Description

Technical Field

[0001] This utility model relates to the field of door lock technology, specifically to an electronic door lock structure based on mechanical linkage unlocking warning. Background Technology

[0002] As people's living standards improve, more and more families are choosing to install smart electronic door locks. Smart electronic door locks are usually unlocked by passwords and biometric information such as fingerprints and faces, so that people do not need to carry keys when they go out, which greatly improves the convenience of people's lives. However, smart electronic door locks do not make any noise when a key is inserted into the lock or turned during the unlocking process, making the whole unlocking process relatively quiet. If criminals steal the homeowner's door lock password or biometric information and try to unlock the door and illegally break in, or if a mischievous child in the neighborhood presses the door lock as a toy, the noise generated by the normal life of the people inside the house will make it difficult for the people inside the house to notice the sound of the door lock being pressed. This makes it difficult for the people inside the house to know in advance that someone is trying to open the door and take necessary precautions.

[0003] Based on the above, Chinese Patent No. CN211851308U discloses an intelligent electronic door lock, including a front lock body and a rear lock body.

Detailed Implementation

[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0023] like Figure 1-3 As shown, an electronic door lock structure based on mechanical linkage unlocking warning includes an outer lock box 1, a warning button 2, and a lock cylinder mechanism 3. The outer lock box 1 is hollow to form an inner cavity. The warning button 2 is located on one side of the outer lock box 1 and extends into the inner cavity. A delay switch 11 matching the warning button 2 is provided inside the inner cavity. A traction line 4 extending to the outside of the outer lock box 1 is provided on the side of the warning button 2 near the delay switch 11. An audible warning element 5 is provided at the end of the traction line. The lock cylinder mechanism 3 is located inside the inner cavity and has a square steel member 31 extending to the outside of the outer lock box 1.

[0024] This utility model is mainly used as a structure installed on the outside of an electronic door lock. This utility model is assembled with a bolt structure installed inside the security door, an inner lock box, an inner door handle, a deadbolt structure, a motor, etc., installed on the inside of the door to form an electronic door lock. The inner lock box also contains necessary components such as batteries and control circuit boards. The front side of the outer lock box 1 is provided with a fingerprint module 12 and a password module 13. The battery provides the necessary power for the operation of the control circuit board, fingerprint module 12, password module 13, motor, etc. The above-mentioned bolt structure, inner lock box, inner door handle, deadbolt structure, battery, control circuit board, fingerprint module 12, password module 13, motor, etc. are all accessories commonly used in electronic door locks on the market. Their structure and principle are common knowledge to those skilled in the art. Those skilled in the art can select appropriate accessories according to the functions required by the electronic door lock. Therefore, the structure and principle of the above-mentioned accessories will not be described in detail.

[0025] With the above structure, it should be further explained that the lock cylinder mechanism 3 is located near the bottom of the outer lock box 1. The outer lock box 1 is fixed to the security door via its back side relative to the lock cylinder mechanism 3. The security door has a suitable through hole through which the square steel piece 31 passes through to the inside of the security door and connects to the inner door handle. The square steel piece 31 passes through the lock tongue structure inside the security door. The square steel piece is rotated by a motor or the inner door handle, thereby driving the lock tongue structure to extend and retract to realize the operation of opening and closing the door. In addition, a protrusion is formed on the back of the outer lock box 1 relative to the lock cylinder mechanism 3 and is fixed to the security door, so that the outer lock box 1 near the top does not contact the security door and forms a large space. This space is used for the outer lock box 1 to act as an outer door handle during the opening process. The hand is placed in this space and the outer lock box 1 is pulled to realize the opening operation.

[0026] It should be noted that the delay switch 11 is preferably a contact-type delay switch. The delay switch 11 connects the circuit for a set time via contact and then automatically disconnects. The delay switch 11 is connected between the battery and the fingerprint module 12 and the password module 13. Under normal conditions, the delay switch 11 is in the off state, and the fingerprint module 12 and password module 13 have no power supply and cannot recognize fingerprints or press passwords. Therefore, it is impossible to open the door from the outside by recognizing fingerprints or pressing passwords. At this time, it is necessary to first press the warning button 2 to make it contact the delay switch 11. The warning button 2 has a pressing rod 21 extending towards the delay switch 11. The pressing rod 21 contacts the trigger button of the delay switch 11, temporarily closing the delay switch 11, allowing the fingerprint module 12 and password module 13 to connect to the battery and thus enabling fingerprint recognition and password entry. The door can be opened by fingerprint or password. The push rod 21 is covered with a return spring 22. One end of the return spring 22 abuts against the surface of the delay switch 11. The return spring 22 can elastically cause the warning button 2 to rebound and reset after being pressed, making it easy to press the warning button again when the lock needs to be unlocked next time. The above structure increases the operation before the user uses fingerprint verification or password to unlock the door, avoiding accidental operation when the user pulls the outer lock box 1. It can also prevent mischievous children in the neighborhood from pressing and playing with the door lock as a toy. In addition, the warning button 2 is located on the back of the outer lock box 1, making it difficult for people unfamiliar with the electronic door lock to know the correct unlocking procedure. Even if criminals steal the owner's fingerprint information or password, it will be difficult to unlock the door, thereby increasing the difficulty for criminals to break in and improving the security of the electronic door lock.

[0027] With the above structure, it should be further explained that the sound warning element 5 is located inside the security door. The sound warning element 5 is preferably a bell. When the warning button 2 is pressed, it will pull the traction line 4, thereby triggering the sound warning element 5 to emit a sound. Since pressing the warning button 2 is a necessary operation before unlocking with fingerprint or password, the homeowner can know that someone is preparing or attempting to unlock the door. Especially for people living alone, the fingerprint used for unlocking is usually known only to the homeowner, and the password is known only to the homeowner. The sound warning element 5 can remind the homeowner that someone is preparing or attempting to unlock the door, so that they can take preventive measures in advance, thereby improving the security of the door lock. It should be noted that a guide ring 6 is provided inside the inner cavity near the connection between the warning button 2 and the traction line 4. The traction line 4 passes through the guide ring 6 and extends to the outside of the outer lock box 1 and connects with the sound warning element 5. The guide ring 6 can ensure that the distance the traction line 4 is pulled is close to the distance the warning button 2 is pressed, avoiding insufficient pulling distance of the traction line 4 which would cause the sound warning element 5 to fail to emit a sound, and ensuring that the sound warning element 5 can normally warn people inside the house.

[0028] Furthermore, such as Figure 4As shown, the sound warning element 5 has a bell 51 inside. The fixing ring at the top of the bell 51 is fixed horizontally and vertically by two fixing springs 52. The end of the traction line 4 is fixed to the fixing ring at the top of the bell 51. When the traction line 4 is pulled, it will pull the bell 51 simultaneously. The elastic potential energy of the two fixing springs 52 that fix the bell 51 will change. When the force applied to the bell 51 by the traction line 4 is removed, the two fixing springs 52 will release the elastic potential energy and the bell 51 will swing and vibrate, thereby emitting a sound.

[0029] like Figure 3 As shown, in one of the preferred embodiments of this utility model, one end of the traction line 4 extends along the square steel member 31 to the outside of the outer lock box 1. The surface of the square steel member 31 is provided with several rotating levers 32. The rotation of the square steel member 31 causes the ends of the rotating levers 32 to abut against the traction line 4. During the unlocking process, the square steel member 31 needs to be rotated to drive the lock tongue structure to extend and retract. During the rotation of the square steel member 31, the rotating levers 32 will rotate simultaneously. The rotating levers 32 push the traction line 4 through their ends, causing the traction line 4 to vibrate or be continuously pulled, thereby triggering the sound warning element 5 to emit a sound, informing the people inside the house that the door lock is being opened, thus improving the security of the door lock.

[0030] like Figure 1 , 2 As shown, in one of the preferred embodiments of this utility model, the top of the lock cylinder mechanism 3 is provided with a guide pulley 33, and the traction line 4 is wound around the surface of the guide pulley 33 with one end extending upward to be fixedly connected to the side of the warning button 2, and the other end extending along the square steel piece 31 to the outside of the outer lock box 1 and fixedly connected to the sound warning element 5; the guide pulley 33 is used to adjust the direction of the traction line 4 extending outward from the outer lock box 1, so that the traction line 4 can extend along the square steel piece 31, making it easier for the square steel piece 31 to move the traction line by rotating the lever 32, and eliminating the need to make holes for the traction line in the security door, which can reduce the number of holes on the surface of the security door.

[0031] like Figure 5 As shown, in one of the preferred embodiments of this utility model, a door lock top cover 14 is fitted on the top of the outer lock box 1. The door lock top cover 14 extends horizontally toward one side of the outer lock box 1 and forms a shielding part. The shielding part of the door lock top cover 14 is located at the top of the front of the outer lock box 1. When the electronic door lock is installed in an open-air security door, the door lock top cover 14 can shield the outer lock box 1 from rain or sunlight, prevent the fingerprint module 12 or password module 13 from getting wet and affecting normal unlocking, and improve the durability of this utility model.

[0032] like Figure 1 , 5As shown, in one of the preferred embodiments of this utility model, a lock cylinder cover plate 15 is inlaid on one side of the outer lock box 1. The position of the lock cylinder cover plate 15 matches the lock cylinder mechanism 3. The lock cylinder cover plate 15 is fixed to the outer lock box 1 by means of buckles, etc. Electronic door locks may be unable to be unlocked by fingerprint or password due to factors such as power consumption in the battery or failure of the control circuit board. Therefore, the lock cylinder mechanism 3 is usually provided with a keyhole so that it can be unlocked by key. The lock cylinder cover plate 15 can be pried open to unlock by key.

[0033] In summary, this utility model can unlock the door using fingerprint module 12 or password module 13. Before unlocking, the warning button 2 needs to be pressed until it contacts the delay switch 11 to connect the circuit, thus avoiding accidental activation during the pulling of the security door and increasing the difficulty for unauthorized personnel to break in. At the same time, when the warning button 2 is pressed, it will pull the traction line 4 and trigger the sound warning element 5 to make a sound, reminding people inside the house that the door lock is preparing to be opened or is attempting to be opened, thereby taking necessary precautions and improving the security of the electronic door lock.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
