Description

Technical Field

[0001] This utility model belongs to the field of door handle technology, and in particular relates to a handle assembly and its intelligent door lock. Background Technology

[0002] A smart door lock is a product that combines electronic technology, integrated circuit design, a large number of electronic components, and a variety of innovative recognition technologies.

[0003] Smart door locks typically consist of a front panel, a back panel, and a lock body. The front panel usually houses a handle rotation mechanism for opening and closing the door. Pressing down on the handle rotates a drive shaft, causing the bolt to retract and unlocking the door. Releasing the handle causes it to automatically return to its original position under the action of a return spring, reversing the drive shaft and extending the bolt. The handle rotation mechanism of a smart door lock also usually integrates a fingerprint module for unlocking. The fingerprint module connects to the controller on the panel via a fingerprint cable passing through the handle rotation assembly. Once the controller confirms the fingerprint, the smart door lock can unlock either through the controller or by pressing down on the handle.

[0004] However, the current smart door lock handle turning mechanism on the market faces the following problems:

[0005] 1. When the handle rotation mechanism is turned, the fingerprint connection cable may have problems such as twisting, scraping, or breaking, causing the fingerprint module to malfunction and the door lock to be unable to open;

[0006] 2. The handle rotation mechanism is stuck, causing the handle body to be unable to return to its original position freely up and down;

[0007] 3. The handle rotation mechanism has a short service life and cannot meet high-quality standards.

[0008] Therefore, in view of the above-mentioned technical problems, this utility model provides a handle assembly in which the fingerprint connection wire is arranged between the inner bottom of the handle cover and the bottom of the handle rotating assembly. When the handle body is rotated, the fingerprint connection wire only moves at the bottom of the handle rotating assembly, which can avoid the problems of wire twisting, wire scratching, and wire breakage, thereby solving one or more of the above-mentioned problems.

[0044] like Figure 1-12As shown, an embodiment of this utility model provides a handle assembly, including a handle body 1 and a middle frame 2. A fingerprint module 3 is installed inside the handle body 1, and the fingerprint module 3 is connected to a fingerprint connecting line 4. A clearance groove 5 and a connecting groove 6 are provided at the front end of the handle body 1. The clearance groove 5 is located on one side of the connecting groove 6. The fingerprint connecting line 4 is led out from the clearance groove 5 and passes through the front end of the handle body 1. A guide groove 7 is provided on the clearance groove 5 to guide the fingerprint connecting line 4 out of the clearance groove 5. A handle rotating assembly 8 is installed inside the middle frame 2. The handle rotating assembly 8 includes a rotating shaft 9. The rotating shaft 9 is installed in the connecting groove 6 and is fastened by a fastener 10. A handle cover 11 is provided on the outer side of the middle frame 2. The handle cover 11 closes the handle rotating assembly 8 inside the middle frame 2 and is sleeved onto the front end of the handle body 1. The fingerprint connecting line 4 is located between the inner bottom of the handle cover 11 and the bottom of the handle rotating assembly 8. An opening groove 12 is provided on one side of the handle cover 11, and the fingerprint connecting line 4 passes through the opening groove 12 to exit the handle cover 11. By arranging the fingerprint connection line 4 between the bottom of the handle cover 11 and the bottom of the handle rotation assembly 8, the handle assembly ensures that when the handle body 1 is rotated, the fingerprint connection line 4 only moves at the bottom of the handle rotation assembly 8, thus avoiding problems such as wire twisting, scraping, and breakage, and preventing the smart door lock from failing due to the failure of the fingerprint module 3.

[0045] Specifically, such as Figure 3 , 6As shown in Figures 11 and 12, in this embodiment, the handle body 1 has an L-shaped structure. The handle body 1 is preferably made of aluminum alloy. The rear end of the handle body 1 is used by the user to grip and operate the unlocking action. The front end of the handle body 1 is fitted with a rotating shaft 9 to output torque. An internal cavity 13 is formed within the handle body 1, and a fingerprint module 3 is installed within the cavity 13. The fingerprint module 3 is used to collect the user's fingerprint and transmit the signal to the smart lock controller via a fingerprint connection cable 4. More specifically, the fingerprint connection cable 4 is a flexible flat cable or wire harness. One end of the fingerprint connection cable 4 is connected to the fingerprint module 3, and the other end extends towards the front end of the handle body 1, passes through the handle body 1, and finally connects to the controller. Furthermore, to enable the handle body 1 to output torque, a connecting groove 6 is provided at the front end of the handle body 1. The connecting groove 6 is typically a rectangular groove. After the rotating shaft 9 is inserted into the connecting groove 6, it is tightened by a fastener 10, preferably a stud. The torque on the handle body 1 can be transmitted to the rotating shaft 9 through the connecting groove 6, thus realizing the torque output of the handle body 1. Furthermore, to facilitate the fingerprint connection line 4 passing through the handle body 1, a clearance groove 5 is provided on one side of the connecting groove 6. The clearance groove 5 passes through the front end of the handle body 1, and the fingerprint connection line 4 is led out from the clearance groove 5 and passes through the handle body 1. Preferably, the clearance groove 5 and the connecting groove 6 are integrated, and when the rotating shaft 9 is tightly installed in the connecting groove 6, the rotating shaft 9 cannot contact the fingerprint connection line 4, thereby ensuring that the fingerprint connection line 4 will not experience any kinking or scratching problems. Furthermore, to guide the installation of the fingerprint connection line 4, a guide groove 7 is provided on the upper side of the clearance groove 5. The guide groove 7 is opened at the upper end of the clearance groove 5. When the fingerprint connection line 4 passes through the handle body 1, the guide groove 7 guides the fingerprint connection line 4 to pass through the handle body 1 from the side of the clearance groove 5 and is located outside the rotating shaft 9, so that the fingerprint connection line 4 bypasses the connecting groove 6 and the rotating shaft 9, preventing the rotating shaft 9 from kinking when the handle body 1 rotates.

[0046] Furthermore, such as Figure 1-3As shown, in this embodiment, the middle frame 2 is a plate structure with folded edges, and its cross-section is U-shaped. The middle frame 2 is preferably made of steel plate by stamping to improve its strength and extend its service life. A handle rotating assembly 8 is installed inside the middle frame 2, and a handle cover 11 is disposed on the rear side of the middle frame 2. The handle cover 11 is a cover structure and can be integrally injection molded from plastic material. The handle cover 11 encapsulates the handle rotating assembly 8 within the middle frame 2. The handle rotating assembly 8 includes a rotating shaft 9, which is preferably made of steel. The rotating shaft 9 is tightly inserted into the connecting groove 6 and can be connected to the latch or latch mechanism of the smart lock. Rotating the handle body 1 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the latch or latch mechanism to achieve the unlocking action. Furthermore, a step seat 14 is provided at the front end of the handle body 1, and the handle cover 11 is fitted onto the step seat 14. The handle cover 11 can be fastened to the middle frame 2 by screws. The middle frame 2 is usually firmly installed on the door panel, so that the handle body 1 can rotate relative to the handle cover 11, realizing the unlocking function of the handle body 1. In particular, in this embodiment, the handle cover 11 is fitted onto the rotating shaft 9, the guide groove 7 is located inside the handle cover 11, the handle rotating assembly 8 is installed inside the middle frame 2, and a sufficient receiving cavity 43 is reserved between the handle rotating assembly 8 and the handle cover 11 to accommodate the fingerprint connecting line 4. That is, the fingerprint connecting line 4 is located between the inner bottom of the handle cover 11 and the bottom of the handle rotating assembly 8. The receiving cavity 43 also serves as the moving space for the fingerprint connecting line 4. When the handle body 1 is rotated, the fingerprint connecting line 4 can move within the receiving cavity 43 without contacting the rotating shaft 9, which has a good anti-hinging effect. Furthermore, in order to connect one end of the fingerprint connection line 4 housed in the receiving cavity 43 to the controller of the smart door lock, an opening slot 12 is opened on one side of the handle cover 11. The fingerprint connection line 4 can pass through the opening slot 12 to pass through the handle cover 11 and finally connect to the controller. After the controller receives the fingerprint information from the fingerprint module 3 and compares it, it confirms whether the unlocking can be performed. If the fingerprint does not match, the controller controls the bolt mechanism to lock, and the handle body 1 cannot be rotated.

[0047] Furthermore, such as Figure 3-12As shown, in this embodiment, the handle rotation assembly 8 further includes a base 15, a torsion spring 16, a bushing 17, a claw 18, a retaining spring 19, and a reversing pin 20. The front end of the rotating shaft 9 is provided with a mounting base 21 and a first retaining groove 22. The base 15 is fitted onto the mounting base 21 and is securely connected to the middle frame 2. The bushing 17 is fitted onto the mounting base 21 and presses against the base 15. The torsion spring 16 is fitted onto the bushing 17. The claw 18 is fitted onto the mounting base 21 and presses against the bushing 17. The claw 18 engages with the rotating shaft 9. The retaining spring 19 is engaged with the first retaining groove 22 and presses against the claw 18. The reversing pin 20 is installed at one end of the claw 18, and a retaining pawl 23 is provided at the other end of the claw 18. The reversing pin 20 and the retaining pawl 23 respectively abut against both ends of the torsion spring 16. Specifically, to solve the jamming problem of conventional handle mechanisms, the handle rotation assembly 8 is configured to include a rotating shaft 9, a base 15, a torsion spring 16, a bushing 17, and a claw 18. When the handle body 1 is rotated, the rotating shaft 9 simultaneously transmits torque to the torsion spring 16 through the claw 18, generating a strong rebound force on the torsion spring 16. When the handle body 1 is released, the handle body 1 quickly returns to its original position without jamming under the rebound force of the torsion spring 16. More specifically, the base 15 has a shell structure, typically made of stamped steel plate, which has high strength. The base 15 serves as the carrier for accessories such as the torsion spring 16 and the claw 18, and is fastened to the rear side of the middle frame 2 by screws. To install accessories such as the base 15, torsion spring 16, and claw 18, a mounting base 21 and a first slot 22 are provided on the rotating shaft 9. The mounting base 21 is located at the front end of the rotating shaft 9, and the first slot 22 is located on the front side of the mounting base 21. First, the base 15 is fitted onto the mounting base 21, allowing the rotating shaft 9 to rotate relative to the base 15. Then, the bushing 17 is fitted onto the mounting base 21 and pressed against the base 15. The bushing 17 is installed by engaging with the limiting groove 45 on the base 15 through the limiting protrusion 44 on the bushing 17. The retaining spring 19 is directly fitted onto the outer periphery of the bushing 17. Then, the claw 18 is fitted onto the mounting base 21 and pressed against the bushing 17. The claw 18 is also engaged with the rotating shaft 9, enabling torque transmission between the rotating shaft 9 and the claw 18. Finally, the retaining spring 19 is engaged with the first slot 22, pressing the claw 18. This makes the handle rotating assembly 8 compact and extends its service life.

[0048] Furthermore, such as Figure 3 , 8As shown in Figures 11 and 12, in this embodiment, the claw 18 is a stamped steel plate, and the torsion spring 16 is a helical spring. The two ends of the torsion spring 16 abut against the claw 18. More specifically, a pawl 23 is provided on one side of the claw 18, and a reversing pin 20 is installed on the other side. One end of the torsion spring 16 abuts against the side of the pawl 23, and the other end of the torsion spring 16 abuts against the side of the reversing pin 20. When the handle body 1 rotates, the torque is transmitted to the torsion spring 16 through the claw 18. The torsion spring 16 deforms and generates a reset stress. Once the external force is removed from the handle body 1, the torsion spring 16 drives the handle body 1 to quickly reset under the action of the reset stress through the claw 18 without jamming. It should be noted that the reversing pin 20 is used to reverse the installation of the handle body 1 on the door panel. Specifically, two observation holes 24 are arranged on the middle frame 2. The position of the reversing pin 20 can be observed through the observation holes 24. When the reversing pin 20 is located on the right side of the middle frame 2, the handle assembly is adapted to open the door on the right side when installed on the door panel. When the reversing pin 20 is located on the left side of the middle frame 2, the handle assembly is adapted to open the door on the left side when installed on the door panel. Regardless of whether the handle assembly is in the right-hand or left-hand opening position, the reversing pin 20 and the claw 23 maintain abutting contact with the two ends of the torsion spring 16 respectively.

[0049] Furthermore, such as Figure 7 , 8 As shown in Figure 11, in this embodiment, the rotating shaft 9 has a columnar structure, and the front end of the rotating shaft 9 is formed as a transmission seat 25. The transmission seat 25 can be connected to the lock tongue. The transmission seat 25 has symmetrical second slots 26, and the claw 18 has symmetrical protrusions 27. The protrusions 27 engage with the second slots 26, so that the claw 18 is engaged with the rotating shaft 9. Specifically, in order to enable the handle assembly to output torque to the lock tongue or lock tongue mechanism of the smart door lock, the front end of the rotating shaft 9 is formed as a transmission seat 25. The transmission seat 25 is a rectangular slot, and the torque of the handle body 1 is transmitted to the lock tongue through the transmission seat 25. To achieve automatic reset of the handle body 1, two symmetrical second slots 26 are provided at the front end of the rotating shaft 9, with the second slots 26 located on the end face of the transmission seat 25. Corresponding to the second slots 26, the claw member 18 has two symmetrical protrusions 27 facing the center of the claw member 18. When the claw member 18 is installed, the protrusions 27 engage with the second slots 26. After the claw member 18 is pressed by the retaining spring 19, the torque of the rotating shaft 9 can be transmitted to the claw member 18 through the protrusions 27, and then to the torsion spring 16 through the claw member 18, causing the torsion spring 16 to generate reset stress. After the handle body 1 is released, the reset stress of the torsion spring 16 can be reversed and transmitted to the handle body 1, thereby achieving automatic reset of the handle body 1.

[0050] Furthermore, such as Figure 5As shown, in this embodiment, limit posts 28 are symmetrically arranged on the base 15, and the two ends of the torsion spring 16 abut against the limit posts 28 respectively; a limit block 29 is provided on the base 15, and the end of the torsion spring 16 stops at the limit block 29. Specifically, in order to stably install the torsion spring 16 on the base 15, two limit posts 28 are symmetrically protruded from the inner bottom surface of the base 15. When the torsion spring 16 is fitted onto the outer side of the bushing 17, the two ends of the torsion spring 16 abut against the side of the limit post 28 respectively, to prevent the torsion spring 16 from losing its obstruction during reset and causing the handle body 1 to fail to reset. Furthermore, in order to limit the rotation angle of the handle body 1 when opening the door, a limit block 29 is also provided inwardly on the bottom surface of the base 15. The limit block 29 is located on the vertical line of the two limit posts 28 and extends in an arc shape to both sides to accommodate the rotation of the torsion spring 16. It should be noted that the extension angle of the limit block 29 can be designed according to the required rotation angle of the handle body 1. The rotation angle of the handle body 1 also needs to be set according to the travel of the latch. Usually, the rotation angle of the handle body 1 is about 55 degrees up and down, that is, the handle body 1 can rotate 55 degrees in the forward direction and 55 degrees in the reverse direction.

[0051] Furthermore, such as Figure 3 , 5 As shown in Figure 11, in this embodiment, the base 15 is provided with a plurality of symmetrical mounting ears 30, and the middle frame 2 is provided with a plurality of mounting holes 31. Screws pass through the mounting holes 31 to fasten the mounting ears 30. Specifically, in order to achieve a fast installation connection between the base 15 and the middle frame 2, two pairs of mounting ears 30 are symmetrically provided on the outer side of the base 15. The mounting ears 30 extend outward from the base 15, and threaded holes can be formed on the mounting ears 30. Four mounting holes 31 are provided on the bottom surface of the middle frame 2 corresponding to the mounting ears 30. Screws pass through the mounting holes 31 and are fastened to the threaded holes of the mounting ears 30, thereby making the base 15 and the middle frame 2 fastened. The base 15 can be adapted to the retaining spring 19 to clamp the claw 18 and the bushing 17, resulting in a more stable structure and a longer service life.

[0052] Furthermore, such as Figure 3 , 10As shown in Figure 12, in this embodiment, a reinforcing pad 32 is provided at the front end of the handle body 1. The reinforcing pad 32 is fitted onto the rotating shaft 9 and abuts against the rear end of the base 15. The reinforcing pad 32 has an outwardly turned edge 33, with the back side of the outwardly turned edge 33 facing the fingerprint connection line 4. Specifically, in order to make the structure of the handle assembly more compact and stable, a reinforcing pad 32 is provided at the front end of the handle body 1. The reinforcing pad 32 is fitted onto the rotating shaft 9 and located behind the mounting base 21. The reinforcing pad 32 abuts against the rear end of the base 15. Preferably, the reinforcing pad 32 can be glued to the rear end of the base 15 with double-sided adhesive 34. When the handle body 1 impacts towards the door panel, the front end of the handle body 1 can press against the back of the reinforcing pad 32, or the stepped seat 14 of the handle body 1 can abut against the handle cover plate, thereby limiting the impact of the handle body 1 on the base 15 and preventing damage to the handle rotation assembly 8. The reinforcing shim 32 enhances the impact resistance of the handle rotation assembly 8, improves the safety performance of the handle assembly, and extends its service life. In particular, the handle rotation assembly 8 is less likely to be damaged in the event of violent attack, resulting in a better safety factor. Preferably, the edge of the shim is formed as an outwardly flanged edge 33 with a rounded transition. The back side of the outwardly flanged edge 33 faces the space accommodating the fingerprint connection line 4. The rounded outwardly flanged edge 33 can prevent the fingerprint connection from being hinged or cut during operation.

[0053] Furthermore, such as Figure 4 , 5 As shown in Figure 12, in this embodiment, the base 15 is provided with a plurality of symmetrical positioning holes 35, and the handle cover is provided with a plurality of symmetrical positioning posts 36. The positioning holes 35 are fitted into the positioning posts 36 for installation. Specifically, in order to facilitate the positioning and installation of the base 15, the base 15 is symmetrically provided with four positioning holes 35, and the handle cover is symmetrically provided with four positioning posts 36. The positioning holes 35 are provided corresponding to the positioning posts 36. When installing the handle rotating assembly 8, the positioning holes 35 are fitted into the positioning posts 36 for installation. More specifically, when assembling the handle assembly of this embodiment, the handle rotating assembly 8 is first assembled, and then the handle rotating assembly 8 and the middle frame 2 are fastened and assembled with screws; then the reinforcing shim 32 is fitted onto the rotating shaft 9 for installation, and then the handle body 1 with the fingerprint connecting line 4 threaded through it is fitted onto the handle cover. The fingerprint connecting line 4 passes through the clearance groove 5 and the guide groove 7 and is led out from the opening groove 12; finally, the rotating shaft 9 is inserted into the connecting groove 6 and fastened with the fastener 10, thereby completing the assembly.

[0054] Furthermore, such as Figure 3 , 11As shown in Figure 12, in this embodiment, the handle body 1 includes an upper cover 37 and a lower shell 38, which together form a receiving cavity 13. The fingerprint module 3 is installed in the receiving cavity 13, and the fingerprint sensor 39 of the fingerprint module 3 is exposed outside the upper cover 37. A wire clip 40 is provided on the back of the fingerprint module 3, which holds the fingerprint connection cable 4. Specifically, in order to securely install the fingerprint module 3 inside the handle body 1, the handle body 1 includes an upper cover 37 and a lower shell 38, which together form a receiving cavity 13. The receiving cavity 13 is used to install the fingerprint module 3, and the fingerprint module 3 can be fastened inside the receiving cavity 13 with screws. More specifically, the fingerprint module 3 includes a sensor 39, which is used to collect fingerprint information and transmit it to the controller via the fingerprint chip 41 of the fingerprint module 3 and the fingerprint connection cable 4. The sensor 39 is exposed outside the upper cover 37 to facilitate fingerprint pressing by the user. A wire clip 40 is provided on the back of the fingerprint module 3. The wire clip 40 is used to hold the fingerprint connection cable 4 so that the fingerprint connection cable 4 is always kept stable in the receiving cavity 13.

[0055] Furthermore, such as Figure 2 , 3 As shown in Figure 11, in this embodiment, a through hole 42 is provided on one side of the middle frame 2. The rotating shaft 9 is coaxially installed with the through hole 42, and the transmission seat 25 faces the through hole 42. Specifically, in order to facilitate the installation of the rotating component and realize torque output, a through hole 42 is provided on the front side of the middle frame 2. The through hole 42 is a round hole with a diameter slightly larger than the circumference of the transmission seat 25. The rotating shaft 9 is coaxially installed with the through hole 42, and the transmission seat 25 faces the through hole 42. The fastener 10 can pass through the through hole 42 and through the transmission seat 25 to reach the bottom end of the rotating shaft 9 and connect to the handle body 1, so that the rotating component and the handle body 1 are connected and installed.

[0056] Furthermore, embodiments of this utility model also provide a smart door lock using the aforementioned handle assembly. The handle assembly can be adapted to the front panel of the smart door lock for installation. The controller is located on the front or rear panel, and the fingerprint connection cable 4 is connected to the controller. By arranging the fingerprint connection cable 4 between the inner bottom of the handle cover 11 and the bottom of the handle rotating assembly 8, the fingerprint connection cable 4 only moves at the bottom of the handle rotating assembly 8 when the handle body 1 is rotated. This avoids problems such as wire twisting, scratching, and breakage, prevents the smart door lock from failing due to fingerprint module 3 malfunction, and results in a more compact door lock structure and a longer service life.
