Description

Technical Field

[0001] This invention belongs to the field of lock accessories, specifically relating to a multifunctional door handle, a smart panel, and a smart door lock. Background Technology

[0002] Smart locks are locks that differ from traditional mechanical locks in that they are more intelligent and convenient in terms of user security, identification, and management. They are the locking components in access control systems and are composite locks with security, remote control, quick password modification, user identification information, and advanced technology. They are widely used in residences, hotels, and other similar establishments.

[0003] Among them, smart door locks need to be equipped with motors to realize the electric rotation control of the square steel, thereby controlling the extension and retraction of the bolt on the lock body to realize the electric control of unlocking and / or locking.

[0004] The existing motors include the following two configurations:

[0005] The first type, such as the "Door Lock Device and Anti-theft Door" disclosed in Chinese Patent No. CN202221434600.5, involves placing the motor inside the panel and using a gear set or other transmission structure to link the motor and the rotating rod. A control signal (password, fingerprint, remote control, etc.) is given to the motor to electrically rotate the rod, thus unlocking and / or locking. The drawback of this first method is that it requires the motor, gear set, and other structures to be mounted on the panel. This necessitates providing space for the installation of these structures, resulting in a large overall panel size and thickness. Consequently, the smart door lock mounted on the door appears bulky and aesthetically unappealing, and the panel layout is quite complex.

[0006] The second method, as disclosed in Chinese Patent No. CN202422829616.1, "A Drive Mechanism for a Fully Automatic Intelligent Lock," involves placing the motor inside the lock housing and using a gear set or other transmission structure to link the motor and the square shaft assembly. This allows a control signal (password, fingerprint, remote control, etc.) to the motor to electrically rotate the square shaft sleeve, thus unlocking and / or locking. The drawbacks of this second method are: due to the complex internal structure of the lock body, further integrating the motor, gear set, and other structures within the lock body would complicate the manufacturing process and increase production costs. Additionally, since the lock body is built into the door, maintenance requires removing the lock body from the door, leading to inconvenience. Summary of the Invention

[0027] To enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection of the present invention, the present invention will be described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present invention, and are merely a part of the embodiments of the present invention. The specific and direct descriptions of related structures are only for the convenience of understanding the present invention, and the specific features do not necessarily or directly limit the scope of the present invention. Conventional choices and substitutions made by those skilled in the art under the guidance of the present invention should be considered within the scope of protection of the present invention.

[0028] Example 1: like Figures 1-11 As shown, the present invention discloses a multifunctional door handle, comprising: The first fixing body 13 needs to be installed on a carrier such as a door to realize the installation of the door handle; The rotating body 1 and the first fixed body 13 are installed in a relative rotational manner with k1 as the axis of rotation. The rotating body 1 is provided with a power mounting position 11 and an external drive part 12. Output component 2 and the first fixed body 13 are installed in a relative rotational configuration about k1 as the axis of rotation; The power unit 3 is installed at the power mounting position 11. The power unit 3 is used to drive the output component 2 to rotate. The power unit 3 includes a power motor 31, which serves as the power source for the power unit 3. The user contacts the external drive unit 12 and applies force to the external drive unit 12 to make the rotating body 1 rotate relative to the first fixed body 13, thereby driving the output unit 2 to rotate.

[0029] When in use, the door handle is installed on the door, and the door is unlocked and / or locked by rotating the output component 2.

[0030] Therefore, 1. When the door needs to be opened manually, the user holds the outer drive unit 12 and applies force to drive the rotating body 1 to rotate relative to the first fixed body 13, thereby driving the output component 2 to rotate, so that the rotating output component 2 outputs to unlock and / or lock the door. 2. When the door needs to be opened electrically (such as remote control, password, fingerprint, face recognition), a control signal is given to the power motor 31 to start working, the power motor 31 works and drives the output component 2 to rotate, so that the rotating output component 2 outputs to unlock and / or lock the door. 3. Since the power device 3 used to control the rotation of the output component 2 is set on the rotating body 1, compared with the first case in the background technology, there is no need to design and install space on the panel, so as to reduce the volume and thickness of the panel. This not only makes the panel more beautiful, but also makes the panel layout easier. Compared with the second case in the background technology, there is no need to design and install space inside the lock body 9, simplifying the structure of the lock body 9, simplifying the production process, reducing production costs, and making maintenance more convenient.

[0031] In addition, this embodiment also includes a clutch assembly 4, which includes a first component 41, a second component 42, a clutch component 43 and a switching structure 44. The first component 41 is linked to the rotating body 1, the second component 42 is linked to the power device 3, and the clutch component 43 is linked to the output component 2.

[0032] The clutch component 43 is driven by the switching structure 44 to form a manual state that engages with the first component 41 and an electric state that engages with the second component 42; Figure 8 As shown, in manual mode, the external drive unit 12 is driven to rotate the rotating body 1 so as to drive the output unit 2 to rotate under the cooperation of the first component 41 and the clutch component 43. Figure 5 As shown, in electric mode, the power motor 31 operates to drive the output component 2 to rotate in cooperation with the second component 42 and the clutch component 43.

[0033] Specifically, the first component 41 has an internal toothed hole 412 through it along the direction of k1, and the peripheral wall of the internal toothed hole 412 has a first internal tooth part 411. The first component 41 is fixedly mounted on the rotating body 1, and the output component 2 passes through the internal toothed hole 412. The second component 42 is provided with a second external tooth 421 on its outer periphery, and the second component 42 is fixedly mounted on the output end of the power device 3. The clutch component 43 is provided with a clutch external tooth 431 on its outer periphery. The clutch component 43 is slidably mounted on the output component 2 along the direction of k1, and the clutch component 43 and the output component 2 are arranged to rotate synchronously in the circumferential direction. The first internal tooth portion 411 and the first external tooth portion are staggered in the direction of k1; In manual mode, the clutch external gear 431 and the first internal gear 411 cooperate to form a gear coupling, and the clutch external gear 431 and the second external gear 421 are separated. In the electric state, the clutch external tooth 431 and the second external tooth 421 are engaged, and the clutch external tooth 431 and the first internal tooth 411 are separated.

[0034] Therefore, 1. When the door needs to be opened manually, the user operates the switching structure 44 to cause the clutch component 43 to move in the direction of k1 and engage with the first component 41. Specifically, the clutch component 43 enters the internal toothed hole 412, and a gear coupling is formed by the engagement of the external clutch toothed part 431 and the first internal toothed part 411. This causes the rotating body 1, the first component 41, the clutch component 43, and the output component 2 to rotate synchronously in the circumferential direction. Since the clutch component 43 and the second component 42 are separated, the linkage between the power unit 3 and the output component 2 is cut off. Then, the rotating body 1 is rotated by the external drive part 12. The rotation of the output component 2 can be achieved through the cooperation of the first component 41 and the clutch component 43. 2. When the door needs to be opened electrically, the user controls the switching structure 44 to make the clutch component 43 move in the direction of k1 to cooperate with the second component 42. Specifically, the clutch external tooth 431 and the second external tooth 421 mesh. Since the clutch component 43 and the first component 41 are set separately to cut off the linkage between the rotating body 1 and the output component 2, after giving the power motor 31 a start-up control signal, the power motor 31 can work to achieve the rotation of the output component 2 through the cooperation of the second component 42 and the clutch component 43.

[0035] Specifically, the rotating body 1 extends along the direction of k1 in the length direction, the first fixed body 13 is located at one end of the length of the rotating body 1, and the external drive part 12 is located at the other end of the length of the rotating body 1; in addition, the switching structure 44 includes a switching press part 441 located on the outside of the rotating body 1 and / or the external drive part 12, and the user can switch to manual mode by pressing down the switching press part 441.

[0036] Specifically, the output component 2 includes, in sequence along the direction of k1, an extension section 21, a first mounting section 22, an internal section 23, and a second mounting section 24. The second mounting section 24 is cylindrical, and correspondingly, a cylindrical groove is provided inside the rotating body 1. The second mounting section 24 is directly inserted into the cylindrical groove, or is mounted in the cylindrical groove by means of a bearing, so that the second mounting section 24 can be rotatably mounted on the rotating body 1. The internal section 23 is located inside the rotating body 1. The first mounting section 22 is rotatably mounted on the first fixed body 13. The extension section 21 extends out of the first fixed body 13 in a direction away from the rotating body 1.

[0037] Therefore, the stability of the output component 2 is improved by rotating the second mounting section 24 to the rotating body 1 and rotating the first mounting section 22 to the first fixed body 13.

[0038] Specifically, the length of the inner section 23 near the end of the first mounting section 22, the first mounting section 22 and the outer section 21 are square column-shaped. The outer periphery of the first mounting section 22 is fitted with a connector 5 with a square hole on the inner periphery and a cylindrical shape on the outer periphery, so that the first mounting section 22 can be rotated relative to the first fixed body 13 through the cooperation of the connector 5 and the first fixed body 13. In addition, a torsion spring 51 is provided between the connector 5 and the first fixed body 13, so that after the power device 3 and / or the rotating body 1 drives the output part 2 to rotate to unlock, the torsion spring 51 drives the output part 2 to rotate to reset and lock.

[0039] The rest of the internal segment 23 is cylindrical.

[0040] Preferably, the length of the outer drive portion 12 extends along the direction of k2, and one end of the length of the outer drive portion 12 is connected to the rotating body 1; wherein, the directions of k1 and k2 are perpendicular to each other, so that the combination of the rotating body 1 and the outer drive portion 12 forms an L-shape, which is the shape of a common door handle; wherein, the switching press portion 441 is provided on the outer periphery of the outer drive portion 12, and the user presses down the switching press portion 441 by holding the outer periphery of the outer drive portion 12 to switch to manual mode.

[0041] Therefore, if manual opening is required, the user should use the same method as with traditional L-shaped door handles to make opening the door more convenient.

[0042] Specifically, the switching structure 44 also includes a sliding member 442 and a flipping member 443. The sliding member 442 is slidably mounted on the rotating body 1, and the flipping member 443 is rotatably mounted on the outer drive unit 12 about k3 as the axis of rotation. The sliding member 442 is located on the rotation trajectory of the flipping member 443, and the clutch component 43 is located on the sliding trajectory of the sliding member 442. The directions of k1, k2, and k3 are arranged perpendicularly to each other. The flipping member 443 is located on the movement trajectory of the switching press part 441. The user presses the switching press part 441 to drive the flipping member 443 to rotate. The rotating flipping member 443 drives the sliding member 442 to slide. The sliding member 442 drives the clutch component 43 to separate from the second component 42 and cooperate with the first component 41 to switch to manual mode.

[0043] Preferably, the rotating body 1 has a first inner cavity 61, and the power unit 3, the first component 41, the second component 42, the clutch component 43, and the sliding component 442 are all disposed in the first inner cavity 61. The outer drive part 12 has a second inner cavity 62, and the flipping component 443 is disposed in the second inner cavity 62. This makes the door handle have a simpler appearance.

[0044] Preferably, the switching pressing part 441 is disposed on the side of the outer drive part 12 facing the first fixed body 13 in the direction of k1, so that after the door handle is installed on the door, the flipping part 443 faces the side of the door, making the appearance more concise. The switching pressing part 441, which moves in the direction of k1, can drive the end of the flipping part 443 near the switching pressing part 441 to flip in the direction of k1, so as to drive the end of the flipping part 443 near the sliding part 442 to flip in the direction of k1, thereby driving the sliding part 442 to slide in the direction of k1 more smoothly.

[0045] Preferably, the switching press 441 is an elongated strip extending along the direction of k2, and the switching press 441 is slidably mounted on the outer drive unit 12 along the direction of k1. Therefore, when the user holds the outer drive unit 12, the elongated switching press 441 can be pressed down by multiple fingers to make the movement more stable.

[0046] In other embodiments, the switching press part 441 may also be provided at the bottom of the outer drive part 12, so that it also has a hidden effect. However, it is necessary to make an adaptive structural replacement, such as using a slope, so that the upward movement of the switching press part 441 can also drive the rotation of the flipping member 443.

[0047] Specifically, the sliding component 442 includes an input link 4421, an output link 4422, and two guide links 4423. The length direction of the two guide links 4423 is along the direction of k1. Two guide holes are provided through the rotating body 1 along the direction of k1. The guide links 4423 and the guide hole sleeves cooperate to realize the guide sliding installation of the two guide links 4423 on the rotating body 1. The two ends of the input link 4421 are connected to one end of the different guide links 4423 by bolts or other means. The two ends of the output link 4422 are connected to the other end of the different guide links 4423 by bolts or other means. In addition, the output link 4422 is provided with a push ring 44221 sleeved on the outer periphery of the output component 2. The input link 4421 is used to drive the sliding component 442 to slide under the action of the flipping component 443, and the push ring 44221 is used to push the clutch component 43 to move as the sliding component 442 slides.

[0048] Therefore, the rotating member 443 rotates and pushes the middle part of the input link 4421, so that the input link 4421 is subjected to a thrust in the direction of k1, and the output link 4422 slides under the cooperation of the guide link 4423 and the guide hole, so that the push ring 44221 can push the clutch component 43 to push the clutch component 43 away from the second component 42 and closer to the first component 41, thus switching from electric state to manual state.

[0049] The inner circumference of the push ring 44221 and the outer circumference of the cylindrical section of the built-in section 23 are matched, which in turn improves the smoothness of the guide sliding.

[0050] Furthermore, the clutch assembly 4 in this embodiment includes a first reset member 71, which is used to drive the clutch component 43 to move and reset from the manual state to the electric state. That is, in the non-contact door handle state, the linkage between the power unit 3 and the output component 2 can be guaranteed at all times so as to unlock the door electrically at any time.

[0051] Specifically, the first reset member 71 is a compression spring, which is sleeved on the output member 2. One end of the compression spring abuts against the clutch member 43, and the other end abuts against the connecting member 5. This allows the first reset member 71 to elastically reset after the pressure on the switching press part 441 is released, thereby driving the clutch member 43 away from the connecting member 5 and the first member 41, and engaging the clutch member 43 and the second member 42.

[0052] In addition, in this embodiment, a second reset spring 72 is sleeved around the guide rod 4423. One end of the second reset spring 72 abuts against the output rod 4422, and the other end abuts against the first component 41. The end portion of the guide rod 4423 is inserted into the first component 41. This allows the second reset component to elastically reset after the pressure on the switching press part 441 is released, driving the output rod 4422 away from the first component 41, coordinating with the movement of the clutch component 43.

[0053] It should be noted that the edges of the first internal tooth portion 411, the second external tooth portion 421, and the clutch external tooth portion 431 all need to be chamfered to make the docking smoother.

[0054] Preferably, the power unit 3 in this embodiment further includes a planetary reducer 32. The input end of the planetary reducer 32 is located at one end of the planetary reducer 32 along the k1 direction, and the input end of the planetary reducer 32 is connected to the output end of the power motor 31. The output end of the planetary reducer 32 is located at the other end of the planetary reducer 32 along the k1 direction, and the output end of the planetary reducer 32 is connected to the second component 42.

[0055] Therefore, the layout of the power motor 31, planetary reducer 32 and the second component 42 along the k1 direction, and the planetary reducer 32 itself having the characteristics of being long in the axial direction and small in the circumference, make the length direction of the rotating body 1 along this direction, thereby making more compact use of the space of the first inner cavity 61 and making the rotating body 1 slimmer and more beautiful.

[0056] Example 2: like Figure 12As shown, the present invention also discloses a multifunctional door handle, the main structure of which is the same as that of Embodiment 1, except that the switching pressing part 441 is integrally formed on the flipping part 443. The switching pressing part 441 extends out of the outer drive part 12 through the opening on the second inner cavity 62. When the user holds the outer drive part 12, the switching pressing part 441 is pressed and flipped with the flipping part 443 and enters the second inner cavity 62.

[0057] This setup results in fewer parts.

[0058] Example 3: like Figure 13 As shown, the present invention also discloses a multifunctional door handle, the main structure of which is the same as that of Embodiment 1. The difference is that the outer drive part 12 is arranged in a ring around the outer periphery of the rotating body 1, and correspondingly, the flipping part 443 is not provided, and the switching pressing part 441 is provided on the input link 4421 and protrudes from the side of the rotating body 1 away from the first fixed body 13.

[0059] Therefore, the user holds the external drive unit 12 with one hand and can press down the switching press unit 441 with the same hand or the other hand, so that the switching press unit 441 is pressed and directly drives the sliding member 442 to slide.

[0060] This design allows for even fewer parts and a shape that fits a conventional cylindrical door handle.

[0061] Example 4: like Figure 14 As shown, the present invention discloses a smart panel 8, comprising: The panel body 81 is provided with a fingerprint recognition area and / or a password area and / or a face recognition area; In any of the embodiments one to three, the first fixing body 13 is fixed to the panel body 81.

[0062] This eliminates the need for a power unit 3 within the panel body 81, thus simplifying the panel body 81.

[0063] It should be noted that the smart panel 8 is usually installed on the side of the door facing outwards, while the door handle, having a manual mode that can directly drive the output component 2 to rotate, typically needs to be installed on the side of the door facing inwards. Therefore, this solution is only suitable for a few specific environments.

[0064] Example 5: like Figures 15-17 As shown, this invention discloses a smart door lock, comprising: Lock body 9, which is provided with square shaft hole 91, lock cylinder hole 92, oblique tongue 93 and square tongue 94, with oblique tongue 93 corresponding to square shaft hole 91 and square tongue 94 corresponding to lock cylinder hole 92; In any of the embodiments one to three, the output component 2 is inserted into the square shaft hole 91 so that the square shaft hole 91 and the output component 2 are arranged to rotate synchronously. The lock cylinder 10 is partially disposed in the lock cylinder hole 92. The lock cylinder 10 is provided with a second fixing body 101. The first fixing body 13 and the second fixing body 101 are located on the same side of the lock body 9 and are used for fixing the lock cylinder 10 for installation with the door. The second fixing body 101 is also provided with a knob 102. The smart panel 8 and the first fixed body 13 are located on both sides of the lock body 9. The output part 2 also extends out of the square shaft hole 91 and is connected to the smart panel 8. The lock cylinder 10 also extends out of the lock cylinder hole 92 and partially extends through the smart panel 8.

[0065] Therefore, on the side of the door facing inward, the latch 93 can be opened by operating the external drive unit 12, and the square latch 94 can be opened and closed by the knob 102. On the side of the door facing outward, the latch 93 can be opened by driving the motor 31 through the fingerprint recognition area and / or password area and / or face recognition area.

[0066] In this embodiment, the first fixing body 13 and the second fixing body 101 are separately arranged so that the first fixing body 13 and the second fixing body 101 can be installed on the door respectively, thereby adapting to different door and lock body 9 models.

[0067] In other embodiments, the first fixing body 13 and the second fixing body 101 may also be integrally formed to make the overall structure simpler.

[0068] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
