[0002] In order to realize automatic closing and locking of the door on the door leaf, a door closer and an electric lock are often used simultaneously. For example, the Chinese patent document "Automatic Control System for Anti-theft Door" with publication number "CN1102231A" has made such an attempt.

[0003] With the development of technology, electromagnetic locks (also called magnetic locks) are now commonly used in electric control locks. For example, the Chinese patent document with the authorization announcement number "CN2893082Y" uses a door closer and an electromagnetic lock on a door leaf at the same time. Such a structure not only makes the installation of two sets of devices cumbersome, but also increases the damage to the door. In addition, conventional electromagnetic locks themselves have the disadvantages of being bulky and consuming electricity when maintaining the door locked.

[0004] The Chinese patent document with the authorization announcement number "CN210316887U" discloses "an intelligent electric lock with auxiliary door closing function", and discloses a solution combining a door closer with an electric lock.

[0005] The present invention aims to provide another new structure, which realizes the combination of a door closer and an electric control lock. Summary of the invention

[0078] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0079] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0080] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0081] like Figure 1 The schematic diagram of the electric lock with door closer applied to the door and door frame is shown. Figure 1It is a top view with partial perspective. The door closer 1 is installed between the door DR and the door frame DF, and the door DR is hinged to the side of the door frame DF. The door closer 1 includes a door closer body 18, a rocker arm 19, a slider 20 and a guide rail 5, and the slider 20 is slidably arranged in the guide rail 5. The door closer body 18 is installed on the door DR, and the guide rail 5 is installed on the top lower surface of the door frame DF. A slidable slider 20 is arranged in the guide rail 5, and the slider 20 is hinged to one end of the rocker arm 19, and the other end of the rocker arm 19 is hinged to the door closer body 18, so that the slider 20 is linked to the opening and closing of the door DR. During the opening process of the door DR, the door closer body 18 stores energy, and when the power to open the door DR is removed, the door closer body 18 drives the rocker arm 19 to swing to release the stored energy to close the door DR.

[0082] Figure 1 Position A in the middle refers to the main installation position of the door locking function component in the electric lock with door closer in this example.

[0083] Figure 2 The three-dimensional schematic diagram (with partial perspective) of the door and door frame to which the present invention is applied is shown. The electric control lock with door closer of the first embodiment is used.

[0084] Example 1

[0085] like Figure 3 as well as Figure 4 The electric lock with door closer is shown, wherein the door closing functional components except the guide rail 5 are hidden. Figure 4 yes Figure 3 Enlarged view of point B in the middle. The door closer can adopt various conventional door closers using guide rails.

[0086] like Figure 3 , especially Figure 4 A fixed movable block 16 is provided in the guide rail 5. Before installation, the fixed movable block 16 can be slidably adjusted in position in the guide rail 5, and is fixed by riveting or screwing after the position is adjusted. A lock tongue 3 is rotatably provided on the fixed movable block 16. The lock tongue 3 is installed on the fixed movable block 16 through a rotating shaft 22, and the outer end of the lock tongue 3 extends out of the guide rail 5. An adsorption plate 13 is rotatably provided at the other end of the lock tongue 3 relative to its outer end.

[0087] The fixed movable block 16 is also provided with a driving mechanism 4, namely an electromagnetic induction coil 11, which is provided corresponding to the adsorption plate 13, so as to attract the adsorption plate 13, and then drive the lock tongue 3 to rotate clockwise during attraction. The rotating shaft 22 is provided with an assisting member 10, namely a torsion spring, which is connected to the lock tongue 3, and the assisting member 10 assists the lock tongue 3 to rotate counterclockwise (after the electromagnetic induction coil 11 is powered off). It is also possible not to provide the assisting member 10, and the lock tongue 3 can rotate counterclockwise to recover due to the imbalance of the center of gravity of the lock tongue 3 itself (after the electromagnetic induction coil 11 is powered off).

[0088] The electric lock with door closer also includes a lock block 2, in which a lock slot 6 is provided. The lock block 2 is mounted on the upper part of the door (see Figure 1 and Figure 2 ), when at least a part of the lock tongue 3 is located in the lock groove 6, it is in the locked door state, and when the lock tongue 3 is located outside the lock groove 6, it is in the unlocked state.

[0089] like Figure 5 as well as Figure 6 , Figure 5 Corresponds to Figure 3 , Figure 3 The electromagnetic induction coil 11 is in a power-off state. Figure 5 The electromagnetic induction coil 11 is in a powered state. Figure 6 yes Figure 5 Enlarged view of point B'.

[0090] like Figure 6 After the electromagnetic induction coil 11 is energized, the electromagnetic induction coil 11 attracts the adsorption plate 13, thereby driving the lock tongue 3 to rotate clockwise to unlock. In this example, the adsorption plate 13 is rotatably connected to the lock tongue 3, so that the adsorption plate 13 is close to the electromagnetic induction coil 11, thereby improving the adsorption force during adsorption.

[0091] like Figure 2 The electric lock with door closer in this example also includes an access control system 21. The access control system 21 can use conventional unlocking methods such as fingerprint, password, face recognition, remote control and access control card in the art. The access control system 21 is connected to the drive mechanism 4 and sends a command to energize the electromagnetic induction coil 11 after verification, so that the lock tongue 3 is separated from the lock slot 6 and unlocked. Figure 6 Unlocked state.

[0092] In this example, since the main components that play the door locking function are integrated into the fixed movable block 16, the lock tongue 3, the electromagnetic induction coil 11, and the adsorption plate 13 can be pre-installed on the fixed movable block 16, and then installed together in the guide rail 5, so as to facilitate installation, improve installation efficiency, and facilitate disassembly during later maintenance. Of course, it is also possible not to set the fixed movable block 16, and directly install the lock tongue 3, the electromagnetic induction coil 11, and the adsorption plate 13 in the guide rail 5, such as the embodiments 2-4 described later.

[0093] In order to achieve unlocking in case of power outage or emergency, this example also provides a manual unlocking method.

[0094] like Figure 4 The lock slot 6 is also provided with an auxiliary push block 7, which can push the lock tongue 3 away from the lock slot 6 by sliding the auxiliary push block 7. The lock slot 6 is also provided with a cam 8, which pushes the auxiliary push block 7 upward by rotating the cam 8, thereby pushing the lock tongue 3 out of the lock slot 6 (see Figure 6). In order to unlock the door by key outside, the cam 8 is integrated on the lock cylinder 9, and the lock cylinder 9 is arranged in the lock block 2. Inside the door, the cam 8 is unlocked without the need for a key. Figure 7 and Figure 8 , Figure 7 and Figure 8 They are Figure 3 and Figure 5 Side view (section view), Figure 7 The door is locked. Figure 8 It is unlocked state, and the lock core 9 extends into the door (i.e., the left side) with a wrench mounting end 24. An adjustable wrench is installed on the wrench mounting end 24, and the door can be unlocked by rotating the adjustable wrench.

[0095] like Figure 7 In order to facilitate closing the door, a bevel 23 is provided on the lock tongue 3, so that the upper edge of the door leaf drives the lock tongue 3 to rotate and unlock the door by the power of the door closer 1. Of course, the bevel 23 can also be omitted, for example, by setting the access control system to delay power off after unlocking to achieve smooth closing of the door closer.

[0096] In summary, if Figure 2 , Figure 4 and Figure 6 In this example, the electric lock with door closer installs the main components that play the locking function in the guide rail 5 of the door closer 1, thereby realizing the automatic door closing and door locking functions at the same time, and the structure is simple. During construction, compared with installing the door closer and electromagnetic lock separately, the damage to the door is reduced, and the construction time is also reduced. In addition, in the locked door state, since the electromagnetic induction coil 11 is in a power-off state, electric energy is saved, and the energy-saving effect is more obvious when used for normally closed doors. In this example, the door locking function is realized through the compact structure of the lock tongue 3, the drive mechanism 4, and the lock block 2. In addition, a variety of unlocking methods are realized by integrating the access control system 21 and the lock core 9. Not only can it be unlocked by conventional methods of the access control system such as fingerprints, passwords, and access control cards, but it can also be unlocked by manual unlocking methods such as keys (outside the door) and adjustable wrenches (inside the door) in power outages or emergencies.

[0097] Example 2

[0098] like Figure 9-12 Example 2 is shown. Fig. 9 and Fig.11 They are respectively locked and unlocked. Fig.10 for Fig. 9 The enlarged view of point C, Fig.12 for Fig.11 Enlarged view of C'.

[0099] like Fig.10 The difference between this example and Example 1 mainly lies in the structure of the driving mechanism 4.

[0100] like Fig.10 The driving mechanism 4 of this example includes a tubular electromagnetic induction coil 11 , a core rod 14 is passed through the electromagnetic induction coil 11 , and the left end of the core rod 14 is connected to the lock tongue 3 through a connecting rod 26 . Fig.10 The electromagnetic induction coil 11 is in a power-off state, and the lock tongue 3 is in a locked door state in the lock groove 6. Fig.12 When the electromagnetic induction coil 11 is energized by the access control system, a magnetic field is generated in the electromagnetic induction coil 11, and the magnetic field drives the core rod 14 to move rightward, thereby driving the lock tongue 3 to disengage from the lock slot 6 to complete unlocking.

[0101] like Fig.10 and Fig.12 In order to assist the lock tongue 3 to return to the locked state, an assisting member 10 is also provided. In this example, the assisting member 10 is a straight spring. The assisting member 10 is connected between the right end of the core rod 14 and the electromagnetic induction coil 11. Fig.10 The assist member 10 (straight spring), Fig.12 The assisting member 10 (straight spring) is in a stretched state. The assisting member 10 essentially acts on the lock tongue 3, that is, it is indirectly connected to the lock tongue 3 and indirectly drives the lock tongue 3 to rotate counterclockwise and return. In other embodiments, the assisting member 10 can also be replaced by an elastic body such as a rubber band.

[0102] like Fig.10 In order to control the stroke of the core rod 14, a limit plate 25 is also provided on the core rod 14. Fig.12 When the limiting piece 25 is pressed against the electromagnetic induction coil 11, the core rod 14 is restricted from continuing to move to the right.

[0103] This example can produce basically the same beneficial effects as Example 1, such as simple structure, little damage to the door during construction, short construction time, energy saving, and the ability to achieve multiple unlocking methods.

[0104] Example 3

[0105] like Figure 13-16 Example 3 shown, Fig.13 and Fig.15 They are respectively locked and unlocked. Fig.14 for Fig.13 The enlarged picture of D, Fig.16 for Fig.15 Enlarged view of D'.

[0106] like Fig.14 The difference between this example and Example 1 is mainly in the structure of the driving mechanism 4.

[0107] like Fig.14The driving mechanism 4 of this example includes a motor 12, the output end of which is connected to the lock tongue 3 through a gear transmission member and a connecting rod 26, thereby driving the lock tongue 3 to rotate. The motor 12 converts the shaft rotation into a linear motion through gear transmission, thereby pulling the lock tongue 3 to rotate. This implementation method is already a prior art, but it is not easy to think of using it in this example.

[0108] like Fig.16 After receiving the unlocking command from the access control system, the motor 12 drives the lock tongue 3 to rotate clockwise to complete the unlocking; and after the person passes through, according to the door locking command from the access control system, the motor 12 drives the lock tongue 3 to rotate counterclockwise to lock the door. In order to control the rotation amplitude of the lock tongue 3, a limit switch 15 is also provided in this example. The contact end of the limit switch 15 is provided in the active path of the lock tongue 3. When the lock tongue 3 rotates clockwise to a predetermined position, the limit switch 15 is triggered to cut off the power to the motor 12.

[0109] This example can still produce basically the same beneficial effects as Example 1, such as simple structure, little damage to the door during construction, short construction time, energy saving, and the ability to achieve multiple unlocking methods.

[0110] Example 4

[0111] like Figure 17-20 Example 4 shown, Fig.17 and Fig.19 They are respectively locked and unlocked. Fig.18 for Fig.17 The enlarged view of point E, Fig. 20 for Fig.19 Enlarged view of E'.

[0112] like Fig.18 The difference between this example and Example 1 mainly lies in the structure of the driving mechanism 4 and the structure of the lock tongue 3.

[0113] The driving mechanism 4 of this example still uses the motor 12. The output end of the motor 12 drives the lever 17 to rotate through the connecting rod 26, and the lever 17 drives the lock tongue 3 to slide up and down.

[0114] The bolt 3 of this embodiment moves by sliding up and down, while the bolt 3 of the above embodiments 1-3 moves by rotating. In this embodiment, the bolt 3 is assisted to return downward by the assisting member 10 (straight spring), and the travel of the bolt 3 is controlled by the limit switch 15.

[0115] This example can also produce basically the same beneficial effects as Example 1, such as simple structure, little damage to the door during construction, short construction time, energy saving, and the ability to achieve multiple unlocking methods.

[0116] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
