Description

Technical Field

[0001] The present invention relates to the field of door locks. Background Art

[0002] Door lock products such as automatic door locks and intelligent door locks can achieve automatic locking and unlocking, which greatly facilitates users. The mechanical lock body technology is mature and the cost is low. Therefore, at present, many automatic door locks adopt the structure of driving the mechanical lock body by a motor. The locking and unlocking structure on the mechanical door lock includes a square rod and a lock core. The square rod is usually used to connect with the door handle of the door lock for the handle to rotate and unlock, and the lock core is used for key locking and unlocking. In these existing automatic door locks, the motor usually controls the lock body by connecting with the lock core. In this way, the lock body needs to adopt a specially customized lock core. The front section of this kind of lock core is a lock cylinder for key opening, and the rear section needs to be provided with flat strips, etc. for the motor to connect and drive, which will increase the product cost. In addition, controlling the lock body through the lock core by the motor requires a large driving force and generally needs to rotate two circles to open and close the door, with high power consumption, which will reduce the battery life of the door lock. Both the product cost and the usage cost will increase, and the time required to open the door will also be longer, affecting the user experience. Summary of the Invention

[0003] An object of the present invention is to at least solve one of the technical problems existing in the prior art, and provide a door lock structure that helps to reduce costs and shorten the unlocking time.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The function of the accompanying drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention. However, it should not be construed as a limitation on the protection scope of the present invention.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as "arrangement", "installation", and "connection" should be understood in a broad sense. Those skilled in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0031] Referring to Figures 1 to 4 , in the first preferred embodiment of the present invention, a door lock structure is provided, including: a panel 10, on which a handle 20 is rotatably arranged; a free member 30, rotatably arranged on the panel 10, and a clutch device is arranged between the free member 30 and the handle 20, and the clutch device can be operated to switch the engagement and separation between the free member 30 and the handle 20; a lock rod 50, connected to the free member 30 and rotatable with the free member 30, and the lock rod 50 is used to connect to a lock body 80; a driving motor 61, arranged on the panel 10, for driving the free member 30 to rotate. In this door lock structure, the driving motor 61 can drive the free member 30 to rotate, and the free member 30 is connected to the lock rod 50, so that during use, the driving motor 61 can directly perform the locking and unlocking operations of the lock body 80 through the lock rod 50. At the same time, through the clutch device, it can be realized that when the driving motor 61 drives the free member 30 to rotate, it will not drive the handle 20 to rotate. Therefore, compared with the traditional structure of driving the lock core by a motor, the requirement for the driving force of the driving motor 61 is effectively reduced, the angle size that the driving motor 61 needs to control the rotation of the free member 30 is reduced, the product cost can be effectively reduced, the battery life can be extended, the user's usage cost is reduced, and at the same time, the unlocking time can be effectively shortened, improving the user experience.

[0032] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0033] Referring to Figure 3 and Figure 4 , in this embodiment, a connection hole 31 adapted to the lock rod 50 is provided on the free member 30, and the lock rod 50 is inserted into the connection hole 31 to be connected to the free member 30, which is convenient for processing and disassembly and helps to reduce the product cost. In other embodiments, the free member 30 can also be connected to the lock rod 50 by other common connection methods such as screws, bonding, and riveting. In this embodiment, the lock rod 50 is a square rod adapted to most existing lock bodies 80, and the connection hole 31 is correspondingly a square hole. In other embodiments, the shape and structure of the lock rod 50 can also be flexibly adjusted according to the type of the lock body 80, etc.

[0034] Referring to Figure 1 ,Figure 3 and Figure 4 , in this embodiment, an operable control part 21 is arranged on the handle 20, and the clutch device is controlled by the control part 21. In this way, it is convenient to control the clutch device through the control part 21 while holding the handle 20, which is convenient for the user to operate the lock with one hand and is easy to use. In other embodiments, the control part 21 of the clutch device can also be arranged on the panel 10 or other suitable positions, or the operation of the clutch device can also be controlled by other control methods such as fingerprint recognition, voice recognition, and wireless control.

[0035] In this embodiment, the clutch device includes a clutch lever 41 movably arranged on the handle 20 and a clutch hole 42 correspondingly arranged on the free part 30; an operating part 22 is rotatably arranged on the handle 20, and the control part 21 is located at one end of the operating part 22 and can be operated to rotate the operating part 22. The other end of the operating part 22 abuts against the clutch lever 41. During use, when the user holds the handle 20, the control part 21 can be pressed simultaneously, so that the operating part 22 rotates, and then the clutch lever 41 is pushed into the clutch hole 42 through the operating part 22, so that the handle 20 is engaged with the free part 30, and the rotation of the handle 20 can drive the lock lever 50 to operate the lock body 80. The structure is simple and reliable, and is convenient for processing, assembly, operation and use. In other embodiments, other common clutch structures can also be adopted for the clutch device. For example, a magnetic clutch structure can be adopted, etc., and other common control structures such as a knob and a rotary knob can also be adopted for the control part 21, which is not limited thereto.

[0036] In this embodiment, the control part 21 is located on the side of the handle 20 facing the panel 10. In this way, the control part 21 will not be exposed during use, which can keep the outer side of the handle 20 regular and beautiful, prevent misoperation, and avoid the control part 21 from being collided and causing faults or damage, and is also convenient for operation. In other embodiments, the control part 21 can also be selectively arranged on the side of the handle 20 facing away from the panel 10 or other arbitrary suitable positions, which is not limited thereto.

[0037] In this embodiment, an elastic reset member 43 is provided between the clutch lever 41 and the handle 20. The elastic reset member 43 is used to drive the clutch lever 41 to move out of the clutch hole 42. In this way, after the user releases the handle 20, the clutch lever 41 and the operating member 22 can be automatically reset to separate the handle 20 from the free member 30, avoiding affecting the operation of the driving motor 61 in the future. Moreover, since the elastic reset member 43 is arranged between the clutch lever 41 and the handle 20, it helps to simplify the structure and is convenient for processing and assembly. In other embodiments, the elastic reset member 43 can also be optionally arranged between the operating member 22 and the handle 20, and at the same time, the clutch lever 41 is connected to the operating member 22, so that the reset of the operating member 22 can drive the clutch lever 41 to move and reset; or the elastic reset member 43 can also be optionally arranged between the clutch lever 41 and the panel 10, etc. In this embodiment, the elastic reset member 43 uses a spring sleeved outside the clutch lever 41, which has a simple structure and is convenient for processing, manufacturing and assembly. In other embodiments, the elastic reset member 43 can also be optionally other common elastic structures such as elastic sheets, not limited to this; or other operable reset structures can also be provided to drive the clutch lever 41 to reset manually by the user or automatically through a motor, etc. Those skilled in the art can make flexible choices and are not limited to this.

[0038] Referring to Figures 2 to 4 , in this embodiment, the free member 30 has a first initial state and an operating state after rotating relative to the first initial state. A driving member 62 is movably arranged on the panel 10. The driving member 62 has a second initial state. The driving motor 61 is used to drive the driving member 62 to move so as to drive the free member 30 to rotate; a clearance structure is provided between the driving member 62 and the free member 30. The clearance structure is used to prevent the free member 30 from driving the driving member 62 to move when the driving member 62 is in the second initial state during the rotation from the first initial state to the operating state. In this way, during use, when the clutch device engages the free member 30 with the handle 20 and the user rotates the handle 20 to lock or unlock, the clearance structure can prevent the handle 20 from driving the driving member 62 to move through the free member 30, that is, it will not drive the output shaft of the driving motor 61 to rotate, which can effectively protect the driving motor 61, reduce the failure rate, and can also prevent the driving motor 61 from increasing the resistance of the handle 20 to rotate, facilitating operation; when the driving motor 61 is required to perform automatic locking and unlocking, the driving motor 61 can first make the driving member 62 compensate for the movement of the clearance structure, and then make the driving member 62 continue to move to drive the free member 30 to rotate, so as to complete the locking and unlocking operation.

[0039] In this embodiment, the driving member 62 is rotatably arranged on the panel 10; the clearance structure includes a first abutting portion 32 arranged on the free member 30 and a second abutting portion 63 arranged on the driving member 62. When the free member 30 is in the first initial state and the driving member 62 is in the second initial state, the first abutting portion 32 and the second abutting portion 63 are spaced apart by a distance; the driving motor 61 can drive the driving member 62 to rotate so that the second abutting portion 63 abuts against the first abutting portion 32, and then the driving member 62 can drive the free member 30 to rotate. During use, when the handle 20 is rotated to lock or unlock the door, the first abutting portion 32 of the free member 30 rotates within the range of the interval between it and the second abutting portion 63, so that the driving member 62 will not be driven to rotate. When the driving motor 61 is used to automatically lock or unlock the door, the driving member 62 can first rotate to make the first abutting portion 32 and the second abutting portion 63 abut, and then continue to rotate to drive the free member 30 to rotate, thereby realizing locking and unlocking.

[0040] In this embodiment, the number of the second abutting portions 63 is two and they are respectively arranged on the opposite sides of the first abutting portion 32. In this way, neither the forward rotation nor the reverse rotation of the handle 20 will drive the driving member 62 to rotate. The handle 20 can switch operations such as locking and anti-locking by switching the rotation direction. Similarly, the driving motor 61 can also drive the free member 30 during both forward and reverse rotations, which is beneficial to increasing the functions of the door lock. In other embodiments, the number of the first abutting portions 32 can also be two and they are respectively arranged on the opposite sides of the second abutting portion 63, and the same effect can be obtained. In this embodiment, the driving member 62 is in a disk shape, and an arc-shaped receiving hole 65 is formed thereon. The two second abutting portions 63 are respectively the two ends of the receiving hole 65, and the first abutting portion 32 of the free member 30 is in a convex block shape and is inserted into the receiving hole 65, which is convenient for processing and manufacturing, and can also prevent the first abutting portion 32 and the second abutting portion 63 from being misaligned and causing failures, and is more reliable. In other embodiments, the first abutting portion 32 and the second abutting portion 63 can also adopt any other suitable abutting structures and are not limited thereto.

[0041] In this embodiment, it is set that there are two operating states of the free member 30, which are obtained by rotating the free member 30 in two directions respectively. The rotation angle of the free member 30 from the first initial state to any one of the operating states is 40°, that is, the handle 20 can rotate 40° in any one direction to complete the corresponding operation on the lock body 80; when the driving motor 61 is used for automatic operation, the corresponding driving member 62 needs to first rotate 40° to compensate for the clearance structure, and then continue to rotate 40° to complete the operation on the lock body 80. Compared with the traditional automatic door lock that requires the lock core to rotate two circles for locking and unlocking, the operation time is still effectively shortened. In other embodiments, the rotation angle of the free member 30 from the initial state to the operating state can also be flexibly adjusted according to needs.

[0042] In this embodiment, the driving motor 61 drives the driving member 62 to rotate through the gear transmission mechanism 66, and the gear connected to the output shaft of the driving motor 61 is a bevel gear, so that the driving motor 61 can be arranged parallel to the panel 10, which helps to reduce the thickness of the door lock. In other embodiments, the driving motor 61 can also choose to use other suitable transmission structures such as a belt transmission mechanism, a rack transmission mechanism, etc. to drive the driving member 62 to move, and is not limited to this.

[0043] The panel 10 is provided with a detector 71 for detecting whether the driving member 62 is in the second initial state. In this way, in conjunction with the control device such as the circuit board on the door lock, the driving motor 61 can be automatically controlled during use to reset the driving member 62, thereby ensuring the normal operation of the door lock, which is more reliable. In this embodiment, the detector 71 uses a contact switch, and a detection block is convexly provided on the driving member 62. The detection block can trigger the contact switch as the driving member 62 rotates. The structure is simple and reliable, the cost is low, and it is easy to process, assemble and control. In other embodiments, the detector 71 can also use other commonly used detection structures such as infrared sensors and Hall sensors, but is not limited to this.

[0044] In this embodiment, a first torsion spring 72 is provided between the handle 20 and the panel 10, for driving the handle 20 to rotate and reset. In addition, the free member 30, the driving member 62, the driving motor 61 and the transmission mechanism thereof are all installed in a box body 11, that is, a modular structure is formed, and a rotatable connecting member 23 is added in the box body 11, and the connecting member 23 protrudes out of the box body 11. The connecting member 23 can be regarded as a part of the handle 20 in the present invention, and is used to connect with the gripping portion of the handle 20, so that processing and assembly are convenient, which helps to reduce production costs and improve production efficiency.

[0045] In addition, a second torsion spring 73 is provided between the free member 30 and the panel 10, for driving the free member 30 to rotate and reset to the first initial state. In this way, on the one hand, the free member 30 can be driven to rotate and reset without the aid of the drive motor 61, which helps to extend the battery life. On the other hand, when the drive motor 61 fails or is damaged, the second torsion spring 73 can also reset the free member 30 and maintain it in the first initial state, which helps to improve the anti-theft performance of the door lock.

[0046] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0047] Reference Figure 5, the second preferred embodiment of the present invention is different from the first preferred embodiment. In this embodiment, the driving member 62 is a gear rotatably arranged on the panel 10, the clearance structure is a notch 64 formed by the driving member 62 lacking part of the teeth, and the free member 30 has a gear portion for meshing with the driving member 62; when the free member 30 is in the first initial state and the driving member 62 is in the second initial state, the gear portion and the driving member 62 form a non-meshing state through the notch 64.

[0048] Refer to Figure 6 , the third preferred embodiment of the present invention is different from the first preferred embodiment. In this embodiment, the driving member 62 is a rack movably arranged on the panel 10, the clearance structure is a notch 64 formed by the driving member 62 lacking part of the teeth, and the free member 30 has a gear portion for meshing with the driving member 62; when the free member 30 is in the first initial state and the driving member 62 is in the second initial state, the gear portion and the driving member 62 form a non-meshing state through the notch 64.

[0049] Only several preferred clearance structures are shown above. In other embodiments, other suitable structures can also be selected for the clearance structure, and it is not limited thereto.
