then the limiting member 43 is reinstalled or tightened to switch the reversing assembly to the limited state.

[0064] See Figure 10-12 When the handle assembly is in the left-open state and the reversing assembly is in the limited state, the limited member 43 is located on the rotating disk 41, the second end 422 abuts against the fourth boss 11 and the limited member 43 at the same time, the first end 421 abuts against the first abutting portion 411 and the sixth boss 13 at the same time, and in the circumferential direction of the first rotating shaft, the first end 421 and the second end 422 are located between the limited member 43 and the first abutting portion 411. Similar to the above, at this time, whether the housing 31 rotates in the A direction or the B direction, the fifth boss 12 will eventually play a limiting role, resulting in the handle assembly being unable to switch from the left-open state to the right-open state.

[0065] See again Figure 10-12 After the limiting member 43 is loosened or removed, the reversing assembly is in the non-limiting state again. The first end 421 abuts against the sixth boss 13 and the first abutting portion 411, and the second end 422 only abuts against the fourth boss 11, and the limiting member 43 avoids the second end 422. If the housing 31 is rotated along the A direction, the handle assembly cannot be switched from the left-open door state to the right-open door state. If the housing 31 is rotated along the B direction, the housing 31 can be rotated 180° to allow the handle assembly to switch from the left-open door state to the right-open door state.

[0066] See also Figure 13-14 At this time, the handle assembly is in the right-opening state. If the reversing assembly is in the limited position, the housing 31 can rotate along the A direction or the B direction. Based on the above analysis, it can be seen that the rotation angle of the housing 31 is limited at this time. In addition, the second boss 33 is in contact with the first boss 22. Fig.13 When the end of the first clutch member 32 enters the first clutch slot 21, the first clutch block 2 and the handle assembly are in a state of being able to rotate synchronously. If the handle assembly rotates along direction A, it can drive the first clutch block 2 to rotate synchronously along direction A to achieve the purpose of locking. Conversely, if the handle assembly rotates along direction B, it can drive the first clutch block 2 to rotate synchronously along direction B to achieve the purpose of unlocking. Fig.14 When the end of the first clutch member 32 leaves the first clutch groove 21, if the handle assembly rotates along the B direction, the first clutch block 2 will not rotate relative to the panel 1, and the second boss 33 will separate from the first boss 22, so the handle assembly is in an idling state and cannot be unlocked.

[0067] See also Figure 5, at this time, the handle assembly is in the left-opening state. If the reversing assembly is in the limited position state, the housing 31 can also rotate in the A direction or the B direction, and the rotatable angle of the housing 31 is limited. At this time, the third boss 34 contacts the first boss 22. Similarly, when the end of the first clutch member 32 enters the second clutch slot 23, the first clutch block 2 and the handle assembly are in a state where they can rotate synchronously. If the handle assembly rotates in the A direction, it can drive the first clutch block 2 to rotate synchronously in the A direction to achieve the purpose of unlocking. Conversely, if the handle assembly rotates in the B direction, it can drive the first clutch block 2 to rotate synchronously in the B direction to achieve the purpose of locking. When the end of the first clutch member 32 leaves the second clutch slot 23, if the handle assembly rotates in the A direction, the first clutch block 2 will not rotate relative to the panel 1, and the third boss 34 will separate from the first boss 22, so the handle assembly is in an idling state and cannot be unlocked.

[0068] In this embodiment, the first clutch slot 21 and the second clutch slot 23 both extend radially along the first rotation axis, and the extension directions of the first clutch slot 21 and the second clutch slot 23 are located on the same straight line. In order to facilitate the end of the first clutch member 32 to enter and exit the first clutch slot 21 and the second clutch slot 23, the first clutch slot 21 and the second clutch slot 23 are both flared.

[0069] This embodiment also provides a specific structure for the clutch motor 35 to control the axial movement of the first clutch member 32. The handle assembly further includes a transmission shaft 36, a first spring 37 and a first elastic member 38, and the first elastic member 38 can also be a spring. One end of the transmission shaft 36 is transmitted to the clutch motor 35, and the clutch motor 35 controls the rotation of the transmission shaft 36. The other end of the transmission shaft 36 is slidably connected with the first clutch member 32 so that the first clutch member 32 can slide relative to the transmission shaft 36. One end of the first elastic member 38 abuts against the inner wall of the housing 31, and the other end abuts against the first clutch member 32 to push the first clutch member 32 toward the clutch motor 35. The first spring 37 is sleeved on the transmission shaft 36, wherein an abutment member 361 is provided on the outer wall of the transmission shaft 36, and under the pushing action of the first elastic member 38, the abutment member 361 abuts against the first spring 37. It is understandable that the first spring 37 itself extends in a spiral shape, so as the abutment member 361 rotates, the first spring 37 will move in the axial direction of the transmission shaft 36, and then cooperate with the first elastic member 38 to cause the first clutch member 32 to move axially.

[0070] The technical features of the above-described embodiments may be arbitrarily combined.
