DETAILED DESCRIPTION

[0035] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0036] Please refer to Figure 1-3 A smart chain lock includes a lock body 1, wherein the lock body 1 includes a power supply device 4, a lock core 6, a lock rod 3, a pressing portion 2, a drive control device 5, a lock tongue 7 and a return portion 11.

[0037] In this embodiment, the locking rod 3 is a U-shaped locking rod 3. Of course, it can also be a chain lock. The present invention has no specific limitation on the shape of the locking rod 3. This embodiment takes the U-shaped locking rod 3 as an example to illustrate the structure and working principle of the present invention.

[0038] The U-shaped locking rod 3 has two ends, one end of the locking rod 3 (hereinafter referred to as the first end) is rotatably connected to the lock body 1; the other end of the locking rod 3 (hereinafter referred to as the second end) is engaged or disengaged with the lock tongue 7, thereby achieving locking or unlocking. In addition, for the convenience of expression, the direction from the first end of the U-shaped locking rod 3 toward the second end of the U-shaped locking rod 3 is defined as the length direction below, the direction perpendicular to the length direction is defined as the width direction, and the direction perpendicular to both the length direction and the width direction is called the height direction.

[0039] The restoring part 11 is preferably a spring. Of course, other linear elastic components can also be used as the restoring part 11 of the present invention.

[0040] The drive control device 5 is used to drive the lock core 6 to approach or move away from the lock tongue 7. The drive control device 5 integrates drive and control, can receive external drive signals and drive the lock core 6 to move, and the power supply device 4 is electrically connected to the drive control device 5.

[0041] In the traditional key unlocking, the key needs to be inserted into the keyhole for a long time and twisted in the unlocking direction, and the twisted state is maintained so that the lock core 6 is always kept away from the lock rod 3 to achieve locking or closing. The user's fingers will feel pain when twisting the key for a long time, and the lock core 6 is in a taut state for a long time, which will greatly reduce the service life of the lock.

[0042] Therefore, in this embodiment, the lock core 6 is indirectly connected to the second end, and the specific connection method is: the return part 11 is arranged between the lock tongue 7 and the lock body 1, one end of the lock tongue 7 is in contact with the lock rod 3, and the other end of the lock tongue 7 is clamped with the second end.

[0043] In this embodiment, the lock core 6 only has a limiting function. Since the spring is in a pre-tightened state from the beginning, regardless of whether there is a contact relationship between the lock core 6 and the lock tongue 7, the spring with pre-tightening force always keeps the lock tongue 7 and the second end in a clamped state, thereby realizing the separation of the unlocking action and the action of the lock rod 3 disengaging from the lock tongue 7.

[0044] To further illustrate the movement relationship between the above structures when using the lock:

[0045] When unlocking is required, the driving control device 5 moves the lock core 6 away from the lock tongue 7. At this time, since the spring has a pre-tightening force, the lock tongue 7 still maintains a clamping state with the second end under the action of the spring force, and the lock is still in a locked state. The pressing part 2 is transmission-connected with the lock tongue 7 and extends out of the lock body 1. The user only needs to gently press the pressing part 2 on the outside of the lock body 1 to make the lock tongue 7 move toward the spring and away from the second end. The spring arranged between the first end and the lock body 1 makes the lock rod 3 pop out of the lock body 1, thereby making the second end pop out of the lock body 1.

[0046] When locking is required, the user only needs to gently press the pressing part 2 on the outside of the lock body 1 to make the lock tongue 7 move toward the spring, and then press the second end into the lock body 1. At this time, release the pressing part 2, the spring automatically resets, and the lock tongue 7 is engaged with the second end. Finally, the driving control device 5 makes the lock core 6 close to the lock tongue 7, and the other end of the lock tongue 7 abuts against the lock core 6, making it impossible to press the pressing part 2, thereby achieving the locking action.

[0047] The above structure has the following effects: the separately arranged pressing part 2 separates the unlocking action from the action of the lock core 6 disengaging from the lock tongue 7, thereby avoiding finger pain caused by the user twisting the key for a long time. At the same time, the entire unlocking process is divided into two steps, thereby avoiding the reduction in the life of the lock due to the lock core 6 being in a stressed state for a long time. At the same time, since the spring is the main bearer of the force, even if the spring is damaged, it is very convenient to replace, which is simple and practical.

[0048] At the same time, since the lock of the present invention is electrically driven, there is a key problem that when charging is required, the entire lock needs to be carried for charging, and the lock is very heavy and inconvenient to carry.

[0049] Therefore, in order to solve the above problems, the present embodiment has the following connection relationship:

[0050] Please refer to Figure 1 , Fig. 9 , Fig.10 , Fig.14 , Fig.15 The power supply device 4 is detachably arranged on the lock body 1. The specific installation relationship is that the power supply device 4 is clamped on the lock body 1 between the first end and the second end. That is to say, when the lock is in a locked state, the power supply device 4 cannot be removed from the lock body 1. When the lock is in an unlocked state and the second end is turned away from the lock body 1, there is no blocking effect on the power supply device 4, and then the power supply device 4 can be removed from the lock body 1.

[0051] In summary, the present invention has at least the following effects:

[0052] 1. When the lock needs to be charged, the power supply device 4 can be removed from the lock body 1 to replace the battery, or the lock body 1 can be taken back for charging. It is light enough and easy to carry.

[0053] 2. The power supply device 4 is arranged on the inner side of the lock rod 3. When the lock is in the locked state, the power supply device 4 cannot be removed from the lock body 1, which has a high safety factor and excellent anti-theft function.

[0054] 3. The pressing part 2 is separately provided, so that the unlocking action is separated from the action of the lock core 6 disengaging from the lock tongue 7, thereby avoiding finger pain caused by the user twisting the key for a long time. At the same time, the setting of the pressing part 2 divides the entire unlocking process into two steps, thereby avoiding the reduction of the lock life caused by the lock core 6 being in a stressed state for a long time. At the same time, since the spring is the main force bearer, even if the spring is damaged, it is very convenient to replace, which is simple and practical.

[0055] As a further improvement of the above solution, please refer to Figure 1The driving control device 5 includes a password input panel 53, a control component 52 and a driving motor 51. The password input panel 53 is electrically connected to the control component 52. The purpose of driving the lock cylinder 6 can be achieved by presetting a password in the control component 52 and then inputting the password. In this way, the user does not need to carry a key, but only needs to remember the password, which is very convenient to use.

[0056] Please refer to Fig. 9 The lock body 1 is provided with a first accommodating chamber 12 and a second accommodating chamber 13. The first accommodating chamber 12 and the second accommodating chamber 13 are both rectangular and distributed along the length direction. A partition plate 14 is provided between the first accommodating chamber 12 and the second accommodating chamber 13. When used on rainy days, muddy water may enter the second accommodating chamber 13 from the lock hole on the lock body 1, and then enter the first accommodating chamber 12 from the second accommodating chamber 13. Circuit components are arranged in the first accommodating chamber 12, and muddy water may damage the circuit components. Therefore, in order to prevent this phenomenon from occurring, a partition plate 14 is provided to isolate the drive control device 5 from the lock tongue 7, so as to prevent the muddy water entering from the lock tongue 7 from causing irreversible damage to the drive control device 5.

[0057] Please refer to Figure 8 The lock core 6 includes a linkage block 61 and a linkage rod 62. The linkage block 61 and the drive motor 51 are arranged in the first accommodating chamber 12. The linkage rod 62 is partially arranged in the first accommodating chamber 12. The linkage block 61 is in the shape of a long strip. The linkage block 61 is provided with an internal thread. The output shaft of the drive motor 51 is provided with an external thread. The internal thread and the external thread are matched and connected, so that the linkage block 61 and the output shaft of the drive motor 51 are threadedly connected, thereby converting the rotation of the drive motor 51 into a linear motion of the lock core 6 along the length direction. Since the threaded connection may be stripped after repeated use, the drive motor 51 of the present invention may also adopt a voice coil motor. The output end of the voice coil motor is fixedly connected to the lock core 6, and the motion along the length direction is directly output. It has a long service life and high transmission accuracy.

[0058] Please refer to Figure 2 , Figure 8 , Fig. 9The partition plate 14 is provided with a through hole 141, and the linkage rod 62 extends into the second accommodating chamber 13 through the through hole 141, so as to transmit the force along the length direction output by the driving motor 51 to the lock tongue 7. The setting of the through hole 141 becomes the premise for the setting of the partition plate 14, that is, since the force on the lock core 6 can be transmitted to the lock tongue 7 through the through hole 141 on the partition plate 14, it is possible to set the partition plate 14. However, since there may be muddy water in the second accommodating chamber 13, a sealing ring (not marked in the figure) is provided on the through hole 141 to further prevent the first accommodating chamber 12 from water ingress. The control component 52 is arranged above the first accommodating chamber 12, so that it can be conveniently connected to the password input panel 53 arranged on the lock, and the structural design is reasonable.

[0059] Please refer to Figure 7 In some embodiments of the present invention, the lock tongue 7 includes a first main body portion 71 and a first locking portion, the first locking portion is matched and connected with the second end of the lock rod 3, the first main body portion 71 is a rectangular frame, and the lock core 6 and the second end are respectively arranged on both sides of the rectangular frame.

[0060] The first main body portion 71 includes a through hole 715 and a notch 712. The through hole 715 is circular in shape, matching the shape of the linkage rod 62 of the lock core 6. Of course, the linkage rod 62 and the through hole 715 can be rectangular or triangular in shape. The circular linkage rod 62 is easy to process and is therefore preferred.

[0061] The notch 712 is connected to the through hole 715 , and the lock core 6 can be inserted from the through hole 715 , thereby extending into the first body portion 71 . First inclined surfaces 711 are provided on both sides of the notch 712 , and the inclination angle of the first inclined surface 711 is not specifically limited.

[0062] Please refer to Figure 4-6 The pressing portion 2 is provided with a protrusion 21, and the protrusion 21 is movably arranged in the notch 712. Second inclined surfaces 22 are provided on both sides of the protrusion 21. The inclination angle of the second inclined surface 22 is the same as the inclination angle of the first inclined surface 711, thereby realizing a transmission connection between the first inclined surface 711 and the second inclined surface 22. The matching transmission connection between the inclined surfaces can greatly reduce the driving pressure and protect the first main body portion 71. The pressing portion 2 is perpendicular to the upper surface of the first main body portion 71 and extends from the top (height direction) of the lock body 1.

[0063] The protrusion 21 is arranged in the middle and corresponds to the notch 712, so as to prevent the inclined surface from slipping in the width direction when sliding in the length direction, that is, it plays a positioning role. At the same time, it cooperates with the linkage rod 62 to play a limiting role.

[0064] The specific working principle of the above structure is:

[0065] Locked state: when the driving motor 51 drives the linkage rod 62 of the lock core 6 to extend into the first main body part 71, it presses against the protrusion 21 of the pressing part 2, so that the protrusion 21 cannot be pressed downward, and the second inclined surface 22 cannot slide relative to the first inclined surface 711, so that the first main body part 71 cannot move toward the linkage block 61 of the lock core 6, so that the lock tongue 7 remains connected to the second end.

[0066] Unlocked state: when the driving motor 51 drives the linkage rod 62 of the lock core 6 away from the first main body part 71, the movement restriction on the protrusion 21 is released, so that the protrusion 21 can be pressed downward, and the second inclined surface 22 slides relative to the first inclined surface 711, so that the first main body part 71 moves toward the linkage block 61 of the lock core 6, so that the lock tongue 7 is disconnected from the second end.

[0067] Please refer to Figure 12-13 In some embodiments of the present invention, the lock tongue 7 includes a second body portion 73 and a second locking portion 731, the second locking portion 731 is matched and connected with the second end of the lock rod 3, and the lock core 6 and the second end are respectively arranged on both sides of the second body portion 73.

[0068] Please refer to Fig.11 The second locking portion 731 is matched and connected with the second end, the second main body portion 73 includes a fixed platform 732 and an extension platform 74, the fixed platform 732 is a rectangular frame, and an extension platform 74 is provided above the fixed platform 732, and the extension platform 74 and the fixed platform 732 are integrally formed, the pressing portion 2 includes a pressing block 24 and a pressing handle 23, the second accommodating cavity 13 is provided with a limiting buckle 16, and the pressing handle 23 is arranged in the limiting buckle 16 to prevent the pressing handle 23 from shaking in the width direction when pressed, and one side of the extension platform 74 abuts against the pressing block 24, and the pressing handle 23 is arranged along the length direction and extends out of the lock body 1 along the length direction.

[0069] The specific working principle of the above structure is:

[0070] Locked state: when the driving motor 51 drives the linkage rod 62 of the lock core 6 to approach the first main body part 71, the linkage rod 62 presses against the extension platform 74, so that the protrusion 21 cannot be pressed downward, thereby making the first main body part 71 unable to move toward the linkage block 61 of the lock core 6, so that the lock tongue 7 remains connected to the second end.

[0071] Unlocked state: when the driving motor 51 drives the linkage rod 62 of the lock core 6 away from the first main body part 71, the linkage rod 62 no longer presses against the extension platform 74, so that the protrusion 21 can be pressed downward, thereby causing the first main body part 71 to move toward the linkage block 61 of the lock core 6, thereby causing the lock tongue 7 to be disconnected from the second end.

[0072] Since it is inconvenient to specifically control the number of rotations of the driving motor 51 and the moving distance of the linkage block 61 , it is necessary to control the moving distance of the linkage block 61 so that the locking and unlocking processes proceed smoothly.

[0073] Please refer to Fig.12 As a further improvement of the above scheme, the linkage block 61 is provided with a groove 611, which is a rectangular groove 611. A travel switch 54 is fixedly provided on the side of the first accommodating cavity 12. The control button of the travel switch 54 is arranged in the groove 611. The travel switch 54 is electrically connected to the drive control device 5. When the linkage block 61 moves along the length direction, the control button of the travel switch 54 will be driven to move. For example, it is only necessary to preset two nodes in the travel switch 54. When the movement reaches the node, the drive motor 51 stops working. When the drive motor 51 is in the node, the drive motor 51 can be operated to realize the control of the rotation of the drive motor 51.

[0074] Please refer to Fig.13 As a further improvement of the above solution, a plurality of blind holes 75 are provided on the side of the locking tongue 7 facing the partition plate 14. The blind holes 75 can accommodate the spring to prevent the spring from moving due to deformation.

[0075] An opening 751 is provided between the blind hole 75 and the locking tongue 7. Since there may be water vapor in the second accommodating cavity 13 and the spring is in a taut state for a long time, the opening 751 is provided on the side of the blind hole 75 so that the spring can be slightly bent and deformed toward the side, thereby improving the stress condition of the spring. At the same time, the water vapor in the blind hole 75 can also be discharged, and the water vapor will not gather inside the blind hole 75, thereby causing the spring to rust, thereby increasing the service life of the spring.

[0076] Please refer to Figure 9-10 In some embodiments of the present invention, a blocking surface 17 and a mounting surface 18 are provided on one side of the lock body 1 close to the locking rod 3, the blocking surface 17 is perpendicular to the mounting surface 18, the mounting surface 18 is provided with a plurality of blocking blocks 181, and the power supply device 4 is provided with a plurality of connecting blocks 41.

[0077] In this embodiment, there are four blocking blocks 181, which are divided into two rows and symmetrically arranged on the mounting surface 18. The power supply device 4 is provided with four connecting blocks 41, which are symmetrically arranged on the side of the power supply device 4. The connecting blocks 41 correspond one-to-one with the blocking blocks 181, and the connecting blocks 41 are matched and connected with the blocking blocks 181, so that the power supply device 4 is hung on the lock body 1.

[0078] The support block 181 includes a first side wall 1811, a second side wall 1812 and a third side wall 1813. The first side wall 1811 is perpendicular to the second side wall 1812, and the third side wall 1813 is perpendicular to both the first side wall 1811 and the second side wall 1812. The first side wall 1811, the second side wall 1812 and the third side wall 1813 form a non-enclosed receiving cavity, thereby accommodating the connecting block 41, and then hanging the power supply device 4 on the lock body 1.

[0079] Please refer to Figure 12-15 In some embodiments of the present invention, a third accommodating cavity 15 is provided on one side of the lock body 1 close to the locking rod 3. The shell of the third accommodating cavity 15 half-wraps the power supply device 4, thereby providing a certain protection for the power supply device 4. The third accommodating cavity 15 is provided with an observation hole 151, an installation cavity 152 and a limit bayonet 153. The observation hole 151 is connected to the installation cavity 152. The power supply device 4 is provided with a first boss 42 and a second boss 43. When the power supply device 4 is installed on the lock body 1, the first boss 42 extends into the installation cavity 152.
